Full textAbstract:
The main thread of chapter 3 introduces general relativity (GR), Big Bang cosmology, and closed timelike curves, showing how the ant’s-eye view leads to the puzzle of the creation of the universe, the horizon problem, the flatness problem, the low entropy problem, and the paradoxes of closed time-like curves. All these puzzles, problems, and paradoxes of the dynamical universe are resolved using the God’s-eye view of the adynamical block universe. Accordingly, Einstein’s equations of GR are not understood dynamically, but rather adynamically, that is, as a global self-consistency constraint between the spacetime metric and stress–energy tensor throughout the spacetime manifold. This is “spatiotemporal ontological contextuality” as applied to GR. The philosophical nuances such as the status of the block universe argument in GR and debates about the Past Hypothesis have been placed in Philosophy of Physics for Chapter 3. The associated formalism and computations are in Foundational Physics for Chapter 3.

Wildman, Wesley J. Anthropomorphism and Apophaticism. Oxford University Press, 2017. http://dx.doi.org/10.1093/oso/9780198815990.003.0002.
Full textAbstract:
To appreciate the risks and benefits of anthropomorphism, it is important (1) to appreciate the genius and limitations of human cognition, (2) to compare ultimacy models to see what difference anthropomorphic modeling techniques make, and (3) to entertain the possibility of an apophatic approach to ultimate reality that relativizes and relates ultimacy models. An apophatic approach to ultimate reality relativizes ultimacy models but also implies a disintegrating metric that serves to relate ultimacy models to one another. Degree of anthropomorphism is an important component of this disintegrating metric. Comparative analysis helps manifest internal complexity in the idea of anthropomorphism by distinguishing three relatively independent dimensions: Intentionality Attribution, Rational Practicality, and Narrative Comprehensibility. Educational efforts stabilized in cultural traditions can confer on people the desire and ability to resist one or more dimensions of the anthropomorphic default modes of cognition to some degree.

Bone, Robert G. Economics of Civil Procedure. Edited by Francesco Parisi. Oxford University Press, 2017. http://dx.doi.org/10.1093/oxfordhb/9780199684250.013.003.
Full textAbstract:
This chapter examines the law-and-economics approach to civil procedure. It argues that law and economics offers tools and insights that are relevant, indeed critical, to designing an optimal procedural system no matter what normative metric is applied. Section 8.2 begins the discussion by defining more precisely what is included in the category “civil procedure”. Section 8.3 then describes the law-and-economics approach in more detail and discusses some of its strengths and limitations. Section 8.4 illustrates the usefulness of this approach by applying it to three specific procedures: court-annexed mediation, pleading, and discovery. Section 8.5 concludes by summarizing the key contributions the law-and-economics approach has made to civil procedure analysis in general and outlining directions for future work.

Full textAbstract:
There is a remarkable analogy between Euler’s equations for a rigid body and his equations for an ideal fluid. The unifying idea is that of a Lie algebra with an inner product, which is not invariant, on it. The concepts of a vector space, Lie algebra, and inner product are reviewed. A hamiltonian dynamical system is derived from each metric Lie algebra. The Virasoro algebra (famous in string theory) is shown to lead to the KdV equation; and in a limiting case, to the Burgers equation for shocks. A hamiltonian formalism for two-dimensional Euler equations is then developed in detail. A discretization of these equations (using a spectral method) is then developed using mathematical ideas from quantum mechanics. Then a hamiltonian formalism for the full three-dimensional Euler equations is developed. The Clebsch variables which provide canonical pairs for fluid dynamics are then explained, in analogy to angular momentum.

Full textAbstract:
The three case studies included in this chapter illustrate well the unique barriers to bridging the implementation gap in cancer survivorship science and also potential solutions to address these barriers. The studies also reflect the spectrum of implementation readiness seen in today’s interventions, from being “ready for prime time” to establishing metrics for success and identifying the right intervention for a known problem. An overarching theme across all three survivorship science case studies is the focus on cancer rehabilitation. Cancer has the potential to adversely affect all aspects of an individual’s life, from physical to financial. Finding and delivering interventions to reduce risk before treatment starts and planning for recovery when treatment ends are needed to reduce the burden of cancer on individuals, families, and society.

