Published: June 2021

The article examines the value orientations of ethnophor (a representative of a certain ethnic culture and national mentality) based on a theoretical analysis of foreign and domestic research. During the epoch of digitalisation, it is impossible to leave out the problems of ethnos itself, its ethno-cultural peculiarities, socialization, national mentality, professional and career value orientations of Caucasian women. The article reveals the designation of a woman of the North Caucasus ethnic group, values, the national way of family relations. It is emphasized that the contemporary socio-economic reality makes its own adjustments during the period of digitalization despite the traditional culture and ethno standards. In the empirical part of the study, the hypothesis was tested: being the most important part of the social environment, ethnic culture despite the ethno value’s digitalization is formed due to ethnos’s historical development and along with the preservation of ethnic mentality and ethnic character of the women ethnophors, influences the value orientations including the women’s career orientation. The study involved 100 women of different nationalities of North Caucasus aged 30 to 45 years, different fields of activity: teachers, psychologists, officials, trade workers, service providers. The set of research methods included the concept “Career Anchors” by E. Schein, the principles of the diagnosis of value orientations in a career, the translation and adaptation by V.A. Chiker, V.E. Vinokurova, projective methods for determining career orientations, the principle “Value orientations” (M. Rokich), the Questionnaire of ethno value orientations (R.R. Nakochova). The results of the study confirm the hypothesis and indicate that the ethno values are a core element in the value orientation system even during the era of digitalization, which becomes apparent concerning social situation, the capability to incarnate personal goals and determines the level of intergroup acceptance and recognition of career orientations of Caucasian women.

Published: June 2021

In this work we have used psychophysiological assessments of the human brain electrical activity according to the classical neurological method for calculating the evoked potential. The experiment was designed to extraction cognitive evoked potentials. Taking into account the characteristic components, the temporal dynamics of the EEG data channels was investigated. This approach allows one to consistently assess the distribution of all components of the evoked potential on the subject's head map. Based on the results of evoked potentials processing, a statistical comparison of the components of evoked potentials in subjects of different groups by channels was carried out in accordance with the Wilcoxon test. Demonstrated for which channels the results significantly differ between the two groups of subjects. The sequence of evoked potential analysis demonstrated in the article suits for adjusting the settings of the “brain-computer” systems for a particular subject and allows to select channels used in further BCI training efficiently.
Features of virtual communication as a new field of communication
Authors: Morozova Yanina , Rozhnenko Oksana
Published: June 2021

The Internet has brought into our life previously non-existent ways of communication and new forms of language existence. With the growing popularity of social networks, the functioning of the English language has attracted the interest of many linguists. Modernization of the linguistic personality takes place in conjunction with the development of a virtual picture of the world, which reproduces life in the vastness of the Internet. Values replace each other. If earlier language education was popular, today it is computer education. That is why a tendency has arisen to explain in a simplified language, which contradicts the norms of traditional communication. Moreover, the leading role in virtual communication belongs to the English language, since the birthplace of the Internet and the main supplier of network terminology is English-speaking America.
The cryptocurrency terminology as an object for metalanguage reflection of Russian and English speakers
Authors: Kudashina Valentina , Smirnova Nonna
Published: June 2021

The research aims to prove the assumption that the terminology of such an extraordinary socio-economic digital phenomenon as the cryptocurrency market is involved in the sphere of the Russian and English speakers’ metalanguage consciousness, and is subject to pronounced metalanguage reflection. Observation over "naive linguists" is a way to monitor lexical changes in both languages due to the emergence of the crypto market. Metalanguage reflection is understood here as the ability of an individual to reflect on the elements and patterns of language and speech: to observe the language, to notice new phenomena in it, to make generalizations, describe and explain the results of the observations. It has been shown that at present, both Russian and English speakers feel the need for clarification of the new terms and explicitly express this need. Analysis of the discourse on the Internet reveals a huge number of metalanguage comments in both Russian- and English-speaking segments of the Internet. A high degree of metaphoricity in the cryptocurrency language is noted. Another manifestation of metalanguage reflection is amateur lexicography. It was also found that professional cryptocurrency market participants feel the need for terminology standardization and are making attempts to do so.
The category of animacy-inanimacy in the Russian language and the linguistic worldview
Authors: Narushevich Andrei , Bak Hadi
Published: June 2021

