Grouse and Quails of North America by Paul A. Johnsgard
Alectoris chukar (Gray) 1830
Alectoris graeca (Meisner)
Other vernacular names: Chukor, Indian hill partridge, rock partridge (refers to graeca only).
Range: Native to Eurasia, from France through Greece and Bulgaria (typical graeca) southeastward through Asia Minor and southern Asia (typical chukar). These two populations should probably be regarded as separate species (Watson, 1962a, b), and all of the introduced United States stock is apparently referable to A. chukar. The racial origin of the birds introduced into North America is varied and includes not only Indian stock (probably A. c. chukar, as recognized by Sushkin, 1927) but …
Keys To Identification, Paul A. Johnsgard
Keys To Identification, Paul A. Johnsgard
Grouse and Quails of North America by Paul A. Johnsgard
The three following keys can be used to identify unfamiliar species of North American grouse or quails that may be examined in the hand. Unless one is certain that the bird represents either a grouse or a quail, he should begin with the first key. The procedure, as in the use of all such keys, is to choose which of the two initial alternative descriptive couplets (A and AA) best fits the unknown bird. Having chosen one of these, proceed to the choice of couplets (B and BB) occurring immediately below the couplet chosen, without further regard for descriptions listed …

Chemical Quality Of The Groundwater System In Hall County, Nebraska, Jon C. Atkinson
Chemical Quality Of The Groundwater System In Hall County, Nebraska, Jon C. Atkinson
Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
Hall County, an area of 540 square miles, is in south-central Nebraska. The Platte River flows east-northeasterly across the county from its southwest corner; the Wood River, which is tributary to the Platte within Hall County, enters the county about 6 miles north of the southwest corner. Analysis of streamflow data indicates that the Platte and Wood Rivers are losing streams in Hall County. Based on an 18-year period, October 1953 through September 1971, the average annual losses between gaging stations were 48,100 and 1,940 acre-feet, respectively.
The county is underlain by unconsolidated deposits of Quaternary age. These deposits mantle …

Some Forms And Functions Of Contrast In The Islendingasogur, Duane Victor Keilstrup
Some Forms And Functions Of Contrast In The Islendingasogur, Duane Victor Keilstrup
Department of Modern Languages and Literatures: Dissertations, Theses, and Student Research
BACKGROUND
Concerning current research to 1973 in the Old Norse sagas generally, R. G. Cook suggests that scholars turn more of their attention to the finished product, that is, a return to Grimm’s principle of "die Andacht zum Text," and to a responsible historical criticism which is also responsive to the artistic integrity of the text. He thus believes that we should read the sagas as works of art by concentrating on what we find in them and not so much where and when they might have originated, as scholars in this field have tended to do. Hence, it is …

Genetic Studies Of Induced Mutants In Melilotus Alba Iii. Folded Leaflet, Elongatyed Stem, And Short-Petiole Dwarf, R. R. Ronnenkamp, Francis A. Haskins, Herman J. Gorz
Department of Agronomy and Horticulture: Faculty Publications
Observations of the F1, F2, and F3 progenies of crosses between normal annual Melilotus alba Desr. and three mutants, folded leaflet, elongated stem, and short-petiole dwarf, indicate that each of the mutant characters is controlled by a single recessive gene. Proposed symbols for the three mutant genes are f, el, and dsp, respectively. In limited tests for linkage, el appeared to be linked (12% recombination) to a gene for multifoliolate leaves (Mf). No linkage was detected between f and Mf, cu (low o-hydroxycinnamic acid), or b (low …

