(Universidade Federal de São Carlos, 2025-02-18) Barboza, Vítor de Souza; Moreira, Pedro Augusto Franco Pinheiro; https://lattes.cnpq.br/5964404207962453; https://orcid.org/0000-0003-2843-775X
Accurate forecasting of electricity demand is a crucial element for the efficient and sustainable planning of the energy sector. This study focuses on a comparative analysis between the ARIMA (Autoregressive Integrated Moving Average) model and Recurrent Neural Networks (RNNs) for forecasting electricity demand in Brazil, utilizing advanced time series modeling techniques. The importance of this study is based on the growing need to optimize the use of energy resources, effectively balancing supply and demand. Accurate forecasting significantly contributes to preventing overloads and waste, which are essential factors for cost reduction and ensuring a stable supply. Furthermore, the rational use of electricity has a direct impact on environmental preservation, enabling the reduction of greenhouse gas emissions and supporting sustainability goals. In the Brazilian context, the relevance of this study is even more pronounced, considering that the country's energy matrix is one of the cleanest in the world, with a significant share of renewable sources. According to recent data, renewable sources will represent a substantial portion of Brazil’s installed electricity generation capacity in the coming years. Accurate demand forecasting is fundamental to the success of government initiatives and long-term planning in the sector, contributing to a more sustainable, economical, and equitable energy development for the Brazilian population. The primary objective of this study was to forecast electricity demand in Brazil by using and comparing two robust methods: the ARIMA model and RNNs. The specific objectives included an exploratory analysis of energy demand data, the implementation and tuning of ARIMA and RNN models, a performance comparison using the Mean Absolute Percentage Error (MAPE) metric, and the identification of the most effective method considering accuracy, complexity, and applicability to real-world data. The results obtained in this study demonstrated the effectiveness of both models in forecasting electricity demand in Brazil. The ARIMA model exhibited slightly superior accuracy, while the RNN model stood out for its computational efficiency. The comparative analysis revealed that, although ARIMA achieved higher accuracy in predictions, RNNs offer significant advantages in terms of processing time and scalability. These findings have important implications for the Brazilian energy sector, providing insights for optimizing energy resource planning and management, aligning with sustainable development goals and the country's energy transition targets.
Experiências parassociais, criatividade e Efeito Proteus: uma revisão sistemática da literatura
(Universidade Federal de São Carlos, 2025-02-18) Oliveira, Henrique Calzzetta; Schelini, Patrícia Waltz; https://lattes.cnpq.br/6185333517392859
Parasocial relationships (PSRs) are characterized as a form of medium- to long-term media interaction in which the viewer perceives having an affective social relationship with their idol, with the idol not participating reciprocally, while parasocial interactions (PSIs) are a related form of short-term media interaction that usually precedes the parasocial bond. This systematic literature review project plans to deepen knowledge on this topic through qualitative and quantitative scientific articles on the subject from its conception in 1956 up to the present year of 2024. The objective of this project is to organize and synthesize in an explanatory text the knowledge related to parasocial relationships and interactions and, secondarily, distinct forms of media interaction and the relationships of the parasocial phenomenon with the field of creativity. In this way, articles belonging to the Google Scholar and CAFe/CAPES databases that relate to parasocial relationships within the areas of communication, creativity, and cognitive psychology will be evaluated. Although this project presents a theoretical nature, the method was previously structured to reduce biases and demonstrate the actual quality of the field studied. Finally, there is still no research specifically on this topic in Brazil, and with the lockdown and consequent increase in maladaptive media consumption with the aim ofsupplying the lack of social interactions and the consequent formation of parasocial relationships as substitutes, it is necessary to fill this gap in the local literature.
