Intention to use Peer-to-Peer (P2P) Lending: The Roles of Perceived Structural Assurance and Perceived Critical Mass
Authors: Widyanto Hanif Adinugroho , Syahrivar Jhanghiz , Genoveva Genoveva , Chairy Chairy
Published: June 2022

Peer-to-Peer (P2P) lending platform has enormous potential to improve financial inclusion for people in emerging countries. In this regard, the present study examined the predictors of continuance intention to borrow from P2P lending, especially as a Multi-Sided Platform (MSP) that relied heavily on critical mass to succeed. This research was among the first that analyzed the behavioral intention of P2P lending from the borrower’s perspective by expanding on the technology acceptance model (TAM) with two fundamental latent constructs for MSPs, namely perceived structural assurance and perceived critical mass. This quantitative study used Partial Least Square Structural Equation Modelling (PLS-SEM). Online questionnaires were spread to P2P lending borrowers (n =174) from all over Indonesia to measure the latent constructs. The result revealed that all the exogenous constructs did not have direct relationships with continuance intention to borrow. However, perceived structural assurance and perceived ease of borrowing indirectly affected the endogenous construct through perceived usefulness as the mediating variable. This study also offers some managerial implications for the P2P lending industry.
Analyzing Exchange Market Pressure Dynamics with Markov Regime Switching: The Case of Turkey
Authors: İlhan Ali , Akdeniz Coşkun , Özdemir Metin
Published: June 2022

This study analyzes the dynamics of exchange market pressure in Turkey by employing the Markov regime switching model for the period from January 2006 to December 2019. Our findings show that there are two regimes in the foreign exchange market, characterized as low- and high-pressure periods. The domination of the high-pressure regime in the sample period indicates that depreciation pressure prevails in the Turkish foreign exchange market. During this regime, the pressure is aggravated by the rising inflation, credit growth, and VIX, and the falling of short-term external debt. Thus, in the presence of capital flows, the preferences of policy authorities regarding price stability and growth determine the course of the pressure. When these policy choices favor credit-driven growth, depreciation pressure in the foreign exchange market is exacerbated through the current account deficit.

Published: June 2022

The pandemic of Obesity with its rapidly rising prevalence and burden on the health system, has become a major health concern. A variety of modifications including dietary, physical activity changes, behavioural in addition to pharmacotherapy interventions have been recommended for obesity management. Bariatric surgery has also been recommended for individuals with a Body Mass Index (BMI) exceeding or equal to 40 kg/m2 or in the range between 35 kg/m2 and 40 kg/m2 with a simultaneous significant comorbidity. Health practitioners often face the dilemma of patient selection when making a decision on bariatric surgical procedure suitability. This selection process is key to attaining good surgical outcome. Therefore, the input of a profecient multi- disciplinary team is crucial to the process. The following brief review is to point out the factors that influence the selection process. It describes the diverse bariatric surgical procedures available, discusses their efficacy, safety and complications rate, and emphasizes on the role of the MDT team in procedure selection according to patient characteristics

Published: June 2022

A felsőoktatási képzéseken megjelenő nagyarányú (általánosságban véve 30–40%-os) hallgatói lemorzsolódás súlyos problémákat okoz. Különösen érintett az informatikaoktatás, a legtöbb ország alapképzésének első két féléve a legkritikusabb: az intézmények elveszíthetik hallgatóik 60%-át. Vizsgálatunk célja annak feltárása, hogy a lemorzsolódás megelőzése érdekében bevezetett oktatási reform 2016 óta milyen mértékben befolyásolja a hallgatók egyetemen történő bennmaradását.

Programtervező informatikus hallgatók tanulmányi eredményeinek mintáját elemeztük 2010 és 2017 között az IRT-modell segítségével. A vizsgálatban 3673 egyetemi hallgató adatai szerepelnek.

