Aging studies on fingerprint residues using thin-layer and high performance liquid chromatography

The chemical substances of perspiration found in latent fingerprint residue may hold the key for dating latent fingerprints. To study the chemical transformations of these components as a function of time and environment, fingerprint residues from four males and four females were analysed by thin-layer chromatography (TLC) and high performance liquid chromatography (HPLC). Three major and two or three minor components were detected by both methods and the variation in the quantity of the major components with time was observed.     

证券虚假陈述民事责任性质之界定

虚假陈述是一种典型的证券欺诈行为,历来成为各国证券法规制的重点。我国2005年修改的《证券法》明确规定了虚假陈述的民事责任,但未明确责任的性质。本文从虚假陈述民事责任性质三种学说的评析入手,结合案例分析了我国实践中存在的问题,并提出了相应的解决办法。     

Sudden death due to unsuspected coronary vasculitis.

Coronary artery vasculitis is a well-recognized complication of polyarteritis nodosa and is occasionally seen in other forms of systemic vasculitis. However, involvement of the major epicardial coronary arteries leading to myocardial infarction and death is uncommon. Isolated coronary arteritis is even more rare. We report three cases of sudden death due to myocardial ischemia associated with arteritis of the major coronary arteries. All three decedents were previously healthy young to middle-aged men who had died suddenly after complaints of chest pain and shortness of breath. The autopsy findings and differential diagnoses are presented. Such cases are of particular interest to the medical examiner because of the sudden, unexpected nature of the deaths. An approach to the correct diagnosis is discussed.     

Young Chinese consumers' brand perception; the role of mianzi as moderator

The basic purpose of this study was to investigate the role of exposure and past experience on consumers' brand perception, as mediated by three variables (perceived quality, brand recall, and satisfaction) and moderated by mianzi. Using data collected from a survey of 331 customers, brand perception models for two diverse kinds of products (high and low involvement) were tested. SmartPLS structural equation modeling was applied to produce models for both types of products. Exposure and experience significantly influences brand perception in different product categories, which suggests that customers perceive both high and low involvement. Our study also established that mianzi has a significant moderating role in high‐involvement product category. Ultimately, the findings suggest significant differences in the brand perception of product types with respect to mianzi and the mediational role of perceived quality and satisfaction, providing a structure for future research on brand perception.     

An Empirical Investigation into Measurement and Determinants of Food Security

We examine the association between calorie-based indicators and experiential indicators of food security using data from slum households of Kolkata surveyed in 2010–2011. Experiential indicator is constructed following the United States Household Food Security Survey Module. Calorie based indicator is constructed using household-specific calorie norms. Modelling techniques take account of potential endogeneity in the relationship. The two indicators are aligned in the same direction implying more accurate targeting. However, there is a lack of one-to-one correspondence between the two measures and the drivers of calorie deprivation and food insecurity also differ, suggesting a one-size-fits-all policy cannot address both concerns simultaneously.     

VEP验光方法在常见眼外伤矫正视力检测中的应用研究

目的通过比较VEP验光、电脑验光及主觉插片验光在检测外伤眼屈光度中的关系,探讨VEP验光方法在外伤眼矫正视力中的应用价值。方法本组实验选取各种类型眼外伤患者,伤后3～6月经检查存在视力下降者61人(受检眼61只),分别对伤眼行电脑验光、主觉播片验光及VEP验光,比较三种验光方法所测屈光度及矫正视力之间的差异性。结果经统计学处理,VEP验光与主觉插片验光所测伤眼屈光度和矫正视力无显著性差异(P>0.05);电脑验光与主觉验光、VEP验光在球镜屈光度检查上存在显著性差异(P<0.05),在散光检查方面无明显差异(P>0.05);电脑验光所得矫正视力与主觉插片验光、VEP验光所得结果之间均存在显著性差异(P<0.05),尤其在角膜、虹膜睫状体、晶状体、玻璃体等部位损伤的受检眼中差异更为显著(P<0.01)。结论电脑验光和VEP验光均是客观的屈光检查方法,前者有方便迅速的优点,但其结果存在较大误差,特别是在屈光系统损伤的患者中误差更大,仅可作为屈光矫正的初步检查依据;而后者验光结果准确,能够反映伤眼的屈光实际情况,可以应用于法医学鉴定中的伤眼最佳矫正视力的评定。
