Describes study that investigated whether assigning Library of Congress classification numbers to government documents, instead of the Superintendent of Documents classification numbers, would result in a wide scattering of the materials. Implications for the shelf arrangement of government documents are discussed, and further research is…

These three articles address issues in library cataloging that are affected by automation: (1) the impact of automation and bibliographic utilities on professional catalogers; (2) the effect of the LASS microcomputer software on the cost of authority work in cataloging at the University of Arizona; and (3) online subject heading and classification…

This case study analyzes five science courses of a United States virtual charter school. Online quizzes and exams are provided by the corporate partner, while local teachers have selected report topics, virtual labs and at-home labs for students to complete. These assessments were coded for their correlation to the cognitive levels of the revised…

With the resources provided by communication technologies, E-learning has been employed in multiple universities, as well as in wide range of training centers and schools. This book presents a structured collection of chapters, dealing with the subject and stressing the importance of E-learning. It shows the evolution of E-learning, with…

Virtual reality (VR) technology has demonstrated effectiveness in a variety of technical learning situations, yet little is known about its differential effects on learners with different levels of visual processing skill. This small-scale exploratory study tested VR through quasi-experimental methodology and a theoretical/conceptual framework…

This article focuses on how attitudes toward HLLs [heritage language learners] have changed, both with regard to program development and in learning and teaching. First, the ambiguity towards heritage language preservation is illustrated by examining historical aspects of heritage languages in the United States. Secondly, a closer look at two…

Two member onset consonant clusters with /s/ as the first member (#sC onsets) behave differently from other double onset consonant clusters in English. Phonological explanations of children's consonant cluster production have been posited to predict children's speech acquisition. The aim of this study was to consider the role of the Sonority…

We present an inference algorithm for perturbation models based on Poisson regression. The algorithm is designed to handle unclassified input with multiple errors described by independent mal-rules. This knowledge representation provides an intelligent tutoring system with local and global information about a student, such as error classification…

This paper is concerned with a specific case of L3 acquisition: the starting position for English vowel acquisition by infant German-Italian bilinguals will be investigated in light of prototype theory. The chosen example of triple language contact is characterised by consecutive bilingualism as the basis of L3 acquisition, where the learners' L2…

This article discusses the construction of the "emotional disturbance" (ED) category in the cases of four African American elementary students. These cases represent a sub-set of data from a three-year ethnographic study of the special education process in a large, culturally/linguistically diverse school district. Based on interviews,…

This paper aims to accomplish two things: first, to develop precise criteria to establish profiles for bilingual speech, following the typology of insertion, alternation and congruent lexicalisation developed in Muysken (2000); and second, to test these criteria on specific data sets. A first set involves Welsh-English bilingual data analysed by…

While five-month-old infants show orientation-specific sensitivity to changes in the motion and occlusion patterns of human point-light displays, it is not known whether infants are capable of binding a human representation to these displays. Furthermore, it has been suggested that infants do not encode the same physical properties for humans and…

Parkinson's disease (PD) patients and normal controls were tested in three category learning experiments to determine if previously observed rule-based category learning impairments in PD patients were due to deficits in selective attention or working memory. In Experiment 1, optimal categorization required participants to base their decision on a…

The statement matching paradigm was used to examine how 10- to 13-year-olds categorized adults when both ethnicity and gender varied across targets. Forty-seven children watched a PowerPoint presentation of a conversation involving two Black men, two Black women, two White men and two White women. Each slide displayed the speaker's picture, name…

This study investigates marketing three phenomena. First authors examine student's approaches to studying and learning, then they explore their conceptions of learning, and they finally delve into teacher's perceptions of student's learning. Authors recast the conceptions of learning literature in which they classify simplifiers, accountants,…
