Abstract: Various studies have discussed the pedagogical potential of video game play in the classroom but resistance to such texts remains high. The study presented here discusses the case study of one young boy who, having failed to learn to read in the public school system was able to learn in a private Sudbury model school where video games were not only allowed but considered important learning tools. Findings suggest that the incorporation of such new texts in today’s public schools have the potential to motivate and enhance the learning of children.
Psychopathology in Pediatric Epilepsy: Role of Antiepileptic Drugs

Frontiers in Neurology , 2012, DOI: 10.3389/fneur.2012.00163
Abstract: Children with epilepsy are usually treated with antiepileptic drugs (AEDS). Some AEDs adversely affect behavior in susceptible children. Since psychiatric comorbidity is prevalent in pediatric epilepsy, this paper attempts to disentangle these AED side effects from the psychopathology associated with this illness. It first outlines the clinical and methodological problems involved in determining if AEDs contribute to the behavior and emotional problems of children with epilepsy. It then presents research evidence for and against the role AEDs play in the psychopathology of children with epilepsy, and outlines how future studies might investigate this problem. A brief description of how to clinically separate out AED effects from the complex illness-related and psychosocial factors that contribute to the behavior difficulties of children with epilepsy concludes the paper.

‘There’s a hippo on my stoep’: Constructions of English second language teaching and learners in the new National Senior Certificate
Rochelle Kapp,Moeain Arend
Per Linguam : A Journal of Language Learning , 2011, DOI: 10.5785/27-1-94
Abstract: The focus of this paper is an analysis of the conceptualisation of language teaching and the construction of learners in the new National Senior Certificate grade 12 curriculum and examinations taken by students for whom English is an additional language. The paper examines the values, attitudes and beliefs, as well as the required levels of cognitive engagement and notions of reading and writing. The authors argue that the curriculum represents a significant improvement on the previous version. However, there is a considerable mismatch between the Curriculum Statement and the examination papers. The curriculum emphasis on the role of language as a tool for critical, independent thinking is not evident in the examination papers, which reinforce traditional gender norms and essentialised notions of Africa. The examination papers are cognitively undemanding, requiring only the most basic understandings of texts. The authors argue that, by making it possible to pass at a very basic level, the examination system in effect obscures the contradiction that although the majority of learners have to use English as a first language across the curriculum, the language itself is taught as a second language.
Analytical Solutions and Optimization of the Exo-Irreversible Schmidt Cycle with Imperfect Regeneration for the 3 Classical Types of Stirling Engine Solutions analytiques et optimisation du cycle de Schmidt irréversible à régénération imparfaite appliquées aux 3 types classiques de moteur Stirling
Rochelle P.,Grosu L.
Oil & Gas Science and Technology , 2011, DOI: 10.2516/ogst/2011127
Abstract: The “old” Stirling engine is one of the most promising multi-heat source engines for the future. Simple and realistic basic models are useful to aid in optimizing a preliminary engine configuration. In addition to new proper analytical solutions for regeneration that dramatically reduce computing time, this study of the Schmidt-Stirling engine cycle is carried out from an engineer-friendly viewpoint introducing exo-irreversible heat transfers. The reference parameters are the technological or physical constraints: the maximum pressure, the maximum volume, the extreme wall temperatures and the overall thermal conductance, while the adjustable optimization variables are the volumetric compression ratio, the dead volume ratios, the volume phase-lag, the gas characteristics, the hot-to-cold conductance ratio and the regenerator efficiency. The new normalized analytical expressions for the operating characteristics of the engine: power, work, efficiency, mean pressure, maximum speed of revolution are derived, and some dimensionless and dimensional reference numbers are presented as well as power optimization examples with respect to non-dimensional speed, volume ratio and volume phase-lag angle.analytical solutions. Le “vieux” moteur Stirling est l’un des moteurs a sources multiples d’energie les plus prometteurs pour le futur. Des modeles elementaires simples et realistes sont utiles pour faciliter l’optimisation de configurations preliminaires du moteur. En plus de nouvelles solutions analytiques qui reduisent fortement le temps de calcul, cette etude du cycle moteur de Schmidt-Stirling modifie est entreprise avec le point de vue de l’ingenieur en introduisant les exo-irreversibilites dues aux transferts thermiques. Les parametres de reference sont des contraintes technologiques ou physiques : la pression maximum, le volume maximum, les temperatures de paroi extremes et la conductance totale, alors que les parametres d’optimisation ajustables sont le rapport volumetrique de compression, les rapports de volume mort, le dephasage des volumes balayes, les caracteristiques du gaz, le rapport des conductances “chaude” et “froide” et l’efficacite du regenerateur. Des expressions analytiques nouvelles pour les caracteristiques de fonctionnement du moteur : puissance, travail, rendement, pression moyenne, vitesse maximale, sont etablies et quelques nombres de references adimensionnels ou pas sont presentes ainsi que des exemples d’optimisation de la puissance en fonction de la vitesse reduite (adimensionnelle), du rapport des volumes et de l’angle de dephasage.
