O presente estudo busca identificar em que medida o pertencimento de classe social interfere nos sentidos e perspectivas do jovem brasileiro frente ao futebol espetáculo, bem como compreender os mecanismos sociais que determinam a decisão de os sujeitos investirem na carreira profissional esportiva em detrimento da trajetória escolar longa. Começamos com uma abordagem sociológica, a análise crítica dos processos de difusão, massificação e profissionalização do futebol ocorridas no contexto da sociedade pós-industrial. Enfocamos a conflituosa mutação da modalidade, inicialmente elitizada com fins social-distintivos para esporte de massa ideal de ascensão social da classe popular , além da dependência com a mídia, das razões que levaram a caracterizar-se como produto da indústria cultural, culminando com a transformação do futebol em mercadoria submetida às leis e lógica da sociedade de consumo. Em seguida, entrelaçamos as relações de poder, aliança e concorrência dos agentes sociais que participam do complexo campo das práticas esportivas com os canais com que o público jovem estabelece contato com o esporte espetáculo. Neste aspecto, especial atenção foi dada à mídia, difusora da ideologia de uma sociedade capitalista aberta, que reforça a idéia do esporte como via de ascensão social para indivíduos de baixa renda, na mesma medida em que oculta em seu discurso as reais probabilidades de concretização do sucesso esportivo. A pesquisa de campo foi realizada em duas escolas do município de São Bernardo do Campo (SP), uma da rede pública estadual e outra da rede particular de ensino. Assim, constituímos dois grupos com alunos de distintas classes sociais, compostos por estudantes do 1º ano do Ensino Médio, sexo masculino, com 15 anos de idade e praticantes de futebol nas aulas de Educação Física. Metodologicamente, fizemos uso da observação participante e de entrevistas como instrumentos para a coleta de dados. Conjugadas aos objetivos do estudo, estruturamos a análise do material colhido em seis categorias, articulando questões sobre o prosseguimento nos estudos e o trabalho, as tendências para a pratica esportiva profissional, as representações sociais em torno do futebol, os usos e costumes no tempo livre e as expectativas da pratica esportiva implicadas pela herança cultural familiar. Como referencial teórico de análise, utilizamos de Pierre Bourdieu os conceitos de campo, habitus, estratégia, capital econômico, social e, principalmente, capital cultural, partindo da hipótese de que o nível cultural dos alunos e seus familiares interferem nos sentidos e formas de apropriação do esporte. Entre outras conclusões, obtivemos como resultado a configuração de uma trajetória esportiva profissional voltada para os alunos de baixa classe social, em oposição à trajetória escolar longa, estrategicamente adotada pelos alunos de classe social alta.(AU)

This action research (AR) study explores an alternative approach to vocabulary instruction for low-proficiency university students: a change from targeting individual words from the general service list (West, 1953) to targeting frequent verb + noun collocations. A review of the literature indicated a focus on collocations instead of individual words could potentially address the students’ productive challenges with targeted vocabulary. Over the course of four reflective cycles, this thesis addresses three main aspects of collocation instruction. First, it examines if the students believe studying collocations is more useful than studying individual lexical items. Second, the thesis investigates whether a focus on collocations will lead to improvements in spoken fluency. This is tested through a comparison of a pre-intervention spoken assessment task with the findings from the same task completed 15 weeks later, after the intervention. Third, the thesis explores different procedures for the instructing of collocations under the classroom constraints of a university teaching context. In the first of the four reflective cycles, data is collected which indicates that the students believe a focus on collocations is superior to only teaching individual lexical items, that in the students’ opinion their productive abilities with the targeted structures has improved, and that delexicalized verb collocations are problematic for low-proficiency students. Reflective cycle two produces evidence indicating that productive tasks are superior to receptive tasks for fluency development. In reflective cycle three, productively challenging classroom tasks are investigated further and the findings indicate that tasks with higher productive demands result in greater improvements in spoken fluency. The fourth reflective cycle uses a different type of collocation list: frequent adjective + noun collocations. Despite this change, the findings remain consistent in that certain types of collocations are problematic for low-proficiency language learners and that the evidence shows productive tasks are necessary to improve the students’ spoken ability.

