Role of health-promoting behaviours for on-campus and distance education students

University students are likely to experience high rates of stress, which has the potential to negatively affect academic performance and their experience of study. Research with on-campus students has found positive benefits of health-promoting behaviours such as stress reduction and academic achievement; yet no research has examined these relationships with distance education students (and in comparison with on-campus students). Distance education students are a growing cohort in Australia higher education and elsewhere. This paper aims to redress this imbalance by comparing the relationships between stress, strain and coping, academic outcomes, and health-promoting behaviours in tertiary students (on-campus and distance education students). The study involved 242 on-campus and 399 distance education students at a regional Australian university. A path model was developed comparing both cohorts, and relationships were found to be similar, indicating no significant difference. Online interventions for distance education students which could be used to enhance coping are discussed.     

Organisational change: a solution-focused approach

This study investigates the effectiveness of a solution-focused approach to organisational change. Planning Alternative Tomorrows with Hope (PATH) is an intervention more commonly applied to individuals. In this study the intervention is used with groups of people working in educational organisations to help manage the change process. The approach allows group members to plan a way forward to manage change. Semi-structured interviews took place with six education officers involved in the interventions. The design of the research study follows an interpretative case-study model, and uses content analysis to identify key factors. Findings show the importance of PATH acting as a catalyst for change, giving a sense of immediacy, and allowing participants to shape their own future. For change to be sustained and be successful it cannot occur in isolation. Based on the conclusions of the research study, a number of issues for professional practice are discussed and considered.     

“Vulnerability” in AIDS-affected states: Rethinking child rights,educational institutions,and development paradigms

The article interrogates current international development constructs of childhood, rights, vulnerability, and schooling in light of the daily experiences of two Malawian children affected by HIV/AIDS. It aims to better understand how development efforts targeted at these children function in practice, and suggests that current development discourses and frameworks may sometimes operate to make the lives of vulnerable children and communities harder and less secure. New frameworks for international HIV/AIDS development programming are needed that conceptualize the child and community as part of global educational, social, political, and economic systems that can fuel inequality as well as improve life experiences.     

Dyscalculia and Typical Math Achievement Are Associated With Individual Differences in Number-Specific Executive Function

Deficits in numerical magnitude perception characterize the mathematics learning disability developmental dyscalculia (DD), but recent studies suggest the relation stems from inhibitory control demands from incongruent visual cues in the nonsymbolic number comparison task. This study investigated the relation among magnitude perception during differing congruency conditions, executive function, and mathematics achievement measured longitudinally in children (n = 448) from ages 4 to 13. This relation was investigated across achievement groups and as it related to mathematics across the full range of achievement. Only performance on incongruent trials related to achievement. Findings indicate that executive function in a numerical context, beyond magnitude perception or executive function in a non-numerical context, relates to DD and mathematics across a wide range of achievement.     

An empirical analysis of political activity in Hollywood

Film plays an important role in the American political system, and forms an important branch of the mass media. I analyze the political contributions of a sample of 996 top film actors, directors, producers, and writers, correlating them with demographic, family, and career success variables. I find that contributions flow overwhelmingly to left-of-center parties and organizations. I theorize about the causes of this bias, and argue empirically that, while demographic variables are not completely irrelevant, Hollywood liberalism is primarily a function of high, publicly visible incomes, and family connections. Neither religion nor birthplace effects seem to affect political activity in the film business.

The relationships between self-assessed habitual physical activity and non-invasive measures of cardiac autonomic modulation in young healthy volunteers

Heart rate variability estimates cardiac autonomic modulation, but the relationship between habitual physical activity and heart rate variability remains unclear. The aims of this study were to compare RR-interval and heart rate variability indices in individuals of different habitual physical activity levels, and examine the relationship between habitual physical activity and heart rate variability. Ninety-two healthy volunteers (47 men, 45 women; mean age 23.1 years, s = 2.1) were divided into tertiles according to the Baecke Questionnaire score. Standard heart rate variability indices were derived from 5-min resting RR-interval recordings with paced respiration (0.25 Hz). Between-group differences and the relationship between habitual physical activity and heart rate variability were assessed. More active participants (tertiles 2-3) had longer RR-intervals than those in tertile 1 (P < 0.05). Participants in tertile 2 had higher root mean squared differences of successive normal RR-intervals than those in tertile 1 and a higher standard deviation of normal RR-intervals than those in tertiles 1 and 3. There was a positive linear relationship between habitual activity and RR-interval. Differing RR-interval lengths were found in subgroups of young individuals according to level of habitual physical activity. More active individuals showed resting bradycardia without evidence of enhanced cardiac parasympathetic modulation. The mechanism linking habitual physical activity and RR-interval length appears to be independent of physiological mechanisms that can be measured by heart rate variability.     

