Raised Beaches

Amongst the many objects of interest to the naturalist in that remarkable limb of the Western Highlands, variously written “Cantyre,” “Cantire,” or “Kintire,” are the raised beach and seaworn rocks which may be traced all along the coast under varying forms and aspects. This beach is the same as that which has been described by various writers as skirting the coast of Scotland from the Roman Wall northward, and winding through the innumerable fiords and sea-locks of the Firth of Clyde and the western coast; and to which attention was first called, I think, by Mr. Smith of Jordanhill, in 1836 and 1838, in papers read before the Geological and Wernerian Societies, and with other memoirs condensed into a small volume, in 1862. It is the last and by far the most strongly pronounced of all the raised beaches of Scotland—of which there are several—and is very graphically described by Mr. Geikie in his recent work. Now it is worthy of remark, that each of these authors draws opposite conclusions regarding the age of this raised beach from the same evidence; for Mr. Smith, of Jordanhill, considers the beach to be more ancient than the Roman period, and Mr. Geikie, on the contrary, more recent, both appealing to the position of the Roman Wall at its termination on the western and eastern coasts as evidence of the correctness of their views.

A major limitation of current dedicated impact energy management structures and passive devices used in the transportation industry is that their starting volume is their maximum volume, i.e. they dissipate energy by crushing or stroking from a larger to a smaller volume. Since they occupy their maximum volumes in their uncrushed-as-installed state they occupy space that is then only functional in an impact and is otherwise wasted. This limitation has led to the proposal of a class of "smart" impact energy management devices, based on unexpanded aluminum honeycomb (HOBE), that initially occupy a small volume and based on sensor input are rapidly expanded to a much larger crushable volume (nominally 75 times greater) just prior to or in response to an impact. Energy management devices based on this technology, should this technology successfully pass through the many steps needed to prove its viability, would thus allow empty space to be left adjacent to them for operational clearances, serviceability and repair functions, etc. which spaces would yet be fully utilized, due to the expansion of the device, for impact energy management. This paper documents the second portion of an experimental exploration of the viability of this technology. The specific goal of the here-in documented portion of the test program was the demonstration that the crush response of the rapidly expanded honeycomb is comparable to that of the standard pre-expanded commercial product.

Recent work on the osmotic pressure of the hen’s egg has introduced a sense of uncertainty as to the value of the many comparisons which have been made between osmotic pressures of the blood, body fluids, and surrounding media. The uncertainty pertains not to theory but to a simple matter of fact and, as this involves that most fundamental datum for biological theory—viz., the state of the water in the living cell—there is urgent need to have it cleared up. The fact in dispute is the freezing point of the yolk and white of the bird’s egg. Atkins in 1909 by measurements, obviously made with the greatest care, found “no difference between the freezing point of white and yolk of the same egg and a mixture of white and yolk gave the same depression.” Atkins (1909) used the ordinary Beckmann technique and so, too, did Straub (1929) twenty years later, but with a surprisingly different result for he found a constant difference between white and yolk of the hen’s egg amounting on the average to —0·15° C. A. V. Hill (1930) confirmed Straub’s (1929) finding by a different method. He compared the fall in temperature caused by evaporation with that of water and from the difference calculated the osmotic pressure. Howard (1932) using the Beckmann method again found no difference in the freezing point of white and yolk. In these measurements the yolk was puddled by stirring so that at sometime or another the structure was broken down. Yolk is not only a chemical complex but it is alive, gross mechanical disturbance might, therefore, have the effect it usually has on living cells and cause chemical breakdown with consequent fall of the freezing point. Hale’s experiments were designed to explore this possibility by observing directly the freezing point of intact yolk and white.

The design of tribological interfaces is often motivated by a quest to minimize friction and wear. Among the many strategic design principles that have been developed to this end, the simple idea of decoupling frictional force from normal load is especially attractive. Recent work from this laboratory demonstrates that under certain conditions, it is possible to reduce this coupling significantly with the result that the friction coefficient appears to be very low. However, the materials design requirements to achieve this end are rather stringent. Furthermore, modern methods enable one under some conditions to measure directly the structure and motions of lubricants during tribological sliding.

AbstractGreek-speaking people have been sailing the Mediterranean for millennia. At various stages of their development from Latin, the Romance languages have been influenced by their idiom. In Italy and in its islands, this role has been particularly evident due to the many rich and culturally active colonies in Southern Italy before and during the Roman period on the one hand, and through the later Byzantine occupation, which lasted several centuries in some areas, on the other. In this article, after a brief summary of the historical background (2.), the characteristics of the lexical borrowings from Greek in the local idioms of Southern (3.) as well as of Central and Northern Italy (4.) will be sketched. Here and there, and in the conclusions (5.), the status quaestionis and the latest orientations of the research will also be broadly outlined.