The main goal main goal of our study is to give a description of a segment of the linguistic worldview, which reflects the division of objects of objective reality into animate and inanimate, which underpins the grammatical category of animacy-inanimacy of nouns in Russian. Methodology. The methodological basis of is study is comprised of the combination of structural-semantic, cultural-anthropological and comparative methods. The interpretation of linguistic phenomena is based upon the link between the grammatical form and its semantic content. The employment of cultural-anthropological approach allows us to reveal the reflection of fragments of the linguistic worldview in language forms, a reflection of collective ideas about the surrounding reality fixed in the language and obligatory for all speakers of this language. An analysis of everyday ideas about various objects of reality that are interpreted as living or inanimate, allows us to discover, at the epistemological level, several intermediate conceptual forms (interpreted as resembling the animate, as formerly animate, as a set of living organisms, etc.).This makes it possible to explain the existence of nouns with fluctuating animacy-inanimacy. Results. The performed analysis leads us to the conclusion that in the linguistic consciousness of speakers, the classification of objects as animate/inanimate is carried out not onlyon the basis of the biological properties of these objects, but also basedontheir interpretationbyspeakersas active or inactive. At the same time, ourinterpretationof some objects may cause difficulties because they combine the characteristics of both “animate” and “inanimate”.
Qualitative-characterizing complicators in the semantic-syntaxic structure positive copyrinting texts
Authors: Zubkova Irina , Alahverdieva Lidia , Zhivotkova Irina , Kruglova Svetlana
Published: June 2021

The article concerns with the characteristic features of functioning of qualitatively defining "positive" adverbs-compilers in copywriting texts, which lead to a complication of semantic-syntactic structure and pragmatic content of advertising content and are expressed as the form of free distributors of sentences - determinants that serve as expressive-emotional means of author's intention. It has been determined that "attractive" qualitatively characterizing adverbs are generally considered integral component of the advertising text, which largely forms its stylistic originality. The use of original expressive techniques and various linguistic means by copywriters helps to create a "positive", figurative text, build content according to a certain structure and to form the main idea. Reference to new material, which was not the subject of special analysis, in our opinion, will allow us to obtain additional arguments in favour of qualifying qualitatively-characterizing compilators in the semantic-syntactic structure of positive copywriting texts as determinant members of a sentence.
The role of the alternative relation in cognition and the disjunctive conjunctions as a means of its verbalization
Authors: Sklyarova Natalia
Published: June 2021

The cognitive processes of the human mind are not perceived directly, the information about them can be received through the analysis of their representation in the language means. The article is devoted to the cognitive study of the English syntactic structures with the disjunctive conjunctions used in speech, in the contextual environment. The inherent meaning of alternative which these conjunctions possess is modified under the influence of the lexical-grammatical context. It makes the English syntactic structures containing these conjunctions applicable not only for the description of the situation of choice, but also for the depiction of the situations of deficient knowledge, alternation, distribution, motivation. Due to the neutralization of the inherent meaning of the conjunctions in the context the constructions which contain them can convey in English such mental operations as enumeration, approximation and addition. The analysis of English syntactic structures with the conjunctions reveals the cognitive work of the human mind. The results of the research are useful for the English language acquisition as the syntactic structures with the disjunctive conjunctions help the speaker to achieve the variety of communicative goals.

Published: June 2021

The study examines the theoretical aspects of the patriotic education of primary schoolchildren in the context of the use of information technologies, defines the meaning and functions of information technologies in the educational process of school education. The patriotic upbringing of primary school students is more than relevant, since the preservation and revival of cultural heritage begins with a small homeland (family, courtyard, school, etc.) and is a key moment in the upbringing of the modern generation. In order to study the level of patriotic education of primary school students, we conducted a survey of schoolchildren, the results of which showed: most of them have a low level of patriotic education, which is due to the lack of due attention of the state as a whole and educational institutions in particular to the issue of patriotic education of schoolchildren. Thus, the problem of patriotic education of primary schoolchildren in the context of digitalization of education has acquired new relevance in connection with new views on the quality of upbringing and education of the younger generation.

