A critical need exists to challenge approaches to nursing home care due to rigid organizational factors and hospital-like culture. It has been argued that resident care needs to move toward a person-centered approach by addressing the organizational, social, and physical environments in nursing home facilities, a process often known as culture change. In response to this need, the Centers for Medicare & Medicaid Services (CMS) has created funding for pay for performance (P4P) nursing home incentive programs to allow nursing home providers to receive CMS reimbursements for culture change in the facilities. Through care staff interviews, site observations, and a document review, this qualitative study assesses the impact of a Midwestern state P4P incentive program in three participating nursing homes. Using an environment and behavior (E-B) policy orientation framework, this study examines culture change through a focus on policy, the physical environment, place attachment, and social and psychological processes in the study settings.  相似文献

An extreme space weather event has the potential to disrupt or damage infrastructure systems and technologies that many societies rely on for economic and social well‐being. Space weather events occur regularly, but extreme events are less frequent, with a small number of historical examples over the last 160 years. During the past decade, published works have (1) examined the physical characteristics of the extreme historical events and (2) discussed the probability or return rate of select extreme geomagnetic disturbances, including the 1859 Carrington event. Here we present initial findings on a unified framework approach to visualize space weather event probability, using a Bayesian model average, in the context of historical extreme events. We present disturbance storm time (Dst ) probability (a proxy for geomagnetic disturbance intensity) across multiple return periods and discuss parameters of interest to policymakers and planners in the context of past extreme space weather events. We discuss the current state of these analyses, their utility to policymakers and planners, the current limitations when compared to other hazards, and several gaps that need to be filled to enhance space weather risk assessments.  相似文献

The use of autonomous underwater vehicles (AUVs) for various applications have grown with maturing technology and improved accessibility. The deployment of AUVs for under-ice marine science research in the Antarctic is one such example. However, a higher risk of AUV loss is present during such endeavors due to the extremities in the Antarctic. A thorough analysis of risks is therefore crucial for formulating effective risk control policies and achieving a lower risk of loss. Existing risk analysis approaches focused predominantly on the technical aspects, as well as identifying static cause and effect relationships in the chain of events leading to AUV loss. Comparatively, the complex interrelationships between risk variables and other aspects of risk such as human errors have received much lesser attention. In this article, a systems-based risk analysis framework facilitated by system dynamics methodology is proposed to overcome existing shortfalls. To demonstrate usefulness of the framework, it is applied on an actual AUV program to examine the occurrence of human error during Antarctic deployment. Simulation of the resultant risk model showed an overall decline in human error incident rate with the increase in experience of the AUV team. Scenario analysis based on the example provided policy recommendations in areas of training, practice runs, recruitment policy, and setting of risk tolerance level. The proposed risk analysis framework is pragmatically useful for risk analysis of future AUV programs to ensure the sustainability of operations, facilitating both better control and monitoring of risk.  相似文献

弱势群体保护问题是当今社会,尤其是公法学界所面临的严峻课题。为了有效应对这一问题,应采用比较研究、实证研究、文献研究的方法,在继续完善传统公法意义上的相关保障性制度的基础上,积极构建弱势群体的社会帮扶制度。弱势群体的社会帮扶制度一方面以服务行政理论为理论依据,要求弱势群体保护由当下的“政治负责”向“社会负责”过渡;另一方面,社会帮扶制度又以公共服务理论为理论支撑,要求政府由高权强制型向怀柔服务型转变。在实践中,弱势群体的社会帮扶制度应遵循政府与社会“两条腿走路”的基本逻辑,而该制度的构建应秉承若干基本思路:破除观念束缚,培育和构建公民社会;丰富社会主体形式,弥补行政保障不足;完善其他社会帮扶途径。  相似文献

