Abstract:

Nel dibattito inerente l'analisi fattoriale particolare attenzione ha avuto il tema della non unicità delle sue soluzioni. Alcuni autori hanno affrontato il tema dell'identificabilità del modello, ricercando condizioni necessarie e sufficienti perchè, data la distribuzione delle variabili osservate, i valori dei parametri del modello siano unici. Altri hanno messo in luce il problema dell'indeterminatezza dei valori dei fattori per cui, in generale, le soluzioni non sono uniche anche qualora i parametri del modello siano perfettamente identificabili. Un secondo argomento di ricerca inerente l'analisi fattoriale è stato quello della costruzione di modelli derivati dal modello fattoriale ma caratterizzati da maggior generalità. La tesi, oltre a descrivere le caratteristiche del modello lisrel in relazione agli altri modelli, mette in luce alcuni aspetti inediti del problema dell'identificabilità dei suoi parametri. La successiva individuazione delle condizioni necessarie e sufficienti per l'esistenza di una soluzione del modello permette di identificare che sotto il profilo analitico l'indeterminatezza delle variabili latenti è dovuta all'esistenza di una componente variabile nella soluzione stessa. Infine, la costruzione della matrice di covarianza tra soluzioni differenti porta ad individuare una misura dell'indeterminatezza e ad analizzare le relazioni con gli autovalori della matrice di covarianza delle soluzioni. La riflessione sui risultati raggiunti e una applicazione empirica permettono di rivelare l'esistenza di covarianze negative tra variabili latenti di soluzioni differenti

Abstract:

Der statistische Diskussionbeitrag untersucht, ob und wie sich Erwartungen und Stimmungen in der Wirtschaft bilden bzw. von welchen volkswirtschaftlichen Größen sie abhängen. Als Methodik werden Partial Least Squares (PLS) Modelle genutzt, eine Modellklasse der Pfadanalyse mit latenten Variablen. Die verwendeten Daten wurden vom Ifo-Institut und aus der amtlichen Statistik entnommen.
This paper analyses the development of sentiments and expectations in the German economy. The issue is how these expectatons are influenced by major macroeconomic variables like investments or unemployment. Several Partial Least Squares models (PLS) are used to estimate the relations. The data is derived from the German Ifo Institut and the official statistic.

Hydrossedimentological monitoring and modeling have been used as important tools to evaluate and simulate the hydrosedimentological processes in rural watersheds, in order to effectively propose conservation practices in environmentally sensitive locations. The objective of this research was to evaluate the performance of a physically based hydrological model (LISEM - Limburg Soil Erosion Model) in quantifying runoff and erosion in a rural catchment with high spatial variability (horizontally and vertically) physical and hydrological characteristics of the soil. The catchment has an area of 1.19 km2 and is situated in the northeastern region of the Rio Grande do Sul state, Brazil. Soils are characterized by reduction of water flow in the vertical soil profile either by the small thickness (Entisols and Inceptisols) or textural gradient between horizons (Ultisols) - and are associated with variations of relief, which is composed of soft hills in the top section and mountainous in the bottom section of the catchment. The predominant land use is tobacco farming (Nicotiana tabacum L.), where the surface layer of the soil is tilled to form ridges. In the first stage of the study, five slopes of the basin used for tobacco cultivation were sampled to characterize the physical and hydraulic properties at different points in the relief (top, middle slope and lowland) and four soil layers (0.00 to 0.04, from 0.20 to 0.24, from 0.40 to 0.44 and from 0.60 to 0,64 m). Field trials were also conducted to determine the infiltration rate on the slopes, and equations were also established to estimate the saturated hydraulic conductivity in each layer of soil sampled. In the second step, the LISEM model was calibrated to represent the hydrograph and sedimentograph of 20 rainfall events monitored in the river mouth from 2009 to 2012. The results of the first stage show that there is horizontal and vertical variability of physical and hydraulic properties on the slopes, being that the hillsides have a higher saturated hydraulic conductivity due to its coarser texture. Both the hydraulic conductivity and the infiltration rate were effective in identifying the horizontal variability of water flow on the slopes. The hydraulic conductivity can be estimated with good accuracy when variables from subsoil layers, for example, the total sand content, are used. The results of the second stage of the study revealed that the LISEM had a good performance in modeling the hydrograph. However, it was not possible to represent the sedimentograph, and there was an overestimate in sediment production. The model s equations related to erosion do not represent the dynamics that occur in this catchment.
O monitoramento e a modelagem hidrossedimentológica têm sido utilizados como ferramentas importantes para avaliar e simular os processos hidrossedimentológicos em bacias hidrográficas rurais, com o intuito de propor, de forma eficaz, práticas conservacionistas em locais ambientalmente frágeis. O objetivo desta pesquisa foi avaliar o desempenho de um modelo hidrológico de base física (LISEM Limburg Soil Erosion Model) em quantificar o escoamento superficial e o processo erosivo em uma bacia hidrográfica rural com grande variabilidade espacial (no sentido horizontal e vertical) das características físico-hídricas de solo. A bacia hidrográfica possui 1,19 km2 e está situada na região nordeste do estado do Rio Grande do Sul, Brasil. Os solos são caracterizados pela redução do fluxo de água na direção vertical do perfil de solo seja pela pequena espessura (Neossolos e Cambissolos) ou pelo gradiente textural entre horizontes (Argissolos) e estão associados às variações do relevo, que é ondulado na fração superior e montanhoso na fração inferior da bacia. O uso do solo predominante é o cultivo do tabaco (Nicotiana tabacum L.), em que a camada superficial do solo é revolvida para a construção de camalhões. Na primeira etapa do estudo, cinco encostas da bacia utilizadas para o cultivo do tabaco foram amostradas para caracterização das propriedades físico-hídricas em diferentes pontos do relevo (topo, meia encosta e várzea) e em quatro camadas de solo (0,00 a 0,04, 0,20 a 0,24, 0,40 a 0,44 e 0,60 a 0,64 m). Também foram realizados ensaios de campo para determinação da taxa de infiltração básica nas encostas e, ainda, foram construídas equações para estimativa da condutividade hidráulica saturada em cada camada de solo amostrada. Na segunda etapa, o modelo LISEM foi calibrado para representar o hidrograma e o sedimentograma de 20 eventos monitorados no exutório da bacia entre no período de 2009 a 2012. Os resultados da primeira etapa comprovam que há variabilidade horizontal e vertical das propriedades físico-hídricas nas encostas, sendo que a meia encosta apresenta maior condutividade hidráulica saturada devido à textura mais grosseira neste local. Tanto a condutividade hidráulica quanto a taxa de infiltração básica foram eficazes em identificar a variabilidade horizontal do fluxo de água nas encostas. A condutividade hidráulica saturada pode ser estimada com boa precisão quando são usadas variáveis das camadas subsuperficiais do solo como, por exemplo, o teor de areia total. Os resultados da segunda etapa do estudo revelaram que o LISEM apresentou bom desempenho na modelagem do hidrograma. No entanto, não foi possível a representação do sedimentograma, sendo que houve superestimativa da produção de sedimentos. As equações do modelo relacionadas com o processo erosivo não representam a dinâmica que ocorre nesta bacia hidrográfica.

Abstract:

Newly listed firms have a short history of stock value, and may initially not rely on stock price information in incentive contracting as much as seasoned firms. In this thesis, I examine managerial incentive contracts in newly listed firms by comparing CEO compensation between IPO firms and seasoned firms. For IPOs listed on NYSE from 1993 to 2001, a matching sample of seasoned firms was obtained according to criteria in industry, size and book-to-market ratio. By examining the multi-dimensions of CEO incentives, including cash compensation, option grants, stock ownership, and dismissal for the first six years after listing, I document significant differences between IPOs and seasoned firms. I find that while the sensitivity of short-term incentive pay to shareholder return is lower in IPOs than in seasoned firms, long-term incentives from CEO stock ownership are significantly more important in newly listed firms. Moreover, although CEO turnover in an IPO firm is lower, it depends on both stock-price return and accounting performance. These IPO-seasoned differences diminish over time and disappear in three to five years. My findings suggest that to motivate the manager of a newly listed firm, the board avoids short-term uncertainty associated with new stocks while emphasizing the role of shareholder value in the long run.

Abstract:

O presente trabalho tem por objetivo desenvolver um modelo para acompanhamento e estimativa da produtividade da cultura da soja (Glycine max L. Merril)em um sistema de informações geográficas (SIG), a partir de um modelo agrometeorológico pontual e imagens NOAA-AVHRR. A integração do modelo e da base de dados foi realizada através do aplicativo SPRING e os cálculos foram executados por meio do módulo de programação do SPRING, denominado LEGAL. A área de estudo foi o Estado do Paraná e as estimativas foram geradas, ao nível municipal, para os anos safra de 1996/97, 1997/98 e 1998/99. Mosaicos quinzenais de imagens NOAA-AVHRR, com resolução espacial de 8 x 8 km, transformados em imagens NDVI, foram utilizados como componente espectral no modelo agrometeorológico, visando estimar o índice de área foliar (IAF). O modelo desenvolvido utiliza parâmetros agronômicos e meteorológicos para cálculo da produtividade máxima ou potencial. Esta produtividade é então penalizada quando a demanda hídrica da cultura não é suprida adequadamente, gerando a produtividade real estimada. A análise da comparação desta estimativa com os valores de produtividade divulgados pela Secretaria de Agricultura e Abastecimento do Paraná (SEAB), ao nível municipal, foi feita através do teste "t" para pares de observação, e o resultado para cada ano safra foi: a)em 1996/97 o modelo subestimou a produtividade em relação à estimativa da SEAB em 59kg/ha (t=-2,91; alfa<0,05); b)em 1997/98 a estimativa do modelo e da SEAB não apresentaram diferença significativa (t=1,46; alfa>0,05); e em 1998/99 o modelo superestimou a produtividade em 192kg/ha (t=7,59; alfa<0,05). Isso demonstra que o modelo foi bastante satisfatório na estimativa da produtividade de soja e requer apenas pequenos ajustes. Através do índice de penalização, gerado quinzenalmente pelo modelo, foi possível fazer o acompanhamento das condições de crescimento e desenvolvimento da cultura da soja, detectando-se deficiências hídricas relevantes ao longo da estação de crescimento em cada ano safra. O aplicativo SPRING e seu módulo LEGAL foram satisfatórios na integração do modelo e na realização dos cálculos de produtividade da soja. As imagens NOAA-AVHRR não se mostraram satisfatórias para estimar o IAF, de tal forma que se utilizou dados da literatura para estimar este parâmetro dentro do cálculo da produtividade.
The objective of the present work was to develop a model to monitor and estimate soybean (Glycine max L. Merril)crop yield in a geographic information system (GIS)based on a punctual agrometeorological model and NOAA/AVHRR images. The integration of the model and the database was performed using the SPRING software and calculations were executed through the SPRING module denominated LEGAL. The study area is the Paraná State and estimates were generated at the municipality level, for the crop years of 1996/97, 1997/98 and 1998/99. Mosaics of 15 days NOAA/AVHRR images, with spatial resolution of 8 x 8km, transformed into NDVI images, were used as the spectral component of the agrometeorological model in order to estimate the leaf area index (LAI). The developed model uses agronomic and meteorological parameters to calculate maximum or potential yield. Whenever the crop water demand is not adequately supplied this yield is penalized and actual yield is estimated. Comparative analysis between the yield estimated by the model and the yield provided by the Secretaria de Agricultura e Abastecimento do Paraná (SEAB), at the municipality level, was performed using the paired comparison t test and the results for each crop year were as follow: a)in 1996/97 the model underestimated the yield in relation to the SEAB estimate by 59 kg.ha$^{-1}$ (t=-2.91; a<0.05); in 1997/98 yield estimate of both model and SEAB were not significantly different from each other (t=1.46; a>0.05); and, in 1998/99 the model overestimated yield by 192 kg.ha$^{-1}$ (t=7.59; a<0.05). This demonstrates that the model estimated quite satisfactory the soybean yield and requires only minor adjustments. Through the penalization index, generated every 15 days, it was possible to monitor soybean crop grow and development conditions detecting relevant water deficits over the crop growing season in each year. The SPRING software and its LEGAL module performed satisfactory in both model integration and soybean yield calculations. The NOAA/AVHRR images did not performed satisfactory in the LAI estimation and, therefore, data from the literature were alternatively used to estimate this parameter in yield calculation.

Através da avaliação do impacto das teorias de governo das sociedades nas empresas cotadas em Portugal e do seu desenvolvimento em Portugal, esta dissertação ajuda a compreender como a performance das empresas cotadas em Portugal se relaciona com as variáveis de governo das sociedades. Este estudo baseia-se numa amostra de 38 empresas Portuguesas entre os anos 2005 e 2012. As principais conclusões são que percentagens mais elevadas de independência nos conselhos de administração evidenciam maiores níveis de performance, e que a dualidade de funções de CEO e Chairman demonstra benefícios na performance das empresas. Também verificámos que o modelo Latino têm vindo a perder observações para o modelo Anglo-Saxónico, e adicionalmente, verificámos que a maioria das empresas cotadas em Portugal são controladas por famílias.
Through the evaluation of the impact of corporate governance theories on Portuguese Listed Companies and its development on Portugal, this dissertation helps to understand how does performance in Portuguese listed companies relates to Corporate Governance variables. This study, is based on a sample of 38 Portuguese firms, during the period of 2005 to 2012. The main conclusions are the higher levels of board independence that evidenced higher levels of performance, and the CEO and Chairman role duality showed benefits on companies' performance. Also, the Latin model systems have been losing observations to the Anglo-Saxon model, additionally, statistically the majority of Portuguese Listed companies are controlled by families.

