A multi-criteria evaluation of cybersecurity incident management frameworks: integrating AHP, CMMI and SWOT
(Karyay Karadeniz Yayımcılık Ve Organizasyon Ticaret Limited Şirketi, 2026-01-15) Ağar, Hasan Çağlar; Çeliktaş, Barış
With the growing complexity and frequency of cybersecurity incidents, the selection of an appropriate incident management framework has emerged as a strategic imperative and a nontrivial decision-making problem for organizations operating across diverse sectors. This study presents a multi-dimensional evaluation of four globally recognized frameworks and standards—ISO 27035, NIST 800-61, ITIL v4, and PCI DSS—to determine their effectiveness across 10 rigorously selected key performance parameters. The initial stage of the study involved the identification of 20 preliminary parameters through expert input and literature synthesis. These were then evaluated by 70 cybersecurity professionals using a hybrid decision-making model combining Likert scale scoring, standard deviation filtering, CV score, Z-score normalization and the Analytic Hierarchy Process (AHP) for pairwise comparisons. The top 10 key parameters were derived based on calculated priority weights. To assess each framework, we applied the Capability Maturity Model Integration (CMMI) and visualized results via radar charts and heatmaps, offering comparative insights into operational maturity. Additionally, SWOT analysis was conducted to examine strategic positioning and identify opportunities for improvement. The outcomes not only provide a practical benchmarking guide for practitioners but also introduce a replicable, evidence-based methodology for academic and industry adoption. This work offers a novel and structured lens to evaluate incident management maturity, addressing the pressing need for strategic alignment, automation integration, and adaptive resilience in cybersecurity operations.
Psychometric properties of the emotional self-efficacy and prosocial behavior scales among Nigerian youths: a cross-cultural validation study
(Genç Bilge Yayıncılık, 2026-01-06) Akaiso, Emmanuel
This study examined the psychometric properties of the Emotional Self-Efficacy and Prosocial Behavior scales, originally developed in Italy, among Nigerian youths residing in urban and semi-urban contexts. A total of 108 participants completed measures assessing empathic ability, problem-solving, and interpersonal communication, alongside the Prosocial Tendencies Measure, which captures helping behaviors across anonymous, public, and emotionally salient situations. The findings demonstrated acceptable internal consistency across all scales, indicating satisfactory reliability within this cultural context. Descriptive analyses showed generally low levels of empathic and problem-solving selfefficacy, while interpersonal communication self-efficacy ranged from low to high. Correlational analyses revealed that empathic, problem-solving, and interpersonal communication self-efficacy were positively associated with prosocial behaviors, particularly in emotionally demanding contexts. Additionally, empathic and problemsolving self-efficacy were positively related to public prosocial actions. Overall, the findings provide preliminary evidence supporting the cross-cultural applicability of these instruments among Nigerian youths and highlight culturally relevant patterns in selfefficacy and prosocial functioning. The study contributes to the limited literature on psychological resources and prosocial development in Sub-Saharan Africa. Future research should employ larger and more diverse samples and explore the roles of resilience, personality traits, and value orientations in shaping prosocial behavior.
The mediating effect of self compassion in the relationship between job stress and burnout levels among employees
(SAGE Publications Inc., 2026-02-13) Günay, Ezgi; Ünver, Buket; Yılmaz, Simay
Objective: This study investigates the role of self-compassion as a mediator in the relationship between job stress and burnout among employees. While job stress is widely recognized as a critical factor leading to burnout, it has been suggested that self-compassion may be associated with a reduction in these negative effects. Method: Participants were 429 actively employed adults living in Turkey (50.6% female). The data were gathered using an online administration of standardized psychological scales, that is, Job Stressor Appraisal Scale, Copenhagen Burnout Scale, and Self-Compassion Scale. Four dimensions of work stress “Role and Workload, Role Inadequacy, Organizational Rules & Practices, and Subordinate Relations” are taken into consideration in the volumetric model. Path analysis with bootstrapping (5,000 resamples) was implemented using Mplus statistical software, with gender, economic condition, and way of working during COVID-19 as covariates. Findings: The model fit was acceptable in path analysis. Role and workload and role inadequacy had a significant direct impact on burnout. Self-compassion had a significant mediating impact on the relationship between role and workload and burnout and the relationship between role inadequacy and burnout. Conversely, for organizational rules and practices and subordinate relations, both direct and mediating effects were non-significant. The model accounted for 21% and 52% for variance in self-compassion and burnout, respectively. Conclusion: This study emphasises the mediating role of self-compassion in the effect of job stressors on burnout. These findings suggest that interventions promoting self-compassion in the workplace may be effective in reducing employee burnout.
