Fatores críticos de sucesso como antecedentes da aceitação de um sistema de informação em uma universidade federal

In recent decades the public sector comes under pressure in order to improve its performance. 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 ²) 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.

Fatores que influenciam a intenção de compra online: aplicação de um modelo adaptado de aceitação da tecnologia para o comércio eletrônico

This research aims to understand the factors that influence intention to online purchase of consumers, and to identify between these factors those that influence the users and the nonusers of electronic commerce. Thus, it is an applied, exploratory and descriptive research, developed in a quantitative model. Data collection was done through a questionnaire administered to a sample of 194 graduate students from the Centre for Applied Social Sciences of UFRN and data analysis was performed using descriptive statistics, confirmatory factorial analysis and simple and multiple linear regression analysis. The results of descriptive statistics revealed that respondents in general and users of electronic commerce have positive perceptions of ease of use, usefulness and social influence about buying online, and intend to make purchases on Internet over the next six months. As for the non-users of electronic commerce, they do not trust the Internet to transact business, have negative perceptions of risk and social influence over purchasing online, and does not intend to make purchases on Internet over the next six months. Through confirmatory factorial analysis six factors were set up: behavioral intention, perceived ease of use, perceived usefulness, perceived risk, trust and social influence. Through multiple regression analysis, was observed that all these factors influence online purchase intentions of respondents in general, that only the social influence does not influence the intention to continue buying on the Internet from users of electronic commerce, and that only trust and social influence affect the intention to purchase online from non-users of electronic commerce. Through simple regression analysis, was found that trust influences perceptions of ease of use, usefulness and risk of respondents in general and users of electronic commerce, and that trust does not influence the perceptions of risk of non-users of electronic commerce. Finally, it was also found that the perceived ease of use influences perceived usefulness of the three groups. Given this scenario, it was concluded that it is extremely important that organizations that work with online sales know the factors that influence consumers purchasing intentions in order to gain space in their market

MAPEAMENTO DE CONHECIMENTO EM INSTITUIÇÕES DE ENSINO SUPERIOR: UM ESTUDO DE CASO NA REGIÃO CENTRO-OESTE

As empresas utilizam vários tipos de recurso para suas operações, logística, recursos financeiros, recursos humanos bem como recursos para gerar seu portfólio de produtos e serviços. No último século os gestores de empresas desenvolveram práticas e ferramentas para maximizar os resultados decorrentes da aplicação destes recursos. Esta dissertação aborda o problema da falta conhecimento a respeito do processo de mapeamento e gestão do conhecimento dentro de uma IES e objetiva propor um protótipo de mapeamento e gestão do conhecimento em uma instituição de ensino superior, para identificar as competências presentes dentro de uma IES. Esse trabalho está inserido no contexto organizacional de uma IES que, devido às constantes evoluções mercadológicas, necessita saber qual é o seu capital humano, o conhecimento que possui e quais são esses, pautado em uma ferramenta computacional. De acordo com o exposto, a dissertação segue o perfil acadêmico criando um protótipo que pode ser aplicado ao viés mercadológico. A importância da pesquisa acadêmica pode ser pautada no conhecimento que foi gerado a partir do estudo e da análise para a elaboração da dissertação; o conhecimento poderá ser replicado em outras IES, pois, a partir do protótipo construído e aplicado em uma Instituição de Ensino Superior, sua evolução ao ser utilizado/aprimorado em outra IES seria natural. A proposta e implementação de um protótipo com requisitos básicos apresentados nesta dissertação, possuem vários pontos em comum com a gestão do conhecimento, em que a ideia de desenvolver um protótipo de sistema de mapeamento de conhecimento nasce a partir de um repositório de dados (Plataforma Lattes), no qual os pesquisadores, cientistas, e alunos de programas de pós-graduação possuem seus currículos armazenados. As pesquisas e o aprimoramento técnico adquiridos com a construção dessa dissertação, com o objetivo de apresentar um protótipo de mapeamento do conhecimento utilizando ferramentas de código aberto (não pagas) para o seu desenvolvimento, tem a finalidade de identificar as competências presentes dentro de uma IES.

