The resource theory of nonclassicality of channel assemblages
Authors: Zjawin Beata , Schmid David , Hoban Matty J. , Sainz Ana Belén
Published: October 2023

When two parties, Alice and Bob, share correlated quantum systems and Alice performs local measurements, Alice's updated description of Bob's state can provide evidence of nonclassical correlations. This simple scenario, famously introduced by Einstein, Podolsky and Rosen (EPR), can be modified by allowing Bob to also have a classical or quantum system as an input. In this case, Alice updates her knowledge of the channel (rather than of a state) in Bob's lab. In this paper, we provide a unified framework for studying the nonclassicality of various such generalizations of the EPR scenario. We do so using a resource theory wherein the free operations are local operations and shared randomness (LOSR). We derive a semidefinite program for studying the pre-order of EPR resources and discover possible conversions between the latter. Moreover, we study conversions between post-quantum resources both analytically and numerically.
Modern Trends in Research Assessment: A Case of the Netherlands
Authors: Kochetkov D. M.
Published: October 2023

After the departure of commercial scientific information databases such as Scopus and Web of Science from Russia, the problem of building a new system for research assessment is more relevant than ever. At the same time, the new system does not have to copy the previous one with other data sources. The purpose of the article is to analyze global trends in the field of research evaluation. The authors have examined key supranational documents and practices in introducing a responsible approach to research assessment in the Netherlands. All the reviewed sources agree on one point: research activities should not be assessed based solely on quantitative indicators, especially on the basis of surrogate measures of quality such as impact factor. In the Netherlands, all the key stakeholders in the research sphere adhere to responsible research evaluation. An important role is played by the concept of valorization, which involves the use of scientific research results in the economy and for the benefit of society as a whole. The experience of the Netherlands can be used in Russia to build an advanced system for assessing research activities, which will contribute to achieving the development goals of our country and the implementation of priorities in the scientific, technical, and socio-economic spheres.

“Enlightenment” or “Enrichment”: About the Values and State of Russian Post-reform Society in A. I. Ertel’s Series “Notes of Stepnyak”
Authors:   Kostroma State University, Smirnova Irina Yu.
Published: October 2023

The article examines the ideological and artistic originality of the book of essays by A. I. Ertel “Notes of Stepnyak.” It manifests itself in the fundamentals of organizing the integrity of the entire collection, the writer’s worldview, and the relationship between the position of the author and the narrator in the book. The work emphasizes that Ertel was often credited with extreme populist views, but the writer saw his task not only in helping the people, but in the improvement and transformation of the entire Russian society, Russian life, which was confidently and quickly losing its moral core and high moral standards. The author of the article comprehends the main motifs of the book of essays and the principles of organizing the system of characters in it. Ertel’s letters to his contemporaries, his reasoning allow to describe and characterize writer’s attitude towards the Russian people and the main problems of Russian post-reform life.
“They Divided the Estate During the War”: L. N. Tolstoy’s Traditions in the Estate Text of the 20th Century
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Knorre Elena Yu.
Published: October 2023

The article is the first to reconstruct the estate theme in L. N. Tolstoy’s works in its intersection with the war theme. It turns out that the estate in Tolstoy’s works dedicated to war and revolutionary struggle plays a plotforming role. Using the examples of the stories “Caucasian Prisoner,” “Divine and Human,” the epic novel “War and Peace,” the author of the article traces the motif of the prodigal son’s return to his father’s house, his main phases of “departure” (“isolation”), “test” and “return” (“gaining new connections with the world”). War in this plot scheme appears as a limenal space of testing, the initiation of the soul on the path of returning to its true home. Summing up the results, it can be concluded that Tolstoy’s images of an ideal estate and house are opposed to war and are associated with biblical motifs of the Garden of Eden, a vineyard, symbolizing the “kingdom of God.” Tolstoy’s paradigm of the perception of the ideal estate as an image of righteous management and peacemaking, pacification of passions in serving God and people, becomes decisive in the depiction of the estate during the war in the literature of the 20th century.
M. I. Pushchin and His Autobiographical Memoirs
Authors:   St. Petersburg Institute of History of the Russian Academy of Sciences, Ilyin Pavel V.
Published: October 2023

