"WHAT WOMEN LIKE AND WHAT MEN SEEK”: GENDER POLARIZATION IN (PSEUDO) SCIENTIFIC DISCOURSES

This study, inserted in the field of Language and Gender, investigates the reproduction of gender polarization in (pseudo) scientific discourse. In order to do so, we first analyzed a workshop proposal for a research event at a renowned higher education institution in Brazil entitled “What women like and what men seek: the neurobehavioral basis of passion”. In order to have a more contextualized understanding of such workshop, we also looked into the curriculum of the researcher who proposed it (which is available in the Brazilian Lattes platform) as well as a personal blog in which he writes about relationships and his views on related issues. Departing from an analysis grounded on theories of Language and Gender (FAIRCLOUGH, 1995, 2003; CAMERON, 1998; WODAK, 1997), our purpose is to problematize the ways in which scientific discourse may function so as to reinforce gender binarism and gender stereotypes. Indeed, it is possible to conclude that the texts not only reproduce gender polarization but also seem to work to maintain the heterosexual market(BING; BERGVALL, 1996). Moreover, the problem of gender polarization in scientific discourses seems to be related to another kind of binarism: the division between hard sciences and soft sciences. 

Sensibility and taste alterations after impacted lower third molar extractions. A prospective cohort study

Objectives: To determine the incidence, severity and duration of lingual tactile and gustatory function impairments after lower third molar removal. Study Design: Prospective cohort study with intra-subject measures of 16 patients undergoing lower third molar extractions. Sensibility and gustatory functions were evaluated in each subject preoperatively, one week and one month after the extraction, using Semmes-Weinstein monofilaments and 5 different concentrations of NaCl, respectively. Additionally, all patients filled a questionnaire to assess subjective perceptions. Results: Although patients did not perceive any sensibility impairments, a statistically significant decrease was detected when Semmes-Weinstein monofilaments. This alteration was present at one week after the surgical procedure and fully recovered one month after the extraction. There were no variations regarding the gustatory function. Conclusions: Lower third molar removal under local anesthesia may cause light lingual sensibility impairment. Most of these alterations remain undetected to patients. These lingual nerve injuries are present one week after the extraction and recover one month after surgery. The taste seems to remain unaffected after these procedures

Imagej's contribution to left ventricular segmentation in myocardial perfusion imaging

Introduction: The Myocardial Perfusion Imaging (MPI) is a non-invasive image test that allows the assessment of perfusion, function, and viability of the Left Ventricle (LV). The quantitative parameters obtained post-reconstruction requires an accurate segmentation of the LV. ImageJ is an open-source software that provides segmentation techniques that may contribute to the segmentation of the LV in the MPI. The purpose of this study was to study the influence of the different segmentation methods provided by ImageJ, in MPI, depending on the administered activity. Material and methods: We carried out an experimental research with 4 MPI studies simulated with 275, 385, 500 and 750 Bq/voxel in the myocardium, whose short-axis (SA) slices were segmented with ImageJ by the threshold default, OTSU, and k-means Plugin Toolkit methods (k=2, k=3). To analyze the most appropriate segmentation method, the signal-to-noise ratio (SNR) for each short-axis (SA) slice was calculated, in accordance with the slices obtained from the software Quantitative Perfusion Single Photon Emission Computed Tomography® (QPS®) and by manual segmentation using ImageJ. To analyze the SNR with ImageJ and QPS® segmentation methods in the same simulated study, and to compare with the same segmentation method in different simulated studies, the Friedman and Kruskal-Wallis tests were applied. Results and discussion: The method k-means with k=3 is the most suitable method for the segmentation of the LV, regardless of the administered activity. Conclusion: This study may contribute to the clinical implementation of open-source based segmentation methods of the LV in MPI, according to the activity in the myocardium.info:eu-repo/semantics/publishedVersio

Does the structure of the test affect the performance of students? Evidences from the Enem (2016)

Este artigo analisa o impacto da posição em que as questões são apresentadas sobre o desempenho dos estudantes no Exame Nacional do Ensino Médio (Enem) no Brasil em 2016. A partir de uma amostra de 4.427.790 casos, calculamos o índice de acerto por questão para os diferentes cadernos de prova da área de Matemática e suas Tecnologias. Os resultados indicam a presença do efeito fadiga na prova do Enem 2016, ou seja, a ordem de apresentação das questões afeta a proporção de respostas corretas, que diminui à medida que o item é apresentado mais próximo do final da prova. As evidências exploratórias também sugerem que o efeito fadiga se manifesta tanto em estudantes de baixo quanto de alto desempenho. Por exemplo, a posição do item reduziu o índice de acerto em até 18 pontos percentuais, controlando pelo nível de desempenho. Este artigo faz a primeira avaliação empírica do efeito fadiga no Enem e os resultados representam uma contribuição para a literatura sobre influências não cognitivas em avaliação e são úteis para fundamentar estudos mais sistemáticos sobre o impacto do efeito fadiga em testes padronizados de larga escala, inclusive para além do caso específico analisado. Ao final, sugerimos medidas que podem mitigar esse efeito no Enem.This paper analyzes the impact of the position of questions on students’ performance on the National Secondary Education Examination (Enem) in 2016. From a sample of 4,427,790 cases, we calculated the hit rate per question for the different workbooks in the Mathematics and its Technologies test. The results indicate presence of the fatigue effect on the 2016 Enem, that is, the order in which the questions are presented affects the proportion of correct answers, which is diminished as an item is presented closer to the end of the test. The exploratory evidence also suggests that the fatigue effect is manifested in students of both low and high performance. For example, the position of an item reduced the hit rate up to 18%, controlling for performance level. This paper conducts the first empirical evaluation of the fatigue effect during the Enem. The results contribute to the literature on the non-cognitive influences in evaluation, being useful to substantiate more systematic studies on the fatigue effect’s impact on large-scale standardized tests, beyond the case analyzed. At the end, we suggest measures that can mitigate this effect during the Enem