Luto e pensamento contrafactual: compreensão e avaliação das dinâmicas individuais sobre o luto familiar
(Universidade Federal de São Carlos, 2025-02-18) Costa, Natalia Novaes Bueno; Schelini, Patrícia Waltz; https://lattes.cnpq.br/6185333517392859
This study explored the relationship between counterfactual thinking and the grieving process in individuals who experienced the loss of a loved one.Investigating various dimensions of counterfactual thoughts during grief, the study aimed to analyze the dimensions of counterfactual thinking, its relationship with guilt, the prevalence of upward and downward thoughts, as well as its functionality in the elaboration of grief and its association with pathological grief. Through a qualitative approach, participants who had been grieving for over a year shared their experiences, revealing that 70% reported guilt associated with upward thoughts, such as Why didn't I pay more attention?. The absence of downward thoughts was attributed to the severity of the event, supporting the literature indicating its limited effectiveness in alleviating discomfort in emotionally intense situations. While counterfactual thoughts may aid in emotional processing and learning, their impact proved to be ambiguous: 30% of participants identified positive effects, while the remainder reported negative or mixed effects. The findings contributed to the theoretical and practical understanding of grief, providing insights for more effective therapeutic interventions.
Modelagem longitudinal de uma aeronave em solo e implementação de um sistema de antiskid
(Universidade Federal de São Carlos, 2025-02-18) Strabello, Alexandre; Malavolta, Alexandre Tácito; https://lattes.cnpq.br/8477313173581967
Test procedures on the ground are essential during the aircraft development process. Considering the costs and complexity of these tests, the use of modeling and simulation tools is beneficial, particularly for systems like the antiskid system, which requires validation under diverse scenarios the aircraft may encounter throughout its operational life. This work aims to develop a longitudinal model of a generic aircraft using Euler-Lagrange equations to describe its dynamics, and to employ this model in the development of an antiskid system to enhance landing performance while preventing wheel skidding. The results demonstrate that the model, despite its simplicity, effectively represents the loads acting on the landing gear during braking, as well as the oscillations in pitch angle induced by the antiskid system’s modulation of brake commands. The antiskid system successfully reduced the aircraft’s stopping distance across various runway conditions, delivering particularly strong performance under adverse landing scenarios, and prevented prolonged wheel skidding, especially at high speeds.
Ação do óleo essencial de pimenta-rosa (Schinus terebinthifolius) no controle in vitro de Mycosphaerella fijiensis Morelet, agente causal da Sigatoka-negra em bananeiras (Musa sp.)
(Universidade Federal de São Carlos, 2025-02-18) Souza, Carlos Eduardo Gonçalves de; Mello, Ana Paula de Oliveira Amaral; https://lattes.cnpq.br/0308248590715976; https://orcid.org/0000-0003-4762-2635; https://lattes.cnpq.br/8100100092803185
Banana farming is an activity of extreme economic, social and cultural importance, strongly linked to family farming and consequently to the issues of man's permanence in the countryside. For man to understand the reason for his intersubjectivity with the rural environment and to make it the subject of his future aspirations and expectations, agroecological crops can be a point in favor of this self-understanding, since they aim to obtain efficient and safe cultivation methods that reduce risks to human health and the environment. In this sense, this study evaluated the effect of the essential oil of pink pepper or aroeira-mansa (Schinus terebinthifolius) on the in vitro growth of colonies of the phytopathogenic fungus Mycosphaerella fijiensis Morelet, the causal agent of Sigatoka-negra, which was isolated from banana leaves (Musa sp) with symptoms of the disease. The study was carried out with four treatments, carried out in petri dishes containing potato dextrose agar (PDA) culture medium: T1 (control) without application of oil, T2 with oil added to the PDA medium before solidification, T3 oil on the surface of the already solidified medium, and T4 oil on filter paper on the plate lid. Pink pepper essential oil was efficient in inhibiting the mycelial growth of Mycosphaerella fijiensis Morelet, in all methods tested (treatments), but the highest percentage of inhibition occurred in T3 at a concentration of 400 μL/20 mL. This result indicates that the use of pink pepper oil may be a promising alternative in disease management as opposed to the excessive use of pesticides in banana farming.
