description: Excerpts from the report: Frozen food locker plants operating in the United States in January 1959 totaled 9,271. This is a decline of 340 plants from last year. Iowa again led with 678 plants, Minnesota came second with 598, and Washington third with 590. South Dakota, Wisconsin, Texas, and Washington registered the greatest decline in number of plants -- 63, 57, 37, and 36, respectively. While the number of locker plants has declined by about 2,300 since the peak year of 1951, many hundreds of new "Freezer Provisioner" or "Freezer Food Plan" enterprises have been established during recent years. The volume of food processed and sold and the number of customers served has been substantially increased.
Large-scale second RPA calculations with finite-range interactions

Subjects: subject: Nuclear Theory (nucl-th)

description: Second RPA (SRPA) calculations of nuclear response are performed and analyzed. Unlike in most other SRPA applications, the ground state, approximated by the Hartree-Fock (HF) ground state, and the residual couplings are described by the same Hamiltonian and no arbitrary truncations are imposed on the model space. Finite-range interactions are used and thus divergence problems are not present. We employ a realistic interaction, derived from the Argonne V18 potenial using the unitary correlation operator method (UCOM), as well as the simple Brink-Boeker interaction. Representative results are discussed, mainly on giant resonances and low-lying collective states. The focus of the present work is not on the comparison with data, but rather on technical and physical aspects of the method. We present how the large-scale eigenvalue problem that SRPA entails can be treated, and demonstrate how the method operates in producing self-energy corrections and fragmentation. The so-called diagonal approximation is conditionally validated. Stability problems are traced back to missing ground-state correlations.

description: We study the problem of minimizing the second Dirichlet eigenvalue for the Laplacian operator among sets of given perimeter. In two dimensions, we prove that the optimum exists, is convex, regular, and its boundary contains exactly two points where the curvature vanishes. In $N$ dimensions, we prove a more general existence theorem for a class of functionals which is decreasing with respect to set inclusion and $γ$ lower semicontinuous.

description: In this paper we study the possibility of sustaining an evolving wormhole via exotic matter made out of phantom energy. We show that this exotic source can support the existence of evolving wormhole spacetimes. Explicitly, a family of evolving Lorentzian wormholes conformally related to another family of zero-tidal force static wormhole geometries is found in Einstein gravity. Contrary to the standard wormhole approach, where first a convenient geometry is fixed and then the matter distribution is derived, we follow the conventional approach for finding solutions in theoretical cosmology. We derive an analytical evolving wormhole geometry by supposing that the radial tension (which is negative to the radial pressure) and the pressure measured in the tangential directions have barotropic equations of state with constant state parameters. At spatial infinity this evolving wormhole, supported by this anisotropic matter, is asymptotically flat, and its slices $t=$ constant are spaces of constant curvature. During its evolution the shape of the wormhole expands with constant velocity, i.e without acceleration or deceleration, since the scale factor has strictly a linear evolution.

description: The paper studies the problem of the cofibrant generation of a model category. We prove that, assuming Vopěnka's principle, every cofibrantly generated model category is Quillen equivalent to a combinatorial model category. We discuss cases where this result implies that the class of weak equivalences in a cofibrantly generated model category is accessibly embedded. We also prove a necessary condition for a model category to be cofibrantly generated by a set of generating cofibrations between cofibrant objects.

Science fiction texts, gender and transformation
Creators: name: Coleman, MJ
Publisher: name: University Of Tasmania
Year: 2023

