The Effect Of High Elevation Weather Stations On The Usda's Pasture, Rangeland, And Forage Insurance Program, Wyatt Matthew Feuz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper examines the effect of high elevation weather stations on the rainfall index used by the Pasture, Rangeland, and Forage insurance program. Weather station data for the state of Utah is used to identify high elevation weather stations and their location. Utilizing the corresponding rainfall index data, the effect of the high elevation weather stations is determined. This paper finds when high elevation weather stations begin reporting there is a jump up of 19.01–27.88 percentage points on average in the rainfall index for the corresponding grid locations. This indicates the rainfall index may not accurately represent actual precipitation amounts …

Collaboration And Reflexivity In Wildland Fire Risk Governance In The Western United States, Brett Alan Miller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation presents both quantitative and qualitative analysis on different aspects of wildland fire risk management in the western United States. Each of these chapters is framed by and examines the sociological concept of reflexivity, which describes a process of individual and/or collective reflection. This reflexivity is needed to identify and enact alternative management strategies that contend with the expected increases in the number and severity of wildland fires in the future due to the combined effects of even-aged forest growth after years of timber extraction, a legacy of fire suppression, climate change, and increasing human development in the wildland-urban …

Using Anthropogenic Risks To Inform Salmonid Conservation At The Landscape Scale, Andrew W. Witt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The expansion and industrialization of humanity has caused many unforeseen consequences to the natural world. Due to the importance of freshwater for people, rivers have been particularly altered to meet human needs, often at the expense of the natural world. Supplying water for farms, industries, and cities has reshaped the natural state of rivers by altering river paths, chemistry, and species compositions. These changes have harmed many species that prospered before widespread human alterations, including the native trout and salmon of western North America. As human populations continue to grow, new threats will surface for rivers, and the trout and …

Humans As Sensors: The Influence Of Extreme Heat Vulnerability Factors On Risk Perceptions Across The Contiguous United States, Forrest Scott Schoessow

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Extreme heat events are the deadliest natural hazard in the United States and will continue to get worse in the coming years due to the effects of climate change. As a result, more people will experience deadly heat conditions. This highlights the need for decision-makers to develop better strategies for preventing future losses. How badly individuals are affected by extreme heat depends on many circumstances, such as how high temperatures actually are, weather conditions, and location. For example, a dry 90 °F day in Phoenix is probably more tolerable than a humid 90 °F day in New Orleans for most …

The Mental Health Disparity Among Nonheterosexuals: Risk, Resiliency, And New Perspectives To Consider In The Context Of Mormonism, Katherine Ann Crowell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nonheterosexuals disproportionately experience mental illness when compared with heterosexuals. Although it has been well established that the apparent mental health disparity among sexually diverse populations is almost exclusively derived from minority stress (i.e., the excess stress associated with culturally maintained sexual stigma), our understanding of how specific aspects of minority stress lead to specific psychological syndromes (e.g., depression) remains limited. On the other hand, in attempts to destigmatize individuals who do not identify as heterosexual, researchers have increasingly begun to shift the focus of their work towards understanding the specific characteristics or experiences that facilitate individuals’ capacity to adapt and …

Decision Making Using Trust And Risk In Self-Adaptive Agent Organization, Kamilia Ahmadi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Interaction between agents is one of the key factors in multi-agent societies in order to cooperatively execute complex tasks which are beyond the capability of a single agent. In the self-adaptation society, agents try to keep best neighbors around themselves. Agents use history of past iterations to evaluate their neighbors and locally modify their structural links. Main characteristics of this model are its decentralization, dynamicity and no need of external control. This research at first deals with implementing self-adaptive agent organization. Then it focuses on evaluating cooperation peers in decision making. Trust as an evaluation mechanism lies at the core …

Risk And Climate At High Elevation: A Z-Score Model Case Study For Prehistoric Human Occupation Of Wyoming's Wind River Range, Ashley K. Losey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Holocene climate likely influenced prehistoric hunter-gatherer subsistence and mobility as changing climate patterns affected food resources. Of interest here is whether climate-driven resource variability influenced peoples in the central Rocky Mountains. This study employed the z-score model to predict how foragers coped with resource variability. The exercise enabled exploration of the relationship between climate, resources, and foraging strategies at High Rise Village (48FR5891), an alpine residential site in Wyoming's Wind River Range occupied between 2800-250 cal B.P. The test was applied to occupations dating to the Medieval Warm Period (1150-550 cal B.P.) and the Little Ice Age (550-100 cal B.P.). …

Newlywed To Established Marriage: A Longitudinal Study Of Early Risk And Protective Factors That Influence Marital Satisfaction, Daniel Alfred Moen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This current study took questionnaire information from couples as newlyweds through five years of marriage in an attempt to discover the most significant predictors of marital satisfaction.

