description: Many classical encoding algorithms of Vector Quantization (VQ) of image compression that can obtain global optimal solution have computational complexity O(N). A pure quantum VQ encoding algorithm with probability of success near 100% has been proposed, that performs operations 45sqrt(N) times approximately. In this paper, a hybrid quantum VQ encoding algorithm between classical method and quantum algorithm is presented. The number of its operations is less than sqrt(N) for most images, and it is more efficient than the pure quantum algorithm.

description: With infrared spectroscopy we studied the bulk electronic properties of the topological antiferromagnet MnBi$_2$Te$_4$ with $T_N \simeq 25~\mathrm{K}$. With the support of band structure calculations, we assign the intra- and interband excitations and determine the band gap of $E_g \approx$ 0.17 eV. We also obtain evidence for two types of conduction bands with light and very heavy carriers. The multiband free carrier response gives rise to an unusually strong increase of the combined plasma frequency, $ω_{\mathrm{pl}}$, below 300 K. The band reconstruction below $T_N$, yields an additional increase of $ω_{\mathrm{pl}}$ and a splitting of the transition between the two conduction bands by about 54 meV. Our study thus reveals a complex and strongly temperature dependent multi-band low-energy response that has important implications for the study of the surface states and device applications.

description: Optimal control problems are formulated and efficient computational procedures are proposed for combined orbital and rotational maneuvers of a rigid body in three dimensions. The rigid body is assumed to act under the influence of forces and moments that arise from a potential and from control forces and moments. The key features of this paper are its use of computational procedures that are guaranteed to preserve the geometry of the optimal solutions. The theoretical basis for the computational procedures is summarized, and examples of optimal spacecraft maneuvers are presented.

Subjects: subject: Computational Complexity (cs.CC)

description: The main goal of this paper is to put some known results in a common perspective and to simplify their proofs. We start with a simple proof of a result from (Vereshchagin, 2002) saying that $\limsup_n\KS(x|n)$ (here $\KS(x|n)$ is conditional (plain) Kolmogorov complexity of $x$ when $n$ is known) equals $\KS^{\mathbf{0'}(x)$, the plain Kolmogorov complexity with $\mathbf{0'$-oracle. Then we use the same argument to prove similar results for prefix complexity (and also improve results of (Muchnik, 1987) about limit frequencies), a priori probability on binary tree and measure of effectively open sets. As a by-product, we get a criterion of $\mathbf{0'}$ Martin-Löf randomness (called also 2-randomness) proved in (Miller, 2004): a sequence $ω$ is 2-random if and only if there exists $c$ such that any prefix $x$ of $ω$ is a prefix of some string $y$ such that $\KS(y)\ge |y|-c$. (In the 1960ies this property was suggested in (Kolmogorov, 1968) as one of possible randomness definitions; its equivalence to 2-randomness was shown in (Miller, 2004) while proving another 2-randomness criterion (see also (Nies et al. 2005)): $ω$ is 2-random if and only if $\KS(x)\ge |x|-c$ for some $c$ and infinitely many prefixes $x$ of $ω$. Finally, we show that the low-basis theorem can be used to get alternative proofs for these results and to improve the result about effectively open sets; this stronger version implies the 2-randomness criterion mentioned in the previous sentence.

description: We propose a two-component reaction-transport model for the migration-proliferation dichotomy in the spreading of tumor cells. By using a continuous time random walk (CTRW) we formulate a system of the balance equations for the cancer cells of two phenotypes with random switching between cell proliferation and migration. The transport process is formulated in terms of the CTRW with an arbitrary waiting time distribution law. Proliferation is modeled by a standard logistic growth. We apply hyperbolic scaling and Hamilton-Jacobi formalism to determine the overall rate of tumor cell invasion. In particular, we take into account both normal diffusion and anomalous transport (subdiffusion) in order to show that the standard diffusion approximation for migration leads to overestimation of the overall cancer spreading rate.

