The present study uses canonical analysis to examine the contingency model of organizations in the nursing home field. Data on environmental pressures and managerial practices relevant to the decision-making process are analyzed. Results support the theory that managerial practices are contingent on environmental pressures. The implications of these results for health-care decision makers and for future assessments of managerial-environmental relationships are discussed. 相似文献

Small business loan applications have not been evaluated successfully by traditional methods. This paper explores the possibility of using three types of nonfinancial ratio variables (owner, firm, and loan characteristics) to predict whether a small business will pay off or default its loan. The owner and loan variables were better predictors of loan success than the firm variables. 相似文献

适于大视场空间相机应用的高性能ADV212控制器 总被引:1,自引:0,他引:1
针对现有基于ADV212压缩系统的ADV212控制器难以满足空间TDICCD相机的应用,提出了一种适于大视场空间TDICCD相机的高性能ADV212控制器。首先,分析了ADV212工作原理,结合CCD数据特点,提出了Custom-specific模式工作机制,在该机制下,使用乒乓操作的SDRAM构造图像帧,并以流水线作业的方式实现单片ADV212处理5通道CCD数据。最后,使用地面检测设备对ADV212控制器进行了试验验证。结果表明,ADV212控制器能快速稳定地工作,压缩一帧图像仅需7.68 ms。在压缩比指标2:1~32:1内,PSNR均在30 dB以上,在正常工作压缩比为1 bpp时平均PSNR提高了2.49 dB。该控制器满足了空间相机压缩系统的应用。 相似文献

This paper presents a minimum-cost methodology for determining a statistical sampling plan in substantive audit tests. In this model, the auditor specifies β, the risk of accepting an account balance as correct when it is not, according to audit evidence requirements. Using β as a constraint, the auditor then selects a sampling plan to optimize the trade-off between sampling costs and the costs of follow-up audit procedures. Tables to aid in this process and an illustration are provided. 相似文献

现代企业制度使企业所有权与经营控制权分离,也使剩余索取权与经营控制权分离,进而产生了委托代理关系,出现了代理成本。合理的股权结构会使代理成本趋于最低化。减持国有股,培育管理层控制体系及各类法人股东,使国有控股公司实现股权多元化,是优化公司治理主体,构建有效股权治理结构的基本策略。 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

This article defines Active Citizenship within a European context as a broad range of value based participation. It develops
a framework for measuring this phenomenon which combines the four dimensions of Protest and Social Change, Community Life,
Representative Democracy and Democratic values. The European Social Survey 2002 is used to populate the framework as this
survey provided the best data coverage available and covered 19 European Countries. In total 61 indicators were selected.
A composite indicator (CI), The Active Citizenship Composite Indicator (ACCI), is built using the framework provided and using
experts’ weights. In addition, the robustness of the results is tested using sensitivity analysis. The limitations to the
ACCI are explained in terms of the limitation of the data availability in particular concerning the new forms of participation
and less organised forms of participation. Nevertheless, ACCI proved to be statistically robust and reliable and proved to
be a useful tool for monitoring levels of citizenship in Europe. The results of ACCI exhibit interesting and quite distinct
regional patterns. The results showed that the Nordic countries, and in particular Sweden, have the highest rate of Active
Citizenship, followed by Central Europe and Anglo-Saxon countries. Mediterranean countries are next followed by Eastern European
countries that close the ranking.

Determining priority importance is a matter of concerns among the organization to improve their performance. One of the important
aspects that should be considered by the organization is management of human resources, comprising of members who have their
own family life. In this paper, we deliver a new perspective for organization to provide priority importance for their members
with respect to family matters in order to inculcate the sense of belonging in the organization. To be effective in considering
family matters in the organizational policy making, closer look of family characteristics are required. The idea of translating
several family characteristics as quality variables and applying the quality function deployment (QFD) method to these variables
could present a new way of improving the decision making in the organization by considering the process of decision in the
family. Quality function deployment for family (QFDF) produces a friendly interpretation of a highly complex and intangible
matters around family life; thus, making the assessment of a family easier. QFD is applied on the data gathered from a questionnaire
survey based on 1,213 families in West Malaysia, Malaysia. Twelve variables are identified as voice of family, where seven
of them are found to have the highest priority of importance. These variables could also be translated into quality variables
in the context of organization, the strategy of improvement for the family could be interpreted as strategy for improvement
in the organization. Furthermore, the results of this study provide suggestion to improve actions for managing human resource.
In the discussion, three most high ranked variables from both perspectives of family and organization are considered. 相似文献
