A Toolkit For Tracking And Mediating Parametric Objects Upon Commodity Mobile Devices, Shantanu Thatte Jan 2014

A Toolkit For Tracking And Mediating Parametric Objects Upon Commodity Mobile Devices, Shantanu Thatte

LSU Master's Theses

The large number of mobile devices introduced in the market in recent years provide numerous interaction opportunities. We used commercially available products to create an interface for interaction with diverse datasets. We extended this scenario to include multiple physical instances, realizing a real-time multi-party interaction session. Tangibles act as tools and containers, in a fashion that requires their physical location and orientation to be evaluated continuously during a session. We present a technique to detect an object using only the touchscreen of a mobile device as an input, by means of touch patterns created on the screen. This helps avoid …

Effects Of Latitude On The Competitive Ability Of Native And Invasive Genotypes Of Phragmites Australis, Anthony K. Chow Jan 2014

Effects Of Latitude On The Competitive Ability Of Native And Invasive Genotypes Of Phragmites Australis, Anthony K. Chow

LSU Master's Theses

One commonly cited mechanism for the success of invasive species is their superior competitive ability relative to that of native species. Although 88% (22 of 25) of the empirical studies support the prediction that the strength of competition for native species increases with latitude, no studies to date have compared the competitive ability of native and co-occurring invasive species across a broad latitudinal range. In a greenhouse, I investigated whether the competitive ability of North American native and European invasive haplotypes of Phragmites australis vary with latitude. Another widespread, non-indigenous haplotype, the Gulf Coast haplotype, was also included for assessment …

Remittance And Migration: Impact On Technology Adoption, Natural Resource Conservation, And Household Welfare, Deborah Ann Williams Jan 2014

Remittance And Migration: Impact On Technology Adoption, Natural Resource Conservation, And Household Welfare, Deborah Ann Williams

LSU Master's Theses

Nepal is the perfect country to study all the facets of migration, sustainable agriculture and their subsequent impact on food systems. Droves of migrants are leaving rural Nepal for higher incomes to cover household daily expenses. The Government of Nepal (GON) encourages migration as a means to reduce poverty, and remittance already amounts to 25.83% of GDP, and it is expected to grow (Nepal Bastra Bank 2014, Thieme and Wyss 2005, Yang 2011). However, it is still unclear whether the mass exodus from rural areas and the growing dependence on remittance, the portion of the migrant workers' earnings sent back …

Education Ain't Black: The Disidentification Of African American Students, Erica Lynette James Jan 2014

Education Ain't Black: The Disidentification Of African American Students, Erica Lynette James

LSU Master's Theses

In this thesis, I will discuss the influence of education on the identity formation of African American students. Based on the scholarly literature in education theory, I will argue in Bourdieuan theory education, formal education, fails to accommodate the specific needs of African American students because education influences African American students to develop constructions of “whiteness" that education reinforces. As education attempts to uphold the “status quo” of American society, education simultaneously forces African American students to question the relevance of education. In questioning the relevance of education through high-achieving African American students’ use of language and pursuit of academic …

A Quantitative And Molecular Evaluation Of Calves Sired By Three Different Breeds For Growth, Performance, And Carcass Traits, Malcolm Seth Mizell Jan 2014

A Quantitative And Molecular Evaluation Of Calves Sired By Three Different Breeds For Growth, Performance, And Carcass Traits, Malcolm Seth Mizell

