We consider the problem of minimax-variance, robust estimation of a location parameter, through the use of L- and R-estimators. We derive an easily checked necessary condition for L-estimation to be minimax, and a related sufficient condition for R-estimation to be minimax. Those cases in the literature in which L-estimation is known not to be minimax, and those in which R-estimation is minimax, are derived as consequences of these conditions. New classes of examples are given in each case. As well, we answer a question of Scholz (1974), who showed essentially that the asymptotic variance of an R-estimator never exceeds that of an L-estimator, if both are efficient at the same strongly unimodal distribution. Scholz raised the question of whether or not the assumption of strong unimodality could be dropped. We answer this question in the negative, theoretically and by examples. In the examples, the minimax property fails both for L-estimation and for R-estimation, but the variance of the L-estimator, as the distribution of the observation varies over the given neighbourhood, remains unbounded. That of the R-estimator is unbounded. 相似文献

This article engages the question—what is the right business‐society relationship? We consider three perspectives that seek to address the relationship: corporate social responsibility (CSR), social entrepreneurship (SE), and conscious capitalism (CC). We take a macroapproach considering how commentary about these approaches establishes a direction for corporate practice and its relationship to key stakeholder groups. We argue that these perspectives are ‘D'iscourses that provide arguments for and articulations about the direction of corporate practice and the business‐society relationship. To organize our review of each perspective, and focus our critique, for each we highlight (a) drivers and influencers, (b) core assumptions and defining features, and (c) approaches and exemplars. Although distinct, all emphasize effective business practices as key to meeting social needs. CSR suggests legitimizing business practice; SE relocates business practices; and CC seeks to reimagine/rehabilitate business for social good. Ultimately, we conclude that these Discourses lack a clear communicative focus in terms of decision making within these organizations. We attend to this and other implications, and offer avenues for further research. 相似文献

We examine the role of managers in controlling the positive impact of stakeholder management (SM) on firm financial performance (FP) in the long term. We develop and test competing hypotheses on whether managers act as “good citizens” or engage in “self‐dealing” when allowed greater discretion. We test our assertions using dynamic panel data analysis of a sample of 806 U.S. public firms operating in 34 industries over 5 years (2005–2009). Our results indicate a nuanced influence of managerial discretion contexts on the SM‐FP relationship. We infer that given more latitude in decision making, as long as the “going is good” managers act as good citizens, but otherwise they revert to managerial self‐dealing. In light of our results, firms designing governance mechanisms to encourage managers to balance the needs of both shareholders and stakeholders must remain cognizant of contextual contingencies. 相似文献

This paper describes a systemic, trauma and attachment model for a parenting program for fathers in residential substance abuse treatment. It emphasises the complex nature of delivering parenting programs in this context and the importance of going beyond simple linear principles of reward and punishment, upon which many other parenting programs are predicated. 相似文献

The lack of attention in academic discourse to representations of disability in films from the Middle East has led to an incomplete picture of representations of disability in global cinema. For instance, the diverse meanings of disability in Iranian cinema and the influence of disability on the emergence of Iranian New Wave cinema have been almost completely ignored by scholars. A number of award-winning films from Iran have featured disability as central to their narratives – such as The House is Black (1963), Taste of Cherry (1997), The Color of Paradise (1999), The Willow Tree (2005), and The Painting Pool (2013). Disability in these films serves alternatively as a symbol of spiritual possibility, a mark of marginalization, and a covert social critique. These films examine the emotional, physical, and social implications of disability, while celebrating the cultural power of film to challenge social, religious, and artistic barriers. 相似文献
