Published: November 2021

Metastasis is the leading driver of cancer-related death. Tumor cell plasticity associated with the epithelial–mesenchymal transition (EMT), an embryonic program also observed in carcinomas, has been proposed to explain the colonization of distant organs by the primary tumor cells. Many studies have established correlations between EMT marker expression in the primary tumor and metastasis in vivo. However, the longstanding model of EMT-transitioned cells disseminating to secondary sites is still actively debated and hybrid states are presently considered as more relevant during tumor progression and metastasis. Here, we describe an unexplored role of EMT on the tumor microenvironment by controlling tumor innervation. Using in vitro and in vivo breast tumor progression models, we demonstrate that TGFβ-mediated tumor cell EMT triggers the expression of the embryonic LincRNA Platr18 those elevated expression controls the expression of the axon guidance protein semaphorin-4F and other neuron-related molecules such as IGSF11/VSIG-3. Platr18/Sema4F axis silencing abrogates axonogenesis and attenuates metastasis. Our observations suggest that EMT-transitioned cells are also locally required in the primary tumor to support distant dissemination by promoting axonogenesis, a biological process known for its role in metastatic progression of breast cancer.
PPP Loans & State-level Employment Growth
Authors: Tasci Murat , Njinju Bezankeng , Braitsch Hana
Published: November 2021

In this Economic Commentary, we focus on the first round of Paycheck Protection Program (PPP) loans granted beginning in March 2020 until early August 2020, when turbulence in the labor market was pronounced, in order to demonstrate the PPP’s effects on local labor markets. We find that PPP loans helped mitigate the negative impact of the pandemic recession on state-level employment growth. States that received most of their funding early in the loan period had smaller employment declines than did states that received comparable funds later in the period.
Promoting Collaborative Pedagogy in Classrooms: Challenges and Solutions
Authors: Omodan Bunmi Isaiah
Published: November 2021

Collaborative pedagogy appears to be productive among students and thereby adopted in many classrooms to ensure that students are active participants in the knowledge production process. However, challenges exist among students, alongside their instructors, which hinders the active involvement of students in the collaborative knowledge production process. In the same vein, the study also examines the possible ways to navigate the challenges. The argument is located within social constructivism and conceptual analysis of collaborative pedagogy to explore the trajectories of collaborative classrooms in schools. In response to the challenges, the study proposed solutions that include promotion of unity in diversities among students, the introduction of cultural variations in classrooms, and instigation of student’s readiness to interact. The study concludes that collaborative knowledge construction is worthy of being promoted with the recommendation that schools should ensure that students are taught to be united in the process of generating knowledge and that there must be concerted efforts to teach different cultures in the system with student motivation for natural interest.

THE „PYGMALION EFFECT“ IN THE CLASSROOM
Authors:   University „Prof Dr Asen Zlatarov”, Burgas, Dishkova Mariya
Published: November 2021

The article provides a brief literary review of some concepts, which are more characteristic for the psychological sciences, but have adequate application in pedagogical practice. This is the „Pygmalion effect“, which means that expectations of students are high, and this will lead to higher academic results on their part. This concept is related to the so-called „self-fulfilling prophecies“ – the individual develops to the extent that we expect from her/him. Of course, these phenomena are extremely important for the atmosphere in the classroom, because in a sense they determine the teacher’s attitude towards students. An attempt is made to define other terms: „Galatea effect“ and „Golem effect“ as well.

The process of development in preschool and primary school age implies the expansion of contacts with the social environment and, accordingly, the opportunities for full and diverse communication. There are new real and virtual models, in addition to parents, for imitation and identification, the process of social learning is developing in terms of attempts to model social relationships. The game-cognitive situations for stimulating prosocial behavior (behavior aimed at external observance of social norms) presented and tested in the educational process in the kindergarten are a consequence of a study of the life values and educational orientations of the modern Bulgarian family, as well as the notions of 5–7-year-old children about the needs and claims between children, teachers and parents, their ideas of good and evil, likes and dislikes of peers. They can also be realized in the system of the primary level of primary education in the classroom.

