Item The Transnational Spread of Turkish Television Soap Operas(2014) Karlidag, Serpil; Bulut, Selda; J-2443-2015Turkish soap operas that are primarily popular in Turkic Republics, Middle East, and the Balkans have in recent years spread to different countries. With the entry into Ukrainian, Pakistani, Russian, and Chinese markets last year, tens of Turkish soap operas now reach their viewers in over 50 countries, and generate export revenues. Short-term return on investment, new communication technologies, Istanbul's ` magnetic nature attracting new talents' and different sociocultural forces and policies play key role in such extensive spread of Turkish TV series. As cultural commodities, TV series, while the images and identities they contain spread, reach at the same time new customers through geographical expansion, and increase the earnings of producers. Yet, the distribution of soap operas is important as much as their production. This requires focusing on the commodities with geo-linguistic and geo-cultural markets rather than companies producing these commodities. Therefore, demand for these non-Western commodities of different geographies points to a contra-flow. In a sense, while new media centers are emerging elsewhere other than the United States of America (USA)-Europe axis, it can be spoken of a regional opposition to the Western hegemony, though there is not an important historical leitmotive or transformation. Thus, in this study, relations between power, cultural commodity, and geography and the spread of Turkish soap operas in different geographies will be discussed with a political economic approach by also drawing attention to the historical commonality.Item A Novel Approach for Estimating Heat Transfer Coefficients of Ethylene Glycol-Water Mixtures(2014) Bulut, Murat; Ankishan, Haydar; Demircioglu, Erdem; Ari, Seckin; Sengul, Orhan; https://orcid.org/0000-0002-6240-2545; AAH-4421-2019Ethylene glycol-water mixtures (EGWM) are vital for cooling engines in automotive industry. Scarce information is available in the literature for estimating the heat transfer coefficients (HTC) of EGWM using knowledge-based estimation techniques such as adaptive neuro-fuzzy inference systems (ANFIS) and artificial neural networks (ANN) which offer nonlinear input-output mapping. In this paper, the supervised learning methods of ANFIS and ANN are exploited for estimating the experimentally determined HTC. This original research fulfills the preceding modeling efforts on thermal properties of EGWM and HTC applications in the literature. An experimental test setup is designed to compute HTC of mixture over a small circular aluminum heater surface, 9.5 mm in diameter, placed at the bottom 40-mm-wide wall of a rectangular channel 3 mm x 40 mm in cross section. Measurement data are utilized as the train and test data sets of the estimation process. Prediction results have shown that ANFIS provide more accurate and reliable approximations compared to ANN. ANFIS present correlation factor of 98.81 %, whereas ANN estimate 87.83 % accuracy for test samples.Item Is Empathy Important in Teaching Popular Culture?(2017) Raw, LaurenceItem The Representation of Trauma and Trauma Coping Strategies in Grace Nichols's I is a Long Memoried Woman(2017) Sarikaya Sen, Merve; 0000-0003-2091-2536; AEG-2545-2022Using the historical background of the Middle Passage and slavery and drawing on the tools provided by trauma studies, this study carries out a comprehensive analysis of Grace Nichols's I is a Long Memoried Woman (1983). The starting hypothesis explored in this study is that I is a Long Memoried Woman represents traumatic experiences of the Middle Passage and slavery as well as trauma coping strategies adopted by Afro-Caribbean slaves, especially black slave women. Accordingly, this study first delves into four main trauma representation strategies in I is a Long Memoried Woman: repression, haunting, repetition and traumatic pastoral. It then explores the representation of trauma coping strategies adopted by Afro-Caribbean peoples: return to religion and spirituality, dissociation, escape through imagination and revenge fantasies. In doing so, this study demonstrates that there is a possibility for trauma victims such as Afro-Caribbean peoples to heal their wounds and move on as represented in I is a Long Memoried Woman.Item An Alternative View of Ecotourism with a Specific Reference to Turkey(2016) Erdogan, Nazmiye; Erdogan, Irfan; 0000-0002-5588-0039; A-5267-2019Item The Effect of Thyroid Dysfunction on Nesfatin-1 And Adiponectin Levels in Rats(2017) Atici, Emine; Mogulkoc, Rasim; Baltaci, Abdulkerim Kasim; Menevse, Esma; 0000-0003-2461-1212; 0000-0002-5477-5667; 0000-0002-6547-4798; 28796641; AAL-5444-2020; ABA-7831-2020; AAG-5865-2019Background: Changes in thyroid hormone concentrations may affect adiponectin concentrations through various mechanisms. A molecule released primarily from the fat cells adiposities; adiponectin has important effects on the regulation of body weight. Aim: The present study aimed to explore the effects of experimental thyroid dysfunction and its treatment on nesfatin-1 and adiponectin levels in rats. Methods: The study included 40 adult male Sprague-Dawley rats which were grouped as follows: (1) control; (2) hypothyroidism [hypothyroidism was induced by intraperitoneal injection of 10 mg/kg/day propylthiouracil (PTU) for 3 