Topic: research design

Age, calendar period, and birth cohort can be difficult to separate when studying change over time. This workshop introduces approaches to their analysis in longitudinal aging research and explains how research design and data structure affect interpretation. It covers accelerated longitudinal panels, hierarchical age-period-cohort growth models, coordinated analysis across studies, synthesized cohort-sequential designs, and study heterogeneity. Empirical examples connect these methods to practical research questions. Interactive lectures, polls, breakout discussions, and moderated questions s

Methodology for understanding the basic phenomena of life can be done in vitro or in vivo, under tightly-controlled experimental conditions designed to limit variability. However stringent the protocol, these experiments do not occur in a cultural vacuum and they are often subject to the same societal biases as other research disciplines. Many researchers uphold the status quo of biased basic research by not questioning the characteristics of their experimental animals, or the people from whom their tissue samples were collected. This means that our fundamental understanding of life has been b
