Published: July 2020

This article reports on the first three phases (exploration, identification, and planning) of a collaborative action research study whose main objective was to transform the pedagogical practices of teachers of a Colombian school of foreign languages. A methodology of collaborative action research and techniques, such as direct observation, completion of a reflection journal, and surveys and interviews with teachers and students was employed. Findings showed that the participants managed to identify some of the major problems they faced within their pedagogical practices and to design and implement courses of action to overcome them. Upon completion, favorable perceptions about the impact of collaborative action research on the transformation of the participating English language teachers’ pedagogical practices could be evidenced.
Profiles of Students in Bilingual University Degree Programs Using English as a Medium of Instruction in Spain
Authors: Madrid Daniel , Julius Steven
Published: July 2020

This is an empirical study which aims to examine the profile of Spanish university students in bilingual degree programs that employ English as a medium of instruction by utilizing the bilingual section of the teaching degree course at the University of Granada as a sample. To this end, a questionnaire was applied to 216 students. While 75% of the students reported having problems when following a bilingual class, these difficulties were found to diminish or disappear after the first trimester. The majority of the students (70%) were satisfied with the program offered but they also detected some deficiencies, which provided a basis for various suggestions as to how university bilingual programs might be improved.
Needs Analysis to Enhance English Language Proficiency at a Mexican University
Authors: Garcia-Ponce Edgar Emmanuell
Published: July 2020

This study examines the perceptions of employers, university authorities, English teachers and students concerning needs to promote English achievement in a Mexican university. By drawing on data collected from focus groups and questionnaires, the evidence suggests that there are several needs which hinder the attainment of English objectives in this higher education context. To address this, the participants’ perceptions are reformulated into a set of recommendations which might be beneficial for this context and other higher education institutions which seek to develop English language competencies in university students. The relevance of this study is that it shows how needs analysis can be used in higher education as a tool to identify needs and formulate context-sensitive solutions for enhancing English achievement.
English Language Teachers’ Oral Corrective Preferences and Practices Across Proficiency Groups
Authors: Sepehrinia Sajjad , Fallah Nahid , Torfi Soad
Published: July 2020

Studies on oral error correction in second language acquisition have been tilted towards cognitive aspects ignoring the affective and practical dimensions. This study attempted to fill this gap by investigating the role of students’ proficiency levels in five English language teachers’ corrective behavior. Follow-up interviews were conducted with the observed teachers. The results showed that the teachers provided more corrections to less proficient learners though they preferred more correction for advanced learners and used mainly recast for both groups, avoiding explicit forms of correction. They were mainly concerned with the affective aspects of oral error correction and acted on their own value system and teaching experience. The findings carry important implications for teacher education programs and the studies in this regard.

Spatial and spatiotemporal clustering of the COVID-19 pandemic in Ecuador
Authors: Ballesteros Patricia , Salazar Emily , Sánchez Diana , Bolanos Carlos
Published: July 2020

Introduction: In Ecuador, the first COVID-19 case, the disease caused by the SARS-CoV-2 virus, was officially reported on February 29, 2020. As of April 2, the officially confirmed numbers of COVID-19 cases and deaths from it were 3 163 and 120, respectively, that is, a mortality rate of 3.8%. Objective: To identify spatial and spatiotemporal clusters of COVID-19 cases officially confirmed in Ecuador. Materials and methods: Case series study. An analysis of all COVID-19 cases officially confirmed in Ecuador from March 13, 2020 to April 2, 2020 was performed. Relative Risk (RR) of COVID-19 contagion was determined using the discrete Poisson distribution model in the SaTScan software. Clusters were generated using purely spatial and spatiotemporal scan statistics. Significance of each cluster was obtained through 999 iterations using the Monte Carlo simulation, obtaining the most probable random model. Results: As of April 2, spatiotemporal clustering allowed identifying two clusters in Ecuador, a main cluster in the Guayas province (area: 15 430 km2; population: 3.6 million inhabitants; RR: 7.08; p<0.000001; calculated annual incidence 1700 cases / 100 000 people) and a secondary cluster in the Pichincha province (area: 88 904 km2; population: 7.1 million; RR: 0.38; p<0.000001; calculated annual incidence 737 cases / 100 000 people.) Conclusions: The implementation of COVID-19 mitigation strategies should be focused on areas of high transmission risk; therefore, spatial, and spatiotemporal clustering with SaTScan can be extremely useful for the early detection and surveillance of COVID-19 outbreaks.
Social integration as a significant factor in the rehabilitation of people with disabilities in a neuropsychiatric boarding school
Authors: Nevelichko Lyubov
Published: July 2020

