An investigation of adult learning of mathematics
Creators: name: de Little, Catherine
Publisher: name: University Of Tasmania
Year: 2023

description: This case study investigated some of the factors facilitating the learning of mathematics by adult students. In particular, the research looked into the use of visualising strategies related to work place experiences, and real-world referents, to facilitate the understanding and use of algebraic variables, and algebraic notation and conventions. The subjects were six male and two female students, chosen from the engineering and science students at the Burnie campus of the North West Coast Regional College of TAFE. They were mature age students, with reasonable work experience, and all had finished school-based study of mathematics in Grade 10. Four of them had a trade background, and four had had no formal training since leaving school. Background factors were investigated with a written questionnaire, followed by an interview. Basic mathematical competence was measured using the ACER Mathematics Profile Series Operations Test, direct visualising ability was measured with Betts Questionnaire on Mental Imagery, and spatial ability was measured with the ACER Mathematics Profile Series Space Test Unit IV. A twenty item algebra test investigated the students' meanings and use of algebraic letters, and their facility with algebraic notation and conventions. Following error analysis, the subjects were interviewed to obtain insights into their cognitive processes, particularly where errors had occurred. Results of analysis of the first three test instruments revealed high levels of mathematical competence for these students, but no correlation between the two tests of visual and spatial abilities. The TAFE students' results on the algebra test were consistently higher than results recorded for similar research with a wide range of students in both England and Australia. Evidence from interviews suggested that the TAFE stadents' greater facility with algebraic concepts could be related to their experience of mathematics with real-world referents, both in the workplace and in exposure to applied mathematics in other subjects. Less able students appeared inhibited in moving beyond a concrete base to more abstract relationships, but the able students successfully transcended their real-world referents and were able to interpret and manipulate variables logically and consistently.

description: No abstracts are to be cited without prior reference to the author. Linking watershed and offshore ecosystems through data and models, the decision support system Baltic Nest is a natural platform for including environmental, ecological, and societal knowledge in stock and ecosystem assessments. Because a coupling of even simplified representations into holistic description can by itself reveal the emergent properties, the most important is a choice of those conditions and interactions that determine the problem in question. In a suggested development, the simplified ecosystem models are used to simulate the environment, including pelagic and benthic “food” for fish, for the Simple As Necessary Fish model. Being driven by outputs from these models, SANFish plausibly reproduces levels of major fish stanza’s biomass, production, and trophic interactions determined by the combined effects of fishery and eutrophication.

description: We study QCD thermodynamics in presence of two independent imaginary chemical potentials coupled to two degenerate flavors of staggered quarks. Analytic continuation is used to determine non-linear susceptibilities, to test the Hadron Resonance Gas (HRG) model below the zero density critical temperature, Tc, and to determine the average phase factor of the fermion determinant. Deviations from HRG predictions, of the order of a few percent, are clearly visible for temperatures T > 0.95 Tc. The determination of non-linear susceptibilities, using different interpolating functions for analytic continuation, gives consistent results and in agreement with Taylor expansion computations, apart from some systematic effects at or right above Tc. Results for the average phase factor are compared with the predictions of Chiral Perturbation Theory; below Tc we are able to distinguish the contribution of different hadron states, which is positive (i.e. tends to mitigate the sign problem) in the case of baryons.

description: The present work examines how judgments of others’ commitment to a goal are influenced by three factors that influence one’s own goal commitment (satisfaction, investment, and alternatives). In two studies these three factors were manipulated. The results indicated that people rate another’s goal commitment higher when goal satisfaction is high, goal investment is high and goal alternatives are low. It was also found that satisfaction and investments alter perceptions of the other’s abilities, and that this relationship is partially mediated by perceived goal commitment. The present studies offer novel findings that highlight the information we use to judge the goal commitment of others and the consequences that are incurred when these judgments are formed.

description: The photometric, structural and kinematical properties of the centers of elliptical galaxies, harbor important information of the formation history of the galaxies. In the case of non active elliptical galaxies these properties are linked in a way that surface brightness, break radius and velocity dispersion of the core lie on a fundamental plane similar to that found for their global properties. We construct the Core Fundamental Plane (CFP) for a sizeable sample of low redshift radio galaxies and compare it with that of non radio ellipticals. To pursue this aim we combine data obtained from high resolution HST images with medium resolution optical spectroscopy to derive the photometric and kinematic properties of ~40 low redshift radio galaxies. We find that the CFPs of radio galaxies is indistinguishable from that defined by non radio elliptical galaxies of similar luminosity. The characteristics of the CFP of radio galaxies are also consistent (same slope) with those of the Fundamental Plane (FP) derived from the global properties of radio (and non radio) elliptical galaxies. The similarity of CFP and FP for radio and non radio ellipticals suggests that the active phase of these galaxies has minimal effects for the structure of the galaxies.

