家兔死后眼玻璃体液锌、镍含量与 PMI关系的研究 总被引:6,自引:3,他引:3
目的寻找一种精确推定PMI的方法。方法应用电感耦合等离子体质谱(ICP-MS),检测了家兔死后96小时内眼玻璃体液锌、镍元素含量,探讨其与PMI的相关性。结果家兔死后24h内眼玻璃体液锌、镍元素含量与PMI显著相关,可作为推定早期PMI的参考指标,其二项式回归方程分别为y=0.1404x2-1.3351x+3.8298(R2=0.9202)、y=0.0043x2-0.0596x+0.2665(R2=0.9103)。结论家兔眼玻璃体液中Zn、Ni元素含量变化是推定早期PMI的参考指标之一。 相似文献

骨骼种属鉴定的组织学研究 总被引:6,自引:1,他引:5
目的 探求骨骼残渣的种属鉴定的组织学方法。方法 对人体不同部位骨骼,及常见动物骨骼的 77张骨组织学切片,在光镜下进行了骨组织学形态学研究。结果 不同动物骨组织学的形态学特征存在明显差异,其主要差别有:内、外环骨板的形态和相对厚度;哈氏系统之间的骨板的形态和哈氏系统的大小;哈氏环层骨板的数量及骨陷窝的数量等。结论 骨组织学的特征,不仅可以区分人与动物骨骼的残渣,也可以对不同动物的骨骼残渣进行区分。 相似文献

Pathological changes of pancreas in 22 cases died of intoxication were studied and the mechanism was discussed. The results showed that: in death cases by eating of toxicants, the hemorrhage and necrosis of pancreas is extensive mainly in caput and corpus, while inhaling of carbon monoxide is focal in corpus and cauda. 相似文献

Ego identity development in the areas of occupational choice, religion, and political ideology was studied using Marcia's categorization system. The results indicated a significant increase in the frequency of the identity achiever status for occupational choice and corresponding decreases in the frequency of the moratorium and identity diffusion statuses. A significant decrease in the frequency of foreclosures on religion was also found. In those instances where students underwent an identity crisis, the probability of resolving it successfully was very high. High scores on the Cultural Sophistication scale of the College Student Questionnaire-Part 1 were found to be associated with presence in the identity achievement status. For students not in the achiever status as freshmen, an interest in various literary and art forms was predictive of becoming an achiever while in college.Received his Ph.D. from SUNY/Buffalo. Recent research has been mainly concerned with the development of ego identity and with techniques for resolving identity crises.Received his Ph.D. from Syracuse University.

Similarity of ego identity status, assessed by Marcia's four-category classification system, was related to interpersonal attraction. Using male and female college students as subjects, this study found that (1) while all judges preferred targets who had or who are undergoing a crisis to those who have not had a crisis, (2) diffuse judges preferred targets with no commitments to those with commitments, and (3) judges with commitments preferred a foreclosure target more than judges without commitments. Differential evaluations of the targets' intelligence, knowledge of current events, adjustment, and morality were also found. Results are discussed both in terms of previous research positively relating personality similarity to attraction and Erikson's theory of the relationship between ego identity development and intimacy in interpersonal relations. 相似文献

PR systems often are credited with producing more equitable outcomes between political parties and encouraging wider social group representation than majoritarian systems. Theory suggests that this should instill greater trust, efficacy, and faith in the political system. We assume that citizens disadvantaged by majoritarian rules (political minorities) will have a relatively greater shift toward positive attitudes about democracy following a transition from a majoritarian system to proportional representation. We employ panel data from the 1993–1996 New Zealand Election Study (NZES) to test hypotheses about the effects of electoral system change on attitudes about governmental responsiveness, trust in government, and political efficacy. We find that there is a general shift in mass opinion toward more positive attitudes on some measures of efficacy and responsiveness. Political minorities display a greater shift toward feelings of efficacy than other voters. 相似文献
