Explorando a lacuna Darwiniana em Fabaceae (Leguminosae) na Bacia dos Rios Tocantins-Araguaia
(Universidade Federal de Goiás, 2026-03-10) Suzigan, Nina Machado; Pinto, Rafael Barbosa; Diniz-Filho, José Alexandre Felizola; http://lattes.cnpq.br/0706396442417351; Rangel, Thiago Fernando Lopes Valle de Britto; Antunes, Lorena Lana Camelo; Soares, Thannya Nascimento; Tessarolo, Geiziane
This study assessed the phylogenetic shortfall of legumes in the Tocantins-Araguaia Basin using the Phylogenetic Diversity Deficit (PDd) quantified at the species level (PDdSp) and the grid-cell level (PDdL). After data consolidation and taxonomic validation, the final checklist comprised 1224 species. PDdSp showed strong dependence on phylogenetic insertion: 59.6% (n = 729) of species required insertion into the reference phylogeny, yielding clustered positive values (median = 0.0028; IQR = 0.0016–0.0040; maximum = 0.0193) and marked concentration in a few megadiverse genera. Spatially, PDdL was highly heterogeneous when derived from point occurrences (median = 0.444; range = 0-1), with extreme values associated with low-richness cells, but became more stable when derived from distribution polygons (median = 0.342; IQR = 0.321–0.390). Genetic data availability in NCBI was broad yet uneven: 82.2% of species had at least one record (total of 158 745 entries), 17.8% lacked sequences, and among species with data the median was 6 records, with extreme concentration in a few taxa. Phylogenetic hurdle models indicated that the probability of PDdSp = 0 increases strongly with the number of genomic DNA sequences and with scientific output, whereas the magnitude of positive PDdSp was not explained by the covariates (being dominated by insertion rules). For PDdL, point-based models showed that cells composed of better-studied species and, under median aggregation, with greater genomic DNA availability tend to exhibit lower deficits; in polygon-based models, spatial dependence was dominant and additional effects were small. Overall, the phylogenetic deficit is substantial, lineage structured, and aligned with gradients of information accumulation. These results identify taxa and areas where deficits are concentrated and provide guidance to prioritize sampling, sequencing, and data curation, reducing phylogenetic incompleteness and strengthening ecological and conservation inferences in the basin.
Desenvolvimento do preceptor para o ensino da comunicação de más notícias na residência médica: uma pesquisa-ação
(Universidade Federal de Goiás, 2026-02-19) Silva, Ricardo Borges da; Pereira, Edna Regina Silva; http://lattes.cnpq.br/4503589425013098; Pereira , Edna Regina Silva; Rocha, Bárbara Souza; Amaral, Eliana Martonaro; Queiroz, Maria Goretti; Oliveira, Cacilda Pedrosa de
Breaking bad news (BBN) is an essential clinical competence in medical practice; however, it remains historically fragmented and poorly systematized within medical residency training. This study aimed to implement a Faculty Development Program for Preceptors (PDDP) focused on teaching BBN and to analyze the training needs and experiences of participating preceptors. This qualitative study adopted an action research design and was conducted at a federal university hospital in Brazil. The research was organized into four stages: diagnostic phase, planning, implementation of the FDPP, and evaluation. Two focus groups were conducted: Focus Group 1 (FG1) during the diagnostic phase and Focus Group 2 (FG2) during the evaluation phase. The intervention consisted of a 20-hour face-to-face course delivered during protected time and involved preceptors from clinical specialty residency programs. FG1 revealed one main category - teaching communication skills - and three secondary categories influencing the teaching and practice of BBN: generational dynamics, mental health, and cultural aspects. The findings indicate that teaching BBN extends beyond technical proficiency, requiring emotional, ethical, and pedagogical competencies. The FDPP was structured using active learning methodologies, including simulation with standardized patients, structured debriefing, team-based learning, and reflective portfolios, integrated with the pedagogical use of an adapted Professionalism Mini-Evaluation Exercise (P-MEX). Preceptors identified recurring challenges, such as difficulty providing formative feedback, the emotional impact of BBN, conflicts related to religious beliefs, and the role of family members in shared decision-making. Analysis of FG2 indicated a positive reaction to the intervention and assimilation of new concepts through reflective learning, fostering the development of communicative and pedagogical competencies and contributing to the initial construction of preceptors’ professional teaching identity, particularly through recognition of their role as communication role models. This study concludes that teaching BBN is not limited to transmitting protocols or scripts but involves sustaining an ethical, humane, and relational stance. Practical implications include the need to institutionalize longitudinal faculty development programs, integrate communication training with mental health support, adopt active methodologies, and strengthen the reflective dimension of faculty education. Study limitations include its single-center design, lack of longitudinal follow-up, and absence of multiprofessional team participation. Future research should explore the validation of national instruments specific to BBN, longitudinal evaluation of educational and clinical impact, and investigations into the interface between BBN, burnout, spirituality, and culture.