LSU Master's Theses

The first objective of the two studies in the research herein was to evaluate growth, performance and carcass quality and composition traits from a group of spring born calves sired by Charolais, Braunvieh, or Simmental bulls. Growth traits analyzed included birth weight (BW), weaning weight (WW), and hip height (HH). Carcass quality and composition traits analyzed included hot carcass weight (HCW), rib eye area (REA), back fat thickness (BF), marbling score (MS), and yield grade (YG). Analysis revealed Simmental sired calves were significantly heavier (P<.05) at birth when compared to Charolais and Braunvieh sired calves. Braunvieh sired calves were reported to be significantly (P<.05) shorter than Simmental sired calves for hip height. Hot carcass weight analysis revealed that Charolais sired calves were significantly (P<.05) heavier when compared to Braunvieh sired calves. No individual sire breed group displayed any significant differences for weaning weight, rib eye area, back fat thickness, marbling score, or yield grade. The second objective was evaluate potential SNP associations on four candidate genes with growth, performance, and carcass composition traits in a population of crossbred steers sired by Charolais, Braunvieh, and Simmental bulls. Traits analyzed for growth, performance, and carcass traits were previously mentioned. Analysis was performed on 38 steer calves. Single nucleotide polymorphisms within four candidate genes including Thyroglobulin (TG), Adiponectin (ADPOQ), Insulin like growth factor-1 (IGF-1), and Calpastatin (CAST) were chosen for analysis. A total of 14 SNP on TG, ADPOQ, CAST, and IGF-1 genes were significantly associated with birth weight and weaning weight. Analysis revealed 13 SNP on TG, ADPOQ, IGF-1, and CAST genes significantly associated (P<.05) with HCW, BF, MS, and YG. No markers were reported to be significantly associated (P<.05) with HH or REA. A total of 11 markers with 3 markers located on the ADPOQ gene, 1 marker located on the IGF-1 gene, 3 markers located on the TG gene, and 5 markers located on the CAST gene were significantly associated with both growth and carcass traits.

Screening For Halosulfuron Tolerance And Identifying Ethylene Response Genes In Sweetpotato[Ipomoea Batatas (Lam) L.], Michael Polozola Jan 2014

Screening For Halosulfuron Tolerance And Identifying Ethylene Response Genes In Sweetpotato[Ipomoea Batatas (Lam) L.], Michael Polozola

LSU Master's Theses

Weeds cause significant yield loss in sweetpotato. Post-emergent herbicides cause damage to sweetpotato plant, which necessitates development of herbicide tolerant sweetpotato. An optimal tissue culture system is a prerequisite for in vitro screening of herbicide tolerant sweetpotato. Three Louisiana cultivars, ‘Beauregard’, ‘Orleans’, and ‘LA 07-146’, were tested to develop an efficient callus induction and plant regeneration system. 2, 4-D @ 0.23 µM was ideal for ‘Beauregard’ and ‘Orleans’ callus induction and 0.45 µM 2, 4-D for callus induction in ‘LA 07-146’. Phytohormone-free media was found suitable for regeneration. Plants were regenerated from callus tissues that survived in vitro with 2 …

Journalism And The "Dark Arts" - A Comparative Study Of British And American Media Ethic Codes Against The Backdrop Of The British Phone Hacking Scandal, Paromita Saha Jan 2014

Journalism And The "Dark Arts" - A Comparative Study Of British And American Media Ethic Codes Against The Backdrop Of The British Phone Hacking Scandal, Paromita Saha

LSU Master's Theses

The British phone hacking scandal in 2011 raised questions about the influence of powerful media conglemorates, most notably, Rupert Murdoch’s News Corporation, on the culture of the media and democracy on both sides of the Atlantic. Both American and British media are the world’s leading examples of a free market press built on the same ideological foundations. This study argues that the phone hacking scandal calls for a revised and nunanced look at the differences and similarities between the American and British media systems. This comparative analysis uses British and American news media ethic codes as an unit of analysis. …

Can Gravitational Influences Explain Endpoint Precision Between Visual Conditions?, Chelsea Marie Soebbing Jan 2014

Can Gravitational Influences Explain Endpoint Precision Between Visual Conditions?, Chelsea Marie Soebbing

