description: The arrest of Langmuir-wave collapse by quantum effects, first addressed by Haas and Shukla [Phys. Rev. E 79, 066402 (2009)] using a Rayleigh-Ritz trial-function method is revisited, using rigorous estimates and systematic asymptotic expansions. The absence of blow up for the so-called quantum Zakharov equations is proved in two and three dimensions, whatever the strength of the quantum effects. The time-periodic behavior of the solution for initial conditions slightly in excess of the singularity threshold for the classical problem is established for various settings in two space dimensions. The difficulty of developing a consistent perturbative approach in three dimensions is also discussed, and a semi-phenomenological model is suggested for this case.

description: Using data from the SCUBA Legacy Catalogue (850 um) and Spitzer Space Telescope (3.6 - 70 um), we explore dense cores in the Ophiuchus, Taurus, Perseus, Serpens, and Orion molecular clouds. We develop a new method to discriminate submillimeter cores found by SCUBA as starless or protostellar, using point source photometry from Spitzer wide field surveys. First, we identify infrared sources with red colors associated with embedded young stellar objects (YSOs). Second, we compare the positions of these YSO-candidates to our submillimeter cores. With these identifications, we construct new, self-consistent starless and protostellar core mass functions (CMFs) for the five clouds. We find best fit slopes to the high-mass end of the CMFs of -1.26 +/- 0.20, -1.22 +/- 0.06, -0.95 +/- 0.20, and -1.67 +/- 0.72 for Ophiuchus, Taurus, Perseus, and Orion, respectively. Broadly, these slopes are each consistent with the -1.35 power-law slope of the Salpeter IMF at higher masses, but suggest some differences. We examine a variety of trends between these CMF shapes and their parent cloud properties, potentially finding a correlation between the high-mass slope and core temperature. We also find a trend between core mass and effective size, but we are very limited by sensitivity. We make similar comparisons between core mass and size with visual extinction (for A_V >= 3) and find no obvious trends. We also predict the numbers and mass distributions of cores that future surveys with SCUBA-2 may detect in each of these clouds.

Approach to Universality in Axisymmetric Bubble Pinch-Off

description: The pinch-off of an axisymmetric air bubble surrounded by an inviscid fluid is compared in four physical realizations: (i) cavity collapse in the wake of an impacting disc, (ii) gas bubbles injected through a small orifice, (iii) bubble rupture in a straining flow, and (iv) a bubble with an initially necked shape. Our boundary-integral simulations suggest that all systems eventually follow the universal behavior characterized by slowly varying exponents predicted in [Eggers et al., PRL 98, 094502 (2007)]. However, the time scale for the onset of this final regime is found to vary by orders of magnitude depending on the system in question: while for the impacting disc it is well in the millisecond range, for the gas injection needle universal behavior sets in only a few microseconds before pinch-off. These findings reconcile the different views expressed in recent literature about the universal nature of bubble pinch-off.
The relation between stellar mass and weak lensing signal around galaxies: Implications for MOND

description: We study the amplitude of the weak gravitational lensing signal as a function of stellar mass around a sample of relatively isolated galaxies. This selection of lenses simplifies the interpretation of the observations, which consist of data from the Red- sequence Cluster Survey and the Sloan Digital Sky Survey. We find that the amplitude of the lensing signal as a function of stellar mass is well described by a power law with a best fit slope α= 0.74 \pm 0.08. This result is inconsistent with Modified Newtonian Dynamics, which predicts α= 0.5 (we find α> 0.5 with 99.7% confidence). As a related test, we determine the MOND mass-to-light ratio as a function of luminosity. Our results require dark matter for the most luminous galaxies (L >=10^11 L_sun). We rule out an extended halo of gas or active neutrinos as a way of reconciling our findings with MOND. Although we focus on a single alternative gravity model, we note that our results provide an important test for any alternative theory of gravity.

