Modelling the Time Allocation Effects of Basic Income
Authors: Palermo Kuss Ana Helena , Neumärker K. J. Bernhard
Published: November 2018

Most of the economic models on basic income account just for pecuniary forms of work, i. e. “time spent making money”, in employment. This restriction is a drawback of these analyses and of the standard economic labor supply model itself. If one wants to understand the potential effects of basic income on individual and social welfare, one should not restrict observation to the pecuniary uses of time. The objective of this contribution is to rethink the meaning of work usually applied in economic models, based on contributions of other social scientists. This reassessment is undertaken through the development of a microeconomic model, which discusses the effects of basic income on time use and interprets work not just as a source of income, but also of non-pecuniary benefits. Further, we disentangle the usual work-leisure dichotomy in two other ones (paid and unpaid time/unpaid work and leisure).
L’equilibrio dopo il movimento: percezione e conoscenza fra Democrito e i medici ippocratici
Authors: Sassi Maria Michela
Published: November 2018

This paper analyses chapter 58 of Theophrastus’ De sensibus, where Democritus’ account of phronein is famously presented. Democritus traces phronein to symmetria of the soul, that is conceived, in turn, as a state of thermic equilibrium, depending on his consideration of psyche as an aggregate of spherical and thin atoms flowing throughout the body and giving it life, movement, and perception. As a consequence, according to him, psychic states go hand in hand with changes in the body. In the following section of this paper, I offer additional evidence in favor of the controversial manuscript reading μετὰ τὴν κίνησιν. As a result, a consistent theory by Democritus can be reconstructed, according to which the balanced state of mobility and temperature of the psychic atoms concentrated in the head that generates a correct thinking necessarily follows the movement of sensible eidola throughout the body. In fact, a number of passages from Hippocratic writings attest that Democritus shared the key features of this explanation with the physiological and medical approach of the time.
Ipathedi Epicuro tra epistemologia ed etica
Authors: Verde Francesco
Published: November 2018

The focus of this paper is the analysis of the epistemological and practical role played bypathe/affections in Epicurus’ philosophy. Epicurus firstly considered the affections not as emotional/passional conditions, but as firm criteria of truth and more specifically as the third criterion of the canonic (i.e. the epistemological part of his philosophical system). In this article the critical reactions (in particular by the Peripatetic side: Aristocles of Messene) against the Epicurean position about the function of the affections will be investigated too. Finally, two parts of this paper are devoted to the Cyrenaic tripartition ofpathe(in all likelihood, a subject criticized by Epicurus) and to the probable doctrinal relationship between Epicurus’patheand Aristotle’sNicomachean EthicsBook 2.
The Stoics on the Mental Mechanism of Emotions: Is There a “Pathetic Syllogism”?
Authors: Gourinat Jean-Baptiste
Published: November 2018

The mechanism of emotions in Stoicism has been presented by Graver a decade ago as relying on a “pathetic syllogism” having as its premises a judgment about the goodness of a certain type of object and a judgment that it is proper to have a certain emotional response to that object. It is true that each emotion is an irrational impulse resulting not only from the opinion that something is good but also from the opinion that it is appropriate to have a certain type of emotional response to that object, as shown by Graver. However, the present paper intends to present an alternative to Graver’s view by reducing the mechanism of emotion to the mechanism of all impulses: each impulse is an assent given to the impression that it is befitting for me to accomplish certain actions, and what Cicero and Stobaeus describe is not the combination of two premises resulting in an emotion as a conclusion, but the idea that it is necessary to give one’s assent to the impulsive impression to produce an emotion. Likewise, in Seneca, it is in such a way that a preliminary form of impulse is transformed into an emotion. A universal judgment about an object being good or a reaction being appropriate is certainly involved in certain emotions, but not in all of them, since many emotions depend on a fresh impression that overwhelms the general rational judgments of someone due to one’s insufficient mental preparation and to the weakness of one’s mind. In those cases, an emotion may involve the impression that a behaviour or a feeling is appropriate without endorsing the idea that it is universally good or appropriate, since the mechanism of the emotion relies on the vividness of one particular impression even against one’s system of beliefs.
Seneca e la passione come esperienza fisica
Authors: Maso Stefano
Published: November 2018