Abstract:

Traditional financial theories see capital structure as a result of mainly financial, tax and growth factors (Modigliani & Miller, 1958). But corporate governance theories (Jensen & Meckling, 1976) and business strategy theories (Barton & Gordon, 1988) suggest that ownership structure and ownership concentration, product diversification and asset specificity may also influence capital structure. Focusing on the examination of the determinants of capital structure in Chinese listed companies, this research goes beyond financial factors and considered business strategy and corporate governance approaches, and their impact on capital structure, in a transitioning Chinese context where institutions, expertise and regulatory processes are different to, but converging on, Western approaches. A panel data set of 1,098 Chinese listed companies for the period of 1991 to 2000 was collected from published sources, and conventional and innovative econometric methodologies were used to model a range of relationships between capital structure and its financial and non-financial determinants. The statistical approaches used in this study included Ordinary Least Squares Model and also Linear Mixed Model, which is a powerful tool to examine panel data where independence of explanatory variables is not assumed. The analysis also involved Hox’s model building procedures to measure model fit. The capital structure of listed companies in both the Shenzhen Stock Exchange and the Shanghai Securities Exchange is positively related to a firm’s tax rate, growth and capital intensity and negatively related to a firm’s profit and size. Other financial factors such as tangibility, risk and duration are non-significant. The capital structure of listed companies, particularly in the Shenzhen Stock Exchange, is positively related to product diversification and negatively related to asset specificity. The capital structure of listed companies in the Shanghai Securities Exchange is positively related to government ownership and ownership concentration of the largest shareholder and negatively related to legal person ownership and ownership concentration of the ten largest shareholders. The data and modelling support financial and non-financial determinants of capital structure. In particular, information asymmetry, business diversity and asset specificity have a significant impact on capital structure. In addition the empirical work in the study supports agency cost explanations of debt and equity. Finally the research demonstrates that the two main financial markets in China, Shenzhen and Shanghai, have operated differently but are converging towards a common norm. The research contributes to the general field of capital structure and provides valuable insights into the nature of the Chinese firm and the evolution of the Chinese financial system.

This work addresses issues related to analysis and development of multivariable predictive controllers based on bilinear multi-models. Linear Generalized Predictive Control (GPC) monovariable and multivariable is shown, and highlighted its properties, key features and applications in industry. Bilinear GPC, the basis for the development of this thesis, is presented by the time-step quasilinearization approach. Some results are presented using this controller in order to show its best performance when compared to linear GPC, since the bilinear models represent better the dynamics of certain processes. Time-step quasilinearization, due to the fact that it is an approximation, causes a prediction error, which limits the performance of this controller when prediction horizon increases. Due to its prediction error, Bilinear GPC with iterative compensation is shown in order to minimize this error, seeking a better performance than the classic Bilinear GPC. Results of iterative compensation algorithm are shown. The use of multi-model is discussed in this thesis, in order to correct the deficiency of controllers based on single model, when they are applied in cases with large operation ranges. Methods of measuring the distance between models, also called metrics, are the main contribution of this thesis. Several application results in simulated distillation columns, which are close enough to actual behaviour of them, are made, and the results have shown satisfactory
Este trabalho aborda aspectos relacionados ? an?lise e ao desenvolvimento de controladores preditivos multivari?veis baseados em multi-modelos bilineares. O Controlador Preditivo Generalizado (GPC) Monovari?vel e Multivari?vel para o caso linear ? apresentado, sendo destacadas suas propriedades, caracter?sticas principais e aplica??es na ind?stria. O GPC bilinear, que ? o controlador base de todo o desenvolvimento desta Tese, ? apresentado atrav?s da abordagem da quasilineariza??o por degrau de tempo. Alguns resultados empregando este controlador s?o apresentados de forma a evidenciar o melhor desempenho do mesmo, quando comparado ao GPC linear, visto que os modelos bilineares representam melhor a din?mica de determinados processos. A quasilineariza??o por degrau de tempo, devido ao fato de ser uma aproxima??o, provoca um erro de predi??o, que limita o desempenho deste controlador ? medida que seu horizonte de predi??o aumenta. Devido ao referido erro de predi??o, o GPC bilinear com compensa??o iterativa ? mostrado de forma a minimizar o referido erro, buscando um melhor desempenho que o GPC bilinear cl?ssico. Alguns resultados utilizando o algoritmo de compensa??o iterativa s?o mostrados. O emprego dos multi-modelos ? abordado nesta Tese, buscando suprir a defici?ncia existente em controladores baseados em modelo ?nico, quando os mesmos s?o aplicados em processos com grandes faixas de opera??o. Formas de mensura??o de dist?ncia entre modelos, tamb?m chamadas de m?tricas, consistem na principal contribui??o desta Tese. Diversos resultados de aplica??o em colunas de destila??o simuladas, que se aproximam bastante do comportamento real das mesmas, foram realizados, e os resultados se mostraram satisfat?rios

Abstract:

La prédominance de l’informel dans l’économie d’Haïti, où plus de 80% de la population vit en dessous du seuil de la pauvreté et plus de 35% au chômage, laisse entrevoir des liens étroits entre l’économie informelle, la pauvreté et le marché du travail. Faire ressortir ces interrelations, exige une évaluation de cette économie informelle qui fait l’objet des quatre chapitres de notre thèse traitant successivement l’évolution de la situation macroéconomique, le capital humain, les gains des travailleurs informels, et la segmentation du marché du travail.Le premier chapitre fait un diagnostic du phénomène selon l’état des lieux des théories élaborées et l’évolution du cadre macro-économique d’Haïti de 1980 à 2010 et propose une évaluation macroéconomique de l’informel à partir d’un modèle PLS (Partial Least Squares) en pourcentage du PIB.Le chapitre deux établit les relations entre l’évolution de l’économie informelle, dérégulation et politiques néolibérales grâce à un modèle LISREL (Linear Structural Relations). Nous examinons les incidences des politiques fiscales, budgétaires et monétaires des 30 dernières années sur l’économie informelle. Nous réévaluons aussi les causes de l’évolution de l’informel généralement évoquées par les études empiriques (taxes, sécurité sociale).Au chapitre trois, nous analysons la dimension micro-réelle de l’informel grâce à un modèle des gains à la Mincer estimé par les équations logit à partir des données d’une enquête nationale sur l’emploi et l’économie informelle (EEEI) de 2007. Nous analysons les déterminants des gains informels au regard de la position des travailleurs sur le marché (salariés, entrepreneurs et indépendants) ; et les revenus (formels et informels) et les caractéristiques socioéconomiques des travailleurs pauvres et non-pauvres par rapport au seuil de pauvreté.Au chapitre quatre, nous testons d’abord la compétitivité et la segmentation du marché de l’emploi en faisant usage de modèle de Roy et du modèle de Roy élargi à travers une estimation d’un modèle Tobit. Nous utilisons un modèle de Processus de Dirichlet : d’abord analyser la segmentation et la compétitivité éventuelle du marché du travail informel ainsi que ses déterminants, selon les données de l’EEEI-2007 ; ensuite, pour distinguer les caractéristiques fondamentales des informels involontaires (exclus du marché du travail formel) de celles des informels volontaires qui en retirent des avantages comparatifs
The predominance of the informal sector in the economy of Haiti, where more than 80% of the population lives below the threshold of poverty and more than 35% unemployed, suggests links between the informal economy, poverty and the labour market. Highlight these interrelationships, requires an assessment of the informal economy, which is the subject of the four chapters of this thesis, dealing successively with the evolution of the macroeconomic situation, human capital, the informal earnings of workers, and the segmentation of the labour market.The first chapter made a diagnosis of the phenomenon according to the State of affairs of the developed theories and the evolution of the macroeconomic framework of Haiti from 1980 to 2010. And then offers a macroeconomic assessment of the informal sector as a percentage of GDP from a PLS (Partial Least Squares).Chapter two sets out the relationship between the evolution of the informal economy, deregulation and neo-liberal policies through a LISREL (Linear Structural Relations) model. We look at the impact of the budgetary, fiscal and monetary policies of the past 30 years on the informal economy. We also reassess the causes of the evolution of the informal economy generally evoked by the empirical studies (taxes, social security).In the chapter three, we analyse the micro-real dimension of the informal economy through a model of the Mincer earnings estimated by the equations logit from data in a national survey on employment and the informal economy (EEEI) in 2007. We analyse the determinants of informal gains in terms of the position of the market workers (employees, entrepreneurs and self-employed); and revenues (formal and informal) and the socio-economic characteristics of the working poor and non-poor compared to the poverty line.In chapter four, we first test the competitiveness and the segmentation of the labour market by making use of model of Roy and the expanded Roy model through an estimate a model Tobit. We use a model of Dirichlet process: first analyse the segmentation and possible informal work and market competitiveness as its determinants, according to data from the EEEI 2007; then, to distinguish the fundamental characteristics of the involuntary informal (excluded from the formal labour market) than the voluntary informal who gain comparative advantages

Abstract:

O presente trabalho assenta na temática da manipulação de resultados contabilísticos. Analisa-se o conceito de manipulação de resultados, identificam-se os tipos de incentivos que levam os gestores a manipular os resultados e identificam-se as diferentes práticas de manipulação de resultados. O principal objetivo da presente dissertação de mestrado consiste em analisar se as empresas cotadas na Bolsa de Valores de Lisboa realizam práticas de manipulação de resultados. Para além desta análise, averigua-se se as empresas de auditoria identificam nos seus relatórios esse tipo de prática. Assim, foram analisadas 34 empresas cotadas nos anos de 2011 a 2014 e foi utilizado o Modelo de Beneish com cinco variáveis para identificar se as empresas realizam práticas de manipulação de resultados. As conclusões obtidas revelam que as empresas cotadas portuguesas não manipularam a sua informação financeira, no período em análise, e os relatórios de auditoria, apesar de revelarem factos importantes que ajudam a clarificar as demonstrações financeiras das empresas, não identificam este tipo de práticas; Abstract: Earning management: Application of the Beneish model to Portuguese listed companies (2011-2014) The present work is based on the earnings management thematic. We analyse the concept of earnings management; identify the incentives that lead managers to manipulate results as well as the different practices of manipulation. The main objective of this dissertation is to analyse if the companies listed on the Euronext Lisbon perform results manipulation practices and find out if audit firms identify this type of practice in their reports. Were analysed 34 companies in the timeline between the years 2011 to 2014 and it was used the Beneish Model with five variables that allows us to identify if the companies perform practices of manipulation of results or even if they are more predisposed to the accomplishment of these same practices. The conclusions reached show that Portuguese listed companies do not manipulate their financial information, in the period under review and the audit reports, despite revealing important facts that help to clarify the financial statements of companies, do not identify such practices.

Abstract:

It is well recognised that construction firms encounter risk and are sensitive to trends and volatility in the business environment. Measuring the financial performance of a firm serves as the basis of monitoring and evaluating its management competence, resource allocation and corporate strategy in response to environmental change. Forecasting is paramount in responding to potential problems and perpetuating positive developments that result in sustainable competitiveness. Thus, an enriched understanding and prediction of the financial performance of construction firms are desirable for decision makers and other industry stakeholders. Notwithstanding that, little research attention has been paid to this premise conceptually and empirically. Thus, the overall aim of this study was to model and forecast the general financial performance of Hong Kong construction firms under the dynamic influence of the business environment. This study involved the application of quantitative modelling using various statistical and econometric techniques. Multidimensional firm financial performance was first approximated using factor analysis based on the financial data of local publicly listed construction firms from 1992 to 2010. The factor model uncovers five common financial factors: liquidity, asset, leverage, profitability and activity. The time trends of these factors display diverse and cyclical patterns with irregular cycle periods. Autoregressive integrated moving average (ARIMA) models were then constructed based on the Box-Jenkins approach, which provided univariate forecasts of the financial factors. The results reaffirmed that ARIMA models were highly effective in forecasting. In conjunction with cross-correlation analysis, multiple linear regression (MLR) models were next used to explore the influence of environmental determinants on firm financial performance. The findings identified different sets of significant leading determinants for different financial factors. They further justified the dominance of sectoral factors in the determination of firm performance. Supported by empirical verification, a theoretical framework depicting the relationships between business environment and firm performance was proposed.

This study is among the first to apply advanced econometric techniques to develop reliable performance measurement and forecasting models. The results improve the theoretical framework by explaining the dynamic relationships between the financial performance and business environment of construction firms. The empirical findings of the quantitative analysis offer new implications for firms’ financial performance and the significant leading determinants in a local context. The outcomes of this study make seminal contributions to current knowledge and practice.

