Testing and evaluation of 43 "noncore" Y chromosome markers for forensic casework applications

A developmental validation study was performed on three Y-STR multiplex systems, Multiplex III (MPIII), Multiplex IV (MPIV), and Multiplex V (MPV), to ascertain their potential applicability to forensic casework. MPIII contains eight Y-STRs, including DYS426, DYS435, DYS436, DYS441, DYS442, DYS446, DYS462, and Y-GATA-A10, and one InDel, YAP (DYS287). MPIV contains 21 Y-STR loci, including DYS443, DYS444, DYS445, DYS447, DYS448, DYS449, DYS452, DYS453, DYS454, DYS455, DYS456, DYS458, DYS463, DYS464, DYS468, DYS484, DYS522, DYS527, DYS531 DYS557, and DYS588. MPV contains 13 Y-STR loci, including DYS459, DYS476, DYS488, DYS513, DYS549, DYS561, DYS570, DYS575, DYS576, DYS590, DYS594, DYS598, and DYS607. Full genetic profiles were consistently obtained for all three multiplexes with 25-50 pg of male DNA. No significant amplification was observed with 1 mug of female DNA. Each multiplex permitted the determination of the number of male donors in male:male DNA admixtures. Species specificity studies demonstrated some cross-reactivity with some primate samples. Environmentally compromised blood samples produced full or partial profiles after exposure to various conditions for up to 1 year. Full profiles were recovered from simulated casework specimens including cigarette butts and postcoital cervicovaginal swabs. Population data were collected to determine individual loci gene diversity and multiplex discriminatory capacity.     

Inference of human geographic origins using Alu insertion polymorphisms

The inference of an individual's geographic ancestry or origin can be critical in narrowing the field of potential suspects in a criminal investigation. Most current technologies rely on single nucleotide polymorphism (SNP) genotypes to accomplish this task. However, SNPs can introduce homoplasy into an analysis since they can be identical-by-state. We introduce the use of insertion polymorphisms based on short interspersed elements (SINEs) as a potential alternative to SNPs. SINE polymorphisms are identical-by-descent, essentially homoplasy-free, and inexpensive to genotype using a variety of approaches. Herein, we present results of a blind study using 100 Alu insertion polymorphisms to infer the geographic ancestry of 18 unknown individuals from a variety of geographic locations. Using a Structure analysis of the Alu insertion polymorphism-based genotypes, we were able to correctly infer the geographic affiliation of all 18 unknown human individuals with high levels of confidence. This technique to infer the geographic affiliation of unknown human DNA samples will be a useful tool in forensic genomics.

EFFECTS OF SKILL-BASED VERSUS INFORMATION-BASED DIVORCE EDUCATION PROGRAMS ON DOMESTIC VIOLENCE AND PARENTAL COMMUNICATION

This study used a pre- and postevaluation with a control group to compare the effectiveness of two divorce education programs: skill-based Children in the Middle (CIM) and informationbased Children First in Divorce (CFD). Each treatment group consisted of approximately 125 divorcing parents mandated to attend divorce education in Florida. The control group consisted of 64 divorcing parents not mandated to attend divorce education in Alabama for lack of a program. Treatment and control parents lived in comparable cities with comparable demographics. Results indicate that CIM, not CFD, improved parental communication. Both CIM and CFD reduced child exposure to parental conflict. Neither program had effects on domestic violence, actual parental conflict, or child behavior problems. Across all groups, parents with greater divorce knowledge and communication skills experienced more reciprocal discussions with the other parent, less parental conflict, less domestic violence, and they exposed children to less conflict.     

A FRAMEWORK FOR THE ANALYSIS OF SOCIAL REGULATION

The emphasis of this paper is on the development of a framework for analyzing the impacts of governmerit intervention on issues of public health and safety. Government policies are classified into three general strategies: regulatory, fiscal, and educational. In most issues, governments pursue policies in all three categories. The authors explain how the effects not only of specific policies, but also of these general policy types can be assessed over the range of social issues. The conceptual framework is tested with regard to a particular issue–alcohol-related traffic accidents–across the American states from 1979-1 984. The results suggest that fiscal and educational policies had little effect, but certain of the regulatory policies tended to be related to traffic fatalities involving alco- hol. The empirical analysis demonstrates the utility of the conceptual framework presented.
