Studies of deformation properties of single-crystal material based on zirconium dioxide with application of photoelastic coatings

A technique of studying deformation properties on the basis of single crystals of partially stabilized zirconium dioxide using the method of photoelastic coatings is described. Linearity and elasticity of the material samples are studied under their compression up to destruction. The main mechanical characteristics of the material are presented.     

Differential perceptions of counselor behavior: Replication and extension.

Conducted 2 studies with 141 undergraduates in an attempt to replicate and extend the 1976 findings of M. B. LaCrosse and A. Barak (1976). In both studies the Counselor Rating Form was shown to be sensitive to perceived differences among and within counselors of moderate and minimal levels of training/experience. In both studies a significant positive relationship was noted between perceived counselor expertness, attractiveness, and trustworthiness and willingness to refer oneself to the observed counselor for a variety of counseling problems. The provision of a common baseline for S judgment (Study 2) resulted in expertness ratings more consistent with actual counselor training/experience than those of Study 1. The implications of this latter finding for methodological improvements in counseling analog studies are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Resonant cavity-enhanced mercury cadmium telluride detectors

The next-generation mercury cadmium telluride (HgCdTe) detectors will need to be able to spectrally resolve images to a degree far exceeding that currently available in two or even three color techniques. However, narrow, spectral pass bands will result in very low photon flux impinging on a detector. This paper investigates the use of resonant cavity-enhanced (RCE) detectors as a means of improving signal-to-noise performance of narrow spectral-width infrared (IR) detection systems.     

Managing large-scale programs: The managerial dilemma

Modern large-scale programs create new challenges for management. During the 1960s and 1970s, the whole field of macro-projects experienced a fundamental transformation that made many of the traditional approaches, methods and tools for administering large-scale programs no longer completely appropriate. Instead, successful implementation now requires the convergence of at least four elements: a positive societal cost/benefit calculation; a supportive bureaucratic-political context; appropriately broad managerial capabilities; and a favorable corporate strategic environment. The American synfuels experience exhibits a pattern of implementation failure that can take place when such a convergence does not exist. Modern macro-projects need a set of top-level managers who are comfortable with the traditional set of project management skills and with purely technological and economic matters, while also being at least equally as strong in the other more ambiguous domains of politics, bureaucracy, general management, and corporate strategy.
