When Initial Interviews Are Delayed a Year: Effect on Children's 2-Year Recall

Three- to nine-year-old children were interviewed about a medical emergency (injury requiring hospital ER treatment) two years after it occurred. Half of the number of children had been interviewed shortly after injury as well as 6 and 12 months later, while the remaining children had had only one prior interview a year after injury. There was remarkably little long-term deterioration in memory by both groups. Having a delayed initial interview had two effects, and both were relevant only to the harder-to-remember hospital treatment event: (a) The late-interview group was less accurate, and (b) early-interview children had more extensive free recall, suggesting that multiple prior interviews teach children the “rules of the memory game' when they are asked open-ended questions. Forensic implications are discussed.     

Measurement Properties of the Communities That Care<Superscript>®</Superscript> Youth Survey Across Demographic Groups

Prevention science has produced information about risk and protective factors that predict adolescent drug use and related problem behaviors. This paper investigates the Communities That Care Youth Survey that measures multiple risk and protective factors. Using a sample of 172,628 students who participated in surveys administered in seven states in 1998, analyses were conducted to test the factor structure of these risk and protective factors and to test the equivalence of the factor models across five racial/ethnic groups (African Americans, Asians or Pacific Islanders, Caucasians, Hispanic Americans, and Native Americans), four grade levels (6th, 8th, 10th, and 12th) and both gender groups. Results support the construct validity of the surveys risk and protective factor scales and indicate that the measures are equally reliable across males and females and five racial/ethnic groups. Implications of these findings for science-based prevention planning are discussed.     

The Effect of Religiosity on Endorsement of Democratic Values: The Mediating Influence of Authoritarianism

This study addresses the as yet unaddressed question of the nature of the effects of religiosity and authoritarianism upon endorsement of abstract democratic values. Findings obtained through the analyses of structural equations show that, despite the unsettled political and security atmosphere, Israelis believe in democratic values to a considerable extent. Furthermore, findings do not fully support the theoretical expectation that religiosity is likely to decrease support for democratic values; namely, in and of itself, religiosity has a negligible impact on endorsement of democratic values. Yet again, analyses lend credence to theory on authoritarianism—the negative effect of religiosity on endorsement of democratic values results from the mediation of authoritarianism. These findings are understood and discussed with regard to theoretical implications. The major conclusion, then, in contrast to existing assumptions regarding religiosity and negation of democracy linkage, is that religiosity cannot be considered the sole direct root cause of negation of democracy.     

Personality Pathways to Impulsive Behavior and Their Relations to Deviance: Results from Three Samples

The importance of the relation between impulsivity and deviance is well-acknowledged among criminologists. However, differences in the representations of impulsivity, some merely titular and others substantive, may cloud our understanding of these relations. The current study examines the argument, offered by Whiteside and Lynam Pers. Individuals Diff. (2000) 30: 669–689, that there may be four distinct personality pathways through which impulsive behavior may be manifested. Across three samples (two undergraduate, one community), we examine the validity of a four-factor structure of impulsivity, test whether these four pathways manifest divergent relations with various forms of deviant behavior such as crime and substance use, as well as laboratory manifestations of aggressive and impulsive behavior, and examine the invariance of these results across gender. The results support the existence of a four-factor model of impulsivity, the importance of two specific personality pathways in relation to self-reports of deviance (lack of premeditation and sensation seeking), as well as actual behavior, and suggest that these pathways are important for both men and women.     

Good cop—Bad cop: Problem officers,law enforcement culture,and strategies for success

Police officers are the only professionals mandated by society to use discretionary coercive physical force as a necessary component of fulfilling their duty to maintain public safety and uphold the law. If community policing is to prevail as an effective and credible style of law enforcement, the legitimate use of competent police authority will continue to be a vital issue. This article analyzes the types of officer problems and problem officers that can harm community policing efforts. These include (1) individual factors, such as attitudes, personality traits, and psychological disorders; (2) police-citizen interaction factors, such as interpersonal dynamics and community attitudes; and (3) organizational factors, such as training and supervision, departmental philosophy, and the “cop culture.” The article then offers practical strategies for improving officer performance, including (1) selection and screening of officers; (2) training and supervision; (3) fitnessfor-duty evaluations; (4) effective supervision and discipline; (5) coaching and counseling strategies; and (6) the most productive use of psychological services. Throughout this discussion, the concept of the police officer as a law enforcement professional is emphasized as essential for guiding public safety policy into the 21^st century.     

Linking arson incidents on the basis of crime scene behavior

The present study investigated the possibility of statistically linking arson cases based on consistency of behaviors from one crime scente to another. Serial and spree arson cases were studied to differentiate underlying themes and to link cases committed by the same offender. The material consisted of 248 arson cases which formed 42 series of arsons. A content analysis using 45 dichotomous variables was carried out and principal compnents (PCA) analysis was performed to identify underlying themes. Summary scores reflecting the themes were calculated. Linking effectiveness was tested with a discriminant analysis using the summary scores. The PCA analysis was successful and underlying themes which were in accordance with previous studies could be identified. Six factors were retained, in the PCA. The linking of the arson cases was possible to a satisfactory level: 33% of the cases could be correctly linked and for over 50% of the cases, the series they actually belonged to was among the ten series identified as most probable on the basis of the linking analysis. From a practical point of view, the results could be used as a basis for developing support systems for police investigations of arson. This research was financially supported by the Finnish Ministry of Interior and by Grant 54456 from the Academy of Finland.     

A re-examination of the MMPI-2 aggressiveness and immaturity indices in law enforcement screening

This study reports an analysis of Bartol's (1991) Immaturity Index and Hargrave and associates' (1988) Aggressiveness Index as a measure of police conduct. The correlations between the supervisory ratings and the Immaturity and Aggressiveness indices were examined for 1020 law enforcement officers. The results showed that Immaturity Index was related to termination for failure to complete training and insubordination. The Aggressiveness Index was related to a termination for failure to complete training and several other problematic police behaviors, but was not found to be specifically linked with acts of aggression. Implications for using these two indices in law enforcement selection are discussed.

STR analysis of artificially degraded DNA-results of a collaborative European exercise

Degradation of human DNA extracted from forensic stains is, in most cases, the result of a natural process due to the exposure of the stain samples to the environment. Experiences with degraded DNA from casework samples show that every sample may exhibit different properties in this respect, and that it is difficult to systematically assess the performance of routinely used typing systems for the analysis of degraded DNA samples. Using a batch of artificially degraded DNA with an average fragment size of approx. 200 bp a collaborative exercise was carried out among 38 forensic laboratories from 17 European countries. The results were assessed according to correct allele detection, peak height and balance as well as the occurrence of artefacts. A number of common problems were identified based on these results such as strong peak imbalance in heterozygous genotypes for the larger short tandem repeat (STR) fragments after increased PCR cycle numbers, artefact signals and allelic drop-out. Based on the observations, strategies are discussed to overcome these problems. The strategies include careful balancing of the amount of template DNA and the PCR cycle numbers, the reaction volume and the amount of Taq polymerase. Furthermore, a careful evaluation of the results of the fragment analysis and of automated allele calling is necessary to identify the correct alleles and avoid artefacts.
