Prioritizing Urinary Incontinence for Current and Future Healthcare Professionals
Introduction: âąUrinary incontinence (UI) is a common syndrome that often goes unreported and undiagnosed âąAs calls to action from the National Institute on Aging and American Geriatrics Society suggest, the healthcare workforce must work interprofessionally to meet the needs of people with UI âąUnderstanding the challenges of and opportunities for improving continence care in Virginia is a first step âąThe primary goal of this study was to assess changes in awareness of and confidence in providing interprofessional UI care after participating in an interactive worksho
Streaking and Wigner time delays in photoemission from atoms and surfaces
Streaked photoemission metrology allows the observation of an apparent
relative time delay between the detection of photoelectrons from different
initial electronic states. This relative delay is obtained by recording the
photoelectron yield as a function of the delay between an ionizing ultrashort
extended ultraviolet (XUV) pulse and a streaking infrared (IR) pulse.
Theoretically, photoemission delays can be defined based on i) the phase shift
the photoelectron wavefunction accumulates during the release and propagation
of the photoelectron (``Wigner delay") and, alternatively, ii) the streaking
trace in the calculated photoemission spectrum (``streaking delay"). We
investigate the relation between Wigner and streaking delays in the
photoemission from atomic and solid-surface targets. For solid targets and
assuming a vanishing IR-skin depth, both Wigner and streaking delays can be
interpreted as an average propagation time needed by photoelectrons to reach
the surface, while the two delays differ for non-vanishing skin depths. For
atomic targets, the difference between Wigner and streaking delays depends on
the range of the ionic potential.Comment: 9 pages, 12 figures, submitted to Phys. Rev.
Status report of the CERN light shining through the wall experiment with microwave axions and related aspects
One way to proof or exclude the existence of axion like particles is a
microwave light shining through the wall experiment. In this publication we
will emphasize on the engineering aspects of such a setup, currently under
development at CERN. One critical point, to achieve meaningful results, is the
electromagnetic shielding between axion-emitter and -receiver cavity, which
needs to be in the order of 300 dB to improve over existing experimental
bounds. The RF leakage or electromagnetic crosstalk between both cavities must
be well controlled and quantified during the complete duration of the
experiment. A very narrow band (in the 10^-6 Hz range) homodyne detection
method is used to reveal the axion signal from background thermal noise. The
current status of the experiment is presented.Comment: Contributed to the "7th Patras Workshop on Axions, WIMPs and WISPs",

Status report and first results of the microwave LSW experiment at CERN
To detect or exclude the existence of hidden sector photons or axion like
particles, a table-top "microwaves shining through the wall" experiment has
been set up at CERN. An overview of the experimental layout is given, the
technical challenges involved are reviewed and the measurement procedure
including data-evaluation and its results to date are shown.Comment: Contributed to the 8th Patras Workshop on Axions, WIMPs and WISPs,

Aus Liebe sterben : Inszenierung und Perspektivierung von Elyes Liebestod in Rudolfs von Ems âșWillehalm von Orlensâč
[D]ie Schlusspartie im ersten Buch des âșWillehalm von Orlensâč Rudolfs von Ems [âŠ] beginnt unmittelbar mit der breit geschilderten Totenklage ĂŒber den ermordeten FĂŒrsten Wilhelm [âŠ]. Mitten in diesem Leid, das in Rede und GebĂ€rde zum Ausdruck gebracht wird, geschieht im âșWillehalm von Orlensâč das AuĂerordentliche: Elye, Wilhelms Frau, stirbt aus ĂŒbergroĂem Schmerz an der Leiche ihres Mannes. Obwohl solch ein âTod an gebrochenem Herzenâ auĂerhalb der normalen lebensweltlichen Erfahrung steht und als Faktum des Sterbens an sich keine âmoralischeâ Komponente beinhaltet, birgt er ein gewisses Konfliktpotenzial [âŠ].
Wie versucht nun der Text diesen beunruhigenden, âunfassbarenâ Tod literarisch darzustellen und damit fassbar zu machen? Werden die Wertekonflikte, die bei jedem Liebestod unweigerlich mitschwingen, angesprochen, beurteilt und wird versucht, sie zu harmonisieren? Diese Fragen werden umso brisanter, gerade wenn man die generell didaktische Tendenz des Romans berĂŒcksichtigt, der in der Forschung als âFĂŒrstenlehreâ fĂŒr den jungen
Staufer Konrad IV. gilt. Eine Antwort darauf lohnt sich in den Klagen zu suchen, die den Liebestod von der HandlungsfĂŒgung her umrahmen. Sie finden sich im âșWillehalm von Orlensâč auf verschiedene Personen aufgeteilt: die Perspektive auf den Tod resp. Liebestod vervielfĂ€ltigt sich, dieser gewinnt unter den verschiedenen Blickwinkeln unterschiedliche Facetten â so auch seine Bewertung. [âŠ] Daneben ist es aber fĂŒr ein erweitertes VerstĂ€ndnis von Aussage und Funktion unabdingbar zu erörtern, w i e diese Klagen âin Szeneâ gesetzt werden, d. h. wie sie und die klagenden Personen im Diskurs zur Darstellung kommen: Erst in dieser Zusammenschau darf man eine ĂŒber die Textebene hinausreichende Interpretation der Bewertung der Liebestodproblematik in dieser Textpassage versuchen und damit eine mögliche Antwort auf die Frage finden, welche âLehreâ denn die ErzĂ€hlung und Kommentierung der Ereignisse rund um Elyes Liebestod transportieren könnten
