The purpose of this study is to introduce a new type of extended metric space, i.e., the rectangular quasi-partial b-metric space, which means a relaxation of the symmetry requirement of metric spaces, by including a real number s in the definition of the rectangular metric space defined by Branciari. Here, we obtain a fixed point theorem for interpolative Rus–Reich–Ćirić contraction mappings in the realm of rectangular quasi-partial b-metric spaces. Furthermore, an example is also illustrated to present the applicability of our result.

The article analyzes the cognitive signs of the macroconcept universe in Russian linguoculture. The relevance of the research is determined by the prospect of studying a new type of mental structures - symbolic macroconcepts. The purpose of the article is to describe the specifics of the macroconcept universe structure formation from the standpoint of the definition of syncretic primordial signs. The main methods in the work are the historical and etymological analysis of the studied macroconcept representative, descriptive and interpretive methods. During the study, seven motivating signs of the macroconcept universe were noted: 'earth', 'live', ‘world’,‘inhabit’,‘inhabited’,‘settlement’,‘light’. All identified motivating signs are syncretic symbolic primordial signs 'house' (conceptum, according to V. V. Kolesov). Motivating signs express two main symbolic meanings of Russian linguoculture: home is a place where people live, settle; home is the world of people and all living beings, this world-light (unlike that world-light where the souls of the dead go: that world-light is located in the sky), it is built on earth. The macroconcept universe is objectified by erased metaphors of a closed space (in particular, the metaphor of a key), which has an internal volume, center-middle, limits, parts, edges, corners, people live in this house, they live and exist in it, it is inhabited and settle down in Russian linguoculture. The model of the universe in the Russian language picture of the world is three-parted: the middle part in it represents the human world, in which the principle of anthropocentrism is manifested - a person measures space and chooses himself as a reference point. The syncretic primary sign ‘house’ unites in itself all the motivating signs of the studied macroconcept, keeping their relevance to our days. Keywords: macroconcept, motivating signs, first sign, language picture of the world, linguoculture, comparative studies

The article highlights the theoretical approaches to the definition of the concepts of small and medium-sized businesses. The relevance of the research is determined by the need to solve the problem of the development of small and medium-sized businesses in the agricultural sector in the context of digital transformation, the development and justification of directions for improving its development. The scientific novelty of the study is the formation of a complex for assessing the development of small forms of agricultural production, which allows us to develop priority strategic directions of development, including aspects of modernization of agricultural production and innovative development. The indicators of the development of small and medium-sized businesses in the agricultural sector are studied. A new type of classification feature of small and medium-sized businesses in the agricultural sector is proposed.

The article is devoted to the consideration of such an object of interdisciplinary research as the elite, namely, the latest trends in its study. It is shown that the consideration of this phenomenon has been going on for a long time, but now there is a sharp change in the focus of research – a new methodology is being developed. This is due to the fact that the axiom taken is the provision of a significant influence of the elite not only on the distribution of resources (economic, political, administrative) but also on the development (or recession) of the nation as a whole. The article presents a detailed analysis of the methodology for measuring the elite quality index which formed the basis for an international study conducted in 2020.

A 16-year-old man sustained a minor penetrating injury to his forearm, resulting in pseudoaneurysm formation that caused acute compartment syndrome with muscle contracture. Surgical treatment, including fasciotomy, evacuation of the hematoma and aneurysmectomy, followed by intensive hand therapy provided a successful outcome. Traumatic pseudoaneurysm after penetrating injury is a rare cause of acute forearm compartment syndrome. Although minor penetrating injuries tend to be underestimated, this type of injury can cause subsequent serious pathological conditions.

In this article, the motives for voluntary work and work values in higher education contexts are examined in a cross-border region in Central Eastern Europe. Our goal is to find out what kind of relationship exists between different types of volunteering and work values among young people. In the theoretical section, we deal with the definition of volunteering in the education system, the types of and motives for students’ volunteering, and finally, the relationship between the work values and voluntary work of students. In the empirical section, we created cluster groups based on students’ motives for volunteering, and we examined differences among countries. Then we revealed the factor structure of the work values of students and analyzed the relationship between cluster groups and factors with variance analysis. Five cluster groups were identified: “careerists with postmodern features,” “unmotivated,” “highly motivated,” “volunteers in an anti-volunteering climate,” and a “helping new type volunteers” group. There were only slight differences among countries, as most respondents are characterized by mixed motivations. An interesting result is that the most frequent group is “the volunteers in an anti-volunteering climate” in all the countries examined, especially in Ukraine, so the culture of volunteering is not popular enough in this region of Central Eastern Europe. Regarding the relationship between work values and volunteering, we have found that these two fields (work values and volunteering) are closely related.


In order to extend the use of group theoretical arguments to the problem of accidental degeneracy in quantum mechanics, a new type of constant of the motion, known as a conditional constant of the motion, is introduced. Such a quantity, instead of commuting with the Hamiltonian H for the system, satisfies the more general relation H A = A † H , where A † denotes the hermitian conjugate (adjoint) of the conditional constant of the motion A . This expression reduces, if A is hermitian, to the usual definition of a constant of the motion. Otherwise it defines a new type of invariance, and it is this which will be referred to as conditional invariance. A discussion of the difficulties arising from the lack of hermiticity of A , which is of course essential to its definition, is given. In particular it is shown, under fairly general conditions, that the process of introducing a variable parameter in the Hamiltonian enabling it to have simultaneous eigenfunctions with A , gives rise to an eigenvalue equation in this parameter with respect to which A may be chosen to be hermitian. Conditional invariance is contrasted with both dynamical and geometric invariance. It is found to be sometimes replaceable by either of the latter forms of invariance and for such, explicit conditions are given. Some applications of conditional invariance are discussed. These include a study of the crossing of potential energy curves, a new model of symmetry breaking, a possible means of calculating the exact number of bound states for certain potentials and conditions for the existence of bound states near to the continuum.

This paper focuses on the semiotic foundations of sociolinguistics. Starting from the definition of “sociolinguistics” given by the philosopher Adam Schaff, the paper examines in particular the notion of “critical sociolinguistics” as theorized by the Italian semiotician Ferruccio Rossi-Landi. The basis of the social dimension of language are to be found in what Rossi-Landi calls “social reproduction” which regards both verbal and non-verbal signs. Saussure’s notion of langue can be considered in this way, with reference not only to his Course of General Linguistics, but also to his Harvard Manuscripts.The paper goes on trying also to understand Roland Barthes’s provocative definition of semiology as a part of linguistics (and not vice-versa) as well as developing the notion of communication-production in this perspective. Some articles of Roman Jakobson of the sixties allow us to reflect in a manner which we now call “socio-semiotic” on the processes of transformation of the “organic” signs into signs of a new type, which articulate the relationship between organic and instrumental. In this sense, socio-linguistics is intended as being sociosemiotics, without prejudice to the fact that the reference area must be human, since semiotics also has the prerogative of referring to the world of non-human vital signs.Socio-linguistics as socio-semiotics assumes the role of a “frontier” science, in the dual sense that it is not only on the border between science of language and the anthropological and social sciences, but also that it can be constructed in a movement of continual “crossing frontiers” and of “contamination” between languages and disciplinary environments.
