This study measured and assessed facial soft tissue depths (FSTDs) in adult female Chinese and New Zealand (NZ) Europeans (Caucasoids). Ultrasound was used to obtain depths at nine landmarks on 108 healthy subjects (51 Chinese, 57 NZ European), erect positioned, of same age group (18–29 years). Height and weight were also recorded. Statistical analysis focused on comparison of tissue depth between the two ancestry groups and the influence of Body Mass Index (BMI) (kg/m2). Results showed mean depth differences at Supra M2 and Infra M2 landmarks significantly greater for Chinese than Caucasoid women for all three BMI Classes (BMI <20, 20 ≤ BMI < 25, 25 ≤ BMI < 30), even BMI <20. For both groups BMI positively correlated with FSTD values at all landmarks except Labrale superius. This study enabled ancestry and BMI influence on FSTDs to be observed and compared for two distinct groups. Results add to knowledge about facial tissue depth variation.  相似文献

第四次全国少代会在全面总结少先队的光荣传统和基本经验的基础上,鲜明地提出了"在实践中体验"的教育原则.从心理学角度讲,所谓体验是受教育主体的一种情绪感受和情感想象,往往伴随着一系列心理表现,如服从、敬重、内疚、自责等,强调的是人的内心感受和主观情感.在少先队工作中大力提倡体验教育,就是要组织和引导少年儿童在亲身实践中,把做人做事的基本道理变成自己的一种行为习惯的过程.因此,体验是少先队工作的基本方法,也是少先队教育的重要目的之一.  相似文献

This paper examines the responsiveness of the balance of trade of the People's Republic of China to the real exchange rate. We find that, in both the short-run and the long-run, devaluation serves to improve the balance of trade. Using quarterly data for 1980:I to 1989:IV we show that the bulk of the response to devaluation occurs over a one year period, with noJ-curve effect. These results suggest that the two-tier price system and other measures to liberalize the Chinese economy have made the exchange rate an effective indirect tool for regulating trade.  相似文献

Forensic identification techniques include the examination of ID cards, the decedent's private belongings, fingerprints, footprints, lip marks, dental findings, red blood cell enzymes, performing photograph matching, facial reconstruction, visual identification, and DNA "fingerprinting." As part of forensic examinations, the identification of corpses that are fresh, decomposed, fragmented, or skeletonized as well as individual body parts and human remains can be requested. Identification becomes a challenging task for forensic terms particularly in mass-disaster situations. Each identification case should be considered to its own merit and the way to do that should be based on the effectiveness and cost of each method used. In Turkey, one of the major duties of the medicolegal system on the investigation of deaths is to identify the deceased if unknown.This study is undertaken to investigate the procedures, as well as their validities, used to deal with individualization of dismembered bodies directly sent to the Council of Forensic Medicine, Ministry of Justice, for autopsy and/or visual identification, as well as those received from peripheral districts for forensic identification. According to the Turkish Penal Procedural Law, a positive identification of the deceased is mandatory before performing an autopsy. According to the law, the ID cards are not taken to be sufficient for recognition of the deceased, and the major way of identification in daily practice is visual identification by a relative or any recognizant person to approve the identification to the prosecutor. If visual identification fails, fingerprints, dental x-rays or body x-rays, and DNA "fingerprinting" can be used to establish identity when compared with known records of the individual obtained by law enforcement.This retrospective study was carried out into 421 dismembered bodies, among 3063 autopsies performed in year 2002 by the Department of Morgue at the Council of Forensic Medicine, with particular insight into the identification procedures undertaken and their results. The overall negative identification rate was 30.4%, and in 1% of the cases, the visual identification by relatives were not confirmed by DNA identification and taken as misidentified.  相似文献

Using data from a recent ethnographic research project on microcredit, power, and poverty in the Chittagong Hill Tracts in Bangladesh, this article demonstrates that the relationship of women with both NGOs and male relatives is one of dependency and subordination. Gendered power relations, embedded in NGO practices and socio-cultural gender norms, influence the female borrowers to accept the domination of the fieldworkers and their male relatives. This article examines how and why NGOs create power inequalities between fieldworkers and female borrowers, why the fieldworkers dominate a group of women, and why these women continue to participate in microcredit programmes.  相似文献

When a person is wounded in Turkey, he first attends hospital for treatment. The hospital is responsible for a report describing his injuries and their treatment and prognosis. The patient is then scanned by a specialist in forensic medicine who provides a final official report. In that report the lesions, the prognosis (including whether the injuries are life threatening or not) and the projected days away from daily activity are shown. In this study 18,317 cases which were examined in the second and the third Specialization Board of the Council of Forensic Medicine during 1996 were analyzed. Among them 112 cases were dental injuries. Dental injuries are reviewed according to their sex, causation, detail of injury, and they are compared to other studies.  相似文献
