▼ Mass transport limitations and surface interactions are important phenomena in microfluidic devices. The flow of water is laminar at small scales and the absence of turbulent mixing can lead to transport limitations, especially for reactions that take place at surfaces. Microscale devices have a high ratio of surface area to volume, and proteins are known to adsorb preferentially at interfaces. Protein adsorption plays a significant role in biology by mediating critical processes such as the attachment of cells to surfaces, the immune response and the coagulation of blood. Simulation tools that can quantitatively predict transport and protein adsorption will enable the rational design of microfluidic devices for biomedical applications. Two-dimensional random sequential adsorption (RSA) models are widely used to model the adsorption of proteins on surfaces. As Brownian dynamics simulations have become popular for modeling protein adsorption, the interface model has changed from two-dimensional to three-dimensional. Brownian dynamics simulations were used to model the diffusive transport of hard-sphere particles in a liquid and the adsorption of the particles onto a uniform surface. The configuration of the adsorbed particles was analyzed to quantify the chemical potential near the surface, which was used to derive a continuum model of adsorption that incorporates the results from the Brownian dynamics simulations. The equations of the continuum model were discretized and coupled to a conventional computational fluid dynamics (CFD) simulation of diffusive transport to the surface. The kinetics of adsorption iii predicted by the continuum model closely matched the results from the Brownian dynamics simulation. This new model allows the results from mesoscale simulations to be used as a boundary condition for micro- or macro-scale CFD simulations of transport and protein adsorption in practical devices. Continuum models were used to interpret experimental measurements of the kinetics of protein adsorption. A Whispering Gallery Mode (WGM) biosensor was constructed and used to measure the adsorption of fibronectin (FN) and glucose oxidase (GO) onto several types alkysilane self-assembled monolayers (SAMs). Computational fluid dynamics was used to model the transport of protein in the flow cell of the biosensor. Various models were fitted to the experimental data, taking into account the transport limitations predicted by the CFD simulations. The fitted parameter values and the quality of fit of the various models were analyzed to test hypotheses about the mechanisms of adsorption. Cells were cultured on silane surfaces coated with FN to assess its biological activity, and a colorimetric assay was used to determine the enzymatic activity of the adsorbed glucose oxidase. The results of the GO activity assay were compared to the activity predicted by the models. The WGM biosensor, transport simulation and kinetic model fitting enabled new insights into the adsorption of proteins on functionalized surfaces at solution…

▼ There is a labyrinth of complex social connections between people and places that deserves careful anthropological reflection. People do not simply occupy places; they experience them, infusing them with life and social meaning. Basso (1996:53) argues that ethnography has reported little about the complex ways in which people are “alive to the world around them.” Anthropology is currently experiencing a resurging emphasis on place that seeks to account for its remarkably social features. Rather than primarily thinking about place when determining a location for fieldwork, emerging anthropological reflection shows the discipline is repositioning itself to explore the complex and often fantastic ways people experience, conceptualize, and confer meaning to their natural surroundings. In anthropology, the phrase “sense of place” captures these ideas. The phenomenological approach has emerged as the theoretical centerpiece for this effort, promising to open extraordinary new pathways for qualitative exploration. This thesis uses the life history methodology to explore how two female Palestinian immigrants to Central Florida experience and confer meaning to their ancestral homeland and place of birth. Data collected through a series of life history interviews highlight the texture of Palestinian senses of place, including the presence of what I describe as an eschatological sense of place.

▼ This study used indirect methods to estimate patterns of gene flow in a rare salamander species, the striped newt (Notophthalmus perstriatus). First, we used combined genetic and ecological methods to determine whether populations that appear to exist in two regions separated by 125 km, exhibited genetic and ecological distinctness such that the regions demarcate separate conservation units. Using mtDNA (cyt-b), we found that haplotypes were shared between localities within each region but none were shared between regions. Niche-based distribution modeling revealed significant differences in the ecological setting between the two regions. In combination, the absence of evidence for recent genetic exchange and model-based support for differing ecological conditions utilized by newts between regions provides evidence that eastern and western populations are both distinct and significant. This study suggests a framework to evaluate discreteness and significance among populations for assessment of distinct population segments (DPSs which can be used as a conservation tool for many species. Second, we used microsatellites to characterize patterns of population connectivity, genetic differentiation, and effective population size in N. perstriatus. We assessed these patterns by testing several a priori hypotheses regarding the influence of gene flow and genetic drift on the distribution of genetic variation among and within populations. Interestingly, several of our results did not conform to our hypotheses. For example, our assessment did not reveal a significant pattern of isolation by distance among populations in this study. Additionally, we found that effective population sizes and genetic diversity of isolated populations were higher than expected. We discuss our results relate to our a priori hypotheses and we address the general question of why this species exhibited patterns contrary to what we expected given previous data on this taxon and other studies of similar taxa.

