Health inequalities in people with intellectual disability
Creators: name: McMahon, Martin
Publisher: name: Lancaster University
Year: 2022

description: Abstract Background: The opportunity for people with intellectual disability to live a long and healthy life is impacted by the conditions into which they are born, grow up and live. This research provides insight into health and non-medical factors that influence health, in a comparative population of people with and without intellectual disability. Aim: To examine the health, objective and subjective socioeconomic status of adults with and without intellectual disability in Jersey. It explores the prevalence of health problems, polypharmacy and drug-drug interactions and the relationships with objective and subjective socioeconomic status on the health of people with an intellectual disability. Methods: An administrative population of 217 adults with, and a random stratified sample of 2,350 adults without, intellectual disability participated in this study. Proxy respondents were used where people did not have capacity to consent. The prevalence, patterns and relationships with health problems, polypharmacy, drug-drug interactions and socioeconomic status are described. Associations of these characteristics were analysed using univariate and multivariate analysis. Findings: People with intellectual disability have poorer health than the general population which starts earlier in life. They are especially vulnerable to the negative effects of taking multiple medications. Adults with intellectual disability also occupy lower socioeconomic status and report lower levels of subjective socioeconomic status and poorer self-rated health than the general population. Higher subjective socioeconomic status and younger age were significant predictors of better self-rated health reported by the proxy intellectual disability group only, while being employed was associated with better health for all populations. Conclusion: Significant efforts are needed to reduce the non-medical factors that influence the health inequalities experienced by adults with intellectual disability. This study underlines the poorer health and adverse impact that multiple medications may have. Equally, it highlights the atypical and lower socioeconomic position that adults with an intellectual disability experience. Further research in larger prospective comparative studies is needed to understand the relationship between subjective socioeconomic status and health in adults with intellectual disability.

description: The existence of quark matter inside the heaviest neutron stars has been the topic of numerous recent studies, many of them suggesting that a phase transition to strongly interacting conformal matter inside neutron stars is feasible. Here we examine this hybrid star scenario using a soft and a stiff hadronic model, a constituent quark model with three quark flavours, and applying a smooth crossover transition between the two. Within a Bayesian framework, we study the effect of up-to-date constraints from neutron star observations on the equation-of-state parameters and various neutron star observables. Our results show that a pure quark core is only possible if the maximum mass of neutron stars is below $\sim2.35~M_\odot$. However, we also find, consistently with other studies, that a peak in the speed of sound, exceeding $1/3$, is highly favoured by astrophysical measurements, which might indicate the percolation of hadrons at $\sim3-4n_0$. Even though our prediction for the phase transition parameters varies depending on the specific astrophysical constraints utilized, the position of the speed of sound peak only changes slightly, while the existence of pure quark matter below $\sim4 n_0$, using our parameterization, is disfavoured. On the other hand, the preferred range for the EoS shows signs of conformality above $\sim4n_0$. Additionally, we present the difference in the upper bounds of radius estimates using the full probability density data and sharp cut-offs, and stress the necessity of using the former.

description: We investigate the existence of solutions $E:\mathbb{R}^3\to\mathbb{R}^3$ of the time-harmonic semilinear Maxwell equation $$\nabla\times(\nabla\times E) + V(x) E = \partial_E F(x,E) \quad \text{in}\mathbb{R}^3,$$ where $V:\mathbb{R}^3\to\mathbb{R}$, $V(x)\leq 0$ a.e. on $\mathbb{R}^3$, $\nabla\times$ denotes the curl operator in $\mathbb{R}^3$ and $F:\mathbb{R}^3\times\mathbb{R}^3\to\mathbb{R}$ is a nonlinear function in $E$. In particular we find a ground state solution provided that suitable growth conditions on $F$ are imposed and $L^{3/2}$-norm of $V$ is less than the best Sobolev constant. In applications $F$ is responsible for the nonlinear polarization and $V(x)=-μω^2\varepsilon(x)$ where $μ>0$ is the magnetic permeability, $ω$ is the frequency of the time-harmonic electric field $\Re\{E(x)e^{iωt}\}$ and $\varepsilon$ is the linear part of the permittivity in an inhomogeneous medium.

