Economic opportunities, personal and work-related factors can play an important role in employees' intention to leave. Moreover, it is suggested in the literature that dyadic relationships between employees and their managers (i.e. leaders) are one of the important factors affecting that turnover intention. Although there are studies focusing on the relationship between leader-member exchange and turnover intention in the current literature, there is a need to explain how this relationship between leader-member exchange and turnover intention emerges, together with the related theoretical mechanisms. Considering that trust is an important factor determining the quality of relationships between managers and employees, it is however quite surprising that among studies in the existing literature investigating the ways how the quality of leader-member interactions affects employees' turnover intentions, there is no study that examines trust in the leader as a mediating mechanism. In this context, the current study examines the mediating effect of trust in leader in order to draw a clear picture of the relationship between the quality of leader-member interaction and the employee's intention to leave. This study makes use of social exchange and leader-member exchange theories to draw a clearer picture of this relationship. In order to test the hypothesis of the research, the data collected from 217 participants working in various hotels operating in Mugla province and carrying out different tasks were analyzed. In the analysis of the data collected by the survey method, PROCESS macro for SPSS/SAS developed by Hayes and regression analyses were used, so that direct and indirect effects were calculated. The findings of the study confirm that trust in leader mediates the relationship between leader-member exchange quality and employee turnover intention. In addition to its theoretical contribution that can fill the gap in the relevant literature, it is thought that the findings of this study may also help to retain the qualified workforce in the hospitality sector in the practical context. 2023-01-01T00:00:00Z https://hdl.handle.net/20.500.12809/11018 Investigation of the mechanical properties of polyurethane foam-filled FDM-printed honeycomb core sandwich composites for aircraft Kafalı, Haşim; Tunca, Erdem Sandwich composites are widely used in aerospace materials thanks to their low weight and high strength properties. The purpose of this study is to observe the effects of polyurethane foam filling on honeycomb core structures produced by additive manufacturing in terms of mechanical strength and moisture absorption properties. Within the scope of the study, honeycomb structures were produced by a 3D printer using polylactic acid (PLA) filament. Then, the honeycomb core was filled with polyurethane foam, which is supplied in liquid form. After the core material was given its final form, it was combined with an epoxy and carbon fibre facesheet material using the vacuum infusion technique. After the sandwich composite production was completed, in-plane compression, three-point bending, shear, and moisture absorption tests were applied. The polyurethane foam filling greatly increased the mechanical strength, but slightly more moisture absorption occurred in this structure compared to a hollow honeycomb structure. 2023-01-01T00:00:00Z https://hdl.handle.net/20.500.12809/10948 Bir Kobi'nin Banka Seçim Sürecinde Aralık Tip 2 Bulanık AHP Yöntemi Uygulaması Aydoğmuş, Ufuk; Yumurtacı Aydoğmuş, Hacer; Karaman, Davut; Yıldız, Ali; Can, Melih The banking sector is vital for world economies. Although there are broader definitions, the banking sector can be expressed as a sub-sector of the larger financial services industry, which also includes sub-sectors focusing on insurance, venture capital and private equity. One of the most important functions of the said sector is to protect the assets of depositors and to provide loans to individuals and businesses. Individuals consider many criteria in order to receive this service and choose the most suitable bank for them and work with that bank. It is known that the biggest challenge in front of the growth of small and medium-sized enterprises (SMEs) is the lack of access to finance. It is important that bank financings can be the main potential source of external financing for the growth of SMEs and on which criteria the bank should be selected based on which this financing can be provided. In this direction, the criteria and sub-criteria that SMEs consider during the bank selection stage were determined in the study and the most suitable alternative bank was selected by using the Interval Type 2 Fuzzy AHP method.; Bankacılık sektörü, dünya ekonomileri için hayati önem taşımaktadır. Daha geniş tanımları bulunmakla birlikte bankacılık sektörü, sigorta, risk sermayesi ve özel sermayeye odaklanan alt sektörleri de içeren daha büyük finansal hizmetler endüstrisinin bir alt sektörü olarak ifade edilebilmektedir. Söz konusu sektörün en önemli işlevlerinden birisi de, mevduat sahiplerinin varlıklarını korumak, kişilere ve işletmelere kredi vermektir. Bireyler bu hizmeti alabilmek için bir çok kriteri göz önünde bulundurmakta ve kendilerine en uygun bankayı seçerek, o bankayla çalışmaktadır. Özellikle küçük ve orta boy işletme (KOBİ)'lerin büyümesinin önündeki en büyük zorluğun finansmana erişim eksikliği olduğu bilinmektedir. Banka finansmanlarının KOBİ'lerin büyümesi için ana potansiyel dış finansman kaynağı olabileceği ve bu finansmanın sağlanabileceği bankayı hangi kriterleri baz alarak seçmesi gerektiği önem arz etmektedir. Bu doğrultuda çalışmada KOBİ'lerin banka seçimi aşamasında göz önünde bulundurdukları kriterler ve alt kriterler belirlenmiş ve Aralık Tip 2 Bulanık AHP yöntemi kullaılarak en uygun alternatif bankanın seçimi gerçekleştirilmiştir. 2023-01-01T00:00:00Z https://hdl.handle.net/20.500.12809/10929 The effect of fractional order mathematical modelling for examination of academic achievement in schools with stochastic behaviors Uzun, Pelin Yaprakdal; Uzun, Kıvanç; Koca, İlknur Academic achievement is very important, as it enables students to be well-equipped for professional and social life and shapes their future. In the case of a possible academic failure, students generally face many cognitive, social, psychological, and behavioral problems. This problem experienced by the students has been addressed with the mathematical model in this study. This mathematical model will be handled with the help of the fractional operator, and the existence, uniqueness, and positivity of the solutions to the model equation system will be examined. In addition, local and global stability analyses of the equilibrium points of the model are planned. Numerical simulations are performed with different values of fractional orders and densities of randomness. This study is very important in terms of its original and multidisciplinary approach to a subject in the field of social sciences. 2023-01-01T00:00:00Z