LSU Master's Theses

Reaches to remembered target locations often result in different endpoint precision when compared to reaches to actual (seen) targets. Interestingly, errors are observed whether the reach to the remembered location is performed in an environment with or without allocentric cues (visual cues from the environment) available. People tend to point below remembered target locations in the dark relative to normal room lighting while seated, standing, and reaching with a step. In this study we questioned the effect of gravitational influences on upper extremity reaching and pointing accuracy in dark and illuminated environments. We hypothesized that alterations in body orientation would …

Minimization Of Transportation, Installation And Maintenance Operations Costs For Offshore Wind Turbines, Tasnim Ibn Faiz Jan 2014

Minimization Of Transportation, Installation And Maintenance Operations Costs For Offshore Wind Turbines, Tasnim Ibn Faiz

LSU Master's Theses

Although it is a sustainable source and there is abundant potential for energy, cost of energy generated from offshore wind is still high compared to other sustainable energy sources. Apart from the manufacturing cost of turbines, cost of energy is significantly affected by costs of transportation and installation operations of wind turbines and maintenance operations of turbine components. Through optimum selection of decision variables, such as turbine installation method and rated power output of each turbine, cost of transportation and installation operations can be minimized. The first model in this study investigates the impact of these decision variables and effect …

Palynology Of The Upper Cretaceous Ferron-Notom Sandstone, Utah, Isil Akyuz Jan 2014

Palynology Of The Upper Cretaceous Ferron-Notom Sandstone, Utah, Isil Akyuz

LSU Master's Theses

ABSTRACT The Late Cretaceous Ferron-Notom Sandstone Member of the Mancos Shale Formation plays a dominant role in oil production in Utah. Although numerous sedimentological and sequence stratigraphic studies have been conducted in recent years on this sequence, palynological analyses had not yet been undertaken. Here we present palynological data from one hundred twenty eight samples collected in the Ferron-Noton Sandstone Member outcroping in south-central Utah. The purpose of this study is to refine our understanding of climatic and depositional environments and to build a biostratigraphic palynological framework. The dominance of terrestrial palynomorphs, especially the high yield in moisture-loving cryptogam spores …

Species Composition And Spatial Ecology Of Amazonian Understory Mixed-Species Flocks In A Fragmented Landscape, Karl Mokross Jan 2014

Species Composition And Spatial Ecology Of Amazonian Understory Mixed-Species Flocks In A Fragmented Landscape, Karl Mokross

LSU Doctoral Dissertations

With the ongoing advance of the agricultural frontier in the Amazon basin, it is inevitable that heterogeneous landscapes will play a key role in conservation. These landscapes are mostly composed of patchworks of small forest fragments, secondary forests and roads. Conservation, however must take species interactions into consideration as they play a pivotal part the maintenance of several biological processes in the tropics. One of the most conspicuous interspecific interactions are seen in mixed-species flocks of birds, which in the Amazon, represent one of the best organized systems of bird aggregations. In this research, I assess how flock spatial behavior …

The Pulpit And The Nation: Clergymen, Political Culture, And The Creation Of An American National Identity, Spencer W. Mcbride Jan 2014

The Pulpit And The Nation: Clergymen, Political Culture, And The Creation Of An American National Identity, Spencer W. Mcbride

LSU Doctoral Dissertations

This dissertation examines the politicization of clergymen during the American Revolution and explains the direct impact this process had on the development of a national polity and a distinct American national identity in the early republic. Both during and after the Revolution, clergymen utilized providential rhetoric and biblical symbolism to assign greater religious and moral significance to political events. Focusing on the period between 1775 and 1800, this dissertation describes and analyzes the extent to which national political leaders relied on local clergymen when securing independence and thereafter inventing a new nation. Ultimately, it argues that clergymen were essential to …

