Published: December 2023

This study aimed to assess the feasibility of diagnosing secondary pulmonary fungal infections (PFIs) in patients with hematological malignancies (HM) using computerized tomography (CT) imaging and a support vector machine (SVM) algorithm. A total of 100 patients with HM complicated by secondary PFI underwent CT scans, and they were included in the training group. Concurrently, 80 patients with the same underlying disease who were treated at our institution were included in the test group. The types of pathogens among different PFI patients and the CT imaging features were compared. Radiomic features were extracted from the CT imaging data of patients, and a diagnostic SVM model was constructed by integrating these features with clinical characteristics. Aspergillus was the most common pathogen responsible for PFIs, followed by Candida, Pneumocystis jirovecii, Mucor, and Cryptococcus, in descending order of occurrence. Patients typically exhibited bilateral diffuse lung lesions. Within the SVM algorithm model, six radiomic features, namely the square root of the inverse covariance of the gray-level co-occurrence matrix (square root IV), the square root of the inverse covariance of the gray-level co-occurrence matrix, and small dependency low gray-level emphasis, significantly influenced the diagnosis of secondary PFIs in patients with HM. The area under the curve values for the training and test sets were 0.902 and 0.891, respectively. Therefore, CT images based on the SVM algorithm demonstrated robust predictive capability in diagnosing secondary PFIs in conjunction with HM.

Published: December 2023

Objectives

An isotope dilution liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS)-based candidate reference measurement procedure (RMP) was developed and validated to accurately measure serum and plasma concentrations of carbamazepine.

Methods

Quantitative nuclear magnetic resonance (qNMR) spectroscopy was used to determine the absolute content of the reference material, ensuring its traceability to SI units. The separation of carbamazepine from potential interferences, whether known or unknown, was achieved using a C18 column. A protein precipitation protocol followed by a high dilution step was established for sample preparation. Assay validation and determination of measurement uncertainty were performed in accordance with the guidelines of the Clinical and Laboratory Standards Institute, the International Conference on Harmonization (ICH), and the Guide to the Expression of Uncertainty in Measurement (GUM). In order to demonstrate equivalence to the already existing RMP a method comparison study was performed.

Results

The RMP was proven to be highly selective and specific with no evidence of a matrix effect, allowing for quantification of carbamazepine within the range of 0.800–18.0 μg/mL. Intermediate precision and repeatability (n=60 measurements) was found to be <1.6 % and <1.3 % over all concentration levels and independent from the matrix. The relative mean bias ranged from −0.1 to 0.6 % for native serum and from −0.3 to −0.1 % for Li-heparin plasma levels. The measurement uncertainties for single measurements and target value assignment were found to be <1.8 % and <1.3 %, respectively. Method comparison showed a good agreement between the Joint Committee of Traceability in Laboratory Medicine (JCTLM) listed RMP and the candidate RMP resulting in a Passing–Bablok regression equation with a slope of 1.01 and an intercept of −0.01. The bias in the patient cohort was found to be 0.9 %.

Conclusions

We present a novel LC-MS/MS-based candidate RMP for carbamazepine in human serum and plasma which provides a traceable and reliable platform for the standardization of routine assays and evaluation of clinically relevant samples.

Published: December 2023

Objectives

Data generation in clinical settings is ongoing and perpetually increasing. Artificial intelligence (AI) software may help detect data-related errors or facilitate process management. The aim of the present study was to test the extent to which the frequently encountered pre-analytical, analytical, and postanalytical errors in clinical laboratories, and likely clinical diagnoses can be detected through the use of a chatbot.

Methods

A total of 20 case scenarios, 20 multiple-choice, and 20 direct questions related to errors observed in pre-analytical, analytical, and postanalytical processes were developed in English. Difficulty assessment was performed for the 60 questions. Responses by 4 chatbots to the questions were scored in a blinded manner by 3 independent laboratory experts for accuracy, usefulness, and completeness.

