This essay explores the controversy over peer-to-peer (p2p) software, examining the legal and ethical dimensions of allowing software companies to develop p2p technologies. It argues that, under the Supreme Court’s ruling in the Sony betamax case, technology developers must be accorded the freedom to innovate and develop technologies that are capable of substantial noninfringing uses. This doctrine, known as the Sony doctrine, provides an important safe harbor for technological development, including p2p. The safe harbor, however, does not immunize conduct beyond the design, sale, or supply of the product. For other conduct that falls outside the Sony safe harbor, the traditional standards of secondary liability apply.  相似文献

A model of information technology (IT) ethical work climates is presented. Using these ethical work climates and data collected from a national mail survey of Association for Computing Machinery (ACM) members, empirical measures were developed and evaluated. A mailing of 2446 questionnaires was sent to ACM members and 136 usable responses were returned (5.6%). Using these data, an exploratory factor analysis was performed using principle components analysis to identify the IT ethical work climates from the data. Six of these work climates were identified as predicted by the model. Two ethical work climates that were combinations of the proposed climates were also identified.From the results of the exploratory factor analysis, a confirmatory factor analysis was performed using Calis in PC SAS version 8. The purpose of this analysis was to evaluate the overall fit of these measures to the data and evaluate the psychometric properties of the measures. The fit of the IT ethical work climates model was acceptable. The psychometric properties of these measures were good. Based on these results, conclusions, limitations of the study, and directions for future research are proposed.  相似文献

Resource extraction companies worldwide are involved with Indigenous peoples. Historically these interactions have been antagonistic, yet there is a growing public expectation for improved ethical performance of resource industries to engage with Indigenous peoples. (Crawley and Sinclair, Journal of Business Ethics 45, 361–373 (2003)) proposed an ethical model for human resource practices with Indigenous peoples in Australian mining companies. This paper expands on this work by re-framing the discussion within the context of sustainable development, extending it to Canada, and generalizing to other resource industries. We argue that it is unethical to sacrifice the viability of Indigenous cultures for industrial resource extraction; it is ethical to engage with indigenous peoples in a manner consistent with their wishes and needs as they perceive them. We apply these ideas to a case study in the coastal temperate rainforest of Clayoquot Sound, British Columbia, Canada. In this case a scientific panel comprised of Nuu-Chah-Nulth elders, forest scientists and management professionals, achieved full consensus on developing sustainable forest practice standards by drawing equally on Indigenous traditional ecological knowledge and Western science in the context of one of the most heated and protracted environmental conflicts in Canadian history. The resulting sustainable forest practice standards were later adopted by leading forestry firms operating on the coast. Our analysis of this scientific panels success provides the basis for advancing an ethical approach to sustainable development with Indigenous peoples. This ethical approach is applicable to companies working in natural resource industries where the territories of Indigenous peoples are involved.David Lertzman Ph.D. is Adjunct Assistant Professor of Environmental Management and Sustainable Development and Senior Associate with the TransCanada International Institute for Resource Industries and Sustainability Studies at the Haskayne School of Business, University of Calgary. He teaches courses on Sustainable Development With Indigenous Peoples at the Graduate and Undergraduate levels, and in the MSc Program in Sustainable Energy Development for Latin America and the Caribbean. Dr. Lertzman also teaches a Wilderness Retreat on Leadership for Sustainable Development in the MBA program. He is a private consultant and has worked in many Indigenous communities, mostly in Western Canada.Harrie Vredenburg Ph.D. is Professor and Suncor Energy Chair in Competitive Strategy and Sustainable Development at the Haskayne School of Business at the University of Calgary where he is also Director of the TransCanada International Institute for Resource Industries and Sustainability Studies. He teaches in Haskaynes MBA and PhD programs.

Many tasks and decisions in business, including management consulting, are performed in group settings. Computer-mediated communication (CMC) tools (e.g., Lotus Notes) are increasingly being used by businesses to support teams in a variety of settings. Considerable research in information systems has demonstrated the advantages of electronic brainstorming (EBS) for generic tasks involving only divergent thinking. However, it is unclear whether the benefits of CMC extend to tasks that require both divergent and convergent processes. Per task–technology fit theory (TTF) (Zigurs and Buckland 1998), the use of computer-based group communication support tools, including chat systems in wide-spread use today, may be less effective for convergent processes than for divergent processes. This study experimentally compares the performance of computer-mediated and face-to-face (FTF) teams on tasks requiring both divergent and convergent processes. Consistent with theoretical predictions, the results revealed that computer-mediated teams outperformed FTF teams in the divergent aspects of the tasks, while FTF teams outperformed computer-mediated teams in the convergent aspects of the tasks.  相似文献
