The effectiveness of short-term literacy skills intervention on children at risk of reading and writing difficulties in Tanzania : a study of grade one children with dynamic assessment approach

The aim of the study was to create and evaluate an intervention programme for Tanzanian children from a low-income area who are at risk of reading and writing difficulties. The learning difficulties, including reading and writing difficulties, are likely to be behind many of the common school problems in Tanzania, but they are not well understood, and research is needed. The design of the study included an identification and intervention phase with follow-up. A group based dynamic assessment approach was used in identifying children at risk of difficulties in reading and writing. The same approach was used in the intervention. The study was a randomized experiment with one experimental and two control groups. For the experimental and the control groups, a total of 96 (46 girls and 50 boys) children from grade one were screened out of 301 children from two schools in a low income urban area of Dar-es-Salaam. One third of the children, the experimental group, participated in an intensive training programme in literacy skills for five weeks, six hours per week, aimed at promoting reading and writing ability, while the children in the control groups had a mathematics and art programme. Follow-up was performed five months after the intervention. The intervention programme and the tests were based on the Zambian BASAT (Basic Skill Assessment Tool, Ketonen & Mulenga, 2003), but the content was drawn from the Kiswahili school curriculum in Tanzania. The main components of the training and testing programme were the same, only differing in content. The training process was different from traditional training in Tanzanian schools in that principles of teaching and training in dynamic assessment were followed. Feedback was the cornerstone of the training and the focus was on supporting the children in exploring knowledge and strategies in performing the tasks. The experimental group improved significantly more (p = .000) than the control groups during the intervention from pre-test to follow-up (repeated measures ANOVA). No differences between the control groups were noticed. The effect was significant on all the measures: phonological awareness, reading skills, writing skills and overall literacy skills. A transfer effect on school marks in Kiswahili and English was found. Following a discussion of the results, suggestions for further research and adaptation of the programme are presented.

Spreading depression is facilitated in adult rats previously submitted to short episodes of malnutrition during the lactation period

Lactating rat dams were submitted to short episodes (1, 2 or 3 weeks) of nutritional restriction by receiving the "regional basic diet" (RBD, with 8% protein) of low-income human populations of Northeast Brazil. Their pups were then studied regarding the developmental effects on body and brain weights. When the rats reached adulthood, cortical susceptibility to the phenomenon of spreading depression (SD) was evaluated by performing electrophysiological recordings on the surface of the cerebral cortex. SD was elicited at 20-min intervals by applying 2% KCl for 1 min to a site on the frontal cortex and its occurrence was monitored at 2 sites in the parietal region by recording the electrocorticogram and the slow potential change of SD. When compared to control rats fed a commercial diet with 23% protein, early malnourished rats showed deficits in body and brain weights (10% to 60% and 3% to 15%, respectively), as well as increases in velocity of SD propagation (10% to 20%). These effects were directly related to the duration of maternal dietary restriction, with pups malnourished for 2 or 3 weeks presenting more intense weight and SD changes than those malnourished for 1 week. The effects of 1-week restrictions on SD were less evident in the pups malnourished during the second week of lactation and were more evident in pups receiving the RBD during the third week. The results indicate that short episodes of early malnutrition during the suckling period can affect body and brain development, as well as the cortical susceptibility to SD during adulthood. The data also suggest that the third week of lactation is the period during which the brain is most sensitive to malnutrition, concerning the effects on SD

Changing teachers´ practices in regular schools enrolling children with visual impairment

The number of persons with visual impairment in Tanzania is estimated to over 1.6 million. About half a million of these persons are children aged 7-13. Only about 1% of these children are enrolled in schools. The special schools and units are too few and in most cases they are far away from the children’s homes. More and more regular schools are enrolling children with visual impairment, but the schools lack financial resources, tactile teaching materials and trained special education teachers. Children with visual impairment enrolled in regular schools seldom get enough support and often fail in examinations. The general aim of this study was to contribute to increased knowledge and understanding about how teachers can change their teaching practices and thus facilitate the learning of children with visual impairment included in regular classrooms as they participate in an action research project. The project was conducted in a primary school in a poor rural region with a high frequency of blindness and visual impairment. The school was poorly resourced and the average number of pupils per class was 90. The teachers who participated in the collaborative action research project were the 14 teachers who taught blind or visually impaired pupils in grades 4 and 6, in total 6 pupils. The action research project was conducted during a period of 6 months and was carried out in five cycles. The teachers were actively involved in all the project activities; identifying challenges, planning solutions, producing teaching materials, reflecting on outcomes, collaborating and evaluating. Empirical data was collected with questionnaires, interviews, observations and focus group discussions. The findings of the study show that the teachers managed to change their teaching practices through systematic reflection, analysis and collaboration. The teachers produced a variety of tactile teaching materials, which facilitated the learning of the pupils with visual impairment. The pupils learned better and felt more included in the regular classes. The teachers gained new knowledge and skills. They grew professionally and started to collaborate with each other. The study contributes to new knowledge of how collaborative action research can be conducted in the area of special education in a Tanzanian school context. The study has also relevance to the planning of school-based professional development programs and teacher education programs in Tanzania and in other low-income countries. The results also point at strategies which can promote inclusion of children with disabilities in regular schools.

