Because of the increase of consumption of fr-esh vegetables and fruits (Protective factors), decreaseof eating salted pork and fishes which was verified tohave strong mutagenecity (risk factors), acute inflamma-tion and erosions accompanying with chronic gastritis havegot striking improvement. At the same time, serum betac-arotene also raised gradually. The authors stressed thatimprovement of economic situation and dietary habits mayplay an important role in primary prevention of precurso-res of stomach cancer but decrease of incidence of thiscancer is an event of 30 years or more later as the letentperiod of stomach cancer is rather long.展开更多

The existing TM implementations made significant performance degradation on NUMA system because they ignored the slower remote memory access. To solve this problem, a latency-based conflict detection and a forecasting-based conflict prevention method were proposed. Using these techniques, the NUMA aware TM system was presented. By reducing the remote memory access and the abort rate of transaction, the experiment results show that the NUMA aware strategies present good practical TM performance on NUMA system.展开更多

The unsuccessful realization of BITA will lead to the waste of organizational resources, the reduction of return on investment and eventually the loss of competitive advantage. In recent years, coevolution has received widespread attention due to its ability to describe the dynamic relationship between IT and business. Multiple principles such as quickening learning action loops and adopt suitable organizing principles for achieving business and IT coevolution(BITC) are obtained. However, the continuous BITC is still hard to be achieved because of the lack of complete BITC management. This paper focuses on the management process of the BITC and how to perform it gradually. A coevolution framework combines the enterprise architecture(EA) approach with the coevolution analysis is proposed, which contains the design of EA, the sensing and governance of the misalignment and the procedure of the EA misalignment prevention.The steps for the governance and prevention of misalignment are discussed in particular. Through comparison with the principles,characteristics and methods of coevolution in the literature, the proposed framework is evaluated. The results show that the proposed framework is effective for BITC implementation.展开更多

Anti-corruption mechanism refers to a organic operation system of the interaction,interconnection and constraint between the constituent elements( parts) and elements of national anti-corruption,and as a system,anti-corruption mechanism should have the characteristics of system aticness,comprehensiveness,transparency,legalization,public participation,scientific dynam ic,and internationalism. The construction of deepening anti-corruption mechanism is the need for reconstructing the ruling legitimacy of the party and the governm ent. Adhering to the principle of treating both root causes and symptoms is necessary in the construction of anti-corruption m echanism,com bating and punishing corruption is an important part of anti-corruption,and the prevention and control of corruption is the basic project of anti-corruption. Therefore,the construction of prevention and control mechanism in the anti-corruption mechanism has a more far-reaching significance.展开更多

Traditional approaches to prevention fall short. A broader understanding of prevention and the cultural transformation associated with it mean that there are new demands on companies and their employees. People and organisations need competences for this transformation; they must be empowered to create humane living and working conditions. In order for people and organisations to be able to develop competences for the transformation,appropriate structural conditions in educational institutions and workplaces must be created. These conditions should enable people to experience a feeling of competence,to feel part of something and to perceive their actions as autonomous.展开更多

Compared with the USA,the structural relief system is far from perfection on the legislative level and the judicial level.With the implementing of Centralized Examination Methods for Operators and Temporary Provisions of Concentrated Assets and Business Stripping of Operators,the structural relief system in China has been preliminarily established. However,from the technical level,microcosmic element pillar system related to stripping system has not been established yet. According to the experience in law enforcement in the USA,China shall also formulate Handbook on Implementing Relief System in the Antitrust Scrutiny of Operators to provide helpful guide for the structural relief system in China.展开更多
