Authors: Mukhamedkhanova A. B. , Tulemetova A. S. , Zhurynov G.M.
Published: April 2021

The problems of ensuring effective management and forming competitiveness of industrial enter-prises are relevant regardless of the conditions for conducting business activities. The fact is that the competitiveness of business structures in modern conditions is not ensured by simply owning factors of production (labor, capital, land), and even entrepreneurial talent is not currently a source of obtaining stable or exclusive competitive advantages. In order to obtain sustainable or exclusive competitive advantages that constitute strategic competitiveness, the business structure needs to have an intellectual (educational) component of development, including the production and implementation of innovations, as well as readiness for changes. Subject of research. On the basis of innovative foresight, ensuring the competitiveness of business structures of the production industry is a set of organizational, managerial and economic relations that arise in the process of formation. Purpose and objectives of the study. Development of proposals to improve the competitiveness of business structures based on innovative foresight. A number of theoretical, methodological and practical issues related to the formation and implementation of a strategy for managing the innovative development of entrepreneurial structures based on innovative foresight remain insufficiently studied and require further development of rules for its creation and functioning. At the same time, despite a detailed description of the problems of strategic management of innovative deve-lopment of business structures, the research of foreign scientists was carried out in relation to the relatively stable conditions of the economy of developed countries, the practical application of the mechanisms proposed by them in the conditions of the Kazakh economy requires mandatory revision, taking into account the specifics of the modern economy and industry.
Persuasion and Mind Control in Leadership Discourse: A Socio-Cognitive Approach towards Selected Political Speeches
Authors: Masroor Farzana , Shaikh Sidra , Marwa Safa , Afzaal Saman
Published: April 2021

Political leaders frequently engage with masses to fulfil their political agenda. For this purpose, language serves as a vital tool in the hands of politicians and that is mostly noticeable in political speeches made on various public forums. Taking into account the significance of such speeches for moving the masses in their favour, the present study carries out a critical discourse analysis of politician and current Prime Minister Imran Khan’s speeches for uncovering the strategies adopted for such purposes. The researchers have chosen three speeches of the politician from three different eras, such as the protest era, pre-election era, and the post-election era. These eras have been categorized following stratified sampling technique. The lens of critical discourse analysis has been applied to the speeches using van Dijk’s (1993) socio-cognitive approach. The analysis focuses on the use of strategies such as mind control, rhetoric art, argumentative move, emotional attachment and historical distortion. The results have attributed Imran Khan’s rise to the position of Prime Minister to his strategic and manipulative political discourse in his speeches. His primary focus remained on controlling the mind of the youth which has been achieved through the use of above-mentioned strategies in multiple ways. This research is significant as it creates awareness as well as consciousness in the public regarding rhetorical strategies adopted by political leaders such as Imran Khan to exercise mind control and mould public opinion in their favour.

Compositionality of Rewriting Rules with Conditions
Authors: Behr Nicolas , Krivine Jean
Published: April 2021

We extend the notion of compositional associative rewriting as recently studied in the rule algebra framework literature to the setting of rewriting rules with conditions. Our methodology is category-theoretical in nature, where the definition of rule composition operations encodes the non-deterministic sequential concurrent application of rules in Double-Pushout (DPO) and Sesqui-Pushout (SqPO) rewriting with application conditions based upon M-adhesive categories. We uncover an intricate interplay between the category-theoretical concepts of conditions on rules and morphisms, the compositionality and compatibility of certain shift and transport constructions for conditions, and thirdly the property of associativity of the composition of rules.

Authors: Tien Huynh Thuy
Published: April 2021

Ho Chi Minh City is considered as one of the most developed economic and financial centers of Viet Nam. In addition to the achievements, the city's development has also put considerable pressure on addressing housing needs for the residents. In recent years, the demand for social housing for low-income people in developed cities has accounted for a high proportion, up to 60% of the total. Although the city government has been had many policies to encourage investers to participate in social housing projects and provide financial support for home buyers, the results are still quite limited. Currently, real estate projects are generally focused on commercial housing projects due to high profitability and fast capital recovery time; together with the house prices in urban areas are constantly increasing and many times higher than the average income of the residents. The above factors have put great pressure on urban housing development to ensure basic rights to accommodation of the people. The article summarizes the current situation of social housing development policies in Ho Chi Minh City from 2006 to present; assess achievements and shortcomings; thereby proposing solutions to help improve the effectiveness of social housing development policies in urban areas.

School-to-University Transition: The Paradox of Motivated but Undecided Students
Authors: Christodoulou Michalis
Published: April 2021

Educational research on university transitions has repeatedly highlighted that inequalities related to cultural origin still persist even though intergenerational upward mobility has been facilitated over the last fifteen years due to the huge enrollment rates documented across countries in the Western world. In contrast to this line of research in which differences between social or cultural groups are investigated, the unit of analysis in this article is a demographically homogeneous group of families in which the parents invest in university studies as the main route for their children’s post-18 pathways. Through a variable-based research design we explore the conditions which affect high-school students’ motives for following university studies. The main finding has to do with the fact that it is how late or early students make their decision that is the factor differentiating the families within this group and affecting the students’ transition to university.