ENGLISH ABSTRACT: The practice of combining single-factor multiples (SFMs) into composite multiples models is underpinned by the theory that various SFMs carry incremental information, which, if encapsulated in a superior value estimate, largely eliminates biases and errors in individual estimates. Consequently, the chief objective of this study was to establish whether combining single value estimates into an aggregate estimate will provide a superior value estimate vis-á-vis single value estimates. It is envisaged that this dissertation will provide a South African perspective, as an emerging market, to composite multiples modelling and the multiples-based equity valuation theory on which it is based. To this end, the study included 16 SFMs, based on value drivers representing all of the major value driver categories, namely earnings, assets, dividends, revenue and cash flows. The validation of the research hypothesis hinged on the results obtained from the initial cross-sectional empirical investigation into the factors that complicate the traditional multiples valuation approach. The main findings from the initial analysis, which subsequently directed the construction of the composite multiples models, were the following: Firstly, the evidence suggested that, when constructing multiples, multiples whose peer groups are based on a combination of valuation fundamentals perform more accurate valuations than multiples whose peer groups are based on industry classifications. Secondly, the research results confirmed that equity-based multiples produce more accurate valuations than entity-based multiples. Thirdly, the research findings suggested that multiples models that are constructed on earnings-based value drivers, especially HE, offer higher degrees of valuation accuracy compared to multiples models that are constructed on dividend-, asset-, revenue- or cash flowbased value drivers. The results from the initial cross-sectional analysis were also subjected to an industry analysis, which both confirmed and contradicted the initial cross-sectional-based evidence. The industry-based research findings suggested that both the choice of optimal Peer Group Variable (PGV) and the choice of optimal value driver are industry-specific. As with the initial cross-sectional analysis, earnings-based value drivers dominated the top positions in all 28 sectors that were investigated, while HE was again confirmed as the most accurate individual driver. However, the superior valuation performance of multiples whose peer groups are based on a combination of valuation fundamentals, as deduced from the crosssectional analysis conducted earlier, did not hold when subjected to an industry analysis, suggesting that peer group selection methods are industry-specific. From this evidence, it was possible to construct optimal industry-specific SFMs models, which could then be compared to industry-specific composite models. The evidence suggested that composite-based modelling offered, on annual average, between 20.21% and 44.59% more accurate valuations than optimal SFMs modelling over the period 2001 to 2010. The research results suggest that equity-based composite modelling may offer substantial gains in precision over SFMs modelling. These gains are, however, industry-specific and a carte blanche application thereof is ill advised. Therefore, since investment practitioners’ reports typically include various multiples, it seems prudent to consider the inclusion of composite models as a more accurate alternative.
AFRIKAANSE OPSOMMING: Die praktyk om Enkelfaktor Veelvoude (EFVe) te kombineer in saamgestelde veelvoudmodelle word ondersteun deur die teorie dat verskillende EFVe oor inkrementele inligting beskik, wat, indien dit in ’n superieure waardeskatting opgeneem word, grootliks vooroordele en foute in individuele skattings elimineer. Gevolglik was die hoofdoel van hierdie studie om vas te stel of die kombinering van verskeie enkelfaktor waardeskattings in ’n totale waardeskatting ’n superieure waardeskatting sal verskaf vis-á-vis enkelfaktor waardeskattings. Dit word voorsien dat hierdie proefskrif ’n Suid-Afrikaanse perspektief, as ’n ontluikende mark, sal bied aangaande saamgestelde veelvoudmodellering en die veelvoud-gebaseerde ekwiteitswaardasie-teorie waarop dit gebaseer is. Hiermee ten doel, sluit hierdie studie 16 EFVe in, gebaseer op waardedrywers wat al die vernaamste waardedrywerkategorieë, naamlik verdienste, bates, dividende, omset en kontantvloeie, verteenwoordig. Die bevestiging van die navorsingshipotese is afhanklik van die resultate soos bekom vanuit die aanvanklike dwarsdeursnee-empiriese ondersoek na die faktore wat die tradisionele veelvoudwaardasieproses kompliseer. Die hoofbevindinge van die aanvanklike ontleding, wat daarna rigtinggewend was vir die komposisie van die saamgestelde veelvoudmodelle, was die volgende: Eerstens, dui die bewyse daarop dat, wanneer veelvoude saamgestel word, veelvoude waarvan die portuurgroepe op ’n kombinasie van fundamentele waardasieveranderlikes gebaseer is, meer akkurate waardasies lewer as veelvoude waarvan die portuurgroepe op industrie-klassifikasies gebaseer is. Tweedens, het die navorsingsresultate bevestig dat ekwiteitsgebaseerde veelvoude meer akkurate waardasies lewer as entiteitsgebaseerde veelvoude. Derdens, toon die navorsingsbevindinge dat veelvoudmodelle wat saamgestel word uit verdienstegebaseerde waardedrywers, veral wesensverdienste (WV), hoër grade van waardasie-akkuraatheid bied in vergelyking met veelvoudmodelle wat saamgestel word uit dividend-, bate-, omset- of kontantvloei-gebaseerde waardedrywers. Die resultate van die aanvanklike dwarsdeursnee-ontleding is ook onderwerp aan ’n industrie-ontleding, wat die aanvanklike bevindinge van die dwarsdeursnee-ontleding beide bevestig en weerspreek het. Die bevindinge vanaf die industrie-ontleding dui daarop dat beide die keuse van optimale Portuurgroepveranderlike (PGV) en die optimale keuse van waardedrywer, industrie-spesifiek is. Soos met die aanvanklike dwarsdeursnee-ontleding, het verdienste-gebaseerde waardedrywers die top posisies by al 28 sektore wat ondersoek is, gedomineer, terwyl WV weer as die akkuraatste individuele waardedrywer bevestig is. Die superieure waardasie-resultate van veelvoude waarvan die portuurgroepe gebaseer was op ’n kombinasie van fundamentele waardasie-veranderlikes, soos afgelei uit die aanvanklike dwarsdeursnee-ontleding, het egter nie dieselfde resultate gelewer op ’n per sektor basis nie, wat aandui dat portuurgroep seleksiemetodes industrie-spesifiek is. Vanuit hierdie bevindinge was dit moontlik om optimale EFV-modelle saam te stel, wat dan vergelyk kon word met industrie-spesifieke saamgestelde veelvoudmodelle. Die bevindinge het voorgestel dat saamgestelde modellering gemiddeld jaarliks, tussen 20.21% en 44.59% meer akkurate waardasies gelewer het as optimale EFVmodellering oor die tydperk 2001 tot 2010. Die navorsingsresultate dui aan dat ekwiteitsgebaseerde saamgestelde modellering aansienlike toenames in waardasie-akkuraatheid mag bewerkstellig bo dié van EFVmodellering. Hierdie toenames is egter industrie-spesifiek en ’n carte blanche toepassing daarvan is nie aan te beveel nie. Gevolglik, aangesien beleggingspraktisyns se verslae tipies verskeie veelvoude insluit, blyk dit redelik om die insluiting van saamgestelde modelle as ’n meer akkurate alternatief te oorweeg.

Institutions of higher learning (IHL) in Brazil have suffered from idleness in classroom courses, mainly due to the higher number of places offered in the last ten years. Many IHL consider the distance education, and regionalization strategy that this method enables, a way to maintain or increase their margins. However, the development and operation of these courses require expertise not normally found in traditional classroom structure of institutions. Thus, most managers of IHL find some difficulty in financial planning of the distance education project and its feasibility analysis, this occurs because of the complexity and the amount of variables that impact the definition of income and all expenses, including items from tutors to reviewers, editors, cameramen etc. In this context, this study presents a complete breakdown of the variables that influence the financial outcomes of a distance learning course. The assumptions of the variables are divided into five groups: Organizational Management, Content Development, Information Technology, Mentoring and Market, and its valuation distributed among income, investments and costing. Further it also performed simulations and analysis of financial results to a better practical understanding of the model

O Turismo configura-se como uma atividade que apresenta constante movimento podendo impulsionar o desenvolvimento local nas esferas econ?mica, sociocultural e humana em localidades com potencial e estrutura??o para tal. Por ser uma atividade din?mica, o turismo permite mudan?as em seu fluxo, ampliando os per?odos de sazonalidade. Para tanto, tendo em vista a dinamicidade citada, torna-se relevante a presen?a do planejamento tur?stico, inicialmente partindo do poder p?blico para que este crie leis e elabore normas e projetos para a gest?o da atividade de forma ordenada, visando a participa??o cidad?, tornando imprescind?vel a presen?a dos atores e agentes do turismo local no processo, ampliando a democracia e o conhecimento de seu lugar de origem. Neste cen?rio, o Minist?rio do Turismo desponta com o Plano Nacional de turismo que incorpora entre suas a??es o Programa de Regionaliza??o do Turismo, adotando um modelo de gest?o regional local, de forma participativa, atrav?s das inst?ncias de governan?a institu?das nos polos, sendo as a??es da pol?tica p?blica em suas diferentes inst?ncias os maiores respons?veis pelo fomento do turismo no polo Serid?. O presente trabalho cient?fico se prop?e a analisar o polo Serid?, sob a teoria do Ciclo de Vida de ?reas Tur?sticas (TALC) proposta por BUTLER (1980), localizando as a??es voltadas para o turismo e a cronologia da atividade aplicada ? localidade no processo proposto. Para tanto a metodologia utilizada foi a descritivo-explorat?ria, de abordagem qualitativa, de n?vel hist?rico e narrativo, de amostragem n?o-probabil?stica, utilizando fontes secund?rias, atrav?s de documentos e demais registros ocorridos durante os processos de planejamento na regi?o, assim como fontes prim?rias, atrav?s de entrevista estruturada aplicada ? gestora p?blica do PNMT e PRT no Estado do RN, no intuito de ter acesso ?s informa??es relacionadas ao processo de planejamento da atividade tur?stica no Serid?. Utilizou-se como forma de investiga??o dos dados coletados a t?cnica de an?lise do conte?do. Como conclus?o deste estudo observa-se que a partir do levantamento feito em rela??o ao hist?rico do turismo na regi?o que as atividades econ?micas da pecu?ria, cotonicultura, minera??o e ind?stria ceramista foram respons?veis pela inicia??o do turismo na localidade atrav?s do fluxo direcionado ?s mesmas, da inser??o dos primeiros hot?is e da realiza??o de eventos tradicionais, dando margem ? demanda por pol?ticas p?blicas que auxiliassem no direcionamento da atividade estando por isso, inserida na fase de envolvimento, segunda fase do modelo proposto por Buttler (1980), sendo o estudo finalizado com sugest?es para a continuidade da atividade tur?stica na regi?o.
Tourism is configured as an activity that presents constant movement could boost local development in the economic, sociocultural and human in locations with potential for structuring and such. Because it is a dynamic activity, tourism allows changes in its flow, extending the periods of seasonality. To this end, in view of the aforementioned dynamics, it becomes relevant to the presence of tourism planning, initially starting from the government so that it create laws and standards and develop projects for the management of activities in an orderly way, seeking citizen participation, making essential the presence of actors and agents in local tourism, expanding democracy and knowledge of their place of origin. In this scenario, the Ministry of Tourism is emerging with the National Tourism Plan which incorporates among its actions, the Regionalization Program Guide, adopting a model of regional local management, a participatory manner, through the bodies of governance imposed at the poles, and the shares of public policy in their various departments most responsible for promoting tourism in pole Serid?. This scientific work aims to analyze the pole Serid?, under the theory of tourism area life cycle (TALC) proposed by BUTLER (1980), locating actions for tourism and chronology of the locality applied the proposed process activity. For both the methodology is descriptive and exploratory, qualitative approach, historical, descriptive and narrative level, non-probability sampling, using secondary sources, through documents and other records occurred during the planning processes in the region, in order to have access to information related to the planning process of tourism in Serid?, using as a way to research the data collected the technique of content analysis. As a conclusion of this study it is observed that from the survey in relation to the history of tourism in the region, economic activities of livestock, cotton industry, mining and ceramics industry were responsible for the initiation of tourism in the locality through the flow directed to the same, the insertion of the first hotels and performing traditional events, giving rise to the demand for public policies that aided in directing the activity being, therefore, inserted into the engagement phase, the second phase proposed by BUTLER (1980) model, and the study was terminated with suggestions for the continuation of tourism in the region.

The main objective of this work is to analyze the more evident competitive advantages due to the adoption of the production model called Modular Consortium. Therefore, it will be analyzed two truck and bus manufacturers, of the Brazilian, that adopted two different production process. Volkswagen Truck and Bus Modular Consortium, located in Resende city (RJ) has a revolutionary manufacture process, that the main company delegates the assemblies tasks, logistics and a portion of the product development to the 7 main suppliers. Each module manages its own workers, and just some specific department (engineering, quality assurance, marketing, sales and assistance) has Volkswagen employees. In the other hand, the A manufacturer has a vertical production process; it means that the main vehicle s component are made, and developed, by its own manufacture plant. The methodology used was based on non structured interviews with personal from the Human Resource / Logistics / Product Engineering Departments. The basic characteristic to delegate tasks, the Modular Consortium, optimizes the utilization of its employees. This factor, if analyzed by the Brazilian side, could be considered a negative point, due to its high level of unemployment. But this optimization could be related as an efficiency indicator of the Volkswagen Truck and Bus Modular Consortium. The fact that the Modular Consortium concept permits the main company to delegate secondary tasks allows it to concentrate in strategic areas like its mark and its market performance.
O objetivo geral neste trabalho ? analisar as vantagens competitivas, mais latentes, geradas pelo modelo de produ??o denominada cons?rcio modular. Para tanto ser?o analisadas duas montadoras, de ve?culos comerciais, que det?m diferentes processos produtivos mencionados. O cons?rcio modular Volkswagen Caminh?es e ?nibus, situada na cidade de Resende (RJ) possui um processo de produ??o inovador, na qual a empresa contratante delega as tarefas de montagem, log?stica de suprimentos e parte do desenvolvimento do produto para 07 fornecedores. Cada m?dulo administra seus funcion?rios, sendo que apenas departamentos muito espec?ficos (engenharia do produto, garantia de processo e da qualidade, marketing, vendas e assist?ncia t?cnica) possuem funcion?rios diretamente ligados ? Volkswagen. Em contrapartida a Empresa A possui uma produ??o totalmente verticalizada, onde os principais componentes dos ve?culos s?o fabricados, e desenvolvidos, pela pr?pria montadora. A metodologia da pesquisa de campo baseou-se em entrevistas n?o-estruturadas com os profissionais dos Departamentos de Recursos Humanos, Log?stica e Engenharia do Produto. Devido a caracter?stica b?sica em delegar tarefas, o Cons?rcio Modular, otimiza a utiliza??o de funcion?rios para a produ??o / desenvolvimento de seus ve?culos. Esse fator se analisado sob a ?tica brasileira pode ser considerado mal?fico, devido ? alta taxa de desemprego do pa?s. Todavia essa otimiza??o traduz-se como um indicador de efici?ncia do Cons?rcio Modular Volkswagen Caminh?es e ?nibus. Em ?ltima an?lise o fato do conceito de cons?rcio modular permitir a empresa em delegar tarefas ditas como secund?rias propicia a mesma concentrar-se em ?reas estrat?gicas como sua marca e seu desempenho no mercado consumidor.

