description: We introduce a new class of effective interactions to be used within the energy-density-functional approaches. They are based on regularized zero-range interactions and constitute a consistent application of the effective-theory methodology to low-energy phenomena in nuclei. They allow for defining the order of expansion in terms of the order of derivatives acting on the finite-range potential. Numerical calculations show a rapid convergence of the expansion and independence of results of the regularization scale.

An exploration of inter-firm relationships in the Australian road freight transport industry

description: Organisations are increasingly looking beyond their organisational boundaries to evaluate how resources can be utilised to survive and grow the business. Different inter-organisational relationships have emerged as important resources in supply chains. The decision about what type of inter-firm relationship is appropriate for a specific circumstance appears complex and demands a particular degree of managerial attention. Supply chain researchers agree that in many instances, not all inter-firm relationships need to be either cooperative or collaborative and that there is no unique relationship suitable for all circumstances. While marketing channel theories and supply chain theories can provide some explanation for a wide range of inter-organisational relationships, the existing literature lacks a comprehensive explanation of the interplay between the attributes of relationships, the desired outcomes and differing inter-firm relationships. Consequently, this research seeks to fill the gap in the literature by first explaining the power that relational factors such as trust, power, interdependency, longevity and sharing, have in predicting the types of inter-firm relationships a firm participates in and, second, by understanding and discussing the linkages between achieved benefits, such as reduced costs, improved quality, flexibility, speed and reliability of an organisation involved in an array of relationships. In order to address the gap a theoretical framework was tested through a three stages methodology, which involved convergent interview, self-administered questionnaire and a case study. Qualitative data was analysed by using content analysis techniques in which patterns were identified from the data while quantitative data was analysed using confirmatory factor analysis and multiple regression analysis. The road freight transport industry was chosen as the research setting to examine inter-organisational relationships because of its complexity and competitiveness in the Australian setting. This thesis concludes that trucking firms are only marginally shifting from loose to closer relationships, so they tend primarily to be adversarial players and as such expect to achieve four primary outcomes. These are improvements in operational cost, flexibility, quality and reliability.-- Abstract

description: We calculate the bilinear combination of Dirac tensors describing the creation of a pair of charged particle (pi-meson or leptons) by virtual photons integrated on the final particle phase volume. It can be interpreted as an s channel discontinuity of the zero angle light-by-light scattering tensor with both photons off mass shell. The expression of light-by-light scattering tensor is represented in the form where the gauge invariance and the Bose symmetry are explicitly shown. Some applications and the checks are discussed.

In this paper we present various new results for these objects. Our results give light to unforeseen difficulties in the general solution to the problem, and they simplify some of the previous proofs.

subject: Early childhood education

description: The aim of this study was to investigate whether the introduction of dramatic storytelling could encourage children to engage in learning experiences that fostered ‘social imagination’. There is a substantial body of research that supports the benefits of drama and its capacity to deliver a range of outcomes identified in early childhood curriculum documents. Significant barriers for achieving such include, teacher’s general lack of confidence and experience around teaching drama, or beliefs about children’s play. The goal of this thesis was to better understand the phenomenon of teachers as co-constructors in the learning design and to reflect upon possible roles within children’s imaginative play experiences. Greene (1995) proposes that education should be the business of creating moral and compassionate humans, with the teacher’s role as the moral educator in co-constructing these experiences with the children. This presentation of children’s specific examples of empathy through the stories may provide new material for discussing the power of drama to achieve Greene’s educational goals. A qualatative case study approach was chosen for this research, presenting a dramatic storytelling experience which was trialled in a kindergarten classroom with the teacher involved as an insider/researcher, reflective practitioner. This study presents an example of practice that showcases a dramatic framework, drawing upon Dunn’s process drama and improvised text as well as Dorothy Heathcote’s ‘Mantle of the Expert’ to structure effective dramatic learning. Using a combination of both these works, five features were identified as useful to the learning design. These were then trialled and tested for their abilty to achieve learning outcomes for children linking to the Queensland Kindergarten Learning Guidelines (2010) in the particular areas of Wellbeing and Active Learning. These two key focus areas were chosen as they are most closely aligned to the focus of the study around ‘social imagination’ and empathy building. What was discovered through this research project was that the dramatic storytelling provided a frame for children’s agency and self-expression and was a powerful way to involve, engage and motivate children, also providing them with various degrees of autonomy in the process. It was also beneficial for some children who experienced social and learning issues, giving them multiple opportunities to engage in the dramtic episodes, practice empathy and cultivate ‘social imagination’.

