Problématique : Plusieurs expositions résidentielles ont été associées à la prévalence de l’asthme. Toutefois, peu d’études populationnelles ont examiné la relation entre ces facteurs et un asthme mal maîtrisé chez l’enfant. Objectif : Évaluer les facteurs environnementaux résidentiels associés à un asthme mal maîtrisé chez les enfants montréalais âgés de 6 mois à 12 ans. Méthodes : Les données sont tirées d’une enquête transversale menée en 2006 sur la santé respiratoire d’enfants montréalais âgés de 6 mois à 12 ans (n=7980). La maîtrise de l’asthme a été évaluée chez les enfants avec un asthme actif au cours de l’année précédent l’enquête (n=980) selon des critères recommandés par les lignes directrices canadiennes sur l’asthme. Les rapports de prévalence (RP) et les intervalles de confiance (IC) à 95 % caractérisant l’association entre les facteurs environnementaux, incluant la présence d’allergènes, d’irritants, d’humidité et de moisissures, et le risque d’un asthme mal maîtrisé ont été estimés à l’aide de modèles de régression log-binomiale. Les sujets avec une maîtrise acceptable de l’asthme ont été comparés à ceux dont la maladie était mal maîtrisée. Résultats : Des 980 enfants avec un asthme actif au cours de l’année précédant l’enquête, 36 % ont rencontré au moins un des critères des lignes directrices canadiennes suggérant un asthme mal maîtrisé. Les caractéristiques de la population associées à un asthme mal maîtrisé sont : un plus jeune âge, des antécédents d’atopie parentale, une faible scolarisation de la mère, une mère d’origine étrangère et le statut de locataire. Après ajustement pour l’âge de l’enfant, l’atopie parentale et l’exposition à la fumée de tabac au domicile, une intensité de trafic élevée à proximité du domicile (RP, 1,35; IC 95 %, 1,00-1,81) et la localisation au sous-sol de la chambre de l’enfant ou de sa résidence (RP 1,30; IC 95 %, 1,01-1,66) étaient associées à un risque accru d’asthme mal maîtrisé. Conclusions : Une maîtrise sous-optimale de l’asthme semble être associée à l’exposition au trafic routier et à des conditions d’humidité excessive et probablement de moisissures. Cette dernière exposition étant plus fréquente, elle a probablement un plus grand impact en matière de santé publique. / Background: Home environmental exposures may impede asthma control in children. However, few population-based studies have investigated this relationship. Objective: Identify environmental home exposures associated with poor asthma control among asthmatic children less than 12 years of age in Montreal. Methods: This cross-sectional population-based study used data from a respiratory health survey of Montreal children aged 6 months to 12 years conducted in 2006 (n=7,980). Asthma control was assessed among those with active asthma in the year prior to the survey (n=980) using an adaptation of the Canadian asthma consensus report clinical parameters. Using log-binomial regression models, prevalence ratios (PR) with 95 % confidence intervals (CI) were estimated to explore the relationship between inadequate control of asthma and environmental home exposures, including allergens, irritants, mold and dampness indicators. Subjects with acceptable asthma control were compared with those with inadequate disease control. Results: Of 980 children with active asthma in the year prior to the survey, 36 % met at least one of the five criteria outlined in the Canadian asthma guidelines as to poor control of their disease. The population’s characteristics found to be related with a lack of asthma control were: younger age, a history of parental atopy, low maternal education level, foreign-born mothers and tenant occupancy. After adjustments for the child’s age, parental atopy and tobacco smoke exposure at home, children living along high-traffic density streets (PR, 1.35; 95 % CI, 1.00-1.81) and those with their bedroom or residence in the basement (PR, 1.30; 95 % CI, 1.01-1.66) were found to be at increased risk of poor asthma control. Conclusions: Suboptimal asthma control appears to be mostly associated with traffic, along with mold and moisture conditions, the latter being a more frequent exposure and therefore having a greater public health impact.

