Sentiment analysis method of consumer comment text based on BERT and hierarchical attention in e-commerce big data environment
Authors: Chang Wanjun , Zhu Mingdong
Published: January 2024

This study proposes an emotional analysis method of consumer comment text based on Bidirectional Encoder Representations from Transformers (BERT) and hierarchical attention. First, using the BERT pre-training model, the left and right contextual information is fused to enhance the semantic representation of words and generate dynamic word vectors containing contextual semantics. Second, the bidirectional long short-term memory network is used to obtain the sequence feature matrix, and the sentence representation and the text representation are obtained using the two-layer long short-term memory. Finally, the local attention mechanism and the global attention mechanism are introduced into the sentence representation layer and the text representation layer, respectively, and the text emotion of consumer comments is classified by softmax. Experiments show that the accuracy of the proposed method in Laptop data set is 93.01% and that in Restaurant data set is 92.45%. Therefore, the performance of the proposed method in the emotional analysis of consumer comment text is significantly better than that of the comparison method.

Analysis of individual nanoscale block copolymer vesicles by atomic force microscopy combined with time-resolved fluorescence microscopy
Authors: Schönherr Holger , Druzhinin Sergey I. , Handschuh-Wang Stephan , Wesner Daniel
Published: January 2024

We report on the analysis of individual dye loaded block copolymer (BCP) vesicles via a combination of confocal laser scanning microscopy (CSLM)/fluorescence lifetime imaging microscopy (FLIM) on the one hand and atomic force microscopy (AFM) on the other hand. AFM measurements on ATTO 647N-loaded poly(styrene-block-poly(acrylic acid)) (PS115-b-PAA15) vesicles were carried out with high spatial resolution and afforded morphology and dimensions of BCP vesicles on solid substrates. By contrast the CSLM and FLIM data are diffraction limited, but from the time resolved fluorescence data information on the local vicinity of the reporter dye can be extracted. In the combined experiment individual dye-loaded vesicles and vesicle aggregates were discerned, analyzed metrologically by AFM and in more detail by CSLM and FLIM. On the basis of FLIM data the partitioning of the reporter dye was analyzed. The dye resides preferentially in the hydrophilic corona inside the vesicles. The dye concentration in the polymersome was about 90 times higher than in the solution used for encapsulation. These results underline that the combination of AFM with sensitive optical techniques, especially FLIM, is a promising approach for obtaining a deeper understanding of molecular interactions and nanoenvironments in supramolecular macromolecular structures and beyond.
Harmonic current suppression method of virtual DC motor based on fuzzy sliding mode
Authors: Shang Lisha , Jia Yajuan , Zheng Liming , Xie Gaoshang
Published: January 2024

In the operation of power grid, the low frequency subharmonics in power lines are easy to cause harmonic current problems. A harmonic current suppression method is constructed based on fuzzy sliding mode and virtual DC motor (VDC). First, the adaptive linear network is introduced to compare and analyze the output value and the actual value in the power line, and the possible harmonic current is obtained, which is detected and discretized. After that, this study adopts Fuzzy sliding mode control (FSMC) strategy for VDC, uses FSMC to participate in on-off control of VDC, and then realizes the suppression of harmonic current in VDC ports. In addition, the model also uses the circuit superposition theorem and the amount of harmonic data to be compensated by FSMC. The whole method uses VDC control technology to ensure the voltage stability of DC bus and load side when the load changes. In this physical experiment, harmonic current generated by load disturbance is eliminated by reducing DC harmonic voltage, so as to achieve the suppression of DC port harmonic current. Experimental results show that the third and fifth harmonics in power lines can be eliminated by this method to a large extent. Therefore, the proposed method can accurately detect and eliminate the harmonic current caused by sudden load change, and then realize the suppression of VDC harmonic current.

Published: January 2024

The world today presents significant environmental concerns for humans, such as smog and warmer temperatures, but we also need to think about how to accomplish economic growth that is sustainable. Therefore, this exploration researches the asymmetric effect of renewable energy consumption, economic growth and financial development on carbon emanation in the emerging economies. For this reason, this investigation uses Panel ARDL and PMG estimator. The consequences of PMG estimator demonstrate that information and communication technologies reduce the carbon emanations in the sample region. Additionally, renewable energy consumption also impedes the carbon emanations. The results also suggest that financial development additionally builds the carbon emissions but the impact is very minor. Finally, economic growth and population are also contributing toward carbon emissions. The power effective recommendation is vital to present the ICT assistance to confine the utilization of obsolete machinery for power generation.

