UNLV Theses, Dissertations, Professional Papers, and Capstones

The present research proposed a definition and a theoretical model of health motivation that consists of four stages: development of health motivation tendency, formation of health intention, initiation of health related action, and persistence in actions to achieve goals developed at the first stage. Based upon this model, two health motivation scales - the Health Motivation Scale in Physical Activities (HMS-PA) and Health Motivation Scale in Healthy Eating (HMS-HE) were developed. Two studies were conducted to validate the validity of the scores obtained by these two scales. Study 1 proposed a definition and a theoretical model of health motivation, as …

The Meaning Of Being A Primary Nurse Preceptor For Newly Graduated Nurses, Jennifer Richards

UNLV Theses, Dissertations, Professional Papers, and Capstones

Preceptorship is a vital component of the transition experience of newly graduated nurses into clinical practice. Preceptors teach, supervise, and evaluate newly graduated nurses, and also help them socialize into their roles as registered nurses. In the presence of an ever-growing nursing shortage and evidence that many new nurses are leaving their first positions, it is of paramount importance that we make every attempt to ease the transition of newly graduated nurses into clinical practice. Additionally important is the need to understand the experience of all involved in the process.

The primary purpose of this study was to achieve a …

Evaluating The Response Styles Theory Of Depression Using Descriptive Experience Sampling, Theresa A. Scott

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Response Styles Theory of Depression states that there are two main responses to depression: distraction and rumination. Though it is believed distraction helps to alleviate feelings of dysphoria, the theory suggests rumination actually prolongs and intensifies episodes of depression (Nolen-Hoeksema, 1990, 1991). Rumination is also believed to play a role in the higher rates of depression seen in women (Nolen-Hoeksema, 1990, 1991). In 1987, Nolen-Hoeksema created the Response Styles Questionnaire (RSQ) as a measure to identify those who tend to use distraction or rumination as a psychological response to feelings of sadness or depression. The goal of this study …

Mental Illness, Co-Occurring Factors And Aggression As Examined In An American Prison, Stephanie Leigh Sullivan

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study examines the relationship between several factors which have been identified in previous research as co-occurring and risk relevant to aggressive behavior. Although many factors have been addressed independently for various reasons in other studies, this study looks at the unique combination of a select few of these variables and their relationship for propensity towards aggression. The results of this study show propensity towards aggression is significant for two specific mental health issues; anxiety, and history of severe head injury. Results also indicate that co-occurring factors are prevalent in this sample and those inmates with prior mental illness are …

Patient-Focused Research: Examining The Psychotherapist As A Feedback Receiver, Michael Haderlie

UNLV Theses, Dissertations, Professional Papers, and Capstones

The provision of feedback to psychotherapists regarding patient progress has been shown to produce improved therapy outcomes. However, little is known regarding therapists' responses to feedback. The current research examined novice therapists' perceptions of feedback based on the Outcome Questionnaire-45 (OQ-45). It was hypothesized that feedback would be considered more valuable when it was negatively-valenced (i.e., indicated that patient response to therapy was worse than expected). Patients (N = 19) of 5 trainee psychotherapists completed the OQ-45 before each session. Therapists then received feedback and rated it based on several characteristics. As hypothesized, negatively-valenced feedback was rated as more valuable …

From School To Practice: The Meaning Of Nurses' Holistic Comfort, Michal Goodwin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Nurses entering the healthcare arena are likely to encounter a gap in preparation from school to practice. Despite well-intentioned transition programs, nurses struggle to keep up with the reality of demanding schedules, stressful work environments and non-nursing tasks, such as their own comfort. Holistic comfort, a well-known concept in patient care, offers an innovative approach to nursing education to sustain new nurses transitioning into practice. This phenomenological study explored how nurses who experienced holistic comfort in their schooling were able to use the same philosophical approach to transcend unavoidable difficulties early in their careers.

