Published: May 2023

At the present stage of economic and logistics development, information technologies, artificial intelligence, as well as other achievements of scientific and technological progress are singled out as one of the promising areas, the introduction of which exposes the conditions for creating value of services to forced transformation. Many factors have become the catalyst for such rapid changes. However, among the key ones, it is worth noting the pandemic, thanks to which contradictions between the development of elements of economic systems, both at the state level and in individual production and marketing links were revealed. The pandemic has shown that it is technology, digitalization and innovation that determine the most significant factors for increasing the efficiency of production and distribution systems, including transport and logistics. In this regard, the subject of the study is the process of creating the value of transport services in the new conditions of maritime business. The purpose of the study is to develop a conceptual approach to creating the value of transport services, which will increase the efficiency of production activities of enterprises by maximizing the satisfaction of new business conditions. The methods of studying and generalizing domestic and foreign experience, the analytical method were used in the work. A review of scientific sources was carried out, analytical materials were investigated, and an oral survey of representatives of the maritime business was conducted. It is determined that in the new conditions the value of the transport service is formed due to the coordinated interaction of all participants in the cargo delivery chain. A model of value creation of transport services based on a globally synergetic approach and considering information innovations implemented today in maritime transport is presented.

The article is devoted to the discussion of topical theoretical aspects of the problem of adaptation of fifth graders, the features of their development and the process of adaptation, diagnostics, and analysis of methods aimed at studying anxiety, self-esteem, state in the lesson. By creating adaptive situations, the school is the bearer of the richest social experience, including the adaptation of the student to the content and form of education. The analysis showed that the main task of the educational institution is to create conditions for the successful adaptation of students, which is the key to high-quality education of the individuals, their further improvement and self-development. For each stage of the research (theoretical, empirical, interpretative), its own group of methods is defined: theoretical: collection of information, generalization, systematization, analysis of scientific literature; empirical: ascertaining research, testing, questioning; psycho-diagnostic: testing according to the method of diagnosing the level of school anxiety by B.N. Phillips, questioning according to the method of studying the emotional state of students “Subject-feelings” by T.E. Kovina, A.K. Kolichenko and I.N. Agafonova, testing by the method of diagnostics of general self-esteem G.N. Kazantseva. A sample of 120 fifth grade students of the Municipal Autonomous Educational Institution Secondary School No. 138, Chelyabinsk, was formed. It was revealed that increased levels of anxiety are observed to a small extent, the majority of fifth-graders do not experience mental discomfort and anxiety, they are balanced and emotionally stable. The average value of the index of emotional positivity of fifth graders during class attendance is observed in 74 %, which indicates their satisfaction in most subjects, a fairly comfortable internal climate in the classroom. In general, the process of adaptation of fifth graders in the middle level can be considered satisfactory, but there are students who have low emotional positivity to learning – 26 % and low self-esteem – 19 %. The recommendations compiled based on the results of the study can contribute to the effective adaptation of fifth graders to study in a general education organization and can be useful to both parents and all subjects of educational relations.
Toponymy of Celtic Scotland
Authors: Kalinina S.A.
Published: May 2023

It has long been known that there is a certain link between a geographic locality and its name. The paper attempts to link the history, geography, and culture of Scotland with the names of its cities, homesteads, rivers, streams, mountains, hills, and other localities that are either man-made creations or natural phenomena. Despite covering mere 80,000 km2, Scotland is a unique region. Scotland is almost completely washed by sea, although most of its territory lies on the uplands. Mountains, hills, valleys, rich in diverse vegetation, conjure up an attractive look of Scotland. This very landscape forged the features of Scottish place names, one of the oldest place names on the world map. The paper will touch upon the earliest period when the names of Scottish geographic localities appeared, the period when this amazing country, currently part of the United Kingdom of Great Britain and Ireland, was conquered by the Celtic tribes who penetrated this land in different centuries. First, the author dwells on word-building formants enabling to classify the place names of Scotland as part of the “Celtic” period of language evolution. Some elements including aber, ach, auchter/ochter, bail/baile, barr, blair, coil, dal, gart, inver, mach, pit, tulach , dating back to Celtic language culture, are part of most units of the place-name vocabulary of Scotland and primarily denote natural features of the landscape of the target region.
Magical thinking as a socio-psychological phenomenon of spiritual life in the early 21st century
Authors: Serdyuk E.G.
Published: May 2023