▼ A taxonomy of achievement design features that exist currently in video game systems was created in order to evaluate the current the state of the art in achievement design. From the taxonomy of design features multiple mechanisms of action that influence player behavior were identified. These mechanisms lead to a predictive model that can guide the designs of achievements in order to improve performance, self-efficacy and motivation in players. Expected, unexpected, and incremental achievements were tested. Notifications occurring before and after earning an achievement were also tested. In addition to testing individual mechanisms of action a “combined achievement” was created with multiple mechanisms added that were hand-picked. For testing purposes the model was applied to achievements that were inserted into an instructional game. The results of the study revealed that individual mechanisms of action had little effect on players while multiple mechanisms in a combined achievement caused significant improvements in several categories. The limitations of the current study, as well as, plans for future study are also discussed.

▼ This thesis addresses the dynamics of estuarine networks, based on hydrographic observations in Newark Bay, a sub-estuarine network connected to the Hudson River estuary through New York Harbor. Estuarine networks differ from simple estuaries in that they may have multiple connections to the ocean, multiple freshwater sources, and often contain complex junctions between estuarine segments. The Newark Bay estuarine network is connected to the sea through two tidal straits, and is fed by multiple internal and external sources of fresh water. The estuarine network is also naturally divided into a series of reaches, each of which is characterized by a different cross-sectional geometry. This thesis focuses on the hydrographic variability and varying exchange flow within the Newark Bay estuarine network. Shipboard hydrographic measurements reveal the time-dependent formation
of salinity fronts between reaches of the estuary. Each front is generated by a different mechanism; however, all are generated by tidal flow through channel junctions during ebb tide, and are advected landward during flood tide. Mooring-based measurements confirm that these fronts form during nearly every tidal cycle, and that the fronts are associated with substantial changes in local salinity on tidal timescales. The effect of tidal processes, such as frontal advection, on the exchange flow is investigated by applying the isohaline total exchange flow (TEF) framework to mooring-based observations in multiple reaches of
the estuarine network. This reveals that over half of the exchange flow is driven by tidal processes at all sites within the estuary. Both the TEF-based salt balance and the standard Eulerian salt balance indicate that tidal processes are also responsible for at least half of the landward salt flux at most sites within the estuary; TEF and Eulerian salt balances are nearly identical. Tidal processes within the estuary are in large part associated with fronts. The large influence of tidal processes on the exchange flow in Newark Bay is thus likely due to the prevalence of channel junctions within the estuarine network.

▼ The formation of Tharsis rise on Mars is a highly debated topic. Tharsis topography is
very localized within the global terrain of Mars. The timing of Tharsis formation likely
occurred early in Mars history in the Noachian but post dates the hemispheric crustal
dichotomy which it overprints. Several models have been proposed to explain a localized
orogeny, but use of boundary layer theory or convection studies result in multiple, evenly
spaced plumes or have instability growth and rise times which are longer than estimates
for Tharsis formation. We propose a new model which couples the early differentiation
processes of the Mars interior and Tharsis formation. Here we conduct physical fluid
dynamic experiments of core formation using high viscosity glucose syrup and an
emulsion of liquid, metal gallium. Melting due to impacts during accretion may induce
silicate-metal separation and form a liquid iron pond that settles temporarily at the base of
the magma ocean. Thus we design our experiments as a two component fluid system with
a metal pond at the interface. Previous experiments using a smooth liquid diapir observed
three regimes for conduit formation where 1) low density conduit material is entrained
and descends through the conduit, 2) reverses flow direction once the metal diapir
reaches the base, and 3) travels back to the surface emptying out the conduit causing it to
collapse. In our experiments with an emulsion diapir, we find that only regimes 1 and 3
are observed within the conduit. This is due to the fact that the return flow of buoyant
conduit material does not occur within the conduit, but is forced to exit the conduit by the
second stage of falling emulsion drops and travels to the surface as a buoyant thermochemical
plume along its own path. A 2nd stage of small thermo-chemical plumes are
observed to rise to the surface as they separate from the 2nd stage of sinking metal
emulsion drops. This study suggests a thermo-chemical plume, which forms as a
secondary effect of core formation, may explain the formation of a localized orogeny
such as the Tharsis rise on Mars. Fluid experiments scaled to the planetary mantle interior
indicate that the time for a metal-silicate plume to sink to the core, separation of silicate
from liquid metal, growth of a buoyant thermo-chemical plume, and subsequent rise to
the surface is on the order of 1-8 My. This model is consistent with several observations
for Tharsis formation including rapid formation within the Noachian, the requirement of
a single large upwelling soon after core formation, arrival of a plume after formation of
the crustal dichotomy, as well as later effusive stages of volcanism on Tharsis observed
up to the Amazonian.

