Underprotection of Unpredictable Statistical Lives Compared to Predictable Ones

Existing ethical discussion considers the differences in care for identified versus statistical lives. However, there has been little attention to the different degrees of care that are taken for different kinds of statistical lives. Here we argue that for a given number of statistical lives at stake, there will sometimes be different, and usually greater, care taken to protect predictable statistical lives, in which the number of lives that will be lost can be predicted fairly accurately, than for unpredictable statistical lives, where the lives are at stake because of a low‐probability event, such that most likely no one will be affected by the decision but with low probability some lives will be at stake. One reason for this difference is the statistical challenge of estimating low probabilities, and in particular the tendency of common approaches to underestimate these probabilities. Another is the existence of rational incentives to treat unpredictable risks as if the probabilities were lower than they are. Some of these factors apply outside the pure economic context, to institutions, individuals, and governments. We argue that there is no ethical reason to treat unpredictable statistical lives differently from predictable statistical lives. Moreover, lives that are unpredictable from the perspective of an individual agent may become predictable when aggregated to the level of a societal decision. Underprotection of unpredictable statistical lives is a form of market failure that may need to be corrected by altering regulation, introducing compulsory liability insurance, or other social policies.     

The VL control measure for symmetric networks

In this paper we measure “control” of nodes in a network by solving an associated optimisation problem. We motivate this so-called VL control measure by giving an interpretation in terms of allocating resources optimally to the nodes in order to maximise some search probability. We determine the VL control measure for various classes of networks. Furthermore, we provide two game theoretic interpretations of this measure. First it turns out that the VL control measure is a particular proper Shapley value of the associated cooperative network game. Secondly, we relate the measure to optimal strategies in an associated matrix search game.     

The Alliance in Relationship Education Programs

Couple relationship education (CRE) programs are associated with positive romantic relationship outcomes; however, the mechanisms by which these gains occur are less understood. The current study (122 couples) utilized actor–partner modeling to examine the association between the therapeutic alliance and dedication and negative and positive communication for racial/ethnic minority couples. Additionally, we examined whether gender and delivery format moderated these relationships. Results demonstrated that both men's and women's alliance scores were significantly related to their own outcomes. Higher ratings of alliance were related to partner outcomes for men only. The association between partners' alliance and dedication outcomes was stronger within the group format as compared to the couple format. Implications for leaders of CRE programs are offered.     

华宴:十一世纪的性别与文体

中国雅正文化形成于9—11世纪。此时,一个另类的话语空间开始出现,并把传统诗歌形式排斥在外,通过这种排斥,使传统诗歌成为雅正的。这个另类话语空间即本文所谓华宴。北宋初年晏殊的家宴是一个典范。这类诗酒集会有严格的规矩,通常是歌伎的演唱暗示和挑动欲望,但她们的表演总是突然中止,女性被罢遣,接下来的重心转向属于男性社会的创作:雅正的诗传统。他们的词里关于丧失与渴望的意象,实际上正好体现了社会对词曲表演本身的限制,因而成为合法的。另一方面,词体中文言和白话语言层次的参差对照及突出转换,也暗示了欲望的中止和诗意的产生。如此,雅正文学在其自身的形成中获得了一个影子,它在词中存在,容纳了在雅正的诗文中不能表现的东西,并使其他一切都变得缺乏意义。     

A table of normal integrals

Integrals of functions of the univariate, bivariate, trivariate and multivariate normal densities are given. Both indefinite and definite integrals are included.     

New representations of the noncentral chi-square density and cumulative

Representations of noncentral chi-square cumulative distribution function and probability density function are reviewed and new repre¬sentations are given. One representation of the cdf in terms of an integral is easily computed on any machine which has an accurate algorithm for computing the normal cdf.     

The risk of partner aggression research: impact of laboratory couples conflict protocols on participants

The impact of male-to-female intimate partner violence (IPV) research on participants is unknown. A measure of impact was given to participants in an IPV study to assess systematically the impact of completing questionnaires, engaging in conflict conversations, and being interviewed individually about anger escalation and de-escalation during the conversations. Participants completed a six-question, Likert-scaled impact measure. Both male and female participants rated the impact of the study as helpful to them personally and to their relationships. Female participants rated different segments of the study as more helpful to themselves and their relationships, while male participants did not find any segment of the study to have a different impact than other segments.     

Communication between Managers and Staff in the NHS: Trends and Prospects

The importance of the role of communication in the success of individual performance in social and business life is now widely recognized. Within organizations, effective internal communication between managers and staff is vital to organizational success. This is particularly so during periods of change, when staff uncertainty increases and there is an increased need for greater amounts of information and more frequent communication. Staff in the NHS have recently experienced some quite dramatic changes in their working practices. This paper therefore examines the current state of communication within the NHS and the implications which this poses for the overall functioning of the organization. In particular, the relationship between communication and the motivation of staff is described. The nature of communication audits, the main research approach used to assesses communication effectiveness, is then delineated, and areas of the NHS chosen for analysis by this means are proposed. The results of a series of audits are summarized. Problems in information flow, use of information sources and channels, the timeliness of information exchanged, the extent to which people send information to each other and the quality of working relationships are identified. The implications of these findings for the NHS and general views of management are considered.