The paper considers the phenomenon of magical thinking as a cognitive-emotional distortion of a person’s perception of objective reality from the standpoint of the doctrine of esotericism. The author analyzes esotericism as a sociocultural and psychological phenomenon. The question of understanding life, finding subjective meaning, understanding and determination of a person’s place in reality and beyond the space that the understanding is able to catch is the main question of philosophy, where esotericism is a specific direction in the process of world perception. In modern society such global events as the pandemic, military conflicts, natural and technogenic disasters influenced the position of a person in terms of understanding of his role in current circumstances. The paper analyzes the transformation of a common vision of a person’s position and role in an objective space, the formation and spread of magical thinking as a result of experiencing the helplessness of a person in large-scale events, an insufficient level of readiness for difficulties and a reduced level of personal responsibility for their contribution to current events. The author considers the esotericism doctrines and their influence on the formation of the worldview of a modern person.

Authors: Idigova Lalita , Plis Svetlana , Chaplaev Huseyn
Published: May 2023

The paper considers modern technologies of personnel management necessary for the digital economy. Nowadays, in the process of transforming HR approaches due to the pandemic and economic situations, most companies in general and HR management in particular are faced with an acute question: what to do with the HR strategy. The study is aimed at identifying relevant areas of digitalization of the HR management process in a business organization. The paper authors identify basic reasons hindering the transition of personnel management to digital technologies, as well as opportunities for their further solution. The authors believe that the digitalization process is irreversible in modern conditions and enterprises should pay attention to this significant aspect. Most business leaders are not ready for the introduction of digital technologies and believe that they may negatively affect the employment level. On the contrary, another part of managers is introducing digital technologies, trying to improve the skills of employees in order to meet labor market standards. The authors conclude that a large role in the efficient formation of personnel management is the presence of personnel, formed from specialists with a psychological education and with the ability to solve mathematical tasks. The authors believe that the demand for such specialists will increase every year. Besides, high-quality personnel management is becoming a strategic center for the enterprise development, which the corporate brand formation depends on. Most enterprises prefer to do business online; it becomes a trigger for the formation of new approaches in the field of the company personnel management, which has always been a complicated and multifaceted phenomenon.

The study comprised 43 students of the 10th grade of a comprehensive school with socio-economic bias and lyceum with physical and mathematical bias. Lung capacity was measured using a dryair spirometer. According to the results of spirometry, the functional state of the respiratory system in the majority (76.67 %) of the tested schoolchildren and lyceum students turned out to be below average, which indicates a lag in their physical development. The endurance ratio was calculated in order to characterize the functionality of the cardiovascular system. For the majority of students (97.68 %) it corresponded to the average level, and for the minimum number of students (2.32 %) it was low. The functional state of the body was also assessed by determining the stress level indicator. In 81.82 % of schoolchildren, the stress level at rest had a value corresponding to its increase, and only in 18.18 % of schoolchildren, the stress level indicator was within the normal level. Thus, most tenth graders experienced high levels of stress. In addition, the psycho-emotional state of students was studied by other methods using standard tests: determining the level of personal and reactive (situational) anxiety, assessment of personal well-being, activity and mood. The results of self-assessment of lyceum students and schoolchildren corresponded to good and favorable conditions. Among tenth graders, 8.7 % of lyceum students were characterized by an unfavorable condition. 30.4 % of lyceum students and 55.0 % of schoolchildren with high personal anxiety were identified.
The peoples of the North Caucasus in the works of Russian writers of the first half of the 19th century
Authors: Gapurov Shakhrudin Aidievich , Bugaev Abdul Makhmudovich , Magamadov Supyan Sultanovich
Published: May 2023