Witnessing the end, supporting the living: A qualitative study of palliative caregiving in end-of-life patients in Türkiye
(Cambridge University Press, 2026-02-11) Sert Yurdakul, Selin; Erbay Erşen, Merve; Özel, Dilara
Objectives. Palliative care seeks to enhance the quality of life for individuals with serious illnesses and their families by addressing physical, emotional, and psychological needs. This phenomenological study examines the lived experiences of 8 caregivers in palliative care settings in Türkiye, focusing on the challenges they face, the coping mechanisms they employ, and their reflections on the caregiving role. Special emphasis is given to both psychological and somatic signs of stress, along with the possible advantages of body-oriented resilience techniques. Methods. Using a phenomenological qualitative design, semi-structured interviews were conducted with 8 caregivers providing care to relatives in a hospital-based palliative care unit. Data were collected between February and April 2023 and analyzed through conventional content analysis. Results. Four central themes emerged from inductive coding: harmony in healing, navigating difficulties, resilience in palliative care, and reflections on the finite. The findings reveal a dual reality: palliative caregivers derive meaning and satisfaction from compassionate connections, high-quality clinical care, and peer support, yet they also endure significant burdens, including emotional strain, physical exhaustion, disrupted daily routines, and shifting relational dynamics. Anticipatory grief and chronic stress responses were prevalent, frequently manifesting in both psychological and somatic forms (e.g., sleep disturbances, muscle tension, and autonomic arousal). Despite these challenges, palliative caregivers employed spiritual beliefs, peer interactions, and self-care routines as resilience strategies. Significance of results. The mind–body challenges identified in the study emphasize the need for interventions that focus on self-regulation and resilience, including body-oriented approaches that strengthen internal resources, regulate stress responses, and encourage adaptability. Incorporating such approaches into group-based settings may improve mutual support and enhance both individual and relational well-being. The study highlights the importance of comprehensive, caregiver-centered support systems to reduce burden and improve the overall quality of palliative care.

Uyumlu mükemmeliyetçilik alt boyutlarından düzen, duygusal tükenme ile negatif yönde, kişisel standartlar alt boyutu ise duyarsızlaşma ile pozitif yönde korelasyon ilişkisine sahiptir. Ayrıca, bulgular psikolojik dayanıklılığın, uyumsuz mükemmeliyetçilik ve tükenmişlik arasındaki ilişkide kısmi aracılık etkisini ortaya koymaktadır. Sonuçlar değerlendirildiğinde, mükemmeliyetçi özelliklerin uyumlu ve uyumsuz mükemmeliyetçilik olmak üzere iki boyutta ele alınmasının, tükenmişlik kavramını anlamada daha detaylı veri sağlayacağı ve psikolojik dayanıklılık gibi tükenmişliğe tampon etkisi yaratabilecek kavramların ele alınmasının önemli olduğu düşünülmektedir.
Polyvagal theory and interoception-based interventions: approaches to strengthen mental resilience
(Psikiyatride Güncel Yaklaşımlar, 2026) Candaş Demir, Merve Umay; Hasateş, Mahmut Can
Humans survive by establishing healthy bonds, and these bonds provide emotional regulation, especially in the caregiver-infant relationship. Polyvagal Theory suggests that the autonomic nervous system supports survival by assessing environmental and internal safety signals. Interoception plays a crucial role in this process, referring to the ability to sense the body's internal states. In recent years, interoception-based therapies have proven effective in the treatment of psychopathologies, especially post-traumatic stress disorder. Interoceptive-based interventions, such as trauma-informed yoga, can improve individuals who do not respond to traditional treatment by enhancing emotional regulation and body awareness. The aim of this study is to examine the effects of humanto-human relationships on mental health in the digitalized world, within the framework of Polyvagal Theory. In particular, it emphasizes the important role of interoception in the bond we establish with ourselves and its significance in psychotherapy. The study proposes an approach that supports mental health by discussing the therapeutic effects of interoception and the role of these skills in improving communication between individuals. The study also offers suggestions on how interoception-based interventions can be utilized in clinical practice. Such therapies help individuals form healthier bonds with both themselves and others.