Published: June 2021

The article deals with the issues of improving the efficiency of the educational process in higher education institutions by introducing it into the educational process. The formation of the digital economy is a global trend that dates back to the late 90s of the twentieth century, when for the first time global communication networks formed the market for digital products and services. From chain stores, contactless payment systems and remote communication, the world has moved to virtual reality and the digital sector of the economy in the context of digitalization, it is the basis for subsequent decisions. The resulting concept should be gradually implemented in various types of management of an educational organization with the widest possible use of IT services. The emerging multi-user environment involves the interaction of participants in the educational process: system administrators, teachers, students, involved persons (consultants) in a single network with an accessible interface. The network nature of the organization makes it possible to ensure the self-improvement of the proposed system and bring it to the level of artificial evolution, which will avoid the need for constant modernization and the inevitable delays and errors associated with the adoption and debugging of the upgraded system. The evolutionary scenario allows to improve the system in the process of its operation without the need to change the generations of services, retrain employees, making do with minimal support and maintenance. The effectiveness of the proposed system is ensured by the modern educational motto of digital development “improvement at work”.

Computer-mediated communication in DIY discourse
Authors: Pervukhina Svetlana , Churikov Mikhail
Published: June 2021

Do-It-Yourself discourse (DIY discourse) is communication aimed at teaching laymen to do professional processes and exchanging experiences in professional spheres. It is a very called-for tool for non-vocational training. DIY discourse comprises non-verbal, verbal, and polycode texts. In this research we analyzed general characteristics of DIY discourse. On the first stage of our research we selected articles from www.wikihow.com that teach the lay audience how to do different things. On the second stage of the research we analyzed genres that occur in the computer-mediated environment and polycode texts that represent the computer-mediated communication (CMC) in the DIY discourse. From a semiotic point of view, non-verbal texts are an emblem of a professional process, verbal texts provide a symbol side, and polycode texts combine an emblem and a symbol. We have found out that DIY discourse comprises several genres with different semiotic codes. It can have non-verbal, verbal and polycode format. We have come to the conclusion that polycode texts are the specific feature of computer-mediated communication. They are widely employed in DIY discourse to achieve a more profound comprehension of the professional processes.

Methodische Untersuchung zu Mengen- und Spurenelementkonzentrationen in Pferdekotproben unter besonderer Berücksichtigung des Probenentnahmeortes
Authors: Staufenbiel Lydia , Müller Anja-Elvira , Gehlen Heidrun
Published: June 2021

Gegenstand und Ziel Eine objektive Kontrolle der Mineralstoffversorgung erfolgt bei Pferden in der Praxis nur selten, was eine fehlerhafte Supplementierung zur Folge haben kann. Durch Beurteilung der nutritiven Versorgungslage über die Kotanalyse ließe sich diese diagnostische Lücke schließen. Voraussetzung ist die Kenntnis methodischer Einflussfaktoren auf die Mineralstoffkonzentration in den Kotproben. Vor diesem Hintergrund wurden der Einfluss des Kotprobenentnahmeorts und die Art der Mineralstoffergänzung auf die Konzentration von Mengen- und Spurenelementen in Pferdekotproben evaluiert sowie der methodische Fehler der Gesamtmethode geschätzt.

