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.     

Genetic variability of 16 Y-chromosome STRs in a sample from Equatorial Guinea (Central Africa)

Nine Y-STR loci from the "minimal haplotype" included in Y-STR Haplotype Reference Databases (YHRD) together with eight additional Y-STRs (DYS437, DYS438, DYS439, DYS460, DYS461, GATA C4, GATA H4 and GATA A10) were analyzed in a sample of 101 males from Equatorial Guinea living in Madrid. Haplotype and allelic frequencies were calculated and genetic diversities were estimated for each genetic system as well as for the whole haplotype. An unexpected high frequency (6%) of intermediate alleles (13.2 and 14.2) was found in DYS385. For DYS19, two alleles were found in one sample. Another sample failed to amplify with DYS393 primers using either PowerPlex Y System (Promega Corporation) or the Y-PLEXtrade mark 12 (Reliagene, New Orleans, LA) commercial kits. Comparison between Equatorial Guinea and another African population (Mozambique; South East Coast) revealed a significant pairwise Phi(st) value between them (Phi(st)=0.03309; P=0.00000).     

Y-chromosomal STR haplotypes in three ethnic groups and one cosmopolitan population from Tunisia

The 11 Y-chromosomal short tandem repeats (STRs) included in the Promega Corporation PowerPlex Y System (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438 and DYS439) were typed in three ethnic groups ("Andalusians", Berber and Arab) and one cosmopolitan population (Tunis) from Tunisia, summing up 247 individuals, and 139 different haplotypes. Focusing the analysis on the seven Y-STRs of the YHRD Minimal Haplotype Core (DYS385 excepted), "Andalusians" showed no differences from the Cosmopolitan and the Arab samples previously published (our Arab sample presented an extremely low haplotype diversity), but were different from the Berbers. The Berbers from Tunisia were not different from those from Morocco.     

Mitochondrial DNA error prophylaxis: assessing the causes of errors in the GEP'02-03 proficiency testing trial

A qualitative and quantitative analytical method was developed and validated for the determination of 49 licit and illicit drugs in oral fluid. Small oral fluid samples, volume 1mL, were collected from volunteers using a modified Omni-Sal device and the analytes were extracted from an oral fluid/buffer mixture using a single Bond Elut Certify solid phase extraction cartridge. Liquid chromatography-tandem mass spectrometry (LC-MS-MS) and gas chromatography-repetitive full scan mass spectrometry (GC-MS) were used in parallel to analyze the extracts for the targeted drugs. Extracts were analyzed by GC-MS in their underivatized form and as their pentafluoropropionyl derivatives. Deuterated internal standards were used for quantification of drugs of abuse by LC-MS-MS to minimize matrix effects. Methadone-d(9) and tumoxetine were used as the internal standards for quantification of non-derivatized and derivatized analytes respectively by GC-MS. Linearity was demonstrated over the range 5-200 ng/mL and limits of detection were less than 4 ng/mL for each drug analyzed. The method demonstrated acceptable recoveries for most of the analytes and good intra- and inter-day precision. Acquisition of data by repetitive full scan GC-MS allows the addition of further analytes to the target menu.     

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.
