Considerable research on ticks has been done since it was discovered that the Rocky Mountain wood tick, Dermacentor andersoni Stiles, was a principal vector of Rocky Mountain spotted fevero Additional disease agents of man are also transmitted by D. andersoni. This tick and a closely related species, Dermacentor parumapertus Neuman, occur commonly in Utah. The two species are often closely associated, although D. andersoni is believed to occur in the mountains, whereas D. parumapertus is in the desert valleys. Diseases affecting animals in nature are transmitted by ticks of both species. Consequently, any interaction between the two may be influential in the maintenance of diseases in nature communicable to man and his domestic animals.

The Swan Peak Formation in southeastern Idaho and north-central Utah is a sedimentary unit consisting of orthoquartzite, sandstone, siltite, shale, and limestone. The formation is divisible into three members, and the lower two members each are divisible into two informal lithologic subunits. The lower member consists of a lower subunit of gray, calcareous sandy siltite composed of subangular to subrounded quartz grains cemented by quartz overgrowths, calcite, or iron oxide, and an upper subunit of black shale with minor interbedded silty quartzose sandstone and biomicrite (limestone). The middle member consists of a lower subunit of interbedded pale green shale and yellowish brown silty orthoquartzite and an upper subunit of purple orthoquartzite. The brown orthoquartzite consists of well-sorted, well-rounded very fine sand- to silt-sized quartz grains cemented by quartz overgrowths which are in optical continuity with the grains they surround. The purple orthoquartzite consists of wellsorted, well-rounded, very fine to medium sand-sized quartz grains cemented by quartz overgrowths and hematite. Hematite gives the rock its purple color. gydroxylapatite is locally abundant. The upper member is an orthoquartzite consisting of very fine to medium sand-sized, well-sorted, well-rounded quartz grains cemented by quartz overgrowths. The gastropod Murchisonia (Hormotoma) sp., the first body fossil found in the upper member, is reported. Previous work has shown that the upper member of the Swan Peak Formation and the Eureka Quartzite are similar in lithology, stratigraphy, and trace fossils. The Eureka Quartzite in the Newfoundland Range is a very fine to medium sand-sized, well-sorted, well-rounded orthoquartzite cemented predominantly by quartz overgrowths, locally by dolomite. The petrographic similarities of the two units, shown in the present study, strengthens their proposed correlation. High percentages of well rounded, polycrystalline and undulatory extinction quartz show that source areas for the Eureka Quartzite and Swan Peak Formation probably were immature sandstones or quartzites of Cambrian or Precambrian age, and./or exposed igneous or metamorphic rocks. The source for most of the sand probably was the Northwest Montana Uplift, although local sources along the Uinta Uplift undoubtedly played a minor role in supplying hydroxylapatite to the middle member and fine-grained elastics to the lower member.

Salary differentials by rank were studied at the University of Utah and Utah State University on a departmental basis. Multiple regression equations were developed from criteria at Utah State University which were used to predict individual salaries for professional staff members at the University of Utah. Thirteen of the fourteen multiple regression equations developed showed statistical significance at the .05 level and twelve departments were significant at the .01 level. Salary comparisons by rank were considerably reduced as a result of the department by department analysis.

This study compares insect and cattle consumption of crested wheatgrass (Agropycon spp.) on a site in Sterling Ranch, Utah County, Utah. The hypothesis tested is that insect consumption in general, and specifically consumption by Labops hesperius Uhler, significantly reduces total available cattle forage. Labops and grasshoppers were probably the major cause of secondary damage at the study site, while the impact of thrips is unknown. A detrimental impact on range was suggested by the data, as insects consumed forage equivalent to 2.8 animal units per month, while cattle consumed forage equivalent to 2.1 animal units per month at the study site. Based on a grazing fee of $1.60 per animal unit per month, this represents a loss of $3.50 per acre. Although a low level Labops population was present at the time of the study, potential exists for this population to reach higher level s that would cause much higher levels of damage. Crested wheatgrass, the major vegetation at the study site, is capable of resuming growth in the fall if there is sufficient moisture. Because there is only one generation of Labops per year, fall herbage production would not suffer Labops damage, but may suffer damage by other insects that are present in the fall.

