By focusing on character, humor, and loose narrative, I create a world full of quirky, pitiful creatures that blur the lines between illustration and "Fine Art". Inspired by golden age cartoons, Pop-Surrealism, and late 50's commercial art, I make work that speaks of the awkwardness of human emotion while keeping a "tongue in cheek" attitude about everyday life. This work is expressed through illustration, animation, sculpture, and a lot of sarcasm.M.F.A.

People are not always rational, rely on heuristics and are influenced by situational factors being conducive to biased decisions. Hence, the decision outcome cannot be explained by consumers’ preferences exclusively. This offers opportunities to service managers to steer the decision outcome into a desirable direction by a beneficial design of situational factors. In contrast to the discussed opportunities, situational factors can also become a pitfall for researchers and managers. I show that situational factors may compromise the validity of research results based on self reports in a service context, because the reported scores of research participants may be biased. Three perspectives related to service management are distinguished in this thesis: First, the customer independently of the service provider; second, the interaction of customer and service provider; third, the service provider independently of the customer. From the perspective of the customer, I investigate the impact of different defaults in a customization process on the decision outcome of different types of customers. From the perspective of the customer and service provider interaction, I point out a new solution to overcome a dilemma related to service productivity. Finally, from the perspective of the service provider, the possible contamination of service related constructs by socially desirable responding is examined.

The distribution of beetles in the Family Silphidae has not been well studied in Virginia. The primary purpose of this study was to survey silphid beetles in a more systematic manner across different geographic regions of the state, with a special consideration for Nicrophorus species. The seasonal abundance and diversity of silphid beetles in Montgomery County, Virginia, was also examined. Baited pitfall traps were used to sample beetle distribution and abundance, and were placed in each of the five geographical regions of Virginia in the summers of 2007 and 2008. Traps were placed approximately one kilometer apart and were checked daily over a five day period for each of three sampling periods. A total of 4375 silphid beetles, consisting of 11 species in four genera, were collected in ten counties with beetles in the subfamily Silphinae being predominant. Within the Nicrophorinae, Nicrophorus tomentosus and N. orbicollis were dominant in 2007; whereas in the summer of 2008, N. tomentosus and N. pustulatus were the most commonly collected. Contingency analyses indicated that species abundance was associated with sampling period and geographic region. Nicrophorus americanus was not collected during either summer of surveying and only three N. carolinus were trapped in Suffolk County in the summer of 2008. For the Montgomery County survey, a total of 3276 beetles were found between the middle of April and the middle of October. The prevalent species within Nicrophorinae was Nicrophorus tomentosus and within the Silphinae it was Necrophila americana. Species abundance was associated with sampling period.Master of Science in Life Sciences

Insects are one of the important elements for the Agroforestry action and handling, once they can act as material decomposers, cultivations powerful pollinator and herbivorous. This work aimed to evaluate the Entomological Fauna which is
associated to implementation period of Agroforestry Systems, using Nelder s pattern. The research was realized on Experimental Fields of Agroecological Studies belonging to Instituto Federal de Educação, Ciência e Tecnologia de Sergipe, at Tabuleiros Costeiros region, in São Cristóvão SE city. The insects related to eight Agroforestry Systems: eucalyptus + corn (SEM), eucalyptus + beans (SEF), teak + beans (STF), teak + corn (STM), gliricidia + beans (SGF), gliricidia + corn (SGM), leucaena + corn (SLM ) and leucaena + beans (SLF). The monthly collects of insects were realized from February to September/2012, with pitfalls traps aids. In all evaluated systems, the insects that are from Hymenoptera line contrasted in the previous period to the implementation of Agroforestry Systems, while the partners of Diptera line were more expressive in the post period. Coleoptera was the order of the richest families in both periods. The family Formicidae was the most representative, independently of the collect period. The biggest number of insects was noted after
the implementation of Agroforestry Systems. The SLF presented the hugest number of individuals, the SLM and SLF the hugest wealthy of families and the SEF, the hugest variety of insect families. The composition of insect families was highly similar among the evaluated Agroforestry Systems. The obtained results indicate that the rainy period, the available food offer, the variety of vegetal species, the distance among the systems and the collect method which were used, influenced in the Entomofauna levy associated to Agroforestry Systems.Os insetos são um dos componentes importantes para o funcionamento e manejo dos Sistemas Agroflorestais, uma vez que podem atuar como decompositores de materiais, polinizadores e herbívoros potenciais das culturas. O presente trabalho teve como objetivo avaliar a fauna entomológica associada à fase de implantação de Sistemas Agroflorestais utilizando modelo Nelder. A pesquisa foi realizada no Campo Experimental de Estudos Agroecológicos, pertencente ao Instituto Federal de Educação, Ciência e Tecnologia de Sergipe, na região dos Tabuleiros Costeiros, no município de São Cristóvão-SE. Foram analisados os insetos associados a oito Sistemas Agroflorestais: eucalipto + milho (SEM), eucalipto + feijão (SEF), teca + feijão (STF), teca + milho (STM), glirícidia + feijão (SGF), gliricídia + milho (SGM), leucena + milho (SLM) e leucena + feijão (SLF). As coletas mensais de insetos foram realizadas de fevereiro a setembro/2012, com auxílio de armadilhas pitfalls. Em todos os sistemas avaliados, os insetos da ordem Hymenoptera destacaram-se no período anterior à implantação dos Sistemas Agroflorestais, enquanto que os representantes da ordem Diptera foram mais expressivos no período posterior. Coleoptera foi a ordem com maior riqueza de famílias em ambos os períodos. A família Formicidae foi a mais representativa independentemente do período de coleta. Maior abundância de insetos foi observada após implantação dos Sistemas Agroflorestais. O SLF apresentou maior abundância de indivíduos, o SLM e SLF maior riqueza de famílias e o SEF maior diversidade de famílias de insetos. A composição de famílias de insetos foi altamente similar entre os Sistemas Agroflorestais avaliados. Os resultados obtidos indicam que o período chuvoso, a oferta de alimento disponível, a diversidade de espécies vegetais, a distância entre os sistemas e o método de coleta utilizado, influenciaram no levantamento da entomofauna associada à fase de implantação dos Sistemas Agroflorestais.

