Fostering student engagement during teaching practicum: pre-service EFL teachers’ strategies
Authors: Salsabila Iqlil
Published: February 2025

The lack of student engagement greatly influences the implementation of the learning process. This is very important because it refers to the pre-service teacher’s ability to manage the class so that it runs effectively and involves all students. This study explores the strategies pre-service teachers use to increase student engagement. This research was designed with a case study approach. Four pre-service EFL teachers were selected as participants in the research. In collecting data, the researcher used semi-structured interview techniques and observations through video recordings of teaching carried out by each participant. The data were analyzed using thematic analysis. The findings revealed that there were six strategies used to increase student engagement during teaching practicum, including measuring student engagement, establishing good communication between pre-service teachers and students, balancing structure and student autonomy through cooperative learning methods, promoting digital media as an innovation in the learning process, providing evaluation questions, and increasing the engagement of students with exciting activities. This study concludes with pedagogical implications for how pre-service teachers can use strategies to increase student engagement in English learning during teaching practicum.

Published: February 2025

The emergence of pesantren without kiai signifies a diversification in the leadership and ownership models of pesantren in Indonesia. This study investigates the transformation of leadership and ownership in two pesantren located in Pekalongan, specifically Pondok Modern Al-Qur'an Buaran and International Muhammadiyah Boarding School (IMBS) Miftahul Ulum Pekajangan, both of which were established by non-kiai founders. Employing a qualitative-phenomenological approach, this research utilizes single-site and cross-site data analysis as modeled by Robert K. Yin. The findings indicate a transition from a traditional family-based leadership model to a more organizational structure. Furthermore, the ownership of pesantren has shifted to foundations or Islamic organizations. Consequently, the selection of pesantren caregivers is now determined by the institution or organization rather than by lineage. Nevertheless, the diverse leadership and ownership models do not reduce the interest of the community sending their children to these pesantren.

Published: February 2025

The implementation of elections as an embodiment of democracy is closely related to territorial structures at national, provincial, and autonomous district levels. The Supreme Court has the authority to resolve election administration violations, including decisions that cancel the participation of candidate pairs in regional head elections. The dispute over the election of the Boalemo Regent and Deputy Regent brought to the Supreme Court for judicial review raises questions about the Supreme Court's authority under Article 154 paragraph (10), which states that the final legal remedy is cassation. This research is normative juridical research using legislative, conceptual, and case approaches, with data collected from primary, secondary, and tertiary legal materials. Analysis is conducted after data is inventoried and systematized. The results show that Article 153 paragraph (10) of Law Number 10 of 2016 states that the Supreme Court's decisions are final and cannot be subject to judicial review. The decision of the Boalemo Regency Election Commission, which established a new candidate pair after the cassation decision, violates the principle of legal certainty. The Cassation Panel stated that the candidate pair eligible to participate in the 2017 Boalemo Regent and Deputy Regent Election was Rum Pagau and Lahmudin Hambali, according to the Decree of the Boalemo Regency Election Commission.

Published: February 2025

The fulfillment of civil registration rights for people with mental disorders (ODGJ) in Kalirejo Village, Talun Subdistrict, Pekalongan Regency, is an important issue that requires serious attention. Based on Law Number 23 of 2006 concerning Civil Registration, every Indonesian citizen has the right to obtain civil documents such as an Identity Card (KTP) and Family Card (KK). However, in practice, many individuals with mental disorders in Kalirejo Village lack these essential documents, preventing them from accessing social and healthcare services that are their rightful entitlements. This study aims to analyze the factors contributing to the non-fulfillment of civil registration rights for ODGJ, as well as the implications arising from this situation. The research employs a qualitative approach with an empirical juridical method. Primary data were collected through interviews with village officials, families of ODGJ, and direct observations in Kalirejo Village, while secondary data included legal documents and literature related to the fulfillment of civil registration rights. The findings reveal that the main barriers to the fulfillment of these rights are the low level of legal awareness among the community and the limited proactive efforts by village authorities. The implications of this situation include restricted access for ODGJ to healthcare and social assistance services to which they are entitled, worsening their health conditions and increasing social marginalization within the community.

