Writing and rewriting feminist and irreverent texts : Poetry, narrative, pedagogy and life
Creators: name: Norman, Renee
Publisher: name: University of British Columbia
Year: 2009

description: This narrative thesis presents a collection of creative writing that autobiographically traces a story about coming to writing and transforming through writing. The creative writing is structured so that the themes are re-worked through additional sections of writing which contribute to the research. This research approach is adapted from the two-step process of narrative interpretive inquiry described by curricular theorist Dr. Ted Aoki. Such a process builds upon a phenomenological revisitation of lived experience with a post-structural consideration of the possible meanings within experience as it is written and re-written. The inquiry within this thesis is also framed in feminist thought, interweaving the writings of French feminists Helene Cixous and Julia Kristeva, British writer/feminist Virginia Woolf, and several North American feminist writers and theorists. Such thought advocates autobiographical and creative life writing and journalizing. Further, the resultant, storied texts contribute to our knowledge of the particularities of feminine experience. This knowledge shifts and changes as the signs and signifiers of the texts are destabilized in the intertextual relationship between writers, texts and readers. Through the powerful process of writing and storying, the writer comes to examine and understand the selves while simultaneously writing these selves into text. Such learning parallels the recursive nature of writing in a back and forth movement that emphasizes how we learn to write as we write to learn. Such learning becomes the means to reflect upon the significance of the pedagogical selves, bringing a more "thoughtful and tactful praxis" (van Manen 1990, 124-133) into our teaching, as well as a fuller understanding of the writing and reflecting process for students. The approach of this thesis consists not only of writing in various genres, but selecting them and shaping them into a text. The thesis identifies and discusses an egocentric story that specifies how a woman writer and teacher became through writing, and how this becoming begins to transform to a subjectivity which is decentered in relationship to other subjects and other texts. The pedagogical implications of this story for curriculum practice are situated within the empowering teaching strategies which encourage the writing and which serve as a model for teaching practice.

description: We consider N =1 supersymmetric QCD with the gauge group U(N) and N_f=N quark flavors. To get rid of flat directions we add a meson superfield. The theory has no adjoint fields and, therefore, no 't Hooft-Polyakov monopoles in the quasiclassical limit. We observe a non-Abelian Meissner effect: condensation of color charges (squarks) gives rise to confined monopoles. The very fact of their existence in N =1 supersymmetric QCD without adjoint scalars was not known previously. Our analysis is analytic and is based on the fact that the N =1 theory under consideration can be obtained starting from N =2 SQCD in which the 't Hooft-Polyakov monopoles do exist, through a certain limiting procedure allowing us to track the status of these monopoles at various stages. Monopoles are confined by BPS non-Abelian strings (flux tubes). Dynamics of string orientational zero modes are described by supersymmetric CP(N-1) sigma model on the string world sheet. If a dual of N =1 SQCD with the gauge group U(N) and N_f=N quark flavors could be identified, in this dual theory our demonstration would be equivalent to the proof of the non-Abelian dual Meissner effect.

description: We describe the thermodynamic state of a highly confined single-phase and single-component fluid in a slit pore using Hill's thermodynamics of small systems. This theory was more recently named nanothermodynamics. We start by constructing an ensemble of slit pores for controlled temperature, volume, surface area, and chemical potential. We present the integral and differential properties according to Hill, and use them to define the disjoining pressure. We identify all thermodynamic pressures by their mechanical counterparts in a consistent manner, and investigate the identification by molecular dynamics simulations. We define and compute the disjoining pressure, and show that it contains the standard definition. We compute the entropy and energy densities, and find in agreement with the literature, that the forces at the wall are of an energetic, not entropic nature. The subdivision potential is zero for this slit pore with large walls, but unequal to zero for related sets of control variables. We show how Hill's method can be used to find new Maxwell relations of a confined fluid, in addition to a scaling relation, which applies when the walls are separated far enough. By this expansion of nanothermodynamics, we set the stage for further developments of the thermodynamics of confined fluids, a field that is central in nanotechnology.

