Facilitators’ use of a communication device following children's aided turns in everyday interaction
Authors: Pilesjö Maja Sigurd , Norén Niklas
Published: May 2021

This conversation analysis study investigates facilitators’ simultaneous use of speech and aided means in instructional interaction with children with complex communication needs (CCN), who use aided communication in an everyday setting. The participants were children with severe speech impairments and their everyday communication partners. The analysis focused on facilitators’ aided turns immediately following aided turns by the children, within so-called retro-sequences. Retro-sequences were found in interactions involving four out of nine children. The facilitators systematically combined a spoken turn with an aided turn, a speaking and pointing (SAP) practice. The pointing consisted of a single graphical word, mostly a noun. The multimodal practice generally highlighted, emphasized, or exposed graphical words that increased noticeability and understandability within the local context. Adult repeats were treated as requests for confirmation of a candidate understanding and were responded to by the child using vocal and embodied resources. Reformulations (recasts) were treated as profferings of candidate understandings and were responded to using the communication device. The findings indicate that the partner's use of a spoken and aided follow-up action shaped the immediate context for device use. The findings are relevant for the design of naturalistic interventions and may be used to improve treatment descriptions in augmentative and alternative communication (AAC) interventions.

Authors: Gundogdu Mustafa , Cansever Sumeyye , Karaavcı Muhammed Salih , Ertas Umit
Published: May 2021

Patients who have undergone maxillary resection procedures are rehabilitated with dental obturators or microvascular reconstruction. This case report describes implant-supported prosthetic rehabilitation of a patient who underwent maxillary resection because of squamous cell carcinoma. After maxillectomy surgery, the patient was rehabilitated using a surgical obturator for 1 week, followed by an interim obturator until the surgical field was completely healed. For definitive prosthesis, different treatment options were presented from which the patient selected an implant-supported maxillofacial prosthesis and a removable mandibular partial prosthesis. Under general anesthesia, 2 zygomatic implants and 4 conventional implants to the posterior maxilla were inserted. After a healing period, the bar-retained maxillofacial prosthesis and removable mandibular partial denture were fabricated. The patient was satisfied regarding function, esthetics, speech, and swallowing. No problems, except slight discoloration of the prosthesis, were noted at the 6-month follow-up. Implant-supported maxillofacial prostheses are a valuable treatment option to improve quality of life after maxillary resection.

ABSTRACT Objectives: to know the care implemented by the nursing team to prevent medical device-related pressure injuries in critically ill patients. Methods: this is a qualitative research conducted with 15 nursing professionals from Intensive Care Unit. Sampling was carried out by theoretical saturation. For data analysis, the Discourse of the Collective Subject technique was used. Results: six speeches emerged, whose central ideas were interventions for medical device-related pressure injury prevention: care in fixation; frequent repositioning; protection and padding of body areas in contact; preferences for flexible materials, when available; attention of professionals so that they do not comer under patients; early assessment and removal, when clinically possible. Final Considerations: nursing care was directed mainly to respiratory devices, catheters in general and monitoring equipment, indicating that professionals have the knowledge to provide safe assistance consistent with the literature.

Published: May 2021

O objetivo deste estudo foi avaliar as características das redes de saúde de quatro grandes municípios brasileiros (Campinas, Fortaleza, Porto Alegre e São Paulo) no que diz respeito à prestação de cuidados em saúde mental. Foram usados como desfechos: (i) local de identificação do problema de saúde mental; (ii) atendimento em saúde mental na atenção básica; (iii) assistência farmacêutica em saúde mental; e (iv) reinserção social. Trata-se de um estudo analítico de métodos mistos, de abordagem concomitante e sequencial, conduzido com 10 gestores e 1.642 usuários de Centros de Atenção Psicossocial (CAPS) dos municípios citados. Observou-se a persistência de serviços de alta complexidade, tais como os hospitais, como locais de identificação inicial dos problemas de saúde mental em Campinas (40% dos usuários) e Fortaleza (37%); baixa proporção de tratamento de saúde mental na atenção básica (Fortaleza, 23%); diferenças entre os municípios no que diz respeito à prescrição de medicamentos psicotrópicos na atenção básica (Porto Alegre, 68%; São Paulo, 64%; Campinas, 39%; Fortaleza, 31%), bem como na falta dos medicamentos prescritos (maior em Fortaleza, 58%; menor em Campinas, 28%); e fragilidade em geral na retomada de atividades laborais (menor em São Paulo, 17%; maior em Campinas, 39%), havendo melhores resultados em geral em relação a atividades religiosas e de lazer (maiores em São Paulo, 53% e 56%, respectivamente). É um estudo que contribui para a discussão do panorama brasileiro da assistência à saúde mental, com evidências da persistência de desigualdades no contexto nacional, e aponta lacunas em algumas configurações das redes de saúde mental com potenciais para melhor desempenho e seguimento longitudinal.

