Can Foreign Health Assistance Reduce the Medical Brain Drain?

This paper analyses the impact of foreign health aid on the emigration rates of physicians. We use a panel database to investigate the emigration of physicians from 192 source countries to 17 destination countries between 1995 and 2004. First, we investigate the direct impact of health assistance using the generalised method of moments (GMM) and highlight a significant negative effect of foreign health assistance on the medical brain drain. Moreover, we analyse whether this effect of health aid is more effective in a context of good governance. We find that health aid is more effective at reducing physicians' emigration rates when the levels of corruption and inflation are low.International Migration, Physicians Emigration Rates, Foreign Aid, Foreign health assistance

Can Health Foreign Assistance Break the Medical Brain Drain ?

This paper analyse the impact of health foreign assistance on physicians' brain drain. We use the database from Bhargava and Docquier (2008) to explain physicians' brain drain and health foreign assistance from 1995 to 2003 using a bilateral gravity equation model. In the first time, we propose to investigate the direct and reverse impact of health assistance through simultaneous equation model with Three-Stage Least Squares (3SLS) methodology and highlight a significant negative effect of health foreign assistance on the medical brain whereas emigration rate of doctor increases the amount of health aid received by recipient countries. In a second time, we analyzed the indirect effect of health aid via epidemics prevalence through the death rate per 1000 people. We find that health aid plays a key role in the improvement of vaccination, treatment and prevention which may reduce death rate and, finally, decreases the physicians emigration rates. These findings confirm the efficiency of health foreign aid to weaken the vicious circle of physicians drain.International migration ; physicians emigration rates ; foreign aid ; health foreign assistance ; simultaneous equation model ; Three Stage Least Squares ; gravity equation model

Disappearance of Spurious States in Analog Associative Memories

We show that symmetric n-mixture states, when they exist, are almost never stable in autoassociative networks with threshold-linear units. Only with a binary coding scheme we could find a limited region of the parameter space in which either 2-mixtures or 3-mixtures are stable attractors of the dynamics.Comment: 5 pages, 3 figures, accepted for publication in Phys Rev

Measurement-Assisted Quantum Communication in Spin Channels with Dephasing

We propose a protocol for countering the effects of dephasing in quantum state transfer over a noisy spin channel weakly coupled to the sender and receiver qubits. Our protocol, based on performing regular global measurements on the channel, significantly suppresses the nocuous environmental effects and offers much higher fidelities than the traditional no-measurement approach. Our proposal can also operate as a robust two-qubit entangling gate over distant spins. Our scheme counters any source of dephasing, including those for which the well established dynamical decoupling approach fails. Our protocol is probabilistic, given the intrinsic randomness in quantum measurements, but its success probability can be maximized by adequately tuning the rate of the measurements.Comment: 8 pages, 9 figure