A Case Study Of Tracie Morris's Project Princess, Tammie Jenkins Jan 2014

A Case Study Of Tracie Morris's Project Princess, Tammie Jenkins

LSU Doctoral Dissertations

In this study, I explore the intertextuality in spoken word poetry using Tracie Morris’s spoken word poem Project Princess (1998) as a case study. My hypothesis is that the intertextuality in spoken word poetry is derived from its genealogical contributions. Using narrative inquiry, I investigate Project Princess as page poetry and oral performance text anchored in the genealogy of spoken word poetry. The following research questions guided this study: How does intertextuality function in Tracie Morris’s spoken word poem Project Princess? What role does the genealogy of spoken word poetry play in understanding the intertextuality in Tracie Morris’s spoken word …

Conical Representations For Direct Limits Of Riemannian Symmetric Spaces., Matthew Glenn Dawson Jan 2014

Conical Representations For Direct Limits Of Riemannian Symmetric Spaces., Matthew Glenn Dawson

LSU Doctoral Dissertations

We extend the definition of conical representations for Riemannian symmetric space to a certain class of infinite-dimensional Riemannian symmetric spaces. Using an infinite-dimensional version of Weyl's Unitary Trick, there is a correspondence between smooth representations of infinite-dimensional noncompact-type Riemannian symmetric spaces and smooth representations of infinite-dimensional compact-type symmetric spaces. We classify all smooth conical representations which are unitary on the compact-type side. Finally, a new class of non-smooth unitary conical representations appears on the compact-type side which has no analogue in the finite-dimensional case. We classify these representations and show how to decompose them into direct integrals of irreducible conical …

Essays On Poverty And Infant Health, Deokrye Baek Jan 2014

Essays On Poverty And Infant Health, Deokrye Baek

LSU Doctoral Dissertations

In this dissertation, I offer three independent studies that each contribute to the literature on poverty and infant health. The first essay examines whether access to public transportation reduces food insecurity in the U.S. Potential endogeneity problem is addressed with instruments of federal transportation funding. I provide new evidence of a negative causal effect of public transportation accessibility on food insecurity, which is more prominent among poor African-American households. The second essay examines the relation between savings of poor households and a welfare program called the Supplemental Nutritional Assistance Program (SNAP). Eligibility for SNAP benefits requires households to own limited …

Applications Of Cfd Simulations On Studying The Multiphase Flow In Microfluidic Devices, Yuehao Li Jan 2014

Applications Of Cfd Simulations On Studying The Multiphase Flow In Microfluidic Devices, Yuehao Li

LSU Doctoral Dissertations

Microfluidics has been extensively investigated as a unique platform to synthesize nanoparticles with desired properties, e.g., size and morphology. Compared to the conventional batch reactors, wet-chemical synthesis using continuous flow microfluidics provides better control over addition of reagents, heat and mass transfer, and reproducibility. Recently, millifluidics has emerged as an alternative since it offers similar control as microfluidics. With its dimensions scaled up to millimeter size, millifluidics saves fabrication efforts and potentially paves the way for industrial applications. Good designs and manipulations of microfluidic and millifluidic devices rely on solid understanding of fluid dynamics. Fluid flow plays an important role …

Web-Based Computational Tools For Studying Plant Biodiversity, Timothy Mark Jones Jan 2014

Web-Based Computational Tools For Studying Plant Biodiversity, Timothy Mark Jones

LSU Doctoral Dissertations

Large scale plant biodiversity bioinformatics projects are now making taxonomic datasets available at a frenetic pace via the World Wide Web (WWW). While these new resources provide the fundamental textual and visual backbone of expert level knowledge, their information structure often impedes the development of derivative works for identification. But when this information is rearranged from a traditional format, questions can be asked of the data that were previously thought to be unanswerable. The difficulty in transforming this ‘big-data’ is manifold: how to deliver it rapidly to researchers across the world while providing visualizations of data that encompass these large …

Characterization Of Cry1f Resistance In Fall Armyworm, Spodoptera Frugiperda (J.E. Smith) Obtained From Puerto Rico And Florida, Vikash Dangal

