Categorizing Risks for Risk Ranking   总被引:3,自引:0,他引:3  
Any practical process of risk ranking must group hazards into a manageable number of categories. Defining such categories requires value choices that can have important implications for the rankings that result. Most risk-management organizations will find it useful to begin defining categories in terms of environmental loadings or initiating events. However, the resulting categories typically need to be modified in light of other considerations. Risk-ranking projects can benefit from considering several alternative categorization strategies and drawing upon elements of each in developing their final categorization of risks. In principle, conducting multiple ranking exercises by using different categorizations could be interesting and useful. In practice, agencies are unlikely to have either the resources or patience to do this, but other groups in society might. Done well, such additional independent rankings could add valuable inputs to democratic risk-management decision making.  相似文献

Despite the increasing popularity of the Ability, Motivation, Opportunity (AMO) framework in the Human Resource Management (HRM) field, AMO research is at a crossroads in theoretical and empirical development. This is due to (a) a lack of clarity about the conceptualisation and measurement of AMO variables, (b) the construction of AMO articles that do not distinguish between AMO differences and AMO-enhancing HRM practices and fail to integrate them, (c) a lack of understanding about how AMO variables at the individual and organizational levels interact to generate individual and organizational performance, and (d) a lack of consideration of the process (mediators and moderators) through which AMO generates performance gains. Based on the analysis of 104 quantitative HRM articles published between 1997 and 2022, this study helps to draw clearer distinctions among AMO variables and levels of analysis. The review of the empirical literature shows that there is excessive heterogeneity with regard to the conceptualization and utilisation of AMO variables, which in turn leads to scale proliferation. We find that research on AMO-enhancing HRM practices and AMO differences is rarely combined and tends to be tested at a single level rather than more logical cross-level effects between AMO-enhancing HRM practices, AMO differences and performance. We also found that whereas Ability and Motivation differences mediate the relationship between AMO-enhancing HRM practices and performance, opportunity appears to be a boundary condition in the relationship between Ability and Motivation with performance outcomes. The paper concludes with relevant avenues for future AMO research suggested for the field of HRM.  相似文献

In this article, drawing on qualitative interviews and documentary analysis, we argue that the Jewish community in Britain has undergone a fundamental shift since 1990 from a 'strategy of security', a strategy of communal leadership based on emphasizing the secure British citizenship and belonging of the UK's Jews, to a 'strategy of insecurity', where the communal leadership instead stresses an excess of security among Anglo-Jewry. We demonstrate this based on two case studies: of the Jewish renewal movement in the 1990s and the 'new antisemitism' phenomenon of the 2000s. We conclude that this shift is tied to the shift from a monocultural Britain to an officially multicultural one, and that therefore there are lessons that can be taken from it for the study of British and other multiculturalisms.  相似文献

The prevalence of pathological gambling among college students is increasing. Few studies have directly examined the relation between reward processing and gambling severity while concurrently examining the effects of co-occurring negative affect in this at risk population. This study used Structural Equation Modeling (SEM) techniques to analyze results from an online survey of 352 female and 96 male students age 18-25. Participants completed measures of past year gambling behavior and severity of gambling problems using the Canadian Problem Gambling Index and the Problem Gambling Severity Index. Negative affect and reward processing were measured by the 21-item version of the Depression, Anxiety, and Stress Scales and the Behavioral Inhibition System and Behavioral Activation System (BIS/BAS) scales, respectively. Thirty-five percent of participants reported gambling in the previous 12 months, and 11% had gambling severity scores indicative of "moderate-risk" or "problem gambling." Gambling severity was associated with negative affect. Negative affect, in turn, was correlated with the unitary BIS scale and inversely associated with the BAS reward responsiveness scale. Reward responsiveness was also inversely associated with gambling severity. In the SEM models, the association between reward responsiveness and gambling severity was mediated by negative affect among males but not among females. Potential explanations for these findings and their implications for addressing problem gambling are discussed.  相似文献

The measurement of walkway slip resistance is required to assess the risk of slipping. Unlike other countries, the U.S. has not decided upon a single approach to the measurement of slip resistance. Several types of tribometers are available to measure slip resistance however, the measured value of the slip resistance of a given surface has been found to be tribometer specific. The introduction of ASTM International Standard F2508 Standard Practice for Validation and Calibration of Walkway Tribometers Using Reference Surfaces, has produced a method which allows validation of each type of tribometer and the values generated during testing.  相似文献
