Abstract

Allocating 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

Five studies examined whether, in self-control dilemmas, individuals develop an implicit disposition to approach goals and avoid temptations, psychologically as well as physically. Using a method developed by A. K. Solarz (1960; see also K. L. Duckworth, J. A. Bargh, M. Garcia, & S. Chaiken, 2002), the authors assessed the time for pulling and pushing a lever in response to goal- and temptation-related stimuli (e.g., studying and partying). The results show that individuals offset the influence of tempting activities by automatically avoiding these stimuli (faster pushing responses) and by approaching stimuli related to an overarching goal (faster pulling responses). These implicit self-control dispositions varied as a function of the magnitude of the self-control conflict, itself defined by how strongly individuals were attracted to temptations and held the longer term goal. These dispositions were further shown to play a role in successful self-control.  相似文献

The current experiment examined whether adjusting-amount and adjusting-delay procedures provide equivalent measures of discounting. Pigeons' discounting on the two procedures was compared using a within-subject yoking technique in which the indifference point (number of pellets or time until reinforcement) obtained with one procedure determined the value of the corresponding variable in the yoked condition with the other procedure. Behavior on each procedure was well described by a hyperbolic discounting function. Results revealed no systematic differences in the degree of discounting as measured by the discounting rate parameter of the hyperbola in Experiment 1, which used 20-mg pellets. These results were replicated in Experiment 2 using smaller, 14-mg pellets, which potentially yield more precise measurement of indifference points on the adjusting-amount procedure. The finding that estimates of the k parameter in the hyperbolic discounting function obtained with one procedure did not differ systematically from estimates obtained from the same subjects with the other procedure represents strong support for the hypothesis that the same process underlies the discounting of delayed rewards on both adjusting-amount and adjusting-delay procedures.  相似文献

In his influential paper, ‘Why Was the Logic of Discovery Abandoned?’, Laudan contends that there has been no philosophical rationale for a logic of discovery since the emergence of consequentialism in the 19th century. It is the purpose of this paper to show that consequentialism does not involve the rejection of all types of logic of discovery. Laudan goes too far in his interpretation of the historical shift from generativism to consequentialism, and his claim that the context of pursuit belongs to neither discovery nor justification is based on narrow interpretations of the contexts of discovery and justification. As a result, Laudan draws unwarranted conclusions concerning both the early and contemporary defenders of a logic of discovery. A methodological logic of discovery—which involves self‐corrective methods of hypothesis generation that promote the long‐term goals of science and which require consequential support for justification—is a type of logic of discovery that survives the shift to consequentialism.  相似文献

Family environmental factors have been implicated in the development of delinquency and adolescent psychiatric disorders. We examined the association between psychiatric disorders and family environmental factors among female juvenile detainees. A hundred female juvenile detainees in a Malaysian rehabilitation center (12–17 years-old) were assessed using the Mini International Neuropsychiatric Interview for Child and Adolescent and the Family Environment Scale. Majority of participants (56 %) had a psychiatric disorder, the commonest being Disruptive Behavior Disorders (40 %) and Depressive Disorders (30 %). Multivariate analysis found younger age (OR 0.52; 95 % CI 0.29, 0.94), older maternal age (OR 1.15; 95 % CI 1.03, 1.28), family history of crime (OR 7.19; 95 % CI 1.05, 49.43), family environment i.e. achievement orientation (OR 1.11; 95 % CI 1.02, 1.20) and control (OR 1.12; 95 % CI 1.03, 1.22) as significant factors for psychiatric disorder. This study demonstrated the role of age (younger adolescent and older mother), family history of crime and family environment beyond socio-economic status in psychiatric morbidity among female juvenile detainees. Future larger studies are needed to clarify familial-genetic factors that may impact strategies for family-centric mental health interventions.  相似文献

In two experiments, we explored whether anecdotal stories influenced how individuals reasoned when evaluating scientific news articles. We additionally considered the role of education level and thinking dispositions on reasoning. Participants evaluated eight scientific news articles that drew questionable interpretations from the evidence. Overall, anecdotal stories decreased the ability to reason scientifically even when controlling for education level and thinking dispositions. Additionally, we found that article length was related to participants' ratings of the news articles. Our study demonstrates that anecdotes can discourage scientific reasoning while also pointing to the potential influence of article length on judgements of quality.  相似文献

Persistent intense yearning for the deceased is a core clinical feature of complicated grief (CG) that distinguishes it from other mental disorders that develop following loss. The Yearning in Situations of Loss Scale (YSL) is a recently developed assessment of yearning. To assess the psychometric properties of the YSL in those with CG, we administered the YSL, Inventory of Complicated Grief, and Quick Inventory of Depression Symptomatology to 303 treatment-seeking bereaved adults with CG. Our results suggest the YSL is a reliable assessment with acceptable convergent and discriminant validity as a measure of yearning in those with CG.  相似文献

The learning style myth is a commonly held myth that matching instruction to a student's “learning style” will result in improved learning, while providing mismatched instruction will result in suboptimal learning. The present study used a short online reasoning exercise about the efficacy of multimodal instruction to investigate the nature of learning styles beliefs. We aimed to: understand how learning style beliefs interact with beliefs about multimodal learning; characterize the potential complexity of learning style beliefs and understand how this short exercise might influence endorsements of learning styles. Many participants who believed in the learning style myth supported the efficacy of multimodal learning, and many were willing to revise their belief in the myth after the exercise. Personal experiences and worldviews were commonly cited as reasons for maintaining beliefs in learning styles. Findings reveal the complexity of learning style beliefs, and how they interact with evidence in previously undocumented ways.  相似文献

This study examined the role of attention at retrieval on the false recognition of emotional items using the Deese–Roediger–McDermott (DRM) paradigm. Previous research has shown that divided attention at test increases false remember judgements for neutral critical lures. However, no research has yet directly assessed emotional false memories when attention is manipulated at retrieval. To examine this, participants studied negative (low in valence and high in arousal) and neutral DRM lists and completed recognition tests under conditions of full and divided attention. Results revealed that divided attention at retrieval increased false remember judgements for all critical lures compared to retrieval under full attention, but in both retrieval conditions, false memories were greater for negative compared to neutral stimuli. We believe that this is due to reliance on a more easily accessible (meaning of the word) but less diagnostic form of source monitoring, amplified under conditions of divided attention.  相似文献

Abstract

Research on collaborative learning has focused on its potential to foster successful problem solving. Less attention, though, has been given to issues of equity. In this article, we investigate how inequity can become amplified and attenuated within collaborative learning through small interactional moves that accumulate to produce broader patterns of equity or inequity. Our theoretical perspective utilizes Boaler’s notion of relational equity and introduces what we term participatory equity. Research was conducted in a computer science course co-taught by the authors and taken by upper-elementary students. Data sources include audio recordings of students’ collaborative interactions, ethnographic field notes, student work, and student surveys. This article focuses on a single student, Jason, and his dyadic interactions, and builds upon our previous analyses of his interactions with four higher-performing partners. Findings reveal how the interplay between classroom structures and student enactments shaped two types of inequity during collaborative learning. We conclude by discussing implications for theorizing and analyzing equity and inequity, as well as pedagogical considerations for structuring collaborative learning to attenuate inequity.  相似文献