Abstract: This paper describes the history, objectives and methods used by the nine Brazilian cohorts of the RPS Brazilian Birth Cohorts Consortium (Ribeirão Preto, Pelotas and São Luís) Common thematic axes are identified and the objectives, baseline periods, follow-up stages and representativity of the population studied are presented. The Consortium includes three birth cohorts from Ribeirão Preto, São Paulo State (1978/1979, 1994 and 2010), four from Pelotas, Rio Grande do Sul State (1982, 1993, 2004 and 2015), and two from São Luís, Maranhão State (1997 and 2010). The cohorts cover three regions of Brazil, from three distinct states, with marked socioeconomic, cultural and infrastructure differences. The cohorts were started at birth, except for the most recent one in each municipality, where mothers were recruited during pregnancy. The instruments for data collection have been refined in order to approach different exposures during the early phases of life and their long-term influence on the health-disease process. The investigators of the nine cohorts carried out perinatal studies and later studied human capital, mental health, nutrition and precursor signs of noncommunicable diseases. A total of 17,636 liveborns were recruited in Ribeirão Preto, 19,669 in Pelotas, and 7,659 in São Luís. In the studies starting during pregnancy, 1,400 pregnant women were interviewed in Ribeirão Preto, 3,199 in Pelotas, and 1,447 in São Luís. Different strategies were employed to reduce losses to follow-up. This research network allows the analysis of the incidence of diseases and the establishment of possible causal relations that might explain the health outcomes of these populations in order to contribute to the development of governmental actions and health policies more consistent with reality.

Abstract: This is a cross-sectional study investigating the factors affecting brazilians’ self-rated health during the COVID-19 pandemic, based on data from the web-based behavior survey. Carried out from April 24 to May 24, 2020, the survey recruited participants by a chain sampling procedure. Its outcome was the worsening of self-rated health during the pandemic. Statistical analysis was based on a hierarchical model of determination. Logistic regression models were used to test the associations between sociodemographic characteristics, pre-existing health conditions, lifestyle indicators and intensity of social restraint measures, and biological and psychological issues during the pandemic. From the total sample of 45,161 participants, 29.4% reported worsening of health state during this period. After adjusting for hierarchical distal factors, the health problems mostly associated with worsening health state were: bad self-rated health (adjusted OR = 4.35, p < 0.001), health care seeking for mental health problem (adjusted OR = 3.95, p < 0.001), and for COVID-19 (adjusted OR = 3.60, p < 0.001). People who experienced sleep problems, worsening of back pain, depression and at least one flu symptom during the pandemic were twice as likely to report worsening of health status. Sedentary and eating behaviors and adherence to social distancing measures showed significant correlation with the outcome. There exists a relation between social, biological, and psychological factors, mediated by lifestyles and variables pertaining to confinement. Altogether, these factors have negatively affected self-rated health during the COVID-19 pandemic in Brazil.

Published: May 2021

Resumo: Apesar de as crianças serem apontadas como o grupo menos afetado pelos sintomas da COVID-19, embora não ileso à doença e suas formas graves, seu cotidiano foi afetado de várias formas, incluindo a interrupção da vida escolar presencial e o contato com colegas de aula, além de impactos relacionados ao isolamento social e, em muitos casos, problemas financeiros e de saúde enfrentados por familiares. Neste trabalho, temos como objetivo compreender a percepção de crianças cariocas sobre o SARS-CoV-2, a COVID-19 e os vírus em geral, por meio de um estudo qualitativo. Entrevistamos 20 crianças por meio de plataformas de serviços de conferência. Os resultados indicam que elas estão conscientes dos riscos e cuidados necessários para a prevenção do coronavírus, mostrando-se apreensivas, com medo de pegar a doença e passar para os seus familiares. Quanto aos vírus em geral, observamos que suas percepções são relacionadas diretamente ao coronavírus, isto é, à situação com que estão lidando atualmente. O estudo traz subsídios que podem ajudar na concepção de estratégias de divulgação científica.