If the ancient Stoics conceived passion as a judgment or the consequence of a judgment referring to external reality, it is correct to define their conception of the psyche as ‘monistic’; it is very different if we consider that passion is due to another faculty independent of reason. In this second case, a scenario opens up in which a realistic and ‘reified’ conception of passion emerges. With reference to this, in theLetter113 Seneca discusses the paradoxical thesis of the ancient Stoic scholars according to whom “the soul is an animal”, just as virtues and passions are. Through a series of close logical arguments, he shows the absurdities that can be reached in this way. By comparing this letter with theDe irawe can define the position of Seneca as a type of practical/operational imaginary dualism: the development of an original coherent form of monism. Not to give in to passion (for example to anger or libido) will not be just or not so much a psychological exercise of reason and will, but certainly a physical experience of resistance.
Thermal properties and morphology of polypropylene based on exfoliated graphite nanoplatelets/nanomagnesium oxide
Authors: Alateyah A. I.
Published: November 2018

Polypropylene/exfoliated graphite nanoplatelet (xGnP) composites reinforced with 2 wt.% nano-magnesia (n-MgO) have been successfully fabricated using an injection moulding machine. In the present study, the thermal properties and morphological structure of the composites were investigated. The XRD patterns of the composites showed xGnP and n-MgO peaks, and the intensity of the xGnP peaks increased with increased concentration in a polypropylene matrix. In addition, the SEM micrographs revealed a good dispersion of filler within the matrix. The nanocomposites showed better thermal stability than the pristine polymer. The improvement in onset temperature compared to virgin PP was found to be 3.6% for 100 wt.% PP, 4% for PP/1xGnP/2n-MgO, 5.5% for PP/2.5xGnP/2n-MgO, and 5.9% for PP/5xGnP/2n-MgO, PP/10xGnP/2n-MgO. In contrast, the crystallinity was reduced by the addition of fillers.

Authors: Han Benyong , Yin Fang , Liu Shiqing , Zhao Xingling , Liu Jing , Wang Changmei , Yang Hong , Zhang Wudi
Published: November 2018

Methyl laurate was synthesized from lauric acid and methanol using Brønsted acid ionic liquids as catalysts, by an esterification reaction. The efficiencies of four different catalysts, 1-methylimidazolium hydrogen sulfate ([Hmim]HSO4), 2-pyrrolidonium hydrogen sulfate ([Hnhp]HSO4), 1-(3-sulfonic acid) propyl-2-pyrrolidonium hydrogen sulfate ([C3SO3Hnhp]HSO4) and H2SO4 were compared. The effect of the methanol/lauric acid molar ratio, reaction temperature, reaction time, and catalyst dosage on the lauric acid conversion was investigated by single-factor experiments. On the basis of single-factor experiments, the esterification of lauric acid and methanol was optimized using response surface methodology (RSM) based on central composite design (CCD). The results showed that the most effective catalyst was the ionic liquid [C3SO3Hnhp]HSO4. The optimal conditions were as follows: [C3SO3Hnhp]HSO4 dosage of 10 % (based on the mass of lauric acid), methanol/lauric acid molar ratio of 9:1, reaction time of 1 h and reaction temperature of 70 °C. Under these conditions, the lauric acid conversion reached 95.33 %. The catalytic activity of [C3SO3Hnhp]HSO4 still remained high after 5 cycles.

Authors: Barmala Ehsann
Published: November 2018

Optical NAND gate is a universal gate which can be used for implementing different kinds of combinational circuits without using other gates. Due to significance of optical NAND gates in the optical communications, in this paper we proposed a novel structure for designing an all optical NAND gate based on photonic crystal structures. The proposed structure was designed using threshold switching mechanism which can be implemented using nonlinear ring resonators. In the proposed structure delay time is about 2.3 ps.

Published: November 2018

A super edge-magic total (SEMT) labeling of a graph ℘(V, E) is a one-one map ϒ from V(℘)∪E(℘) onto {1, 2,…,|V (℘)∪E(℘) |} such that ∃ a constant “a” satisfying ϒ(υ) + ϒ(υν) + ϒ(ν) = a, for each edge υν ∈E(℘), moreover all vertices must receive the smallest labels. The super edge-magic total (SEMT) strength, sm(℘), of a graph ℘ is the minimum of all magic constants a(ϒ), where the minimum runs over all the SEMT labelings of ℘. This minimum is defined only if the graph has at least one such SEMT labeling. Furthermore, the super edge-magic total (SEMT) deficiency for a graph ℘, signified as $\mu_{s}(\wp)$ is the least non-negative integer n so that ℘∪nK1 has a SEMT labeling or +∞ if such n does not exist. In this paper, we will formulate the results on SEMT labeling and deficiency of fork, H -tree and disjoint union of fork with star, bistar and path. Moreover, we will evaluate the SEMT strength for trees.
„Gespräche mit Dionysos“. Nietzsches Rätselspiele
Authors: Zittel Claus
Published: November 2018

