Working in collaborative groups and teams now represents the practice predominantly adopted by organizations aspiring to create innovation. However, this trend towards boundless collaboration at work is harshly criticized for a resulting discrimination of introverted employees - called the New Groupthink. According to this, introverts suffer from working conditions that inhibit individual and quiet work. The current shift towards collaboration overall elicits lower creativity and achievement levels due to the resulting suppression of introverts. This inefficiency hence depicts a relevant issue for companies by reason of creativity and innovation's decisive stake in todays' turbulent environments. Therefore, this quantitative research investigates whether hybrid brainstorming can equate introverts with extraverts by balancing their idea contribution. It suggests solutions to both introverts, with regards to enhancing their stake in ideation, and companies, with regards to how to apply ideation methods in most efficient ways.

Führungskräfte in der öffentlichen Verwaltung spielen bei der Prävention von Korruption eine entscheidende Rolle. Um das Thema in die Verwaltungskultur zu implementieren, sollten die Verwaltungsprozesse berücksichtigt, Schwachstellen klar erkannt und die Beschäftigten beteiligt werden.

Without any doubt, creating links and navigational trails is fundamental to hypertext. The Web is the widest spread representative among all systems in the history of hypertext, although its underlying core concept is kept simple. This is why the Web's widely used link functionality is naive, supporting only embedded, unary and unidirectional links. A strength of the Web is its extensibility, giving us the opportunity to augment the current functionality of links. We showcase a browser plugin, which enables users to create and share complex links over the existing Web. Furthermore, we discuss the CB-OHS Mother, its link model and how this relates to existing work. The implementation adopts latest standardization efforts and is an update to older attempts of enabling external link services for the Web.

Machines in processing plants are frequently generating failures that must be manually fixed by the operators. Machines often lack advanced assistance systems for to address these failure cases. While some new developments try to use only machine data, in many applications, the human knowledge of the operators can be very useful. In this paper, we propose a new assistance system used to merge machine data with the operator’s knowledge. This system is tested with an industry partner. The test results are used to create design considerations, compare different reasoning algorithms, and check the influence on the machine downtime.

Since its launch in 2008, the Android platform has seen a lot of development and improvements to this day. Android developer studios had to refine their understanding and available codebases considerably in the past decade since Android’s conception. For example, they had to handle monumental changes in the OS, like the introduction of ART or the continually evolving permission system. With this study, we look into the code-base of 1,250 apps from 57 different development studios and analyze the evolution of security-related issues in past versions of an app. To analyze a total of 11,002 APKs, we build on popular vulnerability assessment tools like QARK and drozer and extend them with our own security checks. We discover that the attack surface of an app usually grows over time, including issues that are open for a long time or remain unclosed. Considering the false positive rate of automated vulnerability scanners like QARK or drozer, the total number of vulnerabilities in an app must be taken with care, but nevertheless our study substantiates that the number of security issues typically grows with code complexity and size, rather than shrinking over time.
