According to the antiascetic hypothesis, religiosity should be strongly related to behaviors that violate ascetic standards (getting drunk and using marijuana), but only weakly related to behaviors that violate social standards (violence and stealing). Using the second wave of the National Study of Youth and Religion, I tested the antiascetic hypothesis using a question about the most important basis for deciding what is morally right or wrong. Contrary to the antiascetic hypothesis, individuals who believe that God's law is the most important for deciding what is morally right or wrong, compared to those who believe that society is the most important, are not less likely to get drunk or use marijuana. Furthermore, for getting drunk and marijuana use, differences in behavior are not the result of different ethical standards (ascetic or social), but rather differences in the willingness to uphold those standards (is it OK to break moral rules).  相似文献

We can use radically different reference-schemes to generate the same truth-conditions for the sentences of a language. In this paper, we do three things. (1) Distinguish two arguments that deploy this observation to derive different conclusions. The first argues that reference is radically indeterminate: there is no fact of the matter what ordinary terms refer to. This threat is taken seriously and most contemporary metasemantic theories come with resources intended to rebut it. The second argues for radical parochialism about reference: it's a reflection of our parochial interests, rather than the nature of the subject matter, that our theorizing about language appeals to reference rather than another relation that generates the same truth-conditions. Rebuttals of the first argument cut no ice against the second, because radical parochialism is compatible with reference being determinate. (2) Argue that radical parochialism, like radical indeterminacy, would be shocking if true. (3) Argue that the case for radical parochialism turns on the explanatory purposes of “reference”-talk: on relatively “thin” conceptions, the argument goes through, and radical parochialism is (shockingly!) true; on richer conceptions, the argument can be blocked. We conclude that non-revisionists must endorse, and justify, a relatively rich conception of the explanatory purposes of “reference”-talk.  相似文献

American Indian/Alaska Native (AI/AN) communities are disproportionally impacted by the opioid overdose epidemic. There remains a dearth of research evaluating methods for effectively implementing treatments for opioid use disorder (OUD) within these communities. We describe proceedings from a 2-day Collaborative Board (CB) meeting tasked with developing an implementation intervention for AI/AN clinical programs to improve the delivery of medications to treat OUD (MOUD). The CB was comprised of Elders, cultural leaders, providers, individuals with lived experience with OUD, and researchers from over 25 communities, organizations, and academic institutions. Conversations were audio-recorded, transcribed, and coded by two academic researchers with interpretation oversight provided by the CB. These proceedings provided a foundation for ongoing CB work and a frame for developing the program-level implementation intervention using a strength-based and holistic model of OUD recovery and wellbeing. Topics of discussion posed to the CB included engagement and recovery strategies, integration of extended family traditions, and addressing stigma and building trust with providers and clients. Integration of traditional healing practices, ceremonies, and other cultural practices was recommended. The importance of centering AI/AN culture and involving family were highlighted as priorities for the intervention.  相似文献

Research shows that parents have a strong influence on the party preferences of their children. Yet little is known about how such preferences are transmitted in multiparty systems with weak party identification and high electoral volatility. We propose a model of intergenerational transmission that includes both direct effects of parents' party preferences on those of their children, as well as indirect effects through left–right and issue positions. We test this model with original survey data of Dutch adolescents (14–20 years old) and their parents (N = 751 adolescent-parent pairs). We find two paths through which parents exert influence on the party preferences of their adolescent children. On the first path, parental party preferences function as a direct predictor of adolescent party preferences. On the second path, adolescent left–right and issue positions function as a mediator between parental left–right and issue positions and adolescent party preferences, with the effect of left–right positions being stronger than that of issue positions. The frequency with which adolescents discuss political topics with their parents moderates these effects.  相似文献

