description: The issue of Educational Philosophy influences the direction of the entire education. It defines the educational process, the content, its methods and techniques as well as the interaction in the classroom. The purpose of this study is to investigate the Educational Philosophy of future teachers of all the Schools of the Faculty of Philosophy (School of Philosophy and Education, School of Philology, School of History and Archaeology) analyzing their knowledge and beliefs, to explore whether they are affected by the basic schools of thought and to understand the consequences of this influence in their educational practice. The connection of their beliefs with the basic schools of thought, that of Idealism, Realism, Pragmatism, of Existentialism and Reconstructionism, provides an overview of how the future education will be. The theoretical part defines the framework of Educational Philosophy with reference to its key components such as the philosophy of each individual’s life and the area of Philosophy and the basic educational philosophies. The research part includes the application of the questionnaire of Philosophy of Adult Education Inventory (PAEI) and some interviews. In the last part, takes place the analysis of students’ results. Thus becomes apparent how someone is guided in shaping his educational identity.

In particular, we investigate the possible shapes of their mass-energy density and find that they can be multi-peaked, we give numerical evidence and a partial proof for the conjecture that the Buchdahl inequality $\sup_{r > 0} 2 m(r)/r < 8/9$, $m(r)$ the quasi-local mass, holds for all such steady states--both isotropic {\em and} anisotropic--, and we give numerical evidence and a partial proof for the conjecture that for any given microscopic equation of state--both isotropic {\em and} anisotropic--the resulting one-parameter family of static solutions generates a spiral in the radius-mass diagram.

description: Background

Post-traumatic pneumatocele is a rare entity, presenting a case report will help better understanding of these types of injuries. Patients can be asymptomatic or have respiratory distress, hemoptysis, etc. Diagnosis is based on the history of blunt thoracic trauma, CT scans that suggest pneumatocele, and blood tests that rule out infectious processes. It is generally a self-limiting benign condition for up to a period of 6 months, in case of complications they may require surgery. Follow-up of discharged patients is necessary to identify complications because it can be life threatening.

Studies of the orientational order and bilayer thickness in biological and model membranes
Creators: name: Monck, Myrna A.
Publisher: name: University of British Columbia
Year: 2008

description: The hydrocarbon order of a membrane bilayer in the hydrocarbon region is suggested to play a fundamental role in maintaining functional integrity in the biological membrane system, Acholeplasma laidlawii strain B. The hydrocarbon order profile, which can be considered to be linearly related to hydrophobic thickness, has been measured by211 NMR methods for a range of Acholeplasma laidlawii membranes containing exogenously incorporated perdeuteriated palmitic acid and a second fatty acid of increasing unsaturation. The microorganism was grown under conditions where de novo fatty acid biosynthesis was suppressed. At 37°C, the growth temperature, there exists a range of hydrocarbon order compatible with good growth characteristics of the microorganism and outside of which the organism grows poorly or not at all. When grown in the presence of cholesterol which is known to increase the orientational order in the hydro-carbon region, it appears that a small fraction of the cholesterol is solubilized by the membrane. A significant fraction of membrane cholesterol, however, is excluded from the lipid bilayer of the microorganism or is in a membrane domain separate from the rest of the lipid. 211 NMR measurements show that this pool of cholesterol is solid –like or crystalline but is available for membrane incorporation using several solubilization methods. It is suggested that the range of hydrocarbon order compatible with good A.laidlawii growth characteristics is maintained even in the presence of cholesterol. Using model membrane systems, T2 relaxation anisotropy measurements have been made for multilamellar vesicles and macroscopically aligned multibilayers by 211 NMRquadrupolar echo techniques. The dominant relaxation mechanism in the multilamellar system is found to be fundamentally different from that in the macroscopically aligned multi bilayers as suggested by the T2 anisotropy found for each. The multi lamellarvesicles show an orientation dependence consistent with such mechanisms as collective lipid motions or surface undulations. The macroscopically aligned multi-layers, however, appear to damp out several of these motional modes as suggested by the anisotropy and also an increase in the magnitudes of the relaxation times obtained. A phenomenological theory developed on the basis of similar experimental results suggests that fluctuations in bilayer thickness could be the mechanism responsible for T2relaxation.
Fixing moduli in exact Type IIA flux vacua

description: Type IIA flux compactifications with O6-planes have been argued from a four dimensional effective theory point of view to admit stable, moduli free solutions. We discuss in detail the ten dimensional description of such vacua and present exact supersymmetric solutions in the case when the O6-charge is smoothly distributed: the geometry is Calabi-Yau and the dilaton is constant. In the localized case, the solution is a half-flat, non-Calabi-Yau metric but still with constant dilaton. Finally, using the ten dimensional description we show how all moduli are stabilized and reproduce precisely the results of de Wolfe et al. Based on arXiv:hep-th/0607223.