The Liquid--Hexatic Transition for Soft Disks

description: We study the liquid--hexatic transition of soft disks with massively parallel simulations and determine the equation of state as a function of system size. For systems with interactions decaying as the inverse $m$th power of the separation, the liquid--hexatic phase transition is continuous for $m = 12$ and $m=8$, while it is of first order for $m = 24$. The critical power $m$ for the transition between continuous and first-order behavior is larger than previously reported. The continuous transition for $ m=12 $ implies that the two-dimensional Lennard-Jones model has a continuous liquid--hexatic transition at high temperatures. We also study the Weeks--Chandler--Andersen model and find a continuous transition at high temperatures, that is consistent with the soft-disk case for $m=12$. Pressure data as well as our implementation are available from an open-source repository.

description: Complex problems often require coordinated group effort and can consume significant resources, yet our understanding of how teams form and succeed has been limited by a lack of large-scale, quantitative data. We analyze activity traces and success levels for ~150,000 self-organized, online team projects. While larger teams tend to be more successful, workload is highly focused across the team, with only a few members performing most work. We find that highly successful teams are significantly more focused than average teams of the same size, that their members have worked on more diverse sets of projects, and the members of highly successful teams are more likely to be core members or 'leads' of other teams. The relations between team success and size, focus and especially team experience cannot be explained by confounding factors such as team age, external contributions from non-team members, nor by group mechanisms such as social loafing. Taken together, these features point to organizational principles that may maximize the success of collaborative endeavors.

description: The quantum dynamics of spin systems with uniform all-to-all interaction are often studied in the totally symmetric space (TSS) of maximal total spin. However the TSS states are atypical in the full many-body Hilbert space. In this work, we explore several aspects of the all-to-all quantum dynamics away from the TSS, and reveal surprising features of the "deep Hilbert space" (DHS). We study the out-of-time order correlator (OTOC) in the infinite-temperature ensemble of the full Hilbert space. We derive a phase-space representation of the DHS OTOC and show that the OTOC can grow super-exponentially in the large $N$ limit, due to the fast dynamics in an unbounded phase space (in finite systems, we observe numerically that the super-exponential growth ends precociously and gives way to a power-law one until saturation). By a similar mechanism, the Krylov complexity grows explosively. We also study the entanglement growth in a quantum quench from a DHS product state, i.e., one of non-aligned spins that resemble the DHS infinite-temperature ensemble with respect to the statistics of the collective spins. Using a field-theoretical method, We exactly calculate the entanglement entropy in the large $N$ limit. We show that, in the DHS, fast OTOC growth does not imply fast entanglement growth, in contrast to the Zurek-Paz relation derived in the TSS.

Le travail présente les enjeux du mécanisme du bouc émissaire : comment il se crée, comment il se développe et les raisons de sa perpétuelle existence. Cette présentation du sujet est axée autour du travail de l’écrivain René Girard, qui a fait beaucoup d’études et de recherches sur le sujet. Par la suite, de manière plus pratique, ce travail relate des témoignages, anonymes, de vécus sur le terrain. Dans le premier témoignage, un ancien élève, qui était bouc émissaire de sa classe, explique son expérience en tant que victime, comment il l’a vécue et quelles ont été les conséquences sur son futur. Le second témoignage est donné par une enseignante qui avait un bouc émissaire dans la classe où elle enseignait. Elle explique quelles ont été les conséquences sur l’apprentissage des élèves et sur l’atmosphère dans la classe. Ce mémoire offre ensuite une analyse de ces témoignages aux vues des apports théoriques. Plus particulièrement, il analyse en quoi les mécanismes du bouc émissaire affectent les apprentissages des élèves. Des citations tirées de divers livres, qui concernent ces phénomènes de violences et de discipline en classe, notamment des récits d’enseignement, viennent illustrer plus en profondeur les enjeux autour du bouc émissaire. Finalement, ce document fournit, aux enseignants, des pistes d’action pour palier l’engrenage des mécanismes de violence dans la classe, afin de permettre aux élèves d’étudier dans une ambiance de classe positive.

