Wie die gesundheitlichen Folgen der Pandemie von sozialen Ungleichheiten abhängen - und was wir daraus lernen sollten
No full textJan Paul Heisig richtet den Blick in seinem Beitrag darauf, inwieweit einzelne Gruppen von dem Virus betroffen sind, wenn man nach sozioökonomischen Merkmalen und nach ethnischer Zugehörigkeit unterscheidet. Aus den wirtschaftlichen und ethnischen Unterschieden, die schon vor der Pandemie bestanden, ergeben sich in Bezug auf die Ausbreitung des Virus und die damit zusammenhängenden negativen Auswirkungen eindeutige Abweichungen zwischen bestimmten Bevölkerungsgruppen

Indirect dark-matter detection with MadDM v3.2 -- Lines and Loops
No full textAutomated tools for the computation of particle physics' processes have
become the backbone of phenomenological studies beyond the standard model.
Here, we present MadDM v3.2. This release enables the fully automated
computation of loop-induced dark-matter annihilation processes, relevant for
indirect detection observables. Special emphasis lies on the annihilation into
, where or any new particle even under the dark
symmetry. These processes lead to the sharp spectral feature of monochromatic
gamma lines -- a smoking-gun signature of dark matter in our Galaxy. MadDM
provides the predictions for the respective fluxes near-Earth and derives
constraints from the gamma-ray line searches by Fermi-LAT and HESS. As an
application, we discuss the implications for the viable parameter space of a
top-philic -channel mediator model and the inert doublet model.Comment: 21 pages + references; Minor changes in presentation, references

Future caregiving responsibilities, employment uncertainties, and expected childbearing behavior: survey experimental evidence from Germany
No full textIn societies experiencing declining birth rates, understanding factors that influence childbearing decisions is of interest. We used a factorial survey experiment to investigate how scenarios of future caregiving responsibilities toward aging parents and employment uncertainties shape the expected childbearing behavior of a fictitious couple. Respondents from the nationally representative German Socio-Economic Panel Innovation Sample (SOEP-IS) (n = 1,750) were randomly assigned to five vignettes, each describing a hypothetical couple with varying levels of caregiving responsibilities towards an aging parent and employment uncertainties. Respondents subsequently rated their expectations about the hypothetical couple’s childbearing behavior within the next three years using an 11-point scale. Results show that high caregiving responsibilities and dual employment uncertainties reduce expected childbearing behavior by 2.8 and 1.9 units respectively, compared to when these are absent. The negative effect of high caregiving responsibilities is more pronounced among women, while respondents’ own caregiving and employment experiences do not moderate these effects. These results demonstrate how both future-oriented caregiving responsibilities and employment uncertainties alter expectations about family formation and highlight the scenarios that are regarded as more or less favorable for childbearing
