The students’ performance refers to the following ENEM knowledge areas: Languages, Codes and their Technologies, Natural Sciences and their Technologies and Mathematics and its Technologies. This study reviews the literature on the subject of financial education, describing it as a policy in teacher training with the aim of bringing it to schools and the school community. The main objective of this research is to estimate the causal effect, i.e. the performance of students on the ENEM in public schools in Paraíba, after they have been students of teachers qualified by the Specialization Course in Financial Education at UFPB. To achieve this goal, the econometric method Propensity Score Matching (PSM) was used, combined with matching techniques and control groups. The results were a significant improvement in the grades of public school students, generated by the lessons given by the course teachers. This contributed to disseminating knowledge about financial education to the school community Editor: Universidade Federal da Paraíba Tipo: Dissertação Thu, 31 Aug 2023 00:00:00 GMT https://repositorio.ufpb.br/jspui/handle/123456789/37359 2023-08-31T00:00:00Z https://repositorio.ufpb.br/jspui/handle/123456789/37169 Título: Modelagem matemática aplicada ao controle da invasão do peixe-leão (pterois volitans) Autor(es): Abrantes, Franklin Gonçalves de Orientador: Wyse, Ana Paula Pintado Abstract: In this study we intend to discuss the possible impacts caused by the lionfish, a marine fish of the Pterois volitans species, which over recent years has been responsible for causing damage to several native marine species, due to its high reproduction capacity, and for presenting a high predation rate. In this context, initially two mathematical models will be presented, one with density-dependent capture, and the other with constant capture, where situations will be demonstrated and compared to predict a possible scenario in which capture is greater than the growth of the species. In practical terms, a completely efficient capture method is not yet known, however there are studies that aim to develop a drone capable of capturing lionfish; The proposal is that this equipment will be able to capture 95% of lionfish in each delimited area, having the ability to distinguish lionfish from other species that may be present in the same location. Next, another study will be presented that describes the growth dynamics of the species considering the introduction of a variety of lionfish with YY chromosomes, called supermales, resulting from modified lionfish with inverted sex containing two Y chromosomes, with the objective interfering with the reproductive process of the species Pterois volitans. Scenarios obtained by numerical simulations will illustrate the dynamics of the models presented.

We be- gin by revisiting the classical theory of straight beams, founded on the Euler–Bernoulli and Timoshenko models, and derive the governing equations for deformation under distributed loading. These concepts are then extended to spatially curved beams, re- sulting in the derivation of constitutive and equilibrium equations that form a system of ordinary differential equations. To solve this problem, an abstract variational formu- lation founded on the Hellinger–Reissner principle is adopted, which enables general- ized displacements and internal forces to be treated as independent variables. In this context, the displacement and internal force fields are approximated by interpolation functions of the same polynomial degree, continuous for displacements and discon- tinuous for internal forces, thereby allowing greater flexibility in accurately capturing their internal variations. To guarantee the numerical stability of the approximations, least-squares residual terms are directly incorporated into the equilibrium equations at the element level, which prevents locking phenomena in the solution. Numerical results are presented to demonstrate the potential of the formulation.

The analysis, wich ocurred between 2017 and 2019, employs a methodology that combines the Differences-in-Differences (DiD) model with fixed effects and quantile regression, in order to estimate the effects of teacher training on students’ standardized scores across the four areas of evaluation, in addition to their performance on the writing section. The estimates indicate that teachers participating in the CEEF had a positive and statistically significant impact on their students’ academic performance, particularly in the areas of Mathematics and Human Sciences. Conversely, no relevant effects were observed in the other areas. The findings suggest that the inclusion of financial education topics in the school curriculum has the potential not only to enhance students’ financial literacy but also to foster the development of interdisciplinary competencies that are fundamental to academic achievement.
