Teatro para la memoria: danzantes de pensamientos
Authors: Camelo Gómez Michael Steven , Jiménez Quenguan Myriam
Published: January 2021

Este artículo trata sobre el Teatro para la Memoria, proyecto desarrollado en Cumbal–Nariño (frontera colombo–ecuatoriana) (2016). Su propósito es fortalecer el legado ancestral en personas jóvenes indígenas a través de la danza y el teatro; en este sentido, sustenta la vigencia e impacto del Teatro del Oprimido de Augusto Boal, heredero de la pedagogía de Paulo Freire. Bajo un paradigma cualitativo, de estudio etnográfico y de acción participación, se trabajó con grupos focales que comunicaron creativamente lo que son, hacen y sienten por medio de bitácoras, mingas de pensamiento, memorias visuales, montajes escénicos y la creación de la obra El retorno de las perdices. Los resultados permiten afirmar que propuestas artísticas con jóvenes de cualquier comunidad cultural generan mayor sentido de pertenencia de su cuerpo, mente y voz para expresarse ante la sociedad, reivindicar su lugar en el mundo y otorgar mayor sentido a la historia de los pueblos. Esta experiencia se divulgó en distintas ciudades de Colombia, compartiendo la espiritualidad, historia y fuerza de los Pastos, también se pronunciaron algunas desigualdades, ya que al ser fronterizos y aislados de la capital, han padecido diferentes formas de inequidad. Finalmente, se reflexiona sobre la técnica teatral del Teatro-Danza, que en este caso integra etnoliteratura, arte y educación propia para apoyar una transformación positiva de problemas.
Enrique Moreno y de los Arcos (1943-2004). La vida de un pedagogo auténtico
Authors: Garcia Cerda Pólux Alfredo
Published: January 2021

En el presente texto se esboza el primer perfil biográfico de un pensador importante para la pedagogía mexicana. Para su realización, se usó el método histórico de comprensión aplicando las nociones hermenéuticas de texto y narrativa biográfica. La intencionalidad de su vida, su pensamiento y su obra se reconstruyeron a través de una primera localización e interpretación de tres grandes fuentes (su último curriculum vitae, su archivo laboral personal y su obra escrita publicada). La trayectoria intelectual de este pedagogo se desarrolló en instituciones donde diversas tradiciones epistemológicas se disputaron el estatuto disciplinar de la Pedagogía. Uno de esos lugares fue la Universidad Nacional Autónoma de México, lugar donde se dedicó a trabajar la mitad de su vida y en la que aún sigue vivo su legado y sus ideas. Con una personalidad compleja, entre contradicciones y convicciones personales, su aprecio por la cultura en lengua castellana, fue un destacado docente, investigador y difusor de la cultura pedagógica clásica y moderna que espera ser conocido, leído y estudiado más allá del país donde siempre vivió y falleció.

Authors: Zumárraga Espinosa Marcos Rafael , Cevallos Pozo Gabriela
Published: January 2021

Esta investigación instrumental tiene el objetivo de examinar las propiedades psicométricas de la Escala de Procrastinación Académica (EPA) y la Escala de Resiliencia Académica (ARS-30) en el contexto universitario ecuatoriano. Para ello se empleó una muestra de 788 estudiantes pertenecientes a universidades públicas y privadas del Distrito Metropolitano de Quito (DMQ). La recolección de los datos empleados en el estudio se realizó mediante cuestionarios escritos y auto-administrados. Para la evaluación de cada escala se compararon modelos de medición alternativos mediante el Análisis Factorial Confirmatorio. En cuanto a la EPA, se verifica que el mejor ajuste a los datos se alcanza a partir de una estructura bifactorial y el uso de una versión reducida del instrumento a 12 ítems (χ²(53) = 234.61 [p < .001]; GFI = .953; AGFI = .931; IFI = .930; CFI = .930; RMSEA = .066). Por otra parte, la ARS-30 exhibe una estructura trifactorial, con mayor calidad psicométrica de medición al emplearse una versión recortada a 24 ítems con re-especificación (χ²(247) = 951.98 [p < .001]; GFI = .904; AGFI = .884; IFI = .904; CFI = .903; RMSEA = .060). Asimismo, las escalas ajustadas muestran resultados satisfactorios en términos de consistencia interna y validez nomológica. Se concluye que los instrumentos analizados, junto con las adaptaciones propuestas, cuentan con niveles aceptables de validez y confiabilidad para la medición/evaluación de la procrastinación y la resiliencia académica en el estudiantado universitario de Ecuador.
Aprendizaje Basado en Proyectos en la escuela secundaria argentina: un estudio exploratorio sobre la experiencia de profesoras y profesores en servicio
Authors: Corica Ana Rosa
Published: January 2021