The article examines the autobiographical notes of Mikhail Ivanovich Pushchin (1800–1869), the younger brother of the “first” and “priceless” friend of A. S. Pushkin, the Decembrist I. I. Pushchin. M. I. Pushchin was also one of the participants in the Decembrist movement and left a significant memoir legacy. The notes of M. I. Pushchin are in demand in Pushkin and Decembrist studies, but still do not have a complete scientific publication. They are of significant interest as a retrospective document describing the life of the era and a number of events of historical significance in the first half of the 19th century, and as memoirs written by an outstanding author — a guards and then an army engineer, a participant in the events of 1825 and military operations in the Caucasus, friend and acquaintance of many historical figures. The article characterizes the significance of M. I. Pushchin’s notes as a historical source, presents the first results of studying its manuscript that have come down to us, preserved among the Pushchin family papers, dates the available two editions of the notes, based on a comparison of the manuscript with the published text of the notes, and makes attempt was made to reconstruct the history of creation memorial monument.
Review of Tolstoy’s Mother M. N. Tolstaya Collection in the Manuscript Department of the National Library of Russia
Authors:   L. N. Tolstoy Museum-estate “Yasnaya Polyana”, Belousova Elena V.
Published: October 2023

The article presents an analysis of M. N. Tolstaya collection, kept since 1903 in the Manuscript Department of the National Library of Russia. It consists of 85 manuscripts with a common volume of 4027 sheets. In the 1810s–1820s Tolstaya translated from French into Russian the treatise “Le combat spiritual,” which was a translation of the medieval work of L. Skuupli “Il combattimento spiritual.” She titled her manuscript “Spiritual Combat.” She did not know the Russian text of Skupoli’s work, translated by I. S. Andreevsky in 1787, since it was forbidden to be printed. The article compares some fragments of the “Spiritual Battle” with the “Invisible Warfare” of St. Theophan the Recluse — the famous Russian translation of “Il combattimento spiritual.” For the purpose of religious enlightenment of the Yasnaya Polyana peasants in the 1820s Tolstaya writes “Instruction on the Christian Law, Selected from the Poor’s Store” — an independent work in the catechism genre. It is not known whether she knew the Catechism of Metropolitan Filaret, however, the general structure of these works has much in common. Tolstoy’s activity as a spiritual writer was caused by the desire to improve in the knowledge of God and to serve others.
Raisky and Paradise in The Precipice by I. A. Goncharov
Authors:   Pererva Theological Seminary, Melnik Vladimir I.
Published: October 2023

The article presents the novel The Precipice as the final part of the novel trilogy by I. A. Goncharov (by analogy with the canticle “Paradise” in the composition of the “Divine Comedy” by A. Dante). So Raisky appears as the central (not declaratively, but essentially) character of the novel, crowning Goncharov’s ideas of a “serious human figure” and an “idealist character.” The article examines the image of Raisky in its evolutionary development, and designates the vector of his spiritual movement as an experience of falling, repentance and resurrection. The image of the ascetic artist Kirilov clearly manifests Goncharov’s ideas about the purpose of art, about the indecomposable unity of art and religion. It turns out that the spiritual evolution of Raisky — from the “Petersburg” part of the novel to the “Malinovskaya” and to the finale — takes place under the sign of Kirilov’s ideological and aesthetic attitudes, despite the fact that they do not coincide with installations of both Raisky and Goncharov himself. For the first time, the article shows the character of the plot, which is particular for the general meaning of the novel, connected with the spiritual duel of Vera and Mark Volokhov, since all the main meanings of the work, including biographical ones, converge in the figure of Raisky.
Simulation of the influence of STATCOM on power system losses
Authors: Sosapanta Salas Joseph , Macías Gómez Miyerladis
Published: October 2023

The supply of growing electricity demand is possible through continuous technological advances and the expansion of national and international electrical systems. This scenario could introduce voltage drops and consequent changes in the reactive power flow throughout the electrical network. In order to control these problems, various strategies have been developed as a solution to improve the transport and distribution of electrical energy. One of them is the Flexible Alternating Current Transmission System (FACTS), and more specifically the STATic synchronous COMpensator (STATCOM). This paper investigates the influence and effectiveness of STATCOM to mitigate the losses in the transmission lines and its impacts on bus voltage drops. The simulations are performed using the software DIgSILENT PowerFactory and the results showed that STATCOM reduces the power system losses in an interval of 23.86% until 32.86%, and in addition, the STATCOM decreases the annual energy cost by 7.82% in the implemented test case.
Automatic voltage stabilization system for substation using deep learning
Authors: Moon Jiyong , Son Minyeong , Oh Byeongchan , Jin Jeongpil , Shin Younsoon
Published: October 2023

