Abstract
Let (M, f, g) be an (m, n)-hypermodule over an (m, n)-hyperring (R, h, k). A proper subhypermodule N of M is called n-ary 2-absorbing subhypermodule if whenever g(r

(n−2)) ⊆ N for some i ∈ {1, . . ., n − 1}. Various properties of n-ary 2-absorbing subhy-permodules are investigated. In particular, it is shown that if N is a subhypermodule of an (m, n)-hypermodule (M, f, g) over an (m, n)- hyperring (R, h, k), then N is n-ary 2-absorbing if and only if whenever g(I

Authors: Li R. , Onasanya B. O. , Yusuff S. O. , Feng Y. 
Published: February 2025

Abstract
In this paper, some properties of a BPFR were studied. Also, level sets of BPFRs were studied with their properties. Some results were given and, in some cases, examples and counter-examples were constructed. In particular, we have shown that if a BPFR Q is a subset of another BPFR ρ, (s, t)-level (or strong level) subsets of Q are classical subsets of the (s, t)-level (or strong level) subsets of ρ and that the strong level subsets of a BPFR is a subset of the ordinary level subset of the same among others. By these, we have improved on some of the results in the previous work and have laid the right foundation for further works on these concepts.

S
Authors: Yildirim Tulay 
Published: February 2025

Abstract
In this study, we focus on skew cyclic codes over the family of rings 𝔽q S where q is a power of a prime number and S = 𝔽q + v𝔽q with v
2 = v. Structural properties of these codes are studied in detail. Obtained results lead us to characterize 𝔽q S-linear skew cyclic codes. All the minimal spanning sets and generators of these codes are presented. Furthermore, some good 𝔽q -linear codes are obtained as images of the 𝔽q S-linear skew cyclic codes under the Gray mapping.
Approximate solution for a malaria model using the homotopy analysis method
Authors: Duru Emmanuel Chidiebere , Mbah Godwin C.E. 
Published: February 2025

Summary
Malaria as an infectious disease is caused by the Plasmodium parasite, and transmitted amongst humans through the bites of the female Anopheles mosquito. In this work, we used a system of nonlinear ordinary differential equations to present a new model for the disease. The model incorporated vaccination, treatment and vector control using sterile-insect technology. Sensitivity analysis was performed to identify the parameters which affect the endemicity of the disease. The approximate solutions of the system were obtained using the homotopy analysis method. The results obtained showed the region of convergence for the solutions. Plots were used to show this convergence region, highlighting the advantage of HAM over many other approximation methods. MATLAB and Maple were used in the simulation and mathematical analysis.
Filtering theory for an Ornstein-Uhlenbeck process driven power system dynamics
Authors: Hirpara Ravish H. 
Published: February 2025

Abstract
This paper revisits the non-Markovian state vector of an Ornstein-Uhlenbeck process-driven power system dynamics in non-linear filtering framework. The Fokker-Planck setting accounts for the process noise correction term and ignores the observation noise correction term in the analysis of stochastic systems. This paper introduces the notion of the ‘Kushner-Stratonovich setting’, which accounts for the process noise as well as observation noise correction terms in the conditional moment evolution equation. The Kushner-Stratonovich setting is the cornerstone formalism of nonlinear filtering problems of stochastic control systems. We wish to estimate the rotor angle from given observations using two non-linear filters: (i) a Gaussian non-linear filter, and (ii) the extended Kalman filter. This paper develops two non-linear filters for a filtering model for the machine rotor angle, in which the Ornstein-Uhlenbeck process is the process noise and the Brownian noise process is the observation noise. The filter efficacy is examined by utilizing quite extensive numerical experimentations with two sets of data.
Barriers and Drivers by Sustainability School Community Projects Implementation: What Changes Appeared
Authors: Janoušková Svatava , Bílek Martin , Boesen Jesper 
Published: February 2025

Abstract
School-community projects have become essential components of educational systems worldwide, aiming to engage students and local communities in collaborative initiatives. This article explores the implementation of school community projects, focusing on sustainability themes, by addressing two research questions: RQ1 examines the current knowledge about barriers and drivers in school-community projects, and RQ2 investigates how these factors have evolved in response to critical societal changes. Experts’ perspectives on open schooling projects conducted in 2022 and 2023 were collected using retrospective think-aloud interviews. The study adhered to ethical principles, ensuring participant anonymity and consent. The findings reaffirm previously identified barriers and drivers, such as the significance of leadership commitment, effective communication, and student engagement. However, our research unveils novel insights, highlighting the challenges posed by declining student well-being, eco-anxiety, and diminished interest in projects, notably among older students. Puberty, environmental grief, and post-pandemic effects are identified as contributing factors. Teachers emphasise the importance of hands-on activities within project curricula to mitigate these challenges, bridging the gap between theory and application. Collaborative decision-making and planning also play a crucial role, with difficulties arising from perceiving sustainability projects as solely science-oriented. Furthermore, our study suggests that while long-term partnerships with external stakeholders are valuable, it is essential to limit the frequency of projects to prevent burnout among participants. In conclusion, our findings underscore the need for a holistic approach to project design, including mental health considerations and interdisciplinary collaboration, to maximise the positive impact of such initiatives in an ever-changing educational landscape.
Environmental Awareness of the Personnel of the Slovenian Armed Forces: Self-Identification as a Basis for Strengthening the Environmental Aspect of Civil-Military Relations
Authors: Grčar Silvo , Sotlar Andrej , Eman Katja 
Published: February 2025

