Los discursos científicos en disputa al interior del campo jurídico
Authors: González Manuela Graciela , Lanfranco Vazquez Marina Laura
Published: July 2021

Dentro de nuestro proyecto, el que transita el campo jurídico, lxs investigadorxs nos encontramos con la necesidad de escribir en revistas jurídicas para cumplir una de las etapas de este proceso. Desde allí, nos interrogamos acerca de si escribimos por ¿necesidad, obligación o en busca de legitimar nuestros hallazgos? En ese derrotero ¿cómo se compatibilizan nuestros deseos?Al introducirnos en estos interrogantes, surgen preguntas más específicas sobre nuestro hacer cotidiano ¿qué rol cumplen las revistas científicas jurídicas en la construcción, difusión y retroalimentación del conocimiento jurídico?, ¿escribimos de una forma estandarizada, normada, preestablecida y, desde la práctica aprehendida de “saber escribir”, “saber dónde enviar” nuestros aportes?Por otra parte, nos interesa recuperar del imaginario académico ¿qué grado de veracidad tiene la siguiente afirmación?: la legitimación recibida a través de la publicación nos garantizará que algunxs decisorxs jurídicxs y políticxs tendrán acceso a este material para fundamentar sus trabajos, sentencias y proyectos legislativos. Y, ¿qué literatura eligen lxs juecxs para fundamentar sus sentencias?Partiendo, de estos interrogantes y de otros que irán surgiendo de nuestra línea argumentativa fortalecida por el material bibliográfico que utilizaremos, pretendemos reflexionar críticamente desde nuestra doble función de integrantes de una revista y de personas que debemos/queremos escribir en revistas científicas tratando de hacerlo desde una distancia óptima que nos permita capturar lo novedoso de este trabajo para fortalecer nuestro campo.
La evaluación de la ciencia en España. La necesaria compatibilización de los estándares formales y materiales de evaluación científica
Authors: Álvarez Álvarez Leonardo , Fernández Sarasola Ignacio
Published: July 2021

Este trabajo pretende someter a enjuiciamiento los criterios empleados por los organismos de evaluación de la investigación científica en España en el ámbito de las ciencias sociales. Estos criterios han transcurrido hacia una formalización que descuida el contenido material de lo publicado. Sobre ello ha advertido una reciente sentencia del Tribunal Supremo, de 12 de junio de 2018. El trabajo pretende formular una propuesta para compatibilizar, en el ámbito de las revistas jurídicas, la necesaria existencia de criterios formales de evaluación con los materiales requeridos por las exigencias de la ciencia.

Authors: Becerril Gil Anahiby Anyel
Published: July 2021

La Inteligencia Artificial (IA) y las capacidades de aprendizaje automático están creciendo a un ritmo sin precedentes. La IA se presenta como una herramienta que puede mejorar el nivel de vida de los individuos, incluso resolver algunos de los desafíos más grandes del mundo. También es vista desde el enfoque de la salvaguarda de los ciudadanos, la defensa de las naciones y el mantenimiento de la paz y la estabilidad internacional. La IA se considera una tecnología de doble uso. La mejora en la toma de decisiones que se busca lograr con el empleo de IA se considera también en el ámbito de la ciberseguridad. A medida que la IA está cada vez más integrada en los sistemas críticos, deben protegerse ante posibles ciberataques. Los targeting killings, la desinformación y el empleo de sistemas inteligentes para buscar vulnerabilidades en infraestructuras se presentan como uno de los grandes desafíos de estos tiempos. En este trabajo analizamos diversas interrogantes sobre la regulación jurídica de la IA y sus impactos en el ámbito de la ciberseguridad.

The pairing of God's name "the wise" with his name "all-knowing" in the Qur’an
Authors: ad-Daghamin Ziad
Published: July 2021

The study surveyed all the sixty-three instances where Allah's name the Wise got paired with His name the All Knowing. It defines the meaning of each name, and investigates the contexts of their pairing together, explicating contexts where the Wise precedes the All Knowing and vice-versa. It was found that Allah's name the Wise precedes the All Knowing in contexts where the following topics are discussed: building up faith by proving the oneness of Allah and rebutting all falsehood about it, highlighting the truth, and proving resurrection. On the other hand, Allah's name the All Knowing precedes the Wise in contexts where the following topics are discussed: appreciating prophet-hood, giving legislations, recommending patience, clarifying Allah's law and practice with the disbelievers, and exposing hypocrites.

