Ein zentrales Instrument stellen dabei schulische Medienkonzepte dar, die gemeinsam vereinbarte Orientierungen für die schulische Arbeit und Schulentwicklungsprozesse enthalten. Zudem stellt die Medienkonzeptentwicklung einen Bestandteil theoretischer Modelle zur Erfassung und Beschreibung von Qualitätsdimensionen schulischer Medienbildung dar. Vor diesem Hintergrund untersucht der vorliegende Beitrag (1) die Relevanz von Medienkonzepten aus der Sicht von Schulleitungen und Schulträgern. Außerdem wird beleuchtet, (2) welche Personengruppen an den Schulen für Aufgaben im Kontext des Medienkonzeptes zuständig sind und (3) ob signifikante Unterschiede der schulischen Rahmenbedingungen, des Schulleitungshandelns und des Support je nach Vorhandensein eines Medienkonzeptes vorzufinden sind. Die Fragestellungen werden explorativ auf Grundlage der triangulativ angelegten Untersuchung des technischen und pädagogischen Supports an Schulen bearbeitet, in deren Rahmen N = 601 Lehrkräfte der Sekundarstufe I befragt wurden. Zudem wurden Interviews mit N = 8 Schulleitungen sowie N = 14 Schulträgern, die jeweils möglichst weit im Digitalisierungsprozess vorangeschritten sind, geführt und inhaltsanalytisch ausgewertet. Im Ergebnis zeigt sich, dass die Relevanz von Medienkonzepten für eine gelingende Schulentwicklung mit digitalen Medien als hoch eingeschätzt wird. Des Weiteren wird ersichtlich, dass die in den Einzelschulen für Belange der Medienkonzeptentwicklung zuständigen Akteursgruppen vielfältig zusammengesetzt sind. Ferner können bedeutsame Unterschiede im Hinblick auf die untersuchten Indikatoren je nach Vorhandensein eines Medienkonzeptes aufgezeigt werden. Die Arbeit mit Medienkonzepten kann somit das Herzstück der Schulentwicklung im Kontext der Digitalisierung darstellen.}}, author = {{Heldt, Melanie and Lorenz, Ramona and Eickelmann, Birgit}}, issn = {{0340-4099}}, journal = {{Unterrichtswissenschaft}}, number = {{3}}, pages = {{447--468}}, title = {{{Relevanz schulischer Medienkonzepte als Orientierung für die Schule im Zuge der fortschreitenden Digitalisierung}}}, doi = {{10.1007/s42010-020-00070-y}}, volume = {{48}}, year = {{2020}}, } @article{28843, author = {{Eickelmann, Birgit}}, journal = {{Lehren & Lernen.

Since dietary habits are acquired during early life, describing age and time trends of flavonoid intake and major food sources are important for monitoring and disease prevention in later life. We aimed to describe total flavonoid intake and food sources and to investigate age and time trends of flavonoid intake in 3–18-year-olds, from the Dortmund Nutritional and Anthropometric Longitudinally Designed study from 1985 to 2016. Intake was assessed annually using 3-d weighed food records (WFR). Flavonoid values were assigned using the United States Department of Agriculture database. Foods contributing to intake were determined. Age and time trends in total flavonoid and isoflavone density were analysed by sex with PROC MIXED. In total, 1312 children completed 10 758 WFR. Across all ages, daily mean total flavonoid density was lower in boys compared with girls (134 v. 146 mg/4184 kJ) and no difference in median isoflavone density (0·04 mg/4184 kJ per d) was found. The top five foods contributing to total flavonoid intake were apple with peel (15·0/17·1 %), strawberries (5·9/6·1 %), chocolate spread (3·9/3·5 %), orange juice (3·5/3·4 %) and pasta (3·5/3·4 %) for boys and girls, respectively. Overall, in boys, total flavonoid density decreased over the course of age and time. In girls, there was no association with age or time. In both sexes, isoflavone density followed a U-shaped age trend with no change over time. From a public health perspective, the overall observed downwards trend of flavonoid intake in boys deserves attention.

The main contributors of fibre to the diet are the cell walls of plant tissues, which are supramolecular polymer networks containing variable proportions of cellulose, hemicelluloses, pectic substances, and non-carbohydrate components, such as lignin. Other contributors of fibre are the intracellular storage oligosaccharides, such as fructans. A distinction needs to be made between intrinsic sources of dietary fibre and purified forms of fibre, given that the three-dimensional matrix of the plant cell wall confers benefits beyond fibre isolates. Movement through the digestive tract modifies the cell wall structure and may affect the interactions with the colonic microbes (e.g., small intestinally non-absorbed carbohydrates are broken down by bacteria to short-chain fatty acids, absorbed by colonocytes). These aspects, combined with the fibre associated components (e.g., micronutrients, polyphenols, phytosterols, and phytoestrogens), may contribute to the health outcomes seen with the consumption of dietary fibre. Therefore, where possible, processing should minimise the degradation of the plant cell wall structures to preserve some of its benefits.

