Background: Age-related remodelling has the potential to affect the microvascular response to hyperemic stimuli. However, its precise effects on the vasodilatory response to adenosine and contrast medium, as well as its influence on fractional flow reserve (FFR) and contrast fractional flow reserve (cFFR), have not been previously investigated. We investigate the impact of age on these indices. Methods: We extrapolated data from the post-revascularization optimization and physiological evaluation of intermediate lesions using fractional flow reserve (PROPHET-FFR) and The Multi-center Evaluation of the Accuracy of the Contrast MEdium INduced Pd/Pa RaTiO in Predicting (MEMENTO) studies. Only lesions with a relevant vasodilatory response to adenosine and contrast medium were considered of interest. A total of 2080 patients, accounting for 2294 pressure recordings were available for analysis. The cohort was stratified into three age terciles. Age-dependent correlations with FFR, cFFR, distal pressure/aortic pressure (Pd/Pa) and instantaneous wave-free ratio (iFR) were calculated. The vasodilatory response was calculated in 1619 lesions (with both FFR and cFFR) as the difference between resting and hyperaemic pressure ratios and correlated with aging. The prevalence of FFR-cFFR discordance was assessed. Results: Age correlated positively to FFR (r = 0.062, p = 0.006), but not with cFFR (r = 0.024, p = 0.298), Pd/Pa (r = –0.015, p = 0.481) and iFR (r = –0.026, p = 0.648). The hyperemic response to adenosine (r = –0.102, p ≤ 0.0001) and to contrast medium (r = –0.076, p = 0.0023) showed a negative correlation with age. When adjusted for potential confounders, adenosine induced hyperaemia was negatively associated with age (p = 0.04 vs p = 0.08 for cFFR). Discordance decreased across age terciles (14.64% vs 12.72% vs 10.12%, p = 0.032). Conclusions: As compared to adenosine, contrast induced hyperaemia appeared to be less affected by age. cFFR may be considered a more stable and reproducible tool to assess epicardial stenosis in elderly patients.

Authors: Gonzalez-Garcia Mauricio , Conde-Camacho Rafael , Díaz Katherine , Rodríguez-Cortes Camilo , Rincon-Alvarez Emily
Published: July 2024

Background: Cardiopulmonary exercise testing (CPET) assesses exercise capacity and causes of exercise limitation in patients with pulmonary hypertension (PH). At altitude, changes occur in the ventilatory pattern and a decrease in arterial oxygen pressure in healthy; these changes are increased in patients with cardiopulmonary disease. Our objective was to compare the response to exercise and gas exchange between patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) residing at the altitude of Bogotá (2640 m). Methods: All patients performed an incremental CPET with measurement of oxygen consumption (VO2), dead space (VD/VT), ventilatory equivalents (VE/VCO2), and alveolar–arterial oxygen gradient (PA-aO2). X2 test and one-way analysis of variance were used for comparisons between PAH and CTEPH. Results: We included 53 patients, 29 with PAH, 24 with CTEPH, and 102 controls as a reference of the normal response to exercise at altitude. CTEPH patients had a higher New York Health Association (NYHA) functional class than PAH (p = 0.037). There were no differences between patients with PAH and CTEPH in hemodynamics and VO2% of predicted (67.8 ± 18.7 vs. 66.0 ± 19.8, p < 0.05), but those with CTEPH had higher dyspnea, VD/VT (0.36 ± 0.09 vs. 0.23 ± 0.9, p < 0.001), VE/VCO2 (45.8 ± 7.1 vs. 39.3 ± 5.6, p < 0.001), and PA-aO2 (19.9 ± 7.6 vs. 13.5 ± 7.6, p < 0.001) than PAH patients. Conclusions: At altitude, patients with PH present severe alterations in gas exchange during exercise. There were no differences in exercise capacity between PAH and CTEPH, but patients with CTEPH had more dyspnea and greater alterations in gas exchange during exercise. CPET made it possible to identify alterations related to the pathophysiology of CTEPH that could explain the functional class and dyspnea in these patients.

