This article outlines how co-production might be understood as a utopian method, which both attends to and works against dominant inequalities. It suggests that it might be positioned ‘within, against, and beyond’ current configurations of power in academia and society more broadly. It develops this argument by drawing on recent research funded through the UK’s Connected Communities programme, led by the Arts and Humanities Research Council; and by attending to arguments from the field of Utopian Studies. It explores particular issues of power and control within the field of co-production, acknowledging that neoliberalism both constrains and co-opts such practice; and explores methodological and infrastructural issues such that its utopian potential might be realised.  相似文献

A patient- and family-centred approach in paediatric health care is important because parents are involved in making key decisions about their child’s health care and advocating for the best interest of the child. Parents and family members are increasingly turning to the internet to find and actively share information about their child’s health care. Twitter is one of many online platforms used by parents of children diagnosed with cancer to share information related to their child’s cancer experience. Existing research suggests that there is a need to better understand the motives for using Twitter for sharing content about a child’s cancer experience. Furthermore, there is a lack of theoretical frameworks for characterizing those motives. In this paper, we identify key themes of tweets posted by parents of children diagnosed with cancer and align those themes with motives inspired by the well-studied Everyday Life Information Seeking framework. We propose a new motive in addition to those associated with the framework and suggest that information can be shared for endogenous reasons as well as to meet the needs of others. This paper contributes an increased understanding of motives for sharing information about a child’s cancer journey and extends a theoretical framework for building further knowledge in this area.  相似文献

Existing research linking prior military employment with labor market outcomes has focused on comparing the relative income of veterans and nonveterans. However, people who join the armed forces are uniquely selected from the broader population, and the form and direction of selectivity has shifted over time, with differential enlistment rates by race, region, and socioeconomic status. Understanding changes in the demographic composition of enlistees and veterans has significant import for the study of social mobility, particularly given changes in the occupational structure since the mid-twentieth century and wage stagnation well into the new millennium. Furthermore, labor market polarization and increases in educational attainment since WWII raise additional concerns about the social origins of military personnel and their occupational trajectories after discharge. Using data from the National Longitudinal Surveys, we investigate how social background is linked to both income and occupational mobility among veterans from three cohorts of American men: World War II, Vietnam, and the All-Volunteer Force. We find few benefits for veterans, for either income or intergenerational occupational mobility, once social background is controlled, suggesting that selection into the armed forces largely governs outcomes in the civilian labor market. Our findings have significant importance for understanding civilian labor market outcomes and trajectories of social mobility during distinct phases of military staffing.  相似文献

Objective: To identify preferences for and use of short-acting hormonal (e.g., oral contraceptives, injectable contraception) or long-acting reversible contraception (LARC) among community college students in Texas. Participants: Female community college students, ages 18 to 24, at risk of pregnancy, sampled in Fall 2014 or Spring 2015 (N = 966). Methods: We assessed characteristics associated with preference for and use of short-acting hormonal or LARC methods (i.e., more-effective contraception). Results: 47% preferred short-acting hormonal methods and 21% preferred LARC, compared to 21% and 9%, respectively, who used these methods. A total of 63% of condom and withdrawal users and 78% of nonusers preferred a more effective method. Many noted cost and insurance barriers as reasons for not using their preferred more-effective method. Conclusions: Many young women in this sample who relied on less-effective methods preferred to use more-effective contraception. Reducing barriers could lead to higher uptake in this population at high risk of unintended pregnancy.  相似文献

Objective: The current study is aimed to evaluate college student residence as a unique risk factor for a range of negative health behaviors. Participants: We examined data from 63,555 students (66% females) from 157 campuses who completed the National College Health Assessment Survey in Spring 2011. Methods: Participants answered questions about the frequency of recent use of alcohol, tobacco, marijuana, and illicit drugs, as well as sexual risk behavior in the last 30 days. Sexual risk behaviors were operationalized as having unprotected vaginal sex (yes/no) and the number of sexual partners. Results: Logistic regression analyses revealed that living off-campus is a unique predictor of alcohol, tobacco, marijuana, and illicit drug use, as well as engaging in unprotected sex and a greater number of sexual partners (all ps <. 01). Conclusions: Students living off-campus exhibit more substance use and sexual risk behaviors than students living on-campus, independent of gender, age, or race.  相似文献

Background

Despite high-level evidence of the benefits of caseload midwifery for women and babies, little is known about specific practice arrangements, organisational barriers and facilitators, nor about workforce requirements of caseload. This paper explores how caseload models across Australia operate.

