Understanding the balance of experienced teachers' ICT learning

In the Information Age, ICT learning requires a balance between the concrete and experiential learning process and the abstract conceptualisation of Andragogy. Future Teacher Professional Development will need to understand the complexities of the concrete experience and the abstract conceptualisation of new knowledge. Professional Development will need to comprehend how experienced teachers as digital immigrants learn. It will further need to understand what abilities are essential for these experienced teachers and how they develop an awareness of their ICT learning. This paper will examine a study that was undertaken with a group of Post Registration Primary School Educators. These experienced teachers undertook the Post Registration or fourth year of their Bachelor of Education (Primary) course at an Australian Educational Institute. These experienced teachers with limited ICT exposure went through an ICT learning process over a period of one year. They finally acquired the ICT knowledge and skills, however within the time span of one year, theoretical pedagogy was absent or minimal.

The Dutch Obesity Intervention in Teenagers (DOiT) cluster controlled implementation trial: intervention effects and mediators and moderators of adiposity and energy balance-related behaviours

 Background: The Dutch Obesity Intervention in Teenagers (DOiT) programme is an evidence-based obesity prevention programme tailored to adolescents attending the first two years of prevocational education in the Netherlands. The initial programme showed promising results during an effectiveness trial. The programme was adapted and prepared for nationwide dissemination. To gain more insight into the process of translating evidence-based approaches into ‘real world’ (i.e., ‘natural’) conditions, our research aims were to evaluate the impact of the DOiT-implementation programme on adolescents’ adiposity and energy balance-related behaviours during natural dissemination and to explore the mediating and moderating factors underlying the DOiT intervention effects.
Methods: We conducted a cluster-controlled implementation trial with 20 voluntary intervention schools (n=1002 adolescents) and 9 comparable control schools (n = 484 adolescents). We measured adolescents’ body height and weight, skinfold thicknesses, and waist circumference. We assessed adolescents’ dietary and physical activity behaviours by means of self-report. Data were collected at baseline and at 20-months follow-up. We used multivariable multilevel linear or logistic regression analyses to evaluate the intervention effects and to test the hypothesised behavioural mediating factors. We checked for potential effect modification by gender, ethnicity and education level.
Results: We found no significant intervention effects on any of the adiposity measures or behavioural outcomes. Furthermore, we found no mediating effects by any of the hypothesised behavioural mediators. Stratified analyses for gender showed that the intervention was effective in reducing sugar-containing beverage consumption in girls (B = -188.2 ml/day; 95% CI = -344.0; -32.3). In boys, we found a significant positive intervention effect on breakfast frequency (B = 0.29 days/week; 95% CI = 0.01; 0.58). Stratified analyses for education level showed an adverse intervention effect (B = 0.09; 95% CI = 0.02; 0.16) on BMI z-scores for adolescents attending the vocational education track.
Conclusions: Although not successful in changing adolescents’ adiposity, the DOiT-implementation programme had some beneficial effects on specific obesity-related behaviours in subgroups. This study underlines the difficulty of translating intervention effectiveness in controlled settings to real world contexts. Adaptations to the implementation strategy are needed in order to promote implementation as intended by the teachers.

Board strategic balance: an emerging sport governance theory

Despite the important role governing boards play in organisational life our understanding of their strategic function is limited. This paper embarks on theory development to explain the notion of board strategic capability and to identify the factors and their relationships influencing strategic capability of sport boards. This little-used construct, we argue, can guide future governance research. In reflecting on the extant literature from the nonprofit, for-profit and sport governance domains, we derived six distinct and central factors of board strategic capability: increasing contribution of volunteer board members ('will and skill'); board operational knowledge; board integrating regional entities into the governing role; board maintaining the monitoring and control function; board co-leading strategy development; and board co-leading integration of strategy into board processes. In considering the relationships between these six factors, we propose a theory of 'board strategic balance' that explains these influences in a holistic model. We conclude that the theory of board strategic capability is encapsulated by understanding how creating and maintaining . equilibrium in these roles and functions is managed by sport boards.

