This paper addresses the issue of child protection protocols within research conducted with children. Based partly on primary data this paper raises questions about the role of ethics committees in defining the limits of confidentiality in relation to child protection protocols within research, the perceptions of both children and parents about the meanings of confidentiality and notions of ‘harm’, and the role of the researcher in relation to legal and professional guidance about the protection of vulnerable people in society. We explore the concept of confidentiality within a research setting from a child protection perspective. In doing so we examine the legal and moral obligations of researchers to report child protection concerns, how children themselves perceive ‘harm’, and the need for much clearer guidance to researchers, as well as child participants and parents, about the limitations of confidentiality. 相似文献

This paper is intended to present an introduction to the use of operations research in the international airline industry, and to demonstrate the scope and significance of the airline OR activities. First, the special reasons for the viability and spread of airline OR are discussed. Then a functional framework for an airline is outlined, to be used in analyzing the problems of an airline and relating the OR work to it. Four major applications are described, corresponding to four major components of the framework. These applications are: schedule development, overbooking control, crew scheduling and engine management, respectively. In each case we describe the problem and its significance, indicate the types of solution techniques which have been developed, and assess the implemented solutions. The paper concludes with comments on the current state-of-the-art and the future of airline OR. A detailed bibliography is given.Both of the authors have been operations research directors in major airlines and more recently have focused their attention upon the industry as academic researchers. This background has provided us with an unusual opportunity to analyze the role of OR in the airlines, and our paper seeks to share with the reader some of the insights we have gained thereby. 相似文献

OBJECTIVE: To evaluate the effect of a community-based injury prevention program on work-related injuries. STUDY DESIGN: A population-based quasi-experimental design was used with pre- and post-implementation measurements in an intervention and a control area. The program was based on cross-sectoral participation in detecting and taking action against work-related injuries. Change in the relative risk of injury was estimated by the odds ratio. RESULTS: The relative risk of work-related injury decreased following program exposure, whereas a tendence toward increase was observed in the control area. Middle-aged men accounted for the largest decrease in injury risk. Among the women, a decrease was observed only in the upper middle-aged group. No female-dominated occupational area showed a decrease in injury risk following exposure to the program. CONCLUSION: The study showed that the community-based approach had a general effect on the incidence of work-related injuries. 相似文献

Recent articles by Busza et al. (BJSW) and Dar et al. (DDH) argue that astrophysical data can be used to establish small bounds on the risk of a "killer strangelet" catastrophe scenario in the RHIC and ALICE collider experiments. The case for the safety of the experiments set out by BJSW does not rely solely on these bounds, but on theoretical arguments, which BJSW find sufficiently compelling to firmly exclude any possibility of catastrophe. Nonetheless, DDH and other commentators (initially including BJSW) suggested that these empirical bounds alone do give sufficient reassurance. This seems unsupportable when the bounds are expressed in terms of expectation value-a good measure, according to standard risk analysis arguments. For example, DDH's main bound, p(catastrophe) < 2 x 10(-8), implies only that the expectation value of the number of deaths is bounded by 120; BJSW's most conservative bound implies the expectation value of the number of deaths is bounded by 60,000. This article reappraises the DDH and BJSW risk bounds by comparing risk policy in other areas. For example, it is noted that, even if highly risk-tolerant assumptions are made and no value is placed on the lives of future generations, a catastrophe risk no higher than approximately 10(-15) per year would be required for consistency with established policy for radiation hazard risk minimization. Allowing for risk aversion and for future lives, a respectable case can be made for requiring a bound many orders of magnitude smaller. In summary, the costs of small risks of catastrophe have been significantly underestimated by BJSW (initially), by DDH, and by other commentators. Future policy on catastrophe risks would be more rational, and more deserving of public trust, if acceptable risk bounds were generally agreed upon ahead of time and if serious research on whether those bounds could indeed be guaranteed was carried out well in advance of any hypothetically risky experiment, with the relevant debates involving experts with no stake in the experiments under consideration. 相似文献

Recollection bias (RB) refers to the phenomenon whereby after an adverse event people report that their risk assessment about a similar future event is presently no higher than their recollection of their pre‐event risk assessment. While previous research has outlined this theoretical construct and generated important empirical findings, there were some limitations. We design and employ a new national representative survey to address these limitations in this study. We examine the existence and persistence of RB among the general public in the context of a number of domestic and international terrorist attacks. We further examine the socioeconomic and political base of RB and the influences of RB on a wide range of citizens’ counterterrorism policy preferences. Our data analyses reveal strong evidence showing the occurrence of RB and its persistence across various forms of terrorism risk. With regard to the socioeconomic and political base, we find that females, older people, political conservatives, and Republicans are less likely to be subject to RB. For the effects of RB on public counterterrorism policy preferences, our analyses demonstrate that this bias significantly dampens public support for a wide range of preventive policy measures and government anti‐terrorism spending. Overall, our study, based on a national representative sample and an extended survey design, provides robust evidence of RB in terrorism risk assessment, and adds further evidence to support the idea that RB is likely a generalizable phenomenon. Implications and suggestions for future research are discussed in the conclusion. 相似文献

Public relations as a communication function is emerging as an important organizational process in many parts of the world. This paper examines the development of public relations in a transitional economy: Bosnia-Herzegovina. Data from 38 newly privatized organizations show the perceived potential for public relations as these organizations attempt to communicate with new publics and gain market share in a difficult business environment. The results suggest that Bosnian public relations managers understand public relations as a relationship building function but are constrained from fulfilling this function by the realities of a transitional economy. 相似文献
