Uso da internet em ambiente acadêmico :estudo com docentes em institruição de educação tecnológica no Brasi

The last decade, characterized by the vertiginous growth of the computers worldwide net, brought radical changes in the use of the information and communication. Internet s use at business world has been largely studied; however, few are the researches about the academic use of this technology, mainly if we take into consideration institutions of technologic education. In this context, this research made an analysis of internet s use in a technologic education institution in Brazil, analyzing, in particular, the Centro Federal de Educação Tecnológica do Rio Grande do Norte CEFET/RN for that standard use of this Information Technology (IT) tools and, at the same time, studying the determinant factors of this use. To reach the considered objectives, a survey research was effected, be given data collected daily through the research s questionnaire application to 150 teachers who answered a set of closed and scaled questions. The quantitative data were qualitatively analyzed, arriving a some significant results related to the standard use and the factors that influenced in the use of these Internet technologies, like: the age scale, the exposition s to the computer level, the area of academic graduation, the area of knowledge where acts and the title, exert significant influence in the academic use of Internet between the professors

Analysis of the Slow Food movement impact on the farmers and rural areas’ sustainable development

The evaluation of the farmers’ communities’ approach to the Slow Food vision, their perception of the Slow Food role in supporting their activity and their appreciation and expectations from participating in the event of Mother Earth were studied. The Unified Theory of Acceptance and Use of Technology (UTAUT) model was adopted in an agro-food sector context. A survey was conducted, 120 questionnaires from farmers attending the Mother Earth in Turin in 2010 were collected. The descriptive statistical analysis showed that both Slow Food membership and participation to Mother Earth Meeting were much appreciated for the support provided to their business and the contribution to a more sustainable and fair development. A positive social, environmental and psychological impact on farmers also resulted. Results showed also an interesting perspective on the possible universality of the Slow Food and Mother Earth values. Farmers declared that Slow Food is supporting them by preserving the biodiversity and orienting them to the use of local resources and reducing the chemical inputs. Many farmers mentioned the language/culture and administration/bureaucratic issues as an obstacle to be a member in the movement and to participate to the event. Participation to Mother Earth gives an opportunity to exchange information with other farmers’ communities and to participate to seminars and debates, helpful for their business development. The absolute majority of positive answers associated to the farmers’ willingness to relate to Slow Food and participate to the next Mother Earth editions negatively influenced the UTAUT model results. A factor analysis showed that the variables associated to the UTAUT model constructs Performance Expectancy and Effort Expectancy were consistent, able to explain the construct variability, and their measurement reliable. Their inclusion in a simplest Technology Acceptance Model could be considered in future researches.

Modeling microblogging adoption in the enterprise

Despite a broad range of collaboration tools already available, enterprises continue to look for ways to improve internal and external communication. Microblogging is such a new communication channel with some considerable potential to improve intra-firm transparency and knowledge sharing. However, the adoption of such social software presents certain challenges to enterprises. Based on the results of four focus group sessions, we identified several new constructs to play an important role in the microblogging adoption decision. Examples include privacy concerns, communication benefits, perceptions regarding signal-to-noise ratio, as well codification effort. Integrating these findings with common views on technology acceptance, we formulate a model to predict the adoption of a microblogging system in the workspace. Our findings serve as an important guideline for managers seeking to realize the potential of microblogging in their company.

Development, implementation, and evaluation of a structured reporting web tool for abdominal aortic aneurysms

