For years, I've had a test-card at the start of my slides. Before I start my talk, I can immediately see if the aspect ratio is wrong, colours are off, or any other visual issues with the presentation.

\nA few years ago I was invited to give a talk and was assured that the venue was set up for audio as well as video. I dutifully filled my slides with with demo videos containing sound. None of them worked. Somewhere between the HDMI output of the presentation laptop and the speakers, the audio went AWOL.
\nEver since then, I've placed an audio test slide at the start of my presentations. There's a good range of videos on YouTube - pick one you like, embed it into your slides, and play it before your talk starts.
\nOver the years, I've found the following \"bugs\" with event AV setups:
\nWhether events are professionally run or community managed, you can never guarantee that sound will work. Add subtitles to your videos. If possible, add a sign-language interpreter. And, if all else fails, hold your microphone to your laptop's speakers.

\nBy default, most Mastodon instances won't periodically poll your account information just to see if you've updated it. So how does the information get from your server to your followers' servers?
\nThis wasn't immediately obvious to me, but I got a clue from reading Evan Prodromou's book on ActivityPub:
\n\nThe Update activity type is for updating the properties of an object represented by the object property.
\nThe most common types of objects that can be updated are content objects, like Note or Image. Actor types (like Person) and Question activity types can also be updated.
Aha!
\nYou need to craft an Update message which has as its object the new user information. That needs to be sent to the inbox of all your followers.
Something like this:
\n{\n \"@context\": \"https://www.w3.org/ns/activitystreams\",\n \"actor\": \"https://example.com/user\",\n \"id\": \"6a9162a6-a8e5-ca0f-9c08-8e6b814acef8\",\n \"published\": \"2026-08-31T12:34:56+01:00\",\n \"to\": \"https://www.w3.org/ns/activitystreams#Public\",\n \"type\": \"Update\",\n \"object\": {\n \"@context\": [\n \"https://www.w3.org/ns/activitystreams\",\n \"https://w3id.org/security/v1\"\n ],\n \"id\": \"https://example.com/user\",\n \"name\": \"My new name\",\n \"summary\": \"A brand new description!\",\n \u2026\n },\n}\nObviously the full user information is a bit more than that - it will include inbox details, public keys, avatars, etc. The published property in the Update activity should be when you changed your details - not when the account was created.
Once that was sent, Mastodon immediately reflected the changes.
\nThis blog post was funded in part by the work I'm doing for my NLnet NGI0 grant to develop ActivityBot.

Here's a fascinating story from California where an robotaxi was redirected from its intended destination and, instead, delivered its misbehaving passengers to the police.
\n\nThe 15-year-old passengers were riding in a driverless autonomous car around San Mateo Monday afternoon. The teens drank alcohol inside the Waymo taxi and shot Orbeez beads with a toy gun toward other vehicles.
\nA Waymo employee, who was remotely monitoring the car, tricked the unruly teenagers, authorities said. The employee told the young passengers that the Waymo was having mechanical issues and needed to stop.
\nUnknown to the teens, the employee had also called the San Mateo Police Department to report that a gun was firing from the car.
\nHere's how Waymo tricked unruly teen passengers in San Mateo
Is that OK?
\nKids shooting (albeit fake) guns out of cars is bad. I've no problem with the long arm of the law feeling their collars.
\nBut what sort of reasonable expectation of privacy do you have when you jump into a driverless car?
\nIf you have a blazing row with your partner while sat in the back of a black cab, the driver's going to hear, right? There's no privacy expectation although you might rely on their discretion.
\nTake a phone call and arrange a drug deal, the driver might turn you in to the police. They're not a confidant, are they?
\nKiss someone you shouldn't and you accept the risk that the driver might both notice and care.
\nBut when there's no driver, there's no risk of your privacy being invaded is there?
\n\nNine former Tesla employees told Reuters that Tesla workers shared customer videos and images recorded by in-car cameras between 2019 and 2022.
\nTesla Workers Shared 'Intimate' Videos Recorded By In-Car Cameras
Ah.
\nI don't know how Waymo was alerted to the problems in the car. Perhaps someone called them and reported the numberplate. Perhaps the car heard raised voices and sent an alert. Perhaps Waymo just regularly drops in on all its customers.
\nRummaging through Waymo's various privacy policies eventually leads to this rather ambiguous page which describes how they monitor the inside of their vehicles.
\n\nOur autonomous vehicles are equipped with an advanced suite of sensors \u2013 including cameras and microphones \u2013 that act as the 'eyes and ears' of our Waymo Driver.
\nCameras inside the car\nCameras are a way for us to make sure that your trip goes smoothly. Among other things, we may use cameras to:
\n\n
\n- Make sure that cars are clean
\n- Find lost items
\n- Provide help in case of emergency
\n- Check that in-car rules are being followed [Emphasis added]
\n- Improve products and services
\n- Promote safety and security [Emphasis added]
\nOur Support team may review video under certain circumstances, including after an issue is brought to our attention. Occasionally, in more urgent circumstances, Support may access live video during a trip.
\nMicrophones inside the car\nThe microphones inside the car are only on during voice calls with Rider Support or when you actively choose to enable microphones inside the car.
To me, that sounds like riders' voices aren't automatically sent back to the mothership. Indeed, they're at pains to say:
\n\nWaymo vehicles also have a number of sensors, including our audio-detection system used to detect police and emergency vehicle sirens. Waymo has implemented technical and procedural safeguards designed to limit the collection of any human voice data from these microphones.
So there is some acknowledgement of privacy - for our voices at least. Meanwhile, passengers are all watched over by machines of loving grace or, at the very least, fallible humans with prurient interests.
\nAbout a decade ago, people were theorising that a driverless cars would one day deliver to you a rider who died on the journey. I don't think that's happened yet - instead, we have cars watching what what we do. Silently judging us picking our noses. Examining our body language for signs of stress. Tracking our breathing patterns and heart-rates to ensure we aren't going to cause damage to the vehicle.
\nNot listening though. That would be a step too far.
\nBesides, who needs to use a microphone when you've got a high-resolution camera backed by AI?
\n\nJust as I finished writing this post, a story broke about how a Waymo pulled over and called the police on riders who had \"ghost gun\". The company said it alerted the authorities after detecting a terms of service violation.
\nOf course, it didn't say how it detected that!
\nI also find it curious that in both cases, the alleged perpetrators were juveniles. Maybe children have less of a right to privacy than adults?
\nI guess when you ride alone, you ride with a snitch.

