Parâmetros físicos e análise de risco a escorregamentos: município do Crato (CE)
Full text linkAccording to estimates by the Brazilian Institute of Geography and Statistics (IBGE, 2018), approximately 8.3 million people reside in risk-prone areas across 872 municipalities in Brazil. The municipality of Crato, located in the state of Ceará, despite being situated in a relatively stable environmental setting, faces persistent challenges linked to unregulated land occupation and the absence of urban planning aligned with environmental protection—particularly on the slopes of the Chapada do Araripe. This study seeks to examine the physical parameters that condition susceptibility in the Chapada do Araripe region, as well as to delineate risk sectors within the Seminário neighborhood, considering the marked contrasts between high-income zones and areas inhabited by low-income populations. Topographic maps and geospatial analysis techniques were employed to identify susceptible zones within the study area. The results indicate that susceptibility is predominantly associated with elevated altitudes, steep slopes, and the presence of rocky escarpments. In the Seminário neighborhood, slopes exceeding 16.8°, the presence of scars from translational landslides, and exposed soil surfaces constitute a scenario of heightened landslide risk. The findings of this research are essential to support the formulation of public policies focused on disaster risk reduction and sustainable urban development in Crato.Según estimaciones del Instituto Brasileño de Geografía y Estadística (IBGE, 2018), aproximadamente 8,3 millones de personas residen en áreas expuestas a riesgos, distribuidas en 872 municipios de Brasil. El municipio de Crato, ubicado en el estado de Ceará, a pesar de encontrarse en un contexto ambiental relativamente estable, enfrenta desafíos persistentes vinculados a la ocupación irregular del suelo y a la ausencia de una planificación urbana articulada con la protección ambiental, en particular en las laderas de la Chapada do Araripe. El presente estudio tiene como objetivo analizar los parámetros físicos que condicionan la susceptibilidad en la región de la Chapada do Araripe, así como delimitar los sectores de riesgo en el barrio Seminário, considerando las marcadas desigualdades entre zonas de alto nivel socioeconómico y aquellas habitadas por poblaciones de bajos ingresos. Se emplearon mapas topográficos y técnicas de análisis geoespacial para identificar zonas susceptibles dentro del área de estudio. Los resultados indican que la susceptibilidad está principalmente asociada a altitudes elevadas, pendientes pronunciadas y la presencia de escarpas rocosas. En el barrio Seminário, pendientes superiores a 16,8°, cicatrices de deslizamientos translacionales y suelos expuestos configuran un escenario de alto riesgo frente a estos procesos. Los hallazgos de esta investigación son fundamentales para respaldar la formulación de políticas públicas orientadas a la reducción del riesgo de desastres y al desarrollo urbano sostenible en el municipio de Crato.No Brasil, segundo estimativas do IBGE (2018), cerca de 8,3 milhões de pessoas vivem em áreas de risco, distribuídas em 872 municípios. O Crato, situado no estado do Ceará, embora inserido em um contexto ambiental relativamente estável, enfrenta desafios decorrentes da ocupação irregular e da carência de planejamento urbano articulado à proteção ambiental, sobretudo nas encostas da Chapada do Araripe. Este trabalho tem por objetivo analisar os parâmetros físicos que condicionam a suscetibilidade na região da Chapada do Araripe, bem como identificar os setores de risco no Bairro do Seminário, considerando as desigualdades entre áreas de padrão socioeconômico elevado e aquelas habitadas por populações de baixa renda. Foram utilizados mapas topográficos e técnicas de geoprocessamento para reconhecer áreas suscetíveis na Chapada do Araripe. Os resultados indicaram suscetibilidade associada a altitudes e declividades acentuadas, somadas à presença de escarpas rochosas. No setor do Bairro do Seminário, inclinações superiores a 16,8°, cicatrizes de escorregamentos translacionais e solos expostos configuram um cenário propício ao alto risco a estes processos. Os achados deste estudo são essenciais para subsidiar políticas públicas de prevenção de desastres e ordenamento urbano no município do Crato
A Teoria Social Cognitiva e a escola democrática: diálogos com a realidade educacional
Full text linkThe Brazilian educational system deals with challenges in fostering a democratic school. Beyond expanding access, it is crucial to ensure persistence and provide quality education for all individuals who were admitted to the public educational system. In view of the significant role Psychology plays in addressing the complexities of the educational context, this article aims to explore the intersections between Social Cognitive Theory (SCT) and the development of democratic schools, in the Brazilian context. To this end, the theoretical foundations of SCT are revisited, highlighting: a) the principle of triadic reciprocity and mutual influences among environmental aspects—which also encompass historical, cultural, and political issues—intrapersonal aspects, and behavioral issues; and b) the concepts of individual and collective agency, which constitute the foundational pillars for the establishment of emancipatory education and the professional development of all educational staff. The article concludes with a discussion on the links that need to be established between the theoretical framework underlying Social Cognitive Theory and the advancement of an inclusive and high-quality educational system, with a specific emphasis on teacher education.El sistema educacional brasileño enfrenta desafíos en la construcción de una escuela democrática. Además de ampliar el acceso, es urgente que se impulsen que la permanencia y la educación de calidad para todas las personas que hoy ingresan a la red pública de enseñanza. Dada la importancia de la Psicología en la interlocución con la realidad educacional, el objetivo del presente artículo es presentar diálogos entre la teoría social cognitiva (TSC) y la construcción de la escuela democrática, considerando el contexto brasileño. Para ello, a través del rescate de las bases teóricas de la TSC, se destacan: a) el principio de reciprocidad triádica y de las influencias mutuas entre los aspectos ambientales, los cuales también incluyen factores históricos, culturales y políticos, los aspectos personales y los aspectos conductuales; y b) los conceptos de agencia individual y colectiva que constituyen las bases para el establecimiento de una educación emancipadora y para el desarrollo profesional de todos los agentes educativos. El artículo finaliza con reflexiones sobre los puentes a construir entre los fundamentos teóricos de la teoría social cognitiva y la construcción de una escuela inclusiva y de calidad, con un énfasis en la formación de profesores.O sistema educacional brasileiro vivencia desafios para a construção da escola democrática.

