The scientific referee
Frank T. Manheim
1975, IEEE Transactions on Professional Communication (PC-18) 190-195
In the May 1973 issue of EOS, I criticized tendencies in earth science periodicals to discourage referee anonymity. I stressed that exposing referees to unnecessary personal and subjective influences tended to degrade standards of quality and promoted cliques, fragmentation, superspecialization, and proliferation of scientific literature. Generally speaking, division of opinion...

R. A. Gulbrandsen
1975, Journal of Research of the U.S. Geological Survey (3) 409-414
Whitlockite and apatite are the principal phosphate minerals in the surficial deposits of Enderbury Island; monetite and brushite are present in small amounts. All are derived from the guano of sea birds. The abundance of whitlockite discovered on Enderbury, and reported in samples from Remire Island in the Indian Ocean,...
Morphology and phylogeny of the coccolithophycean family Ceratolithaceae
Stefan Gartner, David Bukry
1975, Journal of Research of the U.S. Geological Survey (3) 451-465
The family Ceratolithaceae includes a group of horseshoe-shaped calcareous nannofossils and contains ten species which are assignable to two genera: Amaurolithus n. gen. and Ceratolithus. Species of Amaurolithus are characterized by showing faint or no birefringence in cross-polarized light when viewed in preferred orientation. Included in Amaurolithus are A. amplificus...
Computer-generated shaded-relief images
R. M. Batson, Kathleen Edwards, E. M. Eliason
1975, Journal of Research of the U.S. Geological Survey (3) 401-408
Digital image-processing techniques have been developed to make shaded-relief images from digitized topographic data. The resulting images have at least two advantages over aerial photographs: (1) The images are true map projections containing no relief-induced distortion, and (2) tonal variation is unambiguously identified with relief, rather than with snow,...
Origin of lunar light plains

1975, Journal of Research of the U.S. Geological Survey (3) 379-392
Most Cayley-type Imbrian-age plains deposits and adjacent mantled slopes, including those at the Apollo 16 site, may be composed at least near the surface of ejecta from the Orientale basin, the youngest multiringed impact basin on the Moon. The distribution and apparent age of the plains deposits and preliminary data...
Early Ordovician gastropod opercula and epicontinental seas
Ellis L. Yochelson
1975, Journal of Research of the U.S. Geological Survey (3) 447-450
Collections made for some years from Lower Ordovician rocks by many geologists have established that the heavy calcareous operculum of the gastropod Ceratopea is almost never found associated with a shell and that commonly this operculum is secondarily silicified. Ceratopea may have lived in a stressed habitat and may have...
Status of the wolf in Michigan, 1973
J. Hendrickson, W. L. Robinson
1975, American Midland Naturalist (94) 226-232
Wolf (Canis lupus) numbers in Michigan's Upper Peninsula declined from an estimated 45-50 animals in the mid-1950s to near extinction in 1973, probably because of overharvesting through the bounty system. Sporadic breeding and occasional immigration of wolves from Ontario and Minnesota are postulated to be the factors tending to maintain...

1975, Wilson Bulletin (87) 187-195
Six male Red-winged Blackbirds scattered throughout 2 marshes were vasectomized in 1971, and their females began laying infertile clutches in 5 days. However, of 39 clutches on their territories, 27 (69%) were fertile. In 1972, 30, 50, and 100% of the males in 3 small isolated marshes were vasectomized, and...
An empirical note on firm performance in government contract markets
Emil D. Attanasi, S. R. Johnson
1975, The Journal of Industrial Economics (23) 313-320
Public construction and, in particular, highway construction account for a large proportion of the non-defense expenditures by the government. Con- tracts for highway construction are let almost exclusively through a sealed tender process. Competitive bidding is used to encourage price competition. There is, however, a problem in insuring that the...
