The current study builds on prior research in an analysis of the relationship between monthly violent and property crime rates in New York City census tracks and the New York City Police Department’s highly contentious stop, question, and frisk (SQF) policy. We find that higher doses of SQF are associated with small crime reductions generally and specific crime reductions for stops of blacks, Hispanics, and whites. But the way the policy was implemented precludes strong causal conclusions. Now that a federal court has intervened and SQF is undergoing change, the court monitor, New York Police Department, and city officials should partner with researchers in experimental evaluations to determine the optimal mix and dosage of enforcement strategies that safeguard the rights and liberties of citizens while enhancing public safety. 相似文献

The goal of this paper was to examine and compare two different commercially available approaches to the determination of the relative quantities of autosomal and Y chromosomal DNA using real-time PCR. One, Quantifiler® Duo, utilizes a TaqMan® assay with single copy probes for both autosomal human and Y quantification. The other method, Plexor HY® utilizes a primer quenching assay with multi-copy probes for its quantification of autosomal human and Y chromosomal DNA. To test these approaches we have utilized the NIST Human DNA Quantitation Standard Reference Material 2372, a set of three different NIST human DNA quantification standards, to examine the precision, accuracy and sensitivity of the real-time PCR assays. We also examined data from both systems utilizing casework samples. The results show that both systems produced linear estimates for DNA quantity over a broad range of input DNA. However we did observe some apparent copy number effects when comparing the three different NIST standards which we attributed to issues with sequence variations in the different standards. Overall, the single copy approach provided better accuracy while the multi-copy approach produced better sensitivity. Thus the choice of which system to use should depend upon the goals of the user. 相似文献

An estimated 15.5 million American children are exposed to intimate partner violence (IPV) every year. Such exposure negatively impacts children’s health, development and academic performance and may also be accompanied by housing instability or homelessness. Children growing up with periods of homelessness or housing instability are at risk for many of the same detrimental outcomes as children exposed to IPV. To date there are few studies examining the interrelationships among IPV, housing instability and the impact of housing interventions on children’s well-being. The current qualitative, longitudinal study examined mothers’ perceptions of how receipt of flexible funding designed to increase their housing stability may have also impacted their children’s safety, stress, mood and behavior. Forty-two mothers in the Washington, D.C. metro area were interviewed three times over a six-month period about their own safety and housing stability, as well as their children’s. Ninety-five percent of the mothers and their children were housed at the six-month interview. Mothers described improvements in children’s stability and safety, decreases in children’s stress levels, and improvements to their mood and behavior. They also discussed the symbiotic relationship between their own stress and well-being, and their children’s. The provision of flexible funding to assist domestic violence survivors with their housing also collaterally impacted their children’s safety, stress, mood and behavior. 相似文献

Cystic fibrosis (CF) is a lethal genetic disease, yet improved care has extended the mean age of survival into the young adult years. Many of the surviving adolescents have respiratory and digestive problems which delay growth and sexual development. It has been suggested that the specter of fatal disease interferes with adjustment to adolescence. We administered the Offer Self-Image Questionnaire to three groups with mean height less than the fifth percentile: CF males aged 12–19 (n=16); CF females aged 12–19 (n=8); and otherwise healthy males with short stature and/or delayed puberty aged 13–19 (n=34). The values obtained were compared to published normative data for a large number of normal adolescents and a smaller number of adolescents actively undergoing treatment for emotional disorders. CF males showed an abnormal pattern of adjustment that could be considered comparable to disturbed males and to growth-delayed and sexually delayed males. The CF female group was concordant with the normal population, rather than with the emotionally disturbed population. Thus CF and pubertally delayed males have a self-perception of maladjustment to the psychologic problems of adolescence. This suggests that adjustment problems of the CF male may be related to growth retardation and pubertal delay, the social stigma of which may be more easily disguised in the female. This is important in health care, since recent evidence suggests that exemplary attention to medical compliance and nutrition may ameliorate some of the growth lag both in pubertal delay and CF.Postdoctoral medical research fellow in allergy, immunology, and respiratory disease at Children's Hospital at Stanford.

This study, which used a prospective as well as a retrospective methodology, examined the criminal records of 30 child molesters prior to, and up to 10 years after an index event of sexual abuse for which they were convicted: 73% had convictions for other offenses, 60% had convictions for offenses other than sex offenses, 50% had convictions for property offenses, 27% had convictions for offenses involving violence, and 23% had convictions for drug offenses. Offending levels for nonsex offenses were significantly higher than the general adult male population. Any theory concerning the dynamics of sex offending against children needs to account for the level of nonsex offenses committed by child molesters. 相似文献
