A netnography study on branded customer experience: Evidence from the red sea

This study addresses the question of what are the underlying dimensions and messages to self and others that constitute the construct of customer experience. The study uses a netnography method to validate or refute and extend a priori concepts that the literature identifies within the context of resort-hotel brands in a Sharm El Sheikh resort in Egypt. The results identify eight dimensions (comfort, educational, hedonic, novelty, recognition, relational, safety and sense of beauty) and unique configurations of these eight dimensions that extend prior research on customer experience

Linking experience realms and experiential service brand loyalty: Determinants and outcomes for future operationalization

The concept of ‗Customer Experience‘ has evolved as an imperative area of study within the marketing discipline. Despite its importance and the positive attention this concept received during the last few years, the explanation of customer experiences have remained vague and lack a thorough theoretical foundation. This paper aims to address the gap in the literature and to facilitate better understanding of the concept of customer experience and its antecedents and consequences from the consumer perspective. The paper examines the impact of customer experience on brand loyalty via a comprehensive review of existing literature on the concept of customer experience and service brand literatures. Additionally, twelve hypotheses, which describe and explain the antecedents of customer experience and impacts upon brand loyalty within the service sector, are presented. The outcome of this paper adds novel perspective to the growing body of brand literature, particularly service brand and suggests directions for future research

Gaussian fields and Gaussian sheets with generalized Cauchy covariance structure

Two types of Gaussian processes, namely the Gaussian field with generalized Cauchy covariance (GFGCC) and the Gaussian sheet with generalized Cauchy covariance (GSGCC) are considered. Some of the basic properties and the asymptotic properties of the spectral densities of these random fields are studied. The associated self-similar random fields obtained by applying the Lamperti transformation to GFGCC and GSGCC are studied.Comment: 32 pages, 6 figure

Crowding effects in vehicular traffic

While the impact of crowding on the diffusive transport of molecules within a cell is widely studied in biology, it has thus far been neglected in traffic systems where bulk behavior is the main concern. Here, we study the effects of crowding due to car density and driving fluctuations on the transport of vehicles. Using a microscopic model for traffic, we found that crowding can push car movement from a superballistic down to a subdiffusive state. The transition is also associated with a change in the shape of the probability distribution of positions from negatively-skewed normal to an exponential distribution. Moreover, crowding broadens the distribution of cars' trap times and cluster sizes. At steady state, the subdiffusive state persists only when there is a large variability in car speeds. We further relate our work to prior findings from random walk models of transport in cellular systems.Comment: 23 pages, 11 figures, accepted for publication in PLoS ON

Applying marketing’s new dominant logic for interpreting customer experiences with brands

The concept of customer experience is evolving to an imperative area of study within the marketing discipline. Despite its importance and the positive attention this concept is receiving in the literature, the explanation of customer experiences remains vague and a thorough theoretical foundation is lacking. This paper addresses the gap in the literature and to facilitate a brand-management understanding of the concept of customer experience and its antecedents and consequences. The paper examines the impact of customer experience on brand loyalty via a comprehensive review of existing literature on the concept of customer experience and service brand literatures. Additionally, twelve propositions describe and explain the antecedents of customer experience and impacts upon brand loyalty within a service-centered marketing logic. This paper contributes a novel customer-brand experience perspective and conceptual tools relevant for further theory development and for effectively managing customer-brand relationships

The size, shape, and dynamics of cellular blebs

A cellular bleb grows when a portion of the cell membrane detaches from the underlying cortex under the influence of a cytoplasmic pressure. We develop a quantitative model for the growth and dynamics of these objects in a simple two-dimensional setting. In particular, we first find the minimum cytoplasmic pressure and minimum unsupported membrane length for a stationary bleb to nucleate and grow as a function of the membrane-cortex adhesion. We next show how a bleb may travel around the periphery of the cell when the cytoplasmic pressure varies in space and time in a prescribed way and find that the traveling speed is governed by the speed of the pressure change induced by local cortical contraction while the shape of the traveling bleb is governed by the speed of cortical healing. Finally, we relax the assumption that the pressure change is prescribed and couple it hydrodynamically to the cortical contraction and membrane deformation. By quantifying the phase space of bleb formation and dynamics, our framework serves to delineate the range and scope of bleb-associated cell motility and synthesizes a variety of experimental observations
