War and Aesthetics: Art, Technology, and the Futures of Warfare (Prisms: Humanities and War #1)

by Jens Bjering, Anders Engberg-Pedersen, Solveig Gade, and Christine Strandmose Toft

A provocative edited collection that takes an original approach toward the black box of military technology, surveillance, and AI—and reveals the aesthetic dimension of warfare.War and Aesthetics gathers leading artists, political scientists, and scholars to outline the aesthetic dimension of warfare and offer a novel perspective on its contemporary character and the construction of its potential futures. Edited by a team of four scholars, Jens Bjering, Anders Engberg-Pedersen, Solveig Gade, and Christine Strandmose Toft, this timely volume examines warfare through the lens of aesthetics, arguing that the aesthetic configurations of perception, technology, and time are central to the artistic engagement with warfare, just as they are key to military AI, weaponry, and satellite surveillance.People mostly think of war as the violent manifestation of a political rationality. But when war is viewed through the lens of aesthesis—meaning perception and sensibility—military technology becomes an applied science of sensory cognition. An outgrowth of three war seminars that took place in Copenhagen between 2018 and 2021, War and Aesthetics engages in three main areas of inquiry—the rethinking of aesthetics in the field of art and in the military sphere; the exploration of techno-aesthetics and the wider political and theoretical implications of war technology; and finally, the analysis of future temporalities that these technologies produce. The editors gather various traditions and perspectives ranging from literature to media studies to international relations, creating a unique historical and scientific approach that broadly traces the entanglement of war and aesthetics across the arts, social sciences, and humanities from ancient times to the present. As international conflict looms between superpowers, War and Aesthetics presents new and illuminating ways to think about future conflict in a world where violence is only ever a few steps away.ContributorsLouise Amoore, Ryan Bishop, Jens Bjering, James Der Derian, Anthony Downey, Anders Engberg-Pedersen, Solveig Gade, Mark B.

The Water, Energy, and Food Security Nexus in Asia and the Pacific: The Pacific (Water Security in a New World)

by Andrew Dansie Heidi K. Alleway Benno Böer

This open access book considers the water, energy, food (WEF) nexus in the Pacific region. The region comprises seventeen sovereign countries and seven territories spread across the Pacific Ocean, a blue expanse that covers a fifth of the world’s surface area but contains only 0.5% of the population—or 44.5 million people. The uniqueness of the Pacific and the need for a Pasifika-led approach to sustainability across environmental, societal and economical spheres requires this blue continent to be considered in a separate volume under the ‘Water Security in a New World’ series.This Pacific volume is focussed on water, energy and food security in Pacific Island Countries and Territories (PICTs) and the challenges produced by the impacts of anthropogenic climate change and human population pressures. The diversity of culture, traditional knowledge and ways of life across the Pacific are united by similar geographies and opportunities to apply a ‘Pacific specific’ WEF nexus approach; a coordinated approach to manage water, energy and food that is centred on active decision making across the three sectors to increase the security of each. Importantly, a WEF nexus approach builds on national and international efforts to date in the Pacific which include Integrated Water Resource Management, Ridge to Reef, Source to Sea, UNESCO Biosphere Reserves, Integrated Coastal Zone Management and other similar approaches.In this book, contributions by authors from governments, regional bodies, multilateral agencies, and academia describe water security and its intersectionality with both the energy and food sectors, highlighting the significance of both land and marine food systems and connectivity between water and energy in a Pacific-focussed context. It is demonstrated that these systems cannot be separated from the challenges associated with healthy environments and functioning ecological services, transport, and waste that are unique to this vast archipelagic region. To achieve meaningful change, it is essential that solutions are cognizant of the world’s colonial past and the global inequalities that persist today. The path forward for water and food systems is one that is Pasifika-led and builds on traditional knowledge and local capacity. National energy demands must consider the future with solutions comprising both WEF-integrated approaches and new energy technologies to hasten the transition away from fossil fuels. Globally, major greenhouse gas emitters both past and present need to step up for the environmental and economic benefit of all by rapidly reducing greenhouse gas emissions and supporting Pasifika leadership on highly ambitious net zero goals.This book is a highly recommended source of information and inspiration for policy makers, decision makers, research communities and practitioners dealing with any aspect of water, energy, or food security in the Pacific.

