ON STRENGTHENING CHINA'S DIPLOMATIC STRATEGY AND SOME FEATURES OF THE PERSONNEL POLICY REGARDING THE HEADS OF THE PRC DIPLOMATIC MISSIONS
Authors:   Russian State University for the Humanities, Pomozova Natal'ya B.
Published: January 2021

The article attempts to trace some features of the China diplomatic strategy in the context of the global confrontation between the United States and the PRC. Diplomacy is an essential foreign policy tool of any state. In the era of mass media and communication, diplomatic agents face new realities, while their role in implementing the foreign policy strategy is increasing due to the relevance of a new type of confrontation – the information and hybrid wars. Traditionally, the United States remained the leader in the number of diplomatic missions abroad; however, in 2019 China was ahead of its main competitor in that respect. The geographical choice in opening new diplomatic missionsis an indicator ofthe country’sforeign policy priorities. Thus,the work of the new Chinese embassies helped to reduce the number of countries recognizing the Republic of Taiwan down to 15. An analysis of the personnel policy regarding the heads of the diplomatic missions of the PRC in the “key” areas has revealed some features that affect the working style of the ambassadors. The factor of strengthening the influence of the PRC in reputable international organizations through its diplomatic agents, which has traditionally been the prerogative of the United States, also demonstrates the offensive ambitions of China’s foreign policy strategy.

Published: January 2021

The article presents Russian-Syrian cooperation after termination of the main phase of the counterterrorism operation, switching to political process and economic recovery of the country. The article considers Russian regional policy that is based on formation of “flexible” tactic unions. Economic interests of Turkey, Iran and China are analyzed as well. Those countries consider Syria to be an important element in the emerging oil and gas and logistic trans-border structure. At the same time, Syria itself is looking for a new model of building bilateral and multilateral relations not only in the Middle Eastern region but with countries of Eurasia.

Published: January 2021

Millet is grown in the large savanna region of Nigeria mostly in a system of intercropping with other crops. The study seeks to analyse the efficiencies of millet-based production pattern and its determining factors in the derived savanna zone of Nigeria. Data were collected from primary sources using a structured questionnaire administered to the selected 196 millet-based farmers. Input oriented Data Envelope Analysis (DEA) and Tobit regression model were used to achieve the aims of the research. The mean Technical Efficiency (TE) of the millet and sorghum (MS), millet-sorghum-groundnut and cowpea (MSGC), millet-sorghum and groundnut (MSG), millet-sorghum and cowpea (MSC) and sole millet (SM) were 40, 21, 38, 32 and 48 % respectively. This suggests that in the short run, there are gaps of 60, 79, 62, 68 and 52 % to increase the efficiency levels respectively. This may be through enhanced use of accessible production inputs. The mean Allocative Efficiency (AE) for the millet-based farmers was 0.56, 0.55, 0.67, 0.56 and 0.91 for MS, MSGC, MSG, MSC and SM respectively. The results revealed that estimates of factors that influence millet-based farmers’ systems have different degrees of statistical significance and where the level of significance is the same, the magnitude and direction were not the same. The numbers of millet-based farms operating under constant, increasing, and decreasing returns to scale were also estimated. The result of sensitivity analysis for an optimum plan for millet-based inputs used showed that land, seed, labour, fertilizer and agrochemicals are not limiting resources to obtain optimal farm plan. These results indicate the units needed to be decreased from various millet farms respectively for optimal production. More youths should be encouraged by the government and private organizations by providing them with necessary incentives to engage in farming to minimize inefficiency associated with older aged farmers.
Revisión sobre los efectos de estudiar con música de fondo y sobre los efectos del entrenamiento musical en el aprendizaje
Authors: Cantú Cervantes Daniel
Published: January 2021

