Surviving The Anthropocene Through The Arts, Virgilio Rivas, Jeffrey Bartilet, Jayson Jimenez Dec 2015

Surviving The Anthropocene Through The Arts, Virgilio Rivas, Jeffrey Bartilet, Jayson Jimenez

Mabini Review

We are in the age of disasters, an era of climate change, of extreme and life-threatening weather disturbances, of flash floods and super-typhoons. But we are also in an age of voracious consumption of resources, an era of massive oil and nuclear energy use, an age of wastelands and carbon emissions, an age of steel, of plastic, and concrete, the age of GMOs, of soil alteration and water depletion. This is the age of what recent scholars call the Anthropocene, the era of how the human being becomes a geological agent changing the planet. This is where the project hopes …


The City As A Spectacular Monster And The Hysterical Baudrillardian Flâneur, Gian Carla Agbisit Dec 2015

The City As A Spectacular Monster And The Hysterical Baudrillardian Flâneur, Gian Carla Agbisit

Mabini Review

Propelled by the new kind of capitalism, and aided by a scientific and technological progress that culminates in virtual perfection, the city has now become both the producer and the consumer of spectacle. Caught in a tangle of means and ends, the spectacle that used to be merely an icing of the cake, a tiny ribbon of the dress, a glitter, or a slight shimmer, has become the product to be consumed.

Reinforcing The Identity Of The African Children's Rights Committee: A Case For Limiting The Lust For Judicial Powers In Quasi -Judicial Human Rights Mechanisms, Solomon T. Ebobrah Dec 2015

Reinforcing The Identity Of The African Children's Rights Committee: A Case For Limiting The Lust For Judicial Powers In Quasi -Judicial Human Rights Mechanisms, Solomon T. Ebobrah

The Transnational Human Rights Review

Established as a quasi-judicial treaty supervisory body rather than an international court, the African Committee of Experts on the Rights and Welfare of the Child struggles for relevance in the African human rights system where most non-state stakeholders arguably prefer organs with clear judicial powers. Thus, similar to the experiences of its older counterparts, the Committee appears to be under subtle pressure to substitute or at least reinforce its quasi-judicial character with more judicial powers and action. In essence, the Committee suffers from the uncertainty that prevails in international law regarding the definition of the term quasi-judicial; and the unclear …


The Bullies On The Block: What's Killing Secondhand Bookstores?, Kristen Stedman Dec 2015

The Bullies On The Block: What's Killing Secondhand Bookstores?, Kristen Stedman

Faculty Curated Undergraduate Works

Reading is idolized in our society. Being a book-lover is a trait that many, including myself, share. Yet, all over the world, independent bookstores are dying due to the rise of Amazon, the pressure of gentrification, and the prevalence of supermarket bookstores. Independent bookstores are of immense cultural significance to us as close-knit, welcoming communities of concentrated creativity, emphasizing the need to be concerned over their diminishing numbers. The factors causing their plight are researched through scholarly sources and then further explored through variety of interviews- with the shop owner, with people who choose to frequent independent bookstores, and with …


Ocean Acidification As One Of Multiple Stressors: Growth Response Of Thalassiosira Weissflogii (Diatom) Under Temperature And Light Stress, Uta Passow, Edward A. Laws Dec 2015

Ocean Acidification As One Of Multiple Stressors: Growth Response Of Thalassiosira Weissflogii (Diatom) Under Temperature And Light Stress, Uta Passow, Edward A. Laws

Faculty Publications

Future shifts in phytoplankton composition and productivity are anticipated given that continuing changes are expected in environmental conditions such as temperature, the partial pressure of CO2 (pCO2) and light climate, all of which regulate phytoplankton communities and their physiology through bottom-up control. Culture experiments revealed that future (elevated) pCO2 had no effect on Thalassiosira weissflogii in the absence of environmental stressors, whereas growth rates drastically decreased under future pCO2 when cells were grown under light and temperature stress. Reduction in growth rates and a smaller decline in cellular photosynthesis under high pCO2 were associated with 2- to 3-fold increases in …


Cbt Group Intervention To Increase Cpap Adherence Among Veterans With Sleep Apnea: A Pilot Investigation, Katie Patricia Lang Dec 2015

Cbt Group Intervention To Increase Cpap Adherence Among Veterans With Sleep Apnea: A Pilot Investigation, Katie Patricia Lang

