Health Systems Global, the new international society for health systems research
I see starting a new international society for health systems research as a step towards renewing our collective commitment to global health goals; in particular I see the proposed society as marking a commitment to equitable universal health care. From my perspective it is important that we are clear on the values that underpin the development of this new society. In addition, the society needs a clear strategy to help achieve this goal, in particular we need to first identify who is the target audience or constituency for the society; and second, the tools through which the society will work and how the society will engage with its audience.Fil: Kraushaar, D..

LiST as a catalyst in program planning: experiences from Burkina Faso, Ghana and Malawi
Background African countries are working to achieve rapid reductions in maternal and child mortality and meet their targets for the Millennium Development Goals (MDGs). Partners in the Catalytic Initiative to Save One Million Lives (CI) are assisting them by providing funding and technical assistance to increase and accelerate coverage for proven interventions. Here we describe how the Lives Saved Tool (LiST) was used as part of an early assessment of the expected impact of CI plans in Malawi, Burkina Faso and Ghana
Head of State of Exception
During the escalation of the “German Autumn” in 1977 the Federal German government resorted to a specific form of crisis management that had been described as an undeclared state of exception. It was Federal chancellor Helmut Schmidt in the first place who oversaw the anti-terrorist measures in the situation room where the executive branch ruled for six weeks beyond any parliamentary control. This article examines the role that Helmut Schmidt had played for the creation of a “subjective state of exception” (Julius Hatschek) and how this could be seen as stemming from Schmidt’s earlier experiences and handling of crisis situations dating back to the 1960s. In this regard it has to be asked with Giorgio Agamben, if in the West German case, the state of exception had become the rule
Energy Dependence of the NN t-matrix in the Optical Potential for Elastic Nucleon-Nucleus Scattering
The influence of the energy dependence of the free NN t-matrix on the optical
potential of nucleon-nucleus elastic scattering is investigated within the
context of a full-folding model based on the impulse approximation. The
treatment of the pole structure of the NN t-matrix, which has to be taken into
account when integrating to negative energies is described in detail. We
calculate proton-nucleus elastic scattering observables for O,
Ca, and Pb between 65 and 200 MeV laboratory energy and study
the effect of the energy dependence of the NN t-matrix. We compare this result
with experiment and with calculations where the center-of-mass energy of the NN
t-matrix is fixed at half the projectile energy. It is found that around 200
MeV the fixed energy approximation is a very good representation of the full
calculation, however deviations occur when going to lower energies (65 MeV).Comment: 11 pages (revtex), 6 postscript figure

Power tests of a string of magnets comprising a full cell of the Superconducting Super Collider
In this paper we describe the operation and testing of a string of magnets comprising a full cell of the Superconducting Super Collider (SSC). The full cell configuration composed of ten dipoles, two quadrupoles, and three spool pieces is the longest SSC magnet string ever tested. Although the tests of the full cell were undertaken after the SSC project was marked for termination, their completion was deemed necessary and useful to future efforts at other accelerator laboratories utilizing Superconducting magnets. The focus of this work is on the electrical and cryogenic performance of the string components and the quench protection system with an emphasis on solving some of the questions concerning electrical performance raised during the previous two experimental runs involving a half cell configuration
Hard X-ray emission from the Galactic ridge
We present results of a study of the Galactic ridge X-ray emission (GRXE) in
hard X-rays performed with the IBIS telescope aboard INTEGRAL. The imaging
capabilities of this coding aperture telescope make it possible to account for
the flux from bright Galactic point sources whereas the wide field of view
permits to collect large flux from the underlying GRXE. Extensive study of the
IBIS/ISGRI detector background allowed us to construct a model that predicts
the detector count rate with % accuracy in the energy band 17-60 keV.
The derived longitude and latitude profiles of the ridge emission are in good
agreement with the Galactic distribution of stars obtained from infrared
observations. This, along with the measured hard X-ray spectrum of the Galactic
ridge emission strongly indicates its stellar origin. The derived unit stellar
mass emissivity of the ridge in the energy band 17-60 keV, \lummass (assuming a bulge mass of )
agrees with that of local (in the Solar neigborhood) accreting magnetic white
dwarf binaries - dominant contributors to the GRXE at these energies. In
addition, the shape of the obtained GRXE spectrum can be used to determine the
average mass of white dwarfs in such systems in the Galaxy as \sim0.5
M_{\sun}. The total hard X-ray luminosity of the GRXE is \lum in the 17--60 keV band. At energies 70--200 keV
no additional contribution to the total emission of the Galaxy apart from the
detected point sources is seen.Comment: 13 pages, 19 figures, submitted to Astronomy and Astrophysic