title: Meta-narrative or micro-history: a census-based study of domestic service in Edwardian rural Berkshire
Creators: name: Jolly, Peter
Publisher: name: University of Reading
Year: 2023

description: This thesis uses a largely quantitative approach to position female domestic servants 
within Berkshire village and market town life at the beginning of the twentieth century. 
Previous demographically based studies, using the only available census material and 
often focussing on larger Victorian urban communities, addressed neither rural 
domestic servants nor concentrated on the years immediately before the outbreak of war 
when service remained the commonest female occupation. My work aimed to populate 
this void, concentrating scrutiny on 1911 census returns for rural areas and smaller 
towns. 
Analyses of census schedules for nearly 1,200 servants addressed five distinct but 
interlocking threads, collectively illuminating the essential characteristics of 
contemporary Berkshire domestic service. These covered the home backgrounds of 
Berkshire servants, migratory trends within the servant community, the internal 
structure of the servant economy, the composition of households employing residential 
servants, and employment opportunities for young women outside service. Subsidiary 
aspects included comparing sample communities from a generation previously, using 
censuses to track employment patterns amongst younger servants, and assessing the 
extent of alleged servant shortages. 
The thesis found little statistical evidence to support claims of a widespread servant 
problem. Service was an integral feature of community life with limited alternative 
employment opportunities for rural girls. Young domestics tended initially to remain 
local before moving away. Distinct variations in patterns of service county-wide, such
as the many single-servant homes in the west of the county, reflected wider socio-economic community structures. The dynamics of specific master-servant relationships 
were, despite domestic servants being almost exclusively female, governed more by 
class than gender. 
Notwithstanding limitations in using raw data from decennial censuses, this study 
shows the importance of local studies in social history. Many findings supported known 
trends and endorsed existing research, bolstering their value, whilst others challenged 
generalities derived from research on conceptually different communities.

 EXAMINED MATERIAL. — 1049 bone elements corresponding to broken trunk vertebrae, cervical vertebrae, and post-cloacal vertebrae are attributed to the genus Alsophis on the basis of their size and overall morphology.
REMARKS
 The morphology of cervical and post-cloacal vertebrae was not deeply studied in the framework of this study which precludes a specific identification. These elements were associated to Alsophis mainly on the basis that it was possible to confidently assume they belong to a colubrid snake larger than Erythrolamprus and presenting no strong difference with our modern specimens of Alsophis.

description: From Very Long Baseline Array (VLBA) observations we previously identified a population of 123 young stellar systems with nonthermal radio emission toward the core of the Orion Nebula Cluster (ONC). We find optical sources in the Gaia DR2 catalog for 34 of them within 0.2" of the radio positions. Most of the radio sources are likely companions of Gaia detections. However, there are 11 stars whose VLBA position differs from Gaia by $<1.6$ mas, and some of these radio sources probably are the direct counterparts of the optical stars. We are able to obtain radio proper motions for 23 stars. Combining the stellar proper motions derived from the VLBA and Gaia data we find the global motion and velocity dispersion of the ONC to be ($μ_α*,μ_δ$)=($1.20\pm0.09,0.18\pm0.09$) mas yr$^{-1}$ and ($σ_{μ_α*},σ_{μ_δ}$)=($0.84\pm0.09,1.30\pm0.09$) mas yr$^{-1}$. Finally, we looked for ordered motions by estimating the means of scalar and vectorial products, which results in $\mathbf{\overline{v\cdot\hat{r}}}=-0.61\pm1.00$ km s$^{-1}$ and $\mathbf{\overline{v\times\hat{r}}}=0.57\pm0.95$ km s$^{-1}$. These do not show indications that the young stellar cluster is in expansion, contraction, or rotation.

