Drawing on Nietzsche's challenge to the western tradition, this book is a theological exploration of cruelty in its personal, communal and institutional encounters in human life. Cruelty undermines care, trust, respect and justice, and its study opens a window into the theological possibility of reconciliation today.
This book presents and describes an innovative method to simulate the growth of natural fractural networks in different geological environments, based on their geological history and fundamental geomechanical principles. The book develops techniques to simulate the growth and interaction of large populations of layer-bound fracture directly, based on linear elastic fracture mechanics and subcritical propagation theory. It demonstrates how to use these techniques to model the nucleation, propagation and interaction of layer-bound fractures in different orientations around large scale geological structures, based on the geological history of the structures. It also explains how to use these techniques to build more accurate discrete fracture network (DFN) models at a reasonable computational cost. These models can explain many of the properties of natural fracture networks observed in outcrops, using actual outcrop examples. Finally, the book demonstrates how it can be incorporated into flow modelling workflows using subsurface examples from the hydrocarbon and geothermal industries. Modelling the Evolution of Natural Fracture Networks will be of interest to anyone curious about understanding and predicting the evolution of complex natural fracture networks across large geological structures. It will be helpful to those modelling fluid flow through fractures, or the geomechanical impact of fracture networks, in the hydrocarbon, geothermal, CO2 sequestration, groundwater and engineering industries.
Today, the Bay Area is home to the most successful knowledge economy in America, while Los Angeles has fallen progressively further behind its neighbor to the north and a number of other American metropolises. Yet, in 1970, experts would have predicted that L.A. would outpace San Francisco in population, income, economic power, and influence. The usual factors used to explain urban growth—luck, immigration, local economic policies, and the pool of skilled labor—do not account for the contrast between the two cities and their fates. So what does? The Rise and Fall of Urban Economies challenges many of the conventional notions about economic development and sheds new light on its workings. The authors argue that it is essential to understand the interactions of three major components—economic specialization, human capital formation, and institutional factors—to determine how well a regional economy will cope with new opportunities and challenges. Drawing on economics, sociology, political science, and geography, they argue that the economic development of metropolitan regions hinges on previously underexplored capacities for organizational change in firms, networks of people, and networks of leaders. By studying San Francisco and Los Angeles in unprecedented levels of depth, this book extracts lessons for the field of economic development studies and urban regions around the world.
