description: A model has been developed to predict the yield stress of the aluminum alloy AA6111 after multi-step heat treatments which involve combinations of ambient temperature ageing and high temperature artificial ageing. The model framework follows the internal state variable framework where the two principal state variables are i) the volume fraction of clusters which form at ambient temperature and ii) the volume fraction of metastable phases which form during high temperature ageing. The evolution of the these state variables has modeled using a set of coupled differential equations. The mechanical response (the yield stress) is then formulated in terms of the state variables through an appropriate flow stress addition law. To test the model predictions a series of experiments were conducted which examined two scenarios for multi-step heat treatments. In general, good agreement was observed between the model predictions and the experimental results. However, for the case where a short thermal excursion at 250oC was applied immediately after the solution treatment, the results were not satisfactory. This can be understood in terms of the importance of the temperature dependence for the nucleation density of metastable precipitates.

On network resource allocation using alpha-stable long-range dependent traffic models
Creators: name: Lopez Guerrero, Miguel
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2004
Subjects: subject: Engineering, Electronics and Electrical.

description: Recent studies suggest that networks should be designed taking into account the long-range dependence and high-variability properties of the traffic they carry. It has been proven in the past that these two statistical properties can be properly represented using traffic models based on alpha-stable self-similar stochastic processes. Assuming this traffic modeling approach, in this dissertation we propose and evaluate some techniques for resource allocation. We propose suitable envelope processes for the levels of bandwidth demand which allows us to develop static resource allocation schemes. The proposal is based on a generalization, to the alpha-stable case, of the concept of probabilistic envelope processes, which have been previously defined for simpler models. It is shown that, with this approach, we can simply and effectively deal with much of the argued complexity encountered in alpha-stable models and develop techniques for proper dimensioning of network elements. From our analysis it is concluded that the presence of heavy tails in the distribution of the traffic process has a severe impact on the requirements of network resource. For instance, the multiplexing gain is negatively affected, which directly impacts the scale economies expected by service providers. In order to cope with these issues, dynamic resource allocation is also considered. A dynamic prediction-based resource allocation method is introduced and evaluated. It is shown that it significantly improves network utilization over static resource allocation schemes in trade for some signaling and processing overhead. Although other schemes based on prediction have been proposed, we use a novel linear prediction algorithm for symmetric fractional stable noise. This approach is intended for some traffic classes whose marginal distribution exhibits a heavy tail. The linear prediction algorithm we use was recently introduced by other researchers, but has not been studied in detail. Therefore, its performance evaluation is also carried out. In addition to this study on the prediction-based approach, a dynamic resource allocation scheme based on envelope processes is also introduced and evaluated. We conclude that when alpha-stable models are properly used and interpreted, they let us accurately represent network traffic and therefore design and analyze reliable resource allocation mechanisms.

Application of stable signal recovery to seismic interpolation
Creators: name: Hennenfent, Gilles
name: Herrmann, Felix J.
Publisher: name: Society of Exploration Geophysicists
Year: 2008

description: We propose a method for seismic data interpolation based on 1) the reformulation of the problem as a stable signal recovery problem and 2) the fact that seismic data is sparsely represented by curvelets. This method does not require information on the seismic velocities. Most importantly, this formulation potentially leads to an explicit recovery condition. We also propose a large-scale problem solver for the l1-regularization minimization involved in the recovery and successfully illustrate the performance of our algorithm on 2D synthetic and real examples.
Exploration of Ligand Effects, Substrate Effects and Reactor Effects on Macrocyclization via Ring-Closing Metathesis: A Rational Approach to Efficient Cyclization
Creators: name: Monfette, Sebastien

Subjects: subject: Chemistry, Organic.

