Glokale Literatur im (Deutsch-als-) Fremdsprachunterricht
Authors: Rösch Heidi
Published: May 2017

Anhand konkreter Beispiele wird das Konzept glokaler Literatur skizziert und gezeigt, wie sich damit im Fremdsprachenunterricht arbeiten lässt. Dabei werden deutschsprachige und internationale Werke und ihre Übersetzungen einbezogen. Glokalität wird darüber hinaus als literaturdidaktischer Ansatz im Kontext von Inter- und Transkulturalität entfaltet und mit postkolonialer Theorie in Verbindung gebracht.

Glokal verweist auf die Wechselwirkung zwischen globalen und lokalen Handlungen und Entwicklungen, Ideen und Entscheidungen (vgl. Schubert/Klein 2011) und nimmt im Kontext politischer Bildungsarbeit weltweite und innergesellschaftliche Machtverhältnisse in den Blick. Es stellt eine Fokussierung des globalen Lernens auf die Reflexion von Interdependenzen zwischen dem Globalen und dem Lokalen dar, wozu auch die historisch entstandenen und bis heute nachwirkenden Verflechtungen der Kolonialisierung als einer frühen Form heutiger Globalisierung bis hin zur Gestaltung eines nicht-pseudo-paternalistischen, gegenüber westlicher Hegemonie kritischen Nord-Süd-Dialogs gehören.

Bezogen auf Literatur ergibt sich daraus eine kritische Reflexion des mit dem Begriff der Weltliteratur verbundenen Konzepts einerseits und andererseits des Umgangs mit Literatur im Fremdsprachenunterricht, der MI(S)T-kulturelle Ansätze (s.u.) mit globalem Lernen verbindet.

Published: May 2017

This paper investigates the inverse scattering problem for a discrete Dirac system on the entire line with coefficients that stabilize to zero in one direction. We develop an algorithm for solving the inverse problem of reconstruction of coefficients. We derive a necessary and a sufficient condition on the scattering data so that the inverse problem is uniquely solvable.

Published: May 2017

The significance of researches in modeling of boiler design and its optimization is high for saving energy and minimizing emissions. Modeling the boiler plant with all demands is rather challenging. A lot of techniques are reported in the literature for enhancing the boiler efficiency. The neural network scheme has been proved for the boiler design, and it provides a framework for the non-linear system models. In this paper, a hybrid of artificial neural network and firefly algorithm is proposed. The proposed modeling technique is simulated in MATLAB, and the experimentation is carried out extensively. The performance of the proposed modeling technique is demonstrated using type I and II error functions, followed by performing higher statistical measures such as error deviation and correlation analysis. Comparative analysis is made to substantiate the superiority of the proposed modeling technique.

Published: May 2017

With all of our present knowledge, high technology diagnostic equipment, electronic databases and other available supporting resources, detection of fetal syndromes is still a challenge for healthcare providers in prenatal as well as in the postnatal period. Prenatal diagnosis of fetal syndromes is not straightforward, and it is a difficult puzzle that needs to be assembled and solved. Detection of one anomaly should always raise a suspicion of the existence of more anomalies, and can be a trigger to investigate further and raise awareness of possible syndromes. Highly specialized software systems for three- and four-dimensional ultrasound (3D/4D US) enabled detailed depiction of fetal anatomy and assessment of the dynamics of fetal structural and functional development in real time. With recent advances in 3D/4D US technology, antenatal diagnosis of fetal anomalies and syndromes shifted from the 2

Influence of nonlinear thermal radiation and viscous dissipation on three-dimensional flow of Jeffrey nano fluid over a stretching sheet in the presence of Joule heating
Authors: Ganesh Kumar K. , Rudraswamy N.G. , Gireesha B.J. , Krishnamurthy M.R.
Published: May 2017

Present exploration discusses the combined effect of viscous dissipation and Joule heating on three dimensional flow and heat transfer of a Jeffrey nanofluid in the presence of nonlinear thermal radiation. Here the flow is generated over bidirectional stretching sheet in the presence of applied magnetic field by accounting thermophoresis and Brownian motion of nanoparticles. Suitable similarity transformations are employed to reduce the governing partial differential equations into coupled nonlinear ordinary differential equations. These nonlinear ordinary differential equations are solved numerically by using the Runge–Kutta–Fehlberg fourth–fifth order method with shooting technique. Graphically results are presented and discussed for various parameters. Validation of the current method is proved by comparing our results with the existing results under limiting situations. It can be concluded that combined effect of Joule and viscous heating increases the temperature profile and thermal boundary layer thickness.

