Automobile use is associated with significant problems such as air pollution and obesity. Decisions to use the automobile or its alternatives, including walk, bicycle, and public transit, are believed to be associated with urban form. However, in contrast to the hypothesis that compact urban form significantly reduces automobile travel, previous studies reported only a modest effect on travel behavior. These studies, largely built on microeconomic utility theory, are not sufficient for assessing the effect of compactness, for several reasons: (1) The studies postulate that travel invokes only disutility, but travel may also provide intrinsic utility or benefits insomuch as people travel for its own sake; (2) the studies have traditionally focused on how urban compactness reduces the distance between trip origin and destination and accordingly reduces trip time, but urban compactness also increases congestion and reduces trip speed, and thus increases trip time; and (3) the studies have mostly examined automobile commuting, but people travel for various purposes, using different travel modes, and the impact of urban compactness on the utility of non-automobile non-commuting travel has not been duly examined. On this ground, to better explain the effects that urban compactness has on travel behavior, this dissertation refines the concept of travel utility using two additions to the microeconomic utility theory: activity-based utility theory of derived travel demand and approaches to positive utility of travel. Accordingly, it designs a conceptual model that specifies travel utility as an intermediary between urban compactness and travel behavior and examines the behavior associated with and utility derived from travel mode choices for alternative purposes of travel. Twenty individual models are derived from the conceptual model and tested within the context of Seoul, Korea, using a confirmatory approach of structural equation modeling and data from geographic information systems and a structured sample survey, which is initially designed and validated by semi-structured interviews and subsequent statistical tests. By comparing the individual models, this research concludes that the urban compactness effect on travel behavior, represented by trip frequencies and supplemented by mode shares, is better explained when travel utility is considered and if travel purposes are separately examined. Major empirical findings are that urban compactness affects travel behavior mainly by increasing the benefits of travel in comparison to its modest effect on the cost reduction and people’s behavioral response to urban compactness is to shift modes of commuting travel, decrease travel for shopping, and increase travel for leisure. These purpose-specific findings have implications for transportation planners and public health planners by assisting them in linking plans and policies concerning urban compactness to travel purposes.

在都市發展環境當中，居住環境品質取決於居住者本身之感受程度，可分為內部環境及外部空間結構，內部環境係指針對居住者本身所在的生活圈裡，外部空間結構則多半為公共設施的鄰近程度、交通便利性及嫌惡設施等因素，世界衛生組織曾於1961年世界衛生報告中提出理想居住環境為安全性、健康性、便利性、舒適性等基本理念，經由探索性、驗證性因素，分析彙整出解釋社區居民對居住環境品質之衡量著力點在於實體性、社區服務與管理、現代化等三大方面，因此居民感受度是與前開四種基本理念相呼應的。 在針對居住環境品質與社區滿意度相關文獻探討後發現，居住環境品質多與社區滿意度有關聯，顯示在建構生活品質模式應先將領域分群，透過客觀、認知及評估因子，即可呈現各領域的滿意度。 為解決公共設施保留地取得、歷史建築物保存及公共開放空間之提供等議題，我國開始實施容積移轉制度，主要目的為追求環境寧適、健全實質建設、保留彈性立法規則及民眾參與，惟接受基地在注入原基準容積後，其鄰近居民之居住環境品質是否受到影響及衝擊，為本研究所關注之重點；本研究係探討容積移轉制度實行迄今，接受基地容積移轉案件在興建完成後，對週邊土地所帶來之影響。 本研究以容積移轉接受基地興建前後對居住環境品質之問卷調查，以新北市中和地區之接受基地周邊住民作為受訪對象，以因素分析、結構方程模式為分析方法，以五大變數－接受基地興建前既有環境滿意度、接受基地興建後正面環境改善、接受基地興建後負面改變影響、容積移轉政策修正建議及其政策滿意度進行模式驗證；研究結果發現既有環境滿意度對負面改變影響、政策修正建議呈正向影響，對正面環境改善、政策滿意度呈負向影響，另負面改變影響、政策修正建議則具有著之中介效果，該研究可作為未來推動容積移轉制度辦理之修正建議。 / In the urban development environment, living environment quality depends on how residents feel. It can be divided into internal and external spatial structure environments. The internal environment refers to living areas where the residents themselves reside; the external spatial structures are mostly the proximity, accessibility and distaste factors of public facilities. The World Health Organization’s 1961 World Health Report proposed the basic concept of the ideal living environment for safety, health, convenience, comfort, etc. They compiled an analysis of the environmental community to explain the measure of the quality of living through exploratory, confirmatory factors. The analysis compiled an explanation of the way community residents measure environmental quality. The focal point lies in the three aspects of modernization: physical properties, community service and management. Therefore residents' susceptibility echoes the former four basic philosophies. In regards to the quality of living environment and community satisfaction, after disscussing relevant literature, we found that the quality of living environment correlate with community satisfaction