Bacteriophage Φ6: A Lipid-Containing Virus Of Pseudomonas Phaseolicola, Anne K. Vidaver, R. K. Koski, James L. Van Etten
Department of Plant Pathology: Faculty Publications
The purification and properties of a lipid-containing bacteriophage, φ 6, are described. The phage contains a lipid envelope which is probably essential for infection. Infectivity of φ 6 was lost in the presence of organic solvents, sodium deoxycholate, and phospholipase A. The fatty acid composition of the phage lipid was similar to that of the Pseudomonas phaseolicola host cells. The phage was composed of about 25% lipid, 13% RNA, and 62% protein. The buoyant density of φ6 was 1.27 g/ml in cesium chloride. The morphology of φ6 was unusual; it had a polyhedral head of about 60 nm surrounded by …
Reproduction In The Red Squirrel (Tamiasciurus Hudsonicus) In Colorado, Richard A. Dolbeer
Reproduction In The Red Squirrel (Tamiasciurus Hudsonicus) In Colorado, Richard A. Dolbeer
United States Department of Agriculture Wildlife Services: Staff Publications
Information on reproduction of the red squirrel (Tamiasciumrs hudsonicus) can be gleaned from studies in the northeastern United States (Klugh, 1927; Hamilton, 1939; Layne, 1954) and in western Canada (Miller, 1970; Smith, 1968; Kemp and Keith, 1971; Wood, 1967). However, there is a paucity of information on reproduction from the mountainous regions of the western United States. This paper presents reproductive information on the red squirrel from Colorado and helps fill this void. In addition, the reproductive strategy of red squirrels is briefly compared with that of snowshoe hares.
Dual Labor Markets: A Theory Of Labor Market Segmentation, Michael Reich, David M. Gordon, Richard C. Edwards
Dual Labor Markets: A Theory Of Labor Market Segmentation, Michael Reich, David M. Gordon, Richard C. Edwards
Department of Economics: Faculty Publications
A growing body of empirical research has documented persistent divisions among American workers: divisions by race, sex, educational credentials, industry grouping, and so forth (F. B. Weisskoff, B. Bluestone, S. Bowles and H. Gintis, D. Gordon, 1971 and 1972, B. Harrison, M. Reich, H. Wachtel and C. Betsey, and H. Zellner). These groups seem to operate in different labor markets, with different working conditions, different promotional opportunities, different wages, and different market institutions.
These continuing labor market divisions pose anomalies for neoclassical economists. Orthodox theory assumes that profit-maximizing employers evaluate workers in terms of their individual characteristics and predicts that …
Quasi-Landau Spectrum Of A Hydrogen Like Atom In A High Magnetic Field, Anthony F. Starace
Quasi-Landau Spectrum Of A Hydrogen Like Atom In A High Magnetic Field, Anthony F. Starace
Anthony F. Starace Publications
A two dimensional semiclassical approximation is used to examine the σ polarization spectrum of a hydrogen like atom in a strong magnetic field. Resonances above the zero field ionization limit are found and their energy separations are computed over the region from the ionization limit to 40 ħωc above, where ωc is the cyclotron frequency, for magnetic fields of 10, 17, 25, 32, 40 and 47 kG. At the ionization limit the separation between resonances is found to be 1.500 ħωc, independent of magnetic field strength, which is in agreement with a separation of 1.5 ħω …

The Culture Of Poverty Debate: Some Additional Data, Barbara E. Coward, Joe R. Feagin, J. Allen Williams Jr.
Department of Sociology: Faculty Publications
In this paper we briefly review relevant research on the culture of poverty and set our findings within the general context of culture of poverty arguments. Data from a community survey in a Southwestern city are analyzed using Oscar Lewis’ four major culture of poverty dimensions: 1) the individual, 2) the family, 3) the slum community, and 4) the community’s relation to society. In our study a sample of 271 black respondents was divided into two groups, here termed the “poor” and the “non-poor.” In noting all the broad traits studied in all dimensions taken together, some support for Lewis’ …
Evaluation Of An Experiment In Computer -Assisted Tutoring, Stephen L. Cunningham, Robert Fuller
Evaluation Of An Experiment In Computer -Assisted Tutoring, Stephen L. Cunningham, Robert Fuller
Robert G. Fuller Publications
It was made apparent from the presentations at the Conference of Computers in Undergraduate Science Education that very few Computer-Assisted Instructional (CAI) programs in physics attempt to evaluate the performance of computer- tutored students in comparison with a control group. In this note, we discuss an experiment in which 23 beginning physics students out of a class of 64 were given a computer-administered tutoring test in place of the regular review recitation session prior to an hour exam on relativity. The performance of the computer-tutored group on the exam was compared to the performance of the rest of the class.

Review Of Aldo Scaglione, The Classical Theory Of Composition: From Its Origins To The Present—A Historical Survey, Thomas Nelson Winter
Review Of Aldo Scaglione, The Classical Theory Of Composition: From Its Origins To The Present—A Historical Survey, Thomas Nelson Winter
Department of Classics and Religious Studies: Faculty Publications
This is more bibliothèque than book. A labyrinthine gold mine, but mapped. It presents theories and ideals of style and composition from Aristotle and Dionysius to Weil and Jespersen. Also Chomsky. The historic sweep stuffs them somehow between two covers, finding and interweaving illustrations for everything, while showing developmental lines. One can read this volume and then see one’s Vergil or Montaigne with new eyes and new appreciation.
