Title: Extending measurements of change in state space models to understand bivariate time series
Description: A lauded benefit of intensive longitudinal data is in the ability to study change over time. However, with such intensive measurement available, a suitable model or theory regarding just how such changes unfold may be difficult to specify. This problem becomes more salient as the number of measures collected at each time increase. One possible tack is to limit the focus, temporally, in trying to understand change over time. Rather than approach all of the data as informative, instead we may wish to identify windows of time that represent processes of interest. In the data to be presented this approach is taken with two composite daily diary ratings of relationship specific affect. These ratings were collected from heterosexual romantic couples for up to three months. Individual level characteristics as well as follow-up measures of relationship satisfaction and status were also collected from these participants and were used in combination with three geometrically based measures of bivariate change.

Title: TWLITE (Tunable White Light Technology in Elders): Using light therapy in the ORCATECH Life Lab to improve sleep
Description: Recent evidence points to a causal role for poor sleep in the development of pathology in Alzheimer's disease. The TWLITE study, funded by the Hartford Center, is a pilot study to determine whether tunable lamps installed into Life Lab homes can improve sleep, with the ultimate goal of eventually preventing or delaying Alzheimer's.
