A tensile constitutive model was proposed with the damage factor calculated by AE energy rate. The tensile strength of marble was discrete obviously and was sensitive to the inside microdefects and grain composition. With increasing of loading, the tensile stress-strain curve obviously showed nonlinear with the tensile tangent modulus decreasing. In repeated loading cycle, the tensile elastic modulus was less than that in the previous loading cycle because of the generation of micro damage during the prior loading. It means the linear weakening occurring in the specimens. The AE activity was corresponding with occurrence of nonlinear deformation. In the initial loading stage which only elastic deformation happened on the specimens, there were few AE events occurred; while when the nonlinear deformation happened with increasing of loading, lots of AE events were generated. The quantity and energy of AE events were proportionally related to the variation of tensile tangent modulus. The Kaiser effect of AE activity could be clearly observed in tensile cycle loading. Based on the theory of damage mechanics, the damage factor was defined by AE energy rate and the tensile damage constitutive model was proposed which only needed two property constants. The theoretical stress-strain curve was well fitted with the curve plotted with tested datum and the two property constants were easily gotten by the laboratory testing.展开更多

The GEM listed companies in information technology industry as an example, from the four aspects of the profit quality of listed companies, asset quality, growth quality, solvency, calculation of 83 listed companies of the weighted rate of return on net assets, net operating rate of 12 financial indicators, and through the SPSS21.0 analysis results of factor analysis, comprehensive evaluation the formation of the information technology industry, the financial quality of the gem, to provide a scientific basis for the decision to GEM listed companies healthy development.展开更多

Training is an important part of the enterprise human resources management. For enterprises is a kind of novel important human capital investment, as well as other capital investments, both benefits. Also be risky, because of the risks and benefits is coexistence, indivisible. To deal with the mentioned challenge, we combine the novel and state-of-the-art training methodology to maximize the effectiveness of the training process. In the article, we cast our new opinion together with the prospect for the future.展开更多

At the present stage, the long-effect mechanism for investor education is not only a demand of China＇s securities market on its healthy development, but also an objective reality that China＇s investor education is necessary to confront with. For these reasons, it is necessary for China to deepen investor education, expand investor education platform, strengthen risk prevention, and take initiative to build up a multi-level investor education system, and ultimately establish and improve a long-effect mechanism for investor education, so as to ensure the stable, harmonious and order development of China＇s Securities market in futures.展开更多

Marketing is usually described as a set of tools used by businesses to promote the exchange of goods and services produced in order to fully meet the demand of the community of the territory in which they operate. Therefore, to apply marketing to the territory, one needs to identify a set of rules for programming, evaluation, and promotion, in order to attract producers and consumers to an area, in which there are both tangible and intangible factors. The ability to create a development process is not only related to the possession of these factors, but also and above all to the ability to make them cohesive so that the area as a whole has more value than its individual components. In this paper, the authors show that it is not so much the actions carried out by local political institutions, but those of IKEA~ itself have contributed to the improvement of the area around Bari, where it has chosen to open a store.展开更多
