Comparison Of Hip And Knee Strength And Neuromuscular Activity In Subjects With And Without Patellofemoral Pain Syndrome, Lori Ann Bolgla, Terry R. Malone, Brian R. Umberger, Timothy L. Uhl

Physical Therapy Faculty Publications

Purpose/Background: Historically, patellofemoral pain syndrome (PFPS) has been viewed exclusively as a knee problem. Recent findings have suggested an association between hip muscle weakness and PFPS. Altered neuromuscular activity about the hip also may contribute to PFPS; however, more limited data exist regarding this aspect. Most prior investigations also have not concurrently examined hip and knee strength and neuromuscular activity in this patient population. Additional knowledge regarding the interaction between hip and knee muscle function may enhance the current understanding of PFPS. The purpose of this study was to compare hip and knee strength and electromyographic (EMG) …

The Relation Between Black Hole Mass And Host Spheroid Stellar Mass Out To Z~2, Vardha N. Bennert, Matthew A. Auger, Tommaso Treu, Jong-Hak Woo, Matthew A. Malkan

Physics

We combine Hubble Space Telescope images from the Great Observatories Origins Deep Survey with archival Very Large Telescope and Keck spectra of a sample of 11 X-ray-selected broad-line active galactic nuclei in the redshift range 1 < z < 2 to study the black-hole-mass-stellar-mass relation out to a look-back time of 10 Gyr. Stellar masses of the spheroidal component (M _sph, ) are derived from multi-filter surface photometry. Black hole masses (M _BH) are estimated from the width of the broad Mg II emission line and the 3000 Å nuclear luminosity. Comparing with a uniformly measured local sample and taking into account selection effects, we find evolution in the form M _BH/M _sph, (1 + z)^{1.96 …}

The Effect Of Safety Climate, Teamwork, And Sustainable Motivation On Nurse Job Satisfaction And Intent To Stay, M'Lynda Owens

Nursing Theses and Dissertations

Nursing is a hazardous occupation, and occupational safety in healthcare, particularly hospitals, is gaining attention. The Institute of Medicine (2003) ranked hospitals in the top five industries for occupational injuries and illness. This study explored the relationship between sustained motivation in nurses as depicted by their perceptions of workplace safety climate, teamwork climate, and autonomy and their job satisfaction and intent to stay at their current jobs. Sustained motivation was manifested as the ability of the nurses to consistently and persistently attend to routine activities such as actions to ensure safety. Over one-third (36%) of the variance in sustained motivation …

The Influence Of Ethnic Identity And Family Support On Posttraumatic Symptoms In Maltreated Youth, Harpreet Kaur

UNLV Theses, Dissertations, Professional Papers, and Capstones

Maltreated children are at greater risk of developing PTSD than nonmaltreated children (Ackerman et al., 1998; Epstein et al., 1997; Famularo et al., 1996; Kilpatrick et al., 2003; Widom, 1999). This study sought to assess the role of ethnicity, ethnic identity, and family support on the effects of maltreatment and trauma in adolescents. Participants (n=145) included adolescents from Child Haven, a Department of Family Services (DFS)-related site in Las Vegas, and youths in foster care assessed at the offices of Dr. Stephanie Holland. The first hypothesis was that non-Caucasian youth would have higher levels of PTSD-related symptoms than Caucasian youth. …

Energy-Based Analysis Of Utility Scale Hybrid Power Systems, Kwame Agyenim-Boateng

UNLV Theses, Dissertations, Professional Papers, and Capstones

The promise of large-scale use of renewables such as wind and solar for supplying electrical power is tempered by the sources' transient behavior and the impact this would have on the operation of the grid. Among the methods cited for addressing some of those concerns are exploring the complementary nature of solar and wind power generation, and through the use of supplemental energy storage. While the technology for the latter has not been proven to be economical on a large scale at the present time, some assessments of what magnitude is required can be made. An energy-based analysis of utility …

