Insights will be combined from the preceding theory course SASR1 (Sociological theory construction and model building), SASR2 (Family and social inequality), and the course SaSR3: Methods and Statistics course 1. Students will do so by writing a research paper in the format of a journal article: they choose a relevant research question, study the literature and formulate a theoretical answer, analyze data, and report on their findings. A complex dataset (European Sustainable Workforce Survey) - allowing answers to a considerable number of research questions - will be made available to the students. The European Sustainable Workforce Survey is a multi-actor dataset in which information is gathered from firms and employees in 9 European countries. During the first week, students will work on the research question the introduction of the paper, and get acquainted with the dataset. In the second week, the theory section is written, and preliminary analyses are performed. In the subsequent two weeks, the students will further analyze the data, report the results and write the conclusion. During the course, students will work in groups on their paper using theEuropean Sustainable Workforce Survey and meet the teacher several times per week. In the fourth week students will present their (provisional) results to the other students and discuss each other's work. Using the insights and remarks of the other students, they will finish their paper.