“Conversations with Dionysus”. Nietzsche’s Playful Riddles. Nietzsche has written several short dialogues that are rarely studied. Based on the mysterious ‘conversations with Dionysus’, which also include the Dionysian Dithyramb „Ariadneʼs Lament“, the paper outlines their enigmatic structure and, on this basis, proposes an interpretive model for Nietzscheʼs labyrinthine texts.
Nietzsche’s Genealogy: A Textbook Parody
Authors: Inkpin Andrew
Published: November 2018

Given its apparently scholarly form, the Genealogy of Morals is often read as a succinct, relatively systematic, and canonical exposition of Nietzsche’s mature views on morality. This article argues, however, that the work was intended as a parody of a scholarly treatise and examines how this parody is best understood. It begins by surveying some evidence that supports reading the Genealogy as a ‘textbook’ presentation of Nietzsche’s views. It then develops an exegetic case for reading it as a work of parody, based on the third essay’s claims about the ‘self-cancellation’ of truth-directed discourse and how to oppose the ascetic ideal, along with the Genealogy’s internal organization and its place in Nietzsche’s oeuvre. Finally, it examines whether this parody is best interpreted philosophically as having the force of a strong parody that denies the possibility of truth-directed enquiry or that of a weak parody denying the intrinsic value of such enquiry. Although reading it as a strong parody perhaps makes it more radical and potentially appealing, I argue that the Genealogy is best read as a weak parody, because this is both more tenable and suffices for the claims Nietzsche himself makes about the work’s aims and character.
Nietzsche auslegen und kommentieren: Neue Interpretationen von Jenseits von Gut und Böse
Authors: Venturelli Aldo
Published: November 2018

Reading and commenting on Nietzsche. New interpretations of Beyond Good and Evil. Two recent volumes on Nietzsche’s text highlight its fundamental ambivalence. On the one hand, Beyond Good and Evil is marked by a dynamic openness for experiment, critique of dogmatism, and stylistic sophistication; on the other hand, the argument centers on themes, such as the opposition between slaves and nobles, exploitation and new forms of tyranny, decadence and will to power, harshness and cheerfulness. Following the two volumes under discussion, I examine how and whether these diametrically opposed aspects of Nietzsche’s text can be brought together in a way that also allows us to reassess other basic themes of Nietzsche’s thought. The latter include the oppositions between the unity and the plurality of the will to power, Nietzsche’s emphasis on the „free spirit“ and his search for a „higher type“, his critique of morality and the creation of new values, his commitment to Europe and authoritarianism.
Nietzsche’s Jewish Problem and Great Politics: The Continued Research Interest in his Political Thought
Authors: Knoll Manuel
Published: November 2018

After presenting an overview of the research on Nietzsche’s political thought, this article discusses Robert C. Holub’s book Nietzsche’s Jewish Problem (2016). While Holub talks about Nietzsche’s “eugenic calculations”, he does not mention his notion of a “great politics”, which aims at breeding superior humans. This notion is central for Hugo Drochon’s Nietzsche’s Great Politics (2016) and Gary Shapiro’s Nietzsche’s Earth. Great Events, Great Politics (2016), which are critically examined in the article. Shapiro’s “postmodern” interpretation of Nietzsche’s thought neglects Zarathustra’s crucial statement that “The Übermensch is the meaning of the earth”. Drochon uses Bernard Williams’s four criteria to define what a “coherent politics” is. Drochon’s arguments that Nietzsche is indeed a political thinker are persuasive. However, William’s criteria are not sufficient and need to be amended.

Published: November 2018

Estimates of the accuracy of clinical diagnosis of Parkinson’s disease (PD) range between 46% and 90%, the accuracy of diagnosis dependent on prolonged clinical observation and clinical response to levodopa. For this reason, we need reliable diagnostic biomarkers. The cardinal hallmark of PD is alpha-synuclein aggregation in the brain. Demonstrating pathological alpha-synuclein in live patients would be useful for identifying and monitoring PD patients. By autopsy studies and in vivo studies, the presence of alpha-synuclein has been demonstrated even outside the central nervous system and the gastro-enteric tract appears to be the most promising candidate tissue for biopsy-taking and the esophagus and salivary glands appear to be the area with the highest concentration of alpha-synuclein. The purpose of our study is to conduct a review to determine the utility of salivary gland biopsy for the histological diagnosis of PD. A computerized medline study was carried out through the use of pubmed: using the MeSH terms: ‘salivary gland biopsy for PD’, ‘PD and dysphagia’, ‘alpha-synuclein and salivary gland’. We found 9 articles about minor salivary glands and submandibular gland biopsy for diagnosis of PD. According to the results of this review, the submandibular gland biopsy is the test with the increased sensitivity and specificity compared to the biopsy of the minor salivary glands (sensitivity: 0.85 and 0.37 respectability and specificity: 0.96 and 0.94 respectively). New studies are necessary on a wider population to confirm these results.
Sprachenwahl im Tourismus: Italienisch
Authors: Moraldo Sandro M.
Published: November 2018

