Australia's organic trilemma: Public versus private organic food standardisation
Creators: name: Hall, SB
Publisher: name: University Of Tasmania
Year: 2023

description: The Australian organic food industry has reached a political impasse. Despite being one of the fastest growing sectors of the food economy, the organic industry in Australia remains largely self-governed. There is no specific legislation for domestic organic food standardisation and labelling at the state or federal level as there is in the USA and the EU. The situation has engendered deep division within the sector. While there is recognition among most organic industry actors about a need for regulatory reform and greater engagement with government, there is disagreement over the appropriate nature and extent of government intervention. Some sectoral actors seek government regulation to facilitate the maturation and expansion of the organic industry and to protect consumers and producers from labelling fraud. Others fear that government regulation may undermine the values and traditions of the Australian organic agriculture movement. Drawing upon the social theories of Jurgen Habermas, Niklas Luhmann and Gunther Teubner, the thesis argues the Australian situation represents an example of a regulatory trilemma. Inappropriate government regulation may: (1) be ignored and thus redundant; or (2) it may destroy the inherent structure and normative dynamics of Australia's organic food system; or (3) be counteracted by positive systemic resistance from the organic sector. The thesis finds a reflexive approach provides a sound basis for establishing the limits of government regulation of the organic sector and represents an effective response to the trilemma.

Effect of hot-water soluble Thuja Plicata heartwood extractives on the growth of Thuja and non-Thuja isolates of Poria Weirii.
Creators: name: Morrison, Duncan John
Publisher: name: University of British Columbia
Year: 2011

description: Poria weirii Murr. isolates cultured from various hosts may be divided into two groups on the basis of their ability to parasitize Thuja plicata Donn and to grow on media containing water-soluble T. plicata heartwood extractives. The role of these extractives in determining whether a Poria weirii isolate can parasitize Thuja plicata was examined. Measurement of linear growth along wood micro-sections confirmed that substances inhibitory to one isolate group are hot-water soluble T. plicata heartwood extractives. The tolerance of isolates from T. plicata (Thuja) and Pseudotsuga menziesii (Mirb.) Franco (non-Thuja) to a hot-water extract of Thuja plicata heartwood and its hexane soluble (principally thujaplicins) and insoluble (thujaplicin-free) fractions was studied in detail. Dry weight of mycelium produced in liquid glucose-asparagine medium was measured. Thuja isolates were more tolerant than non-Thuja of the hot-water extract and its fractions; thujaplicins caused the greatest response differences. Thuja isolates showed greater stimulation than non-Thuja at subinhibitory thujaplicin concentrations. Higher thujaplicin concentrations were required to produce fungistatic and -toxic conditions in Thuja isolates than in non-Thuja. There were highly significant differences between isolate groups in response to 7.5 ppm thujaplicin. Tolerance was not related to date of isolation or geographical location. With sufficient inoculum potential, a non-Thuja isolate may overcome T. plicata heartwood toxicity. The resulting infection is usually localized. Unlike Thuja isolates, non-Thuja were unable to increase thujaplicin tolerance during three serial generations on liquid medium containing thujaplicins. Long exposure of non-Thuja isolates to T. plicata heartwood under field conditions did not increase their thujaplicin tolerance. Thuja isolates may be able to adapt the enzyme systems blocked by thujaplicin or to detoxify thujaplicins. These results have significance for control of Poria weirii. Planting Thuja plicata in and around infection centers caused by non-Thuja, isolates could limit their size by reducing the number of root contacts between susceptible species.

