A three-year follow-up of the performance of a class of state police academy graduates using the MMPI-2

Research has demonstrated the utility of the MMPI-2 in identifying good and poor performance, dissatisfaction, termination, low performance ratings, unsatisfactory and satisfactory criterion groups, problematic behavior, corruption, and aggression. There is much research to suggest that certain patterns of responding to this measure by officer applicants predict job performance behaviors that supervisors and police executives view unfavorably. This study illustrates the fact that variables which are likely to predict police performance are less obvious and more subtle. Discussion centers on repression and underlying hostility.

Characterization and differentiation of aluminum powders used in improvised explosive devices – Part 1: Proof of concept of the utility of particle micromorphometry

Aluminum (Al) powders are commonly used in improvised explosive devices as metallic fuels, a component of explosive mixtures. These powders can be obtained readily from industrial‐scale and consumer products, and produced using unsophisticated “kitchen chemistry” techniques. This research demonstrates the potential of automated particle micromorphometry for comparisons between known source and questioned Al powders recovered from IEDs, as well as for insight into the method of Al powder manufacture. Al powder samples were obtained from legitimate manufacturers, and 56 samples were produced “in‐house” from Al‐containing spray paints and ball‐milled Al foils. Transmitted light microscope images of Al powder particles were acquired using an automated stage with automated z‐focus; 17 size and shape parameters were measured for all particles. Approximately 37,000–2,500,000 particles/sample were analyzed using an open‐source statistical package with customized code. Dimensionality reduction was required for processing the large datasets: eight of the 17 measured variables were selected based on inspection of the correlation matrix. Data from four subsamples from each of the 56 samples produced using “in‐house” methods were analyzed using ANOVA to assess the within‐ and between‐sample variation. High within‐sample variation was noted; however, ANOVA and post‐hoc Tukey's honestly significant difference (HSD) tests demonstrated that the between‐sample variation was substantially larger than the within‐sample variation. Each sample could be differentiated from all other samples in the test set. Future experiments will focus on ways to reduce the within‐sample variation, and additional statistical and microanalytical methods to classify sources and confidently constrain the method of Al powder manufacture.     

Like Talking to a Brick Wall: Implications of Emotion Metaphors for Mediation Practice

In this article, the authors discuss the role of emotions in mediation with the goal of providing practical insights that can improve the mediation process. Their assumption is that emotion is ever-present, particularly in conflict, and that acknowledging and addressing underlying emotions facilitates conflict transformation during the mediation process.     

Cognitive-behavioral treatment of men who batter: The short-term effects of group therapy

A cognitive-behavioral approach for the treatment of wife abuse was evaluated using a pre-post design and multiple outcome measures. The treatment approach consisted of assertiveness training, relaxation training, and cognitive restructuring. Treatment also focused on increasing the client's acceptance of sex-role changes. Data were available on 92 men who completed 12 sessions of a skills group and eight sessions of a supplemental process group. There were significant changes in the desired direction in anger level, jealousy, depression, and attitudes about women's roles. These changes were maintained after adjusting scores for social desirability response bias. The importance of adjusting scores for response bias or obtaining spouse's reports of the man's behavior is discussed.     

A discriminant function analysis of deciduous teeth to determine sex

Studies of deciduous teeth have concluded that crown size differences in these teeth between males and females are not reliable sex discriminators, in contrast to such differences in permanent teeth. This study measured the mesiodistal and faciolingual crown diameters of all deciduous teeth, as well as those of the permanent first molars, of 162 children from the Burlington Orthodontic Growth Study, conducted earlier in Burlington, Ontario, Canada. All 40 deciduous tooth diameters (20 mesiolingual and 20 faciolingual) were significantly different between the sexes, as were the permanent tooth diameters. Using three to five measurements of deciduous teeth, discriminant analyses of several samplings of these children produced discriminant functions in which 76 to 90% of the holdout samples were correctly classified by sex. Combinations of deciduous and permanent measurements were used to classify 83 to 85% of the holdout samples correctly. When compared with published data on other sample populations, the Burlington group is the most dimorphic for deciduous teeth and is within the range of permanent tooth dimorphisms of other populations. The level of classification accuracy, when using discriminant analysis of the deciduous teeth, can approach the accuracy levels of analysis using the permanent teeth.     

Government Borrowing in Australia

This article examines the Australian experience with coordinatedgovernment borrowing from federation to the present day. Itreveals significant changes in the purposes for which the borrowingarrangements were originally designed and are now used. Largelyfor this reason, the outward form of the arrangements no longerresembles their actual operation, causing severe accountabilityproblems. Whatever the advantages of coordinated governmentborrowing for economic management in a federal system, the Australianexperience shows that it may have economic disadvantages aswell. The time has come, therefore, for the borrowing arrangementsto be rethought and revised.     

A world apart. Swedish and Australian gender equality policy

This article focuses on the process of gender-equality policy in Sweden and Australia, from 1960 to 1990. It is suggested that the comparative gender analysis must be more susceptible for civil rights issues. A second argument is that the in-depth achievements of the Swedish gender equality policy and the relative weaknesses in other respects are better understood if Swedish gender policy is analysed from an institutional perspective. Finally, the analysis provides an institutional explanation of why it is problematic to establish and maintain policies that do not build on the dominant political tradition of the welfare state in question.     

Under the Radar: Airborne Arms Trafficking Operations in Africa

Airborne illicit arms traffickers from the former Soviet space are resourceful and adaptable international criminals who have built complex air trafficking networks by successfully cultivating strategic connections in a number of geographically distant states. This paper examines the airborne arms trafficking operations of networks from former Soviet states which transfer weapons and ammunition to areas of conflict in Africa, embargoed African states, or those descending into conflict. As such, these arms traffickers brazenly circumvent international regulations by obscuring their air cargo operations and securing impunity through subornation, fraud, and exploitation of lax regulations. Importantly, they rely on strategic connections in former Soviet states for a steady supply of arms, on states such as UAE for relaxed oversight and free trade zones for transit, product warehousing, and laundering of proceeds, and on carefully-cultivated connections with “big men” and/or local fixers in African states for speedy delivery and payment.