The paper deals with the problem of attitude of different strata of Russian society towards the North Caucasus and highlanders in the first half of the 19th century. At the beginning of the 19th century, Russia began to expand its influence in the North Caucasus region, yet Russian society had a vague idea of its peoples. The author focuses on the fact that a prominent Russian poet A.S. Pushkin showed the Caucasus as a ‘wonderful land’ inhabited not by ‘predators’, but by proud, freedom-loving, courageous highlanders. Pushkin’s poetry exerted an enormous influence on his contemporaries. M.Yu. Lermontov, A. Polezhaev, and K. Belevich, active participants in the Caucasian War, did even more in glorification of the liberation struggle of highlanders and condemnation of the policy of tsarism in the North Caucasus. A.S. Griboyedov, one of the brightest representatives of advanced Russia, made a great contribution to Russian-Caucasian social and cultural relationships when he served in the Caucasus. A. Bestuzhev-Marlinsky, the Decembrist writer, also contributed to the formation of a positive image of a highlander as a knight gifted with noble qualities. His first works appeared in 1832 and had great success among the progressively-minded Russian people.

Authors: Borodina Lyudmila , Klimenko Ekaterina , Rychenkova Anna
Published: May 2023

The article discusses the stages of the formation of professional competencies in the process of training future engineers of the Navy. An analysis of the concept of competence in the interpretation of modern scientists is carried out. The features of the formation of professional competence are analyzed, considering the specifics of a general technical academic discipline, and the integral role of skills and abilities as objects traditional for pedagogy is shown. It is shown that the competencies that a university graduate must master can be divided into two classes: professional (subject-specialized) and general cultural (universal), not directly related to the solution of professional problems, but related to the success of the professional activity. As a result of the analysis of the task of designing the content of subject competencies, the fundamental functional structure of the process of forming the professional competence of a general technical academic discipline is presented. The problem of the relationship between sensory (empirical) and rational (theoretical) knowledge is revealed in the aspect of applying theoretical knowledge in the practical activities of a transport specialist.

Published: May 2023

The work aims to consider issues related to the peculiarity of interrogating suspects with the participation of an interpreter in the investigation of crimes during the preliminary investigation. The specificity of this situation is determined by the fact that the criminal procedural legislation of the Russian Federation for a person who does not speak language of legal proceedings or does not have a sufficient level of this language provides for the right to use the services of an interpreter free of charge. At the same time, the tactical recommendations for interrogation that exist in forensic science are developed for a situation when the subject of law enforcement and the interrogated person communicate in the same language. In addition, a significant difficulty in interrogation is the very terminology related to various spheres of human activity, which is as important for an interpreter as the ability to translate. The method of achieving the stated goal is to compare tactics typical for the situation of monolingualism and multilingualism of participants in criminal proceedings. The article deals with the organizational, tactical and psychological features of interrogation of a suspect: characteristics of pre-interrogation situations, interrogation tactics, features of presenting evidence in order to obtain truthful testimony. The article shows significant differences in interrogation of a suspect with the participation of an interpreter in the investigation of crimes.

Authors: Fooladi Masoomeh , Rezaei Sahar , Aghahosseini Farahnaz , Salehi Yalda , Kasraie Nima , Sheikhzadeh Peyman
Published: May 2023

Objective This study aims to assess the impact of various regions of interest (ROIs) and volumes of interest (VOIs) delineations on the reproducibility of liver signal-to-noise-ratio (SNRliver) measurements, as well as to find the most reproducible way to estimate it in gallium-68 positron emission tomography (68Ga-PET) imaging. We also investigated the SNRliver-weight relationship for these ROIs and VOIs delineations.

Methods A cohort of 40 patients (40 males; mean weight: 76.5 kg [58–115 kg]) with prostate cancer were included. 68Ga-PET/CT imaging (mean injected activity: 91.4 MBq [51.2 MBq to 134.1 MBq] was performed on a 5-ring bismuth germanium oxide-based Discovery IQ PET/CT using ordered subset expectation maximization image reconstruction algorithm. Afterward, circular ROIs and spherical VOIs with two different diameters of 30 and 40 mm were drawn on the right lobe of the livers. The performance of the various defined regions was evaluated by the average standardized uptake value (SUVmean), standard deviation (SD) of the SUV (SUVSD), SNRliver, and SD of the SNRliver metrics.

