Engaging non-conventional gatekeepers such as the police presents both promises and perils. Although studies have relied on police data for researching suicide and other sensitive topics in Africa, there is a paucity of literature that explores or reflects on police gatekeeping and its research implications. This paper presents authors’ reflections on police gatekeeping in a qualitative suicide study in Accra, Ghana. The main observation is that the process was double-edged. On the one hand, it led to field delays and costs, (mis)apprehensions and positionality problems, and trust building challenges. On the other hand, it vouched for research(er) credibility, provided therapeutic openings, and facilitated the viability of research with the suicide bereaved. Sensitivity to research context, sensitising the police, and reinforcing ‘therapeutic-research discourse’ with participants, are recommended means for aligning participants’ goals to research goals and for achieving therapeutic disclosures. 相似文献

ABSTRACTThis paper will argue that 3D digital animation, unlike its 2D and stop-motion counterparts, currently lacks recognisable self-reflexive aesthetic devices through which the trace of animators’ labour can be made visible. It will open with a brief history of how animation has previously shown its workings; from the pencil-wielding hand of Émile Cohl to the opening seconds of South Park, plus the intentional and unintentional smears and multiples visible on animation cells. These devices will then be discussed in relation to Marx’s analysis of the commodity in Capital Vol. 1, and how the process of fetishisation is momentarily disrupted by imperfections in the object which have been caused by production errors. These faults reconnect the object to its producer through the trace of (imperfect) labour which remains visible on the surface. In animation, similar (albeit consciously made) ‘errors’ connect the perceptive viewer directly to the work of 2D or stop-motion animators. This paper will argue the need for an equivalent to emerge in 3D digital animation, as well as highlighting some contemporary animators testing and subverting the limits of 3D and sketching some possible ways these might encourage further formal innovations. 相似文献

Concepts relating to consumer behaviour are brought together with notions of the idyllic English rural community to begin examining the importance of material culture in the formation of attitudes towards the English village. The resulting commodification of rurality is examined with the help of case studies of producers and consumers of Sylvania, a ‘collectable toy’. 相似文献

Control‐based imputation for sensitivity analyses in informative censoring for recurrent event data 下载免费PDF全文

In clinical trials, missing data commonly arise through nonadherence to the randomized treatment or to study procedure. For trials in which recurrent event endpoints are of interests, conventional analyses using the proportional intensity model or the count model assume that the data are missing at random, which cannot be tested using the observed data alone. Thus, sensitivity analyses are recommended. We implement the control‐based multiple imputation as sensitivity analyses for the recurrent event data. We model the recurrent event using a piecewise exponential proportional intensity model with frailty and sample the parameters from the posterior distribution. We impute the number of events after dropped out and correct the variance estimation using a bootstrap procedure. We apply the method to an application of sitagliptin study. 相似文献

Objective: The purpose of this pilot study was to evaluate the Resilience and Coping Intervention (RCI) with college students. Participants: College students (aged 18–23) from a large Midwest US university who volunteered for a randomized controlled trial during the 2015 spring semester. Methods: College students were randomly assigned to an intervention (n = 64) or a control (n = 65) group. Intervention participants received three 45-minute RCI sessions over subsequent weeks. All participants completed pre- and post-intervention assessments at the beginning of Week 1 and end of Week 3. Student resilience, coping, hope, stress, depression, and anxiety were assessed. Results. RCI participants reported significantly more hope and less stress and depression from Week 1 to Week 3 compared with control participants. Results for resilience also approached statistical significance. Effect sizes were small to moderate. Conclusions: This study found preliminary evidence that RCI is an effective resilience intervention for use with college students. 相似文献

Objective: Due to the short life expectancy of black men, it is important to understand what impacts health behaviors in this group so that interventions and programs can be developed to improve their health behaviors which may help in increasing the life expectancy of black men. The purpose of this study was to understand what perceived barriers exist for black college men that prevent them from engaging in healthy behaviors. Participants and Methods: Thirty-five black male students at a southern Historically Black College and University participated in five focus groups and four interviews. A qualitative analysis was used to analyze data for similar themes and codes. Results: Perceived barriers to engaging in healthy behaviors appear to be influenced by image, food cost, and education. Cues to action for not engaging in healthy behaviors appear to be related to role models. Conclusions: Black college men are not adequately informed or educated about elements that can impact their health and how they can improve it. College administrators and researchers should develop interventions that include elements of increasing health knowledge and age-appropriate role models to improve health behavior change among this group. 相似文献

ABSTRACTThe aging of the United States population is creating an increased need for social workers and other helping professionals with training in gerontology. Recent estimates indicate that less than 3% of MSW students are enrolled in an aging concentration, as compared to 19% enrolled in children/youth concentrations. In addition, the phenomenon of a diverse baby boomer generation joining the ranks of persons age 65 and older has created a plethora of scholarship and curriculum development aimed at readying the aging network for the unprecedented growth of older persons. Social work can make unique professional contributions to the field of gerontology and older persons. This study asserts, however, that social work is not adequately prepared to practice in an increasingly diverse aging society. The social work profession has articulated commitments to acknowledging and affirming how diversity and culture shape the human experience and to developing social workers who can competently engage in research-informed practice and practice-informed research. However, there remains a need in social work education for more widespread use of culturally relevant pedagogies that can help achieve these goals. Informed by both the Afrocentric and Black perspectives, this study presents a content analysis of the curricula infused at two historically Black universities. The nature and extent of the contributions of historically Black universities to social work education is the focus of this article. The scope of this investigation also includes the identification of prominent Black social work educators and discusses the implications of these perspectives for more culturally informed gerontology curricula that promote culturally competent gerontological social workers. 相似文献
