Published: October 2020

Propomos elencar alguns aspectos relevantes na composição dos “terreiros traçados” de Campina Grande-PB, entendendo o que tornou possível o constructo de espaços de duplo pertencimento religioso: à jurema sagrada e ao candomblé, simultaneamente. As discussões teóricas, bem como as experiências de observação participante e entrevistas concedidas pelas lideranças mais antigas da cidade permitiram pormenorizar a crítica e apontar os limites de categorias recorrentes nos estudos de religiões afro-brasileiras e ameríndias, a saber, sincretismo e hibridismo. Compreendemos que para analisar a formação identitária desses espaços religiosos se faz necessário observar as dinâmicas sociais e entrecruzamentos culturais que lhes são subjacentes.

Authors: Paredes-Labra Joaquín
Published: October 2020

Este estudio analiza las dificultades para impulsar transformaciones en la docencia universitaria, en concreto de la formación de docentes. Los objetivos son clarificar concepciones propias sobre el currículo, así como las dificultades surgidas, al tiempo que se genera un aprendizaje compartido con otros innovadores que reflexionan conjuntamente. El referencial teórico del trabajo hunde sus raíces tanto en una idea de pedagogía abierta que propicia la puesta en marcha del Espacio europeo de educación superior como en la pedagogía post-formal de Kincheloe. La metodología es de tipo evaluativo y biográfico-narrativo, basada en evidencias recogidas a lo largo de una trayectoria profesional como docente.  Entre los principales resultados cabe plantear cómo el docente que investiga sobre su propia práctica toma conciencia de las fortalezas y dificultades para practicar innovaciones con pedagogías abiertas y post-formales.

Modeling and investigation in the proposal of a codisciplinary REI of mathematics and history
Authors: Sala Sebastià Gemma , Barquero Farràs Berta , Font Moll Vicenç
Published: October 2020

ResumenEste trabajo empieza con la discusión de las nociones de indagación y de modelización y en qué sentido estos constructos son cuestionados e integrados en el paradigma de cuestionamiento del mundo y, en particular, a través de la propuesta de los recorridos de estudio e investigación (REI). Discutiremos los modelos epistemológicos y pedagógicos subyacentes que las propuestas de modelización e indagación ofrecen, y cómo estos pueden ser reformulados en el ámbito de investigación de la teoría antropológica de lo didáctico. Nos centraremos entonces en analizar el caso de un REI codisciplinar de matemáticas e historia, que ha sido experimentado a nivel de Secundaria, para mostrar cómo indagación y modelización aparecen como dos actividades indisociables en la construcción del conocimiento codisciplinar matemático-histórico.Palabras-Clave: Modelización Matemática; Indagación; CodisciplinarAbstractThis paper starts with the discussion of the notions of inquiry and modelling and how these constructs are questioned and integrated into the paradigm of questioning the world, in particular, through the proposal of the study and research paths (SRP). We focus on underlying the epistemological and pedagogical models that inquiry-based and modelling approaches offer and how they can be understood in the framework of the anthropological theory of didactics. Then, we present the case of a codisciplinary SRP that links mathematics and history, which has been implemented at Secondary school level, to show how inquiry and modelling appear as two inseparable processes in the construction of mathematical-historical codisciplinary knowledge.Keywords: Mathematical Modeling, Inquiry, Codisciplinary.

Authors: Ferraz Maria Sarah Tristão , Guimarães Michelle Ferreira , Nunes Janaina De Alencar , Azevedo Elma Heitmann Mares
Published: October 2020

Introdução: Envelhecer envolve mudanças que podem comprometer órgãos e funções. Com o crescimento da população idosa há grande demanda de idosos saudáveis suscetíveis a alterações na deglutição. Objetivo: Identificar o risco de disfagia e avaliar a qualidade de vida em deglutição de idosos saudáveis. Método: Estudo descritivo, observacional e transversal, aprovado pelo Comitê de Ética, no 1.797.382. Foram incluídos indivíduos com idade igual ou superior a 60 anos, de ambos os sexos e considerados saudáveis. A pesquisa foi realizada nas dependências da instituição e foram aplicados os protocolos EAT-10 e SWAL-QOL. Resultados: Participaram 110 idosos saudáveis com média de idade de 71 anos. Foram identificados 41 (37,27%) indivíduos com risco de disfagia, sendo a maioria do sexo masculino (n = 26; 63,41%) e com idade igual ou superior a 70 anos (n = 25; 60,98%). Não houve relação estatística entre risco de disfagia, sexo e faixa etária. Quanto ao SWAL-QOL houve diferença estatística entre os sexos para os domínos “deglutição como um fardo”, “frequência de sintomas” e “saúde mental”, porém sem diferença nas faixas etárias. Independente do sexo e idade, não houve impacto na qualidade de vida relacionada à deglutição. Não houve associação entre risco de disfagia e qualidade de vida. Conclusão: Idosos saudáveis apresentam risco de disfagia mais frequente após 70 anos e menores escores para os domínios “sono” e “fadiga” no SWAL-QOL.