Results There were no significant differences in SUVmean among the various ROIs and VOIs (p > 0.05). On the other hand, the lower SUVSD was obtained by spherical VOI with diameter of 30 mm. The largest SNRliver was obtained by ROI (30 mm). The SD of SNRliver with ROI (30 mm) was also the largest, while the lowest SD of SNRliver was observed for VOI (40 mm). There is a higher correlation coefficient between the patient-dependent parameter of weight and the image quality parameter of SNRliver for both VOI (30 mm) and VOI (40 mm) compared to the ROIs.

Conclusion Our results indicate that SNRliver measurements are affected by the size and shape of the respective ROIs and VOIs. The spherical VOI with a 40 mm diameter leads to more stable and reproducible SNR measurement in the liver.
Open Volar STT Ligament Reconstruction to Augment the Mathoulin's Arthroscopic Dorsal Capsuloligamentous Reconstruction: Technique Description and Case Reports
Authors: Smith Nicholas Charles , Yates Sally E. , Mettyas Tamer
Published: May 2023

Background The results of Mathoulin's arthroscopic dorsal capsuloligamentous reconstruction (ADCLR) are excellent in many patients with scapholunate instability, though less consistently good in higher grade instabilities. The purpose of this article is to describe a novel technique of volar scaphotrapeziotrapezoid (STT) reconstruction which may be used to augment rotational control of the scaphoid, in conjunction with the ADCLR, for use in European Wrist Arthroscopy Society (EWAS) grade IV/V instabilities.

Description of Technique Following completion of ADCLR, the STT joint is approached through the flexor carpi radialis sheath. The palmaris longus tendon is harvested. Fluoroscopy is used to site guide wires for tunnel placement in the distal scaphoid and the proximal trapezium; 3.5-mm tunnels are overdrilled in both bones, to a depth of 8 mm. The palmaris graft is then anchored in the scaphoid tunnel with a mini-DX SwiveLock anchor. The graft is tensioned, then anchored in the trapezium tunnel with another anchor.

Patients and Methods We retrospectively selected two young men heavy manual workers who had this procedure more than 12 months previously for scapholunate instability, with static radiographic abnormalities and a drive through sign (EWAS grade V). The patients were reviewed after 12 months, for assessment of visual analog scale, quick disabilities of the arm, shoulder, and hand, and patient-rated wrist/hand evaluation scores, range of motion, and grip strength.

Results Both patients had marked improvements of wrist comfort and function at 1 year, and were able to return to their normal duties at work and complete all activities of daily living with minimal symptoms.

Conclusion This volar STT reconstruction may expand the success of the Mathoulin's ADCLR into higher grade instabilities.

Suppressed polaronic conductivity induced sensor response enhancement in Mo doped V2O5 nanowires
Authors: Anson Anakha , Mondal Dipanjana , Biswas Varsha , Urs MB Kusuma , Kamble Vinayak
Published: May 2023

In this paper, we show the direct correlation between the suppression of the polaronic oxygen vacancy defect (Vo) density and gas sensor response of 1 at. % Mo-doped V2O5 nanowires (MVONWs). Doping 1 at. % Mo5+ leads to substitution at the V5+ site in V2O5 nanowires (VONWs) and, therefore, reduction in Vo defects. This, in turn, affects the charge carrier hopping sites and, subsequently, enhances the sensor response at lower temperatures (<320 °C). The Mo5+ dopants lead to the lowering of Fermi energy (EF) toward valence band maxima due to the reduced Vo donor density. The polaron suppression is confirmed with the activation energy of polaron hopping, increasing from 195 to 385 meV in VONWs and MVONWs. As a result, the response to ethanol gas enhanced as the depletion width is widened for the given cross section of the nanowires. This may lead to a large depletion controlled cross-sectional area and, therefore, better sensitivity. At about 350 °C, VONWs show a change in the slope of resistance vs temperature (MIT), which is not observed in the case of MVONWs. This is attributed to the presence of the enhanced non-stoichiometry of V ion resulting in metallic behavior and accompanied by a sudden rise in the sensor response at this temperature. Moreover, the absence of MIT may be attributed to the lack of such a sudden rise in the response in MVONWs.