Electronic Theses and Dissertations Archive

Sleep Apnea (SA) is gaining increased attention among military populations due to the increasing prevalence rates (40-60%) and risk of serious health complications (i.e., cognitive decline, stroke) when untreated. Unfortunately, adherence to Continuous Positive Airway Pressure (CPAP; the gold standard treatment) is chronically low. This study examined the efficacy of a 6-week CBT group intervention to increase CPAP adherence among veterans diagnosed with SA and prescribed CPAP treatment. A final sample of 35 veterans was randomly assigned either to treatment as usual (TAU) or TAU plus the CBT group intervention. Participants completed various self-report measures and a therapist-administered cognitive screening …


The Social Value Of Academic Freedom Defended, J. Peter Byrne Dec 2015

The Social Value Of Academic Freedom Defended, J. Peter Byrne

Indiana Law Journal

In his recent book, Versions of Academic Freedom: From Professionalism to Revolution, Stanley Fish renewed his arguments for an “it’s just a job” account of academic freedom, begun in his 2008 book, Save the World on Your Own Time. He claims that academic freedom consists of nothing more than the conditions necessary to follow the established criteria for scholarship and teaching within each discipline. He complains chiefly against the invocation of academic freedom to protect or glorify political advocacy by academics. There is a lot in Fish’s account to admire and agree with. The appropriate sphere of academic freedom needs …


The Regrettable Underenforcement Of Incompetence As Cause To Dismiss Tenured Faculty, David M. Rabban Dec 2015

The Regrettable Underenforcement Of Incompetence As Cause To Dismiss Tenured Faculty, David M. Rabban

Indiana Law Journal

Universities are extremely reluctant to dismiss tenured professors for incompetence. This reluctance compromises the convincing and broadly accepted justification for the protection of academic freedom through tenure set forth in the 1915 Declaration of Principles of the American Association of University Professors (AAUP). After asserting that society benefits from the academic freedom of professors to express their professional views without fear of dismissal, the 1915 Declaration maintained that the grant of permanent tenure following a probationary period of employment protects academic freedom. Yet the 1915 Declaration also stressed that academic freedom does not extend to expression that fails to meet …


A Preliminary Assessment Of Water Partitioning And Ecohydrological Coupling In Northern Headwaters Using Stable Isotopes And Conceptual Runoff Models, James P. Mcnamara Dec 2015

A Preliminary Assessment Of Water Partitioning And Ecohydrological Coupling In Northern Headwaters Using Stable Isotopes And Conceptual Runoff Models, James P. Mcnamara

Geosciences Faculty Publications and Presentations

We combined a conceptual rainfall-runoff model and input–output relationships of stable isotopes to understand ecohydrological influences on hydrological partitioning in snow-influenced northern catchments. Six sites in Sweden (Krycklan), Canada (Wolf Creek; Baker Creek; Dorset), Scotland (Girnock) and the USA (Dry Creek) span moisture and energy gradients found at high latitudes. A meta-analysis was carried out using the Hydrologiska Byråns Vattenbalansavdelning (HBV) model to estimate the main storage changes characterizing annual water balances. Annual snowpack storage importance was ranked as Wolf Creek > Krycklan > Dorset > Baker Creek > Dry Creek > Girnock. The subsequent rate and longevity of melt were reflected in calibrated parameters …


Pushing Past The Plateau: A Diary Study Of A Not Quite Intermediate Korean Language Learner, Jonathan D. Wilson Dec 2015

Pushing Past The Plateau: A Diary Study Of A Not Quite Intermediate Korean Language Learner, Jonathan D. Wilson

School of Education and Leadership Student Capstone Theses and Dissertations

In this study the author explores the internal and personal aspects of his own learning of the Korean language through the qualitative perspective of a language learning diary. Language fossilization is brought into focus as the author resumes learning the language after a three year break and attempts to push past his perceived plateau. Fossilization is a foundational concept in the field of adult Second Language Acquisition (SLA), yet seemingly none have covered this issue using the diary study design and the unique, inside perspective that this design offers. The author developed his own study plan and recorded regular introspective …

Multi-Criteria Evaluation Of Cmip5 Gcms For Climate Change Impact Analysis, Ali Ahmadalipour, Arun Rana, Hamid Moradkhani, Ashish Sharma

