description: We study the resonant x-ray scattering (RXS) spectra at the Dy $L_{\rm III}$ absorption edge in the quadrupole ordering phase of DyB$_2$C$_2$. Analyzing the buckling of sheets of B and C atoms, we construct an effective model that the crystal field is acting on the $5d$ and $4f$ states with the principal axes different for different sublattices. Treating the $5d$ states as a band and the $4f$ states as localized states, we calculate the spectra within the dipole transition. We take account of processes that (1) the lattice distortion directly modulates the $5d$ states and (2) the charge anisotropy of the quadrupole ordering $4f$ states modulates the $5d$ states through the $5d$-$4f$ Coulomb interaction. Both processes give rise to the RXS intensities on $(00\frac{\ell}{2})$ and $(h0\frac{\ell}{2})$ spots. Both give similar photon-energy dependences and the same azimuthal-angle dependences for the main peak, in agreement with the experiment. The first process is found to give the intensities much larger than the second one in a wide parameter range of crystal field. This suggests that the main-peak of the RXS spectra is not a direct reflection of the quadrupole order but mainly controlled by the lattice distortion.

description: The linear and nonlinear properties of the Rao-dust-magnetohydrodynamic (R-D-MHD) waves in a dusty magnetoplasma are studied. By employing the inertialess electron equation of motion, inertial ion equation of motion, Ampère's law, Faraday's law, and the continuity equation in a plasma with immobile charged dust grains, the linear and nonlinear propagation of two-dimensional R-D-MHD waves are investigated. In the linear regime, the existence of immobile dust grains produces the Rao cutoff frequency, which is proportional to the dust charge density and the ion gyrofrequency. On the other hand, the dynamics of an amplitude modulated R-D-MHD waves is governed by the cubic nonlinear Schroedinger equation. The latter has been derived by using the reductive perturbation technique and the two-timescale analysis which accounts for the harmonic generation nonlinearity in plasmas. The stability of the modulated wave envelope against non-resonant perturbations is studied. Finally, the possibility of localized envelope excitations is discussed.

title: Roles of Replication-associated Factors in Cohesin Regulation
Creators: name: Kawasumi, Ryotaro
Publisher: name: The Open University
Year: 2022

description: Cohesin is a ring-shaped protein complex that consists of four core subunits: SMC1 and SMC3 forming a V-shape heterodimer held together at the open ends by the cohesin’s kleisin component, RAD21, and either SA1 or SA2 that associate with RAD21. Functionally, the cohesin ring mediates DNA-DNA interactions between distant loci both in cis and in trans, the latter type being important for sister chromatid cohesion, SCC. The SCC function of cohesin involves topological entrapment of one or two DNA strands into its lumen. Functionally, SCC is important for accurate segregation of chromosomes in mitosis and facilitates error-free recombination repair, overall being critical for genome integrity. Cohesin-DNA interaction is facilitated by the cohesin loader NIPBL-MAU2 and downregulated by WAPL-PDS5 that facilitates unloading of cohesin. The stabilization of cohesin on DNA against WAPL-mediated unloading is favored by cohesin acetylation at two evolutionarily conserved sites on SMC3 that is mediated by Eco1/Eso1 in budding and fission yeast, and by ESCO1 and ESCO2 in vertebrates. In addition, several replisome-associated components are involved in SCC establishment. However, their functions remain incompletely understood, especially in vertebrate cells that contain additional cohesin regulators. Using chicken lymphoma DT40 cells suitable for genetic engineering and cytogenetic studies, I aimed to understand the roles of ESCO1/2 and replication-associated factors in cohesin regulation. Our study revealed previously unknown roles for ESCO1/2 in interphase chromatin organization and both functional separation and cooperation in SCC and proliferation. Moreover, we found that dysfunctions in replisome-associated components can lead to SCC cohesion defects that depend on WAPL but less so on ESCO1/2-mediated SMC3 acetylation. Finally, our IP-MS experiments identified novel cohesin interactors, RUVBL1 and RUVBL2, with roles in SCC. Thus, additional regulations are likely to exist in vertebrate cells to instruct cohesin abundance and its cohesive state.

