Critical duration, contrast sensitivity, and specific reading disability
Creators: name: Blackwood, Mary Heather
Publisher: name: University Of Tasmania
Year: 2023

description: Critical durations and contrast sensitivities for sine-wave gratings of four different spatial frequencies - were measured in normal and disabled readers. Two groups, each of ten subjects, with an average age of 14 years, and matched as to seZ age; IQ, and socio‚ÄövÑvÆeconomic status, were used. The results showed that while critical duration for controls increases significantly with spatial frequency, this is not so for disabled readers, suggesting that the two groups may differ in terms of the temporal properties of their spatial frequency channels. It Was also found, for stimulus durations approximately equal to fixation durations, that disabled readers were relatively less sensitive than were controls at low to medium spatial frequencies. At all duration's there was a marked contrast sensitivity loss at 4 c/deg. Controls, in respect of both critical duration and contrast sensitivity function, produced results similar to those found in other studies on normal adult subjects. The suggestion of spatial frequency-selective differences in critical duration and the clear finding of such differences in contrast sensitivity may indicate a fundamental abnormality in the visual-temporal integration of spatial Stimuli. The existence of such qualitative differences in children at this comparatively mature age renders a developmental explanation unlikely. An explanation discounting visual perceptual differences seems even more untenable. The present study does not preclude a multi-factorial etiology for SRD; it does; however, indicate that abnormality .in spatial - frequency-specific channels of visual information processing is one factor which can now confidently be included.

Year: 2008
Subjects: subject: Logic in Computer Science (cs.LO)
subject: FOS: Computer and information sciences

description: interpreters are tools to compute approximations for behaviors of a program. These approximations can then be used for optimisation or for error detection. In this paper, we show how to describe an abstract interpreter using the type-theory based theorem prover Coq, using inductive types for syntax and structural recursive programming for the abstract interpreter's kernel. The abstract interpreter can then be proved correct with respect to a Hoare logic for the programming language.

description: We consider the Fuchsian linear differential equation obtained (modulo a prime) for $\tildeχ^{(5)}$, the five-particle contribution to the susceptibility of the square lattice Ising model. We show that one can understand the factorization of the corresponding linear differential operator from calculations using just a single prime. A particular linear combination of $\tildeχ^{(1)}$ and $\tildeχ^{(3)}$ can be removed from $\tildeχ^{(5)}$ and the resulting series is annihilated by a high order globally nilpotent linear ODE. The corresponding (minimal order) linear differential operator, of order 29, splits into factors of small orders. A fifth order linear differential operator occurs as the left-most factor of the "depleted" differential operator and it is shown to be equivalent to the symmetric fourth power of $L_E$, the linear differential operator corresponding to the elliptic integral $E$. This result generalizes what we have found for the lower order terms $\tildeχ^{(3)}$ and $\tildeχ^{(4)}$. We conjecture that a linear differential operator equivalent to a symmetric $(n-1)$-th power of $L_E$ occurs as a left-most factor in the minimal order linear differential operators for all $\tildeχ^{(n)}$'s.

description: In this paper we consider flat metrics (semi-translation structures) on surfaces of finite type. There are two main results. The first is a complete description of when a set of simple closed curves is spectrally rigid, that is, when the length vector determines a metric among the class of flat metrics. Secondly, we give an embedding into the space of geodesic currents and use this to get a boundary for the space of flat metrics. The geometric interpretation is that flat metrics degenerate to "mixed structures" on the surface: part flat metric and part measured foliation.

On the Japanese passive form
Creators: name: Ogawa, Nobuo
Publisher: name: University of British Columbia
Year: 2011