I'm preparing a lecture for tomorrow morning about various population sequencing projects, from HapMap to 1000 Genomes to ExAC to GnomAD. While preparing to teach the International HapMap Project, I paused for a sec at CEU, a French acronym attached to Utah families from the initial phase of the HapMap project.
Through my 20-something years in this field I think I've been really sloppy about throwing around different terms for these samples. CEU. CEPH. Coriell. What's the story here? I did a little digging.
Let's step back to the 80s and 90s. Jean Dausset shared the 1980 Nobel Prize with Baruj Benacerraf and George Snell for research on immune regulation, including Dausset's work on HLA. Proceeds from paintings bequeathed by H\u00e9l\u00e8ne Anavi helped him establish the Centre d'\u00c9tude du Polymorphisme Humain in Paris (foundation biography, earlier account). CEPH opened in 1984 and became a foundation in 1993. Dausset founded it with Daniel Cohen, Howard Cann, and Mark Lathrop (history, overview).
![\"\"](\"https://substackcdn.com/image/fetch/$s_!UxP-!,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F8c6afafd-26ed-4e45-b26d-069d8af839ab_379x407.png\")
CEPH distributed DNA from the same large families to mapping laboratories and combined their genotypes into one database. They created EBV-transformed lymphoblastoid cell lines to provide a renewable source of DNA. The Coriell Institute holds records from 61 families and 809 people. From CEPH:
The Centre d'Etude du Polymorphisme Humain (CEPH), Foundation Jean Dausset, Paris, France has contributed its collection of 61 reference families to the Repository. The CEPH collection includes families collected by R. White (Utah), J. Dausset (French), J. Gusella (Venezuelan), and J. Egeland (Amish). There are a total of 809 individuals accounting for 832 pedigree positions in the reference families.
The first comprehensive genetic map of human chromosomes in 1987 used 21 families and 403 loci, including 393 RFLPs (paper). CEPH described the collaboration in 1990; the 1992 NIH/CEPH map contained 1,416 loci.
CEPH lists 48 Utah families, 10 French, one Amish, and two Venezuelan (breakdown); Utah currently counts 47 pedigrees. Large families and genealogical records helped attract Ray White to Utah (history, Prescott et al.). The wider Utah Mormon population (aka The Church of Jesus Christ of Latter-day Saints) had very low inbreeding and resembled northern European populations (O'Brien et al.). CEU covers one narrow ancestry sample and can't represent all Europeans.
The Coriell Institute in Camden, New Jersey, USA maintains the NIGMS repository and separate NHGRI collections. CEPH/Utah materials are distributed through NIGMS. Coriell describes their use in their HapMap collection. GM12878 identifies an EBV-transformed B-cell line; NA12878 identifies derived DNA. Coriell holds lines from 153 CEU grandparents.
CEU is the population code for \"Utah residents (CEPH) with Northern and Western European ancestry\" (IGSR). The CEU \"Central EUrope\" wording is a backronym. The HapMap project was described in 2003. Phase I finished with 269 people including 30 CEU trios, 30 YRI trios, 45 unrelated CHB participants, and 44 JPT participants.
HapMap kept the CEPH label so new genotypes could be combined with earlier results. From Rotimi et al.:
The CEPH samples studied for the Project were collected in 1980 from residents of Utah whose recent ancestors came primarily from northern and western Europe. The label CEPH is an acronym for the Centre d'Etude Polymorphisme Humain, the organization that originally collected the samples. Cell lines for the CEPH samples have been publicly available since 1992 from the Coriell Institute. [\u2026] HapMap investigators wanted to build on this valuable body of existing data, and thus chose to use a subset of these same samples to develop the HapMap. Although the original complete CEPH sample set includes some samples from individuals in France and Venezuela and individuals identified as Amish from Pennsylvania, only samples from the Utah CEPH donors were used for the Project. Although the CEPH population is the only one whose samples are included in the HapMap to be known by an acronym, investigators chose to retain this population label for the Project so that the HapMap data could be readily integrated with preexisting data from other studies of these samples without engendering confusion within the scientific community.
Investigators recontacted Utah donors by mail, telephone, and home visits. Utah researchers retained confidential identity links. Those links stayed in Utah, and that prevented Coriell and HapMap from returning individual results or processing individual withdrawal (for more details on this see the HapMap ethics paper). Current discourse in 2026 concerns deriving iPSCs from samples collected under consent forms that predated the technology (see this 2026 preprint).
NA12878 belongs to CEPH pedigree 1463. She is the adult offspring of NA12891 and NA12892, and mother of 11 in the 17-member Platinum Genomes pedigree. Her DNA became the Genome in a Bottle pilot and NIST RM 8398. From GM12878 we got a 2018 MinION human-genome assembly using ultralong nanopore reads (preprint, final paper). Researchers can order the cell line or DNA from the Coriell Institute.
TL;DR? CEPH organized the families, Utah supplied most of them, Coriell distributes the materials, and CEU specifically names the HapMap subset.

Thus when the early transition metal is Ti (Cp = cyclopentadienyl) it forms only the six membered ring shown below (X=S), with none of the five-membered/four-sulfur ring present. However, other central and later transition period metals only form four-sulfur rings.[1]
\n![\"\"](\"https://www.ch.ic.ac.uk/rzepa/blog/wp-content/uploads/2026/09/Cp2TiS5.svg\")
\nThe effect was attributed to the degree of overlap\u00a0of a localised sulfur p-orbital with a vacant Ti d-orbital as shown below (Figure 1. click on the diagram to get a 3D model).
![\"\"](\"https://www.ch.ic.ac.uk/rzepa/blog/wp-content/uploads/2026/09/TiS5-NBO_mo8490.jpg\")
\nFigure 1. Overlap between a sulfur p-donor and a titanium d-acceptor.
One quantative estimate of the magnitude of the effect can be obtained using the NBO7 method[2], which provides a value for the perturbation interaction energy between the filled donor orbital (the S p-orbital) and the empty acceptor orbital (the Ti d-orbital) as a so-called E(2) energy. Thus in the article[1] the E(2) energy for the Ti six-membered complex shown above was reported as 21.2 kcal/mol (Table below) whereas for the analogous five-ring (for which the overlap between the two orbitals is less good) the value was 11.0 kcal/mol. This effect can be related [1] to the relative (free energy) stability of the product complex in the above reaction.
\nThe question now arises whether the effect can be “optimised” by changing some of the ring atoms from S to another. In fact eight crystal structures have been reported with such substitutions (Table) and so here the NBO7 analysis is repeated for these systems and a few other as yet unreported examples.

The effect identified previously[1] which is responsible for the preference of early transition metals such as Ti to form polysulfide rings with five sulfurs rather than four appears to reach a maximum for the known species X=AsMe (Figure 2) or the as yet unmade molecule with X=PMe.
\n\u2020The equatorial isomer for X=NMe is a remarkable ~10.6 kcal/mol higher in free energy.[26] whereas for X=AsMe it is reduced to 4.59 kcal/mol. This is probably due to the angle subtended at N/As, which is 117.7\u00b0 for N and 103.6\u00b0 for As, which may also propagate to the values of the dihedral angle. \u2021The NBO7 localisation search terminated unsuccessfully after considering 100000 bonding patterns.
\nFor years, I've had a test-card at the start of my slides. Before I start my talk, I can immediately see if the aspect ratio is wrong, colours are off, or any other visual issues with the presentation.

\nBy default, most Mastodon instances won't periodically poll your account information just to see if you've updated it. So how does the information get from your server to your followers' servers?
\nThis wasn't immediately obvious to me, but I got a clue from reading Evan Prodromou's book on ActivityPub:
\n\nThe Update activity type is for updating the properties of an object represented by the object property.
\nThe most common types of objects that can be updated are content objects, like Note or Image. Actor types (like Person) and Question activity types can also be updated.
Aha!
\nYou need to craft an Update message which has as its object the new user information. That needs to be sent to the inbox of all your followers.
Something like this:
\n{\n \"@context\": \"https://www.w3.org/ns/activitystreams\",\n \"actor\": \"https://example.com/user\",\n \"id\": \"6a9162a6-a8e5-ca0f-9c08-8e6b814acef8\",\n \"published\": \"2026-08-31T12:34:56+01:00\",\n \"to\": \"https://www.w3.org/ns/activitystreams#Public\",\n \"type\": \"Update\"\n \"object\": {\n \"@context\": [\n \"https://www.w3.org/ns/activitystreams\",\n \"https://w3id.org/security/v1\"\n ],\n \"id\": \"https://example.com/user\",\n \"name\": \"My new name\",\n \"summary\": \"A brand new description!\",\n \u2026\n },\n}\nObviously the full user information is a bit more than that - it will include inbox details, public keys, avatars, etc. The published property in the Update activity should be when you changed your details - not when the account was created.
Once that was sent, Mastodon immediately reflected the changes.
\nThis blog post was funded in part by the work I'm doing for my NLnet NGI0 grant to develop ActivityBot.