Se analizaron dos aspectos importantes de la música en el aprendizaje, por un lado, los efectos de la música de fondo durante el estudio académico en los estudiantes, y por otra parte, los efectos del entrenamiento musical en el aprendizaje. Se realizó una revisión bibliográfica en las bases de datos ScienceDirect, Scopus, PubMed y Google Scholar sobre las palabras clave: música de fondo, música aprendizaje, música estudio y entrenamiento musical; incluyendo artículos, capítulos y libros especializados en inglés y español publicados desde 1998 hasta mayo de 2020, con el propósito de exponer un panorama actualizado sobre los hallazgos y efectos del impacto de la presencia de música en el estudio académico y sobre las ventajas que brinda el entrenamiento musical respecto al aprendizaje. La evidencia sugiere que música de fondo perturba más la concentración en el estudio académico que la condición de silencio. Por otro lado, se identificó que los efectos benéficos del entrenamiento musical son consistentes con cuatro áreas académicas: el lenguaje, cálculo mental, representación de artes escénicas y la orientación espacial manual.

La Teoría del Capital Humano y su incidencia en la Educación. Un análisis desde la perspectiva mexicana
Authors: Silva Payró Martha Patricia , García Martínez Verónica , Ramón Santiago Pedro
Published: January 2021

El presente trabajo es una propuesta reflexiva sobre la Teoría del Capital Humano y su relación con la educación, tema que ha sido abordado desde diferentes perspectivas, sobre todo la económica, y posteriormente la sociológica. Se expone de manera sucinta la evolución de esta perspectiva teórica para coincidir en su injerencia con la educación. Se abordan además algunas consideraciones del caso de México. El objetivo fue analizar la manera en que el Capital Humano está invariablemente relacionado con la educación y la formación académica. Se concluye que el crecimiento económico de la persona depende no sólo de la educación recibida, sino de otros elementos ajenos al mismo individuo, así como que la concepción de que existe una relación directa proporcional entre educación y crecimiento económico ha cambiado a través del tiempo, y que una mayor formación educativa no garantiza el éxito.
L’informatique pour améliorer les soins infirmiers : le pouvoir inexploité des données collectées par le personnel infirmier
Authors: Picard Christopher , Kleib Manal
Published: January 2021

Dans le domaine des soins de santé, la collecte de données revêt une importance capitale pour guider les décisions cliniques, la planification des ressources et le suivi de l’efficacité des soins. Le Système canadien d’information de gestion des départements d’urgence (SIGDU) et l’Échelle canadienne de triage et de gravité pour les départements d’urgence (ÉTG) sont les principaux outils utilisés pour collecter ces données. Malgré le fait que les infirmières des urgences se servent de ces outils tous les jours pour recueillir des données utiles sur les patients et les soins de santé, on ignore la compréhension qu’elles ont de l’objectif et de l’incidence de cette collecte de données. À cause de leur connaissance limitée de l’informatique et de leur faible représentation dans la recherche et les initiatives stratégiques du domaine des technologies de l’information et de la communication (TIC), les infirmières des urgences risquent de ne pas tirer pleinement profit des avantages de la technologie. L’Association nationale des infirmières et infirmiers d’urgence (ou NENA, pour National Emergency Nurses Association) est bien placée pour exercer le leadership nécessaire afin que les infirmières ne soient pas seulement chargées de recueillir les données, mais qu’elles sachent aussi les utiliser en maximisant leur capacité à faire progresser la pratique des soins infirmiers d’urgence grâce à l’informatique.
Unintelligent Decision-Making?
Authors: Luna Samantha , Redlich Allison
Published: January 2021

The disclosure of evidence, primarily from the prosecutor to the defense (i.e., discovery) is key to a fair and just legal system. Restrictive discovery policies have been criticized for contributing to innocent defendants pleading guilty (Alkon, 2014) and to uninformed plea decisions (Friedman, 1971). Open-file policies, in which prosecutors broadly share evidence with the defense, are a leading reform to address these issues. This study investigated the impact of guilt and access to discovery information (with or without exculpatory evidence) on plea decisions. We hypothesized that, in comparison to their counterparts, participants who had access to all of the evidence (i.e., those in open-file condition) and participants who were innocent would rate the evidence against them as significantly weaker, their probabilities of conviction at trial as significantly lower, and would be less likely to take the plea deal. We also hypothesized that ratings of evidence strength and probability of conviction would mediate expected relations between the plea decision and conditions. One-hundred participant-defendants were randomly assigned to open- vs. closed-file and guilt vs. innocence conditions, and asked to review case materials that either contained full or partial discovery. They were then asked to rate the strength of the evidence against them, their probability of conviction, and to accept or reject a plea offer in a hypothetical case. Defendant guilt and access to discovery information impacted perceived evidence strength, which subsequently impacted plea decision-making. Our findings indicate that access to discovery information indirectly impacted defendants’ plea decisions.

