Im digitalen Zeitalter wird Kommunikation zu einer zentralen Ressource der Kriegsführung, wie der Russland-Ukraine-Konflikt zeigt: Die Kriegsparteien bedienen sich modernster Methoden strategischer Kommunikation, um den politischen und öffentlichen Diskurs in ihrem Sinne zu beeinflussen. In diesem "Krieg der Narrative" prallen widersprüchliche Sichtweisen aufeinander. Das stellt nicht nur das Publikum, sondern auch den qualitätsorientierten Journalismus vor besondere Herausforderungen - bei der Berichterstattung über die Kämpfe aus den Kriegsgebieten, bei der Faktenprüfung und beim Quellenabgleich ebenso wie bei der Visualisierung der Berichte und Reportagen. Nicht nur die Kriegsparteien, auch der Kriegs- und Krisenjournalismus rüsten daher kommunikativ auf - etwa im Hinblick auf den Einsatz von Systemen der Künstlichen Intelligenz oder der Virtuellen Realität. Expert/-innen aus Wissenschaft und Journalismus widmen sich in diesem Band ausführlich den Strategien und Methoden der Kriegskommunikation. Dabei analysieren sie das Vorgehen der ukrainischen und russischen Regierungen, aber auch die Kriegsberichterstattung und deren Wirkungen auf die Öffentlichkeit, die von Zweifeln an der journalistischen Objektivität oder einem nachlassenden Interesse geprägt sind.

In this ever-evolving world of technology, where cloud computing, machine learning, and IoT are the talk of the town, it's easy to forget the stalwarts that keep our digital world running smoothly. Among these unsung heroes of the IT world, the mainframe computer holds a special place. Despite the onset of newer technologies, mainframes continue to be the backbone of many industries, handling a significant portion of the world's business transactions.SOAP, or Simple Object Access Protocol, has been pivotal in allowing mainframes to communicate effectively with the digital universe. By using SOAP, mainframes can provide their robust and reliable services over the network to clients, regardless of the client's platform or language. In an era where interoperability is key, SOAP's role in mainframe architecture is more critical than ever.This book, "Mastering SOAP in Mainframes: A Comprehensive Guide to Web Services in Enterprise Computing," is designed to illuminate the essential role of SOAP in mainframe environments. The aim is to provide a practical guide to professionals who are working, or aspiring to work, with mainframe SOAP services.
