Perceptions And Use: A Survey Of Visitors In The Lakes Management Area, Kamas Ranger District, Wasatch-Cache National Forest, Utah, Ronald E. Vance

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

New planning and management paradigms for the USDA Forest Service suggest that future Forest Plans incorporate the best available science and the public's values into Forest Plan revisions. Revised plans should focus on the ecological capabilities of the land and how to sustain them. The means to manage the land for these outcomes should be developed with considerable and ongoing public involvement. One outcome of this public involvement can be the development of a "desired future condition" for the area being managed and the needed regulations to maintain and monitor the desired conditions.

In order to provide preliminary information on …


Criterion-Related Validity Of The Borg Ratings Of Perceived Exertion (Rpe) Scale : A Meta-Analysis, Michael J. Chen May 1998

Criterion-Related Validity Of The Borg Ratings Of Perceived Exertion (Rpe) Scale : A Meta-Analysis, Michael J. Chen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Borg Ratings of Perceived Exertion (RPE) Scale has proven to be a highly popular instrument in measuring the subjective responses of individuals to a given work or exercise task. Historically, the instrument was designed to correlate highly with the heart rates in young-to-middle-aged men performing various tasks. The body of literature, however, has revealed inconsistencies in the extent of just how strong the relationship is between ratings of perceived exertion and various physiological criterion variables, most notably, heart rate. In addition, most studies have invoked the question of whether the criterion-related validity coefficients derived from the relationship between ratings …

Preschool Children's Expectations For Parental Discipline, Angie Geertsen Graham May 1998

Preschool Children's Expectations For Parental Discipline, Angie Geertsen Graham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many factors influence preschool children's expectations for parental discipline. Parent characteristics such as personality, values, social class, and disciplinary methods can affect the expectations children have for parental discipline. Children's ability to understand and interpret parental messages can also influence how they will respond. All of these factors need to be taken into consideration in order for effective communication between parents and children to occur.

In this study, preschool children's expectations for parental discipline were examined by using puppets to reenact three different types of disciplinary situations: prudent, moral, and social-conventional. Children, acting as their mother, used puppets to role …

The success of the programs has been assessed by examining recidivistic activity as measured by post-treatment criminal histories. The results of this study indicate that the sample of clients departing from treatment in Utah in the year 1995 has a recidivism rate of93.2% for sexual criminal behavior, as of …


Therapy Videotape Presentation For Eating Disorder Clients: Development And Evaluation, Benita J. Quakenbush May 1998

Therapy Videotape Presentation For Eating Disorder Clients: Development And Evaluation, Benita J. Quakenbush

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Eating disorder clients show low motivation, poor follow-through, and inordinate premature dropout rates in treatment. Earlier studies support the use of pretherapy training to help clients understand the tasks and challenges of therapy. However, a pretherapy intervention, such as showing prospective clients a video that outlines recovery issues and themes, had not yet been developed specifically for the prevalent, recalcitrant problem of eating disorders. Thus, of particular interest to clinicians who treat eating disorders may be the development of a theoretically sound, pretherapy videotape that outlines recovery issues.

One of the purposes of this study was to review prior investigations …

Analogical Problem Solving: The Differential Impact Of Type Of Training, Amount Of Practice, And Type Of Analogy On Spontaneous Transfer, Dune E. Ives May 1998

Analogical Problem Solving: The Differential Impact Of Type Of Training, Amount Of Practice, And Type Of Analogy On Spontaneous Transfer, Dune E. Ives

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research on analogical problem solving has delineated several factors that impact one's ability to spontaneously generate a correct solution strategy to a target problem. These factors include, but are not limited to, type of analogy provided to subjects (i.e., partial versus complete), the level of analogical problem-solving expertise, and the absence of or type of analogical problem-solving training (i.e., teacher-generated or learner-generated) provided to learners.

