Course Description

Demographers’ interest in mortality has mushroomed over the past several decades. The advent of long time series of mortality data has facilitated research on trends, while major longitudinal surveys have fueled research examining the life course origins of mortality. Population health surveys increasingly include biomarkers of biological risk and physiological dysregulation, facilitating bio-social studies of mortality. The inclusion of genetic data and twin-designs similarly has allowed demographers to probe the causes of mortality by adding a genetic lens. This course will touch on most of these developments, introducing you to major debates and issues that characterize much of mortality research. Necessarily, not all topics will be covered given the time constraints of the semester. The primary focus of the course is on US mortality, often introducing international comparisons and also examining disparities within the US.

Coure Requirements

The course is organized as a seminar. Although I will provide overviews and/or supplemental material in lecture, much instruction takes place in the context of guided discussion and exchanges focused on the readings. Students are expected to attend each class and to have read all of the assigned material thoroughly and critically before the class meeting. Reading critically means not only being able to describe the content of an assigned piece, but also to evaluate the scientific issues motivating the research question, the conceptual/theoretical strengths of the research, the adequacy of the study’s methods, the scientific implications of the study’s findings, and the study’s relation to other course material). Students are strongly encouraged to contribute to the discussion both their insights and/or questions from the readings and their own experiences.

 There are three major tasks to be accomplished in this graduate seminar:

 1) The first task involves preparation of the reading for class presentation and discussion (20% of grade).  All students are responsible for all of the assigned readings. Class discussions will be oriented around informal student presentations based on the assigned readings. For each class meeting, a student will be assigned an article, and the student will informally present the scientific factors motivating a study, the key gaps in knowledge being addressed, the major findings, and the conceptual/methodological strengths and weaknesses of the study.You may use powerpoint if you want. An outline of the presentation’s key points (1 page) should be distributed to the class on the date prior to class. The informal presentations should not be longer than 15 minutes – and 10 minutes is desirable!

2) The second task is an empirical study or a thesis/dissertation proposal on a topic that is relevant to the course’s overall aim (50% of grade). Final papers are due December 12.

• The empirical study may overlap with research being done either as part of a student’s thesis/dissertation research, in conjunction with work being done in another course (with the professor’s permission), or as part of a student’s RA assignment (with the professor’s permission). The study should be original research, with the aims of making a scientific contribution to the literature andpublication in a scientific outlet. Please do not feel constrained by the topics covered in the course. As I mentioned, it is impossible to completely cover the body of mortality research. Given the time constraints imposed by the semester, I recommend that students rely on publicly accessible datasets (e.g., the Health and Retirement Survey, the National Health Interview Surveys, MIDAS, the National Longitudinal Surveys, and Americans’ Changing Lives, and Aging. Other rich datasets are available from NACDA and ICPSR, two major electronic data archives.
• For those pursuing an MA thesis or considering a PhD thesis on mortality, this course offers an opportunity to draft a proposal. This option is not simply a literature review. The proposal should layout specific aims (testable questions/hypotheses), discuss the importance of the work and its contribution to the literature, and provide a discussion of the data to be collected/analyzed and the methods to be used. This should follow the general format of an NIH R03 submission. I will provide the guidelines for the format.
• Regardless of which written option is chosen, students should submit 1-page abstract by October 16. All students should meet with me sometime during October 16-18. Please contact me as soon as possible to set up a time to meet.

3) Powerpoint presentation: I have scheduled presentations for the last class session, December 5(30% of grade). This session will give students a chance to present their work to their colleagues, to field comments, and to refine their ideas and analysis prior to submitting the term paper. Presentations should follow the format that one would use if presenting the results at a major scientific meeting such as the Population Association of America. 

READING LIST

Some readings can be found on Canvas or are accessible via Google Scholar through the UT library. A few readings have hyperlinks to the article.

Description:

This course provides an in-depth introduction to survival methods for the analysis of change in time-dependent discrete dependent variables. The course draws on methodological and empirical research from the social sciences. Special attention is directed at the relationship between theories of social change, life course attainment and dynamic models. Moreover, we will examine alternative data collection strategies to obtain longitudinal data. Examples and homework assignments will draw principally on three data sets: the German Life History Study (GLHS), the National Longitudinal Survey of Older Men, and the National Health Interview Surveys.