description: Olefin metathesis is credited with having transformed the way chemists think about the manipulation of C=C bonds, the success-story of which culminated in the highest of accolades to Schrock, Grubbs and Chauvin in 2005. It is, however, difficult to reconcile the groundbreaking effect that olefin metathesis had on organic synthesis, with its limited industrial applications. Nearly twenty years following the publication of the first well-defined Ru metathesis catalyst, the RCM reaction remains largely confined to the research setting. The low turnover numbers achieved by the Grubbs catalyst is the chief limiting factor preventing industrial uptake. Clearly, more efficient catalysts and reaction methodologies are needed to render RCM industrially viable. This thesis describes various approaches towards this goal. As macrocyclic targets are highly prized in the industry, a mechanistic investigation of their formation by the Grubbs and pseudohalide catalysts was performed. This study revealed that different reaction pathways are operative for different catalysts. While the first-generation catalyst effects RCM macrocyclization by the traditional, direct path, the second-generation catalysts afford macrocyclic products through a concentration dependent oligomerization-backbiting pathway. The second approach employs structure-activity relationship to examine the effect of the anionic ligands on metathesis activity. This study unambiguously showed, for the first time, that activity correlates with the electron-donating capacity of the anionic ligands. Therefore, incorporation of less electron-withdrawing anionic ligands was sought and the synthesis of nitrogen-bound pseudohalide catalysts was carried out. Gratifyingly, the isocyanate catalyst showed remarkable reactivity at room temperature. Polymers of well-defined chain length and low polydispersity could also be obtained with this catalyst, a task that has so far eluded all of the O-bound pseudohalide catalysts. Lastly, an examination of the effect of the reactor on RCM macrocyclization efficiency was performed. An appropriate choice of continuous-flow reactor resulted in the transformation of RCM efficiency. Much faster reaction kinetics were obtained using continuous-flow reactors. Furthermore, the attainable turnover numbers are one order of magnitude higher than those using the traditional batch setup.

description: In the excess storyboard, I have placed myself centrally, though it is the participants who are reflected; there are echoes of vibrations from new media interaction, and tension in terms of the researcher versus the participants’ reflections in the mirror, as the reflection does not correspond with the person looking in the mirror (me, the researcher). Therefore, something here is not congruent, or is perplexing to the onlooker, the other. Movement is evident through the waves of emotion, engagement, and energy created by the repetition of words in the background. The words that vibrate in the background include community, location, language, and culture. By holding a mirror up to my practice, I expose the value of praxis. This mirrored image prompts the onlooker to reflect yet again on the relational component to becoming.
Curvelet-based ground roll removal

description: We have effectively identified and removed ground roll through a twostep process. The first step is to identify the major components of the ground roll through various methods including multiscale separation, directional or frequency filtering or by any other method that identifies the ground roll. Given this estimate for ground roll, the recorded signal is separated during the second step through a block-coordinate relaxation method that seeks the sparsest set for weighted curvelet coefficients of the ground roll and the sought-after reflectivity. The combination of these two methods allows us to separate out the ground roll signal while preserving the reflector information. Since our method is iterative, we have control of the separation process. We successfully tested our algorithm on a real data set with a complex ground roll and reflector structure.

description: The spread amongst humans of viral diseases such as acquired immunodeficiency syndrome (AIDS), hepatitis and severe acute respiratory syndrome (SARS) is alarming. A plant-based high fidelity production system is being developed with emphasis on producing antigens capable of being orally delivered to humans in plant packets. To test whether transgenic tobacco, carrot and rice plants can correctly process and assemble the hepatitis-B virus (HBV) core particle/antigen (HBcAg), they were transformed with a C-terminal truncated version of the HBcAg subunit coding sequence. Transgenic tobacco, carrot and rice plants processed the HBV subunits accurately indicating that these recombinant expression systems can be extended to produce other proteins at reduced costs. In the wild-type expression construct (H1); the enhanced cauliflower mosaic virus double 35S (CaMV-d35S) promoter was fused to the alfalfa mosaic virus RNA 4 (AMV-RNA4) sequence to achieve greater translation of a C-terminal truncated HBV core particle subunit. A second expression construct (H2) was plant-codon optimized to match the Arabidopsis thaliana plant genome codon preferences. A third codon-optimized expression construct (H3) had a KDEL (lysyl-aspartyl-glutamyl-leucine) encoded sequence. While a fourth expression construct (H4) included an extensin signal sequence in place of the AMV-RNA4 sequence. Western blotting analysis showed the presence of the HBcAg in transgenic tobacco, carrot and rice plants. The HBcAg levels increased from the H1 to the H4 transgenic tobacco lines. Plant codon-optimization of the HBcAg sequence and addition of the KDEL encoded sequence led to higher levels of HBcAg. The most effective modification was observed when the extensin signal sequence replaced the AMV-RNA4 translation enhancer sequence resulting in the highest observed yields of HBcAg in both the leaves and seeds of the best H4 tobacco plant. In edible plants, higher levels of HBcAg were observed in carrot roots as opposed to carrot leaves and in rice seeds as opposed to rice leaves. Further analyses via electron microscopy indicated that the HBV subunits had assembled into virus-like particles of 25--30 nm diameter in all three plant systems. Therefore, these studies may aid in the global quest to develop cheap, safe and effective vaccines.