Water Politics and the On-Paper Hydropower Boom: Power, Corruption, and Sustainability in Emerging Economies (Earthscan Studies in Water Resource Management)

by Özge Can Dogmus

This book examines how the on-paper hydropower boom impacts the safe and fair access to water and energy in emerging economies.The global hydropower boom is largely made up of small hydropower plants located in emerging economies, but a lack of funding, over-ambitious planning, and corruption have halted the production of these projects. Describing this state as the ‘on-paper’ hydropower boom, this book shifts attention to the hydrosocial problems arising from hydropower projects that remain on paper. It examines how these proposed but unbuilt projects can lead to disruptions in the control and governance of water resources and increase the international dependence of emerging countries due to deep problems in their sustainable development planning and how all this can affect both ecosystems and the communities that depend on them. In doing so, it critically examines the dominant discourses on energy security and sustainable development, emphasises the extent to which the effects of global imperialism are at play, and examines the effects of international power relations in the hydrosocial context and their implications for perpetuating international relations of dependency. Further, this book provides a unique perspective on the global hydropower boom by highlighting that although the global hydropower boom largely remains on paper, it can still have a significant impact on human–water systems. Contributing to the debate on hydrosocial relationships, each chapter offers an insightful examination of the social, cultural, and political interactions that humans have with water and uses these insights to provide a nuanced understanding of the challenges and issues associated with on-paper plans.This book will be of great interest to students and scholars of water politics, water governance, political ecology, corruption and environmental economics, as well as sustainable development policymakers.

Water Treatment in Urban Environments: Examples from South/Southeast Asia (Applied Environmental Science and Engineering for a Sustainable Future)

by Veeriah Jegatheesan Perlie Velasco Nevelina Pachova

The value of implementing nature-based solutions (NbS) for water treatment in urban environments is increasingly recognized due to the multiple ecosystem services and societal benefits they provide. The successful implementation of NbS for urban water treatment, however, depends on a range of diverse technical and societal factors that need to be taken into account. Those vary by the type of NbS implemented, the societal challenges the NbS are designed to address and the local ecological, socio-economic and political context, in which the solutions are implemented. This book provides a collection of guidelines for the implementation of three types of NbS for water treatment in urban environments across cities in South/Southeast Asia, namely constructed wetlands, green roofs and floating treatment wetlands. The guides were developed based on existing experiences with the establishment, operation, and maintenance of those three types of NbS in three different countriesin South/Southeast Asia and the lessons learnt from their implementation. They provide detailed outlines of suggested steps for ensuring successful implementation in the respective local contexts. Those include overall planning schemes, surveys for socio-economic evaluations, suggested methods for construction and associated costs, required maintenance as well as a range of operational monitoring parameters. It also includes examples of approaches for the scaling of the three types of NbS discussed in the book in their respective local contexts. This book is expected to benefit local government units and contractors, and other stakeholders involved in NbS implementation and up-scaling, as well as researchers and postgraduate students who plan to conduct pilot-scale studies on NbS.

Wave Dispersion Characteristics of Continuous Mechanical Systems‏

by Farzad Ebrahimi

Wave Dispersion Characteristics of Continuous Mechanical Systems provides a mechanical engineering-based analysis of wave dispersion response in various structures created from different materials. Looking at materials including strengthened nanocomposites, functionally graded materials, metal foams, and anisotropic materials, it uses analytical solution methods to solve typical problems in the framework of a micromechanics approach. Nanocomposites are a novel type of composite materials, fabricated by dispersing nanosized reinforcements in a matrix to combine the material properties of the matrix with the improved properties of nanosized elements. This book enables readers to learn about the theory and practical applications of this rapidly evolving field. Practically minded, the book investigates the impact of employing various nanofillers and demonstrates how this augments stiffness within the nanocomposite. Topics covered include agglomeration and waviness of nanofillers, porosity, elastic mediums, fluid flow, and the impact of the thermal environment on a propagated wave. Using mathematical formulations to solve wave dispersion characteristics of structures including beams, plates, and shells, the book obtains equations of structures using first- and higher-order shear deformation theories. This book will be of interest to professional engineers working in material and mechanical engineering, nanocomposites, nanofillers, and micromechanics. It will also be of interest to students in these fields.