Effect of a Brazilian regional basic diet on the prevalence of caries in rats

The aim of the present study was to determine the effect of a regional basic diet (RBD) on the prevalence of caries in the molar teeth of rats of both sexes aged 23 days. The animals were divided into six groups of 10 rats each receiving the following diets for 30 and 60 days after weaning: RBD, a cariogenic diet, and a commercial diet. The prevalence and penetration of caries in the molar teeth of the rats was then analyzed. The RBD produced caries in 37.5% of the teeth of animals fed 30 days, and in 83.4% of animals fed 60 days, while the cariogenic diet produced caries in 72.5% and 77.5% of the teeth of animals fed 30 and 60 days, respectively. Rats fed the RBD for 30 days had caries in the enamel in 38% of their teeth, 48% had superficial dentin caries, and 7.5% moderate dentin caries. The effect of the RBD did not differ significantly from that of the cariogenic diet in terms of the presence of caries in rats fed 60 days. The penetration depth of the caries produced by the RBD was the same as that produced by the cariogenic diet. Our results show that the RBD has the same cariogenic potential as the cariogenic diet. Since the RBD is the only option for the low-income population, there should be a study of how to compensate for the cariogenicity of this diet.

Antiretroviral therapy-associated dyslipidemia in patients from a reference center in Brazil

The aim of this study was to determine the impact of antiretroviral therapy on the lipid profile of human immunodeficiency virus (HIV) patients before and after the initiation of highly active antiretroviral therapy (HAART). This was a cross-sectional analysis of patients receiving HAART at a reference center in Belo Horizonte, Brazil, on the basis of medical records from 2002 to 2006. Patients were included if they had at least one lipid test or a clinical or laboratory diagnosis of dyslipidemia/lipodystrophy. Among the 692 patients, 620 met the eligibility criteria. The majority were males (66.5%), middle age (average 39 years), had a low educational level (60.4%), and low income (51.0%). HAART duration ranged from 11 days to 4.6 years, with a mean of 28.6 months (SD = ± 470.19 days). The prevalence of dyslipidemia/lipodystrophy nearly tripled (11.3% pre- and 32.4% post-HAART). Dyslipidemia was associated with older age (P = 0.007), nucleoside reverse transcriptase inhibitor (NRTI) + protease inhibitor (PI) regimens (P = 0.04), NRTI + non-NRTI (NNRTI) regimens (P = 0.026), the use of stavudine (d4T) in any regimen (P = 0.002) or in NRTI-based regimens (P = 0.006), and longer exposure to HAART (P < 0.000). In addition, there was no correlation between dyslipidemia and gender (P = 0.084). Only 2.0% of the patients received treatment for dyslipidemia during the trial. These results show a need for continuous monitoring of patients under antiretroviral therapy, particularly those using NRTI-based regimens, especially when combined with d4T and PIs. Secondly, interventions should be developed to correct metabolic changes.

Application of mathematical models for the prediction of adsorption isotherms in solid mixture for mango powder refreshment

Solid mixtures for refreshment are already totally integrated to the Brazilian consumers' daily routine, because of their quick preparation method, yield and reasonable price - quite lower if compared to 'ready-to-drink' products or products for prompt consumption, what makes them economically more accessible to low-income populations. Within such a context, the aim of this work was to evaluate the physicochemical and mineral composition, as well as the hygroscopic behavior of four different brands of solid mixture for mango refreshment. The BET, GAB, Oswim and Henderson mathematical models were built through the adjustment of experimental data to the isotherms of adsorption. Results from the physiochemical evaluation showed that the solid mixtures for refreshments are considerable sources of ascorbic acid and reductor sugar; and regarding mineral compounds, they are significant sources of calcium, sodium and potassium. It was also verified that the solid mixtures for refreshments of the four studied brands are considered highly hygroscopic.