The Unified Hybrid Format (UHF): A Phase-Coherent Representation Bridging Continuum and Quantization
Creators: name: Fedotov, Anton
name: SynqraTech
Publisher: name: Zenodo
Year: 2025

description: We introduce the Unified Hybrid Format (UHF) — a novel data representation framework that integrates spectral continuity, quantized phase reconstruction, and local coherence into a single adaptive format. Unlike traditional codecs (e.g., JPEG, MP3) or learned embeddings (e.g., CLIP, Word2Vec), UHF dynamically shifts between smooth and discrete modes of representation based on the internal phase structure of the signal.

UHF is defined by a triadic model:

Rcont: a continuum projection via low-frequency spectral filtering,

Rdisc: a reconstruction from quantized phase with original magnitudes,

κ(x): a coherence map expressing the local structural order of phase.

The hybrid form is computed by κ\kappaκ-weighted blending of these projections, producing a format that responds not to external instructions but to the morphology of the input itself.

We present the mathematical foundation of UHF, reference implementations in 1D and 2D (signals and images), and quantitative comparisons to conventional formats. We also demonstrate potential applications in phase-aware compression, structure-preserving visualization, generative art, and as an interface to coherence-based AI models.

UHF provides not just compression — it provides a form-sensitive, reactive substrate for multimodal computation. This work establishes the core architecture for coherence-centric data processing and invites further development of UHF as a general-purpose carrier of structure across domains.

description: This deliverable D2.4 is embedded in ANIMA work package WP2 – “Critical Review and Assessment of Noise Impact and Related Management Practices.” It refers to subtask 2.2.2 and serves – in conjunction with deliverable D2.3 from subtask 2.2.1 – the critical review of noise impact (task 2.2). This deliverable has three main topics. While deliverable D2.3 deals with aircraft noise-related health impacts in general, here (1) annoyance as an outcome is at the centre stage. Moreover, this deliverable (2) pursues a holistic approach to the emergence, maintenance and, especially, mitigation of aircraft noise annoyance. That is, in addition to acoustic variables, in particular the range of non-acoustical contributors is also examined, as well as the combined effects and interactions of acoustical and non-acoustical variables. Finally, based on the findings, (3) implications and recommendations for noise management strategies are derived and presented. The centrepieces to achieving these objectives are several systematic literature reviews.

I only look forward to Mondays‚ÄövÑvp : facilitating creative writing groups : ageism, action and empowerment
Creators: name: Webb, JM
Publisher: name: University Of Tasmania
Year: 2023

description: This study examines the changes, which occur when introducing residents in aged care facilities (RACFs) to creative experiences, specifically poetry and short prose. This is explored qualitatively by working with groups of residents in two Tasmanian RACFs. The theoretical background, research and methodology of this project examine how participatory creative activities, which produce both individual and communal writing, is beneficial to the wellbeing of residents in aged care facilities in Tasmania. This study uses Action Research as a methodology. Its flexibility enabled the project to grow, broaden intellectual concepts and deepen my understanding of arising issues. As a relationship developed between residents, and between residents and myself, we changed with each newly shared experience. Action Research is responsive to change and the cyclical process assists in reflecting on what has occurred; this enables critical planning to improve the creative process. The cycle of 'plan, act, observe and reflect' encouraged me to work collaboratively with members of the two groups; demonstrating two or more minds are better than one. Our developing communal reflection led us to the next cyclical challenge. This study encompasses the role of creativity in Australian RACFs and there is critical examination of the broader setting of Government policy and planning, in relation to the wellbeing of residents in RACFs. The focus of the study enlarged to the international field for examples of creative expression in other countries that perceive the value of creative expression, and are using this as a method that aims to benefit the frail aged in institutions. It is widely held there is an important relationship between the physical brain and human expressions of creativity. My investigations and experience with my two creative writing groups concurred: factors that reduce creativity are lack of confidence, negative feedback and domination of existing dogma. Using data from the creative writing groups, and research beyond these experiences, factors were identified that affect outcomes from writing groups. Action Research underpinned the project beyond the confines of the room in an aged care facility, to the capacity for growth in the frail aged, where environmental, social and political circumstances permit.

