Self-Assembly of a Cd2+Compound with 4-Pyridylthioacetic Acid: Structural and Luminescence Properties
Authors: Tzeng Biing-Chiau , Yeh Hsien-Te
Published: February 2022

An interesting 3-D supramolecular architecture has been constructed through O-H・ ・ ・O and S・ ・ ・S weak interactions based on a neutral 1-D coordination polymer, [Cd(pyta)2(H2O)]n (pyta = pyridylthiocarboxylate), by self-assembly of the Cd2+ion and Hpyta ligand. This supramolecular approach is achieved in combination of coordinative bonds, O-H・ ・ ・O and S・ ・ ・S interactions. The tetragonal unit of 1-D coordination polymers forms a 1-D channel structure with a dimension of 5.35×6.86 Å2in the solid state, leading to the formation of zeolite-like materials. In combination with the zeolitelike nature of the title compound as well as its luminescence behavior, it is expected to find useful applications in luminescence sensing for VOCs (volatile organic compounds).

Authors: Greve Jan , Näther Christian
Published: February 2022

The new copper(I) coordination polymer poly[tri-μ2-cyano-C,N)-bis(μ2-2,3-dimethyl-pyrazine- N,N)] tricopper(I) (I) was prepared by the reaction of copper(I) cyanide with 2,3-dimethylpyrazine in acetonitrile. In the crystal structure of Ia novel CuCN substructure is found which is connected by the dimethylpyrazine ligands into a three-dimensional coordination network. The thermal properties of Iwere investigated using simultaneous differential thermoanalysis (DTA), thermogravimetry (TG) and mass spectrometry (MS) as well as temperature resolved X-ray powder diffraction. On heating, compound Ilooses a part of the dimethylpyrazine ligands in an endothermic reaction to form the known ligand poor compound (CuCN)2-(2,3-dimethylpyrazine) IIas an intermediate which decomposes to CuCN on further heating.

The chemical investigation of the ethanol/water (7:3) extract of the roots of Detarium microcarpum (Fabaceae) led to the isolation of one new labdane diterpenoid, microcarpin (1) and one new ceramide derivative, microcarpamide (2), along with eight known secondary metabolites (3–10) including, 5-(carboxymethyl)-5,6,8a-trimethyl-3,4,4a,5,6,7,8,8a-octahydronaphthalene-1-carboxylic acid (3), microcarposide (4), rhinocerotinoic acid (5), 1,7-dihydroxy-6-methylxanthone (6), ursolic acid (7), 3β,23-dihydroxylup-20(29)-en-28-oic acid (8), alphitolic acid (9), and stigmasterol glucoside (10). The structures of these compounds were elucidated based on their spectroscopic data. Although compounds 3 and 4 are known, their crystalline structures are reported here for the first time. These compounds were evaluated in vitro for their antisalmonella activity. The results obtained showed that, microcarpamide (2), microcarposide (4), and rhinocerotinoic acid (5) were moderately active against three salmonella strains: Salmonella typhi, Salmonella enteritidis and Salmonella typhimirium, with minimum inhibition concentration values of 76.7 and 153.5 μM.
The development of effective ruminant breeding programmes in Ireland from science to practice
Authors: Berry D.P. , Dunne F.L. , McHugh N. , McParland S. , O’Brien A.C. , Twomey A.J.
Published: February 2022

A genetic improvement programme is a sustainable, cumulative and permanent approach to achieving year-on-year performance gains. Its success is predicated not only on an efficient and effective breeding programme but also on a vision of the traits of importance in the future. A single, industry-owned, centralised database for cattle and sheep has been the foundation for genetic improvement programmes in Ireland. While DNA information has been heralded as a breakthrough for accelerating genetic gain, the basic principles of a successful animal breeding programme still remain the same: (1) a pertinent breeding goal, (2) the appropriate breeding objective to deliver on the breeding goal, (3) an accurate genetic evaluation system, (4) an efficient and effective breeding scheme, and (5) a system to disseminate the elite germplasm to the end user; also of importance is a system for validating the underlying procedures and principles. The constituent traits and their relative emphasis within breeding objectives will continue to be contentious. Traits that will need to be considered more in future ruminant breeding objectives include environmental impact, product quality and animal well-being, including health; while not always explicitly included in Irish breeding objectives for cattle and sheep, indirect improvements for many are expected via the genetic improvement in traits like reproductive performance and survival as well as macro measures of quality such as milk fat and protein concentration and carcass merit. Crucial for the future sustainability of ruminant production systems is the co-evolution of management systems and breeding programmes so that the animal of the future is suited to the most sustainably efficient production system.
Učebnice pod kontrolou. Politické ideje jako východisko obsahového vymezení učebnic
Authors: Vojtko Tibor
Published: February 2022

