Compliance enforcement in regional fisheries management organisations to which Australia is a party
Creators: name: Clark, EA
Publisher: name: University Of Tasmania
Year: 2023

description: One of the key problems facing regional fisheries management organisations (RFMOs) in the twenty-first century is a lack of compliance by flag States. Non-compliance by both contracting and non-contracting parties to RFMOs threatens the effectiveness of a regime which relies almost entirely upon cooperation and the interests of individual States to function. The political will of States to effectively address problems caused by non-compliance including, inter alia, illegal, unreported and unregulated (IUU) fishing, has recently been deemed wanting. This thesis is concerned with the need for better implementation of compliance enforcement mechanisms by RFMOs to which Australia is a party (AusRFMOs). It examines the range of compliance enforcement mechanisms available to RFMOs and evaluates how AusRFMOs are currently tackling the problem of non-compliance. It recognises the difficulties faced by RFMOs in implementing their mandate and demonstrates that policy and diplomatic avenues along with a range of countermeasures may be, and have been, evoked by RFMOs to tackle flag State noncompliance. This thesis concludes that AusRFMOs could improve their compliance enforcement across the board. It demonstrates that despite the widespread adoption of mechanisms such as IUU vessel lists, there remains a gap between the theoretical mandate of these organisations and their adoption of measures to enable more effective enforcement. The thesis submits that AusRFMOs must better utilise their enforcement capabilities if they are to fulfil the role envisaged for them under the United Nations Convention on the Law of the Sea and other associated international agreements. It concludes that AusRFMOs should take steps to move beyond their role as cooperative entities towards an enforcement capacity if they are to make a real contribution to achieving sustainable global fisheries.

description: While network coding can be an efficient means of information dissemination in networks, it is highly susceptible to "pollution attacks," as the injection of even a single erroneous packet has the potential to corrupt each and every packet received by a given destination. Even when suitable error-control coding is applied, an adversary can, in many interesting practical situations, overwhelm the error-correcting capability of the code. To limit the power of potential adversaries, a broadcast transformation is introduced, in which nodes are limited to just a single (broadcast) transmission per generation. Under this broadcast transformation, the multicast capacity of a network is changed (in general reduced) from the number of edge-disjoint paths between source and sink to the number of internally-disjoint paths. Exploiting this fact, we propose a family of networks whose capacity is largely unaffected by a broadcast transformation. This results in a significant achievable transmission rate for such networks, even in the presence of adversaries.

description: Magnetization M(T,H) measurements performed on thoroughly characterized commercial amorphous carbon powder doped with sulfur (AC-S), revealed the occurrence of an inhomogeneous superconductivity (SC) below T_c = 38 K. The constructed magnetic field-temperature (H-T) phase diagram resembles that of type-II superconductors. However, AC-S demonstrates a number of anomalies. In particular, we observed (1) a non-monotonic behavior of the lower critical field H_c1(T); (2) a pronounced positive curvature of the "upper critical field boundary" that we associated with the flux lattice melting line Hm(T); (3) a spontaneous ferromagnetic-like magnetization M0 coexisting with SC. Based on the analysis of experimental results we propose a nonstandard SC state in AC-S.

description: This paper deals with the early results of a new model of pedestrian flow, conceived within a measure-theoretical framework. The modeling approach consists in a discrete-time Eulerian macroscopic representation of the system via a family of measures which, pushed forward by some motion mappings, provide an estimate of the space occupancy by pedestrians at successive time steps. From the modeling point of view, this setting is particularly suitable to treat nonlocal interactions among pedestrians, obstacles, and wall boundary conditions. In addition, analysis and numerical approximation of the resulting mathematical structures, which is the main target of this work, follow more easily and straightforwardly than in case of standard hyperbolic conservation laws, also used in the specialized literature by some Authors to address analogous problems.

