Authors: Riaz Farhad Muhammad , Khan Junaid Ali
Published: February 2025

The purpose of the current study is to present the numerical treatment of a nonlinear mathematical SEIR model based on the Zika virus using the Mexican Hat Wavelet-based feed-forward artificial neural network (MHW-ANN) together with the optimization scheme of global search, Particle Swarm Optimization (PSO) and local search Sequential Quadratic Programming (SQP), i.e. MHW-ANN-PSO-SQP. The Zika virus is an epidemic disease that can spread through the transmission of the virus known as Aedes, its model is based on susceptible-exposed-infected-recovered, i.e. SEIR that investigated the dynamics of virus spread. To solve the model an error-based fitness function is optimized through a hybrid computing scheme of MHW-ANN-PSO-SQP. To validate the precision, accuracy, stability, reliability, and computational complexity of the designed framework various cases have been taken for the virus. The results obtained from the MHW-ANN-PSO-SQP are compared to the well-known RK numerical solver and ANN-based (GA-ASA) to confirm the accuracy. At the same time, the absolute error validated the precision of the designed scheme. Additionally, the statistical analysis through different statistical operators is performed to validate the stability, convergence, and reliability of the MHW-ANN-PSO-SQP. Furthermore, the complexity of the presented scheme is analyzed through the Mean Execution Time (MET).

Bali has favorable conditions for the production and expansion of citrus plantations. However, citrus cultivation in Bali often faces challenges, including reduced yield caused by pest infestations and pathogenic diseases. One significant pest affecting citrus plants is the whitefly. A potential method for controlling whiteflies is the use of natural enemies. The entomopathogenic fungus Aschersonia placenta is one of natural enemy that can effectively manage whitefly infestations. However, the succesful utilization of A. placenta requires a specialized approach, particularly in selecting an appropriate growth medium. This study aimed to investigate the impact of different growth media on the development of the entomopathogenic fungus A. placenta. The research began with field sampling, followed by the isolation and morphological identification of A. placenta to obtain a pure culture. Subsequently, media tests were conducted to evaluate fungal growth. Nine treatments were implemented to examine the impact of different media: (1) Water Agar (WA), (2) Potato Dextrose Agar (PDA), (3) Potato Sucrose Agar (PSA), (4) Water Agar + Weaver Ant Eggs Flour (WA-WAEF), (5) Potato Dextrose Agar + Weaver Ant Eggs Flour (PDA -WAEF), (6) Potato Sucrose Agar + Weaver Ant Eggs Flour (PSA-WAEF), (7) Water Agar + Cricket Flour (WA-CF), (8) Potato Dextrose Agar + Cricket Flour (PDA-CF), and (9) Potato Sucrose Agar + Cricket Flour (PSA-CF). The results demonstrated that incorporating cricket insect flour (Gryllidae: Orthoptera) or weaver ant egg flour (Oecophylla smaragdina) into potato sucrose media provided the most optimal growth environment for A. placenta.

Environmental and climate change education in Romania from the perspective of international and national strategies in the field. On any society’s way towards sustainable development education plays a fundamental role, by providing knowledge and shaping attitudes. Over the last decades, the education for sustainable development has been increasingly addressed by specific policies at different levels – international, European, national. In this context, this paper aims to briefly review strategies/programs/plans regarding the education for sustainable development at all these levels, with a focus on those in Romania. In order to do this, we surveyed the websites of the UN, the EU, the Ministry of Education and Research of Romania, and read the representative documents on the subject, with the aim of situating developments in the field in Romania in a more general framework, and identifying specific national elements. If internationally, concerns and policies in this field are well-established, in Romania they only date back to the year 2018, as a response to the UN’s 2030 Agenda for Sustainable Development, culminating in 2022 in the development of a strategy for environmental and climate change education. As a way to implement this strategy, the “Green Week” program was introduced in all primary and secondary schools in the country.

