Associations of Shift Work and Chronotype with Physical Activity and Eating Behaviors in Adult Women
(Multidisciplinary Digital Publishing Institute (MDPI), 2026) Turan, Nisanur; Dumlupınar, Berrak; Gülüş Oymak, Hasret; Ertem, Rabia Ela; Aydın, Bekir Kürşat; Karamollaoğlu, İrem; Öztürkcan, Arda
Background: Shift work and chronotype may influence dietary habits, physical activity, and eating behaviors. However, research examining the combined associations of shift work and chronotype with these behaviors in women is limited. This study examined these associations, together with anthropometric outcomes, among women attending an obesity counseling center. Methods: A cross-sectional study included 190 women aged 18–64 years (mean age: 33.31 ± 7.87 years) attending an obesity counseling center in Istanbul. Sociodemographic data, dietary habits, work schedules and behavioral data were collected using structured questionnaires, whereas anthropometric measurements were obtained using standardized procedures. Chronotype, physical activity, and eating behaviors were assessed using the Morningness–Eveningness Questionnaire (MEQ), International Physical Activity Questionnaire (IPAQ), and Dutch Eating Behavior Questionnaire (DEBQ). Statistical analyses included chi-square tests, parametric-nonparametric group comparisons, and multivariable linear and logistic regression models. Results: Compared to fixed-schedule workers, shift workers had more frequent meals (77.9% vs. 59.6%; p = 0.007, V = 0.195) and breakfast (51.2% vs. 16.3%; p < 0.001,V = 0.371) skipping. Participants with obesity had higher emotional eating, external eating, total DEBQ, and total meal-number values than the other BMI groups. Chronotype scores varied according to age, smoking, alcohol consumption and occupational factors, but were not directly correlated with anthropometric measurements. Conclusions: Shift work was associated with irregular eating habits and altered eating behaviors. These findings should be interpreted with caution because the cross-sectional, single-center design limits causal inference and generalizability. To better understand the relationship between chronotype, lifestyle, and obesity-related behaviors, as well as to develop effective interventions, larger prospective studies are needed.
Reliable Interpretation of Extreme-Heat Energy Response for Sustainable Campus Management: Baseline, Calendar, and Chilled-Water Metering Controls
(Multidisciplinary Digital Publishing Institute (MDPI), 2026) Cihangir, Cenk; Özyılmaz, Lale; Coşkun, Yusuf
Open hourly meter data are often used to infer how buildings respond to extreme heat, but the interpretation can depend on the analytical baseline, institutional calendar, and meter configuration. We examined 60 education and office buildings in the Building Data Genome Project 2 using repeated whole-week validation, temperature-matched placebo tests, 13 academic-calendar definitions, and same-building, common-hour carrier comparisons. A leakage-resistant change-point model that incorporated a previous-day, loadderived operating-regime proxy reduced blocked-validation error relative to a conventional model in 58 of 60 buildings; temperature binning provided no additional predictive benefit after regime control. Recovery-related signals were uncommon: rebound was significant in 2 of 49 eligible buildings, load-shape disruption in 1 of 49, and the 72 h duration diagnostic in 3 of 60. At Fox, the BASE calendar supported term and break comparisons through 39–42 ◦C, but neither building-use group differed significantly after false-discovery-rate adjustment; estimates above 42 ◦C were inconclusive. In the matched sample of 13 education and 10 office buildings, no electricity-only, chilled-water-only, or weighted specification provided robust evidence of a between-group difference. Across 99 combinations of carrier weight, normalization, and temperature bin, every 95% interval included zero. Reliable campus benchmarking therefore requires out-of-sample baseline assessment, explicit calendar sensitivity, common-hour meter matching, and carrier-specific uncertainty reporting before building-use rankings or resilience-related interpretations are made.