description: Any supersymmetric mechanism to solve the flavour puzzle would generate mixing both in the superpotential Yukawa couplings and in the Kahler potential. In this paper we study, in a model independent way, the impact of the nontrivial structure of the Kahler potential on the physical mixing matrix, after kinetic terms are canonically normalized. We undertake this analysis both for the quark sector and the neutrino sector. For the quark sector, and in view of the experimental values for the masses and mixing angles, we find that the effects of canonical normalization are subdominant. On the other hand, for the leptonic sector we obtain different conclusions depending on the spectrum of neutrinos. In the hierarchical case we obtain similar conclusion as in the quark sector, whereas in the degenerate and inversely hierarchical case, important changes in the mixing angles could be expected.

title: Detecting Discrete Scale Invariance In Financial Markets
Creators: name: Lynch, Christopher
Publisher: name: The Open University
Year: 2020

description: This thesis presents methodologies to identify periods in financial markets where the governing regime shows characteristics of discrete scale invariance. Log-periodic power laws often occur as signatures of impending criticality of hierarchical systems in the physical sciences, and it has been proposed that similar signatures may be apparent in the price evolution of financial markets as bubbles form. The features of such market bubbles have been extensively studied over the past twenty–five years, and models derived from an initial discrete scale invariance assumption have been developed and tested against the wealth of financial data with varying degrees of success. In this thesis, the equations that form the basis for the standard log-periodic power law model and its higher extensions are compared to a logistic model derived from the solution of the Schröder equation for the renormalisation group with nonlinear scaling function. Subsequently, a methodology is developed to identify change–points in financial markets where the governing regime shifts from a constant rate-of-return, i.e. from normal growth, to superexponential growth described by a power-law hazard rate. It is suggested that superexponential regimes correspond to financial bubbles and anti-bubbles driven by herding behaviour of market participants. It is from this theory that a predictive algorithm is developed that may have merit in identifying not only when a period of herding behaviour begins, and where it ends. The theory also provides tools which may facilitate profitable trading strategies across a broad spectrum of asset classes.

title: Systems Biology Approaches To Unravel The Mechanisms Underlying The Evolution Of The Transcription Factor Brachyury
Creators: name: Ranđelović, Jovana
Publisher: name: The Open University
Year: 2020

description: Bilaterians share a conserved molecular toolkit depicted in Gene Regulatory Networks (GRNs) that controls embryonic development and morphogenesis. Modifications of this toolkit can lead to the evolution of new cell types and new body plans. This work investigates the role of transcription factor (TF) Brachyury in the embryonic development of two sea urchin species – Strongylocentrotus purpuratus and Paracentrotus lividus.

 In non-vertebrate and vertebrate chordates, Brachyury acts as an activator of mesodermal genes. However, in protostomes, Brachyury activates endodermal and ectodermal genes, suggesting its ancestral function. Sea urchin, due to its phylogenetic position as a non-vertebrate deuterostome, the thorough characterization of its GRNs, and the expression of Brachyury in ectodermal and endodermal domains, served as a model system for this study. The goal of this study is to identify direct and indirect Brachyury targets and untangle the similarities and differences in Brachyury's role and function in the early development of two sea urchin species by combining gene perturbation and high-throughput sequencing technologies. The knock-down of Brachyury, followed by differential transcriptomics, allowed the investigation of its putative targets. Moreover, the use of available Brachyury ChIP-seq data to identify Brachyury direct interactions and ATAC-seq to discover open chromatin regions has led to the extension of a known GRN around Brachyury in S. purpuratus.

 This work showed that Brachyury acts mostly as an ectodermal and endodermal activator in both sea urchin species. Some mesodermal genes detected after the perturbation were commonly affected in both species, although it appears that Brachyury can directly repress mesodermal fate in endodermal veg2 cell lineage in S. purpuratus. The self-regulatory feedback loop of Brachyury seems to be conserved. Moreover, the analysis of the obtained data suggested the direction for further work.