This study aimed at developing a scale for measuring factors of students’ reluctance to participate in school radio programs. The sample consisted of )121( students representing grades 10 and 11 in one of the schools in South Al-Batinah governorate in the Sultanate of Oman. Results revealed appropriate indicators of validity and reliability for the scale. The factor analysis yielded a 15-item scale consisting of five factors: poor psychological readiness, poor encouragement, fear of criticism, absence of training, and poor self-willingness. Internal consistency reliability coefficients of the five factors ranged between 0.60 and 0.79. Results also showed that low achievers were more reluctant to participate in the school radio programs than high achievers. The study ended with a number of recommendations such as using the scale by supervisors of school radio programs to overcome factors of students’ reluctance to participate in the school radio programs and conducting other studies to verify the applicability of the scale for other samples.

The reality of worship and the opinions of scholars in judging the ranks of worship
Authors: Kharma Marwa
Published: July 2021

The rank of worship is the most honorable and highest of the ranks of love, and it expresses the rank of (Iihsan) - the highest level of religion - and for the honor and importance of this rank, I devoted a research to it entitled (The reality of worship and the opinions of scholars on judging the ranks of worship), And I divided it into an introduction, three topics and a conclusion. As for the first topic, it was: Explaining the truth of worship, its benefits and honor, and the second topic in a statement: The relationship of worship with monotheism, Then the third topic was in a statement: Types of worshipers and worship, their ranks and judgments, and I concluded with a conclusion with the most prominent results. That: worship is the perfection of love with perfection of submission, and it is the pure right of God Almighty over His servants to unify worship and unify love, and that people differ in their ranks of worship. The opinions of scholars differed in ruling on the validity of these ranks, and that the basis for ruling on the validity and acceptance of worship is the intention of the worshiper. And that the place of worship is achieved by not sharing God Almighty, whether in the deeds of the outward or inward deeds, so (There is no god but God) requires that: There is no worshiped or beloved but God alone, with no partner.

إن مرتبة التعبد هي أشرف مراتب المحبة وأعلاها، وهي تعبّرعن مرتبة الإحسان _أعلى مراتب الدين_ ولشرف هذه المرتبة وأهميتها فقد خصصت لها بحثا بعنوان (حقيقة التعبد وآراء العلماء في الحكم على مراتب العبادة)، وقسمته إلى مقدمة وثلاثة مباحث وخاتمة، أما المبحث الأول فكان في: بيان حقيقة التعبد وفوائده وشرفه، والمبحث الثاني في بيان: علاقة التعبد بالتوحيد، ثم كان المبحث الثالث في بيان: أنواع العباد والعبادة ومراتبها والحكم عليها، وختمته بخاتمة فيها أبرز النتائج. وقد توصلت إلى: أن التعبد هو كمال الحب مع كمال الخضوع، وهو خالص حق الله تعالى على عباده بتوحيد العبادة وتوحيد المحبة، وأن الناس متفاوتون في مراتب عبادتهم، وقد تفاوتت آراء العلماء في الحكم على مدى صحة تلك المراتب، وأن أساس الحكم على مدى صحة العبادة وقبولها هو نية العابد، وأن مقام التعبد يتحقق بعدم الإشراك بالله تعالى سواء في أعمال الظاهر أو في أعمال الباطن، فـ (لا إله إلا الله) تقتضي أن: لا معبود ولا محبوب إلا الله وحده لا شريك له.

