Abstract:
As enterprise systems (ES) becomes increasingly pervasive and commoditized in organizations, its service value emerges as a critical issue. Drawing on the customer value theory, this paper studies the relationship between user participation and service value of enterprise systems in the stage of enterprise system improvement. A survey of 220 employees in a large-scale industrial enterprise was taken to investigate the relationship between them. User participation has direct positive impacts on service value in the process of system improvement. Furthermore, information service quality and non-monetary sacrifice serve as mediating variables of the relationship between user participation in system improvement and service value even after controlling for individual variables such as users’ age, education, and IT-related education. This paper contributes to the theory on whether user participation matters in the process of enterprise system improvement. The findings can also encourage managerial practitioners to exploit user participation in organizations, in order to enhance service value of enterprise system.

Abstract:
During the diffusion of information on the network, the users generally have such an experience
that at the beginning they get aware of the news they never know and may be willing to inform
others, then their interests fade away, finally the information stops flowing. Meantime, their
points of view are changing as the networks’ structure changes. Therefore, this article brings in
the interest attenuation mechanism and the social networks consensus evolution mechanism on
the basic of the improved SEIR model. So to begin with, we establish a model to analyze how users’
interests change during the diffusion of information on the network. Second we establish another
model to analyze the evolution of the opinion during the diffusion of information on the network.
At last, we establish a final model by using dynamic equations adding the results of the two models
above.

Abstract:
We consider a one-dimensional nonlocal nonlinear equation of the form: $\partial_t u = (\Lambda^{-\alpha} u)\partial_x u - \nu \Lambda^{\beta}u$ where $\Lambda =(-\partial_{xx})^{\frac 12}$ is the fractional Laplacian and $\nu\ge 0$ is the viscosity coefficient. We consider primarily the regime $0<\alpha<1$ and $0\le \beta \le 2$ for which the model has nonlocal drift, fractional dissipation, and captures essential features of the 2D $\alpha$-patch models. In the critical and subcritical range $1-\alpha\le \beta \le 2$, we prove global wellposedness for arbitrarily large initial data in Sobolev spaces. In the full supercritical range $0 \le \beta<1-\alpha$, we prove formation of singularities in finite time for a class of smooth initial data. Our proof is based on a novel nonlocal weighted inequality which can be of independent interest.

Abstract:
We consider a transport-diffusion equation of the form $\partial_t \theta +v \cdot \nabla \theta + \nu \A \theta =0$, where $v$ is a given time-dependent vector field on $\mathbb R^d$. The operator $\A$ represents log-modulated fractional dissipation: $\A=\frac {|\nabla|^{\gamma}}{\log^{\beta}(\lambda+|\nabla|)}$ and the parameters $\nu\ge 0$, $\beta\ge 0$, $0\le \gamma \le 2$, $\lambda>1$. We introduce a novel nonlocal decomposition of the operator $\A$ in terms of a weighted integral of the usual fractional operators $|\nabla|^{s}$, $0\le s \le \gamma$ plus a smooth remainder term which corresponds to an $L^1$ kernel. For a general vector field $v$ (possibly non-divergence-free) we prove a generalized $L^\infty$ maximum principle of the form $ |\theta(t)|_\infty \le e^{Ct} |\theta_0|_{\infty}$ where the constant $C=C(\nu,\beta,\gamma)>0$. In the case $\text{div}(v)=0$ the same inequality holds for $|\theta(t)|_p$ with $1\le p \le \infty$. At the cost of an exponential factor, this extends a recent result of Hmidi (2011) to the full regime $d\ge 1$, $0\le \gamma \le 2$ and removes the incompressibility assumption in the $L^\infty$ case.

Abstract:
We construct global $\dot H^1\cap \dot H^{-1}$ solutions to a logarithmically modified 2D Euler vorticity equation. Our main tool is a new logarithm interpolation inequality which exploits the $L^{\infty-}$-conservation of the vorticity.

Abstract:
By using a new bilinear estimate, a pointwise estimate of the generalized Oseen kernel and an idea of fractional bootstrap, we show in this note that solutions to the Navier-Stokes equations with fractional dissipation are analytic in space variables.

