Authors: Guan Huiyuan , Bai Yongping , Zhang Chunyue
Published: September 2022

Reasonable identification of the ecosystem security space and pattern restoration for the Yellow River Basin will be significant for facilitating future ecological protection and restoration projects. This study employs ecosystem services and landscape connectivity to discern ecological source areas and conducts an optimization evaluation method of resistance surfaces and the minimum cumulative resistance (MCR) model to identify the ecosystem security pattern of urban agglomeration. Then, restoration measures are proposed. The results indicate that: (1) There are 46 ecological source areas in the ecosystem security patterns of the Lanxi urban agglomeration, with a total area of 8199.249 km2. Moreover, in terms of spatial distribution, ecological source areas are sparse in the east while crowded in the west of the Lanxi urban agglomeration and are mainly composed of natural reserves, forest parks, and farmlands. (2) The ecosystem security patterns contain 914 ecological corridors with a total length of 62,970.181 km, most of which are short-distance corridors, being dense in the part of the northwest with a webbed feature. (3) The study adds 10 ecological source areas to restore the ecosystem security pattern and ecological corridors to improve the rationality of the ecosystem security pattern. Meanwhile, this study proposes restoration measures to protect the ecological environment by defining the levels of ecological security in order to provide a reference for the government to formulate policies and regulations.

Published: September 2022

Organising the 2020 European Football Championship was fraught with the uncertainties of the pandemic period. Budapest hosted its four allocated matches during the postponed event without stadium capacity restrictions. Drawing on both social exchange theory (SET) and social representation theory (SRT), the study aimed to investigate how the level of fear of COVID-19 before the start of Euro 2020 influenced the perception of the tournament among residents of Budapest. Data were collected by telephone interview during the five days preceding the event based on a representative sample of Budapest residents (n = 1003, adult population aged 18 years and over), accounting for gender, age and place of residence. Cluster analysis identified three groups of residents based on fear of coronavirus: concerned, neutral and unconcerned. Although our study only investigated the opinions of residents in one host city, the relevance of the research appears compelling in that it highlights the crucial role of COVID-19 in influencing responses to the expected impact of Euro 2020. Examining the views of local residents and understanding the factors that influence their opinions play a key role in more successful and sustainable delivery of sporting events.

Published: September 2022

In this paper, we examine the changes in the structural, economic and managerial characteristics of dairy cow farms during their shift towards a new business model that operates under a highly intensified system. Based on farm accounting data from Greek dairy farms for the 2004–2017 period, the main technical and financial indicators are estimated and compared to provide a clear picture of the structural adjustment of the dairy cow sector during the last two decades. The outcomes and the implications described herein are relevant for specialized dairy farms in most European countries. The results indicate that modern farms breed a larger number of cows, achieve a higher milk yield, rely on high compound feed intakes and operate under an intensive pattern. This trend is even more evident in larger farms with an entrepreneurial nature, whose structural adjustments occurred in a more concise and effective manner. The latter benefited from a downward shift in their long-term average cost curves and the resulting economies of scale, achieving reasonable gross margins despite the ever-increasing feeding costs. Nowadays, the European dairy cow sector faces major economic, social and environmental challenges that must be properly addressed to secure its survival. The findings of this study provide insights concerning the efficient financial management of dairy farms that can support the development of strategies and policy recommendations that will enhance the resilience and sustainability of the sector.

Authors: Yang Bin , Zhu Xin , Liu Minzhang , Lv Zhihan
Published: September 2022

Under low outdoor temperature and high humidity, frost easily forms on the Heat Exchanger (Exchanger) surface on the outdoor side. The formation and growth of this frost layer will seriously impact the Exchanger’s heat extraction process and the system’s energy efficiency, triggering malfunction in the compressor. To this end, this work first analyzes the formation and growth mechanism of Exchanger surface frosting and condensation. It then summarizes the current research status of Machine Vision (MV) technology in defrosting and decondensation. Further, it previews the follow-up research direction. The experimental findings show that MV technology can automatically observe frost and dew, guaranteeing a real-time understanding of the frost layer. Directly obtaining the frost and dew information from the image can significantly save human resources and improve efficiency.

