From Sin To Sickness: A Sociological History Of The Problem Gambler, Bo Jason Bernhard Jan 2002

From Sin To Sickness: A Sociological History Of The Problem Gambler, Bo Jason Bernhard

UNLV Retrospective Theses & Dissertations

Long before medical and psychological experts determined that problem gambling qualified as a mental illness, moral experts determined that this problem could be "diagnosed" as a sin. This research examines pre-1915 gambling literature to determine the ways in which people who gambled too much were identified, named, and "treated" socially. Interestingly, virtually all of our current diagnostic criteria were identified by moral thinkers hundreds of years ago. Implications for the sociological history of problem gambling, the sociology of mental illness, and the sociology of religion and morality are discussed.

Tadpole Shrimp (Triops Longicaudatus) Responses To Acute And Developmental Hypoxic Exposure, Stacey Lynn Harper Jan 2002

Tadpole Shrimp (Triops Longicaudatus) Responses To Acute And Developmental Hypoxic Exposure, Stacey Lynn Harper

UNLV Retrospective Theses & Dissertations

Tadpole shrimp Triops longicaudatus (Crustacea: Branchiopoda: Notostraca) were reared under normoxic (19--21 kPa O2), moderate (10--13 kPa O2) or severe (1--3 kPa O2) hypoxic conditions to investigate the effects of developmental Po2 (partial pressure of oxygen) on adult metabolic, respiratory and cardiovascular physiology. Growth rates were independent of developmental Po2, although adult body size was significantly smaller in tadpole shrimp reared under severe hypoxic conditions relative to those reared under normoxic conditions. Most organisms increase respiratory surface area in response to hypoxic exposure. Yet growth of the epipodites (proposed respiratory structure) relative to mass (Y = aMb) was significantly reduced …

An Analysis Of First Amendment Jurisprudence And School Voucher Programs After Zelman V Simmons -Harris (2002), Lori A Stengel

UNLV Retrospective Theses & Dissertations

In a letter to the Danbury Baptist Association, Thomas Jefferson stated the need for a "wall of separation between Church & State." The Establishment Clause of the First Amendment maintained that metaphoric wall of separation; however, the magnitude of separation has varied over the course of time. The Supreme Court's holding in Zelman v. Simmons-Harris (2002) ushers in a new era of Establishment Clause interpretation; In Zelman, the Cleveland Scholarship and Tutoring Program faced an Establishment Clause challenge. An analysis of the Cleveland program illustrated that in the 1999--2000 school year, 82% of the participating private schools were religious in …

Cuba's Tourist Industry: Parallel Economies And Social Stratification, Marie Nathan Hummel Jan 2002

Cuba's Tourist Industry: Parallel Economies And Social Stratification, Marie Nathan Hummel

UNLV Retrospective Theses & Dissertations

International tourism has played an important role in unintended social changes in socialist countries. These social and cultural changes affect not only the economic, political and cultural genre of the government, but also of its citizens; This thesis asks the question, "Has the re-introduction of international tourism in Cuba diluted and compromised the egalitarian goals of the revolution"? I intend to show that the consequences of Cuba's emerging tourist industry has not only compromised the ideology of the revolution, but has in fact seen a return of a pre-revolution stratified society and parallel economies, one based on the peso and …

Personal Epistemology: Implications For Stress In College Students, Robyn M Johnson Jan 2002

Personal Epistemology: Implications For Stress In College Students, Robyn M Johnson

UNLV Retrospective Theses & Dissertations

This research study investigated whether college students' epistemological beliefs (i.e. certain knowledge, simple knowledge, fixed ability, quick learning, and omniscient authority) could predict negative stressors and/or reactions to stress in their college experience. Based on responses to two self-assessment inventories and a demographic survey; analysis of the data suggests that over and above contributions from demographics (i.e. gender, ethnicity, age, and education level), certain dimensions of epistemological beliefs contributed significantly to the prediction of negative stress in college students. This suggests that it is essential for educators to provide opportunities for students' epistemological development; specifically, in the area of constructing …

Negotiation And Autonomy In A Fast Food Restaurant, Eric Orion Silva Jan 2002

Negotiation And Autonomy In A Fast Food Restaurant, Eric Orion Silva

UNLV Retrospective Theses & Dissertations

This study is an attempt to apply the negotiated order perspective to the analysis of the lived experience of workers in two franchised fast food restaurants. Drawing primarily on the work of Anselm Strauss (1978) and D. H. J. Morgan (1975), I have examined data taken from auto-ethnographic and overt observation. I found that workers in different negotiation contexts would use implicit and explicit negotiation to achieve internal and external goals. Worker's negotiation strategies depended on the actor's individual proclivities and their interpretation of the negotiation context. Issues subject to negotiation included wages, the schedule, the amount of effort expended, …

Bench-Scale Modeling To Evaluate The Mechanical Effects Of Subsidence On A Monofill-Type Landfill Cover, Yuboon Tan Jan 2002

Bench-Scale Modeling To Evaluate The Mechanical Effects Of Subsidence On A Monofill-Type Landfill Cover, Yuboon Tan

UNLV Retrospective Theses & Dissertations

A bench-scale model was developed to simulate the effects of subsidence on compacted monofill-type landfill covers for the low-level radioactive waste landfills of the Radioactive Waste Management Sites of the Nevada Test Site. Of particular interest is the collapse mechanism of the cover with respect to the soil density and compaction water content. Collapse in covers compacted at lower water content was in the form of progressive upward caving by consistent raveling, with distinct, continuous preferential pathways for saturated fluid flow and vapor migration formed. (Abstract shortened by UMI.).
