Effects Of Artificial And Pea Aphid Honeydew On Bathyplectes Curculionis (Thomson), A Parasitoid Of The Alfalfa Weevil, Hypera Postica (Gyllenhal), Staci England

Biology

The larval endoparasitoid, Bathyplectes curculionis (Thomson), is a major enemy of the alfalfa weevil, Hypera postica (Gyllenhal), which is the most serious pest of alfalfa in North America. The effectiveness of B. curculionis as a biological control agent may be influenced by the availability of adult food sources. One potential source of carbohydrates, aphid honeydew, has been shown to increase fecundity and longevity in some parasitic Hymenoptera. Pea aphids, Acyrthosiphon pisum (Harris), are often present in Utah alfalfa agricultural systems and their honeydew may act as a food source for B. curculionis. Laboratory experiments were performed to evaluate the …

Meta-Analysis Of Home Visiting Research With Low-Income Families: Client, Intervention, And Outcome Characteristics, Christopher H. Morris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Leaders in the field of home visiting and family support research have indicated that the inclusion of home visiting in comprehensive services for low-income families with young children can play a key role in improving a wide variety of outcomes for at-risk children and their families. These recommendations have been based in part on selected empirical findings from the home visiting literature. However, synthesis of empirical findings has proven difficult, due to the heterogeneity of this population and the diverse applications of home visiting as a service delivery strategy.

The present meta-analysis examined a representative sample of the peer-reviewed literature …

Who's More Cruel, Johnny Or Jenny? Sex Differences In Adults' Perceptions Of Cruelty To Animals By Children, Teresa Michelle Thompson

Undergraduate Honors Capstone Projects

As a symptom of Conduct Disorder, cruelty to animals (DSM IV, 1994) is often assessed via parental checklists (e.g., Child Behavior Checklist). However, little information exists on the criteria that adults use to make judgments of cruelty.

Napoleonic Propaganda: Rationalization For War And Control Of An Empire, Jason S. Abate

Undergraduate Honors Capstone Projects

This paper describes the way Napoleon Bonaparte used propaganda to influence nations to fight the enemies of nineteenth century France and to control the peoples of Europe. Although Napoleon never used the specific term "propaganda" he utilized its methods in order to sway the masses into following him. Under the leadership of Napoleon, France rose from the chaos of revolution to dominate Europe. The armies of France and its allies crushed all opposition militarily, but the political battle for the minds of the people was waged for and by Napoleon.

The Legend Of The Midwife's Blessing, Rosanna West Walker

Undergraduate Honors Capstone Projects

This legend was told by my aunt, Jessie Bradshaw. She was a descendant of Scottish people who settled Wellsville in the 1850s. Her mother, Janet Leatham, died giving birth to another child, and Jessie was reared by my maternal great-great grandmother, Jane Alexander Steele Leatham, who was a midwife. The family members were all devout Mormons.

The Relationship Between Postretirement Activity And Life Satisfaction, Dorothy Jane Gould Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to examine the relationship between the types of activities people engage in after they retire, how often they participate, how or with whom they participate, and how these independent variables influence the dependent variable of life satisfaction. The majority of the research done to date on postretirement activity focuses primarily on recreational activities. This study examined the effects of including some type of substantive or service activity in addition to hobbies and recreational activity. Participants were surveyed concerning their health, mobility, and financial conditions so that these variables could be controlled for in determining …

Assessing Family Strengths Using The Family Profile: Study To Validate And Evaluate Constructs Across Four Models Of Family Functioning, Troy D. Randall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The concurrent criterion-related validity of the Family Profile (FAMPRO) was investigated using the Family Adaptability and Cohesion Scales II (FACES II), the Self-Report Family Inventory (SFI), and the Family Assessment Device (FAD) as criterion measures . Further analysis was conducted through a principal component factor analysis with a varimax rotation and correlations with a Family Satisfaction Scale.

The Family Profile is an easy-to-administer, -score, and -interpret instrument designed for use in family life education. It is a 35-item instrument that measures seven areas of family functioning: Family Fun, Family Decisions, Family Pride, Family Values, Family Caring, Family Communication, and Family …

Issues Of Consensus And Concern: Family Relationships Of The Elderly In The United States And Japan, Takashi Yamamoto

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to explore cultural differences between America and Japan concerning four domains: past family relationships, current family relationships, the support network, and well-being.

