Telling and Re-Telling Stories: Staff Witnessing Narratives from People Diagnosed with Dementia
Creators: name: Nagra, Navneet
Publisher: name: University of East London
Year: 2019

description: People navigate an array of emotive and competing narratives which construct the landscape of dementia in the UK. Dominant narratives include biomedical explanations of behaviour and the economic burden of old age. Narratives of person-centred care are equally inflated with emphasis on staff ability and ambivalent definitions of good care. These dynamics risk undermining the heterogeneity of alternative stories from people associated with the label as well as for the people around them. In the current study, the narrative approach of outsider witnessing practice (OWP) was utilised to explore the social location it offered in hearing subjugate narratives of identity from people with a diagnosis of dementia (PDwD) and the narratives of the impact of hearing these from staff. Two PDwD and two staff members were recruited from a dementia day centre, seven stories were produced and analysed. The methodology of narrative analysis was employed to specifically focus on the presence of the wider dominant narratives, experiential stories and interactions in the storytelling constructions of identity. Analysis revealed the significance of social interaction in the constructions of identities for PDwD within OWP, verbal biographical stories weighed significantly in producing shared values and cultural norms, however the interactional elements co-constructed and validated identities of humour, privacy, empathy, determination and many more. Individual staff interviews revealed the pressures faced in providing good support, however OWP offered validation in staff’s more relationship focused approaches in working with PDwD. Implications of the current study include the role of OWP in clinical practice as a space to elicit counter narratives in dementia and health settings as well as raising awareness of professional’s contributions to identity constructions of the people who use services. Moving pressures off of individual staff to provide person centred care and hear staff’s personal and relational narratives of care which can help expand understanding of how best to support each person most meaningfully. Finally, targeting the wider political and societal assumptions by bringing spaces for alternative narratives to be heard more readily in the public realm can diversify the narratives of dementia.

description: Choice experiments (CE) have become widespread as an approach to environmental valuation in both Australia and overseas. However, there are few valuation studies that have addressed natural resource management (NRM) changes in Tasmania. Furthermore, few studies have focussed on the estimation of estuary values. The CE study described in this paper aims to analyse community preferences for NRM options in the George catchment, Tasmania. Catchment health attributes were: the length of native riverside vegetation; the number of rare native animal and plant species in the George catchment; and area of healthy seagrass beds in the Georges Bay, which was used as a measure of estuary condition. Mixed logit models with interactions between socio-economic variables and the choice attributes were estimated to account for systematic and random taste heterogeneity across respondents. Results reveal considerable variation in preferences towards the attributes and show that value estimates are significantly impacted by the way in which we account for preference heterogeneity. Preference heterogeneity thus needs to be considered when estimating community willingness- to-pay for environmental changes. This study further shows little responsiveness to the presented changes in estuary seagrass area.

description: Accurate price forecasting for agricultural commodities can have significant decisionmaking implications for suppliers, especially those of biofuels, where the agriculture and energy sectors intersect. Environmental pressures and high oil prices affect demand for biofuels and have reignited the discussion about effects on food prices. Suppliers in the sugar–alcohol sector need to decide the ideal proportion of ethanol and sugar to optimise their financial strategy. Prices can be affected by exogenous factors, such as exchange rates and interest rates, as well as non-observable variables like the convenience yield, which is related to supply shortages. The literature generally uses two approaches: artificial neural networks (ANNs), which are recognised as being in the forefront of exogenous-variable analysis, and stochastic models such as the Kalman filter, which is able to account for non-observable variables. This article proposes a hybrid model for forecasting the prices of agricultural commodities that is built upon both approaches and is applied to forecast the price of sugar. The Kalman filter considers the structure of the stochastic process that describes the evolution of prices. Neural networks allow variables that can impact asset prices in an indirect, nonlinear way, what cannot be incorporated easily into traditional econometric models.