Authors: Dong Jun , Chen Zhenjie , Dou Xihao
Published: September 2022

The development of renewable energy is of great significance to relieve the pressure on the energy supply and promote the low-carbon operation of the power system. However, the volatility of renewable energy, especially wind and solar energy, has a great impact on the safe and reliable operation of the power system. If we want to introduce renewable energy and ensure the safe and reliable operation of the power system, it is necessary for the power system to provide enough flexibility. Northwest China is rich in natural resources and an important area of power supply in China, which also faces the problem of insufficient flexibility. Therefore, based on the power system development and natural conditions in northwest China, this paper studies the key factors affecting the flexibility of the power system when renewable energy accounts for a large proportion, and proposes measures to improve the flexibility of the power system by using the power system optimization tool Flextool developed by IRENA.

Published: September 2022

This study aims to obtain a desirable 3D printing product based on the knowledge of the material and suitable printing parameters. This study used high-methoxy pectin (HMP) as the ingredient of pectin jelly candy to understand the effect of different pectin concentrations and printing parameters (nozzle height, extrusion rate, printing layer height, nozzle movement speed, and nozzle diameter). Machine learning was used to learn and analyze the data of different 3D printing parameters to find out a suitable parameter. Rheological analysis revealed that a 16% pectin (w/v) concentration had the height of G′ and G″, and all pectin jelly candy showed the characteristic of shearing thinning. A parameter analysis decision tree revealed that the pectin concentration of 12–14% (w/v), printing layer height below 1.5 mm, extrusion rate below 0.305 mm3/s, nozzle height above 0.5 mm, and printing rate of 5–10 mm were able to allow pectin jelly candy to be printed with an error below 5%. Machine learning helps researchers find appropriate parameters and reach the design of molding height quickly, and it helps them discuss how molecule interaction causes different 3D printing results.

Effect of an Antioxidant and a Compatibilizer on the Mechanical Properties of Virgin and Thermally Aged Polypropylene Drawn Fibers
Authors: Tsioptsias Costas , Gkouzouma Georgia , Leontiadis Konstantinos , Tsivintzelis Ioannis
Published: September 2022

Polypropylene (PP), like all polymers, is susceptible to various forms of aging. Drawn fibers exhibit increased mechanical properties; however, the drawing results in non-equilibrium (decreased entropy) structures, due to the orientation of the polymer chains. Consequently, the drawn fibers are susceptible to an additional form of physical aging. In this work, the effect of common industrial additives on the mechanical strength of virgin and thermally aged PP fibers was studied. Thermogravimetry and tensile strength tests were used to characterize the drawn fibers, before and after physical thermal aging. PP drawn at 120 °C and at a drawing ratio of 7 exhibited a tensile strength of 549 MPa, while the incorporation of an antioxidant and a compatibilizer lowered the tensile strength down to 449 MPA. This reduction was related to the constraint of chain alignment due to the low molecular weight and poor dispersion of the additives. Depending on the aging temperature, shrinking occurred to different extents in pure PP fibers, accompanied by a 6–7% reduction in tensile strength. The fibers with incorporated additives exhibited higher rate and degree of shrinking. Briefly, the incorporation of such additives in drawn PP resulted in the deterioration of the fibers’ mechanical tensile properties. Since such additives have an indisputable value for non-drawn samples and their usage is necessary for various reasons also in drawn samples, e.g., for their protection from chemical aging/decomposition, additives specific for drawn samples should be developed.
An Attempt to Construct an Activity Cycle Catalog with Kepler Long-Cadence Light Curves
Authors: Shen Yu-Fu , Zhao Gang , Bird Sarah A.
Published: September 2022