Authors: Badiya Pradeep Kumar , Jayakumar Tejkiran Pindi , Srinivasan Venkatesh , Ramamurthy Sai Sathish
Published: May 2017

In this work, we demonstrate for the first time the ultrasensitive detection of Hg2+ ions with femtomolar sensitivity in water samples with the use of the surface plasmon-coupled emission (SPCE) platform. The use of portable network diagnostic tools for water security and integrated water shed management is a topic of recent research interest. In this context, the current study explores Hg2+ monitoring using a rhodamine-6G (Rh6G) derivative bearing a monothiospirolactone mounted onto a SPCE substrate. Thus far, the limit of detection for mercury ions by the conventional fluorescence technique has been 0.15 nm. However, we have achieved 1 fm Hg2+ detection using silver nanoparticle-based spacer layer engineering on an SPCE sensor chip. Using this technology, a field device can be fabricated for rapid, ultrasensitive, multi-analyte detection (of contaminants) in water samples.
Solid phase extraction of uranium from phosphoric acid: kinetic and thermodynamic study
Authors: Abdel-Magied Ahmed Fawzy
Published: May 2017

There is a high interest to develop suitable solid phase extractants for uranium separation from aqueous solutions in order to reduce cost and enhance the efficiency. This paper describes solid phase extraction of uranium(VI) from aqueous phosphoric acid solution using MCM-41 based D2HEPA-TOPO organophosphorous extractants. The mixture of D2HEPA (di-2-ethyl-hexylphosphoric acid) and TOPO (tri-n-octylphosphine oxide) was impregnated into the pores of MCM-41 and the synthesized sorbent was fully characterized. The influences of different factors such as synergistic mixture ratio, phosphoric acid concentration, mixing time and temperature were investigated. The results showed that 90% of uranium(VI) extraction can be achieved within 5 min, using D2HEPA-TOPO@MCM-41 (mass ratio 2:1 w/w) from 1 M phosphoric acid containing 64 ppm of uranium at room temperature. High adsorption capacity of uranium(VI) have been achieved at the mentioned conditions. The rate constant for the chemical adsorption of uranium(VI) was 0.988 g mg‒1 min‒1 calculated by the pseudo-second order rate equation. The obtained thermodynamics parameters showed that uranium(VI) adsorption from H3PO4 is an exothermic and spontaneous process.
Would David be More Likely to Speak to Angela under National Roaming?
Authors: Basso Adriano , Crocioni Pietro
Published: May 2017

The UK Government has proposed national roaming to ensure that consumers may use rival networks in areas where their own operator does not offer (network) coverage (these are known as partial not-spots). The proposed policy aimed at increasing the likelihood of callers being able to make and receive calls. While this may raise a number of concerns in terms of possible harm to consumers, this article only focuses on one question: whether national roaming, rather than making it more likely that consumers in partial not-spots may be able make and receive calls, may achieve the very opposite outcome. This is because, under national roaming, and depending on the level of the charge, operators may have the incentive to withdraw their network coverage and roam instead. We also analyse the implications for dual coverage areas.
Desiccation-Induced Volumetric Shrinkage of Compacted Metakaolin-Treated Black Cotton Soil for a Hydraulic Barriers System
Authors: Moses George , Peter Oriola F. O. , Osinubi Kolawole J.
Published: May 2017

Black cotton soil treated with up to 24% metakaolin (MCL) content was prepared by molding water contents of −2, 0, 2, 4 and 6% of optimum moisture content (OMC) and compacted with British Standard Light (BSL) and West African Standard (WAS) or ‘Intermediate’ energies. The specimens were extruded from the compaction molds and allowed to air dry in a laboratory in order to assess the effect of desiccation-induced shrinkage on the compacted mix for use as a hydraulic barrier in a waste containment application. The results recorded show that the volumetric shrinkage strain (VSS) values were large within the first 10 days of drying; the VSS values increased with a higher molding of the water content, relative to the OMC. The VSS generally increased with a higher initial degree of saturation for the two compactive efforts, irrespective of the level of MCL treatment. Generally, the VSS decreased with an increasing MCL content. Only specimens treated with a minimum 20% MCL content and compacted with the WAS energy satisfied the regulatory maximum VSS of 4% for use as a hydraulic barrier.
Method for the Accelerated Testing of the Durability of a Construction Binder using the Arrhenius Approach
Authors: Fridrichová Marcela , Dvořák Karel , Gazdič Dominik
Published: May 2017

