基于公平性的多用户OFDM系统自适应功率分配松弛算法

近期我国ETF市场出现了大规模异常赎回而导致资产规模大幅下降的异常现象。本文对这一异常现象分析后发现其主要原因可能是:(1)我国市场为弱式有效市场,被动式投资业绩不如主动式投资;(2)成份股经常出现涨停而导致投资者难以购买到涨停股份,制约了ETF的申购规模;(3)我国投资者不愿长期持有ETF,而只是把ETF当作波段操作工具。ETF资产规模大幅下降归根结底是由于投资者对ETF产品没有信心,也就是投资者对上市公司存有很大疑义,对股市缺乏信心。

Transforming Human Resource Management Systems to Cope with Diversity

The purpose of this study is to examine how workgroup diversity can be managed through specific strategic human resource management systems. Our review shows that ‘affirmative action’ and traditional ‘diversity management’ approaches have failed to simultaneously achieve business and social justice outcomes of diversity. As previous literature has shown, the benefits of diversity cannot be achieved with isolated interventions. To the contrary, a complete organizational culture change is required, in order to promote appreciation of individual differences. The paper contributes to this discussion by exploring the implications of this change for human resource management, and explaining how the systems of practices should be changed when they are directed to diverse groups. The model designed to test this notion includes: (1) demographic and human capital diversity as independent variables, (2) group performance (measured as innovation outcomes) as the dependent variable and, (3) the orientation of the strategic human resource management system as a potential moderator of this relationship. The main conclusion of the empirical analysis developed is that different patterns of human resource management practices can be used, depending on the type of diversity that the organization faces, and the specific effects that it wishes to manage. Concretely, three alternative management systems are identified in this paper, with different moderating effects. This result has interesting implications for human resource management professionals, explained in the last section. The limitations of this study are also discussed, as well as some issues that future research in this field should address.     

Varieties of Win–Win Solutions to Problems with Ethical Dimensions

The purpose of this article is to help educators and managers learn about a variety of win–win solutions to problems with ethical dimensions. The hope is that the larger the variety of win–win solutions we can consider, the higher the probability that we can find at least one that satisfies both ethical and material concerns. This article is motivated by the experiences of managers who have found that they need win–win solutions because it is very difficult to effectively advocate ethical solutions to problems that lose money or do not make money for their organizations. The purpose of the article is not to build theory or a theoretical taxonomy of win–win solutions, but to gather from eclectic theoretical and applied sources a variety of win–win solutions that can help solve problems with ethical dimensions. Examples of the types of win–win solutions are illustrated. Ethical problems with win–win solutions are also considered.
