New technologies and scientific imagination rearrange the boundary that we identify as the beginning and end of life. New techno-social constellations, such as the ever-increasing presence of digital avatars and genetic screenings, implore us to reconsider and transcend the existing definitions of life and death. Through a multidisciplinary approach, this volume explores how the limitations and perceived finality of life and death are reconstituted through engagements with modern technology.

This book is dedicated to the history and contemporary activities of IGIP that occupies a unique position among world organizations who are focused on Engineering Education. We are currently in the process of transforming education at all levels. This applies in particular to the professional and academic education and training of engineers.To face these current real-world challenges, higher education has to find innovative ways to quickly respond to these new needs. This and completely new technologies in education require specifically new and adapted approaches in Engineering Pedagogy.This book is a continuation of IGIP's tradition to summarize and analyze intermediate results and foresee the main trends of further development of Engineering Pedagogy. It is written for the 50th anniversary of IGIP and contains valuable historic information as well as memories and opinions of IGIP members and specialists in Engineering Pedagogy.This book is intended for teachers at technical colleges and universities, students, post-graduates, administrative staff of educational institutions, staff of state educational ministries and committees, members of other societies with interest in Engineering Education, staff of personnel agencies, and everyone who is interested in Engineering Education and Pedagogy. Interested readership includes furthermore policymakers, academic researchers in pedagogy and learning theory, schoolteachers, the learning industry, further and continuing education lecturers, etc.

This volume is a collection of essays of a philosophical nature on the subject of technology, introducing authors from the Portuguese-speaking community, namely from Portugal itself, Africa and Brazil. Their contributions detail a unique perspective on technology, placing this important topic within the historical, ideological and social contexts of their countries, all of which share a common language. The shared history of these countries and the cultural and economic specificities of each one have stimulated singular insights into these thinkers'reflections.The essays are thematically diverse. Among the topics covered are technogenic knowledge, visions of technology, risks and uncertainties, mediatization, digitalization, and datafication, engineering practice and ethics, alternative technoscientific strategies, ontotechnologies of the body, virtual and archive. The contributions also explore other themes that are more closely related to the semi-peripheral world, such as technological dependence and the incorporation of Western technology into the social structure of ancestral communities.This book appeals to students and researchers and provides a voice to authors whose work are not usually available in English-language publications. It serves as an ideal guide for all those who seek rigorous and geographically widespread knowledge regarding thinking on technology in several Portuguese-speaking countries.

The creation of physical and material infrastructure is the cornerstone of human development; not surprisingly, engineers and designers are often motivated and inspired in their practice to improve the world around them, to make things better for others, and to apply their knowledge for the good of mankind. These aspirations often get translated into engineering and design curricula where students and faculty work on development related projects usually under the category of community or service learning. This book presents an overview of such an education and outreach program designed to empower stakeholders to improve their lives. The project described here was an international multi-institutional undertaking that included academic institutions, non-governmental organizations, and private firms. Within the academic setting, an interdisciplinary set of actors that included engineering and industrial design students and faculty worked on the project. We concretize our work by presenting a design case study that illustrates how different approaches can help guide the works of engineers and designers as they create global infrastructures and localized artifacts. We emphasize the importance of developing long term relationships with organizations on the ground in order to ensure appropriate design as well as successful transfer and long term use of designed artifacts. We discuss the life trajectories of the authors to provide a grounded perspective on what motivated us to undertake this work and shaped our approach with the intention to demonstrate that there are multiple paths toward this goal. Table of Contents: Introduction / Development of the Program: Personal Trajectories Meet Professional Opportunities / Intellectual Positioning of the Program: Sociomaterial Infrastructures and Capable and Convivial Design / Case Study: Quick Response (QR) Code Based Immunization Solution / Design for Development Course and Outreach Initiative / Conclusion: Lessons Learned

At the University of Rhode Island over 25% of engineering undergraduates simultaneously complete a second degree in German, French, Spanish, or Chinese. They furthermore spend an entire year abroad, one semester as exchange students at a partner university and six months as professional engineering interns at a cooperating company. With a close-to 100% placement rate, over 400 graduates, and numerous national awards, the URI International Engineering Program (IEP) is a proven path of preparation for young engineers in today's global workplace. The author of this volume, John Grandin, is an emeritus professor of German who developed and led the IEP for twenty-three years. In these pages, he provides a two-pronged approach to explain the origin and history of this program rooted in such an unusual merger of two traditionally distinct higher education disciplines. He looks first at himself to explain how and why he became an international educator and what led him to his lasting passion for the IEP. He then provides an historical overview of the program's origin and growth, including looks at the bumps and bruises and ups and downs along the way. Grandin hopes that this story will be of use and value to other educators determined to reform higher education and align it with the needs of the 21st Century.