Every political establishment seeks to control the ideological and educational content of textbooks. With its decrees, the Ministry of Education defined the ideological and educational content of textbooks and determined control over them. The article focuses on changes in the content definition of the ideological basis of state educational policy, i.e. the ideological direction of the concept and interpretation of the curriculum in textbooks in Czechoslovak history between 1918 and 1960. The analysis of educational documents showed that in the regulations for the content and approval of textbooks, political-social influence is due to (a) ideological conflicts, (b) broader dispute about the social and socio-political direction of society (socialism vs. capitalism), (c) cult of personality, (d) the importance of school education for the individual and the state, and (e) the role of the individual (citizen) for society and the state.
Okresní školní inspektor a počátky státního dohledu nad obecným školstvím v Čechách v letech 1869–1873
Authors: Klečacký Martin
Published: February 2022

The paper deals with the adoption of School Supervision Act from 1869 in Bohemia, taking into account both Czech and German speaking milieus. Using the example of appointment of District School Inspectors and looking into their activities, it analyses the system deficiencies and complications that the state authorities had to cope with in the first years after adoption and that, eventually, led into an amendment of the aforementioned act four years later. Apart from the inadequate organisational background and salary conditions of district inspectors, the paper points out the financial requirements that the school reform brought about and that had to be covered mostly by local municipalities. This fact significantly contributed to a generally passive or even negative attitude held by autonomous corporations as for the new school legislature implementation, which was enhanced by oppositional stance of Czech political representation.
Škola a výchova v Německé demokratické republice
Authors: Geißler Gert
Published: February 2022

The German Democratic Republic, which emerged in 1949 from the eastern occupation zone in divided Germany, was the most western state in the Soviet sphere of influence. The article traces how a new, independent, and efficient school system emerged from a common German history. In constant political competition with the Federal Republic of Germany, it initially demonstrated a strong affinity with the Soviet school system, in which educational practices were rooted in the doctrinal principles of a Marxist-Leninist pedagogy.
Rewarding More Is Better for Soliciting Help, Yet More So for Cash Than for Goods: Revisiting and Reframing the Tale of Two Markets With Replications and Extensions of Heyman and Ariely (2004)
Authors: Imada Hirotaka , Chan Wan Fei , Ng Yuk Ki , Man Lee Hing , Wong Mei Sze , Cheng Bo Ley , Feldman Gilad
Published: February 2022

Heyman and Ariely (2004) demonstrated that the expected effectiveness of soliciting help varied depending on the “market”, a money market represented by cash rewards versus a social market represented by goods as rewards. They showed that, as cash rewards increase, individuals expected others to be more willing to help, yet, when offering social goods as rewards such as candy, expected willingness to help was insensitive to rewards’ monetary worth. We conducted two pre-registered replication studies (total: N = 3302, MTurk/Prolific) of Study 1 in Heyman and Ariely (2004) and found support for one of their main claims that people are more sensitive to worth when the reward is cash than goods. However, the rewards’ monetary worth impacted expected willingness to help even in social markets, deviating from the original findings. Extensions further compared between-subject and within-subject designs, examined perceived affect (joy and regret), and added a new control condition. We concluded that higher compensation is generally perceived as better when soliciting help, yet more so for the money market cash rewards than for the social market goods rewards.

Establishment and Validation of a Predictive Model for Long-Term Severe Functional Tricuspid Regurgitation after Mitral Valve Replacement
Authors: Liu Qiqi , Chen Shuang , Shen Wenqian , Duan Xin , Ren Xingxing , Sun Zeya , Tian Jiawei , Xue Jingyi , Du Guoqing
Published: February 2022

