ἔργα Λήμνια: the mythological original and its copy?
Authors: Gouschin Valerij
Published: September 2021

"Lemnian Deeds" is a well-known literary and mythological topic. It includes two events: 1) the murder of the husbands and all the men of the island by the Lemnian women; 2) the killing of the Athenian women and their children by the Pelasgians. Researchers have long noticed the affinity of these events. Some scholars believe that the narration of the crime of the Pelasgians was created according to its Lemnian prototype. Or, to put in other way, one of the events became a kind of copy for the other. This paper provides a different interpretation to the noted similarity.
Theology in the context of the dramatic nature of Plato's dialogues
Authors: Svetlov Roman
Published: September 2021

The so-called «dramatic approach» to the interpretation of Plato's texts provides us with some additional tools to explore his theological concepts. The article examines possible ways to connect with each other two "theologies" that are found in Plato's dialogues: static theology from the intelligible universe, and dynamic theology from the visible universe, which is in constant genesis. From the point of view of the «dramatic» approach, we must constantly keep in mind the various assessments of the problems posed by Plato's Socrates and other characters in the dialogues in order to have a complete picture of the analyzed matter. To reconcile these two "theologies", the description of the ambivalent nature of the human soul in «Lysis» plays a basic role, which is also confirmed in other Platonic texts.
Ancient mythological scenes on the artifacts from China
Authors: Shulga Daniil
Published: September 2021

The topic of Chinese material culture is quite rare in modern classical studies. However, even the analysis of a few artifacts found in the territory of China allows us to enrich significantly our understanding of the occurrence of Hellenic mythological motifs outside their "traditional area" (both geographical and chronological). On the territory of the Greco-Roman Mediterranean, already in the first centuries of our era there is a gradual strengthening of new religious-philosophical doctrines, but on the Great Silk Road we can state a kind of "conservation" of mythological images dating back to the archaic period of Greece (or even to the Mycenaean era). We are not talking about unfounded interpretations, but about artifacts with many details characteristic of the Greco-Romanic world. Such images are little known in Russian-speaking scholarship, therefore it is relevant for the study of Greco-Asian syncretism to make them available for classicsts.
The true date of Meton’s observation of the summer solstice
Authors: Panchenko Dmitri
Published: September 2021

The date assigned to Meton’s highly reputed observation of the summer solstice in the Almagest implies June 27, 432 BC. Since the solstice took actually place a day later, such an inaccuracy presents a puzzle. It can be demonstrated, however, that Meton’s observation was in fact accurate, for he made it on June 28, 433 BC. This follows from adequate interpretation of chronological indications in Thucydides and finds support in various data of the ancient sources. The mistaken date arose, and was maintained, because of the misleading assumption according to which the Athenian archon year invariably began after the summer solstice. It was wrongly decided that Meton had observed the summer solstice at the end of the year of the archon Apseudes and not at its initial part. The true date of Meton’s solstice presents in new light the observation of the summer solstice by Aristarchus of Samos, Eudoxus’ preoccupation with the octaeteris and early Greek astronomy in general. The beginning of the Peloponnesian War is now firmly established at early April (almost certainly, April 6), 431 BC.

Cystic fibrosis (CF) is a severe life-limiting genetic disorder resulting from mutations in the cystic fibrosis transmembrane regulator gene and is reported to be more prevalent among Caucasians than people of African descent. The past three decades have seen a gradual increase in the reporting of CF in non-European populations with CF in all regions including Africa. We report on the first two known Ghanaian children diagnosed with CF presenting early in infancy. The first patient presented with severe acute malnutrition and persistent diarrhea resulting from severe exocrine pancreatic insufficiency. In the second patient, there were recurrent wheeze and recurrent pneumonia, severe dehydration with metabolic alkalosis. Diagnosis of CF in Ghana is challenging due to the absence of diagnostic tools such as sweat testing equipment. In the first patient, sweat testing and genetic testing were done in South Africa. In the second patient, sweat testing was not done but diagnosis was confirmed by genetic testing. Both patients presented with classical CF symptoms including Pseudomonas aeruginosa airway infection before age 6 months. Both children are currently alive and healthy on appropriate treatment. These case reports highlight the growing evidence of CF occurring in people of African descent and the diagnostic challenges faced in Africa.