Tourism is the leading economy of the 21st century also for Italy. The language could also benefit from it, which statistically performs very well in many areas (on the world stage, on the internet, in foreign language learning, etc.). Unfortunately, the country’s tourist-economic importance does not correlate positively with its language value. Here, the Italian state is asked to do more with investment for the ‚visibility’ of the language in the tourism sector, e.g. with the opening of foreign ENIT headquarters.
Deutsch als plurizentrische Sprache und der Intertourismus zwischen den Zentren
Authors: Ammon Ulrich
Published: November 2018

After a short historical summary which shows how todayʼs political and geographic distribution of the German language has evolved, the concept of a pluricentric language is developed, with German being a case in point. Following this, the various - seven to ten - “centers” of the language are outlined, illustrated by maps, with their prominent linguistic, demographic and political features, as a possible approach toward a comprehensive typology of the centers of pluricentric languages. It is argued that each center's specific standard variants, which make it an (autonomous) center of the language, are fully valid and correct within their respective political realm. Furthermore, the Variantenwörterbuch des Deutschen is presented as the first comprehensive dictionary of a pluricentric language, containing the entire pluricentric variation of German. It is based on a newly conceived dictionary structure that provides easy access to any pluricentrally relevant linguistic feature. The central topic of the contribution is, however, the level of attraction of the various centers of a pluricentric language as tourist destinations for the inhabitants of the other centers of the same language. The study includes hints at possible methods of exploitation by the tourist industry - a topic also worthy of study for other pluricentric languages.
Differences in prosodic phrasing in marking syntax vs. focus: Data from Yanbian Korean
Authors: Jun Sun-Ah , Jiang Xiannu
Published: November 2018

In studying the effect of syntax and focus on prosodic phrasing, the main issue of investigation has been to explain and predict the location of a prosodic boundary, and not much attention has been given to the nature of prosodic phrasing. In this paper, we offer evidence from intonation patterns of utterances that prosodic phrasing can be formed differently phonologically and phonetically due to its function of marking syntactic structure vs. focus (prominence) in Yanbian Korean, a lexical pitch accent dialect of Korean spoken in the northeastern part of China, just above North Korea. We show that the location of a H tone in syntax-marking Accentual Phrase (AP) is determined by the type of syntactic head, noun or verb (a VP is marked by an AP-initial H while an NP is marked by an AP-final H), while prominence-marking accentual phrasing is cued by AP-initial H. The difference in prosodic phrasing due to its dual function in Yanbian Korean is compared with that of Seoul Korean, and a prediction is made on the possibility of finding such difference in other languages based on the prosodic typology proposed in (Jun, Sun-Ah. 2014b. Prosodic typology: by prominence type, word prosody, and macro-rhythm. In Sun-Ah Jun (ed.),Prosodic Typology II: The Phonology of Intonation and Phrasing. 520–539. Oxford: Oxford University Press).
Prophetic Polysemy and Polemic: The »Opened« Sword of Babylon in Ezekiel 21:33–34a
Authors: Miglio Adam E.
Published: November 2018

Ez 21,33–34a enthält Polyseme, die gegen Babylon polemisieren. Ausgehend von einer Übersicht mesopotamischer Praktiken für das Beleben und Beseelen von Waffen werden vergleichbares Vokabular und vergleichbare Bildsprache behandelt, die in Ez 21,33–34a verwendet werden, um ein quasi-hypostasiertes Schwert zu beschreiben. Dabei liegt das Augenmerk auf der Darstellung des Schwertes als »geöffnet« (פתוחה) und als von »Visionen« (חזות) und »Divination« (קסם) beeinflusst. Diese Beschreibungen erzeugen eine Polysemie, die einerseits die Vorstellung übermittelt, dass die Waffe für den Kampf vorbereitet und geschwungen wurde, und andererseits eine rituelle Praxis ins Gedächtnis rufen, die Waffen durch Divination für den Kampf bereitet.

