description: This paper gives details of an interface constructed to allow the coupling of the ORANI applied general equilibrium model and the Murphy macrodynamic model. It shows how the previously developed methodology for interfacing a continuous-time macro model with a comparative static general equilibrium model (Cooper, McLaren and Powell (1985)) can be adapted to accommodate a macro model formulated in discrete time. The Murphy Model (MM) includes a model of the housing sector. This allows the interfaced ORANI/MM system to have investment in housing activity determined by MM, which (unlike ORANI) links housing investment directly to conditions in financial markets. A by-product of the interfacing procedure is an empirical estimate of the ORANI short run. Under a calibrating shock in which real government spending increases permanently by 10 per cent relative to control, and this fiscal expansion is financed about equiproportionately from bond issue and monetary expansion, the estimated ORANI short run turns out to be eight quarters, confirming earlier work. It was found possible to solve for 'as-if' shocks in the macroeconomic environment which, when injected into ORANI in stand-alone mode, would reproduce the macroeconomic projections of MM to a good first approximation. Thus it proved possible to use ORANI to disaggregate to the level of 112 industries the macroeconomic projections produced by MM.

description: Deep X-ray surveys have resolved much of the X-ray background radiation below 2 keV into discrete sources, but the background above 8 keV remains largely unresolved. The obscured (type 2) Active Galactic Nuclei (AGNs) that are expected to dominate the hard X-ray background have not yet been detected in sufficient numbers to account for the observed background flux. However, deep X-ray surveys have revealed large numbers of faint quiescent and starburst galaxies at moderate redshifts. In hopes of recovering the missing AGN population, it has been suggested that the defining optical spectral features of low-luminosity Seyfert nuclei at large distances may be overwhelmed by their host galaxies, causing them to appear optically quiescent in deep surveys. We test this possibility by artificially redshifting a sample of 23 nearby, well-studied active galaxies to z = 0.3, testing them for X-ray AGN signatures and comparing them to the objects detected in deep X-ray surveys. We find that these redshifted galaxies have properties consistent with the deep field ``normal'' and ``optically bright, X-ray faint'' (OBXF) galaxy populations, supporting the hypothesis that the numbers of AGNs in deep X-ray surveys are being underestimated, and suggesting that OBXFs should not be ruled out as candidate AGN hosts that could contribute to the hard X-ray background source population.

description: An irreducible supercuspidal representation 𝜋 of 𝐺 = GL(n, 𝐹), where 𝐹 is a nonarchimedean local field of characteristic zero, is said to be “distinguished” by a subgroup 𝐻 of 𝐺 and a quasicharacter 𝒳 of 𝐻 if Hom𝐻(𝜋, 𝒳) ≠ 0. There is a suitable global analogue of this notion for an irreducible, automorphic, cuspidal representation associated to GL(n). Under certain general hypotheses, it is shown in this paper that every distinguished, irreducible, supercuspidal representation may be realized as a local component of a distinguished, irreducible automorphic, cuspidal representation. Applications to the theory of distinguished supercuspidal representations are provided.

description: The MPIGLOG specification of an indirect utility function leads to a parametric representation in terms of expenditure and two unit cost functions. Specification of these unit cost functions in terms of regular, flexible functions leads to the notion of an "effectively globally regular" system of demand equations. Three examples demonstrate the success of such a specification in achieving regularity and flexibility.

title: 'You Were Born Again With Us': Narratives of Italian Families Formed Through International Adoption
Creators: name: Narzisi, Katia
Publisher: name: The Open University
Year: 2016

description: This thesis presents a qualitative study of adoptive parents, childrens, young adults and experts’ accounts of communication within families about a child’s past. Until now, this particular aspect of international adoption in Italy has received little attention. The aims of this study are to understand how both parents and adoptees’ deal with and manage the origins of adoptees, and also experts’ views of this communication. In addition, this research explores the potentiality of the use of 'life-story work’ amongst this specific sample. This study uses in-depth interviews to unravel the experiences of ten adoptive parents with their five adopted children and five young adopted adults. It also includes the perspectives of seven experts. The findings are embedded in the Italian social and cultural context, which contributes to shaping the meaning of the accounts collected. The findings show that all of the families had developed an adoption story. Visual aids and documents help and support the telling of these stories. Furthermore, the various stories served different functions: they enabled communication, they presented challenges, and they emphasised the relationships with the actors involved in international adoption. The findings show diversity in the approaches to communicative openness: the practices presented by the sample families in this research are organised according to four different approaches to communication. The differences amongst the families, children and young adults are linked to the amount of information available to the families; the child’s attitude to his or her past; the influence of the actors involved in the adoption; the way in which adoptive kinship is understood; the way in which the laws are applied, and the ways in which children’s voices and needs are accounted for by families and accredited bodies.
Universal finite-size scaling analysis of Ising models with long-range interactions at the upper critical dimensionality: Isotropic case

