¿This book follows a Goffmanian approach to self-presentation to focus on the different strategies Spanish users employ to construct their digital identity in profiles, biographies, pictures, and statuses on platforms such WhatsApp, Twitter, Facebook, Instagram and LinkedIn. The author presents a functioning taxonomy of self-presentation strategies along the front-stage/back-stage continuum, including common strategies such as eudaimonic (or inspirational) messages and the use of humour. Special attention is paid to the effects of social variables such as the users' gender and age, and the perceived purposes of the different platforms (e.g. LinkedIn is often intended as a professional market for job hunting, whereas Facebook is rarely used in this context). The book will be of interest to students and scholars of Technologically Mediated Communication (traditionally known as Computer-Mediated Communication or CMC), media communication, internet pragmatics, digital discourse analysis, and related fields.

Für den stabilen und sicheren Betrieb des Internets ist die US-amerikanische gemeinnützige Organisation Internet Corporation for Assigned Names and Numbers (ICANN) verantwortlich, wozu die Koordination der Vergabe von Domain-Namen gehört. Die Europäische Datenschutz-Grundverordnung (EU-DSGVO) dient der Vereinheitlichung des Datenschutzrechts und schützt die Verarbeitung von personenbezogenen Daten. Dies hat einen Einfluss auf die öffentlich zugänglichen Informationen von registrierten Domain-Namen, deren Veröffentlichung die ICANN in ihren Richtlinien vorschreibt. Diese Informationen umfassen personenbezogene Daten wie den Namen, die Postanschrift und die E-Mail-Adresse der Domain-innehabenden Person. Die ICANN änderte ihre Richtlinien, jedoch ist weiterhin die Veröffentlichung dieser Angaben möglich. In dem vorliegenden Buch werden die Auswirkungen der EU-DSGVO auf das E-Mail-Marketing und die Verwendung von E-Mail-Adressen für E-Mail-Kampagnen untersucht, insbesondere in Bezug aufunerwünschte E-Mail-Werbung. Dazu wird die folgende Forschungsfrage gestellt: Welchen Effekt hat die Veröffentlichung der E-Mail-Adresse der Domain-innehabenden Person in den WHOIS-Datenbanken auf die Anzahl eingehender unerwünschter Marketing-E-Mails?

Die Digitalisierung eröffnet neue Chancen für Bildung: Doch wie entstehen digitale Lernangebote, die Lernerfahrungen eröffnen und zu Lernerfolgen beitragen? Das Thema E-Learning war lange Zeit ein Nischenthema für spezielle Anliegen. Spätestens mit der Corona-Pandemie sind Bildungstechnologien zu einem zentralen Thema avanciert, das alle Lehrenden und Bildungsverantwortlichen beschäftigt. Digitales Lernen ist ein selbstverständlicher Bestandteil von Lernarrangements, die verschiedene mediale und methodische Elemente integrieren, um Lernen flexibel anzulegen und der Vielfalt der individuellen Voraussetzungen entgegenzukommen. In jedem Bildungskontext und in allen Altersgruppen ist zu überlegen, wie und mit welchen digitalen Elementen ein Lernangebot profitieren kann. Die Chancen des digitalen Lernens lassen sich dabei nur mit einem didaktischen Design einlösen, das auf einer Analyse der didaktischen Parameter aufsetzt und erkennbar werden lässt, wie es zur Lösung eines identifizierten Bildungsproblems beiträgt. Das Buch führt ein in die Grundlagen des Lehrens und Lernens mit digitalen Medien und beschreibt die Vorgehensweise des didaktischen Designs bei der Konzeption digitaler Lernangebote.

This project was motivated by the upcoming fiftieth anniversary of the IFIP Human Choice and Computers (HCC) conference, the event that led to IFIP¿s Technical Committee 9 (TC 9). Although IFIP committees are mainly technical, TC 9 is dedicated to research at the intersection of information and communication technology (ICT) with society. In addition to sponsoring HCC, TC 9 supports groups that have specific research interests. In consultation with their members, the leaders of each group offer chapters about their groups¿ history and goals. An additional chapter describes TC 9¿s formation, and an appendix details the national groups that work closely with TC 9. Overall, this volume is a useful guide to the historical development of research on ICT and society, providing readers with important reference works and relevant themes, and also points to likely new trends in these domains.

The world population is increasing while arable land is decreasing at an alarming rate. About one-quarter of arable land is degraded and needs significant restoration before it can sustain crops again. By 2030, the water supply will fall 40% short of meeting global demand. Moreover, looming climate change poses additional challenge to increasing food production to feed 10 billion people by 2050. Current major agricultural systems are on a largely unsustainable trajectory because of their contributions to greenhouse gas emissions, water pollution, and biodiversity loss.For these reasons, innovative technologies are being introduced in modern agriculture to sustain food production. They include digital and geospatial technologies to manage soil, climate and plant genetic resources. With the development of tools and sensors integrated into the internet of things (IoT) environment, physically collected information is converted into computer-readable language. Digital innovations thus allow real-time analysis, machine learning, and artificial intelligence (AI) that manage massive amount of data, also known as big data. Accordingly, digital agriculture affords greater potential for sustainable farming and economic benefits.This book summarizes the latest advances in AI-integration of agriculture practices. Specific focus includes but not limited to, big data, yield mapping, pests management, and optimal fertigation. As such, it presents a forward-looking approach to meet multiple UN Sustainable Development Goals, specifically, SDG 2, 6, 13 and 15.

This book describes the most recent strategies for the digitalization of railway sector that bring new challenges for the construction, operation, and maintenance of railway infrastructures. These strategies involve the development and application of new technologies and methodologies to enhance the sustainability and resilience of railway infrastructures particularly under extreme climate and operational events. In particular, the digital transformation involves the use of digital twins, augmented and virtual reality, forecast capabilities, risk and life-cycle analysis, cybersecurity, unmanned technologies for monitoring and inspection, computer vision, AI, risk and disaster management, among others. Presently, the literature is lacking a contribution that provides general and foundational knowledge across these and other topics. Therefore, this book provides valuable information for researchers, students, and professionals in railway engineering that want to developtheir knowledge and skills in this field.
