Heterophoria, fusional amplitudes and stereoacuity in school aged children

The stability of binocular vision depends on good fusional amplitudes and its measurements provide information about the patient’s ability to cope with a deviation. However, weak correlations between fusional amplitudes and angle of deviation have been reported in the literature. There are no uniform normative values of fusional amplitudes, even though standards for vergence have been established since 1940s. Aims: 1) Determine the prevalence of heterephoria; 2) Determine the relationship between heterophoria, fusional amplitudes and stereoacuity in children.

Senses of body image in adolescents in elementary school

OBJECTIVE To comprehend the perception of body image in adolescence. METHODS A qualitative study was conducted with eight focus groups with 96 students of both sexes attending four public elementary school institutions in the city of Rio de Janeiro, Southeastern Brazil, in 2013. An interview guide with questions about the adolescents’ feelings in relation to: their bodies, standards of idealized beauty, practice of physical exercise and sociocultural influences on self-image. In the data analysis we sought to understand and interpret the meanings and contradictions of narratives, understanding the subjects’ context and reasons and the internal logic of the group. RESULTS Three thematic categories were identified. The influence of media on body image showed the difficulty of achieving the perfect body and is viewed with suspicion in face of standards of beauty broadcast; the importance of a healthy body was observed as standards of beauty and good looks were closely linked to good physical condition and result from having a healthy body; the relationship between the standard of beauty and prejudice, as people who are not considered attractive, having small physical imperfections, are discriminated against and can be rejected or even excluded from society. CONCLUSIONS The standard of perfect body propagated by media influences adolescents’ self-image and, consequently, self-esteem and is considered an unattainable goal, corresponding to a standard of beauty described as artificial and unreal. However, it causes great suffering and discrimination against those who do not feel they are attractive, which can lead to health problems resulting from low self-esteem.

Pre-harvest cane burning and health: the association between school absences and burning sugarcane fields

The objective of this study was to investigate an association between pre-harvest sugarcane burning and respiratory diseases in children under five years of age. The following data were collected in five schools in the city of Araraquara, SP, Southeastern Brazil, between March and June 2009: daily records of absences and the reasons stated for these absences, total concentration of suspended particulate matter (µg/m3), and air humidity. The relationship between the percentage of school absences due to respiratory problems and the concentration of particulate matter in March and from April to June presented a distinct behavior: absences increased alongside the increase in particulate matter concentration. The use of school absences as indicators of this relationship is an innovative approach.

Education for health: alcohol and young aged school teenagers

Introduction: Alcohol consumption starts at an early age in Portuguese people. Health problems and risk behavior associated with excessive consumption can be prevented or highly reduced through effective school programs. Health professionals, such as biomedical scientists, (BSc), are important in promoting healthy lifestyles through the transmission of knowledge. Objective: Explore the role of the BSc in promoting health via intervention and clarification actions, (ICA), with 9th grade students from Agrupamento de Escolas da Portela e Moscavide (AEPM) and Visconde Juromenha (AEVJ); Verify the relationship between participating in the ICA and the level of knowledge acquired from it. Methods: Behaviors and beliefs concerning alcohol consumption and knowledge about the repercussions of it in the human body, mainly regarding the liver, were assessed by questionnaire. The questionnaire was completed before and after the ICA, by the control group (CG) and the study group (SG), respectively. The answers concerning knowledge were given points, later converted to a score from 0 to 100%. Data was analyzed applying descriptive statistics and the t-student test using SPSS 20.0. Results: After statistical analysis, it was found an average score of 48.8% for SG and 46.2% for CG. The difference between groups was statistically significant only in AEPM where ICA included a practical methodology (microscopic and macroscopic observation of pork livers), contrary to AEVJ. Conclusions: BSc intervention through ICA’s improves teenagers’ knowledge. Theoretical knowledge associated with practical approaches improves the retention of information and the development of a conscious behavior about the consumption of alcohol.

The impact of firm-promoted accreditation of prior learning processes on the worker-organization relationship

The process of Competences Recognition, Validation and Certification , also known as Accreditation of Prior Learning (APL), is an innovative means of attaining school certificates for individuals without an academic background. The main objective of this process is to validate what people have learned in informal contexts, in order to attribute academic certificates. With the increasing interest of the qualification of workers and governmental support, more and more Portuguese organizations promote this process within their facilities and their work hours. This study explores the relationship between the promotion of this Human Resource Development Programme and employee’s attitudes (Job Satisfaction and Organizational Commitment) and behaviours (Extra-role Organizational Citizenship Behaviours) towards the organization they work for. Results of a cross-sectional survey of Portuguese Industrial Workers (N=135) showed that statistical significant results are in the higher levels of Voice Behaviours (a dimension of Extra-role Organizational Citizenship Behaviour in the groups of workers who were involved or had graduated from the firm promoted APL process.

