Change, adaptation and culture: Media communication in pandemic times
Authors: Rahman Khairiah A
Published: July 2022

Commentary: Global lockdowns and border closures during the COVID-19 pandemic has meant that educational institutions and international conferences have taken on a virtual existence for more than two years. Uncertainties surrounding the pandemic and the enormity of its impact became a focal point of academic scrutiny for communication sciences and media research. Themes from the Asian Congress for Media and Communication Conference 2021 (ACMC2021) centred around change, adaptation and culture in pandemic times with 12 streams including democracy and disinformation, media influence and impact, and climate change in the Asia-Pacific. This commentary presents an overview of the conference and introduces four of the presentations delivered at the ACMC2021; two keynotes and two paper presentations. The keynotes discussed information challenges such as control on social media, truth, hate rhetoric and the climate emergency in the Asia-Pacific region, while the papers focused on practitioner perceptions and the role of a higher order in securing media freedom and fair representation.
Methods of calculating influence of seasonality factor on propagation of radio waves in southern regions of Russia close to hydrospheric objects in ultra-high frequency range
Authors: Pishchin Oleg Nickolaevich , Puzankov Dmitriy Sergeevich , Liydkina Kseniya Sergeevna
Published: July 2022

The article substantiates the assertion that for radio communication design areas in the territory close to the hydrospheric objects (rivers, lakes, sea areas) it is necessary to use calculation methods taking into account the difference in the level of signal attenuation due to seasonality. This is especially true for the Astrakhan region characterized by hot summers (to which it is advisable to add the last month of spring - May - and the first month of autumn - September, also characterized by high air temperatures). Seasonal features of radio wave propagation are determined by the continuous superrefraction above the water part of the radio line, which is formed due to the temperature inversion during the whole period of hot weather in the Astrakhan region. This is a fairly long period of time (at least 5 months a year) that must be taken into account in design systems to obtain an accurate picture of the signal level distribution in the ultra-high frequency range for such systems as television and radio broadcasting systems, cellular communication systems. Upon the results of the research and field tests it has been inferred that the effect of ultra-long-range propagation of radio waves in a tropospheric waveguide does not depend on the frequency range of the radiating system. A new method for calculating the attenuation of radio signals over the water surface in the near-water tropospheric waveguide has been developed.
EFFECTS OF THE SOCIOPOLITICAL CONTEXT ON SAINT AUGUSTINE’S THEOLOGY
Authors: ANDRÁS Szabolcs
Published: July 2022

The present study aims to explore the sociopolitical background of Augustine’s theology by way of analysing three of his letters. Augustine’s letters contain a number of elements that contribute to our understanding how changes in the social conditions influenced the bishop’s views concerning issues such as free will, sin, or freedom. In addition, we can also observe that Augustine was preoccupied with social issues still relevant today such as migration, taking care of refugees, death sentence, or the relationship between state power and freedom.
El impacto de los gastos de campaña en la elección presidencial de 2006 en México: una aproximación
Authors: Fonseca Felipe J.
Published: July 2022

Con datos a nivel de los 300 distritos electorales del país se analiza el impacto de los gastos de campaña en la elección presidencial de 2006. Debido a la falta de información, se realiza una aproximación a través de las erogaciones realizadas en las campañas para Diputados Federales. Entre los resultados principales destacan que el candidato del PAN tuvo una mayor rentabilidad electoral de sus gastos de campaña, sobre todo en el rubro de medios audiovisuales; mientras que, para el candidato del PRD, los gastos operativos de campaña resultaron más efectivos. Al considerar su efecto estratégico estático, los gastos del PAN restaron votos al candidato del PRD, pero no se encontró evidencia estadística del efecto contrario. Se obtiene evidencia de una baja rentabilidad electoral por parte del candidato del PRI, así como efectos estratégicos de los gastos de los partidos Nueva Alianza y Alternativa Socialdemócrata sobre los principales contendientes.
Coordination between environment, poverty, and SDGs through a carbon tax
Authors: Ortega Díaz Araceli , Guevara Zeus , Chapa Cantú Joana
Published: July 2022

