The paper considers the local provision of public infrastructure when population is mobile. It shows that inflexible deficit limitation may result in too little local public investment if population is perfectly mobile in the long run. Conversely, given the existence of migration externalities, implementing Musgrave's pay as you use finance, according to which new debt should match net investme...

Aim: To monitor the training intensity distribution (TID) and the development of physiological and performance parameters. Methods: During their preparation period for the RAAM, 4 athletes (plus 1 additional backup racer) performed 3 testing sessions; one before, one after 3, and one after 6 months of training. VO2max, maximal rate of lactate accumulation (dLa/dtmax), critical power, power outp...

At present, there is no dedicated software platform for the coastal zone remote sensing information extraction. For the complexity of the coastal zone targets which contains shoreline, vegetation and coastal zone types and so on, users can not extract information automatically by computers, so users need operate extraction by comparing to interpreting marks and remote sense images frequently. I...

editorial editorial l ong ago, in a political galaxy far away, i was educated at one of the world's elite universities. neither i, nor my middle-class parents, paid a penny in upfront fees for this privilege. in fact, the state—or more precisely my local municipality—paid me a substantial 'maintenance grant' every term which covered my room in college, living expenses, books and other study ess...

We examine the generation of gravity waves by the surface convection zone of low-mass main sequence stars with solar metallicity. It is found that the total momentum luminosity in waves rises with stellar mass, up to the quasi-disappearance of the convection zone around 6500 K (corresponding to a mass of ∼1.4 M⊙ for solar metallicity) where the luminosity drastically drops. We calculate the net...

Many of the world's northern peatlands are underlain by rapidly thawing permafrost. Because plant production in these peatlands is often nitrogen (N)-limited, a release of N stored in permafrost may stimulate net primary production or change species composition if it is plant-available. In this study, we aimed to quantify plant-available N in thawing permafrost soils of subarctic peatlands. We ...

The gel phase of bovine nasal secretion was separated from the liquid phase and exposed to parainfluenza-3 virus or Vibrio cholerae neuraminidase under optimal in vitro conditions. N-Acetylneuraminic acid was released from the gel by either neuraminidase. The release of N-acetylneuraminic acid was accompanied by a decrease in the net negative charge of the gel, as evidenced by free zone electro...

This study exploits the introduction of the London Congestion Charge (CC) that greatly improves traffic conditions in Central London to provide new evidence on the capitalization of traffic externalities onto housing values. The Congestion Charge restricts traffic into the cordoned area by imposing a flat fee on drivers whenever they enter during charging periods. I show that the introduction o...
