By combining the Moriguti and Steffensen inequalities, we obtain sharp upper bounds for the expectations of arbitrary linear combinations of order statistics from iid samples. The bounds are expressed in terms of expectations of the left truncated parent distribution and constants that depend only on the coefficients of the linear combination. We also present analogous results for dependent id samples. The bounds are especially useful for L-estimates of the scale parameter of the distribution.  相似文献

The social responsibility of the business community has been widely discussed in the past few years. In retailing terms, it is often defined in terms of a need to behave ethically and to discharge a sectoral responsibility to provide society with the retail facilities it needs. This article argues that retailers could and should consider their responsibilities on a global scale and that their unique relationship with the consumer places them in a position where a major impact could be made on some of the important global issues facing us as we enter the 1990s.  相似文献

The British Company Voluntary Arrangement (CVA) is a relatively new debtor rehabilitation process intended to help financially troubled companies, particularly SMEs, resolve their difficulties without being forced into liquidation by secured creditors anxious to recover their funds. This paper is based on a survey conducted by Milman and Chittenden for the Association of Chartered Certified Accountants that is the largest and most comprehensive on the subject of British CVAs. It has three principal objectives: (i) to outline the defining characteristics of CVAs; (ii) to analyse the relationships between CVA performance and contextual factors; (iii) to provide policy recommendations based on those findings. Among other things we find that CVA success is most closely associated with sound fundamental prospects for recovery and supportive creditors. Our principal recommendation is that ways should be found of lowering the fixed costs of CVAs to make the procedure feasible for a larger number of small firms.  相似文献

The business community has failed to act on a fundamental given: a healthy political system is essential to a healthy economic system. A competitive economic system requires a competitive political system. Good citizens — motivated and informed — make effective leadership possible.Its ingredients require ending the escalating arms race among PACs in congressional races by reducing the amoung legislators may accept from PACs; by making small individual contributions count by matching them with the voluntary tax check off; disclosing direct and indirect lobbying expenses; and systematically reviewing our subsidy system by review spending, regulatory and tax preferences.David Cohen, president of the Social Development Corporation, a non-profit organization, served as president of Common Cause 1975–1981, and is an outstanding champion of human rights, including civil rights, consumer and urban affairs, and anti-poverty issues. Before joining the staff of Common Cause, in 1971, he worked as legislative representative for the Council for Community Action, the Industrial Union Department of the AFL-CIO and the Americans for Democratic Action. He also served as Director of Research and Collective Bargaining for the Upholsterers' International Union. A published author on the need to revitalize Congressional operations, Cohen was an Associate Fellow of Calhoun College at Yale University.  相似文献

This paper estimates the effect of persistence of innovation on employment in Spanish manufacturing firms during the period 1990–2008. Using GMM-system estimations, we study the importance of persistence of product and process innovation on employment growth according to the size of the firms. The results support that process innovation shows a positive effect on employment, especially for SMEs, while the effect of product innovation is not significant. The study also distinguishes that this effect appears in the contemporaneous year but it increases with the number of lags. This result confirms that compensation effects of process innovation may appear with a certain delay justifying the importance for SMEs of being persistent in innovation strategies to make them compatible with employment growth.  相似文献

Ethical lapses by employees can put organizations at substantial risk. Although improved compliance procedures can help limit this risk, successful efforts must extend beyond compliance to build a culture of organizational integrity. Recent changes in regulatory requirements and more stringent sentencing guidelines demand an integrated approach to ethical awareness, one that encompasses the four organizational practices of controls, clearly defined principles and purpose, core values, and culture. Inevitably, the most difficult of these is building a culture of high ethical standards that are reflected in day-to-day practice. To overcome the barriers to building organizational integrity, leaders must question key organizational practices while constructing a culture based on ethical behaviors.  相似文献

A line of research is emerging investigating the private sector impacts and dependencies on critical biodiversity and ecosystem services, and related business risks and opportunities. While the ecosystem services narrative is being forwarded globally as a key paradigm for promoting business sustainability, there is scarce knowledge of how these issues are considered at managerial level. This study thus investigates managerial views of corporate sustainability after the ecosystem services concept. We analyse interviews conducted with 20 managers from domestic and international forestry companies operating with a plantation-based business model in China. Content analysis was employed to analyse the data, with a focus on four key areas: (1) interviewee familiarity with the ecosystem services concept; (2) their views of corporate dependencies and impacts on ecosystem services; (3) related business risks and opportunities; and (4) viability of existing instruments and practices that can be employed in detecting and addressing business impacts and dependencies on ecosystem services. Through an inductive approach to the empirical findings, we refined a framework that holds operational value for developing company response strategies to ecosystem services impact/dependence assessment, ensuring that all issues are addressed comprehensively, and that related risks and opportunities are properly acknowledged.  相似文献