Concern and consensus in the family are the principal background issues in this study. In America there has been a change from consensus (sharing basic similarity of values or attitudes and interests) to concern (an intense emotional involvement and affectional closeness). In contrasting the American and Japanese societies, consensus and concern constitute different orders from a more traditional context to the current societal context. This cultural difference impacts the relationship between the …

Noticing Pretreatment Change: Effects On Therapeutic Outcome In Family Therapy, Lee N. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Family therapy, similar to other mental health services, has focused on ways to make therapy brief or short term. One model of family therapy, the brief/solutions therapeutic orientation, claims that certain techniques can reduce the number of sessions. This therapeutic model focuses on the solutions clients bring with them to therapy. By focusing on clients' solutions and not their problems, the brief/solutions orientation claims that clients reach their goals more quickly, finish therapy more quickly, and are more satisfied with the services they receive. However, there is little empirical evidence to support these claims. This research specifically looked at the …

Adolescent Leisure-Time Activity And Problem Behavior: The Integration Of Three Major Explanatory Theories As A New, Gail B. Yost

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Adolescence has in recent decades gained attention as being salient for study of social trends. Increases in youth social problems are seen nationally, statewide, and locally. They include substance abuse, precocious sexual activity, related consequences of pregnancy and STDs, suicide and depression, truancy, running away, crime against property, and violent crime against persons.

This study integrates three major explanatory theories of adolescent behavior into a macro-synthesis. R. Jesser's Problem Behavior Theory emphasizes how problem behaviors do not occur singularly, nor do they justify unique prevention methods. T. Hirschi's Social Control Theory describes how adolescents with little or no attachment to …

Maternal Responsivity To A Child With A Disability: A Comparison In Single- And Two-Parent Families, Kristin Bollwinkel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this research was to examine the differences between mothers in single- and two-parent families as they interact with their child with a disability. The sample consisted of 240 children with developmental disabilities and their mothers. Maternal interaction behaviors were measured using the Maternal Behavior Rating Scale. Demographic information, child characteristic measures, and family functioning variables were also considered. Analyses of covariance indicated that there were no differences between interaction behaviors of mothers in single- and two-parent families. However, relationships between income, education, and family cohesion, and the types of interactions displayed between mother and child were found. …

Child Abuse In The Wake Of Natural Disasters, Thom Curtis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Natural and technological disasters impact thousands of families in the United States each year. Catastrophic events leave homelessness, unemployment, injury, and death in their wake. The cost to society is usually measured in homes destroyed, jobs lost, casualties, and expected dollar expense of recovery. There are the social, psychological, and family consequences of catastrophic stressors. Anecdotal reports suggest that among these consequences is an increase in family violence, including child abuse. This dissertation tests the hypotheses that reported and confirmed child abuse increases in the wake of natural disasters.

The Brigham City Co-Op: Case Study Of An Efficient Economic And Social Institution, Stephen J. Valentine

Undergraduate Honors Capstone Projects

The leaders of the Church of Jesus Christ of Latter-day Saints raced a twin dilemma in the years between 1868 to 1874. The specter of non-Mormon infiltration of society and destruction of the Mormon empire loomed menacingly on the horizon, and internal divisions and inequities threatened to destroy the religious ideals of unity and equality fostered by Mormons since the time of Joseph Smith, Jr. This twin crisis led Mormon leaders to institute church-wide economic and social programs of reform, culminating in 1874 with the establishment of the Second United Order of Enoch.

"Doctors Should Not Participate In Active Physician Assisted Killing", Todd Jorgenson

Undergraduate Honors Capstone Projects

All eyes were on the Oregon ballot this past November 8, as Proposition 16 was introduced to the public. Should the Proposition pass, Oregon would become the first state to legalize physician-assisted suicide. At first glance, the Death with Dignity Act appears to offer the terminally ill patient additional freedom in deciding his or her destiny, but it in fact gives a free license for physicians to prescribe death with little if any scrutiny, responsibility, prosecution and even conscience.