Melo, Aranha Ana Luiza. „Corruption at the local level in Brazil: decentralization as a pitfall?“ Politai, 2015. http://repositorio.pucp.edu.pe/index/handle/123456789/91849.
Der volle Inhalt der QuelleAnnotation:
Recently, Brazil has undergone decentralization processes that could have strengthened the local level in democratic terms. Notwithstanding, the results of these processes were not con-sensual, and corruption persisted as a feature of the Brazilian local level.This paper focuses on the corrupt conduct of municipal public officials who deal with fe- deral funds transferred by the central government. The information collected is part of a profile of corruption in the cities monitored by the federal Executive, revealing both how this phenomenon is distributed in terms of areas and which possible factors can explain the occurrence of corrup- tion in the Brazilian local governments. This paper deals with corruption in the municipalities of Minas Gerais - one of the 26 Brazilian states - from a conception of corruption as the misuse offunds by the political system.The argument focuses on the conduct of municipal public officials who deal with federalfunds transferred to Minas Gerais´ municipalities. In order to conduct this study, we used the reports from the Program of Inspections from Public Lotteries produced by the Office of the Comp- troller General (CGU). First, we built a general profile of the situation in those cities surveyed by the CGU regarding the incidence of irregularities. By doing so, we highlighted which gover- nmental areas would be in a more critical situation. These irregularities, in turn, were taken as proxies for the occurrence of corruption in two different ways. In the first place, according to the amount of irregularities found – which included all kind of irregularities, from formal mistakes to overbilling –, statistical tests were performed in order to establish which factors could be taken as constraints of corruption at the local level. We identified political, social, economic and demo- graphic characteristics that were associated with corruption, in its petty form. On the other hand, we also categorized corruption in a more strict way, considering only the cases in which larger amounts of resources were involved and leaving out the formal irregularities.We demonstrated that not all factors related with corruption in its broader sense (population size, the characteristic of the transfers, municipal characteristics related to income, education and control) kept significantly associated with the incidence of more severe irregularities. We seek to contribute to the debate about whether or not the local level is more susceptible to corruption, which means discussing if decentralization can be understood as a pitfall.Recientemente, Brasil ha experimentado procesos de descentralización que podrían haber fortalecido el nivel local en términos democráticos. No obstante, los resultados de estos procesos no han sido consensuados y la corrupción ha persistido como una característica del nivel local en este país.El presente artículo se centra en la conducta corrupta de autoridades municipales que se ocupan de los fondos federales transferidos por el gobierno central. La información obtenida forma parte del perfil de corrupción en ciudades supervisadas por el Poder Ejecutivo federal. Asi- mismo, revela cómo este fenómeno se distribuye en función de las áreas gubernamentales y qué posibles factores pueden explicar la presencia de corrupción en los gobiernos locales brasileños.Este artículo se ocupa de la corrupción, entendida como el mal uso de fondos por parte del sistema político, en las municipalidades de Minas Gerais, uno de los 26 estados de Brasil. El argumento se centra en la conducta de las autoridades municipales que se encargan de los fondos federales. Para llevar a cabo este estudio, se utilizaron los informes del Programa de Inspecciones por Sorteos Públicos elaborados por la Oficina de Contraloría General (CGU). En primer lugar, se construyó un perfil general de la situación de las ciudades encuestadas por la CGU en relación a la incidencia de irregularidades. Al hacerlo, se destacaron las áreas gubernamentales que estarían en una situación más crítica. Estas irregularidades, a su vez, fueron tomadas como indicadores indirectos de incidencia de la corrupción de dos maneras diferentes. Por un lado, de acuerdo a la cantidad de irregularidades encontradas –que incluían todo tipo de irregularidades, desde errores formales hasta sobrefacturación– se aplicaron pruebas estadísticas con el fin de establecer qué factores podían ser tomados como limitaciones de la corrupción a nivel local. Se identificaron características políticas, sociales, económicas y demográficas, asociadas con la corrupción. Por otro lado, se definió la corrupción de una manera más estricta, tomando en cuenta solo los casos que involucraban grandes cantidades de recursos y se dejó de lado las irregularidades formales. Se demostró que no todos los factores relacionados con la corrupción en su sentido más amplio (tamaño de la población, características de las transferencias, características municipales relacionadas con los ingresos, educación y control) se mantienen significativamente asociados a la incidencia de irregularidades más graves. Se busca así contribuir al debate sobre si el nivel local es más susceptible o no a la corrupción, lo cual significa discutir también si la descentralización puede ser entendida como un obstáculo.

Der volle Inhalt der QuelleAnnotation:
In Lebanon, there is a common understanding and belief among many politicians and citizens, in equal measure, that Lebanon is a democratic country. This belief is not only restricted to those inside Lebanon, but also to be found in neighbouring Arab countries and among their people. In other words, Lebanon is believed to be a country that enjoys a relatively democratic political system, rule of law, and a vibrant civil society, compared to the rest of the region. However, this is for the most part a misunderstanding, and originates from most Lebanese people’s view that a modest level of freedom should be considered democracy, and that a relatively unconstrained civil society means an effective civil society. The main purpose of this thesis is to analyse Lebanon’s political system and establish a clearer picture about whether the democratic claim is real or just an illusion. In order to build this picture, I have concentrated on the internal and external obstacles that have impeded the evolution of the Lebanese political system. The first part of the thesis discusses whether or not the Lebanese political system shares any of the features of functioning democratic political systems and whether or not it is running in a modus which reflects democratic values. In later chapters, the thesis moves on to examine the internal and external factors that have hindered the state from becoming a sovereign, authoritative state and thus without the necessary foundations for becoming a democratic state. The study will demonstrate that Lebanon suffers from the domination of a militant organisation within its borders which violates the country’s sovereignty and disrupts the government and its institutions from functioning properly and being authoritative. Moreover, it will reveal that most citizens - a key element in any democracy - continue to feel subjugated, unable to make their voices heard, and without a say in the decision making process. Moreover, it will be demonstrated that Lebanon suffers from several problems. Firstly and most importantly, it suffers from the lack of an effective state that imposes the rule of law on all of Lebanon’s territory. Secondly and equally important, Lebanon suffers from missing a major component that constitutes an essential pillar for the state, and that is sovereignty. Thirdly, election results are not taken into consideration as the public’s electoral choices are not respected, while instead powerful elite continues to rule the country illegally. These impediments and many others lead the study to conclude that the Lebanese political system currently remains far from being considered a democracy.