Abstract:
Chitosan (deacetylated chitin) is derived from chitin, the component of the cell walls of fungi, the shells of insects, and especially crustaceans. Thus, it is can be serviced relatively inexpensively from widely available materials, which is the second most abundant polysaccharide in nature. Chitosan is the commonly used name for poly-[1-4]-β-D-glucosamine [3].As we know, the available antibody will be induced in 1 week after the antigens or vaccines enter animal's bodies. The pathogens can invade bodies easily in the empty period without specific immune defense. Some immunopotentiators can remedy such limitation. Chitosan is a good example. In this report, a method called "hardening in liquid phase" to prepare chitosan granules were established and some of characteristics such as the stability and the safety and the anti-FMDV activity of the chitosan granules were revealed.Chitosan was bought from Zhejiang yuhuan chemical company, China. The virus strains were O/CHN/99(LD50 7.0) and Asia 1/JS/05(LD50 6.0).Five gram of chintosan were dissolved in 200 ml of 2%(v:v) acetic acid with 10 ml tween-80, stirred continuously for 2 hrs, added 2 ml of 25% (v:v)glutaraldehyde, stirred rapidly for 5 min. and poured this Mixture into 500 ml liquid paraffin, stirred with High-speed magnetic stirrer for 1 hr to prepare chitosan granules. Then poured them into sand core funnel for vacuum pumping, washing them with petroleum ether, Isopropanol, Methanol, deionized water in turn, and stored at 2% glycine solution.The chitosan granules were put into six different solutions pH 3, pH4, pH 5, pH 6, pH 7, and pH 8 to observe their change of form, 10 ml in each same streptomycin bottle at room temperature. One week later, the chitosan granules in pH 3, pH4, and pH 5 were swelling and suspending and the height (13 mm) were almost same; the chitosan granules in pH 6 were swelling and suspending slightly but the height (3 mm) were lower; the chitosan granules in pH 7 and pH8 were deposited i

Abstract:
Objective: To investigate the effects of different methods of treatment, including tonifying the kidney, activating blood and soothing the liver on mice with autoimmune premature ovarian failure (POF). Methods: After preparing ovarian antigen with the ovarian tissue of female BALB/C mice, POF in female BALB/C mice was induced by immunization injection of the ovarian antigen on multiple subcutaneous sites and two posterior soles. The mice were treated with Liuwei Dihuang Pill, Shaofu Zhuyu Granule, Chaihu Shugan Pill respectively after the third immunization. Levels of folliclestimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), prolactin (PRL), testosterone (T), anti-ovarian antibodies (AOAb) and anti-zona pellucida antibody (aZP) in sera were analyze by enzyme-linked immunosorbent assay.Results: Compared with the normal group, the levels of serum FSH and LH were increased and the level of E2was decreased in the untreated group. AOAb and aZP positive rates in the untreated group were obviously higher than those in the normal group. Liuwei Dihuang Pill could significantly reduce the levels of FSH and LH and increase the level of E2as compared with the untreated group, but there were no significant differences in the AOAb and aZP positive rates. Shaofu Zhuyu Granule and Chaihu Shugan Pill could significantly reduce the positive rates of AOAb and aZP as compared with the untreated group, but no significant effect on the levels of FSH, LH and E2were observed. The drugs had no effects on contents of PRL and T in sera.Conclusion: Tonifying the kidney method can recover the ovarian function in POF mice mainly by regulating the hormone levels. Activating blood and soothing the liver methods can improve the humoral immune function in POF mice.

Abstract:
Objective: To investigate the preventive effect of Bushen Huoxue Recipe (BSHXR), a compound traditional Chinese herbal medicine, on autoimmune premature ovarian failure (POF) in mice.Methods: Ovarian antigen was prepared with the ovarian tissue of female BALB/c mice. A mouse model of POF was established by immunization injection of the ovarian antigen of isotype female mice on multiple subcutaneous sites and two posterior soles. The POF mice were treated with BSHXR after the first and third immunization. The levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) in peripheral blood were detected by enzyme linked immunosorbent assay.Results: Lymphocyte infiltration was appeared in ovarian stroma of POF mice. The levels of FSH and LH were evaluated and the E2 level was decreased significantly (P<0.05). BSHXR could reduce the increased levels of FSH and LH, increase the level of E2 and the number of growing and mature follicles. The efficacy of early treatment was better than that of late treatment.Conclusion: BSHXR can recover ovarian function in POF mice mainly by regulating the indiscriminate hormone level, and BSHXR has preventive effect on autoimmune POF in mice.