En los últimos años, en Argentina se propuso un cambio de la educación secundaria fundamentado en el enfoque del Aprendizaje Basado en Proyectos. Este trabajo tiene como objetivo conocer las condiciones y restricciones que manifiestan experimentar profesoras y profesores en servicio, al gestionar una enseñanza por Aprendizaje Basado en Proyectos en escuelas de educación secundaria en Argentina. En este trabajo se propone una investigación cualitativa de tipo exploratoria. Se desarrolló una entrevista grupal en profundidad con profesoras en ejercicio que desarrollan funciones docentes en una escuela secundaria que promueve el Aprendizaje Basado en Proyectos. Las profesoras participaron de la gestión de un proyecto sobre alimentación saludable, en el que intervinieron la totalidad de las y los docentes del año escolar en el que se desarrolló. El análisis de la entrevista se realizó a partir del análisis de categorías de carácter deductivo. Los principales resultados indican que la especialización en que son formadas las y los profesores de la escuela secundaria, basada en la parcialización del saber, y la estructura actual de la escuela secundaria condiciona y restringe el estudio interdisciplinario que requiere emprender cualquier proyecto del mundo real. Es preciso idear propuestas compatibles con una enseñanza por Aprendizaje Basado en Proyectos para la formación de profesores que conduzcan a cambiar la propia mirada sobre su profesión y las personas estudiantes. Esto conduce a una formación que no se puede fundamentar en la reproducción o almacenamiento de información, sino que busca su funcionalidad y reconstrucción en diversas situaciones.
Construcción de un mínimo fraseológico locucional: desde el nivel A hasta el nivel C de español
Authors: Valero Fernández María Pilar
Published: January 2021

La enseñanza del español como lengua extranjera (ELE) se enfrenta todavía a diversos enigmas sin resolver. Uno de ellos versa sobre la falta de precisión en la enseñanza de la fraseología, pues en el momento actual se desconoce qué unidades fraseológicas (aquí reducidas a las locuciones) se han de abarcar en el aprendizaje en función del nivel del estudiante; al igual que no existe una instrucción concisa referente al subtipo de locución que tiene que estar presente en cada nivel lingüístico. Por ello, el objetivo del presente artículo es mostrar qué criterios se han seguido para el diseño de un mínimo fraseológico locucional ad hoc así como las unidades fraseológicas (locuciones) que lo integran para los distintos niveles comunes de referencia del MCER. Como resultado, se obtienen 39 locuciones para el nivel A1-A2, 407 para el nivel B1-B2 y 843 para el nivel C1-C2.
Modelación predictiva de siniestros en seguros de no vida
Authors: Sandí-Corrales Ana Rosa
Published: January 2021

Se analizó un seguro de accidentes y salud que tiene primas diferenciadas para grupos de riesgo homogéneos. La estimación de dichas primas en ocasiones anteriores fue de tipo univariado, que tiene la limitante de que cuando hay grupos de riesgo con pocas observaciones los resultados son muy volátiles y omiten la información que podrían aportar variables predictoras. Por lo que se optó por estimar los siniestros esperados (que son insumo del cálculo de primas) con tres modelos multivariados: lineales ordinarios, aditivos y lineales mixtos. Se utilizaron varios con el fin de comparar su capacidad de pronóstico. El desempeño fue aceptable tanto dentro de la muestra de ajuste como de prueba en el caso de los modelos lineal ordinario y aditivo con una diferencia porcentual de alrededor del 1% con respecto a los datos reales. El lineal mixto no pudo hacer pronósticos para combinaciones de predictores no observados en los datos de ajuste.

METHODS: In this research, it has used two quantitative approaches as the Self-Organizing Maps and the Partial Least Square Structural Equation Model (PLS-SEM) over two different years such as 2007 and 2017 in a sample of farms belonging to the Farm Accountancy Data Network dataset.
RESULTS: Findings have emphasized the impact and the main role of financial subsidies in stimulating rural growth even if there are also lots of unbalances between EU states.
CONCLUSIONS: The role of the public administrations at a local level should be addressed towards a strictly severe task to condense main priorities of rural development and the needs of the rural population in specific and pilot initiatives.
Labour productivity of dairy cattle farming in Central and Southeast Bulgaria
Authors: Stankov K.
Published: January 2021

