A dissonance theory approach to defensive projection.

It was hypothesized that cognitive dissonance involving the self-concept leads to the use of projection to reduce the dissonance. Ss were given personality tests, and instead of true results received falisified data indicating favorable or unfavorable personality traits—thereby raising or lowering their self-esteem. In the presence of another S, Ss were shown pictures of men and were told this would be an indicator of their latent homosexuality; GSRs were supported to reflect their degree of anxiety. Ss were asked to estimate the reaction of the other S; Ss with high self-esteem tended to attribute a greater degree of responsiveness of the other S to the pictures. The relationship of psychoanalytic and dissonance theory is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

An argumentation-based method for managing complex issues in design of infrastructural systems

The many interacting and conflicting requirements of a wide range of stakeholders are the main sources of complexity in the infrastructure and utility systems. We propose a systemic methodology based on negotiation and argumentation to help in the resolution of complex issues and to facilitate options appraisal during design of such systems. A process-based approach is used to assemble and propagate the evidence on performance and reliability of the system and its components, providing a success measure for different scenarios or design alternatives. The reliability of information sources and experts opinions are dealt with through an extension of the mathematical theory of evidence. This framework helps not only in capturing the reasoning behind design decisions, but also enables the decision-makers to assess and compare the evidential support for each design option.     

An H-minimax approach to the design of robust control systems

A realistic feedback design problem is posed based on the minimization of a weighted combination of the sensitivity and complementary sensitivity matrices. A solution is obtained which makes use of the recently proposed methods for minimizing the sensitivity function alone.     

An evaluation of two approaches to discipline in industry.

A case involving clear-cut violation of a no-smoking rule, with a clearly defined penalty, was role-played by groups of industrial supervisors acting as foreman, union steward, and worker. After role-playing, 52% of the foremen altered their decisions and reached "adjusted" decisions (human relations approach); 35% persisted in following the rule (judicial approach); 13% failed to settle the matter in the time allowed. The human relations approach was more successful than the judicial in that the participants were better satisfied. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Toward the experimental control of dreaming: A review of the literature.

Reviews those scattered studies which attempt to control & empirically evaluate nocturnal dreaming. It may be possible to develop a functional experimental approach in which dreams become more immediate and observable aspects of behavior, rather than only memories. (96 ref.)

Approximate weight function technique using single-layer potential for a cracked circular disc

An efficient weight function technique using the indirect boundary integral method was presented for cracked circular discs. The crack opening displacement field was presented by a single layer whose kernel was a modified form of the fundamental solution in elastostatics. The application of a single-layer potential to the weight function method leads to a unique closed-form SIF (stress intensity factor) solution. The solution can be applied to a cracked circular discs with or without an internal hole or opening. For these crack geometries over a wide range of crack ratios, the SIF solution can be applied without any modification.

The calculation procedure of SIFs for the various cracked circular discs using only one analytical solution is very simple and straightforward. The information necessary in the analysis includes only two or three reference load cases. In most cases the SIF solution using two reference SIFs gives reasonably accurate results while the SIF solution with three reference load cases may be used to improve the solution accuracy of the crack configurations, with an internal opening or hole, compared with the solutions of the available literature.