The operating voltage in the substation must be maintained at its rated voltage within the specified standard because a voltage outside the specified range may cause a malfunction of the power facility and interfere with the stable power supply. Therefore, the voltage regulation process to maintain the rated voltage of the substation is essential for the stability of the power system. However, the voltage regulation process is currently performed manually by resident staff. Voltage regulation based on human judgment increases the uncertainty of voltage stabilization and makes efficient operation in consideration of the economic feasibility of power facilities difficult. Therefore, this paper proposes an automatic voltage stabilization system that can automatically perform voltage regulation. Instead of predicting the electrical load or overvoltage conditions studied so far, we focus on more direct, scalable input capacity prediction for an automatic voltage stabilization system. First, the proposed system predicts the input capacity required for a given situation through a trained stacked LSTM model. Second, an optimal regulation plan is derived through an optimization process that considers the economic feasibility of power facility operation. Additionally, the development of the user interface makes it possible to visualize the operation of algorithms and effectively communicate the models? predictions to the user. Experimental results based on real substation data show that the proposed system can effectively automate the voltage regulation process.

Published: October 2023

Personalized training systems and augmented reality are two of the most promising educational technologies since they could enhance engineering students? spatial ability. Prior research has examined the benefits of the integration of augmented reality in increasing students? motivation and enhancing their spatial skills. However, based on the review of the literature, current training systems do not provide adaptivity to students? individual needs. In view of the above, this paper presents a novel adaptive augmented reality training system, which teaches the knowledge domain of technical drawing. The novelty of the proposed system is that it proposes using fuzzy sets to represent the students? knowledge levels more accurately in the adaptive augmented reality training system. The system determines the amount and the level of difficulty of the learning activities delivered to the students, based on their progress. The main contribution of the system is that it is student-centered, providing the students with an adaptive training experience. The evaluation of the system took place during the 2021-22 and 2022-23 winter semesters, and the results are very promising.
EMOTIONAL BURNOUT OF RESIDENTS STUDYING AT A MEDICAL UNIVERSITY AND DIRECTIONS OF ITS PSYCHOLOGICAL CORRECTION
Authors:   Ryazan State Medical University, Yakovlev V. V.
Published: October 2023

The article is devoted to the problem of emotional burnout of doctors studying in residency at a medical university. In a preliminary interview, professional, social, and personal factors were identified that contribute to the formation of a burnout syndrome. The set of methods of the main empirical study included Maslach–Jackson burnout questionnaires, Thomas–Kilman style of conflict behavior, Hall's emotional intelligence, Lazarus–Folkman coping test, methods for diagnosing the professional communicative competence of doctor Yakovleva and style self-regulation of Morasanova's behavior. It was revealed that certain symptoms of burnout are typical for 31% of residents who participated in the study. The results of the correlation analysis show numerous connections between burnout syndrome indicators both with personality traits that contribute to the formation of typical symptoms (tendency to confrontation, avoidance and distancing in social contacts, striving for excessive independence with a lack of professional experience), and determining personal resistance to negative professional factors (the desire for cooperation, compromise and, in general, the formation of adequate communication skills in interaction with patients and colleagues, rational coping strategies, productive components of self-regulation). The targets of psychological prevention and correction of professional burnout among residents were identified. Based on the results of the study, program, that includes information-diagnostic, consulting-correctional and educational-developing directions, has been developed and introduced into the educational process at a medical university.

