This study examined differences in learning outcomes among newborn intensive care unit (NICU) workers who underwent virtual reality simulation (VRS) emergency evacuation training versus those who received web-based clinical updates (CU). Learning outcomes included a) knowledge gained, b) confidence with evacuation, and c) performance in a live evacuation exercise.
A longitudinal, mixed-method, quasi-experimental design was implemented utilizing a sample of NICU workers randomly assigned to VRS training or CUs. Four VRS scenarios were created that augmented neonate evacuation training materials. Learning was measured using cognitive assessments, self-efficacy questionnaire (baseline, 0, 4, 8, 12 months), and performance in a live drill (baseline, 12 months). Data were collected following training and analyzed using mixed model analysis. Focus groups captured VRS participant experiences.
The VRS and CU groups did not statistically differ based upon the scores on the Cognitive Assessment or perceived self-efficacy. The virtual reality group performance in the live exercise was statistically (P<.0001) and clinically (effect size of 1.71) better than that of the CU group.
Training using VRS is effective in promoting positive performance outcomes and should be included as a method for disaster training. VRS can allow an organization to train, test, and identify gaps in current emergency operation plans. In the unique case of disasters, which are low-volume and high-risk events, the participant can have access to an environment without endangering themselves or clients.

This paper employs the state-space model to reexamine the fundamental issue in finance of whether it is the expected returns or the expected dividends growth that is primarily responsible for stock price variations. We use Bayesian methods to show that there is a substantial uncertainty about the contributions of expected returns and expected dividends to fluctuations in the price–dividend ratio when the aggregate returns and dividends data are used. The substantial uncertainty of the contributions results from the model being weakly identified. Our finding challenges the notion long held in the existing literature that it is the expected returns that contribute most to price–dividend variations.
Wireless power transfer is experimentally demonstrated by transmission between an AC power transmitter and receiver, both realised using thin film technology. The transmitter and receiver thin film coils are chosen to be identical in order to promote resonant coupling. Planar spiral coils are used because of the ease of fabrication and to reduce the metal layer thickness. The energy transfer efficiency as a function of transfer distance is analysed along with a comparison between the theoretical and the experimental results.
This chapter is concerned with two distinct but related questions: (a) does Deleuzian philosophy offer an account of moral norms (i.e., a theory of normativity)? (b) does Deleuzian philosophy offer an account of moral values (i.e., a theory of the good)? These are important questions for at least two reasons. First, the moral- and value-theoretical aspects of Deleuzian philosophy have tended to be ignored, dismissed, overlooked, or otherwise overshadowed in the literature by the ontological, historical, and political aspects. Second, Deleuze – along with other alleged “postmodernists” such as Foucault and Derrida – has occasionally been accused of moral relativism, skepticism, and even nihilism. The aim of what follows is to demonstrate the value and importance of Deleuze's (and Guattari's) contributions to ethics and to defend Deleuzian philosophy from the charges just mentioned.
Between 1933 and 1945, Nazi Germany systematically dismantled German democracy, violated international law, and perpetrated countless horrific crimes against humanity – chief among them the extermination of 11 million people, approximately 6 million of whom were Jews. Between 1948 and 1994, Nelson Mandela and other activists engaged in a bloody but ultimately successful battle against the racist government of South Africa in an effort to abolish apartheid. Most people would regard the actions of the Nazis as morally reprehensible and the actions of the anti-apartheid freedom fighters as morally praiseworthy.
Deleuze is perhaps best known for his influential works in philosophical interpretation; epistemology; metaphysics; and political economy. The essays in this collection explore uncover and trace the ethical dimension of Deleuzian philosophy along diverse trajectories and in so doing endeavour to reclaim that philosophy as moral philosophy.
It is customary to introduce a book of this sort by offering a brief overview of its essays and articles. I hope the reader will forgive me for straying from this convention – conventions being, after all, somewhat beside the point in a book about Deleuze. (A quick glance at each chapter's opening will prove sufficient to glean its gist and will hopefully serve to pique your interest as well.) Instead, I want to provide an introduction which is, one might say, apologetic rather than synoptic. Specifically, I want to stumble in the general direction of explaining why I think this volume is relevant, timely, and at least marginally important. Why Deleuze? Why ethics? Why now, and why ought we to care?