description: We calculate contained and upward muon flux and contained shower event rates from neutrino interactions, when neutrinos are produced from annihilation of the dark matter in the Galactic Center. We consider model-independent direct neutrino production and secondary neutrino production from the decay of taus, W bosons and bottom quarks produced in the annihilation of dark matter. We illustrate how muon flux from dark matter annihilation has a very different shape than the muon flux from atmospheric neutrinos. We also discuss the dependence of the muon fluxes on the dark matter density profile and on the dark matter mass and of the total muon rates on the detector threshold. We consider both the upward muon flux, when muons are created in the rock below the detector, and the contained flux when muons are created in the (ice) detector. We also calculate the event rates for showers from neutrino interactions in the detector and show that the signal dominates over the background for $150 {\rm GeV}

description: The rare decay B -> K* (-> K pi) mu+ mu- is regarded as one of the crucial channels for B physics as the polarization of the K* allows a precise angular reconstruction resulting in many observables that offer new important tests of the Standard Model and its extensions. These angular observables can be expressed in terms of CP-conserving and CP-violating quantities which we study in terms of the full form factors calculated from QCD sum rules on the light-cone, including QCD factorization corrections. We investigate all observables in the context of the Standard Model and various New Physics models, in particular the Littlest Higgs model with T-parity and various MSSM scenarios, identifying those observables with small to moderate dependence on hadronic quantities and large impact of New Physics. One important result of our studies is that new CP-violating phases will produce clean signals in CP-violating asymmetries. We also identify a number of correlations between various observables which will allow a clear distinction between different New Physics scenarios.

description: We investigate hadrons and direct photon production in pp and pA collisions at the energies of RHIC and LHC within the color-dipole approach employing various saturation models. We show that greatest sensitivity to saturation effects is reached at very forward rapidities for pp collisions at LHC (\sqrt{s}=14 TeV). The ratio of direct-photon to pion production can be about 20-10 (at η=7-8). Therefore, direct photon production at forward rapidities should provide a rather clean probe. We calculate the rapidity dependence of the invariant cross-section and find some peculiar enhancement at forward rapidities which is more pronounced for direct photon production. We show that this peak is further enhanced by saturation effects. We provide predictions for the nuclear modification factor R_{pA} for pions and direct photon production in pA collisions at LHC energy at midrapidity. We show within various saturation models that the pion Cronin enhancement at RHIC is replaced by a moderate suppression at LHC energy at midrapidity due to gluon shadowing effects. Cronin enhancement of direct photons can survive at LHC energy within models with a larger saturation scale.

description: We give an explicit superspace propagator for the chiral scalar field strength of 10D IIB supergravity on an AdS5 x S5 background. Because this space is conformally flat, the propagator is very simple, almost identical to that of flat space. We also give an explicit expansion over the Kaluza-Klein modes of S5. The fact that the full propagator is so much simpler suggests that, as in 2D conformal field theory, AdS/CFT calculations would be simpler without a mode expansion.

Scott of the Antarctic: The Conservation of a Story
Creators: name: Murray, C
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis examines the present status and enduring significance of the story Scott of the Antarctic.‚ÄövÑvp It critically reviews the story's century-long history of interpretation and, via literary analysis, considers its meaning for a contemporary audience. It argues that while Captain Robert Scott's historic hut is being conserved as an icon of the heroic era of Antarctic exploration, the story which gives that hut its meaning is in a less satisfactory condition and is also in need of conservation. In keeping with the twofold nature of its subject‚ÄövÑvÆa story which is based on fact‚ÄövÑvÆthe thesis acknowledges both historiographical and literary critical perspectives. In addition, it draws on a wide range of data: manuscript letters and journals, newspaper and magazine commentary, historical monographs, biographies, literary works and film. The thesis reviews recent scholarly commentary on Scott's story and identifies a variety of shortcomings. These include the polarized nature of the discussion, heavy uncritical use of a single influential debunking biography and a concomitant neglect of earlier sources. A detailed analytical survey of the story's interpretation, from its genesis to the present, highlights principal themes and the influence of intellectual fashions. Veneration of the central character has always been accompanied by criticism. But judgements of Scott's last expedition necessarily lack full knowledge of the circumstances, and many exhibit partisanship, faulty reasoning and the bias of hindsight. Two aspects of the story that have remained surprisingly unexamined are critiqued: the saintly reputation of Lawrence Oates, and the methods and accounts of the other contender for the South Pole, Roald Amundsen. Despite some recent favourable appraisals of Scott, evidence is presented that the character assassination that began in the late 1970s persists today. The final part of the thesis directs attention away from judicial and historical debates, and seeks the story's deeper resonances through literary analysis. Although the quality of Scott's writing and the tragic nature of his story are often mentioned, they have previously received scant critical attention. Aspects of the explorer's literary skill are examined, and comparisons explored between his story and Greek tragedy as described in Aristotle's Poetics. The discussion locates a large part of the transhistorical meaning of Scott of the Antarctic‚ÄövÑvp in its tragic qualities, and concludes by considering how the story's potential has been exploited in imaginative renderings.
The establishment of the dosage-mortality curve for an aphid : a problem in methodology.
Creators: name: Pearson, William Daniel
Publisher: name: University of British Columbia
Year: 2011