description: We analyse the environment of low redshift, z < 0.2, SDSS quasars using the spectral and photometric information of galaxies from the Sloan Digital Sky Survey Third Data Release (SDSS-DR3). We compare quasar neighbourhoods with field and high density environments through an analysis on samples of typical galaxies and groups. We compute the surrounding surface number density of galaxies finding that quasar environments systematically avoid high density regions. Their mean environments correspond to galaxy density enhancements similar to those of typical galaxies. We have also explored several galaxy properties in these environments, such as spectral types, specific star formation rates, concentration indexes, colours and active nuclei activity. We conclude that low redshift quasar neighbourhoods (r_p < 1 Mpc h^-1, Delta V < 500 km/s) are populated by bluer and more intense star forming galaxies of disk-type morphology than galaxies in groups and in the field. Although star formation activity is thought to be significantly triggered by interactions, we find that quasar fueling may not require the presence of a close companion galaxy (r_p < 100 kpc h^-1, Delta V< 350 km/s). As a test of the unified AGN model, we have performed a similar analysis to the neighbours of a sample of active galaxies. The results indicate that these neighbourhoods are comparable to those of quasars giving further support to this unified scenario.

description: The negative ion of lanthanum, La$^-$, has one of the richest bound state spectra observed for an atomic negative ion and has been proposed as a promising candidate for laser-cooling applications. In the present experiments, La$^-$ was investigated using tunable infrared photodetachment spectroscopy. The relative signal for neutral atom production was measured with a crossed ion-beam--laser-beam apparatus over the photon energy range 590 - 920 meV (2100 - 1350 nm) to probe the continuum region above the La neutral atom ground state. Eleven prominent peaks were observed in the La$^-$ photodetachment cross section due to resonant excitation of quasibound transient negative ion states in the continuum which subsequently autodetach. In addition, thresholds were observed for photodetachment from several bound states of La$^-$ to both ground and excited states of La. The present results provide information on the excited state structure and dynamics of La$^-$ that depend crucially on multielectron correlation effects.

Locating the gamma-ray emission region in the brightest Fermi-LAT Flat Spectrum Radio Quasars

description: We present a temporal and spectral analysis of the gamma-ray flux from nine of the brightest flat spectrum radio quasars (FSRQs) detected with the Fermi Large Area Telescope (LAT) during its first eight years of operation, with the aim of constraining the location of the emission region. Using the increased photon statistics provided from the two brightest flares of each source, we find evidence of sub-hour variability from B2 1520+31, PKS 1502+106 and PKS 1424-41, with the remaining sources showing variability on timescales of a few hours. These indicate gamma-ray emission from extremely compact regions in the jet, potentially compatible with emission from within the broad line region (BLR). The flare spectra show evidence of a spectral cut-off in 7 of the 18 flares studied, further supporting the argument for BLR emission in these sources. An investigation into the energy dependence of cooling timescales finds evidence for both BLR origin and emission from within the molecular torus (MT). However, Monte Carlo simulations show that the very high energy (VHE) emission from all sources except 3C 279, 3C 454.3 and 4C 21.35 is incompatible with a BLR origin. The combined findings of all the approaches used suggest that the gamma-ray emission in the brightest FSRQs originates in multiple compact emission regions throughout the jet, within both the BLR and the MT.

description: The aim of the present thesis is the study of control techniques that are based on geometric ideas and Lie group decomposition and are applied on quantum systems for quantum state engineering. In the first chapters we present the historical background of quantum computing, its progress and the first, but important quantum algorithms, we introduce definitions and mathematical concepts, necessary for the interpretation of quantum operators, as Lie groups and unitary operators. Furthermore, fundamentals of quantum mechanics and quantum computation are presented. We introduce the quantum state as a vector, the representation of qubits and the Bloch sphere. Moreover, the Euler decomposition is shown. We study the steering from an initial state to another state, using rotations of two axes and we include two algorithms; one for computing of generalized Euler angles and another for decomposing an operator to a sequence of rotations around two axes. We also show a control scheme that is based on hyperspherical coordinates. We present an algorithm to calculate the hyperspherical coordinates of a vector, a second one that gives the sequence of rotations from an initial to a final state using those coordinates and finally a generalisation for quantum operators.
Intrinsic Mechanism for Magneto-Thermal Conductivity Oscillations in Spin-Orbit-Coupled Nodal Superconductors

description: We describe a mechanism by which the longitudinal thermal conductivity $κ_{xx}$, measured in an in-plane magnetic field, oscillates as a function of field angle in layered nodal superconductors. These oscillations occur when the spin-orbit splitting at the nodes is larger than the nodal scattering rate, and are complementary to vortex-induced oscillations identified previously. In sufficiently anisotropic materials, the spin-orbit mechanism may be dominant. As a particular application, we focus on the cuprate high-temperature superconductor YBa$_2$Cu$_3$O$_{6+x}$. This material belongs to the class of Rashba bilayers, in which individual CuO$_2$ layers lack inversion symmetry although the crystal itself is globally centrosymmetric. We show that spin-orbit coupling endows $κ_{xx}/T$ with a characteristic dependence on magnetic field angle that should be easily detected experimentally, and argue that for underdoped samples the spin-orbit contribution is larger than the vortex contribution. A key advantage of the magneto-thermal conductivity is that it is a bulk probe of spin-orbit physics, and therefore not sensitive to inversion breaking at surfaces.

