The Dynamics of Agricultural Change: The Historical Experience (Routledge Library Editions: Agriculture #10)
by David GriggFirst published in 1982. Until the nineteenth-century the history of agriculture was the history of mankind but it has not perhaps received the wide attention that this importance justifies. In this study, the author reviews for the student of agricultural history successive attempts to describe and explain agricultural changes that are not specific to a limited area or a particular time. In a sense The Dynamics of Agricultural Change is a systematic historical geography of agriculture. Some of the models the author explores have been developed within agricultural history; some, drawn from other disciplines, can be applied fruitfully to it. What is the relationship between population growth and agricultural development? Between environmental changes and those in agriculture? What was the effect of the industrial revolution? And has there been an agricultural revolution? This book suggests to university students of economic history, historical geography and agriculture, a number of stimulating ways of interpreting and reinterpreting agricultural history.
The Dynamics of Cities: Ecological Determinism, Dualism and Chaos
by Dimitrios DendrinosDimitrios Dendrinos, an expert in the application of non-linear dynamics and chaos theory to the subject of urban and regional dynamics, focuses here on fundamental issues in population growth and decline. He approaches the topic of urban growth and decline within a global system perspective, viewing the rise and fall of cities, industries and nations as the result of global interdependencies which lead to unstable dynamics and widespread dualisms. Professor Dendrinos provides valuable insights into the evolution of human settlements and considers the possible futures open to the giant cities of the world.
Dynamics of Climate Change and Water Resources of Northwestern Himalaya
by Rajesh Joshi Kireet Kumar Lok Man S. PalniThis book is about the Himalayan ranges as a source of fresh water supply and a perennial store house of ice, snow and permafrost as well as a vast repository of rich biodiversity, in the light of climate change. Special attention is given to the dynamics of snow and glaciers in the northwestern Himalayas, assessment of climate change patterns, and the consequences of changes and flow regime in order to understand the behaviour of climate change in the northwestern Himalayas. The outcome of melting glaciers are pro-glacial lakes. Their increasing size and potential danger of outbursts requires systematic study, particularly where there is the risk of impact on life and property. Furthermore, the changing trend of the hydrological cycle on a regional or local scale is another area of research which calls for the attention of geoscientists. To date there is a scarcity of reliable data meaning that a concerted effort is still required by all parties.

The Dynamics of Disaster
by Susan W. Kieffer"If you are an amateur weather geek, disaster wonk, or budding student of earth sciences, you will want to read this book."--Seattle Times In 2011, there were fourteen natural calamities that each destroyed over a billion dollars' worth of property in the United States alone. In 2012, Hurricane Sandy ravaged the East Coast and major earthquakes struck in Italy, the Philippines, Iran, and Afghanistan. In the first half of 2013, the awful drumbeat continued--a monster supertornado struck Moore, Oklahoma; a powerful earthquake shook Sichuan, China; a cyclone ravaged Queensland, Australia; massive floods inundated Jakarta, Indonesia; and the largest wildfire ever engulfed a large part of Colorado. Despite these events, we still behave as if natural disasters are outliers. Why else would we continue to build new communities near active volcanoes, on tectonically active faults, on flood plains, and in areas routinely lashed by vicious storms? A famous historian once observed that "civilization exists by geologic consent, subject to change without notice." In the pages of this unique book, leading geologist Susan W. Kieffer provides a primer on most types of natural disasters: earthquakes, tsunamis, volcanoes, landslides, hurricanes, cyclones, and tornadoes. By taking us behind the scenes of the underlying geology that causes them, she shows why natural disasters are more common than we realize, and that their impact on us will increase as our growing population crowds us into ever more vulnerable areas. Kieffer describes how natural disasters result from "changes in state" in a geologic system, much as when water turns to steam. By understanding what causes these changes of state, we can begin to understand the dynamics of natural disasters. In the book's concluding chapter, Kieffer outlines how we might better prepare for, and in some cases prevent, future disasters. She also calls for the creation of an organization, something akin to the Centers for Disease Control and Prevention but focused on pending natural disasters.
Dynamics of Economic Spaces in the Global Knowledge-based Economy: Theory and East Asian Cases (Regions and Cities)
by Sam Ock ParkThis book addresses how economic spaces dynamically change within the context of the global knowledge-based economy. Specifically, it centers the discussion on integrated views of understanding and conceptualizing dynamic changes of global economy under the global megatrends of globalization, knowledge-based economy, information society, service world, climate change, and population aging. Focusing on East Asia, especially on Korea, it deals with case studies regarding the processes and patterns of these global dynamics, looking at economic spaces of various spatial scales and types of economic actors. This book develops a theoretical model for understanding and analysing the dynamics of economic spaces that are being reshaped within the larger global economy. It also emphasizes the analysis of empirical studies at the level of firm, region, and state by considering an evolutionary perspective over time. In developing its theoretical framework, this book examines regional resilience, intangible assets, service innovation, path dependence, and other notions related to the evolution of economic spaces, and incorporates these elements into real-world case studies. The integrated theoretical framework examined here contributes a new perspective on spatial disparities in the global economy. An integral model of service innovation; the integration of path dependence and regional resilience; the interaction between firm and region for the accumulation of intangible assets; and the roles of governments and global firms: these are all essential to understanding the dynamics of economic spaces in East Asia. The theoretical model and case studies in this book suggest policy implications for developing countries, especially in the Asian and African regions, with regard to regional development and innovation policies.

