Participation of New Editors After Times of Shock on Wikipedia

User participation is vital to the success of collaborative crowdsourcing platforms such as Wikipedia. Previously user participation has been studied during “normal times”. However, less is known about participation following shocks that draw attention to an article. Such events can be recruiting opportunities due to increased attention; but can also pose a threat to the quality and control of the article and drive away newcomers. We study the collaborative dynamics of Wikipedia articles after times corresponding to shocks generated by drastic increases in attention as indicated by data from Google trends.We find that participation following such events is indeed different from participation during normal times–both newcomers and incumbents participate at higher rates during shocks. We also identify collaboration dynamics that mediate the effects of shocks on continued participation after the shock. The impact of shocks on participation is mediated by the amount of negative feedback given to newcomers in the form of reverted edits and the amount of coordination editors engage in through edits of the article’s talk page.National Science Foundation Grant No. IIS-1617820Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/148429/1/Zhang et al. 2019.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/148429/4/3253-Article Text-6302-1-10-20190531.pdfDescription of Zhang et al. 2019.pdf : Preprint versionDescription of 3253-Article Text-6302-1-10-20190531.pdf : Final Versio

Neuromatch Academy: Teaching Computational Neuroscience with global accessibility

Neuromatch Academy designed and ran a fully online 3-week Computational Neuroscience summer school for 1757 students with 191 teaching assistants working in virtual inverted (or flipped) classrooms and on small group projects. Fourteen languages, active community management, and low cost allowed for an unprecedented level of inclusivity and universal accessibility.Comment: 10 pages, 3 figures.

Neuromatch Academy: a 3-week, online summer school in computational neuroscience

Neuromatch Academy (https://academy.neuromatch.io; (van Viegen et al., 2021)) was designed as an online summer school to cover the basics of computational neuroscience in three weeks. The materials cover dominant and emerging computational neuroscience tools, how they complement one another, and specifically focus on how they can help us to better understand how the brain functions. An original component of the materials is its focus on modeling choices, i.e. how do we choose the right approach, how do we build models, and how can we evaluate models to determine if they provide real (meaningful) insight. This meta-modeling component of the instructional materials asks what questions can be answered by different techniques, and how to apply them meaningfully to get insight about brain function

Mundstück mit einem Kanal

Die Erfindung bezieht sich auf ein Mundstück (1, 1') zum Einsatz in den Mund eines Probanden mit einem an wenigstens einer Außenseite des Mundstücks in einer ersten Öffnung (20) mündenden Kanal (19, 41) zur Förderung einer Flüssigkeit, wobei in oder an dem Kanal (19, 41) oder in einem mit dem Kanal in Verbindung stehenden Hohlraum ein oder mehrere Sensoren (22, 22') zur Erfassung wenigstens einer Messgröße der Flüssigkeit angeordnet ist und wobei das Mundstück wenigstens teilweise elastisch verformbar ist, durch eine elastische Verformung des Mundstücks wenigstens bereichsweise eine Verformung des Kanals (19, 41) erfolgt und durch die Verformung des Kanals eine Pumpwirkung entlang dem Kanal erzeugt wird

Rapid detection of human anti-HCV immunoglobulins on electrical biochips

The detection of hepatitis C virus (HCV) in the blood of patients is currently based on immunological assays (enzyme-linked immunosorbent assay [ELISA] and recombinant immunoblot assay) that use different HCV epitopes to detect anti-HCV antibodies, and these tests usually require laboratories and trained personnel. The ELISA-based systems are also time consuming. Portable diagnostic devices offering rapid test results would therefore be advantageous in the field of medical care. To facilitate the fast and reliable diagnosis of HCV, we used a miniaturized automated system based on a cartridge with an integrated electrical biochip for the decentralized detection of anti-HCV antibodies against the Core, NS3, and NS4A proteins. This system allows the detection of virus-specific antibodies in 2 µL of serum or whole blood within 15 minutes using an ELISA directly on a gold electrode array containing HCV proteins as the capture antigen. The sensitivity of this system is comparable with standard microtiter plate ELISAs, but the duration of the novel assay is 5%–6% that of standard ELISAs
