Fuoss, Jessica. "Bisexuality and Identity Formation." Master's thesis, University of Central Florida, 2013. http://digital.library.ucf.edu/cdm/ref/collection/ETD/id/5740.
Full textAbstract:
This study explores the identity development and psychological adjustment of bisexual individuals (n = 122) as compared to homosexual (n = 38) and heterosexual participants (n = 490). Undergraduate students recruited from psychology classes at a large metropolitan university in Florida (67% female, 64% Caucasian) took an online survey for course extra credit. Bisexual and homosexual participants scored higher in identity exploration than the heterosexual participants. Bisexual participants scored significantly higher in psychological symptom severity than heterosexual participants. The three groups were not significantly different in identity commitment nor in identity distress. Female bisexual participants scored more similar to the homosexual participants in identity exploration, while the male bisexual participants were more similar to the heterosexual participants. Among males, bisexual and homosexual participants reported greater psychological symptom severity than heterosexual participants. There were no differences between groups for female participants in regard to symptom severity. This study highlights the need for more research into the psychological correlates of bisexuality as a distinct group from homosexuality, as well as the need to focus on gender as a significant moderator of these relationships.M.S.

Nienhuis, David R. "The letter of James in the formation of the New Testament Catholic epistle collection." Thesis, University of Aberdeen, 2005. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.424918.
Full textAbstract:
This dissertation presents a reconstruction of the canonical formation of the New Testament Catholic Epistle collection. Following on similar studies of the origin of 2 Peter, it presents a new hypothesis regarding the provenance of the letter of James: the letter was written in the second century in the hopes that it might forge together a literarily coherent and theologically robust non-Pauline letter collection, a “Jerusalem Pillars” collection to balance the “Pauline”. This hypothesis, which originated out of assumptions derived from the final shape and contents of the collection itself, is first shown to be plausible on historical grounds, and then “proved” by an intertextual reading that demonstrates the redactional strategy of the second century author. Thus, chapter one offers an in-depth analysis of the formation of the Catholic Epistle collection, chapter two takes a closer look at the letter of James to establish a second century Sitz im Leben for the text, and chapter three focuses on an intertextual reading of the literary parallels between James, 1 Peter, 1 John, and the letters of Paul. Along the way, it provides a credible explanation for many of the obscurities surrounding the letter of James, namely, its late canonicity, its parallels with other apostolic letters, and its notorious lack of Christology, and further, it offers new insights into the historical formation of the New Testament canon.

Full textAbstract:
This document describes the design and analysis of the Navigation, Guidance and Control System for the KnightSat project. The purpose for the project is to test and demonstrate new technologies the Air Force would be interested in for research and development. The primary mission of KnightSat is to show how a constellation of satellites can maintain relative position with each other autonomously using the Microwave Electro Thermal (MET) thruster. The secondary mission is to use multiple satellite imagery to obtain 3 dimensional stereo photographs of observable terrain. Formation flying itself has many possible uses for future applications. Selected missions that require imaging or data collection can be more economically accomplished using smaller multiple satellites. The MET thruster is a very efficient, but low thrust alternative that can provide thrust for a very long time, hence provide the low thrust necessary to maintain the satellites at a constant separation. The challenge is to design a working control algorithm to provide the desired output data to be used to command the MET thrusters. The satellites are to maintain a constant relative distance from each other, and use the least amount of fuel possible. If one satellite runs out of fuel before the other, it would render the constellation less useful or useless. Hence, the satellites must use the same amount of fuel in order to maintain an optimal operational duration on orbit.M.S.

Khan, Majid Ali. "Coalition formation and teamwork in embodied agents." Doctoral diss., University of Central Florida, 2007. http://digital.library.ucf.edu/cdm/ref/collection/ETD/id/2711.
Full textAbstract:
Embodied agents are agents acting in the physical world, such as persons, robots, unmanned air or ground vehicles and so on. These types of agents are subject to spatio-temporal constraints, which do not exist for agents acting in a virtual environment. The movement of embodied agents is limited by obstacles and maximum velocity, while their communication is limited by the transmission range of their wireless devices. This dissertation presents contributions to the techniques of coalition formation and teamwork coordination for embodied agents. We considered embodied agents in three different settings, each of them representative of a class of practical applications. First, we study coalition formation in the one dimensional world of vehicles driving on a highway. We assume that vehicles can communicate over short distances and carry agents which can advise the driver on convoy formation decisions. We introduce techniques which allow vehicles to influence the speed of the convoys, and show that this yields convoys which have a higher utility for the participating vehicles. Second, we address the problem of coalition formation in the two dimensional world. The application we consider is a disaster response scenario. The agents are forming coalitions through a multi-issue negotiation with spatio-temporal components where the coalitions maintain a set of commitments towards participating agents. Finally, we discuss a scenario where embodied agents form coalitions to optimally address dynamic, non-deterministic, spatio-temporal tasks. The application we consider is firefighters acting in a disaster struck city.Ph.D.

DeJong, Paul. "COALITION FORMATION IN MULTI-AGENT UAV SYSTEMS." Master's thesis, University of Central Florida, 2005. http://digital.library.ucf.edu/cdm/ref/collection/ETD/id/2712.
Full textAbstract:
Coalitions are collections of agents that join together to solve a common problem that either cannot be solved individually or can be solved more efficiently as a group. Each individual agent has capabilities that can benefit the group when working together as a coalition. Typically, individual capabilities are joined together in an additive way when forming a coalition. This work will introduce a new operator that is used when combining capabilities, and suggest that the behavior of the operator is contextual, depending on the nature of the capability itself. This work considers six different capabilities of Unmanned Air Vehicles (UAV) and determines the nature of the new operator in the context of each capability as coalitions (squadrons) of UAVs are formed. Coalitions are formed using three different search algorithms, both with and without heuristics: Depth-First, Depth-First Iterative Deepening, and Genetic Algorithm (GA). The effectiveness of each algorithm is evaluated. Multi agent-based UAV simulation software was developed and used to test the ideas presented. In addition to coalition formation, the software aims to address additional multi-agent issues such as agent identity, mutability, and communication as applied to UAV systems, in a realistic simulated environment. Social potential fields provide a means of modeling a clustering attractive force at the same time as a collision-avoiding repulsive force, and are used by the simulation to maintain aircraft position relative to other UAVs.M.S.Cp.E.

Full textAbstract:
ABSTRACT Bulk metallic glasses have interesting combination of physical, chemical, mechanical, and magnetic properties which make them attractive for a variety of applications. Consequently there has been a lot of interest in understanding the structure and properties of these materials. More varied applications can be sought if one understands the reasons for glass formation and the methods to control them. The glass-forming ability (GFA) of alloys can be substantially increased by a proper selection of alloying elements and the chemical composition of the alloy. High GFA will enable in obtaining large section thickness of amorphous alloys. Ability to produce glassy alloys in larger section thicknesses enables exploitation of these advanced materials for a variety of different applications. The technique of mechanical alloying (MA) is a powerful non-equilibrium processing technique and is known to produce glassy (or amorphous) alloys in several alloy systems. Metallic amorphous alloys have been produced by MA starting from either blended elemental metal powders or pre-alloyed powders. Subsequently, these amorphous alloy powders could be consolidated to full density in the temperature range between the glass transition and crystallization temperatures, where the amorphous phase has a very low viscosity. This Dissertation focuses on identifying the various Fe-based multicomponent alloy systems that can be amorphized using the MA technique, studying the GFA of alloys with emphasis on improving it, and also on analyzing the effect of extended milling time on the constitution of the amorphous alloy powder produced at earlier times. The Dissertation contains seven chapters, where the lead chapter deals with the background, history and introduction to bulk metallic glasses. The following four chapters are the published/to be published work, where the criterion for predicting glass formation, effect of Niobium addition on glass-forming ability (GFA), lattice contraction on amorphization, effect of Carbon addition on GFA, and observation of mechanical crystallization in Fe-based systems have been discussed. The subsequent chapter briefly mentions about the consolidation of amorphous powders and presents results of hot pressing and spark plasma sintering on one of the alloy systems. The final chapter summarizes the Dissertation and suggests some prospective research work that can be taken up in future. The Dissertation emphasizes the glass-forming ability, i.e., the ease with which amorphization can occur. In this work the milling time required for amorphization was the indicator/measure of GFA. Although the ultimate aim of this work was to consolidate the Fe-based amorphous alloy powders into bulk so as to undertake mechanical characterization, however, it was first necessary to study the glass forming aspect in the different alloy systems. By doing this a stage has been reached, where different options are available with respect to amorphous phase-forming compositions and the knowledge to improve glass-forming ability via the mechanical alloying technique. This will be ultimately useful in the powder compaction process into various shapes and sizes at optimum pressure and temperature. The study on mechanical crystallization indicates, or in a way defines, a limit to the process of amorphization, and it was also demonstrated that this phenomenon is more common in occurrence than and not as restricted as it was earlier reported to be.Ph.D.

