Many foresight studies concentrate on technological foresight and its impact at the organizational level. However, often these studies overlook the soft factor of employee competences which is critical to adopting technological and organizational changes and to developing the necessary innovation capabilities. This study investigates the theoretical and methodological underdeveloped relationship between technological innovation and social initiated change and the impact on individual competences in a dynamic sector. The setting of our study is the turbulent creative industries as a whole, where creative and artistic expression merges with changing technological progress. In a scenario study we mainly conducted in 2010, we developed a scenario model for competences to combine individual competences with a scenario approach to investigate how competences are important to the sector shift or need to be enhanced in the future. We use primary qualitative data from expert interviews and workshops and secondary data from industry reports to identify thirty-seven influence factors. An influence matrix calculation and a cluster analysis are used to project three different scenarios presenting how future developments of the creative industries will influence the competences needed for creative occupations. Now, five years later, we reflect the accuracy of the developed scenarios via a comparison of today's situation with the situation in the scenarios. We discuss theoretical contributions for the foresight literature and practical implementations for the future of work in general, and in particular for the creative industries case.

Ordinary differential equations (ODEs) have been studied for centuries as a means to model complex dynamical processes from the real world. Nevertheless, their application to sound synthesis has not yet been fully exploited. In this article we present a systematic approach to sound synthesis based on first-order complex and real ODEs. Using simple time-dependent and nonlinear terms, we illustrate the mapping between ODE coefficients and physically meaningful control parameters such as pitch, pitch bend, decay rate, and attack time. We reveal the connection between nonlinear coupling terms and frequency modulation, and we discuss the implications of this scheme in connection with nonlinear synthesis. The ability to excite a first-order complex ODE with an external input signal is also examined; stochastic or impulsive signals that are physically or synthetically produced can be presented as input to the system, offering additional synthesis possibilities, such as those found in excitation/filter synthesis and filter-based modal synthesis.
Das Rahmenkonzept der Universitätsschule Potsdam beschreibt die Wertegrundlage und das pädagogisch-didaktische sowie das wissenschaftliche Fundament einer zu gründenden Universitätsschule Potsdam. Wie andere Universitätsschulen soll sich auch diese Schule durch eine enge und institutionalisierte Beziehung zwischen Schule und Universität auszeichnen, die den ständigen Wissenstransfer zwischen Schulpraxis, Wissenschaft, Lehrkräftebildung und Schulverwaltung unterstützt. Das Rahmenkonzept legt die Grundlagen für eine inklusive Schule, deren Schüler:innen einen Querschnitt der Gesellschaft abbilden, und die in ungleichheitssensiblen Bildungsangeboten alle Bildungsabschlüsse des Landes Brandenburg anbietet. Die Universitätsschule soll den starken Segregationsprozessen in Potsdam entgegenwirken.
Im Leitbild werden die Grundwerte (Nachhaltigkeit, Inklusion und Bildungsgerechtigkeit, Menschenrechte und Demokratie, Gemeinschaft, Ganzheitlichkeit) und die Bildungsziele (Transferfähigkeit, kritisch-reflexives Denken und lebensbegleitendes Lernen, Diversitätsbewusstsein und Transkulturalität, Selbstkompetenz und Beziehungskompetenz, Kulturtechniken und digitale Kompetenz) der Universitätsschule dargestellt. Das Pädagogische Konzept veranschaulicht, wie Werte und Bildungsziele in den Bereichen Schulform, Schulkultur, Lernkultur sowie Lernorte und Lernumgebung ausgestaltet werden können. Schließlich wird die Universitätsschule als lernende und lehrende Institution beschrieben, die ein Ort des Transfers von Bildungsinnovationen ist. Dafür soll eine Transferwerkstatt in der Schule verankert werden, die den Wissensaustausch der schulrelevanten Akteur:innen unterstützt und gestaltet.
We present a general approach to planning with incomplete information in Answer Set Programming (ASP). More precisely, we consider the problems of conformant and conditional planning with sensing actions and assumptions. We represent planning problems using a simple formalism where logic programs describe the transition function between states, the initial states and the goal states. For solving planning problems, we use Quantified Answer Set Programming (QASP), an extension of ASP with existential and universal quantifiers over atoms that is analogous to Quantified Boolean Formulas (QBFs). We define the language of quantified logic programs and use it to represent the solutions different variants of conformant and conditional planning. On the practical side, we present a translation-based QASP solver that converts quantified logic programs into QBFs and then executes a QBF solver, and we evaluate experimentally the approach on conformant and conditional planning benchmarks.
