Аналітична філософія історії Артура Данто: парадокси історичного знання.
Authors: Мішалова Олена
Published: December 2022

Анотація: В даній роботі стверджується, що концепція аналітичної філософії історії Артура Данто є першою послідовною систематичною спробою аналітичного аналізу процесу історичного пізнання, визначення меж та можливостей пізнання минулого. Автор підкреслює, що Данто презентує постпозитивістський підхід до вирішення епістемологічних питань історії, тому його філософію історії можна вважати результатом вдалого подолання вузького позитивістського розуміння науки.
В своїй праці Аналітична філософія історії Данто чітко поділяє філософію історії на субстантивну філософію історії, спрямовану на опис “всієї історії”: всього минулого та всього майбутнього, та аналітичну філософію історії, предметом вивчення якої виступають питання історичного пізнання. Концепції субстантивної філософії історії претендують на статус теорій історії, вони часто використовують історичні дослідження як просто фактичний матеріал для своїх умоглядних побудов. Субстантивна філософія історії піддається глибокій критиці з боку Данто як помилковий спосіб мислення про минуле, що невиправдано екстраполює оповідні структури історичної розповіді у майбутнє і передбачає та оповідає про події ще до того, як вони трапилися. Історик може робити передбачення стосовно тих чи інших подій у минулому і в результаті відкрити їх, якщо його передбачення були вірними, однак історія має справу лише з минулим.
Наголошується, що Данто вирізняє й аналізує ряд «парадоксів» історичного пізнання, спричинених як малою обізнаністю істориків з тенденціями розвитку сучасної науки, так і відсутність розуміння реальних проблем історичного пізнання у сучасній філософії науки. Наприклад, це стосується питання опосередкованості предмету вивчення, що скоріше є правилом, аніж виключенням для сучасних наук, тому не становить перед історією якихось виключних пізнавальних проблем. Також це стосується питання теоретичного й ціннісного навантаження історичного знання. Данто називає помилкою Бекона переконання, що науковець чи історик починають своє дослідження з вивчення «чистих» фактів, вони обидва потребують теоретичної підготовки, щоб взагалі почати щось досліджувати. Окремої уваги потребує характерна особливість історії як науки, відповідно до якої історик, як обґрунтовано доводить Данто, часто знає більше і краще про події, котрі він вивчає, аніж учасники чи очевидці цих подій.
Rawls' Theory of International Justice: A Brief Reconstruction and Critical Commentary
Authors: Stampoulis Charilaos
Published: December 2022

The aim of this paper is to offer a concise and faithful account of Rawls’ theory of international justice, in an effort, first, to elucidate the structure of the argument that is advanced in that theory and, second, to present a critical assessment of it. The critical assessment section attempts, on the one side, to cope with crucial methodological issues, which have a more general bearing upon Rawls’ overall political philosophical position, including the constructivist perspective of theory making and the division between a political conception and a comprehensive doctrine; on the other side, to weigh up a set of substantive claims made in the Rawlsian theory of international justice, including the recognition of peoples as the fundamental subjects of international law, the toleration of the so-called decent peoples and the considerably thin construal of human rights encompassed in The Law of Peoples. The paper attempts to provide a series of reasons that could be well-suited to explicate its author’s doubts about the soundness of the Rawlsian theoretical perspective with regard to both its formal methodological features and its more content-oriented convictions.
Production of effervescent tablet from jambolan (Syzygium cumini L.) fruit
Authors: Minh Nguyen Phuoc
Published: December 2022