Lower limb progressive resistance training improves leg strength but not gait speed or balance in Parkinson's disease: a systematic review and meta-analysis.

The use of progressive resistance training (PRT) to improve gait and balance in people with Parkinson's disease (PD) is an emerging area of interest. However, the main effects of PRT on lower limb functions such as gait, balance, and leg strength in people with PD remain unclear. Therefore, the aim of the meta-analysis is to evaluate the evidence surrounding the use of PRT to improve gait and balance in people with PD. Five electronic databases, from inception to December 2014, were searched to identify the relevant studies. Data extraction was performed by two independent reviewers and methodological quality was assessed using the PEDro scale. Standardized mean differences (SMD) and 95% confidence intervals (CIs) of fixed and random effects models were used to calculate the effect sizes between experimental and control groups and I (2) statistics were used to determine levels of heterogeneity. In total, seven studies were identified consisting of 172 participants (experimental n = 84; control n = 88). The pooled results showed a moderate but significant effect of PRT on leg strength (SMD 1.42, 95% CI 0.464-2.376); however, no significant effects were observed for gait speed (SMD 0.418, 95% CI -0.219 to 1.055). No significant effects were observed for balance measures included in this review. In conclusion, our results showed no discernable effect of PRT on gait and balance measures, although this is likely due to the lack of studies available. It may be suggested that PRT be performed in conjunction with balance or task-specific functional training to elicit greater lower limb functional benefits in people with PD.

Flight altitude of trans-Sahara migrants in autumn: a comparison of radar observations with predictions from meteorological conditions and water and energy balance models

Radar observations on the altitude of bird migration and altitudinal profiles of meteorological conditions over the Sahara desert are presented for the autumn migratory period. Migratory birds fly at an average altitude of 1016 m (a.s.l.) during the day and 571 m during the night. Weather data served to calculate flight range using two models: an energy model (EM) and an energy-and-water model (EWM). The EM assumes that fuel supply limits flight range whereas the EWM assumes that both fuel and water may limit flight range. Flight ranges estimated with the EM were generally longer than those with the EWM. This indicates that trans-Sahara migrants might have more problems balancing their water than their energy budget. However, if we assume fuel stores to consist of 70% instead of 100% fat (the remainder consisting of 9% protein and 21% water), predicted flight ranges of the EM and EWM largely overlap. Increased oxygen extraction, reduced flight costs, reduced exhaled air temperature, reduced cutaneous water loss and increased tolerance to water loss are potential physiological adaptations that would improve the water budget in migrants. Both the EM and EWM predict optimal flight altitudes in agreement with radar observations in autumn. Optimal flight altitudes are differently predicted by the EM and EWM for nocturnal spring migration. During spring, the EWM predicts moderately higher and the EM substantially higher flight altitudes than during autumn. EWM predictions are therefore in better agreement with radar observations on flight altitude of migrants over the Negev desert in spring than EM predictions.

Impact of individual coping strategies and organisational work–life balance programmes on Australian employee well-being

This paper examines several individual coping strategies and employees' perception of organisational provision of work–life balance (WLB) programmes with a sample of 700 Australian employees. The combined effects of individual coping strategies and organisational provision of WLB programmes on employee affective well-being are examined, using structural equation modelling. Results indicate that individuals with positive attitudes and life coping strategies were more capable of achieving overall well-being. Both monetary- and non-monetary-based organisational WLB provision had no direct association with employee well-being, but had indirect effects via individual coping strategies to help employees achieve better well-being. Employee well-being was found to have a stronger association with individual effort than organisational deliberation in providing WLB programmes. Theoretical and practical implications of these study outcomes are discussed.