Results

According to Chi-squared test, accuracy score of ChatGPT-3.5 (54.4 %) was significantly lower than CopyAI (86.7 %) (p=0.0269) and ChatGPT v4.0. (88.9 %) (p=0.0168), respectively in cases. In direct questions, there was no significant difference between ChatGPT-3.5 (67.8 %) and WriteSonic (69.4 %), ChatGPT v4.0. (78.9 %) and CopyAI (73.9 %) (p=0.914, p=0.433 and p=0.675, respectively) accuracy scores. CopyAI (90.6 %) presented significantly better performance compared to ChatGPT-3.5 (62.2 %) (p=0.036) in multiple choice questions.

Conclusions

These applications presented considerable performance to find out the cases and reply to questions. In the future, the use of AI applications is likely to increase in clinical settings if trained and validated by technical and medical experts within a structural framework.

Published: December 2023

BaTi5O11 nanocrystals were synthesized by a hydrothermal method, and the effect of oleic acid (OA) in the Ba–Ti precursors on morphologies of BaTi5O11 nanocrystals was investigated. As the OA/(Ba2+ + Ti4+) molar ratio ranged from 0 to 8, single-phase BaTi5O11 nanocrystals were synthesized at 260 °C for 20 h. When OA reagent was not added to the precursors, rice-like BaTi5O11 nanocrystals were obtained. As the OA/(Ba2+ + Ti4+) molar ratio was 1, elongated lath-like BaTi5O11 nanocrystals were synthesized with the width of about 130 nm, thickness of about 50 nm and length of about 400 nm. With increasing the OA/(Ba2+ + Ti4+) molar ratio from 1 to 6, the grain size of elongated lath-like BaTi5O11 nanocrystals gradually decreased. As the OA content increased, the amount of adsorbed OA molecules on the surface of Ti(OH)
x
nucleus increased and hindered the reaction of Ba2+ ions with Ti(OH)
x
nucleus, which caused the decrease of grain size of lath-like BaTi5O11 nanocrystals. When the BaTi5O11 nanocrystals were synthesized at OA/(Ba2+ + Ti4+) molar ratio of 1, they had the largest dielectric constant (ε
r) of 40.9 at 5 GHz.

Authors: Kim Hannah , Gao Yiwei , Moran Ethan , Howle Annyn , McSherry Sean , Cira Spencer , Lenert Andrej
Published: December 2023

We present a radiative cooling material capable of enhancing albedo while reducing ground surface temperatures beneath fielded bifacial solar panels. Electrospinning a layer of polyacrylonitrile nanofibers, or nanoPAN, onto a polymer-coated silver mirror yields a total solar reflectance of 99 %, an albedo of 0.96, and a thermal emittance of 0.80. The combination of high albedo and high emittance is enabled by wavelength-selective scattering induced by the hierarchical morphology of nanoPAN, which includes both thin fibers and bead-like structures. During outdoor testing, the material outperforms the radiative cooling power of a state-of-the-art control by ∼20 W/m2 and boosts the photocurrent produced by a commercial silicon cell by up to 6.4 mA/cm2 compared to sand. These experiments validate essential characteristics of a high-albedo radiative-cooling reflector with promising potential applications in thermal and light management of fielded bifacial panels.

Authors: Neira-Placer Paula , Visiers Ana
Published: December 2023

Introducción: Los canales de YouTube dirigidos a un público infantil actualmente tienen audiencias millonarias. El que estos contenidos no estén sometidos a control y sean creados frecuentemente por personas no expertas en comunicación o educación infantil además de la vulnerabilidad de la audiencia hace que su revisión y estudio tenga importancia. Un aspecto relevante es el tipo de valores que son transmitidos, en especial, cuando los contenidos muestran situaciones de juego, momento en el que los niños generan emociones positivas y son más influenciables. Conocer cómo se muestran las marcas que comercializan juguetes permitirá tomar medidas de control. Metodología: La investigación realizada es un estudio de caso en el que se han revisado los contenidos publicados durante 24 meses del canal de YouTube Vlad y Niki desde su apertura hasta principios de 2021. Resultados: El estudio apunta que debido a la frecuencia de aparición de valores como la diversión, la solidaridad, la violencia o el refuerzo de los estereotipos de género en las situaciones de juego estos terminan por incidir en los contenidos generales del canal. También se encuentra una cierta conexión entre los distintos tipos de valores y las categorías de juguetes y las marcas, en especial, aquellas que patrocinan contenidos. Discusión y conclusiones: Se proponen recomendaciones con el objetivo de que las compañías jugueteras se visibilicen dentro de estos canales de forma más responsable.
Croatian hotel managers’ attitudes towards environmental management systems: perceived benefits and barriers
Authors: Šlogar Helena , Hrvatin Stella
Published: December 2023

