Generalized Clifford Algebras as Algebras in Suitable Symmetric Linear Gr-Categories

By viewing Clifford algebras as algebras in some suitable symmetric Gr-categories, Albuquerque and Majid were able to give a new derivation of some well known results about Clifford algebras and to generalize them. Along the same line, Bulacu observed that Clifford algebras are weak Hopf algebras in the aforementioned categories and obtained other interesting properties. The aim of this paper is to study generalized Clifford algebras in a similar manner and extend the results of Albuquerque, Majid and Bulacu to the generalized setting. In particular, by taking full advantage of the gauge transformations in symmetric linear Gr-categories, we derive the decomposition theorem and provide categorical weak Hopf structures for generalized Clifford algebras in a conceptual and simpler manner

Market Economy Model of Chinese Management -Case of Haier-

To explore a new style of Chinese management by the case study of Haier is the objective of this paper. Haier is the largest consumer electronics company in China. Wages of workers are only based on piece rate and determined by the rightly done jobs and the defects in their jobs. The evaluation of workers for wages is individualistic, instantaneous, quantitative, monetary, competitive and open. There is practically no room for discretional evaluation by supervisors and managers. Engineers who want to become the heads of new product development projects apply for the position with new product development plans (open competitive bidding). The salary of project managers and their subordinate engineers is determined by the market performance of new products such as the sales, the quality claims from customers and the costs of new products. Haier's management is based on the market principles of economics. It is the market economy model of management. And it is spreading among growing Chinese companies. We may say that they are more capitalistic than Japanese companies and even American companies.
