Ducking The Diversity Issue: Newspapers’ Real Failure Is Performance, Ted Pease

Journalism and Communication Faculty Publications

Perhaps we've paid too much attention to issues of hiring minorities and diversifying newsrooms, avoiding the tougher questions of content, coverage and newspapers' role in a pluralistic society. After each annual newsroom nose-count is completed, where do newspapers stand on issues of performance?

The Daytime Wind In Valleys Adjacent To The Great Salt Lake, G. L. Stone, D. Hoard

All U.S. Government Documents (Utah Regional Depository)

In 1986 Los Alamos National Laboratory was engaged by the US Army to study the meteorological aspects of emergency preparedness at several sites where toxic materials are stored and handled. The project included a series of tracer and meteorological field experiments in the vicinity of the Tooele Army Depot, 60 km southwest of Salt Lake City, Utah. These experiments generated a large data set for validating numerical simulations and for empiracal analyses of the local meteorology. This paper discusses the main characteristics of the daytime, up-valley flow at the Utah site, including frequency of occurrence, horizontal and vertical structure, and …

Effects Of Alternative Furrow Irrigation Parameters On Pesticide Movement In Cropped Areas In Utah, Antonio Maria Requena, Ahmad Yar Ranjha, Richard C. Peralta, Howard M. Deer, Majid Ehteshami, Robert W. Hill

Civil and Environmental Engineering Faculty Publications

Production of adequate supplies of food and fiber currently requires that pesticides be used to limit crop losses caused by insects, pathogens, weeds and other pests. Although pesticides are necessary in today' s agriculture, they can be a serious problem if they reach and contaminate ground water, especially where drinking water needs are met by ground water. The relative reduction of potential ground-water contamination due to agricultural use of pesticides was analyzed for particular sites in Utah. The potential reduction of pesticides in ground water was considered by utilizing alternative irrigation systems, water management practices and pesticides. A one-dimensional simulation …

Coal Mineral Analysis: A Check On Inter-Laboratory Agreement, G. S. Casuccio, F. A. Gruelich, G. Hamburg, F. E. Huggins, D. A. Nissen, J. M. Vleeskens

Scanning Microscopy

Four laboratories co-operated to test repeatibility and reproducibility of the semi-quantitive Coal Mineral Analysis (CMA) method. CMA is an instrumented image analysis method which identifies mineral particles in coal by chemical composition (energy dispersive X-ray spectroscopy) and size (scanning electron microscopy). The repeatability of weight percent data was better than 0.2 relative standard deviation for most minerals constituting more than five percent of all coal minerals. The type of mineral had no effect on repeatability. Errors arising from counting statistics were shown to be the major source of bias at a given instrument setting.

Inter-laboratory data for the major minerals …

The Development And Evaluation Of Procedures For Recovering Polioviruses And Reoviruses From Culinary Waters Using Electropositively Charged Filters, Kum-Jae Park

Biology

Viruses may be concentrated from culinary water by adsorption to filters. The quantification of these adsorbed viruses requires that they first be eluted from the filters. The elution of poliovirus and reovirus from charge-modified filters was studied in this work. This report describes the effect of varying the pH and composition of several different elution buffers upon the efficiency of virus elution from Virozorb 1 MDS filters. Presumably, the attraction between the virus and the filter media is through ionic interaction or hydrogen bonding or both. To neutralize ionic attraction forces, elution buffer pH was varied so that both the …

Comparative Foraging Ecology Of Sheep And Goats In Caatinga Woodland In Northeastern Brazil, Scott L. Kronberg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Small-ruminant production is an important part of the agricultural economy of northeastern Brazil. However, mild-to-severe undernutrition of livestock is an annual occurrence. Goats can tolerate the marginal forage conditions better than sheep, but the mechanisms underlying their superior tolerance are not understood.

An analysis of animal liveweights at the end of the year-long study indicated that reproducing mixed-race goats gained nearly twice (P<.05) the weight of reproducing hair-sheep of the Santa Ynez breed, and non-reproducing goats gained about 1.2 times more (P<.05) weight than non-reproducing sheep. Daily weight gains of lambs were less (P<.10) than those of kids for their first 80 days of life.

In the wet season, reproducing sheep and goats gained similar (P>.05) weight, while non-reproducing sheep gained more (P≤.05) than non-reproducing goats. Non-reproducing goats had greater (P<.05) forage organic matter intake (OMI) than the corresponding sheep in the two wet periods. In the late-wet period, non-reproducing goats had greater (P<.05) digestible energy intake (DEI) than corresponding sheep did but had similar (P>.05) digestible protein intake (DPI) as sheep.

