<jats:p xml:lang="tr">Bu çalışma, perakende sektöründe boykot edilen ürünler özelinde tüketici sinizminin fiyat farklılaştırması stratejileriyle bertaraf edilip edilemeyeceğini incelemektedir. Tüketici sinizmi, bireylerin işletmelere ve pazarlama uygulamalarına karşı geliştirdiği şüpheci ve güvensiz tutumları ifade eder ve genellikle manipülatif veya etik dışı davranış algısıyla tetiklenmektedir. Özellikle son dönemlerde yaşanan İsrail-Filistin çatışması gibi sosyo-politik krizler, Türkiye’de İsrail menşeli ürünlere yönelik tüketici boykotlarının artmasına ve satın alma davranışlarının değişmesine neden olmuştur. Bu betimsel araştırmada, A101, BİM, ŞOK gibi büyük perakende zincirlerinin tüketici boykotlarına verdikleri tepkiler ve fiyat temelli pazarlama taktiklerinin tüketici kararlarını ne ölçüde etkilediği incelenmiştir. Bulgular, etik, milli veya dini gerekçelerle gerçekleşen boykotların marka sadakati ve imajını ciddi şekilde etkilediğini; ancak stratejik olarak uygulanan fiyat farklılaştırmasının (örneğin, indirimler, “1 alana 1 bedava” kampanyaları) kısa vadede olumsuz tüketici algısını kısmen azaltabildiğini göstermektedir. Bununla birlikte, çalışmada uzun vadeli güvenin ve sadakatin sağlanabilmesi için şeffaf, değer odaklı bir iletişim ve etik kurumsal davranışın gerekliliği vurgulanmaktadır. Elde edilen bulgular, yalnızca ekonomik değil; kültürel ve ahlaki değişkenleri de dikkate alan, tüketici merkezli pazarlama yaklaşımlarının önemini ortaya koymaktadır.</jats:p>

Çalışma köy okulunda öğrenim gören 8. sınıf öğrencilerinin görsel okuma biçimlerini tespit etmeyi amaçlamaktadır. Bu çalışmanın yapılma sebebi, literatürde 8. sınıf köy okullarında öğrenim gören öğrencilere yönelik görsel okuma özelinde yapılmış bir çalışmaya rastlanılmaması ve merkezi yerleştirme sınavlarında görsel okumaya yönelik soruların artış göstermesidir. Çalışma durum çalışma modeli ile kurgulanmış, nitel bir araştırmadır. Çalışma grubunu kolay ulaşılabilirlik ve ölçüt örneklem yoluyla seçilen 8. sınıfta öğrenim gören 56 köy okulu öğrencisi oluşturmaktadır. Çalışmada veri toplama aracı olarak, görsellere ait yorumların istendiği açık uçlu çalışma kâğıtları kullanılmıştır. Cevaplar betimsel analize tabi tutularak Hasan Efe’nin “Karikatürü Düşündüren İnsan” kitabında belirttiği görsel metin olarak karikatürün anlam yapısı konusunda derin yapı ve yüzey yapı başlıklarına göre kategorize edilerek incelenmiştir. Cevaplarda öğrencilerin çoğunluğunun yüzeysel yapıyı tasvir ettiği sonucuna ulaşılmıştır. Bu kategorideki 12 öğrencinin cevabında düz okumada öne çıkan sembollerin yüzeysel yapıdan uzaklaşarak simgelere başka anlamlar yüklediği göze çarpmıştır. Sonuç olarak köy okullarında öğrenim gören çocukların çoğunun görsel okuma açısından yeterince gelişemediği görülmüştür. Öğretmen görüşlerine göre öğrenci velilerinin eğitime ilgisizliği, bu öğrencilerin öğrenim hayatları boyunca farklı uyarıcılarla karşılaşmaması ve teknolojik araçlara rahat erişimlerinin mümkün olmaması ile okuma alışkanlıklarının edinmiş olmamaları, bu duruma sebep teşkil eden durumlardır.

<jats:p>This thesis aims to examine the Democrat Party (1950–1960) and the Motherland Party (1983–1991) governments in Türkiye primarily within the framework of Antonio Gramsci’s theory of hegemony, while drawing on Louis Althusser’s theory of Ideological State Apparatuses (ISAs) as a complementary theoretical perspective. The primary objective of the study is to analyze how political authority constructs hegemony not only through economic and political mechanisms but also by generating social consent through ideological apparatuses such as education, religion, the media, and culture. Within this framework, the Democratic Party period is interpreted as a liberal hegemonic order shaped by traditional norms and values, the principle of national will, and democratization. In contrast, the Motherland Party period is evaluated as a neoliberal hegemonic order structured around individualization, the market economy, consumer culture, and media-oriented discourses. The comparative analysis demonstrates that during the Democratic Party era, consent was predominantly constructed through democratic participation, a shared national identity, and cultural values, whereas during the Motherland Party period it was reconstructed through market integration, individual performance, and consumer culture. This transformation reflects the transition from a liberal hegemonic order to a neoliberal hegemonic order in Turkey.</jats:p>

