Inclusion regions and bounds for the eigenvalues of matrices with a known eigenpair
Authors: Marsli Rachid , Hall Frank J.
Published: November 2020

Let (λ, v) be a known real eigenpair of an n×n real matrix A. In this paper it is shown how to locate the other eigenvalues of A in terms of the components of v. The obtained region is a union of Gershgorin discs of the second type recently introduced by the authors in a previous paper. Two cases are considered depending on whether or not some of the components of v are equal to zero. Upper bounds are obtained, in two different ways, for the largest eigenvalue in absolute value of A other than. Detailed examples are provided. Although nonnegative irreducible matrices are somewhat emphasized, the main results in this paper are valid for any n × n real matrix with n≥3.
The technical term‘amphibolon’in Pollux’sOnomasticon
Authors: Chronopoulos Stylianos
Published: November 2020

Pollux uses the technical term‘amphibolon’in different contexts and with relatively different functions. This paper documents in detail these functions, categorizes them in 5 different categories (marking of polysemous lexemes; marking of polysemous lexemes in specific passages; highlighting dubious readings in specific passages; marking of a doubtful categorization of a thing; marking lexemes which are dubious regarding their canonicity) and discusses their relation with lexicographic features and intentions of theOnomasticon. It contributes contributes, thus, to the disambiguation of the term in theOnomasticonand adds some insights about its uses in the ancient Greek grammatical and lexicogrpahical tradition.
Insta-Research zum #westweg im Schwarzwald – wie digital repräsentierte Wandererfahrungen auf Instagram mittels quantitativer und qualitativer Methoden untersucht werden können
Authors: Winsky Nora , Zimmermann Gisela
Published: November 2020

Der Westweg im Schwarzwald ist Deutschlands ältester Fernwanderweg und erfreut sich bei in- und ausländischen Gästen großer Beliebtheit. Diese dokumentieren nicht nur die physische Anstrengung des Wanderns, sondern vielfach auch die landschaftliche Ästhetik des Schwarzwaldes u. a. mithilfe von Instagram-Posts. Solche Posts sind Ausdruck für die untrennbare Verflechtung von neuen Medien und Reiseerfahrungen im digitalen Zeitalter. Mit einem innovativen Analyseschema, das einen Zugang mittels quantitativer und qualitativer Methoden umfasst, wird exemplarisch für den #westweg aufgezeigt, wie digital repräsentierte Wandererfahrungen wissenschaftlich erfasst und analysiert werden können.

Mittels der quantitativen Analyse lassen sich die Beiträge nach den meistgenutzten Hashtags (u. a. #schwarzwald, #blackforest, #wandern) und Emoticons (u. a. Tanne, Smileys) filtern, die das Datenmaterial thematisch strukturieren und klassifizieren. Eine qualitative Einzelbildanalyse schließt an und identifiziert aktuelle Bildpraktiken und Bedeutungskonstitutionen auf Instagram zum #westweg. Die Analyseverfahren stellen die Inszenierung der Landschaft als idyllisch einerseits sowie die Naturerfahrung im Spannungsfeld von Anstrengung und Genuss andererseits heraus. Bildmotive, wie sie aus der Romantik bekannt sind, haben bis heute Bestand und werden auf der sozialen Fotoplattform in ein neues Licht gerückt.
Companions of Nabonidus
Authors: Sandowicz Małgorzata
Published: November 2020

In his seminal 1989 study, Paul-Alain Beaulieu argued that Nabonidus was brought to power by a conspiracy orchestrated by Belshazzar and servants of Neriglissar and Lâbâši-Marduk, the usurper’s predecessors on the throne. This paper offers a prosopographic investigation into Nabonidus’s social network and reveals that, at the outset of his reign, the new king’s entourage comprised other associates of Neriglissar and other potential conspirators.
Krisenzeit – Zeit für einen utopiestarken Religionsunterricht?
Authors: Schlag Thomas
Published: November 2020

