description: We report the detection of far-IR CO rotational emission from the prototypical Seyfert 2 galaxy NGC 1068. Using Herschel-PACS, we have detected 11 transitions in the J_upper=14-30 (E_upper/k_B = 580-2565 K) range, all of which are consistent with arising from within the central 10" (700 pc). The detected transitions are modeled as arising from 2 different components: a moderate excitation (ME) component close to the galaxy systemic velocity, and a high excitation (HE) component that is blueshifted by ~80 km s^{-1}. We employ a large velocity gradient (LVG) model and derive n_H2~10^{5.6} cm^{-3}, T_kin~170 K, and M_H2~10^{6.7} M_sun for the ME component, and n_H2~10^{6.4} cm^{-3}, T_kin~570 K, and M_H2~10^{5.6} M_sun for the HE component, although for both components the uncertainties in the density and mass are plus/minus (0.6-0.9) dex. We compare the CO line profiles with those of other molecular tracers observed at higher spatial and spectral resolution, and find that the ME transitions are consistent with these lines arising in the ~200 pc diameter ring of material traced by H_2 1-0 S(1) observations. The blueshift of the HE lines may also be consistent with the bluest regions of this H_2 ring, but a better kinematic match is found with a clump of infalling gas ~40 pc north of the AGN. We discuss the prospects of placing the HE component near the AGN, and conclude that while the moderate thermal pressure precludes an association with the ~1 pc radius H_2O maser disk, the HE component could potentially be located only a few parsecs more distant from the AGN, and might then provide the N_H~10^{25} cm^{-2} column obscuring the nuclear hard X-rays. Finally, we also report sensitive upper limits extending up to J_upper=50, which place constraints on a previous model prediction for the CO emission from the X-ray obscuring torus. [Abridged]

L’“infinito” nella riflessione di Edmund Burke
Creators: name: Ferri, Michela

description: É noto che l’idea dell’“infinito” costituisce uno dei punti cardine della definizione burkeiana del concetto di “sublime”. Dall’analisi contenuta nell’Enquiry il lettore comprenderà che non è nell’infinito “naturale”, bensì, in quello “artificiale”, che Burke rintraccia l’autentico significato di tale idea, così come essa si presenta all’uomo attraverso la sua percezione degli elementi che osserva. Sono due gli aspetti che emergono dall’originale definizione che Burke elabora del concetto di “infinito artificiale”: il primo, quello della pura illusione, considerando che la struttura dell’infinito è quella dell’inganno; il secondo, quello dell’inscindibilità del sublime dall’oggetto: sappiamo che il sublime non può astrarsi dall’oggetto percepito e che, quindi, l’infinito non può che essere inteso come “artificiale”.

description: The indirect detection of dark matter requires that dark matter annihilation products be discriminated from conventional astrophysical backgrounds. Here, we re-analyze GeV-band gamma-ray observations of the prominent Milky Way dwarf satellite galaxy Segue 1, for which the expected astrophysical background is minimal. We explicitly account for the angular extent of the conservatively expected gamma-ray signal and keep the uncertainty in the dark-matter profile external to the likelihood analysis of the gamma-ray data.

description: We consider the evolution of scale-free networks according to preferential attachment schemes and show the conditions for which the exponent characterizing the degree distribution is bounded by upper and lower values. Our framework is an agent model, presented in the context of economic networks of trades, which shows the emergence of critical behavior. Starting from a brief discussion about the main features of the evolving network of trades, we show that the logarithmic return distributions have bounded heavy-tails, and the corresponding bounding exponent values can be derived. Finally, we discuss these findings in the context of model risk.
Il riso di Molière. Teatro e impersonalità

Publisher: name: Università degli Studi di Milano

description: In un breve e intenso lavoro del 1900 – che raccoglie tre saggi scritti l’anno precedente – Henri Bergson si cimenta nel difficile compito di definire l’essenza «volatile» del riso, arrivando a concepirlo alla stregua d’un rilevatore sociale di forze impersonali. Strumento d’indagine privilegiato di conoscenza diviene per il filosofo francese la commedia di Molière, già oggetto d’indagine delle riflessioni di Du Bos e Diderot, che richiameremo in questo saggio nel tentativo di guadagnare a nostra volta un primo passo verso la definizione della peculiare impersonalità che anima la commedia; fra le arti, come scrive Bergson, quella che maggiormente «oscilla fra l’arte e la vita».