description: The Japanese passive voice is quite different from that of English. This thesis is an attempt to investigate the nature of the passive form in Japanese in contrast to the English passive voice and to examine the reasons for the differences. An examination is made of the English passive voice, followed by a contrastive analysis of Japanese transitive-intransitive verbs. Results of the investigation show that to some extent, the usage of Japanese intransitive verbs resembles the passive voice in English. There are three chapters in this thesis. The first chapter deals with an historical discussion of the European passive voice, from the notions of the Greek grammarians to the theories of the transformationalists. Japanese traditional grammar is the subject of the second chapter. The gradual development of the discussion of verbs by Japanese grammarians is outlined. Also, the nature of transitive-intransitive verbs is dealt with and an extensive, though not exhaustive, list of root-related transitive-intransitive verbs is presented. In the final chapter, discussions of the passive forms, by various grammarians are presented. Thereafter, the passive forms are examined by dividing them into two major groups: the ordinary form and the adverse passive form. Each form is syntactically examined and illustrations from literary sources are included. Conclusions show that, semantically, the ordinary passive form is similar to the English passive voice, whereas, the adverse passive form indicates a strong emotional feeling. The romanization of Japanese examples is represented by using Kunrei-Shiki¹ except for the following: /shi/...si, /sha/...sya, /shu/...syu, /sho/...syo, /chi/…ti, /tsu/...tu, /cha/…tya, /chu/…tyu, /cho/...tyo, /ji/...zi These latter symbols represent the verbal and adjectival conjugations much easier than the ordinary Kunrei-Shiki. Syllabic /n/ is represented as N to avoid confusion between such morphemes /tani/ (valley) and /tan'i/ (credit), which are shown as tani and taNi, respectively. These symbols are only used for the examples in the text; Kunrei-Shiki is used for references. English translations of Japanese quotations are mine.

We show results and numerically evaluate their impact on the neutralino annihilation cross section and the relic density in scenarios with non-universal gaugino masses. By comparing to the relic density obtained from a pure leading order calculation, we demonstrate that the corrections strongly influence the extraction of SUSY mass parameters from cosmological data.

Environmental features influencing the non-reproductive distribution and success of riverine populations of Salmo trutta Linnaeus (brown trout) : a review of the literature.
Creators: name: Andrew, J.
Publisher: name: University Of Tasmania
Year: 2023

description: Abstract taken from part of the introduction: Despite past controversy, it is now agreed that there is one species of trout native to north-western Europe - Salmo trutta. As the ice retreated at the end of the last ice age the rivers of northern Europe were colonised via the sea by two successive forms of trout. Both of these forms gave rise to brown trout which lived wholly in fresh water. Some of their modern descendants migrate to the sea but no consistent morphological criteria have been found to distinguish sea-run from non-migratory brown trout. It is still common for sea-run trout to be called Salmo trutta trutta and freshwater brown trout to be called Salmo trutta fario (MacCrimmon and Marshall, 1968; LeCren, 1984). For the purposes of this review, both forms will be considered, but only in the freshwater resident phase. The brown trout (Salmo trutta Linnaeus) is native to the European coast of the Atlantic Ocean and to the coast of the Mediterranean Sea. Its natural distribution includes Iceland, the Scandinavian countries, northern Europe, Great Britain, the Mediterranean countries including northern Africa and the countries of the Middle East whose rivers drain into the Mediterranean Sea. The Caspian, Aral and Black Seas and their tributaries also contain natural populations of brown trout (MacCrimmon and Marshall, 1968). Stocking of waters around the world has taken place since 1852 and there are now self-sustaining populations of brown trout on all continents with the exception of Antarctica (MacCrirnmon, Marshall and Gots, 1970). Brown trout are now found in a wide range of lotic and lentic environments throughout temperate regions.In considering the wide variety of riverine environments available to fish populations, one must examine the basic factors causing variation. Geomorphological _ features including stream order, basin area, basin relief ratio (elevation of source divided by length of river), position of groundwater input and the level of the water table interact with the amount and variability of rainfall to create variations in the velocity of riverine waters (Hynes, 1970; Lanka et al., 1987). These occur on both a general (i.e. longitudinally from headwater to estuary) and localised basis and affect a range of stream features, such as channel morphology, temperature regime, turbidity, and sedimentation. The flow rate is thus largely determined by topographic and climatic conditions external to the river and can be considered as the major feature through which variation in the stream habitat is mediated.
On the relationship between stock prices and consumer confidence
Creators: name: Stahan, Venere Gauvreau
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this investigation was to explore the relationship between the general psychological mood of the population regarding the national economy and its effect upon the level of stock market prices. It was hypothesized that there should be evidence of a positive relation between the two. In an effort to explain stock price levels several models were constructed which contained various component variables, among which were an Index of Consumer Mood, GNP, Corporate Earnings Before Tax, Money Supply and Canadian Government Long-Term Bond Interest Rates. All datum covered 38 quarters, from 3rd quarter I960 to 4th quarter 1969. From these variables five models were constructed containing three equations each. Five tests were conducted on the five individual models in which the correlations, multiple regressions and polynomial distributed lags were measured. Various tests contained data based on first differences deflated values, relative differences and combinations thereof. A final test was with the exclusion of the Consumer Mood variable in order to judge the effect its presence had made upon the accuracy of the equations. The conclusions based upon the results of the tests must initially indicate that the general psychological consumer attitude has little bearing upon the level of stock prices. Deflated money supply however, proved to be highly relevant and a valuable predictor. The total picture presented by the models is unsatisfactory, requiring either the substitution of more accurate variables or the inclusion of further data to supplant the inefficiency of the variables that were used. The components employed in the tests were both inefficient in some cases and insufficient in others. The results must only indicate areas for further investigation and refinement of the datum. Any generalization on the lack of statistical support for a relationship between consumer confidence and stock prices to the effect of consumer opinions about the economy as a whole would neither be reasonable nor justifiable at this time.