This method consists of numerically tight linear operators and adjoints that are suitable for use in iterative algorithms. This method is also highly scalable and makes parallel processing of large seismic data sets feasible. We use this scheme to define the Parallel Windowed Fast Discrete Curvelet Transform (PWFDCT), which we apply to a seismic data interpolation algorithm. The successful performance of our parallel processing scheme and algorithm on a two-dimensional synthetic data is shown.

Publisher: name: Canadian Health Libraries Association
Year: 2008

description: In this article open access is defined, and the resources and issues of greatest relevance to the medical librarian are discussed. The economics of open access publishing is examined from the point of view of the university library. Open access resources, both journals and articles in repositories, are already significant and growing rapidly. There are close to 2300 fully open-access peer review journals listed in the Directory of Open Access Journals (DOAJ) (320 health sciences titles are included). DOAJ is adding titles at a rate of 1.5 per day. An OAIster search of resources in repositories includes more than 7.6 million items (a rough estimate of the number of articles in repositories, although not all items are full text), and this number will exceed one billion items before the end of 2007. Medical research funders, including the US National Institutes of Health, the Wellcome Trust, the UK Medical Research Council, and the Canadian Institutes of Health Research, either have implemented or are considering open access policies. This will drive greater growth in open access resources, particularly in the area of medicine. There are implications and leadership opportunities for librarians in the open access environment.
Novel Periodic Mesoporous Silicas: Synthesis, Structure and Properties
Creators: name: Czechura, Krystyna
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2010
Subjects: subject: Chemistry, Inorganic.
subject: Chemistry, Organic.

description: Hybrid organic-inorganic mesoporous silicas represent an important class of materials with a wide variety of potential applications due to their physical robustness and the chemical diversity. This work involves incorporating organic groups into mesoporous materials for the purpose of adding a useful functionality, and their characterization to gain more knowledge regarding the formation of the silicate network at different levels. A novel Gemini surfactant with a rigid organic spacer is synthesized and used to produce cubic MCM-48 silica mesophase by temperature induced phase transition. The transformation is studied under various pH and temperature conditions to understand the dynamics of the phase curvature change (Chapter 3). Further, to investigate the effect of high density of surface grafted amino groups, post-synthesis modification of grafted 3-halopropylsilane with amine is employed to generate long chain amines on the surface of pore-expanded MCM-41 silica (PE-MCM-41). The performance of such materials for CO2 adsorption is discussed in relation to the structural differences caused by the choice of the synthetic method (Chapter 4). For the first time, a bridged photoresponsive arylorganosilane 1,4'-bis(triethoxysilyl)azobenzene is used as a precursor for the synthesis of pure azobenzene-bridged organosilica. Reversible photoisomerization of the azobenzene moieties integrated in mesoporous organosilica network is demonstrated indicating that the organosilica remains flexible enough to undergo such contractions under UV irradiation (Chapter 5). Lastly, periodic mesoporous organosilica is synthesized using two silsesquioxane precursors containing bulky dimethylphenyl and a smaller ethylene spacer, and the 2D 29Si-1H heteronuclear correlation technique is employed to specifically address the issue of structural homogeneity in the bifunctional PMO (Chapter 6).
A mathematical argument for the generalisation of classical electrodynamics
Creators: name: Kirsten, Johan
Publisher: name: figshare
Year: 2012
Subjects: Applied Physics

description: Classical electrodynamics assumes the Lorenz gauge condition. There exists a generalisation of classical electrodynamics that does not make this assumption. This paper will put forth a mathematical argument that supports this generalisation by proving, using classical electrodynamics, that the Lorenz gauge condition cannot be assumed. Instead it is shown that electrodynamics should include a scalar field that is created by current density in the direction of the current density. There also exists experimental evidence that supports this generalisation, which has been called into question. This paper will give an argument as to why this experimental evidence should be accepted as proof of the validity of the generalisation of classical electrodynamics.
Categorical models of computation: Partially traced categories and presheaf models of quantum computation
Creators: name: Malherbe, Octavio
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2010
Subjects: subject: Mathematics.