Vorliegender Leitfaden ist eines der Ergebnisse des Forschungsprojekts „Open Innovation in Life Sciences“ (OIL), das von Mai 2008 bis April 2011 an der Universität Potsdam durchgeführt wurde. Er nimmt für sich in Anspruch, gerade Innovationsmanager in kleinen und mittleren Unternehmen (KMU) der Pharmaindustrie bei der Einführung des Open Innovation Managements zu unterstützen. Zielsetzung des Forschungsprojekts war es, (1) die Chancen und Risiken von Open Innovation unter besonderer Berücksichtigung der Anforderungen von Pharma-KMU zu analysieren und (2) daraus abgeleitet ein Konzept zur Implementierung von Open Innovation bei Pharma-KMU zu entwickeln. Der Ausgangspunkt des Projektes war die Erkenntnis, dass die Life Sciences-Branche im Allgemeinen und die Pharmaindustrie im Besonderen durch eine steigende Komplexität der Innovationsprozesse und eine zunehmende Tendenz zu Kooperationen gekennzeichnet ist. Vor diesem Hintergrund eröffnet gerade der Open Innovation-Ansatz für die Pharmabranche neue Gestaltungs- und damit Wachstumsmöglichkeiten. Open Innovation – definiert als die planvolle Öffnung der Innovationsprozesse und die strategische Einbindung des Unternehmensumfelds – wird dabei als zentraler Erfolgsfaktor für die Innovationsfähigkeit beschrieben.
MALDI-TOF-MS-based identification of monoclonal murine Anti-SARS-CoV-2 antibodies within one hour
(2022)
During the SARS-CoV-2 pandemic, many virus-binding monoclonal antibodies have been developed for clinical and diagnostic purposes. This underlines the importance of antibodies as universal bioanalytical reagents. However, little attention is given to the reproducibility crisis that scientific studies are still facing to date. In a recent study, not even half of all research antibodies mentioned in publications could be identified at all. This should spark more efforts in the search for practical solutions for the traceability of antibodies. For this purpose, we used 35 monoclonal antibodies against SARS-CoV-2 to demonstrate how sequence-independent antibody identification can be achieved by simple means applied to the protein. First, we examined the intact and light chain masses of the antibodies relative to the reference material NIST-mAb 8671. Already half of the antibodies could be identified based solely on these two parameters. In addition, we developed two complementary peptide mass fingerprinting methods with MALDI-TOF-MS that can be performed in 60 min and had a combined sequence coverage of over 80%. One method is based on the partial acidic hydrolysis of the protein by 5 mM of sulfuric acid at 99 degrees C. Furthermore, we established a fast way for a tryptic digest without an alkylation step. We were able to show that the distinction of clones is possible simply by a brief visual comparison of the mass spectra. In this work, two clones originating from the same immunization gave the same fingerprints. Later, a hybridoma sequencing confirmed the sequence identity of these sister clones. In order to automate the spectral comparison for larger libraries of antibodies, we developed the online software ABID 2.0. This open-source software determines the number of matching peptides in the fingerprint spectra. We propose that publications and other documents critically relying on monoclonal antibodies with unknown amino acid sequences should include at least one antibody fingerprint. By fingerprinting an antibody in question, its identity can be confirmed by comparison with a library spectrum at any time and context.
At present, several virtual initiatives claim to be acting according to the open source software (OSS) arena, which is often deemed a role model for open innovation. Against this background, this research focuses on a comparative case study of two non-profit project networks that attempt to operate in line with the OSS phenomenon: Wikipedia, the online encyclopedia, and the development of an automobile, Open Source car. We show that many parallels to the OSS arena can be drawn in both cases. However, this analysis must be performed cautiously, as several factors limit the applicability of OSS principles to non-software-related arenas. We conclude with a discussion of implications for open innovation research and managerial practice.
Unlike for other retroviruses, only a few host cell factors that aid the replication of foamy viruses (FVs) via interaction with viral structural components are known. Using a yeast-two-hybrid (Y2H) screen with prototype FV (PFV) Gag protein as bait we identified human polo-like kinase 2 (hPLK2), a member of cell cycle regulatory kinases, as a new interactor of PFV capsids. Further Y2H studies confirmed interaction of PFV Gag with several PLKs of both human and rat origin. A consensus Ser-Thr/Ser-Pro (S-T/S-P) motif in Gag, which is conserved among primate FVs and phosphorylated in PFV virions, was essential for recognition by PLKs. In the case of rat PLK2, functional kinase and polo-box domains were required for interaction with PFV Gag. Fluorescently-tagged PFV Gag, through its chromatin tethering function, selectively relocalized ectopically expressed eGFP-tagged PLK proteins to mitotic chromosomes in a Gag STP motif-dependent manner, confirming a specific and dominant nature of the Gag-PLK interaction in mammalian cells. The functional relevance of the Gag-PLK interaction was examined in the context of replication-competent FVs and single-round PFV vectors. Although STP motif mutated viruses displayed wild type (wt) particle release, RNA packaging and intra-particle reverse transcription, their replication capacity was decreased 3-fold in single-cycle infections, and up to 20-fold in spreading infections over an extended time period. Strikingly similar defects were observed when cells infected with single-round wt Gag PFV vectors were treated with a pan PLK inhibitor. Analysis of entry kinetics of the mutant viruses indicated a post-fusion defect resulting in delayed and reduced integration, which was accompanied with an enhanced preference to integrate into heterochromatin. We conclude that interaction between PFV Gag and cellular PLK proteins is important for early replication steps of PFV within host cells.
