Error rate control for classification rules in multiclass mixture models
Authors: Mary-Huard Tristan , Perduca Vittorio , Martin-Magniette Marie-Laure , Blanchard Gilles
Published: November 2021

In the context of finite mixture models one considers the problem of classifying as many observations as possible in the classes of interest while controlling the classification error rate in these same classes. Similar to what is done in the framework of statistical test theory, different type I and type II-like classification error rates can be defined, along with their associated optimal rules, where optimality is defined as minimizing type II error rate while controlling type I error rate at some nominal level. It is first shown that finding an optimal classification rule boils down to searching an optimal region in the observation space where to apply the classical Maximum A Posteriori (MAP) rule. Depending on the misclassification rate to be controlled, the shape of the optimal region is provided, along with a heuristic to compute the optimal classification rule in practice. In particular, a multiclass FDR-like optimal rule is defined and compared to the thresholded MAP rules that is used in most applications. It is shown on both simulated and real datasets that the FDR-like optimal rule may be significantly less conservative than the thresholded MAP rule.

Published: November 2021

Slurry polymerization processes using Zeigler–Natta catalysts are most widely used for the production of polyethylene due to their several advantages over other processes. Optimal operating conditions are required to obtain the maximum productivity of the polymer at minimal cost while ensuring operational safety in the slurry phase ethylene polymerization reactors. The main focus of this multi-objective optimization study is to obtain the optimal operating conditions corresponding to the maximization of productivity and yield at a minimal operating cost. The tuned reactor model has been optimized. The single objective optimization (SOO) and multi-objective optimization (MOO) problems are solved using non-dominating sorting genetic algorithm-II (NSGA-II). A complete range of Pareto optimal solutions are obtained to obtain the maximum productivity and polymer yield at different input costs.

Published: November 2021

Objectives

Adiposity rebound (AR) refers to an increase in body mass index (BMI) after a nadir. Early AR, in which AR occurs earlier than five years old, is a risk factor for future obesity and metabolic syndrome, but has not been widely studied in very-low-birth-weight infants (VLBWIs).

Methods

The subjects were VLBWIs born in Dokkyo Medical University NICU from January 2008 to December 2010. Height and weight measured at birth and at intervals until seven years old were obtained from medical records. The lowest BMI after one year of age was used for the age of AR. The subjects were divided into those with early and normal AR (<5 and ≥5 years old). BMI percentile at age seven years was compared using the interquartile range (IQR). Changes in BMI were evaluated by repeated measures analysis of variance (ANOVA).

Results

There were 38 early AR cases and 62 normal AR cases, giving a prevalence of early AR similar to that in infants with normal birth weight. BMI percentile at age seven years was significantly higher in early AR cases than in normal AR cases (44.6 [IQR: 21.0–79.2] vs. 14.4 [IQR: 3.8–40.8] kg/m2). Changes in BMI were also significantly higher in early AR cases (p=0.024 by ANOVA).

Conclusions

Early AR in VLBWIs is a predictor of future obesity.

Authors: Arattu Thodika Fahad M.S. , Nanjundappa Mahesh , Dassios Theodore , Bell Aaron , Greenough Anne
Published: November 2021

Objectives

Pulmonary hypertension (PH) is a complication of bronchopulmonary dysplasia (BPD) and associated with increased mortality and morbidity. Our aim was to identify, in infants with BPD, the effect of PH on health-care utilisation and health related cost of care.

Methods

An electronic data recording system was used to identify infants ≤32 weeks of gestation who developed BPD. PH was classified as early (≤28 days after birth) or late (>28 days after birth).

