Affective events are events that impact people in positive or negative ways. When people discuss an event, people understand not only the affective polarity but also the reason for the event being positive or negative. In this paper, we aim to categorize affective events based on the reasons why events are affective. We propose that an event is affective to people often because the event descri...

In recent years, dramatic increase in the cost of health care has compelled practitioners to draw a balance between improving efficiency and reducing costs. A discrete-event simulation model has been constructed to assist a typical two-physician family practice healthcare clinic in evaluating potential resource allocations to improve operating efficiencies and patient satisfaction. A performanc...

One approach for computing plans for reactive agents is is to check goal statements over state trajectories modeling predicted behaviors of an agent. This paper describes a powerful extension of this approach to handle time, safety, and liveness goals that are spec-iied by Metric Temporal Logic formulas. Our planning method is based on an incremental planning algorithm that generates a reactive...

Victim support services, in mature societies, aim to help victims recover after suffering a traumatic event. The effectiveness of victim support has traditionally been evaluated through rates of service utilization and incidence of psychopathology such as posttraumatic stress disorder. The current study, instead, inquires into service users' unmet needs and satisfaction, and identifies factors ...

The concept of procedural utility assumes that agents do not only receive utility from outcomes, but also attach an independent value to the procedures that lead to these outcomes. This paper analyzes whether the preferences that underlie procedural utility are homogeneous, using the case of independence at the workplace. I exploit the event of German reunification to assign preferences for ind...

This article reports the development of the Stress-Related Growth Scale (SRGS) and its use in a study examining determinants of stress-related positive outcomes for college students. Study 1 analyses showed that the SRGS has acceptable internal and test-retest reliability and that scores are not influenced by social desirability. Study 2 analyses showed that college students' SRGS responses wer...

Volunteers are a valuable set of human resources for any sporting event, and various studies have been conducted in different contexts to understand volunteers’ psychological characteristics. The purpose of this study is to examine the impact of motivations on individual’s volunteer satisfaction using a modified version of Bang and Chelladurai’s (2003) Volunteer Motivations Scale for Internatio...

We investigate solution techniques for numerical constraint satisfaction problems and validated numerical set integration methods for computing reachable sets of nonlinear hybrid dynamical systems in presence of uncertainty. To use interval simulation tools with higher dimensional hybrid systems, while assuming large domains for either initial continuous state or model parameter vectors, we nee...

BACKGROUND Sporting or physical recreation event participation can affect different domains of mental and social well-being if sufficiently frequent, yet previous research has focused mainly on the physical health benefits of single-location or infrequent mass-participation events. We examined overall and domain specific subjective well-being of adult participants of "parkrun", a weekly, commun...