A study was conducted on labour productivity in dairy cattle farms that breed Black-and-White cows. The study encompassed 90 farms, thus including 6471 cows. The farms were divided into four groups: small – 8 farms with an average of 3.6 cows; medium – 32 farms with an average of 22.9 cows; large – 32 farms with an average of 74.2 cows; and huge – 18 farms with 185.3 cows per farms.
The results of the study indicated that large and huge farms are distinguished by high labour productivity. The income from production, profit, milk quantities, and the cost of one annual work unit (AWU) and a man-hour were several times higher compared to small and medium farms. Production was organised at a much better technological level, which was a contributing factor towards high-quality and competitive milk production. A recommendation to the small and medium farms would be to grow larger, improve their selection, and develop technologically.

Powołanie kobiety do macierzyństwa i mężczyzny do ojcostwa w kontekście dyskursu katolicyzmu z ideologią gender w polskiej literaturze przedmiotu
Authors: Krępa Magdalen
Published: January 2021

Publikacja koncentruje się na ważnym aspekcie procesu społeczno-kulturowych przemian, a mianowicie na relacji kobieta-mężczyzna w kontekście rodzicielstwa i funkcjonowania rodziny. Istota problemu polega na tym, że w miejsce komplementarności płci, czyli idei uzupełniania i obdarowywania się swoją różnorodnością, ideologia gender proponuje całkowitą dekonstrukcję i redefinicję płciowości odrywając ją od naturalnych (biologicznych) korzeni i przenosząc jej sens w sferę kultury. Z takim stanowiskiem Autorka zamierza polemizować. Swoje analizy opiera na materiałach z obszaru kilku dyscyplin naukowych (teologia, filozofia, socjologia, ale także biologia i psychologia), sięga do licznych dokumentów Kościoła, ogranicza się do źródeł publikowanych w języku polskim.
Negatywne konsekwencje braku poszanowania godności pracownika medialnego
Authors: Teler Anna
Published: January 2021

Negatywne konsekwencje braku poszanowania godności pracownika medialnego. Godność osoby w mediach często bywa rozpatrywana w kategoriach relacji nadawcy z odbiorcą lub w kontekście przestrzeni wolności, prawdy i innych wartości na poziomie przekazu i zawartości medialnej. Jednak równie ważną perspektywą są relacje wewnątrz przedsiębiorstwa, za kulisami widowiska medialnego. Czy można bowiem uznać media za godne osoby, jeśli pominięty lub zmarginalizowany jest aspekt pracowniczy? Branża medialna uznawana jest za trudną i wymagającą, osadzoną w realiach dwojakiej konkurencji intramedialnej i intermedialnej oraz konkurencji niedoskonałej – przy jednoczesnych wysokich wymaganiach dotyczących jakości, w szybko zmieniającym się otoczeniu biznesowym, uznawanym za turbulentne i wrogie. Wpływanie na społeczeństwo, (współ)kreowanie opinii publicznej, inicjowanie zmiany zachowań, balansowanie po cienkiej linii obiektywizmu i tendencyjności (zwłaszcza w kontekście sympatii politycznych) – to codzienność medialna. Idealne media zdają się nie istnieć. Być może, dlatego właśnie niezwykle ważne jest poczucie odpowiedzialności i etyczna orientacja na stanowiskach kierowniczych. Działania zarządcze zorientowane etyczne zaczynają się od uznania godności pracownika, co pozwala przezwyciężać patologie organizacyjne. Prezentowany artykuł to przegląd stanowisk i wiedzy teoretycznej ukazujący stan aktualny oraz propozycja przezwyciężania negatywnych tendencji, zwłaszcza patologii organizacyjnych, obecnych w branży medialnej, na gruncie poszanowania godności pracownika medialnego.

One of the most important stages of the high-purity chalcogenide glasses’ analytical control is the determination of matrix elements’ content with the uncertainty at the levels of 0.1–0.2 mol.%. The content of the macro-components may differ from the composition of the initial charge; therefore, an important task is the macro-composition determination of the final materials. This article describes the development of the technique for determining the matrix elements of high-purity Ge-Se-Te glasses in the range of germanium content from 10 to 35 mol. %, selenium and tellurium content from 20 to 50 mol. % with the expanded uncertainty within 0.01–0.2 mol. % (P = 0.95) using the inductively coupled plasma atomic emission spectrometry (ICP-AES). A simple technique for the preparation of primary calibration solutions from pure elementary Ge, Se and Te is proposed. The correctness of the analysis results is confirmed by comparing the calculated matrix composition of model glass samples, prepared by direct synthesis from high-purity simple substances in the sealed quartz glass ampoule, with the analysis results. The main advantage of the proposed analysis technique is the absence of the need for the reference samples identical to the analyzed material, which is especially important for determination of new materials’ matrix composition. The minimum sample mass for the determination of matrix elements is about 1 mg, which makes it possible to analyze not only bulk glass samples, but also fibers and expensive materials.
UHPLC-HRMS determination of adrenaline and dopamine dansyl derivatives in human saliva
Authors:   Kuban State University, Azaryan A. A. , Dmitrieva E. V. ,   Kuban State University, Temerdashev A. Z. ,   Kuban State University
Published: January 2021

