Provision for music education in the primary school curriculum : school solutions
Creators: name: Gora, Christine
Publisher: name: University Of Tasmania
Year: 2023

description: The developing trend towards common curricular frameworks for the arts disciplines is examined in the context of a discussion of the past and present educational, social and economic influences on the arts in Australia. The philosophical foundations underlying National and State curricula are explored in depth and the implications for music curriculum design and delivery in the primary school are established. As curriculum ideals are not always evident in classroom practice, this research examines actual practice through the analysis of results from a survey questionnaire distributed to primary school specialist music teachers in the Hartz district in southern Tasmania. Changes affecting human and physical resourcing levels, and as a consequence timetabling and programs, are examined. The extent to which current music documents and arts frameworks influence actual programs is ascertained. The nature of the curriculum choices being made and individual school solutions, are analysed. While a music education for all children forms the foundation of many curricular ideals this research will seek to establish the extent to which equity of provision has been achieved. Movements towards a user-pays system and the widening gulf between policy and practice are shown as the inevitable result of rationalisation philosophies. Therefore despite current policy emphases on \music for all\" a relationship is shown between the range and type of school solutions for the provision of music education and the school's socio-economic status location and size. All of these have access and equity implications for music teaching."
Secondary autogenic succession in the southern Rocky Mountain Trench

description: The patterns and rates of forest regeneration on a critical wildlife winter range on the floor of the trench, known locally as Premier Ridge were examined in this study. A nearby western wall of the trench was also investigated to ascertain the effect of elevation on forest regeneration and understory productivity. Forest regeneration in a community which has remained unforested for several as years has pronounced effects on the floristic dynamics and productivity of the understory. On Premier Ridge the greatest floristic change was a rapid increase in pinegrass and a. corresponding decrease in the abundance of all other grass species as the forest regeneration progressed. Forbs varied widely in abundance while shrubs were slower to react to changes in the overstory. Similar trends were observed on Estella Mountain. Productivity of the grass component on the unforested sites was four times that of the forested sites. The production of forbs and some species of shrubs also declined as forest regrowth began. One species, bearberry, increased under light forest canopies. The reduction in productivity and the changes in species composition of-the understory which occur in regenerating forest communities, appear to be detrimental to foraging populations of wild and domestic ungulates. Cattle seem to prefer to graze the open, unforested areas, and as regeneration proceeds, the acreage which they will readily use diminishes. Since there have been few reductions in stock numbers to compensate for this range shrinkage, local overgrazing has become more widespread. The regrowth of the forest reduces the grass, both in terms of quality and quantity. This is the most important component in the diet of cattle and most of the wildlife species using the Premier Ridge area. In addition, bitterbrush, used in the summer by cattle and during the winter by big game species, is quickly eliminated by forest regeneration. Bearberry, which may be used by wildlife to some extent, increases under forest cover. This component does not approach in value or usefulness, the losses that the other components represent to grazing animals. The trees of the south and southwestern aspects are characterized by relatively slow growth rates. Forage production on these slopes is modest; if grazing animals are deemed desirable in the future economy of the East Kootenay, these areas should remain treeless. Growth rates are more favourable on the north and northeast aspects, which are less frequently used as foraging areas by winter wildlife, but may be used as shelter or bedding areas.
Space and myth in Surakarta Kasunanan Palace, Indonesia : a preliminary investigation of spatial and mythical qualities of the palace and how they relate to the power and authority of the king/dom
Creators: name: Dewanto, W
Publisher: name: University Of Tasmania
Year: 2023

