Die Möglichkeiten der Wissensvermittlung über eingebettete Systeme haben sich durch das erforderliche distance learning stark verändert. Die bekannten didaktischen Konzepte, welche bis dahin angewandt wurden, werden durch den Wegfall von Präsenz-Praktika und den fehlenden Zugang zu einem IoT- Labor ausgehebelt.
Diese Master-Thesis beschäftigt sich daher mit der Idee, wie eine Überholung des Eingebettete Systeme-Moduls an der Hochschule Ruhr West sowohl die Modulziele weiter erfüllen kann als auch darüber hinaus einen Mehrwert erschaffen wird. Vor diesem Hintergrund wird untersucht wie durch die Einführung eines Remote-Labs in Kombination mit einer kollaborativen Entwicklungssoftware für Lerngruppen, Anreize für die Studierenden geschaffen werden können, die ihnen praxisnäheres und fundiertes Wissen in der Entwicklung eingebetteter Systeme vermitteln.
Dieses neue Vorgehen verwendet einen Peer-Group-Code-Bearbeitung- Ansatz in Echtzeit und Peer-to-Peer-Videokonferenzen und verteilt über den MQTT-Server die Interaktion der Hardwareentwicklung als integralen Bestandteil eines Kurskonzepts. Ziel ist es, die Motivation und die Lernleistung der Schüler zu verbessern.
Das Vorgehen wird anhand begleitender Umfragen während des Moduls weiterentwickelt und die Semesterergebnisse werden unter Zuhilfenahme von Bewertungskriterien mit denen vergangener Jahre verglichen. Darüber hinaus wird das neue Kurskonzept durch eine Expertenbefragung in Form von Studierenden evaluiert, welche den Kurs in seiner alten Form durchlaufen haben.

So far, researchers have used a wellbeing-centered approach to catalyze successful intergenerational collaboration (IGC) in innovative activities. However, due to the subject’s multidisciplinary nature, there is still a dearth of comprehensive research devoted to constructing the IGC system. Thus, the purpose of this study is to fill a research void by providing a conceptual framework for information technology (IT) system designers to use as a jumping-off point for designing an IGC system with a wellbeing-oriented design. A systematic literature study was conducted to identify relevant terms and develop a conceptual framework based on a review of 75 selected scientific papers. The result consists of prominent thematic linkages and a conceptual framework related to design technology for IGC systems. The conceptual framework provides a comprehensive overview of IGC systems in the innovation process by identifying five barrier dimensions and using six wellbeing determinants as IGC catalysts. Moreover, this study discusses future directions for research on IGC systems. This study offers a novel contribution by shifting the technology design process from an age-based design approach to wellbeing-driven IGC systems. Additional avenues for investigation were revealed through the analysis of the study’s findings.
This study proposes a framework for the collaborative development of global start-up innovators in a multigenerational digital environment. Intergenerational collaboration has been identified as a strategy to support entrepreneurs during their formative years. However, integrating and fostering intergenerational collaboration remains elusive. Therefore, this study aims to identify competencies for successful global start- ups through intergenerational knowledge transfer. We used a systematic literature review to identify a competency set consisting of growth virtues, effectual creativity, technical domain, responsive teamwork, values-based organization, sustainable networking, cultural awareness, and facilitating intergenerational safety. The competency framework serves as a foundation for knowledge management research on the global innovation readiness of people to collaborate across generations in the digital age.
This study aims to determine the competing concerns of people interested in startup development and entrepreneurship by using topic modeling and sentiment analysis on a social question-and-answer (SQA) website. Understanding the underlying concerns of startup entrepreneurs is critical to society and economic growth. Therefore, greater scientific support for entrepreneurship remains necessary, including data mining from virtual social communities. In this study, an SQA platform was used to identify the sentiment of thirty concerns of people interested in startup entrepreneurship. Based on topic modeling and sentiment analysis of 18819 inquiries in various forums on an SQA, we identified additional questions about founder figures, keys to success, and the location of a startup. In addition, we found that general questions were rated more positively, especially when it came to pitching, finding good sources, disruptive innovation, idea generation, and marketing advice. On average, the identified concerns were considered 48.9 percent positive, 41 percent neutral, and 10.1 percent negative. This research establishes a critical foundation for future research and development of digital startups by outlining a variety of different concerns associated with startup development in the digital age.
Ziel dieser Arbeit ist es, eine deutlich definierte Markenidentität für DigiCerts zu konzipieren. Zu diesem Zweck wird das Markensteuerrad von Esch (2018, S.98) angewandt, um in detaillierten Schritten eine nützliche Markenidentität aufzubauen. Mithilfe dieser soll anschließend folgende Fragestellung beantwortet werden: Wie kann sich DigiCerts in der Hochschullandschaft positionieren? Zur Beantwortung der zugrunde liegenden Frage, wird die Positionierungspyramide von Esch(2009, S. 163)genutzt.
Insgesamt soll mithilfe dieser Arbeit eine für DigiCerts anwendbare Identität aufgebaut werden.
The goal of this empirical study is to answer whether predictions about stock price movements can be made with the use of machine learning in the energy sector and what influence contributions from social media have on its development. To answer the research
question, the social media platforms Twitter and Reddit, in terms of the suitability of the information, were studied and evaluated. Then, the sentiments of the posts from social media were collected and used in machine learning models. The models include the Gradient Boosted Regression Tree, Multilayer Perceptron, and Long Short-Term
i Memory, which predict a subsequent day's closing stock price. The study showed that deviations from predictions of stock price movements of 1.05 % are possible and further sentiment values do not show significant positive effect on reducing the error value. The
result shows that the collected sentiments from the social media platform Twitter have no positive effect on the stock price movements within the energy industry.