Avaliação do escore de condição corporal por imagens digitais em fêmeas suínas gestantes
(Universidade Federal de Goiás, 2026-03-09) Cunha, Ana Caroline Rodrigues da; Ventura, Ricardo Vieira; https://lattes.cnpq.br/0956712532589198; Almeida, Vivian Vezzoni de; https://lattes.cnpq.br/4160526490591013; Carmo, Adriana Santana do; https://lattes.cnpq.br/0782572407995106; CARMO, ADRIANA SANTANA DO; GARBOSSA, CESAR AUGUSTO POSPISSIL; SCHULTZ, ERICA BEATRIZ; COSTA JUNIOR, JOAO BATISTA GONÇALVES; SILVA, SERGIO FRANCISCO DA
Monitoring body condition is one of the most critical practices in the production management and nutritional monitoring of female swine, performed at strategic moments to improve the reproductive performance rates of the herd population. However, these visual evaluations and/or caliper measurements are prone to inconsistencies due to personal perceptions of the ideal phenotype. Continuous evaluation of phenotypic characteristics under morphological assessment allows for nutritional adjustments that optimize sow productivity. This process, which requires time, labor, and involves stressful manual interventions for the animals, can be automated through the collection of 2D digital images of the animals. To minimize the bias of subjective BCS assessment, this study developed and evaluated a deep learning-based approach using pre-trained neural networks for automated classification in pregnant sows and gilts. Aiming to identify the architecture that provides the ideal balance between generalization capability and precision, 190 PIC® Camborough® females were used, with 760 2D digital images captured using a Samsung Galaxy A34 smartphone, considering 4 collections from 190 females during the gestation period, as follows: 567 images for the Ideal class, 140 images for the Under class and 53 images for the Over class. The grid search technique was used to execute 60 experiments, varying the hyperparameters, in addition to obtaining globally optimal combinations for the machine hyperparameters through the adjustment of the PSO algorithm. Furthermore, 80% of the data were used for training, within this set, 20% were used for validation (467 images for training and 116 images for validation) and subsequently, 20% of the dataset (177 images) were used for testing. All convolutional neural networks and hybrid architectures were evaluated using the weighted global F1-Score, the F1-Score per class, and accuracy on the test dataset, as well as the loss function. After the experimental configurations and the correction adjustment between hyperparameters, performance metric results for the convolutional neural networks were obtained on the test set. The experiment for the ResNet50 architecture demonstrated the greatest robustness and consistency, achieving sensitivity for both minority classes, with an accuracy of 70% and an F1-Score per class of 25.4%, 23.5% and 81.5% for Under, Over, and Ideal, respectively, in addition to a weighted F1-Score of 66.5%. The experiments conducted in this study demonstrated that the direct application of transfer learning to body condition in females presents challenges that go beyond the choice of neural network architecture, such as dataset quality. It was further observed that, despite hyperparameter optimization and the application of class weights, the final model encountered difficulties in discriminating against minority classes for all hybrid architectures. The results of this study suggest that the primary limitation lies in the feature extraction stage, likely due to the visual anatomical similarity between the BCS classes.
A CASERNA NÃO ENSINA NA SOMBRA: a formação policial militar como racionalidade institucional explícita
(Universidade Federal de Goiás, 2026-03-20) Ramos, Weden Carlos; Machado, Maria Izabel; https://lattes.cnpq.br/5727858375243141; Carvalho, Thais Regina de; Bordin, Marcelo; Machado , Maria Izabel
This dissertation analyzes the training process within the Military Police of Espírito Santo (PMES), examining how an explicit institutional rationality organizes practices, rites, and regimes of conduct that produce subjectivities and strain the incorporation of Human Rights guidelines. It problematizes the use of the "hidden curriculum" category to explain the mismatch between the official discourse of citizenship-oriented training and the daily experience of the barracks. It argues that the decisive formative core does not operate through concealment, but rather through the publicization and repeated legitimation of a "pedagogy of form" that precedes content. A qualitative approach with an autoethonographic orientation is adopted, articulating the researcher's situated experience as an officer and instructor, the documentary analysis of regulations, manuals, and internal norms, and semi-structured interviews with soldiers and sergeants. The findings indicate that training acts as a technology of power that reorganizes body and time, produces a rupture with civilian references, and consolidates adherence to the military ethos through physical exhaustion, peer surveillance, exposure, and disciplinary moralization—progressively narrowing the field of the "sayable" and turning self-censorship into an institutional competence. It is argued that Human Rights discourse tends to enter as a prescription and is translated into a regime of adaptation to command, generating occasional shifts but frequently being reabsorbed as a language of compliance, evaluation, and proof. The study concludes that the limits of citizenship-oriented training stem less from curricular gaps and more from an internal moral economy that rewards toughness, virility, and silence; therefore, effective changes require reconfiguring the regimes of visibility, speech, and recognition that structure the barracks.