The article describes the experience of social rehabilitation of persons with mental disorders and central nervous system living in a neuropsychiatric boarding school. It has been established that modern rehabilitation practices aimed at developing or restoring lost skills of patients is not a program limited to a specific time period, but a long continuous process that requires constant monitoring and corrective measures. But mental diseases in the vast majority require large expenditures from the state budget, therefore, the implementation of systematic individual resocialization measures becomes extremely difficult, and subsequent work with the mentally ill is reduced to meeting the basic life needs of the disabled, assigning them the role of recipients of guardianship and care. It is justified that social rehabilitation programs aimed at developing or restoring the necessary skills, as well as activating compensatory mechanisms, do not fully fulfill the socializing function without forming the individual and social value of the wards. The novelty of the study is to justify the prospect of including in the process of existing practice of social rehabilitation a component that can to some extent change the social status of patients in a neuropsychiatric boarding school and allow them to master new social roles – the integration of the mentally ill and society.
Speech strategies in pathoanatomic discourse: the communicative aspect
Authors: Nedostup Oleg
Published: July 2020

The relevance of the work involves the growing interest of linguists to the problem of studying medical discourse as a complex-functional communicative education. In this article, the pathoanatomic subdiscourse, being a lacunar zone in the space of medical discourse, is in focus of our attention.
The paper presents the results the author gained through the communicative-pragmatic analysis of empirical material of pathoanatomic subdiscourse fragments. The following speech strategies are described: dominant (preliminary, diagnostic, and explanatory) and complementary (pragmatic, dialogical, and rhetorical). The functions of the preliminary and diagnostic strategies are aimed at intra-medical communication, while the explanatory strategy chiefly intents to build communication with the relatives of the deceased. In turn, the functions of complementary strategies are implemented as follows: a pragmatic strategy is responsible for organizing the goals in terms of communication between the interlocutors, a dialogue strategy assumes responsibility for building a correct and accurate dialogue scenario, a rhetorical strategy allows you to effectively influence the interlocutor. These speech strategies are closely related and embedded into the communicative phenomenon of the pathoanatomic subdiscourse – a manipulative-explanatory strategy targeted to emotionally and comfortably inform the relatives of the deceased about the causes of death.
Speech strategies explicate a number of speech tactics, which are expressed through specialized and non-specialized ways of actualization.
The revealed and interpreted communicative components of the pathoanatomic subdiscourse allow us to draw the following conclusions: this subdiscourse has specific features (it is structurally and semantically mobile, historically changeable and communicatively asymmetric); actualization of the ways of executing the speech strategies that build the communicative aspect of the pathoanatomic subdiscourse is a complex communicative area of medical discourse that needs further study

Published: July 2020

ABSTRACT Objectives: to describe the Adult's perception of healthcare after Myocardium Infarction. Methods: qualitative descriptive analysis carried out with 12 adults who had myocardial infarction and conducted from February to May 2018. The research design was based on the “Consolidated Criteria for Reporting Qualitative Research”. Data collection was performed through semi-structured questionnaire, interview script and field diary. The interviews were encoded, and their content was analyzed using software support. Results: three classes were obtained: “Fear, (un) certainty and (un) awareness”; “Lifestyle and beliefs of illness” and “Health care search”. Unhealthy lifestyle habits, lack of health prevention / promotion, difficulties in accessing services and lack of knowledge about the disease generated fear and uncertainty about the future. Final Considerations: the perception of acute myocardial infarction is related to the trajectory of illness, lifestyle and the belief that the infarction only affects others.

