A choice theory teaching and learning model for working with children of prisoners

The prison population has increased substantially in countries around the world and significant numbers of these prisoners are parents. Children of prisoners experience separation from the imprisoned parent. The separation and precursors to the separation often diminish these children's social‐emotional and educational well‐being. In this paper, the social‐emotional and educational functioning of children of prisoners is examined. Additionally, choice theory is described as a relevant theoretical teaching and learning model to facilitate the children's school‐related functioning.     

Developmental co‐ordination disorder (DCD): more than just a movement difficulty

Developmental co‐ordination disorder (DCD) also known as dyspraxia, is characterised by severe impairment of movement that has a detrimental effect on activities of daily living. This impairment of movement can be the result of poor planning or execution during an action. An assessment for DCD usually comprises of a standardised test for movement skills and clinical observations, but an assessment may not always consider both planning and/or execution components. This study used an ecologically valid task to examine how typically developing children compared with children with DCD plan and execute their movements in response to a novel movement challenge. Children were asked to cross a ‘river’ using as few ‘stepping stones’ (carpet tiles) as possible without falling in. The study measured a number of variables in order to construct a profile of the child's ability to plan and execute movements, including pattern and consistency of movement, and distance travelled by each child, as well as the ability to formulate and correct their plan. The results of this pilot study showed both differences and similarities between the two groups, with the DCD group showing more difficulties in planning, executing and in correcting their movements, as well as being more inconsistent in their movement patterns. The results are discussed in terms of the need for multiple measures for a complete assessment of a child, the implications for educational practice and the potential of an additional clinical tool to aid intervention in children with DCD.     

Inter‐professional work and expertise: New roles at the boundaries of schools

The findings discussed here are based on five case studies and a small survey (n = 46) of how secondary schools are responding to demands that they collaborate with other services to intervene to prevent the social exclusion of children and young people. The case studies revealed a new space of action opening up around schools where practices were being shaped by ‘welfare managers’ who were employed by schools and were undertaking responsive work with vulnerable children and young people and the other services who were also supporting them. At the same time heads of year and/or heads of school and form tutors were increasingly focusing on children's achievement in school. The changes in roles and responsibilities were encouraged by workforce remodelling and changes in criteria for teachers’ salaries. However, focusing primarily on the work undertaken by the welfare managers, the article draws on cultural‐historical activity theory analyses of relational agency and distributed expertise to question whether welfare managers can undertake the work required in the new space of action without attention to the development of their core expertise.     

Supply issues for science academics in Australia: now and in the future

Australia, like the rest of the developed world, is in the midst of dealing with notable issues related to the age structure of its academic workforce. These issues are widespread and have been articulated in the Australian context most comprehensively by Hugo (2008). This paper investigates issues with demographic change and other key factors related to the desirability of a science or mathematics academic career within Australian universities. It draws on the findings of a research project undertaken in 2008 for the Department of Education, Employment and Workplace Relations. The findings show that while demographic issues are not as dire for science academics compared to the entire sector, issues relating to tenure, workload and retaining young science academics in Australia are a threat to the long-term sustainability of science faculties in Australian universities.     

Observing response processes with eye tracking in international large-scale assessments: evidence from the OECD PIAAC assessment

This paper reports on a pilot study that used eye tracking techniques to make detailed observations of item response processes in the OECD Programme for the International Assessment of Adult Competencies (PIAAC). The lab-based study also recorded physiological responses using measures of pupil diameter and electrodermal activity. The study tested 14 adult respondents as they individually completed the PIAAC computer-based assessment. The eye tracking observations help to fill an ‘explanatory gap’ by providing data on variation in item response processes that are not captured by other sources of process data such as think aloud protocols or computer-generated log files. The data on fixations and saccades provided detailed information on test item response strategies, enabling profiling of respondent engagement and response processes associated with successful performance. Much of that activity does not include the use of the keyboard and mouse, and involves ‘off-screen’ use of pen and paper (and calculator) that are not captured by assessment log-files. In conclusion, this paper points toward an important application of eye tracking in large-scale assessments. This includes insights into response processes in new domains such as adaptive problem-solving that aim to identify individuals’ ability to select and combine resources from the digital and physical environment.     

The national politics of educational advocacy in the context of global governance: international funding and support for civil society engagement in Cambodia

This paper examines the Civil Society Education Fund’s (CSEF) impact on the non-governmental organisation education partnership (NEP) in Cambodia. With financial backing from the World Bank and the Fast Track Initiative, the CSEF is an initiative that is managed internationally by the Global Campaign for Education. Its goal is to help national networks of non-governmental organizations participate in education decision-making and to serve as a watchdog for progress related to internationally agreed upon goals. Through the CSEF, the deployment of various strategies, and other external factors, the NEP was able to able to achieve recognition, legitimacy and influence at the national level. However, the NEP has had to balance working with the state and working for the state. This case study highlights strategies used by civil society actors to engage state actors, the efficacy of international support, and the conflicts inherent in both.     

