Ethics in e-commerce is one of the most crucial factors that significantly influence consumer behavior. Hitherto, most of the studies have been executed in developed countries while few research has been conducted in developing countries. The main aim of this research is to explore the roles of e-retailers' ethics to fit in with the development in developing countries. To reach this end, this research developed and tested a research model that explains the relationship between consumers' perception regarding the ethics of online retailers (CPEOR) and consumer repurchase intention (RPI). Partial least squares (PLS) approach with data collected from a survey of 518 online shoppers in Vietnam was employed to test this research model. The results showed that CPEOR has an indirect effect on consumer RPI through the mediation of consumer trust and perceived uncertainty. Furthermore, this research concretized the moderating effect of consumer online shopping habit in the relationship between RPI and its determinants.

Purpose The purpose of this paper is to examine the effects of social media-based brand community (SMBBC) markers on customer-based brand equity (CBBE). Moreover, this research evaluates the mediating effect of brand community commitment and the moderating effect of customer gender. Design/methodology/approach This research collected data from a questionnaire survey with participants who are members of the Xiaomi Community in Vietnam on Facebook (XCVF). Finally, 512 valid and usable questionnaires were tested by applying the structural equation modeling approach. Findings On the basis of social identity theory, results showed that three components of brand community markers significantly affect two aspects of CBBE. Moreover, brand community commitment plays a mediating role in the relationship of shared consciousness, ritual and traditions, and CBBE. In addition, the influence of SMBBC on CBBE is stronger for women than for men. Research limitations/implications The sample selected is limited to only members of XCVF, so the results may have an inadequate view in comparison with other brand communities. This research can eliminate other important variables that can contribute to this relationship. Originality/value This research is among the first studies that have focused on the importance of SMBBC markers on CBBE, the mediating role of brand community commitment and the moderating effect of customer gender.

Background. Clonorchis sinensis/Opisthorchis viverrini and minute intestinal flukes (MIF) such as Haplorchis pumilio and H. taichui are fish-borne trematodes (FBT) that may coexist in regions where local people have a habit of eating raw fish like Vietnam. Responses to FBT should be verified according to the data on the distribution of these flukes. This study aims to explore the prevalence of different species of FBT and related factors among local people in a northern province of Vietnam. Methods. A cross-sectional study was conducted in Kim Son and Yen Khanh districts, Ninh Binh province, between March 2016 and March 2017. Four hundred people aged 15 years or older were interviewed and gave stool samples. The FBT eggs in faecal samples were enumerated by modified formalin-ether technique and identified by sequencing of the second internal transcribed spacer (ITS2) region. Result. Among the 400 persons, 19.5% were infected with FBT. On univariate analysis, eating raw fish was the main risk factor (odds ratios (OR)) of 6.769 (95% confidence interval (CI) of 2.655–17.259) followed by being of male gender (3.994 (CI95% 2.117–7.536)) and drinking alcohol (2.680 (CI95% 1.440–4.986)), respectively. There was no risk of increased infection among those living at home without hygienic latrines, those living close to rivers or having ponds, or those raising cats or dogs. By multivariate analysis, FBT infection was only related to the consumption of raw fish and gender. Seventy stool samples with a sufficient amount of faecal matter were subjected to DNA extraction, 42.85% of them yielded DNA production, and all were of Clonorchis sinensis. Conclusion. Results of the study showed the high prevalence of infection of fish-borne trematode, mostly C. sinensis among humans in Ninh Binh province. The prevention of FBT should be strengthened with programs detailed according to the distribution of FBT in different endemic areas.
