Entrenamiento de la autoconfianza y control de la ansiedad en atletas de la categoría sub-16 de Bogotá D.C.
Authors: Marín Jarly , Gracia Álvaro
Published: July 2024

Introducción: Son diversas las habilidades psicológicas que se consideran fundamentales para predecir el rendimiento en el deporte tales como la autoconfianza, los niveles motivacionales, el control emocional o las estrategias de afrontamiento (Berenguiet, et al., 2012). Objetivo general: Identificar y elaborar un plan de entrenamiento psicológico que facilite la mejora de la autoconfianza y el control de la ansiedad mediante una regulación emocional adecuada ante la competición. Metodología: El enfoque es cuantitativo, porque, es explicita de manera numérica la magnitud y la cantidad de objetos de estudio investigados (Hernández, 2008). Diseño: Es experimental, de tipo transversal, con el manejo de variables independientes y dependientes (Hernández, et al., 2013). Alcance de la investigación: Exploratorio, porque se identificó poca información, se toma como un tema de estudio nuevo (Hernández, et al., 2013, p.72). Bases de datos: Las bases de datos utilizadas fueron 4; SportDiscus, Google Académico, ScienceDirect y ProQuest, en total fueron encontrados 81 artículos, de los cuales 14 fueron considerandos funcionales. Resultados: Fueron positivos, se logró evidenciar que los deportistas que fueron evaluados tienen niveles de ansiedad altos, momentos antes previos a la competencia y que su nivel de autoconfianza es bajo respecto a las capacidades con las que cuentan según los entrenamientos realizados durante esas semanas. Conclusiones: con el entrenamiento psicológico realizado durante estas semanas, se realizó de nuevo la prueba de PAR-P1, obteniendo resultados influyentes mejorando así sus niveles de ansiedad y su autoconfianza a la hora de competir.

Authors: Agudelo Carlos , González Luis
Published: July 2024

El objetivo fue investigar el efecto de dos planes de entrenamiento de la resistencia para patinadoras preadolescentes de Bello, uno continuo y otro discontinuo (intermitente) sobre el VO2Máx. Se contó con 17 sujetos así: 8 en el grupo intermitente (GE) y 9 en el grupo continuo (GC) (11,53±1,12 años; 147,8±6.56 cm. de talla; 40,3± 5.95 k. de peso y 4,3 años de experiencia deportiva), fueron distribuidos aleatoriamente en dos grupos experimentales. Ambos grupos experimentales entrenaron la resistencia durante 6 semanas con 3 estímulos por semana, uno de los grupos experimentales basó su entrenamiento en el método intermitente y el otro en el método continuo. Se trabajó por grupos contraste para medir la magnitud de los efectos. Se hallaron diferencias entre el pre-test y el pos-test para el grupo intermitente (p<0,1), no así para el continuo. Se concluyó que el entrenamiento de la resistencia basado en el método intermitente produjo diferencias importantes pero que no alcanzan a ser significativas estadísticamente (p<0,05) en el VO2Máx en patinadoras preadolescentes en los cambios que se producen en el VO2Máx.
Fracture Resistance and Failure Mode of Polyethylene Fiber-reinforced Resin-based Restorations in Structurally Compromised Premolars: an in Vitro Study
Authors: Canobra LF , Parra-Gatica E , Sanhueza V , Medina C , Wendler M
Published: July 2024

Objective:

To evaluate the effect of polyethylene fiber-reinforcement on the fracture resistance and fracture mode of extensive resin-based composite (RBC) restorations in structurally compromised maxillary premolars.

Methods and Materials:

Maxillary premolars (54) with specific dimensions and extracted for orthodontic reasons were used. Following mesio-occluso-distal (MOD) cavity preparation and endodontic access, teeth were randomly assigned to one of three restorative protocols (n=18): RBC applied incrementally (I) or reinforced with woven polyethylene fibers (Ribbond) placed horizontally (H) or U-shaped (U). Restored teeth were stored for 45 days in distilled water at 37°C and then loaded monotonically until fracture. Half of the specimens in each group received axial loading (A) and the other half was loaded paraxially (PA). Fracture load data was assessed using two-way analysis of variance and Tukey's post hoc test for multiple comparisons (α=0.05). The fracture initiation and propagation path were analyzed using stereomicroscopy and scanning-electron microscopy.

