Exploring The Relationships Between Rap And Hip-Hop Music Use And Objectified Body Consciousness, Body Dissatisfaction, And Gender Norms In Female Juvenile Delinquents, Nina Simone Brathwaite

UNLV Theses, Dissertations, Professional Papers, and Capstones

Various forms of portable media (e.g., television, movies, magazines, internet, music) are increasingly accessible to and used by the average adolescent in the U.S. (American Psychological Association [APA], 2007; Ward, 2003). Two of the most popular genres of adolescent entertainment, rap and hip-hop music are frequently criticized for their use of misogynistic images and lyrics that objectify women and glorify sex, drug use, and violence (Bretthauer, Zimmerman & Banning, 2006; Conrad, Dixon & Zhang, 2010; Ward, 2003). Although understudied, one could argue that increased accessibility to and use of such media that fosters sexually-explicit and -objectifying messages common in Western …

The Relationship Between Sex-Typing And Help-Seeking Behaviors In Adults, Joshua Juvrud

UNLV Theses, Dissertations, Professional Papers, and Capstones

The process of expressing what is masculine promotes attitudes and behaviors that can discourage men from seeking help, contributing to numerous health issues in males. The purpose of this study was to explore how personally endorsed gender stereotypes vs. gender stereotyped attitudes impacted help-seeking behavior. In the current study, female and male adults completed challenging puzzle tasks, recalled previous health help-seeking behavior, and completed sex-typed measures. Females utilized personally endorsed gender stereotypes more during the puzzle tasks, while males utilized both personally endorsed gender stereotypes as well as gender stereotyped attitudes. When males recalled health-related events, however, personally endorsed feminine …

The Effect Of Scaffolded Strategies On Content Learning In A Designed Science Cyberlearning Environment, Cynthia Lee Kern

UNLV Theses, Dissertations, Professional Papers, and Capstones

Scientific inscriptions--graphs, diagrams, and data--and argumentation are integral to generating and communicating scientific understanding. Scientific inscriptions and argumentation are also important to learning science. However, previous research has indicated that learners struggle to understand and learn science content represented in inscriptions. Furthermore, when learners engage in argumentation, learning science content becomes secondary to the learning of argumentation skills. This design-based research study is nested within the larger effort to inform the design and development of the 5-Featured Dynamic Inquiry Enterprise design framework (5-DIE) for cyberlearning environments and to advance theory associated with the difficulties learners have with scientific inscriptions and …

The Effect Of Temperature Extremes On Cardiorespiratory Function In The Grass Shrimp Palaemonetes Pugio: Oxygen Limited Thermal Tolerance, Teresa Mika

UNLV Theses, Dissertations, Professional Papers, and Capstones

Aquatic poikilothermic animals must either cope with or compensate for the mismatch in oxygen supply and demand present at high temperatures. Oxygen limited thermal tolerance explains how aerobic scope is limited by insufficient oxygen supply and sets the performance window in animals. This work explores the effects of temperature on the different components of the oxygen delivery system, in both normoxic and hyperoxic conditions to determine if supplying more oxygen to the system mitigates the effects of temperature effects on the cardiorespiratory system and extends oxygen limited thermal tolerance to higher temperatures. The effect of temperature and oxygen condition was …

Phosphorus Removal From Ebpr Sludge Dewatering Liquors Using Lanthanum Chloride, Aluminum Sulfate And Ferric Chloride, Michael Strileski

UNLV Theses, Dissertations, Professional Papers, and Capstones

In wastewater treatment, enhanced biological phosphorus removal (EBPR) is becoming an increasingly popular alternative to chemical precipitation (CP) because of its lower costs and reduced sludge production. However, downstream solids handling processes such as digestion, sludge storage and dewatering promote an undesirable release (i.e. secondary release) of polyphosphate that was stored within EBPR sludge. Released phosphate is recycled to the head of the plant with the liquors of sludge dewatering processes. The concentration of phosphate in recycle streams from EBPR systems can be one to two orders of magnitude higher than the influent phosphorus concentration entering the EBPR system. Plants …

Understanding Basin Specific Life History Characteristics Of Lake Mead Quagga Mussels (Dreissena Bugensis) And A Potential Treatment Using Uv Radiation In Laboratory Studies, Melissa Thaw

UNLV Theses, Dissertations, Professional Papers, and Capstones

The quagga mussel (Dreissena bugensis) is an aquatic invasive species that is spreading throughout Lake Mead and other western waterways. Unlike their native waters in Eurasia, Lake Mead exhibits year round warm temperatures, high calcium levels and a lack of natural predators, all of which are very favorable conditions for their growth and spread. Dreissena bugensis reproduce and colonize hard surfaces rapidly, where they filter large amounts of water. They disrupt the aquatic food chain and interfere with infrastructure that is exposed to lake water. There is an urgent need to understand Dreissena bugensis life history characteristics within this new …