Now that I'm in my final year before turning 60, I thought it was a good time to learn from others, take on board new ideas, inspire one another and share that with everyone around us. With an emphasis on each other's 'long-term perspectives'. For me, these are transparency, reliability, resilience, accessibility and connection. I have reached out (and will continue to do so) to a few people I didn't really know, who have piqued my curiosity, and with whom I'd like to have a conversation. The first connection I made was on 26 August 2026, with Peter Kuipers Munneke, a meteorologist.
\nAt the last minute, Peter changed the destination I was travelling to \u2013 I was now heading to the \"Kromme Rijn\" tram stop, linked to the spot where people and goods were once transported in 'large volumes' across the water by towboat. From this stop, we walked via Amelisweerd to \"De Veldkeuken\", where we rounded off our conversation with a fresh lemonade. Building on my introduction about the 'long-term principles' and the stage of life I'm currently at, Peter spoke about what drives him.
\nAfter a very brief stint studying Urban and Regional Planning (chosen because he couldn't decide between humanties/arts and sciences, and it seemed like a very broad education), he eventually went on to study Physics. The latter decision was based on the advice of his old maths' teacher, who told him that with a physics degree, you could go on to do anything. And indeed, Peter's fellow students have ended up in a wide variety of fields. Which is quite remarkable, actually, because I myself also wanted to continue the diversity of my secondary school curriculum, and was advised by my school counsellor to study Materials Science (that way, you'd at least have chemistry, physics and maths, he said).\nWhilst studying in Utrecht, he also took a few modules in science communication and became particularly interested in the (macroscopic) world around him \u2013 far more so than in anything (sub-)atomic. He was much more keen to be able to explain the blue of the sky and the white of the clouds.
\nAfter completing his PhD research (on the interaction between ice caps and the climate) and a long postdoctoral position (also in Utrecht), a vacancy came up at the NOS about twelve years ago to be responsible for the daily weather forecast two days a week. And now, well: who doesn't know Peter as a weather presenter? It's an ideal combination: spending 60 per cent of your time conducting research as a meteorologist and glaciologist, and 40 per cent sharing some of that acquired knowledge with the general public. And for him, it brought together his interest in the macroscopic world with science communication. Because that is precisely one of Peter's two driving forces \u2013 making research (knowledge) accessible. His strength \u2013 which came across particularly well during the NOS Live broadcast on 12 August 2026 covering the (partial) solar eclipse \u2013 is his ability to explain a 'rather complicated subject' in a way that's understandable and straightforward. That's important, and it's also enjoyable to do. In doing so, he can make the world a little wiser and enable people to make choices based on facts.\nHe now explains things in simple terms to what we call the general public, but sometimes also to a specific target audience, such as a primary school class, a group of first-year higher professional education students studying Forestry and Nature Conservation, or library staff. That is, in fact, where we first met \u2013 at the national library conference on 18 June 2026, where Peter gave a talk. It is a driving force for him, and it comes naturally to him, because he has been building up his knowledge of the climate for twenty years and knows what he knows.
\nAnd with that, we touch on the core \u2013 but also the dilemma \u2013 of Peter's second driving force (which he feels very deeply), where there is a certain tension. He is keen to share facts so that other people can gain a clear understanding of the choice that lies ahead. The role of science as an 'honest broker approach' \u2013 you lay everything on the table and leave it to the other person to draw their own conclusions. He has strong views on how the world works and how we are collectively destroying it, on how some people are deliberately enriching themselves at the expense of our world, and believes we should stop overconsumption. But when he speaks \u2013 as he did on the subject of public libraries \u2013 he takes a more nuanced view, because he is also aware that it is important to remain credible and to continue seeking connection.
\nWe talked about the lovely spot where we were walking, and the fact that the A12 motorway (which you can hear quite clearly) had been prevented from being widened, which is why we were able to walk there in the first place. It's good that there are people who stand up against such developments, but that doesn't mean you can always do this yourself. Your position (and with it your other motivation, accessibility) then comes under pressure. So sometimes you have to put a motivation or long-term goal on hold or set it aside because something else takes precedence. Or, as I realized afterwards, it might be something like the tension between openness and security \u2013 both are important and valid, and you need a narrative that brings them together.\nThat also brings us to some of the guiding principles he shared with the audience at the national library conference, namely to ensure that you share facts (and make them accessible), and continue to seek connection (he put it as 'be apolitical'). Seeking connection sometimes means keeping quiet \u2013 as a library, stay 'in the middle'. And yet \u2026 Peter wants the word 'fight' to feature in his eulogy in one way or another.
\nConducting research and sharing a great deal of it with society is wonderful work; it's remarkable how the two roles Peter holds complement each other so beautifully. Inspiration? It's hardly surprising, of course, that Peter draws his from nature. He walks a lot, and has even recommended the long-distance walking route 'het Groene Hart' to me, because it visits my own Delftse Hout as well.