Published: November 2018

Abstract The estimation of pineapple total leaf area by simple, fast and non-destructive methods allow inferences related to carbon fixation estimative, biotic and abiotic damages and correlating positively with yield. The objective was to estimate D leaf area and total leaf area and of ‘Pérola’ pineapple plants from biometric measurements. For this purpose, 125 slips were selected and standardized by weight for planting in pots. Nine months after planting in a greenhouse, the plants were harvested to evaluate the total leaf area of the plant, D leaf area and D leaf length and width using a portable leaf area meter. Pearson correlation analysis was made and it was observed significative positive and strong correlation among the studied variables. Then, regression models were adjusted. It was observed that the D leaf area of ‘Pérola’ pineapple can be estimated from the length and width of this same leaf and the total leaf area can be estimated from the D leaf area.
Practical approach to primary retroperitoneal masses in adults
Authors: Mota Micaela Maciel dos Santos , Bezerra Regis Otaviano França , Garcia Marcio Ricardo Taveira
Published: November 2018

Abstract Primary retroperitoneal masses constitute a heterogeneous group of uncommon lesions and represent a challenge due to overlapping imaging findings. Most are malignant lesions. Although they are more prevalent in adults, they can occur at any age. Such lesions are classified as primary when they do not originate from a specific retroperitoneal organ and are divided, according to the image findings, into two major groups: solid and cystic. The clinical findings are nonspecific and vary depending on the location of the lesion in relation to adjacent structures, as well as on its behavior. The main imaging methods used for staging and surgical planning, as well as for selecting the biopsy site and guiding the biopsy procedure, are computed tomography and magnetic resonance imaging. In most cases, the treatment is challenging, because of the size of the lesions, vascular involvement, or involvement of adjacent organs. In this article, we present a review of the retroperitoneal anatomy and a practical approach to the main imaging features to be evaluated, with a view to the differential diagnosis, which can guide the clinical management.
Paralelos entre a produção científica sobre saúde mental no Brasil e no campo da Saúde Mental Global: uma revisão integrativa

Published: November 2018

A Saúde Mental Global é um campo de ensino, pesquisa e prática, cuja prioridade é melhorar o acesso e assegurar a equidade no cuidado em saúde mental para todas as pessoas do mundo, propondo ações especialmente em países de média e baixa renda, como o Brasil. Diante desse panorama mundial e considerando o avanço local dos processos das reformas sanitária e psiquiátrica, torna-se importante investigar o estado atual da literatura brasileira e sua relação com a Saúde Mental Global, descrevendo como a produção nacional aborda assuntos enfatizados nesse campo. Assim, adotando abordagem qualitativa e perspectiva descritiva, foi realizada revisão integrativa da literatura do período de 2014-2015, por meio de pesquisa bibliográfica em português e inglês, utilizando os termos saúde mental e Brasil combinados a palavras-chave correspondentes aos principais tópicos discutidos por autores da Saúde Mental Global. Foram encontrados 88 artigos apreciados segundo sua autoria, periódicos e regiões de publicação, metodologia e de acordo com as categorias de análise e acesso; atenção primária; atenção psicossocial; determinantes sociais da saúde; direitos humanos; e equidade. Constatou-se haver na produção científica nacional um conjunto de estudos muito rico e diversificado com paralelos com a literatura da Saúde Mental Global, mas apresenta um baixo índice de sistematização. Esses achados revelam, portanto, que, apesar dos esforços para a geração de conhecimento local, existem barreiras que, possivelmente, comprometem a participação brasileira no debate internacional.

Resumen: Nuestro objetivo fue evaluar la relación entre los riesgos psicosociales y el burnout en un hospital español de media-larga estancia. Se realizó un estudio transversal en 2017, aplicando la versión española del MBI-HSS y el cuestionario F-Psico 3.1 del Instituto Nacional de Seguridad e Higiene en el Trabajo. Variables predictoras: características sociodemográficas, moduladoras y factores de riesgo psicosocial. Variables resultado: prevalencia de burnout y afectación de sus subescalas. La asociación entre variables se cuantificó con odds ratio. El cansancio emocional se asoció positivamente a los riesgos psicosociales vinculados a carga de trabajo, demandas psicológicas, participación/supervisión, desempeño de rol, relaciones/apoyo social y al consumo de ansiolíticos; fueron factores protectores los hijos, sentirse valorado por pacientes y compañeros, satisfacción laboral, optimismo y apoyo social. Las asociaciones halladas para la despersonalización fueron similares, pero más débiles. La baja realización personal se asoció positivamente a los riesgos psicosociales vinculados al tiempo trabajado, autonomía, variedad/contenido del trabajo, desempeño de rol y apoyo social; fue la subescala que mostró mayor número de variables sociodemográficas/moduladoras protectoras: estado civil, tener hijos, trabajar de noche, sentirse valorado por pacientes y familiares, ilusión por el trabajo, apoyo social, autoeficacia y optimismo. Según nuestros resultados, existe asociación entre los riesgos psicosociales y el burnout. Los individuos con mayor satisfacción laboral, autoeficacia y optimismo, afrontan mejor el estrés y son menos vulnerables a los riesgos psicosociales y al burnout
PORTUGAL E DÉCADA INTERNACIONAL DE AFRODESCENDENTES: A EDUCAÇÂO E OS TEMPOS DA VIOLÊNCIA COLONIAL
Authors: MARTINS BRUNO SENA , MOURA ADRIANO
Published: November 2018