Many stars show activity cycles like the Sun. Kepler has gathered ∼200,000 light curves. Most of the Kepler stars only have long-cadence light curves, which limits their applicable methods. Some metrics, for example Sph, are effective for long-cadence light curves but require rotation periods. In order to improve the utilization of Kepler light curves, we introduce and use the smoothness metric. The smoothness metric is able to analyze stars without a measured rotation period and is applicable for long-cadence light curves. We test and validate our metric, resulting in the detection of the 11 years solar cycle and a 457 days cycle for our prototype star KIC 9017220. We analyze 92,084 Kepler long-cadence light curves, and as our main results, we detect 4455 magnetic activity cycle candidates, but about 20 percent are false cycles and 50 percent are lower limits of the real cycles, and we analyze their causes in detail. As an investigation into the performance of our method, we simulate disturbance factors and prove that the p-value test is invalid under certain circumstances.
Status of Cosmic Microwave Background Observations for the Search of Primordial Gravitational Waves
Authors: Battistelli Elia Stefano , Capalbo Valentina , Isopi Giovanni , Radiconi Federico
Published: September 2022

The cosmic microwave background (CMB) is one of the most powerful tools for cosmology. Its polarization could have imprinted the sign of an inflationary background of gravitational waves, which is supposed to have originated at 10−38/10−35 seconds after the Big Bang. Detecting this background is extremely difficult because of the weakness of the signal (if any) left on the CMB polarization and because of the need to control the systematic effects. Additionally, the presence of astrophysical foregrounds, the possibility of leakage from curl-free to curl-like components, including gravitational lensing, and the instrumental noise and systematics, require sensitive detectors and smart systematic effect control. We discuss the experimental efforts spent in this field, highlighting the key observational difference and the choice that could lead, in the near future, to the detection of the curl component of the CMB polarization, a clear sign of the inflationary expansion.

Published: September 2022

Cucumber green mottle mosaic virus (CGMMV) belongs to the Tobamovirus genus and is an important quarantine virus of cucurbit crops. Seedborne transmission is one of the principal modes for CGMMV spread, and effective early detection is helpful to prevent the occurrence of the disease. Quantitative real-time reverse-transcription PCR (RT-qPCR) is a sensitive and rapid method for detecting CGMMV nucleic acids, but it cannot distinguish between infectious and noninfectious viruses. In the present work, a propidium monoazide (PMA) assisted RT-qPCR method (PMA-RT-qPCR) was developed to rapidly distinguish infectious and inactive CGMMV. PMA is a photoactive dye that can selectively react with viral RNA released or inside inactive CGMMV virions but not viral RNA inside active virions. The formation of PMA-RNA conjugates prevents PCR amplification, leaving only infectious virions to be amplified. The primer pair cp3-1F/cp3-1R was designed based on the coat protein (cp) gene for specific amplification of CGMMV RNA by RT-qPCR. The detection limit of the RT-qPCR assay was 1.57 × 102 copies·μL−1. PMA at 120 μmol·L−1 was suitable for the selective quantification of infectious CGMMV virions. Under optimal conditions, RT-qPCR detection of heat-inactivated CGMMV resulted in Ct value differences larger than 16 between PMA-treated and non-PMA-treated groups, while Ct differences less than 0.23 were observed in the detection of infectious CGMMV. For naturally contaminated watermelon leaf, fruit and seedlot samples, infectious CGMMV were quantified in 13 out of the 22 samples, with infestation levels of 102~105 copies·g−1. Application of this assay enabled the selective detection of infectious CGMMV and facilitated the monitoring of the viral pathogen in watermelon seeds and tissues, which could be useful for avoiding the potential risks of primary inoculum sources.

Background: We conducted a longitudinal study to estimate immunity produced in response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among university students over seven months. Methods: All participants were attending a public university and resided in Pitt County, North Carolina. University students enrolled weekly for 10 weeks between 26 August 2020 and 28 October 2020, resulting in 136 young adults completing at least one study visit by 17 November 2020. Enrolled students completed an online survey and nasal swab collection at two-week intervals and monthly blood collection between 26 August 2020 and 31 March 2021. Results: Amongst 695 serum samples tested during follow-up, the prevalence of a positive result for anti-nucleocapsid antibodies (N-IgG) was 9.78%. In 22 students with more than one positive N-IgG serum sample, 68.1% of the group lost persistence of N-IgG below the positive threshold over 140 days. Anti-spike IgG antibodies were significantly higher among 11 vaccinated compared to 10 unvaccinated. Conclusions: In healthy young adults, N-IgG wanes below the detectable threshold within five months. S-IgG titer remained consistently elevated months after infection, and significantly increased after vaccination.
Stimulating Nitrate Removal with Significant Conversion to Nitrogen Gas Using Biochar-Based Nanoscale Zerovalent Iron Composites
Authors: Liu Siyuan , Han Xiao , Li Shaopeng , Xuan Wendi , Wei Anlei
Published: September 2022