description: This research reignites the debates on gender in education and how constructions of gender can be transformed within texts. It analyses the gendered constructions, which are present in students' science fiction texts and how students use transformative critical thinking to challenge and change those gendered constructions. Transformative analysis questions (Rowan, 2001) are used by students to question and deconstruct the gendered constructions in science fiction texts. The literature review examines how popular culture and science fiction texts construct gender. It then explores critical literacy pedagogy and the transformative analysis questions approach by Rowan (2001). Poststructuralist feminist theory frames the research design and analysis. This research uses constructivist grounded theory (Charmaz, 2000, 2005, 2006) and critical discourse analysis (Fairclough, 1992, 2001, 2009) to code and analyse gender in Version 1 and Version 2 of the Students' Science Fiction Texts. The discourses were examined using critical discourse analysis (Fairclough, 1992, 2001, 2009). The dominant discourses of Version 1 and 2 of the Students' Science Fiction Texts were explored to view how students constructed gender in traditional hegemonic ways. Two dominant discourses were explored for transformation. A major finding of this research was that students transformed their versions of gender in their texts. Using Rowan's (2001) transformative analysis questions on science fiction texts, through the teaching of a unit of work, demonstrated the students' ability to deconstruct and transform texts The unit of work using a critical literacy/transformational pedagogy proved a valuable way to teach students how texts can be transformed in socially equitable ways. This research suggests the need for further research to be undertaken to explore gendered constructions using critical literacy pedagogies in schools.
New results on the hadronic vacuum polarization to the muon g-2

description: Results on the lowest-order hadronic vacuum polarization contribution to the muon magnetic anomaly are presented. They are based on the latest published experimental data used as input to the dispersion integral. Thus recent results on tau to nutau pi pi0 decays from Belle and on e+ e- annihilation to pi+ pi- from BABAR and KLOE are included. The new data, together with improved isospin-breaking corrections for tau decays, result into a much better consistency among the different results. A discrepancy between the Standard Model prediction and the direct g-2 measurement is found at the level of 3 sigma.

Year: 2008
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We simulate lattice models in the three-dimensional XY universality class in the low and the high temperature phase. This allows us to compute a number of universal amplitude ratios with unprecedented precision: R_Υ=0.411(2), R_B=2.83(1), R_ξ^+=0.3562(10) and R_ξ^-=0.850(5). These results can be compared with those obtained from other theoretical methods, such as field theoretic methods or the high temperature series expansion and also with experimental results for the lambda-transition of $^4$He. In addition to the XY model, we study the three-dimensional two-component $ϕ^4$ model on the simple cubic lattice. The parameter of the $ϕ^4$ model is chosen such that leading corrections to scaling are small.

description: We present the QSO luminosity function of the completed 2dF-SDSS LRG and QSO (2SLAQ) survey, based on QSOs photometrically selected from Sloan Digital Sky Survey imaging data and then observed spectroscopically using the 2dF instrument on the Anglo-Australian Telescope. We analyse 10637 QSOs in the redshift range 0.420.0, as found previously by Richards et al. (2005). The luminosity function is consistent with other previous, much smaller, samples produced to the depth of 2SLAQ. By combining the 2SLAQ and SDSS QSO samples we produce a QSO luminosity function with an unprecedented combination of precision and dynamic range. With this we are able to accurately constrain both the bright and faint ends of the QSO LF. While the overall trends seen in the evolution of the QSO LF appear similar to pure luminosity evolution, the data show very significant departures from such a model. Most notably we see clear evidence that the number density of faint QSOs peaks at lower redshift than bright QSOs: QSOs with Mg>-23 have space densities which peak at z<1, while QSOs at Mg2. By fitting simple luminosity function models in narrow Mg intervals we find that this downsizing is significant at the 99.98 per cent level (abridged).

An exploratory study of the effect of co-operative group learning, involving tutoring, on the achievement and attitudes of grade eight pupils in new mathematics
Creators: name: Murphy, Patrick Aloysius
Publisher: name: University of British Columbia
Year: 2011

description: An exploratory investigation into the effect of co-operative group learning, involving tutoring, on the achievement and attitudes of 174 grade eight pupils in new mathematics is described. Three volunteer teachers and six volunteered mathematics classes were involved. Five hypotheses concerning test performance and one concerning attitudes were advanced. Using the scores obtained in the mathematics sections of the Stanford Achievement Test (Advanced) and an entering behaviour test of prior mathematics learning, to establish similarity of the groups, instruction was carried out over a period of twelve weeks. A retention test was given two months later. Attitude scores from data collected by Semantic Differential before and after the experiment were analysed using a model for multidimensional analysis of Semantic Differential attitude data (McKie and Foster, 1972). Achievement in algebra learning and retention reached the .05 level of statistical significance, favouring the experimental group. No differences for treatment occurred for instructor effects, instructor by group interaction or attitudes at the .05 level of statistical significance. Conclusions for further research and practice are drawn.

