Velocity measurements on cracks in sapphire and glass have been made using Wallner lines. Contrary to the view that crack-branching in a given material occurs at a constant critical velocity, it is found that the branching velocity can vary with the stress on the crack. On the other hand, AfCb1/2 is constant. Here Af is the stress normal to the crack and Cb is the semi-length of a double-ended crack when it branches. A theory is given in terms of the (...) condition for inducing persistent growth of a new crack ahead of the running crack. (shrink)

According to familiar accounts, Rousseau held that humans are actuated by two distinct kinds of self love: amour de soi, a benign concern for one's self-preservation and well-being; and amour-propre, a malign concern to stand above other people, delighting in their despite. I argue that although amour-propre can (and often does) assume this malign form, this is not intrinsic to its character. The first and best rank among men that amour-propre directs us to claim for ourselves is that of occupying (...) 'man's estate'. This does not require, indeed it precludes, subjection of others. Amour-propre does not need suppression or circumscription if we are to live good lives; it rather requires direction to its proper end, not a delusive one. (shrink)

Scientific and technological advances are lending pressure to expand the scope of newborn screening. Whereas this has great potential for improving child health, it also challenges our current perception of such programmes. Standard newborn screening programmes are clearly justified by the fact that early detection and treatment of affected individuals avoids significant morbidity and mortality. However, proposals to expand the scope and complexity of such testing are not all supported by a similar level of evidence for unequivocal benefit. We argue (...) that screening for genetic susceptibility to complex disorders is inherently different from standard screening and, while of potential value, must be considered separately from conventional testing.

Anthropologists and linguists have long been aware that the body is explicitly referred to in conventional description of emotion in languages around the world. There is abundant linguistic data showing expression of emotions in terms of their imagined ‘locus’ in the physical body. The most important methodological issue in the study of emotions is language, for the ways people talk give us access to ‘folk descriptions’ of the emotions. ‘Technical terminology’, whether based on English or otherwise, is not excluded from (...) this ‘folk’ status. It may appear to be safely ‘scientific’ and thus culturally neutral, but in fact it is not: technical English is a variety of English and reflects, to some extent, culture-specific ways of thinking (and categorising) associated with the English language. People — as researchers studying other people, or as people in real-life social association — cannot directly access the emotional experience of others, and language is the usual mode of ‘packaging’ one’s experience so it may be accessible to others. Careful description of linguistic data from as broad as possible a cross-linguistic base is thus an important part of emotion research. All people experience biological events and processes associated with certain thoughts (or, as psychologists say, ‘appraisals’), but there is more to ‘emotion’ than just these physiological phenomena. Speakers of some languages talk about their emotional experiences as if they are located in some internal organ such as ‘the liver’, yet they cannot localise feeling in this physical organ. This phenomenon needs to be understood better, and one of the problems is finding a method of comparison that allows us to compare descriptions from different languages which show apparently great formal and semantic variation. Some simple concepts including feel and body are universal or near-universal, and as such are good candidates for terms of description which may help to eradicate confusion and exoticism from cross-linguistic comparison and semantic typology. Semantic analysis reveals great variation in concepts of emotion across languages and cultures — but such analysis requires a sound and well-founded methodology. While leaving room for different approaches to the task, we suggest that such a methodology can be based on empirically established linguistic universal (or near-universal) concepts, and on ‘cognitive scenarios’ articulated in terms of these concepts. Also, we warn against the danger of exoticism involved in taking all body part references ‘literally’. Above all, we argue that what is needed is a combination of empirical cross-linguistic investigations and a theoretical and methodological awareness, recognising the impossibility of exploring other people’s emotions without keeping language in focus: both as an object and as a tool of study.

How do we refer to people in everyday conversation? No matter the language or culture, we must choose from a range of options: full name ('Robert Smith'), reduced name ('Bob'), description ('tall guy'), kin term ('my son') etc. Our choices reflect how we know that person in context, and allow us to take a particular perspective on them. This book brings together a team of leading linguists, sociologists and anthropologists to show that there is more to person reference than meets (...) the eye. Drawing on video-recorded, everyday interactions in nine languages, it examines the fascinating ways in which we exploit person reference for social and cultural purposes, and reveals the underlying principles of person reference across cultures from the Americas to Asia to the South Pacific. Combining rich ethnographic detail with cross-linguistic generalizations, it will be welcomed by researchers and graduate students interested in the relationship between language and culture.

This note discusses critically a point in a d m walker's paper "the ideal of sincerity" ("mind", October 1978). Walker claims that desires are insincere if corrupted by incompatible desires. This view accounts for some cases, But not for all. It is argued, In the note, That superficial, Factitious, 'got up' desires are judged insincere as such because not 'natural' to a man. This is implied by the claim of andre gide's which walker misinterprets. The issue of natural desires in (...) contrast to artificial desires introduces the question of 'authenticity', Which is looked at in connection with lionel trilling's "sincerity and authenticity".