description: A reliable technique for establishing the dosage: mortality curve for an aphid is described. Standardized conditions of rearing, collecting, treating and post-treatment holding are combined with application of measured droplets of malathion in acetone solution to individual aphids. The importance of each of these factors is discussed. The LD₅₀ of malathion to the pea aphid is 23.6 nanograms per aphid. The 95% fiducial limits about this estimate are 18.4 and 31.4 nanograms per aphid. The slope (± S,E.,n = 7) of the log-dosage: probit-mortality line is 5.5 ± 0.4. The mathematical and biological criteria used to evaluate the technique, and the possible application of the technique to selection and studies of insecticide resistant clonal lines of aphids are also discussed. Exposure of aphids on treated glass surfaces, and spraying with solutions or emulsions are also investigated and are discussed. These methods are unsatisfactory for investigation of the genetics and toxicology of insecticide resistance in aphid populations.

description: The construction industry is a conservative sector with limited innovation improvements compared to other industrial sectors. The construction industry has a considerably bad reputation in regard to its carbon footprint. Based on these facts, the construction industry is pressed to change and to be more sustainable by using technological innovations which, are provided by the so-called third industrial revolution. These innovations are related to the development of the material science, robotics, environmental and computer sciences. The application of these innovations promises to transform the traditional construction to a digital construction. A main aspect of digital construction is the adoption of digital fabrication methods. The most well-known digital fabrication method is the additive manufacturing method. The research interest about the additive manufacturing methods in construction industry is rising in the recent years. This project studies the use of cementitious materials in additive manufacturing methods with emphasis on printable behaviour of 3D Printing Concrete (3DPC). This study presents all the necessary knowledge gained from the relevant literature review about 3DPC and its applications. Also, conclusions are drawn about the printable properties of 3DPC through the analysis of preliminary experimental outcomes.

Within the resolution of our measurements, the low temperature limiting C/T is found to be linear in field, i.e. we find no evidence for a Volovik effect associated with nodal quasiparticles in either the clean or dirty limit. We discuss possible reasons for this apparent contradiction.

description: Many important invariants for matroids and polymatroids, such as the Tutte polynomial, the Billera-Jia-Reiner quasi-symmetric function, and the invariant $\mathcal G$ introduced by the first author, are valuative. In this paper we construct the $\Z$-modules of all $\Z$-valued valuative functions for labeled matroids and polymatroids on a fixed ground set, and their unlabeled counterparts, the $\Z$-modules of valuative invariants. We give explicit bases for these modules and for their dual modules generated by indicator functions of polytopes, and explicit formulas for their ranks. Our results confirm a conjecture of the first author that $\mathcal G$ is universal for valuative invariants.

Transforming histories: The visual disclosure of contentious pasts.
Creators: name: Gough, J
Publisher: name: University Of Tasmania
Year: 2023