Authors: Trovó Simone Aparecida , Cucolo Danielle Fabiana , Perroca Marcia Galan
Published: July 2020

ABSTRACT Objectives: to measure the average time spent by the nursing staff during patient admission and investigate their compliance with the activities described by the Nursing Interventions Classification; evaluate the degree of interference in the workload of the team. Methods: observational with time measurement through software. We followed 199 admissions made by the nursing staff in seven units, using two validated instruments. Total scores ≥ 70% and 50% validated the process. Results: the average time of nurses ranged from 5.5 (standard deviation = 2.3) to 13 (standard deviation = 1.1) minutes; and the auxiliary / technician, between 4.7 (standard deviation = 2.1) and 6.8 (standard deviation = 2.0) minutes (p ≤ 0.01). We qualified six admissions made by nurses and 33 by assistants/technicians. The intervention spent 16.3% to 31.5% of the working hours of the team. Conclusions: admission impacts nursing workload and needs to be considered both in the measurement of activities and in the sizing of the nursing staff.

Authors: Barreiro Reinaldo Gutiérrez , Lopes Marcos Venícios de Oliveira , Cavalcante Layana De Paula
Published: July 2020

ABSTRACT Objectives: theoretical validation of the concept of low self-efficacy in health as a nursing diagnosis construct. Methods: construction of a middle-range theory for validating diagnoses, comprised of five stages: definition of the approach for building the theory; definition of the main concepts; creation of a pictorial diagram; formulation of proposals; establishment of causal relationships and evidence for clinical practice. The main concepts were identified through a literature review and the studies were taken from the LILACS, SCOPUS, CINAHL and PubMed/MEDLINE databases. The final sample was comprised of 92 articles. Results: eighteen etiological factors and 16 clinical indicators were identified; characterized as antecedents and manifestations for inferring a diagnosis of low self-efficacy in health. Conclusions: the related concepts of the new nursing diagnosis of low self-efficacy in health, to be applied in clinical nursing practice, were identified and defined.
Access of the patient to the cancer network under the “Sixty-Day Law”: Integrative Review
Authors: Lombardo Mariela Santos , Popim Regina Célia
Published: July 2020

ABSTRACT Objectives: to analyze Brazilian scientific production on patient access to the oncology network under the “Sixty-Day Law”. Methods: integrative review of the literature in the databases Lilacs, PubMed and Scielo. The descriptors used were: neoplasms, health services accessibility, early detection of cancer. Articles published from 2015 to March 2019 were included. Results: 17 articles were analyzed and four themes emerged: inequality in access; qualification of Primary Care professionals; time as a determinant factor; information system as limiting factor. Conclusions: the access to the oncology network is unequal and there are several barriers faced by the users. A continuing education of health professionals is necessary to implement preventive strategies. Treatment initiation is late, showing non-compliance with the law. The health care network is highly fragmented, there is lack of coordination between the services and, consequently, there is a lack of patient follow-up.