Material und Methoden Untersucht wurden die Konzentrationen von 6 Mengen- und 22 Spurenelementen in 30 Kotproben von 5 Warmblütern, 3 Haflingern und 2 Ponys, deren Mineralstoffergänzung differierte (keine Supplementierung, berechnete Menge, Mineralleckmasse zur freien Aufnahme). Die an 3 Lokalisationen (kraniales Rektum, Ampulla recti, Kothaufen) gewonnenen Kotproben wurden getrocknet und mittels ICP-OES und ICP-MS analysiert. Neben der deskriptiven Beschreibung des Datensatzes wurden die Effekte der fixen Faktoren Probenentnahmeort und Mineralstoffergänzung auf die Konzentrationen der Elemente im Kot sowie die Wiederholbarkeit und der relative Fehler der Untersuchungsmethode ausgewertet.

Ergebnisse Der Entnahmeort der Kotproben hatte keinen Einfluss auf die Konzentration der einzelnen Elemente. Die Art der Mineralstoffsupplementierung spiegelte sich signifikant und differenziert in den Konzentrationen der Elemente im Kot wider. Die Wiederholbarkeit der Analyseergebnisse war mit einem mittleren Bestimmtheitsmaß von 0,949 (0,894–0,978) und einem mittleren Median für den relativen Fehler von 0,18 (0,01–0,86) hoch.

Schlussfolgerung und klinische Relevanz In der Studie werden die ersten methodischen Randbedingungen zur Bestimmung der Konzentration von Mengen- und Spurenelementen in Pferdekotproben dargestellt. Die Lokalisation der Kotprobenentnahme beeinflusste die Resultate nicht, somit könnte der am wenigsten invasiven Probengewinnung aus einem Kothaufen der Vorzug gegeben werden. Da sich die Art der Mineralstoffergänzung in signifikant unterschiedlichen Elementkonzentrationen in den Kotproben widerspiegelt, kann anhand der Kotprobenkonzentration auf eine unterschiedlich hohe Mineralstoffaufnahme geschlossen werden.
Relationship between clinical signs and hormonal analytical findings in bitches with lactatio sine graviditate
Authors: Ganz Sebastian , Olschewski Carla , Failing Klaus , Bostedt Hartwig
Published: June 2021

Objective Lactatio sine graviditate of the bitch can become clinically relevant in particularly severe manifestations. The aim of the study was to relate the hormone pattern consisting of progesterone (P4), estradiol 17β (E2) and prolactin to the time of occurrence of lactatio sine graviditate in the course of metoestrus and anoestrus as well as to its symptomatology.

Material and methods Sixty-eight bitches with apparent lactatio sine graviditate were divided into 3 groups according to their cycle status. All bitches were examined for gynaecological findings. Furhtermore, their blood progesterone, oestrogen, and prolactin concentrations were determined and compared with the 133-day hormone profile of 7 control animals.

Results Lactatio sine graviditate occurring in early metoestrus was characterised more by a shifted P4:E2 ratio than by hyperprolactinaemia. Overall, the prolactin concentration in the peripheral blood was significantly increased. Analysis of the individual cases revealed that hyperprolactinaemia was present to varying degrees. It could be detected in almost all bitches that showed full symptomatology at the end of metoestrus or at the beginning of anoestrus. Only then clinical signs correlated with an increased prolactin concentration in the peripheral blood. In most cases, the estradiol-17β concentration was within the reference range.

Conclusion and clinical relevance The study indicates that the administration of prolactin inhibitors alone is not indicated in all cases of lactatio sine graviditate and that the timepoint of onset of the clinically relevant symptoms and the current prolactin level should be taken into account in the treatment of affected bitches.

Published: June 2021

ABSTRACT Vulnerability during the coronavirus disease 2019 (COVID-19) pandemic is an emotional state that affects all of us globally. The Italian experience shows that our general practitioners (GPs) seem to have a higher rate of death due to COVID-19 infection than other physicians. This article discusses clinical ethics questions related to the vulnerability of GPs and the community during the pandemic in Italy: the total lack of, or the inadequate protection of personal protective equipment, the increased use of virtual medicine, and the value of a solid synergy between hospitals and territorial systems. We provide a few examples of experiences in other affected countries and populations (Indigenous communities in Brazil, Australia and Germany). In conclusion, we offer some reflections on the crucial role of communication in dealing with vulnerability issues during this COVID-19 pandemic period.
Access to care: a qualitative study exploring the primary care needs and experiences of older people needing assistance with daily living
Authors: Kunin Marina , Advocat Jenny , Gunatillaka Nilakshi , Russell Grant
Published: June 2021