The large number of antiseptic products on the market provide choices for people to choose alcoholic or non-alcoholic hand sanitizers. Most commercial hand sanitizers are 70% to 90% alcohol-based. For some people, the use of alcohol-based hand sanitizers is not friendly for sensitive skin. Therefore, in this study efforts were made to minimize the use of alcohol as an antiseptic agent in hand sanitizers by using lime peel extract and betel leaf extract. Betel leaves contain chemicals that are useful as antiseptic, antibacterial, and antioxidant substances. The lime peel contains flavonoid compounds that are useful as antioxidants, antiseptics, anticancer, anti-inflammatory, and antibacterial. The results showed that the extraction of lime peel was dark brown and betel leaves were blackish brown. Lime peel extraction was carried out for 5 hours using the maceration method while lime peel extraction used the reflux method. The results of the inhibition test using the Disk Diffusion Test method showed that the growth of bacteria in the sample area grew less compared to the eco-enzyme and water. While the results of the organoleptic test showed that bio-hand sanitizer products made from the lime peel and betel leaf were quite attractive to respondents.

Verbal Representation of Cultural-Historical Memory in Graffiti Discourse
Authors: Shalkov D. Yu. , Bylkova S. V.
Published: February 2025

This article explores various methods of verbal representation of cultural-historical memory within graffiti discourse. Street art objects are presented as a sociocultural discursive formation that conveys specific national concepts, spiritual and moral guidelines, and ethical principles. The aim of this study is to examine the types of precedent phenomena utilized by graffiti writers and to propose a classification of the corresponding verbal street art objects based on the findings. The material analyzed comprises over 200 graffiti pieces featuring diverse intertextual inclusions. The minimal structural-semantic unit of a precedent phenomenon is identified as the intertexteme — linguistic means that realize intertextual connections within specific textual contexts. The authors conclude that intertextemes based on historical and cultural material of varying quality serve to reveal the communicative-pragmatic intentions and worldview objectives of graffiti writers. By infusing urban spaces with unique meanings, graphic street art objects not only highlight pressing socio-economic issues but also contain philosophical reflections and include content that facilitates the effective transmission and preservation of the national cultural-historical code.
Mollusk or Triton? Poetic Imagery of Joseph Brodsky’s “Great Poem”
Authors: Bogdanova O. V. , Baranova T. N.
Published: February 2025

This article presents a new interpretation of Joseph Brodsky’s “Great Poem” titled “Triton” (1994, originally named “Mollusk”) and its titular imagery. It is noted that previous scholars have exclusively interpreted the titular image metaphorically, relying on the poem’s poetic imagery and allusively linking the mollusk and triton images to the symbolism of the marine element or, more concretely, to the historical and architectural context of the poem. This study adopts a different approach, suggesting a connection between the poem’s creation and real events in Brodsky’s life, particularly a heart attack he experienced shortly before writing. It demonstrates that the image of the mollusk has a specific source of metaphorization in Brodsky’s work — the human heart, which, like a living mollusk, opens and closes its valves, filling its chambers, and is intricately linked to the vital aorta. The article traces how seemingly incidental “medical” details accumulate additional connotations, providing semantic and meaningful support for the entire poetic structure. Various reasons and origins for the change in the poem’s title and the transformation of its titular imagery are proposed. It is shown that the “mystery” of the titular image in Brodsky’s poem possesses both existential and quotidian dimensions. The authors note that the context of Soviet literature in which the poet was formed did not hinder him from creating a profound philosophical work.
State and Islamic Holidays in Kabardino-Balkaria: Past and Present
Authors: Tatarov A. A.
Published: February 2025

This article presents a historical analysis of the Russian government’s policies regarding Islamic holidays over the past century, focusing on the case of Kabardino-Balkaria. Drawing on archival and published data, the author highlights the influence of historical legacies established during the Soviet era. It is noted that in the 1920s, Islamic holidays in Kabardino-Balkaria were officially recognized as non-working days for the first time. The study pays particular attention to the activities of the Council for Religious Affairs and the Council for Religious Cults during the 1940s to 1980s. Utilizing reporting documents, it introduces data on governmental tactics, as well as information regarding the number of participants, venues, and the gender composition of Muslims who observed fasting and engaged in communal celebrations. The article argues that for Muslims in Soviet Kabardino-Balkaria, the holidays of Uraza-Bayram and Kurban-Bayram became institutions for preserving religious practices amidst stringent secularism. Additionally, it examines the period of Islamic revival in the post-Soviet era, during which these holidays regained their status as regional non-working days. The findings demonstrate that government authorities and local self-governance bodies, along with political actors, actively participate in organizing these celebrations within the framework of identity politics and the regulation of public events.

