Published: November 2024

Pathways to net-zero reduce GHG emissions and improve air quality, but the magnitude and distribution of these improvements will depend on specific mitigation decisions, such as the amount of carbon dioxide removals (CDR). Here, we combine a series of models and datasets to analyze community-scale PM2.5 impacts across the contiguous U.S. of net-zero scenarios with different levels of CDR. Both the high- and low-CDR scenarios avoid many PM2.5-related deaths compared to a reference scenario, decreasing from around 200,000 to 160,000 and 130,000 deaths in 2050 in the high- and low-CDR scenarios, respectively. However, the low-CDR pathway leads to lower residual emissions and brings larger health benefits that disproportionately affect non-white and low-income groups. Our results thus suggest that in the absence of concerted transition planning, large-scale CDR deployment could be at odds with the equal distribution of climate mitigation-related health benefits in the U.S.
Addiction, Doughnut, or Extended Self? An Analysis of Interpretive Concepts of Nomophobia
Authors: Li Jiayi , Chen Wenfeng
Published: November 2024

Nomophobia refers to the anxiety individuals experience when unable to effectively access the internet. Traditional explanatory frameworks often interpret this phenomenon as withdrawal symptoms, leading to an over-pathologization of daily behaviors. Neutral theories, on the other hand, view nomophobia as a psychological manifestation of unmet connectivity needs but often fail to acknowledge the psychological benefits of digital technology. The attachment theory perspective interprets nomophobia as separation anxiety, yet logical inconsistencies remain. Self-extension theories consider digital networks as part of the individual self but insufficiently explore the systemic and unique characteristics of the internet. After evaluating and comparing these perspectives, this study introduces the concept of "virtual ability expansion through networks" as a complementary enhancement to existing theories. Overall, the conceptual landscape surrounding this topic is characterized by significant overlap and ambiguity. Future research should aim to delineate the boundaries and applicability of these concepts to better understand the ambivalent “love-hate”human-Internet relationship.

Authors: Bhim Bahadur Khadka  , Anjani Kumar Malviya
Published: November 2024

The study aims to investigate the influence of the personal values of tourists on their attitudes, subjective norms and perceived behavioural control. Furthermore, the study aims to evaluate the subsequent impact of these factors on tourists' intentions to visit eco-friendly destinations. Additionally, the study examines the moderating role of environmental consciousness in shaping the relationship between personal values and attitudes towards sustainable tourism practices. The study uses convenience sampling to gather data from tourists at two distinct eco-friendly tourist sites, Bulbule and Kankrebihar, located in the Surkhet district of Nepal. The study involves accessing the reliability and validity of the measurement model, followed by path analysis of the structural equation modelling, followed by path analysis of the structural model. The study conducts confirmatory factor analysis to validate the latent constructs. Survey data from 405 tourists reveal significant positive relationships between tourists' values of resultant self-transcendence and conservation and TPB factors, except for the relationship between conservation and perceived behavioural control. Moreover, TPB factors and perceived green image positively influence tourists' intentions to visit eco-friendly destinations. Likewise, environmental consciousness moderates the relationships between the two Schwartz values and attitudes. In addition, the study offers valuable implications for sustainable tourism operators and eco-friendly destination managers, highlighting the need to consider individual values and environmental consciousness in promoting eco-friendly behaviours.

Authors: Veetihotra Vasishtha  , MS Toor
Published: November 2024

The Impact of Foreign Aid and Domestic Revenue on Government Expenditure in Nepal: An Error Correction Approach explore the impact of foreign aid and domestic revenue on government expenditure in Nepal using an Error Correction Model and time series data from 1975 to 2022. The study aimed to find both short- and long-term correlations between these factors.
The empirical findings demonstrated that both foreign aid and domestic revenue had a statistically significant and favourable influence on government expenditure in the short and long term. More precisely, there was a direct correlation between a 1 percent increase in foreign aid and a 0.42 percent increase in government expenditure, while a 1 percent increase in domestic revenue was associated with a 0.58 percent increase. The Error Correction Model confirmed a cointegrating relationship, suggesting a stable equilibrium between the variables and indicating that deviations from the long-run equilibrium were corrected over time.
The study concluded that external assistance and domestic resource mobilization were essential for financing government spending in Nepal. These findings underscored the importance of implementing effective policies to attract foreign aid and enhance domestic revenue collection to support sustainable economic growth.
Webwriting a realizacje tekstów w popularnych serwisach internetowych – od teorii do praktyki
Authors: Grażul-Luf Agnieszka
Published: November 2024