Odapalli, Nalini. "CONTROL OF STOMATAL FORMATION IN ARABIDOPSIS THALIANA INFLORESCENCE STEM." Master's thesis, University of Central Florida, 2008. http://digital.library.ucf.edu/cdm/ref/collection/ETD/id/2758.
Full textAbstract:
Stomata are cellular structures that control water loss and gas exchange through the plant epidermis. Stomata arise from special stem cells called meristemoids through a series of programmed asymmetric divisions that are controlled by cell signaling, or via multitude of regulatory pathways and intercellular communication between epidermal cells. In Arabidopsis thaliana, stomata are spaced non-randomly in the epidermis by cell-cell signaling of the receptor-like protein TOO MANY MOUTHS (TMM) as well as other proteins. Point mutation of the TMM gene prevents the development of stomata in some tissues like inflorescence stems. Investigation of tmm mutant stems showed that self-renewing stem cell-like precursors form by dividing asymmetrically but fail to form stomata. This is further supported by molecular markers of stomatal cell fate that show stomatal precursors form but do not differentiate as stomata. Therefore, TMM signaling is likely required to control expression of genes that are essential for the formation of stomata in stems. As a second approach, gene expression profiling was used to identify candidate genes involved in stomatal biogenesis. Differentially expressed genes were categorized by gene ontology and analyzed for statistically overrepresented classes to gain insight into functional processes. Comparison of stem expression data with previously published microarray data was used to narrow the list to genes involved in stomatal patterning. Mutants in these target genes have been obtained and phenotypic analysis revealed new stomatal regulators. Comparison of epidermal cells of the stem tip region from wild-type and tmm revealed that there are significantly more meristemoids formed in tmm stems compared to wild-type stems. In addition, the orientation of meristemoids formed in wild-type stems was random with respect to stem polarity and followed a spiral pattern of asymmetric divisions similar to leaves. This showed that stomatal patterning in dicots does not follow orientation in asymmetric cell division for spacing the adjacent stomata like monocots.M.S.

Gresock, Amy. "RESOURCE ACCUMULATION DYNAMICS DURING THE NEW VENTURE FORMATION PROCESS." Doctoral diss., University of Central Florida, 2010. http://digital.library.ucf.edu/cdm/ref/collection/ETD/id/4327.
Full textAbstract:
As described by the resource-based view, resource accumulation is a key concern for new ventures. Although we know that getting the right resources is a critical issue to organizations, we know far less about how fledgling firms assemble these resources over time. The purpose of this study is to examine the dynamics of resource accumulation and their effect on performance and growth during new venture formation. In particular, I examine the constructs of financial capital, human capital, and performance, and will test relationships using a sample from the Kauffman Firm Survey (KFS) that provides the necessary data to test my longitudinal proposals. I predict that that the constructs of human capital and financial capital impact performance, and that performance later impacts these constructs. I use latent curve analysis to examine the growth and decline of resource classes, and also cross-lag analysis to see how performance affects the acquisition of subsequent resources. This work has potential implications for strategy and entrepreneurship scholars alike. The document is organized as follows: Chapter 1 will serve as the introduction of the work and describe my research question and intent. Chapter 2 will serve as a relevant literature review and gives detail to theoretical perspectives guiding the study at hand. Chapter 3 presents the methodology, including information about the sample and the statistical methods utilized. Chapter 4 explains the results of the testing of hypotheses. Finally, Chapter 5 gives conclusions, limitations, and provides direction for future research.Ph.D.

Ackerman, David T. "International contracts a quantitative analysis of transnational contract formation." Honors in the Major Thesis, University of Central Florida, 2011. http://digital.library.ucf.edu/cdm/ref/collection/ETH/id/8.
Full textAbstract:
Globalization is the promise of the future, and it presents, quite literally, a world of opportunities not available in the past. International collaborations in science, research, and business now enjoy increased probabilities of success, in part, because of the advance in technology and the possibility of instantaneous communications. The convenience, simplicity and affordability of technology are helping to make the world accessible to almost everyone. With new availability of international concerns and the growth of global partnerships in all areas of interest, an increased need arises for agreements that memorialize collaborators' commitments, responsibilities and obligations. There is a corresponding concern that the agreements be enforceable across national and international lines should anything go wrong. There is no collaboration, partnership or venture that will not be touched in some way by the law. Whose law governs and how rules and regulations of different nations will be applied are of escalating concern. Empirically examining the state of international contract law is the overarching focus of my research. Adopting a research methodology involving both quantitative and qualitative techniques, I am investigating whether any consistency exists between attorneys of different practice sectors (academic, government, corporate and private) considering choice of law, enforcement of contract provisions, and the inclusion of preventative measures of international contracts. My results contribute to the future success of international collaborations of all concerns by empirically identifying the need for increased education on various dispute resolution options, as well as the effect cultural awareness has on the drafting of international contracts.ID: 030476559; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; Accepted in partial fulfillment of the requirements for honors in the major in Legal Studies.; Thesis (B.A.)--University of Central Florida, 2011.

Aminpour, Maral. "Theoretical Studies of Nanostructure Formation and Transport on Surfaces." Doctoral diss., University of Central Florida, 2013. http://digital.library.ucf.edu/cdm/ref/collection/ETD/id/6239.
Full textAbstract:
This dissertation undertakes theoretical and computational research to characterize and understand in detail atomic configurations and electronic structural properties of surfaces and interfaces at the nano-scale, with particular emphasis on identifying the factors that control atomic-scale diffusion and transport properties. The overarching goal is to outline, with examples, a predictive modeling procedure of stable structures of novel materials that, on the one hand, facilitates a better understanding of experimental results, and on the other hand, provide guidelines for future experimental work. The results of this dissertation are useful in future miniaturization of electronic devices, predicting and engineering functional novel nanostructures. A variety of theoretical and computational tools with different degrees of accuracy is used to study problems in different time and length scales. Interactions between the atoms are derived using both ab-initio methods based on Density Functional Theory (DFT), as well as semi-empirical approaches such as those embodied in the Embedded Atom Method (EAM), depending on the scale of the problem at hand. The energetics for a variety of surface phenomena (adsorption, desorption, diffusion, and reactions) are calculated using either DFT or EAM, as feasible. For simulating dynamic processes such as diffusion of ad-atoms on surfaces with dislocations the Molecular Dynamics (MD) method is applied. To calculate vibrational mode frequencies, the infinitesimal displacement method is employed. The combination of non-equilibrium Green's function (NEGF) and DFT is used to calculate electronic transport properties of molecular devices as well as interfaces and junctions.Ph.D.

The purpose of this research is to explore the processes and strategies through which members of a group or organization use their organizational identity to make salient a normatively dissonant identity. Using both the functionalist perspectives of social identity theory and the existing narrative literature on identity formation in organizations, a conceptual process model of identity formation is created that integrates the identification process with the interaction of multiple identities, including the identity as members of an organization, a normatively dissonant identity, and other salient preexisting identities such as race and gender. This research also examined part of this conceptual model empirically, using members of a national running organization for Black women, Black Girls Run!, using a mixed-methods design including interviews and surveys of participants. Distance running, as a form of physical activity, is not a normative identity for Black women in the United States. Findings from Study 1 showed that members developed a running identity that informed their running behavior. Study 2 highlighted the process through which members used their identity as members of the organization to negotiate through their dissonance and become runners using modeling strategies. Findings from this study contribute to both sport management and organizational literature by empirically demonstrating the effects of and the processes through which an organizational identity might create a pathway for marginalized groups to adapt previously dissonant identities. It highlights the importance of organizational identities in the formation of deeper connections with physical activity, which has been shown to be an essential element of health maintenance and a conduit for sustainable active behaviors.