Published: July 2024

Happiness becomes a benchmark of how people assess their lives, not only in terms of economic but also social and cultural. This research analyzes how Balinese people perceive happiness in terms of social, economic, and artistic. Quantitative and qualitative approaches were combined in the study. Denpasar City was chosen as the research location considering that Denpasar City is the capital of Bali Province, which acts as the centre of government and economy but still has traditional cultural values that its people closely carry. Data collection using questionnaires was distributed to 100 respondents. Data was analyzed descriptively, and correlation analysis was used to see how much economic, social, and cultural influences on people's happiness in Denpasar City. Information from in-depth interviews was analyzed using word clouds to see how people perceive happiness. The results show that happiness is viewed in terms of economy, income, life, culture, and satisfaction. Both economic, cultural, and social are still variables that influence happiness. The interview results also show that compared to those with high incomes, people feel happier when they gather with family and the surrounding community while doing various religious activities closely related to Balinese culture.

Public-Private Partnership Model of Correctional Institution: A Comparison Study in Various Countries
Authors: Aisyah Sani Siti , Meliala Adrianus Eliasta , Sulhin Iqrak
Published: July 2024

This study highlights that Public-Private Partnership (PPP) in correctional institution is not only represented by privatization or private, but is represented by various patterns of private involvement in correctional institution PPP models. Through an exploratory approach in the literature, this study identifies four correctional institution PPP models based on the experience of various countries, namely the "privatization" model, the "hybrid management" model, the "service infrastructure" model, and the "contracting out certain limited functions" model. The characteristics of the four correctional institution PPP models are identified through their similarities and differences based on the scope of private involvement in correctional institution construction and operation. Only the "privatization" model allows private involvement in all aspects of correctional institution development and operation, while the other three PPP models allow private involvement in certain aspects while still positioning the government to control management and custody aspects. The emergence of the three correctional institution PPP models other than "privatization" is the result of the adaptation of the consideration and/or application of the "privatization" prison PPP model.

Published: July 2024

The increased risk of cardiovascular disease in people with spinal cord injuries motivates work to identify exercise options that improve health outcomes without causing risk of musculoskeletal injury. Handcycling is an exercise mode that may be beneficial for wheelchair users but further work is needed to establish appropriate guidelines and requires assessment of the external loads. The goal of this research was to predict the 6-degree-of-freedom external loads during handcycling from data similar to that which can be measured from inertial measurement units (segment accelerations and velocities) using machine learning. Five neural network models and two ensemble models were compared against a statistical model. A temporal convolutional network (TCN) yielded the best predictions. Predictions of forces and moments in-plane with the crank were the most accurate (r = 0.95 - 0.97). The TCN model could predict external loads during activities of different intensities, making it viable for different exercise protocols. The ability to predict the loads associated with forward propulsion using wearable-type data enables the development of informed exercise guidelines.
An International Study of Advocates’ Strategies & Needs
Authors: Faunalytics  , Stennett Jack
Published: July 2024

Animal advocacy organizations employ diverse strategies to support farmed animals that range from individual action all the way up to large-scale national interventions. This diversity in tactics creates a need for impact evaluation—while much of the advocacy research measures the effectiveness of various approaches or develops related theories of change, less attention has been paid to understanding why organizations prefer certain strategies, decide to adopt new ones, or stick to what they know. Using a survey of over 190 animal advocacy organizations in 84 countries and six small focus-group discussions, this study aims to understand the diverse approaches taken by farmed animal protection groups globally, focusing on how and why organizations choose to pursue these advocacy strategies.
Recognizing People’s Agency Amidst Disadvantage: How to Study Inequality Using a Holistic Approach that is Accurate and Non-Stigmatizing
Authors: Bauer Christina , Miller-Cotto Dana , Silverman David , Frankenhuis Willem
Published: July 2024