Inter-firm collaborations have become an indispensable part of business strategy to deal with faster competitive dynamics and higher market and environmental uncertainties. Interestingly, research has found that around half of all cooperative relationships take place between competitors. Termed as coopetition , it refers to the simultaneous cooperation and competition between at least two actors. Over the past two decades, coopetition has become an important domain for industrial practice which has led to increasing research interest by scholars worldwide with a wide range of subjects studied within the extant body of literature. Despite the growing interest, coopetition research is still fragmented and is dominated by conceptual research. This entails limitations to knowledge and understanding reflected by heterogeneous uses of the coopetition concept (mixed definitions and a lack of clarity in how to apply coopetition successfully), a lack of generalisability, and a limited number of quantitative studies. Coopetition scholars commonly argue that competitors rarely cooperate in activities that are close to customers, known as output activities (e.g., sales and marketing), but instead argue that they mostly cooperate in activities far from the customer, referred to as input activities (e.g., R&D, logistics, and NPD). However, it has been found in real world business examples that competitors also cooperate in output activities. In this study these two distinct types of coopetition are termed as internally focused coopetition (cooperating with competitors in input activities) and externally focused coopetition (cooperating with competitors in output activities). This is the first study synthesising these two types of coopetition in one conceptual model, and examining their individual paybacks and pitfalls. After the development of the conceptual model based on the relevant literature, a cross-sectional research design is adopted and an online survey is implemented among Chief Operating Officers and Managing Directors in UK high-tech companies. A total of 148 completed questionnaires are collected. Data analysis employs a two-stage approach, which includes a measurement model assessment and a structural model assessment. The results indicate that both internally and externally focused coopetition can help firms to develop new knowledge-based resources and capabilities. However, these two types of coopetition also have different paybacks and pitfalls. Even though the new innovation knowledge-based resources and capabilities gained from internally focused coopetition can lead to better business efficiency and effectiveness, firms also lose uniqueness in their existing knowledge-based resources and capabilities (a key tenet of competitive advantage in resource- and knowledge-based theories). In contrast, externally focused coopetition has no significant impact on uniqueness, but the new marketing knowledge-based resources and capabilities negatively influence business efficiency and effectiveness. It has also been found that when firms perceive that their competitors are behaving opportunistically, they tend to do the same and appropriate more knowledge-based resources and capabilities from the collective value created. Competitors opportunism also renders more loss of uniqueness, which in turn worsens business performance. This research provides greater clarity and understanding to scholars of the workings of coopetition for deriving new knowledge-based resources and capabilities and extrapolating performance benefits from this. This work also illuminates situations where coopetition does not result in the perceived win-win-win situations indicated in literature. Based on these results, a number of theoretical and managerial contributions are developed. Principally, (1) this is the first study that conceptualises and operationalises internally and externally focused coopetition, and their individual knowledge-based outcomes are analysed from a knowledge-based view; (2) how competitors opportunism affects the dynamics of coopetition is better understood from a game theoretical perspective; (3) this study extends the understanding of business performance outcomes of coopetition.

A redução da biodiversidade nos agroecossistemas afeta populações de insetos predadores devido à limitação de recursos para o seu desenvolvimento. O controle biológico conservativo diversifica o agroecossistema e aumenta à presença de inimigos naturais, incrementando o controle de pragas. As plantas herbáceas além de aumentar a biodiversidade do hábitat, exercem influência na composição das comunidades de insetos no campo incrementando o controle biológico conservativo. O objetivo deste estudo foi avaliar a diversidade, distribuição e sazonalidade de besouros associados ao solo em plantio de soja (Glycine max (L.) Merrill) com faixas de plantas herbáceas nas bordas. O estudo ocorreu entre novembro de 2014 e setembro de 2016 em Jaboticabal-SP. As amostragens foram realizadas com armadilhas tipo alçapão, em dois hectares de área cultivada. Foram analisados os índices de diversidade, abundância, distribuição espacial e sazonalidade de besouros associados ao solo. Resultados evidenciaram maior ocorrência de besouros carabídeos nas faixas de plantas herbáceas. Scarabaeidae e Staphylinidae, por sua vez, não obtiveram crescimento populacional nas áreas de maior diversidade vegetal. A distribuição de espécies de Carabidae e Scarabaeidae foi apresentada de forma agregada sendo que a ocorrência dos insetos dessa família foi influenciada principalmente pela temperatura e umidade relativa.
The reduction of plant diversity in agroecosystems can affect predator insect populations due to the restriction of shelter and food resources. Studies about the role of herbaceous plants have shown the increase of biodiversity and the influence of composition and distribution on predator insects communities in the field. These dates may assist in the elaboration of the conservative biological control management programs. The aim of this study was to evaluate the diversity and abundance of ground beetles in the agroecosystem with soybean crop (Glycine max (L.) Merrill) and evaluate the dispersion of these insects in the habitat. The study was performed between 2014 November and 2016 September in Jaboticabal- SP. The essay was made in the field with 2 ha of soybean crop and herbaceous plant in two edges and the sample was performed with pitfall traps. The dates were analyzed and the diversity, abundance, seasonality indexes and spatial distribution of insects were calculated. The results pointed out that herbaceous plants affect positively the carabid beetle occurrence, but not affect Scarabaeidae and Staphylinidae. The distribution of insects was aggregate in the agroecosystem and the meteorological factors affect the occurrence of Carabidae and Staphylinidae beetles.

Previous issue date: 2008O objetivo deste trabalho foi estudar a estrutura de comunidade de escarabeíneos em dois ambientes do Refúgio Ecológico Charles Darwin. Foram realizadas 15 coletas em ambiente aberto e de mata no R E C D, Igarassu PE. Para realização destas coletas foram utilizadas 24 armadilhas de solo (pitfall) e seis armadilhas de interceptação de vôo. As coletas com pitfall foram realizadas entre janeiro e dezembro de 2006 e abril e julho de 2007. Essas coletas foram mensais e tiveram duração de 48 horas, sendo utilizadas iscas de carne apodrecida e fezes humanas. Já as interceptações de vôo permaneceram no campo entre abril e julho de 2007, sendo revisadas a cada 15 dias. Foram coletados 2560 escarabeíneos, pertencentes a 40 espécies e 16 gêneros nas armadilhas pitfall, enquanto na interceptação de vôo foram capturados 5169 indivíduos, pertencentes a 17 gêneros e 40 espécies. Os resultados das coletas com pitfall mostraram que os dois ambientes apresentam diferenças em aspectos da estrutura de comunidade de escarabeíneos, como composição de espécies, abundância, riqueza e diversidade. Os escarabeíneos foram mais atraídos pelas iscas de fezes humanas quando comparado à carne bovina apodrecida. Os dados obtidos pelo uso dos estimadores de riqueza indicaram uma estimativa máxima de 44,18 espécies para o ambiente aberto e 23 para mata. Foi verificada uma correlação positiva entre os dados de precipitação com a abundância, a riqueza e a diversidade de espécies no ambiente aberto. Entre as espécies exclusivas desse ambiente foi registrado o mesmo número de generalistas (5) e coprófagas (5), enquanto para as espécies exclusivas da mata foi verificado um maior número de generalistas (6), seguido pelas coprófagas (2). A comparação entre os métodos de coleta indicou que a abundância de um determinado grupo pode ser subestimada com a utilização de apenas um ou poucos métodos de captura uma vez que esses métodos são mais eficientes para capturada de algumas espécies em detrimento de outras

This report highlights the complexity of engaging in a post-acquisition integration process of a relatively large knowledge-intensive firm. Findings from a case study is analyzed in relation to previous theory, resulting in four propositions aiming at creating a foundation for further theory development, as well as increased understanding among practitioners in relation to the emphasized problem. It is argued by the authors that increased relative acquisition size of knowledge-intensive firms will: 1) increase demand for a centralized organizational structure, 2) decrease benefits of introducing a new top management, 3) decrease communicative attention towards lower levels, and 4) decrease attention towards subcultures. These factors will ultimately increase the risk for integration failure.

