Counseling and clinical psychology doctoral students\u27 perceptions of their faculty\u27s ethical behavior
The purpose of this study was to examine the perceptions of psychology doctoral students with regard to their faculty\u27s ethical behavior. A review of the literature suggested that research on the perception of ethical behavior in academia has been narrowly focused on undergraduate students. Furthermore, many of the studies did not convey a comprehensive picture of the students\u27 perceptions of their faculty\u27s ethical behavior. A survey instrument was adapted from a survey used in a study of students\u27 view of their undergraduate professors\u27 actions (Keith-Spiegel, Tabachnick, & Allen, 1993). A randomized sample of 50 accredited counseling psychology doctoral programs and 50 accredited clinical psychology doctoral programs were chosen from the American Psychological Association\u27s Graduate Study in Psychology (2004). A complete list of non-accredited counseling psychology programs (5 total) and clinical psychology doctoral programs (13 total) were also acquired from the same source. Six surveys were sent to each program totaling 708 surveys. One hundred and twenty five usable surveys were returned after a follow-up notice was sent to the training directors of each program. Data analyses revealed statistically significant differences across counseling psychology and clinical psychology doctoral students in areas related to the perception and occurrence of a variety of behaviors including hugging a student, criticizing all theoretical approaches except those the professor personally prefers and insulting or ridiculing a student in the student\u27s presence. Although these differences were statistically significant, there are few practical differences between them. Anecdotal findings have also been categorized and discussed. Suggestions for future research are based on these findings
Interaction of photons with plasmas and liquid metals: photoabsorption and scattering
Formulas to describe the photoabsorption and the photon scattering by a
plasma or a liquid metal are derived in a unified manner with each other. It is
shown how the nuclear motion, the free-electron motion and the core-electron
behaviour in each ion in the system determine the structure of photoabsorption
and scattering in an electron-ion mixture. The absorption cross section in the
dipole approximation consists of three terms which represent the absorption
caused by the nuclear motion, the absorption owing to the free-electron motion
producing optical conductivity or inverse Bremsstrahlung, and the absorption
ascribed to the core-electron behaviour in each ion with the Doppler
correction. Also, the photon scattering formula provides an analysis method for
experiments observing the ion-ion dynamical structure factor (DSF), the
electron-electron DSF giving plasma oscillations, and the core-electron DSF
yielding the X-ray Raman (Compton) scattering with a clear definition of the
background scattering for each experiment, in a unified manner. A formula for
anomalous X-ray scattering is also derived for a liquid metal. At the same
time, Thomson scattering in plasma physics is discussed from this general point
of view.Comment: LaTeX file: 18 pages without figur
Design, synthesis, and subtype selectivity of 3,6-disubstituted b-carbolines at Bz/GABA(A)ergic receptors. SAR and studies directed toward agents for treatment of alcohol abuse
A series of 3,6-disubstituted ß-carbolines was synthesized and evaluated for their in vitro affinities at axß3V2 GABAA/benzodiazepine receptor subtypes by radioligand binding assays in search of a1 subtype selective ligands to treat alcohol abuse. Analogues of ß-carboline-3-carboxylate-t-butyl ester (ßCCt, 1) were synthesized via a CDI-mediated process and the related 6-substituted ß-carboline-3-carboxylates 6 including WYS8 (7) were synthesized via a Sonogashira or Stille coupling processes from 6-iodo-ßCCt (5). The bivalent ligands of ßCCt (32 and 33) were also designed and prepared via a palladium-catalyzed homocoupling process to expand the structure-activity relationships (SAR) to larger ligands
The Keck Low-Resolution Imaging Spectrometer
The Low Resolution Imaging Spectrometer (LRIS) for the Cassegrain focus of the Keck 10-m telescope on Mauna Kea is described. It has an imaging mode so it can also be used for taking direct images. The field of view in both spectrographic and imaging modes is 6 by 7.8 arcmin. It can be used with both conventional slits and custom-punched slit masks. The optical quality of the spectrograph is good enough to take full advantage of the excellent imaging properties of the telescope itself. The detector is a cooled back-illuminated Tektronics Inc. 2048 X 2048 CCD which gives a sampling rate of 4.685 pixels per arcsec. In the spectrographic mode the spectrograph has a maximum efficiency at the peak of the grating blaze of 32%-34% for the two lowest resolution gratings and 28% for the 1200 g mm^(-1) grating. This efficiency includes the detector but not the telescope or the atmosphere

Power tests of a string of magnets comprising a full cell of the Superconducting Super Collider
In this paper we describe the operation and testing of a string of magnets comprising a full cell of the Superconducting Super Collider (SSC). The full cell configuration composed of ten dipoles, two quadrupoles, and three spool pieces is the longest SSC magnet string ever tested. Although the tests of the full cell were undertaken after the SSC project was marked for termination, their completion was deemed necessary and useful to future efforts at other accelerator laboratories utilizing Superconducting magnets. The focus of this work is on the electrical and cryogenic performance of the string components and the quench protection system with an emphasis on solving some of the questions concerning electrical performance raised during the previous two experimental runs involving a half cell configuration