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We investigate a two-dimensional Ising model with long-range interactions that emerge from a generalization of the magnetic dipolar interaction in spin systems with in-plane spin orientation. This interaction is, in general, anisotropic whereby in the present work we focus on the isotropic case for which the model is found to be at its upper critical dimensionality. To investigate the critical behavior the temperature and field dependence of several quantities are studied by means of Monte Carlo simulations. On the basis of the Privman-Fisher hypothesis and results of the renormalization group the numerical data are analyzed in the framework of a finite-size scaling analysis and compared to finite-size scaling functions derived from a Ginzburg-Landau-Wilson model in zero mode (mean-field) approximation. The obtained excellent agreement suggests that at least in the present case the concept of universal finite-size scaling functions can be extended to the upper critical dimensionality.

description: This article explores the geometric pattern found in the illumination of the Quran mushaf using an art formalistic approach. The study involves a visual analysis of the illumination focusing on elements of art and principles of design. The research uses Adobe Illustrator to analyse these geometric patterns, particularly highlighting the presence of rosettes or medallions, which resemble glowing stars or the sun, aligning with the concept of "Shamsa" (light). The findings contribute new insights into the field of art, particularly in understanding the geometric aspects of Quranic mushaf.

description: While the Almost Ideal Demand System (AIDS) has received increasing attention in empirical studies of consumer demand, the fact that the underlying PIGLOG cost function is not globally regular has often led to violation of negative semi-definiteness in the estimated Slutsky matrix. This paper suggests a modification to the PIGLOG class of preferences, termed MPIGLOG, which preserves regularity in a wider region of expenditure- price space. In an empirical section the AIDS special case of PIGLOG is compared with the analogous special case of MPIGLOG, which we term MAIDS. The comparison demonstrates the improved regularity features of MAIDS.

Spin-torque switching mechanisms of perpendicular magnetic tunnel junctions nanopillars

description: Understanding the magnetization dynamics induced by spin transfer torques in perpendicularly magnetized magnetic tunnel junction nanopillars and its dependence on material parameters is critical to optimizing device performance. Here we present a micromagnetic study of spin-torque switching in a disk-shaped element as a function of the free layer's exchange constant and disk diameter. The switching is shown to generally occur by 1) growth of the magnetization precession amplitude in the element center; 2) an instability in which the reversing region moves to the disk edge, forming a magnetic domain wall; and 3) the motion of the domain wall across the element. For large diameters and small exchange, step 1 leads to a droplet with a fully reversed core that experiences a drift instability (step 2). While in the opposite case (small diameters and large exchange), the central region of the disk is not fully reversed before step 2 occurs. The origin of the micromagnetic structure is shown to be the disk's non-uniform demagnetization field. Faster, more coherence and energy efficient switching occur with larger exchange and smaller disk diameters, showing routes to increase device performance.
title: Creating City Cyclists: Understanding Why People Start, and Sometimes Stop, Cycling in South London
Creators: name: Wood, Peter Robert Haddon
Publisher: name: The Open University
Year: 2015

description: Cycling can be framed as a means of practically re-ordering movement, connection and experience. Drawing upon readings in mobility and urban studies, the thesis addresses deficiencies in practice theory by investigating how to better conceptualise dynamic change, socio-technical multiplicity, and embodied experiences of technology. Investigating people’s experiences of using bicycles to live in a city, it asks how the take up, alteration and divestment of different practices might influence how urban times and spaces are practically ordered. The study develops disciplinary debates on place and practice by engaging with the theoretical concepts of emergence, encounter and cosmogony. It empirically investigates three sub-questions: how are cycling-journeys experienced in London; how do experiences of cycling the city alter urban practice; and how does cycling influence the practical remaking of urban place? Methodologically, 20 participants were recruited for a year’s fieldwork comprised of 3 methods; ride-along with videoelicitation, diary-interview and focus groups. This iteratively investigated three practices; civility, navigation and placemaking. Understanding the urban as a means and outcome of systematised contingent ordering - a machinic complex -the study suggests that cycling reconfigures how such ordering occurs. Rather than investigating practices of cycling it investigates how urban practices incorporate experiences of cycling and might bedisseminated, intensified, disrupted, or reconfigured. By decentring cycling and fracturing the study’s focal point, the framework facilitates a conceptualisation of urban practices as traversing an array of contingent situations, via a variety of technologically-mediated engagements. The findings explore how quotidian mobility creates durable social forms and places through transient, mounted but systematised and repeated meetings in the street. This refines our understanding of the spatial and performative. It argues that creative repairs making modest alterations to elements of skill, meaning and infrastructure might catalyse more radical systemic reconfigurations of their links, or initiate self-perpetuating trajectories of further change.