▼ The San Gorgonio Pass fault zone is a thrust-dominated, complex fault system, that connects strike-slip segments of the southern San Andreas fault. The structural complexities of the Pass region are considered by some to be a barrier to through-going San Andreas fault ruptures. Understanding the rupture history of this region is key to forecasting large earthquakes along the southern San Andreas fault. (See more in text.)

▼ The San Andreas Fault (SAF) is surrounded by several rigid blocks which may add stress and increase seismic hazards locally. Although the rotation of tectonic blocks such as the Western Transverse Ranges (WTR) has been well documented the physics, rheology and stresses across the plate boundary due to the rotation have yet to be addressed in the context of a computational problem which can constrain these parameters. Here I perform 2-D and 3-D computational experiments modeling the region surrounding the SAF using particle-in-cell finite element modeling. My experiments vary viscosity contrast between the surrounding region, rigid blocks, and a weak zone which defines the SAF. I impose a velocity on one side of the box and solve for particle velocities to vary everywhere in the model space. My experiments show viscosity contrast between the region of interest and the degree of weakness of a fault plays an important role in the deformation field. My results suggest that stronger deformation is observed when the viscosity contrast increases. The presence of a rigid block near the leading bend causes more strain outside of the bend. This is exemplified by studies showing more transpressional fault behavior near the leading bend (where the adjacent WTR adds stress) compared to the trailing bend of the SAF. I also model the WTR near the Big Bend with a centrally located rigid block. My model predicts the presence of the WTR will cause strain to be concentrated at the Big Bend and the trailing bend of the SAF. I observe internal deformation within the block that models the WTR which may be consistent with numerous sinistral faults and active deformation. Models of a rigid block near the trailing bend suggest that if such a block exists near the trailing bend of the SAF, the bend should become less sharp and more diffuse due to block rotation which creates curvature in the linear fault. The 3-D results consider a non-vertical fault and show that increasingly shallow dip angles produce more strain on the side of the fault indicated by the dip direction.

▼ A set tiles the integers if and only if the integers can be written as a disjoint union of translates of that set. Counterexamples based on finite Abelian groups show that Fuglede conjecture is false in high dimensions. A solution for the Fuglede conjecture in Z or all the groups ZN would provide a solution for the Fuglede conjecture in R. Focusing on tiles in dimension one, we will concentrate on the analysis of tiles in the finite groups ZN. Based on the Coven- Meyerowitz conjecture, it has been proved that if any spectral set in Z satisfies the the Coven-Meyerowitz properties, then every spectral set in R is a tile. We will present some of the main results related to integer tiles and give a self-contained description of the theory with detailed proofs.

The Application Of Chemometrics To The Detection And Classification Of Ignitable Liquids In Fire Debris Using The Total Ion Spectrum.

