Abstract: Loss functions and Risk functions play very important role in Bayesian estimation. This paper aims at the Bayesian estimation for the loss and risk functions of the unknown parameter of the H(r, theta), (theta being the unknown parameter) distribution The estimation has been performed under Rukhin’s loss function. The importance of this distribution is that it contains some important distributions such as the Half Normal distribution, Rayleigh distribution and Maxwell’s distribution as particular cases. The inverse Gamma distribution has assumed as the prior distribution for the unknown parameter theta. This prior distribution is a Natural Conjugate prior distribution for the unknown parameter because the posterior probability density function of the unknown parameter is also inverse gamma distribution The Rukhin’s loss function involves another loss function denoted by w(theta, delta) he form of w(theta, delta) is important as it changes the estimate. In this paper, three forms of w(theta, delta) have been taken and corresponding estimates have been derived. The three, forms are, the Squared Error Loss Function (SELF) and two different forms of Weighted Squared Error Loss Function (WSELF) namely, the Minimum Expected Loss (MELO) Function and the Exponentially Weighted Minimum Expected Loss (EWMELO) Function have been considered. A criterion of performance of various form of w(theta, delta) has ben defined. It has been proved that among three forms of w(theta, delta), considered here, the form corresponding to EWMELO is most dominant.

Abstract: The characteristics of prospector are to constantly find new market opportunities, carry out technological innovation, and obtain growth opportunities by moving to high value-added fields. Defender often choose a relatively stable market area and take effective actions, such as setting competitive prices or providing high-quality products and services, to actively prevent subsequent competitors from entering this industry. Although different strategic types of enterprises have different business preference, they cannot do without the active cooperation of employees in the process of strategy implementation, because they are the closest to the production and customers. If the incentive mechanism conflicts with employees' interests, employees may respond by leaving. Based on the sample of China's A-share listed companies from 2007 to 2019, this paper uses the fixed effect model to examine the impact of strategy on employee incentive mechanism and turnover rate. The empirical results show that, compared with defender, the pay gap of prospector is higher, and the above phenomenon is more significant in enterprises with lower labor intensity. In addition, prospector will also push up the turnover rate of employees, in which the pay gap plays a mediating role. This conclusion not only enriches the research of strategic theory and compensation contract, but also has some enlightenment for the relevant government departments to develop vocational training to improve employees' skills.

Abstract: In Ethiopia, small scale farmers contribute about 80% of the total population of the country and their land holding and also small, that farmer cannot allow the land to stay follow. Some developing region in the country is not fully benefit from the opportunities that can be generated by farm investment project. The study investigates the quality of life of people in near to Woldia town. The main objective of this study was to assess the impact of farm-investment on farmers’ quality of life in near to Woldia town. The appropriate methodology to meet sample size in this study was obtained by using simple random sampling techniques which gives equal chance to every members of population to be selected as a sample. The data was analyzed by using both descriptive and inferential statistics. And the model used for this study was binary logistic regression used to analysis the inferential statistics. And also chi-square used for testing association between dependent and independent variables like gender, marital status, family income, and occupation. This study also identifies gender, occupation, family income; marital status and educational level have impact on quality of life. Finally, the study recommended that the advantage of investments for farmers such as employment opportunities, construction of different social services like school, health center, and economic development to bring a families good quality of life.
