  • Do epistemicídio a epistemologias do aparecimento: mulheres negras no Sistema de Justiça e nas Ciências Criminais
    (2020) ALLYNE ANDRADE E SILVA
    O artigo critica o tratamento dado as mulheres negras, utilizando como exemplo o duplo lugar ocupado pelas mulheres negras no sistema de justiça e nas Ciências Criminais: visíveis como alvos preferenciais do encarceramento feminino e invisíveis como vítimas da violência contra a mulher e feminicida. O objetivo é realizar uma crítica acerca das produções que, embora críticas ao sistema penal e cientes da sua seletividade, apenas utilizam essas mulheres como números para retratar os problemas do sistema de justiça. Tais análises, de maneira geral, são incapazes de observar as mulheres negras enquanto intérpretes desse mesmo sistema e da sua própria realidade, de trazer raça como elemento central das causas dessas violências. Por fim, proponho que interseccionalidade seja utilizada como uma epistemologia do aparecimento das mulheres negras e como uma perspectiva crítica antirracista, que confere às estas a primazia epistêmica de interpretação de suas próprias realidades.
  • The status of the human gene catalogue
    (2023) PAULO DE PAIVA ROSA AMARAL; Carbonell-Sala, Silvia; De La Vega, Francisco M.; Faial, Tiago; Frankish, Adam; Gingeras, Thomas; Guigo, Roderic; Harrow, Jennifer L.; Hatzigeorgiou, Artemis G.; Johnson, Rory; Murphy, Terence D.; Pertea, Mihaela; Pruitt, Kim D.; Pujar, Shashikant; Takahashi, Hazuki; Ulitsky, Igor; Varabyou, Ales; Wells, Christine A.; Yandell, Mark; Carninci, Piero; Salzberg, Steven L.
    Scientists have been trying to identify every gene in the human genome since the initial draft was published in 2001. In the years since, much progress has been made in identifying protein-coding genes, currently estimated to number fewer than 20,000, with an ever-expanding number of distinct protein-coding isoforms. Here we review the status of the human gene catalogue and the efforts to complete it in recent years. Beside the ongoing annotation of protein-coding genes, their isoforms and pseudogenes, the invention of high-throughput RNA sequencing and other technological breakthroughs have led to a rapid growth in the number of reported non-coding RNA genes. For most of these non-coding RNAs, the functional relevance is currently unclear; we look at recent advances that offer paths forward to identifying their functions and towards eventually completing the human gene catalogue. Finally, we examine the need for a universal annotation standard that includes all medically significant genes and maintains their relationships with different reference genomes for the use of the human gene catalogue in clinical settings.
  • Portabilidade e customização de um softcore RISC-V em FPGA
    (2023) Nagai, Diego Salviano; Dantas, Leandro Poloni; Silva, Marcones Cleber Brito da; Canno, Luis Carlos; Sousa, Fernando Simplicio de
    As FPGAs são dispositivos lógicos capazes de implementar qualquer tipo de circuito digital, esta característica torna este dispositivo uma excelente ferramenta para o estudo e desenvolvimento em diversas áreas da eletrônica e da computação. Entretanto há algumas características inerentes a estes dispositivos que podem inviabilizar a sua utilização. O custo dos kits de desenvolvimento para FPGAs é maior que aquele observado nos kits para microcontroladores, além disso a complexidade dos ambientes de desenvolvimento e a incompatibilidade entre si também desfavorecem o uso desta ferramenta. Para evitar o custo de aquisição de um novo kit e também poupar o tempo gasto no aprendizado de um novo ambiente de desenvolvimento a cada novo projeto, torna-se imprescindível adotar um processo de portabilidade. A portabilidade consiste em migrar um projeto desenvolvido em uma plataforma ou dispositivo para outra, mantendo as mesmas funcionalidades. Neste contexto, este trabalho teve como objetivo explorar a portabilidade de um softcore RISC-V em FPGA. Isso envolveu, primeiramente, a revisão de código e simulação do projeto a ser portado e, em seguida, a adequação do projeto à nova plataforma na qual o sistema foi embarcado. Utilizando o kit de desenvolvimento DE10-Lite e o ambiente Intel Quartus Prime Lite Edition, as funcionalidades originais do projeto foram mantidas após a portabilidade, e novos recursos foram adicionados. Dentre eles, chaves e displays de 7 segmentos como novos dispositivos de entrada/saída.