description: We consider the Sinai model describing a particle diffusing in a 1D random force field. As shown by Golosov, this model exhibits a strong localization phenomenon for the thermal packet: the disorder average of the thermal distribution of the relative distance y=x-m(t), with respect to the (disorder-dependent) most probable position m(t), converges in the limit of infinite time towards a distribution P(y). In this paper, we revisit this question of the localization of the thermal packet. We first generalize the result of Golosov by computing explicitly the joint asymptotic distribution of relative position y=x(t)-m(t) and relative energy u=U(x(t))-U(m(t)) for the thermal packet. Next, we compute in the infinite-time limit the localization parameters Y_k, representing the disorder-averaged probabilities that k particles of the thermal packet are at the same place, and the correlation function C(l) representing the disorder-averaged probability that two particles of the thermal packet are at a distance l from each other. We moreover prove that our results for Y_k and C(l) exactly coincide with the thermodynamic limit of the analog quantities computed for independent particles at equilibrium in a finite sample of length L. Finally, we discuss the properties of the finite-time metastable states that are responsible for the localization phenomenon and compare with the general theory of metastable states in glassy systems, in particular as a test of the Edwards conjecture.

description: In spite of the potential for rice-fish farming in Bangladesh, it has been adopted by relatively few farmers because of socioeconomic, environmental, technological and institutional constraints. Rice monoculture remains the main farming system in Bangladesh even though integrated rice-fish farming is the best farming system in terms of resource utilisation, diversity, productivity, production efficiency and food supply. Only a small number of farmers involve in integrated rice-fish farming. This study concludes that rice-fish farming is as production efficient as rice monoculture and that integrated performs better in terms of cost and technical efficiency compared with alternate rice-fish farming. Integrated rice-fish farming can help Bangladesh keep pace with the current demand for food through rice and fish production. However, a lack of technical knowledge of farmers, high production costs and risks associated with flood and drought are inhibiting more widespread adoption of the practice.

description: We use Molecular Dynamics simulations to study attractive interactions and the underlying ionic correlations between parallel like-charged rods in the absence of additional salt. For a generic bulk system of rods we identify a reduction of short range repulsions as the origin of a negative osmotic coefficient. The counterions show signs of a weak three-dimensional order in the attractive regime only once the rod-imposed charge-inhomogeneities are divided out. We also treat the case of attraction between a single pair of rods for a few selected line charge densities and rod radii. Measurements of the individual contributions to the force between close rods are studied as a function of Bjerrum length. We find that even though the total force is always attractive at sufficiently high Bjerrum length, the electrostatic contribution can ultimately become repulsive. We also measure azimuthal and longitudinal correlation functions to answer the question how condensed ions are distributed with respect to each other and to the neighboring rod. For instance, we show that the prevalent image of mutually interlocked ions is qualitatively correct, even though modifications due to thermal fluctuations are usually strong.

description: The adsorption of metal atoms on nanostructures, such as graphene and nanotubes, plays an important role in catalysis, electronic doping, and tuning material properties. Quantum chemical calculations permit the investigation of this process to discover desirable interactions and obtain mechanistic insights into adsorbate behavior, of which the binding strength is a central quantity. However, binding strengths vary widely in the literature, even when using almost identical computational methods. To address this issue, we investigate the adsorption of a variety of metals onto graphene, carbon nanotubes, and boron nitride nanotubes. As is well-known, calculations on periodic structures require a sufficiently large system size to remove interactions between periodic images. Our results indicate that there are both direct and indirect mechanisms for this interaction, where the latter can require even larger system sizes than typically employed. The magnitude and distance of the effect depend on the electronic state of the substrate and the open- or closed-shell nature of the adsorbate. For instance, insulating substrates (e.g., boron nitride nanotubes) show essentially no dependence on system size, whereas metallic or semi-metallic systems can have a substantial effect due to the delocalized nature of the electronic states interacting with the adsorbate. We derive a scaling relation for the length dependence with a representative tight-binding model. These results demonstrate how to extrapolate the binding energies to the isolated-impurity limit.