Authors:   Togliatti State University, Chapala T. V. , Ilich M. ,   Togliatti State University
Published: October 2023

The topicality of the research is confirmed by data showing a high incidence of gastrointestinal (GI) diseases in the Russian Federation in comparison with other European countries. Patients with gastrointestinal (GI) disease have been reported by clinicians to be emotionally unstable during disease exacerbations. This article presents a study of the relationship between psycho-emotional states and individual typological characteristics in women of different ages with GI disease. Levels of indicators of anxiety and depression in women with GI disease were investigated. The purpose of the study was to determine the peculiarities of anxiety and depression levels in women with GI diseases in relation to temperament type and age; using correlation analysis, to determine the relationship between neuroticism and emotional state, temperament type, and levels of anxiety and depression in the study participants. The study involved 28 women with diseases of the gastrointestinal tract, aged 42 to 72 years. The Eysenck Personality Inventory (EPI), the Spielberger State-Trait Anxiety Inventory (STAI) and the Beck Depression Inventory (BDI) were used in the research. From the results obtained, it can be concluded that most women with gastrointestinal disorders have an introverted personality type with high neuroticism. It was found that women with a melancholic temperament type had the highest scores on the Personality Anxiety Scale and on the Cognitive-Affective Manifestations of Depression subscale and the General Depression Scale, whereas women with a sanguine temperament type had the lowest scores for all indicators. The results of the study may be of practical importance in providing psychological support to women with gastrointestinal diseases in hospital, taking into account their individual typological characteristics and emotional state.

The frequency of depressive disorders in the modern world is increasing. These disorders have a range of symptoms that affect quality of life. Athletes, because of the nature of their activity, are also subject to these symptoms, as they have to expend a lot of energy, both physically and psychologically. The objective of the study was to identify the specific factors associated with depressive symptoms that are characteristic of athletes and to explore their relation to the level of depression. A total of 46 athletes aged from 18 to 54 years (Mage = 24, SDage = 6.49) of different sports participated in the study. Several methods were chosen as diagnostic tools to study the level of depression, the level of perceived stress, emotional burnout and perfectionism in athletes. It was shown that the higher the level of emotional burnout, stress, perfectionism and decrease in performance were, the higher the level of depressive symptoms was. The conducted research confirmed the importance of studying the factors of depression symptoms and revealed the necessity of developing ways to control these factors in athletes in order to avoid increasing depressive tendencies.
PECULIARITIES OF LIFE ORIENTATIONS AND ATTITUDES TO DIFFERENT SIDES OF REALITY IN PEOPLE PRONE TO AUTO-DESTRUCTIVE BEHAVIOR
Authors:   Tyumen State University, Moreva G. I. , Volodina K. A. ,   Tyumen State University
Published: October 2023

The article presents the results of the research studying the attitude system in people prone to self-destructive behavior (alcohol addiction, extreme sports). In the last decade, there has been an increase in forms of self-destructive behavior, which causes great interest to the chosen research area. The study sample consisted of 90 participants: 30 men dependent on alcohol; 30 men, fans of extreme sports; 30 men (control group) who do not drink alcohol and do not engage in dangerous sports. The research tools used were the test of life-meaning orientations by D. A. Leontyev, a technique of unfinished sentences aimed at identifying ideas about oneself, about attitudes to various aspects of reality (primarily to life and death). The research revealed differences among the study groups in terms of meaningfulness, direction, and controllability of life. Representatives with alcohol dependence demonstrated reduced values in many parameters of attitude towards life and towards themselves, and did not demonstrate interest in finding the meaning of life. It is typical for fans of extreme sports to take an active life position, make plans for the future, fill their activities with meaning and be completely satisfied with their lives.

Published: October 2023

The Inflation Reduction Act of 2022 (IRA) represents the largest climate policy action ever undertaken in the United States. Its legislative path was marked by two abrupt shifts as the likelihood of climate policy action fell to near zero and then rose to near certainty. We investigate equity price reactions to these two events, which represent major realizations of climate policy transition risk. Our results highlight the heterogeneous nature of climate policy risk exposure. We find sizable reactions that differ by industry as well as across firm-level measures of greenness such as environmental scores and emission intensities. While the financial market response to the IRA was economically significant, it did not lead to instability financial stress, suggesting that transition risks posed by climate policies even as ambitious as the IRA may be manageable.