Eredményeink szerint az oktatási reform után a legtöbb tantárgy teljesíthetőbbé vált, és az alacsonyabb képességű hallgatók is megpróbáltak vizsgát tenni. A matematikai témájú tantárgyak alacsonyabb nehézségi szinten is teljesíthetővé váltak, illetve alacsonyabb képességszintű hallgatók is vállalták a vizsgák megpróbálását, nem látták eleve kudarcnak a próbálkozást. A programozási/szakmai tárgyak nehezebbekké, komolyabb tárgyakká váltak, és megőrizték differenciálóképességüket. A hallgatók egyetemi előrehaladását segítő oktatási reform lehetővé tette a hallgatók tanulmányi teljesítményének javulását, ami arra enged következtetni, hogy érdemes beavatkozásokat eszközölni az egyes szakok képzési rendszerében.
Factors associated with seropositivity to Aino virus among sheep and goats in South Korea
Authors: Hwang Jeong-Min , Ga Yun Ji , Yeh Jung-Yong
Published: June 2022

Aino virus infection is responsible for epizootic and/or sporadic outbreaks of abortions, stillbirths and premature delivery among pregnant ruminants. The epizootiology of Aino virus infection is poorly defined in South Korea, therefore our aim was to assess its seroprevalence among sheep and goats. We also wanted to evaluate management and regional risk factors that might influence the frequency of infection. Between 2012 and 2013, 26 of 331 flocks (7.9%) and 139 of 915 heads (15.2%) were found serologically positive. In 2018, when samples were again collected in the same regions, 35 of 308 flocks (11.4%) and 89 of 735 heads (12.1%) showed serum-neutralising antibodies against Aino virus. Our results revealed that the age class and history of reproductive problems in the flocks are connected to an increased risk of being positive. The management risk factor attributes showed that preventive measures, such as the routine application of insecticide in farms, decreased the odds for seropositivity to Aino virus (OR = 0.453, P = 0.001). We observed a significant difference in the individual likelihood of being positive in the southern and western provinces with respect to that in the northern and eastern provinces, respectively (OR = 2.199, P < 0.001 and OR = 2.177, P < 0.001). The results of this study may serve as a basis for future epizootic studies on Aino virus infection in South Korea.

Bevezetés: A SARS-CoV-2 (súlyos akut légzőszervi szindrómát
előidéző koronavírus) okozta COVID–19 világszerte sajnálatosan nagy halálozással
jár. A fertőzés kimutatása elsősorban polimeráz-láncreakcióval (PCR) történik
élőben vagy a halál után, amely azonban nem ad információt arról, hogy a vírus
mely sejtekben, szövetekben van jelen. A SARS-CoV-2 tüske- és
nukleokapszid-proteinjeinek, valamint a vírus-ribonukleinsavnak (RNS) az
in situ kimutatása igazolhatja a vírus jelenlétét, valamint
adatot szolgáltathat annak direkt vagy indirekt sejtpusztulást okozó
mechanizmusáról. Jelenleg számos SARS-CoV-2-tüske- és -nukleokapszid
fehérjeellenes antitest van kereskedelmi forgalomban, melyek eltérő eredménnyel
képesek a megfelelő antigének kimutatására. Célkitűzés: A jelen
munka célja a megfelelő, megbízhatóan működő antitest kiválasztása volt.
Módszer: COVID–19-ben elhunyt 3 egyén formalinfixált,
paraffinba ágyazott, SARS-CoV-2-PCR-pozitív tüdejének anyagai, valamint
fertőzött placenta anonim módon jelölt mintái kerültek vizsgálatra, megfelelő
negatív kontrollal. Az immunhisztokémiai reakciók intenzitását és specificitását
hasonlították össze négy hazai orvostudományi egyetemi patológiai intézet
részvételével, különböző antitesteket és hígításokat alkalmazva. Az elvégzett
immunhisztokémiai reakciók szkennelt, kódolt metszeteken kerültek értékelésre,
majd az eredmények összesítése után statisztikai elemzésre.
Eredmények: A vizsgálatok alapján meghatározhatók voltak
azon antitestek, amelyek a jelölt hígításban és módszerrel megfelelő
intenzitású, megbízható eredményt adtak. Következtetés: A
vizsgálat alapot ad arra, hogy a SARS-CoV-2 egyes komponensei biopsziás/sebészi
anyagban és az elhunytak szöveteiben nagy pontossággal és reprodukálható módon
kimutathatók legyenek a COVID–19-ben megbetegedett, elhunyt egyének élőben vagy