Various known local results are generalized and other new intrinsic results are obtained. Nontrivial characterizations of projective changes are given. The fundamental projectively invariant tensors, namely, the projective deviation tensor, the Weyl torsion tensor, the Weyl curvature tensor and the Douglas tensor are investigated. The properties of these tensors and their interrelationships are obtained. Projective connections and projectively flat manifolds are characterized. The present work is entirely intrinsic (free from local coordinates).

Simultaneously Sparse Solutions to Linear Inverse Problems with Multiple System Matrices and a Single Observation Vector

Year: 2009

description: A linear inverse problem is proposed that requires the determination of multiple unknown signal vectors. Each unknown vector passes through a different system matrix and the results are added to yield a single observation vector. Given the matrices and lone observation, the objective is to find a simultaneously sparse set of unknown vectors that solves the system. We will refer to this as the multiple-system single-output (MSSO) simultaneous sparsity problem. This manuscript contrasts the MSSO problem with other simultaneous sparsity problems and conducts a thorough initial exploration of algorithms with which to solve it. Seven algorithms are formulated that approximately solve this NP-Hard problem. Three greedy techniques are developed (matching pursuit, orthogonal matching pursuit, and least squares matching pursuit) along with four methods based on a convex relaxation (iteratively reweighted least squares, two forms of iterative shrinkage, and formulation as a second-order cone program). The algorithms are evaluated across three experiments: the first and second involve sparsity profile recovery in noiseless and noisy scenarios, respectively, while the third deals with magnetic resonance imaging radio-frequency excitation pulse design.

Expanding atmosphere models for SSS spectra of novae

Year: 2010
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Super Soft Source (SSS) spectra are powered by nuclear burning on the surface of a white dwarf. The released energy causes a radiatively-driven wind that leads to a radially extended atmosphere around the white dwarf. Significant blue shifts in photospheric absorption lines are found in the spectra of novae during their SSS phase, being an evidence of continued mass loss in this phase. We present spherically symmetric PHOENIX models that account for the expansion of the ejecta. A comparison to a plane parallel, hydrostatic atmosphere model demonstrates that the mass loss can have a significant impact on the model spectra. The dynamic model yields less pronounced absorption edges, and harder X-ray spectra are the result. Therefore, lower effective temperatures are needed to explain the observed spectra. Although both types of models are yet to be fine-tuned in order to accurately determine best fit parameters, the implications on the chemical abundances are going in opposite directions. With the expanding models the requirement for strong depletion of the crucial elements that cause these edges is now avoidable.

Quantum transport in honeycomb lattice ribbons with armchair and zigzag edges coupled to semi-infinite linear chain leads

description: We study quantum transport in honeycomb lattice ribbons with either armchair or zigzag edges. The ribbons are coupled to semi-infinite linear chains serving as the input and output leads and we use a tight-binding Hamiltonian with nearest-neighbor hops. For narrow ribbons we find transmission gaps for both types of edges. The center of the gap is at the middle of the band in ribbons with armchair edges. This symmetry is due to a property satisfied by the matrices in the resulting linear problem. In ribbons with zigzag edges the gap center is displaced to the right of the middle of the band. We also find transmission oscillations and resonances within the transmitting region of the band for both types of edges. Extending the length of a ribbon does not affect the width of the transmission gap, as long as the ribbon's length is longer than a critical value when the gap can form. Increasing the width of the ribbon, however, changes the width of the gap. In armchair edges the gap is not well-defined because of the appearance of transmission resonances while in zigzag edges the gap width systematically shrinks as the width of the ribbon is increased. We also find only evanescent waves within the gap and both evanescent and propagating waves in the transmitting regions.