Published: January 2024

O objetivo deste artigo é identificar os fatores dos subsistemas do sistema sociotécnico (SSS) que funcionam como impulsionadores e/ou inibidores para a adoção da transformação digital (TD) no contexto das pequenas e médias empresas (MPEs). A lente teórica dos sistemas sociotécnicos complexos é utilizada para entender o comportamento desses fatores na performance do processo da TD nas MPEs. Para isso, foi realizado um estudo de caso múltiplo envolvendo quatro agentes de inovação, os quais aplicaram a metodologia do projeto com foco em TD em 32 MPEs da região metropolitana de Porto Alegre/RS. Este estudo foi conduzido através de relatórios disponibilizados pelos Agentes, os quais incluíam check-up digital que possui 6 dimensões: tecnologias e habilidades digitais, comunicação e canais de venda, organização e pessoas, estratégia, dados e inteligência analítica. De acordo com os resultados do estudo, foi confirmado que as MPEs que possuem uma alta orientação pelos SSS são mais propensas a implementar tecnologias para a TD. Com base nessas descobertas, o estudo oferece recomendações gerenciais para melhorar o processo de TD nas MPEs.

Analysis of Indonesian Exports Demand in the ASEAN Region
Authors: Wau Taosige
Published: January 2024

The dynamics of a country's exports are determined not only by the supply side but also by the demand side. This research examines the influence of the demand side on Indonesia's exports. Its primary aim is to analyze the effects of per capita income, inflation, and the exchange rates of partner countries on the demand for Indonesia's exports in the ASEAN region. The data used is panel data covering the observation period from 2000 to 2021, encompassing nine ASEAN member countries trading partners with Indonesia. The analytical method employed is a panel regression model using a random effects approach, estimated through the EGLS method. The findings indicate that an increase in per capita income, inflation, and the appreciation of partner countries' currencies against the USD can stimulate the demand for Indonesia's exports in the ASEAN region, albeit to varying degrees.
Institutional Quality and Economic Growth in Muslim Countries
Authors: Yunan Zuhairan Yunmi
Published: January 2024

This research analyzes the link between institutions and growth in a selection of Muslim nations to determine which elements have the most influence. The study spans 20 years, from 2002 to 2021, and employs a cross-country analysis to conclude that only three aspects of institutional quality (government effectiveness, political stability and lack of violence/terrorism, and voice and accountability) are strongly related to economic growth. The findings, obtained through a dynamic panel setting, reveal that most control variables exhibit significant effects consistent with expected outcomes. However, the investment coefficient, while positive, lacks statistical significance, suggesting that the impact of investment on economic growth in Muslim nations is not robust enough to be statistically validated. Moreover, the study delves into institutional quality's impact on economic performance and finds that three out of five variables significantly influence growth. Government effectiveness, political stability, and absence of violence/terrorism demonstrate substantial positive correlations, particularly at the 1% significance level. While still positively related to economic growth, regulatory quality and the rule of law only exhibit significance at the 10% level. To further understand the impact on economic development, this paper advises that future research explore numerous institutional quality criteria and segregate Muslim countries based on their political systems.
Resocializacijos įgyvendinimo problemos ir galimybės Lietuvos kalėjimuose
Authors: Aleknevičienė Jolanta , Kalinauskaitė Ignė
Published: January 2024

Lithuania‘s strategic documents point out that the main purpose of the execution of sentences is the resocialisation of convicts. The article analyses the problems and possibilities of the implementation of resocialisation of convicts in Lithuanian prisons today, based on the ideas of positivist and critical criminology. The research comprised an analysis of scientific literature and strategic documents in Lithuania, and an empirical qualitative study, which included twenty semistructured interviews with Lithuanian prison staff and experts from the penitentiary system. The data analysis was based on thematic analysis. The study reveals that resocialisation as a priority becomes a secondary goal of imprisonment during implementation, pursued in a demotivating and desocialising prison environment and punitive culture. The gap between the prison‘s stated objectives of resocialising prisoners and the human and financial capacity to achieve this is noted. Positivist and critical criminology ideas broaden the perception and analysis of resocialisation as a phenomenon and make it possible to rethink the functional and institutional distinction between the punishment of convicted persons and their treatment, assistance, and motivated personal transformation as different activities. The study suggests that the success of resocialisation of an individual requires the disaggregation and implementation of the stages of resocialisation, not only in prison but also in institutions that focus on helping without retribution and punishment.

