Published: September 2021

Debris flow is a disaster occurring in cases where a sediment particle flows at high speed, down to the slope, and usually with high viscosity and speed. This disaster is very destructive and human life-threatening, especially in mountainous areas. As one of the world’s active volcanoes in the world, Rinjani had the capacity to produce over 3 million m3 volume material in the 2015 eruption alone. Therefore, this study proposes a numerical model analysis to predict the debris flow release area (erosion) and deposition, as well as the discharge, flow height, and velocity. The Digital Elevation Model (DEM) was analyzed in ArcGIS, to acquire the Cartesian coordinates and “hillshade” form. This was also used as a method to produce vulnerable areas in the Jangkok watershed. Meanwhile, the Rapid Mass Movement Simulation (RAMSS) numerical modeling was simulated using certain parameters including volume, friction, and density, derived from the DEM analysis results and assumptions from similar historical events considered as the best-fit rheology. In this study, the release volume was varied at 1,000,000 m3, 2,000,000 m3, and 3,000,000 m3, while the simulation results show movement, erosion, and debris flow deposition in Jangkok watershed. This study is bound to be very useful in mitigating debris flow as disaster anticipation and is also expected to increase community awareness, as well as provide a reference for structural requirements, as a debris flow prevention.

Maintaining Middle School Students’ Engagement in Virtual Learning Environments
Authors: Ibarra Blanca , Lu Pierre
Published: September 2021

The current COVID-19 pandemic has created many challenges for teachers as they transition to teaching in virtual learning environments. Virtual learning environments have forced educators to adapt teaching strategies and become creative and innovative to maintain student engagement (Korkmaz & Toraman, 2020). Middle school social studies teachers have always dealt with a lack of student interest in learning history, and the current instructional setting is requiring a reimagined teacher craft to deliver high-quality instruction. The interaction between students and teachers often depends on the content, highly effective questioning, choice in response methods, technology tools, or learning platforms (Czerkawski & Lyman, 2016). A conceptual understanding of the types of engagement, including cognitive, affective, and behavioral (Buric & Franzel, 2020; Raes, Vanneste, Pieters, Windey, Van Den Noortgate & Depaepe, 2020; Van Uden, Ritzen & Pieters, 2013; Ding, Kim & Orey, 2017) will help inform the types of instructional strategies that will be most effective at increasing and maintaining student engagement. The purpose of this phenomenological study was to describe the experiences and problems associated with engaging students in virtual learning environments for middle school social studies teachers in a border school district with over 40,000 students. The overarching theme that emerged from the data collected was that teachers play a significant role in creating a learning environment that supports students, encourages participation through interactive technology, and nurtures relationships to promote student engagement. Findings suggest educators understand the challenges educators face to keep students engaged and motivated, and some of the best practices that can increase student engagement in virtual learning.

Authors: Sisodiya Kushagra Singh
Published: September 2021

Abstract: The Industrial Revolution 4.0 has flooded the virtual world with data, which includes Internet of Things (IoT) data, mobile data, cybersecurity data, business data, social networks, including health data. To analyse this data efficiently and create related efficient and streamlined applications, expertise in artificial intelligence specifically machine learning (ML), is required. This field makes use of a variety of machine learning methods, including supervised, unsupervised, semi-supervised, and reinforcement. Additionally, deep learning, which is a subset of a larger range of machine learning techniques, is capable of effectively analysing vast amounts of data. Machine learning is a broad term that encompasses a number of methods used to extract information from data. These methods may allow the rapid translation of massive real-world information into applications that assist patients and providers in making decisions. The objective of this literature review was to find observational studies that utilised machine learning to enhance patient-provider decision-making utilising secondary data.

