Influencia del uso de redes sociales en el sueño, el rendimiento académico y la actividad física en estudiantes de Secundaria
Authors: Rojí Morcillo Guillermo 
Published: December 2024

This study examines the impact of social media use on sleep quality, academic performance, and physical activity in 3ºESO students at a high school in Caravaca de la Cruz, Murcia. The relationships between the use of various social media platforms and these factors were evaluated. The results revealed moderate and significant negative correlations between intensive use of Instagram, TikTok, and BeReal, and both sleep quality and academic performance. Students who used these social networks more frequently showed a higher likelihood of experiencing sleep problems and lower academic performance compared to those who limited their use. The conclusions highlight the importance of taking steps to manage excessive social media use during adolescence. This includes not only raising awareness of its adverse effects but also developing educational programs and family strategies that foster more conscious and balanced use. Promoting healthy digital habits mitigate the negative impact on sleep and academic performance.
Este estudio analiza el impacto del uso de redes sociales sobre la calidad del sueño, el rendimiento académico y la actividad física en estudiantes de 3º de Educación Secundaria Obligatoria (ESO) en un centro educativo de Caravaca de la Cruz, Murcia. Se evaluaron las relaciones entre el uso de diversas plataformas sociales y los aspectos mencionados. Los resultados revelaron correlaciones negativas moderadas y significativas entre el uso intensivo de Instagram, TikTok y BeReal, y, tanto la calidad del sueño como el rendimiento académico. Los estudiantes que utilizaban estas redes sociales de manera más frecuente mostraron una mayor probabilidad de sufrir problemas de sueño y un rendimiento académico más bajo en comparación con aquellos que limitaban su uso. Las conclusiones subrayan la importancia de tomar medidas para gestionar el uso excesivo de redes sociales en la adolescencia. Esto implica no solo la concienciación sobre sus efectos adversos, sino también el desarrollo de programas educativos y estrategias familiares que fomenten un uso más consciente y equilibrado. Promover hábitos digitales saludables reduciría el impacto negativo en el sueño y el rendimiento académico.

Published: December 2024

В работе проводится анализ ценообразующих факторов, влияющих на стоимость кофемашин. На первом этапе работы составляется база исходной информации, при формировании которой в качестве экзогенных факторов были выбраны такие параметры кофемашин как тип прибора, его габариты, мощность, объем и виды приготовляемого кофе, а также отзывы потребителей о работе и качестве рассматриваемой кофемашины. Источником информации послужил интернет-магазин Wildberries. На следующем этапе работы проводится корреляционный анализ влияния экзогенных переменных на стоимость кофемашин, показавший, что в целом стоимость формируется на основе габаритов и мощности прибора. Далее был проведен регрессионный анализ, позволивший построить модель оценки стоимости кофемашин. На следующем этапе работы были построены отдельные модели по разным типам кофемашин, позволившие более детально увидеть процесс ценообразования для разных групп приборов. На заключительном этапе был проведен сравнительный анализ работы построенных моделей на примере оценки конкретных кофемашин.
In the paper, the author analyzes the pricing factors influencing the cost of coffee machines. At the first stage of the work, the author compiled a database of initial information, in the formation of which, as exogenous factors, the author chose such parameters of coffee machines as the type of device, its dimensions, power, volume and types of coffee prepared, as well as consumer reviews about the operation and quality of the coffee machine in question. The source of information was the Wildberries online store. At the next stage of the work, the author conducts a correlation analysis of the influence of exogenous variables on the cost of coffee machines, which showed that in general the cost is formed on the basis of the dimensions and power of the device. Next, the author conducted a regression analysis, which allowed him to build a model for assessing the cost of coffee machines. At the next stage of work, the author built separate models for different types of coffee machines, which made it possible to see in more detail the pricing process for different groups of devices. At the final stage, the author conducted a comparative analysis of the work of the constructed models using the example of evaluating specific coffee machines.

Published: December 2024

Este artigo pretende discutir os impactos do abuso sexual no desenvolvimento e na manutenção de relacionamentos afetivos, a partir de uma revisão bibliográfica. O abuso sexual, definido como uma forma de violência que envolve atos de cunho sexual perpetrados por um agressor psicologicamente mais desenvolvido do que a vítima, é amplamente reconhecido como um grave problema de saúde pública. As consequências desse tipo de violência são profundas e duradouras, comprometendo a capacidade da vítima de estabelecer e manter relações afetivas saudáveis. A pesquisa foi motivada pela necessidade de compreender como essas cicatrizes emocionais e psicológicas, resultantes do abuso sexual, manifestam-se nos relacionamentos futuros. Para alcançar esse objetivo, foram analisados diversos estudos e literaturas especializadas, que abordam as consequências psicológicas do abuso sexual em vítimas durante sua vida adulta. Os resultados indicaram que o abuso sexual tem um impacto significativo na percepção da vítima sobre afeto e intimidade, frequentemente resultando em dificuldades para estabelecer vínculos afetivos seguros. Conclui-se que a terapia psicológica, fundamentada em abordagens como a psicanálise, é crucial para a reestruturação emocional das vítimas, proporcionando-lhes ferramentas para reconstruir sua capacidade de formar relacionamentos saudáveis. Essas conclusões reforçam a importância de intervenções terapêuticas precoces e contínuas no tratamento de vítimas de abuso sexual, visando minimizar os impactos negativos em seus relacionamentos afetivos futuros.
La transition vers les études postsecondaires : point de vue d’étudiante·s collégien·ne·s et universitaires ayant un TDAH

