    Adoption, Use and Diffusion of Crisis Apps in Germany: A Representative Survey
    (Mensch und Computer 2019 - Tagungsband, 2019) Grinko, Margarita; Kaufhold, Marc-André; Reuter, Christian
    The research field of crisis informatics examines the potentials and limitations of information and communication technology in crises, disasters, and emergencies. Although ICT plays an increasingly large role in crisis response and management, in-depth studies on crisis apps and similar technology in the context of an emergency have been missing. Based on responses by 1024 participants in Germany, we examine the diffusion, usage, perception and adoption of mobile crisis apps as well as required functions and improvements. We conclude that crisis apps are still a little-known form of disaster ICT, but have potential for enhancing communication, keeping users up to date and providing a more effective crisis management as supplement to other media channels dependent on different underlying infrastructures. However, they should be adaptable to user characteristics, consider privacy, allow communication and offer valuable information to raise awareness of potential disasters without creating an overload. Also, the familiarity with and trust in crisis apps should be addressed to maximize their beneficial impact on crisis communication and management. We discuss further implications as well as directions for future research with larger target groups and specific usage scenarios.

    Detecting a Crisis: Comparison of Self-Reported vs. Automated Internet Outage Measuring Methods
    (Mensch und Computer 2022 - Workshopband, 2022) Orlov, Denis; Möller, Simon; Düfer, Sven; Haesler, Steffen; Reuter, Christian
    Every day, there are internet disruptions or outages around the world that affect our daily lives. In this paper, we analyzed these events in Germany in recent years and found out how they can be detected, and what impact they have on citizens, especially in crisis situations. For this purpose, we take a look at two different approaches to recording internet outages, namely the self-reporting of citizens and automatic reporting by algorithmic examination of the availability of IP networks. We evaluate the data of six major events with regard to their meaningfulness in quality and quantity. We found that due to the amount of data and the inherent imprecision of the methods used, it is difficult to detect outages through algorithmic examination. But once an event is publicly known by self-reporting, they have advantages to capture the temporal and spatial dimensions of the outage due to its nature of objective measurements. As a result, we propose that users’ crowdsourcing can enhance the detection of outages and should be seen as an important starting point to even begin an analysis with algorithm-based techniques, but it is to ISPs and regulatory authorities to support that.

    Marketing strategies of the German farm management information systems startups that reached critical mass
    (39. GIL-Jahrestagung, Digitalisierung für landwirtschaftliche Betriebe in kleinstrukturierten Regionen - ein Widerspruch in sich?, 2019) Iversen, Anna
    What kind of marketing strategies can lead to achievement of the critical mass on the agricultural market in Germany? To answer this question, all currently existing farm management startups in Germany were selected and the ones with critical mass were identified. Their marketing strategies were qualitatively analyzed and triangulated with the marketing strategies of online marketplaces.

    Monitoring of Digitization and Sustainability on Twitter
    (INFORMATIK 2023 - Designing Futures: Zukünfte gestalten, 2023) Vahdatnia, Ali; Peachkah, Danoosh
    In today's era of technological advancements, particularly in the realm of cyber technologies like the internet and social media platforms, conducting research on the reception of Digitization and Sustainability has become more accessible, affordable, and convenient. Among these platforms, Twitter stands out as a pioneering and appealing medium for such research endeavors. Therefore, we selected Twitter social media platform to analyze public opinions expressed through tweets and how these concepts are connected to skills and tools and the labor market. By gathering data related to specific keywords and utilizing SpaCy for sentiment analysis in our customized pipeline, we observed that a majority of tweets originating from Germany exhibited a positive sentiment towards sustainability strategies but expressed more negative views, especially regarding methods of leftover disposal. Additionally, we concluded that even a proficient analyzer may generate irrelevant results if the keywords being searched inherently possess negative sentiments.

    We discuss the potential for digitizing wine certification in Germany.

    Use of Information and Communication Technology in Healthcare Context by Older Adults in Germany: Initial Results of the Tech4Age Long-Term Study
    (i-com: Vol. 16, No. 2, 2017) Mertens, Alexander; Rasche, Peter; Theis, Sabine; Bröhl, Christina; Wille, Matthias
    In 2016 the interdisciplinary research team Tech4Age started its long-term survey to evaluate the use of information and communication technology (ICT) by older adults () in Germany. This study focuses on the use of ICT devices and applications, the evaluation how these devices are operated in terms of ergonomic hand positions, the investigation of health information usage as well as technology affinity, health literacy and computer literacy. The first run of the Tech4Age long-term study was done by sending a paper-based questionnaire to 5,000 individuals older than 60 years randomly selected from the total German population and equally locally distributed within Germany. Responses were collected from N = 551 participants with a mean age of 69.17 years (SD = 5.787). The gender ratio of the sample is balanced, including 51.3% male and 48.7% female. Results provide descriptive insights into technology usage and knowledge about influencing factors. Older adults already use modern ICT on a large scale, for example to do online banking or for mobility reasons (navigation, booking tickets, etc.), but health-related ICT products and applications have been used less, mainly due to mistrust. Investigation of health information usage showed that doctors and pharmacists are the main sources older adults rely on. Two thirds of all participants were satisfied with general information they got about health. The evaluation of the ergonomic use of ICT devices revealed a common way of use, namely that a majority of older adults prefer to use their ICT devices in the case of a small display in portrait mode and in the case of larger displays in portrait as well as landscape mode. Touch input is always performed with a finger or the second hand, the one not holding the device. The article will present and discuss the results in detail.

    Web scraping of food retail prices
    (42. GIL-Jahrestagung, Künstliche Intelligenz in der Agrar- und Ernährungswirtschaft, 2022) Loy, Jens-Peter; Ren, Yanjun
    In this paper, we develop a theory of food retail promotional strategy. We test the theory using online food retail prices. A python code is applied to retrieve information from the web page mytime.de. Mytime.de is an online grocery outlet that belongs to the Bünting Group, a food retailer in North-West Germany. The promotional sales on mytime.de show a complementary relationship between breadth and depth of sales, indicating that in order to attract consumers, stores raise both the number (breadth) and the depth of price promotions.