The purpose of this study is to evaluate teachers attitudes towards reading homework and their thoughts regarding feedback. The study will also be looking at what type of support pupils are given regarding their reading homework and homework in general. This study will also evaluate the teachers’ thoughts on equality in connection with the pupils varying home conditions that affect how much support and help they receive with their reading homework.  I collected data for this study by using survey and interview methods. These two methods complement each other as they give a wide and in-depth-look at the questions in this study.  The results from this study show teachers attitudes towards reading homework as well as different forms of feedback that can be given. It also highlights teachers experiences when it comes to their schools homework support practice relating to reading and other types of homework that their pupils are given. Also included are the teachers’ thoughts regarding equality when related to pupils varying home conditions that affect help and support related to reading homework. The word that best describes teachers’ opinions on the current equivalent schooling is unfairness. / Syftet med studien är att undersöka lärares inställning till läsläxa samt deras tankar angående återkoppling och skolans stöd till eleverna med deras läsläxa och läxor i övrigt. Studien syftar även till att undersöka lärares tankar gällande likvärdighet kopplat till elevers olika förutsättningar till stöd och hjälp i hemmet med deras läsläxa.  Studiens tillvägagångssätt gällande datainsamling har skett via två metoder, enkät samt intervju. Datainsamlingsmetoderna kompletterar varandra och ger en bredd samt ett djup i frågorna.  Resultatet i studien redovisar lärares inställning till läsläxa samt varianter på återkoppling till den. Studiens resultat lyfter även lärares upplevelser om skolans stöd med läsläxa och övriga läxor till sina elever samt lärares tankar angående likvärdighet kopplat till elevers olika förutsättningar i hemmiljön gällande stöd och hjälp med läsläxa. Ordet som beskriver lärarnas åsikt gällande likvärdighetstanken är orättvisa.

Academic achievement is deemed a significant indicator for a successful future. Cognitive ability, home environment, and metacognition are among the many factors research has posited to contribute to academic achievement and later success (Alloway & Alloway, 2010; Bradley & Caldwell, 1984, Veenman, Wilhelm, & Beishuizen, 2004). The present study examines the relation between cognitive ability (working memory (WM) and nonverbal ability), metacognitive awareness, implicit theories of IQ, home environment (socioeconomic status (SES), home life, and parental involvement in homework), and learning outcomes (grades) in two distinct sample populations. The study used a sample of 11-15-year-olds and their parents from two high schools in Carriacou, Grenada (n=50) and Lakeshore Middle School in Florida (n=38). A stepwise regression revealed that cognitive ability, implicit theories of IQ, and home environment predicted overall grades of the Grenada sample. Several differences between the two cultures emerged including what predicted their implicit theories of IQ. The present study will benefit the educational community, as the findings could provide new insight into how students’ cognitive ability, implicit theories of IQ, and home life influence learning outcomes in a developed and developing population. The practical implications suggest more effective culturally responsive educational programs for students based on their learning style and learning needs. The present study has significance with reference to Grenada, in that because of little to no research available investigating this topic it will provide a basis for subsequent research to occur.

Det finns fortfarande för många hushåll i Sverige som använder mest glödljus för belysning, i form av glödlampor eller halogenlampor. Detta orsakar en väsentlig del av det onödiga överskott av koldioxidutsläpp som är en av orsakerna till den globala uppvärmningen. Därför avser detta examensarbete att försöka skapa en grönare miljö genom att studera och uppmärksamma faktorer som påverkar val av ljuskällor i belysningssammanhang. Syftet med examensarbetet är att få en ökad förståelse för hur LED-ljuset upplevs i hemmiljö. Arbetet ska visa hur LED-ljuskällans nuvarande kvalité bedöms utifrån individuella rumsupplevelser samt om ytterligare kvalitetsförbättringar behövs. Detta görs för att kunna vända allmänhetens inställning i en mer positiv riktning gentemot LED, vilket kan bidra till en mer ekologiskt hållbar miljö. För att undersöka hur LED fungerar i hemmiljö genomfördes en experimentell studie med syfte att besvara följande frågor: hur upplevs LED-ljusets kvalité jämfört med halogenljusets, hur tror man att det egna välmåendet påverkas av halogenljus respektive LED-ljus, hur påverkas rumsupplevelsen och rumskaraktären om halogenljus ersätts med LED-ljus och finns det några skillnader mellan ljusdesigners och icke ljusdesigners upplevelse av halogenljus och LED-ljus i hemmiljö? Det byggdes upp två likadana försöksrum som hade samma förutsättningar både storleksmässigt, inredningsmässigt och belysningsmässigt. Den enda skillnaden var de installerade ljuskällorna, då det användes halogenlampor i det ena rummet och LED-lampor i det