Angesichts der durch die Corona-Krise des Jahres 2020 ausgelösten Disruptionen stellt sich für die religiöse Bildung in Schule und Kirche die Frage des theologisch und pädagogisch verantworteten, lebensdienlichen Umgangs mit diesen Krisenerfahrungen und damit nach den Folgerungen für die konkrete Bildungspraxis. Dabei sind von Beginn an fünf Aspekte, die die aktuelle Krise in besonderer Weise ausmachen, für alle Bildungsüberlegungen zu berücksichtigen. Diese werden im Folgenden aufgezeigt und zugleich mit zentralen Leitfragen für die religionspädagogische Klärung und in der Zielrichtung des Plädoyers für einen utopiestarken Religionsunterricht verbunden.
L’opposition moral(e) / éthique : une approche linguistique
Authors: Martin Robert
Published: November 2020

The Role of Location-Context Binding in Nonspatial Visual Working Memory
Authors: Cai Ying , Fulvio Jacqueline M. , Yu Qing , Sheldon Andrew D. , Postle Bradley R.
Published: November 2020

Successful retrieval of an item from visual working memory (VWM) often requires an associated representation of the trial-unique context in which that item was presented. In experiment 1, fMRI of 16 male and female humans replicated a previous dissociation of the effects of manipulating memory load in comparison to the effects of manipulating context binding, by comparing VWM for one oriented line versus for three lines individuated by their location versus for three “heterogeneous” items drawn from different categories (orientation, color, and luminance): delay-period fMRI signal in frontal cortex and intraparietal sulcus (IPS) was sensitive to stimulus homogeneity rather than to memory load per se. Additionally, inspection of behavioral performance revealed a broad range of individual differences in the probability of responses to nontargets (also known as “swap errors”), and apost hoccomparison of high swap-error versus low swap-error groups generated several intriguing results: at recall, high swap-error subjects were seen to represent both the orientation and the location of the probed item less strongly, and with less differentiation from nonprobed items, and delay-period signal in IPS predicted behavioral and neural correlates of context binding at recall. In experiment 2, which was a preregistered replication, the 27 male and female humans were grouped into low and high swap-error groups by median split, and the results were broadly consistent with experiment 1. These results present a neural correlate of swap errors, and suggest that delay-period activity of the IPS may be more important for the operation of context binding than for representation per se of stimulus identity.
Egypt’s Old Affliction of Aloof Rulers
Authors: Fahmy Khaled
Published: November 2020

Although official data suggest that Egypt avoided the worst of the COVID-19 pandemic, doctors have warned that the reality is far more grim. Their attempts to speak out have been met with harsh repression. A glance back at Egyptian history from the origins of the modern nation in the early nineteenth century reveals a consistent disregard for citizens’ health, apart from their usefulness as military conscripts.
Análisis de la relación entre el resultado de lectura crítica en las pruebas Saber 11, el promedio académico y el desempeño en tareas de atención y memoria en estudiantes universitarios
Authors: Amaya Díaz Laura Patricia , Rivera Carvajal Raquel , Acosta Salazar Hadder Uriel
Published: November 2020

Se analizó la relación entre el resultado de lectura crítica en las pruebas Saber 11, el rendimiento académico y el desempeño en tareas de atención y memoria en 55 estudiantes universitarios (edad media=20 años, D.T.=2.51) a través de la prueba Memometric, la subprueba de retención de dígitos de Wechsler y el test de cancelación de la A. Como resultado, se encontró que el rendimiento en el módulo de lectura crítica y el desempeño académico no se relacionan únicamente con procesos psicológicos básicos como la atención selectiva y la memoria de trabajo. Adicionalmente, las correlaciones entre las variables estudiadas fueron bajas (con puntuaciones entre r = .004 y r = .42; p < .05), a excepción de dos, que pueden ser consideradas como moderadas: inverso memometric y promedio académico con un r ,50 p < .05; y directo memometric e inverso memometric, con un r = ,67, p < .05. Con el análisis posterior del modelo de regresión se observó que el desempeño en la prueba de lectura crítica Saber 11 fue significativo para la predicción del rendimiento académico. En conclusión, solo fueron corroboradas dos de las relaciones planteadas. Se sugiere para futuras investigaciones incluir variables relacionadas con los recursos afectivos del estudiante y los ambientes de aprendizaje.