Damage Liability Insurance as an Alternative Means of Food Quality and Safety Management
Authors: Gurvich VB , Mazhaeva TV , Sinitsyna SV , Kozubskaya VI , Bortsova EL , Sheluntsova NG
Published: July 2021

Introduction: Widespread violations of mandatory requirements entails administrative measures that cause economic damage to both consumers and economic entities. In the context of the development of integration processes and harmonization of legislation, new, more effective approaches to the governmental control (supervision) and food quality and safety management based on prevention of violations and reduction of damage risks are being introduced. The objective of our work was to substantiate the necessity of damage liability insurance for producers and retailers as an instrument of improving quality and safety of foodstuffs and reducing risks of damages to consumers and economic operators. Materials and methods: We analyzed data of the Sverdlovsk Regional Rospotrebnadzor Office, the Center for Hygiene and Epidemiology in the Sverdlovsk Region, the Federal Service of State Statistics, the Regional Solid Household Waste Management Operator, the Yekaterinburg Municipal Unitary Enterprise “Spetsavtobaza”, as well as provisions of the Code of the Russian Federation on Administrative Offenses, using comparative and time-series methods. Results: We established factors accounting for the cumulative economic damage to consumers and economic operators from circulation of substandard food products and found that they contributed differently in terms of the amount of property damage and health damages to consumers. Administrative penalties are the main reason for the property damage to economic operators. Intestinal infections cause most physical and material losses to consumers and these damages are inevitably shared with the state. Dairy and meat industries with extremely high risks incur the greatest financial losses. The use of various approaches to food safety management, including damage liability insurance, will help minimize risks, prevent their consequences, and protect consumers and economic operators. Conclusion: Violation of regulations poses significant risks of damage to consumers and economic losses to economic operators. Insurance may be considered as an alternative means of risk management motivating businesses to ensure food quality and safety, protect consumers and help maintain their health, and reduce economic losses.
Hygienic Assessment of the Influence of Factors of Digital Environment on Adolescents
in the Process of Educational and Leisure Activities
Authors: Shubochkina EI , Ivanov VYu , Cheprasov VV , Ayzyatova MV
Published: July 2021

Background: The wide use of digital tools in teaching requires a hygienic assessment of their impact on the health and lifestyle of students. The objective of the study was to assess the impact of the digital environment on the health and lifestyle of adolescents, depending on the duration of use of electronic learning tools in educational and leisure activities. Methods: An anonymous online questionnaire-based survey of 111 high school and college students was conducted to establish their screen time in the educational process, when performing homework and at leisure, as well as indicators of wellbeing and lifestyle and health complaints. In addition, learning conditions in college computer classes, such as illumination, microclimate, air ionization, levels of electromagnetic fields, airborne concentrations of phenol and formaldehyde were assessed. Modern statistical methods (Student’s t-test, chi-squared test) and methods of evidence-based medicine were applied. Results and discussion: Almost 66 % of the respondents reported using electronic teaching aids (a computer or laptop) at school three or more times a week and severer symptoms of fatigue after such classes. Complaints typical of adult professional users were not common in adolescents, except for visual impairment over the past year (48.6 %). In computer classes, microclimate parameters were far from being optimal: illumination was lower than the regulated values; the levels of electromagnetic fields, ionization, and indoor air concentrations of phenol and formaldehyde were comparable to the appropriate standard values. We observed a high involvement of adolescents in the use of digital tools at home for educational purposes and especially at leisure. The intensive use of Internet (more than 4 hours a day) was associated with frequent complaints of headaches, visual impairment, sleep disorders, and poor self-assessment of the physical shape that may be attributed to the established decreasing number of teenagers engaged in physical culture and sports. Conclusion: The length of time spent in the Internet space for homework and leisure activities affects students’ health and lifestyle. This indicates the need to develop and implement preventive and educational programs for adolescents in order to minimize health risks posed by digital environment and confirmed by outcomes of distance learning.

of Cellular Communication
Authors: Gorokhov EB , Lyapkalo AA
Published: July 2021

