Continuity of care is the key.

Comments on D. W. Van Liere's (1978) response to the article by J. C. Matarazzo et al (see record 1978-32394-001) on psychologists' membership on the staff of university teaching hospitals, and argues that to provide continuity of care psychologists need to be full staff members of hospitals. The author suggests that psychologists should encourage hospitals to change, and should support the AAP in their suit against the Joint Commission on Accreditation of Hospitals.

Issues in the study of obedience: A reply to Baumrind.

A procedure devised for studying obedience in the context of a learning experiment involves the S being told to give increasingly severe electric shocks to another person; shock level is stepped up to the level marked "Danger: Severe Shock." "The purpose of the experiment is to see how far the naive S will proceed before he refuses to comply with the E." Baumrind has expressed concern for the welfare of Ss who served in the experiment and wondered whether adequate measures were taken to protect the participants and also questions the adequacy of the experimental design. The criticisms are answered. "By their statements and actions, S indicated that they had learned a good deal, and many felt gratified to have taken part in scientific research they considered to be of significance. The Ss themselves strongly endorse the experiment, and indicate satisfaction at having participated." (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychologist at city hall: A problem of identity.

Describes personal experiences as a representative of the Mayor of Boston. Psychological knowledge was secondary to the understanding of the political situation. The most important role change was to be concerned with the political welfare of the Mayor, rather than for the welfare of an individual or a community. Some psychological knowledge could be communicated usefully at policy meetings, but there was a limit to being helpful in social-political situations.

Correlates of the Psychotic Reaction Profile in an outpatient psychiatric sample.

Examined the correlates of the Psychotic Reaction Profile with a number of other psychological measures. Ratings on the Profile were obtained on 73 male psychiatric patients participating in a day treatment program in an outpatient clinic. Additional measures were obtained for this population on the WAIS, Holtzman Inkblot Test, Stroop Color-Word Test, and the Vineland Social Maturity scale. Findings indicate that Ss who rated high on thinking disorganization evidenced intellectual deficits, perceptual impairment, and a lower level of maturity. Ss who rated high on paranoid belligerence showed less perceptual distractability and evidenced a higher level of social maturity. The 2 scales also differed with respect to the criterion of discharge disposition. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Relations between age, mineral density and mechanical properties of human femoral compacta

Relations between mineralisation and mechanical properties have been investigated in human femoral compacta. Evidence of age-related changes in physical properties of bone, independent of mineral density, is provided by significant (P less than 0.05) partial correlation between ultimate tensile stress and age. However, 75 per cent of variance in ultimate tensile stress, and 85 per cent of variance in ultimate compressive stress could be accounted for by variation in mineral density.     

Respiratory mechanics in normal hamsters

Lung volumes and quasi-static deflation volume-pressure relationships were measured in male golden hamsters anesthetized with pentobarbital. Volume was measured with a pressure plethysmograph, and pleural pressure was estimated by the use of a water-filled esophageal catheter. Mean body weight +/- SE was 122.3 +/-3.0 g, mean lung weight was 0.74 +/- 0.2 g or about 0.6% of body weight. Mean lung volume at 25 cmH2O transpulmonary pressure (TLC25) was 7.2 +/- 0.14 ml, 9.78 +/- 0.17 ml/g lung weight or 5.92 +/- 0.06 ml/100 g body weight. Mean functional residual capacity was 2.4 +/- 0.06 ml or 33.3% of TLC25. Mean vital capacity was 5.2 +/- 0.13 ml. Mean quasi-static compliance of lung was 0.63 +/- 0.03 ml/cmH2O. Chord compliance of chest wall between lung volumes of 1 and 4 ml above RV was 3.39 +/- 0.53 ml/cmH2O. At FRC, the chest wall recoiled inward, so that pleural pressure was positive (1.4 +/- 0.13 cmH2O) and the lung was resisting further collapse. The slope of the lung's deflation volume-pressure curve changed at FRC, ERV was small (0.36 +/- 0.03 ml), and RV was determined by complete airway closure. Thus the mechanisms determining FRC are unusual and include an influence of airway closure.     

Reaction diffusion in the NiCrAl and CoCrAl systems

The oxidation life of a physically vapor-deposited overlay protective coating based on the Ni-Cr-Al or Co-Cr-Al (M-Cr-Al) systems is controlled by aluminum consumption resulting from alumina spalling, erosion, and interdiffusion with the substrate. The rates of these processes are determined by coating and substrate composition, service environment, and temperature. The purposes of this study were 1) to determine the effect of coating and substrate chemistry on the kinetics of interdiffusion and their relation to diffusion-zone constitution and 2) to develop a procedure for analyzing diffusion in multicomponent, multiphase systems. Semi-infinite diffusion couples with MCrAl sources representative of coatings and sinks representative of nickel-or cobalt-base gas turbine alloys were annealed at 1000, 1095, 1150, or 1205°C for as long as 500 h. The couples were examined by optical microscopy and layer growth measurements were made. Parabolic growth constants can be correlated with source aluminum content for a specific sink composition since changes in source aluminum content are more important than changes in chromium content. Sink composition is as important as source composition in determining β-recession kinetics in diffusion couples and life in finite coatings. Nickel-base alloys are more stable sources and stronger sinks than cobalt-base alloys. Total and diffusion activation energies were determined from layer growth constants. By introducing the concept of β source strength which can be determined from the appropriate phase diagrams, the Wagner solution for consumption of a second phase in a semiinfinite couple was successfully applied to the analysis of the MCrAl couples. This provided a method 1) for correlating β-recession rate constants with couple composition, 2) for determining reliable total and diffusional activation energies, and 3) for calculating interdiffusion coefficients.
