Cosmopolitismo y modernidad en la formación de la coiné andaluza. Estudio sociofonético de la realización de la fricativa velar sorda /x/ en la ciudad de Málaga.
No full textTirant Open AccessAgenda 2050: el español de Málaga: procesos de variación y cambio espaciales y sociales (PID2019-104982GB-C5-2)El objetivo de este trabajo es mostrar cómo las variables de pequeña escala, como el cosmopolitismo, la urbanidad o la modernidad, favorecen los procesos de convergencia hacia el español estándar en mayor medida que las características macrosociales básicas, como el nivel de instrucción. Para ello se presentan los resultados del análisis del fonema fricativo velar sordo /x/ en el corpus PRESEEA-Málaga.
En Andalucía, la realización principal de este segmento es la aspiración faríngea [h], que alterna con pronunciaciones cercanas al estándar [x] y otros alófonos muy debilitados, como la elisión (Narbona-Jiménez, Cano-Aguilar y Morillo-Velarde 2003: 201-204). Los estudios de corte sociolingüístico indican que la pronunciación fricativa es más frecuente entre los jóvenes instruidos, mientras que las variantes aspiradas y elididas se dan principalmente entre hablantes mayores sin estudios (Melguizo-Moreno 2008, Moya-Corral 2016). Estos datos parecen indicar que la variante fricativa es un rasgo propio de la variedad intermedia emergente en Andalucía (Villena-Ponsoda, 2008).
Para medir el efecto de las variables de pequeña escala en las realizaciones alofónicas de /x/ se reconstruyó la historia de vida de los informantes (Labov 2001: 385-411). Los resultados parecen indicar que los sujetos más cosmopolitas son los que favorecen las realizaciones fricativas, independientemente de su nivel de instrucción.Universidad de MálagaAgencia Estatal de Investigación del Ministerio de Ciencia e Innovació
How do flexible working time policies, telework from home and work fatigue impact on the work-life balance?
Full text linkPurpose: Human resource management (HRM) has become one of the main tools for improving organisational performance and satisfaction. Numerous research studies have shown the importance of promoting work-life balance (WLB), as it influences individual and family well-being. In this context, organizations are looking for strategies such as flexible working hours (FWH) or telecommuting from home to facilitate WLB. The aim of this study is to analyse how these practices, together with physical and mental fatigue, impact both WLB and overall performance, offering implications for HRM.
Methodology: A theoretical model with 4 variables was designed. To test the hypotheses, a structural equation model with partial least squares was applied. A subsample of 13,724 responses from the 2021 special edition of the European Working Conditions Telephone Survey was analysed.
Findings:Teleworking from home (TWH) is shown to negatively impact WLB, highlighting the challenges of balancing work and personal spheres simultaneously. However, the impact of TWH on work fatigue was not statistically significant. In contrast, flexible work schedule policies showed a positive impact on both improving WLB and reducing work-related fatigue (WF). Furthermore, WF emerged as a key factor in the relationship between flextime and WLB, but not in the relationship with TWH. Finally, TWH acted as a moderator in the relationship between flextime and WLB, suggesting that the combination of both practices contributes to reduced fatigue and improved WLB.
Practical implications: This study offers key guidance for the design of human resource policies focused on employee well-being. Findings show that combining home-based teleworking with flexible schedules enhances WLB and reduces WF. Organisations can improve performance and job satisfaction by adopting strategies that integrate both practices. Additionally, clear boundaries for digital disconnection and workload adjustment are recommended
The moderation role of self-efficacy on the relationship between transformational leadership and enjoyment in physical educational students
No full textBackground:
Enjoyment in physical education classes is recognized as a key factor in fostering a positive relationship with physical activity. Its significance as a component for sports participation is emphasized.
Purpose:
This study investigates the moderating role of self-efficacy in the relationship between the transformational leadership of physical education teachers and students’ enjoyment during classes. The hypothesis is that students’ perceived self-efficacy moderates this relationship.
Methods:
An associative and explanatory approach was employed. The study involved 429 adolescents (205 boys, 224 girls) aged 14–16 from the province of Málaga, Spain. Data was collected using three questionnaires: the Transformational Teaching Questionnaire to assess the teacher's transformational leadership, the Motor Self-Efficacy Scale to measure students’ motor self-efficacy, and the Intrinsic Satisfaction in Sport Instrument to evaluate students’ enjoyment in physical education classes.
Results:
The findings revealed a positive relationship between teachers’ transformational leadership and students’ enjoyment in physical education classes. Moreover, students’ motor self-efficacy was found to moderate this relationship: Specifically, the positive effect of transformational leadership on enjoyment was more pronounced among students with low self-efficacy, whereas the effect was less evident among students with high self-efficacy.
Discussion:
The study concludes that transformational leadership influences students’ enjoyment in physical education classes, but its impact is moderated by students’ perceived self-efficacy. These results emphasize the importance of training physical education teachers in transformational leadership strategies to improve students’ experiences, fostering active and healthy lifestyles from adolescence into adulthood
Dataset_Profiles_Smartphone_Emotional_intelligence_FOMO.