On Diversification of Ore Mining Complex as Direction for Development of Depressive Economic System
Authors: Titova A.V. , Golik2 V.I.
Published: January 2021

The priorities for the development of the industrial complex are to compensate for market risks by dispersing activities into several types of business with the development of new products, the cost of which is reduced due to the use of the existing infrastructure. The prospects of mining enterprises of the North Caucasus in the implementation of production diversification are outlined. The results of substantiating the effectiveness of diversification at various volumes of ore mining in the conditions of the unprofitable Sadonsky lead-zinc plant with a graphical interpretation of economic calculations are given. The results of calculating the efficiency of involving substandard technogenic ores in the development, obtained by comparing alternative options that differ in the size of reserves, are given. An equation for the balance of values is proposed, which establishes the relationship between the volume of production and the completeness of extraction of reserves of deposits during the development of reserves of substandard ores and wastes. To assess the effectiveness of actions during diversification, an integral indicator of flexibility is proposed and the method of marginal analysis is used to reduce the uncertainty of situations. A graph of the relationship between the volume of ore production, economic indicators and the break-even point is shown. Okha-characterized the mineral resource base of diversified enterprises and diversification products for consumption by related industries. It is shown that the diversification of the ore mining complex is still a little used reserve for the development of the economic system of the depressive type.

Rock Movement in Tectonic Zones. Mining Activities and Rock Pressure Management in the Norilsk-Kharaelakh Fault Area
Authors: Kirillov S.G. , Ufatova Z.G. , Khrushchev I.F. , Bashirov K.A.
Published: January 2021

The article describes the rock mass state within the boundaries of the Skalistiy mining allotment. The ore mass within the mine field was found to preserve its rock-bump hazard and show high mobility in the impact zone of the Norilsk-Kharaelakh Fault and the associated high failure potential manifested as roof cavings. Based on the monitoring results along underground profile lines, it was concluded that the displacement process is currently at its initial stage. Moreover, the maximum subsidence in the central part of the profile line is about 3 times higher (up to 35 mm) than in other areas. This is caused by immediate proximity of this zone to the Norilsk-Kharaelakh Fault. Assessment of the bump hazard level of this rock mass with the help of the Prognoz-2 instrument that was performed by the rock-bump forecasting and control teams of the mine and the Norilskshakhtstroy company, showed the 'Not Hazardous' category in all cases. However, the progress of mining operations towards the Norilsk-Kharaelakh Fault may lead to deterioration in the condition of mine workings. This can be manifested through rock exfoliation from the walls of the advance workings of the safety layer in highly and extremely faulted rocks. In addition, permanent workings, which are one of the most critical structures of the production level and which will be used until the development of the deposit area adjacent to the Norilsk-Kharaelakh Fault is completed, will be maintained in increasingly difficult conditions. The article describes recommendations for mining operations in the fault area with account for the current mining and geomechanical situation and the potential for its change.

Authors: Rodriguez-Camejo Jeremy Swan , García-Ramos Tania , Santiago-Estrada Sara
Published: January 2021

En este artículo se discute el valor de la teoría de la subjetividad, desde la Perspectiva Histórico Cultural (PHC), para el campo de la psicología clínica y la psicoterapia.  Para esta discusión se explora cómo la traducción y difusión de la obra de Vygotsky en Occidente se vio afectada por diversos factores históricos e ideológicos que impidieron que la PHC se extendiera al campo de la psicología clínica.  Además, se discute la propuesta teórica de la subjetividad, la psicoterapia y la Epistemología Cualitativa que elaboró González Rey como una alternativa para generar un puente entre la PHC y la psicología clínica.  Al final se discuten aspectos que deben elaborarse en la propuesta de González Rey en su implementación en el campo clínico.
Kajian Tentang Rancang Bangun Benteng Kompeni di Jepara
Authors: Abbas Novida
Published: January 2021

