Speaking proficiency is one type of language ability to be achieved in modern language teaching, including Arabic. Speaking is the main means of fostering mutual understanding, reciprocal communication, using language as the medium. In other words, speaking ability does not only play a role in language learning but also plays an important role in other learning. Based on the results of interviews with Arabic teachers at MA Mu'allimat NWDI Pancor, researchers found that there was little willingness and motivation of students to learn Arabic, minimal provision of vocabulary to practice speaking Arabic and the absence of the Maharah Kalam module to facilitate Arabic practice. The learning media used is an Arabic lesson package book. So it is necessary to develop the Maharah Kalam module to make it easier to speak Arabic.

The aims of this study were: 1) To develop the speaking skill module for class X MA Mu'allimat NWDI Pancor, 2) To find out the response of material experts, media/design experts and students to the speaking skill module for class X MA Mu'allimat NWDI Pancor, 3) To find out the students' speaking ability in Arabic from the development of the speaking skill module for class X MA Mu'allimat NWDI Pancor. The research method used in this study refers to the R&D model with the ADDIE model which is one of the systematic (structured) learning design models, which means that it is programmed in sequence as an effort to solve student problems related to the required learning resources and student characteristics.

The research that produces the final product in the form of a Maharah Kalam module is a type of R&D (Research and Development) using the ADDIE development model. The ADDIE model development flow is in stages (1) analysis, (2) design, (3) development, (4) implementation, (5) evaluation. The results of the material expert validation for the material in the speaking skill learning module were 88% (feasible). And the validation results of design/media experts for the speaking skill module design are 92% (Very Feasible). The response of students after learning to use the speaking skill module was 92% of the response "yes" which means that learning to use the speaking skill module was declared successful. And student learning outcomes after using the speaking skill module at pre-test 64.33 < post-test 84.00. This means that using the maharah module in the learning process is effective.
The Purpose of Higher Legal Education
Authors:   National Research University Higher School of Economics, Ilyin Anton V.
Published: February 2023

The higher legal education is undergoing permanent reforms to adjust it to the needs of the day, to make it accessible to those who do not want to work as a lawyer in the future. Can this be done in such a way that legal education after such a reform would still allow legal work to be efficient? Maybe it is time to divide legal education into ordinary (for mere mortals) and branded (for the elite) in order to satisfy the demand for both “working legal bees” and for the “actual honey of jurisprudence”? In the article, I analyse the limits of reforming legal education and the grounds for dividing law faculties.

The Legal Nature of Refusal of Medical Aid in Comparison with Passive Euthanasia
Authors:   St. Petersburg State University, Liubin Ivan V.
Published: February 2023

The article is dedicated to the problem of establishing differences between patient’s refusal of medical aid and passive euthanasia. While the right to refuse any medical aid is fully established in the Russian laws, euthanasia on the other hand is prohibited in any and all forms, including passive euthanasia. That creates a problem of establishing which one is which in a specific situation. There are examples of people refusing treatment up to the point of death being in sound mind — can it be considered a case of passive euthanasia? The author arrives to the conclusion that while some may believe that passive euthanasia is the same thing as refusal of medical aid these two institutions shall be considered different. While euthanasia can be prohibited by the state, because it involves relations with the state about actualisation of the right to life, refusal of medical aid is different as it involves assessment of personal values that is beyond the control of any State, so prohibiting refusal of medical aid shall be considered impossible.
"UNION" OF AN ARTIST WITH A NON-HUMAN AGENT: UTOPIA OR A WORKING MODEL OF ARTISTIC PRODUCTION?
Authors:   Higher School of Economics “National Research University”, Fadeeva T.E.
Published: February 2023

