Gaining Competitive Advantage through Standardization and Differentiation of Services
2015
The goal of the paper is to study the question of whether or not differences between cultural groups influence the decision of a consumer wishing to avail himself of a particular service. Therefore we have developed a semiotic extension of the means-end approach as the theoretical basis for elaborating a solution to this problem. The conjoint analysis specifies the results of the meansend analysis.
A differential-geometric approach to generalized linear models with grouped predictors
2016
We propose an extension of the differential-geometric least angle regression method to perform sparse group inference in a generalized linear model. An efficient algorithm is proposed to compute the solution curve. The proposed group differential-geometric least angle regression method has important properties that distinguish it from the group lasso. First, its solution curve is based on the invariance properties of a generalized linear model. Second, it adds groups of variables based on a group equiangularity condition, which is shown to be related to score statistics. An adaptive version, which includes weights based on the Kullback-Leibler divergence, improves its variable selection fea…
Customer value in Quick-Service Restaurants: A cross-cultural study
2020
Abstract In spite of the relativistic nature of Customer Value concept, research on differences in Value perceptions across cultures is still scarce. Gaining insight about this issue would be especially relevant for highly competitive and globalized industries such as Fast-Food or Quick-Service Restaurants (QSR). The purpose of the present paper is to identify Value dimensions in this industry and to analyze the links between dimensions of Value, Satisfaction and Loyalty, testing the consistency of the results obtained across three different countries. To achieve this aim, after one in-depth interview with a QSR manager and two intercultural focus groups with QSR customers, a questionnaire …
Emotion Eliciting Events in the Workplace: An Intercultural Comparison
2007
Different emotional experiences at the work place are evaluated in respect to their influence on job satisfaction. A sample of 75 Japanese employees and 169 German employees rated their emotional level following daily hassles in the work place that were attributed on the two dimensions: locus of causality and controllability. It was predicted that the same attribution pattern of daily hassles leads to different emotional responses and different levels of job satisfaction between employees with an interdependent and independent cultural background. Results indicate that equal attribution patterns of job related daily hassles lead to different emotional experiences between the two cultural gr…
Entextualization and resemiotization as resources for identification in social media
2014
Drawing on insights provided by linguistic anthropology, the study of multisemioticity and research in computer-mediated discourse (CMD), this chapter discusses how entextualization (Bauman & Briggs, 1990; Silverstein & Urban, 1996; Blommaert, 2005, pp. 46–8) and resemiotization (Iedema, 2003; Scollon & Scollon, 2004, pp. 101–3; Scollon, 2008) are key resources for identity work in social media. Three key arguments inspire and give direction to our discussion, each of them laying down touchstones for language scholars who wish to investigate identity in social media. First, for many individuals and social or cultural groups, social media are increasingly significant grassroots arenas for in…