description: Koopman-von Neumann in the 30's gave an operatorial formululation of Classical Mechanics. It was shown later on that this formulation could also be written in a path-integral form. We will label this functional approach as CPI (for classical path-integral) to distinguish it from the quantum mechanical one, which we will indicate with QPI. In the CPI two Grassmannian partners of time make their natural appearance and in this manner time becomes something like a three dimensional supermanifold. Next we introduce a metric in this supermanifold and show that a particular choice of the supermetric reproduces the CPI while a different one gives the QPI.

Among friends : middle-class Tasmanians who moved to New Zealand, 1855-1875
Creators: name: Paterson, J
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis examines the movement of middle-class Tasmanians to New Zealand during the mid-nineteenth century. This group of people consisted primarily of entrepreneurs who were already crossing the Tasman Sea during the 1850s, and young professional men who left Tasmania in the wake of the Otago gold rush of the early 1860s. Neither ex-convicts nor gold seekers (nor whalers, soldiers, et al) are included in this research group ‚Äö- precisely those people who are currently found at the forefront of any discussion about the wider Australian movement into New Zealand during this period. This thesis takes a qualitative approach; it is the motivations and actions of the individuals concerned that are explored and analysed. Wherever possible first-hand accounts are utilised and it is from these that the thesis is generated. To this end a group of New Zealand-related letters was sourced from the Weston Collection at the Queen Victoria Museum and Art Gallery, Launceston. The Tasmanians referred to in these letters formed the core sample group for this research. An extended 'family history' was prepared for these people which included their interconnections with one another and their experiences both in Tasmania and in New Zealand. The experiences of this group of Tasmanians were then used to test the late nineteenth century Australia-New Zealand migration hypotheses of Rollo Arnold. Arnold's framework for defining the movements of Australians to New Zealand (and vice versa) included the concepts 'among friends', 'invisibility' and the 'perennial interchange', as well as the belief that a high proportion of Australians travelling to New Zealand during the nineteenth century were attempting to escape from their past. The stories of these middle-class Tasmanians provide a new lens through which to question perceptions of nineteenth century Australian people movement to New Zealand. The 'family history' approach followed during this research, with its accent on studying individual behaviour, has allowed this thesis to extend the discussion of Tasmanian movement to include return migration and multiple migration ‚Äö- a new approach within the Australia-New Zealand lexicon. While Arnold's concepts remain valid, future discussion must also now include the hitherto unrecognised predominance of native-born colonials, at least among middle-class migrants, as well as the important role played by their unmarried sisters.

description: In the context of the space-based mission CoRoT, devoted to asteroseismology and search for planet transits, we analyse the accuracy of fundamental stellar parameters (mass, radius, luminosity) that can be obtained from asteroseismological data.} Our work is motivated by the large uncertainties on planetary radius determination of transiting planets which are mainly due to uncertainties on the stellar parameters. Our goal is to analyse uncertainties of fundamental stellar parameters for a given accuracy of oscillation frequency determination. We generate grids of equilibrium models of stars and compute their pulsation spectra based on a linear nonadiabatic stability analysis. Using differents methods of comparison of oscillation mode spectra, we derive uncertainties on fundamental stellar parameters and analyse the effect of varying the number of considered modes.} The limits obtained depend strongly on the adapted method to compare spectra. We find a degeneracy in the stellar parameter solutions, up to a few % in mass (from less than 1% to more than 7% depending on the method used and the number of considered modes), luminosity (from 2% to more than 10%) or radius (from less than 1% to 3%), for a given pulsation spectrum.