Full textAbstract:
Business Administration/Strategic ManagementPh.D.
This dissertation includes three essays about nonprofit organizations. The first essay investigates how the availability of financial and intellectual capital in the macro-environment influences the formation of nonprofit organizations. The analysis is an extension of Weisbrod's (1975) Heterogeneity Hypothesis and Ben-Ner and van Hoomissen's (1991) "social cohesion" principle. Findings indicate financial capital and intellectual capital are important to the formation of nonprofits, but the strength and direction of their influence varies by industry. The second essay applies Stakeholder Theory to predict the influence of board members, donors, and beneficiaries on nonprofits' performance. The study incorporates 134 charities from six different industries over a five year period and finds nonprofit performance is driven by the interests of the most salient stakeholders. Furthermore, the analysis indicates nonprofit stakeholders have the ability to control the behaviors of managers; behaviors which are not necessarily aligned with mission statements. No evidence, however, suggests salient stakeholders with shared interests collaborate for mutual benefit. Stakeholder Theory is also used in the third essay to predict the moderating role stakeholders fulfill in the relationship between environmental uncertainty and nonprofits' strategic decisions. The study incorporates the same database as the second essay and discovers the influence of environmental uncertainty on nonprofits' strategic decision depends on the ability of salient stakeholders to diversify their interests. The identified effect encourages Stakeholder Theory applications adopt a dual-perspective approach to the concept of salience; such applications need to account for the salience of the stakeholder to the organization and the salience of the organization to the stakeholder.

Full textAbstract:
Le comportement de collection est un comportement specifique, distinct de la simple consommation de luxe, car il inclut les aspects de la demande pour des biens durables et des biens culturels dans l'intention de les conserver. Dans le domaine choisi (les poupées) l'absence d'intervention de l'état laisse la possibilité entière à l'analyse micro-économique de le caractériser. C'est un comportement de maximisation au cours du temps de la quantité et ou de la qualité et ou de la rareté des objets acquis et réunis, sous contrainte du budget réservé à cet effet et des informations successives disponibles. Au niveau global le processus de développement de la collection d'un domaine, qui résulte de la concurrence entre collectionneurs, se traduit par une différenciation progressive des objets et des prix, hors de tout autre calcul de rentabilité. Ce processus s' accompagne d'un développement de l'information sur les objets et sur les prix. A mesure de ce développement on observe un glissement du comportement de collection du pôle amateur au pôle spéculateur et de ce fait des stratégies d'offre face au renouvellement de la demande les conditions économiques et culturelles de la création contemporaine sont donc beaucoup plus mouvantes et incertaines que celles de la collection de départ (les objets anciens)The collector's behaviour is a specific one, distinguishable from simple luxury goods consumption since are included the interests for durable and cultural goods to be preserved in the viewspoints of demand. Inside the chosen scope (here dolls) the regulation by the sole market gives to the micro-economics analysis the whole occurence to characterize it. It is a behaviour of maximisation in the course of time of quantity and or quality and or rarity of the purchased and gathered objects, under constraint of budget intended for collecting and available successive informations. At aggregate level the process of development in a given field of collecting, which results from competition between collectors, comes amount a progressive differenciation of both objects and prices independently of all other rentability calculation. This process is attended with the development of information about objects and prices. As one goes along this development, we can observe a sliding of collector's behaviour from his amateur's pole to his speculator's one and there by of supply stra-tegies in front of the renewal of demand. Thus the economical and cul-tural conditions of creation are more uncertain than these of the starting field (antiques)

Cyberanthropology or the anthropology of cyber space/culture is an emerging subfield of cultural anthropology that deals with the varied integration of human beings and technology. This specialized area of study focuses on topics ranging from new technologies used in ethnographic research to information and communication technologies utilized by specific societal groups. Communication technology encompasses the World Wide Web, email, and online multiperson interactive spaces such as chatrooms and video games. In this work, I ethnographically investigate human social interactions in the online gaming realm of World of Warcraft. On the whole, the expanding numbers of virtual communities in existence today offer new and exciting realms for social scientists in general, and anthropologists in particular, to expand their knowledge of social interaction. During the period between August 2007 and May 2009 I "lived" with the players of WoW as a participant observer. The culmination of this research spotlights virtual group formation and dynamics from an anthropological perspective and is intended to pave the way for future research.ID: 029050327; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; Thesis (M.A.)--University of Central Florida, 2010.; Includes bibliographical references (p. 41-46).

While evidence suggests that adoptees do not differ from non-adoptees in their ability to achieve a stable sense of identity, much is still unknown about how specifically the fact of being adopted affects one's identity. The purpose of this research is to take a deeper look at the significance and meaning of being adopted to one's sense of identity through qualitative analyses of in depth interviews with adoptees. Participants were recruited from Psychology classes via the SONA system. The participants (N = 16) took part in an in-depth structured interview and completed a survey battery which included a demographic questionnaire, the Ego Identity Process Questionnaire, the Identity Distress Survey, and the Brief Symptom Index-18. Interviews were transcribed, analyzed, and coded for emerging themes using thematic analysis. The themes and their effect on adopted individuals' identity is discussed with multiple case examples.B.S.

Characterization of a material’s surface, structural and physical properties is essential to understand its chemical reactivity. Control over these properties helps tailor a material to a particular application of interest. The research presented in this dissertation focuses on characterizing a synthetic method for carbon nanomaterials and the determination of structural properties of manganese oxides that contribute to its reactivity for environmental chemistry. In particular, one research effort was focused on the tuning of synthetic parameters towards the formation of carbon nanomaterials from gaseous methane and gaseous mixtures containing various mixtures of methane, argon and hydrogen. In a second research effort, photochemical and water oxidation chemistry were performed on the manganese oxide, birnessite, to aid in the remediation of arsenic from the environment and provide more options for alternative energy catalysts, respectively. With regard to the synthesis of novel carbonaceous materials, the irradiation of gaseous methane with ultrashort pulse laser irradiation showed the production of carbon nanospheres. Products were characterized with transmission electron microscopy (TEM), scanning electron microscopy (SEM), ultraviolet (UV) Raman spectroscopy, and infrared spectroscopy. Increasing the pressure of methane from 6.7 to 133.3 kPa showed an increase in the median diameter of the spheres from ~500 nm to 85 nm. Particles with non-spherical morphologies were observed by TEM at pressures of 101.3 kPa and higher. UV Raman spectroscopy revealed that the nanospheres were composed of sp2 and sp3 hybridized carbon atoms, based on the presence of the carbon D and T peaks. A 30% hydrogen content was determined from the red shift of the G peak and the presence of a high fluorescence background. Upon extending this work to mixtures of methane, argon, and hydrogen it was found that carbon nanomaterials with varying composition and morphology could be obtained. Upon mixing methane with other gases, the yield significantly dropped, causing flow conditions to be investigated as a method to increase product yield. Raman spectra of the product resulting from the irradiation of methane and argon indicated that increasing the argon content above 97% produced nanomaterial composed of hydrogenated amorphous carbon. In a second research effort, the effect of simulated solar radiation on the oxidation of arsenite [As(III)] to arsenate [As(V)] on the layered manganese oxide, birnessite, was investigated. Experiments were conducted where birnessite suspensions, under both anoxic and oxic conditions, were irradiated with simulated solar radiation in the presence of As(III) at pH 5, 7, and 9. The oxidation of As(III) in the presence of birnessite under simulated solar light irradiation occurred at a rate that was faster than in the absence of light at pH 5. At pH 7 and 9, As(V) production was significantly less than at pH 5 and the amount of As(V) production for a given reaction time was the same under dark and light conditions. The first order rate constant (kobs) for As(III) oxidation in the presence of light and in the dark at pH 5 were determined to be 0.07 and 0.04 h−1 , respectively. The As(V) product was released into solution along with Mn(II), with the latter product resulting from the reduction of Mn(IV) and/or Mn(III) during the As(III) oxidation process. Experimental results also showed no evidence that reactive oxygen species played a role in the As(III) oxidation process. Further research on the triclinic form of birnessite focused on its activation for water oxidation. Experiments were performed by converting triclinic birnessite to hexagonal birnessite in pH 3, 5, and 7 DI water with stirring for 18 hrs. Once the conversion was complete, the solid samples were characterized with TEM and x-ray photoelectron spectroscopy (XPS). The resulting hexagonal birnessites from experiment at pH 3, 5, and 7 possessed the same particle morphology and average surface oxidation states within 1% of each other. This observation supported the claim that upon transformation, Mn(III) within the sheet of triclinic birnessite migrated into the interlayer region of the resulting hexagonal birnessite. Furthermore, the migration of Mn(III) into the interlayer and formation of the hexagonal birnessite led to an increased chemical reactivity for water oxidation compared to the bulk. Electrochemical studies showed that the overpotential for water oxidation associated with the pH 3, 5, and 7 samples was 490, 510, and 570 mV, respectively. In another set of experiments, ceric ammonium nitrate was used to test birnessite for water oxidation reactivity. These experiments showed that the pH 3 birnessite produced the most O2 of all the samples, 8.5 mmol O2/mol Mn, which was ~6 times more than hexagonal birnessite which did not undergo post-synthesis exposure to low pH conditions.