Environmental Impact Of The Three Kids Mine Tailings, Henderson, Nv, Ji Hye Park

UNLV Theses, Dissertations, Professional Papers, and Capstones

This research focused on the distribution of the Three Kids Mine tailings in surface soils in and around the mine in Henderson, Nevada. It is situated next to the communities of Calico Ridge and Lake Las Vegas Resort, and, just the west of the Lake Mead Recreation area. Even though the mine has been inactive for almost 50 years (1917-1961), tailing piles and other sources of contamination on the mine are currently exposed to the atmosphere. In this study, surface soil samples were collected along eight transects emanating from the center of Three Kids Mine tailing piles up to five …

For The Benefit Of Others: Harriet Martineau: Feminist, Abolitionist And Travel Writer, Laura J. Labovitz

UNLV Theses, Dissertations, Professional Papers, and Capstones

One of the distinctive and remarkable traits of Harriet Martineau was her need to publish information that she believed would benefit society. Her publications - Illustrations of Political Economy (1832), Society in America (1837) and Retrospect of Western Travel (1838) - have the distinct characteristic of being published with the intent to inform and educate the British public. Scholars have focused on her later 1848 publication, Eastern Life: Present and Past, as her most important publication. Yet I will argue that it was her earlier works which set the stage for this later, better known book. Her travel to the …

Spectroscopic Studies Of Melamine At High Pressure, Martin Donald Galley

UNLV Theses, Dissertations, Professional Papers, and Capstones

We have performed mid- and far- Infra Red (IR) absorption, Raman spectroscopy, and angular dispersive x-ray diffraction (XRD) studies on melamine under high pressure and room temperature. We have verified the presence of two prior reported phase transitions, the first between 1-2 GPa, and the second between 7-9 GPa. We have also found evidence of a third unreported phase transition between 14-16 GPa, during which, there was a sudden disappearance of all low energy peaks (^-1 ) in both the Raman and IR spectra. The far-IR peak movement experiences a discontinuity as the rate of peak movement suddenly changes. …

Identifying Effort Estimation Factors For Corrective Maintenance In Object-Oriented Systems, Michael J. Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

This research identifies factors that impact software maintenance effort by exploring the decision-making process of expert estimators of corrective maintenance projects by using qualitative methods to identify the factors that they use in deriving estimates. We implement a technique called causal mapping, which allows us to identify the cognitive links between the information that estimators use, and the estimates that they produce based on that information. Results suggest that a total of 17 factors may be relevant for corrective maintenance effort estimation, covering constructs related to developers, code, defects, and environment. When these factors are rank-ordered, they demonstrate that some …

Direct Contact Pyrolysis Of Hydrocarbons: A Source Of Hydrogen And Interesting Carbon Formations, Peter G. Faught

UNLV Theses, Dissertations, Professional Papers, and Capstones

The work detailed in this document looks at a novel liquid metal supported catalytic system for the generation of hydrogen by decomposition of ethanol through direct contact pyrolysis. The hydrogen is produced at relatively low temperatures (500-600°C) and has carbon and water as co-products. It should be noted that CO is not observed as a product at these low temperatures. This is to be contrasted with the hydrogen produced at higher temperature from ethanol which does contain carbon monoxide. The presence of carbon monoxide in hydrogen complicates fuel cell operation and catalytic chemical processes. Thus, the lack of CO in …

Processj: A Process-Oriented Programming Language, Matthew Sowders

UNLV Theses, Dissertations, Professional Papers, and Capstones

Java is a general purpose object-oriented programming language that has been widely adopted. Because of its high adoption rate and its lineage as a C-style language, its syntax is familiar to many programmers. The downside is that Java is not natively concurrent. Volumes have been written about concurrent programming in Java; however, concurrent programming is difficult to reason about within an object-oriented paradigm and so is difficult to get right.

occam -π is a general purpose process-oriented programming language. Concurrency is part of the theoretical underpinnings of the language. Concurrency is simple to reason about within an occam -π application …

Quantification Of Stochastic Uncertainty Propagation For Monte Carlo Depletion Methods In Reactor Analysis, Quentin Thomas Newell

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Monte Carlo method provides powerful geometric modeling capabilities for large problem domains in 3-D; therefore, the Monte Carlo method is becoming popular for 3-D fuel depletion analyses to compute quantities of interest in spent nuclear fuel including isotopic compositions. The Monte Carlo approach has not been fully embraced due to unresolved issues concerning the effect of Monte Carlo uncertainties on the predicted results.

