The dearth of black men in our classrooms can be reduced by collecting data as to the reasons that influence their decisions about the education field.

This qualitative study examined the experiences and perspectives of African American men serving as classroom teachers to identify common factors that may influence African Americans, in general, to …

Response To Intervention Data In Grade Retention Decisions: How Is It Used?, Cheryl Anne Mayfield

UNLV Theses, Dissertations, Professional Papers, and Capstones

For over 100 years, retention has been an intervention used with students who are not performing at expected levels. Despite the lack of evidence that retention is an effective means of improving academic outcomes, retention continues to be used today. Response to Intervention (RTI) is a strategy to provide support to struggling students in an effort to increase their academic performance, with the caveat that students who do not respond to interventions are candidates for special education evaluation. With RTI, data are generated. The impetus for the creation of the RTI model was its use for identifying students who may …

A Study Of District Leadership Practices In The Principal Professional Learning Community, Danielle Grace Miller

UNLV Theses, Dissertations, Professional Papers, and Capstones

This qualitative study was implemented in an urban, Title I school district in the southern portion of the United States.

A Forensic Identification Utility To Create Facial Approximations Using Cone-Beam Computed Tomography Of 100 Hispanic Females: A Pilot Study, Behzad Nejat

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction:Estimation of facial soft tissue appearance from human skeletal remains is often necessary in forensic identification. This process has been referred to as facial reconstruction or facial approximation and is a branch of forensic facial anthropology. Original methods for facial approximation originated in nineteenth century Europe and consisted of artists shaping clay over skull models using average soft tissue depths measured in cadavers. The last two decades have introduced numerous computerized techniques that have digitized this process while attempting to accurately and objectively define the relationship between a skull and its overlying soft tissue. This pilot study describes a method …

The Impact Of Advanced Wastewater Treatment Technologies And Wastewater Strength On The Energy Consumption Of Large Wastewater Treatment Plants, Timothy Stephen Newell

UNLV Theses, Dissertations, Professional Papers, and Capstones

Wastewater treatment is an energy intensive process often requiring the use of advanced treatment technologies. Stricter effluent standards have resulted in an increase in the number of wastewater treatment plants (WWTPs) with advanced treatment over time. Accordingly, associated energy consumption has also increased. Concerns about lowering operating costs for WWTPs and reducing associated greenhouse gas generation present an incentive to investigate energy use in WWTPs. This research investigated the impact of wastewater strength and the introduction of advanced treatment technologies, to replace traditional technologies on energy use to treat wastewater in WWTPs. Major unit processes were designed for a 100 …

Safety First -In Search Of Justice -School & Law Enforcement Agency Partnerships, Michael Anthony Pickett

UNLV Theses, Dissertations, Professional Papers, and Capstones

ABSTRACT

Educational problems are many and varied. At-risk students, achievement gaps and poor student outcomes are hot topics that beg for improvement in equity across the board and stand in the way of achieving excellence. These educative, albeit, social justice issues are not new, but rather, are old problems revisited (Kaestle, 1983; Morrison, 2003). Additionally, the issue of violence in schools is also recognized as not only a social justice problem but also a public health problem (Mercy & O'Carroll, 1988) and is perhaps the most pressing societal issue related to children and youth today. "Safe schools are the concern …

The Abundance And Distribution Pattern Of Quagga Mussels In The Las Vegas Bay Of Lake Mead, Nevada And Potential Correlation With Environmental Parameters, Scott Rainville

UNLV Theses, Dissertations, Professional Papers, and Capstones

The non-native quagga mussel [Dreissena bugensis (Andrusov, 1897)] was initially discovered in Boulder Basin of Lake Mead, Nevada-Arizona on January 6, 2007. This occurrence marked the first biological invasion of dreissenid mussels in the Western U.S., following a significant North American range expansion of invasive quagga mussels from populations that invaded and colonized the Great Lakes Region in the Northeastern U.S. during 1991. This nonindigenous mollusk species quickly spread from Boulder Basin and became established throughout the entire reservoir by the end of 2007, with the exception of the inner Las Vegas Bay. There was an apparent absence of settled …

A Critical Edition Of Gustave Vogt's 4eme Solo De Concert, Mark Runkles

UNLV Theses, Dissertations, Professional Papers, and Capstones

As oboe professeur titulaire at the Paris Conservatory from 1816-53, Gustave Vogt established his importance as a pedagogue by teaching many leading nineteenth century European oboists, and his influence can be traced to numerous living oboists. Additionally, Vogt played a seminal role in developing a virtuosic Romantic oboe style that paralleled the virtuosic styles developed for the more prevalent Romantic solo instruments, the piano and violin. His music is rarely played today, and Vogt remains a largely unknown figure even within the oboe community. The purpose of this study is to develop a critical edition of Gustave Vogt's 4ème Solo …

The Non-Gaming Business Of The Gaming Industry: Evaluating The Contribution Of Non-Gaming Amenities At A Casino-Resort Property, Elena Shampaner-Ghiassi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Previous studies on this topic show that all non-gaming amenities at a casino-resort property generate revenue in two ways. First, an amenity directly contributes to companies' overall profits when consumers spend on a particular amenity more than it costs the company to provide that amenity (Roehl, 2006). Second, these amenities can make an indirect contribution defined as the profit impact of an amenity on another profit center at the property (Dandurand & Ralenkotter, 1985); however, this contribution does not show directly on the amenity's financial statements (Roehl, 1996).

