Prevalence of sufficient physical activity among parents attending a university

OBJECTIVE: The benefits of regular physical activity are well documented. However, approximately half of all university students are insufficiently active, and no research to date exists on the activity behavior of university students who are also parents. PARTICIPANTS AND METHODS: Using an adapted version of the Godin Leisure Time Exercise Questionnaire (ie, the Physical Activity Prevalence Questionnaire), the authors examined the prevalence of sufficient physical activity among 245 parent students from 6 faculties and 12 programs. RESULTS: Half (49.5%) of the students who were not parents (n = 90) were sufficiently physically active, compared with 16% of students who were parents (n = 3, p < .002). The authors found that 33.3% of parents and 13% of nonparents limited their activity level as a result of illness or injury (p < .05). CONCLUSIONS: Most parent students in this study were insufficiently active and at potential risk for the negative health consequences of inactivity. This is a grossly understudied population, and researchers must conduct further studies to understand what can be done to facilitate physical activity among this potentially vulnerable group of students.     

Preference reversals and the measurement of environmental values

Numerous studies have demonstrated that theoretically equivalent measures of preference, such as choices and prices, can lead to systematically different preference orderings, known as preference reversals. Two major causes of preference reversals are the compatibility effect and the prominence effect. The present studies demonstrate that the combined effects of prominence and compatibility lead to predictable preference reversals in settings where improvements in air quality are compared with improvements in consumer commodities by two methods-willingness to pay for each improvement and choice (For which of the two improvements would you pay more? Which improvement is more valuable to you?). Willingness to pay leads to relatively greater preference for improved commodities; choice leads to relatively greater preference for improved air quality. These results extend the domain of preference reversals and pose a challenge to traditional theories of preference. At the applied level, these findings indicate the need to develop new methods for valuing environmental resources.     

Assessing prior information for designed experiments

We examine, via a Bayesian analysis, in a general experimental situation, whether if is worthwhile to obtain additional prior information before performing an experiment. Examples illustrate the application of the techniques developed.     

Into the Dark Heart of Ethnography: The Lived Ethics and Inequality of Intimate Field Relationships

In response to critiques from feminist, existential, and postmodern qualitative researchers, the idea of maintaining objective and distant relationships with research subjects gave way to the belief that researchers could and, in some cases, should become intimately connected to research participants. These traditions opened the door for contemporary field workers to unapologetically forge close relationships to setting members. Several ethical evaluations have emerged from this intimate literature warning researchers of the harm that can come when we “go to far” in the quest for intimate familiarity. In this paper, I reflect on some of the debates regarding intimacy and exploitation by examining my experiences of dating, marrying, and eventually divorcing my key informant. I trace the way that, despite my attempts to follow the existing ethical guides, I reinforced several larger inequalities in my intimate stance. Using my failure to avoid or mitigate harm, I argue that our discussions of intimate methods and immersion in the field have failed to accurately note how we reinforce or resist structure in our research endeavors. Viewing ourselves as “doing structure” in the field would lead us to stop debating whether intimacy is better than objectivity, celibacy is better than sex, disclosure is better than silence, or conventional behavior is better than deviance in the field. Instead, we should locate how our behaviors, research roles, or discursive choices enact structures and the effect this enactment has on the people who we research.