In the dry …

The Relationship Between Raw Scores On The Kaufman Assessment Battery For Children And School Attendance For Sioux Children Ages 8-12, Mike Cummings

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study was conducted to examine one aspect of construct validity for the Kaufman Assessment Battery for Children (K-ABC). Forty-eight Sioux children at five age levels (8 to 12.5) were used in this study. Relying on theories of child development, most tests of mental abilities have been constructed so that raw scores will increase with age. Pearson r correlation coefficients between age and raw scores were calculated across five age levels for this sample of Sioux children. The Simultaneous-, Sequential-, and Achievement-scale raw scores significantly correlate with age at the .05 level for a one-tailed test of significance. Number Recall …

However, evidence of increased social competence outside …

Day-Specific Time Use By Underachieving Adolescents, Dorothy Jean Cassingham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The data for this study were obtained in October 1989 through the use of a 128-item questionnaire given to students attending an alternative high school in Ogden, Utah. The Rosenberg Self-esteem Scale was included as part of the questionnaire. A total of 166 usable questionnaires were received from the students.

The objectives of this research were to determine if relationships between self-esteem, race, gender, and religion and time use could be detected in at-risk adolescents. The data collected indicate that self-esteem, religion, gender, and race have only slight significance upon the self-reported time use of the alternative high school student. …

Profiles And Trends In Catholic Interfaith Marriages In Utah, Deborah Brown Ascione

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to investigate the phenomenon of interfaith marriage. It is a comparative study using archival data. Utah Catholic interfaith marriage trends over 31 years were compared with three other Catholic dioceses in the United States similar in size or in other demographic characteristics. Results indicate that Utah is not atypical in its intermarriage patterns.

In addition, a micro-level analysis of Catholic interfaith marriages at three points in time was conducted for the Diocese of Salt Lake alone. Statistical analysis employed primarily measures of central tendency. Results indicate that Catholics intermarrying in Utah are older than …

The Needs And Concerns Of The Siblings Of The Deaf-Blind, Lori P. Rowan

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The needs and concerns of the siblings of children who are deaf-blind were studied. Subjects included 12 siblings (eight males, four females) whose families are involved in the Utah Intervener Services Program.

Information was collected by conducting one-on-one interviews with the siblings. The Siblings' Perceptions of the Intervener Interview (SPII) and Taylor's Siblings' Problems Questionnaire were administered.

The results indicated that individual sibling's perspectives were unique, varying from positive to negative. As a group, the siblings made positive comments about the intervener and their life with their deaf-blind brother or sister.

The Reliance On The Four Major News Agencies For International News Reports In Taiwan, Denise Hsiu-Wen Li

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The purpose of this case study is to figure out the reliance on the four major news agencies (AP, UPI, Reuters, and AFP) for international news reports in Taiwan, and CNA's, Taiwan's only regional news agency, role in supplying international news stories. Taiwan's three large circulation, general purpose newspapers -- United Daily News, China Times, and Central Daily News were selected and analyzed.

The study is based primarily on a content analysis of these three Chinese-language newspapers in terms of their coverage of international happenings and their news coverage.

The findings indicate that the control of international information by the …

Toward A Cultural Interpretation Of The Chinese Restaurant In The Mountain West, Li Li

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The history of Chinese restaurants in the American West shows that Chinese food became a part of the social and cultural realities for Chinese people, especially in the earliest years, partly because regional food helped maintain regional language and dialect. Beyond that, it also demonstrates how restaurants--even more than other service industries such as laundries--provide a living context in which Chinese met non-Chinese, and where the non-Chinese could become acquainted with Chinese art, eating customs, regional cookery, embroidery, and even family life. In other words, the Chinese restaurant became in time a bridge between the two cultures, and has therefore …

Seasonal Movement Patterns Of Coyotes In The Bear River Mountains Of Idaho And Utah, Glen F. Gantz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Coyotes (Canis latrans) prey upon domestic sheep. The Animal Damage Control (ADC) program currently relies heavily on aerial gunning in winter to control coyote depredations on mountain grazing allotments. Some people claim that winter aerial gunning is not effective because coyotes migrate to lower elevations during winter, following herds of big game animals, and may not be on the allotments where summer depredations occur. I studied the seasonal movement patterns of coyotes in the Bear River Range of Utah and Idaho to determine if coyotes in montane habitats move on a seasonal basis. Radio-collared coyotes were located from fixed-wing aircraft …

Immunosuppression By Aflatoxin B1 In C57bl/6 Mice And Its Relationship With Neuroendocrine Mechanisms, Yasuhiko Hatori

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Aflatoxin B₁ (AFB₁), a secondary metabolite of Aspergillus flavus and Aspergillus parasiticus, is known for its potent carcinogenicity and immunosuppressive effects. It is also known that AFB₁ toxicity appears in different degrees in different animal species and strains.