Full textAbstract:
James Tenney talks about hierarchical temporal gestalt perception in music based on a metric space model, which he applied to compositions by Anton Webern, Edgard Varèse, and Claude Debussy. He begins with a discussion of temporal gestalt-units (TGs), using the terms “element,” “clang,” and “sequence” to designate TGs at the first three hierarchical levels of perceptual organization. He then considers a number of questions that might be the most relevant to musical perception, such as: how the perceptual boundaries of a TG are determined; or the extent to which the factors involved in temporal gestalt perception are objective. In an effort to provide some tentative answers to such questions, Tenney proposes a hypothesis of temporal gestalt perception and presents some results of a computer analysis program based on this hypothesis. The program, written by Larry Polansky, represents a simplified model of this aspect of musical perception, and Tenney describes some of the implications, limitations, and possible extensions of this model.

Koslowski, Rey. Shifts in Selective Migration Policy Models. Oxford University Press, 2018. http://dx.doi.org/10.1093/oso/9780198815273.003.0006.
Full textAbstract:
Selective migration policies can be grouped into three ideal-typical models: the Canadian ‘human capital’ model based on state selection of permanent immigrants using a points system; the Australian ‘neo-corporatist’ model based on state selection using a points system with extensive business and labour participation; and the market-oriented, demand-driven model based primarily on employer selection of migrants, as practised by the US. This chapter compares the selective migration polices of the three countries in terms of policy outcomes measured by varying metrics, examines policy implementation that diverges from the models, and explores a trend in all three countries towards recruiting foreign students to become immigrants. It finds that Canadian and Australian practices are shifting towards the US demand-driven model as employers rather than government officials are selecting increasing percentages of permanent immigrants from pools of temporary foreign workers and foreign students already in Canada and Australia rather than from abroad.

Malawey, Victoria. A Blaze of Light in Every Word. Oxford University Press, 2020. http://dx.doi.org/10.1093/oso/9780190052201.001.0001.
Full textAbstract:
A Blaze of Light in Every Word presents a conceptual model for analyzing vocal delivery in popular song recordings focused on three overlapping areas of inquiry: pitch, prosody, and quality. The domain of pitch, which refers to listeners’ perceptions of frequency, considers range, tessitura, intonation, and registration. Prosody, the pacing and flow of delivery, comprises phrasing, metric placement, motility, embellishment, and consonantal articulation. Qualitative elements include timbre, phonation, onset, resonance, clarity, paralinguistic effects, and loudness. Intersecting all three domains is the area of technological mediation, which considers how external technologies, such as layering, overdubbing, pitch modification, recording transmission, compression, reverb, spatial placement, delay, and other electronic effects, impact voice in recorded music. Though the book focuses primarily on the sonic and material aspects of vocal delivery, it situates these aspects among broader cultural, philosophical, and anthropological approaches to voice with the goal to better understand the relationship between sonic content and its signification. Drawing upon transcription and spectrographic analysis as the primary means of representation, as well as modes of analysis, this book features in-depth analyses of a wide array of popular song recordings spanning genres from indie rock to hip-hop to death metal, develops analytical tools for understanding how individual dimensions make singing voices both complex and unique, and synthesizes how multiple aspects interact to better understand the multidimensionality of singing voices.

Rose, Adam, Dan Wei, and Antonio Bento. Equity Implications of the COP21 Intended Nationally Determined Contributions to Reduce Greenhouse Gas Emissions. Oxford University Press, 2018. http://dx.doi.org/10.1093/oso/9780198813248.003.0004.
Full textAbstract:
This chapter examines the equity implications of the “bottom-up” approach to climate change negotiations by analyzing the individual country unconditional greenhouse gas reduction pledges specified in the COP21 Agreement of 2015. It compares the implications before and after emissions trading in terms of the standard equity metrics of the Gini coefficient and Atkinson index for three major countries/regions: the European Union, China, and California. The chapter adapts a nonlinear programming model well suited to this purpose that determines the equilibrium emissions allowance price, mitigation costs, and allowance purchases and sales from trading. It also tests the sensitivity of the results to macroeconomic conditions and technological change. The findings are that the pledges made at COP21 reflect substantial inequality in general and run counter to most equity principles. They are definitely a major departure from the Egalitarian, Vertical, and Rawlsian equity principles proposed for many years by developing countries.

