Improvement of Power Quality Considering Voltage Stability in Grid Connected System by FACTS Devices
Authors: Patil Sarika D.
Published: January 2021

Recently the wind power generation has attracted special interest and many wind power stations are being in service in the world. In the wind turbine that mostly uses induction generators, tend to drain large amounts of Vars from the grid, potentially causing low voltage and may be voltage stability problems for the utility owner, especially in the case of large load variation on distribution feeder. Voltage-source converter based various FACTS devices have been used for flexible power flow control, secure loading and damping of power system oscillations. Some of those are used also to improve transient and dynamic stability of the wind power generation (WPGS).
Design of Control Secheme and Performance Improvement for Multilevel Dc Link Inverter Fed PMBLDC Motor Drive
Authors: Lanjewar Sagar. M. , Ramsha K.
Published: January 2021

PMBLDC motors are gaining a lot of popularity due to their high efficiency as the Permanent Magnets do not carry current which results in negligible copper losses as compared to asynchronous motors. This paper introduces a design for speed control of the PMBLDC motor using multilevel dc link inverter fed by a Boost Converter. The multilevel dc link inverter consist of five level voltage sources, which are controlled by switches. The motor can be driven at different speed level as per its load requirement by making use of five level MLDC Link Inverter. In case of traditional inverter which is only a one level inverter the speed cannot be controlled as per the load requirement. The MLDC link inverter provides the output voltage waveform in step shape form. Thus as the number of cells (n) increases output voltage touches the fundamental component. The input voltage is low, thus to increase the input voltage given to the MLDC link inverter the (Boost Converter) has been designed. The Boost Converter is placed in between (DBR)Diode Bridge Rectifier and (MLDCLI). Both the design and results of Single level inverter and Multilevel Dc Link Inverter are obtained and compared by using the MATLAB Software along with the use of Simulink and Simpower system Tools.

STRESS CONCENTRATION IN ISOTROPIC & ORTHOTROPIC COMPOSITE PLATES WITH CENTER CIRCULAR HOLE SUBJECTED TO TRANSVERSE STATIC LOADING
Authors: BANERJEE MOON , JAIN N. K. , SANYAL S.
Published: January 2021

The present study brings out the thorough analysis of isotropic and orthotropic fixed rectangular plate with center circular hole under transverse static loading condition. In this paper influence of stress concentration and deflection due to singularity for isotropic and orthotropic composite materials under different parametric conditions is obtained. The effect of thickness -to- width of plate (T/A) and diameter-to-width (D/A) ratio upon stress concentration factor (SCF) for different stresses were studied. An isotropic and one composite material were considered for analysis to determine the variation of SCF with elastic constants. Deflection in transverse direction were calculated and analyzed. Results are presented in graphical form and discussed. Three-dimensional finite element models were created using ANSYS software. Results showed that maximum stress appear near the vicinity of the hole at the upper and lower portions of the plate. The effect of material properties, (E1/E2) on SCF for stresses along x, y and z axis is established thorough this analysis.
Why Surface Treatment is must for Cold Drawing Mild Steel Tubes
Authors: Bainsla Sitaram
Published: January 2021

Cold Draw Welded (CDW) tubes find a wide array of applications in the automobile industry. Electric Resistance Welded (ERW) tubes are surface treated with certain chemicals to make them eligible for cold drawing. The surface treatment is a time consuming process. Efforts have been directed to eliminate it altogether or at least to reduce its cycle time. We have assiduously conducted certain trials to establish the nature and character of the surface treatment. With the knowledge thus generated, we have, in our capacity, attempted to analyze why surface treatment is sine qua non to cold draw.
Rapid Evidence Reviews for the Philippine COVID-19 Crisis
Authors: Dans Leonila F. , Cabaluna Ian Theodore G. , Bayona Howell Henrian G. , Dans Antonio L.
Published: January 2021