(more)
▼ Current methods in ignitable liquid identification and classification from fire debris rely on pattern recognition of ignitable liquids in total ion chromatograms, extracted ion profiles, and target compound comparisons, as described in American Standards for Testing and Materials E1618-10. The total ion spectra method takes advantage of the reproducibility among sample spectra from the same American Society for Testing and Materials class. It is a method that is independent of the chromatographic conditions that affect retention times of target compounds, thus aiding in the use of computer-based library searching techniques. The total ion spectrum was obtained by summing the ion intensities across all retention times. The total ion spectrum from multiple fire debris samples were combined for target factor analysis. Principal components analysis allowed the dimensions of the data matrix to be reduced prior to target factor analysis, and the number of principal components retained was based on the determination of rank by median absolute deviation. The latent variables were rotated to find new vectors (resultant vectors) that were the best possible match to spectra in a reference library of over 450 ignitable liquid spectra (test factors). The Pearson correlation between target factors and resultant vectors were used to rank the ignitable liquids in the library. Ignitable liquids with the highest correlation represented possible contributions to the sample. Posterior probabilities for the ASTM ignitable liquid classes were calculated based on the probability distribution function of the correlation values. The ASTM ignitable liquid class present in the sample set was identified based on the class with the highest posterior probability value. iv Tests included computer simulations of artificially generated total ion spectra from a combination of ignitable liquid and substrate spectra, as well as large scale burns in 20’x8’x8’ containers complete with furnishings and flooring. Computer simulations were performed for each ASTM ignitable liquid class across a range of parameters. Of the total number of total ion spectra in a data set, the percentage of samples containing an ignitable liquid was varied, as well as the percent of ignitable liquid contribution in a given total ion spectrum. Target factor analysis was them performed on the computer-generated sample set. The correlation values from target factor analysis were used to calculate posterior probabilities for each ASTM ignitable liquid class. Large scale burns were designed to test the detection capabilities of the chemometric approach to ignitable liquid detection under conditions similar to those of a structure fire. Burn conditions were controlled by adjusting the type and volume of ignitable liquid used, the fuel load, ventilation, and the elapsed time of the burn. Samples collected from the large scale burns were analyzed using passive headspace adsorption with activated charcoal strips and carbon disulfide desorption of volatiles for analysis using gas…

▼ Gas giant exoplanets known as hot Jupiters orbit close to their parent stars and are heated to high temperatures. Their infrared spectra, measured by photometry during secondary eclipses, are dominated by carbon monoxide and methane, the principle reservoirs of carbon on these planets. The relative CO and CH4 abundances inform us about temperature and pressure conditions and also about mixing by global winds driven by intense but asymmetric heating for these tidally locked bodies. Emission spectra collected during secondary eclipses, as the hot Jupiter passes behind its parent star, in principle allows a determination of the CO:CH4 concentration ratio. Since hot Jupiters exist at temperatures of order 700 K, accurate model atmospheres require high temperature line lists for relevant molecules, for which existing data bases are apparently incomplete. Since the outer atmospheres of hot Jupiters are bombarded by intense ultraviolet radiation and energetic particles, there may even be a significant degree of ionization and nonequilibrium populations among the various molecular levels. Here we present high temperature emission spectra of CO obtained from a microwave discharge plasma, where the source of CO was carbon dioxide that dissociates under microwave heating. The spectrum was measured in the range 1800-2400 cm-1 at a resolution of 0.1 cm-1 . Vibrational transitions originating in up to the 13th vibrational level of the X 1 + ground electronic term were observed. From the J values for maximum intensity lines within the rotational fine structure, we obtain a temperature estimate of ~700 K, which is comparable to the atmospheric conditions of hot-Jupiters.

▼ In this dissertation, we generalize the work of Bender and co-workers to derive new partially-integrable hierarchies of various PT -symmetric, nonlinear partial differential equations. The possible integrable members are identified employing the Painlev´e Test, a necessary but not sufficient integrability condition, and are indexed by the integer n, corresponding to the negative of the order of the dominant pole in the singular part of the Painlev´e expansion for the solution. For the PT -symmetric Korteweg-de Vries (KdV) equation, as with some other hierarchies, the first or n = 1 equation fails the test, the n = 2 member corresponds to the regular KdV equation, while the remainder form an entirely new, possibly integrable hierarchy. Integrability properties of the n = 3 and n = 4 members, typical of partially-integrable systems, including B¨acklund Transformations, a ’near-Lax Pair’, and analytic solutions are derived. The solutions, or solitary waves, prove to be algebraic in form, and the extended homogeneous balance technique appears to be the most efficient in exposing the near-Lax Pair. The PT -symmetric Burgers’ equation fails the Painlev´e Test for its n = 2 case, but special solutions are nonetheless obtained. Also, PT -Symmetric hierarchies of 2+1 Burgers’ and Kadomtsev-Petviashvili equations, which may prove useful in applications are analyzed. Extensions of the Painlev´e Test and Invariant Painlev´e analysis to 2+1 dimensions are utilized, and BTs and special solutions are found for those cases that pass the Painlev´e Test.

