Epitaxial growth of CdSe has been achieved on (111) GaAs by electrodeposition from an aqueous electrolyte. The structure of the film corresponds to the cubic modification of CdSe. The quality of epitaxy has been investigated by reflection high-energy electron diffraction, transmission electron microscopy and X-ray diffraction techniques. 相似文献

The aim of this study was to examine the relationship between religiosity and phonatory behavior. A total of 186 participants participated in a survey that included four sections: demographic data, extent of religiosity, history of dysphonia, phonatory behavior and laryngeal manipulation, in addition to the Voice Handicap Index (VHI-10). There was no significant association between the prevalence of phonatory symptoms and any of the religiosity questions. There was no significant association between phonatory behavior, history of laryngeal manipulation and any of the religiosity questions. There was also no significant association between the score of the Voice Handicap Index and any of the five religiosity questions. There is no association between religiosity and prevalence of phonatory disturbances, phonotraumatic behavior and/or history of laryngeal manipulation. 相似文献

A pure tone changing continuously in intensity shows sweep-induced fading (SIF) of loudness as intensity sweeps down and may show a lesser degree of sweep-induced enhancement (SIE) as intensity sweeps up (Canévet & Scharf, 1990); the former effect has been calleddecruitment, the latterupcruitment. An opposite effect—upsweeps being judged to show more loudness change than downsweeps—has been reported by Neuhoff (1998). These disparate results might stem from several procedural differences. We found that differences in the sweep’s duration and intensity level did not account for the disparity, nor did the presence of a steady tone preceding the sweep. In a second experiment, direct judgments of sweep size, such as those Neuhoff’s (1998) listeners made, were affected not only by sweep size itself, but also by the intensity at the end of the sweep. The latter effect was especially marked for upsweeps. Neuhoff’s (1998) proposed “bias for rising intensities” was found only with a method for judging sweep size that is more sensitive to end level than to sweep size. 相似文献

Neuroendocrine regulation and physical and relational aggression: the moderating roles of child maltreatment and gender 总被引:1,自引:0,他引:1
The purpose of the present investigation was to examine the association between circadian rhythms of cortisol and physical and relational aggression. Morning arrival, prelunch, and afternoon predeparture salivary cortisol were assessed among 418 maltreated and nonmaltreated children (52% maltreated; 49% female) attending a summer day camp. Counselors and peers rated participants' involvement in physically and relationally aggressive behaviors. Results indicated that physical aggression was associated with heightened cortisol following morning arrival and relatively steep declines in cortisol over the day, whereas relational aggression was associated with low cortisol following morning arrival and blunted diurnal change in cortisol. Moreover, maltreatment was a significant moderator of this relationship such that aggression was related to greater cortisol dysregulation among nonmaltreated than among maltreated children. The findings suggest that physiological correlates of aggression may differ for physical and relational forms of aggression and among maltreated versus nonmaltreated populations. 相似文献

Norms for three visual memory tasks, including Corsi's block tapping test and the BEM 144 complex figures and visual recognition, were developed for neuropsychological assessment in Brazilian children. The tasks were measured in 127 children ages 7 to 10 years from rural and urban areas of the States of S?o Paulo and Minas Gerais. Analysis indicated age-related but not sex-related differences. A cross-cultural effect was observed in relation to copying and recall of Complex pictures. Different performances between rural and urban children were noted. 相似文献

Phonological awareness is strongly related to reading ability, but reports are more conflicting concerning the association of high level oculomotor skills with reading. Here, we show that phonological awareness is specifically associated with the ability to perform smooth pursuit eye movements in preschool children. Two large independent samples of preschool children (n=838 and n=732) aged 5-6.4 years, without history of neurological disorder, were examined by school medical doctors for visual and oculomotor problems. Nineteen percent of the children in the first sample and 14% in the second failed at the clinical evaluation of smooth pursuit eye movements, and 17 and 15%, respectively, presented another visual or oculomotor problem. Ten short cognitive tests were performed by the same children. Visual and oculomotor problems other than a failure on smooth pursuit were not consistently related to the cognitive tasks, with one exception, the visual recognition of letters. Children who failed at smooth pursuit obtained lower scores at a number of cognitive tasks, and especially phonological awareness tasks and copy of visually presented trajectories. Poor working memory and/or failure of anticipation during the tracking of a visual or auditory stimulus related to frontal cortex immaturity may explain these associations in preschool children. 相似文献
