This article presents a discourse on the incorporation of organizational factors into probabilistic risk assessment (PRA)/probabilistic safety assessment (PSA), a topic of debate since the 1980s that has spurred discussions among industry, regulatory agencies, and the research community. The main contributions of this article include (1) identifying the four key open questions associated with this topic; (2) framing ongoing debates by considering differing perspectives around each question; (3) offering a categorical review of existing studies on this topic to justify the selection of each question and to analyze the challenges related to each perspective; and (4) highlighting the directions of research required to reach a final resolution for each question. The four key questions are: (I) How significant is the contribution of organizational factors to accidents and incidents? (II) How critical, with respect to improving risk assessment, is the explicit incorporation of organizational factors into PRA? (III) What theoretical bases are needed for explicit incorporation of organizational factors into PRA? (IV) What methodological bases are needed for the explicit incorporation of organizational factors into PRA? Questions I and II mainly analyze PRA literature from the nuclear domain. For Questions III and IV, a broader review and categorization is conducted of those existing cross-disciplinary studies that have evaluated the effects of organizational factors on safety (not solely PRA-based) to shed more light on future research needs. 相似文献

The article examines types of role strategies utilized by police to gain control over perceived oppositional group activity. Literature in the area of formal organizations and police structures are viewed as deficient in terms of examining the combined effect of presenting multiple images of an organization to an oppositional group. Boundary-spanning roles are conceptualized as varying in terms of discretion, penetration and secrecy. Data from the 1976 Republican Convention are used to identify four types of boundary-spanning roles utilized to gain control over demonstrator activity. While each of these roles served an important control function, in combination the roles presented an inconsistent and contradictory image of the police to demonstrators. The effect of this strategy was to create confusion in the strategies and tactics of the oppositional group.Partial support for this research was obtained through an L.E.A.A. grant, Evaluation of the 1976 Republican National Convention, awarded to Midwest Research Institute (MRI). Patricia E. Erickson and James Flynn were employed as consultants to MRI for the grant period. Special thanks are extended to Bruce B. Morgan who served as project director. 相似文献

This is the first in an occasional series of DPR Debates, designed to illuminate specific issues of international development policy. Each debate will bring together two well‐known researchers or practitioners, giving them the opportunity, over three rounds, to test and challenge each other's ideas. The debates are intended to be robust but accessible, rooted in rigorous research but useful to the wide readership of Development Policy Review. 相似文献

This study examines whether shift-and-persist coping, a coping strategy defined by accepting challenges and remaining hopeful for the future, is associated with psychosocial and physical health and/or moderates the effects of contextual stress (i.e., racial discrimination, financial strain) on health among African American adolescents living in the rural Southeastern United States. Participants (N = 299, 56% boys, Mage = 12.91) completed measures of shift-and-persist coping, contextual stress, and psychosocial and physical health. Shift-and-persist coping was generally associated with better health but did not buffer the effects of contextual stress. Results suggest that shift-and-persist coping may serve as a source of resilience among African American adolescents living in a context where many experience heightened contextual stress. 相似文献

Crystal methamphetamine (aka "crystal meth") use with high-risk sex has become an emerging health problem for gay and bisexual men in New York City since the late 1990s. Public health campaigns were eventually developed to encourage gay and bisexual men to avoid or reconsider using crystal meth. Reactions to three campaigns were measured with a cross-sectional survey administered in 2004. Among an ethnically-diverse sample of 971 gay and bisexual men, 61.8% reported seeing the campaigns. Those who reported ever using crystal meth, recent use, and recent use with sex were significantly more likely to have seen the campaigns. In general, white men, HIV-negative men, and men not currently using crystal meth responded more positively to the campaigns than their counterparts; yet, more men of color reported having discussions with partners and friends about their crystal use as a result of these campaigns. Implications for researchers and practitioners are discussed. 相似文献

This article uses the theory of uneven and combined development (U&CD) to produce a novel explanation of ‘Brexit and Trump’ – the two shock political events of 2016. The argument proceeds in three steps. First, we identify the global conjuncture of historical unevenness in which the votes occurred: how the neoliberal transformation of the advanced capitalist countries was synchronized with the radically different process of primitive accumulation in China. Second, we apply the theory of U&CD to this peculiar ‘simultaneity of the non‐simultaneous’: the ‘big country’ effects of China's industrialization, we find, were thrice multiplied by its combination with the advanced sectors of the world economy, which accelerated China's take‐off, brought forward its export phase, and widened its export profile at a moment of maximum openness in international trade. Finally, this produced the pattern of development that led to the events of 2016: the resultant trade shocks intensified the internal inequalities of British and American societies in ways that match the geography of the Leave and Trump votes. The analysis has a wider intellectual implication too, for the phenomena of historical unevenness and combination are intrinsic to the history of the global political economy; and the theory of U&CD therefore has a unique contribution to make to the field of International Political Economy. 相似文献