The present study was performed to reveal the involvement of the hypothalamus-pituitary-adrenal gland (HPA) axis in the immunosuppressive effects of AFB₁ on C57BL/6 mice. Splenic lymphocytes were assayed to investigate their phenotyping using flow cytometry, proliferative response against mitogen and allogenic lymphocytes, cytolytic cell activity, and IL-2 production. In addition, antibody-mediated immunocompetence was checked using sheep …

Tourism Dependency And Its Correlation To Selected Socioeconomic Indicators In Utah, Diane S. Gooch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper investigates the relationship between tourism and well being, or quality-of-life, within eighteen counties in Utah. To evaluate the relationship, comparisons of the counties' differing levels of tourism versus their levels of welfare are necessary. To make these comparisons, three basic steps were followed. First, a social ordering model was derived. The proposed social ordering model was based upon Maslow's theory of the hierarchy of human needs. By utilizing his theory, both economic and noneconomic indicators were identified, and a basis was provided upon which to judge the differing positions of well-being. Factor analysis was applied to this model …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous surveys of mental health professionals regarding theoretical orientation and the use of various treatment modalities provided valuable information concerning the nature of mental health delivery but primarily focused on professionals providing services to dominant-culture clientele. The present study focused on those degreed workers whose primary clientele were American Indian. Questionnaires were returned by 140 mental health workers who are American Psychological Association (APA) members of American Indian descent, members of the Society of Indian Psychologists (SIP), employees of the Indian Health Service (IHS), and graduate psychology students. Questionnaire responses were analyzed in terms of orientation and treatment modality for …

The Development And Validation Of A System For The Knowledge-Based Tutoring Of Special Education Rules And Regulations, Mark S. Thornburg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research indicates that school officials fail to identify a relatively high proportion of school-aged children with behavioral or emotional handicaps. As a result, these children may not be receiving the special education services to which they are entitled. Multidisciplinary team members may be failing to identify these children because they lack understanding of special education rules and regulations. The purpose of this project was to combine the technologies of expert systems and mastery-based instruction to develop an inservice and preservice training program capable of producing mastery-level performance of the skills required to identify children with behavioral or emotional handicaps. Borg …

Range livestock operations were inventoried through personal interviews with the owners and herders. Data are supplemented by previous nation-wide and regional survey statistics. Herd productivity data which include herd structures, age, age-related sales, slaughters, gifts, and …

The Effects Of Disease, Prey Fluctuation, And Clear-Cutting On American Marten In Newfoundland, Canada, Richard J. Fredrickson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Individual variation in survival and behavior of American marten (Martes americana) was studied in relation to disease, prey fluctuation, and clear-cutting from 10 January 1986 through 20 August 1987 in Newfoundland, Canada. Thirty-seven of forty marten captured on the study area were telemetered and monitored for part or all of the study.

Marten mortality was concentrated in two intervals, fall 1986 and late winter 1987. Mortality during fall 1986 was attributable to encephalitis, while marten deaths during late winter 1987 resulted from predation and starvation attributable to the prey decline. Nonsuppurative encephalitis was first detected 7 October 1986; …

Substrate Concentration, Calcium Concentration And Κ-Casein Hydrolysis In Milk Coagulation, Fenjin He

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Milk coagulation consists of four overlapping phases: enzymic hydrolysis, micelle aggregation, gelation and syneresis. The objectives of this study were to determine the effects of added CaCl₂ on milk coagulation and the relationship between enzymic hydrolysis and micelle aggregation with substrate at different concentrations.

Addition of CaCl₂ to milk is widely practiced in industry and in laboratories. This changes calcium concentration, pH and ionic strength. It is impossible to separate these three variables and investigate each one independently.

Addition of low levels of CaCl₂ shortens coagulation time and increases curd firming rate. Low levels of CaCl_{2 …}

A Reliability Study On The Self-Report Behavioral Measure For Evaluating Therapeutic Outcome, Sharon B. Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Statement of the Problem

Because the original reliability study using the Self-Report Behavioral Measure for Evaluating Therapeutic Outcomes (Behavioral Checklist) used college students as subjects, and since the target population for use with this instrument is a client population, there is a need for a reliability study using clients in treatment as subjects.

Objective

The objective of this study was to assess the reliability of the Behavioral Checklist using a client population. The secondary objective was to revise the Behavioral Checklist, if necessary, in order to meet the standards of reliability for testing instruments.

Methods and Procedure

Self-Consciousness And Body Image Issues Among College Females, Mary E. Doty

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined some of the procedures used in eating disorder research. Body size estimation procedures, in light of their similarity to procedures in social psychology, were used to create self-focus and self-consciousness conditions. If the procedures in the present study create self-consciousness effects, it is possible that the results of those studies have been affected by a heightened state of self-awareness. The present research also explored the relationships between self-consciousness, self-esteem, body esteem, body perception, and eating disorder proneness.

The research was conducted with a nonclinical sample from a university population, controlling for age and body development factors. Baseline …

The Effects Of Methionyl Bovine Somatotropin Administration On Luteinizing Hormone In Dairy Cattle, Joseph Charles Dalton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sixteen lactating regularly cycling dairy cows (14 primiparous, 2 multiparous) were used to determine the effects of somatotropin administration on basal, peak, and pulse luteinizing hormone concentrations during the breeding period. In addition, the effects of somatotropin administration on the pituitary response to a gonadotropinreleasing hormone challenge was studied. The experimental group received daily somatotropin treatments (25mg) for 24 days. The control group received a daily placebo. All animals were treated with three injections of prostaglandin F2-alpha (25 mgjtreatment) for estrus synchronization. Somatotropin and placebo treatments began with the second prostaglandin injection. Sixty hours following the final prostaglandin injection, all …