Generalized definition of time delay in scattering theory

description: We advocate for the systematic use of a symmetrized definition of time delay in scattering theory. In two-body scattering processes, we show that the symmetrized time delay exists for arbitrary dilated spatial regions symmetric with respect to the origin. It is equal to the usual time delay plus a new contribution, which vanishes in the case of spherical spatial regions. We also prove that the symmetrized time delay is invariant under an appropriate mapping of time reversal. These results are also discussed in the context of classical scattering theory.

description: Coronal mass ejections (CMEs) that exhibit weak or no eruption signatures in the low corona, known as stealth CMEs, are problematic as upon arrival at Earth they can lead to geomagnetic disturbances that were not predicted by space weather forecasters. We investigate the origin and eruption of a stealth event that occurred on 2015 January 3 that was responsible for a strong geomagnetic storm upon its arrival at Earth. To simulate the coronal magnetic field and plasma parameters of the eruption we use a coupled approach. This approach combines an evolutionary nonlinear force-free field model of the global corona with a MHD simulation. The combined simulation approach accurately reproduces the stealth event and suggests that sympathetic eruptions occur. In the combined simulation we found that three flux ropes form and then erupt. The first two flux ropes, which are connected to a large AR complex behind the east limb, erupt first producing two near-simultaneous CMEs. These CMEs are closely followed by a third, weaker flux rope eruption in the simulation that originated between the periphery of AR 12252 and the southern polar coronal hole. The third eruption coincides with a faint coronal dimming, which appears in the SDO/AIA 211 A observations, that is attributed as the source responsible for the stealth event and later the geomagnetic disturbance at 1 AU. The incorrect interpretation of the stealth event being linked to the occurrence of a single partial halo CME observed by LASCO/C2 is mainly due to the lack of STEREO observations being available at the time of the CMEs. The simulation also shows that the LASCO CME is not a single event but rather two near-simultaneous CMEs. These results show the significance of the coupled data-driven simulation approach in interpreting the eruption and that an operational L5 mission is crucial for space weather forecasting.

description: The cultivation of historical reasoning for students is a very important consideration for a successful history class. The aim of the present study is the establishment and the application of a teaching proposition in a history class which utilizes elements of the problem solving method. The problem solving method suggests new ways of learning and understanding historical concepts based on constructivist theories, which set the student in the center of the educational process. The theoretical part consists of the problem solving framework and of issues regarding the applied teaching methods in history lessons. The research part includes the planning and the appliance of the teaching intervention on the “American Revolution” lesson. Furthermore, this part contains the analysis of the students’ learning products aiming to the assessment of the teaching intervention, and especially its contribution to the development of historical reasoning and the acquaintance with the methods of historical research.

description: We investigate the diffusive properties of energy fluctuations in a one-dimensional diatomic chain of hard-point particles interacting through a square--well potential. The evolution of initially localized infinitesimal and finite perturbations is numerically investigated for different density values. All cases belong to the same universality class which can be also interpreted as a Levy walk of the energy with scaling exponent 3/5. The zero-pressure limit is nevertheless exceptional in that normal diffusion is found in tangent space and yet anomalous diffusion with a different rate for perturbations of finite amplitude. The different behaviour of the two classes of perturbations is traced back to the "stable chaos" type of dynamics exhibited by this model. Finally, the effect of an additional internal degree of freedom is investigated, finding that it does not modify the overall scenario

description: Recently, black hole symmetries have been studied widely and it has been speculated that this procedure will lead to the deeper understanding of the black hole physics. Spontaneous symmetry breaking of the horizon symmetries is one of the very recent attempt to clarify black hole thermal physics. In this work, we are going to investigate the same in three dimensional massive gravity, including higher order of Riemann tensor. We observe that the idea also works well in this gravitational theory, thereby providing stronger demand of the viability of this idea.

