Associations between prolonged sedentary time and breaks in sedentary time with cardiometabolic risk in 10–14-year-old children: The HAPPY study

This study examines the association between prolonged sedentary time and breaks in sedentary time with cardiometabolic risk in 10–14-year-old children. This cross-sectional design study analysed accelerometry-determined sedentary behaviour and physical activity collected over 7 days from 111 (66 girls) UK schoolchildren. Objective outcome measures included waist circumference, fasting lipids, fasting glucose, blood pressure, and cardiorespiratory fitness. Logistic regression was used for the main data analysis. After adjustment for confounders, the odds of having hypertriglyceridaemia (P = 0.03) and an increased clustered cardiometabolic risk score (P = 0.05) were significantly higher in children who engaged in more prolonged sedentary bouts per day. The number of breaks in sedentary time per day was not associated with any cardiometabolic risk factor, but longer mean duration of daily breaks in sedentary time were associated with a lower odds of having abdominal adiposity (P = 0.04) and elevated diastolic blood pressure (P = 0.01). These associations may be mediated by engagement in light activity. This study provides evidence that avoiding periods of prolonged uninterrupted sedentary time may be important for reducing cardiometabolic disease risk in children.     

Internationalisation,Mobility and Metrics: A New Form of Indirect Discrimination?

This paper discusses the relationship between internationalisation, mobility, quality and equality in the context of recent developments in research policy in the European Research Area (ERA). Although these developments are specifically concerned with the growth of research capacity at European level, the issues raised have much broader relevance to those concerned with research policy and highly skilled mobility. The paper draws on a wealth of recent research examining the relationship between mobility and career progression with particular reference to a recently completed empirical study of doctoral mobility in the social sciences (Ackers et al. Doctoral Mobility in the Social Sciences. Report to the NORFACE ERA-Network, 2007). The paper is structured as follows. The first section introduces recent policy developments including the European Charter for Researchers and Code of Conduct for the Recruitment of Researchers and the European Commission’s Green Paper on the ERA. The discussion focuses on concerns around the definition of ‘mobility’ and the tendency (in both policy circles and academic research) to conflate different forms of mobility and to equate these with notions of excellence or quality. Scientific mobility is shaped as much by ‘push’ factors (limited opportunity) as it is by the ‘draw’ of excellence. Scientists are exercising a degree of ‘choice’ within a specific and individualised framework of constraints. The following sections consider some of the ‘professional’ and ‘personal’ factors shaping scientific mobility and the influence that these have on the relationship between mobility, internationalisation and excellence. The paper concludes that mobility is not an outcome in its own right and must not be treated as such (as an implicit indicator of internationalisation). To do so contributes to differential opportunity in scientific labour markets reducing both efficiency and equality.

Teaching Scientists to Communicate: Evidence-based assessment for undergraduate science education

Communication skills are one of five nationally recognised learning outcomes for an Australian Bachelor of Science (BSc) degree. Previous evidence indicates that communication skills taught in Australian undergraduate science degrees are not developed sufficiently to meet the requirements of the modern-day workplace—a problem faced in the UK and USA also. Curriculum development in this area, however, hinges on first evaluating how communication skills are taught currently as a base from which to make effective changes. This study aimed to quantify the current standard of communication education within BSc degrees at Australian research-intensive universities. A detailed evidential baseline for not only what but also how communication skills are being taught was established. We quantified which communication skills were taught and assessed explicitly, implicitly, or were absent in a range of undergraduate science assessment tasks (n?=?35) from four research-intensive Australian universities. Results indicate that 10 of the 12 core science communication skills used for evaluation were absent from more than 50% of assessment tasks and 77.14% of all assessment tasks taught less than 5 core communication skills explicitly. The design of assessment tasks significantly affected whether communication skills were taught explicitly. Prominent trends were that communication skills in tasks aimed at non-scientific audiences were taught more explicitly than in tasks aimed at scientific audiences, and the majority of group and multimedia tasks taught communication elements more explicitly than individual, or written and oral tasks. Implications for science communication in the BSc and further research are discussed.     

IMPACTS OF 2‐YEAR AND 4‐YEAR COLLEGES ON LEARNING ORIENTATIONS: A PRELIMINARY STUDY

This investigation compared the impacts of 2‐year and 4‐year colleges on learning orientations. Controlling for precollege learning orientations, academic aptitude, age, work, place of residence, and enrollment status, this study found no significant differences between 2‐ and 4‐year students in freshman‐year effects on enjoyment of diversity and intellectual challenge, learning for self‐understanding, internal locus of attribution for academic success, and preference for higher order cognitive activities. The findings are consistent with other recent evidence casting doubt on major differences in the net educational effects of 2‐ and 4‐year colleges.     

“It’s not them,it’s me”: competing discourses in one aspiring teacher’s talk

In this paper, we deploy M.M. Bakhtin’s notions about how language works to understand aspiring teachers’ struggles about the intersecting roles race, class, gender, language background, and sexual orientation play in students’ school lives and learning. Through life-history interviews and document analysis, we investigated the authoritative and internally persuasive discourses one aspiring teacher brought with her and took from a 15-week long course on a predominantly White Midwestern public university campus. Ideas she encountered in the course and its required tutoring component challenged her thinking about how various facets of people’s lives (such as those we list above) and the contexts in which they live, work and are schooled, affect how they are perceived, what they know, and can do.     

Prescription and reality: Reading advisers and reading practice, 1860–1880

Victorian Americans were serious readers: they expected books to contribute to their moral development. Yet not all the literature the marketplace provided served this purpose. Many readers therefore turned to reading advisers for suggestions about what to read and how to read it. The advice books they wrote, along with diaries and letters, tell us a great deal about Victorian reading practices and about the changing role of books and periodicals in mid-nineteenth-century society.     

Intervention in a Higher Education Market: a Case Study

In many countries today, public higher education operates within some form of market framework, typically a government‐regulated quasi‐market. However, having created a market environment, how should the government agencies involved act when they wish to use higher education to achieve a particular policy goal? This paper considers the impact on the English higher education market of an initiative by the national funding agency to expand Chinese studies. It is argued that, in an already competitive market, this intervention led to the misallocation of resources because it encouraged universities to expand provision in ways that they would not otherwise have done. As a result, although some effective new provision resulted, excess capacity was created overall. It can be argued that the collective understanding of the universities about this specific market was more accurate than that of an expert committee advising on national provision. The paper suggests how intervention might have been more effectively arranged.