(John Wiley and Sons Ltd, 2025-12-29) Eroğlu, Günet; Harb, Mhd Raja Abou
Dyslexia, impacting children's reading skills, prompts families to seek cost-effective neurofeedback therapy solutions. Utilising machine learning, we identified predictive factors for dyslexia classification. Employing advanced techniques, we gathered 14-channel Quantitative Electroencephalography (QEEG) data from 200 participants, achieving 99.6% dyslexic classification accuracy through cross-validation. During validation, 48% of dyslexic children's sessions were consistently classified as normal, with a 95% confidence interval of 47.31 to 48.68. Focusing on individuals consistently diagnosed with dyslexia during therapy, we found that dyslexic individuals exhibited higher theta values and lower beta1 values compared to typically developing children. This study pioneers machine learning in predicting dyslexia classification factors, offering valuable insights for families considering neurofeedback therapy investment.

Deterrents affecting consumers’ organic product purchase
(International Journal of Economics, Commerce and Management, 2020-10) Yarman Ak, Anda; Teker, Dilek
Organic agriculture is becoming an important factor of the economy as years go by and as the awareness on the subject increases among consumers. Although the sector is very promising, the demand is still very low. The value added to be obtained by organic agriculture can be a strong factor of the economy, especially on local basis. Therefore consumers’ purchase behaviors must be examined thoroughly to figure out how the demand can be increased. This study is, hence, focused on the deterrents that prevent consumers to purchase organic foods. An online survey is employed to a sample size of 556 respondents out of 543 were selected based on answering all questionnaire. Two different question set is employed to buyers and nonbuyers to depict the reasons of buying and not buying organic food. This study demonstrates the deterrents for non buyers. The replies given to the hypothesis specific questions are tested by chi-square test. Regarding the outputs, the main deterrents for buying organic food is the lack of packaging and trust in the authenticity of the seller. However, cosmetic concerns are not examined as one of the deterrent for a buy decision. For elimination of these deterrents can convince the consumers to purchase organic foods, which in consequence increase the demand and cause value added for local economy.

(Ms. M. B. Mondal, Ph.D., 2022-09-26) Teker, Suat; Teker, Dilek; Orman, Irmak
This analytical study examines the evolution of digital payment systems and the use by financial institutions and fintech companies in line with the changing user needs, along with the evolutionary developments in information technologies. It also makes a comparative analysis of digital payment platforms that are popularly used all over the world, e.g. PayPal, GooglePay, Wise. The introduction of the first ATM in 1967, the first contactless credit card payment in 1999, the introduction of blockchain in 2009, the emergence of GoogleWallet in 2011 and the introduction of Visa Click-topay in 2020 may be defined as the milestones of digital payment systems. Digital payment systems can be broadly classified as smart cards, online payments, mobile applications, blockchain transfers and biometric authentication. All payment systems in the world are generally shaped according to user needs. The exponential growth of e-commerce and the increasing influence of market regulators also contribute to shaping the future of payment systems. A decentralized monetary management is envisioned by the transition to a cashless economy, the emergence of new online financial institutions, and the adoption of blockchain and cryptocurrencies. It is concluded that the evolution of digital payment systems will expand convenience, refund, convergence, cross-border and time limitless transaction. With the increasing adoption of digital payment systems by all spenders, there is a clear transition towards a cashless economy. The current arguments in academic and professional platforms about the future of digital systems predict that by the 2050s, physical money will be completely out of circulation and these currencies will be replaced by virtual currencies that can easily be transferred over number of digital platforms.