andra rummet. En enkätundersökning genomfördes, resultatet analyserades och en utförlig rumsanalys gjordes. Resultatet visade att ljuset, oavsett ljuskälla, påverkade deltagarnas välmående och rumsupplevelse på olika sätt, beroende på vilken yrkesgrupp de tillhörde. Det visade sig också att skillnaden i ljuskvalitén mellan halogenljus och LED-ljus inte längre är omfattande. Dagens LED-lampor utvecklas alltså positivt och är redan en värdig ersättare till glöd- och halogenlampor. / There are still too many households in Sweden that use mostly incandescent light for lighting, using incandescent or halogen bulbs. This causes a substantial part of the unnecessary surplus of carbon-dioxide that is one of the reasons for global warming. Therefore, this degree project aims to promote a greener environment by studying and paying attention to factors that have an influence in the lighting context. The purpose of this degree project is to gain a better understanding of how the LED light is experienced in a home environment. The work will show how LED light source's current quality is evaluated based on individual room experiences, and if additional quality improvements are needed. The objective is to turn the public's attitude in a more positive direction where LED can contribute to a more ecologically sustainable environment. To investigate how LEDs are perceived in home environments an experimental study was performed which was based on the following research questions: How is LED light quality experienced compared to halogen light, how is personal wellbeing perceived in relationship to halogen and LED light, how are room experience and room character affected if halogen light is replaced by LED light in a home environment and are there any differences in these experiences between lighting designers and non lighting designers? Two identical test-rooms were used. They were identical in size, interior design and lighting design. Halogen bulbs were used in one room and LED lights were used in the other room. A survey was used to get answers to the questions above. The results have been analyzed and detailed room analysis was also made. The results showed that the light, regardless of light-source, influenced the participant's well-being and their room experience in different ways, depending on the occupational group they belonged to. It was also found that the difference in quality of light between halogen light and LED light is no longer significant. The presently available LED lights are improving and are worthy replacements for incandescent and halogen lamps.

O objetivo desta pesquisa, de delineamento quase-experimental, foi verificar os efeitos da intervenção motora em três diferentes contextos - abordagens individual no domicílio (ID), individual na creche (IC) e grupo na creche (GC) - no desenvolvimento motor e social de crianças com atrasos motores, na faixa etária entre 06 e 18 meses de idade, residentes em bairros da periferia do município de Porto Alegre/RS, assistidas por unidades básicas de saúde vinculadas ao Hospital Moinhos de Vento e amparadas por creches comunitárias conveniadas com a prefeitura. Descrições do comportamento de cada criança antes e após o período interventivo e características do seu ambiente domiciliar foram associadas ao seu desempenho motor. A amostra desta pesquisa foi voluntária, selecionada de forma não-probabilística e intencional. A partir de uma população de 96 crianças avaliadas, 40 apresentaram percentil de desempenho motor abaixo de 25%, e destas, 32 crianças finalizaram as 24 sessões de intervenção motora, no período de 12 semanas. Cada grupo interventivo ficou assim distribuído: ID n=12, IC n=7 e GC n=13. Os instrumentos utilizados neste estudo foram a escala comportamental das Bayley Scales of Infant Development II (BSID-II), a Alberta Infant Motor Scale (AIMS) e o questionário Affordances in the Home Environment for Motor Development Self-Report (AHEMD-SR). O programa de intervenção, realizado entre maio e novembro de 2007, foi constituído por atividades lúdicas com o intuito de alongar e adequar o tônus muscular, estimular o acompanhamento visual e auditivo, controlar as posturas em diferentes circunstâncias, manipular objetos e deslocar-se, a fim de oportunizar às crianças a experimentação de novas condições de movimento e a superação de desafios. Todos os dados coletados foram analisados através do programa estatístico SPSS para Windows, versão 13.0. Para estas análises, o nível de significância adotado foi p≤0,05. O resultado do Teste de Normalidade Shapiro-Wilk, aplicado nos escores de desempenho motor na primeira avaliação, sugere que os dados não se apresentaram normalmente distribuídos (p=0,04). Desta forma, foram utilizados testes não-paramétricos. Na comparação das variáveis nos dois períodos avaliativos (pré e pós intervenção), o Teste de Kruskal-Wallis foi utilizado e, na presença de diferença significativa entre os grupos, o Teste Complementar de Mann-Whitney. Na comparação do percentil de desempenho motor de cada grupo ao longo do tempo (antes e após o período interventivo), com a finalidade de verificar o efeito do programa de intervenção motora, aplicou-se o Teste de Wilcoxon. Na descrição dos resultados, utilizou-se a mediana e a amplitude interquartílica (P25-P75). Os resultados evidenciaram mudanças significativas no desempenho motor nos três diferentes