So long as procreation continues to remain a central driving force in a marital relationship, and the family the very core of progressive society, efforts will be undertaken to expand the period of fecundity and combat infertility. Genetic planning and eugenic programming are more rational and humane alternatives to population regulation than death by famine and war. Genetic enhancement technologies and the scientific research undertaken to advance them should be viewed as not only aiding (or, sometimes resolving) the tragedy of infertility in family planning, but as a tool for enhancing the health of a Nation's citizens by engineering man's genetic weaknesses out of the line of inheritance. Put simply, healthier and genetically sound individuals have a much better opportunity for pursuing and achieving the "good life" and making a significant contribution to society's greater well being.  相似文献

ABSTRACT

In the Introduction to this special issue, I first provide an overview of the programme of 'de-extremification' and mass internment in Xinjiang since early 2017. I then situate this development against the ‘ideological turn’ in Chinese Communist Party policy under President Xi Jinping, highlighting the new emphasis on stability maintenance and ideational governance. Next, I explore experiences of (in)security in Uyghur communities in- and outside of Xinjiang in the era of internment to consider how far PRC counter-terrorism initiatives have now evolved into state terror. In doing so, I apply Ruth Blakeley's (2012) definition of state terror as a deliberate act of violence against civilians, or threat of violence where a climate of fear is already established by earlier acts of violence; as perpetrated by actors on behalf of or in conjunction with the state; as intended to induce extreme fear in target observers who identify with the victim; and as forcing the target audience to consider changing its behaviour. Finally, I discuss the six contributions to the special issue.  相似文献

A reversible technique is presented in which the root morphology of missing teeth in skeletonized human remains can be reconstructed for the purpose of radiographic comparison and postmortem identification. In this technique, which is based upon pilot studies with skeletonized mandibles of archival remains, the alveolar socket walls are sealed with a coat of cyanoacrylate cement and injected with a mixture of vinyl polysiloxane and barium sulfate. Radiographs are produced with the radiopaque mixture in place, which highlights the antemortem morphology of the roots. Subsequently, the impression material is removed, resulting in no gross alteration of the evidence. The radiographs made with this technique, as well as the impressions, can be stored for later use at a trial or pending the discovery of antemortem dental evidence.  相似文献

This ecological study examined the association between seven socioeconomic indicators (GDP, unemployment rate, female labor force participation rate, alcohol expenditure, marriage rate, percentage of births outside of marriage, and indictable crime rate) and total, male, and female rates of suicide and suicide plus undetermined death in Ireland during the period 1968-2000. Analysis of the data expressed as absolute values showed highly significant associations between the socioeconomic indicators and the total, male, and female suicide rates. However, these associations were explained by the strongly trended data. The trended nature of the data was removed by using year-to-year differences. Analysis of the first-differenced data showed that none of the socioeconomic indicators was associated with the total, male, or female suicide rates with the exception of indictable crime, which had a significant independent effect on the female suicide rate (coefficient = 2.0, p < .01) but not on suicide plus undetermined death. This study highlights the need to use econometric methods in time-trend analyses, the lack of age-sex specific exposure data in this area, and the challenge of understanding trends in suicide in their socioeconomic context.  相似文献

Jurors in negligence cases are supposed to judge a defendant by the reasonableness of his or her conduct and not by the consequences of that conduct. But several studies have shown that a cognitive heuristic known as hindsight bias can skew post hoc judgments of some prior behavior. Thus, jurors who must evaluate the actions of a defendant may be influenced inappropriately by the consequences of those actions. A complementary problem arises when jurors must evaluate the injuries incurred by the plaintiff. Here, jurors' knowledge about the defendant's allegedly negligent conduct can proactively influence their assessment of the plaintiff's injuries and determination of damages. The purpose of the present study was to examine the effectiveness of two procedural techniques intended to reduce or eliminate the impact of hindsight bias in negligence cases—multiple admonitions from a judge about the proper use of evidence—and bifurcation (actually withholding irrelevant evidence from jurors). We presented a re-enacted automobile negligence trial to 355 jury-eligible adults drawn from the community, varied the evidence and instructions that they heard, and measured liability judgments and damage awards from individual jurors both before and after deliberating, and from juries. Results showed that admonitions were generally ineffective in guiding jurors to the proper use of evidence but that bifurcation was relatively more effective. Deliberations had no curative effect on jurors' misapplication of evidence.  相似文献

The influence of crime among the elderly was investigated in this study. The study suggests that crime prevention programs among the elderly should be implemented with some reservations. Since the risks of criminal victimization are low among the elderly, it may not be possible to reduce those rates much further, even with elaborate security programs for the elderly. On the contrary, raising the salience of crime by placing great emphasis on preventive behavior may well foster social isolation among the elderly.  相似文献