Background: The objective was to develop and validate an individualized nomogram to predict severe functional tricuspid regurgitation (S-FTR) after mitral valve replacement (MVR) via retrospective analysis of rheumatic heart disease (RHD) patients’ pre-clinical characteristics.
Methods: Between 2001-2015, 442 MVR patients of RHD were examined. Transthoracic echocardiography detected S-FTR, and logistic regression model analyzed its independent predictors. R software established a nomogram prediction model, and Bootstrap determined its theoretical probability, which subsequently was compared with the actual patient probability to calculate the area under the curve (AUC) and calibration plots. Decision curve analysis (DCA) identified its clinical utility.
Results: Ninety-six patients developed S-FTR during the follow-up period. Both uni- and multivariate analyses found significant correlations between S-FTR occurrence with gender, age, atrial fibrillation (AF), pulmonary arterial hypertension (PH), left atrial diameter (LAD), and tricuspid regurgitation area (TRA). The individualized nomogram model had the AUC of 0.99 in internal verification. Calibration test indicated high agreement of predicted and actual S-FTR onset. DCA also showed that utilization of those six aforementioned factors was clinically useful.
Conclusion: The nomogram for the patient characteristics of age, gender, AF, PH, LAD, and TRA found that they were highly predictive for future S-FTR onset within 5 years. This predictive ability therefore allows clinicians to optimize postoperative patient care and avoid unnecessary tricuspid valve surgeries.
Properties of torsion rod in "Sulzer” projectiles loom
Authors: ElNashar ElSayed A , Pirogov Dmitry
Published: February 2022

The torsion rod characteristics of the Sulzer loom can be adjusted in the zero position by means of the adjusting lever and the adjusting actuator of the torsion rod of loom. In the "Sulzer" projectile loom, the movement of the intermediate member results in the axial movement of the adjusting lever to change the position of the zero according the material and characteristics of rod. The intermediate member transmits a force exerted by the adjusting lever to a fixed sliding surface. However, the described device in some countries has a serious drawback, because the tuning drive acts on the torsion rod adjusting lever so that when the projectile is fired into the “Sulzer” loom, the picking mechanism reacts through the sudden, harmful pressure of the tuning drive. A solid wedge-shaped idler that can be moved by the adjusting motor is placed between the sliding surface of the adjusting lever and a fixed sliding surface. In the "Sulzer" projectile loom, known torsion rod control enables projectile loom operation with improved energy consumption and reduced wear.
Tiempo, tarea y satisfacción. De la sindéresis a la medición de resultados
Authors: Mercado Juan-Andrés
Published: February 2022

Polo explica la sindéresis como un principio proactivo. Para ser constructiva, la efusividad humana requiere disciplina individual y estructuras organizativas. Una relación armónica entre la inteligencia y las emociones constituye una plataforma para la esperanza y la gratificación. Las emociones indican que las acciones y las producciones positivas producen satisfacción y perfeccionan a los trabajadores. Los directivos deben promover actividades que lleven a cumplir los objetivos. Fijar objetivos estructura el tiempo a través de instrumentos muy variados, para que los trabajadores puedan dar más y seguir dando, es decir, sin desgastarse innecesariamente. La metodología OKR concreta algunas nociones antropológicas fundamentales de Polo, a través del establecimiento de objetivos y estrategias para medir los resultados de modo que los trabajadores crezcan en autonomía e iniciativa. La retroalimentación que se da con este sistema de trabajo promueve la confianza y la asimilación de las gratificaciones por los resultados alcanzados.

Authors: Costa Natalí Nascimento Gonçalves , Servo Maria Lúcia Silva , Figueredo Wilton Nascimento
Published: February 2022

ABSTRACT Objective: To analyze Brazilian and international scientific publications about the stress experienced by health professionals in the hospital context during the COVID-19 pandemic. Methods: Integrative literature review carried out on the SciELO, ScienceDirect, and LILACS databases, and sources of official Brazilian institutions, with documents published by May 2020. Results: Of the 26 selected references, 19 (73.08%) were indexed articles, and 7 (26.92 %) were obtained from official institutions. The study found that stress is mainly due to the overload of hospital services, the removal of professionals, the insufficiency of personal protective equipment and strict biosecurity measures, challenges in the allocation of available resources, and the risk of contamination by COVID-19. Final considerations: The stress experienced by health professionals in hospital institutions during the pandemic can trigger occupational and psychological problems.