description: We outline a perspective of an entirely new research branch in Earth and climate sciences, where deep neural networks and Earth system models are dismantled as individual methodological approaches and reassembled as learning, self-validating, and interpretable Earth system model-network hybrids. Following this path, we coin the term "Neural Earth System Modelling" (NESYM) and highlight the necessity of a transdisciplinary discussion platform, bringing together Earth and climate scientists, big data analysts, and AI experts. We examine the concurrent potential and pitfalls of Neural Earth System Modelling and discuss the open question whether artificial intelligence will not only infuse Earth system modelling, but ultimately render them obsolete.

description: A deterministic attitude estimation problem for a rigid body in an attitude dependent potential field with bounded measurement errors is studied. An attitude estimation scheme that does not use generalized coordinate representations of the attitude is presented here. Assuming that the initial attitude, angular velocity and measurement noise lie within given ellipsoidal bounds, an uncertainty ellipsoid that bounds the attitude and the angular velocity of the rigid body is obtained. The center of the uncertainty ellipsoid provides point estimates, and its size gives the accuracy of the estimates. The point estimates and the uncertainty ellipsoids are propagated using a Lie group variational integrator and its linearization, respectively. The estimation scheme is optimal in the sense that the attitude estimation error and the size of the uncertainty ellipsoid is minimized at each measurement instant, and it is global since the attitude is represented by a rotation matrix.

Shock wave as a probe of flux-limited thermal transport in laser-heated solids
Creators: name: Smith, Kristin A.
Publisher: name: University of British Columbia
Year: 2009

description: Classical Spitzer-Harm treatment of electron thermal conduction breaks down in the steep temperature gradients found in laser-heated solids. A phenomenological flux-limiter, which reduces heat flow, is incorporated into computer codes which model laser-target interactions. There is disagreement in what the correct value of the flux-limiter, ∫, should be. A simple method to determine the best value is presented. It involves comparing experimental shock speed data with predicted values for the range of possible values of ∫, i.e. between 0.03 and 0.6, where 0.6 represents the free-streaming limit. Three different laser intensity regimes are investigated (2x10¹³, 2 x 10¹⁴, and 1 x 10¹⁵ W/cm²) using a trapezoidal (100 ps rise and fall times, 400 ps flat top) 0.532 μm laser pulse. Two laser absorption models are also compared: the traditional inverse bremsstrahlung (IB) absorption and an electromagnetic wave solver (EMS). The first calculates the local absorption factor, ⍺, as the laser light penetrates into the target, and requires a free parameter to start the simulation. This parameter legislates a fraction of the penetrating laser energy to be deposited at the critical density surface. The second method solves the time evolution of the Helmholtz equations for electromagnetic waves in an inhomogeneous dielectric. It is shown that the predicted shock speed is sensitive to ∫ in the range 0.03≲∫≲0.08 at 2x10¹⁵ W/cm², and 0.03≲∫≲0.15 at 1x10¹⁵ W/cm². A shock speed of (3x10⁶±5%) cm/s is predicted using the EMS method and laser irradiance of (2x10¹⁴ ± 10%) W/cm² with ∫≃0.090[sup +0.095]/[sub -0.022]. The IB method does not give a unique solution. The same irradiance gives the required speed with ∫≃[sup +0.006]/[sub -0.007] assuming 1% energy dump at the critical density, and with ∫≃0.03 assuming 10% dump. For this reason, the EMS method is preferred.