grupos (ID p=0,014, IC p=0,028 e GC p=0,005), e suportam a hipótese de que crianças com atrasos motores participantes do programa de intervenção apresentariam incremento no seu desempenho motor quando comparadas à avaliação inicial. As observações do comportamento das crianças desta amostra corroboram o pressuposto de que elas apresentariam, após a intervenção, incremento no seu desempenho social. A análise da variação dos escores totais de oportunidades de estimulação no lar, utilizando-se o Teste Qui-quadrado de McNemar, não evidenciou mudanças estatisticamente significativas nos diferentes grupos do estudo (p=1,000), rejeitando o pressuposto de que o programa de intervenção teria impacto positivo no contexto familiar, favorecendo mudanças significativas de engajamento nas diferentes atividades infantis rotineiras, bem como nas atitudes familiares frente às restrições destas crianças. Estratégias interventivas vinculadas ao contexto do desenvolvimento de crianças com atrasos motores promovem incremento em seu desempenho motor e social, e a identificação da criança de risco permite o acompanhamento precoce e a compreensão de suas necessidades. Estes achados sugerem a necessidade de programas de intervenção para famílias de baixa renda que otimizem as oportunidades de estimulação também no ambiente domiciliar. / The purpose of the present study, of quasi-experimental design, was to verify the effects of a motor intervention in three different contexts - individual at home (ID), individual at the daycare (IC) and in groups at the daycare (GC) - on motor and social development of children with motor delays, between 06 and 18 month-old, living in the suburbs of the city of Porto Alegre/RS, who were assisted by basic units of health affiliated to Moinhos de Vento Hospital and supported by communitarian daycare centers linked to the City Hall. Descriptions of the behavior of each child before and after the interventive period and characteristics of their home environment were associated to their motor performance. The sample for this research was voluntary, selected in a non probabilistic and intentional form. From a total of 96 assessed children, 40 presented percentile ranking below 25%, and, of those, 32 finished the 24 sessions of motor intervention, in a period of 12 weeks. Each interventive group was thus distributed: ID n=12, IC n=7 and GC n=13. The instruments used in this study were the behavior rating scale of Bayley Scales of Infant Development II (BSID-II), the Alberta Infant Motor Scale (AIMS) and the inventory Affordances in the Home Environment for Motor Development Self-Report (AHEMD-SR). The intervention program, carried out between May and November of 2007, was composed by playful activities which were planned to stretch and adjust the muscular tonus, to stimulate visual and auditory accompaniment, to control postures in different circumstances, to manipulate objects and to move around, in order to allow the children to experiment with new movement conditions and the overcoming of challenges. All the collected data were analyzed through the SPSS statistical program for Windows, version 13.0. In all the analyses, it was considered a significance level of p≤0,05. The result of the Shapiro-Wilk Normality Test, applied in the scores of motor performance in the first evaluation, suggested that the data was a non-normal distribution (p=0,04). Thus, non-parametric tests were used. In the comparison of the variables in the two evaluative periods (pre and post intervention), the Kruskal-Wallis’ Test was used and, when this test demonstrated significant differences between groups, the Mann-Whitney’s U Test was used. In the comparison of the percentile of motor performance of each group throughout time (before and after the interventive period), intending to verify the effect of the motor intervention program, the Wilcoxon Test was applied. In the description of the results, the median and the interquartilic range were used (P25-P75). The results showed significant improvement in the motor performance in the three different groups (ID p=0,014, IC p=0,028 and GC p=0,005), supporting the conviction that children with motor delays taking part in the intervention program would present increase in their motor performance when compared to the initial evaluation. The observations of children’s behavior from this sample corroborate with the conviction that they would show, after the intervention, increase in their social performance. The analysis of the variation of the total scores for opportunities of home stimulation, using McNemar Test, did not show evidence of significant statistical changes in the different study groups (p=1,000), rejecting the conviction that the intervention program would have a positive impact in the home environment, favoring significant changes of engagement in different infant routine activities, as well as in a shift in family attitude towards these children’s restrictions. Interventive strategies tied to the context of development of children with motor delays promote increase in their motor and social performance, and the identification of a risk child allows early accompaniment and the understanding of their necessities. These findings suggest the need of programs of intervention for low income families who also optimize the chances of stimulation in the home environment.