Web writing involves the application of specific principles crucial for online communication, including segmentation, syntactic and lexical simplicity, and the strategic use of marketing tools. These practices significantly influence text dissemination and reception efficacy without compromising traditional standards of correctness and stylistics in media and public relations. Training professionals for electronic media necessitates interdisciplinary competence encompassing journalism, communication, and marketing, with web writing techniques constituting a fundamental component of this preparation. However, the dynamic evolution of the online media landscape has widened the gap between theoretical web writing principles and their practical application in professional electronic media contexts. Analysis of web publications reveals pervasive deviations from ideal practices, which often stem not from the incompetence of the author but from the expectation of the employer. This study aims to illuminate this disparity by examining the implementation of web writing principles through a content analysis of three texts from prominent websites. Findings indicate that these publications prioritise capturing reader attention for marketing purposes over informational or entertainment value.

Authors: Lima Legunes Eric , Mühl Diego Durante , Oliveira Letícia de
Published: November 2024

A produção de algodão no Brasil desempenha um papel significativo na economia agrícola do país, gerando empregos, renda e divisas por meio de exportações. No entanto, os produtores de algodão enfrentam diversos riscos, como o risco de oscilações nos preços das commodities agrícolas. As flutuações de preço podem impactar a viabilidade da atividade agrícola, influenciando no resultado econômico. Nesse contexto, o uso de estratégias de gestão de risco torna-se crucial para minimização de riscos. O hedge é um instrumento financeiro que protege seu adotante contra variações adversas de preço e reduz o risco de mercado. Por meio de contratos futuros os produtores podem determinar o preço futuro de venda de suas safras, garantindo previsibilidade de receita e minimizando o impacto da volatilidade de preços do mercado. Assim, o objetivo desse estudo é analisar cenários de aplicação de hedge para proteção dos produtores de algodão contra variações nos preços. Para tanto, realizamos uma revisão exploratória da literatura sobre o tema e uma análise quantitativa simulando a utilização de uma estratégia de hedge por um produtor de algodão em pluma em três safras. A utilização de hedge apresentou vantagens e desafios para o agricultor. Ao compreender a importância dessas ferramentas na gestão de risco, os produtores podem tomar decisões informadas e proteger os resultados de sua atividade.

Authors: Козлова Д. С. , Кучменко О. Б.
Published: November 2024

Вітамін D є важливим регулятором багатьох фізіологічних процесів, включаючи метаболізм кальцію, підтримання здоров’я кісткової системи, функціонування імунної системи та процеси еритропоезу. Дефіцит вітаміну D у вагітних жінок може впливати на показники крові, зокрема, викликати анемію та порушення метаболізму заліза. Наявність зв’язку між рівнем вітаміну D та гематологічними показниками у вагітних потребує подальшого дослідження. Метою даного дослідження було оцінити зв’язок між рівнем вітаміну D (25(OH)D) та гематологічними показниками у жінок в першому триместрі вагітності в різних вікових групах.
В дослідженні взяли участь 142 вагітні жінки, які були обстежені протягом квітня-травня 2024 року. Учасниць дослідження поділено на чотири групи за рівнем 25(ОН)D у крові та на дві вікові групи для аналізу змін в гематологічних показниках.
Було виявлено, що низькі рівні вітаміну D асоціюються зі зниженням показників гемоглобіну, еритроцитів, гематокриту та середнього об’єму еритроцитів, особливо в групі з дефіцитом вітаміну D (< 10 нг/мл). Також виявлено тенденцію до зниження кількості лейкоцитів та тромбоцитів зі збільшенням рівня вітаміну D.
Дефіцит вітаміну D може негативно впливати на гематологічні показники у вагітних жінок. Зокрема, вагітні з рівнем вітаміну D понад 30 нг/мл мали кращі гематологічні показники, що вказує на необхідність контролю та корекції дефіциту вітаміну D під час вагітності.