Radio/X-ray Offsets of Large Scale Jets Caused by Synchrotron Time Lags

description: In the internal shock scenario, we argue that electrons in most kpc (or even larger) scale jets can be accelerated to energies high enough to emit synchrotron X-rays, if shocks exist on these scales. These high energy electrons emit synchrotron radiation at high frequencies and cool as they propagate downstream along the jet, emitting at progressively lower frequencies and resulting in time lags and hence radio/X-ray (and optical/X-ray if the optical knot is detectable) offsets at bright knots, with the centroids of X-ray knots being closer to the core. Taking into account strong effects of jet expansion, the behaviour of radio/X-ray and optical/X-ray offsets at bright knots in M87, Cen A, 3C 66B, 3C 31, 3C 273, and PKS 1127-145 is consistent with that of synchrotron time lags due to radiative losses. This suggests that the large scale X-ray and optical jets in these sources are due to synchrotron emission.

Barriers Encountered by Young People From Black and Minority Ethnic Communities Accessing Psychological Services: Clinical Psychologists’ Perspectives
Creators: name: Mckellar, Jack
Publisher: name: University of East London
Year: 2019

description: This research explores clinical psychologist’s perspectives on barriers to accessing psychological services for young people from Black, Minority and Ethnic (BME) communities. This study follows an analysis of the current and historical contexts of clinical psychology and its relationship with ‘race’ thinking. Particular attention is paid to the theory and practice of clinical psychology and its application across different ethnic contexts, as well as the legislative backdrop as it relates to children and young people. These aspects are considered to be implicated in disparities in access to psychology services for BME young people and families. Eight clinical psychologists were interviewed, and the resulting transcripts analysed using thematic analysis from a critical realist epistemology. Three main themes were identified. Theme One concerns the profession’s predominant Whiteness and how this interacts with the task of improving access for BME young people and families. Theme Two considers the individual and systemic enablers and disablers to greater equality and how these are navigated by participants. Theme Three considers clinical psychologist’s perspectives on ethnic inequities in respect to how systems of language and service structure might create and ameliorate barriers to access. Implications for clinical psychology practice and further research are considered. The findings indicate more should be done on individual and structural levels to facilitate clinical psychologists improving access for BME young people and families.

description: We examine the stability of magnetic order in a classical Heisenberg model with quenched random exchange couplings. This system represents the spin degrees of freedom in high-$T_\textrm{c}$ compounds with immobile dopants. Starting from a replica representation of the nonlinear $σ$-model, we perform a renormalization-group analysis. The importance of cumulants of the disorder distribution to arbitrarily high orders necessitates a functional renormalization scheme. From the renormalization flow equations we determine the magnetic correlation length numerically as a function of the impurity concentration and of temperature. From our analysis follows that two-dimensional layers can be magnetically ordered for arbitrarily strong but sufficiently diluted defects. We further consider the dimensional crossover in a stack of weakly coupled layers. The resulting phase diagram is compared with experimental data for La$_{2-x}$Sr$_x$CuO$_4$.

Life on the Borderline: Reconceptualising the Experiences of People With a Diagnosis of Borderline Personality Disorder
Creators: name: Bogart, Katherine
Publisher: name: University of East London
Year: 2019

description: The label of BPD was introduced as a formal psychiatric diagnosis in 1952. The reliability and validity of the diagnosis has been a source of contention in the professional field since this time. The diagnostic criteria have been frequently revised with a view to improve the reliability and validity of the construct. This research aimed to explore the stories of people with a diagnosis of BPD and to assess whether there were commonly shared experiences between them. Semi-structured interviews were conducted with eight people who had been given a diagnosis of BPD. Participants were recruited from a range of internet sources, twitter, forums and support networks. A Grounded Theory analysis of the data was conducted, and three categories were generated; Intense Experiences of Emotion, The Importance of Understanding, and the Fear of Repeated Relational Patterns. A conceptual model was not generated from the data. This was concluded to be reflective of the issues of validity and heterogeneity in the clinical population. The findings are discussed in relation to existing literature. Clinical implications are made which include paying attention to the individual stories told by people with a diagnosis of BPD, understanding the complex and unique function of self-harm and responding to aetiology rather than symptoms. Finally, recommendations for future research are highlighted.

