Experimental diabetes in ß6 integrin deficient mice
Creators: name: Aurora, Saljae
Publisher: name: University of British Columbia
Year: 2009

description: Objectives: Periodontal disease involves transformation of the junctional epithelium (JE) to a pocket epithelium (PE). Integrin avß6 is constitutively expressed in the healthy IF but not in PE. Mice deficient of this integrin (ß6-/-) exhibit increased periodontal bone loss and PE migration. Thus, avß6 integrin in JE may have a protective role against periodontal disease. As diabetes aggravates periodontal disease, we hypothesized that diabetic ß6-/- mice would develop more advanced periodontal disease compared to nondiabetic mice. Furthermore, we hypothesize that re-introduction of ß6 integrin under the cytokeratin 14 (Ki 4) gene promoter in the ß6-/- strain, would restore protection against periodontal disease. Methods: Wild-type (WIT), ß6-/-, ß6 integrin over-expressing (Kl4ß6; ß6 integrin expression is driven by Ki 4 promoter) and ß6 integrin rescue (ß6-rescue; cross-breed of ß6-/- and K14ß6 mice) mice were induced to develop diabetes by injections of streptozotocin, and confirmed diabetic 2 weeks later (Blood glucose >306 mg/dl (17 mmollL). Control animals were exposed to the citrate vehicle only. Four months later, mice were sacrificed. Mandibles were dc-fleshed and imaged for quantification of periodontal bone loss. Maxillae were decalcified and sectioned for histological assessment of epithelial migration and inflammation. Results: Diabetic ß6-/- mice (71% mortality) exhibited significantly higher death rates as compared to non-diabetic WT and K14ß6 groups. Epithelial migration for the ß6-/- strain was significantly higher than that seen in the W/T and the K14ß6 strains. (P<0.001). Significantly reduced epithelial migration was noted for the ß6 Rescue strain compared to ß6-/- strain. Periodontal bone loss was significantly greater in the male ß6-/- strain when combined with experimental diabetes (P<O.05), while experimental diabetes did not increase alveolar bone loss in other male groups. Female diabetic mice appear protected from alveolar bone loss. Inflammation was significantly greater for both the ß6 Rescue strain and ß6-/- strain relative to the W/T strain. Conclusions: Integrin avß6 protects diabetic animals from death and periodontal disease. Reductions in epithelial migration and mortality in the ß6 Rescue strain reinforce the role of avß6 integrin in suppressing inflammation. Diabetes can aggravate periodontal bone loss in male diabetic ß6-/- mice.

description: We discovered that perovskite (Ba,La)SnO3 can have excellent carrier mobility even though its band gap is large. The Hall mobility of Ba0.98La0.02SnO3 crystals with the n-type carrier concentration of \sim 8-10\times10 19 cm-3 is found to be \sim 103 cm2 V-1s-1 at room temperature, and the precise measurement of the band gap Δof a BaSnO3 crystal shows Δ=4.05 eV, which is significantly larger than those of other transparent conductive oxides. The high mobility with a wide band gap indicates that (Ba,La)SnO3 is a promising candidate for transparent conductor applications and also epitaxial all-perovskite multilayer devices.
Strong Splitter Theorem

Subjects: subject: Combinatorics (math.CO)

description: The Splitter Theorem states that, if $N$ is a 3-connected proper minor of a 3-connected matroid $M$ such that, if $N$ is a wheel or whirl then $M$ has no larger wheel or whirl, respectively, then there is a sequence $M_0,..., M_n$ of 3-connected matroids with $M_0\cong N$, $M_n=M$ and for $i\in \{1,..., n\}$, $M_i$ is a single-element extension or coextension of $M_{i-1}$. Observe that there is no condition on how many extensions may occur before a coextension must occur. In this paper, we give a strengthening of the Splitter Theorem, as a result of which we can obtain, up to isomorphism, $M$ starting with $N$ and at each step doing a 3-connected single-element extension or coextension, such that at most two consecutive single-element extensions occur in the sequence (unless the rank of the matroids involved are $r(M)$). Moreover, if two consecutive single-element extensions by elements $\{e, f\}$ are followed by a coextension by element $g$, then $\{e, f, g\}$ form a triad in the resulting matroid. Using the Strong Splitter Theorem, we make progress toward the problem of determining the almost-regular matroids [6, 15.9.8]. {\it Find all 3-connected non-regular matroids such that, for all $e$, either $M\backslash e$ or $M/e$ is regular.} In [4] we determined the binary almost-regular matroids with at least one regular element (an element such that both $M\backslash e$ and $M/e$ is regular) by characterizing the class of binary almost-regular matroids with no minor isomorphic to one particular matroid that we called $E_5$. As a consequence of the Strong Splitter Theorem we can determine the class of binary matroids with an $E_5$-minor, but no $E_4$-minor.