Jambolan (Syzygium cumini L.) fruit contained numerous phytochemical and bioactive constituents beneficial for human health. However, this underutilized fruit was highly susceptible to quality degradation after harvesting. Due to the seasonality and perishability of the jambolan fruit, it’s very necessary to convert this valuable fruit into instant, stable and convenient form for long-term consumption. This research was conducted at STNanotech laboratory in 2021 to evaluate the exploitation of jambolan fruit for juice extraction, spray drying and effervescent tablet production. Different variables of spray drying conditions such as proportion of wall material (maltodextrin 8-16%), inlet/outlet drying temperature (150/80, 160/85, 170/90, 180/95, 190/100 oC/oC), feed flow rate (7.5-17.5 ml/min) were deeply investigated on physicochemical and antioxidant properties of spray-dried jambolan powder (SDJP). In preparation of effervescent tablet, the spray-dried jambolan powder (SDJP) was mixed with sodium bicarbonate (SB) and magnesium stearate (MS) in five different formulas: F1 (65/10/25), F2 (65/5/30), F3 (70/10/20), F4 (65/15/20), F5 (70/15/15). Results showed that jambolan extract should be spray-dried with maltodextrin 14% as wall material (WM), inlet/outlet drying temperature 170/90 oC/oC, feed flow rate (FFR) 12.5 ml/min to obtain the optimal particle size 7.94±0.05 µm, solubility 96.80±0.02%, yield 56.71±0.01%, microencapsulation efficiency (ME) 93.25±0.05%, total phenolic content (TPC) 298.45±0.79 mg GAE/100 g, anthocyanin content (AC) 76.59±0.06 mg/100 g, and antioxidant activity (AA) 85.63±0.04%. The jambolan effervescent tablet produced by formula F2 (65/5/30) achieved the optimal hardness 47.24±0.05 N, disintegration time (DT) 271.05±2.03 s, TPC 201.03±1.28 mg GAE/100 g, AC 40.89±0.30 mg/100 g, AA 73.12±0.24% and overall acceptance (OA) 8.81±0.05. Jambolan fruit could be utilized to produce spray-dried powder and its effervescent tablet as a versatile functional food with excellent physicochemical, antioxidant and sensorial characteristics under safe and convenient way for all year round.
The Dutch Foreign Policy in the National Historiography of the Nineteenth and Early Twentieth Centuries
Authors: Shatokhina-Mordvintseva Galina
Published: December 2022

In this article the author examines the stages of formation of the Dutch historiography on the issues of the country's foreign policy in the nineteenth and early twentieth centuries. The author has tried to identify all the studies in the field during the specified period and present them in chronological order. Interest in the development of Dutch foreign policy became particularly evident after the Belgian revolution of 1830, while the authors of numerous polemical writings were mainly politicians, statesmen representing the liberals and conservative clergymen (J.R. Thorbecke, G. Groen van Prinsterer), and law professors. In the middle of the century, as the international situation grew increasingly tense, political journalism gradually gave way to the first scholarly studies of foreign policy. A further step that gave impetus to historians' work on the subject was the work of the jurist G.W. Vreede, author, in addition to a large number of serious works on Dutch foreign policy, of a truly groundbreaking work on the history of the country's diplomacy since the end of the sixteenth century. 
In the early decades of the formation of the Dutch school of history only isolated dissertations on the subject of foreign policy appeared, namely works by the jurist J.C. de Jonge and the accomplished professional historians H.T. Colenbrander, N. Japikse and A.J. D'Ailly. They were written under the supervision of the country's leading historians, R.J. Fruin and P.J. Block at Leiden University and H.K. Rogge at the University of Amsterdam. At the beginning of the twentieth century, foreign policy became the subject of research by A. Kalshofen, S.V.A. Drossars, dissertators in the Department of National History at Leiden University.
The author’s aim is to draw the attention of Russian scholars to the history of small states, the history of the Netherlands in particular, and its relevance stems from the possibility of working with many of the Dutch library collections, which have already been digitised in recent years. This allows one to embark on a more detailed study of the problems of foreign policy of the Netherlands in the Modern and Contemporary era and to introduce a set of new sources and monographs into the academic circuit.
Russia’s Relations with North and South Korea in the New Reality
Authors: Dyachkov Ilya
Published: December 2022

