The Assisted Reproductive Technologies (“ART”) have resulted in over eight million births to date, heralding remarkable advances in reproductive medicine with a transformational impact on both medicine and law. The effects have been acutely felt on the modern family, as well as on a myriad of areas of legal practice—including Family Law, Estate Planning, Contract, Health, Constitutional, Criminal, Discrimination, Tort Law and, for international arrangements, Immigration and Citizenship laws. This article examines the historical context, present impact, and future trends of ART and the Law. Its purpose is to help better understand these unique developments in order to help law and policy makers harness and craft the policies and frameworks that will be needed to monitor, shape and guide these remarkable possibilities for participants, professionals, law and society.  相似文献

The study presented in this paper aims at assessing how printed fingermarks can be used to generate realistic latent marks bearing varying quantities of materials to be detected. Considering dilution series of artificial sweat (eccrine secretion) and 1,2-indanedione/zinc as amino acid reagent, we assessed how printed marks behave in comparison to natural fingermarks provided by a set of 30 donors. The results were assessed in terms of relative intensity (contrast, luminescence) and expert grading (ridge details, overall quality). With regards to the set of 30 donors, this study brought a quantitative look to the influence of intra- and inter-variability on the relative intensity values observed when processing natural fingermarks. This provided new data to further understand the concept of “donorship”. With regards to the use of printed marks, it has been illustrated how dilution series of a concentrated solution allows covering a range of cases: unnatural marks (intensity values well above those obtained with donors), rich marks (corresponding to fingermarks left by good donors), and faint marks (associated with the kind of results observed with poor donors). Such a range of detection performance offers the possibility to generate fine-tuned detection exercises of varying difficulty levels. Printed items made of artificial sweat could hence constitute a valuable alternative to natural secretions in the context of education and proficiency testing.  相似文献

Leading police scholars and practitioners were asked to reflect on the most urgent issues that need to be addressed on the topic of use of force. Four themes emerged from their contributions: use of force and de-escalation training needs to improve and be evaluated; new ways of conceptualizing use of force encounters and better use of force response models need to be developed; the inequitable application of force, and how to remediate biases, needs to be more fully understood; and misconceptions about police use of force need to be identified and corrected. The highlighted topics serve as an agenda for future research. Such research should provide greater insight into when, where, and why force is used by police officers, and how it can be applied appropriately. If implemented, the practical recommendations included in the contributions should have a positive impact on police performance, public trust and confidence in the police, and citizen and officer safety.  相似文献

Studying dipterans at the scene of a death can provide essential information for interpreting the evidence and help to reconstruct the events happened to a corpse in the past. Molecular tools have been employed for identification at specific levels in the cases of cryptic species or poorly conserved specimens. Identification of specimens is essential in forensic entomology since each species has a specific growth rate, which determines the calculation of the minimum post mortem interval (minPMI). In addition, phylogeographic reconstruction within a species can help to differentiate the haplotypes from a geographic area, thereby helping to clarify the possible relocation of a corpse. The morphological identification of Sarcophagidae species is often difficult, especially for the females. This is an important Diptera family since some of its species are among the first to reach a corpse, especially in warm areas. In this study, we compared the sarcophagids found in human corpses in forensic cases in Alicante (southeast of Spain) with specimens collected from baited traps in the same area and surrounding provinces. In total, 189 specimens were collected, comprising 72 from forensic cases and 117 from baited traps. Molecular identification was conducted by sequencing the cox1 mitochondrial gene and analyzing the sequences using ABGD, GMYC, and BIN species delimitation methods. The median joining algorithm in the PopART program was used to construct phylogeographic networks. Eight species in the family Sarcophagidae were identified. The most widely collected species were Sarcophaga argyrostoma and Sarcophaga tibialis. The haplotype networks obtained for these species did not indicate a clear geographic distribution of haplotypes. The S. argyrostoma samples from Alcoy were clearly isolated. The results demonstrated that this method is useful for identifying Sarcophagidae samples in forensic investigations and it can be employed for minPMI estimation.  相似文献

Leadership is a matter of both intentions and perceptions, which do not necessarily always match. Because employees’ motivation and commitment are only affected by leadership if they notice it, employee‐perceived leadership is expected to have a stronger correlation with organizational performance than leader‐intended leadership. This expectation is tested for transformational and transactional leadership, as both types of practices are expected to increase performance. Using a sample of 1,621 teachers and 79 Danish high school principals, the authors find that leader‐intended and employee‐perceived transformational and transactional leadership are only weakly correlated and that only employee‐perceived leadership practices (both transformational and transactional) are significantly related to objectively measured school performance. The results show that it is important to distinguish between intended and perceived leadership and that leaders should be aware of how their practices are perceived.  相似文献

Though political scientists generally understand the origins of native‐born reactions to foreigners, less is known about how anti‐immigrant contexts trigger a political response within immigrant groups. I address this question by studying the connection between xenophobic rhetoric and Latino politics. I claim that xenophobic rhetoric raises the salience of ethnic identity and impugns its worth. This identity threat leads high‐identifying group members to engage in political efforts that assert their group's positive value, whereas low identifiers shun political opportunities to bolster their group's devaluation. I test these claims with an experiment embedded in a nationally representative opinion survey of Latino adults. In light of xenophobic rhetoric, I find that relative to low identifiers, high‐identifying Latinos become less politically trusting, more ethnocentric, and increasingly supportive of policies that emphasize ingroup pride. These results clarify xenophobic rhetoric's role in amplifying the influence of ethnic identity on immigrant politics.  相似文献

According to judicial precedents, administrators informed by their expertise can speak on issues of public concern under First Amendment protections. In one sense, they could dissent by working against their employers in an attempt to direct issues of public concern through an educational function. The power to act like a statesman in raising such issues allows administrators to lead from behind and in front, as long as certain judicial thresholds are met. However, the U.S. Supreme Court recently moved to tighten the scope of such activity. This article assesses how an ethic of dissent has been translated into a constitutional perspective that at first was moderately constrained and later became very restricted. While the move to limit an ethic of dissent provides necessary constraints, it also may have weakened administrators’ ability to perform necessary statesmanship acts rooted in guerrilla government to achieve the common good.  相似文献
