  • Users’ trust in black-box machine learning algorithms
    Heitor Hoffman Nakashima, Daielly Mantovani, and Celso Machado Junior
    Emerald
    PurposeThis paper aims to investigate whether professional data analysts’ trust of black-box systems is increased by explainability artifacts.Design/methodology/approachThe study was developed in two phases. First a black-box prediction model was estimated using artificial neural networks, and local explainability artifacts were estimated using local interpretable model-agnostic explanations (LIME) algorithms. In the second phase, the model and explainability outcomes were presented to a sample of data analysts from the financial market and their trust of the models was measured. Finally, interviews were conducted in order to understand their perceptions regarding black-box models.FindingsThe data suggest that users’ trust of black-box systems is high and explainability artifacts do not influence this behavior. The interviews reveal that the nature and complexity of the problem a black-box model addresses influences the users’ perceptions, trust being reduced in situations that represent a threat (e.g. autonomous cars). Concerns about the models’ ethics were also mentioned by the interviewees.Research limitations/implicationsThe study considered a small sample of professional analysts from the financial market, which traditionally employs data analysis techniques for credit and risk analysis. Research with personnel in other sectors might reveal different perceptions.Originality/valueOther studies regarding trust in black-box models and explainability artifacts have focused on ordinary users, with little or no knowledge of data analysis. The present research focuses on expert users, which provides a different perspective and shows that, for them, trust is related to the quality of data and the nature of the problem being solved, as well as the practical consequences. Explanation of the algorithm mechanics itself is not significantly relevant.

  • Engaging people on e-participation through social media interactions

    The chapter aims to analyze how social media engages citizens in issues related to municipal management in Brazilian capital cities (27 cities). For that, Twitter data was collected, and descriptive analysis, text mining, and social network analysis were carried out. Results show the most frequent interactions regarded sharing posts, replies, and reactions were less frequent. Text mining suggested behavior on Twitter is related on the hot news, so discussions tend to be superficial; network analysis showed mayor accounts have more connections with users than the cities' official accounts, which suggests a necessity for personification on the conversation. Interactions are both centralized (started by the city) and decentralized (start by the citizen), but consist merely of information transmission and opinion sharing, and more complex kinds of participation, such as co-creation and decision-making were not observed. These findings show the potential of social media communication for public management and give insights on how to develop a successful policy to participate in social media.

    BackgroundVaccine hesitancy is a phenomenon that can interfere with the expansion of vaccination coverage and is positioned as one of the top 10 global health threats. Previous studies have explored factors that affect vaccine hesitancy, how it behaves in different locations, and the profile of individuals in which it is most present. However, few studies have analyzed the volatility of vaccine hesitancy.ObjectiveIdentify the volatility of vaccine hesitancy manifested in social media.MethodsTwitter’s academic application programming interface was used to retrieve all tweets in Brazilian Portuguese mentioning the COVID-19 vaccine in 3 months (October 2020, June 2021, and October 2021), retrieving 1,048,576 tweets. A sentiment analysis was performed using the Orange software with the lexicon Multilingual sentiment in Portuguese.ResultsThe feelings associated with vaccine hesitancy were volatile within 1 month, as well as throughout the vaccination process, being positioned as a resilient phenomenon. The themes that nurture vaccine hesitancy change dynamically and swiftly and are often associated with other topics that are also affecting society.ConclusionPeople that manifest the vaccine hesitancy present arguments that vary in a short period of time, what demand that government strategies to mitigate vaccine hesitancy effects be agile and counteract the expressed fear, by presenting scientific arguments.

    The impact of new digital technologies creates challenges for the digital transformation process in company sustainability areas. The purpose of this study was to determine the degree of contribution of digital-transformation-enabling technologies to company sustainability areas of three pulp and paper manufacturing companies in Brazil and relate it to the UN Sustainable Development Goals (SDGs). Through a systematic literature review based on the PRISMA method, we sought to assess the key concepts of sustainability and the implementation of digital transformation (DT) through its enabling digital technologies. A field study was conducted in three Brazilian pulp and paper companies to assess the degree of contribution. They are leading companies in the paper and cellulose industry in Brazil. The results obtained indicate that the companies in this sample are still in a growth process regarding the use of digital technologies in their sustainability areas. Only one digital technology, cloud computing, appears relevant in one of the companies studied, which differs from the theoretical framework presented by the literature. To achieve the SDGs goals, countries, especially emerging ones, need to develop their technologies and their business and improve the results that relate to sustainability. The research method applied in this study can be replicated to other companies where the impact of digital transformation technologies on company sustainability is critical.

