The anisotropic elastic response of body centered cubic (b.c.c.) and face centered cubic (f.c.c.) crystals is reviewed within the framework of general elasticity and particular model dependent relations. It is found that important trends in the observed behavior of specific groups of crystals can be reproduced by models that include only structural contributions to crystal binding. In fact, a very simple model, consisting of only nearest and next nearest neighbor interactions, reproduces the salient behavior, including the algebraic signs of Poisson's ratio and the orderings of the shear moduli, Young's moduli, and Poisson's ratios associated with major crystallographic symmetries. The analysis provides insight into the differences between the b.c.c. transition metals and the b.c.c. alkali metals.  相似文献

The earliest reference to the immediacy of reinforcement in E. L. Thorndike's writings is found in Animal Intelligence (1911), not in Volume 1 of Educational Psychology as previously stated in an earlier article by L. T. Benjamin and R. Perloff (1982).

Discusses why E. G. Boring left the laboratory to become the foremost historian of experimental psychology. The position of psychology in general and at Harvard in particular in the mid-1920s is examined, and it is concluded that Boring turned to history because he could not accept the current phenomenological or behavioristic approaches. The Zeitgeist had rendered Titchenerian structuralism obsolete so it was natural for Boring to devote himself to the history of the great sensory tradition. His inclusion of James and Freud among the "very great" psychologists showed his growth in appreciation of men outside the structuralist school. Boring's career exemplified the positive and negative interactions of eponyms with the Zeitgeist which he maintained was an essential factor in the progress of science. (19 ref.)

Two multivariate studies examined the applicability of the theory of planned behavior in gauging students' attitudes toward mathematics, as well as the predictive power of mathematics attitudes in explaining students' grades in mathematics. Middle-school students from the United States (N = 382) and Belarus (N = 339) participated. Confirmatory factor analysis supported the viability of the theory for both samples. The analyses revealed that between 25% and 32% of the variance in mathematics grades could be explained by the theory of planned behavior components. In fact, 17% of the variation in test grades could be explained by the theory of planned behavior over and above the effects of mathematics ability test scores. Mean score differences between countries were small (ds = .15 to .27), with Belarusian students scoring more highly on attitudes and control but less highly on subjective norms and intentions. The article concludes with discussion of potential interventions and the need to expand results to different age groups and achievement domains, as well as the need for longitudinal and cross-cultural research.

The US South, and western regions of the US initially settled by Southerners, are more violent than the rest of the country. Homicide rates for White Southern males are substantially higher than those for White Northern males, especially in rural areas. But only for argument-related homicides are Southern rates higher. Southerners do not endorse violence more than do Northerners when survey questions are expressed in general terms, but they are more inclined to endorse violence for protection and in response to insults. Southern Ss responded with more apparent anger to insults than did Northerners and were more likely to propose violent solutions to conflicts presented in scenarios after being insulted. The social matrix that produced this pattern may be the culture of honor characteristic of particular economic circumstances, including the herding society of the early South. Consistent with this possibility, the herding regions of the South are still the most violent. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献
