‘What is an amphibian?’ provides an overview of amphibians, which zoologists divide into three very unequal sized Orders. The great majority are the frogs and toads, which make up the order Anura, a name that refers to the lack of a tail. The second amphibian order are the salamanders and newts, called the Urodela. Meanwhile, the third amphibian order, the Caecilia, are best known for being poorly known, thanks to their remote distribution and obscure habitat. There are four methods that amphibians can use to breathe: cutaneous respiration, bucco-pharyngeal respiration, pulmonary respiration, and branchial respiration.

Although the debate on the nature of ‘knowledge’ and ‘information’ is far from settled, it is now taken for granted throughout the academic world that the two notions are related but fundamentally distinct. This result, and its significant consequences, still need to be realised and understood by the great majority of the business world. In the first section of this chapter, we briefly comment on some characteristic views of ‘knowledge’ and ‘knowledge management,’ and subsequently we analyse in-depth the core constituent notion of the latter, that is, knowledge. In section two, we outline three major consequences of our analysis. The first concerns the limits of management for a certain class of activities involving knowledge. The second concerns the scope and limits of technology for the same class of activities. The third concerns the issue of knowledge market. The thesis we develop is that knowledge cannot be taken as a commodity; in other words, the notion of a knowledge market is not implementable.

At the Third Pan-African Congress on Prehistory, held in Livingstone in 1955, there was a symposium on the early Pebble Cultures of Africa. It became apparent from the discussion that followed that there was considerable divergence of opinion among prehistorians as to the criteria that distinguished artificial from natural fracture. Specimens that were acceptable as artifacts to some were not acceptable to others and it became clear that considerably more research was necessary into the way in which nature can fracture stone by percussion and in particular into the natural fracture of pebbles. It is especially important to know whether nature can simulate Kafuan- and Oldowan-type pebble tools. This is because the great majority of Kafuan tools from the type areas are abraded, often considerably, although Lowe mentions that Kafuan tools occur unrolled in the 175-foot terrace in the Kafu river as also in the 270-foot terrace in the Kagera Valley.

The convening of the Assembly of Notables and the prolonged conflict between the government and the Parlement of Paris gave rise to a ferment of discussion throughout France during 1787 and 1788. This increased after the publication of the arrêt du conseil on 8 August 1788 which gave 1 May 1789 as the date for the opening of an Estates-General. The public debate was greatly encouraged by, and indeed largely carried on in, the innumerable pamphlets which appeared after the king had, in July, invited informed persons to submit memoranda on the proper form and functions of such an assembly. Amid this ‘avalanche of proposals, complaints, protests and far-fetched schemes’ there were a considerable number of pamphlets written by members of the lower clergy. Although the great majority of these are anonymous, the form of the titles and, more important, internal evidence indicate that they are almost certainly the work of clerical writers. The nature and content of these pamphlets are a valuable indication of the attitude of at least a considerable section—and this an influential section—of the lower clergy on the eve of the Revolution. In these pamphlets are expressed in their clearest form the ideas which formed the content of many of the speeches made by curé agitators in the electoral assemblies which met in the spring of 1789, and which, modified in more sober committees, dictated many of the clauses which clerical cahiers devoted to Church affairs.

By the best musical standards the average school concert programme makes dismal reading. The School Orchestra will play the usual Haydn Minuets and Handel Gavottes, with perhaps an imitation Pomp and Circumstance March thrown in. The School Choir will sing some folk songs, as well as some pieces by Bach, Mozart and Schubert; there is nothing to complain of here, but what about the dreary group of so-called modern songs at the end of the programme? No doubt a song or two by Vaughan Williams and Arthur Benjamin will be found, but otherwise the usual things are there: Fairies in the Glen and Flowers in the Spring: and to finish with, the highly moral one with plenty of uplift; there are dozens that fit in here, so there is no need to mention titles. But where is the music of our real modern composers? By modern composers I don't mean the school music masters, church organists, or “educational” composers who at this minute doubtless are turning out another uplifting song for massed unison voices, but the real composers, those who are sometimes in evidence on the Third Programme and at the Cheltenham Festival. It appears that our real composers are not very interested in writing music for our school children to sing and play. True, some have shown the way: Bartók, Kodály, Copland, Vaughan Williams, Britten have all made considerable and worthwhile contributions to this particular field. But where are the rest? The great majority of them are not “Ivory Tower” artists, and yet even in the concert programmes of those schools which are musically enterprising their names seldom if ever appear.