description: A new method to constrain the cosmological equation of state is proposed by using combined samples of gamma-ray bursts (GRBs) and supernovae (SNeIa). The Chevallier-Polarski-Linder parameterization is adopted for the equation of state in order to find out a realistic approach to achieve the deceleration/acceleration transition phase of dark energy models. We find that GRBs, calibrated by SNeIa, could be good distance indicators capable of discriminating between cosmological models and $Λ$CDM model at high redshift.

Stage-coach enterprises in Van Diemen's Land and Tasmania
Creators: name: Walker, S
Publisher: name: University Of Tasmania
Year: 2023

description: From 1820, increased settler movement into Van Diemen's Land prompted the need for improved communications; but small population numbers and high commercial risk factors discouraged the establishment of inland passenger transport enterprises. After 1830, population growth near the two main towns, and the colonial Post Office's evolving inland communications route structure, encouraged transport infrastructure and stage-coach enterprise development, as physical and financial security became more assured. ‚ÄövÑvâ The financially constrained colonial government, transitioning from penal, through self-governing colony to federation, was reluctant to operate businesses where private enterprise might provide the means. Instead, where possible, it subsidised construction, contracted for services, devolved responsibility to local communities, and enacted a comprehensive body of legislation to achieve these ends. Government and stage-coach enterprises alike faced commercial uncertainty caused by economic depressions, the high cost of capital, a reduction in wages, and from outflows of free citizens. Adjustment was necessary following the introduction of steam-powered ferries, the electric telegraph and the railways; population growth was slow and only the opening of new mines increased the potential passenger transport market. The skills required by managers within a convict/free settler society in the face of such economic, financial, legal, social, and workforce uncertainty and complexity were considerable. Yet settlers with capital were primarily interested in land acquisition, and not in service industries. Therefore, stage-coach entrepreneurs were drawn from a free-settler, lower socio-economic group, or from convict expirees with limited business skills, and insolvency was a constant risk. Monopoly of both the route and the logistic support chain was a perceived means towards viability, but was unpopular with government and the press. The large numbers of confident and energetic, yet ordinary, men and women within the stage-coach enterprises, served their communities, and made a considerable contribution to the island's social development, inclusion and capital, and to its economy; yet they are historiographically unnoticed.

Fisher Renormalization for Logarithmic Corrections

Year: 2008
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: For continuous phase transitions characterized by power-law divergences, Fisher renormalization prescribes how to obtain the critical exponents for a system under constraint from their ideal counterparts. In statistical mechanics, such ideal behaviour at phase transitions is frequently modified by multiplicative logarithmic corrections. Here, Fisher renormalization for the exponents of these logarithms is developed in a general manner. As for the leading exponents, Fisher renormalization at the logarithmic level is seen to be involutory and the renormalized exponents obey the same scaling relations as their ideal analogs. The scheme is tested in lattice animals and the Yang-Lee problem at their upper critical dimensions, where predictions for logarithmic corrections are made.

The quasi-2D character of antiferromagnetic spin fluctuations in the paramagnetic state at $P$ = 0 evolves into a 3D character because of the suppression of antiferromagnetic order for $P > P_{\rm QCP}\sim$ 1.36 GPa (QCP: antiferromagnetic quantum critical point). Nuclear-spin-lattice-relaxation rate $1/T_1$ measurements revealed that the superconducting order occurs in the $P$ range 1.36 -- 1.84 GPa, with maximum $T_c\sim$ 0.9 K around $P_{\rm QCP}\sim$ 1.36 GPa.

