Nascimento, Rui Fonseca. "Which factors determine firm survival?" Master's thesis, Instituto Superior de Economia e Gestão, 2015. http://hdl.handle.net/10400.5/13084.
Texto completoEste estudo tem como finalidade analisar quais as variáveis que afectam a sobrevivência das empresas que atuam na indústria transformadora portuguesa. A análise de sobrevivência será efetuada através de 1130 empresas, correspondendo estas as empresas nascidas no período de 2005 a 2009. A base de dados utilizada no estudo SCIE tem como base a publicação reportada pelo Instituto Nacional de Estatística (INE). A nossa análise de sobrevivência é centralizada em cinco variáveis de uma empresa: Crescimento, Dimensão, Tecnologia, Indicadores financeiros e o Sector. De forma a determinar o impacto destas variáveis na sobrevivência utilizamos o modelo de regressão de Cox. Antes de efetuarmos uma análise pelo modelo de regressão de Cox o comportamento das variáveis independentes foi analisado através do modelo de Kaplan-Meier onde podemos concluir que o segundo e terceiro ano de operação apresentam-se como os anos em que as empresas verificam maiores taxas de mortalidade (estas foram de cerca de 10% em cada ano). Analisando o modelo de Cox fomos incapazes de rejeitar todas as hipóteses efetuadas.
The main aim of this empirical study is to determine which factors influence the survival of new Portuguese companies. We will do so through survival analysis of 1130 companies born in the Portuguese manufacturing sector between 2005 and 2009. The database used SCIE, based on the report published by the INE. Our survival analysis is centered on five company variables: Growth, Size, Technological, Dimension, and Sector. To determine the impact of these variables on survival we used the Cox regression model. Before we ran an analysis through the Cox model we also studied the behavior of the variables through a Kaplan-Meier survival estimate, where we concluded that the second and the third year are those in which firms present the highest mortality rates (about 10% in each year). Moving into the Cox regression analysis, we were unable to reject any of our original hypotheses.

Texto completoO actual foco no envelhecimento activo torna o empreendedorismo sénior um fenómeno de crescente relevância. Pouco se conhece sobre as motivações do empreendedorismo sénior e ainda menos sobre os seus efeitos. Esta tese produz conhecimento sobre os empreendedores seniores e analisa o seu desempenho empresarial do ponto de vista objectivo e subjectivo. Assenta em teorias de diferentes disciplinas, como a gerontologia, psicologia e economia. Adicionalmente, analisa dados primários (um questionário) e secundários (“Quadros de Pessoal”). A investigação contempla quatro contributos principais. Primeiro, é desenvolvido e aplicado na revisão da literatura um esquema conceptual de análise do empreendedorismo sénior. Verifica-se uma carência de investigação sobre o desempenho organizacional das empresas. O segundo contributo reflete a realidade Portuguesa do empreendedorismo sénior, verificando-se que os seniores mostram uma reduzida vontade de enveredar pelo empreendedorismo, admitindo-se que as causas estejam relacionadas com os níveis de burocracia, a reduzida dinâmica dos mercados e uma cultura pouco orientada para o desempenho. Em terceiro lugar foi analisado o impacto do capital humano na criação de empresas, e da idade no desempenho organizacional. Concluiu-se que possuir experiência empreendedora e profissional está positivamente relacionada com a criação de empresas por seniores. Adicionalmente, os resultados confirmam o efeito negativo da idade no desempenho organizacional. O último contributo analisa o nível de satisfação do empreendedor para com a empresa. Verifica-se que aspetos monetários e não-monetários são, ambos, relevantes; assim como ter experiência na indústria afeta positivamente a satisfação, ao passo que um período de desemprego superior a 12 meses, prévio à criação da empresa, afeta negativamente a satisfação. Esta tese tem implicações no desenho de políticas públicas relacionadas com empreendedorismo e em futura investigação. Aqui, admite-se que a utilização do conceito de idade percebida pelo próprio (em lugar da idade cronológica) possa ser um indicador útil na adesão e desempenho do empreendedor. O efeito negativo do desemprego anterior à criação da empresa deve ser reconhecido e abordado pelos decisores políticos.
Senior entrepreneurship is a phenomenon of growing interest due to the current focus on active ageing. Little is still known about the determinants of senior entrepreneurship and less regarding its outcomes. This thesis provides insights about senior entrepreneurs and examines firm performance from subjective and objective levels. It is based on a multi-theory approach, from gerontology, psychology, to economic theories. Moreover, primary and secondary data was adopted: a questionnaire and a national database “Quadros de Pessoal”. The research has four main contributions. First, a framework of analysis is developed and applied to review senior entrepreneurship literature. A lack of evidence related to firm performance was found and more theory-based articles should be developed. Second, the Portuguese reality of senior entrepreneurship is examined and we find that Portugal faces an older population who exhibits a low willingness to engage in entrepreneurship, probably due to the levels of bureaucracy, low market dynamics, and a culture not oriented to performance. Third, we explore the impact of human capital traits on firm creation and of age on firm performance. Having entrepreneurial and paid employee experience is positively related to firm creation for older individuals. Furthermore, our results confirm the negative effect of being older on firm performance. Fourth, we examine business satisfaction among senior entrepreneurs –monetary and non-monetary are both important to explain business satisfaction and having industry experience positively affects business satisfaction, whereas having spent more than 12 months unemployed immediately before founding affects it negatively. The thesis leads to implications for policy makers and future research, namely on the appropriateness of considering self-perceived age (instead of chronological age) as an indicator influencing entrepreneurship. The negative effect of unemployment status before startup should be acknowledged and tackled by policy makers.

