Book excerpt: Taking the instability of all identities as its point of departure, this collection of essays probes the enigmas of identity politics. How does 'identitarian' politics, trying to homogenize identities around some cultural or ethnic name, deal with unstable and diverse identities? And what are the kinds of identity formations that resist identity-based projects? Drawing from theoretical perspectives on communal polarization and its relation to early nationalism, the author examines a range of seemingly dissimilar subjects, such as the teaching of Keats in a Delhi college, the Indian novel in the English language, nineteenth-century Banglasahitya, inter-community love, communalism, Tagore and globalization, and inter-disciplinarity. Some of the essays in this book are especially concerned with the recent decades that have witnessed the rise of Hindutva, and which have also marked the author's own growth from a student of English Literature at Delhi University to his later interest and scholarship in history and politics. Pradip Datta begins with his reading of Keats, the quintessential Romantic poet, under the tutelage of a teacher of English with a vernacular background, at a time that witnessed the capitalist expansion of the middle class as well as the spread of the Ram Janmabhoomi movement across the cities and towns of India. His interest in plotting the coordinates of heterogeneity and interrogating identity formations led him to travel to Ayodhya in the early 1990s and interact with kar sevaks there.This book is therefore a part of the author's ongoing attempt at examining how literary and politico-cultural representations of identities can reinforce rigid boundaries. Juxtaposing these with knowledge systems and their respective methods, Pradip Datta argues in favor of practices and spaces that facilitate exchange and reciprocity among a range of disciplines. By proposing the idea of a disciplinary 'commons', he offers the pedagogic as a model for recognizing and validating the heterogeneous elements in the formation of our identities.

This book was released on 2011-07-14 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the solid materials we use in everyday life, from plastics to cosmetic gels exist under a non-crystalline, amorphous form: they are glasses. Yet, we are still seeking a fundamental explanation as to what glasses really are and to why they form. In this book, we survey the most recent theoretical and experimental research dealing with glassy physics, from molecular to colloidal glasses and granular media. Leading experts in this field present broad and original perspectives on one of the deepest mysteries of condensed matter physics, with an emphasis on the key role played by heterogeneities in the dynamics of glassiness.

Download or read book Local Commons and Global Interdependence written by Robert O Keohane and published by SAGE. This book was released on 1994-11-15 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers a synthesis of what is known about very large and very small common-pool resources. Individuals using commons at the global or local level may find themselves in a similar situation. At an international level, states cannot appeal to authoritative hierarchies to enforce agreements they make to cooperate with one another. In some small-scale settings, participants may be just as helpless in calling on distant public officials to monitor and enforce their agreements. Scholars have independently discovered self-organizing regimes which rely on implicit or explicit principles, norms, rules and procedures rather than the command and control of a central authority. The contributors discuss the possibilities and dangers of scaling up and scaling down. They explore the impact of the number of actors and the degree of heterogeneity among actors on the likelihood of cooperative behaviour.

Book excerpt: In this work a known philosopher offers an analysis of the hidden assumptions that lie at the heart of contemporary social ideology. Robert John Ackermann argues that all social life is intrinsically heterogeneous and that such homogeneous constructs as race, gender, class, nation and state are necessarily artificial. In the course of his inquiry, he discusses what we mean when we invoke these terms and explores the intellectual implications and concrete consequences of their everyday use.

