We investigate the effects of fiscal policy surprises for US data, using vector autoregressions. We overcome the difficulties that changes in fiscal policy may manifest themselves in variables other than fiscal variables first and that fiscal variables may respond ”automatically” to business cycle conditions. We do so by using sign restrictions on the impulse responses as method of identificati...

Using data from charitable organizations in the US, authors have established that government grants to charities largely crowd out giving from other sources, but that this reduction is due mostly to reduced fundraising activities of the charity itself. We use much more detailed data from over 6000 charities in Canada, measured for up to 15 years, to provide valuable new insights into this pheno...

A relatively new entrant to the class of high energy materials, viz., 1,3,5-trinitro-5-methyl-hexahydropyrimidine (MTNP) has been synthesized during this work by nitration of 1,3-di-tert-butyl-5-nitro-5-methyl hexahydropyrimidine with fuming nitric acid. The synthesized molecule (MTNP) has been characterized by elemental analysis, IR, H and C NMR spectroscopy. TG of the compound showed two-step...

The issue of whether the public sector enhances or retards long-run economic growth has been debated passionately in recent years. We use meta-analysis to shed light on the issue. A sample of 93 published studies, yielding 123 meta-observations, is used to examine the robustness of the evidence regarding the impact of fiscal policy on growth. Five fiscal policy areas are considered: general gov...

A highly specific Diels-Alder protein catalyst was made by manipulating the antibody repertoire of the immune system. The catalytic antibody 13G5 catalyzes a disfavored exo Diels-Alder transformation in a reaction for which there is no natural enzyme counterpart and that yields a single regioisomer in high enantiomeric excess. The crystal structure of the antibody Fab in complex with a ferrocen...

This paper argues that currently advanced, aging economies experienced a qualitative change in the role of public education during the process of industrialization. In the early phases of the Industrial Revolution, public education was regarded as a duty that regulated child labor and thereby discouraged childbirth. As these economies developed and the population aged, younger generations came ...

Isolated sugarcane (Saccharum spp. hybrid H50-7209) vacuoles incorporate radioactivity during incubation with labeled UDP-glucose by a mechanism which was postulated to be responsible for sucrose storage in the vacuoles (UDP-glucose group translocator). Analysis of the reaction products in the medium revealed that several enzymic processes are going on during incubation with UDP-glucose such as...

Hulme, J. T., and C. H. Orchard Effect of acidosis on transient outward potassium current in isolated rat ventricular myocytes. Am. J. Physiol. Heart Circ. Physiol. 278: H50–H59, 2000.—The effect of acidosis on the transient outward K1 current (Ito) of rat ventricular myocytes has been investigated using the perforated patch-clamp technique. When the holding potential was 280 mV, depolarizing p...

Stumpe, Thomas, and Jürgen Schrader. Short-term hibernation in adult cardiomyocytes is PO2 dependent and Ca mediated. Am J Physiol Heart Circ Physiol 280: H42–H50, 2001.—The mechanism of myocardial hibernation, the reversible downregulation of contractile activity on reduction of coronary flow with unchanged cardiac energetics, is presently not understood. The oxygen consumption (V̇O2), shorteni...

The virialization shock around an X-ray cluster primarily heats the ions, since they carry most of the kinetic energy of the infalling gas. Subsequently, the ions share their thermal energy with the electrons through Coulomb collisions. We quantify the expected temperature difference between the electrons and ions as a function of radius and time, based on a spherical self-similar model for the...
