The Influence of global Crises on Acceptance of Autocracy in Germany. Paper presented at the 25th Annual Conference of the European Society of Criminology, September 3-6, 2025 in Athens (Greece)
No full textThis paper investigates how global conflicts and crises influence public attitudes toward democracy in Germany, particularly fears related to war, climate change, and migration. As part of the study "People in Germany: International", online surveys are conducted every two to three months. Our data tracks how perceptions of societal challenges and associated concerns shape attitudes toward democracy over time. A new measurement is used to gauge acceptance of autocracy, defined by the rejection of democratic norms like open debate and parliamentary oversight, and support for more authoritarian leadership. Results indicate that about 30% of the German population exhibits some level of autocracy acceptance, with variations across political affiliations—from 14.8% among Green Party voters to 50.1% among AfD (a far right party) supporters. Acceptance of autocracy is not confined to right-wing or lower-educated groups but spans various social demographics. Concerns over access to necessities—housing, energy, work, and food—aggravated by fears of war, climate change, or migration, increase the likelihood of supporting autocracy. Those who view political leaders as incompetent are even more inclined toward authoritarian preferences

Multispectral Imaging Data of Torah scroll "Vat. Ebr. 2" captured at Biblioteca Apostolica Vaticana
No full textThis multispectral data of the Torah scroll "Vat. Ebr 2" was captured at the Biblioteca Apostolica Vaticana in June 2023. The goal of the imaging session was to visualize reinked letters, corrections and other otherwise invisible features of the scroll. The MSI images are intended to help choose smaller areas and spots for measurements with XRF, Raman or FTIR. Additionally, they provide information about the conservation condition, for example displaying levels of mold damage. The scroll was previously digitized in great resolution from both sides. Link to digitized scroll (Biblioteca Apostolica Vaticana) In this MSI campaign only the text side of the scroll was imaged. The MSI campaign was co-organised by the Biblioteca Apostolica Vaticana, the Centre for the Study of Manuscript Cultures (CSMC), the Bundesanstalt für Materialforschung und -prüfung (BAM). Imaging was carried out using the CSMC MegaVision multispectral imaging system. The MSI system was operated by the CSMC staff, the scroll was handled by the staff of the Vatican Library digitization and conservation departments. (See contributors)
Preview JPEGs in sRGB color space are compressed and of lower quality and are only intended for quick previewing. Original, high quality, CIELAB TIF images can be found in the PROCESSED folders within each ZIP file. Each uploaded ZIP file contains the flattened, processed and color images for a single sheet of the scroll. Raw images are not included in this dataset simply for size reduction purposes. Raw images are stored internally on the servers of CSMC and, if necessary, can be separately accessed upon a reasonable request. For information about filenames and folder structure as well as MSI system, please see the files in the "info" folder and read the Brief Descriptions of Multispectral Imaging (MSI) Datasets.
Image processing was performed with Hoku image processing software. In each processed folder there are 6 images. A visible light color image called "PSC", an image highlighting the reinking called "Reinking", an image highlighting the texture called "Texture", an image showing the mold damage on sheets where mold is present called "Mold", as well as two pseudocolor images called "UVB_Composite" showing fluorescing materials present on the sheets and a "Pseudocolor" image which color-codes the reinking in blue and red for better visibility and as an alternative to the greyscale "Reinking" image
X-Ray Fluorescence and Reflectography Data from Hamburg, Staats- und Universitätsbibliothek Hamburg Carl von Ossietzky, P. graec. 184.I

P. graec. 184 I (P. Hamb. I 39, Tm 44371, Rom. Mil. Rec. 1.76_44-45) is a fragment of a 4,33 m long roll with receipts for faenarium (payments for hay) for Roman soldiers of the ala veterana Gallica. The inks are carbon-based, containing various amounts of copper (Cu).

Landsat-1 Multispectral Scanner surface type over water from supervised classification of surface broadband albedo estimates
No full textAbstract: In the framework of the European Space Agency (ESA) Climate Change Initiative (CCI+) sea ice essential climate variable (ECV) project phase 2, Landsat-1 Multispectral Scanner (MSS) images were obtained from https://earthexplorer.usgs.gov/ for both hemispheres with the purpose to evaluate the ESA CCI+ Nimbus-5 Electrically Scanning Microwave Radiometer (ESMR) sea-ice concentration data product v1.1. From these Landsat-1 MSS images surface broadband albedo values were estimated based on channels 4 to 7 (mostly 4, 5, and 7). Secondly, a supervised classification was employed, classifying the broadband albedo maps into open water, thin/bare ice, and thick/snow-covered ice using simple threshold values selected based on visual manual interpretation of the images. Thresholds used for this classification are provided in the metadata txt-file along with the data. MSS images have been pre-processed and quality assessed as much as possible to avoid artefacts from missing and/or corrupt scanlines and clouds or cloud shadows.