▼ We report a mechanism based screening technique to rapidly identify eukaryotic topoisomerase I targeting agents. The method is based on genetic tagging of topoisomerase I to immobilize the enzyme on a solid surface in a microtiter well format. DNA is added to the wells and retained DNA is detected by Picogreen fluorescence. Compounds that result in an increase in Picogreen staining represent potential topoisomerase interfacial poisons while those that reduce fluorescence report catalytic inhibitors; therefore, the solid phase assay represents a „bimodal‟ readout that reveals mechanisms of action. The method has been demonstrated to work with known interfacial poisons and catalytic inhibitors. In addition to specific topoisomerase targeting drugs, the method also weakly detects other relevant anticancer agents, such as potent DNA alkylating and intercalating compounds; therefore, topoisomerase I HTS represents an excellent tool for searching and identifying novel genotoxic agents. This method is rapid, robust, economical and scalable for large library screens.

▼ Urbanization is accelerating in the United States and is contributing to fragmentation of natural habitats, causing changes in species composition and declines in native species. Human population growth in Orlando is typical of growth in the southeastern United States and throughout the range of cypress (Taxodium distichum). Orlando has numerous isolated cypress wetlands, called cypress domes, and many remain among the current urbanized area. This makes Orlando ideal to study the effects of urbanization on cypress domes. Specifically, I tested how urbanization and its effects on fragmentation, hydrology, and fire regime) affected (a) the numbers and spatial pattern of cypress domes in central Florida and (b) the recruitment of cypress within cypress domes. Analysis of historical loss found over 3,000 cypress domes identified in images from1984, of which 26% were lost or degraded (i.e., no longer cypressdominated) by 2004. Due to changed land use, many remaining cypress domes, formerly surrounded by natural lands, have become surrounded by urban lands causing spatial clustering and homogenization. Surprisingly, I found that both natural and urban cypress domes showed lower recruitment than agricultural cypress domes, where the natural fire regime has not been altered. The probability of cypress recruitment in cypress domes urbanized for more than 20 years is very low. Previous to that, cypress tends to recruit on the edge of cypress domes where there is less competition and hydrological conditions are more favorable. I estimate that only ~50% of the current cypress domes are recruiting and the existence of those wetlands are tied to the lifespan of the current adults. By 2104, I estimate that ~89% of the cypress domes currently recruiting will fail to recruit. I believe that reducing urban sprawl and restoring the natural fire iii regime to natural cypress domes will mitigate the current fate of cypress domes. Without this, cypress in isolated wetlands in central Florida, and providing Orlando urbanization is typical, throughout urbanized areas of the range, could be at risk. Cypress in urban areas will be then relegated to riparian zones and with unknown consequences for the species that utilize the former cypress dome habitat

▼ Mean shift is an effective iterative algorithm widely used in image analysis tasks like tracking, image segmentation, smoothing, filtering, edge detection and etc. It iteratively estimates the modes of the probability function of a set of sample data points based in a region. Mean shift was invented in 1975, but it was not widely used until the work by Cheng in 1995. After that, it becomes popular in computer vision. However the convergence, a key character of any iterative algorithm, has been rigorously proved only very recently, but with strong assumptions. In this thesis, the method of mean shift is introduced systematically first and then the convergence is established under more relaxed assumptions. Finally, generalization of the mean shift method is also given for the estimation of probability density function using generalized multivariate smoothing functions to meet the need for more real life applications.

▼ For centuries, indigenous women have been forced to labor in slave-like conditions as domestic workers in Lima, Peru. With neoliberal practices on the rise, Peru’s domestic labor informal economic sector struggles with sociopolitical representation. The downtrodden women of the household work economy exemplify the national perception of desconfianza, or distrust, as it trickles down from the wealthier individuals to those living in poverty. Although the nature of domestic work is a product of hegemonic colonial relations and, recently, violent social movements in the late 20th century, increasing attempts for government transparency and nongovernmental involvement, have created a slowly recovering broken social system. In this thesis, I ascertain that the identity of trabajadoras, or female workers, is primarily driven by their agency as they struggle to become upwardly mobile.