Published: February 2025

Zinc oxide (ZnO) hollow spheres are gaining attention due to their exceptional properties and potential applications in various fields. This study investigates the impact of different zinc precursors Zinc Chloride (ZnCl2), Zinc Nitrate [Zn(NO3)2], and Zinc Acetate [Zn(CH3COO)2] on the hydrothermal synthesis of ZnO hollow spheres. A comprehensive set of characterization techniques, including Field Emission Scanning Electron Microscopy (FE-SEM), X-ray Diffraction (XRD), Thermogravimetric analysis (TGA), and Brunauer-Emmett-Teller (BET) analysis, was utilized to assess the structural and morphological features of the synthesized materials. Our findings demonstrate that all samples exhibit a high degree of crystallinity with a wurtzite structure, and crystallite sizes range between 34 to 91 nm. Among the different precursors, ZnO derived from Zinc Nitrate showed markedly higher porosity and a well-defined mesoporous structure than those obtained from Zinc Acetate and Zinc Chloride. This research underscores the significance of precursor selection in optimizing the properties of ZnO hollow spheres, ultimately contributing to advancements in the design and application of ZnO-based nanomaterials.

Published: February 2025

This study presents a comprehensive two-dimensional numerical analysis of natural laminar convection within a square cavity containing two circular heat sources, which simulate electric cables generating heat due to Joule heating. This scenario is particularly relevant in aeronautics, where excessive heating of electrical installations can lead to significant material and human safety risks. The primary objective of this research is to identify the optimal spacing between the two heat sources to mitigate the risk of overheating and ensure the safe operation of the electrical installation. To achieve this, various configurations were analyzed by adjusting the distance between the heat sources while also varying the Rayleigh number across a range from 103 to 106. The governing equations for the fluid flow and heat transfer were solved using a FORTRAN-based numerical code employing the finite volume method. The results indicate that the heat transfer characteristics within the cavity are significantly influenced by both the distance between the heat sources and the Rayleigh number. The analysis revealed that the average Nusselt number (Nuavg) peaked at a value of 14.69 when the distance between the heat sources was set at 0.7 units and the Rayleigh number was at 106. This finding suggests that maintaining this specific spacing between the electrical cables can optimize heat dissipation and enhance the safety of the installation. In conclusion, the study recommends adopting a spacing of 0.7 units between the electrical cables to ensure optimal thermal performance and minimize the risk of overheating, thereby safeguarding both the materials and personnel involved in aeronautical operations.

Published: February 2025

Viral hemorrhagic septicemia (VHS), Infectious hematopoietic necrosis (IHN), and Koi herpesvirus disease (KHVD) are listed diseases by the European Commission that pose significant threats to the global aquaculture industry, resulting in substantial economic losses and impacting fish health and welfare. Due to their rapid spread potential, it is crucial for member states to implement measures preventing their transmission to disease-free areas. In this study, we aimed to assess the presence or absence of these viruses in fish aquaculture facilities in North Macedonia. During 9 years of surveillance from 2015 to 2023, 1,527 samples were tested for VHS and IHN, and 2,760 samples were tested for KHVD from aquaculture sites across North Macedonia using molecular diagnostic techniques. Our results indicated the absence of VHS and KHVD in all tested samples. However, the number of IHN-affected farms increased from two in 2018 to 33 by 2023, persisting across multiple sites. Despite the absence of VHS and KHVD, the ongoing presence and increasing incidence of IHN highlight the need to assess the effectiveness of existing biosecurity measures and disease management practices in the region. Ongoing surveillance and stringent biosecurity measures are essential for controlling IHN and preventing the introduction of other viral pathogens. Strengthening these measures is vital to ensure the long-term sustainability of the aquaculture industry in North Macedonia.