Published: February 2022

ABSTRACT Objectives: to unveil the meanings of mothers whose children died as a result of domestic accidents in childhood. Methods: a qualitative research, in the light of Heideggerian phenomenology, with ten mothers whose children died from domestic accidents. It was carried out in a municipality of the Northeast Region of Brazil through phenomenological interviews between May and June 2017. The existential analytic was constituted by the comprehensive moments of the Heideggerian method. Results: the meanings unveiled pointed out that, to understand the sudden death of her child, the mother oscillates between feeling guilty, pointing and denying guilt. She reports emptiness, permanent pain, non-acceptance of her child’s death, and the desire to keep him in her life. In this journey, the fear that brings limitations to her life and that of her other children is revealed. Final Considerations: it was revealed that the death of the child in infancy compromises the integrality of being a mother, indicating the need for systematic and continuous care for the adequate management of the emotional and social effects.

Fomento à ciência, tecnologia e inovação (CT&I) : mapeamento de políticas públicas no combate à pandemia de COVID-19 no âmbito estadual
Authors: Gonçalves-Alvim Silmary de Jesus , Marino Pedro de Barros Leal Pinheiro
Published: February 2022

Resumo: Este trabalho investigou as políticas públicas estaduais e distritais de fomento à CT&I voltadas ao combate à Covid-19 e implementadas durante a pandemia. Foram mapeadas 118 ações públicas nas 27 unidades federativas brasileiras. A maioria das ações eram restritas à esfera de atuação estadual ou distrital (71%). As demais contemplaram articulações no âmbito federal (19%), internacional (8%) ou regional (2%). Somente duas ações utilizaram instrumentos que foram considerados inovadores para o contexto de CT&I brasileiro. A primeira política, proposta pela Secretaria de Estado de Inovação, Ciência e Tecnologia do Rio Grande do Sul, utilizou um instrumento de Autoridade e Tesouro para instituir o “Programa Inova RS”. Este instrumento de fomento à CT&I foi baseado em regulamentos elaborados pelos órgãos financiadores e envolveram transferências de recursos financeiros entre governo, ICTs, indivíduos, empresas e outros tipos de organizações. A outra política, implementada pela Secretaria de Estado de Desenvolvimento Econômico, Ciência e Tecnologia do Estado de São Paulo, fez uso de um instrumento de Autoridade e Nodalidade para instituir o “Programa IdeiaGov”. Nesta política, os governos utilizaram recursos procedimentais e a organização de informações, garantindo o acesso de parte da população aos espaços de produção de políticas e permitindo maior controle social sobre a gestão pública, sem envolver transferência de recursos públicos. Por fim, foi verificado o alinhamento destes novos instrumentos aos temas de pesquisa prioritários para a Organização Mundial da Saúde.
A substancialização dos conceitos psicanalíticos: efeitos e impasses
Authors: Silva Thiago Pereira da , Moschen Simone Zanon
Published: February 2022

Este artigo se insere em um debate atual acerca das políticas conceituais do campo lacaniano. Ele procura explorar um dos traços distintivos desse debate: a crítica à progressiva tematização da insuficiência da linguagem e à substancialização dos conceitos psicanalíticos no movimento lacaniano, identificada no trabalho de alguns psicanalistas. Este trabalho, por sua vez, apontaria para outra leitura do texto lacaniano, vetorizada por um horizonte ético-epistemológico distinto, marcadamente antisubstancialista. Destacaremos nisso o lugar de uma política dos usos de três conceitos fundamentais a esse campo: real, gozo e corpo. A partir das articulações propostas, procuraremos apresentar o substancialismo como um obstáculo em potencial para a psicanálise lacaniana, além de explorar algumas de suas possíveis implicações éticas, clínicas e epistemológicas.
Pecado, crime e patologia: produções discursivas acerca da perversão
Authors: Vale André Luiz Alexandre do , Cardoso Marta Rezende
Published: February 2022

Baseando-nos nas análises genealógica e epistemológica propostas por Foucault e Lantéri-Laura, nosso objetivo principal é discernir quais são as principais linhas discursivas que constituíram o saber em torno da perversão, produzindo um sujeito dito perverso. Emerge de maneira fundamental dessa leitura como a ideia de transgressão de limites acompanha a história dos perversos: seja o limite moral imposto pela autoridade divina, seja o limite jurídico determinado pela lei penal, seja o limite do normal definido pela medicina, a perversão sempre aponta para o excesso transgressor. Tais leituras constituem o solo epistemológico sobre o qual Freud se apoia na concepção de uma metapsicologia cujo eixo central é a sexualidade. O discurso freudiano subverte o estatuto da perversão ao afirmá-la como dimensão inescapável da sexualidade e da constituição da subjetividade humana.