Authors: BOROCHOVICIUS ELI , TASSONI ELVIRA CRISTINA MARTINS
Published: May 2021

RESUMO: A Aprendizagem Baseada em Problemas (ABP) é um método de ensino e aprendizagem que busca o desenvolvimento de conteúdos conceituais, procedimentais e atitudinais por meio de trabalhos colaborativos. O método pode ser aplicado em diferentes áreas do saber, e há prevalência de sua aplicação no Ensino Superior, com escassas pesquisas aplicadas ao Ensino Fundamental. Sobre o papel do professor, alguns autores defendem o docente como mediador importante na aprendizagem e outros lhe conferem um papel de coadjuvante. A ABP contribui para o desenvolvimento do pensamento crítico e reflexivo, promovendo uma aprendizagem significativa. Apresenta-se uma pesquisa qualitativa do tipo colaborativa, com o objetivo de identificar as mudanças na relação ensino e aprendizagem com a aplicação da ABP na disciplina de História do Ensino Fundamental de uma escola pública do interior de São Paulo. Os resultados mostraram que a ABP permite maior aproximação do professor com os alunos, potencializando a aprendizagem.

LINHAS DE VOO DE UM BEBÊ SURDO: EMARANHADOS E AGÊNCIAS NOS PROCESSOS DE SUBJETIVAÇÃO E EDUCAÇÃO
Authors: LINS HELOÍSA A. MATOS
Published: May 2021

RESUMO: O artigo apresenta reflexões a partir de uma pesquisa cartográfica com um bebê surdo, colocando em questão a dimensão antropocêntrica da compreensão dos agenciamentos, onde se destaca também o papel dos fluxos materiais no processo de subjetivação dos bebês, através das contribuições do pensamento pós-humanista. Para tanto, Ingold, Deleuze, Guattari, Moss e Braidotti foram os principais interlocutores, destacando-se os emaranhados/ malhas e as intra-ações como constructos epistemológicos nesses contextos. A partir desse giro conceitual, também são discutidas as implicações para o campo pedagógico e para os Estudos da infância. Após refletir sobre os fluxos materiais do som e outros significados nesse processo, a pesquisa contextualiza e destaca o conceito de agência antropocêntrica, contra argumentando pela consideração da força das coisas / materiais nos processos subjetivos de bebês e crianças que passam a ser compreendidos a partir de novas referências híbridas, enredadas, como seres "vazados" pelo (em direção ao) mundo. Tal dimensão analítica pode reverberar na área educacional, a partir da sensibilidade pedagógica que, para se constituir e projetar, assume a imprevisibilidade e os múltiplos/emaranhados/complexos aspectos envolvidos nas agências infantis.
TRABALHO DOCENTE COM VIDEOAULAS EM EaD: DIFICULDADES DE PROFESSORES E DESAFIOS PARA A FORMAÇÃO E A PROFISSÃO DOCENTE
Authors: PENTEADO REGINA ZANELLA , COSTA BELARMINO CESAR GUIMARÃES DA
Published: May 2021

RESUMO: O artigo aborda os impactos das tecnologias digitais no trabalho docente e na relação com a ideia de docência como profissão considerando a videoaula como principal recurso educacional da docência na EaD e no ensino remoto. O objetivo é analisar teses e dissertações brasileiras que abordam questões, problemas e dificuldades enfrentados por professores no processo de produção de videoaulas para EaD. Uma revisão no BR-CAPES-BTD resultou em 11 dissertações que mostram distanciamentos entre a formação docente e a realidade de trabalho em EaD. As precariedades envolvem aspectos de linguagens (audiovisual e do professor - expressividade) e de socialização docente. Delas decorrem efeitos prejudicantes nas dimensões: pessoalidade do professor (sentimentos negativos, desconfortos, sofrimentos e mal-estar); desenvolvimento profissional docente e impacto social da docência (qualidade do ensino). Em tempos de educação digital, a produção de videoaulas é uma prática constituinte do trabalho docente que requer ser analisada e compreendida. O artigo mostra uma faceta dessa realidade da docência que tensiona a profissionalização do ensino e traz novos desafios para a formação de professores.