Enhancing mathematics teacher educators' technological pedagogical content knowledge through collaborative professional development : Ethiopia
Creators: name: Getenet, ST
Publisher: name: University Of Tasmania
Year: 2023

description: This study documented the design, development and refinement of a professional development program, which improved teacher educators' knowledge, to facilitate their effective use of technology in teaching mathematics. The study was conducted in two Ethiopian Colleges of Teacher Education. It involved 16 mathematics teacher educators, four Information Communication Technology coordinators, and 247 elementary pre-service mathematics teachers. The study was undertaken across three phases. The first phase comprised a contextual and problem analysis and development of a conceptual framework based on a literature review that provided the basis to design the first professional development program prototype. The second phase involved setting out design guidelines and optimising the professional development program prototype through two cycles of design, formative refinement and revision. The last phase of the study was an evaluation of the extent to which the professional development program that took place over 5 months had met its objectives. The study used a mixed methods approach, which involved the collection of both quantitative and qualitative data informed by an educational design research methodology. Data were collected using questionnaires, observation checklists, semi-structured interviews, focus group discussions and professional learning workshops. One of the findings of the study in the first phase showed that the teacher educators believed they had little knowledge of technology and its effective use in their teaching of mathematics, and that this was a major barrier resulting in limited technology use in their teaching. The first phase of the study informed the design of the professional development program in the second phase of the study. The designed professional development program was characterised by its focus on the pedagogical use of technology, provision of exemplar material, the use of available and webbased technologies, the formation of teams, support from Information Communication Technology (ICT) coordinators, and an emphasis on informality in the professional development arrangements. The results in the third phase of the study showed that the professional development program contributed to increased use of technology by the mathematics teacher educators and their pre-service teachers. The teacher educators' perceived knowledge of how to use and integrate technology teaching practices in their teaching of mathematics was improved and this was associated with positive changes in their effective technology integrated mathematics teaching as evidenced by the classroom observations.

description: We review the particle theory origin of inflation and curvaton mechanisms for generating large scale structures and the observed temperature anisotropy in the cosmic microwave background (CMB) radiation. Since inflaton or curvaton energy density creates all matter, it is important to understand the process of reheating and preheating into the relevant degrees of freedom required for the success of Big Bang Nucleosynthesis. We discuss two distinct classes of models, one where inflaton and curvaton belong to the hidden sector, which are coupled to the Standard Model gauge sector very weakly. There is another class of models of inflaton and curvaton, which are embedded within Minimal Supersymmetric Standard Model (MSSM) gauge group and beyond, and whose origins lie within gauge invariant combinations of supersymmetric quarks and leptons. Their masses and couplings are all well motivated from low energy physics, therefore such models provide us with a unique opportunity that they can be verified/falsified by the CMB data and also by the future collider and non-collider based experiments. We then briefly discuss stringy origin of inflation, alternative cosmological scenarios, and bouncing universes.

description: The physics of interacting nuclear spins arranged in a crystalline lattice is typically described using a thermodynamic framework: a variety of experimental studies in bulk solid-state systems have proven the concept of a spin temperature to be not only correct but also vital for the understanding of experimental observations. Using demagnetization experiments we demonstrate that the mesoscopic nuclear spin ensemble of a quantum dot (QD) can in general not be described by a spin temperature. We associate the observed deviations from a thermal spin state with the presence of strong quadrupolar interactions within the QD that cause significant anharmonicity in the spectrum of the nuclear spins. Strain-induced, inhomogeneous quadrupolar shifts also lead to a complete suppression of angular momentum exchange between the nuclear spin ensemble and its environment, resulting in nuclear spin relaxation times exceeding an hour. Remarkably, the position dependent axes of quadrupolar interactions render magnetic field sweeps inherently non-adiabatic, thereby causing an irreversible loss of nuclear spin polarization.

