Social norms and human normative psychology

Our primary aim in this paper is to sketch a cognitive evolutionary approach for developing explanations of social change that is anchored on the psychological mechanisms underlying normative cognition and the transmission of social norms. We throw the relevant features of this approach into relief by comparing it with the self-fulfilling social expectations account developed by Bicchieri and colleagues. After describing both accounts, we argue that the two approaches are largely compatible, but that the cognitive evolutionary approach is well- suited to encompass much of the social expectations view, whose focus on a narrow range of norms comes at the expense of the breadth the cognitive evolutionary approach can provide

Identifying biotic determinants of historic American eel (Anguilla rostrata) distributions

Traditionally, ecologists studying large scale patterns in species distributions emphasize abiotic variables over biotic interactions. Noting that both abiotic & biotic variables likely determine distributions of all organisms, many ecologists now aim for a more comprehensive view of species distributions, inclusive of both abiotic and biotic components (Soberón 2007)

FARM LEVEL DYNAMIC ANALYSIS OF SOIL CONSERVATION: AN APPLICATION TO THE PIEDMONT AREA OF VIRGINIA

A conceptual optimal control theory model which considers farm level decision making with respect to soil management is developed. A simplified version of the theoretical model is applied to the Piedmont area of Virginia. The model includes the productivity impacts of both soil erosion and technological progress. Both the theoretical model and its empirical application are improvements over previous efforts. Results suggest that farmers in the study area can achieve substantial reductions in soil erosion by adopting alternative farming practices.Farm Management,

Characterization of Cardiovascular Risk Factors People Living with HIV in a Veteran Population

Background: CVD is the leading cause of death in PLWH. HIV positive individuals have a 1.5-2-fold greater risk of CVD compared to uninfected individuals, even if complete viral load suppression is achieved. HIV-associated CVD has tripled over the past 20 years, yet scant data is available describing this population. We have characterized CVD risk factors and treatment in PLWH in order to assess and improve cardioprotective treatment. Methods: A retrospective EMR review was conducted for HIV positive patients enrolled at the McGuire VAMC between 12/2018 and 12/2019. Patients were excluded if labs were older than one year from follow-up. Patient demographics was collected along with characterization and treatment of their HIV, hypertension, diabetes, and dyslipidemia. Patient CVD status and risk factors were analyzed, and cardioprotective agent appropriateness was assessed. Results: 242 patients were included in this study. Overall, 91% had HIV viral load ≤ 200. 25% of patients had diabetes, of which 51% were controlled. 86% of patients achieved a blood pressure goal of ≤ 140/90. 40% of patients achieved LDL ≤ 70, with 56% of patients on a statin. 14% of patients had past history significant for cardiovascular event. Conclusion: Characterization of CVD in PLWH should be a high priority and treatment should be closely monitored due to the rising disease state burden. Lack of large clinical trials outlining treatment strategies in this aging population has hindered appropriate patient care. Intensified and targeted cardioprotective strategies are needed due to a high proportion of patients with uncontrolled CVD risk factors.https://scholarscompass.vcu.edu/gradposters/1064/thumbnail.jp
