description: System-size dependence of dihadron azimuthal correlations in ultra-relativistic heavy ion collision is simulated by a multi-phase transport model. The structure of correlation functions and yields of associated particles show clear participant path-length dependences in collision systems with a partonic phase. The splitting parameter and root-mean-square width of away-side correlation functions increase with collision system size from $^{14}$N+$^{14}$N to $^{197}$Au+$^{197}$Au collisions. The double-peak structure of away-side correlation functions can only be formed in sufficient "large" collision systems under partonic phase. The contrast between the results with partonic phase and with hadron gas could suggest some hints to study onset of deconfinment.

Self-consistent nonspherical isothermal halos embedding zero-thickness disks

description: Disk-halo decompositions of galaxy rotation curves are generally performed in a parametric way. We construct self-consistent models of nonspherical isothermal halos embedding a zero-thickness disk, by assuming that the halo distribution function is a Maxwellian. The method developed here can be used to study other physically-based choices for the halo distribution function and the case of a disk accompanied by a bulge. In a preliminary investigation we note the existence of a fine tuning between the scalelengths R_Ω and h, respectively characterizing the rise of the rotation curve and the luminosity profile of the disk, which surprisingly applies to both high surface brightness and low surface brightness galaxies. This empirical correlation identifies a much stronger conspiracy than the one required by the smoothness and flatness of the rotation curve (disk-halo conspiracy). The self-consistent models are characterized by smooth and flat rotation curves for very different disk-to-halo mass ratios, hence suggesting that conspiracy is not as dramatic as often imagined. For a typical rotation curve, with asymptotically flat rotation curve at V_{\infty} (the precise value of which can also be treated as a free parameter), and a typical density profile of the disk, self-consistent models are characterized by two dimensionless parameters, which correspond to the dimensional scales (the disk mass-to-light ratio M/L and the halo central density) of standard disk-halo decompositions. We show that if the rotation curve is decomposed by means of our self-consistent models, the disk-halo degeneracy is removed and typical rotation curves are fitted by models that are below the maximum-disk prescription. Similar results are obtained from a study of NGC 3198. Finally, we quantify the flattening of the spheroidal halo, which is significant, especially on the scale of the visible disk.

Grain refinement of B319 alloy using spark plasma sintered Al-Ti-C grain refiners
Creators: name: Mok, Justin Alfred
Publisher: name: University of British Columbia
Year: 2018

description: The B319 aluminum alloy is a candidate material for automotive applications, where engineers and materials designers are seeking to improve vehicle efficiency through vehicle weight reduction. Although the alloy has many desirable properties, such as it’s excellent castability and moderate strength to weight ratio, continued efforts on further enhancement of the alloy’s strength via the grain refinement approach have been reported. However, in addition to the fundamental challenges related to solidification phenomena, there also remain several challenges related to the efficient dispersion of inoculating particles in the liquid alloy during casting, as well as its casting characteristics (e.g., fluidity) as a result of the grain refinement. Further, a method for fabricating effective and homogenous grain refining master alloys remains a challenge. This research focused on examining the grain refining ability of various grain refiners produced via the spark plasma sintering (SPS) powder metallurgy route. Analysis of solidification events was used to track phase evolution and its effect on the final grain size and also on the alloy’s fluidity. The mechanical properties of the as-cast material were measured via tensile tests according to ASTM B557M standard. The results indicate that SPS enabled production of a homogenous grain refining master alloys for metal casting. Two grain refiners (Aluminum-Titanium Carbide [Al-TiC] and Aluminum-Titanium-Carbon Black [Al-TiCB]) were produced at high and low concentrations and added to the molten B319. The high concentration formulations for both Al-TiC and Al-TiCB had the greatest effect on the properties of the B319 aluminum alloy, as a result of achieving a reduction in the average grain size of 31% and 25%, respectively. Concurrently, these grain refiners increased the ultimate tensile strength by 6% and 8%, respectively. The flow length of the B319 was reduced by 15%, 31%, 29%, and 32% after addition of Al-1TiC, Al-5TiC, Al-1TiCB and Al-5TiCB, respectively, thus suggesting the need for further work in optimizing the casting parameters to achieve optimal casting fillability.