We consider the diffusion type process $$ dX^ε_t = b(X^ε_t/ε)dt + ε^κσ\big(X^ε_t/ε\big)dB_t, t\le T $$ subject to $X^ε_0=x_0$, where $ε$ is a small positive parameter, $B_t$ is a Brownian motion, independent of $σ$, and $κ> 0$ is a fixed constant. We show that for $κ<1/6$, the family $\{X^ε_t\}_{ε\to 0}$ satisfies the Large Deviations Principle (LDP) of the Freidlin-Wentzell type with the constant drift $\mathbf{b}$ and the diffusion $\mathbf{a}$, given by $$ \mathbf{b}=\sum\limits_{i=1}^m\dfrac{g(a_i)}{a^2_i}π_i\Big/ \sum\limits_{i=1}^m\dfrac{1}{a^2_i}π_i, \quad \mathbf{a}=1\Big/\sum\limits_{i=1}^m\dfrac{1}{a^2_i}π_i, $$ where $\{π_1,...,π_m\}$ is the invariant distribution of the chain $σ(u)$.

description: The effect of the chaotic dynamical states of the agents on the coevolution of cooperation and synchronization in a structured population of the agents remains unexplored. With a view to gaining insights into this problem, we construct a coupled map lattice of the paradigmatic chaotic logistic map by adopting the Watts--Strogatz network algorithm. The map models the agent's chaotic state dynamics. In the model, an agent benefits by synchronizing with its neighbours and in the process of doing so, it pays a cost. The agents update their strategies (cooperation or defection) by using either a stochastic or a deterministic rule in an attempt to fetch themselves higher payoffs than what they already have. Among some other interesting results, we find that beyond a critical coupling strength, that increases with the rewiring probability parameter of the Watts--Strogatz model, the coupled map lattice is spatiotemporally synchronized regardless of the rewiring probability. Moreover, we observe that the population does not desynchronize completely -- and hence finite level of cooperation is sustained -- even when the average degree of the coupled map lattice is very high. These results are at odds with how a population of the non-chaotic Kuramoto oscillators as agents would behave. Our model also brings forth the possibility of the emergence of cooperation through synchronization onto a dynamical state that is a periodic orbit attractor.

description: Game theory deals with strategic interactions among players and evolutionary game dynamics tracks the fate of the players' populations under selection. In this paper, we consider the replicator equation for two-player-two-strategy games involving cooperators and defectors. We modify the equation to include the effect of mutation and also delay that corresponds either to the delayed information about the population state or in realizing the effect of interaction among players. By focusing on the four exhaustive classes of symmetrical games -- the Stag Hunt game, the Snowdrift game, the Prisoners' Dilemma game, and the Harmony game -- we analytically and numerically analyze delayed replicator-mutator equation to find the explicit condition for the Hopf bifurcation bringing forth stable limit cycle. The existence of the asymptotically stable limit cycle imply the coexistence of the cooperators and the defectors; and in the games, where defection is a stable Nash strategy, a stable limit cycle does provide a mechanism for evolution of cooperation. We find that while mutation alone can never lead to oscillatory cooperation state in two-player-two-strategy games, the delay can change the scenario. On the other hand, there are situations when delay alone cannot lead to the Hopf bifurcation in the absence of mutation in the selection dynamics.
Equilibrium statistical mechanics for single waves and wave spectra in Langmuir wave-particle interaction

description: Under the conditions of weak Langmuir turbulence, a self-consistent wave-particle Hamiltonian models the effective nonlinear interaction of a spectrum of M waves with N resonant out-of-equilibrium tail electrons. In order to address its intrinsically nonlinear time-asymptotic behavior, a Monte Carlo code was built to estimate its equilibrium statistical mechanics in both the canonical and microcanonical ensembles. First the single wave model is considered in the cold beam/plasma instability and in the O'Neil setting for nonlinear Landau damping. O'Neil's threshold, that separates nonzero time-asymptotic wave amplitude states from zero ones, is associated to a second order phase transition. These two studies provide both a testbed for the Monte Carlo canonical and microcanonical codes, with the comparison with exact canonical results, and an opportunity to propose quantitative results to longstanding issues in basic nonlinear plasma physics. Then the properly speaking weak turbulence framework is considered through the case of a large spectrum of waves. Focusing on the small coupling limit, as a benchmark for the statistical mechanics of weak Langmuir turbulence, it is shown that Monte Carlo microcanonical results fully agree with an exact microcanonical derivation. The wave spectrum is predicted to collapse towards small wavelengths together with the escape of initially resonant particles towards low bulk plasma thermal speeds. This study reveals the fundamental discrepancy between the long-time dynamics of single waves, that can support finite amplitude steady states, and of wave spectra, that cannot.

