How Consumers React to the Product Review Videos on Social Media Platforms : Based on the Elaboration Likelihood Model

Meng-Ying Yu,문병준 충남대학교 경영경제연구소 2022 경영경제연구 Vol.44 No.3

The purpose of this study is to explore how consumers process persuasive information from product review videos on social media platforms. We apply the elaboration likelihood model (ELM) to investigate the impacts of the central routes (information quality) and peripheral routes (characteristics of product reviewers and video popularity) on perceived persuasiveness. Additional to this study is examining the consumer involvement as a moderator between central and peripheral routes and perceived persuasiveness. The study sample consisted of 314 respondents from China. The results show that both routes substantially impact consumers' perceptions related to persuasive information and result in intentions of behavior. Moreover, the relationship between video popularity and perceived persuasiveness is positively moderated by consumer involvement. Our findings not only help the scholars understand the persuasive process in product review videos, but also assist the marketers and product reviewers in developing a better product marketing strategy on social media platforms.

Influencing Factors on User Loyalty to WeChat Channels: Focused on Mediating Role of Platform Attachment

Meng-Ying Yu,문병준 충남대학교 경영경제연구소 2022 경영경제연구 Vol.44 No.1

WeChat Channels is a well-known short video platform in China. Competition in the short video platform market is getting more intense day by day. Moreover, loyalty is an essential factor for gaining a long-term competitive advantage. Thus, we aim to explore the influencing factors that drive user loyalty to WeChat Channels in this study. Building on the Uses and Gratifications Theory(U & G) approach and attachment theory, we proposed a theoretical framework to understand how content gratification(self-documentation), social gratification(social interaction), process gratification(entertainment), and technology gratification(medium appeal) impact loyalty to WeChat Channels through platform attachment. We collected 321 responses from China through an online survey. According to the findings, social gratification(social interaction), process gratification(entertainment), and technology gratification(medium appeal) all have a positive impact on platform attachment, which in turn enhances user loyalty to WeChat Channels. The findings enrich the existing literature on short video platforms while also providing critical implications for platform operators to facilitate user loyalty.

Objective: To create genetically modified goat as a biopharming source of recombinant human lacotoferrin (hLF) with transcription activator-like effector nucleases. Methods: TALENs and targeting vector were transferred into cultured fibroblasts to insert hLF cDNA in the goat beta-lactoglobulin (BLG) locus with homology-directed repair. The gene targeted efficiency was checked using sequencing and TE7I assay. The bi-allelic gene targeted colonies were isolated and confirmed with polymerase chain reaction, and used as donor cells for somatic cell nuclear transfer (SCNT). Results: The targeted efficiency for BLG gene was approximately 10%. Among 12 Bi-allelic gene targeted colonies, five were used in first round SCNT and 4 recipients (23%) were confirmed pregnant at 30 d. In second round SCNT, 7 (53%), 4 (31%), and 3 (23%) recipients were confirmed to be pregnant by ultrasound on 30 d, 60 d, and 90 d. Conclusion: This finding signifies the combined use of TALENs and SCNT can generate bi-allelic knock-in fibroblasts that can be cloned in a fetus. Therefore, it might lay the foundation for transgenic hLF goat generation and possible use of their mammary gland as a bioreactor for large-scale production of recombinant hLF.

The epizootic disease caused by Apis cerana sacbrood virus (AcSBV) occurred in Eastern hive bee, A. cerana, since2015 in Taiwan. A large-scale survey of this disease from September and December 2016 in Taiwan was performedincluding symptom check and molecular identification in honey bees of A. cerana hives and several A. mellifera hives, which were co-cultured with A. cerana. Based on the nucleotide sequences of partial VP1, thephylogenetic analysis with those of the known AcSBV isolates revealed that most of AcSBV isolates from Taiwanwere closely relative to SBV-FZ and -JL isolates from China, whereas only one sample (N15-5-1) was in a distinctcluster, which was closely relative to SBV-LN from China too. The AcSBV prevalence was occurring in A. ceranahives in most areas of Taiwan except for those in Hualien and Pingtung Counties in Taiwan. Notably, the AcSBVprevalence rate showed the temporal increase from 47.1% to 69.6% within 4 months. In addition, 37.5% ofAcSBV prevalence rate was found in A. mellifera hives. It showed that A. mellifera was also susceptible to AcSBVinfection. The present results would provide the information on the epidemiology and for prospective research.

