This study inquires into employee's intent to leave in South Korean dental clinics. A systematic research was undertaken on theories of leadership types, job satisfaction, organizational commitment and empowerment, and then interaction between these variables was verified based on quantitative data by using Structural Equation Model (SEM). The findings suggest that making improvements of empowerment, job satisfaction, and organizational commitment demand individualized consideration and charisma, the components of transformational leadership. As a way to reduce turnover intention, the role of job satisfaction and organizational commitment was more influential than that of empowerment. Also, a combination of charisma of transformational leadership and contingent reward of transactional leadership turned out to be the ideal leadership type to reduce turnover intention. Lastly, the harmony of individual goal with that of organization, apparent documentation of reward system, and stress control were recommended as practical solutions to improve organizational profitability and effectiveness and to reduce turnover rate in dental clinics.

This paper investigates the impact of working capital management on the firm's profitability. The research sample includes 119 non-financial listed companies on Vietnam stock market over a period of 9 years from 2010 to 2018. Two statistical approaches include Ordinary least squares (OLS) and fixed effects model (FEM) are employed to address econometric issues and to improve the accuracy of the regression coefficients. The empirical results show the negative and significant impacts of the working capital management, which measured by cash conversion cycle (CCC) and three components of the CCC including accounts receivable turnover in days (ARD), inventory turnover in days (INVD), and accounts payable turnover in days (APD) on the firm's profitability measured by return on assets (ROA) and Tobin's Q. It implies that firms can increase profitability by keeping the optimization of the working capital management measured by the CCC, which includes shortening the time to collect money from clients, accelerating inventory flow and hold the low payment time to creditors. Besides, the profitability of firms was impacted by the sale growth rate, firm size, leverage, and age. Therefore, this paper provides a new insight to managers on how to improve the firm's profitability with working capital management.

The study investigates the impact of accrual anomaly on stock return ratio of listed firms in Vietnam. Data were collected from listed firms for the period from 2008 to 2018. To learn about the causes of accrual anomaly in returns and future rate of returns on the Vietnamese stock market, this research is based on accrual analysis of Richardson, Sloan, Soliman, and Tuna (2006) on growth and effective components. We employ GLS regression model for examining the impact of accrual anomaly on stock return ratio and T-test for checking the difference between the lowest and the highest portfolio. The results show that accounting distortion is the main factor impacting the stock return, not growth determinant. Both two determinants of accounting distortion and growth contribute the explanation of the impact of accrual anomaly on profit and future stock return ratio. Experimental evidence confirms an abnormal existence of accrual in the Vietnam stock market. Aggregate accrual is negatively correlated with future operating profit and future stock return. However, after considering the factors contributing to the impact of future profitability and return on stock returns, the study results show that accounting distortion can account for low sustainability of income that is not growth.

We reported compositional separation(CS) into Co-enriched and Cri-enriched components inside the grains of Co-Cr based thin films prepared by rf sputtering. CS strongly depends on the sputtering conditions of substrate temperature and target composition. Tuning the microstructure of the Co-Cr films is important in order to employ the CS for high-density magnetic recording. We investigated the origin of CS from thermodynamic viewpoint. We employ a spinodal decomposition-like model to describe the origin of the CS in Co-Cr films. We consider the total free energy of the Co-Cr films as the sum of several free energies of; 1) thermodynamic mixing entropy of a binary solid solution, 2) magnetic ordering interaction(MOI) energy below the Curie temperature, and 3) excess interaction energy(XS) caused by the sputtering process as a function of temperature and composition. Those energies distorted the total free energy like the spinodal decomposition and caused the compositionally separated fine microstructure inside the grains. If the second derivative of the total free energy with respect to Cr composition becomes negative at a given substrate temperature, we may observe a metastable compositional separation inside the Co-Cr alloy films. We expect to exploit the microstructure of CS for ultra-high density magnetic recording.

Purpose - This research investigates the effect of disclosure quality with two main components, reliability and timeliness, on economic value added in Iran. Research design, data, and methodology - The sampling includes 170 Tehran Stock Exchange listed companies from 2008-12. Multiple regression analysis was applied to test the hypotheses and estimates of the coefficients. Firm size and return on assets were the control variables. Results - The results show that timeliness of information has a positive impact on economic value added. We did not find any significant relationship between disclosure quality and reliability of information and economic value added. The regressed model shows that there is no significant association between firm size and economic value added. The results also show that there is a positive association between return on assets and economic value added. Conclusions - Theoretically, timely information is effective in decision-making. This study shows that timeliness of information has positive effect on the creation of economic value added. However, disclosure quality, reliability, and firm size do not effect on economic value added. Companies with greater return on assets produce greater economic value added.

When it comes to the training program conducted by company to improve job performance ability, it would be not a investment but a waste if the training contents is not practically applied to the business accomplishment. Even though some people raise a question on the job application of postal distance training, funded by employment insurance, the study on the job application of postal distance training shows that the components of the training program have a positive effect on it and the model has 60.5% validity. Moreover, its control effect on environmental support and individual characteristics has been partially established. The study has been conducted by questioning survey with the employees who completed a postal education 3 months ago. With the result, we can find that the postal distance training benefits employees to improve their job performance abilities and expect that it continuously plays a crucial role in the field of company training through the development of high-quality training programs.

The study examines how foreign capital inflows affect stock market development in Pakistan for the period from July 2008 to June 2018. Several components of foreign capital inflows were used for empirical analysis, namely, foreign direct investment, foreign portfolio investment, and remittances. Further, market capitalization was used as a proxy for stock market development. The study uses an ARDL model for examining the long-run and short-run relationships between variables. We also analyze the bi-directional causality between the variables through the Granger causality test. Further, the presence of structural breaks was analyzed through the CUSUM and CUSUM Square test. The results suggest that in the long run, remittances have a positive and significant relationship with stock market development. However, foreign direct investment, foreign portfolio investment, and USD-PKR exchange rate do not have a significant impact on stock market development. The results also suggest that in the short run there is a negative relationship between FDI, USD-PKR exchange rate and market capitalization. Contrarily, we found a positive relationship between FPI and market capitalization. The results of Granger causality test suggest that remittances and USD-PKR exchange rate have a causal relationship with stock market development. Finally, we found no evidence of structural breaks in the dataset.

This paper explores the effect of IFRS on the financial performance of Iraqi commercial banks. It also investigates the value significance of financial performance statements using the Ohlson model, which has been used for the stock value relevance test in a number of studies. Using a sample of 66 listed banks on the Iraq Stock Exchange over three years of IFRS pre-adoption (2011-2013) and three years of IFRS post-adoption (2016-2018), we find financial performance components EPS and BVS value relevant to the stock returns. The findings also indicate that the implementation of IFRS has a major positive effect on the value relevance of the BVS, while the adoption of IFRS does not have a significant impact on the value relevance of the EPS reported by Iraqi banks. Our results indicate that the market value of the bank rises dramatically with enhanced financial performance reporting. In addition, the implementation of IFRS has a major effect on the financial performance measures and the value relevance of financial reporting in the Iraqi banking sector. This paper adds to previous value relevance literature and IFRS by throwing light on the banking sector in a developing country that has recently moved from applying local accounting standards to IFRS.