Parameters of the envelope of the magnetoelastic acoustic emission signal are proposed to be used as informative ones. To study the properties of the envelope of the signal, experimental studies on steel St.3 and nickel specimens are investigated. The signal envelopes for a number of values of the amplitude of the remagnetizing field induction are estimated by several imple¬mentations. It is shown that the shape and duration of the envelope of the magnetoelastic acoustic emission signal depends on the amplitude of the remagnetization field induction, which requires ensuring their stability when using the parameters of the envelope as informative by diagnosing ferromagnetic objects. To test the new informative parameter, uniaxial tensile forces were applied to nickel and steel specimens of the same size and shape (for nickel the stresses were changed from 0 to 110 MPa, for steel to 280 MPa), the specimens were remagnetized with the outside field and the magnetoelastic acoustic emission signals were registered. Estimates signals of the envelope for different values of the applied load are found. The dependences of duration of the magnetoelastic acoustic emission signals on the magnitude of the applied stresses, which can be used as calibration curves for diagnosing residual stresses in ferromagnetic objects of long-term operation, are constructed.

The correlation and spectral properties of a multicomponent narrowband periodical non-stationary random signal (PNRS) and its Hilbert transformation are considered. It is shown that multicomponent narrowband PNRS differ from the monocomponent signal. This difference is caused by correlation of the quadratures for the different carrier harmonics. Such features of the analytic signal must be taken into account when we use the Hilbert transform for the analysis of real time series.
Organizational identity: components and construction
Authors: Gonzales-Miranda Diego René
Published: November 2020

The objective of this research was to understand the identity construction process of the middle managers (MMs) of a Colombian multilatina. From the research question, i.e., what are the components involved in the identity construction process of MMs?, it was established that MMs are those individuals whose level in the organization is below top managers and above first-level supervisors. The theoretical framework used was organizational identity (OI). To this end, literature review focused on the discussion of research works whose epistemological basis considered OI as a process, not as an invariant or static element. The case study used a qualitative approach. Identity construction processes are made up of three categories: recognition, transcendence and security. The research was conducted under the case study method and targeted a relatively new organi­zation that is in an unfinished and immature process of adopting a specific OI. The components explain the process and make it possible to elucidate a new way of approaching it at the manage­ment level; at the same time, due to their clarity and understandability, they can be used for other studies, as well as for consultancies. Finally, the integration of concepts from the social sciences for conceptualization and analysis nourishes the dialog with the administrative field.

The Association between Maternal Serum Vitamin D Levels and Gestational Diabetes Mellitus among Filipino Patients: A Cross-Sectional Study
Authors:   St. Luke's Medical Center, Quezon City, Philippines, Cabrera Carmen Carina , Dampil Oliver Allan , Ong-Lopez Albert Macaire
Published: November 2020

Objectives: To determine the association between low maternal serum vitamin D and gestational diabetes mellitus (GDM) among Filipino women in St. Luke’s Medical Center – Quezon City. Methodology: A cross-sectional study involving pregnant women at outpatient clinics in a tertiary hospital in the Philippines. Simultaneous testing for fasting blood sugar, 75g oral glucose tolerance test and serum vitamin D was done. Participants were classified as GDM versus non-GDM, and normal versus low serum vitamin D. Univariate and multivariate statistics were done to determine relationship between vitamin D and GDM. Results: Of 211 included women, 198 (93.8%) had low vitamin D levels, and 56 (26.5%) had GDM. Vitamin D was significantly higher in the GDM group (21.0±8.1 vs 18.8±5.3 ng/mL, p=0.0189). The proportion of women with low vitamin D levels was significantly higher among those without GDM (96.1% vs 87.5%, OR=0.28, p=0.029]. After adjusting for age, parity, history of GDM and pre-pregnancy BMI, no significant association was observed (adjusted OR=0.66, p=0.522). No correlation was seen between vitamin D and FBS (r=0.28, p=0.095), 1-hour post-75 g OGTT (r=0.26, p=0.643), and 2-hour post-75 g OGTT (r=0.28, p=0.113). Conclusion: There was an association found between maternal serum vitamin D level and GDM in the univariate analysis, but none was evident after adjusting for possible confounders. The unanticipated high prevalence of low vitamin D levels among pregnant Filipinos needs to be verified in future studies.