Indonesia’s capital city relocation: A perspective of regional planning
Authors: Farida Farida
Published: September 2021

The role of a capital city is essential for a nation. Indonesia’s plan to relocate its capital from Jakarta to North Penajam Paser has been set in stone. The Indonesian government targets the relocation to be executed in 2024; therefore, the preparations and capital city development must start from 2020. This research aims to study capital relocation from the perspective of regional planning concerning institutional, spatial planning, the economy, social aspects, and the environment. The data source used in this research was the secondary data obtained from literature review and document analysis. The new capital must present a distinct identity, as it will determine the institutional that will lead to success. The main reasons for the capital relocation are growth and economic equality for the eastern part of Indonesia. It means that development will be encouraged to achieve these goals. On the other hand, overly rapid development in the new capital is also undesirable—a challenging paradox for the institutions involved that demands creativity and innovation for a successful capital relocation.
Study of fiscal decentralization, macroeconomic stability and regional growth in Indonesia
Authors: Haryanto Joko Tri , Tenrini Rita Helbra
Published: September 2021

Indonesia has been implementing fiscal decentralization since 2001. In theory, fiscal decentralization affected macroeconomic stability and economic growth—this study using data panels at the provincial level from 2010 to 2013. In the relationship between fiscal decentralization and macroeconomic stability with control variable income, significant variables are income to GRDP, GRDP per capita, and population. If control variable expenditure, significant variables are expenditure to GRDP, GRDP per capita, and population. In the model that analyzes fiscal decentralization and economic growth with control variable income, significant variables are income to GRDP, consumption to GRDP, and population. Meanwhile, if control variable expenditure, significant variables are expenditure to GRDP, consumption to GRDP, and population. By using sensitivity analysis, the population variable is a high priority. Therefore stakeholders should treat population variables carefully.
A quem pertence a universalidade? O Patrimônio e o Museu à luz da Teoria Pós-Colonial
Authors: Pimenta Bueno Mariana
Published: September 2021

Diante dos crescentes debates sobre repatriação museológica e a reticência de museus europeus quanto a isso, esta pesquisa tem como objetivo analisar criticamente através da Teoria Pós-Colonial, e por meio da análise de documentos, a suposta universalidade do patrimônio anunciada na Declaration on the importance and value of universal museums, lançada em 2002. Questionando esta característica proposta pelos museus signatários, pergunta-se: seria a conservação do patrimônio um valor ocidental? Posto isto, a hipótese testada é que o documento em questão é uma invocação à manutenção colonial ocidental. Composto por três seções, o artigo apresenta conceitos inseridos no museu, como memória e patrimônio, para compreender como seus significados estão intimamente ligados ao Eurocentrismo, através de normas referentes ao espaço e que podem ser exemplificadas pelo documento previamente citado. Ademais, são utilizadas recomendações feitas pela UNESCO a fim de explicar como a universalidade da normatização patrimonial e museológica é validada por esses espaços ocidentais, assim como analisar os pedidos de repatriação de peças museológicas como um desafio ao sistema internacional. Por fim, o objetivo aqui proposto não é apresentar uma resposta final a esta agenda, mas sim trazer à luz e problematizar, dentro da área de Relações Internacionais, a importância deste debate.

Authors: Ticks Luciane Kirchhof , Hartemink Patricia Streppel
Published: September 2021

Esta pesquisa tem como objetivo analisar o discurso de uma professora de língua inglesa, a fim de identificar como estão materializadas léxico-gramaticalmente as ações dialógicas e monológicas, por ela adotadas, durante o desenvolvimento de uma aula da modalidade do Ensino de Jovens e Adultos (EJA). Para analisar os dados, adotamos uma abordagem híbrida, fundamentada pelo conceito de dialogismo (BAKHTIN, 1981, 1986; SCOTT; MORTIMER; AGUIAR, 2005), procurando depreender as ações monológicas e dialógicas subjacentes ao discurso dessa professora, e salientando como essas ações são constituídas por significados ideacionais e interpessoais, com base na Linguística Sistêmico-Funcional (HALLIDAY; MATTHIESSEN, 2014; FUZER; CABRAL, 2014). A análise revelou que a professora equilibra ações discursivas: a) monológicas (11 ocorrências), caracterizadas por restrições à mediação, materializadas pelo uso de declarações e de processos verbais e relacionais; b) dialógicas (11 ocorrências), ao dar voz aos alunos, por meio de perguntas, materializadas por processos mentais, as quais os levam à reflexão sobre os temas abordados.

