description: We show that belief propagation combined with ordered statistics post-processing is a general decoder for quantum low density parity check codes constructed from the hypergraph product. To this end, we run numerical simulations of the decoder applied to three families of hypergraph product code: topological codes, fixed-rate random codes and a new class of codes that we call semi-topological codes. Our new code families share properties of both topological and random hypergraph product codes, with a construction that allows for a finely-controlled trade-off between code threshold and stabilizer locality. Our results indicate thresholds across all three families of hypergraph product code, and provide evidence of exponential suppression in the low error regime. For the Toric code, we observe a threshold in the range $9.9\pm0.2\%$. This result improves upon previous quantum decoders based on belief propagation, and approaches the performance of the minimum weight perfect matching algorithm. We expect semi-topological codes to have the same threshold as Toric codes, as they are identical in the bulk, and we present numerical evidence supporting this observation.

The Shadow of the Myth. "El Romancero de Edipo" with Toni Cots Directed by Eugenio Barba (1984-1990)
Creators: name: Mancini, Leonardo
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2021

description: The article focuses on the solo performance El Romancero de Edipo, created by Eugenio Barba together with the Spanish actor Toni Cots, and staged in several countries between 1984 to 1990. The performance was the very first monologue directed by Barba in his long-standing career. For Barba, it was also the first direct approach to the tragic myth, following an interest already cultivated around the figure of Antigone from the early Eighties onwards, in a moment of crisis and need for renewal for the groups of the “Third Theatre” movement, defined by Barba in 1976. For Cots, the monologue was the last and culminating part of his almost ten-year experience as an actor at the Odin Teatret, where he had also developed a personal actor’s training technique (in part based on Balinese traditional dances) and had accompanied Barba through the first research activities in the new field of Theatre Anthropology. With El Romancero of Edipo, Barba explored the tragic myth and elaborated an original theatrical narration based on the creative process of the actor, within which lay the rhythm of the montage. The text was therefore sustained by a rigorous score by the actor and by a detailed line of physical and vocal actions, making use of simple but very effective scenic props such as a vase, a self-built mask, drapery, a wig, and a stick. In addition, the use of songs and melodies, as well as other literary sources, extended the performative language of the artwork, giving life to an innovative reelaboration rich in transcultural influences. By analysing all these elements, the article ‘deconstructs’ the performance, retracing its sources and its development between the actor and the director.

description: We discuss a simple analytical model of the turbulent boundary layer (TBL) over flat plane. The model offers an analytical description of the profiles of mean velocity and turbulent activity in the entire boundary region, from the viscous sub-layer, through the buffer layer further into the log-law turbulent region. In contrast to various existing interpolation formulas the model allows one to generalize the description of simple TBL of a Newtonian fluid for more complicated flows of turbulent suspensions laden with heavy particles, bubbles, long-chain polymers, to include the gravity acceleration, etc.

description: The average predictability (aka informativity) of a word in context has been shown to condition word duration (Seyfarth, 2014). All else being equal, words that tend to occur in more predictable environments are shorter than words that tend to occur in less predictable environments. One account of the informativity effect on duration is that the acoustic details of probabilistic reduction are stored as part of a word's mental representation. Other research has argued that predictability effects are tied to prosodic structure in integral ways. With the aim of assessing a potential prosodic basis for informativity effects in speech production, this study extends past work in two directions; it investigated informativity effects in another large language, Mandarin Chinese, and broadened the study beyond word duration to additional acoustic dimensions, pitch and intensity, known to index prosodic prominence. The acoustic information of content words was extracted from a large telephone conversation speech corpus with over 400,000 tokens and 6,000 word types spoken by 1,655 individuals and analyzed for the effect of informativity using frequency statistics estimated from a 431 million word subtitle corpus. Results indicated that words with low informativity have shorter durations, replicating the effect found in English. In addition, informativity had significant effects on maximum pitch and intensity, two phonetic dimensions related to prosodic prominence. Extending this interpretation, these results suggest that predictability is closely linked to prosodic prominence, and that the lexical representation of a word includes phonetic details associated with its average prosodic prominence in discourse. In other words, the lexicon absorbs prosodic influences on speech production.

description: The mining boom in Australia since 2003 has produced significant economic benefits for regional, State and National economies, creating new job opportunities and revenue flows. Despite the contribution of the resources sector to economic growth, questions are frequently raised about the concomitant negative social, economic and environmental impacts. The Surat Basin in southern Queensland is a traditional agricultural region with a small but growing coal mining sector and a rapidly developing liquefied natural gas industry (mainly associated with extracting coal seam gas). In this paper, the preferences of residents in Brisbane, the State capital, are explored in relation to the relative importance of social, economic and environmental impacts of the resource boom in the Surat Basin. A choice modelling experiment was conducted to assess the trade-offs Brisbane residents would make (in monetary terms) between the economic benefits and the associated costs of increased mining activity on local communities. The results identify the strength of concerns about community and environmental impacts and can potentially be used to help evaluate the net benefits of resource development.