description: Very-high-energy (VHE; >~100 GeV) gamma-rays are expected from gamma-ray bursts (GRBs) in some scenarios. Exploring this photon energy regime is necessary for understanding the energetics and properties of GRBs. GRBs have been one of the prime targets for the H.E.S.S. experiment, which makes use of four Imaging Atmospheric Cherenkov Telescopes (IACTs) to detect VHE gamma-rays. Dedicated observations of 32 GRB positions were made in the years 2003-2007 and a search for VHE gamma-ray counterparts of these GRBs was made. Depending on the visibility and observing conditions, the observations mostly start minutes to hours after the burst and typically last two hours. Results from observations of 22 GRB positions are presented and evidence of a VHE signal was found neither in observations of any individual GRBs, nor from stacking data from subsets of GRBs with higher expected VHE flux according to a model-independent ranking scheme. Upper limits for the VHE gamma-ray flux from the GRB positions were derived. For those GRBs with measured redshifts, differential upper limits at the energy threshold after correcting for absorption due to extra-galactic background light are also presented.

Properties of age structure models for harvested populations with applications to yellowfin tuna Thunnus albacares (Bonaterre) and harp seals Pagophilus groenlandicus (Erxleben)
Creators: name: Allen, Robin Leslie
Publisher: name: University of British Columbia
Year: 2011

description: Dynamic population models that incorporate the age structure of the population can be used as a powerful tool for fisheries management. In this thesis some of the properties and potential uses of a class of these models is examined. This class can be described as a life table operating on a population with a stock-recruit relation that is formed by multiplying the egg production by a function of a linear combination of the numbers of fish of different ages. The study of the properties included an analysis of the stability and the non-equilibrium behaviour of the model. This behaviour was related to some types of fluctuations observed in fish populations, special attention was given to the limit cycles that occur in populations with an unstable equilibrium and this is considered as a possible a mechanism causing the regular fluctuations known as cyclic dominance in sockeye salmon Oncorhyncus nerka (Walbaum). The fisheries for yellowfin tuna in the eastern Pacific Ocean, and harp seals in the western North Atlantic were used as examples to show how these models might be used by a management body. In the case of the yellowfin tuna the model agreed with results obtained using surplus production models and in addition suggested it is possible to increase both catch and catch per unit effort by changing the open season from the beginning of the year to later in the year. The yield could also be increased by using a fishing method that increased the age of first capture. However, this would suffer from the disadvantage of producing a much greater variability in the yield because of the conseguent reduction in the number of year classes making a substantial contribution to the yield. The analysis of the harp seal population showed that this population is being over-harvested, and that if the size of the pup harvest is not reduced the entire pup production would be harvested by 1980. If the harvest rates are substantially reduced a sustained harvest could be taken, the best estimate of a sustained kill of pups only was 172,000. Because the estimates of the parameters are not very precise an analysis of the sensitivity of the results to changes in the parameters was made, and this showed if the estimates are not very accurate' considerable errors could be made in the predictions of the model. This analysis was used to compare several possible observations that could be used to check the effect of a reduced harvest on the population, and of these the catch curves of the younger age groups offered the best compromise between sensitivity to changes in population size and ease of measurement.

description: While climate change was largely tackled by government policies in the past, central banks are increasingly grappling with the risks climate change poses. They are evaluating their operational policies to reflect these risks and the transition to a net-zero economy. This paper explores the trade-offs and considerations central banks face.

description: We describe in detail a counterexample to the topological classification of free fermion systems. We deal with a one dimensional chain of Majorana fermions with an unusual T symmetry. The topological invariant for the free fermion classification is an integer, but with the introduction of interactions it becomes well defined only modulo 8. We illustrate this in the microscopic model of the Majorana chain by constructing an explicit path between two distinct free phases whose topological invariants are equal modulo 8, along which the system remains gapped. The path goes through a strongly interacting region. We also find the field theory interpretation of this phenomenon. There is a second order phase transition between the two phases in the free theory which can be avoided by going through the strongly interacting region. We show that this transition is in the 2D Ising universality class, where a first order phase transition line, terminating at a second order transition, can be avoided by going through the analogue of a high temperature paramagnetic phase. In fact, we construct the full phase diagram of the system as a function of the thermal operator (i.e. the mass term that tunes between the two phases in the free theory) and two quartic operators, obtaining a first order Peierls transition region, a second order transition region, and a region with no transition.

