Does Guanxi matter to nonfarm employment?:
Because land is scarce, farmers in China increasingly have to rely on nonfarm activities to enhance their incomes. The functioning of rural nonfarm labor markets is therefore crucial in determining who has access to nonfarm employment. Previous studies have identified human capital as a key factor determining the selection of workers in the rural nonfarm economy. Using a detailed household survey of northern and northeastern China, this paper shows that guanxi (social networks), has also played an important role. With limited nonfarm job opportunities and poor market information, farmers with better social contacts are more likely to obtain nonfarm jobs. Moreover, guanxi has a larger effect on the nonfarm employment opportunities of male workers than female workers.Employment, Nonagricultural Rural areas China., Social networks China.,
A device-level characterization approach to quantify the impacts of different random variation sources in FinFET technology
A simple device-level characterization approach to quantitatively evaluate the impacts of different random variation sources in FinFETs is proposed. The impacts of random dopant fluctuation are negligible for FinFETs with lightly doped channel, leaving metal gate granularity and line-edge roughness as the two major random variation sources. The variations of Vth induced by these two major categories are theoretically decomposed based on the distinction in physical mechanisms and their influences on different electrical characteristics. The effectiveness of the proposed method is confirmed through both TCAD simulations and experimental results. This letter can provide helpful guidelines for variation-aware technology development
