We tested whether a brief self-affirmation writing intervention protected against identity-threats (i.e., stereotyping and discrimination) for adolescents' school-related adjustment. The longitudinal study followed 639 adolescents in Germany (65% of immigrant descent, 50% female, M-age = 12.35 years, SDage = .69) from 7(th) grade (pre-intervention at T1, five to six months post-intervention at T2) to the end of 8(th) grade (one-year follow-up at T3). We tested for direct and moderated (by heritage group, discrimination, classroom cultural diversity climate) effects using regression and latent change models. The self-affirmation intervention did not promote grades or math competence. However, in the short-term and for adolescents of immigrant descent, the intervention prevented a downward trajectory in mastery reactions to academic challenges for those experiencing greater discrimination. Further, it protected against a decline in behavioral school engagement for those in positive classroom cultural diversity climates. In the long-term and for all adolescents, the intervention lessened an upward trajectory in disruptive behavior. Overall, the self-affirmation intervention benefited some aspects of school-related adjustment for adolescents of immigrant and non-immigrant descent. The intervention context is important, with classroom cultural diversity climate acting as a psychological affordance enhancing affirmation effects. Our study supports the ongoing call for theorizing and empirically testing student and context heterogeneity to better understand for whom and under which conditions this intervention may work.
While the intergovernmental climate regime increasingly recognizes the role of non-state actors in achieving the goals of the Paris Agreement (PA), the normative linkages between the intergovernmental climate regime and the non-state dominated 'transnational partnership governance' remain vague and tentative. A formalized engagement of the intergovernmental climate regime with transnational partnerships can increase the effectiveness of partnerships in delivering on climate mitigation and adaptation, thereby complementing rather than replacing government action. The proposed active engagement with partnerships would include (i) collecting and analyzing information to develop and prioritize areas for transnational and partnership engagement; (ii) defining minimum criteria and procedural requirements to be listed on an enhanced Non-state Actor Zone for Climate Action platform; (iii) actively supporting strategic initiatives; (iv) facilitating market or non-market finance as part of Article 6 PA; and (v) evaluating the effectiveness of partnerships in the context of the enhanced transparency framework (Article 13 PA) and the global stocktake (Article 14 PA). The UNFCCC Secretariat could facilitate engagement and problem solving by actively orchestrating transnational partnerships. Constructing effective implementation partnerships, recording their mitigation and adaptation goals, and holding them accountable may help to move climate talks from rhetoric to action.
The Central Asian Pamir Mountains (Pamirs) are a high-altitude region sensitive to climatic change, with only few paleoclimatic records available. To examine the glacial-interglacial hydrological changes in the region, we analyzed the geochemical parameters of a 31-kyr record from Lake Karakul and performed a set of experiments with climate models to interpret the results. delta D values of terrestrial biomarkers showed insolation-driven trends reflecting major shifts of water vapor sources. For aquatic biomarkers, positive delta D shifts driven by changes in precipitation seasonality were observed at ca. 31-30, 28-26, and 17-14 kyr BP. Multiproxy paleoecological data and modelling results suggest that increased water availability, induced by decreased summer evaporation, triggered higher lake levels during those episodes, possibly synchronous to northern hemispheric rapid climate events. We conclude that seasonal changes in precipitation-evaporation balance significantly influenced the hydrological state of a large waterbody such as Lake Karakul, while annual precipitation amount and inflows remained fairly constant.