This book follows the fraught attempts of engineers to identify with Korea as a whole. It is for engineers, both Korean and non-Korean, who seek to become better critical analysts of their own expertise, identities, and commitments. It is for non-engineers who encounter or are affected by Korean engineers and engineering, and want to understand and engage them. It is for researchers who serve as critical participants in the making of engineers and puzzle over the contents and effects of techno-national formation.

Global engineering offers the seductive image of engineers figuring out how to optimize work through collaboration and mobility. Its biggest challenge to engineers, however, is more fundamental and difficult: to better understand what they know and value qua engineers and why. This volume reports an experimental effort to help sixteen engineering educators produce''personal geographies''describing what led them to make risky career commitments to international and global engineering education. The contents of their diverse trajectories stand out in extending far beyond the narrower image of producing globally-competent engineers. Their personal geographies repeatedly highlight experiences of incongruence beyond home countries that provoked them to see themselves and understand their knowledge differently. The experiences were sufficiently profound to motivate them to design educational experiences that could provoke engineering students in similar ways. For nine engineers, gaining new international knowledge challenged assumptions that engineering work and life are limited to purely technical practices, compelling explicit attention to broader value commitments. For five non-engineers and two hybrids, gaining new international knowledge fueled ambitions to help engineering students better recognize and critically examine the broader value commitments in their work. A background chapter examines the historical emergence of international engineering education in the United States, and an epilogue explores what it might take to integrate practices of critical self-analysis more systematically in the education and training of engineers. Two appendices and two online supplements describe the unique research process that generated these personal geographies, especially the workshop at the U.S. National Academy of Engineering in which authors were prohibited from participating in discussions of their manuscripts.

This book deals with the simultaneous making of Portuguese engineers and the Portuguese nation-state from the mid seventeenth century to the late twentieth century. It argues that the different meanings of being an engineer were directly dependent of projects of nation building and that one cannot understand the history of engineering in Portugal without detailing such projects. Symmetrically, the authors suggest that the very same ability of collectively imagining a nation relied on large measure on engineers and their practices. National culture was not only enacted through poetry, music, and history, but it demanded as well fortresses, railroads, steam engines, and dams. Portuguese engineers imagined their country in dialogue with Italian, British, French, German or American realities, many times overlapping such references. The book exemplifies how history of engineering makes more salient the transnational dimensions of national history. This is valid beyond the Portuguese case and draws attention to the potential of history of engineering for reshaping national histories and their local specificities into global narratives relevant for readers across different geographies.

Indicators are more and more applied to describe and analyze complex systems. Typical examples: Innovation potential of nations, child-well being, Environmental health, poverty, chemical pollution, corruption of nations. The task is: How can a system of indicators be defined in order to fulfill the above expectations. One possibility is the application of the mathematical theory of partial order, especially when the indicator system shall be used for ranking purposes.

This book examines the U.S. space program's triumphs and failures in order to assess what constitutes a successful space policy. Using NASA and the space industry's complex history as a guide, it draws global lessons about space missions and the trends we can expect from different nations in the next decade and beyond. Space exploration has become increasingly dependent on cooperation between countries as well as the involvement of private enterprise. This book thus addresses issues such as: Given their tenuous history, can rival countries work together? Can private enterprise fill NASA's shoes and provide the same expertise and safety standards? Written by a former NASA Aerodynamics Officer at Houston Mission Control working on the Space Shuttle program, the second edition of this book provides updated information on U.S. space policy, including the new strategy to return to the Moon prior to traveling to Mars. Additionally, it takes a look at the formation of the Space Force as a military unit, as well as the latest developments in private industry. Overall, it is a thought-provoking resource for both space industry professionals and space enthusiasts.

