text: "We study how competition between physicians affects the provision of medical
care. In\r\nour theoretical model, physicians are faced with a heterogeneous patient
population, in which patients\r\nsystematically vary with regard to both their
responsiveness to the provided quality of care and their\r\nstate of health. We
test the behavioral predictions derived from this model in a controlled laboratory\r\nexperiment.
In line with the model, we observe that competition significantly improves patient
benefits\r\nas long as patients are able to respond to the quality provided. For
those patients, who are not able\r\nto choose a physician, competition even decreases
the patient benefit compared to a situation without\r\ncompetition. This decrease
is in contrast to our theoretical prediction implying no change in benefits for\r\npassive
patients. Deviations from patient-optimal treatment are highest for passive patients
in need of\r\na low quantity of medical services. With repetition, both, the positive
effects of competition for active\r\npatients as well as the negative effects
of competition for passive patients become more pronounced. Our\r\nresults imply
that competition can not only improve but also worsen patient outcome and that
patients’\r\nresponsiveness to quality is decisive."

text: In this publication, further elements of the newly developed inductive localization
in the near field are presented. The advantage of inductive localization is the
usage of the magnetic fields, which have a very low influence of non-metallic
materials in the environment and thus follows good applications in the area of
medicine and biochemistry. This allows a precise localization of sensor platforms
in inhomogeneous mixtures of materials, where classical methods have major problems
with inhomogeneous dielectric conductivity or density. The calculation of the
localization of the searched object differs from other methods such as ultrasound
or electromagnetic waves due to the source-free propagation of the magnetic field.
Therefore, new mathematical evaluation methods and systematic adaptations are
necessary, which are presented in this paper in circuit analysis. For this purpose,
the exact circuit influences of one coil and the influence of another coil are
investigated and which resonance circuit should be selected for both coils for
a inductive localization with optimized signal strength.

text: Piezoelectric inertia motors use the inertia of a body to drive it by means
of a friction contact in a series of small steps. These motors can operate in
``stick-slip'' or ``slip-slip'' mode, with the fundamental frequency of the driving
signal ranging from several Hertz to more than 100 kHz. To predict the motor characteristics,
a Coulomb friction model is sufficient in many cases, but numerical simulation
requires microscopic time steps. This contribution proposes a much faster simulation
technique using one evaluation per period of the excitation signal. The proposed
technique produces results very close to those of timestep simulation for ultrasonics
inertia motors and allows direct determination of the steady-state velocity of
an inertia motor from the motion profile of the driving part. Thus it is a useful
simulation technique which can be applied in both analysis and design of inertia
motors, especially for parameter studies and optimisation.

text: Employing data on foreign bank claims from 13 OECD countries on 51 emerging
markets between 1993 and 2007, this study investigates specific characteristics
of OECD banking markets and lending banks as new important determinants of cross-border
lending. We initially provide empirical evidence that in addition to well-accepted
“gravity measures”, characteristics of OECD banking markets as well as lending
banks’ attributes may describe further important determinants of cross-border
bank lending with regard to our sample. Building subsamples of more-developed
emerging markets vs. frontier markets, addressing (non) common lender relationships
and analyzing cross border lending flows during different time periods, our analysis
additionally reveals that both the determinants’ explanatory power and their direction
of impact notably vary with respective subsamples.

text: 'Several positioning tasks demand translatory drive instead of rotary motion.
To achieve drives that are capable, e.g., to drive the sunroof of a car or to
lift a car''s window, multiple miniaturized motors can be combined. But in this
case many other questions arise: The electromechanical behavior of the individual
motors differs slightly, the motor characteristics are strongly dependent on the
driving parameters and the driven load, many applications need some extra power
for special cases like overcoming higher forces periodically. Thus, the bundle
of motors has to act well-organized and at last controlled to get an optimized
drive that is not oversized and costly.'