\nUnsere monatliche Rubrik zu aktuellen Veranstaltungen rund um Open Research.
\nAnmerkung zu dieser Rubrik: Das Open Research Office Berlin erstellt monatlich eine \u00dcbersicht \u00fcber Termine und Veranstaltungen zu Open Access und Open Research in Berlin bzw. an Berliner Einrichtungen. Der Fokus liegt dabei auf unseren Partnereinrichtungen und auf Veranstaltungen, die sich an die \u00d6ffentlichkeit richten bzw. die offen sind f\u00fcr Angeh\u00f6rige der Wissenschafts- und Kulturerbeeinrichtungen in Berlin. Wir erg\u00e4nzen diese Liste gerne (Info bitte via Mail ans OROB).\n\n
Wie gehen Einrichtungen des Kulturerbes mit den Zeugnissen der Vergangenheit um? Nutzen sie diese, um bestimmte Sichtweisen historischer Entwicklungen zu st\u00fctzen, oder \u00fcberlassen sie die Bewertung den Nutzenden und erm\u00f6glichen vor allem den Zugang zu den Quellen? W\u00e4hrend Museen mit kuratierten Ausstellungen h\u00e4ufig st\u00e4rker interpretierend arbeiten, verstehen sich Archive und Bibliotheken traditionell eher als Einrichtungen, die sich auf den Zugang zu ihren Best\u00e4nden konzentrieren. Diese Rollenverteilung ger\u00e4t jedoch unter Druck, wenn es um ein schwieriges Erbe \u2013 etwa rassistische oder antisemitische Zeugnisse \u2013 geht: Archive werden kritisiert, wenn sie scheinbar ungefilterten Zugang gew\u00e4hren, w\u00e4hrend zugleich geschichtspolitische Eingriffe in Kulturerbeeinrichtungen kontrovers diskutiert werden.
\n2026 findet die dritte Ausgabe des gro\u00dfen OER-Fachtags von ORCA.nrw statt. Freuen Sie sich \u00fcber den Tag hinweg auf eine spannende Keynote, Projektvorstellungen, Workshops und viel Austausch & Vernetzung!
\nIm Vortrag wird, ankn\u00fcpfend an das Blockchain-Projekt f\u00fcr digitale Zeugnisse, die EUDI-Wallet thematisiert. Die Historie der Entwicklung dieser digitalen Brieftasche auf EU-Ebene wird vorgestellt und die Funktionen und M\u00f6glichkeiten sowie Detailinformationen zur Sicherheit werden erl\u00e4utert. Der aktuelle Stand der Entwicklung wird betrachtet und in Form einer Demo wird die Nutzung an einem konkreten Beispiel veranschaulicht. Nach einem Blick auf zuk\u00fcnftige Entwicklungen im Bereich \"Digitaler Identit\u00e4ten\", wie z. B. Post-Quanten-Verschl\u00fcsselung oder Alternative Biometrische Identifikationsverfahren (AuBi) schlie\u00dft der Abend mit Raum f\u00fcr Diskussionen \u00fcber die Technologie und deren Nutzung.
\nDer Einsatz von KI Technologien erstreckt sich zunehmend auf zentrale Bereiche politischer Steuerung, von der \u00f6ffentlichen Verwaltung und der Umweltpolitik bis hin zu Grenzregimen und wirtschaftlicher Regulierung. Dabei ver\u00e4ndern sie nicht nur Verfahren; es verschieben sich Machtkonstellationen, Verantwortung und politische Handlungsspielr\u00e4ume. Das Symposium mit \u00f6ffentlicher Paneldiskussion diskutiert KI als systemische Herausforderung f\u00fcr Demokratie und Rechtsstaat. Die Veranstaltung bietet kurze Einf\u00fchrungen in verschiedene Schwerpunkte unserer Forschung und erm\u00f6glicht eine kollaborative Plattform zur Diskussion der systemischen Kosten algorithmischer Governance f\u00fcr demokratische Strukturen. Dies schafft einen offenen Raum f\u00fcr Austausch mit politischen Entscheidungstr\u00e4ger*innen, Vertreter*innen von NGOs, Forschenden sowie allen, die an der Zukunft einer digitalen Gesellschaft interessiert sind.
\nDas Digitale ist ein gro\u00dfes Versprechen: Physische R\u00e4ume und pers\u00f6nliche Speichermedien scheinen ganz \u00fcberfl\u00fcssig zu werden, die Cloud soll ortsunabh\u00e4ngigen, schnellen Zugriff und unbegrenzten Speicherplatz erm\u00f6glichen. Aber was kostet das, welche L\u00f6sungen sind sicher und umweltvertr\u00e4glich?\u00a0Gemeinsam mit bestandserhaltenden Einrichtungen und Vertreter:innen aus Wissenschaft und Forschung wollen wir das Versprechen des Digitalen \u00fcberpr\u00fcfen und konstruktive Vorschl\u00e4ge zur longue dur\u00e9e des digitalen Erbes entwickeln. Es sprechen u.v. a.: Frank Scholze (Deutsche Nationalbibliothek), Richard Ovenden (Bodleian Library Oxford) und Petra Gehring (Rat f\u00fcr Informationsinfrastrukturen).
\nDas Open Science Forum Mitteldeutschland 2026 bringt am 5. Oktober Interessierte zu einem offenen Austausch \u00fcber Open Science als Gestaltungsaufgabe zusammen. Wir widmen uns der Frage, welche Rolle wissenschaftsunterst\u00fctzende Einrichtungen spielen, wenn es um neue Ans\u00e4tze in der Forschungsbewertung, nachhaltige Infrastrukturen und digitale Souver\u00e4nit\u00e4t im Spannungsfeld geopolitischer Entwicklungen geht.
\nIn Archiven, Bibliotheken und anderen Ged\u00e4chtniseinrichtungen lagern bundesweit gef\u00e4hrdete Originale, die Meinungsvielfalt, Rechtsordnungen, historische Entwicklungen und politisches Handeln dokumentieren. Der Erhalt dieser \u00dcberlieferungen ist Grundvoraussetzung f\u00fcr eine quellen- und faktenbasierte Forschung, eine historische Aufarbeitung sowie die Sichtbarmachung gesellschaftlicher Mehrstimmigkeit und Diskurse. Originalerhalt ist grundlegender Bestandteil der Informationssicherung und ein wichtiger Beitrag zu einer lebendigen, urteilsf\u00e4higen und wehrhaften Demokratie \u2013 insbesondere angesichts der zunehmenden Bedrohung durch hybride Desinformation und andere demokratiegef\u00e4hrdende Entwicklungen.
\nDie FDM-Sprechstunde Humanities@NFDI ist eine Online-Beratung f\u00fcr Studierende, Forschende oder Mitarbeitende aus Forschungs- und Sammlungsinstitutionen zu allen Fragen rund um das Forschungsdatenmanagement. Expert:innen aus den geisteswissenschaftlichen NFDI-Konsortien NFDI4Memory, NFDI4Culture, NFDI4Objects und Text+ stehen f\u00fcr Ihre Fragen zu allen Themen rund ums Forschungsdatenmanagement bereit. Bei Bedarf k\u00f6nnen Einzelgespr\u00e4che in Breakoutr\u00e4umen vertieft werden.
\nIncreasing consolidation and commercial control over all aspects of knowledge comes at a cost. This year's theme challenges us to consider the financial, human, and environmental costs of creating, sharing, and sustaining knowledge\u2014particularly when these costs are driven by private rather than public interests. Last year's theme of \"Who owns our knowledge?\" reflected on the reality of commercial ownership of knowledge. This year's theme will reckon with the costs of that reality and avenues for reclaiming control of these systems meant to serve the public interest.
\nDer Aktionstag \"Forschungsdaten@BUA\" l\u00e4dt erstmals Forschende der Berlin University Alliance herzlich ein, \u00fcber den Umgang mit Forschungsdaten ins Gespr\u00e4ch zu kommen, sich auszutauschen und zu vernetzen. Ziel ist es, Best Practices sichtbar zu machen, Erfahrungen auszutauschen und den Dialog \u00fcber den Umgang mit Forschungsdaten \u00fcber die vier BUA-H\u00e4user hinweg auszubauen.
\nIn diesem Workshop lernen die Teilnehmenden datenschutzkonforme KI-Anwendungen und Einsatzm\u00f6glichkeiten kennen, die neue Wege f\u00fcr die Nachnutzung von Forschungsdaten erm\u00f6glichen und zur Verbesserung von Datenqualit\u00e4t, Metadatenverf\u00fcgbarkeit und Zug\u00e4nglichkeit beitragen. Mithilfe konkreter Anwendungsf\u00e4lle aus der Forschung werden die rechtssicheren Einsatzm\u00f6glichkeiten der KI im Datenlebenzyklus vorgestellt.
\nDer Workshop f\u00fchrt in die Grundfunktionen von OpenRefine ein und zeigt an konkreten Anwendungsf\u00e4llen, wie Forschende tabellarische Datens\u00e4tze bereinigen, strukturieren und anreichern k\u00f6nnen. Dabei werden auch geskriptete Bearbeitungsschritte sowie der Import und Export verschiedener Datenformate (CSV, XML, JSON) behandelt. OpenRefine erm\u00f6glicht nicht nur einen schnellen \u00dcberblick \u00fcber gro\u00dfe Datens\u00e4tze, sondern hilft vor allem bei heterogenen und historisch gewachsenen Datens\u00e4tze, die oft inkonsistente Metadaten aufweisen.
\nDer Workshop gibt einen \u00dcberblick \u00fcber ELN-Konzepte, zeigt relevante Forschungsdatenmanagement-Aspekte auf und bietet eine praktische Einf\u00fchrung.
\nIm Rahmen dieses Hands-on-Workshops werden Konzepte zum effizienten, reproduzierbaren und nachvollziehbaren Arbeiten mit Forschungsdaten vermittelt. Ziel ist es, die Teilnehmenden mit verschiedenen Werkzeugen vertraut zu machen und das Bewusstsein f\u00fcr Computational Thinking, Automatisierung sowie die Optimierung eigener Arbeitsprozesse zu sch\u00e4rfen.
\nIm Forschungsalltag stehen Forschende regelm\u00e4\u00dfig vor urheberrechtlichen Fragen: Welche Inhalte darf ich in meiner Arbeit verwenden? Unter welchen Bedingungen kann ich Daten und Materialien offen teilen? Wie gehe ich mit KI-Tools und deren Trainingsdaten rechtssicher um? Dieser Workshop bietet praxisnahe Orientierung f\u00fcr den sicheren Umgang mit gesch\u00fctzten Inhalten und Lizenzen in der wissenschaftlichen Arbeit.
\nIn our three-part workshop series, we explore the relationship between the technical aspects, practical applications and critical reflection of the use of AI in research data management. Participants will learn about various AI tools and use cases for research data management, test, and develop criteria for the meaningful and responsible use of AI in their own work.

