Öğe A comprehensive analysis of inter-relationships among overall service quality, trust, satisfaction and learner’s loyalty within the supportive vocational education and training(İstanbul Ticaret Üniversitesi, 2016) Yıldırım, Figen; Çengel, Özgür; Demirli, Cihad; Biçer, Ali Altuğ; Sağlam, MehmetIt is seen that education institutes use many techniques to increase the quality of the services being provided. However, as competition in the education sector has been rising dramatically, it is hard to differentiate the services offered. In this perspective, it is becoming hard to attract and keep loyal learners in education institutes. So, lifelong learning and continuing professional development are the two tools that enhance the level of loyalty to the education institutes. In this study, an attempt has been made to understand the factors that define learner’s loyalty in the Vocational Education Institutes. In addition, the relation of trust to the Institute, satisfaction, and learner’s loyalty variables to the service quality will be researched. In this sense, 184 questionnaires have been conducted to students who have attended the Public Oversight Board Education Program offered by Istanbul Commerce University’s Lifelong Learning Center. Data has been analyzed by Structural Equation Modelling. According to the results of the study, education institutes who deal solely with the issue of trust, satisfaction, and learner’s loyalty can have the potential to keep their learners on hand on a life-long basis thereby earning their loyalty to the fullest extent.Öğe The influences of relationship marketing in the housing brokerage market(İstanbul Ticaret Üniversitesi, 2016) Yang, Tsung-Ju; Tu, Yi-Chen; Shen, Ching-SungMany companies and salesmen try to build and maintain long-term relationship with their customer.

Within this scope, 6 developing countries (Argentina, Brazil, China, Malaysia, Mexico and Turkey) were analyzed in this study. In order to achieve this purpose, annual data for the periods between 1961 and 2014 was tested by using Engle Granger co-integration analysis, Vector Error Correction Model and Toda Yamamoto causality analysis. According to the result of the analysis, it was determined that there is not any relationship among three variables in Brazil and Mexico. On the other hand, we defined that increase in export causes higher growth rate in Argentina. Moreover, it was concluded that there is a causal relationship from import to export in China and Turkey. Furthermore, it was determined that export causes higher import in Malaysia. Therefore, it can be concluded that the relationship between import, export and growth rate is not same for all developing countries…Öğe A comparison of optimal portfolio performances of three optimization methods(İstanbul Ticaret Üniversitesi, 2016) Cevizci, AylinThis study compares performances of three portfolios established based on Markowitz optimization, shrinkage optimization, and Black- Litterman optimization. BIST30 companies are used to test the results. Markowitz optimization is unrestricted, thus generates the highest possible utility. However, portfolio weights display high values of short- selling needs. Shrinkage optimization restricts short selling needs gradually, but it does not block short- selling. On the other hand, Black- Litterman model totally prohibits short- selling. Results show that the lowest utility is originated by Black- Litterman model. Shrinkage model generates average returns and less- than- average risk. Therefore, shrinkage ratio is a strong candidate for future portfolio building. The results also suggest that short selling should be included in portfolio activities to maximize performance. Short- selling improves portfolio performance significantly.Öğe Managers’ personality traits over management styles and decision-making styles(İstanbul Ticaret Üniversitesi, 2016) Ülgen, Beliz; Sağlam, Mehmet; Tuğsal, TürkerThe paper seeks to offer a contribution to the extent literature on the role of managers’ personality characteristics over management styles and decision-making styles.