Human creativity intuitively seems beyond the reach of molecular, cellular, and circuit neuroscience. However, in this chapter, the authors propose that mechanisms that link memories across time have a critical role in a key aspect of human creativity, namely, the many ways in which distinct memories acquired on separate occasions can be related and connected in novel and generative ways. Recent work in mice suggests a detailed molecular, cellular, and systems neuroscience mechanism of memory linking that provides a framework for this key component of creativity in humans. This proposal shares some interesting features with psychological and systems-neurobiological accounts of human creativity but differs from such accounts since data in support of it are drawn from controlled interventional experiments in mice. Yet this purely mechanistic account raises a philosophical dilemma based on the intuitive differences between “mechanism” and “creativity.” The authors conclude the chapter with a brief exploration of this dilemma and its potential implications for a scientific explanation of the human creative process.

The importance of conjugacy classes for the structure of finite groups was recognised very early in the study of groups. In this survey we consider the results from the many articles which have developed this topic and examined the influence of conjugacy class sizes or the number of conjugacy classes on the structure of finite groups. Whilst we begin by mentioning the early results of Sylow and Burnside, our major objective is to highlight the more recent work and present some interesting questions which we hope will inspire further research.

General Appearance

The Little Pueblo of Tiripetío lies at the foot of a mountain near Morelia in the state of Michoacán. Its Indian name means “place of gold”, but the adobe houses with their straw roofs plus a general appearance of shabbiness belie such a title. Tiripetío, however, was not always a ghost town. In the sixteenth century it pulsed with life and activity. The life of the place centered about a convent of Augustinian friars, with its adjoining church, hospital and school. The name Vera Cruz is closely linked with this convent and school as with many other educational activities in sixteenth century Mexico. But like Tiripetío itself, which marked the scene of his early labours, the name of Alonso de la Vera Cruz has fallen into obscurity and today counts little, even with historians of his own Order. The recent work of Oswaldo Robles, a translation of one of Vera Cruz’s philosophic treatises, the Physica Speculano, (vd. The Americas, October 1944, under article: “Fray Alonso de la Vera Cruz and the Beginnings of Philosophic Speculation in the Americas”.) is truly a step in the right direction. It can only be hoped that the relatively settled political set-up in Mexico will open the way for a more thorough search for historical data on outstanding figures like Alonso de la Vera Cruz. The present article attempts, from the sources now at hand, to synthesize the many and varied activities in the field of education in which Vera Cruz engaged and to give an interpretation of the influence he exerted in the field of learning and in the development of the philosophic thought of his day in Mexico.

A large and growing body of work has documented large, robust illusions of area perception in adults. To date, however, there has been surprisingly little in-depth investigation into children’s area perception, despite the importance of this topic to the study of quantity perception more broadly (and to the many studies that have been devoted to studying children’s number perception). Here, in order to understand the interactions of number and area on quantity perception, we study both dimensions in tandem. First, inspired by recent work showing that human adults appear to rely on an 'Additive Area Heuristic', we test whether children may rely on this same kind of heuristic. Indeed, ‘additive area’ explains children’s area judgments better than true, mathematical area. Second, we show that children’s use of ‘additive area’ biases number judgments. Finally, to isolate ‘additive area’ from number, we test children’s area perception in a task where number is held constant across all trials. We find something surprising: even when there is no overall effect of ‘additive area’ or ‘mathematical area’, individual children adopt, and stick to, specific strategies throughout the task. In other words, some children appear to rely on ‘additive area’, while others appear to rely on true, mathematical area — a pattern of results that may be best explained by a misunderstanding about the concept of cumulative area. We discuss how these findings raise both theoretical and practical challenges of studying quantity perception in young children.

This article addresses issues that lie at the intersection of debates about language, Hip Hop Culture, and globalization. Critically synthesizing a wide range of recent work on Hip Hop and foregrounding issues of youth agency as evidenced by Hip Hop youth’s metalinguistic theorizing, the article presents an empirical account of youth as cultural theorists. Hip Hop youth are both participants and theorists of their participation in the many translocal style communities that constitute the Global Hip Hop Nation. Highlighting youth agency, the article demonstrates that youth are engaging in the agentive act of theorizing the changes in the contemporary world as they attempt to locate themselves at the intersection of the local and the global. The article concludes by calling for a linguistic anthropology of globalization characterized by ethnographic explorations of and a theoretical focus on popular culture, music, and mass-mediated language as central to an anthropological understanding of linguistic processes in a global era.

This paper surveys archaeological work on Greek sanctuaries of the Roman period conducted over the past 20 years. Previously largely ignored or simply overlooked, in recent times the Roman phases of sanctuaries have seen a tremendous amount of excavation and research work, mirroring the increased interest in the archaeology of Roman Greece as a whole. In addition to brief presentatons of new and recent archaeological discoveries and material studies, this survey also aims to highlight the importance of current work based on the re-examination of sites excavated long ago and the contribution of various strands of archaeological evidence to an enhanced understanding of the history and function of Greek sanctuaries from the time of the Roman conquest to Late Antiquity.
