Le 29 mai 1953, pour la première fois dans l'histoire des hommes, l'alpiniste Edmund Hillary et le sherpa Tenzig Norgay atteignent le sommet de l'Everest. Cette victoire, les deux héros la partagent avec les membres de l'expédition britannique à laquelle ils sont associés.
John Hunt, alpiniste chevronné et militaire anglais, dirigeait cette expédition victorieuse. Dans Victoire sur l'Everest, il relate avec brio et talent les préparatifs et les détails de l'ascension audacieuse, dangereuse et exaltante qui mena son équipe vers le sommet.
Cet ouvrage de référence, rédigé dans un style riche et vivant, est un magnifique récit d'aventure humaine et sportive.
This is the story of how, on 29 May, 1953, two men, both endowed with outstanding stamina and skill, reached the top of Everest and came back unscathed to rejoin their comrades. 'Yet this will not be the whole story, for the ascent of Everest was not the work of one day, nor even of those few anxious, unforgettable weeks in which we prepared and climbed this summer. It is, in fact, a tale of sustained and tenacious endeavour by many, over a long period of time... We of the 1953 Everest Expedition are proud to share the glory with our predecessors.'Sir John Hunt
So you think you want to be Agile. But what does it mean? How can you develop software in an agile manner? How can you reap the benefits of agile modelling or Extreme Programming (XP)? What tools might you use to help you become more agile? This book tells you!Agile software Construction reviews the leading agile development processes. It explains what each is and what they attempt to achieve. It also explains what they are not and dispels numerous myths surrounding agile development.Agile software construction itself is an attempt to put the software being developed first, and to acknowledge that user requirements change. It is agile because it can respond quickly to the users changing needs. In turn, agile software development puts the software first because almost any activity undertaken must be to the benefit of the software that will be delivered.This book will help you to determine if an agile approach is for you and which approach (or approaches) to adopt. It guides you in how to plan, organise and develop software systems in an Agile Manner. It introduces the core concepts in a concise and easily digested form, and evaluates how successful the core techniques can be, as well as what problems may be encountered. The book also shows how some of these problems have been overcome on real world projects by combining XP, Agile modelling and Feature Driven Development.
Scala is a new and exciting programming language that is a hybrid between object oriented languages such as Java and functional languages such as Haskell. As such it has its own programming idioms and development styles.Scala Design Patterns looks at how code reuse can be successfully achieved in Scala. A major aspect of this is the reinterpretation of the original Gang of Four design patterns in terms of Scala and its language structures (that is the use of Traits, Classes, Objects and Functions). It includes an exploration of functional design patterns and considers how these can be interpreted in Scala's uniquely hybrid style.A key aspect of the book is the many code examples that accompany each design pattern, allowing the reader to understand not just the design pattern but also to explore powerful and flexible Scala language features. Including numerous source code examples, this book will be of value to professionals and practitioners working in the field of software engineering.
Dans le cadre des réflexions sur le paysage français, l'État français a demandé à trois personnalités étrangères de porter un «regard neuf, extérieur sur les paysages français contemporains». Ces trois experts, un ingénieur aménageur japonais, un urbaniste néerlandais et un historien des jardins anglo-américain, ont voyagé en France pendant quinze jours selon l'itinéraire de leur choix; les trois rapports issus de ces voyages font la matière du présent volume.
Sexual selection is recognized as being responsible for some of the most extravagant morphologies and behaviors in the natural world, as well as a driver of some of the most rapid evolution. While Charles Darwin's theory is now a fundamental component of modern evolutionary biology, the impact of genotype-by-environment interactions on sexual selection has thus far received little attention. This book represents the first comprehensive analysis of the role genotype-by-environment interactions play in sexual selection and the potential implications that they have for the evolutionary process. The Editors have identified 13 topics that currently define the field and shed light on the impacts of these interactions on sexual selection. This includes key topics, such as resolving the lek paradox and how genotype-by-environmental interactions can compromise the honesty of sexual signals. The volume also outlines key questions that remain unanswered and provides a comprehensive guide to analyzing genotype-by-environment interactions. The mix of theory, empirical studies, and practical instructions from world leading experts make this book a particularly potent and definitive guide on the topic. It will be of interest to evolutionary biologists, spanning from genomicists to behaviorists. "This is a very timely book, covering a topic that should change the way we think about sexual selection. The contributors are all leaders and the topics should provide guidance to many PhD projects in the years to come. GEI is increasingly shown to be important, and it seems likely that it is critical in species where sexual selection is operating. This book is likely to help revitalize the study of sexual selection." Professor Allen Moore, The University of Georgia "GEIs fascinate evolutionary biologists, but the unique consequences for sexually selected traits have been neglected - until now. This multi-authored book comprehensively explains key theoretical concepts, handles practical `how to' issues and uses classic case studies to illustrate the value of studying GEIs. It is a must read for everyone interested in sexual selection." Professor Michael Jennions, The Australian National University