description: Surakarta Kasunanan palace, in central Java, is an important part of the heritage of the Indonesian nation. It is regarded as a centre of Javanese culture. The architecture of the palace represents the complexity of Indonesian culture, where local tradition and external social, cultural and religious influences are manifested in the form and structure. Surakarta Kasunanan palace as a whole is considered a sacred place, gives a religious impression and reflects the characteristics of the kingdom. Within the palace, each component becomes a symbol of Javanese philosophy resulting from a combination of various beliefs, including indigenous Javanese animism, Hinduism, Buddhism and Islam. This study attempts to investigate the spatial and mythical qualities of the palace and to analyse how they relate to the power and authority of the king as the centre of a Javanese Islamic kingdom. It is anticipated that this will provide an alternative approach in the study of traditional architecture, where emphasis is placed on the cultural, social and political aspects which influence the physical forms. A large portion of the work in this investigation has dealt with the arrangement of the palace. Yet, more emphasis has been placed on aspects of the relationship between people and their physical surroundings, than on the information about its physical character. In short, this research is an attempt to discover, through a variety of methods, the spiritual effects that the physical world exerts upon Javanese people. As the history of Surakarta Kasunanan palace has been the foundation of thinking about values and norms of Javanese culture in the last two centuries, so the history of its architecture has influenced the criteria that inform our view of Javanese architecture. This thesis examines the Surakarta Kasunanan palace, its history, its evolution, its built form, the myth behind the palace, and the political and social backgrounds in order to understand the role of the palace as a symbol of the power and authority of the king, and as a model of traditional Javanese architecture. The general purpose of the research is to address questions concerning aspects of Javanese architecture, particularly the space, layout and form of the buildings, and how these related to users' behaviour. The investigation focuses on the Surakarta Kasunanan palace and the question how the mythology surrounding it was used to reinforce the power and authority of the king.

description: We analyze isospin breaking through quark mass differences and virtual photons in the pion-nucleon scattering lengths in all physical channels in the framework of covariant baryon chiral perturbation theory. The so-called triangle relation is found to be violated by about 1.5 %. We encounter a substantial isospin-breaking correction to neutral-pion-nucleon scattering beyond Weinberg's prediction due to a cusp effect. Finally, the application to hadronic atoms is briefly discussed.

description: The possible experimentally observable signal in momentum space for the critical point, which is free from the contamination of statistical fluctuations, is discussed. It is shown that the higher order scaled moment of transverse momentum can serve as an appropriate signal for this point, provided the transverse momentum distribution has a sudden change when energy increases passing through the critical point. A 2-D percolation model with a linear temperature gradient is constructed to check this suggestion. A sudden change of third order scaled moment of transverse momentum is successfully observed.

description: This paper describes a new link between combinatorial number theory and geometry. The main result states that A is a finite set of relatively prime positive integers if and only if A = (K-K) \cap N, where K is a compact set of real numbers such that for every real number x there exists y in K with x \equiv y mod 1. In one direction, given a finite set A of relatively prime positive integers, the proof constructs an appropriate compact set K such that A = (K-K) \cap N. In the other direction, a strong form of a fundamental theorem in geometric group theory is applied to prove that (K-K)\cap N is a finite set of relatively prime positive integers if K satisfies the appropriate geometrical conditions. Some related results and open problems are also discussed.

description: The charge spreading of ground and excited states of Klein-Gordon particles moving in a Coulomb potential is quantitatively analyzed by means of the ordinary moments and the Heisenberg measure as well as by use of the most relevant information-theoretic measures of global (Shannon entropic power) and local (Fisher's information) types. The dependence of these complementary quantities on the nuclear charge Z and the quantum numbers characterizing the physical states is carefully discussed. The comparison of the relativistic Klein-Gordon and non-relativistic Schrodinger values is made. The non-relativistic limits at large principal quantum number n and for small values of Z are also reached.

description: For a given quadratic equation with any number of unknowns in any free group F, with right-hand side an arbitrary element of F, an algorithm for solving the problem of the existence of a solution was given by Culler. The problem has been studied by the authors for parametric families of quadratic equations arising from continuous maps between closed surfaces, with certain conjugation factors as the parameters running through the group F. In particular, for a one-parameter family of quadratic equations in the free group F_2 of rank 2, corresponding to maps of absolute degree 2 between closed surfaces of Euler characteristic 0, the problem of the existence of faithful solutions has been solved in terms of the value of the self-intersection index mu: F_2 --> Z[F_2] on the conjugation parameter. The present paper investigates the existence of faithful, or non-faithful, solutions of similar families of quadratic equations corresponding to maps of absolute degree 0.