Since 2014, Mexico has implemented a carbon tax policy, which has not reached the expected revenue, failed at decreasing emissions, and had a regressive effect. Moreover, there has not been coordination between climate and other Sustainable Development Goals (SDGs). To explore this, we perform a Computable General Equilibrium analysis to simulate a coordinated carbon tax policy aimed at reaching the SDGs goals related to poverty, mortality, and education. The results suggest that the required carbon tax rate for approaching SDGs targets by 2030 should be around 15%, which is higher than the actual rate and may cause other distortionary effects.
Geschickt koordinierender Pluralismus oder disharmonisches Prinzip der Nichteinmischung?
Authors: Leuppi Christoph
Published: July 2022

This article addresses the question of how the plurality of actors and subjects in Swiss China policy at the executive level affects the coherence of foreign policy towards China at the strategic policy level. The analysis is based on a legal and qualitative examination of the institutional foundations, evaluates the content of the relevant strategy papers and primary sources from the federal administration, while qualitative interviews allow it to be contextualized in the area of China policy. The results show that the legal basis favors the plurality of actors in Swiss China policy and thus the independence of the actors, which means that interdepartmental cooperation and the constellation of parties and persons in the Federal Council play an important role. Together with the vague overall strategic concept of the Federal Constitution, this ultimately promotes the emergence of intentional incoherence in the sense of different China policies within the federal executive.

Authors: Ren Li , Huang Wenquan , Kodakkadan Yoonusraj , Lakys Yahya
Published: July 2022

This article proposes a resonance suppression method for a flexible load servo drive system based on a flexible manipulator's pose transformation. We establish a flexible load servo drive system for the robotic arm based on the continuum vibration theory and the transfer function estimation method. The controller consists of two parts: compensation control and dynamic feedback. The transfer function of the active feedback part is strictly positive and real. At the end of the thesis, the asymptotic stability of the closed-loop system in the neighborhood of the desired position is proved through the linear operator semigroup theory and the LaSalle invariant set principle.

Published: July 2022

It is more difficult to give Laplace transform directly in a defined form or derive it by Fourier transform in mathematics teaching. The article gives a solution for solving high exponential series sum by using Laplace transform. With the help of Laplace transform, calculus operations can be transformed into complex plane algebra operations. The application of the algorithm to the option hedging strategy verifies the applicability of the algorithm proposed in this article.

Authors: Jabr Hakima Salman , Ali Rajaa Hussein Abd
Published: July 2022

The present research focuses on a theoretical study of structural and electronic properties of pure graphene sheet and then adding different number of N2 atoms. The calculations are carried out using the density functional theory (DFT) with hybrid functional B3LYP/6-31G level to investigate the proposed structures. Gauss View 5.0.8 program is used to design the structures of pure and doped graphene sheets. These structures are relaxed by employing the PM6 semi-empirical method with the hybrid functional B3LYPDFT at Gaussian 09 package. The results of the structural properties of the studied graphene sheets showed that good relaxation of the structures, the constant bonds values in the pure graphene sheets in the same ranges of the carbon rings structures. We calculate the total energy, High Occupied Molecular Orbital (HOMO) and Low Unoccupied Molecular Orbital (LUMO) energies and forbidden energy gap. The result of the total energy of that doping graphene sheets is result of the binding energy of each structure and indicates that these structures have relaxation, and the effect of adding N2 atoms in pure graphene sheet on the total energy of the molecule is effective. All doping graphene sheets have small forbidden energy gap, but it vibrates depending on the length and number of each sheet and the position of N2 atoms in the sheets.
New data on the presence of the Blotched snake (Elaphe sauromates Pallas, 1814) in the region of Shumen town (Bulgaria), with emphasis on the negative human attitude toward the species

Published: July 2022

In the present study, we report on new localities in Northeastern Bulgaria, where Elaphe sauromates (Pallas, 1814) was recently detected. We registered five Blotched snakes in the region of Shumen town in the period 2018 - 2022. All of the snakes were adults, three were killed by tools impacts and two of them were road kills. To date, the Blotched snake was registered extremely rare and in rather long intervals (of several decades) in the region of Shumen. Our findings indicate that the species currently inhabits the suburban and urban territories near the villages of Ivanski, Radko Dimitrievo and Konyovets. Two of the locations are new for the 10 km grid-system used for standard monitoring of the biodiversity in Bulgaria.
Dynamics of CTAB micelle mediated reaction of fuchsin degradation in alkaline medium
Authors: Latona Dayo Felix , Akinola Emmanuel Adegoke
Published: July 2022