BACKGROUND The majority of radiological reports are lacking a standard structure. Even within a specialized area of radiology, each report has its individual structure with regards to details and order, often containing too much of non-relevant information the referring physician is not interested in. For gathering relevant clinical key parameters in an efficient way or to support long-term therapy monitoring, structured reporting might be advantageous. OBJECTIVE Despite of new technologies in medical information systems, medical reporting is still not dynamic. To improve the quality of communication in radiology reports, a new structured reporting system was developed for abdominal aortic aneurysms (AAA), intended to enhance professional communication by providing the pertinent clinical information in a predefined standard. METHODS Actual state analysis was performed within the departments of radiology and vascular surgery by developing a Technology Acceptance Model. The SWOT (strengths, weaknesses, opportunities, and threats) analysis focused on optimization of the radiology reporting of patients with AAA. Definition of clinical parameters was achieved by interviewing experienced clinicians in radiology and vascular surgery. For evaluation, a focus group (4 radiologists) looked at the reports of 16 patients. The usability and reliability of the method was validated in a real-world test environment in the field of radiology. RESULTS A Web-based application for radiological "structured reporting" (SR) was successfully standardized for AAA. Its organization comprises three main categories: characteristics of pathology and adjacent anatomy, measurements, and additional findings. Using different graphical widgets (eg, drop-down menus) in each category facilitate predefined data entries. Measurement parameters shown in a diagram can be defined for clinical monitoring and be adducted for quick adjudications. Figures for optional use to guide and standardize the reporting are embedded. Analysis of variance shows decreased average time required with SR to obtain a radiological report compared to free-text reporting (P=.0001). Questionnaire responses confirm a high acceptance rate by the user. CONCLUSIONS The new SR system may support efficient radiological reporting for initial diagnosis and follow-up for AAA. Perceived advantages of our SR platform are ease of use, which may lead to more accurate decision support. The new system is open to communicate not only with clinical partners but also with Radiology Information and Hospital Information Systems.

La telefonía móvil : el impacto social

El objetivo de este proyecto ha sido el de realizar un análisis del importante desarrollo que han sufrido las telecomunicaciones, haciendo un especial hincapié en la telefonía móvil y el impacto y repercusión que ha causado actualmente en nuestra sociedad. Para ello se hará un repaso evolutivo de las tecnologías de la información y las telecomunicaciones, y se establecerá una relación entre la gran difusión de éstas y su efecto sobre los usos, y cambios percibidos por los consumidores del nuevo siglo. Ciertamente la historia de la tecnología, nos enseña que la gente y las organizaciones acaban utilizándola para unos propósitos muy diferentes de aquellos que inicialmente fueron concebidas. Además cuanto más interactiva sea una tecnología, tanto más probable será que los usuarios se conviertan en productores o modificadores de la misma. Por tanto, la sociedad necesita resolver las incógnitas que pueda suscitar el rápido y continúo cambio de las comunicaciones. Este proyecto trata de ayudar a responder alguna de las cuestiones que actualmente se están planteando. ¿Son los teléfonos móviles una expresión de identidad, artilugios de moda, herramientas de la vida cotidiana, o todo lo anterior? ¿Existen nuevos modelos de comportamiento y conducta social? ¿La comunicación móvil está favoreciendo la aparición de una nueva cultura joven con un lenguaje propio basado en la comunicación textual y multimodal? ¿Tienen los teléfonos móviles efectos nocivos en la salud? La respuesta a estas preguntas afecta a nuestras vidas y también condiciona las políticas públicas y las estrategias de negocio, por eso requiere adquirir un conocimiento cimentado en la información, y la recopilación de datos de diversas fuentes, tanto de estadísticas provenientes de diferentes estudios e investigaciones, como de empresas consultoras, siempre basada en una perspectiva global. En conjunto, se espera dentro de los límites del conocimiento actual, contribuir a establecer las bases para el análisis y valoración de la relación existente entre comunicación, tecnología y sociedad en todo el mundo. Abstract The purpose of this project has been to analyse the significant development undergone by telecommunications, putting a special emphasis on mobile phones and the impact it has caused in society. We will go over the evolution of IT technologies and telecommunications as well as establish a relationship between its spread and effect of its uses and changes understood by the new century consumers. Technology history shows us that people and organizations use it for very different purposes from those originally thought. Furthermore, the more interactive technologies are, the more users will modify or produce it. Therefore, society needs to solve the mysteries of the quick and continuous change of communications. This project tries to help and answer some of the questions considered these days. Are mobile phones an expression of identity, fashionable devices, tools for everyday life or all at once? Are there any new models of performance and social behaviour? Is mobile communication favouring the existence of a new young culture with a typical language based on textual and multimodal communication? Are mobile phones bad for our health? The answer to these questions affects us all and conditions public politics and business strategies so it is required to get firm knowledge based on information. It is also important to compile data from various sources, from statistics of research and studies, based on a global perspective. As a whole, we hope to contribute to establish the bases for the future analysis and assessment of a fundamental trend that is redefining the relationship between communication, technology and society worldwide by transforming the wireless networks that make our lives.