One of the consequences of the COVID-19 pandemic is an avalanche of information that is unprecedented in magnitude. In the past 2 months, healthcare providers, policy-makers and the general public have been overwhelmed by this phenomenon. Aside from usual news from TV, radio, newspapers and medical journals, people from all walks of life have had to process kilometric threads on viber, facebook and twitter, as well as hundreds of issuances from all government agencies - from the Office of the President down to the barangays. The information from these various sources are often inconsistent or conflicting, and are always rapidly evolving. New information emerges as outdated information is just beginning to circulate. To aggravate the situation, the chaos is taken advantage of by perpetrators of false information. Clearly, this “informageddon” has led to “information overload” – the inability to process facts because of volume or pace. The manifestation is the widespread panic we are witnessing from all sectors of society. The consequence is impaired decision making – by individuals, families, communities and policy makers. Ultimately, this may lead to a prolonged, uncontrolled pandemic characterized by avoidable deaths, disability, and huge social and economic costs. Even healthcare providers are affected. Because of fear, many feel pressured to do tests and give treatments for COVID-19, that are poorly tested for effectiveness and safety. To help manage the information for policy-makers, healthcare workers and the general public, a group of 70 clinical epidemiologists and health professionals gathered together from the Institute of Clinical Epidemiology, National Institutes of Health-UP Manila and the Asia-Pacific Center for Evidence Based Healthcare Inc. The group conducted voluntary rapid evidence reviews and referred to themselves as “The Rappers”. The reviews were graciously shared by Philippine Society of Microbiology and Infectious Diseases through their website (PSMID.org). The online version allowed regular and rapid updates as evidence accrued.
Use of Renin-Angiotensin System Antagonists in Patients with Hypertension and COVID-19 Infection: A Rapid Review and Meta-analysis
Authors: Flores-Genuino Rowena Natividad S. , Salud-Gnilo Charissa Mia , Osio-Salido Evelyn
Published: January 2021

KEY FINDINGSAmong patients with confirmed COVID-19 infection and hypertension, there is insufficient evidence that RASantagonists are associated with mortality or severe COVID-19 disease.• There is uncertainty with regards to the safe use of renin-angiotensin system (RAS) antagonists, such asangiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARB), for COVID-19 patientswith hypertension and other comorbidities (heart failure, chronic kidney disease) because of two possiblecontradictory mechanisms 1) upregulation of ACE2 receptors that may facilitate the virus entry into the lung.and 2) control of unabated angiotensin II levels reducing acute lung injury.• Based on very low-quality retrospective cohort studies, there is insufficient evidence that RAS antagonists areassociated with increased mortality (6 studies) or severe disease (10 studies) among patients with confirmedCOVID-19 infection and hypertension.• There are 36 ongoing studies (21 RCTs, 1 single-arm trial, 4 prospective cohorts, 4 retrospective cohorts, 4 casecontrol, and 2 cross-sectional) on this topic.• The European Society of Cardiology (ESC) Council on Hypertension, the International Society of Hypertension(ISH) and the joint statement by the American College of Cardiology (ACC), American Heart Association (AHA),and Heart Failure Society of America (HFSA) all caution against discontinuing RAS-related treatments inpatients with hypertension who become infected with COVID-19.

Authors: Mina-Cuaño Patricia Maria Gregoria , Villanueva Cary Amiel G. , Besa John Jefferson V. , Villafuerte Andrew Rufino M. , Villavicencio Jayson M. , Tang Vincent Anthony S. , Palileo-Villanueva Lia M.
Published: January 2021

KEY FINDINGS• Very low-quality evidence from a single retrospective study suggests that continuous renal replacementtherapy (CRRT) may reduce mortality among COVID-19 patients on invasive mechanical ventilation. Guidelinesrecommend CRRT for critically ill patients to minimize the risk of possible transmission, if this option is available.• Although uncommon, acute kidney injury (AKI) can occur in association with coronavirus disease 2019(COVID-19) and is associated with increased in-hospital mortality.• There are currently no published or ongoing clinical trials directly comparing dialysis modalities for acutekidney injury in COVID-19 patients.• In reducing the risk of transmission during dialysis: currently, there are no studies comparing one dialysismodality to another. The method of dialysis is still primarily determined by the clinical picture of the patient, theexpertise of the center, and the resources available. The American Society of Nephrology (ASN) recommendsCRRT over intermittent hemodialysis (IHD) for critically ill patients with COVID-19 to minimize patient contactwhen it is available, and resources allow. Otherwise, intermittent hemodialysis may be done provided that,infection control measures are strictly followed.• Several international and local guidelines recommend strict adherence to infection prevention and controlmeasures (e.g. hand hygiene, physical distancing, proper use of personal protective equipment (PPE), andcohorting of patients) who are undergoing dialysis.
Should Intravenous Immunoglobulin G (IVIg) be used in the treatment of COVID-19?
Authors: Gregorio Germana Emerita V. , Dans Leonila F.
Published: January 2021