Trata-se de uma abordagem teórica sobre Propriedade Intelectual com ênfase em Trade Secrets como barreira à entrada. Os avanços em criptologia no campo da matemática podem vir a se somar aos esforços teóricos desenvolvidos em Microeconomia em Organização Industrial. Neste contexto, a criptologia é resgatada historicamente e são apresentadas suas principais funções na Propriedade Intelectual, em especial no Trade Secrets. Questiona-se aqui: Por que as empresas criptografam seus processos produtivos? A propriedade intelectual em especial os Trade Secrets tem desempenhado importante papel, enquanto barreira à entrada na economia contemporânea? Como a criptologia e seus respectivos desenvolvimentos na matemática podem contribuir para o fortalecimento do segredo industrial? Percebe-se que apesar da presença marcante da criptografia e dos bens incorpóreos na Economia Contemporânea, ainda são escassas as análises teóricas, os estudos de caso e os bancos de dados sobre Propriedade Intelectual e principalmente, sobre Trade Secrets. Contribui ao explicitar seus conceitos e alertar para a importância de intensificação de pesquisa científica sobre o tema possibilitando, dessa forma, uma melhor compreensão da dinâmica econômica empresarial na atualidade.
This work presents a theoretical approach on intellectual property with emphasis in trade secrets as entry barriers. Progress in cryptology in the field of the mathematics can be added to the theoretical efforts developed in microeconomics in industrial organization. In this context, cryptology is rescued historically and its main functions are presented in the intellectual property, especially in trade secrets. This research questions: Why do the firms cryptograph their productive processes? Has intellectual property, especially trade secrets, been playing an important role as a barrier to entry in the contemporary economy? How can cryptology and its respective developments in mathematics contribute to the strengthening of the industrial secret? It is noticed that in spite of the outstanding presence of cryptography and of the incorporeal goods in the contemporary economy, the theoretical analyses are still scarce, as are case studies and databases on intellectual property and mainly, on trade secrets. This research contributes to explication of its concepts and warns about the importance of intensification of scientific research on this topic, in order to reach a better understanding of managerial economical dynamics at the present time.