description: This paper considers the twin problems of testing for ARCH and GARCH disturbances in the linear regression model. A feature of these testing problems, ignored by the standard Lagrange multiplier test, is that they are one-sided in nature. A test which exploits this one-sided aspect is constructed based on the sum of the scores. Its small-sample size and power properties under both normal and leptokurtic disturbances are investigated via a Monte Carlo experiment. The results indicate that the new test typically has superior power to two versions of the Lagrange multiplier test and possibly also more accurate asymptotic critical values.

description: We mathematically analyze a simple market model where trading at each point in time involves only two agents with the sum of their money being conserved and with neither parties resulting with negative money after the interaction process. The exchange involves random re-distribution among the two players of a fixed fraction of their total money. We obtain a simple integral nonlinear equation for the money distribution. We find that the zero savings and finite savings cases belong to different universality classes. While the zero savings case can be solved analytically, the finite savings solution is obtained by numerically solving the integral equation. We find remarkable agreement with results obtained by other researchers using sophisticated numerical techniques.

description: The multi-wavelength spectrum observed from M87 extends from radio wavelengths up to TeV gamma-ray energies. The radio through GeV components have been interpreted successfully using SSC models based on misaligned blazar jets, but the origin of the intense TeV emission detected during flares in 2004, 2005, and 2010 remains puzzling. It has been previously suggested that the TeV flares are produced when a relativistic proton jet originating in the core of M87 collides with a molecular cloud (or stellar atmosphere) located less than one parsec from the central black hole. We explore this scenario in detail here using a self-consistent model for the acceleration of relativistic protons in a shocked, two-fluid ADAF accretion disc. The relativistic protons accelerated in the disc escape to power the observed jet outflows. The distribution function for the jet protons is used to compute the TeV emission produced when the jet collides with a cloud or stellar atmosphere. The simulated broadband radiation spectrum includes radio, X-ray, and GeV components generated via synchrotron, as well as TeV emission generated via the production and decay of muons, positrons, and electrons. The self-consistency of the model is verified by computing the relativistic particle pressure using the distribution function, and comparing it with the relativistic particle pressure obtained from the hydrodynamical model. We demonstrate that the model is able to reproduce the multi-wavelength spectrum from M87 observed by VERITAS and HESS during the high-energy flares in 2004, 2005, and 2010.

description: We report on 5.4 yr of phase-coherent timing, using the Rossi X-ray Timing Explorer, of the X-ray pulsar 1RXS 1708-4009, a member of the class known as ``anomalous X-ray pulsars.'' This object exhibited a rotational glitch in 1999. Here we report a second much larger rotational glitch which occured ~1.5 yr after the first. We show that the recoveries from the two glitches are different, with the first showing only a possible slow, approximately linear recovery, while the second showed a nearly complete recovery on a time scale of \~50 days. The approximately exponential recovery time scale of the second glitch is similar to that seen recently in 1E 2259+586 at the time of a major outburst. This suggests 1RXS 1708-4009 undergoes similar bursting behavior, although with our sparse observations we have detected no other evidence for bursts from this source.

description: The lift and drag forces acting on a small, neutrally-buoyant spherical particle in a single-wall-bounded linear shear flow are examined via numerical computation. The effects of shear rate are isolated from those of slip by setting the particle velocity equal to the local fluid velocity (zero slip), and examining the resulting hydrodynamic forces as a function of separation distance. In contrast to much of the previous numerical literature, low shear Reynolds numbers are considered ($10^{-3} \lesssim Re_γ \lesssim 10^{-1}$). This shear rate range is relevant when dealing with particulate flows within small channels, for example particle migration in microfluidic devices being used or developed for the biotech industry. We demonstrate a strong dependence of both the lift and drag forces on shear rate. Building on previous theoretical $Re_γ \ll 1$ studies, a wall-shear based lift correlation is proposed that is applicable when the wall lies both within the inner and outer regions of the disturbed flow. Similarly, we validate an improved drag correlation that includes higher order terms in wall separation distance that more accurately captures the drag force when the particle is close to, but not touching, the wall. Application of the new correlations shows that the examined shear based lift force is as important as the previously examined slip based lift force, highlighting the need to account for shear when predicting the near-wall movement of neutrally-buoyant particles.