For efficient and environmentally friendly removal of nitrate from groundwater, biochar-based nanoscale zerovalent iron composites were prepared, where biochar was derived from pine sawdust at 4 different pyrolysis temperatures. The results show that biochar with different pyrolysis temperatures played a great role in both nitrate removal efficiency and nitrate conversion rate to nitrogen gas for the prepared composites. Specifically, the composite with biochar pyrolyzed at 500 °C, ZB12-500, showed the best performance in both nitrate removal and conversion to nitrogen gas. With an initial solution pH from 5 to 10, ZB12-500 maintained high removal efficiencies varying from 97.29% to 89.04%. Moreover, the conversion of nitrate to nitrogen gas increased with the initial nitrate concentration, and it reached 31.66% with an initial nitrate concentration of 100 mg/L. Kinetics analysis showed that the nitrate removal process fit well with a two-compartment first-order kinetic model. Meanwhile, the test of nitrate removal by ZB12-500 in synthetic groundwater showed that HCO3− and SO42− limited nitrate removal but improved nitrate conversion to nitrogen gas. Furthermore, the nitrate removal mechanism suggested that biochar could facilitate electron transfer from zero valent iron to nitrate, which led to high nitrate removal efficiency. In addition, the interaction of ferrous ions and the quinone group of biochar could increase the nitrate conversion to nitrogen gas. Therefore, this study suggests that ZB12-500 is a promising alternative for the remediation of nitrate-contaminated groundwater.
Assessing Riverbed Surface Destabilization Risk Downstream Isolated Vegetation Elements

Published: September 2022

A few decades ago, river erosion protective approaches were widely implemented, such as straightening the river course, enhancing riverbed/bank stability with layers of concrete or riprap, and increasing channel conveyance capacity (i.e., overwidening). However, recent research has established that such practices can be tremendously costly and adversely affect the rivers’ ecological health. To alleviate these effects, green river restoration has emerged as a sustainable and environmentally friendly approach that can reduce the negative impact of the riverbed and bank destabilization and flooding. One of the typical green restoration measures, especially for instream habitat improvement, is the establishment of instream vegetation, which leads to a more diversified flow regime, increasing habitat availability and serving as refugia for aquatic species. Within the perspective presented above, flow–vegetation interaction problems for several decades received significant attention. In these studies, rigid rods have commonly been used to simulate these vegetative roughness elements without directly assessing the riverbed destabilization potential. Here, an experimental study is carried out to investigate the effect of different instream vegetation porosity on the near-bed flow hydrodynamics and riverbed destabilization potential for a range of simulated vegetation species. Specifically, the flow field downstream, four distinct simulated vegetation elements is recorded using an acoustic Doppler velocimetry (ADV), assuming about the same solid volume fraction for the different vegetation elements. In addition, bed destabilization potential is assessed by recording with optical means (a He-Ne laser with a camera system) the entrainment rate of a 15 mm particle resting on the uniform bed surface and the number of impulses above a critical value. Results revealed that the number of impulses above a critical value at the normalized distance equal to two is a good indicator for cylinder and five for other vegetation to assess the riverbed destabilization potential. The experimental findings from this study have interesting geomorphological implications regarding the destabilization of the riverbed surface (removal of coarse particles induced by high magnitude turbulent impulses) and the successful establishment of seedlings downstream of instream vegetation.
Performance Evaluation of Water Services in Italy: A Meta-Frontier Approach Accounting for Regional Heterogeneities
Authors: lo Storto Corrado
Published: September 2022

