Recent medical sociological research has examined whether the relationship between education and health is dynamic across age, whereas recent demographic research has examined whether the relationship varies across cohorts. In this study, I examine how cohort structures the influence of education on life-course health trajectories. At the cohort level,(More)
This paper investigates the joint effects of academic self-efficacy and stress on the academic performance of 107 nontraditional, largely immigrant and minority, college freshmen at a large urban commuter institution. We developed a survey instrument to measure the level of academic self-efficacy and perceived stress associated with 27 college-related(More)
Sociologists often describe culture as a repertoire of shared understandings. But because the meanings that social actors attribute to symbols and actions emerge from the multiple associations they make between them, delineating collectively shared understandings is not a straightforward task. Standard quantitative sociological practice, which relies on the(More)
OBJECTIVE Research has increasingly focused on the dynamic nature of disability and depressive symptoms in later life. Little research, however, has modeled disability and depressive symptoms as dynamic, related processes. Furthermore, virtually no research has considered social support as dynamic across age. Here, we investigate the relationship between(More)
The existence, nature, and strength of race differences in mental health remain unclear after several decades of research. In this research, we examine black-white differences in the relationship between acute stressors and depressive symptoms. We reframe the stress exposure and differential vulnerability hypotheses in the context of long-term trajectories(More)
In this research we develop a model of mortality rates that parameterizes mortality deceleration and compression, permits hypothesis tests for change in these parameters over time, and allows for formal gender comparisons. Our model fits mortality data well across all adult ages 20-105 for 1968-1992 U.S. white data, and the results offer some confirmation(More)
This paper uses data from the Fragile Families and Child Wellbeing Study to test the hypotheses that (1) Similar to other positive pre- and post-natal outcomes, Mexican immigrant mothers are more likely to breastfeed, and to breastfeed longer, than white or Mexican-American mothers; and (2) Acculturation accounts for the ethnic/nativity differential in(More)
Researchers have attempted to explain the relationship between education and health by incorporating mediators-such as income--through which schooling affects health. Research has also shown that the education-health relationship varies across age and cohort. This article integrates these themes in an investigation of the role income plays in the changing(More)
An Internet router was integrated into the UK-DMC remote-sensing satellite as a secondary experimental payload. This commercial product has been orbiting in space for over three years. We describe the integration of the router and satellite and the successful on-orbit testing of the router, which took place using the Virtual Mission Operations Center (VMOC)(More)
