  text: Modern industrial development has necessitated a wide range of joining technologies.
    Self-pierce riveting has become a prevalent technique for sheet metal assembly,
    especially in automotive applications. Achieving proper joint geometry and adequate
    load-bearing capacity depends on appropriate tool selection and precise process
    control. Material properties and condition also play a significant role in process
    performance. To accommodate the inevitable variations in component characteristics
    during production, a robust and stable joining process is essential. The study
    focuses on investigating the influence of preformed joining partners on the joining
    process and the joint's load capacity. An EN AW-6014 in T4 condition, as well
    as an HCT590X, are used as materials for this study. For this purpose, an exemplary
    process chain consisting of the steps of performing, joining, and shear load testing
    is studied. Each process step is implemented using an FE model to predict the
    outcome of subsequent steps. For analysis of the influence of pre-strain, an optimisation
    software is used to plan and execute variations of the process. These variations
    are used to create a meta-model that can describe the relationships between pre-forming
    and characteristic parameters of subsequent process steps. The resulting model
    is validated by comparing simulation and experimental data. Finally, in a novel
    approach, the robustness of the presented process chain is analyzed in terms of
    a tolerable performance level for the joining partners.

  text: 'Twitter ist jetzt X und befindet sich auf dem absteigenden Ast. Auf diesem
    Ast sitzt Facebook bereits seit längerem. Der Kurzvideodienst Vine, Vorgänger
    von TikTok, ist Geschichte. Und auch bei Google klingeln die Alarmglocken angesichts
    der „neuen“ Konkurrenz durch Microsoft und ChatGPT. Umso dringlicher wird also
    die Historisierung der „sozialen Medien“, das heißt, sie in ihren historischen
    Kontext einzuordnen und ihren Mythos zu entzaubern. Dabei wartet das Vorhaben
    mit einer doppelten Herausforderung auf: Erstens, dass es sich bei den Unternehmen
    der Branche und zweitens auch bei den dort gebildeten Gemeinschaften um recht
    flüchtige, wandelhaften Gestalten handelt. Scheitern und Wandel ist Teil der „sozialen
    Medien“ – und sei es nur in der schnellen Abfolge der Moden des „nächsten großen
    Dings“. Dementsprechend versucht dieser Beitrag mit einem systematischeren Ansatz
    als dem der gesellschaftlichen Selbstbeschreibung, die Entwicklung des sozio-digitalen
    Phänomens „soziale Medien“ in dessen Zeitkontext einzuordnen.'

  text: Within innovation management, choosing the best fitting product idea is the
    most important decision point. The future existence and success of the organization
    is depending on selected product ideas. To find the best fitting idea for an organization,
    it needs evaluation criteria representing the organizations mission Therefore,
    this study focuses on a holistic overview about evaluation criteria and on supporting
    organizations in the process to select its individual evaluation criteria. Based
    on a literature study, existing approaches regarding evaluation criteria in product
    idea selection are identified and a list of evaluation criteria is reworked. Using
    the list of evaluation criteria, a prioritization method is created. Within an
    interview with experts in innovation management, the method is discussed regarding
    usability and the level of assistance in product idea selection. The developed
    criteria can be used directly by innovation manager and industrial practitioners
    to evaluate potential product ideas.

  text: "In innovation management, usually there is a large number of product ideas,
    not all of which meet the requirements of a company and make sense to pursue further.
    For selecting the most promising ideas, several methods exist which each focus
    on a certain aspect. Due to the characteristics of Small and Medium Enterprises
    (SMEs) such as limited resources, these enterprises have special requirements
    on methods for selecting ideas. In this study, criteria of SMEs for idea selection
    are deducted from SME-characteristics. Methods for idea selection are tested for
    fulfillment of these criteria and the results are combined in a matrix. Together
    with a guideline, a tool for idea selection in innovation management of SMEs is
    developed. The results are validated in the context of innovation management in
    SMEs. By selecting a method, a SME is enabled to make economically viable decisions
    for their product portfolio, thus\r\nensuring sustainable economic success."

  text: The economic relevance of information systems has been studied for many years
    and has attracted an abundance of research papers. However, the ?productivity
    paradoxon? of the 90s, Carr?s widely recognized paper ?IT doesn?t matter?, and
    several studies that do not find a positive correlation between IS investments
    and economic performance reveal long-lasting difficulties for IS researchers to
    explain ?IS business value?. Business executives and researchers also continue
    to question the value of IS investments. This raises the question of whether literature
    reviews have tapped their potential to address the concerns by covering key research
    areas of IS business value and preserving their key findings. In order to address
    this question, this paper identifies and describes 12 key research areas, and
    synthesizes what literature reviews published in pertinent academic outlets have
    done to preserve knowledge. The analysis of 22 literature reviews shows that some
    crucial areas have not been (sufficiently) covered. They provide fertile areas
    for future literature reviews. As this work is based on the results of more than
    200 research papers, it is capable of drawing a comprehensive picture of the current
    state-of-the-art in IS business value research.
