Giants of Eclipse: The Aurigae Stars and Other Binary Systems

Giants of Eclipse: The Aurigae Stars and Other Binary Systems



The zeta Aurigae stars are the rare but illustrious sub-group of binary stars that undergo the dramatic phenomenon of ‘chromospheric eclipse’. This book provides detailed descriptions of the ten known systemsillustrates them richly with examples of new spectraand places them in the context of stellar structure and evolution.Comprised of a large cool giant plus a small hot dwarfthese key eclipsing binaries reveal fascinating changes in their spectra very close to total eclipsewhen the hot star shines through differing heights of the ‘chromosphere’or outer atmosphereof the giant star. The phenomenon provides astrophysics with the means of analyzing the outer atmosphere of a giant star and how that material is shed into space. The physics of these critical events can be explained qualitativelybut it is more challenging to extract hard facts from the observationsand tough to model the chromosphere in any detail.The book offers current thinking on mechanisms for heating a star’s chromosphere and on how a star loses massand relates this science synergistically to studies of other stars and binariesand to the increasing relevance of contributions from new techniques in interferometry and asteroseismology. It also includes a detailed discussion of the enigmatic star epsilon Aurigaewhich had recently undergone one of its very infrequent and very baffling eclipses. Though not a zeta Aurigae systemepsilon Aurigae is a true ‘Giant’ among eclipsing stars.The 7 chapters of this bookwritten by a group of expertshave been carefully edited to form a coherent volume that offers a thorough overview of the subject to both professional and student.


For many years Dr Griffin pursued research into stellar spectraprincipally of composite-spectrum binariesat Cambridge (UK)supporting it with observations acquired at major telescopes overseas. She now continues those interests in Canadaat the Dominion Astrophysical Observatory near Victoriaand makes her observations there. The prime research objectives are to determine the masses and other fundamental parameters of both component starsand to examine their evolutionary status. She also champions initiatives to recover the information in pre-digital (photographic) observations through programmes of appropriate digitization.Dr. Ake is a Program Director at Computer Sciences Corporation supporting the Hubble Space Telescopethe James Webb Space Telescopethe Milkulski Archive for Space Telescopesand the Kepler Data Management Center projects at Space Telescope Science Institute. His research interests center on evolved stars and binary systemsparticularly UV and FUV spectroscopic investigations from space of red giants and supergiants with hot secondary companions. He is currently studying the evolutionary status of cool stars with main sequence B- and A-type secondaries to refine the fundamental stellar parameters of the evolved components.,

Evolutionary Games in Complex Topologies

Evolutionary Games in Complex Topologies



There are many examples of cooperation in Nature: cells cooperate to form tissues, organs cooperate to form living organisms, and individuals cooperate to raise their offspring or to hunt. However, why cooperation emerges and survives in hostile environments, when defecting would be a much more profitable short-term strategy, is a question that still remains open. During the past few years, several explanations have been proposed, including kin and group selection, punishment and reputation mechanisms, or network reciprocity. This last one will be the center of the present study. The thesis explores the interface between the underlying structure of a given population and the outcome of the cooperative dynamics taking place on top of it, (namely, the Prisoner’s Dilemma Game). The first part of this work analyzes the case of a static system, where the pattern of connections is fixed, so it does not evolve over time. The second part develops two models for growing topologies, where the growth and the dynamics are entangled.

Weighing the World

Weighing the World



The book about John Michell (1724-93) has two parts. The first and longest part is biographical, an account of Michell ‘s home setting (Nottinghamshire in England), the clerical world in which he grew up (Church of England), the university (Cambridge) where he studied and taught, and the scientific activities he made the center of his life. The second part is a complete edition of his known letters. Half of his letters have not been previously published; the other half are brought together in one place for the first time. The letters touch on all aspects of his career, and because they are in his words, they help bring the subject to life. His publications were not many, a slim book on magnets and magnetism, one paper on geology, two papers on astronomy, and a few brief papers on other topics, but they were enough to leave a mark on several sciences. He has been called a geologist, an astronomer, and a physicist, which he was, though we best remember him as a natural philosopher, as one who investigated physical nature broadly. His scientific contribution is not easy to summarize. Arguably he had the broadest competence of any British natural philosopher of the eighteenth century: equally skilled in experiment and observation, mathematical theory, and instruments, his field of inquiry was the universe. From the structure of the heavens through the structure of the Earth to the forces of the elementary particles of matter, he carried out original and far-reaching researches on the workings of nature.

Sentimental Literature and Anglo-Scottish Identity, 1745-1820

Sentimental Literature and Anglo-Scottish Identity, 1745-1820



What did it mean to be British, and more specifically to feel British, in the century following the parliamentary union of Scotland and England? Juliet Shields departs from recent accounts of the Romantic emergence of nationalism by recovering the terms in which eighteenth- and early nineteenth-century writers understood nationhood. She argues that in the wake of the turmoil surrounding the Union, Scottish writers appealed to sentiment, or refined feeling, to imagine the nation as a community. They sought to transform a Great Britain united by political and economic interests into one united by shared sympathies, even while they used the gendered and racial connotations of sentiment to differentiate sharply between Scottish, English, and British identities. By moving Scotland from the margins to the center of literary history, the book explores how sentiment shaped both the development of British identity and the literature within which writers responded creatively to the idea of nationhood.

