Gleichzeitig eine hinterlegungsrechtliche Betrachtung der Entscheidungen „Orange-Book-Standard“ des BGH und „Huawei/ZTE“ des EuGH

Bei dieser rechtswissenschaftlichen Arbeit handelt es sich um eine Doktorarbeit, die im Jahr 2022 von der Freien Universität Berlin angenommen wurde. Sie beschäftigt sich mit dem Rechtsinstitut der Hinterlegung und dabei insbesondere mit der Grenzziehung zwischen der Hinterlegung als Erfüllungssurrogat und der Hinterlegung als Sicherheitsleistung. Aufbauend auf dieser Differenzierung wird untersucht, inwiefern die Hinterlegung im rechtlichen Bereich des Kontrahierungszwangs bereits angewendet wird und - mit Blick auf die Zukunft - angewendet werden könnte. Im Zentrum stehen dabei die Entscheidungen „Orange-Book-Standard“ des Bundesgerichtshofs aus 2011 und „Huawei/ZTE“ des Europäischen Gerichtshofs aus 2015

Shotgun Metagenomics of Deep Forest Soil Layers Show Evidence of Altered Microbial Genetic Potential for Biogeochemical Cycling

Soil microorganisms such as Bacteria and Archaea play important roles in the biogeochemical cycling of soil nutrients, because they act as decomposers or are mutualistic or antagonistic symbionts, thereby influencing plant growth and health. In the present study, we investigated the vertical distribution of soil metagenomes to a depth of 1.5 m in Swiss forests of European beech and oak species on calcareous bedrock. We explored the functional genetic potential of soil microorganisms with the aim to disentangle the effects of tree genus and soil depth on the genetic repertoire, and to gain insight into the microbial C and N cycling. The relative abundance of reads assigned to taxa at the domain level indicated a 5–10 times greater abundance of Archaea in the deep soil, while Bacteria showed no change with soil depth. In the deep soil there was an overrepresentation of genes for carbohydrate-active enzymes, which are involved in the catalyzation of the transfer of oligosaccharides, as well as in the binding of carbohydrates such as chitin or cellulose. In addition, N-cycling genes (NCyc) involved in the degradation and synthesis of N compounds, in nitrification and denitrification, and in nitrate reduction were overrepresented in the deep soil. Consequently, our results indicate that N-transformation in the deep soil is affected by soil depth and that N is used not only for assimilation but also for energy conservation, thus indicating conditions of low oxygen in the deep soil. Using shotgun metagenomics, our study provides initial findings on soil microorganisms and their functional genetic potential, and how this may change depending on soil properties, which shift with increasing soil depth. Thus, our data provide novel, deeper insight into the “dark matter” of the soil

COVID-19 pandemic and student reading achievement: findings from a school panel study

Since 2020, the COVID-19 pandemic had an impact on education worldwide. There is increased discussion of possible negative effects on students’ learning outcomes and the need for targeted support. We examined fourth graders’ reading achievement based on a school panel study, representative on the student level, with N = 111 elementary schools in Germany (total: N = 4,290 students, age: 9–10 years). The students were tested with the Progress in International Reading Literacy Study instruments in 2016 and 2021. The analysis focused on (1) total average differences in reading achievement between 2016 and 2021, (2) average differences controlling for student composition, and (3) changes in achievement gaps between student subgroups (i.e., immigration background, socio-cultural capital, and gender). The methodological approach met international standards for the analysis of large-scale assessments (i.e., multiple multi-level imputation, plausible values, and clustered mixed-effect regression). The results showed a substantial decline in mean reading achievement. The decline corresponds to one-third of a year of learning, even after controlling for changes in student composition. We found no statistically significant changes of achievement gaps between student subgroups, despite numerical tendencies toward a widening of achievement gaps between students with and without immigration background. It is likely that this sharp achievement decline was related to the COVID-19 pandemic. The findings are discussed in terms of further research needs, practical implications for educating current student cohorts, and educational policy decisions regarding actions in crises such as the COVID-19 pandemic

Pressing issues for oral care quality improvement: findings from the EU DELIVER project

Background: While oral health often takes a backseat to other health domains, it silently affects nearly half of the Worldwide population. The DELIVER project, funded by the EU’s Horizon Europe program, seeks to develop a blueprint model for improving the quality of oral health care for everyone. Methods: Applying the Nominal Group Technique (NGT), 17 stakeholders from various backgrounds participated in identifying pressing issues for oral care quality improvement across practice, community, and policy levels. Results: The results revealed significant differences at the different levels, with accessibility emerging as a prominent issue, encompassing affordability, availability, and acceptability of oral healthcare services. Conclusions: These findings emphasizes the need for policy reforms, increased investments, and a shift towards preventive and patient-centered dental care practices. It highlights the importance of collaborative efforts with multi-stakeholders and prioritizing pressing issues on a multi-level to drive positive change in improving oral care quality. © The Author(s) 2024.The authors disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This project has received funding from the European Union’s Horizon Europe research and innovation program under grant agreement 101057077: https://cordis.europa.eu/project/id/101057077

Genetic separation of Listeria monocytogenes causing central nervous system infections in animals

Listeria monocytogenes is a foodborne pathogen that causes abortion, septicemia, gastroenteritis and central nervous system (CNS) infections in ruminants and humans. L. monocytogenes strains mainly belong to two distinct phylogenetic groups, named lineages I and II. In general, clinical cases in humans and animals, in particular CNS infections, are caused by lineage I strains, while most of the environmental and food strains belong to lineage II. Little is known about why lineage I is more virulent than lineage II, even though various molecular factors and mechanisms associated with pathogenesis are known. In this study, we have used a variety of whole genome sequence analyses and comparative genomic tools in order to find characteristics that distinguish lineage I from lineage II strains and CNS infection strains from non-CNS strains. We analyzed 225 strains and identified single nucleotide variants between lineages I and II, as well as differences in the gene content. Using a novel approach based on Reads Per Kilobase per Million Mapped (RPKM), we identified 167 genes predominantly absent in lineage II but present in lineage I. These genes are mostly encoding for membrane-associated proteins. Additionally, we found 77 genes that are largely absent in the non-CNS associated strains, while 39 genes are especially lacking in our defined “non-clinical” group. Based on the RPKM analysis and the metadata linked to the L. monocytogenes strains, we identified 6 genes potentially associated with CNS cases, which include a transcriptional regulator, an ABC transporter and a non-coding RNA. Although there is not a clear separation between pathogenic and non-pathogenic strains based on phylogenetic lineages, the presence of the genes identified in our study reveals potential pathogenesis traits in ruminant L. monocytogenes strains. Ultimately, the differences that we have found in our study will help steer future studies in understanding the virulence mechanisms of the most pathogenic L. monocytogenes strains