Die vorliegende Dissertation umfasst experimentelle Untersuchungen zu den Ursachen der Partikelentstehung in Ottomotoren mit Saugrohreinspritzung sowie die Ableitung möglicher Maßnahmen zur Optimierung der Gemischbildung und somit zur Verringerung der Partikelemission. Grundlegende Untersuchungen zur Gemischbildung wurden an einer Verdunstungskammer in der Gestalt eines Einlasskanals durchgeführt. Die Verdunstungsneigung verschiedener Sprayauslegungen konnten so bewertet werden. Zur Analyse und Minimierung von Kraftstoffwandfilmen wurden Aufnahmen an einem geschleppten Transparentmotor mit Glaszylinder mit Hilfe von High-Speed-Kameras realisiert. Hierdurch konnten Wandfilme innerhalb des Brennraums visualisiert und anhand ihrer Fläche quantifiziert werden. Eine Vielzahl von innermotorischen Einflussparametern auf die Partikelemission wurde schließlich an einem mit Endoskopen sowohl im Brennraum als auch im Saugrohr optisch zugänglichen Vollmotor untersucht. Drei dominierende Quellen für die Partikelentstehung im Brennraum von Ottomotoren mit Saugrohreinspritzung konnten dabei identifiziert werden: Kraftstoffwandfilme an den Einlassventilen, Wandfilme an der Zylinderlaufbuchse sowie Inhomogenitäten in der Gasphase. Die innermotorischen Parameter Motorlast, Motortemperatur, Ventilsteuerzeiten, Einspritztiming, Ladungsbewegung, Injektorsprayauslegung und Kraftstoffdruck wurden hinsichtlich ihres Einflusses auf die Partikelentstehung sowie auf ihr Potential zur Reduktion der Partikelemission untersucht und bewertet.

Zu Beginn eines Bauprojektes müssen Bauherren und -frauen zahlreiche Entscheidungen mit langfristigen Auswirkungen treffen. In Bezug auf die Energieeffizienz bildet die ENEV sowie die EEWärmeG die Grundlage der Gebäudeeffizienzgestaltung, zahlreiche'Upgrades'verkomplizieren die ohnehin schon unübersichtliche Situation. Das Buch zeigt eine Übersicht der möglichen Maßnahmen auf, bewertet Potentiale ökonomisch und ökologisch und beschreibt die Wechselwirkungen. Grundlagenkenntnisse zur Wärmeverlustberechung werden ebenso vermittelt wie die Funktionen der Energiewandlungssysteme (Wärmesysteme). Dadurch können Bauprojekte individuell bewertet werden. Das Buch zeigt auch auf, wann es lohnenswert sein kann, effizienter als Richtlinien es vorschreiben zu bauen. Auch im Zuge der Aufwertung einer Immobilie oder eines Umbaus hinsichtlich altersgerechten Wohnens stellt sich oft die Frage, ob eine Investition in eine verbesserte Energieeffizienz angebracht ist. Entsprechende Beratungsangebote kann dieses Buch unabhängig und fundiert begleiten.

Protected areas have often been defined as the backbones of biodiversity conservation. Protected areas have often been defined as the backbones of biodiversity conservation. However, legitimate demands formulated by countries for their economic development, growing human populations, forest fragmentations, and needs of local communities for sustainable livelihoods are also pressing demands on protected areas, stringently pressuring conservation community to identify means to reconcile long term biodiversity conservation and communities'livelihoods. Hence, integrating conservation activities within the global framework of economic development of countries with high biodiversity had become part of conservation paradigms. Integrated development as a route to conservation, strict protected areas, community managed areas, etc. have been tried but resulted in debatable outcomes in many ways. The lukewarm nature of these results brought ‘landscape approach'at the front of biodiversity conservation in Central Africa. Since the late 1990s the landscape approach uses large areas with different functional attributes and shifts foundational biodiversity conservation paradigms. Changes are brought to the role traditionally attributed to local communities, aligning sustainable development with conservation and stretching conservation beyond the confines of traditional protected areas. These three shifts need a holistic approach to respond to different conservation questions. There are only a few instances where the landscape experience has been scientifically documented and lessons learnt drawn into a corpus of knowledge to guide future conservation initiatives across Central Africa. To subjugate one biodiversity conservation landscape as one case study emerged as a matter of urgency to present the potential knowledge acquired throughout the landscape experiment, including leadership and management, processes tried, results (at least partially) achieved, and why such and such other process or management arrangement were been chosen among many other alternatives, etc. The challenges of the implementation of the conservation landscape approach needed also to be documented. This book responds to the majority of these questions; drawing its content from the firsthand field knowledge, it discusses these shifts and documents what has been tried, how successful (unsuccessful) it was, and what lessons learnt from these trials. Theoretical questions such as threat index, and ecological services, etc. are also discussed and gaps in knowledge are identified.

