Using an updated version of the Aging Semantic Differential, 534 younger, middle age, and older participants from a college community rated female and male targets categorized as ages 21–34 and 75–85. Participants also provided views about their own aging. Repeated measures of analysis of variance examined attitudinal differences by age and gender of targets, and by participant age and gender. Female targets were viewed more positively than males by most rater groups. Older targets were viewed more positively by older participants than by other age groups. Older participants had more positive views about their own aging than did participants of younger or middle ages. 相似文献

The World Wide Web is a popular “tool” for companies. It can be used as a method of communication between companies and their customers; it also allows organizations to setup virtual storefronts that can be accessed by customers from all over the world. The ability to understand customers’ behavior is extremely important as companies strive to increase the usability and profitability of their web service. The concept of a session is a popular unit of measurement used to analyze recorded information. However, this concept is currently rather abstract and lacks definition. How we measure a session is a fundamental question for web services utilizing this concept. Currently, this question has no real answer. This paper presents a session timeout threshold model based on empirical observations as an initial answer to this question. The model seeks to provide accurate session data with respect to individual web services. 相似文献

A content analysis of the journal Religious Education: An Interfaith Journal of Spirituality, Growth and Transformation was conducted for a 10-year period between 1993–2002 (Volume 88, 1–Volume 97, 4). A total of 325 articles (277 authors) were analyzed into 3 primary research directions (theoretical, qualitative, and quantitative). Author institutional affiliation, religious identity, position, geographic location, and number of contributions were also computed. Implications for the Journal and the field of religious education are discussed. 相似文献

The objective of this study is to empirically explore the extent to which public two-year colleges in this country are characterized by open admissions policies and by comprehensive curricula, as well as the extent and nature of programs for the disadvantaged within these institutions. Utilizing a stratified sampling design developed by the research staff of the American Council on Education, a precoded original questionnaire was mailed in the spring of 1971 to the chief administrative officer for each institution in the sample. It was found that only a little over half of the colleges have the curricula offerings and admissions policies of exemplary community colleges, but that all reported special courses, programs, or services for the academically disadvantaged minority group. However, only 40% of our sample indicated that they have developed special programs (as opposed to courses or services). Too, community colleges with programs require (1) more resources in preparing faculty for dealing effectively with the disadvantaged, (2) additional emphasis on recruitment of the disadvantaged, and (3) more attention to developing courses in ethnic studies.An earlier version of this paper was presented at the annual meeting of the American Educational Research Association, New Orleans, February 1973. Partial support for the project from which this paper was developed was provided by the U.S. Office of Education (Contract #OEC-0-70-4283 (399) to the Pennsylvania State Department of Education). The author also wishes to acknowledge the contribution of Reynolds Ferrante, graduate student, Pennsylvania State University, who assisted in the literature review and questionnaire development of the project. 相似文献

The effects that item order and basal and ceiling rules have on test means, variances, and internal consistency estimates for the PIAT mathematics and reading recognition subtests were examined. Seven items on the math subtest and one item on the reading recognition subtest were significantly easier or harder than their test placement indicated. The use of basal and ceiling rules had a pronounced effect on the means, variances, and reliabilities on the multiple choice math subtest, while the rules' effects on the reading recognition subtests were minor. Item order also affected scores on the math subtest. 相似文献

Developing local oral reading fluency cut scores for predicting high‐stakes test performance 下载免费PDF全文

This study evaluated the classification accuracy of a second grade oral reading fluency curriculum‐based measure (R‐CBM) in predicting third grade state test performance. It also compared the long‐term classification accuracy of local and publisher‐recommended R‐CBM cut scores. Participants were 266 students who were divided into a calibration sample (n = 170) and two cross‐validation samples (n = 46; n = 50), respectively. Using calibration sample data, local fall, winter, and spring R‐CBM cut scores for predicting students’ state test performance were developed using three methods: discriminant analysis (DA), logistic regression (LR), and receiver operating characteristic curve analysis (ROC). The classification accuracy of local and publisher‐recommended cut scores was evaluated across subsamples. Only DA and ROC produced cut scores that maintained adequate sensitivity (≥.70) across cohorts; however, LR and publisher‐recommended scores had higher levels of specificity and overall correct classification. Implications for developing local cut scores are discussed. 相似文献