Texto completoThis work analyzes the role of relational contracts in the decision between subcontracting or vertical integration and the conditions that make these contracts feasible. The propositions of Baker, Gibbons and Murphy (2002 since now, just BGM) and Dixit (2004) are tested and the results are supportive to the main propositions. Firms can conduct their operations through the market or can operate in a high degree of vertical integration. In the second case firms avoid what we call holdup problems - that is, when it comes time to work out the terms of the deal left open at the outset, the other side might demand terms of trade that are onerous but not so onerous that the first part would willingly forfeit the value of those transaction-specific assets by taking its business elsewhere. If all this assets belongs to one firm, there is no problem at all, and that explain this second choice, the vertical integration (Williamson, 1985). This rationale, however, dont explain why some companies operate through networks, arrangements where the parties stay economically separate entities but having long-term relationship. Toyota and others Japanese Automobile Companies are the typical example (Holmström, Roberts, 1998). Relational contracts help circumvent difficulties in formal contracting no matter if these difficulties come from holdup problems or from another source. A relational contract allows the parties to utilize their detailed knowledge of their specific situation and to adapt to new information as it becomes available (MacNeil, 1978). There is a caveat, however: they cannot be enforced by a third party and must be self-enforcing, that means, the value of the future relationship must be sufficiently large that neither party wishes to renege (BGM, 2002, Dixit, 2004). But what makes some contracts to breakdown until others goes well? BGM examine the problem in the light of relational contracts and property rights theory. According to them, integration affects the parties temptation to renege a given relational contract. Thus, in a given environment, a desirable relational contract might be feasible under integration but not under nonintegration and this will be particularly true when we face a wide varying alternative prices of an asset. These assets are not restricted to physical ones, and can be even a legal title to a good or the discretion that a outsourced worker have about how to allocate his time doing the job (Hart, 1992). Dixit (2004) discuss the role of signalization and formal contracts in the maintenance of these relational contracts. Departing from these hypotheses and with ground on the incentive literature, the BGMs and Dixits propositions were tested. The companies decision between to contract law services in the market or to employ an internal legal department can be explained mainly by the variation on assets value (in the case, the value of legal services, expressed by a greater competition degree Bertrand, 2004), but also by the institutional environment, particularly the time to reach a decision and the variability of the expected result. The results of the empirical research confirm the main assumption and point some lines of research in the relational contracts field.

O crescimento do uso de documentos eletrônicos nas mais diversas atividades da sociedade vem atrelado à necessidade de garantias de autenticidade e integridade desses documentos, entre outras. Para esse fim, tem-se empregado normalmente assinaturas digitais em conjunto à Infraestruturas de Chaves Públicas (ICPs), principalmente do modelo X509. Contudo, observa-se que os modelos de assinatura digital proeminentes na atualidade são complexos e inconvenientes para os usuários finais. Neste trabalho são agrupados os principais problemas relacionados a esses modelos de assinatura e é proposta uma nova abordagem, centrada nas necessidades do usuário final. O foco está na melhoria de três aspectos: a) a complexidade do processo de assinatura sob a perspectiva do usuário final; b) o custo da manutenção da assinatura a longo prazo; c) o modelo de confiança exigido no processo de assinatura. O novo modelo proposto é uma revisão do modelo de assinatura como um todo, descartando certificados e a ICP X509 em favor de estruturas simples e relacionamentos de confiança naturais, modelados nas assinaturas manuscritas convencionais.
Abstract : The growth in the use of electronic documents in various activities within society comes coupled with the necessity for, among others, authenticity and integrity guarantees upon these documents. Digital signatures in conjunction with Public Key Infrastructures (PKIs), mainly the X509 model, have commonly been employed to that end. However, we observe that current mainstream digital signature schemes are complex and inconvenient for end users. We group the main problems related to these schemes and propose a new approach, centered on the needs of the end user. Therefore, we focus on the improvement of three aspects: a) the complexity of the signature process from the end user perspective; b) the cost of long-term signature maintenance; c) the trust model required by the signature process. The new proposed scheme is a redesign of the overall signature process, discarding certificates and the X509 PKI in favor of simple structures and natural trust relationships modeled on conventional handwritten signatures.

Texto completoIn recent years, internationalization has been the subject of several studies and many companies have seen it as an increasingly feasible goal thanks to globalization and this phenomenon has allowed that Born Global Firms (BGF) to achieve this goal in a short time and go abroad since its inception. At the same time, the market has originated groups of entrepreneurs who have developed fast-growing and scalable businesses known as startups. Recently, in Peru, startups are beginning to take greater strength thanks to the participation of public and private entities of the ecosystem. In this context, the research aims to identify the main factors that help to develop a Peruvian startup like a BGF. For this purpose, the study applied qualitative techniques based on interviews to experts and representatives of some born global startups of the ecosystem. In addition, as part of the quantitative study, surveys were conducted to eighty startups that allowed develop statistical analysis of the relationship between the proposed factors and the possibility of getting international startups. In this way, with the qualitative and quantitative results, it was concluded that the global vision of business model is the main factor to develop a born global startup in the Peruvian ecosystem. Furthermore, it was determined that the previous experience of the founders and networking are critical factors to provide a better global vision. In contrast, financing was identified as a factor of value added to the model but not determinant for the internationalization of a startup.