It is shown that these models may be naturally considered as interacting (holomorphic and anti-holomorphic) $βγ$-systems. Besides, using the theory of nilpotent orbits of complex Lie groups, we establish a relation to the principal chiral model.

The lattice distortion due to Pr-substitution and anisotropic thermal conductivity in bilayer manganites are discussed on the basis of different relaxation models of local lattice distortions in metal and insulating states proposed by Maderda et al. The giant magnetothermal effect is scaled as a function of magnetization and discussed on the basis of a systematic variation of the occupation of the $e_g$-electron orbital states due to Pr-substitution.

title: IL-1R8 Acts As An Immune Checkpoint In CD8+ T Cells
Creators: name: Supino, Domenico
Publisher: name: The Open University
Year: 2022

description: IL-1R8 is a member of the Interleukin-1 receptor (ILR) family, acting as a negative regulatory receptor that inhibits inflammation by dampening ILR and Toll-like receptor (TLR) signaling pathways. IL-1R8 deficiency was shown to enhance IL-18-promoted NK cell effector functions restraining tumor metastasis and viral dissemination. IL-1R8 is thus considered a new immunocheckpoint of innate lymphoid cells.

 CD8+ T cells represent a potent and target-specific component of anti-tumor immunity, which can be targeted to overcome tumor-associated immune dysfunction in the context of cancer immunotherapy. The aim of this project was to dissect the role played by IL-1R8 in Cytotoxic T lymphocytes (CTLs). Expression profile analysis indicated that IL-1R8 was transcriptionally and epigenetically controlled along immune cell differentiation. In particular, IL-1R8 was upregulated as a consequence of T cell maturation in physiologic and pathologic contexts and its expression was associated with the acquisition of early-effector markers in healthy donors and tumor patients. We demonstrated that IL-1R8 genetic deficiency promoted CD8+ T cell-mediated protection in immunogenic tumor models and enhanced effector functions in IL-1R8-silenced human CD8+ T cells. Surprisingly, we found that IL-1R8 regulated T cells through the integration of two independent cell-autonomous mechanisms. IL-1R8 deficiency promoted Type-1 responses and enhanced IL-18-mediated pathway by inducing TBET. In addition, IL-1R8 regulated the IL-2/EOMES/CD25 signaling axis consequently affecting T cell maturation, proliferation and cytokines production in TBET+ EOMES+ CD8+ T cells.

 The analysis of IL-1R8 transcription showed a complex mechanism of regulation, including epigenetic modifications, two transcription-starting sites and transcription of truncated isoforms.

 Collectively, our data showed that IL-1R8 acts as a checkpoint for mouse and human CD8+ T cells and its expression is upregulated during the transition from naïve to mature CD8+ T cells, hence suggesting that IL-1R8 genetic targeting represents a tool to enhance the activity of CD8+ T cells, including CAR-T cells, in cancer immunotherapy.

title: Analysis of Defects in Transcriptional Regulation Mechanisms in High-Grade Serous Ovarian Cancer and Their Correlation with Clinic-Pathological Features
Creators: name: Paracchini, Lara
Publisher: name: The Open University
Year: 2020

description: High grade serous epithelial ovarian cancer (HGS-EOC) is the most lethal gynaecological disease, usually diagnosed at advanced stages. Although most HGS-EOC patients are initially sensitive to therapy, about 20% of them does not respond to front-line platinum (Pt)-based chemotherapy, relapsing within 6 months from treatment. No molecular biomarkers are as yet available in the clinical practice to discriminate, at the time of diagnosis, the patients who will respond or not to first-line Pt treatment. The identification of a molecular signature associated with intrinsic Pt resistance would allow to select patients who will not respond to Pt compound, thus avoiding ineffective treatment and related toxicities. In this thesis, defects in transcriptional regulation mechanisms associated to intrinsic Pt resistance were investigated using two different omic approaches – microarray and RNA sequencing. Moreover, considering the correlation between defects in DNA repair Homologous Recombination and Pt sensitivity, we have started to develop an academic assay which exploits high-throughput DNA sequencing to evaluate Homologous Recombination Deficiency (HRD). Results obtained from three independent HGS-EOC cohorts (n=1080) indicate that the combined expression profile of three genes – PRKG1, SDF2L1 and PPP1R12A – could represent an independent prognostic biomarker for Pt response and survival. In addition, 25 transcripts, 16 of which are unknown or partially known variants, have been identified that are differentially expressed between Pt-sensitive and Pt-resistant patients. These results, once validated, integrated and associated with the HRD status, could identify a molecular signature applicable in the clinical setting to enable stratification of patients at time of diagnosis, allowing to choose the best therapeutic option.

