By creating a competitiveness framework and a system of heterogeneous indicators, this paper investigates the competitiveness of China and the US in terms of current status, historic change and global environment. Our research led to the following findings： core factors determine the level of competitiveness for China and the US; the national competitiveness of both countries is evolving towards structural homogeneity; and China and the US lead most countries in many common areas. China has the potential to overtake the US in competitiveness in the future. We suggest that China increase its competitiveness by promoting its advantages, addressing its weaknesses and focusing on core areas.展开更多

A set of formulations about inverse kinematics, Jacobin matrix, and forward kinematics for the high precision 6-HTRT parallel robots is presented. The analysis of errors existing in the manipulator is discussed and a novel approach for error correction is advanced. By DSP technique, inverse kinematics is solved in real time conditions with high precision and the hardware control system is given. The experimental results demonstrate the effectiveness of the proposed technique.展开更多

These investments are crucial for the long-term existence and development of a company, but their value is not disclosed on the assets side of the classical balance sheet. The most important argument of the mentioned approach＇s promoters is that the economic benefits stemming from such investments are uncertain. However, investments in human capital are those with the highest long-term benefits for the company. Therefore, human capital is the only element of the business process that can add value. Other elements （equipment, materials, and services） just transfer their value to products and services. In this paper, the elements of investments in human capital and the methods used to evaluate these investments are addressed. In addition, uniquely shaped financial performance ratios related to investments in human capital are presented along with the system of integrated ratios.展开更多

It is hoped that the study can help Vietnamese learners who study EFL （English as a foreign language） develop a positive attitude towards EL on one hand, and may motivate them to listen for pleasure on the other hand. This study may shed light on how to introduce EL into English foreign language classroom practice and how to maximize the students＇ exposure to suitable listening materials, which has been effectively adapted and reproduced, for the real classroom practice展开更多