description: Specialist Breast Care Nurses (SBCNs) provide essential support and treatment for women experiencing breast cancer and their families (Cruickshank, Kennedy, Lockhart, Dosser & Dallas, 2008; Liebert, Parle, White & Rodger, 2001; Rogers-Clark, 2002; Yates et al., 2007). The broad role of the SBCN is to coordinate care and provide ongoing psychological support to women with breast cancer and their families during diagnosis, treatment rehabilitation, follow-up and palliative care (Yates et al., 2007). This study addressed the gap in practice and research around support for SBCNs working in regional, rural and remote Queensland.

description: The formation of molecules and supramolecular structures results from bonding by conservative forces acting among electrons and nuclei and giving rise to equilibrium configurations defined by minima of the interaction potential. Here we show that bonding can also occur by the non-conservative forces responsible for interaction-induced coherent population trapping. The bound state arises in a dissipative process and manifests itself as a stationary state at a preordained interatomic distance. Remarkably, such a dissipative bonding is present even when the interactions among the atoms are purely repulsive. The dissipative bound states can be created and studied spectroscopically in present-day experiments with ultracold atoms or molecules and can potentially serve for cooling strongly interacting quantum gases.

description: Results are presented of a five-year project to study the orbital periods of eighteen deeply eclipsing novalike cataclysmic variables, collectively known as SW Sextantis stars, by combining new measurements of eclipse times with published measurements stretching back in some cases over fifty years. While the behaviour of many of these binary systems is consistent with a constant orbital period, it is evident that in several cases this is not true. Although the time span of these observations is relatively short, evidence is emerging that the orbital periods of some of these stars show cyclical variation with periods in the range 10-40 years. The two stars with the longest orbital periods, V363 Aur and BT Mon, also show secular period reduction with rates of -6.6 \times 10^{-8} days/year and -3.3 \times 10^{-8} days/year. New ephemerides are provided for all eighteen stars to facilitate observation of future eclipses.

description: We consider a microscopic model (a system of self-propelled particles) to study the behaviour of a large group of pedestrians walking in a corridor. Our point of interest is the effect of anisotropic interactions on the global behaviour of the crowd. The anisotropy we have in mind reflects the fact that people do not perceive (i.e. see, hear, feel or smell) their environment equally well in all directions. The dynamics of the individuals in our model follow from a system of Newton-like equations in the overdamped limit. The instantaneous velocity is modelled in such a way that it accounts for the angle under which an individual perceives another individual. We investigate the effects of this perception anisotropy by means of simulations, very much in the spirit of molecular dynamics. We define a number of characteristic quantifiers (including the polarization index and Morisita index) that serve as measures for e.g. organization and clustering, and we use these indices to investigate the influence of anisotropy on the global behaviour of the crowd. The goal of the paper is to investigate the potentiality of this model; extensive statistical analysis of simulation data, or reproducing any specific real-life situation are beyond its scope.

description: The bending energy of any freely deformable closed surface is quadratic in its curvature. In the absence of constraints, it will be minimized when the surface adopts the form of a round sphere. If the surface is confined within a hypersurface of smaller size, however, this spherical state becomes inaccessible. A framework is introduced to describe the equilibrium states of the confined surface. It is applied to a two-dimensional surface confined within a three-dimensional hypersphere of smaller radius. If the excess surface area is small, the equilibrium states are represented by harmonic deformations of a two-sphere: the ground state is described by a quadrupole; all higher multipoles are shown to be unstable.

description: We analyze the out-of-equilibrium behavior of exclusion processes where agents interact with their nearest neighbors, and we study the short-range correlations which develop because of the exclusion and other contact interactions. The form of interactions we focus on, including adhesion and contact-preserving interactions, is especially relevant for migration processes of living cells. We show the local agent density and nearest-neighbor two-point correlations resulting from simulations on two dimensional lattices in the transient regime where agents invade an initially empty space from a source and in the stationary regime between a source and a sink. We compare the results of simulations with the corresponding quantities derived from the master equation of the exclusion processes, and in both cases, we show that, during the invasion of space by agents, a wave of correlations travels with velocity v(t) ~ t^(-1/2). The relative placement of this wave to the agent density front and the time dependence of its height may be used to discriminate between different forms of contact interactions or to quantitatively estimate the intensity of interactions. We discuss, in the stationary density profile between a full and an empty reservoir of agents, the presence of a discontinuity close to the empty reservoir. Then, we develop a method for deriving approximate hydrodynamic limits of the processes. From the resulting systems of partial differential equations, we recover the self-similar behavior of the agent density and correlations during space invasion.
Low rank approximation for the numerical simulation of high dimensional Lindblad and Riccati equations