Cetyltrimethylammonium bromide (CTAB) micelles catalyzed the degradation of fuchsin in the entire surfactant concentration range investigated. The pseudo first order rate constants increased with CTAB concentrations. However, there was a decrease in the rate constant at higher concentrations of CTAB. Increase in the rate constant was attributed to the incorporation of fuchsin and hydroxide ion in the stern layer of the CTAB micelles. The kinetics involved the removal of the π-conjugation in fuchsin due to its attack by hydroxide ion on the central C atom of the planar ring which led to the formation of carbinol. The reaction showed first order each to fuchsin and OH-. Menger-Portnoy and Piszkiewicz cooperative models were used to explain the micellar and kinetic effects.

From an economic point of view, for all production costs, it is recommended to plan these costs, taking into account the costs necessary for equipment maintenance activities. The maintenance strategies that the company performs must follow certain standards, taking into account the maintenance policy that guides them and the chosen maintenance methods. Depending on the type of maintenance used in the factories, they can have a positive or negative impact on the company’s economy, caused by certain factors.
Effects of linagliptin on morphine dependence in larval zebrafish (Danio rerio)
Authors: Lupina Malgorzata , Listos Joanna
Published: July 2022

Drug addiction is a chronic, recurrent disease of the central nervous system that leads to the development of comorbidities and premature death. Despite extensive scientific research concerning addiction, no effective method of addiction pharmacotherapy has been known so far. Glucagon-like peptide 1 has been suggested to play a role in the rewarding effect of addictive drugs. Linagliptin is a selective dipeptidyl peptidase-4 inhibitor that suppresses the rapid degradation of endogenous glucagon-like peptide-1. In clinical practice, it is used as an antidiabetic drug, but recent studies have confirmed its role in the activity of the central nervous system. This pilot study was conducted to ascertain whether linagliptin might influence morphine dependence – a locomotor activity test was carried out to assess the intensity of morphine withdrawal symptom. The obtained results clearly confirmed that linagliptin (0.01 and 0.1 mM) reduced the locomotor activity in morphine-dependent larval zebrafish. The undertaken experiments clearly indicates that linagliptin is involved in the addictive effects of morphine, thus, further studies on higher organisms should be carried out.

Published: July 2022

The growing increase in oral cavity cancer (OSCC) incidence constitutes a severe diagnostic-therapeutic problem – and early diagnosis, as well as medical treatment remain important priorities of maxillofacial oncology. The aim of this paper was to determine the reasons for delays in the diagnostics and treatment of oral cavity cancer patients. The study focused on 248 patients (=56.1 years) post-surgery, in which delays in diagnostics and treatment were reported. As for the causes, most frequently, in 171 cases (69.0%), patient delays were reported, in 56 cases, physician delays were observed, and in 21 cases (8.5%), organizational reasons were to blame. The median time period between the onset of the symptoms and seeking medical attention was 143 days. Time interval between the first contact with a doctor and commencement of oncological treatment was 33.2 days approximately. The majority of the patients were not aware of the oral cavity cancer risk. Misdiagnosis of symptoms as inflammation, as well as prolonged antibiotic therapy and diagnostics constitute main reasons for physician and organization-al/health care system delays. Raising patients’ awareness of cancer risk, as well as educational and promotional programs for physicians are the principal goals of a strategy aiming to enhance oral cancer diagnosis.

Published: July 2022

In preclinical studies, simple coumarins (scoparone, limettin) and furanocoumarins (imperatorin, xanthotoxin, bergapten) have already found to demonstrate procognitive abilities. This suggests that they hold antioxidative, anti-inflammatory and inhibitory action towards acetylcholinesterase activities. However, little is known about their influence on the amyloidal structure formation, the leading cause of Alzheimer’s disease (AD). In vitro and in cellulo assays were applied to evaluate the effect of selected coumarins on the different stages of Aβ40/42 and tau protein aggregation. Kinetic analyses were performed to evaluate their inhibiting abilities in time. Limettin revealed the most potent inhibiting profile towards Aβ40 aggregation, however, all tested compounds presented low influence on Aβ42 and tau protein aggregation inhibition. Despite the preliminary stage of the project, the promising effects of coumarins on Aβ40 aggregation were shown. This suggests the coumarin scaffold can serve as a potential multitarget agent in AD treatment, but further studies are required to confirm this.
The role of appetite-controlling hormones in the development of eating disorders in diabetic 2 patients
Authors: Urbanovych Alina , Laniush Fedir
Published: July 2022