The single most reliable indicator of a material’s durability is its performance in long-term tests, which cannot always be carried out due to a limited time budget. The second option is to perform some kind of accelerated durability tests. The aim of the work described in this article was to develop a method for the accelerated durability testing of binders. It was decided that the Arrhenius equation approach and the theory of chemical reaction kinetics would be applied in this case. The degradation process has been simplified to a single quantifiable parameter, which became compressive strength. A model hydraulic binder based on fluidised bed combustion ash (FBC ash) was chosen as the test subject for the development of the method. The model binder and its hydration products were tested by high-temperature X-ray diffraction analysis. The main hydration product of this binder was ettringite. Due to the thermodynamic instability of this mineral, it was possible to verify the proposed method via long term testing. In order to accelerate the chemical reactions in the binder, four combinations of two temperatures (65 and 85°C) and two different relative humidities (14 and 100%) were used. The upper temperature limit was chosen because of the results of the high-temperature x-ray testing of the ettringite’s decomposition. The calculation formulae for the accelerated durability tests were derived on the basis of data regarding the decrease in compressive strength under the conditions imposed by the four above-mentioned combinations. The mineralogical composition of the binder after degradation was also described. The final degradation product was gypsum under dry conditions and monosulphate under wet conditions. The validity of the method and formula was subsequently verified by means of long-term testing. A very good correspondence between the calculated and real values was achieved. The deviation of these values did not exceed 5 %. The designed and verified method does not also consider the influence of other effects, for instance, chemical corrosion or corrosion caused by frost-thaw cycles. However, this method could be a supplementary tool applicable to the study of degradation processes and the estimation of a binder´s durability as well.

Dexamethasone and sex regulate placental glucocorticoid receptor isoforms in mice
Authors: Cuffe James S M , Saif Zarqa , Perkins Anthony V , Moritz Karen M , Clifton Vicki L
Published: May 2017

Maternal dexamethasone exposure in the mouse impairs placental development and programs adult disease in a sexually dimorphic manner. Glucocorticoids bind to different glucocorticoid receptor (GR) isoforms to regulate gene transcription and cellular signaling. We hypothesized that sexually dimorphic placental responses to glucocorticoids are due to differences in GR isoforms present in the placenta. Pregnant C57Bl6 mice were exposed to saline or dexamethasone from E12.5 until E14.5 (1 µg/kg/h) before the collection of placentae. Cytoplasmic and nuclear protein fractions were extracted from placentae of male and female fetuses for Western blot analysis of GR isoforms. Eight known isoforms of the GR were detected in the mouse placenta including the translational isoforms GRα-A, B, C and D1–3 and the splice variants GRA and GRP. The expression of GRA, GRP and each of the GRα isoforms were altered by dexamethasone in relation to fetal sex and cellular location. Placentae of female fetuses had higher GRα-A and GRP expression in the cytoplasm than males, and GRα-C was more highly expressed in the nucleus of females than that in males. Dexamethasone significantly increased the cytoplasmic expression of GRα-A, but reduced the expression of GRα-C in placentae of males. Dexamethasone increased the expression of the GRα-C-regulated genes Sgk1 and Bcl2l11, particularly in females. The cleaved caspase-3 staining in placental sections indicated GRα-C may mediate sex differences in dexamethasone-induced apoptosis. These findings may underlie the sex-specific placental adaptations that regulate different growth profiles in males and females and different risks for programmed disease outcomes in offspring.

Abstract:

Introduction: The effect of regular physical activity on health is widely recognized, but several studies have shown its key importance for heart patients. Aim: The present study aimed to define the PA % values, and to convert them into metabolic equivalent values (MET), which describes oxygen consumption during physical activity. Method: A total of seventeen patients with heart disease; 3 females and 14 males; age: 57.35 yrs ± 9.54; body mass 98.71 ± 9.89 kg; average BMI 36.69 ± 3.67 were recruited into the study. The measured values from Cardiac Resynchronisation Therapy devices and outer accelerometers (ActiGraph GT3X+) were studied over a 7-day time period. Using the two sets of values describing physical performance, linear regression was calculated providing a mathematical equation, thus, the Physical Activity values in percentage were converted into MET values. Results: During the 6-minute walk test the patients achieved an average of 416.6 ± 48.2 m. During 6MWT the measured values averaged at 1.85 ± 0.18 MET’s, and MET values averaged at 1.12 ± 0.06 per week. It clearly shows that this test is a challenge for the patients compared to their daily regular physical activity levels. Conclusion: With our method, based on the values received from the physical activity sensor implanted into the resynchronisation devices, changes in patients’ health status could be monitored telemetrically with the assistance from the implanted electronic device.