The book presents thirty great Chinese inventions, both ancient and modern, which are original, distinct, have made outstanding contributions and had extensive influence in China and around the globe. It also clarifies the misunderstandings and provides a clear definition and classification of the evaluation criteria for great inventions. Each invention is presented with color pictures and comprehensive discussions. The book not only offers readers the fascinating stories behind the greatest inventions of all time from China, such as the compass, paper, and tea making & planting, but also allows them to be inspired by the great Chinese inventors'inherent spirit of innovation and creativity.

The aim of the present thesis is to examine the cognitive control mechanisms underlying auditory selective attention by considering the influence of variables that increase the complexity of an auditory scene. Therefore, technical aspects such as dynamic binaural hearing, room acoustics and head movements as well as those that influence the efficiency of cognitive processing are taken into account. Step-by-step the well-established dichotic-listening paradigm is extended into a realistic spatial listening paradigm. Conducted empirical surveys are based on a paradigm examining the intentional switching of auditory selective attention. Performance measure differences between the repetition of the target's spatial position and the related switch describe the loss of efficiency associated with redirecting attention from one target's location to another. To examine whether the irrelevant auditory information is decoded, interference in the processing of task-relevant and task-irrelevant information is created in the paradigm. Using the binaural-listening paradigm, the ability to intentionally switch auditory selective attention is tested when applying different methods of spatial reproduction. Essential differences between real sources, an individual and a non-individual binaural synthesis are found. As a step towards multi-talker scenarios in realistic environments participants are tested in differently reverberating environments, resulting in highly affected switch costs. Age-related effects are found when applying the binaural-listening paradigm, indicating difficulties for elderly to suppress processing the distractor's speech.

Zentrifugal-Partikelreceiver stellen eine neuartige Komponente für die konzentrierende solare Energiegestehung (CSP) dar. Sie werden in punktfokussierenden CSP-Kraftwerken eingesetzt und gehören - im Gegensatz zu den bereits im Markt befindlichen indirekt absorbierenden Rohrreceivern - der Gruppe der direktabsorbierenden Receiver an. Als Wärmeträgermedium wird hierbei Granulat genutzt, wie beispielsweise Bauxit-Proppants. Bauxit als Wärmeträgermedium ermöglicht höhere Prozesswirkungsgrade aufgrund von höheren Anwendungstemperaturen als in aktuell kommerziell eingesetzten, indirekt absorbierenden Systemen. Gleichzeitig ist Bauxit-Granulat als Wärmespeichermedium einsetzbar, da es besonders kostengünstig ist. Das Potential des Zentrifugal-Partikelreceiver wurde bereits erfolgreich in einem 15kWth Laborreceiver am Deutschen Zentrum für Luft- und Raumfahrt e.V. bewiesen. Darauf aufbauend verfolgt diese Arbeit das Ziel, die Strömungsmechanik von fließenden Granulaten zu modellieren.