Published: February 2022

ABSTRACT The Characidium orientale Buckup & Reis, 1997 larvae development is described using specimens collected in the natural environment of Antas River, in the Taquari-Antas river basin, Rio Grande do Sul, Brazil. Were considerate ontogenetic changes in morphology, pigmentation, fin morphology, and meristic characters. Thirty-six larvae (33 in the preflexion stage, two in flexion, and one in the postflexion stage), with a standard length between 4.24 and 11.26 mm were analyzed. The larvae of C. orientale are altricial and present fusiform body, subterminal mouth, long intestine with anal opening posterior to the vertical line over the median region of the body. Two chromatophores are evident in the interorbital region, as well pigments concentrated on the side of the body, forming a longitudinal stripe, and between the rays of the caudal fin, which intensify during the development. Also, a conspicuous remnant of the embryonic membrane (finfold) in front of the dorsal fin appears to be characteristic of species of the genus during larval development. The total number of myomeres varies from 32 to 35 (18-23 pre; 11-16 postanal). The main changes in morphometry occur during the preflexion stage and suggest physiological and behavioral changes.

Partidos e instituições nas políticas viárias em São Paulo - 1978/2016
Authors: Marques Eduardo Cesar Leão , Almeida Gabriela Trindade de
Published: February 2022

RESUMO Introdução: Esse artigo analisa as políticas de infraestrutura viária no município de São Paulo em 12 governos ao longo de 38 anos (1978-2016). A literatura sobre políticas públicas urbanas é pouco desenvolvida, em grande parte pelo escasso diálogo teórico entre a ciência política e os estudos urbanos. Esse artigo contribui para o campo ao analisar os principais elementos políticos e institucionais que cercam uma política pública central para o funcionamento das cidades e suas dinâmicas de poder. Materiais e Métodos: O trabalho se baseia em entrevistas com atores do setor, consultas a documentos e levantamento primário dos contratos do poder público com empreiteiras, coletados diretamente no Diário Oficial do Município. Resultados: A análise dos investimentos indica que essas políticas são explicadas principalmente por duas dimensões combinadas. Por um lado, por distinções político-ideológicas entre governos, que imprimiram preferências e ênfases em diferentes tipos de programas. A principal diferença se dá entre os governos de direita e os demais, com os primeiros concentrados em obras maiores e mais caras, contratadas com empreiteiras de maior porte e concentradas em certos tipos de obras. Por outro lado, a política foi fortemente influenciada pela crescente influência de instituições e instrumentos de política pública recentes, que geraram insulamento das contratações e alavancaram volumes substanciais de recursos adicionais para a política. Discussão: Os resultados confirmam a relevância de argumentos da teoria do governo partidário, mas também a urgência da incorporação de elementos institucionais na análise de políticas urbanas.

ABSTRACT Processing of poultry products requires a severe microbiological quality control, considering they are one of the main sources of foodborne infections. The objective of this research was to perform the isolation of enterobacteria in broiler carcasses from commercial establishments in the Metropolitan Region of Fortaleza in Ceará State, Brazil. Broiler carcasses were collected and selected as fresh (n = 14), refrigerated (n = 18) and frozen (n = 19). Carcasses were submitted to a rinsing method, followed by pre-enrichment and enrichment with Rappaport-Vassiliadis and Selenite-Cystine, streaked on plates with Brilliant Green, MacConkey and Salmonella-Shigella agars, and to a presumptive biochemical identification. It was verified that all broiler carcasses categories presented enterobacteria contamination, with the following frequency of isolation: Proteus sp., 66.7%; Enterobacter sp., 15.7%; Citrobacter sp., 2%; Escherichia coli, 47.1%; Klebsiella sp., 11.8%; Shigella sp., 5.9%, and Salmonella sp. 11.8%. It was observed that no combination of culture media was able to detect all enterobacteria contamination in the broiler carcasses. Thus, it may be necessary the use of several combinations of culture media to determine the real microbiological quality of broiler carcasses.

