Occupational accidents and injuries among workers in the construction industry of Windhoek, Namibia
Authors: Nghitanwa Emma Maano , Lindiwe Zungu
Published: March 2017

The construction industry is the most dangerous industry in the word with higher prevalence of occupational accidents, injuries and diseases. There is a paucity of studies that investigate occupational accidents, injuries and diseases in the Namibian construction industry. The study was conducted to determine the magnitude of occupational accidents, injuries and diseases in the construction industry of Windhoek, Namibia. A quantitative, retrospective document review was conducted to investigate the documents for reported occupational accidents, injuries and diseases for the period of five years, from April 2011 to March 2016. Data was analysed with SPSS version 23.The study found out that occupational accidents and injuries are prevalent in the Windhoek construction industry. The study recorded the total of 37 cases of occupational accidents and injuries. Young, male construction workers are mostly sustained accidents and injuries. Labourers were mostly affected than other occupations while cut by machinery comprise the majority of the source of accidents. The most body part injured is the general body. The researchers did not find any documentation for reported occupational diseases from the construction industry of Windhoek. The researchers recommended the preventive measures to be implemented to prevent occupational accidents and injuries and enforcement of legislations on occupational accidents, injuries and diseases recording and reporting.
A method for evaluating cocaine-induced social preference in rats
Authors: M. Dingess Paige , J. Deters Morgan , A. Darling Rebecca , A. Yarborough Erin , E. Brown Travis
Published: March 2017

Drug addicts are extremely sensitive to cues that predict drug availability and exposure to these cues can facilitate drug relapse. Cues vary in their nature but can include drug-associated paraphernalia, environmental contexts, and discrete conditioned stimuli (e.g., advertisements). One cue that has recently been heavily investigated is that of social interaction. To date, it has been demonstrated that when cocaine is conditioned with social interaction, place preference for cocaine significantly increases, suggesting that the presence of social interaction during a drug-associated “high” enhances the magnitude of drug reward. When social interaction is provided in a mutually exclusive, non-drug environment though, it can serve as a preventative stimulus towards cocaine seeking. What remains unknown is whether contact with rats associated with drug experience facilitates preferential social interactions for those rats. The first step in answering this question is to determine if rats can behaviorally discriminate between drug-associated and non-drug-associated conspecifics, much like humans can differentiate their “drug-friends” from their non-drug-using friends. Using a custom social interaction chamber, in which rats were able to interact with two distinct conspecifics via holes in a boundary wall, we demonstrate that rats exhibit more interactive and investigative behavior towards a partner that was consistently present during the drug-state, than a partner that was present when the rat was “sober”. It is our hope that this protocol will contribute to the development of models designed to study social cue-induced reinstatement, and related neural substrates, and will ultimately contribute to the treatment of substance use disorders.

Authors: Semprebon Elder , Amaro Hugo Dias , Beuren Ilse Maria
Published: March 2017

Este estudo objetiva verificar a influência da procrastinação no desempenho acadêmico de discentes de Ensino Superior, considerando como variável moderadora o senso de poder. Para tal, uma pesquisa descritiva foi realizada a partir de levantamento, tendo como amostra 469 alunos respondentes dos cursos de Ciências Contábeis, Ciências Econômicas, Administração, Marketing e Turismo, matriculados em uma instituição de Ensino Superior privada. Para análise dos dados coletados aplicaram-se estatísticas descritivas, testes multivariados e modelagem de equações estruturais. Os resultados indicaram que a procrastinação exerce influência negativa e significativa no desempenho acadêmico dos discentes pesquisados (H1). Para ampliar o entendimento, realizou-se uma análise de moderação do modelo, a qual demonstrou que o efeito direto negativo encontrado ocorre em condições limitantes, já que a influência foi constatada somente entre sujeitos com baixo senso de poder (H2). Portanto, os resultados desta pesquisa contribuem para o avanço dos estudos sobre a influência da procrastinação no desempenho acadêmico, ao destacar o papel moderador do senso de poder nesta relação.