Results:

No significant differences were observed for the fracture strength among loading configurations, except for groups IA (825 N) and HA (553 N). Fracture initiated and propagated mainly at and through the RBC restoration in the I group, whereas a shift to the interface was observed in both polyethylene fiber-reinforced groups. Blocking and bridging of cracks were identified around the fibers, especially in specimens of group U.

Conclusions:

Incorporation of woven polyethylene fibers to reinforce extensive MOD resin-based composite restorations on endodontically treated premolars reduced the occurrence of cohesive fractures in the restorative material but was unable to increase the fracture resistance of the affected teeth.

Social Wellbeing and Community in the Processes of Musicking and Dance-Musicking: Investigating Students’ Social-Artistic Interactions
Authors: Kibirige Ronald
Published: July 2024

Social wellbeing is cultural-specific and largely dependent on phenomena surrounding a people. It is profoundly rooted in the understanding that the state of being healthy is achieved not only through medicalised treatment, but also in our daily community interactions. This chapter investigates the social-artistic interaction processes of musicking and dance-musicking, focusing on how they can facilitate, activate, and sustain students’ transformation from one state of being to another. It draws on social-artistic experiences in a community children’s ensemble in Uganda and focuses on detailed musical and body-rhythmic action, reaction and interaction that unfold in transcendental pedagogical moments of musicking and dance-musicking. As such, the discussion hinges on students’ embodied music and dance-music interaction in teaching and learning contexts. The chapter explores the concept of liminality and Ubuntu philosophy as theoretical frameworks, and adopts a combination of ethnographic and autoethnographic methods to investigate practical social-artistic experiences through which students achieve transformation to enter into a state of wellness in a social sense. From these experiences, I conceptualise a social-artistic model of a practitioner’s embodied state of being and transformation from one state of being to another. The broader aim of this study is to create an awareness of the multifaceted social benefits of the social-artistic interactive processes of musicking and dance-musicking that can activate and enhance students’ wellbeing in school environments.
Sangen og livet selv
Authors: Jenssen Runa Hestad
Published: July 2024

The encounter that occurs between the student and me when teaching voice is precious. Sometimes even magical. I am a soprano, teacher, and researcher in arts education who is passionate about caring for these precious voices. Teaching and researching voice are filled with great privilege and responsibility, because they offer an opportunity to take part in the student’s development – to be close to another being’s lived experience. And it is here the magic might occur. This chapter explores how dialogical vocal pedagogical entrances might be spaces for discovering and empowering voices in higher music education. Leaning on autoethnography as a method for my inquiry, I dive into and share my experiences as a voice teacher, where I critically examine and try to understand how master–apprentice pedagogy shapes the way I teach (and have been taught) voice. I ask, How might dialogical entrances to vocal pedagogical encounters create a diversity of voices in higher music education? To guide me in my critical investigation, I use the concepts of compassion and care as well as the philosophies of Paulo Freire to understand how critical explorations of life and pedagogical practices can allow educators and students to have greater awareness of their positions, create change in their practices, and experience well-being. My autoethnographic exploration seeks to illuminate dialogical entrances in vocal pedagogy as a space where voices can feel authenticity, be affirmed and empowered with a critical pedagogy as a pedagogy of love. Then, vocal pedagogical encounters might open for a multiplicity of voices in higher education, and be applicable in other pedagogical encounters, not only when teaching voice.
«Vi kunne bare slette opptaket og ta det opp på nytt igjen». Elevers erfaringer med å produsere podkaster i litteraturundervisningen på videregående
Authors: Schaik Gunvald van
Published: July 2024