Published: July 2020

Abstract This paper reports the first LIDAR measurements obtained on a fishing pier in Santa Catarina, southern Brazil. A laboratory was built to monitor the vertical structure, time and directional variability of winds in the transitional region between the ocean and the continent. A meteorological station provided pressure, temperature, wind and humidity data. Prevailing winds tend to blow from the NE along the coastline, strongly influenced by the South Atlantic Subtropical High Pressure center. Sea and land breezes had significant amplitude. The offshore wind component (sea breeze) was generally active from 11:00 to 20:00 h; the onshore component (land breeze) from 22:00 to 09:00 h. Weak vertical shear and increasing wind speeds were typically observed in the early afternoon, while stronger shear and the highest wind speeds tend to occur in the late afternoon. Winds profiles from the ocean sector were usually more intense and less sheared. The average power of wind turbines was estimated. The local resource is nearly 2.5 times greater than that of a site located 9.3 km inland. The use of coastal laboratories was demonstrated to be a cost-saving solution for long-term monitoring of the country's wind resources.
Oscilaciones Macroclimáticas que Afectan la Oferta Hídrica en la Cuenca del Río Gachaneca; Boyacá-Colombia
Authors: Beltrán Luís , Díaz Diana Cristina
Published: July 2020

Resumen Para estudiar la influencia de las oscilaciones macroclimáticas en la cuenca del río Gachaneca este trabajo estudió la variabilidad de la temperatura mínima, máxima e índices de precipitación estandarizada en la zona de la cuenca durante 1982-2015, y evaluó la relación de estas variables con El Niño Oscilación Sur (ENOS), la Oscilación del Atlántico Norte (OAN) y la Oscilación Cuasi-Bienal (OCB) mediante análisis de correlación canónica. Los porcentajes de varianza más altos explicados por las oscilaciones macroclimáticas en Diciembre-Febrero oscilan entre 34% y 38%, en Marzo-Mayo entre 15% y 20%, en Junio-Agosto entre 15% y 25% y en Septiembre-Noviembre entre 21% y 34%. En todos los casos el ENOS tiene la mayor influencia, seguido por la OAN. Durante DEF el área de estudio está más expuesta a eventos secos que aumentan el riesgo de agotamiento del recurso hídrico debido a la fase cálida del ENOS. La OAN indirectamente puede reforzar o atenuar los eventos de sequía debido a su relación con la magnitud de los vientos Alisios y la variabilidad del Atlántico tropical que tienen repercusión en la posición de la ZCIT y los procesos convectivos de la región.

Authors: Carrasco Arletis Roque , Sapucci Luiz Fernando , Mattos João Gerd Zell de , Lorenzo Maibys Sierra , Montejo Israel Borrajero
Published: July 2020

Resumo Os modelos de previsão de tempo baseiam-se em métodos computacionais aplicados para prever os fenômenos meteorológicos a partir da integração numérica de equações que descrevem o movimento dos elementos químicos que compõem a atmosfera. Entre as variáveis previstas por esses modelos a precipitação é uma das mais importantes, e é a mais difícil de se obter bons resultados no posicionamento, intensidade e extensão dos eventos. Uma das fontes de incerteza na qualidade dessas previsões é o próprio método de avaliação empregado, pois os métodos convencionais não avaliam adequadamente os aspectos espaciais. O presente estudo tem como objetivo principal propor e validar uma metodologia de avaliação diagnóstica orientada a objeto, empregando o algoritmo Method for Object-Based Diagnostic Evaluation (MODE), dentro do Sistema Comunitário de Avaliação de Modelos Numéricos de Previsão de Tempo e Clima (SCANTEC). Experimentos utilizando casos idealizados são apresentados, os quais permitem validar a implementação do método e demonstrar as suas vantagens com relação às métricas convencionais de avaliação. São também apresentados os resultados desse método na comparação das previsões reais de precipitação gerados por modelos utilizados rotineiramente no CPTEC, como prova de conceito, exemplificando o uso ao explorar as métricas disponíveis. Os resultados são discutidos e demostram o grande potencial da metodologia orientada a objeto para o aprimoramento e evolução dos produtos de previsão numérica de tempo.
Contribuições de Kraepelin, Bleuler e Bergson para a fenomenologia clínica da esquizofrenia de Minkowski
Authors: Pita Juliana , Moreira Virginia
Published: July 2020

