The construct, family resilience, has been defined and applied very differently by those who are primarily clinical practitioners and those who are primarily researchers in the family field. In thisarticle, the family resilience perspective is integrated with conceptual definitions from family stress theory using the Family Adjustment and Adaptation Response (FAAR) Model in an effort to clarify distinctions between family resiliency as capacity and family resilience as a process. The family resilience process is discussed in terms of (a) the meaning of significant risk exposure (vs. the normal challenges of family life) and (b) the importance of making conceptual and operational distinctions between family system outcomes and family protective processes. Recommendations for future family resilience research are discussed.  相似文献

A sample size justification should be given for all clinical investigations. However, sometimes the objective of a trial is to estimate an effect with a view to planning a later definitive study. This paper describes the calculations for designing studies where one wishes to adopt an estimation approach through using confidence intervals around the overall response. Calculations are given for data anticipated to take a Normal form. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

How social movements use art is an understudied question in the social movements literature. Ethnographic research on the use of art by the prodemocracy movement in Pinochet's Chile suggests that art plays a very important role in social movements, which use it for framing, to attract resources, to communicate information about themselves, to foster useful emotions, and as a symbol (for communicating a coherent identity, marking membership, and cementing commitment to the movement).  相似文献

This paper discusses the value of action learning for social work supervisors. Recent years have seen renewed focus on supervision as a reflective space and some indications that the tide may be turning in regard to the dominance of managerial priorities within the supervision of direct practice. It is less evident that a similar shift is taking place for supervisors themselves and, anecdotally, many describe their own supervision as having a business focus with limited scope for reflective dialogue. While the traditional functions of supervision need to adapt to fit the responsibilities of those in management positions, it remains true that these staff provide a vital containing role within the organisational hierarchy. For that to be sustained, it is important that supervisors have space and structure within which to process the emotional, intellectual and practical challenges of their work. The integration of action learning sets within post-qualifying courses for supervisors has demonstrated a useful dual function. Firstly, they provide an effective model for group supervision, facilitating in-depth reflection on complex practice issues. Secondly, they offer managers a peer supervision forum; a safe place to explore dilemmas and share the vulnerabilities which belong to management roles as well as practice.  相似文献

As part of a comprehensive environmental health strategic planning project initiated by the government of Abu Dhabi, we assessed potential dietary exposure in the United Arab Emirates (UAE) to methylmercury (in seafood) and pesticides (in fruits and vegetables) above international guideline levels. We present results for the UAE population by age, gender, and body mass index. Our results show very low daily risks of exposure to pesticides in fruits and vegetables at levels exceeding WHO guidelines even under the conservative assumption that no pesticides are removed during washing and food preparation. Thus, exposure to pesticides on fruits and vegetables does not appear to be a major public health concern in the UAE. The chances of exposure to methylmercury in seafood are much higher; our model estimates a mean 1 in 5 daily risk of exceeding the FAO/WHO provisional tolerable weekly intake. However, great caution should be used in interpreting these results, as we analyzed only the risks and not the substantial benefits of fish consumption. In fact, previous studies have demonstrated that exposure to the n‐3 polyunsaturated fatty acids in fish can increase IQ in developing children, and it can substantially decrease the risk in adults of coronary heart disease and stroke. Further research is warranted to compare the risk of Me‐Hg exposure from fish to the nutritional benefits of fish consumption in the UAE and to determine appropriate methods to communicate risk and benefit information to the UAE population.  相似文献