Australian government budget balance numbers: the hybrid nature of public sector accrual accounting

Purpose - The purpose of this paper is to analyse the nature and comparability of budget balance (surplus/deficit) numbers headlined by the Australian Commonwealth Government and the governments of the six Australian States and the two Australian Territories. It does this in the context of the transition to Australian accounting standard AASB 1049 Whole of Government and General Government Sector Financial Reporting. Design/methodology/approach - A case study research method is adopted, based on a content/documentary analysis of the headline budget balance numbers in the general government sector budget statements of each of the nine governments for the eight financial years from 2004-2005 to 2011-2012. Findings - Findings indicate some variation in the measurement bases adopted and a number of departures from the measurement bases prescribed in the reporting frameworks, including AASB 1049. Findings also reveal that none of the nine governments have headlined a full accrual based budget balance number since the implementation of AASB 1049 in 2008. Research limitations/implications - While the study focuses on the Australian general government sector environment, it has significant implications in highlighting the ambiguity in the government budget balance numbers presented and the monitoring and information asymmetry problems that can arise. Research findings have wider relevance internationally in highlighting issues arising with the public sector adoption of accrual accounting. Practical implications - The paper highlights the manner in which governments have been selective in the manner in which they present important budget aggregates. This has important practical and social implications, as the budget balance number is one of the most important measures used to evaluate a government's fiscal management and responsibility. Originality/value - The paper represents the first detailed examination of aspects of the effect of the transition to AASB 1049.

Vibration or balance training on neuromuscular performance in osteopenic women

Maintaining neuromuscular function in older age is an important topic for aging societies, especially for older women with low bone density who may be at risk of falls and bone fracture. This randomized controlled trial investigated the effect of resistive exercise with either whole-body vibration training (VIB) or coordination/balance training (BAL) on neuromuscular function (countermovement jump, multiple 1-leg hopping, sit-to-stand test). 68 postmenopausal women with osteopenia or osteoporosis were recruited for the study. 57 subjects completed the 9-month, twice weekly, intervention period. All subjects conducted 30 min of resistance exercise each training day. The VIB-group performed additional training on the Galileo vibration exercise device. The BAL-group performed balance training. An "intent-to-treat" analysis showed greater improvement in the VIB-group for peak countermovement power (p=0.004). The mean [95% confidence interval] effect size for this parameter was a  + 0.9[0.3 to 1.5] W/kg greater change in VIB than BAL after 9 months. In multiple 1-leg hopping, a significantly better performance in the VIB-group after the intervention period was seen on a "per-protocol" analysis only. Both groups improved in the sit-to-stand test. The current study provides evidence that short-duration whole-body vibration exercise can have a greater impact on some aspects of neuromuscular function in post-menopausal women with low bone density than proprioceptive training.

Fundamental movement skills are more than run, throw and catch: the role of stability skills

INTRODUCTION: In motor development literature fundamental movement skills are divided into three constructs: locomotive, object control and stability skills. Most fundamental movement skills research has focused on children's competency in locomotor and object control skills. The first aim of this study was to validate a test battery to assess the construct of stability skills, in children aged 6 to 10 (M age = 8.2, SD = 1.2). Secondly we assessed how the stability skills construct fitted into a model of fundamental movement skill. METHOD: The Delphi method was used to select the stability skill battery. Confirmatory factor analysis (CFA) was used to assess if the skills loaded onto the same construct and a new model of FMS was developed using structural equation modelling. RESULTS: Three postural control tasks were selected (the log roll, rock and back support) because they had good face and content validity. These skills also demonstrated good predictive validity with gymnasts scoring significantly better than children without gymnastic training and children from a high SES school performing better than those from a mid and low SES schools and the mid SES children scored better than the low SES children (all p < .05). Inter rater reliability tests were excellent for all three skills (ICC = 0.81, 0.87, 0.87) as was test re-test reliability (ICC 0.87-0.95). CFA provided good construct validity, and structural equation modelling revealed stability skills to be an independent factor in an overall FMS model which included locomotor (r = .88), object control (r = .76) and stability skills (r = .81). DISCUSSION: This study provides a rationale for the inclusion of stability skills in FMS assessment. The stability skills could be used alongside other FMS assessment tools to provide a holistic assessment of children's fundamental movement skills.