Hippocampal Sclerosis Of Aging, A Prevalent And High-Morbidity Brain Disease, Peter T. Nelson, Charles D. Smith, Erin L. Abner, Bernard J. Wilfred, Wang-Xia Wang, Janna H. Neltner, Michael Baker, David W. Fardo, Richard J. Kryscio, Stephen W. Scheff, Gregory A. Jicha, Kurt A. Jellinger, Linda J. Van Eldik, Frederick A. Schmitt

Sanders-Brown Center on Aging Faculty Publications

Hippocampal sclerosis of aging (HS-Aging) is a causative factor in a large proportion of elderly dementia cases. The current definition of HS-Aging rests on pathologic criteria: neuronal loss and gliosis in the hippocampal formation that is out of proportion to AD-type pathology. HS-Aging is also strongly associated with TDP-43 pathology. HS-Aging pathology appears to be most prevalent in the oldest-old: autopsy series indicate that 5-30 % of nonagenarians have HS-Aging pathology. Among prior studies, differences in study design have contributed to the study-to-study variability in reported disease prevalence. The presence of HS-Aging pathology correlates with significant cognitive impairment which is …

Hemoglobin-Mediated Nitric Oxide Signaling, Christine C. Helms, D. B. Kim-Shapiro

Physics Faculty Publications

The rate that hemoglobin reacts with nitric oxide (NO) is limited by how fast NO can diffuse into the heme pocket. The reaction is as fast as any ligand/protein reaction can be and the result, when hemoglobin is in its oxygenated form, is formation of nitrate in what is known as the dioxygenation reaction. As nitrate, at the concentrations made through the deoxygenation reaction, is biologically inert, the only role hemoglobin was once thought to play in NO signaling was to inhibit it. However, there are now several mechanisms that have been discovered by which hemoglobin may preserve, control, and …

In Situ Quenching And Post-Polymerization Modification Of Telechelic Polyisobutylene, Todd Raymond Hartlage

Dissertations

Polyisobutylene (PIB) is a saturated hydrocarbon elastomer that can only be produced by cationic polymerization. The water-initiated, chain transfer controlled synthesis conducted on an industrial scale produces monofunctional PIB with mixed olefin end groups. Living cationic techniques produce mono- and di-functional telechelic PIB. In situ quenching is the process of adding functional molecules to the polymerization reactor after all monomer is consumed. These quencher species bond to the chain ends, installing their latent functionality onto the polymer chain. To date, all quenchers utilized have been soft π-nucleophiles.

In the first project, free thiols, both aromatic and aliphatic, are shown to …

Intangible Cultural Heritage In The Pacific Islands: Why Europe Should Listen In, Katharina Serrano

Pacific Studies

Pacific Island countries (PICs) are developing countries that represent one of the culturally richest and most diverse regions worldwide. A decade ago, the realization evolved at the international level that intangible cultural heritage (ICH) represents a development tool with an inherent commercial value. Regional initiatives are currently trying to balance objectives of development and protection of ICH with the need for commercial exploitation and effects of commodification. Yet the same cannot be said about the Economic Partnership Agreement (EPA) between PICs and the EU. This article advocates that current efforts by the European Union (EU) in supporting regional and national …

Traditional Knowledge And Patents: A Brief Summary Of The Epo's Perspective, Enrico Luzzatto

Pacific Studies

Knowledge of the legal provisions of the European Patent Convention (EPC) relevant to traditional knowledge (TK ) is essential to TK holders such as in Pacific Island countries so that they can actively protect in Europe any TK-derived invention they may want to develop. It is also of fundamental importance to be able to properly defend their rights if a European patent application that could be based on their TK is filed without their consent. This paper introduces the role and structure of the European Patent Office (EPO) and basic legal requirements, as set out in the EPC, that are …

Protecting Nature And Culture: Enhancing Legal Frameworks For The Conservation Of Heritage In The Pacific, Erika J. Techera

Pacific Studies

It is well recognized that for Pacific Island peoples, nature and culture are inextricably linked. The protection of the natural environment and biodiversity, for example, are essential for the maintenance of traditional and contemporary lifestyles and cultures. Conversely, many aspects of Pacific intangible heritage, including traditional knowledge, are inherently associated with natural resources. Therefore, in this context, the protection of nature and culture cannot be separated. More broadly, the preservation of the unique biological and cultural diversity of this region is of importance for all people. The significance extends beyond ensuring cultural integrity and environmental health to providing a possible …

Food Security In Pacific Island Countries, Sue Farran

Pacific Studies

This paper considers the advantages, disadvantages, and challenges confronting the use of intellectual property regimes in the context of food security. While there has been some shift in agricultural practices, subsistence cultivation remains an important aspect of the daily lives of many Pacific Islanders and reflects traditions that for centuries have preserved biodiversity and provided a buffer against crops failures and food loss caused by natural disasters. Climate change, population growth, the cost of imported foods, and loss of traditional knowledge mean that many of these aspects of food security are under pressure. Intellectual property regimes which result in disease-resistant …