  • As métricas de software em favor do desenvolvedor como ferramentas para a produtividade e a qualidade em soluções embarcadas
    (2023) Canno, Luis Carlos; Dantas, Leandro Poloni; Sousa, Fernando Simplicio de; Silva, Marcones Cleber Brito da
    Muitos profissionais da área de software concordam que um atributo importante dos sistemas embarcados é a qualidade, traduzida como a menor incidência de defeitos quanto possível. No entanto as empresas de desenvolvimento destes softwares precisam ao mesmo tempo aprimorar seus níveis de produtividade sem esquecer a qualidade do produto e uma forma efetiva e prática para medir esses aprimoramentos. Assim esta pesquisa tem por finalidade orientar as pessoas envolvidas no arcabouço do projeto, em especial os desenvolvedores de software no estabelecimento de metas para alcançar melhores padrões de qualidade e produtividade durante o processo de desenvolvimento do produto de sistemas embarcados que são implantados através de um processo exaustivo das análises de requisitos. Em especial aqueles ditos não funcionais, deste modo, estes sistemas precisam de um teste completo e processo de verificação e validação.
  • How Songs from Growing Up and Viewers’ Attachment Styles Affect Video Ads’ Effectiveness
    (2022) Lourenço, Carlos J. S.; GIULIANA ISABELLA; Verbeke, Willem; Vo, Khoi; Dimoka, Angelika; Bagozzi, Richard P.
    We propose that the positive effect of coming-of-age songs on ad effectiveness arises from a mediation process where the music-evoked interpersonal memories of growing up stored in the brain and their accompanying emotions inevitably play a role, but not so straightforwardly as previously suggested. Rather, their effects work through the heightened familiarity of and peaked preferences for coming-of-age songs. We also propose that these sequentially mediated effects are moderated by viewers' developmental attachment styles. We test and find support for these propositions in three multimethod studies with more than 1200 participants born between the 40s and the mid-70s and almost 60 popular songs released between the 60s and the 2010s. We discuss the implications of our findings, namely for age-segmented video ads, and suggest future research directions.
  • Joint Effects of Shared and Transformational Leadership on Performance in Street-Level Bureaucracies: Evidence from the Educational Sector
    (2022) Lagowska, Urszula; Sobral, Filipe; GUSTAVO MOREIRA TAVARES
    Recent theories of public administration emphasize the importance of leadership as shared property. This research focuses on the role of the interaction between vertical and shared leadership in promoting agency performance. Specifically, it examines the joint effects of shared leadership and transformational leadership on team empowerment and performance in public settings. Based on field study data collected from 74 street-level bureaucracies and 423 public servants in Brazil, we find evidence that vertical transformational leadership strengthens the direct relationship between shared leadership and team empowerment as well as the indirect relationship between shared leadership and school performance through team empowerment (a moderated-mediation model). The findings of this study suggest that greater attention should be paid to the dynamics of shared and vertical leadership structures to better understand their consequences for team pro cesses and outcomes in public settings.