Investimentos ambientais e o desempenho econômico das empresas: um estudo utilizando dados em painel

A responsabilidade social empresarial é vista de maneira genérica como o comprometimento da empresa para com a sociedade. O papel das organizações na sociedade tem provocado discussões por meio de duas correntes teóricas distintas: a Teoria dos Shareholders (acionistas) e a Teoria dos Stakeholders (partes interessadas). Diante desse cenário, este estudo tem como objetivo analisar a relação entre os investimentos ambientais e o desempenho econômico das empresas. Para tanto, desenvolveu-se uma pesquisa aplicada, com abordagem quantitativa, documental e descritiva, contando com uma amostra de 353 empresas, compreendendo as informações contidas nos balanços sociais modelo IBASE publicados no período de 1996 a 2007. No tratamento dos dados, realizou-se a estimação de modelo econométrico com dados em painel com análise de regressão múltipla por Mínimos Quadrados Ordinários. Os resultados indicam que os Investimentos Ambientais Internos (IAI) e os Investimentos Ambientais Externos (IAE) impactam, de modo significante, tanto a Receita Líquida (RL) das empresas quanto o Resultado Operacional (RO). Constata-se, ao generalizar, que os setores não apresentam características de homogeneidade interna e não há diferenciação entre setores capaz de explicar o desempenho econômico de forma diferenciada, sendo o único setor significativo o de petróleo e gás.

Telefone celular como recurso didático no ensino de física

Currently, there are several factors that suggest the need for the school to review their teaching practices: 1) the speed with which information and communication technologies - ICT are spread throughout society and in particular the increasing use of mobile phone by groups in school age;2) the scope and power of integrating ICT convergence of these technological resources, that can be used as teaching resources; 3) the fact that nowadays students grow up in a technological world and make their thought patterns operating in accordance with this reality, etc... In contrast, there are educators unrelated to the appropriation of ICT, presenting, in many cases, resistance to them. There is a incongruity between how individuals use mobile phones, for example, inside and outside the school. There are also educators, schools, public educational departments claiming to be against mobile phones usage; bills and laws regulating their use in educational space, etc... For these controversial aspects we have investigated whether cell phone use as a teaching resource practices mediator in Physics teaching. For this purpose, we developed an applied research with qualitative and exploratory approach about the objectives, adopting participant and the technical procedures. A documental and bibliographical research was taken. First of all, data were collected by e-mail, through a multiple choice questionnaire applied to private school teachers in southern Brazil, to identify the researched reality and develop teaching practices likely to be applied in the studied corpus. Then, such practices were applied in workshops located in Curitiba and Ponta Grossa cities, in Paraná state. During the application, data was collected by the researcher's field notes. Then, we recorded chats about the workshops from an instant message software (msn messenger), and we took photographic records. Data analysis was performed by triangulation. The results showed the need to enhance continuing education courses for teachers and the production of national academic literature, such as articles, dissertations, theses and books that explore the theme of the cell phone and its functionality in educational spaces as an educational resource mediator in the practices of teaching Physics. They are available in the dissertation defended in 2012, and now are also systematized in this book, organized as a final product of research conducted by the Graduate Program in Science Education and Technology UTFPR, Campus Ponta Grossa-PR.

Las posibilidades de internet en la reconfiguración de la red social primaria del adulto mayor, fracturada por efecto de la migración* El caso de los adultos mayores con parientes migrantes en 6 municipios del departamento del Quindío

El presente artículo muestra cómo Internet se convierte en una herramienta de comunicación importante para reconfigurar la red social primaria del adulto mayor, fracturada por efecto de la migración. En la investigación que le da origien, se pudo constatar que hoy esta red se encuentra dividida en red primaria natural, conformada por los parientes y amigos con los que comparte el día a día, y red primaria virtual, integrada por los parientes migrantes. El escrito centra su interés en presentar las características de la red primaria virtual en la que el adulto mayor se vio impelido a participar para satisfacer sus necesidades comunicacionales. Esta red cumple la función de mantener, pero no de extender, su red social primaria. Los resultados dan cuenta de 4 aspectos: las competencias digitales desarrolladas por el adulto mayor, la estructura, las funciones y los atributos de vínculo de la red primaria virtual. Para ello se acudió a autores como Cabrera, Castell; Madarriaga, Abello & Sierra; Narváez A.; Soto, Navarro & Sánchez; Tovar & Villarraga. La investigación fue de tipo etnográfico, con enfoque cualitativo. Se aplicaron entrevistas semi-estructuradas. Para el tratamiento de la información se utilizó la teoría Fundamentad, de Strauss & Corbin (2002).

