Demonstration of a High‐Resolution Passive Profiler for Characterizing the Distribution of PFAS in Groundwater: A Comparison of Methods in the Field

Groundwater Monitoring &Remediation, EarlyView.
Abstract Characterizing the concentration and mass flux spatial distributions at sites with complex hydrogeologic conditions is critical to evaluate the fate and transport of contaminants, as well as to design effective remediation programs. PFAS (per‐ and polyfluoroalkyl substances)‐contaminated sites are even more complex due to the large number of ...

Less Happy, Though More Educated: What Explains Lower Life Satisfaction Among Highly Educated First‐Generation Immigrants in Highly Prosperous Countries?

International Social Science Journal, EarlyView.
ABSTRACT Conventional wisdom suggests that higher education (HE) and national prosperity (or wealth) contribute to improved life satisfaction. Is this also true for first‐generation immigrants? Using multilevel models on 16,368 individuals across 35 European countries from the European Social Survey, the results demonstrate that, although immigrants ...

Reward‐specific learning parameters change across normative adolescent development and are blunted in youth with high risk for depression

Journal of Child Psychology and Psychiatry, EarlyView.
Background Reward learning is thought to undergo refinement in adolescence, but little is known about how computational components of reinforcement learning develop. Given that adolescence is a sensitive period for reward system plasticity with associated vulnerability for depression, it is important to understand developmental trajectories of ...

Optimizing Human Resource Conditions for 20‐Year Initial Public Offering (IPO) Survival

Personnel Psychology, EarlyView.
ABSTRACT The entrepreneurship literature emphasizes the importance of imprints founders leave on companies; those imprints can change at transformational events such as the initial public offering (IPO).