description: We present ground-based optical transmission spectroscopy of the low-density hot Jupiter WASP-88b covering the wavelength range 4413-8333 Å with the FORS2 spectrograph on the Very Large Telescope. The FORS2 white light curves exhibit a significant time-correlated noise which we model using a Gaussian Process and remove as a wavelength-independent component from the spectroscopic light curves. We analyse complementary photometric observations from the Transiting Exoplanet Survey Satellite and refine the system properties and ephemeris. We find a featureless transmission spectrum with increased absorption towards shorter wavelengths. We perform an atmospheric retrieval analysis with the AURA code, finding tentative evidence for haze in the upper atmospheric layers and a lower likelihood for a dense cloud deck. Whilst our retrieval analysis results point toward clouds and hazes, further evidence is needed to definitively reject a clear-sky scenario.

description: We study intersecting noncommutative (NC) M5-branes from κ-invariance of an open supermembrane action with constant three-form fluxes. The $κ$-invariance gives rise to possible D-brane configurations for which projection operators can be determined. We construct projection operators for two types of 1/4 BPS intersecting NC M5-branes. The one is an intersection of two NC M5-branes: NC M5\bot NC M5 (3). The other is that of a NC M5-brane and a commutative (C) M5-brane: NC M5\bot C M5 (1). A NC M5-brane can be viewed as a bound state of M5 and M2, and the configurations M2\bot M5 (1) and M2\bot M2 (0) are realized on the intersecting M5-branes. Taking a commutative limit the allowed intersecting M5-branes are surely reproduced: M5\bot M5 (3) and M5\bot M5 (1).

description: An analysis of the classical-quantum correspondence shows that it needs to identify a preferred class of coordinate systems, which defines a torsionless connection. One such class is that of the locally-geodesic systems, corresponding to the Levi-Civita connection. Another class, thus another connection, emerges if a preferred reference frame is available. From the classical Hamiltonian that rules geodesic motion, the correspondence yields two distinct Klein-Gordon equations and two distinct Dirac-type equations in a general metric, depending on the connection used. Each of these two equations is generally-covariant, transforms the wave function as a four-vector, and differs from the Fock-Weyl gravitational Dirac equation (DFW equation).

description: SbPO4 is a complex monoclinic layered material characterized by a strong activity of the non-bonding lone electron pair (LEP) of Sb. The strong cation LEP leads to the formation of layers piled up along the a-axis and linked by weak Sb-O electrostatic interactions. In fact, Sb is 4-fold coordination with O similar to what occurs with the P-O coordination, despite the large difference of ionic radii and electronegativity between both elements. Here we report a joint experimental and theoretical study of the structural and vibrational properties of SbPO4 at high pressure. We show that SbPO4 is not only one of the most compressible phosphates but also one of the most compressible compounds of the ABO4 family. Moreover, it has a considerable anisotropic compression behavior with the largest compression occurring along a direction close to a-axis and governed by the compression of the LEP and the weak inter-layer Sb-O bonds. The strong compression along the a-axis leads to a subtle modification of the monoclinic crystal structure above 3 GPa leading from a 2D to a 3D material. Moreover, the onset of a reversible pressure-induced phase transition is observed above 9 GPa, which is completed above 20 GPa. We propose that the high-pressure phase is a triclinic distortion of the original monoclinic phase. The understanding of the compression mechanism of SbPO4 can aid in understanding the importance of the ion intercalation and catalytic properties of this layered compound.

Persistent pollution with dangerous nanoparticles in Austrian hospitality venues
Creators: name: Neuberger, Manfred