Individual Resilience and Protective Mental Health: The Role of Psychological Resilience
(İstanbul Gelişim Üniversitesi Yayınları / Istanbul Gelisim University Press, 2026) Elkin, Nurten; Soydan, Ayşe Mücella
This review examines the concepts of psychological resilience and preventive mental health, and their roles in individuals' mental health protection and improvement processes. Psychological resilience represents individuals' capacity to adapt to stressful and challenging life conditions, while the preventive mental health approach aims to strengthen individuals' internal resources and environmental support systems. Literature findings show that psychological resilience is effective not only in preventing mental health problems but also in increasing individuals' life satisfaction and subjective well-being. This highlights the importance of empowering and preventive approaches in addition to risk-focused approaches in mental health practices. It is emphasized that individual characteristics, social support, family, and environmental factors are decisive in the development of psychological resilience; and that the interaction between preventive mental health and psychological resilience plays a crucial role in protecting mental health at both individual and societal levels. The study emphasizes the importance of integrating programs that support psychological resilience into education, work, and community-based mental health services, and highlights the need for longitudinal and experimental studies in future research. This review demonstrates that psychological resilience is a fundamental building block in the preventive mental health perspective and contributes to strengthening mental health at both individual and societal levels.
Understanding International Botanical Tourists’ Travel Motivations: The Role of Plant Diversity and Landscape Attributes in Turkey
(Multidisciplinary Digital Publishing Institute (MDPI), 2026) Çetinkaya, Öznur; Kandemir Altunel, Gizem
Botanical tourism is a growing niche within nature-based travel, yet little is known about tourists who travel specifically to observe plants in their natural habitats. This study addresses this gap by examining the travel motivations of international botanical tourists visiting Turkey through the push–pull framework. A qualitative approach was adopted, and semi-structured interviews were conducted with 56 tourists recruited through a specialist botanical tour operator. Reflexive thematic analysis identified six push factors: biophilia and nature centrality, psychological escape, plant passion and identity, knowledge seeking, transformative experience, and ethical reflection. Five pull factors were also identified: professional guides, endemism, natural landscapes, seasonality, and remoteness and authenticity. The findings show that botanical tourism is an identity-based and knowledge-oriented form of travel in which personal motivations are closely linked to ecological destination attributes. The study extends push–pull theory and offers practical implications for guide training, endemic-route design, phenology-based itineraries, and conservation-sensitive tourism management.
Developing a Climate-Referenced SS–LT Site-Performance Assessment Framework: An Exploratory Five-Case Study of Green-Certified Smart Office Buildings
(Multidisciplinary Digital Publishing Institute (MDPI), 2026) Yılmaz, Ezgi; Akkam, Mehmet Sair
Green-building research has examined energy efficiency and indoor environmental quality in depth, whereas site-related strategies are often represented through aggregate certification outcomes with limited visibility into criterion-level evidence and weighting assumptions. This study develops the Climate-Referenced SS–LT Site-Performance Assessment Framework (CR-SSAF) for an exploratory documentation-based comparison of a combined Sustainable Sites, Location, and Transportation (SS–LT) construct across five green-certified smart office buildings in three Köppen climate zones. Six SS–LT criteria were assessed using a four-level operational rubric, an exact-normalized weighted Site-Performance Index (SSPI), a descriptive Technology Enablement Factor (TEF), ordinal inter-rater agreement analysis, three weighting schemes, and a TOPSIS ranking-concordance check. SSPI values ranged from 2.00 to 2.65. The Af case recorded the highest SSPI in this sample, while the lowest scores occurred where no qualifying project-specific heat-mitigation or green-/openspace evidence could be verified. The first, second, and last ranks remained unchanged across the three weighting schemes, while The Edge and Shanghai Tower were tied under the equal and ecology-sensitive schemes. Because the sample is small and heterogeneous, and does not control for urban form, building scale, infrastructure, certification system, or documentation availability, differences cannot be attributed independently to climate. CR-SSAF is therefore presented as a transparent exploratory workflow, not as a validated climate effects model or as evidence of transferability.