KEY FINDINGS

There is conflicting evidence on the efficacy of intravenous immunoglobin G in the treatment of COVID-19

patients with severe disease.

Intravenous immunoglobulin G (IVIg) is a mixture of polyclonal immunoglobulin G (IgG3, IgG4) antibodies as well as variable amounts of proteins; IgA, IgE and IgM antibodies isolated and pooled from healthy donors. IgG is involved in viral neutralization, modulates anti-inflammatory cytokines and cytokine antagonists.

Immediate adverse effects of IVIg include flu-like syndrome, dermatologic side effects, arrhythmia, hypotension, and transfusion-related acute lung injury (TRALI). Delayed adverse effects can involve any organ which could be severe or even lethal

There was a retrospective study (Yun Xie 2020) and several case reports that described recovery of COVID positive patients with severe disease. However, a retrospective study showed that immunoglobulin G with steroids and antivirals did not improve COVID patients with acute respiratory distress syndrome (Liu Y 2020). Similarly, another study showed no significant difference in the 28- and 60-day mortality between the IVIg and non-IVIg groups but subgroup analyses reported that in those with critical COVID illness, 28 day mortality is decreased with IVIg (Shao Z).

There are eight registered clinical trials on the use of intravenous immunoglobulin G in COVID-19 patients.
La reapropiación política de los conceptos de religión política y religión civil por Paul E. Gottfried y Enzo Traverso para la crítica del presente. Contribución a un debate historiográfico
Authors: Sánchez Rodríguez Ángel
Published: January 2021

Este ensayo pretende contribuir al debate contemporáneo en torno a la legitimidad historiográfica de los conceptos de religión política y religión civil por medio de una vía inusual: analizando no el debate en sí sino la reapropiación política de los conceptos por parte de los historiadores Paul E. Gottfried y Enzo Traverso, quienes los aplican a la izquierda post-marxista y al culto a la memoria del holocausto respectivamente. La conclusión es que los conceptos de religión política y religión civil, cuando son usados de manera eminentemente polémica, dan pie a muchos de los defectos historiográficos que sus críticos les atribuyen. Sin embargo, actualizar su potencial político nos puede indicar mutaciones históricas significativas del mundo secularizado.

The Incomprehension of Terror as a Harbinger of “Post-Truth”?
Authors: Shor-Chudnovskaya Anna
Published: January 2021

This article is devoted to the attitude to truth as a part of political epistemology and of political culture in post-Soviet Russia. It considers the extent to which the Great Terror contributed to the development of a specific political epistemology, which is also largely characteristic of later periods of Soviet history and perhaps even of today. Of particular interest is the population’s perception of the terror as inaccessible or poorly accessible to logical understanding. As main sources, the article relies on two literary texts: Lydia Chukovskaya’s Sofia Petrovna and Veniamin Kaverin’s The Open Book. Despite all the apparent differences between the Soviet system and today’s Russia, one important similarity is striking: over the last two decades (after 1999) there has been a visible increase in the belief that it is impossible for a political subject to separate truth from lying and that the sphere of public administration and political interests is, by definition, a place where deception prevails. This article discusses the potential historical roots of this certainty.

