Collaborative Registered Replication of Griskevicius et al. (2010) : Can Pro-environmental Behavior Be Promoted by Priming Status Motivation?
(2025-09-15) Lazarevic, Ljiljana B.; Wagge, Jordan R.; Balci, Busra Bahar; Buchanan, Erin M.; Greene, Nathaniel R.; Folwarczny, Michał; Lazić, Aleksandra; Want, Stephen C.; Lee, Seungyeon; Raddatz, Megan C.; Hehman, Eric; Gentile, Adriana; Petrović, Marija B.; De Luca, Paul; Kelly, Andrew J.; Talbot, Karine; Tobia, Jessica; Chalik, Lisa; Tsoi, Lily; Florence, Joey H.; Weissgerber, Sophia C.; Schouler, Niklas; Buron, Laurianne; Christopherson, Cody D.; Richter, Johanna; Senftner, Karina; Pazda, Adam D.; Allen, Peter J.; Kingston, Francesca; Sigurdsson, Valdimar; Grahe, Jon; Department of Business and Economics
The present study presents the results of a collaborative registered replication of Griskevicius et al. (2010, Experiment 1). As part of the Collaborative Replication and Education Project, 24 student groups from six countries (N = 3,774) investigated whether pro-environmental behavior can be promoted by priming status motives (desires for social status and prestige). This large, multi-site replication showed no evidence to support the hypothesis that hypothetical pro-environmental behavior can be stimulated by having participants read a story designed to prime status motives. We performed several exploratory analyses to investigate whether extension variables (i.e., equating “green” choices with prosocial behavior, political beliefs, sampling methods, location, duration of data collection, and gender) moderated the hypothesized effect of status motives on pro-environmental choices, but these analyses produced null results. One limitation of the study is that most data collection sites did not include a manipulation check, and the one site that did found a much weaker effect (d = 0.32) than the extremely large effect originally reported (d = 3.69). As a result, it remains unclear whether the null result reflects a failure of this specific priming method or a challenge to the underlying theory.
Climate Vulnerability and Firms’ Default Risk : The Moderating Role of Country-Level Corruption
(2026-01-01) García-Gómez, Conrado Diego; Demir, Ender; Díez-Esteban, José María; Lizarzaburu Bolaños, Edmundo; Department of Business and Economics
This paper examines the relationship between a country’s climate vulnerability and corporate default risk, utilizing a sample of 2,483 firms across 33 European countries. We find that higher country-level climate vulnerability (as measured by the ND-Gain index) is associated with an increased corporate default risk, as measured by the z-score. In addition, we identify that country-level corruption exacerbates the negative impact of climate vulnerability on corporate financial stability. Even firms with strong financial positions face heightened default risks, highlighting the pervasive threat of climate change. Corruption exacerbates this risk by undermining environmental governance, distorting resource allocation, and weakening climate adaptation strategies. Our results remain robust when considering alternative measures of climate vulnerability and default risk, varying model specifications, and addressing endogeneity using instrumental variables. This study emphasizes the critical interplay between climate vulnerability, governance, and corporate resilience, offering insights for policymakers and practitioners alike.
Characterizing the heterogeneity of neurodegenerative diseases through EEG normative modeling
(2025-12) Tabbal, Judie; Ebadi, Aida; Mheich, Ahmad; Kabbara, Aya; Güntekin, Bahar; Yener, Görsev; Paban, Veronique; Gschwandtner, Ute; Fuhr, Peter; Verin, Marc; Babiloni, Claudio; Allouch, Sahar; Hassan, Mahmoud
Neurodegenerative diseases like Parkinson’s (PD) and Alzheimer’s (AD) exhibit considerable heterogeneity of functional brain features within patients, complicating diagnosis and treatment. Here, we use electroencephalography (EEG) and normative modeling to investigate neurophysiological mechanisms underpinning this heterogeneity. Resting-state EEG data from 14 clinical units included healthy adults (n = 499) and patients with PD (n = 237) and AD (n = 197), aged over 40. Spectral and source connectivity analyses provided features for normative modeling, revealing significant, frequency-dependent EEG deviations with high heterogeneity in PD and AD. Around 30% of patients exhibited spectral deviations, while ~80% showed functional source connectivity deviations. Notably, the spatial overlap of deviant features did not exceed 60% for spectral and 25% for connectivity analysis. Furthermore, patient-specific deviations correlated with clinical measures, with greater deviations linked to worse UPDRS for PD (⍴ = 0.24, p = 0.025) and MMSE for AD (⍴ = −0.26, p = 0.01). These results suggest that EEG deviations could enrich individualized clinical assessment in Precision Neurology.
Characterising acute and chronic care needs : insights from the Global Burden of Disease Study 2019
(2025-12) GBD 2019 Acute and Chronic Care Collaborators; Department of Psychology
Chronic care manages long-term, progressive conditions, while acute care addresses short-term conditions. Chronic conditions increasingly strain health systems, which are often unprepared for these demands. This study examines the burden of conditions requiring acute versus chronic care, including sequelae. Conditions and sequelae from the Global Burden of Diseases Study 2019 were classified into acute or chronic care categories. Data were analysed by age, sex, and socio-demographic index, presenting total numbers and contributions to burden metrics such as Disability-Adjusted Life Years (DALYs), Years Lived with Disability (YLD), and Years of Life Lost (YLL). Approximately 68% of DALYs were attributed to chronic care, while 27% were due to acute care. Chronic care needs increased with age, representing 86% of YLDs and 71% of YLLs, and accounting for 93% of YLDs from sequelae. These findings highlight that chronic care needs far exceed acute care needs globally, necessitating health systems to adapt accordingly.
Caffeine, Daytime Sleepiness, and Conduct Problems Among Early Adolescents : A Longitudinal Analysis
(2025-05) Kogan, Steven M.; Lilly, Christa L.; James, Jack E.; Kristjansson, Alfgeir L.; Department of Psychology
Purpose: Recent research suggests that caffeine use may promote a range of adjustment difficulties among adolescents, particularly during the middle school years. The effects of caffeine are particularly concerning given the increased use of high-dosage caffeine products, such as energy drinks, among youth. We investigated the influence of caffeine use on trajectories of conduct problems among early adolescents. Daytime sleepiness was tested as mediator of caffeine's effect. Methods: Hypotheses were tested with longitudinal (4 waves) data from 2,633 middle school students beginning in the Fall of sixth grade and concluding in the spring of seventh grade. All students in a single class cohort at 20 West Virginia middle schools were invited to participate. Results: Controlling for family affluence and management practices and pubertal development, use of more than 100 mg of caffeine significantly predicted linear increases in conduct problems over time (Est. = 0.23, p = .015). Increases in daytime sleepiness partially mediated this effect (Est. = 0.22, p = .002). Discussion: Caffeine use and daytime sleepiness are important vulnerability factors for the emergence of conduct problems.