Authors: Osmala-Kurpiewska Weronika , Niesler Anna , Domagalska Joanna , Rusin Monika
Published: February 2025

Introduction

Due to the COVID-19 pandemic, many employees, students, and children had to switch to remote work and learning. This has led to an increase in the amount of time spent near devices that emit electromagnetic radiation.

Aim

The aim of the study was to determine the exposure to low frequency electromagnetic fields (EMF) during remote working and learning. In addition, the study attempted to estimate the amount of time spent using computers or laptops and to determine the health effects resulting from exposure to EMF while studying and working remotely.

Material and methods

An original survey of 117 adults working remotely and 53 parents of children studying remotely during the COVID-19 pandemic was conducted between November 2022 and May 2023. The results were analyzed statistically. In addition, measurements of the low frequency EMF that is emitted in residential areas have been conducted.

Results and Discussion

Adults and children spent an average of approximately 7 h per day in front of a computer during the pandemic, compared to an average of approximately 3 h per day during the pre-pandemic period (P < 0.01). An association was found between the lack of breaks in remote learning and children's irritability.

Conclusions

During the COVID-19 pandemic, the time allowed for working and learning has been significantly extended. The most common health symptoms reported by study participants were headaches, frequent fatigue, and irritability.

Published: February 2025

In this paper, we consider the construction of an optimal lattice quadrature formula
in the space W(m)
2 (0; 1). We derive an analytical expression for an error functional norm and obtain
a system of linear equations of Wiener-Hopf type by the coefficients using the method of Lagrange
multipliers. Further, we apply the Sobolev method to get the analytical representation of the optimal
coefficients. Using these coefficients, we calculate the norm of the error functional of the optimal
quadrature formula for m = 2 in W(m)

Authors: Azamov S.S. , Tursunmuradov S.T.
Published: February 2025

The problem of constructing optimal quadrature and interpolation formulas for approximate calculation of definite integrals and approximation of functions is one of the important
problems of computational mathematics. These problems have been studied by many mathematicians
and there are several methods for constructing optimal quadrature and interpolation formulas. One
of these methods is the method proposed by S. L. Sobolev with the concept of an extremal function
of the error functional. In this paper, in a specific Hilbert space, finding an extremal function of the
error functional of quadrature formulas is considered. The square of the norm of the error functional
is calculated. To find the optimal coefficients, a system of linear algebraic equations is obtained. The existence and uniqueness of the resulting system are investigated.

Published: February 2025

In the current socio-economic context and given the situation that adolescents and young people face when accessing the labor market, a firm and coordinated response is needed at all levels in order to assure good career guidance. There is a contrast between the enormous challenges that we face today and both the fact that educational laws in recent history have failed to incorporate substantial changes regarding career guidance, as well as the scarce resources that are allocated to career guidance in education. It is evident that there is a need for a strong commitment to quality career guidance at school, a context in which teachers have a prominent role when it comes to positively influence their students’ decisions. This text offers a classification and practical examples of how to integrate career guidance in different subjects in secondary education. Teachers’ activities should be aligned with the school’s strategic plan regarding career guidance and assume a competency-based approach, in order to allow students to develop educational, labour and career management competencies.

Chaos to Cosmos: Quantum Whispers and the Cosmic Genesis
Authors: Owais Farooq , Romana Zahoor
Published: February 2025

Quantum fluctuations, usually arising from the inherent uncertainty in the quantum fields, are pivotal in understanding the universe at both the small and large scales. Even though fluctuations are usually unobservable and rather small, they give significant observable effects during specific epochs under specific conditions. During the early epochs of the universe, the fluctuations were scaled, resulting in the primordial density perturbations that gave rise to the large-scale structure of the universe and the observed inhomogenities. In this paper, we study the basic origin, structure, evolution, and imprints of fluctuations during the inflationary period resulting in large-scale structure formation. We use the Mukhanov-sasaki formalism to model scalar perturbations, embedding the theoretical results into observations. Theoretical predictions show an almost scale-invariant power spectrum with stringent constraints on the inflationary parameters. It further states that in the very early universe, the inflatons that are quanta of the primordial field were highly filled in the degenerate quantum state. This carries large potential energy that results in an exponential expansion of the universe. During post post-inflationary period the inflaton dominated the Universe’s energy density; they interact among themselves and due to non-linear effects, these inhomogeneities grow which amalgamate into spatially distinguishable patches in our observable universe. Our understanding projects us towards the fact that fluctuations play a pivotal role in understanding the structure formation at micro, macro, and far-macro scales. This study also addresses the significance of quantum fluctuations in cosmic evolution and manifests the enduring relevance in addressing some of the profound mysteries of our universe.