Different effects such as the magnetic field, the quantum dot size, the temperature as well as the electric field on the spin relaxation time are investigated in detail. Moreover, we show that the perturbation method widely used in the literature is inadequate in accounting for the electron structure and therefore the spin relaxation time.

A copula-based approach to the simultaneous estimation of group and meta-frontiers by constrained maximum likelihood

description: Existing approaches to the meta-frontier estimation consist of two stages where the estimates of the local frontier parameters obtained in the first step are used to estimate meta-frontier parameters by means of a linear or quadratic minimisation procedure in the second. Since it was shown by Schmidt (Review of Economics and Statistics 58: 238) that the second step is equivalent to constrained maximisation of a likelihood function, we extend this idea and offer a copula-based approach to the estimation of the parameters of both meta- and group frontiers in a one-step setting. In this way, we ensure a single data-generating mechanism for the estimated parameters, expand the set of potential meta-frontiers and account for the fact that shocks to the individual production units may be correlated with shocks to the local technological environment as a whole. We apply our estimation methodology to a data set on the world agriculture and find that the deviations from the group frontiers are positively correlated with deviations from the meta-frontier, which is a conclusion that is impossible to reach without accounting for stochastic dependence between the two deviation types represented by a copula.

description: In this article we explore a non-abelian torsion theory in the category of preordered groups: the objects of its torsion-free subcategory are the partially ordered groups, whereas the objects of the torsion subcategory are groups (with the total order). The reflector from the category of preordered groups to this torsion-free subcategory has stable units, and we prove that it induces a monotone-light factorization system. We describe the coverings relative to the Galois structure naturally associated with this reflector, and explain how these coverings can be classified as internal actions of a Galois groupoid. Finally, we prove that in the category of preordered groups there is also a pretorsion theory, whose torsion subcategory can be identified with a category of internal groups. This latter is precisely the subcategory of protomodular objects in the category of preordered groups, as recently discovered by Clementino, Martins-Ferreira, and Montoli.

description: This study examines the impact of cool season grass quality characteristics on pricing and net returns in niche equine feed markets. A hedonic analysis of Timothy grass hay prices in Nevada was performed to determine the implicit values of its quality characteristics. A Monte Carlo simulation was then conducted to estimate the distribution of net returns to improving grass hay quality characteristics. Results show that the presence of foreign matter had the largest impact on grass hay price, followed by seller reputation and hay color. However, for risk-averse producers, enhancing seller reputation and grass hay color are the preferred strategies for increasing net returns.
True Order of Versifying. The Reform of Elizabethan Poetry
Creators: name: Orgel, Stephen
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2021

description: For a few decades in the sixteenth century, attempts were made to refashion English verse, as the Romans had refashioned theirs, according to the quantitative system of Greek poetry. The project now seems totally out of touch with the nature of the language and thus doomed to failure, but devising a system of quantitative poetry in English was a project that major poets and critics took seriously. Sir Philip Sidney wrote a good deal of quantitative verse, and Spenser and Gabriel Harvey discussed it and exchanged examples. Abraham Fraunce wrote notably successful poetry in classical meters; the volumes were popular and sold well. The larger assumption behind the proposals for the reform of English poetry was that the ‘barbarous’ England of the time could be rectified by the application of classical rules. A return to the classics held out the promise of culture and civility – not only in poetry, of course, but poetry seemed a particularly clear example. Nobody thought the transformation would be easy; a hectoring and bullying tone is common throughout the discussion. But a good deal of energy in the Elizabethan age went into the devising of strategies for becoming the new ancients, strategies of translation and adaptation, and the invention of appropriately classical-sounding models for vernacular verse, the domestication of the classic.

