Environmental migration as short- or long-term differences from a trend: A case study of Hurricanes Katrina and Rita effects on out-migration in the Gulf of Mexico

An environmental event that damages housing and the built environment may result in either a short- or long-term out-migration response, depending on residents' recovery decisions and hazard tolerance. If residents move only in the immediate disaster aftermath, then out-migration will be elevated only in the short-term. However, if disasters increase residents' concerns about future risk, heighten vulnerability, or harm the local economy, then out-migration may be elevated for years after an event. The substantive aim of this research brief is to evaluate hypotheses about short- and long-term out-migration responses to the highly destructive 2005 hurricane season in the Gulf of Mexico. The methodological aim is to demonstrate a difference-in-differences (DID) approach analysing time series data from Gulf Coast counties to compare short- and long-differences in out-migration probabilities in the treatment and control counties. We find a large short-term out-migration response and a smaller sustained increase for the disaster-affected coastal counties.     

Attachment insecurities and under-commitment in distressed couples: The role of positive and negative partner behaviors

Research has rarely considered intermediate variables in the association between attachment insecurities and relationship commitment. Based on attachment theory and Rusbult's Investment Model, we tested whether positive and negative partner behaviors explain this association in 91 distressed couples undergoing therapy. Path analyses based on the Actor–Partner Interdependence Model revealed that individuals with attachment avoidance reported perceiving fewer positive behaviors from their partner, which was associated with their own higher under-commitment. Partners of individuals with avoidance also reported perceiving fewer positive partner behaviors, which was in turn associated with their own higher under-commitment. Partners of individuals with attachment anxiety perceived more positive behaviors from their partner, which was associated to their own lower under-commitment. Perceived negative partner behaviors were only directly associated with higher under-commitment. These findings imply that perceived positive partner behaviors may be a key aspect to target in relationship therapy in couples who present with high attachment insecurities.
