description: Massive vector particles are minimal dark matter candidates that motivate a wide range of laboratory searches, primarily exploiting a postulated kinetic mixing with the photon. However, depending on the high energy field content, the dominant vector dark matter (VDM) coupling to visible particles may arise at higher operator dimension, motivating efforts to predict direct detection rates for more general interactions. Here we present the first calculation of VDM absorption through its coupling to electron electric (EDM) or magnetic (MDM) dipole moments, which can be realized in minimal extensions to the Standard Model and yield the observed abundance through a variety of mechanisms across the eV\,-\,MeV mass range. We compute the absorption rate of the MDM and EDM models for a general target, and then derive direct detection constraints from targets currently in use: Si and Ge crystals and Xe and Ar atoms. We find that current experiments are already sensitive to VDM parameter space corresponding to a cosmological freeze-in scenario, and future experiments will be able to completely exclude MDM and EDM freeze-in models with reheat temperatures below the electroweak scale. Additionally, we find that while constraints on the MDM interaction can be related to constraints on axion-like particles, the same is not true for the EDM model, so the latter absorption rate must be computed from first principles. To achieve this, we update the publicly available program EXCEED-DM to perform these new calculations.

description: We present the evolution of a supersonic wind interacting with a Boson Star (BS) and compare the resulting wind density profile with that of the shock cone formed when the wind is accreted by a non-rotating Black Hole (BH) of the same mass. The physical differences between these accretors are that a BS, unlike a BH has no horizon, it does not have a mechanical surface either and thus the wind is expected to trespass the BS. Despite these conditions, on the BS space-time the gas achieves a stationary flux with the gas accumulating in a high density elongated structure comparable to the shock cone formed behind a BH. The highest density resides in the center of the BS whereas in the case of the BH it is found on the downstream part of the BH near the event horizon. The maximum density of the gas is smaller in the BS than in the BH case. Our results indicate that the highest density of the wind is more similar on the BS to that on the BH when the BS has high self-interaction, when it is more compact and when the wind velocity is higher. We expect this and similar analyses help to know whether BSs can still be Black Hole mimickers or can be ruled out.

description: Technological know-how is necessary to make effectively use of new machinery and capital goods. Firms and employees accumulate technology-specific knowledge when working with specific machinery. Radical innovation differs by technology type and pre-existing knowledge may be imperfectly transferable across types. In this paper, I address the implications of cross-technology transferability of skills for firm-level technology adoption and its consequences for the direction of macroeconomic technological change. I propose a microeconomically founded model of technological learning that is based on empirical and theoretical insights of the innovation literature. In a simulation study using the macroeconomic ABM Eurace@unibi-eco and applied to the context of green technology diffusion, it is shown that a high transferability of knowledge has ambiguous effects. It accelerates the diffusion process initially, but comes of the cost of technological stability and specialization in the long run. For firms, it is easy to adopt, but also easy to switch back to the conventional technology type. It is shown how different types of policies can be used to stabilize a technological transition pathway. The findings are summarized in a general taxonomic framework to characterize technologies. It represents a bottom-up approach to the study of technology transitions.

description: An ecosystem-based management approach (EBM) is suggested as one solution to help to tackle environmental challenges facing worldwide farming systems whilst ensuring socio-economic demands are met. Despite its usefulness, the application of this approach at the farm-scale presents several implementation problems, including the difficulty of (a) incorporating the concept of ecosystem services (ES) into agricultural land use decision-making and (b) involving the farmer in the planning process. This study aims to propose a solution to overcome these challenges by utilising a geodesign framework and EBM approach to plan and design a sustainable multifunctional agricultural landscape at the farm scale. We demonstrate how the proposed approach can be applied to plan and design multifunctional agricultural landscapes that offer improved sustainability, using a New Zealand hill country farm as a case study. A geodesign framework is employed to generate future land use and management scenarios for the study area, visualize changes, and assess the impacts of future land use on landscape multifunctionality and the provision of associated ES and economic outcomes. In this framework, collaboration with the farmer was carried out to obtain farm information and co-design the farmed landscapes. The results from our study demonstrate that farmed landscapes where multiple land use/ land cover types co-exist can provide a wide range of ES and therefore, meet both economic and environmental demands. The assessment of impacts for different land use change scenarios demonstrates that land use change towards increasing landscape diversity and complexity is a key to achieving more sustainable multifunctional farmed landscapes. The integration of EBM and geodesign, is a transdisciplinary approach that can help farmers target land use and management decisions by considering the major ES that are, and could be, provided by the landscapes in which these farm systems are situated, therefore maximising the potential for beneficial outcomes.