description: Antibiotikaresistens är ett globalt hot mot vår hälsa och samhällsutvecklingen. Vårt beteende och våra val kan påverka utvecklingen i både positiv och negativ riktning. Den ökande antibiotikaresistensen är därför ett problem som vi alla måste ta ansvar för tillsammans. Ansvaret sträcker sig från förskrivning av antibiotika inom hälso- och sjukvården hela vägen till de produkter vi väljer i livsmedelsbutikernas mejeriavdelningar och om vi ser till att vara ordentligt vaccinerade innan vi reser bort. Om vi lyckas bibehålla effektiva antibiotika eller inte beror på hur vi beter oss. Därför behöver allmänheten kunskap om hur våra individuella val påverkar utvecklingen av antibiotikaresistens. Vi behöver också bli medvetna om varför vi ibland använder antibiotika ansvarsfullt och varför vi ibland agerar mindre ansvarsfullt. Samt förstå vad som får oss att ändra vårt beteende i rätt riktning. I detta policy brief finns Mirko Ancillottis rekommendationer för hur man skapar förutsättningar för individer att bidra till minskad antibiotikaresistens.

The impact of the colonial legacy on development in the third world states : the case of Ghana
Creators: name: Bannerman-Wood, Samuel
Publisher: name: University Of Tasmania
Year: 2023

description: Ghana, like most of the third world countries, is in transition from a traditional society with a colonial heritage to an independent developed society; a society where all available resources could be harnessed to achieve the objectives and goals of national development. Twenty-seven years after independence however, this objective has not been realized. The task of achieving the goals of national development has been painfully slow. There is still a high degree of underdevelopment, poverty, disease and deprivation. The economy has deteriorated over the years. Traditionally, many reasons have been given for this state of affairs. Among them are; bad economic planning, world recession, rising oil bills and lack of ideological direction. In finding solutions to these problems economists have played a leading role with various economic models and theories of development. The problem however remains unresolved. These explanations do not offer adequate analysis of the basis of our underdevelopment. The problem relates to the institutional structures of colonialism.

description: We present wide-field imaging and polarimetry at 20GHz of seven of the most extended, bright (Stot >= 0.50 Jy), high-frequency selected radio sources in the southern sky with declinations < -30 deg. Accompanying the data are brief reviews of the literature for each source, The results presented here aid in the statistical completeness of the Australia Telescope 20GHz Survey's bright source sample. The data are of crucial interest for future cosmic microwave background missions as a collection of information about candidate calibrator sources. We are able to obtain data for seven of the nine sources identified by our selection criteria. We report that Pictor A is thus far the best extragalactic calibrator candidate for the Low Frequency Instrument of the Planck European Space Agency mission due to its high level of integrated polarized flux density (0.50+/-0.06 Jy) on a scale of 10 arcmin. Six of the seven sources have a clearly detected compact radio core, with either a null or less than two percent detection of polarized emission from the nucleus. Most sources with detected jets have magnetic field alignments running in a longitudinal configuration, however PKS1333-33 exhibits transverse fields and an orthogonal change in field geometry from nucleus to jets.

Evidence for departure from a power-law flare size distribution for a small solar active region

description: Active region 11029 was a small, highly flare-productive solar active region observed at a time of extremely low solar activity. The region produced only small flares: the largest of the $>70$ Geostationary Observational Environmental Satellite (GOES) events for the region has a peak 1--$8Å$ flux of $2.2\times 10^{-6} {\rm W} {\rm m}^{-2}$ (GOES C2.2). The background-subtracted GOES peak-flux distribution suggests departure from power-law behavior above $10^{-6} {\rm W} {\rm m}^{-2}$, and a Bayesian model comparison strongly favors a power-law plus rollover model for the distribution over a simple power-law model. The departure from the power law is attributed to this small active region having a finite amount of energy. The rate of flaring in the region varies with time, becoming very high for two days coinciding with the onset of an increase in complexity of the photospheric magnetic field. The observed waiting-time distribution for events is consistent with a piecewise-constant Poisson model. These results present challenges for models of flare statistics and of energy balance in solar active regions.