Recently, researchers have begun to focus on providing solvers with multiple practice opportunities and extending these opportunities over a systematically distributed period of time. When combined with analogical problem-solving training, these factors will augment the …


An Evaluation Study Of Site-Based Managed Behaviors In A Rural Utah School, Barbara R. S. Soriano May 1998

An Evaluation Study Of Site-Based Managed Behaviors In A Rural Utah School, Barbara R. S. Soriano

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Site-based management (SBM) in schools can trace its roots back to two phenomena, citizen's movements in large cities such as New York in the late 1960s and decentralization efforts of business in the 1970s. Both were done in the belief that achieving a better result can be done 11 through decisions made by the people closest to the process. Site-based management programs are diverse. Some stress one aspect, the restructuring of the school administration and program to affect achievement. Other schools stress a second aspect, the empowerment of teachers and stakeholders to make administrative decisions.

Whichever emphasis chosen, several changes …


Assessing Mental Health Of Native American Children: Relationship Of Acculturation With Social, Emotional, And Behavioral Functioning, Christopher H. Morris May 1998

Assessing Mental Health Of Native American Children: Relationship Of Acculturation With Social, Emotional, And Behavioral Functioning, Christopher H. Morris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The literature indicates that, in comparison to children of other ethnic minority groups, Native American children may be at greater risk for a variety of emotional and behavioral Ill disorders and negative psychosocial conditions. Many may also struggle to resolve issues related to cultural identity. Understanding how Native American children and families relate to the cultures within which they live is a critical aspect of preventing and treating childhood mental disorders. Although Native children and families face persistent social pressure to adapt to a multicultural world, no systematic research exists examining the relationship between families' experience of acculturation and their …

The Nonuse Of Figurative Language In Conduct Disordered Adolescents, Mike Berger May 1998

The Nonuse Of Figurative Language In Conduct Disordered Adolescents, Mike Berger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationship between the literal language and conduct problems among conduct disordered adolescents was examined in 109 subjects. The inability to use figurative language was found to be positively related to ratings of conduct problems. Both the parents' discipline style and nonuse of figurative language were related to conduct problems in conduct disordered adolescents. The possible role of other variables, for example, age, sex, and IQ, was examined. Possible mechanisms that could relate the lack of figurative competence and conduct problems were explored.


Characteristics Of Internalizing Social-Emotional Behaviors Of Southwestern Native American Children, Carolyn Thomas Morris May 1998

Characteristics Of Internalizing Social-Emotional Behaviors Of Southwestern Native American Children, Carolyn Thomas Morris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The knowledge base targeting internalizing symptomatology in Native American children is surprisingly limited. As yet, it is not clear if the process and symptoms of internalizing disorders are the same across cultures. The need for further investigation is heightened by the fact that, compared to the majority population, Native Americans are believed to be at greater risk for psychological problems because of impoverished conditions, high unemployment, and high numbers of traumatic events on the reservations. Additionally, the losses of traditional culture and language are considered risk factors for greater psychopathology. The negative ramifications of internalizing disorders (e.g., depression and anxiety) …

Influence Of Stress Treatments On The Resistance Of Lactococcus Lactis To Freezing And Freeze-Drying, Chan Lin May 1998

Influence Of Stress Treatments On The Resistance Of Lactococcus Lactis To Freezing And Freeze-Drying, Chan Lin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study investigated the effect of cold, heat, or osmotic shock treatment on the resistance of L. lactis subsp. cremoris MM160 and MM310 and Lactococcus lactis subsp. lactis MM210 and FG2 cheese starter bacteria to freezing and freeze-drying. The ability to withstand freezing at -60°C for 24 h was variable among lactococci, but resistance to this treatment was significantly improved (P < 0.05) in most strains by a 2-h cold shock at l0°C or a 25-min heat shock at 39°C (L. lactis subsp. cremoris) or 42°C (L. lactis subsp. lactis). Stress treatments that improved lactococcal freeze resistance were also found to significantly (P < 0.05) enhance the resistance of most strains to lyophilization. Increased resistance to freezing or lyophilization was not detected when stress treatments were performed in broth that contained erythromycin, which indicated stress-inducible proteins were involved in cell protection. Membrane fatty acid analysis of stress-treated cells suggested that enhanced resistance to freezing and lyophilization may be related to heat or cold shock-induced changes in cell membrane composition. Heat-shocked cells had a higher 19:0 cyclopropane fatty acid content than did control cells, and cold-shocked cells contained a lower ratio of saturated to unsaturated fatty acids. Other factors must also be involved in cell protection, however, because similar changes in membrane composition were also detected in strains whose resistance to freezing and lyophilization was not improved by heat or cold shock.