Published: January 2024

Giant pyonephrosis (GP) is a rare and severe form of pyonephrosis characterized by a massive enlargement of the affected kidney due to the accumulation of infected fluid. This study presents case of a 51-year-old male patient with giant pyonephrosis who underwent nephrectomy as treatment. The clinical manifestations of giant pyonephrosis are nonspecific, necessitating the use of imaging and laboratory techniques to aid in diagnosis. Nephrectomy is the preferred treatment option for these patients. One week after nephrectomy, the laboratory results showed improvements. Making the right treatment decision is challenging in this particular case.
Elementos para definir un modelo de ocupación del territorio en las ciudades colombianas
Authors: Sánchez Torres Zuly Ximena , Araque Solano Alex Smith
Published: January 2024

Un modelo eficiente de ocupación del territorio es un acuerdo colectivo que supera la dualidad de elección entre compacto o disperso y se centra en las posibilidades de financiamiento de los costos de la aglomeración. Elegir los costos como variable central en la definición de la ocupación indica que su determinación es política y no técnica. En este artículo se evalúa la densidad de 1101 municipios de Colombia en su categorización de ruralidad del sistema nacional de ciudades para el año 2018 y se identifican dos instrumentos de política con los cuales las administraciones locales puedan modular la ocupación del territorio; el tamaño medio de predio urbano y el valor catastral urbano. El desbordamiento de los centros de los distintos sistemas de ciudades sugiere decisiones políticas que no han sido responsables debido a la baja asociación entre densidad y tributación.
Financierización inmobiliaria y nuevas formas de habitar. Articulaciones teóricas para su abordaje desde Buenos Aires
Authors: Granero Realini Guadalupe
Published: January 2024

Un número creciente de agentes financieros globales encuentra en la producción urbana un ámbito de reproducción de capitales cada vez más seguro, eficiente y redituable. El proceso de financierización inmobiliaria está promoviendo cambios en las tipologías arquitectónicas que transforman las formas de habitar desde una lógica económica dominante. Así, las nuevas tipologías no son solo un mero producto de cambios culturales y sociales en las formas de habitar, sino que están atravesadas por procesos macroeconómicos, de escala global, donde la lógica financiera opera un nuevo nivel de mercantilización de la producción urbano-habitacional. La presente investigación se inserta en desarrollos contemporáneos que procuran hacer lecturas transversales entre el circuito de las finanzas y el de la producción edilicia, en el sentido de lo que algunos autores definen como complejo inmobiliario-financiero. Dentro de la creciente producción teórica que analiza las dinámicas de la financierización en las ciudades, este estudio busca explorar posibles relaciones desde las transformaciones espaciales y los impactos sociales que de ellas derivan.
Da injustiça educacional às políticas afirmativas para a educação superior pública no Brasil
Authors: Chaves Batista Neusa
Published: January 2024

O objetivo deste ensaio é abordar algumas causas de injustiças geradas pelo sistema educacional brasileiro que ressoam no ingresso à educação superior pública do País. Tais injustiças acarretaram a implementação de uma política afirmativa com cota socioeconômica, étnica, racial e para pessoas com deficiência (PcD), com o intuito de equalizar as oportunidades educacionais ao acesso à educação superior para as estudantes e os estudantes egressos de escolas públicas. A abordagem teórico-metodológica utiliza-se da análise crítica baseada em referenciais que discutem conceitos de justiça e injustiça social e escolar. Por esta via interessa-se em explicitar como o poder, a dominação e a desigualdade social são estabelecidos, reproduzidos e combatidos. A argumentação é desenvolvida de modo a dar ênfase à relevância social das políticas afirmativas. A desigualdade educacional na sociedade brasileira relaciona-se, explicitamente, com a injustiça socioeconômica e, de modo interseccional, com marcadores raciais; reforçando a dedução lógica de que precisaremos de políticas afirmativas para o ingresso de estudantes de escolas públicas na educação superior pública por tempo indeterminado.
Significados y perspectivas en modelización matemática de un cuerpo docente formador en Enseñanza de la Matemática de una universidad pública costarricense
Authors: Chavarría-Vásquez Jesennia , Gamboa Araya Ronny
Published: January 2024