Binge eating disorder (BED) and night eating syndrome (NES) are common eating disorders (EDs) in individuals with diabetes type 2 (DT2). They worsen metabolic control, have a negative impact on physical and mental health and reduce quality of life. The roles of appetite-controlling hormones – leptin and ghrelin – is not clear enough in EDs and need to be investigated in order to establish new approaches and markers of EDs. Aim: To assess the difference in leptin and ghrelin levels in DT2 patients with and without EDs. 57 patients with DT2 were involved in the study. After physical examination and screening for EDs, blood samples for leptin and ghrelin measuring were obtained.

Results: 19 participants (33.3%) were screened positively for ED (BE or NES). Leptin levels were higher in participants with ED (p<0.05). Conversely, ghrelin levels were lower in those with BE or NES (p<0.05).

Leptin level is increased in DT2 individuals with BED and NES, whereas ghrelin is decreased. Leptin and ghrelin alterations maintain emotional eating, increase the frequency of binge and night eating episodes. In screening for EDs, assessing leptin and ghrelin levels will facilitate obesity reduction and improve metabolic control in diabetic patients.
Laser Powder Bed Fusion and Selective Laser Melted Components Investigated with Highly Penetrating Radiation

Published: July 2022

Methods of incremental manufacturing, i.e. 3D printing, have been experiencing significant growth in recent years, both in terms of the development of modern technologies dedicated to various applications, and in terms of optimizing the parameters of the process itself so as to ensure the desired mechanical and strength properties of the parts produced in this way. High hopes are currently being pinned on the use of highly penetrating types of radiation, i.e. synchrotron and/or neutron radiation, for quantitative identification of parameters characterizing objects produced by means of 3D printing. Thanks to diffraction methodologies, it is feasible to obtain input information to optimize 3D printing procedures not only for finished prints but also to monitor in situ printing processes. Thanks to these methodologies, it is possible to obtain information on parameters that are critical from the perspective of application of such obtained elements as stresses generated during the printing procedure itself as well as residual stresses after printing. This parameter, from the point of view of tensile strength, compression strength as well as fatigue strength, is crucial and determines the possibility of introducing elements produced by incremental methods into widespread industrial use.

The focus of this research work was predicting the fatigue life of mechanical components used for industrial and transport systems. To understand how the phenomenon of fatigue occurs in a material, the fatigue crack growth is studied. The purpose of this work was to create a graphical user interface (GUI) under Matlab to allow researchers to conduct the parametric studies of fatigue crack propagation to predict fatigue life. In this work, three models for fatigue crack propagation were used: those of Paris, Walker and Forman in order to study the three parameters: the Paris exponent m, load ratio R and hardness K

, respectively. In addition, a novel model FCG was developed to study the influence of the hardening parameters (K′, n′) on fatigue crack propagation. The comparison of the simulation results with those in the literature shows good agreement.
Reliability and Utility of Standard Gene Sequence Barcodes for the Identification and Differentiation of Cyst Nematodes of the Genus Heterodera
Authors: Huston Daniel C. , Khudhir Manda , Hodda Mike
Published: July 2022

Difficulties inherent in the morphological identification of cyst nematodes of the genus Heterodera Schmidt, 1871, an important lineage of plant parasites, has led to broad adoption of molecular methods for diagnosing and differentiating species. The pool of publicly available sequence data has grown significantly over the past few decades, and over half of all known species of Heterodera have been characterized using one or more molecular markers commonly employed in DNA barcoding (18S, internal transcribed spacer [ITS], 28S, coxI). But how reliable are these data and how useful are these four markers for differentiating species? We downloaded all 18S, ITS, 28S, and coxI gene sequences available on the National Center for Biotechnology Information (NCBI) database, GenBank, for all species of Heterodera for which data were available. Using a combination of sequence comparison and tree-based phylogenetic methods, we evaluated this dataset for erroneous or otherwise problematic sequences and examined the utility of each molecular marker for the delineation of species. Although we find the rate of obviously erroneous sequences to be low, all four molecular markers failed to differentiate between at least one species pair. Our results suggest that while a combination of multiple markers is best for species identification, the coxI marker shows the most utility for species differentiation and should be favored over 18S, ITS, and 28S, where resources are limited. Presently, less than half the valid species of Heterodera have a sequence of coxI available, and only a third have more than one sequence of this marker.
First report of Longidorus leptocephalus Hooper, 1961 (Nematoda: Longidoridae) from Greece