Denne artikkelen belyser hvilke erfaringer elever gjør seg når de produserer podkaster i litteraturundervisningen på videregående. Studien bygger på åtte fokusgruppeintervjuer med elever i vg1 studiespesialiserende (N = 30). Analysene viser blant annet at elevene setter pris på å lage podkaster i litteraturundervisningen, at arbeidsmetoden legger godt til rette for samarbeid mellom elevene, og at podkast som vurderingsform kan bidra til økt variasjon i det muntlige vurderingsarbeidet. Elevene uttrykker også at det til tider var vanskelig å skape flyt i samtalene under innspilling, og poengterer at temaet samtidslyrikk var en av årsakene til dette. Funnene viser at elever har utbytte av å lage podkaster i litteraturundervisningen, og at arbeidsmetoden legger til rette for å arbeide systematisk med elevenes muntlige ferdigheter. 
ENGLISH ABSTRACT
“We could just erase and record again.” Upper secondary school students’ experiences of producing podcasts in their literature class
This article sheds light on upper secondary school students’ experiences of producing podcasts in their literature class. The study is based on eight focus group interviews (N = 30). The analysis shows that the students enjoy producing podcasts as a part of their literature class, that the method facilitates collaboration between them, and that student production of podcasts can contribute to increased variety regarding the forms of oral assessment in school. However, the students express that it sometimes was difficult to create a smooth conversation flow during their recordings, and that the topic of contemporary poetry was one of the reasons. The findings show that students can benefit from producing podcasts in their literature class, and that the method facilitates systematic work with students’ oral skills.

The Controversy Surrounding the Attempt to Publish the “Demons” Novel by F.M. Dostoevsky in 1935. Gorky’s Position
Authors: Yuriy Pushchaev
Published: July 2024

This article is a continuation of the article “Perception of the “Demons” Novel by F.M. Dostoevsky in Soviet Culture in the 1930s”. The main attention is paid to the controversy about the novel of the Soviet journalist and critic D.I. Zaslavsky, who opposed the publication of “Demons”, and the founder of socialist realism, the principle Soviet writer A.M. Gorky, who stood up for the publication. The article briefl y examines the history of Gorky's attitude towards Dostoevsky, the polemic that Gorky led against Dostoevsky throughout his creative life. The evolution of the studies and presentation of the “Gorky and Dostoevsky” issue in Soviet literary criticism is also briefl y considered with regard to the tendencies of philosophical and literary analysis of the correlation between the work o those writers depending on the ideological purpose and political situation in the country
Constancy and Breakthrough as Opposing Vectors of Empire Construction
Authors: Sergey Chernyakhovsky
Published: July 2024

In the present article the author addresses the issue of the correlation of the principles of constancy and breakthrough as dominant temperamental features of Russian pre-revolutionary and Soviet societies. Stating the formation in society of the attitude to the perception of national history in the unity of all its constituent historical periods, he draws attention to the need to realize their distinctive singularity, which makes it possible to understand the patterns of their change and comprehension of the qualities that make up their historical advantages and successes. From this point of view, the main difference between the Soviet society and the pre-revolutionary one is seen in the fact that the pre-revolutionary represented a kind of civilization and an empire of Permanence, whereas the Soviet, in contrast to it, was a civilization and an empire of Breakthrough. Attention is drawn to the fact that the preservation of the achievements accumulated during the Soviet period should be considered, fi rst of all, not as the preservation of its “Treasures” and riches, but as the preservation of the “Capital” of the Soviet era, in other words, such qualities of society that are capable of producing wealth, and in their functioning constantly expanded and reproduce them
Russian Transfi guration Notes on the Philosophy of History
Authors: Sergey Perevezentsev
Published: July 2024

Today we fi nd ourselves in a diffi cult situation trying to get out of the pit that we fell into a hundred years ago. Perhaps the last hundred years of Russian history were the lowest point of the metaphysical circle of history, a “failure” that led to unimaginable losses. But now we are slowly starting to get out of this “sinkhole”, climbing almost a sheer wall in order to restore our house somewhere up there on the plateau, which we once destroyed ourselves. So now we are seeking again the prospective Russia. And what do we think of this future Russia? Or more precisely, what do we expect her to be? The suggested answers to these questions differ completely. It seems that the image that could most fully express the meanings of the existence of Russian civilization in time and space, while connecting Russian present with Russian past and future, might be described as follows: “Transfi gured Russia” as the goal of our development, and “Russian Transfi guration” (another variant –“Transfi guration of Russia”), as the very process of achieving this goal. The “Russian Transfi guration” can be built only on the basis of creation, on establishing something new and better, on the pursuit of the ideal, and represent the process of gradual development-reforming the socio-economic, socio-political and cultural space of our country relying on Russian traditional values. Refl ections on these issues constitute the main content of these historiosophical notes