description: Prices transmit information regarding the underlying quality of a product; when quality is unknown to both buyers and sellers, theory predicts that the same price should be charged for all products. However, in the Thoroughbred industry, difference fees are charged to breed to freshman sires, which are stallions of unknown quality standing their first season at stud. We find that stallion owners/ managers differentiate their products according to attributes which may predict offspring quality. A freshman sire’s own racetrack performance, standing in the state of Kentucky, and descending from a prominent sire line are found to be statistically and economically significant.
Skeleton-based Action Recognition via Spatial and Temporal Transformer Networks

description: Skeleton-based Human Activity Recognition has achieved great interest in recent years as skeleton data has demonstrated being robust to illumination changes, body scales, dynamic camera views, and complex background. In particular, Spatial-Temporal Graph Convolutional Networks (ST-GCN) demonstrated to be effective in learning both spatial and temporal dependencies on non-Euclidean data such as skeleton graphs. Nevertheless, an effective encoding of the latent information underlying the 3D skeleton is still an open problem, especially when it comes to extracting effective information from joint motion patterns and their correlations. In this work, we propose a novel Spatial-Temporal Transformer network (ST-TR) which models dependencies between joints using the Transformer self-attention operator. In our ST-TR model, a Spatial Self-Attention module (SSA) is used to understand intra-frame interactions between different body parts, and a Temporal Self-Attention module (TSA) to model inter-frame correlations. The two are combined in a two-stream network, whose performance is evaluated on three large-scale datasets, NTU-RGB+D 60, NTU-RGB+D 120, and Kinetics Skeleton 400, consistently improving backbone results. Compared with methods that use the same input data, the proposed ST-TR achieves state-of-the-art performance on all datasets when using joints' coordinates as input, and results on-par with state-of-the-art when adding bones information.

“Ex uariis metri generibus”: Two ‘Metrical’ Neo-Latin Translators of Greek Tragedy across the English Channel
Creators: name: Vedelago, Angelica
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2021

description: Among the corpus of Neo-Latin drama, translations from Greek tragedy are an interesting area of inquiry for the study of Neo-Latin metre, as translators are poised between Greek and Latin metrical patterns. Following Continental models such as Erasmus, two sixteenth-century playwrights from the British Isles, George Buchanan and Thomas Watson, undertook the translation of Greek tragedies and were confronted with their metrical complexity, particularly in the choruses. However, thanks to the prosodic education which they received at local grammar schools and at university and which they later perfected on the Continent, Buchanan and Watson were able not only to understand but also to try and reproduce the metre of the Greek original in their Neo-Latin versions, which in different ways deserve the definition of ‘metrical translations’. Moreover, since their plays were conceived for an educational context and meant to be performed by students, Buchanan and Watson’s handling of metre was in all likelihood conditioned by didactic aims.

description: We examine the role that habit plays when producers determine their hedge ratio. Data were collected from U.S. cotton growers in which they indicated their hedging position in 2001 and 2002 as well as their perceived profitability, land ownership structure, and income. To account for heterogeneity, a generalized mixture regres- sion model is used to identify the influence of the determinants of the hedge ratio. Our results identified two segments. In the smaller segment, consisting of 35% of the producers, habit did not affect the hedge ratio; instead, land ownership and perceived profitability were most influential. In the larger segment, consisting of 65% of the producers, the hedge ratio was solely driven by habit. The results show the important role of habit formation in understanding producers’ employed hedge ratio, confirm the importance of heterogeneity, and strengthen the relation- ship between financial structure and market-risk mitigating behavior.
Normal Non-Fluency and Verbatim Theatre: a Linguistic and Performative Analysis
Creators: name: Fois, Eleonora
name: Virdis, Daniela Francesca
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2021