Published: July 2022

Longidorid nematodes comprise more than 500 species, and Longidorus and Xiphinema are the most diversified, prevalent, and cosmopolitan genera within plant-parasitic nematodes. The genus Longidorus comprise a group of species, some of which are vectors of plant viruses. New sampling for needle nematodes was carried out in a grapevine area in Thessaloniki, northern Greece, and one nematode species of Longidorus (L. leptocephalus) was recovered. Nematodes were extracted from soil samples by modified sieving and a decanting method. Extracted specimens were processed using glycerol, mounted on permanent slides, and subsequently identified morphologically. Nematode DNA was extracted from individual, live specimens, and PCR (Polymerase Chain Reaction) assays were performed for D2-D3 expansion segments of 28S rRNA, ITS1 rRNA, and partial mitochondrial COI regions. Morphology and morphometric data obtained from this population were consistent with the original description and reported populations of L. leptocephalus. To our knowledge, this is the first report of L. leptocephalus in Greece and the second in the Mediterranean Basin after the record of the species from Slovenia, extending the geographical distribution of this species in Europe.
Application of therapeutic linear accelerators for the production of radioisotopes used in nuclear medicine
Authors: Konefał Adam , Orlef Andrzej , Sokół Maria
Published: July 2022

This review paper summarizes the possibilities of the use of therapeutic linear electron accelerators for the production of radioisotopes for nuclear medicine. This work is based on our published results and the thematically similar papers by other authors, directly related to five medical radioisotopes as 99Mo/99mTc, 198Au, 186Re, 188Re, 117mSn, produced using therapeutic linacs. Our unpublished data relating to the issues discussed have also been used here. In the experiments, two types of radiation were included in the analysis of the radioisotope production process, i.e. the therapeutic twenty-megavolt (20 MV) X-rays generated by Varian linacs and neutron radiation contaminating the therapeutic beam. Thus, the debated radioisotopes are produced in the photonuclear reactions and in the neutron ones. Linear therapeutic accelerators do not allow the production of radioisotopes with high specific activities, but the massive targets can be used instead. Thus, the amount of the produced radioisotopes may be increased. Apart from linear accelerators, more and more often, the production of radioisotopes is carried out in small medical cyclotrons. More such cyclotrons are developed, built, and sold commercially than for scientific research. The radioisotopes produced with the use of therapeutic linacs or cyclotrons can be successfully applied in various laboratory tests and in research.
PCM Modified Gypsum Hempcrete with Increased Heat Capacity for Nearly Zero Energy Buildings
Authors: Bumanis Girts , Bajare Diana
Published: July 2022

Low energy building materials based on natural and renewable resources have become popular among customers. The natural occurrence of the raw materials and the idea to move closer to nature with its natural products have brought high interest in hempcrete. Hempcrete is a kind of binder-aggregate material where besides mineral binder, hemp shive aggregate act as a filler. A good technical performance of such composites has been reported before, while the term an ‘advanced material’ for traditional hempcrete lacks some superior properties for civil engineers. This research offers advanced hempcrete-type material where gypsum binder and hemp shives are used as the main components. Additionally, phase change material (PCM) was incorporated into the mixture composition to increase their thermal mass. PCM gives additional thermal heat storage for buildings which makes the building envelope more homogenous regarding thermal stability under outer temperature fluctuations. This could give additional comfort during heating and cooling seasons. Up to 20 wt.% of microencapsulated PCM suspension had been added to the hempcrete mixture composition and heat capacity was calculated and validated with differential scanning calorimetry measurements. Physical and mechanical performance was also evaluated. Results indicate that in the temperature interval from 20 to 30 °C, the heat capacity of hempcrete can be increased to 1901 J/(gK) (by 70.4 %) and it correlates well with theoretical thermal mass calculation. This gives promising results for further development of the material and proves the feasibility of PCM integration in hempcrete.

