    Cities in dust: percursos etnográficos da subcultura gótica em Goiânia (GO)
    (Universidade Federal de Goiás, 2026-08-09) Xavier, Helena Borges; Lemos , Gardênia de Souza Furtado; Lemos, Gardênia de Souza Furtado; Morais, Mariana dos Santos
    This study investigates the Gothic phenomenon as a contemporary urban subculture in Goiânia (GO), analyzing the psychosocial dynamics of identity construction, belonging, and resistance among its members within a conservative and commercialized dominant culture. Grounded in Cultural Studies and Critical Social Psychology, the research adopts an ethnographically inspired qualitative approach, combining literature review, participant observation (highlighting the 9th Gothic Encounter of Goiânia), and semi-structured interviews with members of the local scene. Drawing on the theoretical frameworks of Stuart Hall, Dick Hebdige, Antônio da Costa Ciampa, and Bader Sawaia, it discusses how the constituent elements of the "Goth universe" — style, post-punk music, body, and the aesthetics of excess — operate as tools for semiotic subversion and symbolic dispute against capitalist normalization. The results demonstrate that affiliation with the subculture drives a process of identity-metamorphosis toward a post-conventional and emancipatory stance, allowing individuals to reframe the ethical-political suffering caused by exclusion and perverse inclusion. The study concludes that the Gothic scene in Goiânia consolidates itself as a strategic space for affectivity and collectivity, transfiguring the stigma of the "stranger" and experiences of melancholy into the power of action and a dignified survival within the urban territory

    Shared information and the limits of firm performance
    (2026) Souza, Thiago Cavalcante de
    This paper develops a microfounded model in which integrating decisions through a shared signal improves local inference but weakens the diversification of decision errors inside the firm. Shared information lowers posterior variance at the decision level while raising the covariance of errors across decisions, generating conditional and potentially non-monotonic effects on aggregate firm performance. Digital integration provides the motivating application, but the mechanism is more general: changing the informational structure of the firm changes the extent to which errors diversify across choices. The model delivers an interior optimum and a structural interpretation for heterogeneous productivity effects and persistent partial adoption.

    Missions without hierarchy? The coordination paradox in mission-oriented policies in fragmented states
    (2026) Souza, Thiago Cavalcante de
    This article investigates why high levels of strategic directionality are not sufficient to ensure the effective implementation of mission-oriented innovation policies. Based on a conceptual and historical-institutional approach, grounded in evolutionary economics and the public governance literature, the study proposes a bidimensional framework that distinguishes strategic directionality and hierarchical coordination capacity as central analytical dimensions. Drawing on comparative qualitative evidence from Brazil, India, and South Africa, mobilized as analytical laboratories,the article identifies the regime of‘missions without hierarchy,’ in which strategic ambition coexists with low intra-state coordination capacity, resulting in implementation fragmentation. The main contribution lies in repositioning coordination as an explanatory variable—rather than a presupposition—of mission-oriented policies, offering an analytical instrument to understand the gap between orientation and execution. The article also outlines implications for the institutional design of industrial policies in contexts of state fragmentation.

    Direcionalidade em missões de transição energética sob restrições de orçamento impositivo
    (2025) Souza, Thiago Cavalcante de
    This article develops a theoretical model of fiscal directionalism in missionoriented policies applied to the energy transition. It argues that the transformative capacity of the state depends not only on the scale of green spending but also on the geometric coherence of the policy mix over time. By modeling budget execution as a vector subject to compositional dispersion, the paper shows that mandatory budget regimes may increase directional fragmentation, reducing strategic alignment even under expanding resources. Applied to the Brazilian case and to Mission 5 of the NIB, the model reveals a paradox: higher spending may coexist with a reduced capacity to stabilize dominant technological trajectories.

    Efeitos dinâmicos da desagregação tarifária em mercados oligopolistas: evidências da regulação da cobrança de bagagem no setor aéreo brasileiro
    (2026) Souza, Thiago Cavalcante de; Mendes, Daniel Morais
    This article estimates the causal effect of the authorization to charge for checked baggage, introduced in Brazil in 2017, on domestic airfares between 2012 and 2023. A difference- in- -differences model combined with a dynamic event-study design is employed, using the logarithm of the average fare per kilometer flown as the dependent variable, which enhances international comparability and controls for route-length heterogeneity. The models include structural, operational, and macroeconomic controls, as well as airport and time fixed effects, with two-way clustered standard errors. The results indicate an initial competitive shock, with a 5% to 7% reduction in Brazilian fares in the short run, consistent with price unbundling adjustments. However, these effects do not persist: tariffs gradually recomposed in the medium run and, in the long run, increased by about 3% to 4%, suggesting the internalization of ancillary revenues and pricing strategies aligned with the sector’s oligopolistic structure. Robustness tests confirm the consistency of the findings, indicating that the policy only temporarily affected price levels in the Brazilian aviation market.
