Nebular emission from star-forming galaxies
We present a new model for computing consistently the line and continuum\nemission from galaxies, based on a combination of recent population synthesis\nand photoionization code...
The ROSAT Brightest Cluster Sample -- III. Optical spectra of the central cluster galaxies
We present new spectra of dominant galaxies in X-ray selected clusters, which combine with our previously published spectra to form a sample of 256 dominant galaxies in 215 clus...
Hunting income patterns among the Hadza: big game, common goods, foraging goals and the evolution of the human diet
The assumption that large mamm al hunting and scavenging are economically advantageous to hominid foragers is examined in the light of data collected among the Hadza of northern...
Motor practice and neurophysiological adaptation in the cerebellum: a positron tomography study
We have used positron tomography (PET) to demonstrate that some parts of the motor system exhibit physiological adaptation during the repeated performance of a simple motor task...
Astronomical calibration of Oligocene--Miocene time
Lithological cyclicity was observed aboard the JOIDES RESOLUTION in sediment sequences recovered from the Ceara Rise during ODP Leg 154. Shipboard work led to the conclusion tha...
Causal Variables, Indicator Variables and Measurement Scales: An Example from Quality of Life
Summary There is extensive literature on the development and validation of multi-item measurement scales. Much of this is based on principles derived from psychometric theory an...
The Elements of Integration and Lebesgue Measure.
THE ELEMENTS OF INTEGRATION. Measurable Functions. Measures. The Integral. Integrable Functions. The Lebesgue Spaces L p . Modes of Convergence. Decomposition of Measures. Gener...
Temporal analysis of archived samples indicates marked genetic changes in declining North Sea cod (<i>Gadus morhua</i>)
Despite increasing evidence that current exploitation rates can contribute to shifts in life-history traits and the collapse of marine fish stocks, few empirical studies have in...
Confidence Sets for the Mean of a Multivariate Normal Distribution
SUMMARY An attempt is made to determine confidence sets for the mean of a multivariate normal distribution with known covariance matrix that take advantage of the fact that the ...