A survey was performed to compare basic health education knowledge between sophomore students at Utah State University and sophomore students at the University of Utah . This was performed through the use of a questionnaire consisting of 40 questions covering the following eight areas of prominence in health education: 1. Alcohol and tobacco 2. Community health and communicable disease 3. Consumer health 4. Drugs and narcotics 5. Food fads and medical quackery 6. Mental health 7. Personal health 8. Sex education This questionnaire was administered through the mail to 250 randomly selected students at the two universities. When responses were received they were scored and keypunched on IBM-5080 cards . The cards were then processed through the IBM-350 Model 44 computer using Analysis of Variance and the Quest Program. Computation of student "T 11 scores verified that students at the University of Utah were superior in health knowledge at the .05 level of significance based on the one tailed test. The University of Utah last year required a basic health education class of all freshmen . At Utah State University such a class is not required or even offered. The f act that University of Utah students were superior verified that positive learning of health education did increase through specific instruction.

The Middle Cambrian Ute Formation was studied in the Bear River Range and the Wellsville Mountains of north-central Utah and southeastern Idaho. The depositional textures and sedimentary structures found within the rocks were compared with similar modern sediments and ancient rocks to determine depositional environments, paleogeography, and diagenetic alterations. The rocks of the Ute Formation were divided into five basic types. These five rock types were formed within four identifiable lithofacies: 1) elastic marine shelf; 2) carbonate marine shelf; 3) agitated shoal; and 4) quiet-water shoal. The sequence of elastic and carbonate sediments is believed to have been deposited in a shallow, subtidal environment. Clastic sediments from the east and northwest periodically prograded over the carbonate sequences. A major regression marks the base of the Ute Formation. This was followed by a series of transgressions and regressions, until a major transgression occurred near the end of the deposition of the Ute. Paleomagnetic and faunal evidence suggest the study area was within 10° of the equator during the Middle Cambrian. Clay mineralogy of insoluble residues indicates a humid, tropical climate. Primary diagenetic features are compaction, micritization, and cementation. Secondary diagenetic changes include the inversion of high-magnesium calcite to low-magnesium calcite, aggrading neomorphism, stylolitization, fracturing, and calcite infilling. Partial dolomitization of grains and/or matrix is believed to result from the release of magnesium due to the decomposition of magnesium-rich, organic matter. The formation of a lens-shaped body of dolostone may have resulted from dolomitization by a magnesium-rich fluid circulating along faults.

Many of the beef cattle in the Great Basin area are maintained part or all of the year on rangelands. Most of those going on to desert ranges for only part of the year go on during the late fall, winter, and early spring. It is estimated that 50-60 percent of the 600,000 beef cattle grazing on range lands in Utah graze on the one-fourth million acres of desert or semi-desert sometime during the year.

The English spoken in the United States has traditionally been divided into six dialect regions: New England, Mid-Atlantic, Southern, Midland, Northern, and Western. The acoustic properties of American English spoken in the Southern and Northern dialect regions have been the subject of intense research, but the acoustic properties of the Western dialect region have not been analyzed as thoroughly. The umbrella term, Western American English, includes the English spoken in a large geographic area that stretches from Montana, Wyoming, Colorado, and New Mexico to the Pacific coast. Research that has focused on the Western dialect has included participants from several states, which discounts the idea that smaller dialectical differences may exist within the West. This study describes several acoustic properties of American English as it is spoken in the state of Utah. Data collected from target hVd words were used to determine vowel formant frequency patterns using F1 and F2 values of monophthongal and diphthongal vowels, and calculate the vowel space area. Differences in vowel placement and vowel space area were found between the English spoken in Utah and the Northern, Southern, and Midland dialect regions. Similar to characteristics found in Western English, an analysis of the vowel productions in speakers from Utah indicated a fronted /ʊ/, as well as a near merger of /ɑ/ and /ɔ/. However, the analysis also revealed differences in Utah English when compared to the larger Western dialect region. In particular it was found that, unlike descriptions of Western English, Utah English speakers produced /æ/ with a relatively higher F1 than /ɑ/. The vowel space area of Utah English was found to be smaller than the vowel space area of Northern English, but larger than the vowel space area of Southern or Midland speakers.