  • What is women’s position in Brazil’s board interlocking network? An analysis covering the period from 1997 to 2015
    (2023) CHARLES KIRSCHBAUM; Barros, Thiago de Sousa
    Until very recently, the companies’ boards of directors have shown a strong male predominance, while controversial results regarding the insertion of women in these bodies have prevailed. Given this, this research aimed to investigate the evolution of women’s participation in the boards of directors of Brazilian companies listed on B3 and the position of these directors in the corporate board interlock network, between 1997 and 2015. To understand this phenomenon, the Social Network Analysis (SNA) methodology was adopted and several indicators were. The results indicate that women’s participations has increased top management positions of the Brazilian corporate environment and women have begun n to integrate the boards of directors, a scenario still far from the reality observed in developed countries. Nonetheless, by analyzing the corporate network connector , we have concluded that women reach high proximity, since they have a high degree of centrality in the network, but they also lack the potential for intermediation. Such results signal the need to increase gender diversity at the top level of companies, which could raise the quality of debate on boards of directors and improve levels of corporate governance.
  • Business Model Innovation for the Sustainable Development Goals
    (2022) Rosati, Francesco; VINICIUS PICANÇO RODRIGUES; Cosenz, Federico; Li-Ying, Jason
    Business model innovation can be a key driver to realizing the transformation needed to achieve the United Nations Sustainable Development Goals (SDGs). At the same time, the SDGs can support organizations as they identify and tackle opportunities for business model innovation. This study uses a constructive research method to build a managerial approach that supports business model innovation for the SDGs. The approach helps organizations assess their contribution to the SDGs, explore and prioritize SDG-oriented business opportunities and risks, and formulate business model innovation strategies accordingly. The proposed approach was developed through participatory action research conducted in collaboration with two companies operating in the medical and educational sectors and then applied to Ørsted, a multinational power company, which is strongly committed to a sustainability-driven business transformation and aspires to contribute strongly to SDG 7 (Affordable and clean energy) and SDG 13 (Climate action). The study furthers the academic and practical debate on business model innovation for sustainability by providing new academic and practical knowledge on how organizations can use the SDGs to stimulate business model innovations.
  • Sales compensation plan type and sales opportunity coverage: “Double-edged” sword effects on sales performance
    (2023) DANNY PIMENTEL CLARO; Plouffe, Christopher R.; Vieira, Valter Afonso
    Sales compensation plans affect salespeople's prospecting activity and sales opportunity coverage because they shape behavior in terms of how reps manage their territory and broader portfolio of customers. Drawing on goal-setting theory, the authors propose and test a theoretical framework which unearths a “double-edged” sword moderating effect whereby the number of pursued sales opportunities impacts the main effect of sales compensation plan type on resultant sales (performance). The reported empirical study examines salesperson data prior to and after the implementation of a new compensation plan. We then utilize the metaphor of the “double-edged” sword to further explicate the findings, whereby the volume of sales opportunities is found to moderate sales goal and quota achievement (i.e., amplifying the main effect). The research also finds that pursuit of too many sales opportunities can become overly burdensome, thereby overloading salespeople and reducing goal commitment and performance. Implications for both research and practice are discussed.
  • Not separate, but certainly unequal: the burdens and coping strategies of low-status street-level bureaucrats
    (2023) Lotta, Gabriela; Krieger, Morgana G. Martins; Cohen, Nissim; CHARLES KIRSCHBAUM
    The literature has usually regarded street-level bureaucrats (SLBs) as relatively privileged bureaucrats, neglecting an important sub-group of these civil servants: low-status SLBs. Even though they may be members of a team with other SLBs who have more status, they may suffer from intraorganizational inequality, meaning unequal access to resources and the requirement that they perform informal tasks associated with their unequal position in the organization. We examine the unique challenges low-status SLBs are often confronted with, and how they cope with them. Based on 94 interviews with community health workers in Brazil, we identify several types of burdens associated with their ambiguous tasks, as well as the strategies they use to cope with these burdens. The analyses suggest that the burdens and coping strategies are an important source of the inequality on the team. The paper discusses the importance of considering the diversity of roles occupied by SLBs and the inequalities within teams.

