THE PROBLEM OF THE US MONETARY AND FINANCIAL HEGEMONY IN THE MODERN WORLD: BASIC INSTRUMENTS AND CHANNELS OF INFLUENCE
Authors: Muzlova N.N. , Latypov A.A.
Published: March 2021

The purpose of the study is to determine the role of the USA dollar in the modern world and consider the monetary and financial instruments used by the United States to maintain its economic and political hegemony, as well as the possible consequences of using these instruments. To achieve this goal, the following tasks were set in the work: to study the economic history of the dominance of the dollar, to determine the impact of monetary policy and financial instruments of the United States on the world economy, to analyze the role of the IMF in maintaining the financial hegemony of the United States. Scientific hypothesis of the study is that the dollar and the financial institutions of the United States are key components of the modern economic world order and substantiate the monetary and financial hegemony of the United States, which consists in the ability of the United States to control the world economy, influence the economic situation in different countries, and implement its geopolitical goals with the help of economic instruments. This article contains an analysis of the US foreign economic policy aimed at the maintaining the primacy of the United States in both the sphere of world monetary and financial relations and in the political dimension. The article provides a summary of the most important events in the economic history of the dollar: the collapse of the Bretton Woods system and the 2008 global financial crisis. Particular attention is paid to the financial instruments of US foreign policy influence, in particular, access to financial markets, investments, as well as the use of the IMF as an instrument for achieving US foreign policy goals. The scientific novelty lies in the approach to US geoeconomics, namely the imposition of the economic dimension on the political one. As a result, it is concluded that the US dollar, the Federal Reserve System and the IMF are indeed the most authoritative and significant components of the existing world economic system, using which the United States acts as a monetary and financial hegemon and has a wide range of tools to control the global financial system.
ON CONTROLLING FAKES, DEEPFAKES, FAKE ACCOUNTS IN THE INTERNET
Authors: Krasovskaya N.R. , Gulyaev A.A.
Published: March 2021

In the information society, information is the basis for decision-making at all levels. However, in post-truth society, fake news and deepfakes are often created and distributed via artificial intelligence technologies. Confidence in information is gradually lost, and the creation of a way to accurately recognize its authenticity will become a scientific and technical discovery. The problem of identifying fake information also affects the identification of its primary source, which often uses fake accounts. Counties are concerned about the security of the information space. They are attempting to control the spread of fakes, deepfakes, and the creation of fake accounts in the Internet. Control can be global and nationally bureaucratic. Many countries, to various extents, are trying to control the Internet through national bureaucratic measures. However, everyone realizes that there are not enough global measures to control the Internet.

Monitoring Water Resources through a Bayesian Optimization-based Approach using Multiple Surface Vehicles: The Ypacarai Lake Case Study
Authors: Peralta Samaniego Federico , Toral Marín Sergio , Gutierrez Reina Daniel
Published: March 2021

Bayesian optimization is a popular sequential decision strategy that can be used for environmental monitoring. In this work, we propose an efficient multi-Autonomous Surface Vehicle system capable of monitoring the Ypacarai Lake (San Bernardino, Paraguay) (60 km2) using the Bayesian optimization approach with a Voronoi Partition system. The system manages to quickly approximate the real unknown distribution map of a water quality parameter using Gaussian Processes as surrogate models. Furthermore, to select new water quality measurement locations, an acquisition function adapted to vehicle energy constraints is used. Moreover, a Voronoi Partition system helps to distributing the workload with all the available vehicles, so that robustness and scalability is assured. For evaluation purposes, we use both the mean squared error and computational efficiency. The results showed that our method manages to efficiently monitor the Ypacarai Lake, and also provides confident approximate models of water quality parameters. It has been observed that, for every vehicle, the resulting surrogate model improves by 38%.

Published: March 2021

Students who are working on their final project often faced with various problems and pressures. They need to build self-efficacy to be able to increase confidence in achieving something. Self-efficacy is an individual’s belief in their ability to organize and take steps in solving certain problems or tasks. Individuals with high self-efficacy view difficult tasks as challenges to face rather than as threats to avoid. Respondents are highly committed to achieving its goals, respondents will also invest a high level of effort and strategic thinking to deal with failure. Resilience is the ability to thrive in the face of adversity in every individual whilst facing problems or pressure. By increasing resilience, humans can develop life skills such as communicating, realistic abilities in making life plans, and being able to take the right steps for their lives. This study was conducted to determine whether self-efficacy has an effect on resilience. The research design used in this study is a quantitative research design with a sample of 75 people and the population of this study is students who are working on a thesis. The data were first analysed for validity, reliability, and followed by simple regression analysis. The results showed that self-efficacy had an effect on the resilience of 30,5% and a significant value of p = .000 (p<0.05), testing the effect of the dimensions of self-efficacy on resilience showed results that strength has the greatest influence on resilience.