A next generation of conditional cash transfer programs
Authors: Neri Marcelo
Published: May 2017

Abstract This article evaluates the role of the Brazilian federal Conditional Cash Transfer programs (CCTs) such as Bolsa Família and Bolsa Escola during the past recent years and discusses their future. Based on previous empirical evidence based on my own work, I propose an integrated framework with two complementary perspectives. The first perspective is a goal approach based on the short term aggregated influences exerted by these programs, organized under four headings, namely: equality, prosperity, stability and sensibility. The emphasis here is to compare the results of Bolsa Família with other official programs such as BPC and Social Security benefits. The second perspective follows a means approach inspecting the microeconomic mechanisms through which CCTs operate, comparing the impacts on CCTs beneficiaries versus non-beneficiaries. Such perspective helps in dialoguing about the relevance of different CCTs attributes, and to discuss possible desirable upgrades.

Abstract Objective: The purpose of this study was to describe the high-resolution computed tomography (HRCT) findings in patients with hantavirus pulmonary syndrome (HPS). Materials and Methods: We retrospectively reviewed HRCT findings from eight cases of HPS. All patients were men, aged 19-70 (mean, 41.7) years. Diagnoses were established by serological test (enzyme-linked immunosorbent assay) in all patients. Two chest radiologists analyzed the images and reached decisions by consensus. Results: The predominant HRCT findings were ground-glass opacities (GGOs) and smooth inter- and intralobular septal thickening, found in all eight cases; however, the crazy-paving pattern was found in only three cases. Pleural effusion and peribronchovascular thickening were observed in five patients. The abnormalities were bilateral in all patients. Conclusion: The predominant HRCT findings in patients with HPS were GGOs and smooth inter- and intralobular septal thickening, which probably correlate with the histopathologic findings of pulmonary edema.
DEMOCRACIA E GLOBALIZAÇÃO: POLÍTICAS DE PREVIDÊNCIA SOCIAL NA ARGENTINA, BRASIL E CHILE
Authors: Loureiro Maria Rita
Published: May 2017

Resumo As mudanças nas políticas de previdência social na Argentina, Brasil e Chile são analisadas neste artigo à luz de duplo processo. Há, de um lado, a inserção desses países na economia global, levando-os a ajustar as suas estruturas econômicas e sociais à nova era de capital globalizado sob a hegemonia do ideário neoliberal. De outro, há a dinâmica dos fatores políticos internos, filtros através dos quais os ajustes exigidos para inserção se processam e são decantados em cada país, resultando, assim, em diferentes níveis de intensidade de reformas (mais ou menos radicais) ou, ao contrário, em políticas que exprimem diferentes graus de resistência aos ditames do capital financeiro.
Entre kratos e ethos: ética, política e história em Friedrich Meinecke
Authors: Ferreira Bernardo
Published: May 2017

Resumo O artigo aborda as relações entre ética, política e história no pensamento de Friedrich Meinecke, com ênfase no livro Die Idee der Staatsräson in der neueren Geschichte ("A ideia de razão de Estado na história moderna"), publicado em 1924. Para tanto, busca-se situar esse texto no quadro da produção historiográfica do autor e de suas filiações com a tradição do historicismo alemão. Sustenta-se que Meinecke reelabora, nesse livro, o tema das relações entre ética e política, abandonando uma perspectiva anterior que lhe permitira imaginar a convergência histórica dos dois termos no movimento de autodeterminação de um Estado nacional. A história da razão de Estado exibiria, ao contrário, uma tensão trágica entre kratos e ethos, na qual a afirmação do poder político seria uma condição e, simultaneamente, uma ameaça inevitável para as realizações do espírito e da cultura.
Shadows of doubt: the uneasy incorporation of identification science into legal determination of paternity in Brazil
Authors: Caulfield Sueann , Stern Alexandra Minna
Published: May 2017

