Age-Related Changes in Visual Spatial Working Memory Cognits: Frontal-Parietal EEG Coherence During Delay

This study explored changes in scalp electrophysiology across two Working Memory (WM) tasks and two age groups. Continuous electroencephalography (EEG) was recorded from 18 healthy adults (18-34 years) and 12 healthy adolescents (14-17) during the performance of two Oculomotor Delayed Response (ODR) WM tasks; (i.e. eye movements were the metric of motor response). Delay-period, EEG data in the alpha frequency was sampled from anterior and parietal scalp sites to achieve a general measure of frontal and parietal activity, respectively. Frontal-parietal, alpha coherence was calculated for each participant for each ODR-WM task. Coherence significantly decreased in adults moving across the two ODR tasks, whereas, coherence significantly increased in adolescents moving across the two ODR tasks. The effects of task in the adolescent and adult groups were large and medium, respectively. Within the limits of this study, the results provide empirical support that WM development during adolescence include complex, qualitative, change.

Working Memory in the Junior/Intermediate Classroom

This research project explored the connection between working memory and children’s learning. The project created a resource titled Working Memory Strategies for the Junior/ Intermediate Educator: A Handbook based on a literature review, the deconstruction of theoretical and empirical studies, teacher resources, and findings from a needs assessment completed by teachers that together show there is insufficient support for teachers working with students who have deficits in working memory along with other common classroom learning disabilities. As learning disabilities become more common in the classroom that increasingly affect working memory in a majority of cases, teachers must be prepared not only to address specific symptoms of the conditions, but also to help students learn how to navigate and become aware of their working memory ability. The handbook thus was developed as a useful resource for teachers looking to expand their knowledge about how learning occurs. A needs assessment completed by junior and intermediate division teachers in Ontario helped determine what educators found most important for inclusion in the handbook, and the same teachers were offered the opportunity to review the completed handbook. Teacher participants provided constructive feedback and indicated that the handbook would be a valuable resource for them and their colleagues when working with students who have working memory issues. It was suggested that the handbook would be useful when creating students’ Individual Education Plans and that the assessment checklist included in the handbook would be an excellent resource for teachers collecting data regarding students’ working memory and ability to learn.

Working Together: Librarian and Student Collaboration Through Active Learning in a Library Eclassroom

Active learning strategies based on several learning theories were incorporated during instruction sessions for second year Biological Sciences students. The instructional strategies described in this paper are based primarily on sociocultural and collaborative learning theory, with the goal being to expand the relatively small body of literature currently available that discusses the application of these learning theories to library instruction. The learning strategies employed successfully involved students in the learning process ensuring that the experiences were appropriate and effective. The researchers found that, as a result of these strategies (e.g. teaching moments based on the emerging needs of students) students’ interest in learning information literacy was increased and students interacted with information given to them as well as with their peers. Collaboration between the Librarians, Co-op Student and Senior Lab Instructor helped to enhance the learning experience for students and also revealed new aspects of the active learning experiences. The primary learning objective, which was to increase the students’ information skills in the Biological Sciences, was realized. The advantages of active learning were realized by both instructors and students. Advantages for students attained during these sessions include having their diverse learning styles addressed; increased interaction with and retention of information; increased responsibility for their own learning; the opportunity to value not only the instructors, but also themselves and their peers as sources of authority and knowledge; improved problem solving abilities; increased interest and opportunities for critical thinking, as a result of the actively exchanging information in a group. The primary advantage enjoyed by the instructors was the opportunity to collaborate with colleagues to reduce the preparation required to create effective library instruction sessions. Opportunities for further research were also discovered, including the degree to which “social loafing” plays a role in collaborative, active learning.

Land Ownership, Working Capital, and the Agricultural Output: Egypt, 1913-1958.

A simple model is constructed in which short-term credit is needed to finance the purchase of inputs, in which there is bankruptcy risk, and in which we argue were important characteristics of Egyptian agriculture during the first half of this century, result in aggregate agricultural output being dependant on the distribution of land ownership. The main theorical insight is that aggregate agricultural output will be increased by a decrease in the inequality of the distribution of land ownership when returns to scale are decreasing. Testable short- and long-run empirical propositions are formulated and carefully tested on Egyptian data for the 1913-1958 period. We find that, controlling for factor inputs, there is no tradeoff between equity and efficiency for Egyptian agriculture - they go hand in hand in the short run.

Working Children: their Agency and self-organization

In recent years, ‘agency’ has appeared in academic writings as a new way of referring to active involvement from below in development interventions. The concept of ‘agency’ starts from the assumption that people are actually agents themselves, continuously acting in and reacting to circumstances. In child labour activism, this concept has been applied to working children in the understanding that, in order to improve their working conditions, children should be organised in organizations that are exclusively for and (ideally) run by working children. This paper aims to evaluate the extent to which child labourers can become agents of change through their own organizations. The paper will draw on two studies carried out by the IREWOC foundation. In 2002 a study was undertaken in Bolivia to give practical meaning to the concept of child agency. Secondly, in 2004/2005 an investigation was carried out on the functioning and impact of children’s organizations in Peru, Bolivia and Brazil. The applied research methods were mainly anthropological and used participant observation, (semi-) informal interviews and group interviewing with working children, their parents and adult representatives of the working children’s organizations. Both investigations show that in focussing on children as active participants, the structural constraints under which children have to live also need to be highlighted. One needs to understand how material poverty, mental deprivation and disempowerment help to shape resilience and defiance, but also anger, distrust and marginalisation.

