日本开发老年人力资源的经验及启示

在人口老龄化不断加剧的情况之下,社会发展将更多地依赖于老年人的积极参与。而且随着长寿社会的到来,老年人的参与愿望和参与能力都在提升。日本是世界上人口老龄化程度最高的国家,已进入人口减少和超老龄社会。人口下降和老龄化将带来劳动力减少问题,对日本整个社会的均衡和可持续发展产生严重影响。为了应对劳动力不足问题,日本不仅修改《老年人就业稳定法》逐渐延长退休年龄,保障老年人继续工作,而且开展老年志愿者活动积极为退休的老年人创造再就业的环境。     

Application of Enhanced Point Estimators to a Sample of In Vivo CT‐derived Facial Soft Tissue Thicknesses

Facial approximations based on facial soft tissue depth measurement tables often utilize the arithmetic mean as a central tendency estimator. Stephan et al. (J Forensic Sci 2013;58:1439) suggest that the shorth and 75‐shormax statistics are better suited to describe the central tendency of non‐normal soft tissue depth data, while also accommodating normal distributions. The shorth, 75‐shormax, arithmetic mean, and other central tendency estimators were evaluated using a CT ‐derived facial soft tissue depth dataset. Differences between arithmetic mean and shorth mean for the tissue depths examined ranged from 0 mm to +2.3 mm (average 0.6 mm). Differences between the arithmetic mean plus one standard deviation (to approximate the same data points covered by the 75‐shormax) and 75‐shormax values ranged from ?0.8 mm to +0.7 mm (average 0.2 mm). The results of this research suggest that few practical differences exist across the central tendency point estimators for the evaluated soft tissue depth dataset.     

Eye Movement Characteristics of Cooperation Degree during Image Completion Test in Psychiatric Impairment AssessmentCSCD

Objective: To explore the difference of eye movement characteristics between uncooperative and cooperative subjects with mental disorder after cerebral trauma. Methods: Thirty-nine subjects which needed psychiatric impairment assessment were selected. According to the binomial forced-choice digit memory test (BFDMT), all subjects were divided into cooperative and uncooperative groups. The subjects were asked to take the image completion test from Wechsler adult intelligence scale. Meanwhile, the data of eye movement track, fixation, saccade, pupil and blink were recorded by the track system of eye movement. Results: There were significantly differences (P<0.05) in the data of saccade between cooperative (10 cases) and uncooperative groups (29 cases). The frequency, time, amplitude, acceleration of saccadic in uncooperative group were significantly higher than cooperation group. The saccade latencies of cooperation group increased more than uncooperative group. There was a significant difference (P<0.05) in total discrete distance, average distance and total time of fixation between two groups, while the average duration time, number and frequency of fixation had no significantly difference (P>0.05) between two groups. And the blink frequency of cooperation group was higher than uncooperative group. Conclusion: Eye movement can be an objective index for the primary judgment of cooperation level. © 2017 by the Editorial Department of Journal of Forensic Medicine.     

印尼亚齐民族分离运动的原因及特点探讨(1966-2003)

印尼的亚齐有长期的反抗强权史、鲜明的民族文化特色和独特的社会结构.亚齐分离运动既是中央与地方利益分配不均的结果,又是印尼的世俗化政治与伊斯兰政治矛盾的结果,同时还是亚齐民族意识在全球化时代背景下得以复兴的表现.本文拟对诸方面进行综合性探讨,进而总结出这一运动的特点.     

俄罗斯的人口现状与普京新方针的制定

普京第 2次就任总统后,在其就职演说及随后向国会所做的致辞中,制定了发展经济、提高居民福利水平、消除贫困和军队的现代化等国家新的发展目标。俄罗斯人口的数量、密度、性别、民族构成及劳动力潜力的现状等人口因素对普京新方针带来了很大的影响。

Age estimation and the developing third molar tooth: an analysis of an Australian population using computed tomography

The third molar tooth is one of the few anatomical sites available for age estimation of unknown age individuals in the late adolescent years. Computed tomography (CT) images were assessed in an Australian population aged from 15 to 25 years for development trends, particularly concerning age estimation at the child/adult transition point of 18 years. The CT images were also compared to conventional radiographs to assess the developmental scoring agreement between the two and it was found that agreement of Demirjian scores between the two imaging modalities was excellent. The relatively wide age ranges (mean ± 2SD) indicate that the third molar is not a precise tool for age estimation (age ranges of 3-8 years) but is, however, a useful tool for discriminating the adult/child transition age of 18 years. In the current study 100% of females and 96% of males with completed roots were over 18 years of age.     

Confidence interval of the likelihood ratio associated with mixed stain DNA evidence

Likelihood ratios are necessary to properly interpret mixed stain DNA evidence. They can flexibly consider alternate hypotheses and can account for population substructure. The likelihood ratio should be seen as an estimate and not a fixed value, because the calculations are functions of allelic frequency estimates that were estimated from a small portion of the population. Current methods do not account for uncertainty in the likelihood ratio estimates and are therefore an incomplete picture of the strength of the evidence. We propose the use of a confidence interval to report the consequent variation of likelihood ratios. The confidence interval is calculated using the standard forensic likelihood ratio formulae and a variance estimate derived using the Taylor expansion. The formula is explained, and a computer program has been made available. Numeric work shows that the evidential strength of DNA profiles decreases as the variation among populations increases.