Wind power is becoming an increasingly important part of the global energy portfolio, and there is growing interest in developing offshore wind farms in the United States to better utilize this resource. Wind farms have certain environmental benefits, notably near‐zero emissions of greenhouse gases, particulates, and other contaminants of concern. However, there are significant challenges ahead in achieving large‐scale integration of wind power in the United States, particularly offshore wind. Environmental impacts from wind farms are a concern, and these are subject to a number of on‐going studies focused on risks to the environment. However, once a wind farm is built, the farm itself will face a number of risks from a variety of hazards, and managing these risks is critical to the ultimate achievement of long‐term reductions in pollutant emissions from clean energy sources such as wind. No integrated framework currently exists for assessing risks to offshore wind farms in the United States, which poses a challenge for wind farm risk management. In this “Perspective”, we provide an overview of the risks faced by an offshore wind farm, argue that an integrated framework is needed, and give a preliminary starting point for such a framework to illustrate what it might look like. This is not a final framework; substantial work remains. Our intention here is to highlight the research need in this area in the hope of spurring additional research about the risks to wind farms to complement the substantial amount of on‐going research on the risks from wind farms.  相似文献

Participant retention is a key factor in determining the success of longitudinal research. Challenges in re-locating and retaining participants over the long term are major issues for researchers working with young people who face adversity and experience frequent changes in circumstances. This article reports on a study of vulnerable young people and their transition into adulthood. Rather than the more conventional schedule-based approach to locating and re-interviewing young people, a relational process, the ‘right time’ framework, was used to facilitate young people's involvement in the study. Embedded in the ‘right time’ framework is recognition of the diverse and fluctuating circumstances that shape young people's availability for interviews. Several case examples are considered which amplify the way that the ‘right time’ framework allowed the research to navigate around these circumstances. The case examples highlight the value young people attached to being involved in the research, the influence on the ‘right time’ of wider relational tensions for young people and the need to negotiate researcher status as a different sort of adult. The ‘right time’ framework contributed to a high retention rate in the study generating a more representative sample and enhancing the subsequent data analysis by providing valuable insights into the lives of these vulnerable young people.  相似文献

This paper begins by examining the social inclusion agenda that formed the centrepiece of the social policy agenda of the Australian Government between 2007 and 2013. It discusses several features of the agenda, including its objectives (as articulated by the government) and some of the administrative and bureaucratic mechanisms that were put in place to assist with its development and implementation. Although no formal assessment of the impact of the agenda is attempted, some of the ways in which such an agenda could make a difference are identified. The paper then summarises the social inclusion indicator framework developed by the Australian Social Inclusion Unit with assistance and advice from the Australian Social Inclusion Board, and compares its structure and content with the frameworks developed by two of Australia's leading social research institutes. Finally, data from two national surveys of poverty and social exclusion are used to examine recent changes in social exclusion and the association between the severity of exclusion and levels of subjective well‐being. These latter results show clearly that subjective well‐being is consistently lower among those who experience the greatest degree of social exclusion, suggesting that exclusion as identified and measured reflects external constraints rather than internal preferences.  相似文献

The article explores differences in the assessment and decision‐making processes, in child welfare services where a standardized template is implemented and in services where it is not. Child welfare services in several countries use different approaches to assess children's and families' need for intervention. In Norway, as in other European countries, there is a shortage of knowledge about decision‐making strategies. The article examines how 36 child welfare caseworkers in 6 different teams in Norway investigate, assess, and make decisions at the phase of an incoming referral. The analysed data were collected by focus group interviews. We use decision theory as a theoretical frame of reference. The analysis shows variation in the assessment procedure at different points of the process, depending on which approach was used. Despite such differences, the final decisions made were almost identical. Even though the data has its limitations because of the small number of informants, the results indicate that choice of approach is not decisive for decision‐making in the child welfare services.  相似文献

围绕女性主体性视角,聚焦不同属性媒体建构女性农民工形象的话语实践,探讨了新闻文本呈现女性农民工形象的总体特征和社会逻辑。通过对2000—2019年广东省和江苏省4份代表性报纸女性农民工议题新闻报道(N=2485)的内容分析和文本分析,研究发现女性农民工的媒体形象建构呈现出“主体性缺失”和“结构性弱势”两大特点。从报道数量上看,女性农民工议题的重要性经历了高峰过后逐渐下降并趋于平稳的动态变化。较之农民工整体,国内主流报纸对女性农民工“低度再现”。从媒体形象上看,尽管女性农民工行为形象的主观能动性有所提升,但“主体性缺失”的受苦受难者和被关爱者仍占比61.09%,价值形象总体上趋于客观平衡。党政机关报和都市报在女性农民工媒体形象和新闻结构框架上均存在显著性差异,这一差异彰显着形塑文本的社会结构性要素之间的张力。  相似文献