description: A systematic numerical approach to approximate high dimensional Lindblad equations is described. It is based on a deterministic rank m approximation of the density operator, the rank m being the only parameter to adjust. From a known initial value, this rank m approximation gives at each time-step an estimate of the largest m eigen-values with their eigen-vectors of the density operator. A numerical scheme is proposed. Its numerical efficiency in the case of a rank 12 approximation is demonstrated for oscillation revivals of 50 atoms interacting resonantly with a slightly damped coherent quantized field of 200 photons. The approach may be employed for other similar equations. We in particularly show how to adapt such low-rank approximation for Riccati differential equations appearing in Kalman filtering.

description: By adopting a new approach to the analysis of the density of p-adic solutions arising in applications of the circle method, we show that under modest conditions the existence of non-trivial p-adic solutions suffices to establish positivity of the singular series. This improves on earlier approaches due to Davenport, Schmidt and others, and allows us to establish an asymptotic formula for the number of simultaneous zeros of non-singular pairs of cubic forms in at least 131 variables. As a by-product, we obtain a version of Hensel's Lemma for linear spaces.

Deciding the Winner of an Arbitrary Finite Poset Game is PSPACE-Complete

description: A poset game is a two-player game played over a partially ordered set (poset) in which the players alternate choosing an element of the poset, removing it and all elements greater than it. The first player unable to select an element of the poset loses. Polynomial time algorithms exist for certain restricted classes of poset games, such as the game of Nim. However, until recently the complexity of arbitrary finite poset games was only known to exist somewhere between NC^1 and PSPACE. We resolve this discrepancy by showing that deciding the winner of an arbitrary finite poset game is PSPACE-complete. To this end, we give an explicit reduction from Node Kayles, a PSPACE-complete game in which players vie to chose an independent set in a graph.

Sing no sad songs: Grieving the death of a young adult child from cancer

Publisher: name: CQUniversity

subject: Other psychology not elsewhere classified

description: For bereaved parents the death of a child is the most tragic of all deaths. When a child dies, parents lose not only their child, but all their child represents, such as a future together and descendants. Life as they assumed it would be ends with the child’s death and the role of parent changes to that of bereaved parent. A child’s death seems to subvert the natural order. Parental grieving can be, therefore, the most devastating, the longest lasting, and the most far-reaching in its effects of all forms of grief. Although much has been written about grieving infant death, adolescent suicide and violent death, information is sparse on grieving the death of a young adult child from cancer. One of the reasons for this is that the incidence of cancer in the 18 to 25-year-old group is very rare. This thesis aims to address the gap with a creative nonfiction memoir titled Sing no sad songs and an exegesis titled Grieving the death of a young adult child from cancer. The creative work is a memoir of my own experience in dealing with the diagnosis, illness and death from cancer of my 23-year-old daughter, Rebecca. The exegesis consists of six chapters which provide a context for Sing no sad songs. Chapter one comprises a critical reflection on the inspiration and influences that informed my writing, the process I used, and issues that arose during the drafting. Chapter two contextualises Sing no sad songs within the findings of psychological and sociological theories of grief. Chapter three elaborates on these findings with an examination of spiritual perspectives on grief. Chapter four analyses the language traditionally used to describe grief and bereavement in Western societies. It concludes with an examination of the human affinity with story telling and the way in which narrative can be used as a tool to help the bereaved assimilate their grief into their changed life story. Chapter five is an analysis of creative nonfiction and examines my rationale for incorporating creative nonfiction techniques in my memoir. Chapter six concludes the exegesis. -- Abstract.
Clicking: A constructivist grounded theory for developing quantitative literacy for learning mathematics in an enabling course in tertiary education