description: The celebrated Dyson singularity signals the relative delocalization of single-particle wave functions at the zero-energy symmetry point of disordered systems with a chiral symmetry. Here we show that analogous zero modes in interacting quantum systems can fully localize at sufficiently large disorder, but do so less strongly than nonzero modes, as signifed by their real-space and Fock-space localization characteristics. We demonstrate this effect in a spin-1 Ising chain, which naturally provides a chiral symmetry in an odd-dimensional Hilbert space, thereby guaranteeing the existence of a many-body zero mode at all disorder strengths. In the localized phase, the bipartite entanglement entropy of the zero mode follows an area law, but is enhanced by a system-size-independent factor of order unity when compared to the nonzero modes. Analytically, this feature can be attributed to a specific zero-mode hybridization pattern on neighboring spins. The zero mode also displays a symmetry-induced even-odd and spin-orientation fragmentation of excitations, characterized by real-space spin correlation functions, which generalizes the sublattice polarization of topological zero modes in noninteracting systems, and holds at any disorder strength.

description: We present a simple exact analytical solution, using the Weyl-Titchmarsh-Kodaira spectral theorem, for the spectral function of the one-dimensional diatomic molecule model consisting of two attractive delta function wells in the presence of a static external electric field. For sufficiently deep and far apart wells, this molecule supports both an even and an odd state, and the introduction of a static electric field turns these bound states into quasi-bound states which are Stark shifted and broadened. The continuum spectrum also inherits an intricate pattern of resonances which reflect the competition between resonant scattering between the two atomic wells and between the linear potential and one or both atomic well(s). All results are analytic and can be easily plotted. The relation between the large orders of the divergent perturbative Stark shift series and the non-perturbative widths of quasi-bound levels is studied.

description: Given a set $Σ$ of equations, the free-algebra functor $F_Σ$ associates to each set $X$ of variables the free algebra $F_Σ(X)$ over $X$. Extending the notion of \emph{derivative} $Σ'$ for an arbitrary set $Σ$ of equations, originally defined by Dent, Kearnes, and Szendrei, we show that $F_Σ$ preserves preimages if and only if $Σ\vdash Σ'$, i.e. $Σ$ derives its derivative $Σ'$. If $F_Σ$ weakly preserves kernel pairs, then every equation $p(x,x,y)=q(x,y,y)$ gives rise to a term $s(x,y,z,u)$ such that $p(x,y,z)=s(x,y,z,z)$ and $q(x,y,z)=s(x,x,y,z)$. In this case n-permutable varieties must already be permutable, i.e. Mal'cev. Conversely, if $Σ$ defines a Mal'cev variety, then $F_Σ$ weakly preserves kernel pairs. As a tool, we prove that arbitrary $Set-$endofunctors $F$ weakly preserve kernel pairs if and only if they weakly preserve pullbacks of epis.
title: Lost in Transition: Hugh Walpole 1909-1941
Creators: name: Hartley, John Cameron
Publisher: name: The Open University
Year: 2020

description: Hugh Walpole was born in 1884, and arrived on the literary scene at the first attempt with his novel The Wooden Horse (1909), just as literary modernism was making its mark. Loyal to the traditional novel of plot and character, he was nevertheless aware that writers of his own generation were breaking new literary ground, and he would express the ambition to create a novel of transition marrying tradition and modern experiment. His commercial success, unabashed occupation of the middlebrow middle-ground, adherence to a tradition of romance writing, and love of the macabre, would put him at odds with highbrow modernism, even as he moved in the same circles and published in the same journals.

