Access to Information and Internal Structures of Partisan Groups: Some Notes on the Iron Law of Oligarchy*

Michel's notion of the inevitable and ironic transformation of groups with egalitarian intent into groups with oligarchical practices is examined through an analysis of thirty-four role playing partisan groups. Each group is a triad with an extended shared history or a history of equality that comes with friendship. Each group differentiated itself by selecting a representative to confront another student who played the role of a university dean. In nineteen of the groups the constituents obtained a news report of the outcome of those negotiations independent of their representative's report. In the other fifteen groups the constituents had to depend on their representative's report. In those groups that relied solely on their representative's report, oligarchical interrelations emerged. This contrasts with the news report groups who maintained egalitarian relationships while developing a political standpoint toward each other, the opposition and the future. We conclude that Michels' statement on organizational oligarchy is illuminated further by a consideration of an emergent monopoly of knowledge.     

Project LIFE: a partnership to increase physical activity in elders with multiple chronic illnesses

The authors describe a medical center-based randomized trial aimed at determining the feasibility and effectiveness of partnering patients and primary-care providers with an exercise health counselor. Study participants included 165 veterans age 70 years and older. The primary end point was change in physical activity at 3 and 6 months comparing patients receiving high-intensity physical activity counseling, attention control counseling, and usual care after receiving standardized clinic-based counseling. We noted a significant Group x Time interaction (p = .041) for physical activity frequency and a similar effect for caloric expenditure (p = .054). Participants receiving high-intensity counseling and usual care increased physical activity over the short term, but those with usual care returned to baseline by the end of the study. The intervention was well received by practitioners and patients. We conclude that partnering primary-care providers with specialized exercise counselors for age- and health-appropriate physical activity counseling is effective.     

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.     

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.     

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.     

Computation of the percentage points and the power for the two-sided Kolmogorov-Smirnov one sample test

Two recursive schemes are presented for the calculation of the probabilityP(g(x)≤S _n (x)≤h(x) for allx∈®), whereS _n is the empirical distribution function of a sample from a continuous distribution andh, g are continuous and isotone functions. The results are specialized for the calculation of the distribution and the corresponding percentage points of the test statistic of the two-sided Kolmogorov-Smirnov one sample test. The schemes allow the calculation of the power of the test too. Finally an extensive tabulation of percentage points for the Kolmogorov-Smirnov test is given.     

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.
