Determinants of fairness-based and favorability-based reactions to authorities' decisions

The present thesis focuses on the causal role of the people's relationship to the authority in reactions to allocation decisions. A series of experiments investigating the effects of the authority's group membership on reactions to allocation decisions are reported. In addition, psychological processes that may contribute to differences in responses to ingroup versus outgroup authorities' decisions are examined. Because resource allocations across group boundaries may be particularly challenging for authorities, and because the psychological processes guiding reactions to outgroup authorities' decisions have received very little attention, a primary aim is to examine the psychology of reactions to outgroup authorities' decisions. Results demonstrate that people react more strongly to the favourability of procedures and outcomes when the authority is from an outgroup (vs. ingroup). By contrast, people generally react more strongly to the fairness of procedures when the authority is from an ingroup (vs. outgroup). Notably, direct activation of relational (ingroup) versus instrumental (outgroup) concerns produces the same response patterns as manipulating the authority's group membership. Results further suggest that responses to outgroup authorities' decisions in part can be explained by expectations that the authority is biased of members of his/her own groupUniversity of Skovde (Zweden)Social decision makin

Emotions in context: examining pervasive affective sensing systems, applications, and analyses

Pervasive sensing has opened up new opportunities for measuring our feelings and understanding our behavior by monitoring our affective states while mobile. This review paper surveys pervasive affect sensing by examining and considering three major elements of affective pervasive systems, namely; “sensing”, “analysis”, and “application”. Sensing investigates the different sensing modalities that are used in existing real-time affective applications, Analysis explores different approaches to emotion recognition and visualization based on different types of collected data, and Application investigates different leading areas of affective applications. For each of the three aspects, the paper includes an extensive survey of the literature and finally outlines some of challenges and future research opportunities of affective sensing in the context of pervasive computing

Regularity of Cauchy horizons in S2xS1 Gowdy spacetimes

We study general S2xS1 Gowdy models with a regular past Cauchy horizon and prove that a second (future) Cauchy horizon exists, provided that a particular conserved quantity $J$ is not zero. We derive an explicit expression for the metric form on the future Cauchy horizon in terms of the initial data on the past horizon and conclude the universal relation A\p A\f=(8\pi J)^2 where A\p and A\f are the areas of past and future Cauchy horizon respectively.Comment: 17 pages, 1 figur

Intermediate inflation and the slow-roll approximation

It is shown that spatially homogeneous solutions of the Einstein equations coupled to a nonlinear scalar field and other matter exhibit accelerated expansion at late times for a wide variety of potentials $V$. These potentials are strictly positive but tend to zero at infinity. They satisfy restrictions on $V'/V$ and $V''/V'$ related to the slow-roll approximation. These results generalize Wald's theorem for spacetimes with positive cosmological constant to those with accelerated expansion driven by potentials belonging to a large class.Comment: 19 pages, results unchanged, additional backgroun

Influence of radial depth of cut on entry conditions and dynamics in face milling application

In this study, acceleration of the workpiece is measured for different radial depths of cut and cutting edge geometries. The influence of the radial depth of cut on the dynamical behavior is evaluated in time and frequency domains. The results for different radial depths of cut and cutting geometries are quantified using the root mean square value of acceleration. The outcome of this research study can be used both for the better cutting data recommendations and improved tool design.У даному дослідженні прискорення оброблюваної деталі вимірювали для різних радіальних глибин різання і геометрії ріжучої кромки фрези.