Despite Asian countries’ usually keeping at distance from European conflicts, Russian special military operation in Ukraine that started in February 2022 has influenced Russia’s ties with the DPRK and the Republic of Korea. Whereas the DPRK openly supported Moscow, Seoul joined the West in condemning Russian actions. Still, a lot of finer details come to light when assessing real prospects of our bilateral relations with Korean neighbors.
Although Moscow and Pyongyang are en rapport politically, practical cooperation is negligible due to UNSC sanctions and strict restrictions North Korean authorities introduced to combat COVID-19. Seoul had introduced sanctions against Russia which resulted in Russia listing the Republic of Korea as an ‘unfriendly state.’ Still, South Korea is reluctant to dismantle their relations with Russia which would mean losing Russian market, assets and the country and access to Russian supplies. So, South Korean authorities and businesses have started a complex balancing act trying to reconcile increasing pressure from their ‘senior ally’ with own interests.
 
Russia should build relations with North and South Korea proceeding from our national interests and an understanding of objective factors that limit our interaction. It is important to identify and use new opportunities to work with our close neighbors and protect our ties amidst the crisis, since the new reality requires we use all means and assets to protect our interests.

Published: December 2022

Abstract: The demand of electricity that keeps increasing necessitates additional electricity generation. The highly dependence of power generation on fossil fuels implies the intensive use of this resources that may cause them finish sooner than predicted. On the other hand, the use of fossil fuels for transportation is quite dominant. The development and use of electric transportation system is a solution for reducing fuel consumption. However, the electricity for supplying the electric transportation system is mainly from the generation system that uses fossil fuels. For further improvement, the energy supplied to the transportation system should come from the renewable energy generation. This may lead to minimum use of fossil fuels besides giving minimum effect on environment. This paper presents the development of renewable energy generation where the generated power is used to supply the storage that charges the electric bicycle. The power is generated by solar photovoltaic panels and it is saved in a battery. The charging for the bicycle is taken from the battery. The developed system is off-grid since the system may be placed in the non-electrified area. This prototype will be a role model regarding the combination of renewable energy generation and green transportation system.

Batik is one of the most attractive and precious methods which enhances the value of leather even of a very simple one. Batik is mainly practised on clothes. Practising batik on leather is not yet mainstreamed. In the batik technique on leather, wax is typically used as a colour barrier and then different wax removers are used to remove wax from the leather surface. Wax and wax removers create some complexities in leather. This study aims to explore different techniques such as tie-dye, block, splashing, and painting to create a batik effect on the chrome re-tanned leather surface. Then different colour fastness tests (rub, wash, perspiration, light, and heat fastness) are accomplished to assess the quality of batik leather. The resulting appearance and quality of the finished leathers are assessed with greyscale and found at a satisfactory level. In each fastness test, results in the greyscale ratings are 4/5 to 5. The produced leathers are then used for making coin purses, key cases, and ladies' purses. So, the new batik techniques are recommendable for practice.

Published: December 2022

Digital storytelling (DST) is one of the areas which has entered the field of foreign language education and has proved to be beneficial in learning different language skills. However, it remains underexplored whether and how DST can affect learners’ writing skill and motivation to write. The present study sought to investigate the impact of DST on young EFL learners’ writing skill and motivation to write through mixing quantitative and qualitative research methods. The data were collected through pre- and post-tests of writing and interviews from 22 EFL learners. The learners were asked to create digital stories based on the pre-taught topics, vocabulary, and structures in their course book within a 10-week implementation process. In addition, structured interviews were carried out to investigate the impact of DST on the learners’ motivation. The result was a proof to the efficiency of DST in improving the learners’ writing skill. Also, the thematic analysis of the interview data indicated that employing DST had a positive impact on young EFL learners’ attitude toward writing and increased their motivation. The primary takeaway from this study is that DST can provide a more favourable and enjoyable teaching context to instruct writing to EFL learners.

