Features of the discursive environment as a source for creating meaning in online communication (using the example of social networks)

With the spread of online communication, more and more attempts are being made to study it as a process occurring in different discursive spaces. In the article, using the example of a single message hosted on several social networks, the discursive conditions and the possibilities of various social media to influence the content of the meanings, created within their environment, have been analyzed. The subject of the research was the discursive characteristics of representations of a single message in various social networks. The purpose of the paper is presentation of a theoretical and methodological approach for cross-platform analysis of social media discourse, which, if desired, can be expanded on a larger data file, taking into account the results of the qualitative critical discourse analysis of the case introduced. The method of critical discourse analysis (CDA) has been used, which allows you to identify and analyze social structures in the framework of dialectical relationships. In the course of the study and analysis, it was revealed, that even in the case, when using the variable capabilities of various social networks to create and transmit meanings is not a deliberate strategy of a single institution, its messages were filled with different semantic content, which means, that they have different convincing and legitimizing opportunities. This was due to the inability to avoid certain conditions of production, creation and distribution of content, set by the policy of social networks. Social network, as a communicative space, creates a mode of production, distribution and consumption of content, and in this mode, communication is already carried out. Due to the specific features of each network, one can say, that they create different discursive spaces

THE ACTION OF OIL, GAS CONDENSATE, DRILLING CUTTINGS AND DRILLING MUD ON THE BIOTA OF THE CASPIAN SEA

Conducted experimental studies on the effect of crude oil, gas condensate, drilling muds and cuttings on the zooplankton, on the plant pigments of phytoplankton, on the saprophytic microflora, as well as on representatives of ichthyofauna of the Caspian sea

Prostate cancer brachytherapy via ¹²⁵I microsources: assessment of the staff local radiation dose

The results of measurings of the local radiation doses of the most irradiated staff bodies regions - operator finger and palm skin, as well as breast region are given. The measurings are carried out via a method of thermoluminescent dosimetry with the use of highly sensitive detectors TLD-500K (Al2O3:C). It is ascertained that even in the biggest total activity of the sources (1221 MBq) and the largest duration of work of the staff with them without using X-ray shielding gauntlets, an absorbed dose (minus dose of the natural background radiation and taking into account an energy dependence of the detector sensitivity) equals 0,18±0,01 mGray (right hand thumb — the highest radiation level) and 0,01±0,0004 mGray (external surface of the left arm palm - the lowest radiation level) that doesn't pose radiohazard even in repeated working with sources (according to radiation standards 99). The normalized values of the absorbed doses (per unit time of the operator work and the sources activity unit) are represented, that allows using the obtained data for the other operating conditions of operator

Assessment of prevalence and monitoring of outcomes in patients with heart failure in Russia

The increasing prevalence of heart failure (HF) serves as a reverse side of the effective treatment for cardiovascular diseases (CVD) and increasing patient survival. Data on the epidemiology of HF and related mortality in Russia are limited. According to the EPOCHA trial (hospital phase), the prevalence of HF in the Russian Federation is 7%. HF can significantly contribute to cardiovascular mortality. However, its recognition is limited by the peculiarities of the mortality coding system in Russia. The article presents the authors’ view on the registration of HF-related morbidity and mortality cases and perspectives of using left ventricular ejection fraction <50% for statistical reporting

Association of medical staffing and outcomes in cardiovascular diseases

Raised life expectancy of patients with cardiovascular diseases (CVD), due to continuous progress in drug treatment options and widespread use of innovate technologies, increase the burden of CVD on healthcare system. The development of human resources by highly qualified specialists is of fundamental importance. For the rational use of human resources to achieve the targets of federal project on the prevention of cardiovascular diseases, it is necessary not only to analyze the actual situation with medical staffing, but also the potential effects of staff shortages and imbalances on mortality. The review presents evidence of associations between staffing and quality of care and CVD outcomes

Implemented models and elements for heart failure care in the regions of the Russian Federation: prospects for transformation into regional cardiovascular risk management systems

The high and growing incidence and mortality of patients with heart failure (HF) should receive priority attention when developing an action plan to reduce cardiovascular mortality in the Russian Federation. The article provides an analysis of the implemented elements of HF care in 40 Russian regions (Northwestern, North Caucasian, Volga, Southern Federal districts), some of the best practices, as well as prospects for implementation of the cardiovascular risk management system
