Associations Among Benevolent Sexism, Relationship-Contingent Self-Esteem, And Relationship Maintenance Strategies In Heterosexual Women, Carrie Underwood Dec 2017

Associations Among Benevolent Sexism, Relationship-Contingent Self-Esteem, And Relationship Maintenance Strategies In Heterosexual Women, Carrie Underwood

UNLV Theses, Dissertations, Professional Papers, and Capstones

Past research shows that heterosexual women who endorse benevolent sexism (a sex-role attitude) tend to be highly invested in romantic relationships (Lee, Fiske, Glick, & Chen, 2010). Consequently, they may be more likely than other women to remain in relationships that are troubled. The current study aimed to shed light on this possibility by examining whether benevolent sexism was associated with the relationship maintenance strategies that women use in troubled relationships. I presented women with a scenario of a troubled relationship and manipulated the type of sexism the male partner in the scenario endorsed. Repeated measures ANCOVA revealed that women …

Worked To Leisure: The Intersections Of Volunteerism, Work, And Leisure, Denise Nicole Cook Dec 2017

Worked To Leisure: The Intersections Of Volunteerism, Work, And Leisure, Denise Nicole Cook

UNLV Theses, Dissertations, Professional Papers, and Capstones

Volunteerism and work are topics which academics in several disciplines research. This study is an examination of the intersection of work and volunteerism via the lens of role theory. According to role theorists, the term role refers to behaviors which are either a result of social position or expectations (Biddle 1986). Cognitive role theorists use vocabulary such as “role conflict” and “role overload” to identify incongruences sometimes found in roles individuals have in their lives (Biddle 1986). These incongruences are primarily examined as they relate to individual level consequences. This research explores volunteerism and work as they relate to role …

Sex Worker And Proud: A Phenomenological Study Of Consensual Sex Workers' Lives, Michael Gerald Curtis Jr. Dec 2017

Sex Worker And Proud: A Phenomenological Study Of Consensual Sex Workers' Lives, Michael Gerald Curtis Jr.

UNLV Theses, Dissertations, Professional Papers, and Capstones

Ten consensual sex workers who were currently working in Nevada were qualitatively interviewed in an effort to explore their perceptions of the adult industry. Interviews specifically focused on their experience disclosing their profession to others and the potential effects that it has on their personal relationships, and access to effective treatment. The Moustakas method of phenomenological inquiry was used to analyze data from ten participants who self-identified as direct sex workers. Seven essential themes emerged from this analysis: (1) the adult industry provides professional and personal agency, (2) the industry is often transient, (3) disclosure is an impactful and ongoing …

Complete Sequencing And Comparative Analysis Of The Genomes Of The First Magnetotactic Gammaproteobacteria Isolated In Pure Culture: Strains Bw-2 And Ss-5, Corey Geurink

UNLV Theses, Dissertations, Professional Papers, and Capstones

The genomes of the first two discovered magnetotactic bacteria (MTB) belonging to the ammaproteobacteria, strains BW-2 and SS-51, were sequenced, sealed, annotated and compared to MTB of other phylogenetic groups. Cells of both strains are rod-shaped and biomineralize cuboctahedral and elongated octahedral crystals of magnetite, respectively, that are enveloped in a protein-embedded, lipid-bilayer membrane referred to as the magnetosome membrane or vesicle. The crystals and their associated membranes are known as magnetosomes. Magnetosome crystals consist of either magnetite (Fe3O4) or greigite (Fe3S4) and, because of their specific mineral compositions, crystal morphologies and sizes, the biomineralization processes involved in magnetosome formation …

The Effect Of Oil Prices On Workforce In Selected Organization For Economic Cooperation And Development (Oecd) Countries, Amjad Kisswani Dec 2017

The Effect Of Oil Prices On Workforce In Selected Organization For Economic Cooperation And Development (Oecd) Countries, Amjad Kisswani

UNLV Theses, Dissertations, Professional Papers, and Capstones

Oil prices have greatly increased and decreased over the past few years, and have constantly been responsible for causing undesirable world economic performance and employment effects. The increase of oil prices usually leads to the rising prices of services such as production costs, energy bills, and petroleum products. Therefore, the increase will lower the productivity level, which affects interest rates and inflation rates, investments, product selling prices, consumption levels, unemployment rates, and real wage rates (Loungani, 1986). The oil price shocks since the 1970s have had a significant impact on the economy and are considered an important element of economic …

Persistence Of Escherichia Coli O157:H7 And Listeria Monocytogenes On The Exterior Of Common Packaging Materials, Duleeka Prasadani Kuruwita Arachchige Dec 2017

Persistence Of Escherichia Coli O157:H7 And Listeria Monocytogenes On The Exterior Of Common Packaging Materials, Duleeka Prasadani Kuruwita Arachchige

All Theses

Acute gastroenteritis (AGE), a major cause of illness, results in 179 million AGE cases every year in the United States. AGE bacteria that have low-infectious dose include E. coli O157:H7 (<10-100 cells) and L. monocytogenes (<1000 cells). Because of their low-infectious dose and high environmental resistance, contaminated surfaces, such as the exterior surface of food packages, could be a source for disease transmission. Our aim was to determine the persistence of E. coli O157:H7 and L. monocytogenes on three packaging materials - oriented polyethylene terephthalate (OPET), oriented polypropylene (OPP), and nylon-6. Coupons (25 cm2) from each material were sterilized under ultraviolet light for 5 minutes. Spot and spread inoculation was done on treatment coupons with ca. 7 log CFU of a 3-strain-mixture of green fluorescent protein (GFP)-labeled E. coli O157:H7. All the coupons were incubated at Technical …