description: Motivation: After the introduction of a partial smoking ban in the Austrian hospitality industry in 2009 poor compliance and pollution with fine particles in 47 Viennese smoking rooms and 23 adjacent non-smoking rooms was found (www.mdpi.com/2073-4433/2/2/171). Because PM1 correlated with air nicotine and was more discriminative than PM2.5, a second survey in 134 rooms of hospitality venues in Vienna included particle number (PN) and lung deposited surface area (www.nature.com/articles/jes201322.pdf). The high pollution with ultrafines found even in the nonsmoking sections, contributed to the legislation of 2015, which banned smoking without exceptions. But a new government cancelled this ban before it entered into force in 2018, arguing with improvements of compliance. Therefore a comparable survey was performed in Graz (Sep.-Nov.) and smaller towns in Lower Austria (Nov.-Dec. 2018). Methods: All indoor samples were taken unannounced and secretly. Immediately after indoor sampling one outdoor sample was taken on the street, where the enterprise was located. In Graz one non-smoking venue was used as an indoor reference for 26 venues where PN was measured in the smoking room and an adjacent non-smoking room. For 20 rural venues in Lower Austria another nonsmoking venue was used as indoor reference. In each room samples were collected for at least 20 minutes by a diffusion size classifier (minidisc G3_016, matter aerosol). Results: Even with doors closed during sampling, transfer of ultrafines from smoking to non-smoking rooms was evident. In non-smoking venues without adjacent smoking rooms, levels were below outdoor concentrations. Conclusion: Contamination of Austrian bars, discos, pubs, cafes and restaurants is still unacceptable.

description: Σκοπός της εργασίας ήταν η εξέταση της ποιητικής θεωρίας του Paul Valéry. Πιο ειδικά αναλύσαμε την κεντρική θέση του Valéry πως η ποίηση είναι στην ουσία της μια τέχνη της γλώσσας, κι έπειτα εκθέσαμε τις απόψεις του για τον ρόλο της αφηρημένης σκέψης και της έμπνευσης στην ποιητική δημιουργία καθώς και για τον αναγνώστη ως συνδιαμορφωτή του τελικού νοήματος ενός ποιήματος. Επίσης, για να κάνουμε σαφέστερη τη θεωρία του Valéry και να δείξουμε πώς αυτή εφαρμόζεται στην πράξη, αναλύσαμε τον τρόπο σύνθεσης ενός βαλερικού ποιήματος, του «Θαλασσινού Κοιμητηρίου». Εν συνεχεία, προσπαθήσαμε να δείξουμε πώς οι συμβολιστές ποιητές E.A. Poe, Charles Baudelaire και Stéfan Mallarmé καθώς και ο θεωρητικός του δόγματος της καθαρής ποίησης, Henri Bremond, επηρέασαν τον Valéry και τον οδήγησαν στην διατύπωση της ποιητικής του θεωρίας, ώστε να θεωρείται ο άμεσος κληρονόμος του συμβολισμού και ο κύριος εκφραστής της καθαρής ποίησης. Τέλος, εξετάσαμε την ελληνική εκδοχή του συμβολισμού και της καθαρής ποίησης στο έργο τού Γιώργου Σεφέρη, αναφερόμενοι σε συγκεκριμένα ποιήματα των ποιητικών του συλλογών «Στροφή» και «Στέρνα», και επιχειρήσαμε την ανάλυση της θεωρίας της ποιητικής γλώσσας του Σεφέρη, επισημαίνοντας παράλληλα τα σημεία σύγκλισης και απόκλισής της με τη θεωρία του Valéry.
description: The purpose of this assignment was the examination of the poetic theory of Paul Valéry. More specifically, we have analysed the cardinal principle of Valéry that poetry is – in essence – an art of language and then we stated his views on the role of abstract thought and the inspiration in the poetic creation as well as the role of the reader himself as a «co-formator» of the final meaning of a poem. Moreover, to make Valéry's theory more explicit and to indicate that it is applied in effect, we analysed the composition of Valéry's poem «Le Cimetiere Marin». In addition, we tried to show that the symbolists E.A. Poe, Charles Baudelaire and Stéfan Mallarmé as well as the theorist of the doctrine of pure poetry, Henri Bremond, influenced Valéry and have led him to put forward his poetic theory so, that he could be considered the direct inheritor of symbolism and the main representative of pure poetry. Finally, we examined the hellenic version of symbolism and pure poetry in the work of George Seferis with reference to certain poems included in his collections of poetry «Strophe» and «The Cistern», and we have also attempted to analyse the theory of Seferis' poetic language highlighting at the same time the points of convergence and divergence with Valéry's theory.