Application of life skills within the context of the BNCC: implications from research in military schools in the interior of Goiás: implications from research in military schools in the interior of Goiás.
No full textAbstract: This study aimed to assess teachers\u27 self-perceptions about their intention to teach life skills and compare students\u27 perceptions about learning life skills in military schools influenced by these teachers. The sample consisted of five teachers, aged between 28 and 45 years, each with at least four years of classroom experience. Additionally, 769 students participated in the study, with a mean age of 12.4 ± 0.92 years, representing both genders. The results indicated that, except for Teacher 1, who scored between 29% and 74% of the maximum possible scores across the investigated subscales of the P-CLSS-Q, the remaining teachers scored above 79% on the same subscales. Furthermore, classes taught by Teacher 3 showed lower scores in students\u27 perceptions life skills compared to other teachers in areas such as teamwork [χ2(4)=16,819; p=0,02], goal setting [χ2(4)=21,159; p=0,001], social skills [χ2(4)= 19,441; p=0,001], problem-solving [χ2(4)= 15.788; p=0,003], emotional skills [χ2(4)=20,457; p=0,001], leadership [χ2(4)=16,075; p=0,003], time management [χ2(4)=25,119; p=0,001], and communication [χ2(4)=21,561; p=0,001]. There were also minor variations in time management and communication life skills among classes taught by the other evaluated teachers. Based on these findings, teachers expressed interest in fostering a positive classroom climate to promote life skills (LS); however, students’ self-perceptions of LS learning were different, suggesting a need for targeted professional development to improve teachers’ teaching practices
Comparison of physical fitness during the pre-season of finalist and nonfinalist elite female soccer players
Full text linkAim: The aim of the study was to compare the pre-season physical performance of professional female soccer players between finalist and non-finalist teams. Methods: Thirty-two professional female soccer players (finalist group: 16 players; non-finalist group: 16 players) participated in the study. Two weeks after the beginning of the preseason, the players from two different teams that would participate in the same professional competition were submitted to physical performance evaluations such as jumps, a linear sprint in 20 m without and with ball handling, a change of direction in 20 m (COD), and the Yo-Yo IRL1. One of the teams was a finalist, the other did not qualify for the second phase of the competition. Results: The performance in the aerobic endurance test was significantly higher (p = 0.004) in the finalist group (1958.80 Å} 428.79 m) compared to the non-finalist group (1488.80 Å} 428.14 m), showing a large effect size (ES = 1.10). Conclusion: This study suggests that finalist teams have significantly higher levels of aerobic fitness during the preseason. Thus, coaches and coaching staff must consider that aerobic fitness can be decisive in the team\u27s success, emphasizing the process of physical training of this physical capacity in professional women\u27s soccer players

Effects caused by the use of an intermittent pneumatic compression boot on muscle recovery indicators after downhill running
Full text linkThe purpose of this work was to evaluate the effects of using an intermittent pneumatic compression boot (IPCB) on muscle recovery parameters after a downhill running (DRP) protocol. The study included 17 physically active men (23.3 ± 2.4 years, 82 ± 14.8 kg, and 173 ± 0.06 cm). The DRP consisted of 6 sets of 5 minutes, interspersed with 2 minutes of rest, with a slope of -3° and intensity corresponding to 70% (10.3 ± 1.1km/h) of peak aerobic speed. One limb was treated with IPCB and the contralateral limb was treated with placebo. IPCB application occurred immediately after, and 24h and 48h after DRP and lasted 30 minutes, with pressure of 100mmHg applied intermittently. The muscle recovery indicators evaluated were perception of delayed muscle soreness (DOMS), muscle quality in the rectus femoris (RF) and vastus lateralis (VL), in addition to concentric and eccentric peak torque (PT) in knee flexors and extensors. Significant interactions between time and treatment were observed only for VL DOMS (F=5.160; P<0.0001; η2p=0.02), indicating a lower perception of DOMS in this region when compared to placebo from 48 hours after DRP. For the other variables, only time effects were identified. We can conclude that the use of IPCB after a DRP was only effective in reducing DOMS in the VL region from 48 hours after DRP. Registered with REBEC (ID RBR-48hdw55)O objetivo deste trabalho foi avaliar os efeitos do uso de uma bota de