description: Gluon-initiated double Higgs production is the most important channel to extract the Higgs self-coupling at hadron colliders. However, new physics could enter into this channel in several distinctive ways including, but not limited to, the Higgs self-coupling, a modified top Yukawa coupling, and an anomalous Higgs-top quartic coupling. In this work we initiate a study on the interplay of these effects in the kinematic distributions of the Higgs bosons. More specifically, we divide the transverse momentum and the total invariant mass spectra into two bins and use the differential rates in each bin to constrain the magnitude of the aforementioned effects. Significantly improved results could be obtained over those using total cross section alone. However, some degeneracy remains, especially in the determination of the Higgs trilinear coupling. Therefore, an accurate measurement of the Higgs self-coupling in this channel would require precise knowledge of the magnitudes of other new physics effects. We base our analysis on a future 100 TeV proton-proton collider.

title: Isoseismal Maps of damaging earthquakes in Taranaki, New Zealand, from historical sources - 1882 to 1942
Creators: name: Gurney, James H.
Publisher: name: GNS Science

description: Historical seismicity in the Taranaki region of New Zealand is poorly documented, with only five historical earthquakes known to have caused damage in the region prior to 1942. Of these, only three have origins within the Taranaki region, and only two have had isoseismal maps produced. Utilising a comprehensive collection of historical sources, six further damaging earthquakes that struck the Taranaki region between 1882 and 1942 have been identified. Using macroseismic methods, these six previously undocumented, and one prior-documented, earthquakes had intensities assigned to reported felt locations according to the Modified Mercalli Scale – NZ 2007 (Dowrick et al. 2008). From these intensity datasets, five earthquakes had sufficient data to have isoseismal maps produced for them, allowing magnitude and epicentre estimates to be calculated according to an established attenuation model for isoseismals. This more than doubles the number of historical (pre-1942) earthquakes in the Taranaki region with seismic parameters assessed. The addition of these newly documented damaging earthquakes reveals that the city of New Plymouth has suffered damaging (MM≥6) intensities 11 times since the city’s founding in 1840, with an average return period of
16.6 years. This is more frequent than that in Dowrick and Cousins (2003), who suggested
an average return period of 20 years (auth)

description: Let $β: S^{2n+1}\to S^{2n+1}$ be a minimal homeomorphism ($n\ge 1$). We show that the crossed product $C(S^{2n+1})\rtimes_β \Z$ has rational tracial rank at most one. More generally, let $Ω$ be a connected compact metric space with finite covering dimension and with $H^1(Ω, \Z)=\{0\}.$ Suppose that $K_i(C(Ω))=\Z\oplus G_i$ for some finite abelian group $G_i,$ $i=0,1.$ Let $β: Ω\toΩ$ be a minimal homeomorphism. We also show that $A=C(Ω)\rtimes_β\Z$ has rational tracial rank at most one and is classifiable. In particular, this applies to the minimal dynamical systems on odd dimensional real projective spaces. This was done by studying the minimal homeomorphisms on $X\times Ω,$ where $X$ is the Cantor set.

description: Dissipative Kerr solitons generated in high-Q optical microresonators provide unique opportunities for different up-to-date applications. Increasing the generation efficiency of of such signals is a problem of paramount importance. We provided comprehensive analysis and found optimal conditions providing maximal pump-to-comb conversion efficiency (up to 100\%) for the cases of a free-running and self-injection-locked pump lasers. The dependence of the optimal coupling rate on the pump power was revealed, in addition to the trade-off relations balancing the efficiency and the comb line number. The methods to increase the total comb power were also discussed.
description: Final version does not include some of the basics of the theory (normalization section), but is more clear and full. The title is also changed. Old name "Detailed analysis of ultimate soliton microcomb generation efficiency"
Oblique Shock Breakout in Supernovae and Gamma-Ray Bursts: II. Numerical Solutions For Non-Relativistic Pattern Speeds

description: Non-spherical explosions develop non-radial flows as the pattern of shock emergence progresses across the stellar surface. In supernovae these flows can limit ejecta speeds, stifle shock breakout emission, and cause collisions outside the star. Similar phenomena occur in stellar and planetary collisions, tidal disruption events, accretion-induced collapses, and propagating detonations. We present two-dimensional, nested-grid Athena simulations of non-radial shock emergence in a frame comoving with the breakout pattern, focusing on the adiabatic, non-relativistic limit in a plane stratified envelope. We set boundary conditions using a known self-similar solution and explore the role of box size and resolution on the result. The shock front curves toward the stellar surface, and exhibits a kink from which weak discontinuities originate. Flow around the point of shock emergence is neither perfectly steady nor self-similar. Waves and vortices, which are not predominantly due to grid effects, emanate from this region. The post-shock flow is deflected along the stellar surface, and its pressure disturbs the stellar atmosphere upstream of the emerging shock. We use the numerical results and their analytical limits to predict the effects of radiation transfer and gravity, which are not included in our simulations.