description: We present an update of the orbital ephemeris of the binary X-ray pulsar Her X-1 and determine an improved value for the rate of orbital decay. In addition, we report the first measurement of the orbital eccentricity. We have analyzed pulse timing data of Her X-1 from X-ray observations by RXTE (Rossi X-Ray Timing Explorer) and INTEGRAL over the period 1996-2007. Accurate pulse arrival times were determined from solar system bary-centered photon arrival times by generating pulse profiles averaged over appropriately short integration times. Applying pulse phase connection techniques, it was possible to determine sufficiently accurate local ephemeris data for seven observation periods distributed over 12 years. Combining the new local T90 values with historical values from the literature we update the orbital ephemeris of Her X-1 to T90 = MJD 46359.871940(6) and Porb = 1.700167590(2) d and measure a continuous change of the orbital period of dPorb/dt = -(4.85 +/- 0.13) x 10-11 s/s. For the first time, a value for the eccentricity of the orbit of Her X-1 is measured to be e = (4.2 +/- 0.8) x 10-4.

description: We have investigated the differences in apparent opening angles between the parsec-scale jets of the active galactic nuclei (AGN) detected by the Fermi Large Area Telescope (LAT) during its first three months of operations and those of non-LAT-detected AGN. We used 15.4 GHz VLBA observations of sources from the 2 cm VLBA MOJAVE program, a subset of which comprise the statistically complete flux density limited MOJAVE sample. We determined the apparent opening angles by analyzing transverse jet profiles from the data in the image plane and by applying a model fitting technique to the data in the (u,v) plane. Both methods provided comparable opening angle estimates. The apparent opening angles of gamma-ray bright blazars are preferentially larger than those of gamma-ray weak sources. At the same time, we have found the two groups to have similar intrinsic opening angle distributions, based on a smaller subset of sources. This suggests that the jets in gamma-ray bright AGN are oriented at preferentially smaller angles to the line of sight resulting in a stronger relativistic beaming. The intrinsic jet opening angle and bulk flow Lorentz factor are found to be inversely proportional, as predicted by standard models of compact relativistic jets. If a gas dynamical jet acceleration model is assumed, the ratio of the initial pressure of the plasma in the core region P_0 to the external pressure P_ext lies within the range 1.1 to 34.6, with a best fit estimate of P_0/P_ext=2.

description: We investigated the influence of dark matter on light propagation in the solar system. We assumed the spherical symmetry of spacetime and derived the approximate solution of the Einstein equation, which consists of the gravitational attractions caused by the central celestial body, i.e. the Sun, and the dark matter surrounding it. We expressed the dark matter density in the solar system in the following simple power-law form, $\varrho(t, r) = ρ(t)(\ell/r)^k$, where $t$ is the coordinate time; $r$, the radius from the central body; $\ell$, the normalizing factor; $k$, the exponent characterizing $r$-dependence of dark matter density; and $ρ(t)$, the arbitrary function of time $t$. On the basis of the derived approximate solution, we focused on light propagation and obtained the additional corrections of the gravitational time delay and the relative frequency shift caused by the dark matter. As an application of our results, we considered the secular increase in the astronomical unit reported by Krasinsky and Brumberg (2004) and found that it was difficult to provide an explanation for the observed $d{\rm AU}/dt = 15 \pm 4 ~[{\rm m/century}]$.

description: Corporate executives receive a considerable portion of their compensation in the form of equity and, from time to time, sell a portion of their holdings in the open market. Executives nearly always have access to nonpublic information about the company, and routinely have an information advantage over public shareholders. Federal securities laws prohibit executives from trading on material nonpublic information about their company, and companies develop an Insider Trading Policy to ensure executives comply with applicable rules. In this Closer Look, we examine the potential shortcomings of existing governance practices as illustrated by four examples that suggest significant room for improvement. We ask: Should an ITP go beyond legal requirements to minimize the risk of negative public perception from trades that might otherwise appear suspicious? Why don’t all companies make the terms of their ITP public? Why don’t more companies require the strictest standards, such as pre-approval by the general counsel and mandatory use of 10b5-1 plans? Does the board review trades by insiders on a regular basis? What conversation, if any, takes place between executives and the board around large, single-event sales?