description: The field of radio astronomy is witnessing a boom in the amount of data produced per day due to newly commissioned radio telescopes. One of the most crucial problems in this field is the automatic classification of extragalactic radio sources based on their morphologies. Most recent contributions in the field of morphological classification of extragalactic radio sources have proposed classifiers based on convolutional neural networks. Alternatively, this work proposes gradient boosting machine learning methods accompanied by principal component analysis as data-efficient alternatives to convolutional neural networks. Recent findings have shown the efficacy of gradient boosting methods in outperforming deep learning methods for classification problems with tabular data. The gradient boosting methods considered in this work are based on the XGBoost, LightGBM, and CatBoost implementations. This work also studies the effect of dataset size on classifier performance. A three-class classification problem is considered in this work based on the three main Fanaroff-Riley classes: class 0, class I, and class II, using radio sources from the Best-Heckman sample. All three proposed gradient boosting methods outperformed a state-of-the-art convolutional neural networks-based classifier using less than a quarter of the number of images, with CatBoost having the highest accuracy. This was mainly due to the superior accuracy of gradient boosting methods in classifying Fanaroff-Riley class II sources, with 3$\unicode{x2013}$4% higher recall.

description: On-surface metal porphyrins can undergo electronic and conformational changes that play a crucial role in determining the chemical reactivity of the molecular layer. Therefore, understanding those properties is pivotal for the design and implementation of organic-based devices. Here, by means of photoemission orbital tomography supported by density functional theory calculations, we investigate the electronic and geometrical structure of two metallated tetraphenyl porphyrins (MTPPs), namely ZnTPP and NiTPP, adsorbed on the oxygen-passivated Fe(100)-p(1x1)O surface. Both molecules weakly interact with the surface as no charge transfer is observed. In the case of ZnTPP our data correspond to those of moderately distorted molecules, while NiTPP exhibits a severe saddle-shape deformation. From additional experiments on NiTPP multilayer films, we conclude that this distortion is a consequence of the interaction with the substrate, as the NiTPP macrocycle of the second layer turns out to be flat. We further find that distortions in the MTPP macrocycle are accompanied by an increasing energy gap between the highest occupied molecular orbitals (HOMO and HOMO-1). Our results demonstrate that photoemission orbital tomography can simultaneously probe the energy level alignment, the azimuthal orientation, and the adsorption geometry of complex aromatic molecules even in the multilayer regime.

These algebras can be regarded as coideal subalgebras of the extended Yangian for orthogonal or symplectic Lie algebras. They can also be presented as quotients of a reflection algebra by additional symmetry relations. We prove an analogue of the Poincare-Birkoff-Witt Theorem, determine their centres and study also extended reflection algebras.

description: We predict a universal echo phenomenon present in the time evolution of many-body states of interacting quantum systems described by Fermi-Hubbard models. It consists of the coherent revival of transition probabilities echoing a sudden flip of the spins that, contrary to its single-particle (Hahn) version, is not dephased by interactions or spin-orbit coupling. The many-body spin echo signal has a universal shape independent of the interaction strength, and an amplitude and sign depending only on combinatorial relations between the number of particles and the number of applied spin flips. Our analytical predictions, based on semiclassical interfering amplitudes in Fock space associated with chaotic mean-field solutions, are tested against extensive numerical simulations confirming that the coherent origin of the echo lies in the existence of anti-unitary symmetries.

description: Architects and engineers around the world want to explore the use of mass-timber as a structural material in buildings due to its perceived advantages as a natural and pre-manufactured material. Mass-timber members are however combustible and therefore can influence fire dynamics in a compartment and alter the resulting structural fire severity when compared to non-combustible compartments. Additionally, knowledge from the fire dynamics of open-plan non-combustible compartments has shown that there are different phenomena from those observed in smaller compartments. Fire dynamics in open-plan compartments with an exposed timber ceiling were recently explored in the CodeRed experiments [1]–[3]. This work aims to extend previous work by presenting the lessons learnt from the CodeRed series of experiments on the structural fire severity of open-plan compartments with an exposed timber ceiling. The time equivalence results for structural members included within the experiments, will be presented for the first time based on the observed charring depth of the exposed CLT ceiling and glulam columns, and the observed temperatures of the protected steel column.
Dynamical friction and feedback on galactic bars in the general fast-slow regime

