This study examined pilots' vigilance during an extended general aviation flight as measured by their capacity to exercise control over the aircraft during a planned flight. Thirty‐one qualified pilots flew a flight simulator from Wagga Wagga to Bankstown, Sydney, a distance of 207 nautical miles. The flight comprised five separate legs, although three legs were subjected to analysis. On the basis of attentional resource theory, it was hypothesised that task performance would differ based on the requirement for memory retrieval. Consistent with the hypothesis, the results revealed a deterioration in those tasks for which there was a substantial requirement for memory retrieval. Further analysis revealed that the deterioration in performance was best predicted by pilots' perception of the workload associated with the flight and their perception of their ability to exercise control over aircraft during normal conditions. The implications are discussed in terms of system design and training. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

Keeping or losing the best workers can be critical to whether an organization can maintain a competitive advantage and whether
operations in the organization run smoothly and efficiently. Simply stated, if the best workers are not retained, an organization
can be negatively affected from the operational to the strategic level. This article focuses on employee retention from the
perspective of a customer-based model. This approach considers employees as internal customers of management and the model
provides organizations ways to influence whether employees decide to stay or go. Additionally, the model distinguishes retention
practices based upon the value of employees to the organization. Measurement and application issues are identified along with
directions for future research. 相似文献

The Internet has changed many Human Resource (HR) practices, and techniques such as online job postings and testing have become
quite common in HR. However, the use of social networking websites such as Facebook, MySpace, LinkedIn, and Twitter for recruiting,
hiring, or terminating individuals is relatively new, but their use for these purposes is clearly growing while research on
these practices is lacking. Many questions about using these sites for HR practice have yet to be addressed, including questions
about the validity and usefulness of information obtained on these sites, applicant perceptions of employers’ use of these
sites, and the legality of using these sites, among others. The current study describes issues associated with using social
networking websites for recruiting, staffing/selection, and discipline/termination, and provides recommendations for future
research studies in this area. 相似文献

Elman (2009) proposed that the traditional role of the mental lexicon in language processing can largely be replaced by a theoretical model of schematic event knowledge founded on dynamic context-dependent variables. We evaluate Elman's approach and propose an alternative view, based on dual coding theory and evidence that modality-specific cognitive representations contribute strongly to word meaning and language performance across diverse contexts which also have effects predictable from dual coding theory. 相似文献

Research has not examined whether higher rates of parole denial among inmates with mental illness (MI) are the result of the increased presence of criminal risk factors among this population. Employing a representative sample of inmates with (n = 219) and without (n = 184) MI receiving parole release decisions in 2007, this study tested whether the central eight risk factors for recidivism considered in parole release decisions intervened in the relationship between MI and parole release. MI was associated with possession of a substance use disorder, antisocial personality disorder and violent charges while incarcerated; however, these factors were not related to release decisions. MI was found to have neither a direct nor an indirect effect on release decisions. While results indicate that release decisions appear, to some extent, to be evidence-based, they also suggest considerable discretion is being implemented by parole board members in release decisions above and beyond consideration of criminal risk factors. 相似文献

Human conscious awareness is commonly seen as the climax of evolution. However, what function-if any-it serves in human behavior is still debated. One of the leading suggestions is that the cardinal function of conscious awareness is to integrate numerous inputs-including the multitude of features and objects in a complex scene-across different levels of analysis into a unified, coherent, and meaningful perceptual experience. Here we demonstrate, however, that integration of objects with their background scenes can be achieved without awareness of either. We used a binocular rivalry technique known as continuous flash suppression to induce perceptual suppression in a group of human observers. Complex scenes that included incongruent objects escaped perceptual suppression faster than normal scenes did. We conclude that visual awareness is not needed for object-background integration or for processing the likelihood of an object to appear within a given semantic context, but may be needed for dealing with novel situations. 相似文献

The effectiveness of fixed-time delivery of attention to increase the on-task behavior of 2 students in general education
was examined. The teacher in this study provided attention to students on a 5-min fixed-time schedule and responded to students
in her typical manner between cued intervals. An ABAB withdrawal design was used to test the effects of the intervention.
The results of this study indicate that a fixed-time schedule of attention was effective in increasing students’ on-task behavior
and decreasing their off-task behavior. Implications of the study for research and practice are discussed. 相似文献

This article examines the contemporary phenomenon of imagining a world from which people have been removed. Such a trend speaks to a utopian impulse, but one that is not comparable to traditional utopian ideas. What does the popularity of books like The World without Us or documentaries such as The Future is Wild, Aftermath: Population Zero, and Life after People say about the current status of utopian ideals, environmental thought, and our cultural understanding of humanity's place in the nature order? 相似文献
