Effects Of Oxygen Variation On The Ecology Of Devil's Hole, Death Valley National Park, Norma J. Azad

UNLV Theses, Dissertations, Professional Papers, and Capstones

The inability to rear Devil's Hole pupfish, Cyprinodon diabolis Wales, in captivity, when captive propagation has been successful with other species of pupfish, led to the examination of environmental factors which are unique to Devil's Hole. It has been suggested that C. diabolis regularly experience developmental arrest due to hypoxic conditions. This arrest may be reversible in areas of the shallow shelf during periods of photosynthetic activity. Oxygen measurements over the shallow shelf reveal a gradient of oxygen variation with the greatest diel variability over the inner portion of the shelf diminishing to nearly imperceptible diel variation toward the outer …

Neutral Dissociation Of Hydrogen Following Photoexcitation Of Hcl At The Chlorine K Edge, D. L. Hansen, J. Cotter, G. R. Fisher, K. T. Leung, R. Martin, Paul Neill, Rupert C. Perera, I. A. Sellin, Marc Simon, Y. Uehara, B. Vanderford, S. B. Whitfield

Chemistry and Biochemistry Faculty Research

Time-of-flight mass spectroscopy was used to study the relaxation dynamics of HCl following photoexcitation in the vicinity of the Cl K edge (~2.8 keV) using monochromatic synchrotron radiation. At the lowest resonant excitation to the 6ơ* antibonding orbital, almost half of the excited molecules decay by emission of a neutral H atom, mostly in coincidence with a highly charged Cln1 ion. The present work demonstrates that neutral-atom emission can be a significant decay channel for excited states with very short lifetimes (1 fs). [S1050-2947(98)03604-X]

Crime Prevention Through Environmental Design: An Analysis Of The Boulevard Mall, Kenneth Mac Leod

UNLV Theses, Dissertations, Professional Papers, and Capstones

Many case studies have been published that report a decrease in crime as a result of Crime Prevention Through Environmental Design (CPTED). Although methodologies and results of some studies have been questioned, there is agreement that the designed environment can influence human behavior.

Data in this study were accumulated by the investigation of a local mall. Mall management and head of security reported a decrease in all types of crime after improving and adding security measures for customers and store employees. My hypothesis was the mall provided a high number of CPTED features which would result in a low number …

Bowen Ratio Estimates Of Evapotranspiration For Stands On The Virgin River In Southern Nevada, Dale A. Devitt, A. Sala, S. D. Smith, J. Cleverly, L. K. Shaulis, R. Hammett

Life Sciences Faculty Research

A Bowen ratio energy balance was conducted over a Tamarix ramosissima (saltcedar) stand growing in a riparian corridor along the Virgin River in southern Nevada. Measurements in two separate years were compared and contrasted on the basis of changes in growing conditions. In 1994, a drought year, record high temperatures, dry winds, and a falling water table caused partial wilt of outer smaller twigs in the canopy of many trees in the stand around the Bowen tower. Subsequently, evapotranspiration (ET) estimates declined dramatically over a 60‐day period (11 mm d−1 tod−1). In 1995, the Virgin River at the Bowen tower …

Four Commentaries: How We Can Better Protect Children From Abuse And Neglect, Leroy H. Pelton

Social Work Faculty Research

The fundamental structure of the public child welfare system is that of a coercive apparatus wrapped in a helping orientation. Agencies ostensibly having the mission to help are mandated to ask whether parents can be blamed for their child welfare problems, and these agencies have the power to remove children from their homes. Thus, the public child welfare agency has a dual-role structure: On one hand, the agency attempts to engage in prevention and support, and to promote family preservation; on the other hand, it also has the task of investigating complaints against parents and removing children from them. This …

College of Education Multicultural & Diversity Newsletter

As educators and future educators, we will be working with students from diverse groups and all walks of life. Many of us enter this field entrenched in our own culture with no real understanding of how others' life experiences have influenced their values and beliefs. The multicultural courses in the College of Education force us to examine how we came to adopt our values and from where our beliefs originated. No other course in the graduate curriculum forces us to challenge the myths and stereotypes of American society as profoundly as these courses.

