The aim of this study was to examine if citizen science contributes to gaining insight into community health and to the health of the citizen scientists themselves. Therefore, thirteen citizens in four deprived neighbourhoods were trained as citizen scientists to conduct research in their own communities. Results showed that the citizen scientists identified forty (health related) themes in their communities. The citizen scientists reported an increase in their overall self-perceived health which, however, was not significantly demonstrated in the prequestionnaire and postquestionnaire. 相似文献

Smoking cessation reduces the risk of death, improves recovery, and reduces the risk of hospital readmission. Evidence and policy support hospital admission as an ideal time to deliver smoking-cessation interventions. However, this is not well implemented in practice. In this systematic review, the authors summarize the literature on smoking-cessation implementation strategies and evaluate their success to guide the implementation of best-practice smoking interventions into hospital settings. The CINAHL Complete, Embase, MEDLINE Complete, and PsycInfo databases were searched using terms associated with the following topics: smoking cessation, hospitals, and implementation. In total, 14,287 original records were identified and screened, resulting in 63 eligible articles from 56 studies. Data were extracted on the study characteristics, implementation strategies, and implementation outcomes. Implementation outcomes were guided by Proctor and colleagues' framework and included acceptability, adoption, appropriateness, cost, feasibility, fidelity, penetration, and sustainability. The findings demonstrate that studies predominantly focused on the training of staff to achieve implementation. Brief implementation approaches using a small number of implementation strategies were less successful and poorly sustained compared with well resourced and multicomponent approaches. Although brief implementation approaches may be viewed as advantageous because they are less resource-intensive, their capacity to change practice in a sustained way lacks evidence. Attempts to change clinician behavior or introduce new models of care are challenging in a short time frame, and implementation efforts should be designed for long-term success. There is a need to embrace strategic, well planned implementation approaches to embed smoking-cessation interventions into hospitals and to reap and sustain the benefits for people who smoke. 相似文献

Many community pharmacists ideologically support recent changes to their roles in primary healthcare. However, their antithetical resistance towards practice change could have systemic causes (i.e. role stresses), which may account for increased job dissatisfaction, burnout, and job turnover in the profession. Deeper comprehension was sought using a role theory framework.ObjectiveTo identify factors leading to role stresses and strain responses for community pharmacists, and to create a framework for community pharmacist role management.MethodPubMed, Scopus and Web of Science databases were searched for qualitative studies identifying community pharmacist role stress and strain using scoping review methodology from 1990 to 2019. Content and thematic analysis using the framework method was performed, and themes were reported using thematic synthesis.ResultsScreening of 10,880 records resulted in 33 studies identified, with 41 factors categorised into four domains: Interpersonal Interactions, Social Setting, Individual Attributes, and Extra-Role. All role stresses were present. Reported role strains suggest role system imbalance.ConclusionCommunity pharmacists are in a multifactorial transitional environment. Reported role stresses may be a function of past pharmacist roles and increased role expectations, amplified by many requisite interactions and individual pharmacist characteristics. Social science theories were found to be applicable to the community pharmacy setting. 相似文献

Applications of biomedical R&D currently imply substantial societal concerns. This paper explores, based on semi‐structured interviews with scientists in Norway, how biomedical researchers experience and tackle such concerns in their daily work. It shows how ritualised routine responses to dislocatory moments help maintain order in the daily work of the interviewed scientists; they do not address directly but instead smooth over concerns by a ritualised way of using ethics. This may foreclose substantive reflection and function as a stabiliser for ‘business as usual’. Overall, the current way of responding to concerns as described by the interviewees may contribute to a depoliticisation of important issues. The paper contributes to sociological work on ethics by linking it to recent discussions on Responsible Research and Innovation (RRI) and by the empirical research presented. The insights can also help improve science policies such as RRI. 相似文献

Researchers have recently demonstrated that group performance across tasks tends to be correlated, motivating the use of a single metric for the general collective intelligence of groups akin to general intelligence metrics for individuals. High general collective intelligence is achieved when a group performs well across a wide variety of tasks. A number of factors have been shown to be predictive of general collective intelligence, but there is sparse formal theory explaining the presence of correlations across tasks, betraying a fundamental gap in our understanding of what general collective intelligence is measuring. Here, we formally argue that general collective intelligence arises from groups achieving commitment to group goals, accurate shared beliefs, and coordinated actions. We then argue for the existence of generic mechanisms that help groups achieve these cognitive alignment conditions. The presence or absence of such mechanisms can potentially explain observed correlations in group performance across tasks. Under our view, general collective intelligence can be conceived as measuring group performance on classes of tasks that have particular combinations of cognitive alignment requirements. 相似文献

ABSTRACTRecent criticism of forensic science has focused on the fundamental aspects of the science, including the lack of supporting empirical studies, validation, accreditation, limitations and error rates. Proficiency tests are an essential component of accreditation and can be used to evaluate laboratory performance and identify systematic issues within components of the service provision. In 2016 we reported on the results of an analysis of 3176 CTS proficiency tests undertaken between 2005 and 2015 by Australian government service providers. The data analysed represented 43 unique CTS test types and covered 21 disciplines. Here we present further data from 2016 to 2017 and compare these results with those obtained from the previous study. These combined results further demonstrate that errors exist even though practitioners know they are examining proficiency tests and the tests undergo a review process. This study illustrates the need to continue to monitor trends in proficiency test results and also further highlights the need for well-designed, relevant, blind error rate studies to determine the approximate error rates for casework. 相似文献

ABSTRACTFemales are underrepresented in science, technology, engineering and mathematics (STEM) at all levels of society. Fewer females are completing STEM school subjects, graduating with STEM degrees, being employed as STEM professionals, and holding senior leadership and academic positions in STEM. However, unlike almost every other STEM discipline, the overall ratio of females is higher in many forensic science disciplines. For our sector, rather than having difficulty in attracting females, the bigger issue is how we retain and promote female talent. This complex issue is exacerbated by: gender pay gaps; family role expectations; lack of visible role models or mentors; discrimination and harassment; and bias during recruitment and promotion practices. We discuss barriers relevant for women in the forensic industry and offer potential solutions. These include flexible work arrangements, sponsorship programmes, and fostering and practising an inclusive workplace culture. Gender equity programmes and exemplar STEM organizations focused on a commitment to gender parity will be explored. Harnessing untapped female talent is as much a social justice issue as employing best practices for improving the quality, diversity and output of our forensic science workforce, and research and innovation strategies. 相似文献