Objective. To determine the efficacy of rTMS in decreasing body mass index (BMI) versus sham stimulation among obese Filipino patients. Methodology. This was a single-center, randomized, sham-controlled, single-blind, parallel group trial. Participants were 15-65 years old with BMI ≥30 kg/m2 and weight stable for 6 weeks. Participants were randomized to receive real rTMS or sham stimulation. Each underwent 4 sessions of stimulation over 2 weeks. Anthropometrics, total caloric intake (TCI), and VAS score for appetite were taken at baseline, 2, 4, 6, and 12 weeks. Results. A total of 31 patients were randomized with 15 to the treatment and 14 to sham stimulation completing treatment, with 2 lost to follow-up. A significant decrease in BMI was noted after 4 weeks from the start of rTMS in the treatment group, (0.6±0.6, p-value=0.001), with weight change of -1.3±1.3 kg (p-value=0.009), but was no longer observed at 6 weeks onwards. No severe adverse effects were noted. Conclusion. rTMS to the DLPFC effectively decreased BMI (0.6±0.6) and weight (-1.3±1.3 kg) from baseline to 4 weeks. At 6-12 weeks after rTMS however, there was no longer a significant difference, indicating that 4 sessions of rTMS may not be enough to produce a prolonged effect on weight loss.
Triple Synchronous Tumors Presenting as Right Nasolabial Basal Cell Carcinoma, Papillary Thyroid Carcinoma and Prolactinoma: A Rare Case Report
Authors:   Southern Philippines Medical Center, Davao City, Te Mateo , Lumanlan-Mosqueda Donnah Bless , Demegillo KennyJun
Published: November 2020

Multiple primary tumors are rare, with a published meta-analysis that shows the frequency of second primary tumor at 3-5%, and a third tumor at 0.5%. A 57-year-old female sought consultation due to a persistently bleeding right nasolabial mass. On further history and examination, she also presented with a right anterior neck mass, repeated abortions, secondary amenorrhea, and loss of libido years prior. Serum prolactin was significantly elevated and an incidental finding of a pituitary mass on head and neck CT scan was appreciated. Metastasis and syndromic familial disorder were ruled out. Bromocriptine was given and she underwent total thyroidectomy and wide excision of the right nasolabial mass which turned out to be papillary thyroid carcinoma (PTC) and basal cell carcinoma (BCC) respectively on histopathologic report. On follow up, repeat serum prolactin decreased to normal levels. After extensive literature review, this is the first documented case of triple synchronous tumors with a combination of BCC of the right nasolabial area, PTC and prolactinoma in local, national and international studies. With comprehensive work up and literature search, the diagnosis was established and ultimately the patient benefited from a multidisciplinary management.
Performatività e improvvisazione: l’artista Teresa Bandettini Landucci
Authors:   Universität Salzburg, Winter Susanne
Published: November 2020

Teresa Bandettini Landucci (1763-1837) was a dancer, poet, and above all amongst the most acclaimed composers of extemporaneous verse in the late 18th century. Yet her legacy is all but forgotten, her name virtually unmentioned in histories of literature. Such an omission is a result of the general dismissal of female writing in literary history; but, in the case of Bandettini, it is all the more pronounced because she was an improviser. The aim of this study is to show that, firstly, in the 18th century, the profession of improvisation was one of the few cultural fields in which women could attain celebrity; and secondly, that the Western emphasis on the written word over orality, on printed documents over ephemeral performances, has meant that improvisation as a performative art has received little recognition or cultural legitimacy. The art of improvisation experienced a golden age in the second half of the 18th century. This depended upon an expression of enthusiasm within an impromptu performance, characterised by physical presence, the staging of the self, and the involvement of the public. The immediacy of the performance and the authenticity of the artist were decisive elements of this type of performance, though they were rarely recognised within a culture of literacy. Moreover, the transcription and publication of improvised poems could never communicate the nature of these performances and their cultural impact, in part because the oral nature of these texts was considered to be subordinate to meditated poetry. The marginalisation of Bandettini in literary history can therefore be ascribed to the dismissal of categories such as performance, orality, and ephemerality.
Alla ricerca di un capolavoro. Il teatro a la traduzione nelle lettere inedite di Sibilla Aleramo a Emilia Szenwicowa
Authors:   Uniwersytet Marii Curie-Skłodowskiej w Lublinie, Kłos Anita
Published: November 2020