 Eager to be seen as a serious novelist, and recognising the turbulent times he was living through, Walpole embarked upon a sequence of novels charting the first three decades of the twentieth-century, concentrating upon life in the city, in the provinces, and in the countryside. As he wrote, the world was plunged into war, revolution, and economic crisis. Alongside his social novels he produced genre macabres and historical fiction while writing literary criticism in his belles lettres, and charting the culture wars between middlebrow and highbrow.

 With reference to a variety of creative writers and critics of his own day, including Ford Madox Ford, Joseph Conrad, and John Middleton Murry, and current critics of Gothic Modernism, this study considers two contexts as background to Walpole’s literary career: literary modernism which dominates any study of the period, and the romantic tradition which underpins his own writing. Then, through close reading of the texts, the study examines if Walpole succeeded in documenting his times by creating his literature of transition, and his value as a witness to turbulent times.

description: Background: A recent coupled reaction channel (CRC) study shows that the enhanced oscillation of the elastic $^{16}$O+$^{12}$C cross section at backward angles is due mainly to the elastic $α$ transfer or the core exchange. Such a process gives rise to a parity-dependent term in the total elastic $S$-matrix, an indication of the parity dependence of the $^{16}$O+$^{12}$C optical potential (OP). Purpose: To explicitly determine the core exchange potential (CEP) induced by the symmetric exchange of the two $^{12}$C cores in the elastic $^{16}$O+$^{12}$C scattering at $E_{\rm lab}= 132$ and 300 MeV, and explore its parity dependence. Method: $S$-matrix generated by CRC description of the elastic $^{16}$O+$^{12}$C scattering is used as the input for the inversion calculation to obtain the effective local OP that contains both the Wigner and Majorana terms. Results: The high-precision inversion results show a strong contribution by the complex Majorana term in the total OP of the $^{16}$O+$^{12}$C system, and thus provide for the first time a direct estimation of the parity-dependent CEP. Conclusions: The elastic $α$ transfer or exchange of the two $^{12}$C cores in the $^{16}$O+$^{12}$C system gives rise to a complex parity dependence of the total OP. This should be a general feature of the OP for the light heavy-ion systems that contain two identical cores.

title: Under Pressure to Be ‘Normal’: An Exploration of the Material-Discursive Practices that Affect the Experience of Disability and Gender in Employment.
Creators: name: Bend, Gemma
Publisher: name: The Open University
Year: 2020

description: Research has demonstrated that disabled women and men encounter barriers within employment. Often, these experiences are exacerbated when organisational practices fail to consider the embodied experiences of disabled women and men. This perpetuates experiences of inequality and exclusion within working spaces. This thesis draws on the theory of feminist posthumanist performativity to explore if and how the practices enacted within organisations oppress and exclude disabled women and men. This thesis is based on two studies from two types of employment in the United Kingdom: sheltered and mainstream employment. Study one employs ethnographic participant observations and semi-structured interviews within a manufacturing sheltered workshop. Study two utilises semi-structured interviews to elicit a wider view of disabled people’s experiences in different types of mainstream employment. The data analysis is organised around five themes: (a) inclusion, exclusion and discrimination; (b) cognitive and physical barriers to workplace participation; (c) practical and work-based support; (d) performative enactment of difference; and (e) resisting and disrupting oppressive practices. The findings demonstrate how materiality intra-acts with social discourses to affect the performative enactment of identities in the workplace. Furthermore, the analysis reveals how policies and practices enacted within organisations exclude or include employees through reproducing or challenging normative and essentialist conceptualisations of disability and gender. The thesis’ contribution to posthumanist performativity is threefold: Firstly the analysis critically explores how material-discursive practices enacted within contemporary systems of work constrain access to, and progression within, employment for disabled women and men. Secondly, the study adds evidence to the limited studies that explore how identities such as disability and gender are performatively enacted as forms of oppression. Thirdly, the thesis gives evidence of how the performative enactment of minority identities as forms of oppression are disrupted and challenged through strategies that emerge within a feminist posthumanist performative lens, specifically transformative affirmative ethics.