Socio-professional Reintegration Services in the Era of the Covid-19 Pandemic in the Małopolska Region
Authors: Rychły-Mierzwa Anna
Published: June 2022

Background: The research issues concern the most important aspects of socio-vocational reintegration and rehabilitation services (e.g. instruments of support, barriers of service delivery, effects of activities), cooperation in local communities and the scope of institutional support.

Research objectives: The aim of this article is to present the most important implications of the coronavirus pandemic for socio-vocational reintegration services in reintegration units operating in the Małopolska Region.

Research design and methods: The material constituting the basis for analysis is mainly the results of a survey conducted by the Regional Centre for Social Policy in Kraków in the framework of cyclical monitoring of the social economy sector in the Małopolska Region. 73 Reintegration Units participated in this part of the study out of 122 active ones in the Małopolska voivodeship in 2020.

Results: The analysis makes it possible to conclude that the Covid-19 pandemic and related phenomena in the socio-economic sphere had a strong impact on the current functioning of reintegration units, reduced the scope of possible instruments for socio-occupational activation, which in turn had a negative impact on the results of support. The activities of the reintegration units, hampered by the pandemic, did not receive effective support from the public administration or local partners. The pandemic also limited the possibilities of cooperation between reintegration units in local communities.

Conclusions: The long-term effects of which will probably be felt for an unspecified period of time, in order to improve the quality and effectiveness of socio-occupational reintegration services provided by reintegration units.
Money Attitudes and Personal Finances During the COVID-19
Authors: Sadowska Magdalena
Published: June 2022

Background: Most of the research relates to previous major financial crises. The current coronavirus crisis is still ongoing, so the current analysis focuses primarily on people’s current preferences based on surveys.Research objectives: This work focuses on the analysis of the financial preferences of the group of people living and working in the Małopolskie Voivodeship in the last year. The choice of the form of makingpurchases, payments as well as savings and investments in the face of limitations caused by COVID-19 were analysed.Research design and methods: The adopted analytical-synthetic method is calculated to signal specific areas raising ethical doubts. Their exemplification leads to an attempt to define the key problem of modern finance, which is breaking away from the foundation of ethical values and, consequently, abandoning the common good as the social goal of all human activity.Results: The obtained results do not allow for the conclusion that in the analysed group, money attitudes significantly differentiate the financial choices of respondents during the restrictions related to COVID-19. The analysis of other factors related to the preferences of financial management allows for partial confirmation of hypothesis regarding the interest in online shopping and non-cash forms of payment has increased.Conclusions: The papers proved that the restrictions related to the coronavirus resulted in a significant increase in interest in new technologies, online shopping and modern payment methods.
Professional Subjectivity and Employers’ Trust in University Graduates As an Element of Labor Market Culture
Authors:   Financial University under the Government of the Russian Federation, Tyurikov Alexander , Vlasova Angelina ,   Financial University under the Government of the Russian Federation
Published: June 2022

The article deals with the problem of lack of trust between employers and graduates of higher educational institutions. The object-subject area of the article is the process of forming trust between university graduates and employers. The article substantiates the relationship between the economic culture of a person and his professional subjectivity. The theoretical and methodological basis of the study is the model of P. Shtompka's culture of trust. The hypothesis is tested that the professional subjectivity of a graduate affects the formation of a trusting relationship between him and his employer, and it is easier for a graduate with pronounced characteristics of professional subjectivity to build a trusting relationship with his employer. The application of the method of traditional analysis of documents allowed us to determine the main approaches to the study of the phenomenon of professional subjectivity: economic, legal, sociological and psychological. To test the hypothesis, both quantitative and qualitative methodology was used, in particular, methods of a questionnaire survey of graduates, a series of semi-formal interviews with employers. The use of these methods made it possible to study the influence of professional subjectivity of graduates on the trust of employers. According to the results of the study, it was possible to identify criteria of mutual trust for employers and for graduates, to compile a generalized portrait of a graduate who will cause distrust of the employer at the interview stage. In addition, it has been revealed what prevents these subjects from building trusting relationships and which practices that contribute to increasing trust between graduates and employers they see as more effective. The social types of graduates are identified and described: "interested", "earners" and "careerists", who are assessed by the level of formed trust in the employer at the intersection of the bases of professional orientation and trust-forming conditions. The article concludes with the results of hypothesis testing, as well as the directions of further scientific research and the practical significance of the conducted research.