description: The main inspiration for developing a creative verbatim theatre performance is the recording of members of a community, highlighting the claim that the interviewees’ exact words are entirely preserved so that the audience knows it is an authentic word-for-word account. While the common non-fluency features that characterize everyday speech abound in the language of verbatim theatre, the conventions of a theatrical script are strictly connected to their embodiment in performance, so some dramatic transformations are inevitable. The role of playwrights and actors in a genre which seemingly binds and limits them will be investigated through a linguistic and performative analysis of normal non-fluency features in The Laramie Project (2000), a verbatim play by Moisés Kaufman, in which such features are expected to feature prominently, and in Fleabag (2013), a non-verbatim play by Phoebe Waller-Bridge, in which their occurrence would presumably be more limited. The two plays provide a similar background to the investigation of normal non-fluency. The spartan set and the simplicity of costumes and props manage to create an informal and intimate theatrical experience in both The Laramie Project and Fleabag. The two plays are built around the revelation of people’s deepest desires and the confessions of their private thoughts; moreover, they both employ the technique of directly addressing the audience in the performance in order to develop an emotional connection with them. Our analysis of normal non-fluency will be grounded in plays belonging to different genres but with a common purpose and a common dialogical structure. By contrasting the scripts of the two texts and the transcriptions of their performances, the analysis aims to bring to light the complexity of the notion and interpretation of ‘verbatim’. It does so by examining the occurrences of normal non-fluency and exploring the performative function of omissions or additions. Keywords: verbatin theatre; normal non-fluency; The Laramie Project; Fleabag; linguistic analysis; performative analysis

description: As is well known, classical General Relativity does not constrain the topology of the spatial sections of our Universe. However, the Brane-World approach to cosmology might be expected to do so, since in general any modification of the topology of the brane must be reflected in some modification of that of the bulk. Assuming the truth of the Adams-Polchinski-Silverstein conjecture on the instability of non-supersymmetric AdS orbifolds, evidence for which has recently been accumulating, we argue that indeed many possible topologies for accelerating universes can be ruled out because they lead to non-perturbative instabilities.

Exact diagonalization of the model is performed by introducing a notion of quasiparticles.

description: We develop a method for estimating the instantaneous lift coefficient on a rapidly pitching airfoil that uses a small number of pressure sensors and a measurement of the angle of attack. The approach assimilates four surface pressure measurements with a modified nonlinear state space model (Goman-Khrabrov model) through a Kalman filter. The error of lift coefficient estimates based only on a weighted-sum of the measured pressures are found to be noisy and biased, which leads to inaccurate estimates. The estimate is improved by including the predictive model in an conventional Kalman filter. The Goman-Khrabrov model is shown to be a linear parameter-varying system and can therefore be used in the Kalman filter without the need for linearization. Additional improvement is realized by modifying the algorithm to provide more accurate estimate of the lift coefficient. The improved Kalman filtering approach results in a bias-free lift coefficient estimate that is more precise than either the pressure-based estimate or the Goman-Khrabrov model on their own. The new method will enable performance enhancements in aerodynamic systems whose performance relies on lift.
Mechanisms underlying the downregulation of the transporter associated with antigen processing (TAP)-1 in carcinomas
Creators: name: Setiadi, Alvernia Francesca
Publisher: name: University of British Columbia
Year: 2011

description: Expression of Transporter associated with Antigen Processing (TAP)-1 is often lost in metastatic carcinomas, resulting in defective antigen processing and presentation, and escape of the cancer cell from immune surveillance. In this study, the nature of TAP-1 deficiencies in tumors was investigated. By chromatin immunoprecipitation assay, it was shown that the recruitment of RNA polymerase II to the Tap-1 gene was impaired in TAP-deficient, metastatic cells derived from murine melanoma, prostate and lung carcinomas. Levels of TAP-1 promoter activity, as assessed by stable transfections with a reporter construct containing the TAP-1 promoter, were also relatively low in TAP-deficient cells. These suggest that the deficiency in TAM expression resulted--at least partially--from a reduced level of transcriptional activity of the Tap-1 gene. In order to examine genetic heritability of regulators of TAP-1 promoter activity, TAP- and MHC class I-deficient cells of H-2[sup b] origin were fused with wild-type fibroblasts of H-2[sup k] origin. Fusion with TAP-expressing cells complemented the low levels of TAP-1 promoter activity in TAP-deficient cells. However, these fused cells exhibited lower levels of TAP-1 mRNA and H-2[sup k] than unfused fibroblasts. Further analysis showed that TAP-1 mRNA stability was lower in fused carcinoma-fibroblasts than in unfused fibroblasts. Taken together, TAP deficiency in many carcinomas appears to be caused by a decrease in activity/expression of trans-acting factors regulating TAP-1 promoter activity, as well as a decrease in TAP-1 mRNA stability. The hypothesis that epigenetic regulation plays a fundamental role in controlling TAP-1 transcription was also tested. Chromatin immunoprecipitation analyses showed that the lack of TAP-1 transcription correlated with low levels of recruitment of a histone acetyltransferase, CBP, and of histone H3 acetylation at the TAP-1 promoter, leading to a decrease in accessibility of the RNA polymerase II complex to the TAP-1 promoter. These findings lie at the heart of understanding immune escape mechanisms in tumors and suggest that the reversal of epigenetic codes may provide novel immunotherapeutic paradigms for intervention in cancer.

