Hito Steyerl's "Duty-Free Art" As Politics And Pedagogy, Rachel Carina Sigismondi

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

How does contemporary art engage the contemporary, exactly? Artist Hito Steyerl actively engages this question in her recent works. One might notice upon visiting a Hito Steyerl exhibition that her video works often include recordings of lectures she has given to live audiences in art spaces. Because Steyerl is engaged in this pedagogical practice as an artist, can it be considered contemporary art? Steyerl’s written, lectured, and visual works engage the contemporary moment prodigiously, and cannot be eschewed in an analysis of the perpetually evolving nature of contemporary art. With the use of critical, theoretical and formal analytical tools, this …

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Hardly any political scientist would disagree that partisanship is a key variable in political behavior research: It predicts vote choice, political attitudes and core values as well as party leader evaluations and political activism. We observe these effects especially among strong partisans – a segment of the American electorate that has notably increased in recent years. While the consequences of strong partisanship for political behavior are well-known, we still lack a theoretical framework as well as corresponding empirical evidence that explains why some partisans are deeply attached to their party whereas others lack that type of strong commitment. I address …

The Impact Of Campaign Finance On Roll Call Behavior, Voter Perceptions, And Democratic Responsiveness, David Stack Dec 2016

The Impact Of Campaign Finance On Roll Call Behavior, Voter Perceptions, And Democratic Responsiveness, David Stack

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Levels of partisanship and polarization within Congress are at high levels. However, this development defies the expectation of Downsian models. My dissertation attributes polarization to the activity of political donors. Using a database of over 13.5 million individual donors, I use advanced time series models to show that donors have been increasingly rewarding Republicans who toe the party line. In the second section of my dissertation, I explore how incumbent politicians may be using these campaign contributions to offset any potential electoral penalties for excessive partisanship. My examination of survey evidence shows that incumbents may be using campaign spending to …

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Powder coatings are becoming ubiquitous in the coating marketplace due to the absence of solvents in their formulation, but they have yet to see implementation in low-reflectance outdoor applications. This demand could be met by utilizing polymer blends formulated with low loadings of matting agents and pigments. The goal of this research is a thorough characterization of prototype low-reflectance coatings through several analytical techniques. Prototypical thermoset blends consist of functionalized polyurethanes rendered immiscible by differences in polar and hydrogen bonding characteristics, resulting in a surface roughened by droplet domains. Analysis of both pigmented and control clear films was performed. This …

Interrogation Of Possible Imaging Conditions For Radiation Sensitive Metal Organic Frameworks In Transmission Electron Microscopes, Wei-Yu Pan

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Although transmission electron microscopy (TEM) is extremely powerful at the characterization of materials on the nano- and atomic scales, the advantages introduce accompanying drawbacks. That is, high energy electrons offer the structural information while imparting radiation damage to the samples. Metal organic frameworks are a new class of materials that have potential applications in gas storage and catalysis. A direct imaging of their lattice structures is highly desired. However, these samples are extremely radiation sensitive. In order to characterize their structures, low-dose TEM need to be performed. To date, there is a lack of a systematic of radiation study of …

Dilation Behavior Of Thermal Spray Coatings, Miryan Lorena Bejarano

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Thermal Spray (TS) is a very versatile manufacturing process to deposit thick coatings on a variety of substrates. Coatings are used in protective (i.e. wear, chemical attack, high temperature, etc.) and functional (i.e. sensors) applications. TS coatings have a unique lamellar microstructure as a result of the overlapping of millions of molten and partially-molten particles. During processing, high deformation by impact, high temperature, and rapid solidification lead to a complex hierarchical material system that contains a high amount of microstructural defects. The presence of defects in the microstructure contribute to differences in property values in comparison to bulk materials. Thermal …

G-Alpha-Q Regulation On Cardiac Autophagy, Shengnan Liu Dec 2016

G-Alpha-Q Regulation On Cardiac Autophagy, Shengnan Liu

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Receptors that activate the heterotrimeric G protein Gαq are thought to play a role in the development of heart failure. Dysregulation of autophagy occurs in some pathological cardiac conditions including heart failure, but whether Gαq is involved in this process is unknown. A cardiomyocyte-specific transgenic mouse model of inducible Gαq activation (termed GαqQ209L) was used to address this question. Autophagy is a quality control and recycling process in which double-membrane vesicles called autophagosomes enclose intracellular materials and send them to lysosomes for degradation. After 7 days of Gαq activation, GαqQ209L hearts contained more autophagic vacuoles than wild type (WT) hearts. …

Synaptonemal Complex Disassembly Activates Rad51-Mediated Double Strand Break Repair During Budding Yeast Meiosis, Evelyn Joann Prugar Dec 2016

Synaptonemal Complex Disassembly Activates Rad51-Mediated Double Strand Break Repair During Budding Yeast Meiosis, Evelyn Joann Prugar

