The aim of this paper is to highlight how ergonomics contributes to risk analysis and risk management in a design project for a new reactor, the French EPR (European Pressurized Reactor). An iterative ergonomics design process has been conducted over the last 10 years through a Human Factors Engineering program at the French energy company EDF. A parallel has been drawn between a risk management process and this ergonomics process based on International Organization for Standardization (ISO) publications such as ISO/IEC Guide 73, ISO Guide 51, etc. The contribution of ergonomics to risk analysis is illustrated by an example: the automatic diagnosis, which is a very important technical device for safety. Five main types of risk have been identified via ergonomic analyses during the different design stages. Counter-measures have been implemented and their efficacy tested within the scope of new campaigns to assess human factors. However, the management of risks in such a design project requires the participation both of the different design entities involved in the project and of other experts in aspects of risk management, such as human reliability. The organization of collaborative participation remains a challenge to be addressed. 相似文献

In January 2004, the National Collaboration for Youth approved a list of core competencies needed by entry-level youth development workers for effective youth development practice. This chapter provides an overview of these competencies, explaining why and how the list was created, outcomes, and recommendations for next steps. 相似文献

A comparative analysis of public sector restructuring in the U.S., Canada, Mexico, and the Caribbean
We examine public sector restructuring in North America and selected Commonwealth Caribbean nations. Although all the countries
studied experienced significant restruc-turing in response to public debt pressures, there were major differences across coun-tries
in the magnitude, pace, form, and the manner in which restructuring decisions were made. These differences reflect the state
of economic development and institu-tional characteristics, e.g., the role of the state and the industrial relations system.
In developing countries, international lending institutions played a major role in trans-forming the role of the state. In
developed countries, the inherent stability of the eco-nomic systems and institutional pressures led to a gradualist approach
to restructuring. 相似文献

Electrophysiological work in nonhuman primates has established the existence of multiple types of signals in the temporal lobe that contribute to recognition memory, including information regarding a stimulus’s relative novelty, familiarity, and recency of occurrence. We used high‐density event‐related potentials (ERPs) to examine whether young infants represent these distinct types of information about previously experienced items. Twenty‐four different highly familiar and initially novel items were each repeated exactly once either immediately ( Experiment 1 ), or following one intervening item ( Experiment 2 ). A late slow wave (LSW) component of the ERP exhibited neural responses consistent with recency signals over right‐central leads, but only when there were no intervening stimuli between repetitions. The LSW also exhibited responses consistent with familiarity signals over anterior‐temporal leads, but only when there were intervening stimuli between repetitions. A mid‐latency negative component (i.e., the Nc) also distinguished familiar from novel items, but did not exhibit a pattern of responding consistent with familiarity signals. These findings suggest that infants encode information about a variety of objects from their natural environments into long‐term memory, and can discriminate between familiar and unfamiliar items, and between recently seen and new items, very quickly (within 1 sec). They also suggest that infants represent information about not only whether a stimulus is familiar or unfamiliar but also whether it has been seen recently. 相似文献

This inquiry focuses on the attitudes of 314 Mexican Americans toward issues relating to current US immigration policy. Telephone and personal interviews were conducted in Hidalgo and Travis counties, Texas, with Mexican-Americans. Virtually all respondent groups oppose an increased rate of immigration, consider illegal immigration to be an important problem, support stricter enforcement of immigration laws, and believe that undocumented workers take jobs no one else wants. Half of the respondents identify illegal immigration as a regional rather than a personal problem. At the same time, the data suggest significant differences in both direction and intensity of attitudes between Mexican Americans of different generations, income, occupational levels, and region. There is general opposition to the requirement of a national identity card, but widespread support for penalizing employers of undocumented workers and for granting amnesty to undocumented workers. These findings allow an examination of the extent to which the Mexican American leadership, which has been overwhelmingly opposed to the Simpson-Mazzoli bill, accurately reflects the views of the Mexican American people. The leadership and the population at large agree on 2 of the 3 issues, amnesty and the national identity card, but disagree on employer sanctions. 1st, it may be that the leadership holds the kinds of jobs for which undocumented workers are unlikely to compete, so they may not feel threatened. 2nd, they may feel that instituting employer sanctions will create incentives for employers to discriminate in their hiring practices against all Latino-looking job applicants. Non-elite Mexican Americans who support employer sanctions may believe that the only way they can compete for jobs is to make it impossible for elites to be hired. Both groups appear to fear that, regardless of the specifics of immigration reform, Mexican Americans are likely to encounter increased discrimination in the job market. 相似文献

Many of the cost functions associated with depot location algorithms assume an overall demand for a fixed period, usually one year. This paper describes an investigation into the effect of high seasonality within such demand figures on the optimal location of storage facilities. The preliminary results indicate that a more flexible approach for certain products could be worthwhile. 相似文献

This article draws on constructivist theories of identity that regard the self as coming into existence through interaction with the other. It investigates the discursive formation of Indigenous people in the forging of Mexican national identity. The aim of this article is to show how difference has been managed and deployed in the establishment of national Mexican identities from independence until the present. This is done with reference to visual culture and film and illustrated with examples from the ‘Golden Age’ as well as ‘the New Mexican Cinema’. 相似文献