Resumo Este artigo se propõe a apresentar a fenomenologia clínica da esquizofrenia construída pelo psiquiatra Eugène Minkowski por meio de influências teóricas sofridas a partir das ideias de Kraepelin, Bleuler e Bergson. O interesse de Minkowski ao discutir a esquizofrenia é alcançar uma delimitação dessa patologia. Por mais que se remeta constantemente a Bleuler por ter sido seu aluno, é na filosofia de Bergson que encontra uma fonte sólida para aprofundar sua discussão sobre o aspecto estrutural da esquizofrenia. Com essa influência filosófica, é possível compreender a esquizofrenia como perda de contato vital com a realidade, e não como um relaxamento de associações, conforme Bleuler destacava. Concluímos que utilizar a fenomenologia clínica da perda do contato vital com a realidade e a compreensão da esquizofrenia como perda desse contato com o mundo permite apontar um novo direcionamento para estudar esta patologia como uma patologia da intersubjetividade.

Published: July 2020

Abstract: Fish feeding habit associated to the morphology of their digestive tube can provide useful biological and ecological information. Between January and December 2012, we examined 16 fish species discarded by trawl in the Potiguar basin, northeastern Brazil, and classified them into four groups according to Alimentary Index - IAi. Our aims were to: (1) provide information on diet composition of one species represented by each group (Opisthonema oglinum, Conodon nobilis, Larimus breviceps and Sphoeroides testudineus), (2) examine the morphology of their digestive tube, and (3) associate ingested food items with the morphological features. Stomach contents were collected and classified according to IAi: main, accessory and secondary categories; fragments of esophagus, stomach, and small intestine were examined using paraffin section technique. Biometric data (total length-TL, standard length-SL and total weight-TW), stomach weight-SW, and gonadal weight-GW were recorded and applied in two indices: (1) the stomach Repletion Index - SRI (SRI = SW/TW × 100) and (2) the gonadosomatic index - GSI (GSI = GW/TW × 100) for the analyses of feeding and reproductive activities, respectively. The main food categories were (1) Teleostei for C. nobilis, (2) Crustacea for L. breviceps and O. oglinum, and (3) Mollusca for S. testudineus. The feeding activity was higher during the dry season, while the GSI was higher in the rainy season. The morphological analysis revealed a regular structure of the tissues analyzed. We highlight the presence of tubular gastric glands and strong muscular walls in the stomach (O. oglinum; L. breviceps); well-developed pyloric caecum in the intestine (O. oglinum; C. nobilis; L. breviceps); and presence of pseudo-stomach (S. testudineus). Our study confirms that the digestive tube of the examined species has morphological adequacy for carnivorous feeding habit, providing useful information on tissue structures associated to diet composition.

Published: July 2020

Abstract Background The human skin is an extremely sophisticated and evolved organ that covers the whole body. External agents or the patient’s own diseases can cause skin injuries that can challenge healthcare professionals and impose high social, economic and emotional costs. Objectives To evaluate the impact of topical nifedipine on skin wound healing, specifically on polymorphonuclear cells, vascular proliferation, and collagen. Methods We used three pigs, and created eight injuries in the dorsal region of each animal. We applied 1%, 10%, and 20% concentration nifedipine creams to four of the wounds in animals 1, 2, and 3 respectively and treated the other twelve wounds with saline solution 0.9% only. We analyzed the presence of polymorphonuclear cells, vascular proliferation, and collagen at six different times (days 1, 3, 7, 14, 21, and 28). Results The evaluation of polymorphonuclear levels showed mild cell activity at all times in the control group, while in the nifedipine groups, marked levels were more frequent at all times during the experiment. There was a 4.84-fold increase in the chance of marked vascular proliferation (p = 0.019) and, at the same time, a decrease in collagen formation (OR 0.02 / p = 0.005) in animal 3. Conclusions Topical NFD may have an impact on skin wound healing mechanisms. Our study showed that polymorphonuclear cells and vascular proliferation increased. We also demonstrated that collagen formation decreased. Therefore, topical NFD may have a positive impact on skin wound healing. Additional studies are needed to confirm our results.
Semelfactives as atomic predicates
Authors: Trebisacce Romina
Published: July 2020

ABSTRACT The goal of this paper is to provide evidence in favour of the hypothesis that, regarding their internal temporal structure, semelfactive and achievement predicates are alike (i.e., both are atomic). In order to do so, I will study the readings these predicates obtain in two different contexts: when they are modified by for-phrases and when they combine with a progressive operator. The conclusion will be that when combined with elements that operate over intervals, semelfactives trigger a special reading (the iterative one), because these elements cannot operate within their internal temporal structure.