The main aim of this study is to evaluate the usefulness of Institute of Geodesy at Graz University of Technology (ITSG) daily gravity field models in the determination of hydrological angular momentum (HAM) at nonseasonal time scales. We compared the equatorial components (χ1 and χ2) of HAM calculated with the ITSG daily gravity field models (ITSG-Gravity Recovery and Climate Experiment [ITSG-GRACE] 2016 and ITSG-GRACE 2018) with HAM and sea-level angular momentum (SLAM) from hydrological land surface discharge model (LSDM) and the hydrological signal in the polar motion excitation (known as geodetic residuals [GAO]). Data from ITSG have a daily temporal resolution and allow us to determine oscillations with higher frequencies than the more commonly used monthly data. We limited our study to the period between 2004 and 2011 because of the gaps in GRACE observations before and after this period. We evaluated HAM obtained from ITSG GRACE models in spectral and time domains and determined the amplitude spectra of the analyzed series in the spectral range from 2 to 120 days. Our analyses confirm the existence of a sub-monthly signal in the HAM series determined from ITSG daily data. We observed a similar signal in LSDM-based HAM, but with notably weaker amplitudes. We also observed common peaks around 14 days in the amplitude spectra for the GAO- and ITSG-based series, which may be related to the Earth’s tides. ITSG daily gravity field models can be useful to determine the equatorial components of HAM at nonseasonal time scales.
Neural network modelling of non-prosperity of Slovak companies
Authors: Durica Marek , Mazanec Jaroslav , Frnda Jaroslav
Published: October 2023

Early identification of potential financial problems is among important companies’ risk management tasks. This paper aims to propose individual and ensemble models based on various types of neural networks. The created models are evaluated based on several quantitative metrics, and the best-proposed models predict the impending financial problems of Slovak companies a year in advance. The precise analysis and cleaning of real data from the financial statements of real Slovak companies result in a data set consisting of the values of nine potential predictors of almost 19 thousand companies. Individual and ensemble models based on MLP and RBF-type neural networks and the Kohonen map are created on the training sample. On the other hand, several metrics quantify the predictive ability of the created models on the test sample. Ensemble models achieved better predictive ability compared to individual models. MLP networks achieved the highest overall accuracy of almost 89 %. However, the non-prosperity of Slovak companies was best identified by RBF networks created by the boosting and bagging technique. The sensitivity of these models is about 87 %. The study found that models based on neural networks can be successfully designed and used to predict financial distress in the Slovak economy.
Multi-skilled workforce scheduling with training and welfare considerations
Authors: Peña Diana A. , Osorio Andrés F. , Orejuela Juan P. , Idarraga Juan C.
Published: October 2023

Flexibility in workforce scheduling in services is necessary to reduce the impact of demand uncertainty, absenteeism, and desertion while maintaining high service levels. This paper studies the workforce scheduling problem, including multiple skill accumulation, training, and welfare, as well as flexibility for employees and the company. All these elements are modelled and included in a mixed-integer linear programming (MILP) model that maximises their accumulated skill level. A real case study based on the scheduling of lab assistants to laboratory practices at a university in Colombia is used to generate numerical experiments. Different experiments were conducted, and the results show that the level of skill achieved is highly sensitive to the number of assistants and the number of allocations. The experiments also showed that, while keeping the same number of lab assistants, it is possible to include flexibility and welfare constraints. Finally, the proposed model can generate schedules that achieve high levels of skills and meet the different constraints of the model, including balance, accumulation, demand and welfare.
Industry 4.0 technologies and managers’ decision-making across value chain. Evidence from the manufacturing industry
Authors: Młody Michał , Ratajczak-Mrozek Milena , Sajdak Maja
Published: October 2023

The paper aims to identify how Industry 4.0 technologies affect the quality and speed of the managers’ decision-making process across the different stages of the value chain, based on the example of the manufacturing sector. The paper adopts qualitative research, based on nine in-depth interviews with key informants, to capture senior executives’ experiences with implementing Industry 4.0 technologies in their organisations. The research is focused on three manufacturing industries: the automotive, food and furniture industries. The research shows that depending on the stage of the value chain, different Industry 4.0 technologies are more suitable for the support of managers’ decisions. Various Industry 4.0 technologies support decision-making at different stages of the manufacturing value chain. In the Design stage, 3D printing and scanning technologies play a crucial role. In the case of Inbound Logistics, robotisation, automation, Big Data analysis, and Business Intelligence are most useful. During the Manufacturing stage, robotisation, automation, 3D printing, scanning, Business Intelligence, cloud computing, and machine-to-machine (M2M) integration enable quick decision-making and speed up production. Sensors and the Internet of Things (IoT) optimise distribution in the Outbound Logistics stage. And finally, Business Intelligence supports decisions within the Sales and Marketing stage. It is also the most versatile technology among all particular stages. The paper provides empirical evidence on the Industry 4.0 technology support in decision-making at different stages of the manufacturing value chain, which leads to more effective value chain management, ensuring faster and more accurate decisions at each value-chain stage. When using properly selected Industry 4.0 technologies, managers can optimise their production processes, reduce costs, avoid errors and improve customer satisfaction. Simultaneously, Industry 4.0 technologies facilitate predictive analytics to forecast and anticipate future demand, quality issues, and potential risks. This knowledge allows organisations to make better decisions and take proactive actions to prevent problems.