Amaç: Bu çalışma, annelerin mükemmeliyetçiliğinin, annelerin ebeveynlik stilleri ile çocukların içselleştirme ve dışsallaştırma davranış problemleri arasındaki ilişkide aracılık rolünü incelemeyi amaçlamaktadır. Gereç ve Yöntem: Örneklem, 3-6 yaş arası çocukları olan 271 anneden oluşmaktadır. Katılımcılardan sosyodemografik bilgi formu, Ebeveyn Tutum Ölçeği, Hacettepe Ruhsal Uyum Ölçeği ve Çok Boyutlu Mükemmeliyetçilik Ölçeğini doldurmaları istenmiş ve veriler çevrimiçi olarak toplanmıştır. Bulgular: Çalışmanın ana hipotezini test etmek için yapılan analiz bulgularına göre demokratik ebeveynlik, içselleştirme (b=-0,117, p<0,05) ve dışsallaştırma (b=-0,076, p<0,05) davranış problemlerini negatif yönde yordamıştır. Bu ilişkilerde annenin kendine yönelik mükemmeliyetçiliği (KYM) ve sosyal olarak belirlenen mükemmeliyetçilik (SBM) aracılık etmemiştir. Otoriter ebeveynlik, içselleştirme (b=0,046, p<0,05) ve dışsallaştırma (b=0,049, p<0,05) davranış problemleriyle pozitif yönde ilişkilendirilmiş ve bu problemler üzerindeki etkilerinde KYM ve SBM aracılık rolü üstlenmemiştir. Buna karşın, aşırı korumacı ve izin verici tutumlar bu davranış problemlerini anlamlı bir şekilde yordamamıştır. Ayrıca, annelerin KYM’nin, aşırı korumacı ve izin verici ebeveynlik tutumları ile içselleştirme ve dışsallaştırma davranış problemleri arasındaki ilişkide aracılık etkisi olmadığı bulunmuş; ancak SBM’nin aşırı koruyucu ebeveyn tutumu ile içselleştirme [b=0,017, standart hata (SH)=0,009, güven aralığı (GA): (0,003, 0,038)] ve dışsallaştırma [b=0,012, SH=0,007, GA: (0,001, 0,029)] davranış problemlerinde ve izin verici ebeveyn tutumu ile içselleştirme davranış problemi [b=0,013, SH=0,008, GA: (0,000, 0,033)] arasında aracılık etkisinde bulunduğu görülmüştür. Sonuç: Bu çalışma, ebeveynlik tutumları ve özelliklerinin çocukların ruh sağlığı üzerindeki önemli rolünü vurgulamakta, ebeveynlerin etkili ve olumlu ebeveynlik yaklaşımlarını benimsemeleri için pratik müdahalelerin gerekliliğini belirtmektedir.
Performance outcomes of supply chain management practices: evidence from Pakistan's fan manufacturing SMEs
(University of Novi Sad, 2025-12-01) Akbay, Ümmühan; Hafeez, Muhammad Salman
This study examines the impact of supply chain management practices on the organization’s marketing and financial performance. We present the results of a survey conducted with 100 Pakistani fan manufacturing firms. Statistical analysis reveals that the industry struggles with information sharing and joint operations within the supply chain. PLS-SEM analysis of the survey data shows that supply chain performance is significantly correlated with organizational performance. Both customer and supplier relationship management have positive and significant effects on the performance of the supply chain and the organization. However, the impact of customer relationship management is stronger as its path coefficient is greater. Additionally, although internal supply chain management also impacts both supply chain and organization performance positively, the impact is slightly short of being statistically significant. This study contributes to the supply chain management literature by providing empirical evidence from an understudied manufacturing sector from a developing country.

Renewable electricity consumption and economic growth: a cross-income panel ARDL analysis with implications for energy transition
(İstanbul Okan Üniversitesi, 2025-06-02) Brown, Mustapha Abekah; Taşbaşı, Aslı
The transition to renewable energy and the corresponding use of electricity generated from renewable sources is an inevitable solution that must be adopted to mitigate the effects of the climate crisis. The extant literature on the energy-economic growth nexus present mixed findings – some studies suggest the existence of a relationship while others find no significant relationship. Nevertheless, a growing number of recent studies provide evidence of an existing relationship. This study employs the panel ARDL techniques PMG, MG and DFE to investigate the short-run and long-run dynamics between renewable electricty consumption (RELC) and economic growth over the period 2000-2022 across 48 countries classified by income level. The results clearly indicate that the use of green electricity has a positive effect on economic growth across all income levels, albeit with varying magnitudes. Findings of the study provide particularly encouraging empirical evidence for a green transition in developing countries, underscoring the need for more attention to the unique challenges and opportunities faced by these economies.
