Semi r-ideals of commutative rings
Authors: Khashan Hani A. , Celikel Ece Yetkin 
Published: February 2025

Abstract
For commutative rings with identity, we introduce and study the concept of semi r-ideals which is a kind of generalization of both r-ideals and semiprime ideals. A proper ideal I of a commutative ring R is called semi r-ideal if whenever a
2 ∈ I and Ann
R(a) = 0, then a ∈ I. Several properties and characterizations of this class of ideals are determined. In particular, we investigate semi r-ideal under various contexts of constructions such as direct products, localizations, homomorphic images, idealizations and amalagamations rings. We extend semi r-ideals of rings to semi r-submodules of modules and clarify some of their properties. Moreover, we define submodules satisfying the D-annihilator condition and justify when they are semi r-submodules.

Published: February 2025

Abstract
In this paper, we bring into light, study the polygonal structure of Fibonacci polynomials that are placed clockwise on these by a number corresponding to each vertex. Also, we find the relation between the numbers with such vertices. We present a relation for obtained sequence in an n-gon yielding the m-th term formed at k vertices. Also, we apply these situations to Lucas polynomials and find new recurrence relations. Then, the numbers obtained by writing the coefficients of these polynomials in step form are shown in OEIS.

Published: February 2025

Abstract
In this paper, we have determined the generators and rank of a 2D cyclic code of length mn over a finite chain ring ℛ with residue field 𝔽
q
, where m is arbitrary and q ≡ 1(mod n). Further, we have obtained a necessary and sufficient condition for a 2D cyclic code over a finite chain ring ℛ to be MHDR. Some examples of 2D cyclic codes have been constructed and ranks of these 2D cyclic codes have been calculated by us. We have also given a few examples of 2D cyclic codes over some finite chain rings, which are MHDR.
The Extraordinary World of Sulphur Part 2
Authors: Szydło Zbigniew A. 
Published: February 2025

Abstract
Sulphur is a highly reactive element, and is therefore able to enter into a wide variety of chemical combinations, resulting in the formation of compounds of widely differing properties. Reactions involving sulphur, and the compounds which they produce, have stimulated and inspired people throughout the ages. Sulphur has always been associated with volcanoes, fires and smells. However, its story goes much further; sulphur is present in thousands of products of the chemical industry, which are in everyday use. These include car batteries, tyres, matches, paints, paper, textiles, food, detergents and pharmaceuticals. In Part 1 of this essay, the evolution of the role of sulphur in the history of mankind has been explained, through the lenses of etymology, geology, literature, art and chemistry. In Part 2, the role of sulphur in biochemistry and chemical technology is reviewed. In presenting these facets of the world of sulphur, a case is established, to show that sulphur is one of the most useful and interesting substances known to Man.
Microwave-Aided Nitration of Phenol with Inorganic Nitrates: Inquiry-Based Learning Experiments
Authors: Morávková Zuzana , Havlíček Jiří , Doležal Rafael , Bílek Martin , Kolář Karel 
Published: February 2025

Abstract
Current trends in organic synthesis as well as in chemistry education highlight the principles of Green chemistry and call for new synthetic procedures that conform to the actual ecological and economic requirements according to the Green deal and other global challenges. This includes, for instance, replacement of aggressive and toxic reagents, optimisation of synthetic protocols to achieve the highest possible yields within the shortest reaction times, lowering the reaction temperature, solvent recycling and waste minimisation. Considering the present technological advances, replacement of classical heating by microwave irradiation turns out to be an important tool of Green chemistry that permits significant reduction of the reaction time and increase of the yield under certain conditions. In chemistry education alike, several teaching experiments have also been reported in the latest literature to show advantages of the microwave-aided synthesis of various organic compounds or to elucidate basic chemical reactivity principles (e.g. direct carboxamide synthesis, aromatic sulphonation with rearrangement). In the present study, we design a Green chemistry education project focused on microwave-aided nitration of phenol by a set of inorganic metal nitrates (i.e. sodium nitrate, calcium nitrate, copper(II) nitrate, iron(III) nitrate) in concentrated acetic acid. These inquiry-based learning experiments proceed very easily, and the reaction conditions can be controlled to achieve the first, the second or even the third degree of nitration. Along with a necessary minimum of chemistry knowledge and skills, the proposed educational experiments on microwave-aided synthesis encourage students to explore the influence of the inorganic nitrate structure on the phenol nitration products. The basic relationship between the properties of reactants and the course of this interesting organic reaction can be easily monitored by universal pH papers and thin-layer chromatography, and subsequently explained through inductive reasoning. As such, these student-centred experiments are suitable for implementation in inquiry-based chemistry education at universities or high schools oriented in natural sciences.
Engaging in Online Environmental Discussion: Experiences and Reflections of Students in an Undergraduate Science Course
Authors: Kazempour Mahsa 
Published: February 2025