Published: December 2022

Although the broad concept of celebrity endorsement is not new, the popularity of its Social Media version skyrocketed over the last several years, being exploited even by notorious and top-tier companies. A substantial body of academic research approached the traditional celebrities’ endorsement, leaving rather unstudied the impact of digital celebrities’ endorsement power. Aiming at reducing the literature gap, the present study investigated the audience’s attitude towards online endorsement that includes famous vloggers (a category of digital celebrities) and its effect on future behaviors. In this sense, a conceptual model was tested using the structural equation modeling technique in the context of a primary research. The results unveiled that the perceived characteristics of the celebrity reflect on the overall attitude towards the vlogger. Despite influencing the attitude towards endorsed products, video content, product recommendation and engagement on source’s Social Media channel, the attitude towards the celebrity didn’t have a direct effect on purchase intention. The attitude towards the video content affected the attitude towards the product and both were shown to have a positive influence on purchase intention and recommendation. Yet, only the first one reflected on actions concerning celebrity’s online platform.

Authors: Trujillo Casas , Paola Jennyfer
Published: December 2022

The increase in academic mobility in Europe has inspired many to contribute to the special literature regarding internationalization. This contribution is quite timely, as the need to understand the ties between higher education and internationalization is great. Considering that mobility has predominantly occurred in Western Europe, special attention must be focused on Eastern Europe’s Higher Educational endeavors. This study focuses on the Central European country of Hungary, and therein more specifically on its second largest city, Debrecen. The University of Debrecen currently hosts around 7000 international students, and every year this number increases. With such promising and ever-increasing numbers, it is a constant mission of the university to research and report on the life experiences of its international students, regarding their academic, social, and cultural aspects. In this present study the focus will be the social aspect of students whose nationality is represented by more than one hundred persons at the university. Content analysis was employed to analyze structured interviews to identify categories. The findings reveal four main categories to be relevant in their social adaptation: (1) the university, (2) networks students build, (3) language barriers, and (4) healthcare.
Sexually Dimorphic Association of Circulating Plasminogen Activator Inhibitor-1 Levels and Body Mass Index with Cerebrospinal Fluid Biomarkers of Alzheimer’s Pathology in Preclinical Alzheimer’s Disease
Authors: Eruysal Emily , Ravdin Lisa , Zhang Cenai , Kamel Hooman , Iadecola Costantino , Ishii Makoto
Published: December 2022

Background: Plasminogen activator inhibitor-1 (PAI-1), an inhibitor of fibrinolysis that is associated with adiposity, has been implicated in Alzheimer’s disease (AD) pathogenesis. However, whether circulating PAI-1 levels are altered during preclinical AD remains unclear. Objective: To measure plasma PAI-1 levels in cognitively normal cerebrospinal fluid (CSF) AD biomarker positive and biomarker negative participants and to examine the association of plasma PAI-1 levels with CSF AD biomarkers and Mini-Mental State Examination (MMSE) scores. Methods: In this cross-sectional study, plasma PAI-1 levels were measured in 155 cognitively normal (Clinical Dementia Rating, CDR 0) non-obese older adults. 29 men and 26 women were classified as preclinical AD by previously established CSF tau/Aβ42 criteria. All analyses were sex stratified due to reported sex differences in PAI-1 expression. Results: Plasma PAI-1 levels were associated with body mass index (BMI) but not age in men and women. In men, plasma PAI-1 levels and BMI were lower in preclinical AD compared to control. Plasma PAI-1 levels were positively associated with CSF amyloid-β42 (Aβ42) and CSF Aβ42/Aβ40 and negatively associated with CSF tau/Aβ42, while BMI was positively associated with CSF Aβ42 and negatively associated with CSF p-tau181 and CSF tau/Aβ42. In women, plasma PAI-1 levels and BMI were similar between preclinical AD and control and were not associated with CSF AD biomarkers. For men and women, plasma PAI-1 levels and BMI were not associated with MMSE scores. Conclusion: These findings suggest that there are significant sex differences in the systemic metabolic changes seen in the preclinical stage of AD.

