Assessing Perceived Credibility of Web Sites in a Terrorism Context: The PFLP, Tamil Tigers, Hamas, and Hezbollah
The purpose of the study was to contribute to the overall understanding of terrorist organizations' use of the Internet and to increase researchers' knowledge of Web site effectiveness. The methodological approach was evaluation of the perceived credibility of Web sites based on existing criteria derived from information users. The Web sites of four terrorist organizations were assessed: two secular nationalist groups, the People's Front for the Liberation of Palestine (PFLP) and Liberation Tigers of Tamil Elam (LTTE or Tamil Tigers); and two religious nationalist groups, Hamas and Hezbollah. The findings of this analysis showed differences in perceived credibility factors among terrorist organizations' Web sites and positive levels of perceived credibility for the Web sites. These findings indicate the potential for positive impressions of the organizations' Web sites by information users, which would help empower the organizations with the capacity to reach their objectives. By using Web sites, these groups can effectively increase their support base through disseminating information, improving recruiting, and attracting monetary contributions, and can establish themselves as legitimate components of society.

Assessing Play Interests in Toddlers.
Play is a significant part of childhood. Typically developing children exhibit a wide range of interests within their play behavior, but children with autism do not. The purpose of this study was to design and implement an assessment tool that will capture the constellation of behaviors indicating play interests in young children. The Early Play Interests Assessment (EPIA) includes categories of play behavior and their components behaviors. Additionally, measures of child affect were built into the EPIA. All behaviors were observed under various environmental conditions. The results show that the EPIA was useful in observing toddlers' play behavior within behavioral categories and components and in assessing the interactions among these measures of play interests. The results are discussed in relation to the importance of creating observational systems to quantify play interests in typical and atypical children and for establishing a link between the information gathered in assessment and the planning and implementation of autism interventions.

Assessing the Stimulus Control of Observers.
The science of behavior analysis relies heavily on direct observation. Human observers are typically used to measure behavior in applied settings. Although the use of human observers is beneficial in many regards, it also presents challenges. Of primary concern is the extent to which the data generated by observers actually corresponds to the behavioral events of interest, and the implications this may have in terms of replication. This study assessed the effects that labels, definitions, and examples and non-examples of two different modalities had on observer accuracy, consistency, and agreement. Results showed that current practices in observer training may require refinement to ensure high observer accuracy, consistency, and agreement. Suggestions for how to improve the desired stimulus control of observers are provided.

The Assimilation of Baroque Elements in Ferruccio Busoni's Compositions as Exemplified by the Fantasia nach Bach and the Toccata
Ferruccio Busoni (1866-1924) has a firmly established reputation as one of the giant pianists of his age, yet his compositions are largely neglected both in musicological circles and on the concert stage. A better understanding of his thought processes might lead to a greater appreciation of his art, and the acknowledgement of his reverence for the music of Bach is an important key to such an understanding. Busoni's Fantasia nach Bach and Toccata, although two decidedly dissimilar compositions in terms of purpose and conception, represent two manifestations of Busoni's respect for Bach, whether it be in the form of assimilating Bach's compositions into one of his own, or by creating an original work to the same mold as some of Bach's works.

An Attempt to Dissociate Effects of Response Requirements and Sample Duration in Conditional Discrimination Learning with Pigeons.
Attempts to control various aspects of response requirements and sample viewing durations of sample stimuli show that an increase in both facilitates acquisition of conditional discriminations. Despite these attempts, few empirical data exist that demonstrate the relative contributions of both response- and time-dependent schedules. In addition, viewing opportunities of sample stimuli are present outside of the researchers' control, allowing for 'unauthorized sample viewing.' This study employed a titrating delay matching-to-sample procedure to systematically control various aspects of response requirements and sample viewing durations to independently assess their relative contributions towards conditional discrimination performance. Four pigeons worked on a titrating delay matching-to-sample procedure in which the delay between sample offset and comparison onset continuously adjusted as a function of the accuracy of the pigeons' choices. Results show sample viewing durations contribute most toward conditional discrimination performance. The data show 'unauthorized sample viewing' improved acquisition of conditional discriminations and should be a consideration in design of future research.

Attitudes of International Music Students from East Asia toward U.S. Higher Education Institutions
Nine universities in the United States with the greatest number of international students and having an accredited music program through the National Association of Schools of Music (NASM) were selected. Survey research methodologies were used to identify the status of the international music students from East Asia in U.S. higher education institutions and to determine their attitudes toward their schools. Among East Asian international music students at US higher education institutions, the results indicated that the professor's reputation, scholarships, and the program's reputation were perceived as the most influential factors impacting the program choice; a good relationship with professors, good feedback from professors, and emotional stability were perceived as the most influential factors impacting academic success; and the professor's teaching, the professor's expertise, and the improvement of musical skills were perceived as the most influential factors impacting students' satisfaction level. The most problematic issues reported were the language barrier and the cultural differences between their host and own countries. In addition, many of the East international music students in this study noted financial difficulties.