Solutions to water problems in the bottom of the pyramid market

Solving the water crisis in the developing world is a critical issue. Four billion people in the globe, so called the Base of the Pyramid (BoP) population suffer from inadequate access to safe drinking water, while millions die daily from waterborne diseases and lack of clean water. The BoP people desperately need to obtain a satisfactory access to safe water sources. In order to address the issue, this research has been carried out. To provide holistic consideration to the matter, comprehensive exploration of various causes of the water crisis and its impacts in developing countries were discussed. Then, various viable and relevant solutions to the problem have been thoroughly scrutinized, including scientific, rational, practical and speculative approaches, examination of existing methods, technologies and products at the BoP water market. The role of clean water to the sustainable development was specifically featured. The paper also has studied social and economic factors, actors and circumstances which affect the market development of clean water technologies in the BoP. Possibilities and potentials of successful business between foreign water enterprises and BoP consumers were considered, while primary obstacles are deliberated on, with suggestion of the ways to tackle them. Technologies and products which are needed by the poor must be affordable, sustainable and of an appropriate quality. The crucial question of technology transfer was soundly discussed with pointing out main hindrances on the way of its implementation between the developed and developing world. The means to overcome these barriers were properly observed as well. To explore to some extent the possibility and feasibility of technology transfer from Finland to the BoP sector, 3 case study analyses have been implemented. Personal discussions in form of interviews were conducted at Kemira, Outotec and Fenno Water, Finnish water treatment and supply enterprises. The results of the interviews shed light on the specific practical matters, actual obstacles and potential solutions of the technology transfer from Finland to low-income countries.

The role of molecular, clinical and socioeconomic factors in the long-term survival of axillary node negative breast cancer patients

The overall objective of this study was to investigate factors associated with long-term survival in axillary node negative (ANN) breast cancer patients. Clinical and biological factors included stage, histopathologic grade, p53 mutation, Her-2/neu amplification, estrogen receptor status (ER), progesterone receptor status (PR) and vascular invasion. Census derived socioeconomic (SES) indicators included median individual and household income, proportions of university educated individuals, housing type, "incidence" of low income and an indicator of living in an affluent neighbourhood. The effects of these measures on breast cancer-specific survival and competing cause survival were investigated. A cohort study examining survival among axillary node negative (ANN) breast cancer patients in the greater Toronto area commenced in 1 989. Patients were followed up until death, lost-to-follow up or study termination in 2004. Data were collected from several sources measuring patient demographics, clinical factors, treatment, recurrence of disease and survival. Census level SES data were collected using census geo-coding of patient addresses' at the time of diagnosis. Additional survival data were acquired from the Ontario Cancer Registry to enhance and extend the observation period of the study. Survival patterns were examined using KaplanMeier and life table procedures. Associations were examined using log-rank and Wilcoxon tests of univariate significance. Multivariate survival analyses were perfonned using Cox proportional hazards models. Analyses were stratified into less than and greater than 5 year survival periods to observe whether known markers of short-tenn survival were also associated with reductions in long-tenn survival among breast cancer patients. The 15 year survival probabilities in this cohort were: for breast cancerspecific survival 0.88, competing causes survival 0.89 and for overall survival 0.78. Estrogen receptor (ER) and progesterone receptor (PR) status (Hazard Ratio (HR) ERIPR- versus ER+/PR+, 8.15,95% CI, 4.74, 14.00), p53 mutation (HR, 3.88, 95% CI, 2.00, 7.53) and Her-2 amplification (HR, 2.66, 95% CI, 1.36, 5.19) were associated with significant reductions in short-tenn breast cancer-specific survival «5 years following diagnosis), however, not with long-term survival in univariate analyses. Stage, histopathologic grade and ERiPR status were the clinicallbiologieal factors that were associated with short-term breast cancer specific survival in multivariate results. Living in an affluent neighbourhood (top quintile of median household income compared to the rest of the population) was associated with the largest significant increase in long-tenn breast cancer-specific survival after adjustment for stage, histopathologic grade and treatment (HR, 0.36, 95% CI, 0.12, 0.89).