description: This project investigates new ways to apprehend and visually reconfigure aspects of concealed or disputed pasts.' The intention of this work is to enable a viewer to experience obscured or nearly forgotten narrativesnarratives of memory, time, absence, location and representation. The works utilise found and constructed objects and techniques from the visual arts, the museum, the library, the shop, the garden. One common methodology is the arrangement of multiple objects to activate a surface optically, and encourage a viewer to read it as a means of temporarily holding the objects in place. In doing so they find themselves part of the work. These pieces are experiments in understanding how viewers can travel around an artwork and in this process move their position back and forth, flickering between past and present and personal and national memory. Most works incorporate ideas of movement or stasis either technically or in the story which they may be partially relating to the viewer. This suggestion of waiting or of motion summons a viewer to enter into the work as a timekeeper. This is an anxious position where many of the materials inviting curiosity, and initially implying the humorous, accrue a sinister edge as the viewer reaches a point of understanding his/her caged predicament within the work. For the first time all these works will be exhibited together. Showing them in different locations raised considerations of setting both spatial and conceptual - and recent works have developed that are about journeying across time and place. The investigation has emerged from very personal considerations of the place of memory, forgetting, loss, denial and the potency of the past within my own family. Artists who have explored similar terrain, visually reconfiguring the marginal or the textual, include Gordon Bennett, Fiona Foley, Tracey Moffatt, Christian Boltanski and Fred Wilson. This project has been a journey through many stories across time. These have inevitably been incorporated into my own memory, my own life, and my own increasingly open narrative of deciphering self in the process of relating the past. Each work has been built from the outcomes of the last, and represents a claiming within a larger consideration of ways to personally invoke and involve nation, viewer and self in acknowledging our entangled histories.
Full-sky lensing shear at second order

description: We compute the reduced cosmic shear up to second order in the gravitational potential without relying on the small angle or thin-lens approximation. This is obtained by solving the Sachs equation which describes the deformation of the infinitesimal cross-section of light bundle in the optical limit, and maps galaxy intrinsic shapes into their angular images. The calculation is done in the Poisson gauge without a specific matter content, including vector and tensor perturbations generated at second order and taking account of the inhomogeneities of a fixed redshift source plane. Our final result is expressed in terms of spin-2 operators on the sphere and is valid on the full sky. Beside the well known lens-lens and Born corrections that dominate on small angular scales, we find new non-linear couplings. These are a purely general relativistic intrinsic contribution, a coupling between the gravitational potential at the source with the lens, couplings between the time delay with the lens, couplings between two photon deflections, as well as non-linear couplings due to the second-order vector and tensor components. The inhomogeneity in the redshift of the source induces a coupling between the photon redshift with the lens. All these corrections become important on large angular scales and should thus be included when computing higher-order observables such as the bispectrum, in full or partially full-sky surveys.

description: Existing approaches for early-stage bladder tumor diagnosis largely depend on invasive and time-consuming procedures, resulting in hospitalization, bleeding, bladder perforation, infection and other health risks for the patient. The reduction of current risk factors, while maintaining or even improving the diagnostic precision, is an underlying factor in clinical instrumentation research. For example, for clinic surveillance of patients with a history of noninvasive bladder tumors real-time tumor diagnosis can enable immediate laser-based removal of tumors using flexible cystoscopes in the outpatient clinic. Therefore, novel diagnostic modalities are required that can provide real-time in vivo tumor diagnosis. Raman spectroscopy provides biochemical information of tissue samples ex vivo and in vivo and without the need for complicated sample preparation and staining procedures. For the past decade there has been a rise in applications to diagnose and characterize early cancer in different organs, such as in head and neck, colon and stomach, but also different pathologies, for example, inflammation and atherosclerotic plaques. Bladder pathology has also been studied but only with little attention to aspects that can influence the diagnosis, such as tissue heterogeneity, data preprocessing and model development. The present study presents a clinical investigative study on bladder biopsies to characterize the tumor grading ex vivo, using a compact fiber probe-based imaging Raman system, as a crucial step towards in vivo Raman endoscopy. Furthermore, this study presents an evaluation of the tissue heterogeneity of highly fluorescent bladder tissues, and the multivariate statistical analysis for discrimination between nontumor tissue, and low- and high-grade tumor. © 2019 The Authors.