description: We model the infall of a 2e5 Msun satellite galaxy on to the inner 200 parsec of our Galaxy, to test whether the satellite could perturb the gas previously on stable orbits in the central molecular zone (CMZ), as proposed by Lang et al. (2013). This process would have driven a large gas inflow around 10 Myr ago, necessary to explain the past high accretion rate onto the super-massive black hole, and the presence of young stars in the inner parsecs of the Galaxy. Our hydrodynamical simulations show a much smaller inflow of gas, not sufficient to produce the aforementioned effects.

description: The energy-water demands of metropolitan regions and agricultural ecosystems are ever-increasing. To tackle this challenge efficiently and sustainably, the interdependence of these interconnected resources has to be considered. In this work, we present a holistic decision-making framework which takes into account simultaneously a water and energy supply system with the capability of satisfying metropolitan and agricultural resource demands. The framework features: (i) a generic large-scale planning and scheduling optimization model to minimize the annualized cost of the design and operation of the energy-water supply system, (ii) a mixed-integer linear optimization formulation, which relies on the development of surrogate models based on feedforward artificial neural networks and first-order Taylor expansions, and (iii) constraints for land and water utilization enabling multi-objective optimization. The framework provides the operational profiles of all energy-water system elements over a given time horizon, which uncover potential synergies between the essential food, energy, and water resource supply systems.

description: The recent discovery of topological Kondo insulating behaviour in strongly correlated electron systems has generated considerable interest in Kondo insulators both experimentally and theoretically. The Kondo semiconductors CeT2Al10 (T=Fe, Ru and Os) possessing a c-f hybridization gap have received considerable attention recently because of the unexpected high magnetic ordering temperature of CeRu2Al10 (TN=27 K) and CeOs2Al10 (TN=28.5 K) and the Kondo insulating behaviour observed in the valence fluctuating compound CeFe2Al10 with a paramagnetic ground state down to 50 mK. We are investigating this family of compounds, both in polycrystalline and single crystal form, using inelastic neutron scattering to understand the role of anisotropic c-f hybridization on the spin gap formation as well as on their magnetic properties. We have observed a clear sign of a spin gap in all three compounds from our polycrystalline study as well as the existence of a spin gap above the magnetic ordering temperature in T=Ru and Os. Our inelastic neutron scattering studies on single crystals of CeRu2Al10 and CeOs2Al10 revealed dispersive gapped spin wave excitations below TN. Analysis of the spin wave spectrum reveals the presence of strong anisotropic exchange, along the c-axis (or z-axis) stronger than in the ab-plane. These anisotropic exchange interactions force the magnetic moment to align along the c-axis, competing with the single ion crystal field anisotropy, which prefers moments along the a-axis. In the paramagnetic state (below 50 K) of the Kondo insulator CeFe2Al10, we have also observed dispersive gapped magnetic excitations which transform into quasi-elastic scattering on heating to 100 K. We will discuss the origin of the anisotropic hybridization gap in CeFe2Al10 based on theoretical models of heavy-fermion semiconductors.

description: Two possible physical mechanisms of superconductivity suppression at superconductor/antiferromagnet (S/AF) interfaces, which work even for interfaces with compensated antiferromagnets, were reported. One of them suggests that the Neel order of the AF induces rapidly oscillating spin-triplet correlations in the S layer. They are called Neel triplets, and they suppress singlet superconductivity. Nonmagnetic disorder destroys this type of triplet correlations. As a result, the critical temperature of the S/AF bilayer grows with impurity strength. The second mechanism, on the contrary, suggests that nonmagnetic impurity scattering suppresses superconductivity in S/AF hybrids. The predictions were made in the framework of two different quasiclassical approaches [G. A. Bobkov et al. Phys. Rev. B 106, 144512 (2022) and E. H. Fyhn et al. arXiv:2210.09325]. Here we suggest the unified theory of the proximity effect in thin-film S/AF structures, which incorporates both pictures as limiting cases, and we study the proximity effect at S/AF interfaces for arbitrary impurity strength, chemical potential, and the value of the Neel exchange field.

