THE IMPLICATIONS OF CHANGING EDUCATION AND GENDER INPUTS FOR POLICE DECISIONMAKING AND SUPERVISORY ROLES

This article reports the results of a survey of 43 Queensland police officers, half in supervisory roles and half immediately prior to induction. The purpose of the survey was to identify gender and educational differences between groups, and to identify any effect that these differences may have had on attitudes toward decision-making within the sample. The results were compared to a similar survey of American police chiefs. Attitudes toward decision-making were found to be similar among all groups with the exception of the perception of the ability to implement change. This was found to be significantly higher among women and those with a tertiary education. It was also suggested that female officers have the potential to excel in police managerial positions due to higher education levels, but they are currently seriously under-represented in supervisory and managerial positions.     

The influence of race, ethnicity, class, and sexual politics on lesbians' body image

Based on interviews conducted with eight lesbians, this paper explores how the intersection of gender, sexual identity, race, ethnicity, and class affect lesbians' feelings about their bodies. Their responses suggest that, while being female has a strong effect on lesbians' feelings about their bodies, issues of race, acculturation, and class also affect body image. Lesbian feminism and S/M politics also appear to play a significant role in lesbians' body image. These findings highlight the limitations of existing theories about body image and call for a more complex theory incorporating a more diverse range of experiences.     

Intimate Partner Violence and Social Relational Theory: Examining the Influence of Children and Important Others on Mothers' Transition Out of Violent Relationships

Interviews with survivors of intimate partner violence were conducted to gain information on the transition from violent relationships to new non‐violent relationships. A subset of this data was re‐analysed using Social Relational Theory to gain further insight into the roles of children and important others who were identified as impacting this transition for mothers who had exited violent relationships. This paper reviews two major themes discovered during the SRT analysis that were inherent in the women's experiences: (i) agency of children, family, peers and community and (ii) power. In addition, this paper suggests implications for research, intervention and psychotherapeutic practice.     

A General Statistical Framework for Multistage Designs

Abstract. The efficiency of observational studies may be increased by applying multistage sampling designs. It is, however, not always transparent how to construct such a design to obtain increased efficiency. We here present a general statistical framework for describing and constructing multistage designs. We also provide tools for efficiency and cost‐efficiency comparisons, to facilitate the choice of sampling scheme. The comparisons are based on Fisher information matrices and the results are presented in graphs, where either efficiency or cost‐adjusted efficiency is plotted against a normalized measure of cost. The former curve resides in the unit square and is analogous to the receiver operating characteristic curve used for testing.     

THE CRAMÉR-RAO INEQUALITY

The essential significance of the Cram-Rao inequality is investigated. This inequality states a relation between the rate of change of a mean value and a rate of change of the probability measure. Simple, general regularity conditions are obtained.     

The evolution of human warfare

Here we propose a new theory for the origins and evolution of human warfare as a complex social phenomenon involving several behavioral traits, including aggression, risk taking, male bonding, ingroup altruism, outgroup xenophobia, dominance and subordination, and territoriality, all of which are encoded in the human genome. Among the family of great apes only chimpanzees and humans engage in war; consequently, warfare emerged in their immediate common ancestor that lived in patrilocal groups who fought one another for females. The reasons for warfare changed when the common ancestor females began to immigrate into the groups of their choice, and again, during the agricultural revolution.     

The planning of a department store

A town or village attracts people from its hinterland to purchase goods by virtue of the amount and variety of goods on offer. Similarly, a department store attracts customers away from cempetitors by means of displays, staff expertise, stock holdings and numerous other parameters. The store is generally free to manipulate these parameters subject to certain restrictions; the manipulation will have a direct affect on the ultimate profitability of the store. This paper describes some current research that is being carried out in conjunction with a department store group. The ultimate aim is to link the corporate planning of the group and each store to detailed socioeconomic data describing the population. Some aspects of the problem have been investigated in depth, some are currently being discussed and some have not been considered at all as yet. The latest position will be reported and hopefully some feedback will be engendered.     

WITHIN U.S. TRADE AND THE LONG SHADOW OF THE AMERICAN SECESSION

Using data from U.S. commodity flow survey, we show that the historical Union–Confederacy border lowers contemporaneous trade between U.S. states by about 13%. The finding is robust over econometric models, survey waves, or aggregation levels. Including contemporaneous controls, such as network or institutional variables, lowers the estimate only slightly. Historical variables, such as slavery, do not explain the effect. Adding U.S. states unaffected by the Civil War, we argue that the friction is not merely reflecting unmeasured North–South differences. Finally, the border effect is larger for differentiated than for homogeneous goods, stressing the potential role for cultural factors and trust. (JEL F15, N72, N92, Z10)
