Quantum criticality in many-body parafermion chains
Authors: Lahtinen Ville , Mansson Teresia , Ardonne Eddy
Published: May 2021

We construct local generalizations of 3-state Potts models with
exotic critical points. We analytically show that these are described by
non-diagonal modular invariant partition functions of products of
Z_3Z3
parafermion or u(1)_6u(1)6
conformal field theories (CFTs). These correspond either to non-trivial
permutation invariants or block diagonal invariants, that one can
understand in terms of anyon condensation. In terms of lattice
parafermion operators, the constructed models correspond to parafermion
chains with many-body terms. Our construction is based on how the
partition function of a CFT depends on symmetry sectors and boundary
conditions. This enables to write the partition function corresponding
to one modular invariant as a linear combination of another over
different sectors and boundary conditions, which translates to a general
recipe how to write down a microscopic model, tuned to criticality. We
show that the scheme can also be extended to construct critical
generalizations of kk-state
clock type models.
Trend Analysis of Crime against Women in Manipur, India
Authors: Shah Baharuddin , Khan Chingiz
Published: May 2021

The issue of women in Manipur is ascribed to two points. One point relates to the positive aspects of women such as their responsible roles in economy, polity and socio-cultural affairs in the state. The other point is focused on the crimes against women in the state. There are many crimes against women in the state such as sexual harassment, rape, molestation, domestic crimes, intimidation, kidnapping, attempt to rape, attempt to molestation, etc. All the major indigenous communities in the state namely Meitei, Muslims locally known as Pangal, tribes such as Naga and some sections of Kuki are the victims of such crimes. This paper is focusing on various forms of crimes against women. In this piece, an attempt has been made to scrutinize the different aspects of crimes against women in Manipur.

Phonetic Reconstruction of Tautovocalic Diphthongs as a Problem of Linguistic Textology (In Nyegoshʼs Epic “Stephen the Little”)
Authors:   Pan-european University Apeiron Banya Luka, Faculty of philological sciences, Marojevic Radmilo
Published: May 2021

The author of this paper explains the interpretation of the diphthongs in the epic ”Stephen the Little” by Serbian poet Petar II Petrovich Njegos from the epoch of romanticism. They are: а) tautovocalic diphthongs in the same word, b) tautovocalic diphthongs at the word boundary and its enclitics, c) tautovocalic diphthongs at the word boundary and its proclitics, d) tautovocalic diphthongs at the boundary of two phonetic words, i.e. in sandhi. The analysis comprises the epic ”The Mountain Wreath” and the epic ”The Ray of the Microcosm”, and some of Njegos`s poems, аs well as examples from Serbian folk poems published in the first collection of folk poems ”Маlа prostonarodnya slavenо‑serbska pěsnarica” by Vuk Stefanovich Karadjich.
Language Policy of the Russian Federation
Authors:   University of East Sarajevo, Faculty of Philosophy, Kosmajac Vesna
Published: May 2021

This paper presents a sociolinguistic analysis of the current linguistic situation in the Russian Federation. Preservation and development of the Russian language represents the national interest of the state. The Russian language has the status of a state language, but, given the large number of ethnic groups living on the territory of Russia, it must not jeopardise other national languages, as this could lead to inter-ethnic conflicts. Some of the key issues Russia is currently facing in this field are: the process of globalisation, the uncontrolled penetration of anglicisms into the Russian language, the adverse impact of the Internet and social networks on literacy, especially with the younger population. All valid rules of the Russian orthography are, in fact, prescribed by the Government of The Russian Federation. Laws regulating the area of language policy are the Constitution of the Russian Federation, the Law on the Languages of the Peoples of the Russian Federation, and the Law on the State Language of the Russian Federation.
Reflections on Theory and Criticism of the ‘Literary Egoʼ. A Comparative Study
Authors: Bottero Stefano
Published: May 2021

The purpose of this essay is to deepen philosophical and critical issues related to the ‘literary Ego’ by articulating the conceptual and theoretical premises of a contemporary corpus. To date, the subject of my study lacks a relative critical literature which is epistemologically developed starting from the philosophical component. In the essay, a thematic reading of the materials relating to the literary subject was actualised, which led to the development of an equally comparative-formal and theoretical-literary discourse. What has been deduced is a character of profound interconnection between the insights offered by reading the essence of the ‘literary Ego’ as an empirical and phenomenological res. In conclusion, an attempt was made to highlight the concreteness of this character, which offers the starting point for further studies.
Equal and Different: Feminism as Radical Humanism
Authors:   University of Nis, Faculty of Philosophy, Mitić Petra
Published: May 2021