description: New grids of Atlas9 models have been calculated using revised convection parameters and updated opacity-distribution functions, for chemical compositions intended to be representative of solar, [M/H] = +0.3, +0.5, Large Magellanic Cloud (LMC), and Small Magellanic Cloud (SMC) abundances. The grids cover T(eff) = 3.5-50kK, from log(g) = 5.0 to the effective Eddington limit. Limb-darkening coefficients and synthetic photometry are presented in the UBVRIJHKLM, uvby, ugriz, WFCAM, Hipparcos/Tycho, and Kepler passbands for these models, and for Castelli's comparable `new-ODF' grids. Flux distributions are given for the new models. The sensitivity of limb-darkening coefficients to the adopted physics is illustrated.

description: We extend our previous work on the functional approach to the dynamical Casimir effect, to compute dissipative effects due to the relative motion of two flat, parallel, imperfect mirrors in vacuum. The interaction between the internal degrees of freedom of the mirrors and the vacuum field is modeled with a nonlocal term in the vacuum field action. We consider two different situations: either the motion is `normal', i.e., the mirrors advance or recede changing the distance $a(t)$ between them; or it is `parallel', namely, $a$ remains constant, but there is a relative sliding motion of the mirrors' planes. For the latter, we show explicitly that there is a non-vanishing frictional force, even for a constant shifting speed.

description: We report the details of the construction and calibration of an ultra sensitive surface rheometer, inspired by the setup described in [C.F. Brooks et al Langmuir 15, 2450 (1999)], which makes use of high resolution video tracking of the motion of a floating magnetized needle and is capable of measuring the viscoelastic response of a Langmuir monolayer with an accuracy of 10^-5 N/m. This instrument is then employed for the rheological characterization of a Langmuir monolayer of a photosensitive azobenzene polymer, which can be brought out of equilibrium by a suitable photoperturbation. The complex dynamic shear modulus G= G' + i G" is measured as a function of temperature and illumination power and wavelength. The reversible rheological ch anges induced in the film by photo-perturbation are monitored during time, observing a transition from a predominantly elastic (G' > G'') to a viscoelastic (G' \approx G'') regime. These results are confirmed by comparison with independent measurements performed by us using other rheological techniques. Finally a discussion is made, taking into account the results of a recent x-ray photon correlation spectroscopy experiment on the same polymer in equilibrium and out of equilibrium.

description: We report the results of molecular dynamics simulations of an off-lattice protein model featuring a physical force-field and amino-acid sequence. We show that localized modes of nonlinear origin (discrete breathers) emerge naturally as continuations of a subset of high-frequency normal modes residing at specific sites dictated by the native fold. In the case of the small $β$-barrel structure that we consider, localization occurs on the turns connecting the strands. At high energies, discrete breathers stabilize the structure by concentrating energy on few sites, while their collapse marks the onset of large-amplitude fluctuations of the protein. Furthermore, we show how breathers develop as energy-accumulating centres following perturbations even at distant locations, thus mediating efficient and irreversible energy transfers. Remarkably, due to the presence of angular potentials, the breather induces a local static distortion of the native fold. Altogether, the combination of this two nonlinear effects may provide a ready means for remotely controlling local conformational changes in proteins.

description: We determine the chiral phase transition line in (2+1)-flavor QCD for small values of the light quark chemical potential. We show that for small values of the chemical potential the curvature of the phase transition line can be deduced from an analysis of scaling properties of the chiral condensate and its susceptibilities. To do so we extend earlier studies of the magnetic equation of state in (2+1)-flavor QCD to finer lattice spacings, aT=1/8. We use these universal scaling properties of the chiral order parameter to extract the curvature of the transition line at two values of the cut-off, aT=1/4 and 1/8. We find that cut-off effects are small for the curvature parameter and determine the transition line in the chiral limit to leading order in the light quark chemical potential. We obtain Tc(μ_q)/Tc(0) = 1 - 0.059(2)(4) (μ_q/T)^2 +O(μ_q^4).