In understanding the psychology of social inequalities, research has often portrayed groups of individuals in disadvantaged positions as lacking in agency, skills, or motivation – portrayals that can stigmatize these groups. Countering this stigma, recent developments have been made in so-called ‘strength-based’ research to better understand and acknowledge the agency, skills, and motivation people in disadvantaged positions often show. Yet, this research is not focused on understanding how inequalities emerge. The present research explores ways to study inequalities without risking to stigmatize people. For example, how can we address disparities in certain motivational factors (e.g., belonging, or confidence) without stigmatizing groups as lacking motivation? And how can we study the way people experience disadvantage, without reducing them to the role of weak, passive victims? To answer such questions, we integrate traditional social-inequality research with recent advances in strength-based research in what we call a ‘holistic approach’ to studying inequality. At the core of this approach is a simultaneous recognition of context-level disadvantage (a focus of traditional inequality research) and individual-level agency (a focus of strength-based research). This approach allows for a broader – holistic – perspective on existing inequality-research, and points to underexplored research questions within social psychology (e.g., how do people actively respond to disadvantage?). After outlining this approach, we distill it into 10 practical guidelines and illustrate how to implement guidelines in an existing research agenda. In doing so, we hope to support authors, reviewers, editors, and other stakeholders aiming for an accurate and non-stigmatizing study of inequalities.
Development and application of a comprehensive glossary for the identification of statistical and methodological concepts in peer review reports
Authors: Buljan Ivan , Costa Daniel Garcia , Grimaldo Francisco , Klein Richard Anthony , Bakker Marjan , Marusic Ana
Published: July 2024

The assessment of problems identified by peer researchers during peer review is difficult because the content of these reports is typically confidential. The current study sought to construct and apply a glossary for the identification of methodological and statistical concepts mentioned in peer review reports. Three assessors created a list of 1,036 different terms in 19 categories. The glossary was tested on the confidential PEERE database, a sample of 496,928 peer review reports from various scientific disciplines. The most frequently mentioned terms were related to data presentation (found in 40.3 % of the reports) and parametric descriptive statistics (33.3 %). Review reports suggesting a rejection were more likely to mention methodological issues, whereas statistical issues were raised more frequently in review reports recommending revisions. Across disciplines, methodological issues were more frequently mentioned in social sciences (64.1 %), while health and medical sciences were more predictive for the identification of statistical issues (40.1 %). Female reviewers identified more statistical issues compared to male reviewers. These results indicate that the glossary could be used as an additional tool for the assessment of the content of peer review reports and for understanding what help authors may need in writing research articles.
The Benefit of Removing Information from Working Memory: Increasing Available Cognitive Resources or Reducing Interference?
Authors: Li Chenyu , Frischkorn Gidon T. , Dames Hannah , Oberauer Klaus
Published: July 2024

Removing information from working memory is thought to free up capacity and improve the retention of other information. However, whether this benefit arises from reducing interference or freeing up cognitive resources remains unclear. We examined this by comparing removal immediately following encoding an item, or delayed until after other items have been encoded. Interference theories predict that both types of removal should reduce interference and improve memory performance. In contrast, if removal frees up resources, the beneficial effect on memory should be larger the earlier it occurs. Experiment 1 showed that both immediate and delayed removal failed to reduce interference from the to-be-forgotten items but improved memory for item-location bindings of other items still maintained in working memory. In Experiment 2, removal only facilitated item-location bindings for items encoded afterward. These results suggest that removal frees up working memory capacity by increasing available resources rather than by reducing interference.
Preservice Teachers' Motivation is Associated with Changes in Classroom Motivation (Klassen, Wang, & Thompson-Lee)
Authors: Klassen Robert M. , Wang Hui , Thompson-Lee Sophie
Published: July 2024

Preservice teachers’ motivation fluctuates as experience is gained and feedback is received from influential sources. Previous studies have explored changes in preservice teacher motivation over time, but rarely as a function of performance on classroom simulation tasks. We explored how performance on a series of classroom simulation tasks was related to changes in preservice teachers’ self-efficacy, career intentions, and perceived fit with the profession. The level of performance on classroom simulation tasks significantly predicted changes in self-efficacy, career intentions, and person-vocation fit, even after controlling for baseline levels of the constructs, as well as gender and age. Change in outcome variables was progressively more pronounced after the second and the third classroom simulation session.
How Much Do Citizens Care About Ethnic Wealth Gaps? Inequality and Support for Financial Market Stabilization in Times of Crisis
Authors: Bremer Björn , Chwieroth Jeffrey , Walter Andrew
Published: July 2024

