Language Teaching for Bilingual and Multilingual Individuals: Pedagogical Challenges and Curriculum Development
(IGI Global Scientific Publishing, 2026) Sarıçoban, Arif; Bafralı, Görsev; Yardımcı, Aylin
In a world increasingly shaped by globalization, mobility, and migration, linguistic diversity is no longer a peripheral concern in education, it is central. Classrooms across the globe are becoming vibrant spaces of multilingual interaction, where students bring with them diverse linguistic and cultural repertoires. Yet educational systems often remain anchored in monolingual ideologies that fail to reflect this new reality. There is a pressing need for pedagogical, curricular, and policy shifts that acknowledge and embrace multilingualism as an educational asset rather than a challenge. Language Teaching for Bilingual and Multilingual Individuals: Pedagogical Challenges and Curriculum Development critically examines the limitations of conventional language instruction and offers actionable strategies for fostering inclusive, equitable, and linguistically responsive educational practices. This book addresses the pedagogical challenges and curriculum development needs related to the education of bilingual and multilingual individuals. Covering topics such as generative artificial intelligence, monolingual norms, and overlapping marginalization, this book is a critical academic resource for graduate and doctoral students, language educators, curriculum developers, policymakers, linguists, and more.
Evaluating the Impact of Independent Auditing on the Sustainability Performance of Freight Transportation in a Type-2 Neutrosophic Fuzzy Environment
(Springer Nature, 2026) Görçün, Ömer Faruk; Durmuş, Cem Niyazi; Şener, Sefer; Çanakçıoğlu, Mustafa
This study addresses freight transport firms’ challenge of assessing financial audit practices on sustainability and financial performance under high uncertainty. Limited sector-specific research hinders prioritization. A Type-2 Neutrosophic Fuzzy Sets (T2NFS)-based Gray Relational Analysis (GRA) method is proposed, where T2NFS handles expert judgment ambiguity and GRA ranks audit alternatives. Findings show “Contribution to Sustainability” (C10) as the top criterion and “FD-07 Receivables and Payables Aging Analysis” as the most critical audit practice.
Evaluation of Sustainable Distribution Network Design Decisions for Essential Medical Products in Turkey
(Frontiers Media SA, 2026) Safaei, Mehdi; Yahya, Khalid; Al Dawsari, Saleh
Introduction: Optimization of distribution for essential medical products is important goal in health systems. For this purpose, the network design should consider economic, environmental, and social aspects together. This issue is especially serious in Türkiye, where regional disparities, infrastructure differences, and limited access to healthcare make pharmaceutical distribution more complicated. Methods: This study develops a tri objective mathematical programming model for sustainable distribution network design of essential medical products in Türkiye. The model tries to minimize logistics cost and carbon emission at the same time, while it maximizes social benefit through regional job creation. Since the problem is NP hard, two multi objective metaheuristic algorithms, NSGA II and MOPSO, were applied for solving large scale instances. Their performance was evaluated by mean ideal distance, spacing metric, number of Pareto solutions, and computational time. Validation was done through comparison of metaheuristic results with exact MILP solutions in small scale instances. Results: The results show that both algorithms produced near optimal solutions with good quality. MOPSO had faster convergence, lower mean ideal distance, and also more uniform Pareto front, while NSGA II gave wider spread of alternative solutions. No statistically significant difference was found in the number of non-dominated solutions. The case study results also show that the proposed model can help simultaneous improvement of economic, environmental, and social performance in Turkish healthcare distribution network. Discussion: The proposed framework gives a practical decision support basis for sustainable and resilient healthcare distribution network design in Türkiye. Its contribution is that it brings together cost, carbon emissions, and regional employment generation in one unified multi echelon optimization structure, and also shows that metaheuristic solution methods can be useful for real world healthcare logistics planning.
Green Leadership: A Scientific Paradigm or a Managerial Fashion?
(Emerald Publishing, 2026) Kılınç, İzzet; Özçelik, Gülizar; Ertem, Mehmet; Ünal, Aslıhan
Purpose – Thisstudy critically exploresthe increasingly popular concept of green leadership within managerial and academic discourse. Although frequently presented as an ethically grounded leadership model aligned with sustainability goals, its maturity as a scientific paradigm remains questionable. The paper evaluates whether green leadership possesses the conceptual coherence, methodological structure, and problem-solving capacity necessary to qualify as a paradigm. Design/methodology/approach – Drawing on Thomas Kuhn’s theory of paradigms, the study examines the conceptual foundations of green leadership and assesses its theoretical and methodological status. It further incorporates insights from Abrahamson’s concept of management fashion and employs a critical management studies lens to explore the discursive construction of green leadership. Additionally, the analysis integrates Popper’s falsifiability criterion and Lakatos’s research programme model to evaluate the concept’s scientific rigor. Findings – The analysis suggests that green leadership largely draws on transformational, ethical, and sustainable leadership approaches without offering an original theoretical foundation. From this perspective, it resembles a management fashion more than a paradigmatic framework. The study argues that the normative positivity surrounding green leadership may contribute to legitimizing existing organizational powerstructures. Furthermore, it identifies Western-centric development and universalist assumptions that challenge the concept’s cultural adaptability in non-Western or developing contexts. Overall, the findings conclude that green leadership currently lacks sufficient explanatory power, conceptual coherence, and theoretical maturity to be considered a scientific paradigm. Originality/value – This study contributes by systematically evaluating green leadership through the lens of paradigm theory and the philosophy of science. It moves beyond normative and symbolic representations of green leadership and provides a critical and interdisciplinary perspective that highlights its conceptual limitations and cultural blind spots. The study emphasizes the need for further theoretically grounded, empirically robust, and culturally sensitive research to enhance the legitimacy and practical relevance of green leadership.
Elevated Oxidative Stress and Impaired Antioxidant Defense in Idiopathic Sudden Sensorineural Hearing Loss: A Case–Control Study
(Istanbul University Press, 2026) Özkan, Hüseyin; Tabaru, Alper; Rüzgar, Sedat; Bozan, Nazım
Objective: Sudden sensorineural hearing loss (SSNHL) is an acute otologic emergency that can profoundly affect quality of life. Although various mechanisms, including viral, vascular, and immune-mediated pathways, have been proposed, most cases remain idiopathic. Oxidative stress has been suggested as a potential contributor by disrupting the balance between reactive oxygen species (ROS) and antioxidant defences within the cochlea. This study aimed to investigate serum oxidative stress markers and antioxidant enzyme activities in patients with idiopathic SSNHL compared with healthy controls. Materials and methods: This case–control study included 30 patients diagnosed with idiopathic SSNHL and 30 ageand sex-matched healthy volunteers. SSNHL was defined as a ≥30 dB loss over at least three contiguous frequencies within 72 hours, with secondary causes excluded. Blood samples were collected at presentation before treatment initiation. Serum malondialdehyde (MDA) levels and antioxidant parameters, superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and reduced glutathione (GSH), were measured using commercial spectrophotometric assay kits. Between-group comparisons were performed using appropriate statistical tests. Results: Patients with SSNHL exhibited significantly elevated oxidative stress. Mean serum MDA levels were 1.66±0.29 µmol/L in the SSNHL group versus 0.69±0.09 µmol/L in controls (p