interaction. This shows that during the construction of life quality models, domain clustering should first take place, then go through the analysis of objective factors, perceived factors, evaluated factors before presenting various domains of satisfaction. However, to address topics on land reserved for the public infrastructure, topics on historical building preservation and public open space topics, Taiwan began to implement transferable development rights control. The main goal of this system was to pursue environmental quality, improve substantive construction, maintain the flexibility of legislative rules and promote public participation. However, the main concern of this study is whether or not the environmental living quality of nearby residents' was affected after the development rights of the receiving area received incremental development rights and built high-rise buildings. This study mainly dicusses ways to implement the so far accepted transferable development rights case after construction is complete, and the effects brought on by the surrounding land. This study looks at environmental quality before and after transferable development rights acceptance and construction. A questionnaire was designed for this study and was administered to local residents of the Zhong-he, New Taipei City development rights receiving area as target respondents. This study was conducted by way of factor analysis and structural equation modeling analysis. Five variables were proposed, which are variables of nearby residents of the development rights receiving area regarding environmental satisfaction before construction; variables of nearby residents having positive evaluation after construction; variables of nearby residents having negative evaluation after construction; variables of nearby residents regarding transferable development rights policy amendment; variables of nearby residents regarding transferable development rights policy satisfaction, to conduct a model confirmatory. The results show that environmental satisfaction variables have a positive impact on negative evaluation variables and policy amendment variables, but have a negative impact on positive evaluation variables and policy satisfaction. In addition, negative evaluation variables have indirect effects on policy amendments. This study can be used as a reference for the implementation of the transferable development rights system in handling amendments in the future.

Thesis (PhD)--Macquarie University, Macquarie Graduate School of Management, 2006. / Bibliography: p. 253-276. / Introduction -- Knowledge and knowledge management systems -- Towards a measurement model of KMS success -- Research methodology -- Data analyses and results -- Conclusions and implications. / Knowledge management is becoming pervasive in organizations. Information technology (IT) has been widely used in organizational knowledge management initiatives, and organizations continue to invest in IT expecting that its use will improve knowledge workers' productivity and organizational performance. -- Knowledge management systems (KMS) are information technology applications designed for knowledge management. The pervasive use of KMS in organizations has raised crucial concerns about the use and value of KMS, which can be expressed as two key questions: - What are the key determinants to the users' acceptance and use of KMS in their daily work? - What is the actual role of KMS in the support of knowledge management? -- For this thesis, empirical research was conducted on KMS success in organizations from a social capital perspective, aiming to tackle these critical questions. Based on a review of existing studies on knowledge management and information systems success, two KMS research models are developed, namely a Socio-Technical System Framework of KMS and an Adaptive Structuration Theory (AST)-based KMS Success Model. The socio-technical framework model of KMS sets out the main KMS components and the interrelationships between these components, presenting a systematic view of KMS in organizations. The AST-based KMS success model represents dynamic and evolutionary KMS in organizations, proposing a system-to-value chain of KMS success linking KMS use to social capital, and to intellectual capital. In the research, the two models have been operationalized; consequently, a set of theoretical hypotheses has been derived. -- A set of survey instruments has been developed or adapted for the study. A preliminary study is used to test, adapt, and modify the new instruments. A web-based cross-sectional survey is conducted, and a sample of 362 knowledge workers from a variety of organizations enables the researcher to further validate the new instruments, assess the research models, and test the hypothesized relationships through structural equation modeling techniques (PLS and LISREL). The results provide clear evidence of the newly developed instruments' reliability, validity, and general applicability, and demonstrate that the research models have good explanatory power for the variances in the KMS use and social capital constructs. Significantly, the study has confirmed that KMS does have the expected significant positive effects on individual social capital development, a critical social infrastructure for knowledge management. The significant positive impacts of KMS use on three dimensions of social capital-structural, relational, and cognitive dimension-have been assessed, and significant findings have been achieved. Moreover, a set of potential critical determinants to users' acceptance and use of KMS has also been assessed in the study. The results have demonstrated the different levels of impacts of these factors on the users' acceptance and use of KMS. -- Based on the research results, recommendations are made for managers, and implications have been drawn for future research. -- Keywords: Knowledge Management Systems (KMS), KMS success measurement, performance-related use of KMS, structural equation modeling, social capital. / Mode of access: World Wide Web. / ix, 277, A23 p. ill

[pt] Dado o surgimento de uma nova ordem econômica, as empresas em todo o mundo perceberam que precisam estar comprometidas com a sustentabilidade. As pressões externas vão desde o governo, com a criação de regulamentações socioambientais, até os empregados e a sociedade - mídia, ONGs e clientes - que estão cada vez mais conectados, atentos e exigentes a essas questões. Empresas sustentáveis devem satisfazer as necessidades do presente (gerar lucro) sem comprometer o futuro (respeitando o meio ambiente e os preceitos de responsabilidade social). A indústria de manufatura, foco dessa dissertação, tem muito a contribuir para a sustentabilidade, pois impacta socio-economico-ambientalmente os locais onde opera, de forma significativa. Geração de gases de efeito estufa e de resíduos tóxicos estão entre os grandes vilões, mas não se limitando a eles. No âmbito interno, as empresas necessitam absorver o conceito de sustentabilidade no seu processo de produção, a partir de práticas de gestão ambiental relacionadas, por exemplo, à otimização do uso dos recursos ambientais (ex. reuso de água e utilização de energias alternativas), à redução de gases poluentes e às alternativas para descarte de resíduos; assim como às práticas de gestão social tais como medidas para aumentar saúde e segurança no ambiente de trabalho e criação de programas ligados ao bem estar dos funcionários. As ações, porém, devem ser ampliadas para toda a cadeia do processo e devem ser adotadas medidas colaborativas com os fornecedores para que sejam comprometidos e também responsáveis. No entanto, para a empresa se tornar sustentável, investimentos adicionais e aumento de custos são necessários para incluir em sua estrutura pessoal e processos responsáveis pelo incremento da sustentabilidade, seja ela econômica, social ou relacionada ao meio ambiente, o chamado triple bottom line, em inglês. / [en] Companies worldwide realized that being committed to sustainability is becoming a source to competitive advantage. Empirical evidence exists in the literature validating a positive link of sustainable manufacturing practices with organizational performance. However, there is a lack of rigorous empirical studies directly examining the impact of both environmental and social practices on operational manufacturing performance, especially in four main competitive operational capabilities: cost delivery, quality, and flexibility. This study analyses these relationships with literature review and the backdrop of the resource-based view and of the natural resource-based view of the firm. For this purpose, structural equation modeling (SEM) is used to build the measurement model and hierarchical stepwise multiple regression is used to test the research hypotheses. The data used were obtained from the sixth round of the International Manufacturing Strategy Survey (IMSS-VI) which includes responses from 931 manufacturing plants within the assembly industry in 22 countries. Our findings suggest that internal and external sustainability management practices are complementary. Manufacturing plants can increase their quality and flexibility performance, by implementing internal sustainable practices, such as water and energy consumption reduction, environmental and social certifications, work/life balance policies and sustainability communication, and can increase their cost efficiency and delivery performance by promoting supplier s sustainability management. Overall, this study contributes to the investigation of strategies for sustainable management, highlighting important implications for both practice and future research.