description: Nowadays there is an increasing interest of physicists in finding regularities related to social phenomena. This interest is clearly motivated by applications that a statistical mechanical description of the human behavior may have in our society. By using this framework, we address this work to cover an open question related to elections: the choice of elections candidates (candidature process). Our analysis reveals that, apart from the social motivations, this system displays features of traditional out-of-equilibrium physical phenomena such as scale-free statistics and universality. Basically, we found a non-linear (power law) mean correspondence between the number of candidates and the size of the electorate (number of voters), and also that this choice has a multiplicative underlying process (lognormal behavior). The universality of our findings is supported by data from 16 elections from 5 countries. In addition, we show that aspects of network scale-free can be connected to this universal behavior.

description: We consider a planar waveguide with combined Dirichlet and Neumann conditions imposed in a "twisted" way. We study the discrete spectrum and describe it dependence on the configuration of the boundary conditions. In particular, we show that in certain cases the model can have discrete eigenvalues emerging from the threshold of the essential spectrum. We give a criterium for their existence and construct them as convergent holomorphic series.

description: Der Einfluss des Protein- und Wasseranteils in Zahnschmelz auf dessen mechanische Eigenschaften wurde untersucht. Die Proteine wurden mittels therm. und chem. Behandlung entfernt und die Wirksamkeit dieser wurde durch Bestimmung des organischen Anteils überprüft. Eine chem. Behandlung erwies sich als geeigneter, da diese, im Gegensatz zur therm. Behandlung, keine Strukturveränderung im Zahnschmelz bewirkte. Strukturanalysen zeigten, dass die Grenzflächen nicht aus einer, die Kristalle umhüllenden, Proteinschicht bestehen, sondern durch häufige, direkte mineralische Kontakte definiert sind. Der Proteinanteil hatte keinen Einfluss auf E-Modul, Härte und Kriechverhalten. Ein erhöhter Wasseranteil, hingegen hatte einen reduzierten E-Modul, sowie vermehrtes Kriechen und Materialerholung zur Folge.
description: In this work, the influence of organic and water content in dental enamel on its mechanical properties was investigated. The effectiveness of the deproteinization treatments (heating and chemical treatment) were assessed by determining the organic content in enamel. Chemical treatment proved more suited for protein removal, as - contrary to heating - it does not alter enamel’s ultrastructure. Structural characterization revealed the interfaces in enamel having multiple mineral-to-mineral contacts, meaning that a protein layer, enveloping enamel’s crystallites, is absent. The protein content had virtually no effect on elastic modulus, hardness and creep behavior, as assessed by nanoindentation. However, a higher water content resulted in a lower elastic modulus and increased creep and recovery in the enamel.

description: We review the structure of gauge theory scattering amplitudes at tree level and describe how a compact expression can be found which encodes all the tree-level amplitudes in the maximally supersymmetric N=4 theory. The expressions for the amplitudes reveal a dual superconformal symmetry. We describe how these ideas can be extended to leading singularities and the loop integrand in the planar theory and discuss the appearance of dual conformal symmetry in higher-dimensional gauge theories.