description: The paper jointly evaluates the determinants of switching to modern rice and its productivity while allowing for production inefficiency at the level of individual producers. Model diagnostics reveal that serious selection bias exists, justifying the use of a sample selection framework in stochastic frontier models. Results revealed that modern variety selection decisions are influenced positively by the availability of irrigation and gross return from rice and negatively by a rise in the relative wage of labour. Adoption of modern rice is higher in underdeveloped regions. Seasonality and geography/ location does matter in adoption decisions. Stochastic production frontier results reveal that land, labour and irrigation are the significant determinants of modern rice productivity. Decreasing returns to scale prevail in modern rice production. The mean level of technical efficiency (MTE) is estimated at 0.82. Results also demonstrate that the conventional stochastic frontier model significantly overestimates inefficiency by three points (MTE = 0.79). Policy implications include measures to increase access to irrigation, tenurial reform and keeping rice prices high to boost farm returns and offset the impact of a rise in the labour wage which will synergistically increase the adoption of modern rice as well as farm productivity.

description: We generate data-driven reduced order models (ROMs) for inversion of the one and two dimensional Schrödinger equation in the spectral domain given boundary data at a few frequencies. The ROM is the Galerkin projection of the Schrödinger operator onto the space spanned by solutions at these sample frequencies. The ROM matrix is in general full, and not good for extracting the potential. However, using an orthogonal change of basis via Lanczos iteration, we can transform the ROM to a block triadiagonal form from which it is easier to extract $q$. In one dimension, the tridiagonal matrix corresponds to a three-point staggered finite-difference system for the Schrödinger operator discretized on a so-called spectrally matched grid which is almost independent of the medium. In higher dimensions, the orthogonalized basis functions play the role of the grid steps. The orthogonalized basis functions are localized and also depend only very weakly on the medium, and thus by embedding into the continuous problem, the reduced order model yields highly accurate internal solutions. That is to say, we can obtain, just from boundary data, very good approximations of the solution of the Schrödinger equation in the whole domain for a spectral interval that includes the sample frequencies. We present inversion experiments based on the internal solutions in one and two dimensions.

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

description: We describe a directed avalanche model; a slowly unloading sandbox driven by lowering a retaining wall. The directness of the dynamics allows us to interpret the stable sand surfaces as world sheets of fluctuating interfaces in one lower dimension. In our specific case, the interface growth dynamics belongs to the Kardar-Parisi-Zhang (KPZ) universality class. We formulate relations between the critical exponents of the various avalanche distributions and those of the roughness of the growing interface. The nonlinear nature of the underlying KPZ dynamics provides a nontrivial test of such generic exponent relations. The numerical values of the avalanche exponents are close to the conventional KPZ values, but differ sufficiently to warrant a detailed study of whether avalanche correlated Monte Carlo sampling changes the scaling exponents of KPZ interfaces. We demonstrate that the exponents remain unchanged, but that the traces left on the surface by previous avalanches give rise to unusually strong finite-size corrections to scaling. This type of slow convergence seems intrinsic to avalanche dynamics.

The Experiences of Restorative Justice Practices for Those Attending an Alternative Provision: A Thematic Analysis
Creators: name: Bentley, Sophia
Publisher: name: University of East London
Year: 2019

description: Restorative practices can be traced back to the Maori communities in New Zealand and have their historical and cultural origins in those communities. Restorative practices were then applied in the criminal justice sector throughout the 1980s and 1990s, and a decade later in the education sector. The argued benefit of restorative practice in schools is that it can help to shift the focus from ‘zero-tolerance’ approaches to less punitive approaches, providing young people with the opportunity to learn and develop skills when conflict occurs. Current research in the UK tends to focus on the evaluation of restorative practices, with a focus on its effect on reducing exclusions and other sanctions. There is good evidence that restorative practices are successful in reducing exclusions and that it is a good alternative to the ‘zero-tolerance’ behaviour policies in mainstream schools. However, there is a distinct lack of research being carried out in specialist settings such as pupil referral units and alternative provisions. Additionally, much of the qualitative research has focussed more on the adult’s perceptions and does not give a lot of detail on young people’s experiences of restorative practices. I conducted my research in an alternative provision with six young people who had experienced at least one restorative meeting. I gathered the young people’s views through semi-structured interviews and analysed the transcripts using thematic analysis. Three major themes were identified, with several subthemes. Theme one highlighted that the young people had knowledge of restorative meetings, but that their understanding of the purpose of these meetings deviated from the underpinnings of restorative practices. Similarly, theme two showed that the young people were broadly critical of the process and spoke about areas such as equality, feelings of disempowerment and the application of restorative practice. Theme three demonstrated they had both positive and negative reflections on their previous education setting. These themes raise questions on how restorative practice is being used in this setting and how the young people have interpreted and responded to its use. The findings suggest that, at least in this setting, young people’s experience of restorative practice is not always being applied in a way that aligns with its underlying principles. The potential implications of this misalignment are discussed and suggestions for evidence-based practice are outlined.