The alternative shorter sea routes via Isthmus of Kra : the land bridge approach
Creators: name: Chulikpongse, Sommart
Publisher: name: University Of Tasmania
Year: 2023

description: The Kra Canal was originally proposed due to the geographic indication that a shorter Sea route might be achieved between the Far East and the Bay of Bengal area and the Persian Gulf. Of course, in Thailand the Kra project has recently (1981-1983) been discussed a great deal and commands wide interest among policy-makers and the informed public. The Kra project involves not only the construction of a new waterway capable of greatly easing ocean-going traffic between the Pacific and the Indian Oceans basins but also the projected industrial development zones and transshipment facilities associated with the canal project are of major significance for the entire Thai and broader regional economies. So far there is no evidence that the Kra Canal will become reality. This research is a preliminary attempt to analyse the Kra project but base on the concept that the land bridge would be introduced in conjunction with two container ports, one on the Eastern coast along the Gulf of Thailard, and the other on the Western coast along the Andaman Sea. If a railway network will link the two ports, thus intermodalism should provide the alternative possible service to the shippers. In the first part, the infrastructures between the two proposed ports - Port of Songkhla and Port of Satun, the strategy for port development, the justification for the route are surveyed. Then, an analysis of the two ports investment project and the Songkhla-Satun Kra Land Bridge project are carried out by using benefit-cost study and present value methods. The results Obtained show that port projects and the land, bridge project are apparently viable when using discout rates under 9% and 8% respectively. Finally, the study concentrated on the economic impact of the Kra Land Bridge and the establishment of regional marketing depots; and major specific rationales are all found to have a significant effect on port development and the land bridge.

description: Two-photon annihilation rates of $2^+$ tensor charmonium and bottomonium up to third radial excited states are estimated in the relativistic Salpeter method. Full Salpeter equation for $2^+$ tensor state is solved with a well defined relativistic wave function and we calculated the annihilation amplitude using the Mandelstam formalism. Our estimates of the decay widths are: $Γ(χ_{c2} \to 2γ)=501$ eV, $Γ(χ'_{c2} \to 2γ)=534$ eV, $Γ(χ_{b2} \to 2γ)=7.4$ eV and $Γ(χ'_{b2} \to 2γ)=7.7$ eV. We also give total decay widths of the lowest states estimated by the two-gluon decay rates, and the results are: $Γ_{tot}(χ_{c2})=2.64$ MeV, $Γ_{tot}(χ_{b2})=0.220$ MeV and $Γ_{tot}(χ'_{b2})=0.248$ MeV.

description: To address the global problem of single-use plastic waste, tailored behavior change interventions need to be developed which respond to the way different audiences think and act. The current study adopted a behavior-based segmentation approach, underpinned by the theory of normative social behavior and empirical testing, to better understand plastic consumption and the effect of existing media communications. Using a sample of 1001 respondents, Two-Step Cluster Analysis identified two key consumer types: “Plastic Avoiders” and “Plastic Users.” The two groups differed significantly on demographic characteristics, media use/exposure, and theoretical constructs. The most important predictors of group membership were self-efficacy and work status. An experiment involving pre-existing environmental media communications revealed that perceptions, intentions, and behaviors were influenced differently across the two audiences. The findings suggest that mobilizing existing media content may provide a cost-effective way for environmental communicators to increase their public impact while avoiding unintended consequences.

description: The present thesis examined the coping strategies employed by adolescents in high-risk drinking situations. Adolescent drinking practices are affected by influences from four main sources. They are as follows: Culture, Family, Peer and Self. The present paper examined the different responses of adolescents when faced with influences from these sources. Eighty male adolescents (aged 13-17 years) were drawn from two populations, Christian based youth groups and State League Football Clubs. They were asked to describe the two most recent high-risk drinking situations they had experienced, that is, a situation in which they did not want to drink alcohol but were most tempted to do so. The subjects were asked to recall their cognitions and behaviours throughout each situation. From the situation descriptions, the physical and social characteristics were examined. Utilisation of different coping strategies were then compared across different social and physical settings. Seventeen coping strategies were identified that were extensively used by male adolescents. An examination of the utilisation profiles for each strategy demonstrated that the employment of different strategies was affected by the social setting, the proportion of friends drinking, and offers of alcohol. Strategies employed in situations involving high levels of stress were aimed at removing the pressures acting upon them (problem-focused coping).
Spin-dependent pump current and noise in an adiabatic quantum pump based on domain walls in a magnetic nanowire

description: We study the pump current and noise properties in an adiabatically modulated magnetic nanowire with double domain walls (DW). The modulation is brought about by applying a slowly oscillating magnetic and electric fields with a controllable phase difference. The pumping mechanism resembles the case of the quantum dot pump with two-oscillating gates. The pump current, shot noise, and heat flow show peaks when the Fermi energy matches with the spin-split resonant levels localized between the DWs. The peak height of the pump current is an indicator for the lifetime of the spin-split quasistationary states between the DWs. For sharp DWs, the energy absorption from the oscillating fields results in side-band formations observable in the pump current. The pump noise carries information on the correlation properties between the nonequilibrium electrons and the quasi-holes created by the oscillating scatterer. The ratio between the pump shot noise and the heat flow serves as an indicator for quasi-particle correlation.

