description: This study performs a comparison of two model calibration/validation approaches and their influence on future hydrological projections under climate change by employing two climate scenarios (RCP2.6 and 8.5) projected by four global climate models. Two hydrological models (HMs), snowmelt runoff model + glaciers and variable infiltration capacity model coupled with a glacier model, were used to simulate streamflow in the highly snow and glacier melt–driven Upper Indus Basin. In the first (conventional) calibration approach, the models were calibrated only at the basin outlet, while in the second (enhanced) approach intermediate gauges, different climate conditions and glacier mass balance were considered. Using the conventional and enhanced calibration approaches, the monthly Nash-Sutcliffe Efficiency (NSE) for both HMs ranged from 0.71 to 0.93 and 0.79 to 0.90 in the calibration, while 0.57–0.92 and 0.54–0.83 in the validation periods, respectively. For the future impact assessment, comparison of differences based on the two calibration/validation methods at the annual scale (i.e. 2011–2099) shows small to moderate differences of up to 10%, whereas differences at the monthly scale reached up to 19% in the cold months (i.e. October–March) for the far future period. Comparison of sources of uncertainty using analysis of variance showed that the contribution of HM parameter uncertainty to the overall uncertainty is becoming very small by the end of the century using the enhanced approach. This indicates that enhanced approach could potentially help to reduce uncertainties in the hydrological projections when compared to the conventional calibration approach. © 2020, The Author(s).
Neutrino mass generation in the SO(4) model

description: Generation of neutrino mass in SO(4) model is proposed here. The algebraic structure of SO(4) is same as to that of $SU(2)_{L}\times SU(2)_{R}$. It is shown that the spontaneous symmetry breaking results three massive as well as three massless gauge bosons. The standard model theory according to which there exist three massive gauge bosons and a massless one is emerged from this model. In the framework of $SU(2)_{L}\times SU(2)_{R}$ a small Dirac neutrino mass is derived. It is also shown that such mass term may vanish with a special choice. The Majorana mass term is not considered here and thus in this model the neutrino mass does not follow seesaw structure.

An investigation of Gordon's common stock valuation model
Creators: name: Smith, Patrick John
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this study was to determine whether a model based upon the dividend formulation of Myron J. Gordon provides an adequate explanation of the variation in common stock prices. In particular, the hypothesis tested is that investors mainly consider dividends, the rate of growth in dividends and the risk characteristics of the firms in valuing shares of common stock. The model was tested by using multiple regression analysis on a cross-section of U.S. companies in the machinery industry in each of the years 1956 to 1965. Alternative measures or proxies for "normalized" earnings, growth, business risk and financial risk were used in testing the model. Empirical results supported the proposition that Gordon's model provides an adequate explanation of the variation in stock prices. On average, between 76% and 81% of the total variation was explained by the model over the ten-year period. The R² values for each year ranged between .68 and .90. The coefficients of the dividend, growth and size variables were significant at the 5% level or better in almost all the years tested and except for growth in two years, these coefficients had the sign indicated by the theory. Business risk and financial risk performed poorly as explanatory variables. The coefficients for both variables were not statistically significant at the 5% level in most years and the business risk coefficient frequently did not have the expected sign.

description: Experiments with gold-gold collisions at RHIC have revealed (i) stronger suppression of charmonium production at forward rapidity than at midrapidity and (ii) the similarity between the suppression degrees at RHIC and SPS energies. To describe these findings we employ the model that includes nuclear shadowing effects, calculated within the Glauber-Gribov theory, rapidity-dependent absorptive mechanism, caused by energy-momentum conservation, and dissociation and recombination of the charmonium due to interaction with co-moving matter. The free parameters of the model are tuned and fixed by comparison with experimental data at lower energies. A good agreement with the RHIC results concerning the rapidity and centrality distributions is obtained for both heavy Au+Au and light Cu+Cu colliding system. For pA and A+A collisions at LHC the model predicts stronger suppression of the charmonium and bottomonium yields in stark contrast to thermal model predictions.