"Welcome to my life" : the experiences of single mothers who are the recipients of multiple state provided benefits

Abstract This research takes the lens of social reproduction as a starting point for an examination of the effects of recent social welfare reforms on the lives o.fsingle mothers. As the cumulative effects o.f diminishing state provided benefits take hold, tensions are heightened as single mothers internalize the insecurity of earning an income in 11 capitalist labour market, while trying to carry out all that is involved in social reproduction with inadequate means of survival. Through interviewing single mothers who are the recipients of mUltiple state provided benefits (social assistance, student loans, subsidized housing and subsidized childcare), this thesis illuminates the cOl1linued regulation of women in an effort to assure that social reproduction is occurring at the lowest cost possible. State provided benefits are set lip in such a way that it is near impossible for single mothers to make ends meet without entering the labour force or entering into co-residential relationships. This push towards the labour force and/or marriage via punitive welfare policies illuminates the devaluation of the labour that is done at home. Through interviewing 5 single mothers, I will demonstrate the extensive labour that goes into maintaining their households. In addition .J case managers are interviewed. The employees of social assistance, subsidized hOllsing, subsidized childcare and student loans, have much agency in deeming who is worthy of receiving benefits. The employees of these agencies have the ability to make these women's lives easier or more complicated by how the workers interpret the policy regulations. Social policies are of paramount importance in the quest for women's equality and thus have consequences for how women's daily lives are organized. The rules and regulations that govern the individual policies are complex and bureaucratic and have implications for the ways in which women must organize their lives in order to survive. The shifts in social policy have been guided by neo-liberal assumptions with a focus on individual responsibility and a market-modeled welfare state. The caring work that is involved in raising children to be productive in a capitalist society is ignored or devalued in current policies. The emphasis in each polic.:v is on getting women who receive benefits into the paid work force, with little facilitation or investment into the caring work these women do on a daily basis that in turn supports capitalism. Policies, such as social assistance, subsidized housing, subsidized childcare and student loans, are set up in such a way that ignores the reality of women's day-to-day lives and devalues the necessary work done at home. It takes an abundance of labour and strategizing for women to seek out necessary means of survival, labour that is amplified when a woman is dealing with mUltiple slate provided benefits.

The impact of social welfare reform and workfare on lone-parent female headed households in the Niagara Region

This thesis explores the impact of recent social welfare reforms on the lives of social assistance recipients. The focus is on single mothers who are dependent on social assistance in a small city in southern Ontario. This detailed examination is complemented with existing case studies in Canada, the United States and New Zealand, as well as aggregate data on poverty in Canada. Participants for the research study were recruited by flyer distribution and referral. Following recruitment, selected participants were scheduled for a tape- recorded interview. The final sample population consists of eight single mothers on social assistance and/or workfare participants. This information is supplemented with interviews from two Ontario Works caseworkers and two Women's Advocates from a local crisis housing organization. This research project is guided by a socialist feminist framework. Evidence from interview participants suggest that single mothers continue to struggle in terms of meeting basic needs, such as food, clothing and medications. Housing for low-income families is a concern expressed by the participants as well as by Women's Advocates who operate within the region. In addition, subsidized housing continues to be problematic in terms of both safety and availability. Recent social welfare refonns (reductions in welfare income and introduction of workfare features) have intensified the economic and social marginalization of these women. Participants, for example, voice concerns about valuing self-evaluation in their Ontario Works and workfare activities. Considerable evidence from interview participants suggest that single mothers remain economically marginalized.

A Quantitative Study of Social Capital Components, Self-Reported Health Status and Social Determinants of Health

This quantitative descriptive co-relational study used telephone survey interviews and stratified random sampling to collect data related to Social Capital (SC) and its components (trust and safety, reciprocity, civic engagement and collective action) and selected determinants of health variables in Niagara Region, Canada. Among the four components of social capital, trust and safety levels were highest among all participants (m=5.42, SD=1.0), with community engagement yielding the lowest mean score for the sample (m=1.93, SD=.8). Reciprocity had the strongest association with all other components of SC (r=0.51). Those most likely to report low levels of SC and health were unattached and low-income females. Males were more likely to report higher trust and safety levels and higher levels of self-rated health. In this study, a linear relationship between self-reported health status and SC was not found. Marital and employment status were associated with differences in mean scores of SC and self-reported health.