TEACHERS' PERSPECTIVE ABOUT FACTORS THAT PREVENT SUCCESS IN TEACHING AND LEARNING PROCESS IN HIGHER EDUCATION OF ENGINEERING IN BRAZIL
Authors: de Almeida Mello Gláucia Nolasco
Published: April 2021

The last fifteen years, in Brazil, the number of engineering freshmen had a huge increased and, although the number of graduated also had increased over the same period, the percentage of engineering freshmen are by far higher than engineers graduated. In this context, there is a clear evidence of the high dropout rate in higher education courses of engineering in Brazil. Once most of developed researches about engineering courses dropout in Brazil are focused in the students and institutions point of view about factors that affect dropout rate, in this research it was investigated the professors perspective to answer the three questions: (1) What are the main factors which prevent success in teaching and learning process identified by professors of engineering during the classes? (2) How can professors to improve the teaching and learning process in higher education courses of engineering in Brazil? (3) How can Higher Education Institutions (HEI) support the professors? The research data were collected through team activities developed with 134 professors of higher education courses of engineering. This research reveals that the most important factors that affect negatively the teaching and learning process are related to inadequate high school preparation and behaviour of students. Main suggestions of professors for improving the teaching and learning process and also students' motivation are related to pedagogical aspects such as: use of Information and Communication Technologies (ICTs) as support of classes and implementation of professor and student support programs with significant participation of HEI.
Key words: qualitative research, problems in engineering education, professor's perspective, higher education of engineering in Brazil.
Targeting the tumor microenvironment in chronic lymphocytic leukemia
Authors: Svanberg Rebecka , Janum Sine , Patten Piers E.M. , Ramsay Alan G. , Niemann Carsten U.
Published: April 2021

The tumor microenvironment (TME) plays an essential role in the development, growth, and survival of the malignant B-cell clone in chronic lymphocytic leukemia (CLL). Within the proliferation niches of lymph nodes, bone marrow, and secondary lymphoid organs, a variety of phenotypically and functionally altered cell types, including T cells, natural killer cells, monocytes/macrophages, endothelial and mesenchymal stroma cells, provide crucial survival signals, along with CLL-cellinduced suppression of antitumor immune responses. The B-cell receptor pathway plays a pivotal role in mediating the interaction between CLL cells and the TME. However, an increasing number of additional components of the multifactorial TME are being discovered. Although the majority of therapeutic strategies employed in CLL hitherto have focused on targeting the leukemic cells, emerging evidence implies that modulation of microenvironmental cells and CLL-TME interactions by novel therapeutic agents significantly affect their clinical efficacy. Thus, improving our understanding of CLL-TME interactions and how they are affected by current therapeutic agents may improve and guide treatment strategies. Identification of novel TME interactions may also pave the road for the development of novel therapeutic strategies targeting the TME. In this review, we summarize current evidence on the effects of therapeutic agents on cells and interactions within the TME. With a growing demand for improved and personalized treatment options in CLL, this review aims at inspiring future exploration of smart drug combination strategies, translational studies, and novel therapeutic targets in clinical trials.

KHARKIV AGREEMENTS OF 2010: VISIONS OF POLITICAL, MEDIA AND EXPERT CIRCLES IN UKRAINE
Authors: ARTYMYSHYN Pavlo
Published: April 2021

The main visions of the political, media, and expert circles in Ukraine concerning the conclusion of the Kharkiv Agreements in 2010 – the pact between Ukraine and the Russian Federation on the stay of the Black Sea Fleet of the Russian Federation Navy on the territory of Ukraine are determined.

It is alleged that circles close to the President of Ukraine, Viktor Yanukovych, saw them as a sign of the beginning of an era of intense Ukrainian-Russian relations, including the issue of cheaper gas, which would help to overcome the crisis in the economy and provide a lower price for gas for both industrial and household consumers. Instead, the agreements in the opposition were seen as a betrayal of Ukrainian national interests, the creation in the Black Sea region of a destabilizing center in the form of the Black Sea Fleet of the Russian Navy, and the beginning of Ukraine’s integration into the Russian geopolitical space.

At the same time, the Ukrainian side was unable to persuade the Russian to sign new gas agreements to revise the price of «blue fuel» in essence, rather than through a discount system. Opposition criticism was also not effective under these circumstances: although the topic of prolongation of the Russian Navy’s Black Sea Fleet base in Sevastopol became one of the tenets of their anti-government rhetoric, however, the unification of the opposition had not yet grown into an institutionalized movement, acquiring such features only on the eve of the parliamentary elections in 2012. Instead, the Russian side took full advantage of the Ukrainian concessions of 2010. It is the preservation of the Black Sea Fleet on the Crimean Peninsula that allowed the Russians to prepare the ground for its annexation and for the nourishment of the Russian chauvinist ideology about Sevastopol as a «Russian city».