description: Neutrino oscillations are examined under the broad requirements of Poincaré-invariant scattering theory in an S-matrix formulation. This approach can be consistently applied to theories with either field or particle degrees of freedom. The goal of this paper is to use this general framework to identify all of the unique physical properties of this problem that lead to a simple oscillation formula. We discuss what is in principle observable, and how many factors that are important in principle end up being negligible in practice.

description: Semi-arid regions are known for erratic precipitation patterns with significant effects on the hydrological cycle and water resources availability. High temporal and spatial variation in precipitation causes large variability in runoff over short durations. Due to low soil water storage capacity, base flow is often missing and rivers fall dry for long periods. Because of its climatic characteristics, the semi-arid north-eastern region of Brazil is prone to droughts. To counter these, reservoirs were built to ensure water supply during dry months. This paper describes problems and solutions when calibrating and validating the eco-hydrological model SWIM for semi-arid regions on the example of the Pajeú watershed in north-eastern Brazil. The model was calibrated to river discharge data before the year 1983, with no or little effects of water management, applying a simple and an enhanced approach. Uncertainties result mainly from the meteorological data and observed river discharges. After model calibration water management was included in the simulations. Observed and simulated reservoir volumes and river discharges are compared. The calibrated and validated models were used to simulate the impacts of climate change on hydrological processes and water resources management using data of two representative concentration pathways (RCP) and five earth system models (ESM). The differences in changes in natural and managed mean discharges are negligible (< 5%) under RCP8.5 but notable (> 5%) under RCP2.6 for the ESM ensemble mean. In semi-arid catchments, the enhanced approach should be preferred, because in addition to discharge, a second variable, here evapotranspiration, is considered for model validation. © 2020, The Author(s).

description: In this paper, results of 2.5-dimensional magnetohydrodynamical simulations are reported for the magnetic reconnection of non-perfectly antiparallel magnetic fields. The magnetic field has a component perpendicular to the computational plane, that is, guide field. The angle theta between magnetic field lines in two half regions is a key parameter in our simulations whereas the initial distribution of the plasma is assumed to be simple; density and pressure are uniform except for the current sheet region. Alfven waves are generated at the reconnection point and propagate along the reconnected field line. The energy fluxes of the Alfven waves and magneto-acoustic waves (slow mode and fast mode) generated by the magnetic reconnection are measured. Each flux shows the similar time evolution independent of theta. The percentage of the energies (time integral of energy fluxes) carried by the Alfven waves and magneto-acoustic waves to the released magnetic energy are calculated. The Alfven waves carry 38.9%, 36.0%, and 29.5% of the released magnetic energy at the maximum (theta=80^\circ) in the case of beta=0.1, 1, and 20 respectively, where beta is the plasma beta (the ratio of gas pressure to magnetic pressure). The magneto-acoustic waves carry 16.2% (theta=70^\circ), 25.9% (theta=60^\circ), and 75.0% (theta=180^\circ) of the energy at the maximum. Implications of these results for solar coronal heating and acceleration of high-speed solar wind are discussed.