The subject of the article: works of contemporary art created by non-human agents, on the example of which one can analyze the ways of interaction of contemporary artists with non-trivial media (algorithms, robots, "half-life artists", etc.). The object of the article: the impact of technological innovations on contemporary art production, as well as the need, in connection with the artist's appeal to science and the latest technologies, to rethink the goals and objectives of communication through images and the very concept of art. The purpose of the project: to update the information for the scientific world about the strategies of interaction between a human artist and a non-human agent, as well as about the nature of this interaction. Results of the work: the study showed that the creation of a work of art (both physical and as part of a post-production strategy, as a re-significance) – despite the criticism of anthropocentrism by representatives of the Actor-Network Theory and individual media theorists, should still be understood as purposeful activity inherent in a human, but not in a non-human agent. Appeal to non-human agents can be considered within the framework of the paradigm of "assistive technologies" and "chimerical" actor. Scope of the results: expanding the boundaries of the application of art history methodology and related disciplines, which contributes to the development of a language for describing the phenomena of contemporary art in the interdisciplinary field of modern media, in particular, in the dynamically developing field of art & science. Conclusion: Based on the results of this study, key trends were identified that determine the nature of our interaction with the other in the process of creating a work of art and interacting with it.

práctica comparada del secreto profesional de los periodistas
Authors: Barberá González Rafael
Published: February 2023

El secreto profesional del periodista en España encuentra su acogida en la Constitución de 1978. En esta materia, como en muchas otras, la situación española debe compararse con la que se da en países de nuestro entorno geográfico-político. Realizar un análisis de las realidades en esta materia nos ofrece un denominador común que es el de que España no es el único país en el que el desarrollo legislativo del secreto profesional es poco explícito. Para comprender esta situación es conveniente incidir en lo que establece la Constitución para valorar su contenido y los límites que ofrece.

Published: February 2023

El presente artículo analiza la representación cinematográfica del poder y su disputa a través de la ordenación vertical de los espacios visuales y narrativos de la pieza fílmica «High-Rise». Para ello, acudimos a un enfoque interdisciplinario, a caballo entre lo audiovisual, lo político y lo metajurídico, bebiendo de los aportes, sobre todo, de Michel Foucault y Byung-Chul Han. La investigación demuestra que en la película visionada el poder es representado mediante convenciones espaciales universalmente aceptadas, que resaltan las dislocaciones sociales y antropológicas que surcan los personajes a lo largo del relato.

Estética y ética del automóvil como motores de la no ciudad
Authors: Palacios Martínez Carlos Sergio , Ortiz Brizuela Miguel Adolfo
Published: February 2023

El presente texto es resultado de una investigación doctoral por concluir que hace un esfuerzo por vincular el fenómeno de la estética del automóvil, su morfología y percepción, con la ética urbana, o las formas de actuar en los espacios públicos. Analíticamente, el caso paradigmático que se usó es el mercado del automóvil urbano en México. Metodológicamente, se hace un recorrido histórico por el devenir estético del automóvil hasta su instauración como monopolio radical de la movilidad urbana. Posteriormente, se muestra un cambio en la estética imperante en el mercado, que va, de las estéticas del estatus, a las estéticas del poder; a esto se suma un estudio sociológico a trecientos entrevistados en la ciudad de Aguascalientes que muestra la percepción sobre la retórica física de los vehículos. El estudio arrojó el hallazgo de que la estética del automóvil ha venido creciendo en agresividad a medida que la seguridad ha sido convertida en un recurso escaso. Se argumenta que el fenómeno no solo es una muestra de enclasamiento, sino un proceso de desdemocratización del espacio urbano a un nivel profundo. Se discute, como conclusión, que las estéticas del automóvil tienen un papel fundamental en el devenir de la no ciudad.
Batallando entre redes sociales y la inteligencia emocional en los adolescentes
Authors: Veloza Gamba Raúl
Published: February 2023

La siguiente investigación documental de tipo descriptivo, en la cual se busca analizar la variable de las redes sociales y la inteligencia emocional, a través de una revisión bibliográfica de trabajos en los que se busca establecer la relación que existe entre las mismas y el efecto que tienen sobre los adolescentes como sujeto principal en el estudio, teniendo como conclusión de que las redes sociales afectan negativamente en la inteligencia emocional. Sin embargo, se genera una objeción puesto que los estudios, al revisarlos en conjunto, no logran determinar un proceso causal; es decir que, si bien los adolescentes que usan menos redes sociales presentan un mayor desarrollo de inteligencia emocional, no se puede decir que este mayor desarrollo se debe a la no utilización de las redes sociales, sino que se les puede identificar porque no las usan en la misma medida que las otras personas por lo que el no uso de redes sociales es más un indicador que la razón por la cual se desarrolla el fenómeno.