Late Cenozoic post-subduction tectonic, magmatic and metallogenic evolution of the Anatolide-Tauride Orogenic Belt, Turkey
Creators: name: Rabayrol, Fabien
Publisher: name: University of British Columbia
Year: 2018

description: The termination of the northward subduction of the Southern Neotethyan oceanic slab beneath the Anatolide-Tauride Block in Turkey led to the onset of the Arabia-Eurasia continental collision in the Oligocene. The subducting Southern Neotethyan slab was affected by post-subduction segmentation manifested by slab break-off (central-eastern Anatolia) and tearing (western Anatolia) during the late Cenozoic. Many igneous complexes formed in the late Cenozoic and some of them host gold-rich porphyry and epithermal prospects and deposits. New temporal (U-Pb, ⁴⁰Ar/³⁹Ar and Re-Os dates), spatial (field observations and GIS) and geochemical data (elemental and Sr-Nd-Pb isotopic analyses) provide robust constraints on the genetic relationship between late Cenozoic slab segmentation tectonic events, Anatolian magmatism and associated gold mineralization. The newly-defined Eastern Anatolian Magmatic Belt formed in response to the slab break-off initiation at ca. 25 Ma, window opening, westward break-off propagation to central Anatolia and induced asthenospheric flow. The slab break-off-related igneous units were subsequently covered by widespread volcanic products in eastern Anatolia (12 Ma – Present) that resulted from the long-lived asthenospheric heating, destabilization of the thickened Anatolian lithosphere root and its partial removal by convective dripping. Magmatic sources include the shallow melting of the previously-metasomatized Anatolian subcontinental lithospheric mantle and asthenosphere by decompression due to impingement of the Arabian and African sub-slab asthenospheric mantles. Late Cenozoic Anatolian magmatism produced porphyry and epithermal prospects and deposits that cluster in nine isolated mineral districts controlled by graben, transtensional corridors and pull-apart basins. The bulk of gold mineralization (33 Moz Au) peaked at the beginning of the slab break-off event at 25 Ma in central and eastern Anatolia, and slab tear at 15 Ma in western Anatolia. The late Cenozoic trench-parallel and -perpendicular migrations of slab rupture and window opening in Anatolia 1) allowed toroidal and poloidal flow of asthenosphere beneath Anatolia, 2) caused the migration of melting source and associated igneous complexes and mineral deposits in the overriding crust, 3) destabilized the Anatolian lithospheric mantle, which reduced the amount of available volatiles and metals, and therefore 4) increased the production of barren, drier and mantle-dominant volcanism through time that partially covers fertile igneous units.

description: Mercury has fascinated researchers for decades due to its sizable metallic core and weak magnetic field. The behavior of model compositions provide constraints on core conditions and regimes of solidification to predict magnetic field strength. In this study, we investigate the melting behavior of the Fe-Ni-S system, an analog composition of the Mercurian core, using a multi-anvil apparatus. We observe that the Fe-S liquidus has an inflection point at ~10 wt.% S at 14 GPa and ~11.5 wt.% S at 24 GPa, while (Fe, Ni)-S does not. At 24 GPa, Ni lowers the melting point of the Fe-S system by as much as 300 C, indicating that solidification models and adiabatic calculations must account for the presence of Ni.