RESUMO: Neste texto centramo-nos na realidade de Portugal, um dos atores centrais do infame comércio transatlântico de sujeitos escravizados e dos processos coloniais que definiram o mundo moderno. A partir da realidade portuguesa, sinalizamos a urgência de convocar a história colonial e seus legados de modo a confrontar as narrativas eurocêntricas que insistem em pensar a Europa a partir de visões benignas que a retratam ingenuamente como a casa dos direitos humanos e da democracia. A partir desta análise, avaliamos o potencial impacto, em Portugal, dos pressupostos que dão corpo à Década Internacional de Afrodescendentes para confrontar e denunciar um sistema educativo que, até hoje, tem no silenciamento das questões étnico-raciais o dispositivo central de reprodução das desigualdades raciais que marcam a sociedade como um todo.
NOTES ON EDUCATION FOR LIBERATION PEDAGOGY IN THE PAN-AFRICAN / BLACK INTELLECTUAL TRADITION
Authors: KING JOYCE
Published: November 2018

ABSTRACT: The article analyzes the North American context and strategies of the past and present Black American liberation. The author argues that despite the terror experienced by Black Americans during the process of slavery, in the struggle for civil rights, and in overcoming institutionalized racism, in their daily lives they experienced forms of psychic resilience nourished by the spirituality of the Black people, their thought informed by the Spirit. The collective courage of Black Americans and liberation pedagogy in the freedom struggle emerged out ofthis spiritually informed thought. All of this can be understood as an essentially liberating educational process. The Pan-African/Black intellectual tradition, understood as education for the pedagogy of liberation, offers a theoretical lens for the analysis and interpretation of this movement and struggle for freedom. This interpretive lens is absent from the curriculum and the professional preparation of educators and researchers in the United States. The author discussed the activism of Pan-African intellectual and Guyanese historian Walter Rodney (1942-1980) to synthesize this theoretical lens.
Criatividade e silêncio: encontros e desencontros entre os saberes tradicionais e o conhecimento científico em um curso de licenciatura indígena na Universidade Federal de Minas Gerais

Published: November 2018

Resumo: Neste trabalho analisamos os impasses decorrentes do encontro entre a cultura acadêmica e os saberes tradicionais em um Curso de Formação Intercultural para Educadores Indígenas da Faculdade de Educação da Universidade Federal de Minas Gerais. Em 2015 ocorreu a disciplina Relação com o Conhecimento, iniciada com a pergunta: "Como conhecemos as coisas?". Os discursos dos alunos sobre a natureza do conhecimento científico e do conhecimento tradicional, e os debates acerca do tema foram registrados em um diário de campo. Observamos tanto as formas com as quais os alunos explicaram a aproximação entre as duas maneiras de produzir e validar os conhecimentos em jogo, quanto percebemos momentos nos quais as vozes dos alunos foram silenciadas. Indagamos: o que provocou esse silêncio, uma vez que as aulas foram planejadas para serem dialógicas? Acreditamos que este trabalho traz contribuições para compreender as manifestações da interculturalidade em sala de aula nos cursos de formação para educadores indígenas.
Perspetiva Ciência, Tecnologia, Sociedade, Ambiente (CTSA) nos manuais escolares portugueses de Ciências Naturais do 6º ano de escolaridade

Published: November 2018

Resumo: Tal como a nível internacional, também em Portugal é grande a importância atribuída ao manual escolar, reconhecido como um dos recursos mais utilizado por professores e alunos. Por isso, o manual escolar converteu-se num objeto de estudo de diversas investigações no âmbito da Didática das Ciências. Uma das linhas de investigação diz respeito ao enfoque Ciência-Tecnologia-Sociedade-Ambiente (CTSA), considerado por muitos investigadores como uma das tendências atuais do ensino das ciências capaz de desenvolver a literacia científica dos alunos. Neste estudo, essencialmente qualitativo, construiu-se e aplicou-se um instrumento de análise para perceber se os manuais escolares portugueses de Ciências Naturais do 6.º ano exploram os conteúdos científicos relacionando-os com a tecnologia, a sociedade e o ambiente e se apresentam atividades de índole CTSA. Os resultados mostram que o enfoque CTSA está incorporado nos manuais analisados, mas de forma insuficiente e pouco explorada.