description: This fluid dynamics video presents experiments and simulations of gravity-driven particulate jets in viscous fluids at low Reynolds number. An initially straight jet is shown to develop varicose modulations of its diameter as it sediments under the action of gravity. While this instability is qualitatively reminiscent of the classical Rayleigh-Plateau instability for immiscible fluids, its mechanism has yet to be understood as neither inertia nor surface tension play a role in the case of a dilute suspension at Re=0.

Portable monitors for flow injection analysis with potentiometric multiple ion sensors
Creators: name: Dimitrakopoulos, Telis
Publisher: name: University Of Tasmania
Year: 2023

description: The use of multi-sensing portable monitors is of increasing importance for many applications in modern technology. This thesis reports on the development of a new portable battery-powered flow injection potentiometric (FIP) system suitable for remote-site monitoring that can utilise a range of ion-selective electrodes (ISEs) or arrays of coated-wire electrodes (CWEs) as detectors. A number of different designs were developed and evaluated for a variety of applications. Portable FIP systems employing: (1) a commercial iodide ISE as a single electrode detector, and (2) a tungsten / tungsten-oxide wire electrode employed as a pH sensor were initially developed. The performance of the iodide electrode exhibited near-Nernstian response over a wide concentration range in the FIP mode. The tungsten / tungsten-oxide electrode exhibited a subNernstian response between the pH range 2 and 11, and was used to determine the pH of various samples in the FIP mode. Three commercial planar type ISEs (nitrate, potassium and sodium) were arranged in a three-ISE array and used in the portable FIP system. The potassium and sodium ISEs exhibited Nernstian responses, while the nitrate ISE exhibited a near-Nernstian response. The accuracy of the ISE-array was studied and validation of this system was performed with various mineral water samples in the FIP mode. An eight electrode flow-through cell was developed in a portable HP system and evaluated in the FIP mode with metallic silver electrodes. These were each anodised with iodide and the responses of the individual electrodes to silver and iodide standard solutions were studied. Individual photo-cured bisphenol A epoxydiacrylate membrane based CWEs for ammonium, calcium, hydrogen, nitrate and potassium were developed and evaluated using silver wire electrodes in the eight-electrode flow cell described above. Each photo-cured CWE exhibited Nernstian response over a wide concentration range in the steady-state mode and was selective and fast responding taking <5 seconds to attain 90% of the steady-state value, making them ideal for a multi-CWE arrangement in FIP. These photo-cured CWEs were successfully used to determine the respective ions in various water samples. Three multi-CWE arrangements employing the photo-cured membranes mentioned above have been investigated in the FIP mode; namely (1) a two sensor array consisting of ammonium and hydrogen CWEs; (2) a four sensor array consisting of calcium, nitrate, potassium CWEs and a Ag/AgC1 wire electrode; and (3) a six sensor array consisting of ammonium, calcium, hydrogen, nitrate and potassium CWEs and a Ag/AgC1 wire electrode. The multi-CWE arrangements were used to measure the respective ions simultaneously in various water samples in the PIP mode.

description: We analyze the form of the fermionic propagator for 2D fermions interacting with massless overdamped bosons. Examples include a nematic and Ising ferromagnetic quantum-critical points, and fermions at a half-filled Landau level. Fermi liquid behavior in these systems is broken at criticality by a singular self-energy, but the Fermi surface remains well defined. These are strong-coupling problems with no expansion parameter other than the number of fermionic species, N. The two known limits, N >>1 and N=0 show qualitatively different behavior of the fermionic propagator G(ε_k, ω). In the first limit, G(ε_k, ω) has a pole at some ε_k, in the other it is analytic. We analyze the crossover between the two limits. We show that the pole survives for all N, but at small N it only exists in a range O(N^2) near the mass shell. At larger distances from the mass shell, the system evolves and G(ε_k, ω) becomes regular. At N=0, the range where the pole exists collapses and G(ε_k, ω) becomes regular everywhere.