Texto completoRoutine measurements of soil water content (neutron probe) and matric potentials (tensiometers), were made in a soil with a rubber tree plantation and a "Terra Firme" forest, during 1985 and 1986, in Manaus. The soil moisture content in the rubber tree plantation was greater than 70% of the storage capacity, and during 10 months (November to August), the drainage process was detected. The largest water storage variation, associated with the dry season of 1985, was (-27.4 ± 6.6) mm, over the (0-170) cm layer, showing the main radicular activity in the depths ranging from 50 to 120 cm, as a consequence of surface compaction. In the forest, even during the wet season (January to April), significant amounts of water were absorbed by the vegetation at the surface layer, related with short dry spells, which stop temporarly the drainage process. The highest quantity of water extracted by the root system was (-57.0 ± 7.0) mm, down to 170cm depth, and the soil moisture was maintained above 60% of the soil storage capacity. The average daily evapotranspiration in the forest, estimated in 1985 was (3.4 ± 0.4) mm/day; in the rubber tree plantation, the estimative was (2.5 ± 0.6) mm/day, or a difference of 27% in relation to the Terra Firme forest.

Texto completoA comunicação no contexto da intervenção em enfermagem é uma pedra basilar e, especificamente, a comunicação com a pessoa em fim de vida é uma área particular pela distinta competência profissional que exige. Esta foi a temática selecionada para desenvolver, durante um percurso de estágio em três contextos diferentes, competências de enfermeiro especialista na área de Enfermagem Médico-Cirúrgica. A temática intitulada “Comunicação com a Pessoa em Fim de Vida: Intervenção de Enfermagem” deve-se a uma necessidade pessoal de desenvolver competências nesta área mas, também para responder a uma necessidade da equipa de enfermagem. O presente relatório evidencia o percurso efetuado, através de uma análise crítica e reflexiva do mesmo, com base na evidência científica e ancorada na Teoria de Enfermagem Centrada na Pessoa apresentando os resultados obtidos. Nos dois primeiros momentos de estágio desenvolvi competências técnicas, científicas e relacionais na área tendo, para tal, utilizado a pesquisa bibliográfica, a observação da prática, a discussão com peritos da área, a colaboração na prestação de cuidados e a reflexão baseada na metodologia reflexiva do Ciclo de Gibbs na qual foram mobilizados os conhecimentos teóricos atuais e as recomendações para as boas práticas. No terceiro momento, que corresponde ao meu contexto de trabalho, apliquei as competências desenvolvidas nos locais anteriores e intervi junto da equipa de enfermagem. Inicialmente foi realizado um questionário para a identificação das principais áreas de interesse da equipa de enfermagem, no âmbito da comunicação com a pessoa em fim de vida, e posteriormente foram planeadas sessões de formação para dar resposta aos temas identificados. No serviço ficou disponível um poster sobre a transmissão de más notícias, um folheto informativo sobre a gestão do impacto da má notícia e uma pasta partilhada nos computadores com documentos sobre as temáticas, sendo acessível a toda a equipa. Pretendo, num futuro próximo, continuar a aprofundar este tema e realizar formações de cariz prático para a equipa de enfermagem no âmbito do treino de estratégias comunicacionais.

These municipalities have very different characteristics, such as buildings, natural and semi-natural vegetation as well as agriculture, thus making it interesting to see how the elements fire and wind influence in landscape balance of this territory. The fires were studied in detail, with the main aims of understanding the affected areas, but also to identify the starting points associated to each fire and finally understand the dynamic transitions in land use. The study allowed a better understanding of the association of the direction(s) of dominant wind with the area burnt, and also allowed to question the accuracy and precision of the indicated location of the starting points in relation with the likely development of fire under the influence of the dominant winds