This study also used additional information from these couples to help understand how problem issues change from newlywed to established marriage (five or more years of marriage). This study found that experiencing a difficult transition to marriage as newlyweds was the only significant predictor of marriage satisfaction five years later. Meaning, couples who experienced a difficult transition to marriage as newlyweds tended to report lower levels of marital satisfaction five years later in …

The Comparison Of Five Different Cattle Feeding Enterprises: A Stochastic Simulation On Expected Returns And The Effects Of Lrp Insurance, Caleb H. Bott

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This was a study on the Utah cattle industry which compared five different feeding enterprises. These feeding enterprises included feeding cull cows, finishing beef yearling steers, finishing Holstein yearling steers, backgrounding beef steer calves, and backgrounding Holstein steer calves. The main purpose of this study was to determine which feeding enterprise was the most profitable for Utah cattle producers.

Another objective of the study was to determine if LRP insurance lowered the volatility in the returns to these feeding enterprises. In order to answer these two questions of interest, a historical analysis of Utah cattle and feed prices was conducted …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this research is to provide quantitative and limited qualitative analysis for the United States Intermountain West on the economic effectiveness of risk management alternatives in an agricultural operation. This research is not meant to be an exhaustive comparison of every potential combination of alternatives and risk scenarios. Instead, specific parameters such as farm size, crops grown, risk attitudes and risk management strategies are set to guide the research and offer a basis of comparison.

This research evaluates several levels of coverage using Multiple Peril Crop Insurance, Crop Revenue Coverage Insurance, Adjusted Gross Revenue – Lite Insurance and …

Turning Points And Protective Processes: A Qualitative Study On Resilient Youth Through Their Perspective As Resilient Adults, Michael E. Monson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study investigates the processes of resiliency and the turning points of decision-making in youth from at-risk environments. The study utilizes a constructivist, qualitative approach, to examine indicators of resiliency from both an individual and contextual perspective. The narrative descriptions of eleven adults from at-risk childhoods are analyzed through biographical interviews.

Analyses were completed to determine common factors that contribute to the process of resiliency in successful adults. Results indicate that the influences of risk on healthy functioning are modified by shifting environmental protective factors, resources, and developed attributes of self-efficacy. Risk and adversity had a strengthening effect that contributed …

Type 2 Diabetes And The Risk Of Osteoporotic Hip Fracture In Utah Men And Women, Megan Bunch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Prior studies have unequivocally established a consistent association between osteoporotic hip fracture risk and type 2 diabetes mellitus. One reason this association still remains unclear is primarily due to the limited amount of research conducted in this area. The Utah Study of Nutrition and Bone Health (USNBH) is a case-control study conducted in Utah during the period of 1997-2001 to determine risk factors for osteoporotic hip fracture. All study participants (n = 2590) were determined from Utah residents 50-90 years of age. Cases were determined from 18 Utah hospitals during 1997-2001. Age and gender-matched controls were randomly selected from the …

Milk Intake In Early And Late Adulthood And Risk Of Osteoporotic Hip Fractures In Utah, Melanie Jean Slavens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationship between milk intake and risk of osteoporotic fractures is uncertain. Associations between milk intake and milk avoidance in relation to osteoporotic hip fracture were examined in the Utah Study of Nutrition and Bone Health (USNBH), a statewide case-control study. Cases were ascertained at Utah hospitals treating 98 percent of hip fractures during 1997-2001 and included 1188 men and women aged 50-89 years. Age- and gender-matched controls were randomly selected from Utah driver's license and Medicare databases (N= 1324). In-person interviews were conducted and participants reported frequency of milk intake per week at age 18 and during pregnancy among …

Smoking, Anemia, And Risk Of Oral Clefts In Utah, Melinda Michelle Moss

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cigarette smoke contains sufficient carbon monoxide to induce maternal and fetal hypoxia. Hypoxia is a known teratogen, and consequently maternal smoking has been the focus of many studies on adverse birth outcomes, including cleft lip and palate. Current literature of epidemiological studies on smoking and clefts suggests a modest but statistically significant increase in risk of clefting associated with maternal smoking. A biological condition that may also contribute to hypoxia is anemia. Data from the Utah Child and Family Health Study was used to assess the effects of hypoxia-inducing conditions, maternal smoking, anemia, and their interaction, on the risk of …

Examination Of The Ecological Differences Between Two Closely Related Endemic Whitefish In Relation To Growth Conditions And Predation Risk, Benjamen M. Kennedy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Benthic Bear Lake whitefish (Prosopium abyssicola) and Bonneville whitefish (P. spilontus) are closely related, yet the extent of ecological separation remains poorly understood. We described their spring and summer distribution and diet in Bear Lake and examined how these were related to environmental growth conditions, and predation risk. In spring and summer, Bonneville whitefish dominated shallower depths (5-30 m), whereas Bear Lake whitefish dominated deeper depths (45-55 m). At intermediate depths (35-40 m), low numbers of both species occurred. Bonneville whitefish ate mostly Chironomidae, whereas Bear Lake whitefish ate mostly Ostracoda. Habitats occupied by Bonneville whitefish …