LSU Master's Theses

The fall armyworm (Spodoptera frugiperda (J. E. Smith)) is a major pest targeted by transgenic corn expressing Bacillus thuringiensis (Bt) proteins in both North and South America. The objective of this study was to characterize the inheritance and fitness costs of the Cry1F resistance in two fall armyworm populations collected from Puerto Rico (RR-PR) and Florida (RR-FL). To determine the inheritance of the resistance, besides RR-PR, RR-FL, and a Cry1F-susceptible population (Bt-SS), 14 other populations were developed by reciprocal crosses, F1 by F1 crosses, backcrosses, and crosses between RR-PR and RR-FL. Diet-incorporated bioassays were conducted to determine the Cry1F susceptibility …

Exponentially Convergent Generalized Finite Element Method For Multi-Scale Problems, Xu Huang Jan 2014

Exponentially Convergent Generalized Finite Element Method For Multi-Scale Problems, Xu Huang

LSU Doctoral Dissertations

The overall approach I take in the thesis falls into the category of multiscale finite element methods(MsFEM). I work to identify a new class of local approximation spaces with good approximation properties. This is carried out for the equilibrium problem of linear elasticity. The choice of local approximation spaces is motivated by the kolmogorov n-width. Part of my thesis work develops an estimate to show that it is possible to achieve a local approximation error of ô with respect to the energy norm using at most lnd+1 &frac1ô local basis functions. The global approximation error ôis controlled by the …

Substitution And Disorder Effects In Ternary Intermetallics, Larico Juan Treadwell Jan 2014

Substitution And Disorder Effects In Ternary Intermetallics, Larico Juan Treadwell

LSU Doctoral Dissertations

The focal point of this dissertation is the investigation of substitution and disorder effects in ternary intermetallics. The crystal growth, crystal structure, and physical properties are reported on single crystals of Ln6W4-xAl43-yTx+y (Ln = Gd, Yb; T= Mn, Fe), LnCr2FexAl20-x (Ln = Yb, Gd), Sm1.33Pd3Ga8, and CeCo2-xMxAl8 (M = Mn, Fe, Ni; 0 ≤ x < 1). The reported compounds were grown via the flux growth method with the strategic synthetic parameters described. Correlations between the structural and physical properties in relation to substitution and disorder of Ln6W4-xAl43-yTx+y (Ln = Gd, Yb; T= Mn, Fe), LnCr2FexAl20-x (Ln = Yb, Gd), Sm1.33Pd3Ga8, and CeCo2-xMxAl8 (M = Mn, Fe, Ni; 0 ≤ x < 1) are discussed. The synthesis and characterization of Mn- and Fe- substituted Ln6W4Al43 (Ln = Gd, Yb) are reported. The compounds adopt the Ho6Mo4Al43 structure type with lattice parameters of a ~ 11 Å and c ~ 17.8 Å with structural site preferences for Mn and Fe. The magnetization of Yb6W4Al43 is sensitive to Mn and Fe doping, which is evident by an increase in the field dependent magnetization. Gd6W4Al43, Gd6W4Al42.31(11)Mn0.69(11), and Gd6W4Al41.69(12)Fe1.30(12) order antiferromagnetically in the ab- and c-direction at 15, 14, and 13 K, respectively, with positive Weiss constants, suggesting the presence of ferromagnetic exchange interactions. Anisotropic magnetization data of Gd6W4Al43-yTy (T= Mn, Fe) analogs are discussed. Crystal growth, structure determination, and magnetic properties of LnCr2Al20-xFex (Ln = La, Gd, Yb) adopting the CeCr2Al20 structure type with space group Fd3¯ m, a ~ 14.5 Å, type are reported. Single crystal X-ray diffraction and Mössbauer spectroscopy are employed to fully characterize the crystal structure of LnCr2Al20-xFex (Ln = La, Gd, Yb). LnCr2Al20-xFex (Ln = La, Gd, Yb) are the first pseudo-ternaries adopting the CeCr2Al20 structure type with a transition metal occupying the main group site. The Yb analogues are Pauli paramagnets with the Yb ion adopting an electronic configuration close to Yb2+, while the Gd analogues show paramagnetic behavior with no magnetic order down to 3 K. The synthesis and characterization of Sm1.33Pd3Ga8 is reported. Sm1.33Pd3Ga8 adopts a disordered variant of the Er4Pt9Al24-structure type with lattice parameters of a = 4.353(5) and c = 38.98(4) Å and V = 639.70(12) Å3. The structure of Sm1.33Pd3Ga8 is composed of three distinct building blocks: Pd2Ga4, PdGa2, and Sm0.67Ga. The Sm0.67Ga slab does not magnetically order, which directly affect the structure. Sm1.33Pd3Ga8 is a temperature independent paramagnet. Field dependent magnetization of Sm1.33Pd3Ga8 displays anisotropic behavior. Single crystals of CeCo2-xMxAl8 (M = Mn, Fe, Ni; 0 ≤ x < 1) were grown and crystallize in the CaCo2Al8 structure type with space group Pbam. Single crystal X-ray diffraction data suggest that the Ce 4f-state is valence fluctuating as Fe concentration increases, whereas the Ni-doped analogues do not exhibit valence fluctuating. The results suggest that hole doping leads to an admixture of Ce3+/Ce4+.

