Healthcare Information Technology Adoption and Protection Motivation: A Study of Computerized Physicial Order Entry Systems

In this study, considering medical errors causing significant patient safety risk as the major threat perceived by health care providers, we adopt the protection motivation theory (PMT) from health psychology and investigate factors affecting the decision of health care providers to adopt CPOE systems. This research examines the effect of two major PMT variables on the CPOE adoption such as threat appraisal variables (i.e. perceived severity and vulnerability of threat, rewards) and cognitive appraisal variables (i.e. response efficacy, self-efficacy, and response cost). In addition, this study extends the original PMT model by incorporating the internal organizational and environmental factors associated with CPOE systems adoption and examine their effects on its actual adoption. They are organizational size, IT resources, top management support, industry and government regulations, and competitive pressures. A semistructured interview with senior executives at five regional healthcare providers was conducted and a national questionnaire-based field survey with senior healthcare executives will be followed for this research. The potential theoretical and practical implications are discussed

Materials for Biomedical Applications

This paper discusses two ceramic material systems for selective laser sintering (SLS) that are being developed for biomedical applications for use in repair of bone defects. SLS is the preferred method of fabricating ceramic implants that exhibit well defined porous microstructures. Implants fabricated in this. manner have proven effective in-vivo showing excellent biocompatibility as well as considerable osseous integration and remodeling of the imp'ant materialMechanical Engineerin

Location Independent Working In Academia: Enabling employees or supporting managerial control?

In this article, we consider the extent to which the practice of location independent working (LIW) enables academic employees to make choices and have agency in their life-work balance, and the extent to which it may support (or potentially be used as a form of resistance to) increased managerial control. Set within the context of an increasingly performance-led, managerialist public sector landscape, the impact and implications of these working practices are examined through the lens of labour process theory. Drawing on findings from an ongoing in-depth ethnographic study set in a post-1992 university business school in central England, we suggest that the practice of LIW is being used both to enable employees and to support managerial control

Ferromagnetic/III-V semiconductor heterostructures and magneto-electronic devices

The interface magnetic and electronic properties of two Fe/III-V semiconductor systems, namely Fe/GaAs and Fe/InAs, grown at room temperature have been studied. A "magnetic interface", which is essential for the fabrication of magneto-electronic (ME) devices, was realized in both Fe/GaAs and Fe/InAs systems with suitable substrate processing and growth conditions. Furthermore, Fe/InAs was shown to have favorable interface electronic properties as Fe forms a low resistance ohmic contact on InAs. Two prototypes of ME device based on Fe/InAs are also discussed

The Online Waiting Experience: Using Temporal Information and Distractors to Make Online Waits Feel Shorter

Research on how to manage the online waiting experience has begun to emerge but has primarily focused on the use of distracting cues for online wait management (e.g., text and images that distract the user from the wait). The use of temporal information in waiting webpages (e.g., text and images that convey the duration of the wait) has received little attention from the information systems literature, and we have limited understanding about how the two types of cues (temporal information and distractors) affect wait time estimation. We address this gap by developing a theoretical model of how these cues affect the waiting experience and perceived waiting time. We tested the model with a 2 x 2 x 2 x 2 controlled lab experiment and 1025 participants using progress bar treatments that included temporal information (spatial and text description of the wait time duration) and distractors (progress bar animation and accelerated filling of the progress bar) with both short and long wait conditions. We found that the two types of cues reduced perceived waiting time through different nomological paths. Temporal cues reduced perceived uncertainty about the wait, while distractor cues directed attention away from the wait, increasing perceived enjoyment and wait time distortion. Further, the enhanced waiting experience reduced the perceived waiting time. Further, these cues were effective in managing the online waiting experience with both short and long waits

Low-frequency variability in the Florida Current and relations to atmospheric forcing from 1972 to 1974

Two-year records of temperature and current from a single subsurface mooring are demonstrated to be representative of the fluctuation spectrum of the Florida Current for time scales of several days to one or more years. The dominant subinertial motions occur in three period bands: from 8 to 25 days, 4 to 5 days, and 2 to 3 days. Simultaneous observations in a crossstream array reveal energy maxima in the same bands for all locations...

High-energy expansion of Coulomb corrections to the e+e- photoproduction cross section

First correction to the high-energy asymptotics of the total $e^+e^-$ photoproduction cross section in the electric field of a heavy atom is derived with the exact account of this field. The consideration is based on the use of the quasiclassical electron Green function in an external electric field. The next-to-leading correction to the cross section is discussed. The influence of screening on the Coulomb corrections is examined in the leading approximation. It turns out that the high-energy asymptotics of the corresponding correction is independent of the photon energy. In the region where both produced particles are relativistic, the corrections to the high-energy asymptotics of the electron (positron) spectrum are derived. Our results for the total cross section are in good agreement with experimental data for photon energies down to a few $MeV$. In addition, the corrections to the bremsstrahlung spectrum are obtained from the corresponding results for pair production.Comment: 22 pages, 7 figures, RevTeX.Typos are corrected. The numerical results, figures and conclusions remain unchanged as they were obtained using correct formula

The Liquid-Gas Phase Transitions in a Multicomponent Nuclear System with Coulomb and Surface Effects

The liquid-gas phase transition is studied in a multi-component nuclear system using a local Skyrme interaction with Coulomb and surface effects. Some features are qualitatively the same as the results of Muller and Serot which uses relativistic mean field without Coulomb and surface effects. Surface tension brings the coexistance binodal surface to lower pressure. The Coulomb interaction makes the binodal surface smaller and cause another pair of binodal points at low pressure and large proton fraction with less protons in liquid phase and more protons in gas phase.Comment: 20 pages including 7 postscript figure

EYM equations in the presence of q-stars

We study Einstein-Yang-Mills equations in the presence of gravitating non-topological soliton field configurations, of q-ball type. We produce numerical solutions, stable with respect to gravitational collapse and to fission into free particles, and we study the effect of the field strength and the eigen-frequency to the soliton parameters. We also investigate the formation of such soliton stars when the spacetime is asymptotically anti de Sitter.Comment: 11 pages, to appear in Phys. Rev.