A crioterapia com nitrog?nio l?quido tem sido terapeuticamente utilizada em diferentes tipos de tecidos. Entretanto, ainda n?o h? registros na literatura referentes ? sua utiliza??o em canais radiculares. Assim, o objetivo deste trabalho foi elaborar um modelo experimental in vitro para conhecer o comportamento dos tecidos dent?rios na condu??o de temperatura com aplica??o de nitrog?nio l?quido intracanal e estabelecer um protocolo para a sua aplica??o. Termopares fixos ? superf?cie externa radicular nas regi?es apical, m?dia, cervical e no interior do canal foram utilizados como sensores para medidas das varia??es de temperaturas em um dente mantido em banho de calibra??o t?rmica. O agente crioter?pico utilizado foi nitrog?nio l?quido em sistema aberto na forma de spray intracanal na regi?o apical. Os sinais foram digitalizados e analisados em um software. Foram realizados 13 testes com 15 segundos de aplica??o divididos em 3 grupos conforme temperatura ambiente: 20?C, 25 ?C e 27 ?C. As m?dias de temperatura obtidas foram: intracanal, regi?o apical -45,23?C, superf?cie externa radicula r, regi?o apical -19,77?C, regi?o m?dia -17,46?C e regi?o cervical 4,15?C. Concluiu-se que o modelo experimental permite conhecer a condutividade das estruturas dent?rias quando aplicado um agente crioter?pico no interior do canal radicular. Tamb?m se verificou que a aplica??o de nitrog?nio l?quido por 15 segundos no modelo proposto atinge temperaturas capazes de causar morte celular em estruturas de sustenta??o dent?ria localizadas pr?ximas ao ?pice radicular

Companies need to review their Business Models (BM) over time to remain competitive. Technological changes and outsourcing have made the market even more dynamic, requiring organizations to reinvent themselves and innovate. Business Model analysis allows companies to reflect about their current configurations, compare it with those adopted by competitors, innovate and instantiate future BMs. The Activity System (AS) perspective is an inter-relational array of activities that together build a Value Proposition. The literature review shows the absence of a systemic method for BM analysis. Therefore, the purpose of this paper is to provide a method for BM analysis in AS perspective. Design Science Research was used to propose the method through the analysis of four companies, from two different sectors, with different configurations. The proposed method has three pillars: Dimension Analysis, Business Model Representation and Competitiveness Analysis. The main contribution of this research adds to the field of Business Models, through a prescriptive method for analysis using the perspective of the Activity System, relying on empirical research. Furthermore, executives of organizations and consultants can use this method as a pragmatic instrument to deepen their understanding of Business Models, instantiate future models or reinvent them. Moreover, this analysis process has a formative value to organizational strategists, since the strategic review in BM develops its capability of systemic and reflective vision.
As organiza??es precisam revisar seus Modelos de Neg?cio (MN) ao longo do tempo para manter-se competitivas. As mudan?as tecnol?gicas e o processo de terceiriza??o tornaram o mercado competitivo mais din?mico, exigindo que as organiza??es se reinventem e inovem. As an?lises em Modelos de Neg?cio possibilitam refletir sobre a configura??o atual, comparar com aquelas adotadas pela concorr?ncia, instanciar MN futuros e, ainda, inovar. A perspectiva de Sistema de Atividades compreende pelo arranjo de atividades que em conjunto constroem a Proposta de Valor da organiza??o. A revis?o de literatura evidencia a aus?ncia de um m?todo sist?mico para an?lise de MN. Portanto, o objetivo desse trabalho ? propor um m?todo para analisar Modelos de Neg?cio a partir da Perspectiva de Sistema de Atividade. O m?todo Design Science Research foi aplicado para propor o artefato, que contou com a an?lise de quatro empresas, duas duplas de setores distintos, com configura??es diferentes. O m?todo proposto conta com tr?s pilares: o primeiro se refere a An?lise das Dimens?es, o segundo a Representa??o do Modelo de Neg?cios; e o terceiro a An?lise de Competitividade. A principal contribui??o dessa pesquisa ao campo de MN, refere-se ao m?todo prescritivo proposto para an?lise de Modelo de Neg?cio na perspectiva de Sistema de Atividade, com embasamento em pesquisas emp?ricas. Al?m disso, executivos das organiza??es e consultores poder?o utilizar esse m?todo como instrumento para compreender os Modelos de Neg?cio atuais, instanciar modelos futuros ou reinvent?-los. Al?m disso, essa an?lise possui car?ter formativo aos estrategistas, pois a revis?o estrat?gica em Modelo desenvolve sua capacidade de vis?o sist?mica e reflexiva.

This study's objective is to realize a critical analysis of the EVA?? Variable Remuneration Program, beginning from it's theoretical conception and culminating to the definition and critical analysis of the inherent requisites of the analyzed variable remuneration programs in contrast with the identified requisites in the EVA?? Variable Remuneration Program. The EVA?? model shows it's variable remuneration program as a mechanism with the capacity of making managers to think and behave as the company's owners, based on the allegation that the bigger the EVA the bigger the manager's bonus, and the bigger the wealth created to the shareholder. However, this affirmation will be questioned by this dissertation. The research identified that the behavior and the satisfaction of the companies' employers are not just tied to the financial questions, but they are also connected to a variety of elements with the capacity of forming a motivated working environment. It was verified in this dissertation that the EVA?? Variable Remuneration Program partly attends the inherent requisites of the variable remuneration programs
O presente estudo tem o objetivo de realizar a an??lise cr??tica do Programa de Remunera????o Vari??vel EVA??, iniciando por sua concep????o te??rica e culminando na defini????o e an??lise cr??tica dos requisitos inerentes aos programas de remunera????o vari??vel analisados, em contraposi????o aos requisitos identificados no Programa de Remunera????o Vari??vel EVA??. O modelo EVA?? apresenta o seu programa de remunera????o vari??vel como mecanismo capaz de fazer os gestores pensarem e agirem como donos da empresa, sob a alega????o de que quanto maior o EVA, maior o b??nus para o gestor, e maior a riqueza gerada para o acionista. No entanto, esta afirma????o ser?? questionada nesta disserta????o. A pesquisa identificou que o comportamento e a satisfa????o dos funcion??rios de uma empresa n??o est??o relacionados apenas ao car??ter financeiro, e sim a um conjunto de elementos capazes de formar um ambiente de trabalho motivador. Foi verificado nesta disserta????o que o Programa de Remunera????o vari??vel EVA?? atende parcialmente os requisitos inerentes aos programas de remunera????o vari??vel.

RePART (Reward/Punishment ART) is a neural model that constitutes a variation of the Fuzzy Artmap model. This network was proposed in order to minimize the inherent problems in the Artmap-based model, such as the proliferation of categories and misclassification. RePART makes use of additional mechanisms, such as an instance counting parameter, a reward/punishment process and a variable vigilance parameter. The instance counting parameter, for instance, aims to minimize the misclassification problem, which is a consequence of the sensitivity to the noises, frequently presents in Artmap-based models. On the other hand, the use of the variable vigilance parameter tries to smoouth out the category proliferation problem, which is inherent of Artmap-based models, decreasing the complexity of the net. RePART was originally proposed in order to minimize the aforementioned problems and it was shown to have better performance (higer accuracy and lower complexity) than Artmap-based models. This work proposes an investigation of the performance of the RePART model in classifier ensembles. Different sizes, learning strategies and structures will be used in this investigation. As a result of this investigation, it is aimed to define the main advantages and drawbacks of this model, when used as a component in classifier ensembles. This can provide a broader foundation for the use of RePART in other pattern recognition applications
O RePART (Reward/Punishiment ART), modelo neural que se constitui numa varia??o do modelo Fuzzy Artmap, foi proposto objetivando minimizar problemas inerentes aos modelos da classe Artmap, tais como: prolifera??o de categorias e m? classifica??o. Por essa raz?o, o RePART faz uso de mecanismos adicionais, como: um par?metro contador de inst?ncia, um processo de recompensa/puni??o e um par?metro de vigil?ncia vari?vel. O par?metro contador de inst?ncia busca minimizar o problema de m? classifica??o, resultante da sensibilidade ? ru?dos, freq?entemente presente nos modelos da classe Artmap. O uso da vigil?ncia vari?vel tem como objetivo minimizar o problema de prolifera??o de categorias, diminuindo a complexidade da rede, quando utilizado em aplica??es com um grande n?mero de padr?es de treinamento. A proposta do RePART visou a minimiza??o desses problemas e foi mostrado que o RePART obteve desempenho superior que alguns modelos da classe Artmap. Neste trabalho ? proposta a realiza??o de uma investiga??o do desempenho do modelo RePART em comit?s de classificadores. Nesta investiga??o ser? realizada uma an?lise com comit?s utilizando diferentes tamanhos, estrat?gias de aprendizados e estruturas. Os resultados obtidos com esta investiga??o servir?o como meio de descoberta das vantagens e desvantagens de cada um dos modelos abordados em comit?s. Com isso, poder? ser dado um embasamento ainda mais amplo ? utiliza??o do RePART em outras aplica??es de reconhecimento de padr?es

Forecast is the basis for making strategic, tactical and operational business decisions. In financial economics, several techniques have been used to predict the behavior of assets over the past decades.Thus, there are several methods to assist in the task of time series forecasting, however, conventional modeling techniques such as statistical models and those based on theoretical mathematical models have produced unsatisfactory predictions, increasing the number of studies in more advanced methods of prediction. Among these, the Artificial Neural Networks (ANN) are a relatively new and promising method for predicting business that shows a technique that has caused much interest in the financial environment and has been used successfully in a wide variety of financial modeling systems applications, in many cases proving its superiority over the statistical models ARIMA-GARCH. In this context, this study aimed to examine whether the ANNs are a more appropriate method for predicting the behavior of Indices in Capital Markets than the traditional methods of time series analysis. For this purpose we developed an quantitative study, from financial economic indices, and developed two models of RNA-type feedfoward supervised learning, whose structures consisted of 20 data in the input layer, 90 neurons in one hidden layer and one given as the output layer (Ibovespa). These models used backpropagation, an input activation function based on the tangent sigmoid and a linear output function. Since the aim of analyzing the adherence of the Method of Artificial Neural Networks to carry out predictions of the Ibovespa, we chose to perform this analysis by comparing results between this and Time Series Predictive Model GARCH, developing a GARCH model (1.1).Once applied both methods (ANN and GARCH) we conducted the results' analysis by comparing the results of the forecast with the historical data and by studying the forecast errors by the MSE, RMSE, MAE, Standard Deviation, the Theil's U and forecasting encompassing tests. It was found that the models developed by means of ANNs had lower MSE, RMSE and MAE than the GARCH (1,1) model and Theil U test indicated that the three models have smaller errors than those of a na?ve forecast. Although the ANN based on returns have lower precision indicator values than those of ANN based on prices, the forecast encompassing test rejected the hypothesis that this model is better than that, indicating that the ANN models have a similar level of accuracy . It was concluded that for the data series studied the ANN models show a more appropriate Ibovespa forecasting than the traditional models of time series, represented by the GARCH model
Nas organiza??es, a previs?o constitui a base para a tomada de decis?es estrat?gicas, t?ticas e operacionais. Na economia financeira, diversas t?cnicas t?m sido usadas a fim de prever o comportamento de ativos no decorrer das ?ltimas d?cadas. Assim, existem diversos m?todos para auxiliar na tarefa de previs?o de s?ries temporais, entretanto, t?cnicas de modelagem convencionais como modelos estat?sticos e aqueles baseados em modelos matem?ticos te?ricos t?m produzido previs?es insatisfat?rias, aumentando o n?mero de estudos em m?todos mais avan?ados de previs?o. Dentre estes, as Redes Neurais Artificiais (RNA) s?o um m?todo relativamente recente e promissor para a previs?o em neg?cios que se revela uma das t?cnicas que tem causado muito interesse no ambiente financeiro e tem sido utilizado com sucesso em uma ampla variedade de aplica??es de sistemas de modelagem financeiro, provado em muitos casos sua superioridade sobre os modelos estat?sticos ARIMA-GARCH (OLIVEIRA,2007). Nesse contexto, o presente trabalho teve por objetivo analisar se as RNAs s?o um m?todo mais adequado para a previs?o do comportamento de ?ndices em Mercados de Capital do que m?todos tradicionais de an?lise de s?ries temporais. Para tanto, foi desenvolvido um estudo quantitativo que, a partir de ?ndices econ?mico financeiros, elaborou dois modelos de RNA do tipo feedfoward de aprendizado supervisionado, cujas estruturas consistiram em 20 dados na camada de entrada, 90 neur?nios em uma camada oculta e um dado como camada de sa?da (?ndice Ibovespa). Estes modelos utilizaram BackPropagation, fun??o de ativa??o de entrada baseada na tangente Sigmoid e uma fun??o de sa?da linear. Visto o intuito de analisar a ader?ncia do M?todo de Redes Neurais Artificiais ? realiza??o de previs?es do Ibovespa, optou-se por realizar tal an?lise por meio da compara??o de resultados entre este e o M?todo de previs?o em s?ries temporais GARCH, desenvolvendo-se um modelo GARCH (1,1). Uma vez aplicadas ambas as metodologias (RNA e GARCH) e desenvolvidos os modelos, realizou-se a an?lise dos resultados obtidos comparando-se os resultados das previs?es com os dados hist?ricos e estudando-se os erros de previs?o por meio do MSE, RMSE, MAE, Desvio Padr?o, U de Theil e teste abrangente da previs?es. Verificou-se que os modelos desenvolvidos por meio de RNAs apresentaram menores MSE, RMSE e MAE que o modelo de controle e o teste U de Theil indicou que os tr?s modelos estudados apresentam erros menores que os de uma previs?o ing?nua. Embora a RNA baseada em retornos tenha apresentado valores dos indicadores de precis?o inferiores aos da RNA baseada em pre?os, o teste abrangente de regress?es rejeitou a hip?tese de que este modelo seja superior que aquele, indicando que os modelos de RNA apresentam um n?vel semelhante de precis?o. Concluiu-se que, para a s?rie de dados estudada neste trabalho, as Redes Neurais artificiais se mostram um modelo mais adequado de previs?o do que os modelos tradicionais de s?ries temporais, representado neste pelo m?todo GARCH

