The REMSDB Macroeconomic Database of The Spanish Economy
This paper presents a new macroeconomic database for the Spanish economy, REMSDB. The construction of this database has been oriented to conducting medium-term simulations for policy evaluation with the REMS model, a large Rational Expectations macroeconomic Model for Spain. The paper provides a detailed description of the data and documents its main statistical properties. The database is thought to be of major interest to related applications,whether strictly associated with the REMS model or, rather, with empirical macroeconomic studies.Spanish Data, Growth Data, Business Cycle Data, REMS
From a few to many electrons in quantum dots under strong magnetic fields: Properties of rotating electron molecules with multiple rings
Using the method of breaking of circular symmetry and of subsequent symmetry
restoration via projection techiques, we present calculations for the
ground-state energies and excitation spectra of N-electron parabolic quantum
dots in strong magnetic fields in the medium-size range 10 <= N <= 30. The
physical picture suggested by our calculations is that of finite rotating
electron molecules (REMs) comprising multiple rings, with the rings rotating
independently of each other. An analytic expression for the energetics of such
non-rigid multi-ring REMs is derived; it is applicable to arbitrary sizes given
the corresponding equilibrium configuration of classical point charges. We show
that the rotating electron molecules have a non-rigid (non-classical)
rotational inertia exhibiting simultaneous crystalline correlations and
liquid-like (non-rigidity) characteristics. This mixed phase appears in high
magnetic fields and contrasts with the picture of a classical rigid Wigner
crystal in the lowest Landau level.Comment: REVTEX4, 15 pages with 12 figures. Accepted for publication in

1 1/2 Years in Death Valley
This paper is an exploration into the historian as an independent source of history. Homer T. Rosenberger was an amateur historian in Pennsylvania during the better part of the 20th century. His works on Pennsylvania history, early American history, and contemporary historical events are valuable, if unknown, resources in those fields. However, Rosenberger becomes his own source of history when his battle with cancer is examined in the context of the American 1950\u27s. Rosenberger\u27s reactions to his plight help illustrate the mindset American brought to cancer in the 1950\u27s and the transition in American society since then
Rotorcraft-based emergency medical services in the Caribbean Basin
There is a pressing need for improved health care in general and emergency health care in particular throughout the Caribbean Basin. The importance of rotorcraft as an integral part of the needed system of emergency medical care in the region was investigated. Many of the larger countries in the region currently have the needed infrastructure to implement a national system of rotorcraft-based emergency medical centers within their borders. By helping to establish a system of rotorcraft based health care centers in strategic locations in the Lesser Antilles, the U.S. can assist the islands of the region by demonstrating the concept and establishing a potential training site for the other larger countries of the region. There is sufficient demand for rotorcraft based emergency health care within the Lesser Antilles to locate one center on the island of Puerto Rico and another one of the southern-most islands. With the use of fixed wing aircraft or long range helicopters, the two rotorcraft based centers could provide the region with rapid and efficient emergency health care. The superior speed and range of the XV-15 Tilt Rotor aircraft make it an attractive possibility for emergency transport and rescue in this region
Global financial crisis and return of South Asian Gulf migrants: patterns and determinants of their integration to local labour markets
Studies record that a large number of South Asian migrant workers in the Middle–East had to return to their home countries owing to the global financial crisis and loss of jobs. However, their distress of loss of job in the gulf is compounded by the fact that in their own home countries the rehabilitation and reintegration of these workers is tedious and often the returnees are thrust with forced choices. This paper, based on a primary survey conducted in five south Asian countries, namely; Nepal, Sri Lanka, Bangladesh, Pakistan and India, concludes that on return, the employment status of REMs were in general worse off than in their host country with high share of casualisation, self employment and unemployment in the crisis year and a decline in their average monthly earnings. The analysis suggests that those who found employment on return was in fact driven by economic compulsions to reduce their job search period and cost.Global Financial Crisis; Return Migrants; South Asia; Employment; Wages
Evidence and Extrapolation: Mechanisms for Regulating Off-Label Uses of Drugs and Devices
A recurring, foundational issue for evidence-based regulation is deciding whether to extend governmental approval from an existing use with sufficient current evidence of safety and efficacy to a novel use for which such evidence is currently lacking. This extrapolation issue arises in the medicines context when an approved drug or device that is already being marketed is being considered (1) for new conditions (such as off-label diagnostic categories), (2) for new patients (such as new subpopulations), (3) for new dosages or durations, or (4) as the basis for approving a related drug or device (such as a generic or biosimilar drug). Although the logic of preapproval testing and the precautionary principle—first, do no harm—would counsel in favor of prohibiting extrapolation approvals until after traditional safety and efficacy evidence exists, such delays would unreasonably sacrifice beneficial uses. The harm of accessing unsafe products must be balanced against the harm of restricting access to effective products. In fact, the Food and Drug Administration\u27s (FDA\u27s) current regulations in many ways reject the precautionary principle because they largely permit individual physicians to prescribe medications for off-label uses before any testing tailored to those uses has been done. The FDA\u27s approach empowers physicians, but overshoots the mark by allowing enduring use of drugs and devices with insubstantial support of safety and efficacy. This Article instead proposes a more dynamic and evolving evidence-based regime that charts a course between the Scylla and Charybdis of the overly conservative precautionary principle on one hand, and the overly liberal FDA regime on the other.
Our approach calls for improvements in reporting, testing, and enforcement regulations to provide a more layered and nuanced system of regulatory incentives. First, we propose a more thoroughgoing reporting of off-label use (via the disclosure of diagnostic codes and detailing data) in manufacturers\u27 annual reports to the FDA, in the adverse event reports to the FDA, in Medicare/Medicaid reimbursement requests, and, for a subset of FDA-designated drugs, in prescriptions themselves. Second, we would substantially expand the agency\u27s utilization of postmarket testing, and we provide a novel framework for evaluating the need for postmarket testing. Finally, our approach calls for a tiered labeling system that would allow regulators and courts to draw finer reimbursement and liability distinctions among various drug uses, and would provide the agency both the regulatory teeth and the flexibility it presently lacks. Together, these reforms would improve the role of the FDA in the informational marketplace underlying physicians\u27 prescribing decisions. This evolutionary extrapolation framework could also be applied to other contexts
