First, it stands out as one of the earliest endeavors to employ the Hunt-Vitell theory of ethics in elucidating consumers\u2019 intention to spread NWOM on SNS. Second, this study uncovers cultural determinants shaping the intention to disseminate NWOM on SNS. Specifically, it identifies novel factors influencing the intention to spread NWOM through the mediating effects of ethical evaluations from a cultural perspective, such as belief in karma, uncertainty avoidance, and self-construal. Third, this study offers a pioneering examination of the moderating role of fear of negative evaluation. The effort helps to extend the understanding of the boundary conditions within the H-V model that either enables or constrains the impact of ethical ideology on intention to spread NWOM on SNS. Finally, while previous studies in NWOM and consumer ethics have been done in developed countries, this research provides new empirical evidence on emerging markets, namely Vietnam.&nbsp;<\/p>\n\n\n\n<p><strong>Recommendations derived from the findings of the dissertation<\/strong><\/p>\n\n\n\n<p>\u2022Instead of relying solely on reactive apologies, managers should actively influence the consumer&#8217;s internal ethical calculus. The goal is to diminish the perceived deontological duty to warn the public while heightening the teleological consideration of consequences by humanizing the brand and resolving issues privately.<br>\u2022Companies should abandon the passive avoidance strategy common in Vietnam. Publicly demonstrating empathy and accountability signals to the broader community that the brand is responsive, thereby neutralizing the ethical justification for aggressive NWOM.<br>\u2022Managers should adapt their approach based on self-construal. Provide empowerment and autonomy to customers with a strong independent self, while using community-centric rhetoric to appeal to those with a strong interdependent self.<br>\u2022To address belief in karma, firms should build a long-term reputation for fairness and CSR. To simultaneously satisfy high-uncertainty avoidance customers, managers should frame service recovery as a structured, collaborative process with clear and transparent feedback channels.<br>\u2022Managers should create safe, moderate online spaces that reduce the social fear of complaining. By ensuring respectful dialogue and offering anonymity options, brands can transform potentially destructive public criticism into constructive private conversations.<\/p>\n\n\n\n<p><strong><em>T\u00c0I LI\u1ec6U \u0110\u00cdNH K\u00c8M<\/em><\/strong><\/p>\n\n\n\n\n\n<p class=\"has-text-align-right\"><em>Ngu\u1ed3n: Vi\u1ec7n \u0110T S\u0110H, NEU<\/em><\/p>","protected":false},"excerpt":{"rendered":"<p>\u0110\u1ea1i h\u1ecdc Kinh t\u1ebf Qu\u1ed1c d\u00e2n t\u1ed5 ch\u1ee9c l\u1ec5 b\u1ea3o v\u1ec7 lu\u1eadn \u00e1n ti\u1ebfn s\u0129 cho NCS Nguy\u1ec5n Minh H\u00f2a, chuy\u00ean ng\u00e0nh Qu\u1ea3n tr\u1ecb kinh doanh (E-PHD), v\u1edbi \u0111\u1ec1 t\u00e0i:Antecedents of intention to spread negative word-of-mouth on social networking sites ORIGINAL CONTRIBUTIONS OF THE DISSERTATION Dissertation title:&nbsp;Antecedents of intention to spread negative word-of-mouth on social&#8230;<\/p>","protected":false},"author":3,"featured_media":16291,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[56],"tags":[],"class_list":["post-16296","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-dao-tao-e-phd"],"_links":{"self":[{"href":"https:\/\/isd.neu.edu.vn\/en\/wp-json\/wp\/v2\/posts\/16296","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/isd.neu.edu.vn\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/isd.neu.edu.vn\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/isd.neu.edu.vn\/en\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/isd.neu.edu.vn\/en\/wp-json\/wp\/v2\/comments?post=16296"}],"version-history":[{"count":1,"href":"https:\/\/isd.neu.edu.vn\/en\/wp-json\/wp\/v2\/posts\/16296\/revisions"}],"predecessor-version":[{"id":16298,"href":"https:\/\/isd.neu.edu.vn\/en\/wp-json\/wp\/v2\/posts\/16296\/revisions\/16298"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/isd.neu.edu.vn\/en\/wp-json\/wp\/v2\/media\/16291"}],"wp:attachment":[{"href":"https:\/\/isd.neu.edu.vn\/en\/wp-json\/wp\/v2\/media?parent=16296"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/isd.neu.edu.vn\/en\/wp-json\/wp\/v2\/categories?post=16296"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/isd.neu.edu.vn\/en\/wp-json\/wp\/v2\/tags?post=16296"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