Authors: Uzelac Bojana , Mrdović Igor , Kašćak Jelena
Published: July 2022

Electromechanical association is a very unique physiological type of ECG artifact caused by the radial artery pulse tapping. ECG presentation of this artifact may imitate primary repolarization changes characteristic for acute coronary syndrome or electrolyte abnormalities. The peculiarity of electromechanical association is the synchronization with regular cardiac cycles, making a diagnostic challenge even for experience physicians. The present case is a rare example of an ECG artifact localized in a specific pattern mimics ECG changes of acute myocardial infarction with ST elevation (STEMI), including reciprocal ST depression. Moreover, serial prehospital ECGs verify evolution from hyperacute T waves to true ST elevation, as we seen in acute myocardial infarction. The key for artefact recognition was the knowledge about ECG leads derivation and identification the affected electrode. Electromechanical association frequency is unknown: it may be common, but often unrecognized finding. So far, electromechanical association in serial ECGs wasn’t reported, as per our knowledge.
Freeing the “Captive Rider”
Authors: Prayitno Khairunnabila , Moos Markus
Published: July 2022

In recent years, public transit policy has often focused on chasing ‘choice’ riders, or those who have mode alternatives, while taking for granted ‘captive’ riders, or also referred to as transit dependents. This paper argues for a need to re-centre attention towards ‘captive’ riders through equity and sustainability perspectives, and to question the use of the term ‘captive’, as it alludes to marginalization. We conduct this research by examining the transit experiences of a sample of young captive riders in Don Valley Village and Crescent Town, two high-rise suburban neighbourhoods in the City of Toronto. Semi-structured interviews are used to gain insight into participants’ travel patterns and the challenges associated with public transit use. Participants accrue different types of costs with their experiences (i.e., time, money, safety, and comfort), which do limit their ability to participate in public life. The study is situated in the broader context of transit equity, which point to the need for service quality improvements for ‘captive’ riders. This study also shows why assessments of young captive riders’ experiences is essential for planning. Contrary to how captive riders are perceived, service quality issues prompted some of the study participants to switch to driving, which further questions the categorization of ‘choice’ and ‘captive’. Transit agencies are urged to consider further how to improve transit quality for ‘captive’ riders to contribute to equity but also to maintain transit loyalty among younger transit riders as their circumstances change.

Cláusulas dependientes y organización discursiva en quichua santiagueño
Authors: Juanatey Mayra
Published: July 2022

Uno de los factores que puede afectar la accesibilidad de los referentes en el discurso es la existencia de rupturas de unidades discursivas. Estas pueden motivar la elección de formas lingüísticas de alta explicitud o de recursos discursivos que colaboran en el seguimiento referencial. Este trabajo se centra en la observación de los límites entre unidades textuales en quichua santiagueño (quechua, Argentina) y las consecuencias en la expresión de referentes y su seguimiento en el discurso. Para este estudio se conformó un corpus de textos en quichua santiagueño de fuentes primarias y secundarias, que fueron segmentados y analizados en secciones, según el desarrollo del tópico narrativo. Se logró identificar así que los diferentes tipos de cláusulas dependientes (relativas y adverbiales) funcionan como guías del flujo de la información, especialmente cuando están presentes en transiciones de una porción de texto a otra.
Salutations verbales
Authors: Mestre de Caro Maria Del Pilar
Published: July 2022

Les salutations verbales expriment la politesse et la bienveillance envers l’interlocuteur au moment d’entamer ou de clore une conversation. Bien qu’elles soient apprises dès la petite enfance, dans le cas de la langue maternelle, ou dès les premiers niveaux de l’étude des langues étrangères, l’intériorisation de leur emploi ne se limite pas à un simple apprentissage des routines verbales.
Bien au contraire, la maîtrise de ces actes de langage implique la prise en compte de variables indépendantes comme l’âge, le sexe, le niveau socio-économique et éducatif de l’interlocuteur, ainsi que le degré de formalité de la situation de communication. Ces facteurs jouent un rôle essentiel dans la compréhension et la sélection de ces mots. Pour mieux comprendre la problématique, cet article propose de parcourir une brève sélection de travaux portant sur l’origine, l’évolution et la pragmatique des salutations (approches diachroniques et synchroniques).
À partir de la littérature du savoir-vivre et des études ethnographiques, sociolinguistiques et interactionnistes, nous cherchons à adopter une approche théorique pertinente pour saisir le fonctionnement des salutations en contexte, principalement en français. Dans un deuxième temps, nous analysons deux corpus linguistiques authentiques et un dialogue cinématographique, où l’on observe que les maladresses dans l’emploi des salutations ou des termes d’adresse peuvent être à l’origine des malentendus communicationnels.
Nous tenons donc compte ici des variables pragmatiques des salutations, des termes et des pronoms d’adresse, afin de formuler quelques remarques explicatives qui peuvent s’avérer utiles aux enseignants, ainsi qu’aux apprenants de FLE.
Open-access publishing: Boon or bane for Indian medical researchers?
Authors: Dhiman Vikas , Tiwari Rajnarayan Ramshankar
Published: July 2022