The factors influencing consumer purchase decisions in electronic commerce platforms and the interrelationships of each element are prevalent in the domain literature. However, a comprehensive analysis of the complex interrelationships among the success factors remains unexplored, especially in a social commerce context. To address the gap, this work evaluates the relationship structure and determines the critical factors using interpretive structural modelling (ISM). On the other hand, the Matrice d’Impacts Croisés Multiplication Appliquée á un Classement (MICMAC) is introduced to analyse the interaction of the factors and recognise the most relevant among them. In demonstrating the ISM-MICMAC analysis, this work performed a case study evaluating 13 factors of social commerce success for food products derived from a previous study. The findings of this work suggest that timeliness, data privacy policy, and Internet connectivity drive most other factors. Thus, focusing the resources on augmenting these factors consequently improves other factors. These findings suggest that sellers must streamline their overall service chain to maintain timeliness in their transactions, safeguard consumers’ data privacy, and uphold consumer communication efficiency to maximise Internet connectivity. These insights provide useful information to help decision-makers in the food industry allocate resources and encourage more consumers for social commerce. Several managerial insights were discussed.

Bitcoin ¿una nueva alternativa de generar rentabilidad para los inversores?
Authors: Armella Garzon Carla Lorena , Retamozo Gareca Ana María , Cardozo Romero Rodrigo
Published: October 2023

Bitcoin es el ejemplo más emblemático de los beneficios que trajo consigo la innovación financiera; su aceptación y popularidad se deben a su capitalización. Sin embargo, hay quienes relacionan a Bitcoin con actividades delictivas que desencadenan en robos. En este sentido, el objetivo del presente estudio fue analizar la criptografía de la moneda virtual Bitcoin para determinar el riesgo de vulnerabilidad informática en la inversión. Obteniéndose que para vulnerar informáticamente la red se requiere que el 51% de toda la cadena de bloques sea reescrita, escenario imposible gracias a que la criptografía basada en la tecnología Blockchain hace que las transacciones con Bitcoin sean computacionalmente irreversibles. Finalmente, se prueba que la intimidación, fraudes y estafas son causantes de rechazo hacía Bitcoin, mas, el riesgo de ser víctima de este tipo de actividades delictivas en la inversión puede ser minimizado a través de la educación.
Análisis comparativo cualitativo de los factores de éxito de los planes de ordenamiento social de la propiedad rural en Colombia (2018-2021)
Authors: Rodríguez Moreno Ana Catalina , Hernández Alejandro , Martínez Cortés Luis Francisco
Published: October 2023

Producto de la firma de los acuerdos de paz en 2016 y el punto uno sobre Reforma Rural Integral, la institucionalidad agraria en Colombia asumió la tarea de implementar la política de Ordenamiento Social de la Propiedad Rural enfocada en extender a la población rural los mecanismos de legalización ofertados por el Estado en materia de acceso a la tierra y formalización de la propiedad rural. Frente al desarrollo de esta tarea, para el periodo 2018-2021, los autores presentan los principales aspectos de un análisis comparativo cualitativo (QCA, por sus siglas en inglés) sobre la formulación e implementación de los Planes de Ordenamiento Social de la Propiedad Rural, en el marco de nueve convenios interinstitucionales celebrados entre la Agencia Nacional de Tierras y otros socios formuladores e implementadores. El principal objetivo del estudio es analizar los factores condicionantes del éxito de la formulación e implementación de dichos POSPR, a la luz de lo que se conoce como la ‘ruta metodológica’. Específicamente, el estudio identifica y analiza sistemáticamente las principales variables involucradas en la relación entre objetivos trazados y resultados obtenidos desde un plan de acción, las cuales son analizadas como configuraciones de carácter plausiblemente causal. Para ello, se acude a técnicas mixtas de análisis y los hallazgos remiten a conclusiones sobre nexos (causales) entre las variables identificadas, mejorando la comprensión contextual de los Planes. Además de utilizar técnicas de análisis novedosas, el estudio contribuye a los ejercicios que buscan oportunidades para un mayor desarrollo de la ruta metodológica en Colombia.