Background: Many ready to eat foods are packaged with single use plastics and Styrofoam that are rarely cleaned, washed or sterilized before use by food vendors, at home and public events. These surfaces harbour bacteria which contaminate the food and result in food-borne diseases when consumed along with the food by susceptible individuals, leading to illnesses and possibly death. This study assessed the status of bacterial contamination and antibiotic susceptibility profile of bacteria isolates from new and unused Styrofoam and single use plastics sold in Orlu, Imo State Nigeria.
Methodology: A total of thirty (30) Single Use Plastics bought from random outlets in Orlu international market were analyzed using standard microbiological techniques for bacterial isolation and identification, followed by antibiotic susceptibility testing using the disk diffusion method.
Result: The total bacterial count ranged from 1.1 X 105 to 9.0 x 105 CFU/ml. Six bacterial genera were identified, with Staphylococcus aureus being the most prevalent 70 (32.4%), followed by Clostridium sp. 46(21.3%), Pseudomonas aeruginosa 37(17.1%), Bacillus sp. 35(16.2%), Streptococcus sp. 20(9.3%), and Escherichia coli 8(3.7%). Antibiotic susceptibility was evaluated against seven commonly used antibiotics: Amikacin, Bacitracin, Ceftazidime, Clindamycin, Gentamicin, Mupirocin, and Ofloxacin. Amikacin demonstrated the highest effectiveness with near-complete susceptibility across most isolates, while variable resistance patterns were observed for other antibiotics. Notable resistance was found against Bacitracin (15.4-50%) and Ofloxacin (8.3-33.3%) across different bacterial species. A Multiple Antibiotic Resistance Index (MARI) analysis revealed high levels of multi-drug resistance, with values ranging from 0.42 to 0.71, being highest in Clostridium sp. isolates from both Styrofoam and single-use plastics. All bacterial isolates exhibited MARI values exceeding 0.2, indicating high-risk sources with significant antibiotic exposure.
Conclusion: The presence of these multi-drug-resistant strains on unused food-contact materials raises significant public health concerns, particularly given the widespread use of these materials in food packaging and service industries. These findings emphasize the need for enhanced quality control measures during manufacturing and storage, stricter hygiene protocols, and regular monitoring of antibiotic resistance patterns in food-contact and packaging materials.

As a widely used Intensity Modulation and Direct Detection (IM/DD) system, Asymmetrically Clipped Optical Orthogonal Frequency Division Multiplexing (ACO-OFDM) is considered one of the most promising modulation techniques for high-speed optical communications. Conventional ACO-OFDM uses Hermitian Symmetry (HS) to guarantee a real signal, which results in high computational complexity. The Real Discrete Fourier Transform (RDFT) and Discrete Hartley Transform (DHT) offer alternative approaches to generating real-valued OFDM signals without the need for HS. In the existing literature, various modified techniques have been proposed to enhance ACO-OFDM in terms of bit error rate (BER) or spectral efficiency. However, these methods often suffer from high computational complexity or poor BER performance due to DC offsets and low-frequency noise. To the best of our knowledge, few studies have explored low-complexity yet improved ACO-OFDM schemes that use alternatives to the conventional Discrete Fourier Transform (DFT). In this context, this paper investigates the implementation of Diversity-Combining (DC) and Improved Noise Cancellation (INC) techniques using the Discrete Hartley Transform (DHT) and Real-DFT in an ACO-OFDM scheme over an Additive White Gaussian Noise (AWGN) channel. Simulations conducted in MATLAB 2021 show that both DHT-based and Real-DFT ACO-OFDM achieve similar BER performance compared to conventional ACO-OFDM. Furthermore, the proposed schemes demonstrate a 3 dB power gain in an AWGN channel over traditional ACO-OFDM. Given their low complexity and high performance, DHT-based and Real-DFT INC-ACO-OFDM emerge as promising candidates for optical network systems. Among them, DHT-based solutions are particularly advantageous due to their lower computational complexity.