Aeração intermitente em biorreatores coluna de bolhas: uma alternativa eficiente para redução do consumo de ar
(Universidade Federal de São Carlos, 2025-02-18) Caporrino, Giancarlo Liceu; Almeida, Letícia Pereira; https://lattes.cnpq.br/7211415053407035; Badino Júnior, Alberto Colli ; https://lattes.cnpq.br/6244428434217018; https://orcid.org/0000-0001-8350-9846
This course completion work aimed to study intermittent oxygen transfer in pneumatic chemical bioreactors, through a comparative analysis with the method conventionally used for aeration of biochemical processes: the continuous regime. The aim was to verify the feasibility of replacing this method with the pulsed regime, as an efficient alternative for reducing gas consumption. For this purpose, preliminary tests were carried out under different conditions of opening and closing of the air flow control valve (decided through a central point factorial experimental design), in the water/air system, to determine important parameters in the efficiency of the process, such as the volumetric coefficient of oxygen transfer and oxygen transfer efficiency. These tests served as the basis for a statistical analysis of significance, which supported the decision to choose the conditions used (3vvm continuous and 3vvm 1F/3A) to conduct the cultures with biological beings. Then, experiments were carried out in duplicate with Saccharomyces cerevisiae yeasts in the two most promising conditions. The results demonstrated a 2% higher yield of cell growth to substrate consumption under intermittent aeration conditions. In addition, a 25% reduction in gas consumption was observed, representing significant savings in crops and contributing to the viability of the process.
Estratégias para redução do consumo de carvão ativado no tratamento de efluentes fenólicos: Análise técnica e econômica do processo em batelada de um e dois estágios
(Universidade Federal de São Carlos, 2025-02-18) Silva, Rogério Felito da; Ruotolo, Luís Augusto Martins; https://lattes.cnpq.br/6167735734348703
The treatment of industrial effluents containing toxic compounds has driven the search for alternative strategies to reduce process costs. Among these pollutants, phenolic compounds pose significant risks to human health and the environment, even at concentrations close to 1 ppm. Adsorption using activated carbon is widely employed in the industry due to its cost-effectiveness and operational simplicity, also enabling the use of renewable raw materials. Thus, this work aimed to develop strategies to reduce activated carbon consumption in batch adsorption processes. Phenol was used as a model compound, along with industrial effluents containing phenolic compounds. The study evaluated the optimization of operational parameters (contact time and pH) and multi-stage strategies using different adsorbents. It was found that the optimal contact time varied depending on the adsorbent, whereas a pH range of 3–4 maximized adsorption efficiency. The feasibility of a two-stage process without intermediate filtration depended on the desorption capacity of the adsorbent, whereas the two-stage approach with intermediate filtration showed potential to reduce the cost of a single-stage process by 33%. It is expected that these results will benefit companies operating in the sector by providing strategies to reduce adsorbent consumption and mitigate environmental impact.
Simulação da produção de ácido succínico por E. coli geneticamente modificada utilizando a metodologia de análise dFBA
(Universidade Federal de São Carlos, 2025-02-18) Duarte, Gabriel Parreiras; Furlan, Felipe Fernando; https://lattes.cnpq.br/4136352953168873
Succinic acid is a compound that stands out in the chemical industry due to its simplified structure, which allows its use in various sectors. Currently, it is obtained using fossil-based raw materials as the foundation of production. However, with the ongoing pursuit of reducing fossil resource consumption, biological routes have been increasingly studied, aiming for a more renewable and sustainable industry. This project aims to analyze, through simulations and using the methodology known as dynamic flux balance analysis (dFBA), the production of succinic acid using genetically modified Escherichia coli (E. coli) with glycerol as the substrate. This analysis was conducted using experimental data as a reference, with the Nelder-Mead algorithm as the primary optimization model. The objective function was the optimization of cell growth during the aerobic phase of the process and the production of succinic acid during the anaerobic phase. Alongside dFBA analysis, the flux balance analysis (FBA) methodology was also employed to assess the behavior of E. coli in different culture media. The results obtained deviated from those recorded experimentally in the reference study, exhibiting higher cell growth and lower succinic acid production, with shorter production times in both cases. This discrepancy between the simulated and experimental values indicates that dFBA analysis was not effective in accurately simulating laboratory processes. Therefore, further studies are necessary to determine the origin of these differences and to understand what adjustments could be made to improve the accuracy and reliability of the results.