There is increasing evidence, not only for patients with type 2 diabetes but also for healthy individuals, that higher body fatness or waist circumference (WC) has a negative impact on renal function to excrete acids (NAE). We hypothesized that adiposity-related inflammation molecules might mediate this relation between adiposity and renal acid excretion function. Twelve biomarkers of inflammation were measured in fasting blood samples from 162 adult participants (18–25 yr old) of the Dortmund Nutritional and Anthropometric Longitudinally Designed (DONALD) study who had undergone anthropometric measurements and collected 24-h urine samples. Both Baron and Kenny’s (B&K’s) steps to test mediation and causal mediation analysis were conducted to examine the potential mediatory roles of biomarkers of inflammation in the WC-24-h pH relationship after strictly controlling for laboratory-measured NAE. In B&K’s mediation analysis, leptin, soluble intercellular adhesion molecule 1 (sICAM-1), and adiponectin significantly associated with the outcome 24-h pH and attenuated the WC-pH relation. In agreement herewith, causal mediation analysis estimated the “natural indirect effects” of WC on 24-h pH via leptin ( P = 0.01) and adiponectin ( P = 0.03) to be significant, with a trend for sICAM-1 ( P = 0.09). The calculated proportions mediated by leptin, adiponectin, and sICAM-1 were 64%, 23%, and 12%, respectively. Both mediation analyses identified an inflammatory cytokine (leptin) and an anti-inflammatory cytokine (adiponectin) along with sICAM-1 as being potentially involved in mediating adiposity-related influences on renal acid excretion capacity. }}, author = {{Hua, Yifan and Herder, Christian and Kalhoff, Hermann and Buyken, Anette and Esche, Jonas and Krupp, Danika and Wudy, Stefan A. and Remer, Thomas}}, issn = {{1931-857X}}, journal = {{American Journal of Physiology-Renal Physiology}}, pages = {{F469--F475}}, title = {{{Inflammatory mediators in the adipo-renal axis: leptin, adiponectin, and soluble ICAM-1}}}, doi = {{10.1152/ajprenal.00257.2020}}, year = {{2020}}, } @article{27801, author = {{Nyasordzi, Juliana and Penczynski, Katharina and Remer, Thomas and Buyken, Anette}}, issn = {{1932-6203}}, journal = {{PLOS ONE}}, title = {{{Early life factors and their relevance to intima-media thickness of the common carotid artery in early adulthood}}}, doi = {{10.1371/journal.pone.0233227}}, year = {{2020}}, } @article{27803, author = {{Schwingshackl, Lukas and Neuenschwander, Manuela and Hoffmann, Georg and Buyken, Anette and Schlesinger, Sabrina}}, issn = {{0002-9165}}, journal = {{The American Journal of Clinical Nutrition}}, pages = {{917--918}}, title = {{{Reply to Khan et al.}}}, doi = {{10.1093/ajcn/nqaa006}}, year = {{2020}}, } @article{27806, abstract = {{AbstractTrend analyses based on dietary records suggest decreases in the intakes of total sugar (TS), added and free sugar since 2005 among children and adolescents in Germany.

Furthermore, adolescents are more susceptible to underreporting than children. We thus analysed time and age trends in urinary fructose excretion (FE), sucrose excretion (SE) and the sum of both (FE + SE) as biomarkers for sugar intake among 8·5–16·5-year-old adolescents. Urinary sugar excretion was measured by UPLC-MS/MS in 997 24-h urine samples collected from 239 boys and 253 girls participating in the Dortmund Nutritional and Anthropometric Longitudinally Designed (DONALD) study cohort between 1990 and 2016. Time and age trends of log-transformed FE, SE and FE + SE were analysed using polynomial mixed-effects regression models. Between 1990 and 2016, FE as well as FE + SE decreased (linear time trend: P = 0·0272 and P < 0·0001, respectively). A minor increase in excretion during adolescence was confined to FE (linear age trend: P = 0·0017). The present 24-h excretion measurements support a previously reported dietary record-based decline in sugar intake since 2005.

