Discusses a revision of existing respiratory physiology simulations to promote active learning experiences for individual students. Computer graphics were added to aid student's conceptualization of the physiological system. Specific examples are provided, including those dealing with alveolar gas equations and effects of anatomic shunt flow on…

A study investigated effects of acute exercise: (1) on overall body relaxation, as measured by the reaction of the frontalis muscle; and (2) as an aid to biofeedback-induced relaxation. Exercise did not promote generalized relaxation in this study, nor did it affect the learning of biofeedback techniques. (Author/PP)

Reviews literature about symptoms and causes of burnout. Most offer little theoretical foundation but assume an energy scarcity model. Offers an alternative model based on the assumption that energy is highly expendable. Marks (1977) argues that the critical variable is commitment, enhanced by loyalty, enjoyment and rewards. (Author/JAC)

Using ascorbic acid enzyme assays in conjunction with chronoamperometric measurements, reliable values for the principal electroactive components in the rat caudate extracellular fluid were established. Techniques used in the study are discussed. (JN)

A college level plasmolysis experiment, demonstrating principles of cell/water relations, has been modified to demonstrate the objective collection of data. Background information, laboratory procedures, results, and instructional strategies are provided. (Author/JN)

Psychological and physiological stress indices were taken from collegiate swimmers of both sexes. Later a scale of self-reported masculinity and femininity was administered. Males had higher systolic blood pressure but lower self-reported anxiety and hostility with the stress of competition. Differences in relative masculinity/femininity allow…

Measured oxygen consumption, subjects' respiration rate, heart rate, and blood pressure before and after learned Transcendental Meditation (TM) or Jacobson's Progressive Relaxation. Found TM group displayed more significant decreases during meditation and activity, explained primarily in terms of greater amount of time the TM group spent on their…

Directed at the candidate seeking a permanent position in physiology. Reviews qualifications candidate must have and lists sources of information about the present job market and agencies through which the candidate's availability may be made known. (Author/JN)

Describes a model which gives realistic predictions of pulsatile pressure, flow, and volume events in the cardiovascular system. Includes computer oriented laboratory exercises for veterinary and graduate students; equations of the dynamic and algebraic models; and a flow chart for the cardiovascular teaching program. (JN)

Investigated the extent to which response length influences Holtzman Inkblot Technique (HIT) scores in (N=102) elderly. Results suggest that response length has a pervasive effect on HIT scores and bears out the productivity of effects found in previous research with younger age cohorts. (JAC)

Reviews employment opportunities of Ph.D. physiologists in clinical settings, the positive and negative dimensions of the functional role of a clinical researcher, and the need for collaboration between basic scientists and physician-researchers. (DC)

Recent trends in physical education programs show a diverse spectrum of clients and an increasing amount of health-related litigation. These developments call for increased emphasis on exercise prescription. The sit-up is used in an example of a step-by-step guide to prescriptive technique. (JN)

Physical education should be considered a basic component of education since it contributes to the total development of the individual. However, physical education objectives have not been reached, in spite of research supporting the goals and a large percentage of students participating in physical education programs. (JN)

Presented is one of a series of articles designed to help science teachers keep current on ideas in specific areas in biology. Contained is information on how plants use light for growth, seed germination, and flowering. (PB)

Describes biofeedback as the monitoring of a physiological function and the awareness of that by the person. Has been used in counseling as a relaxation aid. Other potential uses include improving clients' internal locus of control, reducing depression, diagnosing, and monitoring progress. Includes cautions and recommendations for counselor…