description: The compressive creep deformation behavior of a Co-base single-crystalline superalloy is studied in the high temperature / low stress regime at 950°C/150 MPa. Emphasis is placed on the mechanisms causing the double minimum creep behavior consisting of a local and a global creep rate minimum. The local minimum occurs at ∼0.2% strain with dislocation accumulation at γ/γ′ interfaces after bowing out of dislocations in horizontal matrix channels. Plate-like rafting occurring normal to the applied stress axis in the early creep stages is regarded as the primary reason for the decreasing creep rate until the global minimum takes place at ∼0.8% strain. In the final creep stage following the global minimum the creep rate accelerates due to coarsening and extensive precipitate shearing. The shearing by partial dislocations leads to the formation of numerous stacking faults, nano/microtwins, and occasionally to the formation of small amounts of ordered D019-Co3W precipitates. The reasons for twinning and second phase formation as well as differences of the deformation mechanisms between Co- and Ni-base superalloys during double minimum creep are discussed in detail in this work.

description: Using the eigen-decomposition method, we investigated the plasmonic modes in a two-dimensional quasicrystalline array of metal nanoparticles. Various properties of the plasmonic modes, such as their symmetry, radiation loss and spatial localization are studied. Some collective plasmonic modes are found to be leaky with out-of-plane radiation loss, but some modes can have very high fidelity. To facilitate the analysis on the complex behavior of the collective plasmonic modes, we considered a trajectory map in a three dimension parameter space defined by the frequency of the mode, the participation ratio of the mode that gives the spatial distribution, and the eigenvalue that is related to the inverse lifetime of the mode. With the help of the trajectory map method, we found that there are modes that are localized in some special ways and the plasmonic mode with highest spatial localization and highly fidelity is found to be a type of anti-phase ring mode. In general, different localized modes have very different radial decay behaviors. There is no special relationship between the fidelity of the modes and their spatial localization.

Professional Socialisation and Identity Formation in Rural Health Education
Creators: name: Dalton, Lisa
Publisher: name: University Of Tasmania
Year: 2023

description: The study offers a critical theoretical consideration of underlying perspectives informing rural health education in an undergraduate nursing, medical and pharmacy program. A new research approach was developed and tested for examining the effects of different individuals and groups (from academics to rural health practitioners to undergraduate nursing, medical and pharmacy students) using different patterns of language in the socialising process of rural health education. The thesis describes and demonstrates the use of critical discourse analysis as a means of facilitating critical awareness and stimulating research practice focussing on rural health education. Critical discourse analysis applies to a range of semiotic methods for examining text, such as natural instances of written and spoken language, with the objective of gaining insights into the meanings of a text and what it signifies. Emphasis is placed on the way individuals and groups use language, where texts construct the social world and influence the way identity is formed.
Productivity of the macrophytes of Marion Lake, B.C.
Creators: name: Davies, Gordon Stanley
Publisher: name: University of British Columbia
Year: 2011

description: The in situ productivity of both the phytoplankton and the macro- phytes in Marion Lake, B.C., was determined from April 1966 through September 1966, by using ¹⁴C techniques. The uptake of NaH¹⁴CO₃ was measured in selected macrophytes by enclosing them in plexiglass chambers. These plants were then combusted in oxygen, and the ¹⁴CO₂ was absorbed in toluene-POPOP-ethanolamine. Radioassay was accomplished by liquid scintillation. In addition to the ¹⁴C method, an organic weight method was used to measure macrophytic productivity. The productivity of the macrophytes was always higher than that of the phytoplankton. There was a considerable difference in the estimates of the macrophyte productivity arrived at by the two different methods, and reasons for this are discussed. The total productivity of the lake is very low when compared with lakes of similar latitudes because of low phytoplankton productivity. It is concluded that in Marion Lake the macrophytes are more important primary producers than the phytoplankton. The difficulty of comparing data between this and other studies is discussed, and the need for standardization of methods is emphasized.

The Training and Education Needs of Emergency Medicine Doctors working in Rural and Regional Australia
Creators: name: Arvier, Peter
Publisher: name: University Of Tasmania
Year: 2023

description: For professional and lifestyle reasons, most specialist doctors (including emergency medicine specialists) choose to live and work in major metropolitan centres. In rural and regional hospitals, emergency presentations are generally dealt with by 'non-specialist' doctors, often with limited peer support and minimal specialist backup. Recruitment of suitably trained medical staff for rural and regional hospitals is increasingly difficult. The doctors working in the emergency departments of these smaller hospitals are a mix of junior medical staff, Career Medical Officers, short term locums, and part time General Practitioners - with a high reliance on overseas trained doctors from widely varying backgrounds. While undergraduate and general practice training in rural areas has been extensively studied, there has been relatively little attention given to postgraduate specialty training and few studies on adverse events and health outcomes in rural areas.