Prawo w filmie jako przejaw estetyki prawa i szczególny przypadek kierunku prawo i literatura
Authors: Zeidler Kamil
Published: March 2021

If we put together and systematize research streams: law in film, law and literature, and aesthetics of law, it is easy to reach the conclusion that we are dealing with related subjects, with a certain overlap in research areas. The broadest term is aesthetics of law, whose scope covers the entire law and literature movement, meanwhile law in film is a more detailed aspect of the latter. Systematizing the aesthetics of law, we can close it in three aspects: the external one, the internal one, and the one called ‘law as a device for aesthetization’. The aesthetics of law in the external aspect deals with manifestations of law, legal inspirations, legal themes, symbols, signs, which were represented through centuries in fine arts. The subject of the aesthetics of law in the internal aspect is the law itself. The third aspect of the aesthetics of law focuses on law as a device for aesthetization of daily life. In the law and literature movement, the reflections concern either the inclusion of legislative and legal content in literary works (law in literature), or the literary, including aesthetic, value, of normative instruments, and more broadly, also other acts of applying the law (law as literature). A special case of this research stream is legal cinematography, where a film prepared on the basis of a screenplay is treated as a kind of narrative, justifying the statement that law in film further develops the law and literature movement. The practical aspect of such research – of legal aesthetics, law and literature, and law in film – concerns mainly the significance and influence on legal awareness, and on shaping the attitudes towards law. The key thing here is approaching the problem of influencing legal awareness through other means than the text of a normative instrument alone.

Published: March 2021

This article presents a scientific-discourse and overview systematically on the word-formation that how the impacts and strategies of morphology produce the significant enrolment in the productive-pedagogies to teach and enhance the different parameters and paradigms of vocabulary’s re-structure and lexicography. The determinations of researchers define and describe the mechanism of affix morphemes (derivational and inflectional) in the formation of new words with the complete lexical-semantic meaning and syntactic-structure, which are developed through the general morphological processes in the morphosyntax. This research attempt intends to specify the strategies, knowledge, and information employed by L2 students of tertiary level when they face new words while reading the texts. Even learners have a tendency to ignore a large amount of new vocabulary they encountered due to poor enhancement of the weak vocabulary awareness and immature and traditional pedagogical course policies at their schooling. They must beware of morphological misanalysis and false-etymology. Therefore, the article advocates instructors that L2 students to individual’s phonological awareness, knowledge of orthography (sound-symbol relationships, letter patterns and spelling regularities), knowledge of vocabulary, and visual memory skills. Learners are advised to aware of the enhancement of word theories and all kind of word formations and processes for their productive reading performances, creative writing drafts, figurative expressions and critical thinking lexicologically at the course level.
Niezwykła historia zwyczajnego kasztanowca
Authors: Walas Łukasz
Published: March 2021

Kasztanowiec zwyczajny (Aesculus hippocastanum L.), popularne drzewo ozdobne, został sprowadzony do centralnej Europy z Istambułu. Pojawił się pod koniec XVI wieku w Wiedniu, Bolonii, Padwie i Pradze. Szybko stał się popularny i w krótkim czasie dotarł do Anglii, Niemiec i Francji. W Polsce po raz pierwszy znalazł się prawdopodobnie w XVI wieku, sprowadzony przez króla Stefana Batorego. Naturalne stanowiska tego gatunku w górzystych obszarach Bałkanów zostały odkryte dopiero w XIX w. Występuje on tam w rozproszonych populacjach o zmniejszającej się liczebności. Ten reliktowy gatunek jest bardzo ceniony w parkach ze względu na walory dekoracyjne i niewielkie wymagania siedliskowe; ma również znaczenie w przemyśle farmaceutycznym. Inwazja motyla, szrotówka kasztanowcowiaczka, spowodowała spadek wartości dekoracyjnych oraz zagrożenie kasztanowców w całej Europie. Również przewidywane zmiany klimatu mogą stanowić niebezpieczeństwo dla tego gatunku.
Proces wymiany zębów u wybranych grup ssaków w ujęciu ewolucyjnym
Authors: Muniak Paweł
Published: March 2021