Quest’ultimo comporta il riconoscimento di un'importante funzione morale al genere poetico non solo sul piano normativo ma anche su quello pratico-effettivo della riflessione morale rousseauiana.

Insights from the Northern Creative Corridor Workshops Sprint
Creators: name: Choudhry, Iqra

Publisher: name: Creative Industries Policy and Evidence Centre (Creative PEC)
Year: 2024

description: The Northern Creative Corridor is a live initiative that aims to join-up creative clusters and microclusters across the North of England to drive regional growth in the creative industries. It is led by a coalition of national and regional partners, including the Royal Society of Arts, Creative PEC, Arts Council England, the BBC and several Northern Mayors, who are working together to develop a pan-regional strategy that can harness national and devolved powers, as well as coordinate industry action. 

Previous analysis has highlighted the significant economic growth a creative corridor could help unlock for the region: if the creative industries’ 3% contribution to gross value added (GVA) in the North were to rise to half that of London and the South East’s 10% share of GVA, it could lead to a GVA boost of up to £10 billion by 2030.  

This briefing paper is intended to help inform the development of a workplan for the Northern Creative Corridor. It summarises key insights from a series of policy workshops run by the Creative PEC and the RSA between November 2023 and February 2024 with over 70 stakeholders from across industry, local and national government. The workshops sought to identify the perceived barriers and enablers of growth in the North of England’s creative industries, before co-designing policy intervention ideas. 

This is an edited version of a paper presented to signatories of the Northern Creative Corridor Charter at a Summit in February 2024. The policy ideas and insights included here are intended as starting points for further development, rather than definitive recommendations.

Building collaborative partnerships in primary health care
Creators: name: Riley, Marie Danielle Melinda Mylo
Publisher: name: University of British Columbia
Year: 2013

description: Collaboration is an increasingly adopted strategy for addressing many of society's most complex and pressing public challenges. The General Practice Services Committee’s Divisions of Family Practice initiative offers a rich example of collaborative partnerships in action within the context of the primary health care system of British Columbia. Divisions of Family Practice are community-based nonprofit organizations consisting of family physician members. Division members work in partnership with health authority administrators and other community organization representatives with the goal of working at local and regional levels, through collaborative processes, to co-design locally feasible solutions for better delivery of primary health care services leading to improved provider and patient satisfaction. The research focuses on the question, “How can Divisions create and sustain effective collaborative practices”? This question is explored through a practitioner inquiry. The inquiry includes: a description of the General Practice Services Committee and the Divisions of Family Practice initiative; a review of the relevant literature; observations and reflections on the experience of collaborative process within the Divisions initiative from my perspective as an administrator supporting the initiative; and concludes by suggesting that further study in the areas of initiative sustainability, inclusive patient involvement, and a more culturally diverse leadership would be beneficial. The findings of the inquiry support the notion that educating about the processes of collaboration, the inherent obstacles and challenges, and the role of the behaviours of the participants, are instrumental in supporting effective collaborative partnerships. The inquiry has informed the second part of thesis, a participation guide and process handbook designed to share a model, processes and tools to foster the collaborative work of the Divisions and their partners.

Families of forbidden configurations
Creators: name: Koch, Christina Louise
Publisher: name: University of British Columbia
Year: 2013

description: The forbidden configuration problem arises from a question in extremal set theory. The question seeks a bound on the maximum number of subsets of an m-set given that some trace is forbidden. In terms of hypergraphs, we seek the maximum number of edges on a simple hypergraph of m vertices such that this hypergraph does not contain a forbidden sub-hypergraph. We will use the notation of matrices to describe the problem as follows. We call a (0,1)-matrix simple if it has no repeated columns; this will be the analogue of a simple hypergraph. Let F be a given matrix. We say that a (0,1)-matrix A contains F as a configuration if there is some submatrix of A that is a row and column permutation of F. This is equivalent to a hypergraph containing some sub-hypergraph. F need not be simple. We define forb(m, F ) as the maximum number of columns possible for a simple, m-rowed, (0,1)-matrix that does not contain F as a configuration. A variation of the forbidden configuration problem forbids a family of configurations F = {F₁, F₂, ... Fn} instead of a single configuration F. Thus, forb(m, F) becomes the maximum number of columns possible for a simple, m-rowed, (0,1)-matrix that does not contain any one of the matrices in the family as a configuration. We will present a series of results organized by the character of forb(m, F). These include a classification of families such that forb(m, F) is a constant and the unexpected result that for a certain family, forb(m, F) is on the order of m³/², where previous results typically had forb(m, F) on the order of integer powers of m. We will conclude with a case study of families of forbidden configurations and suggestions for future work.