description: We investigate the burstiness of star formation and the ionizing efficiency of a large sample of galaxies at $0.7 < z < 1.5$ using HST grism spectroscopy and deep ultraviolet (UV) imaging in the GOODS-N and GOODS-S fields. The star formation history (SFH) in these strong emission line low-mass galaxies indicates an elevated star formation rate (SFR) based on the H$α$ emission line at a given stellar mass when compared to the standard main sequence. Moreover, when comparing the H$α$ and UV SFR indicators, we find that an excess in SFR(H$α$) compared to SFR(UV) is preferentially observed in lower-mass galaxies below $10^{9}$ M$\odot$, which are also the highest-EW galaxies. These findings suggest that the burstiness parameters of these strong emission line galaxies may differ from those inferred from hydrodynamical simulations and previous observations. For instance, a larger burstiness duty cycle would explain the observed SFR(H$α$) excess. We also estimate the ionizing photon production efficiency $ξ_{ion}$, finding a median value of Log($ξ_{ion}$/erg$^{-1}$ Hz)$=24.80 \pm 0.26$ when adopting a Galactic dust correction for H$α$ and an SMC one for the stellar component. We observe an increase of $ξ_{ion}$ with redshift, further confirming similar results at higher redshifts. We also find that $ξ_{ion}$ is strongly correlated with EW(H$α$), which provides an approach for deriving $ξ_{ion}$ in early galaxies. Lower-mass, lower-luminosity galaxies have a higher $ξ_{ion}$. Overall, these results provide further support for faint galaxies playing a major role in the reionization of the Universe.

description: We study ways to expedite Yates's algorithm for computing the zeta and Moebius transforms of a function defined on the subset lattice. We develop a trimmed variant of Moebius inversion that proceeds point by point, finishing the calculation at a subset before considering its supersets. For an $n$-element universe $U$ and a family $\scr F$ of its subsets, trimmed Moebius inversion allows us to compute the number of packings, coverings, and partitions of $U$ with $k$ sets from $\scr F$ in time within a polynomial factor (in $n$) of the number of supersets of the members of $\scr F$. Relying on an intersection theorem of Chung et al. (1986) to bound the sizes of set families, we apply these ideas to well-studied combinatorial optimisation problems on graphs of maximum degree $Δ$. In particular, we show how to compute the Domatic Number in time within a polynomial factor of $(2^{Δ+1-2)^{n/(Δ+1)$ and the Chromatic Number in time within a polynomial factor of $(2^{Δ+1-Δ-1)^{n/(Δ+1)$. For any constant $Δ$, these bounds are $O\bigl((2-ε)^n\bigr)$ for $ε>0$ independent of the number of vertices $n$.

description: The $Gaia$ mission has provided an unprecedented wealth of information about the white dwarf population of our Galaxy. In particular, our studies show that the sample up to 100\,pc from the Sun can be considered as practically complete. This fact allows us to estimate a precise fraction of double-degenerate ($1.18\pm 0.10$\%) and white dwarf plus main-sequence stars ($6.31\pm0.23$\%) among all white dwarfs through comoving pairs identification. With the aid of a detailed population synthesis code we are able to reproduce synthetic white dwarf populations with nearly identical fractions as the observed ones, thus obtaining valuable information about the binary fraction, $f_{\rm b}$, initial mass ratio distribution, $n(q)$, and initial separation distribution, $f(a)$, among other parameters. Our best-fit model is achieved within a $1σ$ confidence level for $f(a)\propto a^{-1}$, $n(q)\propto q^{n_q}$, with $n_q=-1.13^{+0.12}_{-0.10}$ and $f_{\rm b}=0.32\pm 0.02$. The fraction of white dwarf mergers generated by this model is $9\sim16\%$, depending on the common-envelope treatment. As sub-products of our modelling we find that around $1\sim3\%$ of the white dwarf population are unresolved double-degenerates and that only $\sim1\%$ of all white dwarfs contain a He-core. Finally, only a mild kick during white dwarf formation seems to be necessary for fitting the observed sky separation of double-degenerate systems.

Even though these reactions are dominated by intermediate states with excited kaons, we are able to study for the first time the cross section for $e^+ e^- \to ϕ(1020) f_{0}(980)$ as a function of center-of-mass energy. We observe a structure near threshold consistent with a $1^{--}$ resonance with mass $m = 2.175 \pm 0.010\pm 0.015 GeV/c^2$ and width $Γ= 58\pm 16\pm 20 MeV$. We observe no Y(4260) signal and set a limit of $BR_{Y\toϕπ^+π^-}\cdotΓ^{Y}_{ee}<0.4$ eV (90% confidence level), which excludes some models.

