The Effects of Internationalization Drivers on Strategy and Performance Relationships in Overseas Markets
Authors:   The Korea International Trade Research Institute, Piao Zengnan , Kim Jin-Soo
Published: May 2024

Purpose - The purpose of this study is to examine the differences in overseas expansion strategies and performance for Chinese export companies according to internationalization drivers.
Design/Methodology/Approach - This study conducted a questionnaire survey after deriving a research model and research hypothesis based on the research purpose presented above. We then conducted an empirical analysis based on the collected questionnaire. In the analysis process, the hypothesis was verified using multi-group analysis after verifying the reliability and validity of the measurement tool.
Findings - To summarize the research results, first, it was found that companies with strong internationalization drivers have a stronger impact on management performance via global marketing strategies, strategic alliances, and levels of integration than companies with weak internationalization drivers. Second, in the case of incremental internationalization companies, companies with weak internationalization drivers had a stronger impact on management performance than companies with strong internationalization drivers.
Research Implications - The implications of this study are that first, global marketing strategies have foreign costs in uncertain overseas markets, and this study found that these foreign costs can be supplemented through the combination of other strategies. In other words, this suggests that Chinese companies need to combine direct investment, such as cooperation with local partners or the establishment of overseas sales companies, in order to maximize the standardization strategy. Second, when the driving force for internationalization is weak, gradual internationalization is required. This is because the more negative the overseas market economy, the lower the risk probability through the continuous accumulation of experience.

Human Capital and the Quality of Foreign Direct Investments
Authors:   London South Bank University, DELEVIC Uros
Published: May 2024

The purpose of this study is to analyse to what extent the difference between the quantity and quality of Human Capital (HC) is relevant to the quantity and quality of inward Foreign Direct Investments (FDI). Most developing economies keep attracting multinational enterprises (MNEs) with short-term goals in labour-intensive industries, with little or no embodiment in the local environment. As such, low-valueadding investments erode the national HC base, leading to the vicious cycle of lowquality investments. The legitimate policy question is whether countries are unable to attract high-quality investment due to the low quality of HC. This study, which combines traditional and more advanced proxies of HC, considers a sample of 54 developed and developing countries. It is found that the role of HC quality in FDI attraction is industry-specific and that it varies depending on the country’s level of development. The quality of HC seems to matter relatively more for high-quality FDI than for overall FDI.
Lost in Translation; The Evolution of Spanish Translations and the Black Legend in England from 1578 to 1740
Authors: Caster Emma C
Published: May 2024

This paper traces the evolution of the Black Legend using Spanish accounts of the colonization of the Americas published in English from 1578 to 1740. The Black Legend, largely spread by English, Dutch, and German Protestants, was an anti-Catholic and anti-Spanish narrative demonizing the Spanish colonization of the Americas. Relying in particular on the English appropriation of Spanish Friar Bartolomé de las Casas’s Short Account of the Destruction of the Indies, originally published in Spanish in 1552, the thesis argues that English editions of the text reflect England's political and religious turmoil in the 16th and 18th centuries. Previous work on the Black Legend centered on how the authors of New World accounts intended to have their work received in Europe. By studying printed paratexts, including dedicatory letters to patrons, letters to the readers, and the translations themselves, I show how English publishers and translators, and the statesmen who sponsored these publications sought to use Bartolomé de Las Casas's accounts as political. The conquest of the New World brought enormous wealth and power to Spain. At the same time, throughout this period, England suffered religious and political conflicts that boiled over into civil war in the mid-17th century. Many in England feared being overrun by a Catholic Empire or overthrown by Catholics from within. Facing various religious and political crises at home English leaders and booksellers used translations of Las Casas's work to advance their own hopes of British imperial expansion in the New World and to encourage the English to unite in the face of the Spanish threats, such as the Netherlands Civil War and Spanish Armada.