Researchers have pointed out significant adverse environmental impacts of the hotels and suggested environmental management systems (EMS) as a solution for identifying, managing and mitigating those impacts. EMS are adopted by the top management members based on perceived benefits and implementation barriers. The purpose of this study is to explore the attitudes of general managers from Croatian hotels about perceived benefits of and barriers to EMS implementation. Data was collected with online questionnaires from April to June 2021. Sample included 32 general managers, representing hotels from Istria, Kvarner, North, Central and South Dalmatia. Collected data was analysed using descriptive statistics. Croatian hotel managers perceive improved reputation and sustainable resource governance, followed by cost reductions as the main benefits of EMS. Administrative burden, lack of human resources and lack of knowledge are perceived as the most significant barriers for managers of hotels with implemented EMS, while implementation costs, lack of human resources and infrastructure changes are perceived as considerable barriers by managers from hotels without EMS. The results of this study provide an insight about the perceived benefits and barriers of EMS in Croatian hospitality sector contributing to the field by testing the findings of previous research in different context.
Internal Audit in Public Hospitals: the case of Greece
Authors: Grose Chris , Petsi Myrto , Kalialakis Ioannis , Talias Michael
Published: December 2023

Internal control is of utmost importance for effective corporate governance, particularly in public hospitals aiming for modernization in the Greek framework. Internal audit functions enhance transparency, enforce accountability, and ensure compliance with societal values, bolstering public trust. This study delves into the implementation of internal control in Greek public hospitals, considering factors like size, structure, and operational intricacies. We explore the regulatory framework, procedures, scope, and objectives, while interviewing auditing experts for insights into challenges and opportunities. Findings reveal procedural dominance in current implementation of the Law. Focus on accounting neglects crucial functional departments. The audit committee's role and composition raise independence concerns. Understaffing further hampers operations. A significant weakness appears in the independence of the audit. Internal auditors report to the hospital administrator and participate in the audit committee. The appointment and remuneration of auditors is not based on the auditor's competence and suitability, but on a cost basis. The question therefore arises as to whether the auditor performs the duties objectively and impartially in accordance with the International Institute of Internal Auditors' standards. Furthermore, regarding the research question on the role of the internal auditor and the treatment by auditees, there has been a significant improvement as evident by the respondents’ answers.
On the index of special perfect polynomials
Authors: Gallardo L.H.
Published: December 2023

We give a lower bound of the degree and the number of distinct prime divisors of the index of special perfect polynomials. More precisely, we prove that $\omega(d) \geq 9$, and $\deg(d) \geq 258$, where $d := \gcd(Q^2,\sigma(Q^2))$ is the index of the special perfect polynomial $A := p_1^2 Q^2$, in which $p_1$ is irreducible and has minimal degree. This means that $ \sigma(A)=A$ in the polynomial ring ${\mathbb{F}}_2[x]$. The function $\sigma$ is a natural analogue of the usual sums of divisors function over the integers. The index considered is an analogue of the index of an odd perfect number, for which a lower bound of $135$ is known. Our work use elementary properties of the polynomials as well as results of the paper [J. Théor. Nombres Bordeaux 2007, 19 (1), 165$-$174].
Magnetic moment of Mn2+ ions that are responsible for the ferromagnetic properties of ZnO:Mn nanocrystals
Authors: Kovalenko O.V. , Vorovsky V.Yu.
Published: December 2023

