Similarity self-disclosure and return for a second interview.

Individually interviewed 50 male undergraduates for 20 min about procedures used in confronting decision-making situations. The interviewer disclosed experiences, attitudes, and feelings similar to those revealed by the students 0, 2, 4, 8, or 12 times during the interviews. An intermediate number of interviewer self-disclosures resulted in significantly more students returning for a 2nd interview than did few or many self-disclosures. Results suggest that the use of a moderate number of interviewer self-disclosures may be an effective means of increasing counselor attractiveness and client approach responses to the counselor.

Conditioned preferences in the rat with an unnatural need state: Morphine withdrawal.

Placed 30 morphine addicted and 15 nonaddicted female albino rats on a 21-day conditioning regimen which involved the daily alternation of access to either water, sucrose-octa-acetate (SOA), or no liquid for 1 hr. The addicted Ss received injections of morphine after either the SOA sessions or the no-liquid sessions. Nonaddicted Ss were injected with morphine after the SOA sessions. Following the last injection, Ss were given a 2-bottle preference test between SOA and water. Results show that the addicted Ss that received morphine-SOA pairings had an increased preference for SOA, whereas the nonaddicted Ss showed a decrease in SOA preference after the same conditioning treatments. Addicted Ss that received the morphine injections on the no-liquid days showed no change in SOA preference. (21 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Wavelet processing of images for target detection

This article has as its goal the development and test and evaluation of wavelet-based algorithms for automatically detecting unknown anomalies in two-dimensional images. The general idea behind the work is that the class of wavelet transforms induces a so-called multiresolution analysis (MRA) in image space whereby the image of interest is naturally decomposed into a sequence of images of varying resolution (from coarse to fine resolution) in a computationally efficient manner. The anomaly detection can then be performed sequentially beginning at a coarse scale (low resolution) and proceeding to finer scales as needed. The wavelet representation thus effectively allows the user to zoom in on particular areas of interest and thus detect image anomalies in a very efficient manner. The article includes results from computer simulations testing the proposed approach against a standard energy-detection algorithm for the unknown anomalies embedded in additive Gaussian white noise. © 1996 John Wiley & Sons, Inc.     

Continuous Saccharification of Corn Starch in a Membrane Reactor. Part I: Conversion,Capacity and Productivity

Effects of enzyme concentration, substrate concentration and residence time on substrate conversion, reactor capacity and productivity were evaluated. As enzyme concentration increased from 1 to 6 g/L, substrate conversion also increased. Substrate conversion was essentially unchanged at enzyme concentrations greater than 6 g/L. Reactor capacity was significantly affected by both substrate and enzyme concentration. As residence time increased, substrate conversion increased 15–22%. Productivities of the continuous reactor were 10 to 20 times greater than those obtained in a batch reactor. The continuous membrane reactor was capable of producing a highly pure glucose syrup at low residence times. Due to the high levels of substrate conversion, minimal operational problems were experienced.