We observe signatures of strong electron-electron interactions: the conductance exhibits bias-voltage-dependent amplitudes of quantum interference oscillation, and both the current noise and Fano factor manifest bias-voltage-dependent power-law scalings. We analyze our data within the Tomonaga-Luttinger liquid model using the non-equilibrium Keldysh formalism and find qualitative and quantitative agreement between experiment and theory.

description: Electronic excitations and ionisations produced by electron impact are key processes in the radiation-induced damage mechanisms in materials of biological relevance, underlying important medical and technological applications, including radiotherapy, radiation protection in manned space missions and nanodevice fabrication techniques. However, experimentally measuring all the necessary electronic interaction cross-sections for every relevant material is an arduous task, so it is necessary having predictive models, sufficiently accurate yet easily implementable. In this work we present a model, based on the dielectric formalism, to provide reliable ionisation and excitation cross-sections for electron-impact on complex biomolecular media, taking into account their condensed-phase nature. We account for the indistinguishability and exchange between the primary beam and excited electrons, for the molecular electronic structure effects in the electron binding, as well as for higher-order corrections to the first Born approximation. The resulting approach yields total ionisation cross-sections, energy distributions of secondary electrons, and total electronic excitation cross-sections for condensed-phase biomaterials, once the electronic excitation spectrum is known, either from experiments or from a predictive model. The results of this methodology are compared with the available experimental data in water and DNA/RNA molecular building blocks, showing a very good agreement and a great predictive power in a wide range of electron incident energies, from the large values characteristic of electron beams down to excitation threshold. The proposed model constitutes a very useful procedure for computing the electronic interaction cross-sections for arbitrary biological materials in a wide range of electron incident energies.

description: We use Shelah's theory of possible cofinalities in order to solve a problem about ultrafilters. THEOREM. Suppose that $ λ$ is a singular cardinal, $ λ' < λ$, and the ultrafilter $D$ is $ κ$-decomposable for all regular cardinals $ κ$ with $ λ' < κ< λ$. Then $D$ is either $ λ$-decomposable, or $ λ^+$-decomposable. We give applications to topological spaces and to abstract logics.

title: Investigating the role of the GABA/ glutamate system in the mammalian kidney
Creators: name: Dunn, Kadeshia
Publisher: name: University of Kent
Year: 2015

description: GABA is a well established inhibitory neurotransmitter in the CNS, which has an opposing role to its precursor, glutamate, which is an excitatory neurotransmitter. In the CNS, both GABA and glutamate have multifunctional roles that are essential for normal brain functioning, which includes the regulation of cerebral blood flow. Both GABA and glutamate have been shown to induce pericyte-mediated changes in blood flow in the retinae and in the cerebellum, respectively. Pericytes are expressed throughout all mammalian tissue including the kidney, and they are renowned for their contractile nature and their ability to modulate capillary diameter. An increasing number of publications have suggested that both GABA and glutamate might also play a role in the regulation of renal function. All key enzymes associated with GABA/ glutamate metabolism have been localised to the kidney providing the necessary machinery for localised GABA/ glutamate synthesis and metabolism. Despite the collective evidence describing the presence of a GABA/ glutamate system in the kidney, the precise function of such a system requires further clarification. The work presented in this thesis is principally concerned with establishing the physiological role(s) of the GABA and glutamate system in the kidney. This thesis seeks to address this question using a live kidney slice model to investigate pericyte-mediated real-time changes in vasa recta diameter in response to GABA, glutamate and associated compounds. Confocal microscopy techniques were used to confirm the expression of key components in the GABA shunt pathway, in relation to the renal medulla. Data presented here, highlights a novel role for both GABA and glutamate, expressed in both vascular and tubular compartments in the renal medulla, to induce pericyte- mediated regulation of vasa recta diameter, and therefore medullary blood flow. The second aspect of this thesis focuses on determining whether functional GABA receptors exist within renal tissue, focusing specifically on their expression within the cortical collecting duct. Electrophysiological experimental data highlights that functional GABA receptors exist in a renal cell line, which serves to modulate solute transport. In conclusion, this thesis highlights that GABA is able to modulate both vascular and tubular aspects of renal function. While, glutamate, and its co- agonist, glycine, have an opposing effect to GABA, and serve to induce vasodilation. The results of this work highlight new key players that affect renal function, which may be significant in both health and disease.

