Priming Unconscious Racial Stereotypes About Adolescent Offenders

Two studies examined unconscious racial stereotypes of decision makers in the juvenile justice system. Police officers (Experiment 1) and juvenile probation officers (Experiment 2) were subliminally exposed to words related to the category Black or to words neutral with respect to race. In a presumably unrelated task, officers read 2 vignettes about a hypothetical adolescent who allegedly committed either a property crime (shoplifting from a convenience store) or an interpersonal crime (assaulting a peer). The race of the offender was left unstated and the scenarios were ambiguous about the causes of the crime. Respondents rated the hypothetical offender on a number of traits (e.g., hostility and immaturity) and made judgments about culpability, expected recidivism, and deserved punishment. They also completed a self-report measure of conscious attitudes about race. As hypothesized, officers in the racial prime condition reported more negative trait ratings, greater culpability, and expected recidivism, and they endorsed harsher punishment than did officers in the neutral condition. The effects of the racial primes were not moderated by consciously held attitudes about African Americans. The implications of the findings for racial disparity in the juvenile justice system and for changing unconscious stereotypes were discussed.     

Forensic ethnic identification of crania: the role of the maxillary sinus--a new approach

Forensic pathologists may be asked to identify the ethnic group and gender of a cranium of unknown origin. An analysis of the maxillary sinus--its volume, shape, and dimensions in dried crania of different ethnic and gender groups (European and Zulu male and female)--was conducted to establish a new approach. A variation in maxillary sinus volume may mean a variation in anatomic landmarks between the groups. Ethnic and gender variations in the shape of the maxillary sinus of the crania were investigated. This research was further extended to predict the gender and ethnic group from an unknown cranium to make this research valuable to the fields of forensic pathology and anthropology. Helical, multislice computed tomography was performed using 1-mm coronal slices. The area for each slice was obtained by tracing the outline of each slice. The computed tomographic machine calculated a volume by totalling the slices for each sinus. Advanced computer methodology including a neural network was designed and applied to search for classification patterns in data. A discriminant analysis was performed to improve classification results. Ethnic and gender variations were found in the different groups, and the predictive role of the maxillary sinus in ethnic classification was established. It was found that European crania had significantly larger antral volumes than Zulu crania, and males had larger volumes than females. Dimensions of European sinuses were larger than those of Zulu sinuses. The medial antral wall of the sinus allowed for ethnic classification. The discriminant analysis allowed for a very successful 90% ethnic prediction, while gender prediction was ultimately 79%. The measurements taken and the formulae created in this research will be valuable to those in the field who are seeking to ethnically classify a cranium into one or another ethic group. This research aims to be an aid in identification, as well as a starting point for other scientific studies based on other ethnic groups. Perhaps its true value will lie in confirming ethnicity by adding to existing criteria. It must be noted that this classification is based on actual measurements and therefore eliminates the some of the subjectivity present in current methods of ethnic classification.     

Exploring the forensic use of the emotional recognition test (ERT)

General "hypo-emotionality" has now become a broadly accepted concept as one of the conspicuous psychological characteristics of repetitive, violent offenders. Numerous psychophysiological studies have verified this premise. The current study sought to examine the applicability of the Emotional Recognition Test (ERT) in a sample of 85 Korean inmates in a maximum-security prison. Two additional criterion groups were included for comparison: normal controls and schizophrenic inpatients. Because the ERT consists of problem-solving items, it is relatively free from response biases and is more efficient than measuring physiological responses. Results indicated that all criterion groups scored significantly differently on the ERT total and subscale scores. Additionally, similar to the physiological emotion-specific findings, emotion-specific subscales of the ERT indicated that offenders had significantly more difficulty in recognizing negative emotional stimuli, particularly sadness.     

Allele frequencies and genetic data of 16 highly polymorphic loci in Koreans

Allele and genotype frequencies for the 15 STR loci (FGA, vWA, MBP-L, MBP-H, HumTh01, D3S1358, D3S2406, D5S818, D7S820, D8S1179, D13S317, D18S51, D19S253, and D21S11) and two VNTR loci (D1S80 and D17S5) in a sample of unrelated Koreans were determined.     

Analysis of the CODIS autosomal STR loci in four main Colombian regions

Genotype polymorphism studies at the 13 loci STRs included in the combined DNA index system [CODIS and PCR-based short tandem repeat loci, in: Proceedings of the Second European Symposium on Human Identification, Promega Corporation, Madison, WI, 1998, pp. 73-88; J. Forensic Sci. 46 (2001) 453] (CODIS: D3S1358, HUMvWA31, HUMFGA, D8S1179 D21S11, D18S51, D5S818, D13S317, D7S820, HUMTH01, HUMTPOX, HUMCSF1PO and D16S539) were carried out in a sample of 1429 unrelated Colombian individuals belonging to 25 different departments. As many other countries in Latino-America, Colombia shows an important admixture component, basically integrated by Amerindians, European-descendants and African-descendants. Due to the fact that only partial population analyses have been carried out in the country, the main aim of the present analysis is to establish a database of forensic interest based on the widely used CODIS systems covering the main Colombian regions.     

The poor in Singapore: issues and options

This article examines the changing patterns of poverty in Singapore. As Singapore's population ages, the poor increasingly includes the elderly. It appears that ascribed factors, such as gender and race, have significant influence on financial security at old age. As the population ages, the adequacy of existing anti-poverty policy is challenged.
