Mechanisms

Author: Matthew G. Kirschenbaum
Publisher: MIT Press
ISBN: 9780262113113
Release Date: 2008-01
Genre: Social Science

In Mechanisms, Matthew Kirschenbaum examines new media and electronic writing against the textual and technological primitives that govern writing, inscription, and textual transmission in all media: erasure, variability, repeatability, and survivability. Mechanisms is the first book in its field to devote significant attention to storage--the hard drive in particular--arguing that understanding the affordances of storage devices is essential to understanding new media. Drawing a distinction between "forensic materiality" and "formal materiality," Kirschenbaum uses applied computer forensics techniques in his study of new media works. Just as the humanities discipline of textual studies examines books as physical objects and traces different variants of texts, computer forensics encourage us to perceive new media in terms of specific versions, platforms, systems, and devices. Kirschenbaum demonstrates these techniques in media-specific readings of three landmark works of new media and electronic literature, all from the formative era of personal computing: the interactive fiction game Mystery House, Michael Joyce's Afternoon: A Story, and William Gibson's electronic poem "Agrippa."

Mechanisms of Protease Action

Author: Laszlo Polgar
Publisher: CRC Press
ISBN: 0849369010
Release Date: 1989-01-31
Genre: Medical

A uniform treatment of the four protease groups and a discussion of the differences and similarities in their action is presented in this important new publication. Serine, cysteine, aspartate, and zinc proteases are systematically discussed by nomenclature, evolution, specificity and their regulatory role. The chemistry of the peptide bond, including the catalysis of ester and peptide hydrolyses, is explained. For each protease group the emphasis is placed on the structure and function. Kinetics, enzyme modifications, isotope effects, subzero temperature investigations, nuclear magnetic resonance measurements, X-ray diffraction data, binding of transition-state analogs, zymogen activation, and site-specific mutagenesis are combined to rationalize the action of proteases. Both natural and synthetic inhibitors are considered because of their importance in mechanistic studies and drug design.

Social Mechanisms

Author: Peter Hedström
Publisher: Cambridge University Press
ISBN: 0521596874
Release Date: 1998-01-13
Genre: Political Science

The advancement of social theory requires an analytical approach that systematically seeks to explicate the social mechanisms that generate and explain observed associations between events. These essays, written by prominent social scientists, advance criticisms of current trends in social theory and suggest alternative approaches. The mechanism approach calls attention to an intermediary level of analysis in between pure description and story-telling, on the one hand, and grand theorizing and universal social laws, on the other. For social theory to be of use for the working social scientist, it must attain a high level of precision and provide a toolbox from which middle range theories can be constructed.

Reduced Kinetic Mechanisms for Applications in Combustion Systems

Author: Norbert Peters
Publisher: Springer Science & Business Media
ISBN: 9783540563723
Release Date: 1993-01-22
Genre: Science

In general, combustion is a spatially three-dimensional, highly complex physi co-chemical process oftransient nature. Models are therefore needed that sim to such a degree that it becomes amenable plify a given combustion problem to theoretical or numerical analysis but that are not so restrictive as to distort the underlying physics or chemistry. In particular, in view of worldwide efforts to conserve energy and to control pollutant formation, models of combustion chemistry are needed that are sufficiently accurate to allow confident predic tions of flame structures. Reduced kinetic mechanisms, which are the topic of the present book, represent such combustion-chemistry models. Historically combustion chemistry was first described as a global one-step reaction in which fuel and oxidizer react to form a single product. Even when detailed mechanisms ofelementary reactions became available, empirical one step kinetic approximations were needed in order to make problems amenable to theoretical analysis. This situation began to change inthe early 1970s when computing facilities became more powerful and more widely available, thereby facilitating numerical analysis of relatively simple combustion problems, typi cally steady one-dimensional flames, with moderately detailed mechanisms of elementary reactions. However, even on the fastest and most powerful com puters available today, numerical simulations of, say, laminar, steady, three dimensional reacting flows with reasonably detailed and hence realistic ki netic mechanisms of elementary reactions are not possible.