In its attempts to defend the right of women to claim their own subjectivity,as well as the equal right to participate in the social system institutions, the mainstream of feminist thinking has been marked crucially by the question of woman and her identity. This question could be said to occupy a central place in feminist texts and discussions which started even before the women’s movement was officially created. But since feminist disagreements about how these issues should be approached appropriately have already resulted in serious misunderstandings and mutually severe accusations, this paper aims at shedding light at the very nature of these polarities. In doing so, the focus has been placed on how the terms equal and different have been theorised. These dissenting voices have certainly proved productive in the context of theory itself, but have done much harm in the domain of social activism which failed to initiate truly substantial changes within western society and culture. The same countereffect is also visible in theory, which has generated a diversity of feminisms, but has definitely failed to offer a comprehensive critique of the perniciously repressive culture. The lack of gender equality has always been an important dimension of this culture, but still just a segment and one particular mechanism of the invisible matrix which has never actually stopped producing binary hierarchies. They are being manifested in different forms today but have retained fundamentally unchanged and unchallenged structures, promoting an ideologically induced perception of reality to appear natural and self-evident. The paper puts forward the claim that a humanistic and anti-capitalist feminism is a framework broad enough to overcome all exclusions and one-sided definitions and to head towards one such comprehensive feminism – bringing us back to the original radicalism of the women’s movement. To do so, it is necessary to reconsider the general confusion within postmodernist discourse, and especially the controversy related to what humanism should stand for today.

Investigating the effect of lab bias on long-term stream chemistry data
Authors: Brown Cindi L. , Miniat Chelcy F. , Knoepp Jennifer D.
Published: May 2021

Long-term (LT) stream chemistry studies are used to examine changes in and responses to the environment. Much of the data collected over long periods of time goes through changes in instrumentation, methods, and personnel potentially resulting in changing values. A data user must understand these measures of data quality through quality control (QC) results to know with certainty if trends are real or attributable to other factors. We used the Web of Science database search engine to search for LT stream chemistry studies. For each study, we then determined: record or study length; if QC was reported; and if QC was used. We found that 33% of papers reported QC in the method, and 12% presented the QC in the results. Next, we conducted a case study on 46 years of stream chemistry data to evaluate the data with and without the application of QC protocols from two watersheds (WS) at Coweeta Hydrologic Laboratory; WS 7; clear-cut in 1967–77 and adjacent WS 2 which serves as a reference. We focused on nitrogen and sulfur due to their importance in understanding the forest ecosystem response to disturbance (NO3) and acid deposition (SO4). We determined average annual dissolved inorganic nitrogen (DIN) export (NH4 + NO3 = DIN) using three methods for censoring values below the method detection limit (mdl): (1) the found value, (2) the value of zero, and (3) one-half the mdl value. We found that DIN export for WS 2/WS 7 was (1) 66.9/831.4 (g ha−1 yr−1), (2) 45.4/808.0 (g ha−1 yr−1), and (3) 72.1/823.2 (g ha−1 yr−1) using the three censoring methods, and that the export estimate was significantly different for WS 2 but not for WS 7 (P = 0.001). We found that on average stream NH4 concentrations were below the mdl 58% of the time until an instrument change in 1994 resulted in improved mdls resulting in fewer data points below detection. We found increased bias for stream SO4 concentration following an instrumentation change from segmented flow analysis to ion chromatography. As a result, stream SO4 concentration data that were bias-corrected declined more rapidly in WS 2 compared with non-bias-corrected data, but not in WS 7. We conclude that including QC results with LT data is essential to verify data validity and give the data user a full understanding of the results.
Development of web enabled water resource information system using open source software for Patiala and SAS Nagar districts of Punjab, India
Authors: Singh Banjeet , Kaur Samanpreet , Litoria Pradeep Kumar , Das Susanta
Published: May 2021