Texto completoThe use of polymers in soybean seeds has been accomplished with the purpose of incorporating products like insecticides, fungicides, growing substances, minor fertilizers and so on, in order to improve the visual aspect of the seed, to promote smaller operator's intoxication risk and to provide a better seeds' acting and seedlings after sowing. The main objective of this work was to evaluate the recovered seeds' effects in soybeans seed quality lots of high and low germination of the cv. AG 7000. The seed's film coating was accomplished with two commercial marks of polymers, LABORSAN ® , and LANXESS ® , in doses of 2 and 3,5 ml for each kg with and without mixture of the fungicide Carbendazim + Thiram (firewalk ® ). The seeds' quality evalutions, were measured by the germination test, germination in sand and accelerated aging. The use of polymers in soybean seeds provides seeds with good appearance and coloration and can be applied to differentiate the seed from the commercial grain. The fungicide and the polymers do not affect the physiological quality of soybean seed. The results of the polymers and fungicide were superior in the test of accelerated aging, showing higher germination in relation to the check treatment.
O uso de polímeros em sementes de soja vem sendo realizado com a finalidade de incorporar produtos fitossanitários, melhorar o aspecto visual da semente, promover menor risco de intoxicação do operador e proporcionar um melhor desempenho de sementes e plântulas após a sua semeadura. O objetivo principal deste trabalho foi avaliar o efeito do recobrimento na qualidade de semente de soja de alta e baixa germinação da cv. AG 7000. O revestimento foi realizado com duas marcas comerciais de polímeros, LABORSAN ® , e LANXESS ® , nas doses de 2 e 3,5 mL para cada kg de semente com e sem mistura do fungicida Carbendazim + Thiram (firewalk ® ). As avaliações da qualidade das sementes foram realizadas por meio do teste de germinação, germinação em substrato de areia e envelhecimento acelerado. O uso de polímeros na semente de soja proporciona sementes com boa aparência e coloração, podendo ser aplicado para diferenciar a semente do grão comercial. O fungicida e o polímero não prejudicam a qualidade fisiológica da semente de soja. Os resultados do polímero e fungicida foram superiores no teste de envelhecimento acelerado, apresentando maior percentual de germinação em relação à testemunha.

Texto completoNew multimedia applications that use the Internet as a communication media are pressing for the development of new technologies, such as: MPLS (Multiprotocol Label Switching) and DiffServ. These technologies introduce new and powerful features to the Internet backbone, as the provision of QoS (Quality of Service) capabilities. However, to obtain a true end-to-end QoS, it is not enough to implement such technologies in the network core, it becomes indispensable to extend such improvements to the access networks, what is the aim of the several works presently under development. To contribute to this process, this Thesis presents the RSVP-SVC (Resource Reservation Protocol Switched Virtual Connection) that consists in an extension of RSVP-TE. The RSVP-SVC is presented herein as a mean to support a true end-to-end QoS, through the extension of MPLS scope. Thus, it is specified a Switched Virtual Connection (SVC) service to be used in the context of a MPLS User-to-Network Interface (MPLS UNI), that is able to efficiently establish and activate Label Switched Paths (LSP), starting from the access routers that satisfy the QoS requirements demanded by the applications. The RSVP-SVC was specified in Estelle, a Formal Description Technique (FDT) standardized by ISO. The edition, compilation, verification and simulation of RSVP-SVC were made by the EDT (Estelle Development Toolset) software. The benefits and most important issues to be considered when using the proposed protocol are also included
O protocolo proposto nesta Tese, denominado Resource Reservation Protocol Switched Virtual Connection (RSVP-SVC), que consiste numa extens?o do RSVP-TE, vai de encontro ao surgimento de novas aplica??es multim?dia, que usam a Internet como meio de interconex?o. Tais aplica??es pressionam pelo desenvolvimento de novas tecnologias, tais como: MPLS, DiffServ e RSVP-TE, que introduzem novas e eficientes caracter?sticas ao backbone Internet, proporcionando uma significativa diferen?a no que tange ? provis?o de QoS (Quality of Service). O presente trabalho leva em conta o fato de que para se conseguir uma QoS fim-a-fim verdadeira, n?o basta implementar tais tecnologias no n?cleo da rede, ? imprescind?vel, estender tais melhorias ?s redes de acesso e qui?? ?s redes locais. Nesse sentido, muitos trabalhos est?o atualmente em desenvolvimento. ? no intuito de contribuir com este processo que este trabalho apresenta a defini??o de uma UNI MPLS SVC atrav?s do RSVP-SVC. Essa extens?o d? ao RSVP-TE a capacidade de estabelecer t?neis LSP (Label Switched Path) a partir de conex?es discadas, ampliando portanto o escopo de utiliza??o do MPLS, levando-o at? ?s redes locais atrav?s das redes de acesso, e provendo tamb?m suporte a uma QoS fim-a-fim verdadeira. O RSVP-SVC foi especificado em Estelle, que ? uma linguagem de especifica??o formal padronizada pela ISO. A edi??o, compila??o, verifica??o e simula??o do RSVP-SVC foi feita atrav?s do programa EDT (Estelle Development Toolset). Ademais, tanto os benef?cios quanto ?s quest?es mais importantes a serem consideradas quando do uso deste protocolo s?o apresentados