Authors: Shih Wen-Ling , Tsai Chun-Yen
Published: March 2017

This study investigated students’ perception of a flipped classroom approach to facilitating online project-based learning (FC-OPBL) in a marketing research course at a technical university. This combined strategy was aimed at improving teaching quality and learning efficiency. Sixty-seven students taking a marketing research course were surveyed. Mixed methods research was adopted along with questionnaire, semi-structured interviews, online learning notes, and online discussions to understand the students’ perception of the teaching strategy used during the learning process. Results showed that FC-OPBL may enhance students’ learning effectiveness, learning motivation, and learning interest, as well as encourage diverse development and teamwork. Finally, suggestions are proposed related to flipped classroom research and instruction.
Direct Numerical Simulation of Turbine Cascade Flow with Heat Transfer
Authors: Zhu Haitao , Wu Feng , Xu Quanyong , Shan Peng
Published: March 2017

Two- and three-dimensional direct numerical simulation (DNS) of turbine cascade flow at low Reynolds number with heat transfer are performed using high-order finite difference method. Two-dimensional laminar computation which is used to construct the initial flow of three-dimensional DNS fails to predict Stanton number on the second half of suction side where the flow is turbulent in experiment. In three-dimensional DNS, transition is triggered by periodic blow-and-suction disturbances. Numerical experiments show that phase randomness of the disturbance is not necessary to trigger the transition which can be induced by disturbances with fixed phases. In a range of time fundamental frequency of disturbance, when increasing the frequency, transition moves downstream. When time fundamental frequency is big enough, transition disappears. With fixed space phases, time phases and selected time fundamental frequency, time averaged pressure and Stanton number distributions of three-dimensional DNS coincide with the experimental datum. Averaged velocity and temperature, Root-Mean-squares (RMS) of velocity pulse，temperature pulse, Reynolds shear stress and heat flux are extracted from the DNS database. All statistics agree well with experimental and theoretical results which verify the accuracy of present database.
Dopamine Inhibition Differentially Controls Excitability of Substantia Nigra Dopamine Neuron Subpopulations through T-Type Calcium Channels
Authors: Evans Rebekah C. , Zhu Manhua , Khaliq Zayd M.
Published: March 2017

While there is growing appreciation for diversity among ventral tegmental area dopamine neurons, much less is known regarding functional heterogeneity among the substantia nigra pars compacta (SNc) neurons. Here, we show that calbindin-positive dorsal tier and calbindin-negative ventral tier SNc dopaminergic neurons in mice comprise functionally distinct subpopulations distinguished by their dendritic calcium signaling, rebound excitation, and physiological responses to dopamine D2-receptor (D2) autoinhibition. While dopamine is known to inhibit action potential backpropagation, our experiments revealed an unexpected enhancement of excitatory responses and dendritic calcium signals in the presence of D2-receptor inhibition. Specifically, dopamine inhibition and direct hyperpolarization enabled the generation of low-threshold depolarizations that occurred in an all-or-none or graded manner, due to recruitment of T-type calcium channels. Interestingly, these effects occurred selectively in calbindin-negative dopaminergic neurons within the SNc. Thus, calbindin-positive and calbindin-negative SNc neurons differ substantially in their calcium channel composition and efficacy of excitatory inputs in the presence of dopamine inhibition.

SIGNIFICANCE STATEMENTSubstantia nigra dopaminergic neurons can be divided into two populations: the calbindin-negative ventral tier, which is vulnerable to neurodegeneration in Parkinson's disease, and the calbindin-positive dorsal tier, which is relatively resilient. Although tonic firing is similar in these subpopulations, we find that their responses to dopamine-mediated inhibition are strikingly different. During inhibition, calbindin-negative neurons exhibit increased sensitivity to excitatory inputs, which can then trigger large dendritic calcium transients due to strong expression of T-type calcium channels. Therefore, SNc neurons differ substantially in their calcium channel composition, which may contribute to their differential vulnerability. Furthermore, T-currents increase excitation efficacy onto calbindin-negative cells during dopamine inhibition, suggesting that shared inputs are differentially processed in subpopulations resulting in distinct downstream dopamine signals.
Frontal-Brainstem Pathways Mediating Placebo Effects on Social Rejection
Authors: Koban Leonie , Kross Ethan , Woo Choong-Wan , Ruzic Luka , Wager Tor D.
Published: March 2017