Civil and Environmental Engineering Faculty Publications and Presentations

Climate change is expected to have severe impacts on global hydrological cycle along with food-water-energy nexus. Currently, there are many climate models used in predicting important climatic variables. Though there have been advances in the field, there are still many problems to be resolved related to reliability, uncertainty, and computing needs, among many others. In the present work, we have analyzed performance of 20 different global climate models (GCMs) from Climate Model Intercomparison Project Phase 5 (CMIP5) dataset over the Columbia River Basin (CRB) in the Pacific Northwest USA. We demonstrate a statistical multicriteria approach, using univariate and multivariate techniques, …

From JEff=1/2 Insulator To P-Wave Superconductor In Single-Crystal Sr2Ir1−XRuXO4 (0≤X≤1), Shujuan Yuan, Saicharan Aswartham, Jsaminka Terzic, H. Zheng, H. D. Zhao, P. Schlottmann, Gang Cao Dec 2015

From JEff=1/2 Insulator To P-Wave Superconductor In Single-Crystal Sr2Ir1−XRuXO4 (0≤X≤1), Shujuan Yuan, Saicharan Aswartham, Jsaminka Terzic, H. Zheng, H. D. Zhao, P. Schlottmann, Gang Cao

Physics and Astronomy Faculty Publications

Sr2IrO4 is a magnetic insulator assisted by strong spin-orbit coupling (SOC) whereas Sr2RuO4 is a p-wave superconductor. The contrasting ground states have been shown to result from the critical role of the strong SOC in the iridate. Our investigation of structural, transport, and magnetic properties reveals that substituting 4dRu4+(4d4) ions for 5dIr4+(5d5) ions in Sr2IrO4 directly adds holes to the t2g bands, reduces the SOC, and thus rebalances the competing energies in single-crystal Sr …


Supermassive Black Hole Seed Formation At High Redshifts: Long-Term Evolution Of The Direct Collapse, Isaac Shlosman, Jun-Hwan Choi, Mitchell C. Begelman, Kentaro Nagamine Dec 2015

Supermassive Black Hole Seed Formation At High Redshifts: Long-Term Evolution Of The Direct Collapse, Isaac Shlosman, Jun-Hwan Choi, Mitchell C. Begelman, Kentaro Nagamine

Physics and Astronomy Faculty Publications

We use cosmological adaptive mesh refinement code enzo zoom-in simulations to study the long-term evolution of the collapsing gas within dark matter haloes at z. This direct collapse process is a leading candidate for rapid formation of supermassive black hole (SMBH) seeds. To circumvent the Courant condition at small radii, we apply the sink particle method, focusing on evolution on scales ∼0.01–10 pc. The collapse proceeds in two stages, with the secondary runaway happening within the central 10 pc. The sink particles form when the collapsing gas requires additional refinement of the grid size at the highest refinement level. …


Ergonomic Analysis Of Mobile Cart–Assisted Stocking Activities Using Electromyography, Sohyung Cho Dec 2015

Ergonomic Analysis Of Mobile Cart–Assisted Stocking Activities Using Electromyography, Sohyung Cho

SIUE Faculty Research, Scholarship, and Creative Activity

Workers in grocery stores are exposed to numerous musculoskeletal risks that can be reduced using assistive devices while performing stocking tasks. A regional grocery store has recently deployed a mobile cart without comprehension of its ergonomic impact on workers, which this article investigates using normalized electromyography data (%MVC). This article studies not only ergonomic impact based on %MVC values but also work performance represented by a muscle force metric (MFM). The results from this study showed highest muscle groups in %MVC and MFM were the erector spinae and triceps. Interestingly, muscle activations on erector spinae were reduced when mobile cart …

Indigenous Women, Water Justice And Zaagidowin (Love), Deborah Mcgregor

Articles & Book Chapters

I would like to open by saying Chi-miigwech (a big thank-you) to those Elders/Grandmothers who have shared their stories and teachings with me over the years. Some have since passed on and I hope that through my words, their love and generosity will continue the process of healing the people and waters upon which they so integrally depend.

