Symmetry Breaking on a Rotating Hoop
The Rotating Hoop Launcher package shows the dynamics of a mass that is constrained to move on a rotating hoop. The rotating hoop model is an excellent mechanical model of first- and second-order phase transitions. Although the minimum of the potential energy curve corresponds to the bottom of the hoop at low rotation frequency, a spontaneous symmetry breaking (cusp catastrophe) occurs as the frequency is increased. This package presents the theory, a demonstration, and an Easy Java Simulation (

Hopkins Verbal Learning Test - Revised: Standardization Data of Percentage Retention and Comparison
The purpose of this study was to determine the utility of the Hopkins Verbal Learning Test-Revised (HVLT-R), as a brief neuropsychological screening measure of immediate and delayed verbal memory in a mild traumatic brain injury sample. From an archival database, neuropsychological test scores of 698 subjects with a recent mild-TBI were selected for the study. Age and education effects were analyzed with nonparametric measures. Correlations between the neuropsychological tasks were conducted.

University Faculty's Response to Student Loss by Death or Romantic Break-up
Coping with a significant loss is an issue that many college students will encounter while in an environment not conducive to the mourning process. As an institution that plays a large role in students academic and personal growth, universities need to be made aware of the unique challenges bereaved students face. This study was designed to assess university faculty response to and awareness of loss in college students. Types of loss assessed were the death of a family member, the death of a boy

Towards a Grammar of Leadership
Contemporary (empirical) leadership study (CLS) is beset with the inability to define its object efficiently. Consequently, CLS has generated hundreds of so-called leadership “definitions” with no end in sight, leaving the field in disarray. This situation of definitional indefiniteness is due to a lack of a fundamental (philosophical, non-empirical) theory of leadership that articulates a universal leadership reality that grounds and provides referential stability for empirical study.

SmatBook – a vision for the future e-book
This paper presents a vision for the future of the e-books as part of the growing collective intelligence. The vision entails further development of technologies that will facilitate the creation and use of a new generation of ‘smart’ books: e-books that are evolving, highly interactive, customisable, adaptable, intelligent, and furnished with a rich set of collaborative authoring and reading support services. The proposed set of tools will be integrated into an intelligent framework for colla

The Effects of Semantic and Thematic Clustering on Learning English Vocabulary by Saudi Students
The present study aimed to compare the effects of semantic and thematic clustering on learning English vocabulary by Saudi students. It investigated whether thematic grouping or the use of meaningful context facilitates vocabulary learning. It was also conducted to shed light on how the use of context might be combined with clustering in order to facilitate learning. The study consisted of two parts. In the first part, the quantitative stage, 160 participants studied four lists of English words

Structural Awareness for Collaborative Learning Environments
In this paper we propose a peer-to-peer support approach that we call structural awareness support. The structural awareness aims to support the communication that takes place in virtual learning communities. Its emphasis is on revealing the group structure to its participants in order to promote collaborative interactions. This support has been implemented on a forum type tool called Mailgroup. It has been tested twice in different contexts, obtaining initial feedback of its pertinence accordin

Parenting Education for Low-Income Parents of Preschoolers: What is the Most Effective Approach?
Parent education programs have been found to be effective interventions for lower-socioeconomic families. (Baydar, Reid, & Webster-Stratton, 2002). Although research has reliably reported that any parent training is better than no parent training (Helm & Kozloff, 1986), the effectiveness of group parent education programs which emphasize relational improvement is largely unknown.