Neste artigo, analisamos as crenças de alunos, entre 9 e 10 anos, sobre seus entendimentos do que seria um bom professor de inglês no contexto educacional no qual estão inseridos, a saber, o Programa Bilíngue em língua inglesa, de uma escola da rede particular de ensino, localizada em um município do Estado do Rio de Janeiro. Construímos a arquitetura teórica fundamentadas na Linguística Sistêmico-Funcional, em seu sistema de avaliatividade, enfocando a perspectiva social dos estudos de crenças no ensino de línguas. Inspiradas pela pesquisa do praticante, que se alinha ao paradigma qualitativo, duas atividades pedagógicas foram propostas, gerando reflexões sobre o tema. Conversas entre os participantes foram gravadas e transcritas para a sua análise microdiscursiva, quando investigamos os recursos linguísticos avaliativos, bem como a sua correlação com a construção das crenças. Nossos entendimentos sugerem que as crenças emergem de avaliações de afeto e de julgamento e relacionam-se à experiência profissional do professor, ao seu domínio do idioma e à importância do lúdico na formação do aluno.

Is a Foundation Year Programme to an A-Level as a 7-UP is to a Sprite: Exploring an Attempt to Diversify an English University
Authors: Anyadike-Danes Chima Michael
Published: September 2021

What contribution might social anthropology make to our understanding of the consequences of successive British governments’ attempts over the last two decades to widen participation in England’s universities? In this article I answer this question by examining a foundation year programme at a university in the nation’s former industrial heartland. Drawing on anthropological literature on rites of passage I analyse working-class participants’ experiences of this admission process. Its creators envisaged it as a rite that would seamlessly assimilate ‘diverse students’ into the university body, but I argue that it does not do so. Instead, as is to be expected from a rite, it marks participants. It thus prevents them from ever just being students in the eyes of themselves and their fellows.
Access, Privacy, and Gender divides in Teaching Online: Reflections from India
Authors: Patgiri Rituparna
Published: September 2021

The entry of the COVID-19 pandemic into our lives meant that the process of teaching and learning shifted online. While issues of digital divide have been in the limelight, some other problems related to online teaching have remained under the radar. For instance, are there are any privacy concerns associated with online teaching and learning? How does one discuss sensitive matters like gender, religion and caste in an online class? Also, most importantly, how does one ‘teach’ and/or ‘learn’ during a crisis? In this piece, I wish to explore some of these issues drawing from my teaching experiences in New Delhi – India’s capital city, in the past year.

This study aims to determine the effect of a university elective course focusing on gender on students' gender attitudes, critical thinking dispositions, and media literacy skills. The research design was quasi-experimental, and the study was conducted with a pretest/posttest control group. The sample of the study consisted of 74 students who took a course on gender during the fall semester of the 2016-2017 academic year and 70 students who had similar characteristics but did not receive the course. In the pretest and posttest evaluation conducted in the first week and the last week of the semester, respectively, the Student Information Form, the Gender Roles Attitude Scale (GRAS), the Critical Thinking Dispositions Scale (CTDS), and the Media Literacy Scale (MLS) were administered to the students in both groups. The Course Satisfaction Assessment Form was administered at the end of the term to the students who enrolled for the gender course. The GRAS scores of the experimental group increased at the end of the course (p<0.05). The GRAS total mean scores of both the groups were similar in the pretest, but there was a statistically significant difference between their total mean scores in the posttest (p<0.05). This study recommends more comprehensive and long-term studies on integrating a gender course into the university curriculum, which will help develop students' critical thinking disposition and media literacy skills and raise awareness of gender equality among students.

Authors: Ocampo Ponce Manuel
Published: September 2021

Aunque el auge del transhumanismo progresista extropianista que apunta a un posthumanismo se ha desarrollado en las últimas tres décadas, es fácil ver que se trata de un asunto del pasado, del presente y del futuro. Es un hecho que desde que el hombre empezó a intervenir en la naturaleza ha superado muchas fronteras impuestas por su precariedad. Ya Aristóteles se había referido al hombre como homo faber. No obstante, frente a los avances tecnológicos, últimamente ha surgido una respuesta a las propuestas de los transhumanistas por parte de los que se han llamado bioconservaduristas.  Ambos puntos de vista coinciden en que no todo lo que se puede llamar “mejoras” al ser humano, tiene el mismo estatuto ontológico y moral. También resulta interesante ver si es posible que el transhumanismo llegue a un extropianismo o a un posthumanismo, lo cual conduce el discurso científico a un plano filosófico. El propósito de este trabajo es descubrir los alcances y los límites ontológicos de este movimiento, a partir del concepto de naturaleza desarrollado por santo Tomás de Aquino, cuya propuesta es clásica y perenne. Veremos cómo el concepto de naturaleza en santo Tomás nos arroja luz para responder las interrogantes que últimamente se han planteado los intelectuales de este movimiento filosófico, científico y cultural.
Calidad cualitativa: ocho pilares para una investigación cualitativa de calidad
Authors: Tracy Sarah
Published: September 2021