Algunos archivos históricos y repositorios de Lima
Authors: Silva Santisteban Fernando
Published: January 2021

Hasta hace poco tiempo, la labor del investigador era verdaderamente ardua, la documentación dispersa y sin la menor guía se guardaba como una cosa vedada; el historiador tenía que defenderse a favor de la suerte y de los archiveros. Para remediar este mal se decidió franquear al público los repositorios de papeles antiguos que poseía el Estado, preocupándose de concentrar en un solo lugar los fondos de diversa procedencia que yacían esparcidos por las distintas oficinas públicas. Fue esta la primera medida que facilitó grandemente la labor de los estudiosos dedicadas a la investigación del pasado peruano; pero hasta la fecha queda mucho por realizar. El informe hacinamiento de papeles es necesario ponerlo en orden, y no sólo esto, sino que se debe también ponerlo en condiciones más favorables para la investigación. La clasificación y catalogación de los documentos es tan importante como la formación de los propios archivos; no basta reunir, hay que acrecentar con nuevas adquisiciones los fondos existentes y ponerlos en las mejores condiciones para aprovechar de ellos toda información histórica.

All happy families are alike, every unhappy family is unhappy in its own way.Leo Tolstoy, “Anna Karenina”Despite the recent rearrangement of the federal districts, the notion “Baikal Region” still exists. The three subjects of the Russian Federation, Zabaikalsky Krai, the Buryat Republic and the Irkutsk Region are united around the lake, which is often called “Great Sea”. This region is our journal’s homeland. The journal’s regional section contains the materials that show typical problems of provincial cities and their solutions.The disunity of citizens and the lack of social communication constitute a key problem that gives rise to a lot of other problems. The project for public spaces in Shilka became the winner of the Federal Competition for Formation of a Comfortable Urban Environment. It is the third annual issue of the Competition organized by the Ministry of Construction, and the level of the projects is trending upward.Another winner of this year is a project for Tulun. The problem related to the flood of 2019 and the wave of social pessimism and depression caused by it is to be solved by the project.Deprived areas with a high level of crime draw urbanists’ attention all around the world. Studying the case of Novo-Lenino in Irkutsk, F. Kudryavtsev and E. Tokareva raise a question about the ways of rehabilitation for the neighborhood.The threats to the cultural and historical heritage compose a complex problem, where developers’ immediate interests, unfair expert reviews, the bureaucracy’s short-term vision, citizens’ indifference etc. are tightly interwoven.

El nombre propio como modulador de vínculos sexo-afectivos y genealógicos en las novelas de Armonía Somers: una poética de la suplementariedad nominal
Authors: Szaszak Bongartz Ulla
Published: January 2021

Este artículo tiene como objetivo explorar la potencia del nombre propio como modulador identitario contingente en la novelística de la autora uruguaya Armonía Somers, y, en específico, de la suplementariedad nominal (el acto de retorcer, sobreimprimir, desplazar o sustituir –a veces de forma momentánea– el nombre “original” o “legal”de los personajes por otro(s), como forma de deriva o fuga nominal). Dicha operación se propone como productora de transformaciones subjetivas de los personajes, tal como se verifica en ciertas zonas del discurso literario latinoamericano del siglo XX. Dentro de éstas inscribo tres novelas de Somers: La mujer desnuda (1950), Sólo los elefantes encuentran mandrágora (1986) y Viaje al corazón del día: elegía por un secreto amor (1986), las cuales participan de dicha poética nominal. En dichos textos, y a partir de los desplazamientos nominales, se verifica la reconfiguración o incluso una inauguración de vínculos inéditos entre los personajes. De modo que el uso de este recurso temático, estructural y subjetivo excede el mero cambio de nomenclatura y se revela como un polo de producción subjetiva e intersubjetiva.
¿Súplica inaudible? Poesía y violencia en poetas colombianas
Authors: Giraldo Luz Mary
Published: January 2021

El impacto de la violencia en Colombia, durante todo el siglo XX, exaltado en la intensidad del conflicto armado impuesto sobre la sociedad y la intimidad desde las décadas de los sesenta y mediados de la segunda del XXI, han sido expresados de diferentes maneras por algunos creadores colombianos. Este documento busca llamar la atención sobre algunas representaciones literarias del tema y los efectos poéticos que ofrecen sus autores, al manifestar conciencia frente al dolor que ha causado la guerra. Conscientes de las repercusiones devastadoras de los homicidios, secuestros y desplazados que la violencia ha generado, los autores asumen su rol creativo señalando el horror y, en el caso de las autoras, el énfasis en algunas de una actitud beligerante, profunda desolación y escepticismo. Los estilos son variados y particulares, pues unas reflejan el temblor suscitado por la angustia y el desasosiego, otras expresan rabia o temor, y otras un sentimiento desesperanzado frente a un universo hecho trizas. Son en general voces que expresar dolor individual y colectivo.
La didactique du roman libertin à travers les expressions figées sur la beauté féminine
Authors: Messina Luisa
Published: January 2021

