The Whites Writing Whiteness project is concerned with changes to the racial order in South Africa over a long time-period and connects ‘big numbers’ and work on very large archive collections with close textual analysis of particular documents. It uses longitudinal data within a Qualitative Longitudinal Research methodological approach, combining formal analysis with a sampling process. In operationalizing this, letters from the Findlay Family collection with thousands of documents, a group of around 190 letters by Elizabeth Price, and a small set of Gottlob Schreiner’s letters, are discussed. In doing so, useful conceptual and methodological tools for analysing other large longitudinal datasets are provided. 相似文献

This study reports the findings of interviews with fifty socialworkers who volunteered to describe their personal experiencesof depression in the workplace. The findings confirm the literatureon the stresses of social work and provide an account of theways in which the social workers sought to reconcile their mentalhealth needs with their role as professionals. The study suggeststhe potential for those working at all levels in social workagencies to support social workers who are experiencing depression.At a time of shortages in the profession in the UK, and of effortsto enable those with mental health problems to remain in orreturn to work, the experiences of those social workers interviewedillustrate the managerial, training and human resource imperativesto provide more supportive workplaces. 相似文献

A California Environmental Protection Agency (Cal/EPA) report concluded that a reasonable and likely explanation for the increased lung cancer rates in numerous epidemiological studies is a causal association between diesel exhaust exposure and lung cancer. A version of the present analysis, based on a retrospective study of a U.S. railroad worker cohort, provided the Cal/EPA report with some of its estimates of lung cancer risk associated with diesel exhaust. The individual data for that cohort study furnish information on age, employment, and mortality for 56,000 workers over 22 years. Related studies provide information on exposure concentrations. Other analyses of the original cohort data reported finding no relation between measures of diesel exhaust and lung cancer mortality, while a Health Effects Institute report found the data unsuitable for quantitative risk assessment. None of those three works used multistage models, which this article uses in finding a likely quantitative, positive relations between lung cancer and diesel exhaust. A seven-stage model that has the last or next-to-last stage sensitive to diesel exhaust provides best estimates of increase in annual mortality rate due to each unit of concentration, for bracketing assumptions on exposure. Using relative increases of risk and multiplying by the background lung cancer mortality rates for California, the 95% upper confidence limit of the 70-year unit risks for lung cancer is estimated to be in the range 2.1 x 10(-4) (microg/m3)(-1) to 5.5 x 10(-4) (microg/m3)(-1). These risks constitute the low end of those in the Cal/EPA report and are below those reported by previous investigators whose estimates were positive using human data. 相似文献

马克思主义哲学的世界性就在于它远远跨越了民族界限、国家界限 ,而成为无与伦比的世界性哲学 ,它在具体表现一个民族的思维特征的同时克服了民族思维的狭隘性 ,因而趋向为带有鲜明共性的世界性思维。马克思主义哲学的中国化正是马克思主义世界性的具体表现。 相似文献