Published: October 2020

O objetivo deste artigo foi demonstrar o impacto do programa de incentivos fiscais no desenvolvimento das organizações, enfatizando indicadores de empregabilidade e produtividade. Mediante metodologia pesquisa descritiva e qualitativa, foram utilizados dados bibliográficos coletados de publicações como Anuário da Indústria Automobilística Brasileira dos anos de 2010 a 2018, com todas as informações do setor, onde se busca dar ênfase nos indicadores eleitos para este processo de análise. O resultado esperado procurou verificar se há impacto positivo ou negativo nos indicadores analisados baseados nos incentivos, uma vez que o investimento governamental precisa ser mensurado dentro dos retornos previstos no programa e na sua publicação como força de Lei. O setor automobilístico com toda a sua pujança, recebe frequentes incentivos, contudo, nem todos têm resultados satisfatórios e alcançam suas metas e objetivos. Este novo programa, busca de uma forma mais abrangente, alimentar toda a cadeia de valores do setor automobilístico, define metas obrigatórias de eficiência energética, segurança veicular, investimentos em pesquisa e desenvolvimento, recuperação da base de fornecedores, desenvolvimento tecnológico, relações trabalhistas, de eficiência energética, inspeção veicular, logística e sistema tributário. Como contribuição, este artigo procurou demonstrar se as renúncias fiscais promovidas pelo Estado atingem seus objetivos, promovem contribuições no número de empregos e, também no aumento do processo produtivo. Como conclusão final, foi possível perceber após a análise dos dados, que as variações dos indicadores de empregabilidade e produtividade estavam de acordo com os incentivos fiscais oferecidos, mesmo considerando-se as sazonalidades

This investigation was undertaken to explore and compare the effect of bipolar I disorder (BD) and major depressive disorder (MDD) on workforce function. The data for this analysis were procured from the Canadian Community Health Survey (CCHS 1.2). The sample consisted of 20 747 individuals (≥ 18 years old and currently working); the proportions screening positive for lifetime BD and MDD were 2.4% and 11.2%, respectively. Individuals with BD or MDD had a signifi cantly lower mean annual income, compared to people without these disorders. Individuals with BD had a signifi cantly lower annual income when compared to MDD (p $lt; 0.05). Results from a multiple logistic regression also indicate that employed individuals with BD had greater odds of reporting one or more mental health disability days in the past two weeks, compared with those with MDD (OR = 1.6; 95% CI = 1.0 to 2.6). Currently employed individuals with BD had lower odds of “good job security” relative to those with MDD (OR = 0.6 95% CI = 0.5 to 0.9). The data herein underscore the pernicious effect of BD on workforce function, and suggest that opportunistic screening for BD in all individuals utilizing employment assistance programs for depression might be warranted.
Risk factors for falling among community-dwelling seniors using home-care services: An extended hazards model with time-dependent covariates and multiple events
Authors: Leclerc B.S. , Bégin C. , Cadieux E. , Goulet L. , Leduc N. , Kergoat M.J. , Lebel P.
Published: October 2020

The identification of risk factors for falls in longitudinal studies becomes difficult because of exposures that change during the follow-up and also because individual subjects may experience an event more than once. These issues have been neglected and improper statistical techniques have been used. The typical approaches have been to report the proportion of fallers or the time to first fall. Both avoid the underlying assumption of independence between events and discard pertinent data. We review the existing methods and propose a Cox hazards extension. We exemplify it in the study of potential risk factors associated with all falls in 959 seniors. Finally, we compare the results of the proposed Wei, Lin, & Weissfeld (WLW) method with those of several other techniques. Stable exposure variables measured at baseline and updated time-varying exposures include socio-demographic characteristics, BMI, nutritional risk, alcohol consumption, home hazards, gait and balance, and medications. Results demonstrate that the usual methods of analyzing risk factors for falling are inappropriate, as they produce considerable biases relative to the WLW model using time-dependent covariates. Results also show that modeling for first events may be inefficient, given that the risk of occurrence varies between falls.