description: Recent social movements have illuminated systemic inequities in U.S. society, including within the social sciences. Thus, it is essential that attachment researchers and practitioners engage in reflection and action to work toward anti-racist perspectives in the field. Our aims in this paper are (1) to share the generative conversations and debates that arose in preparing the Special Issue of Attachment & Human Development, “Attachment Perspectives on Race, Prejudice, and Anti-Racism”; and (2) to propose key considerations for working toward anti-racist perspectives in the field of attachment. We provide recommendations for enriching attachment theory (e.g. considering relations between caregivers’ racial-ethnic socialization and secure base provision), research (e.g. increasing the representation of African American researchers and participants), and practice (e.g. advocating for policies that reduce systemic inequities in family supports). Finally, we suggest two relevant models integrating attachment theory with perspectives from Black youth development as guides for future research.

description: Astrometry can bring powerful constraints to bear on a variety of scientific questions about neutron stars, including their origins, astrophysics, evolution, and environments. Using phase-referenced observations at the VLBA, in conjunction with pulsar gating and in-beam calibration, we have measured the parallaxes and proper motions for 14 pulsars. The smallest measured parallax in our sample is 0.13+-0.02 mas for PSR B1541+09, which has a most probable distance of 7.2+1.3-1.1 kpc. We detail our methods, including initial VLA surveys to select candidates and find in-beam calibrators, VLBA phase-referencing, pulsar gating, calibration, and data reduction. The use of the bootstrap method to estimate astrometric uncertainties in the presence of unmodeled systematic errors is also described. Based on our new model-independent estimates for distance and transverse velocity, we investigate the kinematics and birth sites of the pulsars and revisit models of the Galactic electron density distribution. We find that young pulsars are moving away from the Galactic plane, as expected, and that age estimates from kinematics and pulsar spindown are generally in agreement, with certain notable exceptions. Given its present trajectory, the pulsar B2045-16 was plausibly born in the open cluster NGC 6604. For several high-latitude pulsars, the NE2001 electron density model underestimates the parallax distances by a factor of two, while in others the estimates agree with or are larger than the parallax distances, suggesting that the interstellar medium is irregular on relevant length scales. The VLBA astrometric results for the recycled pulsar J1713+0747 are consistent with two independent estimates from pulse timing, enabling a consistency check between the different reference frames.

Alteration as a vector to copper mineralisation in the Royal Tharsis deposit, Mount Lyell mineral field
Creators: name: Godsall, William J. D
Publisher: name: University Of Tasmania
Year: 2023