Published: November 2024

Manganese ions are toxic for the central nervous system and cause motor impairment. Zebrafish (Danio rerio) are widely used in neuroscience, psychopharmacology and toxicology. The study was aimed to investigate the effect of prolonged exposure to Mn ions on the serotonin (5-HT) system of the brain and the 5-HT controlled behavior in zebrafish. The studies were carried out on males and females of zebrafish line AB, which were divided into four groups: control and which were exposed to 0.1, 0.2 and 0.5 mM MnCl2 for 10 days (the drug was added to the aquarium water). Throughout the exposure, the locomotion of fish were continuously recorded and analyzed using DanioStudio software. On the 11th day of exposure, the behavior of the fish was studied in the novel tank diving test, then the levels of 5-HT, 5-hydroxyindoleacetic acid (5-HIAA), the activity of key enzymes in the synthesis and destruction of 5-HT, tryptophan hydroxylase (TPH) and monoamine oxidase (MAO), respectively, were determined in their brain by HPLC. Prolonged exposure to MnCl2 did not affect body mass, locomotor activity, time in the lower and upper thirds of the home aquarium, as well as locomotor and exploration activities, time in the lower and upper thirds in the novel tank diving test. Moreover, the prolonged exposure to MnCl2 did not affect 5-HT, 5-HIAA levels and MAO activity in fish brain. However, TPH activity was significantly increased in fish kept at 0.2 and 0.5 mM MnCl2. In an additional experiment, Mn ions were shown to increase the thermal stability of the TPH molecule in vitro. This stabilizing (chaperone) activity of Mn ions was demonstrated for the first time. The discovery of the chaperone activity of Mn ions will help to reveal the fundamental molecular principles and mechanisms of action of pharmacological chaperones.
Temperature dependence of structural parameters of thin films of polystyrene—fullerene С60/С70 nanocomposite according to neutron reflectometry data
Authors: Tropin T. V. , Avdeev M. V. , Aksenov V. L.
Published: November 2024

The temperature dependences of the structural parameters of thin films of polystyrene–fullerene C60/C70nanocomposites with a low content of nanoparticles in the vicinity of the glass transition temperature of the polymer matrix were studied by specular neutron reflectometry in the range 15–150°C. The obtained temperature dependences of film thickness were used to estimate the glass transition temperature of film composites. In the case of films with C60fullerene, the dependence had a standard form. The glass transition temperature of the composite film was found to decrease compared to the known value for the pure bulk polymer. In the case of films with C70fullerene, upon transition to high temperatures, a non-monotonic dependence of the film thickness was observed, which hindered the application of the general approach.

The processes of microrelief formation on the Si(100) surface under irradiation with a 30 keV Ga+ ion beam and a fluence of D = 1.25 × 1018–2 × 1019 cm–2 at incidence angles θ = 30°–85° was investigated. It was found that in the θ angular range 40°–70° faceted ripples were formed on the Si surface, and at θ = 30° sinusoidal ripples were formed. The experimental dependence of the wavelength of the periodic structure on the irradiation time λ(t) ~ tn, n = 0.33–0.35, was obtained. The average velocities of relief propagation and their direction relative to the direction of incident ions in the cases of θ = 30° and 40° were determined, which were –5.3 ± 0.6 and –6.3 ± 0.6 nm/s, respectively. The results obtained are discussed in detail within the framework of existing models of the formation of ripples on a surface under ion beam irradiation.

The formation of thin surface amorphous layers of nanoporous Ge with various morphology during low-energy high-dose implantation by metal ions of different masses 63Cu+, 108Ag+ and 209Bi+ of monocrystalline c-Ge substrates were experimentally demonstrated by high-resolution scanning electron microscopy. Analysis of the crystallographic structure of all nanoporous germanium layers obtained was carried out by reflected backscattering electron diffraction. It was shown that at low irradiation energies, in the case of 63Cu+ and 108Ag+, needle-shaped nanoformations were created on the c-Ge surface, constituting a nanoporous Ge layer, while when using 209Bi+, the implanted layer consists of densely packed nanowires. At high energies, the morphology of thin surface layers of nanoporous germanium changes with an increase in the mass of the implanted ions from three-dimensional network to spongy with separate discharged interlacing nanowires. General possible mechanisms of pore formation in Ge during low-energy high-dose ion implantation, such as cluster-vacancy, local thermal microexplosion, and point heating accompanied by melting, are discussed.
Study of the evolution of the structure of a high-entropy Al20Ni20Co20Fe20Cr20 alloy under the action of high pressures and temperatures
Authors: Menshikova S. G.
Published: November 2024

Electron microscopic and X-ray studies of the structure of a high-entropy submicrocrystalline AlNiCoFeCr alloy of equiatomic composition obtained by arc melting were performed. The alloy consists of a substitutional solid solution with a packing of components corresponding to the B2 structure based on a distorted bcc lattice. The average grain size of the B2 phase is 120 nm. The stability of the alloy with increasing temperature was studied. When the alloy is heated to 1650oC and subsequent solidification, an increase in the grain size of the B2 phase and the separation of several phases with different morphologies along the grain boundaries are noted in the structure. The effect of high pressure on the structure of the alloy after quenching from the liquid phase was studied. The structure of the sample obtained upon solidification at a temperature of 1650°C under a pressure of 5 GPa is different from the structure of the alloy obtained at a temperature of 1650°C by arc melting. Under thermobaric conditions, a structure of mixed phases of A1 and A2 types is formed in the alloy. The alloy has high hardness, the value of which, depending on the selected production conditions, varies from 4.8 to 5.5 GPa.

