As AI technology is increasingly used in production systems, different approaches have emerged from highly decentralized small-scale AI at the edge level to centralized, cloud-based services used for higher-order optimizations. Each direction has disadvantages ranging from the lack of computational power at the edge level to the reliance on stable network connections with the centralized approach. Thus, a hybrid approach with centralized and decentralized components that possess specific abilities and interact is preferred. However, the distribution of AI capabilities leads to problems in self-adapting learning systems, as knowledgebases can diverge when no central coordination is present. Edge components will specialize in distinctive patterns (overlearn), which hampers their adaptability for different cases. Therefore, this paper aims to present a concept for a distributed interchangeable knowledge base in CPPS. The approach is based on various AI components and concepts for each participating node. A service-oriented infrastructure allows a decentralized, loosely coupled architecture of the CPPS. By exchanging knowledge bases between nodes, the overall system should become more adaptive, as each node can “forget” their present specialization.
Since more and more production tasks are enabled by Industry 4.0 techniques, the number of knowledge-intensive production tasks increases as trivial tasks can be automated and only non-trivial tasks demand human-machine interactions. With this, challenges regarding the competence of production workers, the complexity of tasks and stickiness of required knowledge occur [1]. Furthermore, workers experience time pressure which can lead to a decrease in output quality. Cyber-Physical Systems (CPS) have the potential to assist workers in knowledge-intensive work grounded on quantitative insights about knowledge transfer activities [2]. By providing contextual and situational awareness as well as complex classification and selection algorithms, CPS are able to ease knowledge transfer in a way that production time and quality is improved significantly. CPS have only been used for direct production and process optimization, knowledge transfers have only been regarded in assistance systems with little contextual awareness. Embedding production and knowledge transfer optimization thus show potential for further improvements. This contribution outlines the requirements and a framework to design these systems. It accounts for the relevant factors.
The noble way to substantiate decisions that affect many people is to ask these people for their opinions. For governments that run whole countries, this means asking all citizens for their views to consider their situations and needs.
Organizations such as Africa's Voices Foundation, who want to facilitate communication between decision-makers and citizens of a country, have difficulty mediating between these groups. To enable understanding, statements need to be summarized and visualized. Accomplishing these goals in a way that does justice to the citizens' voices and situations proves challenging. Standard charts do not help this cause as they fail to create empathy for the people behind their graphical abstractions. Furthermore, these charts do not create trust in the data they are representing as there is no way to see or navigate back to the underlying code and the original data. To fulfill these functions, visualizations would highly benefit from interactions to explore the displayed data, which standard charts often only limitedly provide.
To help improve the understanding of people's voices, we developed and categorized 80 ideas for new visualizations, new interactions, and better connections between different charts, which we present in this report. From those ideas, we implemented 10 prototypes and two systems that integrate different visualizations. We show that this integration allows consistent appearance and behavior of visualizations. The visualizations all share the same main concept: representing each individual with a single dot. To realize this idea, we discuss technologies that efficiently allow the rendering of a large number of these dots. With these visualizations, direct interactions with representations of individuals are achievable by clicking on them or by dragging a selection around them. This direct interaction is only possible with a bidirectional connection from the visualization to the data it displays. We discuss different strategies for bidirectional mappings and the trade-offs involved. Having unified behavior across visualizations enhances exploration. For our prototypes, that includes grouping, filtering, highlighting, and coloring of dots. Our prototyping work was enabled by the development environment Lively4. We explain which parts of Lively4 facilitated our prototyping process. Finally, we evaluate our approach to domain problems and our developed visualization concepts.
Our work provides inspiration and a starting point for visualization development in this domain. Our visualizations can improve communication between citizens and their government and motivate empathetic decisions. Our approach, combining low-level entities to create visualizations, provides value to an explorative and empathetic workflow. We show that the design space for visualizing this kind of data has a lot of potential and that it is possible to combine qualitative and quantitative approaches to data analysis.