description: It is important to enhance penetration depth of nanomedicine and realise rapid drug release simultaneously at targeted tumour for improving anti-tumour efficiency of chemotherapeutic drugs. This project employed sodium alginate (Alg) as matrix material, to establish tumour-responsive nanogels with particle size conversion and drug controlled release functions. Specifically, tumour-targeting peptide CRGDK was conjugated with Alg first (CRGDK-Alg). Then, doxorubicin (DOX) was efficiently encapsulated in CRGDK-FeAlg nanogel during the cross-linking process (CRGDK-FeAlg/DOX). This system was closed during circulation. Once reaching tumour, the particle size of nanogels was reduced to ∼25 nm, which facilitated deep penetration of DOX in tumour tissues. After entering tumour cells, the size of nanogels was further reduced to ∼10 nm and DOX was released simultaneously. Meanwhile, FeAlg efficiently catalysed H2O2 to produce •OH by Fenton reaction, achieving local chemodynamic therapy without O2 mediation. Results showed CRGDK-FeAlg/DOX significantly inhibited tumour proliferation in vivo with V/V0 of 1.13 after treatment, significantly lower than that of control group with V/V0 of 4.79.

description: We give a surface integral derivation of the leading-order evolution equations for the spin and energy of a relativistic body interacting with other bodies in the post-Newtonian expansion scheme. The bodies can be arbitrarily shaped and can be strongly self-gravitating. The effects of all mass and current multipoles are taken into account. As part of the computation one of the 2PN potentials parametrizing the metric is obtained. The formulae obtained here for spin and energy evolution coincide with those obtained by Damour, Soffel and Xu for the case of weakly self-gravitating bodies. By combining an Einstein-Infeld-Hoffman-type surface integral approach with multipolar expansions we extend the domain of validity of these evolution equations to a wide class of strongly self-gravitating bodies. This paper completes in a self-contained way a previous work by Racine and Flanagan on translational equations of motion for compact objects.

description: We have found ultraviolet asymptotic slutions of the Schwinger-Dyson equation for the gluon and ghost propagators which have simultaneously the perturbative logarithmic correction and the non-perturbative $1/p^2$ power correction. By including the perturbative corrections, the power correction reproduces exactly the leading OPE result suggesting the existence of dimension two condensate.

description: We present the Gravitational Wave Treasure Map, a tool to coordinate, visualize, and assess the electromagnetic follow-up of gravitational wave (GW) events. With typical GW localization regions of hundreds to thousands of square degrees and dozens of active follow-up groups, the pursuit of electromagnetic (EM) counterparts is a challenging endeavor, but the scientific payoff for early discovery of any counterpart is clear. With this tool, we provide a website and API interface that allows users to easily see where other groups have searched and better inform their own follow-up search efforts. A strong community of Treasure Map users will increase the overall efficiency of EM counterpart searches and will play a fundamental role in the future of multi-messenger astronomy.

description: We theoretically investigate the influence of optical feedback onto the dynamics of a semiconductor swept source laser. In particular, we show that optical feedback can be used to lock the phase of the successive lasing modes of a multi-section semiconductor laser commonly used for Optical Coherence Tomography (OCT) applications. We also identify two different regimes called sliding frequency self-mixing and sliding frequency mode-locking. The second regime demonstrates sub-nanosecond sliding frequency pulses for non-linear optics applications.

title: Cultural Contact in Early Roman Spain through Linked Open Data
Creators: name: Granados-García, Paula Loreto
Publisher: name: The Open University
Year: 2020