  • Access to fresh food in vulnerable urban areas: a classificatory study of slums and formal establishments in São Paulo
    (2024) ANDRÉ LUIS DE CASTRO MOURA DUARTE; VINICIUS PICANÇO RODRIGUES; Alves, Raquel Carolinne Freitas; Oliveira, Gustavo Magalhães de
    The environment significantly influences individuals’ food choices. Vulnerable urban areas, such as favelas, can have a decisive impact on discouraging the consumption of fresh, nutritionally rich foods. This issue is exacerbated by the urban infrastructure required to deliver fresh foods to these locations. Therefore, it is essential to understand the context of the favelas in the municipality of São Paulo in terms of the food environment and infrastructure to support the design of public policies that enhance the presence of minimally processed foods in these areas. We applied the k-means clustering method to two datasets: the food environment of favelas, characterized by food establishments, and the urban infrastructure of the favelas in the municipality of São Paulo. Of the city’s 1,701 favelas, only 271 have formally registered food establishments. Larger favelas with better urban infrastructure generally exhibited a food environment with greater access to fresh foods. The results suggest that investing in urban infrastructure can increase access to fresh foods in these areas. It is also necessary to consider local specificities to find effective solutions that increase the availability of minimally processed foods, thereby improving the population’s quality of life and health.
  • The benefits and barriers of additive manufacturing for circular economy: A framework proposal
    (2023) Tavares, Thais Moreira; Ganga, Gilberto Miller Devós; Godinho Filho, Moacir; VINICIUS PICANÇO RODRIGUES
    According to preliminary research, additive manufacturing (AM) is a promising technology for developing circular material flow. However, the impact of AM on the circular economy (CE) is unclear. To address this issue, this study proposes a framework that presents the benefits and barriers of AM for CE. This framework is valuable for generating a new path for AM production and restructuring the supply chain. This study uses a multi-method research approach to propose this framework. (i) Secondary qualitative data were used to find the best way to categorise the results; (ii) literature review was applied to understand how the phenomenon of AM adoption meets or does not meet CE requirements; and (iii) interviews with experts were conducted to evaluate the results. The findings help to systematically highlight the benefits and barriers of AM for the CE and provide a research agenda that identifies specific actions that AM stakeholders should take to align with the CE. The broader potential of AM as a beneficial technology for CE is contingent on overcoming the identified critical barriers, and the economic viability of circular AM activities. The findings could be relevant because they clearly show how AM technology brings companies and society closer to or farther from CE.
  • Repair as a circular strategy for increasing resource availability and health system resilience during a crisis
    (2023) Cobra, Raphael; Moroni, Iara Tonissi; VINICIUS PICANÇO RODRIGUES; Fradinho, Jorge M.S.
    Background Healthcare is a complex socio-technical system where nations regularly struggle with the misalignment between public needs and available resources. The advent of COVID-19 further exacerbated shortcomings, as evidenced by the global panic to find ventilators and beyond. However, the pandemic catalysed a successful Brazilian public-private voluntary partnership that united key industry players, industrial training centres and several volunteers, who, in the absence of a supportive government, could repair ventilators in record time, giving the health system means to succeed. Objectives Characterise how a voluntary public-private partnership came into existence and codify recommendations on how it effectively used repair as a circular strategy to increase ventilator availability and bolster health system resilience. Methods Case study using multiple data sources collected over 10 months, including national data, semi-structured interviews, daily reports, and internal communications. Sampling, research instruments, and subsequent qualitative data analysis and theory development grounded in repair strategy, resilience, and supply chain literature. Results A successful public-private voluntary partnership delivered 2,514 repaired ventilators, approximately 3% of the total ventilators in use in Brazil and impacting around 24,700 lives. Furthermore, effectively functioned as a first-responder bringing to hospitals approximately 500 repaired units as early as April 2020, surpassing the government's procurement and doing so just-in-time for Brazil's COVID 1st wave. More than 70 institutions and 700 professionals helped hospitals in 25 out of 27 Brazilian states. This case documents how the initiative persevered through adversity, including inadequate policies representing a widespread difficulty in enforcing the “right to repair”. Public interest summary In Brazil, automakers, the National Industrial Training Service and other organisations formed a voluntary and temporary alliance to repair broken ventilators that had accumulated in hospitals. This initiative took place at the beginning of the COVID-19 pandemic and returned 2,514 ventilators to hospitals, supporting patient care and partially alleviating the shortage of ventilators. This repair depended on the training of technical staff who had never worked with health equipment before. In addition to training, there was a need to share information and manuals, calibrate repaired equipment, procure spare parts, organise logistics and find funding, amongst other activities, meaning that it was a wide scale operation involving several organisations - both within and outside the health system. This research demonstrates the role of ventilator repair in making a health system more resilient in the event of a health emergency, and the urgent need to develop strategies to make repair an everyday commitment.