description: Furanic di-carboxylate derivatives of 5-Hydroxymethylfurfural (HMF) are nowadays important in the polymer industry as they are used as building blocks for bio-based polyesters. The high reactivity of HMF compels to avoid harsh synthetic conditions. Therefore, developing mild catalytic processes for its selective oxidation is a challenging task. Herein, we report the first oxidative esterification of HMF to dimethyl furan-2,5-dicarboxylate (FDCM) under flow conditions using oxygen as oxidant. For that purpose, a new series of nitrogen-doped carbon-supported bimetallic Co/Ru heterogeneous catalysts were prepared and characterized by XRD, XPS and N2 physisorption. These analyses revealed that the porosity of the materials and order of impregnation of the metals to the carbon supports lead to varying catalytic activities. Under optimized conditions the flow reactor showed a 15-fold increase on the production of FDCM compared to batch conditions. © 2020 The Authors. Published by Wiley-VCH Verlag GmbH & Co. KGaA.

description: We construct asymptotically AdS_5 solutions of Einstein-Maxwell theory dual to N=4 SYM theory on R^{3,1} in the presence of a background magnetic field. The solutions interpolate between AdS_5 and a near horizon AdS_3\times T^2. The central charge of the near horizon region, and hence low temperature entropy of the solution, is found to be \sqrt{4\over 3} times that of free N=4 SYM theory. The entropy vanishes at zero temperature. We also present the generalization of these solutions to arbitrary spacetime dimensionality.

description: We present particulate simulation results for translational and rotational friction components of a shish-kebab model of a colloidal rod with aspect ratio (length over diameter) $L/D = 10$ in the presence of a planar hard wall. Hydrodynamic interactions between rod and wall cause an overall enhancement of the friction tensor components. We find that the friction enhancements to reasonable approximation scale inversely linear with the closest distance $d$ between the rod surface and the wall, for $d$ in the range between $D/8$ and $L$. The dependence of the wall-induced friction on the angle $θ$ between the long axis of the rod and the normal to the wall is studied and fitted with simple polynomials in $\cos θ$.

description: The quark propagator is calculated in the Nambu-Jona-Lasinio (NJL) model in a self-consistent 1/Nc-expansion at next-to-leading order. The calculations are carried out iteratively in Euclidean space. The chiral quark condensate and its dependence on temperature and chemical potential is calculated directly and compared with the mean-field results. In the chiral limit, we find a second-order phase transition at finite temperature and zero chemical potential, in agreement with universality arguments. At zero temperature and finite chemical potential, the phase transition is first order. In comparison with the mean-field results, the critical temperature and chemical potential are slightly reduced. We determine spectral functions from the Euclidean propagators by employing the Maximum-Entropy-Method (MEM). Thereby quark and meson masses are estimated and decay channels identified. For testing this method, we also apply it to evaluate perturbative spectral functions, which can be calculated directly in Minkowski space. In most cases we find that MEM is able to reproduce the rough features of the spectral functions, but not the details.

description: High-resolution temperature measurements are required in the LTP, i.e., 10 uK/sqrt(Hz) from 1 mHz to 30 mHz. This has been already accomplished with thermistors and a suitable low noise electronics. However, the frequency range of interest for LISA goes down to 0.1 mHz. Investigations on the performance of temperature sensors and the associated electronics at frequencies around 0.1 mHz have been performed. Theoretical limits of the temperature measurement system and the practical on-ground limitations to test them are shown demonstrating that 1/f noise is not observed in thermistors even at frequencies around 0.1 mHz and amplitude levels of 10 uK/sqrt(Hz).

description: In this work we study the Double Exchange-Holstein (DE-H) model with an electron-phonon interaction $γ$ coupled to magnetism. The analysis is performed combining a mean-field approximation for the double exchange interaction and the Lang-Firsov transformation for the electron-phonon interaction. Discontinuous magnetic transitions appear when the dependence of $g$ with $m$ is sufficiently large, resembling those experimentally observed in manganites. We observe that the characteristic resistivity peak that arises near the critical temperature appears for broad ranges of the system parameter values, unlike what occurs in a constant--$γ$ model.