description: Royal Tharsis was mined as an underground operation and as part of the West Lyell Open Cut. The original orebody consisted of steep south-westerly dipping echelon lenses striking 315¬¨‚àû and extending to a depth of some 600 metres. The topographical expression would have been steep slopes of CVC alteration assemblages dominated by the Tharsis Ridge, a buttress of Owen Group rock types that separates West Lyell from North Lyell. Sulphide mineralisation is dominantly pyrite and for which at least one generation has been identified, with subordinate chalcopyrite. Bomite, chalcocite-digenite, covellite, molybdenite, sphalerite and galena have also been identified. Volcanic precursors include rhyolitic and dacitic volcanics, volcaniclastics (locally autobrecciated), brecciated lavas and minor porphyries. Intense and selective alteration has resulted in obliteration of primary textures. Feldspar destruction is almost ubiquitous. Rare albitised plagioclase occurs towards the periphery of the alteration system. Broad correlation exists between sulphide mineralisation and alteration patterns. Ten main alteration assemblages have been identified: mixed mica, quartz-mixed mica, quartz-sericite, quartz-pyrite, quartz-chlorite¬¨¬±sericite, chlorite, meta-conglomerate, quartz-haematite, quartz-magnetite and magnetite-apatite. The most common alteration assemblages include: quartz-sericite; quartz-chlorite-sericite and/or quartzsericite-chlorite; and chlorite or quartz-chlorite assemblages. The Ishikawa alteration index increases up stratigraphy and shows a subtle change through the ore zone. The chlorite-pyrite-carbonate alteration index shows a change in gradient through the ore zone relative to hangingwall lithologies. The manganesecarbonate alteration index shows a relative drop at the stratigraphic footwall of copper mineralisation, but otherwise portrays a poorly defined response. The Ti/Zr value falls in the dacite - rhyolite range, with occasional andesite values. Sulphide (pyrite) and carbonate show an almost inverse relationship, with a weak zonation evident between Fe-S-C-¬¨¬±0. Carbonate alteration through the mineralisation is muted and variable, and where distal is probably due to remobilisation rather than primary. K20 shows a subtle response to mineralisation and thus may be a subtle vector to ore. Na20 depletion occurs through the ore halo and into the hangingwall. Barium and Ba/Sr ratio show enrichment through the mineralised halo, identified by a Ba/Sr value that rises above 30. REE show uniform elevated responses through the mineralised halo. Gold, silver, molybdenum, cobalt and ¬¨¬± nickel all correlate reasonably well with copper. Fe2O3 and P2O5 both correlate with copper, indicative of pyrite and apatite relationships respectively, the latter pointing to the influence of magmatic hydrothermal fluids. The abundance of illite is suggestive of the presence of weakly acidic (CO2 -rich) fluids.
Perturbation theory in a pure exchange non-equilibrium economy

description: We develop a formalism to study linearized perturbations around the equilibria of a pure exchange economy. With the use of mean field theory techniques, we derive equations for the flow of products in an economy driven by heterogeneous preferences and probabilistic interaction between agents. We are able to show that if the economic agents have static preferences, which are also homogeneous in any of the steady states, the final wealth distribution is independent of the dynamics of the non-equilibrium theory. In particular, it is completely determined in terms of the initial conditions, and it is independent of the probability, and the network of interaction between agents. We show that the main effect of the network is to determine the relaxation time via the usual eigenvalue gap as in random walks on graphs.

Meaning in life among adolescent leaders, non-leaders, and deviants
Creators: name: Piquette, Edmond Andre Albert
Publisher: name: University of British Columbia
Year: 2011

description: This study compares meaning in life scores of leader, non-leader, and deviant adolescents. Two thousand nine hundred and forty-nine secondary school students took the Purpose In Life Test. The students were divided into groups according to their behavior, their level of academic achievement, their sex, and grade level. Results: The leader group had the highest meaning in life score, the non-leader group had the second highest meaning in life score, and the deviant group had the lowest meaning in life score. The higher achieving group did not have higher meaning in life score than did the lower achieving group. Male and female students did not have significantly different meaning in life scores. Grade eight and nine students had higher meaning in life scores than did grade ten, eleven, and twelve students. These findings provide empirical evidence in support of several inferences based on Frankl's theory of meaning in life. First, a higher level of social and athletic involvement is associated with high meaning in life and a sense of usefulness and identity. Secondly, existential vacuum underlies deviant behavior of students who isolate themselves by violating the rules and sanctions of the school. Thirdly, academic success or subject matter mastery was not related to high meaning in life. Fourthly, questioning the meaning of life is most apt to occur during the later stages of adolescent development, namely, during grades ten, eleven, and twelve. Replication of this study would determine whether or not these findings and inferences are true of adolescents in general.

description: In neutral graphene dots the Fermi level coincides with the Dirac points. We have investigated in the presence of a magnetic field several unusual properties of single electron states near the Fermi level of such a rectangular-shaped graphene dot with two zigzag and two armchair edges. We find that a quasi-degenerate level forms near zero energy and the number of states in this level can be tuned by the magnetic field. The wavefunctions of states in this level are all peaked on the zigzag edges with or without some weight inside the dot. Some of these states are magnetic field-independent surface states while the others are field-dependent. We have found a scaling result from which the number of magnetic field-dependent states of large dots can be inferred from those of smaller dots.

