大鼠尸僵发展过程中肌节长度的变化及其长度测定

目的观察大鼠尸僵发展过程中肌节形态、肌节长度的变化。方法 2 1只大鼠分为 3组 ,每组大鼠分别于死后立即和死后 2h、 4h、 6h、 8h、 12h、 2 4h取材 ,扫描电镜下观察大鼠死后不同时间的肌节形态 ,同时测定肌节长度。结果死后立即取材标本肌原纤维松散 ,纤维间有一定的间隙 ;死后 2h ,肌原纤维间界限模糊 ,出现周期性横纹 ;死后 4h、 6h横纹清晰 ;死后 12h肌原纤维断裂 ,仍可见横纹 ;死后 2 4h肌原纤维断裂、融合。各组大鼠肌节长度与同组立即取材时比较 ,死后 2h、 4h、 6h、 8h均显著变短 (P值均小于 0 0 0 1) ,其中死后 4～ 6h最短 ;死后12h均无显著性差异 (P值均大于 0 0 5 ) ;死后 2 4h ,组 1、组 3无显著性差异 (P值均大于 0 0 5 ) ,组 2差异显著(P值为 0 0 0 7)。结论用扫描电镜测定肌节长度 ,发现肌节长度随尸僵经过时间的延长而发生变化     

躯体创伤或瘢痕面积与长度折算关系的探讨

在法医实践中发现,现有的伤残鉴定标准中未就体表创口或瘢痕面积与长度测量的换算作出任何规定,对某些体表损伤的伤残评定可能有欠公允。有必要就此提出相应的解决办法,供同行探讨。     

Assessing the potential of bacterial DNA profiling for forensic soil comparisons

A pilot study was undertaken to evaluate DNA profiling of the bacterial community in soil as an alternative to geological methods for forensic soil comparisons. Soil samples from three different ecosystems were compared, and the variation within and between ecologically different sites was determined by using terminal restriction fragment (TRF) analysis of 16S ribosomal DNA. Comparison of TRF profiles revealed that samples from within a specific ecosystem (e.g., a field) showed a significantly higher similarity to each other than to those from another ecosystem (e.g., a forest). In addition, some profile features were unique to specific ecosystems. These features may allow the determination of characteristic profiles that will facilitate identification of ecologically different sites, so that a given sample collected from a suspect could be identified as originating from, for example, a field, rather than a forest. The implications of these preliminary findings for forensic investigations are discussed.     

利用手长、足长估计人体身高和体重

本文对600名汉族青年男女进行了体格测量调查。通过对数据的统计学处理,分别建立以手长、足长推算人体身高、体重的回归方程。经回代分析表明,以手长、足长推算身长结果理想,而用以推测体重则误差较长。     

Trust in elections and the institutional design of electoral authorities: Evidence from Latin America

It is often assumed that the institutional organization of electoral management bodies (EMB) has an impact on the credibility of elections, but this proposition has been difficult to verify empirically. I examine whether the degree of autonomy from the political process of EMB administrators affects attitudes towards elections among citizens and legislators by analyzing mass and elite surveys across Latin America. I conclude that levels of confidence in the electoral process among political elites are higher in countries with politically autonomous EMBs, but this effect is muted in the analysis of citizen attitudes. This association holds after controlling for individual-level determinants of trust in elections and for other relevant country-level predictors in multilevel statistical models.     

Non‐Departmental Public Bodies Under the Howard Governments1

There has been both continuity and change in the use of non‐departmental public bodies (NDPBs) during the Howard years. In terms of continuity, the statutory authority and its incorporated version, the statutory corporation (in whose development late 19th and early 20th century Australian governments played such an important part), have remained in wide use. In terms of change, however, two other NDPB forms offered some challenge to its popularity. The government‐owned company came to be a preferred form for government business enterprises (GBEs) and, more recently, for many other non‐commercial public activities as well. And the executive agency, first making its Australian appearance in 1999, seemed initially to be another significant challenger, but its numbers, never great, were soon cut back. The article examines these trends, relating them to several relevant systemic inquiries and policy changes, notably the Humphry review of the governance of GBEs, the final settlement (in 1997) of the package of financial management acts, the Uhrig inquiry of 2003 and the system‐challenging pressures that have followed it. Commonwealth participation in joint (Commonwealth/subnational and Commonwealth/private) activities is also noted, as is the lack of ‘fit’ of the Australian experience with international theorising about ‘agencification’. Finally, the article seeks to identify the leading figures within the Howard governments who have been directing both the changes and the continuities involved in these developments.     

新药专利保护期限国际化法律冲突研究

Ocular findings in pediatric deaths under 2 years of age (1994-2004)

Abstract:  Our purpose is to highlight novel ocular findings of 102 forensic pediatric cases under 2 years of age who die suddenly. Forensic information, grossing, and microscopic eye protocol was followed. The most common diagnosis was Sudden Infant Death Syndrome (SIDS) (57/102). Novel cytoid bodies were present in the retina of 72/102 cases and they were located predominantly 90% (65/72) at the anterior part of the retina ( p  < 0.001). Of the SIDS cases, 85% (47/57) showed the presence of cytoid bodies, and among all diagnosis, SIDS was the most associated with cytoid bodies ( p  = 0.003). A second observation was extramedullary hematopoiesis (EMH) identified in 35/102 cases and 22 of the 57 SIDS cases. The most frequent EMH location was the choroids (29/35). This study is the first to demonstrate the presence of cytoid bodies and extramedullary hematopoiesis in the retinas of SIDS cases and children who die suddenly from other causes.     

Coping with complexity: Ballot position effects in the Finnish open-list proportional representation system

Many studies show that the order of candidates’ names on the ballot has an effect on voting. Less informed and indifferent voters may simplify the voting process by using the ballot position of candidates as a voting cue. By studying six parliamentary elections in Finland, this study first demonstrates that the relationship between ballot position and preference votes follows a reversed J-shaped curve. Candidates listed early on the ballot win the most preference votes, while candidates listed near the end have an advantage over those listed in the middle. Furthermore, the ballot position effect grows stronger with the complexity of the electoral environment. The ballot position effect increases as the number of candidates on the party list increases, the candidates-to-seats ratio increases and the number of incumbents on the list decreases.     

1950～1970年几个不同年代女性同期群婚姻及家庭生活管窥--基于人口学视角

从中国传统婚姻模式———普婚的视角切入，跟踪考察新中国成立以来1950年代、1960年代和1970年代几个不同年代初婚同期群女性的初婚持续时间及婚姻现况，得出的结论是：其一，新中国成立以来中国女性不仅一直沿袭普婚的传统婚姻模式，且初婚持续时间及婚姻关系保持不变的时间一般至终老，如果没有死亡这个不可抗力因素，60％左右的中国女性守望初婚并有偶者能够长达50年之久，且几个年代女性同期群均基本如此。其二，守望婚姻其实更本质的是守望家庭，对现阶段的老年女性而言，婚姻和家庭是唯一能够维持她们老年生活的基本保障。微薄的或几乎为零的养老金对她们而言，不如守望婚姻、守望家庭更可靠。养老是中国女性沿袭并不断维护传统婚姻模式的最重要的因素。即使在21世纪的头一二十年，这个基本事实仍然存在，这个基本判断仍然没有过时。