Lower bounds on the Probability of Error for Classical and Classical-Quantum Channels

description: In this paper, lower bounds on error probability in coding for discrete classical and classical-quantum channels are studied. The contribution of the paper goes in two main directions: i) extending classical bounds of Shannon, Gallager and Berlekamp to classical-quantum channels, and ii) proposing a new framework for lower bounding the probability of error of channels with a zero-error capacity in the low rate region. The relation between these two problems is revealed by showing that Lovász' bound on zero-error capacity emerges as a natural consequence of the sphere packing bound once we move to the more general context of classical-quantum channels. A variation of Lovász' bound is then derived to lower bound the probability of error in the low rate region by means of auxiliary channels. As a result of this study, connections between the Lovász theta function, the expurgated bound of Gallager, the cutoff rate of a classical channel and the sphere packing bound for classical-quantum channels are established.

description: We critically investigate current statistical tests applied to high redshift clusters of galaxies in order to test the standard cosmological model and describe their range of validity. We carefully compare a sample of high-redshift, massive, galaxy clusters with realistic Poisson sample simulations of the theoretical mass function, which include the effect of Eddington bias. We compare the observations and simulations using the following statistical tests: the distributions of ensemble and individual existence probabilities (in the >M,>z sense), the redshift distributions, and the 2d Kolmogorov-Smirnov test. Using seemingly rare clusters from Hoyle et al. (2011), and Jee et al. (2011) and assuming the same survey geometry as in Jee et al. (2011, which is less conservative than Hoyle et al. 2011), we find that the (>M,>z) existence probabilities of all clusters are fully consistent with LCDM. However assuming the same survey geometry, we use the 2d K-S test probability to show that the observed clusters are not consistent with being the least probable clusters from simulations at >95% confidence, and are also not consistent with being a random selection of clusters, which may be caused by the non-trivial selection function and survey geometry. Tension can be removed if we examine only a X-ray selected sub sample, with simulations performed assuming a modified survey geometry.

description: We present Hubble Space Telescope and simultaneous Swift X-ray telescope observations of the strongest candidate intermediate mass black hole ESO 243-49 HLX-1. Fitting the spectral energy distribution from X-ray to near-infrared wavelengths showed that the broadband spectrum is not consistent with simple and irradiated disc models, but is well described by a model comprised of an irradiated accretion disc plus a stellar population with a mass ~1E6 Msun. The age of the population cannot be uniquely constrained, with both very young and very old stellar populations allowed. However, the very old solution requires excessively high levels of disc reprocessing and an extremely small disc, leading us to favour the young solution with an age of ~13 Myr. In addition, the presence of dust lanes and the lack of any nuclear activity from X-ray observations of the host galaxy lead us to propose that a gas-rich minor merger may have taken place less than ~200 Myr ago. Such a merger event would explain the presence of the intermediate mass black hole and support a young stellar population.

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We study the properties of a line junction which separates the surfaces of two three-dimensional topological insulators. The velocities of the Dirac electrons on the two surfaces may be unequal and may even have opposite signs. For a time reversal invariant system, we show that the line junction is characterized by an arbitrary parameter αwhich determines the scattering from the junction. If the surface velocities have the same sign, we show that there can be edge states which propagate along the line junction with a velocity and orientation of the spin which depend on αand the ratio of the velocities. Next, we study what happens if the two surfaces are at an angle ϕwith respect to each other. We study the scattering and differential conductance through the line junction as functions of ϕand α. We also find that there are edge states which propagate along the line junction with a velocity and spin orientation which depend on ϕ. Finally, if the surface velocities have opposite signs, we find that the electrons must transmit into the two-dimensional interface separating the two topological insulators.

description: A Ricci surface is a Riemannian 2-manifold $(M,g)$ whose Gaussian curvature $K$ satisfies $KΔK+g(dK,dK)+4K^3=0$. Every minimal surface isometrically embedded in $\mathbb{R}^3$ is a Ricci surface of non-positive curvature. At the end of the 19th century Ricci-Curbastro has proved that conversely, every point $x$ of a Ricci surface has a neighborhood which embeds isometrically in $\mathbb{R}^3$ as a minimal surface, provided $K(x)<0$. We prove this result in full generality by showing that Ricci surfaces can be locally isometrically embedded either minimally in $\mathbb{R}^3$ or maximally in $\mathbb{R}^{2,1}$, including near points of vanishing curvature. We then develop the theory of closed Ricci surfaces, possibly with conical singularities, and construct classes of examples in all genera $g\geq 2$.