Control noise is a limiting factor in the low-frequency performance of the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO). In this paper, we model the effects of using new sensors called Homodyne Quadrature Interferometers (HoQIs) to control the suspension resonances. We show that if we were to use HoQIs, instead of the standard shadow sensors, we could suppress resonance peaks up to tenfold more while simultaneously reducing the noise injected by the damping system. Through a cascade of effects, this will reduce the resonant cross-coupling of the suspensions, allow for improved stability for feed-forward control, and result in improved sensitivity of the detectors in the 10–20 Hz band. This analysis shows that improved local sensors, such as HoQIs, should be used in current and future detectors to improve low-frequency performance.

It is widely recognized that hybrid (organic/inorganic) light emitting diodes (LEDs) are of concern because they use an organic material instead of rare earth phosphors, but extending their lifetime remains challenging. To construct organic luminescent material with high photoluminescence quantum yield (PLQY), a compound named 1-(4-(tert-butyl)phenyl)-2-(4′-(1-phenyl-1H-benzo[d]imidazol-2-yl)-[1,1′-biphenyl]-4-yl)-1H-phenanthro[9,10-d]imidazole (TPBI-BPI) was synthesized by connect two imidazoles units. The PLQY of TPBI-BPI is 0.97 in acetonitrile. The white light emission (WLE) of TPBI-BPI in ethyl acetate solution containing acetic acid was observed, and a solvent-type organic/inorganic hybrid white LED device based on TPBI-BPI was prepared. The luminance efficiency, external quantum efficiency, correlated color temperature, K, and Ra (color rendering index) of the solvent-type WLED are 21.71 lm/W, 12.76%, 6329, and 83.2 at 39.90 mA, respectively. The Commission Internationale de l´Eclairage coordinate of the solvent-type WLED is (0.3135, 0.3507). In addition, the lifetime (T70) of the device can reach 130 h. This is due to the excited state intermolecular proton transfer between TPBI-BPI and acetic acid in ethyl acetate solution after UV illumination. This enables TPBI-BPI to obtain WLE and makes the WLED spectrally stable due to this process's dissipation of UV energy. This work provides a strategy to extend the lifetime of a hybrid LED.
Study of atomic spectroscopy and electron collision process in non-ideal classical plasmas
Authors: Chen Zhan-Bin
Published: May 2023

This manuscript presents an approach to the calculation of atomic properties and the electron collision excitation process in a non-ideal classical plasma, based on the relativistic distorted wave methodology. The method incorporating the pseudopotential obtained from a sequential solution of the Bogolyubov chain equations, that yields modification term to the calculation of the central field potential, is employed to characterize the interactions among the charged particles in plasmas. The bound/continuous state wave functions and the electron collision excitation matrix elements are determined using the aforementioned pseudopotential within a relativistic Dirac–Coulomb atomic structure framework. Systematic investigations on the effects of non-ideality of plasma on the electronic structures, radiative properties, and excitation cross sections within a selected temperature and density range are carried out in the specific cases of H atom and Ca18+ ion as they make it possible to reproduce the reference data well and thus to conclude with the reliability of the (present) method developed. Apart from its fundamental importance, this study is essential for several applications, especially for the analysis of atomic processes in non-ideal plasmas, and offers a new perspective for the calculation of atomic properties under different conditions in various astrophysical and laboratory plasmas.
Two-pump optical manipulation of resonant spin amplification
Authors: Kesto Estefanio , Dominguez Michael J. , Sih Vanessa
Published: May 2023

An experimental and computational optical pump-probe model is constructed, which utilizes two ultrafast pump pulses within the repetition period of a mode-locked laser to generate electron spin polarization. This report focuses on the effects of resonant spin amplification induced by an infinite train of the two-pump pulses. The first pump pulse is used to generate ordinary resonant spin amplification spectra, while the second pump pulse is used to manipulate the generated spectra. This model gives control of the accumulation of spin polarized electrons along a magnetic field by selecting the temporal separation of the two-pump pulses. The computational model accurately predicts and agrees with the experimental results, which shows manipulation of resonant spin peaks that are no longer entirely dependent on the external magnetic field. This two-pump model and the associated manipulations of resonant spin peaks can be used as a platform to construct and conceptualize resonant spin amplification-based optospintronic devices and applications.
Proofreading does not result in more reliable ligand discrimination in receptor signaling due to its inherent stochasticity
Authors: Kirby Duncan , Zilman Anton
Published: May 2023

