Examining the Antecedents of Sustainable Clothing Purchase Intention Among Generation Z
Get PDFBu araştırma, Z Kuşağı tüketicileri arasında sürdürülebilir giyim satın alma davranışının öncüllerini, gösteriş tüketimi, algılanan tüketici etkinliği, yeşil güven, algılanan yeşil aklama, sosyal medya davranışı ve algılanan bilimsel fikir birliği gibi faktörlere odaklanarak incelemektedir. Araştırmada, Mart 2024 ile Eylül 2024 tarihleri arasında sosyal medya üzerinden dağıtılan Google Formlar ve Atılım Üniversitesi kampüsünde yüz yüze etkileşimler yoluyla toplanan verilerle nicel bir yaklaşım benimsenmiştir. Bu çalışmada amaçlı örnekleme yöntemi kullanılmış ve toplanan veriler, önerilen modeli test etmek için Kısmi En Küçük Kareler Yapısal Eşitlik Modelleme (PLS-SEM) yöntemiyle analiz edilmiştir. Bulgular, gösteriş tüketimi, algılanan yeşil aklama ve toplam sosyal etkinin sürdürülebilir giyim satın alma davranışını önemli ölçüde etkilediğini ortaya koymuştur. Tahmin değişkenleri arasında, gösteriş tüketimi en yüksek etki boyutunu göstermiş ve sosyal statü ile kendini ifade etmenin çevre bilinciyle yapılan tercihleri yönlendirmede önemli bir rol oynadığını vurgulamıştır. İlginç bir şekilde, algılanan yeşil aklama sürdürülebilir satın alma ile pozitif bir ilişki göstermiş ve bu durum, tüketicilerin sürdürülebilir alternatiflerin eksikliği nedeniyle yeşil aklama yaptığı düşünülen markaları destekleyebileceğini öne sürmüştür. Buna karşılık, yeşil güven, algılanan tüketici etkinliği ve algılanan bilimsel fikir birliği doğrudan anlamlı etkiler göstermemiştir, bu da bu faktörlerin etkisinin daha ince veya bağlama bağlı olabileceğini göstermektedir. Bu çalışma, Z Kuşağı'nın sürdürülebilir tüketim davranışını yönlendiren karmaşık motivasyonlar hakkında değerli bilgiler sunmaktadır. Bulgular, bu kuşağı sürdürülebilirlik çabalarına etkili bir şekilde dahil etmek ve moda endüstrisinde stratejiler geliştirmek için sosyal ve psikolojik faktörlerin anlaşılmasının önemini vurgulamaktadır. Anahtar Sözcükler: Sürdürülebilir Giyim, Gösterişçi Tüketim, Sosyal Medya, Yeşil Aklama, Z KuşağıThis research investigates the antecedents of sustainable clothing purchase behavior among Generation Z consumers, focusing on factors such as conspicuous consumption, perceived consumer effectiveness, green trust, perceived greenwashing, social media behavior and perceived scientific consensus. A quantitative approach was adopted, with data collected through Google Forms distributed via social media and through face-to-face interactions on the campus of Atilim University between March 2024 and September 2024. Purposive sampling was employed in this study and the collected data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) to test the proposed model. The findings revealed that conspicuous consumption, perceived greenwashing and the total social effect significantly influence sustainable clothing purchase behavior. Among the predictors, conspicuous consumption demonstrated the highest effect size, emphasizing the significant role of social status and self-expression in driving eco-conscious choices. Interestingly, perceived greenwashing showed a positive relationship with sustainable purchasing, suggesting that consumers may support brands perceived as greenwashing, potentially due to a lack of sustainable alternatives. Conversely, green trust, perceived consumer effectiveness and perceived scientific consensus did not exhibit significant direct effects, indicating that their influence may be more nuanced or context-dependent. This study provides valuable insights into the complex motivations driving sustainable consumption behavior among Generation Z. The findings highlight the importance of understanding social and psychological factors to effectively engage this generation in sustainability efforts, and inform strategies within the fashion industry.