The purpose of this study was to describe the influence of literacy, consisting of prose and numeracy skill, math anxiety, attained education and context of information on participant ability to comprehend Internet-based colorectal cancer prevention information. Prose, numeracy, and math-anxiety data, as well as demographic details, were collected for 140 Canadian adults, aged 50+ years. Participants had adequate prose literacy (STOFHLA) scores, high STOFHLA numeracy scores, moderate levels of health-context numeracy, poorer generalcontext numeracy and moderate math anxiety. There was better comprehension by participants of common (9.14/11) compared with uncommon (7.64/11) colorectal cancer information (p $lt; 0.01). Prose literacy, numeracy, math anxiety and attained education accounted for 60% of the variation in participant comprehension scores. Numeracy, ranging from basic to advanced proficiency, is required to understand online cancer risk information. Prose literacy enhances numeracy when the subject matter is less familiar. These findings highlight the importance of presenting Web-based information that accommodates diverse health literacy and numeracy levels.
Deprivation and unintentional injury hospitalization in Quebec children
Authors: Gagné Mathieu , Hamel Denis
Published: October 2020

Injuries disproportionately affect children from deprived areas. This study examines the links between the material and social dimensions of deprivation and injury hospitalizations in children aged 14 years or under from 2000 to 2004. Hospitalization data are from the Quebec hospital administrative data system, whereas socio-economic characteristics of individuals were estimated based on the smallest geographic areas for which Canadian census data were disseminated. The Poisson regression model was used to calculate the relative risks of hospitalization for seven categories of unintentional injury. A total of 24 540 injury hospitalizations were examined. Hospitalization in children is associated with both dimensions of deprivation. Injuries to pedestrians and motor vehicle occupants and injuries related to burns and poisonings are clearly associated with both dimensions of deprivation. These inequalities should be considered in the development of preventive measures.
Injury data in British Columbia: policy maker perspectives on knowledge transfer
Authors: Mitton C. , MacNab Y.C. , Smith N. , Foster L.
Published: October 2020

Provincial and regional decision makers in the injury prevention field were interviewed in British Columbia (B.C.) to obtain their views about best processes for the transfer or dissemination of relevant data. These decision makers (n = 13) indicated that data should provide them with a holistic and comprehensive picture to support their decision processes. In addition, they felt information about injury types and rates should be linked backward to determinants or causes and forward to consequences or outcomes. This complete chain of data is needed for planning and evaluating health promotion interventions. It was also felt that data providers needed to devote more effort to fostering effective receptor capacity, so that injury prevention professionals will be better able to understand, interpret and apply the data. These findings can likely be generalized to other jurisdictions and policy areas, and offer additional insight into the practicalities of knowledge transfer and exchange in researcher/decision maker partnerships.
School-based tobacco-control programming and student smoking behaviour
Authors: Murnaghan DA , Leatherdale ST , Sihvonen M , Kekki P
Published: October 2020

The study examined the association of a school-based tobacco-control program with students’ smoking behaviour over time using three cross-sectional, provincial census datasets (grade 10 students in 1999, grade 11 students in 2000, grade 12 students in 2001). Data were collected from all secondary schools in Prince Edward Island (Canada) using the Tobacco module of the School Health Action, Planning and Evaluation System (SHAPES). The proportion of regular smokers increased from grade 10 (22.3%) to grade 12 (27.8%, χ2 = 10.35, df = 1, p $lt; 0.001). Being exposed to different school-based tobacco programs and policies in grades 10 and 11 was not associated with the smoking behaviour of grade 12 students. The strongest predictors of smoking behaviour were having friends or close family members who smoke. This preliminary evidence suggests that programs and policies associated with banning smoking and enforcing smoking restrictions at school may be insufficient unless they also address the influence of smoking peers and family members and link to comprehensive programming within the broader context of other community and policy level interventions.
A deprivation index for health planning in Canada
Authors: Pampalon R , Hamel D , Gamache P , Raymond G
Published: October 2020

Administrative databases in the Canadian health sector do not contain socio-economic information. To facilitate the monitoring of social inequalities for health planning, this study proposes a material and social deprivation index for Canada. After explaining the concept of deprivation, we describe the methodological aspects of the index and apply it to the example of premature mortality (i.e. death before the age of 75). We illustrate variations in deprivation and the links between deprivation and mortality nationwide and in different geographic areas including the census metropolitan areas (CMAs) of Toronto, Montréal and Vancouver; other CMAs; average-size cities, referred to as census agglomerations (CAs); small towns and rural communities; and five regions of Canada, namely Atlantic, Quebec, Ontario, the Prairies and British Columbia. Material and social deprivation and their links to mortality vary considerably by geographic area. We comment on the results as well as the limitations of the index and its advantages for health planning.
Utilisation des données administratives pour comprendre la distribution géographique de la détermination des cas
Authors: Yiannakoulias N. , Schopflocher D.P. , Svenson L.W.
Published: October 2020

