The Personal Fable and Risk-Taking in Early Adolescence

Elkind’s (1967) theory of adolescent egocentrism proposes two distinct, but related, constructs – the imaginary audience and the personal fable. A corollary to the imaginary audience, the personal fable (PF) yields a sense of invulnerability and speciality commonly associated with behavioral risk-taking. When regarded as a developmental phenomenon, risk-taking is thought to be the result of cognitive immaturity. However, few adolescent health programs address the egocentric dimension of decision making. We believe that a valid and reliable measure of PF would aid assessment of risk-taking potential and inform preventive interventions. The present paper reports the results of a newly constructed measure of PF and its relation to risk-taking behavior. The following three hypotheses were tested using data from an availability sample of 119 middle school students: 1. PF scores will increase with age; 2. males will score higher than females on the invulnerability dimension of PF; and 3. PF and risk-taking will be positively correlated. As predicted, PF scores increased significantly across the age range studied. Of the two PF dimensions, only invulnerability significantly varied across grades. Males reported significantly higher invulnerability scores than females, and PF and risk-taking were positively correlated. Suggestions for the implementation of this new and, arguably, reliable and valid scale are presented. Amy Alberts, M.

Speedy trial and the legal process

The role of speedy trial in state proceedings is empirically investigated for defendants in criminal homicide (N=444). Employing multiple regression techniques, an assessment is made of the relationship between the length of time involved in defendants' legal processing, their sociolegal status, and the final dispositions awarded by the court. The findings show that blacks and jailed defendants are processed more swiftly than their white and bailed counterparts. The consitutional guarantee of speedy trial also appears to be a state resource, in that cases adjudicated promptly result in higher conviction rates than those which are delayed. This is especially so for defendants who are not released on bail, and may be attributed to the prosecutorial success that accompanies the availability of witnesses whose memories are unclouded by time and the existence of a social climate that calls for retribution. While not related to postponement in the present study, it is suggested that the efforts of counsel in obtaining delay may become increasingly important with the adoption of the new federal guidelines.     

Allele frequencies for 70 autosomal SNP loci with U.S. Caucasian, African-American, and Hispanic samples

189 samples from 3 different U.S. sample groups Caucasian (74), African American (71) and Hispanic (44) were typed for 70 autosomal genetic markers. These 70 markers are bi-allelic (C/T) short nucleotide polymorphisms (SNPs). For each sample, the 70 SNP markers were typed in 11 unique 6-plexes and a single 4-plex PCR. A total of 10 of the 210 tests (70 loci x 3 populations) for Hardy-Weinberg equilibrium indicated a statistically significant result. In order to evaluate the minimum number of SNP loci needed to distinguish all 189 samples from one another, we ranked the loci according to their levels of observed heterozygosity and p-values obtained upon testing for Hardy-Weinberg equilibrium. The top 12 loci according to these ranking criteria were tabulated along with the number of unique genotypes observed when combining subsequent SNP markers. The 12 selected SNPs possessed an observed heterozygosity of >0.45 in all three populations examined and thus would be expected to exhibit more differences between samples. All of the 189 samples in this study were individualized with a subset of 12 SNP loci. However, it is likely that the addition of more than 12 SNP loci will be required to resolve larger sets of unrelated individuals from one another. By way of comparison, in these same 189 individuals all but one pair is resolved from one another with three of the traditional short tandem repeat (STR) loci possessing the highest heterozygosity values (D2S1338, D18S51, and FGA) run with the Identifiler kit. The final pair of unrelated samples could be resolved with the combination of 4 STR loci: D2S1338, D18S51, FGA, and VWA.     

Gender/Racial Differences in Jock Identity,Dating, and Adolescent Sexual Risk

Despite recent declines in overall sexual activity, sexual risk-taking remains a substantial danger to US youth. Existing research points to athletic participation as a promising venue for reducing these risks. Linear regressions and multiple analyses of covariance were performed on a longitudinal sample of nearly 600 Western New York adolescents in order to examine gender- and race-specific relationships between jock identity and adolescent sexual risk-taking, including age of sexual onset, past-year and lifetime frequency of sexual intercourse, and number of sexual partners. After controlling for age, race, socioeconomic status, and family cohesion, male jocks reported more frequent dating than nonjocks but female jocks did not. For both genders, athletic activity was associated with lower levels of sexual risk-taking; however, jock identity was associated with higher levels of sexual risk-taking, particularly among African American adolescents. Future research should distinguish between subjective and objective dimensions of athletic involvement as factors in adolescent sexual risk.Research Scientist at the Research Institute on Addictions of the University at Buffalo.

A forensic laboratory tests the Berkeley microfabricated capillary array electrophoresis device

Miniaturization of capillary electrophoresis onto a microchip for forensic short tandem repeat analysis is the initial step in the process of producing a fully integrated and automated analysis system. A prototype of the Berkeley microfabricated capillary array electrophoresis device was installed at the Virginia Department of Forensic Science for testing. Instrument performance was verified by PowerPlex 16 System profiling of single source, sensitivity series, mixture, and casework samples. Mock sexual assault samples were successfully analyzed using the PowerPlex Y System. Resolution was assessed using the TH01, CSF1PO, TPOX, and Amelogenin loci and demonstrated to be comparable with commercial systems along with the instrument precision. Successful replacement of the Hjerten capillary coating method with a dynamic coating polymer was performed. The accurate and rapid typing of forensic samples demonstrates the successful technology transfer of this device into a practitioner laboratory and its potential for advancing high-throughput forensic typing.     

An unusual case of child head injury by coat hanger*

Traumatic brain injury is the leading cause of morbidity and mortality among children suspected of child abuse. Penetrating cranio-facial injuries are generally rare in the pediatric age group and are caused by both accidental and inflicted mechanisms. We report an unusual case of a 2-year-old female who was admitted to a pediatric emergency room with an industrial stainless steel coat hanger impaled in her skull. Pertinent clinical forensic medicine examination, coupled with home inspection and interviews by the local law enforcement, revealed a horrible episode of domestic violence.
