title: A case study exploring the impact of parental deployment on the wellbeing of British Army children in the pre-school year
Creators: name: Normile, G
Publisher: name: Bath Spa University
Year: 2020

description: This thesis explores the wellbeing of three to four-year-old British Army children experiencing a parental deployment during their pre-school year. Despite a recent increase in interest of the deployment-related experiences of school-aged service children, the deployment-related wellbeing of pre-school children has been under researched in the British context and they remain overlooked in terms of educational, social and Armed Forces policy.This study also seeks to clarify the use of the conceptually vague term wellbeing in the context of service children’s research through a consideration of the multiple discourses of wellbeing and an exploration of the component domains of wellbeing. Drawing upon both the bioecological model of development and cultural historical theory, the study explored how individual, social and environmental factors impact upon the different domains of pre-school children’s wellbeing during a parental deployment. A case study design focusing on ten children experiencing a parental deployment was employed within an Army Garrison in England.In each case, the deployed parent was the father.Interviews were conducted with the ten non-deployed mothers and fourteen pre-school practitioners working with the children. Six of the pre-school children also took part in the study via participatory research methods and interviews. Analysis of the data identified four distinct but interlinked domains of wellbeing that were impacted by the father’s deployment; psychological, physical, social and cognitive. These are discussed in relation to how they are influenced by factors of the individual child, their social relationships and factors relating to their environments. The thesis concludes by discussing the implications of this research for British educational, social and Armed Forces policy and practice in terms of supporting the wellbeing of pre-school children during times of a parental deployment.

title: Using creative writing to explore identity formation: a participatory study with adolescents in post-conflict Colombia
Creators: name: Fuentes Díaz, C
Publisher: name: Bath Spa University
Year: 2020

description: This thesis explores Colombian adolescents’ identity formation through a creative writing programme within a school context. This research investigates how this programme aids the exploration of adolescents’ identity formation focusing on the youth participants’ perceptions, as well as on the identity formation aspects they portray in their creative writing. Underpinned by social constructionism, this study stands on the ontological premise that social interaction precedes the construction of knowledge, and places language at the centre of identity formation. In particular, this study uses Dan McAdams’ narrative identity theory and Kenneth Gergen’s concept of relational being as key conceptual schema. The fieldwork took place in a public school in Colombia and lasted for 19 weeks. Fifteen ninth grade participants (14-16 year-old students; or equivalent of UK Year 11) volunteered, eleven women and four men. The research design was built upon a participatory mixed qualitative research design, which joined methods from arts-based research, educational practice and the social sciences. The six creative writing workshops were designed within a project-based learning structure and were complemented by more established qualitative research techniques like interviews and focus groups. The book, together with the interviews and the participants’ reflective narratives on the process, were chosen as the main data for analysis. The findings highlight the fact that creative writing programmes aid identity formation by providing opportunities for authentic self- expression. The role of the researcher as a facilitator is highlighted. The adolescents’ creative writing reveals identity is constructed around trust and the constant negotiation of inner emotions with outer expressions of the self. The findings evidence implications for research design, data use and analysis and educational practice. Most importantly, this research argues for shifting the focus to authentic expressions of identity (versus notions of positive identity), by valuing agency in mid-adolescents.

description: Recent ASCA spectra exhibit discrepancies with the relative line intensities of various Fe XXIII and XXIV L-shell emission lines predicted by standard plasma emission codes. To address this issue, we have carried out a series of high-resolution, broadband measurements of Fe XXIV line emission using an electron beam ion trap facility. X-ray lines produced in the trap are detected and resolved using Bragg crystal spectrometers. We report measurements of 3 → 2 and 4 → 2 transitions, which result primarily from electron impact excitation. Overall, good agreement is found with distorted wave calculations.
Towards comprehensive interpretation of the state parameter from cone penetration testing in cohesionless soils
Creators: name: Ghafghazi, Mohsen
Publisher: name: University of British Columbia
Year: 2011