Dynamics of Extremal Black Holes (SpringerBriefs in Mathematical Physics #33)
by Stefanos AretakisThis Brief presents in a self-contained, non-technical and illustrative fashion the state-of-the-art results and techniques for the dynamics of extremal black holes. Extremal black holes are, roughly speaking, either maximally rotating or maximally charged. Astronomical observations suggest that near-extremal (stellar or supermassive) black holes are ubiquitous in the universe. The book presents various recently discovered characteristic phenomena (such as the horizon instability) that have enhanced our understanding of the dynamics of extremal black holes. The topics should be of interest to pure mathematicians, theoretical physicists and astronomers. This book provides common ground for communication between these scientific communities.

The Dynamics of Heritage: History, Memory and the Highland Clearances (Heritage, Culture and Identity)
by Laurence GouriévidisThere has been much academic interest in the role of museums as places where understanding of the past is shaped and legitimised for a wide and increasingly diverse public. This book focuses on the museum representations of the Highland Clearances - a much neglected aspect of one of the most disputed and politically-charged issues in modern Scottish history. Drawing together a range of inter-disciplinary themes and notions, it considers the cultural legacy of the period, brings to light the socially and historically conditioned meanings and values encapsulated in museum narratives of the Clearances, and shows the significance of collective memory in the negotiations inherent in heritage work. Examining both national and local museums in Scotland and concluding with comparisons with Australian museums of migration, Dynamics of Heritage contributes to our understanding of the processes of heritage construction, and its relationship to issues of memory and other modes of engagement with the past.
The Dynamics of Human Development: A Partial Mobility Perspective
by Atanu Sengupta Abhijit GhoshThis book studies the dynamic aspects of the Human Development Index (HDI) through a partial mobility perspective. It offers a new axiomatic structure and a set of mobility indices to discuss partial trends and interrogate the human development status at the subgroup and subregional levels. While traditional human development theories are primarily concerned with static distributions corresponding to a point in time, this book looks at an oft-neglected side of HDI and focuses on relative changes in human development that may not be captured by the absolutist framework. In addition, the authors also introduce the concepts of jump and fractional mobility which aid in tracking the development and stagnation among various groups within a population. This work breaks fresh ground in the study of human development. It will be of great interest to scholars and researchers of economics, development economics, political economy, and development practitioners.
Dynamics of Hydrocarbon Migration: Quantitative Dynamics Studies and Applications
by Xiaorong Luo Likuan Zhang Yuhong Lei Wan YangThis book presents the authors' research findings on the dynamics of oil migration, research methodologies, insights and applications in petroliferous basins. It studies the behaviors of oil migration in porous media through physical experiments and numerical simulations, explores the mechanism of oil migration and effects of migration process, and then establishes a migration modeling method by coupling the source, driving forces and carriers. The new method can be used to estimate the amount of migrated hydrocarbons and then predict the location of possible hydrocarbon accumulations in different parts of a basin. This approach is useful for resources assessment and prediction of the distribution of hydrocarbon accumulations. An example utilizing this methodology is presented to study the dynamics of migration and accumulation processes in the southern slope of Dongying Depression in Bohai Bay Basin in China. The book appeals to scientists and professionals working on petroleum prospecting as well as faculty and students in petroleum geology.
The Dynamics of Iranian Borders: Issues of Contention
by Mansoureh Ebrahimi Masoumeh Rad Goudarzi Kamaruzaman YusoffThis book is on Iran’s geopolitical importance representing a continuum of international competition for political gains and economic benefit, due to the country's unique geographical location that has always been a cause of contention. Iran’s massive boarders and evolving political weakness, along with influences from the kings of Qajar that maintained and strengthened Great Britain’s hegemony in the region, were major factors affecting ongoing regional conflicts. Additional roles played by other world powers such as France, Russia and the United States are also noted. Conflicts, unrest and regional wars were all consequences arising from power struggles that led to treaties and international agreements between Iran, Britain and Russia that caused the eventual loss of traditional Iranian territories. Hence, extrinsic impositions on Iran are the subject of this study as authors examine the turbulent climate that altered Iranian borders during the Qajar Dynasty.