The paper which follows contains many references to notions of love, mutual respect, and responsibility towards the natural world, and water in particular. These ideas may seem a little tenuous for a serious paper on a critical environmental justice issue, but concepts …


Mineralogy And Geochemistry Of Late Archean And Paleoproterozoic Granites And Pegmatites In The Northern Penokean Terrane Of Marquette And Dickinson Counties, Michigan, Christopher M. Johnson, Christopher M. Van Daalen Dec 2015

Mineralogy And Geochemistry Of Late Archean And Paleoproterozoic Granites And Pegmatites In The Northern Penokean Terrane Of Marquette And Dickinson Counties, Michigan, Christopher M. Johnson, Christopher M. Van Daalen

LSU New Orleans Theses and Dissertations

This thesis focuses on mineralogy, geochemistry, and origin of eight pegmatites and two spatially associated granites of Late Archean and Paleoproterozoic ages located in Marquette and Dickinson Counties, Michigan. Biotite geochemistry reveals that both granites and all pegmatites are peraluminous and have an orogenic signature. However, bulk composition reveals the Humboldt granite is a peraluminous A-type granite and the Bell Creek granite is a peraluminous mix between I-, S-, and A-type granites. The Republic Mine pegmatite appears to be geochemically similar to the Bell Creek granite and Grizzly pegmatite. The Crockley pegmatite is genetically related to the Humboldt granite. The …


Characteristics Of Boundary Layer Flow Induced By Solitary Wave Propagating Over Horizontal Bottom, Chang Lin, Shi-Min Yu, Po-Hung Yeh, Min-Hsuan Yu, Ching-Piao Tsai, Shih-Chun Hsieh, Ming-Jer Kao, Guang-Wei Tzeng, Rajkumar Raikar Dec 2015

Characteristics Of Boundary Layer Flow Induced By Solitary Wave Propagating Over Horizontal Bottom, Chang Lin, Shi-Min Yu, Po-Hung Yeh, Min-Hsuan Yu, Ching-Piao Tsai, Shih-Chun Hsieh, Ming-Jer Kao, Guang-Wei Tzeng, Rajkumar Raikar

Journal of Marine Science and Technology–Taiwan

Experimental results on the flow characteristics of bottom boundary layer induced by a solitary wave propagating over a horizontal bottom are presented. Particle-trajectory flow visualization technique and high-speed particle image velocimetry (HSPIV) were used to elucidate detailed velocity fields underneath solitary waves with the ratios of wave height to water depth from 0.130 to 0.386. The results show that the velocity profiles can be classified into two classes with respect to the passage of the solitary wave-crest at the measuring section: the pre-passing and post-passing phases. For the pre-passing phase, the velocity distributions can be deduced to a unique similarity …


Foreign Account Tax Compliance Act: The Most Revolutionary Piece Of Tax Legislation Since The Introduction Of The Income Tax, Alexander Szwakob Dec 2015

Foreign Account Tax Compliance Act: The Most Revolutionary Piece Of Tax Legislation Since The Introduction Of The Income Tax, Alexander Szwakob

Honors Scholar Theses

With taxation of income being the most significant source of revenue, most national governments consider tax evasion prevention to be one of the priorities of their tax agencies. In the United States, tax evasion has been a significant concern of the Internal Revenue Service ever since the modern income tax was instituted with the passing of the Sixteenth Amendment in 1913. Over the following century, Congress enacted numerous measures aimed at curbing the illegal practice, but, as often is the case, both individuals and institutions desiring to not abide by the law found new ways to outsmart the tax authorities. …


Wildland Fire Deficit And Surplus In The Western United States, 1984-2012, Sean A. Parks, Carol Miller, Marc-Andrè Parisien, Lisa M. Holsinger, Solomon Z. Dobrowski, John Abatzoglou Dec 2015

Wildland Fire Deficit And Surplus In The Western United States, 1984-2012, Sean A. Parks, Carol Miller, Marc-Andrè Parisien, Lisa M. Holsinger, Solomon Z. Dobrowski, John Abatzoglou

Forest Management Faculty Publications

Wildland fire is an important disturbance agent in the western US and globally. However, the natural role of fire has been disrupted in many regions due to the influence of human activities, which have the potential to either exclude or promote fire, resulting in a "fire deficit" or "fire surplus," respectively. In this study, we developed a model of expected area burned for the western US as a function of climate from 1984 to 2012. We then quantified departures from expected area burned to identify geographic regions with fire deficit or surplus. We developed our model of area burned as …

Focus group participants gave feedback on …


Brewing Identity: The Tavern’S Imprint On The American Revolution, Cailin Edgar Dec 2015

Brewing Identity: The Tavern’S Imprint On The American Revolution, Cailin Edgar

History & Classics Undergraduate Theses

This thesis examines the role of the tavern in late eighteenth-century America and the many ways in which they helped support, sustain, and determine the outcome of the movement toward Independence. Taking the argument one step further, the paper focuses on the intersection of tavern culture and print materials to underscore the multidimensionality of this public discursive space as a platform for print to come to life, exposing a more wide-reaching population of the colonists to the same material, and thus cultivating in the process a common intellectual experience between otherwise-detached New World neighbors. This study is located primarily in …