Formation of spores by Bacillus subtilis is a primitive system of differentiation that has become a paradigm for studying cell differentiation in prokaryotes. Differential gene expression commences soon after the single, asymmetric sporulation division through the activation of different RNA polymerase sigma factors, sigma F in the smaller prespore and sigma E in the larger mother cell. sigma E activation relies on an inter-cellular signaling emanating from sigma F-directed gene expression. Formation of the asymmetric division septum and compartmentalized activity of both sigma factors occur prior to chromosome partitioning. At the time of septation, only 30% of the chromosome destined to be in the prespore is actually present in that compartment and the remaining 70% is in the mother cell. Thus, both cell types contain unequal DNA content. This study focused on the effect of this genetic asymmetry on sigma F-directed gene expression, and exploited this effect in order to study aspects of sigma F to sigma E inter-compartmental signaling. Perturbed signaling resulted in the discovery of a novel twin-spore forming morphology, which was further characterized. A DNA translocase is required to translocate the remaining portion of the chromosome from the mother cell to the prespore. The replication terminus region of the chromosome was observed to be the last to enter the prespore and thus, sigma F-directed genes showed delayed and reduced expression when moved to a terminus-proximal location. The studies indicate that this positional regulation of sigma F-directed gene expression is attributed to both delayed entry and inhibition in sigma F activity at late stages of sporulation. Moreover, the next prespore-specific sigma factor, sigma G, could have a role in inhibiting sigma F. The link between sigma F and sigma E activation is the spoIIR locus, which is transcribed in the prespore from a sigma F-directed promoter soon after the formation of the asymmetric septum. Inactivation of the structural genes for sigma F or sigma E or SpoIIR results in the formation of a second septum at the opposite pole; development proceeds no further, resulting in an "abortively disporic" phenotype. The second septum is formed about 20 min after the first, and sigma E activity is required to prevent its formation. As a sigma F-directed gene, spoIIR is subject to `positional regulation': a delay in spoIIR expression caused by moving it from its origin proximal position to the chromosome terminus, is sufficient to delay sigma E activation and block spore formation, giving the abortively disporic phenotype. The effects of delaying and enhancing spoIIR expression were tested. The changes delayed sigma E activation, and many organisms formed a septum at both ends. However, both prespores in these organisms were able to develop into mature spores (twins). Extra rounds of chromosome replication occured during twin formation, so that each twin had a chromosome and the mother cell had either one or two chromosomes. This over-initiation of chromosome replication is a prerequisite for twin spore formation. Moreover, the studies showed that mother cells of twin forming organisms were longer than those containing single spores; image analysis showed that mother cell length correlates with chromosome content. In contrast to twin spore formation, during normal spore development, there is usually one copy of the chromosome in the prespore and one in the mother cell, with no growth of either compartment. Therefore, the system allowed investigating regulation of chromosome replication and growth of the mother cell. The studies showed that replication and growth are permitted because of the absence of active sigma E and of reduced levels of transcription directed by the master regulator for entrance to spore formation, Spo0A. The results indicate that the burst of Spo0A-directed expression along with activation of sigma E provide mechanisms to block replication and growth of the mother cell.

Liposomes and supported lipid bilayers (SLBs) are used as surrogates for cell membranes in a number of applications, including basic studies, in biotechnology applications, as nanoreactors, as sensors, and in environmental applications. It is crucial that the behavior of liposomes and supported lipid bilayers be understood in order that they may be better utilized in future applications. The effect of lamellarity and size on calorimetric phase transition in single component phosphatidylcholine vesicles was studied using nano-differential scanning calorimetry, dynamic light scattering and cryo-transmission electron microscopy. It was determined that the two phase transition peaks, appearing as a doublet, are attributed to mixtures of oligolamellar and unilamellar vesicles. The mechanism of supported bilayer formation of lipids on silica nanoparticles was investigated for a system of ~100 nm silica nanoparticles and zwitterionic lipids in the form of ~100 nm small unilamellar vesicles (SUVs) at high and low ionic strength, as a function of the surface area ratios of the SUVs and silica. The effect of defects, ionic strength, and size on lipid exchange and transfer on nanoparticle supported bilayers was also studied. Exchange kinetics for SUVs decreased with increasing ionic strength, a trend that was even more pronounced for SLBs. Defects on SLBs were found to occur at phase boundaries between gel and fluid phases, in bare regions of exposed silica, and during cycling due to changes in lipid area at Tm. Lastly, the behavior of styryl dyes in lipid bilayers was explored. Styrl dyes are a useful tool in a variety of biophysical application due to their properties depending on their external environment, such as a dramatic increase in their fluorescence in a hydrophobic environment as opposed to their fluorescence in the aqueous phase. Despite many applications of styrl dyes, the method of incorporation of the dyes into cell membranes, or vesicle model systems, is not resolved. Nano-differential scanning calorimetry and dynamic light scattering were used to investigate the incorporation of the styrl dyes into multilamellar (MLVs) and small unilamellar (SUVs) vesicles composed of DMPC.

This study develops a general procedure for forming a well-defined collection of documents on a research topic, which is suitable for bibliometric analysis. The procedure is applied to one research topic in Library and Information Science, Bradford's Law of Scattering. An analysis is made of the underlying concepts, viz. 'document', 'selection', 'collection comprehensiveness', 'topic', 'research topic', and 'on' and 'relevant to' a research topic. An important distinction is drawn between graphical and semantic attributes of documents, and between their modes of analysis. The central problem of the study is that, while 'topic' is a problematic semantic attribute of documents, a well-defined collection of documents requires a selection criterion formulated on unproblematic graphical attributes. The solution proposed is to let specialist A&I Services legitimate a research topic and to provide a sample of its documents; then to extract a diagnostic graphical pattern from the sample, and from this construct a criterion which can be mechanically applied to all documents. Modifications introduced into the general procedure include the iterative development of the criterion from the growing collection, and allowing a content analysis of documents to suggest diagnostic patterns in the text. The graphical selection criterion developed for the specific collection was composed of six alternative pairs of word-stems separated by at most two words in the body of the text of documents. It has an estimated precision of 96% against the background literature and retrieves 90% of all known documents which might be judged to be on the topic. The final collection consists of 1187 analytical-level and scholarly documents written in 19 languages; it is well-defined, accords with convention, and is judged to be near completion for documents more strongly on and influential in the topic. Inadequacies in the procedure and in the collection formed were examined and improvements have been suggested. For example, the mixing of semantic and graphical methods in the pattern extraction process is clarified, recall can be enhanced by the addition of several small sub-collections, and measures of topic aboutness and topic influence were installed in the collection.

This work is devoted to understanding the formation of supported lipid bilayers (SLBs) on curved surfaces as a function of lipid properties such as headgroup charge/charge density and alkyl chain length, and nanoparticle properties such as size and surface characteristics. In particular, the formation of SLBs on curved surfaces was studied by varying the size of the underlying substrate SiO2 nanoparticles with size range from 5-100 nm. Curvature-dependent shift in the phase transition behavior of these supported lipid bilayers was observed for the first time. We found that the phase transition temperature, Tm of the SLBs first decreased with decreasing the size of the underlying support, reached a minimum, and then increased when the size of the particles became comparable with the dimensions of the lipid bilayer thickness; the Tm was above that of the multilamellar vesicles (MLVs) of the same lipids. The increase in Tm indicated a stiffening of the supported bilayer, which was confirmed by Raman spectroscopic data. Moreover, Raman data showed better lipid packing and increased lateral order and trans conformation for the SLBs with increasing the curvature of the underlying support and decrease of the gauche kinks for the terminal methyl groups at the center of the bilayer. These results were consistent with a model in which the high free volume and increased outer headgroup spacing of lipids on highly curved surfaces induced interdigitation in the supported lipids. These results also support the symmetric lipid exchange studies of the SLBs as a function of the curvature, which was found to be slower on surfaces with higher curvature. Further, the effect of surface properties on the formation of SLBs was studied by changing the silanol density on the surface of SiO2 via thermal/chemical treatment and monitoring fusion of zwitterionic lipids onto silica (SiO2) nanoparticles. Our findings showed that the formation of SLBs was faster on the surfaces with lower silanol density and concomitantly less bound water compared to surfaces with higher silanol density and more bound water. Since the two SiO2 nanoparticles were similar in other respects, in particular their size and charge (ionization), as determined by zeta potential measurements, differences in electrostatic interactions between the neutral DMPC and SiO2 could not account for the difference. Therefore the slower rate of SLB formation of DMPC onto SiO2 nanoparticles with higher silanol densities and more bound water was attributed to greater hydration repulsion of the more hydrated nanoparticles. Lastly, we have investigated the effect and modulation of the surface charge of vesicles on the formation of SLBs by using different ratios of zwitterionic and cationic DMPC/DMTAP lipids. Through these studies we discovered a procedure by which assemblies of supported lipid bilayer nanoparticles, composed of DMPC/DMTAP (50/50) lipids on SiO2, can be collected and released from bilayer sacks as a function of the phase transition of these lipids. The lipids in these sacks and SLBs could be exchanged by lipids with lower Tm via lipid transfer.

