The development of analytical and interpretational protocols to facilitate the provenance establishment of polycarbonate headlamp lens material

Despite the forensic significance of polycarbonate headlamp lenses, robust analytical protocols to facilitate their discrimination are scarce. In this study, laser ablation inductively coupled plasma mass spectrometry has been applied to the analysis of polycarbonate headlamp lenses with multivariate chemometrics techniques utilized to facilitate interpretation of the data. The analytical protocol involves the analysis of 46 analytes on material comprising the exterior surface of the lens. Using this data, it was found that although minor variation exists within a single headlamp lens, discrimination between lenses produced from a single manufacturing plant was still possible using iterative forward stepwise linear discriminant analysis processes. Discrimination between all headlamp lenses, with the exception of some lenses produced on the same day in a single plant, could be achieved using the analytical protocol. Furthermore, an interpretational protocol has been developed that has successfully classified all tested headlamp lens samples, within the discrimination limits of the analytical method.     

Testing the Moderating Effect of Parent–Adolescent Communication on the Acculturation Gap–Distress Relation in Korean American Families

Although the acculturation gap generally has been associated with poor mental health outcomes among Asian American children, some studies have failed to find a significant relationship between the gap and distress. Using two different methods of operationalizing the gap between mothers and their children, the current study addressed this tension in the literature by testing the following hypotheses in a sample of Korean American families. It was hypothesized that mother–adolescent discrepancies in acculturation and enculturation levels would be associated with youth internalizing and externalizing symptoms and that parent–adolescent communication would moderate the gap–distress relationship. Multi-informant questionnaires were administered to 77 Korean American mother–adolescent dyads from the Midwest. Surprisingly, results indicated that consonance in low levels of mother–adolescent enculturation was associated with the highest levels of externalizing symptoms (interaction term method). Adolescents’ perception of communication with their fathers significantly moderated the relationship between the enculturation gap and internalizing symptoms, such that in dyads with a greater enculturation gap, less perceived open communication with fathers was associated with more internalizing symptoms (difference score method). Clinically, the findings indicate a potential target (i.e., parent–adolescent communication) for treatment programs that aim to improve family relations and youth adjustment in immigrant families.     

Stay or exit: How do international nongovernmental organizations respond to institutional pressures under authoritarianism?

International nongovernmental organizations (INGOs) are increasingly important players in global politics and development. However, they are undergoing significant adaptations as governments worldwide have instituted restrictions to regulate their activities. What explains the various ways in which they respond to these institutional pressures? In our study of INGO responses to a new restrictive law in China, we identify four strategic responses with varying levels of compliance: legal registration, provisional strategy, localization, and exit. The institutional pressures—strategic responses link is influenced by INGOs' adaptive capacity, which is in turn shaped by an organization's issue sensitivity, value-add, government ties, and reputational authority. The integrated framework we develop for INGO strategic responses can shed light on state-INGO relations in other countries, many of which are subject to increasingly stringent regulations and a closing political environment.
