Kadir Has University Academic Archive aims to gather all of scientific and academic works that are produced by the university staff under a single roof. We also have target of establishing a corporate memory. The materials that are in the Kadir Has University Academic Archive are put on open access suitable with the copyright rules. By doing that we may contribute to acceleration of international impact of our university on academic research and increase in the usage of publication.

  • Loan loss provisioning of US banks: Economic policy uncertainty and discretionary behavior 

    This paper examines the effect of economic policy uncertainty (EPU) on loan loss provisions (LLP). Using a sample of 6384 US banks and yearly data from 2009 to 2019 and addressing endogeneity (GMM and IV estimations), the findings reveal that in times of higher economic policy uncertainty, banks tend to increase their loan loss provisioning. Considering the four components of EPU, the findings document that the majority of the explanatory power on loan loss provisions originates from news-based ...

  • Cognitive styles and religion 

    Authors:Yılmaz, Onurcan
    Publisher and Date:(Elsevier B.V., 2021)
    I discuss recent research suggesting that individual differences in cognitive style give rise to and explain religious and related supernatural and paranormal beliefs. To do so, I illustrate intuitive cognitive biases (e.g., anthropomorphism) underlying these beliefs and then review the accumulated evidence indicating that non-believers are more open-minded, reflective, and less susceptible to holding epistemically suspect beliefs (e.g., conspiracy theories) on average than those who believe in ...

  • Physical-Layer Security With Optical Generalized Space Shift Keying 

    Spatial modulation (SM) is a promising technique that reduces inter-channel interference while providing high power efficiency and detection simplicity. In order to ensure the secrecy of SM, precoding and friendly jamming are widely adopted in the literature. However, neither of those methods can take advantage of SM. In this paper, a novel spatial constellation design (SCD) technique is proposed to enhance the physical layer security (PLS) of optical generalized space shift keying (GSSK), which ...

  • Does mood affect institutional herding? 

    Drawing on a unique data set of daily portfolio holdings for Turkish mutual funds we investigate the relationship between mood and institutional herding on the premises of various established mood proxies (weekend effect; holiday effect; Ramadan; sunshine). Results indicate that fund managers in Turkey herd significantly, with their herding growing in magnitude as the number of active funds per stock rises and appearing stronger on the buy-than the sell-side. Although the relationship of mood with ...

  • Large Eddy Simulation of Wind Flow over A Realistic Urban Area 

    Authors:Kirkil, Gökhan; Lin, Ching-Long
    Publisher and Date:(MDPI, 2020)
    A high-resolution large eddy simulation (LES) of wind flow over the Oklahoma City downtown area was performed to explain the effect of the building height on wind flow over the city. Wind flow over cities is vital for pedestrian and traffic comfort as well as urban heat effects. The average southerly wind speed of eight meters per second was used in the inflow section. It was found that heights and distribution of the buildings have the greatest impact on the wind flow patterns. The complexity of ...
