The alternative proposed by Wilcox (1989) to the James second-order statistic for comparing population means when variances are heterogeneous can sometimes be invalid. The degree to which the procedure is invalid depends on differences in sample size, the expected values of the observations, and population variances. (SLD)

Describes and compares the results from two surveys of academic librarians in the State University of New York (SUNY) system that were conducted to determine librarians' satisfaction with faculty status. Evidence suggests that satisfaction correlates with institutional compliance with ACRL (Association of College and Research Libraries) standards.…

This paper reviews literature on evaluating allegations of child sexual abuse, to determine whether there are systematic and significant differences on psychological tests between sexually abused and nonabused children, and whether these differences are a direct result of sexual abuse or a result of other coexisting factors that might cause…

A new computerized mastery test is described that builds on the Lewis and Sheehan procedure (sequential testlets) (1990), but uses fuzzy set decision theory to determine stopping rules and the Rasch model to calibrate items and estimate abilities. Differences between fuzzy set and Bayesian methods are illustrated through an example. (SLD)

Seven different short forms of the Wechsler Adult Intelligence Scale, Revised (WAIS-R) were compared in a mixed clinical sample of 306 adults to evaluate short form predictions of the full scale IQ. The seven-test short form of C. Ward (1990) was the best predictor across ranges of intellectual functioning, supporting its use when time is limited.…

Studied children with word finding difficulties who were identified through a wider survey of educational provision for those with language and communication difficulties. (Author/VWL)

The relation between similarity and dissimilarity of context was analyzed for synonymous nouns. New semantic similarity and dissimilarity rating tests with an empirically determined series of linguistic anchors and conventional, arbitrarily anchored semantic similarity ratings were compared. Contextual similarity was elicited by a sorting test…

Looks at a sample conversation and examines layers of interpretation that different academic traditions have constructed to interpret it. Reviews studies that have compared the discourse of oral interaction in assessment with oral discourse in contexts outside the assessment. Discusses studies that related ways of speaking to cultural values of…

Ten cerebellar patients were compared to 10 control subjects on a verbal working memory task in which the phonological similarity of the words to be remembered and their modality of presentation were manipulated. Cerebellar patients demonstrated a reduction of the phonological similarity effect relative to controls. Further, this reduction did not…

This study examines young children's number sense in subjects from Finland (n =254), Hong Kong (n =246), and Singapore (n =130). Chinese, English and Finnish versions of the Early Numeracy Test (ENT; Van Luit et al., 1994) were used. Two highly correlated aspects of number sense were measured, one reflecting children's abilities to organize and…

Researchers have hypothesized that words that are highly related semantically are more likely to occur within the same intonational phrase (F. zzaq;, 1988; E. O. Selkirk, 1984). D. Watson and E. Gibson (2004) proposed that semantic closeness can be captured by using the argument/adjunct distinction, such that intonational boundaries are more…

With the current growth of the Internet, we expect significant changes in how and to what extent companies acquire business information. By comparing two studies on information seeking by small and medium-sized enterprises (SMEs) carried out in 1982 and 2003 respectively, and comparing the results with other studies, this paper indicates that the…

Many of the currently available statistical indexes to detect answer copying lack sufficient power at small [alpha] levels or when the amount of copying is relatively small. Furthermore, there is no one index that is uniformly best. Depending on the type or amount of copying, certain indexes are better than others. The purpose of this article was…

Powers, Burstein, Chodorow, Fowles, and Kukich (2002) suggested that automated essay scoring (AES) may benefit from the use of "general" scoring models designed to score essays irrespective of the prompt for which an essay was written. They reasoned that such models may enhance score credibility by signifying that an AES system measures the same…

We directly compared chimpanzee infants and human infants for categorical representations of three global-like categories (mammals, furniture and vehicles), using the familiarization-novelty preference technique. Neither species received any training during the experiments. We used the time that participants spent looking at the stimulus object…