Results

In the study period, 182 infants developed BPD; 22 (12.1%) developed late PH. Development of late PH was associated with a lower gestational age [24.6 (23.9–26.9) weeks, p=0.001] and a greater need for positive pressure ventilation on day 28 after birth (100%) compared to infants without late PH (51.9%) (odds ratio (OR) 19.5, 95% CI: 2.6–148), p<0.001. Late PH was associated with increased mortality (36.4%) compared those who did not develop late PH (1.9%) after adjusting for gestational age and ventilation duration (OR: 26.9, 95% CI: 3.8–189.4), p<0.001. In infants who survived to discharge, late PH development was associated with a prolonged duration of stay [147 (118–189) days] compared to the infants that did not develop late PH [109 (85–149) days] (p=0.03 after adjusting for gestational age). Infants who had late PH had a higher cost of stay compared to infants with BPD who did not develop late PH (median £113,494 vs. £78,677, p=0.016 after adjusting for gestational age).

Conclusions

Development of late PH was associated with increased mortality, a prolonged duration of stay and higher healthcare cost.
The sociolinguistics of /l/ in Manchester
Authors: Turton Danielle , Baranowski Maciej
Published: November 2021

This paper presents a study of sociophonetic variation in the lateral approximant /l/ in Manchester, UK. We know little about how English laterals pattern sociolinguistically, despite them having been subject to extensive investigation in the phonetic literature. We present acoustic measures taken from interviews with 96 speakers from the city, stratified across five socioeconomic classes, spanning 99 years of birthdates (1907–2006). We demonstrate that word-initial /l/ is becoming darker in apparent time: younger speakers have darker /l/s. There is, however, no evidence that the allophonic status of /l/ is changing, with /l/ in all positions becoming darker. There is a monotonic relationship with social class: the higher the social class, the lighter the /l/, with some middle-class speakers showing potential of an allophonic distribution. We find an effect of ethnicity, with white speakers having darker /l/s in comparison to Black and Pakistani Mancunians. Overall, our findings are a novel contribution to the understanding of the sociophonetics of English laterals and provide new evidence of social patterning and the allophonic status of /l/ in this variety.
Penthemimeral Elision in Tragic Trimeters
Authors: Clark James T.
Published: November 2021

This paper provides a statistical survey of the incidence of elision at the penthemimeral caesura in the iambic trimeters of Greek tragedy. It updates and builds on the work of Descroix (1931) by considering the rates of elision of different types of words: lexicals, nonlexical polysyllables, and nonlexical monosyllables. While all tragedians elide less at the caesura than throughout the line, in Aeschylus the rate of this reduction is far greater for lexicals and polysyllabic nonlexicals than it is for monosyllabic nonlexicals. On this evidence, and the evidence of interlinear elision, it is tentatively suggested that lexicals and nonlexical polysyllables should together be considered as the more constrained elisions. When the rates of constrained elision are examined, the difference between Aeschylus and later Euripides is revealed to be twice that obtained when bulk figures are used. This difference is attributed to a combination of Euripides’ adoption of more fluent phrasing towards the end of his career and the tragedians’ different approaches to compositional constraints.

Der Nutzen von körperlicher Aktivität im Kindes- und Jugendalter mit und ohne Diabetes ist unbestritten. Trotzdem werden aktuelle Empfehlungen kaum erreicht. Einen möglichen Ansatz bietet die Förderung der Physical Literacy bzw. der bewegungsbezogenen Gesundheitskompetenz, die als ganzheitliche Grundlage für ein lebenslanges Bewegen verstanden wird. Dies sollte aber in verhältnispräventive Maßnahmen eingebettet werden, um auch die Lebenswelten von Kindern und Jugendlichen bewegungsfreundlicher zu gestalten.

Predicting conductivities of alkali borophosphate glasses based on site energy distributions derived from network former unit concentrations
Authors: Bosi Marco , Maass Philipp
Published: November 2021