(Universidade Federal de São Carlos, 2025-02-18) Valdez, Nicolas Ignacio; Lombardi, Ana Teresa; https://lattes.cnpq.br/6737850858443813; https://orcid.org/0000-0002-4299-3640; https://lattes.cnpq.br/5441069552006227; https://orcid.org/0000-0003-2982-4057
As cianobactérias são organismos unicelulares, procariontes e fotossintéticos de importância vital para o funcionamento da biosfera. A diversidade morfológica, fisiológica e metabólica dentro deste grupo acompanha sua ampla gama de aplicações. Culturas em grande escala são frequentemente realizadas em sistemas abertos sujeitos a flutuações climáticas, como o aumento da temperatura. Estes, por sua vez, podem afetar a fisiologia desses organismos, impactando a fotossíntese, a composição bioquímica e o crescimento. Rhabdoderma lineare é uma espécie comum em ambientes de água doce, caracterizada por alto conteúdo de proteínas (~75% da biomassa seca) e ausência de toxinas, tornando-a uma candidata potencial para aplicações biotecnológicas. Considerando o aumento global da temperatura e o fato de que uma parte significativa das culturas comerciais ocorre em ambientes naturais, entender os efeitos fisiológicos de diferentes temperaturas sobre essa espécie é importante. Neste estudo, padronizamos um protocolo para obter o rendimento fotossintético máximo em cianobactérias (Capítulo 1) e, posteriormente, realizamos culturas a 25, 30 e 35 °C, revelando diferenças significativas na taxa de crescimento, no rendimento fotossintético e no conteúdo de proteínas, carboidratos, lipídios e pigmentos (Capítulo 2). Esta pesquisa contribui para a biotecnologia de microalgas, explorando os efeitos da temperatura sobre R. lineare.

(Universidade Federal de São Carlos, 2025-02-18) Zanovelo, Marcelo Milharcix; Monari, Marcelo; https://lattes.cnpq.br/5944412594047895; https://orcid.org/0000-0002-5562-3235; https://lattes.cnpq.br/4606820766738681
The evolution of studies on Trip Attractors (TAs) indicates that their impacts on the surrounding area encompass various urban issues, ranging from the transportation system to socioeconomic development. This work presents a Neighborhood Impact Study (EIV) of a shopping center located in the southern region of São José do Rio Preto-SP, Brazil. The method consisted of surveying some of the minimum issues regulated by the Brazilian City Statute, as well as additional aspects that support the study. To achieve the objectives set for the study, comparative assessment methodologies were developed between the period before and after the building, in addition to data surveys of the current context in the city. Among the criteria with available comparative data, IBGE census data and territorial sensing complements in QGIS software were used. On the other hand, for the other analyzed indicators, data from the Infosiga-SP platform on traffic accidents, municipal public transport mapping, and volumetric vehicle counting in the field were used. The analysis of the results revealed increases of over 100% in both the road system and population, as well as an ongoing challenge related to traffic safety, with 42 accidents recorded at the same location over time. These findings helped to identify changes in the study area, reveal correlations between the indicators, and evaluate the mitigation measures taken by local authorities.