Narrativas compartilhadas na formação da professora iniciante
Authors: Simas Vanessa França
Published: May 2021

RESUMO O objetivo do presente artigo é revelar como ocorreu o processo de interlocução entre uma professora iniciante e um grupo de profissionais da educação, através de narrativas que a primeira escrevia sobre a própria prática pedagógica e enviava a esse grupo. A professora iniciante era também a pesquisadora que investigava como se constituía docente nessa fase da carreira. As narrativas sobre a própria prática e a narrativa da pesquisa eram ampliadas pelas narrativas dos sujeitos com quem a professora convivia no cotidiano escolar e no grupo de interlocutoras, por isso a pesquisa tem um cunho auto/hetero/biográfico. A metodologia narrativa de pesquisa em educação, em diálogo com os aportes da filosofia bakhtiniana, foi a utilizada para compreender esse processo interlocutivo. A materialidade a ser interpretada foi composta pelas narrativas da professora e do grupo de interlocutoras. Revelou-se que os movimentos de narrar e de compartilhar esses escritos potencializaram excedentes de visão de si, das relações e dos acontecimentos, já que ela se colocava num outro espaço e num outro tempo no momento da escrita, construindo outras compreensões para o já vivido, bem como memórias de futuro relativas à docência. Os atos de narrar a própria prática e compartilhar essas narrativas se mostraram potentes no processo formativo de professoras iniciantes na carreira docente.
Broad and fine-scale threats on threatened Brazilian freshwater fish: variability across hydrographic regions and taxonomic groups
Authors: Santana Murilo Luiz e Castro , Carvalho Fernando Rogério , Teresa Fabrício Barreto
Published: May 2021

Abstract: Anthropogenic environmental changes are the main cause of species extinction during the Holocene. Species have been exposed to major source of threats, such as habitat loss and fragmentation, pollution, introduced species, and harvesting, many of which are derived from specific anthropogenic activities, such as urbanization, agriculture, and damming (i.e. fine-scale threats). However, the importance of these threats on the species conservation status in a given region depends on the type of impacts they are exposed to and the susceptibility of species to these impacts. In this study, we used a database of threatened Brazilian freshwater fish species to test whether the major source of threats and the specific anthropogenic impacts to species vary across hydrographic regions and taxonomic groups. Our results showed that habitat loss is a ubiquitous major threat jeopardizing the conservation status of the Brazilian fish species. However, different fine-scale threats mediate this process across hydrographic regions and taxonomic groups. The combination of impacts from agriculture, deforestation, and urbanization affects most of the threatened species in the basins of the Northeast, South, and Southeast, including the species of the most threatened order, the Cyprinodontiformes. Damming is the main human activity affecting threatened species of Siluriformes, Characiformes, Gymnotiformes, and Cichliformes, especially in northern basins (Amazon and Tocantins-Araguaia). Therefore, we found that specific fine-scale threats influencing threatened species vary across hydrographic regions and taxonomic groups, probably due to geographic variability in the incidence of human activities and differential niche requirements and vulnerability of species to these activities.