An introduction to dimensional analysis, a method of scientific analysis used to investigate and simplify complex physical phenomena, demonstrated through a series of engaging examples.This book offers an introduction to dimensional analysis, a powerful method of scientific analysis used to investigate and simplify complex physical phenomena. The method enables bold approximations and the generation of testable hypotheses. The book explains these analyses through a series of entertaining applications; students will learn to analyze, for example, the limits of world-record weight lifters, the distance an electric submarine can travel, how an upside-down pendulum is similar to a running velociraptor, and the number of Olympic rowers required to double boat speed.The book introduces the approach through easy-to-follow, step-by-step methods that show how to identify the essential variables describing a complex problem; explore the dimensions of the problem and recast it to reduce complexity; leverage physical insights and experimental observations to further reduce complexity; form testable scientific hypotheses; combine experiments and analysis to solve a problem; and collapse and present experimental measurements in a compact form. Each chapter ends with a summary and problems for students to solve. Taken together, the analyses and examples demonstrate the value of dimensional analysis and provide guidance on how to combine and enhance dimensional analysis with physical insights. The book can be used by undergraduate students in physics, engineering, chemistry, biology, sports science, and astronomy.

Das Wachstum des zivilen Luftverkehrs bedeutet eine große Herausforderung für die Luftfahrtbranche. Nur durch effizientere Triebwerke können der spezifische Verbrauch von fossilen Energieträgern und die spezifischen Emissionen reduziert werden und so der Zugang zu Flugreisen für die wachsende Weltbevölkerung sichergestellt werden. Einen maßgeblichen Beitrag zur Steigerung der Effizienz kann die Optimierung der Kühlung von heißen Komponenten des Kerntriebwerks leisten. Gerade im thermisch hoch belasteten Bereich der ersten Turbinenstufen werden große Mengen an Kühlluft verwendet, die sich negativ auf den thermischen Wirkungsgrad auswirken. Neue Kühlverfahren ermöglichen es, den Kühlluftbedarf bei gleichen Standzeiten der Bauteile zu verringern. Vor einem möglichen Einsatz müssen diese neuen Verfahren untersucht und ihre Leistungsfähigkeit bestimmt werden, vor allem die Vorhersage der Materialtemperatur der Schaufeln muss hoch präzise erfolgen. Die vorliegende Arbeit präsentiert neue Verfahren zur Kühlung von Rotorschaufeln. Es wird speziell auf die Drallkühlung eingegangen, die sich in grundlegenden Untersuchungen und in Verbindung mit den sich rapide verbessernden Möglichkeiten der additiven Fertigung als vielversprechendes Verfahren herausgestellt hat. Zur Beurteilung der neuen Konzepte werden Untersuchungen durchgeführt, bei denen die wichtigen strömungsmechanischen Ähnlichkeitskennzahlen der Maschine eingehalten werden. So können die Ergebnisse unmittelbar auf den Einsatz im Triebwerk übertragen werden. Die Untersuchungen bedeuten eine Herausforderung für die als Messtechnik eingesetzte Infrarotthermographie. Neue Kalibrierverfahren werden entwickelt und überprüft. Durch Anwendung dieser Verfahren kann die Oberflächentemperatur der Prüflinge hoch genau bestimmt werden. Anhand der mit den neuen Verfahren bestimmten Verteilung der Oberflächentemperatur und weiteren aerodynamischen Messungen werden abschließend Empfehlungen formuliert, wie ein auf Drallkühlung basierendes Kühlsystem für Turbinenrotorschaufeln leistungsfähiger werden kann und so die geforderte Lebensdauer dieser Bauteile sicherstellen kann.

This book presents a historical and philosophical analysis of programming systems, intended as large computational systems like, for instance, operating systems, programmed to control processes. The introduction to the volume emphasizes the contemporary need of providing a foundational analysis of such systems, rooted in a broader historical and philosophical discussion. The different chapters are grouped around three major themes. The first concerns the early history of large systems developed against the background of issues related to the growing semantic gap between hardware and code. The second revisits the fundamental issue of complexity of large systems, dealt with by the use of formal methods and the development of `grand designs'like Unix. Finally, a third part considers several issues related to programming systems in the real world, including chapters on aesthetical, ethical and political issues. This book will interest researchers from a diversityof backgrounds. It will appeal to historians, philosophers, as well as logicians and computer scientists who want to engage with topics relevant to the history and philosophy of programming and more specifically the role of programming systems in the foundations of computing.

