Participation in physical activity : perception of women with a previous history of gestational diabetes

The aim was to explore the perceptions of physical activity among women with previous gestational diabetes mellitus, in the context of preventing Type 2 diabetes mellitus.

How socio-economic status contributes to participation in leisure-time physical activity

The aim of this cross-sectional study was to identify individual, social, and environmental contributors (mediators) to individual- and area-level differences in leisure-time physical activity across socio-economic groups. A two-stage stratified sampling design was used to recruit 20–65 year old adults (N = 2194) living in 154 census collection districts of Adelaide, Australia (overall response rate: 12%). Participants completed two surveys six months apart (response rate on the second survey: 83%). Individual-level socio-economic status (SES) was assessed using self-report measures on educational attainment, household income, and household size. Area-level SES was assessed using census data on median household income and household size for each selected census district. Bootstrap generalized linear models were used to examine associations between SES, potential mediators, and leisure-time physical activity. The product-of-coefficient test was used to estimate mediating effects. All SES measures were independently associated with potential individual and social mediators of the SES-activity relationships. Individual- and area-level income was also associated with perceived neighborhood attributes. Self-efficacy and social support for physical activity explained virtually all of the differences in physical activity across educational attainment groups. Physical barriers to walking and access to public open space contributed in part to the explanation of differences in recreational walking across income groups. Yet, self-efficacy and social support were the key mediators of the observed relationships between individual- and area-level income and physical activity. This study suggests that in order to increase physical activity participation in the more disadvantaged segments of the population, comprehensive, multilevel interventions targeting activity-related attitudes and skills as well as social and physical environments are needed.

Girls challenging patriarchy through multimodal design and participation in online communities of practice.

This paper examines adolescent girls' multimodal design that challenges/resists patriarchy. Acts of uploading and multimodal design are discussed in terms of Bulter's theorisation of discursive performativity. The author suggests the girls employ a form of 'linguistic agency' or 'discursive agency' that allows them to make use of a wide range of multimodal design practices often unavailable in print dominated middle years classrooms. The girls in the study were involved in a set of relationships over time, both inside and outside of school in virtual and real time communities of practice. As a result, they engaged with particular areas of curricular knowledge differently than boys. The findings suggest that within online communities of practice, new contexts emerge where adolescent girls can contest the discourses of patriarchal power.

Online students : relationships between participation, demographics and academic performance

Using information technology to support teaching and learning is becoming ubiquitous in tertiary education. However, how students participate and perform when a major component of the learning experience is conducted via an online learning environment is still an open question. The objective of this study was to investigate whether any relationships existed between the participation, demographics and academic performance of students in an information technology course that was taught wholly online. Tracking data generated by the online learning environment was collected throughout the semester. Through a detailed analysis of this tracking data it was found that a relationship existed between students' participation in the online learning environment and their performance, as measured by final results in the course. Relationships also existed between gender, nationality, participation and performance. However, there was no relationship between age and performance and participation. These findings suggest that when designing online learning for a diverse population, student demographics should be taken into account to maximise the benefits of the learning experience. The results also suggest that the tracking data can be used as an early indicator of students who are likely to fail the course since lack of participation early in the semester is indicative of lower outcomes in the course. Being able to identify such students allows staff to take remedial action proactively rather than reactively in the latter part of the semester.

The democratic credentials of statutory bills of rights (and those of a self-styled majoritarian democrat)

This article has two aims. First, it seeks to demonstrate that the democratic credentials of statutory rights instruments are stronger than bills of rights sceptics such as Professors James Allan and Jeremy Waldron realise. It does so by examining the process by which statutory bills of rights are enacted and then provides an account as to why they are adopted that differs from the one offered by Allan and Waldron. This is done to suggest that the reason why a statutory rights instrument is adopted and the process itself has considerable democratic significance. And second, it seeks to assess the democratic credentials of Professor Allan's own critique of statutory bills of rights. The analysis undertaken in this regard reveals that in important respects Allan is anything but the majoritarian democrat that he routinely claims to be.