In the last decade, the quantification of catecholamines in human biological fluids has been of great interest. Changes in catecholamine levels, such as adrenaline and dopamine, in the body lead to neurological disorders as well as several diseases, namely Alzheimer’s and Parkinson’s diseases, neuroendocrine catecholamine - producing tumors - pheochromocytoma, paraganglioma, carcinoid tumors and neuroblastoma. Moreover, different drug combinations can lead to the distortions in the human biological passport, containing the information not only about the erythropoiesis and steroid profile, but also about catecholamine levels, which are difficult to quantify in terms of sample preparation and analysis. A method has been proposed for the determination of adrenaline and dopamine dansyl derivatives in human saliva, including the derivatization and determination of analytes by ultra-high-performance liquid chromatography (UHPLC) with high resolution mass spectrometric detection. The derivatization procedure allowed obtaining less polar catecholamine derivatives, which is especially important for their quantification by reversed-phase ultra-high-performance liquid chromatography since it ensures their better retention on the sorbent. The sensitivity of these substances quantification by the proposed method was estimated; the highest sensitivity was achieved using the mobile phase consisting of the 0.1% formic acid aqueous solution and acetonitrile. The lower limit of quantification was 5 ng/mL for dansyldrenaline and 10 ng/mL for dansyldopamine respectively. The proposed technique was tested on real saliva samples obtained from volunteers to quantify catecholamine dansyl derivatives by reversed-phase high-performance liquid chromatography with high-resolution mass spectrometric detection. High sensitivity of the technique allows using it for adrenaline and dopamine determination in clinical diagnosis.

Comparison of the effect of general and spinal anesthesia for elective cesarean section on maternal and fetal outcomes: a retrospective cohort study
Authors: Sung Tae-Yun , Jee Young Seok , You Hwang-Ju , Cho Choon-Kyu
Published: January 2021

Background: Anesthesia is needed to ensure both maternal and fetal safety during cesarean sections. This retrospective cohort study compared maternal and fetal outcomes between general and spinal anesthesia for cesarean section based on perioperative hemodynamic parameters (pre- and postoperative systolic blood pressure, heart rate), mean difference of hematocrit and estimated blood loss, and neonatal Apgar scores at 1 and 5 min.Methods: Data from electronic medical records of 331 singleton pregnancies between January 2016 and December 2018 were analyzed retrospectively; 44 cases were excluded, and 287 cases were assigned to the general group (n = 141) or spinal group (n = 146).Results: Postoperative hemodynamic parameters were significantly higher in the general group than the spinal group (systolic blood pressure: 136.8 ± 16.7 vs. 119.3 ± 12.7 mmHg, heart rate: 93.2 ± 16.8 vs. 71.0 ± 12.7 beats/min, respectively, P < 0.001). The mean difference between the pre- and postoperative hematocrit was also significantly greater in the general than spinal group (4.8 ± 3.4% vs. 2.3 ± 3.9%, respectively, P < 0.001). The estimated blood loss was significantly lower in the spinal than general group (819.9 ± 81.9 vs. 856.7 ± 117.9 ml, P < 0.001). There was a significantly larger proportion of newborns with 5-min Apgar scores < 7 in the general than spinal group (6/141 [4.3%] vs. 0/146 [0%], respectively, P = 0.012). Conclusions: General group is associated with more maternal blood loss and a larger proportion of newborns with 5-min Apgar scores < 7 than spinal group during cesarean sections.

