Conceptual level and accuracy of person perception.

Conceptual systems theory asserts that abstract conceptual functioning must include a well-developed capacity to "act as if" and ability to assume the role of the other. This proposition was tested in two samples of adolescents with a person perception task that required subjects to give a target person's actual responses to Cattell's 16PF Test immediately after exposure to the target. Two videotaped targets were used. Conceptual level was found to influence accuracy as predicted in three of four analyses, and sex of subject as predicted in two of four, with the effects of intelligence controlled. Accuracy in the postdiction task, and four components of accuracy, were relatively stable across targets. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Deep traps in GaAs revealed at high resolution by simple fast photocapacitance methods

The characteristics of a new type of capacitance spectroscopy of deep traps in semiconductors are reviewed. A double radiation source technique is employed, the first source controlling the occupation of the traps and the characteristic time constant of the experiment, the second probing the spectral distribution of traps by selectively photoinducing emission to the conduction and valence bands. Time differentiation enhances the detectivity of the traps and minimizes drift problems. Typical spectra obtained with this quasi-equilibrium spectroscopic technique are described. The chromium trap in GaAs presents a distinctive feature with interesting properties which are discussed. Comparisons with thermal capacitance measurements are made, showing the complementary nature of the two methods. The use of the technique to detect out-diffusion of Cr from an insulating substrate into an epitaxial layer is described.

Quality at time of purchase of dried milk products commercially packaged in reduced oxygen atmosphere

Nonfat dry milk (NDM) and powdered whey beverages are available at the retail level, packaged in No. 10 cans in a reduced oxygen atmosphere to prolong shelf life. The objective of this research was to determine the sensory and nutritional quality of these dried milk products at the time of purchase. In the 10 brands tested, wide variation existed in headspace oxygen, can seam quality, sensory quality, and vitamin A (with 6 of 10 brands entirely lacking the vitamin). Manufacturers of dried milk products packaged in cans for long-term storage need to give careful attention to can seam quality, product labeling, and vitamin fortification. Consumers would be well advised to evaluate several brands of dried milk products prior to large quantity purchases.

把握建筑可持续发展设计的重心——充分考量建筑使用者在心理层面上对空间的需求

在建筑设计的可持续发展中,旧建筑的转型改造是其中一个有效手段。单纯的考虑采环境和自然资源的保护因素对旧建筑的转型设计是不全面的。对人(尤其是未来的可能建筑使用者)的心理层面有一个良好的把握,是今天做旧建筑改造原型设计过程中一个更加重要的环节。     

Level set X‐FEM non‐matching meshes: application to dynamic crack propagation in elastic–plastic media

This paper develops two aspects improving crack propagation modelling with the X‐FEM method. On the one hand, it explains how one can use at the same time a regular structured mesh for a precise and efficient level set update and an unstructured irregular one for the mechanical model. On the other hand, a new numerical scheme based on the X‐FEM method is proposed for dynamic elastic–plastic situations. The simulation results are compared with two experiments on PMMA for which crack speed and crack path are provided. Copyright © 2006 John Wiley & Sons, Ltd.
