College Friendships

Drawing from Turning Point Theory, this study explores whether context shifts, which are changes in the location where a friendship is enacted, affect relationship trajectories and friendship closeness. Study 1A ( N = 120) experimentally manipulated invitations for context shifts in college friendships to test their effects on perceived relationship trajectory, social attraction, and closeness. Study 1B ( N = 112) replicated the results of Study 1A with working adults. Both studies’ results suggest that context-variable shifts lead to a change in perceived relationship trajectory but did not influence social attraction or closeness. In Study 2, first-year students ( N = 98) reported on turning points in their friendships twice over 9 weeks. Friendships reporting context-variable shifts as a turning point were associated with higher friendship closeness than relationships that had no turning points and similar closeness as friendships that reported self-disclosure as a turning point.

Abstract A Fourier method is used to model mountain waves that have nearby turning points in a wind jet. In Fourier space, the propagation equations are solved by ray theory. To correct for the ray singularity at a turning point without time-consuming special-function evaluations, the ray solution is linearly interpolated across the breakdown region. The Fourier solutions for the spatial wavefield are compared with mesoscale model simulations in two cases: two-dimensional flow over idealized topography with uniform stratification and a sech-squared wind profile and three-dimensional flow over the island of Jan Mayen with stratification and wind profiles taken from radiosonde measurements. The latter case reveals the partial transmission of trapped mountain waves into the stratosphere.
