Area characteristics and regional variates as determinants of area property crime levels

This article seeks to examine the area characteristics that act as determinants of area property crime levels, namely, incidence and prevalence. The crime figures are extracted from the 1984 British Crime Survey. Area characteristics are taken from the 1981 UK census. Initial exploratory analysis considers the non-Gaussian nature of the crime data, the statistical implications of this, and the transformations used to overcome these problems. In addition, possible regional and inner-city/non-inner-city variations are considered. The later stages move from simple individual correlations to multiple regression models. Three regression models are considered and the reasons for refining these are explored, with the results indicating that both area characteristics and regional influences play a role as determinants of the area crime level. In particular, population density and the area population age profile have significant roles to play. The conclusions support the recent revival of the application of ecological concepts in the analysis of crime levels.     

Characteristics of Callers to the Domestic Abuse Helpline for Men

Intimate partner violence (IPV) by women against men has been the subject of much debate. Feminists typically argue that IPV is committed only by men against women. Others argue that violence is a human problem and women also commit much IPV. To resolve these debates, IPV has been classified into two categories: common couple violence captured by population-based studies, and patriarchal terrorism, captured by studies of battered women. This typology ignores male victims of extreme IPV. The current study addresses this omission by describing 190 male callers to the Domestic Abuse Helpline for Men. All callers experienced physical abuse from their female partners, and a substantial minority feared their wives’ violence and were stalked. Over 90% experienced controlling behaviors, and several men reported frustrating experiences with the domestic violence system. Callers’ reports indicated that their female abusers had a history of trauma, alcohol/drug problems, mental illness, and homicidal and suicidal ideations.

Differences in the Validity of Self-Reported Drug Use Across Five Factors: Gender,Race, Age,Type of Drug,and Offense Seriousness

This study expands our knowledge about the validity of self-reported drug use by examining how gender, race, age, type of drug, and offense seriousness interact to affect the validity of self-reported drug use. This study also provides a conceptual framework that can be used to examine the validity of self-reported drug use. Differences in the validity of self-reported drug use are explained by examining differences in underreporting and overreporting. Differences in underreporting and overreporting are then further examined while controlling for differences in base rates of drug use. As shown, whether one controls for base rates of use may drastically affect estimates of underreporting and overreporting. By using hierarchical loglinear, logit, and logistic regression models with the Drug Use Forecasting data, we show that Black offenders provide less accurate self-reports than White offenders. Black offenders do so because they are more likely to underreport crack/cocaine use than White offenders. This difference, however, disappears once differences in base rates are controlled. A Black offender who tests positive is not more likely to underreport crack/cocaine use than a White offender who tests positive. Black offenders are also more likely to overreport both marijuana and crack/cocaine use relative to White offenders. Contrary to the first, this difference is not attributable to a difference in base rates. Methodological and substantive implications of this distinction are discussed. No differences across gender, age, or offense seriousness were found.

A comparative analysis of media reports of U.S. parricide cases with officially reported national crime data and the psychiatric and psychological literature

This article is a content analysis of 150 unique cases of children killing parents in the United States as reported in the electronic news media. The accuracy of online coverage of U.S. parricide incidents is assessed using two types of resources: officially reported national statistics on known parricidal incidents and the psychological and psychiatric literature on matricide and patricide. Comparisons of news accounts of media-reported U.S. parricide cases with Supplementary Homicide Report data indicate that electronic media coverage of parricide cases focused on the more sensational and unusual parricides. Analyses of these media accounts by offender age found 13 significant differences between juvenile and adult offenders. Ten of these 13 differences related to motive and Heide's parricide offender types (severely abused, severely mentally ill, and dangerously antisocial) and were consistent with the mental health-related literature in this area. The limitations and directions for future research are discussed at length.     

The EDNAP mitochondrial DNA population database (EMPOP) collaborative exercises: organisation, results and perspectives

This paper presents an overview of the organisation and the results of the collaborative exercises (CE) of the European DNA Profiling (EDNAP) Group's mitochondrial DNA population database project (EMPOP). The aim of the collaborative exercises was to determine whether uniformity of mtDNA sequencing results could be achieved among different laboratories. These were asked to sequence either the complete mtDNA control region or the two hypervariable regions HVI (16024-16365) and HVII (73-340) from DNA extracts, buccal swabs or bloodstains, proceeding in accordance with the protocol and strategies used in each individual laboratory. The results of the collaborative exercises were employed to identify possible sources of errors that could arise during the analysis and interpretation of mtDNA profiles. These findings were taken as a basis to tentatively make suitable arrangements for the construction of a high quality mtDNA database. One hundred fifty mtDNA profiles were submitted to the evaluating laboratory, and disaccording profiles were classified into four groups corresponding to the source of error: clerical errors, sample mix-ups, contaminations and discrepancies with respect to the mtDNA nomenclature. Overall, 14 disaccording haplotypes (16 individual errors) were observed. The errors included 10 clerical errors, 3 interpretation problems, 2 cases of sample mix-up and 1 case of point heteroplasmic mixture, where the 2 sequencing reactions brought inconsistent base calls. This corresponds to an error rate of 10.7% in a virtual mtDNA database consisting of the collaborative exercise results. However, this estimate is still conservative compared to conclusions drawn by authors of meanwhile numerous publications critically reviewing published mtDNA population databases. Our results and earlier published concerns strongly emphasize the need for appropriate safety regulations when mtDNA profiles are compiled for database purposes in order to accomplish the high standard required for mtDNA databases that are used in the forensic context.