For ion transport in network glasses, it is a great challenge to predict conductivities specifically based on structural properties. To this end it is necessary to gain an understanding of the energy landscape where the thermally activated hopping motion of the ions takes place. For alkali borophosphate glasses, a statistical mechanical approach was suggested to predict essential characteristics of the distribution of energies at the residence sites of the mobile alkali ions. The corresponding distribution of site energies was derived from the chemical units forming the glassy network. A hopping model based on the site energy landscape allowed to model the change of conductivity activation energies with the borate to phosphate mixing ratio. Here we refine and extend this general approach to cope with minimal local activation barriers and to calculate dc-conductivities without the need of performing extensive Monte-Carlo simulations. This calculation relies on the mapping of the many-body ion dynamics onto a network of local conductances derived from the elementary jump rates of the mobile ions. Application of the theoretical modelling to three series of alkali borophosphate glasses with the compositions 0.33Li2O–0.67[xB2O3–(1 − x)P2O5], 0.35Na2O–0.65[xB2O3–(1 − x)P2O5] and 0.4Na2O–0.6[xB2O3–(1 − x)P2O5] shows good agreement with experimental data.
First Record of the Saproxylic Beetle Cossonus parallelepipedus (Coleoptera, Curculionidae) in Bosnia and Herzegovina
Authors: Vesnić Adi , Mujezinović Osman , Pernek Milan , Dautbašić Mirza , Ivojević Sead , Kulijer Dejan
Published: November 2021

Balkan Peninsula is considered to be a hotspot of beetle biodiversity. Registering occurrence of saproxylic beetles is an important first step for expanding the general knowledge about saproxylic beetles as ecologically important insect species. Cossonus parallelepipedus is a European saproxylic species distributed from Iberian Peninsula in the west to Russia in the east, and from the Mediterranean in the south to Fennoscandia in the north. The first, and until now the only find of this species for the Balkan Peninsula is from Croatia. We report the first find of C. parallelepipedus in Bosnia and Herzegovina (BiH). In April 2020, larvae, pupae and imagoes were collected, in the central part of BiH, north of Sarajevo, on Zvijezda Mt. near Vareš from decaying moist wood in the lower part of a tree trunk of European silver fir, Abies alba. We expect that this species has a wider presence, especially in mountain areas in the central part of the country. Due to the similar environment conditions for other two European Cossonus species ( C. cylindrus and C. linearis) their presence is also possible.
Varieties of Digital Authoritarianism
Authors: Howells Laura , Henry Laura A.
Published: November 2021

Digital authoritarianism threatens the privacy and rights of Internet users worldwide, yet scholarship on this topic remains limited in analytical power and case selection. In this article, we introduce a comprehensive analytical framework to the field of Internet governance and apply it first, briefly, to the well-known case of China and then, in more depth, to the still-understudied Russian case. We identify the extent and relative centralization of Internet governance as well as proactive versus reactive approaches to governance as notable differences between the cases, highlighting variation among digital authoritarians’ governance strategies. We conclude that Russia’s Internet governance model is less comprehensive and consistent than China’s, but its components may be more easily exported to other political systems. We then consider whether recent changes to Russia’s Internet governance suggest that it could converge with the Chinese model over time.
Killing Politics Softly
Authors: Shields Paul
Published: November 2021

Early propaganda studies in authoritarian countries argue that state media works to legitimize the regime through indoctrination and persuasion. However, recent scholarship shows that citizens in authoritarian countries—in states like China, Syria, Russia, and Kazakhstan—can be unconvinced by state propaganda. How, then, does the way in which citizens experience unconvincing propaganda shape their political beliefs? How might unpersuasive propaganda contribute to authoritarian stability? Given the lack of alternative theories of propaganda, this article proposes a new hypothesis based on a reception study that interviewed 24 Russian citizens from Krasnoiarsk Krai after they watched items from Russian state television. The article theorizes that unconvincing state propaganda in Russia can reinforce a preexisting cynical attitude toward politics—an attitude that makes the collective action necessary for bottom-up reform hard to contemplate, let alone organize in an authoritarian context.
Migration and Soft Power
Authors: Ruget Vanessa , Usmanalieva Burul
Published: November 2021

This article explores how Kyrgyz labor migrants in Russia view their host country’s government and its influence in Kyrgyzstan, including through the Eurasian Economic Union. Results suggest that migrants have nuanced, pragmatic pro-Russian views. They understand Kyrgyzstan’s dependency on Russia and admire the efficiency of Russia’s government. Yet, they also disapprove of its high levels of corruption and of its disregard for individual rights. Our work contributes to the literature on the diffusion of norms through migration; it also sheds light on Russia’s soft power in Central Asia at a time when rivalry with China is growing in the region.