▼ Individuals sensitive to domestic cat allergen Fel d 1 experience a variety of symptoms including eye irritation, respiratory irritation, asthma, and severe respiratory distress. Fel d 1 is a protein produced in the saliva and on the skin of domestic cats. Previous studies have demonstrated that Fel d 1 adheres to clothing, upholstery, and human hair and has been found in non-cat environments in levels high enough to cause allergic reactions in sensitive individuals. In a general sense, two very different approaches have been adopted to study Fel d 1. One area of the literature focuses on the molecular biology of Fel d 1 and its functions at the cellular level. These studies hold long-term promise for an effective clinical response to this persistent allergen. An entirely separate literature focuses on immediate practical solutions that remove Fel d 1 from the domestic environment. Within this literature there has been minimal emphasis on the possibility that different fabrics may have different affinities for Fel d 1. Therefore, the affinity of Fel d 1 for different fabrics is the focus of this study. The findings from this study will be of use in reducing allergic reactions in sensitive individuals through the choice of appropriate fabrics in clothing and upholstery. Forty domestic household cats were chosen for this study. Each cat was rubbed, in a manner similar to petting, with an assembled fabric square based on a Latin-square design. Each Latin-square design consisted of a 6x6 fabric grid and included the fabrics silk dupioni, wool suiting, cotton denim, cotton damask, polyester suede and polyester knit. The random organization of the fabrics into the grid removed bias for the location of fabrics within the square during Fel d 1 collection. After rubbing, the Latin-square fabric iii block was disassembled and Fel d 1 was extracted from each fabric type and analyzed via quantitative ELISA. The results were statistically analyzed with a univariate ANOVA. Fabrics significantly differ (p

▼ Iteratively reweighted least squares (IRLS) algorithms provide an alternative to the more standard 1 l -minimization approach in compressive sensing. Daubechies et al. introduced a particularly stable version of an IRLS algorithm and rigorously proved its convergence in 2010. They did not, however, consider the case in which prior information on the support of the sparse domain of the solution is available. In 2009, Miosso et al. proposed an IRLS algorithm that makes use of this information to further reduce the number of measurements required to recover the solution with specified accuracy. Although Miosso et al. obtained a number of simulation results strongly confirming the utility of their approach, they did not rigorously establish the convergence properties of their algorithm. In this paper, we introduce prior information on the support of the sparse domain of the solution into the algorithm of Daubechies et al. We then provide a rigorous proof of the convergence of the resulting algorithm.

▼ Small anthropomorphic figures, most often referred to as “Charlie Chaplins,” appear in ritual deposits throughout the ancient Maya sites of Belize during the late Preclassic and Early Classic Periods and later, throughout the Petén region of Guatemala. Often these figures appear within similar cache assemblages and are carved from “exotic” materials such as shell or jade. This thesis examines the contexts in which these figures appear and considers the wider implications for commonly held ritual practices throughout the Maya lowlands during the Classic Period and the similarities between “Charlie Chaplin” figures and anthropomorphic figures found in ritual contexts outside of the Maya area.

▼ This study examined the way gender operates in relation to time within the food work spectrum discussed in 19 narratives. The 19 narratives came from individual open ended face-to-face interviews with self-defined healthy men who shop at healthy food stores. This study's examination of how gender operates in the narratives was based on how the men constructed their experiences with women and work in relation to time through the food work spectrum. Women mentioned in the sampled narratives taught the men how to shop and eat in a healthy manner but women still did the cooking. Work wise the findings split the men into two groups, the majority were the men who did not eat at work and the minority were the ones who did. Both of these sets of findings illuminate that how the men constructed their experiences of the food work spectrum depended on gendered relations of power.

▼ The vegetarian social movement is a “new” social movement based in lifestyle and cultural change. New social movements hold a strong emphasis on collective identity and social networks as a means to sustain participation. The majority of the social movement literature remains focused on movement engagement and mobilization while a large gap exists regarding disengagement. This project explores the barriers to vegetarian maintenance. The primary question answered is, why do some vegetarians and vegans backslide and withdraw from the practice? Fourteen individuals were interviewed to discover the social and cultural factors inherent in vegetarian instability. Over the course of the interviews, the project morphed into an analysis of why and how my respondents changed their food habits over time and what was the context that prompted these changes. Vegetarianism is a unique movement as definitions of what constitutes a vegetarian is rooted in the individual, idiosyncratic biographies of individuals. This study found the influence of family, traditions, labels/definitions, peers, gender and the lure of social status to be very significant regarding vegetarian flux. Results indicate that vegetarian membership is fluid and permeable, takes on a life course trajectory and is rooted within the context of many social and cultural factors. Uncovering the barriers to vegetarianism not only adds to the disengagement aspect of social movement research, but also hopes to iv aid movement leaders in overcoming this problem as well as further substantiate and progress the vegetarian social movement.