The cultivation of shallots in peat is constrained by the low level of soil fertility and one of methods to increase the nutrient content is by applying trichocompost. Trichokompos is material from plant residues that are composted and mixed with Trichoderma sp. as decomposers. Trichocompost improves soil fertility (soil biology, physics, and chemistry). The purpose of this study was to determine the effect of trichocompost doses on various peat compositions on the yield of shallots. Research was conducted at the Experimental farm of Faculty of Agriculture, Islamic University of , Pekanbaru during 4 months, starting form June to September 2018. The design used was completely randomized factorial with 2 factors, namely Trichocompost Dose, levels 0, 4, 8, 12 g Trichoderma/kg compost and peat composition level: 100, 75, 50, 25%. Parameters tested: plant height, age of tuber formation, number of leaves, number of tubers, and tuber weight. The data were statistically analyzed and the BNJ follow-up test at 5% level. The results showed that the dose of trichocompost combined on peat had a significant effect on all observation parameters and the best treatment was 8-12 g trichoderma/kg compost at 75% peat composition.

Application of synthetic chemical insectices is known to be the most effective approach in addressing infestation of insect pests. However, conventional insecticides are not appropriate to be applied against pests of stored food materials, such as peanut due to the residue issue. Method of fumigation which negate the residue issue is also not feasible for public practice due to the hazard potency. This consideration necessitates the exploration of safe insecticide material such as neem leaf and piper leaf using suitable method. Paper presented here is a literature review design to analyze related to the important pest of stored peanut, content and effication of neem and piper leaves, and the efficiency of muslin-cloth pad containing the botanicals. Based on the neem characteristics which is anteefedant and the characteristics of piper leaf which is volatile. It can be concluded that botanicals from these two species prepared in muslin-cloth pad, would be able to control pest of stored peanut.

Authors: García Romero Enrique , Huamán Flores Fernando , Palomino Moreno Henry Wilfredo
Published: September 2021

Este artículo muestra los resultados de una investigación académica sobre el modo en que la prensa peruana aborda el tema del aborto. Se ha realizado un análisis de contenido para detectar los encuadres, los temas y las fuentes periodísticas presentes en 160 textos publicados en el quinquenio 2015-2019 por los diarios El Comercio, Perú 21, La República, La Hora, Correo y El Tiempo. Los tres primeros forman parte de la prensa más leída en la región de Lima metropolitana, mientras que los tres últimos están entre los diarios más leídos en la región de Piura. Estas dos regiones son las más pobladas del país andino. Una de las variables del análisis de contenido son los encuadres genéricos utilizados por la prensa: provida, proaborto y neutro/ambiguo. Los resultados muestran que cinco de los seis diarios seleccionados –todos excepto El Comercio– utilizaron mayoritariamente encuadres provida, es decir, opuestos al aborto inducido. Por otra parte, los tres diarios que forman parte de la prensa más leída en la región de Piura utilizaron porcentualmente encuadres más provida que los tres diarios que forman parte de la prensa más leída en la región de Lima metropolitana. En cuanto al tipo de fuentes a las que recurrieron los periodistas para informar sobre el aborto, pertenecen mayoritariamente a los ámbitos político y religioso, mientras que las del ámbito científico quedaron relegadas a un tercer lugar.

Los estudios sobre los estereotipos de género se han enfocado en la publicidad tanto comercial como política, en especial en las campañas electorales donde se sugiere que estas percepciones surgen del medio social y permanecen como un reflejo de cultura e historia preservando normas sociales. El presente estudio busca, mediante un análisis de contenido cuantitativo, identificar los estereotipos de género utilizados en los spots políticos emitidos durante las campañas de diversos procesos electorales mexicanos de 2018, su proyección y diferencias de acuerdo con el género de la persona que aparecía como candidata o candidato. La investigación indica que los estereotipos más utilizados son los más favorables respecto de las mujeres (moderna y luchadora-transgresora) aunque los que tuvieron una mayor exposición en medios fueron los referentes a mujer sensual y mujer frágil o sometida. Los estereotipos positivos tuvieron mayor presencia en la publicidad de las candidatas, mientras que los negativos se encontraron más veces en los spots genéricos normalmente elaborados por los propios partidos.
Gender (in)equality in Chilean press: journalists and sources

Published: September 2021

Who writes the news in the Chilean press according to gender? Who are the sources, male or female, in the Chilean press? Is there a relationship between the gender of journalists and the gender of the sources in the Chilean press? This article studies the gender of the Chilean newsroom and their sources in 12,113 news through a quantitative method with a computational social science approach. This method combines web scraping and natural language processing techniques to gather and preprocess data, facilitating the exploration of complex social phenomena. Results show important biases in journalists and source gender. From a sample of 158 journalists, 99 were men (63%) and 59 women (37%). Also, from 12,113 news, 7,565 (62%) were written by male and 4,548 (38%) by female journalists. Of the 12,334 sources mentioned in the news, 9,771 were men (79%) and 2,563 were women (21%). A significant finding is that equality in the newsroom is related to how female and male journalists choose their sources. In other words, when a media has a newsroom with gender equality, the sources of the journalists are more equitable too. These results have important insights to discuss within the journalism schools, to make students aware of the gender bias in the profession. Furthermore, if the presence of female – journalists or sources- increased in the media, it would allow them to grow their media power and status.

