Increased media literacy in the population is one way to counter these issues and their implications. This especially applies to the sub-concept of journalism literacy, focusing on the ability to consume news critically and reflectively, thus enabling democratic participation. For media companies, promoting journalism literacy seems logical for economic and altruistic reasons. However, research on German initiatives is scarce. This article presents an explorative qualitative survey of experts from seven media companies offering journalistic media education projects in German schools, focusing on the initiatives' content, structure, and motivation. Results show that initiatives primarily aim at students and teachers, offering mostly education on journalism (e.g., teaching material) and via journalism (e.g., journalistic co-production with students). While these projects mainly provide information on the respective medium and journalistic practices, dealing with disinformation is also a central goal. Most initiatives are motivated both extrinsically (e.g., reaching new audiences) and intrinsically (e.g., democratic responsibility). Despite sometimes insufficient resources and reluctant teachers, media companies see many opportunities in their initiatives: Gaining trust and creating resilience against disinformation are just two examples within the larger goal of enabling young people to be informed and opinionated members of a democratic society.}, language = {en} } @article{CaspariSadeghi2022, author = {Caspari-Sadeghi, Sima}, title = {Learning assessment in the age of big data: Learning analytics in higher education}, series = {Cogent Education}, volume = {2023}, journal = {Cogent Education}, number = {Volume 110, issue 1}, publisher = {Taylor \& Francis}, doi = {0.1080/2331186X.2022.2162697}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-12236}, pages = {11 Seiten}, year = {2022}, abstract = {Data-driven decision-making and data-intensive research are becoming prevalent in many sectors of modern society, i.e. healthcare, politics, business, and entertainment.

Meanwhile, it is acknowledged that educa-tion lacks computational infrastructure and human capacity to fully exploit the potential of big data. This paper explores the use of Learning Analytics (LA) in higher education for measurement purposes. Four main LA functions in the assessment are outlined: (a) monitoring and analysis, (b) automated feedback, (c) prediction, prevention, and intervention, and (d) new forms of assessment.

These changes mostly affect the Controller to achieve GDPR-compliant privacy policies and management.However, measures to give users a better understanding of privacy, which is essential to generate legitimate interest in the Controller, are often skipped. We recommend addressing this issue by the usage of privacy preference languages, whereas users define rules regarding their preferences for privacy handling. In the literature, preference languages only work with their corresponding privacy language, which limits their applicability. In this paper, we propose the ConTra preference language, which we envision to support users during privacy policy negotiation while meeting current technical and legal requirements. Therefore, ConTra preferences are defined showing its expressiveness, extensibility, and applicability in resource-limited IoT scenarios. In addition, we introduce a generic approach which provides privacy language compatibility for unified preference matching.}, language = {en} } @article{Voigt2023, author = {Voigt, Brigitte}, title = {EU regulation of gene-edited plants — A reform proposal}, series = {Frontiers in Genome Editing}, volume = {5}, journal = {Frontiers in Genome Editing}, publisher = {Frontiers Media S.A.}, address = {Lausanne, Switzerland}, issn = {2673-3439}, doi = {10.3389/fgeed.2023.1119442}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-11849}, pages = {7 Seiten}, year = {2023}, abstract = {This article presents a proposal on how the European Union's regulatory framework on genetically modified (GM) plants should be reformed in light of recent developments in genomic plant breeding techniques.

Understanding the choice between the approaches is important for two reasons. First, the added value of each approach depends on how much is known about the phenomenon of interest at the time of the analysis. Second, because of the specializations of methods, there are benefits to a division of labor between researchers who have expertise in the application of a given method. In this preregistered study, we test two hypotheses that follow from these arguments. We theorize that exploratory research is chosen when little is known about a phenomenon and a confirmatory approach is taken when more knowledge is available. A complementary hypothesis is that quantitative researchers opt for confirmatory designs and qualitative researchers for exploration because of their academic socialization. We test the hypotheses with a survey experiment of more than 900 political scientists from the United States and Europe. The results indicate that the state of knowledge has a significant and sizeable effect on the choice of the approach. In contrast, the evidence about the effect of methods expertise is more ambivalent.}, language = {en} } @article{HauptFritsch, author = {Haupt, Harry and Fritsch, Markus}, title = {Quantile Trend Regression and Its Application to Central England Temperature}, series = {Mathematics}, volume = {10}, journal = {Mathematics}, number = {3}, editor = {Rykov, Vladimir V.}, publisher = {MDPI}, issn = {2227-7390}, doi = {10.3390/math10030413}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-10382}, abstract = {The identification and estimation of trends in hydroclimatic time series remains an important task in applied climate research. The statistical challenge arises from the inherent nonlinearity, complex dependence structure, heterogeneity and resulting non-standard distributions of the underlying time series. Quantile regressions are considered an important modeling technique for such analyses because of their rich interpretation and their broad insensitivity to extreme distributions. This paper provides an asymptotic justification of quantile trend regression in terms of unknown heterogeneity and dependence structure and the corresponding interpretation. An empirical application sheds light on the relevance of quantile regression modeling for analyzing monthly Central England temperature anomalies and illustrates their various heterogenous trends. Our results suggest the presence of heterogeneities across the considered seasonal cycle and an increase in the relative frequency of observing unusually high temperatures.}, language = {en} } @article{CaspariSadeghi, author = {Caspari-Sadeghi, Sima}, title = {Applying Learning Analytics in Online Environments: Measuring Learners' Engagement Unobtrusively}, series = {Frontiers in Education}, journal = {Frontiers in Education}, doi = {10.3389/feduc.2022.840947}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-10440}, pages = {1 -- 6}, abstract = {Prior to the emergence of Big Data and technologies such as Learning Analytics (LA), classroom research focused mainly on measuring learning outcomes of a small sample through tests.