Texto completoProton exchange membrane fuel cells (PEMFCs) are attractive for applications in transportation, stationary and portable devices owing to their high-power density, high efficiency, ease of operation and low/zero emissions. Despite their salient features, PEMFCs large commercialization is impeded due to the utilization of expensive and scarce platinum-based electrocatalysts. Many non-noble materials have been explored so far to replace Pt and obtain similar or better catalytic activity. Among them, cerium oxide (CeO2), has been considered as the promising candidate as electrode material for PEMFCs because of its redox properties and the ability to dissociate H2 molecules in the absence of noble metals. In addition, modification of CeO2 with aliovalent cationic species, has been identified as a promising method to reduce the activation barrier for H2 dissociative adsorption on the surface of CeO2. Herein, we investigate the modifications induced in Cu-modified CeO2 epitaxial ultrathin films, used as well-controlled model systems, during the interaction with H2. CeO2 ultrathin films, doped with different concentrations of Cu, were grown by reactive molecular beam epitaxy and their chemical and morphological properties during thermal reduction cycles in UHV and H2 were studied, using in-situ X-ray photoelectron spectroscopy (XPS) and scanning tunneling microscopy (STM). XPS spectra provided quantitative information on the concentration of Ce3+ ions, O-vacancies and OH-groups on the surface during the interaction with H2. The results are interpreted also with the help of density functional theory calculations performed by a group of collaborators. Also, Cu nanoparticles (NPs) supported on CeO2 ultrathin films were studied under the same conditions. Along with the reducibility of ceria, the stability of Cu NPs on these surfaces has been investigated using STM. The experimental results indicate that the Cu atoms as dopant and NPs supported on the surface of CeO2 tend to increase the reducibility of Ce atoms as the electrons released during the O-vacancy formation and H2 dissociation are acquired mostly by Ce ions. The increase in the concentration of OH groups during thermal treatments in H2 can be ascribed to the lower H2 dissociation barrier on the Cu-modified surfaces than on pure ceria. However, also Cu atoms are reduced from +2 to +1 along with the Ce atoms during dissociative adsorption of H2 on the surface. The formation of Cu1+ significantly decreases the H2 dissociation barrier. The surface morphology of the films is not altered significantly after the H2 thermal reduction cycles. In-operando NEXAFS studies on the Cu doped films at APE-HE beamline at the ELETTRA synchrotron allowed to study the evolution of the oxidation state of Ce and Cu during thermal treatments in H2 at near ambient pressure. The results confirmed a partial reduction of Cu atoms to the +1 state and its influence on the reduction of Ce as well as on H2 dissociation.

Texto completoA fase de fim de vida corresponde a uma situação de saúde particular, de grande vulnerabilidade, por analogia com outras fases de transição do ciclo vital, mas com a peculiaridade de se reportar ao seu fim. Nesta fase, a doença oncológica assume características que se traduzem na indispensabilidade de cuidados paliativos ao doente, assim como aos cuidadores familiares, cujo apoio constitui um dos pilares que sustenta a filosofia dos cuidados paliativos. Este relatório descreve as aprendizagens do 3º Semestre do Curso de Mestrado e Pós de Licenciatura de Especialização em Enfermagem Médico-Cirúrgica, na área de Opção em Enfermagem Oncológica. O percurso de desenvolvimento de competências fundamentou-se nas filosofias de Cuidados Paliativos, de Collière e de aquisição de competências de Benner. O objetivo geral foi: desenvolver competências técnicas, científicas e relacionais no âmbito da prestação de cuidados de enfermagem aos cuidadores familiares da pessoa com doença oncológica em fim de vida. Como metodologia saliento a revisão atualizada da literatura recorrendo ao motor de busca da Google, EBSCOhost e a bases de dados (CINAHL e MEDLINE), repositórios universitários e pesquisa bibliográfica. Acrescem as atividades realizadas nos ensinos clínicos, pautadas pela prática reflexiva segundo o Ciclo de Gibbs. Como resultados, desenvolvi e adquiri competências pessoais e profissionais que permitiram otimizar o meu desempenho e dinamizar a equipa do serviço de medicina interna onde exerço funções, para a implementação de ações paliativas visando a excelência dos cuidados de enfermagem. Elaborei um panfleto com informações úteis, destinado aos cuidadores familiares, um dossier com artigos científicos para consulta pela equipa e, em co-autoria com duas enfermeiras, iniciei a elaboração de um manual de boas práticas intitulado: “Comunicação com o doente em fim de vida e seus cuidadores familiares: orientações práticas”.