Electronic states of trans-polyacetylene, poly(p-phenylene vinylene) and sp-hybridised carbon species in amorphous hydrogenated carbon probed by resonant Raman scattering

description: Inclusions of sp-hybridised, trans-polyacetylene [trans-(CH)x] and poly(p-phenylene vinylene) (PPV) chains are revealed using resonant Raman scattering (RRS) investigation of amorphous hydrogenated carbon (a-C:H) films in the near IR - UV range. The RRS spectra of trans-(CH)x core Ag modes and the PPV CC-H phenylene mode are found to transform and disperse as the laser excitation energy \hbarωL is increased from near IR through visible to UV, whereas sp-bonded inclusions only become evident in UV. This is attributed to \hbarωL probing of trans-(CH)x chain inhomogeneity and the distribution of chains with varying conjugation length; for PPV to the resonant probing of phelynene ring disorder; and for sp segments, to \hbarωL probing of a local band gap of end-terminated polyynes. The IR spectra analysis confirmed the presence of sp, trans-(CH)x and PPV inclusions. The obtained RRS results for a-C:H denote differentiation between the core Ag trans-(CH)x modes and the PPV phenylene mode. Furthermore, it was found that at various laser excitation energies the changes in Raman spectra features for trans-(CH)x segments included in an amorphous carbon matrix are the same as in bulk trans-polyacetylene. The latter finding can be used to facilitate identification of trans-(CH)x in the spectra of complex carbonaceous materials.

We invoke a generalization of the principle of local symmetry to provide a criterion for path selection and demonstrate qualitative agreement with the experimental findings. The nature of the singularity at the crack tip is studied with and without the interference of nonlinear terms.

The Monstrous Encounter
Creators: name: Kirsopp, E
Publisher: name: University Of Tasmania
Year: 2023

description: This research project proposes that the monstrous encounter in art, film and story can\ signify the change from the understood to the unknown self, using the historical context\ and literary elements of Little Red Riding Hood as a framework. Within this framework\ three visual artists, Kiki Smith, Jazmina Cininas and Matthew Barney are investigated\ to demonstrate how the monstrous encounter signifies the change from the understood to the unknown self.\ In order to use Little Red Riding Hood as a framework the historical context of the tale\ has been broken down into three periods, identified as the original, the bourgeois and\ the contemporary. In each period it is shown how the monstrous encounter signifies the\ change from the understood to the unknown self.\ The research project draws on the work of Jack Zipes, The Trials and Tribulations of\ Little Red Riding Hood (1993) and Fairy Tales and the Art of Subversion (1983); Jon\ Elster, The Multiple Self (1985); Barbara Creed, The Monstrous Feminine (1993) and\ Phallic Panic (2005); and Julia Kristeva, Powers of Horror (1982). These key\ references are used to define important ideas and strengthen terminology specific to the\ project, such as self, monster and monstrous encounter, abjection and transformation.\ As a result of using Little Red Riding Hood as a framework the majority of the research\ looks at the monstrous encounter almost exclusively in the form of lycanthropy, which\ lends itself most easily to concepts of metamorphoses and the div ided self. The\ werewolf enjoys enormous popularity in many avenues of contemporary culture and\ there exists countless references to this particular genre of monstrous encounter.\ However, this is not a project about werewolves but an investigation of the monstrous\ encounter, whatever form it takes. Whether it is an internal event like the work of\ Matthew Barney or an external process as in Cininas's use of Angela Carter's\ contemporary Red Riding Hood, the monstrous encounter in art, film and story can be\ demonstrated to signify the change from the understood to the unknown self.

description: Ultracold atomic gases in optical lattices have proven to be a controllable, tunable and clean implementation of strongly interacting quantum many-body systems. An essential prospect for such quantum simulators is their ability to map out the phase diagram of fundamental many-body model Hamiltonians. However, the results need to be validated first for representative benchmark problems via state-of-the-art numerical methods of quantum many-body theory. Here we present the first ab-initio comparison between experiments and quantum Monte Carlo simulations for strongly interacting Bose gases on a lattice for large systems (up to N = 3e5 particles). The comparison has enabled us to perform thermometry for the interacting quantum gas and to experimentally determine the finite temperature phase diagram for bosonic superfluids in an optical lattice. Our results reveal a downshift of the critical temperature as the transition to the Mott insulator is approached.
Developing student's understandings and representations of statistical covariation
Creators: name: Moritz, J
Publisher: name: University Of Tasmania
Year: 2023