Arazi Terk ve İlhakı Bağlamında Devletlerin Halefiyetinin Tabiiyet Üzerindeki Etkileri
Get PDFSavaşlar veya anlaşmalar gibi farklı yollar ile bir devletin hakimiyet kurduğu toprak parçası üzerinde sahip olduğu egemenliğin çeşitli şekillerle değişmesi mümkündür. Uluslararası hukukta devletlerin halefiyeti olarak ifade edilen bu durumun farklı hukuksal sonuçları bulunmaktadır. Bu sonuçlardan bir tanesi de o toprak parçası ile farklı nedenlerle ilgisi bulunan kişilerin tabiiyetleri üzerindeki değişim olmaktadır. Bu değişimin kimler üzerinde etkisinin olacağı ve ardından bu değişimin nasıl gerçekleşeceği konusu önem taşımaktadır. Arazi terk ve ilhakı, bir devlete ait toprağın bütününün ya da bir parçasının üzerindeki egemenliğin bir başka devlete geçmesidir. Toprak parçası üzerindeki egemenliğin değişmesi sonucu yapılan anlaşmaların pek çoğunda o toprak parçasıyla ilgili kimselere bir seçme hakkı (right to option) tanındığı görülmektedir. Çalışma kapsamında, öncelikle devletlerin halefiyeti ve uluslararası hukuk perspektifinden tabiiyet konusu incelendikten sonra devletlerin halefiyetinin tabiiyet üzerindeki etkileri arazi terk ve ilhakı bağlamında incelenecektir.By different means, such as wars or treaties, it is possible that the sovereignty of a state over the piece of land it dominates can be changed in various ways. This situation, which is expressed as the state succession in international law, has different legal consequences. One of these consequences is a change in the nature of the people who have something to do with that piece of land for different reasons. It is important to whom this change will have an impact and then how this change will take place. Land abandonment and annexation is the transfer of sovereignty over the whole or part of a state-owned land to another state. In many of the agreements concluded as a result of the change of sovereignty over the piece of land, it is seen that a right of choice (right to option) is granted to those concerned with that piece of land. Within the scope of the study, the succession of the states and the effects of the succession of the states on the nature will be examined in the context of land abandonment and annexation

No full text6545 sayılı Kanunla 2577 sayılı İdari Yargılama Usulü Kanunu'nun 45 inci maddesinde yer alan itiraz kanun yolu kaldırılmış ve aynı maddede yapılan düzenlemeyle, ilk derece mahkemelerince verilen ve kesin olmayan nihai kararlara karşı başvurulabilen olağan bir kanun yolu olarak istinaf kanun yolu idari yargılama usulüne dâhil edilmiştir. 20/07/2016 tarihinde yürürlüğe giren istinaf kanun yoluyla birlikte bölge idare mahkemeleri istinaf mercii olarak görev yapmaya başlamış ve iki dereceli yargılamadan üç dereceli yargılamaya geçilerek idari yargılamada önemli bir dönüşüm yaşanmıştır. İstinaf kanun yolu, uyuşmazlığa ilişkin maddi ve hukuki denetimin yapıldığı genel bir kanun yolu olarak düzenlenmiştir. Bu yolla hem adil ve etkin bir yargılamanın yapılması hem de uyuşmazlıkların birçoğunun istinafta kesinleşmesi öngörülerek yargılamanın daha hızlı sonuçlandırılması amaçlanmaktadır. Bunun yanında Danıştay'a giden dosya sayısının azalmasıyla birlikte Danıştay'ın içtihat mahkemesi olma rolünün kuvvetlendirilmesi de istinaf kurumunun amaçları arasında yer almaktadır. Çalışmada öncelikle, istinaf kurumunun hukuki niteliği ve tarihsel gelişimi incelenmekte, ardından kanun yolları içindeki yeri değerlendirilerek temyiz kanun yolu ve yürürlükten kalkan itiraz kanun yoluyla karşılaştırmalı analizi yapılmaktadır. Akabinde idari yargı bağlamında istinaf başvurusunun yapılma ve incelenme usulleri ile bölge idare mahkemelerinin istinaf başvurusu üzerine verdikleri karar türleri ve bu kararların hukuki sonuçları ele alınmaktadır. Neticeten çalışmada, istinaf kanun yolunun teorik çerçevesi ortaya konulmakta, uygulamadaki işleyişi analiz edilmekte ve karşılaşılan sorunlara çözüm önerileri sunulmaktadır.