description: We present a detailed analysis of the distance determination for one intermediate Velocity Cloud (IVC G139.6+47.6) from the ongoing DDO IVC Distance Project. Stars along the line of sight to G139.6+47.6 are examined for the presence of sodium absorption attributable to the cloud, and the distance bracket is established by astrometric and spectroscopic parallax measurements of demonstrated foreground and background stars. We detail our strategy regarding target selection, observational setup, and analysis of the data, including a discussion of wavelength calibration and sky subtraction uncertainties. We find a distance estimate of 129 (+/- 10) pc for the lower limit and 257 (+211-33) pc for the upper limit. Given the high number of stars showing absorption due to this IVC, we also discuss the small-scale covering factor of the cloud and the likely significance of non-detections for subsequent observations of this and other similar IVC's. Distance measurements of the remaining targets in the DDO IVC project will be detailed in a companion paper.

description: With a central surface brightness of $μ_0=29.3$ mag. per sq. arcsec, and half-light radius of $r_{\rm half}=3.1^{+0.9}_{-1.1}$~kpc, Andromeda XIX (And XIX) is an extremely diffuse satellite of Andromeda. We present spectra for $\sim100$ red giant branch stars in this galaxy, plus 16 stars in a nearby stellar stream. With this exquisite dataset, we re-derive the properties of And XIX, measuring a systemic velocity of $v_r=-109.0\pm1.6$ km/s and a velocity dispersion of $σ_v = 7.8^{+1.7}_{-1.5}$ km/s (higher than derived in our previous work). We marginally detect a velocity gradient along the major axis of ${\rm d}v/{\rm d}r = -2.1\pm1.8$ km/s kpc$^{-1}$. We find its mass-to-light ratio is higher than galaxies of comparable stellar mass ($[M/L]_{\rm half} = 278^{+146}_{-198}M_\odot/L_\odot$), but its dynamics place it in a halo with a similar total mass to these galaxies. This could suggest that And XIX is a "puffed up" dwarf galaxy, whose properties have been altered by tidal processes, similar to its Milky Way counterpart, Antlia II. For the nearby stream, we measure $v_r=-279.2\pm3.7$ km/s, and $σ_v=13.8^{+3.5}_{-2.6}$ km/s. We measure its metallicity, and find it to be more metal rich than And XIX, implying that the two features are unrelated. Finally, And XIX's dynamical and structural properties imply it is a local analogue to ultra diffuse galaxies (UDGs). Its complex dynamics suggest that the masses of distant UDGs measured from velocity dispersions alone should be carefully interpreted

An Exploration of the Use of Solution Circles as an Intervention with Secondary School Pupils
Creators: name: Elliott, Rebecca
Publisher: name: University of East London