Sibilla Aleramo (1876-1960) and Emilia Szenwicowa (1889-1972), Polish journalist and translator, met in 1927: the Italian writer hoped that Szenwicowa would translate her novel Amo dunque sono into Polish. A year later, Aleramo spent a few weeks on vacation in Positano, in the villa of the Szenwic family, where she often returned until the outbreak of World War II. In 1931, thanks to Szenwicowa’s mediation, Aleramo undertook the translation of Dom kobiet, a theatrical piece by Zofia Nałkowska, into French and literal Italian, using mediatory versions. A collection of Aleramo’s letters has recently been found in the family archive of the Polish journalist’s heirs. The letters, published for the first time in the present paper in fragments, testify to the profound friendship that united the two intellectuals, and document, amongst other things, their various collaborative projects concerning the translation of theatre plays from Polish to Italian. The aim of the paper is to analyse the moments of correspondence between Aleramo and Szenwicowa that refer to the theatre.
Quo vadis all’italiana: investigazione stilometrica sulle tra-duzioni milanesi del bestseller di Henryk Sienkiewicz
Authors:   Uniwersytet Wrocławski, Biernacka-Licznar Katarzyna , Rybicki Jan ,   Uniwersytet Jagielloński w Krakowie
Published: November 2020

Henryk Sienkiewicz’s novel Quo Vadis made its way into Italy at the end of the 19th century through the efforts of Neapolitan translator Federigo Verdinois. The first part of this paper outlines the history of the popularity of Quo Vadis by focusing on the operations of Milanese publishers that made the Polish novel part of their offer in a variety of ways (as translations, adaptations, reworkings, plagiarisms, etc.). Bibliometric methods are used to establish why so many publishing houses decided to publish Henryk Sienkiewicz’s Roman romance. The analysis of the bibliometric data of the published translations helped assess and describe the extent and the character of the popularity that the novel garnered among Milanese publishers. The second part of the paper relates the findings of a multi-method quantitative study of the same material. The number of word tokens was compared between the original and the translations. The lexical richness across the texts under study was compared by means of the moving average type-token ratio (MATTR). Sentence lengths were also compared, as was sentence length distribution as time series. Two different programmes (WCopyFind and Tracer) yielded very similar results on the degree of the similarity of five-word phrases in pairs of translations, which was determined in network analysis.

Published: November 2020

ABSTRACT Objective: to evaluate esophageal dysmotility (ED) and the extent of Barrett’s esophagus (BE) before and after laparoscopic Nissen fundoplication (LNF) in patients previously diagnosed with BE and ED. Methods: twenty-two patients with BE diagnosed by upper gastrointestinal (GI) endoscopy with biopsies and ED diagnosed by conventional esophageal manometry (CEM) were submitted to a LNF, and followed up with clinical evaluations, upper GI endoscopy with biopsies and CEM, for a minimum of 12 months after the surgical procedure. Results : sixteen patients were male (72.7%) and six were females (27.3%). The mean age was 55.14 (± 15.52) years old. and the mean postoperative follow-up was 26.2 months. The upper GI endoscopy showed that the mean length of BE was 4.09 cm preoperatively and 3.91cm postoperatively (p=0.042). The evaluation of esophageal dysmotility through conventional manometry showed that: the preoperative median of the lower esophageal sphincter resting pressure (LESRP) was 9.15 mmHg and 13.2 mmHg postoperatively (p=0.006). The preoperative median of the esophageal contraction amplitude was 47.85 mmHg, and 57.50 mmHg postoperatively (p=0.408). Preoperative evaluation of esophageal peristalsis showed that 13.6% of the sample presented diffuse esophageal spasm and 9.1% ineffective esophageal motility. In the postoperative, 4.5% of patients had diffuse esophageal spasm, 13.6% of aperistalsis and 22.7% of ineffective motor activity (p=0.133). Conclusion: LNF decreased the BE extension, increased the LES resting pressure, and increased the amplitude of the distal esophageal contraction; however, it was unable to improve ED.

