Learning from clusters : A critical assessment from an economic-geographical perspective

Edited volumes run the danger of being a hotchpotch of contributions on a wide variety of topics. Here, we have explicitly focused on a central theme in contemporary economic geography and regional science, namely the relationship between learning, innovation and clustering. Internationally renowned scientists made both theoretical and empirical contributions to this volume. We think this book constitutes a broad palette of contemporary thinking and research on the relationship between spatial concentration and innovation and hope it will play a significant role in future debates on this issue.

Learning About Particles - 50 Privileged Years

Embedded in an autobiographic framework, this book retraces vividly and in some depth the golden years of particle physics as witnessed by one of the scientists who made seminal contributions to the understanding of what is now known as the Standard Model of particle physics. Well beyond a survey of interest to historians of sciences and researchers in the field, this book is a must for all students and young researchers who have learned about the theoretical and experimental facts that make up the standard model through modern textbooks only. It will provide the interested reader with a first hand account and deeper understanding of the multilayered and sinuous development that finally led to the present architecture of this theory.

Laws of Nature

The book is concerned with the laws of nature and in particular with the laws of physics. The authors discuss three important questions: First, whether the observed regularities are based on strict "laws of nature" that hold rigorously and without any exception. Second, what we call a "law of nature" is studied by comparing this concept with invariance principles, causality principles, teleological principles and means of predicting future events. Finally, on the basis of these investigations the authors treat the ambitious and intricate third question, why the laws of nature hold. Are there rational reasons for this largely unexplained phenomenon? This book addresses students as well as researchers. It will be an excellent reference for those interested in the philosophical foundations of the natural sciences.

Lattice Hadron Physics

This series of lectures draws upon the developments made in recent years in implementing chirality on the lattice via the overlap formalism. These developments exploit chiral effective field theory in order to extrapolate lattice results to physical quark masses, new forms of improving operators to remove lattice artefacts, analytical studies of finite volume effects in hadronic observables, and state-of-the-art lattice calculations of excited resonances. This volume is designed to assist those outside the field who want quickly to becoming literate in these topics. So it is intended for graduate students and experienced researchers in other areas of hadronic physics to provide the background through which they can appreciate, if not become active in, contemporary lattice gauge theory and its applications to hadronic phenomena.

Lattice Boltzmann Modeling : An Introduction for Geoscientists and Engineers

Lattice Boltzmann models have a remarkable ability to simulate single- and multi-phase fluids and transport processes within them. A rich variety of behaviors, including higher Reynolds numbers flows, phase separation, evaporation, condensation, cavitation, buoyancy, and interactions with surfaces can readily be simulated. This book provides a basic introduction that emphasizes intuition and simplistic conceptualization of processes. It avoids the more difficult mathematics that underlies LB models. The model is viewed from a particle perspective where collisions, streaming, and particle-particle/particle-surface interactions constitute the entire conceptual framework. Beginners and those with more interest in model application than detailed mathematical foundations will find this a powerful "quick start" guide. Example simulations, exercises, and computer codes are included. Working code is provided on the Internet.

Lattice : Multivariate Data Visualization with R

R is rapidly growing in popularity as the environment of choice for data analysis and graphics both in academia and industry. Lattice brings the proven design of Trellis graphics (originally developed for S by William S. Cleveland and colleagues at Bell Labs) to R, considerably expanding its capabilities in the process. Lattice is a powerful and elegant high level data visualization system that is sufficient for most everyday graphics needs, yet flexible enough to be easily extended to handle demands of cutting edge research. Written by the author of the lattice system, this book describes it in considerable depth, beginning with the essentials and systematically delving into specific low levels details as necessary. No prior experience with lattice is required to read the book, although basic familiarity with R is assumed.

Latinas/os in the United States : Changing the Face of América

This book also addresses important theoretical and methodological issues related to the study of Latinas/os and presents in-depth analyses (both quantitative and qualitative) of substantive issues relevant to this population, including migration, demographic patterns and processes, education, health, citizenship, political participation, religion, gender and sex roles, literary and cultural production, and the media. The authors seek to educate and increase awareness of the diversity that exists among the Latina/o population, and to carefully examine the social, economic, demographic, cultural, and political impacts and contributions that this growing population has had in the United States. The edited volume presents a holistic and multidisciplinary perspective of this group, and it critically documents how Latinas and Latinos have changed and will continue to change the face of América.

Landscapes Under Pressure : Theory and Practice of Cultural Heritage Research and Preservation

This book investigates the newly emerging scope of interests and project agendas to investigate and preserve cultural landscapes. It presents the historic, archaeological, ethnographic, and environmental traditions of cultural landscape study and the attempts to reconstruct and analyze the complex processes of cultural changes through prehistoric and historic times.The "guiding light" of the book is that the fullest understanding of a cultural landscape will materialize through interdisciplinary cooperation, which should involve an ecological approach with historical ecology as the guiding tool, applied archaeology, and environmental planning.

Landscapes of Mars : A Visual Tour

Landscapes of Mars is essentially a picture book that provides a visual tour of Mars. All the major regions and topographical features will be shown and supplemented with chapter introductions and extended captions. In a way, think of it as a visual tourist guide. Other topics covered are Martian uplands on the order of the elevation of Mt. Everest, Giant volcanoes and a rift system, the Grand Canyon of Mars, craters and the absence of craters over large regions (erosion), and wind shadows around craters, sand dunes, and dust devils.

