A network analysis of cross-border mergers and acquisitions in Poland, Czechia and Hungary
Authors: Brózda-Wilamek Dominika 
Published: January 2022

Background: Cross-border mergers and acquisitions (CBM&As) have taken the form of a network, as there are complex business relationships between the participating entities. The concept of social network analysis (SNA) to study business connections is poorly described in the literature. There is also a lack of comprehensive structure studies on CBM&A purchases by Central and Eastern Europe (CEE) companies.
Research purpose: The purpose is to evaluate the geographical and sectoral structure of the Polish, Czech, and Hungarian CBM&A network in 2010–2020. This article also aims to present a new methodological approach to studying the structure of the M&A market related to the application of SNA metrics.
Methods: The study is carried out using social network analysis. Sectoral M&A data taken from the Eikon Refinitiv database are used, and several network indicators are applied, i.e., degree, prestige, and betweenness centrality, for the analysis.
Conclusions: In 2010–2020, Polish, Czech, and Hungarian companies were characterized by investment activity not only in the CEE countries, but also in Western Europe, Russia, and the United States. Enterprises from the financials, industrials, consumer cyclicals, and technology sectors have played an important role in CBM&A networks. Entities operating in the energy and healthcare sectors (in Hungary) and the real estate and utilities sectors (in Czechia) have also occupied a central place in the analyzed networks. Private equity and hedge funds play a key role in cross-sectoral transactions.
The Necessary Condition for Optimal Boundary Control Problems for Triple Elliptic Partial Differential Equations
Authors: A. Ali Al-Hawasy Jamil , A. Thyab Al-Ajeeli Nabeel 
Published: January 2022

In this work, we prove that the triple linear partial differential equations (PDEs) of elliptic type (TLEPDEs) with a given classical continuous boundary control vector (CCBCVr) has a unique "state" solution vector (SSV) by utilizing the Galerkin's method (GME). Also, we prove the existence of a classical continuous boundary optimal control vector (CCBOCVr) ruled by the TLEPDEs. We study the existence solution for the triple adjoint equations (TAJEs) related with the triple state equations (TSEs). The FrÃ©chet derivative (FDe) for the objective function is derived. At the end we prove the necessary "conditions" theorem (NCTh) for optimality for the problem.

Published: January 2022

Purpose: Separation anxiety is a state of extreme anxiety, felt by an individual in case of separation from attachment figure. It was aimed to investigate attachment styles, temperament traits, childhood trauma and dissociative experiences of university students diagnosed with adult separation anxiety disorder (ASAD).
Methods: Sixty five university students, diagnosed to have ASAD by a structured clinical interview were compared with healthy students via˝Adult Attachment Style Questionnaire (AAQ)," "Childhood Trauma Questionnaire (CTQ)," "Temperament Evaluation of Memphis, Pisa, Paris and San Diego Auto-questionnaire (TEMPS-A)," and "Dissociative Experiences Scale (DES)."
Results: Twenty two (33.8%) students with ASAD had problems with orientation and getting used to university. According to AAQ, students with ASAD had higher prevalence of insecure attachment styles, and especially high ambivalent attachment styles and to CTQ, students with ASAD had significantly higher scores in all subscales except physical abuse. Overall DES score was higher in students with ASAD compared to the control group. DES score and history of physical disease in the family were independent associates of ASAD.
Conclusion: DES score and history of physical disease in the family were independent associates of ASAD among university students. Hence, early awareness of dissociative symptoms and family history might help early identify students with ASAD.

