The tribal insignia of American Indians offer a distinctive view into the history of these people. Recently, as the result of federal legislation, some of these materials have been brought together, for tribes that are either federally or State recognized entities, as part of the database collection maintained by the United States Patent and Trademark Office (USPTO). This article focuses on the history and use of such images; the policy response by the USPTO to the charge by the Trademark Law Treaty Implementation Act (1998) to examine the USPTO's specific responsibility to protect such official insignia; and the Office's resulting digital product.  相似文献

As shared services organizations (SSO) become more popular as a service management and delivery option in government, properly defining and setting up the governance structure continues to be a key success factor. This paper explores the options and issues to consider when selecting and implementing shared services governance including topics such as oversight, accountability, culture, management of resources, and of day-to-day operations. Shared services organizations are increasingly common in private sector companies and the particular challenges involved in the governance of an SSO in a public service context are highlighted and discussed.  相似文献

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

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

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 Internet facilitates access to online product reviews and comments written by consumers. This paper offers new insights on the motives and antecedents of the reading behaviour of consumer reviews in online opinion platforms. This research was carried out from 2005 to 2008 using a case study approach. The case involved working with a prominent and successful online opinion platform (CIAO.com). The company was so successful it was purchased by Microsoft for $486 million in 2008 and is now incorporated into their main search engine which is still a market leader today. The research highlights four different types of motives that drive customers to read online reviews: decision-involvement, product-involvement, social-involvement and economic-involvement motives. The outcomes also demonstrated four different new types of motives: self-involvement motives, consumer-empowerment motives, new social-involvement motives and site-administration motives. Several related themes were also investigated, such as the preference for reading or writing online reviews and the reasons for choosing one over the other. The research tested the relevance of the online reading motives and their influence on consumer buying and communication behaviour. In summary, some theoretical and practical implications are highlighted and discussed.  相似文献

The concept of information is clearly foundational to the ‘information’ disciplines but lacking in a clear conceptual foundation. In this paper we propose that the concept is clearly overloaded and suggest that a new vocabulary is needed to enhance our powers of understanding and explanation. We argue that information is better situated at the intersection of signs, patterns and systems, which involves the enactment of forma (the substance of a sign), informa (the content of a sign) and performa (the use of signs in coordinated action). Within this perspective ‘information’ is considered an accomplishment not only of humans but also of animals. This leads us to use a well-documented case from the animal kingdom, that of communication amongst Gunnison prairie dogs, to both ground and expand upon significant elements from our conceptual framework. This we believe helps shed new light on what the juxtaposition of information with behaviour actually means.  相似文献

Consumers’ shopping intention is central to a Webstore's success. While past information system (IS) studies have examined this phenomenon extensively, they have focused on examining the single channel of e-tailing only. Knowledge of consumers’ cross-channel shopping behavior, which is common nowadays, was scarce. This study has empirically investigated a research model proposing how consumers’ brand loyalty in the retailing channel may impact on their shopping intentions at the same brand's Webstore. Specifically, in contrast to the system approach examined by past IS studies, this study has undertaken a brand perception approach and uncovered that by shaping consumers’ online perceptions of brand familiarity and Webstore reputation, consumers’ offline brand loyalty directly and indirectly enhances their trust in Webstore and lead to a higher shopping intention. Practical suggestions for click-and-mortar companies in building their channel strategies were proposed accordingly.  相似文献
