The Study of Influencing Factors of Mobile E-commerce Software Use Intention-based on TAM and TRA

With the wide popularity of mobile devices, e-commerce software in the mobile client forms a larger consumer market, which makes the volume of e-commerce transactions having a wide range of growth. As the consumers have a frequent contact with mobile devices, which makes consumers pay more attention to security and entertainment of the e-commerce software. Past mobile e-business research typically focus on the related factors about transaction process, like interface design, services and user experience, but seldom study the factors about consumers. On the basis of the TAM, this paper not only added perceived security and perceived entertainment, but also the consumers’ personality factors like subjective norm in TRA, into the model. The study shows that PU, PEU, PS and PE all will have direct or indirect effects on use attitude and use intention, and subjective norms and use attitude will directly affect the consumers' use intention. Through the empirical analysis we found that e-commerce operators not only make the consumers experience more of usefulness and ease of use, security, and entertainment in the technology and services, but also improve the popularity with the aid of the mainstream media propaganda and star power to enhance the public's normative beliefs, which will ultimately affect the user behavior of the consumers.

Background: The objective was to study the effect of Scutellaria baicalensis Georgi ethanol extracts (SBGE) on immune and anti-oxidant function in U14 tumor-bearing mice. Materials and Methods: U14 tumor-bearing mice were randomly divided into eight groups: a control group, a cyclophosphamide (CTX) group, three dose groups of SBGEI (high, medium, low), and three dose groups of SBGEII (high, medium, low). After two weeks, the thymus and spleen weight indices of mice bearing U14 cervical cancer were calculated. Enzyme linked immunosorbent assays (ELISA) was used to determine the levels of serum IL-2, TNF-${\alpha}$, IL-8, and PCNA. MDA activity and SOD activity in plasma were measured with detection kits. Results: In the SBGE groups, thymus weight and spleen weight indices of U14 tumor-bearing mice were significantly higher than in the control group or CTX group (p<0.05). Compared to control group, the levels of serum IL-2 and TNF-${\alpha}$ in U14 tumor-bearing mice increased significantly, whereas the contents of serum IL-8 and PCNA decreased (p<0.05). The activity of SOD increased with the growing dose of SBGE, while the activity of MDA decreased significantly in the highe-rdose groups of SBGE. Conclusions: These findings suggested that SBGE, especially at high dose, 1000 mg/kg, showed significant immune and anti-oxidant effects infU14 tumor-bearing mice, which might be the mechanisms of SBGE inhibition of tumor growth.