School governance and academic excellence: the representations of distinguished students in an annual award of excellence

Within a research project on «academic excellence in the state school», this paper is a contribution to the sociological reflection on the cultural and organisational characteristics of the school and its relationship with the academic success of students. The data we present stem from a case study underway at a secondary school in the north of Portugal, referring to the universe of students that since 2003 have distinguished themselves for achieving grades equal to or greater than 18 (on a scale of 0 to 20) and have thus been included in the school’s Framework of Excellence. From a contextual approach to this educational practice, we focused on the cultural characteristics of the school/subject as analytical support for the study of school and non-school dimensions in their mutual connections. To this end, we used the information from document analysis and data collected from a questionnaire survey administered to more than two-thirds of the students included in the above-mentioned Framework of Excellence. Subsequently, we will use the data from this survey to understand the extent to which academic excellence is perceived as an indivisible social construction of the school’s political and organisational matrix, particularly in terms of the educational and teaching guidelines adopted by the management body. We will conclude by questioning the meaning of the school’s management policies regarding the emphasis on educational outcomes, with particular focus on the representations of excellent students in the processes of school leadership, teaching organisation, school merit and justice.

Dinámica poblacional de Streptococcus mutans en niños de edad escolar de la provincia de Córdoba. Population dynamics of Streptococcus mutans in school age children in the province of Córdoba

La caries dental es una enfermedad infecciosa, crónica y trasmisible, que se caracteriza por la desmineralización de los tejidos duros del diente, producida por la acción de los ácidos resultantes de la actividad metabólica del biofilm desarrollado sobre los dientes. Si bien, la etiología de la caries sería polimicrobiana, los estreptococos del grupo mutans son señalados como los principales protagonistas en el inicio de la lesión cariosa. En la pared celular se destacan proteínas que participan en procesos de adhesión, agregación y co-agregación, además de polisacáridos que muestran distintas especificidades antigénicas, lo que permite distinguir cuatro serotipos: c, e, f y k. Es escasa la información de las características antigénicas de las cepas circulantes de estreptococos del grupo mutans y se desconoce la relación de las mismas con la actividad de caries. En este estudio nuestros objetivos son identificar y caracterizar fenotípica y genotípicamente las cepas de estreptococos del grupo mutans circulantes en la provincia de Córdoba. La población de estudio estará constituida por escolares, urbano–marginales de la capital y del interior de la provincia. Se determinarán los serotipos de las mismas a través de de amplificaciones por PCR de tipo multiplex y luego se secuenciarán 8 genes a través de la técnica de tipado multilocus, con el fin de realizar estudios de sistemática molecular, y de estimar la estructura genética de S. mutans. Una vez que se hayan caracterizado los patrones de diversidad y distribución geográfica de S. mutans del centro de Argentina, se intentará dilucidar cómo se relacionan la diversidad genética con la experiencia de caries de los niños del estudio. Se analizarán de forma conjunta nuestros resultados con los publicados por otros autores. De esta forma se logrará una mejor comprensión de los factores históricos y ecológicos que han moldeado su distribución y aportar conocimientos a la sistemática del grupo “mutans” en relación a otras bacterias del género Streptococcus. Dental caries is an infectious, chronic and transmissible disease, characterized by demineralization of the hard tissues of the teeth, produced by the action of acids resulting from the metabolic activity of biofilm developed on the teeth. Although the etiology of caries would be polymicrobial, the streptococci of the mutans group are identified as the major responsible in the initiation of the carious lesion. In the cell wall there are proteins involved in adhesion, aggregation and co-aggregation processes, as well as polysaccharides that present different antigenic specificities, which allow the distinction of four serotypes c, e, f and k. There is little information about the antigenic characteristics of the Streptococcus mutans strains and the relationship of those characteristics with the caries activity is unknown. In the present study our goals are to identify and characterize the phenotypic and genotypic strains of streptococci of the mutans group circulating in the province of Cordoba. The study population will consist of urban and rural scholar children from Cordoba city and from the interior of the province. In order to study the molecular systematic, and the genetic structure of S. mutans, different serotypes will be determined by multiplex PCR amplifications and eight genes will be sequenced by using the multilocus typing technique. Once the diversity and the geographical distribution patterns of S. mutans from the center of Argentina is characterized, we will attempt to clarify how the genetic diversity is related with the caries experience in the children of the study. Our results will be analyzed together with those published by other authors. This will achieve a better understanding of the historical and ecological factors that shaped the bacteria’s distribution and will contribute to the knowledge of the systematic of the mutans group in relation to other bacteria of the genus Streptococcus.

The long run relationship between stock prices and goods prices: new evidence from panel cointegration

We examine the long run relationship between stock prices and goods prices to gauge whether stock market investment can hedge against inflation. Data from sixteen OECD countries over the period 1970-2006 are used. We account for different inflation regimes with the use of sub-sample regressions, whilst maintaining the power of tests in small sample sizes by combining time-series data across our sample countries in a panel unit root and panel cointegration econometric framework. The evidence supports a positive long-run relationship between goods prices and stock prices with the estimated goods price coefficient being in line with the generalized Fisher hypothesis.