In einem Solarturmkraftwerk werden hunderte bis tausende Spiegel (sogenannte Heliostate) einzeln der Sonne nachgeführt, sodass das Sonnenlicht auf die Spitze eines Turmes konzentriert wird. Dort befindet sich der Receiver, der die Solarstrahlung absorbiert und an das Wärmeträgermedium weitergibt. Große thermische Energiespeicher erlauben die ganztägige Stromproduktion (auch Nachts). In aktuellen Solarturmkraftwerken kommen als Wärmeträger- und Speichermedium häufig flüssige Nitratsalze wie Solar Salt zum Einsatz. Aufgrund ihrer hohen Wärmekapazität und den geringen Kosten eignen sie sich sehr gut zur thermischen Energiespeicherung, jedoch bringen sie auch einige Nachteile mit sich. Flüssigmetalle weisen in vielen Punkten Vorteile gegenüber den Flüssigsalzen auf. In der vorliegenden Arbeit werden die Eigenschaften von Flüssigmetallen detailliert analysiert und mit Solar Salt verglichen. Zur Bewertung werden die Jahreserträge bzw. die Stromgestehungskosten (LCOE) herangezogen. Die Ergebnisse zeigen ein Potenzial zur Reduktion der Stromgestehungskosten mit Flüssigmetallen um bis zu 16% gegenüber dem Referenzsystem mit Solar Salt, ohne dabei den Kraftwerksblock und den thermischen Speicher zu verändern.

This book is open access under a CC BY 4.0 license.This book focuses on the global cycles of energy, water and carbon, which are not only the essentials of our main energy carriers, the fossil fuels, but are also the building blocks of life. The book offers an overview of the basic scientific facts and relationships that are needed to understand today's energy generation and use, how they relate to global climate, the water cycle and other resources, and the complexities of energy policy. Building on the work of the Desertec project, it presents the main technological options that we will have in a world after the “Energiewende” and presents the possible future solutions for a sustainable world. The book is written in an engaging, descriptive style that can be understood by those without specific knowledge of science or economics and allows readers to form their own conclusions. Controversy rages over energy problems, climate change and their possiblesolutions. Expressions like “climate deniers”, “renaissance of nuclear energy”, “stop the war on coal”, and “Energiewende now” represent a diversity of opinions that divide our society and political leaders. This book shows the reader the whole energy picture and how it is part of the wider global problems of overpopulation and uncontrolled economies in a world of limited resources.

This book brings together formally disparate literatures and debates on disability and technology in a way that captures the complex interplay between the two. Drawing on disability studies, technology studies and clinical studies, the book argues that interdisciplinary insights together provide a more nuanced and less stylized picture of the benefits and barriers in disability and technology.Drawing on a breadth of empirical studies from across the globe, a picture emerges of the complex and multi-directional interplay of technology and disability. Technology is neither inherently enabling or disabling but fundamentally shaped by the social dynamics that shape their design, use and impact.

Facing Heidegger's critique of modern technology, the author analyses the question of technology and ethical responsibility and the call for reflexivity towards technology. He examines Heidegger‘s thoughts about how science and technology conceal the enigmatic and distinctive presencing of Being and exhibits how modern technology has brought unintended consequences and risks. The author extends the deliberation among diverse epistemologies, interested parties and laypersons, a component of reflexive modernization. Such epistemic community opens the way for a new reflexive democratization of technology, in which different actors should be involved in decision making about technology as it affects the society, the environment and individuals.

This edited volume explores the interplay between philosophies in a wide-ranging analysis of how technological applications in science inform our systems of thought. Beginning with a historical background, the volume moves on to explore a host of topics, such as the uses of technology in scientific observations and experiments, the salient relationship between technology and mechanistic notions in science and the ways in which today's vast and increasing computing power helps scientists achieve results that were previously unattainable.Technology allows today's researchers to gather, in a matter of hours, data that would previously have taken weeks or months to assemble. It also acts as a kind of metaphor bank, providing biologists in particular with analogies (the heart as a ‘pump', the nervous system as a ‘computer network') that have become common linguistic currency. This book also examines the fundamental epistemological distinctions between technology and science and assesses their continued relevance. Given the increasing amalgamation of the philosophies of science and technology, this fresh addition to the literature features pioneering work in a promising new field that will appeal both to philosophers and scientific historiographers.