description: We report our findings on a new quasi-periodic oscillation (QPO) and a long period from the ultraluminous X-ray source (ULX) X-2 in nearby galaxy NGC 4736 based on the Chandra and XMM-Newton archival data. To examine the timing properties, power density spectra of the source have been obtained using Fast Fourier Transform. Also the spectral parameters of the source have been calculated by obtaining and fitting the energy spectra. Power density spectrum of this source reveals a QPO peak at $0.73_{-0.14}^{+0.16}$ mHz with an fractional rms variability of 16% using the Chandra data (in the year 2000-lower state of the source). The XMM-Newton data analysis indicates a peak at $0.53_{-0.35}^{+0.09}$ mHz with a fractional rms variation of 5% (in the year 2006-higher state of the source). These recovered QPOs overlap within errors and may be the same oscillation. In addition, we detect a long periodicity or a QPO in the Chandra data of about $(5.2\pm2.0)\times10^{-5}$ Hz ($\sim$ 5.4 hrs) over 3 $σ$ confidence level. If this is a QPO, it is the lowest QPO detected from a ULX. The mass of the compact object in ULX X-2 is estimated using the Eddington luminosity and a disk blackbody model in the range (10$-$80) M_{\sun}.

description: This is a review of new developments in entropic gravity in light of the Relativistic Transactional Interpretation (RTI). A transactional approach to spacetime events can give rise in a natural way to entropic gravity (in the way originally proposed by Erik Verlinde) while also overcoming extant objections to that research program. The theory also naturally gives rise to a Cosmological Constant and to Modified Newtonian Dynamics (MOND) and thus provides a physical explanation for the phenomena historically attributed to "dark energy" and "dark matter".

description: The analysis of the $\mathbb{Z}_2^{3}$ Laplace-Dunkl equation on the $2$-sphere is cast in the framework of the Racah problem for the Hopf algebra $sl_{-1}(2)$. The related Dunkl-Laplace operator is shown to correspond to a quadratic expression in the total Casimir operator of the tensor product of three irreducible $sl_{-1}(2)$-modules. The operators commuting with the Dunkl Laplacian are seen to coincide with the intermediate Casimir operators and to realize a central extension of the Bannai-Ito (BI) algebra. Functions on $S^2$ spanning irreducible modules of the BI algebra are constructed and given explicitly in terms of Jacobi polynomials. The BI polynomials occur as expansion coefficients between two such bases composed of functions separated in different coordinate systems.

description: The paper shows that there is a deep structure on certain sets of bisimilar Probabilistic Automata (PA). The key prerequisite for these structures is a notion of compactness of PA. It is shown that compact bisimilar PA form lattices. These results are then used in order to establish normal forms not only for finite automata, but also for infinite automata, as long as they are compact.

description: We present an analysis of the metallicity and star formation activities of HII regions in the interacting system Arp 86, based on the first scientific observation of the multi-object spectroscopy on the 2.16m Telescope at Xinglong Observatory. We find that the oxygen abundance gradient in Arp 86 is flatter than that in normal disk galaxies, which confirms that gas inflows caused by tidal forces during encounters can flatten the metallicity distributions in galaxies. The companion galaxy NGC 7752 is currently experiencing a galaxy-wide starburst with higher surface density of star formation rate than the main galaxy NGC 7753, which can be explained that the companion galaxy is more susceptible to the effects of interaction than the primary. We also find that the galaxy 2MASX J23470758+2926531 has similar abundance and star formation properties to NGC 7753, and may be a part of the Arp 86 system.