description: It is a challenge to explain why neutrinos are so light compared to other leptons. Small neutrino masses can be explained if right-handed fermions propagate in large extra dimensions. Fermions propagating in the bulk would have implications on Higgs boson decays. If the Higgs boson is discovered at the Large Hadron Collider (LHC), a detailed analysis may reveal the presence of large extra dimensions. This paper reviews the status of large extra-dimensional models in the context of the current limits on Higgs boson masses and the fundamental Planck scale in extra dimensions.

description: We present experimental sensitivity for the production of a fourth-generation Majorana neutrino ($N$) via an s-channel $Z$ boson $Z\to NN \to W\ell W\ell$ at hadron colliders. This channel has not been studied for the Tevatron dataset with $\int \mathcal{L}=5 $ fb$^{-1}$, where we find that a single experiment could significantly extend current 95% C.L. mass lower limits, to $m_N>175$ GeV$/c^2$, or report $3σ$ evidence for the $N$ if $m_N<150$ GeV$/c^2$. With 5 fb$^{-1}$, a single LHC experiment at $\sqrt{s}=10$ TeV could expect t o set a 95% C.L. mass lower limits of $m_N>300$ GeV$/c^2$, or report 3$σ$ evidence for the $N$ if $m_N<225$ GeV$/c^2$.

Development of an ion chromatographic system suitable for monitoring the gold cyanidation process
Creators: name: Fagan, Peter Andrew
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis reports the development of new ion chromatographic (IC) methodology suitable for monitoring the gold cyanidation process. This project continues a series of related investigations involving the development of IC techniques, based mainly on reversed-phase ion interaction chromatography (RPIIC), for the speciation of metallo-cyanide complexes formed during the cyanidation of auriferous ores [1-4]. The focus of this earlier work was concerned with the development of suitable methodology for the analysis of the products of the cyanidation process, such as those found in tailings dams and environmental samples. In contrast to the previous investigations, this project has focused on the determination of the various cyano species found during the extraction stage of the gold cyanidation process. These cyano species include uncomplexed ('free') cyanide, metallo-cyanide complexes, thiocyanate and cyanate. It should be noted that the terms 'free' and uncomplexed cyanide are not strictly interchangeable, especially in the presence of labile metallo-cyanide complexes. The change in emphasis from environmental monitoring to process control was originally suggested by Metana Minerals, as a means to improve the efficiency of their cyanide leaching operations. It should be emphasised that cyanide (usually added as sodium or calcium cyanide) is the most expensive reagent used during the extraction of gold from ore.

description: This article deals with the possible manifestations of the ongoing process of the celeb-ritization of politics in the view of the language of comments that occur on gossip websites which, in fact, have become the places of the deliberate image-creation of people related to politics. The means of creation comes down to publishing content associated with the private or semi-private lives of people who are engaged in politics. In addition, we can also observe a far-reaching process of the vulgarization and brutalization of the language of comments and entries which is also a specific phenomenon.

description: In order to get a better understanding of amoeba-substrate interactions in the processes of cellular adhesion and directional movement, we engineered glass surfaces with defined local adhesion characteristics at a micrometric scale. Amoeba (Dictyostelium dicoideum) is capable to adhere to various surfaces independently of the presence of extracellular matrix proteins. This paper describes the strategy used to create selective adhesion motifs using an appropriate surface chemistry and shows the first results of locally confined amoeba adhesion. The approach is based on the natural ability of Dictyostelium to adhere to various types of surfaces (hydrophilic and hydrophobic) and on its inability to spread on inert surfaces, such as the block copolymer of polyethylene glycol and polypropylene oxide, named Pluronic. We screened diverse alkylsilanes, such as methoxy, chloro and fluoro silanes for their capacity to anchor Pluronic efficiently on a glass surface. Our results demonstrate that hexylmethyldichlorosilane (HMDCS) was the most appropriate silane for the deposition of Pluronic. A complex dependence between the physicochemistry of the silanes and the polyethylene glycol block copolymer deposition was observed. Using this method, we succeed in scaling down the micro-fabrication of pluronic-based adhesion motifs to the amoeba