description: This dissertation has two main parts. The first part deals with questions relating to Haghverdi and Scott's notion of partially traced categories. The main result is a representation theorem for such categories: we prove that every partially traced category can be faithfully embedded in a totally traced category. Also conversely, every monoidal subcategory of a totally traced category is partially traced, so this characterizes the partially traced categories completely. The main technique we use is based on Freyd's paracategories, along with a partial version of Joyal, Street, and Verity's Int construction. Along the way, we discuss some new examples of partially traced categories, mostly arising in the context of quantum computation. The second part deals with the construction of categorical models of higher-order quantum computation. We construct a concrete semantic model of Selinger and Valiron's quantum lambda calculus, which has been an open problem until now. We do this by considering presheaf categories over appropriate base categories arising from first-order quantum computation. The main technical ingredients are Day's convolution theory and Kelly and Freyd's notion of continuity of functors. We first give an abstract description of the properties required of the base categories for the model construction to work; then exhibit a specific example of base categories satisfying these properties.

description: Single cell proteins (SCP) and oils (SCO) are promising alternatives for replacing conventional feed ingredients in animal and aquaculture fish feeds. The production costs of SCP and SCO need to be reduced by using inexpensive substrates (production by-products) suitable for cultivation of protein and oil producing microorganisms. This article reviews the availability of milk processing by-product – whey in Latvia, in 2019. Additionally, a simple production plant location optimization model is proposed, where no prior knowledge of location optimization or experience with dedicated software is required from the user. The case study demonstrated that the model is valid, and it can be used as a simple tool for resource acquisition from multiple sources to single production plant.

Creators: name: Васил Пенчев

Subjects: Quantum Mechanics

description: “Negative probability” in practice. Quantum Communication: Very small phase space regions turn out to be thermodynamically analogical to those of superconductors. Macro-bodies or signals might exist in coherent or entangled state. Such physical objects having unusual properties could be the basis of quantum communication channels or even normal physical ones … Questions and a few answers about negative probability: Why does it appear in quantum mechanics? It appears in phase-space formulated quantum mechanics; next, in quantum correlations … and for wave-particle dualism. Its meaning:- mathematically: a ratio of two measures (of sets), which are not collinear; physically: the ratio of the measurements of two physical quantities, which are not simultaneously measurable. The main innovation is in the mapping between phase and Hilbert space, since both are sums. Phase space is a sum of cells, and Hilbert space is a sum of qubits. The mapping is reduced to the mapping of a cell into a qubit and vice versa. Negative probability helps quantum mechanics to be represented quasi-statistically by quasi-probabilistic distributions. Pure states of negative probability cannot exist, but they, where the conditions for their expression exists, decrease the sum probability of the integrally positive regions of the distributions. They reflect the immediate interaction (interference) of probabilities common in quantum mechanics
Novel conjugation strategies for hybrid biomacromolecules

Subjects: subject: Chemistry, Biochemistry.

description: The work presented in this thesis describes the development of novel methodology for the preparation of macromolecular conjugates using proteins and dendrimers as scaffolds. This methodology is based on the discovery that chemical modification of proteins can be achieved in vacuo, in the absence of solvents, viz., water. The results obtained represent the first attempts to use this methodology to achieve protein modifications that are otherwise difficult or impossible under aqueous conditions. While the inspiration for this research stemmed from practical objectives, much of the work undertaken developed into a proof of principle, not by design, but due to the fact that there is no precedence or established theoretical base for the in vacuo chemical modification of proteins. Initially, the scope of the project involved the design and development of a novel detoxication construct for an artificial liver consisting of an enzyme coupled to lipophilic poly(propyleneimine) dendrimers as partitioning agents for the clearing of hydrophobic compounds from aqueous solution. While the lipophilic dendrimers proved to be feasible partitioning agents when tested with some drugs in aqueous solution, attempts to attach a model enzyme to the construct by established methods in solution met with limited success. The search for better, more efficient methods of tethering, immobilizing and cross-linking enzymes lead to the investigation of alternative conjugation methods. p-Nitrophenylchloroformate is a common activating reagent used in organic synthesis and has been used to activate chemical modifiers for proteins. However, this reagent has not been used for direct chemical modification of proteins because of its insolubility in water. The results obtained show that this reagent, when used with the in vacuo procedure, can activate and cross-link proteins through chemical modification of protein carboxyl groups. In the course of these studies it was observed that a covalent dimer was present in ribonuclease A heated in the absence of reagent. This observation lead to an investigation which demonstrated that proton transfers between interacting carboxylate and ammonium groups in vacuo results in the formation of amide bonds. Compared to solution methods, the in vacuo methods developed are experimentally simple, and may also be carried out without the use of reactive chemical reagents. Glycation of protein amino groups with reducing monosaccharides can readily be achieved by the formation of stable ketoamine derivatives using the in vacuo methodology. (Abstract shortened by UMI.)