Augeries, for Flute, Clarinet, Percussion and Tape: Aesthetic Discussion and Theoretical Analysis
Augeries is a multi-channel electro-acoustic composition for flute, clarinet, percussion, and tape. It is intended to be diffused through an 8-channnel playback system. Inspired by the first four lines of William Blake's Augeries of Innocence, Augeries captures the qualitative aspects of Blake's poetry by presenting the listener with an equally aperspectival aesthetic experience. The small-scale structure reflected on the large-scale form - the infusion of vastness and expansiveness into the fragile and minute. Augeries incorporates techniques of expansion and contraction, metonymic relationships, dilation and infolding of time, and structured improvisation to create an experience that is designed to explore the notion of musical time, and to bring to the listener the sense of time freedom. The critical analysis suggests that the increase in the notions of musical time, the aesthetics with which they conform, and the new time forms created, encapsulate communicative significance. This significance exists within a horizon of meaning. Semiotics illuminates an understanding of the structuring techniques used to render time as an area of artistic play. Understanding the aesthetics and mechanisms through which these techniques can be used constitutes a shared horizon of meaning. The concepts of cultural phenomenologist Jean Gebser, as explicated in The Ever-Present Origin, …

A Balancing Act: China’s Role in Climate Change
Climate change has reached the apex of the global agenda at a time when China faces significant development and energy security challenges. The political leadership and leading intellectuals are debating the direction of a new development pathway that provides both growth to meet development objectives, and dramatically reduces energy intensity and pollution. While the official position has not changed significantly, there are four key aspects that illustrate how climate change is conceived by the Chinese leadership. This signals that China may come to play a much more important role in global mitigation of climate change than was thought only a couple of years ago.

The Behavioral Changes that can be Realized when Leaders are Exposed to the Theories and Metaphors Found in Quantum Physics.
Many are beginning to see the promise that the quantum world has offered those who manage and lead organizations (Wheatley, 1992; Zohar, 1997). The Newtonian world is one in which all "things" are reduced to their smallest parts, separated, divided, and analyzed with predictability, with complete control being the ultimate goal. The quantum world is one of infinite possibilities, infinite fields of influence, and infinite relationships. The hallmark characteristics found in a manager who has been schooled in the quantum sciences are flexibility, responsiveness, synchronicity, serendipity, creativity, innovation, participation, and motivation. In a quantum organization there is the constant awareness of the whole system, but there is also diversity (wave or particle), which allows for self-organization that is based on the environment and its requirements. In the quantum world many paths lead from A to Z, and depending on the path chosen, numerous realities wait to unfold. It was the goal of this research to explore the changing of leader behaviors through exposure to the models and theories found in quantum physics. From a quantum perspective this behavior change is possible; the only question is the readiness, willingness, and ability of the leaders to allow their behaviors to be surfaced …

Benjamin Britten's Sonata in C for Cello and Piano, Op. 65: A Practical Guide for Performance
Benjamin Britten is a renowned and prolific English composer, well known for his operas and vocal works. He did, however, also compose five works especially for the cello as a solo instrument of which the Sonata in C for Cello and Piano Op. 65 was the first. He was inspired by one of his musical contemporaries, the remarkable Soviet cellist, Mstislav Rostropovich. Rostropovich was famous for his amazing artistry which propelled him to become one of the most prominent cellists in the world during his time. Thus Britten, who had previously only composed for cello as part of ensembles, created this sonata specifically thinking of Rostropovich and his outstanding skill as a cellist. The premiere of the sonata took place in July 1961 at the Aldeburgh Festival and it was a great success. However, despite Britten's reputation as an outstanding composer and the significance of the sonata, this sonata has been performed infrequently. Britten utilized many challenging techniques and adapted them innovatively in the composition, and perhaps performers may be reluctant to choose this work due to the complexity and challenge inherent in the composition itself. The purpose of this dissertation is to provide a practical guide for students and …

Bidirectional Effects Between Engaged Lifestyle and Cognition in Later Life: Exploring the Moderation Hypothesis for Personality Variables.
Longitudinal data (N = 263) was used to investigate the bidirectional relationship between engagement (engaged lifestyle activities) and cognition (crystallized & fluid intelligence). Extroversion and openness to experience were also tested as moderators of the relationship between engagement and cognition. Results showed that the relationship between engagement at Wave 1 and cognition at Wave 2 did not differ from the relationship between cognition at Wave 1 and engagement at Wave 2. Testing for moderation with regression indicated that neither extroversion nor openness was moderating the relationship between engagement and cognition in either direction. Structural equation models provided further summary evidence that the relationships among engagement at Wave 1, extroversion, openness, and cognition at Wave 2 were not strong. However, a strong limitation to these results was the measurement error associated with a new measure of engagement.