A Functionalist Approach To Emotions, Julien Guillaumot

Undergraduate Honors Capstone Projects

There are at least two ways in which emotions can be conceptualized. The first, and most widespread, one is the cognitive approach which implies the presence of internal processes or psychological mechanisms. The cognitive approach says that emotions are the result of evolutionary processes. The second approach is behaviorological. It states that emotions are learned and are nothing more than behaviorological and physiological events. Both approaches, even if different, have an extremely important effect on our world because they may help make societal decisions and therefore manage our environment in a better way. As we will see, though, authorities do …

Three Practices In Technical Writing: A Portfolio, Alyssa Jean Hambelton

The written narrative that accompanies this portfolio summarizes the …

Socio-Cultural Variations In Interactions: A Study Of Children With Disabilities And Their Mothers, Elina O. Alexandrova

Undergraduate Honors Capstone Projects

This investigation compared interaction behaviors of African-American and European-American mothers with children who had or were at medical risk for disabilities as measured by Maternal Behavior Rating Scale (MBRS; Mahoney, 1992). The relationships between these mothers' interaction ratings and three groups of independent variables (mother/family demographic characteristics, measures of family functioning, and child characteristics) were also examined. T-tests were used to examine the differences between the two groups. Significant differences were found on SES variables, particularly income. Samples were restricted to those with incomes of $32,500 or less. Analysis of covariance procedures were performed using race and family structure as …

The Relationship Among The Contributing Factors To Anorexia Nervosa, Stephanie S. Plunkett, David Stein

Undergraduate Honors Capstone Projects

Anorexia nervosa is now being viewed as a multidimensional disorder in terms of predisposing factors such as genetics, biology, and environment. Results from twin studies suggest that part of a susceptibility to AN may lie in genetic factors (Holland et al., 1984, 1988; Treasure and Holland, 1991). However, the nature of a genetic contribution, if any, remains unclear. Neurochemical alterations have been found to be associated with AN, but it is difficult to assess what role these neurochemical changes play in the etiology of the disorder since they may precipitate, accompany, or follow weight loss (Fava et al., 1989). Abnormal …

Teaching History Through Children's Literature: An Integrated Approach For The Fifth Grade Classroom, Tamara Gayle Crook

Undergraduate Honors Capstone Projects

During my teacher education training I have become fascinated with the idea of teaching social studies through historical novels. As a result of this fascination, I chose curriculum development pertaining to this idea as the subject of my honors project. The purpose of this project was for me to develop, teach, and evaluate an integrated unit using historical novels to teach social studies and a variety of other subjects. I selected the American Revolution as the theme of my unit.

In this paper I have included a brief overview of my review of the literature on this topic, the procedures …

The Impact Of A Mountain Pine Beetle Epidemic On Wildlife Habitat And Communities In Post-Epidemic Stands Of A Lodgepole Pine Forest In Northern Utah, William E. Stone

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Natural disturbance events influence the patterns and processes in many forest ecosystems. Ecosystem management of coniferous forests in western North America requires the recognition of the importance that natural disturbance regimes have in achieving sustainable resource production and maintaining biological diversity . Mountain pine beetle epidemics have played an historic role in the succession and structure of lodgepole pine forests in this region. Their effects on wildlife habitat and communities are undocumented, but are presumed to be substantial. I sought to quantify these effects in forty 1-ha stands of monotypic, even-aged, mature lodgepole pine forest in northern Utah approximately 3-8 …

The Relationship Between Depression And Anxiety, And The Personality Traits Of Dependency And Self-Criticism, Douglas E. Craig

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationships between depression and the traits of dependency and self-criticism are well documented in the research literature. However, relatively few studies have investigated anxiety in relation to the two traits. The purpose of this study was to examine the relationship each trait has with general anxiety and with social anxiety. Also, because depression and anxiety overlap, a multivariate analysis examined the relationships among the trait and mood constructs while accounting for the overlap between constructs. Subjects completed the Depressive Experiences Questionnaire (assessing dependency and self-criticism), the Beck Depression Inventory, the State-Trait Anxiety Inventory, and the Fear of Negative Evaluation …

Metabolism Of Selected Antiviral Agents In Cells Infected With Drug-Resistant And Wild-Type Strains Of Murine Cytomegalovirus, Kevin M. Okleberry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Resistance of human viral pathogens to various antiviral drugs is a serious medical problem. Two modes of drug resistance in cytomegalovirus infections have been observed, the first being altered (decreased) drug metabolism by the infected cells, and the second reduced sensitivity of the viral deoxyribonucleic acid polymerase enzyme to the active form of the drug. Mice infected with the murine cytomegalovirus have been used extensively as an animal model for the human cytomegalovirus, and drug-resistant strains in this model have been identified. To better understand the mode of drug resistance of the virus, the metabolism of two antiviral drugs, 9-(1,3-dihydroxy-2-propoxymethyl)guanine …

