Models for the assessment of the risk of complex engineering systems are affected by uncertainties due to the randomness of several phenomena involved and the incomplete knowledge about some of the characteristics of the system. The objective of this article is to provide operative guidelines to handle some conceptual and technical issues related to the treatment of uncertainty in risk assessment for engineering practice. In particular, the following issues are addressed: (1) quantitative modeling and representation of uncertainty coherently with the information available on the system of interest; (2) propagation of the uncertainty from the input(s) to the output(s) of the system model; (3) (Bayesian) updating as new information on the system becomes available; and (4) modeling and representation of dependences among the input variables and parameters of the system model. Different approaches and methods are recommended for efficiently tackling each of issues (1)?(4) above; the tools considered are derived from both classical probability theory as well as alternative, nonfully probabilistic uncertainty representation frameworks (e.g., possibility theory). The recommendations drawn are supported by the results obtained in illustrative applications of literature. 相似文献

The public inquiry into paediatric cardiac surgery at the Bristol Royal Infirmary commissioned the authors to design and conduct analyses of routine data sources to compare surgical outcomes between centres. Such analyses are necessarily complex in this context but were further hampered by the inherent inconsistencies and mediocre quality of the various sources of data. Three levels of analysis of increasing sophistication were carried out. The reasonable consistency of the results arising from different sources of data, together with a number of sensitivity analyses, led us to conclude that there had been excess mortality in Bristol in open heart operations on children under 1 year of age. We consider criticisms of our analysis and discuss the role of statisticians in this inquiry and their contribution to the final report of the inquiry. The potential statistical role in future programmes for monitoring clinical performance is highlighted. 相似文献

The issue of cross‐border migration in South‐East and East Asia is linked to the integration of regional, if not global, labour markets. The types of labour that are currently in demand have changed substantially since the 1990s in terms of (1) overall magnitude, (2) gender composition, and (3) increased diversification. This paper, however, focuses upon those workers classified as unskilled as they constitute numerically the largest and most vulnerable group. The challenges to provide adequate protection from, and prevention of, exploitative and abusive practices that seriously minimize the socio‐economic benefits for these workers are linked to migration policies and the issue of rights in the origin and destination countries. This paper's objective is to provide a broad outline of the emerging trends and issues revolving around contemporary cross‐border labour migration and the politics of migrants' rights in South‐East and East Asia, illustrated by the difficulties experienced with the ratification of the 1990 United Nations Convention on the Rights of All Migrants and their Families (ICMR). The data this paper is based upon were collected for a report commissioned by the United Nations Educational, Scientific and Cultural Organization (UNESCO) with fieldwork carried out in seven countries located in the Asia Pacific region. It is argued that ratification of the ICMR is obstructed by politics and by a lack of political will. A rights‐based approach to the protection of migrant labour is thus related to a number of macro and micro level issues, revolving around development and practices of “good governance” in addition to interstate relations. This means that the promotion of migrants' rights requires a holistic approach addressing national and transnational issues in an era of increasing mobility across borders. 相似文献

Uncle Sam's loyal nieces have come a long way from the days of World War I. The development of occupational and physical therapy was heavily influenced by an early relationship with medical specialists during the First World War. This relationship can be considered largely responsible for the eventual acceptance (by the Armed Forces) of women working in this area. Over the past decade active duty women have seen many changes in opportunities to serve and are now stationed aboard aircraft carriers, performing roles previously considered for male personnel. We report a case study of the medical care provided by both military and civilian women working for the United States Armed Forces. Initial assessment was conducted in a battalion aid station of a United States Marine Corp base and the subject was then referred to a military medical center with highly technical vestibular assessment and rehabilitation services. The subject's case represents a unique collaboration of women therapists, enabling a Marines' access to timely and accurate assessment, treatment and ultimately, successful return to active duty. This case study is one of many examples of the acceptance and successful integration of women as providers of medical care within the Military's medical framework. 相似文献

Independent Living: gender, violence and the threat of violence 总被引:2,自引:2,他引:0
In what ways is independent living for young adults with disabilities compromised by violence and its threat? A qualitative study of 42 young adults with severe physical disabilities explored their perceptions and concerns about independent living, access to services and the meeting of needs. Young women especially experienced difficulties about leaving home, because of their own and their parents' fears about vulnerability; some who did leave home experienced highly restricted social lives because of anxiety about neighbourhood violence. Few had established partnerships, but violence and sexual abuse from partners emerged as an issue for which there is little policy. Control and abuse within caring relationships are serious issues for those who need personal care. Violence and lack of protection may undermine independent living, especially for women. 相似文献

This paper questions the extent to which New Zealand children have benefited from New Right economic policies and argues that the invisibility of children, the role of public concern about children and the social construction of childhood are factors which have facilitated implementation of these changes. Attention is drawn to the ways in which the personal and the political spheres intersect in children's lives. Rather than focusing on either the micro level of intervention in the lives of individual children or the macro level of societal change it is argued that the dualism itself must be transcended in order to move forward from the current position.

Feedback is indispensable and ubiquitary. Giving constructive feedback is an important aspect of leadership. Giving good feedback is, however, rather difficult, and one often observes that employees feel hurt and demotivated by the way feedback is given. A central aspect of good feedback relates to maintaining, enhancing, or impairing people's self-esteem, and the present article focuses on this aspect. We discuss the implications of feedback for self-esteem, criteria for optimal feedback, and the difficulties of giving and accepting feedback, especially when it is negative. The last part discusses feedback in the context of performance appraisal in organizations. 相似文献

This article critically examines the utility of the ‘global care chain’ concept and considers various modifications required to that concept in order to render it a major generative force in feminist and non-feminist research. By way of progressing this research agenda, the discussion critically evaluates the possibilities and limitations of a more rigorous application of global commodity chain analysis, from which the global care chain concept is presently only loosely derived, to transnational care services. The incompatibility of (non-feminist) commodity chain analysis and (feminist) care chain analysis, together with the weaknesses in each of these bodies of analysis, requires the integration of a range of modifications into a revised global care chain framework. These modifications involve foregrounding transnational labour networks and applying an engendered global commodity chain perspective to the analysis of these networks as well as broadening the application of the global care chain concept to embrace a variety of groups and settings. Further research required to progress the development of this field of study is outlined. 相似文献

ABSTRACTTechnological advancements, a changing demography, and labour market demands mean that it is increasingly important to have a skilled Māori labour workforce. Māori students are graduating from universities in increasing numbers but little is known about their careers post-graduation. Our aim was to describe the early career aspirations and destinations of Māori university graduates in the Graduate Longitudinal Study New Zealand. Data were collected when participants were in their final year of study (n?=?626) and 2 years post-graduation (n?=?455). The most common occupation types 2 years post-graduation were professionals (66%), clerical or administrative workers (10%), and managers (9%). The most common industries of employment were education and training (29%), health care and social assistance (22%), and legal and accounting services (8%). The percentage of graduates who, in their final year of study, planned to enter into industries that matched their actual industries at 2 years post-graduation was 67%. There were some differences across fields of study, with Health and Education graduates working in industries more closely aligned with their studies than Science or Humanities graduates. Future surveys will enable us to track graduates to see if these patterns change as graduates settle into their careers post-graduation. 相似文献
