Social tagging enables librarians to partner with users to provide enhanced subject access. This paper quantifies and compares LC subject headings from each of 31 different subject divisions with user tags from Amazon.com and LibraryThing assigned to the same titles. The intersection and integration of these schemas is described and evaluated.…

The "Diagnostic and Statistical Manual of Mental Disorders" (5th ed.; "DSM-V") will likely place more emphasis on dimensional representation of mental disorders. However, it is often argued that categorical diagnoses are preferable for professional communication, clinical decision-making, or distinguishing between individuals with and without a…

The use of criterion group validation is hindered by the difficulty of classifying individuals on latent constructs. Latent class analysis (LCA) is a method that can be used for determining the validity of scales meant to assess latent constructs without such a priori classifications. The authors used this method to examine the ability of the L…

Insights into students' understandings of disciplinary concepts are fundamental to effective curriculum development. This paper argues that a rounded picture of students' understandings is required to support such development. It is argued that one element of this picture may be provided through the use of the Structure of Observed Learning…

For a test that consists of dichotomously scored items, several approaches have been reported in the literature for estimating classification consistency and accuracy indices based on a single administration of a test. Classification consistency and accuracy have not been studied much, however, for "complex" assessments--for example,…

Campuses that pursue the Carnegie Community Engagement Classification will in some form take full inventory of their engagement efforts in order to address the range of questions posed by the Carnegie Foundation. At an institution as large, diverse, and decentralized as North Carolina State University, this was no small undertaking. NC State's…

Generic sentences (e.g., "Snakes have holes in their teeth") convey that a property (e.g., having holes in one's teeth) is true of a category (e.g., snakes). We test the hypothesis that, in addition to this basic aspect of their meaning, generic sentences also imply that the information they express is more conceptually central than the…

The reported study follows the footsteps of Heider, and Simmel (1944) [Heider, F., & Simmel, M. (1944). An experimental study of apparent behavior. "American Journal of Psychology," 57, 243-249] and Michotte (1946/1963) [Michotte, A. (1963). "The perception of causality" (T.R. Miles & E. Miles, Trans.). London: Methuen (Original work published…

It is well established that faces, in contrast to objects, are categorized as fast or faster at the individual level (e.g., Bill Clinton) than at the basic-level (e.g., human face). This subordinate-shift from basic-level categorization has been considered an outcome of visual expertise with processing faces. However, in the present study we found…

Recent evidence suggests that the musical rhythm of a particular culture may parallel the speech rhythm of that culture's language (Patel, A. D., & Daniele, J. R. (2003). "An empirical comparison of rhythm in language and music." "Cognition, 87," B35-B45). The present experiments aimed to determine whether listeners actually perceive such rhythmic…

Ideal point discriminant analysis is a classification tool which uses highly intuitive multidimensional scaling procedures. However, in the last paper, Takane wrote about it. He concludes that the interpretation is rather intricate and calls that a weakness of the model. We summarize the conditions that provide an easy interpretation and show that…

The teacher-student relationship is viewed as integral to successful teaching and learning but, outside of a few exceptions, ethical boundary issues in this relationship have not been explored. The purpose of this study was to examine teachers' perspectives of their relationships with their students as well as how they described and negotiated…

As in any historical endeavor, periodization is an attempt to manage change, and present it coherently, by noting points where key breaks in framework occur. In world history, periodization has come to convey, particularly, shifts in the pattern of interactions and contacts among many, though not always all, major societies. In this article, the…

Consistency among the objectives, learning activities, and assessment exercises results in aligned courses, which give students direction and clarity and yield increased learning. However, instructors may not check for course alignment. This article describes a concrete way to determine course alignment by plotting the course components on a table…

A screening tool (in Chinese) for maladaptive internet use was developed in two stages. Thirty-five factors were first extracted from data obtained from 378 adolescents with a 179-item questionnaire. Nine higher-order factors were then obtained from 35 factors. A 26-item screen that measures both endogenous and exogenous factors was constructed on…
