We consider the problem of scheduling a maximum profit selection of jobs on m identical machines. Jobs arrive online one by one and each job is specified by its start and end time. The goal is to determine a non-preemptive schedule which maximizes the profit of the scheduled jobs, where the profit of a job is equal to its length. Upon arrival of a new job, an online algorithm must decide whethe...

We study auction design when parties cannot commit to the mechanism. The seller may change the rules of the game any (finite) number of times and the buyers choose their outside option at all stages. The mechanism is playable in truthful stratgies if the seller can commit to implement the outcomes of the mechanism. A consistency and one-deviation property are defined that characterize the selle...

Research has demonstrated that job complexity moderates the validity of general mental ability (GMA), the relationship between personality and job satisfaction, and the relationship between GMA and job satisfaction. However, no published research has investigated whether job complexity moderates the criterion validity of the Five-Factor Model (FFM) of personality for predicting job performance....

Selection of military pilots has long included the use of multiple aptitude test batteries. Although the names and appearances of the tests used in pilot selection vary, most are to a large extent measures of general cognitive ability, or g. This is consistent with the central role played by cognitive ability measures in the prediction of numerous job training (r = 0.43) and performance (r = 0....

Building on prior research (Meyer, Foster, & Anderson, 2006), the present study examined the utility of three approaches to validate the Performance Improvement Characteristics (PIC; Hogan & Rybicki, 1998). The PIC is a job analysis instrument used to assess personal characteristics important to successful job performance. Hogan Personality Inventory (HPI; Hogan & Hogan, 1995) data in seven arc...

This paper estimates the effect of involuntary job loss on smoking behavior and body weight using German Socio-Economic Panel Study data. Baseline nonsmokers are more likely to start smoking due to job loss, while smokers do not intensify smoking. Job loss increases body weight slightly, but significantly. In particular, single individuals as well as those with lower health or socioeconomic sta...

PURPOSE We investigated how job applicants' personalities influence perceptions of the structural and social procedural justice of group selection interviews (i.e., a group of several applicants being evaluated simultaneously). We especially addressed trait interactions between neuroticism and extraversion (the affective plane) and extraversion and agreeableness (the interpersonal plane). DES...

We develop a simple dynamic model of a worker’s transitions between employment and nonemployment. Our model implies that a worker finds a job at an optimal stopping time, when a Brownian motion with drift hits a barrier. The model has structural duration dependence in the job finding rate, in the sense that the hazard rate of finding a job changes during a nonemployment spell for a given worker...

Objective To design and validate a new competency based selection system to recruit general practice registrars, comprising a competency based application form, referees’ reports, and an assessment centre. Design Longitudinal predictive validity study and a matched case comparison. Setting South Yorkshire and East Midlands region, United Kingdom, comprising three deaneries. Participants 46 of 1...