description: With the use of deep learning in many areas, how to improve this technology or how to develop the structure used more effectively and in a shorter time is an issue that is of interest to many people working in this field. Many studies are carried out on this subject, it is aimed to reduce the duration of the operation and the processing power required, except to obtain the best result with the changes made in the variables, functions and data in the models used. In this study, in the leaf classification made using Mendeley data set consisting of leaf images with a fixed background, all other variables such as layer number, iteration, number of layers in the model and pooling process were kept constant, except for the filter dimensions of the convolution layers in the determined model. Convolution layers in 3 different filter sizes and in addition to this, many results obtained in 2 different structures, increasing and decreasing, and 3 different image sizes were examined. In the literature, it is seen that different uses of pooling layers, changes due to increase or decrease in the number of layers, the difference in the size of the data used, and the results of many functions used with different parameters are evaluated. In the leaf classification of the determined data set with CNN, the change in the filter size of the convolution layer together with the change in different filter combinations and in different sized images was focused. Using the data set and data reproduction methods, it was aimed to make the differences in filter sizes and image sizes more distinct. Using the fixed number of iterations, model and data set, the effect of different filter sizes has been observed.

description: Black widow and redback systems are compact binaries in which a millisecond pulsar heats and may even ablate its low-mass companion by its intense wind of relativistic particles and radiation. In such systems, an intrabinary shock can form as a site of particle acceleration and associated non-thermal emission. We model the X-ray and gamma-ray synchrotron and inverse-Compton spectral components for select spider binaries, including diffusion, convection and radiative energy losses in an axially-symmetric, steady-state approach. Our new multi-zone code simultaneously yields energy-dependent light curves and orbital phase-resolved spectra. Using parameter studies and matching the observed X-ray spectra and light curves, and Fermi Large Area Telescope spectra where available, with a synchrotron component, we can constrain certain model parameters. For PSR J1723--2837 these are notably the magnetic field and bulk flow speed of plasma moving along the shock tangent, the shock acceleration efficiency, and the multiplicity and spectrum of pairs accelerated by the pulsar. This affords a more robust prediction of the expected high-energy and very-high-energy gamma-ray flux. We find that nearby pulsars with hot or flaring companions may be promising targets for the future Cherenkov Telescope Array. Moreover, many spiders are likely to be of significant interest to future MeV-band missions such as AMEGO and e-ASTROGAM.

description: Conventional nucleon-nucleon potentials with strong short-range repulsion require contributions from high-momentum wave function components even for low-energy observables such as the deuteron binding energy. This can lead to the misconception that reproducing high-energy phase shifts is important for such observables. Interactions derived via the similarity renormalization group decouple high-energy and low-energy physics while preserving the phase shifts from the starting potential. They are used to show that high-momentum components (and high-energy phase shifts) can be set to zero when using low-momentum interactions, without losing information relevant for low-energy observables.

description: Puckered honeycomb Sb monolayer, the structural analog of black phosphorene, has been recently successfully grown by means of molecular beam epitaxy. However, little is known to date about the growth mechanism for such puckered honeycomb monolayer. In this study, by using scanning tunneling microscopy in combination with first-principles density functional theory calculations, we unveil that the puckered honeycomb Sb monolayer takes a kinetics-limited two-step growth mode. As the coverage of Sb increases, the Sb atoms firstly form the distorted hexagonal lattice as the half layer, and then the distorted hexagonal half-layer transforms into the puckered honeycomb lattice as the full layer. These results provide the atomic-scale insight in understanding the growth mechanism of puckered honeycomb monolayer, and can be instructive to the direct growth of other monolayers with the same structure.

