Learning is critical to both economic prosperity and social cohesion. E-government learning, which refers to the government's use of web-based technologies to facilitate learning about subjects that are useful to citizens, is relatively new, relevant, and potentially cost-effective. This work proposes and verifies that the technology acceptance model (TAM) can explain and predict usage of e-government learning. The TAM examines how perceived ease of use and perceived usefulness and their antecedents influence intention and usage of a system. This study identifies antecedents that account for individual differences, thereby enhancing the explanatory power of the built model. A survey is used to collect data from users of an e-government learning website in Taiwan. Structural equation modeling is employed to examine the fit of the data to the model. From a theoretical point of view, this research extends the TAM to e-government learning and identifies the perceived e-government learning value and perceived enjoyment as antecedents of usage of e-government learning. This study also provides directions for future research and approaches to promote e-government learning. 相似文献

The paper discusses the interconnection of the adoption and diffusion of broadband (‘BB’), e-government (‘EG’) and e-commerce (‘EC’) services. It provides a structured literature review and proposes a conceptual framework for studying the interconnection of the development and adoption of BB, EG and EC. The interconnections of various concepts are shown along with several hypotheses that are thoroughly theoretically grounded. The role of different technology acceptance models is discussed, while the importance of including various aspects in policy preparation analyses is emphasized. 相似文献

The ability to vote online has the potential to increase voter turnout for elections due to increased convenience over traditional voting polls. This study examines factors that can affect a citizen's intent to vote online. Survey subjects came from two different age groups: young adults, 18–25 years of age; and senior citizens, ages 60 plus. Using the Unified Theory of Acceptance and Use of Technology (UTAUT), the study found that performance expectancy, effort expectancy, social influence, trust in the internet, and computer anxiety were significantly related to intent to use online voting. Trust in the government was insignificant. Performance expectancy, social influence, and computer anxiety were related to intent to vote online for both young adults and seniors. Effort expectancy was related to intent to vote for the seniors but not young adults, and trust in the internet was related to intent to vote for young adults but not seniors. 相似文献

研究生利用数据库资源的满意度及影响因素实证研究 总被引：1，自引：0，他引：1
本研究参考技术接受模型提出研究模型及假设,主要对五所高校的研究生进行抽样调查,通过实证分析探讨用户利用数据库资源的满意度及内部影响因素和外部影响因素。数据分析结果表明,研究生在利用数据库资源进行信息查寻时,利用数据库的满意度受到数据库服务质量、系统使用便利性和用户感知数据库有用的正向影响;而感知数据库有用会受到信息对需求的适应性、用户自我效能和感知数据库易用的正向影响,感知数据库易用会受到系统使用便利性和用户自我效能的正向影响;用户利用数据库查寻信息的意向则会同时受到用户感知数据库有用和用户利用数据库满意度的影响。本研究还发现,用户的性别差异会带来用户感知数据库易用、满意度和查寻意向的显著差异,用户使用数据库频率的差异会对感知数据库易用带来显著区别,年级差异会导致感知数据库有用的差异。 相似文献

This study assessed the use of “Personal Computer Technology” in public organizations of developing countries in South Asia, particularly in Pakistan [Qazi, R. (2006). Expanding the Technology Acceptance Model (TAM): A Consideration of Personal Computer Technology Use in Public Organizations of a Developing Country of South Asia, Pakistan (Doctoral dissertation, George Washington University, 2006). Dissertation Abstracts]. The study expanded the “Technology Acceptance Model” by adding additional external factors such as ‘Organizational Culture’ and ‘Individual Factors’ (e.g. ‘Level of Education’ and ‘Duration of Training’), and belief factors such as ‘Perceived Personal Utility.’ Financial compensation to employees was used as a control variable because preliminary data analysis showed that it explicitly differentiated results of the study between those employees who felt they were adequately rewarded (financially) and those who were not. For example, when respondents replied ‘Compensation’ was ‘Yes,’ i.e. that at least some level of direct compensation was provided for PCT utilization then a statistically significant, positive relationship between ‘Level of Education’ and ‘PCT Use’ was found. However, when respondents replied that ‘Compensation’ was ‘No,’ a statistically significant, negative relationship between ‘Level of Education’ and ‘PCT Use’ exists. Additional results of this study are presented in this article. 相似文献

The pace of implementing Electronic Government (E-Gov) is rapidly increasing. However, despite high levels of investment, a broad range of applications, and various methods of access relatively low levels of various methods of access, relatively low levels of usage (and even familiarity with e-gov) are still common. For example, in Canada, long recognized as a leader in implementing e-gov, less than 27% of Canadians used E-Gov during the past 12 months and 81% of c non-users report a low level of familiarity with either federal or provincial governmental services available through e-gov (Canada, 2004). Or, consider the showcase e-gov Gyandoot project in the Dhar district in central India, whose population is estimated at 1.7 million. Even after implementing e-gov in a showcase project for the rural poor, a study by the Center for Electronic Governance, Indian Institute of Management, Ahmedabad concluded that this model of “government to citizen” service delivery has serious sustenance problems (World Bank, 2004). The research reported in this paper takes a step back and focuses on the acceptability of e-gov by individuals. It is a people-centric approach to determine the overall acceptability of e-gov to people in a developing country, Saudi Arabia. Although this research may be generalizable to other situations, the primary intention of this project is to shed light on how to approach and manage implementation projects in developing nations. 相似文献

Assessing citizen adoption of e-Government initiatives in Gambia: A validation of the technology acceptance model in information systems success 总被引：1，自引：0，他引：1
The technology acceptance model (TAM) has been used extensively to explain and predict users' acceptance of corporate information technology (IT). With the advancement in IT and the expanding popularity of internet applications in Gambia, e-Government has been a priority factor in rendering government services and in making information more accessible to citizens. This study shows how the TAM and e-Government initiatives would positively impact the Gambian government, despite the cultural differences within the country. This study developed a successful model of the Gambian e-Government system to assist Gambians with more efficient and cost-effective government operations. The study results reveal that the core constructs of the TAM have strong influences on user-intention towards e-Government products. This implies that the Gambian government can potentially utilize this study's TAM findings in other contextual settings to design and promote further implementation of e-Government systems. 相似文献

This study examines the acceptance of cloud computing services in government agencies by focusing on the key characteristics that affect behavioral intent. The study expanded upon the technology acceptance model by incorporating contextual factors such as availability, access, security, and reliability. The research model was empirically verified by investigating the perception of users working in public institutions. Modeling results showed that user intentions and behaviors were largely influenced by the perceived features of cloud services. Also these features were found to be the significant antecedents of cloud computing usefulness and ease of use. The findings should guide governments' promotion of cloud public services to increase user awareness by enhancing usability and appeal and ensuring security. 相似文献

《Legal Reference Services Quarterly》2013,32(1-2):7-27
Critical Legal Studies presents numerous challenges to reference librarians. Among them are the difficulty of identifying and collecting materials written by Critical Legal Studies scholars, the problem of locating and acquiring materials about the Critical Legal Studies movement, and the use by Critical Legal Studies scholars of materials, vocabulary, and a style of scholarship not traditionally found in law schools. Librarians, particularly reference librarians, should be able to anticipate trends in the legal community. The Critical Legal Studies movement has existed for ten years, and yet the academic law library community has only recently responded to its existence by collecting matertals relevant to Critical Legal Studies scholars and by making those materials accessible through subject headings, bibliographies, and computerized legal research sources. 相似文献