Published: February 2025

Given that researchers aim to publish in prestigious journals, understanding the rhetorical organization of such publications is crucial.  While this topic has been extensively studied, existing research has yet to explore how authors in reputable journals engage with prior literature. To fill this gap, the present study intends to analyze how research article authors respond to other earlier literature in their research article introductions (RAIs) published in reputable international applied linguistics journals. This study aims to achieve two objectives: to find out to what extent responding to other earlier literature is important in RAIs, and to discover what types of response authors employ in their RAIs. To achieve these goals, this study employed combined descriptive qualitative and quantitative approaches for analyzing 40 RAIs published in Q1 journals as data sets in the present study. Then, a new analytical framework was designed to respond to the above objectives. The results indicated that responding to other earlier literature is obligatory in RAIs published in reputable international applied linguistics journals. In responding to other earlier literature, authors employed three types of response: either extending other earlier studies, modifying other earlier studies, or establishing a new method, idea, or knowledge. This study offers theoretical contributions by expanding the understanding of how research article authors engage with prior literature within their RAIs.  Its practical implications include guiding researchers on effectively utilizing prior literature to establish their research agenda when publishing in reputable journals.
Attitudes toward language and language choice in regional intermarriage families: A case study in Tangerang, Banten
Authors: Indarti Dwi , Manara Christine
Published: February 2025

Despite extensive research on language attitudes and shifts in Indonesia, studies on language choice in intercultural marriages remain scarce. Therefore, this study explores the attitudes toward heritage, national and international languages, as well as factors influencing language choice in regional intermarriage families living in Tangerang, Banten. This research employed a qualitative case study and used a purposive sampling technique to select the respondents. The respondents were four mothers whose spouses come from different regional cultural backgrounds and live in the Tangerang area. Using questionnaires and semi-structured interviews, this study revealed positive attitudes toward heritage, national, and international languages among respondents, emphasizing the significance of regional languages as crucial elements in maintaining connections with their cultural roots and fostering a sense of self-awareness and appreciation of their cultural backgrounds. However, discrepancies emerge between the parents’ beliefs and their actual efforts to maintain and preserve the heritage language for their children. Meanwhile, well-educated female parents perceive mastering English as essential in a globalized world. They prioritize English proficiency to provide educational opportunities for their children. This dual perspective on language reflects an attitude among the respondents that is sensitive to levels of formality and covers diverse purposes of language. On one hand, the desire to learn and use English to connect with the global community indicates an awareness of the importance of a global language for communication, education, and opportunities beyond their local context. On the other hand, their attachment to national and regional languages highlights a strong sense of cultural identity.

The goal of this study was to determine how diversified intelligence (DI) can predict various aspects of L2 writing. To achieve this, 120 intermediate English as a Foreign Language students were selected using the Oxford Quick Placement Test (OQPT). The learners were given Abdulaal, Alenazi et al.’s (2022) DI questionnaire. The participants were asked to prepare an argumentative essay in sixty minutes on a given subject. Each writing component—tenor, organization, coherence, vocabulary, grammar, spelling, and pronunciation—was considered when assigning a score to the students’ writings. The inter-rater reliability, as determined by Pearson’s correlation, was 0.87. The data were analyzed using multivariate regression in AMOS (Version 22) to answer the following basic research question: Which types of DIs contributed to various characteristics of L2 writing? The findings demonstrate how diversified intelligence impacted different aspects of learners’ writing. It was discovered that intrapersonal, musical, and naturalistic intelligence significantly impacted the grammar of EFL students’ writings; kinesthetic, existential, logical, and naturalistic intelligence had an impact on the punctuation components of L2 writings; verbal, kinesthetic, and naturalist intelligence had influences on students’ writing organization; visual, interpersonal, logical, and existential intelligence played a significant role in the students’ cohesion; and finally, logical, and existential intelligence significantly impacted the relevance and sufficiency of the thematic tenor.

Published: February 2025

As the 21st century progresses, there is a growing emphasis on equipping students with essential skills, including writing, which is considered crucial to master. Online writing has become particularly significant in fostering this skill, as advanced technology enhances classroom activities and creates new opportunities for interaction between lecturers and students. This study aimed to assess the levels of six types of interaction, identify the forms of interaction students value most, determine the forms most frequently conducted by lecturers, and explore the benefits of these interactions in an online writing course. This study utilized a sequential explanatory design involving 122 respondents. Data were collected using two research instruments: a questionnaire and interviews. The findings revealed that respondents demonstrated two preferences for a high level of interaction, both of which showed a notable increase in the six forms of interaction. Among these, four types of interaction were perceived by students as playing a critical role in their online writing activities. However, only three forms of interaction were identified as being frequently implemented by the lecturer, reflecting an emphasis on student-centred learning. Each type of interaction was acknowledged as contributing distinct benefits to the students. This study underlines the importance of adopting diverse and student-centred interactions in online writing courses to enhance student engagement and learning outcomes.