Leveraging community sport organizations to promote community capacity: Strategic outcomes,challenges, and theoretical considerations

Community sport organizations (CSOs) provide valuable contexts for promoting community development. These initiatives are most effective when they involve local stakeholders in the process of development. A key first step to achieving this objective is building community capacity, defined as local stakeholders’ skills, knowledge, and resources that may be leveraged for change. Interestingly, despite this conceptual importance, few researchers have focused on capacity building in the sport context. This has limited the theoretical advancement of community capacity theory as it relates to CSOs and community development. Using a qualitative case study approach, the authors analyze the outcomes and challenges of implementing community capacity building strategies in an American CSO, and draw on the empirical data to contribute to this theoretical conversation. Interviews, participant observation, and document analysis were used to generate data, and deductive techniques were used for thematic analysis. The results highlight the outcomes of the capacity building strategies and challenges associated with implementation. In addition, the conclusion focuses on theoretical contributions to community capacity theory, namely the role of sport in facilitating inter-community relations across social groups and the link with process models of organizational capacity.     

The effect of marathon running on carnitine metabolism and on some aspects of muscle mitochondrial activities and antioxidant mechanisms

Carnitine is an essential co‐factor in the catabolism of fats as an energy source. The primary purpose of this study was to investigate the effect of running a marathon on the metabolism of carnitine by endurance‐trained athletes, and to evaluate the effect of carnitine administration on the performance of such exercise. The effects of marathon running on mitochondrial enzymes and cellular anti‐oxidants were also examined to assess whether the expression of these activities is altered by exercise. Subjects were 10 experienced male marathon runners aged between 19 and 25 years. Running a marathon caused a fall in the plasma content of unesterified carnitine (37%) and an increase in the level of acetylcarnitine present (288%). Loading of the athletes with L‐carnitine for 10 days before running a marathon abolished the exercise‐induced fall in plasma‐free carnitine (P<0.05) whilst amplifying the production of acetylcarnitine (P<0.05). Carnitine loading of the athletes studied made no detectable improvement in performance of the marathon (P > 0.05). Cytochrome oxidase, succinate cytochrome C reductase and Superoxide dismutase activities present in skeletal muscle were unaltered by marathon running. However, such exercise caused a large increase in the tissue content of oxidized glutathione (189%) at the expense of reduced glutathione (–18%).     

Exercise does not necessarily influence the phase of the circadian rhythm in temperature in healthy humans

Seventeen healthy adults exercised for 30 min (70% V O 2max ), at different times of the day and night throughout a 24 h period. The effect on the phase of core temperature rhythm was assessed by comparing the rhythms on the day immediately before and immediately after the day of exercise with the participants living normally on these 2 days. Assessments were made upon data that had been corrected for the thermogenic effects of sleep and activity. When exercise was performed in the period between 4 h before and 1 h after the temperature minimum, there was a phase delay of 1.03 - 0.78 h (mean - s ; n = 6); when performed between 3 and 8 h after the temperature minimum, there was a phase advance of 1.07 - 1.23 h ( n = 9). Both means were significantly different from zero (Student's one-sample t -tests: P ? 0.05). Performed at other times, exercise had no significant effect on the phase of the temperature rhythm. The phase changes were not significantly different from those previously observed by us in sedentary individuals exposed to domestic lighting. We conclude that the amount of physical activity has very little effect on the body clock.     

Threshold frequency of an electrically induced cramp increases following a repeated,localized fatiguing exercise

Abstract

Though clinical observations and laboratory data provide some support for the neuromuscular imbalance theory of the genesis of exercise-associated muscle cramps, no direct evidence has been published. The purpose of this study was to determine the effect of local muscle fatigue on the threshold frequency of an electrically induced muscle cramp. To determine baseline threshold frequency, a cramp was electrically induced in the flexor hallucis brevis of 16 apparently healthy participants (7 males, 9 females; age 25.1 ± 4.8 years). The testing order of control and fatigue conditions was counterbalanced. In the control condition, participants rested in a supine position for 30 min followed by another cramp induction to determine post-threshold frequency. In the fatigue condition, participants performed five bouts of great toe curls at 60% one-repetition maximum to failure with 1 min rest between bouts followed immediately by a post-threshold frequency measurement. Repeated-measures analysis of variance and simple main effects testing showed post-fatigue threshold frequency (32.9 ± 11.7 Hz) was greater (P < 0.001) than pre-fatigue threshold frequency (20.0 ± 7.7 Hz). An increase in threshold frequency seems to demonstrate a decrease in one's propensity to cramp following the fatigue exercise regimen used. These results contradict the proposed theory that suggests cramp propensity should increase following fatigue. However, differences in laboratory versus clinical fatiguing exercise and contributions from other sources, as well as the notion of a graded response to fatiguing exercise, on exercise-associated muscle cramp and electrically induced muscle cramp should be considered.
