This study investigate perceived airline service quality and consumption emotion which classified into pre-consumption emotion and post-consumption emotion, on customer satisfaction and repurchase intention. Using survey date from 363 customers, the result reveals pre- consumption emotion positively relate to post-consumption emotion and perceived airline service quality, but no effect on customer satisfaction. we also find post-consumption emotion positively relate to customer satisfaction, but no effect on repurchase intention. In addition, we find perceived airline service quality positively relate to post-consumption emotion and customer satisfaction, but not significantly relate to repurchase intention and customer satisfaction positively effect on repurchase intention. These results suggest that airline managers must pay attention to not only cognitive factors but also experiential aspects of airline service.

Background: RhoGTPase-activating proteins (RhoGAPs) regulate RhoGTPases in cells, but whether individual reactive oxygen species (ROS) regulate RhoGAPs is unknown. Our previous published papers have shown that deleted in liver cancer 1 (DLC1) inhibits cancer cell migration by its RhoGAP activity. The present study was designed to explore the role of $H_2O_2$ in regulation of DLC1. Materials and Methods: We treated cells with $H_2O_2$ for 24h and phenotypic changes were analyzed by MTT, RT-PCR, Western blotting, immunofluorescence staining and wound healing assays. Results: $H_2O_2$ downregulated cyclin D1 and cyclin E to inhibit proliferation, and upregulated BAX to induce apoptosis in MCF-7 cells. Compared with non-tumorigenic cells, $H_2O_2$ increased expression of DLC1 and reduced activity of RhoA in cancer cells. Stress fiber production and migration were also suppressed by $H_2O_2$ in MDA-MB-231 cells. Conclusions: Our study suggests that $H_2O_2$ inhibits proliferation through modulation of cell cycle and apoptosis-related genes, and inhibits migration by decreasing stress fibers via DLC1/RhoA signaling.
Behaviour of micropiles in collapsible loess under tension or compression load

This study examines the behaviour of single micropiles subjected to axial tension or compression load in collapsible loess under in-situ moisture content and saturated condition. Five tension loading tests and five compression loading tests on single micropiles were carried out at a typical loess site of the Loess Plateau in Northwest China. A series of laboratory tests, including grain size distribution, specific gravity, moisture content, Atterberg limits, density, granular components, shear strength, and collapse index, were carried out during the micropile loading tests to determine the values of soil parameters. The loess at the test site poses a severe collapse risk upon wetting. The tension or compression load-displacement curves of the micropiles in loess, under in-situ moisture content or saturated condition, can generally be simplified into three distinct regions: an initial linear, a curvilinear transition, and a final linear region, and the bearing capacity or failure load can be interpreted by the L1-L2 method as done in other studies. Micropiles in loess should be considered as frictional pile foundations though the tip resistances are about 10%-15% of the applied loads. Both the tension and compression capacities increase linearly with the ratio of the pile length to the shaft diameter, L/d. For micropiles in loess under in-situ moisture content, the interpreted failure loads or capacities under tension are 66%-87% of those under compression. However, the prewetting of the loess can lead to the reductions of 50% in the tensile bearing capacity and 70% in the compressive bearing capacity.

机会识别是创业管理领域的重要研究主题,也是发展乡村旅游创业的重要前提条件之一。虽然创业机会识别研究已经取得了较多的成果,但仍缺少以乡村旅游单一行业创业样本来进行的实证研究。本研究基于社会资本理论和经验学习的观点,依据对139个乡村民宿创业者所做的的调查数据,对社会资本、先前经验与创业机会识别的作用机理进行了实证分析。研究发现,民宿创业者网络资源和网络规模均对创业机会识别有显著正向影响。民宿创业者的行业经验和职能经验对创业机会识别有显著正向作用,但工作经验对创业机会识别没有直接影响。这些结果表明,民宿创业者所嵌入的网络资源和网络规模越大,能够识别的创业机会就越多,拥有较多先前创业行业经验和职能经验,就能显著提高创业机会的识别。 Opportunity identification is the core issue of entrepreneurship research, and it is also an important prerequisite for the development of rural tourism. Although entrepreneurial opportunity identification research has achieved more results, there is still a lack of empirical research on rural tourism single industry. Based on social capital and experience learning perspectives, using data from 139 “Minsu” in China, which is now officially called homestay inn in China, we empirically examine the effects of social capital and previous experience on entrepreneurial opportunity identification. The results indicate that scales of embedded network and resources of social network have positively effect on entrepreneurial opportunity identification. The results also show previous industry experience and functional experience have positively effect on entrepreneurial opportunity identification, while previous working experience has no direct effect on entrepreneurial opportunity identification. These results show that entrepreneurs have a denser and larger scale of social network, they will have higher alertness for the potential entrepreneurial opportunities. These results also indicate that the entrepreneurs have more previous industry and functional experience, they will recognize more entrepreneurial opportunities.