People value household wealth as a source of private insurance, investment, and social status, which is reflected in their policy preferences. These preferences encourage governments to stabilize financial markets and protect private wealth during major economic crises. However, such policies often exacerbate wealth inequality, including between dominant and subordinate ethnic groups. We explore how citizens evaluate this trade-off by using information treatment and conjoint survey experiments in Australia and the UK in the wake of the COVID crisis. We find that information on ethnic wealth disparities has little, if any, effect on financial stabilization policy preferences, whereas information on ethnicity-neutral wealth inequality reduces support for such stabilization. Additionally, the conjoint experiment reveals greater acceptance of targeted interventions that reduce general wealth disparities than of targeted interventions to alleviate ethnic inequality. Our findings reveal a critical political economy constraint on contemporary policy efforts to address enduring inequities in multiethnic societies.
Before NBER: Warren Nutter’s Soviet Research at the CIA
Authors: Kuehn Daniel
Published: July 2024

Warren Nutter’s work as director of the National Bureau of Economic Research’s (NBER’s) Soviet growth project is his best-known contribution to economics and public affairs. Many histories of Sovietology note the oddity of Nutter’s selection as project director, given his apparent lack of prior experience studying the Soviet Union. This paper provides new context for Nutter’s selection to lead the NBER effort. From 1951 to 1952 Nutter was the Acting Chief of the Economic Capabilities Branch of the CIA’s Office of Research and Reports (ORR), and Chairman of the Economic Analysis Subcommittee of the interagency Economic Intelligence Committee. In this capacity he managed at least three major research efforts, including an input-output analysis of the Soviet Union and contributions to two national intelligence estimates. Nutter may have been proposed as director of the NBER project by Robert Amory, the Deputy Director of Intelligence, in 1953. Nutter’s research for the CIA cultivated new analytic capacities for the agency and provided a foundation for his own work on the Soviet Union.
Effect the Magnetic Field on the Focus of Ion Beam from Plasma Source
Authors: Joudah Hussein Bushra
Published: July 2024

One of the main component transport systems is a solenoid magnet, so in this study, a computational study was carried out to calculate some parameters of a solenoidal magnet. The most efficient technique to describe and track the charged particle beam along any optical system (in this example, a plasma source and two drift space areas before and after the solenoid magnet) is by theoretical analysis utilizing matrix representation, which has been provided. The configuration of the ion optical system necessary to create the magnetic identification focus and defocus the ion beam to the target using Matlab computational tools determines many magnet design elements, including magnetic rigidity, magnification, and focusing strength factor. The results demonstrate that a solenoid magnet functions as a convergent lens but can, under some circumstances, transform into a divergent lens. Additionally, changes in the solenoid magnetic field (B) affect the focusing of the beam that passes through the system, as indicated by the magnification values.

Published: July 2024

In the realm of investment decisions, the influence of behavioral biases has emerged as a captivating area of exploration. This article embarks on a comprehensive journey through the landscape of behavioral biases in investment choices, delving into their profound impact on financial markets. Contrary to traditional finance theories assuming rationality, a multitude of empirical evidence attests to the pervasive effects of cognitive and emotional biases. Through an extensive literature review, this article elucidates the intricacies of key biases such as overconfidence, loss aversion, anchoring, confirmation bias, herding behavior, disposition effect, framing effects, and regret aversion. By examining the distinct ways these biases distort investors' judgment and decision-making processes, we unveil the often unexpected deviations from rationality. Each bias, rooted in human psychology, can lead to suboptimal investment behaviors, portfolio misalignments, and heightened market volatility. However, recognizing the impact of these biases provides opportunities for transformative insights. As investment professionals, policymakers, and individuals alike comprehend the subtle nuances of behavioral biases, tailored interventions, educational initiatives, and adaptive strategies can be devised to mitigate their adverse effects. This article not only synthesizes the prevailing research but also charts a course for future investigations. The implications of understanding and addressing behavioral biases extend beyond financial realms, offering a bridge between finance and psychology. As interdisciplinary collaboration gains momentum, pathways for future research become evident, beckoning scholars to delve deeper into the uncharted territories of human behavior and its intricate relationship with investment decisions. Through the exploration of these biases and their potential remedies, this article illuminates the evolving landscape of investment decision-making in a world where cognitive fallacies intersect with financial choicest.