Over the globe, efforts are being made to collect data and develop an adequate water resource information system for optimising its use. India is the largest consumer of water, with an estimated usage of around 300 cubic kilometers per year. Punjab, a north-western state of India, is an example of severe crises aquifer depletion due to unconstrained consumption of groundwater, leading to degradation of its quantity as well as quality. Thus it is of great importance to compile up-to-date information about the water requirement for its appropriate and sustainable use. Remote sensing and geographic information system (GIS) are the technologies that can provide efficient and effective information system to tackle the water quality & water supply planning parameters. Thus, under the present study, a web-enabled water resource information system has been developed in the GIS environment for the SAS (Sahibzada Ajit Singh) Nagar and Patiala districts of Punjab by using the open source software MS4W and pmapper. This system provides digital information of natural, such as drainage, and man-made features like roads, canals, and tube wells with their location and so on, and also provide information related to water level, water quality of wells, and well depth for the study area. Such an information system can be very helpful for the administrators and can serve as a decision support system for planners and policy makers so that the areas where problems related to water quality can be identified and focused upon. The system can provide an effective and meaningful direction for the planning and development of both districts.
Application of ZIF-67 as a crosslinker to prepare sulfonated polysulfone mixed-matrix membranes for enhanced water permeability and separation properties
Authors: Yin Jiulong , Tang Hai , Liu Di , Huang Tingting , Zhu Lei
Published: May 2021

High-performance sulfonated polysulfone (SPSf) mixed-matrix membranes (MMMs) were fabricated via a nonsolvent-induced phase separation (NIPS) method using zeolitic imidazolate frameworks-67 (ZIF-67) as a crosslinker. Acid-base crosslinking occurred between the sulfonic acid groups of SPSf and the tertiary amine groups of the embedded ZIF-67, which improved the dispersion of ZIF-67 and simultaneously improved the membrane strzcture and permselectivity. The dispersion of ZIF-67 in the MMMs and the acid-base crosslinking reaction were verified by energy-dispersive X-ray spectroscopy (EDX), X-ray diffractometry (XRD), Fourier-transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS). The pore structure analysis of MMMs indicated that filling ZIF-67 into SPSf enhanced the average surface pore sizes, surface porosities and more micropore in cross-sections. The crossflow filtrations showed the MMMs have higher pure water fluxes (57 to 111 L m−2 h−1) than the SPSf membrane (55 L m−2 h−1) but also higher bovine serum albumin (BSA) rejection rate of 93.9–95.8%, a model protein foulant. The MMMs showed a higher water contact angle than the SPSf membrane due to the addition of hydrophobic ZIF-67 and acid-base crosslinking, and also maintained high thermal stability evidenced by the thermogravimetric analysis (TGA) results. At the optimal ZIF-67 concentration of 0.3 wt%, the water flux of the SPSf-Z67-0.3 membrane was 82 L m−2 h−1 with a high BSA rejection rate of 95.3% at 0.1 MPa and better antifouling performance (FRR = 70%).

Imidazole Scaffold Based Compounds in the Development of Therapeutic Drugs
Authors: Hu Fanjie , Zhang Lina , Nandakumar Kutty Selva , Cheng Kui
Published: May 2021

Imidazole has an important five-membered aromatic heterocyclic ring, which is available
widely in natural products and synthetic molecules. The special structural characteristics of
imidazole ring enable it to bind with a variety of enzymes and receptors through hydrogen bonds,
coordination, ion-dipole and cation-π interactions, hydrophobic effects, and Van der Waals forces.
These interactions promote several biological activities involving anti-tumor, anti-inflammatory,
anti-microbial, and anti-viral properties. Herein, we review and discuss recent developments in using
imidazole derivatives and their special pharmacological activities for the treatment of various
diseases.
MicroRNAs: Key Regulators in Lung Cancer
Authors: El Founini Younes , Chaoui Imane , Dehbi Hind , El Mzibri Mohammed , Abounader Roger , Guessous Fadila
Published: May 2021

Noncoding RNAs have emerged as key regulators of the genome upon gene expression
profiling and genome-wide sequencing. Among these noncoding RNAs, microRNAs are short noncoding
RNAs that regulate a plethora of functions, biological processes and human diseases by targeting
the messenger RNA stability through 3’UTR binding, leading to either mRNA cleavage or
translation repression, depending on microRNA-mRNA complementarity degree. Additionally,
strong evidence has suggested that dysregulation of miRNAs contributes to the etiology and progression
of human cancers, such as lung cancer, the most common and deadliest cancer worldwide.
Indeed, by acting as oncogenes or tumor suppressors, microRNAs control all aspects of lung cancer
malignancy, including cell proliferation, survival, migration, invasion, angiogenesis, cancer
stem cells, immune-surveillance escape, and therapy resistance; and their expressions are often associated
with clinical parameters. Moreover, several deregulated microRNAs in lung cancer are carried
by exosomes and microvesicles and secreted in body fluids, mainly the circulation, where they
conserve their stable forms. Subsequently, seminal efforts have been focused on extracellular microRNAs
levels as noninvasive diagnostic and prognostic biomarkers in lung cancer. In this review,
focusing on recent literature, we summarize the deregulation, mechanisms of action, functions
and highlight clinical applications of miRNAs for better management and design of future
lung cancer targeted therapies.
Diversity of Woody Species and Biomass Carbon Stock in Response to Exclosure Age in Central Dry Lowlands of Ethiopia
Authors: Ibrahim Temima , Tesfay Fikrey , Geremew Bethel
Published: May 2021