These results together with our previous result indicate that two-instanton solution and two-meron solution with the same asymptotic behavior in the long distance are responsible for quark confinement based on the dual superconductivity picture.

description: Olivine-melt thermometry, based on the partitioning of Ni, is applied to 13 lavas (absarokites, olivine minettes, basaltic andesites and a hornblende lamprophyre) from the Mascota volcanic field in western Mexico, to determine the onset temperature for olivine phenocryst growth during ascent. A test of whether the most Mg-rich olivine analyzed in each sample is a close approximation of the first olivine to crystallize from a melt composition that matches the whole rock was made using the thermodynamic MELTS model and shown to be consistent in all but one case. One sample with 16 wt% MgO, shows possible evidence of olivine accumulation, whereas the remaining 12 samples indicate that olivine crystallization began at ~1200 C for the absarokites (~11.7 wt% MgO), ~1150 C for the olivine minettes (~8.5 wt% MgO), ~1100-1030 C for the basaltic andesites (~ 8.7-7.0 wt% MgO), and as low as ~954 C for the hornblende lamprophyre. (~6 wt% MgO). These olivine-melt thermometry results are fully consistent with hydrous phase-equilibrium experiments from the literature. Moreover, all samples contain olivine phenocrysts with diffusion-limited rapid-growth textures, consistent with phenocryst growth driven by H2O degassing and cooling during ascent, which leads to large effective undercoolings that cannot be attained in a magma undergoing cooling by conductive loss of heat in a crustal chamber. In addition to Nibased olivine-melt thermometry, for which dissolved H2O in the melt has a negligible 2 effect, the application of Mg-based olivine-melt thermometry to the same samples allows the magnitude of the suppression of olivine crystallization temperatures due to dissolved water in the melt to be evaluated. The results show that olivine liquidus temperatures have been reduced by 95-234 ( 29) C, indicative of dissolved water concentrations that range from >3-8wt% H2O, consistent with hydrous phase-equilibrium experiments. Finally, application of Fe2+-Mg exchange coefficient (KD) values from the literature to the olivine-melt pairs used for thermometry constrain melt Fe3+/FeT ratios (0.25-0.49) at the onset of olivine growth; these values correspond to oxygen fugacities that range from 1 to 3 log units above that of the Ni-NiO buffer. The results of this study show that these 12 Mascota lavas, which display a strong arc geochemical signature (e.g., high Ba/Zr ratios) are both hydrous (≤ 8 wt%) and oxidized (ΔNNO ≤ +3).

description: A sample of dentin and cementum removed from the growing end of the left tusk of the Bowser Road mastodon was analyzed to document structural variation and interpret season of death for this individual. Within this tusk sample, we investigated three different patterns of structural variation: repeated step-wise changes in X-ray attenuation of dentin along transects perpendicular to the surface of the tusk pulp cavity (the surface of dentin apposition), highly variable but roughly cyclical variation in the thickness of structural increments of dentin (again measured normal to the surface of the pulp cavity), and topographic features expressed on the external surface of the tusk, encircling its root and paralleling its proximal margin. These three patterns of structural variation are linked in that each is initially manifested in dentin, and each occurs over a spatial scale determined by annual rates of dentin apposition and tusk extension. Based on previously documented associations between the structural features observed here and individual seasons comprising the annual cycle, we treat our annual increments as extending from one winter-spring boundary to the next. We also confirm that the structural increments for which we document the pattern of thickness variation formed periodically, spanning intervals of about one fortnight (two weeks) each. In a transverse thin section from a position near the middle of our sample slab, we observed two complete years of growth and a final interval of fifteen fortnights. This implies an early autumn season of death for the Bowser Road mastodon. In prior work, autumn deaths were probabilistically associated with active hunting by humans.
title: MicroRNA-184: A Multifaceted Regulator of Epidermal Keratinocyte Biology
Creators: name: Richardson, A
Publisher: name: Liverpool John Moores University
Year: 2019

