Artigo Científico A dual character theory of law(2024) GUILHERME DA FRANCA COUTO FERNANDES DE ALMEIDAOne persistent question in jurisprudence relates to the role of morality in the concept of law. For instance, consider the question of whether unjust statutes are laws. Legal positivists say that they’re laws in every relevant sense, while natural lawyers say that they’re not. This article considers a different answer inspired by recent findings in experimental philosophy: there is one relevant sense in which unjust statutes are laws, but also a different relevant sense in which they aren’t. After considering the ways in which this alternative differs from some of the mainstream theories in general jurisprudence, the article argues that it provides more elegant solutions to two problems that have puzzled legal philosophers in the past: the paradox of customary international law and the shifts in legal discourse over history.Artigo Científico Epistemology Goes AI: A Study of GPT-3?s Capacity to Generate Consistent and Coherent Ordered Sets of Propositions on a Single-Input-Multiple-Outputs Basis(2024) Araújo, Marcelo de; GUILHERME DA FRANCA COUTO FERNANDES DE ALMEIDA; Nunes, José LuizThe more we rely on digital assistants, online search engines, and AI systems to revise our system of beliefs and increase our body of knowledge, the less we are able to resort to some independent criterion, unrelated to further digital tools, in order to asses the epistemic reliability of the outputs delivered by them. This raises some important questions to epistemology in general and pressing questions to applied to epistemology in particular. In this paper, we propose an experimental method for the assessment of GPT-3’s capacity to generate consistent and coherent sets of outputs. When several outputs to one and the same input are very repetitive they tend to be consistent with each other, that is they do not contradict each other. But consistency does not make the set of outputs as a whole more informative than the outputs considered individually. We argue that the less informative a set of outputs is, the less coherent it is. We establish a conceptual distinction between consistency and coherence in the light of what some epistemologists refer to as a coherence theories of truth and justification. While much attention has been given to GPT-3’s capacity to produce internally coherent individual outputs, we argue, instead, that more attention should be given to its capacity to produce consistent and coherent outputs generated on a single-input-multiple-outputs basis.Artigo Científico Lawful, but not Really: The Dual Character of the Concept of Law(2024) Flanagan, Brian; GUILHERME DA FRANCA COUTO FERNANDES DE ALMEIDADisagreement on law’s relationship to morality has long been driven by disagreement about our ordinary concept. Until recently, however, there had been no systematic investigation of lay intuitions. In this paper, we advance this nascent effort. Across two studies (N = 697), our findings reveal that most people consider law to be more than a matter of political circumstance alone. Contrary to the expectations of most contemporary philosophers, morality (both substantive and procedural) emerges as a key influence on judgments of legal validity: many people say that conduct prohibited by immoral statutes is not truly illegal, and that immoral conduct which was never explicitly prohibited is truly illegal. This suggests that people often treat law as a dual character concept that, like the concepts of scientist or of artist, features autonomous concrete and abstract dimensions.Artigo Científico Exploring the psychology of LLMs’ moral and legal reasoning(2024) GUILHERME DA FRANCA COUTO FERNANDES DE ALMEIDA; Nunes, José Luiz; Engelmann, Neele; Wiegmann, Alex; Araújo, Marcelo deLarge language models (LLMs) exhibit expert-level performance in tasks across a wide range of different domains. Ethical issues raised by LLMs and the need to align future versions makes it important to know how state of the art models reason about moral and legal issues. In this paper, we employ the methods of experimental psychology to probe into this question. We replicate eight studies from the experimental literature with instances of Google's Gemini Pro, Anthropic's Claude 2.1, OpenAI's GPT-4, and Meta's Llama 2 Chat 70b. We find that alignment with human responses shifts from one experiment to another, and that models differ amongst themselves as to their overall alignment, with GPT-4 taking a clear lead over all other models we tested. Nonetheless, even when LLM-generated responses are highly correlated to human responses, there are still systematic differences, with a tendency for models to exaggerate effects that are present among humans, in part by reducing variance. This recommends caution with regards to proposals of replacing human participants with current state-of-the-art LLMs in psychological research and highlights the need for further research about the distinctive aspects of machine psychologyArtigo Científico Bolsonaro's botched coup attempt exposed political fault lines in the Brazilian democracy(2024) LUCAS MARTINS NOVAES; DIEGO WERNECK ARGUELHESThis paper analyzes the institutional legacy of the Bolsonaro government on Brazilian democracy, with effects on 2023 and beyond. Focusing on the rebalance of the power of the executive branch vis-a-vis other powers, we argue that Bolsonaro’s botched coup attempt exposed the limitations of existing regime safeguards. First, the activation of the military brought the shadow of raw power to the political table. Second, the increased leverage Congress now exercises over the executive has ambiguous effects on its willingness to check authoritarian overreaches from the President. Finally, we consider how the conflict between the past President and the Supreme Court has made the court more politicized, potentially affecting its public standing and making it a more likely target for future attacks within the political system. We suggest that, while democracy has resisted, it is not immune to backsliding. We briefly discuss how this reshuffling will shape the scenario for Lula’s presidency and the Worker's Party in the coming years.- Digital Twin data architecture for Product-Service Systems(2024) Durão, Luiz Fernando C.S.; Zancul, Eduardo; Schützer, KlausThe digital representation of physical products by Digital Twins has been increasingly perceived as a relevant enabler for Product-Service Systems (PSS). Digital Twins concentrate product data that can be applied to generate insights and thus support value-added services. However, the literature on the intersection between Digital Twin and PSS has only recently started to receive more attention. There are still research gaps related to the required data and systems integration. In this context, this research aims to propose a Digital Twin data architecture to support Product-Service Systems operation. A Design Science Research (DSR) approach is applied, and the proposed architecture has been implemented and tested. Assessment results indicated that the proposed Digital Twin architecture fulfills the four requirements established from the literature: 1) facilitate and support the service offering; 2) acquire and transmit field operation and customer data; 3) integrate design and manufacturing data; 4) guarantee real-time monitoring, data integration, and data fidelity. The presented results provide an original contribution to the research area and can serve as a reference for applying Digital Twin to support PSS in practice.
- 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 deThe 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.
- 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 ARTESPurpose – 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. RicardoThe 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.
