Book Part Case Study 8: Igaranti: Expanding the Frontiers of Mobile Banking Innovation(Springer International Publishing, 2016) Ozturkcan, Selcen; Tunçalp, DeniziGaranti have claimed many awards and recognitions in addition to the wide press coverage. Two years into its launch iGaranti counted for an active user base of 110 k. However the spread of its reach was only about 2?% of the active mobile banking users in the market. Mr. Yilmaz worried about the bottlenecks that had limited further user acceptance and engagement. © Springer International Publishing Switzerland 2017.Book Part Cash Holdings and Corporate Governance: Evidence From Turkey(IGI Global, 2019) Akben Selçuk, Elif; Selçuk, Elif Akben; Şener, Pınar; Şener Tournus, PınarThis chapter investigates the empirical factors affecting corporate cash holdings with special emphasis on corporate governance variables for a sample of Turkish-listed nonfinancial firms over the period 2006 to 2010. The findings reveal a significant non-linear relation between family ownership and cash holdings. In addition, while board structure does not significantly affect the level of cash holdings, tunneling increases cash reserves of firms. Furthermore, the results indicate that cash flow, leverage, other liquid assets that can be used as cash substitutes, the degree of tangibility of assets, and firm size are important in determining cash holdings among Turkish companies.Book Part Choice of Finance in an Emerging Market: the Impact of Independent Decisions Politics and Religion(Springer International Publishing, 2017) Davutyan, Nurhan; Davutyan, Nurhan; Öztürkkal, Belma; Öztürkkal, Ayşe BelmaThis paper is based on a KONDA 1 Research and Consultancy 2 survey conducted in May 2014 on 2607 people forming a representative sample of the Turkish population. It focuses on how people’s religious and political characteristics impact the independence of their decision making regarding saving and borrowing. An earlier study by Davutyan and Ozturkkal (2016) reports saving and borrowing decisions strongly correlate with income, education, marital status and region within country. Furthermore, 54% of those surveyed did not save and the main motivation for those who saved was to finance children’s education or home purchase. Religious people and those with a conservative lifestyle are less likely to borrow from family and friends. Older, married and working individuals are more likely to have difficulty paying back loans. According to the results of this survey, religious individuals are less likely to independently decide on their investment choices. Thus, religious people tend to make investment decisions together with family, elderly and respected relatives.Book Part Comparison of Post Outage Bus Voltage Magnitudes Estimated by Harmony Search and Differential Evolution Methods(2009) Ceylan, Oğuzhan; Ceylan, Oğuzhan; Özdemir, Aydoğan; Dağ, Hasan; Dağ, Hasan; Özdemir, SerpilContingency studies are indispensable tools of both the power system planning and operational studies. Real time implementation of operational problems makes necessary the use of high speed computational methods while requiring reasonable accuracies. On the other hand, accuracy of the results and the speed of calculation depend on branch outage modeling as well as solution algorithm used. This paper presents a comparison of post outage bus voltage magnitudes calculated by two meta-heuristic approaches; namely differential evolution (DE) and harmony search (HS) methods. The methods are tested on IEEE 14, IEEE 30, IEEE 57, and IEEE 118 bus test systems and the results are compared both in terms of accuracy and calculation speed.Book Part Determinants of Corporate Cash Holdings: Firm Level Evidence From Emerging Markets(Springer, 2017) Akben Selçuk, Elif; Selçuk, Elif Akben; Altiok-Yilmaz, AyseThe objective of this chapter is to investigate the factors affecting corporate cash holdings in five emerging markets namely Brazil Indonesia Mexico Russia and Turkey. The sample consists of 1991 firms listed on the major stock exchange of their countries and covers the period between 2009 and 2015. The model is estimated by Arellano–Bond dynamic generalized method of moments. Results show that firms which use higher leverage in their capital structure hold more cash. More profitable firms are shown to have higher levels of cash holdings. Another variable which has a positive effect on the level of cash holdings in any given period is the level of cash holdings in the previous period as shown by the positive and significant coefficient of the lagged dependent variable in the model. Liquidity and firm size have a negative and statistically significant impact on the level of corporate cash holdings. Firms with higher level of capital expenditures are also shown to hold less cash. Finally growth opportunities do not have a significant impact on the level of cash holdings for the firms in the emerging markets analyzed. © Springer International Publishing AG 2017.Book Part Female Social Entrepreneurship in Turkey(Palgrave Macmillan Ltd., 2015) Uygur, Duygu; Günay, Gonca; Kahraman, Elif Bezal; Günay, Gonca[Abstract Not Available]Book Part Global Trends in International Human Resource Management(Cambrıdge Univ Press, 2014) Rofcanin, Yasin; İmer, Havva Pınar; Zingoni, Matthew; İmer, Havva Pınar[Abstract Not Available]Book Part The Government-Sponsored Enterprises(John Wiley & Sons Ltd, 2011) Acharya, Viral V.; Öncü, T.

Taking into account the socioeconomic importance of hazelnut, the stakeholders of hazelnut domain still have problems such as availability, meaningful, accuracy of the hazelnut related data. Providing data to stakeholders is crucial for sustainable agricultural activities. This data should be freely available to everyone to use and republish. With the aforementioned reasons "Open Data" is an efficient way in Turkish Agriculture.In this paper, we shall investigate the open data term and semantics in the context of hazelnut data management. In addition, a data processing model with regard to agricultural open data is proposed.Book Part Regulation of Rating Agencies(John Wiley & Sons Ltd, 2011) Altman, Edward I.; Öncü, T.
