Abstract

Whether children benefit from being raised in a home owned by their parents has important policy implications and has been the topic of much scholarly debate. We match Panel Study of Income Dynamics data with census tract data to examine the impact of childhood experiences on adult outcomes for children followed over three decades. This allows us to document a wide range of characteristics.

For children born between 1968 and 1974, we analyze data on their first 18 years and also various outcomes when they are between 25 and 31 in 1999. We control for a comprehensive set of observable parental characteristics and develop a method to control for unobservable child characteristics together with an instrumental variable for the remaining selection problems. Parental homeownership status and children's college education and home‐ownership status are closely related, although the former is generated partially by the greater residential stability associated with homeownership.  相似文献

The aim of this study was to investigate whether or not the Nolla method is appropriate for Turkish children for the determination of the dental age (DA). A group of 719 children between the ages of 6 and 18 years were included in the study. DAs from orthopantograms by the Nolla method were estimated. The results obtained were compared with chronologic age (CA). Paired t and the Wilcoxon tests were performed. Both genders were underestimated in dental maturity when compared with the reference samples in total (-0.3 years) (p<0.01). The differences in girls were statistically significant in total and in all groups except for 7-7.9. The differences in boys between the CAs and DAs were not statistically significant in total and in all groups except for 7-7.9 and 8-8.9. Although the accuracy of this method was suitable for boys, according to our findings, it was not suitable for girls.  相似文献

Twenty-eight non-fatal cases of TV related injuries were noted in San Diego in the 2 years prior to September 2008. We reviewed the scene, witness reports, past history, and autopsy findings from three fatal cases and distinguished them from abusive head trauma. The recent literature was also reviewed. Our fatal cases resulted from TVs falling on small children and causing severe head injury. The literature review showed increasing injuries and deaths relating to TV tip-over, TV stands and dressers. Most of the fatalities were head injuries in small children. The reporting methods may not be complete or accurate. Some authors in the literature review suggested preventive measures so as to decrease these injuries. Forensic scientists should become familiar with these injuries and measures so that they may communicate effectively with their communities.  相似文献

发达国家及国际组织纷纷认识到了通过对金融系统资金交易进行监控,利用了解客户身份、保持记录制度、大额和可疑交易报告制度等反洗钱制度来发现犯罪线索、截留犯罪收益、追查犯罪嫌疑人的重要性。许多犯罪涉及到犯罪资金的流动,经侦、刑侦、禁毒、反恐等侦查部门应充分认识到反洗钱情报在侦查中的重要作用,通过建立包含金融、税务、海关、公安...  相似文献

The major issues of medico-legal relevance in fatal falls from a height are the manner of death and the reconstruction of the event. We present a peculiar case of a fatal fall from a height of about 9 m, involving a 27-year-old woman. At the death scene investigation, no suicide notes, housebreaking marks, or signs of fight were found, thus weakening both the suicide and homicide hypotheses. Combining circumstantial, autopsy and toxicology data, the kinematic analysis of the jump/fall, and the histological evidence of a myocardial sarcoidosis involving the left ventricle, we hypothesized that the young woman might have accidentally fallen from the window because of a sudden loss of consciousness related to cardiac disease undiagnosed during life. We believe that our brief report is a good example of the powerful additional information that histological investigations can offer for reconstructing the dynamics of the event in falls from a height and other traumatic fatalities.  相似文献

An otherwise healthy male infant was brought to the hospital because the mother suspected superficial infection at the operative site 5 days after an inguinal hernia repair. He was admitted to the pediatric unit overnight to be evaluated by his surgeon the next morning. When a venous infusion of maintenance fluids was started, the patient immediately went into cardio-respiratory arrest and was pronounced dead after resuscitation efforts failed. Subsequently, air collections were found in both venous and arterial circulations, including the splenoportal system. Detailed review of the clinical presentation and course, laboratory results, radiological, and pathological findings, along with a review of pertinent literature provides an explanation for the death by air embolism. Apparent inconsistent findings both radiographically and at autopsy are resolved. The mechanism of distribution of air to both systemic and splenoportal circulation is discussed. We believe this to be only the eighth case reported in English-language literature of infantile death from peripheral venous infusion. In all age groups, we find only six other cases in the English-language literature of gas found concomitantly in both the systemic and portal venous systems.  相似文献

儿童免受性侵害的权利--对我国儿童性法律的审视   总被引:1,自引:0,他引:1       下载免费PDF全文

在国际法上 ,性越来越与人权联系在一起 ,越来越被视为一种基本人权 ,性法律逐步从主要维护性秩序转向主要保护个人的性人权。《儿童权利公约》就突出体现了性人权的视角。我国已经批准《儿童权利公约》和《〈儿童权利公约〉关于买卖儿童、儿童卖淫和儿童色情制品问题的任择议定书》。在性人权的视角下 ,我国儿童性法律存在明显的缺陷与不足。儿童性法律的修改 ,应朝着更加人权化的方向进行 ,以便从一个侧面推动我国的人权建设。  相似文献

物权请求权与占有保护请求权在权利基础、权利主体、行使目的、举证责任、诉讼程序以及是否适用消灭时效等方面均存在不同 ;物权请求权与损害赔偿请求权在目的与功能、权利基础、损害的要求、归责原则、责任方式以及是否适用诉讼时效等方面存在着明显的不同 ;不当得利返还请求权与物权返还请求权、损害赔偿请求权既有相同之处 ,也有不同之处。在上述请求权发生竞合的情况下 ,应当允许物权人选择于其有利的一种加以行使。在一定条件下 ,物权请求权会发生向损害赔偿请求权和不当得利返还请求权的转化。  相似文献

16至19世纪的空想社会主义者全盘否定资本主义,主观地割断资本主义与社会主义的历史联系,否认资本主义是社会主义的基础,因此他们的理想社会只能是空中楼阁.20世纪的社会主义者为了抵制资本主义的侵蚀,拒绝利用资本主义的文明成果,但又急于赶超资本主义,因此也曾空想萌动.尽管二者存在本质的区别,但在"两制"关系上的认识误区,使它们都陷入了空想的怪圈.只有正确认识"两制"关系,科学设定过渡时期,大胆利用资本主义,才能彻底告别空想,使社会主义始终循着科学的轨道前进.  相似文献

类比推理虽然获得的是或然的结论,但其“触类旁通”的作用在侦查工作中能帮助侦查人员打开思路,认清案情,同时还有助于侦查假说的提出。在侦查工作中,还可以采用模拟类比的方法。  相似文献