Published: January 2022

Objective — to study the effect of the levothyroxine (LT) use in patients with autoimmune thyroiditis (AIT) on the course of heart failure (HF).
Materials and methods. The study included 218 patients with HF on the background of post‑infarction cardiosclerosis. 109 (50.0 %) patients with AIT received LT due to hypothyreosis in past. These patients intake LT during 2 years before included in the study and have euthyreosis. Whether the levels of TSH, T3f, T4f, T3r were determined. Echocardioscopy and ultrasound examination of the thyroid gland were conducted. We studied the course of heart failure for 2 years.
Results. Patients who used LT, comparing with patients without this drug, had smaller dimensions (EDD and ESD) and volumes (ESV and EDV) of left ventricle (LV) and 22.9 % greater LV ejection fraction (EF) (p = 0.0001), as well as higher low serum NT‑proBNP level (26.3 %, p = 0.009). In the subgroup of patients taking LT at a dose of 0.1 to 0.69 mcg/kg, LVEF did not differ from patients without this tritment. At a dose of 0.7 — 1.19 mcg/kg, LVEF is higher compared with that of patients who did not take LT (by 37.9 %) and patients who took LT at a dose 0.1 — 0.33 mcg/kg (36.9 %). LVEF was the highest in patients taking LT at a dose of > 1.20 mcg/kg. The use of LT for 2 years reduces the risk of re‑hospitalization (RH) due to decompensation of heart failure (Odds ratio = 0.490 (0.281 — 0.857), p = 0.018). The ROC analysis showed that the risk of RH in patients with heart failure due to decompensation of the disease decreases with the use of LT at a dose of > 0.53 mcg/kg (sensitivity — 56.62 %, specificity — 60.98 %, p = 0.016).
Conclusions. The use of LT in patients has a dose‑dependent positive effect on LVEF. The largest LVEF is observed in patients taking the drug at a dose of > 1.2 mcg/kg. The use of an LT dose of > 0.53 mcg/kg leads to a significant decrease in the frequency of re‑hospitalization due to decompensation of heart failure during 2 years.

У статті представлено результати теоретико-прикладного дослідження особливостей впливу спортивної діяльності на формування моральної сфери студентів педагогічного університету: діагностовано рівень розуміння сутності категорії «моральності» та змісту моральних норм і професійно важливих для вчителя якостей особистості, визначено особливості ставлення досліджуваних до моральних норм, вивчено прояви моральності і дотримання морально-етичних правил у поведінці і вчинках, проаналізовано рівень сформованості моральної поведінки у студентів факультету фізичного виховання, майбутніх вчителів.
Було встановлено, що результатом спортивної діяльності є не тільки фізична, технічна, тактична підготовленість і спортивний результат, але і зміни, що відбуваються у духовній, морально-етичній, аксіологічній сферах особистості. У студентів 1 групи, які активно займаються спортом, показники духовно-моральної вихованості значно вищі, ніж у респондентів 2 групи, які займаються фізкультурно-спортивною діяльністю лише в рамках навчальних занять, що проводяться за освітньою програмою. Також було виявлено, що ступінь реалізації конструктивності спілкування, саморозвитку, саморегуляції дій та емоцій вище у досліджуваних студентів 1 групи, які активно займаються різними видами спорту, регулярно відвідують групи спортивного самовдосконалення, беруть участь у змаганнях. Студенти 2 групи мають прагнення до розвитку морально-культурного потенціалу, але реалізація досягнення мети значно нижча бажаного.
Отже, на основі аналізу емпіричних даних було визначено специфіку впливу спортивної діяльності на особистісний розвиток майбутнього вчителя, зокрема формування моральних якостей, визначено її суттєве значення у розвитку духовності і формуванні морально-етичної поведінки студентів, майбутніх педагогів, їх прагнення і поступу до самовдосконалення.