Data relative to the water services industry in Italy indicate that there is a serious infrastructure gap between the southern regions and isles and the rest of the country. In these geographical areas, water utilities are provided with substantial public grants from the central and local governments to support investments necessary to mitigate the infrastructure divide by increasing capacity and improve service quality. This paper implements a meta-frontier non-parametric approach based on a data envelopment analysis (DEA) to evaluate the efficiencies of 71 Italian water utilities, accounting for the differentiated contexts in which they operate. A short-term perspective was assumed to estimate efficiency, considering the production factors associated with the infrastructure assets as non-discretionary inputs in the specification of the meta-frontier model. The results showed that water utilities operating in the southern regions and isles suffer from an efficiency gap in comparison to those in the northern and central regions. The average efficiency gap was 9.7%, achieving 24.9% in the worst case. Moreover, a more in-depth analysis focusing on the water utilities in the southern regions and isles indicated that scale inefficiencies might be an important determinant of such an efficiency gap. Indeed, slightly more than 69% of the water utilities operated at increasing returns to scale. Evidence from this study raises concern about the appropriate structure of the Italian water service industry and, particularly, the optimal size of the utilities and the financial sustainability of water services in the southern regions and isles.

In overcoming Iron Deficiency Anemia and stunting, the Indonesian government seeks to increase the content of iron (Fe) and zinc (Zn) in milled rice through fortification and biofortification. Fortivit rice is rice fortification produced by BULOG. Inpari Nutri Zinc is biofortified rice grown from plant breeding by the Ministry of Agriculture, which ID Food currently produces. This study is a continuation of the IFFRI research collaboration on the Implementation and Research of Precision Agriculture in Biofortified Rice Strain. This study aimed to characterize the biofortified rice as a result of fertilization recommendations in previous studies and compare biofortified rice with fortified rice in several aspects, including micronutrient contents especially Zn, organoleptic, and production

costs. The highest Zn content of Nutri Zinc was found in the aleuron, so that the post-harvest process caused a decrease in Zn level. The differences in fertilization recommendations have an impact on the Zn content in brown rice, each layer of aleurone, and the rice endosperm. The nutritional content of Fortivit and Nutri Zinc rice was relatively the same as non-fortified/biofortified rice. The washing and cooking process caused a decrease eof about 4 percent in Zn content in fortified rice, while in biofortified rice, there was relatively no decrease. Although there was a decrease in Zn in fortified rice, overall, the Zn content was still much higher than in biofortified rice. Based on the results of the hedonic test, fortifed rice (Fortivit) was the most preferred for all sensory attributes. In biofortified rice (Nutri Zinc), respondents prefer the rice with 100 percent milling grade the most. Fortivit rice had a faster research time and a lower estimated cost in research. In the contrary, it had a higher estimated cost in production than Nutri Zinc rice. Nonetheless, the selling price of Fortivit rice is cheaper than Nutri Zinc rice on the market.

Authors: Medvedeva O. , Chilikin A.
Published: September 2022

The limitation of gas distribution organizations (GDO) in financial resources that can be directed to continuous modernization and maintenance of gas distribution network facilities in a condition that provides the necessary level of safety requires solving an optimization problem. In turn, the task of optimizing the resources spent on carrying out the relevant activities requires the selection of criteria against which the goal of the activities will be determined and its achievement through these activities will be assessed.

An analysis of the indicators of the level of reliability and quality of services provided in the production and transmission of heat and electricity indicates the following differences in the range of indicators. The obtained results of the analysis make it possible to collect the required initial data on the actual values of the desired indicator for a certain period and develop a mechanism for managing the costs of gas distribution companies to ensure the required level of security of gas distribution networks.

The article proposes a methodology for planning work on modernization, overhaul and reconstruction of gas distribution network facilities, taking into account the safety indicator based on the value of the failure rate parameter for various types/types of facilities and their actual technical condition.