For $\ell =4$, $L_{D_{4}}(-{5/2},0)$ is a vertex subalgebra of three copies of $L_{B_{4}}(-{5/2},0)$ contained in $L_{F_{4}}(-{5/2},0)$, and all five of these vertex operator algebras have the same conformal vector.

description: The Gerasimov-Drell-Hearn sum rule and related dispersive integrals connect real and virtual Compton scattering to inclusive photo- and electroproduction. Being based on universal principles as causality, unitarity, and gauge invariance, these relations provide a unique testing ground to study the internal degrees of freedom that hold a system together. The present contribution reviews the spin-dependent sum rules and cross sections of the nucleon. At small momentum transfer, the data sample information on the long range phenomena (Goldstone bosons and collective resonances), whereas the primary degrees of freedom (quarks and gluons) become visible at large momentum transfer (short distance). The rich body of new data covers a wide range of phenomena from coherent to incoherent processes, and from the generalized spin polarizabilities on the low-energy side to higher twist effects in deep inelastic scattering.

description: We examine various direct and indirect experimental constraints on the nearly minimal supersymmetric standard model (nMSSM) and obtain the following observations: (i) Current experiments stringently constrain the parameter space, setting a range of 1-37 GeV for the lightest neutralino (LSP), 30-140 GeV (1-250 GeV) for the lightest CP-even (CP-odd) Higgs boson, and 1.5-10 for \tanβ; (ii) To account for the dark matter relic density, besides the s-channel exchange of a Z-boson, the s-channel exchange of a light A_1 (the lightest CP-odd Higgs boson) can also play an important role in LSP annihilation. Compared with the Z-exchange annihilation channel, the A_1 exchange channel is more favored by muon g-2 data and allows much broader regions for the parameters; (iii) In a large part of the allowed parameter space the SM-like Higgs boson may dominantly decay to LSP pair or A_1 pair and the conventional visible decays (e.g. into bottom quarks) are severely suppressed.

description: No abstracts are to be cited without prior reference to the author. The sustainable conservation and exploitation of the fisheries resources has become an explicit purpose in Europe through the reformed Common Fisheries Policy (CFP). The Ecosystem Approach for Fisheries Management (EAFM) aims to achieve this ambitious goal, balancing heterogeneous objectives and ensuring the sustainability at long-term. Nevertheless, the quantification of its consequences on society is one of the main challenges for implementing this approach. In this paper a methodology for evaluating the socio-economic effects of the EAFM in Galicia (NW Spain) is proposed. In particular, several alternatives of stock advises (e.g. MSY, MEY, MMSY) are analysed in terms of income and employment. Therefore, these advises are translated, through the input-output tables, into direct and indirect socio-economics' impacts in one of the most important European fishing regions. Finally, different management scenarios are proposed to support the decision-making of public authorities.

description: No abstracts are to be cited without prior reference to the author. This paper describes and compares experiences from fisheries co-management at different levels ranging from local to regional/ trans-national examples. We analyse these co-management experiences in terms of the information provided, the interaction between different knowledge types and their integration into policy- and decision-making. At the local level we investigate co-management experiences in Sweden whereas on a regional level we focus on experiences from the Baltic Sea and its EU Advisory Council. The analyses highlight how different methods for stakeholder participation and knowledge integration need to be adapted in order to meet the requirements for a legitimate, authoritative and accountable knowledge-base to implement policy and management decisions

A review of the treatment components and effectiveness of EMDR in PTSD
Creators: name: Fraser, Jilli Maree
Publisher: name: University Of Tasmania
Year: 2023

description: Post Traumatic Stress Disorder (PTSD) is treated psychologically with exposure and cognitive restructuring techniques. Shapiro's (1995) Eye Movement Desensitisation and Reprocessing (EMDR) treatment for PTSD involves imaginal exposure, cognitive restructuring, and rapid eye movements (EMs). EMDR has been presented as an advance in the treatment of PTSD, based on the theory that rapid EMs facilitate the accelerated processing of trauma-related information, via the activation of physiological mechanisms which stimulate retrieval of positive memories and emotions (Shapiro, 1995). It is suggested in this literature review that Shapiro's EMs theories are unsound, and that claims that EMDR is superior to traditional PTSD treatments are premature, but it is proposed that EMDR may have therapeutic benefits in treating PTSD. It is suggested that the exposure and cognitive restructuring components of EMDR may be more critical than the EMs in reducing PTSD symptoms. However, the EMs may facilitate client acceptance of these components by distracting clients from their anxiety and reducing the intensity of imaginal exposure. Alternative theories of the role of eye movements in EMDR need to be investigated in future research.