Authors: Meso Ayerdi Koldobika , Pérez Dasilva Jesús Ángel , Mendiguren Galdospin Terese
Published: September 2021

La aparición de las redes sociales ha proporcionado a los futbolistas un medio novedoso y muy eficaz para llegar a sus seguidores e interactuar con ellos. Este nuevo giro en las relaciones entre jugadores y aficionados ha suscitado un reciente debate (Cleland, 2009) sobre los intentos de estos deportistas de conectarse con el público y potenciar sus imágenes de marca a través de Twitter (Hutchins, 2011). La presente investigación pretende analizar los aspectos del comportamiento en Twitter de los cinco futbolistas que compiten en las principales ligas europeas con mayor número de seguidores en la red de microblogging. Se trata de ver cómo se relacionan estos deportistas con sus aficionados, con quienes hablan y de qué hablan, con el fin de determinar la forma en que estas personas utilizan Twitter para crear marcas personales y forjar conexiones entre ellos y los clubes para los que juegan y los aficionados. El análisis de contenido se utilizó para detectar los patrones de difusión de los mensajes e identificar a los principales protagonistas de las conversaciones examinadas. También se analizaron las redes semánticas y el uso de hashtag para encontrar correlaciones significativas entre las palabras. Para esta parte del análisis se utilizó NodeXL, programa de software de código abierto más utilizado en el análisis de redes sociales (Hansen, Shneiderman & Smith, 2010). Uno de los principales usos que hacen de Twitter está vinculado a la autopromoción. Además, los perfiles de estos futbolistas suelen apoyar iniciativas y campañas solidarias.
Evolución del informativo audiovisual en opinión de sus creadores: de la televisión a la carta al vodcasting
Authors: Moreno-Espinosa Pastora , Román-San Miguel Aránzazu , Flores-Vivar Jesús Miguel
Published: September 2021

Si hasta ahora los informativos habían sido pensados para su difusión a través de grandes formatos de pantalla, sobre todo pantallas de televisión y ordenador, desde hace una década, los programadores se han esforzado por llegar a los consumidores de formatos más reducidos de receptores como las tabletas y, más recientemente, los teléfonos móviles. Ante dicha realidad, los informativos en televisión se han ido redefiniendo y reorientando, utilizando incluso imágenes no profesionales para su difusión. En este artículo, se hace un repaso de la evolución del informativo audiovisual, del informativo en televisión a la televisión a la carta y de ahí, su paso al vodcasting; todo ello a través de una bibliografía actualizada y la visión de los directivos de informativos en televisión. Hacemos uso, por tanto, de una metodología cualitativa, descriptiva y exploratoria aplicando como herramienta metodológica el cuestionario. La información audiovisual ha sido siempre la más consumida y se ha incrementado con situaciones como la pandemia mundial de la enfermedad COVID-19. Según el informe de la consultora Barlovento Comunicación publicado en junio de 2020, el consumo audiovisual en España creció un 22%, tanto a través de la televisión convencional como de Internet. La gestión de la sobreinformación y su adaptación a los nuevos entornos de consumo debe ser una máxima para los gestores de contenidos periodísticos. Nuestro estudio concluye, entre otras cosas, que aunque las formas de consumo han variado considerablemente y los directivos de informativos en televisión creen que éstos deben adaptarse a ellas, hasta el momento se han adaptado contenidos a esos nuevos formatos, pero se produce poco material expresamente para las plataformas de podcasting de vídeo o vodcasting en nuestro país.