Restorative dental treatment in times of COVID-19
Authors: GOMES Robson de Lima , PEDROSA Marlus da Silva , SILVA Claudio Heliomar Vicente da
Published: July 2020

ABSTRACT Since the outbreak of the Coronavirus Disease 2019 (COVID-19), caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), numerous restrictive measures have been adopted by governments of different countries. The return to elective dental care in Brazil is a reality even during the COVID-19 pandemic. During restorative dental procedures, the dental professional requires close contact with the patient, being exposed to contaminated saliva and fluids. In addition, transmission of COVID-19 by the generation of aerosol produced by dental handipieces may be possible. Thus, the dental staff must know how to act during restorative dental procedures, putting into practice the correct clinical protocols to avoid cross-contamination and COVID-19 spread. The purpose of this article is to review the literature on the biosafety practices especially in the context of restorative dental procedures in times of COVID-19.
Fotografia, registro sem documento
Authors: Carboni Maria Cecilia C.
Published: July 2020

Resumo Este artigo propõe pensar outra possível história que as fotografias contam sobre a Revolta de 1924, entendendo-as como diferentes narrativas sobre o evento em questão. Nesse sentido, investiga a transgressão do conceito tradicional da fotografia como documento da realidade, observando que a fotografia promove outro tipo de narrativa que vai além do registro como documentação histórica. Para tanto, o artigo fundamenta-se em conceitos e reflexões trazidos por vários autores, como Carlo Ginzburg sobre o conceito de rastro, François Dosse e Mauricio Lazzarato nas respectivas interpretações do conceito de acontecimento e Joan Fontcuberta, Vilém Flusser, Walter Benjamin e Lucrécia Ferrara que apontam outras relações entre a fotografia e a comunicação, além da bibliografia sobre a Revolta de 1924.
O artificialismo teatral e crítico de Jean Renoir em A carruagem de ouro
Authors: Mesquita Cláudia Cardoso , Oliveira Cícero Pedro Leão de Almeida
Published: July 2020

Resumo O artigo investiga o filme A carruagem de ouro (1952), dirigido por Jean Renoir, buscando identificar como as escolhas estilísticas e dramatúrgicas do diretor configuram um artificialismo teatral. A partir da análise da mise-en-scène e da dramaturgia da obra, abordamos como tal artificialismo resulta em uma perspectiva lúdica e incisiva sobre as relações sociais. O aspecto teatral do trabalho é analisado a partir de elementos formais que são mais comuns no teatro (como a frontalidade dos rostos, a desnaturalização e o aprisionamento dos espaços) ou em um cinema considerado “teatral” (como as entradas e saídas laterais), preservados pelo estilo de Renoir.
Let us try to assume our fundamental ambiguity: on the art of getting beyond identity politics
Authors: Gielen Pascal
Published: July 2020

Abstract Inspired by Antonio Gramsci, sociologist Pascal Gielen defines the last decade as one of ‘organic crisis’. In such periods many (economic, political, ecological) crisis follow each other while the hegemonic order cannot deal with them anymore in a convincing way, and a new political paradigm that can sufficiently deal with them is not yet invented. In such a period the oppositions between left and right, between different ethnic groups, or between genders start to become more black & white. That’s why Gielen thinks also identity politics is problematic, or has at least a very problematic flip side that is contra-productive for finding solutions for this crisis. Instead we need to develop a so-called ambiguity politics inspired by ambiguity aesthetics, that could deal in a better way with the problems and contradictions of this contemporary world of rambling causalities. Such a politics is based on the recognition of the Other in ourselves, and on the understanding of ourselves and our societies as fundamentally ambiguous.