Las concepciones que presenta el profesorado sobre modelización matemática inciden en la manera en la cual el proceso matemático se aborda en el aula y en las estrategias de enseñanza utilizadas. El objetivo de esta investigación fue caracterizar el significado y perspectivas en modelización matemática de un grupo docente formador de la carrera Enseñanza de la Matemática. El estudio fue cualitativo. Se aplicó una entrevista virtual a 28 docentes, en el segundo semestre del 2021. El instrumento aplicado contó con la anuencia de las personas docentes a participar de la investigación, e incluía una descripción sobre la confidencialidad de la información. Para el análisis de la información se utilizó el análisis de contenido. Dentro de los resultados se puede mencionar que el significado que le otorgan las personas docentes formadoras al proceso de modelización está ligado a la resolución de problemas, sin una relación estrecha con el contexto que se plantea. Dentro de las dificultades que mencionan y que inciden en el estudiantado al momento de enfrentarse a problemas de modelización, está la comprensión del problema que, en opinión de estos, se debe a una carencia de conocimientos algebraicos. Se determinó que el planteamiento de problemas con un conocimiento matemático específico, para el tratamiento o uso de datos, es una de las estrategias de enseñanza más utilizadas para el abordaje de la modelización matemática. Además, se indica que, para la incorporación de la modelización en los planes de estudio de formación de docentes de matemática, es necesario abordar el conocimiento de estos sobre los procesos de modelización, así como un adecuado planeamiento e incorporación de este tipo de actividades.
Marco competencial para la evaluación del desempeño profesional docente en la Universidad de Costa Rica
Authors: Zamora Serrano Evelyn
Published: January 2024

La consolidación de la cultura de evaluación y de calidad en la Universidad de Costa Rica (UCR) requiere de la reflexión constante de sus estrategias y mecanismos de evaluación. El objetivo de este artículo fue dar a conocer una propuesta de conceptualización de docencia universitaria y de competencia profesional docente, así como de las dimensiones que la componen, en función del contexto y de las necesidades actuales, para establecer recomendaciones con respecto a la actualización del perfil profesional y del proceso de evaluación del desempeño docente en la UCR. Esto con el fin de fortalecer el proceso de evaluación del desempeño docente, contribuir a la mejora del desarrollo profesional de la persona docente y orientar los procesos de formación de la docencia en la Institución. La investigación se realizó entre el año 2021 y 2023, con la participación de 282 docentes de diferentes áreas del conocimiento. En cuanto a su enfoque, se trató de un estudio del tipo cualitativo e ideográfico, no generalizable ni explicativo respecto a otros casos evaluativos. Es una investigación descriptiva con uso de técnicas de revisión bibliográfica, discusión en grupos y encuesta. Los resultados revelaron que la definición construida para docencia universitaria abarca los aspectos esenciales para una buena docencia, y que todas las características que aborda la literatura están contenidas en alguna de las dimensiones sugeridas por el Centro de Evaluación Académica (CEA). En las conclusiones, se recomendó utilizar tal definición como fundamentación teórica en nuevos instrumentos de evaluación del desempeño docente y que la amplitud de las dimensiones competenciales haga necesaria su operacionalización.
Direito à educação e à saúde nos cotidianos das infâncias em risco humanitário
Authors: Eyng Ana Maria , Pimpão Ferreira Bárbara , Morais Tosta Priscila , Gomes Alves Mörking Tiago
Published: January 2024

