Development of a Perception Scale of Private Lesson: A Validity and Reliability Study

The purpose of the research is to develop a valid and reliable perception scale that can measure the perception of math teachers (198) and science teachers (120) towards private lesson. In the validity studies, the exploratory factor analysis was made with the SPSS 25.0 package program after that the confirmatory factor analysis was made with Lisrel 8.71 software. To develop the scale; 1. Creation of Item Pool 2. Obtaining Expert Opinion, 3. Creation of Pre-Trial Form 4. Factor Analysis 5. Confirmatory factor analysis. According to factor analysis; Kaiser Meyer Olkin (KMO) rate; .780; Bartlett test result: 7466.539; Cronbach alpha reliability coefficient is: .901. According to confirmatory factor analysis: Root Mean Square Error of Approximation (RMSEA) 0.043 (.05); p-Value for Test of Close Fit .00 (.05, Goodness of Fit Index (GFI) .96, Adjusted Goodness of Fit Index (AGFI) .93; Normed Fit Index (NFI) .97; Relative Fit Index (RFI) .96; Incremental Fix Index (IFI): .99; Degrees of Freedom: 38; Root Mean Square Residual (RMR): .037 and NonNormed Fit Index (NNFI): .98. According to research findings, the perception scale is valid and reliable so it can be used to determine math teachers and science teachers’ positive and negative perceptions of private lesson

Have Financial Stability Concerns Changed the Priority of the Central Bank of the Republic of Turkey?

This paper aims at analysing whether the Central Bank of the Republic of Turkey (CBRT), designing a new monetary policy framework to achieve financial stability in the last quarter of 2010, tries to pursue financial stability by putting price stability on the back burner. To this end, a forward-looking reaction function that is extended with nominal exchange rate gap and nominal domestic credits gap is estimated for the CBRT. The paper first performs unit root and cointegration tests and finds that the variables become stationary at first differences and that there is a cointegration relationship among variables. Then, the paper conducts the Kalman filter to obtain time varying parameters. The findings show that the coefficients of all explanatory variables did not change too much after the new monetary policy framework of the CBRT in the last quarter of 2010. Therefore, this paper asserts that the CBRT continues to pursue price stability as its primary goal and tries to achieve financial stability by using macroprudential tools. Thus this paper concludes that financial stability concerns have not changed the priority of the CBRT

Effectiveness of platelet-rich fibrin on tendon healing: experimental study in a rat model

Platelet Rich Fibrin (PRF) is a new biological augmentation material which is remarkable with its rich cellular components and growth factors. The aim of this study was to evaluate the effect of PRF on tendon healing in a rat model. PRF and control groups included eight rats. PRF was obtained with centrifuging blood collected from the rats and applied on the tendon repair site in Achilles tendon injury model created in rats. Effectiveness of PRF was evaluated with histological and immuno-histochemical methods. PRF improves formation of regular collagen structures (P<0.01) and also increases vascularity (P<0.05) of the tendon repair site. Cartilage formation occurred both in PRF and control groups. Gap formation was observed only in the control group. PRF is an autogenous biomaterial which enhances and support tendon healing