Personal branding is a critical tool in public relations (PR), affected by the evolving landscape of globalized communication. The dynamic digital environment poses challenges for PR practitioners, requiring them to ensure their communication efforts are acknowledged amid social, economic, and cultural shifts. This research examines the effect of PR strategies on personal branding, communication practices, and organizational reputation, guided by impression management theory. Data acquired from 291 PR professionals in Kuwait is further evaluated using partial least square-structural equation modelling. Findings showed that PR strategies significantly affect personal branding, indicating that the relevant organizations focus on personal branding by adopting PR strategies in the best possible manner. The effect of PR strategies on communication practices further remained significant as respondents revealed PR practices to improve organizational communication. Finally, the proposed effect of PR strategies on reputation management among organizations also remained significant. Gathered data indicated certain PR initiatives, strategies, communication efforts, mitigating reputational threats, and others to ensure reputation management by the relevant practitioners. Thus, the results offer valuable insights for PR practitioners in Kuwait to navigate the online environment and strategically cultivate their brands to improve individual and organizational reputations. Recognizing the significance of PR strategies in personal branding and reputation management helps professionals position themselves effectively in the digital sphere, eventually contributing to the success of individual careers and organizational goals.
Naming/Meaning Distinction Delineated in the Context of The Essence/Existence Distinction
Authors: Samraj Tennyson
Published: February 2025

The epistemic nature of truth provides the basis of understanding the relationship between the naming/meaning distinction and the existence/essence distinction. Every word denotes a reductive reference and connotes a non-reductive meaning. Every word is associated with both intension/meaning and extension/ reference (Putnam). A noun is a naming word; like all words, it denotes a reference and connotes meaning. The distinction between naming and meaning with reference to nouns is necessary because nouns like all words, deal with both extension and intension. The essence/existence distinction defines why it is essential to separate naming from meaning. For naming and existence is an ontological matter; meaning and essence is an epistemic matter. What does a word or specifically a noun entail? It can ascribe (1) the identity of a person, place, or principle; (2) it can affirm the existence of something (material/ concrete world); the subsistence of something (mathematical/ abstract world), or the absistence of something (mental world, F.N. Findlay); or (3) it can define the essence of something as being an essential, accidental, or emergent property. The central thrust of my paper is to discuss why words/ nouns can be understood as either defining the identity and existence of something or defining the meaning and essence of something. There are no nouns/words without reference or meaning. When we see something, what conjures in our mind is either the existence of that thing or the essence of that thing. Naming deals with the specificity and existence of something, while meaning deals with the universality and essence of something. Naming puts emphasis on what is reductive, and meaning puts emphasis on what is non-reductive. Naming and meaning like existence and essence are intertwined because the truth of existence (including subsistence and assistance) and the truth of essence are inseparable, if truth is an epistemic matter. Essence/ existence distinction is fundamental to what exists, subsists or absists in understanding the relationship of the naming/meaning distinction.

This paper establishes a rigorous theory of homology for fractal manifolds with non-integer Hausdorff dimensions DH, and it derives the duality between fractal and classical homology through a generalized Poincar´e duality. By integrating category theory and geometric measure theory, we define fractal chain complexes, prove the Fractal Stokes’ Theorem, and construct weighted homology groups H(α) n (X). Further, we obtain the beta function β(DH) governing dimensional renormalization f low in the fractal AdS/CFT correspondence and validate it via holographic stress tensor anomalies. High-dimensional fractal numerical algorithms (including cellular automata and Monte Carlo methods) are developed, alongside explicit conformal block expansions in fractal conformal field theory (CFT). This work bridges fractal geometry, quantum gravity, and condensed matter physics, providing testable predictions for cross-dimensional phenomena.
Engagement-based algorithms disrupt human social norm learning