description: Bioenergy is expected to play an important role in the achievement of stringent climate-change mitigation targets requiring the application of negative emissions technology. Using a multi-model framework, we assess the effects of high bioenergy demand on global food production, food security, and competition for agricultural land. Various scenarios simulate global bioenergy demands of 100, 200, 300, and 400 exajoules (EJ) by 2100, with and without a carbon price. Six global energy-economy-agriculture models contribute to this study, with different methodologies and technologies used for bioenergy supply and greenhouse-gas mitigation options for agriculture. We find that the large-scale use of bioenergy, if not implemented properly, would raise food prices and increase the number of people at risk of hunger in many areas of the world. For example, an increase in global bioenergy demand from 200 to 300 EJ causes a − 11% to + 40% change in food crop prices and decreases food consumption from − 45 to − 2 kcal person−1 day−1, leading to an additional 0 to 25 million people at risk of hunger compared with the case of no bioenergy demand (90th percentile range across models). This risk does not rule out the intensive use of bioenergy but shows the importance of its careful implementation, potentially including regulations that protect cropland for food production or for the use of bioenergy feedstock on land that is not competitive with food production. © 2020, The Author(s).
Sexual health issues in adolescents : an examination of the discourses of sexuality within health education
Creators: name: Winckle, J
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis, 'Sexual health issues in adolescents: an examination of the discourses of sexuality within health education', is a feminist poststructural and critical ethnographic investigation of the production of knowledge and gendered subjectivities within a single Tasmanian secondary co-educational government school. The main focus of the research is on the ways in which power operates through dominant teaching practices to constitute particular versions of sexuality as the truth, and to what effect (Foucault 1980). The research focuses upon teacher and student dominant discursive constructions of knowledge regarding sex, sexuality and sexual decision-making and its impact upon students' production of gendered subjectivity and the sex education program's potential for addressing issues of sexual violence, homophobia and sexual health. The thesis argues that current pedagogies within curriculum-based sex education classes reproduce binary versions of gender, which are inequitable and significantly limiting in terms of transforming homophobic, sexist and discriminatory attitudes. The methodology for this thesis combines the principles of constructivist grounded theory (Charmaz 2000, 2006) and Foucauldian discourse analysis (Carabine 2001) to develop a framework for data collection and analysis which acknowledges how discourses and social practices construct both a representation of experience and a positioning of individuals as gendered subjects (Hiller 1998). In conclusion, this thesis offers recommendations for an alternative model of curriculum-based sex education informed by feminist poststructuralist theory and based upon a critical pedagogical approach that focuses on the concept of sexual ethics. These recommendations are informed by the knowledge that critical pedagogies can become catalysts for change in the way sex education is currently perceived, by enabling the production of new knowledges, new discourses and new, more equitable pedagogical practices (Kamler 2001).
The development and investigation of a model for introducing jazz education to secondary school ensembles
Creators: name: Rettke, P
Publisher: name: University Of Tasmania
Year: 2023

description: This study is aimed at producing a jazz teaching model for the short-term training of students with little or no jazz experience. By using a mainly experiential approach over a set time frame and limiting the instruction to certain elements of jazz interpretation, it aims to present a reasonable introduction to small jazz ensemble performance in the Australian secondary school sector (grade 7-12). The research grows out of more than two decades experience introducing jazz performance to secondary school students where a well-defined pedagogical problem has been identified as a result of the lack of instructional methods for teachers wishing to instruct secondary school students in small jazz ensemble performance. This tuition model aims to fulfil certain quantifiable criteria over a set period of time. The efficacy of the model is assessed by the success of attaining basic parameters and qualified by the performance outcome at the end of the model implementation period. The project has been structured to establish that the model for instruction, proposed as a solution for a research (teaching-based) problem, is successful. In 2003 eighteen Year 11 Victorian Certificate of Education music students, comprising two classes, were filmed at two-week intervals, over an eight-week period, while being instructed with the model. At the end of the eight-week period they were surveyed to gauge their theoretical and experiential development. The candidate continued to develop the model by adding extra individual instrumental techniques, a list of selected recordings, timetabling for all classes and recommendations for aural training techniques. As a comparison two more Year 11 Victorian Certificate of Education classes, comprising fourteen students, were again filmed at two-week intervals in 2006. Again they were surveyed at the end of the eight-week period to gauge both their development and their reaction to the classroom model. The results of the surveys from both years are examined along with the visual evidence of the students' performances over the eight week period of instruction that are included on DVDs with this thesis. On this evidence a case is made for the efficacy of the proposed model of instruction.

