    that a significant majority of parents advocate for an early\r\n\t\t\t\t\t\t\t\tstart
    in year 1 or 2 of primary school, generally aligning with\r\n\t\t\t\t\t\t\t\ttheir
    strong conviction of the importance of English, high\r\n\t\t\t\t\t\t\t\teducational
    aspirations and expectations, and their own (early)\r\n\t\t\t\t\t\t\t\tstart of
    language education. The findings contribute to a deeper\r\n\t\t\t\t\t\t\t\tunderstanding
    of parental perspectives that have also shown to be\r\n\t\t\t\t\t\t\t\trelated
    to multiple indicators of educational success in general and\r\n\t\t\t\t\t\t\t\tachievements
    in language learning in particular.</jats:p>"

  text: <jats:title>ABSTRACT</jats:title><jats:p>The use of digital tools for second
    and foreign language lexical learning is increasingly popular and research in
    this area is constantly expanding. However, little has been written about specific
    criteria that could be used to identify tools with high‐quality lexical input,
    as available checklists and frameworks for digital media tend to neglect detailed
    analyses of the vocabulary domain. This article addresses this issue by presenting
    the Checklist for Evaluating Digital Resources for Lexical Learning (DigiLex),
    which combines important digital language learning criteria with an extensive
    evaluation of lexical content. The checklist is both theory‐based and user‐friendly,
    aiming to fill a gap between theory and practice in the field of digital lexical
    learning. The article discusses the theoretical basis of the checklist and integrates
    the results of a small pilot study with pre‐service and in‐service teachers, emphasizing
    feasibility in everyday learning and teaching. By providing an easy‐to‐use tool
    for identifying suitable digital resources, the DigiLex checklist aims to support
    language learners and teachers in self‐regulated lexical learning.</jats:p>

  text: <jats:p>Titanium alloys are widely employed for biomedical implants due to
    their high strength, biocompatibility, and corrosion resistance, yet their lack
    of intrinsic antibacterial activity remains a major limitation. Incorporating
    copper, an antibacterial and β-stabilising element, offers a promising strategy
    to enhance implant performance. This study investigates Ti-6Al-7Nb modified with
    1–9 wt.% Cu via in situ alloying during metal-based laser powder bed fusion (PBF-LB/M),
    with the aim of assessing processability, microstructural evolution, and mechanical
    properties. Highly dense samples (&gt;99.9%) were produced across all Cu levels,
    though chemical homogeneity strongly depended on processing parameters. Increasing
    Cu content promoted β-phase stabilisation, Ti2Cu precipitation, and pronounced
    grain refinement. Hardness and yield strength increased nearly linearly with Cu
    addition, while ductility decreased sharply at ≥5 wt.% Cu due to intermetallic
    formation, hot cracking, and brittle fracture. These results illustrate both the
    opportunities and constraints of rapid alloy screening via PBF-LB/M. Overall,
    moderate Cu additions of 1–3 wt.% provide the most favourable balance between
    mechanical performance, manufacturability, and potential antibacterial functionality.
    These findings provide a clear guideline for the design of Cu-functionalised titanium
    implants and demonstrate the efficiency of in situ alloy screening for accelerated
    materials development.</jats:p>

  text: "The carbon footprint of modern vehicles and their mechatronic systems is
    more\r\nimportant than ever. Research by the publicly funded Nalyses project and
    the HELLA\r\ncompany shows that the headlamps use phase makes a significant contribution
    to the life\r\ncycle footprint taking into account the current electricity mix
    [1]. Today, functionalities\r\nsuch as adaptive curve light or glare-free high
    beam ensure comfort and safety by\r\nassessing the state of the vehicle and evaluating
    the driving scenario ahead. In future,\r\nthis evaluation will be expanded and
    used to adapt the headlamp to the driving scenario\r\nin such a way that as little
    light as possible is emitted, but as much light as necessary. In\r\norder to achieve
    this goal, an overall evaluation of the regulatory compliant energy\r\nsaving
    potential is crucial in a first step and leads to constraints for a dynamic adaption\r\nwhile
    driving. In this paper, the potential is illustrated by evaluating UNECE Regulation\r\nNo.
    149 and optimizing luminous intensity distributions. Depending on the different\r\nresolutions
    of matrix LED headlamps, this approach can result in a significantly lower\r\nluminous
    flux. On the other hand, the results are point-like distributions that raise the\r\nquestion
    of whether the regulation still provides for sensible minimum requirements for\r\nmodern
    matrix LED headlamps. The results are further presented in a simulated virtual\r\nenvironment
    with regard to the resulting luminance in different driving scenarios. We\r\nthen
    present an approach to integrate regulatory requirements into a control algorithm
    by\r\nsetting optimization constraints and saturating the control. Finally, we
    classify the found\r\nluminous intensity distributions qualitatively according
    to common lighting criteria. In summary, although the investigated minimum distributions
    are by no means desirable\r\nfor drivers themselves, they form the basis on which
    energy-saving distributions for\r\nilluminated areas and twilight scenarios could
    be adaptively controlled in the future."