The issue of assessing the stress state of protective and decorative coatings, depending on the porosity in the contact zone "coating-substrate" is considered. Several schemes are considered: the absence of pores, the pores are filled with a paint composition, the pores are not filled with a paint composition. To assess the stress state of the coatings, the SCAD Office software module is used. It has been established that the presence of pores in the contact zone leads to the appearance of a more inhomogeneous stress state. When a pore is filled with a paint composition, the maximum stresses in the coating occur in the zone of contact between the coating and the substrate. In the absence of filling the pores with paint, the maximum stresses occur on the surface of the coating. The influence of the substrate on the change in the values of internal thermal stresses is revealed. Stresses in coatings on a claydite-concrete substrate are significantly lower compared to the use of heavy concrete as a substrate. The ratio of maximum thermal stresses and long-term cohesive strength is analyzed. It is established that cracking is possible in the polymer lime coating from the action of temperature stresses in the period from August to January

Magnetic fluid hyperthermia (MFH) is a new generation cancer treatment method under development. One of the challenges that arise in the practical applications of MFH is the limited control of magnetic nanoparticles (MNP). In order to overcome this problem, new approaches are being investigated in MFH tests. Localization of MNP oscillations can be achieved through static magnetic field-free region (FFR) and static magnetic field (SMF) gradients generated by permanent magnets or electromagnets. In this study, Helmholtz coils were used as SMF source to generate gradient patterns (GPs). Finite element method simulation was used to predict GPs that would emerge in the study area. An experiment platform was produced in which the GP would be generated with parametric current changes. Measurements were taken when source currents were (1.1, 1.1 ), (2.2, 2.2), (4.4, 4.4) and (2.2, -2.2) A, respectively. It was observed that FFR form could be manipulated with coil current. The mapping of the GPs and determining FFRs for the use of localized MFH were discussed for the first time in this study. The findings provide insight into which GP is appropriate in which situations in localized MFH.

Authors: Mendoza Yuseth , Pinto Bismarck
Published: September 2022

La presente investigación tuvo como objetivo, determinar si los jóvenes de la Universidad Católica Boliviana “San Pablo”, tienen una actitud favorable o desfavorable hacia el proceso de emancipación y desvinculación familiar. Para lograr cumplir este objetivo se realizó una investigación de tipo descriptivo-comparativo, de carácter cuantitativo. Por tanto, se trabajó con 353 estudiantes, del cuarto al octavo semestre de las distintas facultades de la universidad, en función a una escala propia, denominada actitudes hacia el proceso de la emancipación y desvinculación familiar (Pinto y Mendoza 2019). Los resultados obtenidos en función al coeficiente de Alpha de Cronbach, determinaron la confiabilidad y consistencia del instrumento, el cual, manifiesta una actitud favorable hacia el proceso de emancipación y desvinculación familiar, puesto que, los 36 elementos de la escala, reflejaron un alto nivel de confiabilidad, implicando la consistencia y validez interna del instrumento. Del mismo modo, el resultado obtenido al analizar los rangos de edades, identificó que los jóvenes entre los 24 a 26 años de edad, tienen una mayor predisposición hacia este proceso, igualmente, al efectuar la comparación entre el sexo femenino y masculino, se determinó, que no existe una diferencia significativa entre ambos, por último, entre los tres componentes que constituyen una actitud, el más sobresaliente es el cognitivo, posteriormente el afectivo y por último se encuentra el conductual, por ende, se puede concluir, que la escala elaborada, tiene una excelente validez, reflejando que el instrumento, verdaderamente mide las actitudes hacia el proceso de emancipación y desvinculación familiar.

Problems that stand out among teenagers are sexuality, HIV/AIDS, and drugs. The level of knowledge about HIV/AIDS in adolescents is high, but adolescents continue to engage in unsafe sexual activities and are at risk of contracting HIV/AIDS in dating. This will increase the incidence of contracting HIV / AIDS in adolescents. This study aims to determine whether there is a relationship between knowledge about HIV/AIDS and free sex behavior in adolescents. This type of research is a correlational study with a cross-sectional approach. The samples used were students of classes VIII and IX at SMP Tri Guna Bhakti Surabaya; as many as 151 people were selected using a total sampling technique. The measuring instrument used is a questionnaire containing 15 questions about knowledge about HIV/AIDS and ten questions about free sex behavior in adolescents. Analysis of the data used is chi-square. respondents who have risky behavior are respondents with less knowledge, where the most number is 59%. At the same time, respondents who behave not at risk are respondents with sufficient knowledge, as much as 49%. The Chi-Square test produces a significant correlation with p = 0.000. This study's results found a relationship between knowledge about HIV/AIDS and free sex behavior in adolescents at Tri Guna Bhakti Junior High School Surabaya.
ФЕНОМЕН "ЗАХІДНОЇ" ГЛОБАЛІЗАЦІЇ ТА СИМУЛЯКР ЦИВІЛІЗАЦІЇ
Authors: Утюж І. , Сайтарли І. , Павленко Н.
Published: September 2022