Shrock, Dennis. Choral Monuments. Oxford University Press, 2017. http://dx.doi.org/10.1093/acprof:oso/9780190469023.001.0001.
Full textAbstract:
This book provides extensive and in-depth material about eleven epoch-making choral masterworks that span the history of Western culture from the Renaissance to the modern era. Included are Missa Pange lingua (Josquin Desprez); Missa Papae Marcelli (G. P. da Palestrina); B Minor Mass (J. S. Bach); Messiah (G. F. Handel); The Creation (Joseph Haydn); Symphony no. 9 (Ludwig van Beethoven); St. Paul (Felix Mendelssohn); Ein deutsches Requiem (Johannes Brahms); Messa da Requiem (Giuseppe Verdi); Mass (Igor Stravinsky); and War Requiem (Benjamin Britten). The works are presented in separate chapters, with each chapter divided into three basic sections—history, analysis, and performance practice. Discussions of history include biographical information about composers related to the work at hand, historical perspectives, and text sources. Analyses are focused on formal and musical structures, salient compositional techniques, and elements of music particular to the work being discussed, including parody and motivic organization. The discussion of performance practices includes primary source quotations about a wide range of topics, from performing forces, tempo, and phrasing of each work to specific issues such as tactus, text underlay, musica ficta, metric accentuation, rhythmic alteration, recitative, fermatas, and ornamentation. Musical examples and primary source quotes illuminate the material.

Full textAbstract:
The chapter describes the origins of the classical style, arguing that its elaboration involved experimentation rather than strict adherence to rules. It considers the contribution of three major theorists of the period to norms of language and style, exploring why in the end none could impose a single method. The chapter discusses the culture of literary quarrels, often conducted in witty poetic exchanges and staged comedies. Literary quarrels were a process taking place in the 1750s–1810s which helped stabilize conventions of taste and practice. The chapter features a case study that explains the creation of modern verse in Russia, detailing the basic aspects of prosody and the new metrical system.

Boules, Adel N. Fundamentals of Mathematical Analysis. Oxford University Press, 2021. http://dx.doi.org/10.1093/oso/9780198868781.001.0001.
Full textAbstract:
Fundamentals of Mathematical Analysis is a beginning graduate textbook on real and functional analysis, with a substantial component on topology. The three leading chapters furnish background information on the real and complex number fields, a concise introduction to set theory, and a rigorous treatment of vector spaces. Instructors can choose material from this part as their students’ background warrants. Chapter 4 is the spine of the book and is essential for an effective reading of the rest of the book. It is an extensive study of metric spaces, including the core topics of completeness, compactness, and function spaces, with a good number of applications. The remaining chapters consist of an introduction to general topology, a classical treatment of Banach and Hilbert spaces, the elements of operator theory, and a deep account of measure and integration theories. Several courses can be based on the book. The entire book is suitable for a two-semester course on analysis, and material can be chosen to design one-semester courses on topology, real analysis, or functional analysis. The book is designed as an accessible classical introduction to the subject, aims to achieve excellent breadth and depth, and contains an abundance of examples and exercises. The topics are carefully sequenced, the proofs are detailed, and the writing style is clear and concise. The only prerequisites assumed are a thorough understanding of undergraduate real analysis and linear algebra, and a degree of mathematical maturity.

Headrick, Daniel R. When Information Came of Age. Oxford University Press, 2001. http://dx.doi.org/10.1093/oso/9780195135978.001.0001.
Full textAbstract:
Although the Information Age is often described as a new era, a cultural leap springing directly from the invention of modern computers, it is simply the latest step in a long cultural process. Its conceptual roots stretch back to the profound changes that occurred during the Age of Reason and Revolution. When Information Came of Age argues that the key to the present era lies in understanding the systems developed in the eighteenth and early nineteenth centuries to gather, store, transform, display, and communicate information. The book provides a concise and readable survey of the many conceptual developments between 1700 and 1850 and draws connections to leading technologies of today. It documents three breakthroughs in information systems that date to the period: the classification and nomenclature of Linnaeus, the chemical system devised by Lavoisier, and the metric system. It shows how eighteenth-century political arithmeticians and demographers pioneered statistics and graphs as a means for presenting data succinctly and visually. It describes the transformation of cartography from art to science as it incorporated new methods for determining longitude at sea and new data on the measure the arc of the meridian on land. Finally, it looks at the early steps in codifying and transmitting information, including the development of dictionaries, the invention of semaphore telegraphs and naval flag signaling, and the conceptual changes in the use and purpose of postal services. When Information Came of Age shows that like the roots of democracy and industrialization, the foundations of the Information Age were built in the eighteenth and early nineteenth century.