"Contemporary Mind - Some Modern Answers" is a fantastic collection of essays by English science writer John W. Sullivan. They deal with a range of subjects, ranging from mysticism and immortality to the relationship between science and art. John William Navin Sullivan (1886 - 1937) was a literary journalist and popular science writer most famous for his study of Beethoven. He is also responsible for having written some of the earliest non-technical accounts of Einstein's General Theory of Relativity, and he (...) was acquainted with many important writers in London in the 1920s, including John Middleton Murry, Aldous Huxley, Wyndham Lewis, Aleister Crowley and T. S. Eliot. Other notable works by this author include "Aspects of Science" (1923), "Aspects of Science: Second Series" (1926), and An Outline of Modern Knowledge (1931). Contents include: "The Balanced Life," "The Problem of Suffering," "The Necessity of Mysticism," "Human Immortality," "A Dissertation on Beethoven," "The Scientific Outlook," "A Dissertation on Maxwell," "New Principles," "A Dissertation on Newton," "Science and Art," "Mathematics and Culture," "Sir Josiah Stamp," "Mr. Aldous Huxley," etc. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with the original text and artwork. (shrink)

In the six remarkable elegidia transmitted in the Tibullan corpus as 3.13–18 we appear to possess the writings of an educated Roman woman of aristocratic family and high literary connections: a woman, moreover, who participates as an equal in one of the most distinguished artistic salons of the age, and composes poetry in an obstinately male genre on the subject of her own erotic experience, displaying a candour and the exercise of a sexual independence startingly at odds with the ideology (...) of her class. Such a figure is either, depending on one's viewpoint, too good to be true or too embarrassing to be tolerated. The case could easily be put that Sulpicia, more perhaps even than Sappho, has found her poems condemned by accident of gender to a century and a half of condescension, disregard, and wilful misconstruction to accommodate the inelastic sexual politics of elderly male philologists. Certainly even the most sympathetic of recent comment is prone to lapse into a form of critical language outlawed in Catullan scholarship thirty years ago. Yet feminist critics have been strangely cautious in their response. A scholar who rose swiftly to the defence of Erinna when that elusive poet's identity was impugned has notoriously written of Sulpicia: ‘She was not a brilliant artist: her poems are of interest only because the author is female.’ Five years late, Sulpicia has found a place in the major sourcebook on ancient women, but with the cycle of poems violently reordered after the judgment of a nineteenth-century critic, anxious to restore his poetess's chastity against the disconcerting frankness of the texts.

Bede's Ecclesiastical History is the most important single source for early medieval English history. Without it, we would be able to say very little about the conversion of the English to Christianity, or the nature of England before the Viking Age. Bede wrote for his contemporaries, not for a later audience, and it is only by an examination of the work itself that we can assess how best to approach it as a historical source. N.J. Higham shows, through a close (...) reading of the text, what light the Ecclesiastical History throws on the history of the period and especially on those characters from seventh- and early eighth-century England whom Bede either heroized, such as his own bishop, Acca, and kings Oswald and Edwin, or villainized, most obviously the British king Cædwalla but also Oswiu, Oswald's brother. In (Re-)Reading Bede, N.J. Higham offers a fresh approach to how we should engage with this great work of history. He focuses particularly on Bede's purposes in writing it, its internal structure, the political and social context in which it was composed and the cultural values it betrays, remembering always that our own approach to Bede has been influenced to a very great extent by the various ways in which he has been both used, as a source, and commemorated, as man and saint, across the last 1,300 years.

Language is shaped by its environment, which includes not only the brain, but also the public context in which speech acts are effected. To fully account for why language has the shape it has, we need to examine the constraints imposed by language use as a sequentially organized joint activity, and as the very conduit for linguistic diffusion and change.

Did Alcidamas invent the story of the contest of Homer and Hesiod? Martin West has argued that he did , 433 ff.). I believe that there are a number of reasons for thinking this improbable. The stories of the deaths of Homer and Hesiod were traditional before Alcidamas. Heraclitus knew the legend of the riddle of the lice and Homer's death , and the story of Hesiod's death was well known by Thucydides’ time . The first attempt to record information (...) about Homer's life is ascribed to Theagenes of Rhegium, in the late sixth century b.c. . By that time it seems likely that there was already a considerable body of legends about the early poets. The pieces of hexameter verse in the Herodotean Life of Homer, some of which show detailed knowledge of the area around Smyrna in the archaic period, probably date from before 500 b.c. In relating the stories of the poets’ deaths Alcidamas is recording the results of στορα, and this is what he implies in Michigan papyrus 2754 . West's theory requires one to assume that he has incorporated with these traditions his own fiction of the contest. This seems to me to go against what we know in general about the activity of sophists such as Alcidamas. Although they were capable of inventing myths , there is no evidence that they created such stories about earlier historical figures, rather than collecting popular legends about them, and using these for their own purposes. It is true that Critias used the evidence of Archilochus’ own poetry to draw conclusions about his life . But this is not the same as inventing a story virtually from scratch. Hesiod's own testimony about his poetic victory , the original starting-point for the legend of the contest with Homer, did not on its own provide a basis from which such inferences could be drawn. It seems more likely that the legend is the product of earlier popular embroidery, at a time when speculation about these early poets’ lives was becoming common. (shrink)