In Paper [I], we theoretically assess green public procurement (GPP) as an environmental policy instrument and its ability to lead to the achievement of environmental objectives. Central to our analysis is the extent to which polluting firms choose to adapt to the public sector's environmental requirements and to invest in greener technologies. Our main finding is that the potential of GPP to function as an objective-effective instrument of environmental policy is limited and can actually be counterproductive. From an environmental policy point of view, it is crucial that GPP aims for environmental standards beyond just the technology of the polluting firms and that it is designed with reference to defined environmental objectives. In Paper [II], we use data on Swedish public procurement auctions for internal regular cleaning service contracts to provide novel empirical evidence regarding GPP and its effect on the potential suppliers' decision to submit a bid and their probability of being qualified for supplier selection. We find only a weak effect on supplier behavior, and this suggests that GPP, as used in practice, does not live up to its political expectations. However, several environmental criteria appear to be associated with increased complexity, as indicated by the reduced probability of a bid being qualified in the post-qualification process. As such, GPP appears to have limited or no potential to function as an environmental policy instrument. In Paper [III], I examine how GPP is organized in Sweden and how the potential suppliers respond to varying buyer market shares using data on Swedish public procurement auctions for internal regular cleaning service contracts. The level of GPP stringency is found to vary systematically across authority types, buyer market share, and political coalition in the relevant council or in Parliament. The results also indicate quite a substantial dispersion in GPP stringency, suggesting a low degree of coordination among contracting authorities when implementing the policy. After controlling for GPP stringency and other covariates, increased buyer market share is associated with a significant increase in the probability of potential suppliers submitting a bid. The European Commission encourages public authorities to split procurement contracts into multiple contracts in order to increase the competiveness of small and medium sized enterprises (SMEs). In Paper [IV], I use data from Swedish public procurement auctions for internal regular cleaning service contracts to study the effect of contract size and number of contracts on SME participation and probability of winning. The results indicate that SME participation is negatively related to both contract size and the number of contracts in the procurement. A possible interpretation is that reduced contract size in order to stimulate SME participation is counteracted by reduced incentives for them to enter into procurements with multiple contracts. Medium-sized firms are also more successful when bidding for smaller contracts relative to large firms. Nevertheless, the results indicate that the award rate for SMEs is positively correlated with the number of contracts in the procurement.Green Public Procurement: An Efficient Environmental Policy Tool?

Thesis (PhD (Chemistry and Polymer Science))--University of Stellenbosch, 2007.In this thesis the main capillary electrodriven chromatographic techniques (i.e. Capillary Electrochromatography CEC, Micellar Electrokinetic Chromatography MEKC and Microemulsion Electrokinetic Chromatography MEEKC) were compared in terms of column manufacturing, fundamental chromatographic performance, and some applications were developed. The first stage of this thesis aimed at developing improved packed and open tubular CEC columns. For the manufacturing of packed CEC columns, the frit-burning step proved of critical importance, together with the slow build-up of the packed bed. The making of open tubular columns is a relatively simple, "one pot" sol-gel reaction taking place in mild conditions. The nature of the gel and the resulting selectivity of the column could easily be changed by changing the precursors. In a second stage of this thesis the packed and open tubular CEC columns were evaluated chromatographically and compared with the results obtained by MEKC and MEEKC. All electrodriven separation techniques showed high efficiencies. The selectivity proved easier to tune with sol-gel chemistry for the making of open tubular columns. Resolution is acceptable for packed CEC, MEKC and MEEKC. For peak capacity, CEC has the advantage of a practically non-limited elution time, while MEKC and MEEKC suffer of the drawback of the existence of an elution window which is limited in time by the elution of the micelles. Some applications were developed in this study on open tubular CEC columns and for the packed CEC columns. Various sugars derivatized with 9- aminopyrene-1,4,6-trisulfonic acid (APTS) could be separated with open tubular CEC, using an octyl, amino or cyano stationary phase. Open tubular columns containing α, β and γ cyclodextrins attached to the stationary phase were developed. This approach proved promising for the separation of positional isomers. A method was developed for the analyses of a mixture of carbamates and for several steroids with packed column CEC directly coupled with MS.

Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorA savana (Lavrado) de Roraima ocupa 17% de seu território. Estas áreas apresentam um mosaico de vegetações e uma diversidade pedológica devido aos fatores de formação do solo. As formigas estão presentes praticamente em todos os ambientes terrestres e desempenham inúmeros papéis no ecossistema. O objetivo desta pesquisa foi avaliar as relações entre as características físicas e químicas do solo com as assembleias de formigas em uma área de savana próxima de Boa Vista, RR, situadas no Campus do Cauamé/UFRR. O trabalho foi desenvolvido nas 12 parcelas permanentes do Programa de Pesquisa em Biodiversidade (PPBio). Foram utilizadas duas técnicas de coleta (iscas e pitfalls), sendo instaladas10 subamostras em cada parcela, separadas 25 m uma da outra, totalizando 120 sub-amostras por método de coleta. Os pitfalls permaneceram em operação por 48 horas e as iscas ficaram expostas por 40 minutos. O material foi coletado e levado ao laboratório para identificação. Os dados químicos e físicos do solo foram obtidos através dos metadados disponíveis no site do PPBio. Adicionalmente foram coletadas as variáveis umidade e resistência a penetração (RP). Os dados das classes de solo foram obtidos de estudos detalhados do campus Cauamé. As assembleias de formigas foram ordenadas com base na presença/ausência dos indivíduos utilizando o escalonamento multidimensional não-métrico (NMDS). Para verificar a influencia das variáveis ambientais sobre a distribuição das formigas, foi realizada uma Analise Multivariada da Variância (MANOVA). A similaridade entre as técnicas de coleta foram analisadas com o teste de Mantel. Na área de estudo identificou-se cinco classes de solos, e nestas foram coletadas 8936 formigas distribuídas em 7 subfamílias, 22 gêneros e 49 espécies onde 39 são morfotipos. A espécie Kalathomyrmex emery foi registrada pela primeira vez para o estado de Roraima. Os gêneros mais abundantes ncontrados nas iscas foram Crematogaster (46,3%) e Camponotus (25,5%). A similaridade entre as técnicas pitfall e isca foi baixa (35%), porém o pitfall foi 92% similar as duas técnicas em conjunto. Dentre as variáveis ambientais testadas, verificamos que não houve diferença significativa em relação às classes de solo, umidade e pH com a distribuição das formigas, sendo que a argila foi à única variável que influenciou em sua distribuição. Os pitfalls podem ser o único método de coleta de formigas em áreas de savanas. A maior riqueza de espécies de formigas foi verificada no Latossolo Amarelo. O solo com menor riqueza foi o Gleissolo, porém, foi o que apresentou maior número de espécies exclusivas.
Savanna (Lavrado) of Roraima occupy 17% of its territory. These areas have a mosaic of vegetation and pedological diversity due to factors of soil formation. The ants are present in virtually all terrestrial environments, and playing numerous roles in the ecosystem. The objective of this research was to evaluate the relationships between the physical and chemical characteristics of soil with ant assemblages in a savanna area near Boa Vista, Roraima (Campus Cauamé/UFRR). The study was conducted in 12 permanent plots of the Biodiversity Research Program (PPBio). We used two techniques (baits and pitfalls), and 10 sub-samples from each plot, 25 m apart from each other, a total of 120 sub-samples using the method of collection. The pitfalls remained in operation for 48 hours and the baits were exposed for 40 minutes. The material was collected and taken to the laboratory for identification. The chemical and physical soils were obtained from the metadata available from the PPBio. Additionally we collected moisture content and resistance to penetration (RP). Data from the soil classes were obtained from detailed studies of Cauamé campus. Ant assemblages were sorted based on the presence / absence of individuals using non-metric multidimensional scaling (NMDS). To check the influence of environmental variables on the distribution of ants, we performed a Multivariate Analysis of Variance (MANOVA). The similarity between the techniques was analyzed with the Mantel test. In the study area were identified five classes of soil, and these were collected 8,936 ants distributed in 7 subfamilies, 22 genera and 49 species which are 39 morphotypes. The species Kalathomyrmex emery was first recorded for the state of Roraima. The most abundant genera were found in the bait Crematogaster (46.3%) and Camponotus (25.5%). The similarity between the techniques and bait pitfall was low (35%), but the pitfall was 92% similar the two techniques together. Among the environmental variables tested, we found that there was no significant difference in the classes of soil, moisture and pH with the distribution of ants, and the clay was the only variable that influenced the distribution of ants. The pitfalls may be the only method of collecting ants in savanna areas. The highest species richness of ants was found in the Yellow Latosol. And the soil with less wealth was the Gleysol, however, was the soil with the highest number of exclusive species.

Pests and natural enemies populations on the soil surface in different soybean no tillage cultivation systems were evaluating during the growing season of 2006/2007, in Dourados town, Mato Grosso do Sul state, Brazil, at 22o 11’ of latitude South and 54o 56’ of longitude West. The experimental area was constituted by three cover conditions of the soil surface: sorghum, pearl millet, spontaneous vegetation, with posterior soybean direct seeding. Four and two evaluations, using pifall traps, were made, respectively, at the pre-sowing and at the early season periods of soybean seeding. Data were analyzed as measures repeated in time, with posterior comparison between means. The abundance and relative frequency were calculated for the two evaluation periods. Gryllus assimilis (Orthoptera: Gryllidae) and Lagria villosa (Coleoptera: Lagriidae) were, respectively, the most abundant pest species, before and after soybean seeding. Solenopsis sp. (Hymenoptera: Formicidae) was the most abundant natural enemy before and after soybean seeding. The sorghum/soybean and pearl millet/soybean systems significantly modified the population density of these species and of the predators Galerita collaris (Coleoptera: Carabidae) and Calosoma granulatum (Coleoptera: Carabidae). G. collaris accompanied the population dynamic of G. assimilis in the pearl millet/soybean system before soybean seeding. When the capture of Solenopsis sp. was expressive, G. assimilis and L. villosa were less captured.
O objetivo deste trabalho foi o de avaliar populações de artrópodes-praga e de inimigos naturais presentes na superfície do solo em diferentes sistemas de semeadura direta da soja. No ano agrícola 2006/2007, em Dourados, MS, foi instalada uma área experimental com três condições de cobertura do solo: sorgo, milheto e vegetação espontânea, para semeadura posterior de soja. Quatro e duas avaliações, utilizando-se armadilhas pitfall, foram realizadas, respectivamente, no período de présemeadura e no período de desenvolvimento inicial da soja. Os dados foram analisados como medidas repetidas no tempo, com comparação posterior entre médias. A abundância e freqüência relativa foram calculadas para os dois períodos de avaliação. Gryllus assimilis (Orthoptera: Gryllidae) e Lagria villosa (Coleoptera: Lagriidae) foram as espécies de pragas mais abundantes, respectivamente, antes e após a semeadura. Solenopsis sp. (Hymenoptera: Formicidae) foi o inimigo natural mais abundante antes e após a semeadura. Os sistemas sorgo/soja e milheto/soja alteraram significativamente a densidade populacional dessas espécies e dos predadores Galerita collaris (Coleoptera: Carabidae) e Calosoma granulatum (Coleoptera: Carabidae). A espécie G. collaris acompanhou a dinâmica populacional de G. assimilis no sistema milheto/soja antes da semeadura. Quando a captura de Solenopsis sp. foi maior, G. assimilis e L. villosa foram menos capturados.

Researchers of different fields often need to learn and represent phenomena through relationships between variables and use them to predict the phenomena behavior under uncertain conditions. However, choosing the "best" model in a modeling exercise is always an arduous task, yet because of the various uncertainties associated with the modeling process.A way of obtaining a better prediction than it would be provided by a single model may be by combining a number of different model structures. Each model is adopted at a given observation with a probability that depends on the values of the explanatory variables for that observation. This is the logic under the mixture-of-experts model (MEM).The general MEM framework specifies that a prediction is made up of a series of predictions from separate models, or experts, each of them weighted by a quantity determined by a so called gating function.However, when building a MEM, many important decisions ought to be made, such as determining the number of clusters in to which the global data is to be sectioned and the clustering method to be adopted; the nature of the gating function applied; the criteria employed to elect the experts and the data set selected for performing validation, for example. Depending on how these decisions are made, different mixtures might be formed, providing different results.In the present study, we investigated the way such decisions affect the performance of the MEM, when this technique employs statistical models, applied to regression problems. The problem under analysis consists of estimating the municipal gross domestic product for the Brazilian states of Pará and Maranhão, as functions of municipal macroeconomic and demographic variables.

