The Relationship Between Old-Fashioned and Modern Heterosexism to Social Dominance Orientation and Structural Violence

This study proposes that broader social systemic factors could have a role in the perpetuation of two types of heterosexism. Old-fashioned and modern heterosexism are discussed and differentiated. The roles of social dominance orientation and the acceptance of structural violence in the maintenance of heterosexism are explored. Results indicated that social dominance orientation and the acceptance of structural violence predicted the level of old-fashioned and modern heterosexism in a sample of 129 people. Acceptance of structural violence better predicted both modern and old-fashioned heterosexism than did social dominance orientation. Such relationships highlight the possibility that social systemic beliefs may create and support heterosexism.     

Existence and Uniqueness of Maximal Reductions Under Iterated Strict Dominance

Iterated elimination of strictly dominated strategies is an order dependent procedure. It can also generate spurious Nash equilibria, fail to converge in countable steps, or converge to empty strategy sets. If best replies are well–defined, then spurious Nash equilibria cannot appear; if strategy spaces are compact and payoff functions are uppersemicontinuous in own strategies, then order does not matter; if strategy sets are compact and payoff functions are continuous in all strategies, then a unique and nonempty maximal reduction exists. These positive results extend neither to the better–reply secure games for which Reny has established the existence of a Nash equilibrium, nor to games in which (under iterated eliminations) any dominated strategy has an undominated dominator.     

On qualitative multi-attribute group decision making and its consensus measure: A probability based perspective

This paper focuses on qualitative multi-attribute group decision making (MAGDM) with linguistic information in terms of single linguistic terms and/or flexible linguistic expressions. To do so, we propose a new linguistic decision rule based on the concepts of random preference and stochastic dominance, by a probability based interpretation of weight information. The importance weights and the concept of fuzzy majority are incorporated into both the multi-attribute and collective decision rule by the so-called weighted ordered weighted averaging operator with the input parameters expressed as probability distributions over a linguistic term set. Moreover, a probability based method is proposed to measure the consensus degree between individual and collective overall random preferences based on the concept of stochastic dominance, which also takes both the importance weights and the fuzzy majority into account. As such, our proposed approaches are based on the ordinal semantics of linguistic terms and voting statistics. By this, on one hand, the strict constraint of the uniform linguistic term set in linguistic decision making can be released; on the other hand, the difference and variation of individual opinions can be captured. The proposed approaches can deal with qualitative MAGDM with single linguistic terms and flexible linguistic expressions. Two application examples taken from the literature are used to illuminate the proposed techniques by comparisons with existing studies. The results show that our proposed approaches are comparable with existing studies.     

Social Dominance in Romantic Relationships: A Prospective Longitudinal Study of Non-verbal Processes

The study of social dominance has a long tradition within the peer relationships literature, but rarely has the topic been investigated observationally and longitudinally within other salient close relationships. The present study investigated the role of experiences in social relationships and adjustment indices in childhood in predicting later observed non‐verbal social dominance behaviors in the context of romantic relationships in emerging adults. Analyses from a subsample (N = 70) from a 29‐year prospective longitudinal study revealed links between early peer behavior and subsequent romantic relationship interactions for men and women. Non‐verbal social dominance behaviors were concurrently associated with poor romantic relationship quality, conflict, and physical and verbal aggression within the dyad. Both childhood externalizing and internalizing behaviors significantly predicted non‐verbal social dominance behaviors in the romantic partner interactions.     

Willingness to Pay for Risk Reduction and Risk Aversion without the Expected Utility Assumption

By means of minimal assumptions on the individual preferences, I show that the Willingness To Pay (WTP) for both a FSD and SSD reduction of risk is the sum of a mean effect, a pure risk effect and a wealth effect. As a result, the WTP of a risk-averse decision maker may be lower than the WTP of a risk-neutral one, for a large class of individual preferences’ representation and a large class of risks.     

零售商主导下促进绿色产品需求的联合研发契约协调研究

针对绿色环保产品价格过高,阻碍其成为主流消费品这一现实问题,在绿色经济背景下,探讨零售商向负责绿色研发成本投入的制造商提供不同联合研发契约时的供应链均衡策略和协调问题。以零售商主导的双边垄断型绿色供应链为研究对象,在考虑消费者环保意识、产品绿色度水平、价格等多种因素影响需求的基础上,分别探讨批发价契约、成本分担契约和两部制契约对绿色产品需求、供应链成员利润及渠道利润的影响。结果表明,成本分担契约无法实现供应链成员利润的Pareta改进;一定条件下,两部制契约可以实现供应链成员利润的双赢,并提高绿色产品的市场需求。此外,虽然消费者环保意识的提高并不总是会带来绿色产品市场需求的增加,但却总是会使得绿色供应链的利润提高;并且较高的消费者环保意识将激励企业追求一个较低的绿色成本系数,从而促使企业积极进行绿色技术创新努力。     

The social construction of the medical malpractice crisis: A case study of Massachusetts physicians

This study used observations from the 1985 Massachusetts malpractice insurance rate hearings, semistructured interviews conducted in 1985–1986, a survey of Massachusetts physicians in February 1988, and newspaper reports from theBoston Globe. Physicians and the Massachusetts Medical Society have promoted the medical malpractice crisis as an economic one. The after-expense income of most physicians, however, has remained relatively constant. The more serious threat to physicians appears to be the reduction of their autonomy. It is concluded that the medical malpractice crisis has been socially constructed in economic rather than autonomy terms because, traditionally, economics has been a more acceptable basis for labor unrest in the United States. Constructing malpractice as an economic crisis presents a more viable argument for stemming social change adverse to the medical profession.An earlier version of this paper was presented at the 57th annual meeting of the Eastern Sociological Society, May 1987, Boston, Massachusetts.     

Estimating density ratio with application to discriminant analysis

The estimator ? for the ratio of densities based on grade transformation is introduced. Under certain conditions the strong uniform consistency of ? is proved and its asymptotic law is determined. The result is applied to study the behaviour of divergence curve used in discriminant analysis.     

由"支配地位"到"严重阻碍有效竞争"——欧盟企业合并控制法的实体标准改革评析

欧盟企业合并控制法的实体标准担负着判断企业合并是否限制相关市场中有效竞争的任务,是该法的重要组成部分.在1989年通过的4064/89号条例中,欧盟实行的是支配地位标准.但是,由于在实践中存在着缺口等问题,欧盟于2003年通过了139/2004号条例,采纳了严重阻碍有效竞争标准(significant impediment to effective competition, SIEC),达到了克服支配地位标准缺陷的目的.     

Generating Ordered Families of Lorenz Curves by Strongly Unimodal Distributions

From any strongly unimodal density on the real line, it is possible to generate a one-parameter family of Lorenz curves. The resulting families of Lorenz curves are Lorenz ordered with respect to the indexing parameter. Symmetry of the unimodal density results in the generation of symmetric Lorenz curves. A related characterization of the normal distribution is presented.
