The purpose of this paper is to provide a new theory of adjustable speed decoupled generation which has the potential to challenge existing coupled generation based on a classical synchronous generator operating with fixed speed.

The paper's approach is a theoretical consideration of the drawbacks of conventional fixed speed generation based on a synchronous generator and proposal of problem solutions by the introduction of a decoupled generation system with additional degree of freedom. Computer calculations are used as design and for preliminary verification. Tests in a real laboratory system equipped with modern components such as electrical machines and power electronic converters proved the theory.

Decoupled generation is realized in a very original way using new blocks, integration method and control. The developed system has been awarded more than six world patents. The system has additional degrees of freedom in speed and grid connection operation.

The research team has concentrated its research over many years and developed a generation system which has been awarded a great number of patents. A special axial flux, light and simple permanent magnet generator was developed and integrated to the prime mover. A three‐phase AC/AC power electronic converter and a DSP controller are integrated to a very small size and low weight. The invented topology provides a very reliable operation, high‐quality AC voltage in fully three‐phase non‐symmetrical load. There were also presentations on world conferences (EPE, PESC, EPE‐PEMC).

EVEN though, as all technical journals should be, we are completely apolitical, we cannot but notice that a General Election will be over by the time these words reach our readers. Who will win is, at this stage, anybody's guess—and many persons' hopes and fears.

This study aims to propose a model of publics' ethical activism, testing the role of emotional outrage in an extended framework of the previously established STOPS model. Thus, this study aims to investigate (1) how ethical perception of a social issue affects situational motivation that leads to participation in public activism, and (2) how emotional outrage plays a role in mediating between situational motivation and activism behaviors.

The study aims at investigating the mediating role of emotional outrage between situational motivation and activism behaviors, which have not been investigated thoroughly in public relations research. By conducting a national survey with 386 people (N = 386) living in Australia, the study's suggestive model was tested in the context of two ethical issues (e.g. climate change and anti-racism). This study found that people who perceive an ethical issue are likely to be motivated to participate in activism behaviors. Specifically, three situational perceptions (i.e. problem recognition, constraint recognition and involvement recognition) were found to be significant factors affecting situational motivation (SM) in problem solving. A high level of emotional outrage was found to play a mediating role between SM and consequential ethical activism behaviors. The more people feel outraged about an ethical issue, the more likely they will engage in punitive behavior. This study contributes to the theoretical development of public relations by illuminating how situational perceptions lead to emotional outrage that promotes behavioral intentions in an ethical context. This study also suggests that a practitioner should be sought to manage the levels of perceptual factors when setting up a communication plan in response to an ethical public crisis.

This study substantiates how three perceptual antecedents may conjointly affect situational motivation. Also, the findings in this study also contribute to theoretical development in predicting ethical activism intentions. Another contribution of this study is to demonstrate the mediating role of emotional outrage between situational motivation and ethical activism. The authors strived to explore individuals' perceptions and its impact on intention to boycott against ethical problematic social issues. It should be considered that this study used a hypothetical and manipulated situation where respondents are exposed to the visual stimuli that focus on the moral problems that those specific issues have raised.

First, as problem recognition plays a prime mover role in the overall problem-solving process in an ethical context, organizations should reduce individual's ethical problem recognition. When setting up a communication plan, an organization should showcase their positive role in addressing the ethical problems (e.g. to show Adani's commitment to indigenous people and efforts to protect the environment). The response strategy should be effective enough to create an “ethical dilemma,” which refers to a situation in which one has a difficult choice to make between two ethical options.

1. Introduction THE effect of torque is usually neglected in the Bernoulli‐Euler treatment of the flexure of thin rods. In practical cases the torque will rarely have any appreciable influence on static stability but from the dynamical aspect it may be the precursor of exponential instability in the absence of adequate damping forces. This phenomenon was suggested to me by Mr A. C. Hutchinson of Aliens, Bedford. Owing to torque there are cross deflexion coefficients which in particular cases are equal and opposite; and it is this negative reciprocity that gives rise to dynamic instability as we shall see. In the case, say, of a load on an overhung shaft it would appear that this instability is manifest at all speeds becoming more violent with the relative increase of torque. In practice it has frequently been found to be difficult if not impossible safely to run through particular ‘whirling’ speeds. In this connexion the problem of the stability of rotating shafts has reached a fresh peak of importance in consequence of the rapid development of the gas turbine as the prime mover in aircraft. The fundamental principles underlying the treatment of whirling phenomena are now well established and there is ample practical experience in support of the physical notion of shaft revolution propounded by Jeffcott in the Phil. Mag. for March 1919. Thus if a shaft is perfectly straight, completely balanced, and runs in bearings which are truly aligned; then, provided such masses as may be carried by the shaft have no appreciable moments of inertia, the normal ‘static’ flexural vibrations of the shaft will be independent of any imposed rotation, that is the path of any point on the neutral axis of the shaft will be uninfluenced by the rotation of the shaft section of which it is the centre. If the shaft is initially deflected by its weight, then the static vibrations will occur about the position of rest of the shaft and the imposed rotation will only apply to the cross‐sections of the shaft about their centres. If, however, the shaft is initially bent then each element may be considered as being ‘out of balance’ by the amount it is off the position it would occupy if the shaft were true and at rest. If we apply power to a bent shaft such as to maintain it in rotation with constant angular velocity then each element of shaft is regarded as being compelled to rotate with this constant angular velocity about the point on the effective elastic axis of the shaft, that is the axis of the deflected but corresponding unbent shaft. The unbalance will thus give rise to a forced vibration which will compel each element of the shaft to describe a circular path about its appropriate centre on the effective elastic axis; and this forced circular vibration will be independent of the static vibrations which are unforced and in consequence described as ‘free’. The radius of the path of any element in the forced circular vibration will depend inter alia on the speed of the imposed rotation, and the strain energy of the shaft so bent by flexure will be drawn or absorbed from the power which drives the shaft.