Uma avaliação do bioma Cerrado fundamentada na teoria da transição florestal
(Universidade Federal de São Carlos, 2025-02-18) Castro, Rafael Facanali; Bragagnolo, Cassiano; https://lattes.cnpq.br/3604206454925741; https://orcid.org/0000-0002-9177-3791
The Cerrado is considered a biome of high biodiversity, covering approximately 23% of Brazil's territory. It holds significant historical, ecological, cultural, and economic importance for the country while facing major challenges related to native vegetation loss and the expansion of the agricultural frontier. This study aims to assess the Cerrado biome based on the Forest Transition Theory (FTT), a theoretical model that evaluates changes in forest cover over time, considering economic, social, and environmental factors. This research utilizes data from the MapBiomas project, which compiles land use information from 1985 to 2023, along with relevant studies to identify the biome's forest transition phase and explore the direct and indirect factors influencing land use and the various mechanisms of forest transition. The results indicate that most of the Cerrado is in an intermediate stage of forest transition, characterized by persistent large-scale deforestation and native vegetation fragmentation. The assessment highlights the relevance of factors such as the expansion of agribusiness, global demand for commodities, especially soy and beef, and the relative lack of studies and funding dedicated to the biome. Additionally, the study discusses the hidden losses associated with both anthropogenic and natural reforestation, emphasizing the importance of strategies that reconcile forest recovery with the protection of remaining areas. The monograph concludes that the environmental conservation of the Cerrado requires the implementation of integrated public policies that incorporate FTT mechanisms, such as economic incentives and environmental governance, as well as the participation of local communities. It also underscores the need for sustainable management actions and global initiatives to reduce pressures on the biome, ensuring its preservation and the maintenance of its ecosystem services. This study contributes to the understanding of land-use dynamics in the Cerrado and provides insights for future research and policy-making aimed at the biome's sustainability.
O ambiente preparado para a criança de 3 a 6 anos de idade na educação infantil: a perspectiva de Maria Montessori
(Universidade Federal de São Carlos, 2025-02-18) Rocha, Rafaela Catarina Oliveira da; Marigo, Adriana Fernandes Coimbra; https://lattes.cnpq.br/4014738511373573; https://orcid.org/0000-0002-8784-3478; https://lattes.cnpq.br/9142515076500685; https://orcid.org/0000-0002-8955-539X
This undergraduate thesis investigates the preparation of the learning environment as proposed by Maria Montessori's approach in Early Childhood Education for children aged 3 to 6 years. This study represents a deeper exploration of findings obtained through the author's previous scientific research. The general objective is to understand the structuring of the school environment for children within this age group, as outlined by Maria Montessori, and to relate it to the guidelines of Brazilian Early Childhood Education. Methodologically, the study adopts a bibliographic research approach for source selection and employs content analysis techniques, as proposed by Bardin, for data examination. The research aims to contribute to the field of didactics, particularly regarding pedagogical practices in contemporary Early Childhood Education settings. The analysis results identified five fundamental categories in the preparation of the environment: the concept of the environment, the role of the educator, furniture, materials, and the external environment. These categories were synthesized into three main elements: the child, the environment (both internal and external), and a well-prepared educator. Additionally, two secondary elements were identified, namely materials and furniture.
Os principais impactos da Fake News na campanha de vacinação da Covid-19
(Universidade Federal de São Carlos, 2025-02-18) Pessoa, Luís Gustavo da Silva; Ribeiro, Renilson Rosa; https://lattes.cnpq.br/4919452710416508
This study focuses primarily on the period of Covid-19, starting in 2020 and extending to the post-Covid period in 2023. The general objective is to understand how fake news and the anti-vaccine movement influenced the Covid-19 vaccination campaign. To achieve this, the following specific objectives were defined: it was necessary to analyze key moments in Brazilian health history and understand how fake news and the anti-vaccine movement have always been present in our history. Addressing the main impacts of fake news on the Covid-19 vaccination campaign is justified because it is essential to understand what happened in order to deal with the effects of fake news, which continue to harm public health today. This study consists of theoretical research based on literature review and data collection from selected theoretical texts and materials, treated qualitatively. With the information gathered throughout the research and analysis of the data, it was possible to conclude that fake news is directly linked to all vaccination problems during Covid-19 and in the post-Covid period, affecting even other vaccines and diseases that had been eradicated before 2020.