Placebo treatments can strongly affect clinical outcomes, but research on how they shape other life experiences and emotional well-being is in its infancy. We used fMRI in humans to examine placebo effects on a particularly impactful life experience, social pain elicited by a recent romantic rejection. We compared these effects with placebo effects on physical (heat) pain, which are thought to depend on pathways connecting prefrontal cortex and periaqueductal gray (PAG). Placebo treatment, compared with control, reduced both social and physical pain, and increased activity in the dorsolateral prefrontal cortex (dlPFC) in both modalities. Placebo further altered the relationship between affect and both dlPFC and PAG activity during social pain, and effects on behavior were mediated by a pathway connecting dlPFC to the PAG, building on recent work implicating opioidergic PAG activity in the regulation of social pain. These findings suggest that placebo treatments reduce emotional distress by altering affective representations in frontal-brainstem systems.

SIGNIFICANCE STATEMENTPlacebo effects are improvements due to expectations and the socio-medical context in which treatment takes place. Whereas they have been extensively studied in the context of somatic conditions such as pain, much less is known of how treatment expectations shape the emotional experience of other important stressors and life events. Here, we use brain imaging to show that placebo treatment reduces the painful feelings associated with a recent romantic rejection by recruiting a prefrontal-brainstem network and by shifting the relationship between brain activity and affect. Our findings suggest that this brain network may be important for nonspecific treatment effects across a wide range of therapeutic approaches and mental health conditions.
German and English Bodies: No Evidence for Cross-Linguistic Differences in Preferred Orthographic Grain Size
Authors: Schmalz Xenia , Robidoux Serje , Castles Anne , Coltheart Max , Marinus Eva
Published: March 2017

Previous studies have found that words and nonwords with many body neighbours (i.e., words with the same orthographic body, e.g., cat, brat, at) are read faster than items with fewer body neighbours. This body-N effect has been explored in the context of cross-linguistic differences in reading where it has been reported that the size of the effect differs as a function of orthographic depth: readers of English, a deep orthography, show stronger facilitation than readers of German, a shallow orthography. Such findings support the psycholinguistic grain size theory, which proposes that readers of English rely on large orthographic units to reduce ambiguity of print-to-speech correspondences in their orthography. Here we re-examine the evidence for this pattern and find that there is no reliable evidence for such a cross-linguistic difference. Re-analysis of a key study (Ziegler et al., 2001), analysis of data from the English Lexicon Project (Balota et al., 2007), and a large-scale analysis of nine new experiments all support this conclusion. Using Bayesian analysis techniques, we find little evidence of the body-N effect in most tasks and conditions. Where we do find evidence for a body-N effect (lexical decision for nonwords), we find evidence against an interaction with language.
An analysis of characteristics and structures embedded in data papers
Authors: Chen Ya-Ning
Published: March 2017

Research data or datasets can be regarded as a catalyst to inspire new research by repurposing or combining existing research data, and grant applicants have been requested by funding institutions to include a data management plan as part of research project proposals. In addition to the metadata approach, data papers may mirror the scientific publication model as an alternative means of description and management of research data. However, there is not a common standard for all data papers across various communities. This study aimed to build up a common structural framework to investigate the embedded characteristics and structures of the content of data papers by using a content analysis approach, and 26 data journals from 16 publishers were selected as subject in this study. This study has proposed a common framework and further embodied a concept map (Candela et al. 2015) into more concrete components for the structure of data papers.
International degree mobility in library and information science
Authors: Hillebrand Vera , Greifeneder Elke
Published: March 2017

This study examines whether a brain drain exists in LIS and explores the patterns of geographical mobility of researchers. Brain drain or brain gain describes the migration of scientists from their home country to another. The results are based on a quantitative dataset of 877 active LIS researchers who have been involved in the 2014 to 2016 iConferences. The study reveals two alarming trends: the American LIS researchers rarely ever leave their continent and might lack international exposure. On the other hand, researchers from Asia and Europe show a high rate of mobility towards North America. In particular, the next generation of LIS researchers are currently receiving their education in North America. 94.3 % of all PhD students in the sample currently live in the US and may never return. One important pull factor seems to be the possibility of studying in English. If foreign students decide to come to Europe, they go to Ireland or the United Kingdom.
Using mobile application in foreign language learning
Authors: Ivić Vlatka , Jakopec Tomislav
Published: March 2017