Older people who live in the community and need assistance with daily activities are a unique group of patients to treat in the primary care (PC) setting. This study aimed to understand access-related PC needs and experiences of community-living people over 65 years of age receiving home-based assistance through the Home and Community Care (HACC) program in Melbourne, Australia. This descriptive qualitative study used thematic analysis of in-depth interviews with HACC program clients and assessment officers. Access-related needs and experiences were examined using the patient-centred access to care framework. Client (n = 11) and assessment officer (n = 4) interviews showed that community-living older people receiving home-based assistance from social services are able to find a GP according to their preferences; however, some challenges in access to comprehensive care exist. These challenges relate to regularity of PC attendance, out-of-pocket fees for specialist care and maintaining an enduring patient–GP relationship. GPs can play an important role in improving PC access for vulnerable older people. In particular, GPs can contribute to improving PC attendance and facilitating more affordable access to specialist care by improving systems to recall patients more regularly and developing explicit systems for linking vulnerable patients to affordable specialist services.

is the average nuclear spin polarization. The correction, derived by extending the Lowe–Gade theory to low-temperature cases, implies that transportation of nuclear magnetization through nuclear spin diffusion accelerates when the system is hyperpolarized, whereas for low polarization the correction factor approaches unity and the diffusion coefficient coincides with the conventional diffusion coefficient valid in the high-temperature limit. The proposed scaling of the nuclear spin diffusion coefficient can lead to observable effects in the buildup of nuclear polarization by dynamic nuclear polarization.

Authors: Fang Yayue
Published: June 2021

Regression analysis is a predictive modeling technology in big data analysis. In the field of statistics, regression analysis is an analytical method to determine the quantitative relationship between two or more variables. As one of the regression analysis methods, the multiple regression model can achieve the purpose of outcome prediction and discriminant analysis in the fields of data mining and economic forecasting. Especially in the case analysis with many influencing factors and complex conditions, the model is established from a linear perspective, and the influence of various factors on the output variables is analyzed through the weights in the obtained results. Combining multivariate analysis with principal component analysis, the main influencing factors can be screened out before correlation analysis, and the linear correlation analysis environment can be filtered to make the linear results more accurate and unsusceptible to extreme samples. This paper collects the data of national enterprise income and its related influencing factors from 2010 to 2020, and establishes a multiple regression model based on principal component analysis to study human resource management in China.

Company performance can directly reflect the operation’s status, which has always been one of the central topics. Starting from the CEO power, this paper introduced the corporate innovation strategy and ownership concentration, established the corresponding research model, and studied the relationship between them. In the model design, the company performance was taken as the dependent variable, CEO power and corporate innovation strategy and ownership concentration was taken as independent variables, then the data processing software was used to establish a regression model. Through the model test, it is found that there is a positive correlation between CEO power and corporate performance, and the corporate innovation strategy can play an intermediary role in this relationship while ownership concentration can play a moderating role. This paper further improved the relevant research of corporate performance, and had certain reference significance for the operation.
An improved moving object tracking algorithm based on CAMSHIFT

Published: June 2021

There is a problem that Camshift algorithm relies too much on color as a criterion, in order to solve it, this paper presented an improved moving object tracking algorithm which combined Kalman filter predictor with Camshift algorithm. Firstly, the object model was built by Camshift Algorithm, and the centroid coordinates of the moving objectwere extracted, then the position of the object in the next frame was predicted by using Kalman filter, and finally, the value was used as the centroid coordinates of the object searched by Camshift algorithm in the next frame, proceeding with target match. The simulation results showed that this method can effectively solve the problem of target loss caused by the similar color between the target and the back. The new algorithm can effectively reduce the tracking error accumulation in the tracking process, greatly reduce the template drift, shorten the tracking time, and can have a better practicability and real-time performance.
