Öğe Türü:Öğe, An integrative nature-based planning model for sustainable and resilient environments(Springer Nature, 2026) Çınar, Hande Sanem; Yılmazsoy, BurakDespite increasing policy recognition of Nature-based Solutions (NbS), a persistent gap remains between conceptual sustainability frameworks and reproducible, perfor mance-based planning applications supported by spatial modeling and ecosystem service quantification. This study addresses this gap by developing a spatially explicit NbS planning and evaluation framework for the Shenks Property along the Severn River within the Chesapeake Bay watershed, Virginia, USA. The research integrates GIS-based hydrological modeling, ecosystem-service assessment using the InVEST platform, and resilience evaluation under NOAA 2050 intermediate sea-level rise projections.Multiple spatial datasets, including land-use/land-cover classifications, LiDAR-derived elevation models, soil characteristics, biodiversity inventories, and tidal observations, were analyzed within an integrated analytical workflow. Results indicate measurable ecological and hydrological improvements under NbS-based scenarios. Predictive simulations demonstrate an approximately 40% (± 5%) reduction in annual surface runoff and an approximately 20 m retraction of projected flood boundaries under future sea-level rise conditions. Carbon-storage capacity increased by 18–24%, while habitat-quality index values improved by 15–22% within rehabilitated wetland zones. Increased vegetation density additionally contributed to localized microclimatic cooling of approximately 2–3 °C. The findings demonstrate that NbS can simultane ously support climate adaptation, ecological restoration, and long-term spatial resil ience while potentially reducing maintenance demands relative to conventional gray infrastructure systems. Methodologically, the study advances the operationalization of NbS by integrating ecosystem-service modeling, hydrological simulations, and adap tive spatial planning into a transferable performance-based planning framework. How ever, while the study offers robust predictive insights, its findings are based on mode ling and scenario-based simulations. Therefore, long-term post-occupancy monitoring is essential to validate ecological performance and system resilience.Öğe Türü:Öğe, Bot faaliyetleri yoluyla haksız rekabet ve elektronik ticaret platformunun bot saldırılarından sorumluluğu(Aristo Yayınevi, 2026) Pehlivanoğlu, Murat CanBu çalışmada bot saldırılarının işletmeler arasındaki rekabeti bozan bir haksız rekabet eylemi olarak değerlendirilip değerlendirilemeyeceği incelenmekte ve yine bu çerçevede üzerinden saldırı gerçekleştirilen elektronik ticaret platformunun hukuki sorumluluğuna değinilmektedir.Öğe Türü:Öğe, Türk dış politikasında hibrit bir araç: Sert güç, yumuşak güç ve savunma sanayii üçgeninde modern deniz gücü diplomasisi(Marmara Üniversitesi, 2025) Özel, MesutBu çalışma, 2000 sonrası dönemde Türkye'nn deniz gücü kullanımında niteliksel bir dönüşüm gerçekleştirdiğin ve klasik "gambot diplomasisi'ni aşan hibrit bir "Modern Denz Gücü Diplomasisi modeli geliştirdiğini öne sürmektedir. James Cable'ın gambot diplomasisi ve Joseph Nye'ın yumuşak güç teorilerini, Rowlands'ın paydaş analiz ve güç dönüştürme kapasitesi kavramları ışığında sentezleyen çalışma, savunma sanayii diplomasisini sistematik bir üçüncü ayak olarak entegre eden yeni bir analitik çerçeve sunmaktadır. Üç temel bileşen stratejik sinerji içinde birleştiren bu model: (1) Sert Güç (asker caydırıcılık ve zorlayıcı diplomasi), (2) Yumuşak Güç Projeksiyonu (insan diplomasi, itibar inşası ve iş birliği ve (3) Savunma Sanayii Diplomasisi'nden (yerli teknolojik kapasitenin nüfuz ve ortaklık aracı olarak sergilenmesi) oluşmaktadır. Modelin etkinliği ve sürdürülebilirliği, Soğuk Savaş sonrası stratejik özerklik arayışına dayanan yerli savunma sanayii kapasitesindeki köklü büyümeyle doğrudan ilişkilidir. Bu dönüşüm, Türk Donanması'nı geleneksel kıyı koruma rolünden, proaktif bir küresel aktör konumuna taşımıştır. Çalışma, modelin operasyonel işleyişin nitel vaka analizler üzerinden incelemektedir: Türkye'nn Libya müdahalesi ve deniz yetki alanları mutabakatı, Türk Denz Görev Grupları'nın küresel seferler le Somal ve Katar'dakiler üs stratejsi. Analiz, bu hibrit modelin Türkye'yi gambot diplomaisisin tarihsel mağduru konumundan, 21. yüzyıl deniz devlet aklında kilit bir aktör konumuna taşımada etkili olduğunu göstermektedir. Çalışma, literatüre yen bir analitik çerçeve önermek ve bu model ampirik olarak detaylandırmak suretiyle katkı sunmaktadır. Bununla birlikte, modelin uzun vadeli başarısı azalan getiriler, algı yönetim zorlukları, dengeleyici koalisyon riskler ve taktik kazanımları kalıcı diplomatik sonuçlara bağlayacak stratejlerin geliştrilmesi gerekliliği gibi zorluklarla karşı karşıyadır. Nihia başarı, sert gücü derinleşmiş diplomatk angajman ve yumuşak güç kapasitesiyle destekleyen kapsayıcı br stratejk vizyona bağlıdır.