Published: December 2024

Chez les étudiant⋅e⋅s ayant un trouble de déficit de l’attention/hyperactivité (TDAH), l’adaptation au contexte d’études postsecondaires comporte des défis supplémentaires par rapport à leurs pairs sans cette condition. Cet article présente les résultats d’une étude qualitative exploratoire visant à décrire l’expérience de la transition chez cette population étudiante au Québec. Des entretiens semi-dirigés ont été menés auprès de 29 étudiant⋅e⋅s ayant un TDAH provenant d’un cégep (n = 10) ou d’une université (n = 19). Les participant⋅e⋅s ont rapporté de nombreux défis liés notamment au nouvel environnement scolaire et aux exigences pédagogiques élevées, ainsi que des facteurs ayant facilité leur adaptation (soutien des proches, acceptation du TDAH). De plus, l’adaptation au contexte collégial semble davantage avoir été une période exigeante et déstabilisante, en comparaison avec le contexte universitaire. Les résultats offrent des cibles d’intervention pour préparer et soutenir ces étudiant⋅e⋅s à la transition.
¿Por qué justificamos la evasión fiscal? Evidencia empírica a partir de una encuesta factorial en España
Authors: Bartolomé Peral Edurne , Dülmer Hermann , Coromina Lluís 
Published: December 2024

Los Estados están obligados a recaudar fondos para financiar bienes y servicios públicos. Al reducir la renta disponible de los contribuyentes, estos impuestos representan cargas que los individuos intentan reducir. El modelo económico estándar explica la evasión fiscal en función de probabilidades de inspección, riesgo, sanciones, tipos impositivos y renta. Sin embargo, el cumplimiento es mayor que el previsto en este modelo. Para resolver este puzle, la literatura distingue entre cumplimiento coercitivo (modelo económico estándar) y cumplimiento voluntario (modelo basado en legitimidad). Estos y otros elementos se analizan en una encuesta factorial realizada en 2017 a ciudadanos españoles con el objetivo de identificar qué factores influyen en la justificación de la evasión fiscal. Entre los factores situacionales, la renta familiar bruta y el nivel de corrupción del país fueron los que más influyeron en la justificación de la evasión fiscal. Al nivel de los encuestados, el análisis multinivel confirmó que las cohortes de mayor edad, las personas con mayor nivel educativo y los encuestados que creían en principios morales básicos justificaban mucho menos la evasión fiscal. Por lo tanto, nuestro estudio confirma que el cumplimiento de las obligaciones fiscales va más allá del mero cálculo de las ganancias y pérdidas materiales personales. Una implicación práctica es que el Estado debería esforzarse cada vez más por ejercer la transparencia y transmitir eficazmente a los ciudadanos que el uso de los impuestos es justo, equitativo y libre de corrupción.
Mütoloogiline tegelane tšokmor udmurtide traditsioonilises maailmavaates
Authors:   Institute of Udmurt Philology, Finno-Ugric Studies and Journalism, Udmurt State University, Russia, Gluhhova Galina 
Published: December 2024

Based on linguistic data and ritual practices of the Udmurts, the article explores the etymology of the word chokmor. The analysed material indicates that the term chokmor/chokmorskon is used in the local traditions of both southern (Kiyasovo district) and northern (Kez district) Udmurts during winter and spring-summer ceremonies. The study of the term chokmor in the traditional worldview of the Udmurts allows for the hypothesis that the word is derived from the term chek or cheke, and in this context, in the rituals of commemoration, it serves as a symbol of contact with the otherworldly realm. In the rituals of spring and winter masquerades, it personifies the soul of a deceased ancestor, “appearing” in this world in the form of a masqueraded character.

