This paper is concerned with planning work-center capacity levels in manufacturing firms that employ a material requirements planning (MRP) system. It presents four procedures for developing work-center capacity plans designed to insure the production of components and assemblies as specified by the MRP plan and the master production schedule (MPS). These procedures (capacity planning using overall factors, capacity bills, resource profiles, and capacity requirements planning) are compared using simulation analysis. The results indicate that the performance of a procedure when measured against the MPS depends on the operating conditions of the manufacturing system. The results also indicate that the choice of a particular procedure often represents a compromise among the benefits of improved MPS performance, the costs of preparing and processing data, and the premium expenses required for more frequent adjustments in work-center capacity levels. 相似文献

第一次世界大战前,对现代社会和文化发展的忧虑便普遍存在———这一点在德国表现得尤为明显。德国、法国、英国及美国的历史学家都在期望战后的世界不要完全不同于战前的秩序。战前的迹象表明,人们同时也在作一些缓和紧张局势的尝试,在历史学家中,这种情况就更为显著。德国学界的国际交往在继续,并且呈扩大的趋势。然而,随着战争的爆发,友谊变成了仇恨,不仅针对敌对国家,也针对它们的历史学家。战争双方都认为,这是一场两种文化间的战争。一战期间,两大阵营的历史学家立场和行为有着很大的相似性,即不论战前他们在政治问题上分歧多么大,一旦战争爆发,他们都几乎无条件地支持战争,尽管这些分歧只是被暂时搁置在一边,这种情形在德国尤为突出。然而,毫无疑问也有一些不同之处。在支持与反对战争的双方之间,分歧与一致同时存在。值得注意的是,在德国,战争对历史编纂学的影响很小,历史学家都不愿接受战争带来的新的现实。一战后,德国的历史学家很少再与其他国家,特别是法国和美国历史研究的新潮流发生联系;由于抵制变迁,德国历史学变得越来越和国际学术界无关。 相似文献

Based on a cohort of young Austrians of Turkish descent, this paper links the debate on the integration of the second generation (or the lack thereof) with the controversial discourse about the potential usefulness and risks of new media and technologies, specifically the Internet. Various studies have concluded either that the new media and technologies are positive integrative aspects of the society or have devastating impacts on different groups. On the one hand, the Internet allows young people to discover new experiences and gain additional often unorthodox knowledge; on the other hand, observers have warned about the segregating effects of new technologies. A ?digital divide“ has been opened between privileged users and the underprivileged masses, according to these more cautious voices. This divide has caused social deprivation and disintegration amongst the most vulnerable groups, in particular, older people, economically insecure groups and immigrants. Thus, various media life-styles establish a continuum between a media and information elite on the one end and the entertainment under-class on the other. Semi structured interviews with young Turks in Vienna show the positive and negative effects of playing Online Role Playing Games on the Internet in opposition to so-called Social Network Sites such as Netlog. 相似文献

This paper examines the impact of relative income on income satisfaction with given absolute income. We conducted an experiment in China where participants earned three different levels of income according to their relative performance in a task. While the treatment group was informed about their relative income, the control group only knew their own absolute income. We found that while controlling for absolute income and other factors, information about relative income increases the satisfaction of the high-income group and reduces the satisfaction of the low-income group. Relative income may interact with individual characteristics, such as gender, to affect income satisfaction. We also found that relative income treatment significantly increases income satisfaction inequality, primarily by causing social comparisons among different income groups, which has some welfare implications. 相似文献

Internet technology has become an informational resource for most health care consumers. Online information, discussion, and support groups, in the form of message boards, listservs, and chat rooms are emerging as parts of virtual self-health-care network. This paper examines the extent to which participation in online health discussion groups was reported to be helpful in increasing medical knowledge and in enhancing the participatory patient role of health care consumers in interaction with health care service professionals. Data for this study was collected from 350 patients who participated in Internet discussion groups for cancer patients. The findings of the study indicated the important impact of Internet health discussion groups on health care management practices as perceived by health care consumers, including empowerment through knowledge and proactive participation in cancer care management. This research contributes to understanding the patient perspective and assesses the perceived importance of Internet groups by health care consumers. 相似文献

The purpose of the current study was to assess staff preference for how data were displayed on graphs. Specifically, preference for line versus bar graphs was assessed, as well as preference for data displayed as one date in time versus multiple dates showing performance trends. A secondary purpose of the study was to assess staff comprehension of the data presented across different graphic displays. Participants included 60 entry-level direct care staff and 25 seasoned therapists. Therapists had more advanced training in applied behavior analysis than the direct care staff. The vast majority of direct care staff preferred data depicted as a bar graph versus data depicted as a line graph, even preferring a single bar graph over a time-series line graph. The therapists preferred time-series line graphs to bar graphs. Most staff demonstrated understanding of the data, regardless of how it was depicted. 相似文献

The purpose of this research was to determine what behaviourally distinguishes effective and ineffective managers within a Moroccan Higher Education Institution (HEI). The critical incident technique (CIT) was the methodology deployed to collect data from participants in terms of how they perceive managers as either effective or ineffective. The collected data (CIs) were subjected to content and thematic analysis that resulted in derived positive and negative behavioural statements (BSs). A total of 42 participants/informants were interviewed and revealed a total of 418 CIs, of which 189 were positive CIs and 229 were negative. The analysis revealed a total of 49 BSs, of which 19 were positive and 30 were negative behavioural indicators. The findings of this investigation bring empirical evidence to understand what and how managers are perceived as effective or ineffective in the Moroccan academic context and, therefore, adds to the literature. The information obtained can also provide rich information/knowledge that can be used as a basis to address the behavioural developmental needs of managers in HEIs. This research adds value by following by following two previous replication studies in a French and a Hungarian HEI; moreover, this study is the first to be conducted in the Moroccan/North African region. 相似文献

Coopetition has the potential to improve entrepreneurship and innovation. It will be prevalent in coworking-spaces building a growing field for individual and corporate entrepreneurship. The individuals’ physical closeness in the professional and social space of the coworking-space eases multifaceted transfers of explicit and implicit knowledge, stimulating creation, transfer, overhaul, and implementation of entrepreneurial ideas. While entrepreneurs in these coworking-spaces collaborate on sharing knowledge and resources and on finding creative ideas from which can breed new venture concepts, they simultaneously compete on the appropriation of values. Thus, entrepreneurs in coworking-spaces face coopetitive tensions of creating and appropriating the values. Based on interview data and secondary sources, this paper explains four different prototype institutions of coworking-spaces: the corporate coworking-space, the open corporate coworking-space, the consultancy coworking-space, and the independent coworking-space. Study explains different tensions of value creation and appropriation that occur within the coopetition in the different forms of coworking-spaces. 相似文献

Although human trafficking is recognized as a major human rights violation, there is limited evidence regarding the vulnerabilities that contribute to female adolescents’ risk of being forced or coerced into the sex trade. Vulnerabilities such as gender‐based violence, economic and social inequalities have been shown to shape the risk of sexual exploitation among adolescents. In‐depth interviews (n=18) with current sex workers who reported being deceived or forced into the sex trade as adolescents (<17 years old) were analysed to explore their experiences of migration and mobility in Mexico. Driven by socio‐economic and vulnerabilities in home communities, adolescents often engaged in internal migration and mobility to other Mexican communities and states. Migration and mobility further predisposed them to social isolation, economic hardship and abuse, which were used as tools to trick them into the sex trade. Policies that support safer migration for adolescents in origin, transit, and destination communities are needed. 相似文献