Dynamics of Mechanical Systems with Non-Ideal Excitation
by Livija Cveticanin Miodrag Zukovic Jose Manoel BalthazarIn this book the dynamics of the non-ideal oscillatory system, in which the excitation is influenced by the response of the oscillator, is presented. Linear and nonlinear oscillators with one or more degrees of freedom interacting with one or more energy sources are treated. This concerns for example oscillating systems excited by a deformed elastic connection, systems excited by an unbalanced rotating mass, systems of parametrically excited oscillator and an energy source, frictionally self-excited oscillator and an energy source, energy harvesting system, portal frame – non-ideal source system, non-ideal rotor system, planar mechanism – non-ideal source interaction. For the systems the regular and irregular motions are tested. The effect of self-synchronization, chaos and methods for suppressing chaos in non-ideal systems are considered. In the book various types of motion control are suggested. The most important property of the non-ideal system connected with the jump-like transition from a resonant state to a non-resonant one is discussed. The so called ‘Sommerfeld effect’, resonant unstable state and jumping of the system into a new stable state of motion above the resonant region is explained. A mathematical model of the system is solved analytically and numerically. Approximate analytical solving procedures are developed. Besides, simulation of the motion of the non-ideal system is presented. The obtained results are compared with those for the ideal case. A significant difference is evident. The book aims to present the established results and to expand the literature in non-ideal vibrating systems. A further intention of the book is to give predictions of the effects for a system where the interaction between an oscillator and the energy source exist. The book is targeted at engineers and technicians dealing with the problem of source-machine system, but is also written for PhD students and researchers interested in non-linear and non-ideal problems.
The Dynamics of Migration, Health and Livelihoods: INDEPTH Network Perspectives
by Kubaje AdazuUsing INDEPTH's multi-site network to provide new demographic insights into population variables, this book provides a new perspective on migration, health and livelihood's interaction over time. The book starts with providing a conceptual and methodological framework to inform the epidemiological studies that are clustered into two themes, showing the dynamics of migration with either household livelihoods or individual health outcomes. The findings demonstrate the important cross-national regularities in human migration. The contributed chapters also exemplify the fact that the impacts of migration can be either positive or negative for sending and/or receiving communities, depending on the issues at hand and the type of migration under consideration.

Dynamics of the Earth
by S. V. Ferronsky V. I. FerronskyIn their search for solutions to problems concerning the dynamics of the Earth as a self-gravitating body, the authors have applied the fundamentals found in their book "Jacobi Dynamics" (1987, Reidel). First, satellite observations have shown that the Earth does not remain in hydrostatic equilibrium, which forms the physical basis of modern geodynamics. Secondly, satellite data have established a relationship between the planet's polar moment of inertia and the potential of the Earth's outer force field, which proves the most basic point of Jacobi dynamics. This allowed the authors to revise their derivation of the classical virial theorem, introducing the concept of a volumetric force and volumetric moment, and so to obtain a generalized virial theorem in the form of Jacobi's equation. The main dynamical effects are: the kinetic energy of oscillation of the interacting particles, which explains the physical meaning and nature of gravitational forces; separation of shells of a self-gravitating body with respect to its mass density; differences in angular velocities of the shell's rotation; continuity in variance of the potential of the outer gravitational force field, together with reductions in the envelope of the interacting masses (volumetric center of gravity); the nature of Earth, Moon and satellite precession; the nature and generating mechanism of the planet's electromagnetic field; the common nature of gravitational and electromagnetic energy, and other related issues. The work is a logical continuation of the book "Jacobi Dynamics" and is intended for researchers, teachers and students engaged in theoretical and experimental research in various branches of astronomy, geophysics, planetology and cosmogony, and for students of celestial, statistical, quantum and relativistic mechanics and hydrodynamics.