У науковій статті здійснено дослідження ролі ресторанів української кухні у формуванні та збереженні культурної ідентичності України, а також проаналізовано їх вплив на розвиток ресторанного бізнесу. Мета дослідження полягає в тому, щоб визначити, як національна кухня сприяє зміцненню національної самосвідомості та популяризації української культури в сучасних умовах, і дослідити економічний потенціал ресторанів української кухні в умовах ринкових відносин. Основна увага приділяється тому, що українська кухня, як важлива складова національної культури, відображає історичні, етнографічні та регіональні традиції України. Ресторани української кухні функціонують не лише як заклади харчування, але й виконують роль культурних майданчиків, популяризуючи українські традиції серед внутрішніх і зовнішніх споживачів. Важливі традиційні страви, такі як борщ, вареники та галушки, символізують національну самобутність і допомагають формувати позитивний імідж України на міжнародній арені. Стаття також висвітлює роль ресторанів у збереженні та відтворенні регіональних кулінарних традицій, які відображають різноманітність культурних практик усіх регіонів України. У цьому контексті проаналізовано діяльність окремих ресторанів української кухні, які активно інтегрують елементи культурної спадщини, відтворюють національні кулінарні традиції та сприяють розвитку ресторанного бізнесу через автентичність страв і культурні заходи. Крім того, стаття зосереджується на економічних аспектах функціонування ресторанів української кухні. Підкреслено їхній позитивний вплив на розвиток місцевої економіки, зокрема через підтримку локальних виробників та постачальників, створення робочих місць та стимулювання туристичної індустрії. Вивчено також їхній внесок у розвиток гастрономічного туризму, що підвищує інтерес іноземних туристів до української культури через національну кухню. У статті зазначається, що ресторани української кухні активно впроваджують інновації у своїй діяльності, використовуючи нові технології приготування їжі та сучасні маркетингові стратегії, що сприяє збільшенню клієнтської бази та розвитку ресторанного бізнесу в Україні. Ці заклади стають важливими майданчиками для популяризації української кулінарної спадщини як у країні, так і за її межами, а також відіграють важливу роль у підтримці національної ідентичності в умовах глобалізації. Таким чином, стаття показує, що ресторани української кухні не лише сприяють культурній ідентифікації, але й мають значний економічний вплив на розвиток ресторанного бізнесу і туризму, що робить їх важливими учасниками сучасного ринкового середовища.

Published: November 2024

Digital literacy is vital for pupils, especially the inclusion of individuals who are physically challenged. Students with impairments encounter greater barriers in obtaining the skills essential to success. This study analyzes the disability digital gap, success factors for obtaining digital skills, and consequences of a digital literacy curriculum established for special education classes in Edo North, Edo State, Nigeria. The study utilized a survey research design. Data for this research were acquired from both primary and secondary sources. This helped the researchers better comprehend the opinions of all the potential responders. The respondents were randomly recruited from the two centers and their neighborhoods. The population of this study included 200 participants, consisting of physically challenged/special children from each of the study areas, teachers who instructed the physically challenged students from each of the study areas, parents of the physically challenged students from each of the study areas and community people from each of the study areas at Auchi and Afuze Physical Challenge School Centers in Edo North. The findings from this research demonstrate that digital technologies allow physically challenged children a platform to increase their confidence, express themselves and communicate with others and that digital storytelling platforms give them a method of expressing their opinions.
Foreign exchange market and crude oil market-volatility spillover analysis
Authors: Umoru David , Ogbeifun Kelvin , Igbinovia Beauty
Published: November 2024

