Based on the contention that leadership has sustained effects on followers even after the leader-follower relationship has ended, we investigated the career-long effects of abusive coach leadership on athlete aggression and task performance. Abusive leadership scores were derived from ratings by two independent raters' evaluations of coaches' biographies, and athlete aggression and task perform...

BACKGROUND Nurses often complain about overwork and underpay. It seems that the association between "quality of working life" (QWL) and the degree of nurses' involvement in their carrier is the critical factor in achieving a higher level of quality of care. This study aimed to assess the quality of working life and its association with "job performance" of the nurses in educational hospitals af...

We present a novel characterization of how a program stresses cache. This characterization permits fast performance prediction in order to simulate and assist task scheduling on heterogeneous clusters. It is based on the estimation of stack distance probability distributions. The analysis requires the observation of a very small subset of memory accesses, and yields a reasonable to very accurat...

Successful social interactions depend on the ability to anticipate other people's actions. Current conceptualizations of brain function propose that causes of sensory input are inferred through their integration with internal predictions generated in the observer's motor system during action observation. Less is known concerning how action prediction changes with age. Previously we showed that ...

This research compared ratings of task performance and contextual performance from three different sources: self, peer, and supervisor. Participants were service industry employees in the service industries in Yogyakarta, Indonesia. A Sample of 146 employees and 40 supervisors   from the service industries provided ratings of task performance and contextual performance. The results indicated th...

One in five American children grows up in poverty. Childhood poverty has far-reaching adverse impacts on cognitive, social and emotional development. Altered development of neurocircuits, subserving emotion regulation, is one possible pathway for childhood poverty's ill effects. Children exposed to poverty were followed into young adulthood and then studied using functional brain imaging with a...

Two qualitatively different information-processing algorithms for solution of Raven’s Progressive Matrices items have been identified. Whereas the Gestalt algorithm involves spatial operations upon the test stimuli, the Analytic algorithm employs logical operations upon features abstracted from the displays. In this study, training groups were established varying both in the Strength (Weak or S...

Distance metric plays an important role in machine learning which is crucial to the performance of a range of algorithms. Metric learning, which refers to learning a proper distance metric for a particular task, has attracted much attention in machine learning. In particular, multi-task learning deals with the scenario where there are multiple related metric learning tasks. By jointly training ...

1. introduction language teachers frequently observe a gap between their students' potential competence and their performance in the class. anderson (1993) attributes this to the fact that human has a limited processing capacity and is not able to attend to various aspects of a task simultaneously. this limitation causes l2 learners not to be able to focus on both meaning and form at the same t...