Objective:

Empirical evidence on the potential of area exclosure in the restoration of severely degraded lands is crucially important. Thus, a study was conducted to examine the influence of exclosure age on vegetation structure, diversity, and biomass carbon stock in the central dry lowland of Ethiopia.

Methods:

Exclosures of 5, 15, >20 years old, and adjacent open grazing land were selected. Data on vegetation were collected using 20 × 20 m sampling quadrats which were laid along parallel transect lines.

Results:

The result showed that 17 woody species which represent 9 families were recorded at exclosures and open grazing lands. Shannon-Wiener (H') diversity index ranged from 0.74 (open grazing land) to 2.12 (middle age exclosure). Shannon evenness (E) index was higher in the middle age exclosure (0.80). Woody species basal area and tree density significantly (p < 0.05) increased with increasing exclosure age. The Aboveground woody biomass significantly (p < 0.05) varied from 12.60 (open grazing land) to 68.61 Mg ha-1 (middle age exclosure). Similarly, the aboveground biomass (AGB) carbon stocked was significantly (p < 0.05) higher in the middle (32 Mg ha-1) and old age exclosures (31 Mg ha-1).

Conclusion:

This study indicated that exclusion can restore the degraded vegetation and sequester and stock more atmospheric carbon dioxide in the aboveground biomass. Therefore, open degraded grazing land of the lowland areas can be restored into a promising stage through area exclosure land use management.

How social media making an impact on the field of 3D printing in dentistry – survey study (Preprint)
Authors: Hegedüs Tamás , Kreuter Patrik , Bányai Dorottya , Végh Ádám , Hermann Péter , Végh Dániel
Published: May 2021

BACKGROUND

3D printing is a rapidly developing technology in the healthcare industry and in dentistry as well. Regarding its application it shows clear evidence that this area of digital dentistry is in everyday usage among all of the fields including prosthodontics, orthodontics, maxillofacial surgery and oral implantology. In spite of gaining ground, there is a lack of information about how the specialists (dentists, dental technicians) use the additive technology.

OBJECTIVE

Our research group aims to investigate the impact of social media on the additive manufacturing technology among dental specialists and the everyday usage of 3D printing.

METHODS

The paper investigates the everyday usage of 3D printing by the specialists via an online survey (Google Form). The questions of the survey try to draw a conclusion about the number of 3D printers used, the accessibility of devices, the annual cost and the designing programs. Since the specialists tend to build online communities on social media, during our research we spread the questionnaire by our platforms on LinkedIn, Facebook, and Instagram.

RESULTS

The 114 feedback were from 20 countries, most of them were from Hungary (23.7%), the United States (18.4%), and the United Kingdom (7.9%). Most of the participants were dentists (62) and dental technicians (29) but also CAD / CAM specialists (23) filled out our survey. The participants had an average of 3.8 years (± 0.7) of experience in the 3D printing field, and own a total of 405 printing devices (3.6 on average/person).

CONCLUSIONS

The impact of social media on this research field is more and more growing hence we support the specialists to join the virtual communities on the adequate platforms. The article intended to provide a practical overview of feedback and give a direction for those dentist colleagues who are willing to invest in this technology. From our survey we could state that additive technology is widening our applications and our services, what we can provide for our patients.
Virtual Reality Simulation for Disaster Preparedness Training in Hospitals: Integrated Review (Preprint)
Authors: Jung Younhyun
Published: May 2021

BACKGROUND

A critical component of disaster preparedness in hospitals is experiential education and training of health care professionals. A live drill is a well-established, effective training approach, but cost restraints and logistic constraints make clinical implementation challenging, and training opportunities with live drills may be severely limited. Virtual reality simulation (VRS) technology may offer a viable training alternative with its inherent features of reproducibility, just-in-time training, and repeatability.