Exploring the Usability of Virtual Robotics Programming Curriculum for Robotics Programming Teaching
Authors: Kılıç Servet , Gökoğlu Seyfullah
Published: November 2021

This study aims to explore the usability of the virtual robotics programming curriculum (VRP-C) for robotics programming teaching. Pre-service computer science (CS) teachers were trained for robotics programming teaching by using VRP-C in a scientific education activity. After training, views of the participants were revealed by using a scale and an evaluation form consisting of open-ended questions. Results show that VRP-C is compatible with the curriculum for robotics programming teaching in schools, and pre-service CS teachers tend to use VRP-C in their courses. They think that VRP-C will be beneficial for robotics programming teaching in terms of content, functionality, and cost. Compatibility, visual design, feedback, time management, fiction, gamification, and cost are the characteristics that increase the usability of VRP-C. VRP-C can be used as an online tool for robotics programming training due to the necessity of transition to distance education because of the COVID-19 pandemic.

Subject and Purpose. The maintenance of physical and chemical properties and biological stability of lubricoolants during downtimes, which are bound to happen sometimes and last long, is a hot problem in metalworking industry. The procedure of bubbling for the lubricoolant mixing, saturation with oxygen and inactivation of anaerobic microflora calls for chemical and biological techniques to monitor the lubricoolant condition during the bubbling and after it. Yet the standard methods lack responsiveness and accuracy of the analysis, implying the further refinement of the output values. In the present work, microwave super-high frequency (SHF) dielectrometry is employed for the examination of the dielectric constant and dynamic surface tension of synthetic, semi-synthetic and organic emulsions during the bubbling. Methods and Methodology. The dielectric constant and dynamic surface tension of 5.7 % water-soluble emulsions are measured at frequency f = 37.7 GHz. A frequency sweep in the acoustic frequency range f = 20…25000 Hz is used, for which purpose the end of the 8-mm waveguide is supplied with a piezo сell. Results. It has been revealed that the dielectric constant and dynamic surface tension of lubricoolants depend on the physicochemical characteristics that the lubricoolants acquire during a month-long downtime and after 10-, 20-, and 30-minute bubblings. The dielectric constant and dynamic surface tension demonstrate that the bubbling improves lubricating properties of all the emulsions examined. For this, a 10-minute bubbling is enough for semi-synthetic lubricoolants, and a 20-minute bubbling is needed for synthetic and organic lubricoolants. Conclusion. The microwave dielectrometry method with a frequency sweep in the acoustic frequency range can be used in metalworking industry as an aid to lubricoolant quality control during the downtime or storage.
Model of Angular Momentum Transport at the Protoplane-tary Disk Evolution and Disk Surface Density
Authors: Belghitar E.B. , Meftah M.T. , Malki Z.
Published: November 2021

We consider how the tidal effect of a protoplanetary disk interaction can be incorporated into calculations of its viscous evolution. The evolution of the disk occurs under the action of both internal viscous torques and external torques resulting from the presence of one or more embedded planets. The planets migrate under the effect of their tidal interaction with the disk (in the type-II migration regime). Torques on a planet are caused by its gravitational interaction with the density waves which occupy the Lindblad resonances in the disk. Our model simplifies the functional form of the rate of injection of the angular momentum Λ(r) to construct and solve the evolution equation for a disk and an embedded protoplanet. The functional Λ(r) depends on the tidal dissipation distribution in the disk which is concentrated in a vicinity of the protoplanet’s orbit. We have found an analytic solution for the disk surface density.