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Meiosis is a highly conserved specialized cell division that occurs in many organisms, including budding yeast and mammals. Meiosis divides the chromosome number of the cell in half to create gametes for sexual reproduction. A single round of chromosome duplication is followed by two rounds of chromosome segregation, Meiosis I (homologs segregate) and Meiosis II (sister chromatids segregate). Proper segregation at Meiosis I requires that homologs are connected by both crossovers and sister chromatid cohesion. Crossovers are formed by the repair of double strand breaks (DSBs) preferentially by the homolog. The choice of repair template is determined at the time …

Bet Inhibition Releases The Mediator Complex From Specific Cis Elements In Acute Myeloid Leukemia Cells, Anand Shripad Bhagwat

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Acute myeloid leukemia (AML) is a hematologic malignancy with a 5-year survival rate of less than 30%. We recently identified the bromodomain and extraterminal (BET) protein Brd4 as a therapeutic target in AML, and several trials are currently evaluating the clinical utility of BET inhibitors for this disease. BET inhibitors displace Brd4 from chromatin and subsequently reduce the expression of key oncogenes, such as Myc, leading to AML blast differentiation and cell death. However, the mechanism by which Brd4 maintains oncogene expression in AML is still unclear. We hypothesized that Brd4 functions by working with other coactivators in AML to …

Mantle Composition And Temperature Of Western North America Revealed From In-Situ Velocity Measurements Of Klb-1 Peridotite, Xuebing Wang Dec 2016

Mantle Composition And Temperature Of Western North America Revealed From In-Situ Velocity Measurements Of Klb-1 Peridotite, Xuebing Wang

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The composition and thermal structure of the Earth’s mantle, especially the mantle transition zone, still remain controversial due to the lack of direct access to the Earth’s interior. An important geophysical approach to constrain the mineralogical composition of the mantle is to compare seismic profiles (e.g. | PREM and AK135) with the elasticity of candidate compositional models calculated by averaging schemes based on the phase equilibrium and elasticity data of individual mantle minerals. However, chemical reactions, element partitioning and diffusion cannot be fully taken into account by this approach. In this study, I conducted direct velocity measurements on KLB-1 peridotite …

Wave Gradiometry And Its Link With Helmholtz Equation Solutions Applied To Usarray, Yuanyuan Liu Dec 2016

Wave Gradiometry And Its Link With Helmholtz Equation Solutions Applied To Usarray, Yuanyuan Liu

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Wave gradiometry is an array processing technique using the shape of seismic wavefields captured by dense seismic arrays to estimate fundamental wave propagation characteristics [Langston, 2007a,b; Liang and Langston, 2009]. We first explore a compatibility relation that links the spatial gradients to displacements and velocity seismograms through two unknown coefficients: A⃗ and B⃗. We show that the A⃗-coefficient corresponds to the gradient of logarithmic amplitude and the B⃗ -coefficient corresponds approximately to the local wave slowness. These coefficients are solved through iterative, damped least- squares inversions to provide estimates of four gradiometry products: dynamic phase velocity, back-azimuth, radiation pattern and …

Justices Of The Peace, Lawyers And The People: Local Courts And The Contested Professionalization Of Law In Late Colonial New York, Sung Yup Kim Dec 2016

Justices Of The Peace, Lawyers And The People: Local Courts And The Contested Professionalization Of Law In Late Colonial New York, Sung Yup Kim

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Legal professionalization in New York was a contested social process entailing myriad local struggles over the use of land and credit. New York’s legal professionalization gained momentum in the mid-eighteenth century, as provincial lawyers pursued a collective mission to monopolize doctrinal interpretation and procedural application of English common law in the colony. The on-the-ground application of that mission frequently pitted lawyers against commoners, many of whom preferred the informal resolutions provided by lay justices, jurors, arbitrators, and town meetings. Professionalized law determined cases with doctrines and procedures alien to most laypeople. It disrupted the local communities’ means of equitable dispute …

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Carbon monoxide (CO) is a trace gas that influences atmospheric chemical reactions. CO is relatively short-lived (weeks to months) in the atmosphere and therefore spatially variable with a modern concentration range from 35 parts per billion (ppb) to 150 ppb (Globalview-CO, 2009). Because of its lifetime, atmospheric carbon monoxide is a good tracer for hemispheric processes; it is long enough to be transported over hemispheric distances but is short enough where there can be large seasonal and interannual variations. Therefore, measuring the variations in CO from bubbles trapped in Antarctic ice can reveal processes that occur in the Southern Hemisphere …

Development Of The Simplified Land Model (Slm) And Its Application To The Diurnal Cycle Of Precipitation Over Land, Jungmin Lee Dec 2016

Development Of The Simplified Land Model (Slm) And Its Application To The Diurnal Cycle Of Precipitation Over Land, Jungmin Lee

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The diurnal cycle of convection is a key to understanding the climate and weather in the context of the Earth’s energy and water cycles. Yet, the well-observed late afternoon to early evening precipitation maximum over most of inland regions still remains one of the poorly understood features of continental convection. Many numerical weather and global climate models (GCMs) have had difficulty capturing the correct diurnal cycle of convection over land. Not only does this deficiency create a concern regarding the consistency of GCMs’ physical parameterizations, but it also requires a better understating of physical processes that control the land-atmosphere interactions. …