The Department of English Language and Literature and the Department of Information Sciences cooperatively, for the purpose of providing additional foreign language training for their students, developed application FFOS Test Your Knowledge (FFOS TYK). TYK was realized as a mobile application for the hybrid development model which allows deployment on multiple platforms. The application is intended primarily for the students of the English language and literature, but it can also be used by other students. The application is available on mobile devices, tablets, laptops and personal computers, and via wireless internet at the faculty students have the free access to it. Each user is given the option for registration and login so that their work can be statistically monitored and ranked. Research data shows that students choose the tests dealing with problem areas, but they prefer shorter tasks when it comes to typing the words. We can conclude that the overall success is rather well distributed with the majority of students scoring around 50% or above with just a few being excellent, and also not many failing to solve the tasks well. The application gives feedback to students and ranks them anonymously. It also offers teachers the possibility to increase the number of questions in the tests and to create the new tests and monitor the success of their students.

The Euro and Central Europe (from points of view of monetary integration maturity)
Authors: Palankai Tibor
Published: March 2017

The paper discusses the frameworks and development of the introduction of the Euro in Central Europe, with a focus on pre-entry countries (Czechia, Hungary, Poland, Romania and Croatia). The main elements of monetary integration maturity are the state of real-integration (possibilities of large saving in transaction costs), meeting the criteria of functioning market economy and the single market; macro-economic stability and meeting the Maastricht criteria; and shortcomings of absorption (integration) capacities of the EU. Controversial questions are also discussed, such as requirements concerning inflation, the budget deficit or exchange rate stability. The paper argues that the countries under scrutiny show diverging courses of action and policies, public support is also unclear, and the interests of TNCs and political elites contradict each other. Cultural, legal, security or emotional factors will pay a key role in eventual adoption, and prospects also depend on the solution of the current debt and migration crises.
The moderating effects of demographics on the relationship between perceived CSR and brand loyalty in the mobile telecom sector
Authors: Moisescu Ovidiu-Ioan
Published: March 2017

The goal of the paper is to analyze the demographic discrepancies in the relationship between customers’ perceptions of corporate social responsibility (CSR) and their loyalty towards mobile telecommunication companies, within the particular socio-cultural and economic context of one of the largest national markets of Central and Eastern Europe. For this purpose, a survey was conducted among a sample of 1,464 mobile telecommunication customers from the urban areas of Romania. The findings emphasize several significant dissimilarities between gender, age, education and residence type based consumer categories in what concerns the impact of various CSR dimensions, as perceived by customers, on corporate brand loyalty. The results have practical implications for enhancing corporate brand loyalty in the regional mobile telecommunication market by outlining those CSR policies which should have priority in implementation and, especially, communication.

La bifurcación de lo contingente, Religión y Ciencia ante la crisis del agua en Chapala México 2000-2005
Authors: Alcalá Felipe Gaytán
Published: March 2017

Resumen El tema del riesgo ha sido una dimensión de la ciencia para explicar las amenazas que se derivan de las decisiones presentes, el uso de las tecnologías y sus consecuencias hacia el futuro. Por el contrario, el concepto de riesgo en el sistema de la religión parece confinado a la mera absorción de la incertidumbre cuando en realidad ella misma produce y comunica riesgos de otra manera. En el presente texto abordamos las formas en que ciencia y religión tratan el problema del agua y sus amenazas futuras para una región que depende del lago de Chapala en México. Analizamos como diversas formas de lo religioso compiten con las respuestas de la ciencia para afrontar la sequía de dicho lago. Desde la tradición católica mariana de las procesiones de una imagen de la Virgen María, hasta los rezos de las iglesias evangélicas, los rituales de un grupo indígena y la energía de grupos New Age para sanar a la madre tierra. Se busca comprender cómo la ciencia asume el riesgo y cómo la religión transforma el peligro en riesgo en la sociedad moderna, ante la probabilidad de una catástrofe ecológica.

