The Child's Sex And Birth Ordinal Position: Its Effects Upon Fathers' Interaction With Their Natural Five-Year-Old Children In A Selected Provo Utah Mormon Sample, D. Wayne Brown Jr. Jan 1979

The Child's Sex And Birth Ordinal Position: Its Effects Upon Fathers' Interaction With Their Natural Five-Year-Old Children In A Selected Provo Utah Mormon Sample, D. Wayne Brown Jr.

Theses and Dissertations

Thirty-nine fathers were observed to determine if they interact differently with their child as a result of the child's sex or birth ordinal position.

Results indicated that fathers expected more of their sons, had a higher readiness of explanation for them, and criticized them more often. Fathers gave more praise, physical contact and supportive behavior to their daughters. Birth ordinal effects paralleled and interacted wiith the child's sex.

Stepwise regression yielded a mean value of 44.16 in explaining the overall variance in dependent variables. It emphasized the number of hours the father spent with his child and family, the father's …

Raptors Of The Uinta National Forest, Utah, James A. Mosher, Clayton M. White, Joseph R. Murphy, M. Alan Jenkins Dec 1978

Raptors Of The Uinta National Forest, Utah, James A. Mosher, Clayton M. White, Joseph R. Murphy, M. Alan Jenkins

Great Basin Naturalist

The past and present use of the Uinta National Forest by birds of prey was determined from historical records and surveys conducted during 1973, 1974, and 1975. Data describing the history, present status, and physical characteristics of each nest site were collected, along with the type and intensivity of human activity within a half-mile radius of the nest. In addition, limited data on fall migration of raptors along the Wasatch Front and the food habits of Golden Eagles are presented. Management guidelines, based on the results of this study, are proposed.

Vertical Distribution Of Adult Fish In Pyramid Lake, Nevada, Steven Vigg Dec 1978

Vertical Distribution Of Adult Fish In Pyramid Lake, Nevada, Steven Vigg

Great Basin Naturalist

Inshore and limnetic vertical distribution of adult fish in Pyramid Lake, Nevada was determined from late spring to early fall 1977. The benthic (23 m) inshore area exhibited a relatively diverse composition of five species, while the inshore surface and offshore limnetic zones were composed of over 98 percent tui chubs (Gila bicolor). Vertical fish distribution was associated with temperature and zooplankton distribution.

Contributions To The Biology Of The Woundfin, Plagopterus Argentissimus (Pisces: Cyprinidae), An Endangered Species, Jeffrey N. Cross Dec 1978

Contributions To The Biology Of The Woundfin, Plagopterus Argentissimus (Pisces: Cyprinidae), An Endangered Species, Jeffrey N. Cross

Great Basin Naturalist

The woundfin is a small, streamlined, omnivorous cyprinid that is now limited to the Virgin River basin where it was collected in the mainstream and one tributary during the present study. The woundfin occurred most frequently in runs and over sand substrates and less frequently in riffles and over rock substrates. It was common over at least half of its original range within the Virgin River. It was uncommon in the lower mainstream due to habitat alterations and, presumably, predation by and competition with exotic species.

Chemical Vapor Deposited Molybdenum Films For Use In Photothermal Conversion, David D. Allred, G. E. Carver, B. O. Seraphin Nov 1978

Chemical Vapor Deposited Molybdenum Films For Use In Photothermal Conversion, David D. Allred, G. E. Carver, B. O. Seraphin

Faculty Publications

High infrared reflectance, coupled with higher solar absorptance, is required for efficient photothermal conversion. Converters can be fabricated by depositing an absorber on a highly reflecting metal. The absorber functions in the visible, yet becomes transparent in the near infrared, allowing the metal to suppress the thermal emittance. Economic considerations demand the use of thin films, rather than bulk materials. The thin film reflector must be capable of withstanding high temperatures of operation. Compatibility of the reflector with the substrate below, and the absorber above, is required for long-time service. Highly reflective silver films suffer reflectance losses by agglomeration, and …