ABSTRACT: Colonoscopy is a minimally invasive technique used to assess the large intestine through direct inspection of the intestinal mucosa. When associated with histopathological examination of fragments collected from the intestine, the definitive diagnosis can be obtained. This retrospective study evaluated colonoscopy and histopathological exams of the large intestine and ileum of dogs with gastrointestinal disorders admitted at the Veterinary Hospital of the Federal University of Minas Gerais (UFMG) and the Veterinary Hospital São Francisco de Assis to determine the frequency of injuries, their distribution in the intestinal segments, and the relationship of the findings observed in these two analyzes. The colonoscopy and histopathological findings of the case series were described using absolute and relative frequencies, as well as nature and intensity classification of the findings. Cohen’s Kappa coefficient was obtained to assess the concordance of nature and intensity classifications between colonoscopy and histopathology, and its 95% confidence interval constructed. The analyses were performed using the Software SAS University Edition. It was observed a moderate agreement between the classification of the nature of the findings by endoscopy and histopathology (Kappa coefficient = 0.39, CI = 0.20-0.59). This can also be observed when assessing the frequency of similar diagnoses between the methods, since only 39 (72.22%) were consistent, i.e., 15 (22.78%) diagnoses differed depending on the nature of the finding, which could have a great influence on the final diagnosis if histopathology was disregarded. For the intensity of the injuries, little agreement was observed between the methods (Kappa coefficient = 0.1243, C = -0.05-0.30). This was even more evident in the frequency of similar diagnoses in terms of intensity, of which 20 (37.04%) were similar and 34 (62.96%) were different. Inflammatory affections are the most frequently observed alterations in the large intestine and ileum of dogs. The most common finding that reveals inflammatory changes is the lymphoplasmacytic infiltrate. As for the proliferative and neoplastic lesions, adenomatous polyps and lymphoma were common. The most affected sites of the large intestine were the descending colon and the rectum. Findings such as edema and reddening of the mucosa were frequent by macroscopy. Although the changes observed by colonoscopy and histopathology may not be similar, these techniques are complementary, which makes biopsies mandatory for a diagnostic conclusion.

ABSTRACT: The objective of this study was to verify the applicability of B-mode ultrasonography, ARFI elastography and CEUS in the diagnosis of chronic kidney disease and its Stages in dogs. 24 healthy dogs and 28 with CKD were included. In B-mode, the echogenicity, echotexture and cortico-medullary ratio of the kidneys were verified. By elastography, the shear-wave velocity of the cortical (SWVcort) and medullary (SWVmed) regions were determined and tissue deformity was evaluated. Wash-in, wash-out and peak enhancement (TPic) of the contrast in the renal parenchyma were calculated and homogeneity, presence of filling gaps and distinction of filling phases were evaluated by CEUS. Changes in echogenicity, echotexture and cortico-medullary ratio were observed only in sick patients. There was an increase in SWVcort in CKD, with a cutoff point >2.91m/s. Healthy kidneys were non-deformable and 25% had changes in gray scales. There was an increase in wash-in and TPic, changes in filling characteristics, filling failures and difficulty in distinguishing between the Stages in CEUS in CKD. It was found that dogs with CKD 2, 3 and 4 had greater SWVcort and wash-in values than CKD 1. Elastographic and CEUS changes were observed in dogs with CKD, demonstrating the applicability of ultrasonographic techniques in their diagnosis.

Published: May 2021

ABSTRACT: Fipronil was registered in Uruguay in 1997, and, since then, it has been used for the control of Haematobia irritans irritans and Rhipicephalus microplus. The susceptibility of H. irritants to this drug has not been evaluated. Therefore, the goal of the present study was to evaluate the resistance of H. irritans to fipronil. Additionally, a survey was carried out with the farmers to evaluate the use of fipronil for H. irritans control in the ranches where the flies came from. For the bioassays, 31 field populations of H. irritans were exposed to 10 concentrations of fipronil (3.2-16.0μg.cm2), and their LC50 values were calculated using probit analysis. A bioassay was performed with horn flies from the susceptible colony maintained at the USDA-ARS Knipling-Bushland U.S. Livestock Insects Research Laboratory for comparison and calculation of resistance ratios (RRs). All 31 field populations surveyed in the study were susceptible to fipronil, with resistance ratios ranging from <0.5 to 2.2. Four populations with RRs >1 did not differ significantly from the susceptible strain. A single population showed an RR >2.2. Overall, the survey shows that fipronil was mostly used for R. microplus control, and in only three ranches, which were free of R. microplus, was fipronil used for horn fly control. Seventeen farmers did not use fipronil at all in the last three years. It is concluded that, in Uruguay, field populations of horn flies remain susceptible to fipronil.

ABSTRACT: Objective: To compare social characteristics, risk behaviors, and sexually transmitted infections among travestis and transsexual women. Methodology: A cross-sectional study was carried out in three cities in Goiás, Central Brazil. Trans women were interviewed on sociodemographic characteristics, discrimination, prejudice, sexual behavior, illicit drugs, and previous testing for HIV and syphilis between April 2018 and August 2019. Results: A total of 166 travestis and 249 transsexual women were investigated. Although sexual, physical, and verbal violence were common to both groups, sexual behavior, use of illicit drugs, prison, and previous positive HIV and syphilis testing were more frequent among travestis than in transsexual women. Conclusion: The present findings confirm that Brazilian travestis are at greater risk for sexually transmitted infections (STI), indicating that health services should take this imbalance into account in terms of health intervention proportions.