Escarabajos degradadores de la madera (Coleoptera: Passalidae) de la isla Gorgona, Cauca, Colombia.
Authors: Pardo Locarno Luis Carlos , Editorial Asistente
Published: October 2023

Por tratarse de la única formación insular, selvática, del Chocó biogeográfico, en el pacífico colombiano, los atributos biofísicos y naturaleza del Parque Nacional Natural Gorgona (PNNG), Cauca, han despertado mucho interés en los últimos 20 años conducentes a múltiples estudios de su fauna, en especial de insectos. Sin embargo, llama la atención la ausencia de estudios sobre insectos degradadores y ninguna publicación sobre los escarabajos de la madera (Coleoptera: Passalidae) en esta localidad. Por lo tanto, este artículo registra las especies de estos escarabajos en el Parque Nacional Natural Isla Gorgona (PNNG). El muestreo se llevó a cabo del 28 al 31 de mayo de 1993 en los alrededores del campamento, en los senderos turísticos de la isla (Yundigua, La Chonta y Playa Palmeras). Se examinaron aproximadamente 17 troncos descompuestos, con diámetros desde 8-25 cm. Los  ejemplares fueron preservados en alcohol al 95%, posteriormente montados y depositados en la colección familia Pardo-Locarno (CFPL-COL, Palmira, Valle); parte del material fue comparado en el INECOL (Xalapa de Enríquez Veracruz, México) y en el Museo de Historia Natural (Paris, Francia); se registraron cuatro especies: Passalus emberaorum Jimenez-Ferbans et al. (2018) (n=18; 60%), Veturius sinuatocollis Kuwert (1890) (registro bibliográfico), Veturius aspina Kuwert 1898 (n=10; 33,33%) y Petrejoides caldasi Reyes-Castillo y Pardo-Locarno (1995) (n=2; 6,66%). P. emberaorum y Pe. caldasi se consideran nuevos registros para el PNNG. El artículo proporciona una clave taxonómica e ilustraciones de la especie. Además, enfatiza la necesidad de una mayor investigación sobre la estricta naturaleza saproxilófaga del grupo y su importancia en términos del valor de conservación de este ecosistema único de la selva insular.
ECONOMIC NATURE OF THE “BUBBLE” IN THE INTERNATIONAL REAL ESTATE MARKET

Published: October 2023

The article is aimed at studying the economic nature and origin of the real estate bubble, its financial and economic impact, and the relevant consequences and risks for international real estate markets. The article also notes that during the boom period, theincrease in supply is driven by the growth of demand for real estate from end users (the real sector of the economy), and during the bust period -by the growth of demand from investors. The oversupply in the market during the period of market saturation is largely due to the investment in real estate that preceded it during the boom. During this period, real estate is no longer seen as a real asset, but rather as a financial asset that generates income without regard to its connection to the real economy.This, together with rising household in-comes and increased mortgage lending, led to the emergence of real estate bubbles.A real estate bubble is defined as a sharp increase in prices and market turnover in the real estate market caused by a significant increase in demand (including speculative demand for the purpose of further sale). The factors contributing to the emergence of the real estate bubble have been identified as follows: sustained high rates of economic growth; high rates of growth of household incomes; increased availability of mortgage lending (lower requirements for borrowers); increased availability of construc-tion lending; and increased investment in real estate.