description: We argue that conformal invariance is a common thread linking several scalar effective field theories that appear in the double copy and scattering equations. For a derivatively coupled scalar with a quartic ${\cal O}(p^4)$ vertex, classical conformal invariance dictates an infinite tower of additional interactions that coincide exactly with Dirac-Born-Infeld theory analytically continued to spacetime dimension $D=0$. For the case of a quartic ${\cal O}(p^6)$ vertex, classical conformal invariance constrains the theory to be the special Galileon in $D=-2$ dimensions. We also verify the conformal invariance of these theories by showing that their amplitudes are uniquely fixed by the conformal Ward identities. In these theories, conformal invariance is a much more stringent constraint than scale invariance.

description: The lifetimes of the consecutive $α$ decay chains of recently synthesized new element 115, $^{287}115$ and $^{288}115$, have been calculated theoretically within the WKB approximation using microscopic $α$-nucleus interaction potentials obtained by folding in the densities of the $α$ and the daughter nuclei with a realistic effective interaction. M3Y effective interaction, supplemented by a zero-range pseudo-potential for exchange along with the density dependence, has been used for calculating the nuclear interaction potentials. Spherical charge distributions have been used for calculating the Coulomb interaction potentials. These calculations provide consistent estimates for the lifetimes of the consecutive $α$ decay chains of the superheavy element 115.

description: This article conducts a corpus linguistics analysis on a series of sixteenth- and seventeenth-century manuscripts related to the practice of dance at the Inns of Court in London, in order to examine their possible influence on and relationship with terpsichorean lexis in early modern drama. Still considered one of the fewest – if not the only – extant indigenous proofs of the exercise of dance in early modern England before Playford’s The English Dancing Master (1651), these eight MSS have never been analysed in a single dedicated study. Six of them were transcribed and commented on by some scholars in the second half of the twentieth century, while the seventh was discovered and transcribed in 1992 and the eighth only in 2017. In fact, no thorough discussion of their linguistic peculiarities has been carried out, treating them as a dataset to be investigated through corpus linguistics software. In this article, #Lancsbox software is used to carry out a corpus linguistics analysis primarily focused on the specialized lexis of dance as it emerges from the above-mentioned manuscripts. The eight texts considered have been digitalised as part of the Skenè Digital open-access archives and then uploaded to #Lancsbox to facilitate analysis. Ultimately, this article aims to shed light on the circulation of the terpsichorean lexis in early modern drama. Keywords: Dance; Inns of Court; corpus linguistics; manuscripts; specialized lexis; early modern theatre

description: Several studies published in the last few decades have demonstrated a low priceelasticity for residential water use. In particular, it has been shown that there is a quantity of water demanded that remains constant regardless of prices and other economic factors. In this research, we characterise residential water demand based on a Stone-Geary utility function. This specification is not only theory-compatible but can also explicitly model a minimum level of consumption not dependent on prices or income. This is described as minimum threshold or nondiscretionary water use. Additionally, the Stone-Geary framework is used to model the subsistence level of water consumption that is dependent on the temporal evolution of consumer habits and stock of physical capital. The main aim of this study is to analyse the impact of water-saving habits and water-efficient technologies on residential water demand, while additionally focusing attention on nondiscretionary uses. This is informed by an empirical application using data from a survey conducted among residents of Brisbane City Council, Australia. The results will be especially useful in the design of water tariffs and other water-saving policies.
"But he loves me... to death". An Interview with Director Tonio De Nitto and Translator-Adaptor Francesco Niccolini about their Staging of "La Bisbetica Domata" ("The Taming of the Shrew") for Factory Compagnia Transadriatica

description: The author interviews director Tonio De Nitto and translator-adaptor Francesco Niccolini about their staging of La Bisbetica Domata – an Italian adaptation of Shakespeare’s The Taming of the Shrew produced by Factory Compagnia Transadriatica in 2015 and performed in numerous national and international venues ever since. Tapping into Factory’s deep-rooted attachment to their Apulian residency and De Nitto’s longstanding fascination with Shakespearean drama, the interview delves into the semiotics and semantics of the adaptation, discussing the challenges and the interpretative stances arising from Niccolini’s translation in rhyming couplets and De Nitto’s ‘Burtonian’ staging, marked by thought-provoking casting choices, dismal soundtracks, and meaning-laden scenic, light, and costume designs. Keywords: The Taming of the Shrew; Shakespeare; Tonio De Nitto; Francesco Niccolini; performance.