Authors: Bonova I.
Published: November 2021

PURPOSE: The aim of the study is to determine the sensitive windows related to motor skills development as well as the rate of trainability of the adolescent hockey players from the Bulgarian Youth National Field Hockey Team. METHODS: This study included 20 adolescent field hockey competitors at the national level – boys at an average age of 13.5 years. The experiment was conducted twice with the same participants at an interval of 16 weeks. They were assigned into two groups: responsive and non-responsive. Those who achieved an improvement in two or more motor tests were included in the “responsive” group. Those who did not improve their performance in the motor tests were included in the group of “non-responsive” players. RESULTS: The findings from the study show that considering the age (13.5), aerobic and anaerobic conditioning is trainable (VO2max and 30 m speed test). DISCUSION: The responsive group was determined to be of high and slow trainability, while the non-responsive one – of low and slow trainability, hence the prospects of the latter for staying in the national team are not favorable. CONCLUSION: It can be recommended that the head coach select only players of medium level trainability for the 2020 Summer Championship.

Authors: Petkov P.
Published: November 2021

The purpose of the present study is to establish the factor relationships between morpho-functional parameters and physical qualities, muscle strength and endurance due to the application of a specialized fitness model. To achieve this goal we the following tasks are set: research of literature resources; development and testing of a specialized fitness model; development of a test battery; processing and analyzing the data from the conducted testing. Research methods - pedagogical experiment, testing, factor analysis, graphical analysis. The contingent of the study are 34 students from the Trakia University. The students are on average 20.04 years old. The results and their analysis show that in the applied fitness model there is a decrease in the number of the main factors in the factor structure of the morpho-functional indicators and the observed motor functions; the increase in the influence of the first main factor in the second study explains the higher percentage of the cumulative variance. This leads to structural changes in the content of the main factors; changes the influence of factors, which after the experiment increases the influence of endurance due to the composition of body weight; the force factors retain approximately the same weight in the second study.

Published: November 2021

Abroma augusta L. known as Devil’s cotton belongs to Malvaceae. The exploratory study aimed to study the morphological and anatomical characteristics of the aerial parts of A. augusta L. from Semarang. The transverse section of the aerial parts was made by a simple method (fresh preparation) and then observed under a binocular microscope with an optilab. All characteristics were observed and then compared with the references. The collected data were analyzed descriptively and quantitatively. In summary, the results showed that A. augusta L. was an evergreen shrub (small tree) with orthotropic and plagiotropic branches and polymorphous leaves. The inflorenscence was found in the terminal and axillar plagiotropic branching with bisex, actinomorphic, and pentamerous flowers. The fruit was unique (obconical capsule with a rounded base and truncate-tip with 5 angled wings) including cotton fibers and numerous black seeds. The petiole was composed of epidermis, collenchyma, cortical parenchyma, sclerenchyma, vascular bundle, mucilaginous ducts, and pith. The dorsiventral leaf was composed of upper and lower epidermis, palisade, and spongy parenchyma. The stomata type was ranunculaceous (anomocytic) while the guard cell was kidney-shaped. The stomata density on the abaxial leaf was higher than that of the adaxial leaf. The stellate and unicellular non-glandular trichomes, and capitate glandular trichomes were found abundantly on the petiole and leaf blade. These morphological and anatomical studies are important to support the identification as a part of the conservation effort of the plant. Further studies are recommended to investigate the root morphology and anatomy and also biochemical characteristics of each part of the plant in order to obtain  complete plant identification.

Published: November 2021

In the Miocene era about 20 million years ago, the South Coast of West Java was a sea and habitat for marine organisms including giant sharks Megalodon measuring about 18 meters long. This study aimed to model the habitat preference of the prehistoric gigantic shark Otodus megalodon population based on the fossil record. From fossil teeth, it revealed that the rock layer where the teeth found was Bentang formation from Miocene era. Many fossils of Megalodon had been unearthed from Bentang formation which is part of the South Coast of West Java. The habitat model was developed using the Sea Level Rise Inundation Tool of ArcGIS to estimate the sea depth and Megalodon’s habitat during the Miocene. The length of the teeth of O. megalodon found was ranged from 13 to 19 cm, indicating the presence of juvenile and adult O. megalodon. Based on the model, in the Miocene era, half of West Java was a sea with a depth ranging from 0 to 200 meters. At that time, it was estimated that juvenile O. megalodon occupied waters with a depth of 0-40 meters with an area of 1365 km2. Meanwhile, adult O. megalodon prefers a depth of 80-160 m and the frequency of habitat use increases at a depth of 200 m. The declining population of O. megalodon is associated with climate change and declining prey populations.