description: Clicking is a theory that explains how students in this study developed quantitative literacy for learning mathematics in an enabling course at university. Using a grounded theory methodology, thirteen students from an enabling course at one institution were interviewed about what helped or hindered them in learning mathematics in a tertiary environment. Students who come to enabling courses often have had barriers and disruptions in prior learning experiences. While most come to enabling courses with the aim of improving their skills, progressing on to bachelor degrees and then professions, they often struggle in the formal learning environment. This is particularly so with mathematics with many students reporting that they do not like, or are not good at the subject. Despite the best intentions for this ‘second chance’ learning, numerous students continue to struggle, withdraw, or fail. This attrition is detrimental to students’ confidence, and also undesirable for the university. Even for those who remain, or are able to pass some assessment, they are still not confident in their ability to learn mathematics. Through this study, the concept of ‘clicking’ was found to be central to students’ understanding of the content, in particular, developing literacy practices that resonated with a literacy resource model for learning. Seven interrelated categories reported by the students were theorised through this model, with the key category of clicking emerging as a process for explaining how quantitative literacy was constructed by learners themselves. Clicking for quantitative literacy was constructed through a student learning cycle of relating, holding interest, exploring ways, taking time, practising, and working through confusion; with tailoring of ways of learning mathematics provided by teachers and others such as peers, family, friends. When used alongside adult learning principles, these findings offer a practical guide for teachers in enabling courses to use with their students to develop their knowledge of how to learn mathematics. For students, being quantitatively literate in ‘learning how to learn mathematics’ through clicking, has implications for success in mathematics learning in their chosen professional studies at university.

description: The validity of the assertion that some recent double-slit interference experiments, conducted by Radin et al., would have tested the possible role of the experimenter's mind in the collapse of the quantum wave function, is questioned. It is emphasized that quantum mechanics doesn't need any psychophysical ingredient to explain the measurement processes, and therefore parapsychologists shouldn't resort to the latter to support the possibility of psychokinesis, but search for more convincing explanations.

description: Pierre Auger experiment has observed a few cosmic ray events above 55 EeV from the direction of the core of Cen A. These cosmic rays might have originated from the core of Cen A. High energy gamma ray emission has been observed by HESS from the radio core and inner kpc jets of Cen A. We are testing whether pure hadronic interactions of protons or heavy nuclei with the matter in the core region or photo-disintegration of heavy nuclei can explain the cosmic ray and high energy gamma ray observations from the core of Cen A. The scenario of $p-γ$ interactions followed by photo-pion decay has been tested earlier by Sahu et al. (2012) and found to be consistent with the observational results. In this paper we have considered some other possibilities (i) the primary cosmic rays at the core of Cen A are protons and the high energy gamma rays are produced in $p-p$ interactions,(ii) the primary cosmic rays are Fe nuclei and the high energy gamma rays are produced in $Fe-p$ interactions and (iii) the primary cosmic rays are Fe nuclei and they are photo-disintegrated at the core. The daughter nuclei de-excite and high energy gamma rays are produced.

Using historical fiction to engage junior secondary students in the study of history: A case study
Creators: name: Rogers, Natasha
Publisher: name: CQUniversity
Year: 2023
Subjects: classificationCode: 390107
subject: Humanities and social sciences curriculum and pedagogy (excl. economics, business and management)

description: There is evidence in the literature that Junior Secondary students are becoming disengaged from school generally and, specifically, find History boring. In this respect, the recently implemented Australian Curriculum: History mandates the content and skills required to be taught in History but gives no pedagogical advice on how engagement can be fostered in the classroom. This research used a three-phase case study approach to an intervention - in the teaching of History to Year 8 students in a Queensland school, utilising historical fiction as a pedagogical tool for engagement. In Phase 1 of the research, a pre-unit survey was conducted to identity student attitudes to learning history. In Phase 2, an in-class intervention using historical fiction was designed and delivered. In Phase 3, the post-intervention focus group interviews were conducted to explore the impact of the use of historical fiction. The results from the research have identified four key insights into student perceptions of the use of historical fiction: • students made a connection between engagement in learning and entertainment; • students responded positively to reading historical fiction; • students thought historical fiction was an effective pedagogical approach to History for first-year high school students; and • students wanted autonomy in how they accessed the historical fiction. The findings from this research can be used by teachers and curriculum leaders as an example of a pedagogical strategy, using historical fiction as a way to affectively engage Junior Secondary students in the study of History.
Smectic order, pinning, and phase transition in a smectic liquid crystal cell with a random substrate

description: We study smectic-liquid-crystal order in a cell with a heterogeneous substrate imposing surface random positional and orientational pinnings. Proposing a minimal random elastic model, we demonstrate that, for a thick cell, the smectic state without a rubbed substrate is always unstable at long scales and, for weak random pinning, is replaced by a smectic glass state. We compute the statistics of the associated substrate-driven distortions and the characteristic smectic domain size on the heterogeneous substrate and in the bulk. We find that for weak disorder, the system exhibits a three-dimensional temperature-controlled phase transition between a weakly and strongly pinned smectic glass states akin to the Cardy-Ostlund phase transition. We explore experimental implications of the predicted phenomenology and suggest that it provides a plausible explanation for the experimental observations on polarized light microscopy and x-ray scattering.