With the entry into force of the appeal procedure on 20 July 2016, regional administrative courts began functioning as appellate bodies, marking a significant transformation in administrative judicial proceedings by transitioning from a two-tiered to a three-tiered system. The appeal procedure has been designed as a general legal remedy allowing both factual and legal review of disputes. It aims to ensure a fair and effective adjudication process and to expedite the resolution of cases by enabling a substantial number of disputes to be finalized at the appellate stage. Furthermore, the reduction in the number of cases submitted to the Council of State strengthens its role as a precedent-setting high court, which is also among the objectives of the appellate system. This study first examines the legal nature and historical development of the appeal procedure. Then, its place among other legal remedies is assessed, with a comparative analysis between the appeal, the former objection procedure, and the cassation procedure. Subsequently, the procedures for filing and examining an appeal within the context of administrative jurisdiction, the types of decisions rendered by the regional administrative courts upon appeal, and the legal consequences of such decisions are discussed. Ultimately, the study presents the theoretical framework of the appeal procedure, analyzes its practical functioning, and proposes solutions to encountered problems.

AdS3 Black Holes with Primary Proca Hair from a Regularized Gauss-Bonnet Coupling
Get PDFWe construct a consistent three-dimensional Einstein-Gauss-Bonnet theory as a vector-tensor theory within the generalized Proca class by employing a regularization procedure based on the Weyl geometry, which was introduced recently by Charmousis, Fernandes, and Hassaine [Phys. Rev. D 111, 124008 (2025).]. We then obtain an asymptotically Anti-de Sitter (AdS3), static, and circularly symmetric black hole solution with primary Proca hair. Afterward, we investigate the effect of the scalar-tensor GaussBonnet coupling constructed previously by different regularization schemes. We further generalize these solutions by incorporating an electric charge. As special cases, we find a regular black hole solution in addition to charged and uncharged stealth Banados-Teitelboim-Zanelli black hole solutions.Scientific and Technological Research Council of Turkey (TUBIdot;TAK) [124F058]G.

Impact of Green Wall and Roof Applications on Energy Consumption and Thermal Comfort for Climate Resilient Buildings
No full textOzbey, Mehmet Furkan/0000-0002-5813-3514Nowadays, reducing energy consumption and obtaining thermal comfort are significant for making educational buildings more climate resilient, more sustainable, and more comfortable. To achieve these goals, a sustainable passive method is that of applying green walls and roofs that provide extra thermal insulation, evaporative cooling, a shadowing effect, and the blockage of wind on buildings. Therefore, the objective of this study is to evaluate the impact of green wall and roof applications on energy consumption and thermal comfort in an educational building. For this purpose, a university building in the Csb climate zone is selected and monitored during one year, as a case study. Then, the case building is modelled in a well-calibrated dynamic building energy simulation tool and twenty-one different plant species, which are mostly used for green walls and roofs, are applied to the envelope of the building in order to determine a reduction in energy consumption and an increase in thermal comfort. The Hedera canariensis gomera (an ivy species) plant is used for green walls due to its aesthetic appeal, versatility, and functional benefits while twenty-one different plants including Ophiopogon japonicus (Mando-Grass), Phyllanthus bourgeoisii (Waterfall Plant), and Phoenix roebelenii (Phoenix Palm) are simulated for the green roof applications. The results show that deploying Hedera canariensis gomera to the walls and Phyllanthus bourgeoisii to the roof could simultaneously reduce the energy consumption by 9.31% and increase thermal comfort by 23.55% in the case building. The authors acknowledge that this study is solely based on simulations due to the high cost of all scenarios, and there are inherent differences between simulated and real-world conditions. Therefore, the future work will be analysing scenarios in real life. Considering the limited studies on the effect of different plant species on energy performance and comfort, this study also contributes to sustainable building design strategies.Atilim University-Undergraduate Research Projects [ATU-LAP-2021-11]This study is funded by Atilim University-Undergraduate Research Projects with a grant number of ATU-LAP-2021-11.Emerging Sources Citation Inde
