Scholarship in the Digital Age: Information, Infrastructure, and the Internet (The\mit Press Ser.)
by Christine L. BorgmanAn exploration of the technical, social, legal, and economic aspects of the scholarly infrastructure needed to support research activities in all fields in the twenty-first century.Scholars in all fields now have access to an unprecedented wealth of online information, tools, and services. The Internet lies at the core of an information infrastructure for distributed, data-intensive, and collaborative research. Although much attention has been paid to the new technologies making this possible, from digitized books to sensor networks, it is the underlying social and policy changes that will have the most lasting effect on the scholarly enterprise. In Scholarship in the Digital Age, Christine Borgman explores the technical, social, legal, and economic aspects of the kind of infrastructure that we should be building for scholarly research in the twenty-first century.Borgman describes the roles that information technology plays at every stage in the life cycle of a research project and contrasts these new capabilities with the relatively stable system of scholarly communication, which remains based on publishing in journals, books, and conference proceedings. No framework for the impending “data deluge” exists comparable to that for publishing. Analyzing scholarly practices in the sciences, social sciences, and humanities, Borgman compares each discipline's approach to infrastructure issues. In the process, she challenges the many stakeholders in the scholarly infrastructure—scholars, publishers, libraries, funding agencies, and others—to look beyond their own domains to address the interaction of technical, legal, economic, social, political, and disciplinary concerns. Scholarship in the Digital Age will provoke a stimulating conversation among all who depend on a rich and robust scholarly environment.

Schools and Schooling in the Digital Age: A Critical Analysis (Foundations and Futures of Education)
by Neil SelwynThis book presents a wide-ranging and critical exploration of a topic that lies at the heart of contemporary education. The use of digital technology is now a key feature of schools and schooling around the world. Yet despite its prominence, technology use continues to be an area of education that rarely receives sustained critical attention and thought, especially from those people who are most involved and affected by it. Technology tends to be something that many teachers, learners, parents, policy-makers and even academics approach as a routine rather than reflective matter. Tackling the wider picture, addressing the social, cultural, economic, political and commercial aspects of schools and schooling in the digital age, this book offers to make sense of what happens, and what does not happen, when the digital and the educational come together in the guise of schools technology. In particular, the book examines contemporary schooling in terms of social justice, equality and participatory democracy. Seeking to re-politicise an increasingly depoliticised area of educational debate and analysis, setting out to challenge the many contradictions that characterise the field of education technology today, the author concludes by suggesting what forms schools and schooling in the digital age could, and should, take. This is the perfect volume for anyone interested in the application and use of technology in education, as well as the education policy and politics that surround it; many will also find its innovative proposals for technology use an inspiration for their own teaching and learning.
Schools and Screens: A Watchful History
by Victoria CainWhy screens in schools—from film screenings to instructional television to personal computers—did not bring about the educational revolution promised by reformers.Long before Chromebook giveaways and remote learning, screen media technologies were enthusiastically promoted by American education reformers. Again and again, as schools deployed film screenings, television programs, and computer games, screen-based learning was touted as a cure for all educational ills. But the transformation promised by advocates for screens in schools never happened. In this book, Victoria Cain chronicles important episodes in the history of educational technology, as reformers, technocrats, public television producers, and computer scientists tried to harness the power of screen-based media to shape successive generations of students. Cain describes how, beginning in the 1930s, champions of educational technology saw screens in schools as essential tools for training citizens, and presented films to that end. (Among the films screened for educational purposes was the notoriously racist Birth of a Nation.) In the 1950s and 1960s, both technocrats and leftist educators turned to screens to prepare young Americans for Cold War citizenship, and from the 1970s through the 1990s, as commercial television and personal computers arrived in classrooms, screens in schools represented an increasingly privatized vision of schooling and civic engagement. Cain argues that the story of screens in schools is not simply about efforts to develop the right technological tools; rather, it reflects ongoing tensions over citizenship, racial politics, private funding, and distrust of teachers. Ultimately, she shows that the technologies that reformers had envisioned as improving education and training students in civic participation in fact deepened educational inequities.
Schulische Kabinettprojektion: Räumliches Zeichnen im Raster (essentials)
by Berthold HeinrichBerthold Heinrich stellt die mathematischen und zeichnerischen Grundlagen für die Darstellung von Objekten im Raum auf kariertem Papier vor. Dabei präsentiert er auch die Nutzung von Software. In der Schule wird oft kariertes Papier als Raster zur Darstellung von Flächen und Körpern genutzt. Allerdings werden, selbst in einigen Druckwerken, z. B. die entstehenden Ellipsen und Winkelbögen ungenau gezeichnet oder eine Kugelkontur falsch als Kreis dargestellt. Im vorliegenden Essential werden die korrekten Verfahren sowohl theoretisch als auch an konkreten Beispielen vorgestellt und können meist direkt umgesetzt werden. Einige aufwändigere Abläufe stellt der Autor anschaulich an Beispielen dar.

Schutz genetischer, medizinischer und sozialer Daten als multidisziplinäre Aufgabe
by Stefan Katzenbeisser Kay Hamacher Heribert M. AnzingerFortschritte in der Medizin, in der Genomforschung und in der Informationstechnik stellen den Datenschutz vor ein Dilemma: Forschung und die Anwendung neuer Methoden setzen häufig voraus, dass personenbezogene Daten in großem Umfang zentral verfügbar, verteilbar und verknüpfbar sind. Gleichzeitig bergen zentrale Datensammlungen und die unübersehbare Weitergabe und Verknüpfung sensitiver Daten die Gefahr, dass der Einzelne auf ein Datenraster reduziert wird und Selbstbestimmungsmöglichkeiten verliert. Den Wertungskonflikten und der Schutzbedürftigkeit und Schutzfähigkeit personenbezogener genetischer, medizinischer und sozialer Daten widmete sich eine multidisziplinäre Veranstaltungsreihe des Center for Advanced Security Research Darmstadt, der Darmstädter Juristischen Gesellschaft und der Fakultät für Rechts- und Wirtschaftswissenschaften der Technischen Universität Darmstadt. Der vorliegende Band fasst die dabei entwickelten Gedanken verschiedener Wissenschaftsdisziplinen zusammen.

Science Fiction and Innovation Design
by Thomas MichaudScience fiction is often presented as a source of utopia, or even of prophecies, used in capitalism to promote social, political and technoscientific innovations. Science Fiction and Innovation Design assesses the validity of this approach by exploring the impact this imaginary world has on the creativity of engineers and researchers. Companies seek to anticipate and predict the future through approaches such as design fiction: mobilizing representations of science fiction to create prototypes and develop scenarios relevant to organizational strategy. The conquest of Mars or the weapons of the future are examples developed by authors to demonstrate how design innovation involves continuous dialogue between multiple players, from the scientist to the manager, through to the designers and the science fiction writers.