  • David vs Goliath: The challenges for plant-based meat companies competing with animal-based meat producers
    (2023) Reis, Germano Glufke; Villar, Eduardo Guedes; Ryynänen, Toni; VINICIUS PICANÇO RODRIGUES
    An extensive body of literature has recently discussed how the transition from animal-based meat to alternative sources of proteins could help to reduce the environmental impacts of livestock chains, such as greenhouse gas (GHG) emissions. Alternative proteins are broadly characterized as being made with ingredients that replace traditional protein sources and have a lower environmental impact, while the terms “meat analogs” and “meat substitutes” refer more specifically to alternative protein products that incorporate the nutritional and sensory characteristics of meat.
  • Assessing the performance of voluntary environmental agreements under high monitoring costs: Evidence from the Brazilian Amazon
    (2023) BRUNO VARELLA MIRANDA; Oliveira, Gustavo Magalhães de
    Voluntary environmental arrangements generally coexist with State-based and private rules, creating a property rights system that legitimizes certain behaviors. In a world of positive transaction costs, legitimacy ensues from imperfect monitoring activities, opening room for opportunism. In this paper, we discuss how the existence of multiple rules in a scenario of high monitoring costs affects the performance of an environmental policy. We discuss the case of deferred prosecution agreements (TAC, acronym in Portuguese), which are voluntary arrangements designed with the goal of incentivizing slaughterhouses to monitor the environmental practices of ranchers in the Brazilian Amazon. More specifically, we study how the signature of a TAC agreement affects deforestation rates in the Brazilian Amazônia Legal region at the municipality level. This paper adopts a difference-in-differences approach to analyze a sample of Brazilian municipalities between 2006 and 2017. Our results, which remain robust across alternative estimators and subsamples, show that the signature of a TAC agreement increases deforestation rates by 0.2 standard deviations. We argue that the signature of a TAC agreement, by creating an imperfect proxy for “good behavior” that enables both compliant and non-compliant organizations to access credit, may incentivize deforestation in the Brazilian Amazon.
  • Gestão dos prazos da dívida corporativa: um olhar para as empresas de capital aberto no Bras
    (2023) Santos, João Daniel Azevedo dos; ADRIANA BRUSCATO BORTOLUZZO; Gonçalves, Adalto Barbaceia
    Este estudo investiga a estrutura de vencimento da dívida de 275 empresas abertas não financeiras brasileiras de 2010 a 2019. Os resultados mostram que essas empresas não dispersam seus vencimentos de dívida na renovação, ao contrário do observado por Choi et al. (2018) para empresas dos Estados Unidos. Mesmo após o choque de rolagem da dívida depois da perda do grau de investimento da dívida soberana brasileira em 2015, essas empresas não aumentaram a dispersão de vencimentos. Ao utilizar a perda do grau de investimento do Brasil como um "experimento quase-natural" no modelo de choque de crédito, o presente estudo avalia a gestão da dívida corporativa. Os resultados indicam que as empresas brasileiras podem enfrentar consideráveis riscos de rolagem da dívida devido à concentração de vencimentos em faixas específicas durante futuros choques de crédito. O controle adequado das estruturas de financiamento é crucial para garantir que as empresas permaneçam resilientes e não precisem recusar investimentos lucrativos ou ativos de alta qualidade durante crises financeiras. Esta pesquisa tem implicações significativas para a prática corporativa e os riscos associados ao financiamento de projetos lucrativos, particularmente em países com mercados de capitais menos eficientes.