DEVELOPMENT OF SPATIAL PERCEPTIONS IN PRESCHOOL AGE THROUGH GEOMETRIC TRANSFORMATIONS IN THE APPLICATION OF A COMPETENCE APPROACH
Authors:   University „Prof Dr Asen Zlatarov”, Burgas, Dimitrova Krasimira
Published: November 2021

During preschool age a number of notions are formed related to the development of the child’s personality. Orienteering within space is part of the mathematical preparation of children in kindergarten. This section is one of the most difficult to master. A specific feature of childhood is the concrete-image thinking. To perceive the world around them, children need many examples. Preschoolers handle objects – they rotate, move, but do not analyze their actions. This paper describes the need and role of setting appropriate cognitive tasks to promote the development of spatial orientation of preschool children. The main part of the cognitive tasks related to the formation of spatial perceptions is intended to be mastered through the mathematical educations. Insufficient provision of materials and difficulty in perception by children do not motivate teachers to prefer to work in time for additional activities. It is this fact that provokes us to show that many resources can be created that are interesting for children and at the same time have great cognitive value. Practical developments about the topic are presented, which are realized in the education of students – future pedagogues. Various options are proposed, related to translation or transfer of an object, construction of objects and counting of geometric figures. The presented practical results are part of a study of the possibilities for applying a competency approach in kindergarten. In order to achieve a change in the educational system, it is necessary the University to prepare young educators for a new way of pedagogical interaction.

Published: November 2021

The article offers a brief historical overview of some of the main methods in foreign language teaching and focuses on the use of the native language in their application. A modern study conducted among children from nursery schools in Bulgaria shows that when language education is carried out only in the target language, children also use only this language in their language interactions and vice versa. Some of the research findings are that 42.2 percent of the children whose teachers communicate with them in both languages, also make use of Bulgarian when trying to convey meanings and messages in English language. In general, children’s comprehension skills are better developed than their English speaking skills. In conclusion, the research results show that at the present stage, the offered foreign language education of children in nursery schools as entertaining as it may be, is not effective enough. Working methods and well-established approaches should be applied in early foreign language education of children in order to develop their skills to communicate in a new language.

Published: November 2021

The proposed material is based on a survey conducted among second- and third-year students at „Prof. Dr Asen Zlatarov“ University, Burgas with specialties „Preschool and primary school pedagogy“, „Preschool pedagogy with a foreign language“, „Primary school pedagogy with a foreign language“ and „Social pedagogy“. The choice of these specialties is justified by the fact that these students have musical disciplines in their curriculum. The personal observations of the author and the need to check and expand and enrich the knowledge of the students (and through the information from the survey) are the reasons for the creation and implementation of the survey. The survey includes questions about some of the significant and bright representatives of the first and second generation of Bulgarian composers, based on the Bulgarian musical culture as part of the world musical heritage. The questions posed in the survey are in accordance with the musical material (song and instrumental), with which the students get acquainted during their music education. The analysis of the survey leads to conclusions concerning both the general musical culture of the students in the field of Bulgarian professional music, as well as their knowledge and gaps in this field. The development and enrichment of young people’s knowledge in the field of Bulgarian professional creative output is in the context of improving their skills for learning and expression through creativity, which leads to increasing the level of their social, civic and cultural competencies.

This article presents new trends and challenges for education – effective and necessary for the times in which we live. Today, more than ever, as professional teachers, we need to guarantee every student and parent the values of education and a calm school environment. We need new tools to meet new challenges, to stimulate and inspire our students so that they can reach their full potential, feeling confident and at ease that they are in safe hands. Diversity today is the focus of the evolutionary process of quality, which is certainly difficult, problematic, painful, and yet real. We need to apply strategies, methods that prepare pedagogical specialists to apply traditional education in a new, modern way, emphasizing the positive. It is important to skilfully develop our digital skills that will be useful in classroom work and personal development of teachers and students, worthy of every European citizen. A priority for new trends in education is positive education, building strong teachers with „soft skills“ and the opportunity to always face the challenge of flexibility, looking for non-standard solutions, changing plans, taking advantage of all opportunities in the environment, and helping. The article focuses on the possibility of building „soft skills“ in teachers and students working on a common goal – building mutual trust, discipline, perseverance, motivation, and interest in learning.

The paper presents some games to help the adult to find the right way how to help the child to recognize, understand, name, express and adequately control their emotions. The material is interesting, useful and practically applicable. The role of the teacher in the process of interaction is extremely responsible, as he/she is the authority and the child copies his/her behavior. It is important to encourage good behavior and positive behavior in children. Our work with children also covered the period of their learning in an electronic environment from a distance. The successful partnership with the families led to the realization of the goals and tasks set by the teams for the development of emotional intelligence in children. The child is a book that „reads“ the development and stability of the emotional environment in the family and the adult’s mission is to choose how to write this book.