Análise de atos de concentração econômica e de condutas anticompetitivas no mercado de cimento no Brasil
(Universidade Federal de São Carlos, 2025-02-18) Silva, Eduardo Polini Marinho da; Pitelli, Mariusa Momenti; https://lattes.cnpq.br/2810339285129049
Cement is a widely used material and holds significant importance and impact in the construction sector in Brazil and many other countries. The cement market is characterized by relevant concentration within a small number of economic groups (Cunha; Fernandez, 2003; Dornelas, 2013; Santos, 2011), which, according to theory, increases the likelihood of the exercise of market power (Church; Ware, 2000). In this context, the present study aims to analyze economic concentration acts and anticompetitive practices judged by the Administrative Council for Economic Defense (Cade) between 2015 and 2023. Regarding the reviewed concentration acts, it was observed that most were approved without restrictions, and the majority were also processed under a fast–track procedure. As for anticompetitive practices, all the administrative proceedings were dismissed. Thus, although there were economic concentration operations, it was found that they did not harm competition. Furthermore, the administrative proceedings concerning alleged anticompetitive practices judged during the study period were also dismissed.
Mais que mães, mulheres… A voz das puérperas sobre os cuidados recebidos na Atenção Básica em Saúde
(Universidade Federal de São Carlos, 2025-02-18) Cabral, Bruna Rego Rangel; Fornereto, Alana de Paiva Nogueira; https://lattes.cnpq.br/0361502737203825; https://orcid.org/0000-0002-9503-8153; https://lattes.cnpq.br/2858546512465348; https://orcid.org/0009-0001-0414-4613; Bussadori, Jamile Claro de Castro; Moura, Aline Silva de; https://lattes.cnpq.br/4549657176930635; https://lattes.cnpq.br/1802598771589178; https://orcid.org/0000-0002-3048-5593; https://orcid.org/0000-0002-6636-0274
A brief historical contextualization highlights how slow and conflict-ridden the process has been to broaden the understanding of women's health beyond reproductive characteristics and the maternal role, as well as the fundamental role the feminist movement has played, and continues to play, in this context. The search for bibliographic references that address women's health in a comprehensive manner reveals a significant gap regarding the postpartum period, especially within the context of Primary Health Care. This gap justifies the development of this study. It is a gap identified even in protocols and documents from the Ministry of Health, which consequently impacts the absence, or limited existence, of strategies for postpartum care in Primary Health Units, and leads to discrepancies in how health professionals and teams perceive the necessity of such strategies. When they do exist, these strategies are primarily focused on the physical health of the child and the mother, while women's broader needs are often relegated to a secondary role. This study was conducted at the Redenção Primary Health Unit, located in the municipality of São Carlos, in the interior of São Paulo state. Its objectives were to understand the postpartum care actions offered to women within Primary Health Care and to analyze, from these women’s perspectives, whether they received the care they expected. To achieve this, a field study with a qualitative, exploratory, and cross-sectional design was carried out. Data collection took place between august and december 2023, through semi-structured interviews containing guiding questions focused on the women's postpartum needs and the care strategies offered by the Primary Health Unit during this period. For data analysis, Bardin’s (2011) content analysis technique was used, and for the discussion, the theoretical framework of comprehensive care, proposed by Ayres (2009), was adopted. The results led to the identification of three categories that warrant further exploration: therapeutic itinerary, bond with health professionals, and constructing my own way of mothering. The initial objectives of this study were achieved and enabled a better understanding of the provision and challenges involved in postpartum care within the context studied. The findings underscore the urgent need for further research in this area, in order to improve the quality of care provided to women during this highly significant stage of human development.

Influência da luz na produção de biomassa de microalgas para biocombustíveis: modelagem cinética e análise da literatura
(Universidade Federal de São Carlos, 2025-02-18) Salomão, Arthur Corrado; Horta, Antonio Carlos Luperni; https://lattes.cnpq.br/5923938048634505; https://orcid.org/0000-0002-3042-0351; https://lattes.cnpq.br/9893750790180622
With population and technological growth, the demand for energy has increased significantly in recent years. In this context, third-generation biofuels, obtained from microorganism biomass, have emerged as a sustainable alternative. Thus, the present study aimed to evaluate how different lighting conditions, including light intensity and spectrum, influence the growth rate and biosynthesis of biochemical compounds of interest in microalgae, with an emphasis on the production of biofuels, such as biodiesel and SAF. For this purpose, the effect of light on the growth of microalgae was mathematically modeled and evaluated, choosing the species Scenedesmus obliquus, in addition to performing a literature analysis. The results indicated that the mathematical model developed presented good predictive capacity in relation to light intensity, cell concentration and product concentration, since both the simulated values and the behavior remained close to the experimental data. The literature analysis revealed a diversity in the optimal lighting conditions, mainly in relation to light intensity, evidencing that such conditions can vary according to the cultivated species, the cultivation conditions and the objectives of the production process, which determine the metabolites of interest. The literature analyzed shows a predominance of blue and red light, alone or in combination, as the most efficient spectra for microalgae growth and biomass production. When comparing the experimental results with the literature data, there is agreement on the relevance of blue light for microalgae growth. However, experimentally, it was found that red light had a lesser impact. This discrepancy may be related to differences in cultivation conditions, in the species of microalgae used, or to limitations of the modeling applied.