Ten years into the Deleuzian century, and fifteen since la mort de la même, few would disagree that the world as we know it is sinking into an economic, political, social, and ethical abyss of previously unimaginable depths. Back in the halcyon days when that world was still in its infancy, Deleuze was widely heralded as a visionary who would help us demystify the web of global technological and financial networks which was, at that time, just starting to be spun. Since then, the prophecies have largely come to pass; everyone from Žižek to Badiou is fond of saying that the conceptual and methodological tools with which we make sense of this age are Deleuzian tools.
We have investigated temperature dependence on the hysteresis phenomenon of SLS poly-Si TFT on a glass substrate, extremely at low temperature (213K). The p-type sequential lataral solidification (SLS) polycrystalline Silicon (poly-Si) TFT was fabricated on glass substrate. As the temperature was reduced, it was observed that hysteresis phenomenon was increased, whereas the hysteresis was suppressed at high temperature. This could be explained by a difference of initially electron and hole trapped charges into gate insulator is much larger in low temperature than in high temperature. And we have verified that drain current was changed with a different previous gate starting voltage even at same bias condition by experimental results due to the hysteresis phenomenon of SLS poly-Si TFT. Hysteresis of SLS poly-Si TFT should be improved for a pixel element of high quality AMOLED display.
Surface passivation of silicon substrates using atomic layer deposited Al2O3 and HfO2 thin films are assessed. Al2O3 and HfO2 dielectric layers with various thicknesses were deposited on both sides of n-type (100) FZ-Si substrates (resistivity 4 – 6 Ω-cm) at 200°C by atomic layer deposition (ALD) system. The effective excess carrier lifetime of as-deposited oxide/Si/oxide structure was measured by microwave-photoconductivity-decay (MWPCD) measurement technique and it was observed that the thicker ALD dielectrics lead to higher effective excess carrier lifetime and better surface passivation. The measurements showed average excess carrier lifetime values of 302 μs and 347 μs for as-deposited Al2O3 and HfO2 passivated Si substrates with 150 ALD cycles, respectively. MWPCD and capacitance-voltage (C-V) measurements suggest that as-deposited ALD HfO2 layer leads to a better surface passivation compared to as-deposited ALD Al2O3 layer. Further, the results suggest that there exist fixed negative charges in the bulk of the ALD dielectrics and this contributes to the field effect passivation of the silicon surfaces.
Improved accuracy in measurement of the gravitational time delay of electromagnetic waves passing by the sun may be achieved with two drag-free spacecraft, one with a stable clock and laser transmitter and one with a high-stability transponder. We consider one spacecraft near the Earth-Sun L1 point with an advanced optical clock, and the transponder on a second satellite, which has a 2 year period orbit and eccentricity e = 0.37. Superior conjunctions will occur at aphelion 1, 3, and 5 years after launch of the second spacecraft. The measurements can be made using carrier phase comparisons on the laser beam that would be sent to the distant spacecraft and then transponded back. Recent development of clocks based on optical transitions in cooled and trapped ions or atoms indicate that a noise spectral amplitude of about 5 × 10−15/ at frequencies down to at least 1 microhertz can be achieved in space-borne clocks. An attractive candidate is a clock based on a single laser-cooled Yb+ trapped ion. Both spacecraft can be drag-free at a level of 1×10−13m/s2/ at frequencies down to at least 1 microhertz. The corresponding requirement for the LISA gravitational wave mission is 3 × 10−15m/s2/ at frequencies down to 10−4 Hz, and Gravitational Reference Sensors have been developed to meet this goal. They will be tested in the LISA Pathfinder mission, planned by ESA for flight in 2011. The requirements to extend the performance to longer times are mainly thermal. The achievable accuracy for determining the PPN parameter γ is about 1 × 10−8.