\nBy default, most Mastodon instances won't periodically poll your account information just to see if you've updated it. So how does the information get from your server to your followers' servers?
\nThis wasn't immediately obvious to me, but I got a clue from reading Evan Prodromou's book on ActivityPub:
\n\nThe Update activity type is for updating the properties of an object represented by the object property.
\nThe most common types of objects that can be updated are content objects, like Note or Image. Actor types (like Person) and Question activity types can also be updated.
Aha!
\nYou need to craft an Update message which has as its object the new user information. That needs to be sent to the inbox of all your followers.
Something like this:
\n{\n \"@context\": \"https://www.w3.org/ns/activitystreams\",\n \"actor\": \"https://example.com/user\",\n \"id\": \"6a9162a6-a8e5-ca0f-9c08-8e6b814acef8\",\n \"published\": \"2026-08-31T12:34:56+01:00\",\n \"to\": \"https://www.w3.org/ns/activitystreams#Public\",\n \"type\": \"Update\",\n \"object\": {\n \"@context\": [\n \"https://www.w3.org/ns/activitystreams\",\n \"https://w3id.org/security/v1\"\n ],\n \"id\": \"https://example.com/user\",\n \"name\": \"My new name\",\n \"summary\": \"A brand new description!\",\n \u2026\n },\n}\nObviously the full user information is a bit more than that - it will include inbox details, public keys, avatars, etc. The published property in the Update activity should be when you changed your details - not when the account was created.
Once that was sent, Mastodon immediately reflected the changes.
\nThis blog post was funded in part by the work I'm doing for my NLnet NGI0 grant to develop ActivityBot.

Here's a fascinating story from California where an robotaxi was redirected from its intended destination and, instead, delivered its misbehaving passengers to the police.
\n\nThe 15-year-old passengers were riding in a driverless autonomous car around San Mateo Monday afternoon. The teens drank alcohol inside the Waymo taxi and shot Orbeez beads with a toy gun toward other vehicles.
\nA Waymo employee, who was remotely monitoring the car, tricked the unruly teenagers, authorities said. The employee told the young passengers that the Waymo was having mechanical issues and needed to stop.
\nUnknown to the teens, the employee had also called the San Mateo Police Department to report that a gun was firing from the car.
\nHere's how Waymo tricked unruly teen passengers in San Mateo
Is that OK?
\nKids shooting (albeit fake) guns out of cars is bad. I've no problem with the long arm of the law feeling their collars.
\nBut what sort of reasonable expectation of privacy do you have when you jump into a driverless car?
\nIf you have a blazing row with your partner while sat in the back of a black cab, the driver's going to hear, right? There's no privacy expectation although you might rely on their discretion.
\nTake a phone call and arrange a drug deal, the driver might turn you in to the police. They're not a confidant, are they?
\nKiss someone you shouldn't and you accept the risk that the driver might both notice and care.
\nBut when there's no driver, there's no risk of your privacy being invaded is there?
\n\nNine former Tesla employees told Reuters that Tesla workers shared customer videos and images recorded by in-car cameras between 2019 and 2022.
\nTesla Workers Shared 'Intimate' Videos Recorded By In-Car Cameras
Ah.
\nI don't know how Waymo was alerted to the problems in the car. Perhaps someone called them and reported the numberplate. Perhaps the car heard raised voices and sent an alert. Perhaps Waymo just regularly drops in on all its customers.
\nRummaging through Waymo's various privacy policies eventually leads to this rather ambiguous page which describes how they monitor the inside of their vehicles.
\n\nOur autonomous vehicles are equipped with an advanced suite of sensors \u2013 including cameras and microphones \u2013 that act as the 'eyes and ears' of our Waymo Driver.
\nCameras inside the car\nCameras are a way for us to make sure that your trip goes smoothly. Among other things, we may use cameras to:
\n\n
\n- Make sure that cars are clean
\n- Find lost items
\n- Provide help in case of emergency
\n- Check that in-car rules are being followed [Emphasis added]
\n- Improve products and services
\n- Promote safety and security [Emphasis added]
\nOur Support team may review video under certain circumstances, including after an issue is brought to our attention. Occasionally, in more urgent circumstances, Support may access live video during a trip.
\nMicrophones inside the car\nThe microphones inside the car are only on during voice calls with Rider Support or when you actively choose to enable microphones inside the car.
To me, that sounds like riders' voices aren't automatically sent back to the mothership. Indeed, they're at pains to say:
\n\nWaymo vehicles also have a number of sensors, including our audio-detection system used to detect police and emergency vehicle sirens. Waymo has implemented technical and procedural safeguards designed to limit the collection of any human voice data from these microphones.
So there is some acknowledgement of privacy - for our voices at least. Meanwhile, passengers are all watched over by machines of loving grace or, at the very least, fallible humans with prurient interests.
\nAbout a decade ago, people were theorising that a driverless cars would one day deliver to you a rider who died on the journey. I don't think that's happened yet - instead, we have cars watching what what we do. Silently judging us picking our noses. Examining our body language for signs of stress. Tracking our breathing patterns and heart-rates to ensure we aren't going to cause damage to the vehicle.
\nNot listening though. That would be a step too far.
\nBesides, who needs to use a microphone when you've got a high-resolution camera backed by AI?
\n\nJust as I finished writing this post, a story broke about how a Waymo pulled over and called the police on riders who had \"ghost gun\". The company said it alerted the authorities after detecting a terms of service violation.
\nOf course, it didn't say how it detected that!
\nI also find it curious that in both cases, the alleged perpetrators were juveniles. Maybe children have less of a right to privacy than adults?
\nI guess when you ride alone, you ride with a snitch.