Salah satu sarana pertahanan yang berasal dari masa kolonial di Jawa adalah benteng-benteng Belanda, yang beberapa di antaranya masih dapat disaksikan bekas-bekasnya hingga kini. Keberadaan benteng-benteng tersebut menyiratkan adanya konflik antara kelompok-kelompok masyarakat di Nusantara melawan kolonial, yang memaksa pihak kolonial untuk mendirikan berbagai sarana pertahanan guna menangkal upaya perjuangan rakyat tersebut. Di antara sejumlah bekas benteng Belanda di Jawa, salah satu yang masih dapat disaksikan adalah sebuah benteng yang terdapat di Jepara. Benteng yang dikenal dengan sebutan Benteng VOC atau Benteng Kompeni ini terletak di wilayah Dusun Ujung Batu, Desa Ujung Batu, Kecamatan Jepara, Kabupaten Jepara, Propinsi Jawa Tengah. Tepatnya benteng tersebut terletak di puncak sebuah bukit yang menghadap ke Laut Jawa.
Studi Permukiman Kuna di Indonesia Melalui Pendekatan Multidisiplin

Penelitian di bidang arkeologi akhir-akhir ini semakin berkembang pesat seirama dengan perkembangan ilmu pengetahuan dan teknologi. Perkembangan itu tidak saja tampak dari pemilihan situs, penerapan teori dan metodologi, penggunaan metode dan teknik, melainkan juga pemilihan dan penampilan subjek penelitiannya. Arkeologi yang pada awal perkembangannya hanya dikenal sebagai hobby, tidak mengherankan jika pusat perhatian mula-mula tertuju pada benda-benda yang mempunyai nilai seni. Di dalam perkembangan selanjutnya para pemerhati tidak hanya tertarik pada benda yang bernilai seni, tetapi juga yang tidak bernilai seni bahkan mencapai taraf perhatian terhadap komplek-sitas hubungan antar benda yang dapat mencerminkan berbagai aspek kehidupan manusia masa lampau.
Escudo de Blumer: signo diagnóstico de la diseminación a distancia del cáncer gástrico difuso

Introducción. Se conoce como escudo de Blumer al engrosamiento neoplásico del fondo de saco de Douglas,palpable al tacto rectal como una protrusión en forma de resalte, presente en pacientes afectados por carcinomas con infiltración difusa. A pesar de haber sido descrito hace más de un siglo, se trata de un proceso diagnosticado infrecuentemente y con escasa mención en la literatura científica. Es preciso tener un alto nivel de sospecha clínica para correlacionar los síntomas pélvicos con la presencia de un tumor, habitualmente gástrico.Casos clínicos. Presentamos dos pacientes con hallazgo de escudo de Blumer, asociado a cáncer gástrico difuso, uno como diagnóstico primario de enfermedad metastásica y otro como recidiva de la enfermedad, meses después de ser operado. Ambos casos presentan un complejo proceso diagnóstico, en el que prima la sospecha clínica, apoyado sobre pruebas de imagen como tomografía computarizada y resonancia nuclear magnética, ya que tanto las biopsias obtenidas por endoscopia, como las biopsias intraoperatorias fueron negativas. Discusión. En el escudo de Blumer, las células tumorales infiltran el fondo de saco de Douglas de forma difusa por debajo de la serosa, sin necesidad de que existan implantes macroscópicamente visibles en el peritoneo visceral.La infiltración tumoral puede afectar extrínsecamente al recto, causando una estenosis del mismo, lo que produce sintomatología pélvica inespecífica, como tenesmo rectal y proctalgia. Por lo tanto, este ominoso proceso debe ser sospechado en pacientes con sintomatología pélvica, que presenten o hayan presentado cáncer gástrico.
Mortalidad perioperatoria de pacientes sometidos a apendicectomías en el régimen contributivo de Colombia