Kinetic proofreading (KPR) has been used as a paradigmatic explanation for the high specificity of ligand discrimination by cellular receptors. KPR enhances the difference in the mean receptor occupancy between different ligands compared to a nonproofread receptor, thus potentially enabling better discrimination. On the other hand, proofreading also attenuates the signal and introduces additional stochastic receptor transitions relative to a nonproofreading receptor. This increases the relative magnitude of noise in the downstream signal, which can interfere with reliable ligand discrimination. To understand the effect of noise on ligand discrimination beyond the comparison of the mean signals, we formulate the task of ligand discrimination as a problem of statistical estimation of the receptor affinity of ligands based on the molecular signaling output. Our analysis reveals that proofreading typically worsens ligand resolution compared to a nonproofread receptor. Furthermore, the resolution decreases further with more proofreading steps under most commonly biologically considered conditions. This contrasts with the usual notion that KPR universally improves ligand discrimination with additional proofreading steps. Our results are consistent across a variety of different proofreading schemes and metrics of performance, suggesting that they are inherent to the KPR mechanism itself rather than any particular model of molecular noise. Based on our results, we suggest alternative roles for KPR schemes such as multiplexing and combinatorial encoding in multi-ligand/multi-output pathways.

The segregation of chromosomes depends on the centromere. Most species are monocentric, with the centromere restricted to a single region per chromosome. In some organisms, the monocentric organization changed to holocentric, in which the centromere activity is distributed over the entire chromosome length. However, the causes and consequences of this transition are poorly understood. Here, we show that the transition in the genus
Cuscuta
was associated with dramatic changes in the kinetochore, a protein complex that mediates the attachment of chromosomes to microtubules. We found that in holocentric
Cuscuta
species, the
KNL2
genes were lost; the
CENP-C, KNL1
, and
ZWINT1
genes were truncated; the centromeric localization of CENH3, CENP-C, KNL1, MIS12, and NDC80 proteins was disrupted; and the spindle assembly checkpoint (SAC) degenerated. Our results demonstrate that holocentric
Cuscuta
species lost the ability to form a standard kinetochore and do not employ SAC to control the attachment of microtubules to chromosomes.
Broadening horizons in the diachronic and sociolinguistic study of Philippine English with the Twitter Corpus of
Philippine Englishes (TCOPE)
Authors: Gonzales Wilkinson Daniel Wong
Published: May 2023

This paper presents the Twitter Corpus of Philippine Englishes (TCOPE): a dataset of 27 million tweets amounting
to 135 million words collected from 29 cities across the Philippines. It provides an overview of the dataset, and then shows how
it can be employed to examine Philippine English (PhilE) and its relationship with extralinguistic factors (e.g. ethno-geographic
region, time, sex). The focus is on the patterns of variation involving four PhilE features: (1) irregular past tense morpheme
-t, (2) double comparatives, (3) subjunctive were, and (4) phrasal verb base
from. My analyses corroborate previous work and further demonstrate structured heterogeneity within PhilE, indicating
that it is a multifaceted and dynamic variety. TCOPE has shown itself to be useful for exploring both the “general” features of
contemporary PhilE and the different forms of variation within it. It contributes to a deeper understanding of Philippine
English(es) over time and in different social contexts.
‘It seems my enemy is about having malaria’

Published: May 2023

This study seeks to characterise the form of verbal irony common among Nigerians by identifying its motivation,
inherent properties, and communicative value. Data for this study comprised detailed field notes taken within the last five years
in contexts in which utterances occurred naturally. These were then tested among informants from diverse ethnic and linguistic
backgrounds at the University of Benin to determine the prevalence and motivation of the ironic utterances. In addition, 500
questionnaires were administered to a group of students and staff in the same institution. These were analysed using frequency
tables and simple percentages. Results support the claim that irony in this context is governed by a single cultural principle:
“You hurt yourself by admitting a negative situation.” Although the study draws heavily from the relevance-theoretic echoic
account, it seeks to reevaluate this account by suggesting that positive attitudes in negative situations are salient cultural
notions that underlie the echoic account in this context.