I'm preparing a lecture for tomorrow morning about various population sequencing projects, from HapMap to 1000 Genomes to ExAC to GnomAD. While preparing to teach the International HapMap Project, I paused for a sec at CEU, a French acronym attached to Utah families from the initial phase of the HapMap project.
Through my 20-something years in this field I think I've been really sloppy about throwing around different terms for these samples. CEU. CEPH. Coriell. What's the story here? I did a little digging.
Let's step back to the 80s and 90s. Jean Dausset shared the 1980 Nobel Prize with Baruj Benacerraf and George Snell for research on immune regulation, including Dausset's work on HLA. Proceeds from paintings bequeathed by H\u00e9l\u00e8ne Anavi helped him establish the Centre d'\u00c9tude du Polymorphisme Humain in Paris (foundation biography, earlier account). CEPH opened in 1984 and became a foundation in 1993. Dausset founded it with Daniel Cohen, Howard Cann, and Mark Lathrop (history, overview).
CEPH distributed DNA from the same large families to mapping laboratories and combined their genotypes into one database. They created EBV-transformed lymphoblastoid cell lines to provide a renewable source of DNA. The Coriell Institute holds records from 61 families and 809 people. From CEPH:
The Centre d'Etude du Polymorphisme Humain (CEPH), Foundation Jean Dausset, Paris, France has contributed its collection of 61 reference families to the Repository. The CEPH collection includes families collected by R. White (Utah), J. Dausset (French), J. Gusella (Venezuelan), and J. Egeland (Amish). There are a total of 809 individuals accounting for 832 pedigree positions in the reference families.
The first comprehensive genetic map of human chromosomes in 1987 used 21 families and 403 loci, including 393 RFLPs (paper). CEPH described the collaboration in 1990; the 1992 NIH/CEPH map contained 1,416 loci.
CEPH lists 48 Utah families, 10 French, one Amish, and two Venezuelan (breakdown); Utah currently counts 47 pedigrees. Large families and genealogical records helped attract Ray White to Utah (history, Prescott et al.). The wider Utah Mormon population (aka The Church of Jesus Christ of Latter-day Saints) had very low inbreeding and resembled northern European populations (O'Brien et al.). CEU covers one narrow ancestry sample and can't represent all Europeans.
The Coriell Institute in Camden, New Jersey, USA maintains the NIGMS repository and separate NHGRI collections. CEPH/Utah materials are distributed through NIGMS. Coriell describes their use in their HapMap collection. GM12878 identifies an EBV-transformed B-cell line; NA12878 identifies derived DNA. Coriell holds lines from 153 CEU grandparents.
CEU is the population code for \"Utah residents (CEPH) with Northern and Western European ancestry\" (IGSR). The CEU \"Central EUrope\" wording is a backronym. The HapMap project was described in 2003. Phase I finished with 269 people including 30 CEU trios, 30 YRI trios, 45 unrelated CHB participants, and 44 JPT participants.
HapMap kept the CEPH label so new genotypes could be combined with earlier results. From Rotimi et al.:
The CEPH samples studied for the Project were collected in 1980 from residents of Utah whose recent ancestors came primarily from northern and western Europe. The label CEPH is an acronym for the Centre d'Etude Polymorphisme Humain, the organization that originally collected the samples. Cell lines for the CEPH samples have been publicly available since 1992 from the Coriell Institute. [\u2026] HapMap investigators wanted to build on this valuable body of existing data, and thus chose to use a subset of these same samples to develop the HapMap. Although the original complete CEPH sample set includes some samples from individuals in France and Venezuela and individuals identified as Amish from Pennsylvania, only samples from the Utah CEPH donors were used for the Project. Although the CEPH population is the only one whose samples are included in the HapMap to be known by an acronym, investigators chose to retain this population label for the Project so that the HapMap data could be readily integrated with preexisting data from other studies of these samples without engendering confusion within the scientific community.
Investigators recontacted Utah donors by mail, telephone, and home visits. Utah researchers retained confidential identity links. Those links stayed in Utah, and that prevented Coriell and HapMap from returning individual results or processing individual withdrawal (for more details on this see the HapMap ethics paper). Current discourse in 2026 concerns deriving iPSCs from samples collected under consent forms that predated the technology (see this 2026 preprint).
NA12878 belongs to CEPH pedigree 1463. She is the adult offspring of NA12891 and NA12892, and mother of 11 in the 17-member Platinum Genomes pedigree. Her DNA became the Genome in a Bottle pilot and NIST RM 8398. From GM12878 we got a 2018 MinION human-genome assembly using ultralong nanopore reads (preprint, final paper). Researchers can order the cell line or DNA from the Coriell Institute.
TL;DR? CEPH organized the families, Utah supplied most of them, Coriell distributes the materials, and CEU specifically names the HapMap subset.

Thus when the early transition metal is Ti (Cp = cyclopentadienyl) it forms only the six membered ring shown below (X=S), with none of the five-membered/four-sulfur ring present. However, other central and later transition period metals only form four-sulfur rings.[1]
\n
\nThe effect was attributed to the degree of overlap\u00a0of a localised sulfur p-orbital with a vacant Ti d-orbital as shown below (Figure 1. click on the diagram to get a 3D model).
\nFigure 1. Overlap between a sulfur p-donor and a titanium d-acceptor.
One quantative estimate of the magnitude of the effect can be obtained using the NBO7 method[2], which provides a value for the perturbation interaction energy between the filled donor orbital (the S p-orbital) and the empty acceptor orbital (the Ti d-orbital) as a so-called E(2) energy. Thus in the article[1] the E(2) energy for the Ti six-membered complex shown above was reported as 21.2 kcal/mol (Table below) whereas for the analogous five-ring (for which the overlap between the two orbitals is less good) the value was 11.0 kcal/mol. This effect can be related [1] to the relative (free energy) stability of the product complex in the above reaction.
\nThe question now arises whether the effect can be “optimised” by changing some of the ring atoms from S to another. In fact eight crystal structures have been reported with such substitutions (Table) and so here the NBO7 analysis is repeated for these systems and a few other as yet unreported examples.

The effect identified previously[1] which is responsible for the preference of early transition metals such as Ti to form polysulfide rings with five sulfurs rather than four appears to reach a maximum for the known species X=AsMe (Figure 2) or the as yet unmade molecule with X=PMe.
\n\u2020The equatorial isomer for X=NMe is a remarkable ~10.6 kcal/mol higher in free energy.[26] whereas for X=AsMe it is reduced to 4.59 kcal/mol. This is probably due to the angle subtended at N/As, which is 117.7\u00b0 for N and 103.6\u00b0 for As, which may also propagate to the values of the dihedral angle. \u2021The NBO7 localisation search terminated unsuccessfully after considering 100000 bonding patterns.

\nThis wasn't immediately obvious to me, but I got a clue from reading Evan Prodromou's book on ActivityPub:
\n\nThe Update activity type is for updating the properties of an object represented by the object property.
\nThe most common types of objects that can be updated are content objects, like Note or Image. Actor types (like Person) and Question activity types can also be updated.
Aha!
\nYou need to craft an Update message which has as its object the new user information. That needs to be sent to the inbox of all your followers.
Something like this:
\n{\n \"@context\": \"https://www.w3.org/ns/activitystreams\",\n \"actor\": \"https://example.com/user\",\n \"id\": \"6a9162a6-a8e5-ca0f-9c08-8e6b814acef8\",\n \"published\": \"2026-08-31T12:34:56+01:00\",\n \"to\": \"https://www.w3.org/ns/activitystreams#Public\",\n \"type\": \"Update\"\n \"object\": {\n \"@context\": [\n \"https://www.w3.org/ns/activitystreams\",\n \"https://w3id.org/security/v1\"\n ],\n \"id\": \"https://example.com/user\",\n \"name\": \"My new name\",\n \"summary\": \"A brand new description!\",\n \u2026\n },\n}\nObviously the full user information is a bit more than that - it will include inbox details, public keys, avatars, etc. The published property in the Update activity should be when you changed your details - not when the account was created.
Once that was sent, Mastodon immediately reflected the changes.
\nThis blog post was funded in part by the work I'm doing for my NLnet NGI0 grant to develop ActivityBot.

