Beyond The Screen: Uneven Geographies, Digital Labour, And The City Of Cognitive-Cultural Capitalism, Dillon Mahmoudi, Anthony M. Levenda

Urban Studies and Planning Faculty Publications and Presentations

In this paper, we demonstrate that an examination of the socio-environmental impacts of digital ICTs remains a fruitless enterprise without “materializing” digital labour. We suggest one approach to materializing digital labour: this first includes connecting political economic analyses of digital ICTs to the co-evolution and geography of planetary urbanization and technological change, and second, examining the relationships between immaterial, digital, labour with the material industrial production system. In the context of broad changes in technology, social life, and urbanization, many scholars have theorized a shift towards a third phase of capitalism, beyond mercantilism and industrialism, based in immaterial, digital, and …

Expressive Cartography, Boundary Objects, And The Aesthetics Of Public Visualization, Patricio Davila, Dave Colangelo, Robert Tu

School of Film Faculty Publications and Presentations

Aesthetic visualization projects that incorporate users, community stakeholders, multiple modalities and technologies necessarily emphasize the way that an artistic visualization can be both an artifact and a process — a conceptualization of aesthetic visualization that is useful for thinking about visualization in general. In this paper, the authors propose the concept of the visualization as boundary object, a move away from the indexical claims of visualization and instead towards an acknowledgement of the entangled nature of social, political, economic, cultural, technological and environmental actants. Through a description of the In The Air, Tonight public visualization project, the authors suggest that …

"A Bastard Jargon”: Language Politics And Identity In The Brief Wondrous Life Of Oscar Wao, Rachel Norman

Faculty Publications

This essay explores Junot Díaz's only full-length novel, The Brief Wondrous Life of Oscar Wao, through the theoretical lens of sociolinguistics and examines the ways in which Díaz has attempted to overcome the publishing industry's complicity in maintaining the nation's ethnocentric expectations in regards to English as the only acceptable language of publication. By introducing the work of several sociolinguists into the discussion, examining the use of African American Vernacular and “nerdish” alongside the Spanish, and reviewing Díaz’s relationship with his editors, I provide a more nuanced reading of the ubiquitous code-switching throughout Oscar Wao and suggest that beyond …

Assessment Of Tmdl Implementation And Water Quality Status And Trends In Amazon Creek And Coyote Creek Watersheds, Stosh Zydek

Environmental Science and Management Professional Master's Project Reports

In this project, I analyzed the status and trends of water quality data describing fecal bacteria (E. coli) and DO in the Amazon and Coyote Creek watersheds of the Southern Willamette Valley, Oregon. I also examined TMDL implementation plans produced by DMAs, determined if and how implementation activities corresponded to changes in water quality, compared management and planning of DMAs in the watersheds, discussed aspects of the current TMDL, and compared state regulations and standards in other states. I concluded by making management recommendations to better facilitate future status and trend analysis.

This urban stream contains a large wetland with an adjacent butte, all managed by the City of Gresham. This management plan addresses the preferred habitat and population of turtles at the site. A habitat delineation of the site revealed specific locations where habitat improvements could take place as well as areas of already beneficial habitat. Two site plans were prepared showing areas of the site that could be enhanced with nesting habitat as well as additional aquatic habitat and basking habitat. A habitat study …

Full State Revivals In Linearly Coupled Chains With Commensurate Eigenspectra, J. J. P. Veerman, Jovan Petrovic

Mathematics and Statistics Faculty Publications and Presentations

Coherent state transfer is an important requirement in the construction of quantum computer hardware. The state transfer can be realized by linear next-neighbour-coupled finite chains. Starting from the commensurability of chain eigenvalues as the general condition of periodic dynamics, we find chains that support full periodic state revivals. For short chains, exact solutions are found analytically by solving the inverse eigenvalue problem to obtain the coupling coefficients between chain elements. We apply the solutions to design optical waveguide arrays and perform numerical simulations of light propagation thorough realistic waveguide structures. Applications of the presented method to the realization of a …

Signal Velocity In Oscillator Arrays, Carlos E. Cantos, David K. Hammond, J. J. P. Veerman

Mathematics and Statistics Faculty Publications and Presentations

We investigate a system of coupled oscillators on the circle, which arises from a simple model for behavior of large numbers of autonomous vehicles. The model considers asymmetric, linear, decentralized dynamics, where the acceleration of each vehicle depends on the relative positions and velocities between itself and a set of local neighbors. We first derive necessary and sufficient conditions for asymptotic stability, then derive expressions for the phase velocity of propagation of disturbances in velocity through this system. We show that the high frequencies exhibit damping, which implies existence of well-defined signal velocities c+>0 and c−f(x−c+t) in the direction …

A Multivariate Nonlinear Mixed Effects Model For Longitudinal Image Analysis: Application To Amyloid Imaging, Murat Bilgel, Jerry L. Prince, Dean F. Wong, Susan M. Resnick, Bruno M. Jedynak

Mathematics and Statistics Faculty Publications and Presentations

It is important to characterize the temporal trajectories of disease-related biomarkers in order to monitor progression and identify potential points of intervention. These are especially important for neurodegenerative diseases, as therapeutic intervention is most likely to be effective in the preclinical disease stages prior to significant neuronal damage. Neuroimaging allows for the measurement of structural, functional, and metabolic integrity of the brain at the level of voxels, whose volumes are on the order of mm³. These voxelwise measurements provide a rich collection of disease indicators. Longitudinal neuroimaging studies enable the analysis of changes in these voxelwise measures. However, …

Service-Learning And The Hungry And Homeless: Tangible Sensibilities Of Care Among Young Urban Adolescents, Dilafruz R. Williams

Educational Leadership and Policy Faculty Publications and Presentations

For over 20 years, Sunnyside Environmental School in Portland, Oregon has adopted service-learning as an instructional approach to engage young people with local communities. This report explores the voices of sixth through eighth graders illustrated by their Reflection Journals as they interacted with hungry and homeless individuals in the community. The human-scale connections resulted in tangible sensibilities of care evident in students’ reflections: dispelling stereotypes as students became open-minded, making a noticeable difference however small, developing compassion through new understandings, and taking action to correct social injustices in the communities where they live.