Intentional Replantation as Treatment of Extrusive Luxation: A Case Report

Accurate diagnosis, immediate care and proper treatment planning are important factors for the successful treatment of dental traumatic injuries. In extrusive luxation, postponement in treatment may lead to the need for new strategies for the resolution of unwanted consequences. The present case report describes an unusual condition of delayed treatment regarding extrusive luxation of two anterior teeth treated by intentional replantation. An 18-year-old female patient attended the Dental School for the treatment of a traumatic injury to the anterior teeth 5 days after a fall from a bicycle. Clinically, teeth #21 and #22 were extruded in incisal edges for 5 mm from their neighboring teeth, had edematous gingiva, showed grade II mobility and were painful to percussion. Radiographically, the roots were intact and the periodontal ligament space was thickened along its entire length. As immediate repositioning could not be performed, intentional replantation was recommended. After detaching the periodontal ligament, the teeth were extracted and the alveolus was curetted and irrigated with saline solution to remove the already-formed clot. After replantation, the teeth were restrained and the patient was medicated with antibiotics as well as analgesics. After 10 days, the splint was removed, the root canals were instrumented and then, filled with calcium hydroxide. After 30 days, they were completely obturated using gutta-percha. The 5-year follow-up showed root integrity, absence of mobility and normal periodontium. The outcomes of the current case report revealed that when intentional replantation was properly conducted, it could be considered an option for the treatment of extrusive luxation where the teeth were not to be immediately repositioned

MERCADO FUTURO DE SOJA NA BMFE CBOT: UMA ANÁLISE NO PERÍODO DE 2005 A 2007

O presente trabalho busca calcular a base e o risco de base, razão ótima e eficiência do hedge da soja brasileira comercializada através dos contratos da Bolsa de Mercadorias e Futuros (BMF) e contrato de soja Latino-Americana da Chicago Board of Trade (SA-CBOT) e contrato de soja da Chicago Board of Trade (CBOT). O valor médio da base e o risco de base foram calculados na semana de vencimento dos 50 contratos considerados no periodo entre janeiro de 2005 a julho de 2007. O método adotado no cálculo da base é está em acordo com Hull (2005); o risco de base e a efetividade de hedge são propostos por Silveira (2002); Myers; Thompson (1989) estabelecem a motodologia para o cálculo da razão ótima. Do procedimento adotado neste, foram possivel observar os seguintes resultados: i) os menores valores médios da base foram em Paranaguá (em todas as bolsas). ii) apesar de possuir os menores valores médios de base, a CBOT apresentou maior risco de base que a BMF. Tanto o Mercado Futuro de soja da BMF quanto o mercado da CBOT, mostraram-se eficientes. Porém, não foi possível afirmar com precisão que o mercado futuro SA-CBOT é eficiente. A razão de hedge mostrou-se elevada, variando entre 87,20% - 64,77% (para BMF). A razão de hegde da soja em Illinois apresentou-se consideravelmente maior que as demais quando comercializada na CBOT. Conclui-se assim, que sojicultores brasileiros possuem, de maneira geral, melhor instrumento de proteção ao risco de preço quando comercializam na BMF.---------------------------------------------This dissertation analyses the hedge soybeans operations by using BMF and CBOT`s contracts, and considering Paranagua (PR), Sorriso (MT), Barreiras (BA) and Cascavel (PR). Initially, it was calculated the basis risk from the hedge operations in the ending week of each contract. It was considered transactions between BMF, CBOT and SA-CBOT (South America Soybeans Contract). It was also calculated the optimal hedge ratio by Myers; Thompson (1989) methodology. During January 2005 and July 2007, these exchanges had commercialized 50 contracts. this paper reaches the following results: i) the lower basis’ average was in Paranagua (considering all stock exchanges); ii) CBOT had smaller basis’ average but greater basis’ risk then BMF. On the second step of this analysis, both BMF and CBOT were considered efficient. However, the same result was not observed on SA-CBOT, which wasn’t possible to precise about its efficiency. The optimal hedge ratio (OHR) was high to BMF (87.20% - 64.77%). The OHR to Illinois was the greatest, 93.41% when commercialized with CBOT. This number is consistent with Dorfman; Sanders (2006). However, CBOT presents lower OHR whenever we consider the Brazilians places in this study (55.88% - 35.7%). We conclude that Brazilians soybeans’ farmers which want to protect against price in future market have a better tool by commercializing with BMF that CBOT or SA-CBOT.Mercado Futuro, Soja, Hedge, Future Markets, Soybean, Crop Production/Industries, Marketing,
