Reflexiones de futuros maestros sobre la idoneidad didáctica y modo de uso de una lección de libro de texto
Authors: Castillo María José , Burgos María
Published: May 2022

Resumen Una lección de libro de texto describe el proceso instruccional previsto para el estudio de un contenido, por lo que constituye un recurso relevante para los docentes, que deberán ser críticos cuando decidan cómo emplearla en su planificación curricular. En este estudio se describen y analizan las reflexiones que hacen futuros maestros sobre el grado de adecuación de una lección de libro de texto de proporcionalidad, su modo de uso y los cambios que llevarían a cabo para incrementar la idoneidad didáctica del proceso instruccional implementado. El análisis cualitativo de sus informes escritos permite identificar las referencias a criterios de idoneidad didáctica que incluyen en sus valoraciones. Los resultados reflejan que los futuros maestros reflexionan correctamente sobre aspectos epistémicos (falta de argumentación, falta de claridad en la presentación de conceptos, poca variedad de situaciones y representaciones), cognitivos (falta de atención a conocimientos previos, no advertencia de errores y dificultades al alumno) e instruccionales (la lección prioriza el aspecto procedimental y deja interacciones entre alumnos en segundo plano). Aunque la mayoría identifica conflictos semióticos en la lección y reconoce que el texto debe ser un recurso sobre el cual ha de realizarse cambios para una gestión eficiente, las modificaciones que proponen refieren sólo de modo parcial a la valoración realizada previamente, priorizando cambios en lo epistémico (variar tipología de tareas) y cognitivo (incluir resúmenes de contenidos previos). Concluimos este estudio con una propuesta de mejoras para posteriores intervenciones formativas.

Approaching the sensory profile of Paipa cheese, the Colombian ripened cheese with protected designation of origin
Authors: Benavides-Sánchez Diego Alejandro , Pena-Serna Carolina
Published: May 2022

Abstract Paipa cheese is the unique Colombian ripened cheese produced from raw milk that has a protected designation of origin (PDO); nonetheless, to date, the dairy product lacks a defined sensory profile, since no study has been previously performed. The aim of this study was to approach the definition of the sensory attributes of the Paipa cheeses that are produced within the PDO region in order to establish the organoleptic aspects of the PDO regulation. A trained panel of five members used the multidimensional approach as a descriptive sensory analysis to establish the sensory profile of Paipa cheese; such analysis was complemented with the method used for PDO cheeses were three cheese producers, two government delegates, one gastronomy expert and two Paipa cheese researchers participated in the descriptive sensory analysis. A microbiological assessment (mesophilic aerobic bacteria, lactic acid bacteria, total and fecal coliforms, coagulase-positive Staphylococci, Salmonella spp. and Listeria monocytogenes) of cheese samples was carried out prior to sensory analysis to guarantee the safety of the samples. The descriptive sensory analysis was performed with 17 cheese samples that represented 77% of Paipa cheese produced in the PDO region. 82 sensory descriptors were identified and 47 were finally established (seven descriptors for appearance, 15 for odor, 15 for taste and 10 for texture) for describing the sensory profile of Paipa cheese. Due to the presence of pathogenic bacteria, the texture and taste profiles of Paipa cheese were based only on three samples. Sensory profiles of cheese samples were highly heterogeneous and it may be a consequence of the variations among raw milk used and/or manufacturing practices of cheese producers. Therefore, in order to find the sensory identity of Paipa cheese and guarantee quality and safety, cheese production and raw milk characteristics must be defined and regulated among milk and Paipa cheese producers.

Abstract This study aimed to produce pectin and alginate microparticles by ionic gelation coated with different concentrations of bovine blood and egg white protein in their natural state. The coated microparticles were characterized, and their physical resistance and morphology were evaluated, as well as the released protein during in vitro gastrointestinal simulation. The highest protein adsorption (65.47%) was shown by pectin microparticles coated with bovine blood (10%), regardless of the protein type and concentration used. Likewise, higher amounts of adsorbed protein resulted as protein concentration increased, regardless of the type of microparticle. Nevertheless, the physical resistance of coated microparticles was affected more by the type of polysaccharide, being alginate microparticles more resistant. Adsorbed proteins on microparticles surface showed higher solubility values in vitro gastrointestinal simulation regardless of protein type. Bovine blood and egg white proteins in their natural state can be used as alternative coating materials for microparticles.