Chemical Vapor Deposited Amorphous Silicon For Use In Photothermal Conversion, David D. Allred, D. C. Booth, M. Janai, G. Weiser, B. O. Seraphin Nov 1978

Chemical Vapor Deposited Amorphous Silicon For Use In Photothermal Conversion, David D. Allred, D. C. Booth, M. Janai, G. Weiser, B. O. Seraphin

Faculty Publications

Efficient photothermal conversion requires surfaces of high solar absorptance and low thermal emittance. This can be accomplished by the tandem action of a good infrared reflector overlaid by a film of sufficient solar absorptance that is transparent in the infrared. Crystalline silicon is a suitable candidate for the absorber layer. Its indirect band gap, however, results in a shallow absorption edge that extends to far into the visible. In contrast, the absorption edge of amorphous silicon is steeper and located farther into the infrared, resulting in a larger solar absorptance. We report on the fabrication of amorphous silicon absorbers by …

An Emulsion Dye Laser, Kenneth Lee Matheson, James M. Thorne Nov 1978

An Emulsion Dye Laser, Kenneth Lee Matheson, James M. Thorne

Faculty Publications

A laser dye which is insoluble in water has been dissolved in hexane and emulsified in a water matrix. When pumped with a nitrogen laser, this mixture was observed to lase. The emulsion is superior to a simple hexane solution because the excellent thermo-optical properties of the water matrix help prevent refractive-index gradients from degrading laser performance. This is a useful characteristic for flash-pumped dye lasers, laser-pumped dye lasers, and liquid filters. Another type of solvent system, a critical solution, is also discussed. For certain dyes, a critical solution has even better thermo-optical properties because of its ability to absorb …

Current Status Of Cutthroat Trout Subspecies In The Western Bonneville Basin, Terry J. Hickman, Donald A. Duff Jun 1978

Current Status Of Cutthroat Trout Subspecies In The Western Bonneville Basin, Terry J. Hickman, Donald A. Duff

Great Basin Naturalist

Recent discoveries of native cutthroat trout populations in desert mountain ranges on the western fringe of the Bonneville Basin have prompted intensified management efforts by state and federal agencies. Analysis of Snake Valley cutthroat specimens in Trout Creek, Deep Creek Mountain Range, Utah, indicate this is a pure strain of the trout which once inhabited Pleistocene Lake Bonneville and which was thought to be extinct in Utah. The Snake Valley cutthroat is similar to Salmo clarki utah of the eastern Bonneville Basin; however, electrophoretic and morphomeristic analysis show unique genetic differences brought about by long-term isolation (8,000 years) from the …

Primary Productivity In Meromictic Big Soda Lake, Nevada, R. P. Axler, R. M. Gersberg, L. J. Paulson Jun 1978

Primary Productivity In Meromictic Big Soda Lake, Nevada, R. P. Axler, R. M. Gersberg, L. J. Paulson

Great Basin Naturalist

In situ radiocarbon uptake measurements conducted at Big Soda Lake, Nevada, indicate that (i) bacterial photosynthesis comprises an important fraction (30 percent) of the lake's total primary production and (ii) bacterial chemosynthesis contributes significantly to organic particle production. The results of nutrient enrichment bioassay experiments support Hutchinson's prediction that availability of inorganic nitrogen, rather than phosphorus, limits primary production in the mixolimnion. Nutrient additions of NO3–N with Fe+3 most stimulated 14C uptake.

Leo Schelbert And Hedwig Rappolt, Eds,: Alles Ist Ganz Anders Hier, Bruno Gujer

Swiss American Historical Society Newsletter

To emigrate to the United States today does not seem to be the great adventure anymore that it once was. The material inconveniences of the move are negligible, the problems of psychological adjustment trivial compared to the physical hardships and culture shocks endured by the immigrants in the eighteenth and nineteenth century.