From the marketing point of view, building a significant green market can be of great importance in facing this challenge. Considering that, understanding the backgrounds of ecological consumption could reveal how environmentally oriented consumption behavior occur and so, it can help the development of both educational and commercial campaigns. The present study examines the influence of emotional and cognitive factors in the ecologically correct shopping behavior. To do so, a conceptual model was built, based on the literature and it was submitted to empirical verification, using a survey approach, analysed through Structural Equation Modeling (SEM) method. A sample of 291 individuals, gathered through electronic means was analysed during the month of January, 2010. This research's findings confirm that emotion and subjective knowledge are backgrounds for ecologically correct consumption, mediated by the attitude reffering to the ecological consumption and by the intention to engage in such behavior. It is considered that the objectives of the present study, which was to identify the backgrounds of ecological consumption, were achieved. / O desenvolvimento sustentável é um desafio multidimensional com implicações para todos os setores da sociedade. Do ponto de vista do marketing, a construção de um mercado verde significativo pode ser de grande importância neste desafio. Diante disto, compreender os antecedentes do consumo ecológico lança luz sobre como se dão os comportamentos de consumo ambientalmente orientados, o que pode auxiliar no desenvolvimento de campanhas tanto educativas quanto comerciais. O presente estudo examina a influência de fatores emocionais e cognitivos nos comportamentos de compra ecológica. Para isso, um modelo conceitual foi construído a partir da literatura e submetido à verificação empírica, utilizandose levantamento para coleta de dados e Modelagem de Equações Estruturais para análise. Foi analisada uma amostra de 291 respondentes, levantada por meio eletrônico durante o mês de janeiro de 2010. Os achados desta pesquisa confirmam a emoção e o conhecimento subjetivo como antecedentes do consumo ecológico, mediadas pela atitude referente ao consumo ecológico e pela intenção de se engajar em tal comportamento. Sugestões de pesquisa futura são analisadas com base na teoria de marketing.

We investigate possible usage of Errors-in-Variables estimator (EIV), when esti- mating structural equations models (SEM). Structural equations modelling pro- vides framework for analysing complex relations among set of random variables where for example the response variable in one equation plays role of the predic- tor in another equation. First an overview of SEM and some common covariance based estimators is provided. Special case of linear regression model is investi- gated, showing that the covariance based estimators yield the same results as ordinary least squares. A compact review of EIV models follows, Errors-in-Variables models are re- gression models where not only response but also predictors are assumed to be measured with an error. Main contribution of this paper then lies in defining modifications of the EIV estimator to fit in the SEM framework. General opti- mization problem to estimate the parameters of structural equations model with errors-in-variables si postulated. Several modifications of two stage least squares are also proposed for future research. Equation-wise Errors-in-Variables estimator is proposed to estimate the coeffi- cients of structural equations model. The coefficients of every structural equation are estimated separately using EIV estimator. Some theoretical conditions...

In this sense, we note that the inter organizational information sharing has been pointed out in several studies (e.g., LEE et al, 2012; GIUNIPERO and ELTANTAWY , 2004; BLACKHURST et al, 2011) as an element capable of mitigating several risks involved in the productive activities of a supply chain. This thesis fits into this perspective, more specifically, seeks to analyze the relationship between sharing information with suppliers and customers and the mitigation of risks in supply chains (i.e. disruptions, poor delivery performance, failure orders, poor demand forescast, and others). Moreover, it is expected to understand if this fact (risk mitigation) contribute to improving business performance. Thus, we performed an empirical study consists of three stages, namely: i) literature review, ii) conducting a test of hypotheses with data processing by means of the technique of Structural Equation Modeling, and iii) interviews for in-depth understanding of the hypotheses were confirmed. Overall, the results indicate that, for the studied sector, a share of effective and efficient information between the company and its key suppliers focus promotes the mitigation of supply disruptions and inefficiencies in distribution operations or fulfilling delivery times along the chain, even without an appropriate sharing of information on demand (by the closest ties of the final consumer) or occurring inconsistencies with regard to its prediction. Moreover, with respect to performance improvement from the risk mitigation, the results are conclusive and allow to state that the expected effect was confirmed, i.e., so smaller are the risks involving the activities of supply, production and distribution of a focal with its suppliers and customers, best will their performance results (operational , market and financial). As contribution of the study, besides to filling the gaps identified in the literature highlights the production of knowledge to data from the Brazilian situation, since this research focuses on a recent topic (risks mitigation in supply chains) in an industry specific, of agri-companies. / Estudos mostram que se os riscos de uma