Meta-analysis using multilevel models with an application to the study of class size effects 总被引:1,自引:0,他引:1
Harvey Goldstein Min Yang Rumana Omar Rebecca Turner & Simon Thompson 《Journal of the Royal Statistical Society. Series C, Applied statistics》2000,49(3):399-412
Meta-analysis is formulated as a special case of a multilevel (hierarchical data) model in which the highest level is that of the study and the lowest level that of an observation on an individual respondent. Studies can be combined within a single model where the responses occur at different levels of the data hierarchy and efficient estimates are obtained. An example is given from studies of class sizes and achievement in schools, where study data are available at the aggregate level in terms of overall mean values for classes of different sizes, and also at the student level. 相似文献

This paper contributes to the existing literature by evaluating the effects of age and tenure on careers and productivity within an internal labor market. We use the administrative personnel records of a long balanced panel of blue-collar workers from a manufacturing firm in Germany with a distinct classification of wage groups and unique information on workers’ productivity in form of suggestions for productivity improvement. Using robust locally weighted regression, our main findings suggest that the probability of promotion is highest for younger workers and early in the career. Older workers are less likely to be promoted. The likelihood of making a rewarded suggestion is inversely u-shaped with respect to tenure and age. Furthermore, workers’ ability and firm-specific human capital determine the workers’ careers and productivity. 相似文献

Modelling the effect of pupil mobility on school differences in educational achievement 总被引:1,自引:1,他引:0
Harvey Goldstein Simon Burgess Brendon McConnell 《Journal of the Royal Statistical Society. Series A, (Statistics in Society)》2007,170(4):941-954
Summary. The recently introduced national pupil database in England allows the tracking of every child through the compulsory phases of the state education system. The data from key stage 2 for three local education authorities are studied, following cohorts of pupils through their schooling. The mobility of pupils among schools is studied in detail by using multiple-membership multilevel models that include prior achievement and other predictors and the results are compared with traditional 'value-added' approaches that ignore pupil mobility. The analysis also includes a cross-classification of junior and infant schools attended. The results suggest that some existing conclusions about schooling effects may need to be revised. 相似文献

Natural data on the Australian Human Rights Commission’s website outlining the complaint cases generated from Disability Discrimination Act, 1992 (DDA) were used to examine the social construction of disability employment discrimination. Using a social model and human rights citizenship lens, some 987 complaint cases were analysed to assess the prevalence of disability discrimination in employment, and its relationship to the types of disability, gender, entity undertaking the actions and organisational context. Of all complaint cases across the Australian Human Rights Commission’s operations, by far the largest proportion involves disability discrimination. Within the disability discrimination complaint cases, employment makes up the greatest proportion of these cases. In examining the patterns of discrimination seven major themes emerged involving: distinctive patterns across disability type; access to premises; human resource mismanagement; selection of new employees; integration of assistive technology; perception of cost of disability inclusions; and inflexible organisational workplace practices. The discussion examines the underlying reasons for the emergent themes where employers misunderstood key legal concepts that underpin the DDA including: unjustifiable hardship; inherent requirements; reasonable adjustment; direct; and indirect discrimination. The paper concludes by discussing the implications of the findings as a way of understanding the social construction of disability discrimination in employment to signal ways to better develop inclusive organisational practice. 相似文献
