The Level And Determinants Of Burnout Of Mormon Mothers In A Utah Suburban Town, Christina Mordock Jan 1990

The Level And Determinants Of Burnout Of Mormon Mothers In A Utah Suburban Town, Christina Mordock

Theses and Dissertations

The purpose of this study was to examine burnout in Mormon mothers in a suburban Utah town. Specifically the amount and some determinants of burnout among these Mormon women was studied. A random sample of 266 Mormon mothers completed a questionnaire and a modified version of the Maslach Burnout Inventory (MBI) which consisted of three subscales, (Emotional Exhaustion, Depersonalization, and Personal Accomplishment), and two categories in each subscale (Frequency and Intensity). The subjects scored in the moderately burned out category in each subscale. Significant relationships were found between the amount of burnout and the following: the age of the mother, …


Radio Transmitter Attachment For Chukars, Bartel T. Slaugh, Jerran T. Flinders, Jay A. Roberson, M. Ray Olson, N. Paul Johnston Oct 1989

Radio Transmitter Attachment For Chukars, Bartel T. Slaugh, Jerran T. Flinders, Jay A. Roberson, M. Ray Olson, N. Paul Johnston

Great Basin Naturalist

Thirty-seven Chukars (Alectoris chukar), fitted with conventional poncho-type radio transmitters, were released on Antelope Island in Utah's Great Salt Lake. Twenty-seven removed their radios, averaging three days after release. The remaining 10 died from predation (average 15 days). Twenty-two Chukars with pleated and six with harness ponchos were then released. Five of the pleated ponchos were removed (average four days), and 17 resulted in mortality (average two days). All six harness poncho-equipped birds were dead the following day. A consequential laboratory study comparing various attachment methods (conventional, pleated, harness, and "irreversible" flange poncho vs. bellystrap and wingstrap backpack) …


Winter Habitats And Foods Of Blue Grouse In The Sheeprock Mountains, Utah, Peter J. Perkins, Frederick G. Lindzey, Jay A. Roberson, Gregory Mcdaniel, Randy Berger Apr 1989

Winter Habitats And Foods Of Blue Grouse In The Sheeprock Mountains, Utah, Peter J. Perkins, Frederick G. Lindzey, Jay A. Roberson, Gregory Mcdaniel, Randy Berger

Great Basin Naturalist

Winter habitat use and food habits of Blue Grouse (Dendragapus obscurus) were studied in an isolated Utah desert mountain range that contained little typical Douglas-fir (Pseudotsuga menziesii) winter habitat. Habitat use was concentrated in the Douglas-fir and pinyon (Pinus edulis)–juniper (Juniperus spp.) habitat. Douglas-fir and pinyon pine were the most consumed foods. Other foods that represented >15% of the composition of an individual fecal sample were limber pine (Pinus flexilis), mahogany (Cercocarpus ledifoliu), juniper, and an Anteunaria–Cirsium type. The breadth in winter diet indicates that Blue Grouse may …


Changes In Mule Deer Size In Utah, Dennis D. Austin, Robert A. Riggs, Philip J. Urness, David L. Turner, John F. Kimball Jan 1989

Changes In Mule Deer Size In Utah, Dennis D. Austin, Robert A. Riggs, Philip J. Urness, David L. Turner, John F. Kimball

Great Basin Naturalist

Trends in age-specific, eviscerated carcass weights were determined for hunter-harvested yearling and two-year-old buck mule deer. Carcass weights declined over an 11-year period from two areas of similar management, but with independenly collected data sets. Carcass weights also declined between the opening and second weekends of the hunt. Management implications are discussed.


The Development And Failure Of Historic Agricultural Communities Of Utah: A Case Study Of Johns Valley, Utah, Wayne R. Shelley Jan 1989

The Development And Failure Of Historic Agricultural Communities Of Utah: A Case Study Of Johns Valley, Utah, Wayne R. Shelley

Theses and Dissertations

Many agricultural communities have developed in Utah since the first settlement, but many no longer exist today. Some of these early communities experienced a "boom and bust," while others struggled for several years and were eventually abandoned. Johns Valley is a good example of these historic communities, as it experienced rapid growth and times of success and prosperity, yet it struggled and was eventually abandoned.
The situation in Johns Valley, from its early settlement to its demise, demonstrates the hope of the people who settled there and their efforts to make Johns Valley a productive and successful area. History also …

Computer Analysis Of Cross Sections Of Leaves Of Chrysothamnus Taxa And Their Relation To Environmental Conditions, J. Huang, W. M. Hess, D. J. Weber, E. D. Mcarthur, S. E. Meyer, R. Seegmiller Jul 1988

Computer Analysis Of Cross Sections Of Leaves Of Chrysothamnus Taxa And Their Relation To Environmental Conditions, J. Huang, W. M. Hess, D. J. Weber, E. D. Mcarthur, S. E. Meyer, R. Seegmiller

Great Basin Naturalist

Thirty-eight accessions of 20 taxa (species and subspecies) of Chrysothamnus from a range of environments were grown in a uniform garden. During mid-June, terminal and lateral leaves were removed, fixed, and processed for light-microscopy studies. Area and perimeter measurements of ink tracings of midleaf vein cross sections were measured using computer-scan techniques. Leaf area and perimeter were compared with vein perimeter and area measurements. Area and perimeter of these Chrysothamnus leaves varied in response to the environment at the collection location. Plants native to hot, dry conditions had small, thick leaves, whereas plants native to cooler, more mesic conditions had …


Aspects Of Bald Eagle Winter Behavior In Rush Valley Utah: A Telemetry Study, Neil B. Sabine Dec 1987

Aspects Of Bald Eagle Winter Behavior In Rush Valley Utah: A Telemetry Study, Neil B. Sabine

Theses and Dissertations

The diurnal behavior and nocturnal roosting patterns of 28 bald eagles outfitted with tail-mounted radios were investigated in Rush Valley, Utah between January and March 1982-1984. Casting analysis and feeding observations indicated the principal food source was jackrabbit carrion. Jackrabbit availability declined from 1982 to 1984 and eagles responded by; 1) roosting closer to feeding sites, 2) shifting from canyon to valley roosts, 3) arriving later at and departing earlier from roosts, 4) decreasing diurnal activity, and 5) decreasing residence time. Foraging efficiency appeared to be maximized by experienced eagles using familiar feeding areas and by naive birds monitoring their …

Distribution Of Vertebrates Of The Bighorn Canyon National Recreation Area, Stanley H. Anderson, Wayne A. Hubert, Craig Patterson, Alan J. Redder, David Duvall Jul 1987

Distribution Of Vertebrates Of The Bighorn Canyon National Recreation Area, Stanley H. Anderson, Wayne A. Hubert, Craig Patterson, Alan J. Redder, David Duvall

Great Basin Naturalist

During a survey of the vertebrates in the Bighorn Canyon National Recreation Area, 46 mammal, 210 bird, 9 reptile, 5 amphibian, and 28 fish species were found. Habitat structure and moisture were two environmental variables associated with species numbers across this 1,820-ha area. Eight distinct habitats were evaluated. In coniferous forests, 27% of the birds and 54% of the mammals were observed. Sagebrush/grasslands and upland shrublands were very arid and had relatively few vertebrates. Five introduced game birds occurred in sagebrush habitat. Riparian and wetland habitats had the largest number of unique vertebrates, 38 and 77 respectively. The establishment of …
