    Donateli, Cíntia Pereira; Campos, Fernando Celso de

    Resumo em Português:

    RESUMO As arboviroses têm se tornado uma preocupação constante para a saúde pública. O gerenciamento do grande volume de dados gerados pelo sistema de saúde faz-se necessário para compreender melhor a dinâmica das arboviroses e apoiar políticas públicas no enfrentamento dessas doenças. Assim, a visualização de dados torna-se um recurso promissor que permite disseminar tais informações e aumentar assim a sua visibilidade e utilização. Desenvolvemos um dashboard para sistematização e visualização de dados de vigilância das arboviroses urbanas transmitidas pelo Aedes (Dengue; Zika e Chikungunya) em Minas Gerais, Brasil, de modo a favorecer sua ampla disponibilidade, acessibilidade e relevância para a tomada de decisão em saúde orientada por dados. O dashboard desenvolvido conta com quatro painéis gerenciais sendo cada uma das arboviroses estudadas, exibidas em separado, e o quarto painel geral representa as três arboviroses unificadas. O dashboard ficou funcional e capaz de ser aplicado na gestão, apresentando informação útil e valiosa, de maneira visual e descomplicada, aos tomadores de decisão na área da saúde pública orientada por dados.

    ABSTRACT Arboviruses have become a constant concern for public health. The management of this large volume of data generated by the health system is necessary to better understand the dynamics of arboviruses, support public policies in the management of these diseases. Thus, data visualization becomes a promising resource that allows disseminating such information and thus increasing its visibility and use. We developed a dashboard for systematization and visualization of surveillance data on urban arboviruses transmitted by Aedes (Dengue; Zika and Chikungunya) in the state of Minas Gerais, Brazil, in order to favor its wide availability, accessibility and relevance for data-driven decision-making in health. The developed dashboard has four management panels, each of the studied arboviruses, displayed separately, and the fourth general panel represents the three unified arboviruses. The dashboard became functional and capable of being applied by public health management, presenting useful and valuable information, in a visual and uncomplicated way, to data-driven decision makers.

    Dias Júnior, José Jorge Lima; Silva, Anielson Barbosa da

    Resumo em Português:

    RESUMO Este artigo propõe uma escala de mensuração para a avaliação das competências adaptativas de profissionais que atuam em equipes de software no Brasil. A escala foi concebida à luz da teoria da adaptabilidade ( Pulakos et al., 2000 and ( Baard, Rench, & Kozlowsky, 2014) para atender as características de dinamicidade, complexidade e imprevisibilidade do contexto. A construção seguiu um processo rigoroso balizado pela teoria da mensuração ( Rossiter, 2010 ; Costa, 2011; Devellis, 2016), contemplando etapas qualitativas e quantitativas, o que incluiu entrevistas com 14 profissionais, validação de face e conteúdo por 21 especialistas, amostragem de limpeza com 233 estudantes, e uma segunda amostragem com 454 profissionais que atuam em organizações da área de tecnologia no Brasil para validação da escala. A partir de análise fatorial exploratória e confirmatória, obteve-se uma escala confiável e validada com 29 itens vinculados a sete dimensões: Resolução de problemas, Controle emocional, Autoaprendizagem, Busca por ajuda, Resiliência, Liderança para coordenação e Liderança para cooperação. A escala proposta pode contribuir para ampliar a compreensão sobre a atuação profissional em equipes de software.

    Resumo em Inglês:

    ABSTRACT This paper aims to propose a measurement scale for assessing the adaptive competencies of professionals who work in software teams in Brazil. The scale was developed based on adaptability theory ( Pulakos et al., 2000; Baard, Rench, & Kozlowsky, 2014) to address the characteristics of dynamicity, complexity and unpredictability of the context. The construction followed a rigorous process guided by the measurement theory ( Rossiter, 2010; Costa, 2011; Devellis, 2016), encompassing qualitative and quantitative stages, including interviews with 14 professionals, face and content validation by 21 experts, a cleaning sample with 233 students, and a second sample with 454 professionals who work in organizations in the technology industry from Brazil to validate the scale. Through exploratory and confirmatory factor analysis, a reliable and validated scale was obtained, consisting of 29 items linked to seven dimensions: Problem-solving, Emotional control, Self-learning, Seeking help, Resilience, Leadership for coordination and Leadership for cooperation. The proposed scale can contribute to enhancing the understanding of professional performance in software teams.