Le but de notre étude est d’analyser l’importance didactique concernant certaines expressions figées, venant des romans libertins du dix-huitième siècle, dans l’enseignement de la littérature française. Il sert pour identifier non seulement la fonction de la beauté dans la littérature libertine, mais aussi la spécificité d’expressions figées précises, fréquemment utilisées par les romanciers libertins au dix-huitième siècle. À l’exception de Laclos, les écrivains libertins sont traditionnellement exclus des programmes scolaires ou universitaires italiens parce qu’ils ont été longtemps jugés comme scandaleux en raison du sujet de leurs écrits. Ainsi est-il impensable de proposer l’étude de Sade dans l’enseignement secondaire. On veut alors montrer comment ces expressions figées permettent d’aborder la littérature libertine de façon différente.
Presence and specificity of the political communication of the Catalan independence leaders on Twitter in the 2017 regional elections
Authors: Bustos Díaz Javier , Ruiz del Olmo Francisco Javier , Moreno Velasco Miguel Nazario
Published: January 2021

The regional elections in Catalonia held on 21 December 2017 received wide media coverage, far beyond Spanish media, due to separatist tension in that territory and was one of the main topics in most of the world’s media. Within this process social networks, especially Twitter, obtained crucial relevance given the interest aroused by the political leaders’ publications, since in those elections the debate transcended the usual ideological divisions of right and left and became a struggle between constitutionalists and separatists. This paper analyses the presence and influence of the main candidates of the Catalan political parties on Twitter. To achieve this, a mainly quantitative, mixed methodology based on big data was carried out where all the tweets issued by the candidates during the electoral campaign were analysed.

Verificamos, en primer lugar, los desfasajes recurrentes entre las representaciones y lo que concretamente se realiza en el aula. En segundo lugar, docentes en ejercicio y docentes residentes ponen de manifiesto diferentes propuestas y estrategias de enseñanza sobre la lectura y la escritura. Por último, concluimos que la literatura presenta un claro predominio como ámbito de intervención didáctica, afectando la formación en el lenguaje en su funcionamiento social y sus usos.
World-Class Fe-Ti-V Oxide Deposits Formed in Feeder Conduits by Removing Cotectic Silicates

Published: January 2021

Extremely thick Fe-Ti-V oxide layers are hosted in mafic-ultramafic intrusions of the Emeishan large igneous province (LIP) in the Pan-Xi district of southwest China, accounting for a quarter of the world’s Ti and V resource. It is unclear why these small intrusions contain such huge ore reserves that form world-class Fe-Ti-V oxide deposits. We find that the Hongge intrusion contains 35% Fe-Ti-V oxides, which is twice the typical content in mafic-ultramafic intrusions worldwide and the experimentally determined cotectic proportion in natural ferrobasaltic magma systems. The V content is almost constant in titanomagnetite across the entire Hongge intrusion in the Emeishan LIP, indicating a small (10–20%) proportion of cotectic Fe-Ti-V oxide during fractional crystallization. The bulk composition of the intrusion indicates an open magma system at the time of its formation. Clinopyroxene phenocrysts from overlying basalts contain Fe-Ti-V oxide inclusions, indicating that the phenocrysts crystallized at depth from magma saturated in Fe-Ti-V oxide and were then transported to the surface. We suggest that these intrusions were feeder conduits to the overlying basalts, where the silicates were cotectic with Fe-Ti-V oxides which were then extracted from the underlying intrusion as phenocrysts. Such a fundamental process is key to increase the proportion of oxide minerals in the residual assemblage, thereby upgrading the barren oxide-bearing rocks to world-class Fe-Ti-V oxide deposits in the small intrusions of the Emeishan LIP. A similar process might have occurred in LIPs elsewhere, meaning that intrusions formed as conduit-like open systems to the basalts in LIPs are good exploration targets for giant high-grade Fe-Ti-V oxide deposits.