description: The study of the Roman colonisation of the western provinces has produced much literature, especially about the processes of assimilation of Roman culture by indigenous communities and the cultural changes experienced by these under Roman influence. In Spain, traditional scholarship has looked mainly at the literary evidence for these processes, and therefore, the ‘Roman’ perspective of the conquest; current schools of thought argue for a new reading of the cultural processes rooted in theory and a contextualised analysis of archaeological data. Traditional methods lacked the tools capable of making effective relationships within large amounts of data. Linked Open Data (hereafter LOD) technologies provide the means to resolve this deadlock. In the last decade, a number of projects have made available large amounts of data leading to a burgeoning of resources that rely on LOD technologies. The number of databases collecting information from Hispania is also continuously increasing. While these resources provide a vast amount of material, most of them do not meet open-access requirements, becoming information silos that hinder information accessibility and interoperability. This research applies LOD technologies to align and connect web-exposed datasets (that follow or can be integrated to follow LOD standards) together with enhanced and aggregated information to investigate the dynamics of cultural interaction in the southern area of Spain between the 4th century BCE and the 1st century CE on the basis of epigraphic, monetary and sculptural evidence. Ultimately, this thesis examines the extent to which the application of LOD technologies can improve the way archaeological information is accessed, retrieved and analysed by means of a LOD dataset (ERUB) and the Cultural Contact Ontology (CuCoO).

title: Unexplored Areas of Teacher Collaboration: Evidence from a Bangladeshi Rural Primary school
Creators: name: Rahman, Md Shajedur
Publisher: name: The Open University
Year: 2020

description: This study investigated how teachers in a rural primary school in Bangladesh understood collaboration, how it was exercised in a daily routine context and the factors that influenced their collaborative activities in a school setting. Teachers’ collaboration in such a Low- and Middle-Income Country (LMIC) context is underexplored. Moreover, collaborative professional development is a policy imperative in this country, and it was assumed that findings of this study may inform teachers, policymakers and teacher educators when designing and implementing School-Based Teacher Development (SBTD) programmes. A Critical Realist (CR) philosophy was adopted which calls for an understanding of the deep social structure and human agency to understand a social event. It allowed an in-depth understanding of the social context of the school and the agency of the teachers. An ethnographic approach adopted in this study helped to obtain authentic data about teachers’ day-to-day collaborative practice in the school context. A range of data collection methods including the audio recording of staffroom conversations, participant observations and interviews was undertaken for two months. A thematic analysis of the data showed that teachers understood collaboration as a matter of their day-to-day activities, which are not restricted to formal professional works but also include a range of informal, professional, social and emotional activities. Teachers were involved in planned and unplanned collaboration with the majority of them being unplanned social conversations. Yet, the collaborative activities seemed to have little impact on teachers’ professional development. Teachers’ understanding of collaboration and the nature of their collaborative activities were very much shaped by the wider culture and organisational norms and regulations. This study concluded that teachers need to be supported to use the collaborative spaces for their professional development. Further research is needed to identify the way teachers can be supported to utilise their collaboration.
An improved multi-ridge fitting method for ring-diagram helioseismic analysis

description: Context: There is a wide discrepancy in current estimates of the strength of convection flows in the solar interior obtained using different helioseismic methods applied to observations from SDO/HMI. The cause for these disparities is not known. Aims: As one step in the effort to resolve this discrepancy, we aim to characterize the multi-ridge fitting code for ring-diagram helioseismic analysis that is used to obtain flow estimates from local power spectra of solar oscillations. Methods: We updated the multi-ridge fitting code developed by Greer et al.(2014) to solve several problems we identified through our inspection of the code. In particular, we changed the merit function to account for the smoothing of the power spectra, model for the power spectrum, and noise estimates. We used Monte Carlo simulations to generate synthetic data and to characterize the noise and bias of the updated code by fitting these synthetic data. Results: The bias in the output fit parameters, apart from the parameter describing the amplitude of the p-mode resonances in the power spectrum, is below what can be measured from the Monte-Carlo simulations. The amplitude parameters are underestimated; this is a consequence of choosing to fit the logarithm of the averaged power. We defer fixing this problem as it is well understood and not significant for measuring flows in the solar interior. The scatter in the fit parameters from the Monte-Carlo simulations is well-modeled by the formal error estimates from the code. Conclusions: We document and demonstrate a reliable multi-ridge fitting method for ring-diagram analysis. The differences between the updated fitting results and the original results are less than one order of magnitude and therefore we suspect that the changes will not eliminate the aforementioned orders-of-magnitude discrepancy in the amplitude of convective flows in the solar interior.
