The world population is growing, yet we continue to pursue higher levels of well-being, and as a result, increasing energy demands and the destructive effects of climate change are just two of many major threats that we face. Engineers play an indispensable role in addressing these challenges, and whether they recognize it or not, in doing so they will inevitably encounter a whole range of ethical choices and dilemmas. This book examines and explains the ethical issues in engineering, showing how they affect assessment, design, sustainability, and globalization, and explores many recent examples including the Fukushima Daiichi nuclear disaster, Dieselgate, 'naked scanners' at airports, and biofuel production. Detailed but accessible, the book will enable advanced engineering students and professional engineers to better identify and address the ethical problems in their practice.

In the last few years, Algorithms for Convex Optimization have revolutionized algorithm design, both for discrete and continuous optimization problems. For problems like maximum flow, maximum matching, and submodular function minimization, the fastest algorithms involve essential methods such as gradient descent, mirror descent, interior point methods, and ellipsoid methods. The goal of this self-contained book is to enable researchers and professionals in computer science, data science, and machine learning to gain an in-depth understanding of these algorithms. The text emphasizes how to derive key algorithms for convex optimization from first principles and how to establish precise running time bounds. This modern text explains the success of these algorithms in problems of discrete optimization, as well as how these methods have significantly pushed the state of the art of convex optimization itself.

Why do recordings of speakers engaging in reported speech at British Prime Minister's Questions from the 1970s–80s sound so distant to us? This cutting-edge study explores how the practices of quoting have changed at parliamentary question time in light of changing conventions and an evolving media landscape. Comparing data from authentic audio and video recordings from 1978 to 1988 and from 2003 to 2013, it provides evidence for qualitative and quantitative changes at the micro level (e.g., grammaticalisation processes in the reporting clause) and in more global structures (e.g., rhetorical patterns, and activities). These analytic findings contribute to the theoretical modelling of evidentiality in English, our understanding of constructions, interaction, and change, and of PMQs as an evolving community of practice. One of the first large-scale studies of recent change in an interactional genre of English, this ground-breaking monograph offers a framework for a diachronic interaction

Public opinion polls have become increasingly prominent during elections, but how they affect voting behaviour remains uncertain. In this work, we estimate the effects of poll exposure using an experimental design in which we randomly assign the availability of polls to participants in simulated election campaigns. We draw upon results from ten independent experiments conducted across six countries on four continents (Argentina, Australia, Canada, New Zealand, the United Kingdom, and the United States) to examine how polls affect the amount of information individuals seek and the votes that they cast. We further assess how poll effects differ according to individual-level factors, such as partisanship and political sophistication, and the content included in polls and how it is presented. Our work provides a comprehensive assessment of the power of polls and the implications for poll reporting in contemporary elections.

The story of how the UK Parliament came to use the Internet from the 1960s onwards has never been told. Electrified Democracy places the impact of technology on parliamentary workings in its longer term historical context. The author identifies repeating patterns of perception and analysis, and cultural tendencies in the perception of inventions dating back over centuries that have reasserted themselves in connection with the parliamentary response to networked computers. He uncovers evidence and makes new connections, while situating all this within the wider global debates on connections between communication and democracy in the age of the Internet, constitutional law and history, and 'law and technology'. This book will be of interest to a wide readership including policy makers, researchers, and all those interested in contemporary controversies about the role of the Internet in modern societies.

What does it take for warnings about violent conflict and war to be listened to, believed and acted upon? Why are warnings from some sources noticed and largely accepted, while others are ignored or disbelieved? These questions are central to considering the feasibility of preventing harm to the economic and security interests of states. Challenging conventional accounts that tend to blame decision-makers' lack of receptivity and political will, the authors offer a new theoretical framework explaining how distinct 'paths of persuasion' are shaped by a select number of factors, including conflict characteristics, political contexts, and source-recipient relations. This is the first study to systematically integrate persuasion attempts by analysts, diplomats and senior officials with those by journalists and NGO staff. Its ambitious comparative design encompasses three states (the US, UK, and Germany) and international organisations (the UN, EU, and OSCE) and looks in depth at four conf

The Neue Nationalgalerie, which was erected in 1965-68, is the only building by the architect Ludwig Mies van der Rohe in Germany from after the Second World War. With its steel roof over the glass-walled exhibition hall and its reduced design vocabulary, it is regarded as an icon of modernism and as the legacy of a visionary master builder. Following the restoration by the firm David Chipperfield Architects, the Neue Nationalgalerie is reopening with new glory in 2021. With numerous specialist texts and large-format photographs, the book focuses on the architecture of the museum in three thematic groups: the historical building, the fundamental restoration, and the renovated building. Detailed and large-format photographs heighten awareness of the unique architecture, which Mies van der Rohe designed down to the smallest detail.

Based on a close examination of more than 700 homicide trials, A Renaissance of Violence exposes the deep social instability at the core of the early modern states of North Italy. Following a series of crises in the early seventeenth century, interpersonal violence in the region grew to frightening levels, despite the efforts of courts and governments to reduce social conflict. In this detailed study of violence in early modern Europe, Colin Rose shows how major crises, such as the plague of 1630, reduced the strength of social bonds among both elite and ordinary Italians. As a result, incidents of homicidal violence exploded - in small rural communities, in the crowded urban center and within tightly-knit families. Combining statistical analysis and close reading of homicide patterns, Rose demonstrates how the social contexts of violence, as much as the growth of state power, can contribute to explaining how and why interpersonal violence grew so rapidly in North Italy in the seventee

After a trip to Japan in 1953, Werner Bl酲er published his landmark book on Classical Japanese architecture. His studies of 17th-18th-century wooden buildings document minimalist, grid-based structures using stark black-and-white photographs, some color photographs and numerous line drawings. His book, highly prized in terms of design and content, contributed significantly to introducing Japanese aesthetics to Western architecture, art and graphics. Mies van der Rohe, for example, gave it to many of his friends.The reprint is enriched by a text on the history of the book by Christian Blaser, Werner Blaser's son, a contribution by Inge Andritz on Mies van der Rohe and Japanese architecture, and a personal afterword by Tadao And.
