When considering the persuasive characteristics and prospective influences of Darwin-skeptic mass media, uncertainties remain about how to reciprocally promote evolutionary theory to skeptical audiences. This study aims to improve evolution advocacy by translating some of the most successful methods of science endorsement to Evolution Wars contexts. In particular, strategies used to address vaccine hesitancies and enhance immunization uptake policies are reinterpreted for those seeking to improve pro-evolution communications to religious publics. What results are three recommendation categories described as General Guiding Principles, Proximate Interventions, and Auxiliary Interventions. 相似文献

A great deal of research has investigated the performance consequences of affective experiences at work, but the mediating mechanisms that explain these consequences remain understudied. In this study, we used experience sampling method to examine within-person relationships between changes in affective states and episodic performance, as mediated by attentional allocation and regulation. Our findings show that within-person changes in negative affective states have a concurrent association with episodic performance as mediated by reduced attentional allocation and regulation, while positive affective states are associated with better performance, as mediated by enhanced attentional allocation and regulation. Our results are discussed in terms of their implications for understanding the performance and attentional consequences of affective states at work. 相似文献

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

Four experiments were conducted to explore how people allocate social resources between meritorious and needy parties. As predicted, participants with high social dominance orientation (SDO), who prefer hierarchical relationships in society, favored meritorious parties. In contrast, participants with low SDO, who value social equality, favored needy parties. Participants appealed to merit- or need-based ideologies to justify their allocations. Apparently, the notion of fairness denotes merit-based reasoning to people with high SDO, whereas it denotes need-based reasoning for those with low SDO. Among the participants, merit- and need-based ideologies were not simply post hoc rationalizations, but rather mediated the allocation decisions. Implications for the study of ideology and for theories of distributive justice are discussed. 相似文献

In the presence and absence of white noise, response-independent aversive events were delivered to rats according to several variable-time electric-shock schedules. The animals could switch from the noise component to the no-noise component and vice versa by making a single lever-press response. If the schedule in one component was not in operation when the animal was in the other component, the proportion of time allocated to one component equalled or matched the proportion of obtained punishers in the other component. If both schedules were always in operation, minimizing tended to occur: the animals allocated almost all of their time to the component having the lower shock rate. An analysis of these results, in terms of the expected time until an aversive event, is presented. 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

Gaucher disease is a rare, chronic,ethnic-specific genetic disorder affecting Jewsof Eastern European descent. It is extremelyexpensive to treat and presents difficultdilemmas for officials and patients in Israelwhere many patients live. First, high-cost,high-benefit, but low volume treatment forGaucher creates severe allocation dilemmas forpolicy makers. Allocation policies driven bycost effectiveness, age, opportunity or needmake it difficult to justify funding. Processoriented decision making based on terms of faircooperation or decisions invoking the ``rule ofrescue' risk discriminating against minoritieswho may already suffer from inequitabledistribution of heath care resources. Apartfrom cost, Gaucher disease prompts questionsabout abortion. Unlike severe geneticdisorders, Gaucher offers no grounds forabortion and, in many ways, is analogous togender based abortions that are prohibitedregardless of fetal age. Finally, Gaucherraises concerns about the disclosure of geneticinformation. These affect potential carriersasked to participate in population studies andcarriers and patients who must considerdisclosure to others. These concerns weigh theright to privacy against communal interests andbilateral commitments. 相似文献

Policies and position statements regarding decision-making for extremely premature babies exist in many countries and are often directive, focusing on parental choice and expected outcomes. These recommendations often state survival and handicap as reasons for optional intervention. The fact that such outcome statistics would not justify such approaches in other populations suggests that some other powerful factors are at work. The value of neonatal intensive care has been scrutinized far more than intensive care for older patients and suggests that neonatal care is held to a higher standard of justification. The relative value placed on the life of newborns, in particular the preterm, is less than expected by any objective medical data or any prevailing moral frameworks about the value of individual lives. Why do we feel less obligated to treat the premature baby? Do we put newborns in a special and lesser moral category? We explore this question from a legal and ethical perspective and offer several hypotheses pertaining to personhood, reproductive choices, “precious children,” and probable evolutionary and anthropological factors. 相似文献
