  • Application of deep neural network (DNN) for experimental liquid-liquid equilibrium data of water + butyric acid + 5-methyl-2-hexanone ternary systems 

    LLE data are important for simulation and design of extraction equipment. In this study, deep neural network (DNN) structure was proposed for modelling of the ternary liquid-liquid equilibrium (LLE). LLE data of (water + butyric acid + 5-methyl-2-hexanone) ternaries defined at three different temperatures of 298.2, 308.2, and 318.2 K and P = 101.3 kPa, were obtained experimentally and then correlated with nonrandom two-liquid (NRTL) and universal quasi-chemical (UNIQUAC) models. The performance ...

  • Balance sheet effects of foreign currency debt and real exchange rate on corporate investment: evidence from Turkey 

    Authors:Demirkılıç, Serkan
    Publisher and Date:(Elsevier B.V., 2021)
    I analyze the balance sheet channels of depreciation of the Turkish non-financial corporations for 2003–2015. Having constructed a novel, hand-collected firm-level dataset on the composition and term structure of foreign currency assets and liabilities, I show that foreign currency debt and mismatch has a significant negative balance sheet effect on capital investment following a depreciation. The results remain same even after controlling for foreign currency assets and exports. This implies that ...

  • 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 ...

  • Economic Policy Uncertainty And Bank Credit Growth: Evidence From European Banks 

    Using a sample of 2977 private and listed banks in the EU-5 countries (the United Kingdom, Germany, Spain, Italy, France) for the years 2009–2018, this paper explores the impact of Economic Policy Uncertainty (EPU) on credit growth. Using panel data fixed effects methodology and controlling for endogeneity using two-step difference GMM estimators, our findings indicate that uncertainty in economic policies hampers the credit growth of European banks. Our bank type-based analyses indicate that the ...

  • Ethnic identity and economic welfare 

    In this study, we use rich survey data to understand the determinants of labor market success across refugees of different ethnicities in Turkey. In particular, we examine individual personality traits and integration barriers by considering metrics of refugees’ proximity to Turkey based on their home countries’ levels of cultural distance. Using microdata, we derive a refined index called ethnosizer scale to grasp the distance of minor ethnic identities in Istanbul to the dominant identity. ...

  • Gromov product structures, quadrangle structures and split metric spaces 

    Let (X,d) be a finite metric space with elements Pi, i=1,…,n and with distances dij≔d(Pi,Pj) for i,j=1,…,n. The “Gromov product” Δijk, is defined as [Formula presented]. (X,d) is called Δ-generic, if, for each fixed i, the set of Gromov products Δijk has a unique smallest element, Δijiki. The Gromov product structure on a Δ-generic finite metric space (X,d) is the map that assigns the edge Ejiki to Pi. A finite metric space is called “quadrangle generic”, if for all 4-point subsets {Pi,Pj,Pk,Pl}, ...

  • How organizational and geographic complexity influence performance: Evidence from European banks 

    We empirically investigate how bank internationalization, organizational complexity, and geographical complexity stemming from foreign-affiliate type and geographic dispersion affect parent bank stability and profitability. We base our analysis on unique, hand-collected data for the worldwide locations of subsidiaries and branches of EU banks. Our results show that internationalization benefits bank stability by reducing default risk, and it is significantly associated with lower earnings volatility ...

  • True variable-depth milling 

    Authors:Ulutan, Durul
    Publisher and Date:(Elsevier B.V., 2020)
    When tool wears during machining, cost of the process increases. Rapid tool wear leads to even further contributions to process cost and hence must be taken well care of. Among the many forms of tool wear, notch wear is one that has a big effect on the tool change decision. When the tool contacts the workpiece, a high amount of impact is created where depth of cut is. With continuous machining operations such as turning, the impact may not be as important; however, with interrupted machining ...