Sida rhombifolia is one of wild flowering plants that grows easily in many habitats with moderate humidity, with some usefulness in traditional medicine. Genetic characterization of Sida rhombifolia accessions originated from 12 ethnicities of Indonesia was analyzed based on Sequence-Related Amplified Polymorphism (SRAP) Markers. The genomic DNA were extracted from leaf samples and then were characterized by using the SRAP marker system according to Li and Quiros (2001). Nine pairs of SRAP primer resulted high polymorphic bands and were used in the genetic profiling. The data analysis was performed using GenAlEx to calculate genetic distance, Principal coordinate analysis, and Analysis of Molecular Variance (AMOVA), also using POPGENE to assess genetic diversity (Hs and Ht) and Nm to predict gene flow among populations. The coordinate analysis showed that the accessions originated from ethnicities along Wallacean line tend to differ genetically from most other locations. However, the results of analysis of molecular variance suggested that there were only slight differences (0.1%) found between ethnicities, while most genetic variances (99.9%) were found mostly among accessions within populations. The results suggested that there was an extensive genetic flow and plant spreading among Sida rhombifolia plant populations, resulting more homogenous genetic characters among most populations, while high diversity within population. The calculation of the number of migration (Nm = 1.7341) confirmed that the high rate of gene flow had occurred between populations.
La protección del menor de edad ante los abusos sexuales: su salvaguarda obtiene carta de naturaleza
Authors: Núñez Gerardo
Published: November 2021

Hasta la actual reforma del Libro VI del Código, la legislación sobre abusos sexuales a menores y personas vulnerables se encontraba en normas extracodiciales a las que se debían remitirse tanto a su concepto como a aspectos procedimentales en su castigo. Esto era debido al cambio de mentalidad en la sociedad civil y en la Iglesia al tratar estos delitos: en la actualidad se centra en el cuidado de las víctimas. Con la reforma, el aspecto conceptual se ha incluido expresamente. Se explica el contenido de los nuevos delitos, así como su influencia en otras posibles modificaciones en el Código.
Examining the Relationship between Depression, Anxiety and Stress in Kidney Cancer Patients
Authors: Demirtaş Türev , Temircan Zekeriya
Published: November 2021

Cancer of the kidney is one of the 10 most common cancers found globally. Overall, it is the fourth most common cancer in men and the eighth most common cancer in women. Many kidney cancer patients experience psychologic problems and reactions. The present study examined relationship between anxiety, depression, and perceived stress symptoms in kidney cancer patients. Cross-sectional data were obtained from the patients diagnosed with kidney cancer. All participants completed sociodemographic form, Hospital Anxiety and Depression form, and Per-ceived Stress Scale. Statistical analysis was exercised using the Student’s t-test, Chi-squared test (χ2), Fischer’s exact test, ANOVA, Mann–Whitney U test, and Kruskal–Wallis one-way variance analysis. A total of 250 patients participated in the study. The mean age was 57.4 years (SD 6.4, range = 25–76 years). The majority of patients were males (73%) and married (218). Anxiety symptoms were determined in 91.2% patients, depression symptoms in 87.2% patients, and perceived stress symptoms in 93.6% patients. The mean scores of Hospital Depression and Anxiety Scale (HADS)-Anxiety, HADS-Depression, and HADS-Perceived Stress were significantly different between age (P < 0.05), gender (P < 0.05), and income groups (P < 0.001). Kidney cancer patients showed poorer psychologic health. The overall levels of anxiety, depression, and perceived stress symptoms were higher among the studied kidney cancer patients. Findings of the current study could improve both psychologic well-being of patients and health-related quality of life.