description: Hydrodynamische Kräfte am schrägfahrenden Schiffsrumpf bei höheren Geschwindigkeiten im tiefen und flachen Wasser Es wird ein drei-dimensionales numerisches Verfahren zur Berechnung der stationären Potentialströmung und der hydrodynamischen Kräfte am einen schrägfahrenden Schiffsrumpf bei höheren Geschwindigkeiten im tiefen und flachen Wasser vorgestellt. Das Störpotential wird durch Verteilungen von Rankine-Quellen und eine halb-unendliche Dipolschicht dargestellt. Unter der Voraussetzung kleiner Driftwinkel wird die Umströmung in einen symmetrischen Anteil infolge der Längsbewegung und einen antimetrischen Anteil infolge der seitlichen Bewegung aufgeteilt; die symmetrische und die antimetrische Umströmung werden dann getrennt voneinander bestimmt.Rechnungen wurden für ein "Wigley-Modell" von 10 m Länge im tiefen und flachen Wasser durchgeführt. Die numerischen Ergebnisse für den Wellenwiderstand, die stationäre Absenkung und Vertrimmung, die Querkraft und das Giermoment sowie die Wellenerhebung wurden präsentiert. Das vorgestellte Verfahren wurde durch die Testrechnungen als funktionsfähig bewiesen. Weitere Verifikation und Verbesserungen des Verfahrens sind aber noch notwendig.
description: This paper describes a three-dimensional numerical approach for computing the steady potential flow and the hydrodynamical forces acting on ships of small angles of yaw at high speed in deep and shallow water. The disturbed velo city potential is expressed by a distribution of Rankine sources and a semi-infinite dipole sheet. Based on the assumption that the angles of yaw are small, the flow is splitted into asymmetrie one due to the longitudinal motion of the ship and an antisymmetrie one due to the lateral motion; the symmetrie flow and the antisymmetrie flow are then determined respectively. Calculations were performed for a Wigley model 10 m long. Numerical results, i.e.,the wave-making resistance, the steady sinkage and trim, the lateral hydrodynamical force and the yawing moment were presented. The proposed method was justified by the numerical investigation. However, it is necessary to verify and to improve this method further.
GPU compute memory systems
Creators: name: Yuan, George Lai
Publisher: name: University of British Columbia
Year: 2009

description: Modern Graphic Process Units (GPUs) offer orders of magnitude more raw computing power than contemporary CPUs by using many simpler in-order single-instruction, multiple-data (SIMD) cores optimized for multi-thread performance rather than single-thread performance. As such, GPUs operate much closer to the "Memory Wall", thus requiring much more careful memory management. This thesis proposes changes to the memory system of our detailed GPU performance simulator, GPGPU-Sim, to allow proper simulation of general-purpose applications written using NVIDIA's Compute Unified Device Architecture (CUDA) framework. To test these changes, fourteen CUDA applications with varying degrees of memory intensity were collected. With these changes, we show that our simulator predicts performance of commodity GPU hardware with 86% correlation. Furthermore, we show that increasing chip resources to allow more threads to run concurrently does not necessarily increase performance due to increased contention for the shared memory system. Moreover, this thesis proposes a hybrid analytical DRAM performance model that uses memory address traces to predict the efficiency of a DRAM system when using a conventional First-Ready First-Come First-Serve (FR-FCFS) memory scheduling policy. To stress the proposed model, a massively multithreaded architecture based upon contemporary high-end GPUs is simulated to generate the memory address trace needed. The results show that the hybrid analytical model predicts DRAM efficiency to within 11.2% absolute error when arithmetically averaged across a memory-intensive subset of the CUDA applications introduced in the first part of this thesis. Finally, this thesis proposes a complexity-effective solution to memory scheduling that recovers most of the performance loss incurred by a naive in-order First-in First-out (FIFO) DRAM scheduler compared to an aggressive out-of-order FR-FCFS scheduler. While FR-FCFS scheduling re-orders memory requests to improve row access locality, we instead employ an interconnection network arbitration scheme that preserves the inherently high row access locality of memory request streams from individual "shader cores" and, in doing so, achieve DRAM efficiency and system performance close to that of FR-FCFS with a simpler design. We evaluate our interconnection network arbitration scheme using crossbar, ring, and mesh networks and show that, when coupled with a banked FIFO in-order scheduler, it obtains up to 91.0% of the performance obtainable with an out-of-order memory scheduler with eight-entry DRAM controller queues.

description: Parton distribution functions, which represent the flavor and spin structure of the nucleon, provide invaluable information in illuminating quantum chromodynamics in the confinement region. Among various processes that measure such parton distribution functions, semi-inclusive deep inelastic scattering is regarded as one of the golden channels to access transverse momentum dependent parton distribution functions, which provide a 3-D view of the nucleon structure in momentum space. The Jefferson Lab experiment E06-010 focuses on measuring the target single and double spin asymmetries in the 3He(e, e'pi+,-)X reaction with a transversely polarized 3He target in Hall A with a 5.89 GeV electron beam. A leading pion and the scattered electron are detected in coincidence by the left High-Resolution Spectrometer at 16\circ and the BigBite spectrometer at 30\circ beam right, respectively. The kinematic coverage concentrates in the valence quark region, x \sim0.1-0.4, at Q2 \sim 1-3 GeV2. The Collins and Sivers asymmetries of 3He and neutron are extracted. In this review, an overview of the experiment and the final results are presented. Furthermore, an upcoming 12-GeV program with a large acceptance solenoidal device and the future possibilities at an electron-ion collider are discussed.

