Delivery. Speak clearly. Don't shout or whisper - judge the acoustics of the room.

Don't rush, or talk deliberately slowly. Be natural - although not conversational.

Deliberately pause at key points - this has the effect of emphasising the importance of a particular point you are making.

Avoid jokes - always disastrous unless you are a natural expert  

To make the presentation interesting, change your delivery, but not to obviously, eg:

• speed;

• pitch of voice.

Use your hands to emphasise points but don't indulge in to much hand waving. People can, over time, develop irritating habits. Ask colleagues occasionally what they think of your style.

Look at the audience as much as possible, but don't fix on an individual - it can be intimidating. Pitch your presentation towards the back of the audience, especially in larger rooms.

Don't face the display screen behind you and talk to it.

Avoid moving about too much. Pacing up and down can unnerve the audience, although some animation is desirable.

Keep an eye on the audience's body language. Know when to stop and also when to cut out a piece of the presentation.

Visual Aids. Visual aids significantly improve the interest of a presentation. However, they must be relevant to what you want to say. A careless design or use of a slide can simply get in the way of the presentation. What you use depends on the type of talk you are giving. Here are some possibilities:

• Overhead projection transparencies (OHPs);

• 35mm slides;

• Computer projection: PowerPoint, applications such as Excel, etc.;

• Video, and film;

• Real objects - either handled from the speaker's bench or passed around;

• Flip-chart or blackboard - possibly used as a 'scratch-pad' to expand on a point.

Keep it simple though - a complex set of hardware can result in confusion for speaker and audience. Slides and OHPs should contain the minimum information necessary. To do otherwise risks making the slide unreadable or will divert your audience's attention so that they spend time reading the slide rather than listening to you.

Study the texts given below, use additional information resources and deliver a report on your special field of knowledge.

The Nature of Law

The law affects us all from the moment we are born. We may not like it, but for better or for worse, we live in a society that is bound by rules.

Society, by one means or another, has developed a formal system of rules which are designed to be both observed and enforced. If an individual breaks a legal rule he or she will be penalised in some way. That is what the law is about: it consists of minimum standards of conduct which all members of society are expected to follow.

The concept of justice lies deep in the conscience of all civilized peoples. What that justice is, however, a reflection of the customs and laws of that civilization, and derives from the morality of the people as expounded by their law makers.

All civilized societies have had their codes of law, at least from the time of Hammurabi, the founder of the Babylonian Empire in the third millenium BC. Law is the latticework of civilization and throughout history a few outstanding law makers have shone forth like stars, to illumine the course of justice, some like Solomon as judges, others such as Justinian as great codifiers.

Yet the thought that there can be a theory of law, that is a set of systematically related true propositions about the nature of law, has been challenged, and from several directions. None of the challenges is entirely successful.

A theory of law in a narrow sense refers to an explanation of the nature of law. It is a sense central to philosophical reflection about the law throughout its history.

A theory of law is successful if it meets two criteria: First, it consists of propositions about the law which are necessarily true, and, second, they explain what the law is.

Naturally, the essential properties of the law are universal characteristics of law. They are to be found in law wherever and whenever it exists. Moreover, these properties are universal properties of the law not accidentally, and not because of any prevailing economic or social circumstances, but because there is no law without them.

The most usual meaning of the phrase 'the law' is that of a legal rule. Legal rules influence many different aspects of life. Secondly, “the law” is the complete body of all those individual rules that bind society together. Thirdly, the phrase may also mean the process by which rules are made and applied. The development, the content and the application of those rules add up to a legal system, complete with judges, courts, solicitors, barristers, police and indeed politicians in their role as law-makers (legislators).

The understanding (not definition) of such concepts as responsibility, liberty, authority, scientific knowledge, justice, right/wrong, etc. is a necessary prerequisite for answering some crucial questions about the regulation of social conduct and the conflicts derived from it:

• What are the principles and standards we should agree upon so that social life can unfold harmoniously on both local and planetary levels?

• Why are these principles and standards valid?

• What does each individual owe to the other individuals with whom he shares the social praxis?

• What is it that I, as an individual who interacts socially, can believe, or say or do?

• Which social ills could law attempt to lessen?

• How could this be achieved?

• For which social ills is each individual responsible and to what degree?

• Why am I responsible for the social consequences of my conduct?

At the end of the twentieth century we are forced to recognize:

• That law is in itself a culturally specific discursive form.

• That there is no pre-existent uniformity of values that explains a culture; there is cultural heterogeneity and multiplicity. Consequently,

• The authority of law based on a metanorm hierarchically superior to and underlying positive law, or on a social purpose legitimated by one culture only, has become increasingly problematic.

English law divides principally into two categories - criminal or public and civil or private. Criminal law concerns matters deemed by society to be so serious that in the event of a person transgressing a legal rule it is society itself which must punish the wrong-doer.

Civil law is concerned with disputes between individuals or indeed groups of individuals such as public companies and corporations. Society will lay down the framework of legal rules within which such disputes must be settled. But society itself is not a party to any legal proceedings; it acts more as a referee. Indeed the object of civil law is to compensate the injured party, rather than to punish the 'wrong-doer'. One individual sues another.

All that appears to imply that in terms of society's morality and values civil matters are less serious or less weighty than criminal issues.

It is possible to speak in terms of three branches of the law, the third being constitutional and administrative law. This area of legal rules covers such matters as the powers of Parliament and the Government, the powers of the police and the administration of justice, personal freedoms including race relations and immigration, and the freedoms of expression and assembly. The greater part of such administrative law will fall under civil law in the broadest sense and the rest under criminal law. Other countries take a different approach, however.

Law, far from being a complete and static system, is a dynamic system continually being created and modified. This condition of dynamism is already a commonplace in legal theory.

The law does not stand still. The public's attitudes and habits do change, human nature being an odd mixture of both the rational and the irrational, of both conservatism and radicalism. The legal system - including judicial outlook - has to accommodate itself to such shifts in the climate of opinions. Nonetheless the law may move slowly: change, whether societal or legal, is not necessarily rapid.
