Ridge Width Correlations between Inked Prints and Powdered Latent Fingerprints

A methodology to estimate the time of latent fingerprint deposition would be of great value to law enforcement and courts. It has been observed that ridge topography changes as latent prints age, including the widths of ridges that could be measured as a function of time. Crime suspects are commonly identified using fingerprint databases that contain reference inked tenprints (flat and rolled impressions). These can be of interest in aging studies as they provide baseline information relating to the original (nonaged) ridges’ widths. In practice, the age of latent fingerprints could be estimated following a comparison process between the evidentiary aged print and the corresponding reference inked print. The present article explores possible correlations between inked and fresh latent fingerprints deposited on different substrates and visualized with TiO₂. The results indicate that the ridge width of flat inked prints is most similar to fresh latent fingerprints_, and these should be used as the comparison standard for future aging studies.     

Judges’ sentencing decisions with older offenders

Older offenders tend to be treated with more leniency in the criminal justice system. A number of studies show that older offenders are less likely to be incarcerated, and when they are incarcerated, are more likely to receive shorter sentences. However, to date, no research has directly examined why such leniency occurs. This study asked U.S. state trial court judges to reflect on their sentencing practices with older offenders and to rate the factors considered most important when sentencing this population. Responses were received from 212 judges. Only 31% of judges acknowledged treating older offenders with greater leniency. These judges also indicated that they predominantly rely on legal factors when making decisions about sentencing with older offenders rather than factors specifically associated with age. Only cognitive impairment was identified by judges as one of the five most important factors to consider when sentencing older offenders. These results are discussed in terms of judges’ awareness of how they weigh information to make legal decisions. The influence of judges’ age and attitudes about aging on sentencing decisions are also explored.     

应用HPLC研究蓝色签字笔迹字迹色痕光老化规律

目的对蓝色签字笔所形成的字迹色痕光老化规律进行研究。方法比对14种蓝色签字笔样品在暗处保存条件下、自然光照射及强灯光照射等老化条件下物理特征变化情况;使用高效液相色谱法,监测蓝色签字笔墨水中色料成分的变化情况,并寻找蓝色签字笔墨水字迹自然光老化规律。结果强灯光照射后出现外观明显的老化现象,暗处存放的样本存在较长的老化时限。在自然光照射下30天内,样品色料成分的相对含量均随时间发生两个阶段的变化。结论样本字迹的外观为鉴定蓝色签字笔墨水字迹的形成时间提供了重要的信息。结合HPLC分析结果,可以确认字迹是否经过光照人工老化,为字迹形成时间鉴定的重要参考依据。     

“银色浪潮”下我国人口政策与经济社会的发展

近20年来,世界人口老龄化问题日趋普遍,许多国家都在探讨其解决途径。而中国的人口老龄化问题却有其自身的历史和制度根源。文章在探讨我国人口老龄化形势的基础上,分析了计划生育政策对人口老龄化的影响,总结了三点政策调整的新思路。     

中国人口的最新动态与趋势 ——结合第七次全国人口普查数据的分析

人口普查不仅可以为人口研究,而且可以为国家制定相关的经济社会发展政策提供数据支撑,具有重要的意义.根据第七次全国人口普查资料,结合历年人口统计和以往各次普查数据,研究对中国最新人口态势和特点进行了详细的归纳与分析,发现我国人口的最新变化主要体现为:全国人口规模继续增长,但增长速度和幅度持续放缓,并向零增长和负增长趋近;...     

Justice and intergenerational relations: An introduction

Gerontologists have rarely considered the concept of social justice in their research. Instead, related but more specific questions about the social situation of the aged have been posed. This paper provides an overview of existing social psychological literature on justice and intergenerational relations as a context for the five other papers contained in this issue. The importance of intergenerational justice within the family, particularly when there is a caretaking relationship, is stressed. As well, the policy implications of a concern with intergenerational justice are considered. The Paper concludes with a recommendation that gerontology and social justice research be integrated more frequently in order to enrich both fields of study.     

老年社会关怀研究

老年社会关怀是以社会物质资源的代际合理配置及其对老龄群体的有效供给为基础,通过制度伦理建构来保障老龄群体的各项基本权益,并不断提升其生活质量的社会道德实践。它是厚生伦理的重要德目,是传承孝道的现实需要,是可持续性经济伦理发展新路。它具有多维性、辐射性、互主体性。家庭孝养、社区关怀、政府善治的有机统一编织成一张功能互补、责任共担的社会关怀之网。     

完善我国社会养老服务体系建设再思考——以陕西省为例

养老服务是社会保障制度的重要构成部分,是应对人口老龄化、保障和改善民生的重要途径。陕西省社会养老服务体系建设取得了显著成绩,也面临着诸多问题。加快推进社会养老服务体系建设必须优化供给结构,明确多元组织权责;开放运行系统,合理配置稀缺资源;拓展项目内容,践行文化养老理念;加强监督管理,提升养老质量水平。     

Sweet dreams are made of this: The need for narrowly tailored statutory protection for documented dreamers

The growing backlog of immigrant visa petitions and legal permanent resident adjustment applications is a harsh reality of the American dream. Dependent children of immigrants can wait decades for their parents' visas to become current, only to age out of dependent status before stepping foot on American soil. Dependent children of nonimmigrants seeking to become legal permanent residents age out before their parents' adjustment application is approved – leaving them at risk of removal. This Note proposes a temporary visa status for these dependents, allowing them to maintain legal status in America and remain with their parents.     

人口老龄化与老年人力资源开发研究——以扬州市老年人力资源为例

随着社会经济的发展,我国人口老龄化日益严重。人口老龄化对经济、政治、文化等方面都产生了重要的影响。本文认为开发老年人力资源是促进社会和谐、保障人力资源有效供给的有效手段,文章通过对我国当前老龄化数据分析,将扬州市的老年人口作为具体的研究对象,阐述我国老年人力资源开发的背景及现状,对现有养老模式进行分析,从而提出一种创新型的养老模式即"一院两制"的养老院,设计了一套针对这个养老院的管理信息系统,以实现我国老年人力资源的合理开发与有效利用。
