Adaptive Appraisals of Anxiety Moderate the Association between Cortisol Reactivity and Performance in Salary Negotiations
Prior research suggests that stress can be harmful in high-stakes contexts such as negotiations. However, few studies actually measure stress physiologically during negotiations, nor do studies offer interventions to combat the potential negative effects of heightened physiological responses in negotiation contexts. In the current research, we offer evidence that the negative effects of cortisol increases on negotiation performance can be reduced through a reappraisal of anxiety manipulation. We experimentally induced adaptive appraisals by randomly assigning 97 male and female participants to receive either instructions to appraise their anxiety as beneficial to the negotiation or no specific instructions on how to appraise the situation. We also measured participants’ cortisol responses prior to and following the negotiation. Results revealed that cortisol increases were positively related to negotiation performance for participants who were told to view anxiety as beneficial, and not detrimental, for negotiation performance (appraisal condition). In contrast, cortisol increases were negatively related to negotiation performance for participants given no instructions on appraising their anxiety (control condition). These findings offer a means through which to combat the potentially deleterious effects of heightened cortisol reactivity on negotiation outcomes

Modification of Weak Localization in Metallic Thin Films Due to the Adsorption of Chiral Molecules
We perform low-temperature magneto-conductance measurementsonCu and Au thin films with adsorbed chiral molecules and investigatetheir phase-coherent transport properties. Upon adsorption of chiralmolecules, the spin-orbit coupling strength in Cu decreasesand the Au films become ferromagnetic as evident from weak localizationand antilocalization data. A theoretical model indicates that anisotropyin the molecular tilt angles, provided that the chiral molecules actas magnetic moments, induces a nonvanishing magnetic exchange interaction,causing changes in the spin-orbit coupling strength in Cu andAu. Our work adds a new viewpoint to the plethora of unique phenomenaemerging from chiral molecule adsorption on materials
Frequent disturbances enhanced the resilience of past human populations
AbstractThe record of past human adaptations provides crucial lessons for guiding responses to crises in the future1–3. To date, there have been no systematic global comparisons of humans’ ability to absorb and recover from disturbances through time4,5. Here we synthesized resilience across a broad sample of prehistoric population time–frequency data, spanning 30,000 years of human history. Cross-sectional and longitudinal analyses of population decline show that frequent disturbances enhance a population’s capacity to resist and recover from later downturns. Land-use patterns are important mediators of the strength of this positive association: farming and herding societies are more vulnerable but also more resilient overall. The results show that important trade-offs exist when adopting new or alternative land-use strategies.</jats:p

Frequent disturbances enhanced the resilience of past human populations.
The record of past human adaptations provides crucial lessons for guiding responses to crises in the future1-3. To date, there have been no systematic global comparisons of humans' ability to absorb and recover from disturbances through time4,5. Here we synthesized resilience across a broad sample of prehistoric population time-frequency data, spanning 30,000 years of human history. Cross-sectional and longitudinal analyses of population decline show that frequent disturbances enhance a population's capacity to resist and recover from later downturns.
