Background and aim: Paradoxically, recent investigations have showed that adiponectin levels are inversely associated with muscle strength. However, to date, there is a lack of knowledge on the relationship between muscular fitness (MF) and adiponectin levels in adolescents. We aimed to examine the independent associations between MF and adiponectin levels in adolescents, controlling for several potential confounders. Methods and results: This is a cross-sectional analysis with 529 Portuguese adolescents aged 12-18 years. A MF score was computed as the mean of the handgrip strength and standing long jump standardized values by age and gender. We measured fasting glucose, insulin, HDL-cholesterol, …

This chapter draws on six case studies of pedagogy with technology in Higher Education. The studies are chosen because they illustrate how the use of technology impacts on pedagogy in these contexts. While the cases are drawn from different levels of higher education (undergraduate to postgraduate) they are woven together by a shared framework: namely, the use of CHAT to explore pedagogical innovation with technology. One of the significant strengths of CHAT, all studies will argue, lies in its ability to situate goal-directed action within the larger context of a motive-directed activity. That is, its explanatory power lies in situating …

Research has demonstrated that physical activity involving gross motor activities can lead to better cognitive functioning and higher academic achievement scores. In addition, research within the theoretical framework of embodied cognition has shown that embodying knowledge through the use of more subtle motor activities, such as task-relevant gestures, has a positive effect on learning. In this study, we investigated whether combining both physical activities and gestures could improve learning even more in a 4-week intervention program on foreign language vocabulary learning in preschool children. The main hypothesis that learning by embodying words through task-relevant enactment gestures and physical activities would …

Development And Psychometric Properties Of The Y-Pass Questionnaire To Assess Correlates Of Lunchtime And After-School Physical Activity In Children, Rebecca M. Stanley, Kate Ridley, Timothy Olds, James Dollman

Faculty of Social Sciences - Papers (Archive)

Background

To frame interventions, it is useful to understand context- and time-specific correlates of children’s physical activity. To do this, we need accurate assessment of these correlates. There are currently no measures that assess correlates at all levels of the social ecological model, contain items that are specifically worded for the lunchtime and/or after-school time periods, and assess correlates that have been conceptualised and defined by children. The aim of this study was to develop and evaluate the psychometric properties of the lunchtime and after-school Youth Physical Activity Survey for Specific Settings (Y-PASS) questionnaires.

Methods

The Y-PASS questionnaire was administered …

Faculty of Social Sciences - Papers (Archive)

Background The lunchtime and after-school contexts are critical windows in a school day for children to be physically active. While numerous studies have investigated correlates of children's habitual physical activity, few have explored correlates of physical activity occurring at lunchtime and after-school from a social-ecological perspective. Exploring correlates that influence physical activity occurring in specific contexts can potentially improve the prediction and understanding of physical activity. Using a context-specific approach, this study investigated correlates of children's lunchtime and after-school physical activity. Methods Cross-sectional data were collected from 423 South Australian children aged 10.0-13.9 years (200 boys; 223 girls) attending 10 …

Improved Workflow Modelling Using Role Activity Diagram-Based Modelling With Application To A Radiology Service Case Study, Nagesh Shukla, John Keast, Darek Ceglarek

Faculty of Engineering and Information Sciences - Papers: Part A

The modelling of complex workflows is an important problem-solving technique within healthcare settings. However, currently most of the workflow models use a simplified flow chart of patient flow obtained using on-site observations, groupbased debates and brainstorming sessions, together with historic patient data. This paper presents a systematic and semi-automatic methodology for knowledge acquisition with detailed process representation using sequential interviews of people in the key roles involved in the service delivery process. The proposed methodology allows the modelling of roles, interactions, actions, and decisions involved in the service delivery process. This approach is based on protocol generation and analysis techniques …

Relative Validity Of 3 Accelerometer Models For Estimating Energy Expenditure During Light Activity, Alexander Allan Wetten, Marijka Batterham, Sze Yen Tan, Linda Tapsell

Faculty of Social Sciences - Papers (Archive)

Background: With physical inactivity inextricably linked to the increasing prevalence of obesity, there is a need for validated methods that measure free-living energy expenditure (EE) within sedentary environments. While accelerometers enable these measurements, few studies have compared device accuracy in such settings. The aim of this study was to investigate the relative validity of the Actigraph, RT3 and SenseWear Armband (SWA). Methods: Twenty-three (11 male, 12 female) participants (age: 25.3 ± 6.3 yr; BMI: 22.6 ± 2.7) wore 3 accelerometers at designated sites during a 4-hour stay in the Whole Room Calorimeter (WRC).

Measuring Adolescent Boys' Physical Activity: Bout Length And The Influence Of Accelerometer Epoch Length, Taren Sanders, Dylan Cliff, Chris Lonsdale

Faculty of Social Sciences - Papers (Archive)

Objectives

Accurate, objective measurement is important for understanding adolescents' physical activity (PA) behaviour. When using accelerometry to objectively measure PA, a decision must be made regarding how frequently data is recorded (i.e., epoch length). The purpose of this study was to examine i) PA bout length, and ii) the effect of variations in accelerometer epoch length on PA estimates during physical education (PE) and leisure time in adolescent boys.

Design

Cross-sectional study.

Methods

Year 9 boys (N=133; mean age ±SD =14.36±0.48 years) wore accelerometers during two PE lessons, and for a period of seven consecutive days. Data were reintegrated from …

Diarylacylhydrazones: Clostridium-Selective Antibacterials With Activity Against Stationary-Phase Cells, Chao Chen, Naveen K. Dolla, Gabriele Casadei, John B. Bremner, Kim Lewis, Michael J. Kelso

Faculty of Science, Medicine and Health - Papers: part A

Current antibiotics for treating Clostridium difficile infections (CDI), that is, metronidazole, vancomycin and more recently fidaxomicin, are mostly effective but treatment failure and disease relapse remain as significant clinical problems. The shortcomings of these agents are attributed to their low selectivity for C. difficile over normal gut microflora and their ineffectiveness against C. difficile spores. This Letter reports that certain diarylacylhydrazones identified during a high-throughput screening/counter-screening campaign show selective activity against two Clostridium species (C. difficile and Clostridium perfringens) over common gut commensals. Representative examples are shown to possess activity similar to vancomycin against clinical C. difficile strains and to …
