The research develops a model of relationship satisfaction positioned within the conceptual framework of Wackman, Salmon & Salmon (1986/87). This conceptual framework has been extended with additional variables to account for the complexities of the agency-client relationship in the Turkish advertising industry today. A survey of Turkey's largest advertisers was conducted, using the face-to-face interview method. Factor analysis and regression analysis (of factor-scores) were then used to test the proposed framework. All of the dimensions of the model were found to significantly influence the advertiser's satisfaction with the agency. The results suggest that advertisers principally value the agency's creativity and the relationship with the agency. Compatibility, agency's costconsciousness, service breadth, leadership capability, and perceived contribution to advertiser's sales, market share, and brand targets were also found to be important for satisfaction. Other significant predictors are people-related attributes, strategic input, trust, cooperativeness, and prestige and full-service capability. The empirical findings are consistent with the theory and confirm the importance of relationship attributes in advertiser's satisfaction. None of the control variables was found to be significantly associated with satisfaction. The findings contribute to research concerning relationship marketing and have managerial implications.Yayın Competitiveness of professional business services: Case of Turkish advertising agencies(Işık Üniversitesi, 2008) Şahin, Çiğdem; Ansal, Hacer; Işık Üniversitesi, Sosyal Bilimler Enstitüsü, Çağdaş İşletme Yönetimi Doktora ProgramıThis study seeks to examine the extent to which internal factors affect the competitiveness of professional service firms.

Since computers have strated to play an important role in our everyday life, researchers have focused om improving the interaction between these two entities. The usability of computer & software systems has been the main area of interest . Various techniques have been developed to measure usability. Some researchers have focused on objective usability whereas some have focused on the psychological aspect by examining subjective usability. When the objective is to examine a potential set of users' perceived usability, the context dependent nature of this specific literature even added to the difficulties. This research supplies an in-depth view of usability and computer attitude literatures, and offers computer attitude as an important variable which impacts perceived usability. A field study has been conducted in a population of 26 universities' Students in Istanbul to test the model. The research finding indicate that computer attitude is an important variable that does have a significant effect on perceived usability.Yayın The board of directors as one of the mechanisms of corporate governance and its impact on the performance of Turkish family companies: A survey(Işık Üniversitesi, 2009) Perek, Sevgi; Uyargil, Cavide; Işık Üniversitesi, Sosyal Bilimler Enstitüsü, Çağdaş İşletme Yönetimi Doktora ProgramıBoard of directors, one of the four structural elements of corporate governance, has attracted a great deal of attention in the past fifteen years due to corporate failures, concerns about the performance of corporations and the way they are governed. Inefficient government of companies was shown as one of the main reasons of the ongoing international and domestic financial crisis, bankruptcies and company frauds. As an emerging market, Turkey's ability to attract international capital is relatively low. Analysis of the extant literature on Turkish companies indicate that a majority were founded and governed by families where only a small percent can survive into the third generation. This brings the necessity to examine the management and control systems and the board of directors in detail to achieve sustainable development in family companies. The main purpose of this study is to empirically analyze the relationship between the company performance of Turkish listed companies in Istanbul Stock Exchange and the compliance levels of the board processes to the corporate governance principles issued by Capital Markets Board of Turkey.Yayın Determining sovereign credit default swap spread by extended merton model in selected emerging markets(Işık Üniversitesi, 2008) Türk, Mehmet; Karaaslan, Mehmet Emin; Işık Üniversitesi, Sosyal Bilimler Enstitüsü, Çağdaş İşletme Yönetimi Doktora ProgramıThis thesis examines if the Merton's structural model for corporates can be extended to emerging market sovereigns such as Brazil,Mexico,Turkey and Russia in a comparative perspective.For utilizing extended Merton model,the parameters chosen for the determination of the credit default swap spreads are the central bank foreign currency reserves and gross external debt besides the benchmark external debt's volatility incorporated into these calculations.In return,the credit default swap spread rates are estimated and compared for the