O estudo mostra que a visão integrada da Ciência, nas suas relações com a Tecnologia e a Sociedade, não era muito evidente nos manuais analisados, o que sugere a necessidade de os professores desenvolverem recursos didáticos com uma orientação CTS.

Resumo: Este texto traz um estudo exploratório sobre concepções de práticas docentes no ensino de Física de professores brasileiros e portugueses em efetiva regência de classe, em escolas públicas da educação básica em São Luís (Maranhão, Brasil) e em Coimbra (Portugal). As concepções foram formalizadas a partir de entrevistas com esses professores e analisadas segundo noções da Análise de Discurso de origem francesa, considerando as condições desses professores para identificar aspectos que, por terem as implicações desejadas para a aprendizagem de seus alunos, consideram importantes no momento do planejamento de suas aulas. Os resultados das análises destacam que os discursos dos professores portugueses e brasileiros manifestam tendências ao uso de referenciais metodológicos de ensino, sem restrições a possibilidades de diferentes abordagens pedagógicas.
A exigência conceitual na prática pedagógica de dois professores de Química que ensinam Química e Física
Authors: Souza Rosilene Ventura de , Santos Bruno Ferreira dos
Published: November 2018

Resumo: Este artigo apresenta uma pesquisa sobre os níveis de exigência conceitual da prática pedagógica de dois professores que lecionam Química e Física no Ensino Médio regular. Esses professores são formados em Química, mas também ensinam Física, uma prática comum nas escolas públicas brasileiras, relacionada com o déficit de professores de Ciências. A pesquisa foi realizada em duas escolas urbanas e envolveu a observação participante em sala de aula. Para a coleta de dados, utilizamos gravadores de áudio, diário de campo e entrevistas semiestruturadas. Nossa pesquisa está subordinada à teoria do discurso pedagógico de Basil Bernstein e à noção de exigência conceitual proposta por Ana Maria Morais e seus colaboradores. Nossos resultados apontam que as práticas pedagógicas de tais professores apresentam uma baixa exigência conceitual nas duas disciplinas que lecionam, sendo a formação inicial e o nível socioeconômico dos estudantes fatores que contribuem para essa característica.

Authors: Leite Fabiane de Andrade , Zanon Lenir Basso
Published: November 2018

Resumo: O estudo apresenta o desenvolvimento do coletivo de pensamento de professores da área de Ciências da Natureza em um programa de formação sob a perspectiva da investigação-ação emancipatória. Com o objetivo de analisar sentidos expressos pelos professores da área acerca do conceito de autonomia, a pesquisa delineou-se em um contexto formativo em que foram identificados dois estilos de pensamento: um conservador, que expressa um sentido de autonomia unilateral, e outro transformador, em que a autonomia é compreendida como um processo compartilhado. Os estilos de pensamento analisados constituem-se como importantes propulsores de movimentos formativos, alicerçados pela perspectiva dialética, a qual auxilia na qualificação dos processos de formação na área.
Reproductive ecology of Otocinclus vittatus (Regan, 1904) in the Pantanal floodplain, upper Paraguay River basin
Authors: Pereira M. J. , Súarez Y. R.
Published: November 2018

Abstract We studied the reproductive biology of Otocinclus vittatus in the southern Pantanal, Brazil. A total of 1066 fishes were analyzed (490 males, 488 females and 88 individuals of undetermined sex), sampled with a rectangular sieve and a seine net from February/2009 to January/2011. Variations in the sex ratio, seasonality in reproduction, fecundity, and size at first maturity were estimated. No variations were detected in the total sex ratio for the study period as a whole; although ratio has varied over time. The gonadosomatic index varied according to the river level, but not according to water temperature and rainfall. The mean fecundity was estimated at 84.1 oocytes, with a positive correlation with standard length. The size at first maturity (L50) estimated was 18.7 mm for females and 20.1 mm for males.