Kasimir Malevich and suprematism : art in the context of revolution
Creators: name: Wheeler, Dennis F.
Publisher: name: University of British Columbia
Year: 2011

description: It would seem almost inconceivable that art could, of its own accord, move society towards the kind of ultimate resolution of conflict necessary for an emergence of the egalitarian paradise on earth that was proposed by most Messianic philosophies in the nineteenth century. Art continually appears to be in the process of undermining any attempt by theoretical philosophy to contain or describe it as an absolute. This seems to be the source of much of the irony of art objects and their tacit philosophical implications. We can assume then that there is a somewhat paradoxical basis for the phenomenon of art as we have come to understand it historically. Any object, in order to be meaningful, has to carry a charge. Whether this is of a magical quality or pertains, as we conventionally recognize it, to some social understanding, what we call an ideology, the art-object does not exist without meaning. It is important to realize that I am not drawing a distinction here between ordering or disordering phenomena. Destruction is equally meaningful as construction, these are not value judgments, evil is as present a phenomena as good, and probably as intrinsically human. The concept of creativity that permeates our knowledge and respect for the powers art traditionally held, are historical understandings. As a civilization, we may have done away with mythological stories of our origins, cosmogonies, etc., but we have tended to unconsciously replace them with conceptual, as opposed to imagistic, alternatives, still largely mythic in construction, although we do not popularly recognize them as such. I am using myth here in Levi-Strauss' sense of the word, i.e.: "the unconscious social truths, those principles which provide the broadest base for a society's conception of itself.”¹ One task of this thesis will be to sort out the confusion which has resulted because of the ideological entanglement with mythic (religious) and scientific conceptions that has characterized the central arguments surrounding the arts in the early years of the twentieth century. Revoluntionary Russia now appears as a particularly dense arena for the combat of extreme or polarized beliefs as to the nature of art, and the artist's responsibility relative to an emerging mass consciousness. In this context there was a comparatively conscious merger of ideological propositions into what was previously considered a uniquely aesthetic or pure art production. Such a situation was contingent to the life and work of Kasimir Malevich (1878-1935). My intention is to demonstrate the art historical antecedents to such a period relevant to Malevich’s conceptions and the relationships which interconnect the development of his aesthetic with the philosophical and political concerns of his time. The ethos in which the artist emerges is especially indivisible in this instance from… [abstract continues]

description: No abstracts are to be cited without prior reference to the author. In a context of global warming, and based on the assumptions highlighted in a previous study concerning the importance of Norway pout (Trisopterus esmarkii) for the spatial distribution of saithe (Pollachius virens) and hake (Merluccius merluccius), we investigated the impact of a reduction of prey availability on the saithe stock as a potential consequence of hake recent emergence in the North Sea. As first step, the evaluation of bottom-up processes was done studying environment influence on saithe growth using ICES survey data. The environment was defined by temperature, saithe spawning stock biomass (SSB) and Norway pout total biomass. Estimation of the influence of the environment on saithe weight-at-age was done using generalized linear models. Von Bertalanffy growth function (VBGF), and another related method, were used to estimate growth parameters from VBGF which were, in a second time, put in relation with the environment. In a next step, the results concerning the influence of Norway pout biomass on saithe weight-at-age and/or growth parameters will be implemented in the the stochastic multispecies model (SMS) to assess hake direct effects on Norway pout stock and indirect effects on saithe population growth and stock dynamics.