In this contribution, after a brief introduction to the theoretical motivation for studying the large-N limit, the role of lattice computations in large-N gauge theories is discussed, and a selection of interesting results obtained in recent years is highlighted. Finally, some promising research directions for future studies are pointed out.

The branching fractions are measured to be $\mathcal{B}(ψ^\prime\to \bar{p}K^+Σ^0+c.c)= (1.67\pm0.13\pm0.12)\times10^{-5}$, $\mathcal{B}(χ_{c0}\to\bar{p}K^+Λ+c.c.)= (13.2\pm0.3\pm1.0)\times10^{-4}$, $\mathcal{B}(χ_{c1}\to\bar{p}K^+Λ+c.c.)= (4.5\pm0.2\pm0.4)\times10^{-4}$ and $\mathcal{B}(χ_{c2}\to\bar{p}K^+Λ+c.c)= (8.4\pm0.3\pm0.6)\times10^{-4}$, where the first error is statistical, and the second is systematic. In the decay of $χ_{c0} \to \bar{p}K^+Λ+ c.c.$, an anomalous enhancement near threshold is observed in the invariant mass distribution of $\bar{p}Λ+c.c.$, which cannot be explained by phase space.

description: The thermal relaxation time ($τ_{κ_{ee}}$) for the degenerate electron plasma has been calculated by incorporating non-Fermi liquid (NFL) corrections both for the thermal conductivity and specific heat capacity. Perturbative results are presented by making expansion in $T/m_D$ with next to leading order corrections (NLO). We see that the NLO NFL corrections further reduce the decrease in relaxation time due to the leading order (LO) correction.

description: We analyse the sensitivity of IceCube-DeepCore to annihilation of neutralino dark matter in the solar core, generated within a 25 parameter version of the minimally supersymmetric standard model (MSSM-25). We explore the 25-dimensional parameter space using scanning methods based on importance sampling and using DarkSUSY 5.0.6 to calculate observables. Our scans produced a database of 6.02 million parameter space points with neutralino dark matter consistent with the relic density implied by WMAP 7-year data, as well as with accelerator searches. We performed a model exclusion analysis upon these points using the expected capabilities of the IceCube-DeepCore Neutrino Telescope. We show that IceCube-DeepCore will be sensitive to a number of models that are not accessible to direct detection experiments such as SIMPLE, COUPP and XENON100, indirect detection using Fermi-LAT observations of dwarf spheroidal galaxies, nor to current LHC searches.

description: The Fermi Gamma-ray Space Telescope reveals two large bubbles in the Galaxy, which extend nearly symmetrically ~50 degrees above and below the Galactic center (GC). Using three-dimensional (3D) magnetohydrodynamic (MHD) simulations that self-consistently include the dynamical interaction between cosmic rays (CR) and thermal gas, and anisotropic CR diffusion along the magnetic field lines, we show that the key characteristics of the observed gamma-ray bubbles and the spatially-correlated X-ray features in ROSAT 1.5 keV map can be successfully reproduced by a recent jet activity from the central active galactic nucleus (AGN). We find that after taking into account the projection of the 3D bubbles onto the sky, the physical heights of the bubbles can be much smaller than previously thought, greatly reducing the formation time of the bubbles to about a Myr. This relatively small bubble age is needed to reconcile the simulations with the upper limit of bubbles ages estimated from the cooling time of high-energy electrons. No additional physical mechanisms are required to suppress large-scale hydrodynamic instabilities because the evolution time is too short for them to develop. The simulated CR bubbles are edge-brightened, which is consistent with the observed projected flat surface brightness distribution. Furthermore, we demonstrate that the sharp edges of the observed bubbles can be due to anisotropic CR diffusion along magnetic field lines that drape around the bubbles during their supersonic expansion, with suppressed perpendicular diffusion across the bubble surface. Possible causes of the slight bends of the Fermi bubbles to the west are also discussed.