description: The Cone Penetration Test (CPT) is widely used for determining in-situ properties of soil because of its continuous data measurement and repeatability at relatively low cost. The test is even more attractive in cohesionless soils such as sands, silts and most tailings due to difficulties associated with retrieving undisturbed samples in such soils. Behaviour of soils is highly dependent on both density and stress level. The state parameter is widely accepted to represent the soil behaviour encompassing both density and stress effects. Hence, determining the in-situ state parameter from CPT is of great practical interest. The CPT was analysed using a large strain spherical cavity expansion finite element code using a critical state soil model (NorSand) capable of accounting for both elasticity and plastic compressibility. The constitutive model was calibrated through triaxial tests on reconstituted samples. The state parameter was then interpreted from CPT tip resistance, and the results were verified against an extensive database of calibration chamber tests. The efficiency of the method was further investigated by analysing two well documented case histories confirming that consistent results could be obtained from different in-situ testing methods using the proposed framework. Consequently, cumbersome and expensive testing methods can be substituted by a combination of triaxial testing and finite element analysis producing soil specific correlations. One of the difficulties in analysing the cone penetration problem is the less researched effect of high stresses developing around the cone on the behaviour of the soil. A hypothesis was put forward on the particle breakage process at the particle level and its implications for the behaviour of sands at higher stress levels were discussed. A series of triaxial tests were performed, focusing on the effects of particle breakage on the location of the critical state line. The hypothesis was used to explain the observed behaviour. Particle breakage was shown to cause additional compression and a parallel downward shift in the critical state line. The magnitude of the shift was linked to the amount of breakage and it was argued that significant breakage starts after the capacity for compression due to sliding and rolling is exhausted.
Cell Autonomous and Cell Non-Autonomous Roles of p75 Neurotrophin Receptor (p75NTR) in Glioblastoma Progression

description: Glioblastoma multiforme (GBM) is the most common and aggressive brain tumor that is inevitably a fatal disease. GBM is a heterogeneous tumor consisting of tumor cells and a small population known as brain tumor initiating cells (BTICs) or glioblastoma stem-like cells. BTICs appear to drive tumor progression, underlie therapeutic resistance to current treatment and tumor relapse and have been highlighted as important therapeutic targets. The ability of glioma cells to invade into the surrounding brain parenchyma is a major clinical issue rendering glioblastoma incurable by conventional therapies. Using a large panel of GBM cells including genetically different patient-derived-BTICs we have investigated the cell autonomous and cell non-autonomous roles of p75NTR in GBM progression. Immunohistochemical studies and western blot analyses demonstrated that p75NTR is variably expressed on BTICs. Loss-of-function and gain-of-function studies of p75NTR revealed that p75NTR is involved in regulating self-renewal, proliferation, cell cycle progression, symmetry and asymmetry cell divisions, apoptosis, differentiation and invasion of genetically different patient-derived BTICs. Furthermore, loss-of-function of p75NTR in these BTICs inhibited their tumorigenic behaviors in vivo and extended the survival time of mice bearing brain tumors generated by p75NTR knockdown BTICs compared to their control counterparts. In addition to the cell autonomous roles of p75NTR in regulating GBM progression, this thesis provided novel findings about the cell non-autonomous roles of p75NTR in mediating glioma invasion. We further demonstrated that p75NTR is transferred between glioma cells through extracellular vesicles (EVs) to induce invasive properties in recipient glioma cells. Interestingly, proteolytic processing of p75NTR was detected in EVs and was required for meditating glioma cell invasion by p75NTR-containing EVs, as EVs isolated from glioma cells expressing a cleavage-resistant chimera of p75NTR (p75Fas-S) or from cells treated with a γ-secretase inhibitor failed to induce glioma cell invasion. p75NTR was also found in EVs isolated from sera of mice bearing brain tumors generated by p75NTR-expressing BTICs. These data highlight a previously unknown function of this receptor and suggest it may be a novel therapeutic target in the treatment of this devastating cancer.

description: There is limited information on influenza and respiratory syncytial virus (RSV) seasonal patterns in tropical areas, although there is renewed interest in understanding the seasonal drivers of respiratory viruses. We review geographic variations in seasonality of laboratory-confirmed influenza and RSV epidemics in 137 global locations based on literature review and electronic sources. We assessed peak timing and epidemic duration and explored their association with geography and study settings. We fitted time series model to weekly national data available from the WHO influenza surveillance system (FluNet) to further characterize seasonal parameters. Influenza and RSV activity consistently peaked during winter months in temperate locales, while there was greater diversity in the tropics. Several temperate locations experienced semi-annual influenza activity with peaks occurring in winter and summer. Semi-annual activity was relatively common in tropical areas of Southeast Asia for both viruses. Biennial cycles of RSV activity were identified in Northern Europe. Both viruses exhibited weak latitudinal gradients in the timing of epidemics by hemisphere, with peak timing occurring later in the calendar year with increasing latitude (P<0.03). Time series model applied to influenza data from 85 countries confirmed the presence of latitudinal gradients in timing, duration, seasonal amplitude, and between-year variability of epidemics. Overall, 80% of tropical locations experienced distinct RSV seasons lasting 6 months or less, while the percentage was 50% for influenza. Our review combining literature and electronic data sources suggests that a large fraction of tropical locations experience focused seasons of respiratory virus activity in individual years. Information on seasonal patterns remains limited in large undersampled regions, included Africa and Central America. Future studies should attempt to link the observed latitudinal gradients in seasonality of viral epidemics with climatic and population factors, and explore regional differences in disease transmission dynamics and attack rates.