As we increasingly learn from others in online spaces regulated by engagement-based feed-ranking algorithms, it is important to understand the impact that these algorithms have on our social learning. In three pre-registered studies (N = 6107), we isolated the effects of feed-ranking algorithms on social norm learning by training algorithms on passive and active engagement in a simulated social media environment. We found that engagement-based algorithms systematically amplified ingroup-aligned, moral and emotional (IME) political content, leading IME content to become overrepresented in feeds. The overrepresentation of IME content in feeds caused participants to overperceive norms of posting IME content, which mediated user intentions to post more IME content. A bridging algorithm successfully reduced IME content in feeds, but also led to underperception of some IME content, suggesting that bridging-based algorithms do not straightforwardly promote more accurate social learning. Our findings shed light on algorithm-mediated social learning in the digital age, demonstrating that specific human learning biases toward IME content are amplified by engagement-based algorithms in ways that disrupt social norm perception. Our findings highlight a central challenge for engagement-based algorithms: how to promote content in ways that enable users to accurately infer others’ preferences.
Teaching translation technologies: an analysis of a corpus of syllabi for Translation and Interpreting undergraduate degrees in Spain
Authors: Sánchez-Castany Roser
Published: February 2025

In recent years the language industry has been modifying the constantly changing technological skills it demands from translators. In the main translation competence models, technologies are deployed across the curricula and are considered just as important as other skills. However, the training provided in Spanish universities today seems to be still out of step with the real needs and demands of the translation market. This research has two objectives: (i) to investigate and define, by means of an empirical study using a mixed-methods approach, the state of affairs in relation to translation technologies training provided in Spanish universities, and (ii) to compare the data obtained with the real demands of the language industry. To this end, this chapter analyses the technology-based content of the curricula for Translation and Interpreting (T&I) undergraduate degrees in Spain for the 2019-2020 academic year. The results of the analysis of a corpus comprising 994 module syllabi seem to indicate that the curricular content of Spanish T&I undergraduate degrees has not kept pace with the profound changes that have occurred in the professional market over the past decade.
Remembering the truth or falsity of advertising claims: A preregistered model-based test of three competing theoretical accounts
Authors: Nadarevic Lena , Bell Raoul
Published: February 2025

Given the large amount of information that people process daily, it is important to understand memory for the truth and falsity of information. The most prominent theoretical models in this regard are the Cartesian model and the Spinozan model. The former assumes that both “true” and “false” tags may be added to the memory representation of encoded information; the latter assumes that only falsity is tagged. In the present work, we contrasted these two models with an expectation-violation model hypothesizing that truth or falsity tags are assigned when expectations about truth or falsity must be revised in light of new information. An interesting implication of the expectation-violation model is that a context with predominantly false information leads to the tagging of truth whereas a context with predominantly true information leads to the tagging of falsity. To test the three theoretical models against each other, veracity expectations were manipulated between participants by varying the base rates of allegedly true and false advertising claims. Memory for the veracity of these claims was assessed using a model-based analysis. To increase methodological rigor and transparency in the specification of the measurement model, we preregistered, a priori, the details of the model-based analysis test. Despite a large sample size (N = 208), memory for truth and falsity did not differ, regardless of the base rates of true and false claims. The results thus support the Cartesian model and provide evidence against the Spinozan model and the expectation-violation model.

Background: This purpose of this paper is to introduce a new role to the research nurse remit, a term we called the ‘In-Place Research Coordinator’. Aim: To achieve this, we will introduce, explain, and provide examples of how we devised and applied the role of the ‘in-place research coordinator’ within our research between a large university and a large NHS Trust. Discussion: The success of this large inter-organisational research project relied on building positive partnerships and networks over three years. Recognising the challenges of working across different organisations, we created a role for a nurse to serve as an 'in-place research coordinator'. By recruiting directly from the NHS Trust, this coordinator brought valuable organisational insights to the research team whilst gaining research experience through applying their professional knowledge and connections.Conclusion: This paper details, using practical examples, how the role of an ‘in-place’ research coordinator made this interorganisational research happen with measurable efficacy and impact.