The sphere of scientific interests of Doctor habil. in Law, Professor V.S. Ishigeyev is a reflection of multiversity and remarkability of his personality and is determined both by the previous and currently implemented experience of practical law enforcement activity. Criminal behavior countermeasure as an aggregate of multi-aspect measures of criminal and criminological, in particular, policy is regarded by him through the measures of penitentiary prevention, criminalistics and criminal-legal support of their efficiency. Establishment of the professors scientific sphere was connected with criminalistic works and thesis research which became a deflection of his successful work in the interior affairs bodies and his academic activity in the Chair of Criminal and Legal Disciplines of Irkutsk Branch of Khabarovsk Law Enforcement Academy (now East-Siberian Institute of Ministry of Interior Affairs of the Russian Federation). The further scientific studies were connected with problems of penitentiary criminality and measures of it prevention. The thesis research, prepared in the Chair of Criminal Law and Criminology of Baikal State University and devoted to these problems, allowed to develop understanding of the criminal-penitentiary prevention and criminal-penitentiary legislation. V.S. Ishigeyev is an active advocate of developing the teaching of professional criminality and its topical manifestations, the theory and practice of qualification of separate types of crimes and criminal punishment. Being the author of seven monographs, eight study letters, and more than 50 scientific articles of the criminal and legal cycle, Professor Ishigeyev is successfully lending his knowledge and experience, including his practical activities, to his followers, 16 Ph.D. theses were defended under his scientific supervision.

Cyber-Victimology as a New Reality of the Technotronic Society (Gender Research)
Authors: Zhmurov Dmitry , Klyuchko Rimma
Published: January 2021

The article studies some issues of cyber-victimology development. This is a doctrine of the crime victim committed with the help of computer technology. The purpose of the study is to identify the real situation of еру cases regarding the victimization of different sexes on the Internet (in the regional aspect). For this purpose, a poll of 584 students of all major universities of Irkutsk Oblast was conduсted. The respondents were asked to assess the dangers of using the Internet and indicate instances of individual victimization in this environment. To obtain information on gender differences of cyber-victimization, the respondents were divided in term of genders (221 men and 363 women). The study showed that, like in ordinary life, in the virtual space, men more often demonstrate risky behavior, neglect of safety rules and frivolous attitude to possible threats. Victims on the Internet are often those who have already been a victim in real life. At the same time, women are more often exposed to victimization effects (there are almost four ypes of discriminatory acts per one female user, while there are three acts per a man on the average). Types of victimization effects are also gender-specific. The largest discrepancy in the structure of victimization was recorded for hacking into an account on social networks (6 % for men against 49 % for women); installation of malicious programs on the computer (14 % against 8 %); insults (20 % against 10 %) and indecent proposals (10 % against 25 %), as well as embezzlement of confidential information (3 % against 1 %). Thus, men are more likely to become victims of the theft of passport data (payment cards), are subjected to attacks by extortionists, verbal aggression, or suffer from dishonest sellers of goods. Women with a higher frequency become victims of hacking into accounts in social networks and sexually colored cyber-stalking. Significant damage, despite a small number of such cases, was almost twice as often caused to men. The results of the study indicate that more than 90 % of the surveyed age group were victims of cybercrimes, as a rule, of several ones. According to the respondents reports, about 15 various forms of victimization effects on the Internet were identified. Among them there is hacking of a mailbox or an account, dissemination of false information on behalf of the users name, indecent offers, sexual harassment, registration of paid Internet subscriptions, false repayment of the fine, and so on.

In the modern world, distance employment is becoming more widespread due to socioeconomic reasons. The researchers have covered in detail the issues related to the advantages and disadvantages of remote work for both employers and employees, studied the scale and causes of the spread of this phenomenon in the Russian labor market as well. To a lesser extent, the issues directly related to the organization of employees' labor and management features due to both the nature of labor and the distinctive features of employees who choose this type of employment are considered. At the same time, switching to remote work requires making informed decisions. The authors' fundamental point is that not only the interests of the business but also the opinion of the staff should be taken into account when making a decision to switch to remote work. This approach will allow researchers to obtain better results due to a more accurate forecast of possible problems and a well-designed system of organizational support for the transition.

