Non-physical consequences of the Muffin-tin-type intra-molecular potential
We demonstrate using a simple model that in the frame of muffin-tin - like
potential non-physical peculiarities appear in molecular photoionization
cross-sections that are a consequence of jumps in the potential and its first
derivative at some radius. The magnitude of non-physical effects is of the same
order as the physical oscillations in the cross-section of a two-atomic
molecule. The role of the size of these jumps is illustrated by choosing three
values of it. The results obtained are connected to the studied previously
effect of non-analytical behavior as a function of r the potential V(r)acting
upon a particle on its photoionization cross-section. In reality, such
potential has to be analytic in magnitude and first derivative function in
distance. Introduction of non-analytic features in model potential leads to
non-physical features in the corresponding cross-section - oscillations,
additional maxima etc.Comment: 11 pages, 5 figure
A Comparison of the Effects of Child Management and Planned Activities Training in Five Parenting Environments
This study compared the effects of two procedures designed to enhance the extra training effects of behavioral parent training. Twenty parents of oppositional children were randomly assigned to either a child management training condition or a combined child management plus planned activities condition. A further 10 non-problem children and their parents served as a social validation group. Observations of both parent and child behavior were conducted in each of five home observation settings (breakfast time, kindy (kindergarten) or school exit, a structured playtime, bathtime, and bedtime). Both training procedures resulted in changes in both child oppositional and parent aversive behavior in all observation settings. In addition, desired positive parenting behaviors also improved in all settings. Treatment effects were maintained in all settings at 3-month follow-up. Comparisons between oppositional children following treatment and children in the social validation group showed that they each displayed similarly low levels of oppositional behavior in all settings. The implications of the results for facilitating generalized changes in behavioral parent training are discussed
Customer emotions in service failure and recovery encounters
Emotions play a significant role in the workplace, and considerable attention has been given to the study of employee emotions. Customers also play a central function in organizations, but much less is known about customer emotions. This chapter reviews the growing literature on customer emotions in employee–customer interfaces with a focus on service failure and recovery encounters, where emotions are heightened. It highlights emerging themes and key findings, addresses the measurement, modeling, and management of customer emotions, and identifies future research streams. Attention is given to emotional contagion, relationships between affective and cognitive processes, customer anger, customer rage, and individual differences