description: We studied the accretion disc structure in the doubly imaged lensed quasar SDSS J1339+1310 using $r$-band light curves and UV-visible to near-IR (NIR) spectra from the first 11 observational seasons after its discovery. The 2009$-$2019 light curves displayed pronounced microlensing variations on different timescales, and this microlensing signal permitted us to constrain the half-light radius of the 1930 Å continuum-emitting region. Assuming an accretion disc with an axis inclined at 60 deg to the line of sight, we obtained log$_{10}$($r_{1/2}$/cm) = 15.4$^{+0.3}_{-0.4}$. We also estimated the central black hole mass from spectroscopic data. The width of the Civ, Mgii, and H$β$ emission lines, and the continuum luminosity at 1350, 3000, and 5100 Å, led to log$_{10}$($M_{BH}$/M$_{\odot}$) = 8.6 $\pm$ 0.4. Thus, hot gas responsible for the 1930 Å continuum emission is likely orbiting a 4.0 $\times$ 10$^8$ M$_{\odot}$ black hole at an $r_{1/2}$ of only a few tens of Schwarzschild radii.

description: Following the path of minimalism in alternative theories of gravity, we construct the "Minimal Theory of Bigravity" (MTBG), a theory of two interacting spin-2 fields that propagates only four local degrees of freedom instead of the usual seven ones and that allows for the same homogeneous and isotropic cosmological solutions as in Hassan-Rosen bigravity (HRBG). Starting from a precursor theory that propagates six local degrees of freedom, we carefully choose additional constraints to eliminate two of them to construct the theory. Investigating the cosmology of MTBG, we find that it accommodates two different branches of homogeneous and isotropic background solutions, equivalent on-shell to the two branches that are present in HRBG. Those branches in MTBG differ however from the HRBG ones at the perturbative level, are both perfectly healthy and do not exhibit strong coupling issues nor ghost instabilities. In the so-called self-accelerating branch, characterized by the presence of an effective cosmological constant, the scalar and vector sectors are the same as in General Relativity (GR). In the so-called normal branch, the scalar sector exhibits non-trivial phenomenology, while its vector sector remains the same as in GR. In both branches, the tensor sector exhibits the usual HRBG features: an effective mass term and oscillations of the gravitons. Therefore MTBG provides a stable nonlinear completion of the cosmology in HRBG.

description: Background and study Objectives:
The recent pandemic has highlighted the need for increased digital health technology approaches, especially telemedicine, in addressing the health needs of individuals (Hyder & Razzak, 2020). Digital health technologies offer many opportunities to optimize and improve health care delivery and to reach underserved populations. Regulation of digital health technologies is the responsibility of different local or/and state authorities, with implications for manufacturers, providers, patients, and the health care systems Several challenges for digital health technology interventions exist, including regulatory approval and certification, legal and ethical issues, patient privacy, data security and reimbursement policies (Solimini et al., 2021; Stroetmann et al., 2012).
Appropriate regulatory measures are necessary to take advantage of the opportunities of digital health technologies (Torous et al., 2022). This study aims to identify and map barriers and facilitators in pre- and post-market regulation regarding the introduction and utilisation of digital health technologies.
In this mapping review, digital health technologies refer to health technologies as defined by the Food and Drugs Administration of the United States of America, including “systems that use computing platforms, connectivity, software, and/or sensors for healthcare and related uses” including for instance, mobile health (mHealth), health information technology (IT), wearable devices, telehealth and telemedicine, and personalized medicine (FDA, 2020; FDA 2022).

Main study question
What regulatory barriers and facilitators exist for the introduction and utilisation of digital health technologies?
Study Objectives
1. Identify and map barriers and facilitators in pre- and post-market regulation regarding the introduction and utilization of digital health technologies.
2. Derive lessons learned in the regulation of digital health technologies, especially for developing countries.

description: Children intuitively attribute social disparities to personal causes, known as “essentialist” reasoning (when these causes are stable and intrinsic, such as internal biology or inborn nature) or merely personal reasoning (when these causes are more flexible, such as personal choices or behaviors). This reasoning is associated with prejudice and stereotyping toward low-status groups, among children and adults, because (among other mechanisms) it leads children to view low-status groups as intrinsically deficient rather than extrinsically disadvantaged. (See Peretz-Lange, 2021 and Rhodes & Mandalaywala, 2017 for reviews).