Published: February 2025

The present study explores two primary social psychological factors—motivation and attitudes—towards learning the English language across various educational levels following the 2011 revolution in Tunisia. Utilizing a mixed-method research approach, this study combined quantitative and qualitative data collection methods to gain comprehensive insights. An arbitrary sample of 170 students, from primary to secondary education and university levels, was surveyed using the Attitude/Motivation Test Battery. Additionally, semi-structured interviews were conducted with 9 students and 3 directors from three educational institutions. The study encompassed six key domains: (1) attitudes regarding English language learning, (2) motivation, (3) integrative motivation, (4) instrumental motivation, (5) parental involvement, and (6) attitudes towards language policies. The results indicate that students exhibited positive attitudes and high motivation toward learning English. Furthermore, the data revealed a positive orientation toward learning the English language in terms of integrative and instrumental motivation. Notably, instrumental motives were identified as the primary basis for students’ motivation to learn English, slightly surpassing their integrative motivation. Moreover, a significant and positive correlation between attitude and motivation was observed. Conversely, the findings unveiled that all interviewees perceived educational policies as detrimental to English language learning. Their collective feedback underscored persistent challenges associated with English language education in school environments and society. Ultimately, all participants, either directly or indirectly, advocated for a heightened emphasis on the importance of English and called for a revision of language policies.

Authors: Gunawan Wawan , Humaira Silmy Arizatul , Hardini Tri Indri , Zifana Mahardhika
Published: February 2025

Attention has been given to multimodal texts to investigate their potential meaning affordances that facilitate learning and raise awareness of ideological meanings. However, how learners learn to make meaning by integrating intermodal relations involving language and visual images, especially in the context of learning English as a foreign language (EFL), has not been researched much. This study investigated the emerging process of meaning-making in digital factual storytelling practices in a senior high school in Indonesia. Fifty-six students participated in this study and each produced a digital storytelling video (DST). The DST videos were analyzed using an intersemiotic complementary framework to reveal the occurrences and typical intermodal meaning-making practices, as shown in the student digital storytelling (DST) videos on autobiography. The analysis focused on describing the emerging modes of making experiential meanings of the intermodal verbal-visual relations. It was found that the process of meaning-making was dominantly constructed in an exposition manner involving the verbs within clauses for identifying and describing. The emerging meanings resulting from the multimodal affordances allow storytellers to track with the potential meanings projected by the images. The selection of digital images helps students explore words when telling a story, shifting the conventional genre of autobiography. This study indicates the need to emphasize the purpose of text and to afford multimodal features to support the achievement of communication purposes.

Authors: Qassrawi Rania , Al Karasneh Samih Mahmoud
Published: February 2025

The widespread use of Artificial intelligence (AI) in language education has opened up a new era of teaching and learning, raising concerns about balancing AI-driven instruction and conventional teaching methods to achieve optimal learning outcomes while preserving essential human skills. Hence, this meta-analysis study systematically presented the findings from 60 studies conducted between 2018 and 2024, exploring the role of AI applications in language teaching. We investigated language skills and domains that AI can enhance, including skills (i.e., listening, speaking, reading, and writing), translation and interpretation, and teaching pedagogy and methods, alongside the human-centric skills that AI cannot replicate in language education. Based on the findings, AI could make significant strides in improving language proficiency, particularly in areas such as pronunciation, conversational fluency, grammar, and vocabulary. It can also assist in streamlining teaching methods, such as adaptive learning, automated assessment, and personalized content creation. However, some limitations emerged from the data. While AI excels at providing objective feedback and supporting innovative teaching methods, it struggles to cultivate essential human skills like cultural sensitivity, emotional intelligence, and critical thinking. These skills are necessary for effective communication, building relationships, and understanding language tones in different contexts. The study concluded that AI can be a powerful tool for language education but cannot replace human educators. Instead, language teaching practices should bridge a balance between AI-powered instruction and traditional teaching methods, so learners can benefit from the latest technological advancements while still developing the critical human skills they need in this ever-changing world.
World Modelling Potential of Autobiographical Discursive Practices
Authors:   Tomsk State University, Voloshina S.
Published: February 2025