The concept of Open-Access (OA) publishing was initiated in the early 2000s with the idea to provide free, equal, and OA of scientific knowledge to all communities and countries. The article published in an OA journal is freely available on the public internet and permits any users to read, download, copy, distribute, and print. The OA articles are published much sooner and are believed to get more citations than the articles published in subscription-based journals. Since the end-user does not have to pay to read an OA article, the author usually pays Article Processing Charges (APCs) to get his/her work published in OA journals. High APCs of OA journals are usually a serious concern for medical researchers in India, which restricts them to publish in OA journals. Since most OA journals are new, they tend to have low impact factors as compared to subscription-based journals, which prevent many good researchers to get their work published in OA journals. Furthermore, predatory journals exploit the idea of OA and tend to publish poor or very low-quality research papers. This has resulted in distrust among the authors and readers that OA publishing is not peer-reviewed or has low quality. In conclusion, publishing in OA journals has both pros and cons. With the Government of India’s ambitious “One Nation, One Subscription” policy in the pipeline, medical researchers in India are hopeful that soon both access and publishing in scientific journals will be free for all in the country.

In addition to his stellar scientific career, Prof. Yuval Ne'eman devoted many years to public service. At the beginning of the 1980s, Ne'eman joined the political arena, through which he sought to actualize his ideological beliefs, such as by helping to establish dozens of Jewish settlements in Juda and Samaria. This article explores his contribution to the advancement of archeological research in Judea and Samaria, which stemmed from his desire to strengthen Israel's ties to this patrimony. Recentlyreleased archival files reveal his substantial behind-the-scenes activity in this field. He established and headed the Israel Ministry of Science and Development, which carried out surveys and excavations in peripheral areas, particularly in Judea and Samaria. His decisive contribution resulted in an unprecedented research drive in this region. Governmental backing, public support, and prevailing calm in terms of security, encouraged senior Israeli archeologists to participate in archeological research over the Green Line, although they could have done so for the preceding 15 years. The result was a golden age of archeology in Judea and Samaria, which has not recurred up to the present day (2021).

The Gulf Cooperation Council and the Eurasian Economic Union: opportunities and prospects of trade cooperation
Authors: Prokopiev P. S.
Published: July 2022

The article discusses the possibilities of developing trade cooperation between the Eurasian Economic Union and the Cooperation Council for the Arab States of the Gulf. The purpose of the work is to identify and analyse specific sectors of the economy that may offer potential interest in the event of the creation of a free trade zone between integration associations. As a result of the study, potential opportunities for trade and economic cooperation in the agro-industrial complex were identified. The methods of analysis and comparison of data from information and analytical materials on the advantages and trends of foreign trade relations of the EAEU and GCC countries were used. The state of the matter at the political level is indicated, as well as the main barriers and potential risks to the growth of trade. The relevance of the work lies in the need to diversify foreign trade partners and ensure the sustainability of economic growth for the integration associations under consideration in the conditions of macroeconomic turbulence, global disruption of supply chains and the general degree of high tension in international economic relations.
The conflict potential of Petrine bureaucracy reform in the mirror of post-Petrine “epoch of palace coups”
Authors: Znamenskiy D. Yu.
Published: July 2022

The article considers the reform of the civil service in Russia 1716–1722, and it’s influence on the social processes of post-Peter Russia. The author pays particular attention to the conflict potential of the transformations carried out by Peter I in public service, thereby the most acute conflicts caused by the reforms are distinguished, and their classification and analysis of factors that directly influenced their development are given. The author interprets the events of the first fifth anniversary of the «era of palace coups» in terms of conflict science, analyses the conflicting parties social composition, the logic of their actions, the socio- political results of the confrontation. The initial value gap between the “old” and “new” bureaucracy and a number of problems, have not been solved in the reign of Peter I, are highlighted as key conflict triggers.
Strategic issues of raising international financing
Authors: Tarasov A. A.
Published: July 2022