Self-regulation is one of the main resources contributing to the productive realization of activity and getting satisfaction from life. The aim of the study was to investigate the role of different aspects of self-regulation in the development of intrinsic motivation to practice sports and the level of life satisfaction in athletes. To study different aspects of self-regulation, the «Self-Government Test» of J. Kuhl and A. Fuhrman was used. To study the level of intrinsic motivation «The Sport Motivation Scale» was used. The «Life Satisfaction Scale» and «The Negative and Positive Emotion Scale» by E. Diener were used to test the degree of life satisfaction. The research involved 178 athletes aged from 17 to 33 years (M = 19,38; SD = 1,88), having titles from junior to Master of Sports International Class. Regression analysis showed that aspects of self-regulation such as planning, sensitivity to own values and emotional regulation in athletes contribute to a higher level of life satisfaction. A comparison of groups with different levels of self-regulation showed that athletes with higher levels of self-regulation skill are characterized by a more stable internal motivation to do sports and less expression of negative experiences; they experience positive emotions more often. In addition, it has been demonstrated that the most developed indicators of volitional regulation are characteristic of athletes at the initial and professional level of skill, as compared to those who are at the intermediate stage. Thus, self-regulation is one of the most important resources of athletes, important not only for their professional performance, but for a sense of well-being and life satisfaction.
Russian-Language Versions of Inventories Measuring Styles and Effectiveness of Conflict Resolution in Close Relationships
Authors:   Altai State Pedagogical University, Barnaul, Russian Federation, Sychev Oleg , Anoshkin Igor ,   V.I. Vernadsky Crimean Federal University, Simferopol, Russian Federation
Published: May 2024

The article presents the results of the development of Russian-language versions of two inventories proposed by L. A. Kurdek to assess the conflicts in close relationships: The Ineffective Arguing Inventory and the Conflict Resolution Style Inventory. The theoretical basis of these inventories is the result of studies that have revealed the important role of conflict in the stability of the family and described the unproductive pattern of conflict behavior. In a sample of 415 people (43 % men) aged 18 to 66 years old (M = 28.02; SD = 8.05) in premarital (42%) or marital (58%) relationships the factor structure of the questionnaires was confirmed using confirmatory factor analysis, as well as acceptable internal consistency coefficients of the scales were obtained. The validity of the questionnaires is proved by the expected correlations of ineffective arguing and three conflict resolution style scales (positive, conflict engagement, and withdrawal) with indicators of the frequency of conflicts in a couple, relationship satisfaction, attachment style, empathy, and forgiveness. The fourth conflict resolution style (compliance) showed weak correlations with only some validity criteria, which reflects a less important role of this style in the conflicts of premarital and married couples. Correlations of conflict scales with age and duration of relationships were not significant, weak gender differences were revealed only in the tendency to a positive style of conflict resolution (higher in women). The proposed inventories can be useful in future studies of marital conflict, as well as in preventive and counselling work.

Authors: Bhatia Sudhir , Baersch Gudrun
Published: May 2024

The storage of human tissue at room temperature is one of challenging areas. In the literature, there is hardly any reliable method available to achieve this. We have developed a solution called Genekam Tissue Storage Solution (GTSS), which make it possible to do this task. In our laboratory, we have human tissues stored for last 5 year and GTSS is being used to isolate nucleic acid (RNA / DNA) with mini column method as well as magnetic beads isolation method. Isolated nucleic acid has been used in conventional and real time PCR along with conducting hybridization assays. This method offers the possibility for histological as well as pathological samples to be stored at room temperature. The user can transfer the samples between the laboratories at room temperature, which saves shipping costs. Our experiments show that there is no loss of nucleic acid during storage and isolated material can be used to conduct large number of molecular tests on the same sample. Read the publication also. This solution is very economical in the terms of costs.

Authors: Rimet Frederic , Vautier Marine , Kurmayer Rainer , Domaizon Isabelle
Published: May 2024