Abstract
Military activities have a certain impact on the environment and are therefore regulated by national legislation and internal regulations. Strategic and development documents from the field of defense include aspects of environmental protection, sustainable use and energy efficiency. The modernization of the Slovenian Armed Forces and investments in sustainable technology present new opportunities and bring some risks. Among members of the Slovenian Armed Forces, a high level of environmental awareness is expressed, although depending on the status of the members, there are differences in attitudes about the impact of military activities on the environment. The environmental aspect of civil-military relations in the Republic of Slovenia is of strategic importance in order for the Slovenian Armed Forces to maintain its reputation as a credible and environmentally responsible institution and more comprehensively fulfill its functional imperative in the long term.

Authors: Kogoj Mark 
Published: February 2025

Abstract
The paper examines the strategic culture and the U.S. engagement in the Russia-Ukraine conflict between February 2014 and September 2024. It identifies and examines traditional elements of American strategic culture, such as the idea of American exceptionalism, the liberal philosophical tradition, internationalist foreign policy, the role of NATO and the strategy of indirect engagement, the role of public opinion and the influence of the Protestant ethic, and technical fetishism. Traditional elements of American strategic culture are reflected in and explain US behavior in the Russia-Ukraine conflict. The US behavior in the Russia-Ukraine conflict confirm the pattern of continuity within the US strategic culture.
Analysis of the Actors of the Ukrainian-Russian War: After Two and a Half Years (February 2022-July 2024)
Authors: Červek Luka Ružičič 
Published: February 2025

Abstract
The Russo-Ukrainian War was the first major conflict in Europe since the Balkan Wars. The conflict has been ongoing since 2014 with the annexation of Crimea. Russia expected a quick and easy victory and the subjugation of Ukraine in its February 2022 attack. Russian forces encountered fierce resistance from the Ukrainian army and civilian population. Russian troops were forced to reorganise and focus on the southeastern part of Ukraine. The aggression was met with a solid international response and condemnation, and many countries imposed sanctions against Russia. Western countries, led by the USA and the EU, supported Ukraine with extensive humanitarian and military assistance. The article analyses the conflict using the Birmingham method and focuses on the key actors. The conclusion summarises the analysis of the possibility of ending the conflict and provides strategic reflection.
Examining The Time Prisoners Study Using E-Learning While In Prison: Sustainability of E-Learning Programs in Prison
Authors: Mahlangu Vimbi Petrus 
Published: February 2025

Abstract
This study investigates the amount of time that convicts dedicate to studying through e-learning while in jail, with the goal of comprehending their drive despite difficult living conditions. The qualitative research was carried out at a jail in Namibia, using interviews as the method of data collection, in accordance with an interpretive paradigm. Thematic analysis was conducted on verbatim transcriptions of tape-recorded interviews. Namibia’s judicial system has shifted its focus from punitive measures to prioritizing prisons and community reintegration. Prisoners exhibit a resolute commitment to furthering their education using e-learning programs, regardless of the constraints imposed by their surroundings. Through the adoption of e-learning opportunities, inmates are given the ability to overcome obstacles to education that are typically linked to being incarcerated, such as having limited access to educational resources and restricted study hours. E-learning platforms offer jailed individuals a flexible and easily accessible method of acquiring knowledge and skills, enabling them to pursue academic interests and career goals. Furthermore, the results indicate that e-learning programs have the capacity to foster optimism and a sense of direction among incarcerated individuals, providing them with a means to rehabilitate and reintegrate into society effectively after their release. Through participation in educational endeavors, jailed prisoners not only obtain academic credentials but also cultivate important life skills and competencies that are crucial for their reintegration into society.