Introduction: One of the main professional groups of workers in cellular radiotelephone communication includes technical specialists who serve and ensure trouble-free operation of radio transmitters of cellular base stations (BS). Transmitting antennas and BS equipment are powerful sources of radiofrequency electromagnetic fields (RF EMFs) and one of the main adverse physical factors of the working environment for technicians. RF EMFs affect the functional state of various systems of the human body including the nervous, cardiovascular, and immune systems. The objective of our study was to assess the exposure to RF EMFs of cellular communication technical specialists and to establish occupations with the highest exposure levels. Materials and methods: Instrumental testing of energy flux density of the electromagnetic wave generated by BS receiving and transmitting equipment was carried out at service sites of cellular communication facilities by technical specialists of the industry. The time spent by technicians at workplaces with high EMF levels during the average work shift was measured. Results: The analysis of collected data showed that 28 % of energy flux density values measured at workplaces exceeded the maximum permissible level for the personnel serving radio transmitters and spending from 12 to 61 % of the work shift in the specified conditions. We established that network construction engineers, network operation engineers, power engineers, technical audit specialists, network development engineers, and mechanics were exposed to increased RF EMF levels. Conclusion: Our findings indicate the necessity to monitor and reduce occupational exposures of technical specialists of cellular communication in order to improve their working conditions and prevent, inter alia, RF EMS-related diseases.

Published: July 2021

The article reports on the results of surgical treatment in 20 patients with bone tumors using a coating containing bioactive glass on the contact surface of the fixation plate. As a result of metallic osteosynthesis of the bones, infectious complications were observed in 1 (5%) patient and tumor recurrence was observed in 2 (10%) patients. Limb function after metallic osteosynthesis ranged from 72.3% to 97.4% depending on the location of the lesion focus. The quality of life of the operated patients increased to 75–85 points. Thus, the use of plates with bioactive glassbased material deposited on the contact surface of the plate, in metallic osteosynthesis for pathological bone fracture or at the risk of pathological bone fracture achieves more effective integration of metal plate with bone. Consequently, a better functional stability of the bone is achieved at the fracture site. Morphological examination of bone biopsy samples from the implantation site of the plate and the plate itself with the deposited bioactive glass-based coating revealed active regeneration of bone tissue. This resulted in an increase in the density of the restored bone. According to the results of histological and morphometric examination it can be stated that deposition of a material containing bioactive glass on the contact surface of the metal plate promotes reparative osteogenesis at the site of bone damage and its morphogenesis of the lamellar type.

The Concept and Implementation of Economic Policy According to Islamic Law
Authors: Asmawati Asmawati
Published: July 2021

The economy has improved very rapidly in the digital age. The birth of various policies that actually do not consider the religious side, which only cares about profit. This becomes a challenge in providing a factual answer to the conception of economic policy that is in line with economic principles in accordance with Islamic law.So, it is very urgent to re-explore the conception and implementation of economic policies outlined in Islamic law. The study is a conceptual study by conducting a literature review. This study focuses on theories related to the concept of economic policy in the perspective of Islamic law.The findings in this study indicate that economic policies in Islamic law have been stipulated in the Islamic texts which substantially prohibit policies that use people's property, criminalizing policies. Economic policies that are in accordance with Islamic law are policies that are fostering in increasing economic development.This economic policy has long been practiced by the Prophet (pbuh) and his companions during the period ofkhulafaurasyidin as a way to improve the economy with policies that are relevant to the objectives of the Islamic texts. The implication of this finding is that in carrying out economic policies always consider economic policies that are in line with the provisions of the Quran and hadith.

O texto divide-se em três seções que agrupam uma revisão de estudos afins: (a) Fundamentos teóricos sobre atenção e música; (b) Evidências neurocientíficas sobre atenção e música; (c) Aplicações terapêuticas da música na atenção.  Os estudos da musicologia cognitiva demonstram que agrupamentos perceptivos e expectativas são fatores determinantes para o recrutamento das diversas dimensões da atenção. Exames de neuroimagem, testes neuropsicológicos e estudos sobre a sincronicidade rítmica acrescentam evidências neurocientíficas sobre a forte relação entre música e atenção. As evidências relatadas neste estudo demonstram que música pode ser utilizada em contexto terapêutico com efeitos benéficos para pessoas com prejuízos na atenção ou como um recurso para desviar a atenção de sensações dolorosas ou situações estressantes.
Arthur Kampela e os Exoskeleton