Wymiana uzębienia u ssaków to jeden z najważniejszych procesów ewolucyjnych w tej grupie kręgowców. Pierwsze ssaki wykazywały dużo cech pierwotnych, odziedziczonych po gadzich przodkach. Już na bardzo wczesnym etapie zęby zróżnicowały się na siekacze, kły, przedtrzonowce i trzonowce, pojawiła się też tendencja do redukcji liczby zębów. Przełomowe znaczenie miało powstanie difiodoncji, czyli występowania dwóch pokoleń zębów, mlecznych i stałych, co jest charakterystyczną cechą ssaków, w odróżnieniu od polifiodontycznych gadów. Ewolucja wymiany uzębienia szła w kierunku coraz mniejszej liczby wymienianych zębów. Celem niniejszego artykułu jest przybliżenie Czytelnikom głównych etapów zapoczątkowanego przed ponad 200 mln lat procesu, który doprowadził do znacznego zróżnicowania zarówno wzorów uzębienia, jak i typów wymiany zębów, co obserwujemy u współczesnych ssaków.

Authors: Galvin Jeff , Strudd Sarah
Published: March 2021

The Sonoran Desert Network (SODN) conducted a vegetation mapping and characterization effort at the two districts of Saguaro National Park from 2010 to 2018. This project was completed under the National Park Service (NPS) Vegetation Mapping Inventory, which aims to complete baseline mapping and classification inventories at more than 270 NPS units. The vegetation map data were collected to provide park managers with a digital map product that meets national standards of spatial and thematic accuracy, while also placing the vegetation into a regional and national context. A total of 97 distinct vegetation communities were described: 83 exclusively at the Rincon Mountain District, 9 exclusively at the Tucson Mountain District, and 5 occurring in both districts. These communities ranged from low-elevation creosote (Larrea tridentata) shrub-lands spanning broad alluvial fans to mountaintop Douglas fir (Pseudotsuga menziesii) forests on the slopes of Rincon Peak. All 97 communities were described at the association level, each with detailed narratives including lists of species found in each association, their abundance, landscape features, and overall community structural characteristics. Only 15 of the 97 vegetation types were existing “accepted” types within the National Vegetation Classification (NVC). The others are newly described and specific to Saguaro National Park (and will be proposed for formal status within the NVC). This document is Volume II of three volumes comprising the Saguaro National Park Vegetation Mapping Inventory. This volume provides two-page summaries of the 97 associations identified and mapped during the project, and detailed in Volume I. Summaries are presented by district, starting with the Tucson Mountain District. These summaries are abridged versions of the full association descriptions found in Volume III.

Published: March 2021

The researcher investigates the conflict in photographs of two Afghani newspapers daily
Kabul Times and daily Weesa related to Afghanistan war in this research. The time period
assigned for the study was six months — from July l, 2018 to December 31, 2018. This
quantitative content analysis of the photographs, on one hand, depicted the current war in the
country; it helped to determine whether the photographs conform to the perspective of peace
and war journalism approaches, on the other. Such an approach seemed significant for know
how the visual depictions of Afghanistan war were conducted and what appropriate
conceptual and methodological tools existed in this regard. The finding showed that Kabul
Times contributed more peace frames than war in pictures while covering war in the country.
Weesa newspaper has given the more space to war frame instead of peace in its pictures.
Overall, the results of the study suggest that peace framed pictures were comparatively more
than the war framed pictures, in terms of contents in particular. So, the study seems to be very
optimistic about the outcome of the ongoing peace negotiations between Taliban and USA
and this study recommends that the future research in the area must focus on the media visual
frame of intra-negotiations between the government and Taliban.