OBJECTIVE

This integrated review examines the scientific evidence pertaining to the effectiveness of VRS and its practical usefulness in training health care professionals for in-hospital disaster preparedness.

METHODS

A well-known 4-stage methodology was used for the integrated review process. It consisted of problem identification, a literature search and inclusion criteria determination, 2-stage validation and analysis of searched studies, and presentation of findings. A search of diverse publication repositories was performed. They included Web of Science (WOS), PubMed (PMD), and Embase (EMB).

RESULTS

The integrated review process resulted in 12 studies being included. Principle findings identified 3 major capabilities of VRS: (1) to realistically simulate the clinical environment and medical practices related to different disaster scenarios, (2) to develop learning effects on increased confidence and enhanced knowledge acquisition, and (3) to enable cost-effective implementation of training programs.

CONCLUSIONS

The findings from the integrated review suggested that VRS could be a competitive, cost-effective adjunct to existing training approaches. Although the findings demonstrated the applicability of VRS to different training scenarios, these do not entirely cover all disaster scenarios that could happen in hospitals. This integrated review expects that the recent advances of VR technologies can be 1 of the catalysts to enable the wider adoption of VRS training on challenging clinical scenarios that require sophisticated modeling and environment depiction.
Aftershock of a vaccination gap: the measles epidemics in Tirana, 2018 (Preprint)
Authors: Ulqinaku Dritan , Vyshka Gentian
Published: May 2021

UNSTRUCTURED

Tirana, capital of Albania, has seen an acute increase in the measles cases during 2018, with a total figure surpassing 1000 of patients. The outbreak happened while the country was only witnessing very few and isolated cases for several years, as to have officially declared the disease as eradicated. Several reasons might have led to the outbreak of this epidemic, with a clear vaccination gap in the years 1997-1998. Authors discuss this undervaccination as well as other factors detectable in this group of patients, such as a peak in the first-year age infants and the prevalent distribution in the suburban area of the city, actually inhabited from a large number of internally migrated people.

UPT SMP Negeri 6 Gresik adalah salah satu lembaga pendidikan yang menerapkan model pembelajaran Teams-Games-Tournament (TGT) dalam kegiatan belajar-mengajar di kelas. Model pembelajaran TGT dapat membantu siswa dalam memahami materi pelajaran dengan mengandalkan teman sebagai tutor sebaya dan memanfaatkan unsur permainan di dalamnya. Model pembelajaran yang diterapkan saat ini memiliki beberapa kendala, di antaranya guru membentuk kelompok secara konvensional, yang dapat mengurangi jam belajar-mengajar di kelas. Pembentukan kelompok secara konvensional memungkinkan pembagian kelompok yang tidak merata, yaitu terdapat kelompok yang terdiri atas siswa yang memiliki nilai unggul saja atau rendah saja. Selain itu, guru membuat papan permainan berupa Teka-Teki Silang (TTS) secara konvensional. Papan permainan dibuat sebelum penyampaian materi diberikan dan dibuat juga sejumlah materi dan kelompok yang ada. Fitur pengelompokan dikembangkan dengan menerapkan algoritme k-means clustering. Proses pengembangan sistem ini menerapkan model pengembangan waterfall dan framework CodeIgniter. Analisis kebutuhan yang dilakukan untuk aplikasi ini menghasilkan empat aktor, 37 kebutuhan fungsional, dan satu kebutuhan nonfungsional. Pengujian dilakukan dengan menggunakan teknik blackbox testing dan whitebox testing.

To examine the validity of race/ethnicity-specific comorbidity adjustment scores in estimating in-hospital mortality.
Materials & methods:
Using 2007–2014 data from the State Inpatient Databases (SID), we compared the performance of derived race/ethnicity-specific composite scores to the existing scores and binary Elixhauser comorbidity measures at estimating in-hospital mortality.
Results:
In the overall validation sample (N = 9,564,277), our index (c = 0.80; 95% CI: 0.79–0.80) discriminated better than the van Walraven score (c = 0.79; 95% CI: 0.79–0.79), SID 29 (c = 0.78; 95% CI: 0.78–0.79) and SID 30 (c = 0.78; 95% CI: 0.78–0.78), but was not superior to the binary indicators (c = 0.80; 95% CI: 0.80–0.80). Similar findings were observed in individual populations of White and Black patients. All models showed weak calibration.
Conclusion:
Race/ethnicity-specific indexes discriminated slightly better than existing composite measures at modeling in-hospital mortality in individual subgroups of race/ethnicity.