Este artigo analisa os riscos sobre os direitos da infância, com ênfase na educação e na saúde em contextos de situação humanitária circunscritos pela pobreza infantil, aliada à crise sanitária pandêmica. O argumento baseou-se na pergunta: segundo a percepção dos estudantes, quais os impactos da pandemia e do período pós-pandemia na educação e na saúde? Portanto, o objetivo do estudo foi mapear as percepções de estudantes sobre seus Direitos nos cotidianos, em seis diferentes países latino-americanos. Os dados empíricos foram obtidos por meio de formulários online (com perguntas, abertas e fechadas) via Google Forms, aplicados em duas etapas de investigação qualitativa, realizadas no segundo semestre de 2020 e de 2022. A primeira etapa abrangeu 504 estudantes da educação básica (10-18 anos), de oito instituições de ensino e a segunda 462 de treze instituições, também da educação básica. Assim, as contribuições de 966 estudantes são discutidas neste texto, em diálogo com as referências bibliográficas e documentais. As questões fechadas foram sistematizadas estatisticamente e a análise de conteúdo foi aplicada às questões abertas (Bardin, 2009), como um todo os dados são analisados sob abordagem qualitativa. Ao se manifestarem sobre os Direitos necessários em seus cotidianos, os estudantes destacam o direito à educação e à saúde como os mais prioritários. Tais percepções revelam especificidades das comunidades educativas e os desafios vivenciados na garantia de Direitos nos espaços cotidianos, que afetam os processos de acesso, permanência e resultados da educação, bem como os problemas de saúde física e emocional, surgidos e/ou agravados no período. Nesse contexto, portanto, aumentaram e se agravaram os riscos, num cenário no qual já se identificava uma histórica fragilidade na garantia dos Direitos das crianças, especialmente quanto aos direitos à educação e à saúde.

Engagement agéntico: un análisis sobre su uso en el contexto educativo hispanohablante
Authors: Guzmán Arellano Cintya , Solar-Alveal Benjamín , Maluenda-Albornoz Jorge
Published: January 2024

La necesidad de dar cuenta del componente volitivo en el Engagement académico ha traído como consecuencia la propuesta de una cuarta dimensión denominada engagement agéntico. Sin embargo, su uso en el contexto hispanohablante ha sido escaso, poco claro e inconsistente. El objeto de este estudio es analizar los usos del concepto engagement agéntico en la investigación disponible en el contexto educativo latinoamericano. Se realizó un ensayo analítico basado en una revisión de artículos recientes en la temática de engagement agéntico aplicado en contextos hispanohablantes. La discusión realizada plantea que la literatura actual coincide con la delimitación teórica original del constructo, pero presenta una aproximación principalmente funcional que excluye elementos relevantes en su aplicación vinculados con el disfrute e interés personal del estudiante, la relación con sus pares en el aprendizaje y los comportamientos de agencia fuera del aula o no observables. Se concluye que la investigación hispanohablante necesita profundizar en las variables intrínsecas e intereses personales del alumno al trabajar el engagement agéntico, así como incorporar las conductas externas al aula de clases y el trabajo entre pares como una manifestación relevante y esencial del constructo, dada su relación significativa con el desarrollo de estados motivacionales intrínsecos en el alumno.

Let $({\xi _{1}},{\eta _{1}})$, $({\xi _{2}},{\eta _{2}}),\dots $ be independent identically distributed ${\mathbb{N}^{2}}$-valued random vectors with arbitrarily dependent components. The sequence ${({\Theta _{k}})_{k\in \mathbb{N}}}$ defined by ${\Theta _{k}}={\Pi _{k-1}}\cdot {\eta _{k}}$, where ${\Pi _{0}}=1$ and ${\Pi _{k}}={\xi _{1}}\cdot \dots \cdot {\xi _{k}}$ for $k\in \mathbb{N}$, is called a multiplicative perturbed random walk. Arithmetic properties of the random sets $\{{\Pi _{1}},{\Pi _{2}},\dots ,{\Pi _{k}}\}\subset \mathbb{N}$ and $\{{\Theta _{1}},{\Theta _{2}},\dots ,{\Theta _{k}}\}\subset \mathbb{N}$, $k\in \mathbb{N}$, are studied. In particular, distributional limit theorems for their prime counts and for the least common multiple are derived.
Elvégzetlen feladataink: hiányzó definícióink
Authors: Molnár F. Tamás
Published: January 2024

Bevezetés

Egy, a sebészetben alkalmazott leggyakoribb fogalmaknak szentelt cikksorozat bevezető tanulmánya ez. A látszólag egyértelmű definíciók vizsgálatakor kiderül, hogy vagy egyáltalán nem is léteznek, annyira maguktól értetődők (pseudoaxiomák), vagy olyan sok van belőlük, hogy nincs igazi. A javasolt definíciók munkapéldányok, további javításra várnak. Az első két javaslatot tesszük közzé: a sebészet és a kompetencia kérdésében.

