Concepts of power and agency have become increasingly prominent in the youth studies literatures and related research. A focus of the research to date has been an examination of how a better understanding of young people's lived experiences can reveal possibilities for young people's agency to emerge. Despite increased interest in the term agency, much less has been said about how the concept is defined and recognized in research with young people, including what the concept may entail but crucially, how the term is linked to and underpinned by the related concept of power. This paper seeks to contribute to our understanding of power and agency as utilized in research with young people. The discussion that follows identifies the possible ways in which different theoretical positions shape our understanding of how power and agency are investigated and how these understandings inform the ways we interpret young people's perspectives and actions as holding potential for ‘agency’. Drawing on recent empirical examples, we consider how varying interpretations of power and/or agency shape not only the ways in which young people's agentic experiences are theorized (and the related ontological and epistemological assumptions these positions imply) but also the presumed effects of that agency. 相似文献

The WHOQOL-BREF is a commonly used questionnaire in quality of life research. Previous research has shown that the four domains of the WHOQOL-BREF (physical health, psychological health, social relationships, and environmental health) are highly related. Whether these high correlations reflected the true relations across the domains or the influence of common method effect; however, is still unknown. This study examines the convergent and discriminant validity of the four domains of the WHOQOL-BREF by using the multitrait-multimethod (MTMM) approach to control the method effect. Two different samples, with a total of 186 and 201 adults, respectively, were used in the present study. Each participant filled out the WHOQOL-BREF questionnaires using four different scaling methods (Likert-type scale, visual analogue scale, pie scale, and partner rating). The covariance matrix of the MTMM result was analyzed with confirmatory factor analysis modeling. Two models were applied, including the correlated traits-correlated uniqueness (CTCU) model and the uncorrelated traits-correlated uniqueness (UTCU) model. Results showed that the CTCU model fit the data better than did the UTCU model, suggesting that the variables tapping the four domains of the WHOQOL-BREF have excellent convergent validity; the four domains have moderate correlations, indicating that the four domains are related but not identical. 相似文献

In Britain, it is recommended that, to stay healthy, adults should do 150 minutes of moderate‐intensity physical activity every week. The recommendations provided by the U.K. government, however, remain silent in regard to the type of activity that should be done. Using the annual Health Survey for England we compare how different types of physical activities predict a person's weight. In particular, we consider clinically measured body mass index and waist circumference. We document mean slopes emanating from ordinary least squares regressions with these measures as the dependent variables. We show that individuals who walk at a brisk or fast pace are more likely to have a lower weight when compared to individuals doing other activities. Additionally, we highlight that the association between physical activity and weight is stronger for females and individuals over the age of 50. Our overall conclusions are robust to a number of specifications. 相似文献

Random samples are assumed for the univariate two-sample problem. Sometimes this assumption may be violated in that an observation in one “sample”, of size m, is from a population different from that yielding the remaining m—1 observations (which are a random sample). Then, the interest is in whether this random sample of size m—1 is from the same population as the other random sample. If such a violation occurs and can be recognized, and also the non-conforming observation can be identified (without imposing conditional effects), then that observation could be removed and a two-sample test applied to the remaining samples. Unfortunately, satisfactory procedures for such a removal do not seem to exist. An alternative approach is to use two-sample tests whose significance levels remain the same when a non-conforming observation occurs, and is removed, as for the case where the samples were both truly random. The equal-tail median test is shown to have this property when the two “samples” are of the same size (and ties do not occur). 相似文献

The second Social Work Summit on End-of-Life and Palliative Care was held from June 1 to June 3, 2005. Sixty representatives of more than 35 social work and other professional organizations with a commitment to improve care for the terminally ill, dying, and bereaved, attended and formulated key priority directions and initiatives that will further the field. 相似文献
