Предпрогнозний аналіз часових рядів методами фрактального аналізу та фазових траєкторій

The procedure of the qualitative analysis of time series, for which the hypothesis of trend existence isn’t confirmed, with application of the methods of nonlinear dynamics and the theory of chaos, is presented. The real time series characterizing prevalence of various skin diseases in Ukraine are considered. The basis for similar researches is Takens’s theorem. The randomness of the studied dynamical system given by time realizations is established by means of Lyapunov’s indicator. The state stability is estimated by Hausdorf’s fractal dimension and the fractality index. Visual evaluation of the time series was carried out by means of the phase trajectory restoration procedure. As a result of the analysis of phase pointsin the phase space the split attractor is indicated, which gives the chance to speak about its bifurcation.Запропоновано процедуру якісного аналізу часових рядів, для яких не підтверджується гіпотеза про наявність тренда, із застосуванням методів нелінійної динаміки, теорії хаосу. Розглянуто реальні часові ряди, що характеризують поширення різних шкірних захворювань в Україні. Обґрунтуванням для подібних досліджень є теорема Такенса. Хаотичність досліджуваної динамічної системи, що задана часовими реалізаціями, встановлена за допомогоюпоказника Ляпунова. Оцінка стійкості стану оцінювалась фрактальною розмірністю Хаусдорфа і індексом фрактальності. Візуальна оцінка часового ряду проводилась за допомогоюпроцедури відновлення фазових траєкторій. В результаті аналізу фазових точок фазового простору виявлено розщеплений атрактор, що дає можливість говорити про його біфуркацію

Speech Behavior and Multimodality in Online Communication among Teenagers

The article presents an analysis of online interactions among teenagers. The development of online communication is an important factor in the process of formation and reproduction of new social ties and relationships. Continuous online communication is becoming an important feature of everyday life. Online communication affects communication in general, developing its new requirements and standards. The polymetodic research consists of a questionnaire survey method and a content analysis method. The questionnaire was conducted among 50 teenagers aged 13-15, studying in schools of Ekaterinburg and regularly using the Internet to communicate with peers. A content analysis of online dialogs (n = 40) presented by the survey participants was also conducted. The research data proclaims social networks to be the most efficient tool of communication among modern teenagers. The most popular one is Vkontakte, which is used to chat and learn modern vocabulary. The daily routine, including the learning process, is the main topic of communication. Teenagers hardly change their speech behavior, since online and offline communication occurs mainly in the same reference groups. Teenagers also use audio-visual materials, emojis, stickers, etc., to complete their messages and express their emotional state. Keywords: online communication, teenagers, speech behavior, multimodalit

Consumo de agua en el sector hotelero en destinos insulares: el caso de Puerto de La Cruz

Máster Universitario en Dirección y Planificación del TurismoTourism alongside with its contribution to economic and social development may have negative impacts on local resources, including water, which is especially relevant in island destinations and areas of water scarcity.

Vladimiro Piskorsky: historiador hispanista y articulista, defensor de la autonomía universitaria (en el 150 aniversario de su nacimiento)

El presente artículo se dedica a Vladimiro Piskorsky (1867-1910), el gran historiador ruso, autor de investigaciones fundamentales para la historia de España, estudiante de la Universidad de Santo Vladimiro en Kiev, catedrático del Instituto de Historia y Filología en Nezhin (1899-1905), y de la Universidad Imperial de Kazán (1906-1910), miembro emérito de la Real Academia de Ciencias y Artes de Barcelona (Academia de Buenas Letras de Barcelona) (1901). Se siguen las vías de desarrollo de su interés hacía España y su historia con hincapié en el destino de la educación universitaria española. Es la primera vez que su artículo “Universidades españolas” (1896), escrito mientras estuvo de viaje académico en España, se introduce en los círculos históricos. Basándonos en el patrimonio epistolar de Piskorsky, hemos seguido su itinerario en España y hemos reproducido el círculo de sus contactos españoles. Se muestra la relación entre las observaciones y reflexiones del viajero, y las preocupaciones de los intelectuales españoles conocidos como Generación 98. Completamos el estudio con las vías que Piskorsky ofrece como posible remedio para salir de la crisis universitaria tanto a España, como a Rusia. Se trata en primer lugar de las condiciones básicas de la autonomía universitaria que implican libre determinación para establecer programas y planes de estudio, líneas de investigación y políticas culturales. 

Digital fears experienced by young people in the age of technoscience

With the advance of technoscience, digital technologies have started to reshape the traditional array of social fears experienced by younger generations by triggering the appearance of new, digital fears. In this article, we undertake a sociological analysis to investigate the concept of digital fears both theoretically and empirically. Our survey conducted among Russian young people aged 18-30 in 2020 (N = 1050, Sverdlovsk region, Russian Federation) showed that fear is a distinctive characteristic of the social well-being of this generation. Moreover, fear tends to become more pronounced both quantitatively (i.e., the frequency of emergence) and qualitatively (i.e. the emergence of new types). The identified digital fears of young people allowed us to draw their typology. Depending on the specifics of digital threat, the following types were distinguished: those associated with impact and control, crime and security, communication and activity, technology and innovation, and social inequality. We show that the expanding range of social fears leads to the formation of catastrophic thinking in young people, thereby affecting the level of social well-being and distorting the image of the future