In this context, the International Computer and Information Literacy Study (IEA-ICILS 2018) has identified substantial social disparities concerning computer and information literacy of grade 8 students. Furthermore, it has been observed that many schools, especially those located in socioeconomically challenged areas, are particularly engaged in supporting students’ digital literacy and innovatively designing learning processes with information and communications technology (ICT). Empirical studies have made it apparent that some schools have high average achievements concerning domains such as reading literacy and mathematics in spite of socioeconomically challenged student bodies. These schools are regarded as being organizationally resilient. This contribution focusses on these organizationally resilient schools with regard to the domain of computer and information literacy. It aims to investigate how these schools can be classified as a typology according to selected school and/or teacher characteristics. Methods As a first step, representative samples of IEA-ICILS 2018 are used to identify organizationally resilient schools by using students’ achievement measures (plausible values) and their background information regarding their families’ socio-economic status. In order to develop a typology, latent profile analyses (LPA) are conducted by using input and process indicators on the school level, which have been proven to be relevant for implementation through existing empirical research. Results About one twentieth of the schools examined in this contribution can be regarded as organizationally resilient and can be allocated onto a typology of three school types that are characterized by different school-level factors. Conclusions The international comparison permits the conclusion that the phenomenon of organizational resilience is also existent with regard to the content domain of computer and information literacy. However, the proportion of resilient schools is subject to considerable variation between countries. }}, author = {{Drossel, Kerstin and Eickelmann, Birgit and Vennemann, Mario}}, issn = {{2196-0739}}, journal = {{Large-scale Assessments in Education}}, pages = {{1--19}}, title = {{{Schools overcoming the digital divide: in depth analyses towards organizational resilience in the computer and information literacy domain}}}, doi = {{10.1186/s40536-020-00087-w}}, volume = {{8}}, year = {{2020}}, } @inbook{27840, author = {{Vennemann, Mario and Drossel, Kerstin and Eickelmann, Birgit}}, booktitle = {{ICILS 2018 #NRW.

(2019). Preparing for life in a digital world: IEA International Computer and Information Literacy Study 2018 International Report. Amsterdam: International Association for the Evaluation of Educational Achievement (IEA). Retrieved from https://www.iea.nl/sites/default/files/2019-11/ICILS%202019%20Digital%20final%2004112019.pdf). Educational systems play a key role in the mediation of these skills (Eickelmann. Second Handbook of Information Technology in Primary and Secondary Education. Cham: Springer, 2018). However, previous studies have shown differences in students’ computer and information literacy (CIL). Although various approaches have been used to explain these differences, process data, such as response times, have never been taken into consideration. Based on data from the IEA-study ICILS 2013 of the Czech Republic, Denmark and Germany, this secondary analysis examines to what extent response times can be used as an explanatory approach for differences in CIL also within different groups of students according to student background characteristics (gender, socioeconomic background and immigrant background). Methods First, two processing profiles using a latent profile analysis (Oberski, D. (2016). Mixture Models: Latent Profile and Latent Class Analysis. In J. Robertson & M. Kaptein (Eds.), Modern Statistical Methods for HCI (pp. 275–287). Switzerland: Springer. 10.1007/978-3-319-26633-6) based on response times are determined—a fast and a slow processing profile. To detect how these profiles are related to students’ CIL, also in conjunction with students’ background characteristics (socioeconomic and immigrant background), descriptive statistics are used. Results The results show that in the Czech Republic and Germany, students belonging to the fast processing profile have on average significantly higher CIL than students allocated to the slow processing profile. In Denmark, there are no significant differences. Concerning the student background characteristics in the Czech Republic, there are significant negative time-on-task effects for all groups except for students with an immigrant background and students with a high parental occupational status. There are no significant differences in Denmark. For Germany, a significant negative time-on-task effect can be found among girls. However, the other examined indicators for Germany are ambiguous. Conclusions The results show that process data can be used to explain differences in students’ CIL: In the Czech Republic and Germany, there is a correlation between response times and CIL (significant negative time-on-task effect). Further analysis should also consider other aspects of CIL (e.g. reading literacy). What becomes clear, however, is that when interpreting and explaining differences in competence, data should also be included that relates to the completion process during testing. }}, author = {{Heldt, Melanie and Massek, Corinna and Drossel, Kerstin and Eickelmann, Birgit}}, issn = {{2196-0739}}, journal = {{Large-scale Assessments in Education}}, pages = {{1--20}}, title = {{{The relationship between differences in students’ computer and information literacy and response times: an analysis of IEA-ICILS data}}}, doi = {{10.1186/s40536-020-00090-1}}, volume = {{8}}, year = {{2020}}, } @article{27865, author = {{Eickelmann, Birgit and Drossel, Kerstin}}, journal = {{SchulVerwaltung Baden-Württemberg}}, number = {{12}}, pages = {{328--331}}, title = {{{Schulschließungen und Perspektiven für die Pandemie-Zeit}}}, volume = {{29}}, year = {{2020}}, } @inbook{27866, author = {{Drossel, Kerstin and Eickelmann, Birgit}}, booktitle = {{Mobile Medien im Schulkontext (Reihe Medienbildung und Gesellschaft)}}, editor = {{Meister, Dorothee M. and Midt, Ilka}}, pages = {{135--153}}, publisher = {{Springer}}, title = {{{Der Einsatz von Tablets am Gymnasium und der Zusammenhang mit der Entwicklung computerbezogener Kompetenzen von Schüler*innen}}}, year = {{2020}}, } @inbook{27867, author = {{Eickelmann, Birgit and Drossel, Kerstin}}, booktitle = {{Encyclopedia of Education and Information Technologies}}, editor = {{Tatnall, Arthur}}, isbn = {{9783030105754}}, pages = {{1577--1589}}, publisher = {{Springer}}, title = {{{Students’ computer literacy and the use of tablets in upper secondary schools}}}, doi = {{10.1007/978-3-030-10576-1}}, year = {{2020}}, } @book{27869, author = {{Eickelmann, Birgit and Drossel, Kerstin}}, publisher = {{Vodafone Stiftung}}, title = {{{Digitales Potenzial.