Recent research supports the benefit of students’ construction of relevance through writing about the connection of content to their life. However, most such research defines relevance narrowly as utility value – perceived instrumentality of the content to the student’s career goals. Furthermore, the scope of phenomenological and conceptual dimensions that characterizes students’ perceptions of relevance remains largely unexplored in the literature. Rather, scholars have equated relevance with specific constructs such as utility, value or interest, which in turn has yielded a narrow conceptualization of relevance, usually constrained to a single construct, most commonly, utility. Whereas prior research certainly provides important insights into some of the features of relevance, it falls short of portraying the full scope of meanings that perceived relevance might take. To address this gap in the literature, this mixed-methods dissertation study explored the conceptual and phenomenological landscape of perceived relevance by employing a broad multidimensional conception of relevance to examine (a) the dimensional variability of students’ relevance constructions; and (b) the individual characteristics and the motivational and identity processes underlying differences in their constructions of relevance. The context of this study was an Institute of Educational Science (IES)-funded semester-long multi-modal intervention project that aimed to promote learning, motivation and achievement in an undergraduate introductory biology course. One module within the intervention involved students’ engagement in four relevance writing assignments, each focusing on a central biology concept in the course. The following dissertation employed data collected as part of this intervention project. This study involved coding and analyzing students’ relevance writing about two biology concepts—evolution (n = 50) and organismic diversity (n = 38)—with the purpose of characterizing dimensions underlying undergraduate students’ relevance constructions of central biology concepts and comparing these constructions across the two different biology concepts. Exploratory qualitative analysis procedures were used in the first phase of this investigation to develop an initial coding framework via intensive content analyses of students’ relevance writing products on evolution. A second phase of qualitative content analyses of students’ relevance writing about organismic diversity led to further development of the coding framework and comparative analyses of written products across the two concepts. Findings supported the dimensional variability of relevance constructions including the self-aspect connected to the content, the kind of connection made, and the type of perceived value, with some notable differences between the two biology concepts. Finally, the findings suggested that the meaningful connection engendered by the relevance construction experience originates primarily in the experience of understanding one’s self within the relation—understanding the self in relation to the relevant content; and that understanding some content in relation to a component of one’s identity may be secondary to the disclosure of the self. This dissertation explored the ways in which the relevance construction experience is a vital, dynamic process of identity formation. It is the findings from these intensive analyses that are reported in detail in this dissertation along with an in-depth discussion of the theoretical, methodological, and practical implications of this content-specific, multidimensional, identity-based conception of relevance.

This dissertation examines the formation of health policy as a cultural process in a large federal bureaucracy in the United States, namely the Department of Veterans Affairs (VA). The everyday experience of bureaucrats working in the VA is used to answer the question: why does the VA fail to meet veterans’ needs in the face of a sacred trust, available political will, and robust resources? To answer the question, this project employs ethnographic methods that draw on participant observation at the headquarters office of the VA in Washington DC, archival research, and interviews with current and former VA employees during the Obama administration. I argue that care of veterans during post-war periods are critical moments of intervention that not only improved the population health of veterans but also impacted the ways in which America conceives and responds to health challenges. I also argue that when the VA operates at its best, it is often the leading edge of health reform, setting new standards for care and effectively establishing alternative models of care. Finally, my findings show that institutional factors play an important role in the process of health policy formation in ways that contribute to new understanding about causal conceptions of health. I conclude with a framework that draws on the lessons the VA affords, for health reform and advancing just health for all.

The purpose of this dissertation is to employ simulation modeling to test theories of group formation as they pertain to hate groups: groups whose hate ideology may or may not condone violent criminal behavior. As of 2010, there were 1002 hate groups known to be active in the United States. Previous examinations of hate groups have assumed formation. This dissertation uses simulation modeling to test Hamm's (2004) criminological theory of collective hate and Weber's (1947) socio-political theory of charismatic leadership. Simulation modeling is designed to create a computer simulation that simplifies people and their interactions to mimic a real world event or phenomena. Three different experiments were tested using five models of hate group formation. These experiments test the importance of personal and societal levels of hate in group formation and the influence of charismatic leadership. These experiments also tested hypotheses regarding the number of groups that form, the speed of formation and group size. Data to test these hypotheses was collected from fifteen thousand model iterations. All three models successfully generated hate groups. Hate groups were generated at all levels of societal hate. An in-depth understanding of how hate groups form may assist in slowing the proliferation of these groups and decreasing their appeal.

Abdominal aortic aneurysm (AAA) is a major cardiovascular disease and involves enhancement of renin-angiotensin system and recruitment/activation of inflammatory factors such as matrix metalloproteases (MMP's). Caveolae has been shown to play a role in a number of different cardiovascular diseases through different mechanisms including regulation of oxidative stress, inflammation and degradation of extracellular matrix components through MMP's. In addition, endothelial cell caveolae are known to localize the Ang-II (AT1) receptor and regulate renin-angiotensin signaling. Based on these findings, we evaluated the role of caveolae in AAA formation in the murine model. Here, eight week old mice were co-infused with Ang-II and BAPN, a lysyl oxidase inhibitor, to induce AAA. We found that mice lacking the main structural protein of caveolae, caveolin-1, did not develop AAA compared to WT animals in spite of hypertensive blood pressures measured by telemetry in both groups. This finding suggests that intact Ang-II signaling remains in place in caveolin-1 knockout mice. To begin to address the underlying mechanism by which caveolae contributes to AAA, we measured the level of oxidative stress and MMP's in aneurysms. We found an increased expression of MMP-2 and MMP-9 in vessels of WT mice displaying aneurysms. This increase in expression was not observed in Cav-1 knockout mice. Furthermore, KO mice showed less oxidative stress then their WT counterparts as assessed by anti-nitrotyrosine staining. Next we examined the characteristics of early AAA formation in wild-type mice. We found caveolae associated proteins, endothelial nitric oxide synthase (eNOS) and NADPH oxidase 2 (Nox2), were upregulated in early AAA formation, particularly in the endothelium. Also, Vascular Cell Adhesion Molecule (VCAM) was upregulated in the endothelium. However, macrophage infiltration and MMP-2 activation was not observed in early AAA development. In order to elucidate the role of endothelial caveolae in the formation of AAA, we induced AAA, as previously described, in endothelial specific cav-1 knockout mice. Preliminarily findings show endothelial specific knockout mice do not form AAA as compared to their WT littermates. In conclusion, caveolae appears to play a critical role in the formation of AAA in mice via oxidative stress, and recruitment and/or activation of MMPs, specifically MMP-2 and MMP-9. Early markers of AAA formation include VCAM, NOX2, eNOS, and protein nitration. Also, preliminary results indicate that endothelial specific knockout mice do not develop AAA.

Full textAbstract:
This dissertation consists of three separate but interrelated studies examining the formation and management of tax policies. The first study uses stakeholder theory (ST) to investigate the strategic management practices of the Transport for London (TfL) during discrete stages in the adoption, implementation, and amendments of the tax policy reform known as the London Congestion Charge (LCC). Results indicate that TfL has utilized power, legitimacy, and urgency as its main policy management tactics with a significant emphasis on legitimatizing the LCC and its subsequent policy amendments. The second study draws on social exchange theory (SET) to reexamine the relationship between corporations and legislators during tax policy processes. Data for the study come from publicly available political action committee (PAC) contribution activities surrounding the Energy Independence and Security Act of 2007 (EISA07). By examining the endogeneity between legislators' voting patterns and PAC contributions by corporations, this study aims to refine empirical work on corporate political strategy, especially as it relates to crucial tax provisions embedded within an intensely debated policy proposal. Using simultaneous equations modeling (SEM), results are consistent with SET showing that an implicit and reciprocal relationship exists between corporations and legislators. This relationship affects the interdependence of how legislators vote for public policies and the amount of corporations' financial contributions to legislators. The third study investigates and aims to validate the empirical applicability of Dahan's (2005) typology of political resources in explicating the political interactions between stakeholder groups and legislators in the development of EISA07. I discuss how and why the mode of operations and various political resources employed by stakeholder groups affected the final EISA07 language concerning domestic production deduction tax credits for the oil and gas industry. Publicly available data show that both supporting and opposing stakeholder groups employ tactics consistent with Dahan's (2005) typology. However, both stakeholder groups tend to use an interactive or positive political approach to gain access and favor of legislators instead of an adversarial approach. Ultimately, the tax credits were preserved. Taken as a whole, the three studies advance the tax and public policy research literature in accounting by studying how and why relevant stakeholders affect the formation and ongoing management of public and tax policies.ID: 031001472; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; Title from PDF title page (viewed July 15, 2013).; Thesis (Ph.D.)--University of Central Florida, 2012.; Includes bibliographical references.

