Das Thema soll in einen Grenzbereich der Materialwirtschaft fuhren, der durch die tagespolitischen Ereignisse immer grossere Bedeutung fur die Unternehmung gewinnt. Naturgemass ist in einer marktorientierten Gesellschaft das verkaufs fahige Produkt da Objekt aller Anstrengungen und Leistungen. Produktion und Verkauf stehen im Blickpunkt, andere Bereiche werden als notwendig be trachtet, wahrend das Gebiet der Entsorgung innerhalb der Unternehmung zu nachst ohne besondere Beachtung bleibt. Mit zunehmender technologischer Perfektion, finanzwirtschaftlicher Beherrschung des Produktabsatzes ruckt die Guterbereitstellung zur Deckung des Bedarfs plotzlich in den Hintergrund - Schlagworte wie Konsumterror, Abfallgesell schaft u. a. kennzeichnen den Wandel - und die Frage nach der Qualitat der Produktion, nicht mehr des Produkts, gewinnt eine neue Dimension. Damit wird fur die Unternehmung die Alternative aufgezeigt, dass es nicht so sehr auf die Qualitat des Produktes ankommt, weil die Grundbedurfnisse befriedigt sind, sondern auf die Qualitat der Produktion, damit die Beeintrachtigung kleiner bleibe als der Nutzen der Bedarfsbefriedigung. Diese Uberlegungen zwingen die Unternehmung, einen Sektor ihrer Existenz sowohl in die Kosten- als auch in die Erlosbetrachtung einzubeziehen, namlich den Umweltschutz mit seinen Be reichen Luft- und Wasserbelastung, Abfallbeseitigung sowie Ruckgewinnung von Kreislaufstoffen aus der Luft, dem Wasser und den Abfallen. Eine Materialverwertung ohne Reststoffe mit einem Produktionsverfahren ohne Umweltbeeintrachtigung wird in der Zukunft keine Standortprobleme, keine negative Publizitat kennen und im Markt dadurch begunstigt sein."

Mastering NativeScript helps readers master the NativeScript framework for faster and more robust mobile app development. Mobile devices have progressed from a mere means of communication to becoming a critical business tool in recent years. People are increasingly glued to their smartphones as technology advances at breakneck speed. The significance of mobile app development cannot be overstated. And when it comes to mobile app development, NativeScript is a hot topic. NativeScript was introduced by Telerik, and it allows you to develop truly native apps for iOS and Android under a single code base using JavaScript or TypeScript, XML, and a subset of CSS. The charm of NativeScript is that it enables us to code once for multiple platforms (iOS 7.1 and Android 4.1), simultaneously sharing code amongst them while still allowing developers to add platform-specific instructions with flawless execution. As a result, you may release an app for both platforms using a single code base. NativeScript is comprised of three parts: a JavaScript (JS) virtual machine, a runtime, and a bridge module. The JS virtual machine is used for interpretation and execution of JavaScript code. The bridge module then converts the calls to platform-specific API calls and returns the outcome to the caller. NativeScript is a very appealing paradigm, and is rising in popularity as we speak. It can be used to construct practically any program, including communication apps (news and social networking), gaming applications (Chess, Tic-Tac-Toe, Pinball), and chat apps. It can also handle maps and geolocation apps. With Mastering NativeScript, learning NativeScript becomes straightforward, which will undoubtedly help readers advance their careers. The Mastering Computer Science series is edited by Sufyan bin Uzayr, a writer and educator with over a decade of experience in the computing field.