The purpose of this dissertation is to formulate guidelines for the improvement of maturity models, or the development of new ones, aiming at its application to project departments. The maturity of project management has become critical for organizations that develop projects and want to stand out in the market they serve. For this purpose, maturity models provide paths in order to guarantee that the institutionalization of project management is achieved in the best possible way. Generally, these models assess the organization, define its current situation in managing projects and propose steps to be performed in the search of more advanced levels of maturity. With the objective of contributing to the improvement of maturity models for specific cases, a bibliographical research was conducted for the preparation of a comparative analysis matrix and performed a case study for application of two maturity models (MMGP and PMMM levels 2 and 3), selected based on criteria found in the literature, in an engineering department of an oil company. The case study supported the realization of a comparative analysis of models, from which guidelines were formulated for improvement. The results showed that thedepartment is evaluated in a medium stage of maturity, recording significant progress in some dimensions assessed. They also found that the results of applying the two models are presented as complementary, although the model is highlighted by the greater depth of MMGP diagnostic, considering many variables in their levels of maturity than model PMMM (levels 2 and 3).Finally, directions have been formulated that contribute to the improvement of maturity models, taking in account the organizational environment in which this work was developed
O objetivo da presente disserta??o ? formular diretrizes para o aprimoramento de modelos de maturidade, ou para a elabora??o de novos modelos, visando a sua aplica??o a departamentos de projetos. A maturidade em gerenciamento de projetos tornou-se um fator cr?tico para organiza??es que desenvolvem projetos e querem destacar-se no mercado em que atuam. Para tanto, os modelos de maturidade fornecem caminhos para que a institucionaliza??o da gest?o de projetos seja alcan?ada da melhor maneira poss?vel. Geralmente, esses modelos avaliam a organiza??o, definem sua situa??o atual em gerir projetos e prop?e passos a serem realizados para avan?o do n?vel de maturidade. Visando contribuir para o aperfei?oamento dos modelos de maturidade para casos espec?ficos, formulando diretrizes de aprimoramento, foi realizada uma pesquisa bibliogr?fica para elabora??o de uma matriz de an?lise comparativa e realizado um estudo de caso para aplica??o de dois modelos de maturidade (MMGP e PMMM n?veis 2 e 3), selecionados a partir de crit?rios encontrados na literatura, em um departamento de engenharia de uma empresa do setor de petr?leo. O estudo de caso subsidiou a realiza??o de uma an?lise comparativa dos modelos, a partir da qual foram formuladas diretrizes de aprimoramento. Os resultados mostraram que o departamento avaliado encontra-se num est?gio mediano da maturidade, registrando avan?os significativos em algumas dimens?es avaliadas. Tamb?m foi verificado que os resultados da aplica??o dos dois modelos apresentam-se como complementares, embora destaque-se o modelo MMGP pela maior profundidade de diagn?stico, que leva em conta maior n?mero de vari?veis dentro de seus n?veis de maturidade do que o modelo PMMM (n?veis 2 e 3). Por fim, foram formulados direcionamentos que contribuem para o aprimoramento de modelos de maturidade, considerando o ambiente organizacional em que este trabalho foi desenvolvido

Social impact business are cost effective initiatives that address the needs of lowincome people by providing them with the access to quality products and services at affordable prices, as well as employment and income opportunities. This study aims at contributing to the understanding of this business model that has been getting increasingly more relevant in both the academic and corporate fields. The analysis of the theoretical groundwork indicated that the concept of social impact business does not come from a homogeneous perspective. An analytical framework to identify the elements that constitute the business social impact was proposed based on the characteristics found in the literature review. The methodology applied was of qualitative-quantitative, exploratory nature. As the procedure required for data collection, three steps were followed: a documental analysis using secondary data, interviews and surveys. The results from the data collection allowed us to identify the constituent elements of the business model, mapping existing initiatives in Brazil and describe their characteristics from the proposed framework for analysis, and assess the social impact of these initiatives.

This study aims to analyze the influences that a religious model has on a religious community, stablishing a correlation between Max Scheler?s conception of religious model, ethical progress and religious experience with the bible text Sermon on Mount, specially, the Antitheses (Mt 5, 17-48) and the Lord?s Prayer ritual orientation. With this purpose, in this study is made a research to identify the religious model from Matthew?s community to understand the powerful influence to the construction of the meanings in the social world of this community. This study was possible approaching Max Scheler?s phenomenological works to contextualize the religious model, religious experience and ethical progress concepts. As well as, it was necessary to go deep in historical, social and exegetical aspects from Matthew?s bible text. It was necessary to enable the correlation method associated to the Matthew?s bible text phenomenological analyses to apply Scheler?s horizon to the bible reality, to answer what is the relation between a religious model and religious experience in the community from the Matthew?s bible text.
O presente trabalho tem o prop?sito de analisar as for?as de influ?ncia que o modelo religioso exerce em uma comunidade religiosa. Isso se fundamenta a partir da correla??o estabelecida entre a conceitua??o de modelo religioso, progresso ?tico e experi?ncia religiosa ao mundo social apreendido do texto b?blico o Serm?o da Montanha. A an?lise ter? como objeto a releitura do texto o Serm?o da Montanha, localizado no Evangelho de Mateus, em espec?fico, as Ant?teses (Mt 5.17-48) e a orienta??o ritual?stica do Pai-Nosso (Mt 6.5-15), ? luz do pensamento de Max Scheler. Partindo desse prop?sito, busca-se identificar o modelo religioso da comunidade mateana e compreender a for?a de influ?ncia desse modelo nos significados do mundo social dessa comunidade. O arcabou?o conceitual foi constru?do tendo como base obras do per?odo fenomenol?gico de Max Scheler para contextualiza??o dos conceitos de modelo religioso, progresso ?tico e experi?ncia religiosa. Foi necess?ria a constru??o de uma abordagem cr?tica dos aspectos hist?ricos, sociais e exeg?ticos da per?cope mateana. Por isso, foi poss?vel, a partir do m?todo da correla??o associado ? an?lise fenomenol?gica do Evangelho de Mateus, aplicar o horizonte conceitual scheleriano ? realidade dos vers?culos b?blicos, a fim de responder qual a rela??o entre modelo religioso e experi?ncia religiosa da comunidade mateana.

As organiza??es de um modo geral enfrentam diversas mudan?as, sobretudo em suas estruturas, baseadas em um cen?rio de maior competi??o e de uma necessidade de moderniza??o organizacional. Dentro deste contexto, as pr?ticas de gest?o de projetos recebem maior aten??o e passam a ser adotadas por essas organiza??es, principalmente em rela??o ? gest?o do ciclo de vida do projeto. Dentre as etapas de gerenciamento, o planejamento ? uma das etapas mais relevantes, pois define a linha de base para a execu??o do projeto, al?m de deliberar os procedimentos relativos ao monitoramento e controle das atividades envolvidas. Contudo, em meio ? aus?ncia de uma cultura orientada a projetos e de maior complexidade inerente ao contexto organizacional, observa-se que as pr?ticas tradicionais de planejamento, tais como o Guia PMBOK, apresentam dificuldades de ader?ncia a este novo cen?rio, ao passo que modelos e ferramentas visuais baseadas em telas (canvas) ganham espa?o, ao proporem uma forma mais simples e flex?vel para planejar projetos. Tais modelos tem sua origem na abordagem Lean, vinculada ? gest?o operacional, e assumiram um novo conceito, a partir do modelo Business Model Canvas (BMC), proposto por Osterwalder e Pigneur (2011). Desde ent?o, t?m-se surgido diversos modelos e ferramentas visuais para planejamento, especialmente na ?rea de gest?o de projetos. Um dos modelos criados recentemente ? o Life Cycle Canvas (LCC), desenvolvido por Veras (2016), no qual prop?e a gest?o do ciclo de vida do projeto dentro de uma l?gica de gest?o visual, contemplando as pr?ticas sugeridas pelo Guia PMBOK. No entanto, ainda h? uma car?ncia de estudos que comprovem que modelos visuais baseados em canvas podem ser ?teis ao planejamento de projetos, e que, ao mesmo tempo, contemple as boas pr?ticas sugeridas pelas abordagens tradicionais de gerenciamento. No intuito de comprovar tal rela??o, a presente pesquisa procura analisar em que medida o modelo Life Cycle Canvas (LCC), por meio da gest?o visual, facilita o planejamento de projetos. Para isto, utilizou-se de uma abordagem metodol?gica dedutiva, de natureza quantitativa, por meio de uma survey realizada com 104 profissionais que utilizaram o modelo LCC para planejar projetos, onde foram utilizados a an?lise descritiva, o teste U de Mann-Whitney e a t?cnica de an?lise de regress?o linear m?ltipla para analisar os dados. Os resultados demonstraram que o modelo LCC se mostrou aderente ?s pr?ticas sugeridas pelo Guia PMBOK. Em rela??o ? utiliza??o de ferramentas de apoio ao planejamento de projetos, a pesquisa evidenciou que o grupo de respondentes que utilizou essas ferramentas teve uma percep??o superior em rela??o ao modelo LCC, quando foi comparado ao grupo que n?o utilizou. O estudo ainda observou que quanto mais o modelo LCC torna vis?vel e transparente as informa??es, promove a comunica??o entre os envolvidos e promove a coordena??o do trabalho na elabora??o do projeto, mais ele facilita o planejamento de projetos. Estes resultados refor?am a import?ncia de utilizar estruturas visuais de planejamento na gest?o de projetos, desde que elas contemplem os aspectos relacionados ?s pr?ticas j? reconhecidas neste campo de atua??o e que gerentes de projeto possam estimular esses benef?cios propostos pela gest?o visual.
The organizations generally face several changes, especially in its structures, based on a scenario of increased competition and a need for organizational modernization. Within this context, the project management practices receive more attention and are adopted by these organizations. Planning is one of the most relevant stages of project management, because it defines the baseline for it?s execution, in addition to resolving the procedures for monitoring and control of the activities involved. However, in the absence of a project-oriented culture and of greater complexity inherent in the organizational context, the traditional practices of planning, such as the PMBOK Guide, present difficulties of adherence to this new scenario, while canvas-based models and visual tools gain space, by proposing a simple and flexible way to plan projects. Such models have your origin in Lean approach, linked to the operational management, and assumed a new concept, from the model Business Model Canvas (BMC), proposed by Osterwalder and Pigneur (2011). Since then, several models and visual tools have been developed for planning, especially in the project management area. One of the recently created models is the Life Cycle Canvas (LCC), developed by Veras (2016), in which it proposes the project lifecycle management within a visual management logic, contemplating the practices suggested by the PMBOK guide. However, there is still a dearth of studies that prove that canvas-based visual models can be useful for project planning, and that at the same time contemplating the good practices suggested by traditional management approaches. In order to prove such a relationship, this research seeks to analyze the extent to which the Life Cycle Canvas (LCC) model, through visual management, facilitates project planning. For this, it was used a quantitative methodology deductive approach, by means of a survey conducted with 104 professionals who used the LCC model to plan projects, where the descriptive analysis, the Mann-Whitney U-test and the technique of Multiple linear regression analysis to analyze the data. The results showed that the LCC model adhered to the practices suggested by the PMBOK Guide. In relation to the use of tools to support project planning, the survey showed that the group of respondents who used these tools had a higher perception in relation to the LCC model, when compared to the group that did not utilize. The study also observed that the more the LCC model makes the information visible and transparent, it promotes communication between stakeholders and promotes coordination of work in designing the project, plus it facilitates project planning. These results reinforce the importance of using visual planning structures in project management, provided they contemplate the aspects related to practices already recognised in this field of expertise and that project managers can stimulate these benefits proposed by visual management.

Abstract:

In capital market research (CMR) studies of the value relevance of accounting numbers are founded upon the concept that, in equilibrium, the book values are equal to or have some long-term relationship with the market value and that market returns are related to book returns. This thesis seeks to resolve a gap in the CMR by examining 30 selected individual firms listed on the Australian stock market during the period 1950 to 2004, using equilibrium correction modelling techniques. Even these limited prior works used cross-sectional techniques rather than the long-run, time-series, analysis used in this study. Moreover, dynamic analysis in the CMR has tended to focus on indexes or portfolio data rather than using firm-specific case study data of the type modelled here. No prior research has taken this approach using Australian data. The results of this thesis indicated that an equilibrium correction relationship between market values and book values for firms listed on the Australian Stock Exchange (ASX) could be determined by using accounting and macroeconomic regressors. The findings of the thesis were consistent with the literature in terms of the variables suggested and important in the firm's valuation from the three main approaches, the analysts (industry) approach, the finance and accounting theory (textbook) approach and the CMR literature approach. The earnings, dividends and book value variables are significant in their relationships with the firm's market values. The models constructed were typically more informative and had an increased forecasting performance compared with the a priori models tested, based on theory and the literature.