The reality that governs financial markets in recent times is that fluctuations in one market could rub off the volatility of another market either by moving in the same direction as the mirrored market moving in the opposite direction. Hence, researchers have often proposed that volatility transmission be considered in volatility studies in financial markets. This study sought to determine the rates of volatility spillover and shocks between oil prices and exchange rates in oil production. Data for the study were measured quarterly. The quantile regression and asymmetric GARCH estimations formed analytical tools for the study in addition to regular descriptive, unit root and cointegration tests. We find that increased spillover syndrome in the crude oil market in past periods resulted in inverse adjustments of present volatility in crude oil markets with a magnitude of 0.1339. Whereas the spillover effect from the currency market to the oil market is weaker than its effect from the oil market to the currency market is, significant incidences of asymmetric volatility are found. The significant and inverse spillover of volatility from the currency market to the crude oil market reveals that oil-producing countries utilize the crude oil market as safe-haven securities, particularly during periods plagued with economic uncertainty. Leverage effects were significantly present in the oil-exporting countries researched. The presence of leverage effects is a reflection of the heightened sensitivity of the currencies of oil-producing countries to negative shocks, particularly those related to fluctuations in oil prices. These effects can result in increased exchange rate volatility and have implications for economic stability, policy formulation, and the need for diversification efforts. Managing exchange rate volatility and stabilizing oil prices in oil exporting jurisdictions requires a combination of sound economic policies, coordinated policy responses, effective risk management, and strategies to reduce dependency on oil exports.
The expression of human relations and subcultural reflections in Neil Simon’s plays in the context of Jewish-American literature of the second half of 20th century
Authors: Nersesyan Ani
Published: November 2024

This article is related to the topic of human studies and literary discourse as well as the problems of historical memory, politics, search of identity. The research is mainly focused on the interrelation of personal and family issues in the literary heritage of Jewish-American writer Neil Simon and his specific approach in his writing style.The main approach is that problems of identity and self- estimation are based on the historical development of the USA which is commonly known as the “history of emigrants”. Thus, this history combines dual identity which is reflected in Neil Simon’s plays.Accordingly, Neil Simon develops a style, where we may notice the influence of his family, Jewish history, and Jewish-American culture. Humor was the main tool for his characters to get through this life. Simon uses satire to illustrate problems his heroes face from an ironic perspective.  Being a Jewish who lived in the USA, some of Simon’s characters are also Jews who are in search of a better life in another country. That creates a methodological basis and an opportunity for a deeper understanding and interpretation of the work of one of the brightest representatives of modern literature.

Game-based learning (GBL) is a new teaching approach that is gaining popularity in higher education. This research aims to explore the impact of using a web-based tool to teach English vocabulary and grammar skills to English as a second language (ESL) learners, with a specific focus on assessing its impacts on motivation and academic performance. Fifty (17–19 years old) undergraduate engineering students from a private university in Chennai, India, enrolled in an English grammar and vocabulary development course, participated in the study; 25 were assigned to the control group, and the remaining 25 were assigned to the experimental group. Using a mixed-methods research design, pre-and postintervention tests were conducted, and the data were analyzed via SPSS. The findings revealed that the use of a Baamboozle game-based intervention significantly improved academic performance, especially vocabulary and grammar. Student perceptions and interviews highlighted the role of customized game-based instruction in enhancing motivation, engagement, and positive attitudes, which aligns with previous research.

Authors: Deng Wenqiang
Published: November 2024

Reading comprehension is crucial for language acquisition and has garnered significant attention. In light of this, substantial research has examined the variables affecting reading comprehension from various perspectives. Studies in cognitive psychology have explored the connection between working memory (WM) and English reading comprehension. However, few reviews specifically address the influence of WM on reading comprehension in the context of Chinese English as a Foreign Language (EFL) learners. Therefore, this study aims to review the role of WM in reading comprehension among Chinese EFL learners, with a focus on how WM contributes to improved reading performance. Eight studies published between 2018 and 2023 were selected from the databases Google Scholar and Web of Science. Findings reveal a positive correlation between WM and reading comprehension among Chinese EFL learners. Moreover, WM capacity (WMC) was shown to be a significant predictor of reading performance. The results indicate that both educators and students can collaborate to strengthen WMC, thus improving reading comprehension outcomes. This review encourages further research on the impact of different WM subcomponents on EFL reading comprehension in China and on effective strategies that instructors and learners can employ to enhance WMC in the EFL learning process.

Published: November 2024

In recent years, single motion target detection, positioning, and tracking technology has been widely applied in fields such as national defense, military, traffic monitoring vehicle positioning, and drone target tracking. In response to the difficulty of detecting and locating abnormal spatial distribution of multiple targets in complex background environment conditions, in order to meet the demand for real-time and accurate localization of multiple targets, a dual station camera is used to capture multiple target image sequences. Based on target detection and multi-target tracking technology, combined with epipolar geometric matching algorithms, precise localization of multiple targets in complex environments is achieved. According to the overall experimental process, a multi-objective simulation experiment was designed. Through four levels of processing, including image acquisition, target detection, target matching, and analysis of target spatial positioning errors, the cumulative error of each algorithm in the testing system was verified to be within the allowable range of system accuracy, meeting the requirements of the testing system indicators.