The objective of this protocol is to provide a reliable and replicable method for the sampling of river micro-phytobenthos and associated microbes in biofilms, to be used in both downstream DNA analysis and algal microscopic counts. The filed protocol is optimized for routine sampling and is in agreement with CEN guidance (NF EN 13946) and CEN technical report (CEN/TR 17245) for the analysis of benthic diatoms from rivers and lakes. The application proposed here in the context of EcoAlpsWater aims in comparing DNA inventories to traditional inventories (microscopy). This protocol is part of the deliverables provided by the WP1 of the Eco-AlpsWater project. All members of the EcoAlpsWater consortium (involving 12 partners : http://www.alpine-space.eu/projects/eco-alpswater/en/home) have contributed to the optimization of this protocol. Phytobenthos-based ecological assessment of running waters is part of the EU Water Framework Directive 2000/60/EC (European Commission) allowing to evaluate the level of nutrients and organic matter pollution in rivers. According to the countries, phytobenthos assessment includes all groups of algae or is based only on diatoms communities. Other periphytic organisms such as fungi, bacteria or microbial eukaryotes as cilates or planktonic (metaphytic) algae are not considered in this assessment method. Further the group of charophytes is covered by the macrophyte ecology method assessment. The recent development of DNA metabarcoding has the potential to complement the traditional biological monitoring based on the direct observation of the organisms, both by reducing sample-processing cost and time and by offering the opportunity to consider a larger taxonomic diversity (e.g. bacteria, heterotrophic micro-eukaryotes …). The protocol described here is dedicated to the sampling of biofilms in rivers both for microscopic enumeration of the phytobenthic community and for downstream DNA analyses of microbial assemblages. This field protocol is based on routine methods used for biofilms sampling and is in agreement with: - CEN, 2014. Water quality - NF EN 13946 - Guidance for the routine sampling and preparation of benthic diatoms from rivers and lakes. Afnor, 1-23. - CEN 2018. Water quality - CEN/TR 17245 - Technical report for the routine sampling of benthic diatoms from rivers and lakes adapted for metabarcoding analyses. CEN, 1-8.

Authors: M Moreno Joao , C Sousa Vitor
Published: May 2024

We present a rapid and efficient protocol for extracting total proteins from adherent fish-derived fibroblasts, specifically optimized for applications in Western blotting and mass spectrometry. The method involves directly dissociating cells from the culture flask into a lysis buffer (e.g. RIPA buffer) followed by centrifugation to collect the total soluble proteins. The use of buffers like RIPA ensures comprehensive solubilization of cellular proteins while preserving their integrity and functionality. This straightforward and reproducible protocol yields high-quality protein extracts suitable for various downstream analytical techniques. Its simplicity and reliability make it an invaluable tool for researchers studying proteomics using fish cell culture.
An Analysis of Badawi’s and Ramzi’s Arabic Translations of the Speech Act of Compliments in Shakespearean Play ‘King Lear’: A Pragmatic Contrastive Study
Authors: Almansoob Najeeb Taher Hasan , Awadh Awadh Nasser Munassar
Published: May 2024

The current study aims at investigating into the appropriateness of the translations of Badawi and Ramiz of the speech act of compliments of the Shakespearean play 'King Lear'. The researcher applied a content analysis of the original version of the play being compared to the Arabic versions as target texts. 20 texts of compliments are sampled for analysis. The study adopted a pragmatic analysis of the speech act under study with reference to the taxonomy of Al-Mansoob, Patil, and Alrefaee (2019). The analysis taxonomy consists of 20 compliment strategies. There occurred a reasonable number of similarities between the original version of the play and the TTs. 75% of Ramzi’s translations and 65% of Badawi’s translations seemed to be identical to the original contexts in preserving the function of the speech act of compliment in the selected 20 texts. The encountered differences between the ST and each of the target translations are not serious to the extent which could break the function of the original context in the target setting as they appropriately preserved the naturalness and smoothness of approximately more than 80% of the target texts. The translators further assimilated each other in handling the ST compliment strategies to the TL context in 12 of the total 20 complimenting contexts.
OFFICIAL IMAGE-BUILDING COMMUNICATION OF CHINA IN UKRAINEDURING THE PANDEMIC AND ITS IMPACTON RELATIONS BETWEEN THE TWO COUNTRIES
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Danylenko S. , Bai Lu Bai Lu ,   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine
Published: May 2024