Published: June 2022

The article is devoted to the publication of new monuments of rock art in the Kairakkol mountains and the Aksu river valley, located in the Aksu district of the Almaty region of the Republic of Kazakhstan. Geographically, the mountains are part of the Dzhungar Alatau system and are located in the eastern Semirechye. A description of three engravings and a group of three clusters of geometric signs is given. The drawings were discovered during exploration work in the vicinity of the Late Pazyryk burial ground of Tausamaly in 2020 and 2021 in the western spurs of the mountain Kairakkol, rocky outcrops of the Suuk plateau, and the mountain valley of the Aksu river. As a result of the area examination, it was possible to record a large number of petroglyphs dating back from the Bronze Age to the ethnographic time. Much of it definitely dates back to the early Iron Age and the Middle Ages. A large group of tamgas and tamga-like signs was found near the burial ground. Several petroglyphs stand out clearly among other petroglyphs, which have pictorial analogies in southern Siberia, eastern regions of Central Asia, and China. The list includes an anthropomorphic figure with a complex hairstyle or in a complex headdress, a rider about a two-horse, and a dragon. They are adjoined by three drawings, including geometric figures (simple lines, circular signs), knockouts of various types and shapes, holes, images of animals, and, in one case, a rider. They form complex compositions of ideogrammatic nature. A comparative historical analysis of the drawings shows the cultural ties of their creators with the nomads of Altai, the Minusinsk Basin, and, possibly, with the tribes of Northern China. The drawings are tentatively dated to the end of the 1st millennium BC or the border of two eras.
Nomadic Population of the Lower Volga Region Second Half of the 13th–14th Centuries According to the Results of Paleopathological Research
Authors:   Volgograd State University, Pererva Evgeniy
Published: June 2022

The paper presents the results of a study of paleopathological, age and sex features of nomads of the second half 13th–14th centuries from kurgan burials from the territory of the Lower Volga region. The skeletal material for the study is presented by skulls and bones of 81 postcranial skeleton human remains. Research methodology of studying paleoanthropological material includes examination of the series and skull using the standard assessment program of palepathological conditions of the bones of the postcranial skeleton developed by A.P. Buzhilova and an shortened program for assessing paleodemgraphic indicators. As a result of the study, it has been identified that a small number of children in burials and a high mortality of women at a young age was typical for the nomads of the 13th–14th centuries from the Lower Volga region. The early life stages were the most difficult for the nomads as evidenced by frequent occurrence in children and adults of stress markers in the form of “cribra orbitalia”, enamel hypoplasia, bones porosity of the vault and skull facial area. This fact proves that environmental and social factors influenced quality, and arguably life expectancy of the adult population. The diet of the population of 13th–14th centuries from the Lower Volga region included mostly meat and dairy products. The incidence assessment of injuries and of physical activity signs indicates that the nomads of the Golden Horde time led a peaceful lifestyle engaging in traditional forms of economic practices.
Non-Standard Early Bronze Burials Near the Yesaulovsky Aksay River. Some Issues of Cultural Genesis
Authors:   Volgograd State University, Dyachenko Alexander
Published: June 2022

