On July 6, 2013, Montreal, Maine, and Atlantic railcar 5017 hauling 72 tanker cars of Bakken crude oil derailed over the town of Lac‐Mégantic, Quebec. The town erupted in a fiery inferno as 5,560,000 liters of highly flammable Bakken crude oil exploded over the town, killing 47 people and contaminating 558,000 tons of soil and local waterways. While Montreal, Maine, and Atlantic Rail Chairman Edward Burkhardt initially blamed the derailment on the lone engineer and local firefighters, this study shows how Transport Canada and the rail industry undermined regulatory and safety measures for several years before the derailment. This study uses a Foucauldian theoretical perspective to conceptualize and explain a new political mentality that transfers existing state regulatory authority to the corporate sector. This new mentality, neoliberal sovereignty, is composed of sovereign and neoliberal logics that monopolize “correct” trajectories of human economic development. This absolute market mentality merges with state sovereignty and eliminates existing safety and regulation frameworks to pursue unregulated corporate profits. Le 6 juillet 2013, un train de 72 wagons‐citernes transportant du pétrole brute Bakken a déraillé de la ligne de chemin de fer de la Montréal, Maine et Atlantique, dans la ville de Lac‐Mégantic au Québec. La ville c'est transformé en véritable enfer, alors que 5 560 000 litre de pétrole brute Bakken très inflammable ont fait explosé la ville, tuant quarante‐sept personnes et contaminant 558 000 tonnes d'eaux et du sol de Lac‐Mégantic et ses environs. Alors que le président de la MMA, Edward Burkhart, a d'abord blâmé l'ingénieur et le service d'incendie local, les études montrent que Transport Canada et l'industrie ferroviaire ont amoindrit les mesures de réglementation et de sécurité plusieurs années avant le déraillement. Cette étude utilise une perspective théorique foucauldienne pour conceptualiser et expliquer une nouvelle mentalité politique qui transfère l'autorité de régulations gouvernementales existantes au secteur des entreprises. Cette nouvelle mentalité, souveraines et néo‐libérale, est composé de logique souveraines et néo‐libérales qui monopolise les trajectoires « respectables » de développement économique humain. Cette mentalité de marché absolu fusionne avec la souveraineté de l'État et élimine les cadres de sécurité et les réglementations existantes pour les bénéfices des entreprises non réglementaires. 相似文献

David A. Cort 《The International migration review》2012,46(2):483-516
Undocumented immigration has been linked to a wave of anti‐immigrant legislation during the early 1990s. California led the way by passing Proposition 187, which many suspect led legal immigrants to naturalize. No research has confirmed this suspicion. I argue that the years before, during, and after the legislation’s passage and the strength of the labor market represent two contexts of reception in which immigrants reside, which determine naturalization decisions. Event history models show that California’s naturalization rates dramatically increased after the legislation’s passage, a pattern that is most pronounced among Latinos, while rates declined during difficult times, a pattern more pronounced among Asians. Thus, Latinos’ naturalization rates are affected more by the state policy climate, while Asians rates are affected more by long‐term economic health. 相似文献

The ensemble Kalman filter is an ABC algorithm 总被引:1,自引:0,他引:1
The ensemble Kalman filter is the method of choice for many difficult high-dimensional filtering problems in meteorology, oceanography, hydrology and other fields. In this note we show that a common variant of the ensemble Kalman filter is an approximate Bayesian computation (ABC) algorithm. This is of interest for a number of reasons. First, the ensemble Kalman filter is an example of an ABC algorithm that predates the development of ABC algorithms. Second, the ensemble Kalman filter is used for very high-dimensional problems, whereas ABC methods are normally applied only in very low-dimensional problems. Third, recent state of the art extensions of the ensemble Kalman filter can also be understood within the ABC framework. 相似文献

As rural communities undergo substantial demographic and economic changes, understanding the migration intentions and their antecedents of rural elderly persons becomes increasingly important. Using data drawn from a survey of adults from 24 rural Utah communities conducted in 2008, we examine whether rural residents 60 years of age or older plan to remain in their present communities (N= 621). We use structural equation models (SEM) to estimate the relationships between a variety of individual and community-level background measures, including perceptions of local service quality, leaving one's community for health care, Internet use, attachment to and satisfaction with community, and plans to age in place. Results suggest that even as the rural context of economic decline, population loss, and distance to medical services may reduce the viability of staying in a community, a desire to remain in the community is primarily a function of perceptions of the quality of local services and community satisfaction. This research highlights the need to better understand the interplay between the availability of medical services and perceptions of distance as well as to understand the complex relationship between individual and community level characteristics for migration intentions. 相似文献

Despite the significance of relationship management in any information provision or exchange, public relations scholarship has typically focused on examining the underlying internal communication processes from a transactional perspective. These processes are frequently associated with organizational information dissemination, overlooking other critical contents to make strategic decisions. This study draws market information processing into the debate about internal communication, providing a greater understanding of how a relational approach can improve market intelligence dissemination. Results show that an effective management of market knowledge requires the use of such an approach, which in turn, cultivates the shared interpretation of market information and innovation performance. The findings stimulate fresh discussion about the nature and development of internal communication knowledge and practice. 相似文献

The internal conversation has a venerable place in the symbolic interactionist tradition but has been the focus of little empirical research by interactionists. After reviewing selected research on the internal conversation (most by noninteractionist sociologists or nonsociologists), we argue that interactionists ought to conduct research of our own to examine claims we have been making and to better understand social life. We propose some worthy areas and avenues of investigation. 相似文献