Synthetic dyes in wastewater from the textile industry pose a risk to the environment. These effluents can be treated with chemical and/or biological processes. The main problem can be the generation of toxic sludge, high operating costs or maintenance costs. Advanced oxidation pro-cesses show success with acceptable operating and maintenance costs. The aim of the work was to investigate the influence of reaction conditions on the decolourisation of simulated wastewater using the Fenton reagent in a batch system. The effectiveness was tested using the example of the anthraquinone colourant Acid violet 109. The influence of the initial concentrations of iron and hydrogen-peroxide in different molar ratios was tested.

PROSES KOGNITIF SISWA SEKOLAH DASAR DALAM MEMAHAMI MATERI PECAHAN DITINJAU DARI STIFIN FRAMEWORK: THINKING DAN FEELING
Authors: Kamid Kamid , Sutrisno Sutrisno , Anwar Khairul , Dewi Rina Kusuma
Published: July 2024

AbstractThe understanding of students, their learning methods, and cognitive characteristics are important aspects of classroom learning management. Fractional math problems require reasoning and mathematical logic, so to complete the gap in previous research, namely how types of intelligence form patterns of student thought processes, this study examines the level of student understanding and problem-solving strategies for fractions based on STIFin intelligence characteristics. This research uses a mixed-method approach in data collection. The research instrument uses the Fraction Sense Test (FST) and interviews and STIFin tests. The study involved 16 fourth-grade students of SD 47 Kota Jambi. The results showed that students with the thinking intelligence type scored the highest compared to sensing, intuiting, and feeling. Furthermore, there are four strategies students use in developing problem-solving strategies for fractions: (1) comparing fractions using other simple benchmark fractions like ½, (2) comparing fractions based on the denominator and numerator, (3) creating a fraction representation in the form of flat shapes to understand and compare fractions.

Published: July 2024

Math problem-solving skills among students are still lacking. This is demonstrated by kids' inability to comprehend inquiries, offer proper responses, or convey ideas. Low communication ability can also result from instruction that downplays the importance of students' ability to solve problems. This study aimed to determine whether the increase in the mathematical communication skills of students who received problem-based learning models was better than that of conventional learning. Moreover, to find out how students' attitudes toward problem-based learning models. This research method is quasi-experimental, and the research design is a Nonequivalent control group design. The experimental class gets learning with the problem-based learning model, and the control class with conventional learning. The population of this study was all students of class VII SMPN 2 Kota Mojokerto. The samples used were two classes of five selected by purposive sampling technique. To obtain research data, pretest, posttest, and mathematical communication skills were used using the independent sample t-test. Based on the results of data analysis, 1) improving students' mathematical communication ability using problem-based learning models is better than students using conventional learning; 2) students' attitude towards learning mathematics using the problem-based learning model is positive. Kemampuan siswa untuk memecahkan masalah matematika masih rendah. Hal ini ditandai dengan kurangnya siswa dalam memahami pertanyaan dan memberikan jawaban serta mengutarakan pikiran atau ide secara tepat. Rendahnya kemampuan komunikasi juga disebabkan oleh model pembelajaran yang belum menekankan siswa pada aspek pemecahan masalah.Tujuan penelitian ini adalah untuk mengetahui apakah peningkatan kemampuan komunikasi matematis siswa yang memperoleh model pembelajaran problem based learning lebih baik dari pada siswa yang menggunakan pembelajaran konvensional, dan untuk mengetahui bagaimana sikap siswa terhadap model pembelajaran problem based learning.

