Economic theory as political philosophy

I defend the integrity of the question of what the cognitive status of economic theory could amount to, and I argue that the theory is best understood as a compartment of formal political philosophy, in particular a species of contractarianism. This seems particularly apt as an account of general equilibrium theory. Given the intentional character of the explanatory variables of economic theory and the role of information in effecting choice, it is argued that economic theory is unlikely to secure the predictive power that would enable it to function as a factual instead of a normative theory.     

Promoting walking among older adults living in retirement communities

The authors tested the feasibility and acceptability, and explored the outcomes, of 2 walking interventions based on ecological models among older adults living in retirement communities. An enhanced intervention (EI) was compared with a standard walking intervention (SI) among residents in 4 retirement facilities (N = 87 at baseline; mean age = 84.1 yr). All participants received a walking intervention including pedometers, printed materials, and biweekly group sessions. EI participants also received phone counseling and environmental-awareness components. Measures included pedometer step counts, activities of daily living, environment-related variables, physical function, depression, cognitive function, satisfaction, and adherence. Results indicated improvements among the total sample for step counts, neighborhood barriers, cognitive function, and satisfaction with walking opportunities. Satisfaction and adherence were high. Both walking interventions were feasible to implement among facility-dwelling older adults. Future studies can build on this multilevel approach.     

Quantifying the magnitude and potential influence of missing data in campus sexual assault surveys: A systematic review of surveys, 2010–2016

Objective: To understand how missing data may influence conclusions drawn from campus sexual assault surveys. Methods: We systematically reviewed 40 surveys from 2010–2016. We constructed a pseudo-population of the total population targeted across schools, creating records proportional to the respective response rate and reported sexual assault prevalence. We simulated the effects of 9 scenarios where the sexual assault prevalence among nonresponders differed from that of responders. Results: The surveys represented a total female undergraduate population of 317,387 with only 77,966 (24.6%) survey responses. Among responders, 20.4% reported experiences of sexual assault. However, prevalence of sexual assault could theoretically range from 5.0 to 80.4% under extreme assumptions about prevalence in nonresponders. Smaller, but still significant differences were observed with less extreme assumptions. Conclusions: Missing data are widespread in campus sexual assault surveys. Conclusions drawn from these incomplete data are highly sensitive to assumptions about the sexual assault prevalence among nonresponders.     

'The Justice of Queen Victoria': Boer Oppression,and the Emergence of a National Identity in Lesotho

The growth of a national identity in Lesotho after 1910 was a direct response to the threat of incorporation into the Union of South Africa. The Basotho feared being governed by what they considered to be an unjust and hostile South Africa. The Basotho appealed to the justice of the British government - for them to continue to honour the protection that they had extended to the nineteenth-century Basotho chief, Moshoeshoe. The protection which Moshoeshoe had secured entrenched his position as the centrepiece of the Basotho's emergent national identity in the twentieth century.     

Assessing University Students’ Self-efficacy to Employ Alcohol-Related Harm Reduction Strategies

Abstract

Objective: Develop and evaluate key psychometric properties of a self-report questionnaire specifically designed to assess student drinkers’ self-confidence to employ a variety of strategies intended to reduce unhealthy consequences of high-risk drinking. Methods: Four hundred ninety-eight participants rated their confidence (from “not at all confident” to “completely confident”) to employ 17 harm reduction strategies when drinking. Results: Factor analysis and internal consistency reliability analyses indicated that the 17 items constitute a single scale with good test–retest reliability. Consistent with other research examining previous use of such strategies, women in our sample reported significantly higher harm reduction self-efficacy than did men. Harm reduction self-efficacy was also associated with reported number of high-risk drinking episodes in the previous 2 weeks. Conclusion: This brief and easily administered questionnaire holds promise as a clinical tool to identify individuals with low harm reduction self-efficacy and as an outcome measure for health promotion and educational interventions.
