H.E.S.S. observations were accompanied or preceded by multiwavelength observations with Fermi/LAT, XRT and UVOT onboard the Swift satellite, and ATOM. Based on an extrapolation of the Fermi/LAT spectrum towards the VHE gamma-ray regime, we deduce a 95 per cent confidence level upper limit on the unknown redshift of KUV 00311-1938 of z < 0.98 and of PKS 1440-389 of z < 0.53. When combined with previous spectroscopy results, the redshift of KUV 00311-1938 is constrained to 0.51 <= z < 0.98 and of PKS 1440-389 to 0.14 (sic) z < 0.53.}, language = {en} } @article{AbdelilahSeyfriedIruelaArispePenningeretal.2022, author = {Abdelilah-Seyfried, Salim and Iruela-Arispe, M.

The results show a shift from ERP code modification in on-premises systems to interface and integration customization in cloud ERP systems, as well as emerging technological opportunities as a way for customers and key users to perform system customization.

And how do topics discussed change over time? The study leans on the goals associated with the health information seeking (GAINS) model, discerning whether a post aims at tackling and eliminating the problem (i.e., problem-focused) or managing the emotions (i.e., emotion-focused); whether it strives to maximize positive outcomes (promotion focus) or to minimize negative outcomes (prevention focus). The findings indicate four clusters salient in public reactions: 1) "Understanding" (problem-promotion); 2) "Action planning" (problem-prevention); 3) "Hope" (emotion-promotion) and 4) "Reassurance" (emotion-prevention). Public communication is volatile over time, and a shift is evidenced from self-centered to community-centered topics within 4.5 weeks. Our study illustrates social media text mining's potential to quickly and efficiently extract public opinions and reactions. Monitoring fears and trending topics enable policymakers to rapidly respond to deviant behavior, like resistive attitudes toward containment measures or deteriorating physical health.

In den Modernisierungsprozessen stehen derzeit zwei Segmente besonders im Fokus: Digitalisierung und Partizipation. Digitalisierung geht heute weit {\"u}ber die urspr{\"u}nglich mit diesem Stichwort angesprochene Umwandlung analoger Daten in elektronische Datenformate hinaus. Die Programmatik der Digitalisierung zielt auf den m{\"o}glichst umfassenden Einsatz elektronischer Informations- und Kommunikationstechniken zur Unterst{\"u}tzung, Beschleunigung, Rationalisierung und in Teilen auch Ersetzung von herk{\"o}mmlichen Verwaltungsabl{\"a}ufen mit der Perspektive auf eine Transformation und Durchdringung sowohl des gesamten Verwaltungshandelns als auch der gesamten Verwaltungsorganisation. Demgegen{\"u}ber meint Partizipation nach g{\"a}ngigem Verst{\"a}ndnis die Beteiligung von B{\"u}rgern und anderen gesellschaftlichen Akteuren an politischen Willensbildungs- und Entscheidungsprozessen. In spezifisch administrativem Zusammenhang geht es vor allem um die Einbindung von B{\"u}rgern in Entscheidungsprozesse der Verwaltung und um die Aktivierung der Zivilgesellschaft, die Erschließung b{\"u}rgerschaftlichen Engagements sowie gesellschaftlicher Ressourcen f{\"u}r die Erf{\"u}llung von Verwaltungsaufgaben - und dies alles mit dem Ziel einer Verbesserung der Legitimit{\"a}t und Qualit{\"a}t {\"o}ffentlicher Verwaltung. Die beiden Modernisierungsans{\"a}tze stehen nicht unverbunden nebeneinander. Vielmehr gehen sie nicht selten ineinander {\"u}ber.
