B Ordering Space

In the wake of globalization, numerous social scientists are turning to concepts of mobility, fluidity and hybridity to characterize a presumed de-territorialization and de-bordering of contemporary social and economic relations. This book brings together a select group of internationally renowned human geographers to explore the use of these concepts in relation to space, place and territory. In doing so, they (re)situate the subject of borders as active socio-spatial processes from a variety of theoretical perspectives. The contributors link debates on borders to discussions within the wider sphere of cultural studies, notably those addressing themes of migration, post-colonialism, the formation of national/regional identities and radical democratic practice. The chapters focus on those discursive practices that constitute 'bordered' geographical entities in the first instance through differentiated regimes of discourse. The book thus transcends the narrower field of borderlands research by building bridges to other domains of enquiry within political and human geography.

This book covers the principles, historical development, and applications of many acoustic logging methods, including acoustic logging-while-drilling and cased-hole logging methods. Benefiting from the rapid development of information technology, the subsurface energy resource industry is moving toward data integration to increase the efficiency of decision making through the use of advanced big data and artificial intelligence technologies, such as machine/deep learning. However, wellbore failure may happen if evaluations of risk and infrastructure are made using data mining methods without a complete understanding of the physics of borehole measurements. Processed results from borehole acoustic logging will constitute part of the input data used for data integration. Therefore, to successfully employ modern techniques for data assimilation and analysis, one must fully understand the complexity of wave mode propagation, how such propagation is influenced by the well, and the materials placed within the well (i.e., the cement, casing, and drill strings), and ultimately how waves penetrate into and are influenced by geological formations. State-of-the-art simulation methods, such as the discrete wavenumber integration method (DWM) and the finite difference method (FDM), are introduced to tackle the numerical challenges associated with models containing large material contrasts, such as the contrasts between borehole fluids and steel casings. Waveforms and pressure snapshots are shown to help the reader understand the wavefields under various conditions. Advanced data processing methods, including velocity analyses within the time and frequency domains, are utilized to extract the velocities of different modes. Furthermore, the authors discuss how various formation parameters influence the waveforms recorded in the borehole and describe the principles of both existing and potential tool designs and data acquisition schemes. This book greatly benefits from the research and knowledge generated over four decades at the Earth Resources Laboratory (ERL) of the Massachusetts Institute of Technology (MIT) under its acoustic logging program. Given its scope, the book is of interest to geophysicists (including borehole geophysicists and seismologists), petrophysicists, and petroleum engineers who are interested in formation evaluation and cementation conditions. In addition, this book is of interest to researchers in the acoustic sciences and to 4th-year undergraduate and postgraduate students in the areas of geophysics and acoustical physics.

In recent years the borders of Europe have been perceived as being besieged by a staggering refugee and migration crisis. The contributors to The Borders of "Europe" see this crisis less as an incursion into Europe by external conflicts than as the result of migrants exercising their freedom of movement. Addressing the new technologies and technical forms European states use to curb, control, and constrain what contributors to the volume call the autonomy of migration, this book shows how the continent's amorphous borders present a premier site for the enactment and disputation of the very idea of Europe. They also outline how from Istanbul to London, Sweden to Mali, and Tunisia to Latvia, migrants are finding ways to subvert visa policies and asylum procedures while negotiating increasingly militarized and surveilled borders. Situating the migration crisis within a global frame and attending to migrant and refugee supporters as well as those who stoke nativist fears, this timely volume demonstrates how the enforcement of Europe’s borders is an important element of the worldwide regulation of human mobility.

This book presents to the reader a modern axiomatic construction of three-dimensional Euclidean geometry in a rigorous and accessible form. It is helpful for high school teachers who are interested in the modernization of the teaching of geometry.

The act of surfing involves highly-skilled humans gliding, sliding, or otherwise riding waves of energy as they pass through water. As this book argues, however, this act of surfing does not exist in isolation. It is defined by the cultures and geographies that synergize with it – by the places, ideas, images, and other representations which at once reflect, create, and commodify this spatial practice. This book innovatively explores the spaces of surf and surf-riding, informed specifically by the perspective of human geography. Based on a range of critical turns within the social sciences, the book explores the locations, relational sensibilities, and transformative nature of surfing spaces, and examines how the spatial practice has been scripted by dominant surfing cultures. The book details how prescriptive (b)orders of access, entitlement, and marginalization have been created, and how, with the advent of new craft, media, and ideals, they are being actively challenged to redefine surfing spaces in the twenty-first century.

What are the wider implications of the arrangements for the Irish and UK constitutions? Northern Ireland presents some of the most difficult Brexit dilemmas. Negotiations between the UK and the EU have set out how issues like citizenship, trade, the border, human rights and constitutional questions may be resolved. But the long-term impact of Brexit isn’t clear. This thorough analysis draws upon EU, UK, Irish and international law, setting the scene for a post-Brexit Northern Ireland by showing what the future might hold.

This first volume of a two-volume overview covers the basic theory of Banach spaces, harmonic analysis and probability.