cadeia de suprimentos não forem mitigados, estes podem afetar a eficiência dos fluxos de produtos, serviços e informações da mesma, provocando o desalinhamento entre as atividades, ineficiência nas operações e o baixo desempenho das empresas. Sob esta perspectiva, o compartilhamento inter organizacional de informações tem sido apontado em diversos estudos (por exemplo, GIUNIPERO e ELTANTAWY, 2004; BLACKHURST et al., 2011; LEE et al., 2012) como um elemento capaz de mitigar boa parte dos riscos que envolvem as atividades produtivas de uma cadeia de suprimentos. Há, entretanto, uma lacuna na literatura no que diz respeito aos efeitos do compartilhamento de informações sobre a mitigação de riscos envolvendo o fornecimento e a demanda. Sendo assim, a presente tese busca analisar a relação existente entre o compartilhamento de informações e a mitigação de riscos envolvendo o fornecimento (ou seja, interrupções, ineficiências nas operações de distribuição ou no cumprimento de prazos de entrega) e demanda (a saber, colocações repentinas de pedidos, decorrentes de alterações repentinas e frequentes na demanda ou ocasionadas por erros nas projeções de demanda dos principais clientes frente à sua demanda real). Além disso, buscou-se entender se a redução de riscos envolvendo o fornecimento e a demanda pode contribuir para a melhoria de desempenho empresarial. Para tanto, realizou-se um estudo empírico composto de três etapas, a saber: i) revisão de literatura; ii) realização de um teste de hipóteses com tratamento dos dados por meio da técnica de Modelagem de Equações Estruturais, e; iii) entrevistas para entendimento em profundidade das hipóteses que foram confirmadas. De maneira geral, os resultados permitem concluir que, para o setor pesquisado, um compartilhamento de informações eficaz e eficiente entre a empresa foco e seus principais fornecedores promove a mitigação de interrupções no fornecimento, bem como a redução de ineficiências nas operações de distribuição ou no cumprimento de prazos de entrega ao longo da cadeia. Sob esta perspectiva nota-se que tal mitigação ocorre mesmo sem haver um compartilhamento adequado de informações sobre a demanda (por parte dos elos mais próximos do consumidor final) ou ocorrendo inconsistências no que diz respeito à sua previsão. Com relação à melhoria de desempenho a partir da mitigação de riscos, os resultados obtidos são contundentes e permitem afirmar, sem ressalvas, que o efeito esperado foi confirmado, ou seja, quanto menores forem os riscos envolvendo as atividades de suprimentos, produção e distribuição de uma empresa focal com seus fornecedores e clientes, melhores serão os seus resultados de desempenho (operacional, de mercado e financeiro). Como contribuição do estudo, além do preenchimento das lacunas identificadas na literatura destaca-se a produção de conhecimento com dados da situação brasileira, uma vez que esta pesquisa foca um tema recente e pouco pesquisado (gestão de riscos em cadeias de suprimentos) em um setor específico, o de empresas agroindustriais.

Este trabalho aborda a estretégia de retenção de clientes por meio da prática do marketing de relacionamento no contexto do varejo e serviços de uma concessionária de veículos. Mais especificamente, a Passion Automóveis Ltda., concessionária da marca Peugeot, para as cidades de Bento Gonçalves/RS e Caxias do Sul/RS. O modelo teórico proposto por Sirdeshmukh, Singh e Sabol (2002) e suas respectivas hipóteses é utilizado para verificar o entendimento das práticas e comportamentos confiáveis percebidos nos prestadores de serviços e que constroem ou exaurem a confiança do consumidor e os mecanismos para converter a confiança do consumidor em termos de valor e lealdade em trocas relacionais. Para tanto, utilizou-se de uma amostra estratificada da população de pesquisa que totalizou 235 respondentes, e os dados foram coletados através de três formas de pesquisas: (i) entrevista por telefone assistida por computador; (ii) survey por correspondência; e (iii) survey eletrônica. O modelo utilizado (i) apresenta uma conceituação multidimensional para a construção de confiança; (ii) incorpora duas facetas distintas de confiança do consumidor, ou seja, os funcionários da linha de frente e as políticas e práticas gerenciais; e (iii) especifica o valor como um mediador entre a confiança e a lealdade nos relacionamentos. Os dados foram avaliados através da análise de estatística multivariada de dados, utilizando a técnica de Modelagem de Equações Estruturais, e os resultados apóiam uma visão tri-dimensional das avaliações da confiança ao longo da competência operacional, da benevolência operacional e da orientação para solução de problemas. Além disso, foi encontrado evidências de contingente relações assimétricas entre as dimensões de confiabilidade na confiança dos consumidores. Para as políticas e práticas gerenciais, benevolentes práticas demonstraram um efeito de "negatividade" dominante (isto é, uma unidade de desempenho negativa tem um efeito mais forte do que uma unidade de desempenho positivo), para o pessoal de linha de frente, comportamentos orientados para solução de problemas do consumidor demonstraram um efeito de "positividade" dominante. O valor teve suporte estatístico para mediar parcialmente às facetas da confiança e a lealdade do consumidor. A faceta da confiança no pessoa de linha de frente teve um papel crítico em relação à faceta da confiança nas políticas e práticas gerenciais na lealdade do consumidor, evidenciando a confiança como unidimensional como antecedente da lealdade. / Submitted by Marcelo Teixeira (mvteixeira@ucs.br) on 2014-06-03T17:39:03Z No. of bitstreams: 1 Dissertacao Lasier Gorziza de Souza.pdf: 3156048 bytes, checksum: 396c12085f2317907ff40f8a7b582f2d (MD5) / Made available in DSpace on 2014-06-03T17:39:03Z (GMT).

