Extreme and catastrophic events pose challenges for normative models of risk management decision making. They invite development of new methods and principles to complement existing normative decision and risk analysis. Because such events are rare, it is difficult to learn about them from experience. They can prompt both too little concern before the fact, and too much after. Emotionally charged and vivid outcomes promote probability neglect and distort risk perceptions. Aversion to acting on uncertain probabilities saps precautionary action; moral hazard distorts incentives to take care; imperfect learning and social adaptation (e.g., herd‐following, group‐think) complicate forecasting and coordination of individual behaviors and undermine prediction, preparation, and insurance of catastrophic events. Such difficulties raise substantial challenges for normative decision theories prescribing how catastrophe risks should be managed. This article summarizes challenges for catastrophic hazards with uncertain or unpredictable frequencies and severities, hard‐to‐envision and incompletely described decision alternatives and consequences, and individual responses that influence each other. Conceptual models and examples clarify where and why new methods are needed to complement traditional normative decision theories for individuals and groups. For example, prospective and retrospective preferences for risk management alternatives may conflict; procedures for combining individual beliefs or preferences can produce collective decisions that no one favors; and individual choices or behaviors in preparing for possible disasters may have no equilibrium. Recent ideas for building “disaster‐resilient” communities can complement traditional normative decision theories, helping to meet the practical need for better ways to manage risks of extreme and catastrophic events.  相似文献

Little attention has been devoted in the past to the in-depth training of clinical supervisors, although they play a pivotal role in the professional development of social workers. To address this learning gap, the Smith College School for Social Work inaugurated the Advanced Clinical Supervision Certificate Program in 2005, as part of its continuing education series. This article addresses a unique feature of the training program: a 9-month “winter practicum” of online case presentations and group discussions that follows the participants' week together on the Smith campus. The author, the practicum facilitator, describes the adjustment of the group to interactions that are not face-to-face. Themes and dynamics emerge as in any other supervisory group. The author concludes that real relationships can be fostered and maintained in cyberspace, particularly when a connection among group members has already been established through prior in-person contact.  相似文献

哈贝马斯(Habermas)是当代西方具有影响力的批判理论家,其对修辞学的贡献在于将归属于批判理论的交往重要性进行理论化。他对各种形式的公共性的历史叙述,尤其是18世纪的公共领域的叙述,以及他对交往行为理论的阐述,构成了他对20世纪修辞学理论所作的贡献。本文拟从修辞学的角度探讨哈贝马斯的批判理论,以便从一个全新的视角对他的理论进行解读。  相似文献

The Victorian Child Death Review Committee (VCDRC) in Australia is a multidisciplinary Ministerial Advisory Committee established to review the deaths of children either currently child protection clients or known to the statutory child protection system. The Committee provides advice about each child death as well as insights into what are the surrounding patterns and issues. Key to this role is examining the contribution of the service sectors to the protection of children and the routine practices that are in place to respond to children and vulnerability. This paper provides a snapshot of the cases referred to the VCDRC and the key messages for practice drawn from them. What emerges is that often the threshold for when statutory child protection services must be involved in child and family matters can be ambiguous and that agreement about intervention, the level and nature of need or risk, and when cumulative harm and neglect require statutory responses are not always shared between agencies. It is clear that the lack of common frameworks about what constitutes child protection intervention challenges services. It is recommended that there be and used agreed definitions and frameworks to ensure shared understandings and collaborative responses across the service and legal systems.  相似文献

Logic models (LMs) have been used in programme evaluation for over four decades. Current debate questions the ability of logic modelling techniques to incorporate contextual factors into logic models. We share experience of developing a logic model within an ongoing realist evaluation which assesses the extent to which, and under what circumstances a community health workers (CHW) programme promotes access to maternity services in Nigeria. The article contributes to logic modelling debate by: i) reflecting on how other scholars captured context during LM development in theory-driven evaluations; and ii) explaining how we explored context during logic model development for realist evaluation of the CHW programme in Nigeria. Data collection methods that informed our logic model development included documents review, email discussions and teleconferences with programme stakeholders and a technical workshop with researchers to clarify programme goals and untangle relationships among programme elements. One of the most important findings is that, rather than being an end in itself, logic model development is an essential step for identifying initial hypotheses for tentative relevant contexts, mechanisms and outcomes (CMOs) and CMO configurations of how programmes produce change. The logic model also informed development of a methodology handbook that is guiding verification and consolidation of underlying programme theories.  相似文献

Agency theory suggests that when agencies adopt flexible work schedules, employees will be more likely to remain with the organization, because these programs demonstrate that the organization cares about their well-being in that flexible work schedules give them more flexibility regarding when, where, and how they perform their work. To test this proposition, cross-sectional panel data at the agency level were obtained from two federal government sources: Federal Employee Viewpoint Survey and FedScope. Furthermore, transfers and quits were the two forms of turnover examined. After lagging the independent variables behind turnover over several years so as to provide a robust test of causality, the results show only limited support for agency theory. Specifically, teleworking was found to lower quits. However, teleworking was not found to reduce transfers or turnover, in general. Furthermore, alternative work schedules were not found to have an impact on quits, transfers, or turnover generally.  相似文献

The complex ways in which food security actions lead to nutrition and other health outcomes make it important to clarify what programs work and how, with theory-driven evaluation emerging as a promising approach to evaluate complex programs. However, it is unclear how and why theory-driven evaluation is applied in food security contexts. Our objective is to examine the development and use of Theory of Change and Realist Evaluation to support food security programs globally. Using a systematic search and screening process, we included studies that described a food security program, used a Theory of Change or Realist Evaluation, and presented original research or evaluations. We found a total of 59 relevant Theory of Change studies and eight Realist Evaluation studies. Based on our analysis, Theories of Change arose in response to three main problems: 1) the need to evaluate under complexity; 2) challenges with evaluation; and, 3) information gaps surrounding a program. In contrast, Realist Evaluation was reported to be developed primarily to understand a program’s outcomes. Reflecting on the problem to be addressed in the evaluation would help improve understandings of the evaluation context, which would then inform the choice and design of an evaluation approach.  相似文献

By applying the supplies-values (S-V) fit approach from the complementary person-environment (P-E) fit literature to the leader-employee perspective, and drawing upon social exchange theory, we examine how fulfillment of different work values is related to Leader-Member Exchange (LMX) and work outcomes. First, polynomial regression analyses combined with response surface analysis of data collected at two time points (N = 316) showed that LMX (Time 2) was higher the more the leader fulfills the employee's work values (Time 1). Second, LMX (Time 2) was higher when leader supplies (Time 1) and employee work values (Time 1) were both high than when both were low. Third, analyses of data from a sub-sample of matched leader-employee dyads (N = 140), showed that LMX (Time 2) played a mediating role on the relation between S-V fit (Time 1) and work outcomes (Time 2). Specifically, we found eight out of 10 relationships between S-V fit (Time 1) and leader-rated task performance and OCB (Time 2) to be fully mediated by LMX (Time 2). LMX (Time 2) partially mediated the relation between S-V fit (Time 1) and job satisfaction (Time 2) as only two out of five relationships were fully mediated.  相似文献