Alteration Of Key Cytokine Levels By Aflatoxin B1 And T-2 Toxin In Male Cd-1 Mice, Raviprakash R. Dugyala

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Aflatoxin B₁ and T-2 toxin are mycotoxins, which produce their immunotoxic effects by affecting nonspecific and acquired immunity in different species. The mechanisms of their immunotoxicity are still obscure. Cytokines are the key signaling molecules during the immune response. In this study, expression of macrophage-produced cytokines Interleukin-lα (IL-lα), tumor necrosis factor (TNF), and IL-6, and lymphocyte-produced cytokines IL-2, interferon y (IFNy), and IL-3 was measured at the mRNA and protein levels, after in vitro activation with mitogens in AFB₁-and T-2-toxin-exposed mice.

Significant changes in the organ weights, especially in the mice exposed to a high dose of …

Evaluation Of Milk Production In Western Whiteface And Navajo-Churro Ewes, Marla Faye Brindley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Western Whiteface and Navajo-Churro Ewes, two types of sheep present in the Intermountain West, were compared for their milk production ability. Amount of milk produced per individual and the group milk composition were analyzed for butterfat, lactose, somatic cell count, protein, calcium, and phosphorous.

Ewes were fed ad libitum alfalfa hay and had access to free-choice grain while in the milking parlor. Lambs were weaned at 35 d of age and removed to another holding area and placed on creep feed . Ewes were milked for 90 d following the weaning of the lambs.

Western Whiteface ewes had a much …

The Effects Of Feeding Chelated Metal Proteinates On Milk Production And Reproductive Performance In Holstein Dairy Cows, Ben James Hardcastle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Twenty-two primiparous Holstein heifers were allocated to one of two treatments. Treatments consisted of: 1) basal ration plus 226.8 g inorganic mineral supplement (control); and 2) basal ration plus 226.8 g inorganic mineral and metal proteinate supplement (50:50). Individual heifer performance was measured during the final 10 weeks of the prepartum period. Feed intake and refusals were recorded daily. Individual heifer body weights recorded weekly did not differ significantly. Blood samples taken at 4-week intervals did not differ in plasma concentration between treatments. Calf birth weights for control heifers were not significantly higher than calves from the treatment heifers.

Use Of Recombinant Human Granulocyte Colony Stimulating Factor As An Adjunct In Antifungal Chemotherapy In Various Animal Model Systems, Lindi Farrell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The growing neutropenic patient population provides an ideal target for opportunistic fungal infections. Several effective antifungal drugs are toxic at high doses and contraindicated for long-term treatment. Recombinant human granulocyte colony stimulating factor (rhG-CSF) has been shown to increase neutrophilic numbers and functions, thus providing enhanced host defense. Improved efficacy by using rhG-CSF in conjunction with various antifungal agents was the primary focus of these studies. Use of rhG-CSF in a murine model of vaginal candidiasis did not reduce vaginal colony counts, or improve vaginal histophathology scores. Administration of rhG-CSF in a murine model of pulmonary aspergillosis improved survival, clinical …

Effects Of Antioxidants On Development Of In Vitro Fertilized Bovine Embryos, Bret L. Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Free radicals are short-lived molecules that can cause decreased embryonic development in vitro. Antioxidants are molecules that block free radical formation or guard against their harmful effects. Many studies have linked exposure of media to light and culturing of embryos in high (20%) oxygen concentrations to free radical production. Some of the antioxidants used in culture media are superoxide dismutase (SOD), catalase, zinc (II), ethylenedinitrilo tetraacetic acid (EDTA), mannitol, vitamin E, dimethyl sulfide, and taurine. Most research involving antioxidants and embryonic development has been conducted on non-farm animals, particularly mouse and rabbit. Studies have shown that antioxidants in vitro culture …

A Psychometric Evaluation Of Five Commonly Used Measures Of Family Functioning And How They Correlate With Development Of Children With Disabilities, Matthew J. Taylor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In response to the increased emphasis in early intervention on assessing family functioning, there has been substantial effort over the past 15 years to develop instruments that can measure important aspects of family functioning with families of children with disabilities. While the multitude of recently developed family measures has given researchers and clinicians a variety of instruments from which to choose, research on the quality of the data derived from these instruments has lagged behind. Considering the importance of family functioning in current early intervention programs and the potential impact on the type of intervention delivered, further investigation of the …
