This study explores the unique operating behavior of an alkaline water electrolysis cell equipped with an ion-solvating membrane, operated with a diluted alkaline electrolyte, specifically 1-M potassium hydroxide (1M KOH), in anode feed mode. Our investigations reveal several key insights.

This study examines the effectiveness of digital
nudging in enhancing email marketing strategies for non-profit organizations
(NPOs) involved in emergency and disaster relief (EDR). Specifically, it aims
to explore the potential of digital nudges to convert one-time and occasional donors into regular contributors. By investigating
whether, and to what extent, digital nudging can facilitate this conversion,
the research provides insights into optimizing donor engagement. Based on
literature, four digital nudges were developed and tested in a quantitative
field experiment conducted in partnership with the German emergency and
disaster relief organization, Caritas international. The findings reveal that
the phantom decoy and identity coherence nudges are particularly effective in
increasing click-through rates on recurring donation buttons in emails from
NPOs focused on EDR, highlighting their potential as tools for improving donor
retention.

Zur Frage der Bifurkation der Natur in der Mensch-Computer-lnteraktion bei digitalen Musikinstrumenten

In diesem Artikel wird die Frage gestellt, ob die von Alfred North Whitehead benannte "Bifurkation der Natur" in der Mensch-Computer-Interaction (MCI) vorkommt. Speziell geht es um die Entwicklung von Schnittstellen für digitale Musikinstrumente. Die Bedeutung des Begriffs der Bifurkation wird zunächst erläutert. Die Methode zur Beantwortung der Fragestellung erfolgt durch die Analyse, inwieweit sich die mit der Bifurkation der Natur einhergehenden Prozesse in Entwicklungsprozessen von musikalischen Interfaces wiederfinden. Das Ergebnis zeigt, dass die Bifurkation der Natur in der Entwicklung von musikalischen Interfaces zu finden ist. Daraus ergeben sich eine Reihe von Fragen, von denen einige dargelegt und mögliche Folgen diskutiert werden.

Synchronous online learning is situated in synchronous webinars, virtual classrooms, and videoconferences, in which students and teachers communicate live over the Internet across distant geographical locations. Shared virtual platforms with voice-over-IP technology and webcams are used to interact ubiquitously and synchronously in real-time. During the COVID-19 pandemic, the use of synchronous online learning environments in primary, secondary, higher, and continuous education has grown massively. In this chapter, we aim to identify design recommendations that help increase the effectiveness of synchronous online learning. First, we provide an overview of recent meta-analyses on the effectiveness of synchronous online learning compared to synchronous face-to-face and asynchronous online learning. Second, we use this empirical evidence to develop design principles that can guide teachers, trainers, and educators in designing effective synchronous online learning environments. Third, we discuss a research agenda for future studies on synchronous online learning, webinars, and videoconferences in education, and we reflect on some practical affordances, including the use of webcams and breakout rooms.

Effects of Cognitive Load Variation on Anthropomorphism During a Cooperative Human-Robot Pick-and-Place Task

This paper investigates anthropomorphism of a robot arm during a cooperative human-robot pick-and-place task, while varying cognitive load of test persons. Test persons are required to repeatedly provide a Lego brick for the robot by alternatingly putting it onto one of two trays. The robot then picks it up and puts it in front of the test person again. Cognitive load is varied by whether or not an initially given 8-digit number has to be remembered by the test person. Dimensions of anthropomorphism are acquired using the HRIES questionnaire and cognitive load is acquired using two state-of-the-art questionnaires. Results show a significant correlation of perceived sociability and animacy on mental demand and cognitive load, but only in the high load condition. It is suggested, that cognitive load should be considered during cooperative task design because resulting variations of anthropomorphism may impact cooperative task performance.