Indonesia is one of the countries which have the best Gambier quality in the world. Those are a few areas in Indonesia which have best gambier quality such as Aceh, Riau, North Sumatera, Bengkulu, South Sumatera and West Sumatra. Kabupaten 50 Kota is one of the regencies in west Sumatra that supplies gambier in Indonesia. The gambier leaf selection is mostly done by manual inspection or conventional method. The leaf color, thickness and structure are the important parameters in selecting gambier leaf quality. Farmers usually classify the quality of gambier leaves into good and bad. Computer Vision can help farmers to classify gambier leaves automatically. To realize this proposed method, gambier leaves are collected to create a dataset for training and testing processes. The gambier image leaves is captured by using DLSR camera at Kabupaten 50 Koto manually. 60 images were collected in this research which separated into 30 images with good and 30 images with bad quality. Furthermore, the gambier leaves image is processed by using digital image processing and coded by using python programming language. Both TensorFlow and Keras were implemented as frameworks in this research. To get a faster processing time, Ubuntu 18.04 Linux is selected as an operating system. Convolutional Neural Network (CNN) is the basis of image classification and object detection. In this research, the miniVGGNet architecture was used to perform the model creation. A quantity of dataset images was increased by applying data augmentation methods. The result of image augmentation for good quality gambier produced 3000 images. The same method was applied to poor quality images, the same results were obtained as many as 3000 images, with a total of 6000 images. The classification of gambier leaves produced by the Convolutional Neural Network method using miniVGGNet architecture obtained an accuracy rate of 0.979 or 98%.

This study aims to (1). To find out the process of learning mathematics during the Covid-19 pandemic. (2). To find out what the headmaster was doing in learning mathematical during the Covid-19 Pandemic. The research method used is using descriptive qualitative research method. Data collection techniques used interview techniques and documentation. The subject in this research is the principal, mathematics teacher and four students who are randomly selected. The results obtained from this study indicate (1). The process of learning mathematics during the Covid-19 pandemic described modules or material summaries and assigning assignments to student. (2). To see what the headmaster did in learning mathematical during the Covid-19 pandemic. Thus suggested that teachers should able to prepare the material properly so that students do not get bored with online learning. Students must take advantage of their free time to always explore the material that the teacher has distributed. For subsequent researchers who conduct research related similar, we use a broader subject.
Peculiaridades de la poesía como documento histórico. Algunos casos contemporáneos españoles
Authors: Muro Miguel Ángel
Published: March 2021

Pretendo reflexionar en estas páginas sobre la compleja entidad de la poesía a la hora de ser tomada como documento histórico y, para poder precisar algo más esta cuestión, planteo la posibilidad o la conveniencia de que realizaciones poéticas concretas de la postguerra española, como las de Claudio Rodríguez o la denominada poesía del “realismo social” puedan ser tomadas como material historiográfico, atendiendo al beneficio que ello podría suponer y a las dificultades que entrañaría tal adopción para el historiador.
¿Cargada de futuro? Del manifiesto al eslogan
Authors: Bagué Quílez Luis , Baños Saldaña José Ángel
Published: March 2021

“La poesía es un arma cargada de futuro” es el título de una de las composiciones de Cantos iberos (1955), de Gabriel Celaya, pero también uno de los lugares comunes más habituales en la poesía española de posguerra. En este artículo nos centraremos en la pervivencia del lema de Celaya en los autores de las últimas décadas del siglo xx y comienzos del siglo XXI. Dentro de este contexto cabe distinguir tres actitudes principales: la adaptación del mensaje de transformación social a la perspectiva desencantada del compromiso contemporáneo; la conversión del dictum de Celaya en un eslogan desvitalizado, no muy lejos de la retórica comercial; o la resemantización de las viejas consignas sociales en un nuevo entorno de insatisfacción cívica.
Intermedialidad y disidencia en "Última rumba en La Habana"
Authors: Tennenini Roberta
Published: March 2021

En la novela Última rumba en La Habana (2001), Fernando Velázquez Medina explora las facetas más oscuras y miserables de la sociedad cubana del periodo especial por medio de una construcción discursiva de tipo intermedial. La obra se enmarca dentro del llamado “realismo sucio” y pone en escena el monólogo de una jinetera cuyo sueño es exiliarse. Las referencias literarias, musicales, cinematográficas y artísticas que salpican la novela y arman la narración contribuyen a deconstruir el metarrelato revolucionario que la protagonista critica. A tono con los planteamientos de Mitchell, Rajewsky y Müller sobre la intermedialidad y siguiendo las reflexiones que Foucault dedica al poder, el presente artículo analiza el alcance contrahegemónico de la intermedialidad.
Humanización y conocimiento: pilares de la Enfermería
Authors: Alonso-Nates Rosa
Published: March 2021