description: The epidermis is vitally important in protecting the organism from environmental insults. Consisting of dynamic outer strata of keratinocytes that terminally differentiate from basal keratinocytes stem cells (KSC), the epidermis is maintained by constant spatial and temporal control. In psoriasis, a dysregulated and intensifying crosstalk between keratinocytes and immune cells disturbs epidermal homeostasis resulting in hyperproliferation and loss of differentiation. Recently, short (~22 nt) genetic molecules called microRNAs (miRNA) that regulate gene expression by repressing messenger RNA (mRNA) have gained attention as robust regulators of keratinocyte biology and key players in psoriasis. A specific miRNA elevated in psoriasis, miR-184, modulates the expression of Argonaute 2 (AGO2), an established effector of miRNA function. However, there is a paucity of research investigating miR-184 and the miR-184:AGO2 axis in epidermal keratinocyte biology. As such, the aim of this thesis was to delineate miR-184 expression and function during keratinocyte proliferation, differentiation and migration. Firstly, it was revealed that miR-184 was induced during keratinocyte differentiation in a process that relies exclusively on Ca2+ and the major keratinocyte Ca2+ entry pathway called store-operated calcium entry (SOCE). Furthermore, miR-184 was upregulated in a cohort of eight psoriasis patient samples. By modulating miR-184 expression it was elucidated that miR-184 promotes early keratinocyte differentiation through concomitant induction of factors related to DNA damage, growth arrest and terminal differentiation. In addition, this thesis reports the discovery of SOCE-dependent induction of miR-184 during keratinocyte migration as well as a long non-coding RNA, UCA1 that has been implicated in the regulation of miR-184. Importantly, ectopic miR-184 stimulated keratinocyte migration in scratched monolayers while inhibition of miR-184 reduced migration. Studies on AGO1-4 transcripts identified that AGO4 mRNA was the most abundant AGO in human epidermal keratinocytes and revealed no reduction of AGO2 expression in response to enhanced miR-184 levels during differentiation. Furthermore, both AGO1 and AGO4 were downregulated in psoriatic patients. Finally, it was established that AGO2 localises to the nucleus of terminally differentiated keratinocytes in a Ca2+-dependent mechanism, pointing to an apparent nuclear role for AGO2 during keratinocyte differentiation. In summary, the results reported in this thesis highlight an important role for miR-184 in the regulation of epidermal keratinocyte biology, reveal SOCE as a regulator of miRNA pathways in keratinocytes and show for the first time a role for miR-184 in epidermal keratinocyte migration. Together, these studies may facilitate the development of miRNA based dermaceuticals for cutaneous diseases.

description: Using a two-component model for charmonium production, which includes contributions from both the initial hard nucleon-nucleon scattering and from the regeneration in the quark-gluon plasma, we study the nuclear modification factor $R_{AA}$ and elliptic flow $v_2$ of $J/ψ$ in relativistic heavy ion collisions. For the expansion dynamics of produced hot dense matter, we introduce a schematic fireball model with its transverse acceleration determined from the pressure gradient inside the fireball and azimuthally anisotropic expansion parameterized to reproduce measured $v_2$ of light hadrons. We assume that light hadrons freeze out at the temperature of 120 MeV while charmonia at 160 MeV, similar to the kinetic and chemical freeze-out temperatures in the statistical model, respectively. For the properties of charmonia in the quark-gluon plasma, we use the screening mass between their charm and anticharm quarks and their dissociation cross sections given by the perturbative QCD (pQCD) in the leading order and up to the next-to-leading order, respectively. For the relaxation time of charm and anticharm quarks in the quark-gluon plasma, we also use the one calculated in the leading order of pQCD. Modeling the effect of higher-order corrections in pQCD by introducing multiplicative factors to the dissociation cross section of charmonia and the elastic scattering cross sections of charm and anticharm quarks, we find that this effect is small for the $R_{AA}$ of $J/ψ$ as they suppress the number of initially produced $J/ψ$ but enhance the number of regenerated ones. The higher-order corrections increase, however, the $v_2$ of $J/ψ$. Our results suggest that the $v_2$ of $J/ψ$ can play an important role in discriminating between $J/ψ$ production from the initial hard collisions and from the regeneration in the quark-gluon plasma.