The Relationship Between Soong Classification and Fracture Characteristics with Implant Removal for Distal Radius Fractures: A Comparative Study of 795 Cases
No full textYogun, Yener/0000-0002-3070-5509; Gezer, Mehmet Can/0000-0001-7034-2522;Introduction: Although there is no consensus in the literature, it is believed that the Soong classification system and fracture pattern are risk factors for plate removal in distal radius fractures. Hypothesis: The aim of this large-scale study was to evaluate the relationship between Soong classification, fracture pattern, and implant removal in distal radius fractures. Materials and methods: We retrospectively evaluated 795 patients who underwent surgery using a volar locking plate for distal radius fractures at our clinic between 2005 and 2022. The patients were divided into two groups: implant removed, and implant retained. The groups were examined for demographic data, follow-up periods, fracture classifications, and radiological parameters. Additionally, the patients were divided into groups and compared according to the Soong classification, which was determined according to implant placement. Indications for implant removal were also included in this study, and their relationships with other parameters were evaluated. Results: A total of 123 and 672 patients were included in the implant removed and retained groups, respectively. The average age of the implant removed group was significantly lower (p = 0.005). There were no significant differences between the two groups in terms of fracture classification or other radiological parameters. In the implant removed group, the rate of grade 2, according to the Soong classification, was statistically higher than that in the other groups (p = 0.019). Flexor tenosynovitis was the most common reason for implant removal. Conclusion: The Soong classification system is an important risk factor associated with implant removal. This risk may increase, particularly among young patients. Surgeons should consider placing the distal radius locking plate as proximally as possible to reduce the frequency of implant removal. Level of evidence: III; retrospective comparative stud
Key Drivers and Barriers Influencing the Adoption of 3D Printing Technology in the Turkish Construction Industry
No full textBu çalışmada, Türk inşaat sektöründe 3B baskı teknolojisinin benimsenmesini etkileyen temel faktörler incelenmiştir. Bu doğrultuda, kapsamlı bir literatür taraması sonucunda 27 teşvik edici ve 19 engelleyici faktör belirlenmiş olup, bu faktörlerin değerlendirmesi 106 uzmandan oluşan bir anket çalışması ile yapılmıştır. Bu faktörlerin önemi, Göreceli Önem İndeksi (GÖİ) kullanılarak değerlendirilmiş ve ardından Analitik Hiyerarşi Prosesi (AHP) ile faktörlerin önem düzeyleri belirlenmiştir. 3B baskı teknolojisinin daha hızlı inşaat, iş kazalarının azalması, enerji verimliliğinin artması ve karmaşık tasarımların daha kolay uygulanması gibi avantajlar sunduğu görülse de, bu teknolojinin benimsenmesini engelleyen başlıca zorluklar arasında 3B Beton Baskı için yeterli düzenlemelerin ve yapı kodlarının eksikliği, büyük ölçekli uygulamalar konusunda sınırlı bilgi ve yalıtım malzemelerinin yetersizliği yer almaktadır. Araştırma sonuçları, malzeme israfını azaltma ve daha fazla özelleştirme imkânı sağlama gibi faktörlerin 3B baskının inşaat sektöründe benimsenmesinde en önemli etmen olduğunu, gözetim maliyetlerinin azaltılmasının ise en az önemli teşvik edici faktör olduğunu ortaya koymuştur. Diğer yandan, siber güvenlik riskleri, potansiyel iş kayıpları ve basılı yapıların katmanlı ve pürüzlü yüzeyleri, en kritik engeller olarak belirlenmiştir. Bu araştırma, 3B baskı teknolojisinin inşaat sektörüne entegrasyonunun artırılması için bu etmenlerin ve engellerin hedefe yönelik stratejilerle ele alınması gerektiğini vurgulamaktadır.This study explores the key factors influencing the adoption of 3D printing technology in the construction industry, with a focus on Türkiye. An extensive literature review was conducted to identify 27 drivers and 19 barriers, which were subsequently evaluated through a survey of 106 industry experts. The significance of these factors was assessed using the Relative Importance Index (RII), and further analyzed with the Analytic Hierarchy Process (AHP) to prioritize and determine their relative importance. It is discovered that although 3D printing offers benefits such as faster construction, reduced site accidents, improved energy efficiency, and ease in implementing complex designs, its adoption is hindered by challenges including the lack of regulations and building codes for 3D Concrete Printing (3DCP), limited knowledge of large-scale applications, and insufficient availability of insulating materials. The results highlight that reducing material waste and enabling greater customization are the most significant drivers for adopting 3D printing in construction, while the reduction in supervision costs was the least important. Conversely, cybersecurity risks, potential job losses, and the layered and rough surface of printed structures were identified as the most critical barriers. This research underscores the need to address these drivers and barriers through targeted strategies to enhance the integration of 3D printing technology in the construction industry