Factors affecting student attitudes toward flexible online learning in management education

In response to recent technological advances and the trend toward flexible learning in education, the authors examined the factors affecting student satisfaction with flexible online learning. The authors identified 2 key student attributes of student satisfaction: (a) positive perceptions of technology in terms of ease of access and use of online flexible learning material and (b) autonomous and innovative learning styles. The authors derived measures of perceptions of technology from research on the Technology Acceptance Model and used locus of control and innovative attitude as indicators of an autonomous and innovative learning mode. First-year students undertaking an introductory management course completed surveys at the beginning (n = 248) and at the end (n = 256) of course work. The authors analyzed the data by using structural equation modeling. Results suggest that student satisfaction is influenced by positive perceptions toward technology and an autonomous learning mode.

National culture, infrastructure, and costs: Factors that lead to the use of wireless technologies

This research-in-progress paper utilizes the Technology Acceptance Model (TAM) to assess the effects of National Culture, Infrastructure, and Access Costs on the adoption of Wireless Technologies in Australia. The cultural dimensions emanating from the GLOBE project were chosen because of their broad coverage and contemporary nature. Australia is unique in that it has one of the lowest population densities in the world. The provision of wireless technologies is challenging in such an environment, and I believe the model developed in this research will have applicability in other similarly populated countries.

Instant messaging: A cross-country comparison of factors affecting adoption

This research-in-progress paper utilizes the Technology Acceptance Model (TAM) to determine whether differences exist in the adoption of Instant Messaging (IM) Technologies in Australia, China, Mexico and the USA. Despite significant differences in the technology needed to implement IM (e.g., software supporting Chinese language characters), few barriers exist to the adoption of IM given the environment is in place. We postulate that language interface technology, infrastructure, and culture affect the adoption of IM technology.

AVALIAÇÃO DA ACEITAÇÃO DO PORTAL INOVAÇÃO: UM ESTUDO DE CASO

Esta pesquisa apresenta estudo de caso cujo objetivo foi analisar a aceitação do Portal Inovação, identificando os fatores preditivos da intenção comportamental de uso e do comportamento de uso direcionadores da adoção da tecnologia por seus usuários via extensão do Modelo Unificado de Aceitação de Tecnologia, denominado pela sigla UTAUT (Unified Theory of Acceptance and Use of Technololgy) de Venkatesh et al. (2003). O objeto da pesquisa o Portal Inovação foi desenvolvido pelo Ministério da Ciência, Tecnologia e Inovação (MCTI) em parceria com o Centro de Gestão e Estudos Estratégicos (CGEE), Associação Brasileira de Desenvolvimento Industrial (ABDI) e Instituto Stela, visando atender às demandas do Sistema Nacional de Ciência, Tecnologia e Inovação (SNCTI) do País. Para atingir os objetivos propostos, recorreu-se às abordagens qualitativa, que foi subsidiada pelo método estudo de caso (YIN, 2005) e quantitativa, apoiada pela metodologia UTAUT, aplicada a usuários do portal e que contemplou o resultado de 264 respondentes validados. Quanto ao material de análise, utilizou-se da pesquisa bibliográfica sobre governo eletrônico (e-Gov), Internet, Sistema Nacional de Inovação, modelos de aceitação de tecnologia, dados oficiais públicos e legislações atinentes ao setor de inovação tecnológica. A técnica de análise empregada quantitativamente consistiu no uso de modelagem por equações estruturais, com base no algoritmo PLS (Partial Least Square) com bootstrap de 1.000 reamostragens. Os principais resultados obtidos demonstraram alta magnitude e significância preditiva sobre a Intenção Comportamental de Uso do Portal pelos fatores: Expectativa de Desempenho e Influência Social. Além de evidenciarem que as condições facilitadoras impactam significativamente sobre o Comportamento de Uso dos usuários. A conclusão principal do presente estudo é a de que ao considerarmos a aceitação de um portal governamental em que a adoção é voluntária, o fator social é altamente influente na intenção de uso da tecnologia, bem como os aspectos relacionados à produtividade consequente do usuário e o senso de utilidade; além da facilidade de interação e domínio da ferramenta. Tais constatações ensejam em novas perspectivas de pesquisa e estudos no âmbito das ações de e-Gov, bem como no direcionamento adequado do planejamento, monitoramento e avaliação de projetos governamentais.

