Ziel der Broschüre ist es, über die Möglichkeiten einer nachhaltigen Nutzung von Stroh in Deutschland zu informieren und ein Stimmungsbild von verschiedenen Akteuren zu einer zukünftigen Nutzung zu präsentieren. Dafür wurden über 50 Personen aus Landwirtschaft, Industrie, Politik und Wissenschaft befragt. Die Ergebnisse können eine bessere Erschließung der Ressource unterstützen.

Peer2Peer communication can take place in the traditional way via e-mail, forums or social media. One also finds dedicated apps for communication or organized in groups, such as WhatsApp, Telegram or Discord, the latter being particularly popular with digital gamers. Online games are another medium which can foster communication between people over a data connection, as direct messages can be sent through the provisions of the digital game worlds. Depending on the game provider and its headquarters, the terms and conditions differ in how the data is transmitted and processed. Access to private communications is important for governments and especially for the police work, for both to prevent and follow up on cybercrime and terrorist acts. On the other hand, the private and civil rights movements push for such interventions to occur only in the case of absolutely justified suspicion, with otherwise restricted access to transmitted conversations and data of private individuals and companies. Therefore, it is important that such access to messages is confirmed in advance by a law court. But even with approval, it is still difficult for the authorities to gain access from a technical perspective. While IP addresses and open communication can be intercepted quite easily, it is more difficult when secure messenger apps are used and only possible if there is direct access to the user's device or the app operator provides the authorities access via a master key. In digital games, access is even more complicated. In this work-in-progress paper the authors want to address a currently overlooked aspect of Peer2Peer communication; which is the provision of text messages via (testnet) blockchain systems, with special regard to the possibility of attaching encrypted messages to the transaction of blockchain tokens. It is to be noted that on the testnet versions of the blockchain systems no "KYC" takes place. While on the mainnet versions of the blockchain systems the purchase of tokens to send them later can only be done anonymously "over the counter", the testnet of most blockchain systems is completely free available. Everyone can create a blockchain Wallet, request testnet tokens and start sending encrypted messages anonymously. This work-in-progress paper aims to highlight and explain the authors' planned research in this field. ; peer-reviewed

The term nudge or nudging originally derives from the field of behavioural economics and describes a soft type of influence with the goal to elicit a certain behaviour. Thaler & Sunstein (1975) define nudging as a positive intervention that stimulates a voluntary change in behaviour without including external (negative) consequences. The idea of nudging has been booming in the USA for several years, while in Europe the concept of nudging remains largely unexplored. The focus is generally on the creation of politically motivated interventions and is particularly anchored in the field of health prevention (Quigley, 2013). Nudging in itself is based on motivational psychology models and shows parallels to the principle of gamification. Nudges can further be seen in a similar way to gamification, or as a relevant part of gamification, in the form of the game mechanics of achievements (Pfeiffer, 2018). However, in contrast to gamification, stimulus-response chains in the sense of incentives and penalties fade into the background and subtle strategies and positive interventions for decision optimization come to the fore. Nudging strategies have the potential to make behavioural alternatives appear more visible. For instance, in the area of physical activity, nudging can lead to the stairs becoming more attractive when compared to a lift (Hollands et al., 2013). Nudges also play a major role in (digital) game design, by for example guiding the player in the right direction or gently explaining why the player cannot choose a certain item. Furthermore, nudging can be a very effective element in the user experience design of apps by amongst others, making the user feel comfortable and ensuring that the app is used as intended (Pfeiffer, 2018). This paper aims to evaluate successful nudges from the world of games and apps and it is intended to inspire designers of virtual and blended learning systems to enhance the overall experience. ; peer-reviewed

Facebook has proposed to integrate the cryptocurrency 'Libra' into its services, a plan which has been heavily discussed in science, business and politics. On Steemit.com one receives a tradable-token namend Steem in return for writing popular articles or post comments while at Wildspark.me one is rewarded for discovering the next big YouTube video. This shows that Blockchain technologies have an undeniable influence on the development of today's Social Media Networks. On the one hand, we have the technology hype around Blockchain and what kind of new applications are made possible, and on the other hand, the speculation hype around digital tokens (cryptocurrencies) and new forms of investment (ICO, STO), which have in turn resulted in a large number of start-ups in the Social Media and Blockchain sector. Start-ups and products, which quite often disappear from the market in a relatively short time. This paper provides a Snapshot, how Blockchain technologies could influence established Social Networks and gives an overview of known start-ups and their platforms which facilitate Blockchain technologies (like Steemit, Social X, Obsidian, Indorse, Sola, HyperSpace, Ardor.rocks a.s.o.). Finally, a discussion on how Blockchain technologies can be used beyond speculation is provided. ; peer-reviewed

Digital/electronic identities are essential components of collaborative robots/robots and human-robot/robothuman interactions. Through such identities, digital agents (AI powered software or robots/bots) are entrusted with tasks in the name of certain individuals/companies. Digital identities can come from various sources; these can be assigned by an employer, through a service provided by a government entity or an external company specializing in the creation of such signatures or generated through an interface like Facebook Connect. All these different sources offer a range of varying levels of trust, both within the institution where the signature is principally used, but especially when interacting with third parties. Ultimately, this level of trust or its valuation is a determining factor in how far the authorization of the respective digital/electronic signature goes. The authors describe the application of digital/electronic signatures from human employees or legal entities which, simultaneously with the main task, generate sub-signatures for the respective digital agent.The topic is presented from a technical perspective as well as from a social science point of view. ; peer-reviewed