Abstract
Environmental and sustainability-focused education plays an integral role in positively influencing students’ levels of environmental awareness, competencies, and adoption of sustainable decision making and behavioral practices. Media and information technology have been identified as possible factors influential in shaping the youths’ level of environmental literacy and perceptions of environmental issues. Yet, due to format and scope of coverage and lack of emphasis on the importance of the environment and consequences of human action, the role of mass media may at times be inadequate or unsuitable, leading to eco-anxiety. The literature on the connection of students’ media and information literacy (MIL) and environmental literacy (EL), especially in college settings, remains scarce. This mixed-method study explored the experiences of students in an introductory college science course with a weekly discussion forum designed to engage them in learning about environmental issues through various media platforms and participation in peer discussions. This study examined the types of environmental topics students focused on and students’ experiences and reflections as they engaged in environmentally focused media content and peer discussion. The findings indicated that students obtained mainly national and international news stories from major mainstream news media outlets, followed by online science or environment-focused news outlets. They gained awareness of environmental concerns in various geographical locations, the negative impact of human activity on the environment, as well as various means of positive human impact through ecological footprint reduction solutions and actions.
Using Large Scale Summative Tests to Advance the Integration of Sustainable Development Competencies: A Model for Test Construction
Authors: Williams-McBean Clavia T. 
Published: February 2025

Abstract
There is an urgent need for global citizens to develop sustainable development competencies (SDCs) if our world is to survive threats to its development and sustainability. These competencies can be developed through education for sustainable development (ESD). However, implementing ESD is challenged by teachers’ and students’ prioritisation of the assessed curriculum while ESD remains largely unassessed in the education sector. The knowledge, skills, values and attitudes reflected in tests and assessments, especially large-scale, standardised, summative tests, influence classroom practices considerably. This paper proposes that the integration of SDCs can be accelerated by constructing large-scale tests to measure these competencies, thereby capitalising on the influence of the tests. It presents a model for constructing these tests and provides ways in which the format of multiple choice and extended written response items may be optimised to measure SDCs.
A Bibliometric Analysis of Research on Teachers’ Digital Competences
Authors: Gündüzalp Seda , Yaraş Zübeyde 
Published: February 2025

Abstract
Global events have become a driving force for digital transformation in education. In the digital transformation process, education systems have started to evolve within a digital infrastructure and have gone beyond traditional education patterns. This process has reshaped education systems and increased the importance of digital competence. Therefore, in this digital transformation process, teachers’ digital competence levels have emerged as a critical concept for the sustainability of education systems and the effectiveness and efficiency of education, and as a prerequisite for the effectiveness of learning processes. As a result, many academic studies have been conducted in recent years to investigate this need. The aim of this research is to analyze academic studies that focus on teachers’ digital competence using bibliometric analysis methods. Among the results, it was found that the number of publications has been steadily increasing, with Spain being the country that produces the most publications in the field concerning teacher digital competence.
Unlearning Dance: Reclaiming the Power of Dancing
Authors: Ginkevičiūtė Ieva , Gin Indre 
Published: February 2025

Abstract
The Unlearning Dance: Reclaiming the Power of Dancing research workshops, led by artists and educators Agus Margiyanto, Ieva Ginkevičiūtė, Indrė Gin, and Retno Sulistyorini, explore the unlearning dance process. This ongoing collective research aims to reconsider institutionalised and commercialised narratives in dance across various contexts, as these narratives often restrict personal expression and marginalise diverse cultural and individual perspectives. Through workshops and collaborative inquiry, the authors explore entrenched habits in dance education in terms of the body, myths, and power dynamics. The research workshops draw attention to how participants reconnect with their embodied memories, discover movement habits, and reclaim dance as subjective and inclusive practice. Ultimately, this research expands the understanding of dance as an evolving, decentralised form of expression, with significant implications for both education and performance.
The Dancing We
Authors: Buttingsrud Camille , Kilsgaard Ellen 
Published: February 2025

Abstract
In the 2023 intergenerational dance project Superpower Ensemble, the participants were chosen for their individual qualities to form a greater ‘we’ as a group. The children added spontaneity and playfulness, whereas the adult artists inspired the children with their artistic practice, professionalism, and direction. In this article, we aim to describe the subtle processes a choreographer initiates to achieve the intended aesthetic and ethical results. Our case story is Superpower Ensemble, and the theme investigated through the case story is ‘we-ness’. By describing these processes and this theme, we seek to demonstrate some of the manifold forms of knowledge possessed by dancers, choreographers, and artists. Their practically gained expertise in being, being together, and being in the world has the potential to reach far beyond the artistic realm. Their findings align with academic insights into metaphysical, philosophical realms. To show the latter, we outline certain theoretical and philosophical discoveries that reinforce the findings unearthed and explored through the bodily–affective dance work in Superpower Ensemble.
The Role of Well-Being as a Value in Students’ Health-Conscious Lifestyles in the Context of the Role of Daily Physical Education
Authors: Moravecz Marianna , Kovács Karolina Eszter 
Published: February 2025