We present a stochastic agent-based model for the distribution of personal incomes in a developing economy. We start with the assumption that incomes are determined both by individual labour and by stochastic effects of trading and investment. The income from personal effort alone is distributed about a mean, while the income from trade, which may be positive or negative, is proportional to the trader's income. These assumptions lead to a Langevin model with multiplicative noise, from which we derive a Fokker-Planck (FP) equation for the income probability density function (IPDF) and its variation in time. We find that high earners have a power law income distribution while the low-income groups have a Levy IPDF. Comparing our analysis with the Indian survey data (obtained from the world bank website: http://go.worldbank.org/SWGZB45DN0) taken over many years we obtain a near-perfect data collapse onto our model's equilibrium IPDF. Using survey data to relate the IPDF to actual food consumption we define a poverty index (Sen A. K., Econometrica., 44 (1976) 219; Kakwani N. C., Econometrica, 48 (1980) 437), which is consistent with traditional indices, but independent of an arbitrarily chosen "poverty line" and therefore less susceptible to manipulation.

This study assessed the civic knowledge, skills, and attitudes of Hispanic eighth grade students in Miami-Dade County Public Schools (M-DCPS), Florida. Three hundred sixty one Hispanic students of Cuban (253), Colombian (57), and Nicaraguan (51) ancestry from 10 middle schools participated in the study. Two hundred twenty eight students were from low socio-economic status (SES) background, and 133 were of middle SES background. There were 136 boys and 225 girls. The International Association for the Evaluation of Educational Achievement Civic Education Student Questionnaire was used to collect data. The instrument assessed the students’ civic knowledge, skills, and attitudes. Multivariate analysis of variance was used to test for differences in the civic knowledge, skills, and attitudes of participants based on ancestry, SES, and gender. ^ The findings indicated that there was no significant difference in the civic knowledge, skills, and attitudes of Hispanic eighth grade students that were of Cuban, Colombian, and Nicaraguan ancestry. There was no significant difference in the civic skills and in five of the civic attitude scales for students from low SES families compared to those from middle SES families. However, there was a significant difference in the civic knowledge and in the civic attitude concerning classroom discussions and participation based on SES. The civic knowledge of middle SES students was higher than that of low SES students. Furthermore, middle SES Hispanic students displayed a higher mean score for the civic attitude of classroom discussions and participation than low SES students. There was no significant difference in the civic knowledge and in five of the civic attitude scales between boys and girls. However, there was a significant difference in the civic skills and the civic attitude of support for women’s rights between boys and girls. Hispanic girls displayed a higher mean score in civic skills than Hispanic boys. Furthermore, the mean score of civic attitude of support for women’s rights for Hispanic girls was higher than that of Hispanic boys. ^ It was concluded that Cuban, Colombian, or Nicaraguan participants did not demonstrate differences in civic attitudes and levels of civic knowledge and skills that eighth grade students possessed. In addition, when compared to boys, girls demonstrated a higher level of civic skills and a greater support for women’s rights and participation in politics and their roles in politics. Moreover, SES was demonstrated to be a key factor in the acquisition of civic knowledge, regardless of ancestry.^

Exploring the relationship between early oral reading fluency ability and reading comprehension achievement among an ethnically and racially diverse sample of young learners from low-income families, attending elementary school within a large public school district in southeast Florida is the purpose of this longitudinal study. Although many studies have been conducted to address the relationship between oral reading fluency ability and reading comprehension achievement, most of the existing research failed either to disaggregate the data by demographic subgroups or secure a large enough sample of students to adequately represent the diverse subgroups. The research questions that guided this study were: (a) To what extent does early oral reading fluency ability measured in first, second, or third grade correlate with reading comprehension achievement in third grade? (b) To what extent does the relationship of early oral reading fluency ability and reading comprehension achievement vary by demographic subgroup membership (i.e., gender, race/ethnicity, socioeconomic status) among a diverse sample of students? A predictive research design using archived secondary data was employed in this nonexperimental quantitative methods study of 1,663 third grade students who attended a cohort of 25 Reading First funded schools. The data analyzed derived from the Dynamic Indicators of Basic Early Literacy Skills Oral Reading Fluency (DIBELS ORF) measure administered in first, second, and third grades and the Florida Comprehensive Assessment Test of the Sunshine State Standards (FCAT-SSS) Reading administered in third grade. Linear regression analyses between each of the oral reading fluency and reading comprehension measures produced significant positive correlations. Hierarchical regression analyses supported the predictive potential of all three oral reading fluency ability measures toward reading comprehension achievement, with the first grade oral reading fluency ability measure explaining the most significant variance in third grade reading comprehension achievement. Male students produced significant overall differences in variance when compared to female students as did the Other student subgroup (i.e., Asian, Multiracial, and Native American) when compared to Black, White, and Hispanic students. No significant differences in variance were produced between students from low and moderate socioeconomic families. These findings are vital toward adding to the literature of diverse young learners.