Cyclic stratigraphy has been recognized in the Newark Basin for many years. Each package, referred to as a Van Houten Cycle (VHC), generally has three divisions: shallow lake, deep lake, and subaerial exposure. Van Houten (1964) first proposed that Milankovitch orbital forcing was responsible for the manifestation of these ~21 kyr cycles. Although root traces have been observed in VHCs by others, no detailed paleopedological analysis has been performed that examines the relationship between individual VHCs, orbital forcing, and paleosol development. The Middle Passaic Formation of Late Triassic age is continuously exposed for over 30 meters along a railroad cut that follows Manatawny Creek near Pottstown, PA. Six VHCs were identified at this location and the upper most three were selected for detailed study due to their strong development. Three Van Houten Groups (VHGs), consisting of VHC Division 3, Division 1, and Division 2 respectively, were formed in order to group paleosol profiles (Division 3) with stratigraphically adjacent lacustrine units (Divisions 1 and 2) since the lakes directly affect the paleosurface through inundation and erosion. Petrographic analysis suggests that soils in this section only developed to the degree of Entisols or Protosols. Voids are lined with chalcedony and cored with calcite indicating diagenetic alteration. Molecular weathering ratio calculations proved unreliable due to diagenetic alteration of the strata. Magnetic susceptibility was measured on two intervals of the section, but is not well-suited to fractured, massive rock due to signal attenuation. Paleosol development is greater in instances where the overlying lake is poorly developed. Paleosols that are associated with a shallow lake or no lake likely have more time to develop than paleosols associated with deep lakes as the precipitation filling the lake would saturate the soil, hindering pedogenesis. The VHCs' ~21 kyr interval forces time to be the limiting factor for pedogenesis in this section, ending in either sedimentation or inundation. However, time is also tied to climate as it modulates from relatively moist to relatively drier within a VHC. Orbital forcing is the ultimate controlling factor in soil formation since time, climate, insolation, and precipitation are all interrelated and influenced by it. Relief is independent of orbital forcing and a possible control on soil formation within the Basin. Soils that formed distal from the bounding fault may not have been subject to inundation due to their higher elevation. Further research is needed to establish paleocatenary relationships of soil within the Newark Basin.

The process of watching a movie is a common way to be entertained in this day and age. There are multiple ways in which people can enjoy a movie ranging from the big screen at a commercial theater, on their home's television, or even in a car while driving. One outcome associated with watching a destination movie might be that the viewer will be compelled to visit or not the location portrayed in the movie. It is a primary assumption of this thesis that movies have the ability to create or change an individual's image of a destination by its portrayal within the motion picture. This study was conducted in an effort to examine this global phenomenon called movie tourism and contribute to the tourism literature. This study focused on determining the differences between pre and post measures resulting from watching a destination specific movie. The research method was a pretest-posttest experimental design conducted to a convenience sample of 247 hospitality management students enrolled in a major metropolitan university located in the southeastern portion of the United States. The research instrument was a pre and posttest questionnaire that included structured and unstructured questions in order to capture the complex destination image. The treatment between the pre and posttest was a destination specific movie. A 100% response rate was obtained from the pretest group and a 99.2% response rate from the posttest group. Results of the study revealed that: 1) certain perceived destination images were different before and after the movie; 2) level of interest in visiting the destination was not different before and after the movie; 3) destination image had a positive relationship with the level of interest in visiting the destination; and 4) certain audience characteristics had an impact on destination image and interest in visiting the location. Implications, limitations, and suggestions for future research are discussed in the final chapter.M.S.

Full textAbstract:
Liquid crystalline materials (LCMs) have gained much popularity over the past century. The thermotropic forms of these materials have been extensively studied and employed in a range of innovative applications. The lyotropic liquid crystal systems that have been studied in the past have often been formed by the organization of natural and synthetic small molecules in solutions. In this study, we use self-assembled supramolecular structures as building blocks to fabricate lyotropic liquid crystals. We investigate the self-assembly of a naturally occurring bile acid called lithocholic acid (LCA), to form supramolecular fibrous and tubular structures in basic aqueous solutions. We control the morphology of the self-assembled structures by manipulating experimental parameters in order to gain comprehensive knowledge regarding the self-assembly process. We characterize these structures with respect to their morphology i.e. their length, diameter, flexibility and shape using atomic force microscopy, optical microscopy and infrared spectroscopy. We produce lyotropic liquid crystal phases using self-assembled LCA structures through modification of physical parameters such as concentration, temperature, shear and pH. The nature of the lyotropic liquid crystal phases depends upon the morphology of the fibers and tubes. We observe that the short, rigid fibers and tubes form nematic phases while long, flexible fibers and tubes form cholesteric phases. We also study the phase transitions of the liquid crystal (LC) phases by observing their patterns using a polarizing microscope. Observations show that LC phases form in samples with LCA concentration above 0.75%w/w. Since the process of self-assembly is time-dependent, so is the formation of liquid crystal phases. We note that the optimum LCA concentration for LC phase formation is 2%-4%w/w and that the liquid crystal transition temperature is about 70[degrees]C.M.S.

Full textAbstract:
The objective of the study was to compare the trihalomethanes (THMs) produced from ferrate with hypochlorite and to determine how different the THM production would be for a given degree of disinfection (3 log reduction in Heterotrophic Plate Count (HPC)). Different water samples were collected from Lake Claire, Atlantic Ocean, and secondary effluent from an advanced wastewater treatment plant. THM formation was determined using a standard assay over 7 days at room temperature. In addition samples were tested for Total Coliform Escherichia coli (TC/E.coli), and heterotrophic bacteria using HPC by spreadplating on R2A agar. Dissolved organic carbon (DOC) was measured as well. Dosages of 2, 5, and 10 ppm of hypochlorite and ferrate were used for Lake Claire and Atlantic Ocean water, while 1, 2, and 5 ppm dosages were used for wastewater treatment effluent. Ferrate resulted in 48.3% ± 11.2% less THM produced for the same level of disinfection (i.e. approximately 3 logs reduction in HPC). Oxidation of DOC was relatively small with a 6.1 to 11.6 % decrease in DOC being observed for ferrate doses from 2 to 10 mg/L. Free chlorine oxidation of DOC was negligible.M.S.Env.E.