Increasingly, research has focused on children’s capacity to counterintuitively attribute social disparities to structural causes, such as stable differences in people’s circumstances, resources, or access to opportunities. In this emergent literature, structural reasoning has been widely portrayed as an antidote to essentialist reasoning, enabling children to avoid forming prejudices and stereotypes. (See Amemiya et al., 2022 and Zhang et al., 2023 for reviews). This work generally portrays essentialist reasoning as socially pernicious, and structuralist reasoning as a socially favorable alternative.

In the present study, I aim to add nuance to this portrayal of structural explanations as a remedy to prejudice and stereotyping. I argue that structural reasoning could, just like essentialist reasoning, promote group-based social judgments. I predict that, just as personal explanations support group-based generalizations (stereotyping), so too do structural explanations. In other words, when children learn a structural explanation for why a member of Group A is higher-achieving than a member of Group B, these children will go on to expect other members of Group B to be low-achieving relative to members of Group A.

description: The management of the anthropogenic water cycle must ensure the preservation of the quality and quantity of water resources and their careful allocation to the different uses. Protection of water resources requires the control of pollution sources that may deteriorate them. This is a challenging task in multi-stressed catchments. This work presents an approach that combines pesticide occurrence patterns and stable isotope analyses of nitrogen (delta15N-NO3-, delta15N-NH4+), oxygen (delta18O-NO3-), and boron (delta11B) to discriminate the origin of pesticides and nitrogenpollution to tackle this challenge. The approach has been applied to a Mediterranean subcatchment subject to a variety of natural and anthropogenic pressures. Combining the results from both analytical approaches in selected locations of the basin, the urban/industrial activity was identified as the main pressure on the quality of the surface water resources, and to a large extent also on the groundwater resources, although agriculture may play also an important role, mainly in terms of nitrate and ammonium pollution. Total pesticide concentrations in surface waters were one order of magnitude higher than in groundwaters and believed to originate mainly from soil and/or sediments desorption processes and urban and industrial use, as they were mainly associated with treated wastewaters. These findings are supported by the stable isotope results, that pointed to an organic origin of nitrate in surface waters and most groundwater samples. Ammonium pollution observed in some aquifer locations is probably generated by nitrate reduction. Overall, no significant attenuation processes could be inferred for nitrate pollution. The approach presented here exemplifies the investigative monitoring envisioned in the Water Framework Directive.

description: One explanation for the disparity between Cold Dark Matter (CDM) predictions of galaxy numbers and observations could be that there are numerous dark galaxies in the Universe. These galaxies may still contain baryons, but no stars, and may be detectable in the 21cm line of atomic hydrogen. The results of surveys for such objects, and simulations that do/do not predict their existence, are controversial. In this paper we use an analytical model of galaxy formation, consistent with CDM, to firstly show that dark galaxies are certainly a prediction of the model. Secondly, we show that objects like VIRGOHI21, a dark galaxy candidate recently discovered by us, while rare are predicted by the model. Thirdly, we show that previous 'blind' HI surveys have placed few constraints on the existence of dark galaxies. This is because they have either lacked the sensitivity and/or velocity resolution or have not had the required detailed optical follow up. We look forward to new 21cm blind surveys (ALFALFA and AGES) using the Arecibo multi-beam instrument which should find large numbers of dark galaxies if they exist.

description: The classical principal chiral model in 1+1 dimensions with target space a compact Lie supergroup is investigated. It is shown how to construct a local conserved charge given an invariant tensor of the Lie superalgebra. We calculate the super-Poisson brackets of these currents and argue that they are finitely generated. We show how to derive an infinite number of local charges in involution. We demonstrate that these charges Poisson commute with the non-local charges of the model.

description: We compare three major large-scale hydrodynamical galaxy simulations (EAGLE, Illustris-TNG, and SIMBA) by forward modeling simulated galaxies into observational space and computing the fraction of isolated and quiescent low mass galaxies as a function of stellar mass. Using SDSS as our observational template, we create mock surveys and synthetic spectroscopic and photometric observations of each simulation, adding realistic noise and observational limits. All three simulations show a decrease in the number of quiescent, isolated galaxies in the mass range $\mathrm{M}_* = 10^{9-10} \ \mathrm{M}_\odot$, in broad agreement with observations. However, even after accounting for observational and selection biases, none of the simulations reproduce the observed absence of quiescent field galaxies below $\mathrm{M}_*=10^{9} \ \mathrm{M}_\odot$. We find that the low mass quiescent populations selected via synthetic observations have consistent quenching timescales, despite apparent variation in the late time star formation histories. The effect of increased numerical resolution is not uniform across simulations and cannot fully mitigate the differences between the simulations and the observations. The framework presented here demonstrates a path towards more robust and accurate comparisons between theoretical simulations and galaxy survey observations, while the quenching threshold serves as a sensitive probe of feedback implementations.