description: Collagen is the most abundant extracellular-network-forming protein in animal biology and is important in both natural and artificial tissues, where it serves as a material of great mechanical versatility. This versatility arises from its almost unique ability to remodel under applied loads into anisotropic and inhomogeneous structures. To explore the origins of this property, we develop a set of analysis tools and a novel experimental setup that probes the mechanical response of fibrous networks in a geometry that mimics a typical deformation profile imposed by cells in vivo. We observe strong fiber alignment and densification as a function of applied strain for both uncrosslinked and crosslinked collagenous networks. This alignment is found to be irreversibly imprinted in uncrosslinked collagen networks, suggesting a simple mechanism for tissue organization at the microscale. However, crosslinked networks display similar fiber alignment and the same geometrical properties as uncrosslinked gels, but with full reversibility. Plasticity is therefore not required to align fibers. On the contrary, our data show that this effect is part of the fundamental non-linear properties of fibrous biological networks.

Such curves are often called Devaney hairs. We show that, in many cases, every point in such a curve, apart from possibly a finite endpoint of the curve, belongs to the fast escaping set. We also give an example of a Devaney hair which lies in a logarithmic tract of a transcendental entire function and contains no fast escaping points.

description: We calculate the $3s$- and $4s$-core-level x-ray photoemission spectroscopy (XPS) spectra in the ferromagnetic and nonmagnetic transition metals by developing an \emph{ab initio} method. We obtain the spectra exhibiting the characteristic shapes as a function of binding energy in good agreement with experimental observations. The spectral shapes are strikingly different between the majority spin channel and the minority spin channel for ferromagnetic metals Ni, Co, and Fe, that is, large intensities appear in the higher binding energy side of the main peak (satellite) in the majority spin channel. Such satellite or shoulder intensities are also obtained for nonmagnetic metals V and Ru. These behaviors are elucidated in terms of the change of the one-electron states induced by the core-hole potential.

Immune response of Barramundi (Lates calcarifer) to Vibrio harveyi bacterin
Creators: name: Crosbie, Philip
Publisher: name: University Of Tasmania
Year: 2023

description: Commercial farming of barramundi or Asian seabass (Lates calcanfer) is a burgeoning industry in Australia and South East Asia. At present there are few serious bacterial infections, however disease caused by Vibrio harveyi infection is an on-going problem with the potential to become chronic as the industry expands. Therefore, the development of an effective vaccine against vibriosis was seen as a prudent strategy for the future success of barramundi production. This thesis reports on the development of appropriate reagents for in vitro monitoring of immune responses to a bacterin, and subsequent validation in laboratory trials where fish were immunised with a bacterin via various routes or, with lipopolysaccharide (LPS) via intraperitoneal (IP) injection. Barramundi immunoglobulin was isolated by affinity chromatography using either mannanbinding protein (MBP) or Staphylococcal protein A (SpA) as capture ligands. Both isolation products were used to produce polyclonal antisera in rabbits, which were subsequently compared for specificity and titer. Two antisera were used to monitor anti-V. harveyi antibody activity in barramundi serum after primary and secondary immunisations with bacterin via the IP route. Elevated antibody levels after secondary immunisation indicated a memory response. The routes of bacterin administration were investigated in terms of antibody production and some non-specific immune parameters. It was found that barramundi respond systemically to bacterin delivered by IP injection, immersion (IMIM) and anal intubation (Al). The highest and most consistent response was in fish treated via IP followed by AT then IMM. This consistency of response from IP-treated fish carried over to bacterial inhibitory activity of serum where all demonstrated >50% inhibitory activity relative to non-immune controls. There was no significant enhancement of serum lysozyme activity nor head kidney macrophage phagocytic activity as a result of any immunisation procedure. Finally, the response of barramundi to IP immunisation with bacterin or lipopolysaccharide (LPS) extracted from the bacterium was compared to elucidate the role of the latter. There were systemic antibody responses to both preparations with little difference noted in the magnitude of the response. However, bacterial inhibitory activity of serum was highest in the bacterin treament group. This may indicate that anti-LPS antibodies do not agglutinate to the same extent as anti-whole bacterial cell antibodies. In conclusion, systemic antibody and bacterial inhibitory activity after immunisations with the bacterin suggests that it may be an effective vaccine and oral administration is worth investigation. The protective role of LPS is unclear, though relatively lower bacterial inhibitory activity of anti-LPS antibodies suggests it may be less protective than anti-whole bacterial cell antibodies.

