The Effects Upon Specific Nonverbal Behaviors of Focusing Student Clinician\u27s Attention on These Behaviors Through Videotape Feedback and Instruction

The purpose of this study was to determine if a systematic approach to the study of nonverbal movements through the use of videotape playback and instruction provides a useful procedure for teaching nonverbal patterns and actions to student clinicians. Thirty female student clinicians who had completed between ten and 400 hours of clinical practice were divided into three groups and matched according to the number of practicum hours completed by each student. Group I received a one-hour training session which involved viewing of their videotapes accompanied by verbal instructions to attend to specific, defined, nonverbal behaviors. Group II received a one-hour training session in which the videotapes were not viewed, but the usage of the six nonverbal behaviors was defined and discussed. Group III received no training session, no videotape viewing, and no instruction. Each clinician was videotaped for ten minutes of her regularly scheduled therapy session. After the subject had participated in her particular training session and completed at least two, but not more than ten additional therapy hours, she was videotaped for another arbitrarily selected ten-minute period with the same client that participated in the first videotaping. These videotapes were then viewed by the experimenter and the six nonverbal behaviors which were selected for this study were counted. The mean number of occurrences of each of the six nonverbal behaviors was calculated for the three groups. Pretest and posttest data were analyzed using jt-tests and analysis of covariance. Group I displayed significant increases from pretest to posttest in the nonverbal behaviors which served as social reinforcers and produced \u27a significant decrease from pretest to posttest in the behavior of self-manipulation. Videotape playback viewing and instructions to attend to specific behaviors effected more change in the observed frequency of nonverbal behaviors than did instruction without videotape. There was a significant difference among the three groups on the nonverbal behaviors of eye contact and smile when controlling respectively on a pretest of the same behaviors. There was no significant difference among the three groups on the nonverbal behaviors of positive head nod, negative head nod, positive touch, and selfmanipulation when controlling respectively on a pretest of the same behaviors

Plankton Algae of the Upper Des Moines River, Iowa

Sedgewick-Rafter quantitative strip counts and proportional counts of Hyrax-mounted diatom slides were made on weekly grab samples taken at one station near Boone, and every other week at four other downstream stations during 1968 and January 1969. Eleven cyanophycean taxa, six green flagellate taxa, three taxa of other pigmented flagellates, and 42 taxa of other green algae were encountered. A total of 185 diatom taxa in 33 genera were identified, 75 of which are new to Des Moines River records. Biddulphia and Thalassiosira are diatom genera new to published records in Iowa

Honey Fungus: A Silent Killer

Armillaria root disease is found in many temperate and tropical forests throughout the world. It is responsible for on average 2-3 % of mortalities in infected forests. This root disease is caused by many species of fungus from the Armillaria genus. They are commonly referred to as Honey Fungus. This fungus spreads mainly through the interaction of tree roots. The Wind River Forest Dynamics Plot shows evidence of an infection by Armillaria. However the Extent of the infection has not been studied or mapped. Research Question : How much of the WFDP is infected and what are the effects of Armillaria on the plots mortality

Computationally Efficient Time-Recursive IAA-Based Blood Velocity Estimation

High-resolution spectral Doppler is an important and pow- erful non-invasive tool for estimation of velocities in blood vessels using medical ultrasound scanners. Such estimates are typically formed using an averaged periodogram technique, resulting in well-known limitations in the resulting spectral resolution. Recently, we have proposed tech- niques to instead form high-resolution data-adaptive estimates exploiting measurements along both depth and emission. The resulting estimates gives noticeably superior velocity estimates as compared to the standard technique, but suffers from a high computational complexity, making it interesting to formulate computationally efficient implementations of the estimators. In this work, by exploiting the rich structure of the iterative adaptive approach (IAA) based estimator, we examine how these estimates can be efficiently implemented in a time-recursive manner using both exact and approximate formulations of the method. The resulting algorithms are shown to reduce the necessary computational load with several orders of magnitude without noticeable loss of performance