The article dwells upon publication and analysis of materials from two unusual Early Bronze Age burials, dating back to the first half of the 3rd millennium BC, investigated by the Volgograd State University expedition in the southern part of the Volga-Don interfluve. The published archaeological complexes were discovered in the kurgan cemeteries located on the bank terraces of the steppe river called Yesaulovsky Aksay. A number of distinctive features made it possible to attribute these complexes to the late period of the Lower Volga Yamnaya culture. These kurgan burials stand out on the overall background of the Yamna culture burials due to the grave structure features, details of the burial rite and positions of the buried individuals. The bodies positions in the investigated burials are unusual. In one case, the dead body was arranged into a sitting position with the head turned towards the south. In another one, the dead body was segmented and then put into the typical crouched position on the side with the head turned towards the east. Both rites had come from another culture associated with the North Caucasus region which had a significant impact on the economy, social and ideological structure, burial practices of the population of the Lower Volga region and the adjacent territories of Russias southern steppes throughout the Early and Middle Bronze Ages.
New Finds of a Brick with Arabic Inscription from Hajji Tarkhan Hillfort
Authors:   Azov Historical Archeological and Paleontological Museum-Reserve, Iudin Nikita , Soloviov Damir ,   Astrakhan Museum-Reserve
Published: June 2022

The article is a publication of the brick discovered in the first half of the 20th century on the territory currently identified as a part of the Golden Horde known as Hajji Tarkhan, which is deposited in the funds of the Astrakhan Museum-Reserve. The fact that the finds entered the museum funds is connected with deliberate destruction of the settlement which had begun at the end of the 16th century. The latter is confirmed by historical sources. A well-preserved inscription in Arabic is a distinctive feature of the brick; the inscription is legible and possible to translate. Another characteristic of the inscription is that the letters were drawn without observing the norms of calligraphy on slightly dried clay or after the firing in the oven. The inscription includes three words, one of which is breaking on to the next line and forming a phrase that currently does not have exact analogies for translation. Nevertheless, a proposed translation option characterizes the inscription as one of the variations of the Quranic text formulas traditionally applied to various household items (vessels, candlesticks, pencil cases, etc.) since the 10th century. The nature of the unexpected finding in the lifting ground does not allow attributing it to any other construction on the Hillfort territory. Nevertheless, it was suggested that the brick was connected with the remains of a brick wall marked on the plan of the Shareniy Bugor hillfort drafted in 1924. The described and translated inscription is a new epigraphic source for the Golden Horde archeology. In addition, this is one of rare examples of the period when the text of the inscription was completely restored and translated.
Bronze Basin from the Kurgan No. 1 of the Group “Bogomol’nye Peski I” in the Lower Volga Region
Authors:   Astrakhan Museum Reserve, Timofeev Alexey , Treister Mikhail ,   Independent Researcher
Published: June 2022

The article dwells on the find of the bronze basin in the burial no. 5 of the kurgan no. 1 of the group “Bogomol’nye peski I” near the village of Nikolskoye, Enotaevsky District, Astrakhan Region. A belt-set of gold with turquoise inlays found in the region of the pelvic bones of a 40–45-year-old warrior, an iron dagger in a wooden scabbard with round-shaped iron overlays covered with gold foil and with turquoise inlays, and other finds allowed the author of the excavations to attribute the burial to the 1st–2nd centuries AD. It is obvious that the buried warrior belonged to the nomadic elite. A bronze basin, standing almost vertically, was leaning against the northern side of the grave-pit at its bottom. The analysis has shown that the basin belongs to a rare variant, till now unknown in Sarmatia. The closest parallel of its edge with a rim bent outwards and decorated with a band of Ionian kymation is a basin from the prince’s burial in Hoby on the island of Lolland in Denmark, usually dated in the first half of the 1st century AD. The peculiarities of the rosette design at the bottom of the basin associate it with a Tassinari S2300 type basin from Pompeii and some bronze paterae of the Eggers 154 / Nuber D type (Hagenow), which also indicates a probable dating no later than the first half or the middle of the 1st century AD. The basin demonstrates clear signs of deliberate damage. Not only the foot-ring and handles were lost, but the body itself was punched in several places in the form of wedge-shaped holes from the blows of a knife or dagger (?), which are very close in shape to the holes on the silver phalerae and the bowl of the Parthian circle of the second half of the 2nd – first half of the 1st century BC from the Trans-Volga region.

