Software must evolve in order to adapt to new demands and scenarios. In the case of packaged software that can be customized, this evolution implies the maintenance of both out-of-the-box and customized functionality alike. New user interface technologies provide a way to interact with applications that software vendors are forced to incorporate in order to meet new user and market requirements. Packaged software vendors are facing software evolution processes in order to attract more customers and conserve the existing ones. This case analysis describes the evolution of packaged software, Meta4 PeopleNet, towards the addiction of Rich Internet Applications features to a Human and Intellectual Capital Management tool. The findings and lessons learned presented in this case study provide useful insights for packaged software vendors facing software product evolution.  相似文献

The Internet plays a critical role in informing individuals about society, politics, business, and the environment. So much so that it has been said that the digital divide makes the segment of society on the “right side” of the divide (the digitally endowed group) better off and that on the “wrong side” (the digitally challenged group) worse off. This is not always true, however, in a social choice situation where members of a society collectively choose one alternative from a set of alternatives. To identify conditions when this does not hold, a model of the digital divide is setup in which the digitally endowed group receives better information than the digitally challenged group. Preferences of all individuals over outcomes are distributed over a scale. This distribution is correlated with the digital divide: the outcome preferred by the digitally endowed group differs from that preferred by the other group. The alternative chosen by majority becomes the choice of the overall society. The ensuing analysis shows that individuals located centrally on the preference scale are sensitive to information about the state. The choice of centrally located digitally challenged individuals, made on a lack of information, makes the digitally challenged group worse off as has been predicted before. In some cases, the digitally endowed group is worse off as well. In the case of highly polar alternatives, social welfare decreases due to the welfare loss of the digitally endowed group. Results suggest that policymakers must manage the digital divide in a customized manner depending on the preferences context. They should not only focus on improving the welfare of the digitally challenged, but also focus on the welfare of the digitally endowed group so that this welfare does not decrease.  相似文献

Usability methods have received relatively little methodological attention within the field of E-Government. This paper aims to address this gap by reporting on a usability test of the municipal website of Deventer (the Netherlands), carried out by means of three variants of the think-aloud method (concurrent/retrospective think-aloud protocols and constructive interaction). These three methods had proved successful in a previous evaluation of a different municipal website, yet we decided to replicate our study in order to investigate whether the three methods would reveal different results when applied to another municipal website with a different information architecture. The results of our study showed that, as in the previous municipal website evaluation, the three evaluation methods were largely comparable in terms of output. Nevertheless, we did find a number of differences between the present and previous municipal website evaluation regarding the workings of the three methods—differences that could be explained by the different information architectures of the municipal websites tested. This suggests that the three evaluation methods might indeed work differently depending on the nature of the website that is being evaluated, and calls for more research into the effect of task type on the validity of evaluation methods.  相似文献

The topic of effective crisis prevention and response is attracting significant interests from corporations and governments. It is evident that the nature within any crisis is unpredictable, erratic and difficult to prevent. Organizations are therefore preparing for unexpected events by outlining their crisis response strategies. The fact that crises may not repeat themselves and a given crisis solution might not be directly applicable to another crisis represents radical shifts in routines. As such, an organization may have to improvise when putting together a set of resources and capabilities for a response. This case study complements existing crisis management research that emphasizes both prevention and response by focusing on how an organization may adapt and deploy resources and capabilities accordingly. To meet the objective, the research draws upon an in-depth case study of Singapore's response tothe Asian Tsunami disaster in 2004. Our findings offer a useful contribution to organizations’ knowledge of mobilizing resources and capabilities during dynamic crisis situations. The case concludes with several research and practical implications.  相似文献

This paper reports on a case study of teachers’ expressions of their literacy-related professional development needs in a First Nations school located in Ontario, Canada. The paper construes the work of the teachers as “border work” and argues that their literacy teaching work was complex and tied to an ongoing legacy of colonialism. Four interrelated themes are discussed. The paper recommends improving compensation and job security for educators in First Nations schools and supporting them to see themselves as knowledgeable professionals who can entertain sophisticated notions of literacy that consider its relationship to situation including culture.  相似文献

Rural areas in the alpine regions suffer from dwindling student numbers. Differentiated instruction (DI) could help improve the teaching culture by allowing instructors to better adapt to heterogeneous student groups. At the beginning of a combined research and school improvement project, a survey of 162 teachers and 1180 students was conducted to obtain an overview of the types of DI that are currently practiced. In addition, we examined the school conditions that supported the implementation of DI. This cross-sectional study demonstrates a difference in practices between teachers with more- and less-developed DI cultures, and it was determined that team collaboration that includes pedagogical topics enhances teachers' use of DI.  相似文献

e-GovQual: A multiple-item scale for assessing e-government service quality   总被引:1,自引:0,他引:1  
A critical element in the evolution of governmental services through the internet is the development of sites that better serve the citizens' needs. To deliver superior service quality, we must first understand how citizens perceive and evaluate online. Citizen assessment is built on defining quality, identifying underlying dimensions, and conceptualizing measurements of these e-government services. In this article an e-gov service quality model (e-GovQual) is conceptualized and then a multiple-item scale for measuring e-gov service quality of governmental sites where citizens seek either information or service, is developed, refined, validated confirmed and tested.  相似文献

The Beijing World Conference on Women held in 1995 by the United Nations member states, approved strategies for improving women's access to and use of new communication technologies. The aim of this paper is to retrieve official statistics for the years 2000-2008 with regard to sex differences, gender and digital divide (specifically concerning telecommunication technologies) in two low-income economies in Sub-Saharan Africa, Kenya and Somalia. This paper reveals that official statistics on sex discrepancies and, the gender divide regarding access, use and benefits of telecommunications are still almost totally lacking for the countries in view. However, the digital divide is successively closing, and the telecommunication process in Kenya was quite rapid at the end of the period. Official statistics from Somalia are difficult to comprehend due to the absence of official data and a lack of evidence-based knowledge. Fifteen years after the Beijing Conference in 1995 there is still a lack of comprehensive statistics regarding new communication technologies for low-income economies such as Kenya and Somalia.  相似文献

In the discipline of library and information science (LIS), a qualitative analysis of the meaningful use of theory in contemporary scholarly literature is critical to helping scholars expand their repertoire of knowledge about various theories and helping them make informed decisions about how to skillfully integrate theory in their research. This study explored how theory was presented and talked about in seven prominent library science-focused journals from 2009 to 2011. Through a process of analytic induction, categories representing a continuum of theory talk were identified and their relationships examined. Three main types of theory talk in library research are defined, ranging from minimal (theory dropping), moderate (theory conversation), to major (theory generation). The categories and their relationships generate a rich discussion about the intensity and degree to which theory is being discussed and used in a less-examined subset of library and information science research journals. This research contributes both an explanatory structure and substantive discussion regarding theory use in library science to the professional literature.  相似文献
