Research teams have made considerable progress in treating absolute uterine factor infertility through uterus transplantation, though studies have differed on the choice of either deceased or living donors. While researchers continue to analyze the medical feasibility of both approaches, little attention has been paid to the ethics of using deceased versus living donors as well as the protections that must be in place for each. Both types of uterus donation also pose unique regulatory challenges, including how to allocate donated organs; whether the donor / donor's family has any rights to the uterus and resulting child; how to manage contact between the donor / donor's family, recipient, and resulting child; and how to track outcomes moving forward. 相似文献

ABSTRACTIndonesia is at significant risk for catastrophic natural disasters, including earthquakes, volcanic eruptions, and tsunamis. Few studies have examined psychological functioning following disaster exposure in Indonesia, the fourth most populous country in the world. This study assesses variables associated with posttraumatic stress and posttraumatic growth following a devastating earthquake in Central Java that ranks as one of the costliest in Indonesia. The participants were 85 men and women living in rural farming villages. Almost all (95%) experienced major home damage or total home destruction. Posttraumatic stress symptoms were associated with resource loss, depression, and concerns about future earthquakes. Participants reported moderate posttraumatic growth. Posttraumatic growth was associated with energy resource loss and social support. The findings support conservation of resources stress theory. The implications of the findings for intervention and recovery programs are discussed. 相似文献

社会两难的行为动机研究认为,害怕和贪婪是人们选择不合作的原因。信任的心理学研究为社会两难的合作行为提供了另一种观点,即害怕被利用的背后实际上体现了博弈者对对方的信任的缺失。鉴于传统社会两难范式存在难以区分信任和合作两个因素的问题,本研究设计了“信任一合作”二阶段模拟实验,通过操作重复信托博弈中的信息反馈,研究虚拟多人信托博弈中初始信任和基于经验的信任对随后的公共财物两难博弈中合作行为的影响,结果发现:(1)初始信任对基于经验的信任的建立具有一定的积极影响,但是它对合作行为的作用远不如随后的基于经验的信任;(2)基于经验的信任水平高的被试在随后的公共财物两难博弈中也表现出较高的合作行为。 相似文献

The main objective of this study is to settle a rigorous field of decision analysis for rubber tree clones selection. Nowadays, there does not exist any process based upon a rigorous method to select the best clone to be plant in order to get the highest return on investment. The only known selection method is to use the experience of different protagonists acting in the plantation. So, we need a tool that takes into account very important criteria in order to achieve the main objective. This goal is achieved by using multicriterion analysis methods to the clone selection. The ranking procedure uses Elimination and Choice Expressing the Reality (ELECTRE III). For each criterion, indifference and preference thresholds are determined after establishing the relative importance of each criterion including rubber tapping, cumulative production during 15 years, cumulative production between 15 and 25 years, wind resistance, disease resistance, physiological resistance, grafting and quality of the rubber.

Two studies were conducted to test a two-stage model of the psychological mechanisms underlying the overconsumption of scarce resources in small groups. The model proposes that members of groups sharing resources first anchor their consumption choices on an “equal-division” heuristic and then, given sufficient cognitive capacity, adjust their choices in a self-serving direction. The results from both studies support the model. The first study found that when faced with a common resource pool almost all group members expressed thoughts regarding equality; however, individuals with sufficient cognitive capacity requested more from the pool and expressed more task-relevant thoughts than individuals lacking the necessary cognitive resources. The second study provided additional support for the two-stage model by demonstrating that group members' cognitions occur in the order predicted by the model and by demonstrating that an individual difference, social value orientation, affects thought processes only when individuals are not experiencing high cognitive loads. Implications are discussed. 相似文献

Perelman's work has been very influential in various disciplines, among them philosophy, rhetoric and law. Especially the typology of argumentative schemes which he developed together with L. Olbrechts-Tyteca has been considered as an excellent classification of arguments in natural language. There are, however, some weaknesses of this typology which make its application to empirical research quite difficult, namely, the lack of explicitness and the absence of clear criteria of demarcation. Still, the typology is highly relevant for empirical research, if these weaknesses are removed. This is illustrated with an example: the scheme called the division of the whole into its parts by Perelman/Olbrechts-Tyteca is described explicitly and then applied to the analysis of a sample of everyday arguments (mostly taken from newspapers). 相似文献

Poverty impedes children's executive function (EF). Therefore, it is necessary to mitigate the negative effect of poverty by developing efficient interventions to improve poor children's cognitive function. In three studies, we examined whether high-level construals can improve EF among poor children in China. In Study 1, we observed a positive relationship between family socioeconomic status and children's EF, which was moderated by construal level (n = 206; Mage = 9.71; 45.6% girls). In Study 2a, we experimentally induced high- versus low-level construals and found that poor children with high-level construals exhibited better EF than those with low-level construals (n = 65; Mage = 11.32; 47.7% girls). However, the same intervention did not affect the performance of affluent children in Study 2b (n = 63; Mage = 10.54; 54% girls). Moreover, we found that the interventional effects of high-level construals improved the ability of children living in poverty to make healthy decisions and delayed gratification in Study 3 (n = 74; Mage = 11.10; 45.9% girls). These findings may have implications for using high-level construals as an effective intervention to improve poor children's EF and cognitive capacity. 相似文献

This contribution participates to the development of ergonomic contributions to the prevention of occupational risks in confined spaces, specifically in sewer pipe rehabilitation projects. The intervention deployed was structured around a participatory and collaborative approach involving all stakeholders in the project to sustainably improve the prevention of work-related accidents and musculoskeletal disorders among workers. Detailed analyses of workers’ activities coupled with a systemic analysis of the design and collective monitoring of the worksites were carried out. This made it possible to characterize the health and safety risks of site teams as products that compromise between several organizational requirements and situational constraints. Extended to the site manager, the analysis of his activity, although strategic, of anticipation and continuous design of intervention situations, proved to be limited by a vertical organization of the sites, which does not integrate his expertise. Based on the diagnosis, validated and shared by all, the prevention challenges were articulated with the performance objectives of the worksites in a perspective of co-design with and by the different hierarchical levels of the department. The intervention made it possible to collaboratively build new organizational rules that consider the concrete realities of the work of workers and site managers. 相似文献

AbstractAllocating access to unapproved COVID-19 drugs available via Pre-Approval Access pathways or Emergency Use Authorization raises unique challenges at the intersection of clinical care and research. In conditions of scarcity, prioritization approaches should minimize harm, maximize benefit, and promote fairness. To promote continued data collection, patients seeking access to unproven COVID-19 drugs should receive lower priority for allocation when they decline to participate in clinical trials, either of the requested drug or other investigational products, offering a comparable balance of risks and benefits; special attention should be paid to concerns of voluntariness and distrust. In addition, institutional treatment protocols that can contribute more robust real world data should be preferred to single patient requests for access, with priority for inclusion based on traditional clinical allocation criteria relying on available evidence. Fairness demands distribution of these protocols across a diverse range of sites, particularly those serving marginalized populations, among other protections. 相似文献
