Electronic Health Records: Cure-all or Chronic Condition?
Computer-based information systems feature in almost every aspect of our
lives, and yet most of us receive handwritten prescriptions when we visit our
doctors and rely on paper-based medical records in our healthcare. Although
electronic health record (EHR) systems have long been promoted as a
cost-effective and efficient alternative to this situation, clear-cut evidence
of their success has not been forthcoming. An examination of some of the
underlying problems that prevent EHR systems from delivering the benefits that
their proponents tout identifies four broad objectives - reducing cost,
reducing errors, improving coordination and improving adherence to standards -
and shows that they are not always met. The three possible causes for this
failure to deliver involve problems with the codification of knowledge, group
and tacit knowledge, and coordination and communication. There is, however,
reason to be optimistic that EHR systems can fulfil a healthy part, if not all,
of their potential
Business Models for e-Health: Evidence from Ten Case Studies
An increasingly aging population and spiraling healthcare costs have made the
search for financially viable healthcare models an imperative of this century.
The careful and creative application of information technology can play a
significant role in meeting that challenge. Valuable lessons can be learned
from an analysis of ten innovative telemedicine and e-health initiatives.
Having proven their effectiveness in addressing a variety of medical needs,
they have progressed beyond small-scale implementations to become an
established part of healthcare delivery systems around the world

The Materials Advantage of the SLS Selective Laser Sintering Process
The rapid prototyping market continues to progress in tenns of processes and materials
used for the creation of conceptual and functional parts and prototype tooling. As this market
continues to mature, the market leaders win be able to offer rapid prototyping processes and
materials that provide parts which are accurate, have good surface finish, and provide properties
which support fqnctional applications.. The materials used for these parts will be. polymers, metals,
and ceramics. '. The strength oithe SLSTM Selective Laser Sintering Process is the. potential to use a
wide variety of powdered materials for the creation of models, patterns, and some fonns of
prototype tooling. ,This paper will cover the types of materials currently used in the SLS process
and their inherent advantages.and discuss current research into the development of new materials.Mechanical Engineerin
Strong interactions of single atoms and photons in cavity QED
An important development in modern physics is the emerging capability for investigations of dynamical processes for open quantum systems in a regime of strong coupling for which individual quanta play a decisive role. Of particular significance in this context is research in cavity quantum electrodynamics which explores quantum dynamical processes for individual atoms strongly coupled to the electromagnetic field of a resonator. An overview of the research activities in the Quantum Optics Group at Caltech is presented with an emphasis on strong coupling in cavity QED which enables exploration of a new regime of nonlinear optics with single atoms and photons

Near-Field Emission of Lead-Sulfide-Selenide Homojunction Lasers
Measurements of the near-field intensity distributions of three lead-sulfide-selenide diode lasers operating near 4.8 μm have been made as a function of injection current. Localized emission in the near field exhibits peaked structure of full width from 5 to 10 μm for operation above threshold. From the dependence of the emission profiles on injection current estimates of 25 cm ^(-1) and 0.09 cm/A are made for the distributed loss and gain coefficients for one of the lasers. Optical confinement perpendicular to the p-n junction can be explained in terms of the homojunction properties
The future of information systems-using social systems to create protocols for the virtual environment (systems analysis through social analysis)
Information is the medium for communication, power-play, politics, and the building block for knowledge systems. It is associated with social interaction, and can be mediated by technology use. The paper argues that the key to understanding the impact of future technologies lies in the interaction between the social and technical environment. It suggests that future technologies such as virtual reality make necessary a move away from traditional methods of systems analysis and design. The interactive nature of such technology requires a validation in the social environment. The paper proposes the creation of protocols (a set of universally applicable standards) for the virtual environment. It suggests that information systems are split into three protocols: physical, learning, and cultural protocols. Finally it illustrates that their influence over each other can be understood by applying structuration theor