Available in PDF, EPUB and Kindle. Book excerpt: This book highlights and discusses recent developments that have contributed to an improved understanding of observed mantle heterogeneities and their relation to the thermo-chemical state of Earth's mantle, which ultimately holds the key to unlocking the secrets of the evolution of our planet. This series of topical reviews and original contributions address 4 themes. Theme 1 covers topics in geophysics, including global and regional seismic tomography, electrical conductivity and seismic imaging of mantle discontinuities and heterogeneities in the upper mantle, transition zone and lower mantle. Theme 2 addresses geochemical views of the mantle including lithospheric evolution from analysis of mantle xenoliths, composition of the deep Earth and the effect of water on subduction-zone processes. Theme 3 discusses geodynamical perspectives on the global thermo-chemical structure of the deep mantle. Theme 4 covers application of mineral physics data and phase equilibrium computations to infer the regional-scale thermo-chemical structure of the mantle.
Download or read book The Transnationalized Social Question written by Thomas Faist and published by Oxford University Press. This book was released on 2018-12-13 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: The social question is back. Yet today's social question is not primarily between labour and capital, as it was in the nineteenth century and throughout much of the twentieth. The contemporary social question is located at the interstices between the global South and the global North. It finds its expression in movements of people, seeking a better life or fleeing unsustainable social, political, economic, and ecological conditions. It is transnationalized not only because migrants and their significant others entertain ties across the borders of national states, staying in touch with family and friends, receiving or sending financial remittances in transnational social spaces. Also of importance are cross—border recruitment schemes for workers and the cross-border diffusion of norms appealed to in the case of migration—for example, the social right to decent work as a human right. Moreover, migration can become an issue of inclusion or exclusion in fields important to life chances in the emigration, transit, or immigration states—a transnationalization of national states. And, as in the nineteenth century, political conflicts arise, constituting the social question as a public concern. In earlier periods class differences dominated conflicts. While class has always been criss-crossed by manifold heterogeneities, not least of all cultural ones around ethnicity, religion, and language, it is these latter heterogeneities that have sharpened in situations of immigration and emigration over the past decades. Casting a wide net in terms of conceptual and empirical scope, this book tackles both the social structure and the politics of social inequalities. It sets a comprehensive agenda for research which also includes the public role of social scientists in dealing with the transnationalized social question.
Download or read book Numerical Simulation of Pore scale Heterogeneity and Its Effects on Elastic Electrical and Transport Properties written by Ratnanabha Sain and published by Stanford University. This book was released on 2010 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes numerical experiments quantifying the influence of pore-scale heterogeneities and their evolution on macroscopic elastic, electrical and transport properties of porous media. We design, implement and test a computational recipe to construct granular packs and consolidated microstructures replicating geological processes and to estimate the link between process-to-property trends. This computational recipe includes five constructors: a Granular Dynamics (GD) simulation, an Event Driven Molecular Dynamics (EDMD) simulation and three computational diagenetic schemes; and four property estimators based on GD for elastic, finite-elements (FE) for elastic and electrical conductivity, and Lattice-Boltzmann method (LBM) for flow property simulations. Our implementation of GD simulation is capable of constructing realistic, frictional, jammed sphere packs under isotropic and uniaxial stress states. The link between microstructural properties in these packs, like porosity and coordination number (average number of contacts per grain), and stress states (due to compaction) is non-unique and depends on assemblage process and inter-granular friction. Stable jammed packs having similar internal stress and coordination number (CN) can exist at a range of porosities (38-42%) based on how fast they are assembled or compressed. Similarly, lower inter-grain friction during assemblage creates packs with higher coordination number and lower porosity at the same stress. Further, the heterogeneities in coordination number, spatial arrangement of contacts, the contact forces and internal stresses evolve with compaction non-linearly. These pore-scale heterogeneities impact effective elastic moduli, calculated by using infinitesimal perturbation method. Simulated stress-strain relationships and pressure-dependent elastic moduli for random granular packs show excellent match with laboratory experiments, unlike theoretical models based on Effective Medium Theory (EMT). We elaborately discuss the reasons why Effective Medium Theory (EMT) fails to correctly predict pressure-dependent elastic moduli, stress-strain relationships and stress-ratios (in uniaxial compaction) of granular packs or unconsolidated sediments. We specifically show that the unrealistic assumption of homogeneity in disordered packs and subsequent use of continuum elasticity-based homogeneous strain theory creates non-physical packs, which is why EMT fails. In the absence of a rigorous theory which can quantitatively account for heterogeneity in random granular packs, we propose relaxation corrections to amend EMT elastic moduli predictions. These pressure-dependent and compaction-dependent (isotropic or uniaxial) correction factors are rigorously estimated using GD simulation without non-physical approximations. Further, these correction factors heuristically represent the pressure-dependent heterogeneity and are also applicable for amending predictions of theoretical cementation models, which are conventionally used for granular packs. For predicting stress-ratios in uniaxial compaction scenario, we show the inappropriateness of linear elasticity-based equations, which use elastic constants only and do not account for dissipative losses like grain sliding. We further implement and test a computational recipe to construct consolidated microstructures based on different geological scenarios, like sorting, compaction, cementation types and cement materials. Our diagenetic trends of elastic, electrical and transport properties show excellent match with laboratory experiments on core plugs. This shows the feasibility of implementing a full-scale computational-rock-physics-based laboratory to construct and estimate properties based on geological processes. However, the elastic property estimator (FE simulation) shows limitations of finite resolution while computing elastic properties of unconsolidated sediments and fluid-saturated microstructures.