Full textAbstract:
This chapter argues that Shakespeare’s wordplay is integral to his communication of ideas in audible and/or visual signs that must be interpreted by a reader or audience member. The essay builds on and counters Samuel Johnson’s famous critique of Shakespearean ‘quibbles’ as excessive deviations from a proper communicative path. Shakespeare’s theory and practice of wordplay does not accept the Johnsonian view that a word has a single or even a predominant ‘proper’ meaning. Paradoxically marked both by a concern for ‘measure’ (in syllable or line counting) and by a tendency toward transgression of rules, Shakespeare’s interest in ‘numbers’—a figure for poetry in metrical forms—shows his awareness of wordplay as a game requiring at least three players: a historically situated writer, a text (in Shakespeare’s case, usually an unstable one); and an interpreter. Key examples of wordplay come from As You Like It,Love’s Labours Lost, and the Sonnets, particularly 135, which plays on the word ‘will’ in ways some have found excessive.

Full textAbstract:
The focus of this article is stone tools. The history of stone tool research is linked integrally to the history of archaeology and the study of the human past, and many of the early developments in archaeology were connected with the study of stone artefacts. The identification of stone tools as objects of prehistoric human manufacture was central to the development of nineteenth-century models of prehistoric change, and especially the Three Age system for Old World prehistory. This article draws on concepts derived from interdisciplinary material culture studies to consider the role of the artefact after being discarded. It suggests that it is impossible to understand the meaning or efficacy of stone tools without understanding their ‘afterlives’ following abandonment. This article aims to complement contemporary metrical studies of the identification of stone tools and the description of their production. A brief history of the stone tools is explained and this concludes the article.

Full textAbstract:
In 2005, researchers from four Australian universities and CSIRO joined forces with environmental managers from three state agencies and six regional catchment management authorities to answer the question: 'Can we detect the influence of public environmental programs on the condition of our natural resources?' This was prompted by a series of national audits of Australia's environmental programs that could find no evidence of public investment improving the condition of waterways, soils and native vegetation, despite major public programs investing more than $4.2 billion in environmental repair over the last 20 years.
Landscape Logic describes how this collaboration of 42 researchers and environmental managers went about the research. It describes what they found and what they learned about the challenge of attributing cause to environmental change. While public programs had been responsible for increase in vegetation extent, there was less evidence for improvement in vegetation condition and water quality. In many cases critical levels of intervention had not been reached, interventions were not sufficiently mature to have had any measurable impact, monitoring had not been designed to match the spatial and temporal scales of the interventions, and interventions lacked sufficiently clear objectives and metrics to ever be detectable. In the process, however, new knowledge emerged on disturbance thresholds in river condition, diagnosing sources of pollution in river systems, and the application and uptake of state-and-transition and Bayesian network models to environmental management.
The findings discussed in this book provide valuable messages for environmental managers, land managers, researchers and policy makers.

Full textAbstract:
This book presents an in-depth deliberation on optical networks in four parts, capturing the past, present, and ensuing developments in the field. Part I has two chapters presenting an overview of optical networks and the enabling technologies. Part II has three chapters dealing with the single-wavelength optical networks: optical LANs/MANs, optical access networks using passive optical network architecture, SONET/SDH, optical transport network and resilient packet ring. Part III consists of four chapters on WDM-based optical networks, including WDM-based local/metropolitan networks (LANs/MANs) using single and multihop architectures over passive-star couplers, WDM/TWDM access networks as an extension of PONs with WDM transmission, WDM metro ring networks covering circuit-switched (using point-to-point WDM and wavelength-routed transmission) plus packet-switched architectures and WDM long-haul backbone networks presenting the offline and online design methodologies using wavelength-routed transmission. Part IV deals with some selected topics in six chapters. The first deals with transmission impairments and power-consumption issues in optical networks, while the next three chapters deal with the survivable optical networks, network control and management techniques, including GMPLS, ASON, and SDN/SDON, and datacenter networks using electrical, optical, and hybrid switching techniques. The final two chapters present elastic optical networks using flexible grid for better utilization of the optical-fiber spectrum and optical packet and burst-switched networks. The three appendices present the basics of the linear programming techniques, noise processes encountered in the optical communication systems, and the fundamentals of queuing theory and its applications in telecommunication networks.