description: Bushrangers have a powerful grip on the Australian psyche. Ned Kelly is celebrated as Australia's most popular folk hero. Bushranger Captain Thunderbolt has been immortalised in his home state of New South Wales, with a major highway named in his honour. For the town of Uralla in the New England District, the Thunderbolt legend looms large. He is a major tourist draw card for the region. The legend of Thunderbolt embodies a larger telling of a collective struggle against a system of injustice and oppression. A closer examination of events reveals that Thunderbolt's Aboriginal wife, Mary Ann, was crucial to his survival. Yet she has been erased from the legend. Many of our folk heroes could not have survived without the support of Aboriginal Australians. However the mateship ethos continues to exclude both Aboriginal people and women. In documenting the life of Worimi woman Mary Ann and her partnership with Thunderbolt, the rhetoric of mateship is challenged. Reciprocal relationships that developed between Aboriginal and settler Australians will be investigated. It is important to consider the range of relationships that emerged on the frontier and the bearing that geography played in such encounters. By adopting a place-centred approach one is able to closely examine the complexity of race relations that existed in colonial times. The violent encounters that occurred on the frontier between Aboriginal and settler Australians are well documented. However not all relationships were based on exploitation and violence. The union between Mary Ann's Aboriginal mother and English convict father is celebrated by the Worimi today. Mixed marriage continues to be recognised as a central part of contemporary Worimi culture.

Spatial and temporal variation in the health of an endemic Tasmanian tree, Eucalyptus gunnii Hook.f.
Creators: name: Calder, J
Publisher: name: University Of Tasmania
Year: 2023

description: Eucalyptus gunnii Hook.f. is a tree endemic to the subalpine regions of Tasmania. A subspecies, E. gunnii spp. divaricata (McAulay & Brett) B.M. Potts, has recently been listed as endangered, due to extensive dieback over the last few decades. It has been suggested that the dieback may be in part due to increased intensity and frequency of droughts brought about by climate change. Examination of weather records indicated that a prolonged dry period has occurred across in much of the species' range. Mean annual temperatures have also risen. The timing of dieback, observed through a time series of aerial photographs, coincided with the timing of the worst droughts in some regions. However, field surveys of the health of E. gunnii across its range indicated a stronger negative relationship between livestock grazing and tree health than between rainfall and tree health. This may have been partly due to the long term suppression of regeneration in these populations, and therefore the predominantly old age of many of the trees, and their lower resilience to stress. Possum defoliation was also implicated as a major agent of decline. Furthermore, the possibility was raised that herbivorous insects are having a greater impact at higher altitudes than previously, which could be due to warmer winter temperatures. Although it was difficult to unravel the effects of climate and land management changes, the results suggested that we may already be seeing the impacts of climate change in Tasmania, especially in those environments which have been most heavily modified by land use.
Models of Yukawa interaction in the two Higgs doublet model, and their collider phenomenology

description: Possible models of Yukawa interaction are discussed in the two Higgs doublet model (THDM) under the discrete symmetry imposed to avoid the flavor changing neutral current at the leading order. It is known that there are four types of such models corresponding to the possible different assignment of charges for the discrete symmetry on quarks and leptons. We first examine decay properties of Higgs bosons in each type of the models, and summarize constraints on the models from current experimental data. We then shed light on the differences among these models in collider phenomenology. In particular, we mainly discuss so-called the Type-II THDM and the Type-X THDM. The Type-II THDM corresponds to the model with the same Yukawa interaction as the minimal supersymmetric standard model (MSSM). On the other hand, in the Type-X THDM, additional Higgs bosons can predominantly decay into leptons. This scenario may be interesting because of the motivation for a light charged Higgs boson scenario such as in the TeV scale model of neutrino, dark matter and baryogenesis. We study how we can distinguish the Type-X THDM from the MSSM at the Large Hadron Collider and the International Linear Collider.

Place matters: Finding deep ecology within towns and cities
Creators: name: Booth, Kate
Publisher: name: University Of Tasmania
Year: 2023