Authors: Severo Fabiane Figueiredo , Aita Natália Tobin , Marques Laila Garcia , Silva Leandro Souza da
Published: March 2017

ABSTRACT: It has become possible to evaluate the conversion of soil organic matter (SOM) in pastures and arboreal crops due to the difference between the photosynthetic cycles of Eucalyptus (C3) and most grasses (C4). The auto analyzer method coupled to the IRMS (Isotope Ratio Mass Spectrometer) in the present study evaluated the 13C content in soil profiles of Eucalyptus plantations of different ages (2, 10 and 21 years), in natural regeneration areas and natural grazing fields, and estimated the SOM conversion of each crop type of. The initial management of all sampled areas was natural pasture. The following profile layers were evaluated: 0-5, 5-10, 10-20, 20-30, 30-40, 40-50, 50-70 and 70-90cm, and the contribution of Eucalyptus biomass over the years of farming was estimated in the SOM conversion process. After 2 years of planting Eucalyptus, the beginning of pasture carbon conversion process occurred in the surface layer (0-5cm). Ten years after planting, the process of converting organic matter by arboreal crops reached the layers up to 20cm. After 21 years of planting and in natural regeneration areas, the entire profile has already been changed by planting Eucalyptus and native tree species.

Published: March 2017

ABSTRACT: The aim of this study was to evaluate the effects of 10% copaiba oil in experimentally induced wounds in horses. Four wounds were made in the lumbar and metacarpal regions of eight adult horses. In the treatment group, the wounds received 10% copaiba oil and in the control group 0.9% sodium chloride, in the daily dressing for 21 days. The wounds were evaluated three, 7, 14, and 21 days postoperatively. No significant differences were observed between the groups. The mean lumbar wound contraction rates were 80.54% and 69.64%, for the control and treated groups, respectively. For the wounds in the metacarpal region, these averages were 44.15% and 52.48%, respectively. Under the experimental conditions of the present study, it is concluded that 10% copaiba oil has beneficial in wound healing in the equine species and suggest that copaiba oil can be used as a therapeutic possibility in equine wound therapy.

Indolent systemic mastocytosis limited to the bone: a case report and review of the literature
Authors: Pinto-Lopes Pedro , Fonseca Francisco Adao , Silva Roberto , Hafe Pedro von , Fonseca Elsa
Published: March 2017

CONTEXT Systemic mastocytosis is defined as a clonal disorder of mast cells and their precursor cells and is currently classified as a myeloproliferative neoplasm. Its clinical course has a wide spectrum, ranging from indolent disease, with normal life expectancy, to highly aggressive disease, associated with multisystemic involvement and poor overall survival. The aim of this study was to report a case of indolent systemic mastocytosis, focusing on the diagnostic challenges, with a review of the literature. CASE REPORT A 79-year-old Caucasian woman with osteoporosis was evaluated at the Emergency Department because of complaints of low back pain. Before this, she had consulted an orthopedist and had undergone some imaging examinations, namely a bone scan that revealed a “superscan” pattern. Due to her pain complaints and these test results, the patient was admitted to the Department of Internal Medicine. After undergoing several analytical tests and some additional imaging examinations to rule out some important differential diagnoses, she then underwent bone marrow biopsy, which made it possible to identify indolent systemic mastocytosis. CONCLUSION Systemic mastocytosis is a rare entity that is difficult to diagnose. Its symptoms are often unspecific and frequently ignored. Skeletal changes may be the first and only manifestation of the disease and in some cases, like this one, the diagnosis is made only after histological examination. The key point for the diagnosis is to contemplate the possibility of systemic mastocytosis.
Análises multidimensional e Bakhtiniana do discurso de trabalhos de conclusão desenvolvidos no âmbito de um mestrado profissional em ensino de Física
Authors: Nascimento Matheus Monteiro , Ostermann Fernanda , Cavalcanti Cláudio
Published: March 2017

Resumo: Neste artigo analisamos a influência do contexto de formação de um curso de Mestrado Profissional em Ensino de Física (MPEF) no desenvolvimento de seus produtos educacionais. A pesquisa consiste de uma análise quantitativa e de uma análise discursiva dos produtos desenvolvidos na forma de textos de apoio de Física clássica. A análise quantitativa indicou que a maneira como os autores dos produtos educacionais encaram os referenciais teóricos sinaliza uma concepção ingênua em relação à necessidade dessa fundamentação nos seus trabalhos. A análise discursiva evidenciou aspectos semelhantes. Poucas vezes identificamos uma articulação entre o aporte teórico, as questões-foco, o desenvolvimento, a aplicação e a avaliação do produto. Notamos que o racionalismo técnico propagado pelo curso sustenta o desenvolvimento dos produtos, influenciando tanto nas suas direcionalidade, responsividade e expressividade quanto no gênero discursivo dos trabalhos. Achados indicam também que os produtos educacionais desenvolvidos tendem a ser pouco relevantes frente às necessidades escolares.
Análise semiótico-psicanalítica de uma representação visual da burrice no ensino-aprendizagem de matemática
Authors: Lopes José Passos
Published: March 2017