Intersections Of Race And Class In 1830s Othello Burlesques, Laura Michelle Keigan Jan 2014

Intersections Of Race And Class In 1830s Othello Burlesques, Laura Michelle Keigan

LSU Doctoral Dissertations

In recent years, we have come to better understand how nineteenth-century burlesques critiqued and lampooned the respectable humbuggery of patent theater productions and middle-class culture. Their carnivalesque spectacle and low humor turned topsy-turvy what was falsely revered or pretentious in English society. This study, however, explores the extent to which some burlesques responded conservatively to social and legislative change, which supposedly weakened established hierarchies constituting English culture and society. My chapters examine how two burlesques of Shakespeare’s Othello—Charles M. Westmacott’s Othello, the Moor of Fleet Street (1833) and Maurice M. M. G. Dowling’s Othello Travestie (1834)—contributed to discourse surrounding debate …

Militant Feminism And The Women Of The Weather Underground Organization, Mona Cristina Rocha Jan 2014

Militant Feminism And The Women Of The Weather Underground Organization, Mona Cristina Rocha

LSU Doctoral Dissertations

Militant feminism is characterized by two positions. First, the militant feminist believes that where the use of violence is justified, it is just as justified when performed by women as by men. Second, militant feminists hold that militant action can be justified in the pursuit of aims consistent with feminist values. Shortly after the emergence of second-wave feminism in the mid-1960’s, there is a surge of militant feminists among radical leftist organizations, such as the Weather Underground Organization. Second-wave feminists articulated a view of womanhood that was not confined to the home; militant feminists, such as those of the Weather …

Spin-Mediated Transport In Superconducting And Spin-Polarized Systems, Joseph C. Prestigiacomo Jan 2014

Spin-Mediated Transport In Superconducting And Spin-Polarized Systems, Joseph C. Prestigiacomo

LSU Doctoral Dissertations

The effects of spin-imbalance on the electronic transport properties of spin-polarized and superconducting systems have been studied in detail. The transport properties of the quaternary Heusler alloys Co2MnSi1-xAlx (0≤x≤1), which have been theoretically predicted to develop a half-metallic band structure as x→0, were investigated. Resistivity versus temperature measurements as a function of Al concentration (x) revealed a systematic reduction in the residual resistivity ratio as well as a transition from weakly-localized to half-metallic conduction as x→0. From measurements of the ordinary and anomalous Hall effects, the charge carrier concentration was found to increase, while the anomalous Hall coefficient decreased by …