Sustainability Indicators of Foreign Assistance in the Field of Media and Information Literacy: A Case Study on Kyrgyzstan and Uzbekistan
Authors: DADAKHONOV Azamjon Oltmishevich ,   Johannes Gutenberg University of Mainz, Germany
Published: July 2024

Media and information literacy (MIL) projects are crucial for a country’s development. They provide citizens with access to vital information and resources. This enables them to learn about their rights and responsibilities, as well as gain access to critical resources to improve their quality of life. For the last decade several international organizations such as UNESCO, Internews, DW-Akademie annually have been providing grants for the training courses, and projects at various levels to increase the MIL level of the population in the Central Asian context. The present study will discuss ensuring the sustainability and efficiency of projects in the field of MIL in this region. The paper investigates the sustainability indicators of foreign aid initiatives in the realm of MIL within Central Asia. It aims to assess the long-term viability of foreign aid programs in fostering MIL across Central Asian nations through a comprehensive analysis of historical trends, policy frameworks, and stakeholder perspectives. As part of the research, face-to-face interviews were conducted with prominent trainers and experts from Kyrgyzstan and Uzbekistan. Emphasizing the role of public-private partnerships, technological integration, and cultural considerations, the paper explores avenues for promoting enduring change and enhancing the effectiveness of foreign assistance in this critical field. The findings contribute valuable insights to policymakers, practitioners, and scholars interested in optimizing foreign aid strategies for sustainable development in the ever-evolving landscape of media and information literacy in Central Asia.
Ownership Structure and Firm Performance. A Panel Regression Study from Poland
Authors: Gryko Andrzej , Cierocki Jakub , Celer Konrad
Published: July 2024

This paper explores the relationship between ownership structure and firm performance, using the framework of agency theory. Given a sample of 126 Polish non-financial firms listed on the Warsaw Stock Exchange between 2016-2021, we applied fixed and random effects panel regressions with robust standard errors, tested for specification, endogeneity, cross-sectional heteroskedasticity, and serial autocorrelation. Our models identify several significant associations of adopted ownership structures with firm performance measured by accounting and market-based measures. We find that ownership concentration by the largest shareholder is negatively related to enterprise market-measured performance. Additionally, our results indicate the significance of shareholder heterogeneity.
Derecho de desistimiento y faltas informativas relativas al precio
Authors: Arnau Raventós Lídia
Published: July 2024

El comentario que sigue se inspira en la STJUE 5.10.2023, Sofatutor, relativa a un contrato de servicios celebrado electrónicamente. El TJUE resuelve que si, al contratar, no se informa al consumidor que, tras un primer período de prestación gratuita de los servicios, el contrato deviene oneroso y prorrogable, sin informar tampoco el precio, entonces procede reconocerle una segunda facultad de desistir del contrato ya oneroso. El estudio analiza de qué modo las faltas informativas acaban incidiendo en la disciplina del derecho a desistir. Y se presta especial atención al deber precontractual y pericontractual de informar, en concreto, acerca del precio a efectos de determinar cómo repercute su infracción en la eficaz perfección del contrato (art. 6.1, letra e y art. 8.2.I DDC). A propósito de la contratación a través de medios electrónicos, la conclusión que se alcanza es que sólo impide que el consumidor quede obligado el no haber articulado el proceso de contratación de tal manera que sea imprescindible, para dicho consumidor, confirmar expresamente que es conocedor de la naturaleza onerosa del contrato (art. 8.2.II DDC). La eficacia contractual se vincula, pues, a la expresión de conocimiento de la causa onerosa pero no, necesariamente, a la información o conocimiento relativos al precio. Si aquella eficacia contractual no se produce y, por ello, el consumidor no queda obligado contractualmente, es innecesario atribuirle la facultad de desistimiento porque no hay nada de lo que desistir.

This study aims to reflect on the importance of data protection law, namely the General Data Protection Regulation (GDPR), when it comes to International Arbitration, which is something that implies the need to articulate different laws and international treaties. For this reason, we address the different issues regarding the material and territorial scope of the regulation, as well as the question of transfers of personal data to third countries. We also analyze which personal data can be processed during an international arbitration. Finally, our investigation takes into consideration some of the main issues regarding the proceeding of arbitration itself and evaluates whether the GDPR can offer, when applicable, a coherent answer to the data protection’s issues emerging in international arbitration. In a world more technologic than ever, this study aims to demonstrate how these two different worlds (data protection law and international arbitration) can collide for a common application whenever it is necessary.
“Pay or ok”. Pagar con datos personales tras la Directiva 2019/770
Authors: Castillo Parrilla José Antonio , Morais Carvalho Jorge
Published: July 2024