Data quality
Dashboard
Kahn Framework
OMOP
Common data model

description: The Data Quality Dashboard (DQD) developed as part of EHDEN Work Package 4 provides a comprehensive, customizable, and transparent way to both evaluate and communicate the quality of an OMOP CDM instance. It provides both the code to run data quality checks against an OMOP CDM instance, as well as visualising the results in a web application. The data quality checks were organised using the widely accepted Kahn Framework for data quality. This groups the checks types in categories: Conformance, Completeness and Plausibility. Each category has one or more subcategories and are evaluated in two contexts: Validation and Verification. Each SME and data partner will be expected to run the Data Quality Dashboard on the data at their site once it is converted to the OMOP CDM. Initially it can be used to assess whether OMOP Standards such as primary key constraints and concept domain restrictions are being followed. Thinking specifically of the EHDEN federated network, providing an interactive data quality report for each participating site will provide evidence not only that OMOP specifications were followed correctly but also to demonstrate that the necessary due diligence was done to ensure that the data are of research quality. We believe the DQD is a strong foundation for data quality reporting, and a key tool to ensure confidence in the evidence generated through the EHDEN federated network.

Unsteady Flow and Transition Phenomena in an Axial Flow Compressor
Creators: name: Henderson, AD
Publisher: name: University Of Tasmania

description: The unsteady mid-span aerodynamics of an outlet stator row in a 1.5-stage low-speed axial compressor is investigated experimentally and numerically. Two stator blade rows with characteristically dierent blade proles are studied: one of standard British C4 section and a controlled diusion (CD) blade with a circular arc leading edge prole. A turbulence grid placed at compressor inlet is used to generate turbulence characteristics similar to those occurring in an embedded stage in a multi-stage axial compressor. The stator inlet ow is studied using hot-wire anemometry and compared with previous measurements made in the natural low inlet turbulence conguration of the research compressor. Increased turbulence level enhances the dispersion of inlet guide vane (IGV) wakes. This modies the interaction between IGV and rotor blade wakes, leading to a more circumferentially uniform ow eld at entry to the stator with signicantly lower periodic unsteadiness. Laminar-turbulent transition on a C4 stator blade is studied using an array of surface-mounted hot-lm sensors. Comparisons with measurements made at low inlet turbulence show that the increased inlet turbulence level reduces the extent of periodic transitional ow on the stator blade surface. The blade element behaviour ow behaviour at high inlet turbulence closely resembles the low inlet turbulence case with the stator immersed in IGV wake turbulence. The circular arc leading edge prole of the CD stator produces rapid acceleration and deceleration at the stator leading edge. The in uence of this velocity spike on the stator boundary layer development and transitional ow behaviour is studied using an array of surface mounted hot-lm sensors. A region of favourable pressure gradient on the suction surface following the leading edge spike has a stabilising eect on the boundary layer, with a large region of ow in a laminar or transitional state. Turbulent spots and instability phenomena in this region are examined for convection speed, growth rate and evidence of relaminarisation. In contrast, the ow on the pressure surface becomes turbulent near the leading edge. The study shows that compressor blade leading edge proles have a major in uence on boundary layer development over the whole surface. The eect of upstream rotor wake passing on the stability of stator blade boundary layers is examined. The unsteady quasi-three dimensional ow solver, UNSFLO, is used to interpret surface hot-lm data and unsteady laminar ow behaviour at the leading edge of both C4 and CD stators. Rotor wake chopping is found to stabilise the pressure surface boundary layer and destabilise the suction surface boundary layer. Examination of hot-lm data points to the leading edge as the principal receptivity site for transitional ow phenomena occurring on the suction surface of both the C4 and CD blading.

