    Designing an information architecture for data management technologies: Introducing the DIAMANT model

    Full text link
    Although research institutions take on increased responsibility for providing infrastructures and services around the proper handling of research data, there is no comprehensive framework addressing the ideal conditions of this implementation process. To overcome this gap, we present the DIAMANT model, a reference model aimed at providing an orientation framework for the implementation of research data management guided by the research process itself. It builds upon a central research data management information unit controlling the information flow between all other organizational units involved in research data management. Due to the possibility of outsourcing organizational units, the implementation process is maximally flexible and efficient

    Die Nachbehandlung von Beton mit flüssigen (chemischen) Nachbehandlungsmitteln stellt in vielen Fällen eine Alternative zu klassischen Nachbehandlungsarten,wie das Abdecken mit Folie oder das Auflegen von wasserspeichernden Abdeckungen,dar. Hierzu kommen Nachbehandlungsmittel unterschiedlicher chemi-scher Zusammensetzung zum Einsatz, die alle nach dem Auftrageneinen Film bilden, der die Wasserabgabe des Betons reduziert. Je nach Anwendungsgebiet werden unterschiedliche Nachbehandlungsmittel einge-setzt; im Betonstraßenbau sind Nachbehandlungsmittel auf der Basis von Paraffinwachsemulsionenam ver-breitetsten,wogegen bei Estrichen und Industrieböden häufiger Polymerdispersionen eingesetzt werden. Bei allen Nachbehandlungsmitteln ist die richtige Applikationentscheidendfür eine wirksame Nachbehandlung, insbesondere deroptimaleAuftragszeitpunkt spielt dabei eineentscheidende Rolle. Dieser Artikel erläutert die verschiedenen Arten von Nachbehandlungsmitteln, ihre Wirkungsweise sowie Einflüsse auf diese

    The 3-dimensional Fourier grid Hamiltonian method

    Get PDF
    A method to compute the bound state eigenvalues and eigenfunctions of a Schr\"{o}dinger equation or a spinless Salpeter equation with central interaction is presented. This method is the generalization to the three-dimensional case of the Fourier grid Hamiltonian method for one-dimensional Schr\"{o}dinger equation. It requires only the evaluation of the potential at equally spaced grid points and yields the radial part of the eigenfunctions at the same grid points. It can be easily extended to the case of coupled channel equations and to the case of non-local interactions.Comment: 13 pages, 1 figure. RevTeX file. To appear in J. Comput. Phy

    Light during darkness and cancer: relationships in circadian photoreception and tumor biology

    Get PDF
    The relationship between circadian phototransduction and circadian-regulated processes is poorly understood. Melatonin, commonly a circadian phase marker, may play a direct role in a myriad of physiologic processes. The circadian rhythm for pineal melatonin secretion is regulated by the hypothalamic suprachiasmatic nucleus (SCN). Its neural source of light input is a unique subset of intrinsically photosensitive retinal ganglion cells expressing melanopsin, the primary circadian photopigment in rodents and primates. Action spectra of melatonin suppression by light have shown that light in the 446–477 nm range, distinct from the visual system’s peak sensitivity, is optimal for stimulating the human circadian system. Breast cancer is the oncological disease entity whose relationship to circadian rhythm fluctuations has perhaps been most extensively studied. Empirical data has increasingly supported the hypothesis that higher risk of breast cancer in industrialized countries is partly due to increased exposure to light at night. Studies of tumor biology implicate melatonin as a potential mediator of this effect. Yet, causality between lifestyle factors and circadian tumor biology remains elusive and likely reflects significant variability with physiologic context. Continued rigorous empirical inquiry into the physiology and clinical implications of these habitual, integrated aspects of life is highly warranted at this time

    PsyCuraDat: Developing curation criteria and standards enabling the sustainable (re)use of psychological research data. In the course of the open science movement, sharing research data in order to increase the sustainable (re-)use of the data has increasingly become commonplace. The PsyCuraDat project was created to support psychologists in documenting their research data in a sustainable way by developing discipline-specific curation criteria and standards for psychological research data. The project’s work began by investigating existing curation criteria and standards, assessing their reuse potential and querying the nature of necessary information and requirements for the sustainable (re-)use of research data in psychology. Further research, including expert interviews and several user studies with researchers in psychology, lead to the development of prototype versions of a documentation standard which were then tested and evaluated for their usability. As the project’s outcome, a data documentation standard called D-Psy-FAIR was finally developed enabling the comprehensible linkage between information on the project, design, measurement and data of a given study. Specifically, D-Psy-FAIR comprises four documentation steps including the creation of a study-description (step 1), the creation of an extended codebook (step 2), the documentation of data preparation and analysis scripts (step 3), as well as the creation of a graphical overview of the research data process (step 4). Following the D-Psy-FAIR documentation approach, which is imparted through learning materials and tutorials developed within the project, leads to the creation of (re-)usable and thus sustainable data. Further, the D-Psy-FAIR standard’s establishment in relevant infrastructures (e.g. the data documentation tool DataWiz) improves their interoperability that serves the purpose of data archiving as well as data sharing. In this poster, we would like to introduce D-Psy-FAIR and present our approach to sustainable data documentation in psychology

    Dynamically generated open charmed baryons beyond the zero range approximation

    Get PDF
    The interaction of the low lying pseudo-scalar mesons with the ground state baryons in the charm sector is studied within a coupled channel approach using a t-channel vector-exchange driving force. The amplitudes describing the scattering of the pseudo-scalar mesons off the ground-state baryons are obtained by solving the Lippmann--Schwinger equation. We analyze in detail the effects of going beyond the t=0t=0 approximation. Our model predicts the dynamical generation of several open charmed baryon resonances in different isospin and strangeness channels, some of which can be clearly identified with recently observed states.Comment: 7 figures, 8 table

    Streamlining Research Data Management – The Research Perspective of the PODMAN Project

    Get PDF
    Ausgehend von der Notwendigkeit, die Integration von Forschungsdatenmanagement in bestehende Forschungsprozesse zu optimieren, stellt dieser Beitrag das BMBF-Projekt PODMAN vor. Es kombiniert Konzepte des Prozessmanagements und der Psychologie zu einem prototypischen Forschungsdatenmanagement-Modell. Hierbei bezieht es Forscher aus den Geisteswissenschaften und der Psychologie sowie die Infrastruktureinrichtungen an der Universität Trier und dem Zentrum für Psychologische Information und Dokumentation (ZPID) mit ein.Facing the challenge of streamlining the integration of research and research data management, this paper presents the PODMAN project. PODMAN combines process management and psychological concepts to develop a prototypical model. Therefore, it considers the perspective of researchers from the humanities and psychology. It also integrates the infrastructural perspective at the University of Trier and the Leibniz Institute for Psychology Information