Published: December 2024

O presente texto é resultado de diálogos com diferentes segmentos sociais que se preocupam cotidianamente com o expressivo quantitativo de barramentos existentes em municípios baianos a exemplo da porção alta da bacia hidrográfica do rio Paraguaçu onde se encontra o polo agrícola da Chapada Diamantina. O estudo foi norteado no o Relatório de Segurança de Barragens (RSB) da Agência Nacional de Águas - ANA, ano 2018, e teve como objetivo relacionar os dez municípios da Bahia que mais possuíam barragens naquele ano e, identificar as categorias de riscos, os danos potenciais associados e modos de usos dessas barragens; com os resultados, verificou-se que tanto o critério categoria de risco quanto o dano potencial associado são preocupantes, uma vez que a classificação (alta) predomina em mais de cinquenta por cento (50%) dos empreendimentos cadastrados até o ano (2018). Sobre os modos de usos, a irrigação predomina entre os três municípios baianos que mais possuem barragens cadastradas (Mucugê, Ibicoara e Juazeiro), situação que já se caracteriza como conflituosa em diferentes espaços nesses municípios uma vez que, nos períodos de estiagens prolongadas a oferta de água está se tornando cada vez mais escassa para os pequenos e médios produtores de alimentos.

Das neue Recht auf Reparatur – Was ändert sich im digitalen Verbrauchergewährleistungsrecht? — Ein Überblick zu Voraussetzungen und Umfang des Rechts auf Reparatur und zum Pflichtenkreis für Hersteller
Authors: Kapoor Arun , Leucuta David 
Published: December 2024

Zusammenfassung
Der Elektroschrott in Europa nimmt stetig zu, während gleichzeitig nach wie vor wenig davon recycelt wird. Und das, obwohl scheinbar ein Großteil der Verbraucher mangelhafte Waren lieber reparieren würde, als neue zu kaufen. In diesem Kontext wurde am 10.7.2024 im Amtsblatt der Europäischen Union die Richtlinie (EU) 2024/1799 über gemeinsame Vorschriften zur Förderung der Reparatur von Waren und zur punktuellen Änderung des Verbraucherschutzrechts veröffentlicht. Dieser Beitrag beleuchtet den Regelungsgehalt der neuen „Recht auf Reparatur“- Richtlinie, wobei ein Hauptaugenmerk darauf liegt, welche Änderungen im digitalen Verbrauchergewährleistungsrecht vorgenommen werden sollen.

Eigenbedarf: Die sog. Vorratskündigung des Vermieters
Authors: Adam Roman F. 
Published: December 2024

Zusammenfassung
In sämtlichen Rechtsgebieten entspricht es allgemeiner Meinung, dass keine Kündigung „auf Vorrat“ erklärt werden darf, d. h. gewartet werden muss, bis ein Grund zur Beendigung von Vertragsverhältnissen tatsächlich vorliegt, wobei vor allem der sog. Vorratskündigung wegen Eigenbedarfs des Vermieters erhebliche Bedeutung zukommt; häufig ist die Bewertung der zugrunde liegenden Umstände, insbesondere im Hinblick auf den Bedarfszeitpunkt und die Eintrittsprognose mit Schwierigkeiten verbunden. Der folgende Beitrag befasst sich zunächst mit verschiedenen Fallgruppen einer unwirksamen Eigenbedarfskündigung, um sich danach ausführlich der sog. Vorratskündigung zu widmen.

Der Beitrag kommt zu dem Ergebnis, dass der BFH entgegen der EuGH-Rechtsprechung in der zollamtlichen Überlassung einer Nicht-Unionsware zum zollrechtlich freien Verkehr gem. Art. 201 UZK einen Einfuhrumsatz und in der Steuerbefreiung des § 5 Abs. 1 Nr. 3 UStG einen unselbstständigen Bestandteil dieses Zollverfahrens sieht.
Bridged Azobenzenes and Their Chemical Applications
Authors: Warner David J. , Keane Katie S. , Blackstock Silas C. 
Published: August 2019

Abstract
The ability of azobenzene and its derivatives to undergo reversible and rapid light‐induced isomerization has led to its incorporation in a wide variety of chemical systems that are photoswitchable between two or more states. Following a brief introduction to azobenzene properties and a section describing new methods for azobenzene switching, this chapter summarizes selected recent reports on a wide range of chemical applications of bridged azobenzene. New switchable materials and their applications include molecular machines, triggered catalysis, porous metal‐organic structures, phase‐change materials, and responsive surfaces. The chapter describes how researchers have tailored the azobenzene function and its environment to fine‐tune absorption characteristics, photophysics, isomerization dynamics, and energetics to enhance function. Collectively, the works reported in this chapter illustrate the broad utility of photochemical and molecular control of function afforded by the cis–trans isomerization of azobenzene.
The contagious impact of playing violent video games on aggression: Longitudinal evidence
Authors: Greitemeyer Tobias 
Published: August 2019