<jats:p>Rapid advances in information and technology, together with globalization, have necessitated continuous policy reforms in education systems. In Türkiye, the 2023 Education Vision and the 2024 Century of Türkiye Education Model (CTEM) represent key reform initiatives aiming to promote student-centered, competency- and values-based education, digital transformation, equal educational opportunities, and improved assessment and evaluation processes. This study aims to evaluate the reflections of these reforms on the educational and administrative processes of Regional Boarding Secondary Schools (RBSSs) based on the views of teachers and school administrators. A qualitative research approach with a phenomenological design was employed. The study group consisted of 21 participants, including 11 teachers and 10 school administrators working in RBSSs during the 2025–2026 academic year. Data were collected through a semistructured interview form and analyzed using descriptive analysis. The findings indicate that the reforms have positively influenced teaching and learning processes, school management, assessment practices, and student development. However, time management, inadequate physical infrastructure, lack of instructional materials, and the need for in-service training were identified as challenges to effective implementation. In addition, the boarding school environment was found to support students’ responsibility, self-regulation, social skills, and values development. The study concludes that strengthening teachers’ professional development and improving school facilities are essential for the effective implementation of these reforms.</jats:p>

Realistic nonlinear seismic analysis of corroded reinforced concrete buildings requires accurate estiınation of the bond-reinforcement slip relationships that will be used for modifıcation of moment-curvature relationships. In this study, it is aimed to develop an experimental model to estimate the adherence strength of corroded reinforced concrete columns in order to fıll the gap related to the adherence strength recoınmended in the literature based on concrete compressive strength. For this purpose, 25 reinforced concrete columns, which will be produced according to the experimental program, will be tested under cyclic lateral displacement loading at two different axial load ratios of 0.20 and 0.40, at most four different corrosion levels and for a maximum of three concrete strength levels. An accelerated corrosion method will be used to carry to the reinforcing bars embedded in the reinforced concrete columns to the targeted corrosion level within the scope of this research. The actual corrosion levels are expected to be obtained as a result of gravimetric works by breaking the concrete and removing all longitudinal and transverse reinforcement bars from reinforced concrete columns. As a result of the experimental work, it is planned to develop an experimental model to estimate the adherence strength of reinforced concrete columns that have been corroded as a function of corrosion levels.

Inadequate attention during design and construction of some of reinforced concrete (RC) buildings in Cyprus has raised questions about the performance level of these existing buildings under future earthquakes. This study aimed to assess the seismic structural response of a four story existing RC building. For this purpose, first, the weak structural elements (e.g.\ the not safety column-beam joints and weak columns) were detected using linear static procedure (LSP) analyses on the basis of Turkish earthquake code. Then, two different strengthening methods were examined. In the first method which is common in Cyprus, the existing building was strengthened based on LSP, using column jacketing to satisfy seismic code requirements to remove the weak elements. The second strengthening method was carried out using nonlinear static procedures (NSP) to achieve the basic safety objective (BSO) performance level described in FEMA 356. For existing and both strengthened structures, pushover curves were obtained and following FEMA 356, performance points were calculated and compared. The seismic responses of existing and strengthened buildings were also assessed using incremental dynamic analyses (IDA). Nonlinear dynamic time history analyses have been performed by using SDOF models of these buildings under action of different scales of 20 ground motion records. Then IDA curves for each earthquake have been constructed. Limit – states at each performance level have been defined and summarizing the multi – record IDA curves, 16%, 50% and 84% fractile curves were obtained. Since selected structure represents common existing buildings in Cyprus, probabilistic structural damage estimation fragility curves were also obtained in terms of peak ground acceleration (PGA) for each considered performance level.

Problem statement: Inadequate attention during design and construction of some of Reinforced Concrete (RC) buildings in North Cyprus has raised questions about the performance level of these existing buildings under future earthquakes. Approach: Column jacketing, adding steel braces and new shear walls to an existing building are common strengthening methods used by practical engineers in North Cyprus to increase the performance level of an existing building. Results: The aim of this study was to determine the most effective strengthening method among these three mentioned techniques. As a case study, a four stories RC existing building was selected and assessed using finite element method. To remodel of the existing building, the survey works done included three main steps, detecting the reinforcement bars for beams and columns, actual used concrete strength and soil type. The beams and columns reinforcement bars were determined using Ferro scan method and the soil was sampled in Girne city to determine the soil type. The actual concrete strength was determined using core test. Three common strengthening techniques mentioned above, were applied to the existing building. Then the efficiency of each strengthening method was investigated on the basis of removing of weak columns, not-safe beam-column joints in shear and performance levels based on the FEMA356 and Turkish earthquake code. Conclusion/Recommendations: Results showed that column jacketing is the most effective method to remove the weak columns and not-safe column-beam joints in shear. Nonlinear static pushover results showed that despite that adding shear walls caused an increase in the structural base shear and a reduction in the maximum roof displacement and the number of collapsed elements at FEMA356 performance point, but it caused a remarkable reduction in the building ductility ratio.