Authors: Deryaev Annaguly
Published: July 2024

The relevance of the research is justified by the rapid development of the oil industry, which requires constant improvement of methods and equipment to increase extraction efficiency and reduce environmental impact. The aim of this study is to enhance the current engineering aspects of drilling in the Altyguyi field while considering increased productivity and reduced environmental impact. Among the methods used, it is necessary to mention the synthesis method, abstraction method, generalization method, induction method, deduction method, classification method, and others. This study examines the technological aspects of operating wells in the Altyguyi gas-condensate field. Extensive laboratory and industrial research on the properties and composition of oil, gas, and condensate was conducted to properly implement the dual completion technology for gas extraction from one formation and oil extraction from another formation in a single well. By implementing advanced drilling methods, including horizontal and multi-hole drilling, as well as using modern drilling fluids, it was possible to improve well productivity and reduce drilling time. As a result of technology optimization, the overall efficiency of the oil and gas extraction process in the field has been increased, confirming the significance of innovation implementation for improving results in the oil industry. These enhancements not only increased drilling safety and efficiency, but also reduced the negative impact on the environment, emphasizing the importance of integrating modern technologies with environmental considerations in the oil extraction process. This research makes a significant contribution to the development of more efficient and environmentally sustainable drilling methods in oil fields, contributing to increased oil extraction productivity and reduced environmental impact

Published: July 2024

The study aims to address the physical properties and chemical composition of ash and slag waste from a thermal power plant to determine the possibility of its reuse in the heat and power industry. This included classification and chemical analysis of ash and slag waste generated by the Bishkek thermal power plant to determine its composition. The received material samples were also subjected to laboratory tests to determine the particle size distribution and moisture content. Once the fractionation boundaries were established, a detailed study of the ash mass was carried out, including carbon distribution analysis and flotation experiments to determine effective methods of carbon recovery from ash and slag waste. The results confirmed the significant potential of ash and slag waste from the Bishkek coal-fired thermal power plant for reuse in the heat and power industry. Analysis of the chemical components revealed the content of unburned coal particles within 10-11%, and the content of water-soluble sulphur and sulphuric acid compounds ranged from 0.18% to 0.71%. Experimental data confirmed the importance of the fractionation of ash and slag by particle size, which makes it possible to further separate coal fractions with different physical properties. The fraction of less than 150 microns is characterised by a low carbon content (less than 2.5%), which makes it suitable for use in construction as a fine aggregate. However, the study noted that fractions larger than 150 microns, and especially those larger than 300 microns, are a valuable feedstock for the production of carbon concentrate with a carbon content of more than 75%, which opens up the prospects for its use in the production of water-coal fuel. Thus, the results of the study confirm the potential of ash and slag waste for reuse in the heat and power industry. This can help to reduce waste, reduce the negative impact on the environment, and create efficient and sustainable production processes in the heat and power industry

The purpose of this study was to adaptively optimise sensor networks using unmanned aerial vehicles to reduce information losses and ensure the minimum possible technical performance of information transmission channels in the face of a considerable number of architectural obstacles. In this study, experiments were conducted on data transmission via a wireless channel using Wi-Fi technology, where the access point was placed on an unmanned aerial vehicle. The study was conducted in complex architectural settings, using the 2.4 GHz and 5 GHz frequency bands to investigate the behaviour of radio channels and assess their effectiveness in real-world conditions. As a result of the study, a new method for estimating and optimising the energy parameters of radio channels was proposed, which accommodates the influence of a range of factors to improve the coverage efficiency of wireless sensor networks based on unmanned aerial vehicles. This method helped to partially solve the problem of information losses through adaptive optimisation of network coverage when influencing factors occur. The experimental models developed in this study allow estimating the signal distribution in space for sensor networks based on unmanned aerial vehicles, considering the influence of external factors, using fluctuation coefficients. The study also developed a mechanism for using a control device that allows measuring signal strength at any distance from the base station, providing flexibility and accuracy of assessment. The results showed a prominent level of measurement accuracy, with 95% reliability for an observation period of 20 seconds and an error of up to ±0.5 dBm. The total error of the methodology does not exceed 5%, which confirms the high reliability of the results and their compliance with real operating conditions. Thus, the findings of this study contribute to improving the efficiency and reliability of wireless sensor networks based on unmanned aerial vehicles, providing stable and high-quality connection in various operating conditions