Resumo: Este artigo objetiva analisar uma figura como representação visual ou signo da burrice no ensino-aprendizagem da matemática, que afetou 23 alunos de pedagogia com lembranças perturbadoras capazes de provocar falhas em seus testes de realidade. Analisaram-se dois formulários, um com associações livres da figura e outro com dissertações dos alunos, fazendo-se a leitura semiótico-psicanalítica dos dados. Os referenciais utilizados foram a teoria dos signos, com o estudo de Santaella das matrizes das linguagens e pensamento visual e verbal; as teorias dos interpretantes e da percepção de Peirce; e conceitos psicanalíticos. Os resultados apontaram uma maioria de associações referenciais opinativas. As palavras (remas) mais associadas foram burro, soma, errado, produzindo a proposição (dicissigno) opinativa: o burro soma errado. Concluiu-se que a opinião, de certa forma, expressa uma falha no teste de realidade, uma fuga de se enfrentar o desprazer que a figura causava.

Published: March 2017

Abordagens cognitivistas da comunicação profissional-paciente e dos comportamentos em saúde predominam nas intervenções para apoiar a adesão ao tratamento de HIV/Aids. Mediante uma perspectiva construcionista social da comunicação profissional-paciente e de suas experiências com o tratamento, avaliou-se a implementação de uma intervenção psicossocial individual, composta por quatro encontros e informada pelo referencial da Vulnerabilidade e dos Direitos Humanos na dimensão psicossocial do Cuidado. No conjunto dos 16 encontros (quatro com cada voluntário), avaliou-se que o processo de implementação foi "moderadamente desenvolvido". Houve dificuldades para desenvolver conversas dialógicas e decodificar sentidos das falhas de adesão em situações sociais, articuladamente aos cenários interpessoais e socioculturais. Mesmo predominando orientações e incentivos aos pacientes, também ocorreram momentos dialógicos de co-compreensão das dificuldades de adesão, em seus diferentes sentidos nas cenas de tomadas. Esta modalidade de cuidado revela-se produtiva no campo das práticas em adesão.

Resumo As relações filogenéticas entre os membros da super-ordem Paenungulata, os peixes-bois, elefantes e "hyraxes", foram investigadas, utilizando-se a seqüência de análises de aminoácidos da proteína oc A do cristalino da lente dos olhos destes animais. As análises confirmam a origem monofilética das ordens Hyracoidea, Sirenia e Proboscidea e colocam os edentatas como os mais antigos do ramo da linha principal dos euterianos, seguidos pelos Paenungulatas como ramo mais próximo. Os resultados sugerem que os peixes-bois podem estar mais próximos dos hyraxes que dos elefantes dada a presença dos 72-Leu nos hyraxes e peixes-bois, mas não nos elefantes. Evidências morfológicas indicariam uma relação mais próxima entre o elefante e peixe-boi, as quais, se verdadeira, exigirão uma retrossubstituição do 72-Leu → Val na cadeia oc A dos elefantes ou 2 substituições paralelas na 72-Val → Leu nos hyraxes e peixes-bois.