The primary aim of this research was to determine whether the home environment of secondary school children has an influence on their academic performance. A literature study was done where the major aspects of the home environment were identified: family lifestyle, parental involvement and attitude, physical living conditions. An analysis of academic performance and the factors affecting it was done. A measuring instrument was developed in order to measure the home environment in terms of being positive or negative. The results of the empirical research indicated that while home environment and age do play a significant role in the academic performance of secondary school children, gender, maternal employment, and whether the child lives permanently with both parents, did not. The educational implications of the findings and the teacher's role are discussed, and guidelines regarding the development of a home environment conducive to better academic performance are given. / Psychology of Education / M.

These findings suggest the need of programs of intervention for low income families who also optimize the chances of stimulation in the home environment.

O objetivo desta pesquisa, de delineamento quase-experimental, foi verificar os efeitos da intervenção motora em três diferentes contextos - abordagens individual no domicílio (ID), individual na creche (IC) e grupo na creche (GC) - no desenvolvimento motor e social de crianças com atrasos motores, na faixa etária entre 06 e 18 meses de idade, residentes em bairros da periferia do município de Porto Alegre/RS, assistidas por unidades básicas de saúde vinculadas ao Hospital Moinhos de Vento e amparadas por creches comunitárias conveniadas com a prefeitura. Descrições do comportamento de cada criança antes e após o período interventivo e características do seu ambiente domiciliar foram associadas ao seu desempenho motor. A amostra desta pesquisa foi voluntária, selecionada de forma não-probabilística e intencional. A partir de uma população de 96 crianças avaliadas, 40 apresentaram percentil de desempenho motor abaixo de 25%, e destas, 32 crianças finalizaram as 24 sessões de intervenção motora, no período de 12 semanas. Cada grupo interventivo ficou assim distribuído: ID n=12, IC n=7 e GC n=13. Os instrumentos utilizados neste estudo foram a escala comportamental das Bayley Scales of Infant Development II (BSID-II), a Alberta Infant Motor Scale (AIMS) e o questionário Affordances in the Home Environment for Motor Development Self-Report (AHEMD-SR). O programa de intervenção, realizado entre maio e novembro de 2007, foi constituído por atividades lúdicas com o intuito de alongar e adequar o tônus muscular, estimular o acompanhamento visual e auditivo, controlar as posturas em diferentes circunstâncias, manipular objetos e deslocar-se, a fim de oportunizar às crianças a experimentação de novas condições de movimento e a superação de desafios. Todos os dados coletados foram analisados através do programa estatístico SPSS para Windows, versão 13.0. Para estas análises, o nível de significância adotado foi p≤0,05. O resultado do Teste de Normalidade Shapiro-Wilk, aplicado nos escores de desempenho motor na primeira avaliação, sugere que os dados não se apresentaram normalmente distribuídos (p=0,04). Desta forma, foram utilizados testes não-paramétricos. Na comparação das variáveis nos dois períodos avaliativos (pré e pós intervenção), o Teste de Kruskal-Wallis foi utilizado e, na presença de diferença significativa entre os grupos, o Teste Complementar de Mann-Whitney. Na comparação do percentil de desempenho motor de cada grupo ao longo do tempo (antes e após o período interventivo), com a finalidade de verificar o efeito do programa de intervenção motora, aplicou-se o Teste de Wilcoxon. Na descrição dos resultados, utilizou-se a mediana e a amplitude interquartílica (P25-P75). Os resultados evidenciaram mudanças significativas no desempenho motor nos três diferentes grupos (ID p=0,014, IC p=0,028 e GC p=0,005), e suportam a hipótese de que crianças com atrasos motores participantes do programa de intervenção apresentariam incremento no seu desempenho motor quando comparadas à avaliação inicial. As observações do comportamento das crianças desta amostra corroboram o pressuposto de que elas apresentariam, após a intervenção, incremento no seu desempenho social. A análise da variação dos escores totais de oportunidades de estimulação no lar, utilizando-se o Teste Qui-quadrado de McNemar, não evidenciou mudanças estatisticamente significativas nos diferentes grupos do estudo (p=1,000), rejeitando o pressuposto de que o programa de intervenção teria impacto positivo