Music In Traditional Exchanges In North Vanuatu, Monika Stern

Pacific Studies

Music is a social phenomenon all owing the possibility of indefinite recreations. Depending on the cultures, places, and times, musical exchanges have been locally managed in various ways. Today the tights to copy a particular music are a sensitive topic of current international interest because of the development of the music industry. In Vanuatu custom, a principle close to the concept of intellectual property rights has existed for centuries for music or other intangible knowledge. Traditionally, not everyone has the right to hand over certain parts of this knowledge; complex rules must be observed. Although for most sets of music …

An Examination Of The Effects Of Land Use And Land Cover On Macroinvertebrate Communities At Two Landscape Scales, Tanya Sulikowski

Theses, Dissertations and Culminating Projects

Macroinvertebrate community composition and differing patterns of land use/ land cover (LULC) were assessed in three watersheds of northern New Jersey. A total of six 40-m reaches were sampled in the agriculturally dominated Wallkill, the urbanized Rockaway and the forested Flat Brook. Qualitative observations and scorings of ten habitat factors commonly associated with stream health and water quality were made at each site. These Habitat Assessments resulted in the two Flat Brook sites being rated as “optimal” and the remaining four sites being rated as “suboptimal”. The 2007 NJDEP Land Use/Land Cover (LULC) dataset was used to determine percent urban, …

Smart Superhydrophobic Materials, Adetoun Taiwo

Theses and Dissertations

Superhydrophobicity refers to surfaces with extremely large water droplet contact angles (usually greater than 150°). This phenomenon requires a hydrophobic material with micro or nano-scale roughness. Superhydrophobic surfaces exist in nature (e.g. the lotus leaf) and can be produced synthetically. This project focuses on the development and characterization of superhydrophobic materials with tunable wettability (i.e. smart superhydrophobic materials). In this study, surfaces were prepared by electrospinning thin, aligned polystyrene fibers onto a piezoelectric unimorph substrate. Results showed electric field induced changes in substrate curvature, which produced corresponding changes in surface wettability. From experiments, an average change in water contact angle …

Sharing: Social Behavior In Situations Of Risk, Stephanie Theresia Stilling

Dissertations

The present study will experimentally investigate human cooperation (sharing) in a laboratory foraging task that simulates environmental variability and resource scarcity (shortfall risk). Specifically, it investigates whether a risk-reduction model of sharing developed by evolutionary biologists (derived from a risk-sensitive optimization model known as the energy-budget rule) could predict human cooperative behavior. Participants respond to earn points exchangeable for money when point gains were unpredictable. Failures to acquire sufficient points result in a loss of accumulated earnings (a shortfall). Participants are given the choice between working alone or working with others. The difficulty of meeting the earnings requirement is manipulated …

Exploring Adolescent Experiences Of Race, Ethnicity, And Socioeconomic Status In Counseling Relationships: A Qualitative Approach, Christina Crans

Dissertations

The ACA Code of Ethics (2005) states the expectation that counselors must understand the diverse backgrounds of their clients. In addition, counselors are called to understand how their personal cultural identity informs and affects the counseling process. Yet there is paucity in the literature regarding the multicultural client experience within a counseling relationship. Of the few multicultural counseling studies that attempt to address multicultural client concerns, the approach has been quantitative or reliant on counselor self-report. In addition, the lived counseling experiences of adolescents and individuals from lower socioeconomic status (SES) is absent in present literature. This qualitative study examined …

The Characterization Of Algae Grown On Nutrient Removal Systems And Evaluation Of Potential Uses For The Resulting Biomass, Kristin Hampel

Dissertations

Eutrophication resulting from excess nutrient loads is a major environmental issue that affects surface water quality and causes surplus primary production, thereby reducing dissolved oxygen concentrations. A method for managing nutrients in surface waters involves absorption of excess nutrients by deliberately cultivating benthic algal turf biomass, then harvesting it for a variety of uses, including biofuels, soil amendments, or feed supplements, thus coupling nutrient removal to additional economic drivers.

The goals of this work are to (1) evaluate the composition of algal biomass grown to remove surface water nutrients, (2) compare biomass grown at different geographic locations and in dissimilar …

Population Demographics And Genetics Of Spix's Disk-Winged Bat: Insights Regarding Survival, Mate Choice, Gene Flow And Effective Population Size, Michael Buchalski

Dissertations

Simultaneous study of the demographics and genetics of populations are relatively rare within the literature, despite insights their combined use offers regarding the life history, ecology, and evolution of species. Here I take a comprehensive approach, using capture-recapture data, polymorphic microsatellite markers, and various modeling techniques to examine the demographics and genetics of multiple local populations of Spix’s disk-winged bat (Thyroptera tricolor) in southwestern Costa Rica. T. tricolor is a highly gregarious, neotropical bat species known to form kin-based social groups with high retention of offspring of both sexes. The implications of this highly unusual social structure for …