O estudo aborda a temática de Educação do Campo com foco na formação de educadores. Tem por objetivo fazer uma breve análise do currículo do curso de Pedagogia do Centro de Ciências Sociais, Saúde e Tecnologia - CCSST da Universidade Federal do Maranhão – UFMA/Campus de Imperatriz, buscando identificar a existência do debate sobre Educação do Campo na formação dos educadores. Utilizou-se como metodologia revisão bibliográfica, com destaque para os estudos de Arroyo (2004; 2012), Caldart (2002; 2004), Candau (2007) e Molina (2004; 2015), além de análise documental. Os resultados permitem identificar que o debate no curso de pedagogia sobre a temática em questão é realizado no âmbito de uma disciplina optativa, e, portanto, com pouca frequência. Todavia, outras disciplinas também apresentam em suas ementas conteúdos afins, possibilitando o contato com a discussão, embora de forma limitada, bem como o entendimento da sua importância no contexto plural em que os educadores são inseridos.

Brain development is a unique process characterized by mechanisms defined as neuroplasticity (synaptogenesis, synapse elimination, neurogenesis, and cerebral angiogenesis). Numerous neurodevelopmental disorders brain damage, and aging are manifested by neurological deficits that are caused by aberrant neuroplasticity. The presence of stem and progenitor cells in neurogenic niches of the brain is responsible for the formation of new neurons capable of integrating into preexisting synaptic assemblies. The determining factors for the cells within the neurogenic niche are the activity of the vascular scaffold and the availability of active regulatory molecules that establish the optimal microenvironment. It has been found that regulated intramembrane proteolysis plays an important role in the control of neurogenesis in brain neurogenic niches. Molecules generated by the activity of specific proteases can stimulate or suppress the activity of neural stem and progenitor cells, their proliferation and differentiation, migration and integration of newly formed neurons into synaptic networks. Local neoangiogenesis supports the processes of neurogenesis in neurogenic niches, which is guaranteed by the multivalent action of peptides formed from transmembrane proteins. Identification of new molecules regulating the neuroplasticity (neurogenesis and angiogenesis). i. e. enzymes, substrates, and products of intramembrane proteolysis, will ensure the development of protocols for detecting the neuroplasticity markers and targets for efficient pharmacological modulation.
Effects of a Threat and Alliance on International Cooperation: Comparison of Inter-Korean and Turkish-Armenian Railway Projects
Authors: Cho Yongsung
Published: May 2021

The article examines restricting factors in international cooperation, drawing a comparative analysis of two cases on cross-border infrastructure projects: the Gyeongui railway line that connects North and South Korea and the Kars-Gyumri-Tbilisi railway line that links Turkey and Armenia. In both cases, states involved strive for the normalization of diplomatic relations and border openness as well as potential economic opportunities and national security. Nevertheless, neither Seoul and Pyongyang nor Ankara and Yerevan succeeded in building a sustainable cooperation framework. While the outcome is the same, independent variables in both cases are different. Firstly, two Koreas have been in a military confrontation for seven decades, whereas Turkey and Armenia never engaged in a direct conflict. Secondly, the configuration of alliances (South Korea and the United States and Turkey and Azerbaijan) weakens the decision-making on the troublesome infrastructure projects. Consequently, alliances are identified as one the key factors that determine the mode of international cooperation.
Internationalization of Renminbi as a Function of China’s Foreign Exchange Policy
Authors: Chernilevskaya Klavdiya E.
Published: May 2021

This article discusses the prospects of the Chinese renminbi (RMB) to expand its sphere of influence and become a full-scale reserve world currency. The methods used in the article are retrospective analysis and graphic analysis. The work is divided into three sections. The first section provides a broad overview of modern reserve currencies. The second part characterizes RMBs shaping as a reserve currency, as well as inner and outer factors that influence its status. The third section includes information about RMBs current status and its perspectives for being a reserve currency in the future. The article argues that currently RMB has already become a regional reserve currency in Asia-Pacific. Chinese government continues to make steps towards international expansion of RMB, yet these steps cannot make RMB one of the leading world currencies together with USD and EUR in the nearest decade.
The Сoncept of Сyber Sovereignty of the People’s Republic of China: Development History and Essence
Authors: Mikhalevich Ekaterina A.
Published: May 2021

