Background: The role of nurses as patient advocates is one which is well recognised, supported and the subject of a broad body of literature. One of the key impediments to the role of the nurse as patient advocate is the lack of support and legislative frameworks. Within a broad range of activities constituting advocacy, whistleblowing is currently the subject of much discussion in the light of the Mid Staffordshire inquiry in the United Kingdom and other instances of patient mistreatment. As (...) a result steps to amend existing whistleblowing legislation where it exists or introduce it where it does not are underway. Objective: This paper traces the development of legislation for advocacy. Conclusion: The authors argue that while any legislation supporting advocacy is welcome, legislation on its own will not encourage or enable nurses to whistleblow. (shrink)

What ecological advantages do animals gain by being able to detect, extract and exploit wavelength information? What are the advantages of representing that information as hue qualities? The benefits of adding chromatic to achromatic vision, marginal in object detection, become apparent in object recognition and receiving biological signals. It is argued that this improved performance is a direct consequence of the fact that many animals' visual systems reduce wavelength information to combinations of four basic hues. This engenders a simple categorical (...) scheme that permits a rich amount of sensory information to be rapidly and efficiently employed by cognitive machinery of limited capacity. (shrink)

This text demonstrates that symbolic representation and related problem-solving methods offer significant opportunities to clarify and articulate concepts of design.

Yellow sun in a blue sky. Green leaves caressed by the wind. Open the shutters of the eye, that window of the soul, and all such things are revealed. Nothing is more apparent than that things have colors, and that we have immediate perceptual access to those colors.

At 8 a.m. I get in my car and set off for work. At 7:59 a.m., before I started it, my car was at rest; at 8:01 a.m. it is in motion. When a thing is not in motion, it is at rest, and when it is not at rest, it is in motion. But what was the state of the car at 8:00 a.m., as I was starting it? It would be inaccurate to say that it was in motion (...) but it would be inaccurate, also, to say that it was at rest: it was “just starting.” But, if whenever a thing is not in motion it is at rest, the state of “just starting”—or, of course, the comparable state of “just stopping”—must be either a state of motion or a state of rest. Which? (shrink)

This detailed and sympathetic, but not uncritical, study of On Liberty' argues for the general consistency and coherence of Mill's defence of individual liberty, but maintains that there are significant non-utilitarian elements in his arguments.

In the essay On Liberty , Mill put forward his famous principle that society may only interfere with those actions of an individual which concern others and not with actions which merely concern himself. The validity of this principle depends on there being a distinction between self-regarding and other-regarding actions. But the concept of self-regarding actions has been severely criticised on the ground that all actions affect others in some way and are therefore other-regarding. The notion of self-regarding actions appears (...) to be completely discredited. Very recently, however, there has been some dissatisfaction with the traditional debunking of Mill on this score. Two serious and important attempts to reinterpret the principle were made by Mr J. C. Rees in an article entitled ‘A Re-Reading of Mill on Liberty’, and by Mr Alan Ryan in two brief but extremely useful contributions. My aim is to discuss these reinterpretations of Mill, and on the basis of this, build up what I think is the correct account of Mill's notion of self-regarding actions. (shrink)

One dark and rainy night, Yuso sexually assaults and tortures Zelan. In escaping from the scene of his crime, he falls heavily and becomes an impotent paraplegic. Instead of treating his fate as divine retribution for his wicked acts, Yuso sees it as sheer bad luck. He shows no remorse for what he has done, and vainly hopes that he will recover his powers, which he now treats as involuntarily hoarded resources to be used on less rainy days. In the (...) presence of others, he pretends that he has turned over a new leaf. He asks for religious and educational books, hoping to make up for his poor education and deprived social background. But he immediately discards them when he is alone in favor of the pornographic magazines which he has bribed a nurse to smuggle in for him. His deception and various obscene acts committed in the hospital are exposed; by the time he comes up for trial, everyone knows that he is still a lustful, sadistic, and unrepentant man. Most retributivists have a sufficient justification for punishing Yuso independently of the social consequences of his punishment. Two features of the case might cause some difficulties. First, Yuso has already experienced considerable suffering and deprivation both before and after his crime, and retributivists might disagree about the relevance of the suffering to his punishment. Secondly, Yuso is unrepentant, and it is unlikely that punishment will change him. This might, as we shall see, create a problem for those who think that the justifying aim of punishment is the moral reform of the offender. (shrink)