BIBLIOTECA VIRTUAL: UMA ANÁLISE DOS FATORES ANTECEDENTES DA INTENÇÃO DE USO DOS ESTUDANTES DO ENSINO SUPERIOR

Diversos estudos sobre a aceitação e o uso de tecnologias de informação têm sido realizados por diferentes modelos conceituais que buscam demonstrar a existência de fatores que influenciam a intenção e comportamento dos usuários sobre um determinado sistema de informação. Alguns aspectos que potencializam as intenções de uso podem ser fundamentais para que o indivíduo adote, ou não, uma determinada tecnologia. Este estudo analisou os fatores antecedentes que podem influenciar a intenção de uso da Biblioteca Virtual de uma Instituição de Ensino Superior (IES). Dentre os modelos conceituais que estudam a adoção de tecnologias de informação, optou-se nesta pesquisa pelo Modelo de Aceitação de Tecnologia (TAM) proposto por Davis (1986). Neste modelo ainda foram adicionadas as variáveis externas Estímulo Docente e Hábito a fim de ampliar o poder de explicação da intenção de uso dos usuários em questão. Através de uma abordagem de investigação quantitativa, os dados foram coletados por meio de um instrumento de pesquisa com obtenção de resposta de 406 questionários. Os resultados obtidos por esta pesquisa confirmam a influência de diversos fatores posicionados em diferentes dimensões e proporcionam conclusões relevantes à adoção da biblioteca virtual. Conclui-se que o Estímulo Docente influencia positivamente a Facilidade de Uso, Utilidade Percebida e o Habito dos alunos de graduação sobre a intenção de uso da Biblioteca Virtual. Com isso, constatou-se que a influência do professor torna-se um fator determinante na intenção de uso da biblioteca virtual, o que ressalta a importância da orientação e recomendação dos professores no uso desta ferramenta tecnológica. O estudo concluiu que a utilidade percebida revelou-se o fator que mais influencia a intenção de uso desta tecnologia, pois há a percepção de que, caso o aluno venha utilizar a biblioteca virtual, pode-se melhorar seu desempenho nos estudos, entre outros aspectos. O Hábito também pode influenciar à adoção da biblioteca virtual de forma paralela às percepções sobre os benefícios que podem ser obtidos com o uso desta tecnologia.

Antecedents and consequences of service quality in consumer evaluation of self-service internet technologies

Advances in technology coupled with increasing labour costs have caused service firms to explore self-service delivery options. Although some studies have focused on self-service and use of technology in service delivery, few have explored the role of service quality in consumer evaluation of technology-based self-service options. By integrating and extending the self-service quality framework the service evaluation model and the Technology Acceptance Model the authors address this emerging issue by empirically testing a comprehensive model that captures the antecedents and consequences of perceived service quality to predict continued customer interaction in the technology-based self-service context of Internet banking. Important service evaluation constructs like perceived risk, perceived value and perceived satisfaction are modelled in this framework. The results show that perceived control has the strongest influence on service quality evaluations. Perceived speed of delivery, reliability and enjoyment also have a significant impact on service quality perceptions. The study also found that even though perceived service quality, perceived risk and satisfaction are important predictors of continued interaction, perceived customer value plays a pivotal role in influencing continued interaction.