Validity of wearable activity monitors for tracking steps and estimating energy expenditure during a graded maximal treadmill test

The purpose of this study was to assess the accuracy of energy expenditure (EE) estimation and step tracking abilities of six activity monitors (AMs) in relation to indirect calorimetry and hand counted steps and assess the accuracy of the AMs between high and low fit individuals in order to assess the impact of exercise intensity. Fifty participants wore the Basis watch, Fitbit Flex, Polar FT7, Jawbone, Omron pedometer, and Actigraph during a maximal graded treadmill test. Correlations, intra-class correlations, and t-tests determined accuracy and agreement between AMs and criterions. The results indicate that the Omron, Fitbit, and Actigraph were accurate for measuring steps while the Basis and Jawbone significantly underestimated steps. All AMs were significantly correlated with indirect calorimetry, however, no devices showed agreement (p < .05). When comparing low and high fit groups, correlations between AMs and indirect calorimetry improved for the low fit group, suggesting AMs may be better at measuring EE at lower intensity exercise.     

Humor and heuristics: culture,genre, and economic thought in The Big Short

This article uses the 2015 film, The Big Short, to explore the limits of representing and critiquing Wall Street culture on film. Critics have praised the film, suggesting that it offers an account of the 2007–2008 financial crisis that both critiques Wall Street culture and democratizes financial knowledge. I argue that the film is an early representative example of a public narrative based on behavioral economics. A popular movie informed by this discipline has a good deal of political potential for challenging injustices produced by neoliberal approaches to the financial services industry. However, I also argue that despite this political potential, The Big Short is unable to fundamentally challenge the belief in efficient markets that justify many of Wall Street’s practices. I also argue that the film uses unexamined and problematic understandings of both class and gender in characterizing the film’s protagonists.     

Walking-friendly built environments and objectively measured physical function in older adults

BackgroundFew studies have examined the associations between urban design attributes and older adults’ physical function. Especially, it is not well known how built-environment attributes may influence physical function in Asian cities. The aim of this study was to examine associations between objectively measured environmental attributes of walkability and objectively assessed physical function in a sample of Japanese older adults.MethodsCross-sectional data collected in 2013 from 314 older residents (aged 65–84 years) living in Japan were used. Physical function was estimated from objectively measured upper- and lower-body function, mobility, and balance by a trained research team member. A comprehensive list of built-environment attributes, including population density, availability of destinations, intersection density, and distance to the nearest public transport station, were objectively calculated. Walk Score as a composite measure of neighborhood walkability was also obtained.ResultsAmong men, higher population density, availability of destinations, and intersection density were significantly associated with better physical function performance (1-legged stance with eyes open). Higher Walk Score was also marginally associated with better physical function performance (1-legged stance with eyes open). None of the environmental attributes were associated with physical function in elderly women.ConclusionOur findings indicate that environmental attributes of walkability are associated with the physical function of elderly men in the context of Asia. Walking-friendly neighborhoods can not only promote older adults’ active behaviors but can also support their physical function.     

Shaping up? Three acts of education studies as textual critique

This paper presents a study of dominant educational discourses through textual critique and argues that such an approach enables education studies to preserve an important distinction from teacher training. The texts deconstructed here are specific to English education, but the discourses at work have international relevance as the rhetorics of accountability, performance and measurement (which we call cells of discourse) have global reach. Ward described a national picture in England whereby the great majority, if not all, of education studies undergraduate courses appear to be taught alongside, or within (through shared modules) teacher training programmes. But from a sociological position, these are two increasingly conflicting arenas—the study of education and the training of teachers. In response, Ward called for the subject to radicalize teacher education. The implications of this are significant if education studies is to retain a status as agent of critique. In this paper we return to the theme of education studies as a discrete practice from teacher training and suggest that any acceptance of a proximal relation to teacher education is counter‐productive. In so doing we offer three contemporary examples of the subject at deconstructive work, scrutinizing the published standards for teacher training in England, employer discourse and the Tomlinson report (commissioned by the English government to offer proposals for the reworking of vocational education) and the new curriculum for adult literacy in England. Particular attention is given to analysing the ways in which such texts speak the currently powerful discourse of standards.