Struggles for African independent education and land rights on the Rand and the significance of the Tsewu court case, 1903-1905: A new analysis
Authors: Kumalo Vusumuzi R.
Published: January 2021

The years between 1886 and 1910 were among the most dramatic in the history of southern Africa. Scholars have documented Johannesburg's urban history and racial politics during this period. What has often been overlooked, however, and which this article draws attention to in a fresh analysis, is the connection between the colonial state's limitation of African rights to land ownership and the development of the struggle for an independent system of education for Africans. At the local level, this broader struggle was expressed explicitly in African discontent at municipal administrative failure to address the issues of adequate sanitation, land rights, tenure security, and prospects for upward mobility. This article argues that it is in a reassessment of the significance of the 1905 litigation initiated by Reverend Edward Tsewu which provides a basis for this new inquiry into the connection between the African struggle for property rights and independent education.
Programmes of frivolity on ice? Hockey, business, diasporic identity and apartheid in South Africa, 1936-1992
Authors: Snyders Hendrik
Published: January 2021

South Africa has a surprisingly long history of the sport perhaps most usually associated with the northern hemisphere: ice hockey. Ice skating was first introduced in the country in the last decade of the nineteenth century as a commercial venture. Entrepreneurs built ice rinks for profit-making purposes and brought showmen from overseas to demonstrate the sport. An ancillary activity was the establishment of ice hockey clubs in 1936 and beyond. Given the strong profit motive, personal and tactical differences between the chief investors and sports administrators inevitably left its imprint on the sport. The extensive involvement of German, Canadian and Swiss immigrants throughout the twentieth century also co-determined the eventual character of the sport. From its inception through to 1991, ice hockey practised racial segregation, operated within apartheid laws and remained an exclusively white activity. Unsurprisingly, the apartheid ice rink also became embroiled in global politics, became a target of the worldwide anti-apartheid sports boycott and was excluded from all international competition from the late 1960s until 1991. This article reclaims some of ice hockey's neglected history in South Africa and investigates the interplay of sport, ice rink entrepreneurship, imperial and foreign identity, and apartheid politics during the twentieth century.

Investigating Turkish Pre-service Science Teachers’ Moral Reasoning in Genetics related Socioscientific Issues
Authors: Cebesoy Ümran Betül
Published: January 2021

In this study, Turkish pre-service science teachers' moral reasoning patterns and the factors which influence their decisions while discussing genetics-related socio-scientific issues (SSI) were investigated. A basic qualitative approach was adopted for this purpose. Seven third-grade pre-service science teachers enrolled in the study. Semi-structured interviews for different genetics related SSI were conducted. The results revealed that decisions were generally based on the consequences of genetic applications (consequentialist) or based on moral principles or prescripts (principle-based). Most participants used consequence-based moral reasoning in their decisions, while principle-based moral reasoning was less used. They also used emotion-based moral reasoning.  Their decisions were influenced by emotions, including empathy or sympathy toward the characters, or the unborn baby, in the scenarios. Additional and varied factors, including legal, ethical, economic, and technological concerns, were revealed as influential. Participants' decisions were also shaped by their own experiences, media resources, and faith in science. The implications for science teacher education programs are discussed.

Authors: YÜCEL Gül
Published: January 2021

Cerebrovascular complications occur in 25%–70% of patients with infective endocarditis (IE). Among these complications, ischemic stroke, intracerebral hemorrhage and cerebral abscess are frequently seen and usually the consequence of vegetation embolization or ruptured infectious (mycotic) aneurysm. Acute subdural hematoma (ASDH) is a very rare complication of IE due to multiple septic brain embolisms. Presented herein was a 15-year-old child with a very rare presentation of ASDH, which resulted from ruptured mycotic aneurysm. To the best of our knowledge, only 13 cases have been reported in the literature with an ASDH due to IE. The reported case herein was the second child case with mycotic aneurysms- related ASDH and intracerebral hemorrhage. Also discussed were the pathogenesis, clinical manifestation, and management of this rare neurologic complication of IE in the current knowledge. The aim of this study was to analyze the clinical features and management of subdural hematoma in pediatric patients with infective endocarditis in light of the literature.

Authors: Piechota Grażyna
Published: January 2021

This article analyses the role of social media as a transnational discursive space and the impact of networked communication on the formation of the traditional mass media agenda regarding political protests that began in June 2019 in Hong Kong. The aim of the present research was to indicate the degree of impact of the dominant themes in networked communication during the anti-extradition bill protests in the transnational network discourse and the impact on the news media agenda, taking into account the activity of user-generated network traffic around the published content. The research was based on two theories shaping the perception of political protests in an international context - theory on transnational discursive spaces and theories of agenda setting. The research was carried out using quantitative content analysis and confirmed that global social networking sites Facebook and Twitter are important channels in creating transnational discursive spaces that affect the news media's agenda. Findings show that social media plays an important role in organizing political protests, and is a tool for establishing transnational discursive spaces; despite the fact that the protesters used applications protecting their data for communication, with the assistance of information and integrated collaboration by other entities. The results obtained contribute to the research on media studies which highlight the role and importance of social media in the process of communicating about political protests.
