Random sampling from the watson distribution

An envelope-rejection method is used to generate random variates from the Watson distribution. The method is compact and is competitive with, if not superior to, the existing sampling algorithms. For the girdle form of the Watson distribution, a faster algorithm is proposed. As a result, Johnson's sampling algorithm for the Bingham distribution is improved.     

Critical Business Ethics: From Corporate Self‐interest to the Glorification of the Sovereign Pater

Research in critical business ethics has demonstrated how economic self‐interest is the primary reason that businesses adopt nominally ethical practices. After reviewing this body of research, the authors propose that it can be further developed by questioning its conception of self‐interest, by exploring its non‐economic dimensions and by reconsidering the meaning of the ‘self’ that is said to have such interests. Drawing insights from feminist theory and political theology, the paper interrogates corporate business ethics as a public glorification of corporate power based on a patriarchal conception of the corporation. Genealogically rooted in early Christian ceremonial practices used to glorify God the Father, this is a glorification for the sake of glory rather than just for the sake of commercial ends. The authors further argue that corporate business ethics is rendered as the feminized servant of the sovereign corporate patriarch, always at hand to glorify the master. The meaning of corporate business ethics is hence one where the feminine is not absent, but rather is servile to a masculinity conceived in relation to domination, greatness and sovereignty. Collectively, this shows how the power wielded and desired by corporate business ethics far exceeds the pursuit of financial self‐interest; it is also related to modelling the corporation on a male God. The paper concludes by considering how research in critical business ethics can be extended through forms of inquiry that destabilize the ethical glorification of the corporation, and displace its masculinist privilege.     

Personal Network Correlates and Predictors of Homelessness for Injection Drug Users in Baltimore, Maryland

Injection drug users are at high risk for homelessness and human immunodeficiency virus (HIV) infection. This study sought to examine incidence rates and the social and economic antecedents of homelessness of impoverished inner-city injection drug users. Of the 569 participants, from a nontreatment sample who participated HIV prevention study, interviewed at baseline, 324 (57%) were reinterviewed 5.2 months later. At baseline 48% of the participants reported that they had been homeless in the past 10 years. Of the 324, 18% reported that at both interviews they had been homeless within the prior 6 months, 12% reported homelessness at baseline but not at follow-up, and 8% reported homelessness at follow-up but not at baseline. At baseline personal social support network characteristic of size of material aid and size of sex network was found to be associated with self-reports of homelessness. Baseline reports of presence of mother in personal network, size of material aid network, and network density were found to be associated with reports of homelessness at follow-up. These result suggest the need for alternative approaches to addressing issues of homelessness injection drug users.     

How Organizational Cognitive Neuroscience Can Deepen Understanding of Managerial Decision‐making: A Review of the Recent Literature and Future Directions

There is growing interest in exploring the potential links between human biology and management and organization studies, which is bringing greater attention to bear on the place of mental processes in explaining human behaviour and effectiveness. The authors define this new field as organizational cognitive neuroscience (OCN), which is in the exploratory phase of its emergence and diffusion. It is clear that there are methodological debates and issues associated with OCN research, and the aim of this paper is to illuminate these concerns, and provide a roadmap for rigorous and relevant future work in the area. To this end, the current reach of OCN is investigated by the systematic review methodology, revealing three clusters of activity, covering the fields of economics, marketing and organizational behaviour. Among these clusters, organizational behaviour seems to be an outlier, owing to its far greater variety of empirical work, which the authors argue is largely a result of the plurality of research methods that have taken root within this field. Nevertheless, all three clusters contribute to a greater understanding of the biological mechanisms that mediate choice and decision‐making. The paper concludes that OCN research has already provided important insights regarding the boundaries surrounding human freedom to act in various domains and, in turn, self‐determination to influence the workplace. However, there is much to be done, and emerging research of significant interest is highlighted.     

Decision Making in a Standby Service System*

A standby service option allows a firm to lower its risk of not having sufficient capacity to satisfy demand without investing in additional capacity. Standby service options currently exist in the natural gas, electric, and water utility industries. Firms seeking standby service are typically large industrial or institutional organizations that, due to unexpectedly high demand or interruptions in their own supply system, look to a public utility to supplement their requirements. Typically, the firm pays the utility a reservation fee based on a nominated volume and a consumption charge based on the volume actually taken. In this paper, a single‐period model is developed and optimized with respect to the amount of standby capacity a firm should reserve. Expressions for the mean and variance of the supplier's aggregate standby demand distribution are developed. A procedure for computing the level of capacity needed to safely meet its standby obligations is presented. Numerical results suggest that the standby supplier can safely meet its standby demand with a capacity that is generally between 20 to 50% of the aggregate nominated volume.     

The deterministic EPQ with partial backordering: A new approach

Several authors have developed models for the EOQ when only a percentage of stockouts will be backordered. Most of these models are complicated, with equations unlike those for the EOQ with full backordering. In this paper we extend work by Pentico and Drake [The deterministic EOQ with partial backordering: a new approach. European Journal of Operational Research 2008; in press] that developed equations for the EOQ with partial backordering that are more like those for the EOQ with full backordering to develop a comparable model for the EPQ with partial backordering.     

What's in a name? Current effects of family politicization on legislative candidates’ career start in Belgium

In this article we measure the effect of inherited political capital in the form of family politicization on legislative candidates’ recruitment age and early careers. We differentiate the concept of family politicization between a narrow (i.e., party political) and a broad (i.e., non-party-political) interpretation. Results indicate that narrow family politicization is the only type that plays a role in speeding up political recruitment. However, only the route to candidacy is affected by family politicization, whereas for the route to power other factors absorb this effect, mainly the candidates’ pre-electoral party engagement. This implies that candidates from narrowly politicized families do not merely rely on inherited political capital to get elected, which rejects a popular opinion. On the other hand, the result that parental talking and brokerage professions speed up the candidates’ election, indicate that the home environment does not play a neutral role in the early career path either.     

Prevalence,Characteristics, and Associations of Sexual Abuse with Sociodemographics and Consensual Sex in a Population-Based Sample of Swedish Adolescents

The purpose of this study was to investigate lifetime prevalence and characteristics of self-reported child sexual abuse and associations between child sexual abuse, gender, sociodemographic data, and consensual sexual experiences. A questionnaire was completed by 4,339 Swedish high school seniors. Three categories of child sexual abuse were studied: noncontact, contact without penetration, and penetrating child sexual abuse. Penetrating child sexual abuse was correlated with the most severe abuse characteristics. Students reporting child sexual abuse, especially penetrating child sexual abuse, were more likely to not be living with both parents, to have parents with lower socioeconomic status, and to have their first consensual intercourse at a young age. The study showed that distinct categories of child sexual abuse must be employed since each category shows a specific pattern concerning abuse characteristics, sociodemographics, and consensual sex.