  text: Im Beitrag wird die professionelle Unterrichtswahrnehmung von (angehenden)
    Lehrkräften bezogen auf die Anforderungssituation 'Gemeinsam Gespräche moderieren'
    im Kontext des flexiblen Rechnens in Jahrgangsstufe 1 betrachtet. Die Studie untersucht
    mittels Videovignetten expertise-bezogene Unterschiede in der professionellen
    Wahrnehmung, indem je 10 angehende und erfahrene Mathematiklehrkräfte betrachtet
    werden. Die zunächst inhaltsanalytisch ausgewerteten Daten der beiden Gruppen
    werden mittels der epistemischen Netzwerkanalyse verglichen. Es werden erste Ergebnisse
    berichtet.

  text: raditional assessment formats in university-based EFL teacher education programs
    usually focus on cognitive dispositions rather than on the actual performance
    of pre-service EFL teachers in everyday teaching situations. This assessment gap
    is addressed in this thesis by developing and validating a role-play-based simulation
    (RobS) designed for the summative assessment of pre-service EFL teachers' feedback
    competence on writing. Drawing on theories from multiple disciplines, such as
    higher education, medical education, teacher education, educational psychology,
    and EFL-specific didactics, the RobS is developed as a performance-oriented assessment
    format. In the RobS, pre-service EFL teachers engage in a feedback conversation
    with trained actors who portray a standardized learner. Following an argument-based
    approach to validation, the extent to which the RobS can be considered valid is
    investigated. Data from multiple studies, focusing on aspects such as authenticity,
    fairness, reliability, and external validity, are presented. The discussion in
    the validity argument indicates that the RobS can elicit and assess the performative
    facet of feedback competence on writing with sufficient confidence. This work
    contributes a novel, empirically supported assessment framework to teacher education
    research. Moreover, it presents an approach to address the assessment gap, enabling
    pre-service EFL teachers to show how they provide feedback, rather than just tell
    their lecturers about it.

  text: "<jats:p>\r\n                    Lateral ankle sprain (LAS) is the most common
    traumatic injury, with a high recurrence rate and chronic ankle instability (CAI)
    developing in ∼40% of cases. LAS leads to patho-mechanical, sensory-perceptual
    and motor-behavioral deficits. Poor management of the return-to-sport (RTS) is
    now considered a major cause of re-injury and development of CAI, particularly
    due to the lack of validated tests and the failure of existing ones to account
    for those central deficits. The first part of this topic aimed to clarify concepts
    of cognitive constructs and sensory reweighting and their association with CAI.
    We also aimed to identify objective RTS criteria and discuss their limits regarding
    their ability to encompass central impairments. Motor-cognitive deficits have
    been identified using computerized cognitive tasks and dual-task paradigms. More
    specifically, deficits in visual memory, processing speed or inhibitory control
    and attentional resource allocation have demonstrated reduced performance in CAI
    populations. In addition, altered sensory reweighting process towards visual input
    has also been observed. While objective criteria are crucial to prevent re-injury,
    current evaluations remain largely subjective and central impairments are unaccounted
    for in conventional RTS testing. The Ankle-GO\r\n                    <jats:sup>TM</jats:sup>\r\n
    \                   score was recently developed to guide clinicians in decision
    making process. To date, it is the first validated score that could help to identify
    patients who will RTS at the same level, those at risk of recurrence and those
    who are more likely to become copers. Unfortunately, it does not target cognitive
    or sensory reweighting alterations, that are both relevant in sport to manage
    gameplay demands.\r\n                  </jats:p>"

  text: <jats:p>Abstract. In the field of online condition monitoring, non-destructive
    testing methods using active acoustic testing [1] emerged as innovative tools.
    These techniques are particularly effective because damage in joined structures
    leads to significant changes in their vibrational characteristics. However, the
    consistent use of online condition monitoring through active acoustic testing
    combined with complex pattern recognition for early crack detection in joined
    components has not yet been fully established. This research aims to develop an
    online crack detection system employing pattern recognition techniques under cyclic
    loading during fatigue tests, utilizing non-contact active acoustic testing with
    laser vibrometry. Due to the wide range of materials that can be joined, mechanical
    joining processes can be used in many different industry branches. Self-pierce
    riveting (SPR), in particular, is a well-established joining process. Therefore,
    the investigations for online crack detection initially focus on SPR joints. To
    achieve this, the fatigue behavior of SPR joints in a lap-shear configuration
    was characterized. Experimental fatigue testing demonstrated that SPR joint failure
    occurs either through cracks propagating in the sheet material away from the rivet
    or in the rivet foot, depending on the material combination. Laser vibrometry
    has been successfully used as a crack detection system and has proven to be effective
    in detecting crack initiation in SPR joints. Cracks can be detected without contact
    regardless of the material combination, the damage location, the size of the damage,
    or the type of damage.  The optimization of the crack detection system involved
    several key enhancements, including adjusting data acquisition to improve crack
    detection, incorporating principal component analysis (PCA) to reduce dimensionality,
    and implementing a classification model based on a global training dataset. An
    intuitive, problem-specific software demonstrator for analyzing the crack initiation
    behavior of SPR joints under cyclic loading was developed and iteratively optimized.
    Future work will focus on the implementation of an autoencoder network to further
    enhance crack detection capabilities.</jats:p>