Nous avons examiné la variabilité géographique de l’information générée à partir de différentes définitions de cas d’asthme infantile, provenant des données administratives sur la santé utilisées en Alberta, au Canada. Notre objectif était de déterminer si les analyses fondées sur différents algorithmes de détermination des cas permettent ou non de définir les groupes géographiques dans la même région que celle sur laquelle porte l’étude. Notre groupe d’étude reposait sur une cohorte fermée d’enfants asthmatiques nés en 1988. Nous avons utilisé une statistique sur l’analyse spatiale pour établir les variations de l’emplacement approximatif des groupes géographiques liés à l’asthme selon différentes définitions de cas. Nos résultats indiquent que l’algorithme de détermination des cas et la source de données n’ont pas une très grande incidence sur les profils géographiques. Par exemple, les asthmatiques identifiés à partir des données sur les réclamations au titre de frais médicaux ont démontré un regroupement semblable à celui des asthmatiques définis à partir des données sur l’hospitalisation et provenant du service d’urgence. Cependant, il faut bien prendre en considération les estimations de la prévalence et de l’incidence et les valider par rapport aux autres sources de données.
Association of obesity with mood and anxiety disorders in the adult general population
Authors: Gadalla T.M.
Published: October 2020

Obesity is a major health concern. It has been implicated as a risk factor for several physical illnesses, functional limitations and poor quality of life. However, while the physical consequences of obesity are well established, the relationship between obesity and mental health is still unclear. This study used data collected in the Canadian Community Health Survey, cycle 3.1 (2005) to examine this relationship in adults 20 to 64 years old. Obesity was significantly associated with mood disorders, but not with anxiety disorders. When adjusting for sex, place of birth, smoking, and functional limitations, all of which were significantly associated with obesity, the odds of obesity remained significantly higher in persons with mood disorders (with or without anxiety disorders). It is still unclear whether the relationship between obesity and depression is causal, and if so, whether obesity causes depression or depression causes obesity. Implications for health care providers and suggestions for future research are discussed.
The comorbidity burden of the treated asthma patient population in British Columbia
Authors: Prosser R. , Carleton B. , Smith A.
Published: October 2020

To date there has been little investigation of the prevalence of comorbid conditions in asthma patients. Using 1996/97 cross-sectional health services administrative data for British Columbia, we compared the prevalence of comorbid conditions in treated adult asthma patients with the general adult population using a standardized comorbidity identification methodology, the Adjusted Clinical Group (ACG) Case-Mix System. We also profiled the comorbidity burden of pediatric asthma patients. Adults with asthma were significantly more likely to have a range of comorbidities, including respiratory infections, allergic rhinitis and 8 high impact/high prevalence chronic conditions (HIHPCCs). One in 4 adults with asthma had depression, the most prevalent HIHPCC. Children with asthma had a lower comorbidity burden than adults, but 12.6% had a stable or unstable chronic medical condition, with the most prevalent HIHPCC also depression. Adults with asthma had a high and complex comorbidity burden, particularly in terms of multiple chronic conditions. We discuss the implications for services planning and delivery.
Effets de la socialisation à la maison sur la prédisposition des jeunes au tabagisme : analyse secondaire de l’Enquête sur le tabagisme chez les jeunes au Canada 2004-2005
Authors: Schultz A.S.H. , Nowatzki J. , Dunn D.A. , Griffith E.J.
Published: October 2020

Objectif

Déterminer les relations entre la prédisposition des plus jeunes au tabagisme et quatre variables relatives aux ménages associées à la socialisation au tabagisme : tabagisme chez les parents ainsi que chez les frères et sœurs, restrictions quant au tabagisme à la maison, et exposition au tabagisme à bord de véhicules.

Méthodes

On a effectué une analyse secondaire de l’Enquête sur le tabagisme chez lesjeunes au Canada 2004-2005 au moyen d’une régression logistique afin d’étudier les rapports entre la prédisposition des jeunes au tabagisme, le sexe, et quatre variables relatives aux ménages associées à la socialisation au tabagisme. La prédisposition au tabagisme a été définie par trois niveaux d’expérience et d’intention quant au tabagisme : non-fumeur non prédisposé, non-fumeur prédisposé et expérimentateur/fumeur. L’enquête nationale a été menée auprès de 29 243 élèves de la 5e à la 9e année provenant d’écoles publiques et privées échantillonnées de façon aléatoire dans dix provinces.

Résultats

Chez les non-fumeurs, la probabilité d’être prédisposé au tabagisme augmente avec le fait d’avoir un frère ou une sœur qui fume, l’absence d’une interdiction complète quant au tabagisme à la maison, et le fait d’avoir voyagé à bord d’un véhicule en compagnie d’un fumeur au cours de la semaine précédente, toutes les autres variables du modèle ayant été ajustées. Ces variables font aussi augmenter la probabilité d’être un expérimentateur/fumeur plutôt qu’un non-fumeur prédisposé. La catégorie de tabagisme des parents ne s’est pas révélée significative dans ces modèles.

Conclusion

Les messages de dénormalisation, transmis par la mise en application d’interdictions de fumer à la maison et à bord de véhicules, semblent aider les jeunes à rester déterminés à ne pas fumer et ce, quelle que soit la catégorie de tabagisme des parents.
