JointZone: users' views of an adaptive online learning resource for rheumatology

This paper describes an online learning resource for rheumatology that was designed for a wide constituency of users including primarily undergraduate medical students and health professionals. Although the online resources afford an informal learning environment, the site was pedagogically designed to comply with the general recommendations of the Standing Committee on Training and Education of EULAR (European League Against Rheumatism) for a rheumatology core curriculum. Any Internet user may freely browse the site content with optional registration providing access to adaptive features that personalize the user's view, for example, providing a reading history and targeted support based on scores from completed case studies. The site has now been available since early 2003, and an online survey of site registrants indicates that well structured pedagogical materials that reflect a learners' dominant ‘community of practice’ appear to be a successful aid to informal learning.     

How context shapes practitioner research and professional learning in schools in Singapore and NSW

The New South Wales (NSW) Government Department of Education and Communities and the Singapore Ministry of Education have encouraged teachers to engage in practitioner research as part of their professional learning agenda because it is perceived as a powerful means of investigating and improving educational practice. Drawing on a Schatzkian perspective, where social life is understood as being tied to a context, or ‘the site of the social’, we examine teachers’ experiences as practitioner researchers in NSW and Singapore. We also argue that practitioner research has been remodelled and re-interpreted differently in different contexts and that cultural context is a potent constituent of the practice architecture that prefigures practitioner research. Using data collected from interviews with 42 participants comprising academics, policy makers and teachers, we specifically illuminated those contextual/cultural characteristics respondents identified as factors that actively shape teachers’ experiences as practitioner researchers.     

Promoting Faculty Scholarship Through The University Author Recognition Bibliography at Boise State University

One of the most important contributions by any university is its faculty members’ scholarship. Providing an interface to view the full scope of an institution's academic accomplishments is vital for promoting both the scholarship and the university at large. Because of their unique information skills and services, librarians can facilitate the discovery of this scholarship on behalf of their institutions. This article explores how Albertsons Library at Boise State University utilizes an institutional repository to produce a faculty publication bibliography. Processes for collecting academic scholarship and organizing the citations within a repository structure are also discussed. Library staff found that this approach not only reduced redundancy and increased the usability of researcher publication data, it also increased the profile and value of the institutional repository.     

Curriculum,pedagogy, and the Cambridge Primary Review: a response to R.J. Campbell

Year after year, the interest in early learning of the state language by non-Estonian children has increased. In Estonia, the course has been directed that non-Estonian learners have to reach functional bilingualism by the time they leave basic school and thus to become competitive in labour and education markets in Estonia. The objective of the present study is to explain – based on the teachers’ assessments – meeting the objectives of the curriculum at the end of the kindergarten period and at the first stage of basic school by the children having participated in the early language immersion programme. The method of this study was a questionnaire. The results of this study showed that the children having been taught by the language immersion methods were well prepared for school, and their knowledge, linguistic skills and the capacity of self-expression were appropriate for their age in both languages.     

Relational and Overt Aggression in Middle Childhood: Early Child and Family Risk Factors

This study investigated early child and family risk factors for relational and overt aggression in 207 children followed since birth. Risk factors were assessed during infancy and preschool, and aggression in Grades 1, 3, and 5. Independent risk factors for Aggression Severity (total of relational and overt aggression) included lower language abilities, lower levels of temperamental withdrawal/inhibition, and greater exposure to family environments characterized by maternal negativity toward the child, family negative expressiveness, and maternal depression. The major risk factor for Aggression Directionality (relative preponderance of relational versus overt aggression) was gender. Child temperament interacted with family risk factors in predicting Severity, and child gender moderated the associations of temperament and family risk factors in predicting both Severity and Directionality.     

