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.

The Feasibility of Using Vocalization Scoring as an Indicator of Poor Welfare During Cattle Slaughter

The article discusses the vocalization of cattle in six slaughter plants and the results indicate that "vocalization scoring could be used as a simple method for detecting welfare problems that need to be corrected".

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.

Socio-demographic factors, smoking, symptoms, morbidities and pulmonary function and quality of life in individuals with a heavy smoking history

Objective: To determine which socio-demographic, exposure, morbidity and symptom variables are associated with health-related quality of life among former and current heavy smokers. Methods: Cross sectional data from 2537 participants were studied. All participants were at ≥2% risk of developing lung cancer within 6 years. Linear and logistic regression models utilizing a multivariable fractional polynomial selection process identified variables associated with health-related quality of life, measured by the EQ-5D. Results: Upstream and downstream associations between smoking cessation and higher health-related quality of life were evident. Significant upstream associations, such as education level and current working status and were explained by the addition of morbidities and symptoms to regression models. Having arthritis, decreased forced expiratory volume in one second, fatigue, poor appetite or dyspnea were most highly and commonly associated with decreased HRQoL. Discussion: Upstream factors such as educational attainment, employment status and smoking cessation should be targeted to prevent decreased health-related quality of life. Practitioners should focus treatment on downstream factors, especially symptoms, to improve health-related quality of life.

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.

L’expérience de dispenser des soins palliatifs à domicile pour des infirmières travaillant dans un contexte non spécialisé

Depuis plusieurs années, la définition des soins palliatifs a été élargie pour inclure toutes les maladies ayant un pronostic réservé. Le Québec s’est doté d’une politique de soins palliatifs dont l’un des principes directeurs est de maintenir les patients dans leur milieu de vie naturel. Alors que présentement environ 10 % de la population nécessitant des soins palliatifs en reçoit, on peut s’attendre à une augmentation des demandes de soins palliatifs à domicile dans les CSSS du Québec. La présente étude a pour but de décrire et comprendre l’expérience de dispenser des soins palliatifs à domicile pour des infirmières travaillant dans un contexte non spécialisé. Une étude qualitative ayant comme perspective disciplinaire la théorie de l’humain-en-devenir de Parse a été réalisée. Des entrevues ont été effectuées auprès de huit infirmières travaillant au maintien à domicile d’un CSSS de la région de Montréal qui font des soins palliatifs dans un contexte non spécialisé. L’analyse des données a été effectuée selon la méthode d’analyse phénoménologique de Giorgi (1997). Les résultats s’articulent autour de trois thèmes qui décrivent l’expérience de dispenser des soins palliatifs à domicile pour des infirmières qui travaillent dans un contexte non spécialisé. Elles accompagnent les patients et leur famille, en s’engageant à donner des soins humains, et développant une relation d’accompagnement avec le patient et ses proches. Elles doivent composer avec les réactions du patient et de sa famille et doivent parfois informer le patient de la progression de son état de santé. De plus, elles se préoccupent de donner des soins de qualité en composant avec la complexité des soins palliatifs à domicile tout en s’assurant de soulager les symptômes des patients et de tenter de développer leur expertise. Finalement, le fait d’être confrontée à la mort permet de cheminer. Ainsi, les infirmières vivent des émotions, reçoivent du soutien, sont touchées personnellement par la mort, éprouvent de la satisfaction envers les soins qu’elles donnent et apprennent personnellement de leur expérience. L’essence du phénomène à l’étude est que lorsque les infirmières font un véritable accompagnement du patient et de sa famille en s’efforçant de donner des soins de qualité, cela crée des conditions permettant qu’un cheminement personnel et professionnel sur la vie et la mort soit effectué par les infirmières.

Should we boycott child labour ?

In high income countries, there is nearly universal popular support for boycotts against products using child labor or punitive sanctions against countries with high levels of child labor. This essay assumes that the reason for this popular support is a concern for the well- being of these child laborers. Consumer boycotts or sanctions should then be viewed by advocates as successful if they make children in low-income countries better off. This essay argues that much of the popular debate on boycotts and sanctions suffers from a failure to consider what children will do if they are not working. To answer this question, the responsible activist or policymaker must understand why children work. While some circumstances of child laborers are so insidious that policies even more aggressive than boycotts may be justified, most of the work performed by children in low income countries reflects the desperateness of their family's poverty. For these cases, if consumer boycotts diminish the earnings power of children, then the incidence of the boycott can be on the poorest of the poor. In this sense, a consumer boycott of products made with child labor can be equivalent to a consumer boycott of poverty relief for both child laborers and their families.

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.

Is microfinance an ethical way to provide financial services to the poor?

Microfinance is increasingly seen as a major development tool. Its promise to help the poor by providing financial services is seen as the major reason for its support. Nevertheless, its ability to effectively reduce poverty is not yet clear, and it generates some unresolved ethical questions. These become even more prominent in the process of commercialization. The impact on poverty is usually measured in financial terms. In this paper, poverty is defined in a broader sense to include deficiency in human and social capital. The article shows that, in this broad sense, microfinance may have negative as well as positive effects on poverty.
