Brothels In The Marketplace Of Ideas: Toward A Heuristic Definition Of Commercial Speech, Marc S. Charisse

UNLV Retrospective Theses & Dissertations

Nevada's legal brothels offer a unique opportunity to study the problem of defining commercial speech. Although state law forbids advertisements of houses of prostitution in counties where brothels themselves are against law, brothel messages are abundant in Clark County, where any form of prostitution is illegal. The publishers of these messages claim they are constitutionally protected editorial speech rather than advertisements which enjoy little or no First Amendment protection, thus confounding the efforts of prosecutors who say they would otherwise move to remove such messages from public display; The thesis examines the development of the U.S. Supreme Court's commercial speech …

Stress Management In Las Vegas Municipal Court, Robert Clinton Zangger

UNLV Retrospective Theses & Dissertations

An analysis of the effectiveness of Las Vegas Municipal Court's stress management workshop was conducted. The State-Trait Anxiety Inventory was given to fifty one volunteers prior to and after a stress management workshop. Of the 51, seven participated in a four hour workshop given in two sessions. Those attending the workshop had elevated stress scores after the workshop. Exposure to the symptoms of stress without adequate follow-up on how to treat the symptoms may have led to the unexpected result. It is on the basis of these findings that future workshops concentrate on identifying stress related symptoms as well as …

Sedimentological Constraints On Middle Miocene Extensional Tectonism Of The Southern Las Vegas Range, Southern Nevada, Jack Edward Deibert

UNLV Retrospective Theses & Dissertations

A depositional-tectonic model is proposed for the reconstruction of a Miocene lacustrine basin in the southern Las Vegas Range, Nevada, that was fragmented during a period of extensional tectonism. The model suggests that the sediments were deposited in an isolated basin during initiation of normal faulting in the Sheep Range extensional allochthon 12 to 16 Ma. After 12 Ma, deposition in this basin was terminated by normal faulting followed by oroflexural rotation along the Las Vegas Valley shear zone; The unique Middle Miocene sequence is 335-m-thick and consists of interbedded nonmarine limestone, siltstone, sandstone, conglomerate, megabreccia, and volcanic ash. The …

Pms: Cyclical Variation In Attentional Capacity With Pms And Non-Pms Women, Francine Linda Greenstein

UNLV Retrospective Theses & Dissertations

The increasing need for women to have an expanded role in decision making capacities and in professional areas raises persistent questions concerning the effect of menstrual cycle fluctuations on performance, specifically, cognitive/intellectual functioning. A wide variety of recurring cyclical and emotional symptoms have been reported as common to women suffering from premenstrual syndrome (PMS). This study examined possible impairment of cognitive functioning during the PMS phase of the menstrual cycle using PMS and Non-PMS women. The two groups were compared over three menstrual cycles on a digit span task, a letter detection task, and a combination of the two. PMS …

Late Holocene Earthflows Of The Willard Playa/Dune Complex, Estancia Valley, New Mexico; A Geomorphic Response To Climatic Change, Kurt A Goebel

UNLV Retrospective Theses & Dissertations

Late-middle to late Holocene dune sediment that overlies Pleistocene lacustrine sediment marks the onset of xeric conditions in the Estancia Valley, central New Mexico. Incised into the underlying lacustrine sediments, the modern deflation basins are enclosed by parabolic dunes composed of clay and gypsum derived from the underlying sediment; Located on the in-facing duneslopes of the deflation basins, the most striking geomorphic feature of this dune complex are numerous elongated scars. These relict scars document a geomorphically distinct earthflow event. Arroyos that cut into flow scars expose eolian earthflow sediment overlying lacustrine deposits. In the zone of depletion, erosional-flow evidence …

The Effects Of A Twelve Week Exercise Program On Fitness Levels And Blood Glucose Of Type Ii Diabetics And Overweight Individuals, Susan Darlene Iverson

UNLV Retrospective Theses & Dissertations

This study compared body composition, cardiovascular capacity, flexibility, muscular strength and endurance, and blood glucose of type II diabetics to overweight, nondiabetics participating in a 12 week endurance training program. Five type II diabetics, ages 52 to 67, were compared to eight overweight nondiabetics, ages 18 to 66. The "Y's Way to Physical Fitness" battery of tests was used throughout (Golding et al., 1982). Blood glucose was measured with a portable meter using a finger prick and sterile, disposable lancet. Using a correlated t-test (p {dollar}<{dollar}.005), the following variables were analyzed to determine if there were significant differences in fitness after training: weight, percent body fat, resting heart rate, flexibility, one-minute recovery heart rate, bench press, situps, VO2 max, and PWC max. A univariate F-test was used in a one-way analysis of variance (p {dollar}<{dollar}.05) to compare mean individual group differences on fitness measures after training.