No full textBackground: Adolescents are the most vulnerable population for problematic smartphone use (PSU). The scientific literature provides evidence that factors such as fear of missing out (FoMO) and emotional intelligence (EI) can be related to problematic internet behaviours, but few studies have been conducted on PSU in adolescents. This study aimed to examine how FoMO and EI might explain PSU in adolescents. Methods: The sample consisted of 537 students (12–17 years old) who completed scales assessing problematic smartphone use, fear of missing out, and emotional intelligence. Results: The results showed in both cases moderate, significant and positive correlations between PSU and FoMO, while significant and negative correlations between PSU and EI were observed. In addition, high FoMO and deficits in EI were found to explain part of the variance in PSU. Conclusions: The results are discussed based on the Theory of compensatory internet use. The need to address EI and FoMO in educational contexts is also justified.Parte del proyecto I+D+i PID2020-117006RB-I00, financiado por MCIN/AEI/10.13039/501100011033Grupo de investigación Applied Positive Lab CTS-1048G-FEDER (Junta de Andalucía)Universidad de Málaga (M.

Efectos de un programa de rehabilitación cardíaca sobre la calidad del sueño en pacientes cardiópatas con y sin insuficiencia cardiaca.
Full text linkLos trastornos del sueño son muy frecuentes en pacientes que han sufrido un episodio de síndrome coronario agudo (SCA), con angina de pecho y/o insuficiencia cardíaca (IC), así como en pacientes sometidos a cirugía cardíaca. Varios metanálisis muestran que la mala calidad del sueño es un factor de riesgo importante para las enfermedades cardiovasculares, por lo que las intervenciones dirigidas a la calidad del sueño también podrían, a su vez, afectar positivamente el riesgo de desarrollar enfermedades cardiovasculares. Más concretamente, la evidencia sugiere que los trastornos del sueño están relacionados con varios factores de riesgo cardiovascular (FRCV), incluyendo obesidad, hipertensión, diabetes mellitus tipo 2 y enfermedades cardiovasculares.
La corrección de los FRCV juega un papel fundamental en los programas de rehabilitación cardíaca (RC) y por lo tanto la calidad del sueño también debería considerarse en los programas de tratamiento. Sin embargo, a pesar de estas consideraciones, los efectos de los programas de RC convencionales sobre la calidad del sueño han recibido poca atención en la literatura científica actual; además, en la práctica clínica diaria muchas veces este aspecto no es evaluado ni tratado de forma individualizada.
Estudios previos sugirieron que asistir a un programa de RC puede mejorar la calidad del sueño, así como los trastornos respiratorios asociados al sueño en pacientes cardíacos. Además, los trastornos del sueño parecen correlacionarse con síntomas ansiosos y depresivos en pacientes sometidos a RC, y se ha sugerido que un programa centrado en el ejercicio puede mejorar estos aspectos. Algunos trabajos se centraron específicamente en pacientes con IC y reportaron resultados similares.Sin embargo, a pesar de que la literatura existente destaca la asociación entre la IC y la mala calidad del sueño, hasta donde sabemos, no se han realizado estudios previos para evaluar posibles diferencias en la calidad del sueño entre los pacientes con IC y aquellos sin ella. Por ello, el objetivo principal de este estudio fue evaluar los valores iniciales y los cambios en la calidad del sueño en pacientes que asisten a un programa de RC, y comparar las diferencias en la calidad del sueño entre pacientes con y sin IC. Los objetivos secundarios fueron describir si existe relación entre calidad de sueño y calidad de vida, ansiedad, depresión y capacidad funcional, así como entre los cambios registrados para estas variables, y comparar si hay diferencias entre los pacientes con y sin IC
Simulador eficiente de antenas ópticas integradas con radiación en ángulos arbitrarios.
Full text linkThe increasing interest in free-space optical communications (FSOC) and Light Detection and Ranging (LiDAR), requires gratings capable of emitting highly collimated beams, with Rayleigh distances in the order of centimeters or even meters. This requires the design of weak-strength gratings, which radiate little amount of power per unit length. In addition, dynamic beam steering is essential for these applications, enabling efficient environmental scanning and tracking of moving objects. This work aims to develop an accurate and efficient simulation tool to accelerate the design of weak-strength gratings, and study the effect of feeding light with arbitrary angles into the antenna. Comparison with results obtained with a full-vectorial 3D FDTD simulator, shows very good agreement with the advantage of decreasing simulation times by up to a factor of ×514
Validación de un método tridimensional para el ajuste del calzado en la prevención del dolor podológico.
Full text linkEl dolor en el pie es un problema de salud mundial que afecta a un porcentaje significativo de la población adulta, con una prevalencia que varía entre el 13% y el 36%. Este dolor es particularmente prevalente en las personas mayores y se asocia con diversas consecuencias negativas, como caídas, discapacidad locomotora y una reducción de la calidad de vida. Los factores que contribuyen al dolor de pie son tanto intrínsecos (como el género, la edad y el índice de masa corporal) como extrínsecos, siendo uno de los más relevantes el uso de calzado inadecuado.
