Caixia Liu,홍진환 한국무역연구원 2020 무역연구 Vol.16 No.3

Purpose This study examines how consumer cosmopolitanism and ethnocentrism is related to Chinese cross-border e-commerce(CBEC) consumers’ purchase intention and channel choice. Particularly, we focused on CBEC channel choice (foreign or local) and investigated its relationship with consumer cosmopolitanism and ethnocentrism. Design/Methodology/Approach The data were collected from Chinese CBEC consumers. To test our hypotheses, we developed a questionnaire based on previous literature and the questionnaire survey was conducted. Based on the empirical data from 231 Chinese CBEC consumers, we analyzed the data with structural equation model. Findings Our results found that consumer cosmopolitanism is more positively related with foreign CBEC than local CBEC regarding purchase intention, while consumer ethnocentrism is not significantly related with CBEC regarding purchase intention. Research Implications This study examines a new and emerging phenomenon of Chinese cross-border e-commerce, and the results implies that managers involved in cross-border e-commerce in the Chinese market can make better use of the cosmopolitanism and ethnocentrism variable in marketing.

后疫情时代企业社会责任对顾客重购意愿的影响研究

刘彩霞(Caixia Liu) YIXIN 출판사 2023 Journal of China Studies Vol.1 No.1

疫情持续近三年,对很多行业特别是旅游行业有很大的影响,本研究以携程民宿为研究对象,研究疫情期间企业通过提升社会责任来赢得顾客信任、提升品牌价值。当前关于企业社会责任在危机中能否产生好的结果尚未形成定论,本研究借助利益相关者理论、规范激活模型和计划行为理论,研究了消费者信任和公司的消费者身份调节社会责任对于网上重购意愿的影响,并研究了个人和社会规范对于企业社会责任影响重复购买意愿的路径。调研样本选择了 528 名中国的携程网用户,研究结果表明战略性慈善活动会直接影响消费者对于企业社会责任的评价,环境的、经济的和伦理的要素也会影响消费者对于企业社会责任的评价。感知企业社会责任不会直接影响消费者的重购意愿,但是会通过消费者对于企业的认可间接影响消费者的重购意愿,而个人规范会弱化感知社会责任和消费者信任对于重购意愿的影响。 The epidemic has been ongoing for nearly three years and has had a significant impact on many industries, especially the tourism industry. This study focuses on Ctrip homestays to study how companies gain customer trust and enhance brand value by enhancing social responsibility during the epidemic. At present, there is no consensus on whether corporate social responsibility can produce good results in crises. This study uses stakeholder theory, normative activation model, and planned behavior theory to study the impact of consumer trust and corporate consumer identity regulation of social responsibility on online repurchase intention. It also investigates the pathways through which individual and social norms affect corporate social responsibility’s willingness to repeat purchases. The survey sample selected 528 Chinese users of Ctrip. The research results showed that strategic charity activities directly affect consumers’ evaluation of corporate social responsibility, and environmental, economic, and ethical factors can also affect consumers’ evaluation of corporate social responsibility. Perceived corporate social responsibility does not directly affect consumers’ willingness to repurchase, but it indirectly affects consumers’ willingness to repurchase through their recognition of the company, while personal norms weaken the impact of perceived social responsibility and consumer trust on repurchase intention.

Scaling analysis of magnetic-thermal behaviors in ferromagnetic insulator LaCoO3 thin film

Liu Hao,Fan Jiyu,Zheng Huan,Rahman Azizur,Qian Fengjiao,Wang Caixia,Ma Chunlan,Zhu Yan,Yang Hao 한국물리학회 2021 Current Applied Physics Vol.28 No.-

The structure, surface topography and magnetic properties of LaCoO3 (LCO) thin films deposited epitaxially on the SrTiO3 substrates have been investigated in detail. The LCO thin films show a typical ferromagneticparamagnetic (FM-PM) phase transition at 78 K. Based on the measurements of isothermal magnetization around the Curie point, the magnetic entropy change (ΔSM) of LCO thin films under various applied magnetic fields were obtained. By utilizing scaling theory, all of the ΔSM curves can be re-scaled, confirming that the FMPM phase transition is second-order magnetic phase transition. Moreover, the magnetic entropy change -ΔSM features a maximum around TC, whereas, power law fitting of -ΔSmax M with H gives n = 0.9704, which is obviously deviating from the standard value n = 2/3 for the Landau mean field model. This indicates that the mean field theory cannot be used to explain the critical behavior of LCO thin films which implies that the critical behavior of LCO thin films may involve complex magnetic interactions. These interactions are correlated with a long-term puzzling finding in this system why its Curie point is always around 80 K regardless of the different fabrication methods and conditions used in the film growth.

