Expanding The Definition Of Provenance: Adapting To Changes Since The Publication Of The First Aam Guide To Provenance Research, Katlin Cunningham

Master's Projects and Capstones

In 2001 the American Alliance of Museums (AAM) published The AAM Guide to Provenance Research. However, in the past seventeen years there have been several new developments in the provenanceresearchfield, and an updated guide has yet to be released. I propose that several changes be made to create an updated version. For this project, I tested this guide in two ways: first, to see how our understanding of provenance has changed since 2001 and second, to use a case study to assess whether the recommended basic research guide and principles still apply to today.

In the first …

The Relationship Between Challenge Courses And The, Christopher Luna

Health, Exercise, and Sports Sciences ETDs

There has been an increasing demand among education agencies to utilize challenge courses, also known as ropes courses, for personal growth opportunities among students of all ages. Teachers often tell students how they want students to work as a “team” and “get along” without providing the experiences for them to practice such behaviors. A low ropes experience allows students to practice cooperative skills. The focus of garnering participants for this study was to identify a specific target of first-generation college students from two separate classroom settings. The research focused on identifying the relationship between first-generation college students and low ropes …

Triple Sulfur Isotope Relationships During Sulfate-Driven Anaerobic Oxidation Of Methane, Shanggui Gong, Yongbo Peng, Huiming Bao, Dong Feng, Xiaobin Cao, Peter W. Crockford, Duofu Chen

Faculty Publications

© 2018 Elsevier B.V. Sulfate-driven anaerobic oxidation of methane (SD-AOM) plays a critical role in regulating the global methane budget. Determination of the diagnostic triple isotope exponent θ33 (≡ln33⁡α/ln34⁡α) for SD-AOM can help to identify and quantify microbial sulfate reduction via SD-AOM in the environment. The history of Earth's surface redox conditions can also be examined through the measurement of triple sulfur isotope compositions in sedimentary rocks. Due to difficulties in both culturing anaerobic methanotrophs and sampling pore-water sulfate in SD-AOM-dominated environments, however, the θ33 values for the processes of SD-AOM have not been constrained. We propose that a set …

When Art Becomes Political: An Analysis Of Irish Republican Murals 1981 To 2011, Maura Wester

History & Classics Undergraduate Theses

For nearly thirty years in the late twentieth century, sectarian violence between Irish Catholics and Ulster Protestants plagued Northern Ireland. Referred to as “the Troubles,” the violence officially lasted from 1969, when British troops were deployed to the region, until 1998, when the peace agreement, the Good Friday Agreement, was signed. Despite the changes in the government system, two things have not changed in Northern Ireland since the Good Friday Agreement: the pride both Loyalists and Republicans have in their cultures and their means to express this: murals. Traditionally a Loyalist practice dating back to late 1920s, Republican murals did …

The Dominican Liberator: Father Edward Paul Doyle, O.P.’S Response To The Holocaust, Jacqueline Michels

History & Classics Undergraduate Theses

Individual survivors and witnesses to the Holocaust each remember and reflect on their experiences differently. Some are angry at the Nazis for their inhumane actions. Some are angry at God for allowing these evils to take place. Others learned from their experience. Edward Paul Doyle, O.P. was one of the latter. A Dominican Friar at Providence College, he served as an army chaplain for the United States Army in Germany during World War II. While in Germany, Father Doyle helped to liberate Nordhausen concentration camp where he witnessed the horrors of the Holocaust. Father Doyle recorded his experience and reflections …

Contemptible Cravens And Dumb Beasts: The Story Of The Wiggans Patch Massacre, Kevin Cranney

History & Classics Undergraduate Theses

On the evening of December 9, 1875, around forty masked men broke into the boardinghouse of the elderly widow Margaret O’Donnell in Wiggans Patch, a mining town outside of Mahanoy City, and killed her pregnant daughter and her son, an alleged Molly Maguire. The perpetrators of the Wiggans Patch Massacre literally got away with murder. One of the most brutal crimes of a particularly violent era was soon forgotten, especially when the Molly Maguire trials began the following month. How did this happen? Why was the Wiggans Patch Massacre forgotten when within the next few years (1876-1879) twenty men were …

Factors That Impact Direct Democracy And Voter Turnout: Evidence From A National Study On American Counties, Michael Joseph Biesiada

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation examines factors that impact citizen initiatives and voter turnout. The dissertation contains two parts that build upon each other with fitting theoretical frameworks. The first part investigates the decision for a county government to permit citizen initiatives. This part applies new institutionalism theory as a framework to examine county governance, autonomy, and decision-making. County governments play a vital role in American politics, yet little is known about why some counties permit citizen initiatives while others do not. I address a gap in the literature that focuses on policy outcomes that vary at the county-level due to election laws. …

Examining The Training Transfer Practice Of A Financial Institution: An Action Research Study, Maria Lourdes Lourdes Gutierrez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Many organizations rely on training to improve the skills and knowledge of its human resources. The underlying assumption is that employees will use what they learned when they return to the workplace. Although there is evidence that learning occurred it does not always result in transfer (Mosel, 1957). Transfer is an issue of concern for training practitioners. If despite the significant investment no return is realized, then the training is not effective and the investment is wasted. This action research study was conducted in a financial institution in the Southwestern United States. The purpose of this study was to (1) …