Landscape Analysis and Visualisation : Spatial Models for Natural Resource Management and Planning

This book presents a collection and synthesis of many of these perspectives — perhaps it could only be produced in a land urb- ised in the tiniest of pockets, and yet so daunting with respect to the way non-populated landscapes dwarf its cities. Many travel to Australia to its cities and never see the landscapes — but it is these that give the country its power and imagery. It is the landscapes that so impress on us the need to consider how our intervention, through activities ranging from resource exploitation and settled agriculture to climate change, poses one of the greatest crises facing the modern world. In this sense, Australia and its landscape provide a mirror through which we can glimpse the extent to which our intervention in the world threatens its very existence.

Lake Victoria : Ecology, Resources, Environment

Recently, there has been, and continues to be, a tremendous interest on Lake Victoria and its environs, both locally and internationally. A casual browsing on the Internet indicates that the entries on the Lake have been rising phenomenally. At the same time, the issues discussed are as diverse as they are varied in their treatment of the subject, both in terms of depth and comprehensiveness. The information on Lake Victoria and its environ is scattered, isolated, and sometimes confusing even though documentation on the subject are available. Despite this situation, the fact remains that various people (e. g. , secondary and universitystudents,researchers,practitioners,etc. ,)wouldliketoaccess and know more about the Lake and its environs. Aware of the existing information gap about this world’s second largest fresh water Lake, this book is intended to provide readers with up-to-date information pertaining the Lake. The book gives an in-depth coverage of environmental issues, - source endowment, poverty amidst plenty, development opportunities, challenges and other related issues facing the Lake and its environs. It aims at providing information on the above variables, which hopefully will address the needs of various users.

K-Theory : An Introduction

From the Preface: K-theory was introduced by A. Grothendieck in his formulation of the Riemann- Roch theorem. For each projective algebraic variety, Grothendieck constructed a group from the category of coherent algebraic sheaves, and showed that it had many nice properties. Atiyah and Hirzebruch con­sidered a topological analog defined for any compact space X, a group K{X) constructed from the category of vector bundles on X. It is this ''topological K-theory" that this book will study. Topological K-theory has become an important tool in topology. Using K- theory, Adams and Atiyah were able to give a simple proof that the only spheres which can be provided with H-space structures are S1, S3 and S7. Moreover, it is possible to derive a substantial part of stable homotopy theory from K-theory.

Kristian Birkeland : The First Space Scientist

PREFACEThisscientific biography of Kristian Birkeland (1867–1917) was written to bring the story ofa Norwegian national hero to the attention ofthe English-speaking world. Birkeland’sheroic stature was established not on a field of military battle,but in the bitter cold of the Artic wilderness ashe sought to answer basic questions abouthow the Sun controlled northern lights andmag-netic storms. He was also afather of Norsk Hydro one ofNorway’s largest industries. Birkel and died before reaching the age of 50.Because Birkel and never kept adiary, documented information about his family and private life is sparse. Before he died, Olaf Devik, the last of Birke-ffland’s close friends, gave along interview and graciously transferred his personal archive to A.E. Birkeland’s 82 scientific papers and three book-length publications map the progress of his investigations. addressed this book questions that had vexed European scientists for centuries. Why do the northern lights appear overhead when the Earth’s magnetic field is disturbed? How are magnetic storms connected to disturbances on the Sun? To answer these questions Birkeland interpreted his advance laboratory simulations and daring campaigns in the Arctic wilderness in the light of Maxwell’s newly discovered laws of electricity and magnetism. Birkeland’s ideas were dismissed for decades, only to be vindicated when satellites could fly above the Earth’s atmosphere.

Kinetics of Water-Rock Interaction

Systems at the surface of the Earth are continually responding to energy inputs derived from solar radiation or from the radiogenic heat in the interior. These energy inputs drive plate movements and erosion, exposing metastable mineral phases at the Earth’s surface. In addition, these energy fluxes are harvested and transformed by living organisms. As long as these processes persist, chemical disequilibrium at the Earth’s surface will be perpetuated. Chemical disequilibrium is also driven by human activities related to production of food, extraction of water and energy resources, and burial of wastes. To understand how the surface of the Earth will change over time, we must understand the rates at which reactions occur and the chemical feedbacks that relate these reactions across extreme temporal and spatial scales. This book addresses fundamental and applied questions concerning the rates of water-rock interactions driven by tectonic, climatic, and anthropogenic forcings.

John Dee : Interdisciplinary Studies in English Renaissance Thought

This volume records the diversity of scholarly approaches to John Dee which have emerged since the synthetic accounts of I. R. F. Calder, Frances Yates and Peter French. If these approaches have not succeeded in resolving the problematic multiplicity of Dee’s activities, they will at least deepen our understanding of specific and local areas of his intellectual life, and render them more historiographically legible.

Japan’s Arduous Rejuvenation as a Global Power : Democratic Resilience and the US-China Challenge

This book assesses the profound impact of Japan’s aspirations to become a great power on Japanese security, democracy and foreign relations. Rather than viewing the process of normalization and rejuvenation as two decades of remilitarization in face of rapidly changing strategic environment and domestic political circumstances, this volume contextualizes Japan’s contemporary international relations against the longer grain of Japanese historical interactions.It also submits that an improvement in Japan-China relations would enhance rather than detract Japan-US relations and that Tokyo will find that her new found automony in the US-Japan alliance would not only accord her more political respect and strategic latitude, but also allow her to ameliorate the excesses of American foreign policy adventurism, paving for her to become a truly normal great power.
