Towards an Understanding of the Notion of the Spiritual in Education

The notion of the 'spiritual' is notoriously difficult to define. While it has been a legal requirement for schools to develop the spiritual aspect of children's lives Since 1944, it is only recently that any serious attempt has been made to define what is meant by the term.

It is not surprising then that teachers have to a large extent left the exploration of the spiritual to one side. If they are unsure of what is meant by the term they are hardly likely to build it into the daily curriculum of the children. I would argue that for any talk of the spiritual to make sense in practical terms it is essential that some understanding of the notion is arrived at. We cannot hope to begin developing the spiritual in children unless we have some idea of what it is we are trying to develop.     

Surrogate Motherhood, Rights and Duties: A Reply to Campbell

In a recent article in Health Care Analysis (Vol. 8, No. 1),Campbell misrepresents our specific arguments about commercialsurrogate motherhood (C.S.M.) and our general philosophical andpolitical views by saying or suggesting that we are `Millsian'liberals and consequentialists. He gives too the false impressionthat we do not oppose, in principle, slavery and child purchase.Here our position on C.S.M. is re-expressed and elaborated uponin order to eliminate possible confusion. Our general ethical andphilosophical framework is also outlined and shown to be otherthan Campbell says that it is. In particular, a moral philosophythat it is based on neither consequentialism nor Kantianism ispresented. C.S.M., it is argued, is not child purchase. It is like it insome respects and unlike it in others. It is unlike it in therespects which, relative to the present discussion, matter.     

The values of dramatic play in children

The value of dramatic play seems to lie in five basic functions: 1) it provides personal expression and catharsis of inner desires; 2) it helps the child to distinguish between reality and fantasy; 3) it provides for children's social adaptation: 4) it is dynamic for learning; and 5) it improves intellectual development and specifically creativity, through interaction, transformation and imagination. Generally, dramatic play is fundamental to emotional, social and intellectual development of children.

Why Family Professionals Can No Longer Ignore Violence Toward Animals*

The issue of violence to animals has been virtually ignored by family scholars and other family professionals. After looking at why animal abuse has not received attention, it is argued that those who study and work with families need to attend to animal abuse for seven reasons: (a) animal abuse is a serious antisocial behavior by children and adolescents; (b) it is a relatively common childhood occurrence; (c) it has potential negative developmental consequences; (d) violence toward animals is related to interpersonal violence; (e) it is connected to and may be a marker of family violence; (f) the well‐being of companion animals is being neglected; and (g) it will help achieve a less violent society. The implications for research, policy, counseling and human services, and family life education are discussed.     

An Argument for the use of Aristotelian Method in Bioethics

The main claim of this paper is that the method outlined and used in Aristotle’s Ethics is an appropriate and credible one to use in bioethics. Here “appropriate” means that the method is capable of establishing claims and developing concepts in bioethics and “credible” that the method has some plausibility, it is not open to obvious and immediate objection. It begins by suggesting why this claim matters and then gives a brief outline of Aristotle’s method. The main argument is made in three stages. First, it is argued that Aristotelian method is credible because it compares favourably with alternatives. In this section it is shown that Aristotelian method is not vulnerable to criticisms that are made both of methods that give a primary place to moral theory (such as utilitarianism) and those that eschew moral theory (such as casuistry and social science approaches). As such, it compares favourably with these other approaches that are vulnerable to at least some of these criticisms. Second, the appropriateness of Aristotelian method is indicated through outlining how it would deal with a particular case. Finally, it is argued that the success of Aristotle’s philosophy is suggestive of both the credibility and appropriateness of his method.     

Is the effect of alternative medical treatment only a placebo effect?

A common assertion about alternative medical technologies is that their results are solely built upon the placebo effect. The reason for this assertion is due to the facts that the placebo effect is perceived as an irrational quantity, and that the placebo effect is considered unspecific. If it is possible to rehabilitate the placebo effect by interpreting it as a specific effect, what consequences would it have for school medicine and the view of certain alternative medical technologies? To answer these questions it is necessary to investigate just what sort of phenomenon the placebo effect is, and what determines its dimensions.     

What do we mean by validating a prognostic model?

Prognostic models are used in medicine for investigating patient outcome in relation to patient and disease characteristics. Such models do not always work well in practice, so it is widely recommended that they need to be validated. The idea of validating a prognostic model is generally taken to mean establishing that it works satisfactorily for patients other than those from whose data it was derived. In this paper we examine what is meant by validation and review why it is necessary. We consider how to validate a model and suggest that it is desirable to consider two rather different aspects - statistical and clinical validity - and examine some general approaches to validation. We illustrate the issues using several case studies.