Authors: Graminha Pedro Brandão , Afonso Luís Eduardo
Published: May 2022

RESUMO Objetivo: este trabalho analisa como os efeitos de enquadramento, de ancoragem e de certeza podem influenciar o comportamento do consumidor de seguro de automóveis. Métodos: foi realizado um experimento, com a aplicação presencial de seis versões de um questionário com 14 questões, para 163 respondentes de uma instituição de ensino. Foram elaboradas perguntas visando a analisar a existência dos efeitos de ancoragem, de certeza e de enquadramento, além do efeito de franquia (presente em diversos ramos de seguros). O arcabouço teórico do trabalho é a economia comportamental. Resultados: as pessoas mais jovens, os(as) solteiros(as) e os homens possuem maior propensão ao risco. Embora os achados de forma geral corroborem as evidências da literatura, os resultados sobre o efeito de certeza foram contrários ao esperado. O pagamento da franquia aumentou a aversão ao risco dos respondentes. Conclusões: a existência de vieses e heurísticas pode fazer com que a aquisição de seguros ocorra de forma não ótima. O conhecimento do processo de tomada de decisão é importante para as seguradoras e para os consumidores. Também é relevante para os reguladores, com a finalidade de subsidiar medidas que visem à eficiência do mercado e à proteção dos consumidores, por meio do desenho de uma arquitetura de escolhas adequada.
Expectations, Economic Uncertainty, and Sentiment
Authors: Franco Douglas de Medeiros
Published: May 2022

ABSTRACT Objective: this article aims to help unravel if and how economic uncertainty interacts with the informational structure of sentiment. Methods: the empirical strategy is based on a non-linear and non-parametric causality test to investigate the interaction between variables as distributions. This article builds primarily on the literature on expectation formation. Results: it was found that uncertainty based on the media (ex-ante) precedes sentiment, at most, until the second moment of its distribution. In addition, sentiment helps predict the informational structure of fundamental uncertainty (ex-post) and higher order moments of ex-ante uncertainty. Conclusion: sentiment can be considered a channel for uncertainty through the tone of expectations and erroneous expectations. Ex-ante uncertainty measures can also help calibrate the rational cost-benefit calculation of attention by acting as a leading indicator of the increasing value of information.

Published: May 2022

RESUMO Objetivo: o presente artigo pretende ajudar a desvendar se e como a incerteza econômica interage com a estrutura informacional do sentimento. Métodos: a estratégia empírica baseia-se em teste de causalidade não linear e não paramétrico para investigar a interação entre as variáveis enquanto distribuições. Este artigo constrói principalmente a partir da literatura sobre formação de expectativas. Resultados: foi encontrado que a incerteza com base na mídia (ex-ante) antecede o sentimento, no máximo, até o segundo momento de sua distribuição. Além disso, o sentimento ajuda a prever a estrutura informacional da incerteza dos fundamentos (ex-post) e momentos de ordem superior da incerteza ex-ante. Conclusão: sentimento pode ser considerado um canal para incerteza através do tom das expectativas e de expectativas errôneas. Medidas de incerteza ex-ante podem ainda ajudar a calibrar o cálculo racional custo-benefício da atenção ao atuar como indicador antecedente do maior valor da informação.
Nudge Policies in COVID-19 Context: A Necessary Action or Ethical Dilemma?
Authors: Correa Ana Luize , Ames Maria Clara F. Dalla Costa , Zappellini Marcello Beckert
Published: May 2022