Abstract
The Geneva Charter for Well-being (2021) states that for the health and well-being of the planet, society, community and individuals, we must support changes in social structures that help people take control of their own lives and health. The crisis of sport and health as values may also indirectly affect the value preferences of the younger generation regarding their lifestyle choices and the vision of society. The research investigates the impact of value transfer beyond the apparent boundaries of sport on the lifestyle and well-being of university students who regularly participate in sport and those who are physically passive. 1521 students learning at the University of Debrecen and the University of Nyíregyháza completed our online questionnaire, which integrated questions on socio-demographic background, physical health status, mental status, stress workload, risk index, physical activity index, eating patterns and value preferences. Univariate and multivariate analysis methods were applied. Our study values suggest an increasing search for a sense of safety in the age group, independent of sporting activity (this may also raise questions about the social background of the disadvantaged region). Our results show that students mainly emphasised the “open” or post-material value dimension of individual autonomy in the relationship between sports activity and value orientation. A complex mechanism of action can be experienced when examining value orientations, so we cannot show any causal links in our analysis. This study highlights the complex relationships between personal values and health behaviours among university students. It reveals that material, traditional and autonomy-oriented values influence health perceptions and certain lifestyle choices The relevance and novelty of our study is that the new generation of students who have already participated in the new implementation process in physical education and who have already been involved in the public education system has not yet been studied from this point of view.
Differences in Balance Ability Between Female Dancers and Active Non-Dancers
Authors: Bochenek Marcin , Sacewicz Tomasz , Cieśliński Igor 
Published: February 2025

Abstract

Introduction.
Balance is used in almost every movement task; it is a complex process that requires control and is based on the interaction of the musculoskeletal and nervous systems. It depends on many external and internal factors, which include genetics, age, center of gravity, support area, emotional state, concentration, strength, coordination skills, flexibility, and visual control, as well as the frequency of participation in motor activities and training status. The study aimed to compare the balance of female dancers and non-dancers using the MyoPressure-T Noraxon FDM-T AC 5000m baroresistive treadmill.

Material and Methods.
The study involved a total of 128 women aged 20-26 in two groups: dancing and non-dancing. Based on the tests performed, the center of gravity deflection, the length of the COP (center of pressure) path, and the reaction of ground forces in both groups were analyzed. Additionally, an analysis of lower limb loads during walking and running was performed using the parameter Force max. [N] – maximum pressure force. The hypotheses of normal distribution were rejected using the Shapiro-Wilk test for all variables. The hypotheses of equal variance for all variables were rejected using the F test. The nonparametric Kruskal-Wallis test was used to assess the significance of differences and the effect size between the study groups.

Results.
The results of the dancers (95% confidence ellipse area) were better than those of the control group. This is visible in both the Romberg test with open and closed eyes. In the case of COP average velocity, there are no differences with open eyes, but statistically significant differences appeared in the test with closed eyes. The analysis of Maximum Force, N, during walking did not show statistically significant differences between the groups. They appeared only while running in favor of the dancers.

Conclusions.
The study results confirm the hypothesis that women who dance have better static balance than women who do not participate in dance classes. The study provides new evidence regarding balance in dancers and non-dancers.

This study highlights the complex interplay of social, cultural, and religious factors in shaping gender roles within co-preneurial businesses in Indonesia. Using an empirical qualitative approach, the research incorporates in-depth interviews with seven co-preneurial couples from diverse cultural backgrounds i.e. Javanese, Minangkabau, and Mandarese ethnicities in Indonesia. The findings reveal that co-preneurial couples often challenge traditional gender stereotypes by establishing equitable roles based on individual capacities rather than societal norms. This flexibility is underpinned by mutual trust, effective communication, and respect, crucial for entrepreneurial endeavour. Cultural analysis shows that Javanese and Mandarese cultures, while patriarchal, allow for adaptable role distributions. Meanwhile, Minangkabau culture which is matrilineal is being more gender balanced. From a religious perspective, all participants view Islam as advocating for collaborative efforts between male and female in business and promoting balanced gender roles. Despite traditional biases favouring male dominance in work and industry, current trends indicate increasing female involvement in business activities, challenging long-standing stereotypes. The study identifies potential disadvantages, including conflicts arising from the overlap between personal and professional roles and underlying cultural and social biases influencing role dynamics. The study implies that advocating more intensive gender equality, establishing clearer professional boundaries, developing supportive policies and legal frameworks to foster an equitable co-preneurial environment are still needed, which should emphasize the importance of mutual respect, trust, and flexibility in creating balanced and productive business partnerships, contributing valuable insights into the intersection of law, culture, and entrepreneurship.