description: No abstracts are to be cited without prior reference to the author. The diversity of species targeted by Spanish otter trawl fleet results it in limitation for the fisheries management in the Galician-Cantabrian Sea fishing ground. The effort pressure of this fleet is shared in two main métiers, a demersal métier targeting hake, megrims and anglerfish and pelagic métier targeting horse mackerel and mackerel. A descriptive analysis of the fleet dynamics in terms of landings volume and economic value was carried out across the period 2007-2012. A discrete model choice framework was used to identify factors involved in fisher decision-making to select a métier. The approach was applied using a binomial logit model to data from 2007 to 2010. Economic variables, management measures and previous experience of each vessel were considered as potential explanatory variables. Our results indicate that the tradition and the past experience are the most important factors to make decisions about a future métier. The anglerfish price had a positive effect on the probability of demersal métier.

description: Amoebic gill disease (AGD), caused by Paramoeba sp., is the most serious infectious disease infecting sea caged Atlantic salmon, Salmo salar L., in Tasmania, Australia. After AGD had been described from Tasmanian salmonids, it also emerged as a problem in other countries. Major outbreaks have occurred in France, Spain and Ireland and disease, although not to the same extent, has been reported in the US and New Zealand. In Tasmania at present, treatment consists of a series of freshwater baths given during the critical high temperature, high salinity periods of the year. These baths last between two to three hours and during a normal summer fish are usually treated two to three times. However, there have been summers when up to eight baths have been undertaken and it appears recently, that this scenario is becoming more common. Because of the time and monetary costs associated with AGD, the Tasmanian industry is constrained with regards to increasing production and thus it's competitiveness in international and domestic markets. Any strategy that would eliminate or even reduce the number of baths required would be of substantial commercial value. All attempts to find a practical chemotherapeutic agent have been fruitless, thus immunisation and/or immunostimulation appeared to offer the best hope of providing an alternative treatment strategy. This project reports for the first time, the presence of varying degrees of resistance to AGD in fish that have been previously infected and then treated using freshwater bathing and demonstrates that this resistance can be modulated via the use of the immunostimulant, levamisole. It is also the first report of the use and efficacy of levamisole as an immunostimulant of the nonspecific defence system of Atlantic salmon. In order to achieve the results obtained a number of novel and improved experimental techniques were developed and are reported here.
title: Oil price shocks and macroeconomic policy in resource-rich emerging economies

description: This thesis is a collection of three papers aimed at investigating the macroeconomic effects of oil price shocks on resource-rich economies as well as the appropriate policy responses for ameliorating such effects. The first paper begins by examining the implications of physical capital and oil intensity of domestic production for the response of a small open economy to an oil price shock. Building on the work by Ferrero and Seneca (JMCB 2019), we find that the introduction of physical capital amplifies the responses of output and inflation to oil price shocks whereas the effects are attenuated by the oil intensity in domestic production. Also, our results reveal that the added features are important for the response of monetary policy to an oil price shock. Under our model set up, the optimal monetary policy response requires that the central bank keeps an eye not only on output and inflation, but also the exchange rate. These results highlight the need for cautious interpretation of the quantitative impacts of an oil price shock generated based on New Keynesian models of oil producing economies that abstract from capital. Paper 2 studies the role of oil price shocks in driving business cycle fluctuations of an oil-producing emerging economy with an inefficient fuel subsidy regime. Results from our estimated DSGE model for the Nigerian economy show that output fluctuations are driven mainly by oil and monetary policy shocks in the short run. However, oil shocks play a less prominent role in driving inflation dynamics owing partly to the low pass-through effect of international oil price into domestic prices implied by the fuel subsidy regime. While we find the core inflation-based Taylor rule optimal, we demonstrate that the Central Bank of Nigeria (CBN) faces a dilemma of either stabilising output or inflation in the face of an adverse oil price shock. Simulation results show that an “across-the-board” monetary policy strategy does not exist for dealing with an oil price shock in the resource-rich economy; thus, it is important that the CBN is aware of the observed trade-offs. The last paper investigates monetary-fiscal interactions in a resource-rich emerging economy whose fiscal policy is largely driven by resource-related flows. To achieve this, we analyse Nigeria’s experience over the last two decades by developing and estimating a suitable DSGE model. Our results provide convincing evidence of an active monetary and passive fiscal policy over the full sample. Furthermore, we confirm the presence of revenue substitution; a phenomenon that alters the "automatic stabilisers" role of fiscal policy in the resource-rich economy. The 2008/09 global financial crisis did not significantly alter these findings. However, our results are sensitive to (i) the response of fiscal policy to resource-related flows and (ii) the response of monetary policy to exchange rate.
Black Holes in Pseudobulges and Spheroidals: A Change in the Black Hole-Bulge Scaling Relations at Low Mass