Comparamos a similaridade florística entre as Bignonieae do Parque Nacional do Itatiaia e áreas próximas utilizando o coeficiente de similaridade de Jaccard e análise de agrupamento através do método UPGMA. A flora de Bignonieae de Itatiaia é mais similar a áreas de Mata Atlântica, tais como Picinguaba e Rio Doce, do que a áreas de Cerrado, como Serra do Cipó e Grão Mogol. Os resultados sugerem que a formação vegetacional é mais importante do que a proximidade geográfica na composição florística de Bignonieae em Itatiaia.

RESUMO (Flora da Usina São José, Igarassu, Estado de Pernambuco: Acanthaceae, Gesneriaceae e Loganiaceae). Acanthaceae, Gesneriaceae e Loganiaceae são bem representadas na flora Neotropical e brasileira, no entanto são famílias pouco estudadas no Nordeste do país, em especial na Mata Atlântica do Estado de Pernambuco. Dessa forma, visando contribuir com o conhecimento taxonômico acerca desses táxons, este estudo teve como objetivo identificar e caracterizar morfologicamente as espécies ocorrentes nos fragmentos da Usina São José, localizada em Igarassu, dando continuidade à série de monografias para a área. Expedições de coletas foram realizadas na área entre janeiro de 2017 e janeiro de 2018. Os espécimes depositados nas coleções dos herbários CEPEC, HST, IPA, JPB, NY, PEUFR, RB e UFP também foram analisados. Para a área de estudo, foram encontradas onze espécies, cinco de Acanthaceae, duas de Gesneriaceae e quatro de Loganiaceae. São apresentados chave de identificação, descrições, ilustrações e comentários sobre distribuição geográfica e hábitats.

Published: July 2020

RESUMO Objetivo: Analisar e relacionar a percepção dos sintomas vocais, o conhecimento de saúde e higiene vocal em cantores populares e eruditos. Método: Participaram da pesquisa 186 cantores de ambos os sexos, na faixa etária de 17 a 60 anos, divididos em: Grupo Cantores Populares (GCP) - 104 cantores populares; Grupo Cantores Eruditos (GCE) - 82 cantores eruditos. Todos os participantes responderam a três instrumentos: o questionário de autoavaliação vocal, a Escala de Sintomas Vocais (ESV) e o Questionário de Saúde e Higiene Vocal (QSHV). Resultados: O maior número de participantes foi do sexo feminino. Os cantores eruditos apresentaram maior tempo de aula de canto. Horas de shows de 1-2 horas foi maior em número de sujeitos respondentes para os dois grupos de cantores. Os cantores eruditos apresentaram maior percepção de sintomas vocais quando comparados aos populares para os escores total e emocional da ESV. Cantores populares e eruditos não apresentaram diferenças no conhecimento em saúde e higiene vocal, ambos os grupos obtiveram valores acima da nota de corte de normalidade do QSHV. Não houve correlação entre o conhecimento em saúde e higiene vocal e os sintomas vocais em cantores. Conclusão: Cantores eruditos são mais afetados por alterações vocais, principalmente as mulheres. Os cantores obtiveram um bom grau de conhecimento em higiene vocal, não diferindo em função dos estilos. A percepção de alteração vocal em cantores populares e eruditos parece não ter relação com o grau de conhecimento de saúde e higiene vocal.