description: Deep ecology is a branch of ecophilosophy with a focus on wilderness philosophy and that appears to hold little relevance within an urbanising world. Yet deep ecology's holistic account claims that everything is interconnected ‚Äö- not just those entities definable as wild or natural ‚Äö- but everything, including all those things that deep ecology has remained wary of and aloof from ‚Äö- machines, exotic species, department stores, concrete and tar. This dissertation is an exploration of deep ecological metaphysics, specifically that of transpersonal ecology, within towns and cities. It considers how engagement within towns and cities may influence or change the metaphysical premise of deep ecology, and looks at how revisiting the holism therein may alter how we understand world and self, particularly with reference to towns and cities. The particularities of the place within which this research is grounded are described. The suburb of Risdon Vale and the author's sense of place are introduced in terms of locality and locale, and with reference to two streams within place discourse ‚Äö- memory and place, and geographer Doreen Massey's 'global sense of the local, a global sense of place'. Three phenomenological encounters are narrated and discussed. The first encounter, entitled 'gum-tree-man', initiates a discussion of Norwegian philosopher Arne Naess's gestalt ontology. The second, 'touch me, this tree', takes a fresh look at the concepts of wildness and wilderness from the perspective of gestalt ontology, and the third, 'capillary shawl', moves to consider self and the notion of consciousness as emergent from encounter between the author and her washing machine. A notion of place emerges that forms the basis for the development of a concept termed 'the locality of place'. The locality of place and symbiosis are offered as alternatives to transpersonal ecology and Self-realisation. Accusations that deep ecology harbours fascist tendencies are addressed in light of the emerging ideas. Deep ecology emerges as a poignant ontological perspective holding relevance and significance for considerations of self, place and world. Finally, a re-conception of towns and cities, including of our selves, technologies and exotic species is explored. The notions of relational familiarity and unfamiliarity are offered as means of understanding current trends in relational enmeshment, and the increasingly problematic nature of these trends is discussed. An embodied turn towards familiarising ourselves within our own relational enmeshments is offered as a means of increasing our understanding of ourselves, world and where we are at within towns and cities.

The invariant-comb approach and its relation to the balancedness of multipartite entangled states
Creators: name: Osterloh, A.
name: Siewert, J.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The invariant-comb approach is a method to construct entanglement measures for multipartite systems of qubits. The essential step is the construction of an antilinear operator that we call {\em comb} in reference to the {\em hairy-ball theorem}. An appealing feature of this approach is that for qubits (or spins 1/2) the combs are automatically invariant under $SL(2,\CC)$, which implies that the obtained invariants are entanglement monotones by construction. By asking which property of a state determines whether or not it is detected by a polynomial $SL(2,\CC)$ invariant we find that it is the presence of a {\em balanced part} that persists under local unitary transformations. We present a detailed analysis for the maximally entangled states detected by such polynomial invariants, which leads to the concept of {\em irreducibly balanced} states. The latter indicates a tight connection with SLOCC classifications of qubit entanglement. \\ Combs may also help to define measures for multipartite entanglement of higher-dimensional subsystems. However, for higher spins there are many independent combs such that it is non-trivial to find an invariant one. By restricting the allowed local operations to rotations of the coordinate system (i.e. again to the $SL(2,\CC)$) we manage to define a unique extension of the concurrence to general half-integer spin with an analytic convex-roof expression for mixed states.

Hypervigilance and Disengagement Difficulties in Spider Fear: An Event-Related Potential Study
Creators: name: Johnstone, ASV
Publisher: name: University Of Tasmania
Year: 2023

description: Hypervigilance to threat and difficulty disengaging attention from threat are features of attentional biases in anxiety. However, research has not investigated both of these biases in specific fear. This study investigated attentional biases in 13 females with high spider fear and 10 low-fear controls aged between 18-30 years. Participants completed a spatial cueing task with spider and cow images as cues appearing in either the same location (valid) or in the opposite location (invalid) as the following target requiring a button-press response. The hypotheses that high-fear participants would display hypervigilance through shorter reaction times and greater P1 amplitude to targets with valid-spider cues, and disengagement difficulties through greater reaction times and decreased P1 amplitude to targets with invalid-spider cues were not supported. Greater reaction times for all cues in high-fear participants were observed. High fear participants displayed similar P1 amplitude to all targets regardless of cue whereas low-fear controls displayed increased P1 amplitude to spider-cued targets. Findings were interpreted as two processes in high-fear participants; general hypervigilance, suggested by generally increased P1 amplitude, followed by interference in reactions to targets. The P1 amplitude displayed in the low-fear group may suggest an evolutionary mechanism. These results may suggest a focus on general hypervigilance in spider-fear treatment.