Introduction: Splenectomy, whatever the reason, is an absolute indication for vaccination against encapsulated bacteria in order to prevent overwhelming post-splenectomy infections. This study aimed to determine compliance to immunization guidelines for splenectomy in General Surgery Clinics. Materials and Methods: In this observational cross-sectional study, we included patients who underwent splenectomy between April 2016 and April 2018, and recorded the patient data and vaccination status. Results: Splenectomy was performed in 65 patients, 40 (61.5%) were male and median age was 56 (19-90) years. Six of the operations were emergent, 21 were planned and 38 were urgent mostly due to solid organ malignancy. Only 14 (21.5%) patients were vaccinated with Haemophilus influenzae, meningococcal and pneumococcal vaccines according to the guidelines (≥2 weeks before the operation). 14 of the 21 patients (66.6%) who underwent planned splenectomy were vaccinated appropriately. Conclusion: Compliance with vaccination guidelines was low before splenectomy operations. There is a room for improvement particularly for patients undergoing elective splenectomy. A patient-centered team strategy is required to vaccinate patients at the stage of splenectomy planning.
As representações da violência policial no dossiê Megaeventos e violações dos direitos humanos no Rio de Janeiro em 2015
Authors: Lacerda Igor , Fortuna Érica
Published: January 2021

Este trabalho tem o objetivo de identificar e analisar as representações das violências policiais ocorridas no Rio de Janeiro, através do dossiê Megaeventos e violações dos direitos humanos, criado pelo Comitê Popular da Copa e das Olimpíadas em 2015. O propósito é entender melhor como os moradores da cidade se uniram para representar esse período de megaeventos, com as transformações que estavam afetando suas vidas. Para identificar essas representações, foi utilizada a análise de conteúdo segundo Laurence Bardin (2016). Para interpretar os dados obtidos, recorremos à teoria de representações sociais, segundo Sandra Jovchelovitch (2000). Esse estudo é relevante por explicar uma fase de transformação do Rio não pela visão da mídia hegemônica, mas pela percepção de seus próprios moradores.
Os ditos, os não-ditos e os modos de dizer a crise pós-Lava-Jato na revista Petrobrás
Authors: Pinheiro Lidiane
Published: January 2021

O envolvimento do alto escalão da Petrobras com crimes diversos tornou-se conhecido com a Operação Lava Jato. A empresa conhecida pelo slogan “o desafio é a nossa energia” passou a ter um novo desafio no âmbito comunicacional: o que dizer, o que não dizer e como dizer a crise provocada pelas denúncias de corrupção para os seus públicos? A pesquisa tem por objeto os discursos da Petrobras sobre a crise e visa entender os não-ditos, os enunciados e os modos de enunciar da companhia em tal contexto. O artigo realiza a análise dos discursos da Revista Petrobras, de 2014 a 2016, e observa que a organização constrói um discurso nacionalista e elogioso de si, a partir de uma projeção metonímica do seu corpo funcional, confundindo-o muitas vezes com a própria empresa, mas exigindo dele engajamento
Entre a farofa e a tour do cofre:

Published: January 2021

Discute-se neste artigo a criação de um imaginário ancorado em um conjunto de práticas sociais, especialmente de apropriações do meio. Mais especificamente, o trabalho se propõe a refletir sobre um conjunto de usos, apropriações e códigos constatados no campo de observação, tendo em vista que o objeto empírico trata-se de um grupo no Facebook, o LDRV. Como subsídio teórico acionamos autores que discutem questões da midiatização e, através das análises, percebe-se que os modos de significação e de acionamento de elementos do imaginário do grupo em questão, estão intrinsecamente ligados as lógicas de midiatização.
Narrativas transmídia e competências midiáticas
Authors: Martins Vanessa Coutinho , Thomé Claudia de Albuquerque
Published: January 2021