Introduction: Working in Development Ethics – a tribute to Denis Goulet

Denis Goulet (1931-2006) was probably the main founder of work on ‘development ethics’ as a self-conscious field that treats the ethical and value questions posed by development theory, planning and practice. This overview of a selection of papers presented at a conference of the International Development Ethics Association (Uganda, 2006) surveys Goulet’s work and compares it with issues and approaches in the selected papers. Ideas raised by Goulet provide a framework for discussing the set of papers, which especially consider corruption, professional ethics and the rights to water and essential drugs. The papers in turn provide a basis for comparing Goulet’s ideas with actual directions of work on development ethics. Rather than as a separate sub-discipline, development ethics takes shape as an interdisciplinary meeting place, aided though by the profile and intellectual space that Goulet strikingly strove to build for it.

AURA : a hybrid approach to identify framework evolution

Les cadriciels et les bibliothèques sont indispensables aux systèmes logiciels d'aujourd'hui. Quand ils évoluent, il est souvent fastidieux et coûteux pour les développeurs de faire la mise à jour de leur code. Par conséquent, des approches ont été proposées pour aider les développeurs à migrer leur code. Généralement, ces approches ne peuvent identifier automatiquement les règles de modification une-remplacée-par-plusieurs méthodes et plusieurs-remplacées-par-une méthode. De plus, elles font souvent un compromis entre rappel et précision dans leur résultats en utilisant un ou plusieurs seuils expérimentaux. Nous présentons AURA (AUtomatic change Rule Assistant), une nouvelle approche hybride qui combine call dependency analysis et text similarity analysis pour surmonter ces limitations. Nous avons implanté AURA en Java et comparé ses résultats sur cinq cadriciels avec trois approches précédentes par Dagenais et Robillard, M. Kim et al., et Schäfer et al. Les résultats de cette comparaison montrent que, en moyenne, le rappel de AURA est 53,07% plus que celui des autre approches avec une précision similaire (0,10% en moins).

Généalogie des résistances cinématographiques : le cas de trois machines autopoïétiques (Eisenstein, Syberberg, Welles)

Notre thèse s’attache à définir certains rapports possibles entre le cinéma et le politique ou, plus précisément, entre le cinéma et le concept pratique de résistance. Il existe une théorie de la résistance, soit sous la forme d’une cartographie du pouvoir moléculaire (M. Foucault), soit sous la forme d’une analytique de la résistance (F. Proust). Il existe également une théorie de la résistance cinématographique, soit comme sociologie ou histoire de l’action politique par le cinéma (cinéma de la Résistance, cinéma militant), soit comme une sémiotique des formes et des genres marginaux (cinéma expérimental, cinéma des avant-gardes). Suivant une direction tracée par Serge Daney et Gilles Deleuze, nous croyons qu’il faut poser autrement le problème : si « le politique est affaire de perception », alors la résistance est d’abord une invention de visibilité et d’audibilité. En ce sens, la résistance cinématographique est une exploration de ce que peut le cinéma, tant d’un point de vue esthétique, éthique, que politique. D’où notre hypothèse, qui est double : d’une part, cette invention de visibilité, cette création de potentiel n’est peut-être possible qu’en passant par un ré-enchaînement anachronique d’une déformation plastique, narrative et audiovisuelle à une autre, c’est-à-dire d’une survivance à une autre. D’autre part, nous croyons qu’une forme esthétique est en soi matière politique et manière de politique, et qu’elle implique également une éthique venant brasser notre propre subjectivité (de cinéaste, de spectateur, de citoyen, etc.). Or, pour saisir cette invention de visibilité inhérente au cinéma, il faut en passer par une généalogie de certaines alliances théoriques et pratiques parmi les plus importantes. Le cas de trois machines autopoïétiques nous intéressera tout particulièrement, trois constellations d’œuvres et de pensées qui débordent le nom propre des « Auteurs » convoqués : Eisenstein et les résistances méthodologiques ; Syberberg et les résistances plastiques ou audiovisuelles (à travers la seule figure du hors-champ) ; Welles et les résistances esth/éthico-politiques. Ainsi, une telle chaîne généalogique nous permettra de mieux mesurer l’efficace de ces résistances, mais sans désir de systématisation ni constitution d’une Théorie de la résistance cinématographique.

Regard sur le projet migratoire et d’intégration et sur le processus identitaire de jeunes réfugiés au Québec

Cette recherche qualitative de type exploratoire tente, à l'aide du discours de jeunes réfugiés, de comprendre de quelle manière leur parcours migratoire contribue à leur projet d'intégration et identitaire, notamment en saisissant leurs perceptions de leur situation actuelle, leurs rapports avec différents réseaux sociaux, l'impact de leur statut identitaire sur leur insertion scolaire, l'impact de leur statut d’immigrant sur les relations intrafamiliales comme sur leurs choix de relations avec les pairs et leur vision de leur futur. De plus, le but de ce mémoire est de poser un regard sur la mise en place de différentes formes de stratégies identitaires au sein de divers réseaux d'appartenance locaux ou transnationaux (école, religion, organismes communautaires, etc.). Afin de mieux comprendre cette réalité, encore peu traitée au Québec, de jeunes réfugiés âgés entre 15 et 21 ans ont été sollicités pour prendre la parole lors de deux entrevues semi-dirigées. Les données résultant des entrevues mettent en évidence une singularité des cas. Malgré tout, quelques tendances semblent ressortir dans le projet migratoire et d’intégration, tels que des trajectoires migratoires empreintes d’événements douloureux, des défis dans le parcours social et scolaire au Québec et une capacité à surmonter l’adversité dans des situations de contraintes répétitives.