description: Blebs are balloon-shaped membrane protrusions that form during many physiological processes. Using computer simulation of a particle-based model for self-assembled lipid bilayers coupled to an elastic meshwork, we investigated the phase behavior and kinetics of blebbing. We found that blebs form for large values of the ratio between the areas of the bilayer and the cytoskeleton. We also found that blebbing can be induced when the cytoskeleton is subject to a localized ablation or a uniform compression. The results obtained are qualitatively in agreement with the experimental evidence and the model opens up the possibility to study the kinetics of bleb formation in detail.

description: A distinctive approach for forming a lateral Bipolar Charge Plasma Transistor (BCPT) is explored using 2-D simulations. Different metal work-function electrodes are used to induce n- and p-type charge plasma layers on undoped SOI to form the emitter, base and collector regions of a lateral NPN transistor. Electrical characteristics of the proposed device are simulated and compared with that of a conventionally doped lateral bipolar junction transistor with identical dimensions. Our simulation results demonstrate that the BCPT concept will help us realize a superior bipolar transistor in terms of a high current gain compared to a conventional BJT. This BCPT concept is suitable in overcoming doping issues such as dopant activation and high-thermal budgets which are serious issues in ultra thin SOI structures.

description: On its current economic trajectory, India will achieve some of the eight Millennium Development Goals, but will miss many of the others. The good news is that India is making great strides with regard to the first of the Millennium Development Goals: reducing extreme poverty. Even though there is an active debate about the "exact" measure of extreme poverty, all indicators suggest rapid progress, enough on the current trajectory so that the headcount poverty rate in 2015 will be less than half of the rate in 1990, as called for by the Millennium Development Goals. At the same time, India is likely to miss several of the other goals, related to hunger, IMR, under-5, and MMR, disease, and the physical environment. The proportion of children in India who are chronically undernourished remains very high. So too does the MMR and IMR. And the goal of environmental sustainability is not being achieved, as parts of India are suffering from worsening crises of water, soils, and deforestation. What India requires is a significant increase of targeted investments in clinics, schools, nutrition programs, disease control, irrigation, rural electrification, rural roads, and other basic investments, especially in rural India as the current budgetary allocations are inadequate. Higher public investments in these areas need to be accompanied by systemic reforms that will help overhaul the present system of service delivery, including issues of control and oversight. Additionally, India should "plan for success." The Planning Commission should ensure that current programs as well as the next Five-Year Plan are built around achieving the Millennium Development Goals. Indeed, not only the Union Government, but every state and even every district, should base their investment programs around achieving the Millennium Development Goals.

description: Chemical fractionation of the ethanolic extract of the roots of Isatis tinctoria L. (I. tinctoria) yielded fourteen indole alkaloids including four new ones, isatisindigoticanine L–N and isatindigoside M. Their structures were established on the basis of extensive spectroscopic techniques including NMR, HRESIMS and IR as well as chemical methods. The absolute configuration of 1 was confirmed by ECD experiments. All the compounds were tested for their inhibitory effects on NO production in mouse mononuclear macrophages (RAW264.7) induced by lipopolysaccharide (LPS). The results showed that only compound 5 exhibited inhibitory effects with IC50 value of 18.5 μM.

I remark that (1) there is no Z_2 symmetry apparent in the lepton mass spectrum and in lepton mixing, (2) predictive models of this type may be constructed by using a lepton flavour symmetry group with three inequivalent singlets, to which the three left-handed-lepton gauge-SU(2) doublets are assigned, and (3) some predictions for the lepton masses and mixings are likely to be altered by radiative contributions to the neutrino mass matrix. I construct two models of this type in which the conserved Z_2 originates in a lepton flavour symmetry group D_4.