description: We discuss the relation of the specific heat, the energy density and the thermodynamic Casimir effect in the case of thin films in the three dimensional XY universality class. The finite size scaling function $θ(x)$ of the thermodynamic Casimir force can be expressed in terms of the scaling functions h'(x) and h(x) of the excess energy density and the excess free energy density. A priori these quantities depend on the reduced temperature t and the thickness L_0 of the film. However finite size scaling theory predicts that the scaling functions depend only on the combination x=t [L_0/ξ_0]^{1/ν}, where νis the critical exponent and $ξ_0$ the amplitude of the correlation length. We exploit this fact to compute θfrom Monte Carlo data for the excess energy density of the improved two-component ϕ^4 model on the simple cubic lattice with free boundary conditions in the short direction. We repeat this exercise using experimental data for the excess specific heat of 4He films. The finite size scaling behaviour of the excess specific heat is governed by h''(x), which is proportional to the scaling function $f_2$ discussed in the literature. We compare our results with previous work, where the Casimir force has been computed by taking the derivative of the excess free energy with respect to the thickness of the film. As a preparative study we have also computed the scaling functions h'(x) and h(x) for finite L^3 systems with periodic boundary conditions in all directions, where L is the linear extension of the system.

Feature evaluation criteria and contextual decoding algorithms in statistical pattern recognition
Creators: name: Toussaint, Godfried Theodore Patrick
Publisher: name: University of British Columbia
Year: 2011

description: Several probabilistic distance, information, uncertainty, and overlap measures are proposed and considered as possible feature evaluation criteria for statistical pattern recognition problems. A theoretical and experimental analysis .and comparison of these and other well known criteria are presented. A class of certainty measures is proposed that is well suited to pre-evaluation -and intraset post-evaluation. Two approaches to the M-class problem are considered: the well known expected value approach and a proposed generalized distance approach. In both approaches the main distance measures considered are Kullback's divergence, the Bhattacharyya coefficient, and Kolmogorov's variational distance. In addition a generalization of the Bhattacharyya coefficient to the M-class problem is considered. Properties and inequalities are derived for the above measures. In addition, error bounds are derived whenever possible, and it is shown that some of these bounds are tighter than existing ones while others represent generalizations of well known bounds found in the literature. Feature ordering experiments were carried out to compare the above measures with each other and with the Bayes error probability criterion. Finally, some very general measures are proposed which reduce to several of the measures considered above as special cases and error bounds are derived in terms of these measures. A general class of algorithms is proposed for the efficient utilization of contextual dependencies among patterns, at the syntactic level, in the decision process of statistical pattern recognition systems. The algorithms are dependent on a set of parameters which determine the amount of contextual information to be used, how it is to be processed, and the computation and storage required. One of the most important parameters in question, referred to as the depth of search, determines the number of alternatives considered in the decoding process. Two general types of algorithms are proposed in which the depth of search is pre-specified and remains fixed. The efficiency of these algorithms is increased by incorporating a threshold and effecting a variable depth of search that depends on the amount of noise present in the pattern in question. Several general types of algorithms incorporating the threshold are also proposed. In order to experimentally analyze, compare, and evaluate the various algorithms, the recognition of handprinted English text was simulated on a digital computer.
Second-order nonlinear optical effects of spin currents

description: A pure spin current formed by opposite spins moving in opposite directions is a rank-2 axial tensor which breaks the inversion symmetry. Thus a spin current has a second-order optical susceptibility, with unique polarization-dependence determined by the symmetry properties of the current. In particular, a longitudinal spin current, in which the spin polarization directions are parallel or anti-parallel to the moving directions, being a chiral quantity, leads to a chiral sum-frequency effect. Microscopic calculations based on the eight-band model of a III-V compound semiconductor confirm the symmetry analysis and show that the susceptibility is quite measurable under realistic conditions. The second-order nonlinear optical effects may be used for in-situ and non-destructive detection of spin currents, as a standard spectroscopy tool in research of spintronics.

