In the United States, a number of federal laws establish requirements that electronic government (e-government) information and services be accessible to individuals with disabilities. These laws affect e-government Web sites at the federal, state, and local levels. To this point, research about the accessibility of e-government Web sites has tended to focus on compliance with Section 508 of the Rehabilitation Act. Though Section 508 has the most specific guidelines regarding Web site accessibility, it is hardly the only law establishing accessibility requirements for e-government Web sites, and Section 508 does not apply to many sites that may be required to be accessible by other laws. Until assessment of the accessibility of e-government Web sites accounts for all of the relevant laws, the understanding of levels of accessibility and compliance will be incomplete. This article examines the entire spectrum of federal laws that create legal requirements for accessible e-government Web sites, analyzing the accessibility requirements that the laws establish and the ways in which each of the laws applies to an e-government Web site. This article also suggests research areas that should be included in future assessments to address the entire range of laws related to the accessibility of e-government Web sites. The issues raised in this article have significant relevance to the design and development of e-government, to the assessment of e-government information and services, and to the inclusion in e-government of the 54 million individuals in the United States with disabilities.  相似文献

The main factor preventing non-visitors from visiting museums is ‘lack of interest’. But the causes of this ‘lack of interest’ are different in Taiwan than in western countries. Taiwanese non-visitors on low incomes are deterred by the strong association of museums with education. They want an experience that will be relaxing, enjoyable and pleasurable, and one which will not require any effort. They do not perceive museums as providing this. Non-visitors want museums to function more obviously as leisure venues that the whole family can actively enjoy. They say museums need to promote themselves as places for exploration and entertainment, as well as for education and learning. If museums wish to attract low-income non-visitors, they must consider how the needs of the non-visiting public can be met.  相似文献

This paper introduces the special issue by explaining the context of the conference at which the papers were originally presented, suggesting some ways of thinking about the intersection of philosophy and museums, and briefly introducing each paper in the collection. In the main body of the paper I look at a recent trend in museum interpretation and argue that it can be understood in terms of a definition of the museum as a space of representation and space of difference. I go on to suggest that this definition allows us to think of the museum as liberating us from certain ways of thinking. The paper as a whole suggests that philosophy can help us to think about museums, and that museums can contribute to philosophical thinking.  相似文献

Computer-based educational assessments often include items that involve drag-and-drop responses. There are different ways that drag-and-drop items can be laid out and different choices that test developers can make when designing these items. Currently, these decisions are based on experts’ professional judgments and design constraints, rather than empirical research, which might threaten the validity of interpretations of test outcomes. To this end, we investigated the effect of drag-and-drop item features on test-taker performance and response strategies with a cognition-centered approach. Four hundred and seventy-six adult participants solved content-equivalent drag-and-drop mathematics items under five design variants. Results showed that: (a) test takers’ performance and response strategies were affected by the experimental manipulations, and (b) test takers mostly used cognitively efficient response strategies regardless of the manipulated item features. Implications of the findings are provided to support test developers’ design decisions.  相似文献

This paper starts by outlining the technologies involved in RFIDs and reviews the issues raised by their general application. It then identifies their potential application areas within the library sector based on a generic process view of library activities. Finally it highlights the issues that are raised by their application in libraries and provides an assessment of which of these issues are likely to raise ethical concerns for library professionals. The purpose is to provide an overview of the technology within the context of the library process and to highlight issues which may raise ethical concerns for the profession. A second paper will focus specifically on these concerns within the context of the professional obligations of the librarian.  相似文献

As a first attempt to empirically investigate the scope of external information-seeking under uncertainty, this paper examines the direct and interactive effects of task uncertainty on the scope of external information-seeking. Search depth and breadth are the two components of the scope of external information-seeking in defining an individual's external information search strategy. The empirical results show that at the source portfolio level, task uncertainty exhibits positive effects on both the depth and breadth of external information-seeking. It is also found that there is a positive relationship between task uncertainty and depth-first propensity, which is defined as a seeker's propensity to acquire information through increasing search depth instead of through widening search breadth at the source portfolio level. Furthermore, the results show that the positive relationship between task uncertainty and depth-first propensity in external information-seeking is stronger when perceived source accessibility is low than when it is high. This study makes a contribution to the information-seeking literature by helping us understand how task uncertainty and source characteristics shape an individual's external information-seeking at the level of source portfolio and providing evidence of the task-source fit perspective in explaining information-seeking behaviour under uncertainty at the source portfolio level.  相似文献

Using push-pull-mooring framework and investment model as theoretical lenses, this study provides a compelling theoretical model that helps understand the important antecedents of career commitment of IT professionals. Especially, we examined the moderating role of IT career tenure. Data to test the hypotheses were drawn from a cross-sectional field study of MIS departments from top-1000 large-scale companies in Taiwan. The results generally supported the research model. Career satisfaction was the most important determinant of career commitment, followed by professional self-efficacy, threat of professional obsolescence and career investment. The moderating analysis revealed distinct patterns that IT professionals seemed to hold different attitudes about the careers at different stages. The career attitudes of senior IT professionals were largely driven by push factors. On the contrary, the expelling forces which driving people away from their current careers (push effects) and personal inhibitors and facilitators (mooring effects) seemed equally important to junior IT professionals on their attitudes toward committing to the IT career. Insight and implications on management strategy for IT/HR managers are discussed.  相似文献

The US response to the 2010 Haiti Earthquake was a large effort coordinated by three major agencies that worked in tandem with the Government of Haiti, the United Nations, and many countries from around the globe. Managing this response effort was a complex undertaking that relied extensively on knowledge management systems (KMS). For the first time, however, US government agencies employed social media technologies such as wikis and collaborative workspaces as the main knowledge sharing mechanisms. In this research we present a case study developed through action research of how these social media technologies were used, what influences they made on knowledge sharing, reuse, and decision-making, and how knowledge was effectively (and at times ineffectively) maintained in these systems. First-hand knowledge of the response is used, offering strategies for future deployment of social media and important research questions that remain regarding social media as knowledge management systems, particularly for disaster and emergency management.  相似文献