Use of the Monte Carlo method to solve the neutron transport equation introduces stochastic uncertainty in the computed fluxes. These fluxes are used to collapse cross sections, estimate power distributions, and deplete the fuel within depletion …

The following study will present an examination of factors that impact levels of voting activity among American citizens from 1972 through 2004. The subject of voter turnout has been thoroughly examined by political scientists over the years, as have aspects of youth voting and the influence of education. Many of the same variables presented by scholars in recent years will be employed in this study. However, these earlier studies tend to look only at individual level variables in explaining voter turnout. This study will contribute to a more complete understanding of voting through the analysis of individual, regional, and temporal …

Global And Specific Controls Of Protein Synthesis In Hibernators, Peipei Pan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Mammalian hibernation is a highly dynamic physiological process that is composed of a series of torpor bouts, wherein hibernators oscillate between periods of torpor and interbout arousal. Although normally vital to homeostasis, many energetically consumptive processes such as translation or protein synthesis are virtually ceased during hibernation. Earlier studies indicated that protein synthesis had fallen to almost negligible levels. Cap-dependent initiation of translation is well regulated by eukaryotic translation initiation factor 4E (eIF4E) and its binding partner eIF4E-binding protein 1 (4E-BP1) when hibernators cycle in and out the torpor state. Herein, I investigated well-characterized regulatory mechanisms of global and specific …

Development Of A Simulation Tool For Analysis Of Freeway Crashes Due To Cell Phone Usage, Sourabh Sriom

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research shows that drivers are susceptible to numerous distractions while driving which can be held responsible as the reason of a crash. Usage of cell phones, i.e. talking or texting while driving is considered one of the prominent distractions which causes a crash. This dissertation aims to study the number of crashes occurring on the freeways and their relation with the drivers of these cars using cell phones while they are driving. Since crashes occur relatively less frequently, the study of crashes is done using what is called the "rare event" theory. Java based simulations are done to model a …

Korean Mask-Dance And Aristotle's Poetics, Teayong Pakr

UNLV Theses, Dissertations, Professional Papers, and Capstones

Korean mask-dance is the traditional theatre of Korea. It was formerly the country's most well-known form of drama among traditional theatrical entertainments. This study explores the theatrical structure of Korean mask-dance as well as its historical background.

The rise of Korean mask-dance may be traced back to the shamanistic village ritual which gradually became similar to the extant form after absorbing aspects of the Buddhism festival through the Goryeo Dynasty, which lasted from 918-1392). During the Joseon Dynasty (1392-1910), the mask-dance had acquired its basic form with aspects of professional theatrical entertainment. The mask-dances have been performed during traditional holidays …

Fall Prevention Training And Its Impact To Southern Nevada Construction Workers, Vedaspati Joshi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Death and injury from falls are a long-standing and continuing problem in construction, responsible for at least a third of the construction deaths in the U.S. from 2004 to 2007. Each of those years, Nevada has exceeded the national percentage. Although 29 CFR 1926.503 sets forth Occupational Safety and Health Administration (OSHA)'s requirements that construction employers train employees exposed to fall hazards and document such training, the incidence of deaths and injuries from falls are an indicator that this training was not provided or else was not effective.

Conventional fall protection training is more narrowly focused on recognizing fall hazards …

The American Homophilic School Of Composition, Rik Noyce

UNLV Theses, Dissertations, Professional Papers, and Capstones

A small enclave of gay composers in New York, led by Aaron Copland (1900-1990) and Virgil Thomson (1896-1989), established a distinct twentieth-century musical sound that became synonymous with America. Copland and Thomson were prominent among a group of gifted gay musicians and conductors in New York in the 1930s, 40s and 50s. While perhaps not self-identifying as gay, as the term had not yet been coined, they did however acknowledge, honor, and support one another's lives as being homosexual. Is it possible that something as seemingly unrelated as sexual preference could, in fact, impact a musical style?

In this document, …