Matrix Variate Gaussian Mixture Distribution Steered Robust Metric Learning
Authors: Luo Lei , Huang Heng
Published: June 2022

Mahalanobis Metric Learning (MML) has been actively studied recently in machine learning community. Most of existing MML methods aim to learn a powerful Mahalanobis distance for computing similarity of two objects. More recently, multiple methods use matrix norm regularizers to constrain the learned distance matrixMto improve the performance. However, in real applications, the structure of the distance matrix M is complicated and cannot be characterized well by the simple matrix norm. In this paper, we propose a novel robust metric learning method with learning the structure of the distance matrix in a new and natural way. We partition M into blocks and consider each block as a random matrix variate, which is fitted by matrix variate Gaussian mixture distribution. Different from existing methods, our model has no any assumption on M and automatically learns the structure of M from the real data, where the distance matrix M often is neither sparse nor low-rank. We design an effective algorithm to optimize the proposed model and establish the corresponding theoretical guarantee. We conduct extensive evaluations on the real-world data. Experimental results show our method consistently outperforms the related state-of-the-art methods.
Learning Lexicographic Preference Trees From Positive Examples
Authors: Fargier Hélène , Gimenez Pierre-François , Mengin Jérôme
Published: June 2022

This paper considers the task of learning the preferences of users on a combinatorial set of alternatives, as it can be the case for example with online configurators. In many settings, what is available to the learner is a set of positive examples of alternatives that have been selected during past interactions. We propose to learn a model of the users' preferences that ranks previously chosen alternatives as high as possible. In this paper, we study the particular task of learning conditional lexicographic preferences. We present an algorithm to learn several classes of lexicographic preference trees, prove convergence properties of the algorithm, and experiment on both synthetic data and on a real-world bench in the domain of recommendation in interactive configuration.

Segmenting temporal data sequences is an important problem which helps in understanding data dynamics in multiple applications such as epidemic surveillance, motion capture sequences, etc. In this paper, we give DASSA, the first self-guided and efficient algorithm to automatically find a segmentation that best detects the change of pattern in data sequences. To avoid introducing tuning parameters, we design DASSA to be a multi-level method which examines segments at each level of granularity via a compact data structure called the segment-graph. We build this data structure by carefully leveraging the information bottleneck method with the MDL principle to effectively represent each segment.Next, DASSA efficiently finds the optimal segmentation via a novel average-longest-path optimization on the segment-graph. Finally we show how the outputs from DASSA can be naturally interpreted to reveal meaningful patterns. We ran DASSA on multiple real datasets of varying sizes and it is very effective in finding the time-cut points of the segmentations (in some cases recovering the cut points perfectly) as well as in finding the corresponding changing patterns.
ARC: Adversarial Robust Cuts for Semi-Supervised and Multi-Label Classification

Many structured prediction tasks arising in computer vision and natural language processing tractably reduce to making minimum cost cuts in graphs with edge weights learned using maximum margin methods. Unfortunately, the hinge loss used to construct these methods often provides a particularly loose bound on the loss function of interest (e.g., the Hamming loss). We develop Adversarial Robust Cuts (ARC), an approach that poses the learning task as a minimax game between predictor and "label approximator" based on minimum cost graph cuts. Unlike maximum margin methods, this game-theoretic perspective always provides meaningful bounds on the Hamming loss. We conduct multi-label and semi-supervised binary prediction experiments that demonstrate the benefits of our approach.
Bayesian Functional Optimization