Conformación de un espacio en disputa: intervenciones urbanas y organización territorial en los orígenes de la Villa del Bajo Belgrano
Authors: Snitcofsky Valeria Laura
Published: February 2023

Ubicada en el norte de la ciudad de Buenos Aires, sobre tierras cercanas al Río de la Plata, la Villa del Bajo Belgrano se conformó hacia mediados del siglo XX como un espacio intensamente disputado, por el alto valor potencial del suelo sobre el que se emplazaba. Esta singularidad hizo que fuera objeto de tempranos intentos de desalojo que tuvieron como respuesta, a su vez, una organización pionera por parte de sus habitantes. Por lo tanto, indagar el período constitutivo de la Villa del Bajo Belgrano permite iluminar, a partir de un caso puntual, los primeros vínculos de negociación y confrontación establecidos entre agentes del Estado y referentes territoriales de un barrio informal, entre la Gran Depresión y mediados de la década de 1960.
La ‘cuestión’ del acceso a tierra de la Agricultura Familiar en el Cinturón Hortícola de La Plata (Buenos Aires, Argentina)
Authors: Mosca Valeria Ana
Published: February 2023

A través de la utilización de fuentes primarias –recolectadas mediante entrevistas y observaciones participantes- y secundarias –relevamiento de datos censales y estadísticos así como sistematización de bibliografía existente sobre la temática- y basados en una metodología cualitativa, en este artículo buscamos analizar cómo se expresa la cuestión del acceso a tierra de la agricultura familiar en un territorio específico: el Cinturón Hortícola Platense. Para ello hemos buscado responder, por un lado, cuáles son los actores/actividades con las que la agricultura familiar entra en competencia por la tierra, y por otro, cuáles son las modalidades en que accede a la tierra este actor en la actualidad. Luego de haber definido ello veremos las problemáticas de acceso a tierra como condicionantes estructurales en la calidad de vida y modalidad de producción de los agricultores familiares.
Tipos de hábitat: una herramienta teórica para conocer la estructura urbana de un municipio periférico del Aglomerado Gran Buenos Aires
Authors: Chiara Camila
Published: February 2023

Enmarcado en los estudios de demografía urbana, el artículo tiene como objetivo conocer los distintos tipos de hábitat que componen el municipio de San Fernando al año 2010, e indagar en las especificidades sociodemográficas de cada uno de ellos. Esta propuesta analítica –que proviene de la geodemografía mexicana y fue replicada en Argentina para la Ciudad Autónoma de Buenos Aires–considera que el período de urbanización y la forma de producción del espacio habitacional de las diferentes áreas de la ciudad definen tipos de hábitat diversos y les imprimen una serie de rasgos, características y dinámicas diferenciales y diferenciadas. Para abordar el objetivo propuesto, se apela a una estrategia metodológica cuantitativa en base a fuentes de datos secundarios. Como resultado, se busca determinar e identificar qué tipos de hábitat conforman el municipio para luego indagar en las particularidades sociodemográficas de cada uno de ellos.

Published: February 2023

El expansivo avance contemporáneo del turismo ha dado lugar a presiones cada vez más evidentes sobre los residentes, que son claves para lograr la sostenibilidad en todos los destinos turísticos. El objetivo principal de este artículo es comparar las percepciones de dos comunidades anfitrionas en lugares geográficos separados y tipos de destinos distintos. Se han escogido los significativos casos de San Martín de los Andes, en el norte de la Patagonia argentina, destino de turismo natural, y de Toledo en España, ciudad histórica y destino turístico cultural. La metodología empleada ha sido un análisis a través de un cuestionario. Los resultados demuestran que las dos comunidades tienen una percepción positiva del desarrollo de la actividad turística con una gran coincidencia en sus opiniones, aunque se detectan problemas particulares. El artículo resulta de interés para los gestores y planificadores públicos del turismo.
Una descentralización controlada: el Régimen de Coparticipación Vial Municipal de la provincia de Buenos Aires (1957)
Authors: Salomón Alejandra
Published: February 2023

