We investigated the co‐occurrence of and cross‐informant agreement on early adolescents’ shyness, unsociability, and avoidance measured by self‐ and peer reports for fifth to eighth graders (N = 383; 51% male) in the United States. Avoidance was significantly and positively associated with shyness and unsociability based on peer reports and self‐reports. Furthermore, 45% and 30% of peer‐ and self‐reported withdrawn adolescents had multiple motivations for withdrawal, suggesting prevalent co‐occurrence of withdrawal subtypes. Cross‐informant agreement was moderate for shyness and weak for unsociability and avoidance. We draw attention to the complexity of motivations underlying withdrawal, theorize about subtype co‐occurrence, and discuss challenges and opportunities related to peer‐reported unsociability and avoidance. 相似文献

Recovery of interdependent infrastructure networks in the presence of catastrophic failure is crucial to the economy and welfare of society. Recently, centralized methods have been developed to address optimal resource allocation in postdisaster recovery scenarios of interdependent infrastructure systems that minimize total cost. In real-world systems, however, multiple independent, possibly noncooperative, utility network controllers are responsible for making recovery decisions, resulting in suboptimal decentralized processes. With the goal of minimizing recovery cost, a best-case decentralized model allows controllers to develop a full recovery plan and negotiate until all parties are satisfied (an equilibrium is reached). Such a model is computationally intensive for planning and negotiating, and time is a crucial resource in postdisaster recovery scenarios. Furthermore, in this work, we prove this best-case decentralized negotiation process could continue indefinitely under certain conditions. Accounting for network controllers' urgency in repairing their system, we propose an ad hoc sequential game-theoretic model of interdependent infrastructure network recovery represented as a discrete time noncooperative game between network controllers that is guaranteed to converge to an equilibrium. We further reduce the computation time needed to find a solution by applying a best-response heuristic and prove bounds on ε-Nash equilibrium, where ε depends on problem inputs. We compare best-case and ad hoc models on an empirical interdependent infrastructure network in the presence of simulated earthquakes to demonstrate the extent of the tradeoff between optimality and computational efficiency. Our method provides a foundation for modeling sociotechnical systems in a way that mirrors restoration processes in practice. 相似文献

We introduce and solve a new class of “downward‐recursive” static portfolio choice problems. An individual simultaneously chooses among ranked stochastic options, and each choice is costly. In the motivational application, just one may be exercised from those that succeed. This often emerges in practice, such as when a student applies to many colleges or when a firm simultaneously tries several technologies. We show that such portfolio choice problems quite generally entail maximizing a submodular function of finite sets—which is NP‐hard in general. Still, we show that a greedy algorithm finds the optimal set, finding first the best singleton, then the best single addition to it, and so on. We show that the optimal choices are “less aggressive” than the sequentially optimal ones, but “more aggressive” than the best singletons. Also, the optimal set in general contains gaps. We provide some comparative statics results on the chosen set. 相似文献

High‐quality developmental science requires a reliable and representative stream of participants, yet recruiting infants at a satisfactory rate can be challenging. We recently developed a new recruitment technique: we invite parents to sign up for no‐strings‐attached playdates in our laboratory, where we provide toys, free coffee, and students to help entertain the children. We have consistently hosted 2–3 new parents per week via playdates. Approximately 88% of attending parents agreed to be contacted later about research, and 81% of those contacted returned for research appointments. This method has doubled the number of participants we run per week, improved our rapport with the local community, and provided an enhanced educational opportunity for students in our laboratory. We hope others find it similarly transformative. 相似文献

Sexual Minority Women and Alcohol: Intersections between drinking, relational contexts, stress and coping 总被引:1,自引:0,他引:1
Few studies explore sexual minority women's experiences and perceptions of alcohol. Qualitative interviews were conducted with six sexual minority women who reported having sought help for alcohol problems in the past and six who did not. Themes emerged in two broad areas: stressors that contributed to heavy or problem drinking and factors that enhanced coping and reduced both stress and problem use. Alcohol use across groups was framed in terms of social context (e.g., bar patronage), stress management, and addiction. The findings of the study underscore the importance of considering the role of alcohol in managing stress as well coping factors that may inform social service interventions. 相似文献

Goffman's Interaction Order at the Margins: Stigma,Role, and Normalization in the Outreach Encounter
Robin James Smith 《Symbolic Interaction》2011,34(3):357-376
This article considers Goffman's conceptualization of interaction order at the margins of society in encounters between urban welfare workers and their clients. Observations from these encounters demonstrate practices relating to the situated management of stigma and identity, and the accomplishment of role within these service encounters. A reading of Goffman's theoretical contribution lies in revealing how social actors and social structures are realized in situ within the constraints of the interaction order sui generis. The article discusses three aspects of the outreach encounter, namely, (1) the accomplishment of role and motive, (2) the sequential phases of the outreach encounter, and (3) “the normalization ritual,” and introduces the concept of willful disattention. 相似文献

Despite the increasingly widespread emphasis on the need for transparency in health‐care and elsewhere, there is limited evidence regarding the consequences of disclosing medical performance data. The evidence is disparate and has not been synthesised in a coherent way. This paper focuses on surgical performance, whose measurement is generally often seen as straight forward. It begins by outlining the context for understanding the publication of such data and then presents an analytical framework as a vehicle for conceptualising the nature of disclosure in surgery and health‐care more generally. The framework addresses key dimensions concerning one surgical specialty (cardiac surgery) and its relationship with a range of stakeholders in an English context. In particular, we examine the interaction between surgeons and between surgeons, patients, managers and policy‐makers. These relationships are framed in terms of choice and calculativeness, strategies and tactics, and trust, and need to be understood at micro, meso and macro levels. We conclude by considering how this framework provides a research agenda for a sociology of disclosure. 相似文献

AbstractTransgender youth experience a variety of risk and resilience factors that impact their wellbeing. However, the research on these factors rarely includes the personal perspectives or authority of transgender youth. To address this gap, we collaborated with a transgender youth advisory board to conduct qualitative interviews with 19 transgender youth (15–22?years-old). Participants lived in two Midwestern states to provide the perspective of transgender youth often missed by research. Data were analyzed using thematic analysis and resulted in three categories of advice: challenges are real, have pride, and you are not alone. Participants acknowledged that challenges are a salient aspect of growing up as a person who is transgender but provided advice for their peers to persevere, feel proud of their identities, and support development and wellbeing through connections to others. Findings provide important implications for practitioners working with transgender youth and researchers aiming to promote resilience and reduce risk. Additionally, providing opportunities for transgender youth to participate in research as the experts and share their perspectives may also help promote resilience. 相似文献