Continuality of Language Levels Hierarchy
Authors:   Samara State University of Social Sciences and Education, Savitsky Vladimir
Published: November 2021

The author points out that the structure of language levels system is still a crucial linguistic problem, that research in this field is far from being completed and that there is a need for further improvement of the current models of language levels hierarchy. The author sets out his reflections that sprang up from striving to eliminate some contradictions in the existing models of the language levels system. Applying the method of comparative analysis, elements of the model theory and linguistic systemology, using the Russian language material supplemented by some sporadic examples from other languages, the researcher puts forward a number of amendments to the existing models of the language levels hierarchy – amendments intended for riddance of the above-mentioned contradictions. The author argues in favor of merging the morphological and lexical levels, as well as the level of syntax and that of utterances, and offers insertion of the word combinations level at which language units and speech units co-exist, forming two intersecting sub-levels. The expediency of combining the system of language levels and that of speech levels into a common speech-language space has been proved. Using the empirical material, the author demonstrates the level boundaries blurring and existence of inter-level gaps, which contain hybrid units that have typological features of both the upper level and the lower level. The following conclusion is drawn: the speech-language hierarchy must be schematically presented not so much a column of hard and fast lines as a linguistic continuum with smooth transitions between the levels.
Morphonological Phenomena in the Kalmyk Language of the 18th Century (Exemplified by the Documents of the National Archive of the Republic of Kalmykia)
Authors:   Kalmyk State University named after B.B. Gorodovikov, Suseeva Danara
Published: November 2021

The results of the analysis of morphonological phenomena in the words of the Kalmyk language of the 18 th century are presented in the article. The research material is comprised of the official business documents of the Kalmyk khans of the 18 th century and their contemporaries, written in the old Kalmyk language, called Todo bichig "clear letter", which were deposited in the National Archive of the Republic of Kalmykia (Fund 36, Inventory1). In Kalmyk linguistics, for the first time, information was obtained about the compatibility of morphemes of the Kalmyk language of the 18 th century and about morphonological phenomena caused by the processes of word- and form building. It was found out that at the junction of morphemes such morphonological phenomena as truncation, overlap, augmentation, alternation, interfixation, vowels lengthening often occurred, and within morphemes – the alternation of short and long vowels. It is revealed that the paradigms of root and subordinate morphemes of the 18 th -century Kalmyk language differ from similar paradigms of the modern language. The results obtained are important not only for understanding the historical grammar of the Kalmyk language, but also for the theoretical grammar of the modern Kalmyk language. The perspective of this study is that its results are the starting point for a new direction – the comparative study of morphemics and morphonological phenomena of related Mongolian languages belonging to the agglutinative type of languages. It becomes possible to compare and contrast not just their single identical root and affixal morphemes (the traditional approach), but also their morphemic paradigms, consisting of allomorphs and variants in both diachronic and synchronous aspects.

Published: November 2021

This paper examines how the recognition and spread of the International Financial Reporting Standards (IFRS) have affected accounting practices and accounting education in Russia. We use evidence from Russia as a case study to provide a historical perspective on the changes in its accounting system and analyze the translation and communication difficulties in accounting practices and education. By conducting Russian accounting textbooks’ content analysis, we highlight IFRS translation issues in order to investigate the positional statement of the problems regarding the challenges with IFRS education. We also discover the current difficulties in teaching IFRS-based accounting to non-English speakers. Our findings outline the interrelation between the educational approach and practical applications of the existing knowledge on financial reporting. Finally, this research addresses the nature of the challenges that emerge due to the linguistic translations of the IFRS. We consider this paper will be of particular interest for non-native English-language speakers, including academics, practitioners, and standard setters.
Does Self-Esteem Really Matter? Determining the Role of Self-Esteem in Cynical-Silent Employees
Authors: USLU Osman
Published: November 2021

The aim of this paper is twofold. First, it was aimed to determine whether there are positive associations between cynicism and acquiescent and defensive silence, and negative association between cynicism and prosocial silence. Second, drawing on behavioral plasticity theory, potential moderating effects of self-esteem in the predicted associations were explored. A quantitative research was designed, and 522 employees included in the research. Even though self-esteem had a moderating effect on cynical-prosocial silent employees, and unlike the behavioral plasticity theory it did not have any critical buffer role. Within the context of current study, therefore, it has been concluded that self-esteem is not as significant as it has been exaggerated in the literature.