The transformation of cyber sovereignty into an independent concept is a recent phenomenon, and thus its development and distribution is currently underway, which indicates the relevance of studying this topic. Being one of the most influential actors of contemporary international politics, China uses the concept of cyber sovereignty to promote its national interests and is able to shape the rules in the highly volatile field of international cyberspace. The study is based on quantitative and qualitative content analysis of legal acts and concept of Chinas cyber sovereignty. The author defines a concept of cyber sovereignty and identifies its place in the system of international law and in the architecture of international information security. Chinas concept of cyber sovereignty does not imply the division of a common cyberspace into separate segments but contributes to the creation of a cyber community of a common destiny, in which states can exercise their rights to govern the Internet on the principles of equality, justice, cooperation, peace and rule of law. It is concluded that this concept can be used as the basis for the formation of an international legal framework that regulates relations between states in the field of cyberspace.

Published: May 2021

The perspectives of modern South Korean youth on Russia and perspectives of Russian youth on South Korea respectively are reconstructed and interpreted in this article. The research was conducted on the basis of analysis of 100 in-depth interviews with Russian and South Korean student youth (50 students in each group), specializing in Russian-Korean relations, intercultural communications and language of the country studied. Natural and geographic factors, historical and cultural associations, the image of the countrys citizens are found to be the main South Korean students perspectives on Russia. Economic system, the image of the countrys citizens, historical and cultural features of the country represent the main Russian students perspectives on South Korea. In general, mutual images of each country contain many stereotypes which are mediocre for common perception. Such stereotypical thinking and the lack of knowledge about modern socio-economic realities among future specialists in Russian-Korean relations may be a serious obstacle that places under risk effectiveness of further cooperation between the two sides.
The impact of audit committee financial expertise on corporate financial decisions
Authors: Al Lawati Hidaya , Hussainey Khaled
Published: May 2021

Audit committee (AC) financial experts is considered one of the important corporate governance mechanisms due to their vital role in overseeing companies’ financial reporting procedures and enhancing corporate financial decisions. Regulators and policymakers require Omani firms to have at least one director with financial expertise sitting on ACs. Therefore, we aim to investigate the effect of AC financial expertise on corporate financial decisions (capital structure, dividend payment and cash holdings). We use a data set of all Omani financial institutions (36 firms) listed on the Muscat Stock Exchange (MSX) over the period from 2014 to 2019, consisting of 216 firm-year observations. The paper contributes to the growing body of the literature by being the first study to examine the impact of AC financial expertise on financial decisions. The study also contributes to the literature by integrating multiple theories: agency, resource dependence and signalling, to enlighten the effect of the unique power of financial expertise on making financial decisions. We find that AC members with financial expertise are positively related to the level of cash holdings, leverage and dividend payment in financial companies. The findings provide empirical evidence to regulators to encourage companies to exceedingly appoint financial experts as AC members due to their unique resources, which improve their monitoring role and constraining management opportunistic behaviour

Meticulous transfer of coronary arteries is of crucial importance in
transposition of great arteries and determines the success of the switch
procedure. This report describes a coronary anatomy consisting of four
separate ostia from the two facing sinuses in a six-month-old infant
presenting with d-transposition of great arteries and ventricular septal
defect. Being a rare coronary arterial pattern not described in previous
coding systems, the surgeon would do well to be aware of this
possibility while performing the switch procedure.
Controllo dei composti organici volatici mediante fotobioreattore algale-batterico
Authors: Budetti Carmine Antonio
Published: May 2021

Oggigiorno si è continuamente esposti a sostanze potenzialmente tossiche
per la salute, come nel caso dei composti organici volatili (COV); in
questo lavoro sono state individuate le origini di queste sostanze, i
possibili danni derivati dall’esposizione con esse, oltre ad alcune
tipologie di trattamento per il loro abbattimento. Ci si è soprattutto
soffermati sul confronto tra una tecnologia biologica convenzionale, con
filtro biotrickling (BTF) ed una innovativa, rappresentata da un
fotobioreattore tubolare algale-batterico (TPBR), prendendo in esame
l’abbattimento del toluene, uno dei COV più diffusi, appartenente alla
famiglia dei BTEX. Il TPBR ha mostrato efficienze medie di rimozione del
toluene vicine a quelle del BTF ma è risultato più stabile, a differenza
di quest’ultimo che risulta influenzato dalla presenza di metaboliti
secondari.
