Population data at two short tandem repeat loci D2S1338 and D19S433 in the sample of multinational Bosnia and Herzegovina residents

POPULATION: We have analyzed the distribution of allele frequencies at two short tandem repeats loci (D2S1338 and D19S433) in a multinational sample of Bosnia and Herzegovina (B&H) residents. A total of 110 unrelated male and female individuals (Caucasians) from different regions of B&H were sampled for the analysis. We ensured that the sample reflected approximate proportional participation of the three main ethnic groups in the population of B&H (Bosniacs-Muslim [45%], Serbs [34%], Croats [21%]).

Reassessing the Cross-National Relationship Between Income Inequality and Homicide Rates: Implications of Data Quality Control in the Measurement of Income Distribution

A significant positive relationship between income inequality and homicide rates has been found in a large number of cross-sectional studies and a few longitudinal analyses; a theoretically interesting interaction effect between income inequality and social welfare has also been found. For the most part researchers have been willing to use generous quality criteria in collecting income-distribution data, to maximize sample size and thereby enhance statistical power and representativeness. In the present paper we use a recently developed data set with explicit quality ratings for the income-distribution data, which permits systematic assessment of the consequences of relying on income-distribution measures of varying quality in examining the inequality-homicide relationship. Our analyses reveal that the income inequality-homicide relationship is remarkably robust in cross-sectional analyses. Regardless of the quality of income-distribution data, we observe significant positive effects of the Gini coefficient on homicide rates in cross-sectional multivariate models. Consistent results are also observed when an interaction term for income inequality and decommodification is examined. The results of longitudinal analyses differ; we observe a significant positive effect of changes in inequality on changes in homicide rates only when income-distribution measures of low quality are used.

Normal responses to sexually anatomically detailed dolls

The behaviors and verbalizations of normal, preschool age boys and girls during interactions with sexually anatomically detailed (SAD) dolls were examined. A structured, nonsuggestive interview with each child was videotaped, and five behaviors and five verbalizations were coded for each of five phases of the interview. A two-way ANOVA (gender × phase) showed that during those phases when the dolls were undressed, both boys and girls showed more sexual exploratory play, aggressive behavior which was nonsexual, and active avoidance. Across all phases, nonsexual aggression accounted for 31% of the boys' and 22% of the girls' total responses. Behavioral and verbal sexual exploratory play represented 42% of the boys' responses and 50% of the girls' responses. In contrast, sexually aggressive behavior accounted for only 1% and 2% of the boys' and girls' responses, respectively. Girls interacted with the dolls more than did boys. Additionally, girls demonstrated more affection to the dolls than did the boys, and boys displayed more anxiety with the dolls than did girls. Investigators should be cautious as to inferences about preschoolers' interactions with SAD dolls, especially interactions of a sexual or aggressive nature which do not clearly depict fondling or intercourse.     

Victim's perceptions of initial police responses to robbery and aggravated assault: Does race matter?

Despite the fact that police officers are usually the first persons within the criminal justice system to respond to a criminal victimization, the majority of research investigating racial discrimination within the system has examined primarily the effects of race on adjudication outcomes which occur after initial police interventions, such as conviction decisions and sentences. Very little empirical effort has been devoted to examining the effects of race on early police responses to a reported victimization. Using data from the National Crime Victimization Survey from 1987 to 1992, this paper investigates the effects of both the victim's and the offender's race on three police responses to robbery and aggravated assault: (1) police response time to the scene, (2) effort exerted by the police at the scene, and (3) likelihood of arrest. It was found that police were quicker to respond and also exerted more effort at the scene such as searching and taking evidence to incidents of black on white robbery compared to all other racial dyads. This relationship held even after controlling for other factors such as victim-offender relationship, poverty, injury to the victim, and victim's gender. No significant effects of race, however, were found when predicting the probability of arrest in cases of robbery. The effects of race on police responses to aggravated assault were more complicated. For assaults involving strangers, police were significantly more likely to exert additional effort at the scene if the victim was white and the offender was perceived to be black. This effect was reversed, however, for nonstranger assault victimizations. Police were significantlyless likely to exert effort at the scene or to make an arrest in black on white assaults involving nonstrangers. The most consistent predictors of arrest in both stranger and nonstranger assault victimizations were police response time, injury to the victim, and the incident occurring in a public setting.