▼ The purpose of the present dissertation is to study model selection techniques which are specifically designed for classification of high-dimensional data with a large number of classes. To the best of our knowledge, this problem has never been studied in depth previously. We assume that the number of components p is much larger than the number of samples n, and that only few of those p components are useful for subsequent classification. In what follows, we introduce two Bayesian models which use two different approaches to the problem: one which discards components which have “almost constant” values (Model 1) and another which retains the components for which between-group variations are larger than withingroup variation (Model 2). We show that particular cases of the above two models recover familiar variance or ANOVA-based component selection. When one has only two classes and features are a priori independent, Model 2 reduces to the Feature Annealed Independence Rule (FAIR) introduced by Fan and Fan (2008) and can be viewed as a natural generalization to the case of L > 2 classes. A nontrivial result of the dissertation is that the precision of feature selection using Model 2 improves when the number of classes grows. Subsequently, we examine the rate of misclassification with and without feature selection on the basis of Model 2.

▼ Thermally induced retro-Diels Alder (rDA) reaction has been extensively used for the preparation of many reactive intermediates in organic synthesis. But the uses of photo-retro Diels-Alder (PrDA) reaction in organic synthesis were sparingly reported in literature. Due to its spatial and temporal control, PrDA can be used in making of photosensitive materials, in drug delivery and also for mechanistic studies. Diels-Alder adducts of tetracyanoethylene (TCNE) and polyaromatic compounds (anthracene, napthacene, pentacene and phencyclone) were synthesized and were subjected to PrDA reaction through 254-nm irradiation. The quantum yield and the consequent photoreactivity of these DA adducts follow the following order. TCNE/naphthacene greater than] TCNE/anthracene greater than or equal to] TCNE/pentacene This trend was explained by a mechanism of charge-separated intermediates. The stability of the charge-separated intermediate is the governing factor of this trend of photoractivity of DA adducts. Based on these results it is possible to design a proper DA adduct and consequently predict the feasibility of the PrDA reaction.

▼ Maya Folktales offer insight into how twentieth century Maya worldview is a hybrid of indigenous Maya and European beliefs. Analysis was conducted on twenty-eight Maya folktales from the highlands of Guatemala found in folklore anthologies. Stories like The Spirits of the Dead in folklore anthologies can reveal new perspectives on how the Maya feel about rituals spaces, the fabric that separates the land of the dead from the land of the living, and the importance of showing respect to the dead in one’s community. Other stories, show the connection the Maya feel with their heritage and the connection they feel with the area where their ancestors lived. Twentieth century Maya folktales can provide insight into how the Maya view their landscape, including the realm of the dead as a part of the physical landscape and the belief that the landscape itself is a living spiritual entity.

▼ The purpose of this research is to examine women‟s attitudes toward homosexuality by religiosity, and how these attitudes may vary across denominations. To examine this, I will use the General Social Survey to analyze the extent to which women‟s attitudes toward same-sex relations vary by denominational affiliation, religious participation, and spirituality. Based on the current literature, women are generally considered to be more tolerant than men regarding homosexuality. However, research has not examined the extent to which their attitudes vary across denominational affiliation. This research will contribute to the current literature by examining variations by denomination, religiosity, and spirituality in regards to women‟s attitudes on a controversial, hot-button issue in our society. Following the analysis and explanation of the results, directions for future research are discussed.