Hence, hybrid structures made of aluminum and steel materials are increasingly being used in automotive applications. Due to limitations in the quality of resistance spot welding, self-piercing riveting can be used as an alternative process to join sheets from different material groups. The aim of this project is to develop a computational method to assess the self-piercing riveted components subjected to the cyclic loads. To achieve this goal, two approaches are followed: Evaluation unsing internal forces: A substitute model is developed to describe the stiffness of self-piercing riveted joints subjected to different loading conditions. The parameters of the substitute model are identified and the internal force components acting on the joint are evaluated. The model provides the basis for the subsequent fatigue life estimation of self-piercing riveted components. For joints subjected to low bending moments, the fatigue life of components can be estimated accurately. Due to lack of specimen geometries producing pure bending and the combination of tension-bending forces, it is not possible to estimate the fatigue life of complex components subjected to high bending moments. Based on the results of [Mesc 16], the methodology is further developed to determine the stresses acting on the joint and to characterize the joining point with the use of simulations. The local concept proposed in the FKM guideline nonlinear provides the basis for the analytical assessment of self-piercing riveted components. In this regard, the cyclic behavior of the material and the local stresses are required as input data. The cyclic behavior of the aluminum EN AW-6181A-T6 and steel HX340LAD sheets were already determined in the previous project. Subsequently, in this project the properties of the rivet made of 38B2 steel are identified. The finite element analysis using elastic-plastic material behavior is used to determine the stresses in the joint subjected to the cyclic loads. To verify the model, the results of simulations and experiments are compared concerning the crack initiation zone as well as the determined number of cycles. To determine the stresses that can be used for the analytical assessment, the damage relevant load components need to be identified. In this regard, it is recommended to use the normal stress perpendicular to the crack propagation direction, the stress of crack opening mode I. Using the damage parameter PRAM and considering the support factors according to the FKM guideline nonlinear, a reliable estimation of the crack initiation zone within the joint is possible. Regarding the joint made of aluminum sheet EN AW-6181A, the methodology is able to provide promising results. However, regarding the joints made of aluminum EN AW-6181A and steel HX340LAD sheets, there is still potential to improve the results. The reasons for this are described in chapter 7.2.5 and 7.2.6. An analytical fatigue assessment is relatively easy to achieve with procedure 1. However, contrary to the objective formulated above, expensive fatigue tests are necessary to determine the failure conditions (strength values). This disadvantage can be circumvented by determining the strength information of individual joining points under different load types using procedure 2. The latter, in return, is not suitable for the assessment of complex components with several joining points. Due to the increasing calculation times of the simulation, the application in this case is not economically reasonable. By the described combination of method 1 and 2, the disadvantages of the two individual concepts can be compensated. An analytical fatigue assessment of self-piercing riveted components can be carried out based on the cyclic material behavior. The objective of the project was achieved.}}, author = {{Otroshi, Mortaza and Meschut, Gerson and Masendorf, Lukas and Esderts, Alfons}}, isbn = {{978-3-86776-602-9}}, pages = {{282}}, publisher = {{Europäische Forschungsgesellschaft für Blechverarbeitung e.V.