ABSTRACT The study aimed at verifying the patterns of bird community related to different land-use/land-cover. The study area was a Conservation Unit and its buffer area. We used the fixed-point method, visiting 80 points in five times, through one year. The points were plotted in lands agriculture (AGR) and planted forest (FP) and, in areas covered by native forest (NF). The diversity index (H'), abundance (IPA), richness (X2) and categories of species-trophic were calculated, as well as the difference between H' and X2 according to land-use/land-cover was verified by an ANOVA. We also evaluated the taxonomic and functional similarity of the bird community, based in IPA and bird presence/absence. There were significant differences for both X2 and H', comparing NF and FP; NF and AGRP and; AGRP and FP. Concerning the trophic categories, the significant differences were between NF and AGRP and; FP and AGRP, because AGRP is a homogeneous environment with less diversity of resources. Conversely, NF and FP presented similarities as a consequence of the heterogeneity of its structures that subsidize greater avifauna stability than other land-use/land-cover. We conclude that the bird diversity and richness is related to the complexity of the landscape structure.
Bioimpedância para avaliação da composição corporal: uma proposta didático-experimental para estudantes da área da saúde
Authors: Silva Marcelo Mariano da , Carvalho Raquel Santos Marques de , Freitas Marcelo Baptista de
Published: November 2018

Resumo Este artigo apresenta um experimento de bioimpedância voltado para estudantes da área da saúde e elaborado a partir de instrumentação tradicional encontrada em laboratórios de ensino de cursos de graduação. Essa proposta permite a introdução de grandezas físicas e conceitos básicos de circuitos elétricos através de um recorte interdisciplinar de medida de impedância do corpo humano e avaliação corporal. Sugere-se que o uso didático do experimento seja feito em etapas: (a) familiarização com o uso do osciloscópio e demais equipamentos, montagem do circuito equivalente para simular as medidas de bioimpedância e comparação das grandezas medidas e calculadas; (b) condução de medidas “in vivo” (c) cálculo das variáveis de interesse clínico a partir dos valores determinados experimentalmente de R e χc a 50 kHz e dos parâmetros antropométricos medidos. Concluiu-se que a operacionalização do experimento para fins didáticos é viável e seu emprego adequado para que os estudantes ascendam a uma melhor compreensão da medida de bioimpedância, tornando-se críticos em relação ao emprego de equipamentos comerciais na prática clínica. A exposição prática e conceitual usada reforça a importância de se re-examinar o propósito do conhecimento tradicional disciplinar na solução de problemas da área da saúde.
Rectal ulcer due to Kayexalate deposition – an unusual case

SUMMARY Sodium polystyrene sulfonate (PSP) or Kayexalate is a cation-exchange resin, widely used in the management of hyperkalaemia due to renal disease. A rare, yet potentially dangerous, adverse event related to sodium polystyrene sulfonate use is intestinal mucosal injury, especially in the colon. The injury to the gastrointestinal mucosa can range from mild and superficial to wall necrosis and bowel perforation. The mechanism that leads to mucosal damage remains unclear. However, it is believed that sorbitol, commonly given to counteract PSP’s tendency to cause constipation, may play an important role in the development of gastrointestinal injury. Other potential risk factors are uraemia or end-stage renal disease, hemodynamic instability, solid organ transplantation, postoperative status and concomitant opioid administration. The authors present a case of diarrhoea and haematochezia after the administration of PSP without sorbitol, in a patient with hyperkalaemia due to acute kidney injury, in the absence of other risk factors. A colonoscopy was performed and revealed a rectal ulcer which histological findings were suggestive of mucosal injury due to Kayexalate deposition. This case supports the concept that this widely used drug can itself, without sorbitol, cause injury to the gastrointestinal wall. Even though this is a rare adverse effect, the widespread use of this medication may put a large population at risk.

SUMMARY BACKGROUND AND PURPOSE Cerebral atherosclerosis is the main cause of lesions that contribute to vascular cognitive impairment and vascular dementia, followed by arteriosclerosis of small vessels and cerebral amyloid angiopathy. The purpose of this study was to compare the post-mortem radiological alterations of autopsied adults with the macroscopic alterations in the posterior region of these brains in order to establish a relationship between the two forms of analysis and to discuss the relevance of the prevention of vascular cognitive impairment in patients with encephalic atherosclerosis. MATERIALS AND METHODS Thirteen brains were analysed macroscopically to assess the degree of atherosclerosis of the basilar and the posterior cerebral arteries. The patients were autopsied in the Subject of General Pathology at General Hospital of Triângulo Mineiro Federal University in Uberaba, state of Minas Gerais, Brazil. The qualitative analysis of atherosclerosis was performed with classification into mild, moderate or severe. In the posterior region of the brains, width of sulcus and thickness of gyrus were measured by macroscopic analysis and by tomographic analysis. RESULTS AND CONCLUSIONS There was a decrease in calcarine sulcus width and an increase in medial temporal occipital gyrus thickness in patients with a higher degree of atherosclerosis, macroscopically and in tomography, respectively. Low oxygenation caused by atherosclerosis probably leads to an encephalic parenchyma inflammation that causes microglial cells hypertrophy provoking increase in the gyrus thickness and decrease in the sulcus width, as observed in the present study.