Regulation of ATP-binding cassette transporter A1 in cholesteryl ester storage disease
Creators: name: Bilbey, Nicolas James
Publisher: name: University of British Columbia
Year: 2009

description: Previous studies from the Francis laboratory have determined that regulation of ABCA1 expression is impaired in the lysosomal cholesterol storage disorder Niemann-Pick type C (NPC) disease, the presumed reason for the low plasma HDL-cholesterol (HDL-C) levels found in the majority of NPC disease patients. Cholesteryl ester storage disease (CESD) is another lysosomal cholesterol storage disorder, resulting from deficiency in lysosomal acid lipase (LAL). CESD patients develop premature atherosclerosis, possibly related to their known low plasma HDL-C levels. We hypothesized that in CESD the reduced activity of LAL also leads to impaired ABCA1 regulation and HDL formation due to the decrease in release of unesterified cholesterol from lysosomes. Our results show that human CESD fibroblasts exhibit a blunted increase in ABCA1 mRNA and protein in response to addition of low density lipoprotein (LDL) to the medium when compared to normal human fibroblasts. Efflux of LDL-derived cholesterol radiolabel and mass to apolipoprotein A-I-containing medium was markedly reduced in CESD fibroblasts compared to normal fibroblasts. Cellular radiolabeled cholesteryl ester derived from LDL and total cell cholesteryl ester mass was increased in CESD compared to normal cells. Delivery of an adenovirus expressing full length human lysosomal acid lipase (Ad-hLAL) results in correction of LAL activity and an increase ABCA1 protein expression, as well as correction of cholesterol and phospholipid release to apoA-I and normalization of cholesteryl ester levels in the CESD fibroblasts. These accumulated results suggest ABCA1 expression is dependent on lysosomal acid lipase activity, and provide additional support for a major role of the lysosomal pool of unesterified cholesterol as a regulator of ABCA1 expression and HDL formation in humans.

description: We report the discovery of TrES-5, a massive hot Jupiter that transits the star GSC 03949-00967 every 1.48 days. From spectroscopy of the star we estimate a stellar effective temperature of$5171 +/- 36 K, and from high-precision B, R and I photometry of the transit we constrain the ratio of the semi-major axis and the stellar radius to be 6.07 +/- 0.14. We compare these values to model stellar isochrones to obtain a stellar mass of 0.893 +/- 0.024 solar masses. Based on this estimate and the photometric time series, we constrain the stellar radius to be 0.866 +/- 0.013 solar radii, and the planet radius to be 1.209 +/- 0.021 Jupiter radii. We model our radial-velocity data assuming a circular orbit and find a planetary mass of 1.778 +/- 0.063 Jupiter masses. Our radial-velocity observations rule out line-bisector variations that would indicate a specious detection resulting from a blend of an eclipsing binary system. TrES-5 orbits one of the faintest stars with transiting planets found to date from the ground and demonstrates that precise photometry and followup spectroscopy are possible, albeit challenging, even for such faint stars.

description: Let (X,D) be a dlt pair, where X is a normal projective variety. Let S denote the support of the rounddown of D, and K the canonical divisor of X. We show that any smooth family of canonically polarized varieties over X§is isotrivial if the divisor -(K+D) is ample. This result extends results of Viehweg-Zuo and Kebekus-Kovacs. To prove this result we show that any extremal ray of the moving cone is generated by a family of curves, and these curves are contracted after a certain run of the minimal model program. In the log Fano case, this generalizes a theorem by Araujo from the klt to the dlt case. In order to run the minimal model program, we have to switch to a Q-factorialization of X. As Q-factorializations are generally not unique, we use flops to pass from one Q-factorialization to another, proving the existence of a Q-factorialization suitable for our purposes.