Published: January 2022

The article substantiates the problem of the emergence, manifestation and spread of such a modern relevant phenomenon as phubbing and FOMO in the article. It was also revealed the essence of the risks of using information technology, Internet abuse, which leads to social isolation, changes in consciousness, functional changes in the brain, depressive and obsessive disorders, inability to learn, work, think deeply, etc. The state of modern research of Internet addiction, the indicators and the forms, the psychological and physiological symptoms that are characteristic of Internet addiction are analysed.
Until now, there is no consensus among researchers on the concept and definition of Internet addiction and controversy continues over the proposed diagnostic criteria, whether it is addictive. The highest level for Internet addiction is recorded in adolescents and young people, which may also indicate the presence of psychological problems: unrealized things in the field of communication, problematic relationships in the family, difficulties with learning, from which the younger generation plunges into a more successful virtual life. The results of available researches are generalized, because of which the cognitive-behavioural model of pathological Internet use is offered as two forms of Internet addiction such as specific pathological use of the Internet and multi-purpose excessive use of the Internet. A research analysis made by researchers is presented by proving the relationship between Internet addiction with phubbing and the opportunity syndrome (FOMO). The given data which suggests that FOMO and Phubbing may have the same properties, as they are both related to improper use and dependent behaviour on smartphones. According to the authors, in the development of Phubbing and FOMO play a role in certain psychological characteristics of the individual, the study of which requires further investigation. It also emphasizes the need to solve the problem of Internet addiction by creating recommendations for its prevention and reducing the degree of dependence.

Authors: Чернікова І. Д. 
Published: January 2022

Гуманітарна культура пов'язана з пізнанням і освоєнням людиною інтелектуальних і духовних феноменів, що сприяють подальшому розвитку її як особистості і інтеграції в людське співтовариство. Гуманітарна культура особистості не є застиглим утворенням, вона формується і постійно поновлюється в певному проблемному полі людської діяльності. Гуманітарна культура входить в поняття професійної культури, забезпечуючи її гуманітарну складову так само, як професійна культура входить в поняття гуманітарної як установка людини на творчу, соціально відповідальну професійну діяльність.
У статті розглядаються питання розвитку гуманітарної культури у студентів університету технічного профілю. Виявлений гуманітарний потенціал в змісті технічної освіти, який сприяє розвитку компонентів гуманітарної культури, враховує базову систему цінностей (аксіологію) сучасних суспільних відносин як реалізацію дієвої формули душевної безпеки. Духовна безпека сучасного суспільства і гуманітарна культура особистості особливо актуальна, в зв'язку з тим, що матеріальна складова не тільки зумовлює духовну безпеку суспільства, культуру особистості, але і виступає необхідною умовою для розробки і впровадження більш високих технологій інноваційної спрямованості і актуальних наукових відкриттів. Створення сучасного високотехнологічного виробництва в епоху розвитку комп'ютерно-мережевих програм, впровадження в повсякденне життя людини елементів штучного інтелекту, інтенсивне застосування винаходів, пов'язаних з нанотехнологіями, електромобілями, біороботами, киборгами, безсумнівно, змінює соціальну структуру і суспільні відносини.
В інформаційному суспільстві в період «перезавантаження» суспільних відносин особливо актуальним стає сигма безпеки, яка представляє собою особистість, що володіє, сучасними професійними знаннями, почуттям обов'язку, високим рівнем інтелекту самосвідомості, толерантністю, яка прагне до гармонії з природою і соціумом, де існує повага до загальноприйнятих норм поведінки, законам.
Chick Flick Fantasy and Postfeminism in Chinese Cinema: 20 Once Again as a Transnational Remake
Authors: Chung Elaine 
Published: January 2022

This chapter analyses chick flick fantasy as an emerging film genre in mainland Chinese cinema. It borrows the Hollywood-derived framework to read this hybridised genre with the concept of postfeminism. After surveying the rise of the chick flick fantasy in multiple Chinese media platforms, this chapter explores how the socio-cultural meanings of the global genre evolve when it travels across national borders to mainland China. From an inter-Asian perspective, it studies the case of 20 Once Again (2015), the Chinese remake of the South Korean film Miss Granny (2014), which together constitute also one of the best-selling Chinese-Korean films. It examines how the two versions, telling the same story, characterise their female protagonists with fantastical devices and generate distinctive gender discourses.