  • Opening the “black box” of food safety policy implementation: the efficiency-enhancing role of a private meso-institution
    (2023) Oliveira, Gustavo Magalhães de; BRUNO VARELLA MIRANDA; Saes, Maria Sylvia Macchione; Martino, Gaetano
    There is continuing interest in how rules created at the “institutional environment” level influence the perfor mance of food safety policies. The influence of institutional rules on the behavior of farms and firms may vary widely depending on how strongly incentives reach potential users. This article assesses how the creation of a private meso-institution (i.e., Conseleite) affects the implementation of food safety guidelines in the Brazilian dairy industry. We use a dataset that has laboratory analyses of milk from 18 out of the 27 Brazilian states over a period that goes from 2006 to 2014. We show that the creation of Conseleite has led to an increased effectiveness of implementation of the Normative Instruction 51, which sets indicators and basic parameters of milk quality in Brazil. Specifically, the creation of Conseleite in the Brazilian state of Mato Grosso do Sul led to a decrease in the low-quality index related to the bacterial contamination of milk. In turn, we find that Conseleite played a limited role in raising the values of the high-quality milk index. Our conclusions highlight the fundamental role of meso institutions in bridging the gap between the “institutional environment” level and the “governance” level. This study sheds light on a potential policy implementation path for other developing and emerging countries in the dairy industry, which is marked by frequent food safety scandals.
  • Entrepreneurship in times of economic stress: unraveling the U-shaped relationship between the internality of causal attributions and growth
    (2024) GUILHERME FOWLER DE AVILA MONTEIRO; RINALDO ARTES
    Purpose – This paper examines the relationship between entrepreneurs’ internality of causal attributions and firm growth during an economic crisis. We propose a U-shaped relationship between the two variables, arguing that the highest-growth entrepreneurs are those with either the highest or lowest levels of internal attribution (IA) during such periods.
  • The dark side of the boom: dutch disease, competition with China, and technological upgrading in colombian manufacturing
    (2024) Branstetter, Lee G.; Laverde-Cubillos, N. Ricardo
    The natural resource boom of the 2000s spurred growth in income and consumption in many commodity-exporting nations. However, this paper brings together a previously unused combination of data sets from Colombia to document evidence of a downside – the currency appreciation associated with this boom led to a significant and persistent decline in R&D spending and in investment in technological upgrading by Colombian manufacturing firms. Our empirical strategy exploits differences in firms' sales across products and export destinations to create firm-specific measures of exposure to exchange rate shocks both abroad and at home. We link these new measurements of exchange rate exposure with Colombian micro data on R&D investment and technology upgrading. The key finding is that real exchange rate appreciation drives significant reductions in both firm-level R&D investment and a measure of technology upgrading that includes expenditure on capital goods, technology licensing, worker training, and other expenditures related to the adoption of new technology. Even after key commodity prices dropped significantly in the mid-2010s, inducing a substantial and long-lasting Colombian currency depreciation, investments in R&D and technology upgrading remained at subdued levels. Our estimated effects suggest that the resource boom and associated appreciation had a significant and persistent negative effect on technological development of Colombian manufacturing firm, and these conclusions remain even after careful attempts to simultaneously control for rising competition with Chinese manufacturers, which also had a negative effect on Colombian firms' technology investments, and the effects of trade liberalization at home and abroad. Similarities between Colombia and other commodity-exporters suggest that the effects documented in this paper may be widespread.