The course begins by focusing on simple stochastic processes for qualitative variables. We do sothrough the lens of non-parametric, discrete-time life table techniques. The topics include basiclife table relations, single- and multiple-decrement life table models, and increment-decrementlife table models. The purpose is to learn how to describe increasingly complex dynamic social processes. We then turn to continuous-time, discrete-state models. Parametric and partially parametric models will be introduced which allow for the dependency of rates on both explanatory factors and time. We will briefly examine some special topics including competing risk models, local hazard models, unobserved sources of heterogeneity in hazard models, and continuous state-space hazard models. The purpose of this aspect of the course is to communicate the variety and power of multivariate hazard models for hypothesis testing of dynamic processes in the social sciences.

PREREQUISITES:

Students should have completed the graduate statistics core sequence in sociology (or theequivalent) and have a thorough knowledge of the general linear model. A background in loglinear analysis and logistic regression is important, because hazard models are part of the class of log-linear models. Students must have a solid knowledge of a major spreadsheet package (e.g., EXCEL) for computing and graphing.

REQUIREMENTS:

In addition to reading required materials, attending class sessions, and contributing in class, students must complete three sets of written assignments. First, homework occasionally will be assigned. Homework assignments will involve both numerical problem solving and critical writing. The second written requirement is a final exam. The exam will be a take-home exam involving longitudinal data analysis. The basic aim of the exam is to educate you about how one goes about formulating, estimating, and interpreting event history models. Grades will be based on the final exam (75%) and the homework (25%). I also will evaluate the homework assignments to identify concepts or techniques that are problematic. This year, I am also offering the option of writing an empirical paper using event history techniques in lieu of taking the final exam. If you choose this option, you will need to inform me by October 3rd. I will provide more detailed information about the types of analyses that are required if the paper option is chosen.

READINGS:

The technical literature on survival analysis is voluminous, spanning a variety of fields. For example, partial likelihood hazard models were developed primarily within biostatistics, while the much of the development of parametric hazard models took place within sociology and economics. Starting in the late 1980s, a literature emerged which places these different traditions within a more general survival analysis framework. A major work in this vein is the book, Event History Analysis (Blossfeld, Hamerle, and Mayer, 1989). This text also shows how to estimate hazard models using a variety of software packages (e.g., SAS). More recently Techniques of Event History Modeling was published (Blossfeld and Rohwer, 1995, 2002); this is a comprehensive introduction to continuous-time event history techniques. The 2002 2nd edition is the core text for this course.

The textbook has been ordered by the UT bookstore. The full title is: Blossfeld, Hans-Peter, and Götz Rohwer. 2002. Techniques of Event History Modeling. Second

COURSE CONTENT:

This course is intended to provide an in-depth introduction to the major conceptual frameworks and empirical research examining distal and proximate social factors influencing adult health. The underlying question is – “Does the body forget insults and exposures from adverse social conditions over the life course?” In grappling with this question, we will pay close attention to the intersection between the etiology of adult health conditions and the major life-course trajectories of socioeconomic position and family. Of major importance will be the assessment of key social and biological pathways linking social conditions at particular points in the life course with adult health outcomes.

The course is organized as a seminar. Although I will provide overviews and/or supplemental material in lecture, much instruction takes place in the context of guided discussion and exchanges focused on the readings.

Other rich datasets are available from NACDA and ICPSR, two major electronic data archives. Students are required to discuss their topic with me before moving forward. Students should submit 1-page abstracts. . I will use the abstract to gauge the paper’s topic  relevance to the course aims, and as a basis to provide critical feedback to refine conceptual ideas and focus the analysis.

1) Poster presentation:  These sessions will give students a chance to present their work to their colleagues, to field comments,and to refine their ideas and analysis prior to submitting the term paper. Posters should followthe format that one would use if presenting the results at a major scientific meetings such as the Population Association of America. However, you do not actually need to construct an actualposter. Poster “pages” should be constructed using Powerpoint for presentation to the class.

(30% of grade)

2) Term paper  should aim to be a publishable scientific work suitable for submission to a scientific journal such as Demography. Students should review articles in Demography or other major journals for guidance on presentation styles and organizational format. (50% of grade)
