Öğe Türü: Öğe , Examining Emotional Fatigue and Social Indifference in the New Media Era(IGI Global, 2026) Cansever Bayhan, Ayten BengisuIn the new media era, characterized by constant connectivity and flow of information, individuals experience emotional fatigue alongside social indifference. Relentless exposure to news cycles, social media updates, and digital interactions can desensitize audiences, making it difficult to sustain empathy or build meaningful engagement. Emotional responses may become diluted, replaced by passive consumption or disengagement. This shift raises important questions about how digital environments shape emotional capacity, social responsibility, and the quality of human connection in an age where attention is commodified. Examining Emotional Fatigue and Social Indifference in the New Media Era explores how digital media cultures generate emotional stimulation while producing emotional fatigue and social indifference. It investigates the paradox of the hyper-connected yet detached individual, bringing together interdisciplinary perspectives from media studies, psychology, sociology, cultural studies, and communication. This book covers topics such as ethics and law, social media, and algorithms, and is a useful resource for sociologists, media professionals, psychologists, academicians, researchers, and scientists.Öğe Türü: Öğe , Multifunctional Polyvinyl Alcohol Films Incorporating Hypericum perforatum Essential Oil: Antibacterial Activity and Shape Memory Performance Supported by Molecular Docking(John Wiley and Sons Inc, 2026) Ünlü, NihanThe development of multifunctional antimicrobial materials represents a promising strategy to address the growing challenge ofantimicrobial resistance. In this study, polyvinyl alcohol (PVA) films incorporating Hypericum perforatum essential oil (HPEO)at different concentrations (0.1%–0.3%) were fabricated and systematically characterized. Structural interactions were analyzedby FTIR, while optical transparency and UV-barrier performance were evaluated using UV–Vis spectroscopy. Thermal and ther-momechanical behavior were examined by DSC and DMA, respectively. The incorporation of HPEO induced slight modificationsin hydrogen bonding interactions and produced moderate plasticization effects without introducing additional phase transitions.Shape memory analysis revealed enhanced shape fixity (up to 98.00%) and high recovery ratios (> 95%), indicating improvedtemporary shape stabilization while preserving elastic recovery. Antibacterial evaluation against Escherichia coli ATCC 25922demonstrated concentration-dependent inhibition, with the highest activity observed for the 0.3% formulation. To elucidate po-tential molecular mechanisms, bioinformatics-guided molecular docking was performed against virulence-associated proteins(1WXR, 4MEE, 3EFY, 5WIO). Docking analysis (RMSD = 0.00 Å) revealed strong multi-target binding affinities, particularly forkielcorin, mangiferin, and chlorogenic acid (up to −9.8 kcal/mol). The integration of experimental and computational findingssuggests that HPEO incorporation enables the development of structurally stable, UV-protective, shape-memory active filmswith antibacterial functionality supported by multi-target virulence modulation.Öğe Türü: Öğe , Öğe Türü: Öğe , Lowering Uncertainty for Sustainable Development:Assessing the Effectiveness of Green Innovation(John Wiley and Sons Ltd, 2026) Olanipekun, Ifedolapo OlabisiOne of the fundamental challenges on the path to sustainability is the interruption caused by various uncertainties. This studyexamines how clean energy technology interacts with sustainability uncertainty across different timescales and frequencies, usingdata from March 2013 to March 2025. Wavelet coherence and partial wavelet coherence analyses are used to explore the dynamicrelationships, accounting for the influence of oil futures. The results indicate a dynamic relationship between clean energy technol-ogy and sustainability uncertainty. While clean technology and sustainability uncertainty moved in opposite directions between2014 and 2015, there were positive co-movements from 2017 to 2021. Most changes were driven by clean technology and wereevident only in the short term, whereas movements were nearly synchronized in the medium term, with indications of long-termsynchronization. Therefore, sustainability uncertainty may be triggered by the market signal effect, which causes most short-termdisturbances. However, this relationship is not entirely independent of oil futures, especially in the long term. This suggests that along-term sustainability path is not independent of oil market dynamics. Consequently, long-term sustainability strategies couldbe more effective by leveraging attractive clean technology stock indices to improve sustainable finance.Öğe Türü: Öğe , Existence and Approximate Controllability of Mild Solutions for Hadamard-Type Fractional Systems in Banach Spaces(Indian National Science Academy, 2026) Mesri, Fatima; Abdeljawad, ThabetThis work establishes the approximate controllability of nonlinear Hadamard-type fractional systems with weakly singular logarithmic kernels in Banach spaces. Under suitable assumptions on the linearized control operator and a linear growth condition on the nonlinearity, we prove the existence of a mild solution steering the system from an arbitrary initial state arbitrarily close to a prescribed terminal state. The proof combines Krasnoselskii’s fixed point theorem with refined estimates involving logarithmic convolutions.