description: We reiterate, in more details, our previous proposal of using quasi-particle interference to determine the pairing form factor in iron-based superconductors. We also present our functional renormalization group(FRG) results on LaFePO and Fe(Se,Te) superconductors. In particular we found that the leading pairing channel in LaFePO is nodal s$_{\pm}$, with nodes on electron Fermi surfaces. For Fe(Se,Te) system we found fully gapped s$_{\pm}$ pairing, with substantial gap anisotropy on electron Fermi surfaces, and large gap is concentrated in regions with dominant $xy$ orbital character. We further fit the form factor obtained by FRG to real space orbital basis pairing picture, which shows more clearly the differences between different iron-based superconductors.

description: Today’s standard medium voltage converters are operated at low switching frequencies and contain bulky line filters. One concept to change this is the Quasi-Two-Level operation of multilevel converters with fast switching semiconductors to minimize passive components. This paper presents the hardware of a full-scale medium voltage SiC-based flying capacitor converter for quasi-two-level operation with up to 10kV DC voltage and 150A line current. This hardware enables studies on the influence of components, modulation principles and control algorithms on the needed filters and the operation of the converter.
Our place, or mine? : sense of place, social impact assessment and coal mining in Gloucester, NSW
Creators: name: Jordan, W
Publisher: name: University Of Tasmania
Year: 2023

description: This study examines the impact of coal mining and coal seam methane (CSM) extraction on the 'sense of place' of the people of the Gloucester Shire, New South Wales. The findings derived from Gloucester inform an analysis of the potential for recognising loss of 'place' as a social impact within social impact assessment (SIA). This potential was considered within the geographic context of the Hunter Valley, Gunnedah Basin, and Gloucester Valley, which constitute contiguous and related regions subject to coal development. Previous research in similar contexts indicated that a felt loss of place was likely. A methodology was adopted that combined survey-based quantitative analysis, key informant interviews, and extensive consideration of the literature of place and SIA. Results indicate that loss of place is being felt strongly by the Gloucester community, although considerable divergence exists in both felt loss of place and support for coal-related development. Widespread dissatisfaction with the prevailing levels of community input into development processes also emerged as a significant issue with particular ramifications for the maintenance of place. While a substantial loss of place was in evidence in Gloucester, the recognition of this loss as a social impact is suggested as being hampered by mensuration difficulties, the diversity of 'place attachments', and the nature of impact assessment decision-making. The establishment of placeconscious, participatory SIA processes is suggested as an alternative mechanism for mitigating place loss in the coal mining areas of the Hunter, Gunnedah, and Gloucester regions.

Visual context and affect in diagram interpretation

description: Graphical displays of scientific information (graphs, plots, diagrams etc.) play a vital role in the communication of science, both among researchers and more broadly with non-scientists. Research into the interpretation of science graphics tends to focus on comprehension and information transfer. The findings of such research support a general trend toward reductionist diagram designs, the reasoning being that a focused design, unencumbered by extraneous details, allows the viewer to concentrate on the target information without unwanted distractions. There has been relatively little attention paid to emotional or attitudinal responses to diagrams, despite the fact that this may be significant for communicators aiming to stimulate interest, influence attitudes, or motivate action. Furthermore, contextualisation of science instruction is thought to be important for motivation, interest, and academic performance, however the general trend in diagram design—to remove the extraneous—leads to a removal of context from diagrams. The research reported in this thesis takes the specific case of biological life cycle diagrams to explore the impact of visual context on affect. The thesis consists of two qualitative focus group studies to explore viewer responses to context in diagrams, and a large-scale quantitative between-groups comparison survey to test findings from the focus groups and examine the impacts of context in more detail. Due to the inherent complexity of diagram interpretation and the exploratory nature of the project, findings were highly nuanced. However there were clear signs that context was associated with emotional and attitudinal aspects of diagram interpretation. Specifically, context appeared to encourage an elevated sense of empathy with, and concern for the animal portrayed in diagrams, along with a greater sense of relevanceof the information. A number of individual participant characteristics that influenced response to context were also identified. Implications of the specific findings of this research for the communication of scientific topics are discussed, along with broader implications for research into diagram interpretation.
A general framework for multiple scattering of polarized waves including anisotropies and Berry phase