Reflections on state nationalism in Chinese historical pedagogy : accounts of the Second Opium War in Chinese middle-school history textbooks from 1912 and 2007
Creators: name: Grover, Caroline
Publisher: name: University of British Columbia
Year: 2009

description: Scholars tend to assume the link between Chinese education and nationalism, without looking at the specific ways in which the connection is made. An assessment of the way in which the Second Opium War (1856-1860) is depicted in two Chinese middle-school history textbooks, one from 1912 and the other from 2007, illustrates how the historic event may be used to conjure nationalist responses to an event that brought China into a new world order of sovereign nation-states. Based on the research presented in this paper, it can be shown that since the founding of a public education system in 1902, the Chinese government — whether late imperial, nationalist, or communist — has used history textbooks to express a specifically “national” history that brings the Chinese together behind a strong state that portrays itself as the guardian of a nation’s sovereignty and cultural identity. This paper first assesses the importance of state legitimacy and the role of promoting a specific national narrative that supports the state’s authority in the creation of state-endorsed nationalism, then considers the role of the state in the establishment of a national education system and the production of history textbooks, and finishes with a comparison of passages about the Second Opium War in a textbook from 1912 and one from 2007. Whereas the 1912 passage reinforces the new Republic of China’s claim to legitimacy by focusing on the imperial government’s ineptitude at handling foreign incursion during the Second Opium War, completely overlooking the role of Western interests and aggression in China, the 2007 passage condenses the whole war to the looting and burning of the Yuanming Yuan in order to create a shared memory of humiliation that reminds students of the Chinese Communist Party’s historic victory over imperialism and that may impel Chinese youth to redress the problem of China’s inequality on the world stage. An analysis of the passages about the Second Opium War in these two textbooks demonstrates in a concrete way the role of teaching the country’s “imagined” past in inculcating a contemporary national identity that can then be used to legitimize those in power.

We found that submicron-thick membranes made from graphene oxide can be completely impermeable to liquids, vapors and gases, including helium, but allow unimpeded permeation of water (H2O permeates through the membranes at least 10^10 times faster than He). We attribute these seemingly incompatible observations to a low-friction flow of a monolayer of water through two dimensional capillaries formed by closely spaced graphene sheets. Diffusion of other molecules is blocked by reversible narrowing of the capillaries in low humidity and/or by their clogging with water.

description: Using generic properties of Clifford algebras in any spatial dimension, we explicitly classify Dirac hamiltonians with zero modes protected by the discrete symmetries of time-reversal, particle-hole symmetry, and chirality. Assuming the boundary states of topological insulators are Dirac fermions, we thereby holographically reproduce the Periodic Table of topological insulators found by Kitaev and Ryu. et. al, without using topological invariants nor K-theory. In addition we find candidate Z_2 topological insulators in classes AI, AII in dimensions 0,4 mod 8 and in classes C, D in dimensions 2,6 mod 8.

description: In 2005, Berenstein and Vazquez determined an open spin chain Hamiltonian describing the one-loop anomalous dimensions of determinant-like operators corresponding to open strings attached to Y=0 maximal giant gravitons. We construct the transfer matrix (generating functional of conserved quantities) containing this Hamiltonian, thereby directly proving its integrability. We find the eigenvalues of this transfer matrix and the corresponding Bethe equations, which we compare with proposed all-loop Bethe equations. We note that the Bethe ansatz solution has a certain "gauge" freedom, and is not completely unique.

description: Logistikansiedlungen können einen großen Flächenbedarf und erhebliche Verkehrswirkungen aufweisen und sollten daher in den Fokus der Regionalplanung rücken. Die Arbeit beinhaltet empirische Planungsgrundlagen in Form von Nutzungs- und Verkehrskennwerten für Logistikbetriebe und Standard-Typen der Logistikflächennutzung. Darauf aufbauend wird eine Verkehrswirkungsabschätzung von Logistik- Potenzialflächen und ihre exemplarische Anwendung auf die Logistikflächenentwicklung in der Metropolregion Hamburg dargestellt. Die erarbeiteten Grundlagen und Methoden können in der Regional- und Verkehrsplanung Tätige bei der Beurteilung von Logistikgebieten unterstützen. Insbesondere die Aussagen zu Flächen- und Verkehrsanforderungen von Logistikbetrieben dürften auch für Investoren und Immobilienentwickler von großem Interesse sein.
description: Due to their traffic impacts and land requirements the development of new logistics areas needs to be integrated into regional planning. A traffic impact assessment for comparing development sites is presented. It is based on different types of logistics land use and general trip generation rates derived from empirical analyses. Several development scenarios for new areas dedicated to logistics land use in the Hamburg region are evaluated.
Making noise : the transnational politics of Aceh and East Timor in the diaspora
Creators: name: Fallon, Karla S.
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation analyzes the transnational politics of two new or incipient diasporas, the Acehnese and East Timorese. It examines their political roles and activities in and across several countries in the West (Europe, North America, and Australia) as well as their impact on the “homeland” or country of origin, during and after armed conflict. It suggests that the importance of diaspora participation in conflict and conflict settlement is not solely or even primarily dependent on the material resources of the diaspora. Instead it is the ideational and political resources that may determine a diaspora’s ability to ensure its impact on the homeland, on the conflict, and its participation in the conflict settlement process. This study adopts a constructivist approach, process-tracing methods, and an analytical framework that combines insights from diaspora politics and theories on transnational advocacy networks (TANs). It concludes that the Aceh and East Timor cases support the proposition that diasporas are important and dynamic political actors, even when they are small, new, and weak. These cases also support the proposition that the political identities and goals of diasporas can be transformed over time as a diaspora is replenished with new members who have new or different ideas, as factions within diasporas gain power vis-à-vis others, and/or as the political partners available to the diaspora in the hostland and internationally change or broaden. The analysis of a diaspora’s relationship with a transnational advocacy network or networks (TAN) yields new insights into conflict settlement processes. Diasporans potentially learn from, contribute to, and benefit from TAN strategies and tactics. The TAN itself can help project the political influence of the diaspora. More significantly, the diaspora TAN relationship, in certain cases, can have a transformative effect on the diaspora, potentially moderating its views and positions, and thereby facilitating conflict settlement. Moreover, the moderating influence of the diaspora-TAN relationship may have implications for the post-conflict consolidation of democracy, human rights norms, and civil society.
Lithium abundances along the RGB: FLAMES-GIRAFFE spectra of a large sample of low-mass Bulge stars