Cultura i Societat en la guerra del Francès

Des de que començà aquest projecte, el grup de recerca ha intentat aprofundir el coneixement de la Catalunya de la Guerra del Francès (1808 -1814) a partir d’una òptica britànica. El grup pretenia així desenvolupar la relació que es va establir entre els catalans i els britànics al llarg de tota la guerra, des dels primers contactes permesos per la presència de la flota britànica en la costa catalana fins a la intervenció de forces britàniques en territori català. D’aquesta manera, i primerament, el grup inicià la consulta de les bases de dades i catàlegs catalans i britànics per a completar el nostre llistat de referències arxivístiques i bibliogràfiques. El segon pas van ésser les tres estades d’investigació que entre el 2006 i el 2007 es van fer a Anglaterra, principalment a Londres. La investigació es realitzà a la British Library, al Institute of Historical Research of the School of Advanced Studies de la University of London, al National Maritime Museum i als National Archives of the United Kingdom. A continuació, el grup analitzà la informació recollida de la lectura de fonts primàries i bibliogràfiques en aquests centres de recerca. Finalment, el grup creu que la intensa relació que es va establir entre les dues parts, reflecteix la importància que les autoritats britàniques van donar a Catalunya, i que el seu aïllament amb el centre polític del bàndol patriota va permetre que desenvolupés les seves pròpies dinàmiques i cronologies, encara que s’integraven en el desenvolupament general de la guerra.

The Relationship between Teachers and Students in the Classroom: Communicative Language Teaching Approach and Cooperative Learning Strategy to Improve Learning

The aim of this research is to to investigate how a supportive relationship between teachers and students in the classroom can improve the learning process. By having a good relationship with students, teachers can offer to students chances to be motivated and feel engaged in the learning process. Students will be engaged actively in the learning instead of being passive learners. I wish to investigate how using communicative approach and cooperative learning strategies while teaching do affect and improve students’ learning performance. To achieve these goals qualitative data collection was used as the primary method. The results show that teachers and students value a supportive and caring relationship between them and that interaction is essential to the teacher-student relationship. This sense of caring and supporting from teachers motivates students to become a more interested learner. Students benefit and are motivated when their teachers create a safe and trustful environment. And also the methods and strategies teachers uses, makes students feel engaged and stimulated to participate in the learning process. The students have in their mind that a positive relationship with their teachers positively impacts their interest and motivation in school which contributes to the enhancement of the learning process.

School Choice and Student Screening in the Chilean Educational System: Who Chooses Whom?. The Case of the Catholic Education

The student´s screening made by schools corresponds to a regulatory mechanism for school inclusion and exclusion that normally overlaps the parental expectations of school choice. Based in "Parents survey 2006" data (n=188.073) generated by the Chilean Educational Ministry, this paper describe the parents reasons for choosing their children's school, and school´s criteria for screening students. It concludes that the catholic schools are the most selective institutions and usually exceed the capacity of parental choice. One of the reasons to select students would be the direct relationship between this practice and increasing the average score on the test of the Chilean Educational Quality Measurement System (SIMCE).

Identidad nacional, lengua y escuela = National identity, language and school

La globalización cuestiona la existencia de una relación mimética entre ciudadanía y Estado-nación. Las identidades homogéneas, sustentadas ideológicamente en nociones como «lengua nacional», plantean problemas en sociedades en las que ha crecido espectacularmente la diversidad lingüística e identitaria. Cataluña es un territorio en el que una parte de la población afirma una identidad catalana distinta a la española y viceversa. Además, se ha teorizado que la identidad catalana y la lengua catalana coexisten mutuamente. Por eso, se suceden voces que defienden la presencia del catalán en la educación escolar como fuente de la identidad nacional catalana, mientras que otras voces defienden su presencia simplemente como una buena manera de aprender el catalán cuando no se puede aprender en el medio social y familiar. En los últimos años, Cataluña ha recibido casi un millón de personas extranjeras que han modificado notablemente su situación sociolingüística. Las últimas encuestas manifiestan que un 6,3% de la población utiliza habitualmente una lengua distinta del catalán y del castellano. En este marco, mostramos las construcciones identitarias de un grupo de adolescentes de origen extranjero que están en el segundo ciclo de la ESO. Los datos fueron recogidos mediante dos grupos de discusión de seis-siete estudiantes de distinto origen, lengua propia y tiempo de residencia en Cataluña. Los resultados muestran la importancia del lugar de origen en la construcción de la identidad. Además, los participantes que afirman sentimientos catalanes o españoles no los relacionan con la lengua sino con los intercambios sociales que han establecido con sus iguales de origen naciona. Las intervenciones muestran también las dificultades para promover identidades múltiples desde el contexto escolar que eviten actitudes racistas y xenófobas y sirvan para promover proyectos colectivos de futuro en los que se pueda vivir desde una cierta diferencia