Supranational Identity Politics: Sovereignism In The Eu, Emilio Jacintho

UNLV Theses, Dissertations, Professional Papers, and Capstones

The implementation of identity politics policies conceived at a supranational level appears to motivate the coordination of populist movements, the radicalization of their discourses, and an increasing resentment towards minority groups. I investigate the reaction of populist sovereignist political movements, among recently admitted EU member states, to the implementation of European Union policies that involve the positive discrimination of minority groups and mandated refugee relocations. The implementation of such policies seems to have contributed to the resentment toward policy-favored minorities, the increase of anti-immigration values, the success of extremist political expressions, and the mistrust of political institutions and traditional parties. …

The Effectiveness Of State Ethics Commissions On Curbing Corruption And The Effect Of Corruption On State Economic Performance, Anthony J. Prato

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation investigates the effectiveness of anti-corruption policies implemented across the United States that significantly reduce public sector corruption. In addition to the normative desire to combat corruption, it documents, the economic impact that corruption has on each state's per capita gross domestic product. To investigate public sector corruption articles between the years 2010 – 2015were reviewed for news stories that report on public sector corruption at the state level and below. The practical implications of this dissertation, if incorporated into a state level anti-corruption policy, could be used to reduce public sector corruption and increase that states' economic health. …

Petrogenesis Of Enriched And Intermediate Poikilitic Shergottites: From Magmatic Source To Emplacement, Rachel Rahib

UNLV Theses, Dissertations, Professional Papers, and Capstones

Poikilitic shergottites, making up >20% of martian meteorites, likely represent a significant composition of the martian crust, as intrusive gabbroic rocks. To further constrain petrogenetic relationships amongst enriched and intermediate poikilitic shergottites, we utilize bulk rock trace element compositions, mineral major element compositions, phosphorus maps of olivine grains, oxygen fugacity (ƒO2) values, subsolidus equilibration temperatures, and quantitative textural analyses, of the most comprehensive suite of poikilitic shergottites yet (11 samples), including three newly recovered samples (Northwest Africa [NWA] 11065, NWA 11043, NWA 10961). Although petrographically light rare earth element (LREE) enriched and intermediate poikilitic shergottites are similar, distinct LREE abundances …

The Impacts Of Acculturation Patterns And Processes On Immigrants' Success In Higher Education: A Multiple Case Study Of 1.25-Generation Third-Wave Iranian Immigrants To The United States, Fereshteh Rezaeian

UNLV Theses, Dissertations, Professional Papers, and Capstones

The United States of America is inherently a pluralistic society composed of various groups of immigrants. As scholars (Camarota & Zeigler, 2016; Gibson, 1998) state, the number of immigrant children accounts for 20% of the total number of school-age children. Despite all attempts to provide the best education to such a great number of immigrant students, the achievement gap between immigrant and non-immigrant students still exists (Baum & Flores, 2011; Rong & Preissle, 2008). Some scholars (e.g., Ramos & Sanchez, 1995) have proposed that the key factor for immigrants to be successful in the United States is to adapt to …

Why Musical Groove Makes Us Move: An Electroencephalographic Investigation, Samantha Reina O'Connell

UNLV Theses, Dissertations, Professional Papers, and Capstones

Moving to the groove of the music is a phenomenal and universal human behavior. Common characteristics to most dance music include a salient beat, rhythmic complexity, and a dynamic musical structure. What is unknown, however, is why music has the power to promote physical movement. Musical rhythm and motor processing are tightly linked activating brain areas important for motor preparation and execution. While studies demonstrate that the motor system is active during beat processing, it is still unclear how musical groove, a beat-influenced quality to music that makes us want to move, can engage these motor areas. Here, I performed …

The Use Of Chemical Element Fingerprints To Investigate The Transformation Of Lake Sediments To Land Soils In Drying Lakes: A Case Study At Lake Mead, Nevada, Ji Hye Park

UNLV Theses, Dissertations, Professional Papers, and Capstones

Drying lakes are a worldwide catastrophe. The goals of this dissertation research were (1) to investigate whether chemical fingerprints of lake sediments, and nearby land soils, could be established by the analysis of 44 chemical elements, moisture content, Eh, pH, and leachable anions and if so, (2) whether the fingerprints could help explain the process of physical and chemical changes in the lake sediments as they became soils when the lake's water level fell and the anoxic sediments were exposed to the air and weather.

Lake Mead was chosen to model drying lakes because its water level has fallen over …

Studies Of Inner-Shell Chemistry Of Mercury Based Compounds At Extreme Conditions, Sarah Schyck

UNLV Theses, Dissertations, Professional Papers, and Capstones

It has been theoretically predicted that when mercury difluoride (HgF2) is pressurized to above 50 GPa in the presence of molecular fluorine, it will most likely transform into mercury tetrafluoride (HgF4), thus mercury will behave as a transition element at high pressure. However, there is no experimental evidence verifying this prediction yet. To begin with, the crystalline properties of pure HgF2 at high pressure were not experimentally established. In this thesis, the high pressure structural properties of HgF2 are investigated by means of synchrotron X-ray powder diffraction. Our results reveal that the predicted, ambient cubic structure of HgF2 with the …