Braided Stream Deposition And Provenance Of The Late Cretaceous-Paleocene(?) Canaan Peak Formation, Table Cliff And Kaiparowits Plateaus, Southwestern Utah, David Allen Jones

UNLV Retrospective Theses & Dissertations

The Late Cretaceous to Paleocene(?) Canaan Peak Formation of southwestern Utah is comprised of approximately 100 m of cobble conglomerate and subordinate sandstone. Gravel deposition occurred during high-discharge periods within a Scott-type, perennial, braided fluvial system as longitudinal (Gm) and sinuous-crested transverse (Gt) bars, and as a product of longitudinal bar-top and inter-bar channel scour filling (Gt). Sand accumulated under lower flow velocity conditions through migration of inter-bar channel dunes and transverse bars (St/Sp) and development of scour-and-fill deposits (Ss). Siltstone (Fm) deposition resulted from vertical accretion on bar tops during waning flow conditions; Clast imbrication and trough axis orientation …

Fish Aid: The Lake Mead Fertilization Project, Richard Axler, Larry Paulson, Peter Vaux, Patrick Sollberger, Donald H. Baepler

Publications (WR)

Sport fishing at Lake Mead in Nevada and Arizona is a resource valued at nearly $100 million per year to southern Nevada. During the past two decades, salmonids, mostly trout, have disappeared entirely, the largemouth bass catch has drastically declined despite greater fishing pressure, and the condition factors for striped bass have steadily deteriorated. It appears that a major reduction in phosphorus loading caused by the upstream impoundment of the Colorado River to form Lake Powell in 1963 and advanced wastewater treatment removal of phosphorus from domestic wastewater inflows in 1981 are the principal factors responsible for decreased production at …

Changes In The Morphometry Of Las Vegas Wash And The Impact On Water Quality, Richard A. Roline, James J. Sartoris, U.S. Bureau Of Reclamation

Publications (WR)

Las Vegas Wash, a natural wash east of Las Vegas, Nevada, carries stormwater, groundwater drainage, and sewage effluent from two sewage treatment plants to Lake Mead. Over 80 percent of the normal discharge of approximately 3.4 m³/s (120 ft³/s) consists of effluent from the City of Las Vegas and Clark County sewage treatment plants. Beginning in the 1950s, a large wetland area developed along the wash that supported waterfowl populations and contributed to some water quality transformations. Heavy rains and subsequent flooding in the area in 1983 and 1984 resulted in erosion and channelization that greatly …

Lake Mead Prefertilization Study: Preliminary Nutrient Enhancement Studies In Lake Mead, Richard P. Axler, Larry J. Paulson, Patrick J. Sollberger, Donald H. Baepler, U.S. Bureau Of Reclamation

Publications (WR)

Studies conducted by the University of Nevada-Las Vegas (UNLV), the Nevada Department of Wildlife (NDOW), the Arizona Game and Fish Department (AGFD), The Nevada Division of Environmental Protection (NDEP), and the United States Bureau of Reclamation (USBR) have identified decreased algal production as a major factor involved in the decline of the Lake Mead sport fishery. Phosphorus-laden silt particles in the Colorado River have been sedimenting out in Lake Powell since the completion of Glen Canyon Dam 286 miles upstream in 1963. This sharp decrease in phosphorus loading to Lake Mead (>5000 tons per year) has resulted in decreased …

Thermal Tolerances And Preferences Of Fishes Of The Virgin River System (Utah, Arizona, Nevada), James E. Deacon, Paul B. Schumann, Edward L. Stuenkel

Publications (WR)

Critical thermal maxima (CTM) and thermal preferenda of the common fishes of the Virgin River were examined. Differences in final temperature preferenda and CTM for species with low thermal lability (speckled dace, spinedace, roundtail chub) correspond well with differences in their distribution and abundance in the river. These species shifted their acute thermal preferences relatively little as acclimation temperature increased. For thermally labile species (woundfin, red shiner, desert sucker, and fiannehnouth sucker), the final preferendum is a less precise indicator of probable distribution. The woundfin, an endangered fish, has a high CTM (39.5 C at 25 C acclimation) and a …

Women And Aids: The Future Is Grim, Mary E. Guinan, Ann Hardy

School of Public Health Faculty Research

Recently, we analyzed the reported cases of acquired immunodeficiency syndrome (AIDS) in women in the United States.1 We found two areas of great concern: first, women are more likely than men to acquire AIDS through heterosexual intercourse, and second, women are the source of disease for about 80% of children with AIDS. In this column we will discuss the source and distribution of AIDS in women, and in a future piece we will discuss women as the source of infection for pediatric AIDS cases.

Analysis Of The Water-Quality Standards Proposed By The Nevada Division Of Environmental Protection, City Of Las Vegas, Nevada

Publications (WR)

The Nevada Division of Environmental Protection (DEP) has proposed water-quality standards, applicable to Las Vegas Bay and Lake Mead, for (1) chlorophyll, (2) un-ionized ammonia, and (3) pH.

We have concluded that the proposed standards are unlikely to protect or improve water quality in Lake Mead. The proposed chlorophyll standard:

May harm the fishery. Lakes with more chlorophyll have greater fish production.

Will not improve clarity. Chlorophyll concentrations above 30 ug/1 have little effect on clarity.

Will not protect against scums or dominance by blue-green algae. Lake Mead shows no consistent relationship between chlorophyll and scums or blue-green dominance.

Will …

Osteoporosis And Ert--The Jury Is Still Out, Mary E. Guinan, Karen Steinberg, Lambertina Freni-Titulaer

School of Public Health Faculty Research

Bone loss in women accelerates immediately after menopause, often leading to osteoporosis and an increased risk of bone fractures. In 1985,247,000 hip fractures occurred in people over 45 years of age. Among those who live to be 90, one-third of women and one-sixth of men will experience hip fractures. Six months after fracture, 25% of victims will not be able to carry out their usual activities, and 50% will need assistance to do so. Hip fractures are not only a serious cause of morbidity but they also increase the risk of mortality in older people. Because the proportion of the …