Partiendo de las ideas de onerosidad, precio y contraprestación en la teoría general de las obligaciones y de los contratos, se analiza en este texto la cuestión del pago con datos personales en los contratos celebrados con consumidores frente a los ordenamientos jurídicos español y portugués. A pesar del temor del legislador a utilizar la palabra “contraprestación” en este contexto, se argumenta que estamos ante un pago con datos personales siempre que se cumplan tres supuestos: (i) el tratamiento de datos se basa en el consentimiento del interesado (consumidor); (ii) el profesional responsable del tratamiento está vinculado por el consentimiento del consumidor (interesado) de tal forma que se produce el sinalagma do (res) ut des (data); (iii) la responsabilidad del consumidor es consecuencia de la libertad de consentimiento. De este último aspecto se desprende que la mera restitución recíproca de prestaciones no puede considerarse un perjuicio para la revocación del consentimiento.
Análise da Resolução do Parlamento Europeu, de 20 de Outubro de 2020, e da Proposta de Directiva do Parlamento Europeu e do Conselho relativa à adaptação das regras de responsabilidade civil extracontratual à inteligência artificial (Directiva Responsabilidade Civil em Matéria de IA)

Procede-se, neste estudo, à análise da Resolução do Parlamento Europeu, de 20 de Outubro de 2020, e da Proposta de Directiva do Parlamento Europeu e do Conselho relativa à adaptação das regras de responsabilidade civil extracontratual à inteligência artificial (Directiva Responsabilidade Civil em matéria de IA). Ambas representam o esforço encetado pelo legislador europeu de ajustar os requisitos e os encargos probatórios tipicamente associados às acções de responsabilidade civil extracontratual à nova realidade da inteligência artificial. Todavia, os documentos não adoptam soluções iguais: se a Resolução se aproxima de um regime de responsabilidade objectiva, coadjuvado por um sistema de socialização do risco baseado na celebração de seguros e na existência de um fundo de garantia, a Proposta de Directiva assenta essencialmente no regime comum da responsabilidade civil subjectiva, fazendo-lhe ligeiras alterações ao nível da prova. Ao longo do artigo, os textos são comparados com apoio na mais moderna doutrina nacional (e também em alguma literatura estrangeira). No final, apresentam-se as posições de diferentes autores e perfila-se aquela que considera que a orientação da Resolução seria a mais adequada e justa.

Published: July 2024

Perusahaan perlu berhati-hati saat menentukan jumlah produksi botol minuman kemasan. Jumlah persediaan bahan baku dan permintaan menjadi faktor penting dalam menentukan jumlah produksi. Ketidakpastian jumlah permintaan produk minuman mengakibatkan jumlah produksi botol kemasan minuman kurang selaras dengan jumlah persediaan bahan baku minuman dan jumlah permintaan produksi botol kemasan. Adanya faktor ketidakpastian jumlah permintaan menjadikan pentingnya pemilihan metode peramalan yang tepat untuk memprediksi jumlah permintaan berdasarkan data historis. Penelitian ini bertujuan melakukan studi penentuan jumlah produksi botol kemasan minuman yang optimal dengan mempertimbangkan faktor ketidakpastian. Metode Fuzzy Time Series Markov Chain (FTSMC) adalah satu salah metode peramalan berbasis time series dan dapat diterapkan pada permasalahan ketidakpastian peramalan yang terjadi. Hasil peramalan, setelah melalui uji verifikasi menjadi input metode Fuzzy Inference System (FIS) untuk menentukan jumlah produksi botol minuman agar bersesuaian dengan jumlah permintaan dan jumlah bahan baku. Model FIS yang dibangun pada penelitian ini adalah Fuzzy Sugeno dan Fuzzy Mamdani. Untuk mengetahui metode yang memberikan hasil yang optimal pada permasalahan ini, kedua model yang dibangun tersebut dianalisis dengan membandingkan nilai Mean Absolute Percentage Error (MAPE). Hasil penelitian menunjukkan bahwa kedua model, yatu model FTSMC Fuzzy Mamdani dan model FTSMC Fuzzy Sugeno mampu memberikan solusi optimal.
