Interpreting the Good Life: Growth Memories in the Lives of Mature, Happy People.

In 2 studies, the authors examined autobiographical memories for the presence of 2 growth orientations that were expected to correspond differentially to maturity and well-being, which are considered to be key facets of "the good life" by L. A. King (2001). Mature participants emphasized integrative memories (conceptual integration and learning), whereas happy participants emphasized intrinsic memories (humanistic concerns). Both kinds of growth memories correlated more strongly with eudaimonic than with hedonic measures of well-being. Growth memories were largely independent of Big Five traits in relation to maturity and well-being. Finally, older participants were more likely than younger participants to have greater maturity (marginally) and well-being, but this was in part explained by older participants' greater tendency to have growth memories. The discussion considers the role of growth memories in the intentional cultivation of the good life. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

砂岩型铀矿弱信息提取及综合评价方法技术研究

Phase and microstructure of tungsten coating on C/C composite prepared by double-glow plasma

W-coated C/C composite is the most interesting as the ITER plasma facing components. In this paper, a dense W-modified layer was prepared on the C/C composite substrate by double-glow plasma method using pure W as target. Argon was input into the chamber as the plasma and the reactive gas. Phase and microstructure of as-prepared coating were examined by the X-ray diffraction and scanning electron microscopy, respectively. The results indicated that the dense W-modified layer could be successfully coated on the surface of the C/C composite substrate by double-glow plasma method. The W-modified layer was made of many columnar grains extending perpendicularly outward from the C/C composite substrate. There was a transition layer honeycomb-like between W coating and the C/C composite substrate. The adhesive force of the W coating and C/C substrate was about 21 N.