More specifically, the Passion Automóveis Ltda., Peugeot concessionaire for the cities of Bento Gonçalves/RS and Caxias do Sul/RS. The proposed framework by Sirdeshmukh, Singh and Sabol (2002) and their assumptions are used to check the understanding of practices and behaviors perceived to reliable service and that build or deplete consumer trust and the mechanisms to convert trust consumer in terms of value and loyalty in relational exchanges. To this end, we used a stratified sample of the population reserach which totaled 235 respondents, and data were collected from three types of searches: (i) telephone interview, computer-assisted, (ii) a survey by mail, and (iii) electronic survey. The model used (i) uses a multidimensional conceptualization for the trustworthiness construct; (ii) incorporates two distinct facets of consumer trust, namely, frontline employees and management policies and practices; and (iii) specifies value as a key mediator of the trust-loyalty relationship. The data were evaluated by analysis of multivariate data, using the technique of Structural Equation Modeling, and the results support a tripartide view of trustworthiness evaluations along operational competence, operational benevolence, and problem-solving orientation dimensions. Moreover, these works find evidence of contingent asymmetric relationship between trustworthiness dimension and consumer trust. For management policies and practices, benevolent behaviors demonstrate a dominant "negativity" effect (i.e., a unit negative performance has a stronger effect than a unit positive performance), for front-line employees, behavior oriented for problem-solving consumer demonstrated an effect of "positive" ruling. The value have statistical support to partially mediate the facets of trust in on consumer loyalty. The aspect of confidence in the personal front line played a critical role in relation to the aspect of trust policies and management practices in loyalty, showing the trust as one-dimensional as an antecedent of loyalty.

The use of Information Technology (IT) has been a tool increasingly used in reaching that goal. Thus, it has become an important issue in public organizations, particularly in institutions of higher education, determine which factors influence the acceptance and use of technology, impacting on the success of its implementation and the desired organizational results. The Technology Acceptance Model - TAM was used as the basis for this study and is based on the constructs perceived usefulness and perceived ease of use. However, when it comes to integrated management systems due to the complexity of its implementation,organizational factors were added to thus seek further explanation of the acceptance of such systems. Thus, added to the model five TAM constructs related to critical success factors in implementing ERP systems, they are: support of top management, communication, training, cooperation, and technological complexity (BUENO and SALMERON, 2008). Based on the foregoing, launches the following research problem: What factors influence the acceptance and use of SIE / module academic at the Federal University of Para, from the users' perception of teachers and technicians? The purpose of this study was to identify the influence of organizational factors, and behavioral antecedents of behavioral intention to use the SIE / module academic UFPA in the perspective of teachers and technical users. This is applied research, exploratory and descriptive, quantitative with the implementation of a survey, and data collection occurred through a structured questionnaire applied to a sample of 229 teachers and 30 technical and administrative staff. Data analysis was carried out through descriptive statistics and structural equation modeling with the technique of partial least squares (PLS). Effected primarily to assess the measurement model, which were verified reliability, convergent and discriminant validity for all indicators and constructs. Then the structural model was analyzed using the bootstrap resampling technique like. In assessing statistical significance, all hypotheses were supported. The coefficient of determination (R ?) was high or average in five of the six endogenous variables, so the model explains 47.3% of the variation in behavioral intention. It is noteworthy that among the antecedents of behavioral intention (BI) analyzed in this study, perceived usefulness is the variable that has a greater effect on behavioral intention, followed by ease of use (PEU) and attitude (AT). Among the