Este artículo presenta un modelo de calidad en la investigación cualitativa que es excepcionalmente amplio, aunque flexible, ya que distingue entre los medios (métodos y prácticas) y los fines de la investigación cualitativa. El artículo ofrece en primer lugar una contextualización y una justificación de la conceptualización. Luego, la autora presenta y explora ocho aspectos clave de calidad en la investigación cualitativa. incluyendo (a) tema valioso, (b) rigor elevado, (c) sinceridad, (d) credibilidad, (e) resonancia, (f) contribución significativa, (g) ética y (h) coherencia significativa. Esta conceptualización de ocho puntos ofrece un modelo pedagógico útil y proporciona un lenguaje común de buenas prácticas cualitativas que pueden ser reconocidas como integrales por una variedad de audiencias. Mientras defiende estos marcadores de calidad, el artículo deja espacio para el diálogo, la imaginación, el crecimiento y la improvisación.
Las cuestiones de debate de la Ciencia Política como docencia práctica en un entorno de enseñanza semipresencial y virtual
Authors: Collado Campaña Francisco , Valencia Sáiz Ángel
Published: September 2021

Esta investigación en el ámbito docente presenta una propuesta de formación practica para las asignaturas de introducción a la Ciencia Política que tiene como objetivos desarrollar la tolerancia, la argumentación, el juicio crítico, la capacidad de acuerdo, la presentación en público y el interés por la política como competencias entre los alumnos en escenarios de docencia no presenciales. Esta propuesta práctica se centra en la formación de grupos de trabajo dedicados a documentarse, analizar y exponer un posicionamiento político ante una cuestión de debate que esté presente la vida pública y que esté relacionada con el temario de las clases teóricas. Para ello, determinamos las posibles dificultades que pueden encontrarse en escenarios de semipresencialidad y virtualidad, exponemos el diseño y la ejecución de esta propuesta en tres clases y mostramos los resultados tras una encuesta aplicada a los alumnos para conocer el exito de una primera implementación durante el curso 2020/2021. Finalmente, comprobamos como esta propuesta docente permite mejorar competencias básicas y necesarias para el desempeño profesional en el seno de democracias representativas y reforzar los conocimientos teóricos de los estudiantes.
Los derechos fundamentales más allá de los derechos fundamentales. Notas para enseñar Derecho Constitucional
Authors: Álvarez Rodríguez Ignacio
Published: September 2021

El presente artículo científico pretende demostrar que el contenido de los derechos fundamentales, entendidos estos en su vertiente internacional y más concretamente convencional en interpretación dada por el Tribunal Europeo de Derechos Humanos, impregna (o debería impregnar) la actuación e incluso esencia de diversos poderes públicos institucionales (“parte orgánica” de la Constitución), más allá de los análisis tradicionales que circunscriben su fuerza de obligar sólo en los derechos fundamentales (“parte dogmática” de la Constitución).

Published: September 2021

Este escrito se funda en un estudio que se propuso comprender las expresiones de un grupo de estudiantes frente al desafío de participar de una clase invertida como espacio para repensar las TIC hacia las futuras prácticas docentes. Y, cómo la agencia transformadora posibilita repensar el futuro rol docente al incorporar nuevas metodologías de enseñanza mediadas por la tecnología. Participaron del estudio estudiantes matriculados en la carrera del Profesorado en Ciencias Jurídicas, Políticas y Sociales, de una universidad argentina. La investigación se desarrolló bajo los lineamientos de las intervenciones programáticas que tienen como finalidad generar puentes entre la teoría y la práctica educativa. Para la recolección de datos se usó un cuestionario con preguntas abiertas que indagó las expresiones de los estudiantes sobre clase invertida y agencia transformadora. Los resultados muestran que los participantes logran generar rupturas con prácticas educativas encapsuladas en vista a incorporar enfoques pedagógicos que incluyan las TIC en los procesos de enseñanza y de aprendizaje. Se concluye que los análisis proporcionan una contribución para repensar la educación superior y la formación docente inicial de cara a los nuevos desafíos que los recursos digitales marcan en la sociedad de la información.