ABSTRACT The objectives of the present trial were to evaluate the reproductive parameters in a Holstein bovine herd affected by leptospirosis during the outbreak of abortion and stillborn fetus and treated with streptomycin sulfate. Animals were divided in 2 groups of 10 cows each: G1, treated with streptomycin sulfate 25 mg/kg/lw for 3 days by IM route; and; G2, untreated control. Serum samples were collected on the onset of abortions and after that every 15 or 30 days until completing 270 days. Samples were analyzed by means of MAT microscopic agglutination test that showed sera conversion to serovar Canicola with titers ranging from 100 to 51,200; 7/20 of the urine samples were positive for Leptospira spp. by PCR After streptomycin sulfate therapy, the outbreak ended and urine samples also got negative to PCR and no fetus samples were positive in either techniques. However, it did not influence the evolution in antibody titers of serological profiles in both groups, which got negative after around 200 days of the onset of symptoms. Although there was no significant difference of the frequency of pregnancy/AI and calving/pregnancy rates between treated and untreated groups (p > 0.05), reproductive rates were lower in the untreated group.

RESUMO O objetivo do presente trabalho foi avaliar o efeito do crômio em diferentes concentrações na forma de levedura de crômio na resposta imune humoral anti-rábica em bovinos. Utilizaram-se 60 novilhas da raça Nelore (Bos indicus) com idade média de 2 e 5 anos, alimentadas em pastagem de Brachiaria decumbens, com fornecimento da água de bebida e sal mineral ad libidum, divididas aleatoriamente em 4 grupos de 15: grupo controle (Gc) que receberam o sal mineral sem crômio, os demais grupos receberam sal mineral contendo 8,5, 17 e 34 mg de crômio/kg de sal, grupos G8,5, G17 e G34, respectivamente. Todos os bovinos receberam no dia 0 uma dose de vacina comercial anti-rábica inativada. Colheram-se amostras de sangue nos dias 0, 30, 60 e 90 e os títulos de anticorpos anti-rábicos foram determinados por meio do teste de soroneutralização em camundongos. Os resultados obtidos mostram que as novilhas do grupo G17 apresentaram diferenças significativas no título de anticorpos anti-rábicos, no entanto, somente o G 34 mostrou persistência dos títulos de anticorpos protetores, 90 dias após a vacinação. Os resultados obtidos permitem concluir que o crômio aumentou o título de anticorpos neutralizante anti-rábico e que a melhor concentração estudada foi 34 mg de Cr/kg de sal mineral.

Published: February 2022

RESUMO Em maio de 1999, foram realizadas análises físicas e químicas da água em nascentes e lagos do Parque Dr. “Fernando Costa” (Parque Água Branca) São Paulo, SP, com o objetivo de determinar sua qualidade e propor medidas de preservação. Para tanto, foram escolhidos 6 pontos amostrais, na superfície e fundo do Lago Negro, nas nascentes da Horta e do Ranário e nos Tanques do Chafariz e das Carpas. Os maiores níveis de oxigênio dissolvido foram encontrados no Lago Negro (12 na superfície e 12,70 mg/L no fundo), sendo que apenas nas nascentes estes valores foram inferiores ao estipulado pela legislação CONAMA 357/2005, para Águas Doces Classe III (> 4 mg/L). Somente do Lago Negro, tanto na superfície quanto no fundo, foram encontrados valores de cor acima do limite estipulado pela legislação (até 75 mg Pt/L). Altos valores de DBO5 foram encontrados apenas nos Tanques das Carpas (9,29 mg/L) e do Chafariz (11,22 mg/L). Para todos os ambientes, os valores N-NO2 estiveram acima do limite estabelecido (1 mg/L), sendo que, em relação ao N-NO3, somente nas nascentes estes valores foram iguais ou superiores ao limite estabelecido (10 mg/L). Através da análise dos resultados, foi possível observar que as águas do Parque Água Branca apresentam boa qualidade para fins ecológicos e paisagísticos. Entretanto, o crescimento urbano desordenado, sem considerar a preservação de nascentes e áreas verdes, e o elevado aporte de matéria orgânica, principalmente no Lago Negro, são fatores relevantes na perda de qualidade da água. Somente um planejamento urbano aliado a um programa de educação ambiental, poderá auxiliar na melhoria das condições ecológicas e sanitárias desta importante área verde na região central de São Paulo.