description: Guided by the theory of planned behavior (TPB), this study examines how self-construal, risk perception, and direct experience change the relative importance of psychosocial motivators in predicting intentions to engage in three different protective behaviors against particulate air pollution. An online survey of 1245 South Koreans (Mage = 42.22, 50% male) showed that self-efficacy was the strongest predictor of self-protective intentions. For those who construed the self as independent and perceived a higher risk, self-efficacy was a more important determinant for protective intentions. Self-efficacy exerted less influence on the formation of behavioral intentions, for those whom risk impacted personally. This study contributes to the theoretical extension of the TPB, by addressing specific conditions under which the TPB improves its predictive power. This study also provides practical insights into communicating environmental risk and promoting self-protective behaviors against the risk.

Compression of ultrashort UV pulses in a self-defocusing gas

description: Compression of UV femtosecond laser pulses focused into a gas cell filled with xenon is reported numerically. With a large negative Kerr index and normal dispersion, xenon promotes temporal modulational instability (MI) which can be monitored to shorten ~ 100 fs pulses to robust, singly-peaked waveforms exhibiting a fourfold compression factor. Combining standard MI theory with a variational approach allows us to predict the beam parameters suitable for efficient compression. At powers < 30 MW, nonlinear dispersion is shown to shift the pulse temporal profile to the rear zone.

\The Masters are close to an isolated lodge\" : the Theosophical Society in Tasmania 1889-1930"

description: The interaction of severe social change, new creeds and challenged beliefs during the nineteenth century created a cultural crisis for western society which would enable the Theosophical Society to emerge as an answer to that crisis. The publication of 'The Origin of Species' in 1859 is a suitable starting point. The cultural impact of Darwin's work was wide-reaching, and those who read Darwin were only a fraction of those exposed to Darwinian ideas. Evolutionary notions settled on the bed of popular perceptions and, losing none of their potency, produced a great variety of expressions, even contradictory ones and the full impact of evolutionary theory upon the late nineteenth century mind caused the disquiet that pervaded late Victorian thinking. A changing view of the Bible accompanied the adjustment to modern science and the appearance of 'Essays and Reviews' by seven liberal churchmen in 1860 presented a further shock. The higher criticism of the Tubingen School (denying Mosaic authorship of the Penteteuch and questioning the historical accuracy of the Old Testament, its rejection of the miracles and the old notion of prophecy) transmitted to English readers challenges to the Bible as an inspired and infallible book.

description: The primary reflection is that the MFA Course is a golden opportunity to proceed in a different direction to that which I had been following. It is realistic however that many of the inherent concerns of the past few years will continue to assert themselves and the aim now is to accommodate these in a more challenging format. In the initial proposal I stated that I wanted to pursue a path that set aside values such as classical beauty. I now feel that it would be more valid to explore what beauty is in a wider context, before attempting to reject it. Therefore I wish to extend my interest beyond the classical simplicity of the wheel thrown vessel to sculptural forms that are in their influences more reflective of the coming of the machine age and our contemporary milieu. I now find the original proposal to be restrictive in its emphasis on the primitive as a source of vitality and freedom of expression. Furthermore, the selection of\ the humorous the fantastic the whimsical and the magical\" is narrow and the expression available within does not contain the elements of darker forces that I also want to allude to in my course-work. The machine is often portrayed as the servant one who contains the potential to be the master. The work I envisage will reflect human relationships with the machine in many of its permutations. Within this I also include the political machine and the use of images of the mechanical machine as a metaphor for the machinations of the political. Also within this structure I am interested in the placement of allusions to thought that process by which we determine the whole of our individual and collective consciousness and which often holds us overly in its embrace. As a sub plot I want at some stage to explore the relationship between 3D form and 2D representation in effectively communicating my ideas. By this I mean that my intention is to paint 2D works that will draw upon the images and icons of the sculptural forms I intend to make and to within this process to perhaps develop a synthesis or at least explore the possibility of some sort of mutually supportive relationship."
