    Size Matters (in Output-Sharing Groups): Voting to End the Tragedy of the Commons

    Individuals extracting common-pool resources in the field sometimes form output-sharing groups to avoid costs of crowding. In theory, if the right number of groups forms, Nash equilibrium aggregate effort should fall to the socially optimal level. Whether individuals manage to form the efficient number of groups and to invest within the chosen groups as theory predicts, however, has not been previously determined. We investigate these questions experimentally. We find that subjects do vote in most cases to divide themselves into the optimal number of output-sharing groups, and in addition do decrease the inefficiency significantly (by 50% to 71%). We did observe systematic departures from the theory when the group sizes are not predicted to induce socially optimal investment. Without exception these are in the direction of the socially optimal investment, confirming the tendency noted elsewhere in public goods experiments for subjects to be more ā€œother-regardingā€ than purely selfish.catch-sharing, common-pool resources, efficient private provision, free-riding, laboratory experiment, partnership solution

    Latina/o Conversion and Miracle-Seeking at a Buddhist Temple

    The growing diversification of the US Latino religiousā€™ experiences calls for scholarly attention beyond Protestant or Catholic categories. This study begins to answer this call. Using interview data with 26 Latinos collected over 2 years of observation at the True Lama Meditation Center (TLMC) in Houston, Texas, we describe how Latinos who convert to Buddhism or actively attend the temple while also continuing to attend Christian services (both Catholic and Protestant) see themselves and understand their religious identities and practices. We then explore the reasons for their conversion or changes in religious identities and practices through various theoretical lens. Although the majority of respondents now claim to be Buddhist, many did not switch religions but augmented or extended their religious identities and practices. Reasons for conversion to Buddhism or concurrent involvement at the temple and Buddhist faith practices include seeking material support and miracles and those seeking spiritual fulfillment they felt they were not getting in Christian faith practices

    Guilt, shame and expressed emotion in carers of people with long-term mental health difficulties:a systematic review

    Expressed emotion (EE) is a global index of familial emotional climate, whose primary components are emotional over-involvement (EOI) and critical comments (CC)/hostility. There is a strong theoretical rationale for hypothesising that carersā€™ guilt and shame may be differentially associated with their EOI and CC/hostility respectively. This systematic review investigates the magnitude of these theorised associations in carers of people with long-term mental health difficulties. Electronic searches (conducted in May 2016 across Medline, CINAHL, Embase, PsycINFO and ProQuest) were supplemented with iterative hand searches. Ten papers, reporting data from eight studies, were included. Risk of bias was assessed using a standardised checklist. Relevant data were extracted and synthesised narratively. EOI was positively associated with both guilt and shame, whereas CC/hostility was positively associated with shame. The strength of associations varied depending on whether or not guilt and shame were assessed within the context of the caring relationship. Based on these data, an argument can be made for the refinement, development and evaluation of systemic and individual interventions designed to target carersā€™ guilt and shame. However, more research is needed to clarify the strength of these associations and their direction of effect before firm conclusions can be drawn

    Women in the profession: an update on the gendered composition of the discipline and political science departments in the UK

    Get PDF
    This article updates and broadens research undertaken eight years ago on the status of women in UK political sciencei. As Bates et al. then argued (2012: 139-40), research on women in the discipline is important, not only because of issues of equality, justice and self-reflection within the discipline, but also because of the privileged role political scientists play in the creation and flow of knowledge about gender inequality and womenā€™s underrepresentation in positions of power, as well as other important political issues more generally

    Seven-Year Distress Trajectories in Uveal Melanoma Survivors

    ObjectiveSevere or persistent distress is associated with poorer quality of life in cancer survivors. Distress follows distinct trajectories within different population subgroups. Identifying characteristics and causes of trajectories can assist intervention development and targeting. In a 7-year study of uveal melanoma survivors, we aimed to characterize anxiety, depression, and fear of cancer recurrence (FCR) trajectories, and identify whether concerns about symptoms and functional problems over the first 3 years of survivorship predict memberships of high distress trajectories.MethodIn a closed cohort study, we used growth mixture modeling (GMM) to identify statistically optimal trajectories over 6-, 12-, 24-, 36-, 48-, 60-, 72-, and 84-month time point posttreatment in 475 patients. We then regressed trajectory memberships onto a 3-year series of measures of concerns about symptoms and functional problems, controlling demographic, clinical, and 6-month anxiety, depression, or FCR indicators.ResultsAnxiety, depression, and FCR were represented by two-class linear GMMs. The majority scored consistently low, but 17.5% showed consistently elevated anxiety, 10.9% consistently elevated depression, and 19.4% consistently elevated FCR. Higher anxiety trajectory membership was predicted by greater concerns about symptoms at 6 and 24 months, higher depression trajectory membership by symptoms at 24 months, and higher FCR trajectory membership by symptoms at 6 and 24 months and functional problems at 12 months.ConclusionsMuch of the burden of persistent distress in cancer patients falls on a small proportion of survivors. Concerns about symptoms and functional problems are potential risk factors for distress. (PsycInfo Database Record (c) 2023 APA, all rights reserved)

    The appropriation of endogenously provided common-pool resources

    Get PDF
    Abstract Because game theory suggests that the origin of a common-pool resource should not affect appropriation behavior, experimental studies of appropriation from common-pool resources generally presume resources are exogenously provided. However, behavioral economic research indicates that the origin of a resource may affect the use of that resource. We investigate the potential role of resource origin by considering the appropriation of a common-pool resource after users have determined its productive capacity through contributions. Results indicate that resource origin does not significantly influence aggregate appropriation levels but that endogenous resource provision leads to individual strategic behavior