Our results show that the metal atoms present in the structure of C2N are the reactive sites, which catalyze the aforesaid reaction by strong adsorption and activation of N2. We further demonstrate that a lower onset electrode potential is required for Fe--C2N than for Au--C2N. Thus, Fe--C2N is theoretically predicted to be a potentially better NRR catalyst at ambient conditions than Au--C2N owing to the larger adsorption energy of N2 molecules. Furthermore, we have experimentally shown that single sites of Au and Fe supported on nitrogen-doped porous carbon are indeed active NRR catalysts. However, in contrast to our theoretical results, the Au-based catalyst performed slightly better with a Faradaic efficiency (FE) of 10.1{\%} than the Fe-based catalyst with an FE of 8.4{\%} at −0.2 V vs. RHE. The DFT calculations suggest that this difference is due to the competitive hydrogen evolution reaction and higher desorption energy of ammonia.}}, author = {{Sahoo, Sudhir K. and Heske, Julian Joachim and Antonietti, Markus and Qin, Qing and Oschatz, Martin and Kühne, Thomas}}, journal = {{ACS Applied Energy Materials}}, number = {{10}}, pages = {{10061--10069}}, publisher = {{American Chemical Society}}, title = {{{Electrochemical N2 Reduction to Ammonia Using Single Au/Fe Atoms Supported on Nitrogen-Doped Porous Carbon}}}, doi = {{10.1021/acsaem.0c01740}}, volume = {{3}}, year = {{2020}}, } @article{21241, abstract = {{In this work, a high-throughput screening of binary and ternary pnictide- and halide-based compounds is performed to identify promising p-type transparent conductors.

It has a lasting influence on the perception of cultural identity as well as on the interactions between research, the cultural economy and society. Throughout the last three decades, many cultural heritage institutions have contributed a wealth of digital representations of cultural assets (2D digital reproductions of paintings, sheet music, 3D digital models of sculptures, monuments, rooms, buildings), audio-visual data (music, film, stage performances), and procedural research data such as encoding and annotation formats. The long-term preservation and FAIR availability of research data from the cultural heritage domain is fundamentally important, not only for future academic success in the humanities but also for the cultural identity of individuals and society as a whole. Up to now, no coordinated effort for professional research data management on a national level exists in Germany. NFDI4Culture aims to fill this gap and create a user-centered, research-driven infrastructure that will cover a broad range of research domains from musicology, art history and architecture to performance, theatre, film, and media studies. The research landscape addressed by the consortium is characterized by strong institutional differentiation. Research units in the consortium's community of interest comprise university institutes, art colleges, academies, galleries, libraries, archives and museums. This diverse landscape is also characterized by an abundance of research objects, methodologies and a great potential for data-driven research. In a unique effort carried out by the applicant and co-applicants of this proposal and ten academic societies, this community is interconnected for the first time through a federated approach that is ideally suited to the needs of the participating researchers. To promote collaboration within the NFDI, to share knowledge and technology and to provide extensive support for its users have been the guiding principles of the consortium from the beginning and will be at the heart of all workflows and decision-making processes. Thanks to these principles, NFDI4Culture has gathered strong support ranging from individual researchers to high-level cultural heritage organizations such as the UNESCO, the International Council of Museums, the Open Knowledge Foundation and Wikimedia. On this basis, NFDI4Culture will take innovative measures that promote a cultural change towards a more reflective and sustainable handling of research data and at the same time boost qualification and professionalization in data-driven research in the domain of cultural heritage. This will create a long-lasting impact on science, cultural economy and society as a whole.}}, author = {{Altenhöner, Reinhard and Blümel, Ina and Boehm, Franziska and Bove, Jens and Bicher, Katrin and Bracht, Christian and Brand, Ortrun and Dieckmann, Lisa and Effinger, Maria and Hagener, Malte and Hammes, Andrea and Heller, Lambert and Kailus, Angela and Kohle, Hubertus and Ludwig, Jens and Münzmay, Andreas and Pittroff, Sarah and Razum, Matthias and Röwenstrunk, Daniel and Sack, Harald and Simon, Holger and Schmidt, Dörte and Schrade, Torsten and Walzel, Annika-Valeska and Wiermann, Barbara}}, issn = {{2367-7163}}, journal = {{Research Ideas and Outcomes}}, title = {{{NFDI4Culture - Consortium for research data on material and immaterial cultural heritage}}}, doi = {{10.3897/rio.6.e57036}}, year = {{2020}}, }