Published: September 2021

Este artículo analiza el proceso de mediatización cultural de las celebridades tomando como caso de estudio la auto-presentación en la red social Instagram de la cantante Rosalía (@rosalia.vt). Para ello se ha realizado un doble análisis cuantitativo y cualitativo de las 449 publicaciones que la cantante realiza entre el 1-1-2018 y el 31-7-2020, periodo en que alcanza fama internacional con el lanzamiento del álbum El Mal Querer. El análisis estadístico descriptivo de esta muestra permite determinar los patrones de publicación de la cantante, las categorías a las que asocia su imagen y el uso que hace de las potencialidades de esta red social. El análisis iconológico de la muestra permite determinar los referentes culturales que Rosalía asocia a su imagen, dentro de un contexto globalizado, urbano y de inspiración flamenca. Este estudio concluye que Rosalía aparece como un caso tipo de “celebritización”, ya que usa estratégicamente la lógica mediática de las redes sociales como una manera de afianzar su marca personal diversificándola más allá del ámbito de la música.
Repatriación en pandemia de covid-19. Encuadres de la prensa latinoamericana
Authors: Gaete Quezada Ricardo
Published: September 2021

El estudio analiza la cobertura informativa de ocho periódicos latinoamericanos sobre la crisis migratoria acontecida el año 2020 como consecuencia de la pandemia de Covid-19, que obligó a miles de migrantes a retornar forzadamente a sus países de origen, enfrentados al cierre de fronteras terrestres, marítimas y aéreas, problemática agudizada además por la pérdida de sus puestos de trabajo en los países receptores. Se desarrolla un análisis de contenido cualitativo relacionado con los encuadres informativos presentes en las noticias digitales publicadas durante los seis primeros meses desde que se declaró la pandemia a nivel global, observándose que los encuadres de atribución de responsabilidad y conflicto concentran el foco noticioso en las informaciones publicadas por los medios de comunicación incluidos en la muestra, concluyéndose que los encuadres periodísticos sobre la repatriación durante la pandemia concentraron la cobertura informativa en las acciones de los gobiernos de la Región, especialmente de los Ministerios de Relaciones Exteriores y las misiones diplomáticas de los países latinoamericanos como principales autoridades gubernamentales responsables de la repatriación, así como respecto de las informaciones relacionadas con las tensiones políticas surgidas a nivel internacional entre algunos estados latinoamericanos, respecto de la gestión del retorno de las personas que quedaron varadas en el extranjero sin poder ingresar a territorio nacional, debido a las restricciones al ingreso y libre circulación de personas impuesta por los gobiernos de la región.
El reportaje de infoentretenimiento: evolución del género en las televisiones generalistas en España (1990-2020)
Authors: García-Avilés José Alberto
Published: September 2021

El macrogénero del infoentretenimiento televisivo comprende diversos géneros y, con independencia de la etiqueta con la que se defina cada uno, ofrece un amplio abanico de variaciones y combinaciones que se reinventa constantemente. El reportaje de infoentretenimiento implica una mutación del género puramente informativo, ya que la representación de las vidas cotidianas se ha convertido en un gran espectáculo televisivo con rasgos propios. Esta investigación identifica 29 programas de reportajes de infoentretenimiento emitidos en la televisión generalista en España entre 1990 y 2020 y estudia su evolución. Los canales que han emitido un mayor número de reportajes de infoentretenimiento son La Sexta (once programas) y Cuatro (ocho), seguidos por La 1de TVE (cuatro), Antena 3 (tres) y Telecinco (tres). Los resultados muestran que los reportajes de infoentretenimiento, producidos en su mayoría por productoras externas a las cadenas, presentan una estética con estilo documental, abordan historias de la gente ordinaria, conceden protagonismo al reportero, apelan a la emoción y potencian la hibridación del género.
Admissible Inference Rules and Semantic Property of Modal Logics
Authors:   Siberian Federal University, Rimatskiy V.V.
Published: September 2021

Firstly semantic property of nonstandart logics were described by formulas which are peculiar to studied a models in general, and do not take to consideration a variable conditions and a changing assumptions. Evidently the notion of inference rule generalizes the notion of formulas and brings us more flexibility and more expressive power to model human reasoning and computing. In 2000-2010 a few results on describing of explicit bases for admissible inference rules for nonstandard logics (S4, K4, H etc.) appeared. The key property of these logics was weak co-cover property. Beside the improvement of deductive power in logic, an admissible rule are able to describe some semantic property of given logic. We describe a semantic property of modal logics in term of admissibility of given set of inference rules. We prove that modal logic over logic 𝐺𝐿 enjoys weak co-cover property iff all given rules are admissible for logic.