Relação entre compulsão por compras aspectos da inteligência emocional e personalidade
(Universidade Federal de São Carlos, 2025-02-18) Carvalho, Beatriz Ponce de Leon Campos Pimentel Ferreira; Miguel, Fabiano Koich; https://lattes.cnpq.br/8404130543685490
This research project aimed to investigate the relationship between compulsive shopping, emotional intelligence (specifically emotional understanding and emotional regulation), and personality, focusing on the Brazilian population. Approximately 414 individuals over 18 years of age who regularly made online purchases participated. To assess emotional understanding, emotional regulation, personality, and compulsive shopping habits of each participant, respectively, the TOHE and QoRE questionnaires, the BFI-2 scale, and the Richmond Achievement Scale were used. The research sought to contribute to the advancement of psychological science by examining the levels of emotional understanding and emotional regulation of participants who engage in different intensities of online shopping, as well as helping to establish diagnostic criteria related to the phenomenon. The study is justified by the significant prevalence of compulsive shopping in society and the importance of identifying risk factors for the development of this behavior, which can have negative financial and emotional consequences. The results indicated that compulsive online shopping is positively associated with impulsivity and negatively associated with resilience and sociability. Additionally, a positive relationship was observed between online shopping addiction and neuroticism, and a negative relationship with conscientiousness and agreeableness. Regression analysis revealed that age, sex, and income were significant predictors of online shopping addiction, with young women of high income showing a higher risk. These results contribute to the understanding of online shopping addiction and may assist in the development of targeted interventions for the prevention and treatment of the problem.

Neoliberalism has intensified precarious relations evidenced in the uberization of work. During the pandemic, this trend has exacerbated inequalities. It is important to analyze the psychological impacts of these new working relationships, especially among men over the age of 30. The aim of this study was to understand the occupational trajectory of app drivers and their experiences of suffering. This is a qualitative, cross-sectional and exploratory study. Four drivers took part in the study, two of whom were COOPAMA cooperative members and the other two self-employed app drivers with no connection to cooperatives. Data collection consisted of the following instruments: (a) socio-economic questionnaire; (b) semi-structured individual interview script; (c) field diary. The interview sessions were audio-recorded and transcribed in full. The research protocol was approved by the Human Research Ethics Committee of the Federal University of São Carlos (CAAE No. 77876024.6.0000.5504). The data was analyzed using thematic analysis. The material collected was interpreted according to the theoretical framework adopted in the study.
Esquerda ou direita: elaboração de um teste psicológico que meça alinhamento político no cenário nacional
(Universidade Federal de São Carlos, 2025-02-18) Crisostomo, Rafaela Costa; Miguel, Fabiano Koich; https://lattes.cnpq.br/8404130543685490
During the 18th century, at the height of the French Revolution, the terms "right" and "left," related to the political spectrum, were coined. Over the centuries, these words have acquired new meanings, been distorted, and even used as insults. In order to measure political positioning, some scales have been developed, such as Adorno's F-scale. However, there is no valid psychological test in Brazil capable of measuring political alignment in general. In this sense, the present study aimed to fill this gap in Brazilian psychometrics: for this purpose, a political alignment scale was developed, capable of classifying individuals as "left-wing" or "right-wing," either in milder degrees, that is, closer to the center, or more aligned with the political poles.