description: Photochemical, or light-driven, processing of dissolved organic matter (DOM) in inland waters can completely degrade DOM to carbon dioxide (CO2), a greenhouse gas, through photomineralization or partially degrade DOM through partial photo-oxidation. Evidence suggests that the lability of DOM, quantified as an apparent quantum yield (AQY, fλ), is not constant with increasing light exposure. Thus, the rate of photochemical processing is not constant during light exposure in sunlit surface waters as DOM f λ changes. Findings in this study show that fPM,λ (photo-mineralization) typically decreases as photon dose increases, while fPPO,λ (partial photooxidation) does not show a consistent trend. Differences in DOM chemistry between sites and dates sampled are likely controlling differences in fPM,λ and fPPO,λ trends with increasing photon dose. Daily areal rates of photo-mineralization calculated with fPM,λ after a low photon dose are an overestimate by a factor of 2.08 0.18 compared to rates calculated with fPM,λ from a higher photon dose, while daily areal rates of partial photo-oxidation calculated with fPPO,λ after a low photon dose are an overestimate by a factor of 1.15 0.10 compared to rates calculated with fPPO,λ from a higher photon dose. Because partial photo-oxidation fPPO,λ does not show a consistent trend with increasing photon dose, the impact of low vs. high photon dose experimentally determined fPPO,λ on calculated areal rates is not as large as the impact of fPM,λ. Understanding how photon dose and DOM chemistry control the photochemical degradation of DOM will further constrain current estimates of how much CO2 and partially-oxidized DOM is produced through photochemical processes in these arctic surface waters.

description: Global mobility programs for pre-service teachers are an increasingly integral component of many teacher education courses. Such programs are perceived as an important opportunity for pre-service teachers to engage with diversity and to develop skills to respond to increasingly multicultural and multilingual classrooms. Research into international teaching practicums has shown that student teachers develop intercultural awareness, inclusive teaching practices and flexibility, but global mobility programs can also reinforce cultural stereotypes, neocolonial attitudes and a sense of superiority and entitlement. This paper presents a comparative analysis of pre-service teachers’ experiences in two mobility programs—a German program undertaken in Laos, and an Australian program in Chile. Such a comparison has two aims: first, to explore and add to current understandings of transnationalism; and second, to examine how binary categories of self and other, which are historically constructed and discursively produced, continue to shape intercultural encounters From this arises the need to support pre-service teachers in finding new discursive ways to engage with the complexity of their experiences and their expanding sense of identity.
title: Fragmentation and melting of the seasonal sea ice cover

description: The Arctic sea ice cover is in retreat. Accurate representation of the marginal ice zone (MIZ), the region of the sea ice cover that separates open ocean from the pack ice, is important to capture this retreat in models. The MIZ is associated with complex interactions of the atmosphere, sea ice, and oceans, and a highly heterogenous sea ice cover. Several important sea ice properties and processes that determine the evolution of the MIZ, including lateral melting, momentum exchange, and sea ice rheology, are dependent on floe size. Climate models have historically treated floe size as a fixed parameter, if at all. Observations have shown that floes adopt sizes from scales of metres to kilometres. Here I investigate two alternative models of the floe size distribution (FSD). The first approach assumes the FSD follows a power law with a fixed exponent and the second approach is a prognostic floe size-thickness distribution model where the shape of the FSD freely evolves. These models are used to understand how variable floe size in the MIZ changes the seasonal retreat of the Arctic sea ice cover, both through the impact on lateral melt volume and on momentum exchange coefficients. I discuss the advantages and disadvantages of each approach, including an assessment of whether either model improves sea ice model performance compared to observations. I find a high sensitivity to poorly constrained FSD parameters and parameterisations, highlighting the need to better characterise the FSD with observations. I show that winter floe formation and growth processes strongly influence FSD impacts on the sea ice over the melt season. I also demonstrate the need to incorporate brittle fracture in FSD models. I conclude that simple representations of floe size are sufficient to project future sea ice trends, but FSD models are important to capture the spatial distribution of the sea ice.