Published: December 2022

Background: Modern prodromal Alzheimer’s disease (AD) clinical trials might extend outreach to a general population, causing high screen-out rates and thereby increasing study time and costs. Thus, screening tools that cost-effectively detect mild cognitive impairment (MCI) at scale are needed. Objective: Develop a screening algorithm that can differentiate between healthy and MCI participants in different clinically relevant populations. Methods: Two screening algorithms based on the remote ki:e speech biomarker for cognition (ki:e SB-C) were designed on a Dutch memory clinic cohort (N = 121) and a Swedish birth cohort (N = 404). MCI classification was each evaluated on the training cohort as well as on the unrelated validation cohort. Results: The algorithms achieved a performance of AUC  0.73 and AUC  0.77 in the respective training cohorts and AUC  0.81 in the unseen validation cohorts. Conclusion: The results indicate that a ki:e SB-C based algorithm robustly detects MCI across different cohorts and languages, which has the potential to make current trials more efficient and improve future primary health care.

Published: December 2022

Background: The metabotropic glutamate receptor 5 (mGluR5) is widely expressed in postsynaptic neurons and plays a vital role in the synaptic plasticity of the central nervous system. mGluR5 is a coreceptor for amyloid-β (Aβ) oligomer, and downregulation or pharmacological blockade of mGluR5 presents the therapeutic potential of Alzheimer’s disease (AD). However, the abnormality of mGluR5 in the pathogenesis of AD and its mechanism of pathology is not clear. Objective: In this study, we would like to investigate the expression of mGluR5 in the process of AD and explore the effects and the underlying mechanisms of antagonizing mGluR5 on cognitive function, synaptic structure, and inflammation in 5xFAD mice. Methods: mGluR5 expression and interactions with PrPc in 5XFAD mice were detected using western blot and co-immunoprecipitation. The selective mGluR5 antagonist MPEP was infused into 4-month-old 5XFAD mice for 60 consecutive days. Then, cognitive function, AD-like pathology and synaptic structure were measured. Further observations were made in mGluR5 knockdown 5XFAD mice. Results: mGluR5 expression was increased with Aβ levels at 6 months in 5XFAD mice. mGluR5 antagonist rescued cognitive disorders, promoted synaptic recovery, and alleviated both the Aβ plaque load and abnormal hyperphosphorylation in 6-month-old 5XFAD mice. Meanwhile, the results were validated in mGluR5 knockdown mice. Blockade of mGluR5 efficiently alleviates AD-like pathologies by inhibiting the PI3K/AKT/mTOR pathway and activates autophagy in 5XFAD mice. Furthermore, antagonism of mGluR5 attenuated neuroinflammation by inactivating the IKK/NF-κB pathway. Conclusion: These findings suggest that mGluR5 may be an effective drug target for AD treatment, and inhibition of the mGluR5/PI3K-AKT pathway alleviates AD-like pathology by activating autophagy and anti-neuroinflammation in 5XFAD mice.

Influence of psychological hardiness on academic achievement of university students: The mediating effect of academic engagement
Authors: Meng Qian , Jia Wenxiu
Published: December 2022

BACKGROUND: The dropping out of university students is a serious problem faced by higher education all over the world. Studies have shown that academic hardiness is a positive psychological variable to prevent students from dropping out of university and academic burnout. Psychological hardiness can reduce the dropping out by increasing university students’ academic engagement and academic achievement. OBJECTIVE: This study aims to discover the influence of psychological hardiness on university student’s academic achievement and the mediating role of academic engagement in the relationship between psychological hardiness and academic achievement. A cross-sectional study was conducted among 615 participants. METHODS: Pearson correlation coefficients were conducted to analyze the relationships between psychological hardiness, academic engagement and academic achievement. Mediation analysis was used to evaluate the mediating role of academic engagement in the relationship between psychological hardiness and academic achievement. RESULTS: The research indicated a closely significant association between psychological hardiness, academic engagement and academic achievement. Psychological hardiness can directly predict academic achievement and can also indirectly predict academic achievement through the intermediary effect of academic engagement. CONCLUSION: This study could have important implications for research by linking psychological hardiness and academic achievement. The results suggest that universities should pay attention to the positive role psychological hardiness plays in improving university students’ academic achievement. This study also benefits the university administrators, especially, those dealing with university students at the risk of dropping out and high academic stress.