Bannister, John. Great Whales. CSIRO Publishing, 2008. http://dx.doi.org/10.1071/9780643096196.
Full textAbstract:
Whales are mysterious and fascinating creatures. Despite modern technology, their world is still largely unexplored and unknown. They can only be seen, or rather glimpsed, when they are near the sea surface, either from boats, or perhaps from shore, or underwater by divers. They also reach astonishing sizes – the blue whale, for example, can grow to 30 metres in length, equivalent to the height of a six-storey building, and can weigh more than 130 tonnes.
Seven ‘Great Whales’ are found in the coastal waters surrounding Australia. These include six of the largest baleen whales – blue whale, fin whale, humpback whale, sei whale, Bryde’s whale and southern right whale – and the sperm whale, the largest toothed whale.
This book provides a detailed account of these extraordinary mammals. As well as the seven Great Whales, a smaller species – the minke whale – is included because of its special interest to Australians. The book describes whales’ highly specialised mammalian structure and biology, and the history of people’s association with them, at first through legend and wonder, then whaling, and more recently whale watching. It also looks at their past and current status, and the conservation initiatives that are in place to protect them from existing or potential threats.
With both historical and recent photographs, as well as an extensive glossary, Great Whales will be enjoyed by natural history enthusiasts, zoologists and students alike.

Verschuur, Gerrit L. Impact! Oxford University Press, 1996. http://dx.doi.org/10.1093/oso/9780195101058.001.0001.
Full textAbstract:
Most scientists now agree that some sixty-five million years ago, an immense comet slammed into the Yucatan, detonating a blast twenty million times more powerful than the largest hydrogen bomb, punching a hole ten miles deep in the earth. Trillions of tons of rock were vaporized and launched into the atmosphere. For a thousand miles in all directions, vegetation burst into flames. There were tremendous blast waves, searing winds, showers of molten matter from the sky, earthquakes, and a terrible darkness that cut out sunlight for a year, enveloping the planet in freezing cold. Thousands of species of plants and animals were obliterated, including the dinosaurs, some of which may have become extinct in a matter of hours. In Impact, Gerrit L. Verschuur offers an eye-opening look at such catastrophic collisions with our planet. Perhaps more important, he paints an unsettling portrait of the possibility of new collisions with earth, exploring potential threats to our planet and describing what scientists are doing right now to prepare for this awful possibility. Every day something from space hits our planet, Verschuur reveals. In fact, about 10,000 tons of space debris fall to earth every year, mostly in meteoric form. The author recounts spectacular recent sightings, such as over Allende, Mexico, in 1969, when a fireball showered the region with four tons of fragments, and the twenty-six pound meteor that went through the trunk of a red Chevy Malibu in Peekskill, New York, in 1992 (the meteor was subsequently sold for $69,000 and the car itself fetched $10,000). But meteors are not the greatest threat to life on earth, the author points out. The major threats are asteroids and comets. The reader discovers that astronomers have located some 350 NEAs ("Near Earth Asteroids"), objects whose orbits cross the orbit of the earth, the largest of which are 1627 Ivar (6 kilometers wide) and 1580 Betula (8 kilometers). Indeed, we learn that in 1989, a bus-sized asteroid called Asclepius missed our planet by 650,000 kilometers (a mere six hours), and that in 1994 a sixty-foot object passed within 180,000 kilometers, half the distance to the moon. Comets, of course, are even more deadly. Verschuur provides a gripping description of the small comet that exploded in the atmosphere above the Tunguska River valley in Siberia, in 1908, in a blinding flash visible for several thousand miles (every tree within sixty miles of ground zero was flattened). He discusses Comet Swift-Tuttle--"the most dangerous object in the solar system"--a comet far larger than the one that killed off the dinosaurs, due to pass through earth's orbit in the year 2126. And he recounts the collision of Comet Shoemaker-Levy 9 with Jupiter in 1994, as some twenty cometary fragments struck the giant planet over the course of several days, casting titanic plumes out into space (when Fragment G hit, it outshone the planet on the infrared band, and left a dark area at the impact site larger than the Great Red Spot). In addition, the author describes the efforts of Spacewatch and other groups to locate NEAs, and evaluates the idea that comet and asteroid impacts have been an underrated factor in the evolution of life on earth. Astronomer Herbert Howe observed in 1897: "While there are not definite data to reason from, it is believed that an encounter with the nucleus of one of the largest comets is not to be desired." As Verschuur shows in Impact, we now have substantial data with which to support Howe's tongue-in-cheek remark. Whether discussing monumental tsunamis or the innumerable comets in the Solar System, this book will enthrall anyone curious about outer space, remarkable natural phenomenon, or the future of the planet earth.