description: The investigation of 2D van der Waals (vdW) materials is a vibrant, fast moving and still growing interdisciplinary area of research. 2D vdW materials are truly 2D crystals with strong covalent in-plane bonds and weak van der Waals interaction between the layers with a variety of different electronic, optical and mechanical properties. A very prominent class of 2D materials are transition metal dichalcogenides (TMDs) and amongst them particularly the semiconducting subclass. Their properties include bandgaps in the near-infrared to the visible range, decent charge carrier mobility together with high (photo-)catalytic and mechanical stability and exotic many body phenomena. These characteristics make the materials highly attractive for both fundamental research as well as innovative device applications. Furthermore, the materials exhibit a strong light matter interaction providing a high sun light absorbance of up to 15% in the monolayer limit, strong scattering cross section in Raman experiments and access to excitonic phenomena in vdW heterostructures. This review focuses on the light matter interaction in MoS2, WS2, MoSe2, and WSe2 that is dictated by the materials complex dielectric functions and on the multiplicity of studying the first order phonon modes by Raman spectroscopy to gain access to several material properties such as doping, strain, defects and temperature. 2D materials provide an interesting platform to stack them into vdW heterostructures without the limitation of lattice mismatch resulting in novel devices for application but also to study exotic many body interaction phenomena such as interlayer excitons. Future perspectives of semiconducting TMDs and their heterostructures for applications in optoelectronic devices will be examined and routes to study emergent fundamental problems and many-body quantum phenomena under excitations with photons will be discussed.

description: We present a method of calculating the energy gap of a charge-neutral excitation using only ground-state calculations. We report Quantum Monte Carlo calculations of $Γ\rightarrowΓ$ and $Γ\rightarrow X$ particle-hole excitation energies in diamond carbon. We analyze the finite-size effect and find the same $1/L$ decay rate as that in a charged excitation, where $L$ is the linear extension of the supercell. This slow decay is attributed to the delocalized nature of the excitation in supercells too small to accommodate excitonic binding effects. At larger system sizes, the apparent $1/L$ decay crosses over to a $1/L^3$ behavior. Estimation of the scale of exciton binding can be used to correct finite-size effects of neutral gaps.

description: Large pre-trained neural networks are ubiquitous and critical to the success of many downstream tasks in natural language processing and computer vision. However, within the field of web information retrieval, there is a stark contrast in the lack of similarly flexible and powerful pre-trained models that can properly parse webpages. Consequently, we believe that common machine learning tasks like content extraction and information mining from webpages have low-hanging gains that yet remain untapped. We aim to close the gap by introducing an agnostic deep graph neural network feature extractor that can ingest webpage structures, pre-train self-supervised on massive unlabeled data, and fine-tune to arbitrary tasks on webpages effectually. Finally, we show that our pre-trained model achieves state-of-the-art results using multiple datasets on two very different benchmarks: webpage boilerplate removal and genre classification, thus lending support to its potential application in diverse downstream tasks.

The rhetoric of reconciliation: evidence and judicial subjectivity in Cubillo v Commonwealth
Creators: name: Luker, Trish
Publisher: name: La Trobe
Year: 2023

description: In August 2000, Justice O'Loughlin of the Federal Court of Australia handed down the decision in Cubillo v Commonweath in which Lorna Cubillo and Peter Gunner took action against the Commonwealth Government, arguing that it was vicariously liable for their removal from their families and communities as children and subsequent detentions in the Northern Territory during the 1940s and 1950s. The case is the landmark decision in relation to legal action taken by members of the Stolen Generations. Using the decision in Cubillo as a key site of contestation, my thesis provides a critique of legal positivism as the dominant jurisprudential discourse operating within the Anglo- Australian legal system. I argue that the function of legal positivism as the principal paradigm and source of authority for the decision serves to ensure that the debate concerning reconciliation in Australia operates rhetorically to maintain whiteness at the centre of political and discursive power. Specifically concerned with the performative function of legal discourse, the thesis is an interrogation of the interface of law and language, of rhetoric, and the semiotics of legal discourse. The dominant theory of evidence law is a rationalist and empiricist epistemology in which oral testimony and documentary evidence are regarded as mediating the relationship between proof and truth. I argue that by attributing primacy to principles of rationality, objectivity and narrative coherence, and by privileging that which is visually represented, the decision serves an ideological purpose which diminishes the significance of race in the construction of knowledge. Legal positivism identifies the knowing subject and the object of knowledge as discrete entities. However, I argue that in Cubillo, Justice O'Loughlin inscribes himself into the text of the judgment and in doing so, reveals the way in which textual and corporeal specificities undermine the pretence of objective judgment and therefore the source of judicial authority.