Published: May 2021

RESUMO: Objetivo: Avaliar a associação entre a coexistência de comportamentos de risco (CR) e o contexto familiar em adolescentes brasileiros. Métodos: Estudo transversal com 101.534 estudantes do 9º ano do ensino fundamental na Pesquisa Nacional de Saúde do Escolar 2015. A coexistência de CR foi estimada pelo somatório da presença de comportamento sedentário, baixo consumo de frutas e consumo regular de álcool e tabaco. A prevalência foi avaliada usando o diagrama de Venn e a análise multivariada por meio da regressão logística ordinal de chances parciais. Resultados: 8,8% dos adolescentes não apresentaram CR; 34,5% tinham um; 42,7% tinham dois; e 14,1%, três ou quatro. As combinações mais prevalentes foram entre comportamento sedentário e baixo consumo de frutas (33,8%); e comportamento sedentário com baixo consumo de frutas e consumo regular de álcool (9,5%). Tiveram maior chance de coexistência aqueles que tinham mães com maiores escolaridades em todos os modelos, não morar com os pais [0, 1 e 2 vs. 3: (odds ratio - OR = 1,21; intervalo de confiança de 95% - IC95% 1,07 - 1,37)], ter pais que às vezes, nunca ou raramente entendiam seus problemas e preocupações [0, 1 e 2 vs. 3: (OR = 1,62; IC95% 1,49 - 1,76)] e acompanhavam o dever de casa [0, 1 e 2 vs. 3: (OR = 1,77; IC95% 1,62 - 1,93)]; e realizar refeições com os pais ou responsáveis < 4 dias/semana para os três modelos. Conclusão: Os CR relacionados à saúde tendem a se agrupar entre os adolescentes brasileiros e estão associados a características do contexto familiar. Esses achados apontam para a necessidade de ações de promoção de saúde com foco na simultaneidade, e não de forma isolada.
Facile/LigFerv: Hot Water in Three Seconds, Thirty Years of Entrepreneurial Process

Published: May 2021

ABSTRACT This teaching case aims to discuss an entrepreneurial process involving the trajectory of an innovative product over thirty years until culminating in a significant event in the change of the company’s business model in the midst of the crisis triggered by the pandemic of the new coronavirus. The case offers opportunities for discussing theories related to the entrepreneurial process - causation and effectuation logic. In addition, in the course of the recent trajectory, in which the company is selected for an acceleration program, a possible change in the business model emerges. Reported from the perspective of the founder, but also supported by materials from secondary sources, the case presents the trajectory of Facile. The teaching strategy consists in enabling the student to learn, first, about the entrepreneur’s decision-making and action, emulating transitions between the causation and effectuation logic throughout the case to explain such behavior. Subsequently, the case inquires about possible alternatives for changing the business model for the company after the acceleration program, in which students will be able to identify more suitable alternatives in the face of both the company’s skills and, not least, the pandemic that changed the behavior of customers and entrepreneurs.

ABSTRACT This teaching case aims to discuss an entrepreneurial process involving the trajectory of an innovative product over thirty years until culminating in a significant event in the change of the company’s business model in the midst of the crisis triggered by the pandemic of the new coronavirus. The case offers opportunities for discussing theories related to the entrepreneurial process - causation and effectuation logic. In addition, in the course of the recent trajectory, in which the company is selected for an acceleration program, a possible change in the business model emerges. Reported from the perspective of the founder, but also supported by materials from secondary sources, the case presents the trajectory of Facile. The teaching strategy consists in enabling the student to learn, first, about the entrepreneur’s decision-making and action, emulating transitions between the causation and effectuation logic throughout the case to explain such behavior. Subsequently, the case inquires about possible alternatives for changing the business model for the company after the acceleration program, in which students will be able to identify more suitable alternatives in the face of both the company’s skills and, not least, the pandemic that changed the behavior of customers and entrepreneurs.