A sebészet fogalma

A sebészet a medicina azon válfaja, melynek megkülönböztető tulajdonsága, hogy szövetegyüttesi szintű sértés révén, azaz a testet alkotó strukturális elemeket eltávolító/átalakító módokat alkalmaz célja elérésében: a kórismézésben és a kezelés nyújtásában.

A sebészi kompetencia fogalma

A sebészeti kompetencia az állam mint közhatalom által hitelesített bizonyított cselekvőkész tudásösszesség birtoklása, kerete a szakvizsga.

Konklúzió

A tiszta, egyértelmű definíciók hiánya akadályozza a tudományos és szakmai diskurzust. Megalkotásuk, elfogadásuk közmegegyezés kérdése. További kísérletek következnek.

This paper presents an analysis of speech pauses occurring in selected political speeches, with a focus on both filled and silent types. The paper aims to highlight differences among pause categories in spoken language and assess potential gender differences. By analyzing speeches from male and female speakers in specific syntactic contexts, the paper reveals limited variations in fundamental frequency and pause duration. While certain subcategories exhibit slight differences in frequency, consistent patterns are lacking.
Findings indicate that filled, hesitation, politeness, and perturbation pauses tend to be longer, whereas specification and personal stance pauses tend to have lower frequencies. Enumeration, opposition, and segmenting pauses strategically support a speaker's point, aligned with sentence structure. Investigating fundamental frequency trends before pauses demonstrates that a decrease in frequency signifies unit culmination, while an increase suggests non-final positions within units.
The paper concludes that disparities exist among pause types, though differences between male and female speakers are generally minor. This emphasizes the need to consider multiple factors, including duration, frequency, and syntactic context, for comprehensive pause definitions. Overall, the paper provides insight into speech pause attributes, variations, and their significance in conveying meaning, thus enriching our understanding of speech patterns and communication strategies.
On the Fiscus of Justinian: To the Position of the Question
Authors:   Barnaul Orthodox Seminary, Serov Vadim
Published: January 2024

In the historiography of the Early Byzantium, the concept of “an Emperor’s fiscus” mismatches with the late ancient original. The fiscus was not a synonym for the state treasury, but it was simultaneously the funds for public purposes and private and personal resources. Emperors supported this ambiguous legal nature of fiscus, implying some specific targets of their policy. The balance varying between them between public and non-public constituents in the fiscus is called fiscal policy in its own sense. Emperor Justinian I carried out the same policy apropos the fiscus. As with some of his predecessors, he sustained the originally formed dual nature of the fiscus, consistently striving for the separation of private from public. Justinian admitted a little identification of the public function of fiscus and the state (public) treasure, but only on the level of abstract concepts. Thereby, the Emperor did demonstrate the separation of his personal and private property from the state. At the same time, the emperor’s personal property, as well as the fiscus as a whole, was a part of the nationwide resources from the point of view of Justinian I. Thus, the fiscal policy of Justinian was a continuation of the fiscal policy of Zenon and Anastasius I, but it also had a few features. They were expressed, in particular, in the use of an unusual term for Roman legislation, the “fiscus”, in a Greek way.
The Old Age is Not Joy: Documentary Evidence About Old Age and Elders in Mediaeval Byzantium
Authors:   Institute of World History of the Russian Academy of Sciences, Vin Yury
Published: January 2024