ABSTRACT Objective: the aim of this study is to discuss nudges in the SARS-CoV-2 pandemic context, bringing back some reflections on ethics and revising them in the light of the new setting imposed by the pandemic. Theoretical approach: the theoretical framework of Behavioral Economics was the basis for nudges’ analysis, while utilitarianism, deontology, and virtue ethics were the classic moral theories used to reflect on ethical aspects. Methods: we undertook a literature review about nudges searched through the latest studies about this subject applied to COVID-19 mitigation. In the ethical discussion section, we used classical references to articulate the nudge theory with the following moral theories: utilitarianism, deontology, and virtue ethics. Results: our findings indicate that the trend intervention during the pandemic is ‘nudging messages’ and ‘increase people’s commitment,’ mainly to nudge people toward the desired behavior and increase policy adherence. Many experiments did not show significant results, and some drawbacks in policies’ applications indicate that nudges might be revised in crisis scenarios, such as a pandemic outbreak. The ethical discussion section relates three moral theories that justify some of the nudge’s aspects. Conclusions: this paper showed some flaws and inconsistencies in nudge theory and its application during the pandemic that can be solved by discussing ethical aspects. We suggest that connecting these problems with moral views might be a solution for some deadlocks found in the nudge theory.
Comparative analysis of patients’ survival on hemodialysis vs. peritoneal dialysis and identification of factors associated with death
Authors: Vicentini Carolina Aparecida de Almeida , Ponce Daniela
Published: May 2022

Abstract Introduction: There are several studies comparing the outcomes of patients treated with peritoneal dialysis (PD) and hemodialysis (HD), and most are divergent. Methods: This is a cohort study that followed patients with incident PD and HD in a planned and unplanned way, in a dialysis unit of the HCFMB from 01/2014 to 01/2019, until the outcome. We collected clinical and laboratory data. The PD and HD groups, death and non-death outcomes, were compared using the chi-square test for categorical variables and t-test, or Mann-Whitney test for continuous variables. Kaplan Meier curve and log-rank test were used for survival. Multivariate analysis was performed using the Cox regression. The significant difference was p < 0.05. Results: We had 592 patients, 290 treated by HD and 302 by PD. The mean age was 59.9 ± 16.8, with a predominance of males (56.3%), the main underlying disease was diabetes (45%); 29% of the patients died. There was no difference in the survival of patients treated by HD and PD. The oldest age (1.018 (95% CI 1.000-1.037; p=0.046)) was identified as a risk factor for death, while the highest number of infection-free days (0.999 (95% CI 0.999-1.000; p=0.003 )) as a protective factor. Conclusion: The analysis reinforced that the survival of patients on HD and PD was similar. Higher age and shorter infection-free time were associated with death.

Conclusão: A análise reforçou que a sobrevida dos pacientes em HD e DP é semelhante. Foram associados ao óbito a maior idade e o menor tempo livre de infecção.
As virtudes terapêuticas do ananás em escritos franciscanos e jesuíticos entre os séculos XVI e XVII
Authors: Cardoso Janaina Salvador
Published: May 2022

Resumo A Ordem dos Frades Menores e a Companhia de Jesus foram duas das quatro principais ordens religiosas que se instalaram em terras brasílicas ao longo do século XVI. Reconhecidos por suas missões evangelizadoras e pelas contribuições com a expansão da fé católica nos trópicos, franciscanos e jesuítas também foram responsáveis pela redação de crônicas, tratados e cartas em que relataram suas principais impressões sobre a América portuguesa. Nessas páginas que eram enviadas aos seus confrades residentes na Europa, os clérigos letrados não escreveram apenas questões relativas à atuação das ordens, mas contemplaram todo o mundo natural com o qual se depararam, como as espécies vegetais pouco ou totalmente desconhecidas aos olhares europeus. Ao reunirmos escritos produzidos por franciscanos e jesuítas a partir de 1549, buscamos apreender as principais impressões, usos e virtudes medicinais que esses homens atribuíram aos pomos brasílicos. Dos cajus, araçás e demais frutas tropicais que compuseram estes escritos, contemplaremos especialmente as narrativas sobre o ananás, fruta nativa do Brasil e muito admirada pelos colonos que por aqui viveram. Assim, desejamos compreender quais narrativas e conhecimentos sobre o ananás foram produzidos pelos padres e freis que visitaram o Novo Mundo brasílico entre os séculos XVI e XVII.
“Vestindo a camisa da empresa”: neoliberalismo e a subjetividade dos trabalhadores shoppers

Published: May 2022

Resumo O presente artigo visa compreender a subjetividade do trabalhador shopper, avançando na análise da uberização no cenário brasileiro e dos impactos do neoliberalismo no tecido social e urbano. Observamos como os shoppers descrevem suas atividades, quais relações estabelecem com as plataformas e colegas e de que forma manifestam sua identidade. Para tanto, analisamos dois trabalhadores que narram questões sobre esse tipo de trabalho em canais do YouTube . As conclusões sinalizam que as incertezas vivenciadas nesse contexto se convertem em indefinições quanto às suas identidades profissionais, que se somam a um contexto urbano dominado pela falta de proteção de milhões de trabalhadores, por vezes vistos a si mesmos como empreendedores de suas próprias vidas que buscam construir alternativas de renda e trabalho.
Urban walkways designed by João Batista Vilanova Artigas
Authors: Tagliari Ana , Florio Wilson
Published: May 2022