description: Solution Circles is a structured tool for problem solving that has mostly been used with adults as part of peer supervision for school staff, or in educational psychology practice, but there is a scarcity of published research exploring or investigating its use. In particular, there is no available published literature exploring the use of Solution Circles as a weekly intervention with young people. Given that there is a significant focus on schools supporting children and young people’s social, emotional and mental health needs, the research aimed to explore the use of weekly Solution Circle intervention groups across two secondary schools. The mixed methods research, conducted from a pragmatic perspective, involved a total of 36 participants, which included thirty pupil participants – six of whom contributed to a pilot study, two Special Educational Needs Coordinators, and four Solution Circle group Facilitators. Quantitative data indicated that all pupil participants had made progress toward their personalised targets, and 55 per cent of them had either reached or exceeded their expected targets. Inferential statistics conducted on scores of a self-report resilience measure indicated that pupil participants’ scores on the Sense of Mastery subscale significantly increased, but scores on the Relatedness subscale, Emotional Reactivity subscale, Resource index and Vulnerability index did not differ significantly. This indicates an increase in pupil participants’ optimism, self-efficacy and adaptability. Thematic analysis of qualitative data gathered from focus groups with pupil participants and interviews with Facilitators and Special Educational Needs Coordinators highlighted three overarching themes relating to pupils’ experiences of the group, and adults’ views on the feasibility of setting up and running the groups. The themes were processes, outcomes and the future. Processes related to practicalities and structures; outcomes related to efficacy, internal resources and external resources; and the future highlighted considerations and ideas for any changes that schools might want to consider for future use of the intervention, and motivation for the school staff and young people to continue using the intervention. The promising findings from this research highlight how future use of Solution Circles groups in schools could be beneficial in increasing confidence, resilience, and providing young people with widened external support systems.

Peierls-like transition induced by frustration in a two-dimensional antiferromagnet
Creators: name: Becca, Federico

Publisher: name: arXiv
Year: 2002
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We show that the introduction of frustration into the spin-1/2 two-dimensional (2D) antiferromagnetic Heisenberg model on a square lattice via a next-nearest neighbor exchange interaction can lead to a Peierls-like transition, from a tetragonal to an orthorhombic phase, when the spins are coupled to adiabatic phonons. The two different orthorhombic ground states define an Ising order parameter, which is expected to lead to a finite temperature transition. Implications for ${\rm Li_2VOSiO_4}$, the first realization of that model, will be discussed.

description: In search of more potent new antitubercular agents, a library of novel piperazine tethered dimeric 1,2,3-triazoles were designed by assembling 1,2,3-triazoles and piperazine in a single molecular architectural framework. The titled compounds (3a–m) were synthesized by 1,3-dipolar cycloaddition of 1,4-di(prop-2-yn-1-yl)piperazine (1) and various azides (2a–m) using click chemistry approach with good yields. All the synthesized compounds (3a–m) have been screened for their in vitro antitubercular, antifungal and antioxidant activities against their respective strains. Among them, 3b, 3d, and 3i have revealed promising antitubercular activity against Mycobacterium tuberculosis (Mtb) H37Rv with MIC 12.5 µg/mL. Molecular docking results provided well-clustered solutions to the mode of binding for these molecules into the active site of Mtb enoyl reductase (InhA). In addition to this, most of synthesized compounds were found to have potential antifungal as well as antioxidant activity.

description: We present the Chandra results of AX J1843.8-0352, a supernova remnant (SNR) recently identified with ASCA. Chandra spatially resolved two components from this SNR: non-thermal and thermal ones. The morphology of the non-thermal component is clumpy and elliptical, elongated from the north to the south with a mean diameter of about 9 arcmin. The spectrum is fitted with a power-law model of photon index 2.1 and the east rim is associated with the non-thermal radio sources C and F (Helfand et al. 1989). Therefore the non-thermal component is probably synchrotron X-rays by energetic electrons accelerated at the shell of the SNR. The thermal component is the brightest clump located within the non-thermal component and shows a spectrum of a thin plasma of about 0.7 keV temperature. Notable discovery is its peculiar morphology; a head of 50 arcsec x 30 arcsec size near the south-east rim of the SNR and a 30 arcsec-long ``jet'' pointing to the southwest. Although this emission is associated with the west part of the radio source F, the absorption is twice larger than that of the non-thermal X-rays, or the bulk of the SNR emission. Therefore, it is unclear whether this peculiar plasma is a thermal component associated with AX J1843.8-0352, a Galactic source located in the far side of our Galaxy, or an extragalactic source.