Mediação da informação em arquivos: a necessidade da consolidação da prática do serviço de referência

A disseminação da informação tornou-se uma das maiores preocupações das Ciências da Informação na contemporaneidade, sendo viabilizada por meio do processo de mediação. Esse processo é fruto das novas necessidades demandadas pelas atuais organizações, as quais estão inseridas no paradigma do acesso informacional, tendo o usuário da informação especial atenção. Sendo assim, este artigo analisa as práticas de mediação da informação realizadas em um arquivo privado, investigando se tais práticas garantem a concretização de um serviço de referência centrado nas reais necessidades dos usuários. Com esta proposta, o estudo contextualiza o processo de mediação da informação, apresenta o serviço de referência em unidades de informação e expõe as práticas de mediação ocorridas em um arquivo privado. Metodologicamente, foram utilizadas revisão de literatura e pesquisa aplicada por meio de entrevista a um arquivista. Os resultados confirmam que o arquivo analisado, embora realize a mediação, esse processo não é realizado de forma intensa, não concretizando, conforme descrito pela literatura, a prática do serviço de referência na unidade arquivística.

Gestão da cadeia de suprimento e vantagem competitiva: uma análise em setores industriais a partir da visão relacional

This work has as its main purpose to investigate the contribution of supply chain management in order to obtain competitive advantage by companies from the textile industry and from Ceará footwear industry, focusing its analysis mainly in the interorganizational relations (dyadic). For this, the theoretical referential contemplates different explanatory streams of the competitive advantage, detaching the relational perception of the resources theory, as well as, the main presuppositions of the supply chain management which culminates with the development of an analysis sample that runs the empirical study; the one which considers an expanded purpose of the supply chain which includes the government and the abetment institutions as institutional environment representatives. Besides supply chain management consideration as a competitive advantage source, the work also tried to identify other possible competitive advantage sources for the companies of the investigated sectors. It represents a study of multiple interpretive cases, having four cases as a total; meaning two cases in each one of the sectors, which used as a primary data collecting instrument a semi-structured interview schedule. Different methods were used for the data analysis, the content analysis and the constant comparison methods, the analytical procedure originated from the grounded theory research strategy, which were applied the Atlas/ti software recourse. Considering the theoretical referential and the used analysis sample, four basic categories of the work were defined, including its respective proprieties and dimensions: (1) characteristics concerning to the relationship with the supplier; (2) the company relations with the government; (3) the company relations with the abetment institutions and; (4) obtaining sources of competitive advantage. In general, the applied research in the footwear sector revealed that in the relationships of the researched companies related to its suppliers, there is a predominance of the partnership system and the main presuppositions of the supply chain management are applied which contributes for the acquisition of the relational competitive advantage; while in the textile sector, only some of these presuppositions are applied, with little contribution for the relational competitive advantage. The main resource which was accessed by the companies in both sectors through its relationships with the government and the abetment institutions are the tax incentives which, for the footwear companies, contribute for the acquisition of the temporary competitive advantage in relation to the contestants who do not own productive installations in the Northeast region, it also conducts to a competitive parity situation in relation to the contestants who own productive installations in the Northeast region and to the external market contestants; while for the companies of the textile sector, the tax incentives run the companies to a competitive parity situation in relation to its contestants. Furthermore, the investigated companies from the two sectors possess acquisition sources of the competitive advantage which collimate with different explanatory streams (industrial analysis, resources theory, Austrian school and the dynamic capabilities theory), although there is a predominance of the product innovation as a competitive advantage source in both sectors, due to the bond of these with the fashion tendencies

Imagens do terceiro setor: um estudo com pais e responsáveis financeiros das organizações educacionais