Modelling the sensitivity of dense shelf water formation in the Mertz Glacier region, East Antarctica
Creators: name: Cougnon, EA
Publisher: name: University Of Tasmania
Year: 2023

description: Given the importance of the overturning circulation to global climate, there is a need to improve our understanding of Antarctic Bottom Water (AABW) formation and its sensitivity to change. The offshore properties of AABW are changing. Within the Australian-Antarctic basin AABW has freshened and decreased in volume by about 50% over the last few decades. Understanding what is driving these changes requires focusing on the key formation region along the Adelie and George V Land (AGVL) coast. Here, the intense production of sea ice in the Mertz Glacier Polynya system drives Dense Shelf Water (DSW) formation, the precursor to AABW. This thesis uses a version of the Regional Ocean Modeling System (ROMS) that has been adapted for ocean/ice-shelf interactions to explore the sensitivity of DSW formation to surface heat and salt fluxes and ice shelf basal melting. Interannual variability in surface heat and salt fluxes drives DSW export and ice shelf basal melting variability in the AGVL region. DSW export decreases by 86% during a sustained period (2000-2002) of weak polynya activity (sea ice production) before recovering during a sustained period of stronger polynya activity (2003-2005). Basal melting of the Mertz Glacier Tongue (MGT) doubles under weak polynya activity because more warm water reaches the base of the ice shelf. Idealised simulations highlight the importance of the air/sea fluxes on DSW formation and ice shelf basal melting. A mean to strong air/sea forcing drives convection of dense water to sink at the sea floor and drives melt near the deep grounding line. Weaker air/sea forcing limits the depth of the convection and allows greater intrusions of warm modified Circumpolar Deep Water within the ice shelf cavity and increases basal melting. The resultant input of glacial meltwater produces a buoyant plume that stratifies the water column. Two simulations are run to investigate the impact of the calving of the MGT in 2010. Weaker polynya activity after calving results in an 89% increase in area averaged ice shelf basal melting and an 80% decrease of DSW export from the Adelie depression. Most importantly a distinct warming of the exported DSW leads to a decrease in AABW production downstream. This thesis demonstrates the sensitivity of Antarctic ocean-cryosphere interactions to interannual variability and episodic changes to the local icescape (ice shelves, icebergs and sea ice), finding that ice shelf basal melting and DSW formation in the AGVL region is dramatically impacted by the MGT calving.
Vacancy-induced magnetism in SnO$_{2}$: A density functional study

description: We study the magnetic and electronic properties of defects in SnO$_{2}$ using pseudopotential and all electron methods. Our calculations show that bulk SnO$_{2}$ is non-magnetic, but it shows magnetism with a magnetic moment around 4.00 $μ_{B}$ due to Sn vacancy (V$_\mathrm{Sn}$). The magnetic moment comes mainly from O atoms surrounding V$_\mathrm{Sn}$ and Sn atoms, which couple antiferromagnetically with the O atoms in the presence of V$_\mathrm{Sn}$. The coupling between different Sn vacancies is also studied and we find that these defects not only couple ferromagnetically but also antiferromagnetically and ferrimagnetically. Our calculations demonstrate that the experimentally observed giant magnetic moment of transition metal doped SnO$_{2}$ can be attributed to V$_\mathrm{Sn}$.

Bringing students to their profession and the profession to students through competency standards
Creators: name: Nash, RE
Publisher: name: University Of Tasmania

description: New medicines come to market daily and health services continually evolve, consequently knowledge in the health disciplines acquired at university quickly outdates. The public demands that health practitioners maintain their competence to practice. Amongst other purposes, a profession's competency standards are an essential guide for an individual practitioner's life-long learning. The purpose of this research was to explore whether the National Competency Standards Framework for Pharmacists in Australia (NCS) informed pharmacy education and then to trial an approach in one Australian pharmacy program which directed students specifically to the competency standards. The research aimed to determine familiarity with the NCS amongst the profession, educators and students; to compare how competency standards inform curriculum design in Australia with how they are used internationally; and to establish the current barriers and enablers to the use of NCS in pharmacy education in Australia. These findings inspired the design of an educational intervention entitled the 'Traffic Light Report', trialled at one Australian university with undergraduate pharmacy students. The Traffic Light Report (TLR) was designed to 'bring students to their profession and the profession to students through Competency Standards.'

