abstract = {{Germany is experiencing a shortage of teachers, a situation that is particularly evident in the
domain of technical vocational education. In response to this, various pathways into vocational
teacher education have been established. These pathways are diverse in their nature but all lead to
the same teacher degree as traditional teacher education. In two interview studies (n=22 (pre
service) vocational teachers), initial motives of entering teacher education (based on FIT-Choice)
as well as retrospective views on the career choice after entering the profession (based on PLP
model) are analyzed. The present study compares the reflective views of pre-service teachers and
career-changing in-service teachers (CCIT). Although both groups generally perceive their career
choice positively, the results raise questions about why CCITs did not enter the field of teacher
education in the first place. Additionally, the analysis allows for further discussion about existing
teacher education programs in times of teacher shortage.}},

abstract = {{Three‐dimensional (3D) assemblies of gold nanoparticles (AuNPs) offer a rich platform for plasmonic coupling and near‐field engineering, yet their optical behavior is often complex due to structural disorder and fabrication‐induced variability. Here, we present a systematic optical investigation of large‐scale 3D AuNP assemblies fabricated via meniscus‐guided assembly, focusing on the reproducibility, spatial uniformity, and mode evolution of their plasmonic responses. Spatially‐resolved dark‐field scattering measurements reveal that high‐aspect‐ratio AuNP pillars exhibit uniform scattering spectra along their height and across different pillars, despite variations in geometry and structure. Electromagnetic simulations suggest that this robustness arises from a collective many‐particle plasmonic response that remains optically active despite structural perturbations. The corresponding near‐field and surface‐charge distributions remain spatially distributed under representative structural perturbations, consistent with volumetric averaging across the three‐dimensional assembly. Building on this robust platform, we introduce compositional modulation through a core–satellite architecture by incorporating smaller AuNPs. This yields a composition‐dependent spectral redistribution, including the emergence of an additional long‐wavelength spectral feature in the core–satellite assemblies. Wavelength‐dependent surface‐enhanced Raman scattering measurements reveal contrasting responses under 633 and 785 nm excitation, reflecting redistribution of local plasmonic coupling pathways. These results provide process‐enabled guidelines for using meniscus‐guided 3D‐nanoprinting to realize robust nanoparticle assemblies.}},

abstract = {{This study presents a numerical approach using a 3D finite element model to quantify the remaining clamp load of a plastic nut joint after a specific time. The viscoelastic relaxation of a thermoplastic nut, which is predominantly screwed on a welding stud, is described by a material card using Prony Series. Prony Series are derived from experimental dynamical mechanical analysis with different moisture and fiber contents of the thermoplastic. Since plastic nuts usually do not have preformed threads, the increased temperatures and resulting stresses from the thread-forming process are considered in the simulation. An FE model is created and verified by substrate stress relaxation tests. Experimental clamp load measurements with miniature compression load cells verify the clamp load prediction and show a good agreement. The developed model is used to analyze the clamp load distribution within the threads and reveals an almost even distribution within the threads.}},

abstract = {{Background: Agility is crucial in game sports, requiring both motor and cognitive skills. Athletes must perceive and process information to adapt movements, yet traditional agility tests often lack cognitive and multidirectional demands. Additionally, modern test systems are mostly stationary. This study evaluated the novel and portable “Functional Agility Square Test” (FAST) for validity, reliability, and usefulness. Methods: To assess discriminant validity, 22 game sports (GS) and 22 non-game sports (NGS) athletes participated in one session. Test–retest reliability was examined with 36 GS athletes (20 female) across three sessions. Participants performed cognitive (FAST_COG), preplanned (FAST_MOT), and randomized (FAST_SAT) reactive change-of-direction tasks, each repeated three times per session. Results: Results showed significantly lower response times (RTs) in GS compared to NGS (p < 0.05). Mean RTs indicated moderate relative reliability (ICC 0.50–0.74), while medians showed moderate to good reliability (ICC 0.59–0.83). Usefulness was evident from the first session (FAST_MOT) or from the third session (FAST_SAT) based on median RTs. Conclusions: Thus, the FAST seems to be valid, reliable, and sensitive for GS-based agility assessment. Its portable setup enables ecologically valid field testing. Future research should further increase task complexity to better simulate game conditions.}},

