The success of the Child Support Enforcement Program has been questionable since its inception in 1975. This paper attempts to measure the success of the state CSE programs through the development of several performance measures.  相似文献

The backings of 90 black electrical tapes were analyzed to evaluate the chemical components of these films, the ability of individual techniques to discriminate samples, and the ability of the techniques combined to distinguish samples. The techniques utilized and their respective discrimination results were stereomicroscopy and physical measurements, to include observation of surface features of the backing, width, and thickness measurements (c. 64%); Fourier transform infrared spectroscopy (FTIR) using a microscope accessory (c. 83%); pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS; c. 81%); and scanning electron microscopy/energy-dispersive spectroscopy (SEM/EDS; c. 87%). Ninety-four percent of the backings were discriminated through this combination of analytical methods. Finally, evaluating these results in conjunction with previously published data on the analysis of the adhesives from the same set of electrical tapes provided an overall discrimination of nearly 96%.  相似文献

Abstract: Salivary DNA is encountered in many crimes, such as sexual assaults and murders. In this study, saliva from three male donors was deposited on the skin of three female recipients. The amount of male salivary DNA remaining on the female skin was measured over a 96‐h period using the Quantifiler? Y Human Male DNA Quantification Kit. In eight of the nine experiments, a full male DNA profile matching the donor was obtained even after 96 h. In addition, the study showed that the concentration of salivary DNA varied from donor to donor and from day to day. The efficiency of two recovery methods, wet and dry swabbing and minitaping, was compared. The results indicate the tapelift method gave higher DNA recovery. This study also examined the secondary transfer of salivary DNA from skin to fabrics. Cotton and polyester give higher DNA transfer than leather.  相似文献

Outlined in this article are the proposals of the oregon Task Force on Family Law. This interdisciplinary task force recommends early education in conflict resolution and preparation for marriage. Also recommended is a change of the language of divorce and a more streamlined, less adversarial system.  相似文献

The present study examined perceived family and peer influences on body dissatisfaction, weight loss, and binge eating behaviors in adolescents. Three hundred and six girls aged 11 to 17 years (M = 13.66, SD = 1.12) and 297 boys aged 11 to 18 years (M = 13.89, SD = 1.13) completed a questionnaire that examined the direct influence and quality of family and peer relationships on body dissatisfaction and disordered eating. Direct influences of family and peers, rather than the quality of these relationships, predicted body dissatisfaction and disordered eating in adolescent boys and girls. Interesting differences were found between girls and boys in the nature of the influences and in the way they were expressed. In particular, parental and peer discussion and encouragement of weight loss predicted disordered eating behaviors in girls, while maternal and peer encouragement predicted binge eating and weight loss behaviors in boys. Fathers played a salient role in the expression of more severe forms of eating problems, while siblings played a small yet significant role in cognitive restraint among girls. The findings highlight gender differences in the importance of significant others in the expression of body dissatisfaction and disordered eating in adolescence.  相似文献

In an attempt to reap the purported benefits that "knowledge workers" bring to organizations, many police departments have shifted to a community problem–oriented policing philosophy. Rather than focusing on enforcement and incarceration, this philosophy is based on the dissemination of information to promote a proactive, preventative approach to reduce crime and disorder. In keeping with much of the contemporary literature on the "learning organization" (sometimes called the "knowledge organization"), police departments hope to deter crime through the knowledge benefits that derive from information and its associated technologies. With goals to stimulate productivity, performance, and effectiveness, police departments across the country are employing information technology to turn police officers into problem solvers and to leverage their intellectual capital to preempt crime and neighborhood deterioration.
Many public and private organizations are striving to change their operations toward this same concept of the knowledge worker. Information technology is often touted as a vehicle for capturing, tracking, sorting, and providing information to advance knowledge, thus leading to improvements in service–delivery efforts. Based on an extensive study of police departments that have attempted to implement a knowledge–worker paradigm (supported by information technology initiatives), this research explores the feasibility, effectiveness, and limitations of information and technology in promoting the learning organization in the public sector.  相似文献