description: Optical electric field sensors have been used for the measurement of high-voltages found in power substations. Typical sensors are based on electro-optic crystals and hence require the coupling of light into and out of the crystals from optical fibers. This coupling is difficult and costly. The objective of the work presented here is the design and implementation of an optical electric field sensor that uses an entirely fiber-based sensor-head. The sensor-head is comprised of a D-shaped optical fiber with its flat side coated with liquid crystals. D-fibers allow easy access to the evanescent optical field and replacement of part of the cladding with an external medium allows for modulation of this optical field. We are investigating the use of chiral Smectic A liquid crystals, which respond linearly to electric fields through the electroclinic effect. The propagation characteristics of the D-fiber for various distances between the fiber core edge and flat and for various refractive indices of the external medium are theoretically investigated and experimentally verified. Preliminary experimental results for a prototype electric field sensor are presented. The sensor responds in a linear fashion to an applied electric field.

Sustained interactivity as a predictor of the use of a well-developed program innovation

Subjects: subject: Education, Administration.

description: Huberman (1989) identified a concept called sustained interactivity as a powerful predictor of use of innovations. It is defined as multiple exchanges between researchers and potential users of that research at different phases of a study. The sustained interactivity construct implies that linkages between disseminators of knowledge and potential users of it are strengthened as they increase in frequency and intensity. This study applied Huberman's (1990) model of the sustained interactivity construct within the implementation context of an existing, well-developed North American educational program called Project WILD. The model was enriched by the inclusion of other research findings (e.g., Cousins & Leithwood, 1993). A single-group, retrospective design was used to carry out an explanatory study. Data were collected by administering a common survey questionnaire to a purposive sample of classroom teachers (N = 2,000) across North America who are potential users of Project WILD, which resulted in an achieved sample (n = 515) of eligible respondents. A conceptual framework derived from the literature guided the study wherein use was investigated from two perspectives, under varying conditions of sustained interactivity that ranged in levels from high to low to an absence of contact among the users and the disseminators of the innovation. The first perspective was the use of the program innovation. The second was process use, which relates to how users are affected because of their participation in, or proximity to, the innovation. Hierarchical linear regression enabled an examination of the impact on use of (1) sustained interactivity as a global measure, and (2) of nine indicators that were employed in this study to reflect it. Five covariates were used to obtain more precise estimates of sustained interactivity effects. It was found, and concluded, that use varies as a direct function of sustained interactivity. Of its nine indicators, three were found, and concluded, to be especially potent: Benefits of sustained interactivity was found to be a significant predictor of process use and conceptual use of the innovation; social processing about it among teachers and their involvement and engagement in it emerged as important predictors of putting the innovation into practice more fully. Social processing was also found to be a predictor of process use. A version of the teachers' questionnaire was administered to a sample of disseminators (N = 23) of the innovation across North America. (Abstract shortened by UMI.)

description: A new 3D ultrasound-based patient positioning system for target localisation during radiotherapy is described. Our system incorporates the use of tracked 3D ultrasound scans of the target anatomy acquired using a dedicated 3D ultrasound probe during both the simulation and treatment sessions, fully automatic 3D ultrasound-toultrasound registration, and OPTOTRAK IRLEDs for registering simulation CT to ultrasound data. The accuracy of the entire radiotherapy treatment process resulting from the use of our system, from simulation to the delivery of radiation, has been validated on a phantom. The overall positioning error is less than 5mm, which includes errors from estimation of the irradiated region location in the phantom.

Premature termination from adult psychotherapy: Can therapy-specific and contextual factors help predict who will drop out?