Published: July 2021

Este artigo analisa os Percussion Studies IV e V de Arthur Kampela, onde a técnica e postura do violonista são transpostos para a viola. Ambas as peças questionam a técnica do violão, mesclando dedilhados característicos com o uso de um arco metálico. As obras são entendidas dentro de uma perspectiva gestual, onde o som e o gesto, o instrumentista e o instrumento coexistem dentro de uma relação física. Estudam-se a Tapping Technique, a emancipação entre mãos, a Air Guitar, e a ideia da música sem som. Sao revistas propostas científicas a favor de um entendimento corporal da prática musical: a técnica do violão segundo Hubert Käppel, a música visível de Dieter Schnebel, além de estudos sobre o gesto (Gritten e King, Godoy e Leman, Delalande, Cox, Oberhaus e Stange…). O estudo culmina com a tentativa de compreensão da maneira como o instrumentista se torna o cerne da composição.
Exploring pedagogical strategies for piano sight-reading
Authors: Sampaio Marcelo Almeida , Santiago Patrícia Furst
Published: July 2021

In a piano sight-reading (SR) experiment, 27 undergraduate students had their SR measured. It tested the hypothesis that transposition (control group) would be a pedagogical intervention better than rhythmic training and the use of four-handed repertoire (two experimental groups). The individual errors were collected from three tests in three difficulty levels (27 students x 3 tests x 3 levels), generating a total of 243 observations. Although students improved their performance by 30%, none of the pedagogical interventions had any significant effect (p=0.96). The results were: a) practicing reading in the bass clef, the rhythmic aspects more than the melodic ones, and the left hand more than the right one, brings more benefits to the piano SR performance; b) isolated SR strategies has little effect on students development; c) using a hybrid curriculum matrix with three or more significant predictors seems to be the most appropriate way to develop a SR competency.
Can Ubimus Technologies affect our Musicality?
Authors: Costalonga Leandro , Pimenta Marcelo , Wanderley Marcelo
Published: July 2021

Recent works recognize musicality is based on and constrained by our cognitive and biological system. Taking in account a concept from cognitive science - cognitive offloading - as a principle for technology-supported musical activities, in this paper we discuss some principles (guidelines) to be taken into account when designing, developing and evaluating computer music technologies, especially those related to ubimus. We think that Ubimus technology can shape the way we think about music and have a positive (or negative) influence on our musicality.

Los estilos de ejecución históricos en el tango como construcción socio‐cultural dan origen a la elaboración del canon del estilo musical que hoy conocemos. En dicha tradición estilística Aníbal Troilo es una de las figuras relevantes. En este trabajo analizamos modos de enunciación temporal de Troilo con el fin de encontrar indicadores de la construcción de los patrones témporo‐expresivos de su estilo. Para ello comparamos distintas interpretaciones del tango Mi Refugio aplicando herramientas computacionales sobre anotaciones manuales del beat. Calculamos curvas de tempo y las comparamos a través de un análisis de correlación y mediante regresión polinómica. Las comparaciones entre diferentes versiones fueron interpretadas mediante el análisis hermenéutico‐musical. Los resultados indican un uso consistente de patrones de regulación temporal en el fraseo de Troilo a diferentes niveles expresivo‐estructurales, más allá de las variaciones en la superficie musical de los arreglos. Además, se identificó un recurso de aceleración‐desaceleración con fines articulatorios en la comunicación de la forma.

Public participation in art performances has been leveraged by the use of technology as a mediating element between the public and artists. However, technological mediation alone may not be enough to ensure effective auditory participation. In this article, we present the performance “ O Chaos das 5 ”, an audiovisual digital performance with a strong technological support that had the support of game theory to achieve a more effective participation of the audience in their presentations.

Este artigo relata os resultados musicais e cognitivos alcançados com uma aluna autista de 11 anos, como parte de uma pesquisa de Doutorado realizada no departamento de Neurologia/Neurociências da UNIFESP de 2013 à 2017. No total foram 40h de aulas, no decorrer de 4 meses (duas vezes semanais com 1he20 min de duração cada). As atividades empregadas se basearam em propostas pedagógico-musicais lúdicas com enfoque nas propriedades do som e no emprego do movimento. Os principais embasamentos teóricos foram Pacheco (2009), Mateiro e Ilari (2011), Fonseca (2010) e Lent (2010). Os resultados apontaram para aquisição de conteúdos musicais baseados nas propriedades do som, bem como, melhora significativa em algumas habilidades cognitivas e na percepção do esquema/imagem corporal da aluna. Esse relato pode contribuir para formação de educadores musicais que tenham em seus contextos pedagógicos alunos com autismo (ou outros diagnósticos) ou para profissionais da área de saúde.
Gesto Musical e Transcendência em Nigun de Bloch
Authors: Verbisck Edison Valério , Lopes Eduardo
Published: July 2021