The representations about old age, displayed in Byzantine acts, are revealed in a slightly defined form. However, this problem constantly attracts the attention of Byzantinists. The fundamental interest is adverted to status of the so-called “elders”. Their position is studied in the inextricable connection between age, ethical and social motives of social activity and involvement of the “elders” in the government system, especially rural self-government. In this regard the social role of the “elders” seems to be especially significant. All references to them are characterized in the light of the estate belonging of the “elders” to monasticism and village habitants. The formation of the landlord’s estate and the strengthening of the feudal dependence of the peasantry conditioned the emergence of the seniormen, represented by so-called “protoelders”, as apparatus of the control over the paroikoi population of the seigniorial estate. The further perspective of the subsequent studying the “elders” consists in demonstration of the general development of their social activity. The content of the problems of the studied topic is represented in the sections of the article “Introduction”, “The age and the socio-cultural significance of the old age”, “The elders in the system of the rural management”, “The protoelders” and “Conclusions”.
Did Antiquity Disappear in the Cities of Asia Minor Long Before the Fall of the Roman Empire? (Book Review: Pont, A.-V. La fin de la cité grecque: métamorphoses et disparition d’un modèle politique et institutionnel local en Asie Mineure, de Dèce à Constantin / A.-V.

Published: January 2024

Introduction. The publication is a review of a monograph by Anna-Valerie Pont, Professor of the Sorbonne, devoted to an attempt to determine the time of the disappearance of an ancient city (polis) on the material of Asia Minor. Analysis and results. There is an extensive and complex source base of research in terms of composition and quality, which includes both scanty reports of late Antique and early medieval written heritage, as well as archaeological data, among which the author legitimately highlights epigraphic material. As criteria for the extinction in the city, it is the ancient indicators of public life that have priority: the decline in the functioning of self-government institutions by urban communities, a decrease in the activity of wealthy citizens in organizing spectacles, subsidizing essential products, an increase in the specific weight of imperial bureaucratic control and local management, an increase in the influence of Christians on public processes in policies. The review indicates that the French researcher actually ignored the evolution of municipal property (the degradation of which in the chronological framework under consideration was very modest). In fact, the evolution of such estates as curiales and plebs (whose position at the time under consideration was by no means catastrophic) was also left aside. The social historical realities in the monograph are touched upon only insofar as they are related to institutional elements (the work of city councils, the implementation of magistracies, etc.). The author of the review points out that such a method of analyzing late-antique processes is outdated and goes back to the Enlightenment views on the fall of the Roman Empire. The review focuses on the legitimacy of the priority of epigraphic monuments for the disclosure of the stated topic (due to the insufficiency of narrative sources). However, consideration of the reduction in the number of such monuments at the turn of the 3rd – 4th century (compared with the times of the classical Empire) as an indicator of the extinction of the antique parameters of the policy is doubtful.
The Structures Outside the Town Gate atop the Plateau of Eski-Kermen: Reality and Conjectures
Authors:   Institute of Archaeology of Crimea of the Russian Academy of Sciences, Zavadskaya Irina
Published: January 2024

Introduction. The architectural complex around the main (southern) gates of the city on the Eski-Kermen plateau in the mountainous Crimea was formed from the end of the 6th century to the end of the 13th century. It included structures that were different in architecture and purpose. Studying the remains of these structures, determining their role and chronology are important tasks in the study and reconstruction of the history of the city. Methods. The area around the gate was explored by N.I. Repnikov in 1929. Brief descriptions of the open remains of the structures are reflected in publications and archival documents. Based on the analysis of these descriptions and the study of the preserved rock foundations, first time in the historiography the article revises the widespread hypothesis about existence of the gate church in the medieval city on the plateau of Eski-Kermen in the mountainous Crimea. Analysis. Some researchers see an apse of this church in a rounded carved pit located in front of the main gate, east of the corridor carved into the rock leading to the city. Features of the architectural space at the city gates and the location of this clearing are likely to have its presence at the gate church. This felling arose simultaneously with the defensive structures near the gates in the end of the 6th c. As is known, gate churches as a type of church architecture appeared in the Eastern Christian world no earlier than the 10th or 11th centuries. Results. There is no reason to talk about the gate church on the plateau of Eski-Kermen. Directly at the entrance to the city (to the west of the passage) there was only one church-chapel of the 9th – 10th centuries, destroyed by an earthquake even before the onset of the city, burned at the end of the 13th century.
High-Performance Technique for Item Recommendation in Social Networks using Multiview Clustering