An empirical analysis of IPO’s competitive effect on Turkish firms(İstanbul Ticaret Üniversitesi, 2016) Ergincan, Yakup; Kiraz, Fatih; Uysal, ÖzgürThe motivation of this study is to approach the IPO issue from a different perspective. Most of the studies in the existing literature deal with three broad issues which are operating performance, stock performance, and the reasons to go public. However, there aren’t many studies which tackle the IPO issue from a pure competitive perspective which enables limited but clear results. This study contributes to the literature, not by answering a broad and old question but by providing new and partial evidence which seem to contradict the whole at first glance. Most of the 60 BIST (Borsa Istanbul) listed large industrial firms in this study have improved their relative ranks after their IPOs, when compared to their own large competitors most of which are not listed in BIST. These ranks are available in Turkey’s TOP 1.000 Industrial Enterprises annual lists and they are officially assigned by ICI (Istanbul Chamber of Industry) according to firms’ sales revenue figures. Thus, they provide us with the single and clear window to observe. Keeping in mind that this window is limited, this study comes up with some non-negligible findings and then elaborates on their significance for the IPO literature, raising more questions than answers for the sake of a more solid theory.Öğe The role of social media advertising in consumer buying behavior(İstanbul Ticaret Üniversitesi, 2016) Ertemel, Adnan Veysel; Ammoura, AhmadP Consumer buying behavior is known also as consumer decision making is the process by which individuals search for, select, purchase, use, and dispose of goods and services to satisfy require needs.

When this will repeatedly fail to meet expectations, a serious problem may become the main reason which contributes to the job decline. Therefore, a pattern of reduced performance indicates the need for a supervisory action from managers. Poor performance could be reflected under three main categories, such as employee availability, employee productivity, and employee conduct. The reasons and causes of this poor performance could be a personal issue related to the employee. Many types of personal problems are affecting the job performance in organizations, such as marital strife, financial difficulties and child care complication. More serious difficulties and the abuse of these problems-if not resolved-may cause unending issues at work. This problem is highly important especially that it can affect the job performance and the company income.

Amongst many others, Bollerslev, Chou and Kroner (1992) or (1994) are considered to be the précis of ARCH family models. In this direction the paper forecasts the stock market volatility of four actively trading indices from Muscat security market by using daily observations of indices over the period of January 2001 to November 2015 using GARCH(1,1), EGARCH(1,1) and TGARCH (1,1) models. The study reveals the positive relationship between risk and return. The analysis exhibits that the volatility shocks are quite persistent. Further the asymmetric GARCH models find a significance evidence of asymmetry in stock returns. The study discloses that the volatility is highly persistent and there is asymmetrical relationship between return shocks and volatility adjustments and the leverage effect is found across all flour indices. Hence the investors are advised to formulate investment strategies by analyzing recent and historical news and forecast the future market movement while selecting portfolio for efficient management of financial risks to reap benefit in the stock market.Öğe Cost of poor quality in energy sector(İstanbul Ticaret Üniversitesi, 2016) Aras, Özlem; Özcan, BurcuCompanies need to produce their product and services with lower cost in order to survive in the competitive global market. That is why; firstly they need to define the visible and invisible cost of poor quality factors and then need to eliminate these Poor Quality Costs by utilizing the various improvement methodologies. In order to define the poor quality, firstly the project team members need to be assigned between the cross functional departments. Then, the current status needs to be defined step by step by utilizing the various methodologies such as Pareto Analyze etc. As a second step, Root Cause Analyze is performed, and lastly the actions and action plan are defined. All these steps are systematized with some methodologies such as PDAC, Practical Problem Solving (PPS), Six sigma DMAIC & 8D. In this study, it is aimed to decrease the Warranty Cost which is a factor of the Cost of Poor Quality in a factory in the Energy Sector.

Using a unique dataset about information asymmetry, several proxies related to the information asymmetry are used to clarify certain aspects of market liquidity. In a sample of 131 companies with comprehensive data collected from company guides and Datastream, information asymmetry measured by analysts’ coverage is found to be an important determinant of market liquidity. In particular, market liquidity is lower where firms have larger analysts coverage and where firms are denoted with high degree of ownership concentration. The effect of analysts coverage is, however, found to be more marked in firms with high levels of ownership concentration. The study provides theoretical and empirical improvement of market liquidity literature towards an understanding of the information asymmetry proxies in ASE. Policymakers, after the 2007-2009 scandal have formed governance codes that highlight the importance of disclosure requirements as key responsibility of financial analysts. The link between analysts coverage and market liquidity established in this research provides evidence for insider investors on the roles and potential effectiveness of analysts in carrying this responsibility.Öğe Funds used by the European Union in the convergence approach and Turkey(İstanbul Ticaret Üniversitesi, 2016) Özkan, Ömer; Keleş, AhmetThe article is to show the twinning mechanism as a convergence tool in a states accession process.
