A 3rd order theory of folding of viscous multilayers indicates that forms of folds are controlled by the behavior of layer contacts or interbeds, the relative stiffnesses of the multilayer and confining media, and the scale of the folding. A 2nd order analysis shows that asymmetry of folds is determined largely by the behavior of layer contacts and the sense of layer-parallel shear during folding.
Empathy was investigated as a multidimensional construct, including affective, cognitive, and communication processes. Observer subjects, who were administered the Interpersonal Reactivity Index (Davis, 1980), the State-Trait Anxiety Inventory (Spielberger, 1983), and the Social Skills Inventory (Riggio, 1989), rated the level of Expresser nervousness in anxious and comfortable videotapes. Those Observers reporting high affective empathy and high cognitive empathy also reported higher skill in nonverbal communication decoding and interpretation. However, highly empathic Observers did not report higher verbal communication decoding and interpretation skills. Contrary to previous research, those Observers low in affective empathy and high in trait anxiety showed significant increases in their state anxiety level after watching the anxious Expressers' videotape. The Observers, regardless of their reported level of cognitive empathy and trait anxiety, were able to differentiate anxious versus comfortable Expresser videotapes. The results are discussed in terms of their implications for empathy theory.
The present study examined acoustic, aerodynamic, and videostroboscopic measures of voice production following BOTOX injections in 4 patients with Adductor Spasmodic Dysphonia. Videostroboscopic measures showed a return to some normal aspects of vocal fold vibration 1 month post-injection. Several subjects exhibited suggested meaningful differences both one week and one month post-injection for acoustic and aerodynamic measures; however, results were highly variable and often did not bring the subjects' values into the normal range.
Compared to other drugs of abuse, studies of the effects of nicotine on intracranial self-stimulation (ICSS) are few in number. Since the effect of nicotine on reward is not well established, one goal of the present study was to clarify the characteristics of nicotine-induced changes in brain stimulation reward using a rigorously validated, rate-free and reward-selective procedure. Once established, the second goal was to assess the ability of specific dopamine (sulpiride), serotonin (MDL 26,508), and mixed dopamine/serotonin (MDL 28,133A) antagonists to modify nicotine's effects.
Alkylammonium ion exchange, x-ray powder diffraction (XRD), x-ray fluorescence spectroscopy (XRF), and high resolution transmission electron microscopy (HRTEM) have been used to study the chemistry and the physical properties of illite/smectite (I/S) clays from Paleozoic K-bentonites. The data have been used to evaluate current models of I/S interstratification and the mechanism of formation of illite during bentonite diagenesis.
In this dissertation, different space marching implementations of the Mollification method are introduced to numerically recover the temperature and heat flux histories on a bounded two-dimensional rectangular body when the initial sample data are collected on one side of the body. We combined the mollification method with a singular perturbation scheme to obtain a stable algorithm. A reliable set of parameter values is experimentally determined by numerical tests to guarantee the accuracy and stability of the algorithm.