The calculation of the magnetic moment of Mn2+ ions in ZnO:Mn (2 at%.) nanocrystals obtained by ultrasonic pyrolysis of aerosol which are responsible for their ferromagnetic properties is given. In order to investigate the influence of structural defects on the value of magnetic moment the samples were heat treated in air. The calculation was performed on the basis of the analysis of magnetization curves and EPR spectra. It was shown that the defective state of ZnO:Mn nanocrystals has a significant effect on the magnetic moment. The values of magnetic moment for the synthesized sample significantly exceed the values of magnetic moment compared to similar nanocrystals obtained by other methods. The assumption is made that this result is due to the presence of an additional component in the magnetization of the defective samples. In addition to the paramagnetism of Mn2+ ions, there may be the paramagnetism of the defective shell of ZnO:Mn nanocrystals. After the elimination of structural defects by heat treatment of samples in air and in a gas mixture with hydrogen, the magnetic moment for Mn2+ ions, which form the ferromagnetic properties of nanocrystals, was determined. The value of this magnetic moment is 0.02µB, where µB is the Bohr mangiton. Such ions, according to the model of bound magnetic polarons, are part of ferromagnetic clusters and take part in the formation of the ferromagnetic properties of the samples.

Keywords: magnetic moment, nanocrystals, ultrasonic aerosol pyrolysis, heat treatment, hydrogen.

Authors: Yushchuk S.I. , Yur`ev S.O. , Moklyak V.V.
Published: December 2023

The ferrogarnet structures consisting from one- to three- layers of monocrystalline yttrium-iron garnet Y3Fe5O12 (YIG) films, two- layered YIG - La,Ga:YIG and two- layered {Y,Sm,Lu}3(Fe,Ga)5O12 -YIG  structures were grown by liquid-phase epitaxy (LPE) method on gadolinium - gallium garnet Gd3Ga5O12 (GGG) substrates of (111) orientation. The obtained layered ferrogarnet structures were studied by the methods of ferromagnetic resonance (FMR) and magnetostatic wave (MSW) interference. The two- and three- layered YIG structures have a wide FMR line width (∆H). For the three- layered YIG structures with the total thickness of 68-102 μm ∆H = 5,7- 11,5 Oe. The line width ∆H = 0,34 – 1,22 Oe correspond to the two- layered (Y,Sm,La)3(Fe,Ga)5O12 – YIG structures with thicknesses from 3 to 65 μm. Individual layers in all structures are characterized by similar or different saturation magnetizations (4πMs).The frequency MSW separation in the YIG - La,Ga:YIG layered structure was observed. It was shown that the propagation losses of MSW in one- and two- layered structures increase with decreasing wavelength of MSW and transition to a two- layered structure.
AMBIENTE, SAÚDE E DIREITOS HUMANOS
Authors: Fonseca Vania
Published: December 2023

La cuestión de degradación del medio ambiente y de los derechos humanos implica necesariamente el proceso de globalización económica que es responsable del aumento de las desigualdades socioeconómicas entre los países y regiones, y el medio ambiente, incluido el entorno social. También se facilitó la globalización de la enfermedad y el regreso de las pandemias. Sin embargo, vinculada a una mayor contaminación a nivel planetario, son grandes los reflejos sobre la producción de alimentos, seguridad alimentaria y el acceso a los servicios esenciales a la dignidad humana. Este conjunto de factores del entorno natural y social ha dado lugar a reacciones de los países en desarrollo, que se sienten excluidos de la toma de decisiones con respecto a la senda de la globalización y heridos en la promoción de los derechos humanos.
desembrulhar das asas da guará vermelha
Authors: Schmidt Ferrão Ana Carolina , Araújo Barberena Ricardo
Published: December 2023

A presente pesquisa busca analisar a representação da prostituição feminina na obra de Maria Valéria Rezende, "O voo da guará vermelha” (2014). O romance traz a cuidadosa construção da protagonista Irene, através de um viés subjetivo, subvertendo as narrativas usuais acerca das personagens que exercem trabalho sexual. O foco da análise é o processo de construção do "eu" da personagem prostituta, levando em consideração as características que corroboram com o desenvolvimento da identidade. Ao decorrer do texto serão averiguados variados aspectos que contribuem para a ruptura do estereótipo na representação literária, questões essas que envolvem o corpo feminino, a transformação em mercadoria e demais rótulos imputados às trabalhadoras sexuais, indivíduos pouco célebres do submundo erótico. Nesse sentido, o romance abordará o estereótipo como âncora para sua própria anulação, expondo assim suas raízes e contradições. Já os elementos que sustentam a identidade da personagem, por sua vez, opõem-se à força do estereótipo e cimentam sua humanização. A autora utiliza recursos como a memória e a narrativa intimista, que buscam reaver o protagonismo da prostituta, figura estigmatizada tanto na sociedade quanto na literatura, e seu reconhecimento como sujeito. Por meio de lembranças e fluxos de consciência, a identidade da personagem é constituída, expondo seus desejos, sonhos, sentimentos e medos, sem que haja uma propensão a vitimizações ou condenações. Dessa forma, nos debruçaremos sob as manifestações de uma representação subjetiva, demonstrando como ela confronta intrinsecamente o estereótipo. Para tal, nos ampararemos em autores referências como Homi Bhabha, Pierre Bourdieu, Aleida Assmann e Judith Butler.

