All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The increase in household income attributed to expenditures by Utah motor vehicle tourists from June 15 to September 5, 1969, was estimated using income multipliers from input-output analysis. Tourist expenditures were gathered through the distribution of postage-paid diaries to non-residents entering Utah. Expenditures were also segregated for Cache County, Utah. The income multipliers from state and county input-output models were used to estimate the impact of applying the state model to county data.

Approximately 927,250 tourist parties to Utah spent an estimated $37,842,816, increasing household income $65,018,557. Likewise, approximately 67,709 tourist parties spent an estimated $798,966 in Cache County. The …

The Hyrum And Beirdneau Formations Of North-Central Utah And Southeastern Idaho, James F. Eliason

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Hyrum and Beirdneau Formations of North-central Utah and Southeastern Idaho represent rocks of late Middle Devonian (Givetian) to upper Upper Devonian (Famennian) age. They are disconformably underlain by the Early Devonian Water Canyon Formation in most cases and disconformably overlain by the Devonian-Mississippian Leatham Formation or the Mississippian Lodgepole Formation.

The Hyrum Formation is divided into five members based on lithology and color changes. The five members are: (1) Samaria, (2) Lower Dolomite, (3) Lower Carbonate-detritus, (4) Upper Dolomite, and (5) Upper Carbonate-detritus Members. The Samaria Member is the only fossiliferous unit within the Hyrum Formation.

Role Of Lamb Pregastric And Gastric Extracts In Cheese Manufacture, Ramjibhai V. Chaudhari

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lamb pregastric (PGE) and gastric extracts (GE) have been evaluated for their role in Italian cheese flavor production. Both have been shown to produce increases in free fatty acids and in non-protein-nitrogen during incubation with milkfat and casein substrates as well as in cheese substrates. Gastric lipase and cathepsins are considered to be the additional active agents in GE. Parmesan cheese manufactured with PGE and GE added to the curd was superior in flavor when both were employed, and either extract alone was better than the uninoculated control. An assay for GE proteolytic activity has been proposed which involves the …

The Father Role As Seen By A Group Of College Student Fathers, Devona Alice Dean Luke

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Some literature implies the modern father has abdicated his place as head of the family, but little research has been done to examine the role of the father in the modern American family.

Intensive interviews of 18 college student men who each had at least two children showed that these men are very much concerned with fatherhood and participate actively in the rearing of their children. They feel the father has at least as much responsibility for the rearing of their children as the mother, possibly more. They are involved more in some dimensions of parenthood than others. Those fathers …