Layer-finite groups first appeared in the work by S. N. Chernikov (1945). Almost layer-finite groups are extensions of layer-finite groups by finite groups. The class of almost layer-finite groups is wider than the class of layer-finite groups; it includes all Chernikov groups, while it is easy to give examples of Chernikov groups that are not layer-finite. The author develops the direction of characterizing well-known and well-studied classes of groups in other classes of groups with some additional (rather weak) finiteness conditions. A Shunkov group is a group 𝐺 in which for any of its finite subgroups 𝐾 in the quotient group NG(K)K any two conjugate elements of prime order generate a finite subgroup. In this paper, we prove the properties of periodic not almost layer-finite Shunkov groups with condition: the normalizer of any finite nontrivial subgroup is almost layer-finite. Earlier, these properties were proved in various articles of the author, as necessary, sometimes under some conditions, then under others (the minimality conditions for not almost layer-finite subgroups, the absence of second-order elements in the group, the presence of subgroups with certain properties in the group). At the same time, it was necessary to make remarks that this property is proved in almost the same way as in the previous work, but under different conditions. This eliminates the shortcomings in the proofs of many articles by the author, in which these properties are used without proof.

We consider a linear-quadratic optimal control problem with indefinite matrices and the interval control constraint. The problem also has a regularizationparameter in the functional. The approximate solution of the problem is carried out on subsets of admissible controls, which are formed using linear combinations of special functions with an orientation to the optimal control structure due to the maximum principle. As a result of this procedure, a finite-dimensional quadratic optimization problem with the interval constraint on variables is obtained. The following relations between the variational problem and its finite-dimensional model are established: the convexity property of the optimal control problem is preserved for finite-dimensional model; a nonconvex optimal control problem under a certain condition on the regularization parameter (estimate from below) is approximated by a convex quadratic problem, which is solved in a finite number of operations;a special non-convex optimal control problem with an upper bound on the regularization parameter passes into the problem of minimizing a concave function on a finite set of points. A special case of a non-convex optimal control problem for the maximum of the norm of the final state is distinguished. Two procedures for improving the extreme points of finite-dimensional model are constructed, which reduce the computational costs for the global solution of the problem within the framework of the linearization method.

To search for signals of the phase transition of matter from the hadronic state to the quark­gluon plasma, interactions with extreme characteristics are studied. The study of the dependence of the av­erage multiplicity on the projectile energy for sulfur and silicon nuclei with energies of 3.7 AGeV, 14 AGeV, and 200 AGeV has been carried out. Experimental data on inelastic interactions with the nuclei of the NIKFI BR­2 emulsion obtained at the SPS at CERN and at the Synchrophasotron at JINR. To take into account fluctuations in the initial conditions of the nucleus­nucleus interaction, the events were divided into central and peripheral ones. A comparative analysis of the average multiplicity with heavy and light nuclei of the photographic emulsion is presented. The multiplicity increase factor has an almost linear increase in energy (on the logarithmic axis) for all events, except for the central interactions of sulfur nuclei with heavy emulsion nuclei at 200 AGeV. These events are explosive events, which give a flux of secondary particles in a narrow range of average pseudo­rapidity and significantly shifted towards low values <η>. The analysis of events of complete destruction of the projectile nucleus is presented. Such events are considered as events in which the most favorable conditions are created for the formation of a quark­gluon plasma.
A Customisable Cell Line Model of Glioblastoma
Authors:   , Forsythe Devlin
Published: September 2021

Glioblastoma is an extremely malignant brain tumour with one of the lowest survival rates of all cancers. Current treatments do very little to alter this prognosis. Research into new therapies and the biology of glioblastoma has made scarce progress over the past decades. This is partly due to the combination of the tumour’s heterogeneity, and the inability of the current animal models to accurately depict this. This project was a pilot study into the development and characterisation of a novel cell line model of glioblastoma, which could be transplanted into immune competent mice, in order to study the disease.

An immortalised C57BL/6 astrocyte cell line, with an EGFP transgene, was used as the base to add glioblastoma specific mutations. To produce a ‘classical-like’ glioblastoma model, a knockout in Pten was induced, onto which two separate lines the human oncogenes, EGFRVIII and RAS V12, were stably expressed. ‘Secondary-like’ models were created with a knockout of P53, and the stable transfection of IDH1R132H.

The ‘classical-like’ cell lines were assessed for how well they mimicked a classical glioblastoma. The Pten knockout cell line showed an increased proliferative and metabolic rate compared with the astrocytes and a significant increase in clonogenicity. The addition of RAS V12 to the cells showed an increased migratory capacity; and the Pten + EGFRVIII cell line had a tendency towards an increased proliferation. The ‘secondary-like’ cell lines were assessed for their survival-related phenotypes. The P53 cell line showed a decreased proliferative rate, but with an increased metabolic rate and clonogenic ability. The introduction of the IDH1 mutant protein resulted in a decreased rate of G2 arrest in response to ionising radiation.

These cell lines recapitulated what is seen in human glioblastoma tumours and show potential as a transplantation model. Future research will investigate the tumorigenicity of these cell lines.