When the gas turbine took the aeronautical stronghold by storm it brought with it an opportunity, never wholly available to the piston engine designer, to apply thermodynamic theory more or less rigidly to the behaviour of the working fluid. For the first time in long years an internal combustion prime mover became amenable to mathematical analysis and, what is more, the predicted component performance could be realized on the test‐bed to a degree never possible with the reciprocating type. None the less the piston engine, with nearly 50 years of active application, has reached a remarkable standard of perfection on virtually ad hoc development alone in the hands of a multitude of experts whose efforts have undoubtedly made aviation history.

For a rotative winged aircraft having a variable pitch sustaining rotor capable of effecting direct take‐off and having a landing wheel with a wheel brake, a primary pilot's control organ for controlling the direct take‐off manoeuvre, said primary control organ being adjustable between a position providing a non‐lifting rotor blade pitch angle and initiation of rotation of the rotor in preparation for direct take‐off and a position providing a direct take‐off rotor blade pitch setting, mechanism interrelating the operation of said primary control organ and the wheel brake and providing for application of the wheel brake upon adjustment of the control organ to lower the blade pitch and initiate rotation of the rotor prior to take‐off and for release of the wheel brake upon adjustment of the primary control organ to effect direct take‐off, and separately controllable means for applying the wheel brake independently of the primary control organ.

The purpose of this paper is to analyze the reason for Chinese local officials' enthusiasm towards cultivating newly listed firms within their jurisdictions.

With new initial public offering (IPO) firms on the Chinese A‐share market over 1999‐2003 as samples, and using excessive employment as a measure of the carrying level of firms for political objectives of local governments, this study systematically investigates the change in policy burden for Chines firms before and after going public, the influence factors and their economic consequences.

The authors show that compared with before going public, the excessive employment of firms substantially increased upon going public, among which firms, state‐owned enterprises with better performances and private enterprises with closer links with government are heavier burdened with excessive employment. Furthermore, it was found that the increase in excessive employment upon going public can substantially aggravate the underperformance of IPO firms.

The findings in this study indicate that the new IPO firms do help local officials better realize their political objectives, and the local governments do actively use their rights of control or influence in pursuing their political appeals, and the political appeals of local officials brought loss of real economic efficiency to newly increased IPO firms.

This paper shows that the prime mover of Chinese local government in promoting securitization of local assets is effectively preserved by partial privatization, which is designed with the original intention of preserving governmental control over the economy.

The paper explains the Chinese local governments' enthusiasm for building capital provinces for reasons other than economic growth, i.e. political objectives; the paper provides evidence of how the political appeals of officials influence the capital market from the circumstance of government official selecting system, and builds a possible bridge in the relationship between government interventions and underperformance of the Chinese partially‐privatized firms.

The importance of engine testing lubricants is now fully appreciated by most large consumers of internal combustion engine oils, and by most oil companies. The value of chemical and physical tests are, and always will be, of great importance, but the need for tests that more specifically simulate operating conditions is very great in the light of modern developments in all types of prime movers, particularly internal combustion engines such as diesel and aero engines.

IT is always advisable to keep a record of lubricants issued from the stores. Storekeepers frequently tend to issue them too often on demand and without check. While there are dangers in stinting lubricants, the issuing of definite amounts at specified time intervals does keep consumption under control and prevents waste. A control system of this kind is particularly advantageous where prime movers are concerned because any gradual increase in consumption will often indicate the growing need for an overhaul, whilst a sudden increase, which would immediately be noticed, would provide evidence of rapidly developing serious trouble.