Relativistic iron K X-ray Reverberation in NGC 4151

description: Recent X-ray observations have enabled the study of reverberation delays in AGN for the first time. All the detections so far are in sources with a strong soft excess, and the measured delay is between the hard (1-3 keV) direct continuum and the soft excess (0.5-1 keV), interpreted as the reflection continuum smeared by relativistic effects. There is however an inherent ambiguity in identifying and studying the details of the lines in the soft excess. Here we report the first detection of reverberation in the iron K band in any AGN. Using XMM-Newton observations of NGC 4151, we find delays of order 2000 s on time-scales of 10e5 s between the 5-6 keV band and 2-3 and 7-8 keV bands, with a broad lag profile resembling a relativistically-broadened iron line. The peak of the lag spectra shifts to lower energies at higher frequencies, consistent with the red wing of the line being emitted at smaller radii, as expected from reflection off the inner accretion disk. This is a first detection of a broad iron line using timing studies.

description: Arts-based approaches have not been widely used in the drug and alcohol treatment sector. In this study, we examined the utility of the arts-based method of Body Mapping in an Australian residential treatment centre. Two workshops were held to explore young people’s strengths and support networks in order to improve understandings of young people’s lives, identities and experiences of treatment. Semi-structured follow-up interviews were conducted and triangulated with observational notes and staff interviews. We identified four major themes: engaging through art; removing the mask; revealing strengths; and a sense of achievement. Overall, this study highlighted the value of Body Mapping as an approach to engage with young people, providing rich in-depth data about their lived experiences, including in the alcohol and other drug (AOD) treatment context.

description: The two-point function for tensor metric perturbations around de Sitter spacetime including one-loop corrections from massless conformally coupled scalar fields is calculated exactly. We work in the Poincaré patch (with spatially flat sections) and employ dimensional regularization for the renormalization process. Unlike previous studies we obtain the result for arbitrary time separations rather than just equal times. Moreover, in contrast to existing results for tensor perturbations, ours is manifestly invariant with respect to the subgroup of de Sitter isometries corresponding to a simultaneous time translation and rescaling of the spatial coordinates. Having selected the right initial state for the interacting theory via an appropriate iεprescription is crucial for that. Finally, we show that although the two-point function is a well-defined spacetime distribution, the equal-time limit of its spatial Fourier transform is divergent. Therefore, contrary to the well-defined distribution for arbitrary time separations, the power spectrum is strictly speaking ill-defined when loop corrections are included.

title: DEPRECATED: Design models for multimedia learning environments based on interactive drama
Creators: name: Rogers, Thomas John
Publisher: name: University of Plymouth
Year: 2000

description: Interactive multimedia offers a degree of richness that lies outside the scope of conventional design methods for computer based learning. This research seeks to develop an interdisciplinary approach to design, that recognises the ways in which the combination and integration of different media forms can be exploited to stimulate experiential, intuitive, perceptual, and social/communicative aspects of learning. The goal of the project has been to develop a conceptual design model for the development of multimedia learning environments (MLEs), for humanistic learning applications, by using interactive drama. The models and methods developed though a practical design project have been founded upon theory from the realms of psychology, social sciences, learning and education, the arts and media, and software design. They address the cognitive and social aspects of learning, the use and interpretation of interactive media, the creation of learning environments, and the activities involved in design. As a vehicle to test the theoretical perspective, a design project has been undertaken, that has involved: 0 learning needs analysis and subject matter development; 9 development of a structural model for the MLE; 9 information structure, navigation and interface design; scripting, design and development of media materials for the development of interactive drama; formative evaluation. The subject area chosen for the design project is that of pregnancy and childbirth. The primary reasons for this choice was a desire to address the issues of design for informal learning experiences (that do not fit in the remit of institutional curricula) and an interest in finding ways to represent the social and interpersonal dimension to learning. Such learning processes have been described as `humanistic learning' for the purposes of this research project. To help fulfil these goals, it was decided to work with playwright Simon Turley to develop a number of interactive drama scenes. Not only did this enable some of the more sensitive and personal issues of pregnancy to be addressed, but it also gave an opportunity to explore the world of drama, film and theatre as a means to create interactive learning experiences. The research has shown the benefits of interdisciplinary design practice, produced a framework of the theoretical issues that inform designers, and developed an approach to the design of MLEs for humanistic learning applications. These elements have been brought together to form the conceptual design model.