abstract = {{The LLC converter achieves the highest efficiency in resonant operation. Conventionally, the input DC-link voltage is controlled to operate the LLC converter at resonance for the given operating point. However, the DC-link capacitor voltage shows a low-frequency voltage ripple (typically the second harmonic of grid frequency) in cascaded converters so that the LLC has to adapt its switching frequency within the grid period. Conventionally, the LLC converter operates 50% of the time above the resonant frequency of 40 kHz and 50% below resonance. Both operating conditions cause additional losses. However, experimental measurements indicate that the below-resonance operation causes significantly higher losses than above-resonance operation due to much higher primary and secondary transformer currents. It is better to increase the DC-link voltage by 30% of the peak-to-peak low-frequency voltage ripple to mostly avoid below-resonance operation (i.e., from 650 V to 680 V in this case). With the proposed control, the LLC converter operates about 75% of time over resonance and only 25% of time below resonance. The overall efficiency increases from 97.66% to 97.7% for the average operating point with an 80% load current. This corresponds to a 2% total loss reduction. Finally, the peak resonance capacitor voltage decreases from 910 V to 790 V (−13%).}},

abstract = {{Zusammenfassung
Die fortschreitende Digitalisierung stellt Schulen vor Herausforderungen, insbesondere bei der Nutzung digitaler Medien in unterrichtlichen Lehr- und Lernprozessen mit dem Ziel, den (über-) fachlichen Kompetenzerwerb aller Schüler*innen zu unterstützen. Betrachtet man die digitalen Kompetenzen, zeigt sich, dass auch diese sozialen Disparitäten unterliegen. Dennoch lassen sich in ICILS organisational resiliente Schulen identifizieren, deren Schüler*innen trotz herausfordernder Schüler*innenkomposition überdurchschnittliche digitale Kompetenzen erreichen. Studien, die fachspezifische Kompetenzen untersuchen, lassen erkennen, dass organisational resiliente Schulen gemeinsame Merkmale aufweisen. Ein Merkmal, das in diesem Zusammenhang bedeutsam erscheint, ist die Gestaltung von Unterrichtsqualitätsmerkmalen. Digitale Kompetenzen erscheinen diesbezüglich unerforscht, sodass der vorliegende Beitrag mittels Daten aus der BMBF-geförderten qualitativen ICILS-Vertiefungsstudie UneS-ICILS 2018 (Unerwartbar erfolgreiche Schulen im digitalen Wandel) Basisdimensionen von Unterrichtsqualität an resilienten Schulen in Bezug auf digitale Kompetenzen untersucht. Für die Analyse wurden 22 leitfadengestützte Interviews mit Lehrkräften und sieben Gruppeninterviews mit Schüler*innen im Hinblick auf eine ‚effiziente Klassenführung‘, ‚kognitive Aktivierung‘ und ‚konstruktive Unterstützung‘ inhaltsanalytisch ausgewertet. Im Ergebnis zeigt die Analyse der Dimension ‚effiziente Klassenführung‘, dass sich u. a. die Organisation und Struktur mittels digitaler Medien wie beispielsweise durch den Einsatz digitaler Lernplattformen als bedeutende Faktoren herausstellen. Hinsichtlich der ‚kognitiven Aktivierung‘ wird der Einsatz digitaler Tools für das Anknüpfen an individuelles Vorwissen als bedeutend hervorgehoben. Darüber hinaus zeigt sich bei der Dimension ‚konstruktive Unterstützung‘ die Förderung des selbstgesteuerten Lernens und das Ausbilden von Unterstützungsstrukturen zum (kooperativen) Lernen mit digitalen Medien als bedeutsam. Induktiv ergänzt wurde die Dimension ‚Inhaltswahl und selektive Fokussierung‘, die die hohe Relevanz des Erwerbs digitaler Kompetenzen im Unterricht an den resilienten Schulen verdeutlicht.}},

abstract = {{ABSTRACT
Effective manipulation of photonic spin–orbit coupling (SOC) in microcavities is of fundamental importance within topological photonics and applications. Anisotropic organic single‐crystalline materials can induce abundant SOC phenomenon due to their flexible tunability of molecular geometries, however, the intrinsic relationship between molecular geometries/orientations in 3D space and photonic SOC is lacking. In this study, we design two kinds of 2D organic polymorphs for the construction of organic microcavities to investigate the structure‐performance relationships. In two polymorphic microcavities, two distinctive photonic SOC phenomena are observed regardless of the in‐plane anisotropy of organic polymorphs. Theoretical analysis indicates that the photonic SOC strength is strongly influenced by the synergies between the crystal anisotropy and the tilted collective molecular transition dipole moment. Our results uncover the correlation mechanism between the structure of molecules and photonic SOC and open an avenue to engineer complex photonic SOC by use of organic microstructures towards the development of diverse integrated photonic devices.}},