Published: December 2022

BACKGROUND: Parachutists are generally recognized as a “high-risk” group among military personnel. However, the findings came mostly from data analysis without soldiers as subjects. OBJECTIVE: This study aimed to investigate the injury prevalence in Chinese paratroopers on-site and determine the relationship between injury and risk factors encountered during parachuting and land-based training. METHODS: This study consisted of a field study with questionnaire and an experiment on muscle load during the simulated training exercise of platform jumping with surface electromyography (EMG), in which 7230 paratroopers and 38 soldiers were involved respectively. Chi-square test was used for the injury rate analysis, ANOVA and t-test for comparison of EMG data, and logistic regression for the analysis of multiple factors. Taking both intensity and time into consideration, jump-years (J-yrs) was used as a complex indicator for exposure to parachuting. Either injury per 1000 jumps or injured persons per 100 soldiers were calculated as injury prevalence. RESULTS: The overall injury rate among Chinese parachutists was found to be 13.9 injuries per 1000 parachute jumps and 24.5% based on personnel. The person-based injury rate increased with the exposure level significantly (χ2 = 142.06, 2-sided, P < 0.05; trend test also significantly). Among the identified risk factors the uneven terrain was ranked as the most important one by logistic analysis. The EMG amplitude in MVE% increased with the platform height of all the 8 measured muscles and even reached 100% in 4 muscles, showing a high impact at landing. In addition, some characteristics of parachuting injury were also revealed by the injury type and site analysis. CONCLUSION: A dose-response relationship between parachuting and injury was observed significantly in the survey of Chinese paratroopers. Their injury rate was found to be relatively higher than the reported internationally. Landing impact as a critical point for injury seemed to be proved by the investigation and also the experiment with EMG measurement. It is suggested for future studies, to use the person-based injury rate, landing studied in work physiology and with consideration of different landing skills.
The incompleteness of the Schrodinger equation in classical limit
Authors:   Department of Physical Electronics, Masaryk University, Brno, Czech Republic, Pardy Miroslav
Published: December 2022

The Schrodinger equation with the nonlinear term is derived in the framework of the Dirac heuristics. The particle behaves classically in case the mass of it is infinite. The nonlinear term is crucial and involves new physical constant b. The constant can be measured by the same methods that were used in the case of the Casimir effect (Spaarnay, 1958; Tabor et al., 1969). Of course, the experimental procedure is based on well educated experimenters. The new experiments, different from the Zeilinger ones, are proposed, with Faraday simplicity, for the determination of this new very small constant b. The article is the extended and perfectionized version of the articles by author (Pardy, 1993; 1994; 2001).

Authors:   V.O. Sukhomlynskyi National University of Mykolaiv, Ukraine, Molotylnikova Vira
Published: December 2022

The article presents varieties and variants of relaxation techniques advisable to use after intense physical exertion. The concept of "relaxation" and understanding of its role in physical education to maintain health and harmonious development of youth are considered. Considering the fact that one of the main trends in sports remains the increase in the intensity of training and the need to improve the results of competitions, the problem of restoring the athlete's performance capacity after physical exertion is extremely relevant today. Understanding the causes of fatigue and the physiological mechanisms of recovery, control over the relevant processes, the rational use of modern methods of body relaxation and means of recovery are important for assessing the impact of physical stress on the body, the effectiveness of training programs, identifying overtraining, determining the optimal rest time after physical exercises, and therefore, are necessary to improve the athlete's training and achieving high results.