Multiple Mentors And Family Involvement In Mentoring At-Risk Youth, Christine W. Woodbury

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined whether higher family involvement plus additional mentoring relationships had a greater positive effect than a one-on-one relationship with a mentor and low family involvement. The study demonstrated, in this sample, that having two mentors does not have a greater impact on academic motivation, social competency, family unity, self-esteem, and deviance than having one mentor. It was also shown, in this sample, that higher family involvement does not have a greater impact on academic motivation, social competency, family unity, self-esteem, and deviance than lower family involvement. Although additional studies are needed to fully understand the impacts of mentoring …

Voluntary And Involuntary Weight Change And Risk Of Osteoporotic Hip Fracture In Men And Women Of Utah, Megan Ruth Mcdonough

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Change in body weight is an important determinant of risk of osteoporotic hip fracture in aging adults. Weight loss has been associated with an increased risk of hip fracture and weight gain has been associated with a decreased risk of hip fracture. Weight gain cannot be recommended as appropriate prevention against hip fracture, however, because it is associated with such adverse health outcomes as cardiovascular disease and diabetes, and weight loss is commonly recommended in the treatment of these types of diseases. Clarification of how weight loss is related to risk of hip fracture is needed to resolve this issue. …

Using A Classwide Peer-Assisted Self-Management Program To Improve Classroom Behavior Of Secondary-Age At-Risk Students, Katherine J. Mitchem

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Classroom management is still one of the top-rated concerns of general educators and public school administrators, even though there exist a number of empirically supported interventions that improve classroom behavior. The current research, consisting of two studies, examined the effectiveness, feasibility, and acceptability of one of these interventions, a classwide peer-assisted, self-management program. Using a multiple baseline design across classes, the first study investigated the effects of the Peer-Assisted Learning (PAL) Game on appropriate classroom behavior of three classes of seventh-grade language arts students and of 10 target at-risk students. The PAL Game consisted of teacher instruction in self-management and …

Risk Factors And Bulimia Outcomes In Adolescent Women: A Longitudinal And Retrospective Analysis, Therese Elizabeth Barnett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The goal of the present study was to verify whether four purported risk factors predate the development of eating disorder symptoms, particularly bulimia nervosa. The four major purported risk factors for developing bulimia nervosa (and eating disorders in general) among female adolescents include: (a) over internalization of culture’s value of thinness in women, (b) inordinate dissatisfaction with body form, (c) depression, and (d) irrational beliefs and cognitions about thinness and the benefits of dieting. The present study involved a 5-year follow-up of adolescent girls initially identified as being either at high or low risk for developing an eating disorder, particularly …

Relation Between Child Abuse Risk And Security Of Mother-Infant Attachment At One Year, Miriam Egan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although previous studies have shown that children who have been abused are more likely to be classified as insecurely attached to their mothers, research has not examined risk for child abuse when measured as a continuous variable in relation to security of attachment when measured as a continuous variable. This study examined the relation between risk of child abuse (as measured by the Child Abuse Potential Inventory and the Harsh Parenting Scale) and security of mother-infant attachment (as measured by the Q-sort of Infant Attachment) at 14 and 17 months. Results supported the view that there is a negative relation …

The Effects Of Parental Involvement With Preschoolers At Risk For Developmental And Behavioral Problems, Robin Skoien-Bradley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parental involvement 1n early childhood intervention with children at risk has been reported as an effective variable in treatment both in popular literature and research reviews. However, the results of meta-analyses of early intervention literature have concluded that research evidence is not currently available to support this notion. Therefore, research which employs strong methodology to study the efficacy of parental involvement in early interventions with children at risk is needed. The purpose of this study was to determine whether, in a sample of preschoolers exhibiting developmental and behavioral risk, there are posttreatment differences between different levels of parent-involved groups in …

Risk In Production, Mamadou Dian Diallo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Most production activities undertaken involve a certain degree of risk. Agricultural production is particularly risky since it is susceptible to the physical vagaries of nature and all economic and social variations. For most countries, agriculture is an important and vital sector where production decisions are made under risk. Hence, decision making under risk requires careful analysis and represents an important area of study.

The present research has been directed to advance our knowledge about the consequences of risk, and the behavior toward risk in the organization of production, particularly agricultural production. This objective is achieved by a review of risk …

Primary Prevention Of Child Abuse And Neglect: Identification Of High Risk Adolescents Prior To Parenthood, Stephen John Bavolek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of the study was to develop a valid and reliable instrument designed to assess the parenting and child rearing attitudes of adolescents, Responses to the instrument would allow for the identification of "high risk" adolescents, i.e., those adolescents whose attitudes towards parenting and child rearing indicated a high potential for child abuse.

A review of the literature identified the following four parenting constructs most commonly associated with abusive parents: Construct A: Inappropriate parental expectations of the child; Construct B: Inability of the parent to be empathically aware of the child's needs; Construct C: Strong parental belief in the …