Ya es paradójico que, en una profesión eminentemente humana, basada principalmente en el trato directo con personas, con humanos, en su cuidado, hablemos de humanidad.Dicen que cuando se habla de la esencia de algo, buscándolo, es porque no se ve, no está ahí, no se nota. Recordar la humanidad en Enfermería es como hablarde administrar en la Administración.¿Será que precisamente ahora, con este tiempo tan adverso,lo echamos más en falta?, ¿o será que la humanidadestá en descenso en la escala de valores?Nuestra profesión puede demostrar que es un valor en alza, que lo apreciamos todos: “La humanidad es asunto de todos”, como la salud o la educación.Y de lo universal vamos a lo particular, a la profesión de enfermera y la humanidad entendida como sensibilidad, comprensión, compasión con las desgracias ajenas y el cuidado que necesite cualquier persona, cualquier ser humanopor ello.

Published: March 2021

Introducción: Los pacientes con enfermedad renal crónica avanzada ven gravemente afectada su calidad de vida lo que a menudo puede implicar riesgo de muerte. Objetivo: Evaluar el impacto de la intervención de enfermería en el autocuidado de pacientes con enfermedad renal crónica avanzada de un hospital público. Material y Método: Estudio pre experimental de corte longitudinal y prospectivo. La muestra incluyó a 60 pacientes en estadíos 3b, 4 y 5 de la enfermedad renal crónica, a quiénes se aplicó 3 tipos de cuestionario previamente validados, antes y después de la intervención de enfermería que consistió en tres sesiones educativas y asesoramiento en consulta externa. Las tres dimensiones que se tomaron para la investigación fueron: conocimiento sobre la enfermedad, autocuidados y adherencia farmacológica. Para el análisis de datos, en conocimiento se utilizó la prueba de Wilcoxon; en autocuidados, la prueba T de Student, y la prueba de McNemar para medir la adherencia. Para el procesamiento de resultados se utilizó el software SPSS v.20. Resultados: Tras la intervención, el conocimiento sobre autocuidado se incrementó hasta un 71,7%, con relación al momento pre-intervención. Igualmente, el nivel de autocuidado aumentó tras la intervención a 72%. Respecto a los adherentes al tratamiento farmacológico, antes de la intervención eran el 5%, posteriormente se incrementó hasta el 65%. Conclusión: La intervención de enfermería basada en actividades educativas y de asesoramiento produce un impacto positivo en el autocuidado de pacientes con enfermedad renal crónica avanzada.

Introducción: La hemodiafiltración en línea post-dilucional es una variante de hemodiálisis que, según diferentes estudios puede aumentar la supervivencia de los pacientes. Inicialmente, y a diferencia de la hemodiálisis convencional, se utilizaban flujos de dializado muy elevados (hasta 700-800 ml/min); nuevos estudios cuestionaron la utilidad de elevar tanto este flujo en cuanto a eficacia depurativa. Objetivo: Analizar las diferencias producidas en Kt, Kt/V y volumen de infusión en esta técnica utilizando flujo de baño de diálisis a 600 ml/min y a 500 ml/min, así como evaluar la repercusión en el consumo de agua durante la sesión. Método: Se incluyeron 22 pacientes crónicos dializados con hemodiafiltración en línea post-dilucional en monitores Artis®. Se estudiaron 440 sesiones, 220 con cada flujo. Las variables estudiadas fueron edad, tiempo de permanencia en técnica, Kt, Kt/V y volumen de infusión. Resultados: De los 22 pacientes 7 son mujeres, la mediana de edad es de 79,5 años (rango 40-86) y la media de permanencia: 25,13±10,51 meses. Las medias con flujo de diálisis a 600 ml/min y a 500 ml/min fueron respectivamente: Kt:45,5±9,4 y 45,2±9,2 litros, Kt/V:1,52±0,33 y 1,51±0,33 y volumen de infusión: 21,84±4,50 y 21,94±4,51 litros. Influencia del flujo del líquido de diálisis en los parámetros de calidad de la hemodiafiltración en línea post-dilucional. Conclusión: Según nuestros resultados se puede dializar en hemodiafiltración en línea post-dilucional con flujos de dializado de 500 ml/min sin menoscabo de los parámetros de calidad de hemodiálisis.
