"Pardonner ou se venger ?" : le rôle de l'affectif dans le processus psychologique de vengeance du client

La vengeance du client devient actuellement un phénomène prépondérant dans nos sociétés (Grégoire et al., 2010). Un client insatisfait pourrait, sans surprise, punir l’entreprise via des actions de vengeance. Or, il n’est guère attendu qu’un client fidèle s’engage également dans ce type d’action alors qu’il entretient une bonne relation avec la marque. Ce travail doctoral propose d’étudier le processus psychologique de la vengeance du client, notamment de ceux ayant une bonne relation avec l’entreprise. Pour ce faire, l’état de l’art sur la vengeance du client complétée par une étude qualitative exploratoire triangulaire a permis de souligner l’importance des éléments affectifs dans ce processus. Ainsi, trois typologies ont été proposées à l’issue des résultats qualitatifs : (1) L’Iceberg des Crises Perçues identifie les crises de marque comme nouveau contexte déclencheur de la vengeance ; (2) Le Triangle Emotionnel du Client d’Inter-Rôle révèle deux familles d’émotions négatives ainsi que les rôles « victime vs. coupable » du client-vengeur dans ce processus ; (3) La typologie des actions de vengeance considère divers points de vue des acteurs dans sa classification. Au cours de la seconde étude, une expérimentation a été réalisée en manipulant trois facteurs : la relation affective marque-client, les émotions négatives et la gravité perçue de la crise (n=1296). Ceci a permis d’éclairer le « conflit affectif » au sein du mécanisme psychologique de vengeance du client. L’effet « l’amour pardonne tout » de la relation affective marque-client émerge seulement lorsque la crise est perçue comme étant de faible gravité. En revanche, lors d’une crise provoquant de graves conséquences et notamment lorsque le client n’est pas l’utilisateur final du produit, apparaît l'effet « l'amour devient la haine ». Plus spécifiquement, le client ayant une bonne relation avec l’entreprise est plus enclin à se venger de celle-ci. Les résultats soulignent également les effets contradictoires des émotions négatives, notamment la culpabilité et la tristesse, dans la décision de l’individu de se venger.Customer revenge has become a major phenomenon in our societies (Grégoire et al., 2010). Unsurprisingly, a dissatisfied customer can punish a company through actions of revenge. However, due to their good relationship with the brand, loyal customers are not expected to be amongst those seeking revenge. This doctoral dissertation aims at studying the psychological process of customer revenge with a focus on those who have a good relationship with the brand. Through a review of the literature on customer revenge and an exploratory qualitative study, this dissertation highlights the importance of the emotional factors in this process. Three typologies have been proposed: (1) The Iceberg of Perceived Crisis identifies brand-crisis as a new trigger of customer revenge; (2) The Triangle of Emotions of the Customer Avenger reveals two families of negative emotions and the « victim vs. perpetrator » roles of the customer avenger; (3) The third typology of actions of revenge includes the point of view of the different parties involved. In the second study an experiment has been performed by manipulating three factors: the brandcustomer emotional relationship, the negative emotions and the perceived severity of the crisis (n = 1296). The findings help to clarify the « emotional conflict » within the psychological mechanism of customer revenge. The « love is blind» effect of the customer’s emotional relationship is only present when the crisis is perceived as being of little importance. However, when a crisis causes serious consequences, particularly when the customer is not the final user of the product, the « love-becomes-hate » effect appears. Thus, a customer who has a good relationship with the brand is more inclined to seek revenge. The results of the experiment also highlight the conflicting effects of negative emotions, especially of sadness and guilt in the customer’s decision to take revenge

Assessment and Simulation of Impacts of Climate Change on Erosion and Water Flow by Using the Soil and Water Assessment Tool and GIS: Case Study in Upper Cau River basin in Vietnam

The Upper Cau river basin which plays an important role in socio-economic developments the North of Vietnam is sensitive to changes of climate influencing flows, erosion, and water resources. The main objective of this study is to assess and simulate impacts of climate change on erosion and water flow in the basin. Using a GIS database and Soil and Water Assessment Tool (SWAT) model, the water flow and soil loss were assessed with data in period 1980-1999 called the based period, then simulated until 2100 considering the medium emission scenario (B2). The simulation result showed that the total annual runoff and soil loss tends to increase compared to the base period. For flow, the change rate of the simulation period is higher than the base period; the water flow rate will increase by 0.22% (2020-2039) and up to 1.37% (2080-2100). The total annual soil loss of the simulation period at Gia Bay station tends to increase steadily compared to the baseline, namely by 6.2% (2020-2039) and 25.5% (2080-2100). Overall, the result in this study shows that effects of climate changes on the basin are severe enough under the scenario B2 which is useful for authorities for basin management.ReferencesAli R., McFarlane D., Varma S., Dawes W., Emelyanova I., Hodgson G., Charles S., 2012.

The Impact of Job Satisfaction on Job Performance of Tax Officials: An Empirical Study in Vietnam

Purpose: The level of employee satisfaction with the use of e-tax systems is a major factor influencing the success of such systems. While studies typically focus on taxpayers' perspectives, this research investigates the influence of perceived ease of use, IT background, incentives, and social influence on tax officials’ job performance, mediated by tax officials’ job satisfaction.   Theoretical framework: The research is based on the Theory of Planned Behavior (TPB) and Technology Acceptance Model (TAM) to propose the research model which analyze the impact of job satisfaction on job performance.    Design/Methodology/Approach: A quantitative approach was adopted, involving surveys administered to tax officials in Vietnam. The study analyzed 250 valid responses using Cronbach's test, Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and Structural Equation Modeling (SEM).   Findings: The research revealed that all four factors significantly influence job performance through job satisfaction of tax officials in Vietnam. These findings provide valuable insights for tax authorities to improve job performance.   Research, Practical & Social implications: The research results contribute to other countries with similar characteristics in devising strategies to enhance employee performance. However, its limitations include its generalizability to other e-tax systems and countries. Future research with a larger sample size could bolster the applicability of these findings nationally.   Originality/Value: The research suggests tax authorities to support tax officials improve their professional skills; improve the regulations, policies on salary and bonus for tax officials; assist tax officials in using the e-tax system; implement effective communication

Factors Affecting Intention to Purchase Voluntary Pension Insurance in Vietnam

The research was carried out with the aim to identify factors affecting the intention to purchase voluntary pension insurance in Vietnam. With data collected from 334 subjects across the country, mainly in Hanoi, the results showed that attitude towards risk, subjective norms, percieved behavioral control, past experiences and corporate branding have positive influences on the central factor, which is intent. After quantitative analysis, the study proposes recommendations for businesses to improve their services as well as methods of distribution to meet the needs of potential customers to save in pension funds. Additionally, the study will provide the basis for regulators to come up with measures to promote the retirement insurance market and at the same time, raise public awareness about social security.

Screening yeast strains for alcohol fermentation from the dried traditional yeast

Methods to produce rice alcohol by dried traditional yeast are unstable because the yeast system in dried traditional yeast has depended on nature and not been controlled. In this study, a total of 15 different kinds of dried traditional yeast were prepared and screened. Each yeast strain was evaluated by analyzing its fermentation property and alcohol tolerance. There are 19 yeast strains were isolated and their growth conditions and ethanol producing properties were examined. Results showed that three strains S1, BT, BL3 grew and produced ethanol at temperature 28-30oC, and pH 5-5.5. Especially, high concentration ethanol tolerance ability of the three strains was at 8-18%. Our results showed that these strains were valuable microorganisms and could be utilized as a basis for further study of dried traditional yeast in traditional alcoholic beverages