▼ In U.S. society, the systems of gender and race operate to privilege and oppress individuals based on their location within these systems. All of the interactions an individual experiences as they go about their day-to-day lives are shaped by these interlocking systems. As a result, there is an extensive body of sociological literature addressing how individuals in U.S. society are privileged and oppressed on the basis of their perceived membership in gender and race categories; however, relatively little research exists examining how individuals come to be seen by others as members of gender and race categories in the first place. In order to address this gap in the existent literature, this thesis asked 354 participants to perform gender and race categorizations for 28 target individuals of various gender and race category memberships. Participants were asked to make a categorization, rate how confident they were in that categorizations accuracy, and then explain why they made the gender or race categorization that they did. In analyzing these categorizations, this thesis produced three important findings about the process of gender and race categorization. First, this thesis identified two gender categories ("female" and "male") and eight race categories ("White," " Black," "Latino," "Asian," "Southeast Asian," "South Asian/Indian," "Middle Eastern," and "Mixed Race") used in gender and race categorization. Second, particularly in the common usage of the biologically-based concepts of "sex" and "race," rather than the socially-based concepts of "gender" and "ethnicity." Third, this thesis found interactions between the gender and race systems in categorization, finding that White individuals and male individuals are gender categorized more easily than Black individuals or female individuals, and individuals will less "ambiguous" skin coloration are more easily categorized than others.

▼ Surface plasmons have been attracted extensive interests in recent decades due to the novel properties in nanometer sized dimensions. My work focused on the novel optical properties of metal nanostructures based on surface plasmons using theoretical simulation methods. In the first part, we investigated metal nanofilms and nanorods and demonstrated that extremely low scattering efficiency, high absorption efficiency and propagation with long distance could be obtained by different metal nanostructures. With a perforated silver film, we demonstrated that an extremely low scattering cross section with an efficiency of less than 1% can be achieved at tunable wavelengths with tunable widths. The resonance wavelength, width, and intensity are influenced by the shape, size and arrangement pattern of the holes, as well as the distance separating the holes along the polarization direction. The extremely low scattering could be used to obtain high absorption efficiency of a two-layer silver nanofilm. Using the discrete dipole approximation method, we achieved enhanced absorption efficiencies, which are close to 100%, at tunable wavelengths in a two-layer silver thin film. The film is composed of a 100 nm thick perforated layer facing the incident light and a 100 nm thick solid layer. Resonance wavelengths are determined by the distances between perforated holes in the first layer as well as the separation between two layers. The resonance wavelengths shift to red with increasing separation distance between two layers or the periodic distance of the hole arrays. Geometries of conical frustum shaped holes in the first layer are critical for the improved absorption efficiencies. When the hole bottom diameter equals the periodic distance and the upper diameter iv is about one-third of the bottom diameter, close to unit absorption efficiency can be obtained. We examined the electromagnetic wave propagation along a hollow silver nanorod with subwavelength dimensions. The calculations show that light may propagate along the hollow nanorod with growing intensities. The influences of the shape, dimension, and length of the rod on the resonance wavelength and the enhanced local electric field, |E|2 , along the rod were investigated. In the second part, a generalized electrodynamics model is proposed to describe the enhancement and quenching of fluorescence signal of a dye molecule placed near a metal nanoparticle (NP). Both the size of the Au NPs and quantum yield of the dye molecule are crucial in determining the emission intensity of the molecule. Changing the size of the metal NP will alter the ratio of the scattering and absorption efficiencies of the metal NP and consequently result in different enhancement or quenching effect to the dye molecule. A dye molecule with a reduced quantum yield indicates that the non-radiative channel is dominant in the decay of the excited dye molecules and the amplification of the radiative decay rate will be easier. In general, the emission intensity will be quenched when the size of metal NP is…

▼ Understanding the factors influencing mate choice is a major focus of sexual selection. Many factors are potentially involved, including age of the individual. The good genes model and the youth advantage model both make predictions about the effect of age on mate choice. Under the good genes model older mates would be the more preferable due to their proven high survivability. The “youth advantage” model, predicts that young to intermediate age males would be more advantageous as mates because of a decrease in sperm quality and the possibility of increased germ-line mutations in older animals. I examined the effects of age on behavioral and physiological factors in Diaprepes abbreviatus experimentally. Both males and females were found to be the least optimal as mates during the intermediate stage of their lives, with preferences for young and old age classes. Females had higher fertilization rates when young and fertilization steadily declined with age, consistent with the youth advantage model. Males overall had higher fertilization rate and procured matings faster when they were older, which was in accordance with the good genes model, though experience could also play a role in this result. These data here suggest that in D. abbreviatus age may play an important role in mate choice decisions.