Publisher: name: arXiv
Year: 2023
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Current theories of dynamical friction on galactic bars are based either on linear perturbation theory, which is valid only in the fast limit where the bar changes its pattern speed rapidly, or on adiabatic theory, which is applicable only in the slow limit where the bar's pattern speed is near-constant. In this paper, we study dynamical friction on galactic bars spinning down at an arbitrary speed, seamlessly connecting the fast and slow limits. We treat the bar-halo interaction as a restricted $N$-body problem and solve the collisionless Boltzmann equation using the fast-angle-averaged Hamiltonian. The phase-space distribution and density wakes predicted by our averaged model are in excellent agreement with full 3D simulations. In the slow regime where resonant trapping occurs, we show that, in addition to the frictional torque, angular momentum is transferred directly due to the migration of the trapped phase-space: trapped orbits comoving with the resonance typically gain angular momentum, while untrapped orbits leaping over the trapped island lose angular momentum. Due to the negative gradient in the distribution function, gainers typically outnumber the losers, resulting in a net negative torque on the perturber. Part of this torque due to the untrapped orbits was already identified by Tremaine & Weinberg who named the phenomenon dynamical feedback. Here, we derive the complete formula for dynamical feedback, accounting for both trapped and untrapped orbits. Using our revised formula, we show that dynamical feedback can account for up to $30\%$ of the total torque on the Milky Way's bar.

description: With an action $α$ of $\mathbb{R}^n$ on a $C^*$-algebra $A$ and a skew-symmetric $n\times n$ matrix $Θ$ one can consider the Rieffel deformation $A_Θ$ of $A$, which is a $C^*$-algebra generated by the $α$-smooth elements of $A$ with a new multiplication. The purpose of this paper is to obtain explicit formulas for $K$-theoretical quantities defined by elements of $A_Θ$. We assume that there is a densely defined trace on $A$, invariant under the action. We give an explicit realization of Thom class in $KK$ in any dimension $n$, and use it in the index pairings. When $n$ is odd, for example, we give a formula for the index of operators of the form $Pπ^Θ(u)P$, where $π^Θ(u)$ is the operator of left Rieffel multiplication by an invertible element $u$ over the unitization of $A$, and $P$ is projection onto the nonnegative eigenspace of a Dirac operator constructed from the action $α$. The results are new also for the undeformed case $Θ=0$. The construction relies on two approaches to Rieffel deformations in addition to Rieffel's original one: "Kasprzak deformation" and "warped convolution". We end by outlining potential applications in mathematical physics.

description: We describe a method based on the CL$_s$ approach to present results in searches of new physics, under the condition that the relevant parameter space is continuous. Our method relies on a class of test statistics developed for non-nested hypotheses testing problems, denoted by $ΔT$, which has a Gaussian approximation to its parent distribution when the sample size is large. This leads to a simple procedure of forming exclusion sets for the parameters of interest, which we call the Gaussian CL$_s$ method. Our work provides a self-contained mathematical proof for the Gaussian CL$_s$ method, that explicitly outlines the required conditions. These conditions are milder than that required by the Wilks' theorem to set confidence intervals (CIs). We illustrate the Gaussian CL$_s$ method in an example of searching for a sterile neutrino, where the CL$_s$ approach was rarely used before. We also compare data analysis results produced by the Gaussian CL$_s$ method and various CI methods to showcase their differences.

description: Empirical data on the dynamics of human face-to-face interactions across a variety of social venues have recently revealed a number of context-independent structural and temporal properties of human contact networks. This universality suggests that some basic mechanisms may be responsible for the unfolding of human interactions in the physical space. Here we discuss a simple model that reproduces the empirical distributions for the individual, group and collective dynamics of face-to-face contact networks. The model describes agents that move randomly in a two-dimensional space and tend to stop when meeting "attractive" peers, and reproduces accurately the empirical distributions.

description: More than 60 years after the discovery of the Roman villa of Bocca delle Menate in Comacchio (FE) (I-II century AD), the University of Ferrara has undertaken an archaeological survey on the site. Despite the Villa was buried after the discovery, from the ground are still emerging several findings. The aim of the archeological project was to verify the site preservation conditions on behalf of the VALUE-enVironmental and cuLtUral hEritage development project for the enhancement of the local archaeological sites. Implementing the previous studies of the archeological materials found in the 50s emergency excavations, the contribution analyzes the two most represented ceramic assemblages collected during the survey: transport containers and building materials. Despite the extremely fragmented state, the analyzed findings have returned numerous confirmations and new data. The focus of the presentation is on the production centers of amphorae and building materials to outline the territorial network, trade flows and local productive sources. The Adriatic productive centers are the most documented despite few containers from the Tyrrhenian side and from the provinces of the Mediterranean region are recorded. Brick stamps of minor private workshops within the well-known Pansiana and Solonas provide a new documentation of the villa’s local short and medium-range network, especially with the Regio VIII Aemilia and the Regio X Venetia et Histria.