The influence of values on development practice: a study of Cambodian development practitioners in non-government organisations in Cambodia
Creators: name: O'Leary, Moira
Publisher: name: La Trobe
Year: 2023

description: Evaluation reports, along with development studies literature suggest that development practice is often failing to enact espoused participatory, empowering and gender equitable approaches or to achieve these espoused goals. Mainstream development theories are underpinned by values and beliefs about what is good and what "ought to be". In this study I explore the influence of values on the development practice of Cambodian practitioners working in non-government organisations in rural Cambodia. Development practitioners are the major conduit of community based development assistance, but little is known about how their values impact their day-to-day practice, and influence their moral and political choices. In the study I used ethnographic methodology, guided by feminist principles. The research was conducted with individuals and groups of experienced, mostly Cambodian development practitioners. Data were collected in four phases through in-depth and semi-structured interviews, focus group discussions and observations of practice. I examine the (in)congruity between practitioners' espoused theories and values and those demonstrated by their practice. The findings reveal that the values are not essentially different but are prioritized differently. The espoused values are consistent with those of the international development discourse, all of which are premised on a belief in human equality. Theories and values inferred from actual practice reflect hierarchical underpinnings. In the Cambodian context this is consistent with socio-cultural values and the hierarchical order of society. However, as expatriate research participants and the literature attest, this incongruence is not particular to Cambodian practitioners. The study reveals practitioners give higher priority to fulfilling the tasks necessary for the achievement of their NGOs' planned outputs and organisational imperatives than to the facilitation of participatory and empowering processes. At the same time, the enactment of some development values is in tension with certain socio-cultural norms and practices. Practitioners are challenged to make desirable development values explicit and identify how to operationalise them in the lived social, cultural, political and economic context.

description: The Miniature X-ray Solar Spectrometer (MinXSS) are twin 3U CubeSats. The first of the twin CubeSats (MinXSS-1) launched in December 2015 to the International Space Station for deployment in mid-2016. Both MinXSS CubeSats utilize a commercial off the shelf (COTS) X-ray spectrometer from Amptek to measure the solar irradiance from 0.5 to 30 keV with a nominal 0.15 keV FWHM spectral resolution at 5.9 keV, and a LASP-developed X-ray broadband photometer with similar spectral sensitivity. MinXSS design and development has involved over 40 graduate students supervised by professors and professionals at the University of Colorado at Boulder. The majority of previous solar soft X-ray measurements have been either at high spectral resolution with a narrow bandpass or spectrally integrating (broadband) photometers. MinXSS will conduct unique soft X-ray measurements with moderate spectral resolution over a relatively large energy range to study solar active region evolution, solar flares, and the effects of solar soft X-ray emission on Earth's ionosphere. This paper focuses on the X-ray spectrometer instrument characterization techniques involving radioactive X-ray sources and the National Institute for Standards and Technology (NIST) Synchrotron Ultraviolet Radiation Facility (SURF). Spectrometer spectral response, spectral resolution, response linearity are discussed as well as future solar science objectives.

Population demographics of New Zealand fur seals (Arctocephalus forsteri)
Creators: name: McKenzie, Jane
Publisher: name: La Trobe
Year: 2023

description: Assessment of trophic interactions between increasing populations of New Zealand fur seals (Arctocephalus forsteri) and fisheries in southern Australia is limited due to a lack of species specific demographic data and an understanding of the factors influencing population growth. To establish species specific demographic parameters a cross-sectional sample of New Zealand fur seal females (330) and males (100) were caught and individually-marked on Kangaroo Island, South Australia between 2000 and 2003. The seals were aged through examination of a postcanine tooth, which was removed from each animal to investigate age-specific life-history parameters. Annual formation of cementum layers was confirmed and accuracy in age estimation was determined by examination of teeth removed from individuals of known-age.Indirect methods of assessing reproductive maturity based on mammary teat characteristics indicated that females first gave birth between 4-8 years of age, with an average age at reproductive maturity of 5 years. Among reproductively mature females, age-specific reproductive rates increased rapidly between 4-7 years of age, reaching maximum rates of 70-81% between 8-13 years, and gradually decreased in older females. No females older than 22 years were recorded to pup. Age of first territory tenure in males ranged from 8-10 years. The oldest female and male were 25 and 19 years old, respectively. Post-weaning growth in females was monophasic, characterised by high growth rates in length and mass during the juvenile growth stage, followed by a gradual decline in growth rates after reproductive maturity.In contrast, growth in males was biphasic and displayed a secondary growth spurt in both length and mass, which coincided with sexual and social maturation, followed by a rapid decline in growth rates. Age-specific survival rates were high (0.823-0.953) among prime-age females (8-13yrs of age) and declined in older females. Relative change in annual pup production was strongly correlated with reproductive rates of prime-age females and adult female survival between breeding seasons.

