An individual measure of relative survival 总被引:2,自引:0,他引:2

Summary. Relative survival techniques are used to compare survival experience in a study cohort with that expected if background population rates apply. The techniques are especially useful when cause-specific death information is not accurate or not available as they provide a measure of excess mortality in a group of patients with a certain disease. Whereas these methods are based on group comparisons, we present here a transformation approach which instead gives for each individual an outcome measure relative to the appropriate background population. The new outcome measure is easily interpreted and can be analysed by using standard survival analysis techniques. It provides additional information on relative survival and gives new options in regression analysis. For example, one can estimate the proportion of patients who survived longer than a given percentile of the respective general population or compare survival experience of individuals while accounting for the population differences. The regression models for the new outcome measure are different from existing models, thus providing new possibilities in analysing relative survival data. One distinctive feature of our approach is that we adjust for expected survival before modelling. The paper is motivated by a study into the survival of patients after acute myocardial infarction. 相似文献

This study employs interlocking analytical devices from the perspectives of several disciplines to explore members' meanings through definitions of "high technology" given by workers in design engineering. The comparative analysis employs concepts from art history, sociology of culture, anthropology and science studies to explore the appeal of "high technology" in comparison with the aura of original artworks and the status accrued by symbolic tools. Additionally, the role standardization has played in the development of engineering as a profession is explored in historical context as are the recurring themes of speed and "the new." The findings reveal that how engineers use new technologies in the world of messy practice and their conceptual framework regarding so-called "high technology" do not map well onto one another. The study illustrates the perspective of science and technology studies that views all technology as socially shaped and society shaping, its construction accomplished through messy patched-up practices rather than clean, linear paths or perfect techniques. 相似文献

A branch and bound algorithm is presented for determining the minimum number of telephone operators, and their shift schedules, required to meet demand that varies over a 24 hour operating period. An integer linear programming formulation is used, and the algorithm is described in terms of its separation, relaxation, fathoming, and branching procedures. Computational results are provided, using actual operating data. The results indicate that practical sized problems can be solved by the algorithm, involving as many as 100 different shift type variables and demand profiles typical of those encountered in many telephone traffic exchanges. 相似文献

This paper describes a model of reflective supervision for child protection practice that is informed by psychoanalytic theory. Eileen Munro promotes the idea of depth in practice, referring to the skills and knowledge required to undertake the work. Her reports highlight the importance of supervision to provide a thinking space for practitioners where reflection can take place. This paper will explore the importance of supervision in more depth and describe how psychoanalytic ideas can help us understand the complexities of our work with families, anchoring us to a solid theoretical base and helping to make sense of the maelstrom of feelings that are stirred in us as well as in our colleagues and clients. 相似文献

This article takes a first look at the distribution of returns to education for people with disabilities, a particularly disadvantaged group whose labor market performances have not been well studied or documented. Using a nonparametric approach, we uncover significant heterogeneity in the returns to education for these workers, which is drastically masked by conventional parametric methods. Based on these estimates, we construct the Sharpe ratio of human capital investment (taking into account its substantial risk), and our results corroborate the claimed importance of human capital in improving these workers’ wages. Our stochastic dominance tests show that the returns to education for workers with disabilities, as a group, may have been affected more adversely in the most recent recession, relative to their non-disabled counterparts. 相似文献

In this paper the author estimates the compensating variation of income which will be necessary to keep the standard of living of a family constant when a child is born to the family. Various methods of estimation are tried, and an attempt is made to calculate the cost of a child in 1948, after allowances have been made for services provided by the government. 相似文献

Child neglect is a significant concern for Aboriginal families and communities both in Australia and internationally. Service responses to child neglect are largely informed by child neglect theories, which explain the nature and causes of child neglect. However, child neglect is a problem that is worsening for Aboriginal children, suggesting that these theories are not appropriate. This paper argues that to meet the needs of Aboriginal families and communities where there is child neglect, policy and practice needs to acknowledge and address the impact of trauma in shaping the lived experiences of Aboriginal people. International literature discusses the impact and consequence of historical trauma within Indigenous families and communities, and separately, child maltreatment theorists have discussed the ecological nature of child neglect. However, the literature and evidence‐base linking the two, child neglect and historical trauma in Indigenous contexts, are very scant. This paper aims to fill this gap and emphasize the importance of addressing child neglect within Aboriginal families and communities in the context of historical trauma. Although this paper focuses on the post‐colonial experiences of Aboriginal people in Australia, the arguments can extend to many Indigenous cultures universally where child welfare interventions have resulted in significant and ongoing trauma. 相似文献