Objective: Evaluate the determinants of morbidity and mortality in an obstetric intensive care unit and professional medical skills of students/residents at a university hospital. Methods: observational cross - sectional with 492 pregnant/pue rperal women and 261 students/residents. Patients were admitted to the obstetric intensive care unit during a year, being informed about the proposals of the study and a questionnaire was applied. The analysis was performed using Microsoft Excel 2013 and G raphPad6. Chi - square tests were used to evaluate risk factors and student t test evaluates resident/students' skills concerning the cognitive test and the Mini - Cex. Results: the main risk factors to near miss were: non - white race (OR = 2.527; RR = 2.342) ; marital status(married women) (OR = 7.968; RR = 7.113) , schooling (primary) (OR = 3.177 ; RR = 2.829) , from country town (OR = 4.643 ; RR = 4.087), low income (OR = 7014 ; RR = 5.554) , gestational hypertensive disorders (OR = 16.35 ; RR = 13.27) , re alization of pre - natal (OR = 5.023 ; RR = 4.254) and C - section before labor(OR = 39.21 ; RR = 31.25). In cognitive/Mini - cex analysis were noted significant difference in the performance of students on the subject (3.75 ± 0.93, 4.03 ± 0.94 and 4.88 ± 0.35). We still observed the best performance of residents, when compared to graduation students (p < 0.01). Conclusions: the prevalence of near miss was associated with socioeconomic/clinics factors and care issues, revealing the importance of interventions to improve these indicators. In addition, we suggest a better curriculum insertion of this subject in the medical Course disciplines due the importance to avoid the near miss through of adequacy of medical education.

The American approach to disparities in educational achievement is deficit focused and based on false assumptions of equal educational opportunity and social mobility. The labels attached to children served by compensatory early childhood education programs have evolved, e.g., from “culturally deprived” into “at-risk” for school failure, yet remain rooted in deficit discourses and ideology. Drawing on multiple bodies of literature, this thesis analyzes the rhetoric of compensatory education as viewed through the conceptual lens of the deficit thinking paradigm, in which school failure is attributed to perceived genetic, cultural, or environmental deficiencies, rather than institutional and societal inequalities. With a focus on the evolution of deficit thinking, the thesis begins with late 19th century U.S. early childhood education as it set the stage for more than a century of compensatory education responses to the needs of children, inadequacies of immigrant and minority families, and threats to national security. Key educational research and publications on genetic-, cultural-, and environmental-deficits are aligned with trends in achievement gaps and compensatory education initiatives, beginning mid-20th century following the Brown vs Board declaration of 1954 and continuing to the present. This analysis then highlights patterns in the oppression, segregation, and disenfranchisement experienced by low-income and minority students, largely ignored within the mainstream compensatory education discourse. This thesis concludes with a heterodox analysis of how the deficit thinking paradigm is dependent on assumptions of equal educational opportunity and social mobility, which helps perpetuate the cycle of school failure amid larger social injustices.

