It’s all relative : how customer-perceived competitive advantage influences referral intentions
Better understanding the mechanisms that influence customer intentions to spread positive word-of-mouth (WOM) is crucial to both marketing scholars and managers. This multimethod research contributes to marketing knowledge by revealing how a firm’s customer-perceived competitive advantage (CPCA) influences positive WOM intentions. Analyses of (1) cross-sectional survey data on bank customers in Germany and (2) experimental data on customers of car insurance companies in the USA reveal two crucial insights. First, CPCA influences WOM intentions in both industries, over and above numerous established antecedents of customer loyalty (e.g., satisfaction, trust, and perceived value). Second, this research demonstrates a robust and pervasive CPCA-by-satisfaction interaction effect, such that the influence of CPCA on WOM intentions increases as customer satisfaction decreases. The results show that customer-perceived competitive advantage plays an important role in shaping WOM intentions, especially among less-satisfied customers. Theoretical and managerial implications of these findings are discussed
Service Robots Rising:How Humanoid Robots Influence Service Experiences and Elicit Compensatory Consumer Responses
Interactions between consumers and humanoid service robots (HSRs; i.e., robots with a human-like morphology such as a face, arms, and legs) will soon be part of routine marketplace experiences. It is unclear, however, whether these humanoid robots (compared with human employees) will trigger positive or negative consequences for consumers and companies. Seven experimental studies reveal that consumers display compensatory responses when they interact with an HSR rather than a human employee (e.g., they favor purchasing status goods, seek social affiliation, and order and eat more food). The authors investigate the underlying process driving these effects, and they find that HSRs elicit greater consumer discomfort (i.e., eeriness and a threat to human identity), which in turn results in the enhancement of compensatory consumption. Moreover, this research identifies boundary conditions of the effects such that the compensatory responses that HSRs elicit are (1) mitigated when consumer-perceived social belongingness is high, (2) attenuated when food is perceived as more healthful, and (3) buffered when the robot is machinized (rather than anthropomorphized)
Personalized Advertising in Public Environments: Perceptions and Consequences
Grounded in theory on self-concept congruity and impression management, we examine effects of personalized advertising in public, where others are present and see the personalized content concurrently. We find an indirect effect of others' presence on consumers' attitudes and behavioral intentions, mediated by embarrassment and moderated by ad-self-concept congruity state
The Planckian Conspiracy: String Theory and the Black Hole Information Paradox
It has been argued that the consistency of quantum theory with black hole
physics requires nonlocality not present in ordinary effective field theory. We
examine the extent to which such nonlocal effects show up in the perturbative
S-matrix of string theory.Comment: 13 pages, harvma
An Evening Sector Ps 6 - Omega Band Event
Article draft. Author list indicative and roughly corresponds to amount of contribution to the article to date.Abstract. Ps 6 magnetic disturbances and associated optical
forms known as omega bands are usually associated
with the morning sector. Some evidence for similar phenomenology
in the evening sector has been presented by
Solovyev et al. (1999). We confirm and extend those results
with high time resolution magnetic and imaging observations
from Athabasca University Geophysical Observatory
for an event that took place on July 27, 2003, along with conjugate
hemisphere imaging from the Polar spacecraft. The
observed signatures indicate sunward drift (westward in the
evening sector). Magnetic perturbations feature negative Y
and transitional Z indicating westward passage of poleward
equivalent currents overhead. As has been suggested by Connors
et al. (2003) to be often the case for morning sector Ps
6/omega bands, initiation of the evening sector event coincided
with substorm onset. From optical and magnetic data
we obtain consistent results for the drift rate of the forms,
which changed during the event. An inner magnetospheric
source is suggested, with triggering of the onset by an increase
in solar wind speed

Engineering a pure Dirac regime in ZrTe5
Real-world topological semimetals typically exhibit Dirac and Weyl nodes that coexist with trivial Fermi pockets. This tends to mask the physics of the relativistic quasiparticles. Using the example of ZrTe5, we show that strain provides a powerful tool for in-situ tuning of the band structure such that all trivial pockets are pushed far away from the Fermi energy, but only for a certain range of Van der Waals gaps. Our results naturally reconcile contradicting reports on the presence or absence of additional pockets in ZrTe5, and provide a clear map of where to find a pure three-dimensional Dirac semimetallic phase in the structural parameter space of the material

Molecular dissection of the valproic acid effects on glioma cells
Many glioblastoma patients suffer from seizures why they are treated with antiepileptic agents. Valproic acid (VPA) is a histone deacetylase inhibitor that apart from its anticonvulsive effects in some retrospective studies has been suggested to lead to a superior outcome of glioblastoma patients. However, the exact molecular effects of VPA treatment on glioblastoma cells have not yet been deciphered. We treated glioblastoma cells with VPA, recorded the functional effects of this treatment and performed a global and unbiased next generation sequencing study on the chromatin (ChIP) and RNA level. 1) VPA treatment clearly sensitized glioma cells to temozolomide: A protruding VPA-induced molecular feature in this context was the transcriptional upregulation/reexpression of numerous solute carrier (SLC) transporters that was also reflected by euchromatinization on the histone level and a reexpression of SLC transporters in human biopsy samples after VPA treatment. DNA repair genes were adversely reduced. 2) VPA treatment, however, also reduced cell proliferation in temozolomide-naive cells: On the molecular level in this context we observed a transcriptional upregulation/reexpression and euchromatinization of several glioblastoma relevant tumor suppressor genes and a reduction of stemness markers, while transcriptional subtype classification (mesenchymal/proneural) remained unaltered. Taken together, these findings argue for both temozolomide-dependent and -independent effects of VPA. VPA might increase the uptake of temozolomide and simultaneously lead to a less malignant glioblastoma phenotype. From a mere molecular perspective these findings might indicate a surplus value of VPA in glioblastoma therapy and could therefore contribute an additional ratio for clinical decision making