Their high integrated gas velocity dispersions of $σ_{\rm{int}}$=230$^{+40}_{-30}$ km s$^{-1}$, as measured from emission lines of H$_α$ and [OIII], and the resultant M$_{\star}-σ_{\rm{int}}$ relation and M$_{\star}$$-$M$_{\rm{dyn}}$ all match well to those of compact quiescent galaxies at $z\sim2$, as measured from stellar absorption lines. Since log(M$_{\star}$/M$_{\rm{dyn}}$)$=-0.06\pm0.2$ dex, these compact SFGs appear to be dynamically relaxed and more evolved, i.e., more depleted in gas and dark matter ($

description: During the 2011 outburst of the Draconid meteor shower, members of the Video Meteor Network of the International Meteor Organization (IMO) provided, for the first time, fully automated flux density measurements in the optical domain. The data set revealed a primary maximum at 20:09 UT $\pm$5 min on 8 October 2011 (195.036 deg solar longitude) with an equivalent meteoroid flux density of (118 $\pm$10) x 10^-3 km^-2 h^-1 at a meteor limiting magnitude of +6.5, which is thought to be caused by the 1900 dust trail of comet 21P/Giacobini-Zinner. We also find that the outburst had a full width at half maximum (FWHM) of 80 minutes, a mean radiant position of alpha=262.2 deg, delta=+56.2 deg ($\pm$1.3 deg) and geocentric velocity of v_geo=17.4 km/s ($\pm$0.5 km/s). Finally, our data set appears to be consistent with a small sub-maximum at 19:34 UT $\pm$7 min (195.036 deg solar longitude) which has earlier been reported by radio observations and may be attributed to the 1907 dust trail.

description: A register automaton is a finite automaton with finitely many registers ranging from an infinite alphabet. Since the valuations of registers are infinite, there are infinitely many configurations. We describe a technique to classify infinite register automata configurations into finitely many exact representative configurations. Using the finitary representation, we give an algorithm solving the reachability problem for register automata. We moreover define a computation tree logic for register automata and solve its model checking problem.

Classical probability model for Bell inequality

description: We show that by taking into account randomness of realization of experimental contexts it is possible to construct common Kolmogorov space for data collected for these contexts, although they can be incompatible. We call such a construction "Kolmogorovization" of contextuality. This construction of common probability space is applied to Bell's inequality. It is well known that its violation is a consequence of collecting statistical data in a few incompatible experiments. In experiments performed in quantum optics contexts are determined by selections of pairs of angles $(θ_i, θ^\prime_j)$ fixing orientations of polarization beam splitters. Opposite to the common opinion, we show that statistical data corresponding to measurements of polarizations of photons in the singlet state, e.g., in the form of correlations, can be described in the classical probabilistic framework. The crucial point is that in constructing the common probability space one has to take into account not only randomness of the source (as Bell did), but also randomness of context-realizations (in particular, realizations of pairs of angles $(θ_i, θ^\prime_j)$). One may (but need not) say that randomness of "free will" has to be accounted.
Neutrino-heated winds from rotating proto-magnetars

description: We calculate the steady-state properties of neutrino-driven winds from strongly magnetized, rotating proto-neutron stars (`proto-magnetars') under the assumption that the outflow geometry is set by the force-free magnetic field of an aligned dipole. Our goal is to assess proto-magnetars as sites of r-process nucleosynthesis and gamma-ray burst engines. One dimensional solutions calculated along flux tubes corresponding to different polar field lines are stitched together to determine the global properties of the flow at a given neutrino luminosity and rotation period. Proto-magnetars with rotation periods of P~2-5 ms are shown to produce outflows more favorable for the production of third-peak r-process nuclei due to their much shorter expansion times through the seed nucleus formation region, yet only moderately lower entropies, as compared to normal spherical PNS winds. Proto-magnetars with moderately rapid birth periods P~3-5 ms may thus represent a promising Galactic r-process site which is compatible with a variety of other observations, including the recent discovery of possible magnetar-powered supernovae in metal poor galaxies. We also confirm previous results that the outflows from proto-magnetars with P~1-2 ms can achieve maximum Lorentz factors Gamma ~ 100-1000 in the range necessary to power gamma-ray bursts (GRBs). The implications of GRB jets with a heavy nuclei-dominated composition as sources of ultra-high energy cosmic rays are also addressed.