Newly practicing nurses from a program …

Biofeedback Assisted Relaxation Training Program To Decrease Test Anxiety In Nursing Students, Catherine Andrea Prato

UNLV Theses, Dissertations, Professional Papers, and Capstones

Nursing programs have been cited as being among the most stressful undergraduate programs. Students' knowledge and skills are consistently tested and monitored, and students may fail a course or be dropped from their nursing program if scores are not above a certain standard. Anxiety reactions are common to situations perceived as threatening; however, excessive anxiety may paralyze an individual and interfere with effective learning, functioning, and testing. Numerous studies have found increased anxiety causes physiological changes including increased respirations and heart rate, and decreased peripheral skin temperature. The purpose of this study was two fold. First test anxiety was measured …

Child Neglect And Trauma: The Additive Traumatic Effects Of Neglect On Maltreated Adolescents, Adrianna Rachel Wechsler

UNLV Theses, Dissertations, Professional Papers, and Capstones

Child maltreatment affects thousands of youths in the United States and poses numerous detrimental effects to individuals, families, and the community. Neglect is the most commonly reported and least studied form of child maltreatment. All types of child maltreatment may result in negative outcomes, but the chronic and pervasive nature of child neglect poses a significant threat to child development. No studies have been published evaluating the role of child neglect in the development of Posttraumatic Stress Disorder (PTSD) and PTSD-related symptoms. This study examined whether neglect has an additive traumatic effect on maltreated youth. The first hypothesis was that …

When Did The Ancestors Of Polynesia Begin To Migrate To Polynesia? The Mtdna Evidence, David Lesniewski

UNLV Theses, Dissertations, Professional Papers, and Capstones

The timing and nature of the migration of the ancestors of the Polynesian people is debated by two competing theories. The "Express Train" and "Slow Boat" theories assert that the migration of the Proto-Polynesian people began around 6,000 years before present (BP) or around 10,000 years BP respectively. Through the use of haplogroups and specific genetic mutations a direct relationship between the Proto-Polynesians and modern Polynesians was attempted to test which of these theories was correct. The ancient skeletal remains from the island of Borneo currently housed at UNLV were used in this study as their dates fall within both …

Neurocognitive Deficits And Functional Outcome In Bipolar Disorder, Danielle T. Bello

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bipolar disorder affects approximately 1% of the population. It is a severe and debilitating illness, causing serious impairment of interpersonal, occupational and social functioning. The disorder is characterized by marked mood swings as well significant neurocognitive deficits. Based on work with other psychiatric and neurological disorders, neurocognitive deficits in bipolar disorder are expected to be strong predictors of functional capacity. However, few studies have evaluated the consequences of neurocognitive deficits in this disorder. Most available studies have focused on the clinical correlates of functional outcome, such as number of hospitalizations, age of disorder onset, and severity of symptoms. While useful, …

Job Satisfaction Comparison Between Foreign Educated Nurses And U.S. Educated Nurses, Kari Zizzo

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current nursing shortage has impacted the profession and resulted in desperate recruitment of immigrant nurses to work in the U.S. Low job satisfaction is a factor implicated for the high nurse turnover rates, which contributes to further shortages and recruitment. Satisfaction amongst all nurses has been assessed in past research to address these issues; however no research per se has compared job satisfaction of nurses who obtained their nursing education in the U.S. to nurses who obtained education in other countries. It was the purpose of this study to compare these groups to identify any differences in job satisfaction. …

The Efficacy Of Fragrance Use For Enhancing The Slot Machine Gaming Experience Of Casino Patrons, Gael D. Hancock

UNLV Theses, Dissertations, Professional Papers, and Capstones

Once guests are inside a casino, experiential factors within the casino must be managed so that these guests are encouraged to engage in the gaming opportunities; remain in the casino to eat and shop; return to the casino; and hopefully, to recommend the casino to others. Ambient conditions have been shown to influence a person's willingness to stay in a public setting and their repatronage intentions. Air fragrance is one small, but controllable piece of the experience puzzle that includes décor, lighting, music and other ambient sounds, comfort of the seating, quality of the service, perception of cleanliness and ease …

Exploring The Effects Of Online Instruction On Reading Comprehension Achievement Of Students With Learning Disabilities, Nancy Shuman Fitzgerald

UNLV Theses, Dissertations, Professional Papers, and Capstones

Two major pieces of legislation, the Individuals with Disabilities Education Act (2004) and No Child Left Behind (NCLB) (2001) mandate that students with disabilities be placed in the Least Restrictive Environment and have access to the general education curriculum. To provide access to the general education curriculum, inclusion in general education classes for students with disabilities has become the accepted practice. Many students with specific learning disabilities experience difficulties with the general education curriculum because their reading ability falls significantly below the school curriculum and textbook instructional levels (Deshler & Schumaker, 1993). The Word Identification Strategy (Lenz, Schumaker, Deshler, & …

Diversity Leader: Case Study Of A Selected Organization's Transformation, Aileen Guerrero Zaballero

