Users’ trust in black-box machine learning algorithms Heitor Hoffman Nakashima, Daielly Mantovani, Celso Machado Junior Revista De Gestao, 2024 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 Daielly M. N. Mantovani, Kleber Rodrigues Santos, Thaisa Barcellos Pinheiro Nascimento, Celso Machado Jr. Handbook of Research on Solving Societal Challenges Through Sustainability Oriented Innovation, 2023 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.
Volatility of the COVID-19 vaccine hesitancy: sentiment analysis conducted in Brazil Celso Machado Júnior, Daielly Melina Nassif Mantovani, Luísa Veras de Sandes-Guimarães, Maria do Carmo Romeiro, Cristiane Jaciara Furlaneto, et al. Frontiers in Public Health, 2023 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 Degree of Contribution of Digital Transformation Technology on Company Sustainability Areas Ivanir Costa, Rosangela Riccotta, Paola Montini, Eduardo Stefani, Roberto de Souza Goes, et al. Sustainability Switzerland, 2022 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.

Digital sustainability: how information and communication technologies (ICTs) support sustainable development goals (SDGs) assessment in municipalities Daielly Melina Nassif Mantovani Ribeiro, Flavio Hourneaux Junior, Cristiana Lara Lara Cunha, Patricia Taeko Kaetsu, Patricia Fernanda Dionizio-Leite, et al. Digital Policy Regulation and Governance, 2021 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.
Analysis of the affinity of the principles of corporate governance to the ISO 14001 environmental management system standard Renata Carolina Grotta, Celso Machado Júnior, Maria Tereza Saraiva de Souza, Daielly Melina Nassif Mantovani Ribeiro, Roberto Bazanini Gestao E Producao, 2020 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.