Now that I'm in my final year before turning 60, I thought it was a good time to learn from others, take on board new ideas, inspire one another and share that with everyone around us. With an emphasis on each other's 'long-term perspectives'. For me, these are transparency, reliability, resilience, accessibility and connection. I have reached out (and will continue to do so) to a few people I didn't really know, who have piqued my curiosity, and with whom I'd like to have a conversation. The first connection I made was on 26 August 2026, with Peter Kuipers Munneke, a meteorologist.
\nAt the last minute, Peter changed the destination I was travelling to \u2013 I was now heading to the \"Kromme Rijn\" tram stop, linked to the spot where people and goods were once transported in 'large volumes' across the water by towboat. From this stop, we walked via Amelisweerd to \"De Veldkeuken\", where we rounded off our conversation with a fresh lemonade. Building on my introduction about the 'long-term principles' and the stage of life I'm currently at, Peter spoke about what drives him.
\nAfter a very brief stint studying Urban and Regional Planning (chosen because he couldn't decide between humanties/arts and sciences, and it seemed like a very broad education), he eventually went on to study Physics. The latter decision was based on the advice of his old maths' teacher, who told him that with a physics degree, you could go on to do anything. And indeed, Peter's fellow students have ended up in a wide variety of fields. Which is quite remarkable, actually, because I myself also wanted to continue the diversity of my secondary school curriculum, and was advised by my school counsellor to study Materials Science (that way, you'd at least have chemistry, physics and maths, he said).\nWhilst studying in Utrecht, he also took a few modules in science communication and became particularly interested in the (macroscopic) world around him \u2013 far more so than in anything (sub-)atomic. He was much more keen to be able to explain the blue of the sky and the white of the clouds.
\nAfter completing his PhD research (on the interaction between ice caps and the climate) and a long postdoctoral position (also in Utrecht), a vacancy came up at the NOS about twelve years ago to be responsible for the daily weather forecast two days a week. And now, well: who doesn't know Peter as a weather presenter? It's an ideal combination: spending 60 per cent of your time conducting research as a meteorologist and glaciologist, and 40 per cent sharing some of that acquired knowledge with the general public. And for him, it brought together his interest in the macroscopic world with science communication. Because that is precisely one of Peter's two driving forces \u2013 making research (knowledge) accessible. His strength \u2013 which came across particularly well during the NOS Live broadcast on 12 August 2026 covering the (partial) solar eclipse \u2013 is his ability to explain a 'rather complicated subject' in a way that's understandable and straightforward. That's important, and it's also enjoyable to do. In doing so, he can make the world a little wiser and enable people to make choices based on facts.\nHe now explains things in simple terms to what we call the general public, but sometimes also to a specific target audience, such as a primary school class, a group of first-year higher professional education students studying Forestry and Nature Conservation, or library staff. That is, in fact, where we first met \u2013 at the national library conference on 18 June 2026, where Peter gave a talk. It is a driving force for him, and it comes naturally to him, because he has been building up his knowledge of the climate for twenty years and knows what he knows.
\nAnd with that, we touch on the core \u2013 but also the dilemma \u2013 of Peter's second driving force (which he feels very deeply), where there is a certain tension. He is keen to share facts so that other people can gain a clear understanding of the choice that lies ahead. The role of science as an 'honest broker approach' \u2013 you lay everything on the table and leave it to the other person to draw their own conclusions. He has strong views on how the world works and how we are collectively destroying it, on how some people are deliberately enriching themselves at the expense of our world, and believes we should stop overconsumption. But when he speaks \u2013 as he did on the subject of public libraries \u2013 he takes a more nuanced view, because he is also aware that it is important to remain credible and to continue seeking connection.
\nWe talked about the lovely spot where we were walking, and the fact that the A12 motorway (which you can hear quite clearly) had been prevented from being widened, which is why we were able to walk there in the first place. It's good that there are people who stand up against such developments, but that doesn't mean you can always do this yourself. Your position (and with it your other motivation, accessibility) then comes under pressure. So sometimes you have to put a motivation or long-term goal on hold or set it aside because something else takes precedence. Or, as I realized afterwards, it might be something like the tension between openness and security \u2013 both are important and valid, and you need a narrative that brings them together.\nThat also brings us to some of the guiding principles he shared with the audience at the national library conference, namely to ensure that you share facts (and make them accessible), and continue to seek connection (he put it as 'be apolitical'). Seeking connection sometimes means keeping quiet \u2013 as a library, stay 'in the middle'. And yet \u2026 Peter wants the word 'fight' to feature in his eulogy in one way or another.
\nConducting research and sharing a great deal of it with society is wonderful work; it's remarkable how the two roles Peter holds complement each other so beautifully. Inspiration? It's hardly surprising, of course, that Peter draws his from nature. He walks a lot, and has even recommended the long-distance walking route 'het Groene Hart' to me, because it visits my own Delftse Hout as well.