This case report describes the presentation and management of a 71-year-old male patient with sudden onset of chest pain. Despite an initial diagnosis of acute myocardial infarction (AMI) and pre-treatment with clopidogrel, further evaluation revealed the patient to have acute aortic dissection. The patient's condition rapidly deteriorated and ultimately led to his death. This case highlights the importance of careful diagnostic consideration when presented with symptoms of chest pain, particularly in high-risk patients, and the potential consequences of routine pre-treatment with P2Y12 inhibitors in such cases.

Introducción : En las ciudades con gran contenido patrimonial y que alcanzaron un papel relevante en el mundo romano –como es el caso de Córdoba (Andalucía, España), capital de la Bética romana– tiene una especial relevancia el fenómeno de la reutilización de materiales de la Antigüedad –principalmente pétreos– en las diferentes edificaciones de épocas más recientes, así como en las calles. Este artículo pretende presentar una propuesta de creación de una herramienta web para la compilación de estos materiales ubicados en el viario de Córdoba, concretamente el espacio intramuros que ocupó la ciudad en el Alto Imperio. Metodología : La propuesta plantea una revisión bibliográfica de la materia, la aplicación de los principios de la prospección arqueológica al vario cordobés, la recogida de datos de las piezas y el volcán en una página web. Resultados: La recopilación de los restos presentes en el víario de Córdoba y la creación de una herramienta web con funcionalidad académica, patrimonial y turística. Discusión y conclusiones : Se presenta una propuesta de herramienta web con sus diferentes ventajas y aplicaciones, que podrá servir de referencia para otras ciudades y territorios con un pasado romano relevante.
ПРИНЦИПИ ОПЕРНОГО AESTHESIS’У ТА ІДЕЯ ОПЕРНОГО ГЕРОЯ
Authors: Wang Miao
Published: July 2024

Мета дослідження – встановити головні історичні та теоретичні передумови виявлення оперного aesthesis’у. Дана мета передбачає порівняння двох площин оперної поетики – фактично-історичної, що зумовлюється власними жанрово-композиційними умовами та потребами оперної творчості; концепційними музикознавчими, що засвідчують усталені оцінки оперного досвіду, також дозволяють виокремлювати явища оперного розуміння – та оперної інтерпретації: іманентного смислового контенту опери – та способів, форм його відтворення, задіяння та перебудови. Методологія роботи включає принципи історіографічного, текстологічного, жанрово-стильвого та семантичного вивчення музичного матеріалу. Узагальнюючим та інтегративним прстає естетичний підхід, який виявляє суттєві психологічні аспекти. Наукова новизна даної статті забезпечується розвитком поглибленого, водночас контекстуального естетичного підходу до оперної творчості, що відрізняється особливими ціннісними призначеннями та синтетичними художніми можливостями. Запроваджене поняття естезису (aesthesis’у) дозволяє поглянути на естетичний контент оперного жанру як єдиний й цілісний, такий, що передбачає поєднання усіх основних естетичних якісних типових модусів, але зі спиранням, як на базовий, на трагічне відношення та трагедійну образну модель. Висновки. Оперна поетика дозволяє відкривати нові принципи естетичного усвідомлення та інтерпретації, розширювати коло естетичних категорій, пов’язаних як з музичною творчістю, так і з психологією свідомості. Специфічною рисою оперного естезису є прямування до ідеї довершеної людини, яка здатна поставати героєм життєвої та художньої події в силу власних моральних та творчих достоїнств, причому дані ідея взаємопов’язана з сукупністю інтерпретативних засобів, зосереджених у формі та змісті оперного твору. Звідси множинність втілення ідеї оперного героя – в тексті та позатекстом оперного твору, оскільки він ототожнюється з естетичною місією як провідних персонажів оперної дії, так і головних авторів і виконавців оперного задуму, учасників оперного естезису.
КАТЕГОРІЯ МУЗИЧНОЇ МОВИ У СУЧАСНОМУ МУЗИКОЗНАВСТВІ
Authors: Xiran Sun
Published: July 2024