Mons Maiorum: Roman Aristocracy And The Palatine Hill's Appropriated Memory, Charles T. Rainville Iii Dec 2015

Mons Maiorum: Roman Aristocracy And The Palatine Hill's Appropriated Memory, Charles T. Rainville Iii

History & Classics Undergraduate Theses

Mons Maiorum arguest against the all-to-common a line of thinking among some scholars of ancient Rome: that house exchange of “ancient families surviving in genetic and property continuity [is] not characteristic of Rome.” This belief relies fundamentally on evidence from Roman authors after the proscriptions of the first century BC, when long-established aristocratic families had been removed from the landscape of the Palatine, and Roman memory. It is thus short sighted not to consider the depth of myths, physical monuments, and Roman customs as evidence for a close association of generations of Romans living in family property with a special …

Human Immunodeficiency Virus Type 1 Envelope Protein Interaction With Host Cell Coreceptor C-X-C Chemokine Receptor Type 4, Jie Zhang Dec 2015

Human Immunodeficiency Virus Type 1 Envelope Protein Interaction With Host Cell Coreceptor C-X-C Chemokine Receptor Type 4, Jie Zhang

Arts & Sciences Graduate Student Theses and Dissertations

Human Immunodeficiency Virus Type 1 (HIV-1) envelope protein is the sole determinant for viral entry and tropism. The ability of HIV-1 to infect susceptible host cells depends on the ability of its envelope protein to engage host cell receptor CD4 and coreceptor C-C Chemokine Receptor Type 5 (CCR5) and/or C-X-C Chemokine Receptor Type 4 (CXCR4). Most naturally occurring infections start with a single CCR5-tropic virion. In approximately 50% of HIV-1 Clade B infected patients, the viral population spontaneous develops the ability to utilize CXCR4 at a late disease stage, and this coreceptor shift corresponds to a poor prognosis for the …


Identifying The Origin Of Galactic Cosmic Rays With The Supertiger Instrument, Ryan Patrick Murphy Dec 2015

Identifying The Origin Of Galactic Cosmic Rays With The Supertiger Instrument, Ryan Patrick Murphy

Arts & Sciences Graduate Student Theses and Dissertations

The SuperTIGER (Trans-Iron Galactic Element Recorder) experiment was launched on a long-duration balloon flight from Williams Field, Antarctica, on December 8, 2012. The instrument measured the relative elemental abundances of galactic cosmic rays (GCR) in the charge (Z) range Z>10 with excellent charge resolution, displaying well resolved individual element peaks for 10 ≤ Z ≤ 40. During its record-breaking 55-day flight, SuperTIGER collected ~4.15 x10^6 Iron nuclei, ~ 7.5 times as many as detected by its predecessor, TIGER, with charge resolution at iron of < 0.18 cu. SuperTIGER measures charge (Z) and energy (E) using a combination of three scintillator and two Cherenkov detectors, and employs a scintillating fiber hodoscope for event trajectory determination. The SuperTIGER data have been analyzed to correct for instrument effects and remove events that underwent nuclear interactions within the instrument. The data include more than 600 events in the charge range 30 < Z ≤ 40. SuperTIGER is the first experiment to resolve elemental abundances in this charge range with single-element resolution and high statistics. The relative abundances of the galactic cosmic ray source have been derived using atmospheric and interstellar propagations of the measured relative elemental abundances. The SuperTIGER measured abundances are generally consistent with previous experimental results from TIGER and ACE-CRIS, with improved statistical precision. The SuperTIGER results confirm the earlier results from TIGER, supporting a model of cosmic-ray origin in OB associations, with preferential acceleration of refractory elements over volatile elements ordered by atomic mass (A).

West Antarctica consists of several tectonically diverse terranes, including the West Antarctic Rift System, a topographic low region of extended continental crust. In contrast, the adjacent Marie Byrd Land and Ellsworth-Whitmore mountains crustal blocks are on average over 1km higher, with the former dominated by polygenetic shield and stratovolcanoes protruding through the West Antarctic ice sheet and the latter having a Precambrian basement. The upper mantle structure of these regions is important for inferring the geologic history and tectonic processes, as well as the influence of the solid earth on ice sheet dynamics. Yet this structure is poorly constrained due …