Целью данного исследования является оценка частоты артериальной гипертензии и некоторых факторов риска ее развития у коренного и пришлого населения Якутии. Проведено исследование работающего коренного и пришлого населения Анабарского и Алданского районов Якутии. Всего обследовано 395 человек, из них 216 человек коренной национальности, некоренной 179 человек. Выявлена высокая частота встречаемости абдоминального ожирения, характерна для некоренных мужчин и женщин обеих групп с наибольшей тенденцией у женщин коренной национальности. Выявлена высокая частота артериальной гипертензии 56,9% у коренного и 56,4% у некоренного населения. Исследование средних значений липидного спектра показало, что у некоренного населения средние концентрации ОХС, ЛПВП и ТГ значимо выше по сравнению с коренными жителями. Но средний показатель ХС ЛПНП превышал у коренного населения, наиболее характерно для женщин. Средние концентрации ТГ как у мужчин, так и у женщин достоверно превышали у некоренного населения. Выявлена сопряженность с САД ОХС, атерогенной его фракции и ТГ у коренных жителей, а у некоренных с ТГ и глюкозой крови. Проведенное исследование коренного и пришлого населения Якутии выявило ряд негативных моментов. Наблюдается увеличение распространения артериальной гипертензии, атеросклероза у коренного населения ввиду глобального изменения образа жизни, характера питания. Выявлена одинаковая частота встречаемости артериальной гипертензии у коренного и пришлого населения Якутии. Абдоминальное ожирение имели более половины респондентов, чаще у некоренных мужчин, у женщин без существенной разницы по этнической принадлежности. Нарушение липидного обмена сопряжено с артериальной гипертензией у коренных малочисленных народов, углеводного – у некоренного населения Якутии.
Languages in the Khanty-Mansiysk National Pedagogical College, 1950s
Authors: Kiselev Aleksandr G.
Published: October 2023

t. Using the example of the National Pedagogical College, the study shows a signifi - cant change in the language situation in Khanty-Mansi Okrug— one of the northern districts of the RSFSR in the fi rst half of the 1950s. Even before the “Big Oil” era, the established educational and other social practices strengthened the position of Russian, weakening the position of the native languages of the peoples of the North. Among the emerging national intelligentsia, a nihilistic attitude towards their native language developed.

We report piperazine-fused six-membered-cyclic dichalcogenides as rapid-response redox substrates that interface with thiol/disulfide redox biology. Combining the stability of 1,2-dithianes with unprecedentedly rapid kinetics of self-immolation after reduction, these motifs are uniquely high-performance reduction-responsive motifs for live cell probes. We develop scalable, diastereomerically pure, six-step synthetic routes with just one chromatographic purification to access four key cis- and trans-piperazine-fused cyclic disulfide and diselenide cores. Fluorogenic redox probes using the disulfide-piperazines are activated >100-fold faster than the previously known monoamines, allowing us to deconvolute the kinetics of the reduction and the cyclisation steps during activation. The cis- and trans-fused diastereomers have remarkably different reductant specificities: the cis disulfides are activated only by strong vicinal dithiol reductants, but the trans-fused disulfides are activated even by moderate concentrations of monothiols such as GSH. Thus, although both disulfides are substrates for redoxins, in cellular applications the cis-disulfide probes were found to selectively report on reductive activity of thioredoxins, while the trans-disulfides are more rapidly but more promiscuously reactive. Finally, we showcase efficient late-stage synthetic diversification of the piperazine-disulfides, promising their broad applicability as robust cleavable cores for redox probes and prodrugs in biology, for solid phase synthesis and purifications, and as stimulus-responsive linkers for bifunctional reagents and antibody-drug conjugates.
A STUDY ON SELECTION OF BALLAST WATER TREATMENT TECHNOLOGIES TO MEET BWM 2004 CONVENTION
Authors: Nguyen T. H , Le T. H , Dong T. M. H , Le V. V
Published: October 2023

Ballast water is essential for ship operation. However, it also carries potential risks of contamination and disease transmission. The Ballast Water Management Convention (BWMC) was introduced by the International Maritime Organization (IMO) to minimize the transfer of pathogenic microorganisms to ecologically sensitive marine areas, through ballast of ocean-going ships. Therefore, thorough research and analysis of ballast water treatment technologies are essential. This paper summarizes the existing technologies applied for ballast water treatment. These technologies can be port-based or ship-based, with the latter being easier to implement. Particular attention is given to onboard processing methods, which can be classified as physical separation, mechanical or chemical methods. This work describes recent ballast water treatment studies from the scientific and academic communities since the last IMO Convention in 2004, and the treatment methods that have been approved by the IMO substantially and ultimately. We have examined the various methods currently available in scientific means for ballast water treatment and we conclude that standardization of ballast water treatment still has to be done to ensure IMO Standards.