The article examines the practice of using such formats of informational promotion as "academic journals", "social media" and "traditional mass media" to maintain the official image of China, particularly in the Ukrainian information space during the COVID-19 pandemic (the time frame). Among other things, the authors analyze the opinions and comments of Ukrainian experts in the field of Sino-Ukrainian relations and international communications concerning the development of China's image among Ukrainian citizens. During the pandemic, China's public relations efforts in Ukraine allowed the PRC to avoid accusations of being "guilty" of the worldwide crisis. However, it is pointed out that the dissemination of image-building information about China in Ukraine is currently in its inception stage. A conclusion is made that at the time of the pandemic, no task has been set for those Chinese communication organizations and institutions that can promote wider participation of Ukrainians in the development of Sino Ukrainian relations. Therefore, some stereotypes about China will continue to dominate the collective consciousness of Ukrainians. Negative stereotypes about China have been reinforced by critical information regarding the quality of Sinovac's CoronaVac vaccine supplied to Ukraine; such information has been published in Ukrainian media. This, however, is due to the global competition for vaccine markets. The situation was further exacerbated by the crisis around the Motor Sich Company. Hence, it is necessary to conduct outreach work without the mediation of third countries, particularly of Russia, which wage war against Ukraine and is not interested in Ukraine developing an allied relationship with any country, especially with a global leader like China.
ANTE PAVELIC: CASE STUDY OF CULTUROPATHY AND SOCIOPATHIES OF IDENTITY(VISUAL-ANALYTICAL PORTRAIT). PART 1
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Romanenko Y.
Published: May 2024

The purpose of the article is a visual-analytical portrayal of the personality of Ante Pavelić in the context of the cultural and socio-systemological theory of cultural pathologies and sociopathies of identity. As a result of the study, it was concluded that Pavelić's ethnopolitics, genocidal rhetoric towards the Serbs, as well as the encouraged practices of serbicide reveal a pronounced despotism, necrophilia, a steady predominance of affects of destructive hatred and envy towards ethnic competitors, as well as his real attitude towards the Ustaše, left to the mercy of fate by him to be torn to pieces by the communists while fleeing from Croatia with all the loot, reveals his significant moral defectiveness, as well as gives reason to interpret it as a derivative of the corresponding cultural pathologies and sociopathies of identity.

In the international sphere, which is currently in crisis, Central and Eastern Europe remains a region that strives for a stable balance of power. Among the tangled and networked relationships in the region, strategic narratives play a key role in overcoming communicative and cognitive vulnerabilities. This article examines the theoretical aspects of a narrative approach to the study of the properties of the balance of power used by CEE countries to self-identify and negotiate the distribution of power in the region. Using narrative analysis, this article examines how these narratives influence perceptions of the balance of power in the region and delineate networked communication channels.
Mathematical modeling and analysis of export trends for certain pharmaceutical groups
Authors: Shaikhislamova А. R. , Gasratova N. А.
Published: May 2024

Background. The analysis of the exports of medicines of the Russian Federation (RF) by group 30 (pharmaceutical products) of the commodity nomenclature of foreign economic activity of the Eurasian Economic Union (equal to Harmonized System Code 30, HS 30) is an important task for determining the economic potential of the country in the pharmaceutical industry.

Objective: building an export regression model. Development of an alternative mathematical model of pharmaceutical products’ export, suitable for making the forecast.

Material and methods. Statistical data on HS 30 exports from 2010 to 2021 were taken from an open source: The International Trade Center (Trade Map). Data for 2022 and later for the Russian Federation are not available in open sources. Registration on the website is not required to collect statistics on export and import volumes based on annual data. The well-known statistical methods and methods of mathematical modeling were used. An alternative approach to regression analysis was developed. Technical data analysis was performed using MAPLE (Watcom Products Inc., Canada) and R (Bell Laboratories, USA) software.

Results. Two models were constructed: Model I – a differential model based on cumulative data by year, and Model II – a model of standard regression analysis, the input parameters of which were quarterly export data, and the influencing parameters were a certain group of factors. Model I allowed considering the dynamics of changes in pharmaceutical exports over time (dynamic factors and nonlinear interactions). Model II, in turn, made it possible to determine the dependence of the volume of pharmaceutical exports on various economic indicators, such as gross domestic product, the volume of government procurement, and measures of protectionism. The relative error of Model I does not exceed 10%, which makes it suitable for forecasting.

Conclusion. The construction and analysis of specified models help to provide main information about the trends in pharmaceutical product exports in the RF and assess its potential in the global market. The obtained results can be useful for developing strategies of the pharmaceutical industry development, making management decisions and forecasting future exports.