Nature leads the way. Man emerges on the scene, follows her footprints, marks and registers them in language, and makes a Science of Nature. Then he looks back and discovers that Language, while following the path of Nature, has left a trail of her own. He returns on this new trail, again marks and registers its footprints, and makes a Science of Language.The Birth of Language (1937)The great majority of linguists in Canada today belong to only the second academic generation of linguists in Canadian universities. Members of the first generation are, of course, still active—in some cases more active than the younger members of their departments. They are characterized, roughly, as founding members of the Canadian Linguistic Association, or as members of long standing. They are also characterized in a few cases as having been the teachers of junior members of the profession, although this is less often the case than it is in other disciplines, partly because there have been very few graduate programs in Linguistics until recently, and partly because there has been little demand for linguists trained in the specialty of the first generation anyway, which is almost unanimously dialect geography, and partly because there has been a decided tendency toward hiring non-Canadians in the social sciences to fill positions in Canadian universities. Now, with the increase in graduate programs in Linguistics, the more diverse specializations, and the national consciousness that Canadian universities can also be served by Canadians, the third generation of linguists will increasingly be selected from the students of the present academic generation, which is how academic generations have been gauged in other cultures for centuries.

The influence of Augustine on Western philosophy is exceeded in duration, extent and variety only by that of Plato and Aristotle. Augustine was an authority not just for the early Middle Ages, when he was often the lone authority, but well into modern times. He was in many ways the principal author in contention during the Reformation and Counter-Reformation, and in France alone he was variously received by authors as diverse as Montaigne, Descartes, Malebranche, Arnauld and Pascal. The breadth of Augustine’s influence makes it difficult to give precise sense to the term ‘Augustinianism’, even when considering only a single period. Historians of medieval philosophy use the term ‘Augustinianism’ to describe three rather different relations to the thought of Augustine. The first relation is a comprehensive dependence on Augustine both for philosophical principles or arguments, and for instruction in the topics and procedures of ancient philosophy. Augustine serves as the trustworthy guide to philosophy as a whole. The second kind of relation is a defence of specific Augustinian teachings in the face of rival teachings, most especially those of Aristotle. These Augustinian teachings include the function of divine ideas in knowledge, the unity of the human soul’s essential powers, and the unfolding of potential intelligibilities in material substances. The third relation is the reappropriation of Augustinian principles, especially those of his later writings, to address quandaries newly formulated with the tools of nominalist semantics and the mathematics of continuities. Among these quandaries are the contingency of future human actions and the certainty of human cognition. These three relations to Augustine can be found in texts throughout the medieval period. They are not neatly correlated with particular centuries, but one or another does tend to be predominant at different times. Thus the first relation, of comprehensive dependence, is seen in the great majority of Latin writers on philosophic topics through the twelfth century. The second relation, of topical defence, appears prominently during the thirteenth-century contest between so-called ‘Augustianians’ and ‘Aristotelians’. The third relation, of reappropriation in reaction to newly formulated quandaries, is found particularly in writings of the fourteenth century and beyond.