description: We investigate the relationship between black hole mass and host galaxy properties for active galaxies with the lowest black hole masses currently known in galaxy nuclei. Hubble Space Telescope imaging confirms that the host galaxies have correspondingly low luminosity; they are ~1 mag below L*. In terms of morphology, ~60% of the members of the sample are disk-dominated, and all of these are consistent with containing a bulge or (more likely) pseudobulge, while the remainder are compact systems with no discernible disk component. In general the compact components of the galaxies do not obey the fundamental plane of giant elliptical galaxies and classical bulges, but rather are less centrally concentrated at a given luminosity, much like spheroidal galaxies. Our results strongly confirm that a classical bulge is not a requirement for a nuclear black hole. At the same time, the observed ratio of black hole to bulge mass is nearly an order of magnitude lower in this sample than that seen for classical bulges. While the M-sigma relation appears to continue to low mass, it seems that black hole-galaxy scaling relations do depend on galaxy structure.

Traction control using artificial neural networks
Creators: name: Butler, DA
Publisher: name: University Of Tasmania
Year: 2023

description: Modern traction control techniques manage driven wheel speed from data obtained through a small number of sensors from around an automobile. This data is then fed into an on-board computer that has been specially programmed to attempt to maximise driven wheel traction from its information base. Problems can arise, however, when abnormal conditions are encountered. The small number of sensors used as controller inputs and the various assumptions made during the conventional controller programming can lead to erroneous correction commands ‚ÄövÑvÆ with an increased risk of spinout and other undesirable situations. The incorporation of artificial neural networks into the traction controller command logic has the scope to bring a two-fold advantage. The first stems from a neural network's ability to learn. It can be programmed through experimental data, and thus removes the need for tedious mathematics programming of the vehicle dynamics, which can be used to reduce controller cost and also brings about the possibility of continual reprogramming as the vehicle's condition alters due to wear, etc. The second is its ability to cope with data from a large number of sensors. With more sensors in place, the NN has a large base of information on which to make decisions on how to optimise traction. The result, hopefully, will be a traction control response that will provide superior traction solutions and be readily programmed to suit different applications. This study aims at conducting preliminary research into the accuracy and application limitations of artificial neural networks in the interests of determining their feasibility for use in closed loop traction control applications. This includes selecting parameters to be predicted, as well as model input variables, network architectures and the collection of network training data for off-line control. To this end the accuracy of back-propagation and general regression neural networks will be compared using 14 input, single output architectures in the interests of predicting longitudinal acceleration, lateral acceleration and yaw angle, which are identified as crucial factors in vehicle dynamics control. The study also includes the complete construction of a test vehicle, in which the sensors are mounted and data acquisition systems used to gather the network training and testing data, from which this investigation is based. This work is a step towards establishing the applications of artificial neural networks to automobile applications on a sound mathematical and quantitative basis.

description: No abstracts are to be cited without prior reference to the author. The current harvest control rule (HCR) for Northeast Arctic cod depends on point estimates of the size of the spawning stock biomass (SSB) and fishing mortality (F). We make a case for an alternative formulation of the HCR that uses confidence intervals that accurately describe the underlying data.

description: Variational and diffusion quantum Monte Carlo (VMC and DMC) calculations of the properties of the zero-temperature fermionic gas at unitarity are reported. The ratio of the energy of the interacting to the non-interacting gas for a system of 128 particles is calculated to be 0.4517(3) in VMC and 0.4339(1) in the more accurate DMC method. The spherically-averaged pair-correlation functions, momentum densities, and one-body density matrices are very similar in VMC and DMC, but the two-body density matrices and condensate fractions show some differences. Our best estimate of the condensate fraction of 0.51 is a little smaller than values from other quantum Monte Carlo calculations.