Published: May 2024

Anticipating volcanic eruptions remains a challenge despite significant scientific advancements, leading to substantial human and economic losses. Traditional approaches, like volcano alert levels, provide current volcanic states but do not always include eruption forecasts. Machine learning (ML) emerges as a promising tool for eruption forecasting, offering data-driven insights. We propose an ML pipeline using volcano-seismic data, integrating precursor extraction, classification modeling, and decision-making for eruption alerts. Testing on six Copahue volcano eruptions demonstrates our model’s ability to identify precursors and issue advanced warnings pseudoprospectively. Our model provides alerts 5–75 hr before eruptions and achieving a high true negative rate, indicating robust discriminatory power. Integrating short- and long-term data reveals seismic sensitivity, emphasizing the need for comprehensive volcanic monitoring. Our approach showcases ML’s potential to enhance eruption forecasting and risk mitigation. In addition, we analyze long-term geodetic data (Interferometric Synthetic Aperture Radar and Global Navigation Satellite System) to assess Copahue volcano deformation trends, in which we notice an absence of noteworthy deformation in the signals associated with the six small eruptions, aligning with their small magnitude.
Climate, nuclear weapons control and cyber threats: three problems or one?
Authors: Sevostyanov P.I. , Mizin V.I.
Published: May 2024

The article analyzes a set of problems related to the mutual influence of three global challenges ofour time, which will determine the configuration of modern society in the medium and long term: climate change, nuclear arms control and cyber threats. The study reveals the role of each of the components and the prospects for their transformation for Russia, the United States and European states. Priority scenarios of state policy within the framework of nuclear deterrence and information security are substantiated. The experience of recent decades reveals that the rejection of security treaties, as a rule, weakens the security of States, rather than strengthens it. Thus, in the course of the study, strategic objectives, the content side and policy options of the Russian Federation in the current international situation were considered, conclusions were drawn regarding the optimality of the chosen strategies for interaction with European partners in the field of arms control, the climate agenda and cyber threats. The authors conclude that it is necessary to create a new generation security architecture through informal consultations on strategic stability, which determine the negotiation plan to be discussed at official negotiations between Russia and the United States. In addition, the authors prove that in the foreseeable future, climate change will have a negative impact on the activities of armies and increase the frequency of their deployment in crisis situations. For this reason, competitive advantages in the defense sector will be determined by the ability of the command to adapt to climate change,reduce damage to military infrastructure and minimise the risks of resource losses due to natural disasters and extreme weather conditions.

Published: May 2024

For a long time, people have been consuming homemade herbal drinks, which are processed traditionally. However, micro, small, medium, and large-scale businesses are now emerging in the production and marketing of ready-to-consume packaged herbal drinks. Research is needed on whether there are differences in consumer motivation in using homemade and industrial-made herbal beverages in terms of the factors of age, gender, education, occupation, and marital status of consumers, as well as how the simultaneous influence of these five variables on the motivation to consume herbal drinks. This study used a sample of 327 people whose data was collected through a digital questionnaire. Data were analyzed using Mann Whitney, Kruskal Wallis, and multiple linear regression. The results showed differences in consumer decisions based on age, education, occupation, and marital status in the choice of herbal drinks, but not gender differences. Most consumers chose the non-packaged type. Simultaneous testing, age, and occupation factors significantly affected consumer decisions, while gender, education, and marital status were not necessary. The results have implications for the segmentation strategy, targeting, and market positioning of the herbal beverage processing industry and the herbal beverage raw material supply industry, better market understanding, more targeted product development, more effective promotional interventions, increased public awareness of the benefits of herbal drinks, and government policy support for the herbal beverage industry.

Mixed reality technology is employed to develop immersive experiences, enhancing visitor engagement within museum environments. There are challenges in interface design and sensory accuracy for such mixed-reality applications. This study explored integration of mixed reality technology in museums, emphasizing the enhancement of cross-cultural understanding and visitor engagement. Using advanced three-dimensional printing, significant artifacts from various cultures, including a notable Korean artifact from the Goryeo period, were replicated and digitized. These artifacts were the core of a mixed reality environment that was created using Unity and the MR Software Development Kit and experienced through a HoloLens 2 Head-Mounted Display. This immersive mixed reality experience, comprising three interactive segments, incorporated eye- and hand-tracking technologies to enable deeper engagement with cultural artifacts. The impact of mixed reality on visitor engagement and cross-cultural comprehension was evaluated, revealing a significant increase in visitor involvement and appreciation of cultural diversity. Notably, this study contributes to the evolving narrative of digital cultural heritage by highlighting the role of mixed reality in fostering a cross-cultural understanding and shaping future museum experiences.