Published: June 2022

Bayesian optimization (BayesOpt) is a derivative-free approach for sequentially optimizing stochastic black-box functions. Standard BayesOpt, which has shown many successes in machine learning applications, assumes a finite dimensional domain which often is a parametric space. The parameter space is defined by the features used in the function approximations which are often selected manually. Therefore, the performance of BayesOpt inevitably depends on the quality of chosen features. This paper proposes a new Bayesian optimization framework that is able to optimize directly on the domain of function spaces. The resulting framework, Bayesian Functional Optimization (BFO), not only extends the application domains of BayesOpt to functional optimization problems but also relaxes the performance dependency on the chosen parameter space. We model the domain of functions as a reproducing kernel Hilbert space (RKHS), and use the notion of Gaussian processes on a real separable Hilbert space. As a result, we are able to define traditional improvement-based (PI and EI) and optimistic acquisition functions (UCB) as functionals. We propose to optimize the acquisition functionals using analytic functional gradients that are also proved to be functions in a RKHS. We evaluate BFO in three typical functional optimization tasks: i) a synthetic functional optimization problem, ii) optimizing activation functions for a multi-layer perceptron neural network, and iii) a reinforcement learning task whose policies are modeled in RKHS.

The present study investigates the self-healing functionality of e-glass unidirectional fiber-reinforced epoxy resin, based on a hollow glass fiber approach under flexural and impact loading. The planned self-healing fiber-reinforced composite constitutes epoxy resin (Lapox ARL-125 + AH-367), e-glass fibers with 0° orientation, embedded hollow glass fabric (HGF) filled with a curing agent (Lapox L-552/K-552), which provides a self-healing functionality. The developed composite is tested on the virgin, damaged, and healed conditions for the various healing periods (1, 2, and 3 days), and recovered flexural, impact strength and subsequent healing efficiency are studied. On day three, the optimum flexural strength achieved is 851.17 N/mm2, with a healing efficiency of 74.53% when subjected to quasi-static load. Similarly, the optimum impact energy absorbed is 4439.26 J/m, and impact strength achieved is 445.88 kJ/m2, with a healing efficiency of 55.58% when subjected to impact load. The results show that developed self-healing composites may provide excellent flexural and impact properties for marine structural applications.
REDUCING STUDENT ANXIETY IN ONLINE TERTIARY MUSIC EDUCATION THROUGH THE APPLICATION OF UNIVERSAL DESIGN FOR LEARNING
Authors: Blackburn Alana , McGrath Naomi
Published: June 2022

Online teaching and learning are not new, nor are they new to tertiary music education. While an "anytime, anywhere" attitude and flexible study suits some learners, for others this is a contributing factor to student anxiety and attrition. This article explores the relationship between student anxiety in online learning and universal design for learning (UDL), and how UDL principles can be applied to reduce anxieties about musical performance in an online class. It explores common barriers for students in the online environment and offers strategies for sustainable learning design in a way to accommodate students before, during, and after unit completion. As well as designing with UDL, this study includes approaches to modeling accessible learning activities in order to provide students with the support they need to perform in an online space, meet learning objectives, and reduce attrition.
Impact of tax aggressiveness on the profitability of publicly traded companies listed on B3

The practice of tax aggressiveness aims to alleviate the high cost of taxes caused by the complexity of tax legislation, aims to reduce tax expenditures and maximize the organizations' performance. The present study analyzes the impact of tax aggressiveness on the profitability of publicly traded companies listed on B3 in the period from 2016 to 2020, since in the Brazilian context, evidence on the relationship between this practice and the companies’ profitability is still limited. The final study sample consisted of 204 Brazilian companies and the proxies used to measure tax aggressiveness were the total Book Tax Difference (BTD) and Effective Tax Rate (ETR). Regarding the variables of profitability, the return on investments, return for shareholders and operational activities were observed. The analysis was performed using descriptive statistics, multiple regressions (with random effects) and quantiles, and the results found did not show consensus between the proxies. While the BTD points out that the greater the tax aggressiveness, the greater the profitability, the ETR shows an inverse relationship. As tax aggressiveness proxies do not show consensus in the results, it was not possible to state that higher levels of tax aggressiveness increase the profitability of publicly traded companies listed on B3. Thus, the empirical evidence allows reflections on the use of tax aggressiveness in Brazil and the managers’ decision-making.