Öğe Türü:Öğe, Emergency department utilization in patients with chronic spontaneous urticaria followed at a tertiary referral center: A retrospective cross-sectional study(Wiley, 2026) Caf, Nazlı; Türkoğlu, Zafer; Kırsoy, Erişcan Melih; Koçak, Seyfettin Mahir; Atsü, Ayşe Nilhan; Eker, Hediye; Özkoca, DefneBackground: Chronic spontaneous urticaria (CSU) frequently prompts emergency department (ED) visits, but few studies have characterized this utilization in a defned dermatology cohort under contemporary anti-IgE therapy. Objective: To quantify ED utilization, identify factors associated with prior ED visits, and describe the pattern of ED-initiated dermatology consultation in adult CSU patients at a tertiary referral center. Methods: Retrospective cross-sectional analysis of 195 adult patients with physician-diagnosed CSU at a single tertiary der matology clinic between June 1,2025, andDecember31,2025.ThreeoperationalEDutilization rates wereestimated. Patients with at least one prior ED visit were compared with patients without, and a multivariable logistic regression model was constructed. Results: Median age was 43years (Q1–Q3: 36–51); 66.2% were female; angioedema was reported in 24.1% and omalizumab prescribed in 97.9%. The ED served as the initial point of contact in 5.1% (95% confdence interval [CI]: 2.8%–9.2%); 45.1% (95% CI: 38.3%–52.1%) had any prior ED visit and 26.2% (95% CI: 20.5%–32.7%) had recurrent visits. Among ED users, antihistamines were administered in 93.2% andsystemic corticosteroids in 59.1%, while ED-initiated dermatology consultation was documented in only 8.0% (95% CI: 3.9%–15.5%). In multivariable analysis, concomitant angioedema was independently associated with prior ED utilization (adjusted OR: 3.99, 95%CI:1.93–8.69, p < 0.001);identifabletrigger wasinverselyassociated (adjustedOR:0.36, 95%CI: 0.14–0.88, p = 0.025). Conclusions: Even though omalizumab had been prescribed in 97.9% of the patients, almost half had attended the ED and consultation occurred in fewer than one in ten ED users. Concomitant angioedema independently predicts ED utilization, and ED encounters represent a missed integration point in CSU longitudinal care.Öğe Türü:Öğe, The overlooked biochemical pathway: How insulin resistance (HOMA-IR) modulates "metabolic masking" of prostate-specific antigen separately from body mass index(Springer Nature, 2026) Eren, Murat Tuğrul; Özveri, HakanBackground Conventional prostate cancer screening profiles rely heavily on static serum prostate-specific antigen (PSA) thresholds, consistently overlooking the confounding impacts of the modern metabolic syndrome epidemic. This study aimed to isolate and quantify the long-term longitudinal impact of insulin resistance (HOMA-IR) and Body Mass Index (BMI) on serum PSA levels. Materials and methods We retrospectively evaluated 9095 routine annual screening records from 5,846 asymptomatic male subjects (2016–2026) with concurrent clinical data for PSA, HOMA-IR, BMI, and total testosterone. Linear Mixed-Effects Models with subject-specific random intercepts were constructed to rigorously account for intra-subject correlations across consecutive annual follow-up visits. Results Multi-variable longitudinal analysis demonstrated that while BMI exhibited a strong downward trend on baseline biomarkers (per-unit decrease of 0.018 ng/mL (p = 0.057), elevated HOMA-IR served as a statistically significant, independ ent biochemical marker inversely associated with serum PSA (p = 0.042). Crucially, categorical stratification revealed a highly significant, non-linear biomarker collapse: subjects in the highest cumulative metabolic burden quadrant (concurrent BMI ≽35 kg/m2 and HOMA-IR > 3.0) exhibited a profound 34.8% reduction in age-adjusted serum PSA concentrations compared to metabolically healthy, normal-weight counterparts (p < 0.001). Conclusions "Metabolic masking" of serum PSA is a complex, two-pronged process characterized by physical hemodilution via tissue mass and cellular transcription-level suppression via chronic hyperinsulinemia. Transitioning away from simplistic weight-based corrections in clinical preventive screening guidelines along with systematic integration of insulin resistance profiles into individualized urological risk stratification may help eliminate this critical diagnostic blind spot.
