应用酶组化、免疫组化方法对创伤早期时间的研究

在法医学检案中,经常要对尸体上的损伤进行检验以确定生前伤或死后伤,并要鉴定损伤时间.损伤超过8小时者一般用常规组织学方法可以解决,但损伤后经过时间较短,单用组织学方法不能解决,如利用酶活性反应方法和利用在组织内细胞内进行特异、灵敏、稳定的抗原抗体反应,可以较准确鉴定损伤时间.Perper J. A. Raek Allio、Tanaka、Fatteh等报导用组织化学方法鉴定损伤时间,祝家镇、刘世仓教授近年来也有报道,但用免疫组化学方法来鉴定损伤后早期时间,就作者所知,国内、外未见报道,而FN在创伤愈合过程中的作用国内外已有报道.本文     

Applying a forensic actuarial assessment (the Violence Risk Appraisal Guide) to nonforensic patients

The actuarial Violence Risk Appraisal Guide (VRAG) was developed for male offenders where it has shown excellent replicability in many new forensic samples using officially recorded outcomes. Clinicians also make decisions, however, about the risk of interpersonal violence posed by nonforensic psychiatric patients of both sexes. Could an actuarial risk assessment developed for male forensic populations be used for a broader clientele? We modified the VRAG to permit evaluation using data from the MacArthur Violence Risk Assessment Study that included nonforensic male and female patients and primarily self-reported violence. The modified VRAG yielded a large effect size in the prediction of dichotomous postdischarge severe violence over 20 and 50 weeks. Accuracy of VRAG predictions was unrelated to sex. The results provide evidence about the robustness of comprehensive actuarial risk assessments and the generality of the personal factors that underlie violent behavior.     

Is the doctor in? The evolving role of organized medicine in health policy

Until recently, physicians were viewed as the dominant player in health policy. Now, however, they compete with many other effective interest groups. This article analyzes this changing role, and specifically how organized medicine has changed its approach to influencing health policy. The essay begins with a review of the reasons for the growth and subsequent decline of physicians' influence. This is followed by a case study of physician payment reform under Medicare, which illustrates the ways in which organized medicine chooses when and when not to cooperate with government. The article concludes with a discussion of where physicians are likely to continue to be influential in future health policy reform. Three such areas are noted: payment policy, quality and clinical innovation, and medical education and training.     

The Role of Social Support in Students’ Perceived Abilities and Attitudes Toward Math and Science

Social cognitive models examining academic and career outcomes emphasize constructs such as attitude, interest, and self-efficacy as key factors affecting students’ pursuit of STEM (science, technology, engineering and math) courses and careers. The current research examines another under-researched component of social cognitive models: social support, and the relationship between this component and attitude and self-efficacy in math and science. A large cross-sectional design was used gathering data from 1,552 participants in four adolescent school settings from 5th grade to early college (41 % female, 80 % white). Students completed measures of perceived social support from parents, teachers and friends as well as their perceived ability and attitudes toward math and science. Fifth grade and college students reported higher levels of support from teachers and friends when compared to students at other grade levels. In addition, students who perceived greater social support for math and science from parents, teachers, and friends reported better attitudes and had higher perceptions of their abilities in math and science. Lastly, structural equation modeling revealed that social support had both a direct effect on math and science perceived abilities and an indirect effect mediated through math and science attitudes. Findings suggest that students who perceive greater social support for math and science from parents, teachers, and friends have more positive attitudes toward math and science and a higher sense of their own competence in these subjects.     

Using recidivism data to evaluate project 12-ways: An ecobehavioral approach to the treatment and prevention of child abuse and neglect

Many programs and projects have been remiss at looking at outcome variables such as recidivistic child abuse and neglect. Presented here are program evaluation data which examine recidivism data over 5 years across more than 700 families. Families receiving services from Project 12-Ways, a multifaceted in-home ecobehavioral approach, were compared with families indicated in the same region who received child protective services other than those offered by Project 12-Ways. Families who receive services from Project 12-Ways are less likely to reinjure or neglect their children again.     

Violent Sex Offenses: How are They Best Measured from Official Records?

In the United States, sexually violent predator (SVP) commitment statutes generally require assessment of an offender's risk of subsequent sexual violence. Current actuarial methods for predicting sexual reoffending were actually designed to predict something else—charges or convictions for offenses deemed sexual based on information obtained from police “rapsheets” alone. This study examined the referral and past offenses of 177 sex offenders. Results showed that police rapsheets (and data based on them) underestimated the number and severity of sexually motivated violent offenses for which sex offenders were actually apprehended. Rapsheet violent offenses seemed a more accurate index of the conduct addressed by SVP legislation than were rapsheet sex offenses. We suggest that, when evaluating sex offenders for SVP status, actuarial instruments designed to predict violent recidivism (as measured by rapsheet violent reoffenses) might be preferable to those designed to predict sexual recidivism (as measured by rapsheet sexual reoffenses).