description: Results are presented of early X-ray afterglow observations of GRB 060105 by Swift and Suzaku. The bright, long gamma-ray burst GRB 060105 triggered the Swift Burst Alert Telescope (BAT) at 06:49:28 on 5 January 2006. The Suzaku team commenced a pre-planned target of opportunity observation at 19 ks (5.3 hr) after the Swift trigger. Following the prompt emission and successive very steep decay, a shallow decay was observed from T_0+187 s to T_0+1287 s. After an observation gap during T_0 +(1.5-3) ks, an extremely early steep decay was observed in T_0+(4-30) ks. The lightcurve flattened again at T_0+30 ks, and another steep decay followed from T_0+50 ks to the end of observations. Both steep decays exhibited decay indices of 2.3 - 2.4. This very early break, if it is a jet break, is the earliest case among X-ray afterglow observations, suggesting a very narrow jet whose opening angle is well below 1 degree. The unique Suzaku/XIS data allow us to set very tight upper limits on line emission or absorption in this GRB. For the reported pseudo-redshift of z=4.0+/-1.3 the upper limit on the iron line equivalent width is 50 eV.

description: The study of strong-lensing systems conventionally involves constructing a mass distribution that can reproduce the observed multiply-imaging properties. Such mass reconstructions are generically non-unique. Here, we present an alternative strategy: instead of modelling the mass distribution, we search cosmological galaxy-formation simulations for plausible matches. In this paper we test the idea on seven well-studied lenses from the SLACS survey. For each of these, we first pre-select a few hundred galaxies from the EAGLE simulations, using the expected Einstein radius as an initial criterion. Then, for each of these pre-selected galaxies, we fit for the source light distribution, while using MCMC for the placement and orientation of the lensing galaxy, so as to reproduce the multiple images and arcs. The results indicate that the strategy is feasible, and even yields relative posterior probabilities of two different galaxy-formation scenarios, though these are not statistically significant yet. Extensions to other observables, such as kinematics and colours of the stellar population in the lensing galaxy, is straightforward in principle, though we have not attempted it yet. Scaling to arbitrarily large numbers of lenses also appears feasible. This will be especially relevant for upcoming wide-field surveys, through which the number of galaxy lenses will rise possibly a hundredfold, which will overwhelm conventional modelling methods.

Antiviral activities of selected Chinese medicinal plants

description: Medicinal plants in Yunnan Province of China were collected and screened for antiviral activity. Plants that were used to treat diseases that are now known to have viral causes were selected through a systematic survey of information on traditional Chinese medicine and the traditional medicines of ethnic minority groups in the region. Extracts from 31 species in 22 plant families were assayed for inhibition of Sindbis and murine cytomegalovirus infections in mammalian cell cultures. Sixteen of the species showed antiviral activity. Elsholtzia ciliata (Thunb.) Hyland of the mint family (Lamiaceae) showed the highest activity. It has more than one active component and one of them was purified using bioactivity-guided phytochemical fractionation. The compound was identified as the polycyclic aromatic hydrocarbon fluoranthene and its activity was enhanced with exposure to long wavelength ultraviolet radiation. It has not been previously reported to have antiviral activity. Investigations of the mechanism of action were carried out with the known photosensitive antiviral compound hypercin found in medicinal plants of the genus Hypericum (Hypericaceae). Three hypericin derivatives and five related quinones were tested in structure-activity relationship studies. The new derivative 2,5,9,12-tetra-(carboxyethylthiomethyl) hypericin showed potent photosensitive virucidal activity against membrane-enveloped viruses. The photoaction was demonstrated to be of the singlet oxygen type that could be reduced by the presence of a singlet oxygen scavenger. In comparisons of mechanisms of action with that of hypericin in the presence and absence of light, the two compounds showed similar potencies in light but hypericin was more potent in the dark. Examination of the effect of these compounds on Sindbis virus structural proteins showed that treatment with the derivative in light caused an alteration of the capsid protein, an effect that was not shown in treatments with hypericin.

description: When state parliaments legalised voluntary assisted dying (‘VAD’), they could not have anticipated that the requirement to be ‘an Australian citizen or permanent resident’ would be one of the main areas of controversy. This criterion of eligibility was intended to prevent people travelling from other countries to access VAD. However, because the term ‘permanent resident’ is not defined in the legislation, it has unfortunately prevented some long-term Australian residents from accessing VAD. We evaluate various definitions of ‘permanent resident’ and conclude that a plain English definition better suits the text, context, and purpose of the VAD laws than the technical definitions found in migration or citizenship legislation. We then suggest policy and statutory reform to ameliorate some of the problems which have occurred in practice.