The arrival of DNA paternity testing in the 1980s was met with great enthusiasm in the Brazilian courts. Yet, over the past two decades, Brazilian legal doctrine and jurisprudence have increasingly rejected DNA proof as the sine qua non for paternity cases. Instead, DNA paternity testing has generated mountains of litigation, as biological proof has been challenged by the argument that paternity is primarily “socio-affective”. Leading family law specialists describe this new conception of paternity as an outcome of the “revolutionary” provisions of the 1988 Constitution, which recognizes the “pluralism” of family forms in modern society and guarantees equal family rights for all children. Without denying the significance of the constitution’s dignitary framework, we show that new legal understandings of paternity represent less a paradigm shift than a continuation of longstanding historical tensions between biological and socio-cultural understandings of family and identity. In this article, we explore the development of biological and eventually genetic typing in Brazil, both of which had ties to the fields of criminology and race science. Our review suggests that techniques of biological identification, no matter how sophisticated or precise, were ineffective means for establishing identity, whether of individual personhood, as in the case of paternity, or national make-up. Instead, they became incorporated as supplemental methods into complex legal, social, and cultural decision-making around families.

Published: May 2017

Abstract The effects of the non-steroidal anti-inflammatory drugs (NSAIDs) on bone quantity and quality were investigated for years. However, there is lack of information on the impact of NSAIDs on the quality of tooth-supporting alveolar bone in absence of periodontal inflammation. Thus, the aim of this study was to evaluate histometrically the influence of a selective COX-2 NSAID (Meloxicam) on the inter-radicular bone mineral density in rats. Forty-nine adult male Wistar rats were randomly divided into four experimental groups: Subcutaneous injection of 0.9% sterile saline for 15 days (G1; n=12) and 45 days (G2; n=11); and subcutaneous injection of Meloxicam for 15 days (G3; n=13) and 45 days (G4; n=13). Mineral density was histometrically determined in the inter-radicular area of the 1st mandibular molars and data analysis performed by two-way ANOVA (a=5%). Results showed no interaction between time and treatment (p>0.05) and that meloxicam did not affect the alveolar bone density. In contrast, it was found that inter-radicular alveolar bone density increased with time (91.88±3.08% and 92.86±2.38% for groups 15 and 45 days, respectively) (p<0.05). Within the limits of this study, daily administration of a selective COX-2 inhibitor (Meloxicam) did not affect the quality of the inter-radicular alveolar bone in absence of periodontal infection.

Published: May 2017

Abstract This study evaluated the effects of three metal primers and one multi-mode adhesive system on the shear bond strength (SBS) of a flowable composite resin to nickel-chrome metal alloy (Ni-Cr). Ninety plates were cast from Ni-Cr and divided in nine groups (n=10). The surfaces were sandblasted with Al2O3 and primed with three adhesive primers: Alloy Primer (AP), Universal Primer (TP) and RelyX Ceramic Primer (CP), and a multi-mode adhesive (Scotchbond Universal, SU). The Adper Single Bond Plus (SB) and SU adhesives were also combined with adhesive primers. Control group did not have any surface treatment. The groups were: AP, AP+SB, AP+SU, TP+SB, TP+SU, CP+SB, CP+SU and SU. Composite cylinders were built on alloy surface. After 24 h, half the specimens were subjected to SBS and the other half to thermal cycling before testing. Data were analyzed by two-way ANOVA and Tukey’s test (a=0.05). Failure modes were assessed by SEM observation. Higher SBS were obtained with AP and TP combined with adhesives at 24 h and the lowest one for control group. Thermocycling reduced SBS for AP, CP+SU and SU. Combination between TP and SU resulted in the highest SBS after the thermocycling. TP groups showed all types of failures and high incidence of mixed failures. The use of AP and UP metal primers before application of SU and SB adhesive systems increased the SBS of composite to Ni-Cr. These combinations between metal primers and adhesives had the highest SBS after thermocycling.