Abstract:

This study examines the incentives of Australian listed mineral mining companies within the stakeholder theoretical framework to disclose socially responsible information in their corporate annual report. The three dimensions of the stakeholder theory were empirically tested to explain the association of a social disclosure model comprising categories of social disclosure for environment, energy, product and services, human resources and community involvement, with nine firm-specific characteristics. The sample of 179 Australian listed mineral mining companies for the financial year ending 1994 was obtained by personal contact. The extent of social disclosure was measured by a dichotomous index against the social disclosure model. Results of multivariate tests provide evidence that Membership of the Australian Mining Industry Council (Stakeholder Power dimension), and company size (a Control Variable) which was jointly represented by three surrogates (total assets, total sales, and market capitalisation), to be the most significant variables associated with the social disclosure model. The presence of a social responsibility group (Strategic Posture dimension) was also significantly related to the extent of total disclosure and four categories of social disclosure (environment, product and services, human resources, and community involvement). Company age (a Control Variable) was significantly associated with energy related disclosure. Commercial production (a Control Variable) was significant to the total disclosure and two categories of social disclosure (environment, and human resources). Return on equity, and systematic risk (Economic Performance dimension) did not explain social disclosure. The research findings imply that economic performance measures derived from the financial statements of corporate annual reports do not seem to be reliable surrogates for evaluating voluntary social disclosure. To improve the extent of disclosure of socially responsible information, accounting regulators may need to consider issuing an accounting standard on corporate social responsibility disclosure.

An?logas ?s manchas e f?culas fotosf?ricas solares, cuja visibilidade ? modulada por rota??o estelar, as regi?es ativas estelares consistem em grupos de manchas escuras na superf?cie da estrela e f?culas brilhantes causadas pelo seu campo magn?tico. Atualmente, as manchas estelares est?o bem estabelecidas como os principais marcadores usados para estimar o per?odo de rota??o estelar. Por outro lado, o comportamento din?mico das manchas tamb?m pode ser utilizado para analisar outros fen?menos relevantes, tais como a presen?a de atividade magn?tica e os seus ciclos. Para determinar o per?odo de rota??o estelar, identificar a presen?a de regi?es ativas e investigar se a estrela manifesta ou n?o rota??o diferencial, aplicamos dois m?todos: uma an?lise wavelet e um modelo de manchas. O procedimento wavelet tamb?m ? aplicado na an?lise de pulsa??es e na busca por assinaturas espec?ficas para esta variabilidade estelar particular dentre os diferentes tipos de estrelas vari?veis pulsantes. A transformada wavelet tem sido usada como uma ferramenta poderosa para o tratamento de v?rios problemas em astrof?sica. Neste trabalho mostramos que a an?lise em tempo-frequ?ncia das curvas de luz estelares, utilizando a transformada wavelet, ? uma ferramenta pr?tica para a identifica??o de rota??o, atividade magn?tica e assinaturas de pulsa??o. Apresentamos a composi- ??o espectral e as varia??es multiescala das s?ries temporais para quatro classes de estrelas: alvos dominados pela atividade magn?tica, estrelas com planetas, aquelas com tr?nsitos bin?rios, e estrelas pulsantes. Aplicamos a wavelet Morlet de 6 a ordem, que oferece alta resolu??o em tempo e frequ?ncia. Ao aplicar a transformada wavelet no sinal, obtemos os espectros de pot?ncia wavelet local e global. O primeiro ? interpretado como a distribui??o de energia do sinal no espa?o tempo-frequ?ncia, e o segundo ? obtido por integra??o temporal do mapa local. Sendo a transformada wavelet uma ferramenta matem?tica ?til para sinais n?o estacion?rios, esta t?cnica aplicada v ?s curvas de luz, obtidas a partir das miss?es espaciais Kepler e CoRoT, nos permite identificar claramente determinadas assinaturas para diferentes fen?menos. Em particular, foram identificados padr?es para a evolu??o temporal do per?odo de rota??o, bem como uma outra periodicidade decorrente dos efeitos das regi?es ativas nas curvas de luz analisadas; a continuidade de uma determinada escala (frequ?ncia) durante a maior parte do tempo pode representar um indicador de rota??o e atividade. Al?m disso, uma assinatura de padr?o de batimento no mapa wavelet local de estrelas pulsantes ao longo de todo o tempo tamb?m foi detectada. O segundo m?todo ? baseado na detec??o de manchas estelares durante os tr?nsitos de um planeta extrasolar que orbita sua estrela-m?e. Quando um planeta eclipsa sua estrela-m?e ? poss?vel detectar fen?menos f?sicos que ocorrem na superf?cie da estrela. Se uma mancha escura na superf?cie estelar ? eclipsada parcial ou totalmente, a luminosidade estelar integrada aumentar? ligeiramente. A an?lise da curva de luz medida durante um tr?nsito planet?rio nos permite inferir propriedades f?sicas das manchas estelares como o tamanho, a intensidade, a posi??o e a temperatura. Ao detectar a mesma mancha em tr?nsitos consecutivos, ? poss?vel obter informa??es adicionais, como o per?odo de rota??o estelar na latitude do tr?nsito planet?rio, a rota??o diferencial, e os ciclos de atividade magn?tica. Observa??es do tr?nsito planet?rio nas estrelas CoRoT-18 e Kepler-17 foram usadas para aplicar este modelo.
Analogous to sunspots and solar photospheric faculae, which visibility is modulated by stellar rotation, stellar active regions consist of cool spots and bright faculae caused by the magnetic field of the star. Such starspots are now well established as major tracers used to estimate the stellar rotation period, but their dynamic behavior may also be used to analyze other relevant phenomena such as the presence of magnetic activity and its cycles. To calculate the stellar rotation period, identify the presence of active regions and investigate if the star exhibits or not differential rotation, we apply two methods: a wavelet analysis and a spot model. The wavelet procedure is also applied here to study pulsation in order to identify specific signatures of this particular stellar variability for different types of pulsating variable stars. The wavelet transform has been used as a powerful tool for treating several problems in astrophysics. In this work, we show that the time-frequency analysis of stellar light curves using the wavelet transform is a practical tool for identifying rotation, magnetic activity, and pulsation signatures. We present the wavelet spectral composition and multiscale variations of the time series for four classes of stars: targets dominated by magnetic activity, stars with transiting planets, those with binary transits, and pulsating stars. We applied the Morlet wavelet (6th order), which offers high time and frequency resolution. By applying the wavelet transform to the signal, we obtain the wavelet local and global power spectra. The first is interpreted as energy distribution of the signal in time-frequency space, and the second is obtained by time integration of the local map. Since the wavelet transform is a useful mathematical tool for nonstationary signals, this technique applied to Kepler and CoRoT light curves allows us to clearly identify particular signatures for different phenomena. In particular, patterns were identified for the temporal evolution of the rotation period and other periodicity due to active regions affecting these light curves. In addition, a beat-pattern vii signature in the local wavelet map of pulsating stars over the entire time span was also detected. The second method is based on starspots detection during transits of an extrasolar planet orbiting its host star. As a planet eclipses its parent star, we can detect physical phenomena on the surface of the star. If a dark spot on the disk of the star is partially or totally eclipsed, the integrated stellar luminosity will increase slightly. By analyzing the transit light curve it is possible to infer the physical properties of starspots, such as size, intensity, position and temperature. By detecting the same spot on consecutive transits, it is possible to obtain additional information such as the stellar rotation period in the planetary transit latitude, differential rotation, and magnetic activity cycles. Transit observations of CoRoT-18 and Kepler-17 were used to implement this model.

O objetivo principal de estudo ? construir e aplicar um modelo lingu?stico de avalia??o de tesauros, baseado na articula??o entre a An?lise Textual dos Discursos (ATD) e os Estudos sobre G?neros, considerando seu aspecto: hist?rico, textual, discursivo e tipol?gico. A pesquisa ? de natureza bibliogr?fico-documental e traz como enfoque te?rico a Lingu?stica Textual (LT), a An?lise Textual dos Discursos (ATD), a Tradi??o Discursiva (TD) e os estudos sobre G?neros. A constru??o do modelo de avalia??o inicia-se pela discuss?o da origem, defini??o, elabora??o, fun??o, uso, estrutura, diretrizes normativas tipologia (forma) do tesauro mediante a realiza??o do seu estado da arte.

O modelo foi aplicado no Tesauro da Justi?a Eleitoral (TJE), corpus escolhido por melhor atender aos par?metros propostos: ?rea concentra??o, atualiza??o e padroniza??o normativa. Os resultados apontam que o TJE est? localizado no continnum da escrituralidade, com a predomin?ncia de aspectos descritivos e atos ilocucion?rios assertivos.

This thesis presents an interdisciplinary convergence between Linguistics and Information Science (IS) and its research object as the thesaurus. The problematic of the research is related to how the evaluation of thesauri is developed in IS, based on typological aspects such as: the theme/subject's thematic scope, its provision or organization, the level of specificity of the terms, and the language used. The study's main purpose is to build and apply a linguistic model assessment of thesauri, based on the articulation between the Textual Analysis of Discourses (TAD) and the Studies on Genres, considering its aspects: historical, textual, discursive and typological. The research is bibliographic, has a documentary nature and brings the theoretical approach of the Textual Linguistics (TL), Textual Analysis of Discourse (TAD), Discursive Tradition (DT) and Study of Genres. The construction of the model of evaluation begins by discussing the origin, definition, elaboration, function, use, structure, regulatory guidelines and typology (form) of the thesaurus, by the realization of their state of the art. A detailed account of the thesaurus's components was prepared through the articulation between the levels of analysis the plan of discourse and text, proposed by TAD (ADAM, 2011) and the Studies on Genres developed in Bakhtin (1997), Marcuschi (2008), Travaglia (2007), Adam (2011), Maingueneau (2008) and Koch and Oesterreicher (2007). The model was established in four steps: 1) analysis of the position of the thesaurus on continuum between orality and scripturality, 2) analysis of the textual dimension of the thesaurus, 3) analysis of the discursive dimension of the thesaurus, 4) analysis of the thesaurus typology. The model was applied in the Thesaurus of the Electoral Justice (TEJ), Corpus chosen by better serving the parameters proposed: area of concentration, updating and standardization norms. The results indicate that the TEJ belongs to the continuum of escriturality with the predominance of descriptive aspects and illocutionary assertive acts. Furthermore, it is the presence of a national and international toponymy that caters exclusively to the discursive community legal area, a procedure that is not covered in the regulatory guidelines. It is concluded that the thesis can contribute to expand studies focused on textual genres characterization that are underexplored by the TL, and promote advances on thesaurus's evaluation studies in the IS area as well.

Abstract:

O cultivo intensivo das áreas de baixa aptidão agrícola (solos pouco profundos em áreas declivosas) nas encostas basálticas do sul do Brasil tem contribuído para a degradação desse ambiente através do aumento das taxas de erosão e da produção de sedimentos. Programas de conservação do solo e da água têm sido implantados nessas áreas, ao mesmo tempo em que tem sido conduzidos estudos para verificar o impacto dessas práticas em relação à qualidade do solo e da água. Nesses estudos, estão sendo empregadas metodologias tradicionais de monitoramento combinadas com a utilização da modelagem matemática. Este trabalho teve como objetivo avaliar o modelo LImburg Soil Erosion Model (LISEM) na representação espacial dos processos hidrossedimentológicos de uma pequena bacia rural cultivada com tabaco, e também de verificar o efeito da combinação de práticas de controle da produção de sedimentos. Para isso, o modelo foi inicialmente calibrado a partir de dez diferentes eventos de precipitação. Os parâmetros de entrada utilizados para o modelo foram, na sua grande maioria, obtidos através de medições realizadas na bacia por vários autores. Para avaliar a habilidade do modelo em representar os processos hidrológicos e a distribuição espacial dos processos erosivos, foram utilizados hidrogramas e sedimentogramas medidos no exutório da bacia, e também um conjunto de informações referentes à localização de fontes de sedimentos (fingerprinting) e da distribuição espacial dos processos erosivos, através de um levantamento de campo. Para a avaliação das práticas de controle da produção de sedimentos, foram criados seis cenários onde combinou-se dois sistemas de preparo do solo (tradicional e mínimo) e manejo do ambiente ripário com uso de biofiltro e mata ciliar. Resultados mostraram que o modelo LISEM foi capaz de reproduzir adequadamente os hidrogramas para os dez eventos utilizados na calibração. Por outro lado, os valores de concentração de sedimentos em suspensão e da produção de sedimentos foram, na grande maioria das vezes, superestimados quando comparados com os valores observados. De uma maneira geral, para os eventos de maior intensidade, o modelo conseguiu reproduzir de forma razoável os padrões de erosão e deposição verificadas a campo. Quanto às simulações dos cenários, verificou-se a importância da presença do biofiltro e da mata ciliar para o controle da produção de sedimentos.
The intensive cultivation of the areas of southern Brazil that have poor agricultural potential (shallow soils on steep, basaltic hillsides) has contributed to the degradation of the environment by increasing rates of soil erosion and sediment yields. In this study, traditional monitoring methods have been combined with concurrent mathematical modeling to verify the effectiveness of the implementation of soil and water conservation practices on soil and water quality. This study seeks to evaluate the ability of LISEM (LImburg Soil Erosion Model) to spatially represent hydrosedimentological processes in a small rural catchment under tobacco cultivation. It also quantifies the effect of the combined practices in controlling sediment yield. The model was initially calibrated based on 10 rainfall events. The initial parameters used in the model were obtained, for the most part, from measurements reported in the literature. Observed hydrographs and sedigraphs for the outlet of the catchment were used to evaluate the model’s ability to simulate hydrosedimentologic processes. The spatial erosive processes simulated by LISEM were evaluated using both as sediment fingerprinting and a field survey. Six LISEM model scenarios were developed to evaluate the implemented sediment control practices. These included traditional versus minimum tillage, the implementation of buffer strips and riparian vegetation to protect the stream. The LISEM model was capable of adequately reproducing the hydrograph for the 10 calibration events. On the other hand, suspended sediment concentration and sediment yield were almost always overestimated by the model when compared to the measured values. In general, the model appropriately simulated observed patterns of erosion and deposition for the more intense rainfall events. The importance of buffer strips and riparian vegetation in controlling sediment yield was confirmed by the simulation modeling.