description: Technological advancement in the arena of cyber weaponry has opened the door for new strategies of coercion to be utilized by states. The theory presented in this thesis attempts to understand the future practice of coercion in cyberspace. It argues that destabilizing offensive cyber operations advances the ability of states to achieve coercive success without the necessity of employing conventional kinetic weaponry. A rebuttal to the notion that a destabilizing offensive cyber operation will resemble the attacks on Pearl Harbor is presented. We argue that such an attack would more so resemble the bombing of Hiroshima. This is because such an attack would be chosen in attempt to minimize the loss of civilian life and would simultaneously use all four major strategies of coercion. This conclusion calls into question arguments supporting the “Cyber Pearl Harbor” narrative as well as previous studies which have dismissed the strategic and tactical utility of cyber weaponry. Illustrative case studies concerning the effectiveness of economic sanctions and the economic damage of large-scale attacks, as well as the bombing of Hiroshima and the attack on Pearl Harbor, provide initial validation of the theoretical arguments made here.

description: Die Digitalisierung aller Lebensbereiche hält vermehrt Einzug in die Produktion und bringt häufig disruptive Veränderungen mit sich. Verkürzte Produktlebenszyklen erhöhen den Kosten- und Innovationsdruck. Kunden fordern individuelle Produkte, sodass Unternehmen ihre Flexibilität steigern und eine Produktion bis hin zur Losgröße eins ermöglichen müssen. Durch diese schwer zu prognostizierenden Transformationen finden sich produzierende Unternehmen in einem immer dynamischeren Umfeld wieder. Die neuen Ansätze und Technologien der Industrie 4.0 bieten Möglichkeiten, mit dieser Dynamik umzugehen, aber mit ihnen gehen gleichzeitig auch neue Herausforderungen einher. In der vorliegenden Dissertation wird eine Methodik zur Entscheidungsunterstützung für den Industrie 4.0-Methodeneinsatz vorgestellt, welche die Erstellung einer unternehmensindividuell angepassten Industrie 4.0-Roadmap zum Ziel hat. Die Methodik ist in drei Phasen gegliedert. Grundlage der Methodik ist eine allgemeine Methoden-Toolbox. In dieser sind Industrie 4.0-Methoden mittels eines Rahmenmodells grob strukturiert. Alle Industrie 4.0-Methoden werden durch einen Methodensteckbrief detailliert beschrieben und voneinander abgegrenzt. Darauf aufbauend werden in der ersten Phase für das Unternehmen relevante Methodenstränge anhand betriebstypologischer Merkmale ausgewählt. In der zweiten Phase werden die den Strängen zugehörigen Methoden hinsichtlich strategischer Zielgrößen und des monetären Aufwands bewertet und Einführungsszenarien ausgearbeitet. Basierend auf diesen Einführungsszenarien werden in der dritten Phase Implementierungsreihenfolgen mittels einer System-Dynamics Simulation abgeleitet und eine individuelle Industrie 4.0-Roadmap vorgeschlagen. Die erarbeitete Methodik beschreibt einen umfassenden Ansatz zur Entscheidungsunterstützung bei der Einführung von Industrie 4.0-Methoden in einer Produktionsumgebung durch eine fundierte Analyse des finanziellen und strategischen Potentials. Durch die Anwendung wird eine empfohlene Umsetzungsstrategie für Industrie 4.0 unter Berücksichtigung der spezifischen Unternehmensbedingungen entwickelt.

description: In this work, we study the relations between bounded dynamic regret and the classical notion of asymptotic stability for the case of a priori unknown and time-varying cost functions. In particular, we show that bounded dynamic regret implies asymptotic stability of the optimal steady state for a constant cost function. For the case of an asymptotically stable closed loop, we first derive a necessary condition for achieving bounded dynamic regret. Then, given some additional assumptions on the system and the cost functions, we also provide a sufficient condition ensuring bounded dynamic regret. Our results are illustrated by examples.

description: We shall show equivalence between Palatini-$f(\calR)$ theories and Brans-Dicke (BD) theories at the level of action principles in generic dimension with generic matter coupling. We do that by introducing the Helmholtz Lagrangian associated to Palatini-$f(\calR)$ theory and then performing frame transformations in order to recover Einstein frame and Brans-Dicke frame. This clarifies the relation among different formulations and the transformations among different frames. Additionally, it defines a formulation {\it a lá Palatini} for the Brans-Dicke theory which is dynamically equivalent to metric BD (unlike the standard Palatini-formulation of metric BD theory which are {\it not} dynamically equivalent). In conclusion we discuss interpretation of extended theories of gravitation and perspectives.
Theoretical aspects of simple and nested Fermi surfaces for superconductivity in doped semiconductors and high-$T_C$ cuprates

