ABSTRACT The objective of this study was to regionalize 7-day 10-year low flows, long-term annual mean, and 90% and 95% permanence flows from Piquiri (PR) river basin. The following regionalization methods were adopted: Traditional, Linear interpolation, Chaves, Modified linear interpolation, and Modified Chaves. The equations obtained by the Traditional method, adding main river length or drainage density as independent variables, significantly improved R2 equations value. Streamflow forecasting by Linear Interpolation and Chaves methods were as good as those provided by the Traditional Method, thus, these methods could be applied to Piquiri River basin, especially when drainage area is the only available spatial information.

O aumento da demanda pelo uso da água na bacia do Rio Paracatu vem ocasionando sérios problemas ambientais e conflitos entre os usuários. Para a gestão mais eficiente dos recursos hídricos, é importante o conhecimento do comportamento hidrológico da bacia hidrográfica, no presente e no futuro, devido às fortes evidências de mudanças climáticas no planeta. O objetivo deste trabalho foi estimar a tendência de variação da disponibilidade hídrica na bacia hidrográfica do Rio Paracatu, até o final deste século, considerando dois cenários contrastantes de mudanças climáticas, um para altas emissões de CO2 (A2) e outro para baixas (B2). Para atingir esse objetivo, foi realizado o downscaling das precipitações mensais para os anos de 2001 a 2099, simulados pelo modelo de circulação geral do Hadley Centre (HadCM3). As precipitações interpoladas serviram como entrada em modelo do tipo precipitação-vazão, que possibilitou a estimativa das vazões mínimas em 21 estações fluviométricas distribuídas na bacia. Para o cenário A2, verificou-se tendência de aumento na disponibilidade hídrica em todas as estações fluviométricas, variando de 31 a 131% até 2099. Para o cenário B2, não foi verificada nenhuma tendência significativa.The increase of water use in the Paracatu basin is leading to deep environmental problems and conflicts among the users. For a more efficient water resources management, the knowledge of the basin's hydrologic behavior is important, in the present and in the future, due to the strong climatic changes evidences in the planet. The aim of this work is to estimate the water availability variation trends in the Paracatu river basin, from the beginning until the end of this century, considering two contrasting climate change scenarios, the first one to take account of high CO2 emissions (A2) and the other one for low emissions (B2). To achieve this objective, the monthly precipitation downscaling was accomplished, using data from 2001 to 2099 simulated by the Hadley Centre´s global circulation model (HadCM3). The precipitations were used as data input in a precipitation-flow model, which made possible the estimate of the minimum discharges in 21 gauged stations distributed in the basin. For the A2 scenario, an increase trend was verified in the water availability in all of the stations from 2001 to 2099, varying from 31 to 131%. For the B2 scenario no significant trend was verified.

Abstract This research aims to study the psycho-social impact of video games on K12 students. For this, a probabilistic topic modelling analysis method based on text mining approach has been performed. This process is based on nodes’ connectivity and it has been developed through K Means approach; by launching the Jenks-Breaks algorithm. The sex differences are calculated according to a nonlinear dynamics approach based on Hurst exponent and multifractal function and the influence of time with the application of the Sobel test. The results show which are the most used video games by K12 and their psycho-social impact on students based on four categories: (1) boredom and sadness, (2) happiness and socialization, (3) immersion, and (4) families' conflicts. There are significant differences between boys and girls depending on the games they use, a factor that increases when playing more than two hours a day. For boys, games like FIFA and Fortnite produce higher levels of immersion and family conflict, while for girls, games are perceived as sources of greater happiness and a means to reinforce friendship and camaraderie, particularly with games like Brawl Stars, Rocket League, and PKXD.

Abstract The COVID-19 pandemic forced the digitalization of education to be accelerated to continue the teaching–learning processes in confined populations. The irruption of this fact caused the evolution that had previously been occurring in the integration of digital technologies, and in general information and communication technologies (ICT), in education to be distorted, as their use multiplied exponentially in a few months. However, it is interesting to know how integrating these media and tools in the educational world evolved without having mediated an anomalous event such as the pandemic. This article studies the time university students in Spanish-speaking countries spent using the Internet for educational tasks in the pre-COVID era to determine whether this use was homogeneous in this common geographical and cultural space. Knowledge of these behaviors is valuable for analyzing their relationship with the then-current processes of ICT integration in higher education. It can serve as a basis for comparative studies of these trends and what happened during and after the pandemic. Among them is determining whether specific ICT integration strategies were not pedagogically adequate due to the situation’s urgency. The analysis of this study was descriptive and inferential statistics, based on the survey method with the application of data mining using software R. It was carried out over seven years (2012–2018) and applied to a sample of 2482 students from seven countries. The findings obtained have allowed us to determine that the use of the Internet by Spanish-speaking university students, in general, increased significantly over time in the pre-COVID era, in parallel to a more significant presence in educational processes, with conditioning factors in each country depending on its economy and political and social situation.