Helping overcome distance, the use of videoconferencing tools has surged during the pandemic. To shed light on the consequences of videoconferencing at work, this study takes a granular look at the implications of the self-view feature for meeting outcomes. Building on self-awareness research and self-regulation theory, we argue that by heightening the state of self-awareness, self-view engagement depletes participants’ mental resources and thereby can undermine online meeting outcomes. Evaluation of our theoretical model on a sample of 179 employees reveals a nuanced picture. Self-view engagement while speaking and while listening is positively associated with self-awareness, which, in turn, is negatively associated with satisfaction with meeting process, perceived productivity, and meeting enjoyment. The criticality of the communication role is put forward: looking at self while listening to other attendees has a negative direct and indirect effect on meeting outcomes; however, looking at self while speaking produces equivocal effects.
Der nutzbringenden Einsatz einer Datenbrille besteht nicht nur aus der Brille selbst. Die potenzielle ressourcenschonende Assistenz bei der Abarbeitung von komplexen Workflows bedarf eine ausreichende Integration in die Anwendungssystemlandschaft. Implikation sind demnach zwei Hauptelemente: die Brille selbst und die Integrationssoftware. Beide Komponenten sind in geeigneter Form auszulegen und auf die intendierten Anwendungsfälle zu konfigurieren. Dieser Beitrag fasst die Erfahrungen aus zahlreichen Projekten zusammen und liefert einen Überblick über die Herausforderungen bei AR-Einführungen.
Bewertung ausgewählter Aspekte des neuen „Gesetzes zum Schutz von Geschäftsgeheimnissen“ (GeschGehG)
(2021)
Durch die steigende Bedeutung von grenzüberschreitendem Unternehmensverkehr, Globalisierung und Outsourcing sowie dem Einsatz von Telekommunikationsmitteln ist eine effektive und einheitliche Regelung zum Schutz von Geschäftsgeheimnissen unentbehrlich, da infolge einer Zunahme von Praktiken, wie Wirtschaftsspionage und Verletzungen von Geheimhaltungspflichten, welche eine rechtswidrige Aneignung von
Geschäftsgeheimnissen bezwecken, eine verstärkte Gefährdungslage für die Geheimhaltung von Geschäftsgeheimnissen besteht. Insbesondere deshalb soll dieser Beitrag die Frage beantworten, ob die Richtlinie (EU) 2016/943 (Geheimnisschutzrichtlinie) europarechtskonform in das Gesetz zum Schutz von Geschäftsgeheimnissen (GeschGehG) umgesetzt worden ist (zur Historie I.). Der Schwerpunkt liegt hierbei auf dem Schutzbereich (II.) und vornehmlich auf der Frage, wie das Merkmal des kommerziellen Wertes zu verstehen ist, ob jegliche Geheimnisse eines Unternehmens geschützt sind und inwiefern sich der Geheimnisschutz durch die geforderten angemessenen Geheimhaltungsmaßnahmen für Geheimnisinhaber verändert. Betrachtet wird ebenfalls, ob der deutsche Gesetzgeber befugt ist, ein berechtigtes Interesse an der Geheimhaltung zu fordern. Spätestens seit Snowdens Enthüllungen genießt die Aufdeckung von unethischen oder illegalen Verhaltensweisen
gesteigerte Aufmerksamkeit in der Bevölkerung und Rechtswissenschaft. Für den Hinweisgeberschutz ergeben sich durch das GeschGehG Neuerungen. Hinsichtlich des umfassenden Schutzbereiches des GeschGehG wird betrachtet, ob und wann eine unternehmensexterne Offenlegung von Geschäftsgeheimnissen zulässig ist (III.). Hierzu wird beantwortet, ob die bisherige Rechtsprechung zum sog. Eskalationsmodell
weiterhin angewandt werden muss und wie sich das Verhältnis zur allgemeinen arbeitsvertraglichen Verschwiegenheitspflicht aus § 241 Abs. 2 BGB, sowohl aus dem laufenden als auch dem beendeten Arbeitsverhältnis, darstellt. Eine abschließende Bewertung (IV.) vervollständigt den Beitrag.
