"Surely, A Wench Can Choose Her Own Work!" Women Coal Miners In Paonia, Colorado, 1976-1987, Dona G Gearhart Jan 1995

"Surely, A Wench Can Choose Her Own Work!" Women Coal Miners In Paonia, Colorado, 1976-1987, Dona G Gearhart

UNLV Retrospective Theses & Dissertations

In 1842 the British Parliament passed the Mines and Collieries Act which excluded women from working in underground mines. The legislation created a gender based, industry-wide segmentation of labor that persisted in Great Britain and the United States for 130 years. Post-World War II social and legal changes created a context from which women reappropriated their choice to seek jobs as underground coal miners. Women's representation in the industry increased into the 1980s, peaking at between eight and eleven percent of the workforce, but by 1983 their numbers began to substantially deCline After the coal boom of the 1970s ended, …

A Framework For Modeling Risk And Emergency Response In Hazardous Materials Transportation, Emelinda Maano Parentela Jan 1995

A Framework For Modeling Risk And Emergency Response In Hazardous Materials Transportation, Emelinda Maano Parentela

UNLV Retrospective Theses & Dissertations

Hazardous materials transport is a significant economic activity. Routing is one of the key issues in hazardous materials transport. Cost and risk are primary factors influencing routing. Emergency preparedness is an issue that is common to all of these. Traditionally, risks and emergency preparedness have been addressed as two interdependent issues, but the interactions between them have not been addressed explicitly. This often results in risk estimates that ignore the effect of emergency preparedness; This research presents a framework for quantifying effects of emergency preparedness on risk of hazardous materials transportation. Risk estimates are typically based on the probability of …

Analysis Of The Genus Larrea: Molecular Systematics And Polyploidy, Kimberly Lynn Hunter Jan 1995

Analysis Of The Genus Larrea: Molecular Systematics And Polyploidy, Kimberly Lynn Hunter

UNLV Retrospective Theses & Dissertations

The evolutionary and biogeographic history of the genus Larrea was assessed by determining patterns of genetic variation in chloroplast DNA, nuclear ribosomal internal transcribed spacer (ITS1) DNA, and temporal and spatial distributions of the three geographically distinct polyploids of Larrea tridentata. The phylogenetic relationships, based on the chloroplast DNA (cpDNA) restriction site analysis, were congruent with morphological studies. Cytoplasmic gene flow was postulated to account for identical haplotypes being shared between L. nitida and L. cuneifolia from South America, with L. nitida as the putative maternal donor. Two distinct cpDNA haplotypes were found in North American L. tridentata, and one …

The Use Of Temporal Constructs As A Model For Understanding Perceptions Of Environmental Hazard, Victoria Koehler-Jones Jan 1995

The Use Of Temporal Constructs As A Model For Understanding Perceptions Of Environmental Hazard, Victoria Koehler-Jones

UNLV Retrospective Theses & Dissertations

An extreme physical event, such as a flood, becomes a hazard when social structures and systems are endangered by it--and it becomes a disaster when these structures and systems are actually disrupted. As the twenty-first century approaches and population pressures continue to grow, natural disasters will occur with greater frequency, bringing serious consequences for more people than ever before. The problem of minimizing damage is aggravated by inadequate recognition of hazard in time to mitigate or prevent disaster; This thesis develops a framework for understanding how perceptions of natural hazard are associated with ideas about the passage of time and …

Differential Oppression, Alienation And Edgework: Keys To Understanding Juvenile Delinquency, William John Miller Jan 1995

Differential Oppression, Alienation And Edgework: Keys To Understanding Juvenile Delinquency, William John Miller

UNLV Retrospective Theses & Dissertations

This study tests several tenets of the theory of differential oppression. The theory of differential oppression suggests that the social order is created by adults for adults. Children are forced to conform to this order, despite their possible reluctance, because they lack the power to create meaningful social change. The extended use of power by adults leads to the oppression of children. The theory of differential oppression maintains that delinquency is one possible reaction to oppression; This study also attempts to expand the theory of differential oppression by addressing the role of alienation in the development of delinquency. It suggests …

Promoting The Nation: The Rise Of Ethno-Nationalism And Early Modern Drama, David Elwood Phillips