Effets d’un programme prénatal de groupe adressé aux couples parentaux pour prévenir la dépression postnatale des femmes de classes moyenne et défavorisée habitant en Catalogne Nord et en France Sud

La dépression postnatale (DP) est un problème de santé publique très fréquent dans différentes cultures (Affonso et al, 2000). En effet, entre 10% à 15% des mères souffrent d’une symptomatogie dépressive ainsi que l’indiquent Gorman et al. (2004). La prévention de la DP est l’objectif de différents programmes prénatals et postnatals (Dennis, 2005; Lumley et al, 2004). Certains auteurs notent qu’il est difficile d’avoir accès aux femmes à risque après la naissance (Evins et al, 2000; Georgiopoulos et al, 2001). Mais, les femmes fréquentent les centres de santé pendant la grossesse et il est possible d’identifier les cas à risque à partir des symptômes prénataux dépressifs ou somatiques (Riguetti-Veltema et al, 2006); d’autant plus qu’un grand nombre de facteurs de risque de la DP sont présents pendant la grossesse (O’Hara et Gorman, 2004). C’est pourquoi cette étude fut initiée pendant le premier trimestre de la grossesse à partir d’une détection précoce du risque de DP chez n= 529 femmes de classes moyenne et défavorisée, et, cela, au moyen d’un questionnaire validé utilisé à l’aide d’une entrevue. L’étude s’est effectuée dans trois villes : Barcelone, Figueres, et Béziers au cours des années 2003 à 2005. Objectif général : La présente étude vise à évaluer les effets d’un programme prénatal de groupes de rencontre appliqué dans la présente étude chez des couples de classe socioéconomique non favorisée dont les femmes sont considérées comme à risque de dépression postnatale. L’objectif spécifique est de comparer deux groupes de femmes (un groupe expérimental et un groupe témoin) par rapport aux effets du programme prénatal sur les symptômes de dépression postnatale mesurés à partir de la 4ème semaine après l’accouchement avec l’échelle EPDS. Hypothèse: Les femmes participant au programme prénatal de groupe adressé aux couples parentaux, composé de 10 séances hebdomadaires et inspiré d’une orientation psychosomatique présenteront, au moins, un taux de 6% inférieur de cas à risque de dépression postnatale que les femmes qui ne participent pas, et cela, une fois évaluées avec l’échelle EPDS (≥12) 4 semaines après leur accouchement. Matériel et méthode: La présente étude évaluative est basée sur un essai clinique randomisé et longitudinal; il s’étend de la première ou deuxième visite d’échographie pendant la grossesse à un moment situé entre la 4ème et la 12ème semaine postnatale. Les participants à l’étude sont des femmes de classes moyenne et défavorisée identifiées à risque de DP et leur conjoint. Toutes les femmes répondant aux critères d’inclusion à la période du recrutement ont effectué une entrevue de sélection le jour de leur échographie prénatale à l’hôpital (n=529). Seules les femmes indiquant un risque de DP furent sélectionnées (n= 184). Par la suite, elles furent distribuées de manière aléatoire dans deux groupes: expérimental (n=92) et témoin (n=92), au moyen d’un programme informatique appliqué par un statisticien considérant le risque de DP selon le questionnaire validé par Riguetti-Veltema et al. (2006) appliqué à l’aide d’une entrevue. Le programme expérimental consistait en dix séances hebdomadaires de groupe, de deux heures et vingt minutes de durée ; un appel téléphonique entre séances a permis d’assurer la continuité de la participation des sujets. Le groupe témoin a eu accès aux soins habituels. Le programme expérimental commençait à la fin du deuxième trimestre de grossesse et fut appliqué par un médecin et des sages-femmes spécialement préparées au préalable; elles ont dirigé les séances prénatales avec une approche psychosomatique. Les variables associées à la DP (non psychotique) comme la symptomatologie dépressive, le soutien social, le stress et la relation de couple ont été évaluées avant et après la naissance (pré-test/post-test) chez toutes les femmes participantes des deux groupes (GE et GC) utilisant : l’échelle EPDS (Cox et al,1987), le Functional Social Support Questionnaire (Broadhead et al, 1988), l’évaluation du stress de Holmes et Rahe (1967) et, l’échelle d’ajustement dyadique de Spanier (1976). La collecte des données prénatales a eu lieu à l’hôpital, les femmes recevaient les questionnaires à la fin de l’entrevue, les complétaient à la maison et les retournaient au rendez-vous suivant. Les données postnatales ont été envoyées par les femmes utilisant la poste locale. Résultats: Une fois évalués les symptômes dépressifs postnatals avec l’échelle EPDS entre la 4ème et la 12ème semaine postnatale et considérant le risque de DP au point de césure ≥ 12 de l’échelle, le pourcentage de femmes à risque de DP est de 39,34%; globalement, les femmes étudiées présentent un taux élevé de symptomatologie dépressive. Les groupes étant comparables sur toutes les variables prénatales, notons une différence dans l’évaluation postnatale de l’EPDS (≥12) de 11,2% entre le groupe C et le groupe E (45,5% et 34,3%). Et la différence finale entre les moyennes de l’EPDS postnatal est de 1,76 ( =11,10 ±6,05 dans le groupe C et =9,34 ±5,17 dans le groupe E) ; cette différence s’aproche de la limite de la signification (p=0,08). Ceci est dû à un certain nombre de facteurs dont le faible nombre de questionnaires bien complétés à la fin de l’étude. Les femmes du groupe expérimental présentent une diminution significative des symptômes dépressifs (t=2,50 / P= 0,01) comparativement au pré-test et indiquant une amélioration au contraire du groupe témoin sans changement. Les analyses de régression et de covariance montrent que le soutien social postnatal, les symptômes dépressifs prénatals et le stress postnatal ont une relation significative avec les symptômes dépressifs postnatals (P<0,0001 ; P=0.003; P=0.004). La relation du couple n’a pas eu d’impact sur le risque de DP dans la présente étude. Par contre, on constate d’autres résultats secondaires significatifs: moins de naissances prématurées, plus d’accouchements physiologiques et un plus faible taux de somatisations non spécifiques chez les mères du groupe expérimental. Recommandations: Les résultats obtenus nous suggèrent la considération des aspects suivants: 1) il faudrait appliquer les mesures pour détecter le risque de DP à la période prénatale au moment des visites d’échographie dont presque toutes les femmes sont atteignables; il est possible d’utiliser à ce moment un questionnaire de détection validé car, son efficacité semble démontrée; 2) il faudrait intervenir auprès des femmes identifiées à risque à la période prénatale à condition de prolonger le programme préventif après la naissance, tel qu’indiqué par d’autres études et par la demande fréquente des femmes évaluées. L’intervention prénatale de groupe n’est pas suffisante pour éviter le risque de DP chez la totalité des femmes. C’est pourquoi une troisième recommandation consisterait à : 3) ajouter des interventions individuelles pour les cas les plus graves et 4) il paraît nécessaire d’augmenter le soutien social chez des femmes défavorisées vulnérables car cette variable s’est révélée très liée au risque de dépression postnatale.