Capsule and capsule contracture around implants are important concerns in a clinic. The physical topology of the material surface regulates the formation of the capsule, but the specific regulatory mechanism is unclear. In this study, four types of silicone implant materials with different microgroove structures (groove depths of 10 and 50 μm and widths of 50 and 200 μm) were constructed using lithography to form different gradient surface topologies. Mass spectrometry, Cell Counting Kit-8, 5-ethynyl-2′-deoxycytidine (EdU), enzyme-linked immunosorbent assay, western blot, immunofluorescence, and immunohistochemistry were used to explore the changes in protein adsorption, cell adhesion, cell proliferation, and collagen deposition on the surface of the materials. At the same time, RNA-seq was used to detect transcriptome differences caused by different structures. Furthermore, collagen deposition and capsule formation were observed in the rats. The groove structure was observed to significantly increase the surface roughness of the material. The deeper groove and the narrower width of the polydimethylsiloxane would increase the surface roughness of the material and the surface water contact angle but reduce the total amount of adsorbed protein in the first two hours. In vitro cell experiments revealed that microtopology affected cell proliferation and adhesion and regulated collagen secretion. Further analysis indicated the deeper and narrower groove (group 50–50) on the surface of the material caused more evident collagen deposition around the material, forming a thicker envelope. Surface roughness of the material was thus related to collagen deposition and envelope thickness. The thickness of the envelope tissue around smooth materials does not exceed that of the materials with surface roughness. In conclusion, the narrower and deeper grooves in the micron range exhibited poor histocompatibility and led to formation of thicker envelopes around the materials. The appropriate grooves can reduce envelope thickness.

Published: January 2022

BackgroundAcinetobacter baumannii is a leading cause of healthcare-associated infections worldwide, due to both its persistence in the hospital setting and ability to acquire high levels of antibiotic resistance. Carbapenem-resistant A. baumannii isolates (CRAB) limit the activity of current antimicrobial regimens and new alternatives or adjuncts to traditional antibiotics are urgently needed. Durlobactam is a novel broad-spectrum inhibitor of serine-type β-lactamases that restores sulbactam (SUL) activity against A. baumannii. The sulbactam-durlobactam (SD) combination has recently completed Phase 3 testing in the global ATTACK trial.ObjectivesThe aim of this study is to evaluate the in vitro activity of SD versus comparators against a representative nationwide collection of CRAB isolates.MethodsOne hundred ninety CRAB isolates were collected from clinical samples of patients hospitalized in 11 hospitals throughout Greece during 2015. In vitro activities of SD and comparators (SUL alone, amikacin, minocycline, imipenem, meropenem, colistin, SD and imipenem combined with SD) were determined by broth microdilution.ResultsDurlobactam restored sulbactam activity against the majority of the strains tested, with SD exhibiting the lowest MIC90 (8 μg/ml) relative to the other single comparators tested; 87.9% of the isolates had SD MICs ≤4/4 µg/ml. The most active comparator was colistin (MIC90 = 16 μg/ml). The addition of imipenem further lowered the MIC90 of SD by one two-fold dilution.ConclusionsThis study demonstrated the potential utility of SD for the treatment of infections caused by A. baumannii. If its clinical efficacy is confirmed, SD may be an important therapeutic option for CRAB infections.