FA/Mel@ZnO nanoparticles as drug self-delivery systems for RPE protection against oxidative stress

Yi, Caixia,Yu, Zhihai,Sun, Xin,Zheng, Xi,Yang, Shuangya,Liu, Hengchuan,Song, Yi,Huang, Xiao Techno-Press 2022 Advances in nano research Vol.13 No.1

Drug self-delivery systems can easily realize combination drug therapy and avoid carrier-induced toxicity and immunogenicity because they do not need non-therapeutic carrier materials. So, designing appropriate drug self-delivery systems for specific diseases can settle most of the problems existing in traditional drug delivery systems. Retinal pigment epithelium is very important for the homeostasis of retina. However, it is vulnerable to oxidative damage and difficult to repair. Worse still, the antioxidants can hardly reach the retina by non-invasive administration routes due to the ocular barriers. Herein, the targeted group (folic acid) and antioxidant (melatonin) have been grafted on the surface of ZnO quantum dots to fabricate a new kind of drug self-delivery systems as a protectant via eyedrops. In this study, the negative nanoparticles with size ranging in 4~6 nm were successfully synthesized. They could easily and precisely deliver drugs to retinal pigment epithelium via eyedrops. And they realized acid degradation to controlled release of melatonin and zinc in retinal pigment epithelium cells. Consequently, the structure of retinal pigment epithelium cells were stabilized according to the expression of ZO-1 and β-catenin. Moreover, the antioxidant capacity of retinal pigment epithelium were enhanced both in health mice and photic injury mice. Therefore, such new drug self-delivery systems have great potential both in prevention and treatment of oxidative damage induced retinal diseases.

Xiangqiang Zhong,Caixia Liu,Zhimin Di,Huajie Fang 한국정밀공학회 2020 International Journal of Precision Engineering and Vol.21 No.10

In order to improve the precision positioning accuracy of image stabilization mechanism, a two-dimensional image stabilization mechanism with parallel decoupling was proposed. Firstly, according to the principle of lever-half-bridge hybrid amplifi cation mechanism, the structure of two-dimensional image stabilization mechanism was designed, the working principle was analyzed, and natural frequency of the mechanism was calculated. Secondly, static analysis, modal analysis, and fl exure hinge parameter optimization of the mechanism based on ANSYS were carried out. The simulation results show that two-dimensional image stabilization mechanism can realize the micro-displacement positioning function in the X and Y directions. The resonance phenomenon does not occur when the mechanism works. The thickness and width are the sensitive parameters of fl exure hinge. Finally, the actuation performance of two-dimensional image stabilization mechanism was tested during the prototype, the relationship between the output displacement in the X and Y directions and the input voltage, frequency was tested, and the displacement coupling in the X and Y directions was tested. The experimental results show that the motion displacement of the mechanism is 103.9 × 104.8 μm, and the output displacement coupling does not exceed 7.5% of the stroke. The image stabilization mechanism can realize large stroke and precision positioning functions, and is feasible in engineering applications.

Zhan, Jinshun,Liu, Mingmei,Wu, Caixia,Su, Xiaoshuang,Zhan, Kang,Zhao, Guo qi Asian Australasian Association of Animal Productio 2017 Animal Bioscience Vol.30 No.9

Objective: The effect of flavonoids from alfalfa on the microbial flora was determined using molecular techniques of 16S ribosome deoxyribonucleic acid (rDNA) analysis. Methods: Four primiparous Holstein heifers fitted with ruminal cannulas were used in a $4{\times}4$ Latin square design and fed a total mixed ration to which alfalfa flavonoids extract (AFE) was added at the rates of 0 (A, control), 20 (B), 60 (C), or 100 (D) mg per kg of heifer BW. Results: The number of operational taxonomic units in heifers given higher levels of flavonoid extract (C and D) was higher than for the two other treatments. The Shannon, Ace, and Chao indices for treatment C were significantly higher than for the other treatments (p<0.05). The number of phyla and genera increased linearly with increasing dietary supplementation of AFE (p<0.05). The principal co-ordinates analysis plot showed substantial differences in the microbial flora for the four treatments. The microbial flora in treatment A was similar to that in B, C, and D were similar by the weighted analysis. The richness of Tenericutes at the phylum level tended to increase with increasing AFE (p = 0.10). The proportion of Euryarchaeota at the phylum level increased linearly, whereas the proportion of Fusobacteria decreased linearly with increasing AFE supplementation (p = 0.04). The percentage of Mogibacterium, Pyramidobacter, and Asteroleplasma at the genus level decreased linearly with increasing AFE (p<0.05). The abundance of Spirochaeta, Succinivibrio, and Suttonella at the genus level tended to decrease linearly with increasing AFE (0.05<p<0.10). Conclusion: Including AFE in the diet of dairy cows may alter the microbial composition of the rumen; however its effect on nutrient digestibility remains to be determined.

Research on 5G Core Network Trust Model Based on NF Interaction Behavior

Zhu, Ying,Liu, Caixia,Zhang, Yiming,You, Wei Korean Society for Internet Information 2022 KSII Transactions on Internet and Information Syst Vol.16 No.10

The 5G Core Network (5GC) is an essential part of the mobile communication network, but its security protection strategy based on the boundary construction is difficult to ensure the security inside the network. For example, the Network Function (NF) mutual authentication mechanism that relies on the transport layer security mechanism and OAuth2.0's Client Credentials cannot identify the hijacked NF. To address this problem, this paper proposes a trust model for 5GC based on NF interaction behavior to identify malicious NFs and improve the inherent security of 5GC. First, based on the interaction behavior and context awareness of NF, the trust between NFs is quantified through the frequency ratio of interaction behavior and the success rate of interaction behavior. Second, introduce trust transmit to make NF comprehensively refer to the trust evaluation results of other NFs. Last, classify the possible malicious behavior of NF and define the corresponding punishment mechanism. The experimental results show that the trust value of NFs converges to stable values, and the proposed trust model can effectively evaluate the trustworthiness of NFs and quickly and accurately identify different types of malicious NFs.