Empirical studies of education programs and systems, by nature, rely upon use of student outcomes that are measurable. Often, these come in the form of test scores. However, in light of growing evidence about the long-run importance of other student skills and behaviors, the time has come for a broader approach to evaluating education. This dissertation undertakes experimental, quasi-experimental, and descriptive analyses to examine social, behavioral, and health-related mechanisms of the educational process. My overarching research question is simply, which inside- and outside-the-classroom features of schools and educational interventions are most beneficial to students in the long term? Furthermore, how can we apply this evidence toward informing policy that could effectively reduce stark social, educational, and economic inequalities?
The first study of three assesses mechanisms by which the Fast Track project, a randomized intervention in the early 1990s for high-risk children in four communities (Durham, NC; Nashville, TN; rural PA; and Seattle, WA), reduced delinquency, arrests, and health and mental health service utilization in adolescence through young adulthood (ages 12-20). A decomposition of treatment effects indicates that about a third of Fast Track’s impact on later crime outcomes can be accounted for by improvements in social and self-regulation skills during childhood (ages 6-11), such as prosocial behavior, emotion regulation and problem solving. These skills proved less valuable for the prevention of mental and physical health problems.
The second study contributes new evidence on how non-instructional investments – such as increased spending on school social workers, guidance counselors, and health services – affect multiple aspects of student performance and well-being. Merging several administrative data sources spanning the 1996-2013 school years in North Carolina, I use an instrumental variables approach to estimate the extent to which local expenditure shifts affect students’ academic and behavioral outcomes. My findings indicate that exogenous increases in spending on non-instructional services not only reduce student absenteeism and disciplinary problems (important predictors of long-term outcomes) but also significantly raise student achievement, in similar magnitude to corresponding increases in instructional spending. Furthermore, subgroup analyses suggest that investments in student support personnel such as social workers, health services, and guidance counselors, in schools with concentrated low-income student populations could go a long way toward closing socioeconomic achievement gaps.
The third study examines individual pathways that lead to high school graduation or dropout. It employs a variety of machine learning techniques, including decision trees, random forests with bagging and boosting, and support vector machines, to predict student dropout using longitudinal administrative data from North Carolina. I consider a large set of predictor measures from grades three through eight including academic achievement, behavioral indicators, and background characteristics. My findings indicate that the most important predictors include eighth grade absences, math scores, and age-for-grade as well as early reading scores. Support vector classification (with a high cost parameter and low gamma parameter) predicts high school dropout with the highest overall validity in the testing dataset at 90.1 percent followed by decision trees with boosting and interaction terms at 89.5 percent.

There are a great number of evidences showing that education is extremely important in many economic and social dimensions. In Brazil, education is a right guaranteed by the Federal Constitution; however, in the Brazilian legislation the right to the three stages of basic education: Kindergarten, Elementary and High School is better promoted and supported than the right to education at College level. According to educational census data (INEP, 2009), 78% of all enrolments in College education are in private schools, while the reverse is found in High School: 84% of all matriculations are in public schools, which shows a contradiction in the admission into the universities. The Brazilian scenario presents that public universities receive mostly students who performed better and were prepared in elementary and high school education in private schools, while private universities attend students who received their basic education in public schools, which are characterized as low quality. These facts have led researchers to raise the possible determinants of student performance on standardized tests, such as the Brazilian Vestibular exam, to guide the development of policies aimed at equal access to College education. Seeking inspiration in North American models of affirmative action policies, some Brazilian public universities have suggested rate policies to enable and facilitate the entry of "minorities" (blacks, pardos1, natives, people of low income and public school students) to free College education. At the Federal University of the state Rio Grande do Norte (UFRN), the first incentives for candidates from public schools emerged in 2006, being improved and widespread during the last 7 years. This study aimed to analyse and discuss the Argument of Inclution (AI) - the affirmative action policy that provides additional scoring for students from public schools. From an extensive database, the Ordinary Least Squares (OLS) technique was used as well as a Quantile Regression considering as control the variables of personal, socioeconomic and educational characteristics of the candidates from the Brazilian Vestibular exam 2010 of the Federal University of the state Rio Grande do Norte (UFRN). The results demonstrate the importance of this incentive system, besides the magnitude of other variables