Methods

A national cross-sectional, online survey of maternity managers in public maternity hospitals with birthing services was undertaken. Only services with a caseload model are included in the analysis.

Findings

Of 253 eligible hospitals, 149 (63%) responded, of whom 44 (31%) had a caseload model. Operationalisation of caseload varied across the country. Most commonly, caseload midwives were required to work more than 0.5 EFT, have more than one year of experience and have the skills across the whole scope of practice. On average, midwives took a caseload of 35–40 women when full time, with reduced caseloads if caring for women at higher risk. Leave coverage was complex and often ad-hoc. Duration of home-based postnatal care varied and most commonly provided to six weeks. Women’s access to caseload care was impacted by many factors with geographical location and obstetric risk being most common.

Conclusion

Introducing, managing and operationalising caseload midwifery care is complex. Factors which may affect the expansion and availability of the model are multi-faceted and include staffing and model inclusion guidelines. Coverage of leave is a factor which appears particularly challenging and needs more focus.  相似文献

Future development in cities needs to manage increasing populations, climate‐related risks, and sustainable development objectives such as reducing greenhouse gas emissions. Planners therefore face a challenge of multidimensional, spatial optimization in order to balance potential tradeoffs and maximize synergies between risks and other objectives. To address this, a spatial optimization framework has been developed. This uses a spatially implemented genetic algorithm to generate a set of Pareto‐optimal results that provide planners with the best set of trade‐off spatial plans for six risk and sustainability objectives: (i) minimize heat risks, (ii) minimize flooding risks, (iii) minimize transport travel costs to minimize associated emissions, (iv) maximize brownfield development, (v) minimize urban sprawl, and (vi) prevent development of greenspace. The framework is applied to Greater London (U.K.) and shown to generate spatial development strategies that are optimal for specific objectives and differ significantly from the existing development strategies. In addition, the analysis reveals tradeoffs between different risks as well as between risk and sustainability objectives. While increases in heat or flood risk can be avoided, there are no strategies that do not increase at least one of these. Tradeoffs between risk and other sustainability objectives can be more severe, for example, minimizing heat risk is only possible if future development is allowed to sprawl significantly. The results highlight the importance of spatial structure in modulating risks and other sustainability objectives. However, not all planning objectives are suited to quantified optimization and so the results should form part of an evidence base to improve the delivery of risk and sustainability management in future urban development.  相似文献

The current study explored social work skills and competencies required for work on integrated health care teams. Semi-structured, qualitative individual interviews were conducted with social workers employed in integrated health care settings. Key themes emerged around existing social work strengths, further training that is needed for this work, and fundamental skills for effective team-based collaboration. Incorporation of content, such as the social work role in integrated health care settings, advocacy in team-based treatment delivery, and incorporating medical knowledge into the social work curriculum are key to strengthening the future workforce. Education strategies can include not only infusion of integrated health care material into existing courses but also micro- and macro-specific elective courses and a range of interprofessional learning opportunities.  相似文献

The study of marginalia has not been widely discussed in social sciences research and occupies a marginal space in terms of methodological legitimacy. We highlight the value of paying attention to the ways in which participants speak back to the researcher. This paper draws on marginalia found in surveys written or drawn by young people in classrooms across South Wales, demonstrating how various notes and marks made spontaneously by participants can tell us something important and worthwhile about how young people engage with research. We position marginalia as a manifestation of complex power dynamics in the research process that illuminate participants’ negotiation of complex and multiple subjectivities in the literal margins and between the lines of the survey pages. Whilst the sensitive and rigorous analysis of marginalia is fraught with ethical and methodological challenges, we argue that paying closer attention to marginalia presents an opportunity for deeper engagement with participants when undertaking survey research.  相似文献
