This study demonstrates that the locus D1S80 is highly polymorphic in the Bahrainian population. There were 24 different D1S80 alleles and 51 distinct genotypes observed in 198 Bahrainians. There was one allele observed that was smaller than the 14 repeat allele. This data set meets the Hardy-Weinberg expectations (HWE) and could be a useful marker for parentage testing and forensic applications.  相似文献

Prostate specific antigen (PSA, also known as p30), a glycoprotein produced by the prostatic gland and secreted into seminal plasma, is a marker used for demonstrating the presence of seminal fluid. Methods for the detection of PSA include Ouchterlony double diffusion, crossover electrophoresis, rocket immuno-electrophoresis, radial immunodiffusion, and ELISA. The extremely sensitive ELISA technique can detect PSA in concentrations as low as approximately 4 ng/mL. However, all these techniques are cumbersome and time consuming to perform in forensic laboratories, especially when only a few samples per week are processed. Various membrane tests are currently used in clinical settings to screen a patient's serum for the presence of PSA at levels greater than 4 ng/mL. In this study we evaluated three immunochromatographic PSA membrane tests by analyzing semen stains stored at room temperature for up to 30 years, post-coital vaginal swabs taken at different time after intercourse, semen-free vaginal swabs, and various female and male body fluids, including urine. The data demonstrate that PSA membrane test assays offer the same sensitivity as ELISA-based tests and provide a rapid approach for the forensic identification of seminal fluid. Furthermore, when the supernatant from a DNA extraction is used for the assay, there is essentially no DNA consumption for determining the presence of PSA in a forensic sample.  相似文献

Adolescence is perhaps the most difficult period of child rearing for parents. This study attempted to identify disciplinary techniques used by parents as perceived by mothers, fathers, and their adolescent children. Results indicated several significant areas of intrafamilial disagreement in regard to disciplinary techniques utilized, although all subjects tended to agree that some form of verbal reasoning was the primary disciplinary technique utilized with these adolescents.This study was funded, in part, by the Ohio Agricultural Research and Development Center (H-644) and the School of Home Economics, The University of Georgia.Received his Ph.D. in child and family studies from the University of Tennessee.

Current contradictions in adolescent theory   总被引:1,自引:0,他引:1  
This article points out two contradictions in current adolescent theory. The first is between the classical point of view, espousing the notion of storm and stress, and the empirical view, supporting a concept of adolescence as relatively peaceful and harmonious. The latter approach, however, creates a second contradiction because it does not explain how young people cope with the major adaptations demanded as a result of changes in their physical, social, and emotional spheres of life. The article examines the status of concepts such as the generation gap and identity crisis and concludes with the formulation of a focal theory of adolescence which attempts to resolve the contradictions discussed earlier.Received his B.A. from McGill University, Montreal, and Ph.D. from University College, London.

This article is based on findings from semi-structured interviews and discussions among "chilimba" groups in Zambia. Chilimba groups are primarily women's groups that engage in credit and savings programs. Group membership ranges from 4 to 20 members. The women agree on a fixed, regular cash contribution that is given in turn to each member in a specified order. Market groups tend to be larger and contributions of about a dollar are made daily. Smaller groups tend to make larger, but less frequent contributions. Default is rare, as the commitment is taken very seriously. New members are added at the end of the rotation. Loans can be used for domestic or business use. Chilimba groups are evidence that very poor people desire savings. Chilimba brings together people with similar financial needs and resources. Chilimba does not require formal, written procedures or formal institutional frameworks. Chilimba is not a remedy for reducing overall poverty. It is appropriate only for people with some regular source of income. It does not serve as a safety net in emergencies. Long-term loans are not possible. A limitation is its openness and lack of structure that permit potential abuse. It is a livelihood strategy for women, but benefits could be gained from including men. It is urged that groups consider whether the position of the poor is being enhanced or undermined. Different models need to be tested. Members themselves must decide on the type and phasing of activities.  相似文献

Research Summary

For several decades, critics have argued that civil forfeiture laws create incentives for law enforcement to increase departmental revenue by “policing for profit.” By using data on federal equitable sharing payments to nearly 600 local law enforcement agencies between 2000 and 2012, we examine the relationship between the characteristics of state forfeiture laws and equitable sharing payments to local agencies. Our results indicate that agencies in states with state laws that are more restrictive or less rewarding to police collect more in federal equitable sharing. This finding supports the critics’ argument that police behavior in regard to forfeiture activities is influenced by the financial rewards and burdens involved.

Policy Implications

Our results reveal that the findings of investigative journalism and case study research, that is, that police forfeiture activities are influenced by financial rewards, may be more generalizable to law enforcement than previously thought. Despite recent state‐level reforms, federal equitable sharing and most state forfeiture laws provide limited due process protections and have minimal accountability or reporting requirements. Concerns about the impact of civil forfeiture practices on perceptions of procedural justice and police legitimacy are discussed, and possible policy reforms are reviewed.  相似文献
