The absence of actions to manage information in the operational sphere (on the shop floor) affects the communication quality in this sector. Communication problems, in turn, can negatively impact operational security and organizational culture. Thus, this study proposed a model to analyze communication in the operational sector using the Structural Equation Modeling (SEM) technique. A mathematical model was presented, consisting of 1 exogenous latent variable, knowledge management, and 4 endogenous variables: (i) oral communication; (ii) written communication; (iii) Man interaction with information and communication technologies (ICTs); and (iv) the operational communication. The case study was carried out in a land-based oil production region in the Northeast of Brazil where data were collected through a structured questionnaire with a Likert scale response. After analysis using the SEM, and using the same database, a supplementary study was carried out based on the development of a neuro- fuzzy model to assess information management in the operational sector. The SEM confirmed 6 of the 9 hypotheses proposed in the theoretical model. The results obtained showed that operational communication is directly influenced by knowledge management and by man interaction with ICTs. Written communication and oral communication had a direct influence on man interaction with ICTs and had an indirect influence on operational communication, thus, communication on the shop floor occurs predominantly through technologies. Knowledge management had a direct influence on the 4 endogenous variables, with strong explanatory and predictive relevance effects. The result of the neuro-fuzzy model showed that information management on the shop floor improves as actions are taken to acquire, store and distribute information about the operational routine. The model presented relevant contributions to the refinement of theory and practical contributions to support information management on the shop floor.

In recent years, the field of soundscape studies has gained increasing prominence, driven by the need to transcend traditional approaches to urban environmental management that focus exclusively on noise control policies. Adopting a multidisciplinary perspective, the assessment of urban sound environments integrates both subjective variables, related to user perception and objective physical parameters inherent to the specific context and location. In this regard, the development of analytical tools capable of understanding and predicting perceptual responses to planning decisions through predictive modeling is essential. This doctoral thesis proposes a methodology for the evaluation of urban soundscapes based on the development of predictive models and their application in public spaces in the city of Maceió, Alagoas, Brazil, specifically along the seafront of the Ponta Verde and Pajuçara neighborhoods. The study adopts an applied research design, encompassing field data collection in accordance with the ISO 12913 normative series, including soundwalks, questionnaires, and acoustic measurements. A novel methodological approach is presented, involving the construction of a mixed questionnaire grounded in methods A and B of ISO/TS 12913-2, enriched with contextual and visual information. Furthermore, a procedure for acoustic environment characterization is proposed, aligned with ISO/TS 12913-3, and complemented by in-depth analyses of interrelations among perceptual and contextual factors. This is followed by correlation analyses and the identification of relevant indicators (empirical data) and descriptors (measures of perceptual response) for model development. The modeling framework comprises both linear predictive models (multiple linear regression) and nonlinear models (artificial neural networks – ANN). The ANN-based models demonstrated up to 35% greater predictive performance compared to linear models, with one model achieving a coefficient of determination (R²) of 0.98. The methodological advancements presented herein offer a significant contribution to the technological field of urban soundscape assessment, providing support for evidence-based decision-making by researchers and urban planners. This research expands the theoretical and practical horizons of soundscape studies by proposing innovative approaches for the characterization and predictive modeling of urban acoustic environments.
"Entre Jesus, Apolo e Obatalá”: o hibridismo transcontinental do Vale do Amanhecer e as relações de poder

This research had as its object of study to analyze the power relations, which at an institutional level, ranging from the command of work to the national/international command of religion, at a spiritual level organizes the hierarchy between men and women, present in the Vale do Amanhecer, through the perception of mediums. In order to respond to the problem presented by the object, the following objective was formulated: to investigate the religious practices of the Vale do Amanhecer, based on the analysis of its history, associating it with the story of Tia Neiva and relating it to transcontinental hybridism. This analysis will have as categories of analysis the transcontinental hybridism and the power relations. The choice for transcontinental hybridism occurred because it was not possible, in our analysis, to dialogue with the syncretism category, since the pantheon of the Valley forms a mosaic with entities from various faiths and continents such as Candomblé, Umbanda, Christianity, Kardecism, religions of Ancient Greece and Egypt, Buddhism and ufology entities as elements of the book Exilados de Capela, involving spiritual entities from religions of four continents that were incorporated into the Vale do Amanhecer, working in order and synchrony, without the mirroring of the entities, as was imposed on religions of African origin, in which an Orixá represented a Saint, as a way for the enslaved to be able to worship their faith without being repressed by their masters. To collect the data, forms with specific questions about the topic were sent, and the responses were analyzed using a quantitative and qualitative approach, in which the percentages, individual analysis, and the combined responses made it possible to understand the mediums' view of how they observe the hierarchy, defined by power relations, in a hybrid and transcontinental community. This research also focused on analyzing the place that women occupy in the hierarchy of the Valley. The research showed that most women perceived a devaluation of the place occupied by the female public, which leads to a contradiction, since the religion was created by Tia Neiva, who after her death was elevated to one of the main spiritual entities of the Vale do Amanhecer. This study will contribute to a better understanding of the relationships that are established in the Valley, as well as give visibility to the religious and spiritual practices experienced in the Vale do Amanhecer. The thesis is based on the dialogue between the categories of hybridism, taking as a basis Cancline (1997), a genre in which Nunes's (1985) thinking fits into the issue of women's protagonism in the Valley, and finally, multiculturalism based on the concepts of Touraine (1997). The thesis proposes to describe the Vale do Amanhecer in its historical context and in its relations with the religions that hybridize with it, emphasizing Catholicism, Kardecism and Umbanda, which exert a strong influence, both in the rituals and in the mediums and patients who attend.