Estudos nacionais de evolu??o temporal constatam que a tend?ncia do consumo alimentar ? consistente com o incremento da preval?ncia de doen?as cr?nicas n?o transmiss?veis. Objetivou-se caracterizar padr?es alimentares de adolescentes de uma ?rea urbana do Nordeste do Brasil, relacionando-os aos marcadores diet?ticos saud?veis. Trata-se de um estudo transversal, com 430 adolescentes benefici?rios do Programa Nacional de Alimenta??o Escolar, em Natal, Brasil. Este estudo ? fruto de um planejamento realizado por equipe interdisciplinar e multiprofissional, constitu?da por profissionais de sa?de e estat?stica. O tamanho da popula??o de estudo foi definido por amostragem aleat?ria, em dois est?gios, e ponderada segundo n?mero de alunos de cada escola. O IMC foi utilizado para a avalia??o do estado nutricional (excesso de peso ≥ 25kg/m2). A avalia??o do consumo alimentar foi realizada a partir de entrevista semi-estruturada, sendo aplicados dois recordat?rios 24h, com intervalo de 30-45 dias, efetuados por equipe treinada com apoio de ?lbuns fotogr?ficos de medidas caseiras expressas em utens?lios e por??es. Os procedimentos e padroniza??es dos tipos de alimentos ou prepara??es relatados e respectivas convers?es em medidas caseiras foram feitos mediante adapta??es de per capitas e fichas t?cnicas de prepara??o. A estimativa do consumo de energia e fibras foi efetuada no ambiente do software Virtual Nutri Plus? (2007), modificado em rela??o ? lista de alimentos em mais de 90% dos itens. A informa??o nutricional dos alimentos foi obtida a partir da Tabela de Composi??o de Alimentos Brasileiros, National Nutrient Database for Standard Reference e r?tulos. A t?cnica de An?lise de Componentes Principais (ACP) foi utilizada para deriva??o de padr?es alimentares, conforme tr?s modelos anal?ticos de consumo: alimentos em gramas, energia em Kcal e fibras em gramas, resultando, respectivamente, em n? de componentes principais distintos, 7, 8 e 4, com vari?ncia acumulada superior a 70% e cargas fatoriais acima de 0,4. A associa??o entre vari?veis independentes e escores fatoriais de todos os componentes extra?dos foi aferida pela Raz?o de Preval?ncia (IC 95%). As caracter?sticas demogr?ficas e antropom?tricas dos adolescentes demonstram uma distribui??o proporcional em rela??o ao sexo e, em sua maioria, idade entre 10 e 13 anos, com estado nutricional x eutr?fico e filhos de mulheres com baixo n?vel de escolaridade. O Padr?o (1) Sistema Alimentar Tradicional puro (SATp) predomina no espectro do consumo alimentar dos jovens adolescentes, correspondendo ao primeiro componente de todos os modelos anal?ticos e representados pelo feij?o e os seus ingredientes de preparo. O Padr?o (2) Sistema Alimentar Combinado e de risco (SACr), coincidem nos componentes subseq?entes extra?dos a partir do consumo alimentar e de energia, com destaque para a ocorr?ncia de marcadores de alimenta??o n?o saud?vel, tais como a??cares refinados, gorduras saturadas e sal. O Padr?o (3) Sistema Alimentar Tradicional Modificado (SATm) e SATp s?o identificados nos demais componentes do modelo representado pelas fibras. As associa??es observadas, predominantemente do Padr?o SACr, distinguem-se por sexo, idade e estado nutricional. Os padr?es alimentares 1 e 3 caracterizam-se pela preserva??o do SAT e regional, bastante salutar, sob a perspectiva da preven??o de doen?as cr?nicas. O padr?o SACr representam alerta de risco ? sa?de, inclusive pela significante contribui??o energ?tica. Os achados podem subsidiar Pol?ticas de Aten??o ? Sa?de da Crian?a e Adolescente, em car?ter intersetorial

Changes are inevitable during the product lifecycle. These changes are due different needs, such as the knowledge evolution of business processes, environment or infrastructure changes, etc. Under these circumstances, it is crucial to have the control about the knowledge of what these changes mean to the system. Impact analysis represents the process that creates this knowledge. The impact analysis has a wide meaning for software development, such as the assessment of source code structures or the control of project management constraints. This thesis aims to present a model to analyze the impact in source code using ontologies in order to improve precision and recall of the identified source code structures compared to existing techniques. The use of ontologies integrates a semantic layer under the traditional techniques founded in syntactic analysis. To develop the impact analysis model, it was defined two different sub models: traceability and probability. The traceability model receives as input the source code and domain ontology and generates a traceability ontology populated with links between domain concepts (classes and properties) and source code units (classes, methods and attributes). These links are populated by a lexical and semantic analyzer that categorize, normalize (token generation, expansion and elimination) and compare (stemming) each token. With the traceability ontology and a change request, the probabilistic model classifies each traceability link using Bayesian Belief Networks. To the probability calculus, the node classification used the Google PageRank algorithm and the arrows used frequency analysis TFIDF and conceptual dependency, defined in this thesis. The impact analysis model was implemented as an Eclipse plugin and was empirically evaluated using three controlled experiments.
Mudan?as s?o inevit?veis durante o ciclo de vida do software. Estas mudan?as s?o resultado de diferentes necessidades, como a evolu??o do conhecimento sobre os processos de neg?cio, altera??es de ambiente, etc. Nestas circunst?ncias, ? crucial ter controle sobre o que essas mudan?as representam na aplica??o. A an?lise de impacto representa o processo que gera este conhecimento. Essa an?lise possui um significado abrangente dentro do desenvolvimento de software, incluindo desde a identifica??o de estruturas no c?digo fonte at? o controle das restri??es de gest?o de projeto. Esta tese apresenta um modelo para analisar o impacto no c?digo fonte de uma aplica??o utilizando ontologias, visando melhorar a precis?o e revoca??o de estruturas identificadas se comparadas a t?cnicas existentes. O uso de ontologias integra uma perspectiva sem?ntica nas t?cnicas tradicionalmente baseadas na an?lise sint?tica do c?digo fonte. Para o desenvolvimento do modelo de an?lise de impacto, foram definidos dois submodelos: o de rastreabilidade e o de probabilidade. O modelo de rastreabilidade recebe como entrada o c?digo fonte e uma ontologia de dom?nio e gera como resultado uma ontologia de rastreabilidade populada automaticamente com elos entre conceitos do dom?nio (classes e propriedades) e estruturas do c?digo (classes, m?todos e atributos). Estes elos s?o populados atrav?s de um analisador l?xico e sem?ntico que realiza a categoriza??o, normaliza??o (gera??o de tokens, expans?o e elimina??o) e compara??o (stemming). Com base na ontologia de rastreabilidade e em um requisito de mudan?a, o modelo probabil?stico classifica cada elo de rastreabilidade utilizando o modelo de Redes de Cren?as Bayesianas. Para o c?lculo de probabilidade, a classifica??o dos nodos utilizou o algoritmo PageRank do Google e das arestas, a an?lise de frequ?ncia TFIDF e a depend?ncia conceitual, definida nesta tese. Este modelo de an?lise de impacto foi implementado como um plugin do eclipse e foi avaliado empiricamente atrav?s de tr?s experimentos controlados.

O estudo dos antecedentes da qualidade em servi?os no setor hoteleiro ? uma recente oportunidade de pesquisa para o Marketing no contexto brasileiro, principalmente, devido ? import?ncia e crescimento desse segmento de servi?os de hospitalidade na economia do pa?s. O tema qualidade em servi?os ? muito debatido na academia no que se refere ? qualidade percebida pelo cliente. Por outro lado, h? car?ncia de estudos que pesquisam profundamente a gest?o em si, da qualidade em servi?os, ou seja, as vari?veis antecedentes da qualidade. Zeithaml, Berry e Parasuraman (1988) prop?em o Modelo Estendido da Qualidade em Servi?os. Esse modelo te?rico, tomado como base para esse estudo, apresenta trinta e sete (37) vari?veis antecedentes da qualidade agrupadas conforme o Modelo dos 5 Gaps (1985). Com base nos estudos de PZB, esse trabalho analisou os antecedentes da qualidade em servi?os hoteleiros de diferentes estruturas do Rio Grande do Sul junto a dez estabelecimentos hoteleiros. Para isso, identificou-se as a??es antecedentes de qualidade em servi?os em hot?is de diferentes estruturas, examinou-se a presen?a das vari?veis antecedentes de qualidade em servi?os e comparou-se as a??es de gest?o da qualidade em servi?os de hot?is de diferentes estruturas. A partir de um estudo qualitativo, preliminarmente foram entrevistados dez (10) profissionais expoentes da ?rea da qualidade a fim de validar o modelo te?rico de Zeithaml, Berry e Parasuraman (1988) para organiza??es de servi?os brasileiras. Posteriormente, com o modelo validado, foram entrevistadas mais dez pessoas que corresponderam a hoteleiros ou gerentes gerais de hot?is ou pousadas / estalagens. Os resultados apresentaram os antecedentes de qualidade em servi?os em hot?is de diferentes estruturas bem como apontaram semelhan?as e diferen?as dessas organiza??es em diferentes vari?veis como, por exemplo, recursos para qualidade e programas de qualidade.

The objective of this work is to verify if the credit rating model proposed by Brito and Assaf Neto (2008) designed for publicly held companies may also be applied to privately held companies in Brazil. In this work, 60 companies were used, being 30 of them in bankruptcy or insolvency processes in the period from 1994 to 2004, herein referred to as insolvent companies, and 30 of them with normal economic and financial situation referred here as solvent companies. In the present study, 60 companies were used; 30 of them presenting financial restrictions during the year of 2013 and 30 having a normal economic and financial situation. The model proposed by Brito and Assaf Neto (2008) used a logistic regression with 25 economic and financial indicators to see if they were able to separate solvent companies from non-solvent companies. Out of the 25 indicators used for this study, only 4 of them were statistically significant, namely: (I) retained profits on assets, (ii) financial debt, (III) net working capital and (IV) cash balance on sales. This four-variable model obtained a 90% accuracy in the correct classification of solvent and insolvent companies. However, the logistic regression model estimated based on the data from private companies showed different results from the one estimated by Brito and Assaf Neto (2008).In this case, only two variables showed to be statistically significant: (I) equity on assets and (II) cash balance on sales. This adjusted model reached a 57% accuracy in correctly classifying the companies. In short, the results presented here showed that it was not possible to estimate the adjusted credit-scoring model with a good accuracy for privately held companies in Brazil this based on extracted data from their financial statements.
O objetivo neste trabalho ?? verificar se o modelo de classifica????o de risco de cr??dito proposto por Brito e Assaf Neto (2008) desenvolvido para companhias de capital aberto tamb??m pode ser aplicado as companhias de capital fechado no Brasil. Nele foram utilizadas 60 companhias, sendo 30 com processos de concordata ou fal??ncia no per??odo de 1994 a 2004 denominadas insolventes e 30 com situa????o econ??mico-financeira normal denominadas solventes. No estudo aqui desenvolvido, tamb??m foram utilizadas 60 companhias; 30 apresentando restritivos financeiros durante o ano de 2013 e 30 com situa????o econ??mico-financeira normal. O modelo proposto por Brito e Assaf Neto (2008) utilizou uma regress??o log??stica com 25 indicadores econ??mico-financeiros para verificar se eles eram capazes de separar companhias solventes de companhias insolventes. Dos 25 indicadores utilizados, apenas 4 deles apresentaram signific??ncia estat??stica, sendo eles: (I) lucros retidos sobre ativo, (II) endividamento financeiro, (III) capital de giro l??quido e (IV) saldo de tesouraria sobre vendas. Esse modelo com quatro vari??veis obteve uma acur??cia de 90% nas classifica????es corretas das companhias abertas solventes e insolventes. No entanto, o modelo de regress??o log??stica estimado com base nos dados das companhias de capital fechado mostrou resultados distintos daquele estimado por Brito e Assaf Neto (2008). Nesse caso, apenas duas vari??veis se mostraram estatisticamente significantes: (I) patrim??nio l??quido sobre ativo e (II) saldo de tesouraria sobre vendas. Esse modelo ajustado obteve uma acur??cia de apenas 57% nas classifica????es corretas das companhias. Em suma os resultados aqui relatados mostraram que n??o foi poss??vel estimar um modelo ajustado de credit scoring com boa acur??cia para companhias de capital fechado no Brasil com base em dados extra??dos de suas demonstra????es financeiras.