On Some Permutation Trinomials in Characteristic Three
No full textIn this paper, we determine the permutation properties of the polynomial x3 +xq+2 −x4q−1 over the finite field Fq2 in characteristic three. Moreover, we consider the trinomials of the form x4q−1 + x2q+1 ± x3. In particular, we first show that x3 + xq+2 − x4q−1 permutes Fq2 with q = 3m if and only if m is odd. This enables us to show that the sufficient condition in [34, Theorem 4] is also necessary. Next, we prove that x4q−1 + x2q+1 − x3 permutes Fq2 with q = 3m if and only if m ̸≡ 0 (mod 4). Consequently, we prove that the sufficient condition in [20, Theorem 3.2] is also necessary. Finally, we investigate the trinomial x4q−1 + x2q+1 + x3 and show that it is never a permutation polynomial of Fq2 in any characteristic. All the polynomials considered in this work are not quasi-multiplicative equivalent to any known class of permutation trinomials
Calcium Phosphate Honeycomb Scaffolds With Tailored Microporous Walls Using Phase Separation-Assisted Digital Light Processing
No full textThe present study reports on the manufacturing of biphasic calcium phosphate (BCP) honeycomb scaffolds with tailored microporous walls using phase separation-assisted digital light processing (PS-DLP). To create micropores in BCP walls, camphene was used as the pore-forming agent for preparing BCP suspensions, since it could be completely dissolved in photopolymerizable monomers composed of triethylene glycol dimethacrylate (TEGDMA) and polyethylene glycol diacrylate (PEGDA) and then undergo phase separation when placed at 5 degrees C. Therefore, solid camphene crystals could be formed in phase-separated BCP layers and then readily removed via sublimation after the photopolymerization of monomer networks embedding BCP particles by DLP. This approach allowed for tight control over the microporosity of BCP walls by adjusting the camphene content. As the camphene content increased from 40 to 60 vol%, the microporosity increased from similar to 38 to similar to 59 vol%. Consequently, the overall porosity of dual-scale porosity scaffolds increased from similar to 51 to similar to 67 vol%, while their compressive strength decreased from similar to 70.4 to similar to 13.7 MPa. The mass transport ability increased remarkably with an increase in microporosity.National Research Foundation of Korea (NRF) - Korea government (Ministry of Science and ICT) [R2322622, RS-2023-00256327]; BK21 FOUR (BrainKorea21 Fostering Outstanding Universities for Research) - Ministry of education; National Research Foundation of Korea (NRF)This research was supported by the National Research Foundation of Korea (NRF) grant, funded by the Korea government (Ministry of Science and ICT) (Project No. R2322622, Contract No. RS-2023-00256327, International collaboration for bioinspired gradient 3D printing of zirconia bone grafts), and BK21 FOUR (BrainKorea21 Fostering Outstanding Universities for Research) funded by the Ministry of education and National Research Foundation of Korea (NRF).Science Citation Index Expande
Optimal Bore Diameter for Power Dense Traction Motor
No full textThe sine-wave permanent magnet brushless machine (PMSM) and Induction machine (IM) are the favorite motor types for traction applications. Modern permanent magnets (PM) are produced only in a few countries, and PM motors have higher efficiency. However, IM offers a robust, mature, rare-earth-material-free, and cost-effective. This study investigates the possibility of increasing IM efficiency by choosing an optimal bore diameter to reduce copper loss. Optimal bore diameter ensures that the motor operates at flux density levels that maintain a high power factor and give the possibility of increasing stator and rotor slot area to reduce copper loss. The investigation here is based on an experimentally verified FE model of the motor. This study illustrates that the rotor copper loss can be reduced by 25% with the choice of optimal bore diameter at rated voltage and frequency. A further 1% copper loss reduction is possible by introducing a sleeve over the stator slots to reduce air gap harmonics and, thus, surface losses on the rotor side. © 2025 Elsevier B.V., All rights reserved
