This study examined the influence of racial identity in the longitudinal relation between perceptions of racial discrimination and psychological well-being for approximately 560 African American youth. Latent curve modeling (LCM) and parallel process multiple-indicator LCMs with latent moderators were used to assess whether perceptions of racial discrimination predicted the intercept (initial levels) and the slope (rate of change) of psychological well-being over time, and whether racial identity moderates these relations. The results indicated that African American adolescents who reported higher psychological responses to discrimination frequency levels at the first time point had lower initial levels of well-being. Regressing the slope factor for psychological well-being on the frequency of discrimination also revealed a nonsignificant result for subsequent well-being levels. 相似文献

A survey was sent to research libraries in the United States and Canada to learn about the level of effort involved in working with vendors' usage reports, how the data are used, and which data are most useful to librarians in managing electronic resources. Ninety‐two responses were received and analyzed. Lack of standards and inconsistencies in the usage data were identified as issues in effectively preparing the data for further analysis. In fact, the results showed that more time was spent acquiring, reformatting, and manipulating the data than on actually analyzing them. The number of full‐text downloads was specified as the most useful statistic for assessing the use of electronic resources. 相似文献

Recent investigations have established the importance of higher-order thinking in the acquisition and application of learning skills in diverse domains of inquiry. Such findings have implications for enhancing the quality of thinking of all children but have particular significance for those minority students who historically have not performed as well as their more economically advantaged peers. Although much has been written about the construct, research is still needed to identify the specific processes underlying higher-order thinking and to examine its use among minority populations. A principal-factors extraction with varimax rotation analysis was used in the present study to clarify the nature and function of higher-order thinking among minority students from economically disadvantaged backgrounds. The results allowed for a specification of the mental processes associated with the construct and the extent to which students reported an awareness and use of these processes in academic problem-solving situations. 相似文献

In recent literature on persons with learning disabilities (LD), speech recognition has been discussed primarily as an assistive
technology to help compensate for writing difficulties. However, prior research by the authors has suggested that in addition
to helping persons to compensate for poor writing skills, speech recognition also may enhance reading and spelling; that is,
what was designed as assistive technology appears to serve remedial functions as well. The present study was conducted to
determine whether elementary and secondary students with LD who used the technology to write self-selected compositions and
class assignments would demonstrate improvements in reading and spelling. Thirty-nine students with LD (ages 9 to 18) participated.
Nineteen participants used speech recognition 50 minutes a week for sixteen weeks, and twenty students in a control group
received general computer instruction. Results indicated that the speech recognition group showed significantly more improvement
than the control group in word recognition (p<.0001), spelling (p<.002) and reading comprehension (p<.01). Pre- and posttests on five reading-related cognitive processing measures (phonological, orthographic, semantic processing,
metacognitive reading strategies, and working memory) indicated that for the experimental group, only phonological processing
improved significantly over the treatment period when compared to controls (p<.04). Further ANCOVA suggested that growth in phonological processing was associated with significant differences among conditions
for all three academic measures: word recognition, spelling, and reading comprehension.