Este trabajo aborda el Régimen de Coparticipación Vial Municipal de la provincia de Buenos Aires y sus potenciales efectos, en un contexto en el que los caminos de la red terciaria se convirtieron en un asunto socialmente problematizado. Con el objetivo de contribuir al estudio histórico de la gestión de los caminos rurales, y en base al análisis de contenido de fuentes primordialmenteoficiales (legislación, memorias gubernamentales, informes, publicaciones periódicas), se indagarán tanto el diseño y los criterios subyacentes en la nueva normativa como sus resultados iniciales en materia de recursos, profesionalización y equipamiento de las comunas. La hipótesis consiste en que la descentralización fiscal vial habría sido una política de fortalecimiento a las instituciones locales –aunque supeditándolas al control del gobierno provincial– a fin de impulsar el desarrollo del interior rural provincial.
Servicio ecosistémico del monte nativo frente a la contaminación atmosférica por material particulado sedimentable en Villa María, Córdoba, Argentina
Authors: Morán Ignacio Excequiel , Guzmán Leticia Ana
Published: February 2023

En el presente trabajo se plantea como objetivo determinar la variación de recolección de material particulado en los márgenes del monte, a los fines de comprobar el servicio ecosistémico de barrera física y filtrado de material particulado en suspensión. Se analiza la deposición de material particulado a barlovento y a sotavento en los márgenes de un monte nativo ubicado en el espacio periurbano de la ciudad de Villa María, Córdoba, Argentina. Se estableció una propuesta metodológica no invasiva para el medio natural adaptada de la norma IRAM N° 29.299. Los resultados dan una diferencia significativa del material particulado recolectado entre ambos márgenes del monte nativo; asimismo el método muestra ser eficiente, económico y replicable. El monte nativo cumple con el servicio ecosistémico marcando así la importancia de la conservación de esta ecorregión en vías de extinción en el país.
Redescubriendo la gobernanza urbana: un abordaje desde perspectivas territoriales en disputa
Authors: González Giselle
Published: February 2023

Durante los últimos treinta años predominaron distintos estudios sobre la gobernanza desde un punto de vista de gobernabilidad. Desde diferentes modelos o paradigmas la gobernanza se configura como un sistema de hegemonía al suponer que la colaboración y el consenso –entre ciudadanos igualmente habilitados para el ejercicio del poder- determinan la toma de decisiones políticas. No obstante, la consolidación de otros modelos de gestión urbana, empresarial y local, críticos de esta perspectiva inicial, abre la discusión sobre sus principios y métodos, destacando el carácter relacional y desigual de las relaciones de poder. Al incorporar contradicciones en el modelo hegemónico es posible identificar conflictos y direcciones heterogéneas que adopta el cambio en los esquemas de gobernabilidad. Estos debates problematizan los marcos normativos de la gobernanza e introducen la noción territorialespacial como eje de las intervenciones. Se concluye que la gobernanza se constituye como una corriente dominante en las transformaciones socio-políticas y económicas a nivel global pero no alcanza a simbolizar el arreglo espacial y la especificidad de relaciones sociales de cada territorio.

El presente estudio analiza las causas y motivos por los que se han desarrollado en La Roda (Albacete) diversas líneas de una industria tan peculiar como la fabricación de pinturas (temple, barnices, masillas…). Para ello, identificaremos dentro de la variedad de sistemas fabriles empresariales cuál se asemeja más al rodense y demostraremos la existencia de un Distrito Industrial (DI) de corte marshalliano en la localidad, convirtiéndose éste en el objetivo esencial de la investigación. Una hipótesis que se traduce en el principal objeto del estudio y que se ve confirmada en él.

the growing doctrinal crisis of the modern liberal economic system is under analysis. Under the weight of its own contradictions, it has aggravated a number of global threat and world-scale conflicts. It is shown that the result of such a process is the total lack of personal freedom: as a person, as an employee, as a consumer, etc. The author raises the question about the need of searching for a new vector of civilizational advancement based on a model, fundamentally different from the currently dominant, but rapidly exhausting its potential, western (predominantly pro-American) development model. A new way of managing will require the transformation of many social institutions and relations, and a new quality of a person as well. The priority strategic direction should be the desire to satisfy public interests based on the highest criteria of human reason and culture, rather than private business interests focused on extracting money. The author elaborates that the methodological core of the concept of noonomy developed by Prof. S.D. Bodrunov makes it possible to design a qualitatively new model of social interaction via means of the new industrial society of the second generation (NIS.2).