Texto completoThe study deals with the relationship between related party transactions (RPT\'s) and firm performance in the Brazilian \"Novo Mercado\", and its goal is to identify whether this relationship can be affected by mechanisms of corporate governance. Audit committee was used to measure corporate governance mechanisms. The two assumptions made by Gordon, Henry and Palia (2004), called \"conflicts of interest\" and \"efficient transactions\" were considered in this study. In an attempt to measure these relationships, it was adopted the model of panel data analysis to reduce the problem of omitted variable bias. The empirical results provide evidence that there is a relationship between related party transactions and firm performance. However, the results regarding the moderating effect of the mechanisms of supervision and use of such contracts have been inconclusive.

Texto completoEste trabalho visou realizar um estudo sobre a relação entre literatura e cinema, na educação. Tratou especificamente da produção de textos audiovisuais adaptados de textos literários, com alunos da terceira série do Ensino Médio do Instituto Federal de Educação, Ciência e Tecnologia Campus Araguatins. O objetivo principal desta investigação foi analisar as relações entre literatura e cinema no que concerne ao ensino de Literatura no Ensino Médio, propondo uma forma diferenciada de articular Literatura e Cinema, Educação e Cinema na escola. A dissertação também pretendeu apresentar o cinema como dispositivo produtor de conhecimento e não meramente como recurso didático em sala de aula, para desvelar as possibilidades educativas produzidas a partir do cinema; buscou apontar, assim, o cinema não como arte secundária à literatura, mas como arte independente da mesma, apesar de alimentar-se dela. A abordagem da pesquisa foi qualitativa. A coleta de dados foi executada por meio da pesquisa-ação e diálogo organizado com os alunos, que pretendeu discutir a percepção do aluno litecineasta, em relação ao cinema e seus limites e potencialidades para o ensino da Literatura. Para o embasamento teórico utilizou-se autores como Walter Benjamin, Robert Stam e Adriana Fresquet. Esse trabalho buscou contribuir tanto para estudos de adaptação cinematográfica quanto agregar valor à discussão sobre sua presença no ensino de Literatura.

Texto completoThis work aims to investigate the existence of heterogeneity in the quality of accouting information after the adoption of IFRS. The adoption of IFRS is generally associated with an increased quality of the financial statements. However, companies within the same country probably have different economic incentives regarding the disclosure of information. Accordingly, treat companies evenly, without considering the linked economic incentives, could contaminate the identification of information quality after the adoption of IFRS. It examined the case of Brazil, a country classified as code-law, whose tax laws induced the accounting practice and whose adoption of IFRS is mandatory. First, Brazilian companies listed on the BOVESPA were separated into two groups, namely: companies issuing ADRs to the adoption of IFRS and the companies that have not issued ADR to the adoption of IFRS. Then, this second group of companies were grouped by means of a cluster analysis in two different subgroups based on economic incentives in common. Then, based on the identified groups, the accounting quality information is tested for each group before and after the adoption of IFRS. This work uses the timely recognition of economic events, value relevance of net income and earnings management as proxies for the quality of accounting information. The results suggest that a particular group of companies obtained, in fact, an increase of accounting information quality after adoption of the IFRS in Brazil. This group of companies would have sufficient incentives to leave behind the accounting and tax compliance and provide superior quality to your set of accounting information disclosed. In addition, a second group of companies with quality of accounting information was checked before and after 2008. In contrast, a third group of companies has been identified that did not show quality of accounting information either before or after 2008. These results support the assumption that incentives at the level of companies have an important role in the quality of financial statements. This does not imply stating that accounting standards do not matter, but that there are other drivers that shape the quality of financial statements and accounting standards should be seen as one of those drivers.