description: We study the (local) Minkowski content and the (local) fractal Euler characteristic of limit sets $F\subset\mathbb R$ of conformal graph directed systems (cGDS) $Φ$. For the local quantities we prove that the logarithmic Cesàro averages always exist and are constant multiples of the $δ$-conformal measure. If $Φ$ is non-lattice, then also the non-average local quantities exist and coincide with their respective average versions. When the conformal contractions of $Φ$ are analytic, the local versions exist if and only if $Φ$ is non-lattice. For the non-local quantities the above results in particular imply that limit sets of Fuchsian groups of Schottky type are Minkowski measurable, proving a conjecture of Lapidus from 1993. Further, when the contractions of the cGDS are similarities, we obtain that the Minkowski content and the fractal Euler characteristic of $F$ exist if and only if $Φ$ is non-lattice, generalising earlier results by Falconer, Gatzouras, Lapidus and van Frankenhuijsen for non-degenerate self-similar subsets of $\mathbb R$ that satisfy the open set condition.

description: Trust is at the core of any payment method and its role is of vital importance in the adoption of a new payment system. Individuals need to trust in one another in order to validate any monetary system created. With the evolution of payment methods, shifting from paper-based to electronic-based, building consumer trust has become a vital element for the success of businesses involved in the mobile payment systems sector. In this sense, this research project aims to delve deeper into the effects of consumers trust on mobile payment systems (MPS) adoption in Australia. In order to collect data from Australian consumers, a quantitative approach through a secondary data analysis and questionnaire surveys were conducted in so far as this data can be measured and statistically analysed. Also, the data were gathered and imported into SPSS (Statistical Package for the Social Sciences) system, and after that, this research project adopted the partial least square structural equation modeling (PLS-SEM), where the data analysis took place. The results pointed out that trust is an essential factor for Australian consumers and it plays a pivotal role on MPS adoption. The results also revealed that Australian consumers have concerns about the security of their information and prefer using PIN or password to protect their data. In addition, they would adopt the MPS if they feel that organisations are providing a trustworthy service. The findings of PLS-SEM analysis pointed out that behavioural factors and organisational factors have significant impact on consumers’ trust, and this, as a consequence, have influence on MPS adoption. On the other hand, this research found that the technological factors, governmental factors and personal factors have no significant impact on Australian consumers’ trust and this, as a result, has no influence on MPS adoption.

description: We compute the chiral symmetries of the Lagrangian for confining "vector-like" gauge theories with massless fermions in $d$-dimensional Minkowski space and, under a few reasonable assumptions, determine the form of the quadratic fermion condensates which arise through spontaneous breaking of these symmetries. We find that for each type (complex, real, or pseudoreal) of representation of the gauge group carried by the fermions, the chiral symmetries of the Lagrangian, as well as the residual symmetries after dynamical breaking, exactly follow the pattern of Bott periodicity as the dimension changes. The consequences of this for the topological features of the low-energy effective theory are considered.

Forbidden oxygen lines in comets at various heliocentric distances

description: We present a study of the three forbidden oxygen lines [OI] located in the optical region (i.e., 5577.339 Å (the green line), 6300.304 Å and 6363.776 Å (the two red lines)) in order to better understand the production of these atoms in cometary atmospheres. The analysis is based on 48 high-resolution and high signal-to-noise spectra collected with UVES at the ESO VLT between 2003 and 2011 referring to 12 comets of different origins observed at various heliocentric distances. The flux ratio of the green line to the sum of the two red lines is evaluated to determine the parent species of the oxygen atoms by comparison with theoretical models. This analysis confirms that, at about 1 AU, H2O is the main parent molecule producing oxygen atoms. At heliocentric distances > 2.5 AU, this ratio is changing rapidly, an indication that other molecules are starting to contribute. CO and CO2, the most abundant species after H2O in the coma, are good candidates and the ratio is used to estimate their abundances. We found that the CO2 abundance relative to H2O in comet C/2001 Q4 (NEAT) observed at 4 AU can be as high as ~70 %. The intrinsic widths of the oxygen lines were also measured. The green line is on average about 1 km/s broader than the red lines while the theory predicts the red lines to be broader. This might be due to the nature of the excitation source and/or a contribution of CO2 as parent molecule of the 5577.339 Å line. At 4 AU, we found that the width of the green and red lines in comet C/2001 Q4 are the same which could be explained if CO2 becomes the main contributor for the three [OI] lines at high heliocentric distances.