BackgroundThis study investigated whether left ventricular (LV) global longitudinal strain (LV-GLS), as an LV function parameter less affected by mitral valve (MV) repair or prosthesis, is associated with clinical outcomes in patients with surgically treated MV disease.MethodsAmong 750 patients who underwent MV surgery, we assessed LV-GLS by speckle tracking echocardiography in 344 patients (148 men, mean age 58 ± 13 years) who showed preserved LV ejection fraction on echocardiography between 6 months and 2 years after MV surgery and who did not undergo aortic valve surgery. The assessed clinical events included admission for worsening of heart failure and cardiac death.ResultsDuring a period of 42.4 ± 26.0 months, 32 (9.3%) patients were hospitalized for worsening heart failure, and 3 (0.8%) died due to cardiac causes. The absolute value of LV-GLS (|LV-GLS|) was significantly lower in patients with clinical events than in those without (12.1 ± 3.1 vs. 15.0 ± 3.2%, p &lt; 0.001) despite comparable LV ejection fraction between groups. |LV-GLS| showed predictive value for clinical events (cut-off 13.9%, area under the curve 0.744, p &lt; 0.001). Patients with |LV-GLS| ≤14.0% had poorer outcomes than those with |LV-GLS| &gt;14.0% (log-rank p &lt; 0.001). Prognosis was worse in patients with |LV-GLS| ≤14.0% and pulmonary hypertension than among those who with |LV-GLS| ≤14.0% without pulmonary hypertension (log rank p &lt; 0.001). In nested Cox proportional hazard regression models, reduced |LV-GLS| was independently associated with the occurrence of clinical events.ConclusionsIn patients with surgically treated MV and preserved LV ejection fraction, assessment of LV-GLS provides functional information associated with cardiovascular outcomes.
Oilseed Cover Crops for Sustainable Aviation Fuels Production and Reduction in Greenhouse Gas Emissions Through Land Use Savings

Published: January 2022

Induced Land Use Changes (ILUCs) can decrease the environmental benefits of Sustainable Aviation Fuels (SAFs) if produced from traditional food crops. The development of oilseed cover crops can eliminate the side effect of ILUCs for biofuel production because they come in rotation with the major crops with some savings in demand for new cropland. This study implemented Life Cycle Analysis (LCA) and GTAP-BIO to estimate ILUC emissions values, the potentially available area, and total possible emissions savings of producing SAFs from carinata, camelina, and pennycress in the United States. The results suggest that: 1) the meals produced in conjunction with increases in Sustainable Aviation Fuel production from carinata, camelina, and pennycress could reduce land use emissions by 12.9, 15.3, and 18.3 gCO2e/MJ, respectively; 2) the total area of available land for producing these feedstocks could be about 29.3 million ha in 2035; and 3) using this area of land for SAF production, depends on the mix of oilseed cover crops that can be produced in practice, could generate up to 92 million metric tons of savings in GHG emissions per year. The projected emissions savings is about 11% of the current global GHG emissions generated by the aviation industry. Providing incentives to encourage farmers to produce these cover crops and facilitating investment in producing SAF from these cover crops are the most important factors that could help the aviation industry to enhance emissions savings.

Published: January 2022

At present, 48 V mild hybrid battery systems are widely used in hybrid electric vehicles to reduce fuel consumption and emissions. The battery pack often operates at high discharge/charge rates and requires an efficient and compact battery thermal management system (BTMS) to control its temperature, improve its electrical performance and extend its life. Due to their short start-up times and simple structures, semiconductors can provide rapid refrigeration and cool a battery quickly in response to sudden high current rates. Therefore, semiconductors were applied to the BTMS of a 48 V battery. The performance of the semiconductor-based BTMS was studied by simulation and experiment at high discharge rates (up to 9.375 C). Firstly, a thermal model of the BTMS was developed that integrates a resistance-based battery thermal model, a semiconductor thermal model and a three-dimensional fluid-solid coupled heat transfer model. Unlike a traditional thermal model, the proposed model considers the joint influences of SOC, temperature and current on battery resistance and improves the predictive precision of the battery’s thermal behaviour. The thermal model was verified by an experiment, with the results showing that it could precisely describe the temperature increase in the battery (maximum average absolute error within 0.9°C). Finally, the BTMS thermal model was applied to predict the cooling performance of the semiconductor BTMS at an ambient temperature of 37°C and high current rates (up to 9.375 C), which was compared with that of an air-cooled BTMS. The results demonstrate that the semiconductor-based BTMS achieves lower battery temperature than the air-cooled BTMS and ensures a temperature difference within the 48 V pack of &lt;1.6°C.