description: Dielectric metasurfaces require high refractive index contrast materials for optimum performance. This requirement imposes a severe restraint; devices have either been demonstrated at wavelengths of 700nm and above using high-index semiconductors such as silicon, or they use lower index dielectric materials such as TiO$_{2}$ or Si$_{3}$N$_{4}$ and operate in the visible wavelength regime. Here, we show that the high refractive index of silicon can be exploited at wavelengths as short as 532 nm by demonstrating a silicon metasurface with a transmission efficiency of 47% at this wavelength. The metasurface consists of a graded array of silicon posts arranged in a square lattice on a quartz substrate. We show full 2π phase control and we experimentally demonstrate polarization-independent beam deflection at 532nm wavelength. The crystalline silicon is placed on a quartz substrate by a bespoke layer transfer technique and we note that an efficiency >70% may be achieved for a further optimized structure in the same material. Our results open a new way for realizing efficient metasurfaces based on silicon in the visible wavelength regime.

Carbon and water dynamics of peat soils in the Australian Alps
Creators: name: Grover, Samantha Patricia Power
Publisher: name: La Trobe
Year: 2023

description: Abstract: This research investigated carbon dynamics, water dynamics and peat formation at Wellington Plain peatland in the Victorian Alps. The properties of bog peat and dried peat were measured, and the ensuing results are outlined below. The carbon chemistries of both bog peat and dried peat displayed changes with depth consistent with an increase in the extent of decomposition of the organic material. Representative changes in the alkyl:O-alkyl ratio down the profile were 0.14 to 0.96 for bog peat and 0.28 to 1.07 for dried peat. Laboratory incubations on the influence of chemistry, particle size, water content and sample preparation indicated that, in the absence of confounding factors, peat chemistry was the most important factor in determining the size of the mineralisable carbon pool. Water content was the most important factor in determining the rate of carbon mineralization. In the field, both bog peat and dried peat emitted an average of 2 g CO₂/m₂/d from the surface. Carbon mineralisation was related to both soil temperature and soil water content, and this relationship was used to model peat mineralisation under a range of possible future climate scenarios. Below the surface, however, I measured lower rates of decomposition in the dried peat than in the bog peat.The water-holding capacity of peat was measured in the laboratory, as was the rate of water movement through peat. Specific yield decreased down the profile in both bog peat (0.88 to 0.45 cm3/cm3) and dried peat (0.36 to 0.11 cm3/cm3). Hydraulic conductivity also decreased down the profile in both peats: 5.1 x 10-4 to 3.0x10-6 m/s in bog peat, and 1.0x10-4 to 7.0x10-6 m/s in dried peat. Relationships between the hydrologic properties of peat and its physical and chemical properties were identified. In the field, fluctuations in the watertable were monitored in concert with rainfall. These laboratory and field measurements enabled me to develop models of the hydrology of bog peat and dried peat. Radioisotope dating indicated that both bog peat and dried peat began forming around 3300 years ago. The bog peat appeared to have drained to form dried peat between 131 and 139 years ago. Since that time, erosion appeared to have contributed more to the loss of organic material from dried peat than carbon mineralisation had.

The Catalan Equation in Finitely Generated Domains

description: We consider the Catalan equation $x^p - y^q = 1$ in unknowns $x, y, p, q$, where $x, y$ are taken from an integral domain $A$ of characteristic $0$ that is finitely generated as a $\mathbb{Z}$-algebra and $p, q > 1$ are integers. We give explicit upper bounds for $p$ and $q$ in terms of the defining parameters of $A$. Our main theorem is a more precise version of a result of Brindza. Brindza also gave inexplicit bounds for $p$ and $q$ in the special case that $A$ is the ring of $S$-integers for some number field $K$. As part of the proof of our main theorem, we will give a less technical proof for this special case with explicit upper bounds for $p$ and $q$.

description: After playing a pivotal role in the birth of the Standard Model in the 70's, the study of charm physics has undergone a revival during the last decade, triggered by a wealth of precision measurements from the charm and $B$ factories, and from the CDF and especially the LHCb experiments. In this article, we sum up how the unique phenomenology of charmed hadrons can be used to test the Standard Model and we review the latest measurements performed in this field by the LHCb experiment. These include the historic first observations of $CP$ violation and of a nonzero mass difference between the charmed neutral-meson mass eigenstates, the most precise determination of their decay-width difference to date, and a search for time-dependent $CP$ violation reaching the unprecedented precision of $10^{-4}$. These results challenge our comprehension of nonperturbative strong interactions, and their interpretation calls for further studies on both the theoretical and experimental sides. The upcoming upgrades of the LHCb experiment will play a leading role in this quest.