Resumo: Introdução: O processo de ensino-aprendizagem passou por grandes mudanças tecnológicas ao longo das décadas, com importante impacto nos cursos de Medicina. Uma dessas mudanças foi o uso dos ambientes virtuais de aprendizagem (AVA). Objetivo: Este estudo teve como objetivo avaliar a qualidade do processo de ensino-aprendizagem remoto no curso de Medicina durante a pandemia da Covid-19. Método: É um estudo de caráter descritivo com abordagem quantitativa e qualitativa. Seu desenvolvimento foi dividido em quatro fases: revisão da literatura, desenvolvimento do protocolo de avaliação, coleta e análise dos dados. A coleta de dados foi realizada por meio de um formulário on-line, e a análise dos dados, por análise estatística em três eixos: a avaliação do perfil tecnológico, a avaliação da aceitação da tecnologia e a experiência do usuário. Resultado: Foi constatado que a maioria dos estudantes (65%) e docentes (88.2%) possuía infraestrutura para participar do semestre suplementar. A maior parte dos alunos relatou sentir segurança em utilizar as ferramentas tecnológicas e estava satisfeita com o ensino remoto, porém 53% dos alunos relataram não ter um rendimento tão grande quanto teriam em um período presencial comum, além de terem mencionado dificuldades na adaptação ao ensino remoto, e 40,2% citaram uma alta taxa de problemas psicológicos entre eles. Os docentes em sua maioria se sentiam seguros em lecionar on-line e também tiveram uma avaliação em geral bastante positiva do semestre remoto, tendo apenas algumas discordâncias em relação ao tempo para preparação das aulas e da criação de materiais didáticos para seus alunos. Conclusão: Os diversos fatores relacionados à tecnologia, organização e saúde mental dos estudantes e docentes devem ser levados em consideração no planejamento dos próximos semestres, pois, até que a situação de saúde volte ao normal, os próximos semestres letivos terão todos os componentes teóricos do curso de Medicina trabalhados remotamente, ao menos com a maioria na modalidade híbrida. É provável que alunos e professores desenvolvam uma curva de aprendizagem e consequente adaptação, o que pode atenuar algumas das dificuldades observadas. É preciso que o processo de adaptação seja catalisado por normas, orientações e também inovações da universidade.
Upcoming Issues, New Methods: Using Interactive Qualitative Analysis (IQA) in Management Research
Authors: Behling Gustavo , Lenzi Fernando César , Rossetto Carlos Ricardo
Published: February 2022

ABSTRACT Objective: this article aims to present interactive qualitative analysis (IQA) as a qualitative strategy to be used in management research, detailing its application. Since the IQA is a strategy derived from research in education, this study discusses the potentialities of its use in management research. Methods: the IQA is presented by the step-by-step application of the method in a research problem in entrepreneurship. Results: the IQA targets the generation of a shared mental map of the focus group members on the phenomenon under study. The data collection and analysis steps are conducted in parallel, and the research participants themselves carry out the first analysis. The results presented in a set of relationships between the elements of the shared mental map are theorized. The inductive character of the initial stages, combined with deductive procedures, allows discovering new ways of thinking about the investigated problems, reinforcing qualitative research’s exploratory character. Conclusions: the replicable data collection and analysis protocol promotes researches’ reliability and validity, by presenting empirical evidences that the interpretations are guaranteed by the data, allowing for methodological and theoretical advances.
Memes as Shortcut to Consumer Culture: A Methodological Approach to Covert Collective Ideologies
Authors: Deus Elisa Priori de , Campos Roberta Dias , Rocha Ana Raquel
Published: February 2022

ABSTRACT Objective: the paper proposes the methodological use of memes as a shortcut to explore consumer culture. Memes as cultural texts can reveal collective circulating ideologies that may not be accessed through regular interviews. Context: memes are cultural texts that convey easy-to-understand messages, gaining strength within social networks. Cultural texts playfully present the social context and beliefs of societies. We analyzed circulating memes during the COVID-19 pandemic about elderly consumers in Brazil to outline a methodological protocol. Method: we analyzed memes adopting the discourse model to conduct qualitative research of memes as a shortcut to cultural discourses. We collected memes during March and May 2020 using social media networks. They were classified following thematic analysis. Result: the proposal is a methodological procedure for analyzing memes as a cultural text. The process starts with the outline of a data collection protocol, followed by data analysis guidelines, illustrated by the context of elderly consumers. Conclusion: the analysis of memes as cultural texts contributed to understanding of consumer behavior through current cultural content, revealing contrasting ideologies that emerge from consumers, as covert value-systems, circulating alongside institutional mass-mediated ideologies.
The Qualitative Approach Interview in Administration: A Guide for Researchers
Authors: Cheron Cibele , Salvagni Julice , Colomby Renato Koch
Published: February 2022