A nova ambiência comunicacional, fruto da cultura digital, atravessou a produção e o consumo de narrativas literárias, que se expandem para as redes e são (re)criadas pelos prosumidores (SCOLARI, 2016). O artigo analisa os comentários das transmissões no Periscope do Wizarding World Book Club, clube do livro de Harry Potter, na comemoração aos 20 anos de lançamento do primeiro livro da saga. Com auxílio da metodologia de Ferrés e Piscitelli (2015), o estudo busca entender como os prosumidores percebem o conteúdo oferecido através do live streaming, e, consequentemente, produzem mensagens. A análise aponta para um senso crítico na produção das mensagens pelos prosumidores e conclui que as características no âmbito da expressão foram mais frequentes do que em outros aspectos analisados.
100 mil mortes: o saldo negativo da Covid-19 nos telejornais brasileiros
Authors: Freitas Viviane Gonçalves , Baptista Érica Anita
Published: January 2021

O foco deste artigo está na cobertura feita por três importantes telejornais do Brasil - Jornal Nacional, Jornal da Band e Jornal da Record - quando do anúncio das 100 mil mortes em consequência da Covid-19, marca atingida em 8 de agosto de 2020. Nosso objetivo foi compreender como se deu a disputa político-discursiva do noticiário, uma vez que a linha editorial de cada veículo também se reflete na agenda encampada por seu principal produto jornalístico. Mais do que abordagens distintas, a análise do corpus possibilitou entender como cada telejornal acionou um tipo de interdiscurso alinhado a seu público, seja adotando a perspectiva de cobrar às autoridades governamentais pela efetivação do direito universal à saúde, seja mostrando que é possível encontrar algo positivo na quarentena.
Manifestations of Middle School Learners’ Problematization Activity as an Embodied Phenomenon
Authors: Valentine Keri Duncan , Theodore J. Kopcha
Published: January 2021

Current reforms in geometry seek to challenge prevailing ideas about “what it means to do mathematics” (Stephan et al., 2015, p. 139) by engaging learners in “the grasping of space” (Freudenthal, 1973; Hansen et al., 1998, p. 241). This study takes up this challenge by investigating problematizing activity as an embodied phenomenon among 21 eighth-grade learners who engaged with spatial and dimensional concepts during a series of investigations around Flatland. Using a phenomenological research approach, we examined classroom discourse as well as learners’ blog postings, lived-experience descriptions, and interviews. The analysis revealed three manifestations of problematizing activity—provocation, impasse, and questioning and conjecturing activity. Embodiment was evidenced through perceptuo-motor-imaginary activity as learners juxtaposed naturally continuous space with discrete notions of space emphasized in K−12 settings.
A Framework for Investigating Qualities of Procedural and Conceptual Knowledge in Mathematics—An Inferentialist Perspective
Authors: Nilsson Per
Published: January 2021

This study introduces inferentialism and, particularly, theGame of Giving and Asking for Reasons(GoGAR), as a new theoretical perspective for investigating qualities of procedural and conceptual knowledge in mathematics. The study develops a framework in which procedural knowledge and conceptual knowledge are connected to limited and rich qualities of GoGARs. General characteristics of limited GoGARs are their atomistic, implicit, and noninferential nature, as opposed to rich GoGARs, which are holistic, explicit, and inferential. The mathematical discussions of a Grade 6 class serve the case to show how the framework of procedural and conceptual GoGARs can be used to give an account of qualitative differences in procedural and conceptual knowledge in the teaching of mathematics.
Teaching Classes in Geometry to Solve Original Exercises

We all realize, I presume, that we have a difficult problem before us. I feel that I shall be more likely to say something that you will care to listen to if I confine myself largely to personal experience. I will however give a little theory at the outset.
Vocational Courses in Mathematics for Secondary Schools
Authors: Smith David Eugene
Published: January 2021

Professor Smith stated that it was his intention to speak rather upon the general problem than upon any details. He stated that the problem of the industrial mathematics was a new one in all new countries, but an old one in the older civilizations. The reason why the problem is new here is that a country like ours tends to consider the individual more than the state, whereas in various older countries the opposite is the case. All types of vocational training have been thought to arrest the development of the individual, and this has actually been the case in certain types of schools in Europe.