Published: January 2021

Introducción. La mortalidad perioperatoria se considera una de las herramientas clave para medir la fuerza del sistema de salud de un país en el área quirúrgica. Actualmente, no se cuenta con las cifras totales de las apendicectomías realizadas en nuestro pais, a pesar de ser un procedimiento quirúrgico extremadamente común. Métodos. Estudio de cohorte retrospectivo con datos de pacientes de todas las edades, reportados como afiliados al sistema de salud contributivo de Colombia y a quienes se les realizó una apendicectomía entre el 1° de enero de 2011 y el 31 de diciembre de 2016. La información se obtuvo de bases de datos nacionales y se procesó a partir del cálculo de variables, como la tasa de mortalidad perioperatoria y el volumen quirúrgico, estimando una tasa de mortalidad a treinta días, por sexo, grupo etario y región geográfica. Resultados. Entre las 231.570 apendicectomías que se identificaron, se halló una mayor tasa de mortalidad perioperatoria en el grupo etario de hombres mayores de 80 años con 17,3 %. La región oriental presentó la menor tasa de mortalidad con 0,01 %. El mayor volumen quirúrgico se presentó en el año 2012 y el menor en el año 2016. Discusión. La tasa de mortalidad de apendicectomía en diferentes grupos etarios es similar a la de otros países de ingresos medios y bajos, en tanto que la mayor heterogeneidad de la tasa de mortalidad entre las diferentes regiones, se percibe en los grupos de menores de un año y de mayores de 65 años. Este estudio se constituye como una aproximación inicial a la tasa de mortalidad en apendicectomías realizadas en Colombia.
Las palabras del año
Authors: Bejarano Castro Mónica
Published: January 2021

Según un estudio de la Real Academia Española (RAE), entre las diez palabras que más dijimos en los países hispanohablantes en 2020 están cuarentena y pandemia, seguidas de coronavirus, confinamiento y contagio. Las otras cinco que completan esa lista fueron distanciamiento, mascarilla, teletrabajo, asintomático e incertidumbre.

Por el contrario, el Oxford English Dictionary no pudo escoger su tradicional palabra del año, porque consideraron que en el 2020 el lenguaje se adaptó <> a un año sin precedentes, acumulando un nuevo vocabulario colectivo.

Authors:   RSC Energia, Tsygankov Oleg S.
Published: January 2021

The actualization of attention to the Moon with the aim of achieving and involving it in the production and economic turnover of the Earth’s civilization is declared as the prevailing trend in modern space activity by the scientific community. The author was a direct participant in the testing of the crew’s actions on the lunar surface in the framework of the domestic program N1/L3 in 1969-1974. He combines the results obtained at that time with half a century of practical experience in outer space at geo-orbital stations. Also he sets out his views on the content, features and means of labor at the initial stage of moon exploration, and also considers the moon as an object of geopolitics.
A Ramjet Relativistic Engine - a Hypothesis for Discussion
Authors:   Institute of Nuclear Research, Senkevich Alexander P.
Published: January 2021

In this paper, the engineering and scientific community is invited to consider and discuss the possibility of developing and constructing a ramjet engine for movement in the interstellar medium when the speeds of an aircraft are close to the speed of light. The idea is based on existing developments in high energy physics and accelerator technology. For interstellar flight, a motion scheme is proposed using accelerated relativistic high-energy protons to create efficient jet engines based on accelerating superconducting structures. The proposed scheme is based on the existing developments in the field of accelerator technology, using superconducting resonator systems, klystrons and high-frequency generators. The use of the impulse of the relativistic motion of charged particles is proposed as a hypothesis for discussing the design of a direct-flow engine for motion in the interstellar medium.

This research aims to determine the perceptions of new students on the implementation of zoning-based PPDB (New Learner Admission Activities). The method in this research was mixed-method approach. Primary data was obtained through distributing questionnaires filled out by students. Samples were taken using purposive sampling technique in five cities, including Bandung, Surakarta, Surabaya, Pontianak and Serang. The data analysis technique used the Miles and Huberman model. The results show that the school which initially received the favourite label is still the favourite one because of the facilities and infrastructure and the implementation of the existing learning process in the school. The zoning system based on student perceptions does not reduce enthusiasm for learning. The zoning-based PPDB for junior high school and senior high school is more guaranteed for students who live close to the school to get the target school. The zoning system has been well implemented in four cities, including Surabaya, Bandung, Surakarta and Pontianak. In addition, the zoning system can save money.