description: Conventional firewalls rely on topology restrictions and controlled network entry points to enforce traffic filtering. Furthermore, a firewall cannot filter traffic it does not see, so, effectively, everyone on the protected side is trusted. While this model has worked well for small to medium size networks, networking trends such as increased connectivity, higher line speeds, extranets, and telecommuting threaten to make it obsolete. To address the shortcomings of traditional firewalls, the concept of a "distributed firewall" has been proposed. In this scheme, security policy is still centrally defined, but enforcement is left up to the individual endpoints. IPsec may be used to distribute credentials that express parts of the overall network policy. Alternately, these credentials may be obtained through out-of-band means. In this paper, we present the design and implementation of a distributed firewall using the KeyNote trust management system to specify, distribute, and resolve policy, and OpenBSD, an open source UNIX operating system.

description: Quantum information systems require an interface between photons as a physical system to transport information and atoms which are better suited to store and process it. In this thesis the construction of a novel pulsed, bright and narrow-band light source is presented. It consists of an optical parametric oscillator featuring a periodically poled KTP crystal and a mechanical chopper and produces ?s-pulses of squeezed vacuum. The generated states are resonant to the Rubidium-DI-transition, are almost transform-limited and show more than 3 dB of squeezing. The physical effect of electromagnetically induced transparency (EIT) in hot rubidium vapor can be used to generate ultra-low group velocities and allows for a reversible adiabatic conversion of optical quantum states into collective spin excitations which can be used to stop pulses of light. I report about recent progress in slowing down a pulse of squeezed vacuum by one third of its width while still preserving 0.36 dB of squeezing in the process. I analyze electromagnetically induced transparency and light storage in an ensemble of atoms with multiple excited levels (multi-A configuration) which are coupled to one of the ground states by quantized signal fields and to the other one via classical control fields. A basis transformation of atomic and optical states which reduces the analysis of the system to that of electromagnetically induced transparency in a regular three-level configuration is presented. We demonstrate the existence of dark state polaritons and propose a protocol to transfer quantum information from one optical mode to another by adiabatic control of the control fields and present a proof-of principle experiment to adiabatically transfer light between modes of different frequencies in Rb-87 vapor. To that end a digital phase lock circuit has been designed that allows to electronically phase lock an external-cavity diode laser to a reference laser over a 7 GHz frequency range with sub-Hertz precision.

description: An evolution-based algorithm is applied to comprehensively optimize a field scale reservoir developing process, spanning from the primary production to the waterflooding and then the miscible water-alternating-CO2 (CO2 WAG) process. Effects of 98 operational parameters on the net present value (NPV) are analyzed and quantified, including the primary production duration, water injection rates during the waterflooding process, process onset time, gas and water injection rates of CO2 WAG process and producer bottomhole pressure (BHP) during each production stage. The impacts of geological uncertainty are evaluated using multiple reservoir realizations. It has been found that durations of the primary production and waterflooding processes have the most pronounced impact on the final NPV. The oil recovery of the comprehensive optimization scenario has been enhanced by 23.37% compared to that of the conventional WAG optimization. This is mainly due to the shorter durations of the primary and waterflooding processes.

description: Variability of the Indian summer monsoon is decomposed into an interannually modulated annual cycle (MAC) and a northward-propagating, intraseasonal (30–60-day) oscillation (ISO). To achieve this decomposition, we apply multi-channel singular spectrum analysis (M-SSA) simultaneously to unfiltered daily fields of observed outgoing long-wave radiation (OLR) and to reanalyzed 925-hPa winds over the Indian region, from 1975 to 2008. The MAC is essentially given by the year-to-year changes in the annual and semi-annual components; it displays a slow northward migration of OLR anomalies coupled with an alternation between the northeast winter and southwest summer monsoons. The impact of these oscillatory modes on rainfall is then analyzed using a 1-degree gridded daily data set, focusing on Monsoonal India (north of 17°N and west of 90°E) during the months of June to September. Daily rainfall variability is partitioned into three states using a Hidden Markov Model. Two of these states are shown to agree well with previous classifications of "active" and "break" phases of the monsoon, while the third state exhibits a dipolar east–west pattern with abundant rainfall east of about 77°E and low rainfall to the west. Occurrence of the three rainfall states is found to be an asymmetric function of both the MAC and ISO components. On average, monsoon active phases are favored by large positive anomalies of MAC, and breaks by negative ones. ISO impact is decisive when the MAC is near neutral values during the onset and withdrawal phases of the monsoon. Active monsoon spells are found to require a synergy between the MAC and ISO, while the east–west rainfall dipole is less sensitive to interactions between the two. The driest years, defined from spatially averaged June–September rainfall anomalies, are found to be mostly a result of breaks occurring during the onset and withdrawal stages of the monsoon, e.g., mid-June to mid-July, and during September. These breaks are in turn associated with anomalously late MAC onset or early MAC withdrawal, often together with a large-amplitude, negative ISO event. The occurrence of breaks during the core of the monsoon—from late July to late August—is restricted to a few years when MAC was exceptionally weak, such as 1987 or 2002. Wet years are shown to be mostly associated with more frequent active spells and a stronger MAC than usual, especially at the end of the monsoon season. Taken together, our results suggest that monthly and seasonal precipitation predictability is higher in the early and late stages of the summer monsoon season.

