Management von Reputationsrisiken in Banken
Die Reputation einer Bank ist von grosser Bedeutung für die Sicherung einer nachhaltigen Rentabilität. Sie wird definiert als der aus Wahrnehmungen der Anspruchsgruppen resultierende öffentliche Ruf einer Bank bezüglich ihrer Kompetenz, Integrität und Vertrauenswürdigkeit. Reputationsrisiken bestehen in der Gefahr einer negativen und der Chance einer positiven Abweichung der Reputation einer Bank vom erwarteten Niveau. Zur Abgrenzung von anderen Risikokategorien können Reputationsrisiken auch als reputationswirksamer Teil der operationellen und der Finanzrisiken bezeichnet werden. Schlagend werdende Reputationsrisiken wirken sich über Handlungen und Reaktionen der Anspruchsgruppen zum Vor- oder Nachteil der Bank aus und führen entsprechend zu Marktwertgewinnen oder -verlusten. Die damit verbundenen Kosten- und Erlöswirkungen sind ex ante nicht quantifizierbar. Dem aktiven Reputationsmanagement kommt die Aufgabe zu, Reputationsrisiken in einem gezielten Prozess zu definieren, zu identifizieren, zu messen und zu steuern ..
Clinical radiography education across Europe
Purpose: To establish a picture of clinical education models within radiography programmes across Europe by surveying higher education institutions registered as affiliate members of the European Federation of Radiography Societies (EFRS).
Method: An online survey was developed to ascertain data on: practical training, supervisory arrangements, placement logistics, quality assurance processes, and the assessment of clinical competencies. Responses were identifiable in terms of educational institution and country. All educational institutions who were affiliate members at the time of the study were invited to participate (n=46). Descriptive and thematic analyses are reported.
Results: A response rate of 82.6% (n=38) was achieved from educational institutions representing 21 countries. Over half of responding institutions (n=21) allocated in excess of 60 European Credit Transfer and Accumulation System (ECTS) credits to practical training. In nearly three-quarters of clinical placements there was a dedicated clinical practice supervisor in place; two-thirds of these were employed directly by the hospital. Clinical practice supervisors were typically state registered radiographers, who had a number of years of clinical experience and had received specific training for the role. Typical responsibilities included monitoring student progress, providing feedback and completing paperwork, this did however vary between respondents. In almost all institutions there were support systems in place for clinical placement supervisors within their roles.
Conclusions: Similarities exist in the provision of clinical radiography education across Europe. Clinical placements are a core component of radiography education and are supported by experienced clinical practice supervisors. Mechanisms are in place for the selection, training and support of clinical practice supervisors. Professional societies should work collaboratively to establish guidelines for effective clinical placements

Neutral Pions with Large Transverse Momentum in d+Au and Au+Au Collisions
Measurements of transverse-momentum p_T spectra of neutral pions in Au+Au and
d+Au collisions at sqrt{s_NN}=200 GeV and 62.4 GeV by the PHENIX experiment at
RHIC in comparison to p+p reference spectra at the same sqrt{s_NN} are
presented. In central Au+Au collisions at sqrt{s_NN}=200 GeV a factor 4-5
suppression for neutral pions and charged hadrons with p_T > 5 GeV/c is found
relative to the p+p reference scaled by the nuclear overlap function .
In contrast, such a suppression of high-p_T particles is absent in d+Au
collisions independent of the centrality of the collision. To study the
sqrt{s_NN} dependence of the suppression Au+Au collisions at sqrt{s_NN}=200 GeV
and 62.4 GeV are compared.Comment: 7 pages, 5 figures, presented at Hot Quarks 2004, Taos, N
Matching Regge Theory to the OPE
The spectra of masses and decay constants for non-strange meson resonances in
the energy range 0--2.5 GeV is analyzed. It is known from meson phenomenology
that for given quantum numbers these spectra approximately follow linear
trajectories with a universal slope. These facts can be understood in terms of
an effective string description for QCD. For light meson states the
trajectories deviate noticeably from the linear behavior. We investigate the
possible corrections to the linear trajectories by matching two-point
correlators of quark currents to the Operator Product Expansion (OPE). We find
that the allowed modifications to the linear Regge behavior must decrease
rapidly with the principal quantum number. After fitting the lightest states in
each channel and certain low-energy constants the whole spectrum for meson
masses and residues is obtained in a satisfactory agreement with phenomenology.
We briefly speculate on possible implications for the QCD effective string.Comment: 24 pages, Latex, significant changes in discussion of fits, more refs

High resolution spatial modelling of greenhouse gas emissions from land use change to energy crops in the UK
We implemented a spatial application of a previously evaluated model of soil GHG emissions, ECOSSE, in the United Kingdom to examine the impacts to 2050 of land-use transitions from existing land use, rotational cropland, permanent grassland or woodland, to six bioenergy crops; three ‘first-generation’ energy crops: oilseed rape, wheat and sugar beet, and three ‘second-generation’ energy crops: Miscanthus, short rotation coppice willow (SRC) and short rotation forestry poplar (SRF). Conversion of rotational crops to Miscanthus, SRC and SRF and conversion of permanent grass to SRF show beneficial changes in soil GHG balance over a significant area. Conversion of permanent grass to Miscanthus, permanent grass to SRF and forest to SRF shows detrimental changes in soil GHG balance over a significant area. Conversion of permanent grass to wheat, oilseed rape, sugar beet and SRC and all conversions from forest show large detrimental changes in soil GHG balance over most of the United Kingdom, largely due to moving from uncultivated soil to regular cultivation. Differences in net GHG emissions between climate scenarios to 2050 were not significant. Overall, SRF offers the greatest beneficial impact on soil GHG balance. These results provide one criterion for selection of bioenergy crops and do not consider GHG emission increases/decreases resulting from displaced food production, bio-physical factors (e.g. the energy density of the crop) and socio-economic factors (e.g. expenditure on harvesting equipment). Given that the soil GHG balance is dominated by change in soil organic carbon (SOC) with the difference among Miscanthus, SRC and SRF largely determined by yield, a target for management of perennial energy crops is to achieve the best possible yield using the most appropriate energy crop and cultivar for the local situation
Photon-assisted tunneling in a Fe8 Single-Molecule Magnet
The low temperature spin dynamics of a Fe8 Single-Molecule Magnet was studied
under circularly polarized electromagnetic radiation allowing us to establish
clearly photon-assisted tunneling. This effect, while linear at low power,
becomes highly non-linear above a relatively low power threshold. This
non-linearity is attributed to the nature of the coupling of the sample to the
thermostat.These results are of great importance if such systems are to be used
as quantum computers.Comment: 4 pages, 4 figure