description: A significant fraction of ultraluminous X-ray sources appear to be embedded in observable ionized nebulae that take the form of large, several 100 pc diameter interstellar bubbles. Here we review optical observations of these bubbles, their importance for our understanding of the nature of ULXs, the energetics involved and their formation and evolution. Among the results obtained are new arguments against conventional superbubble scenarios and hypernova remnants, and we present the case in favour of ULX-wind/jet driven bubbles. We report the discovery of new ULXs in very large SNR candidates in nearby galaxies, and finally present an image of a triple X-ray source coincident with the radio-bright bubble S26 in the galaxy NGC 7793 which appears to be a clone of the microquasar SS433/W50 system.

Αρχικά, αναλύσαμε την έννοια των βασανιστηρίων σε διεθνές και ημεδαπό επίπεδο ενώ παράλληλα παραθέσαμε τα κυριότερα νομικά κείμενα που απαγορεύουν τέτοιες πρακτικές. Στη συνέχεια, επιχειρήσαμε μία προσέγγιση του πολύπλοκου ζητήματος της αναζήτησης των αιτιών που προκαλούν τέτοιες πράξεις και στο πλαίσιο αυτό εκθέσαμε το ιστορικό του πειράματος Stanford. Ακόμη, παρουσιάσαμε αναλυτικά τις συνθήκες κράτησης που επικρατούν σήμερα στα σωφρονιστικά καταστήματα της Ελλάδας ενώ εξετάσαμε και την αποκαταστατική ευθύνη των κρατών απέναντι στα θύματα και στις οικογένειές τους. Ακολούθως, παραθέσαμε τις σημαντικότερες καταδίκες της Ελλάδας από το ΕΔΔΑ την τελευταία δεκαπενταετία. Τέλος, η εργασία ολοκληρώθηκε με την αναφορά στα συνιστώμενα μέτρα για την πρόληψη των βασανιστηρίων και την επίτευξη καλύτερων συνθηκών στις φυλακές.
description: The aim of the present thesis was the study of the phenomenon of torture and other offenses against human dignity in contemporary times. First, we analyzed the meaning of torture on an international and domestic level, while at the same time we delivered the prevailing legal texts that prohibit such practices. Then, we attempted an approach to the complex issue of search of the reasons that cause such acts and in this context we reported the history of the Stanford experiment. Furthermore, we presented thoroughly the conditions of detention prevailing today in the prisons of Greece and we also examined the restorative responsibility of states to the victims and their families. Subsequently, we mentioned the most significant convictions of Greece by the European Court of Human Rights in the last fifteen years. Finally, the thesis was completed by reference to the recommended measures for the prevention of torture and the attainment of better prison conditions.
An effective field theory approach to fermionic rotational bands in nuclei

description: We extend an effective field theory developed to describe rotational bands in even-even nuclei to the odd-mass case. This organizes Bohr and Mottelson's treatment of a particle coupled to a rotor as a model-independent expansion in powers of the angular velocity of the overall system. We carry out this expansion up to fourth order in the angular velocity and present results for $^{99}$Tc, ${}^{159}$Dy, ${}^{167, 169}$Er, ${}^{167, 169}$Tm, ${}^{183}$W, ${}^{235}$U and ${}^{239}$Pu. In each case, the accuracy and breakdown scale of the effective field theory can be understood based on the single-particle and vibrational energy scales in that nucleus.

description: For certain algebraic Hecke characters chi of an imaginary quadratic field F we define an Eisenstein ideal in a p-adic Hecke algebra acting on cuspidal automorphic forms of GL_2/F. By finding congruences between Eisenstein cohomology classes (in the sense of G. Harder) and cuspidal classes we prove a lower bound for the index of the Eisenstein ideal in the Hecke algebra in terms of the special L-value L(0,chi). We further prove that its index is bounded from above by the order of the Selmer group of the p-adic Galois character associated to chi^{-1}. This uses the work of R. Taylor et al. on attaching Galois representations to cuspforms of GL_2/F. Together these results imply a lower bound for the size of the Selmer group in terms of L(0,chi), coinciding with the value given by the Bloch-Kato conjecture.