description: ABSTRACT: Drawing from a range of her prose, poetic, and theological work, this article focuses on four recurring themes in Sor Juana’s philosophy: a socially situated picture of knowledge production, the social construction of gender, a limited form of skepticism about revisionist theology, and the idea of obedience and self-control. Her treatment of these issues suggests a potentially systematic picture we might call social fallibilism, that is, the view that what we know and can do are dependent on somewhat fragile features of both agents and social and material contexts. It is a prescient picture of human agency, where central features—including freedom and knowledge—are always relational in their realization and subject to failure.

description: We introduce concepts from optimal estimation to the stabilization of precision frequency standards limited by noisy local oscillators. We develop a theoretical framework casting various measures for frequency standard variance in terms of frequency-domain transfer functions, capturing the effects of feedback stabilization via a time-series of Ramsey measurements. Using this framework we introduce a novel optimized hybrid predictive feedforward measurement protocol which employs results from multiple past measurements and transfer-function-based calculations of measurement covariance to improve the accuracy of corrections within the feedback loop. In the presence of common non-Markovian noise processes these measurements will be correlated in a calculable manner, providing a means to capture the stochastic evolution of the LO frequency during the measurement cycle. We present analytic calculations and numerical simulations of oscillator performance under competing feedback schemes and demonstrate benefits in both correction accuracy and long-term oscillator stability using hybrid feedforward. Simulations verify that in the presence of uncompensated dead time and noise with significant spectral weight near the inverse cycle time predictive feedforward outperforms traditional feedback, providing a path towards developing a new class of stabilization "software" routines for frequency standards limited by noisy local oscillators.

Brownian hitting distributions in space-time of bounded sets and the expected volume of Wiener sausage for Brownian bridges

description: The space-time distribution, $Q_A(x,dt dξ)$ say, of Brownian hitting of a bounded Borel set $A$ of the $d$-dimensional Euclidian space is studied. We derive the asymptotic form of the leading term of the time-derivative $Q_A(x, dtdξ)/dt$ for each $d =2, 3, ...$, valid uniformly with respect to the starting point $x$ of the Brownian motion, which result extends significantly the classical results for $Q_A(x, dt dξ)$ itself by Hunt ($d=2$), Joffe and Spitzer ($d= 3, 4,...$). The results are applied to find the asymptotic form of the expected volume of Wiener sausage for the Brownian bridge joining the origin to a distant point.

description: This In Brief captures the general perceptions and mood of a sample of Papua New Guineans during the state of emergency (SOE) imposed due to the COVID-19 pandemic in Papua New Guinea (PNG). A short questionnaire was sent to 19 Papua New Guineans using an online survey platform (Survey Monkey) during the height of the lockdown in mid-2020. This In Brief describes some of the measures taken by the PNG government in response to the pandemic and, through the survey, offers insights into the impact of the pandemic on citizens and how they interpreted the government’s measures.

description: We present the application of a fluctuating hydrodynamic theory to study current fluctuations in diffusive systems on a semi-infinite line in contact with a reservoir with slow coupling. We show that the distribution of the time-integrated current across the boundary at large times follows a large deviation principle with a rate function that depends on the coupling strength with the reservoir. The system exhibits a long-term memory of its initial state, which was earlier reported on an infinite line and can be described using quenched and annealed averages of the initial state. We present an explicit expression of the rate function for independent particles, which we verify using an exact solution of the microscopic dynamics. For the symmetric simple exclusion process, we present expressions for the first three cumulants of both quenched and annealed averages.

description: We discuss the rigidity (or lack thereof) imposed by different notions of having an abundance of zero curvature planes on a complete Riemannian 3-manifold. We prove a rank rigidity theorem for complete 3-manifolds, showing that having higher rank is equivalent to having reducible universal covering. We also study 3-manifolds such that every tangent vector is contained in a flat plane, including examples with irreducible universal covering, and discuss the effect of finite volume and real-analiticity assumptions.