description: We show that the blazar PKS 1424+240, which has been recently associated by IceCube with a neutrino excess at the $3.3\,σ$ level together with three other sources, is similar to the first plausible non-stellar neutrino source, TXS 0506+056, in being also a masquerading BL Lac object, i.e., intrinsically a flat-spectrum radio quasar with hidden broad lines and a standard accretion disk. We point out that these two sources share other properties, including spectral energy distribution, high powers, parsec scale properties, and possibly radio morphology. We speculate that the relatively rare combination of proton-loaded jets, possibly typical of high-excitation sources, and efficient particle acceleration processes, related to their relatively high synchrotron peak frequencies, might favour neutrino production in these two sources. GB6 J1542+6129, which has also recently appeared twice in a list of IceCube associations, seems also to belong to this rare blazar sub-class, which includes at most ~ 20 Fermi-4LAC blazars.

description: The temperature dependence of saturation and spin-flop fields for artificial ferrimagnets (AFi) based on antiparallel coupled CoFeB/Ru/CoFeB trilayers has been investigated in a temperature range between 80K and 600K. The results presented in this paper are relevant for magnetic devices using this system, e.g. magnetic-random access memory based on spin-flop switching. In good accordance to the theory, the saturation field Hsat behaves like Hsat ~ H_0 (T/T_0)/sinh(T/T_0) with a characteristic temperature of T_0 = 150K. Within this model, the Fermi velocity for the Ru layer is of the order of 10^5m/s, therefore, explaining the strong variation of the coupling strength with the temperature in Ru based AFi. Furthermore, a strong uniaxial anisotropy of K_u = 2x10^3 J/m^3 with a small angular distribution of the anisotropy axes is observed for the AFi trilayers based on amorphous CoFeB alloys.

Experiments on Pro-Sociality and Environmental Issues

Year: 2015
Subjects: SECS-P/01 Economia politica

description: The thesis comprises three essays that use experimental methods, one about other-regarding motivations in economic behavior and the others on pro-social behavior in two environmental economics problems. 
The first chapter studies how the expectations of the others and the concern to maintain a balance between effort exerted and rewards obtained interact in shaping the behavior in a modified dictator game. We find that dictators condition their choices on recipients' expectations only when there is a high probability that the the recipient will not be compensated for her effort. Otherwise, dictators tend to balance the efforts and rewards of the recipients, irrespective of the recipients' expectations.  
In the second chapter, I investigate the problem of local opposition to large public projects (e.g. landfills, incinerators, etc.). In particular, the experiment shows how the uncertainty about the project's quality makes the community living in the host site skeptical about the project. I also test whether side-transfers and costly information disclosure can help to increase the efficiency. Both tools succesfully make the host more willing to accept the project, but they lead to the realization of different types of projects. 
The last chapter is an experiment on climate negotiations. To avoid the global warming, countries are called to cooperate in the abatement of their emissions. We study whether the dynamic aspect of the climate change makes cooperation across countries behaviorally more difficult. We also consider inequality across countries as a possible factor that hinders international cooperation.