Ce travail consiste à préciser les caractéristiques du porc miniature "Pitman Moore" dans l'objectif d'une expérimentation animale destinée à tester des biomatériaux de comblement des lésions osseuses parodontales. A travers la littérature, puis de façon expérimentale, chez le porc conventionnel "Large White" et le porc miniature "Pitman Moore", les éléments suivants ont été étudiés : paramètres hématologiques, caryotype, formules dentaires, âge dentaire adulte, aspects cliniques, radiologiques et histologiques du parodonte. Le parodonte du "Pitman Moore" présente d'étroites similitudes structurales avec le parodonte humain. L'âge idéal d'expérimentation correspondant à l'âge dentaire adulte a été déterminé pour les races "Large White" et "Pitman Moore". Les secteurs préférenciels pour l'expérimentation parodontale ont été également déterminé en fonction de l'analogie avec les structures parodontales humaines et de l'accessibilité clinique et radiologique. L'ensemble de nos travaux permet de dire que le porc miniature "Pitman Moore" représente un modèle animal intéressant en parodontologie expérimentale.

Over the past two decades, cluster policies have become a standard instrument of
public authorities and economic development practitioners in many parts of the
world. This paper takes a critical stance on this phenomenon and provides
theoretical arguments that challenge the widespread application of cluster initiatives
to promote long-term regional development. We distinguish between and compare
two main bodies of thought: the neoclassical view and the agglomeration view. We
show that there are no rationales for cluster policy from the perspective of
neoclassical theory. The agglomeration view, in contrast, provides a convincing
conceptual basis for justifying economic policies implemented in form of cluster
initiatives. At the same time, however, it points to major problems related with the
cluster policy approach. We identify and elaborate on three essential difficulties, i.e.
the proper (1) targeting, (2) dosing, and (3) timing of cluster policy actions. We
highlight that the problems related with these fundamental issues of each public
initiative constitute powerful pitfalls and booby traps of cluster policies. (author's abstract)Series: SRE - Discussion Papers

The thesis deals with the topic of terminal value assessment in DCF models. Examining ten different techniques, the parameters behind, and the possible perils, its aim is to formulate the best practice for terminal value estimation. Afterwards, eleven of real business valuations are analyzed with the previously formulated best practice serving as a benchmark. Where possible, the impact of departures from the best practice on the estimated business value is quantified. The analysis confirms the hypothesis that practical terminal value assessments often diverge substantially from the best practice, which has a material impact on the resulting business value estimate.

I used two sampling techniques, visual line transects and pitfall traps, to compare the numbers and species richness of lizards in four vegetative communities representative of the Sonoran Desert region: exotic grasslands, native grasslands, oak woodlands and desertscrub. I found similar numbers of lizards and species richness in three of the four communities, but I detected more lizards using transects than pitfall traps in the oak woodland community. On a per area basis, I detected significantly more lizards with transects than with pitfall traps in all four communities (P = 0.018). I compared capture success using three different pitfall traps. Overall, I found no differences between capture success in black and white plastic 19-1 buckets (Chi square = 0.58, df = 1, P > 0.05) or between white buckets and number 10 cans stacked three deep (Chi square = 0.60, df = 1, P > 0.05). I did find that one species (Sceloporus magister) was captured more often in black buckets than in white buckets (Chi square = 5.33, df = 1, P < 0.05). Pitfall traps were significantly more expensive (P = 0.02) than transects in terms of materials, installation and data collection. I did not obtain sufficient recaptures of any species in the pitfall traps to generate population or survivorship estimates using the programs RELEASE, SURGE, or JOLLY. I calculated the effort necessary to obtain sufficient recaptures to make those estimates using pitfall traps. I also calculated the effort needed to obtain similar estimates using transects in each vegetative community. Recommendations for sampling days for the two methods varied considerably depending on the species and the vegetative community. If managers need mark-recapture data or detailed information on individual lizards, pitfall traps should be used. However, if managers do not need detailed information, I recommend using transects to sample lizard populations because they are less expensive, less time-consuming, and provide similar information on the relative abundance and species richness of lizard populations.

In the light of a market that showcases increased hesitation and skepticism over green marketing and environmental communication, is the necessity of a well executed corporate communication greater than ever. What can be seen on the market is corporations that are unintentionally using motive greenwashing as a tool for attracting and persuading consumers to favour the corporations image. Prior research within green marketing has put a large focus on greenwashing in product context and the effects of it on consumer behaviour. In this study greenwashing is examined in a communication context and its effect on different aspects of consumer behaviour and attitude.