У статті досліджується співвідношення таких постмодерністських явищ, як глобалізація, "масовізація" та національно-економічний центризм. Зроблено висновок, що це національний економічний центризм, який є серйозною альтернативою глобалізації, тоді як проекти так званої цивілізаційної ідентичності виступають як симулякри. Однак ця альтернатива лише посилює економічну параною та зміцнює релігію комфорту в сучасних масових суспільствах. Інакше кажучи, в рамках посилення національних економік відтворюється єдина соціальна модель – масове суспільство – за рахунок відтворення тієї ж моделі збільшеного виробництва, що потребує такого ж збільшення споживання. Отже, існування іншого суспільства, протилежного суспільству споживання, просто неможливе саме по собі, тобто процес знищення людства, як здатності до афективного (лібідинального) контролю, лише зростає. Не залишилося майже ні лагідності, ні скромності, що дедалі більше загострює етичний контекст сучасних суспільних досліджень. Як видається, можна припустити, що криза лібералізму відображає, перш за все, кризу самого капіталізму, його способу організації соціального життя, який сьогодні намагається захистити себе своїми перевіреними практиками.

Тому критичну соціальну теорію у формі "теорії масового суспільства" слід загалом розглядати як окрему концептуальну соціальну модель у контексті глобалізації, яка нині посилює гомогенізацію культур у плані їх трансформації у загальну "вульгарну" чи "масову" культуру.
ОСОБИСТІСТЬ VERSUS ЗАГАЛ У ХУДОЖНІЙ РЕЦЕПЦІЇ ЛЕСІ УКРАЇНКИ
Authors: Чаплінська О.
Published: September 2022

У статті встановлено, що важливою засадою філософії українського неоромантизму є романтична тенденція осмислення мистецтва як сакрального акту, що спроможний згуртувати і підняти на боротьбу. У статті окреслено неоромантичну модель розуміння ролі митця у процесах націєтворення. Неоромантичне трактування Лесею Українкою поета як охоронця чи опікуна духовних скарбів тяжіє до гайдеґґерівського визначення людини як пастуха буття. У створенні поетесою образів-символів простежуються дотримання принципів концепції прометеїзму, принципів індивідуалізму Ф. Ніцше, Г. Ібсена. принципу мужнього оптимізму Л. Стивенсона.

Обґрунтовано, що перебуваючи у стані конфлікту між "субстанційністю" та "зовнішнім" світом, герої "Вавилонського полону" і "Оргії" опиняються перед дилемою екзистенційного вибору подальшого вектору творчої діяльності. Й Елеазар, й Антей здійснюють вибір на користь національного обов’язку, підпорядковуючи йому творчу свободу. У художньо-філософській концепції Лесі Українки пріоритет належить концепту волі, що потрактовується на засадах шопенгаурівського волюнтаризму.

У контексті структурно-функціонального аналізу доведено, що воля функціонує на двох рівнях: по-перше, воля кожного свідомого патріота спрямовується назовні (тобто на боротьбу за визволення з-під іноземного гніту), і, по-друге, в глибину власного єства (придушення жадоби слави в серці). Погляди мисткині базовані також на ідеї, що митець спроможний змінити інертну, в-собі-сущу етнічну масу, й перетворити її на для-себе-сущу націю, що в свою чергу сприятиме формуванню нового суспільства – "союзу самостійних особистостей". У такий спосіб неоромантизм Лесі Українки стає орієнтиром українського державотворення, проголошує дихотомічну єдність "Я-самості" та "Ми-цілісності", у якій органічно поєднуються особистісна та природно-духовна складові як індивідуального "Я", та і національного "Ми". Для Лесі Українки вдосконалення себе, піднесення свого буття на вищий рівень проектується не на егоцентричну мету, а має альтруїстичні цілі (прометеївський дух).
