Codeverse: Hacking Worlds, an educational digital RPG developed in this work and based on the Revised Bloom’s Taxonomy, is designed to teach introductory programming content and provide an alternative way to reinforce foundational programmingconcepts.Theresearchwascarriedoutinseveralstages,includingaliteraturereview, a focus group with teachers to gather requirements, the creation of the Game Design Document, game development, the construction of a didactic sequence, and classroom implementation with students in the Technical High School in Informatics program. Data collection and analysis involved triangulation of pre- and post-tests, observations recorded in a logbook, and a questionnaire, providing an integrated view of learning, usability, and engagement. The results show learning gains with a normalized Hake gain of 0.40, along with evidence of increased autonomy, logical reasoning, and student engagement in the proposed activities. The findings indicate that educational digital games based on learning theories or taxonomies, such as Bloom’s Taxonomy, can enhance teaching and learning experiences in Computer Science. The evidence supports the conclusion that Codeverse has effectively integrated the cognitive, affective, and procedural dimensions of learning, making it a playful and accessible pedagogical resource.

In this context, Multicultural and Intercultural Science Education is configured as an approach that values different knowledge and identities, challenging homogeneous views of science and culture. In light of these assumptions, we developed a WebQuest as a theoretical methodological resource aimed at undergraduate students in Pedagogy, with the objective of articulating theory and practice in the mobilization of multicultural and intercultural principles in science teaching in the early years. The investigation, with a qualitative approach, focused on the elaboration and validation of this WebQuest, in order to ensure theoretical solidity, methodological coherence, and pedagogical relevance. The process was organized in stages that included initial construction, validation of the structure and content, re-elaboration, and empirical validation with participants, culminating in its final version. The data analysis was developed in light of the adopted theoretical framework and the contributions of experts, allowing for the problematization of potentialities and limitations. In this context, the research aims to validate a WebQuest as a theoretical-methodological process for promoting Multicultural and Intercultural Science Education in the initial training of educators, articulating theory and practice in the training of professionals sensitive to cultural diversity. With these purposes, we seek to answer the following guiding questions: “What is revealed in the totality of the WebQuest as a theoretical-methodological research resource in a qualitative investigation in the field of teacher training for science education?”; “How does the WebQuest enhance the problematization of sociocultural issues in science education, favoring the construction of critical and contextualized teaching in the initial training of educators?”; and “To what extent does the validation process of the WebQuest ensure its consistency as a theoretical methodological resource for qualitative research in the field of teacher training in science?”. The main results indicate that the WebQuest presents theoretical relevance in relation to the assumptions of Multicultural and Intercultural Science Education, structural clarity, and formative potential for articulating scientific knowledge and sociocultural issues in the school context. The contributions of the experts promoted adjustments to the WebQuest. Furthermore, empirical validation contributed significantly to the improvement of the WebQuest, by highlighting its applicability and pedagogical coherence. We conclude that the WebQuest is a promising theoretical methodological resource for the initial training of educators, by incorporating cultural diversity into science teaching. We also highlight the relevance of the validation process, which is still little explored in science education research.

Grounded in Agency Theory and Stakeholder Theory, this dissertation aims to analyze the influence of corporate governance on funding costs, credit granting conditions, and the financial performance of financial institutions in BRICS countries. The study is organized in the format of three quantitative articles and uses panel data from listed financial institutions, extracted from the Refinitiv Eikon® database, covering the period from 2020 to 2024, including Brazil, Russia, India, China, South Africa, Saudi Arabia, Egypt, the United Arab Emirates, and Indonesia. The analyses were conducted using the Stata® software, through panel data regressions for aggregated models and country-level models. The results indicate that the governance pillar and board independence do not present homogeneous effects across countries and across the three dimensions analyzed, with different signs and levels of statistical significance observed for funding costs, debt financing, and financial performance, which reinforces the dependence on the institutional and regulatory context. It is concluded that corporate governance is related to financial performance and financial decisions in a manner conditioned by the institutional and regulatory characteristics of each country. As a theoretical contribution, the study expands the understanding of the relationship between corporate governance and financial performance in financial institutions by demonstrating that such associations are not homogeneous across countries and depend on the institutional context. As a practical contribution, the findings provide support for boards of directors, managers, and policymakers in defining corporate governance structures and practices more aligned with national characteristics and with the objectives of stability and efficiency of the financial system. At the social level, the study is linked to the Sustainable Development Goals (SDGs) by evidencing how the relationships between corporate governance, funding costs, credit granting, and financial performance dialogue with the expansion of access to financial services, institutional strengthening, and the promotion of more transparent and responsible decision-making structures in the financial sector in emerging economies. The originality of the study consists of the integrated approach to three dimensions: funding costs, credit granting, and financial performance, in the context of BRICS, offering recent comparative evidence in a field still marked by fragmented results.

Analysis of the sequenced genome of Caulobacter crescentus demonstrates that it has numerous genes induced by agroindustrial residues and biomass, which encode enzymes used in industrial processes, including cellulases, xylanases and five different β-xylosidases. These enzymes are part of a growing demand in various industrial sectors, such as baking, paper clarification, fabric layering, animal feed, among others. In the present work, the mutant C. crescentus strain that overexpresses the xynA1 gene (CCNA_02894) encoding a bacterial endo-1-β xylanase (EC: 3.2.1.8) was created. The xynA1 gene was subcloned into the pAS22 vector, which features an xylose-inducible promoter that replaced the original xynA1 gene promoter, leading to an increase of more than 20 copies of the cloned gene product per bacterial cell. The conditional mutant obtained was named BS-xynA1 and grown in minimal medium M2 supplemented with xylose 0.3% (w/v) addition of different agro-indurstrial residues. The highest extracellular xylanase activity was 17.22 U mL-1 and specific activity 278.64 U mg-1 after 18 hours of bacterial growth in the presence of 0.2% (w / v) corn straw. Aliquots of crude enzyme extract with this high specific activity were used in the different tests applicability of biotechnological processes in regional flour industry baking laboratory. In baking tests, enzymatic addition reduced beating time by 9% and increased bread height by 18.2% compared to control, in addition to improving alveolar structure formation. In alveograph tests the enzymatic addition generated an increase of the following parameters compared to the controls: 18.8% increase in mass extensibility; 8.3% increase in mass deformation energy, showing an increase in mass force; and 5.2% increase in elasticity; In addition, the enzymatic addition also led to a 6.0% reduction in toughness and a 20.6% reduction in the toughness/elasticity ratio in relation to the control, demonstrating the decrease in mass stiffness by enzyme action. With the results of the analysis it was concluded that the enzyme extract containing xylanase I has applicability as a processing aid in the bakery industry because of its ability to improve the rheological characteristics of the dough, increasing the bread volume and improving the alveolar structure of the crumb. To our knowledge to date, this is the first time that xylanase I produced by homologous expression in C. crescentus has been successfully used in the bakery industry. This was made possible by the unpublished strain C. crescentus BS-xynA1. Publisher: Universidade Estadual do Oeste do Paraná Tipo do documento: Dissertação 2020-01-21T00:00:00Z
