    Title translation Does the COVID-19 pandemic take its toll? The influence of COVID-19 induced anxiety on the social-emotional development of 12- to 13-year-olds in Austria.
    Abstract During the COVID-19 pandemic, students have been severely affected by measures such as school closures and homeschooling. While it is obvious that these measures influenced students' academic achievement, there is also reason to believe that students' social-emotional development has been impacted.The present study investigates (1) the extent to which students in Austrian secondary school (12 to 13 years old) feel stressed by the COVID-19 pandemic, and (2) how the different levels of stress affect their social-emotional development. The focus of this study is on the development of problematic behavior (internalized and externalized behavior problems) and prosocial behavior. In total, 774 students participated in the study and 650 students took part in three different times of measurement, with the last time of measurement taking place just before the second school closure as a measure in the COVID-19 pandemic.Almost 20% of the respondents show higher stress-levels in terms of COVID-19 induced anxiety. Students with higher stress-levels also display a more negative development in their internalized behavior problems. Likewise, for students' development of externalized behavior problems, a trend in this direction was demonstrated, yet less pronounced. Students who reported a higher stress-level also developed more prosocial behavior. Yet, we could not statistically verify this due to violation of statistical prerequisites.

    Abstract This article examines the photographic subject of the return of Austrian prisoners of war in the aftermath of the Second World War. Scholars and curators have singled out what are known as the 'homecomer' photographs by the Austrian photographer Ernst Haas, praising their artistic quality and assigning these works an iconic status. This approach has obscured the broader historical background of this subject as well as the editorial practices, collaborative efforts, and propagandistic intentions of these works in the field of photojournalism. In contrast, this article focuses on the immediate historical and political context of returning prisoner-of-war photographs in the Austrian illustrated press, arguing that they were part of a broad visual discourse deliberately adopted by the postwar media for the purposes of Cold War propaganda.

    Abstract Electrochemical impedance spectroscopy was used to investigate the chemical capacitance of La₀.₆Sr₀.₄CoO₃₋δ (LSC) thin-film electrodes under anodic polarization (i.e., in the electrolysis mode). For this purpose, electrodes with different microstructures were prepared via pulsed-laser deposition. Analysis of dense electrodes and electrodes with open porosity revealed decreasing chemical capacitances with increasing anodic overpotentials, as expected from defect chemical considerations. However, extremely high chemical capacitance peaks with values in the range of 10⁴ F/cm³ at overpotentials of >140 mV were obtained after annealing for several hours in synthetic air and/or after applying high anodic bias voltages of >750 mV. From the results of several surface analysis techniques and transmission electron microscopy, it is concluded that closed pores develop upon both of these treatments: (i) During annealing, initially open pores get closed by SrSO₄, which forms due to strontium segregation in measurement gases with minute traces of sulfur. (ii) The bias treatment causes mechanical failure and morphological changes including closed pores in the bulk of dense films. Under anodic polarization, high-pressure oxygen accumulates in those closed pores, and this causes the capacitance peak. Model calculations based on a real-gas equation allow us to properly predict the experimentally obtained capacitance increase. We demonstrate that analysis of the chemical capacitance of oxygen electrodes in solid oxide electrolysis cells can thus be used as a nondestructive observation tool to detect and quantify closed porosity with a lower detection limit between 10-⁴ and 10-³.