Published: December 2023

Introduction: Chemical pollution represents a great concern to aquatic organisms, especially fish. Metals enter the aquatic environment from a variety of sources, including natural biogeochemical cycles and anthropogenic sources such as industrial and residential effluents, mining and atmospheric sources. Objective: To describe the Eustrongylides sp. larvae and the interaction with their fish hosts as indicators of mercury (Hg) contamination in the Brazilian Amazon, and the distribution of Hg in the internal organs of fish species Hoplias malabaricus and Pygocentrus nattereri collected in oxbow lakes on the Tapajós River, in the municipality of Santarém, in the state of Pará. Methods: Total Hg was analyzed using the Direct Hg Analyzer - DMA-80. Concentrations of Hg in Eustrongylides sp. were compared with those found in the tissues/organs of the hosts H. malabaricus and P. nattereri. Hg concentrations in the host/parasite system were statistically compared using Principal Component Analysis. The bioconcentration factor (BCF) was calculated to assess the bioaccumulation capacity of metals in Eustrongylides sp. larvae, comparing the concentration of Hg in the parasite with that accumulated in the musculature of infected hosts. Results: Hg concentrations in all tissues/organs analyzed were higher in the parasitic species Eustrongylides sp. larvae when compared with those found in tissues/organs of H. malabaricus and P. nattereri. There was an inversely proportional relationship, showing that when Eustrongylides sp. larvae are present, the concentration in the parasite is higher than in the musculature of host fish H. malabaricus and P. nattereri. The BCF of Hg was found by comparing Eustrongylides sp. larvae/H. malabaricus muscle and was observed during a flood (BCF Hg = 15 364). Conclusions: The results confirm the greater bioaccumulative capacity of Eustrongylides sp. compared to its host. The data indicated the viability of using Eustrongylides sp. larvae in biomonitoring programs. It is worth mentioning that fish samples for Hg analysis must be free of parasites since their presence can alter the results.
Drivers of moral hazard in banks
Authors: Jović Željko
Published: December 2023

The objective of this research is to identify factors that determine the moral hazard in banks by using discrete choice models (probit and logit regression). A specially constructed indicator was used to quantitatively assess moral hazard as the average difference between the better rating of a client in a bank and the most conservative rating of the same client in the banking sector. This is an example where moral hazard manifests itself as the tendency of management in banks to underestimate credit risk. The results showed that state-owned banks and foreign privately-owned banks with evident problems at the level of their headquarters had higher values of this quantitative indicator of moral hazard. Also, banks whose financial result and capital are highly sensitive to a small increase in non-performing loans, as well as banks that at any time in the observed period had a problem with meeting regulatory capital requirements, showed a greater propensity to moral hazard, as measured by this indicator. In the above cases, in the absence of quality corporate governance, management in banks tends to show performance better than it actually is. The obtained results for Serbia in comparison with the previous research give the possibility to quantitatively confirm additional specific factors important for explaining moral hazard (composite variable of the type of ownership and capital restrictions, variables that perform only the transmission of certain forms of management behaviour, size, capital and profit sensitivity, credit risk level, etc.), in addition to the common factors of moral hazard, such as the type of ownership in the bank, capital restrictions, etc.
Debt Flexibility
Authors: Bidder Rhys , Crouzet Nicolas , Jacobson Margaret M. , Siemer Michael
Published: December 2023

This paper documents new facts on the modification of bank loans using FR Y-14Q regulatory data on C and I loans. We find that loan-level modifications of key contractual terms, such as interest and maturity, occur at least once for 41% of loans. Cross sectional differences in modifications are substantial and amplified by borrower distress. Relative to single-lender loans, syndicated loans are 1.5 times more likely to be modified and interest rate changes are twice as likely. Our findings call into question whether 1) creditor dispersion makes loan modifications more challenging and 2) relationship lending between banks and small borrowers creates more scope for flexibility when borrower-level conditions change.

