TL;DR: This paper first models the MCPPR as a particular bicriteria path problem involving an aggregated function of the path and relay costs, as well as a weight function, and considers a variant of this problem which takes into account all three functions separately.

TL;DR: In this article, the authors examine the possibility that the adverse effects on consumer brand attitudes engendered by the involvement of a celebrity endorser in a negative event may spill over brands of the same product category (i.e., competitors).
Abstract: The objective of the research presented in this article is to examine the possibility that the adverse effects on consumer brand attitudes engendered by the involvement of a celebrity endorser in a negative event may spill over brands of the same product category (i.e., competitors). The results of an experimental study with 165 adult consumers showed that a scandal involving an athlete endorser had a negative impact not only on the attitude toward the endorsed brand, but also on the attitude toward competitor brands. This suggests that brands strongly associated with one sport may be vulnerable in the context of a scandal falling upon a celebrity athlete endorsing one of their direct competitors.

TL;DR: This work constructively shows that a so-called compact formulation ofColumn generation has a block diagonal structure with identical subproblems, each of which contributes only one column in an integer solution and has an interpretation as reversing a Dantzig-Wolfe decomposition.
Abstract: Column generation has become a powerful tool in solving large scale integer programs. It is well known that most of the often reported compatibility issues between pricing subproblem and branching rule disappear when branching decisions are based on imposing constraints on the subproblem's variables. This can be generalized to branching on variables of a so-called compact formulation. We constructively show that such a formulation always exists under mild assumptions. It has a block diagonal structure with identical subproblems, each of which contributes only one column in an integer solution. This construction has an interpretation as reversing a Dantzig-Wolfe decomposition. Our proposal opens the way for the development of branching rules adapted to the subproblem's structure and to the linking constraints.

TL;DR: It is suggested that confrontation and avoidance are ineffective in preventing reoccurrence of incivility, and confrontation coping has promise with regards to eliciting positive outcomes such as psychological forgiveness that are beneficial to interpersonal workplace relationships.
Abstract: Workplace incivility has significant adverse consequences for targets. However, we know remarkably little about how targets of incivility cope and even less about which coping strategies are effective. Drawing on the coping process of the transactional model of stress, we examine confrontation as a form of problem-focused coping and avoidance as a form of emotion-focused coping in response to incivility. We examine the effects of these coping strategies on reoccurrence of incivility, incivility enacted by targets, psychological forgiveness, and emotional exhaustion. Focusing on the target's perspective of a series of uncivil interactions between a target and perpetrator, we conducted a 3-wave study of employees from various occupations. Employing the critical incident technique, participants reported on an incident of workplace incivility, and then answered a series of questions over 3 waves of data collection regarding their interactions with this perpetrator. Our findings suggest that confrontation and avoidance are ineffective in preventing reoccurrence of incivility. Avoidance can additionally lead to increased emotional exhaustion, target-enacted incivility, and lower psychological forgiveness. However, confrontation coping has promise with regards to eliciting positive outcomes such as psychological forgiveness that are beneficial to interpersonal workplace relationships.

TL;DR: Sentometrics as mentioned in this paper is a portmanteau of sentiment and econometrics, which is used to transform qualitative sentiment data into quantitative sentiment variables, and use those variables in an econometric analysis of the relationships between sentiment and other variables.
Abstract: The advent of massive amounts of textual, audio, and visual data has spurred the development of econometric methodology to transform qualitative sentiment data into quantitative sentiment variables, and to use those variables in an econometric analysis of the relationships between sentiment and other variables. We survey this emerging research field and refer to it as sentometrics, which is a portmanteau of sentiment and econometrics. We provide a synthesis of the relevant methodological approaches, illustrate with empirical results, and discuss useful software.