RAIL PASSENGER COMMUNICATIONS IN RUSSIAN MILLIONAIRE CITIES: SCALE, SPECIFICS, POSSIBILITIES OF TRANSFORMING THE CITY ENVIRONMENT
Authors:   Perm State University, Merkushev Sergey A.
Published: June 2022

The successful evolution of the millionaire cities’ environment is impossible without the availability of modern off-street transport that meets modern standards of speed, safety, ergonomics, and comfort. In Russia, only one type of off-street urban transport – rail transport – is available in all millionaire cities without exception. Therefore, its development is the fastest way to improve the transport situation and enhance the connectivity of urban space. In the paper, we estimate the scale of the rail transport development in all Russian cities with over a million residents (except Moscow and St. Petersburg), analyze the orientation of the rail transport systems towards solving the problems of urban transportation and saving the passengers’ time. The calculation of the integral indicator, covering six specific indicators, revealed a significant differentiation of cities, which showed further increase when the method was supplemented with three indicators characterizing the interaction between different routes of rail transport, as well as with the subway and external (air) transport. We have identified cities whose best practices must be applied in order to avoid aggravation of transport problems that negatively affect the quality of the urban environment and the citizens’ freedom of choice.

The paper presents the results of research into the hydrological features and geoecological state of small watercourses in the polder territories of the Kaliningrad region. The work is focused on the largest polder massif of the region located on the territory of the Neman lowland in the Slavsky urban district. There was carried out geoecological monitoring of surface watercourses in the following seasons: summer (July 15, 2020), autumn (October 15, 2020), winter (February 3, 2021), and spring (March 27, 2021). For the monitoring we selected watercourses that in their totality could characterize the river network of the polder massif as a whole: the rivers Zlaya, Shlyuzovaya, Nemoninka, and Osa. Subsequently, water samples were taken for hydrochemical analysis, and the hydrometric characteristics of the rivers were measured at background and control points. In order to more objectively characterize the hydrological features of the river network, in addition to the results obtained during the monitoring, we used data on long-term hydrological observations. The research provides information on the state of the watercourses and the influence of anthropogenic and natural factors on them. Monitoring of the geoecological state has shown that they are to a greater or lesser extent susceptible to pollution and, in general, have a ‘bad quality’ water class. The main pollutants identified in the course of research were: nitrites, ammonium, phosphates, total iron, and oil products. There are also inconsistencies with the norms of maximum permissible concentrations in terms of biological consumption of oxygen and dissolved oxygen that are noted during the period of activity of living organisms. The geoecological state was found to be linked to the water regime, weather conditions, natural and agricultural cycles. A non-standard course of the water regime phases was noted, namely: autumn-winter floods, not very pronounced high water, and summer low water. The current situation of the river network can be characterized as unfavorable but still having a potential for correction due to the properly selected environmental protection measures.

Cultural and historical recreational resources (along with natural ones) are the basis for the formation of tourist and recreational potential and an integral element of tourist and recreational systems. There are different approaches to the assessment of cultural and historical resources as an element of the tourist service management. In the absence of a unified methodology, these approaches are often based on the evaluation of both quantitative and qualitative indicators of sites. The practical part of the presented study deals with the assessment the tourist-recreational potential of the Krasnodar region in terms of cultural and historical sites located therein. The territory of the region as a whole demonstrates rich potential, while the distribution of cultural and historical resources is characterized by heterogeneity. The main focus of the study is on the region’s most developed tourist and recreational areas where cultural and historical sites of various types are concentrated: the Caucasian-Black Sea area, North-Caucasian, Mountain-Caucasian, and Azov ones. The paper analyzes how much these territories are saturated with cultural and historical sites of federal, regional and local significance, calculates the density of the sites, and studies the possibility of using those. Based on the research findings, cartographic schemes were compiled. The main result of the study is the application of the authors’score and factor methodology in assessing cultural and historical sites, which confirmed the leading positions of the Black Sea coastal resorts (Anapa, Novorossiysk, Gelendzhik, and Sochi) and the regional center Krasnodar in the ranking of tourist and recreational centers of the region.
