Purpose: To evaluate the discriminant accuracy of a grammatical measure for the identification of language impairment (LI) in Latino English-speaking children. Specifically, the study examined the diagnostic accuracy of the Test of English Morphosyntax (E-MST; Pena, Gutierrez-Clellen, Iglesias, Goldstein, & Bedore (n.d.) to determine (a)…

This article investigates several methods of identifying individual guessers from their response data. Both the posterior probability method and the likelihood ratio method are based on the two-state mixture modeling approach to response times. The accuracy method is based on response accuracy data. Results from the simulation study showed that…

This case study explored one teacher's understanding of knowledge using an adaptation of the "Approach to Knowledge Scheme". By using this Scheme it was possible to see how this teacher's views impacts what knowledge Mrs. Smith (a pseudonym is used) found valuable and how she transmits these values to students and in so doing, provided an…

Social environmental assessments can play a critical role in prevention planning in schools. The purpose of this study was to describe the importance of conducting social environmental assessments, demonstrate that complex social environmental data can be simplified into a useful and valid typology, and illustrate how the typology can guide…

This article is the third and final in a series prepared originally for AACRAO's Fifteenth Annual Strategic Enrollment Management Conference (SEM XV). Through this series, David Kalsbeek introduces a four-fold typology for differentiating institutional approaches to SEM. In this final reflection, he suggests that grounding this typology in Jungian…

The measurement of Hispanics in the 2000 U.S. Census significantly skews the racial identification of the Hispanic population in America. The literature on racial and ethnic identification, however, lacks serious engagement with the social psychology of self-identification. We draw on social identity theory to demonstrate how the process of…

One hundred 18-month-olds were tested using sequential touching and following 4 different priming contexts using sets of toys that could be simultaneously categorized at either the basic or global level. An exact expression of the expected mean sequence length for arbitrary categories was derived as a function of the number of touches made, and a…

Stigma can greatly exacerbate the experience of mental illness. Diagnostic classification frequently used by clinical social workers may intensify this stigma by enhancing the public's sense of "groupness" and "differentness" when perceiving people with mental illness. The homogeneity assumed by stereotypes may lead mental health professionals and…

This report describes an experimental system for remote direct access to files of computer-stored information which has been indexed by the Universal Decimal Classification (UDC). The data base for the experiment consisted of references from a single issue of Nuclear Science Abstracts. The Special Subject Edition of UDC for Nuclear Science and…

This paper discusses visual communication theory. After an examination of the literature, this study built a more extensive bibliography of visual communication in general--theory, research, teaching--as well as a taxonomy that was better grounded. A 95-page bibliography was developed for works from a number of scholarly journals dealing with…

This report is the fifth in a series that constitutes a comprehensive evaluation of the public library statistics program carried out annually by the Federal State Cooperative System for Public Library Data (FSCS). The evaluation aims to revise and promote the FSCS classification structure that divides library organizations into municipal, school…

Natural systems are self-organizing and stratify according to the angular articulation of their movements. In particular, movement is relative to the levels that define its behavior space. As natural phenomenon, text production is self-referential, In generating information, the intention of the producer of a text becomes specified. Specifying of…

When analyzing open-ended or categorical questions, many times responses are cross-classified by other categorical variables. The resulting contingency tables are then analyzed using the chi square test of independence. This procedure leads to multiple significance tests and provides no method to assess higher order interactions. Loglinear…

Methodological issues of using a class of neural networks called Mixture Density Networks (MDN) for discriminant analysis are discussed. MDN models have the advantage of having a rigorous probabilistic interpretation, and they have proven to be a viable alternative as a classification procedure in discrete domains. Both classification and…

The purpose of this "primer" for the general public is to describe the general characteristics of wetlands and how wetland alteration adversely affects the well-being of humans. Particular emphasis is placed on wetlands in New York State and the northeast. Topics discussed include wetland values, destruction of wetlands, the costs of…