Authors: Thamae Lipolelo , Matee Lihotetso Gloria 
Published: February 2025

Abstract
In today’s fast-changing world, it is essential to equip English as a Second Language learners with strong literacy skills, empowering them to critically assess information, adjust to technological shifts, and engage in global discussions. However, what remains questionable is the suitable pedagogical practices and the teachers’ and the learners’ roles in sustaining literacy in an education system: this study explored pedagogical practices and investigated both stakeholders’ roles in sustaining literacy among ESL learning. The study employed a mixed-methods approach, drawing on two theoretical frameworks: Legitimation Code Theory and Constructivism. Data collection involved tests, questionnaires, document analysis, focus groups, and observations, with analysis conducted using thematic (Atlas.ti), Excel and ANCOVA via Stata17 in SPSS. Results verified that employing semantic gravity and density sustain critical literacy skills. Notably, the null hypothesis (ℎ0) was rejected, confirming influence of the application of semantic gravity and density on informing critical literacy teaching practices.
Citizenship education in Lithuanian preschool education : The teachers’ view
Authors: Bražienė Nijolė , Kovienė Skaistė 
Published: February 2025

Abstract
In Lithuania, citizenship education for preschool children was not regulated until 2022, and consequently the related issues have not yet received much attention from Lithuanian researchers. However, based on the insights of scientists from other countries it can be argued that in order for children to be active citizens when they grow up, it is important to develop their civic attitudes and behaviour in early childhood. The aim of the research presented in the article is to find out teachers’ attitudes towards citizenship education for young children in Lithuanian preschool education. Summarising the results of a structured group interview, we can state that in Lithuanian preschool education institutions, children receive only a fragmentary and superficial education in citizenship, because, on the one hand, teachers have a narrow conception/understanding of citizenship and, on the other hand, they basically do not understand the content of the citizenship education programme and what components constitute citizenship competence. However, it should be noted that teachers understand the need to change the current practice, but they do not know how this can be done.

Published: February 2025

Abstract
Fully-grown mammalian oocytes contain morphologically evident but transcriptionally inactive nucleoli called “nucleolus-like bodies” (NLBs). These nuclear structures are essential for early embryonic development. Removing oocyte NLBs (enucleolation) before their activation leads to developmental failure, mainly at the time point of embryonic genome activation. The present study examined the developmental and expression dynamics of embryos derived from intra- (pig) and interspecies (mouse) nucleolus (NLB) transferred porcine oocytes after parthenogenetic activation. Activation of rDNA transcription and pre-rRNA processing in NLB re-injected embryos was observed by real-time qRT-PCR analysis, targeting the expression rates of 45S rRNA and levels of 18S rRNA. Reinjection of NLBs from mouse or porcine GV oocytes into the enucleolated MII stage porcine oocytes supported the embryonic development up to the blastocyst stage after their activation. Intra- and intergeneric NLB transferred embryos demonstrated rDNA transcription initiation at the 8-cell stage, corresponding with the embryonic genome activation in porcine parthenogenetic embryos (control). The measured levels of 18S rRNA in these experimental embryos showed delayed initiation of pre-rRNA processing at the blastocysts stage compared with the control (8-cell stage). However, the porcine embryos with re-injected mouse NLB displayed significantly higher levels of 18S rRNA than the control and experimental intraspecies group. In conclusion, NLBs from different mammal species (mouse) can enhance the quality of enucleolated porcine oocytes and thus support their early embryonic development after activation.
Transgressing the Borders of Art and Non-art: The Case of Elmerice Parts and Herman Kolt-Oginsky
Authors: Maripuu Anne-Liis 
Published: February 2025

Abstract
Modern dance made its way to Estonia in the 1910s. By putting on stage a new woman and picturing her in a new way, modern dance challenged many members of society, sometimes even being seen as disgraceful. In 1926 and 1927, Elmerice Parts (1878–1974) and Herman Kolt-Oginsky (1902–1977) created scandals with their dance numbers in Estonia. According to reviewers, the dancers transgressed the line between art and non-art. The artists were attacked for making use of acrobatic and “erotic” elements; not surprisingly, the latter aspect was seen more critically. The aim of this article is to understand where the line between art and non-art lay in the 1920s. I come to the conclusion that artfulness was associated predominantly with spirituality and the unconscious: When the dancer focused on bodily experiences and highlighted their physical body parts, it became non-art. The main source of information is articles published in print media in 1926 and 1927. I analysed the data using qualitative methods.
Evaluation of the Reliability of a Physical Activity Questionnaire Proposal for Girls Aged 8-11 with Postural Disorders
Authors: Chwalewska Wioleta , Wiernicka Marzena 
Published: February 2025

Abstract

Introduction.
Regular physical activity (PA) protects both the mental and physical health of individuals across all age groups. Documented health benefits for children include improved physical fitness and endurance, reduced risk of cardiovascular and metabolic diseases, lower likelihood of depression and obesity, enhanced bone density, improved cognitive functioning, and better posture. A review of the literature did not identify any questionnaire that had been translated and adapted to Polish conditions in order to assess PA in children aged 8-11. Therefore, a Physical Activity Questionnaire was developed. The aim of this study was to evaluate its reliability for a group of girls aged 8-11 with postural disorders.

