The research aims to theoretically substantiate, develop, and present a structural-functional model for digital culture formation among senior school students within the upbringing environment of a general education institution. The article presents a designed model that includes methodological-target, motivational-value, activity-based, and control-analytical blocks. The school’s upbringing environment is viewed as a key factor ensuring the formation of digital culture among high school students. The scientific novelty of the study lies in the justification and implementation of the unity of systemic-axiological, culturological, and technological approaches as a methodological strategy. This allows the process of digital culture formation in senior students to be represented as a holistic structural-functional model. As a result of the study, the content and interconnections of the model’s structural blocks are defined, and criteria and indicators for assessing the level of digital culture formation in senior school students are identified (motivational-value, cognitive, activity-informational, and reflexive-evaluative).
The efficiency of recombination is of crucial importance for the existence of ultracold plasmas (UCP), particularly those formed in the magneto-optical traps. Unfortunately, the equilibrium thermodynamic treatment of the ionization–recombination processes is inappropriate for the evolving UCP clouds, while the straightforward kinetic simulation encounters the problem of the huge difference in the spatial and temporal scales for free and bound motion of the electrons. As a result, only the “virtual” electron–ion pairs are usually reproduced in such modeling, and it is necessary to employ some heuristic criteria to identify them with the recombined atoms. It is the aim of this paper to present the first successful ab initio simulation of the non-equilibrium recombination in the evolving UCP plasmas. We employed a special algorithm, which is based on using the “scalable” reference frame, co-moving with the expanding substance. Then, the recombination events are identified by a series of sharp equidistant peaks in the kinetic and/or potential energies, which are caused by the captured electrons passing near the pericenters of their orbits, and this is confirmed by a detailed inspection of their trajectories. Thereby, we were able to trace the real—rather than “virtual”—electron–ion pairs, and the total efficiency of their formation was found to be about 20%, which is in agreement with the laboratory measurements.
Background and relevance. The relevance of this study stems from the need to assess both the opportunities and risks associated with the use of digital technologies in everyday life. Currently, there is a limited body of empirical research examining cyberloafing (using smartphones for personal purposes during work or academic activities) and phubbing (using smartphones during face-to-face social interactions) in relation to individuals’ perceptions of their own happiness. Existing scientific literature presents conflicting evidence regarding the association between digital technology use and subjective happiness. Objective. To investigate the relationship between individuals’ conceptions of personal happiness and academic cyberloafing and phubbing behaviors. Hypothesis. Based on existing theoretical and empirical studies, we hypothesized that conceptions of personal happiness are associated with levels of academic cyberloafing and phubbing. Methods and materials. Empirical data were collected using the following instruments: the Cyberloafing Scale developed by Y. Akbulut et al. (Russian adaptation by N.V. Sivrikova), the Phubbing Scale by Karadağ et al. (Russian adaptation by D.S. Sivrikova and N.V. Sivrikova), and a supplementary questionnaire. Data analysis employed correlational analysis and CHAID (Chi-squared Automatic Interaction Detection) decision tree modeling. The study involved 248 participants aged 14 to 25 years. Results. The findings contribute to the current understanding of youth happiness in the context of media consumption. Happiness levels were found to be associated with participants’ gender and age. Moreover, specific conceptions of happiness were significantly linked to both phubbing and academic cyberloafing behaviors. In particular, individuals who defined happiness as achieving balance and harmony exhibited lower levels of academic cyberloafing. Additionally, women who associated happiness with safety and peace demonstrated lower levels of phubbing. Conclusions. The results confirmed the existence of a relationship between conceptions of personal happiness and academic cyberloafing. A negative correlation was found between conceptions of personal happiness and academic cyberloafing and phubbing.
The Internet has given start to new types of communication systems and language contexts, one of which is Telegram discourse. The increasing popularity of this messenger makes it an urgent academic task to describe its language. The authors compared the stylistic features of Russian and English e-communication in Telegram publications. The article reviewed available definitions of the term Telegram discourse in modern media linguistics in order to define the features that make it different from the language of other online platforms. The Russian and English Telegram publications covered a wide variety of topics (psychology, lifestyle, literature, politics, journalism, art, cinema, TV shows, fashion, education, etc.) chosen by continuous sampling. The comparative study made it possible to define the universal aspects while revealing the language-specific stylistic peculiarities. The comparative stylistic analysis covered all linguistic levels, i.e., graphics, phonetics, syntax, vocabulary, and semantics. The research revealed language-related patterns in the use of stylistic devices and expressive means on phono-graphical, lexical, and syntactical levels. The phono-graphical level of Telegram texts was found rich in graphons, capitalization, multiplication, and onomatopoeia. The lexical level contained metaphors, allusions, irony, and idioms. The syntax was associated with gradation, parallel constructions, and rhetorical questions. In general, the expressive means and stylistic devices used in publicistic Telegram discourse was full of cliches. However, Russian and English Telegram stylistics differed on every level. The research results might be used in university courses of stylistics, Internet linguistics, lexicology, and foreign languages.