High temperatures negatively affect the mechanical properties of concrete. This study examines the effect of elevated temperature on the mechanical properties of concrete produced with raw perlite aggregate. In the research, high temperature tests (25°C, 200°C, 400°C, and 600°C) were conducted on four different concrete mixtures (C25, C40, P25, and P40) produced using two different aggregate types (raw perlite aggregate and conventional coarse aggregate). Experimental results showed that as the temperature increased to 600°C, the compressive strength of conventional concrete samples decreased by 34.91% for C25 and 41.79% for C40, while the raw perlite aggregate samples (P25 and P40) exhibited significantly lower strength reductions of only 9.91% and 12.80%, respectively. These findings clearly demonstrate that raw perlite aggregate significantly enhances thermal resistance compared to conventional aggregates. Additionally, although the flexural strength of P25 and P40 samples at 25°C was initially lower due to the more limited stress-strain relationship of perlite, their post-exposure performance showed similar flexural behavior under increasing temperature. Microstructural analyses further confirmed that raw perlite aggregates contribute to minimizing micro-crack propagation and are more resistant to thermal degradation. In conclusion, raw perlite aggregate provides a sustainable and economical alternative for fire-resistant structures.

Corrosion is a long-term process resulting in the deterioration of the reinforced concrete (RC) structures. Most of the structural problems observed under the impact of either earthquakes or service loads might occur due to corrosion. Therefore, prediction of the remaining service life of a corroding RC structure plays an important role to prevent serious premature damage. In this study, a corroded, 25-year-old high school building which has been demolished at an earlier time was analyzed as a function of corrosion rate. Bond-slip relationships were taken into account in nonlinear analyses as a function of corrosion rate for different time periods (i.e., non-corroded (t: 0), existing (t: 25) and 50 years after construction); and they were used to ensure the effect of time-dependent slip rotation on the global structural behaviour by modifying the target post-yield stiffness of each structural member. Nonlinear push-over analyses were performed by defining the time-dependent plastic hinge properties as a consequence of corrosion effects. In order to define the performance levels of three different time periods, nonlinear incremental dynamic analyses (IDA) were performed for 20 earthquake ground motion records as a function of corrosion rate. Results showed that bond-slip relationship between concrete and steel is very important in evaluating the non-linear behaviour of corroded RC structures.

In this study, effect of pH by Fenton-like with zero-valent iron (ZVI) process, advanced oxidation process in the leachate treatment, was investigated. The effect of pH value on colour and COD removal from leachate was determined at five initial pH values, 2.0, 2.5, 3.0, 3.5 and 4.0 (ZVI = 0.05 g/L, H2O2 = 150 mg/L). The highest colour and COD yield were obtained at pH 2.0. The colour removal was 87.9% (in 620 nm wavelength) and the COD removal was 74%. Experimental data from COD degradation with the Fenton-like process were analysed by using the zero-, first-, second-order and BMG kinetic models.

The field of computer vision, which is widely studied area, is basically the imitation of the human vision system with digital devices. Computer systems perform operations through digital images or video images and decide according to the result. In this context, object recognition must be performed at the first stage in order to extract meaningful information from the image. In this study, the application of object recognition was developed using the deep learning method, which is especially popular in recent years. It has also been compared with classical machine learning methods often used in recognition applications. The proposed method developed with Convolutional Neural Network (CNN) has been compared by using the Histogram of Oriented Gradient (HOG) features and classifying them with Support Vector Machines (SVM) and K-Nearest Neighbor (KNN) methods. Experimental results show that the proposed CNN method is more successful than HOG+SVM, and HOG+KNN methods.

This study aimed to determine the material properties and the thickness of the layers of an unbonded jointed plain concrete pavement design over a deteriorated flexible pavement that lost its service capability. Maximum principal stresses occurring under the concrete pavement should not exceed the modulus of rupture of the concrete. Three-dimensional finite element analyses using ANSYS (Release 18.1 SAS IP, Inc.) software were carried out with the Taguchi method. The most reliable solution for the pavement design was investigated with whole configuration axle loading that reflects the realistic traffic situation. The stress values under the concrete slab due to the positive temperature gradient neglected in the American Association of State Highway and Transportation Officials (AASHTO) method were also investigated. The concrete slabs are exposed to these stresses for longer than the axle loads. Temperature distributions throughout the thickness of the concrete slab were calculated with the bilinear formulas suggested in the study. Axle loadings were applied on both the pavement edge and corner to reflect the most critical loading condition in the pavement design. The critical axle type was found to be 1.2. It was observed that a 0.15 m concrete thickness was appropriate for the concrete class, joint spacing and hot mix asphalt (HMA) elasticity modulus levels used for the 1.22, 1.122, and 1.2 + 111 axle types, but it was not appropriate for the 1.2 axle types. The slab thicknesses calculated with the AASHTO method, and the finite element method were found to be close to each other. It was determined that the concrete thickness significantly affected the maximum principal stress, with a performance statistic (S/N) value of 1692 for the 1.2 axle type. This was followed by the modulus of elasticity of the concrete with an S/N value of 0.356, the modulus of elasticity of the existing flexible pavement with an S/N value of 0.244, and the concrete joint spacing with an S/N value of 0.105. A practical design guide was recommended to extend the service life of a highly deteriorated flexible pavement with the construction of unbonded jointed plain concrete.