The article discusses some strategic issues related to the raising of international financing by the means of syndicated loans and eurobonds by Russian corporations. Author proposes a method for benchmarking the financial position of the company compared to its competitors. This analysis uses key performance indicators, including the debtfinancing share, credit rating, weighted average cost of capital. Crises have become a frequent occurrence in global economy. For the top-managers of the corporation, one of the key tasks during the period of economic uncertainty is the handling of communications with lenders and investors for the control of the company’s financial position. The article considers the specifics of providing the required information about company activity during the crisis. The key document is the financial model, based on the macroeconomic, industrial, and operational assumptions regarding the borrower’s operations. Using financial covenants as an example, we consider the mechanics of incorporating changes into the current loan terms, as well as the raising of new funding by using shirt-term revolving credit facilities. For the solution of one of the key strategic goals of corporate finance – execution of mergers and acquisitions transactions – we present an algorithm of raising financing by using syndicated loans and eurobonds.
Synergic value effect from subscription to services within the Yandex ecosystem
Authors: Akhmaeva L. G.
Published: July 2022

This article examines the creation and development of ecosystems in business in the Russian market. The author analyses the concept of “ecosystem” as it applies to business and describes the main ways in which the first ecosystems to emerge in the Russian market have been formed. The review and analysis of service accession to the Yandex ecosystem is carried out, and brief characteristics of its key services are given. Two main elements of any ecosystem, including Yandex, are highlighted for the user: subscription and a single user identifier (ID). Their impact on consumer behaviour and the synergistic value effect of subscriptions to services within the Yandex ecosystem for its users is described. The most effective way of attracting users to ecosystem loyalty programmes – product delivery – is highlighted and its advantages are shown. The issue of building a new ecosystem in business, comparable in scale to Yandex, is raised, and attract enough users. For this, businesses must develop and offer a unique service to the user or a unique experience different from what is currently available. Recommendations for entrepreneurs and forecasts for the further development of ecosystems in Russia are given.
Theoretical and methodological approaches to the study of interregional interactions in ensuring economic security
Authors: Averina L. M. , Nikulina N. L. , Naumov I. V.
Published: July 2022

The adoption of strategies for the spatial development of the Russian Federation, national and economic security has brought the study of inter-regional interactions up to date. In this regard, the authors have reviewed the theoretical and methodological approaches of domestic and foreign scientists to the issues of interregional cooperation in various branches of science and production. Interpretations of the concepts “inter-regional interaction”, “economic security” and “economic security of the region” are analysed. The role of inter-regional cooperation, especially inter-regional investment projects, as critical factors in ensuring regional economic security is emphasised. Groups of potential risks and risk-forming factors for joint inter-regional infrastructure projects are identified. Interregional projects are classified according to their scope and purpose: 1) in the production sphere; 2) projects promoting innovation; 3) projects aiming at infrastructure development. Examples of existing interregional projects in the Ural Federal District are presented. The study uses general scientific methods, in particular, analysis and synthesis. The results of the study can serve as a basis for the further development of new theoretical and methodological approaches to solving the problems of inter-regional cooperation.
Supramolecular Semiconductivity through Emerging Ionic Gates in Ion-Nanoparticle Superlattices
Authors: Lionello Chiara , Perego Claudio , Gardin Andrea , Klajn Rafal , Pavan Giovanni M.
Published: July 2022

The self-assembly of nanoparticles driven by small molecules or ions may produce colloidal superlattices with properties reminiscent of those of metals or semiconductors. However, to what extent the properties of such supramolecular crystals actually resemble those of atomic materials often remains unclear. Here, we present coarse-grained molecular simulations explicitly demonstrating how a behavior evocative of that of semiconductors may emerge in a colloidal superlattice. As a case study, we focus on gold nanoparticles bearing positively charged groups that self-assemble into FCC crystals via mediation of citrate counterions. In silico ohmic experiments show how the dynamically diverse behavior of the ions in different superlattice domains allows the opening of conductive ionic gates above certain levels of applied electric fields. The observed binary conductive/non-conductive behavior is reminiscent of that of conventional semiconductors; however, at a supramolecular level, crossing the “band-gap” requires a sufficient electrostatic stimulus to break the electrostatic interactions and make ions diffuse throughout the superlattice’s cavities.