The way politicians talk about minorities institutes the normative context of intergroup relations. We investigated how endorsement of different political discourses predicts donation and collective action intentions by majority members toward the Roma in five European countries. The survey was conducted online using samples demographically similar to the populations of Hungary, Slovakia, Romania, France, and Ireland (N = 5,054). First, results showed that accepting paternalistic discourse versus discourse promoting allyship were not distinguishable; both promoted higher moral inclusion which in turn predicted higher prosocial intentions. Second, donations (i.e., immediate relief) and collective action (i.e., social change action) were driven by identical factors. Third, acceptance of openly hostile political discourse neither predicted moral exclusion, nor lower prosocial intentions. In summary, our research provides important evidence that when it comes to Roma—non-Roma relations, the previously established distinction between solidarity intentions that aim to solidify status relations versus bring about social change is completely blurred, presumably because of the social context in which any positive message communicates moral inclusion challenging the hostile status quo.  相似文献

The capacity for a treatment to maintain its effects over time may be the most critical component of behavioral interventions for challenging behavior as treatments that fail to persist are likely to be of little value to society. We reviewed the quality and quantity of different types of post-intervention data for the treatment of challenging behavior in studies published over the last 7 years. We found that for the majority of participants at least one measure of maintenance, fading, or follow-up was reported but with limited information regarding the quality of those measures. Reports of secondary variables related to post-intervention data (e.g., latency to measurement) were also uncommon. We discuss possible explanations for the paucity of post-intervention data, barriers to obtaining post-intervention data, strategies for obtaining these data, and implications for the external validity of behavioral interventions for challenging behavior. We provide recommendations for increasing the probability that post-intervention data are included in applied research on challenging behavior.  相似文献

The present study used an adapted alternating treatment design to evaluate and compare the effects of video prompting (VP) and video prompting plus frequency building (VP + FB) to teach daily living skills to three adolescents with autism spectrum disorder. Results demonstrated all three students made substantial improvements over their baseline performance using VP and VP + FB. Furthermore, a strong intervention effect emerged for VP and VP + FB conditions when compared to the control task. However, in terms of one intervention proving superior to the other (e.g., VP to VP + FB), the data offer a mixed interpretation with VP + FB affecting changes better for two of the three students. The FB component in the VP + FB produced strong, consistent gains for all students in terms of retention.  相似文献

COVID-19 has abruptly and unexpectedly transformed nearly every aspect of work, including but not limited to increased unemployment rates and uncertainty regarding future job prospects. Response distortion has always been a concern given that many organizations rely on information that is self-reported by applicants regarding their potential employability (e.g., responses to self-reported personality instruments, resumes, interview responses). Drawing from the Valence-Instrumentality-Expectancy (VIE) theory of motivation, we propose that the uncertainty surrounding jobs may lead to amplified distorted responses on these measures in areas where COVID-19 was most salient. In a sample of 213 working adults [~50% female, age M = 38.48], the present study shows that increases in response distortion on a measure of conscientiousness were more pronounced as a function of (a) local COVID positivity rates and (b) job type, such that frontline workers distorted their responses the most. Findings are discussed in the context of VIE theory, personality measurement, and challenges with maintaining effective selection procedures.  相似文献

Longitudinal dyadic research provides significant benefits for our understanding of romantic couple relationships. In this systematic review, we begin by providing a broad overview of topical trends and approaches in longitudinal couple relationships research from 2002 through 2021. Then, we narrow our review to dyadic relationship quality articles, highlighting key themes as well as noting important gaps in the research. Using an intersectional perspective that acknowledges multiple ways that disadvantage, power, and oppression may be seen in both research and in couples' lived experience, we note prominent paradigms used in examining couple relationships, what types of questions have been most valued, and what groups and approaches are underrepresented in the literature. Most longitudinal couple relationships research is quantitative, relies on self-report approaches from American couples in the early-to-middle years of their relationships, concentrates more on negative aspects of relationships than positives, and takes a communication-satisfaction paradigm in studying couples. We see a clear need to increase the use of methodologies beyond self-report measures, conduct more studies with within-group minority, older adult, culturally-diverse, and context-specific samples to explore the diversity of relationships, and fully consider both strengths and positive processes in relationships as well as the challenges couples experience.  相似文献