Computability

Computability



In the 1930s a series of seminal works published by Alan Turing, Kurt Gdel, Alonzo Church, and others established the theoretical basis for computability. This work, advancing precise characterizations of effective, algorithmic computability, was the culmination of intensive investigations into the foundations of mathematics. In the decades since, the theory of computability has moved to the center of discussions in philosophy, computer science, and cognitive science. In this volume, distinguished computer scientists, mathematicians, logicians, and philosophers consider the conceptual foundations of computability in light of our modern understanding. Some chapters focus on the pioneering work by Turing, Gdel, and Church, including the Church-Turing thesis and Gdel’s response to Church’s and Turing’s proposals. Other chapters cover more recent technical developments, including computability over the reals, Gdel’s influence on mathematical logic and on recursion theory and the impact of work by Turing and Emil Post on our theoretical understanding of online and interactive computing; and others relate computability and complexity to issues in the philosophy of mind, the philosophy of science, and the philosophy of mathematics.

Complete Chess Strategy 2

Complete Chess Strategy 2



Continuing his major work on strategy and tactics in modern chess, the internationally renowned Grandmaster, Ludek Pachman, now turns his attention to the play of the pawns and the achievement of control of the center squares. Though the pawns are the weakest pieces in chess, their importance in determining the character of the attack (and defense) and the development of strategic play cannot be underestimated. Pawns are essential to the protection of important squares and pieces. They are the best means of blockading enemy pawns and when correctly deployed, their advance can open vital files and diagonals, thereby creating weaknesses in the opposite position. Despite its limited power, the pawn has one special advantage over other pieces in that it can be promoted when it reaches the eighth rank; a successful pawn advance can completely change the balance of power and the outcome of a game. Pawns have aptly been described as ‘the soul of chess. Vital to chess mastery is a basic understanding of the importance of control of the center squares. The effectiveness of the pieces depend upon the strength of their position and center control creates a vital spatial superiority. The pieces gain in power as they exert influence over more spaces. Control not only allows increased maneuverability, but restricts the possibilities open to the opponent. The effective play of the pawns and center control have been touched upon in other works, but seldom with the insight and lucidity revealed in this second volume of Pachman’s masterwork.

Empires of Vision

Empires of Vision



Empires of Vision brings together pieces by some of the most influential scholars working at the intersection of visual culture studies and the history of European imperialism. The essays and excerpts focus on the paintings, maps, geographical surveys, postcards, photographs, and other media that comprise the visual milieu of colonization, struggles for decolonization, and the lingering effects of empire. Taken together, they demonstrate that an appreciation of the role of visual experience is necessary for understanding the functioning of hegemonic imperial power and the ways that the colonized subjects spoke, and looked, back at their imperial rulers. Empires of Vision also makes a vital point about the complexity of image culture in the modern world: We must comprehend how regimes of visuality emerged globally, not only in the metropole but also in relation to the putative margins of a world that increasingly came to question the very distinction between center and periphery.

The Price of Paradise

The Price of Paradise



Many American communities, especially the working and middle class, are facing chronic problems: fiscal stress, urban decline, environmental sprawl, failing schools, mass incarceration, political isolation, disproportionate foreclosures, and severe public health risks. In The Price of Paradise, David Dante Troutt argues that it is a lack of what he calls regional equity in our local decision making that has led to this looming crisis now facing so many cities and local governments. Unless we adopt policies that take into consideration all class levels, he argues, the underlying inequity affecting poor and middle class communities will permanently limit opportunity for the next generations of Americans. Arguing that there are structural flaws in the American dream, Troutt explores the role that place plays in our thinking and how we have organized our communities to create or deny opportunity. Through a careful presentation of this crisis at the national level and also through on-the-ground observation in communities like Newark, Detroit, Houston, Oakland, and New York City that all face similar hardships, he makes the case that Americas tendency to separate into enclaves in urban areas or to sprawl off on ones own in suburbs gravely undermines the American dream. Troutt shows that the tendency to separate also has maintained racial segregation in our cities and towns, itself cementing many barriers for advancement. A profound conversation about America at the crossroads, The Price of Paradise is a multilayered exploration of the legal, economic, and cultural forces that contribute to the squeeze on the middle class, the hidden dangers of growing income and wealth inequality, and environmentally unsustainable growth and consumption patterns. David Dante Troutt is Professor of Law and Justice John J. Francis Scholar at the Rutgers University-Newark Law School. He also serves as Director of the Center on Law in Metropolitan Equity at Rutgers Law School.Troutt is a columnist, novelist, and the author of several works of nonfiction, most recently After the Storm: Black Intellectuals Explore the Meaning of Hurricane Katrina.