The objective of this study was: to contextualize Ren? Ka?s theoretical model as a prospective method of depressive symptoms in the latency period (6 to 12 years). We set up a project with a group of five children, three boys and two girls, with score for depressive symptoms, whose group psychotherapy of the psychoanalytic approach was undertaken at a public school in S?o Paulo. The Ren? Ka?s method of "Analysis of the Group as a Dream", was the parameter to analyze the psychological associations occurred in the 17 sessions of the group, that interpreted from the drawings, body language and verbal children?s communication produced a corpus of knowledge concepts and models from Ren? Ka?s? theory, generating a methodological model for working with the specificities of this group of children. The analysis of the graphic material produced in the group, highlighted the role of drawings as the central process of free association and dissociation of their psychic material. Children, who came to the group, paralyzed by persecutory fantasies and defenses, might work their fears session to session, buoyed by the psychic space group through transference and regressive movements, captured in their drawings when analyzed by the parameter of the model of the dream reported to the group, allowing the groupanalyst locate the psychic development phases of the group, and their subjects. It was found that the children had some symptoms related to the family complex issues such as abandonment fantasy, fantasy image of the body, superego defenses and low self-esteem. The drawings proved to be: an interesting space as a transitional object to demobilize some children phantasmatic experiments related to space-body; possible to salvage some data about the more urgent conflict as: castration conflict, separation anxiety and individuation problematic. The inclusion of the other in the inter-play of the narrative-report in the group has become a way of testing analogical socialization for children who had emotional distress in a confrontation with the outside world, both spatial and human, then, it was from this relationship, established between group members and the group matrix, that children began to interact with the wider space of the setting, exploring other forms of expression. These unconscious formations occurring in the group could be accompanied by the concept of psychic organizers of Ka?s? theory, which allowed us to conduct a clinical strategy consonant with psychic development the group showed us. Finally, we concluded this work has expanded the scope of theoretical models and concepts of a theory which opens perspectives for other groupanalysts make possible a work with the criteria of group theory but, without moving away from the foundation of psychoanalysis, as it is necessary to support the specificities of age range from 6 to 12 years comprising the period of latency. Keywords: child, group psychotherapy, psychoanalysis, affective symptoms, depression.
O objetivo deste trabalho foi: contextualizar o modelo te?rico de Ren? Ka?s como m?todo prospectivo dos sintomas depressivos no per?odo da lat?ncia (6 a 12 anos). Para isto, foi montado um grupo de pesquisa com cinco crian?as, dois meninos e duas meninas, com score para sintomatologia depressiva, cuja psicoterapia de grupo de abordagem psicanal?tica foi empreendida em uma escola estadual em S?o Paulo. O m?todo "An?lise do Grupo como um Sonh" de Ren? Ka?s serviu como par?metro de an?lise das associa??es ps?quicas ocorridas no grupo durante 17 sess?es que, analisadas e interpretadas a partir dos desenhos, express?o corporal e verbal das crian?as, produziram um corpus de conhecimento dos conceitos e modelos da teoria de Ren? Ka?s, gerando um modelo metodol?gico de trabalho com as especificidades deste grupo de crian?as. A an?lise do material gr?fico, produzido no grupo, ressaltou a fun??o do desenho como centralizador do processo de livre associa??o e dissocia??o do seu material ps?quico. As crian?as, que chegaram ao grupo, paralisadas por fantasias e defesas persecut?rias, puderam trabalhar seus medos sess?o a sess?o, balizadas pelo espa?o ps?quico grupal atrav?s de movimentos transferenciais e regressivos que, transpareciam nos seus desenhos quando analisados pelo par?metro do modelo do sonho relatado no grupo, permitindo ao grupanalista localizar as fases de desenvolvimento ps?quico do grupo e, de seus sujeitos. Foi poss?vel constatar que as crian?as apresentavam alguns sintomas referentes ? problem?tica do complexo familiar, como a fantasia do abandono, fantasia da imagem do corpo, defesas superegoicas e baixa auto-estima. O desenho demonstrou ser: um espa?o interessante como objeto transicional para desmobilizar algumas experi?ncias fantas?sticas das crian?as relacionadas ao espa?o-corpo; possibilitou o resgate de alguns dados indiciais sobre os conflitos mais emergenciais das crian?as como o conflito da castra??o, fantasia da separa??o e a problem?tica da individua??o. A inclus?o do outro, no inter jogo da narrativa-relato do desenho no grupo, tornou-se um modo de experimenta??o anal?gica da socializa??o para as crian?as que apresentavam um sofrimento emocional no confronto com o mundo externo, tanto espacial quanto humano, pois, foi a partir desta rela??o estabelecida entre os membros do grupo e, no espa?o da matriz grupal, que as crian?as passaram a interagir com o espa?o mais amplo do setting, explorando outras formas de express?o. Essas forma??es inconscientes ocorridas no grupo puderam ser acompanhadas atrav?s do conceito dos organizadores ps?quicos da teoria de Ka?s, o que nos permitiu conduzir uma estrat?gia cl?nica consoante com o desenvolvimento ps?quico que o pr?prio grupo nos apontava. Conclu?mos, por fim, que este trabalho ampliou o campo de aplica??o te?rica de modelos e conceitos de uma teoria que abre perspectivas para que outros grupanalistas viabilizem trabalhos com os crit?rios da teoria de grupos sem, contudo, afastar-se da fundamenta??o psicanal?tica, t?o necess?ria para subsidiar as especificidades da faixa et?ria dos 6 aos 12 anos que compreende o per?odo da lat?ncia.

Abstract:

Studies of the relationship between market values and accounting numbers have long been a part of an established theme in capital markets research (CMR). These studies have taken various forms, most being conducted on a cross sectional basis, tied closely with the assumptions of equilibrium behaviour and efficient markets. Explanatory variables for market value have been dominated by firm-specific variables without incorporating macroeconomic variables. Recently, however, some studies have employed macroeconomic variables and dynamic specification in assessing the relationship between market values and accounting numbers (e.g. Bilson et al. 2001, Nissim and Penman, 2003, and Willett, 2003). The objective of this thesis is to investigate the nature of the relationship between share prices and accounting numbers on the Jakarta Stock Exchange for the period 1992-2002, using dynamic modelling principles in addition to the more usual cross sectional analysis. The approach to regression modelling (general-to-specific strategy)incorporated in this thesis relies less heavily than most CMR on prior economic theories of equilibrium behaviour. Apart from these novel aspects of approach and method, the study also provides valuable information about the emerging financial markets of Indonesia. The results of this thesis show that cointegration and the accompanying equilibrium correction relationship between market and book values for firms listed on the Jakarta Stock Exchange (JSX) can often be identified using accounting and macroeconomic regressors. The models are typically more informative, plausible and consistent than cross sectional models and are useful in interpreting the context in which the market to book relationship exists in Indonesia. A possibly surprising result is that in Indonesia, compared to similar models estimated using US data, the book value of net assets seems to have a stronger relationship with market value. This may be a function of the relative importance of financial statements as a source of information on the JSX.

O objetivo deste trabalho foi avaliar, atrav?s de an?lise por elementos finitos, o comportamento biomec?nico de uma t?cnica alternativa de distribui??o de implantes em overdentures e dois sistemas de attachments: Locator? (3i Implant Innovation) e Dal-Ro? (3i Implant Innovation). Foram estudadas as tens?es geradas em modelos tridimensionais variando-se a localiza??o ?nteroposterior dos implantes osseointegrados em uma mand?bula ed?ntula e o tipo de attachment. Foram gerados modelos tridimensionais de uma mand?bula ed?ntula a partir das imagens de tomografia computadorizada helicoidal, e dos attachments, da pr?tese total, da placa resiliente e dos implantes atrav?s de digitaliza??o a laser em tr?s planos. Foram constru?dos quatro modelos: modelo padr?o (MP) 1 - implantes inseridos na regi?o dos caninos (dentes 43 e 33) e sistema Locator; MP 2 implantes inseridos como no modelo 1 e sistema Dal-Ro, modelo alternativo (MA) 3 implantes inseridos na regi?o dos dentes 44 e 34 e sistema Locator, (MA) 4 implantes inseridos como no modelo 3 e sistema Dal- Ro. Os modelos geom?tricos foram importados para o programa ANSYS 10.0, no qual foi gerada a malha de elementos finitos. Uma carga vertical est?tica de 100 N foi aplicada sobre uma simula??o de bolo alimentar, na regi?o de primeiro molar inferior direito, sendo analisadas e comparadas as distribui??es de tens?o de Von Mises geradas. A maior ?rea de distribui??o de tens?o no rebordo alveolar ocorreu nos modelos padr?o com attachments Locator? e Dal Ro?, sendo o melhor desempenho conferido aos modelos alternativos em fun??o da menor ?rea de distribui??o das tens?es. Os modelos com attachments Dal Ro? mostraram-se mais favor?veis do ponto de vista biomec?nico em rela??o aos attachments Locator?, pois o padr?o de distribui??o de tens?es foi mais uniforme ao longo do seu eixo, apesar da magnitude dessas tens?es serem maiores nestes modelos. Pode-se concluir que a distribui??o ?ntero-posterior para os MAs com attachments Locator? e Dal Ro? apresentaram um comportamento biomec?nico vi?vel.

A artroplastia de coluna vertebral vem se consolidando a cada dia, como uma alternativa para os problemas de degenera??o de disco intervertebral de coluna. Por?m, a artrodese ainda ? a t?cnica mais utilizada como solu??o para problemas relacionados ? degenera??o de disco intervertebral de coluna, mesmo que pesquisas cl?nicas atuais demonstrem que os resultados obtidos com a aplica??o desta t?cnica n?o s?o satisfat?rios a m?dio e longo prazo [18]. No Brasil, a aplica??o de t?cnicas de artroplastia ainda ? muito restrita, principalmente quando se trata de cirurgias em pacientes que fazem parte da popula??o de classe baixa e m?dia, pois as pr?teses para artroplastia existentes no mercado s?o importadas e possuem altos pre?os. Por isso, realizou-se o desenvolvimento de uma pr?tese para substitui??o total de disco intervertebral, com objetivo de, utilizando tecnologia nacional, tornar a sua fabrica??o vi?vel, e, consequentemente, com custos reduzidos. A metodologia de desenvolvimento deste trabalho iniciou-se com o projeto assistido por computador, sendo fundamental a an?lise por elementos finitos do modelo computacional da pr?tese. Durante as simula??es virtuais, foram realizados ensaios est?ticos de compress?o axial e compress?o/cisalhamento, onde se observou que a pr?tese apresentou resultados de resist?ncia mec?nica acima do necess?rio para o uso pretendido. Estes ensaios demonstraram a viabilidade da fabrica??o de amostras para a realiza??o dos ensaios experimentais de compress?o axial est?tica. Por sua vez, os ensaios experimentais apresentaram um bom padr?o de repetibilidade entre as diferentes amostras, denotando a qualidade dos trabalhos realizados, bem como a uniformidade geom?trica e dimensional obtida na fabrica??o das amostras. Os ensaios experimentais apresentaram resultados muito pr?ximos aos encontrados nas simula??es computacionais, tornando-se poss?vel validar trabalhos realizados por elementos finitos, e confirmando que a pr?tese desenvolvida possui resist?ncia mec?nica acima do necess?rio.

The principal aim of this dissertation it's to verifying if the use of Information Technology (I.T.) in a Insurance Broker Company provides best information to this. The major emphasis in I.T. occurs in the implantation of a corporative data warehouse that lately should be used like a query source. In the proposed model, are use some others tools with specific application. First, it's proposed the Activity Based Costing (ABC) like a pattern for input data. It's be used in searching of the data quality. It's used too the Bayesian Theorem like a statistical tool in search of the best use for selected information during the decision-making process. Evaluating the use of data warehouse with this tools, it's make use of Quantified Exception Decision with the aim to compare the actual situation, the solution project and the future scenery. In the conclusion of this work, using DEQ tool, it was possible to prove the hypothesis of competitive improvement across the use of Information Technology (I.T.). It's proposed that I.T. can produce good effects to other kinds of companies and not only to Insurance Broker Companies.
O objetivo principal desta disserta????o ?? verificar se a utiliza????o da Tecnologia da Informa????o (T.I) em uma Corretora de Seguros faz com que a empresa obtenha melhores informa????es. A ??nfase maior em Tecnologia da Informa????o est?? a proposta de implanta????o de um data warehouse corporativo que posteriormente serviria de fonte de consultas. O modelo proposto, s??o utilizadas outras ferramentas com fins espec??ficos. Primeiramente, ?? colocado o custeio por Atividade (Activity Based Costing - ABC) como uma forma de padroniza????o na entrada de dados. Sua utiliza????o se d?? pela busca na qualidade dos dados. ?? utilizada tamb??m o Teorema de Bayes como ferramenta estat??stica na busca de melhor direcionamento das informa????es selecionadas durante o processo de tomada de decis??es. Avaliando a utiliza????o do data warehouse com estas duas ferramentas como acess??rios, faz-se uso da ferramenta de Decis??o por Exce????o Quantificada (DEQ) com o intuito de comparar a situa????o atual, do projeto da solu????o e do cen??rio futuro. Na conclus??o deste trabalho, por meio da ferramenta DEQ, foi poss??vel a comprova????o da hip??tese de gera????o de melhores informa????es atrav??s da utiliza????o da Tecnologia da Informa????o (T.I.). Tamb??m sugere-se que a T.I. pode produzir efeitos ben??ficos em outras empresas e ao somente a Corretoras de Seguros.