Since the phenomena of the absorption of light by coloured media began to be studied with attention, various philosophers have regarded them as inexplicable by the theory of the colours of thin plates, and have consequently regarded Sir Isaac Newton’s theory of the colours of natural bodies as either defective in generality, or altogether unfounded. Mr. Delaval was the first person who brought an extensive series of experiments to bear upon this subject. Dr. Thomas Young considered it “impossible to suppose the production of natural colours perfectly identical with those of thin plates,” unless the refractive density of the particles of colouring bodies was at least twenty or thirty times as great as that of glass or water, which he con­sidered as “difficult to believe with respect to any of their arrangements constituting the diversities of material substances.” Sir John Herschel has expressed a still more decided opinion upon this subject. He regards “the speculations of Newton on the colours of natural bodies” as only “a premature generalization,” and "limited to a comparatively narrow range; while the phenomena of absorption, to which he considers the great majority of natural colours as referable, have always appeared to him to constitute a branch of photology sui generi .” The general opinion advanced by these three philosophers I have long entertained; and with the view of supporting them I have analysed a great variety of colours which are exhibited by the juices of plants. In a paper "On the Colours of Natural Bodies,” I have shown that the green colour of plants, the most prevalent of all the colours of natural bodies, in place of being a green of the third order , as Newton and his com­mentators assert, is a colour of no order whatever, and having in its composition no relation at all to the colours of thin plates.

Burns are the third most important cause of accidental death in childhood, outranked only by automobile casualties and drownings1. In the United States 12,000 deaths occur annually, but over the same period 2,000,000 patients are hospitalized for burns2. Among these, a very large numher of children must undergo prolonged, painful, and restrictive hospitalization from which they emerge with scars to both body and personality profoundly affecting their social and emotional development. The tragedy is that the great majority of burn injuries are preventable. In the toddler stage the most common accident occurs when the youngster reaches up and pulls on a pot handle at the front of the stove, resulting in a scald of the extended arm, shoulder, and chest. With the advent of summer, burns from the outdoor barbecue become epidemic. These are flash flame burns of face, hands, arms, and chest, usually in boys, that follow explosive ignition of the outdoor fire on which the victim has poured gasoline, kerosene, or other highly flammable starter fluid. The pant-leg burn is prevalent during the autumn when the burning of leaves is common. At all seasons one encounters burns, principally of the chest when the loose, frilly nightdresses of young girls ignite from too close proximity with the open fire, gas range, or candelabrum. Mandatory treatment of cloth with fire retardants could greatly reduce the incidence of these injuries at a negligible cost. As early as possible children should be taught never to run should their clothing ignite but rather to fall to the ground and smother the fire by rolling.

Leo X and Leopoldo de ‘Medici, patrons and collectors of Raphael: three examples. Today, the great majority of Raphael’s works in the Uffizi exist thanks to the Medici art collections of the early 1500s to the early 1670s. It is therefore possible to assert that this Florentine family had a particular taste for Raphael’s works. However, not all the paintings collected in that time reflect the Medicis’ artistic interests, as many of them came from expropriations or bequests and inheritances. Despite this, one artistic genre, more than others, appears to be particularly representative of the Medici family’s interest: the portrait. The aim of this paper is to identify some trends concerning the Medicis’ taste in the portrait and self-portrait. In doing so, three artworks – preserved in the Gallerie degli Uffizi – will be examined here: the Portrait of Leo X with Cardinals Giulio de ‘Medici and Luigi de’ Rossi; the Portrait of Tommaso Inghirami, known as Fedra; and Raphael’s self-portrait. These examples show how the artistic execution of Raphael’s artworks, or their later inclusion in the Medici collection (following Raphael’s death), depended on two main Medici personalities, namely Leo X and the prince and cardinal Leopoldo. Moreover, such portraits also reflect the three main recurrent circumstances under which works would usually be included in the Medici collection. The first concerned the creation of the artwork through a direct relationship between patron and artist (and, here, reciprocal incentives from one to the other can be seen). The second had to do with a consolidated taste of the Medicis in creating a collection of artistic portraits and, here, the acquisition of the artwork perfectly reflects this artistic taste. In the third case, we will see how the desire for a complete collection of artistic self-portraits sometimes brought the collector to acquire artworks that did not exactly correspond to their tastes.