The present report is the result of an applied research in the educational entities of the third sector, aiming to demonstrate whether the financial influences the perception of users on the image of those entities. For both used the prospect of integrative marketing relationship adapting to and developing a set of indicators which bore the measurement of images from the model of Machado et al (2005) and Kotler and Fox (1994). The sample included a total of 187 parents and financial responsibility in 03 (three) institutions of education in Natal / RN. These data were processed by multivariate statistical analysis, factor analysis, linear regression, analysis of cluster and discriminant analysis. The factor analysis also identified 6 images perceived by users of services. Next were the relationships of cause and effect between the financial and images formed. In discriminant analysis, was identified two distinct groups of parents and guardians with financial perceptions similar and well defined. The result of the work shows that the differential level of financial participation of parents and guardians not influence the formation of the images formed from educational institutions of the third sector

Heritage assets : procedimentos para o reconhecimento e a mensuração adotados pelos museus

Este artigo teve como objetivo principal efetuar a análise das demonstrações contábeis de museus localizados nos cinco continentes, visando identificar o tratamento contábil relacionado ao reconhecimento e à mensuração dos heritage assets (HAs). Para tanto, aborda as definições de heritage assets, bem como o tratamento contábil discutido na literatura e definido pelas normas aplicáveis aos museus dos países foco deste estudo. Trata-se de uma pesquisa aplicada, qualitativa, descritiva e documental, conduzida a partir da análise do conteúdo dos relatórios anuais, demonstrações contábeis e respectivas notas explicativas de nove museus localizados na Nova Zelândia, Austrália, Reino Unido, África do Sul, Brasil, Canadá, Peru, Argentina e Estados Unidos. A partir da análise dos documentos, verificaram-se práticas heterogêneas, sendo o HA evidenciado em apenas uma parcela dos Balanços Patrimoniais, com destaque para as entidades situadas na Nova Zelândia e na Austrália, as quais apresentam o detalhamento mais completo e robusto. Quanto aos critérios de mensuração adotados pelos museus, o custo histórico é adotado principalmente para o reconhecimento inicial, enquanto outros critérios (valor justo, valor de mercado, custo de reposição e julgamento de profissionais especializados) são utilizados na mensuração subsequente. ______________________________________________________________________________ ABSTRACT

Ensaio em torno de uma cultura estratégica portuguesa

O que é a cultura estratégica? Será que a viragem cultural nos estudos de segurança a que se pode assistir nas últimas duas décadas faz sentido e pode ser aplicado de forma pertinente ao caso de Portugal? Iremos argumentar que sim. E para o demonstrar começaremos por procurar definir o que é e para que serve esta noção de cultura estratégica. Para depois defender que se a cultura estratégica pode mudar, porém, muda a custo, e é portanto natural para uma primeira avaliação da sua pertinência e desenho de um programa de pesquisa aplicada ao caso de Portugal comece por procurar detetar nos comportamentos, nas opções estratégicas de longo prazo traços definidores de uma cultura estratégica nacional informal, genérica, amplamente partilhada e de grande duração; a qual condicionou as perceções e preferências na prossecução dos interesses do Estado português, em particular quanto ao uso da força.

Contribuição ao desenvolvimento de ontologias para processos petroquímicos : estudo de caso em uma planta DEA

In the last decades, the oil, gas and petrochemical industries have registered a series of huge accidents. Influenced by this context, companies have felt the necessity of engaging themselves in processes to protect the external environment, which can be understood as an ecological concern. In the particular case of the nuclear industry, sustainable education and training, which depend too much on the quality and applicability of the knowledge base, have been considered key points on the safely application of this energy source. As a consequence, this research was motivated by the use of the ontology concept as a tool to improve the knowledge management in a refinery, through the representation of a fuel gas sweetening plant, mixing many pieces of information associated with its normal operation mode. In terms of methodology, this research can be classified as an applied and descriptive research, where many pieces of information were analysed, classified and interpreted to create the ontology of a real plant. The DEA plant modeling was performed according to its process flow diagram, piping and instrumentation diagrams, descriptive documents of its normal operation mode, and the list of all the alarms associated to the instruments, which were complemented by a non-structured interview with a specialist in that plant operation. The ontology was verified by comparing its descriptive diagrams with the original plant documents and discussing with other members of the researchers group. All the concepts applied in this research can be expanded to represent other plants in the same refinery or even in other kind of industry. An ontology can be considered a knowledge base that, because of its formal representation nature, can be applied as one of the elements to develop tools to navigate through the plant, simulate its behavior, diagnose faults, among other possibilities