ABSTRACT Context: this paper explores different ways of using qualitative approach interviews, based on the assumption that the interview is not exclusively subjective or objective, but intersubjective, allowing participants to discuss and express their interpretations about the social world. Objective: the aim is to guide the use of the interview, step by step, in research in administration and related areas, offering a simplified guide to assist beginning and experienced researchers. Method: due to its objective, this tutorial article is descriptive and explanatory, interdisciplinary and supported by bibliographic sources. Results: theoretical considerations about the interview are made, conceptualizing essential aspects related to its structuring, development and evaluation. Also listed are the factors resulting from the intersubjectivity inherent in the act of researching, such as the potential types of interview, the dimensions of the preparation, the different possibilities of asking, the questions about the conduct of the meeting, the dimensions related to the analytical work, among others. Conclusion: as an outcome, it is suggested that the interviewer observe the asymmetry of the relationship with the interviewee, the inevitable presence of biases and distortions, and the rigor in planning the investigation.
Clues for the Paradigmatic Development of Online Qualitative Methods
Authors: Melo Newton Claizoni Moreno de , Dourado Débora Coutinho Paschoal
Published: February 2022

ABSTRACT Objective: in this paper, we problematize how online methods were reduced to mere adaptations from previous data collection techniques, and then discuss how some of the idiosyncratic properties of the online scope may drive the development of future, paradigmatic, online qualitative methods. Proposition: we identified five clues for the paradigmatic development of online qualitative methods: (1) the new socialities allowed by online interactions; (2) the processes involved in asserting identities and selves online; (3) the increasing difficulty in distinguishing what is private and what is public online, and what does privacy mean in this context; (4) the increase of participants’ agency in online qualitative research; and (5) the declining distinction between offline and online social phenomena. Conclusion: by using ontological and epistemological assumptions that do not consider the specificities of online experiences, and by focusing excessively on adapting known methods to the new settings, we researchers are bound to conceive the online experience and operate in it using offline categories. This way, we might be missing the opportunity to develop native, paradigmatic, online qualitative methods that, ultimately, would allow for a better understanding of the phenomena we investigate.

Effect of hydrogel microcapsule on shrinkage and mechanical properties of cement mortars
Authors: Jing Wu , Xiong Wu , Jianfeng Ma , Da Gao , Yaoling Luo
Published: February 2022

Superabsorbent polymer (SAP) shows a good internal curing effect in cement-based materials, but its volume changes greatly after it releases water. This occurrence causes adverse effects on the properties of cement-based materials. Microcapsules were prepared with calcium alginate hydrogel as the shell and epoxy resin as the core material to mitigate these adverse effects. The effects of microcapsules on the shrinkage and mechanical properties of cement mortars were analysed by observing such parameters as the heat of hydration and relative humidity of the mortars, and such techniques as mercury intrusion porosimetry. The results showed that microcapsules can delay the hydration of cement and provide a superior early shrinkage reduction effect when compared with SAP. In addition, the presoaked microcapsules left pores that were smaller in diameter than those observed in the SAP mortars. As a result, the influence of microcapsules on the mortar's compressive strength was found to be less than that of SAP. Therefore, the compressive strength of the mortars containing microcapsules was essentially the same as that of the mortars containing SAP when the presoaked microcapsule content was 35 times that of the presoaked SAP content.
Harmonious Relationships: Sounds and Stones in Ottoman Architecture in the Making
Authors: Kale Gül
Published: February 2022

Architectural narratives on building processes are admittedly rare in premodern histories. Accounts of visitors who observed and reacted to architecture in the making are even more exceptional. Moreover early modern audiences’ perceptions of music and architecture have been rarely explored in relation to building processes and synesthetic experiences. This article presents a critical reading of Caʿfer Efendi’s Risāle-i Miʿmāriyye [Book on Architecture] of 1614 by focusing on its chapter on the Sultan Ahmed mosque (1609–17) in Istanbul. Caʿfer associates sounds in the construction site with Sufi musical practices and the science of music. A conversation with a Sufi at the site reveals how twelve types of marbles, four types of strikes, and seven types of foremen were associated with Ottoman music theory. The article also explores how the shared geometrical foundations of architectural tools and musical instruments were linked to harmonious sounds and forms. This union of spatial, visual, and aural experiences of the mosque in the making produced various forms of knowledge for the visitors. Architecture’s mediating role for sensuous, spiritual, and scientific knowledge further illuminates the relation between theory and practice in Ottoman architecture.