Manuscripts, Articles, Book Chapters and Other Papers

Secondary hyperparathyroidism (SHPT) is a rare complication of furosemide therapy that can occur in patients treated with the loop diuretic for a long period of time. We report a 6-month-old 28-weeks premature infant treated chronically with furosemide for his bronchopulmonary dysplasia, who developed hypocalcemia and severe SHPT, adversely affecting his bones. Discontinuation of the loop diuretic and the addition of supplemental calcium and calcitriol only partially reversed the SHPT, bringing serum parathyroid hormone level down from 553 to 238 pg/mL. After introduction of the calcimimetic Cinacalcet, we observed a sustained normalization of parathyroid hormone concentration at 27 to 63 pg/mL …

Communicating Seismic Risk: The Geoethical Challenges Of A People-Centred, Participatory Approach, Is Stewart, J Ickert, R Lacassin Dec 2017

Communicating Seismic Risk: The Geoethical Challenges Of A People-Centred, Participatory Approach, Is Stewart, J Ickert, R Lacassin

School of Geography, Earth and Environmental Sciences

The Sendai Framework for Disaster Risk Reduction (SFDRR) encourages scientists to participate in bottom-up risk communication approaches that directly engage hazard-prone populations. Effective communication of seismic risks not only has economic impacts in terms of hazard mitigation but also provides social value in potentially empowering the marginalized populations that disproportionately live in high-risk areas. This emphasis on community-focused disaster preparedness, however, presents a novel set of communication challenges for geoscientists. Few scientists have training in or experience of translating their science for lay publics, and conveying complex risk information is especially difficult in circumstances where scientific issues are socially contested …

The Impact Of Researchers’ Perceptions Of Insecurity And Organized Crime On Fieldwork In Central America And Mexico, Dawid K. Wladyka, William Yaworsky Dec 2017

The Impact Of Researchers’ Perceptions Of Insecurity And Organized Crime On Fieldwork In Central America And Mexico, Dawid K. Wladyka, William Yaworsky

Sociology Faculty Publications

This article explores field researchers’ perceptions of field site security and causes of fieldwork disruption. We seek to quantify what phenomena are decisive in perceiving a field site insecure and to gauge whether researchers find rural or urban areas to be more secure from organized criminal violence. We also identify the conditions that best predict scholars’ willingness to abandon research in any given region. To do so, we use a regression analysis of the results of a survey administered to anthropologists working in Mexico and Central America. The article reveals that anthropologists view urban areas as being less secure and …

Evaluation Of A Direct Pcr Method And The Qiagen Investigator 24plex Go! Kit For Typing Blood, Saliva And Touch Dna On Multiple Substrates, Angelita Pierre-Noel

Student Theses

In forensic DNA typing, omitting the DNA extraction procedure and adding the sample directly to the polymerase chain reaction (direct PCR) mixture has several advantages. Without extraction and purification, there is less of a risk of sample loss, sample mix up, or contamination. This study tested the feasibility of direct PCR using the Qiagen® Investigator® 24plex GO! Kit, a megaplex kit that amplifies 22 polymorphic STR markers and the Amelogenin sex determination alleles. Test samples included blood, saliva and skin cells on porous substrates, specifically denim, white cotton, polyester fabric, and paper tissue. Glass slides were used to represent non-porous …

The Growth, Structure, And Dynamics Of Crime In Cities, Marcos Oliveira Dec 2017

The Growth, Structure, And Dynamics Of Crime In Cities, Marcos Oliveira

Theses and Dissertations

Crime is ubiquitous in cities but lacks a statistical characterization that could lead to uncovering its underlying mechanisms. Cities are, however, in a constant process of organization making difficult to analyze urban phenomena. Yet, to understand urbanization and its consequences, we need to approach cities as evolving processes, instead of static objects. With this perspective, we examined regularities in crime regarding its growth, structure, and dynamics. We developed frameworks to examine the spatial, temporal, and periodic variations of crime in cities. Though thefts increase super-linearly with the population, we found burglaries showing a linear increase. Our analyses also confirmed crime …

Physical Aggressiveness And Gray Matter Deficits In Ventromedial Prefrontal Cortex, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall Dec 2017

Physical Aggressiveness And Gray Matter Deficits In Ventromedial Prefrontal Cortex, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall

Psychology Faculty Publications

What causes individuals to hurt others? Since the famous case of Phineas Gage, lesions of the ventromedial prefrontal cortex (VMPFC) have been reliably linked to physically aggressive behavior. However, it is unclear whether naturally-occurring deficits in VMPFC, among normal individuals, might have widespread consequences for aggression. Using voxel based morphometry, we regressed gray matter density from the brains of 138 normal female and male adults onto their dispositional levels of physical aggression, verbal aggression, and sex, simultaneously. Physical, but not verbal, aggression was associated with reduced gray matter volume in the VMPFC and to a lesser extent, frontopolar cortex. Participants …

A Context-Free Method Of Visualizing Streaming Object Data For The Purpose Of Identifying Known Events: An Implementation And Analysis, Quinn Gregory Carver Dec 2017

A Context-Free Method Of Visualizing Streaming Object Data For The Purpose Of Identifying Known Events: An Implementation And Analysis, Quinn Gregory Carver

Theses and Dissertations

This year, every second, five gigabytes of new data will be streamed to storage and yet less than half a percent of all this data will ever be analyzed. Much of this muted data is high-variety object data, unnoticed in a void of sorely needed tools to make it readily understandable. A software tool for visualizing streaming object data in a context-free manner can be built, and this tool would aid in finding predictor data for known events which are functions of the data. The design of the tool to support the hypothesis is presented and field results from over …