Keywords: Kharkiv Agreements of 2010, politicum, mass media, expert environment, visions, the Black Sea Fleet of the Russian Federation Navy, gas, Ukraine, Russian Federation.
MILITARY-POLITICAL COOPERATION BETWEEN UKRAINE AND NATO: FEATURES OF THE IMPLEMENTATION OF COOPERATION PROGRAMS (THE END OF THE 20TH – THE BEGINNING OF THE 21ST CENTURY)
Authors: POPKO Serhii
Published: April 2021

The article shows the course of Ukraine's military-political cooperation with the North Atlantic Alliance (NATO) during the 2000s. Cooperation with NATO, which was developed within the Partnership for Peace program, was part of a set of European integration measures of our country and was made to increase the interoperability of the Armed Forces of Ukraine (AFO) with NATO units. Military-political cooperation was the priority area of​​cooperation. Cooperation with NATO has positively impacted the reform and further development of the Armed Forces, security tasks compliance. The author retrospectively analyzes the characteristics of the Ukrainian state's cooperation with NATO through the prism of bilateral relations' regulatory framework. Given the geopolitical challenges facing Ukraine in the late 20th and early 21st centuries, the emphasis is placed on the North Atlantic Alliance's importance. Bilateral relations have reached a qualitatively new level after the signing of the Charter on a Distinctive Partnership between Ukraine and NATO (1997), which intensified contacts between representatives of the Alliance and Ukraine's central authorities. The priorities of the State Program of Reform and Development of the Armed Forces of Ukraine for the period up to 2005, the State Program of Cooperation of Ukraine with NATO for the period up to 2001, the State Program of Cooperation of Ukraine with NATO for 2001-2004, the Concept of Military-Technical Cooperation of Ukraine foreign states for the period up to 2010 and other significant documents concerning bilateral relations were determined. The study stressed the futility of the multi-vector policy and the need to deepen contacts with NATO in the conditions of the Russian-Ukrainian war.

ILONA ZRÍNYI, THE SYMBOL OF FREEDOM AND COURAGE
Authors: CHOTARI Juriy
Published: April 2021

The article describes the important moments of life and active political activity of one prominent female figure in the history of Transcarpathian region – Countess Ilona Zrínyi, who lived in Mukachevo in the 17th century and protected Mukachevo Castle from the Austrian invaders. The Countess' personality is also shown as a symbol of freedom and courage, which was especially emphasized during the siege of Mukachevo Castle by the Habsburgs in the second half of the 17th century (1685–1688). The article analyses eleven original letters written by Ilona Zrínyi before the siege of Mukachevo Castle. They testify to the connection between the Countess and the leadership of the Uzhanskyi and Berezhskyi counties (present-day territory of Transcarpathian region). They are stored in the Berehove Branch of the State Archives of Transcarpathian Oblast. These letters are important sources of evidence of Europe-wide history of our region. In the final part of the present article we have collected evidence based on press material and documents in the State Archives of Transcarpathian Oblast describing the so-called «Ilona-days», i.e. celebrations commemorating the personality of the great political and historical figure, Countess Ilona Zrínyi. All the official documents provide proof of the fact of how local people of Uzhanskyi and Berezhskyi counties (present-day Transcarpathia) loved and deeply respected the countess for her courage to fight for freedom against the Habsburgs, for her never-ending feeling of responsibility for her nation, and attentive care for her own motherland. During the siege of Mukachevo Castle with Ilona Zrínyi had her son, Ferenc Rákóczi II with her, who was still a child. The siege at that time taught the future leader of the liberation struggle of 1703–1711 to be courageous, and to love his motherland. Further research into sources related to Ilona Zríny’s activities may continue in the archives of Hungary and other countries as she unsuccessfully sought to form an international anti-Habsburg coalition.

Impact of Interest Rate Differential and Exchange Rate Movement on the Dynamics of Nigeria’s International Private Capital Flows
Authors: M. Karimo Tari
Published: April 2021

The study examines the impact of interest rate differential and exchange rate movement on the dynamics of Nigeria’s international private capital flows from 2010Q1 to 2019Q4. It uses the interest rate parity theory and the Markov Switching Time Varying Transition Probability Modelling approach. Findings show that interest rate differential does not explain the dynamics of aggregate capital and Foreign Direct Investment (FDI) flows, but significantly explains Foreign Portfolio Investment (FPI) flows. Also, Movement in real exchange rate is significant in explaining outflows and inflows in FPI, and inflows in FDI, but neutral to aggregate capital flows. The study concludes that deviations from interest rate parity provides opportunities for interest rate and currency arbitrage in Nigeria but using aggregate capital flows mask this evidence. The study therefore recommends that the CBN should focus on exchange rate stabilization policies, so as not only to discourage FPI reversal but to also enhance FDI inflow. This can be done by putting in place foreign reserve accretion measures to boost the ability of the CBN to defend the Naira. The new policy initiative on remittances is a right step in the right direction as it could boost external reserve.