Ernest Bloch compôs em 1923 a obra “Baal Shem: Three Pictures of Chassidic Life”, constituída por três movimentos representativos do imaginário hassídico, respetivamente “Vidui”, “Nigun” e “Simchas Torah”. O segundo movimento tornou-se uma peça amplamente conhecida e incorporada ao repertório de violinistas. Bloch associa o nigun, interpretado pela voz humana, ao violino, colocando-o no lugar do Cantor ou Rabino. O violino incorpora o personagem orante que caracteriza o nigun, inclusive no gestual, utilizando a música como um veículo da materialidade para a transcendência (devekut). Através da análise expressiva, o presente ensaio pretende evidenciar as similaridades entre a composição “Nigun” e o género musical homónimo, ressaltando o gesto musical e a liberdade interpretativa, e despertar algumas reflexões sobre o tema, sem a pretensão de apresentar respostas definitivas ou conclusivas.

Abstract: Neoadjuvant chemotherapy is one of the therapeutic modalities used in the management of locally advanced breast cancer. Therapeutic response can be objectively assessed with RECIST and Ca 15-3 could be used to monitor response to breast cancer (BC) treatment. This study was aimed to prove the relationship between Ca 15-3 and response to neoadjuvant chemotherapy in locally advanced BC. The study was carried out at the Departement of Surgery Prof. Dr. R. D. Kandou Hospital Manado using a single-arm pre-post trial. Each patient would be performed Ca 15-3 test and clinical assessment (RECIST) pre and post chemotherapy for two sessions. There were 11 BC patients with invasive ductal carcinoma.  The average age was 60 years old and the majority had anemia and lymphocytopenia. There was a decrease in Ca 15-3 in each patient by a baseline of 21.8 U/mL pre-treatment and a decrease in the lesion size by 30.3 mm using RECIST. The results showed that changes in RECIST and Ca 15-3 level were correlated with each unit change in RECIST was associated with a decrease in Ca 15-3 level by 0.03 units (p=0.019). In conclusion, there was a decrease in Ca 15-3 level in response to chemotherapy, followed by a decrease in RECIST. There was a relationship between Ca 15-3 level and chemotherapy response assessed with RECIST after the second chemotherapy.Keywords: Ca 15-3, chemotherapy response, neoadjuvant chemotherapy, RECIST, breast cancer  Abstrak: Kemoterapi neoadjuvan masih merupakan pilihan utama terapi untuk kanker payudara (KPD) stadium lanjut local.

This research investigates the problem of cumulative degradation and random shocks a system like a centrifugal pump may experience during normal and adverse operating conditions. An accelerated life testing method was employed to determine the degradation of the pump under cumulative damage degradation and random shocks conditions. An age- Based policy was used to determine the optimum time interval that will minimize the total expected cost of the system. The random shock increases the number of failures and hence reduces the reliability of the system. The total expected preventive maintenance cost obtained varies from N1700.00 (One thousand seven hundred naira) to N16,000.00 (sixteen thousand naira), depending on the shock and shock duration. The methodology presented is useful and thus recommended for use to study cumulative damage degradation and random shocks for similar systems.

Bidirectional in recent years, Deep learning performance in natural scene image processing has improved its use in remote sensing image analysis. In this paper, we used the semantic segmentation of remote sensing images for deep neural networks (DNN). To make it ideal for multi-target semantic segmentation of remote sensing image systems, we boost the Seg Net encoder-decoder CNN structures with index pooling & U-net. The findings reveal that the segmentation of various objects has its benefits and drawbacks for both models. Furthermore, we provide an integrated algorithm that incorporates two models. The test results indicate that the integrated algorithm proposed will take advantage of all multi-target segmentation models and obtain improved segmentation relative to two models.