Healthy@work? : Lifestyle factors and workplace health promotion
Creators: name: Kilpatrick, Michelle Louise
Publisher: name: University Of Tasmania

description: Adverse lifestyle factors, such as cigarette smoking, poor diet, risky alcohol consumption, overweight and obesity, physical inactivity and sedentary behaviours, are associated with non-communicable diseases and premature mortality. Evidence from controlled interventions shows that workplaces are settings where employee lifestyle factors can be improved via workplace health promotion (WHP). Less clear is what happens outside of controlled trials, when organisations attempt to implement WHP underpinned by best-evidence principles. In 2009 the Tasmanian State Service invested in a four-year WHP program that targeted its entire workforce. The aims of this thesis were to investigate employee participation in, and the benefits of, the Healthy@Work project. Of particular focus were employee lifestyle factors, including sedentary behaviours, and recommended WHP implementation strategies in practice. The study used a repeated cross-sectional survey design with stratified random samples. Survey data was collected in 2010 (n=3408) and 2013 (n=3228) from Tasmanian State Service employees, and respondent characteristics were similar in both surveys. With regard to implementation, the findings indicated employee needs assessments and health risks are likely to align with employee preferences for programs. Inequitable access to WHP activities, and lower levels of participation in some at risk groups, was evident. Barriers to participation included time, health problems and location of activities. However, recommended implementation practices, and social support, were related to participation in more activities. For lifestyle factors, prolonged sitting at work was found to be associated with psychological distress. Finally, participation in activities related to health behaviours was associated with a range of employee-perceived benefits, such as being motivated or assisted to be physically active, yet population-level differences in lifestyle factors were not observed between 2010 and 2013. Despite observed intermediary benefits, Healthy@Work was either ineffective in regard to achieving measurable behaviour change, or insufficient time had elapsed to detect a population-level shift. Organisations administering WHP should establish clearly defined outcomes and appropriately match expectations, resources and time frames to realising those outcomes.

Enhancing legal pedagogy in undergraduate legal education : teaching ethics, professionalism and critical reflection to law students from the foundation year of law
Creators: name: Hiller, SJ
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis examines the importance of law students developing an understanding of ethics, professionalism and critical reflection from the beginning of tertiary legal education. The thesis shows why, when and how these areas need to be developed. Findings of the research aim to provide legal educators with a toolbox of pedagogical techniques for teaching law students about ethics, professionalism and critical reflection. It suggests areas for further research. The findings of this research can be used by law faculties to embed Threshold Learning Outcomes (TLOs) relating to the areas of ethics, professionalism and critical reflection into legal curriculums to enhance both and accountability to government, the legal profession and the public. The academic literature demonstrates significant ongoing concerns relating to unethical and unprofessional behaviour within the legal profession, the ethical standards required for legal practice and the positive role upholding ethics and professionalism can have for legal practice and promoting social justice. The thesis argues that ethics and professionalism should be taught pervasively from the foundation year through the legal curriculum. Less traditional pedagogical techniques such as the use of popular culture, group work and courtroom experiences are supported to supplement traditional lectures and tutorials. The thesis examines critical reflection in higher education in order to guide and instruct foundation law students about the importance of critical reflection as a legal skill. A multidisciplinary literary review of reflective journaling is provided, demonstrating that the use of journaling is becoming increasingly popular as an effective pedagogical technique, well suited to legal education. The review also shows that other pedagogical techniques can be supplemented with reflective journaling. The positive impact of using interventionist strategies such as guidance, feedback and instruction in the improvement in the structure and depth of critical reflection are revealed. The thesis suggests there is not a dominant reflective model used in the foundation year of legal education. This research, informed by the academic literature therefore develops a cyclical prompt-based model of critical reflection. The research involves an analysis of foundation students' reflective journal texts, from 2009 and 2011 at the University of Tasmania, using constructivist grounded theory and discourse analysis. The analysis reveals what engages and challenges foundation law students, how they like to improve their legal knowledge and skills, the influence of court experiences and popular culture and students' views of ethics and professionalism. The research informed by the academic literature makes a contribution to the development of legal pedagogy in the areas of ethics, professionalism and critical reflection.