Мета даної статті – виявити провідні підходи до явища музичної мови, що здатні надавати достатні критерії оцінки логічно-поняттєвих складових музично-творчої системи в різних її жанрових проявах, зокрема у галузі оперної творчості. Методологія роботи зумовлюється розвитком імагологічного підходу до явища музичної мови, до якого включені семіологічні та естетико-психологічні характеристики. Теоретичний аналіз передбачає розвиток категорій жанру, стилю, композиції; певна увага приділяється дискурсивному методу у музикознавстві та музичній творчості. Наукова новизна даної статті визначається теоретичною актуалізацію мовознавчих аспектів сучасного музикознавства. Оновлюється системний дискурсивний принцип вивчення музичної мови у єдності з музичним мовленням, у контексті загальної логіки музичної композиції, у зв’язку зі специфічними музичними поняттями; провідною одиницею музичної мови –мовлення виступає образ, як те, що і мислиться, й звучить, має і певні знакові, і значимі якості. У висновках статті зазначається, що образна природа музичної мови, як те, що найбільше визначає її семіологічну специфіку та художню своєрідність, найповніше розкривається в оперній творчості, оскільки жанрова сфера опера надає допоміжних комплексних засобів для виявлення й підсилення музично-мовної семантики. Взагалі словесні чинники, зокрема з боку музикознавчих номінацій, сприяють уточненню й розвитку музичного мовлення, також виробленню нових конститутивних рис музичної мови як автономної логіко-операціональної системи, з власними узагальненими «програмами» опрацьовування звукової дійсності. В оперному творі дане опрацьовування набуває наочності та сюжетно-дієвої (подієвої) оформленості, також найближчим чином підводить до образу – ідеї Людини, як головного предмету, і референту і сігніфікату, будь-якого музичного висловлення.
СПЕЦИФІКАЦІЯ ЕСТЕТИЧНИХ ЯКОСТЕЙ ВІРТУОЗНОСТІ У ФОРТЕПІАННОМУ ВИКОНАВСТВІ
Authors: Wen Wen
Published: July 2024

Мета даної статті – визначити естетичні передумови та доцільність віртуозності як якісного показника технічної оснащеності й образної ерудиції, психологічної зрілості музиканта-виконавця. Дана мета актуалізує звернення до специфічної ігрової природи фортепіанного виконавства – висвітлення багаторівневості та багатофункціональності прояву феномена гри у фортепіанній музиці, від безпосередньо презентованої інструментальної техніки до контамінації-перетворення складних художніх ідей у свідомості виконавця та у музичному звучанні, до «гри смислів» та зі смислами, що пробуджує нові естетичні інтенції у слухацькій свідомості. Методологія роботи зумовлюється єдністю жанрово-стильового та семантичного підходів у руслі аксіологічного; пропонується розвиток естетико-інтерпретологічного методу, котрий дозволяє запроваджувати акмеїчні поняття та оцінки. Наукова новизна статті обумовлена принциповою зміною у підході до явища віртуозності у музично-виконавській творчості, зокрема у фортепіанній сфері, за яким дане явище розглядається з боку естетичної презумпції та результативності музично творчого процесу. Вперше пропонується поєднувати віртуозність з довершеністю та акмеїчністю, як індивідуально-авторськими, водночас музично-композиційними оцінними критеріями. Таким чином запроваджується поглиблене аксіологічне дослідження природи та якостей віртуозності, відкриваються її структурно-концептуальні та почуттєво-образні призначення. Висновки. Явище віртуозності є необхідною стороною сучасної фортепіанно-виконавської практики, розуміється як універсальна тенденція у прагненні досягти професійної досконалості, також як індивідуальний спосіб мислення й художнього діяння, що передбачає як жанрове, так і стильове підґрунтя, водночас веде до авторизації творчого методу, способу мислення, виражає намір виконавця досягти найвищого рівня художнього впливу та самоздійснення, тобто передбачає особистісний акмеїчний аспект.
