As American society grows more diverse and the issues that must be decided grow more complex, the need for new forums and better forms for public debate increases. Is computer conferencing likely to meet this need because of its potential for facilitating public participation in government? To shed light on this question, we constructed, ran, and observed a computer conference on recombinant DNA among four participants with no previous experience in using computers and no scientific training. Results indicate that not only was this topic successfully discussed by lay people in this way, but that the conferencing mode of discussion was preferred by certain types of people. Our experience also gave us insights that may improve management of computer conferences for inexperienced users. 相似文献

The environment industry has grown rapidly over the last decade. An increasing number of busines organizations are developing innovative products and processes which have neen generated by environmental concerns, increasing legislation for environmental protection and the regulation of industry's environmental impacts. There has been some research on barries to innovation and the problems affecting innovative product development in companies, but little ofthis has been applied to innovations developed for environmental protection, especially in the small firm. This paper provides empirical infomation on the problm experienced by engineers developing innovahe products and processes for environmental protection. A sample of 33 engineers, who were intmested in the competition The Environment Award for Engineers: replied to a postal questionnaire about the problas which thy had experienced in their environmental projects This is a competihon organized by the Engineering Council and sponsored by British Gas. The main aim the research was to explore the problems experienced by engineers during the developmat of environmental projects and in particular the different problems experienced by the engineers who were business owner-mangers and those who were employee engineers. The results show that the most jequent& experienced and most important problas are those concerned with securing financial backing and establishing the technical viability of the new product. Statistically significant differences were found between the most important problem expaaenced by employee engineers and business owner-mangers. 相似文献

This paper presents a cost performance comparison of different lot-sizing algorithms under multi-level rolling schedule conditions. Most multi-level studies have focused on fixed horizon problems, omitting an important characteristic of an operating MRP system. The results indicate that, under certain conditions, the computationally simple Silver-Meal heuristic provides lower lot-sizing costs than the Wagner-Whitin algorithm. In addition, cost modifications are introduced which greatly enhance the multi-level performance of these single-level lot-sizing heuristics. 相似文献

In order to add to the understanding of the role of franchising in entrepreneurship and to help franchise systems improve
efficiency, the constructs of organizational leadership, hope, organizational commitment, and service quality perceptions
of franchised managers and franchisees are differentiated in the current study. For scholars and practitioners, the dynamic
relationship between entrepreneurship, franchisees, and management is an important triangle which merits further investigation.
While the results offered only that managers and franchisees differed statistically in service empathy, differences were noted
across all areas which approached significance but was limited due to the small sample size. Implications for future research
are discussed. 相似文献

We introduce the interview assignment problem, which generalizes classic one‐to‐one matching models by introducing a stage of costly information acquisition. Firms learn preferences over workers via costly interviews. Even if all firms and workers conduct the same number of interviews, realized unemployment depends also on the extent to which agents share common interviewing partners. We introduce the concept of overlap that captures this notion and prove that unemployment is minimized with perfect overlap: that is, if two firms interview any common worker, they interview the exact same set of workers. 相似文献

This article explore performance issues in Australian public schools, using a two-stage DEA network model, which accounts simultaneously for both cost and learning efficiency levels. In the cost efficiency stage, different types of expenses and investments are employed to support a given number of students, teachers and administrative staff. In the learning efficiency stage, these groups of individuals help to produce important outputs related to performance in student tests and school rankings. Results indicate that Australian public schools are heterogeneous. Policy implications are also discussed. 相似文献

We consider the effect of mergers between firms whose products are not viewed as direct substitutes for the same good or service, but are bundled by a common intermediary. Focusing on hospital mergers across distinct geographic markets, we show that such combinations can reduce competition among merging hospitals for inclusion in insurers' networks, leading to higher prices (or lower‐quality care). Using data on hospital mergers from 1996–2012, we find support that this mechanism operates within state boundaries: cross‐market, within‐state hospital mergers yield price increases of 7%–9 % for acquiring hospitals, whereas out‐of‐state acquisitions do not yield significant increases. 相似文献
