In this paper, taking Shanghai Red Express Co. for example, on the basis of famous Western scholars Price-Mueller （2000） model, anaiyzing the impact ofemployee turnover variable, such as salary and welfare is lower than expected, work pressure, lack of promotion opportunities, the company management confusion, etc, and then proposed targeted measures to reduce the rate of turnover and retain talent for the company, such as establishing scientific and reasonable salary system, improve the working environment, to establish a reasonable training system and career development path.展开更多

In this paper, we propose an approach named First and Others （F＆O） counting. By introducing a tuning parameter a and a weight β, two new properties are obtained： （1） flexible assignment of credits by modifying the formula （with the change of a） and applying preference to the individual author by adjusting the weights （with the change ofβ）, and （2） calculation of the credits by separating the formula for the first author from others. With formula separation, the credit of the second author shows an inflection point according to the change ofa. The developed theorems and proofs concerning the modification of a and fl reveal new properties and complement the base theory for informetrics. The F＆O schema is also adapted when considering the policy of＇first-corresponding-author-emphasis＇. Through a comparative analysis using a set of empirical data from the fields of chemistry, medicine, psychology, and the Harvard survey data, the performance of the F＆O approach is compared with those of other methods to demonstrate its benefits by the criteria of lack of fit and coefficient of determination.展开更多