Résumé : PROBLÉMATIQUE: L’exposition résidentielle à l’humidité excessive ou aux moisissures est maintenant reconnue comme un facteur important influençant la santé respiratoire. Cette problématique a été peu étudiée chez les étudiants universitaires, bien que vulnérables par leur faible revenu et leur statut de locataire. OBJECTIFS: Cette maîtrise vise à décrire la prévalence (a) de l’exposition résidentielle à l’humidité excessive ou aux moisissures et (b) des maladies respiratoires chez les étudiants universitaires, ainsi qu’à (c) examiner l’association entre l’exposition résidentielle à l’humidité excessive ou aux moisissures et ces maladies. MÉTHODES: En 2014, une enquête électronique a été réalisée auprès de 2097 étudiants enregistrés à l’Université de Sherbrooke (Québec, Canada). Lorsque possible, des questions et des scores validés ont été utilisés pour estimer les prévalences des maladies respiratoires (rhinite allergique, asthme et infections respiratoires), de l’exposition résidentielle à l’humidité excessive ou aux moisissures et des covariables (ex. : revenu annuel familial, statut tabagique, atopie familiale, caractéristiques de l’étudiant). Les associations entre cette exposition et ces maladies ont d’abord été examinées par des tests de chi-carré en utilisant un seuil alpha de 0,05. Des régressions logistiques multivariées ont ensuite été utilisées pour déterminer les associations brutes et ajustée entre cette exposition et les maladies respiratoires. Les analyses descriptives ont été pondérées pour le sexe, l’âge et le campus d’étude. RÉSULTATS: L’exposition à l’humidité excessive ou aux moisissures était fréquente parmi les participants (36,0%; Intervalle de confiance (IC)95% : 33,9-38,1). Ceux-ci ont également été nombreux à rapporter une rhinite allergique (23,9%; IC95% :22,0-25,8), de l’asthme (32,6%; IC95% : 30,5-34,7) et des infections respiratoires (19,4%; IC95% :17,7-21,2) au cours de la dernière année. Après ajustement, les associations demeuraient significatives entre l’exposition à l’humidité excessive ou aux moisissures et la rhinite allergique (Rapport de cote (RC) : 1,30; IC95% : 1.05-1.60), l’asthme RC : 1,75; IC95% : 1,42-2,16), mais pas les infections respiratoires (RC : 1,07; IC95% : 0,85-1.35). CONCLUSIONS: La prévalence élevée de l’exposition résidentielle des étudiants universitaires à l’humidité excessive ou aux moisissures, de même que son association avec l’asthme et la rhinite allergique, mettent en lumière sa contribution potentielle à la forte prévalence des maladies respiratoires ayant une composante allergique dans cette population. Cette étude fournit un nouveau levier pour les organisations de santé publique et leurs partenaires afin d’adapter les stratégies préventives ciblant les logements insalubres, particulièrement chez les populations vulnérables.

[EN] 3D microfluidic device fabrication methods are normally quite expensive and tedious. In this paper, we present an easy and cheap alternative wherein thin cyclic olefin polymer (COP) sheets and pressure sensitive adhesive(PSA) were used to fabricate hybrid 3D microfluidic structures, by the Origami technique, which enables the fabrication of microfluidic devices without the need of any alignment tool. The COP and PSA layers were both cut simultaneously using a portable, low-cost plotter allowing for rapid prototyping of a large variety of designs in a single production step. The devices were then manually assembled using the Origami technique by simply combining COP and PSA layers and mild pressure. This fast fabrication method was applied, as proof of concept, to the generation of a micromixer with a 3D-stepped serpentine design made of ten layers in less than 8 min. Moreover, the micromixer was characterized as a function of its pressure failure, achieving pressures of up to 1000 mbar. This fabrication method is readily accessible across a large range of potential end users, such as educational agencies (schools,universities), low-income/developing world research and industry or any laboratory without access to clean room facilities, enabling the fabrication of robust, reproducible microfluidic devices.

Background: Under nutrition is a problem of severe magnitude in low income countries like Nigeria. Adolescent school children might also be vulnerable. The dearth of data hinders planning of school health and nutrition programmes for school children. Objective: To determine the prevalence of stunting, thinness; vitamin A and iron deficiencies among adolescent students in Nsukka urban, Nigeria and to determine factors that are associated with these nutritional problems. Methods: A total of 400 participants were randomly selected from 717 students aged 12 – 18 years in 3 randomly selected secondary schools. Questionnaires, anthropometric measurements, and blood analyses were the data collection methods employed. Results: The prevalence of stunting was 33.3% and thinness 31.0%. Neither overweight nor obesity was observed. While 64.0% were anaemic; 44.0% had vitamin A deficiency (VAD). A total of 48.0% had both anaemia and stunting, 42% had VAD + thinness; while 40% had anaemia + VAD. Household income was a predictor of vitamin A status. Children from medium/ high income households had higher odds of having VAD than those from low income households (AOR=0.14; 95% CI=0.031, 0.607; P=0.009). Household income (AOR=0.12; 95% CI=0.021, 0.671; P=0.016), and age (AOR=0.09; 95% CI=0.014, 0.587; P=0.012) were independent determinants of height-for-age status. Conclusion: Among urban adolescent students in Nigeria, stunting, thinness, anaemia and VAD were problems of public health significance. Age and household monthly income played major roles.