description: CONTEXT Multifunctionality can refer to the capacity of a landscape to provide a wide range of ecosystem services (ES). Maintaining or restoring multifunctionality in agricultural landscapes is considered an efficient solution to achieve sustainable agricultural production because multiple ES provided by a landscape can support both environmental protection and socio-economic benefits. Quantifying the provision of ES provides fundamental information to measure landscape multifunctionality and inform sustainable land management strategies. Although a large number of studies have been carried out to measure landscape multifunctionality and associated ES, comprehensive spatially explicit assessments at the farm scale are limited. OBJECTIVE This research applies a wide range of spatial models, tools, and methods to spatially quantify the provision of multiple ES as well as the pattern of landscape multifunctionality in farmed landscapes. METHODS To quantify the provision of multiple ES provided by the landscape, the bio-physical models provided by InVEST (e.g., Nutrient Delivery Ratio and Sediment Delivery Ratio models) and land use land cover-based assessments using spatial analysis tools in ArcGIS were employed. The Analytic Hierarchy Process was applied to calculate the landscape multifunctionality index which is an integration of multiple ES supply. Hot spot analysis using Getis Ord Gi* statistics was utilised to examine the spatial distribution of multiple ecosystem services. A hill country farm in New Zealand is chosen as a case study because it is a good example of a diverse landscape that is facing significant environmental issues due to intensive agricultural production. RESULTS AND CONCLUSIONS Our study reveals that the provision of ES and the pattern of landscape multifunctionality is highly variable across the farm. Both positive and negative relationships among ES are found and the interactions between them are mainly reflected in three ES bundles: the agricultural land, the indigenous forest and wetlands, and the mixed land uses. Furthermore, our study demonstrates that the quality of landscape is significantly dependent on the landscape management goals and preferences of the farmer so involving them into the process of ES and landscape multifunctionality assessment at a farm scale is essential step to obtain more comprehensive results. SIGNIFICANCE Results from this study enable important questions to be answered regarding the spatial variation of ES provision and how land use and land management goals relate to the value and quality of landscape multifunctionality. This can provide valuable information to design future multifunctional landscapes and inform decision making in relation to sustainable land use management.

description: This paper addresses a question about music cognition: how do we derive polymetric structures. A preference rule system is presented which is implemented into a drum computer. The preference rule system allows inferring local polymetric structures, like two-over-three and three-over-two. By analyzing the micro-timing of West African percussion music a timing pattern consisting of six pulses was discovered. It integrates binary and ternary rhythmic feels. The presented drum computer integrates the discovered superimposed polymetric swing (timing and velocity) appropriate to the rhythmic sequence the user inputs. For binary sequences, the amount of binary swing is increased and for ternary sequences, the ternary swing is increased.

Landscape painting: connection, perception and attention
Creators: name: Parker, Margaret Ina
Publisher: name: La Trobe
Year: 2023

description: I investigate the lived experience, the actuality of responding to land as a painter. This thesis consists of intensive investigations in the field and further exploration in the studio, resulting in a body of paintings and drawings which form the exhibition. The exegesis explores theories and ideas surrounding the work. The psychological engagement between people, land and art is of major concern. The choice of place selected to paint and the subject matter of rocks is discussed. Painters who work outside or have painted at the same site are considered for comparison with my working methods or concerns. The selective view is intimate. The format of the image and the composition are discussed in terms of proximity and space. Consideration of the psychology of engagement with land and landscape painting, either as an observer or painter, is a major component of the research.This examination of human psychological development illuminates the origin of our sense of self and how we relate to the land on which we live. The premise of this enquiry is the idea that art and culture could reflect human psychological development. Do art objects contribute to cultural understanding of the relationship of person to environment? A phenomenological perspective is incorporated in this exploration of the interrelation of vision, perception and attention. Can the reality of experience be transferred into the art work? The deep attention to the landscape of Australian Aboriginal people serves as a cultural reference for these investigations. This study concludes that sentient consciousness involving responsibility for land is an open, effective way of perceiving and depicting landscape. Responsibility for land can be encouraged by the development of cultural ideas based around landscape and can be the result of feeling connected to land. Art can contribute to changes in attitudes to land.