Os dois jornais, porém, concordaram em preservar a agenda de reformas econômicas - o que evidencia a relevância dos editoriais para caracterizar as empresas jornalísticas como players do jogo político.
Abordajes de la violencia sexual en los juicios por delitos de lesa humanidad en Argentina
Authors: Alvarez Victoria
Published: November 2020

Resumen: Al igual que en otras dictaduras del Cono Sur, durante la última dictadura militar argentina (1976-1983), las mujeres detenidas fueron víctimas de distintas formas de violencia sexual. Recién en los últimos años, luego de la reapertura de los juicios por delitos de lesa humanidad y con una cantidad considerable de resistencias, se empezó a considerar la posibilidad de juzgar la violencia sexual como un delito diferenciado de los tormentos. En el presente trabajo nos proponemos dar cuenta de los principales debates jurídicos en torno a la posibilidad de juzgar estos delitos y argumentaremos en favor de la posibilidad de dicho juzgamiento.

Published: November 2020

Resumen A partir de leer el desarrollo de la protección de la infancia en clave feminista, este artículo busca historizar algunos debates contemporáneos que hacen de los derechos de la niñez uno de los instrumentos privilegiados para disputar las batallas por el control de los cuerpos y de la sexualidad de las mujeres en Argentina. Para ello, analizo la inscripción de la protección de la infancia en tres contextos (la emergencia del estado social argentino, los debates panamericanos sobre la protección de la niñez, y el contexto global de surgimiento de los derechos de la niñez), y a la luz de dos debates actuales, el embarazo forzado de niñas y la adopción por matrimonios igualitarios.

A Disciplina de Matemática na Escola Técnica Nacional (1942-1965)
Authors: Maciel Paulo Roberto Castor
Published: November 2020

Resumo O presente artigo tem como objetivo analisar a disciplina de Matemática na Escola Técnica Nacional (ETN) durante o período de 1942 a 1965. Como aporte teórico-metodológico, recorremos às ideias sobre história das disciplinas escolares de Chervel (1990), que indica a investigação de uma disciplina a partir de objetivos fixados e práticas pedagógicas realizadas e pelos itens constituintes (exposição de conteúdos, práticas de incitação e motivação, exercícios e aparelho docimológico). As fontes históricas utilizadas foram: legislação, programas, livros didáticos, apostilas e provas. A partir dos vestígios do passado, constatamos similaridades e diferenças com o Ensino Secundário. A disciplina se constituiu como uma representação de uma Matemática para a oficina, mas há muitas apropriações do Ensino Secundário.
Modos de enseñanza en los videotutoriales de matemáticas: equilibrio entre eficacia puntual y utilidad formativa
Authors: Soto Claudia Margarita Acuña , Liern Vicente
Published: November 2020

Resumo Presentamos una propuesta de análisis de videotutoriales de internet basado en los estilos cognitivos Holístico-analítico y Verbal-imaginativo. Para ello, se distinguen entre dos modos de enseñanza: la eficacia puntual (resolver un problema aquí y ahora) y la utilidad formativa (resolver un problema ahora y para problemáticas afines). La utilidad docente de un videotutorial puede depender de un equilibrio adecuado entre estos modos de enseñanza. Se trata de lograr resolver un problema ahora, pero con sustentos generales y a más largo plazo. La caracterización de los videotutoriales, en este sentido, podría ayudar a los profesores en la elección de videos, ya que según sus necesidades, las decisiones deberían ser diferentes. Sin embargo, no sólo debemos tener en cuenta el punto de vista del docente, sino el potencial incremento en la participación activa y autónoma del estudiante usando los videos adecuadamente elegidos. Para mostrar la aplicación de nuestro análisis, comparamos la producción de tres autores de habla hispana muy reconocidos, que ejercen gran influencia en la actualidad. A través del análisis de varios videos, que puede apoyarse en métodos cuantitativos, se exponen algunos efectos de los modos de enseñanza en la formación matemática.
Creencias y ansiedad hacia las matemáticas: un estudio comparativo entre maestros de Colombia y España
Authors: Fernández-Cézar Raquel , Hernández-Suárez César Augusto , Prada-Núñez Raúl , Ramírez-Leal Pastor
Published: November 2020