organizational aspects (critical success factors) studied technological complexity (TC) and training (ERT) were those with greatest effect on behavioral intention to use, although these effects were lower than those produced by behavioral factors (originating from TAM). It is pointed out further that the support of senior management (TMS) showed, among all variables, the least effect on the intention to use (BI) and was followed by communications (COM) and cooperation (CO), which exert a low effect on behavioral intention (BI). Therefore, as other studies on the TAM constructs were adequate for the present research. Thus, the study contributed towards proving evidence that the Technology Acceptance Model can be applied to predict the acceptance of integrated management systems, even in public. Keywords: Technology / Nas ?ltimas d?cadas o setor p?blico vem sofrendo press?es com vistas a melhorar seu desempenho. A utiliza??o da Tecnologia da Informa??o (TI) tem sido uma ferramenta cada vez mais empregada na tentativa de alcan?ar esse objetivo. Dessa forma, passou a ser uma importante quest?o nas organiza??es p?blicas, e em particular nas institui??es de ensino superior, verificar quais fatores influenciam a aceita??o e o uso da tecnologia, impactando no sucesso de sua implementa??o e nos resultados organizacionais almejados. O Modelo de Aceita??o da Tecnologia TAM foi utilizado como base para o presente estudo e fundamenta-se nos construtos utilidade percebida e facilidade de uso percebida. No entanto, quando se trata de sistemas integrados de gest?o, devido ? complexidade de sua implanta??o, acrescentaram-se fatores organizacionais para assim buscar maior explica??o da aceita??o desses sistemas. Assim, acrescentaram-se ao modelo TAM cinco construtos relacionados aos fatores cr?ticos de sucesso na implementa??o de sistemas ERP, s?o eles: apoio da alta administra??o, comunica??o, treinamento, coopera??o, e complexidade tecnol?gica (BUENO e SALMERON, 2008). Com base no exposto, lan?a-se o seguinte problema de pesquisa: quais fatores influenciam a aceita??o e uso do SIE/m?dulo acad?mico na Universidade Federal do Par?, a partir da percep??o dos usu?rios t?cnicos e docentes? O objetivo geral da pesquisa foi identificar a influ?ncia de fatores organizacionais e comportamentais como antecedentes da inten??o comportamental de uso do SIE/m?dulo acad?mico na UFPA sob a perspectiva dos usu?rios docentes e t?cnicos. A presente pesquisa ? aplicada, explorat?ria e descritiva, de natureza quantitativa com a aplica??o de um survey, e a coleta de dados se deu por meio de question?rio estruturado aplicado a uma amostra composta por 229 docentes e 30 t?cnico-administrativos. A an?lise de dados se deu atrav?s de estat?sticas descritivas e modelagem de equa??o estrutural com a t?cnica de m?nimos quadros parciais (Partial Least Square-PLS). Primeiramente efetuou-se a avalia??o do modelo de mensura??o, no qual foram verificadas a confiabilidade, validade convergente e discriminante para todos os indicadores e construtos. Em seguida, o modelo estrutural foi analisado, com a utiliza??o de bootstrap como t?cnica de reamostragem. Na avalia??o das signific?ncias estat?sticas, todas as hip?teses formuladas foram suportadas. O coeficiente de determina??o (R?) foi considerado alto ou m?dio em 5 das 6 vari?veis end?genas, assim o modelo consegue explicar 47,3% da varia??o da inten??o comportamental. Ressalta-se que, dentre os antecedentes da inten??o comportamental (BI) analisados no presente estudo, utilidade percebida ? a vari?vel que possui maior efeito sobre a inten??o comportamental, seguida pela facilidade de uso (PEU) e a atitude (AT). Dentre os aspectos organizacionais (fatores cr?ticos de sucesso) estudados, complexidade tecnol?gica (TC) e treinamento (TRE) foram aqueles com maior efeito sobre a inten??o comportamental de usar, apesar desses efeitos serem inferiores aos produzidos pelos fatores comportamentais (origin?rios do TAM). Destaca-se, ainda, que o apoio da alta administra??o (TMS) apresentou, entre todas as vari?veis, o menor efeito sobre a inten??o de usar (BI) e foi seguida pela comunica??o (COM) e coopera??o (CO), as quais exercem um baixo efeito sobre a inten??o comportamental (BI). Portanto, conforme outros estudos, os construtos relativos ao TAM mostraram-se adequados para a presente pesquisa. Dessa maneira, o estudo contribuiu no sentido de demonstrar ind?cios de que o Modelo de Aceita??o da Tecnologia pode ser aplicado ? predi??o da aceita??o de sistemas integrados de gest?o, mesmo em organiza??es p?blicas.