Issues of Transition from FSBU to IFRS: Current Assets
Authors: Levchenko Natalya , Borodina Daria , Chistyakova Liliya
Published: December 2023

In order to interact with foreign partner organizations, Russian companies are supposed to submit reports in accordance with international financial reporting standards. The relevance of the study lies in the fact that the Russian accounting standards and international financial reporting standards are significantly different in their application in accounting. The article identifies main features and problems of business transition from the FSBU to IFRS. A comparative analysis of current assets such as stocks, receivables, financial investments, cash, was conducted. Problems and ways of their elimination were pointed out. The advantages of transition to IFRS were defined. Reporting information compiled in accordance with international financial reporting standards is more transparent, complete and detailed compared to the Russian accounting standards. When processing reports, a lot of complex calculations take place, and a large amount of information is analyzed in a fairly short time, thus, the probability of making an error is very high. Therefore, it is rational to carry out a set of verification procedures in order to provide reliable data in the statements made in accordance with international financial reporting standards. In the process of the control procedure, it is necessary to assess whether adjustments in the company's reporting have been correctly applied and check estimated accuracy of the calculations performed.
On the Question of History and the Current Situation of Cruise Tourism on Lake Baikal
Authors: Rzhepka Elina , Golovchenko Tatiana , Novichkova Tatiana
Published: December 2023

The article examines the history of the development of cruise tourism on Lake Baikal, provides data on the current situation with the cruise fleet. The largest owner of vessels of all categories is the East Siberian River Shipping Company. It operates on Lake Baikal and the Angara river and has two components such as a cargo fleet and a high-speed passenger fleet. In 2003, the first cruise company on the Baikal was registered within the framework of the Eastland Group of Companies and the first three-deck motor ship Nikolay Yeroshchenko went on its first cruise in 2004. This activity is quite capital-intensive and labor-intensive with a lot of restrictions and difficulties associated with regulatory authorities, with a short navigation period, and with the need to resolve the issue of "wintering" of ships during the freezing over of the lake. Nowadays, the fleet on Lake Baikal has more than 200 large and about 11 thousand small vessels. In addition to specially-designed for tourist purposes, there is also a category of research vessels. Special attention is paid to the difficulties with providing personnel for the crew and maintenance personnel, since the work has a prominent seasonal character. The authors draw attention to the impact of this type of tourism on the environment and emphasize the main types of impact. The problem of cruises is not only that there are not enough ships or they are outdated, but in the absence of comfortable berthing facilities throughout Lake Baikal.
The Institute of Commercial Concession in Russia and Franchising Abroad: Correlation, Problems of Legal Regulation and Options of their Solution
Authors: Belousov Vladimir , Bayanova Zhanna
Published: December 2023

The successful development of entrepreneurial activity requires the availability of economic, industrial and organizational potential, it is associated with certain risks that can be minimized by concluding a commercial concession agreement. The ongoing political events have shown how changes can occur rapidly in all spheres of public life. These circumstances can become a springboard for development, in which a commercial concession agreement can act as an assistant. The article is devoted to the problems of regulation of a commercial concession contract in Russian law, a comparative analysis of Russian legislation and legislation of foreign countries concerning the regulation of the issues under consideration is carried out. The correlation of the concepts of "commercial concession agreement" and "franchising" is made. The etymology of the term "commercial concession" fixed in the Civil Code of the Russian Federation is investigated and its connection with the term "concession agreement" is analyzed. The necessity of presenting strict requirements inherent in the law of some foreign countries to the parties of the contract is denied. The amendments to the Russian civil legislation are reasoned. In order to set a balance between domestic and foreign norms, it is offered to replace the title of Chapter 54 of the Civil Code of the Russian Federation "Commercial Concession Agreement" with "Franchise Agreement". The obligations of the copyright holder to assist and control the quality of goods, works, and services under the contract should be formulated in the law in an imperative form. The necessity to supplement the Civil Code of the Russian Federation with a norm granting a user the right of the repudiation from the contract is justified. It also seems appropriate to supplement the articles regulating the obligations of the parties with provisions on disclosure of information by them at the pre-contractual stage of the agreement.
Systematization of the Factors Influencing the Activity of Private Investors in the Russian Securities Market, in the Context of Professional Mediation
Authors: Zvyagintseva Natalya , Ovchinnikova Ksenia
Published: December 2023