SociologyPh.D.
This study examines the childhood emigration, cultural and linguistic transitions and adaptation pathways of Eastern European immigrant students on an urban university campus. Although Eastern Europeans and immigrant children represent a substantial segment of the immigrant population in the U.S. they are understudied groups. After the collapse of the Soviet Union large numbers of migrants emigrated from the former Soviet Republics, but less is known about their experiences compared to other immigrant groups. Immigrant children have historically come to the U.S. since its inception but compared to the adult experience their status has been rendered ambiguous and their experiences marginalized to such an extent that they have largely been invisible in the literature. Commonly children are referred to as "children of immigrants" rather than assigned their own category of "immigrant children." While it is generally acknowledged that primary socialization of children influence their secondary socialization, the influences of child migrants' inculcation in the first culture, migration, acculturation and integration experiences with associated emotions have not been sufficiently considered. There is a general assumption in much of the immigrant scholarships that the cultural influences of the first country on child migrants are essentially negated by the acculturation process in the U.S., and this conjecture leads scholars to construct various generational categories that collapse immigrant children with the second generation native-born youth in their analysis thereby potentially skewing or obscuring critical outcome information. Since immigrant children's voices have largely been missing in the research process, through 34 in-depth interviews with Eastern European immigrant college students, we examined the extent to which the child migrants experienced the migration dislocation and incorporation as well as the possible lasting consequences in their adaptation pathways, self-identifications, social interaction, and standpoints on societal issues associated with emotional acculturation. Collectively, the Russian and Ukrainian immigrant students' narratives about their college experience indicated that they were meeting with success academically, were focused on individual goals, expressed appreciation for diversity, and were integrated into the social and professional organization on the university campus. However, most of the participants who emigrated during childhood reported that they had difficult or traumatic migration transitions in their first U.S. schools and neighborhoods, and often they recounted emotionally the memories of these profound events associated with their acculturation during the interviews. As a group, the Eastern European students expressed that both positive and negative immigration and transitional experiences, perspectives gained from the shared struggle with their parents, openness to diversity, achievement orientation, and work ethic are some of the differentiating characteristics that set them apart from their native-born American siblings, and the second-generation Russian and Ukrainian children of immigrants. Most of the Russian and Ukrainian immigrant students on campus socialized with other immigrants of diverse backgrounds, mainstream American students, least often with co-ethnics and rarely with second-generation co-ethnics or native minorities. When we conceptualize the social interaction boundary to include all immigrants, then the participants in this study may be considered "immigrant in-groupers" following in a modified form some of the findings of Grasmuck and Kim (2010) that investigated the social mixing patterns of four ethno-racial groups on the same campus. Although most of the participants had reported overall positive high school experiences, those who contended with social development issues, understanding the American culture, and the English language on the campus disproportionately represented those who had reported overall traumatic childhood integrations. As a group they embraced the ideology of meritocracy, and those who had reported traumatic childhood acculturation experiences more often adhered to the standpoint that white people were not more privileged and that equal opportunity exists for all. When we considered identity formation we found substantial complexity in the Eastern European immigrant students' self-identifications with a tendency to resist labels. Salient non ethnic (cosmopolitan/global/role) identity claims, hybrid or multi layered ethnic self-identifications that included salient non ethnic components emerged from their narratives. None of the participants identified solely as "American" but included it or referred to degree of "Americanization" as an element in their self-identification. The totality of the dominant patterns that emerged from the Eastern European immigrant students' narratives lend support for the standpoint that in research concerning outcomes for immigrant children, methodologies are warranted that take into account age at arrival, developmental stages, engendered emotions during childhood acculturation, and the standpoint of the foreign-born children. Concomitantly, the model of segmented assimilation does not theorize the potential impact of emotions on school age children who negotiate divergent peer contexts of reception without their parents. This investigation indicates that children's reaction to the nature of their acculturation may be manifested differentially when considering social psychological adjustment, adaptation, and mobility, and that the emotional legacy of childhood migration experiences ought to be considered at least equal to structural features such as governmental policies toward them, the composition of their enclaves, and labor market conditions.

Full textAbstract:
Excess production and secretion of very low-density lipoprotein (VLDL) by the liver into the circulatory system is directly related to atherosclerosis, a chronic cardiovascular disease that threatens the lives of many worldwide and continues to be a leading cause of death in the United States. The rate-limiting step in VLDL secretion is its transport from the site of biogenesis, the hepatic endoplasmic reticulum to the cis-Golgi. This step is mediated by a specialized ER- derived vesicle, the VLDL transport vesicle (VTV). Upon exit of the ER the VTV targets, fuses and delivers VLDL into the lumen of the Golgi. The targeting and fusion of the VTV with the Golgi is facilitated by specific set of soluable N-ethylmaleimide sensitive factor attachment protein receptor (SNARE) proteins that form a SNARE complex, which is required for the VTV-Golgi fusion and thus delivery to the Golgi. Data from our laboratory indicates that the formation of the SNARE complex requires cytosolic factors. Through the purification of liver cytosol, chromatographic steps, detailed mass spectrometry, immunodepletion and western blotting data it was identified that the protein necessary for SNARE complex formation is Hsc-70. Although Hsc-70's identification is significant, the role it plays in SNARE complex formation for VTV -Golgi fusion is a predicament and yet to be unraveled. In this study we performed a series of co-immunoprecipitation reactions to identify its role in SNARE-complex assembly. Using western blot data we confirmed binding of Hsc-70 with Sec22b, the v-SNARE on the VTV. Moreover, we confirmed the interaction of Hsc-70 with t-SNAREs, (syn5, rBet1 and GOS28) on the Golgi membrane. Removal of Hsc-70 from the liver cytosol resulted in significant reduction of SNARE-complex formation. Ultimately, the identification proteins involved in the process of VLDL delivery to the Golgi would offer therapeutic targets to control VLDL secretion into the blood by the liver.B.S.

Full textAbstract:
With the exception of a few studies (Leak, 2009; Fulton, 1997), psychological research on religion has not been studied from an Eriksonian identity status perspective (Erikson, 1959; Marcia, 1966). Further, Erikson's (1963) concept of identity appears to be inherently individualistic and may be conceptualized differently in Eastern/Asian cultures (Cloninger, 2008; Paranjpe, 2010). This study aims to understand the relationship of religiosity and quest to identity development across two cultures: USA and India. A total of 326 undergraduate students (mean age= 19.47, sd= 1.58) participated from two urban colleges in Mumbai, India (n= 159) and one in Orlando, USA (n= 167). All participants completed a battery of measures, including the measure of Religiosity, Quest Scale, Identity Distress Survey, and Ego Identity Process Questionnaire. Our first hypothesis was confirmed that females would have greater religiosity as compared to males amongst the Indian and USA sample. The second hypothesis was also confirmed that the USA sample would be found more among the achieved and moratorium ego identity statuses as compared to the Indian sample, who would be found more frequently in the foreclosed or diffused ego identity statuses. Although the USA sample was found to be significantly higher in identity exploration, the Indian sample was found to experience greater identity distress. Finally, our third hypothesis was partially confirmed in regard to religiosity, as it was not differentially related to identity variables in both the Indian and USA groups. However, religious quest was differentially related to the identity variables, in that it was related to identity distress in the USA sample, but not in the Indian sample.ID: 029050309; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; Thesis (M.A.)--University of Central Florida, 2010.; Includes bibliographical references (p. 77-83).

Full textAbstract:
This thesis examines the relationship among previous exposure to war and conflict, acculturation, and identity formation among adolescent refugees. It was hypothesized that US acculturation would mediate the association between exposure to war and conflict and identity development among adolescent refugees. Participants included 33 adolescent refugees (16 males and 17 females) ranging in age between 11 and 17 years (M = 14.61, SD = 1.48), who were recruited through a refugee resettlement service provider located in Orlando, Florida. Country of origin included Cuba (n = 25), Iraq (n = 4), Jordan (n =1), Haiti (n =1), Colombia (n =1), and Venezuela (n =1). Previous exposure to war and conflict was found to impact identity development; however, the proposed hypothesis in which US acculturation mediates the association between exposure to war and conflict on the one hand, and identity development on the other was not supported. Results indicated that US acculturation was not related to any of the study variables. Previous exposure to war and conflict, along with hardships caused by such experiences, were negatively correlated with identity development and positively correlated with identity distress. In addition, native acculturation was negatively correlated with identity distress, suggesting that acculturation to one's native culture may serve as a protective factor against identity distress among adolescent refugees. Implications for professional practice are discussed.B.S.

This research presents both theoretical foundation and numerical simulation work for design and analysis of a multi-agent dynamic system on the collective formation behavior patterns of grouped agents. A mass model with tunable control parameters is proposed. This model can realistically represent the aggregation pattern and the formation shape of multiple agents. Stability analysis is also provided to prove the stability of the second-order dynamic system. Several simulations will also be given according to the proposed model to show the aggregation patterns. The research on self-organizing characteristics of collective agent behaviors has a wide range of applications in nature and engineering. The formation such as a flock of birds, a school of fish, or a swarm of locusts, is the emergence of ordered state in which the moving agents can organize as formation. Design and control of the self-organizing dynamic system has implications on wireless general design of mobile sensor networks, sensor network data fusion, attitude alignment of satellite clusters and congestion control of communication networks.

Full textAbstract:
Urban BioethicsM.A.
Presumptive fertility is an ideology that leads us to treat not only pregnant women, but all female patients of reproductive age, with the presumption that they could be pregnant. This preoccupation with the possibility that a woman could be pregnant compels medical and social interventions that have adverse consequences on women’s lived experiences. It is important to pause now to examine this ideology. Despite our social realities -- there is a patient centered care movement in medical practice, American women are delaying and forgoing childbearing, abortion is safe and legal -- there is still a powerful medical and social process that subjugates womens’ bodies and lived experiences to their potential of being a mother. Fetoconsciousness, preoccupation with the fetus or hypothetical, not-yet-conceived, fetus privileges its potential embodiment over its mother’s reality. As a set of values that influence our beliefs, attitudes, and behaviors, the ideology of presumptive fertility is contextualized, critiqued, and challenged.

