Two Time-Scale Feedback Stabilization of Linear Time-Varying Singularly Perturbed Systems

The stabilization of a class of singularly perturbed linear time-varying systems is considered through the separate stabilization of two lower dimensional subsystems in two different time-scales. A composite stabilizing controller is synthesized from the separate stabilizing controllers of the two subsystems, the mutually independent gains of which do not require knowledge of the small singular perturbation parameter.     

How do teachers in Ireland and England conceptualise dyslexia?

This paper presents the findings of a comparative study using data from questionnaire surveys carried out in England (n=57) and Ireland (n=72). The researchers examine how teachers and teaching assistants who are currently teaching pupils with dyslexia in primary schools describe dyslexia and what may have influenced their conceptualisation. The paper examines teachers' responses both in terms of how they view their pupils presenting difficulties in the classroom, and how far they link these to underlying differences in cognitive processing. The researchers suggest ways in which this might influence their teaching in terms of methodology. Findings have been mapped to the Morton and Frith causal modelling framework. The implications of these findings for the training and support of teachers are discussed in the light of recent national initiatives to improve the teaching of dyslexic pupils in both countries.     

Globalization,China’s drive for world-class universities (211 Project) and the challenges of ethnic minority higher education: the case of Yanbian university

This case study of Yanbian University, a Korean minority university in China, examines the challenges faced, strategies employed, and resources mobilized by a minority university in its attempt to become a world-class university. Specifically, this case study focuses on how the University is attempting to reach its goals within the context of the 211 Project, China’s plan to create 100 world-class universities capable of meeting the challenges of the 21st century. The rise of the knowledge economy has resulted in an increased link between economic prosperity and higher education. Thus, higher education reform has explicitly tied higher education to economic development and attempted to transform economic structures by turning the labor force into a highly skilled, technologically competent, educated work force capable of competing in a global economy. The socioeconomic changes that have occurred as a result of globalization and China’s transition to a market economy have also created new imperatives and challenges for higher education institutions, particularly among minority higher education institutions endeavoring to carve out a unique place in China’s higher education landscape.     

Prediction of segmental lean mass using anthropometric variables in young adults

The aim of the present study was to develop and cross-validate anthropometrical prediction equations for segmental lean tissue mass (SLM). One hundred and seventeen young healthy Caucasians (67 men and 50 women; mean age: 31.9 ± 10.0 years; Body Mass Index: 24.3 ± 3.2 kg · m(-2)) were included. Body mass (BM), stretch stature (SS), 14 circumferences (CC), 13 skinfolds (SF) and 4 bone breadths (BB) were used as anthropometric measurements. Segmental lean mass of both arms, trunk and both legs were measured by dual energy X-ray absorptiometry as the criterion method. Three prediction equations for SLM were developed as follows: arms = 40.394(BM) + 169.836(CCarm-tensed) + 399.162(CCwrist) - 85.414(SFtriceps) - 39.790(SFbiceps) - 7289.190, where Adj.R (2) = 0.97, P < 0.001, and standard error of estimate (SEE) = 355 g;trunk = 181.530(BM) + 155.037(SS) + 534.818(CCneck) + 175.638(CCchest) - 88.359(SFchest) - 147.232(SFsupraspinale) - 46522.165, where Adj.R(2) = 0.97, P < 0.001, and SEE = 1077g; and legs = 55.838(BM) + 88.356(SS) + 235.579(CCmid-thigh) + 278.595(CCcalf) + 288.984(CCankle) - 84.954(SFfront-thigh) - 53.009(SFmedial calf) - 28522.241, where Adj.R (2) = 0.96, P < 0.001, and SEE = 724 g. Cross-validation statistics showed no significant differences (P < 0.05) between observed and predicted SLM. Root mean squared errors were smallest for arms (362 g), followed by legs (820 g) and trunk (1477 g). These new prediction equations allow an accurate estimation of segmental lean mass in groups of young adults, but estimation errors of 8 to 14% can occur in certain individuals.     

Interactive whiteboards and talking books: a new approach to teaching children to write?

This article presents work undertaken with a class of Scottish Primary Six children (aged 10) to investigate the use of interactive whiteboard technology and interactive talking books in whole‐class writing lessons. The paper reports on a research project with three aims: to investigate how the use of an interactive whiteboard to reflect on the language and style of professional authors influenced the children's own writing; to examine the effect of this experience on the writing and behaviour of children with additional support needs; and to identify the advantages and disadvantages of using such technology in whole‐class writing lessons. The resulting evidence suggests that while some children benefited from the approach, teaching children to write through examination of professional models of writing in whole‐class lessons did not promote the most effective learning even where the text was provided in such an interactive medium. The implications of these results for practitioners who wish to use talking books and whiteboard technology to teach writing are discussed.     

The international face of sports science through the window of the Journal of Sports Sciences--with a special reference to kinanthropometry

The history of the Journal of Sports Sciences is traced from the antecedents of its initiation to the current time. The developments of the sports sciences at large are reflected in the content of the journal. Its links with the international agenda are described, and related to landmark publications. Special attention is given to the relationships with international bodies, the International Society for Advancement of Kinanthropometry and the World Commission of Science and Sports. The expansion of sport and exercise sciences, both nationally and internationally, was reflected in the increased frequency of publication of the journal. Key areas in the kinanthropometric content are identified and placed in context. The review culminates in the highlighting of likely areas for future research.