This study examines the findings of numerical analysis studies that were conducted to determine how the arrangement of the blade distributors in a fluidization system affects the distribution of air flow distribution. In contrast to the conventional methods, which give the particle a swirling motion, the current fluidization systems produce a circular movement of a beds. Therefore, the influence of twist angle blade (60° and 100°) was investigated through to the horizontal inclination angle (15°) and radial inclination angle (10° and 12°) blade distributors. In a fluidization systems, the simulation was used to calculate and assess the performance outcomes of three velocity components: tangential velocity, axial velocity, and radial velocity. These components represent the flow of fluid inside the plenum fluidizations systems. According to the results of the numerical study that used a horizontal inclination of 15°, the velocity of the airflow in the fluidization systems may reach up to 8 m/s. This circumstance occurred because the air flow was quite near to the large opening area where the airflow was allowed to enter. This is due to the less of an interruption to the airflow when it enters the gap area between the two blades distributor.

The protection of digital media become crucial and needs to be developed as technology continues to become more advanced. This is to cater to the problems in copyright protection and data security. This paper presents a new non-blind image watermarking algorithm applying modified non-separable Haar wavelet transform (NSHWT), singular value decomposition (SVD), Arnold’s cat map and Rabin-p cryptosystem. The traditional transform domain watermarking (DWT) is resource-consuming, especially when performed on large image data. In order to improve on this issue, the proposed algorithm applied the modified NSHWT, a much more efficient alternative to the DWT. Another concern of digital watermarking algorithms is it is often publicly known, so encryptions are important to keep the image secure. The embedded watermark image is protected by scrambling the image using Arnold’s cat map, and the scrambling parameters are encrypted with the Rabin-p cryptosystem to keep the algorithm secure. In general, the application of modified NSHWT and SVD makes the watermark highly robust against image processing and geometric processing attacks, and its security is ensured with the protection by Arnold’s cat map and Rabin-p cryptosystem. There are already many algorithms with high imperceptibility and robustness, but in finding the perfect balance, authors often forsake other metrics such as efficiency, security, and flexibility. These are also essential when the algorithm is considered in real applications. Thus, the proposed algorithm is evaluated in terms of imperceptibility, robustness, and efficiency. The algorithm achieved imperceptibility results of 51.5157 average PSNR and 0.9991 average SSIM, and robustness results from 0.9710 to 0.9966 NC values. The algorithm is also around 40% faster to execute with modified NSHWT compared to the traditional DWT. Finally, it has a high embedding capacity of 6 bits per pixel. Overall, results show that the algorithm is highly imperceptible and robust against image processing and geometric attacks, while additionally being secure and flexible.

The current trend of urbanization forces building development in urban areas, but the limitation of land in the area forces the development to be conducted upwards instead of sideways; thus, high-rise buildings will continue for decades. The façade of a high-rise building plays the most significant role in connecting the indoors and outdoors, therefore, having the most direct effect on the surrounding environment. Nowadays, glass is one of the most popular materials used in a high-rise building’s façade. The abundance of high-rise buildings with glass façades is also found in the Jakarta Metropolitan Area. However, the climate condition of the Jakarta Metropolitan Area proposes challenges in designing high-rise buildings with glass façades to accommodate outdoor human comfort. This study aims to review whether people achieve human comfort in an outdoor area of high-rise buildings with glass façades in the Jakarta Metropolitan Area. Using literature review through content analysis, this study found that theoretically, high-rise building with glass façade does not naturally respond to the climate condition of the Jakarta Metropolitan Area in providing human comfort. However, human psychological factors need to be considered in determining whether a condition is perceived as comfortable, as occupants of an outdoor environment have different expectations than those indoors. Thus, further assessments need to be conducted to determine whether developing high-rise buildings with a glass façade is appropriate to support outdoor human comfort in the Jakarta Metropolitan Area.