The Mechanisms of Governance

Author: Oliver E. Williamson
Publisher: Oxford University Press
ISBN: 0199879567
Release Date: 1996-02-29
Genre: Business & Economics

This book brings together in one place the work of one of our most respected economic theorists, on a field in which he has played a large part in originating: the New Institutional Economics. Transaction cost economics, which studies the governance of contractual relations, is the branch of the New Institutional Economics with which Oliver Williamson is especially associated. Transaction cost economics takes issue with one of the fundamental building blocks in microeconomics: the theory of the firm. Whereas orthodox economics describes the firm in technological terms, as a production function, transaction cost economics describes the firm in organizational terms, as a governance structure. Alternative feasible forms of organization--firms, markets, hybrids, bureaus--are examined comparatively. The analytical action resides in the details of transactions and the mechanisms of governance. Transaction cost economics has had a pervasive influence on current economic thought about how and why institutions function as they do, and it has become a practical framework for research in organizations by representatives of a variety of disciplines. Through a transaction cost analysis, The Mechanisms of Governance shows how and why simple contracts give way to complex contracts and internal organization as the hazards of contracting build up. That complicates the study of economic organization, but a richer and more relevant theory of organization is the result. Many testable implications and lessons for public policy accrue to this framework. Applications of both kinds are numerous and growing. Written by one of the leading economic theorists of our time, The Mechanisms of Governance is sure to be an important work for years to come. It will be of interest to scholars and students of economics, organization, management, and law.

The Ego and the Mechanisms of Defence

Author: Anna Freud
Publisher: Karnac Books
ISBN: 9781855750388
Release Date: 1992-01-01
Genre: Psychology

When The Ego and the Mechanisms of Defense was first published in German in 1936 it was at once recognized as a major contribution to psychoanalytic psychology, and its translation into English quickly followed. More than half a century later it enjoys the status of a classic. Written by a pioneer of child analysis, and illustrated by fascinating clinical pictures drawn from childhood and adolescence, it discusses those adaptive measures by which painful and unwanted feeling-states are kept at bay or made more bearable. Anna Freud's arguments have a clarity and cogency reminiscent of her father's and the work is remarkable undated. Nothing stands still, but The Ego and the Mechanisms of Defense has unmistakably passed the test of time.

Fundamentals of Kinematics and Dynamics of Machines and Mechanisms

Author: Oleg Vinogradov
Publisher: CRC Press
ISBN: 1420042335
Release Date: 2000-07-25
Genre: Technology & Engineering

The study of the kinematics and dynamics of machines lies at the very core of a mechanical engineering background. Although tremendous advances have been made in the computational and design tools now available, little has changed in the way the subject is presented, both in the classroom and in professional references. Fundamentals of Kinematics and Dynamics of Machines and Mechanisms brings the subject alive and current. The author's careful integration of Mathematica software gives readers a chance to perform symbolic analysis, to plot the results, and most importantly, to animate the motion. They get to "play" with the mechanism parameters and immediately see their effects. A CD-ROM packaged with the book contains Mathematica-based programs for suggested design projects. As useful as Mathematica is, however, a tool should not interfere with but enhance one's grasp of the concepts and the development of analytical skills. The author ensures this with his emphasis on the understanding and application of basic theoretical principles, unified approach to the analysis of planar mechanisms, and introduction to vibrations and rotordynamics.

Defense Mechanisms

Author: Uwe Hentschel
Publisher: Elsevier
ISBN: 0080477070
Release Date: 2004-06-12
Genre: Psychology

The book is focused on defense mechanisms as theoretical constructs as well as the possibilities of their empirical registration by different methods, and the application of these constructs in different fields of psychology with special regard to concurrent and predictive validity. It is argued that defense mechanisms are in many ways to be seen as integrative constructs, not necessarily restricted to psychoanalytic theory and that the potential fields of their application have a wide ranging scope, comprising many fields of psychology. Consequently empirical studies are presented from the fields of clinical and personality psychology, psychotherapy research and psychosomatic phenomena and diseases. Methodological questions have a heavy weight in most of these studies. Provides coverage of relevant literature Covers different fields of application Attempts an integration of the contstruct of defense mechanisms into mainstream psychology Provides explanations of the theoretical basis of the construct of defense mechanisms

Concerted Organic and Bio Organic Mechanisms

Author: Andrew Williams
Publisher: CRC Press
ISBN: 0849391431
Release Date: 1999-10-27
Genre: Science

The concept of concerted mechanisms was formulated nearly 90 years ago and virtually all general organic chemistry texts mention it. Until now, however, no monograph has addressed the concept explicitly. Over the last two decades, substantial advancements made in the development of precise methods for elucidating concerted mechanisms have heightened the need for a comprehensive text on the subject. Concerted Organic and Bio-organic Mechanisms gathers the salient materials related to this emerging field into a single text. It sets forth the precise definition of concertedness-along with working sub-definitions-and describes rigorous experimental tools chemists can use to diagnose the existence or absence of concerted mechanisms. Advances in our understanding of concerted mechanisms lead to further questions. Concerted Organic and Bio-organic Mechanisms provides the background and the tools researchers need to consider these important questions and further advance the frontiers of reactions, synthesis, and catalysis.
