Assessing the publication output in the field of forensic science and legal medicine using Web of Science database from 2011 to 2020

The aim of this study was threefold. First, it analyzed the characteristics of the publication outputs for the Legal Medicine (LM) category using the Web of Science (WoS) database during 2011–2020. Second, it discussed the distribution of the papers for the 25 most productive countries/regions in terms of quality and quantity, such as the h-index and GDP per capita. Finally, it investigated the trend and temporal stability of the journal impact factor (JIF) and determined the percentage of the journal self-citations. The findings suggested that the number of papers, the average number of pages of the papers, the average number of cited references in the papers, the average number of authors per paper, the percentage of open access papers, as well as international and domestic collaboration tended to increase regularly. However, the productivity was limited when compared to the whole WoS database, since there was no significant change in the number of the journals. The countries/regions with the highest number of publications were not those that made the most impact in terms of the widespread impact of the publications. The level of international cooperation and the funding for the research had dramatic impact on the visibility of papers. The average JIF has increased significantly while the journal self-citation rates have decreased in a similar way. The journals have had very stable (have not fluctuated) impact factors over time. During the period studied, the journals with the higher impact factors (Q1, Q2) published many more papers than journals with the lower impact factors (Q3, Q4).     

87例大脑及脑干挫伤HSP70变化的研究

目的探讨人大脑及脑干挫伤后神经细胞HSP70变化与损伤时间的关系及大脑与脑干HSP70变化的差异。方法对87例闭合性颅脑损伤死亡脑挫伤组织进行病理学及HSP70免疫组织化学染色,结果进行图像分析。结果脑挫伤24h后.HSP70阳性神经细胞最多见,且免疫反应性最强,随后逐渐下降,14d组及30d组HSP70表达与对照组类似。脑挫伤部位可见较多HSP70阳性的淀粉样小体。图像分析显示大脑与脑干HSP70阳性细胞3个参数(A、IOD及AOD)之间呈高度显著正相关或显著正相关,由高至低排列为:A>IOD>AOD。结论神经细胞HSP70免疫组化染色结合图像分析技术作为推断脑挫伤经过时间的参考,大脑与脑干挫伤后神经细胞HSP70变化规律基本一致,但脑挫伤灶周围淀粉样小体形成的意义有待于进一步研究。     

对农村妇女信教问题的分析与思考

农村基层组织薄弱、思想政治工作淡化、精神文化生活贫乏以及妇女自身科技文化素质偏低等是女性信教者增多的主要原因.女性信教者增多已经干扰了农村两大文明建设,直接影响到当前农村社会的发展与稳定.解决农村妇女信教问题要突出农村思想政治教育的科学性、可参与性、针对性和实效性等具体应对措施.     

新刑法第30条之价值与规范分析

新刑法第 30条是对我国以往单位犯罪刑事立法的一个重要总结 ,其价值在于 :明确提出“单位犯罪”概念 ,有助于统一认识 ;强调单位犯罪的法定性 ,体现了罪刑法定原则 ;提供认定单位犯罪的总则性标准 ,有助于遏制单位犯罪 ;肯定单位犯罪 ,符合世界刑法发展的潮流。为充分发挥其功能 ,科学把握其精神 ,正确指导司法实践 ,深入而理性地分析其规范含意确有必要

DNA recovery after sequential processing of latent fingerprints on copy paper

Forensic examiners must determine whether both latent fingerprint development and DNA profiling can be performed on the same area of an evidence item and, if only one is possible, which examination offers the best chance for identification. Latent fingerprints can be enhanced by targeting different components of fingerprint residues with sequential chemical treatments. This study investigated the effects of single-reagent and sequential latent fingerprint development processes on downstream DNA analysis to determine the point at which latent fingerprint development should be stopped to allow for DNA recovery. Latent fingerprints deposited on copy paper by one donor were developed using three sequential processes: 1,8-diazafluoren-9-one (DFO) → ninhydrin → physical developer (PD); 1,2-indanedione-zinc (IND-Zn) → ninhydrin → PD; and IND-Zn → ninhydrin → Oil Red O (ORO) → PD. Samples were examined after the addition of each chemical treatment. DNA was collected with cotton swabs, extracted, quantified, and amplified. DNA yields, peak heights, number of alleles obtained, and percentage of DNA profiles eligible for CODIS upload were examined. DNA profiles were obtained with varying degrees of success, depending on the number and type of treatments used for latent fingerprint development. The treatments that were found to be the least harmful to downstream DNA analysis were IND-Zn and IND-Zn/laser, and the most detrimental treatments were DFO, DFO/laser, and PD. In general, as the number of treatments increase, the opportunities for DNA loss or damage also increase, and it is preferable to use fewer treatments when developing latent fingerprints prior to downstream DNA processing.     

Why Foundations Flourish: A Comparative Policy Framework to Understand Policy Support for Foundations across Countries*

Abstract

Philanthropic foundations have bloomed since the 1990s, contributing to the expansion of third sectors worldwide. This research aims to contribute to the comparative analysis of the policy conditions that shape the development – size and structure – of foundation fields across countries. A framework for comparative policy analysis encompassing key dimensions of policy support – policy milestones, levers, and alternatives – is proposed and applied to five southwestern European countries. Results demonstrate that although Spain, France, Italy, Belgium, and Portugal have been traditionally clustered under the same corporatist foundation model, their foundation fields vary widely in terms of size, structure and institutional embeddedness.     

氢化物原子荧光法测定人发中砷含量的不确定度评定

目的评定氢化物原子荧光法测定人发中砷含量的不确定度。方法以人发标准样品为分析对象,依据化学分析中不确定度的评估指南等指导性文件,分析测定过程中砷含量测定值（C）、样品处理后的总体积（V）、样品称量值（m）以及重复测量（rep）等多个不确定度分量,计算检测结果的合成标准不确定度和扩展不确定度。结果本文方法测定人发中砷含量的不确定度评定结果为：人发样品中砷的含量为（0.57±0.06）mg/kg,置信概率（p）=95%,自由度（υeff）=4。结论本文方法测量不确定度的主要来源是重复性和校准曲线,测定结果在标准物质给出的含量范围之内。
