Health research literature on quality and safety in recent years has pointed to a need to explore the characteristics of interdisciplinary team work unique to the health care sector and the particular organization. The literature also has identified a need for scientific models that explore and integrate existing findings concerning team dynamics. In this article, I attempt to address these concerns by developing and validating a scientific model for exploring safe work practices of interdisciplinary OR teams. Specifically, existing health research literature on quality and safety is reviewed to identify and incorporate various team-related aspects into dimensions of the proposed model. To further validate the model, I conduct an ethnographic study of safe work practices within an interdisciplinary OR setting. I find that safe work practices can be viewed as a product of the individual’s and team’s ability to draw on and combine explicit and tacit knowledge repertoires, which again is a product of the particular inner and outer structural conditions of a system. While the findings add their own unique distinctiveness to the scientific model, the findings also compare to the existing aspects and dimensions of the model. I conclude that the fit of the empirical data to the model improves the validity of the model, and also the potential application of the model in ethnographic research within different medical and/or team settings. 相似文献

石油修井作业机钢丝绳断裂失效研究 总被引:1,自引:0,他引:1
石油修井作业机钢丝绳断裂失效给人身安全和设备带来了很大的安全风险。我们分析了钢丝绳断裂机理,对采样进行综合研究认为:钢丝绳断裂的直接原因是在用钢丝绳在断裂前的脆性断丝数远远超过标准规定的报废要求,即该绳"带病工作",承载力严重降低,在过大的解卡载荷下,剩余钢丝不足以承受工作载荷,而导致断裂。笔者建议在今后的修井作业过程中,定期对钢丝绳和轮槽进行检查,及时更换不满足使用要求的钢丝绳、轮槽;钢丝绳使用过程中采用合理的润滑方法进行维护;在钢丝绳保存和转运期间,避免对钢丝绳造成损伤影响使用寿命;对于轮式修井机改用钢芯钢丝绳,避免结构破坏;鉴于卷筒旋向,今后应改用右捻钢丝绳。在修井作业过程中,解卡作业严禁超负荷施工。 相似文献

基于人机工程学研究思路,把消防灭火系统中人的因素分解为可用度、可信度和固有能力,筛选出温度和工作时间作为影响因子,利用层次分析法和线性回归法确定了消防灭火人力系统的可信度和固有能力,结合某消防支队训练统计数据对此研究方法进行了实例分析.结果表明,温度和工作时间对人力系统存在明显影响,相比之下,工作时间的影响较大,但消防灭火系统人的因素的决定因子是人力系统的固有能力,即灭火人员的业务能力、身体素质、心理素质和火场作风.此方法的提出对于消防灭火战斗效能评估、灭火力量组织和配置有着重要意义. 相似文献

以系统安全理论的观点和方法,通过建立人机环境系统物理模型,剖析两类危险有害因素诱发事故的机理,阐述危险有害因素在生产系统中不同影响程度和情况.将生产系统划分为本质安全型、风险型、危险型和危机型四种形式,并与之对应将安全管理分为本质安全管理、风险预控管理、隐患排查治理和应急响应管理四个等级.进而提出推行“以风险预控为核心、以隐患排查治理为基础、以应急响应为补充、以本质安全为目标”的“四位一体”安全管理模式. 相似文献

Despite sustained scholarly interest in post‐conflict states, there has not been a thorough review and analysis of associated methodology and the challenges of conducting research in these contexts. Addressing this gap, this paper directs attention to the particular effects of these settings on access and data quality and their ramifications for the resulting scholarship. It assesses the intrinsic challenges of performing fieldwork in these environments, drawing on both relevant social science literature and the authors’ experiences of carrying out research in Afghanistan and Timor‐Leste. The study demonstrates that the post‐conflict environment moulds research design and, consequently, influences how questions are answered as well as the questions asked. Moreover, it highlights ways to mitigate these issues. This work is of relevance to scholars planning to engage in field research and to researchers reflecting upon their work, as well as to policymakers who are considering undertaking programmes or commissioning research in post‐conflict areas. 相似文献

Effective conservation policies require comprehensive knowledge of biodiversity. However, knowledge shortfalls still remain, hindering possibilities to improve decision making and built such policies. During the last 2 decades, conservationists have made great efforts to allocate resources as efficiently as possible but have rarely considered the idea that if research investments are also strategically allocated, it would likely fill knowledge gaps while simultaneously improving conservation actions. Therefore, prioritizing areas where both conservation and research actions could be conducted becomes a critical endeavor that can further maximize return on investment. We used Zonation, a conservation planning tool and geographical distributions of amphibians, birds, mammals, and reptiles to suggest and compare priority areas for conservation and research of terrestrial vertebrates worldwide. We also evaluated the degree of human disturbance in both types of priority areas by describing the value of the human footprint index within such areas. The spatial concordance between priority conservation and research areas was low: 0.36% of the world's land area. In these areas, we found it would be possible to protect almost half of the currently threatened species and to gather information on nearly 42% of data-deficient (DD) species. We also found that 6199 protected areas worldwide are located in such places, although only 35% of them have strict conservation purposes. Areas of consensus between conservation and research areas represent an opportunity for simultaneously conserving and acquiring knowledge of threatened and DD species of vertebrates. Although the picture is not the most encouraging, joint conservation and research efforts are possible and should be fostered to save vertebrate species from our own ignorance and extinction. 相似文献

Ecological-Economic Modeling for Biodiversity Management: Potential, Pitfalls, and Prospects 总被引:3,自引:0,他引:3

Abstract: Ecologists and economists both use models to help develop strategies for biodiversity management. The practical use of disciplinary models, however, can be limited because ecological models tend not to address the socioeconomic dimension of biodiversity management, whereas economic models tend to neglect the ecological dimension. Given these shortcomings of disciplinary models, there is a necessity to combine ecological and economic knowledge into ecological-economic models. It is insufficient if scientists work separately in their own disciplines and combine their knowledge only when it comes to formulating management recommendations. Such an approach does not capture feedback loops between the ecological and the socioeconomic systems. Furthermore, each discipline poses the management problem in its own way and comes up with its own most appropriate solution. These disciplinary solutions, however, are likely to be so different that a combined solution considering aspects of both disciplines cannot be found. Preconditions for a successful model-based integration of ecology and economics include (1) an in-depth knowledge of the two disciplines, (2) the adequate identification and framing of the problem to be investigated, and (3) a common understanding between economists and ecologists of modeling and scale. To further advance ecological-economic modeling the development of common benchmarks, quality controls, and refereeing standards for ecological-economic models is desirable. 相似文献