El objetivo principal de esta tesis es describir y validar un modelo tridimensional del pie que represente con precisión su morfología. Este modelo permitirá mejorar la adaptación entre el pie y el calzado, lo que podría prevenir desajustes, dolor y patologías asociadas al uso de calzado mal ajustado. Adicionalmente, se establece como objetivo específico determinar si el Índice Volumétrico de adecuación del calzado (IVAC) está asociado al dolor en el pie, y también identificar los factores predictivos del dolor en la población adulta. En particular, se examina cómo los cambios volumétricos del pie, generados por la posición del cuerpo o la duración de la actividad, pueden influir en la aparición de dolor.
La tesis contribuye a proporcionar una herramienta objetiva para evaluar el ajuste del calzado, considerando no solo factores como la talla, sino también las variaciones volumétricas del pie, que a menudo no son tenidas en cuenta en el diseño del calzado. El estudio busca ofrecer soluciones prácticas para mejorar la salud del pie, reducir el dolor y mejorar la calidad de vida de las personas adultas

Federated deep reinforcement Learning for ENDC optimization
Full text link5G New Radio (NR) network deployment in Non-Stand Alone (NSA) mode means that 5G networks rely on the control plane of existing Long Term Evolution (LTE) modules for control functions, while 5G modules are only dedicated to the user plane tasks, which could also be carried out by LTE modules simultaneously. The first deployments of 5G networks are essentially using this technology. These deployments enable what is known as E-UTRAN NR Dual Connectivity (ENDC), where a user establish a 5G connection simultaneously with a pre-existing LTE connection to boost their data rate. In this paper, a single Federated Deep Reinforcement Learning (FDRL) agent for the optimization of the event that triggers the dual connectivity between LTE and 5G is proposed. First, single Deep Reinforcement Learning (DRL) agents are trained in isolated cells. Later, these agents are merged into a unique global agent capable of optimizing the whole network with Federated Learning (FL). This scheme of training single agents and merging them also makes feasible the use of dynamic simulators for this type of learning algorithm and parameters related to mobility, by drastically reducing the number of possible combinations resulting in fewer simulations. The simulation results show that the final agent is capable of achieving a tradeoff between dropped calls and the user throughput to achieve global optimum without the need for interacting with all the cells for training.This work was supported in part by Ericsson under Grant MA-2020-003774, through Project 702C2000043 in part by R&D&I Support Program Line through the Junta de Andalucía (Andalusian Regional Government) in part by the Ministerio de Asuntos Económicos y Transformación Digital in part by European Union - NextGenerationEU, and in part by the Recuperación, Transformación y Resiliencia y elMecanismo de Recuperación y Resiliencia through Project MAORI
General correlation between R3 test results and compressive strengths for five families of supplementary cementitious material
Full text linkFunding for open access charge: Universidad de Málaga/CBUA.CSA Research LLC (USA) is thanked for funding I.K. PID2020-114650RB-I00 grant from Ministry of Science and Innovation of Spain, co-funded by ERDF, is thanked for partial financial support. Escuela de Ingenierías Industriales of Universidad of Málaga is thanked for providing the devices funded by Junta de Andalucía and ERDF (IE19_182 UMA grant) to perform the mechanical strength tests. The authors thank Ms. B. Guirado-Rodríguez, Ms. E. M. Benjumea-Rejano, and Mr. F. Gómez-García for assisting with some of the SAI tests.The incorporation of locally available supplementary cementitious materials (SCMs) in cement blends is essential for reducing the environmental impact of construction. However, assessing the pozzolanic kinetics, and thus the pozzolanic contribution at a given age, is challenging due to temperature differences between the two main evaluation methods: ASTM C1897 (40 °C, continuous heat release) and ASTM C311 (20 °C, Strength Activity Index at 28 days). This study examines 22 SCMs, analysing their composition, mineralogy, texture, and pozzolanic behaviour. ASTM C1897 was applied as prescribed, while ASTM C311 was modified by maintaining a constant water-to-binder ratio and introducing an additional 68 % PC–20 % SCM–10 % limestone–2 % gypsum series to better isolate pozzolan effects. The results confirmed established pozzolanic trends, with kaolinite-rich calcined clays ≳ silica fume > smectite-rich calcined clays > natural pozzolans ≳ class-F fly ashes. The modified series yielded clearer correlations, particularly between SAI2°C28d and Heat4°C3d, forming two well-defined clusters that reflect general behaviour. These findings suggest that the modified series could serve as a more reliable framework for future SAI evaluations. Moreover, for the 80 % PC–20 % SCM, the best correlation is found for the R3-heat release at 12 h (at 40 °C) and the SAI values at 28 days (at 20 °C). Additional insights into the pozzolanic kinetics and performance of the materials are also presented, contributing to a deeper understanding of their potential in sustainable construction practices