Resumen Los estudios comparativos son interesantes para encontrar similitudes o diferencias entre contextos educativos distintos. En el ámbito Latinoamericano existen algunos sobre las actitudes del profesorado de matemáticas, pero no son muy abundantes. Con este trabajo se pretende contribuir a este cuerpo de estudios comparando dos contextos insertados en los sistemas educativos de España y Colombia. El objetivo es analizar el conjunto de creencias y actitudes hacia las Matemáticas que reportan docentes de educación básica, con especial interés sobre la ansiedad. Se partió de la validación y contextualización del cuestionario sobre creencias y actitudes hacia las matemáticas. Se siguió la metodología de la Teoría Clásica de los Test. Se aplicó una prueba piloto para calibrar el instrumento; luego se administró a una muestra de 232 docentes en ambos países. Con los datos obtenidos se realizó un análisis comparativo para identificar semejanzas y diferencias entre los grupos. Los resultados evidencian similitudes epistemológicas en cuanto a los ítems relacionados con el euclidianismo. Sin embargo, en cuanto al cuasi-empirismo y el constructivismo se presentan marcadas diferencias por país. En relación con la ansiedad, las respuestas de los docentes divergen, dependiendo del contexto geográfico. Destaca el mayor nivel de ansiedad de los docentes españoles en comparación con los colombianos. Se probó que factores como el nivel de estudios y el tipo de contratación determina su nivel de ansiedad y su sistema de creencias. A futuro convendría comprobar si los niveles de ansiedad afectan, también, a la práctica docente durante la enseñanza de las matemáticas.

Published: November 2020

Resumo Este artigo apresenta uma reflexão teórica cujo foco é a defesa do uso concomitante das Teorias dos Três Mundos da Matemática e da Sociointeratividade como uma possibilidade para o alcance de melhores resultados em relação à aprendizagem de Matemática. A leitura analítica do referencial teórico trouxe elementos relativos à coerência epistemológica entre as teorias, elucidando justificativas para a sua associação, bem como sua utilização nas práticas educacionais. A dimensão da linguagem, o uso de símbolos e os momentos mentais do sujeito são enunciados como pontos convergentes, fundamentando a coerência teórica. A complementariedade entre ambas as teorias também é analisada, propondo-se, desse modo, um uso ampliado de cada uma das teorias.
INFÂNCIA E PATOLOGIZAÇÃO: CONTORNOS SOBRE A QUESTÃO DA NÃO APRENDIZAGEM
Authors: Barbosa Mariana de Barros , Leite César Donizetti Pereira
Published: November 2020

RESUMO Neste texto nos propomos a refletir acerca de alguns aspectos relacionados aos processos patologização/medicalização da infância, alinhados a uma perspectiva psicopedagogizante, cultural, social e médica criando algumas conexões desta temática com os conceitos de bipolítica, rostidade e das práticas de poder que operam na perspectiva de um efetivo controle sobre a vida e a existência humana. Ressaltamos como a medicalização tem sido a principal forma de tratamento das supostas patologias e como esta prática tende a individualizar os sujeitos em um sentido negativo atribuindo exclusivamente a estes problemas que têm origem em diversos contextos políticos, históricos e sociais.
Association between severe chronic kidney disease defined by cystatin-c and creatinine and clinical outcomes in an elderly population - an observational study

Published: November 2020

ABSTRACT Introduction: Estimated glomerular filtration rate (eGFR) based on serum cystatin-C (sCys) seems as accurate as when based on serum creatinine (sCr), but sCys seems a better predictor of adverse outcomes. We aimed to study whether sCys could be a reliable tool for the prediction of adverse outcomes in elderly patients with severe chronic kidney disease (CKD). Methods: A group of 348 elderly patients with non-end-stage CKD (stages 1-4, according to eGFR-EPI sCr and/or sCys), referred to our consultation unit during 2016, was retrospectively studied and divided into four exclusive categories: CKD_stage4_neither (eGFR-sCr≥30mL/min; eGFR-sCys≥30mL/min), CKD_stage4_sCr_only (eGFR-sCr<30mL/min), CKD_stage4_sCys_only (eGFR-sCys<30mL/min) and CKD_stage4_combined (eGFRsCr<30mL/min; eGFR-sCys<30mL/min). Baseline characteristics, predictors of death, and clinical events (cardiovascular events and admissions for cardiovascular, acute kidney injury or infectious events) were explored until December 2018. Results: A 77±7.4 year-old cohort, with a modified Charlson Comorbidty Index (mCCI) of 3 (IQR:1-4), was followed-up during 29 (IQR: 26-33) months. There were no significant differences between the characteristics of the stage 4 groups. Survival analysis was stratified by follow-up at 12 months, and in the first year, survival curves of CKD_stage4_sCys_only and CKD_stage4_combined groups were significantly lower than the other groups (p=0.028). Adjusting for age, sex, and mCCI, CKD_stage4_sCys_only, conversely to CKD_stage4_sCr_only, had higher rates of clinical events (p<0.05) than CKD_stage4_neither group. Conclusion: In elderly patients with discordant CKD staging, sCys-based eGFR seems to be a better predictor of adverse outcomes than sCr-based eGFR. Patients with stage 4 CKD defined by sCr alone seem to behave similar to those with less severe CKD.

