Abstract. We present a new 3-D GPS velocity solution for 182 sites for the region encompassing the Western Alps, Pyrenees, and southern France. The velocity field is based on a Precise Point Positioning (PPP) solution, to which we apply a common-mode filter, defined by the 26 longest time series, in order to correct for network-wide biases (reference frame, unmodeled large-scale processes, etc.). We show that processing parameters, such as troposphere delay modeling, can lead to systematic velocity variations of 0.1-0.5 mm yr −1 affecting both accuracy and precision, especially for short (< 5 years) time series. A velocity convergence analysis shows that minimum time-series lengths of ∼ 3 and ∼ 5.5 years are required to reach a velocity stability of 0.5 mm yr −1 in the horizontal and vertical components, respectively. On average, horizontal residual velocities show a stability of ∼ 0.2 mm yr −1 in the Western Alps, Pyrenees, and southern France. The only significant horizontal strain rate signal is in the western Pyrenees with up to 4 × 10 −9 yr −1 NNE-SSW extension, whereas no significant strain rates are detected in the Western Alps (< 1 × 10 −9 yr −1 ). In contrast, we identify significant uplift rates up to 2 mm yr −1 in the Western Alps but not in the Pyrenees (0.1 ± 0.2 mm yr −1 ). A correlation between site elevations and fast uplift rates in the northern part of the Western Alps, in the region of the Würmian ice cap, suggests that part of this uplift is induced by postglacial rebound. The very slow uplift rates in the southern Western Alps and in the Pyrenees could be accounted for by erosion-induced rebound.

The goal of this study is to ascertain the critical elements affecting public acceptance and readiness to advocate electronic government services in Vietnam. An online survey was conducted among Vietnamese citizens. The chosen respondents had experience with e-government services. The analysis was utilized with the data gathered from 316 clean and legitimate responses. PLS-SEM analytic techniques and the SmartPLS program were adopted to execute analyzing processes. The findings indicate that three essential factors influenced the adoption of e-government services: (i) perceived service value, (ii) citizen e-empowerment, and (iii) fear of Covid-19. The perceived value of services, fear of Covid-19, and acceptance of e-government services all have a beneficial effect on citizen intention to recommend e-public services. This study suggested three practical implications: (a) leveraging the challenges of Covid-19 pandemic is to promote e-government services; (b) enhancing public service quality and informational quality is critical and vital to adopting e-government services, and (c) promoting citizen e-empowerment, outcomes, values, self-responsibility, and working procedures of e-public services to all citizens is necessary.
The current study develops a research model and explores the correlation between customer sense of online betrayal, brand hate, and anti-brand activism. The outrage customers’ anti-brand behaviors consist of negative online word of mouth, online public complaining, and online boycott. Data from an online survey of 383 online shoppers were used to test seven proposed hypotheses. The partial least square–structural equation modeling (PLS-SEM) was adopted to assess the measurement and structural model. The findings showed that the sense of online betrayal positively and significantly affects brand hate and anti-brand behaviors. In addition, brand hate is also the leading cause of customers’ anti-brand actions. The present study highlights the mediation role of brand hate in eliciting revenge from consumers subjected to online betrayal. This study also gives some recommendations to customers to stop the misconduct behaviors of online betrayals, such as spreading their betrayal cases to friends and relatives via social media, then asking for supports and help from governmental and legal agencies and participating in boycotts; raising boycott movements against the betraying brand should be considered as the most extreme punishment.
The most crucial key to successfully approaching customers is enhancing the interaction experience between customers and retailers. This study explores the motivations for adopting augmented reality (AR) in retailing small and medium-sized retailers in Vietnam. A structured questionnaire was delivered to a total sample of 302 Vietnamese retailers and got 215 clean and valid responses. The survey was conducted both online and offline for ten months, from February 2021 to December 2021. The chosen surveyors are retailing managers and owners of retailing firms. These firms sell fashion products, technology gadgets, and household products. The data were statistically analyzed using Smart PLS software and the partial least equation structural model. The findings indicate three direct, positive, and significant factors that influence the retailer’s AR adoption, including (1) organizational attitude toward AR, (2) organizational innovativeness, and (3) competition pressure in which organizational attitude toward AR and organization innovativeness are two critical motivational drivers. The competition pressure has been identified as the challenge barrier. The cost barriers affect organizational attitude toward AR but do not significantly influence AR adoption. Along with theoretical contributions, this paper also gave some theoretical and practical implications for retailers who have the intention to adopt AR and integrate AR into their current retailing system.
