Transformational and transactional leadership in ambidexterous innovation: exploratory and exploitative outcomes
(Emerald Publishing, 2025) Hiziroğlu, Mahmut; Gümüş, Abdülkadir; Özer, Yağmur
Purpose - The research on the relationship between leadership styles and innovation behaviors, particularly exploratory and exploitative innovation, remains inconsistent and underdeveloped. To address this gap, this study aims to investigate the influence of transformational and transactional leadership styles on exploratory and exploitative innovation, while also examining the moderating effects of organizational factors, specifically firm size and organizational age. Design/methodology/approach - This study employs a quantitative research design, with the sample of firms that have at least ten employees. A total of 762 valid responses were collected through surveys. The data were analyzed using hierarchical regression analysis. Findings - The results reveal that transformational leadership positively influences exploratory innovation but negatively affects exploitative innovation, whereas transactional leadership positively influences both types. Notably, contrary to prior research, transactional leadership also enhances exploratory innovation. Firm size moderates these relationships in an inverted U-shape: transformational leadership fosters exploratory innovation in small and large firms and supports exploitative innovation in medium-sized firms. A similar pattern emerges for transactional leadership. Additionally, younger firms exhibit a stronger preference for exploratory innovation. Research limitations/implications - This study is limited to Turkish firms, which may restrict the generalizability of the findings. It relies on perceived innovation behavior rather than objective metrics and does not consider factors like sectoral or cultural differences. The cross-sectional design also limits causal inferences, indicating the need for longitudinal or experimental research to explore temporal dynamics. Practical implications - From a practical standpoint, this study highlights the critical role of leadership in shaping innovation behaviors, offering insights for organizations of different sizes and ages. It demonstrates how leadership styles can be leveraged to foster ambidextrous innovation, providing a tailored approach for leaders to enhance innovation while considering key contextual factors affecting leadership effectiveness. Originality/value - This study enhances understanding of how leadership styles influence the balance between exploratory and exploitative innovation in Turkish firms, emphasizing the moderating roles of firm size and age. It also challenges the conventional view that transformational and transactional leadership are exclusively linked to specific innovation types, offering a more nuanced perspective on the role of leadership in fostering ambidextrous innovation.
Examining the Relationship Between Social Media Addiction, Fear of Missing Out, Loneliness, and Life Satisfaction Among Youth: A Cross-Sectional Study
(Serbian Psychologists, 2026) Işık, Nurten Arslan; Keleş, Dilsa Azizoğlu; Sandıkçı, İrem Nur; Kotyk, Taras; Okanlı, Ayşe
This cross-sectional study examines the relationships among social media addiction, fear of missing out (FoMO), loneliness, and life satisfaction among young adults. Data were collected from 700 participants aged 18-29 years via an online survey administered between May and June 2024. Validated scales were used to assess key variables: the Bergen Social Media Addiction Scale, the Fear of Missing Out Scale, the UCLA Loneliness Scale, and the Satisfaction with Life Scale. Structural Equation Modeling revealed that life satisfaction was positively associated with loneliness. Social media addiction was strongly associated with FoMO, while FoMO had an indirect negative effect on life satisfaction through social media addiction. These findings shed light on the underlying mechanisms between social media addiction, FoMO, loneliness, and life satisfaction. Such insights can provide significant implications for developing interventions (e.g., digital well-being programs) to help young adults manage their social media use more effectively. Promoting mindful and balanced social media engagement may contribute to enhancing life satisfaction and overall mental well-being.
A Comparative SWOT Analysis of Hospital Management Protocols for Radiation Accidents in Türkiye and Japan
(2025) Kolçak, Dilek
Background: The situation in which radiation emerges uncontrollably is referred to as a radiation accident. Radiation accidents constitute emergencies that can have severe impacts on public health. Therefore, it is of critical importance for hospitals providing healthcare services to be adequately prepared for such incidents. Materials and Methods: This study aims to compare the hospital management protocols for radiation accidents in T & uuml;rkiye and Japan using the strengths, weaknesses, opportunities, threats (SWOT) analysis method. As a country that has experienced a radiation accident, Japan's postincident developments are compared with T & uuml;rkiye's current situation. The study first examines the radiation safety regulations, healthcare policies, and hospital management strategies of both countries. While T & uuml;rkiye has established general protocols under the Hospital Disaster and Emergency Plan (HAP) and for Chemical, Biological, Radiological, and Nuclear (CBRN) incidents, Japan has enhanced its crisis management and emergency response systems following the 2011 Fukushima Nuclear Accident. Within the framework of the SWOT analysis, the strengths and weaknesses of both countries, potential threats, and opportunities for improvement are analyzed in detail. Results and Discussion: This study highlights how T & uuml;rkiye can benefit from Japan's crisis management experience to enhance its preparedness for radiation accidents. The analysis reveals that T & uuml;rkiye has significant shortcomings, particularly in training, drills, and hospital infrastructure. However, its investments in nuclear energy provide opportunities for development through international collaborations. On the other hand, although Japan possesses advanced radiation monitoring systems and extensive experience, it remains under constant threat due to its high concentration of nuclear power plants and exposure to natural disasters. Conclusion: To prevent radiation accidents, it is recommended to develop a hospital management model based on international standards. Additionally, effective intervention strategies should be formulated through the collaborative decision-making of hospital administrators, healthcare professionals, and policymakers to ensure a comprehensive response to radiation accidents.
Malocclusion as a Cause of Temporomandibular Joint Disorders
(2025) İşçi, Kemal Devrim
The jaw and skull are joined at the temporal mandibular joint (TMJ), a synovial joint. You can find these two joints directly in front of your ears. Each joint comprises the mandibular condyle, the temporal bone’s articular tubercle, and an articulating disk. Allowed motions include lateral, vertical, and horizontal movement, protrusion, and retrusion. The complex motions of chewing, speaking, and generating facial emotions are made possible by this joint and the muscles that link to it. The joint pain and dysfunction that affect the jaw joint are known as temporomandibular disorders (TMDs) or TMJ syndrome. Myalgias, myofascial pain, arthralgia, disk displacement disorders, degenerative joint disease, subluxation, and 11 other pain-related and intra-articular TMJ diseases have been found by an international group. © 2025 Springer Nature Switzerland AG.
Treatment of a Class II, Division 1 Malocclusion and Ectopic Canines with Invisalign Mandibular Advancement and the Bootstrap Technique
(2025) Taslan Ceylanoğlu, Sinem; Ceylanoğlu, Cenk; Alcan, Toros
In a growing patient, a Class II, division 1 malocclusion is often treated by inducing supplementary mandibular growth with functional appliances. As Toth and colleagues reported, the correction is achieved through a combination of normal growth and mandibular skeletal and dento alveolar changes. 1 The proportion of skeletal to dental effects is determined by the timing of treatment,2, 3 the mode of mandibular advancement,4, 5 and the type and rigidity of the appliance.3, 6-8 © 2025 JCO, Inc.