Background/Objectives: Parental involvement is vital for the academic success and overall development of students, particularly those with Autism Spectrum Disorder (ASD), who face unique educational challenges. This study investigates the influence of parental involvement on the academic performance and school adjustment of students with ASD, focusing on the interplay of cultural identity and first language in their educational and social growth. The research also seeks to identify the challenges parents face and the strategies they use to support their children. Method: Employing a qualitative, interpretive approach, this study involved 42 parents of secondary school students with ASD in Seville, Spain. Data collection included in-depth interviews and focus group discussions, allowing for a comprehensive understanding of parental experiences. Results: The study found that active parental involvement greatly enhances students’ academic performance and emotional well-being. Key strategies include creating structured home environments, utilizing assistive technologies, and fostering open communication with school staff. However, parents reported significant challenges, including limited school resources, communication barriers with educators, and a lack of ASD-specific training for teachers and parents. These challenges often hinder their ability to fully support their children’s education. Conclusions: Active parental involvement is crucial for the educational success of students with ASD. The findings highlight the need for improved communication between schools and families, increased resources, and targeted ASD training for both teachers and parents. Additionally, the study advocates for greater investment in assistive technologies to better support students with ASD. Addressing these needs could significantly improve the educational experiences and outcomes for these students.

This research has analyzed the application of gamification and game-based learning to primary education based on the evaluation of gamification by 308 primary education teachers in Spain. A quantitative and qualitative analysis was made of teachers’ competences, the tools and devices most widely used, didactic functionality, emotional competence and social skills. The results showed that teachers had a positive attitude towards gamification, and good knowledge and management of tools such as Genially, Kahoot and Google Classroom. With the appropriate resources, class planning and teacher training, game-based learning and gamification can boost student motivation and commitment, and foster enthusiasm for beneficial, pedagogical interactive processes.

The current study examines the relationship between digital competencies and collaboration attitudes among higher education students. To do so, data from 1316 students from 10 Spanish universities were analyzed and collected through a questionnaire named “Basic Digital Skills 2.0 of University Students” (COBADI®—Registered Trademark: 2970648). To provide context for the sample involved in this study, it is noteworthy that 50.5% of participants typically prefer to access the internet from home. Furthermore, it was observed that most of the respondents engage with the internet for over nine hours daily. The analysis of the results was conducted by calculating correlations between digital competencies and students’ collaboration attitudes. These correlations were computed using the Python programming language, with the libraries employed being pandas, numpy, and matplotlib. Students who perceive themselves as more competent in using digital tools tend to have a slightly higher disposition to collaborate with their professors in virtual environments. Some competencies are more closely associated with collaboration than others, with those that exhibit a stronger connection being key focus areas in teaching and curriculum development.

Abstract The design and management of various hydraulic structures (such as stormwater drains, bridges and dams) require the estimation of rainfall with duration of a few minutes up to 24 h or more. Intensity-duration-frequency (IDF) curves links probability of occurrence to a given rainfall intensity. The procedure for obtaining IDF curves basically involves two steps: (i) frequency analysis for different durations and (ii) modeling of IDF curves. In the first step, this study aimed to adequately select the upper tail weight of the following distributions: generalized extreme value (GEV), generalized logistic (GLO) and generalized Pareto (GPA). In the second step, this study aimed to evaluate the performance of three models of IDF curves. The traditional model (M1) was compared with empirical model (M2) and a second-order polynomial model (M3). To perform this study, rainfall data from the city of Caraguatatuba (São Paulo state, Brazil) for the period between 1971 and 2001 were used, for time intervals between 10 and 1440 min. The main conclusions were: (i) GLO and GEV had heavy upper tail while GPA had light upper tail, impacting quantiles with T > 100 years; (ii) M3 presents errors lower than M1 for return periods greater than 100 years.