The purpose of this paper is to estimate the indirect gaming (both …

Credentialing Success In Respiratory Therapy Education: Revisiting Bourdieu's Concepts Of Field And Capital, Karen Lightbody Shaw

UNLV Theses, Dissertations, Professional Papers, and Capstones

The field of Respiratory Therapy (RT) is expected to experience a workforce shortfall over the next decade. The numbers of both program applicants and graduates have declined in recent years, necessitating strategies to improve board exam pass rates for future graduates. In response to the pending employment crisis, the Commission on Accreditation for Respiratory Care has published Programmatic Outcomes Data detailing individual program statistics. A theoretical framework adapted from Pierre Bourdieu's Concepts of Field and Capital was proposed to explain a possible re-stratification of RT programs. It states, in part, that a modification of position-takings within the RT educational field …

Csa Survivors: What Heals And What Hurts In A Couple Relationship, Laura S. Smedley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Childhood sexual abuse (CSA) is a significant trauma that affects a person's self-concept and the ability to form healthy intimate relationships later in adulthood. Approximately 20% of adults who experience childhood sexual abuse go on to evidence serious psychopathology in adulthood (Harway & Faulk, 2005). Besides individual disturbances, CSA survivors struggle with many relational difficulties. These difficulties are usually most pronounced among their intimate partners (Reid, et al., 1995). According to attachment theory, attachment injuries are best healed in the context of a healthy, intimate relationship (Kochka & Carolan, 2002) (MacIntosh & Johnson, 2008). Conversely, the couple relationship may be …

Topics In Galaxy Formation: Pairwise Velocities Of Dark Matter Halos And Molecular Hydrogen Regulated Star Formation In Cosmological Simulations, Robert Jo Thompson

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this dissertation we investigate two distinct challenges within the concordance LCDM model and an unrelated project.

The first is a discrepancy between theory and observation. A massive galaxy sub-cluster known as the `bullet' has fallen through a more massive parent galaxy cluster at a redshift of z=0.296.

Theory finds that in order to reproduce the observational quantities of this cluster, an unusually high relative velocity of v12=3000 km/s between the two cluster's parent halos is required.

We quantify the statistical probability of producing a `bullet-like' halo pair within large N-body simulations, and

conclude that either the LCDM model is …

Theory Versus Practice: A Study Of Strategy Making In Five Public Mba Programs, Michael Alwyn Wilde

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study examined whether coercive, normative and mimetic isomorphic mechanisms contribute to the strategies public MBA programs develop and implement in their quests to differentiate themselves. An additional purpose was to examine whether influential environmental elements impact strategy development in ways that make these organizations more similar than different.

In depth interviews were conducted in an attempt to discover the experiences and perspectives of five current directors of MBA programs in public institutions of higher education. Purposeful sampling, in the form of convenience sampling within a clearly defined population, was used.

The findings suggest that none of the five MBA …

The Uses And Gratifications Of Dance Reality Television Shows, Heather M. Yuille

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Uses and Gratifications of Dance Reality Shows

Competition based dance reality shows are a sub-category under the reality television show genre. One way to add to the growing body of research about reality television shows is to study each sub-category individually in terms of uses and gratifications theory. Therefore this research looked into the reasons why people watch dance reality shows. Since dance is an art form that has deep historic roots, has experienced highs and lows in terms of public perception and has experienced a strong resurgence recently within the realm of reality television, it proves to be …

Being Active And Impulsive: The Role Of Goals For Action And Inaction In Self-Control, Justin Hepler, Dolores Albarracin, Kathleen C. Mcculloch, Kenji Noguchi

Faculty Publications

Although self-control often requires behavioral inaction (i.e., not eating a piece of cake), the process of inhibiting impulsive behavior is commonly characterized as cognitively active (i.e., actively exerting self-control). Two experiments examined whether motivation for action or inaction facilitates self-control behavior in the presence of tempting stimuli. Experiment 1 used a delay discounting task to assess the ability to delay gratification with respect to money. Experiment 2 used a Go/No-Go task to assess the ability to inhibit a dominant but incorrect motor response to the words "condom" and "sex". The results demonstrate that goals for inaction promote self-control, whereas goals …