Published: November 2021

Study of the elemental composition of the soil-grape-wine chain and correlation relationships between the chain links is presented. The objects of the study were grapes of the Muscat, Cabernet and Merlot varieties, wine samples produced from them and soils of the viticultural areas. Concentrations of Li, Mg, Al, K, Ca, V, Mn, Fe, Ni, Co, Cu, Zn, Rb, Cd, Pb, Ba, Na, Ti and Sr in soils, grapes and wines were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). Relationships between the elemental composition of the objects under study were assessed by statistical modelling using the STATISTICA software. The character of metal distribution in the soil-grape chain was studied for three forms of the element extraction from soils. We determined their gross content, the content of acid-soluble and mobile forms. The degree of absorption of mobile forms of metals by grapes was estimated using «biological absorption coefficient»., Values of the biological absorption coefficient (BAC) of different metals depend on the grape variety. High BAC values are observed for Rb, Ti, Mg, Zn, Cu, Na, Fe, Al, and Sr in Merlot grapes; K, Pbm and Ni in Muscat; and for V and Mn in Cabernet. The lowest BAC values were observed for Co, Ba, and Ca in all grape varieties under study. Each grape variety formed its own individual elemental image due to the different nature of absorption of the studied metals. The transfer of metals from grape to wine for all considered varieties was accompanied by a decrease in the concentrations of Mg, Al, K, Ca, Mn, Ni, Cu, Zn, Rb, Ba, Ti, and Sr and by an increase in the content of V, Fe, Co, Pb, and Na. Discriminant analysis revealed the metals with the highest identification properties, considering their form present in the soil. The results obtained can be used when setting markers determining the varietal and regional origin of wines.
Study of the regularities of resistance to deformation and damage accumulation under irregular low cycle loading
Authors: Gadenin M. M.
Published: November 2021

The results of computation and experimental studies of changes in the regularities of the strain resistance and damage accumulation in conditions of the irregular low cycle loading are presented and compared with similar data for a regular cyclic elastoplastic deformation at the same loading. The irregular mode of low cycle loading implemented in the study is adopted in the form of an equiprobable distribution of changes in the stress amplitudes within a given range between maximum and minimum levels at the symmetric form of the cycles. This mode was reproduced on test equipment through introduction of the corresponding functional dependence of changes in the stress amplitude in the cycles into the control program. The data on a cycle-by-cycle kinetics of both cyclic and unilaterally accumulated strains obtained under irregular mode of loading were recorded in a databank and then compared with the data for a regular loading. This provided the possibility of their analytical description by the corresponding equations of state with the correction of the parameters of the diagrams of cyclic elastoplastic deformation taking into account the conditions of irregularity of loading modes. The results of the experiments are presented in the form of diagrams of the tests modes, curves of a low cycle fatigue of the studied material at the soft and hard loading modes, diagrams of a cycle-by-cycle kinetics of the cyclic and accumulated strains at the regular and irregular modes, and also as kinetic diagrams of damages accumulation for these conditions. Using the summation criteria expressed through the deformation characteristics of accumulated damage, it is shown that taking into account change in the character of the strain development under irregular low-cycle loading, the criterion dependences can be used to assess the durability and compare it with the similar data under regular modes when accepting the condition of attaining the limiting state.

The anisotropy of the properties of a ceramic cutting insert (for three faces) obtained by the lithography-based technology from the Al2O3 + ZrO2 composite has been studied. The study was carried out using the indentation method and Mayer’s law. This method, in contrast to the bending test, excludes the sample destruction. All the studies were carried out on three faces of a ceramic cutting insert made of a composite Al2O3 + ZrO2. The behavior of the Mayer index was studied in the range of loads from 2 to 20 kg and from 0.2 to 1 kg. The results of studying the density, phase composition and microstructure of each face of the sample are presented. The study of the adhesion of the printed layers were also carried out using a Knoop indenter. No anisotropy of the hardness was observed in the load range up to 10 kg. It is shown that a layered structure present in the sample, contributes to the hardness anisotropy under the load of 20 kg and more. No anisotropy of the fracture toughness is observed in the load range of 2 – 20 kg. The results of using a Knoop indenter revealed a high adhesion between 3D printed layers. Studies using a Knoop indenter have indicated high adhesion between the layers of 3D printing.

Published: November 2021

Research 2019-2020 in the conditions of the forest-steppe zone of the Chelyabinsk region showed that the effect of glauconite on the yield and seed productivity of potatoes largely depends on the variety. The effect of glauconite (in doses from 10 to 40 t / ha) on the yield of tubers was proportional to the duration of the growing season of the varieties. The highest yield gains from glauconite were observed in the mid-ripening variety Tarasov – 4.05–4.62 t/ha, then in the medium-early variety Nevsky – 3.26–3.63 t/ha, and the smallest – were in the early variety Rosara – 1.95–2.26 t/ha. Whereas the effect of glauconite on the seed productivity of varieties had the opposite pattern: the greatest increase was observed in early-maturing varieties (Rozara – 1.30–1.56 times, Nevsky – 1.30–1.61 times), and the smallest – in the mid-season variety Tarasov (1.17–1.25 times).