compressão pneumática intermitente (BCPI) sobre parâmetros de recuperação muscular após um protocolo de corrida em declive (DRP). O estudo inclui 17 homens fisicamente ativos (23,3 ± 2,4 anos, 82 ± 14,8 kg e 173 ± 0,06 cm). O DRP consistiu em 6 séries de 5 minutos, intercaladas com 2 minutos de descanso, com uma inclinação de -3° e intensidade correspondente a 70% (10,3 ± 1,1 km/h) da velocidade aeróbica máxima. Um membro foi tratado com BCPI, e o membro contralateral foi tratado com placebo. A aplicação da BCPI ocorreu imediatamente após, 24 horas e 48 horas após o DRP e durou 30 minutos, com uma pressão de 100 mmHg aplicada intermitentemente. Os indicadores de recuperação muscular avaliados foram a percepção de dor muscular tardia (DOMS), a qualidade muscular no reto femoral (RF) e no vasto lateral (VL), além do pico de torque (PT) concêntrico e excêntrico nos flexores e extensores do joelho. Interações significativas entre tempo e tratamento foram observadas apenas para DOMS no VL (F=5,160; P<0,0001; η2p=0,02), indicando uma menor percepção de DOMS nessa região em comparação ao placebo a partir de 48 horas após o DRP. Para as outras variáveis, apenas efeitos temporais foram identificados. Podemos concluir que o uso da BCPI após um DRP foi eficaz apenas na redução da DOMS na região do VL a partir de 48 horas após o DRP. Registrado no REBEC (ID RBR-48hdw55
Leicester City FC won the English Premier League: a network analysis of the team for the season 2015-2016
Full text linkIt is crucial to examine Leicester City FC\u27s passing networks in the 2015-2016 English Premier League season as it provides detailed insights into player interactions within the team. Analysis of all 38 matches against 19 opponents, utilizing the OPTA database, revealed an average of 264.42 passes per game (SD = 72.65), totaling 10,048 passes between players. Gephi software (version 0.9.2) was employed to compute network metrics. One-way ANOVA was used to assess the influence of match location, performance, and opposition ranking on macro network metrics, as well as the influence of players\u27 positions on micro network metrics. Results demonstrated statistical differences between match locations and certain macro network metrics, indicating varying player interactions based on match locations and opposition levels. However, no statistical differences were found between team performance and examined macro network metrics, or between players\u27 positions and micro network metrics. This study\u27s main findings suggest that Leicester City FC exhibited distinct player interactions depending on match locations and the level of opposition during the season. Practical implications of these findings for coaching strategies or team performance analysis are worth exploring.Aim: It is crucial to examine Leicester City FC\u27s passing networks in the 2015-2016 English Premier League season as it provides detailed insights into player interactions within the team.

Variations in attack patterns and effectiveness between female and male middle players in top-level volleyball: Variations in attack between volleyball middle players of both genders
No full textAim: This study aims to analyze the associations between variables that predict the attack effectiveness of middle players (MPs) in top-level volleyball, recognizing their significant influence on the team\u27s offence under mostly optimal conditions while considering potential gender differences. Methods: Inferential statistics, multinomial logistic regression and multiple correspondence analysis were applied to analyze 843 attacks (508 for women and 335 for men) from the six top-ranked teams in the Men and Women World Championships 2018. Results: The analysis revealed that the two genders vary in some aspects of the game at the top level. Women MPs attack mainly from the area behind the setter, even after a good pass, against a team block but with lower attack effectiveness than men MPs who use to attack mainly in front of the setter, after an accurate pass against a single block. The attack effectiveness for both genders depends highly on the setting quality. Conclusion: In female volleyball, to increase effectiveness libero player is preferable to execute the first touch of the ball and MP to avoid off-speed attacks and to upgrade the effectiveness of spikes to zone 5 of the opponent court, while in male volleyball the existence of three attackers in the front row increases the odds for a winning attack.Aim: This study aims to analyze the associations between variables that predict the attack effectiveness of middle players (MPs) in top-level volleyball, recognizing their significant influence on the team\u27s offence under mostly optimal conditions while considering potential gender differences.