Special and inclusive education in the Eastern Caribbean: policy practice and provision

The countries of the Eastern Caribbean have for more than a decade been committed to the implementation of a common educational reform strategy. At the heart of this strategy has been the policy of 'education for all', which includes establishing educational support services for children with special educational needs. In the past, many disabled children and children with learning difficulties have been excluded from the education system in these countries. For many more children, attendance at school has not given meaningful access to educational opportunities. This article discusses research carried out by the authors and reports on the implementation of the Reform Strategy and on the barriers to inclusive education that persist in the region.     

Oxygen uptake kinetics in children and adults after the onset of moderate-intensity exercise

The literature suggests that the oxygen uptake ( V O 2 ) response to the onset of moderate-intensity exercise may be both mature from childhood and independent of sex. Yet the cardiorespiratory response to exercise and the metabolic profile of the muscle appear to change with growth and deve . lopment and to differ between the sexes. The aim of this study was to investigate further changes in the V O2 kinetic response with age and sex. Participants completed a series of no less than four step change transitions, from unloaded pedalling to a constant work rate corresponding to 80% of their previously determined ventilatory threshold. Each participant's breath-by-breath responses were interpolated to 1 s intervals, time aligned and then averaged. A single exponential model that included a time delay was used to analyse the averaged response following phase 1 (15 s). Participants with parameter confidence intervals more than - 5 s were removed from the sample; the results for the remaining 13 men and 12 women (age 19-26 years), 12 boys and 11 girls (age 11-12 years) were used for statistical analysis. Children had a significantly shorter time constant than adults, both for males (19.0 - 2.0 and 27.9 - 8.6 s respectively; P ? 0.01) and females (21.0 - 5.5 and 26.0 - 4.5 s respectively; P ? 0.05). There were no significant differences in the time constant between the sexes for either adults or children ( P > 0.05). A significant relationship between the time constant and peak V O 2 was found only in adult males ( P ? 0.05). A shorter time constant in children may reflect an enhanced potential for oxidative metabolism.     

Fluid and electrolyte needs for preparation and recovery from training and competition

For a person undertaking regular exercise, any fluid deficit that is incurred during one exercise session can potentially compromise the next exercise session if adequate fluid replacement does not occur. Fluid replacement after exercise can, therefore, frequently be thought of as hydration before the next exercise bout. The importance of ensuring euhydration before exercise and the potential benefits of temporary hyperhydration with sodium salts or glycerol solutions are also important issues. Post-exercise restoration of fluid balance after sweat-induced dehydration avoids the detrimental effects of a body water deficit on physiological function and subsequent exercise performance. For effective restoration of fluid balance, the consumption of a volume of fluid in excess of the sweat loss and replacement of electrolyte, particularly sodium, losses are essential. Intravenous fluid replacement after exercise has been investigated to a lesser extent and its role for fluid replacement in the dehydrated but otherwise well athlete remains equivocal.     

Measurement of maximal muscle cross-sectional area of the elbow extensors and flexors in children,teenagers and adults

Abstract

The aims of this study were to examine age and sex differences in elbow extensor and flexor anatomical muscle cross-sectional area (mCSA) measured by magnetic resonance imaging (MRI) and the location of maximal mCSA as a percentage of the distance from the distal to the proximal end of the humerus. Ninety-five individuals spread across the age groups 9 – 10 years, 16 – 17 years and 21 years participated in the study. Muscle cross-sectional area derived from the manual MRI tracing proved to be highly reliable in terms of limits of agreement (?2.5 to 1.5 cm²) and the intraclass correlation coefficient (ICC = 0.998). A sex-by-age group analysis of variance revealed significant effects (P < 0.01) of sex, group and a sex-by-group interaction, the latter reflecting a greater increase in males than females of upper arm mCSA from childhood to adulthood. Extensor mCSA was more proximal (55 ± 6%) than that of the flexors (28 ± 6%). A significant effect (P < 0.01) of group was found for location of maximal extensor mCSA, reflecting its more distal position with increasing age. Measurements of muscle size should be made at the individually determined position of maximal mCSA if interpreting data collected during growth and maturation, especially if the muscle group of interest is the elbow extensors and if different age groups are being monitored.