Resumo: Scarabaeidae coprófagos têm grande importância econômica por removerem e enterrarem massas fecais bovinas em pastagens, melhorando as propriedades físicas e químicas do solo, além de serem agentes de controle biológico de parasitos de gado bovino. O objetivo desse experimento foi verificar se a irrigação de pastagem (com pivot central), especialmente na estação seca, influencia na abundância e riqueza em espécies de Scarabaeidae coprófagos, em comparação com um pasto não irrigado. O experimento foi realizado na Fazenda Santa Ofélia, Selvíria, estado do Mato Grosso do Sul, Brasil. Uma vez por semana foram feitas coletas de massas fecais de diferentes idades e armadilhas pitfall iscadas com massa fecal bovina, em áreas de pasto irrigado e não irrigado, no período de abril de 2004 a abril de 2005. Coletou-se 54854 besouros coprófagos, sendo as espécies mais abundantes: Labarrus pseudolividus, Nialaphodius nigrita, Ataenius aequalis, A. crenulatus, A. platensis, A. sculptor, A. scutellaris, Dichotomius bos, D. nisus, D. glaucus, Digitonthophagus gazella, Ontherus appendiculatus, Pedaridium bidens e Trichillum externepunctatum. Na estação chuvosa quase todas as espécies ocorreram em maior número no pasto não irrigado, com exceção de A. platensis, mas na estação seca duas espécies foram significantemente mais abundantes no pasto irrigado, L. pseudolividus e A. crenulatus. D. gazella, A. scutellaris, A. platensis, D. bos e D. glaucus foram capturados em quantidades similares em ambos os pastos. A partir dos resultados obtidos, conclui-se que a irrigação afetou negativamente a abundância de besouros coprófagos, especialmente na estação seca, talvez devido a fertilizantes adicionados à água de irrigação.
Abstract: Dung beetles are of great economic importance due to the removal and burial of dung pads in pastures, enhancing physical and chemical properties of the soil; in addition they are agents of biological control of cattle parasites. The objective of this experiment was to evaluate the influence of irrigation of a pasture by a central pivot, especially during the dry season, on the abundance and richness in species of dung beetles, when compared to a nonirrigated pasture. The experimental area was at Farm Santa Ofélia, located in Selvíria, state of Mato Grosso do Sul, Brazil. Collected cattle droppings of differents ages and pitfall traps were weekly baited with fresh dung pads, in an irrigated and a non-irrigated pasture, from April 2004 until April 2005. A total of 54,854 dung beetles were collected, where the most abundant species were Labarrus pseudolividus, Nialaphodius nigritas, Ataenius aequalis, A. crenulatus, A. platensis, A. sculptor, A. scutellaris, Dichotomius bos, D. nisus, D. glaucus, Digitonthophagus gazella, Ontherus appendiculatus, Pedaridium bidens and Trichillum externepunctatum. All species were most abundant during the rainy season. During the rainy season nearly all species were more abundant in the non-irrigated pasture, with A. platensis being the only exception, with larger numbers on the irrigated pasture. During the dry season two species, L. pseudolividus and A. crenulatus, were though more abundant in the irrigated pasture, while for D. gazella, A. scutellaris, A. platensis, D. bos and D. glaucus there were no statistically significant differences between pastures. Results show irrigation affected negatively the abundance of dung beetles, especially during the dry season. It is possible that the fertilizers added to the water used in the irrigation might have played a role in these results.

Market mechanisms for controlling pollution and other environmental problems, once considered experimental, have recently become favored tools for regulation, both in the U.S. and abroad. In the last several years, a $64 billion global market for carbon dioxide permits and offsets has emerged out of international deal-making on climate change. The carbon market has become a force to be reckoned with in international trade, and created many stakeholders with vested interests in the design of the market and its governing regulations. Driven by the international finance community and clamor from the general public for action on global warming, U.S. legislators are under increasing pressure to adopt similar measures. And as action by the U.S. seems more likely, industries that would likely be targeted by climate change legislation are becoming less obstructionist, increasingly seeking influence over the direction of regulation rather than attempting to block it altogether. Given current trends in business, finance and politics, it is likely that in the near future, the U.S. will adopt carbon pricing as a means to decrease carbon emissions and attempt to halt the progress of climate change. However, with so many stakeholders in the debate, designing the market will be a contentious and highly politicized process. Because of both scientific uncertainty and political factors, there is great potential for market failures, from miscounted emissions to perverse incentives to social inequity. This thesis examines some of the market designs that have been proposed, along with reasons why the carbon market is likely to fail to live up to its greatest promise.

The xerographic printing and copying industry has become extremely competitive. Xerox market share has gradually declined since the 1960s as the market share of corporations like Canon, Hewlett Packard and Ricoh has increased. In response to rising competition, various product architecture strategies are heralded as the means to gaining, or regaining, competitive advantage in this environment. Among the most popular of these strategies are platobrm strategy, product families and parts commonality, and outsourcing. The objective of this thesis is not to dispute the value of these strategies in the present context. Obviously, platform strategies and parts reuse enable firms to develop products faster and with less cost by leveraging previous investments. Likewise, in order to remain competitive in this environment, a firm can no longer afford to vertically integrate its products-clearly, firms can no longer afford to do everything themselves. Horizontal integration through outsourcing, or what Xerox calls extended enterprise, is therefore one source of competitive advantage. Platform strategy, parts reuse, and extended enterprise all make good sense but each of these strategies can easily backfire. In this paper we will examine these strategies and see how they relate to central themes in product architecture, such as, architectural modularity. Then we shall see how these strategies can, if not applied carefully, cause more problems than they attempt to resolve. Finally, in light of these problems, revised and more robust versions of these strategies are presented.

Récemment, des algorithmes spécifiques de discrimination sont implémentés dans les dispositifs actuels. Les pièges de la prise en charge des patients souffrant d'arythmie ne sont pas rares. Fréquemment, il s'agit d'érreurs de détection et de discrimination susceptibles de favoriser ou empirer l'arrythmie ou de déterminer des thérapies inappropriées tels que des chocs. En fait, la discrimination incorrecte des arythmies malignes pourrait avoir un impact significatif sur la morbidité et la mortalité. La meilleure gestion des arythmies devrait envisager des améliorations des algorithmes actuels des DAI propriétaires implantés dans la pratique cliniqueThe objective of my research was to investigate the manner in which clinical devices, such as ICDs and PMs, detect the most common arrhythmias encountered in clinical practice. Nowadays, specific algorithms of discrimination are implemented in current devices. The pitfalls in the management of patients with arrhythmias are not uncommon; most often these include errors in detection and discrimination which may promote and/or perpetuate the arrhythmia or determine inappropriate therapies such as shocks. In fact, the incorrect discrimination of malignant arrhythmias could have a significant impact on morbidity and mortality. The best management of arrhythmias should consider improvements of current algorithms of proprietary based ICDs implanted in the clinical practice