Abstract Modern architects operate with at least three fundamental notions: space, time, and movement. In the case of the walkways, the challenge is also to solve the problems of walkability in specific topographic constraints of the city. Based on documents available in the library collection of the School of Architecture and Urbanism of the University of São Paulo, this study analyzed the urban walkways designed by Vilanova Artigas in the 1970s for the city of São Paulo and the region known as ABC Paulista. The value of these walkways in Artigas’ work lies not only in the designed and constructed object, but also in his theoretical thought about circulation, connection, city, people, and architecture. A table was created with the drawings of the walkways and their main circulation elements. This study contributes to the appreciation of our architectural and modern urban heritage.

Published: May 2022

Resumo A produção de habitação nas metrópoles brasileiras apresenta vinculação à expansão e ao fortalecimento do setor imobiliário nos espaços urbanos, muitas vezes independentemente dos ciclos econômicos do País. Porto Alegre não foge ao padrão brasileiro; entretanto, este artigo verifica a hipótese de Molotch, denominada “Máquina de Crescimento”. Para isso, examina e discute a dinâmica imobiliária e a construção habitacional na última década na cidade de Porto Alegre. Utilizam-se como referência dados do Sinduscon-RS, além dos dados sobre a produção habitacional do Programa Minha Casa Minha Vida (PMCMV) entre 2009 e 2020. A partir da hipótese, demonstra-se a importância que os setores ligados à dinâmica imobiliária têm na produção do espaço na cidade.
A regulação do mercado imobiliário e política habitacional no Rio de Janeiro
Authors: Aragão Thêmis Amorim
Published: May 2022

Resumo O problema habitacional no Brasil, nas últimas duas décadas, tem aumentado. O déficit habitacional absoluto no País passou de 5,657 milhões, em 2016, para 5,877 milhões em 2019. A pesquisa aqui apresentada tenta problematizar o papel do Estado não somente como promotor de habitação de interesse social, mas também como agente regulador do mercado imobiliário que envolve tanto o setor de vendas quanto o setor de aluguéis. Este artigo visa colocar em pauta que, sem o controle do Estado sob mecanismos de acesso ao mercado formal de imóveis, a produção de novas unidades habitacionais para baixa renda é apenas uma medida mitigadora para as restrições que o mercado impõe aos trabalhadores.
METAMORFOSES DO AMARELO: A IMIGRAÇÃO JAPONESA DO “PERIGO AMARELO” À “DEMOCRACIA RACIAL”
Authors: Hayashi Bruno Naomassa
Published: May 2022

Resumo Tomando como marcos a Constituinte de 1946 e a Sessão Legislativa de 1958, este artigo busca entender as radicais transformações vividas pelos imigrantes japoneses e seus descendentes nos primeiros anos pós-guerra. Se, em 1946, a imigração japonesa ficou muito próxima de ser constitucionalmente proibida, em 1958, o legislativo federal será marcado por celebrações comemorativas do cinquentenário dessa imigração para o Brasil. A partir dos discursos de deputados e senadores, desejo identificar como e sob quais fundamentos os parlamentares procuravam distanciar ou aproximar da nacionalidade brasileira os japoneses e seus descendentes. O olhar sobre o legislativo permitirá, ainda, verificar as consequências de cada visão nas proposições concretas apresentadas, discutidas e votadas no Parlamento. As mudanças nas concepções raciais e de nacionalidade que dominam, em cada momento, os debates e deliberações no legislativo federal brasileiro serão centrais para a compreensão do processo.
“ Acompanho o Meu Partido ”: Organização Partidária e Comportamento Legislativo no Brasil
Authors: Ribeiro Pedro Floriano , Locatelli Luís , Assis Pedro Paulo de
Published: May 2022

