This article provides a review and conceptual comparison between self‐report and performance‐based measures of emotional intelligence. Analyses of reliability, psychometric properties, and various forms of validity lead to the conclusion that self‐report techniques measure a dispositional construct, that may have some predictive validity, but which is highly correlated with personality and independent of intelligence. Although seemingly more valid, performance‐based measures have certain limitations, especially when scored with reference to consensual norms, which leads to problems of skew and restriction of range. Scaling procedures may partially ameliorate these scoring weaknesses. Alternative approaches to scoring, such as expert judgement, also suffer problems since the nature of the requisite expertise is unclear. Use of experimental paradigms for studying individual differences in information‐processing may, however, inform expertise. Other difficulties for performance‐based measures include limited predictive and operational validity, restricting practical utility in organizational settings. Further research appears necessary before tests of E1 are suitable for making real‐life decisions about individuals.
Egyptian cotton straw powder was acid hydrolized in presence of coal tar phenols fraction (b.r. 170–185°C) to give the phenols‐furfural resin. Homopolyepoxy resin was prepared via condensation of epichlorohydrin with phenols‐furfural resin. Similarly copolyepoxy resin was also prepared from epichlorohyhdrin, phenols‐furfural resin and prepared bisphenol A based on coal tar phenols fraction. A study of curing these epoxy resins at 170–185°C with phthalic or maleic anhydride also curing at room temperature with amine was carried out. Also the effect of the addition of kaolin as a filler was investigated to find the optimum condition which allow the cured resin to act as wood adhesive. The obtained results were comparable with those of some commercial adhesives.

Argues that ethics and values are systemic realities and can be scientifically programmed in cybernetically oriented socio‐scientific systems. The case taken is of economic general equilibrium with possibilities of multiple equilibria. The treatment of ethics and values in this sense in economic theory makes them endogenous phenomena of socio‐economic reality. This substantive idea of ethics and values as endogenous phenomena in socio‐scientific systems is termed the principle of ethical endogeneity. Its social cybernetical possibilities are developed mathematically. While the mathematical treatment uses bilinear algebra for the formulation, greater importance may be seen in the scientific essence of the principle of ethical endogeneity applicable universally. This is particularly true of systems which need to be epistemologically unified.

Artificial automata replace, in part or in total, natural automata in systems, and properly disciplined models of natural automata become design models of artificial automata for replacement. In Part I, a summary of two sets of disciplines provided by a General Systems Theory is presented, and the importance of these disciplines to the modeling of three inherited abilities is indicated for a case study. A theorem is presented in the form of an algorithm to aid in the modeling of the ability to modify and extend knowledge structures. In Part II (appearing in the next issue), the proof of the theorem is given and the theorem is applied to the case study. Finally, the application of the disciplines of the General Systems Theory is indicated for a second casestudy of an industrial system of 10 interactive automata.
The most frequently used attribute sampling plan in MIL‐STD 105 D. In cases, however, when the quality level of incoming lots is generally sufficiently good, MIL‐STD 105 D often leads to unnecessarily high sampling cost. This can be avoided by using α‐optimal sampling plans. The authors outline the α‐optimal sampling scheme along with a simple procedure to determine α‐optimal sampling plans at workshop level. These plans depend on three parameters which have to be estimated from recorded data. In this article the effects of estimation errors in these parameters are investigated.
This paper aims to investigate the scuffing load‐carrying capacity of three gear oils: a standard mineral lubricant containing extreme pressure and anti‐wear additives (M0) and two biodegradable saturated esters containing low toxicity additives (E1 and E2).
Four‐ball wear tests were performed, according to standard ASTM D4172. Results from the wear scar diameter and from ferrographic analysis of the test oil samples are presented and related to the lubricant properties. The physical, chemical and biodegradability properties of the lubricants are presented and compared.FZG gear scuffing tests were performed, according to standard DIN 51535, in order to evaluate the scuffing load‐carrying capacity of the two oils. Two reference tests were performed, A20/16.6/90 and A10/16.6/90.
Test results include scuffing load stage, maximum oil bath temperature, pinion weight loss and surface roughness measurement of the teeth flanks.
The paper provides information on the scuffing load‐carrying capacity of three gear oils.

A manufacturing plant for the manufacture of diesel fuel injection equipment at Stonehouse, Gloucester, UK is being expanded at a cost of $60 million to cater for a new production using lean manufacture and without expanding the manufacturing area.
Your company may find itself traveling down several different paths at once to reach its goals. The secret of success lies in making sure the roads are compatible. At one time, selecting the right options was a matter of chance. Today, finding the winning combination is almost a science.

Three simple, single pass multi‐stage lot‐sizing heuristics are examined using simulation. The heuristics are based on using different cost policies in single stage lot‐sizing procedures when applied to a multi‐stage setting. The focus is on the echelon holding cost policy and its performance relative to using “full value” holding costs and McLaren's adjusted setup costs. It is shown that echelon holding costs can lead to an extremely poor overall cost performance. A simple measure that will detect situations for which the echelon holding cost policy is potentially not suitable is suggested and evaluated. Application of the proposed measure results in substantial cost improvements for the echelon holding cost policy; despite this, the policy was outperformed by the MLSA policy in most cases. More research is needed, however, before any conclusive evidence can be presented on the effectiveness of echelon holding costs in multi‐stage lot‐sizing.