A visionary and optimistic thinker examines the tension between privacy and publicness that is transforming how we form communities, create identities, do business, and live our lives.Thanks to the internet, we now live—more and more—in public. More than 750 million people (and half of all Americans) use Facebook, where we share a billion times a day. The collective voice of Twitter echoes instantly 100 million times daily, from Tahrir Square to the Mall of America, on subjects that range from democratic reform to unfolding natural disasters to celebrity gossip. New tools let us share our photos, videos, purchases, knowledge, friendships, locations, and lives.Yet change brings fear, and many people—nostalgic for a more homogeneous mass culture and provoked by well-meaning advocates for privacy—despair that the internet and how we share there is making us dumber, crasser, distracted, and vulnerable to threats of all kinds. But not Jeff Jarvis.In this shibboleth-destroying book, Public Parts argues persuasively and personally that the internet and our new sense of publicness are, in fact, doing the opposite. Jarvis travels back in time to show the amazing parallels of fear and resistance that met the advent of other innovations such as the camera and the printing press. The internet, he argues, will change business, society, and life as profoundly as Gutenberg's invention, shifting power from old institutions to us all.Based on extensive interviews, Public Parts introduces us to the men and women building a new industry based on sharing. Some of them have become household names—Facebook's Mark Zuckerberg, Google's Eric Schmidt, and Twitter's Evan Williams. Others may soon be recognized as the industrialists, philosophers, and designers of our future. Jarvis explores the promising ways in which the internet and publicness allow us to collaborate, think, ways—how we manufacture and market, buy and sell, organize and govern, teach and learn. He also examines the necessity as well as the limits of privacy in an effort to understand and thus protect it. This new and open era has already profoundly disrupted economies, industries, laws, ethics, childhood, and many other facets of our daily lives. But the change has just begun. The shape of the future is not assured. The amazing new tools of publicness can be used to good ends and bad. The choices—and the responsibilities—lie with us. Jarvis makes an urgent case that the future of the internet—what one technologist calls “the eighth continent”—requires as much protection as the physical space we share, the air we breathe, and the rights we afford one another. It is a space of the public, for the public, and by the public. It needs protection and respect from all of us. As Secretary of State Hillary Clinton said in the wake of the uprisings in the Middle East, “If people around the world are going to come together every day online and have a safe and productive experience, we need a shared vision to guide us.” Jeff Jarvis has that vision and will be that guide.

This book follows the fraught attempts of engineers to identify with Korea as a whole. It is for engineers, both Korean and non-Korean, who seek to become better critical analysts of their own expertise, identities, and commitments. It is for non-engineers who encounter or are affected by Korean engineers and engineering, and want to understand and engage them. It is for researchers who serve as critical participants in the making of engineers and puzzle over the contents and effects of techno-national formation.

“Nobody knows better than Bruce Sterling how thin the membrane between science fiction and real life has become, a state he correctly depicts as both thrilling and terrifying in this frisky, literate, clear-eyed sketch of the next half-century. Like all of the most interesting futurists, Sterling isn't just talking about machines and biochemistry: what he really cares about are the interstices of technology with culture and human history.” -Kurt Andersen, author of Turn of the CenturyVisionary author Bruce Sterling views the future like no other writer. In his first nonfiction book since his classic The Hacker Crackdown, Sterling describes the world our children might be living in over the next fifty years and what to expect next in culture, geopolitics, and business.Time calls Bruce Sterling “one of America's best-known science fiction writers and perhaps the sharpest observer of our media-choked culture working today in any genre.” Tomorrow Now is, as Sterling wryly describes it, “an ambitious, sprawling effort in thundering futurist punditry, in the pulsing vein of the futurists I've read and admired over the years: H. G. Wells, Arthur C. Clarke, and Alvin Toffler; Lewis Mumford, Reyner Banham, Peter Drucker, and Michael Dertouzos. This book asks the future two questions: What does it mean? and How does it feel? ”Taking a cue from one of William Shakespeare's greatest soliloquies, Sterling devotes one chapter to each of the seven stages of humanity: birth, school, love, war, politics, business, and old age. As our children progress through Sterling's Shakespearean life cycle, they will encounter new products; new weapons; new crimes; new moral conundrums, such as cloning and genetic alteration; and new political movements, which will augur the way wars of the future will be fought. Here are some of the author's predictions:• Human clone babies will grow into the bitterest and surliest adolescents ever.• Microbes will be more important than the family farm.• Consumer items will look more and more like cuddly, squeezable pets.• Tomorrow's kids will learn more from randomly clicking the Internet than they ever will from their textbooks.• Enemy governments will be nice to you and will badly want your tourist money, but global outlaws will scheme to kill you, loudly and publicly, on their Jihad TVs.• The future of politics is blandness punctuated with insanity. The future of activism belongs to a sophisticated, urbane global network that can make money—the Disney World version of Al Qaeda.Tomorrow Now will change the way you think about the future and our place in it.From the Hardcover edition.