description: Statistical covariation refers to the correspondence of variation of two statistical measures that vary along numerical scales. Reasoning about covariation commonly involves translation processes among three representations: (1) numerical data, (2) graphical representations, and (3) verbal statements such as "taller people tend to be heavier". Two well-known translations are graph production and graph interpretation. Less well known is the process of speculative data generation, involving translating a verbal statement into a possible graph or other data representation. This study explored school students' reasoning involving these three translation skills through various tasks in surveys and interviews. Evidence is presented concerning methods to assess these skills, and concerning how students as young as third-grade can engage covariation tasks involving familiar contexts. Interviews involved prompting for cognitive conflict using responses from other students, and provided evidence of limited engagement of ideas that were slightly more sophisticated than their own responses. Responses for each of the three translation skills were described within assessment frameworks involving four levels - Nonstatistical, Single Statistical Aspect, Inadequate Covariation, and Appropriate Covariation - distinguished by the structure of combining correspondence and variation. Distinguishing features of the levels suggested stages of development that may inform instruction. For development from prior beliefs to data-based judgements, tasks involving counterintuitive covariation were designed to prompt students to engage data. For development from single variables to bivariate data, time was observed as a natural covariate, implicit in statements such as "it's getting hotter", with a connotation of order that supported pattern recognition of passing time being associated with corresponding change in a measured variable. For development from single cases to global trends, many students represented correspondence in a single pair of values, at the expense of representing variation. Tasks involving discrete data with few cases, and the use of case labels in responses, were observed to support the view of two data values each linked to the same corresponding case label. This consolidated view of correspondence supported consideration of additional bivariate cases involving variation. Students tended to articulate covariation using the language of comparison and change. Findings were related to issues in the historical development of coordinate graphing, to findings from educational research in statistics, algebra, science and psychology, and to recommendations within curriculum documents. Student representations of statistical covariation were observed to provide a window into statistical reasoning, and are advocated as a valuable basis for classroom discussions to help develop statistical literacy.

Sustainable Development Goals

description: The potential of open science is vast and profound and goes far beyond the sharing of the outputs of research. At its core, it promotes the concept of sharing research, building on cumulative results, largely based on the verification of previous results, thanks in the main to the plethora of digital technologies. This ultimately leads to a radical transformation of the culture of research. Open science has the ability to change the ways in which research is performed via its inputs and sources, in its collaborations and partnerships, in how, and how quickly, it is accessed and applied. It can embrace diverse and inclusive modes of communication, dialogue and engagement, in how research is validated and reviewed, and in new, richly-enhanced and deeply-interconnected types of outputs. The pursuit and application of knowledge in the service of the grand challenges facing humanity is a truly global endeavour. Science can only succeed in this context when it is openly shared and accessible by all. Science ‘done right’, through open science can transform society by opening up access to knowledge via the free flow of information. This, in turn, maximises the societal and economic impact of research for the global benefit of humanity and of the planet. Open science is, therefore, a fundamental foundation of the UN Sustainable Development Goals and constitutes a cross-cutting contribution to the achievement of those Goals. For this reason, OpenAIRE fully supports UNESCO’s call to develop global open science principles and endorses UNESCO’s efforts to promote and achieve open science.

description: We present the Bayesian analysis of four different types of backreation models, which are based on the Buchert equations. In this approach, one considers a solution to the Einstein equations for a general matter distribution and then an average of various observable quantities is taken. Such an approach became of considerable interest when it was shown that it could lead to agreement with observations without resorting to dark energy. In this paper we compare the LambdaCDM model and the backreation models with SNIa, BAO, and CMB data, and find that the former is favoured. However, the tested models were based on some particular assumptions about the relation between the average spatial curvature and the backreaction, as well as the relation between the curvature and curvature index. In this paper we modified the latter assumption, leaving the former unchanged. We find that, by varying the relation between the curvature and curvature index, we can obtain a better fit. Therefore, some further work is still needed -- in particular the relation between the backreaction and the curvature should be revisited in order to fully determine the feasibility of the backreaction models to mimic dark energy.

description: In this paper a holographic description of eternal inflation is developed. We focus on the description of an open FRW universe that results from a tunneling event in which a false vacuum with positive vacuum energy decays to a supersymmetric vacuum with vanishing cosmological constant. The observations of a "Census Taker" in the final vacuum can be organized into a holographic dual conformal field theory that lives on the asymptotic boundary of space. We refer to this bulk-boundary correspondence as FRW/CFT duality. The dual CFT is a Euclidean two-dimensional theory that includes a Liouville 2-D gravity sector describing geometric fluctuations of the boundary. The RG flow of the theory is richer than in the ADS/CFT correspondence, and generates two space-time dimensions--one space-like and one time-like. We discuss a number of phenomena such as bubble collisions, and the Garriga, Guth, Vilenkin "persistence of memory," from the dual viewpoint.