Scarabaeidae coprófagos têm grande importância econômica por removerem e enterrarem massas fecais bovinas em pastagens, melhorando as propriedades físicas e químicas do solo, além de serem agentes de controle biológico de parasitos de gado bovino. O objetivo desse experimento foi verificar se a irrigação de pastagem (com pivot central), especialmente na estação seca, influencia na abundância e riqueza em espécies de Scarabaeidae coprófagos, em comparação com um pasto não irrigado. O experimento foi realizado na Fazenda Santa Ofélia, Selvíria, estado do Mato Grosso do Sul, Brasil. Uma vez por semana foram feitas coletas de massas fecais de diferentes idades e armadilhas pitfall iscadas com massa fecal bovina, em áreas de pasto irrigado e não irrigado, no período de abril de 2004 a abril de 2005. Coletou-se 54854 besouros coprófagos, sendo as espécies mais abundantes: Labarrus pseudolividus, Nialaphodius nigrita, Ataenius aequalis, A. crenulatus, A. platensis, A. sculptor, A. scutellaris, Dichotomius bos, D. nisus, D. glaucus, Digitonthophagus gazella, Ontherus appendiculatus, Pedaridium bidens e Trichillum externepunctatum. Na estação chuvosa quase todas as espécies ocorreram em maior número no pasto não irrigado, com exceção de A. platensis, mas na estação seca duas espécies foram significantemente mais abundantes no pasto irrigado, L. pseudolividus e A. crenulatus. D. gazella, A. scutellaris, A. platensis, D. bos e D. glaucus foram capturados em quantidades similares em ambos os pastos. A partir dos resultados obtidos, conclui-se que a irrigação afetou negativamente a abundância de besouros coprófagos, especialmente na estação seca, talvez devido a fertilizantes adicionados à água de irrigação.
Dung beetles are of great economic importance due to the removal and burial of dung pads in pastures, enhancing physical and chemical properties of the soil; in addition they are agents of biological control of cattle parasites. The objective of this experiment was to evaluate the influence of irrigation of a pasture by a central pivot, especially during the dry season, on the abundance and richness in species of dung beetles, when compared to a nonirrigated pasture. The experimental area was at Farm Santa Ofélia, located in Selvíria, state of Mato Grosso do Sul, Brazil. Collected cattle droppings of differents ages and pitfall traps were weekly baited with fresh dung pads, in an irrigated and a non-irrigated pasture, from April 2004 until April 2005. A total of 54,854 dung beetles were collected, where the most abundant species were Labarrus pseudolividus, Nialaphodius nigritas, Ataenius aequalis, A. crenulatus, A. platensis, A. sculptor, A. scutellaris, Dichotomius bos, D. nisus, D. glaucus, Digitonthophagus gazella, Ontherus appendiculatus, Pedaridium bidens and Trichillum externepunctatum. All species were most abundant during the rainy season. During the rainy season nearly all species were more abundant in the non-irrigated pasture, with A. platensis being the only exception, with larger numbers on the irrigated pasture. During the dry season two species, L. pseudolividus and A. crenulatus, were though more abundant in the irrigated pasture, while for D. gazella, A. scutellaris, A. platensis, D. bos and D. glaucus there were no statistically significant differences between pastures. Results show irrigation affected negatively the abundance of dung beetles, especially during the dry season. It is possible that the fertilizers added to the water used in the irrigation might have played a role in these results.

Organisations have spent billions of dollars (USD) on investments in data warehouses. Many have succeeded, but many have also failed. These failures are considered mostly to be of an organisational nature and not of a technological, as one might have expected. Due to the failures, organisations have problems to derive business value from their data warehouse investments. Obtaining business value from data warehouses is necessary, since the investment is of such a magnitude that it is clearly visible in the balance sheet. In order to investigate how the business value may be increased, we have conducted an extensive literature study, aimed at identifying opportunities and future directions, which may alleviate the problem of low return on investment. To balance the work, we have also identified pitfalls, which may hinder organisations to derive business value from their data warehouses.
Based on the literature survey, we have identified and motivated possible research areas, which we consider relevant if organisations are to derive real business value from their data warehouses. These areas are:
* Integrating data warehouses in knowledge management.
* Data warehouses as a foundation for information data super stores.
* Using data warehouses to predict the need for business change.
* Aligning data warehouses and business processes.
As the areas are rather broad, we have also included examples of more specific research problems, within each possible research area. Furthermore, we have given initial ideas regarding how to investigate those specific research problems.

In recent years, increased demands have been placed on hydrologists to find the most effective methods of making predictions of hydrologic variables in ungauged basins. A huge part of the southern African region is ungauged and, in gauged basins, the extent to which observed flows represent natural flows is unknown, given unquantified upstream activities. The need to exploit water resources for social and economic development, considered in the light of water scarcity forecasts for the region, makes the reliable quantification of water resources a priority. Contemporary approaches to the problem of hydrological prediction in ungauged basins in the region have relied heavily on calibration against a limited gauged streamflow database and somewhat subjective parameter regionalizations using areas of assumed hydrological similarity. The reliance of these approaches on limited historical records, often of dubious quality, introduces uncertainty in water resources decisions. Thus, it is necessary to develop methods of estimating model parameters that are less reliant on calibration. This thesis addresses the question of whether physical basin properties and the role they play in runoff generation processes can be used directly in the estimation of parameter values of the Pitman monthly rainfall-runoff model. A physically-based approach to estimating the soil moisture accounting and runoff parameters of a conceptual, monthly time-step rainfall-runoff model is proposed. The study investigates the physical meaning of the model parameters, establishes linkages between parameter values and basin physical properties and develops relationships and equations for estimating the parameters taking into account the spatial and temporal scales used in typical model applications. The estimationmethods are then tested in selected gauged basins in southern Africa and the results of model simulations evaluated against historical observed flows. The results of 71 basins chosen from the southern African region suggest that it is possible to directly estimate hydrologically relevant parameters for the Pitman model from physical basin attributes. For South Africa, the statistical and visual fit of the simulations using the revised parameters were at least as good as the current regional sets, albeit the parameter sets being different. In the other countries where no regionalized parameter sets currently exist, simulations were equally good. The availability, within the southern African region, of the appropriate physical basin data and the disparities in the spatial scales and the levels of detail of the data currently available were identified as potential sources of uncertainty. GIS and remote sensing technologies and a widespread use of this revised approach are expected to facilitate access to these data.

Includes bibliographical references.ISO 14001's increasing importance in trade considerations and growing status within regulatory policies means that eventually, few organizations of any size and in any country will be able to ignore it. But does the standard discriminate against the Developing World? Is it accurate to measure the success a country has had in implementing ISO 14001 without taking its size and wealth into account? Are critics of the standard missing the point? This paper examines these questions from the South African perspective and proposes a new method to measure the extent of ISO 14001 acceptance between countries of differing population and economic output.

Although many information system (IS) implementations are considered to have the resources necessary to be successful, they often fail. This is especially challenging for small IS providers who lack a proven process for gaining willingness to use and onboard a new customer. Hence, there is a need to develop a framework to identify potential pitfalls in such implementation matters, from designing the system until successfully onboarded customers. This paper aims to target this issue and proposes a framework for identifying common pitfalls during the implementation process of an IT system. Moreover, this paper applies the framework to an IS provider in the start-up phase by focusing on the system user. With the support of the framework and based on the company's context, this paper presents identified pitfalls and suggestions for actions that the IS provider can take to avoid them. IS models are selected and applied considering the company's needs and previous literature. The IS models considered are Value Network Analysis (VNA), Extended Technology Acceptance Model (TAM2), and Theory of Planned Behavior (TPB). As a result, seven pitfalls are identified considering organizational culture and leading change, user resistance, complexity, mandatory reliance, value demonstration, experience and control, and weak links.