description: Context: A small number of K-type giants on the red giant branch (RGB) is known to be very rich in lithium (Li). This fact is not accounted for by standard stellar evolution theory. The exact phase and mechanism of Li enrichment is still a matter of debate. Aims: Our goal is to probe the abundance of Li along the RGB, from its base to the tip, to confine Li-rich phases that are supposed to occur on the RGB. Methods: For this end, we obtained medium-resolution spectra with the FLAMES spectrograph at the VLT in GIRAFFE mode for a large sample of 401 low-mass RGB stars located in the Galactic bulge. The Li abundance was measured in the stars with a detectable Li 670.8 nm line by means of spectral synthesis with COMARCS model atmospheres. A new 2MASS (J-K) - Teff calibration from COMARCS models is presented in the Appendix. Results: Thirty-one stars with a detectable Li line were identified, three of which are Li-rich according to the usual criterion ($\logε({\rm Li})>1.5$). The stars are distributed all along the RGB, not concentrated in any particular phase of the red giant evolution (e.g. the luminosity bump or the red clump). The three Li-rich stars are clearly brighter than the luminosity bump and red clump, and do not show any signs of enhanced mass loss. Conclusions: We conclude that the Li enrichment mechanism cannot be restricted to a clearly defined phase of the RGB evolution of low-mass stars ($M\sim1M_{\sun}$), contrary to earlier suggestions from disk field stars.

The results in both cases {\em viz.} a sharp increase in B(E2) values at very low spins, may be interpreted as resulting from a mixing between two bands of different quadrupole deformations.

Places for the good care of children : a discussion of indigenous cultural considerations and early childhood in Canada and New Zealand
Creators: name: Greenwood, Margo Lainne
Publisher: name: University of British Columbia
Year: 2009

description: Places for the Good Care of Children is, broadly speaking, about Indigenous early childhood and the potential of understanding child development as a site for cultural rejuvenation and efforts to rebuild colonized peoples. More specifically, the project seeks to answer questions about linkages between early childhood, government policies, community visions, and the identity and rebuilding of Indigenous peoples and communities. I pursue this topic by examining two communities (Lake Babine and Tl'azt'en) within the Carrier Nation in Canada and two Tuhoe Maori Kohanga Reo sites in Aotearoa / New Zealand. Integral to this study is my own positioning as a Cree scholar, a long-time professional in the area of early childhood development, an advisor on multiple committees and tables concerned with Aboriginal issues in Canada, and a mother of three. From these multiple positions I have undertaken a qualitative inquiry employing focus groups, key informant interviews, and thematic analysis, all of which draw from multiple methodologies and a literature largely comprising works concerned with decolonization, Indigenous theory, early childhood development, and policy. The key findings of this research suggest that early childhood (and related educational considerations) is a critical site for cultural rejuvenation, for the rebuilding of community, and for the establishment of healthy Aboriginal communities in the future. Fundamental to this (rebuilding is autonomy by Indigenous communities over language and culture, over the care and education of their children, over their lives and futures, and over the lives and futures of their children.