description: The $\cal PT$-symmetric complexified Scarf II potential $V(x)= - V_1 \sech^{2}x + {\rm i} V_2 \sech x \tanh x$, $V_1>0$ , $V_{2}\neq 0$ is revisited to study the interplay among its coupling parameters. The existence of an isolated real and positive energy level that has been recently identified as a spectral singularity or zero-width resonance is here demonstrated through the behaviour of the corresponding wavefunctions and some property of the associated pseudo-norms is pointed out. We also construct four different rationally-extended supersymmetric partners to $V(x)$, which are $\cal PT$-symmetric or complex non-$\cal PT$-symmetric according to the coupling parameters range. A detailed study of one of these partners reveals that SUSY preserves the $V(x)$ spectral singularity existence.

description: We discuss general on-shell couplings of a scalar with two Z bosons using an operator analysis. In addition to the operator originated from the Higgs mechanism, two dimension-five operators, one CP-even and one CP-odd, are generated only at the loop-level. Simple formulas are derived for the differential decay distributions when the Z pair subsequently decay into four leptons by computing the helicity amplitudes, from which it is shown the CP-odd operator merely induces a phase shift in the azimuthal angular distribution between the two decay planes of the Z bosons. We also investigate new physics scenarios giving rise to loop-induced decays of a scalar into ZZ pair, and argue that the total decay width of such a scalar would be order-of-magnitude smaller than that of a Higgs boson, should such decays be observed in the early running of the LHC. Therefore, the total decay width alone is a strong indicator of the Higgs nature, or the lack thereof, of a scalar resonance in ZZ final states. In addition, we study the possibility of using the azimuthal angular distribution to disentangle effects among all three operators.

description: By integrating data on scientific publications from the RISIS publication database with data on European Universities from the European Tertiary Education Register and data on US universities, researchers from USI, Lugano, and from the University of Turin have shown a strong relationship between universities’ revenues and their volume of publications and citations. This relationship implies that international rankings are largely by and large measures of wealth. Further, the study shows that three characteristics differentiate the US system, i.e. a) a significantly higher level of resources, b) a clearer distinction between education-oriented institutions and doctoral universities, and c) a higher concentration of resources among doctoral universities Accordingly, a group of US universities receive a much larger amount of resources and have a far higher number of publications and citations when compared to their European counterparts. These results demonstrate that the ‘transatlantic gap’ in research excellence is largely associated with differences in resources. Implications for public policies and institutional evaluation are discussed.

description: On Friday 29th of May, the 3RD RISIS POLICYMAKERS SESSION entitled “A comparison of US and European Universities: the strong relationship between revenues and excellence” took place in an online format because of the Covid-19 emergency. The conference focused on the results of a recent study published on PlosOne, and titled Scientific output scales with resources. A comparison of US and European Universities, conducted by Università della Svizzera italiana in collaboration with the University of Turin. By integrating data on scientific publications from the CWTS Publication Database with data on European Universities from RISIS-ETER (European Tertiary Education Register) researchers from USI, Università della Svizzera Italiana in cooperation with University of Turin demonstrated a strong relationship between universities revenues and their volume of publication and citations. The conference begun with an Opening of DR Emanuela Reale, Director of the Research Institute on Sustainable Economic Growth, National Research Council of Italy, mainly focused on RISIS project and its priorities. DR Benedetto Lepori from Università della Svizzera Italiana illustrated in the central session of the conference the main results of the research in his presentation titled Best Universities behind rankings. Finally, Dr Sumathi Subramaniam, DG Education, Youth, Sport and Culture, Policy Officer in the Unit for Policy on Higher Education (European Commission) focused on policy implications and offered a valuable contribution on resources allocation in Higher Education, illustrating the several actions conducted by the European Commission to enhance the development in funding in HEis.

