The Impact of Social Media Based Advice on Health Behaviors in Digital Health Communication
(Taylor Francis, 17.06.2026) Öngel, Volkan; Uluğ Yurttaş, Özge; Bozkurt Ateş, Gözde; Gümüşboğa, Yağmur
The growing visibility of social media influencers has increased interest in their role in shaping health beliefs and behaviors. While prior research has largely focused on message characteristics or direct behavioral outcomes, less attention has been given to the conditions under which influencer-based health messages are interpreted and translated into action. This study conceptualizes influencer-based health communication not as a direct persuasive force, but as a conditional communication process. Drawing on Uses and Gratifications Theory and the Health Belief Model as interpretive frameworks, it examines how individuals engage with health-related influencer content, how such engagement relates to health perceptions, and how digital health literacy shapes message interpretation.
Survey data from social media users were analyzed using Firth’s penalized logistic regression to address the rarity of influencer-driven health behavior. Findings indicate that, despite high levels of exposure to influencer-based health content, the translation of such exposure into health-related action remains limited. Exposure to health content significantly increases the likelihood of influencer-driven behavior, whereas higher digital health literacy reduces this likelihood, suggesting a protective effect. Additionally, perceived commercial intent decreases the probability that influencer recommendations lead to action.
By distinguishing between engagement and behavioral change, this study reframes influencer effects as conditional outcomes shaped by motivations, perceptions, and interpretive competencies. It contributes to health communication literature by moving beyond linear persuasion models and highlighting the critical role of digital health literacy. The findings also offer practical implications for strengthening individuals’ ability to critically evaluate health information in digital environments.
The Role of Kapok Fiber in Modifying the Strength and Thermal Properties of Cement and Silica Fume Mortars: An Experimental Approach
(Hrčak, 30.04.2026) Susurluk, Gülşah; Sarıkaya, Hakan; Bostancı, Levent
Utilization of natural fibers into cementitious mixtures is gaining attention for their recyclability, renewability, sustainable features and other environmental benefits. Among varied natural fibers, kapok fiber (KP), a kind of lightweight and renewable natural fiber deserves attention for its ability to improve the strength and thermal insulation features of sustainable mortars and application of KP fiber in cementitious mixtures is still very limited. This research examined the impact of KP fiber on the strength features, pore structure, thermal insulation performance, and microstructure of ordinary Portland cement (OPC) and silica fume (SF) mixtures. The results indicated that KP incorporation at a content of 1% by cement weight leads to insulation enhancement up to 19% with 9.50% flexural strength gain. A linear regression analysis was conducted between pore structure characteristics and the determined strength/conductivity values to reveal the impact of KP fibers in the cement matrix. KP fiber has considerable potential to play a role in structural cementitious material design as a sustainable material.
Adapting and validating the FOODLIT-Tool in Turkish: a psychometric study on food literacy for sustainability
(Cambridge University Press, 03.06.2026) Demir Pulat, Halime; Anılgan Şahin, İrem Nur; Atar, Aslıhan
This study aimed to adapt and validate the FOODLIT-Tool in Turkish to assess sustainable food literacy among Turkish adults. The adaptation addresses a lack of psychometrically validated instruments for measuring food literacy and sustainability-oriented eating behaviours in Turkey.
Design:
A psychometric evaluation was conducted, including forward-translation, back-translation and cultural adaptation steps, followed by expert review for content validation. Construct validity was assessed using confirmatory factor analysis (CFA), and internal consistency was evaluated to ensure reliability.
Setting:
Data collection was conducted online via Google Forms between July and August 2024.
Participants:
A total of 482 participants aged 18 to 65 years residing in Turkey voluntarily completed the Turkish version of the FOODLIT-Tool, along with a general information form and the Sustainable and Healthy Eating Behavior Scale.
Results:
CFA results demonstrated an acceptable model fit (χ2/df = 3·67, CFI = 0·91, RMSEA = 0·07). Cronbach’s α values ranged from 0·60 to 0·91 across the sub-dimensions, indicating adequate to excellent internal consistency. Significant positive correlations were found between FOODLIT subscales and sustainable eating behaviours. Women scored significantly higher in culinary competence, production quality and environmental awareness.
Conclusions:
The adapted Turkish version of the FOODLIT-Tool demonstrates satisfactory validity and reliability for evaluating food literacy and sustainable dietary practices among Turkish adults. The scale serves as a useful assessment tool for future research and intervention studies focusing on sustainable nutrition. Further validation using representative samples and longitudinal designs is warranted before its application in public health or policy-making contexts.
Real time adaptive control of photovoltaic battery systems: Integrated management of state of charge, voltage regulation, and irradiance fluctuations
(ScienceDirect, 31.01.2026) Dagal, İdriss
This study develops a real-time adaptive control strategy for photovoltaic (PV) battery systems that simultaneously optimizes state of charge (SOC) management, voltage regulation, and irradiance response. Combining adaptive pulse-width modulation (PWM) based maximum power point tracking (MPPT) with closed-loop SOC balancing and dynamic proportional–integral (PI) control, the system achieved 94.2% average energy conversion efficiency (15% improvement over conventional methods) while maintaining SOC stability within ±0.8% during 80% irradiance variations and reducing voltage ripple to <1.5 Vpp. Experimental validation on a 1 kW PV‑lithium-ion battery system demonstrates superior performance under realistic conditions, offering enhanced battery lifespan and grid stability for commercial-scale renewable energy applications. The integrated control architecture presents a scalable solution for addressing key challenges in PV battery system operation under dynamic environmental fluctuations.
Disaster management in Türkiye: a qualitative study on healthcare professionals
(Sprınger Nature, 25.04.2026) Erküvün, Kübra Sezen; Mutlu, Hatice; Türkoğlu, Mesut Can
Background
Disasters pose complex challenges that extend beyond immediate emergency response, requiring well-coordinated, resilient, and health-centered disaster management systems. In disaster-prone countries such as Türkiye, understanding how health services, particularly specialized medical rescue teams, function in real disaster settings is critical for identifying systemic gaps and improving preparedness, coordination, and response capacity. The aim of this study is to examine the managerial and organizational challenges encountered in disaster management processes based on the experiences of UMKE personnel who have served during various disasters in Türkiye, and to derive implications for strengthening disaster preparedness and response capacity.
Methods
The study was conducted using a qualitative research design. In-depth interviews were carried out with healthcare professionals who participated in disaster response. The data were analyzed using thematic analysis, and the findings were categorized into five main themes: shortages of logistics and equipment; working conditions and training; social awareness; lack of coordination, communication, and organization; and institutional structure and local empowerment.
Results
The findings revealed that road damages hindered transportation and that alternative transportation plans were inadequate. Disaster training were not fully adapted to field conditions. Public disaster literacy was found to be low. Insufficient coordination and communication disrupted interventions. In addition, the study identified psychosocial support, community-based education, and institutional capacity building as critical components of effective disaster management.
Conclusions
This study was designed to capture the personal perspectives of healthcare professionals who directly confronted disasters and gained first-hand experience of related processes. Therefore, it provides a unique contribution by presenting a disaster management framework through the lens of healthcare professionals and by highlighting areas in need of improvement for policymakers in this field.
