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     

TESTS OF NONLINEAR DYNAMICS IN U.S. HOMICIDE TIME SERIES,AND THEIR IMPLICATIONS*

Attempts to explain temporal patterns in U.S. homicide data usually assume that a linear process accounts for the variation. A nonlinear process is an obvious alternative, however, and reasonable arguments suggest that nonlinearity may in part underlie homicide series dynamics. This paper applies tests for nonlinearity to national time series of homicide rates and counts. The results provide relatively little evidence of nonlinear structure; instead, a linear (random walk) process appears to generate most of the change in the series. Although this supports the unstated assumptions of current theories, it also raises questions about why homicides should follow a linear time path in the first place.     

COURT CASELOADS,PLEA BARGAINS,AND CRIMINAL SANCTIONS: THE EFFECTS OF SECTION 17 P.C. IN CALIFORNIA*

In an effort to relieve its overburdened superior courts, California introduced a statutory amendment which allowed lesser felonies to be dealt with in lower-level courts. Using an interrupted time-series methodology, this study examines the impact of this change in law on caseloads, plea bargaining, conviction rates, and sentencing in the superior courts. After the statutory intervention there was a reduction in superior court caseloads, but the overall rate of plea bargaining remained relatively constant. However, there were substantial changes in types of plea bargains with a decline in fast pleas and a corresponding rise in slow pleas. It was also found that severity of sanctions was related to the changing caseload patterns. Policy and theoretical implications of these and other findings are discussed.     

尸体材料中对硫磷(1605)代谢产物氨基对硫磷的检测

本文报道了对硫磷(1605)中毒后其代谢产物氨基对硫磷的测定方法。检材中的氨基对硫磷经有机溶剂提取,用气相色谱(NPD)测定,在肝或血中的回收率皆在70％以上。本法适用于腐败组织中以检测氨基对硫磷来确定1605中毒。
