From Mobility to Migration: Everyday Rural Life and the Formation of the Saxon–Bohemian Border Regime in the 19th Century

Contemporary Saxon immigration statistics noted a vast “floating population” in the multilocal and transregional border society of Upper Lusatia but did not consider them immigrants. Indeed, agricultural and factory workers – the majority of them women – showed a high level of mobility, some of them even on a daily basis. On the one hand, national authorities on both sides of the border struggled to categorize and control these short-distance and temporary, but widespread mobilities. Customs checks, on the other hand, gave rise to a personalised border control. These checks not only targeted the small-scale mobility that was highly common in the border region, but also promoted the establishment of sedentariness and border regulations as the normal scenario in local society. But it was not until the late 19th century that there was migration control with cultural and racist undertones.Contemporary Saxon immigration statistics noted a vast “floating population” in the multilocal and transregional border society of Upper Lusatia but did not consider them immigrants.

Feministisches Perlentauchen: Der META-Katalog und das Digitale Deutsche Frauenarchiv machen Materialien der Frauenbewegungen für die breite Öffentlichkeit sichtbar

Die Bewahrung der Lesben- und Frauenbewegungsgeschichte ist Aufgabe des i.d.a.-Dachverbands, der aktuell rund 40 Archive, Bibliotheken und Dokumentationsstellen vernetzt. Seit 2015 existiert der gemeinsame META-Katalog des Dachverbands. Er realisiert den spartenübergreifenden Nachweis von bibliothekarischen und archivalischen Materialien und stellt ein bisher einzigartiges Rechercheinstrument für die deutschsprachige Frauen- und Geschlechterforschung dar. Darauf aufbauend ging 2018 das Digitale Deutsche Frauenarchiv (DDF) online. Das virtuelle Portal präsentiert Originaldokumente in Form von Digitalisaten, begleitet von wissenschaftlich aufbereiteten Informationen. Der Beitrag widmet sich Herausforderungen beim Datenmanagement in META und bei der Rechteklärung für das DDF.Preserving the heritage of lesbian and women’s history is a major task of i.d.a., the umbrella organization of about 40 German-speaking lesbian/women‘s libraries, archives and documentation centres in Europe. Since 2015 the META-catalogue provides joint and multidisciplinary access to metadata and digital objects as a unique discovery tool for researchers in the fields of women and gender studies. As a follow-up project, the Digital German Women‘s Archive (DDF) went online in 2018. This virtual portal presents digitized documents accompanied by scholarly information. This article addresses the challenges of data management in META and rights clearance for the DDF

Variation of blubber thickness for three marine mammal species in the southern Baltic Sea

Evaluating populational trends of health condition has become an important topic for marine mammal populations under the Marine Strategy Framework Directive (MSFD). In the Baltic Sea, under the recommendation of Helsinki Commission (HELCOM), efforts have been undertaken to use blubber thickness as an indicator of energy reserves in marine mammals. Current values lack geographical representation from the entire Baltic Sea area and a large dataset is only available for grey seals (Halichoerus grypus) from Sweden and Finland. Knowledge on variation of blubber thickness related to geography throughout the Baltic Sea is important for its usage as an indicator. Such evaluation can provide important information about the energy reserves, and hence, food availability. It is expected that methodological standardization under HELCOM should include relevant datasets with good geographical coverage that can also account for natural variability in the resident marine mammal populations. In this study, seasonal and temporal trends of blubber thickness were evaluated for three marine mammal species—harbor seal (Phoca vitulina), grey seal (Halichoerus grypus) and harbor porpoise (Phocoena phocoena)—resident in the southern Baltic Sea collected and investigated under stranding networks. Additionally, the effects of age, season and sex were analyzed. Seasonal variation of blubber thickness was evident for all species, with harbor seals presenting more pronounced effects in adults and grey seals and harbor porpoises presenting more pronounced effects in juveniles. For harbor seals and porpoises, fluctuations were present over the years included in the analysis. In the seal species, blubber thickness values were generally higher in males. In harbor seals and porpoises, blubber thickness values differed between the age classes: while adult harbor seals displayed thicker blubber layers than juveniles, the opposite was observed for harbor porpoises. Furthermore, while an important initial screening tool, blubber thickness assessment cannot be considered a valid methodology for overall health assessment in marine mammals and should be complemented with data on specific health parameters developed for each speciesinfo:eu-repo/semantics/publishedVersio

Improved eV-scale sterile-neutrino constraints from the second KATRIN measurement campaign

We present the results of the light sterile neutrino search from the second Karlsruhe Tritium Neutrino (KATRIN) measurement campaign in 2019. Approaching nominal activity, 3.76×106 tritium β-electrons are analyzed in an energy window extending down to 40 eV below the tritium end point at E0=18.57  keV. We consider the 3ν+1 framework with three active and one sterile neutrino flavors. The analysis is sensitive to a fourth mass eigenstate m24≲1600  eV2 and active-to-sterile mixing |Ue4|2≳6×10−3. As no sterile-neutrino signal was observed, we provide improved exclusion contours on m24 and |Ue4|2 at 95% C.L. Our results supersede the limits from the Mainz and Troitsk experiments. Furthermore, we are able to exclude the large Δm241 solutions of the reactor antineutrino and gallium anomalies to a great extent. The latter has recently been reaffirmed by the BEST Collaboration and could be explained by a sterile neutrino with large mixing. While the remaining solutions at small Δm241 are mostly excluded by short-baseline reactor experiments, KATRIN is the only ongoing laboratory experiment to be sensitive to relevant solutions at large Δm241 through a robust spectral shape analysis

New Constraint on the Local Relic Neutrino Background Overdensity with the First KATRIN Data Runs

We report on the direct search for cosmic relic neutrinos using data acquired during the first two science campaigns of the KATRIN experiment in 2019. Beta-decay electrons from a high-purity molecular tritium gas source are analyzed by a high-resolution MAC-E filter around the end point at 18.57 keV. The analysis is sensitive to a local relic neutrino overdensity ratio of η < 9.7 × 10$^{10}$/α (1.1 × 10$^{11}$/α) at a 90% (95%) confidence level with α = 1 (0.5) for Majorana (Dirac) neutrinos. A fit of the integrated electron spectrum over a narrow interval around the end point accounting for relic neutrino captures in the tritium source reveals no significant overdensity. This work improves the results obtained by the previous neutrino mass experiments at Los Alamos and Troitsk. We furthermore update the projected final sensitivity of the KATRIN experiment to η < 1×10$^{10}$/α at 90% confidence level, by relying on updated operational conditions