RESUMO Componentes centrais no funcionamento dos governos partidários, a unidade e disciplina das bancadas são geralmente explicadas a partir de fatores macro institucionais e variáveis endógenas ao legislativo. No entanto, os parlamentares são eleitos por meio de listas partidárias – abertas, no caso brasileiro, – e há diferenças entre seus partidos em termos de estrutura decisória e robustez organizacional. O artigo analisa os impactos da democracia interna e da força organizacional dos partidos (filiados, receitas e diretórios) sobre a unidade e a disciplina das bancadas na Câmara dos Deputados. Os resultados da análise multivariada sugerem que quanto menos democráticos são os partidos, e quanto mais robustas são as organizações, maiores serão as taxas de unidade e disciplina das bancadas. A força da organização partidária indica aos parlamentares quais são as consequências potenciais (volume de recursos) de comportamentos desertores, enquanto o nível de centralização e democracia interna afeta a eficácia dos mecanismos de enforcement para punição ou recompensa dos membros das bancadas (acesso aos recursos). Os achados sugerem que as diferenças organizacionais entre os partidos podem estar associadas a diferentes níveis de unidade e lealdade verificados na arena parlamentar.

La construcción compartida del conocimiento se enmarca en la pedagogía del socioconstructivismo, no obstante, presenta determinadas características que deben ser analizadas; más aún, en el contexto de la pandemia por COVID-19, que ha condicionado una educación no presencial de emergencia apoyada en las TIC. En esa dirección, el presente estudio tuvo como objetivo analizar la construcción compartida del conocimiento en entornos virtuales de aprendizaje en estudiantes de educación básica de dos instituciones estatales del distrito de Santa Anita, perteneciente a la Unidad de Gestión Educativa Local 06, Lima-Perú. En una investigación básica, cuantitativa, no experimental y comparativa, se evaluó a 260 estudiantes pertenecientes a los tres últimos años de educación secundaria, mediante la aplicación de un cuestionario en línea, el cual cuenta con una validez por juicio de expertos y una confiabilidad que indica una excelente consistencia interna. Los resultados obtenidos evidencian que existe una escasa construcción compartida del conocimiento a través de los entornos virtuales de aprendizaje, asimismo; se demuestra que no existen diferencias estadísticas en la construcción compartida del conocimiento en Entornos Virtuales de Aprendizaje según las instituciones educativas de procedencia, así como según los grados de estudio. Sin embargo, se demuestra que existen diferencias estadísticamente significativas en cuanto al género.

Published: May 2022

Relevance In conditions of elevated ambient temperatures, a solar battery operating at temperatures above 40 °C reduces the output power by –0.45 % / °C. In the conditions of an isolated hybrid power supply system, this fact can lead to a significant loss of power in the network from heating solar cells and costs, since an additional source of power supply as part of Hybrid Renewable Energy Systems (HRES) is a diesel power plant. Aim of research The main aim of the research to investigate the effect of elevated ambient temperatures and reduced temperature of thermoelectric elements on the solar panel in the MatLAB Simulink environment, to calculate the approximate energy efficiency from the method used as part of hybrid power supply systems based on renewable energy sources (HRES). Research methods As a mathematical model, it is proposed to use the MatLAB Simulink complex, as a device for reducing the temperature of the solar module, it is proposed to use thermoelectric elements. Results Based on mathematical calculations in the MatLAB Simulink environment, with the help of thermoelectric elements, it was possible to increase the maximum power by 0.11 kW, which, according to approximate calculations, will save the equivalent of diesel fuel in the amount of 267,000 rubles in the period from April to September for the village of Kuskurgul with a consumption of 100 kW.

Published: May 2022

The data on the composition of the ichthyofauna and relative quantity of common species of fishes in the littoral and the upper sublittoral zones in the coastal waters of the South-Eastern Kamchatka are provided basing on the analysis of the results of hook catches, collections made in the intertidal zone, and underwater photo- and video records performed in the May – September 2021. The obtained results show that the impact of the negative effect of harmful algal bloom in the autumn of 2020 on the composition of the species and quantity of fishes, inhabiting the intertidal zone, is very insignificant. Unfavorable ecological conditions in the upper sublittoral zone (2–25 m) in the South-Eastern Kamchatka in the autumn 2020 caused decrease the quantity of some fishes (mainly species of the family Stichaeidae) which hide on the bottom in the rock crevices or are buried in silty-sand bottom. But unfavorable ecological conditions practically had no influence on the quantity and mode of life of the representatives of ichthyofauna which were able to leave temporarily the coastal waters with harmful algal bloom areas.