A framework is also proposed to organize these topics into two central lines, guiding future research and practice.
  • PANORAMA DA ARQUITETURA CORPORATIVA NA ADMINISTRAÇÃO PÚBLICA DO BRASIL Artigo

    Vilela-Cury, Luisa; Ramos, Karoll Haussler Carneiro; França, Joysse Vasconcelos; Montezano, Lana

    Resumo em Português:

    RESUMO Arquitetura corporativa (AC) é uma ferramenta mundialmente adotada por governos de alto desempenho em governança pública que viabiliza uma gestão da informação integrada. Este artigo investiga o desenvolvimento do Framework de Arquitetura Corporativa para Interoperabilidade no Apoio à Governança (FACIN) do Governo Federal do Brasil, analisando os fatores que justificam sua adoção e os benefícios esperados desta implantação. Foi realizada análise de conteúdo e triangulação acerca de documentos que subsidiaram a elaboração do FACIN e dos artefatos produzidos. Verificou-se que, apesar da AC oportunizar uma gestão mais racional e eficiente e promover governança, a introdução do modelo no Brasil ainda precisa superar barreiras gerenciais e políticas.

    Resumo em Inglês:

    ABSTRACT Corporate architecture (AC) is a tool adopted worldwide by high-performance governments in public governance that enables integrated information management. This article investigates the development of the Corporate Architecture Framework for Interoperability in Support of Governance (FACIN) of the Federal Government of Brazil, analyzing the factors that justify its adoption and the expected benefits of this implementation. Content analysis and triangulation were performed on documents that supported the elaboration of FACIN and the artifacts produced. It was found that, despite CA provides a more rational and efficient management and promotes the governance, the introduction of the model in Brazil still needs to overcome managerial and political barriers.
  • EVALUATION OF E-COMMERCE SYSTEMS: COMPARATIVE STUDY BEFORE AND DURING THE COVID-19 PANDEMIC IN BRAZIL Article

    Mendonça Júnior, Demétrio; Dallagnol, Mathäus Freitag; Martins, Vanessa Quadros; Freitag, Viviane Costa

    Resumo em Inglês:

    ABSTRACT The increasing use of e-commerce, stimulated by the period of social isolation given the pandemic of COVID-19, requires accompanying measures, among them, the evaluation of the success of the Information System (IS). A stream of research has been dedicated for over 30 years to evolving / adapting IS evaluation models. This investigation empirically tests the theoretical model of DeLone & McLean (2004); in two distinct periods, before (model 1) and during (model 2) the COVID-19 pandemic. A survey was conducted with 329 consumers of business to consumer e-commerce in Brazil. This research is quantitative and used structural equation modeling to analyze the data. The results showed that, before the pandemic, e-commerce users did not perceive value in the quality of the system's information while, during the pandemic, perceived this aspect as important. That is, they also started to recognize more value in the quality of the system during the pandemic. This was the result of the increased use of the e-commerce system during the period of social detachment. This quantitative study has some limitations. First, the survey was conducted twice, before and during the Covid-19 pandemic specific on the Brazilian e-commerce consumption context. Second, the sample size is limited. The study contributes academically by applying the model quantitatively in a Western context. Furthermore, it has strategic potential, as positive experiences in the IS lead the consumer to reuse it, generating revenue.
  • MASTER-PM: ADDRESSING REMOTE TEACHING CHALLENGES IN PROJECT MANAGEMENT THROUGH A SERIOUS GAME APPROACH Original Article

    Luna, Alexandre José Henrique de Oliveira; Silva, Adriano Ednaldo da; Lima, Fúlvia Fernanda de; Rocha, Lorena Brandão Oliveira

    Resumo em Inglês:

    ABSTRACT The Covid-19 pandemic provoked a reevaluation of teacher-student dynamics, prompting the adoption of innovative approaches to ensure student engagement, participation, academic performance, and retention. To effectively address the emerging challenges in this context, mixed methods research was conducted, anchored by the Design Science Research approach, where artifacts were developed, evaluated, and systematized in a collaborative serious game, MASTER-PM. The findings demonstrated the game’s positive impact on teamwork learning outcomes, and valuable student feedback facilitated iterative enhancements to the game and its support artifacts. This paper describes the MASTER-PM application in an undergraduate administration course at a Brazilian university and evaluates its viability and usefulness in project management education.