description: No abstracts are to be cited without prior reference to the author. The structural diversity of ovatoxins (OvTXs) was studied in strains of Ostreopsis cf. ovata isolated from the Gulf of Naples (AZ strains) and grown in culture at Statione Zoologica A. Dohrn. ESILCTOF analysis, with complementary use of positive and negative ion modes revealed the occurrence of twelve palytoxin (PlTX) congeners. Five of them could be OvTX-a, OvTX-b, OvTX-c and OvTX-d/e, known in the literature but with undefined structures except for OvTX-a. Other congeners were indicated to be new having structural variations at the N-containing terminal units connected to the C1-carbon and/or at 115-NH2. The congeners seemed to share a similar carbon-chain backbone, a feature that should be taken into account when applying immunoassays for monitoring. The variances of the terminal units combined with the elusive LC behavior of some analogs should be taken into account when applying LC-MS/MS for determination. The occurrence of other unknown PlTX analogs was also detected, suggesting the need for further studies.

description: The CP asymmetry in neutrino oscillations, assuming new physics at production and/or detection processes, is analyzed. We compute this CP asymmetry using the standard quantum field theory within a general new physics scenario that may generate new sources of CP and flavor violation. Well known results for the CP asymmetry are reproduced in the case of V -A operators, and additional contributions from new physics operators are derived. We apply this formalism to SUSY extensions of the Standard Model where the contributions from new operators could produce a CP asymmetry observable in the next generation of neutrino experiments.

description: No abstracts are to be cited without prior reference to the author. In this study, systematic transect observations of cetaceans were collected in the Norwegian Sea between the 4th and 28th of July 2013. Coherent multi-frequency acoustic recordings and systematic net and trawl station data were collected for analyses of potential relationships between cetacean distribution and the most abundant plankton and fish species. Preliminary results show that killer whales were allocated to the central and northern part of the Norwegian Sea associated with small and loose shoals of adult northeast Atlantic mackerel. Fin whale sightings were made in the northeastern part of the Norwegian Sea and along the coast of Finnmark. White beaked dolphins overlapped with the areas of the fin whale sightings. Humpback whale sightings were made south of Bear Island and also in the northernmost part of the Norwegian Sea. The fin whale, white beaked dolphin and humpback whale observations were associated with high and dense concentrations of juvenile cod and haddock appearing in the upper 50 m of the water column, clearly indicating foraging activity. Fin- and humpback whales are normally associated with krill, amphipods and pelagic fish in this area; this is the first time such significant overlap between large baleen whales and juvenile gadoids has been documented

description: We study the asymptotic expansion of the neutral-atom energy as the atomic number Z goes to infinity, presenting a new method to extract the coefficients from oscillating numerical data. We find that recovery of the correct expansion is an exact condition on the Kohn-Sham kinetic energy that is important for the accuracy of approximate kinetic energy functionals for atoms, molecules and solids, when evaluated on a Kohn-Sham density. For example, this determines the small gradient limit of any generalized gradient approximation, and conflicts somewhat with the standard gradient expansion. Tests are performed on atoms, molecules, and jellium clusters. We also give a modern, highly accurate parametrization of the Thomas-Fermi density of neutral atoms.

description: We perform a stability test of triaxial models in MOdified Newtonian Dynamics (MOND) using N-body simulations. The triaxial models considered here have densities that vary with $r^{-1}$ in the center and $r^{-4}$ at large radii. The total mass of the model varies from $10^8\Msun$ to $10^{10}\Msun$, representing the mass scale of dwarfs to medium-mass elliptical galaxies, respectively, from deep MOND to quasi-Newtonian gravity. We build triaxial galaxy models using the Schwarzschild technique, and evolve the systems for 200 Keplerian dynamical times (at the typical length scale of 1.0 kpc). We find that the systems are virial overheating, and in quasi-equilibrium with the relaxation taking approximately 5 Keplerian dynamical times (1.0 kpc). For all systems, the change of the inertial (kinetic) energy is less than 10% (20%) after relaxation. However, the central profile of the model is flattened during the relaxation and the (overall) axis ratios change by roughly 10% within 200 Keplerian dynamical times (at 1.0kpc) in our simulations. We further find that the systems are stable once they reach the equilibrium state.

description: We investigate perturbations of the Schwarzschild geometry using a linearization of the Einstein vacuum equations within a Bondi-Sachs, or null cone, formalism. We develop a numerical method to calculate the quasi-normal modes, and present results for the case $\ell=2$. The values obtained are different to those of a Schwarzschild black hole, and we interpret them as quasi-normal modes of a Schwarzschild white hole.