description: Modern mobile phones are increasingly being used for more services that require modern security mechanisms such as the public key cryptosystem RSA. It is, however, well known that public key cryptography demands considerable computing resources and that RSA encryption is much faster than RSA decryption. It is consequently an interesting question if RSA as a whole can be executed efficiently on modern mobile phones. In this paper, we explore the efficiency on modern mobile phones of variants of the RSA cryptosystem, covering CRT, MultiPrime RSA, MultiPower RSA, Rebalanced RSA and R Prime RSA by comparing the encryption and decryption time using a simple Java implementation and a typical RSA setup.

description: We study spin and charge currents pumped by precessing magnetization of a single ferromagnetic layer within F|I|N or F|I|F (F-ferromagnet; I-insulator; N-normal-metal) multilayers of nanoscale thickness attached to two normal metal electrodes with no applied bias voltage between them. Both simple one-dimensional model, consisting of a single precessing spin and a potential barrier as the "sample," and realistic three-dimensional devices are investigated. In the rotating reference frame, where the magnetization appears to be static, these junctions are mapped onto a four-terminal dc circuit whose effectively half-metallic ferromagnetic electrodes are biased by the frequency $\hbar ω/e$ of microwave radiation driving magnetization precession at the ferromagnetic resonance (FMR) conditions. We show that pumped spin current in F|I|F junctions, diminished behind the tunnel barrier and increased in the opposite direction, is filtered into charge current by the second $F$ layer to generate dc pumping voltage of the order of $\sim 1$ $μ$V (at FMR frequency $\sim 10$ GHz) in an open circuit. In F|I|N devices, several orders of magnitude smaller charge current and the corresponding dc voltage appear concomitantly with the pumped spin current due to barrier induced asymmetry in the transmission coefficients connecting the four electrodes in the rotating frame picture of pumping.

The more things change, the more they stay the same : representations of whiteness in Australian history narratives 1950-2010
Creators: name: Moore, Robyn
Publisher: name: University Of Tasmania

description: This thesis examines representations of whiteness and otherness in Australian secondary school social science textbooks from 1950-2010. Using textbooks as records of dominant narratives, I identify continuities and changes to the visibility and substantive nature of whiteness and otherness over this period. In particular, I analyse the discursive shifts which facilitated the transition in whiteness from a symbol of overt superiority to one of normality, characterised by 'unknowing'. Utilising a theoretical framework comprising critical whiteness studies and ignorance theory, I employ content and critical discourse analysis to investigate how dominant discourses produce and maintain categories of belonging and exclusion. I focus on the role of ignorance in the perpetuation of these categories despite substantial legislative and social change during the research period, signified by the transition from the White Australia era to multiculturalism. Textbooks reflect the shift in the broader polity over the research period: White dominance persists by becoming unmarked. Although representations of whiteness and otherness in textbooks become less visible, the constructs themselves endure. Similarly, Whites' position at the centre of the nation and non-Whites' at the margins persists despite changes to the substantive nature of these constructs: less overt assertions of White superiority and constructions of others as different rather than deficient. Even the increased representation of non-Whites fails to unsettle this dynamic; by siloing this content, dominant whiteness is not disrupted. Continuities despite apparent change are enabled by White ignorance. The absence of overt assertions of White superiority and non-White deficiency in the multicultural era maintains White racial dominance while engendering White ignorance by rendering constructions of whiteness and otherness less explicit. In conjunction with the reduced visibility of these constructs, these less overt formulations shield the racialised nature of the polity from critique, ensuring that White ignorance is reproduced rather than interrupted. These discursive strategies (re)construct Australianness as White, irrespective of the racial diversity of the contemporary Australian population.