Introduction to Variance Estimation

Introduction to Variance Estimation



We live in the information age. Statistical surveys are used every day to determine or evaluate public policy and to make important business decisions. Correct methods for computing the precision of the survey data and for making inferences to the target population are absolutely essential to sound decision making. Now in its second edition, Introduction to Variance Estimation has for more than twenty years provided the definitive account of the theory and methods for correct precision calculations and inference, including examples of modern, complex surveys in which the methods have been used successfully. The book provides instruction on the methods that are vital to data-driven decision making in business, government, and academe. It will appeal to survey statisticians and other scientists engaged in the planning and conduct of survey research, and to those analyzing survey data and charged with extracting compelling information from such data. It will appeal to graduate students and university faculty who are focused on the development of new theory and methods and on the evaluation of alternative methods. Software developers concerned with creating the computer tools necessary to enable sound decision-making will find it essential. Prerequisites include knowledge of the theory and methods of mathematical statistics and graduate coursework in survey statistics. Practical experience with real surveys is a plus and may be traded off against a portion of the requirement for graduate coursework. This second edition reflects shifts in the theory and practice of sample surveys that have occurred since the content of the first edition solidified in the early 1980s. Additional replication type methods appeared during this period and have featured prominently in journal publications. Reflecting these developments, the second edition now includes a new major chapter on the bootstrap method of variance estimation. This edition also includesextensive new material on Taylor series methods, especially as they apply to newer methods of analysis such as logistic regression or the generalized regression estimator. An introductory section on survey weighting has been added. Sections on Hadamard matrices and computer software have been substantially scaled back. Fresh material on these topics is now readily available on the Internet or from commercial sources. Kirk Wolter is a Senior Fellow at NORC, Director of the Center for Excellency in Survey Research, and Professor in the Department of Statistics, University of Chicago. He is a Fellow of the American Statistical Association and a Member of the International Statistical Institute. He is a past president of the International Association of Survey Statisticians and a past chair of the Survey Research Methods Section of the American Statistical Association. During the last 35 years, he has participated in the planning, execution, and analysis of large-scale complex surveys and has provided instruction in survey statistics both in America and around the world.




Writing Centers and the New Racism

Writing Centers and the New Racism



Noting a lack of sustained and productive dialogue about race in university writing center scholarship, the editors of this volume have created a rich resource for writing center tutors, administrators, and scholars. Motivated by a scholarly interest in race and whiteness studies, and by an ethical commitment to anti-racism work, contributors address a series of related questions: How does institutionalized racism in American education shape the culture of literacy and language education in the writing center? How does racism operate in the discourses of writing center scholarship/lore, and how may writing centers be unwittingly complicit in racist practices? How can they meaningfully operationalize anti-racist work? How do they persevere through the difficulty and messiness of negotiating race and racism in their daily practice? The conscientious, nuanced attention to race in this volume is meant to model what it means to be bold in engagement with these hard questions and to spur the kind of sustained, productive, multi-vocal, and challenging dialogue that, with a few significant exceptions, has been absent from the field.

Cognition Through Understanding

Cognition Through Understanding



Cognition Through Understanding presents a selection of Tyler Burge’s essays that use epistemology to illumine powers of mind. The essays focus on epistemic warrants that differ from those warrants commonly discussed in epistemology–those for ordinary empirical beliefs and for logical and mathematical beliefs. The essays center on four types of cognition warranted through understanding–self-knowledge, interlocution, reasoning, and reflection. Burge argues that by reflecting on warrants for these types of cognition, one better understands cognitive powers that are distinctive of persons, and (on earth) of human beings. The collection presents three previously unpublished independent essays, in addition to substantial, retrospective commentary. The retrospective commentary invites the reader to make connections that were not fully in mind when the essays were written.

Means Without End

Means Without End



An essential reevaluation of the proper role of politics in contemporary life. In this critical rethinking of the categories of politics within a new sociopolitical and historical context, the distinguished political philosopher Giorgio Agamben builds on his previous work to address the status and nature of politics itself. Bringing politics face-to-face with its own failures of consciousness and consequence, Agamben frames his analysis in terms of clear contemporary relevance. He proposes, in his characteristically allusive and intriguing way, a politics of gesturea politics of means without end.Among the topics Agamben takes up are the ‘properly’ political paradigms of experience, as well as those generally not viewed as political. He begins by elaborating work on biopower begun by Foucault, returning the natural life of humans to the center of the polis and considering it as the very basis for politics. He then considers subjects such as the state of exception (the temporary suspension of the juridical order); the concentration camp (a zone of indifference between public and private and, at the same time, the secret matrix of the political space in which we live); the refugee, who, breaking the bond between the human and the citizen, moves from marginal status to the center of the crisis of the modern nation-state; and the sphere of pure means or gestures (those gestures that, remaining nothing more than means, liberate themselves from any relation to ends) as the proper sphere of politics. Attentive to the urgent demands of the political moment, as well as to the bankruptcy of political discourse, Agambens work brings politics back to life, and life back to politics.Giorgio Agamben teaches philosophy at the Collge International de Philosophie in Paris and at the University of Macerata in Italy. He is the author of Language and Death (1991), Stanzas (1992), and The Coming Community (1993), all published by the University of Minnesota Press.
