Alcohol consumption and related problems are common among college students. Prior research links behavioral economic (BE) constructs of alcohol demand and relative reinforcement (RR), and alcohol expectancies, with alcohol consumption/problems. However, research has yet to examine the associations between BE, expectancy theory, and alcohol use outcomes. In this study, college students (= 287) completed a single online survey assessing demand, RR, alcohol expectancies, and alcohol use/problems. We examined the cross-sectional indirect association of expectancies and drinking on the relationship between demand and alcohol problems and between RR and alcohol problems. The final model showed adequate fit, χ(26) = 67.23, RMSEA = .07, CFI = .95, SRMR = .06. Higher demand and RR were associated with stronger alcohol expectancies, which demonstrated an indirect association on the relationship between demand, and RR, and alcohol problems. Findings suggest that demand and RR may be directly related to alcohol expectancies; a relationship that has not been previously identified. Moreover, alcohol expectancies may impact the associations among demand, RR, and alcohol problems. Thus, alcohol expectancies may be an important intervention target for reducing alcohol problems. Future longitudinal research is needed to evaluate this association over time and assess if these findings have potential impact for intervention research.

The development of plant-based meat substitutes is imperative for reducing animal fat intake and promoting dietary diversification. However, the flavor profiles of these products frequently fall short of consumer expectations. This study sought to optimize the production process of meat flavorings for plant-based products using the Taguchi method.

Background: We aimed to identify the central lifestyle, the most impactful among lifestyle factor clusters; the central health outcome, the most impactful among health outcome clusters; and the bridge lifestyle, the most strongly connected to health outcome clusters, across 29 countries to optimise resource allocation for local holistic health improvements.
Methods: From July 2020 to August 2021, we surveyed 16 461 adults across 29 countries who self-reported changes in 18 lifestyle factors and 13 health outcomes due to the pandemic. Three networks were generated by network analysis for each country: lifestyle, health outcome, and bridge networks.

Background: There is consistent evidence for the contribution of modifiable risk factors to dementia risk, offering opportunities for primary prevention. Yet, most individuals are unaware of these opportunities.
Objective: To investigate whether online education about dementia risk reduction may be a low-level means to increase knowledge and support self-management of modifiable dementia risk factors.
Unveiling the enzymatic pathway of UMG-SP2 urethanase: insights into polyurethane degradation at the atomic level.

The recently discovered metagenomic urethanases UMG-SP1, UMG-SP2, and UMG-SP3 have emerged as promising tools to establish a bio-based recycling approach for polyurethane (PU) waste. These enzymes are capable of hydrolyzing urethane bonds in low molecular weight dicarbamates as well as in thermoplastic PU and the amide bond in polyamide employing a Ser-Ser -Lys triad for catalysis, similar to members of the amidase signature protein superfamily. Understanding the catalytic mechanism of these urethanases is crucial for enhancing their enzymatic activity and improving PU bio-recycling processes.

Many witnesses are intoxicated at crime scenes, yet little is known of their ability to accurately describe perpetrators to police. We therefore explored the impact of alcohol on delayed verbal face recall across two experiments. Participants were administered an alcoholic or non-alcoholic beverage prior to viewing either one or two unfamiliar female faces, which they described from memory the following day while in a sober state.