Authors: Marková Petra , Prajová Vanessa
Published: September 2021

At present, there are a large number of manufacturers operating on the market, which are engaged in the production and distribution of mechatronic and robotic toys. These toys range from the cheapest and simplest to sophisticated costly models for play education. Looking at the market offer, it can be stated that mechatronic toys are being produced, which are intended for children of several months. When developing children’s and educational robotics, it is, therefore, necessary to take into account the psychomotor development of the child. Respecting or not respecting it has a major impact on the success of the toy for the consumer and the fulfillment of the educational goal for which it is intended. Last but not least, in connection with the child’s development, the question arises as to what ergonomic principles, when designing toys intended for children depending on age, need to be respected and implemented into solutions to eliminate problems related to the development of children’s and educational robotics. The subject of interest in the article is the age groups of children from birth to preschool age. The aim of the article is to identify which factors in the construction of children’s robotic toys for the youngest children up to the period of preschool age are key from the point of view of ergonomics.

Published: September 2021

In this work were analyzed factors and working conditions that leads to the wearing of junk mills tools that are a part of junk removal equipment used in drilling and workover of borehole. Such equipment is a part of oil and gas industry and work under condition of intense abrasive wearing with increased pressures and cyclic loads. Was established that traditional hardfacing materials based on the Fe-Cr-C system are not effective for improvement of abrasion resistance of elements of such equipment due to their low crack resistance and low hardness of chromium carbides. The aim of this work was to increase a durability of that equipment by using of flux cored electrodes with reaction components of pure metal powders, which leads to forming the fine-grained structure with increased hardness. Powders of Ti, Mo, B4C and their combinations were used. Structures of the hardfacing coatings were investigated by method of metallography, scanning electron microscopy (SEM). Abrasion wear tests were held under condition of fixed and non-fixed abrasion. Using of pure metal powders led to formation of a fine-grained structure with grains of Mo2FeB2 that forms around TiC, which work as modifier. It was investigated that the researched material based on Fe-Ti-Mo-C-B system that was used for increasing the wear resistance of junk mills led to increasing of the TBO period in 1.5-1.6 times comparing with serial hardfacing materials based on tungsten.

Authors: Bołoz Łukasz
Published: September 2021

The growing requirements and needs of users as well as a strong emphasis on pro-ecological solutions cause an increasing interest in battery-powered electric mining machines. Internal combustion machines consume oxygen, generate noise, fumes and heat, which affects work in underground mines, and minimizing these factors is expensive. Battery solutions allow achieving the same operational parameters of machines with significantly higher safety, comfort and work culture. The problem, however, is their range or working time. The article presents global trends in the development of battery-operated machines for underground mining. Various machines in battery-powered versions have been presented. The applied solutions have been discussed, especially in the field of battery replacement or recharging and braking energy recovery. Manufacturers around the world offer more and more battery-powered machines. Some producers are announcing complete replacement of combustion solutions with electric ones within the next few years. There are also hydrogen machines on the horizon, which will probably be the next step on the road to a zero-emission industry.
Building a Circular Economy Model for Managing Exploitation of Household Used Devices on the Example of Washing Machine Driven by DC Motor Along with Components
Authors: Saleem Usman , Kaźmierczak Jan
Published: September 2021

In the article, the authors describe, using the example of a selected class of technical means, their concept of replacing the “classical” linear management (exploitation) model with a circular economy (CE) model. An example of an object for which the authors plan to test the feasibility of the concept presented above is a household washing machine driven by a DC motor. The description of this object included in the article considers its complexity and multiplicity of assemblies, sub-assemblies, and elements. The DC electric motor driving the washing machine was considered the most important from the point of view of the created model, especially in terms of the possibility of maintenance and repair. For such an engine, the article presents the maintenance and disposal model as elements of the concept of building a ‘circular’ business model. The authors assumed that the formal basis for such a model would be the so-called circular model. The methodology and plan of the research carried out at Super Asia washing machine company in Pakistan were introduced, and the research results were shown. With the use of these results, an attempt was made to assess the requirements that the application of the CE business model places on manufacturers of a selected class of devices, both in their manufacture, repair, sharing and dematerialization. The concept of further research is described at the end of the article.
