Focusing on the most important private firms operating in U.S. industries, we investigate whether private peer disclosure—despite differing substantially from public firm disclosure—is incorporated into analysts’ forecasts. In a cross-sectional analysis, we document lower forecast quality in industries where private peers’ disclosure intensity is low. In contrast, when private peers’ disclosure intensity is high, forecast quality does not differ from that in industries with only public peers. We find consistent results for a subsample of U.S. private peers. Consistent with this interpretation, a difference-in-differences analysis documents increased analyst forecast activity around the disclosure dates of private peers. Together, these findings indicate that analysts incorporate private peers’ information when these peers are both economically important and sufficiently transparent, and highlight that variation in private firms’ disclosure intensity generates heterogenous externalities for public firms. Overall, our evidence supports a cost-benefit trade-off in analysts’ information acquisition, and, by documenting the relevance of private peers’ information for public firms, contributes to the debate on the externalities of private firms’ disclosure transparency.}}, author = {{Beyer, Bianca and Flagmeier, Vanessa and Kosi, Urska}}, issn = {{1556-5068}}, publisher = {{TRR 266 Accounting for Transparency}}, title = {{{Private Peers’ Disclosure Transparency and Public Firms’ Information Environment}}}, doi = {{10.2139/ssrn.4438123}}, year = {{2026}}, } @article{66075, abstract = {{Indefinite causal order (ICO) has the potential to be a new resource for quantum information processing.

These entangled states can have the form of one- or two-photon NOON states. We show that ICO can interchange one photon between both cavities without changing the state of the atom, something that is impossible to achieve for two cavities in well-defined order.

These needs are—according to Ainscow’s (2007) inclusive turn—not primarily ‘special educational needs’, but diverse needs of all learners. For the rather segregated German educational system, this endeavour applies especially to primary education, where needs are still developing and pupils are not yet assigned to different types of schooling according to their needs and abilities. Despite a substantial amount of research on pupils’ basic psychological needs for autonomy, competence and social relatedness (Ryan et al., 2022), strategies that technology education teachers apply in this regard are not yet well understood. Besides interventional studies on technology education, indicating effectiveness of self‑directed and action‑oriented teaching and learning, there is a dearth of research on how teachers address different needs as a routine. The purpose of the presented study is therefore to investigate and systematize actions and strategies teachers apply, and to specify how pupils' needs are considered when teaching technology education on a given topic. The overall study used a mixed-methods approach to the question how pupils’ needs are characterized by themselves and by their teachers, and how they were taken into account in a lesson adapted and delivered by the teachers. In the sub-study presented here, participating primary school teachers were interviewed about their consideration of pupils’ needs whilst planning and conducting a technology education unit on the functionality of robots. The results gained from qualitative content analysis of the interviews indicate that although the anticipation of different needs is considered challenging, teachers possess a substantiate amount of practices and strategies to take them into account. The paper systematizes the practices teachers described in structured interviews within strategies and discusses the contribution of taking basic needs into account for inclusive technology education.}}, author = {{Schröer, Franz and Tenberge, Claudia}}, booktitle = {{Linköping Electronic Conference Proceedings}}, issn = {{1650-3686}}, keywords = {{Technology Education, Inclusion, Basic Needs, Robotics, Mixed Methods, Teachers' Abilities}}, publisher = {{Linköping University Electronic Press}}, title = {{{“They Really Need to Handle, Inspect, and Experience Things”}}}, doi = {{10.3384/ecp213.1455}}, volume = {{218}}, year = {{2026}}, } @article{66092, abstract = {{ DNA origami nanostructures (DONs) have promising applications in biomedicine and biosensing, which often require their efficient binding to target cells. By immobilizing the glycopeptide antibiotic vancomycin on DONs, DON binding to Gram‐positive and Gram‐negative bacteria can be facilitated. Here, we investigate how this multivalent binding is affected by the number and arrangement of the vancomycin modifications on two‐dimensional DONs. We find that for both Gram‐positive Bacillus subtilis and Gram‐negative Escherichia coli , binding increases with the number of vancomycin modifications per DON. In general, binding to E. coli is stronger than to B. subtilis , which may be attributed to differences in the architectures of the cell envelopes. Interestingly, for both bacteria, the total number of vancomycin modifications appears to be more important than their arrangement, as DONs with 18 vancomycin molecules on one side show similar binding as DONs with 18 vancomycin molecules distributed over both sides. This enables the attachment of multiple probe molecules to the vancomycin‐free side of the DONs for enhancing detection efficiency without compromising binding affinity. These results may thus provide guidelines for the design and synthesis of vancomycin‐modified DONs for antimicrobial drug delivery and pathogen detection. }}, author = {{Coşkuner Leineweber, Özge and Hofmann, Ulrike and Grundmeier, Guido and Zhang, Yixin and Keller, Adrian Clemens}}, issn = {{1439-4227}}, journal = {{ChemBioChem}}, number = {{13}}, publisher = {{Wiley}}, title = {{{Vancomycin‐Mediated Binding of DNA Origami Nanostructures to Gram‐Positive and Gram‐Negative Bacteria}}}, doi = {{10.1002/cbic.70436}}, volume = {{27}}, year = {{2026}}, } @misc{66090, author = {{Thomas, Sven}}, booktitle = {{Jahrbuch Technikphilosophie}}, publisher = {{Nomos}}, title = {{{Discourses on Discursive Machines.

We first apply clustering analysis to the learnt representation of backchannels and fillers, and have found increased silhouette scores in representations from fine-tuned models, which suggests that fine-tuning enables LMs to distinguish the nuanced semantic variation in different backchannel and filler use.