Published: March 2017

Studies to select one or more species of coverage plants adapted to Amazonian soil and climate conditions of the Amazon are a promising strategy for the improvement of environmental quality, establishing no-till agricultural systems, and thereby reducing the impacts of monoculture farming. The aim of this study was to assess the persistence time, half-life time, macronutrient content and accumulation, and C:N ratio of straw coverage in a Ultisol in northeastern Pará. Experimental design was randomized blocks with five treatments and five replicates. Plants were harvested after 105 days, growth and biomass production was quantified. After 84 days, soil coverage was 97, 85, 52, 50, and 15% for signalgrass (Brachiaria brizantha) (syn. Urochloa), dense crowngrass (Panicum purpurascens), jack bean (Canavalia ensiformes), pearl millet (Pennisetum americanum) and sunn hemp (Crotalaria juncea,), respectively. Signalgrass yielded the greatest dry matter production (9,696 kg ha-1). It also had high C:N ratio (38.4), long half-life (86.5 days) and a high persistence in the field. Jack bean also showed high dry matter production (8,950 kg ha-1), but it had low C:N ratio (17.4) and lower half-life time (39 days) than the grasses. These attributes indicate that signalgrass and jack bean have a high potential for use as cover plants in no-till agricultural systems in the State of Pará.
Firma y autoría en Budapeste, de Chico Buarque, y en Divórcio, de Ricardo Lísias
Authors: Molina Cristian
Published: March 2017

resumen En este trabajo abordo las relaciones entre firma y autoría en Budapeste, de Chico Buarque y en Dívorcio, de Ricardo Lísias. Me interesa detenerme en el gesto como borde inexpresivo que se vuelve presente en el uso de las firmas autorales que las dos ficciones realizan. Una como juego de espejos entre un ghostwriter que se vuelve reconocido en un país extranjero y Chico Buarque, cuyo impacto como escritor crece a partir de la publicación del libro. Además, me detengo en cómo la versión cinematográfica de Walter Carvalho de 2009, Budapeste, repone el mismo juego ficcional de la novela, ahora arrastrado al cine y abriendo una zona de autoría colectiva respecto de la ficción. La segunda novela, Dívorcio, de Ricardo Lísias, permite detenernos en un juego coincidente entre firma autoral, narrador y personaje, pero a partir de una devaluación de la imagen autoral que esa firma escribe. Estas dos formas me permiten repensar qué significa ser un autor y leer algunas de las condiciones de la ficción brasileña - y conosureña - del presente.

Frederico Nietzsche
Authors: Velho A. Corrêa
Published: March 2017

Resumo:Texto publicado na revista carioca Fon-fon, em 1933. Embora seja de carácter predominantemente biográfico, ainda assim o autor discorre sobre as produções de Nietzsche, julga que ele deixou uma obra inacabada e de aparência caótica. Destaca como obra prima "Assim falava Zaratustra", a qual considera de uma inigualável beleza lírica, e mesmo como um dos mais famosos poemas conhecidos em prosa.
Estudos
Authors: Barreto Lima
Published: March 2017

Resumo:Artigo publicado no diário carioca Gazeta de Notícias, em 1920. Trata-se de uma resenha sobre o livro Estudos, da autora Albertina Bertha, no qual consta um texto acerca de Nietzsche. Num primeiro momento, Lima Barreto caracteriza o espírito da autora, em seguida, procura deixar claro que suas ideias sobre o filósofo são completamente opostas as avaliações da feminista. Nessa direção, reage contra a interpretação da autora buscando responsabilizar o pensador pela guerra de 1914.

Does menopause start earlier in smokers? Evidence from the Pro-Saude Study
Authors: Mendes Paula de Holanda , Faerstein Eduardo , Junger Washington Leite
Published: March 2017

OBJECTIVES: cigarette smoking has been the modifiable risk factor most consistently associated with earlier menopause. This preliminary study based on cross-sectional data aimed to analyze the association between smoking status and age of onset of menopause in a Brazilian population. METHODS: a cross-sectional study was carried out with 1,222 female employees of Rio de Janeiro university campuses aged over 35 years who were at risk of natural menopause. A Cox proportional hazards model was used to investigate the association between smoking status and age at the onset of menopause, adjusting for education, parity and alcohol consumption. RESULTS: current smokers showed a 56% increase in the risk of menopause, being 1.8 years younger at menopause onset compared with women who had never smoked. However, no differences were observed between former smokers and women who had never smoked. The adjusted median age at menopause was 49.5 years for current smokers and 51.3 years for women who had never smoked (p<0.05). CONCLUSIONS: the results suggest a deleterious but potentially reversible effect of smoking on the age of onset of menopause, which should receive greater attention in tobacco control efforts. Longitudinal analyses of this association will be carried out in the future in a follow-up study of this population.