description: We study the classical Heisenberg model on a recently identified three dimensional corner-shared equilateral triangular lattice, a magnetic sublattice to a large class of systems with the symmetry group P2$_1$3. Since the degree of geometric frustration of the nearest neighbor antiferromagnetic model on this lattice lies on the border between the pyrochlore (not ordered) and hexagonal (ordered) lattices, it is non-trivial to predict its ground state. Using a classical rotor model, we find an ordered ground state with wavevector $(\frac{2π}{3a_0},0,0)$ featuring 120$^o$ rotated spins on each triangle. However, a mean field approximation on this lattice fails to find an ordered ground state, finding instead a non-trivially degenerate ground state. As the mean field approach is known to agree with Monte Carlo on the pyrochlore lattice, the reasons for this discrepancy are discussed. We also discuss the possible relevance of our results to MnSi.

description: In 2019 October Betelgeuse began a decline in V-band brightness that went beyond the minimum expected from its quasi-periodic ~420 day cycle, becoming the faintest in recorded photometric history. Observations obtained in 2019 December with VLT/SPHERE (Montarges 2020) have shown that the southern half of the star has become markedly fainter than in 2019 January indicating that a major change has occurred in, or near, the photosphere. We present SOFIA-EXES high spectral-resolution observations of [Fe II] 25.99 mic and [S I] 25.25 mic emission lines from Betelgeuse obtained during the unprecedented 2020 February V-band brightness minimum to investigate potential changes in the circumstellar flow. These spectra are compared to observations obtained in 2015 and 2017 when the V magnitude was typical of brighter phases. We find only very small changes in the gas velocities reflected by either of the line profiles, no significant changes in the flux to continuum ratios, and hence no significant changes in the [Fe II]/[S I] flux ratios. There is evidence that absorption features have appeared in the 2020 continuum. The Alfven wave-crossing time from the upper-photosphere is sufficiently long that one would not expect a change in the large scale magnetic field to reach the circumstellar [Fe II] and [S I] line forming regions, 3 < R(R*) < 20. However, the light-crossing time is of order a few hours and a reduction in luminosity may reduce the dust-gas heating rate and [O I] 63.19 mic emission which has contributions from R > 20R*, where significant circumstellar oxygen-rich dust is observed.

description: We propose the use of a self-oscillating dynamical system --the pre-Galileian clock equation-- for modeling the laryngeal tone. The parameters are shown to be the minimal control needed for generating the prosody of the human speech. Based on this model, we outline a peak delay detection algorithm for extracting the prosody of the real speech.

description: A binary lattice gas model that allows for multiple occupancy of lattice sites, inspired by recent coarse-grained descriptions of solutions of interacting polymers, is investigated by combining the steepest descent approximation with an exploration of the multidimensional energy landscape, and by Gibbs ensemble Monte Carlo simulations. The one-component version of the model, involving on site and nearest neighbour interactions, is shown to exhibit microphase separation into two sub-lattices with different mean occupation numbers. The symmetric two-component version of the multiple occupancy lattice gas is shown to exhibit a demixing transition into two phases above a critical mean occupation number.

From Guesstimates to GPStimates : Land Area Measurement and Implications for Agricultural Analysis

description: Development goals and poverty-reduction policies are often focused on raising agricultural productivity and dependent on farm household level data. Historically, household surveys commonly employed self-reported land area measurements for cost-effectiveness and convenience. However, as we illustrate here, these self-reported estimates may measure land with systematic error resulting in sizable biases. This has led to the increased use of Global Positioning Systems (GPS) and other modern technologies to measure land size. In this article, we compare self-reported (SR) and GPS land measurement to assess the differences between the measures, to identify the sources of differences, and to determine the implications of the different measures on agricultural analysis. The results from the analysis of data from four African countries indicate that SR land areas systematically differ from GPS land measures and that this difference leads to biased estimates of the relationship between land and productivity and consistently low estimates of land inequality. Through the evidence and analysis presented here, we conclude that the more systematic use of GPS-measured land area will result in improved agricultural statistics and more accurate analysis of agricultural relationships, which will better inform future policy.

