BACKGROUND The question of how many marine species exist is important because it provides a metric for how much we do and do not know about life in the oceans. We have compiled the first register of the marine species of the world and used this baseline to estimate how many more species, partitioned among all major eukaryotic groups, may be discovered.

We present an algorithm and software routines for computing nth-order Taylor series approximate solutions to dynamic, discrete-time rational expectations models around a nonstochastic steady state. The primary advantage of higher-order (as opposed to first-or second-order) approximations is that they are valid not just locally, but often globally (i.e.,(More)
Good governance-in the form of institutions that establish a predictable, impartial, and consistently enforced set of rules for investors-is crucial for the sustained and rapid growth in per capita incomes of poor countries. Aid dependence can potentially undermine institutional quality, by weakening accountability, encouraging rent seeking and corruption,(More)

We calculate the welfare cost of nominal inertia in a New Neoclassical Synthesis model with wage and price stickiness, capital formation, and empirically estimated rules for government spending and the cental bank's interest rate policy. We calibrate our model to U.S. data, and we show that it captures many aspects of the U.S. business cycle. Moreover, our(More)

BACKGROUND Increased airway smooth muscle bulk is a pathological feature of asthma. Asthma is well controlled by the combined inhalation of glucocorticoids and beta2-adrenoceptor agonists. The basic molecular mechanism of the interaction of the two drugs on proliferation of airway smooth muscle cells is yet to be identified. Our aim was to elucidate how(More)
The efficacy of two formulations of a topically applied 65% permethrin spot-on (Defend Exspot Treatment for Dogs, Schering-Plough Animal Health) was evaluated against experimental infestations of the cat flea Ctenocephalides felis and the lone star tick Amblyomma americanum in dogs. Eighteen dogs were randomly assigned to treatment with 65% permethrin in(More)
BACKGROUND Recent clinical trials investigating the role of hyperoxia in decreasing surgical site infection have reported conflicting results. Immunologic mechanisms through which supplemental oxygen could act have not been elucidated fully. The authors sought to investigate the effects of hyperoxia on previously tested and prognostically significant innate(More)
