THE non‐metallic materials used in aircraft construction consist of a large number of different substances, to enter into any detailed discussions of which would occupy a volume of many pages. They are, however, conveniently classifiable into groups, and the reader will find, in what follows, some notes upon each group.

The Care and Maintenance of Aircraft. Second Edition. By Various Authors. (Airways Publications, Ltd., 3s. 6d.). The fact that a second edition of a technical work of this nature was called for within three months of the publication of the first is its own testimony to the value of the contents.

The publication of the fourth edition of Care and Maintenance of Aircraft now includes a new chapter, entitled “Aeroplane Timbers,” by Mr. A. W. Seeley, which constitutes another valuable addition to the instructive information to aeronautical engineers, etc., that has been incorporated in this publication since its inception.

The purpose of this paper is to provide evidence regarding the selection procedures for and characteristics of senior officials in supreme audit institutions (SIAs).

This study follows a quantitative approach using original data collected for presidential elections of SIAs in the 16 federal states in Germany. A fractional logit model is calculated to test different theoretical assumptions in relation to structural, political and individual factors.

The descriptive results confirm the findings of prior research that presidential candidates are elected with very high approval rates. The main determinants are the vote share of the ruling coalition and the executive experience of the presidential candidate.

This study focuses on 16 federal states in Germany, but an international comparative perspective covering subnational levels would further augment analysis through the variance of selection procedures and electoral outcomes.

Independence of auditors is a fundamental issue for the control of the executive, but it seems that there are inevitable trade-offs therein, such as between knowledge of the auditing objects or the politicization of the election process and the independence of the auditor.

This study provides novel empirical insights into the election and selection procedures for senior SIA officials at the subnational level, and shows that the executive exerts strong, but functionally reasonable, influence on candidate selection.

The purpose of this paper is to develop a novel integrated supplier selection approach incorporating decision maker’s risk attitude using the artificial neural network (ANN), analytic hierarchy process (AHP) and technique for order of preference by similarity to ideal solution (TOPSIS) methods.

In the proposed approach, the ANN model is used to classify decision maker’s risk attitude; the fuzzy AHP method is used to determine the relative weights of evaluation criteria; and the fuzzy TOPSIS method is used to evaluate ratings of suppliers. Finally, experiments are conducted to verify the feasibility and efficiency of the proposed integrated approach.

Experiments results show that the proposed integrated approach is effective and efficient to help decision makers to select suitable suppliers according to their risk attitudes.

The aim of this paper is to develop a novel integrated supplier selection approach incorporating decision maker’s risk attitude using the ANN, AHP and TOPSIS methods. The decision maker’s risk attitude toward procurement transaction is originally considered in supplier selection process.
