Negative impact of digital freedoms on Russian youth

Negative impact of Digital environment on the Youth is being increasingly mediated via novel communication technologies due to the uncontrolled channels of communication (digital freedoms). The analysis of this phenomena was conducted on the media texts (2016-2021) with a destructive component (murder, suicide, violence, revenge) with the aim of realization objective verbal behavioral model of generation Z as a new identity “online brain” in the format of transforming the axiosphere of adolescent discourse. We used objective pragmalinguistic analysis based on the specific perlocutionary intention of the sender of the text/information, accepted in pragma linguistic the last few years, as well aslexico-semantic method, contextual methods of analyzing words and constructions at the semantic level, the syntactic and descriptive analysis of the text according PMG (predicative-modal group). It was proved that axiological shifts in virtual reality caused the creation of new “online brain” formation with its own axiologem reflected in Real image of a digital adolescent.

Life-history traits and intra-cohort divergence of clearhead icefish (Protosalanx chinensis), indicating cannibalism increased fitness

Cannibalism is considered one of the causes of intra-cohort size divergence in fish and is usually believed to result in increased fitness in terms of survival and reproduction, but direct evidence of this is lacking. Population demographics of the clearhead icefish (Protosalanx chinensis) from Lake Xingkai (Khanka) were investigated for one year. Size-frequencies exhibited a bimodal distribution from July through January, where the population diverged into an upper and a lower modal group based on size. Stomach content analysis confirmed the occurrence of cannibalism, where fish belonging to the larger, upper modal group preyed upon those of the smaller, lower modal group. We found P. chinensis does not spawn until all of the oocytes have reached maturity and then a single spawning event occurs although the oocytes may develope asynchronously in the ovary. Upper modal group females matured slightly earlier than those of the lower modal group, and reproductive investment was considerably greater in the upper modal group than the lower modal group. The lower modal males made up the majority of the population after the spawning period, which meant they may have few opportunities to participate in reproduction. Therefore, piscivory and cannibalism of P. chinensis appears to have increased fitness of the fish belonging to the upper modal group and greatly reduced the fitness of those belonging to the lower modal group.

Anthropometry and Size Groups in the Clothing Industry

It appears that from generation to generation the anthropometric dimensions of the human population are changing. The aim of this paper was to examine the extent of these changes and the need for generating updated measurements for the clothing industry. The clothing industry uses mannequins and avatars to represent the modal group of the population. The industry tends to use three different categories for the human body shape (endomorphic, mesomorphic, and ectomorphic). The clothing industry should focus on specific measurements of the body rather than general categories and create more body shapes to satisfy customer needs. The paper also aimed at showing the problems faced by clothing designers. The traditional way of measuring takes into account only selected dimensions of the human body; this does not reflect the “true” overall body shape. The dimension tables used by the apparel industry are based on the fourth anthropometric photograph taken between 1987 and 1989. These tables are still in the use currently; however, after 30 years they are outdated and should be revised for the young contemporary generation. This study can be used for the development of new dimension tables as well as defining methods aimed at improving the quality of measurements for clothing engineering purposes. This is an important issue, because the National Institute of Anthropometry does not deal with such problems (the measurements are conducted mainly for understanding the human body shape rather than any other application), which means that anthropometric measurements are not ideally suited to applications of clothes fitting.