Abstract The coronavirus (Sars-Cov-2) pandemic raised the need for social distance to reduce its spread. Chronic kidney disease patients on renal replacement therapy are especially susceptible to developing the most severe form of COVID-19, and, at the same time, require regular medical and multidisciplinary periodic follow-up. On an emergency basis, Brazil’s professional regulatory bodies authorized telehealth assistance, which made possible to migrate from face-to-face to distance appointments in health services across the country, when necessary. This article’s main objective is to describe the process of developing and implementing telehealth for monitoring renal transplant patients and patients on peritoneal dialysis during the COVID-19 pandemic.
La damntopofanía en el arte rupestre venezolano o la antinomia lógica campesina/patrimonio cultural
Authors: Páez Leonardo
Published: November 2020

Resumen A partir de datos acopiados mediante técnicas de investigación documental y de campo, y utilizando como unidades de análisis categorías conceptuales pretendidamente enmarcadas dentro de las teorías animistas, se presentan algunas premisas que intentan explicar las tramas de significación comunitaria sobre el arte rupestre en las regiones históricas venezolanas y su relación con la noción de patrimonio cultural. Se sugiere la posibilidad de que ciertas representaciones locales constituyan elementos antinómicos al concepto de patrimonio. A pesar de ello, se trataría de referentes que otorgan sentido al arte rupestre dentro del paisaje conceptualizado en el que se inserta, por tanto un elemento a considerar en su patrimonialización por, para, con y en las comunidades.
Do ‘largão’ da terra ‘voluta’ à estreiteza da terra vendida: reflexões sobre territórios e comunidades quilombolas no norte de Mato Grosso do Sul
Authors: Oliveira Jorge Eremites de , Pereira Levi Marques
Published: November 2020

Resumo Neste artigo, os autores analisam as transformações ocorridas nas formas de acesso à terra por diferentes segmentos da sociedade nacional no norte do estado brasileiro de Mato Grosso do Sul. A discussão é realizada em torno do caso da comunidade quilombola Família Bispo, localizada no município de Sonora, região historicamente vinculada a uma área fronteiriça entre os territórios dos povos indígenas Bororo e Kayapó. O caso analisado é emblemático porque abrange indígenas, quilombolas e migrantes de outros estados da federação, todos envolvidos por relações de alianças e disputas, as quais têm como foco principal a posse e a propriedade da terra. A transformação do espaço, com anuência e participação de agentes do Estado nacional, resultou, segundo a expressão de um interlocutor, na expropriação dos territórios indígenas e quilombolas, pois o ‘largão’ da terra ‘voluta’ [devoluta] foi transformado em terra vendida, propriedade privada, regularizada com contratos e escrituras cartoriais.
Por uma pedagogia do cuidado: reflexões e apontamentos com base na Educação Popular em Saúde
Authors: Nespoli Grasiele , Paro César Augusto , Lima Luanda de Oliveira , Silva Cassiana Rodrigues Alves
Published: November 2020

Trata-se de um ensaio que analisa como a filosofia de Paulo Freire, apropriada pelos autores da Educação Popular em Saúde (EPS), possibilita uma ressignificação do cuidado. Em diálogo com a literatura sobre o tema, partimos de uma reflexão sobre noções que fundamentam a ontologia freiriana, como a valorização dos saberes e culturas populares, o diálogo, o respeito e a amorosidade, para, em seguida, buscar nas produções sobre EPS a compreensão de cuidado, seus pressupostos e caminhos para enfrentar a hegemonia da biomedicina, concepção que situa o cuidado como um conjunto de procedimentos técnicos centrado na doença. A análise aponta o cuidado como um ato político que, por diferentes vias, deve estar comprometido com a construção do mundo, o que implica a construção de uma vida autêntica capaz de superar a opressão.
