FOR landing on aerodromes, aircraft under‐carriages are now designed to give a certain safety factor on strength for specified conditions. These conditions have been determined after considerable investigations and represent the most severe landings that aircraft can reasonably be subjected to, and are defined in terms of the ground reaction applied to the wheels when the aircraft touches down at a specified arbitrary vertical velocity of descent in an airborne landing; i.e. the aircraft weight balanced by the aero‐dynamic lift on the wings. In a normal landing, of course, the aircraft is seldom 100 per cent airborne, but this assumption is a sufficiently accurate approximation. The vertical component of this ground reaction may be associated with various components of drag and side load, to cover for example the drag loads due to spinning up the wheels on surfaces with various coefficients of friction, ground ‘bumps’, drift, etc.

THE most severe ground loads to which an aircraft undercarriage is subjected when landing usually occur during the fraction of a second following the instant of touch‐down. Generally, less critical ground loads occur during the landing run, e.g. due to the application of wheel brakes, turning or swinging of the aircraft, the wheels striking obstacles, unevenness of runway, etc.

Assessment centres as a total system, involving theoretical, practical and technical aspects, are focused on. Recent research findings on assessment centres, their processes and practices, are discussed and the implications for practice are examined.

Suggests that the probability of transmission errors in the central neural system (CNS) is a major factor determining intelligence. That is, the smaller this probability, the larger is the intelligence of the subject. Explains the observation that Hendrickson’s AEP measures, which are supposed to measure this probability, are sometimes correlated positively and sometimes correlated negatively with IQ.

The purpose of this paper is to reconsider the impact of conservatism on political liberty and liberal democracy in contemporary society. It applies Weber's description of capitalism as the “most fateful” social force in modern society to analyzing conservatism in relation to political liberty and liberal democracy. The paper posits and finds that conservatism primarily (with secondary variations) negatively impacts political liberty and so modern liberal democracy. Alternatively, it argues and shows that conservatism almost invariably generates political repression and elimination or subversion of liberal democracy and society. It concludes that conservatism, especially in America, becomes from the “most fateful” to the “most fatal” social force on the account of its adverse impact on political liberty and democracy.

The paper aims to contribute to a better understanding of conservatism and its essentially destructive effects on political liberties and liberal democracy in contemporary society.

ONE of the chief elements of success in Public Library work is suitable accommodation for books and readers, and it is interesting to note that Mr. Andrew Carnegie has recognised this by granting his money, in most cases, for buildings only. This means that many new libraries will commence with the best conditions as regards accommodation, and so escape the disabilities attaching to some of the older libraries through being housed in adapted buildings. Adapted buildings are rarely a success from an administrative point of view, as I can testify from personal experience.

Describes the Spanish Civil War collection in the General Research Division of the New York Public Library. Lists some of the more than 2,500 entries on the Spanish Civil War and attempts an ideological balance between by providing a broad range of sources — Lists items in both English and Spanish.

The primary purpose is to investigate the relationship between narcissism and managers' overconfidence in listed companies' risk-taking.

In this study, two criteria of signature and reward are used to measure manager's narcissism; manager's overconfidence, using multiple regression models and finally to measure companies' risk-taking by using companies' monthly returns. Multiple regression is employed to test the model using a sample of 890 firm-year participation on the Tehran Stock Exchange from 2012 to 2017 with panel data and model with fixed effects.

The findings indicate that the CEO's narcissism and the board of directors positively and significantly affect corporate risk-taking. Also, managers' overconfidence has a positive and significant relationship with corporate risk-taking.

The results of this study identified other factors affecting companies' risk-taking. This study also contributed to the development of the literature on narcissism, overconfidence and corporate risk-taking.