The first missionaries of the Church of Jesus Christ of Latter-day Saints went to Hawaii in 1850. As native converts joined the Church, many desired to gather in Utah with converts from other parts of the world, in order to perform Church ordinances in the temples located there. Until about 1870, Hawaiians were prohibited by their government from leaving the Islands permanently. As the laws were relaxed they came to Utah a few at a time with returning missionaries until by 1889 about seventy-five were living in Salt Lake City.Cultural and social problems arose causing the Church officials to decide to locate all the Polynesians in one place by themselves. Under the direction of the First Presidency of the Mormon Church a committee of three former Hawaiian missioanries and three natives selected the ranch of John Irch in Skull Valley, Tooele County, Utah as the site for a Polynesian colony. A Church-controlled corporation was established to purchase and hold the colony's properties. The Polynesians were hired to work on the ranch.A townsite was laid out, lots were sold and homes were bult for the colonists. The colony was named Iosepa, in honor of the sixth president of the Church, Joseph F. Smith, who had served as a missionary among the Hawaiians and was solicitous of their welfare.For the first decade, the company operated at a loss due to the financial difficulties of the 1890's. Gradually financial conditions improved, the company began to feed more livestock, a store was opened and then Iosepa began to realize a profit.At first Iosepa was isolated from other Utah communities. The only way in or out of the colony was by foot or horses. Its post office was in Grantsville, about thirty miles to the northeast. In 1906 the Western Pacific Railroad Company built a line through Utah passing through Timpie, fifteen miles north of Iosepa. A Stagecoach line was established between Timpie and the colony and mail services were extended to the settlement. About the same time, a long distance telephone line gave the colonists a means of rapid communciation with the outside world. By about 1910 the Hawaiians were enjoying as many of the amenities of modern life as any other Utah community its size.Ecclesiastically Iosepa held a unique position in the Church. As a mission branch, all its reports went directly to the First Preidency. Religious leadership was vested in a returned Hawaiian missionary. Hawaiian members usually served as officers in the auxillary organizations.Leprosy and various illnesses caused some concern in the colony, but by 1900 the lepers had died. As doctors became more attainable and as the Hawaiians became more acclimated, problems of sickness decereased.In 1915 the Church announced that a temple was to be built at Laie, Hawaii. Upon hearing this some of the Hawaiians announced that they were returning to the Islands. Soon the movement to return was under way and all were swept with it. By 1917 all had returned to the Islands but one family which remained in Salt Lake City. That fall the Deseret Livestock Company purchased the Iosepa property and Utah's Polynesian colony ceased to exist.Some have asserted that leprosy, other sickness, financial failure or failure of the Polynesians to become acclimated to the area caused the failure and closing of the colony. Each one of these problems was overcome years before the colony's end. The colony was a success. It had been established for a purpose; when its purpose was fulfilled it ceased to exist.

Moab, located in southeastern Utah, began as an agricultural village, in accordance with the economy of early Utah. However, Moab's growth was limited by a restricted physical site. The purpose of this study is to trace the development of the economic functions of Moab in relation to its resource base. Despite the physical limitations of the area, agriculture remained the chief economic activity up to the mid-twentieth century. Periodic booms in speculative mining were only temporary and not significant to the permant economy of the community.However, in the 1950s, a spectacular uranium boom brought unprecedented growth to the town. As the uranium boom slackened, economic and population decline threatened the town's new status. Potash production and tourist-service industries emerged to buoy up the sagging economy. Although the economy was aided by the addition of other activities, the sectors of the economy still remained disproportionately unbalanced in comparison to the norm. The future economic stability of the community remains questionable unless balance can be attained.
