The effects of physical effort on police officers' perception and aggression in simulated shooting incidents

Abstract

In the present experiment the effects of physical effort on police officers' aggression and perception in simulates shooting incidents were investigated. Based upon Kahneman's (1973) variable-allocation capacity model it was hypothesized that physical effort will result in a decease in aggression towards aggressive offenders. Based upon Kahneman's model and Easterbrook's (1959) Cue-Utilization-Hypothesis it was further expected that this decrease in aggression will be caused by an incorrect judgement of the aggression of aggressive offenders (and not by an impaired perception). The findings confirmed these hypotheses.     

The Law Applicable to Divorce as Test Ground for Enhanced Cooperation

Enhanced cooperation was introduced in the Treaty of Amsterdam (1997). Despite a lot of academic ink being spilled, the instrument had, until recently, never been applied in practice. In June 2010, the Council reached consensus on authorising a group of Member States to pursue, in the framework of enhanced cooperation, common rules in the area of the law applicable to divorce. The present paper critically analyses this first precedent. For that purpose, the background to the policy area will be explored. Subsequently, the desirability of enhanced cooperation shall be assessed. Finally, the content of Rome III, and its effects upon Member States not participating in the initiative, will be analysed. The paper will attempt to formulate an answer to the question whether enhanced cooperation should be the new approach to harmonisation of family‐related Private International Law.     

Law, Morals and Defeasibility

This paper gives a logical characterization of the interrelation between law and morals. To this purpose it first outlines a logic for defeasible reasoning with rules and principles and illustrates the operation of this logic in the field of law. Then it offers a brief argument why law and morals are interrelated. This paper ends by showing how the logic for defeasible reasoning provides tools to logically characterize some aspects of the interrelation between law and morals.     

Recovery of Spray Paint Traces from Clothing by Beating

Manual recovery of spray paints from textiles using a microscope, the routine method in many laboratories, is often laborious. Beating the clothing with a plastic rod, the routine method used for recovery of glass traces within the authors’ laboratory, is proposed as an alternative. The efficiency of the method was evaluated by spray tests with fluorescent paint. In these tests, paint particles in the acquired debris samples, as well as those remaining on the textiles, were investigated. The results show that beating is an efficient way to recover and concentrate paint particles. A good efficiency for jeans fabric and rough knitwear is reported. The results appeared to be less satisfactory for smooth woven fabric. Application of the method in casework was effective for graffiti paints as well as for flaked car paint.     

Predictors of Group Performance in a Police Criminal Investigation Department: the Role of Gender Homogeneity,Leadership and Team Characteristics

The Netherlands’ Ministry of Security and Justice has agreed on performance targets with the country’s police departments. Introducing the targets created a shift to controlling performance in team management focus. This empirical study of police teams in Utrecht in the Netherlands (N = 134) focuses on the influence of leadership style, gender and psychosocial team factors when teams are required to achieve agreed performance objectives. We address calls in the literature for more research into (objective) measures relating to effective police leadership and existing (police) management practices. Gender homogeneity, a combination of charismatic, empowering and transactional leadership styles, and team members’ awareness of team achievements were found to be relevant. The practical implications of these results are discussed.