description: Young pelagic, planktivorous fish species feed on phytoplankton and zooplankton larvae, which respond to nutrient delivery by upwelling. Off the coast of Southern California, wind-driven coastal upwelling is affected by the position and strength of the North Pacific High Pressure system (NPH). When NPH strength increases, coastal upwelling intensifies and dry climate conditions prevail. Here we determine the abundance of four pelagic fish species; Northern anchovy (Engraulis mordax), Pacific sardine (Sardinops sagax), hake (Merluccius productus), and surfperch (Embiotocidae spp.), in Santa Barbara Basin (SBB) over the last 1500 years and relate population fluctuations to regional upwelling and the strength of the NPH. Proxies for marine productivity, drought and surface water masses based on sediment geochemistry are used to reconstruct NPH strength and surface ocean circulation. Sediment core SPR0901-02KC was collected from the SBB (34 16.8′ N, 120 02.3′ W) and sampled continuously at 0.5 cm resolution (~5-year resolution) for fish scale counts from which scale deposition rates (SDR) and relative abundance (%) were estimated. Anchovy scales generally comprise >50% of total scales. Anchovy SDRs were >30 scales cm-2 year-1 1000 between 510-675, 860-1075, 1425, 1500, 1560-1700 and 1750-1825, and 1870-1900 CE when the NPH was strong producing both intense coastal upwelling and drought in Southern California. Sardine SDRs (<20% of scales) were generally in phase with anchovy, with lower and more variable abundance. Sardine comprise >10% of scales between 680-875, 1050-1300, 1340-1380, 1480-1510 and 1690-1740 CE. Hake scales comprise ~30-50% of total scales and are most abundant between 760-1030 and 1275- 1470 CE when Eastern Tropical North Pacific water entered the basin, with a maximum SDR of ~35 scales cm-2 year-1 1000. Surfperch scales generally comprise <10% of total scales. Anchovy abundance increases during intervals supporting a strengthening of the NPH, while hake respond to variations in poleward currents. Sardine and surfperch have no notable correlations with these environmental factors.
title: An intertextual reading of female characters in Margaret Atwood’s work

description: The intertextual dialogue in a selection of Margaret Atwood’s novels is the focus of this thesis. The chapters analyse four novels: The Edible Woman, Surfacing, The Handmaid’s Tale and Cat’s Eye. Chapter 1 posits the theoretical framework, drawing ideas from Bakhtin, Kristeva, Riffaterre, Hutcheon and Foucault. The intertextual conversation in Atwood’s novels questions traditional narratives in a continuous exchange that generates visions that are alternatives to the roles and rules of the androcentric society. The frequent use of intertexts allows a ‘dialogic thought’ that opens up to multiple diverse visions that deny dichotomous restrictive roles that are implemented through traditional narratives in schools and families in a consumerist and exploitative perspective. The openness to different views gives space to a broader human vision and possible multiple readings in a continuous relationship and conversation with the Other that generates identities in flux; it is a never-ending process that creates new meanings in changing contexts where opposites coexist. The incongruous roles proposed by society are therefore exposed as restrictive and menacing and new approaches are proposed that aim for human survival. From this view, humanity is saved in a process of continuous questioning that is selfreflexive as well as in tension with previous narratives from high and low culture and traditional and contemporary discourses where the angle continuously shifts in a revolutionary mode. This entails the intertextual ‘dialogic thought’, the disruptive vision of écriture féminine and the position of the reader function in conversation with the writer function within the novels. Various readings are therefore proposed without a definite closure, allowing further developments that go beyond the ending in a world of language where ‘reality’ is constructed in words. Atwood’s literary world is representative of a political and social context and, at the same time, challenges this ‘reality’ in an attempt to rewrite these narratives from within through the intertextual conversation.
