Potential forensic application of closely linked autosomal STR haplotype in complex kinship testing

It has been noticed that the most commonly used commercial STR kits and mtDNA may not be able to solve some special kinship cases, such as alleged aunt, uncle, niece, nephew or half-siblings. Due to its unique hereditary pattern, the haplotype of genetic markers could be a solution of these questioned family relationships. In this study, we investigated the genetic features of an autosomal STR cluster by employing confirmed family samples. To evaluate the forensic practical value of autosomal STR haplotype, 5 closely linked STR loci, D1S2127-D1S2138-D1S3460-D1S1643-D1S518, which were arranged in about 2 cM region (from 186.29 cM to 188.02 cM; 1 cM represents 1% average recombination between two loci) on chromosome one, were selected to compose haplotype. Genotyping of 60 samples from 8 trios (father–mother–children), 8 duos (father or mother–children), and 4 three-generation pedigrees were performed using PAGE. Haplotypes were identified in the child by determining alleles for all 5 loci transmitted from each parent. Total 73 haplotypes were detected in all samples and 34 haplotypes were observed to be passed down as a whole and was corresponding with the inherited characteristics of haplotype. In all family members, 34 unrelated individuals contributed 65 haplotypes, of which 62 haplotypes appeared only once and the rest 3 haplotypes appeared twice. No recombination was observed in 4 three-generation pedigrees. In conclusion, the haplotype consisting of 5 closely linked autosomal STRs could pass down steadily as a whole. The family specificity of most haplotypes may provide a unique advantage in forensic complex kinship testing.     

Steven Chaffee and the Future of Political Communication Research

This article discusses four basic characteristics of Steven Chaffee's research: going beyond the "common research wisdom," careful explication of concepts, avoiding unsubstantiated charges against the media, and investigation of the social aspects of communication. The evolution of political socialization research is used as an example of how these characteristics have strengthened Chaffee's contribution to that area and to the larger field of political communication. It is argued that the future of this field would benefit from emulation of these characteristics. Continuing problems of political communication research are noted, and various emerging problems are discussed.     

<Emphasis Type="Italic">Familias con Voz</Emphasis>: Community Survey Results from an Intimate Partner Violence (IPV) Prevention Project with Migrant Workers

The Migrant Clinicians Network’s Familias con Voz (Families with a Voice) project aims to train migrant men and women to become intimate partner violence (IPV) peer educators in their communities. In preparation for implementing educational activities, a community survey was conducted with 298 participants in three Texas border counties. Verbal abuse, such as name calling, was the most frequent type of violence reported. Men perceived anger as a cause of partner violence significantly more than women. Only 22% of respondents reported knowing of a shelter they could turn to for help. Surprisingly, a majority of participants cited “seeking help from the police” when asked about ways to decrease partner violence. Survey results offer insight into developing effective intervention programs by capturing the intended audiences’ beliefs and attitudes. Additionally, survey results reveal possible strategies for how to tackle IPV in U.S.-Mexico border migrant farmworker communities.

The Incidence and Impact of Family Violence on Mental Health Among South Korean Women: Results of a National Survey

This representative national survey examined incidence of husband-to-wife violence in the past year, lifetime exposure to parental violence, and the relationships between victimization experiences of family violence and mental health among South Korean women (N = 1,079). The major findings were that incidence rate of husband-to-wife violence among Korean women was 29.5%, which was much higher than those of other nations, and that their experiences of physical violence by husbands in the last year and lifetime verbal abuse by parents had strong associations with the mental health of victims. The findings suggest that preventive intervention programs for male perpetrators as well as domestic violence victims with mental health problems and comprehensive interventions for Korean couples are urgently needed. In addition, parents should be educated about how to modify their children’s behavior without physical punishment or verbal abuse.

Effects of Perpetrator and Victim Gender on Negative Outcomes of Family Violence

Growing up in a violent home predisposes children to a host of behavioral and emotional difficulties. This study examined whether perpetrator and victim gender have an impact on depressive symptoms and aggressive behavior for victims of child physical abuse (CPA) and also with regard to witnessing interparental violence (IPV). This study also examined whether witnessing siblings being abused would elicit high levels of depressive symptoms and aggressive behavior. College students (n = 675) were assessed for both exposure to IPV and child physical abuse prior to age 18. Participants completed measures of depression and aggression. With regard to victims of CPA, participants victimized by both parents and those victimized by mothers only had significantly higher levels of aggression. For depressive symptoms, females having both parents as perpetrators or fathers only had significantly higher depressive symptoms. With regard to witnessing IPV, being abused by both parents was associated with endorsement of more aggression and depressive symptoms. With regard to witnessing sibling violence, the results were similar to those found for victims of CPA.