Published: May 2021

ABSTRACT This teaching case aims to understand how incremental cost analysis can be applied in decision-making. The case portrays a fishing company in the segment that suffered a disruption in demand from the international market as a result of the COVID-19 pandemic. Its managers, who already acted to mitigate previous financial problems, now need to decide how to dispose of fish production during the pandemic. The case encourages the development of analytical competence on the impact of a rupture in demand, the identification of relevant costs for decision-making from an income statement, and managerial decision-making based on incremental cost analyzes. This case, based on interviews and estimated accounting data, was designed for undergraduate and graduate courses focused on costs in the areas of Business and Accounting.
Magalu Has It: Social, Political, and Market Strategies during COVID-19

ABSTRACT This teaching case presents the strategic positioning of the Magazine Luiza group (Magalu), represented by the director of institutional relations José Ribeiro and Luiza Helena Trajano, chairman of the Board of Directors, before and during COVID-19. The case’s objective is to promote a reflection on the business strategies adopted in times of crisis. Since the beginning of the COVID-19 pandemic in Brazil, Luiza and Magalu have engaged in discussions and practiced a series of strategic actions for the benefit of the group’s employees, small- and medium-sized companies, and those most affected by the pandemic. A few months after the first case, the instability was still perceived, it was still present, the number of infected and deaths rose and little was known about when the daily life would return to ‘normal.’ Many questions persisted about Magalu’s next steps. Thus, it was necessary to discuss how the group should position itself to ensure performance and reputation. The proposal is to make students put themselves in the place of José Ribeiro, director of institutional relations and the urgent affairs commission of Magalu, in order to encourage a debate about the market and non-market strategies that could be implemented.

Published: May 2021

ABSTRACT This case describes the process of changing Chianca Softwares’ face-to-face work regime to the home office during government decrees caused by the new coronavirus pandemic. Chianca Softwares, a family company, which has been a player in the technology market in the state of Paraíba since 2003, went through a process of change in its governance model in 2012, and due to the improvements in its processes, it was awarded the Prêmio Média e Pequenas Empresas (MPE) of Sebrae PB in 2016. Given its adaptability, it faced the coronavirus crisis differently, overcame difficulties, and needed to reinvent itself to survive the ‘new normal.’ In this context, the case aims to lead students to reflect on the home office implementation process in Chianca, to identify the benefits and challenges of this teleworking regime and to think about ways to mitigate these challenges and create tools and practices to mobilize, integrate, and engage people in remote work. Thus, after restructuring its entire team to the new model of work in the home office, students are led to reflect on the dilemma that Chianca managers face due to the release of their face-to-face activities: stay in the home office regime or return to original patterns.

Published: May 2021

ABSTRACT This teaching case aims to understand the challenges between opening distribution channels and new products. The report involves a small Brazilian chocolate factory. It presents the structuring, production processes, brand concept, formation of sales prices, and the choice of distribution channels in COVID-19 times. The company faced challenges in the market for presenting products with low adherence to distribution channels, high costs and price, and an inadequate brand positioning, resulting in low sales. After repositioning itself with a new brand and price concept, the case raises the dilemma: What is the best distribution channel during the crisis period caused by COVID-19 for the newly restructured company? The pedagogical objectives are focused on the analysis of alternatives in the choice of distribution channels, considering the implementation challenges, the transaction costs for products at an early stage, and the scenario of uncertainties resulting from the pandemic, as well as the application of sales channel concepts and distribution. The case can be applied in undergraduate and MBA courses in the management area and is recommended to encourage students to reflect on the structure and challenges of implementing small entrepreneurs’ distribution channels.

ABSTRACT The case reports the trajectory of a telemedicine platform in Brazil. Conexa, a company that already operated with a telemedicine B2B model, took advantage of the regulatory change during the coronavirus pandemic (COVID-19) and launched Docpass, a B2C platform. The pandemic not only brought about a change in legislation, but also provided a context that reduced cultural barriers to the adoption of such a service for both doctors and patients. The case is recommended for Strategy and Innovation disciplines, more specifically in sessions dedicated to business models based on platforms, when the following learning objectives are worked on: (a) diagnosis of COVID-19 effects in a telemedicine business by comparing before, during, and after the pandemic; (b) understanding the network effects present on the platforms and their reflections in terms of value; (c) understanding the competitive dynamics in a platform ecosystem.