RESUMO Este estudo observacional, quantitativo e transversal teve por objetivo avaliar a função sexual e comparar a qualidade de vida e independência funcional entre indivíduos acometidos por acidente vascular encefálico (AVE) sexualmente ativos e inativos. Estes foram previamente contatados por telefone e tiveram suas avaliações agendadas de acordo com sua conveniência. Realizou-se a aplicação de uma ficha de avaliação contendo dados sociodemográficos, hábitos de vida, saúde referida e função sexual, além do questionário abreviado de avaliação de qualidade de vida WHOQOL e da escala de medida de independência funcional. Ao avaliar 29 indivíduos, observou-se que 48,3% eram sexualmente ativos. Destes, 64,3% eram do sexo masculino e 35,7% do sexo feminino. A maioria da amostra relatou diminuição da atividade sexual após a doença (64,3%); 60% das mulheres apresentou disfunção sexual pelo quociente sexual - versão feminina -, e 77,7% dos homens apresentou disfunção erétil, avaliada pelo Índice Internacional de Função Erétil. Observou-se que os indivíduos ativos sexualmente apresentavam melhor qualidade de vida relativa ao domínio físico (p=0,035) e maior independência funcional motora (p=0,005) e cognitiva (p=0,006) quando comparados aos indivíduos que não praticavam atividade sexual. Concluiu-se que uma parcela significativa dos pacientes continua ativa sexualmente e que a prática de atividade sexual esteve associada à independência cognitiva e motora.

ABSTRACT Objective: The aim of this study is to analyze if both color and nylon fibers have an influence on microwave-cured acrylic resin properties. Methods: Rectangular and disk-shaped specimens were prepared using acrylic resins; medium pink with and without nylon fibers and colorless without nylon fibers. To obtain the rectangular specimens, a stainless steel die was used with the following dimensions: 64 X 10 x 3 mm (± 0.5mm). To obtain disk-shaped specimens, a die 50mm (±0.5mm) in diameter and 0.5mm (±0.05mm) thick was employed. They were randomized to form groups: control (colorless acrylic) and experimental (medium pink, with and without nylon fibers), with each group consisting of ten (10) specimens rectangular in shape and five (5) disk-shaped. They were analyzed in six (6) assays (izod impact strength, n=10; Knoop hardness, n=10; glass transition temperature, n=3; water sorption and solubility, n=5; degree of monomer/polymer conversion, n=1; flexural strength and flexural modulus, n=10). All variables were subjected to the analysis of variance test followed by Tukey's multiple comparison test, at a 5% level of significance. Results: The analysis of the monomer/polymer degree of conversion did not reveal any difference between the three groups of resins (medium pink, with and without nylon fibers and colorless resin); it was approximately 88%. The results did not show significant differences between the groups for each variable (p>0.05). Conclusion: The results showed that color and presence of nylon fibers in acrylic resins did not affect the properties analyzed in this study.

ABSTRACT Objective: The purpose of this in vitro study was to assess and compare the dimensional accuracy of three impression techniques: 1-step putty/light-body, 2-step putty/light-body, and the monophase technique. Methods: A partially edentulous standard stainless steel mandibular arch cast with reference points on the teeth was used to make the impressions. The anteroposterior and transverse distances were measured. All impressions were made with a polyvinyl siloxane using stock metallic (1- and 2-step putty/light-body techniques) or acrylic resin (monophase technique) trays. The monophase impressions were made using a light-body material and the 1- and 2-step putty/light-body impressions with putty and light-body materials. After impression procedures, the accuracy of each technique was assessed measuring the stone casts (n = 5) poured from the impressions using a microscope at 30x magnification and at 0.5 µm accuracy. The data were analyzed statistically using 2-way ANOVA and Tukey's test (p<0.05). Results: Stone casts made by all techniques had significantly negative linear changes (shrinkage). The anteroposterior distances showed more dimensional changes than the transverse distances. The edentulous side showed more shrinkage than the anteroposterior side. Conclusion: No differences between the impression techniques were found, but significant dimensional changes were observed.

Published: May 2017

ABSTRACT Objective: The association between self-perception in oral health, history of caries and sex was evaluated in students from São Gabriel da Cachoeira, in the Brazilian state of Amazonas. Methods: The sample was composed of 509 students enrolled in six public schools of the municipal and state education system. The epidemiological study was performed by a calibrated examiner (Kappa=0.98) using the DMF-T and dmf-t indices. Self-perception in oral health was measured using the CPQ8-10 Child Perceptions Questionnaire for children aged between 8 and 10 and the CPQ11-14 for children aged between 11 and 14, in which the domains were oral symptoms, functional limitation, emotional well-being and social well-being. Results: The significance of the associations between the variables was tested using bivariate analysis, and the associations that presented p-values lower than 0.20 (p<0.20) were tested using multiple logistic regression models, the intention being to keep those with p≤0.05. The group aged between 8 and 10 years showed a mean DMF-T of 0.82 (± 1.33) and dmf-t of 2.54 (± 2.59), whilst the group aged between 11 and 14 had a DMF-T of 2.08 (± 2.41) and dmf-t of 1.5 (± 1.77). Conclusion: Sex was the variable that most influenced the dimensions evaluated, followed by the oral condition. The presence of decayed teeth did not influence the children's self-perception about their oral health.