  • The development of cities supported by communication and information technologies

    Purpose This paper aims to discuss the role of information and communication technologies (ICTs) in the effective assessment of the sustainable development goals (SDGs) related to smart and sustainable city initiatives. Design/methodology/approach The study is based on a systematic review of the literature within the Web of Science and Scopus databases, comprising the studies about ICTs related to smart and sustainable city initiatives and sustainable assessment. Findings The main results point out that there are several different ways of assessing SDGs performance related to ICTs use in smart and sustainable city initiatives. However, the effectiveness of these assessments can be questioned. The intensive use of technology understood as the core of smart and sustainable cities does not imply an improvement in sustainability unless these technologies are strategically addressed to underpin those objectives. Moreover, not all SDGs have considered the use of ICTs in their targets. Research limitations/implications The scope of the study is limited to “how” the information is used and managed, rather than analysing the sustainable performance itself. As a limitation, the findings and conclusions do not consider other sources of studies, such as grey literature. Practical implications This study suggests some requirements for providing better and more reliable sustainable assessment, making smart and sustainable city initiatives more correlated with the SDGs. Social implications By acknowledging the difficulties associated with SDGs assessment, concerning the municipal level, the study offers valuable insights into the effectiveness of public policies and public management. Besides, the findings shed some light on if and how the use of ICTs can effectively enhance sustainable development issues. Originality/value This study offers valuable contributions to the literature by providing a collection of insights regarding how the ICTs may genuinely lead to a sound assessment of sustainable development, especially regarding the SDGs.

    Abstract The purpose of this research is to analyze the adherence of the NBR ISO 14001 standard to the Brazilian Institute of Corporate Governance Code of Best Corporate Governance Practices. The perspective established in the research interprets the existence of synergy between management supported by the Environmental Management Systems standard and the Code of Best Corporate Governance Practices. The research analyzed the contents of 177 environmental audit reports, performed by a certification company, which involved a set of 139 companies certified by NBR ISO 14001. It then related the requirements of the environmental management system with the elements present in the IBGC code. It identified the adherence to several requirements in common between the two systems analyzed, thus indicating the adequacy of establishing synergy in actions, and in the information held by both, providing benefits to the organization. Environmental auditing data indicate that companies have more difficult-to-handle items related to operational control, emergency preparedness and assessment of compliance with legal and other requirements. This is important information in the context of corporate governance, since it indicates potential risks that must be eliminated in order to guarantee the perenniality of the organization.

  • Market as religion: The dynamics of business network in megachurches
    Roberto Bazanini and Celso Junior
    Fucape Business School
    Contemporaneously, in market view, the market of symbolic goods of religion is characterized by the pluralism of options that the postmodern individual has to join religious institutions. In this scenerie, it establishes a situation of fierce rivalry for the achievement of competitive advantage. The according exploratory and qualitative research aimed at analyzing the marketing strategies developed by the IURD leaders with their stakeholders in the Solomon’s Temple. The results show that in the competitive market of symbolic goods of religion, the magnitude and sumptuousness of megatemples construct a brand image that places the theological concerns of a future life or of salvation in the background, prioritizing practical solutions to everyday problems .The contribution of the research is to explain how the neopentescostal churches reinterpret traditional values of religiosity, by accepting with naturalness what had been rejected by traditional Protestantism and, thus, to consolidate and at the same time to legitimize the new dynamics of the religions that they act with the logic of the market.

    This paper focuses on the social and environmental innovations of Brazilian companies, rather than on merely economic innovations. These innovations are discussed within the context of sustainability. Data were collected via a qualitative and descriptive study from the annual Guia Exame de Sustentabilidade magazine (2014 Edition). The magazine stated that 228 companies responded to the questionnaire. Of these, 61 companies stood out in Brazil for their policies and practices in sustainability and had their results published. The social innovations were geared towards meeting the needs of the surrounding communities. Environmental innovations appeared in greater numbers, connoting a higher stage of attention and interest from Brazilian companies. Environmental innovations were intended to evolve or improve processes and products and to reduce the consumption of resources.

    ABSTRACT Objective To verify if there is an analogy between the indicators of the Global Reporting Initiative adopted by hospitals in the private healthcare system. Methods Documentary research supported by reports that are electronically available on the website of the companies surveyed. Results The organizations surveyed had a significant adherence of their economic, social and environmental indicators of the model proposed by the Global Reporting Initiative, showing an analogous field of common indicators between them. Conclusion There is similarity between the indicators adopted by companies, but one of the hospitals analyzed had a greater number of converging indicators to Global Reporting Initiative.

    FapUNIFESP (SciELO)
    Na fase inicial da interação fornecedor-cliente, o grande desafio é a obtenção de um grau mínimo de confiança, suficiente para superar a barreira da ausência de conhecimento mútuo. Assim, o trabalho se volta para a discussão das formas de atuação sobre o comportamento dos agentes, tendo como foco o "aprender a cooperar". O objetivo é avaliar o efeito dos mecanismos formais de controle para a geração de um ambiente favorável à emergência da confiança. É um estudo explanatório que utiliza o estudo de caso como estratégia de levantamento e análise de dados. O caso aborda em profundidade a fase inicial do processo de interação entre uma empresa produtora de eletrodomésticos e panelas e seus fornecedores. O estudo não confirmou integralmente a proposição central, colocada com base na literatura, de que, na fase inicial da interação cliente-fornecedor, a formalização das relações, por meio da introdução de mecanismos de controle e coordenação, abre espaço à emergência da confiança e à troca de informações entre os agentes.
