Título: Empresa pedagógica como componente curricular no ensino médio: uma lógica empresarial na educação paraibana? Autor(es): Oliveira, Tailson Hugo Felix de Orientador: Albino, Ângela Cristina Alves Abstract: The research analyzes the guide of the discipline Empresa Pedagógica (EP), a curricular component of Upper Secondary and Technical Education in the state school system of Paraíba. It refers to the document titled “Empresa Pedagógica: basic training for work”, implemented in the Escolas Cidadãs Integrais and Escolas Cidadãs Técnicas of Paraíba. The aim of the research was to understand the conceptions of youth education that guide the Empresa Pedagógica component and its implications for the constitution of integral education in Upper Secondary School. The analysis uses theoretical frameworks from Christian Laval, Michael Apple, and Luiz Carlos de Freitas to discuss the expansion of neoliberal and entrepreneurial rationality in the Paraíba curriculum, situating EP within the context of educational reforms inspired by competency-based pedagogy. The research systematizes a state of knowledge that highlights the scarcity of studies on the component, but identifies works that point to the fragmentation of education, the centrality of the entrepreneur figure, and the prioritization of competencies aligned with the logic of employability, to the detriment of historical, political, and cultural dimensions. The results and discussion show that EP constitutes a set of policies that reorganize Upper Secondary Education to meet market demands and reinforce training based on human capital theory. By emphasizing entrepreneurial practices and management models, the discipline shifts the notion of integral education and redefines the future expectations of young people in Paraíba by directing them toward entrepreneurship.

Perfil de sensibilidade antimicrobiana de estirpes de Salmonella isoladas de répteis em cativeiro

Título: Perfil de sensibilidade antimicrobiana de estirpes de Salmonella isoladas de répteis em cativeiro Autor(es): Silva, Evilásio Vieira Orientador: Costa, Loise Araujo Abstract: The present study evaluated the antimicrobial susceptibility profile of Salmonella strains isolated from captive reptiles, including tortoises, snakes, and lizards, aiming to investigate differences among groups and identify potential public health risks. Reptiles were selected due to their relevance as companion animals and their ability to harbor Salmonella, a zoonotic pathogen of clinical importance. A total of 60 bacterial strains were analyzed and subjected to antimicrobial susceptibility testing against eight antimicrobials, including tetracycline, penicillins, fluoroquinolones, chloramphenicol, gentamicin, and fosfomycin. The results showed that resistance was predominantly observed for tetracycline, especially among strains isolated from snakes (55.6%) and tortoises (20.6%), while resistance to penicillins was detected exclusively in snake isolates. All strains were susceptible to chloramphenicol, gentamicin, and fosfomycin, and intermediate susceptibility profiles were observed only for ciprofloxacin, mainly among snake isolates. No strain was classified as multidrug-resistant, although some exhibited resistance to two or three antimicrobial classes. Differences in resistance profiles among reptile groups may be associated with diet, feeding habits, and previous exposure to antimicrobials in captivity. Overall, the findings indicate a low level of antimicrobial resistance; however, tetracycline and penicillins emerged as antimicrobials with a higher risk of resistance, highlighting the need for continuous monitoring of Salmonella in captive reptiles and the implementation of preventive measures to reduce the dissemination of resistant strains, contributing to public health and biosafety.

Morcegos nectarívoros e a polinização de pitayas (Selenicereus spp. Cactaceae) na Caatinga

Título: Morcegos nectarívoros e a polinização de pitayas (Selenicereus spp. Cactaceae) na Caatinga Autor(es): Sousa, Natália Araújo de Orientador: Araujo, Helder Farias Pereira de Abstract: Pollination is an ecosystem service of regulation, provision, and culture, responsible for producing fruits, seeds, and several other essential resources for humanity. Therefore, it is a service of great importance to the global economy. In recent years, economic interest in the dragon fruit species (Selenicereus spp.) has gained prominence due to its commercial value. Dragon fruits have floral features similar to those of native cacti pollinated by bats in the Caatinga, Brazilian semiarid region. Therefore, the present study aimed to evaluate the role of bats as effective pollinators of pitaya species in the Caatinga and whether bat diversity is influenced by the landscape. Natural pollination (control), manual pollination, and self-pollination (spontaneous and manual) treatments were performed on pitaya flowers. To assess pollination efficiency, the developed fruits were weighed and the number of seeds estimated. To test the efficiency of nocturnal and diurnal pollination, the flowers were exposed at different times. Finally, to assess the influence of the landscape on chiropteran diversity, mist nets were installed in two distinct locations (preserved vs. deforested) to identify species richness and abundance in the regions. The results indicate that the heaviest fruits were produced by manual cross-pollination in the species S. undatus and S. monacanthus, while S. costaricensis produced larger fruits through manual self-pollination. Furthermore, the number of seeds showed a positive correlation with increased fruit weight. Comparing pollination across different periods indicated that nocturnal pollination produces heavier fruits than diurnal pollination. Bat diversity was higher in the preserved area. Therefore, pitaya plantations become more efficient when formed by more than one pitaya species, producing better-developed fruits. Pollination efficiency can be observed by the number of seeds in the fruit, directly influencing fruit size and weight. Bats are the most efficient pollinators of dragon fruits, although bees can also pollinate these species. Finally, the level of landscape conservation influences bat diversity and, consequently, the pollination services realized by these animals. Editor: Universidade Federal da Paraíba Tipo: TCC

Número de cloroplastos como indicador estável para inferência de ploidia em portulaca spp.

Título: Número de cloroplastos como indicador estável para inferência de ploidia em portulaca spp. Autor(es): Belo, Viviane de Oliveira Orientador: Rêgo, Mailson Monteiro do Abstract: The success of breeding programs for ornamental plants such as purslanes (Portulaca spp.) is closely linked to the correct identification of ploidy levels. Polyploidization is a technique that generates new genetic combinations and phenotypic variations, making it useful in the improvement of Portulaca spp. due to their ornamental, medicinal, and nutritional value. This study aimed to determine the ploidy level of Portulaca spp. accessions by counting the number of chloroplasts per guard cell, providing support for breeding programs of the species. Leaf samples from 15 genotypes cultivated in a greenhouse were collected and analyzed under an optical microscope (40×). Three stomata from each of five random fields of the leaf were analyzed, and the data were subjected to ANOVA, the Scott–Knott mean test, and Tocher clustering. The observed means varied widely, from 4.93 to 24.65 chloroplasts per guard cell, indicating the presence of different ploidy levels, ranging from diploids to hexaploids. Analysis of variance confirmed significant differences among genotypes (p < 0.001). Tocher clustering classified the accessions into four distinct groups and revealed high genetic divergence between the most contrasting accessions (PU0010 with 24.65 chloroplasts and PU001 with 4.93). Broad- sense heritability was high (98.56%), indicating strong genetic control of the trait. The results confirm that chloroplast counting is an efficient primary tool with high selective accuracy (99.3%), useful for selecting genotypes and guiding crosses for the subsequent development of promising hybrids with desirable characteristics such as vigor, resistance, and ornamental value.