In particular, the social reappraisal of the Holocaust is emblematic of this. However, when considering the genocide on the Herero and Nama in present-day Namibia, it is puzzling that an official recognition was only pronounced after almost 120 years, in May 2021. For a long time, silence surrounded this colonial cruelty in German political discourse. Although the discourse on German responsibility toward Namibia emerged after the end of World War II, it initially appeared detached from the genocide. That silence on colonial atrocities is to be considered a cruelty itself. Studies on silence have been expanding and becoming richer. Building on these works, the paper sets two goals: First, it advances the theorization of silence by producing a new typology, which is then integrated into discourse-bound identity theory. Second, it applies this theory to the analysis of the silencing and later acknowledging of the genocide on the Herero and Nama by German political elites. To this end, Bundestag debates, official documents, and statements by relevant political actors are analyzed in the period from 1980 to 2021. The results reveal the dynamics between hegemonic and counter-hegemonic discursive formations, how those are shifting in a period of 40 years, and what role silence plays in it. Beyond our emphasis on the genocide on the Herero and Nama, our findings might benefit future studies as the approach proposed in this paper can make silence a tangible research object for global studies.}, language = {en} } @article{MandarawiRottmeierRezaeighaleetal.2020, author = {Mandarawi, Waseem and Rottmeier, J{\"u}rgen and Rezaeighale, Milad and de Meer, Hermann}, title = {Policy-Based Composition and Embedding of Extended Virtual Networks and SFCs for IIoT}, series = {Algorithms}, volume = {13}, journal = {Algorithms}, number = {9}, publisher = {MDPI}, issn = {1999-4893}, doi = {10.3390/a13090240}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-8488}, year = {2020}, abstract = {The autonomic composition of Virtual Networks (VNs) and Service Function Chains (SFCs)based on application requirements is significant for complex environments. In this paper, we use graph transformation in order to compose an Extended Virtual Network (EVN) that is based on different requirements, such as locations, low latency, redundancy, and security functions. The EVN can represent physical environment devices and virtual application and network functions. We build a generic Virtual Network Embedding (VNE) framework for transforming an Application Request (AR) to an EVN. Subsequently, we define a set of transformations that reflect preliminary topological, performance, reliability, and security policies. These transformations update the entities and demands of the VN and add SFCs that include the required Virtual Network Functions (VNFs). Additionally, we propose a greedy proactive heuristic for path-independent embedding of the composed SFCs. This heuristic is appropriate for real complex environments, such as industrial networks. Furthermore, we present an Industrail Internet of Things (IIoT) use case that was inspired by Industry 4.0 concepts,in which EVNs for remote asset management are deployed over three levels; manufacturing halls and edge and cloud computing. We also implement the developed methods in Alevin and show exemplary mapping results from our use case. Finally, we evaluate the chain embedding heuristic while using a random topology that is typical for such a use case, and show that it can improve the admission ratio and resource utilization with minimal overhead.}, language = {en} } @article{Schiffbeck2020, author = {Schiffbeck, Adrian}, title = {The Spiritual "Freelancers": Young People, Religiosity and Community Problem Solving}, series = {SCIENTIA MORALITAS - International Journal of Multidisciplinary Research}, volume = {2020}, journal = {SCIENTIA MORALITAS - International Journal of Multidisciplinary Research}, number = {Volume 5, no. 1}, doi = {10.5281/zenodo.3959810}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-9268}, pages = {131 -- 152}, year = {2020}, abstract = {Earlier research showed that religion is related to participation among adolescents.

Data comes from several semistructured interviews with participants in a civic project conducted in the city of Timisoara (Romania). Findings indicated a low impact of the social religious component on engagement. The cognitive dimension of belief and the emotional bonding (prayer, ritual connection to the higher reality) function as indirect motivators, through the moral element of behavior. Results also showed a privatization of spiritual life at young adults (the invisible religion): estrangement from doctrines and the development of an individualistic type of morality, meant to drive volunteer activities further.}, language = {en} }