Material and Methods.
The study group consisted of 32 female students aged 8-11 with postural disorders in the transverse plane. The Physical Activity Questionnaire includes three questions that were developed based on the PAQ-A (Physical Activity Questionnaire for Adolescents) and HBSC. The selected questions were adapted to the assessed age group. The validation of the questionnaire was conducted using the test-retest method.

Results.
The reliability of individual items in the questionnaire was assessed using the ICC/KAPPA coefficient, depending on the type of variable. It was found that most items (except for items 3.7 and 3.18) demonstrated good reliability. This also applies to the questionnaire as a whole (ICC = 0.85; p < 0.001). Sufficient repeatability across successive tests was confirmed.

Conclusions.
The Physical Activity Questionnaire is a relatively reliable tool for determining the level of physical activity in girls aged 8-11 with postural disorders.
Free Independent Travelers (FITS) Travel Preferences and Behavior: A Post-Endemic Perspective
Authors: Kamaruddin Nhajril , Amir Ahmad Fitri , Ali Quratulain Syahirah Awang , Hanafiah Mohd Hafiz 
Published: February 2025

Abstract

Introduction.
This empirical study investigates the outbound travel preferences, risk perception, and behavior of Free Independent Travelers (FITs), specifically focusing on the post-endemic perspective.

Material and Methods.
Data were collected from 345 respondents using a purposive sampling method. The data were analyzed using Partial-least Squares-Structural Equation Modeling (PLS-SEM) through SmartPLS 4.0 software.

Results.
Contrary to much existing literature, the study revealed that perceived threat and transmission risks did not negatively impact FITs’ travel intentions. Instead, both risk perceptions positively influenced travel attitudes, likely due to post-pandemic factors such as government mitigation measures and high vaccination rates. Additionally, FITs’ travel intentions were significantly influenced by their attitudes and perceived behavioral control.

Conclusions.
The study contributes to the emerging discourse on post-pandemic travel behaviors by challenging traditional assumptions about the role of risk perception in shaping travel decisions. It shows that perceived risks do not deter FITs’ travel intentions post-pandemic. Instead, these risks positively influence travel attitudes, highlighting the role of mitigation measures and vaccination rates, and offering fresh perspectives on travel behavior in a post-endemic world.
Traduzir o écart ou por que não confiar na fidelidade
Authors: Stradioto-Casolato Ana Magda , Julien François 
Published: February 2025

O filósofo, helenista e sinólogo francês François Jullien desenvolveu um método de sondar algumas das noções chaves do pensamento europeu-ocidental ao adotar uma outra perspectiva para examiná-las, a do pensamento chinês-oriental. Ele propõe uma forma de “de- e re- categorização de um conceito”, ou seja, sem ficar paralisado em nenhum destes dois pontos de vista, mas se libertando de um por meio do outro e assim permitir que se interpretem. É com este exercício que ele aborda a tradução. Ele elabora a sua reflexão sobre o tema valendo-se de certas proposições desenvolvidas e dispersas em várias de suas obras. A questão que o filósofo se coloca é: como a tradução, bem como o próprio pensamento europeu-ocidental pode ser renovado e, até mesmo modificado, ao se traduzir uma língua que não pertence à família linguística do indo-europeu, como o chinês que, além disso, é o único idioma existente atualmente cuja escrita não é fonética, mas ideográfica. Para responder a esta indagação, ele faz estremecer alguns dos constructos base do pensamento helenista que reverberam no que chama de “trabalho da tradução” como as categorias de Aristóteles e Kant, ou ainda, o Ser, Deus, a liberdade, etc. Criticando expressões que usualmente são empregadas no debate acerca da tradução, como “perda”, “traição”, “fidelidade”, “luto”, “diferença”, “equivalência”, “comparáveis”, Jullien ilustra as suas proposições com exemplos práticos de traduções do chinês para o francês e vice-versa. Ele pensa a tradução em termos de écart e entre. Écart é o fenômeno responsável pela abertura de uma distância que faz surgir o entre, o espaço onde o Outro – a língua e culturas de partida – é colocado e mantido em relação. A tradução se opera neste entre aberto pelo écart. Traduzir, segundo Jullien, é, em um primeiro momento, assimilar para, a seguir, desassimilar e, no entre, deixar passar o Outro, sem obliterar a alteridade. Em suma, écart e entre promovem a partilha que é a tradução.