Subjects: subject: Other Condensed Matter (cond-mat.other)

description: We develop a framework for the multiple scattering of a polarized wave. We consider particles with spin propagating in a medium filled with scatterers. We write the amplitudes of each spin eigenstate in a local, mobile frame. One of the axes is in the direction of propagation of the particle. We use this representation to define a directional Green's operator of the homogeneous medium and also to write the spin-dependent scattering amplitudes. We show that this representation reveals a Berry phase. We establish a generalized Green-Dyson equation for the multiple scattering problem in this framework. We show that the generalized Green-Dyson equation can be solved by linear algebra if one uses a representation of the rotations based on Wigner D-matrices. The properties of light scattering are retrieved if we use spin 1 particles. Our theory allows to take into account several kinds of anisotropies like circular or linear dichroism and birefringence, Faraday effects andMie scattering within the same formalism. Several anisotropies can be present at the same time.

description: We consider the cluster algebra associated to the $Q$-system for $A_r$ as a tool for relating $Q$-system solutions to all possible sets of initial data. We show that the conserved quantities of the $Q$-system are partition functions for hard particles on particular target graphs with weights, which are determined by the choice of initial data. This allows us to interpret the simplest solutions of the Q-system as generating functions for Viennot's heaps on these target graphs, and equivalently as generating functions of weighted paths on suitable dual target graphs. The generating functions take the form of finite continued fractions. In this setting, the cluster mutations correspond to local rearrangements of the fractions which leave their final value unchanged. Finally, the general solutions of the $Q$-system are interpreted as partition functions for strongly non-intersecting families of lattice paths on target lattices. This expresses all cluster variables as manifestly positive Laurent polynomials of any initial data, thus proving the cluster positivity conjecture for the $A_r$ $Q$-system. We also give an alternative formulation in terms of domino tilings of deformed Aztec diamonds with defects.

Analysis of freight transportation in the Yukon economy
Creators: name: Freybe, Henning Carl Albert
Publisher: name: University of British Columbia

description: Transportation has always been of vital importance in the Yukon because of the small population, the harsh climate, and the remoteness from large markets. It has imported almost all of its industrial and consumer goods, supported by the export of a limited tonnage of high value mineral concentrates. Little growth has occurred in the past fifteen years in the value of mineral production, as it has remained fairly constantly at about $14 million. At present, though, the Yukon is in a stage of transition as many ore bodies are being brought into production. The effect on the Yukon economy will be substantial, as one estimate sees the dollar value of production increasing more than three-fold by 1975. The objective of this thesis is to determine the impact of this economic change on the total transport system. It is thus necessary to establish a measurement of the present level of freight services (the year chosen is 1964) and to establish a forecast of freight services for 1975. The measurement and forecast are then used to determine in what way the economic change may influence transport rates and services. The main sources of information for this paper were the various transportation and mining companies that are engaged in Yukon activities. Considerable use was made of the 1966 Stanford Research Institute study that concerned itself with the economics of paving the Alaska Highway. While many other sources were also consulted, they were generally of lesser importance. The growth rate of goods going north into the Yukon is forecast to be a moderate 5% per annum. The growth in the amount of ore concentrates going out of the Yukon should be considerably larger. For every ton moving north into the Yukon in 1964, 1.5 tons of freight moved out of the area, while by 1975 the ratio should increase to 6.5 tons for every northbound ton. As the present and planned mining developments are principally in the area north and northeast of Whitehorse where the White Pass and Yukon Route has the competitive advantage, most of the direct increase in freight traffic should benefit the White Pass and Yukon Route. Other transport companies should benefit also, but more due to indirect effects of the mining developments on freight traffic. The increase in the level of freight should make possible a higher utilization of present facilities and lower average costs. It appears that especially for the White Pass and Yukon Route the potential for reductions in freight rates should increase.