Yu Liu,Zhi Xin Wu,Hua Zhou,Han Zheng Nan Yu,Xiao Pan An,Jing Yuan Li,Meng Liang Li 한국자동차공학회 2020 International journal of automotive technology Vol.21 No.5

Driving cycles provide a basis for vehicle development and calibration and also serves as the foundation for energy consumption and emissions certification of vehicles. This paper presents the China Light-Duty Vehicle Test Cycle (CLTC) developed by the China Automotive Technology & Research Center (CATARC). First, the important steps and technical routes toward the CLTC development process are summarized. Second, the specific CLTC development process is presented in detail, including the data acquisition and data analysis procedures, weighting factor development and driving cycle construction. Then, the main driving characteristics of the New European Driving Cycle (NEDC), the Worldwide Harmonized Light-Duty Vehicles Test Cycle (WLTC), the Federal Test Procedure (FTP-75), the CLTC and the actual collected data are compared. The CLTC has low average speed, a high idle speed ratio and more frequent acceleration and deceleration characteristics. Finally, 70 vehicles are t ested based on the NEDC, WLTC, and CLTC according to their legislative procedures in the vehicle emission laboratories of the CATARC and the manufacturers. The results show that the CLTC’s fuel consumption is much higher than that of the NEDC and WLTC, and CLTC can effectively reflect the actual fuel consumption of users.

Background: This article aims to compare and analyze the contents of ginsenosides in ginseng ofdifferent plant ages from different localities in China. Methods: In this study, 77 fresh ginseng samples aged 2e4 years were collected from 13 differentcultivation regions in China. The content of eight ginsenosides (Rg3, Rc, Rg1, Rf, Rb2, Rb1, Re, and Rd) wasdetermined using rapid resolution liquid chromatography coupled with quadrupoleetime-of-flighttandem mass spectrometry (RRLC-Q-TOF MS/MS) to comparatively evaluate the influences of cultivationregion and age. Results: Ginsenoside contents differed significantly depending on age and cultivation region. The contentsof ginsenosides Re, Rc, Rg1, Rg3, and Rf increased with cultivation age, whereas that of ginsenoside Rb1peaked in the third year of cultivation. Moreover, the highest ginsenoside content was obtained fromChangbai (19.36 mg/g) whereas the lowest content was obtained from Jidong (12.05 mg/g). Ginseng fromJilin Province contained greater total ginsenosides and was richer in ginsenoside Re than ginseng of thesame age group in Heilongjiang and Liaoning provinces, where Rb1 and Rg1 contents were relatively high. Conclusion: In this study, RRLC-Q-TOF MS/MS was used to analyze ginsenoside contents in 77 ginsengsamples aged 2e4 years from different cultivation regions. These patterns of variation in ginsenosidecontent, which depend on harvesting location and age, could be useful for interested parties to chooseginseng products according to their needs.

The purpose of this study is to examine how the characteristics of TLSS (Taobao live streaming shopping) and subjective norm influence live streaming shopping usage intentions in e-commerce. We apply the flow theory and the TRA (Theory of reasoned action) to investigate the effects of perceived enjoyment, trust, interactivity, immediacy on attitude toward using TLSS, and the impact of subjective norm on intention to use TLSS. The research sample consisted of 335 respondents from China. The results show that interactivity is not significantly related to attitude toward using TLSS while perceived enjoyment, trust, and immediacy are significantly related to attitude toward using TLSS which in turn, indicate consumer’s usage intention of TLSS. Also, Subjective norm has a positive impact on TLSS usage intention. Our finding not only helps the researchers understand how the characteristics of TLSS and subjective norm influence live streaming shopping usage, but also assists the streamers and vendors in developing the better live streaming marketing strategy.