UNLV Theses, Dissertations, Professional Papers, and Capstones

Diversity initiatives have evolved from a focus on compliance-oriented training to a systematic approach which integrates the many dimensions of diversity in all aspects of business to enhance performance through the practice of organization development (OD) (Bendick, Egan, & Lofhjelm, 2001). Many organizations have implemented short term solutions to address the demographic changes in the workforce, but have had minimal results. When diversity interventions are conceptually grounded in organization development practices the results are much more substantial for both the employees and the organization (2001). The purpose of this qualitative case study was to explore the perceived influential factors of …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to examine the predictive validity of Risk Management Systems (RMS) as a risk assessment instrument. To date, a published validation study does not exist for the RMS. The study employs secondary data analysis to examine the predictive validity of RMS recidivism and violence scores on three outcomes: arrest, unsuccessful termination from supervision, and technical violations. The study sample consisted of 830 probationers from the United States Probation Office, District of Nevada. The analyses showed that RMS recidivism and violence scores were moderately predictive of all three outcomes.

Eminent Domain: The Unintended Consequences Of Kelo, Tracy Lynn Bower

UNLV Theses, Dissertations, Professional Papers, and Capstones

In recent years, local governments in the United States have increasingly used eminent domain to promote economic development, raising concerns among property-right advocates over what those advocates view as unlawful, or what should be unlawful, takings of private property in order to benefit another private property owner. This philosophical and legal dispute reached a crisis point in the 2005 United States Supreme Court decision in Kelo v. City of New London. In that decision, the court narrowly upheld a Connecticut Supreme Court ruling granting the City of New London permission to redevelop land that had been seized from existing homeowners …

Protection Of Macrophages J774a.1 By Purine Nucleoside Analogues From Bacillus Anthracis Mediated Necrosis, Zadkiel R. Alvarez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Eight years after the lamentable anthrax attacks, major scientific effort continues to be done, in order to stop imminent acts of bioterrorism. Innovative ways of therapy against the anthrax disease are being investigated. B. anthracis, the etiological agent of the infection, has a dormant stage in its life cycle known as the endospore. When conditions become favorable spores germinate, transforming into vegetative bacteria. In inhalational anthrax, the most fatal manifestation of the disease, spores enter the organism through the respiratory track, and are phagocytosized by alveolar macrophages of the lungs. Spores are able to sense nutrient availability, activating their germination …

Predisposition Factors Of Career And Technical Education Transfer Students: A Hermeneutic Phenomenology Study, Warren Glen Hioki

UNLV Theses, Dissertations, Professional Papers, and Capstones

Various econometric, sociological, and combined research models (e.g., Hossler and Gallagher's preeminent Three-Phase Model on College Choice) provide help in understanding high school students in their decision-making stages and college experience. Many studies that utilize these models on college choice strongly substantiate and perpetuate the long-standing dichotomy between students who aspire to attend college in pursuit of upward mobility through the traditional baccalaureate pathway versus a community college Career and Technical Education (CTE) pathway. High school students' aspirations to attend a 4-year institution, and more recently, the community college, are a focal point.

A review of the literature as it …

Quantity-Based Cost Forecasting System For Street Construction Projects, Nipesh Pradhananga

UNLV Theses, Dissertations, Professional Papers, and Capstones

Construction projects typically are not withdrawn after going into the competitive bidding process. The decision of contracting authorities regarding which projects will proceed to the bidding stage depends, in part, upon the early estimates of probable cost. Efforts are made to make this estimate as realistic as possible. Irrespective of the estimate of probable cost, the actual project cost is established by the amount of the winning bid.

This study analyzed historical bid data of street construction projects undertaken by the Public Works Department, Clark County, Nevada, from 1991 through 2006. The focus of this study was on utilizing statistical …

Systematic Analysis Of Identifying Key Dimensions Of Environmentally And Socially Responsible Hotels, Courtney Suess

UNLV Theses, Dissertations, Professional Papers, and Capstones

Development in Southeast Asia involves making good decisions for the future, so the idea that good planning can ignore sustainability is something of an oxymoron. Good development has to be sustainable and we have reached a point where the old ways of tourism development are intolerable. For example, hotels spring up without planning for the future. This short sightedness means natural endowments, like coastlines, erode and forests are cut down, chasing away the wildlife; or cultural history in the form of temples, historic buildings, and sacred places are destroyed. Ironically, tourism development is eradicating the very forms of product that …