Análisis espacial de la vulnerabilidad a la contaminación de las aguas subterráneas en la cuenca hidrográfica Cauto, Cuba, empleando K-medias e imágenes satelitales: Spatial analysis groundwater contamination of vulnerability in the Cauto watershed, Cuba, using K-means and satellite imagery
Full text linkThe Cauto Basin is a watershed of national interest due to its large area and significant contributions of water resources in the eastern region of Cuba. It is one of the most polluted in the nation, and multiple projects are being developed there to promote responsible use of its resources and strengthen environmental education among its residents. To maximize the impact of these actions, it is necessary to deepen our understanding of the basin\u27s inherent fragility. The objective of this research was to analyze the spatial variation in the intrinsic vulnerability to groundwater contamination. To achieve this objective, k-means clustering analysis was used on variables that reflect its geological, geomorphological, soil, and hydrogeological characteristics. The spatiotemporal variation of the vegetation index and soil salinity were also analyzed using Landsat satellite images. The results showed that only 11% of the basin is highly vulnerable to pollution, and that between 2000 and 2023, vegetation cover decreased and soil salinity increased in large areas, highlighting the need to continue developing strategies for the protection and comprehensive, sustainable management of its resources.Keywords: Cauto watershed, groundwater vulnerability, K-means method, spectral indices.RESUMO - A bacia hidrográfica do Cauto, no leste de Cuba, é de interesse nacional devido à sua grande extensão e suas significativas contribuições para os recursos hídricos. É uma das bacias mais poluídas, e múltiplos projetos estão sendo desenvolvidos ali para promover o uso responsável de seus recursos. Esta pesquisa teve dois objetivos: mapear a variação espacial da vulnerabilidade intrínseca à contaminação dos recursos hídricos subterrâneos, e analisar a ameaça representada pela variação espaço-temporal da cobertura vegetal e da salinização do solo à qualidade das águas subterrâneas. Uma análise de agrupamento k-means das informações geológicas, geomorfológicas, pedológicas e hidrogeológicas da bacia mostrou que 9% e 14% das áreas foram classificadas como vulnerabilidade muito alta e alta, respectivamente, enquanto 66% foram classificadas como vulnerabilidade moderada e apenas 11% como vulnerabilidade baixa. O processamento e a interpretação das imagens de satélite Landsat mostraram que, entre 2000 e 2023, a cobertura vegetal diminuiu e a salinidade do solo aumentou, representando um impacto ambiental negativo ainda maior em áreas de alta e muito alta vulnerabilidade à contaminação das águas subterrâneas.

Resumen - La cuenca hidrográfica Cauto, en la región oriental de Cuba, es de interés nacional por su gran extensión e importantes aportes de recursos hídricos. Es una de las más contaminadas y en ella se desarrollan múltiples proyectos para favorecer un uso responsable de sus recursos. Esta investigación se planteó dos objetivos: cartografiar la variación espacial de la vulnerabilidad intrínseca a la contaminación de los recursos hídricos subterráneos; y analizar la amenaza que representa la variación espacio temporal de la cobertura vegetal y la salinización de los suelos sobre la calidad de las aguas subterráneas. El análisis de agrupamiento k-medias sobre la información geológica, geomorfológica, edafólogica e hidrogeológica de la cuenca, arrojó que las áreas clasificadas de muy alta y alta vulnerabilidad alcanzan el 9% y 14% respectivamente, mientras que el 66% clasifica de moderada y solo el 11% presenta baja vulnerabilidad. El procesamiento e interpretación de imágenes satelitales Landsat evidenció que entre los años 2000 al 2023 la cobertura vegetal disminuyó y la salinidad de los suelos se incrementó, lo que representa un impacto ambiental negativo aun mayor en áreas de alta y muy alta vulnerabilidad a la contaminación de las aguas subterráneas.

ABSTRACT - Cauto watershed, in eastern Cuba, is of national interest due to its large area and significant water resource contributions. It is one of the most polluted basins, and multiple projects are being developed there to promote responsible use of its resources. This research had two objectives: obtain a spatial variation map of intrinsic vulnerability to groundwater contamination; analyze the threat that represents the spatiotemporal variation of vegetal cover and soils salinization on groundwater quality. A k-means clustering analysis of the basin\u27s geological, geomorphological, edaphological and hydrogeological information showed that 9% and 14% of the areas were classified as very high and high vulnerability, respectively, while 66% were classified as moderate and only 11% as low vulnerability. The processing and interpretation of Landsat satellite images showed that between 2000 to 2023, vegetation cover decreased and soil salinity increased, representing an even greater negative environmental impact in areas of high and very high vulnerability to groundwater contamination.
