Throughout much of the world, frog populations are declining and some species are disappearing totally. In Australia, several species have become extinct in the past 25 years. This revised and updated guide provides concise accounts of all the known frogs of Australia. There are 230 species within the five native frog families: Hylidae, Limnodynastidae, Microhylidae, Myobatrachidae and Ranidae. Also included are the introduced Cane Toad and nine ‘stowaway’ species that have arrived in Australia. The text for each species includes details of size, status, distribution, habitat, behaviour and advertisement call. Each species is accompanied by a map of Australia showing its known distribution, and a full-colour painted illustration. Closely related frogs are shown in identical poses so that comparisons can be made readily. The introductory section of the book covers frog biology and habitats and includes notes on families and genera.

Multiple introductions are warranted to this complex and unusual series. The first section describes its origins, its polymath editor C. K. Ogden, some of his related editorial ventures, and the books by some of the more prominent contributors. The distinctive futurological angle is discussed, together with its generally progressive orientation, and commitment to intelligent debate. The importance of the scientific approach is introduced, as a main thread running through the series and this study. Two superb, influential science volumes are introduced: the initial book, J. B. S. Haldane’s Daedalus; or, Science and the Future (1923); and J. D. Bernal’s The World, the Flesh, and the Devil (1929). Some cardinal intellectual contexts are established: how the series addresses time, eugenics, and modernity. Its organization is considered. The contemporary impact is assessed, leading to a discussion of the value of studying past predictions for thinking not only about the past but about the nature of prediction. The second introductory section places the series in the history of futurological thinking from the fin de siècle to the present. It starts from a contrast between today’s data-driven professionalized group foresight exercises and individual imaginative projections.

Advances in camera technology and digital instrument control have meant that in modern microscopy, the image that was, in the past, typically recorded on a piece of film is now recorded directly into a computer. The transfer of the analog image seen in the microscope to the digitized picture in the computer does not mean, however, that the problems associated with recording images, analyzing them, and preparing them for publication, have all miraculously been solved. The steps involved in the recording an image to film remain largely intact in the digital world. The image is recorded, prepared for measurement in some way, analyzed, and then prepared for presentation.Digital image acquisition schemes are largely the realm of the microscope manufacturers, however, there are also a multitude of “homemade” acquisition systems in microscope laboratories around the world. It is not the mission of this tutorial to deal with the various acquisition systems, but rather to introduce the novice user to rudimentary image processing and measurement.


This paper critically analyzes the symbolic use of rain in A Farewell to Arms (1929). The researcher has applied the Sapir-Whorf Hypothesis as a research tool for the analysis of the text. This hypothesis argues that the languages spoken by a person determine how one observes this world and that the peculiarities encoded in each language are all different from one another. It affirms that speakers of different languages reflect the world in pretty different ways. Hemingway’s symbolic use of rain in A Farewell to Arms (1929) is denotative, connotative, and ironical. The narrator and protagonist, Frederick Henry symbolically embodies his own perceptions about the world around him. He time and again talks about rain when something embarrassing is about to ensue like disease, injury, arrest, retreat, defeat, escape, and even death. Secondly, Hemingway has connotatively used rain as a cleansing agent for washing the past memories out of his mind. Finally, the author has ironically used rain as a symbol when Henry insists on his love with Catherine Barkley while the latter being afraid of the rain finds herself dead in it.

The world-wide use of scleral contact lenses has dramatically increased over the past 10 year and has changed the way that we manage patients with corneal irregularity. Successfully fitting them can be challenging especially for eyes that have significant asymmetries of the cornea or sclera. The future of scleral lens fitting is utilizing corneo-scleral topography to accurately measure the anterior ocular surface and then using software to design lenses that identically match the scleral surface and evenly vault the cornea. This process allows the practitioner to efficiently fit a customized scleral lens that successfully provides the patient with comfortable wear and improved vision.

Over the past century, democracy spread around the world in turbulent bursts of change, sweeping across national borders in dramatic cascades of revolution and reform. This book offers a new global-oriented explanation for this wavelike spread and retreat—not only of democracy but also of its twentieth-century rivals, fascism, and communism. The book argues that waves of regime change are driven by the aftermath of cataclysmic disruptions to the international system. These hegemonic shocks, marked by the sudden rise and fall of great powers, have been essential and often-neglected drivers of domestic transformations. Though rare and fleeting, they not only repeatedly alter the global hierarchy of powerful states but also create unique and powerful opportunities for sweeping national reforms—by triggering military impositions, swiftly changing the incentives of domestic actors, or transforming the basis of political legitimacy itself. As a result, the evolution of modern regimes cannot be fully understood without examining the consequences of clashes between great powers, which repeatedly—and often unsuccessfully—sought to cajole, inspire, and intimidate other states into joining their camps.

This book lays out a vision for how we should theorize about justice in a diverse society. It shows how free and equal people, faced with intractable struggles and irreconcilable conflicts, might share a common moral life shaped by a just framework. The book argues that if we are to take diversity seriously and if moral inquiry is sincere about shaping the world, then the pursuit of idealized and perfect theories of justice—essentially, the entire production of theories of justice that has dominated political philosophy for the past forty years—needs to change. Drawing on recent work in social science and philosophy, the book points to an important paradox: only those in a heterogeneous society—with its various religious, moral, and political perspectives—have a reasonable hope of understanding what an ideally just society would be like. However, due to its very nature, this world could never be collectively devoted to any single ideal. The book defends the moral constitution of this pluralistic, open society, where the very clash and disagreement of ideals spurs all to better understand what their personal ideals of justice happen to be. Presenting an original framework for how we should think about morality, this book rigorously analyzes a theory of ideal justice more suitable for contemporary times.

Abstract The Tour de France, a three week bicycle race has a unique place in the world of sports. The 100th edition of the event took place in 2013. In the past of 110 years of its history, people noticed unique stories and duels in particular periods, celebrities that became legends that the world of sports will never forget. Also many places where the races unfolded made history in the Tour de France. In this article we tried to point out the spatial context of this event using advanced technologies for distribution of historical facts over the Internet. The Introduction briefly displays the attendance of a particular stage based on a regional point of view. The main topic deals with selected historical aspects of difficult ascents which every year decide the winner of Tour de France, and also attract fans from all over the world. In the final stage of the research, the distribution of results on the website available to a wide circle of fans of this sports event played a very significant part (www.tdfrance.eu). Using advanced methods and procedures we have tried to capture the historical and spatial dimensions of Tour de France in its general form and thus offering a new view of this unique sports event not only to the expert community, but for the general public as well.