Provides a broad snapshot of recent findings showing how the environment and genes influence behavior The great debate of nature versus nurture rages on - but our understanding of the genetic basis of many behaviors has expanded over the last decade, and there is now very good evidence showing that seemingly complex behaviours can have relatively simple genetic underpinnings, but also that most behaviours have very complicated genetic and environmental architecture. Studies have also clearly shown that behaviors, and other traits, are influenced not just by genes and the environment, but also by the statistical interaction between the two. This book aims to end the nature versus nurture argument by showing that behaviors are nature and nurture and the interaction between the two, and by illustrating how single genes can explain some of the variation in behaviors even when they are seemingly complex. Genes and Behaviour: Beyond Nature-Nurture puts to rest the nature versus nurture dichotomy, providing an up-to-date synopsis of where we are, how far we've come and where we are headed. It considers the effects of a dual-inheritance of genes and culture, and genes and social environment, and highlights how indirect genetic effects can affect the evolution of behavior. It also examines the effect of non-self genes on the behavior of hosts, shines a light on the nature and nurturing of animal minds and invites us to embrace all the complexity nature and nurture generates, and more. Explores exciting new findings about behavior and where we go from here Features contributions by top scholars of the subject Seeks to end the nature versus nurture debate forever Genes and Behaviour: Beyond Nature-Nurture is a unique, and eye-opening read that will appeal to Ph.D. Students, post-doctoral fellows, and researchers in evolution and behavior. Additionally, the book will also be of interest to geneticists, sociologists and philosophers.
Warrior is the powerful true story of a British soldier's heroism during the Iraq War that reveals how he was ruthlessly sacrificed by the Establishment. Captain Tam Henderson was adopted as a baby in Glasgow. His family moved to England and he grew up on a violent council estate in Birmingham. At 16, he chose to join the famous Black Watch regiment. In a career spanning 23 years, he rose through the ranks and was deployed to conflicts in Northern Ireland, the Balkans and the Middle East.During the 2003 invasion of Iraq, Tam was in the thick of ferocious fighting and, amidst Basra's chaos, he set up camp for the 200 men of Charlie Company, who were put in charge of the city's most volatile districts. Having fought to recover the body of one of his men killed in action, Tam was horrified when the chain gun on his Warrior tank malfunctioned, suddenly firing of its own accord and seriously injuring a comrade. He was told to take the rap but refused, insisting that the dangerous fault on the gun needed fixing. He was convicted by a kangaroo court at Saddam's palace and sent home in disgrace. But Tam fought back and embarked upon the biggest battle of his life - against the Ministry of Defence and international arms companies.Pacy and starkly authentic, Warrior takes the reader on an exhilarating journey that is by turns horrific, humorous and poignantly reflective.
La nature sauvage, que les anciens jugeaient horrible et tentaient de domestiquer par places, et que les modernes exaltent pour compenser le progressif bétonnage des sites, a toujours eu quelque chose d'abstrait et de mythique. Si elle existe comme concept, il est impossible de l'atteindre dans la réalité sans la transformer en spectacle. Entre elle et nous s'interpose au moins un regard, c'est-à-dire un principe d'organisation, la possibilité de comprendre, de décrire et de représenter. Même la forêt primaire d'Amazonie, vue d'avion, devient un monument paysager. Que dire alors de la forêt de Fontainebleau que nous parcourons en tous sens ! L'art du jardin - en particulier les paysages européens du XVIIIe et du XIXe siècles - relève ainsi d'une charmante ambiguïté : il faut décrire la représentation figurée comme si elle était nature et la nature comme si elle était représentation figurée ; il faut que la surprise naisse d'un ordre prévisible à peine perturbé, que l'émotion sensorielle vienne d'une éducation qu'on oublie. À travers les deux très belles conférences prononcées en mars 1994 par John Dixon Hunt, le Collège de France a voulu faire mieux connaître au public français l'intérêt de la réflexion historique sur les jardins et l'architecture paysagère, discipline au confluent de plusieurs domaines : ceux de l'urbanisme et de l'architecture, de la géographie et de l'écologie, de la peinture et de la littérature, de la sociologie et de la philosophie de la représentation, des ères culturelles et de l'histoire enfin, puisqu'il existe autant de paysages que de grandes civilisations et d'époques. Professeur à l'université de Pennsylvanie, John Dixon Hunt a notamment dirigé l'Institut d'architecture paysagère de Dumbarton Oaks, à Washington. Il est l'auteur de plusieurs ouvrages de référence sur l'art des jardins, dont The Figure in the Landscape (1989), d'une biographie de John Ruskin et d'une étude sur les préraphaélites. Il dirige depuis sa création, en 1980, la revue internationale Journal of Garden History.
