The Role of Fluency in the Emergence of the Derived Relations of Stimulus Equivalence

Description: Fluent component performances may be more readily available for recombination into more complex repertoires. This experiment considered the stimulus equivalence preparation as a laboratory analog for the co-adduction said to occur in generative instruction. Seven adults received minimum training on 18 conditional discriminations, components of 9 potential stimulus equivalence classes. Training was interrupted periodically with tests to determine whether fluency of original relations predicted e… more

Depression and Heart Rate Variability in Patients with Coronary Artery Disease

Description: Depression is an independent risk factor for morbidity and mortality in patients with coronary artery disease (CAD). Altered autonomic nervous system (ANS) activity, a common feature of depression, is also a risk factor for cardiac events in patients with CAD. Heart rate variability (HRV) reflects ANS activity, and reduced HRV predicts morbidity in cardiac populations. The purpose of this study was to determine whether differences in HRV exist between depressed and nondepressed patients with CA… more

Orchestral Accompaniment in the Vocal Works of Hector Berlioz

Description: Recent Berlioz studies tend to stress the significance of the French tradition for a balanced understanding of Berlioz's music. Such is necessary because the customary emphasis on purely musical structure inclines to stress the influence of German masters to the neglect of vocal and therefore rhetorical character of this tradition. The present study, through a fresh examination of Berlioz's vocal-orchestral scores, sets forth the various orchestrational patterns and the rationales that lay behi… more

The Continuous Wavelet Transform and the Wave Front Set

Description: In this paper I formulate an explicit wavelet transform that, applied to any distribution in S^1(R^2), yields a function on phase space whose high-frequency singularities coincide precisely with the wave front set of the distribution. This characterizes the wave front set of a distribution in terms of the singularities of its wavelet transform with respect to a suitably chosen basic wavelet.

Environmental Determinants and Choice of Project Evaluation Techniques in US and UK Firms

Description: The purpose of this dissertation is to develop a theory that helps explain the conditions under which firms select certain project evaluation techniques. This study uses contingency theory to analyze the impact of environmental uncertainty on the choice of project evaluation techniques. In addition to a direct measure of uncertainty, several dimensions of uncertainty are included in this study. These dimensions of uncertainty include control structure, method of financing, foreign assets, metho… more

Group Decision-Making in Computer-Supported Cooperative Work Environments

Description: Computer-Support Cooperative Work (CSCW) reflects the change in emphasis from using computers to solve problems to using computers to facilitate human interactions. Most studies, however, have focused on the use of the technology rather than on the human-human interaction (HHI) in these environments due to: the varied perspectives of the investigators; and the lack of a consistent variables. Although numerous studies exist on a variety of products, only limited research has been conducted with … more

Steady-state and Dynamic Probe Characteristics in a Low-density Plasma

Description: The problem with which this investigation is concerned is that of determining the steady-state and dynamic characteristics of the admittance of a metallic probe immersed in a laboratory plasma which has the low electron densities and low electron temperatures characteristic of the ionospheric plasma. The problem is separated into three related topics: the design and production of the laboratory plasma, the measurement of the steady-state properties of dc and very low frequency probe admittance,… more

Reciprocal Influences of Temperature and Copper on Fathead Minnows (Pimephales promelas)

Description: Acclimation temperature had a significant effect on the lethality of copper to fathead minnows in replicated 96-hour lethality tests. Lowest median lethal copper concentrations (LC50) were recorded at 12 and 22°C, with LC50s at 5 and 32°C at least 140 μg/1 higher. This research found LC50 copper concentrations in the 300 to 500 μg/1 range and a polynomial relationship between LC50s and acclimation temperature. Following a 24-hour exposure to three sublethal concentrations of copper, critical th… more