The article outlines the problem of mobilizing the resource potential of private investors through the mechanisms of professional mediation in the securities market. The significance of the processes of transformation of private savings into investments for the purposes of ensuring economic growth and the stability of the economic system of the Russian Federation is beyond doubt. This aspect becomes especially relevant in the context of the sanctions load. In view of the limited nature of Russian institutional investors and the decrease in the share of non-residents in the turnover on the Russian securities market, the emphasis is shifting to private investors. Professional intermediaries providing investors with the necessary services, investment products and infrastructure solutions are able to contribute to the sustainable presence of private investors in the market. The authors present a detailed analysis of the processes of development of private investment using the mechanisms of professional mediation in the securities market, identifying cause-and-effect relationships of the current dynamics for the period 2017–2021. The study made it possible to identify a number of factors that determine the presence and activity of private investors in the market.

Clustering of regions, not only by economic parameters, but also by tax parameters is a new direction of economic research. The purpose of this article is to group the regions of the Russian Federation according to the industry specifics of their tax revenues and identify common features for each of the established clusters. The industry specifics of the regions in terms of the parameter of tax revenues of budgets are investigated using cluster analysis using the ORANGE software product. The empirical basis of the study was the data of the Federal Tax Service on the structure of tax revenues of the consolidated budget of the regions by type of economic activity for 2017. This period is purely conditional and is used only for the purpose of testability of the method used to find the optimal number of clusters on the territory of Russia for further research. The conducted research has shown that the regions of the Russian Federation have specifics in accordance with the sectoral structure of tax revenues. According to the results of the analysis, nine clusters were identified. Of the nine clusters, three have industry — specific types of economic activity — manufacturing and mining. In two clusters, tax revenue indicators are above average for almost most types of economic activity. Four clusters demonstrate high tax revenues for such types of economic activities as transportation and storage, public administration, education, healthcare, construction, as well as manufacturing, and mining. The data obtained make it possible to develop a «personalized» tax policy of each entity.

Authors: Suranova Oksana
Published: December 2023

he article analyzes the measures of state financial support of accommodation facilities in the context of the implementation of the national project «Tourism and the hospitality industry». It is noted that the lack of accommodation facilities is one of the constraining factors for the development of domestic and inbound tourism in the Russian Federation. The solution of this problem is carried out with the involvement of state funding. The article reveals the directions (priority types of accommodation facilities created with the participation of state financing) and forms of financial support (investments, subsidizing the interest rate for the construction (reconstruction) of hotels and grant support for public, entrepreneurial and regional initiatives aimed at the development of tourism, state guarantees). The coordinator of financial support is Federal Agency for Tourism of the Russian Federation (Rostourism). The implementation of these measures will ensure an increase in the number of high-quality year-round hotels in all regions of the Russian Federation, which will contribute to increasing competition in the market, and will have a positive impact on the price-quality ratio of recreation sector in the country.
Modeling the Size of Tax Revenues by Probabilistic Laws
Authors: Leonova Olga
Published: December 2023

In order to obtain objective data based on the results of the study, the planned indicators of the budgets of all subjects of the Russian Federation for the upcoming financial year are not taken as a basis, but the actual parameters obtained for the execution of budgets for the past financial year. Practice shows that every year almost all budgets of subjects and the consolidated budget of the state receive significantly more tax funds than was provided for when adopting budgets for the coming year. It would be erroneous to attribute this excess of actual tax revenues over planned ones due to the more efficient operation of the economic sector. The subjective factor plays an important role here. Local tax and financial authorities, the Federal Tax Service and the Ministry of Finance of the Russian Federation, which are responsible for developing draft budgets for the upcoming financial period and ensuring their execution, sometimes underestimate the actual possible amount of tax revenues for pragmatic reasons. Based on the above, the analysis is based on statistical data on the execution of budgets of the constituent entities of the federation for the past year.
This research is devoted to modeling the size of tax revenues to the consolidated budget of the Russian Federation. In the article, the reporting data on the size of tax revenues are approximated by the following probabilistic laws: exponential distribution, Pareto distribution, gamma distribution (Erlanger distribution), and lognormal distribution. For each class of distributions, the problem of estimating unknown parameters using maximum likelihood and moments methods is solved. As a result of the study, it was found that the distribution of tax revenues is best described by the Pareto law and the log-normal mode.