description: Deep learning demonstrated major abilities in solving many kinds of different real-world problems in computer vision literature. However, they are still strained by simple reasoning tasks that humans consider easy to solve. In this work, we probe current state-of-the-art convolutional neural networks on a difficult set of tasks known as the same-different problems. All the problems require the same prerequisite to be solved correctly: understanding if two random shapes inside the same image are the same or not. With the experiments carried out in this work, we demonstrate that residual connections, and more generally the skip connections, seem to have only a marginal impact on the learning of the proposed problems. In particular, we experiment with DenseNets, and we examine the contribution of residual and recurrent connections in already tested architectures, ResNet-18, and CorNet-S respectively. Our experiments show that older feed-forward networks, AlexNet and VGG, are almost unable to learn the proposed problems, except in some specific scenarios. We show that recently introduced architectures can converge even in the cases where the important parts of their architecture are removed. We finally carry out some zero-shot generalization tests, and we discover that in these scenarios residual and recurrent connections can have a stronger impact on the overall test accuracy. On four difficult problems from the SVRT dataset, we can reach state-of-the-art results with respect to the previous approaches, obtaining super-human performances on three of the four problems.

Unsolvability of the Halting Problem in Quantum Dynamics

description: It is shown that the halting problem cannot be solved consistently in both the Schrodinger and Heisenberg pictures of quantum dynamics. The existence of the halting machine, which is assumed from quantum theory, leads into a contradiction when we consider the case when the observer's reference frame is the system that is to be evolved in both pictures. We then show that in order to include the evolution of observer's reference frame in a physically sensible way, the Heisenberg picture with time going backwards yields a correct description.

The obtained spectroscopic [OI]63mum and [OI]145mum maps enable us to study the spatial extent of warm, low-excitation atomic gas within outflows driven by Class I protostars. These [OI] maps may potentially allow us to measure the mass-loss rates ($\dot{M}_\text{jet}$) of this warm component of the atomic jet.

description: We present a method for applying spatially resolved adiabatic and radiative loss processes to synthetic radio emission from hydrodynamic simulations of radio sources from active galactic nuclei (AGN). Lagrangian tracer particles, each representing an ensemble of electrons, are injected into simulations and the position, grid pressure, and time since the last strong shock are recorded. These quantities are used to track the losses of the electron packet through the radio source in a manner similar to the Radio AGN in Semi-analytic Environments (RAiSE) formalism, which uses global source properties to calculate the emissivity of each particle ex-situ. Freedom in the choice of observing parameters, including redshift, is provided through the post-processing nature of this approach. We apply this framework to simulations of jets in different environments, including asymmetric ones. We find a strong dependence of radio source properties on frequency and redshift, in good agreement with observations and previous modelling work. There is a strong evolution of radio spectra with redshift due to the more prominent inverse-Compton losses at high redshift. Radio sources in denser environments have flatter spectral indices, suggesting that spectral index asymmetry may be a useful environment tracer. We simulate intermediate Mach number jets that disrupt before reaching the tip of the lobe, and find that these retain an edge-brightened Fanaroff-Riley Type II morphology, with the most prominent emission remaining near the tip of the lobes for all environments and redshifts we study.

Unlocking the gate : teaching for transformation as pedagogical artists
Creators: name: Robertson, Helen
Publisher: name: University of British Columbia
Year: 2009

description: This research argues in favour of a transformational orientation to art education curriculum.. I discuss implementing a teacher-as-artist model in art education as a means to achieve personal transformation. I examine the practices of three art teachers who engage in creating art work themselves as a way of modeling art production and visual problem solving with students, in an effort to facilitate student transformation. As a participant in this process, I retell my own experiences as an artist and teacher, and thus my own personal transformations are identified. Achieving a transformational orientation is not easy and as such, complexities and tensions are identified while sharing authority and leadership in a collaborative way. An action research methodology was chosen as a way to systematically investigate the feminist principles of cooperation, collaboration, and honouring lived experiences which form the pedagogical structures that support teaching in a transformational orientation. However, as the research unfolded, the methodology itself transformed to include my own autobiography. The findings of this study point to the themes of identity, commitment and relationships as indicators of teachers respecting a transformational pedagogy. The research concludes with the original model of teacher-as-artist evolving to a concept of the role of pedagogical artists, as teacher/student relationships are altered to become more caring, trusting, and respectful. Therein lies the possibility for personal change, thus moving us in a direction towards a societal transformation.