description: This longitudinal study was designed to refine the search for reliable predictors of premature termination from adult psychotherapy by examining therapy-specific and contextual factors that may predict clients' decisions to leave treatment early. These variables included client's stage of change prior to treatment, client's level of self-determination or motivation for therapy, client and therapist expectations and any discrepancies between them, the therapeutic alliance, and practical barriers to treatment participation. To facilitate comparison with previous research, premature termination was operationalized in two manners, duration of treatment and type of termination decision (unilateral versus mutual agreement with the therapist), although type of termination decision was considered a better measure of premature termination. These variables were examined with self-report data from 107 client/therapist dyads at a community mental health clinic. Data were collected prospectively and retrospectively from both client and therapist perspectives before therapy began, after the third treatment session, and after therapy ended. Logistic regression analyses showed that barriers to treatment participation, measured at the end of therapy, and working alliance, measured after the third treatment session, predicted type of termination from the client perspective, and barriers predicted type of termination from the therapist's perspective. The therapist's perception of barriers to treatment added incremental predictive value to that of the client's. The client's perspective on barriers to treatment also enhanced the predictive value of the therapist's perception of barriers. The discrepancy between client and therapist expectations for therapy duration did not predict the nature of the termination decision. When a client had a low self-determination index score, or was non self-determined, but had expectations of longer therapy, he or she tended to make a unilateral decision to end therapy. If a client, who perceived a poor working alliance, was not far along in the stage of change process (e.g., more contemplative than active), s/he was more likely to make a unilateral decision to end therapy. The strengths and limitations of the study and implication of these results for future research and clinical application are discussed. The findings support the overall contention of this study that it is therapy-specific and contextual factors, and not client or therapist factors alone, that predict the likelihood of premature termination.

description: The talk provides advice on how to approach doing statistical analyses within the context of a thesis. Several big picture frameworks will be discussed through which we can try to understand the role and purpose of data analysis. In particular the importance of making reasoned decisions, telling an interesting story, becoming a scientist-practitioner, and the role of data analysis in improving democracy will be discussed. The importance of several contemporary issues relevant to anyone doing data analysis in psychology will also be discussed including, Confidence Intervals, Effect Size, Null Hypothesis Significance Testing, Power Analysis, Accuracy in Parameter Estimation and Meta Analytic thinking. The talk aims to provide some concrete strategies for assisting in the analysis of your thesis data, as well as showing why analysing your thesis data can be a motivating and passionate experience.

description: Clover is an experiment which aims to detect the signature of gravitational waves from inflation by measuring the B-mode polarization of the cosmic microwave background. Clover consists of three telescopes operating at 97, 150, and 220 GHz. The 97-GHz telescope has 160 horns in its focal plane while the 150 and 220-GHz telescopes have 256 horns each. The horns are arranged in a hexagonal array and feed a polarimeter which uses finline-coupled TES bolometers as detectors. To detect the two polarizations the 97-GHz telescope has 320 detectors while the 150 and 220-GHz telescopes have 512 detectors each. To achieve the required NEPs the detectors are cooled to 100 mK for the 97 and 150-GHz polarimeters and 230 mK for the 220-GHz polarimeter. Each detector is fabricated as a single chip to guarantee fully functioning focal planes. The detectors are contained in linear modules made of copper which form split-block waveguides. The detector modules contain 16 or 20 detectors each for compatibility with the hexagonal arrays of horns in the telescopes' focal planes. Each detector module contains a time-division SQUID multiplexer to read out the detectors. Further amplification of the multiplexed signals is provided by SQUID series arrays. The first prototype detectors for Clover operate with a bath temperature of 230 mK and are used to validate the detector design as well as the polarimeter technology. We describe the design of the Clover detectors, detector blocks, and readout, and give an update on the detector development. Copyright 2006 Society of Photo-Optical Instrumentation Engineers.

description: In the age of mass information, globalization, and peer-to-peer social networks, the traditional markers of identity and elective affinities, particularly those of religion and nationalism, are shifting in relation to contemporary trends. The field of Religious Studies has been influenced by a series of ‘post’s: postsecular, postmodern, postcolonial, and post 9/11. The rise of revolutionary religious movements internationally is a hallmark characteristic of the postsecular age. Participants in these movements are variously characterized as religious dissidents, militant secularists, neo-fascist nationalists, and terrorists. However, according to the dialogues within these communities, participants do not think of themselves in these terms. The dualizing labels of ‘religious’ and ‘secular’ do not lend meaning to these contemporary identities. This thesis addresses the question: How do traditional and contemporary theories in the field of Religious Studies evaluate contemporary religious nationalist movements, and how do their analyses compare to how members of the groups in question perceive themselves? To answer this question, this dissertation examines and contrasts four key case studies: the Native Faith Movement and Femen in Ukraine, and the Gezi Park protesters and the Gülen Movement in Turkey. By analyzing group activities through the fora of the curated digital presences of group leaders and members, this research investigates emerging elective affinities and markers of identity which transcend the religious/secular binary. Contemporary theory from the field of Critical Religion and feminist theology transcending the religious/secular binary will be applied to these case studies in order to gain a deeper understanding of the shifting relationships between religion, protest and the nation.
