Theorie der (literarischen) Satire:Ein funktionales Modell zur Beschreibung von Textstruktur und kommunikativer Wirkung
Das entworfene Modell der literarischen Satire geht davon aus, dass satirische Kommunikation innerhalb der institutionalisierten Handlungen literarischer Kommunikation durch eine besondere Funktionalisierung von textuellem System und außertextuellen Bezügen gekennzeichnet ist, die für die Textstruktur Relevanz hat. Der Beitrag verfolgt dabei auch ein theorie- und fachgeschichtliches Ziel und dokumentiert, wie in den späten 1960er und im Laufe der 1970er Jahre in der deutschsprachigen Literaturwissenschaft für den Gegenstandsbereich ›Theorie und Geschichte der Satire‹ der Anschluss an die internationale Diskussion hergestellt wurde

Nuclear matrix elements for neutrinoless double-beta decay and double-electron capture
A new generation of neutrinoless double beta decay experiments with improved
sensitivity is currently under design and construction. They will probe
inverted hierarchy region of the neutrino mass pattern. There is also a revived
interest to the resonant neutrinoless double-electron capture, which has also a
potential to probe lepton number conservation and to investigate the neutrino
nature and mass scale. The primary concern are the nuclear matrix elements.
Clearly, the accuracy of the determination of the effective Majorana neutrino
mass from the measured 0\nu\beta\beta-decay half-life is mainly determined by
our knowledge of the nuclear matrix elements. We review recent progress
achieved in the calculation of 0\nu\beta\beta and 0\nu ECEC nuclear matrix
elements within the quasiparticle random phase approximation. A considered
self-consistent approach allow to derive the pairing, residual interactions and
the two-nucleon short-range correlations from the same modern realistic
nucleon-nucleon potentials. The effect of nuclear deformation is taken into
account. A possibility to evaluate 0\nu\beta\beta-decay matrix elements
phenomenologically is discussed.Comment: 24 pages; 80 references. arXiv admin note: substantial text overlap

The -cleus experiment: A gram-scale fiducial-volume cryogenic detector for the first detection of coherent neutrino-nucleus scattering
We discuss a small-scale experiment, called -cleus, for the first
detection of coherent neutrino-nucleus scattering by probing nuclear-recoil
energies down to the 10 eV-regime. The detector consists of low-threshold
CaWO and AlO calorimeter arrays with a total mass of about 10 g and
several cryogenic veto detectors operated at millikelvin temperatures.
Realizing a fiducial volume and a multi-element target, the detector enables
active discrimination of , neutron and surface backgrounds. A first
prototype AlO device, operated above ground in a setup without
shielding, has achieved an energy threshold of eV and further
improvements are in reach. A sensitivity study for the detection of coherent
neutrino scattering at nuclear power plants shows a unique discovery potential
(5) within a measuring time of weeks. Furthermore, a site
at a thermal research reactor and the use of a radioactive neutrino source are
investigated. With this technology, real-time monitoring of nuclear power
plants is feasible.Comment: 14 pages, 19 figure