African American StudiesPh.D.
This dissertation analyzes and broadens the discourse regarding the impact of culture and the emergence of the social movement by focusing on some of the links between culture and social movements. Drawing upon the idea of cycle of protests this work explains how African Americans were able to materialize, communicate, and ultimately sustain separate identities under antagonistic social conditions. Critical to the understanding of this work is the role the "free space" had in shaping the identity of both African Americans and the movement which occurred as a result of their attitudes. The free space can be described as a protected area, haven, or a small-scale setting which provides activist autonomy from dominant groups where they can nurture oppositional movement identities. This study is a multifaceted account of the Black Greek-letter organizations that explains the creation of these organizations within the Black community. There are four steps or levels which were examined in order to understand the rise or the establishment of the Black organization as a means of social protest. They are: 1) mediating factors or social grievances within a community, 2) the creation of the cultural free space, 3) the framing of the organization in relation to other social movements, 4) the personal orientation or cultural affiliation (African agency) of the organizations' members. Subsequently, this study analyzed how internal conflicts, hostile social and political environments, the creation of new organizations, and the dissemination of community grievances combine to create an atmosphere which allowed the African American community to create its own separate conscious identity. By dissecting the anatomy of the social movement and the interrelated patterns that define them one will be able to recognize and ultimately predict the rise of future social movements.

Flagstaff Rim near Casper, WY preserves the most complete late Eocene section of the White River Group with over 219 m of late Eocene age sediment compared to 35 m preserved at Toadstool Park, NE. While Flagstaff Rim does not span the Eocene-Oligocene transition, it holds the earliest clues in the White River Group of a late Eocene (37-34 Ma) climatic deterioration. In this study 8 paleosols were collected, described and analyzed based on pedogenic features, mineralogy, and geochemistry, above and below dated volcanic ash beds. The lowermost paleosol is composed of smectite- rich red mudstone, with greenish gray drab haloes, and weather into hummocks. The sediments within this part of the section are the lithologic equivalent of the Peanut Peak member of Toadstool Park, NE and reflect a moist humid environment. Overlying these sediments is the lithologic equivalent of the Big Cottonwood Creek member. These sediments are comprised of smectite poor mudstones and yellow/beige sandstones, are indurated with calcium carbonate, and reflect a more arid environment. The transitional zone between the Peanut Peak and Big Cottonwood Creek lithologies corresponds with an increase in volcanism from the Great Basin, impact events, and building of ephemeral glaciers on Antarctica. The impact events and increase in volcanism, while synchronous with the transitional zone between the Peanut Peak and Big Cottonwood Creek lithologies, cannot explain the long term climatic perturbation, which persists within the White River Group. Instead, the climatic deterioration is likely explained by the building of ephemeral Antarctic ice sheets, which was compounded by the increase in volcanism and impacts. Regional variations in ä18O isotopes within the White River Group can likely explain the suggested variations in paleoclimate across the Eocene-Oligocene transition.

Streptococcus mutans is a member of the dental plaque and is the principal causative agent of dental caries. It can metabolize a wide array of sugars which results in the production of acid that causes demineralization of the tooth surface. S. mutans can also persist for extended periods of starvation, which may occur in different niches within the oral cavity. Previous studies have shown that mucin prolonged the survival of S. mutans in batch cultures and biofilms. Our laboratory has shown that the pyruvate dehydrogenase (pdh) operon is upregulated in stationary phase and is important for prolonged survival during nutrient starvation in chemically defined medium (CDM). In this study, I found that mucin enabled S. mutans to grow in a minimal chemically defined medium (MCDM) containing glucose and lacking all amino acids. A pdh mutant was found to be impaired in survival in CDM or MCDM supplemented with mucin. Additionally, I have shown that a galactose utilization mutant was impaired in survival in CDM with mucin and no exogenous glucose; galactose is the most abundant utilizable sugar residue in mucin. Mucin, supplemented in minimal medium with sucrose, also enabled S. mutans to form biofilms. Survival of the biofilms was pdh independent. Although biofilm formation was not seen in the absence of sucrose, cells did adhere to the glass coverslip; their survival was found to be pdh dependent. Using a previously constructed reporter strain, pdh expression was observed in a majority of cells in this condition. The expression of the pdh operon was also monitored in batch cultures. The starting inoculum size affected the percentage of fluorescent cells and the outcome of survival in media (CDM or MCDM) supplemented with mucin and no sugar. Greater than 50% of the stationary phase population expressed pdh in CDM with galactose. Less than 1% expressed pdh in CDM with glucose. However, galactose was unable to prolong survival of S. mutans in batch cultures in contrast to the effect of mucin. These results show that mucin may have a metabolic role in promoting long term survival of S. mutans. However it is possible that different components of mucin can be utilized in different conditions.

Full textAbstract:
A modified two-element membrane pressure vessel assembly has been used to monitor process operational changes in a full-scale reverse osmosis (RO) water treatment plant (WTP). This study evaluated the effectiveness of the assembly as an on-line monitoring device intended to detect scale formation conditions when connected to an operating RO process train. This study was implemented to support the requirements of a larger University of Central Florida (UCF) research project ongoing at the city of Sarasota's Public Works and Utilities (City) water treatment facilities located in Sarasota, Florida. During the time-frame of this study, the City was in the process of eliminating their sulfuric acid feed from the pretreatment system of their existing 4.5 million gallon per day (MGD) RO membrane process. The City was motivated to eliminate its dependence on sulfuric acid to reduce operating costs as well as reduce operation health and safety risks associated with the use of the acid as a pretreatment chemical. Because the City was concerned with secondary process impacts associated with acid elimination, additional measures were desired in order to protect the full-scale process. This thesis reports on the design, fabrication and installation of a third-stage two membrane element pressure vessel “canary” sentinel monitoring device (Canary), its effectiveness as an on-line scaling monitor during full-scale acid elimination, and presents the results of the study. The Canary sentinel device was controlled using the normalized specific flux of the two membrane elements fed by a portion of the second stage concentrate of one of the City's full-scale RO process skids. Although the Canary demonstrated the ability to detect changes in an RO process operation, scaling did not occur under the conditions evaluated in this study. An autopsy of one of the Canary elements revealed that no scaling had occurred during the acid elimination process. Therefore, the Canary was found to be useful in its function as a sentinel, even though no scaling was detected by the device after acid elimination at the City's full-scale plant had been accomplished.ID: 031001503; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; Adviser: Steven J.

The study reported here tests a model that includes several factors thought to contribute to the comprehension of static multimedia learning materials (i.e. background knowledge, working memory, attention to components as measured with eye movement measures). The model examines the effects of working memory capacity, domain specific (biology) and related domain (geoscience) background knowledge on the visual attention to static multimedia text, and their collective influence on reading comprehension. A similar model has been tested with a previous cohort of students, and has been found to have a good fit to the data (Fitzhugh, Cromley, Newcombe, Perez and Wills, 2010). The present study tests the efficacy of visual cues (signaling) on the comprehension of multimedia texts and the effects of signaling on the relationships between cognitive factors and visual attention. Analysis of Covariance indicated that signaling interacts with background knowledge. Signaling also changes the distribution of attention to varying components of the multimedia display. The path model shows that signaling alters the relationship between domain specific background knowledge (biology) and comprehension as well as that of related background knowledge (geoscience) on comprehension. The nature of the relationships indicates that the characteristics of the reading material influence the type of background knowledge that contributes to comprehension. Results are discussed in terms of their application to a classroom setting.

Full textAbstract:
Previous stepfamily research suggested that the parenting styles of biological parents and stepparents are related to children's behavioral adjustment. Scant research also provided evidence of the significance of combined parenting styles on emerging adults' behavioral adjustment. In conjunction with this literature, the scope of the current study served four purposes. First, the current study examined the degree to which parenting styles predict emerging adults' behavioral adjustment. Second, the degree to which biological parent and stepparent parenting styles predict the emerging adult-biological parent and stepparent relationships was examined. Third, the degree to which the emerging adult-biological parent and stepparent relationships predict adjustment was examined. Fourth, emerging adult-biological parent and stepparent relationships were examined as mediators in the relationship between parenting styles and emerging adults' adjustment. As part of this study, 100 emerging adults who were enrolled in a psychology course at the University of Central Florida were given a series of questionnaires regarding the variables of interest (i.e., parenting style, stepparenting style, biological parent-emerging adult relationships, stepparent-emerging adult relationships, and emerging adults' adjustment). Results of this study provided confirmation of previously held notions that both parenting styles and relationships are predictors of emerging adults' adjustment. Additionally, this study contributes new information concerning the significance of combined parenting styles and the use of parent-emerging adult relationships as a mediator between an authoritative parenting style and emerging adults' adjustment.B.S.