Evaluation of password hashing competition finalists: performance, security, compliance mapping, and post-quantum readiness
(Karyay Karadeniz Yayımcılık Ve Organizasyon Ticaret Limited Şirketi, 2025-11-15) Ulutaş, Erdem; Çeliktaş, Barış
Password hashes and key derivation functions (KDFs) are central to authentication and cryptographic security schemes crafted to defend user credentials from brute-force attacks and unauthorized access. Password hashing algorithms, for example PBKDF2, bcrypt, or scrypt, are very popular today, but are lacking in the face of modern hardware acceleration, parallel processing, and advanced cryptanalytic attacks. To contest these shortcomings, the Password Hashing Competition (PHC) was started in 2013 and had 22 candidates for functions for hashing passwords. After thorough evaluation, 9 finalists were selected based on how secure, fast, memory-friendly, flexible, and efficient these functions were. This study evaluates the nine PHC finalists—Argon2, battcrypt, Catena, Lyra2, MAKWA, Parallel, POMELO, Pufferfish, and yescrypt—through survey findings and performance benchmarks. We have evaluated these functions from an architectural standpoint and studied their security features, memory hardness, performance tradeoff, and practical usage. We also compare these finalists with traditional password hashing functions to highlight their advantages and limitations. We also investigate the post-quantum assumption for password hashing – the effectiveness of these functions against quantum assaults, their position in a new cryptography set, and the role of peppering as an additional security measure. In addition, we perform a comprehensive compliance mapping of the PHC finalists against major global standards and regulations such as NIST SP 800-63B, OWASP ASVS, PCI DSS, GDPR, KVKK, and ISO/IEC 27001, highlighting their practical suitability for secure deployment in regulated environments. Finally, we provide usage recommendations for these functions for web authentication, KDFs, and embedded platforms. This paper serves as a reference for researchers, developers, and security engineers, while also introducing a complianceaware, post-quantum-ready framework that bridges cryptographic design with regulatory and deployment needs.
Failure management and analysis of medical devices
(Karyay Karadeniz Yayımcılık Ve Organizasyon Ticaret Limited Şirketi, 2025-11-15) Salman, Farah; Çepni, Selden
Medical device failure management is essential for upholding patient safety and healthcare quality standards. However, existing approaches to analyzing and classifying recalls often lack precision, obstructing the identification of root causes and the implementation of effective mitigation strategies. This study proposes a flowchart to enhance the analysis and classification of medical device recalls, with a specific emphasis on addressing software-related failures. The primary aim is to gather extensive data from the Food and Drug Administration's recall database, encompassing various attributes such as device specifications, recall reasons, severity levels, and manufacturer details. By combining manual review processes with advanced classification techniques, the project aims to develop a vigorous and scalable approach to recall classification. The accuracy and reliability of these techniques will undergo rigorous evaluation, contributing to advancements in recall management practices and regulatory oversight. Through this combined approach, the flowchart ensures that the device undergoes thorough evaluation and risk mitigation measures, thereby minimizing potential risks to patient safety and regulatory compliance. Outcomes include the establishment of an accurate integrated flowchart that enhances the understanding of device safety, facilitates proactive risk mitigation strategies, and improves regulatory compliance. Additionally, study findings will inform the development of engineering standards, quality control processes, and ethical guidelines within the medical device industry, ultimately leading to improved patient safety, environmental sustainability, and economic benefits.
An analysis of enterprise-level cloud transition barriers within the Technology-Organization-Environment (TOE) framework and strategic solution proposals
(Gazi Üniversitesi, 2025-10-31) Çeliktaş, Barış; Birgin, Berat; Tok, Mevlüt Serkan
Enterprise-level transitions to cloud service providers are frequently delayed or disrupted due to the multilayered nature of technical, organizational, and legal barriers. This study classifies these obstacles within the TechnologyOrganization-Environment (TOE) theoretical framework and provides a comprehensive analysis. Methodologically, a triangulated data source approach was adopted, combining systematic literature review, the 2025 Flexera Cloud Report, and Cloud Adoption Framework (CAF) documentation from major providers such as AWS, Azure, and Google Cloud. Findings indicate that technological barriers particularly cryptographic complexity, cost unpredictability, and weak system integration, are the most dominant. These barriers were visually modeled, and the structural interdependencies among five core cryptographic components (key management, secure computation, algorithm selection, access control, and regulatory compliance) were illustrated through a flow diagram. By aligning FinOps and compliance-oriented solution strategies with the TOE framework, the study offers a strategic roadmap for decision-makers and cloud architects planning cloud adoption. It links conceptual models to applied practices, providing structured support for organizations seeking to mature their cloud strategy.