Ways of Greening: Using Plants and Gardens for Healthy Work and Living Surroundings

by Stevie Famulari

This book focuses on rethinking working and living spaces and understanding how "greening" can make them healthier and their occupants happier. It teaches how to see unique ideas for spaces and some of the materials needed to create the designs. Inspired by a study that states that 8% of a space needs to have plants in order to positively affect the air quality of the space, this book explores what that minimum would look like in spaces and how it can be done to existing spaces as well as to new site designs, greening both interiors and exteriors. Using the mathematical amount of 10% per square foot, the illustrations start at that quantity of greening and show how it can look. The sites selected are both public and private sites, as well as interior and exterior. As there are more modalities, needs, and locations where people now work, making sure that multiple types of spaces are designed for people’s success is more relevant than ever. This includes designs for more traditional offices, open-air offices, commercial spaces, homes, studios, and more. Ways of Greening: using Plans and Gardens for Healthy Work and Living Surroundings gives readers a way to not only understand greening but to understand how to see greening applied to their place. The two basic ways to see the spaces selected are existing spaces to which greening design is applied afterward and upcoming spaces in which greening design can be built directly into the space. The first type of retrofitting greening into existing spaces can also be combined with the second type of space (new designs). There are examples of both types throughout the book. Essentially, this book addresses ways in which business owners, residents, developers, architects, agencies, and others can integrate greening to improve the air quality and the quality of life with a green solution.

Weakly Nonlinear Systems: With Applications in Communications Systems (Understanding Complex Systems)

by Federico Beffa

The open access book covers a large class of nonlinear systems with many practical engineering applications. The approach is based on the extension of linear systems theory using the Volterra series. In contrast to the few existing treatments, our approach highlights the algebraic structure underlying such systems and is based on Schwartz’s distributions (rather than functions). The use of distributions leads naturally to the convolution algebras of linear time-invariant systems and the ones suitable for weakly nonlinear systems emerge as simple extensions to higher order distributions, without having to resort to ad hoc operators. The result is a much-simplified notation, free of multiple integrals, a conceptual simplification, and the ability to solve the associated nonlinear differential equations in a purely algebraic way. The representation based on distributions not only becomes manifestly power series alike, but it includes power series as the description of the subclass of memory-less, time-invariant, weakly nonlinear systems. With this connection, many results from the theory of power series can be extended to the larger class of weakly nonlinear systems with memory. As a specific application, the theory is specialised to weakly nonlinear electric networks. The authors show how they can be described by a set of linear equivalent circuits which can be manipulated in the usual way. The authors include many real-world examples that occur in the design of RF and mmW analogue integrated circuits for telecommunications. The examples show how the theory can elucidate many nonlinear phenomena and suggest solutions that an approach entirely based on numerical simulations can hardly suggest. The theory is extended to weakly nonlinear time-varying systems, and the authors show examples of how time-varying electric networks allow implementing functions unfeasible with time-invariant ones. The book is primarily intended for engineering students in upper semesters and in particular for electrical engineers. Practising engineers wanting to deepen their understanding of nonlinear systems should also find it useful. The book also serves as an introduction to distributions for undergraduate students of mathematics.

Weapons in Space: Technology, Politics, and the Rise and Fall of the Strategic Defense Initiative

by Aaron Bateman

A new and provocative take on the formerly classified history of accelerating superpower military competition in space in the late Cold War and beyond.In March 1983, President Ronald Reagan shocked the world when he established the Strategic Defense Initiative (SDI), derisively known as &“Star Wars,&” a space-based missile defense program that aimed to protect the US from nuclear attack. In Weapons in Space, Aaron Bateman draws from recently declassified American, European, and Soviet documents to give an insightful account of SDI, situating it within a new phase in the militarization of space after the superpower détente fell apart in the 1970s. In doing so, Bateman reveals the largely secret role of military space technologies in late–Cold War US defense strategy and foreign relations.In contrast to existing narratives, Weapons in Space shows how tension over the role of military space technologies in American statecraft was a central source of SDI&’s controversy, even more so than questions of technical feasibility. By detailing the participation of Western European countries in SDI research and development, Bateman reframes space militarization in the 1970s and 1980s as an international phenomenon. He further reveals that even though SDI did not come to fruition, it obstructed diplomatic efforts to create new arms control limits in space. Consequently, Weapons in Space carries the legacy of SDI into the post–Cold War era and shows how this controversial program continues to shape the global discourse about instability in space—and the growing anxieties about a twenty-first-century space arms race.