Technik ist allgegenwärtig. Sie durchdringt nicht nur die Produktion von Gütern und die Wissenschaften, auch unser Alltagsleben ist weitgehend durchwebt mit technischen Anordnungen unterschiedlichster Form und Ausprägung. Dabei ist den einzelnen technischen Artefakten häufig nicht anzusehen, wie stark sie nicht nur unsere Umwelt beeinflussen, sondern sogar unser Erkennen und Verstehen mitprägen. Dieser Zirkel von Verstehen und Gestalten, Gestalten und Verstehen kann als ein hermeneutischer Zirkel der Technik beschrieben werden. Die Beiträge des Sammelbandes setzen sich in diesem Sinne mit Aspekten einer philosophischen Begründung von technischem Handeln auseinander, versuchen verschiedene Deutungen etablierter Wissenschaften zu hinterfragen und geben Aussichten auf mögliche Gestaltungsansätze. Technik wird dabei nicht als dem Menschen gänzlich äußerlich und entgegengesetzt begriffen, sondern als ihm wesentlich inhärent – als Teil verständnisorientierten Handelns und handlungsorientierten Verstehens.

“Acceptable Risk” – On the Rationality (and Irrationality) of Emotional Evaluations of Risk What is “acceptable risk”? That question is appropriate in a number of different contexts, political, social, ethical, and scienti c. Thus the question might be whether the voting public will support a risky proposal or project, whether people will buy or accept a risky product, whether it is morally permissible to pursue this or that potentially harmful venture, or whether it is wise or prudent to test or try out some possibly dangerous hypothesis or product. But complicating all of these queries, the “sand in the machinery” of rational decision-making, are the emotions. It is often noted (but too rarely studied) that voters are swayed by their passions at least as much as they are convinced by rational arguments. And it is obvious to advertisers and retailers that people are seduced by all sorts of appeals to their vanities, their fears, their extravagant hopes, their insecurities. At least one major thread of ethical discourse, the one following Kant, minimizes the importance of the emotions (“the inclinations”) in favor of an emphatically rational decision-making process, and it is worth mulling over the fact that many of those who do not accept Kant's ethical views more or less applaud his rejection of the “moral sentiment theory” of the time, promoted by such luminary philosophers as David Hume and Adam Smith.

human practices? How are we to morally evaluate technology developments that have open horizons, encompass uncertainties, and lack control? Technology is in- uential on society; technological innovations act upon the perception of ourselves, the world, and our relation with fellow humans and other objects. Technology is changing everything we do by creating new entities (such as software, nanop- ticles, or Internet), by changing the scale of activities (e. g. vast amounts of data about people can be stored and analysed, and not infrequently without people - ing aware of this), by generating new kinds of knowledge (for instance about i- nesses, the human genome and so on). Technologies, as a consequence, impinge upon our morality and for this reason an ethics of technology should not wait passively until moral problems arise and not only focus on identi ed and exi- ing moral problems, but contemplate technology developments and possible - pacts proactively. However, this is easier said than done, because a prospective and proactive evaluation of technology developments is complicated by complexity and uncertainty. The uncertainty of technology development is closely related to one of the str- ing features of technology, namely what Jim Moor has coined logical malleability. (1985, 269) Technological devices are logically malleable in that they can be shaped to do any activity that can be characterised in terms of logical operations.