Justificativa e Objetivo: Dentre os agravos respiratórios, infecções agudas constituem o principal motivo de consulta e hospitalização de crianças menores de cinco anos. No Estado de Mato Grosso (MT), estas doenças foram principais causas de internações nestas crianças. Este estudo objetivou analisar a prevalência de infecção respiratória aguda (IRA) em crianças menores de dois anos em Rondonópolis (MT) entre 1999 e 2014. Métodos: Estudo transversal, descritivo, tendo como fonte de dados o Departamento de Informação do Sistema Único de Saúde, oriundos do Sistema de Informação de Saúde da Atenção Básica, alimentado pelas unidades de atenção primária à saúde. Foram utilizadas técnicas de análise de séries temporais e seus respectivos modelos, sendo que os modelos auto regressivos integrados e de médias móveis mostraram-se eficientes. Após escolha do modelo que melhor representou os dados, adotaram-se critérios de escolha de modelos, como Critério de Informação de Akaike, Critério de Informação Bayesiano e o Erro Quadrático Médio de Previsão, procedendo-se com a previsão dos casos para os próximos anos. Resultados: As ocorrências de IRA são sugestivas de elevada prevalência nestes anos. Foram registrados um total de 83.465, com média anual de 5.216,56 casos. Os anos de 2001 e 2002 apresentaram os maiores números de casos: 9.458 e 8.137, respectivamente. Já 2014, apresentou o menor número de casos (1637). Conclusão: Houve redução no número de casos de IRA ao longo dos anos, fato que pode ser explicado por melhor qualidade da assistência à saúde, executando ações de promoção de saúde e prevenção desta doença.
Persistence of Baroque Trauerspiel in Tom Stoppard’s Rosencrantz and Guildenstern Are Dead as a Postmodern Literature: Rejection of Metanarrative
Authors: Mostafalou Abouzar , Moradi Hossein
Published: March 2017

Metanarrative is a conventional style of narration in literature which features tragedy in Greek model’s sense. In this type, metanarrative follows the conventions set by Aristotle; these conventions range different ones; time, one of the most important elements of narration, is linear. Therefore, in this regard, tragedy follows succession of events based on chronological orders. Moreover, metanarrative signifies stability of human deeds and meanings; therefore, what human beings do or say is stable and truthful. Moreover, in metanarrative, death is considered to be the ceasing moment of life in which continuation of life takes place in afterlife. This means that there is no ending or beginning since life is just a confusing cycle. Melancholy is used in Freudian sense that signifies suffering from hallucination and paranoia. These key concepts have composed metanarrative in conventional sense, and consequently metanarrative has been the base of tragedies in Greek sense. However, by emergence of Benjamin’s ideas regarding Trauerspiel, the fundamentals of metanarrative were challenged. Therefore, postmodern narrative started to take the place of conventional metanarrative, so that the ideas of time, language, melancholy, and death approached postmodern features. The failure of metanarrative and approach to postmodern literature can be traced in Tom Stoppard’s Rosencrantz and Guildenstern Are Dead  in which there is no chronological order within the play. Moreover, conveying meaning through language fails, and life as an endless cycle, dominates the whole play. Consequently, the metanarrative and tragedy genre of Tom Stoppard’s Rosencrantz and Guildenstern Are Dead can be replaced by postmodern narrative and Baroque Trauerspiel.

This study aimed at investigating the effect of Structured Academic Controversy (SAC) on English proficiency level of Iranian intermediate EFL learners within the Communicative Language Teaching (CLT) context. To this end, the Cambridge English Placement Test (CEPT) as the pre-test was administered to 90 EFL learners at Khayyam University of Mashhad, Iran. Based on the results and according to the test guidelines, only the intermediate EFL learners were selected as the final participants (N=60). Then, they were randomly divided into two groups of control and experimental, each group consisting of 30 subjects. Then, a t-test analysis was conducted to ensure that the two groups were not different in their English proficiency level before treatment. The experimental group was taught English based on a CLT syllabus supplemented by SAC techniques, whereas the control group received the same instruction but without being aided with the SAC techniques. After treatment, the participants received the same CEPT as the post-test. The t-test results for this test revealed a significant effect of SAC on the experimental group's performance on the post test, which means that SAC can play a role in EFL learners' English language proficiency improvement.
