(Received) We calculate frequency shifts and changes in linewidths of infrared-active phonons within a shell model for the bare phononic system coupled to an electronic double-layer structure with inter-layer charge transfer. The theoretical concept is applied to YBa 2 Cu 3 O 7 yielding a good description of experimental results in the normal state as well as at the transition to the supercondu...

Thriving describes an individual’s experience of vitality and learning. The primary goal of this paper is to develop a model that illuminates the social embeddedness of employees’ thriving at work. First, we explain why thriving is a useful theoretical construct, define thriving, and compare it to related constructs, including resilience, flourishing, subjective well-being, flow, and self-actua...

This two-part investigation evaluated four different explanations potentially governing theory on deprecating speech: social identity, expectancy violation, complexity-extremity, and desensitization. To test the descriptive and predictive usefulness of the first three theories, 614 participants made attributions of the perceived harm of actual racist slurs targeted at African, Asian, or Hispani...

Most of the theoretical models describing the translocation of a polymer chain through a nanopore use the hypothesis that the polymer is always relaxed during the complete process. In other words, models generally assume that the characteristic relaxation time of the chain is small enough compared to the translocation time that nonequilibrium molecular conformations can be ignored. In this pape...

Donors in silicon hold considerable promise for emerging quantum technologies, due to their uniquely long electron spin coherence times. Bismuth donors in silicon differ from more widely studied group V donors, such as phosphorous, in several significant respects: They have the strongest binding energy (70.98 meV), a large nuclear spin (I=9/2), and a strong hyperfine coupling constant (A=1475.4...

Compulsive buying is a form of addictive consumption where consumers purchase goods that they either don’t need or can’t afford. This paper reviews the literature on this problem behavior and summarizes the findings in the following three areas: conceptual definition, reasons “why” consumers engage in this type of addictive consumption, predictors of compulsive shoppers and the correlation with...

Most theoretical models for NMR relaxation in liquids assume that overall rotational motion can be described as rotational diffusion with a single diffusion tensor. Such models cannot handle motions (such as between "closed" and "open" states of an enzyme, or between conformers of a partially disordered system) where the shape of the molecule (and hence its rotational diffusion behavior) fluctu...

We analyze standard theoretical models of solar energy conversion developed to study solar cells and photosynthetic systems. We show that assuming the energy transfer to the reaction center/electric circuit is through a decay rate or "sink", contradicts the second law of thermodynamics. We put forward a thermodynamically consistent alternative by explicitly considering parts of the reaction cen...
