Do people think individuals with Substance Use Disorder (SUD) have freewill? How does addiction science inform views on the issue? We distinguish between two senses of freewill: 1) libertarian freewill , in which freedom turns on a particular metaphysical conception of action (sometimes operationalized as “could have done otherwise”), and 2) compatibilist freewill , in which freedom depends on the relation between the actor's psychology and her actions (e.g., “was the act what she wanted to do?”). We argue that, in different ways, scientific accounts can impact conceived freewill by linking addictive behavior to mechanisms that observers view as peripheral to the actor ( motivation modularity) . While a variety of impacts on conceived compatibilist freewill are plausible, we argue that contemporary addiction science has no direct bearing on conceived libertarian freewill. Addiction science may, however, indirectly impact conceived libertarian freewill by priming an explanatory framework in which intention is superfluous (especially materialism). 相似文献

AbstractChina is home to approximately 245 million rural-to-urban migrant workers. The influx of migrants into urban areas has posed various challenges for local social service systems. Recently, increasing number of community services have been developed to meet the growing service demands from the migrant population. However, whether increase in community service use results in improved wellbeing among migrant workers remains critically unexplored. As such, this study examines the role of community service use in migrant workers’ life satisfaction and the potential mediating effect of identity integration in Shenzhen, China. Bootstrapped models were adopted to examine relationship among variables. Drawing from a sample of 1,087 rural-to-urban migrant workers, we found that community service use is positively correlated with both identity integration and migrant workers’ life satisfaction. Moreover, identity integration served as a partial mediator between community service use and life satisfaction. The mediating effect of identity integration was found to increase with age. This study highlights that diverse services should be implemented to address divergent needs of migrants in different age groups. Community service can also serve as a vehicle to foster integration among migrant workers in host communities, especially for older age groups. Future studies may further investigate the relationships between community social capital, community social support, quality of community-based organization and frequency of service use so as to optimize the life satisfaction of migrant workers. 相似文献

This review examines the current published and “grey” literature relating to the experiences of homelessness by people seeking asylum within Australia. While many people seeking asylum have experienced homelessness during their flight, inadequate and unaffordable housing are a feature of the settlement experience for a large number of new arrivals to Australia, putting at risk their successful settlement. This study aims to explore the factors influencing access to stable housing. A systematic review of the academic literature and a search of the grey literature identified 11 articles and 20 documents related to homelessness and people seeking asylum in Australia. The academic literature included a variety of methods and approaches to the investigation of the experience of homelessness in Australia. The grey literature was more practice based, including evaluation and research reports, submissions, and newsletters. Findings suggest that experiences of homelessness are multifaceted and have a range of influences, including policy, financial stress, lack of access to education and employment, and a lack of affordable and suitable housing. Any solutions to address homelessness need to be similarly diverse. Discrimination from real estate agents and employers was also identified as a barrier to housing for many people seeking asylum, an issue that will need to be addressed at a systematic level. The lack of research published in the academic literature means that although there may be some programmes or solutions operating in the community, as demonstrated in the grey literature, this information is not being shared beyond organisation websites or subscriber lists, resulting in a lack of coherency or sharing of solutions. This review highlights the need for further attention to the factors influencing homelessness in asylum seekers, the experience of homelessness, and how these can be addressed by government and non-government led strategies and policy development. 相似文献

This article uses ethnographic methods to explore how peer support and community involvement influence the mental health and well-being of transgender (or, trans) people in the southeastern United States. The study builds on existing research that suggests that trans community involvement and peer support among trans people enhance mental health experiences and moderate the effects of stigma and discrimination on health outcomes. Through qualitative analysis of 158 hours of participant observation and 33 in-depth interviews with members of a trans community organization in the U.S. Southeast, this paper identifies three key processes through which peer support and community involvement enhance the mental health and well-being of trans people: (1) the normalization of trans identities and experiences; (2) the creation of a social support network; and (3) the empowerment of trans people. 相似文献

We sought to evaluate the efficacy of successive matching training for establishing generalized reflexive matching across 4 children with autism. In Experiment 1, differential reinforcement with delay fading was efficacious in establishing “yes” and “no” matching and nonmatching responses in 2 participants when 2 identical or nonidentical picture stimuli were presented. In addition, emergent visual–visual reflexive relational responses were observed using novel picture stimuli in a transfer test phase. In Experiment 2, differential reinforcement alone was efficacious in establishing matching and nonmatching responses in the other 2 participants when 2 identical or nonidentical objects were presented. Transfer to identical objects presented through touch (i.e., tactile discrimination) was additionally observed for both participants. Procedures in the study were adapted from the PEAK Relational Training System to aid in clinical replication, and the translational results have implications for language training with individuals with autism. 相似文献

Creating a strong, influential third party has been an abiding aspiration on the American left, and were this goal to be achieved, it could be a great boon to subordinate groups in the United States. Yet widespread doubts persist, even among progressives that this is desirable, and especially that it is possible. Here, I briefly review compelling reasons for thinking otherwise; I then consider in some depth the potential for starting to build a viable left third party leading up to and after the pivotal 2020 election. In doing so, I go beyond the existing literature on third parties, which has yet to reflect systematically on progressive third party prospects in this period. Specifically, I assess how the emerging political environment may shape left third-party building, and I evaluate ongoing and developing attempts by key groups engaged in that effort. I find a distinct tension between conditions encouraging progressives to reform versus abandon the Democratic Party, and I identify one alternative party-building tendency that seems most able to exploit the latter impulse due to its already established electoral viability. Last, I highlight relevant questions that remain for activists hoping to create an effective national left third party. 相似文献