UNLV Retrospective Theses & Dissertations

Most political scientists locate the rise of ethno-nationalism in the late sixteenth and early seventeenth centuries. English ethno-nationalism is developed throughout that period through a xenophobic identification of racial, religious, and national others. This study examines how Thomas Kyd, Christopher Marlowe, Willian Shakespeare, Ben Jonson, and Thomas Middleton promote English ethno-nationalism through the use of stereotypes, especially the collection of stereotypes known as the Black Legend of Spain. Chapter one outlines the theory and psychology of ethno-nationalism, laying the foundation for subsequent chapters devoted to specific plays, including Kyd's The Spanish Tragedy, Marlowe's The Jew of the Malta, Shakespeare's The …

Travel Demand Modeling For Developing Countries, Satyakala Jarugumilli Jan 1995

Travel Demand Modeling For Developing Countries, Satyakala Jarugumilli

UNLV Retrospective Theses & Dissertations

The transportation planning process or travel demand forecasting process which is most commonly used at present, called the Urban Transportation Planning Process (UTPP), has its origins in studies performed about three decades ago in urban areas in the United States. This conventional planning process was designed primarily for the western/developed world where affordability and accessibility to a personal automobile is a common feature; The UTPP based models used in forecasting future travel demand rely heavily on socio-economic variables that are associated with an individual's propensity to travel. The socio-economic environments in the developing and the under-developed world are different from …

A Classification Of Groups Satisfying The Converse Of Lagrange's Theorem, Laura Earl Laurent Jan 1995

A Classification Of Groups Satisfying The Converse Of Lagrange's Theorem, Laura Earl Laurent

UNLV Retrospective Theses & Dissertations

This paper is a classification of finite groups satisfying the converse of Lagrange's Theorem. We begin by showing a series of inclusions of classes of finite groups: p-groups {dollar}\subseteq{dollar} nilpotent {dollar}\subseteq{dollar} supersolvable {dollar}\subseteq{dollar} polycyclic {dollar}\subseteq{dollar} solvable. The crucial point of the paper consists of the proof that the class of supersolvable groups is contained in the class of converse Lagrange groups while the class of polycyclic groups is not. We also show that finite cyclic groups and finite abelian groups are included in the class of converse Lagrange groups. Finally, we give an example to show that the class of …

A Gradient Analysis Of Coleogyne Communities In Southern Nevada, Simon Adams Lei Jan 1995

A Gradient Analysis Of Coleogyne Communities In Southern Nevada, Simon Adams Lei

UNLV Retrospective Theses & Dissertations

Species richness, density, and abundance in Coleogyne ramosissima (blackbrush) shrublands were compared on 15 elevational transects in the Spring and Sheep Mountain Ranges adjacent to the Las Vegas Valley. Coleogyne shrublands shared relatively broad upper and lower ecotones with Pinus-Juniperus and Larrea-Ambrosia vegetation, respectively. Lower Coleogyne ecotones generally had the highest species richness, and Pinus-Juniperus woodlands had the lowest species richness; Detrended correspondence analysis (DECORANA) suggested that elevation and soil depth were significantly associated with the distribution of stand and species groups identified from two-way indicator species analysis (TWINSPAN) in the Spring and Sheep Mountain Ranges. Precipitation and soil moisture …

High Frequency Surface Estimation, Sai Prasad V Pallati Jan 1995

High Frequency Surface Estimation, Sai Prasad V Pallati

UNLV Retrospective Theses & Dissertations

Mountain generation can be considered a part of the general theory of surface estimation; In this thesis, two methods have been presented to generate fractals--fast Fourier method and a new generalized stochastic subdivision method. Also, a new surface estimation method has been introduced that deals with points of unequal powers. The uniqueness of this method is the usage of splines to calculate the arc lengths between the points, as opposed to Euclidean distances used in Kriging. The fast Fourier technique has been used to generate mountains in particular; also, some extensions have been suggested, whereby different sets of mountains can …

New Methods In Image Compression Using Multi-Level Transforms And Adaptive Statistical Encoding, Thomas William Pike Jan 1995

New Methods In Image Compression Using Multi-Level Transforms And Adaptive Statistical Encoding, Thomas William Pike

UNLV Retrospective Theses & Dissertations

The need to meet the demand for high quality digital images, with comparatively modest storage requirements, is driving the development of new image compression techniques. This demand has spurred new techniques based on time to frequency spatial transformation methods. At the core of these methods are a family of transformations built on basis sets called "wavelets." The wavelet transform permits an image to be represented in a substantially reduced space by transferring the energy of the image to a smaller set of coefficients. Although these techniques are lossy as the compression ratio rises, very adequate reconstructions can be made from …
