This paper characterizes quasi-pure projective (q.p.p.) and quasi-pure injective (q.p.i.) p-groups, and hence characterizes all such (abelian) torsion groups. A p-group is q.p.i. if and only if it is the direct sum of a divisible group and a torsion complete group. A nonreduced p-group is q.p.p. if and only if it is the direct sum of a divisible group and a bounded group; a reduced p-group is q.p.p. if and only if it is a direct sum of cyclic groups. © 1977 American Mathematical Society.

The findings in this study that self reported acceptance of self and others and interpersonal skills increased following the Workshop must themselves be regarded within the limitations of a small sample, an analysis of only one leader's group participants, measurements by ratings, and a quasi experimental design. Nevertheless, human relations training appears to be a valuable component to program more systematically into teacher education. Work in developing specific training goals and procedures relevant to personal growth as related to competence in the classroom is the next step. The fact that such a short training program could affect the way student teachers feel about themselves should encourage further research and experimentation.

Locus of control is a personality variable that manifests itself through an individual’s perception of the reinforcement he receives. This belief system is based on a continuum ranging from the perception that rewards are completely contingent upon one’s behavior to the belief that only luck, chance, or fate control one’s life. This construct has received considerable attention within the realm of psychology, but is conspicuous by its absence in sport and physical education literature. The purpose of this study was to compare the locus of control of highly skilled Dutch (N = 35) and American (N = 44) women softball players. The Rotter internal-external locus of control scale was utilized to determine internal-external orientations of the subjects. Data were analyzed by using ANOVA and product moment correlations. Statistically significant (.01 level) differences in locus of control were found. American women softball players were significantly more internally oriented than were their Dutch counterparts. © 1977 Taylor 8 Francis Group, LLC.

In attempting to derive the minimal component of the Poggendorff figure which would still produce an illusion, responses to three types of transversal were measured. One was the customary solid line type; a second type presented the two segments sequentially, alternating between them; and the third consisted of a moving dot which traveled the transversal path. Each transversal was shown with and without verticals, for a total of six conditions. Ten subjects in each condition adjusted the luminous transversal until the segments appeared to be collinear. Figures with verticals present showed a greater magnitude of illusion than those without, and discrepancies for moving dot transversals were greater than those for comparable solid line figures. Since alternating transversals were not significantly larger than solid line figures, it was concluded that the magnitude of the moving dot effect could not be attributed to temporal sequence. An eyemovement hypothesis was suggested instead. © 1977 Psychonomic Society, Inc.

The localization ability of 10 normally hearing adults was determined under varying microphone separations and varying sound source azimuths. The stimuli (white noise bursts) were prerecorded, after being transduced through 'body' hearing aids and then played to the subjects over headphones. Results indicated that there was an improvement in localization ability for all azimuth conditions when the microphones were spaced wider than 12.7 cm apart (15.2-30.5 cm). The smaller the separations (5.5-12.7 cm), the poorer the localization. Localization was always poorer at 30° azimuth (the smallest used) than at any of the other azimuths (0° 30° 60° 90° right and left), regardless of microphone spacing. Implications are made about the relation of these findings to the use of binaural body aids on infants and young children. © 1977 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