Recommender Systems have been widely employed in information systems over the past few decades, making it easier for each user to choose their own products based on their past behaviour. Data mining tasks and visualization tools regularly use clustering techniques in the scientific and commercial arenas. It has been shown that clustering-based methods are effective and scalable to big data sets. The accuracy and coverage of clustering-based recommender systems are, however, somewhat low. In this paper, we suggest an improved multi-view clustering method for the recommendation of items in social networks to overcome these problems. To create better partitions, the artificial Bees colony optimization algorithm (ABC) is first used to improve the initial medoids’ selection. After that, users are clustered iteratively using views of both rating patterns as well as social information using multiview clustering (MVC) (i.e. trust and friendships). Ultimately, a framework is suggested for evaluating the various options. This research study suggests a novel MVC clustering approach using the ABC optimization technique. The proposed ABC-MVC algorithm’s usefulness in terms of enhancing accuracy is demonstrated by experimental findings performed on a real-world dataset and it is observed that it performs better than the pre-existing techniques and baselines.

Localization, in both indoor and outdoor settings, represents a problem that has received increased attention lately. This paper presents the development, testing, and validation of an indoor localization system for 1/10 scale vehicles based on the Robot Operating System (ROS) and ArUco marker detection. It has a distributed architecture, consisting of tens of Raspberry Pi (RPi) singleboard computers running ROS nodes and fitted with cameras, that monitor a certain area of the 14x14 m plane. The developed system has been successfully used in three editions of Bosch Future Mobility Challenge, an international student competition, where the participants are required to implement autonomous driving functionalities in an environment resembling a real-life city on small-scale automated vehicles.
FRACTAL-BASED UWB-MIMO ANTENNA WITH RECONFIGURABLE BAND-NOTCHING CHARACTERISTICS

Published: January 2024

A multiple-input-multiple-output (MIMO) antenna-deploying fractal structure is presented for ultra-wide band (UWB) applications. Furthermore, one band notch (WLAN) is introduced on the radiating patch with a PIN diode to achieve reconfigurability. The antenna consists of two planar fractal elements on one side of the substrate along with the microstrip-fed line. The grounds of these elements are connected via a tiny strip on the other side to form a single ground. To reconfigure the notch, the PIN diode acts as a switch. When the diode is turned off, the antenna's impedance bandwidth exceeds 3.1-10.6 GHz, and the WLAN spectrum (5.15-5.725 GHz) is notched. The performance of the antenna is investigated by examining the reflection coefficients of the two ports. There are further measurements of antenna gain, VSWR, envelope correlation coefficients (ECC), and diversity gain (DG).
Choosing a Modern Foreign Language as a GCSE subject – is there a choice? Option boxes and other factors
Authors: Jones Delyth
Published: January 2024

The aim of the research which underpins this article is to identify the factors that influence pupils when choosing, or not choosing, to study a modern foreign language as a GCSE subject. In 2015, the document Global Futures was published by the Welsh Government to improve and promote Modern Foreign Languages (MFLs). However, statistics show that the numbers taking MFLs as a GCSE subject are continuing to fall (British Council, 2021). The Evaluation of Global Futures (Welsh Government, 2022a) acknowledged that not all the aims of the strategic plan were fully realised as no increase was seen in the number of pupils studying MFLs at examination level. This article focuses on one particular aspect of the data collected by the project, namely the factors that prevented pupils from choosing MFLs as a GCSE subject. Data was collected from 860 pupils in 10 secondary schools, and barriers at school level, such as option boxes and courses not running, were found to be key factors (Jones, 2021, Clayton, 2022). The perception that the subject was difficult was also a factor preventing pupils from choosing MFLs as a GCSE subject, and it should be noted that the foreign language for the pupils in this study (Fukui & Yashmina, 2021) was, at the very least, a third language. It is argued, in line with the British Council report (2021:6), that ‘urgent intervention’ is needed to reverse the decline in the numbers choosing to study MFLs as a GCSE subject. Some recommendations are offered on ways to increase numbers, with reference being made to such considerations such as choosing option subjects in Year 8, setting MFL classes and the need for more deliberate planning in order for pupils to succeed in learning a foreign language (Ofsted, 2021). The implications of the Curriculum for Wales and the multilingual and plurilingual approaches presented therein as ways to “ignite learners’ curiosity and enthusiasm” (Welsh Government, 2022b) are also considered.