named four developing markets.Emprical evidence shows that there is a significant correlation between the market rates and the model findings. A comparison of the results for these countries underlines the fact that building foreign currency reserves and diminishing for foreign currency liabilities or switching external debt to local currency debt might lower the credit risk spreads significantly. Furthermore,determining credit default swap market rates requires extensive volatility analysis.Yayın Circuit models with mixed lumped and distributed elements for passive one-port devices(Işık Üniversitesi, 2006-01-23) Şengül, Metin; Aksen, Ahmet; Yarman, Bekir Sıddık Binboğa; Işık Üniversitesi, Fen Bilimleri Enstitüsü, Elektronik Mühendisliği Doktora ProgramıIn this thesis, to model measured data obtained from an actual passive one-port device, a circuit modeling method with mixed lumped and distributed elements is proposed. Namely, measured data is modelled by means of its Darlington equivalent, in other words, as a lossless two-port terminated with a resistance. Two network topologies are examined. The first topology is ladder networks connected with unit elements and the second one is cascaded separate lumped and distributed networks. In the proposed modeling method, analytic expression of the input reflection coefficient of the two-port model is obtained by using gradient method, and then, after synthesizing this two-variable function, the model is reached. Thus, for the first time in the literature, a two-variable circuit modeling method is presented.Yayın Factors affecting research and development (R&D) collaboration of multinational enterprises (MNEs) and their local partner firms : a case study of Turkish automotive industry(Işık Üniversitesi, 2009) Tuncay Çelikel, Aslı; Ansal, Hacer; Işık Üniversitesi, Sosyal Bilimler Enstitüsü, Çağdaş İşletme Yönetimi Doktora ProgramıThis thesis focuses on disclosing the factors that affect the Research and Development (R&D) collaboration between Multinational Enterprises (MNEs), and their Turkish partner firms, in the automotive industry. Following the literature review and pre-test interviews with the experts from the industry a number of different factors were identified. The methodology of the research was 2Case Study3 in order to provide an in-depth exploration of the factors. There are three case studies namely: Tofaş-Fiat, Ford Otosan-Ford and Hyundai Assan-Hyundai. The primary data was collected from 40 respondents (R&D/production managers and employees) by in-depth face-to-face interviewing. Findings yield that the most important factors affecting R&D collaboration for the local companies were production, innovation & R&D capabilities and then absorptive capacity of the local companies. The most important factor affecting MNE's R&D location decisions was the main R&D policy of the MNE (criteria for possible R&D collaboration, openness to R&D collaboration and strategic goals). Another factor, competition between other R&D departments in different countries, and other R&D department's competency were found as moderate level of importance. R&D Managers of Fiat, Ford and Hyundai found the Turkish government's R&D incentives very attractive, and found that Turkey's infrastructure, socio-economic conditions and cheap but skilled labor force were appropriate for undertaking R&D collaborations. Social factors (mutual trust, level of commitment and cultural conflicts) were found to be an important influence in MNE's R&D location decisions. The findings are expected to contribute to the R&D efforts and innovativeness of the Turkish Automotive Industry.Yayın A service quality measurement framework for mobile betting : an assessment of theory and practice(Işık Üniversitesi, 2008) Tireli, Ali İlhan; Yılmaz, Ensar; Gönensay, Emre; Dereli, Toker; Işık Üniversitesi, Sosyal Bilimler Enstitüsü, Çağdaş İşletme Yönetimi Doktora ProgramıSince year 2000 Mobile Services or in other words Value Added Services are continuously growing. Business priority at the emergence of these services has been to launch as many services as possible, regardless of the profits or perfect functionality.

This study addresses the IPO mispricing phenomenon in Istanbul Stock Exchange (ISE) market, and aims to provide additional evidence on IPOs. Using 1996-2004 data, pricing of the IPOs were compared in terms of several determinants in both short and long term. These determinants were found to be explaining the short term performances, the first day mean abnormal return for the IPOs that are underwritten by well known banks or investment agencies was found to be %4 and this increased to %6 for the IPOs with badly reputed underwriters. In the next step, we show that the underpriced and overpriced IPOs both outperform the market in the short-run but the underpriced stocks stopped outperforming after the first year. Finally, the tests on the effects of the five factors on the short-run and long-run performance of the IPO stocks explain us that they are significant only in the short term.
