Digitale Bürgerbeteiligung
€ 32.99 *
ggf. zzgl. Versand

Bürgerbeteiligung, d. h. die Beteiligung der Bürgerinnen und Bürger an politischen Planungsprozessen oder Entscheidungen, wird bereits in Deutschland, Österreich und der Schweiz gefördert und gelebt. In Zeiten der Digitalisierung werden immer häufiger technische Applikationen zur elektronischen Partizipation (E-Partizipation) eingesetzt. Die Nutzung von Technologien bietet Chancen und Herausforderungen gleichermaßen, so zum Beispiel in den Bereichen Sicherheit, Datenschutz und nutzerorientierte Gestaltung. Das Buch greift genau diese Themen im Bereich der E-Partizipation auf und erläutert insbesondere Gestaltungsaspekte der digitalen Bürgerbeteiligung. Es kombiniert aktuelle Forschungsergebnisse mit bestehenden Theorien der E-Partizipation und bietet eine umfassende, interdisziplinäre Analyse aus sozialwissenschaftlicher, rechtlicher und technologischer Perspektive. Schutz der Privatsphäre und Sicherheit sind dabei zentrale Aspekte des Buches, die langfristig das Vertrauen in digitale Bürgerbeteiligung fördern können.

Discrete Charm of the Machine
€ 22.99 *
ggf. zzgl. Versand

A few short decades ago we were informed by the smooth signals of analog television, radio, and vinyl discs; communicated with our analog telephones; and even computed with analog computers. Today our world is digital, built with zeros and ones. Why did this revolution occur? The Discrete Charm of the Machine explains, in an engaging and accessible manner, the varied physical and logical reasons behind this radical transformation. The spark of individual genius shines through this story of innovation: the stored program of Jacquard´s loom; the logical branching of Charles Babbage; Alan Turing´s brilliant abstraction of the discrete machine; Harry Nyquist´s foundation for digital signal processing; Claude Shannon´s breakthrough insights into the meaning of information and bandwidth; and Richard Feynman´s prescient proposals for nanotechnology and quantum computing. Ken Steiglitz follows the progression of these ideas in the building of our digital world, from the internet and artificial intelligence to the edge of the unknown. Are questions like the famous traveling salesman problem truly beyond the reach of ordinary digital computers? Can quantum computers transcend these barriers? Does a mysterious magical power reside in the analog mechanisms of the brain? Steiglitz concludes by confronting the moral and aesthetic questions raised by the development of artificial intelligence and autonomous robots.

The Theory and Practice of Social Machines
€ 98.99 *
ggf. zzgl. Versand

Social machines are a type of network connected by interactive digital devices made possible by the ubiquitous adoption of technologies such as the Internet, the smartphone, social media and the read/write World Wide Web, connecting people at scale to document situations, cooperate on tasks, exchange information, or even simply to play. Existing social processes may be scaled up, and new social processes enabled, to solve problems, augment reality, create new sources of value, and disrupt existing practice. This book considers what talents one would need to understand or build a social machine, describes the state of the art, and speculates on the future, from the perspective of the EPSRC project SOCIAM - The Theory and Practice of Social Machines. The aim is to develop a set of tools and techniques for investigating, constructing and facilitating social machines, to enable us to narrow down pragmatically what is becoming a wide space, by asking ´when will it be valuable to use these methods on a sociotechnical system?´ The systems for which the use of these methods adds value are social machines in which there is rich person-to-person communication, and where a large proportion of the machine´s behaviour is constituted by human interaction.
