Raising awareness about climate change in Pacific communities

Community-based climate change projects in the Pacific typically seek to raise the awareness of locals about the consequences of climate change and changing weather patterns. A key concern is that such activities might be done in an ad hoc manner, with little consideration of local relevance, audience and the integration of local experiences and knowledge. Drawing on the results gleaned from an interactive focus group with 10 climate change practitioners working in the region, this exploratory study investigates why raising awareness about climate change remains crucial, and importantly, how such activities might be done in a more relevant, meaningful and empowering way at the community level in the Pacific. This commentary argues that it is essential for communities to make local sense of climate change, particularly in an ever-changing world where knowledge is continuously expanding and changing. Initial findings suggest that making local sense of and raising awareness about climate change readily comes about with due consideration of approach, audience and context.     

GIFTED EDUCATION IN JEWISH DAY SCHOOLS

Although there are many Jewish day schools within the United States, relatively few offer gifted programs. The schools that do offer programs differ from each other, offering various forms of enrichment. We discuss the exemplary standards for gifted programs established by the National Association for Gifted Children and illustrate how the standards could be applied to Jewish day schools. The information provided can be useful for decision making, implementing and improving gifted programs in Jewish day schools.     

Disruptive Relationships: Past and Present State of Educational Publishing in Australia

The article provides an overview of the historically colonial, dichotomous relationship of foreign-owned multinationals and locally owned independents in Australian educational publishing. I focus on the early settlement years, the development of educational publishing in the 19th century, the post-war dominance of Australian independents in the 20th century, the rise of foreign-owned multinationals from the mid-20th century, and the state of Australian educational publishing from the late 20th century.     

Telecommunications in rural America: An appraisal and a prediction

Abstract

Rural America has historically been plagued with a disproportionate shortage of health, education, and other public services. However, the application of rapidly changing telecommunications technologies can alleviate many of the problems associated with these isolated and “technologically undernourished” areas. Technologies such as low‐power television, direct broadcast satellites, and satellite‐fed cable services offer the opportunity for building a rural telecommunications network and thus improving services and the quality of life. However, in order for this goal to be realized, the economic constraints presented by insufficient consumer demand and unprofitable markets must be overcome. Direct government subsidization or increased support of projects may be necessary to encourage the private sector to increase investment in telecommunications facilities in rural communities.     

Effects of Age,Walking Speed,and Body Composition on Pedometer Accuracy in Children

The objective of this study was to investigate the effects of age group, walking speed, and body composition on the accuracy of pedometer-determined step counts in children. Eighty-five participants (43 boys, 42 girls), ages 5–7 and 9–11 years, walked on a treadmill for two-minute bouts at speeds of 42, 66, and 90 m·min^-1 while wearing a spring-levered (Yamax SW-200) and a piezoelectric (New Lifestyles NL-2000) pedometer. The number of steps taken during each bout was also recorded using a hand counter. Body mass index (BMI) was calculated from height and mass, and percentage of body fat (%BF) was determined using hand-to-foot bioelectrical impedance analysis. The tilt angle of the pedometer was assessed using a magnetic protractor. Both pedometers performed well at 66 and 90 m·min^-1, but undercounted steps by approximately 20% at 42 m·min^-1. Although age group, BMI, waist circumference, and %BF did not affect pedometer accuracy, children with large pedometer tilt angles (≥ 10°) showed significantly greater percent bias than those with small tilt angles (< 10°). We suggest that the style of waistband on the child's clothing is a more important determinant of tilt angle and thus pedometer accuracy than body composition. Our results also indicate that the NL-2000 pedometer provides similar accuracy and better precision than the SW-200 pedometer, especially in children with large tilt angles. We conclude that fastening pedometers to a firm elastic belt may improve stability and reduce undercounting in young people.     

Effects of time of day and distance upon accuracy and consistency of throwing darts

Abstract

We examined variations in dart-throwing performance during the daytime in 12 participants. Two distances from the dartboard were investigated – the normal distance (short throws) and another 50% further away than this (long throws). Intra-aural temperature and subjective fatigue were measured, and errors in performance were assessed as the radial distances of throws from the bulls-eye and the standard deviation of these distances. Long-distance throws improved significantly throughout the daytime and correlated positively with intra-aural temperature (r = ?0.49, P = 0.002 and r = ?0.49, P = 0.002 for errors and standard deviation of errors, respectively), but not with subjective fatigue (r = ?0.10, P = 0.56 and r = ?0.05, P = 0.74 for errors and standard deviation of errors, respectively). Short-distance throws were associated less with intra-aural temperature (r = ?0.46, P = 0.005 and r = ?0.17, P = 0.31 for errors and standard deviation of errors, respectively), and worsened with fatigue (r = +0.34, P = 0.040 for errors). Compared with the short-distance throws, the long-distance throws were performed significantly less well than could be accounted for by the increased distance (mean errors were increased 1.67 – 2.78 times and standard deviation of errors of errors 1.58 – 3.68 times), supporting the concept of a trade-off between force of contraction and accuracy of performance. Throwing darts can be used as a model for investigating factors that influence motor performance, and our results indicate that the effects of time of day upon performance depend upon the relative importance of force and accuracy.     

Prediction of habitual physical activity level and weight status from fundamental movement skill level

Abstract

Fundamental movement skills (FMS) have been assessed in children in order to investigate the issues of the low proportion of children who meet physical activity (PA) guidelines and rising levels of obesity. The aim of this research was to identify whether previous or current FMS level is a better predictor of PA levels and weight status in children. In January 2012 (year 1), 281 children were recruited from one primary school in the West Midlands, UK. Children performed eight FMS three times, which were videoed and assessed using a subjective checklist. Sprint speed and jump height were measured objectively. Height and mass were measured to calculate the body mass index to determine the weight status. Skinfold calliper readings were used to calculate body fat percentage. One year later, in January 2013, all these tests were repeated on the same children, with the additional collection of PA data via the use of pedometers. Following multiple linear regression, it was identified that prior mastery in FMS was a better predictor of current PA, whereas current FMS was a better predictor of current weight status. Overall, FMS mastery is needed in childhood to be able to participate in PA and maintain a healthy weight status.
