The article presents the results of the study of the concept of «accessibility». It is shown that the term is used as a property and a figure of speech. In the form of a figure of speech, the concept contains the accessibility property, as well as properties and factors that affect the level of accessibility. Methodological approaches and results of field studies confirming the possibility of evaluating and describing the accessibility in terms of numeric expressions are presented. Field experiments were carried out in Rostov-on-Don and Novosibirsk with the participation of more than 90 respondents. Formalized mathematical definition of route accessibility for disabled is given as well as examples of defining the values of accessibility for certain categories of disabled people. Justification of feasibility of describing the accessibility of routes by means of level scale which excludes the drawbacks of binary system of accessibility evaluation is given. The incorrect usage of object-oriented approach for evaluating accessibility for disabled at different territories and transport systems is confirmed.

In this article approaches to search for reserves of decrease in cost of agricultural production are considered. The methods of cost calculation of dairy cattle breeding products used at the studied enter-prise are analysed, short characteristic of the standard method offered by the Ministry of Agriculture is given, and calculations of alternative options are also carried out. Today creation of accounting of a production unit is very important so that not only weight units must be considered in it, but also the quali-tative structure of products must be reflected. Definition of qualitative characteristics and technological properties by production of milk which depend on use purposes can be an example. The raw materials consumption on a unit of production and its quality and also firmness of storage depends on technologi-cal properties of milk. At calculation of prime cost taking into account qualitative characteristics for cal-culation milk in terms of basic fat content undertakes. The method of calculation of prime cost consider-ing qualitative characteristics is the most expedient as prime cost of 1 c of milk unlike the operating tech-nique is lower. In the article analytical methods of reserves calculation for decrease in prime cost taking into account various factors are proved. The revealed reserves will allow an enterprise to expand its in-vestment opportunities in the future, they will give an additional incentive of modernization of the worn-out machinery and equipment in branches of agriculture.

Outbreaks of the Nearctic leafhopper Erasmoneura vulnerata represent a threat to vinegrowers in Southern Europe, in particular in North-eastern Italy. The pest outbreaks are frequent in organic vineyards because insecticides labeled for organic viticulture show limited effectiveness towards leafhoppers. On the other hand, the naturally occurring predators and parasitoids of E. vulnerata in vineyards are often not able to keep leafhopper densities at acceptable levels for vine-growers. In this study, we evaluated the potential of two generalist, commercially available predators, Chrysoperla carnea and Orius majusculus, in suppressing E. vulnerata. Laboratory and semi-field experiments were carried out to evaluate both species’ predation capacity on E. vulnerata nymphs. The experiments were conducted on grapevine leaves inside Petri dishes (laboratory) and on potted and caged grapevines (semi-field); in both experiments, the leaves or potted plants were infested with E. vulnerata nymphs prior to predator releases. Both predator species exhibited a remarkable voracity and significantly reduced leafhopper densities in laboratory and semi-field experiments. Therefore, field studies were carried out over two growing seasons in two vineyards. We released 4 O. majusculus adults and 30 C. carnea larvae per m2 of canopy. Predator releases in vineyards reduced leafhopper densities by about 30% compared to the control plots. Results obtained in this study showed that the two predators have a potential to suppress the pest density, but more research is required to define appropriate predator–prey release ratios and release timing. Studies on intraguild interactions and competition with naturally occurring predators are also suggested.

AbstractIn this paper I shall examine the use and misuse of some astronomical terminology as it is commonly found in the literature. The incorrect usage of common terms, and sometimes the terms themselves, can lead to confusion by the reader and may well indicate misconceptions by the authors. A basic definition of the Be phenomena is suggested and other stellar characteristics whose interpretation may change when used for non-spherical stars, is discussed. Special attention is paid to a number of terms whose semantic nature is misleading when applied to the phenomena they are intended to represent. The use of model-dependent terms is discussed and some comments are offered which are intended to improve the clarity of communication within the subject.


The article attempts to comprehend the essence and possibility of forming discourse competence among foreign and Russian students with simultaneous immersion in patriotic discourse. It is highlighted that the addition of the humanitarian series of “History of Civilizations” and “Features of Russian Civilization” to the educational process at the university creates the necessary pedagogical conditions for organizing a special linguo-ethno-cultural environment that forms active social interaction of authors within the framework of the medical and patriotic linguistic scenario. The authors of the article conducted a semantic and historical analysis of interpretations of the concept of “patriotism” that were studied from the point of view of traditional and liberal culture. The article presents the results of a socio-pedagogical study of students' perceptions of this concept. The article describes various theoretical and methodological approaches to the definition of the concepts of “discourse” and “discursive picture of the world” as well as psycholinguistic features of the method of semantic differential. Special attention in the article is paid to the typologies of discourse presented in the scientific literature. The authors of the article present the principle of genre and the principle of thematic correlation as the basis for distinguishing between types of discourse and highlight differences in language and discursive pictures of the world. The tasks of educators is to form not only purely medical discursive competence, but also to immerse the listener in “correctly” interpreted picture, saturated with verbal patterns that allow to create statements of patriotic content.

The article focuses on the importance of information culture as an integral part of professional culture of engineers, which affects the quality and safety of engineering solutions. The main two approaches to the definition of "information culture" are determined, which include an information approach when the information culture is reduced to the concept of computer or information literacy and a culturological approach when the concept "information culture" is seen as a way of human life in the information society. Development of the information culture acts as a process of harmonization of the inner world of man in the acquisition of socially significant information. The main components of information culture of engineers are highlighted, including literacy and competence in understanding the nature of information processes and relationships, humanistically oriented information value-semantic sphere, developed information reflection, creativity in information behaviour and socio-information activity. Based on a broad understanding of information culture as a qualitative characteristic of the life of a specialist in terms of receiving, transmitting, storing and using information, where universal moral values are the main priority, basic methodological approaches to forming information culture of future engineers are proposed, namely: system, personal, activity, integrative, culturological, axiological and reflexive approaches. The process of developing future engineers’ information culture in the process of professional training in higher educational institutions will be effective providing that it is based on the substantiated methodological approaches.

