This study investigated the relative merits of using teacher judgment and the Slosson Full-Range Intelligence Test to estimate the math and reading achievement of students in a summer remedial-reading program. The subjects included children in grades kindergarten through six who were enrolled in the Auburn University Summer Clinic. Components analyses showed that the Slosson Full-Range Intelligence Test recovered substantially more variance from the distributions of the KeyMath-Revised and the Woodcock Reading Mastery Tests-Revised than did teacher judgments. Analysis of variance showed that significant differences between the means of the three tests resulted from the inclusion of students with learning disabilities. Implications of the results are discussed.  相似文献

Brain injury research in sport employs a variety of physical models equipped with accelerometers. These acceleration signals are commonly processed using filters. The purpose of this research was to determine the effect of applying filters with different cutoff frequencies to the acceleration signals used as input for finite element modeling of the brain. Signals were generated from reconstructions of concussion events from American football and ice hockey in the laboratory using a Hybrid III headform. The resulting acceleration signals were used as input for the University College Dublin Brain Trauma Model after being processed with filters. The results indicated that using a filter with a cutoff of 300 Hz or higher had little effect on the resulting strain measures. In some cases there was some effect of the filters on the peak linear (8–30g) and rotational measures (1000–4000 rad/s2), but little effect on the finite element strain result (approximately 2–6 %). The short duration and high magnitude accelerations, such as the puck impact, were most affected by the cutoff frequency of different filters.  相似文献

The role and continued relevance of state telecommunications regulators have been challenged by the development of competition, the introduction of new technologies, and the increasing dominance of federal authority. An important role that state utility commissions can play in the current telecommunications environment is to provide consumer education and information about consumer protection, competition, and universal service. Commissions can use their Web sites as effective tools in educating and informing consumers. This study analyzes the consumer-related telecommunications information included on the Web sites of the commissions in the 50 states and the District of Columbia to determine whether, and how well, state commissions are using their Web sites to educate and inform.  相似文献