Abstract The objective of this article is to analyze the didactic functionality of a chatbot to improve the results of the students of the National University of Distance Education (UNED / Spain) in accessing the university in the subject of Spanish Language. For this, a quasi-experimental experiment was designed, and a quantitative methodology was used through pretest and posttest in a control and experimental group in which the effectiveness of two teaching models was compared, one more traditional based on exercises written on paper and another based on interaction with a chatbot. Subsequently, the perception of the experimental group in an academic forum about the educational use of the chatbot was analyzed through text mining with tests of Latent Dirichlet Allocation (LDA), pairwise distance matrix and bigrams. The quantitative results showed that the students in the experimental group substantially improved the results compared to the students with a more traditional methodology (experimental group / mean: 32.1346 / control group / mean: 28.4706). Punctuation correctness has been improved mainly in the usage of comma, colon and periods in different syntactic patterns. Furthermore, the perception of the students in the experimental group showed that they positively value chatbots in their teaching–learning process in three dimensions: greater “support” and companionship in the learning process, as they perceive greater interactivity due to their conversational nature; greater “feedback” and interaction compared to the more traditional methodology and, lastly, they especially value the ease of use and the possibility of interacting and learning anywhere and anytime.

El objetivo del presente ensayo es exponer cómo el imaginario de vida campesina es trastocado por la idea de modernidad, el cual genera un punto de tensión que abre posibilidades de subvertir la realidad de manera organizada. Es un ejercicio de reflexión teórica desde la perspectiva de la escuela de Frankfurt y la teoría crítica a través de los estudios de Holloway, J. (2006; 2011). Con la técnica de grupo focal y la observación participante se trabajó con los sujetos y se entrevistó a actores sociales de comunidades campesinas e indígenas de la región del Totonacapan y de la sierra norte del estado de Puebla, información que se analizó a la luz de la investigación bibliográfica. En los resultados se expone la tensión que viven las familias al ser prisioneras de sus propios deseos por poseer la mercancía y lograr los modos de vida moderna. Se tiene que el acto de consumir significaciones de la modernidad lleva a menospreciar la cultura campesina, sin embargo, siguen siendo un referente de modos de vida más allá de sus contradicciones; que luchan por la vida ante la irrupción del capitalismo por expropiar sus recursos naturales. Este trabajo tiene como base las investigaciones realizadas por Lefebvre (1972), Heller (1994), Lindón (2000) sobre la vida cotidiana.

Se determinó la efectividad de la medicina herbolaria y su influencia sobre la calidad de vida desde la percepción del poblador del distrito de Laredo, Trujillo, durante 2019.

Este artículo presenta un estudio diacrónico circunscrito a dos titulaciones cursadas en la Universidad Pablo de Olavide de Sevilla en el que se describe una experiencia didáctica con 236 estudiantes que cursan asignaturas de “Tecnología de la Información y la Comunicación”. La acción formativa se desarrolló a través de un Seminario de Tecnologías Emergentes para analizar diversas aplicaciones de Realidad Aumentada en escenarios formativos y sus posibilidades educativas, además, de dinamizar en el alumnado actitudes proactivas y un uso competencial didáctico de las mismas. La investigación se ha implementado a través de una metodología cualitativa con el diseño de un mapa de categorías mediante el empleo del programa Atlas-Ti. Los resultados muestran que el alumnado de ambas titulaciones considera que la Realidad Aumentada es una tecnología emergente fácil de utilizar, dinamiza escenarios formativos motivadores y favorece el trabajo colaborativo. No obstante, también manifiesta que requiere de un elevado coste económico, puede incrementar la brecha digital y precisa de una formación especializada de los docentes.

In recent years, risk stratification has sparked interest as an innovative approach to disease screening and prevention. The approach effectively personalizes individual risk, opening the way to screening and prevention interventions that are adapted to subpopulations. The international perspective project, which is developing risk stratification for breast cancer, aims to support the integration of its screening approach into clinical practice through comprehensive tool-building. Policies and guidelines for risk stratification--unlike those for population screening programs, which are currently well regulated--are still under development. Indeed, the development of guidelines for risk stratification reflects the translational aspects of perspective. Here, we describe the risk stratification process that was devised in the context of perspective, and we then explain the consensus-based method used to develop recommendations for breast cancer screening and prevention in a risk-stratification approach. Lastly, we discuss how the recommendations might affect current screening policies. [ABSTRACT FROM AUTHOR]