Abstract The large-scale adoption of occupational exoskeletons (OEs) will only happen if clear evidence of effectiveness of the devices is available. Performing product-specific field validation studies would allow the stakeholders and decision-makers (e.g., employers, ergonomists, health, and safety departments) to assess OEs’ effectiveness in their specific work contexts and with experienced workers, who could further provide useful insights on practical issues related to exoskeleton daily use. This paper reviews present-day scientific methods for assessing the effectiveness of OEs in laboratory and field studies, and presents the vision of the authors on a roadmap that could lead to large-scale adoption of this technology. The analysis of the state-of-the-art shows methodological differences between laboratory and field studies. While the former are more extensively reported in scientific papers, they exhibit limited generalizability of the findings to real-world scenarios. On the contrary, field studies are limited in sample sizes and frequently focused only on subjective metrics. We propose a roadmap to promote large-scale knowledge-based adoption of OEs. It details that the analysis of the costs and benefits of this technology should be communicated to all stakeholders to facilitate informed decision making, so that each stakeholder can develop their specific role regarding this innovation. Large-scale field studies can help identify and monitor the possible side-effects related to exoskeleton use in real work situations, as well as provide a comprehensive scientific knowledge base to support the revision of ergonomics risk-assessment methods, safety standards and regulations, and the definition of guidelines and practices for the selection and use of OEs.

The purpose of the article is to attempt to discover the conceptual basis of modern tourism, in particular, to justify scientific approaches. The basis of the method of work was the use of conventional methods: theoretical analysis of scientific sources on the specified topic, synthesis, description and comparison. The results are the separation of the following scientific approaches: axiological, cultural, multicultural, holistic, structural, functional, informational, synergistic, predictive, unity of quality and quantity, co-evolutionary (development), causality. The scientific novelty of the study was the interpretation of general methodological approaches in the field of tourism studies, a clear definition of their characteristics, which will help to improve its methodological basis. The practical significance of the article is to justify the expediency of using scientific approaches, which will make it possible to combine the efforts of tourism professionals under the current conditions of fundamental incompleteness and uncertainty of information on the methodology of tourism; in developing approaches that are, to some extent, capable of ensuring the effective interaction and synthesis of different science methods on a single conceptual basis.

Previous field experiments have found that artificial surveillance cues facilitated prosocial behaviors such as charitable donations and littering. Several previous field studies found that the artificial surveillance cue effect was stronger when few individuals were in the vicinity; however, others reported that the effect was stronger in large groups of people. Here, we report the results of a field study examining the effect of an artificial surveillance cue (stylized eyes) on charitable giving. Three collection boxes were placed in different locations around an izakaya (a Japanese-style tavern) for 84 days. The amount donated was counted each experimental day, and the izakaya staff provided the number of patrons who visited each day. We found that the effect of the stylized eyes was more salient when fewer patrons were in the izakaya. Our findings suggest that the effect of the artificial surveillance cue is similar to that of “real” cues and that the effect on charitable giving may weaken when people habituate to being watched by “real” eyes.

The article deals with some issues of the development of creative abilities of younger schoolchildren. It is based on the definition of essence (diagnostics, historical aspects, developmental problems), type (creative, mathematical, artistic, artistic talent, sports, musical, academic, etc. д.). From a number of philosophical analyses we conclude that the natural traits and natural abilities of people were created by a powerful god. The article analyzes the psychological and pedagogical aspects of creative endowment and offers a content analysis of the concepts of endowment and creative endowment in the works of researchers. The functions of system approach, interdisciplinary approach, individual approach, synergetic approach, reflexive approach to methodological significance of development of creative individuality of young pupils are revealed. Depending on the essence of methodological approaches, the article analyses the main methodological principles. These include: the principle of support and aspiration, the principle of subjectivity, the principle of creativity and success. This article analyses the process of diagnosing creative talent. A total of 129 students took part in the diagnostics. Diagnostic work was carried out according to A.I. Savenkov's methods "Map of interests of junior grade" (for parents and children), "Description of a pupil" (for teachers in order to systematize ideas about the development of gifted children), the technique of general assessment of talent (for parents and teachers), "Talent map" (for parents). The results of its statistical analysis are presented.

Developing new crops adapted to arid conditions is a promising approach to meet the increasing demand for food production under expanding aridity. Tef [Eragrostis tef (Zucc.) Trotter] is a C4 cereal crop cultivated mainly in Ethiopia and the Horn of Africa, and known for its high resilience to stressful environments. Due to their tiny size, tef seeds are traditionally sown by broadcasting and lightly covering with soil. Under semiarid Mediterranean conditions, a deeper sowing may guarantee seedling establishment while saving on irrigation water. The objective of this study was, therefore, to determine the effects of sowing depth on tef emergence, development, lodging, and productivity. Tef seeds were sown at different depths in test tubes and pots, and in two field experiments. In tubes and pots, time from sowing to emergence increased about twofold and emergence rate decreased in the deepest sowing (3 cm) treatment compared to controls (0 cm). In the pot and field trials, deep sowing (3 cm) significantly reduced plant height, shoot and root biomass, and lodging. Sowing depths of 1–2 cm allowed successful plant establishment while not exacting penalties on plant emergence or development; hence this range appears to be optimal for sowing irrigated tef.