Abstract: The objective of this work was to detect the inclusion of animal meal in Japanese quail (Coturnix coturnix japonica) diets, by analyzing eggs and their fractions (albumen and yolk) through the technique of carbon (13C/12C) and nitrogen (15N/14N) stable isotopes. Four hundred and thirty-two Japanese quails, 45-day-old females, were distributed in a completely randomized experimental design, in eight treatments: T1, strictly vegetable diet (VEG), with corn (Zea mays) and soybean (Glycine max) meal; T2, bovine meat and bone meal (BM); T3, poultry viscera meal (OM); T4, feather meal (FM); T5, BM+OM; T6, BM+FM; T7, OM+FM; and T8, BM+OM+FM. Sixteen eggs were randomly collected from each treatment - eight for whole egg analysis and eight for separate yolk and albumen analyses. To determine the turnover rate, the exponential isotope dilution model was used. The application of C and N stable isotopes allows identifying the use of animal meal in coded diets through the analysis of whole eggs and their fractions, which suggests that this technique is a promising tool for the traceability and certification of products of animal origin.

Authors: Napoli Pastore Marina Di
Published: July 2020

O ano de 2020 tem sido marcado por um cenário mundial em que a pandemia do Covid-19 e suas consequências trouxeram diversas questões sociais à tona, envolvendo a desigualdade social, a invisibilidade e o silenciamento de parcela significativa da população, tal como a amplitude de suas potências, principalmente no que tange a vida das crianças. O diálogo sobre a pluralidade das infâncias e das crianças, bem como das vulnerabilidades e modos de agir frente à Covid-19, tem permeado diversas discussões em disciplinas diversas, nas quais a terapia ocupacional também tem se inteirado, ainda que de maneira inicial, mas com pouca discussão em torna das crianças. Neste sentido e a partir desta constatação, este artigo apresenta uma discussão sobre o lugar das crianças no cenário da pandemia, a partir de reflexões teóricas que trazem para o cerne do debate questões relacionadas à invisibilidade das crianças e seus contextos que, com a situação atual, tornou-se mais evidente. Este texto pretende favorecer um espaço de construção de diálogo e de indagações sobre as ações dos terapeutas ocupacionais frente às infâncias e crianças, ancorado na pandemia do Covid-19, possibilitando a construção de práticas e ações contextualizadas e transformadoras.

In the present investigation, TiO2 nanostructures were synthesised via a simple sol-gel technique and characterised with X-ray diffraction (XRD), scanning electron microscopy with energy-dispersive X-ray analysis (SEM-EDX), high-resolution transmission electron microscopy (HR-TEM) and ultraviolet-visible (UV-vis) spectroscopy. The temperature and concentration dependence of thermal conductivity enhancement (TCE) and ultrasonic velocity have been explored in ethylene glycol-based TiO2 nanofluids. The obtained results showed 24% enhancement in thermal conductivity at higher temperature (80°C) of the base fluid ethylene glycol by adding 1.0 wt% of TiO2 nanoparticles. The behaviour of TCE and ultrasonic velocity with temperature in prepared nanofluids has been explained with the help of existing phenomena. The increase in ultrasonic velocity in ethylene glycol with TiO2 nanoparticles shows that a strong cohesive interaction force arises among the nanoparticles and base fluid. These results divulge that TiO2 nanoparticles can be considered for applications in next-generation heat transfer in nanofluids.
Contradictions in the Treatment of Roma and Sinti During the Holocaust
Authors: Price Katherine
Published: July 2020

In this article, I argue that the Nazi treatment of Roma and Sinti Gypsies was distinct from their treatment of other victim groups by virtue of its inconsistency. There was never a very clear articulation of the ideological position of the Nazis regarding the Gypsies, and the guidelines that werein place were applied inconsistently. A wide variety of exemptions theoretically protected Gypsies from arrest and deportation. For example, as distinct from the Nazi beliefs about Jews, so-called racially pure Gypsies were sometimes considered more valuable and were protected. These rules, however, were never consistently followed. The extent to which Gypsies were persecuted by the Nazis was often determined more by the attitudes and personal beliefs of lower level administrators, combined with the perceived demands of the local situation, than by an intentional Nazi mandate.