description: The proliferation of in-the-wild videos has greatly expanded the Video Quality Assessment (VQA) problem. Unlike early definitions that usually focus on limited distortion types, VQA on in-the-wild videos is especially challenging as it could be affected by complicated factors, including various distortions and diverse contents. Though subjective studies have collected overall quality scores for these videos, how the abstract quality scores relate with specific factors is still obscure, hindering VQA methods from more concrete quality evaluations (e.g. sharpness of a video). To solve this problem, we collect over two million opinions on 4,543 in-the-wild videos on 13 dimensions of quality-related factors, including in-capture authentic distortions (e.g. motion blur, noise, flicker), errors introduced by compression and transmission, and higher-level experiences on semantic contents and aesthetic issues (e.g. composition, camera trajectory), to establish the multi-dimensional Maxwell database. Specifically, we ask the subjects to label among a positive, a negative, and a neutral choice for each dimension. These explanation-level opinions allow us to measure the relationships between specific quality factors and abstract subjective quality ratings, and to benchmark different categories of VQA algorithms on each dimension, so as to more comprehensively analyze their strengths and weaknesses. Furthermore, we propose the MaxVQA, a language-prompted VQA approach that modifies vision-language foundation model CLIP to better capture important quality issues as observed in our analyses. The MaxVQA can jointly evaluate various specific quality factors and final quality scores with state-of-the-art accuracy on all dimensions, and superb generalization ability on existing datasets.

description: Ce travail s’interroge sur la façon de motiver une population d’apprenti·e·s à l’aide d’outils MITIC. L’approche la plus souvent citée pour favoriser la motivation des élève est la pédagogie de projet. Par le questionnement métacognitif et méthodologique qu’il suppose, le processus de projet révèle pour les élèves le sens donné à leurs apprentissages. Les compétences numériques des élèves constituent un moyen privilégié pour mettre en oeuvre cette pédagogie et par là, de motiver les élèves. La pédagogie de projet est elle-même la façon la plus adéquate pour exercer ces compétences indispensables à la formation professionnelle des élèves ainsi que les autres aptitudes visées par leur plan d’études.

description: Generalizing Dollard's strategy, we investigate the structure of the scattering theory associated to any large time reference dynamics $U_D(t)$ allowing for the existence of Møller operators. We show that (for each scattering channel) $U_D(t)$ uniquely identifies, for $t \to \pm \infty$, {\em asymptotic dynamics} $U_\pm(t)$; they are unitary {\em groups} acting on the scattering spaces, satisfy the Møller interpolation formulas and are interpolated by the $S$-matrix. In view of the application to field theory models, we extend the result to the adiabatic procedure. In the Heisenberg picture, asymptotic variables are obtained as LSZ-like limits of Heisenberg variables; their time evolution is induced by $U_\pm(t)$, which replace the usual free asymptotic dynamics. On the asymptotic states, (for each channel) the Hamiltonian can by written in terms of the asymptotic variables as $H = H_\pm (q_{out/in}, p_{out/in})$, $ H_\pm (q,p) $ the generator of the asymptotic dynamics. As an application, we obtain the asymptotic fields $ψ_{out/in}$ in repulsive Coulomb scattering by an LSZ modified formula; in this case, $U_\pm(t)= U_0(t)$, so that $ψ_{out/in}$ are \emph{free} canonical fields and $H = H_0(ψ_{out/in})$.

A Cosmogram of Its Time - A Conceptual Analysis of the Catalan Atlas
Creators: name: Mariani, Benedetta
Publisher: name: Sezione di Storia e Scienze dell'Antichità
Year: 2022

description: This article aims to evaluate the role of maps in the Middle Ages and to assess whether they should be understood uniquely as antique geographical tools or, rather, as important historic records of a certain-time culture. Thus, the concept of cosmogram is applied to a specific case-study, the medieval portolan chart known as Catalan Atlas. The paper challenges what makes a map a complete and tangible representation of the understanding of the world at a specific moment, as opposed to a “simple” instrument to navigate the physical environment. In addition, the whole concept of medieval maps being just orientational aids will be put under pressure, comparing the Catalan Atlas with another medieval map, the Peutinger Tabula. Ultimately, it demonstrates that any map, even a contemporary one, always presents a degree of interpretation in the way it may mirror the historic context in which it was produced.
