This paper examines the relative importance and significance of the four technology enablers introduced by Davis (1989) in the technology acceptance model (TAM) (perceived ease of use, perceived usefulness, attitude towards using and behavioural intention) for use on four different levels of citizen engagement in e-government (null, publish, interact and transact). An extended technology acceptance model (TAM) is developed to test citizen engagement towards online e-government services from a sample of 307 citizens who used the benefits advisor tool within a Spanish City Hall. Although the proposed model follows TAM and explains the intention towards the actual use of e-government by postulating four direct determinants, “A, PU, PEOU and BI” have been considered as parallel processes, meaning that each can have separate influence in different levels of citizen engagement. To achieve this goal, a multinomial logistic regression is developed and tested to confirm the explanatory power of the four technology enablers on the four different levels of e-government. Our findings further suggest that in order to implement e-government, some of the enablers matter more than others to move from one level of citizen engagement to another. The main contribution of the paper is to question the use of existing models which seek to represent the relationship between technology enablers and the adoption of e-government services without considering their impacts on citizens’ engagement. The implications of the findings are discussed and useful insights are provided in relation to policy recommendations geared to create appropriate conditions to build citizens’ engagement intent of use of e-government services. 相似文献

In Portugal, the number of students in higher education increased from 80,000 in 1975 to 381,000 in 2000 (a change from 11% to 53% in the age group 18–22), meaning a major change in the diversity of student population with consequences well known and studied in other countries. The teaching of chemistry at the University of Aveiro, for the first‐year students of science and engineering, has been subjected to continuous attention to implement quality and student‐centred approaches. The work devoted to excellence and deep learning by several authors has been carefully followed and considered. This communication reports research work on chemistry teaching, associated with those developments for first‐year students. The work included the design of strategies and the adoption of teaching and learning activities exploring ways to stimulate active learning by improving the quality of classroom interactions. In addition to regular lectures, large classes' teaching based on student‐generated questions was explored. In order to improve students' motivation and stimulate their curiosity, conference‐lectures were adopted to deal with selected topics of wide scientific, technological and social interest. Quantitative analysis and discussion of selected case studies, together with the organization of laboratory classes based on selected enquiry‐based experiments, planned and executed by students, stimulated deep learning processes. A sample of 32 students was followed in the academic year of 2000/01 and the results obtained are here discussed in comparison with those of a sample of 100 students followed in 2001/02. Particular attention was paid to the quality of classroom interactions, the use of questions by students and their views about the course design. 相似文献

The media industry is undergoing comprehensive change due to the shifting audience and consumption patterns fostered by the diffusion of the Internet. This article describes how these changes shape established practices of video production and redefine the cultural categories of video and broadcasting. Drawing on an empirical case study of the practices within the British Broadcasting Corporation (BBC), the we show the production of video content to be increasingly unbundled and broken down into several smaller processes, which make it possible to manage and recompose in a variety of ways that transcend established institutional divisions and cultural perceptions. At the same time and as a means of accommodating multiplatform content delivery, video distribution is acquiring flexible and mutating formats that further destabilize the perception of video as a self-sufficient cultural form. In this context, video metadata rises to be an important coordinative medium that provides the cognitive resources for identifying and managing video content within and across particular settings and the link through which the operations of media organizations become entangled with the technical landscape of the Internet. 相似文献

《韦护》是一部“革命加恋爱”式的作品,虽然在学史上的成就不高,但他们为学带来了属于他们自己的东西:一批新的学形象,一股自由奔放的气概。仅仅将其作为一种学模式加以彰显是不全面的。我们应当注意到在这样一种叙事方式下。一种不成熟但却不失真实的知识分子心态得到了相应的呈现。 相似文献