Les sources d'incohérences des initiatives de financement du logement social au Nicaragua

Le Nicaragua connaît un déficit en logement très préoccupant. Celui-ci est du en grande partie à l’incapacité du secteur financier à satisfaire la demande des familles à faible revenu. De nombreuses initiatives ont été mises en place par des organismes provenant des trois sphères sociétales pour pallier ce problème. Certains l’ont fait avec succès d’autres sans. Aujourd’hui bien que ces initiatives aient comme objectif de répondre au problème existant, le déficit continu de se creuser. Ce mémoire propose une analyse des causes du problème afin de comprendre pourquoi les initiatives mises en place ne fonctionnent pas comme elles le devraient. Il met en avant le manque de coordination qui existe enter les acteurs et démontre que l’ensemble du secteur fonctionne selon une organisation « en silo » révélatrice d’un manque de cohérence des politiques de financement du logement. Enfin il analyse les origines possibles d’une telle organisation et des incohérences politiques qui l’ont amenée. Par cette analyse, il tente de déterminer la part de responsabilité relative imputable à l’État nicaraguayen et à l’Aide Publique au Développement qui est la principale source de fonds de tous ces programmes.

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.

Liens entre défavorisation extrême chez des enfants à la maternelle et engagement en classe en 3e année du primaire

L’objectif de cette étude est de vérifier s’il existe un lien entre les conditions de défavorisation extrême associées à la pauvreté familiale telles que vécues par l’enfant en maternelle et son engagement en classe en 3e année du primaire. Pour ce faire, nous avons analysé des données portant sur un groupe de 341 enfants provenant des régions les plus défavorisées de Montréal à partir des observations rapportées par leur enseignant. Plusieurs régressions multiples ont permis de mettre en évidence des indicateurs sur l’engagement en classe, soit la concentration, la persistance et l’autonomie des participants avec quatre indicateurs liés à la défavorisation extrême soit la faim, les retards à l’école, l’habillement inadéquat et les signes de fatigue. Les résultats de cette étude ont montré que chacun de ces indicateurs pouvait indépendamment contribuer à l’engagement en classe, mais, que deux indicateurs ont un pouvoir prédictif supérieur et fiable, soit le retard en classe et les signes de fatigue. D’autres recherches plus poussées étaient les résultats de la présente étude et suggèrent comment une intervention précoce des enseignants, au début du primaire, pourrait encourager l’engagement en classe d’enfant provenant d’une population défavorisée urbaine.