Looking under the bonnet:factors affecting student adoption of e-learning systems in Jordan

The primary questions addressed in this paper are the following: what are the factors that affect students’ adoption of an e-learning system and what are the relationships among these factors? This paper investigates and identifies some of the major factors affecting students’ adoption of an e-learning system in a university in Jordan. E-learning adoption is approached from the information systems acceptance point of view. This suggests that a prior condition for learning effectively using e-learning systems is that students must actually use them. Thus, a greater knowledge of the factors that affect IT adoption and their interrelationships is a pre-cursor to a better understanding of student acceptance of e-learning systems. In turn, this will help and guide those who develop, implement, and deliver e-learning systems. In this study, an extended version of the Technology Acceptance Model (TAM) was developed to investigate the underlying factors that influence students’ decisions to use an e-learning system. The TAM was populated using data gathered from a survey of 486 undergraduate students using the Moodle based e-learning system at the Arab Open University. The model was estimated using Structural Equation Modelling (SEM). A path model was developed to analyze the relationships between the factors to explain students’ adoption of the e-learning system. Whilst findings support existing literature about prior experience affecting perceptions, they also point to surprising group effects, which may merit future exploration.

Participatory design with older adults for healthcare apps

The global population of people aged 60 years and older is growing rapidly [1]. Ongoing advances in mobile technologies have the potential to improve independence and quality of life of older adults by supporting the delivery of personalised and ubiquitous healthcare solutions. Suggested healthcare reforms reflect the need for a future model of healthcare delivery wherein older adults take more responsibility for their own healthcare in their own homes in an attempt to moderate healthcare costs without impairing healthcare quality. For such a paradigm shift to be realised, the supporting technology must address the needs of older patients efficiently and effectively to ensure technology acceptance and use. We argue this is not possible without employing participatory approaches for the informed and effective design and development of such technologies and outline recommendations for engaging in participatory design with older adults with impairments based on practical experience.

Globalization of the Internet: Convergence or a multicultural community?

The purpose of this dissertation was to investigate cross-cultural differences in the use of the Internet. Hofstede's model of national culture was employed as the theoretical foundation for the analysis of cross-cultural differences. Davis's technology acceptance model was employed as the theoretical foundation for the analysis of Internet use. ^ Secondary data from an on-line survey of Internet users in 22 countries conducted in April 1997 by the Georgia Tech Research Corporation measured the dependent variables of Internet use and the independent variables of attitudes toward technology. Hofstede's stream of research measured the independent variables of the five dimensions of national culture. ^ Contrary to expectations, regression analyses at the country level of analysis did not detect cultural differences. As expected, regression analyses at the individual level of analysis did detect cultural differences. The results indicated that perceived usefulness was related to the frequency of Internet shopping in the Germanic and Anglo clusters, where masculinity was high. Perceived ease of use was related to the frequency of Internet shopping in the Latin cluster, where uncertainty avoidance was high. Neither perceived usefulness nor perceived ease of use was related to the frequency of Internet shopping in the Nordic cluster, where masculinity and uncertainty avoidance were low. ^ As expected, analysis of variance at the cluster level of analysis indicated that censorship was a greater concern in Germany and Anglo countries, where masculinity was high. Government regulation of the Internet was less preferred in Germany, where power distance was low. Contrary to expectations, concern for transaction security. was lower in the Latin cluster, where uncertainty avoidance was high. Concern for privacy issues was lower in the U.S., where individualism was high. ^ In conclusion, results suggested that Internet users represented a multicultural community, not a standardized virtual community. Based on the findings, specific guidance was provided on how international managers and marketers could develop culturally sensitive strategies for training and promoting Internet services. ^
