The study investigated the moderating role of occupational self-efficacy and job social support on the relationship between job demands and psychological well-being among mid-career academics. Participants were 203 academics at three public Nigerian universities (female = 37.93%; mean years of service = 8.58 years, SD = 2.20). The academics completed measures of job demands, occupational self-efficacy, job social support, and psychological well-being. Moderated regression analysis of the data suggested only occupational self-efficacy to moderate the relationship between work demands and psychological well-being. Findings underpin the buffering effects of work self-efficacy in employee psychological well-being with high job demands. 相似文献

This study evaluated the extent to which two microswitches used as interfaces would enable a man with multiple disabilities and limited motor behavior to operate an electric door opener at the entrance of the day center that he attended. Analysis showed the man (a) learned to use the two microswitches, (b) preferred the microswitch placed at his wheelchair's footrest (which also allowed more effective responding) over the microswitch placed at his wheelchair's armrest, and (c) maintained his positive performance at the 1- and 2-mo. postintervention checks. The results were discussed from a technical and practical standpoint and in terms of implications for the quality of life of persons with disabilities. 相似文献

This study examined whether Project Support, a parenting intervention shown to reduce child conduct problems, also exerts
positive effects on features of psychopathy in children. Participants were 66 families (mothers and children) recruited from
domestic violence shelters who participated in a randomized controlled trial evaluating Project Support. Each family included
at least one child between the ages of 4 and 9 who was exhibiting clinical levels of conduct problems. Families were randomly
assigned to the Project Support intervention condition or to an existing services comparison condition, and they were assessed
on 6 occasions over 20 months, following their departure from the shelter. Children in families in the Project Support condition,
compared with those in the comparison condition, exhibited greater reductions in features of psychopathy. Moreover, the changes
in features of psychopathy remained after accounting for changes in conduct problems. Project Support’s effects on features
of psychopathy were mediated by improvements in mothers’ harsh and inconsistent parenting. These findings on the effects of
an intervention on features of psychopathy are the first from a randomized controlled trial. They inform the debate about
whether features of psychopathy in children are responsive to intervention, and hold important implications for clinical practice. 相似文献

In two previous studies, the perception of speech rate was found to be positively related to the vocal frequency and intensity of speech. In those studies, a single sample of spontaneous, content-masked speech was used to produce nine stimuli by factorially varying three levels of each vocal frequency and intensity, while controlling the actual speech rate of the stimuli. Participants were asked to judge each stimulus, preceded by a standard, “anchoring,” stimulus as to its speech rate, pitch, loudness, and duration. The purpose of the three studies reported here was to examine the generalizability of the previous findings by using stimuli that were nonmasked and/or were not preceded by an anchoring stimulus. In each study, nine speech stimuli were prepared, as described above, and participants were asked to make judgments about the rate, pitch, loudness, and duration of each stimulus. In the first study, the stimuli were masked but were not preceded by an anchoring stimulus. In the second study, participants listened to content-standard speech stimuli preceded by an anchoring stimulus. Finally, in the third study, content-standard stimuli without an anchoring stimulus were used. In addition, studies two and three used speech segments of a male and a female speaker. The findings from the three studies replicated the central findings of the previous studies. They suggest, in other words, that rate perception of speech is indeed influenced by vocal frequency and, to some extent, by intensity, and that these relationships are not materially altered by the speakers'gender. 相似文献