Management strategies for an input controlled fishery based on the capture of short-lived tropical species : the example of Australia's northern prawn fishery
Creators: name: Dichmont, CM
Publisher: name: University Of Tasmania
Year: 2023

description: The NPF is one of the Australian Commonwealth's most valuable fisheries. The species groups targeted include tiger, banana and endeavour prawns. The fishery is managed using input controls and, from 2001 until 2004 (the period which spans this study), the agreed target was for the level of fishing effort expended to lead to a 70% chance (or greater) that the spawning stock size of tiger prawns was at or above that corresponding to Maximum Sustainable Yield, SMSY. A key issue in the management of this fishery is that the efficiency of fishing effort is continually increasing so that past effort reductions have been fully offset by improved efficiencies. In fact, some past effort reductions did not actually lead to a real reduction in effective effort. As a consequence of this, there was no recovery in the size of the tiger prawn resource but rather, in some years, a decline, until a major effort reduction program was implemented in 2001.
Population genetics of selected whitebait species : Galaxias maculatus (Jenyns) and Lovettia sealii (Johnston).

description: Population Genetics of Selected Whitebait Species: Galaxias maculatus (Jenyns) and Lovettia sealii (Johnston). Populations of diadromous G. maculatus and anadromous L. sealii fishes have been studied for genetic variation by cellulose acetate electrophoresis. L. sealii is a small member of the family Aplochitonidae endemic to Tasmania. In contrast, G. maculatus a salmoniform fish of the Family Galaxiidae, is found throughout the southern temperate zone (Australia, New Zealand and South America). Together these species are the predominant components of Tasmanian whitebait. A significant commercial fishery for Tasmanian whitebait began in 1941 and rapidly declined after 1947 probably due to overfishing (Blackburn, 1950), until its closure in 1974. Encouraging runs of whitebait in the early 1980s prompted a major study to investigate the potential yield and present status of this resource. The lack of data regarding the genetic structure of the species prompted the following study. Eight populations of G. maculatus extending from Western Australia to New Zealand were investigated. Twenty seven samples of L. sealii representing thirteen different river populations from Tasmania were included to capture genetic data both within and between three successive spawning seasons. An analysis of the gene frequency data using Nei's genetic distance (D) and identity (I) , G-test and F-statistics indicated population substructuring in the two species. Morphometric and meristic analysis of L. sealii was also undertaken and supported the genetic data. Within G. maculatus, the Western Australian population was genetically distinct primarily based on allele frequencies observed at the ADH locus. Three genetic pools of G. maculatus were identified which have zoo-geographic implications for this species. In particular they appear to confirm the potential of marine larval dispersal between Australia and New Zealand. A clear genetic discontinuity was observed between north and south Tasmanian L. sealii primarily based on the allele frequency data at the PEPD locus. These fmdings were consistent with those of Blackburn (1950) based on differences in growth rate and pigmentation. However, many southern rivers were found to carry unique stocks. A major contributing factor to this genetic diversity is thought to be the prevailing local hydrographic conditions. The results of this study have implications for the management of the recreational whitebait fishery which has re-opened in Tasmania and possibly the commercial whitebait fishery in New Zealand which is dominated by G. maculatus.

description: Alkyne complexes with vicinal substitution by a Lewis acid and a Lewis base at the coordinated alkyne are prospective frustrated Lewis pairs exhibiting a particular mutual distance and, hence, a specific activation potential. In this contribution, investigations on the generation of a WII alkyne complex bearing a phosphine as Lewis base and a carbenium group as Lewis acid are presented. Independently on potential substrates added, an intramolecular cyclisation product was always isolated. A subsequent deprotonation step led to an unprecedented side-on λ5-phosphinyne complex, which is interpreted as highly zwitterionic according to visible absorption spectroscopy supported by TD-DFT. Low-temperature 31P NMR and EPR spectroscopic measurements combined with time-dependent IR-spectroscopic monitoring provided insights in the mechanism of the cyclisation reaction. Decomposition of the multicomponent IR spectra by multivariate curve resolution and a kinetic hard-modelling approach allowed the derivation of kinetic parameters. Assignment of the individual IR spectra to potential intermediates was provided by DFT calculations. © 2020 The Authors. Published by Wiley-VCH GmbH
