Doctoral Dissertation Research: The Social Composition of Occupations

这项研究关注的是描述和解释职业的社会构成的变化。 它使用了一个基于生态竞争理论的模型。 利基重叠-各职业之间共有的社会人口特征-预计会产生竞争压力，导致一个职业的基本利基发生变化。 该模型使用来自当前人口调查年度人口档案的数据进行测试。 %%% 这项研究将有助于从社会学的角度理解为什么职业的构成会因年龄、性别、种族和类似特征而变化，以及为什么职业的构成会随着时间的推移而变化。 这一信息对致力于鼓励职业多样性的决策者应有所帮助。 除了通过研究取得的科学成果外，该奖项还将在物质上帮助一位非常有前途的学生完成博士研究。论文 因此，它有助于国家未来的科学人才和下一代社会科学家的全面培训。 这项研究关注的是描述和解释职业的社会构成的变化。 它使用了一个基于生态竞争理论的模型。 利基重叠-各职业之间共有的社会人口特征-预计会产生竞争压力，导致一个职业的基本利基发生变化。 该模型使用来自当前人口调查年度人口档案的数据进行测试。 %%% 这项研究将有助于从社会学的角度理解为什么职业的构成会因年龄、性别、种族和类似特征而变化，以及为什么职业的构成会随着时间的推移而变化。 这一信息对致力于鼓励职业多样性的决策者应有所帮助。 除了通过研究取得的科学成果外，该奖项还将在物质上帮助一位非常有前途的学生完成博士研究。论文 因此，它有助于国家未来的科学人才和下一代社会科学家的全面培训。

This research is concerned with describing and accounting for changes in the social compositon of occupations. It uses a model based on an ecological theory of competition. Niche overlap--shared sociodemographic characteristics among occupations--is expected to create competitive pressures that lead to changes in an occupation's basic niche. The model is tested using data from the Current Population Survey Annual Demographic Files. %%% This research will contribute to sociological understanding of why occupations vary in composition according to age, gender, race, and similar characteristics and why occupations change their compositon over time. This information should be of help to policy makers concerned with efforts to encourage occupational diversity. In addition to the scientific gains to be achieved by the research, this award will materially assist a highly promising student in completing research for the Ph.D. dissertation. Thus it contributes to the future scientific manpower of the nation and the thorough training of the next generation of social scientists.