description: We simulate stacked observations of nearby hot X-ray coronae associated with galaxies in the EAGLE and Illustris-TNG hydrodynamic simulations. A forward modeling pipeline is developed to predict 4-year eROSITA observations and stacked image analysis, including the effects of instrumental and astrophysical backgrounds. We propose an experiment to stack z~0.01 galaxies separated by specific star-formation rate (sSFR) to examine how the hot (T>=10^6 K) circumgalactic medium (CGM) differs for high- and low-sSFR galaxies. The simulations indicate that the hot CGM of low-mass (M_*~10^{10.5} Msol), high-sSFR (defined as the top one-third ranked by sSFR) central galaxies will be detectable to a galactocentric radius r~30-50 kpc. Both simulations predict lower luminosities at fixed stellar mass for the low-sSFR galaxies (the lower third of sSFR) with Illustris-TNG predicting 3x brighter coronae around high-sSFR galaxies than EAGLE. Both simulations predict detectable emission out to r~150-200 kpc for stacks centered on high-mass (M_*~10^{11.0} Msol) galaxies, with EAGLE predicting brighter X-ray halos. The extended soft X-ray luminosity correlates strongly and positively with the mass of circumgalactic gas within the virial radius (f_{CGM}). Prior analyses of both simulations have established that f_{CGM} is reduced by expulsive feedback driven mainly by black hole growth, which quenches galaxy growth by inhibiting replenishment of the ISM. Both simulations predict that eROSITA stacks should not only conclusively detect and resolve the hot CGM around L^* galaxies for the first time, but provide a powerful probe of how the baryon cycle operates, for which there remains an absence of consensus between state-of-the-art simulations.

title: Children as Researchers: A Case Study of an Initiative in One Primary School
Creators: name: Jones, Philip Charles
Publisher: name: The Open University
Year: 2016

description: This study describes a research project undertaken in an English primary school with Year 5 children where, over two years, children were trained as researchers and then undertook their own research projects looking into a variety of issues they identified within school. Its practitioner-led nature allows for an examination of the diverse positions I undertook whilst conducting the research: headteacher, teacher, doctoral researcher, co-researcher and supervisor of the children’s research. The research is based upon an interpretivist framework and can be located within the literatures of ‘participation’ and ‘pupil voice’ and, more specifically, ‘children as researchers’. Case study methods are used to both examine and assess the impact and value of the initiative. Through the written recording of observations, structured and unstructured questioning and on-going encounters between me and children, the developing capacity of children as researchers, including their limitations, is described and analysed along with the potential wider benefits. The long-term nature of this study offers a contrast with many similar, short-term, projects allowing data to be collected over time to support the emergent nature of ideas as the study progressed. With a central research question of ‘What happens when children are encouraged to be researchers?’, this case study examines and analyses the children’s responses to the data collection methods used, the data collected, and the presentation of their findings, in order to highlight the conditions required for a successful project; whilst also identifying difficulties. In this respect it offers an insight for other practitioners looking to recreate similar situations. It further highlights the conflicts faced by an insider researcher, the roles and relationships between me and children and between children, both within the research group and with their respondents. The implications are analysed in relation to Foucault’s notion of power, being situated within a complex web of relations, rather than as simply oppositional forces.

description: Abstract: Molecular profiles of neurons influence neural development and function but bridging the gap between genes, circuits, and behavior has been very difficult. Here we used single cell RNAseq to generate a complete gene expression atlas of the Drosophila larval central nervous system composed of 131,077 single cells across three developmental stages (1 h, 24 h and 48 h after hatching). We identify 67 distinct cell clusters based on the patterns of gene expression. These include 31 functional mature larval neuron clusters, 1 ring gland cluster, 8 glial clusters, 6 neural precursor clusters, and 13 developing immature adult neuron clusters. Some clusters are present across all stages of larval development, while others are stage specific (such as developing adult neurons). We identify genes that are differentially expressed in each cluster, as well as genes that are differentially expressed at distinct stages of larval life. These differentially expressed genes provide promising candidates for regulating the function of specific neuronal and glial types in the larval nervous system, or the specification and differentiation of adult neurons. The cell transcriptome Atlas of the Drosophila larval nervous system is a valuable resource for developmental biology and systems neuroscience and provides a basis for elucidating how genes regulate neural development and function.