\nUnsere monatliche Rubrik zu aktuellen Veranstaltungen rund um Open Research.
\nAnmerkung zu dieser Rubrik: Das Open Research Office Berlin erstellt monatlich eine \u00dcbersicht \u00fcber Termine und Veranstaltungen zu Open Access und Open Research in Berlin bzw. an Berliner Einrichtungen. Der Fokus liegt dabei auf unseren Partnereinrichtungen und auf Veranstaltungen, die sich an die \u00d6ffentlichkeit richten bzw. die offen sind f\u00fcr Angeh\u00f6rige der Wissenschafts- und Kulturerbeeinrichtungen in Berlin. Wir erg\u00e4nzen diese Liste gerne (Info bitte via Mail ans OROB).\n\n
Wie gehen Einrichtungen des Kulturerbes mit den Zeugnissen der Vergangenheit um? Nutzen sie diese, um bestimmte Sichtweisen historischer Entwicklungen zu st\u00fctzen, oder \u00fcberlassen sie die Bewertung den Nutzenden und erm\u00f6glichen vor allem den Zugang zu den Quellen? W\u00e4hrend Museen mit kuratierten Ausstellungen h\u00e4ufig st\u00e4rker interpretierend arbeiten, verstehen sich Archive und Bibliotheken traditionell eher als Einrichtungen, die sich auf den Zugang zu ihren Best\u00e4nden konzentrieren. Diese Rollenverteilung ger\u00e4t jedoch unter Druck, wenn es um ein schwieriges Erbe \u2013 etwa rassistische oder antisemitische Zeugnisse \u2013 geht: Archive werden kritisiert, wenn sie scheinbar ungefilterten Zugang gew\u00e4hren, w\u00e4hrend zugleich geschichtspolitische Eingriffe in Kulturerbeeinrichtungen kontrovers diskutiert werden.
\n2026 findet die dritte Ausgabe des gro\u00dfen OER-Fachtags von ORCA.nrw statt. Freuen Sie sich \u00fcber den Tag hinweg auf eine spannende Keynote, Projektvorstellungen, Workshops und viel Austausch & Vernetzung!
\nIm Vortrag wird, ankn\u00fcpfend an das Blockchain-Projekt f\u00fcr digitale Zeugnisse, die EUDI-Wallet thematisiert. Die Historie der Entwicklung dieser digitalen Brieftasche auf EU-Ebene wird vorgestellt und die Funktionen und M\u00f6glichkeiten sowie Detailinformationen zur Sicherheit werden erl\u00e4utert. Der aktuelle Stand der Entwicklung wird betrachtet und in Form einer Demo wird die Nutzung an einem konkreten Beispiel veranschaulicht. Nach einem Blick auf zuk\u00fcnftige Entwicklungen im Bereich \"Digitaler Identit\u00e4ten\", wie z. B. Post-Quanten-Verschl\u00fcsselung oder Alternative Biometrische Identifikationsverfahren (AuBi) schlie\u00dft der Abend mit Raum f\u00fcr Diskussionen \u00fcber die Technologie und deren Nutzung.
\nDer Einsatz von KI Technologien erstreckt sich zunehmend auf zentrale Bereiche politischer Steuerung, von der \u00f6ffentlichen Verwaltung und der Umweltpolitik bis hin zu Grenzregimen und wirtschaftlicher Regulierung. Dabei ver\u00e4ndern sie nicht nur Verfahren; es verschieben sich Machtkonstellationen, Verantwortung und politische Handlungsspielr\u00e4ume. Das Symposium mit \u00f6ffentlicher Paneldiskussion diskutiert KI als systemische Herausforderung f\u00fcr Demokratie und Rechtsstaat. Die Veranstaltung bietet kurze Einf\u00fchrungen in verschiedene Schwerpunkte unserer Forschung und erm\u00f6glicht eine kollaborative Plattform zur Diskussion der systemischen Kosten algorithmischer Governance f\u00fcr demokratische Strukturen. Dies schafft einen offenen Raum f\u00fcr Austausch mit politischen Entscheidungstr\u00e4ger*innen, Vertreter*innen von NGOs, Forschenden sowie allen, die an der Zukunft einer digitalen Gesellschaft interessiert sind.
\nDas Digitale ist ein gro\u00dfes Versprechen: Physische R\u00e4ume und pers\u00f6nliche Speichermedien scheinen ganz \u00fcberfl\u00fcssig zu werden, die Cloud soll ortsunabh\u00e4ngigen, schnellen Zugriff und unbegrenzten Speicherplatz erm\u00f6glichen. Aber was kostet das, welche L\u00f6sungen sind sicher und umweltvertr\u00e4glich?\u00a0Gemeinsam mit bestandserhaltenden Einrichtungen und Vertreter:innen aus Wissenschaft und Forschung wollen wir das Versprechen des Digitalen \u00fcberpr\u00fcfen und konstruktive Vorschl\u00e4ge zur longue dur\u00e9e des digitalen Erbes entwickeln. Es sprechen u.v. a.: Frank Scholze (Deutsche Nationalbibliothek), Richard Ovenden (Bodleian Library Oxford) und Petra Gehring (Rat f\u00fcr Informationsinfrastrukturen).
\nDas Open Science Forum Mitteldeutschland 2026 bringt am 5. Oktober Interessierte zu einem offenen Austausch \u00fcber Open Science als Gestaltungsaufgabe zusammen. Wir widmen uns der Frage, welche Rolle wissenschaftsunterst\u00fctzende Einrichtungen spielen, wenn es um neue Ans\u00e4tze in der Forschungsbewertung, nachhaltige Infrastrukturen und digitale Souver\u00e4nit\u00e4t im Spannungsfeld geopolitischer Entwicklungen geht.
\nIn Archiven, Bibliotheken und anderen Ged\u00e4chtniseinrichtungen lagern bundesweit gef\u00e4hrdete Originale, die Meinungsvielfalt, Rechtsordnungen, historische Entwicklungen und politisches Handeln dokumentieren. Der Erhalt dieser \u00dcberlieferungen ist Grundvoraussetzung f\u00fcr eine quellen- und faktenbasierte Forschung, eine historische Aufarbeitung sowie die Sichtbarmachung gesellschaftlicher Mehrstimmigkeit und Diskurse. Originalerhalt ist grundlegender Bestandteil der Informationssicherung und ein wichtiger Beitrag zu einer lebendigen, urteilsf\u00e4higen und wehrhaften Demokratie \u2013 insbesondere angesichts der zunehmenden Bedrohung durch hybride Desinformation und andere demokratiegef\u00e4hrdende Entwicklungen.
\nDie FDM-Sprechstunde Humanities@NFDI ist eine Online-Beratung f\u00fcr Studierende, Forschende oder Mitarbeitende aus Forschungs- und Sammlungsinstitutionen zu allen Fragen rund um das Forschungsdatenmanagement. Expert:innen aus den geisteswissenschaftlichen NFDI-Konsortien NFDI4Memory, NFDI4Culture, NFDI4Objects und Text+ stehen f\u00fcr Ihre Fragen zu allen Themen rund ums Forschungsdatenmanagement bereit. Bei Bedarf k\u00f6nnen Einzelgespr\u00e4che in Breakoutr\u00e4umen vertieft werden.
\nIncreasing consolidation and commercial control over all aspects of knowledge comes at a cost. This year's theme challenges us to consider the financial, human, and environmental costs of creating, sharing, and sustaining knowledge\u2014particularly when these costs are driven by private rather than public interests. Last year's theme of \"Who owns our knowledge?\" reflected on the reality of commercial ownership of knowledge. This year's theme will reckon with the costs of that reality and avenues for reclaiming control of these systems meant to serve the public interest.
\nDer Aktionstag \"Forschungsdaten@BUA\" l\u00e4dt erstmals Forschende der Berlin University Alliance herzlich ein, \u00fcber den Umgang mit Forschungsdaten ins Gespr\u00e4ch zu kommen, sich auszutauschen und zu vernetzen. Ziel ist es, Best Practices sichtbar zu machen, Erfahrungen auszutauschen und den Dialog \u00fcber den Umgang mit Forschungsdaten \u00fcber die vier BUA-H\u00e4user hinweg auszubauen.
\nIn diesem Workshop lernen die Teilnehmenden datenschutzkonforme KI-Anwendungen und Einsatzm\u00f6glichkeiten kennen, die neue Wege f\u00fcr die Nachnutzung von Forschungsdaten erm\u00f6glichen und zur Verbesserung von Datenqualit\u00e4t, Metadatenverf\u00fcgbarkeit und Zug\u00e4nglichkeit beitragen. Mithilfe konkreter Anwendungsf\u00e4lle aus der Forschung werden die rechtssicheren Einsatzm\u00f6glichkeiten der KI im Datenlebenzyklus vorgestellt.
\nDer Workshop f\u00fchrt in die Grundfunktionen von OpenRefine ein und zeigt an konkreten Anwendungsf\u00e4llen, wie Forschende tabellarische Datens\u00e4tze bereinigen, strukturieren und anreichern k\u00f6nnen. Dabei werden auch geskriptete Bearbeitungsschritte sowie der Import und Export verschiedener Datenformate (CSV, XML, JSON) behandelt. OpenRefine erm\u00f6glicht nicht nur einen schnellen \u00dcberblick \u00fcber gro\u00dfe Datens\u00e4tze, sondern hilft vor allem bei heterogenen und historisch gewachsenen Datens\u00e4tze, die oft inkonsistente Metadaten aufweisen.
\nDer Workshop gibt einen \u00dcberblick \u00fcber ELN-Konzepte, zeigt relevante Forschungsdatenmanagement-Aspekte auf und bietet eine praktische Einf\u00fchrung.
\nIm Rahmen dieses Hands-on-Workshops werden Konzepte zum effizienten, reproduzierbaren und nachvollziehbaren Arbeiten mit Forschungsdaten vermittelt. Ziel ist es, die Teilnehmenden mit verschiedenen Werkzeugen vertraut zu machen und das Bewusstsein f\u00fcr Computational Thinking, Automatisierung sowie die Optimierung eigener Arbeitsprozesse zu sch\u00e4rfen.
\nIm Forschungsalltag stehen Forschende regelm\u00e4\u00dfig vor urheberrechtlichen Fragen: Welche Inhalte darf ich in meiner Arbeit verwenden? Unter welchen Bedingungen kann ich Daten und Materialien offen teilen? Wie gehe ich mit KI-Tools und deren Trainingsdaten rechtssicher um? Dieser Workshop bietet praxisnahe Orientierung f\u00fcr den sicheren Umgang mit gesch\u00fctzten Inhalten und Lizenzen in der wissenschaftlichen Arbeit.
\nIn our three-part workshop series, we explore the relationship between the technical aspects, practical applications and critical reflection of the use of AI in research data management. Participants will learn about various AI tools and use cases for research data management, test, and develop criteria for the meaningful and responsible use of AI in their own work.