Ciclos eleitorais e ideologia partidária: a dinâmica das despesas públicas municipais no Brasil à luz da teoria dos ciclos político-orçamentários
(Universidade Federal de Goiás, 2026-02-26) Faria, Paulo Alexandre Oliveira de; Silva, Gilberto Crispim da; http://lattes.cnpq.br/9259035373490100; Silva, Gilberto Crispim da; Machado, Lucio de Souza; Pereira, Clesia Camilo
The present dissertation has the general objective of analyzing the influence of the political–budget cycle and political–partisan ideology on the allocation pattern of expenditures of Brazilian local governments, in light of the Theory of Political Budget Cycles (TPBC). To achieve this objective, the study was structured into two scientific articles. The first article, entitled “Analysis of electoral cycles in the dynamics of municipal expenditures in Brazil in light of the Theory of Political–Budget Cycles”, investigated the dynamics of committed expenditures in Brazilian municipalities in electoral years, in light of the TPBC with Institutional Constraints. The sample comprised committed expenditures by function for 5,513 Brazilian municipalities over the period 1995 to 2021. The second article, entitled “Ideological–partisan influence on the allocation of municipal expenditures in Brazil in light of the Theory of Political Budget Cycles”, assessed the influence of the ideological orientation of political parties on municipal fiscal management. For this purpose, the sample consisted of committed expenditures by function for 5,562 municipalities, from 2001 to 2021. In both studies, a panel regression model with fixed effects and robust standard errors, clustered by municipal ID, was employed, complemented by GMM robustness checks (Arellano–Bond, 1991; Anderson–Hsiao, 1982). Data were obtained from the databases of Ipeadata, the National Treasury, the Superior Electoral Court, the Brazilian Institute of Economics of FGV (IBRE-FGV), and the Federation of Industries of the State of Rio de Janeiro (FIRJAN). The empirical results of the first study do not indicate the presence of statistically consistent PBC patterns in Brazilian municipalities specifically in electoral years. However, this evidence does not imply a rejection of the TPBC (Drazen & Eslava, 2006, 2010), since, in non-electoral periods, a systematic prioritization of expenditures with greater political visibility was observed. This finding suggests that the Brazilian institutional framework, characterized by a high degree of fiscal and regulatory oversight, operates as a disciplining mechanism on public managers’ behavior in electoral years, constraining explicit practices of budget manipulation. Additionally, the results indicate that municipal managers internalize and adapt to the prevailing institutional constraints during electoral periods. By contrast, in the three-year period preceding elections, a greater intensity in the recomposition of the budget structure was observed, with resources directed toward categories of higher political salience. This dynamic unfolds in an environment of relative decision-making flexibility, as evidenced by the magnitude of the coefficients associated with the lnDempTotal variable, which points to greater discretion in the allocation of public resources throughout the term-of-office cycle. At the theoretical level, these findings reinforce the robustness of the TPBC (Drazen & Eslava, 2010), while partially challenging the assumptions of the opportunistic model with rational expectations (Rogoff, 1990) by highlighting the relevance of expenditure composition, rather than only its aggregate level. In the second study, by incorporating the partisan ideological dimension, the results expand the explanatory scope of the TPBC. It was verified that ideological orientation influences the allocation of municipal expenditures in Brazil, albeit heterogeneously and without a standardized pattern across regions, in line with previous evidence in the national literature. This finding suggests that Brazilian multipartyism favors pragmatic fiscal management strategies, reducing the sharpness of traditional ideological distinctions, consistent with the notion of a “crisis of ideologies”. In this context, indications of strategic reorganization of expenditure composition over terms of office are observed, with resources directed toward items of greater visibility, thereby providing empirical support for the study’s central hypothesis