AbstractMeta‐analyses have shown that violent video game play increases aggression in the player. The present research suggests that violent video game play also affects individuals with whom the player is connected. A longitudinal study (N = 980) asked participants to report on their amount of violent video game play and level of aggression as well as how they perceive their friends and examined the association between the participant's aggression and their friends’ amount of violent video game play. As hypothesized, friends’ amount of violent video game play at Time 1 was associated with the participant's aggression at Time 2 even when controlling for the impact of the participant's aggression at Time 1. Mediation analyses showed that friends’ aggression at Time 1 accounted for the impact of friends’ amount of violent video game play at Time 1 on the participant's aggression at Time 2. These findings suggest that increased aggression in video game players has an impact on the player's social network.
Photopatternable Nanolayered Polymeric Films with Fast Tunable Color Responses Triggered by Humidity

Published: August 2019

AbstractSmart surfaces that can dynamically respond to environmental stimuli have demonstrated great promise in wearable electronics and optical detectors. Herein, a photopatternable nanolayered polymeric film that can reversibly display and hide structural colors in the visible range in response to relative humidity (RH) changes is reported. This film is fabricated on a silicon substrate using layer‐by‐layer assembly of chitosan and photoreactive carboxymethyl cellulose‐azido derivative, and selectively crosslinked through UV irradiation from a photomask. Compared to crosslinked regions, un‐crosslinked ones swell more and result in a larger thickness at high RH; as a result, those two regions show distinguishable color differences. The correlation of displayed color with film thickness at various RHs is plotted in an International Commission on Illumination (CIE) chromaticity diagram, which is in good agreement with the results obtained from modeling based on the interference theory. It is demonstrated that the structural color patterns on the film can be hidden and displayed spontaneously by contact with humid air, including human breath. This humidity‐triggered color change is fast, of fine resolution, highly reversible, and compatible with most silicon‐based devices. This film is low‐cost, stable, and ready to be applied to large surface areas for potential applications in anticounterfeiting, humidity sensors, and optical color filters.

Published: August 2019

AbstractTo realize highly efficient neuromorphic computing that is comparable to biological counterparts, bioinspired computing systems, consisting of biorealistic artificial synapses and neurons, are developed with memristive devices with native dynamics resembling biological synapses and neurons. Tremendous materials and devices have been successfully used to emulate diverse functions of synapses, as well as neurons, in the last decade. Herein, approaches to realize certain synaptic or neuronal functions are introduced with state‐of‐art experimental demonstrations. First, the dynamics and working principles of biological synapses and neurons are briefly presented to provide guidance for developing biorealistic synapses and neurons. Second, recent advances in the development of memristive synapses with homosynaptic and heterosynaptic plasticity are disscussed. In particular, approaches to realize the important learning rules, like spiking‐timing‐dependent plasticity and Bienenstock–Cooper–Munro learning rules, are elaborated according to the level of faithfulness to biological synapses. Memristive neurons, including bioplausible neurons and biophysical neurons, are described. Finally, challenges and perspectives for bioinspired computing based on memristive devices are briefly discussed.
Balanced Performance Enhancements of a‐InGaZnO Thin Film Transistors by Using All‐Amorphous Dielectric Multilayers Sandwiching High‐k CaCu3Ti4O12

Published: August 2019

AbstractThe requirements of low power consumption and fast operation have necessitated the development of thin film transistors (TFTs) with exploration of new dielectric materials. Here, the unprecedented integration of high‐κ dielectric CaCu3Ti4O12 is reported, yielding significant enhancements in the performance of amorphous InGaZnO TFTs. Using a multilayer structured amorphous Al2O3/CaCu3Ti4O12/Al2O3 dielectric configuration, the performance of the transistors is greatly improved as highlighted with high saturation mobility (>10 cm2 Vs−1), high on/off current ratio (3.8 × 107), low threshold voltage (≈0.51 V), and low subthreshold swing (≈0.45 V decade−1). The balanced performance enhancements are attributed to the lower density of interfacial/bulk trap states and sufficient band offsets.

Published: August 2019

AbstractCarbon dioxide (CO2) is one of the end products of fuel combustion and the major component of the greenhouse gases. The reduction of atmospheric CO2 not only decreases environmental pollution but also produces value‐added chemicals, solving energy and environment issues simultaneously. One significant challenge is the low conversion efficiency of CO2 reduction due to the inertness of the CO2 molecule. The design of the catalyst nanomaterials with the high selectivity, stability, and the activation capabilities for the conversion of CO2 is needed. Atomic layer deposition (ALD), capable of constructing catalysts with atomic‐level precision in a highly controllable manner, is a promising technique to address the key problems in CO2 reduction. This review explores the application of ALD in CO2 reduction, emphasizing the designs of the efficient catalyst nanomaterials fabricated by the ALD technique and their applications in CO2 reduction and capture. The significance of the ALD catalysts with the fine structures is highlighted to obtain a better understanding of the catalytic performance–aimed benefits as well as an outlook on the ALD‐designed catalysts for the reduction of CO2.
