Estimation in bivariate nonnormal distributions with stochastic variance functions
(Elsevier Science Bv, 2008) Tiku, Moti L.; Islam, M. Qamarul; Sazak, Hakan S.
Data sets in numerous areas of application can be modelled by symmetric bivariate nonnormal distributions. Estimation of parameters in such situations is considered when the mean and variance of one variable is a linear and a positive function of the other variable. This is typically true of bivariate t distribution. The resulting estimators are found to be remarkably efficient. Hypothesis testing procedures are developed and shown to be robust and powerful. Real life examples are given. (C) 2007 Elsevier B.V. All rights reserved.

By adopting a political economy perspective, this study investigates how the local actors of Turkish cinema, which were on the defensive, were able to overcome significant challenges.

Note on common fixed point theorems in convex metric spaces
(Mdpi, 2021) Kumar, Anil; Tas, Aysegul; 29252
In the present paper, we pointed out that there is a gap in the proof of the main result of Rouzkard et al. (The Bulletin of the Belgian Mathematical Society 2012). Then after, utilizing the concept of (E.A.) property in convex metric space, we obtained an alternative and correct version of this result. Finally, it is clarified that in the theory of common fixed point, the notion of (E.A.) property in the set up of convex metric space develops some new dimensions in comparison to the hypothesis that a range set of one map is contained in the range set of another map.

Organizational and supervisory support in relation to employee turnover intentions
(Emerald Group Publishing Limited, 2012) Tuzun, Ipek Kalemci; Kalemci, R. Arzu; 40702; 42537
Purpose - The present paper aims to examine the relationship between perceived organizational support (POS), perceived supervisory support (PSS) and turnover intentions. The paper also aims to investigate whether employee's individual cultural values regarding collectivism and individualism moderate the relationship between POS and turnover intentions. Design/methodology/approach - Data were obtained utilizing survey from a sample of 304 full-time employed adults working in insurance companies in Turkey. Employees completed regular survey that contained measures of the constructs of interest of this study. Findings - Results revealed that employees who perceive high levels of PSS but report low levels of POS will also report high levels of turnover intentions compared to employees who perceive low PSS and low POS. Practical implications - For increasing POS to be successful, managers must strive to find out the way to increase their social support, and then tailor support accordingly. Managers may benefit from considering cultural values during the support process. Furthermore organizations may develop different support policies for employees. Originality/value - The study's findings add to the growing body of research concluding that supervisor-related perceptions and attitudes can shape organization-related perceptions and attitudes.

The degree of financial liberalization and aggregated stock-return volatility in emerging markets
(Elsevier Science Bv, 2010) Umutlu, Mehmet; Umutlu, Mehmet; Akdeniz, Levent; Altay-Salih, Aslihan; 38254; 178057; İşletme
In this study, we address whether the degree of financial liberalization affects the aggregated total volatility of stock returns by considering the time-varying nature of financial liberalization. We also explore channels through which the degree of financial liberalization impacts aggregated total volatility. We document a negative relation to the degree of financial liberalization after controlling for size, liquidity, country. and crisis effects, especially for small and medium-sized markets. Moreover, the degree of financial liberalization transmits its negative impact on aggregated total volatility through aggregated idiosyncratic and local volatilities. Overall, our results provide evidence in favor of the view that the broadening of the investor base due to the increasing degree of financial liberalization causes a reduction in the total volatility of stock returns.