description: The density-of-states at the Fermi energy, $N(E_F)$, is low in doped superconducting semiconductors and high-$T_C$ cuprates. This contrasts with the common view that superconductivity requires a large electron-boson coupling $λ$ and therefore also a large $N(E_F)$. However, the generic Fermi surfaces (FS) of these systems are relatively simple. Here is presented arguments showing that going from a 3-dimensional multi-band FS to a 2-dimensional and simple FS is energetically favorable to superconductivity. Nesting and few excitations of bosons compensate for a low $N(E_F)$. The typical behavior of the 2-dimensional FS for cuprates, and small 3-dimensional FS pockets in doped semiconductors and diamond, leads to $T_C$ variations as a function of doping in line with what has been observed. Diamond is predicted to attain higher $T_C$ from electron doping than from hole doping, while conditions for superconductivity in Si and Ge are less favorable. A high-$T_C$ material should ideally have few flat and parallel FS sheets with a reasonably large $N(E_F)$.

description: Timed pushdown automata are pushdown automata extended with a finite set of real-valued clocks. Additionaly, each symbol in the stack is equipped with a value representing its age. The enabledness of a transition may depend on the values of the clocks and the age of the topmost symbol. Therefore, dense-timed pushdown automata subsume both pushdown automata and timed automata. We have previously shown that the reachability problem for this model is decidable. In this paper, we study the zenoness problem and show that it is EXPTIME-complete.

description: We calculate the singular field of an accelerated point particle (scalar charge, electric charge or small gravitating mass) moving on an accelerated (non-geodesic) trajectory in a generic background spacetime. Using a mode-sum regularization scheme, we obtain explicit expressions for the self-force regularization parameters. In the electromagnetic and gravitational case, we use a Lorenz gauge. This work extends the work of Barack and Ori [1] who demonstrated that the regularization parameters for a point particle in geodesic motion in a Schwarzschild spacetime can be described solely by the leading and subleading terms in the mode-sum (commonly known as the $A$ and $B$ terms) and that all terms of higher order in $\ell$ vanish upon summation (later they showed the same behavior for geodesic motion in Kerr [2], [3]). We demonstrate that these properties are universal to point particles moving through any smooth spacetime along arbitrary (accelerated) trajectories. Our renormalization scheme is based on, but not identical to, the Quinn-Wald axioms. As we develop our approach, we review and extend work showing that that different definitions of the singular field used in the literature are equivalent to our approach. Because our approach does not assume geodesic motion of the perturbing particle, we are able use our mode-sum formalism to explicitly recover a well-known result: The self-force on static scalar charges near a Schwarzschild black hole vanishes.

description: I present a calculation of next-to-next-to-next-to-leading-order (NNNLO) soft-gluon corrections for top-antitop pair production in hadronic collisions. Approximate NNNLO (aNNNLO) results are obtained by adding the NNNLO soft-gluon corrections to the complete next-to-next-to-leading-order (NNLO) cross section. Theoretical predictions are shown for the total aNNNLO $t{\bar t}$ cross section at LHC and Tevatron energies. The aNNNLO cross sections are larger but have smaller theoretical uncertainties than at NNLO.

description: Within the newly updated version of the ultrarelativistic quantum molecular dynamics (UrQMD) model, the transverse-velocity dependence of the elliptic flow of free nucleons from $^{197}$Au+$^{197}$Au collisions at the incident energy 400 MeV$/$nucleon is studied within different windows of the normalized c.m. rapidity $y_0$. It is found that the elliptic flow difference $v_{2}^{n}$-$v_{2}^{p}$ and ratio $v_{2}^{n}$/$v_{2}^{p}$ of neutrons versus protons are sensitive to the density dependence of the symmetry energy, especially the ratio $v_{2}^{n}$/$v_{2}^{p}$ at small transverse velocity in the intermediate rapidity intervals $0.4

description: Formal methods apply algorithms based on mathematical principles to enhance the reliability of systems. It would only be natural to try to progress from verification, model checking or testing a system against its formal specification into constructing it automatically. Classical algorithmic synthesis theory provides interesting algorithms but also alarming high complexity and undecidability results. The use of genetic programming, in combination with model checking and testing, provides a powerful heuristic to synthesize programs. The method is not completely automatic, as it is fine tuned by a user that sets up the specification and parameters. It also does not guarantee to always succeed and converge towards a solution that satisfies all the required properties. However, we applied it successfully on quite nontrivial examples and managed to find solutions to hard programming challenges, as well as to improve and to correct code. We describe here several versions of our method for synthesizing sequential and concurrent systems.