description: Science requires open, reproducible, and collaborative approaches to maximize efficiency and deliver improved outcomes. These proceedings summarize outcomes of the Spatial Data, Analysis and Modelling Forums organized as part of the R Learning and Development series by the Fisheries and Ocean Canada (DFO) Science Sector (Maritimes and Pacific Regions) in 2020. These forums and workshops enabled Science staff to: Exchange information about strategic planning and workflows to effectively organize data, code, and tools to support spatial analysis and modelling, Gain insight on how different data products could be, or have already been, used to inform spatial analysis and modelling, Share perspectives on the relevant considerations for using spatial data products and datasets, or the predictors in general, and any of the limitations users should be aware of, Learn about new spatial data products and existing platforms for sharing spatial data, Discuss the limitations of the available data products in terms of extent, resolution, quality and underlying assumptions. These proceedings provide an overall summary of this learning and development series, describing the materials, presentations, questions, and discussions. The main intent of this initiative was to provide a forum for DFO staff to present their ongoing work and issues in relation to spatial tools, data, analysis and modelling. A secondary goal was to learn how various programs and regions were resolving these issues and to build a common understanding of each other’s perspectives. This initiative was also conceived with the intent to foster collaborations, by helping DFO staff connect with colleagues that have shared challenges or interests. The information gleaned from discussions and participant surveys were used to guide and support future learning opportunities such as statistical modelling and programming language training. It is our hope that the information gathered from these learning and development opportunities can support already established working groups and task forces currently tackling data discovery and management challenges at DFO. Based on the presentations and discussions that followed during these events we present recommendations for increasing reproducibility and institutional efficiency in spatial analyses and modelling efforts.

description: We review two methods used to approach the condensation of defects phenomenon. Analyzing in details their structure, we show that in the limit where the defects proliferate until occupy the whole space these two methods are dual equivalent prescriptions to obtain an effective theory for the phase where the defects (like monopoles or vortices) are completely condensed, starting from the fundamental theory defined in the normal phase where the defects are diluted.

description: In 1934, Jordan et al. gave a necessary algebraic condition, the Jordan identity, for a sensible theory of quantum mechanics. All but one of the algebras that satisfy this condition can be described by Hermitian matrices over the complexes or quaternions. The remaining, exceptional Jordan algebra can be described by 3x3 Hermitian matrices over the octonions. We first review properties of the octonions and the exceptional Jordan algebra, including our previous work on the octonionic Jordan eigenvalue problem. We then examine a particular real, noncompact form of the Lie group E6, which preserves determinants in the exceptional Jordan algebra. Finally, we describe a possible symmetry-breaking scenario within E6: first choose one of the octonionic directions to be special, then choose one of the 2x2 submatrices inside the 3x3 matrices to be special. Making only these two choices, we are able to describe many properties of leptons in a natural way. We further speculate on the ways in which quarks might be similarly encoded.

description: Paleosoil accretions of carbonates in the Tandilia system (Southern Pampas, Argentina) dated to the lower/middle Pleistocene age are locally referred to as tosca. The characterization of this indurated layer of carbonates were analyzed via a biophysicochemical approach, including, physicochemical analysis of soils, mineral x-ray diffraction of the tosca, and microbial diversity of modern soils and tosca layers. The minerals found within tosca were calcite, albite, muscovite, quartz, orthoclase and dolomite in order of most to least abundant. The microbial metataxonomics of tosca was described for the first time. The most abundant microorganisms in tosca were g_Geobacter, g_Pseudonocardia and p_Gemmatimonadetes2 and redundancy analysis of physicochemical parameters and relative microbial abundances revealed positive correlations between Nitrospirae and calcium ions, while mineral and microbial correlations associated Gemmatimonadetes and Firmicutes with calcite and dolomite presence. Magnetospirillum, Geobacter and Bacillus were present in the tosca and the soil above, indicating possible prenucleation sites for calcite and dolomite. Core microorganism abundance was >80% throughout horizons including tosca, hence either microbial entrapment via calcium carbonate precipitation or microbial leaching occurred within this layer.