Influence Of Silicon On The Development Of Anthracnose Of Grain Sorghum, Sanjay Pokhrel

LSU Master's Theses

To study the effect of Silicon (Si) with and without a fungicide on anthracnose development of sorghum, several experiments were conducted in the greenhouse and field. In the initial study, different Si rates [0 (control), 0 (lime control), 200, 400, 600, 800 kg Si/ha] were used in a low-Si Alfisol to determine if inoculum densities were affected by Si levels. No differences were observed between inoculum densities of 1*105 and 1*106 conidia/ml in affecting anthracnose development in the greenhouse. Anthracnose severity was found to be lowest in plants treated with 800 kg Si/ha, regardless of inoculum density. In another study, …

Touro College of Osteopathic Medicine (Middletown) Publications and Research

Sepsis is one of the leading causes of death in the United States. In order to decrease the morbidity and mortality associated with sepsis in patients, early detection is vital, and so screening protocols have been developed. The Surviving Sepsis Campaign has developed an evidence based screening guideline that has been adapted by various institutions. Having specific criteria in detecting a septic patient is the defining factor in screening for sepsis by nursing staff. In order for the sepsis protocol to be effective, it is necessary that nursing and other front line staff be educated. Institutional barriers regarding implementation of …

Vitrification Of Immature And Mature Bovine Oocytes, Paige T. Hardin

LSU Master's Theses

Vitrification is the latest technique used in cryopreservation, the ability to utilize this method with oocytes and embryos has become a valuable system. Vitrification has been successful with bovine embryos and oocytes but is far from optimal. Following cryopreservation storage discarding embryos can cause ethical issues, and mature oocytes have fragile organelles that can be detrimentally affected by ice crystal formation during freezing. Immature oocytes have not formed some of these temperature sensitive microfilaments and can circumvent these detrimental effects. The common intracellular cryoprotective agents are dimethyl sulfoxide, glycerol and ethylene glycol. Different combination of these agents have been reported …

Climate extremes are meteorological events that can have significant impacts on human and natural systems. Weather hazards, such as heat waves, drought, heavy thunderstorms, floods, hurricanes, occur frequently, and are a threat to human lives and property. Climate data observations spanning over 100 years are an important asset in understanding climate extremes and trends. This research uses daily climate data observations from more than 3000 climate stations in the continental U.S. to assess the climate trends and extremes, including temperature, precipitation, and snowfall. The climate data measurement sites were grouped by climate divisions and each climate division was statistically assessed …

Euphoria From Drinking Alcoholic Beverages May Be Due To Reversible Constriction Of Cerebral Blood Vessels: Potential Roles Of Unrecognized Ionized Hypomagnesemia, And Release Of Ceramides And Platelet-Activating Factor, Burton M. Altura, Aimin Zhang, Nilank C. Shah, Gatha J. Shah, Asefa Gebrewold, Bella T. Altura

Touro College of Osteopathic Medicine (Middletown) Publications and Research

The authors discuss the feeling of euphoria when drinking alcohol. They summarize studies that suggest this feeling is due to blood vessel constriction, and explain why they believe that the specific mechanism that results in euphoria is the rapid, reversible release o free magnesium ions ([Mg2+]) coupled to the release of ceramides and platelet-activating factor (PAF).

Resonant Inductive Coupling As A Potential Means For Wireless Power Transfer To Printed Spiral Coil, Mohammad Haerinia, Ebrahim S. Afjei

Electrical Engineering Student Publications

This paper proposes an inductive coupled wireless power transfer system that analyses the relationship between induced voltage and distance of resonating inductance in a printed circuit spiral coils. The resonant frequency produced by the circuit model of the proposed receiving and transmitting coils are analysed by simulation and laboratory experiment. The outcome of the two results are compared to verify the validity of the proposed inductive coupling system. Experimental measurements are consistent with simulations over a range of frequencies spanning the resonance.

Improvisational Unionism, Michael M. Oswalt

Faculty Articles, Papers, and Other Scholarship

Recent fights for a $15-an-hour minimum wage at Walmart and in the fast-food industry have interested academics, captivated the press, and energized the public. For good reason. The campaigns upend conventional wisdom about what unions do (help workers win collective bargaining rights) and why they do it (build the membership). Scattered flash strikes for seemingly impossible or idiosyncratic goals on no obvious timeline have shattered that mold. Though much has already been said about these developments, scholarship has yet to provide a rigorous theoretical frame to categorize and explain the new form of activism. This Article argues that improvisation — …

Limiting Deterrence: Judicial Resistance To Detention Of Asylum-Seekers In Israel And The United States, Michael Kagan

Scholarly Works

Governments have advanced the argument that asylum-seekers may be detained in order to deter other would-­be asylum­-seekers from coming. But in recent litigation in the United States and Israel, this justification for mass detention met with significant resistance from courts. This Essay looks at the way the American and Israeli courts dealt with the proposed deterrence rationale for asylum-seeker detention. It suggests that general deterrence raises three sequential questions:

1. Is deterrence ever legitimate as a stand alone justification for depriving people of liberty?

2. If deterrence is sometimes legitimate, is it valid as a general matter in migration control, …