Integral Tate modules and splitting of primes in torsion fields of elliptic curves

Publisher: name: arXiv
Year: 2012
Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: Let $E$ be an elliptic curve over a finite field $k$, and $\ell$ a prime number different from the characteristic of $k$. In this paper we consider the problem of finding the structure of the Tate module $T_\ell(E)$ as an integral Galois representations of $k$. We indicate an explicit procedure to solve this problem starting from the characteristic polynomial $f_E(x)$ and the $j$-invariant $j_E$ of $E$. Hilbert Class Polynomials of imaginary quadratic orders play here an important role. We give a global application to the study of prime-splitting in torsion fields of elliptic curves over number fields.

Child immigrants to the "edge of empire" : Fairbridge child migrants and British Columbia's quest for the construction of the "white man's province"
Creators: name: Vallance, Daniel
Publisher: name: University of British Columbia
Year: 2013

description: Beginning in the 1860s British children participated in migration schemes to Canada. Philanthropists, motivated by evangelical beliefs and despair at the state of childhood for homeless and dependent children in Britain, would send 80,000 British boys and girls to Canada between 1867 and 1929. Placed with Canadian families in rural communities, the schemes directed these children toward lives as farm labourers and housewives. By the 1920s, rampant opposition to these child migration schemes in central and eastern Canada brought about their termination. Opponents of child migration, mobilized the language of eugenics to condemn the children sent to Canada as “degenerate castoffs” of British society, and argued that the children were beyond saving and posed a threat to Canadian society. This was not the end of child migration to Canada, however, for in 1935 the Fairbridge Society, a rescue organization, opened the Prince of Wales Fairbridge Farm School in British Columbia. This final scheme would see 329 children sent to British Columbia before its demise in 1950. The earlier period of child migration to Canada, 1860 to 1929, has received the majority of scholarly attention with the recommencement in 1935 often overlooked. This thesis examines how the Fairbridge Farm School at Cowichan Station was able to open and operate in British Columbia without popular opposition by exploring how British Columbian constructions of whiteness were projected onto and internalized by the operators of the Farm School and its children, and in doing this incorporate the Fairbridge Farm School into the larger narrative of child migration to Canada.
Spatially inhomogeneous linear inverse problems with possible singularities

description: The objective of the present paper is to introduce the concept of a spatially inhomogeneous linear inverse problem where the degree of ill-posedness of operator $Q$ depends not only on the scale but also on location. In this case, the rates of convergence are determined by the interaction of four parameters, the smoothness and spatial homogeneity of the unknown function $f$ and degrees of ill-posedness and spatial inhomogeneity of operator $Q$. Estimators obtained in the paper are based either on wavelet-vaguelette decomposition (if the norms of all vaguelettes are finite) or on a hybrid of wavelet-vaguelette decomposition and Galerkin method (if vaguelettes in the neighborhood of the singularity point have infinite norms). The hybrid estimator is a combination of a linear part in the vicinity of the singularity point and the nonlinear block thresholding wavelet estimator elsewhere. To attain adaptivity, an optimal resolution level for the linear, singularity affected, portion of the estimator is obtained using Lepski [Theory Probab. Appl. 35 (1990) 454-466 and 36 (1991) 682-697] method and is used subsequently as the lowest resolution level for the nonlinear wavelet estimator. We show that convergence rates of the hybrid estimator lie within a logarithmic factor of the optimal minimax convergence rates. The theory presented in the paper is supplemented by examples of deconvolution with a spatially inhomogeneous kernel and deconvolution in the presence of locally extreme noise or extremely inhomogeneous design. The first two problems are examined via a limited simulation study which demonstrates advantages of the hybrid estimator when the degree of spatial inhomogeneity is high. In addition, we apply the technique to recovery of a convolution signal transmitted via amplitude modulation.
