  text: We investigate differences in bribing decisions among two generations from
    East and West Germany in a bribery game conducted as an online study (N=168).
    This way, we aim to explore moral considerations of individuals influenced by
    two formerly different institutional systems. We find a higher propensity to bribe
    among young Germans compared to the older generation. Young East Germans even
    reveal a slightly greater inclination to bribe than their West German counterparts.
    We conclude that preferences for personal favors may be induced among young East
    Germans given the tense relationship between market opportunities and conveyed
    cultural traits of a socialist imprint.

  text: Die Studienlage zum Thema Bewegung, Spiel und Sport im schulischen Ganztag
    in Deutschland zeigt sich vielseitig. Das Forschungsfeld ist neben wenigen umfassenden,
    überregionalen Studien durch kleinere Studien mit spezifischen inhaltlichen Schwerpunkten
    gekennzeichnet. Das vorliegende Scoping Review zielt darauf ab, die Erkenntnisse
    des Forschungsfeldes der circa vergangenen 20 Jahre zu systematisieren. Leitend
    ist die Forschungsfrage „Wie stellt sich der aktuelle Forschungsstand im Feld
    von Bewegung, Spiel und Sport im schulischen Ganztag in Deutschland dar?“ Auf
    Basis einer systematischen Literaturrecherche in fünf Datenbanken konnten aus
    2365 Publikationen 52 in die Analyse eingeschlossen werden. Überwiegend wurden
    regionale Querschnittsstudien mit spezifischem Fokus durchgeführt. Die Studien
    befassen sich zumeist mit den Rahmenbedingungen von Bewegung, Spiel und Sport
    im Ganztag sowie mit den Charakteristika von Bewegung, Spiel und Sport im Ganztag.
    Die Analyse verdeutlicht unter anderem den Mangel an längsschnittlichen Studien
    sowie den Forschungsbedarf im Bereich der Qualität von Bewegung in diesem Setting.

  text: In this paper we consider the interactive processes by which an explainer
    and an explainee cooperate to produce an explanation, which we refer to as co-construction.
    Explainable Artificial Intelligence (XAI) is concerned with the development of
    intelligent systems and robots that can explain and justify their actions, decisions,
    recommendations, and so on. However, the cooperative construction of explanations
    remains a key but under-explored issue. This short paper proposes an architecture
    for intelligent systems that promotes a co-constructive and interactive approach
    to explanation generation. By outlining its basic components and their specific
    roles, we aim to contribute to the advancement of XAI computational frameworks
    that actively engage users in the explanation process.

  text: Compounding is an important step in processing base polymers and is used to
    incorporate various additives into a polymer. For this purpose, different screw
    elements are used for dispersive and distributive mixing on a co-rotating twin-screw
    extruder. Optimising the screw configuration requires precise knowledge of the
    screw elements’ mixing properties, which have not been thoroughly investigated.
    This study analyses the mixing behaviour of individual screw elements regarding
    dispersive and distributive mixing using 3D CFD flow simulations with subsequent
    particle tracking. For distributive mixing, the particle distribution behind the
    screw elements in the XY plane is analysed and the mixing index MQ, which relates
    the standard deviation and the mean value of the triangular areas between the
    particles, is calculated. For dispersive mixing, the maximum shear stress on the
    particle path and the integral of the shear stress over the residence time of
    each individual particle are determined. The results show that screw element geometry
    and rotation speed have a significant influence on dispersive and distributive
    mixing. In addition, better dispersive mixing is achievable with highly viscous
    materials. These findings enable the optimisation of the mixing zone of a co-rotating
    twin-screw extruder for the efficient mixing of mineral fillers.

  text: Most single-screw extruders used in the plastics processing industry are plasticizing
    extruders, designed to melt solid pellets or powders within the screw channel
    during processing. In many cases, the efficiency of the melting process acts as
    the primary throughput-limiting factor. If the material melts too late in the
    process, it may not be sufficiently mixed, resulting in substandard product quality.
    Accurate prediction of the melting process is therefore essential for efficient
    and cost-effective machine design. A practical method for engineers is the modeling
    of the melting process using mathematical–physical models that can be solved without
    complex numerical methods. These models enable rapid calculations while still
    providing sufficient predictive accuracy. This study revisits the modified Tadmor
    model by Potente, which describes the melting process and predicts the delay-zone
    length, extending from the hopper front edge to the point of melt pool formation.
    Based on extensive experimental investigations, this model is adapted by redefining
    the flow temperatures at the phase boundary and accounting for surface porosity
    at the beginning of the melting zone. Additionally, the effect of variable solid
    bed dynamics on model accuracy is examined. Significant model improvements were
    achieved by accounting for reduced heat flow into the solid bed due to the porous
    surface structure in the solid conveying zone, along with a new assumption for
    the flow temperature at the phase boundary between the solid bed and melt film.

  text: Ferroelectric materials play a crucial role in a broad range of technologies
    due to their unique properties that are deeply connected to the pattern and behavior
    of their ferroelectric (FE) domains. Chief among them, barium titanate (BaTiO3;
    BTO) sees widespread applications such as in electronics but equally is a ferroelectric
    model system for fundamental research, e.g., to study the interplay of such FE
    domains, the domain walls (DWs), and their macroscopic properties, owed to BTO’s
    multiple and experimentally accessible phase transitions. Here, we employ Second
    Harmonic Generation Microscopy (SHGM) to in situ investigate the cubic-to-tetragonal
    (at ∼126°C) and the tetragonal-to-orthorhombic (at ∼5°C) phase transition in single-crystalline
    BTO via three-dimensional (3D) DW mapping. We demonstrate that SHGM imaging provides
    the direct visualization of FE domain switching as well as the domain dynamics
    in 3D, shedding light on the interplay of the domain structure and phase transition.
    These results allow us to extract the different transition temperatures locally,
    to unveil the hysteresis behavior, and to determine the type of phase transition
    at play (first/second order) from the recorded SHGM data. The capabilities of
    SHGM in uncovering these crucial phenomena can easily be applied to other ferroelectrics
    to provide new possibilities for in situ engineering of advanced ferroic devices.