Zero-temperature Glauber dynamics on small-world networks

description: The zero-temperature Glauber dynamics of the ferromagnetic Ising model on small-world networks, rewired from a two-dimensional square lattice, has been studied by numerical simulations. For increasing disorder in finite networks, the nonequilibrium dynamics becomes faster, so that the ground state is found more likely. For any finite value of the rewiring probability p, the likelihood of reaching the ground state goes to zero in the thermodynamic limit, similarly to random networks. The spin correlation xi(r) is found to decrease with distance as xi(r) ~ exp(-r/lambda), lambda being a correlation length scaling with p as lambda ~ p^(-0.73). These results are compared with those obtained earlier for addition-type small world networks.

description: No abstracts are to be cited without prior reference to the author. Declines in black-legged kittiwake (Rissa tridactyla) populations in the UK have been linked to changing oceanographic conditions, with reduced food availability under higher temperatures leading to reduced productivity and survival. However, analyses have typically focused on relatively few intensively-studied colonies and have primarily considered sea surface temperature (SST), meaning that important drivers may have been overlooked. Here, we use data from tracking studies to produce colony-specific estimated foraging areas for eleven kittiwake colonies throughout the UK and Ireland, and examine the impacts of physical (SST, stratification strength, stratification onset) and biological (larval fish and copepod abundance) on kittiwake productivity. Higher productivity was associated with lower SSTs, and weaker, later stratification. Climate change projections indicated that rising SSTs could drive further productivity declines by the late 21st Century. Finally, higher kittiwake productivity associated with higher larval sandeel and Calanus finmarchicus abundance.
title: Estimation of aquaculture carrying capacity in Southeast Asia: needs and capabilities for modeling of common water bodies

Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author. With expansion of aquaculture in Southeast Asia, some water bodies have already exceeded their abilities to assimilate wastes from aquaculture production. The need to determine the maximum amount of aquaculture that can take place in a given water body is great. Resource managers first need to decide what they to protect (farmers, ecosystem, society), then calculate the appropriate carrying capacity (production, ecological or social). A variety of models can be used to predict the impacts of aquaculture wastes in the environment. Use of each depends on needs, available data, and user expertise. Ideally, such models are used before aquaculture production begins, so regulators only permit the appropriate amount of aquaculture and/or properly site the aquaculture operations. Most SE Asian countries have strategic plans that call for substantial increases in aquaculture production, but opinions on what to protect differ. Data available for models are usually sparse and scientists may need training to use more complex models. I recommend a phased approach to modeling of common water bodies, beginning with simple mass-balance models and progressing toward full ecosystem models over time. Because most countries permit aquaculture at the municipality level, an outreach program for municipal officials to prevent aquaculture overcapacity is needed
Enhanced coherent dynamics near a transition between neutral quantum-paraelectric and ionic ferroelectric phases in the quantum Blume-Emery-Griffiths model

description: Nonequilibrium dynamics are studied near the quantum phase transition point in the one-dimensional quantum Blume-Emery-Griffiths model. Its pseudo-spin component $ S^z $ represents an electric polarization, and $ (S^z)^2 $ corresponds to ionicity, in mixed-stack charge-transfer complexes that exhibit a transition between neutral quantum-paraelectric and ionic ferroelectric (or antiferroelectric) phases. The time-dependent Schrödinger equation is solved for the exact many-body wave function in the quantum paraelectric phase. After impact force is introduced on a polarization locally in space and time, polarizations and ionicity coherently oscillate. The oscillation amplitudes are large near the quantum phase transition point. The energy supplied by the impact flows linearly into these oscillations, so that the nonequilibrium behavior is uncooperative.