description: Increasing block tariffs (IBTs) are currently used to price urban water in many Australian mainland capitals and a great many cities worldwide. This paper provides a systematic analysis of the impact of the adoption of IBTs to price urban water under the common constraints of scarce supply and cost recovery. The key tools available to policymakers using IBTs are the volumetric rate in the low tier and the threshold level of that tier. This paper shows how variations in these tools influence (i) the fixed charge set by the firm, (ii) the deadweight loss from the IBT and (iii) the bill paid by customers for particular levels of demand. Our analysis suggests that IBTs are neither fair nor efficient. We propose a modification to IBTs that, while retaining their perception of fairness, results in the efficient allocation of urban water.

description: Natural hazards have a large impact on household livelihoods worldwide, especially in the Global South. Yet, literature on the adoption of risk reduction measures at individual level remains scattered and inconclusive. This study combines geographical data with an original cross-sectional household survey to investigate the effects of both exposure to and experience with landslides on the intention to plant trees to reduce landslide susceptibility. Logit regressions are used to test the protection motivation theory (PMT) and to investigate the link between intentions to plant trees against landslides and past experience, actual exposure, perceived threat and perceived capacity to prevent landslides. The results show that respondents in our study area are well aware of landslide risk and believe trees are effective in landslide susceptibility reduction. Yet, those farmers that would benefit most from reducing landslide susceptibility by planting trees have the lowest intention to do so. A strong, negative correlation is found between exposure and intention to plant trees. A low self-efficacy among these respondents and the presence of a non-protective response trap is proposed to explain this result. This finding has implications for policies for poverty reduction and public communication about landslides.
A Scattering Amplitude in Conformal Field Theory

description: We define form factors and scattering amplitudes in Conformal Field Theory as the coefficient of the singularity of the Fourier transform of time-ordered correlation functions, as $p^2 \to 0$. In particular, we study a form factor $F(s,t,u)$ obtained from a four-point function of identical scalar primary operators. We show that $F$ is crossing symmetric, analytic and it has a partial wave expansion. We illustrate our findings in the 3d Ising model, perturbative fixed points and holographic CFTs.

title: Towards a spatial energy model: A theoretical comparison of accessibility and energy-use in regional settlement patterns
Creators: name: Rickaby, Peter
Publisher: name: The Open University
Year: 1985

description: The research reported is a theoretical investigation of the interaction of land-use and transport in relation to the use of energy. Of particular interest is the relationship between the spatial arrangement of settlements and the use of energy within them for both transport and building services. The literature of scenarios of energy futures is reviewed, and three scenarios of future constraints on regional planning are adopted. The adopted scenarios emphasise constraints imposed by energy policy and the availability of fuels; they form the background to the comparison of a number of theoretical regional settlement patterns, in terms of their implications for land-use and their potential for fuel-conservation. A study of an existing regional settlement pattern is used in combination with published land-use data as the basis of a configurational model. This model is intended to characterise the real pattern spatially, quantitatively and in a manner suitable for experimental manipulation. The model encompasses the pattern of developed land (disaggregated by uses), the shape of the transport network, and the intensity of development (in terms of population and floorspace). A review is then made of published proposals for energy-efficient settlements, which are found to include concentrated, dispersed, nucleated and linear patterns. Five modified versions of the regional configurational model are then constructed in order to characterise the range of realistic possibilities for future regional form which might result from the fuel-conservation policies inherent in the proposals reviewed. The five regional configurations and the original pattern are then compared by means of a specially-developed land-use transport and energy-evaluation model. The comparison is made in terms of the accessibility of the population in each pattern to employment and services (measured 'biy the model as "benefits"), and. in terms of the use of fuel in both transport and domestic space heating. Fuel use in transport is related to modal split and vehicle speed; fuel use in homes is related to dwelling size and location. Parametric calibration of the land-use and transport models allows the comparison of the patterns to be repeated in the context of each of the three adopted energy scenarios, taking into account changes in travelling behaviour, vehicle efficiencies, and building services technologies. The results of the comparison are discussed and assessed in terms of their implications for long-term strategic planning policy.