Published: May 2022

[RETRACTED]

Peptides are ideally suited to mimic natural ligands and usually act in an antagonistic or agonistic manner. Small active peptide molecules have huge potential to be developed as vaccines, diagnostic reagentsand lead compounds. Therefore, peptides have become the highlight of drug discovery, especially due to their small size, structural diversity and high specificity for a given target. Moreover, peptides can be selected from large natural or artificial peptide libraries rapidly, and are easy for chemical processing and synthesis. Application Peptides are capable of physiologically destroying functional complexes due to their small size and specific binding properties. Peptides perform a variety of biological functions in the body, such as metabolism, digestion, respiration, reproduction, immune defense and many other functions by acting as ligands (such as hormones, neurotransmitters, cytokines, and chemokines).

This SOP describes the procedure for generating cDNA from SARS-CoV-2 viral nucleic acid extracts and subsequently producing 400nt amplicons tiling the viral genome using V4.1 nCov-2019 primers (ARTIC) in multiplex PCR. Illumina-compatible sequencing libraries are then made directly from these amplicons in a second PCR step, obviating the need for conventional library preparation. The products of these PCRs are then equivolume pooled and quantitated, prior to sequencing on the Illumina NovaSeq. It is an adaptation of the COVID-19 ARTIC v3 amplicon protocol which can be found here: https://www.protocols.io/view/covid-19-artic-v3-illumina-library-construction-an-bibtkann Both the above protocols were adapted from the nCov-2019 sequencing protocol: https://www.protocols.io/view/ncov-2019-sequencing-protocol-bbmuik6w

Creative Cognition and Emotions: A Stage Based Comparison v1
Authors: Kumar Mritunjay
Published: May 2022

A wealth of research indicates that emotions play an instrumental role in creative problem-solving. However, most of these studies have relied primarily on diary studies and self-report scales when measuring emotions during the creative processes. There has been a need to capture in-the-moment emotional experiences of individuals during the creative process using an automated emotion recognition tool. The experiment in this study examined the process-related difference between the creative problem solving (CPS) and simple problem solving (SPS) processes using protocol analysis and Markov’s chains. Further, this experiment introduced a novel method for measuring in-the-moment emotional experiences of individuals during the CPS and SPS processes using facial expressions and machine learning algorithms. The experiment described in this study employed 64 participants to solve different tasks while wearing camera-mounted headgear. Using retrospective analysis, the participants verbally reported their thoughts using video-stimulated recall. Our results indicate differences in the cognitive efforts spent at different stages during the CPS and SPS processes. We also found that most of the creative stages were associated with ambivalent emotions whereas the stage of block was associated with negative emotions. This protocol contains the supporting data and files that can be used to replicate this study.

Low cost methods for Hydra care v2
Authors: Hyland Callen , DeSantis Jennifer
Published: May 2022

Hydra is genus of freshwater cnidarian polyp found in lakes, ponds, and streams all over the world. Its remarkable ability to regenerate missing body parts, and even its whole body from fragments, has made Hydra a model system for regeneration and development for over 250 years. Despite their anatomical simplicity, much about Hydra’s basic biology and extraordinary regeneration caption remains mysterious. The simplicity of caring for and doing experiments on Hydra makes it an accessible subject for undergraduate research, high school lab activities, or even a home hobbyist. This collection of protocols describes low-cost methods for maintaining Hydra cultures, including step-by-step instructions for preparing media, growing brine shrimp for feeding to Hydra, and caring for your Hydra colonies. We’ve focused on equipment that can be found in most high school and college labs, or consumer products that can be purchased online. Experiments on Hydra can be incredibly simple. Much can be learned from dissecting a Hydra and observing its regeneration. Hydra’s response to varying environmental conditions can also be explored in a classroom setting with minimal resources. These simple experiments can be a bridge to cutting-edge molecular biology and stem cell research. Sequencing of the Hydra genome has opened the door for genetic manipulations and large-scale bioinformatics studies. Transgenic lines with fluorescently-labeled cell types and proteins, including neuron and muscle activity reporters, are available.