weeks]; (3) hypothyroidism + thyroxine group [after hypothyroidism was induced by 2-week PTU injection, they were treated with high-dose L-thyroxine (1.5 mg/kg/day) for 1 week]; (4) hyperthyroidism [hyperthyroidism was induced by 3-weeks' thyroxine injection (0.3 mg/kg/day)]; (5) hyperthyroidism + PTU (after hyperthyroidism was induced by 2-weeks' thyroxine injection, the animals were given 10 mg/kg/day PTU for 1 week). Blood samples taken at the end of the study were analyzed to measure nesfatin-1 and adiponectin levels. Results: It was found that nesfatin-1 levels increased in hypothyroidism, while adiponectin levels decreased (p < 0.001). In experimental hyperthyroidism, on the other hand, both nesfatin-1 and adiponectin levels were found significantly elevated (p < 0.001). Conclusion: The results of the study indicate that nesfatin-1 and adiponectin levels were modified considerably in hypo- and hyperthyroidism, whereas with the restoration of the thyroid function, modified hormone levels went back to normal.Item What Can Adaptation Studies Learn from Fan Studies?(2017) Raw, LaurenceItem The Effects of Facebook and Whatsapp on Success in English Vocabulary Instruction(2018) Cetinkaya, Levent; Sutcu, Selim Soner; 0000-0002-0167-4846; C-7503-2019The purpose of this study is to determine the effects of Facebook and WhatsApp on success in English vocabulary instruction and the learners' opinions about the implementation process. In the study, mixed method model, which combines both quantitative and qualitative data, was used. The success of the students in Facebook, WhatsApp, and control group showed a significant difference between the pretest and posttest, meaning that the learning environments had different effects on the increase of success of students. The analysis revealed that the difference in the mean scores of the students in WhatsApp, Facebook, and control group was significant, and WhatsApp has been more effective in the increase of the success. Although more increase in the mean scores of Facebook group was observed compared with control group, this increase was not found significant. Furthermore, students expressed their willingness to go on the practice not only in their present course, but also in their other courses as well. They also opined positive opinions that learning could also take place unconsciously. However, a few students reacted negatively against the unnecessary messages and the timing of some messages. The results indicated that, compared with Facebook, WhatsApp is more effective in teaching vocabulary.Item Co-Culture of Rat Luteal Cells with Islet Cells Enhances Islet Viability and Revascularization(2018) Boyuk, Gulbahar; Yigit, A. Arzu; Aydogan, Ilkay; 0000-0001-5837-6877; 30187177; AAD-1857-2020; C-2636-2017Islet cell transplantation is a major treatment strategy for type I diabetes, and has proven to be effective for maintaining glucose homeostasis. However, this treatment requires an extended period of immunosuppression to prevent rejection and recurrent transplantation to maintain function. Thus, to enhance the properties of transplanted islet cells, we examined the effect of the co-culture of luteal cells, which secrete progesterone, on islet cell viability, functionality, and revascularization. It was found that islet viability and functionality were higher in the co-cultured group than in single cultures of islets at 48 and 96 h, in parallel with increased progesterone and vascular endothelial growth factor (VEGF) secretion from luteal cells. In the co-culture groups, VEGF levels at 48 and 96 h and CD31 levels at 48 h were significantly higher than those in the islet groups (p < 0.001 and p < 0.05, respectively), and basic fibroblast growth factor (bFGF) levels were increased at 96 h (p < 0.001). Thus, co-culture with luteal cells may increase islet vascularity by enhancing VEGF and bFGF levels for up to 96 h, which could help to markedly increase the pre-transplantation time to allow for effective immunosuppression therapy. This method may also promote islet cell viability and functionality. Progesterone and angiogenic factors secreted from luteal cells may be responsible for these positive effects.Item Classification of acoustic signals with new feature: Fibonacci space (FSp)(2019) Ankishan, Haydar; 0000-0002-6240-2545; AAH-4421-2019In this study, a new feature and feature space (FSp) are introduced by using the approach of Fibonacci series formation. The results are presented as two experimental studies. The nine groups of acoustic signals and pathological human voices are investigated in the first and second experiments, respectively. Convolutional Neural Network (CNN) and Multi-Class Support Vector Machines (M-SVMs) are used to figure out the effect of the proposed feature and its FSp on the classification accuracy. It is observed that the proposed feature and its formed space yield significant results for the discrimination of those signals. Experimental studies show that the classification accuracy of test data is increased by 5.3% when the proposed feature is used with CNN and M-SVMs. In addition, each acoustic group is significantly discriminated in both experimental studies. It is concluded that the proposed feature and its space can be used as a temporal feature for different purposes such as automatic speech recognition, pattern recognition, and emotional voice discrimination etc. (C) 2018 Elsevier Ltd.