Published: December 2023

El problema y debate sobre la disyunción de la filosofía y la clínica psicoanalítica es un fenómeno que ha traído diversas discusiones desde ambas aristas teóricas. En el presente documento se abordan algunas de las contribuciones más recientes al debate filosófico en implicancia con las modificaciones de la clínica psicoanalítica actual. Nuestro objetivo fue mediante un análisis documental con miramiento teóricocrítico contribuir al esclarecimiento de las herramientas fundamentales que la filosofía entrega a la modificación de la teoría y práctica psicoanalítica. Para tal efecto, hemos trazado un recorrido histórico general a las modificaciones y argumentos que a lo largo de la historia del psicoanálisis hanido emergiendo. Finalmente, exponemos algunos de los debates y tesis pendientes de continuar explorando, en miras de la mixtura de los saberes y en beneficio de las reflexiones y análisis enfocados en la condición humana, cuestiones que tanto la filosofía como el psicoanálisis tienen como ejes centrales.

In an era of urbanization, urban livability is a critical concern. This study explores the relationship between administrative capacity and urban livability in Türkiye's 81 provinces. Recent global attention to administrative capacity highlights its role in governance and societal progress. The research emphasizes the importance of enhancing administrative capacity for positive outcomes, including improved urban livability, and examines the impact of provincial administrative capacity on urban livability geographically. A robust administrative capacity is crucial for effective public institutions, from local to international levels. Recent research shows it fosters better institution performance, economic growth, democracy, policy effectiveness, conflict prevention, counterterrorism, and local democracy. Among such contributions administrative capacity is also key to a city's success, attracting residents and businesses, enhancing urban livability. In order to reveal such dynamic, the study covers all 81 Turkish provinces, testing geographic variations in the impact of administrative capacity on livability. It uses provincial administrative capacity and Forbes Magazine's livability index in global and geographical regression models. The results confirm a strong relationship between provincial administrative capacity and urban livability. Geographically, this impact varies across regions. In conclusion, the research reveals the importance of administrative capacity in shaping urban livability. Policymakers and urban planners should focus on enhancing administrative competence to improve residents' quality of life, fostering informed decision-making and policy formulation for livable cities.
Nova interpretacija sadržaja slike Lazzara Bastianija u samostanu sv. Frane u Zadru
Authors: Jurković Ivan , Prijatelj Pavičić Ivana
Published: December 2023

The sacristy of the monastic Church of St. Francis (Sveti Frane) in Zadar, held by the Franciscan Province of Saint Jerome, holds a painting by Lazzaro Bastiani, a Venetian painter of the early Renaissance. The painting is venerated as a depiction of the Virgin of Mercy (Ara Coeli). The upper section of the painting features the Blessed Virgin Mary and the infant Jesus. The Virgin is shown sitting in a mandorla made of angels with a crescent beneath her feet. God the Father is placing a crown on her head. Two angels are holding the ends of her outspread cloak, in front of which are saints: the men on the right and the women on the left. A church is depicted against the backdrop of a hilly landscape. It is positioned on a mound, with a railing ending in a staircase leading to it. The lower section of the painting features three groups, all genuflecting: men to the left, children in the middle, and women to the right. The group of men is dominated by the figure of Pope Sixtus IV (1471‒1484). Even after 175 years of research, the following questions remain contested: • the dating of the painting and the date of its arrival in Zadar • the identification of the patrons and the interpretation of the painting’s symbolism • the identification of the shrines depicted in the painting, and, finally • the identification of the historical figures featured. The aim of the authors is to try to elucidate, at least in part, the theological and historical context of the painting’s production, and to identify the historical figures and the shrine of the Blessed Virgin Mary depicted therein.