Texto completoThe economic history of the last two decades has seen the exponential growth of the goods and services flows with a pace never seen before. Next to the commercial trade of finished goods it has taken place the trade of components and semi-finished goods. Consequently, this is contributing to the growth of Global Value Chains (GVC), that become the heart of the new organization of international labour. Given the magnitude of this phenomenon, the more and more open and global production chains are nowadays a real paradigm of the industrial organization. For this reason the structural change must be taken into consideration in both the economic analysis and the policies of economic planning, especially at regional level, given that nowadays the national level has lost much of its sovereign power. After having analysed these changes, the research focuses on the productive system of the Emilia-Romagna region, which has one of the strongest manufacturing sector among European regions. The Emilia-Romagna region is historically hosting a remarkable number of productive agglomerations and, as such, since decades, it is a model largely studied among the local production systems which are based on territorial proximity. Nowadays, the economic growth is prone to award always longer production chain and for this reason we are witnessing the serious issue of disintegration between, the medium and large enterprises situated at the top of the global value chains on one side, and the small firms focusing on subcontracting activity on the other side. This polarization involves a high risk of mortality for a large part of the regional productive system with all the problems that this entails. The analysis will initially focus on the dynamic of the international trade to move on the foreign direct investments in both inward and outward directions. Then the focus moves on firms having their headquarters placed in Emilia-Romagna. We classify each company in relation to its proprietary status, in order to identify if internationalized companies (in – out – in&out), present a structural profile and economic results differentiated from those not internationalized. A (micro)econometrics analysis then follows. Both empirical and theoretical literature show that multinational firms exhibit a competitive advantage before investing abroad. However, there are no clear empirical results regarding the ex-post effects of foreign direct investment (FDI) on firm performance, partially due to the lack of available firm-level data. We build a new firm-level dataset able to provide reliable measures of key performance indicators, especially Total Factor Productivity (TFP). We then use a Propensity Score Matching together with a Difference-In-Differences approach, to analyze the causal relationship between FDI and firm performance. The results confirm the existence of an “ex-post premia” for internationalized companies, relative to all the four performance variables considered (Revenues, Value added, TFP, Total salary and wages). Empirical evidence on Emilia-Romagna case is lacking, despite the subject is relevant to its policy implications.

Texto completoThis project focuses on the development of an industrial process, in which a coupled absorption/distillation unit is developed to treat gaseous effluents contaminated by a Volatile Organic Compound (VOC). Absorption is performed in a falling film microabsorber. The first stage of this work consists in characterizing the mass transfer in this device. The gas/liquid absorption of Perchloroethylene (PCE) by Di (2-EthylHexyl) Adipate (DEHA) is used as test case. Experiments showed the feasibility and the benefit of this separation process operated in a micro-contactor. Indeed, the purification efficiencies obtained are comparable to those of conventional processes (97%). Moreover, the required absorption solvent quantities are very low. A parametric study revealed significant mass transfer intensification on gas side and a gain in compactness due to the minimization of gas cavity thickness (2mm) and gas flowrate. This study also showed the limits of microabsorbers to handle large gas flowrates with good efficiencies, due to a low influence of gas velocity on the mass transfer coefficient. This behaviour was explained, thanks to 2D simulations, by a significant dispersion of concentration profiles, which indicates a diffusion limitation. The latter comes mainly from smooth laminar flow and the small size, a typical characteristic of micro-processes. To overcome this limitation, turbulence should be promoted in the gas. The second stage of this work concerns the microabsorber extrapolation from laboratory scale to industrial SMEs, based on the numbering-up concept. Calculations predict high throughputs with a microstructured absorber of competitive efficiency (95%) and high compactness (area occupied ˜ 0.5 m2). For profitable operation, solvent absorption recycling by a flash distillation is studied. The results lead to a promising treatment technique, which still requires a theoretical and experimental validation of the coupled absorber-distiller unit

Texto completoThe study of color in the cinema has reached relevant research dimensions throughout the first decade of the 00\'s. Several publications have mapped the broadest theme in which color is put in film analysis. Therefore, it is possible to revisit some past works and move on to new looks and interpretations. Under the domain of the color, I propose the film analysis of Pierrot le fou (Jean-Luc Godard) and Le bonheur (Agnès Varda). In the investigation of the chromatic system of these moviemakers, it is possible to evaluate interdisciplinary questions like the representation of France in the 60\'s and gender relations.