Optical properties of magnetically doped ultra-thin topological insulator slabs

description: Starting from a three dimensional Hamiltonian, we study the optical properties of ultra-thin topological insulator slabs for which the coupling between Dirac fermions on opposite surfaces results in two degenerated gapped hyperbolic bands. The gap is a threshold for the optical absorption and translates in a peak in the imaginary part of the optical conductivity. An exchange field applied perpendicular to the slab splits the degenerated hyperbolic bands and a double step structure come out in the optical absorption, whereas a double peak structure appears in the imaginary part of the longitudinal optical conductivity. The exchange field breaks time-reversal symmetry and for exchange fields larger than the surfaces coupling gap, the zero frequency Hall conductivity is quantized to $e^2/h$. This result implies large values of the Kerr and Faraday rotation angles. In ultra-thin slabs, the absence of light multiple scattering and bulk conductivity, makes the Kerr and Faradays angles to remain rather large in a wide range of frequencies.

description: We aim to construct a spectral energy distribution (SED) for the emission from the dayside atmosphere of the hot Jupiter WASP-46b and to investigate its energy budget. We observed a secondary eclipse of WASP-46b simultaneously in the g'r'i'z'JHK bands using the GROND instrument on the MPG/ESO 2.2m telescope. Eclipse depths of the acquired light curves were derived to infer the brightness temperatures at multibands that cover the SED peak. We report the first detection of the thermal emission from the dayside of WASP-46b in the K band at 4.2-sigma level and tentative detections in the H (2.5-sigma) and J (2.3-sigma) bands, with flux ratios of 0.253 +0.063/-0.060%, 0.194 +/- 0.078%, and 0.129 +/- 0.055%, respectively. The derived brightness temperatures (2306 +177/-187K, 2462 +245/-302K, and 2453 +198/-258K, respectively) are consistent with an isothermal temperature profile of 2386K, which is significantly higher than the dayside-averaged equilibrium temperature, indicative of very poor heat redistribution efficiency. We also investigate the tentative detections in the g'r'i' bands and the 3-sigma upper limit in the z' band, which might indicate the existence of reflective clouds if these tentative detections do not arise from systematics.

description: The momentum carried by structured light fields exhibits a rich array of surprising features. In this work, we generate transverse orbital angular momentum (TOAM) in the interference field of two parallel and counterpropagating linearly-polarised focused beams, synthesising an array of identical handedness vortices carrying intrinsic TOAM. We explore this structured light field using an optomechanical sensor, consisting of an optically levitated silicon nanorod, whose rotation is a probe of the optical angular momentum, which generates an exceptionally large torque. This simple creation and direct observation of TOAM will have applications in studies of fundamental physics, the optical manipulation of matter and quantum optomechanics.

description: The Whitlam Government had a significant impact on the lives of young people in Australia and their relationship to democracy. In addition to lowering the voting age from 21 years to 18 years, Whitlam Government reforms led to the expansion of the social, political, economic and cultural citizenship of diverse young Australians.
Forty years later the need to consider and strengthen the citizenship rights and relationship of young people to Australian democracy is no less important. While many young people today are engaged with politics – even leading movements such as the Global Climate Strikes – a 2019 Report Card on Children’s Rights in Australia found that Australians under the age of 18 feel they have no voice in this society (Australian Human Rights Commission, 2019). In the context of significant change, complexity and uncertainty in the ecology, economy and politics of Australia and the world, understanding and promoting the participation of young people in democracy is more critical to our future than ever.
This review synthesises Australian and international research published between 2009 and 2019 on young people, democracy, citizenship and participation. Considering the way globalisation shapes youthful politics and citizenship, the review first looks at the international context and then considers the literature on the Australian experience. The review has adopted a broad approach: understanding democracy as constituted through institutions and procedures as well as civic cultures and practices that breach national boundaries. Moreover, as the experience of ‘youth’ is different among young people, in different settings and country contexts, and transitions from ‘childhood’ to ‘adulthood’ are becoming more complex, non-linear and drawn out, the review is inclusive of published research on the political views and practices of people aged 12 – 30.