no contexto familiar, favorecendo mudanças significativas de engajamento nas diferentes atividades infantis rotineiras, bem como nas atitudes familiares frente às restrições destas crianças. Estratégias interventivas vinculadas ao contexto do desenvolvimento de crianças com atrasos motores promovem incremento em seu desempenho motor e social, e a identificação da criança de risco permite o acompanhamento precoce e a compreensão de suas necessidades. Estes achados sugerem a necessidade de programas de intervenção para famílias de baixa renda que otimizem as oportunidades de estimulação também no ambiente domiciliar. / The purpose of the present study, of quasi-experimental design, was to verify the effects of a motor intervention in three different contexts - individual at home (ID), individual at the daycare (IC) and in groups at the daycare (GC) - on motor and social development of children with motor delays, between 06 and 18 month-old, living in the suburbs of the city of Porto Alegre/RS, who were assisted by basic units of health affiliated to Moinhos de Vento Hospital and supported by communitarian daycare centers linked to the City Hall. Descriptions of the behavior of each child before and after the interventive period and characteristics of their home environment were associated to their motor performance. The sample for this research was voluntary, selected in a non probabilistic and intentional form. From a total of 96 assessed children, 40 presented percentile ranking below 25%, and, of those, 32 finished the 24 sessions of motor intervention, in a period of 12 weeks. Each interventive group was thus distributed: ID n=12, IC n=7 and GC n=13. The instruments used in this study were the behavior rating scale of Bayley Scales of Infant Development II (BSID-II), the Alberta Infant Motor Scale (AIMS) and the inventory Affordances in the Home Environment for Motor Development Self-Report (AHEMD-SR). The intervention program, carried out between May and November of 2007, was composed by playful activities which were planned to stretch and adjust the muscular tonus, to stimulate visual and auditory accompaniment, to control postures in different circumstances, to manipulate objects and to move around, in order to allow the children to experiment with new movement conditions and the overcoming of challenges. All the collected data were analyzed through the SPSS statistical program for Windows, version 13.0. In all the analyses, it was considered a significance level of p≤0,05. The result of the Shapiro-Wilk Normality Test, applied in the scores of motor performance in the first evaluation, suggested that the data was a non-normal distribution (p=0,04). Thus, non-parametric tests were used. In the comparison of the variables in the two evaluative periods (pre and post intervention), the Kruskal-Wallis’ Test was used and, when this test demonstrated significant differences between groups, the Mann-Whitney’s U Test was used. In the comparison of the percentile of motor performance of each group throughout time (before and after the interventive period), intending to verify the effect of the motor intervention program, the Wilcoxon Test was applied. In the description of the results, the median and the interquartilic range were used (P25-P75). The results showed significant improvement in the motor performance in the three different groups (ID p=0,014, IC p=0,028 and GC p=0,005), supporting the conviction that children with motor delays taking part in the intervention program would present increase in their motor performance when compared to the initial evaluation. The observations of children’s behavior from this sample corroborate with the conviction that they would show, after the intervention, increase in their social performance. The analysis of the variation of the total scores for opportunities of home stimulation, using McNemar Test, did not show evidence of significant statistical changes in the different study groups (p=1,000), rejecting the conviction that the intervention program would have a positive impact in the home environment, favoring significant changes of engagement in different infant routine activities, as well as in a shift in family attitude towards these children’s restrictions. Interventive strategies tied to the context of development of children with motor delays promote increase in their motor and social performance, and the identification of a risk child allows early accompaniment and the understanding of their necessities. These findings suggest the need of programs of intervention for low income families who also optimize the chances of stimulation in the home environment.