A Study Of Transconductance Degradation In Hemt Using A Self-Consistent Boltzmann-Poisson-Schrodinger Solver, Rahim Khoie

Electrical & Computer Engineering Faculty Research

A self-consistent Boltzmann-Poisson-Schrödinger Solver is used to study the transconductance degradation in high electron mobility transistor (HEMT), which has extensively been reported by both experimental [1]-[8] and computational [9]-[ 13] researchers. As the gate voltage of a HEMT device is increased, its transconductance increases until it reaches a peak value, beyond which, the transconductance is degraded rather sharply with further increase in applied gate bias. We previously reported a two-subband self-consistent Boltzmann-Poisson- Schrödinger Solver for HEMT. [14] We further incorporated an additional self-consistency by calculating field-dependent, energy-dependent intersubband and intrasubband scattering rates due to ionized impurities and polar optical phonons.[15] …

Five developmental phases were employed to identify, develop, and field-test a questionnaire and a training module with teachers enrolled in university coursework; A quasi-experimental design was utilized including an experimental and a control group. Subjects in the experimental group received training in using the Universal Format and translated research articles. Subjects in the control group translated research articles, but received no …

An Analysis Of The Causes And Consequences Of Urban Sprawl On The Las Vegas Valley, Robert R Schmidt

UNLV Retrospective Theses & Dissertations

Sprawl, as an urban form, has been vociferously attacked by some social scientists as an inefficient and ineffective form urban form which contributes (if not directly causes) to a variety of social ills, it has been embraced by other social scientists as a positive force in today's urban form. This paper examines the two major theoretical approaches to the causes and consequences of sprawl by conducting a case study of the impact of sprawl on the Las Vegas community. validity of the major arguments for and against sprawl will be evaluated in the context of the empirical evidence available today. …

Molecular Analysis Of Microbial Diversity Within Yucca Mountain, Yingchun Wu

UNLV Retrospective Theses & Dissertations

Yucca Mountain is the proposed site for a high-level nuclear waste repository. As part of the site characterization project, an estimation of microbial diversity was conducted. In this study, the 16S ribosomal DNA sequences of culturable isolates were determined and used for tentatively identification of bacterial strains. The results of identification by 16S rDNA sequence data were also compared to MIDI analysis, an independent phenotypic approach for bacterial identification; It is accepted that culturable strains only represent a small portion of microbial community in the environment. In order to eliminate bias associated with cultivation, total DNA was extracted from rock …

A Study Of The Participation Of Marginally Academic Students In Extracurricular Activities And The Relation To School Persistence, Annette Jean Conners-Harris

UNLV Retrospective Theses & Dissertations

The purpose of this study was to explore whether participation in extracurricular activities kept marginally academic students in school. This study differed from most dropout studies and extracurricular activities studies in that it focused on the idea that there may be a connection between these two issues and highlighted participation in activities as being critical to students remaining in school. Sub problems such as the number of activities participated in, the average number of hours per week devoted to participation, the type of membership status (leader or member), and the social character of the activity (team effort or an individual …

Critical Incidents In The Gaming Industry: Perceptions Of Guests And Employees, Lesley Jeanne Johnson

UNLV Retrospective Theses & Dissertations

During the service encounter or "moment of truth" the customer judges the quality of the service organization. Not all guest-employee service encounters, however, are equally important. For every organization there are probably particular. service encounters that are critical to customer satisfaction. Before they can initiate efforts to service their customers, service firms must first identify and manage critical service encounters. Using the environment of the gaming industry, this exploratory research investigated the concept of identifying and evaluating critical service encounters from the perspectives of both guests and customer-contact employees and measured the level of congruence/incongruence between the two parties involved …

Motives And Characteristics Of Gift-Giving At The University Of Nevada, Las Vegas, Judy M Belanger

UNLV Retrospective Theses & Dissertations

Public institutions of higher learning need to increase reliance on private financial support for a portion of their revenue stream due to decreases in public financial support and increases in institutional needs. To help meet university demands for private funding, fundraising bodies, such as university foundations, need to target their limited resources in directions that will yield the greatest financial results. One way to do this is to identify individuals who are more likely to provide monetary gifts to the university and target fundraising efforts toward them; The purpose of this study was to build a predictive model that was …