The increasingly widespread use of software solutions to digitize training and administrative processes in educational institutions of all levels increases the interest in offering models and software tools for measuring the level of digitalization of educational institutions. The article presents a formal model for evaluating the digital level of educational institutions and a developed prototype of a software tool. The DIGEdu tool enables external evaluators to assess the digital level of educational institutions, automatically calculates their digital levels and generates evaluation and comparative reports. Using the tool, evaluators assessed the digital level of 50 education institutions in Bulgaria. The results from the conducted experiment prove the applicability of the DIGEdu tool for evaluating the digital level of schools. It calculated the digital level of all assessed institutions. Findings showed that most institutions have high digital levels and highlighted a need for measures at the national level to encourage the digitalisation of student admission and administrative processes.

Published: May 2024

Background: We aimed to compare the difference of the chromosomal abnormalities using karyotype analysis and chromosomal microarray (CMA) as well as to evaluate their application in different prenatal diagnosis indications.
Methods: Overall, 3007 pregnant women with prenatal diagnosis indications from Medical Genetics Department of Linyi Women and Children’s Health Care Hospital, who underwent standard G-banded karyotype analysis and CMA, were enrolled from 2018-2022. G-banded karyotype analysis and CMA were undergone simultaneously. All fetuses with genetic variants were enrolled for further analyzing. The frequency and differences of chromosomal abnormalities of the two methods were compared in different prenatal diagnosis indications groups.
Results: CMA improved 4.09% (123/3007) of genetic changes compared karyotype analysis. CMA is on par with karyotyping for detection of aneuploidies and gross unbalanced rearrangements. Serological screening and ultrasound abnormalities were the main indications of prenatal diagnosis. The detection rate of chromosomal abnormalities was highest in non-invasive prenatal testing (NIPT) abnormal group. In the ultrasound abnormality group, the detection rate of genetic variants in nuchal translucency (NT) increased group was higher than other subgroups and there was statistically significant difference in the detection rate of pCNVs. CMA can detect 5.57% (40/718) more genetic abnormalities in ultrasound abnormality group on the normal karyotype. CMA improved 0.67% (20/3007) of genetic changes with clinically significant compared karyotype, brought 3.42% (103/3007) of variants with uncertain significance (VOUS).
Conclusion: CMA identified additional, clinically significant genetic variants on the basis of normal karyotype analysis, brought a proportion of unclear significant variants. All the pregnant women accepted amniocentesis should be informed about their characteristics of karyotype analysis and CMA by genetic counselors.

Background: We started with RNA-seq analysis and aimed to investigate the possibility of secretory protein matrix metalloproteinase-3(MMP3) as a new diagnosis and therapeutic target in cervical cancer.
Methods: The study was conducted on Nov 2021 at the Second Affiliated Hospital of Qiqihar Medical University, Qiqihar, China. Through conjoint analysis of gene expression data as well as survival rate data, we explored the potential secretary proteins associated with cervical cancer carcinogenesis. One hundred patients aged 38-72 years with clinical stage I-IV cervical cancer, and 100 age-matched healthy women were included. The expression changes in serum of clinical patients was detected. We knockdown or overexpressed the secretory proteins then explored its influence on biological function of cervical cancer cells.
Results: By cross-analysis of The Cancer Genome Atlas (TCGA) database and MetazSecKB database, MMP3 gene was most significantly upregulated in cervical cancer patients (P < 0.05). Furthermore, MMP3 protein was remarkably increased in the serum of clinical cervical cancer patients and decreased after receiving treatment. Overexpression of MMP3 in HT-3 cells or culturing new cells using the supernatant of the medium after MMP3 overexpression could increase cell viability (P < 0.05) as well as proliferation (P < 0.05). Knockdown of MMP3 reduced the phosphorylation of PI3K as well as AKT proteins, while the PI3K phosphorylation inhibitors could suppress the impact of MMP3 on increasing cell proliferation as well as viability.
Conclusion: MMP3 could be an underlying target for early diagnosis and treat cervical cancer in the future.