The article is devoted to the description of the world-mode­ling potential of official autobiographical practices through an appeal to the concept of FAMILY. The research material consists of 320 office autobiographies, which are stored in the archives of the Tomsk region. The method of discursive analysis in combi­nation with the methods of conceptual and comparative analysis is used. The linguistic means of objectification of the FAMILY concept are revealed. Examples of information that the authors of autobiographies indicated or, on the contrary, concealed about their family, depending on socio-historical conditions, are given. It is shown that autobiographical practices are one of the tools for modeling the world and demonstrating a person’s personal value system. The specifics of the implementation of the concept in the texts are determined against the oral autobiographies re­corded on the territory of the Tomsk region from 1946 to 2023. The concept of FAMILY implemented in autobiographical prac­tices reflects not only the specifics of an individual’s life, their system of values, but also the features of the era in which the authors of the texts live, and the system of values of individual generations. Thus, it is shown that autobiographical practices act as а tool for modeling the world.

Published: February 2025

The lifting of PPKM (Implementation of Restrictions on Community Activities) is a policy by the Indonesian government to combat Covid-19 which potentially contains information that could influence stock prices. This study aims to analyze market reactions by examining whether there are abnormal returns on the announcement of the lifting of PPKM on December 30, 2022, with a focus on IDX30 issuers during the period from August 2022 to February 2023. The method used is an event study with an event window period of 11 days, consisting of 5 days before (pre-event), the event date, and 5 days after (post-event) the announcement. To calculate the expected return, the market model is used, and the hypothesis is tested with a one-sample t-test. The results show that significant abnormal returns only occur in the period -3, while the other periods did not show any significant abnormal returns. The results of this research indicate that the announcement of the lifting of PPKM is not strong enough to influence the market, which shows the condition of the capital market in the form of semi-strong efficiency.

Authors: Alienta Angelin , Tanujaya Kennardi
Published: February 2025

This study is motivated by the high incidence of delayed audit report submissions among property sector companies listed on the Indonesia Stock Exchange, which hinders stakeholder decision-making. The aim of this research is to analyze the factors influencing these delays, such as the impact of COVID-19, the role of internal audit, board independence, board size, and board meeting frequency. The study employs a quantitative approach using secondary data from the financial statements and annual reports of 47 companies from 2018 to 2022, analyzed through Moderated Regression Analysis. The results reveal that COVID-19 has a significant positive relationship with audit report delays, while the internal audit function has a significant negative relationship. The variables of board independence, board size, and board meetings, as well as the moderating effect of ownership concentration, are found to be insignificant. The findings emphasize the importance of internal audits in expediting audit reporting. The implications of this study suggest that companies need to strengthen internal audit functions and improve governance practices to reduce delays.

Introduction: Abdominal circumference serves as an indicator in determining central obesity criteria. In the Asia-Pacific region, the central obesity criteria are abdominal circumference ?90 cm for men and ?80 cm for women. Menopausal women experience decreased estrogen levels associated with the loss of subcutaneous fat and increased abdominal fat. When there is excessive fat distribution in the central body, there is a possibility of decreased adiponectin levels as an anti-atherogenic factor, leading to increased blood pressure. This study aims to determine the relationship between abdominal circumference and blood pressure increase in menopausal women in the Mengwi District.
Method: A cross-sectional study was conducted on a population of menopausal women aged 45-55 years using a consecutive sampling technique. Subjects were selected according to inclusion, exclusion, and dropout criteria until the total number of subjects reached 85 individuals. Data analysis was performed using the Spearman rho test to determine the relationship between variables and the correlation strength.
Results: Based on the data analysis, there was a significant relationship between abdominal circumference and blood pressure, as evidenced by a p-value of 0.018 (p<0.05) and a weak positive correlation coefficient (0.255).
Conclusion: Abdominal circumference is associated with increased blood pressure in menopausal women with a weak correlation level.