Associations between social skills and burnout dimensions in medical residents
Authors: PEREIRA-LIMA Karina , LOUREIRO Sonia Regina
Published: May 2017

Abstract Medical residency has been considered a stressful, overwhelming period, which can contribute to the development of burnout syndrome. Given the importance of interpersonal interactions for the professional practice of medicine, studies addressing protective factors against burnout focusing on social skills are needed. The objective of the present study was to investigate the associations between social skills and burnout dimensions in medical residents. A total of 305 residents were evaluated using the Inventário de Habilidades Sociais (Social Skills Inventory) and the Inventário da Síndrome de Burnout (Burnout Syndrome Inventory). Significant associations were found between all social skills factors and at least one burnout dimension; odds ratio results indicated a protective relationship, in which the residents with an elaborate repertoire of social skills were less likely to have indicators of burnout. Considering the fact that social skills can be learned, these results can contribute to the introduction of preventive measures.
School performance at the end of elementary school: Contributions of intelligence, language, and executive functions
Authors: DIAS Natália Martins , SEABRA Alessandra Gotuzo
Published: May 2017

Abstract There are several variables that are associated with and that can influence school performance. The present study investigated the following: 1) the relationship between school performance and intelligence, language, and executive functions; 2) explanatory models for school performance. A total of 87 students in 5th grade of elementary school, attending a public school in São Paulo State, Brazil (mean age = 9.72, standard deviation = 0.58), participated in this study. The participants were evaluated in terms of intelligence, language (phonological awareness and vocabulary), and executive functions (attention, cognitive flexibility, and working memory). Bimonthly grades were collected at the end of the school year. Results revealed significant correlations between school performance and all measures, except for attention. Students’ performance on the cognitive tests explained up to 66% of their grades. Intelligence, language, and executive functions are associated with school performance, but language and executive functions, especially cognitive flexibility, can be considered as stronger predictors of performance in 5th grade. These findings can assist in the design and implementation of intervention programs to promote these skills.
Tradição Mercantilizada: Construção de Mercados Baseados na Tradição
Authors: Dalmoro Marlon , Nique Walter Meucci
Published: May 2017

Resumo A mercantilização das sociedades contemporâneas tem sido apontada como um processo responsável pela elevação do mercado à posição de intermediário dos sistemas sociais e culturais, inclusive da tradição. Fazendo uso de um estudo etnográfico na cultura gaúcha, buscamos analisar como as práticas culturais têm contribuído para a preservação da tradição por meio de dinâmicas de mercado. Para tanto, adotamos um olhar interpretativo sobre as práticas que múltiplos agentes desempenham no mercado e o reflexo destas na mercantilização da cultura tradicionalista gaúcha. Resultados apontam a tradição como uma invenção que serve de referência cultural para a construção de um mercado por três grupos distintos de agentes: produtores, consumidores e organizadores. Esses agentes fazem uso de construções históricas, do orgulho em ser gaúcho e do vínculo identitário como referência cultural para guiar três estratégias distintas de mercantilização: tangibilização, aproximação mercadológica, e valorização da tradição. Concluímos que a mercantilização da tradição pode transformar o mercado num ambiente fecundo para a preservação de tradições culturais.

Movimentos Sociais: clichês e redes educativas no filme Queimada!
Authors: Santos Joana Ribeiro dos , Rosa Rebeca Silva Brandão , Alves Nilda
Published: May 2017

Resumo: Através das imagens e sons, tecendo diálogo com as lutas por independência política na América do século XIX, Queimada! (dirigido por Gillo Pontecorvo, Itália, 1969), nos ajuda a compreender a importância das redes educativas na tessitura dos movimentos sociais ao longo da história. A ideia de uma repetição criadora, entre os movimentos do século XIX e entre os atuais, nos auxilia a discutir como os clichês aparecem no filme e estão presentes nas nossas redes, e em formas de perceber esses movimentos. Superar esses clichês parece ser uma boa tática para recriar, no presente, tantas formas de compreender a história e tecer os movimentos sociais atualmente. Buscamos teóricos como Certeau (1994), Deleuze (2005), Castells (2013), etc.