description: Recently there has been much interest in "sparsifying" sums of rank one matrices: modifying the coefficients such that only a few are nonzero, while approximately preserving the matrix that results from the sum. Results of this sort have found applications in many different areas, including sparsifying graphs. In this paper we consider the more general problem of sparsifying sums of positive semidefinite matrices that have arbitrary rank. We give several algorithms for solving this problem. The first algorithm is based on the method of Batson, Spielman and Srivastava (2009). The second algorithm is based on the matrix multiplicative weights update method of Arora and Kale (2007). We also highlight an interesting connection between these two algorithms. Our algorithms have numerous applications. We show how they can be used to construct graph sparsifiers with auxiliary constraints, sparsifiers of hypergraphs, and sparse solutions to semidefinite programs.
Preliminary guidelines for manual annotation of word senses in Latin and ancient Greek corpora

description: This collection consists of two documents: File “Guidelines.PDF”: this document contains the preliminary guidelines for manual annotation of word senses in Latin and ancient Greek corpora. These guidelines were conceived within the project ‘A new CLARIN Resource Family for lexical semantic change research’ between November 2022 and June 2023, funded by CLARIN-ERIC. The project team includes Paola Marongiu (researcher) and is led by Barbara McGillivray (King’s College London) in collaboration with Fahad Khan (ILC-CNR). File “wordlist_latinise_4.xlsx”: this spreadsheet contains data and corpus analysis of wordlists extracted from the Latin corpus LatinISE, version 4 (McGillivray & Kilgarriff 2013). This analysis can be used to estimate the corpus frequency counts of various wordlists and the proportion of the total corpus frequency counts of all Latin lexical words (nouns, verbs, adjectives, and adverbs). a. Tab “LatinISE_word_frequency_list”: contains the list of all LatinISE lemmas (column B) with their frequencies (column A). Additional columns indicate whether the lemma appears in one of the other wordlists (see b., c., d., and g.). b.Tab “LWN_lemmas” contains the unique list of lemmas from the version of Latin WordNet (LWN) manually corrected by the LiLa project (Litta et al. 2013). c.Tab “100_frequent_words” contains a manual selection of 100 lemmas with high frequency in LatinISE. d.Tab “100_medium_frewuency_words” contains a manual selection of 100 lemmas with medium frequency in LatinISE. e.Tab “frequency_estimates” contains a summary of the frequencies of the different word lists in LatinISE. f.Tab “frequency_list_pos” contains the frequency counts of each part-of-speech in LatinISE. g.Tab “selected_wordlists” contains manually curated lists of Latin medical terms, legal terms, and lemmas from the lexical fields of Writing and Body Parts.

description: Global Services Sourcing (GSS) is not an original concept. What is original about it is the media attention it seems to be getting. We have adopted the "then and now" philosophy in developing this report. We start by talking to the pioneers of global services sourcing, companies like General Electric, Nortel Networks and Citibank. The key learning from talking to these companies who have been sourcing their processes for more than a decade is that the long held view -- "went for cost, stayed for quality" about moving processes outside the company (in some cases outside the country) is too simplistic. Rather we found that "went for cost and quality, stayed for continued quality at competitive costs" is more in line with the strategy that that these companies employed. Next, our in depth questionnaire tries to capture the "now" of the global services sourcing industry. Since the pioneers had shone the arc light on quality we developed specific quality related questions. The results validated the pioneers' views: Of the companies that are engaged in services sourcing, 79% of respondents were using an offshore based provider. Perhaps in a sign of maturing of global services sourcing 62% chose to offshore their services to at least one country in addition to India, the current offshoring destination of choice. As far as country risk factors, legal risks (laws comparable to international standards - data security, intellectual property rights) followed by political risks were identified as the top areas of concern. The lesson for countries competing for offshored business and FDI inflows in services is that the robustness and fairness of the legal system is a major factor for companies especially in the face of concerns about loss of institutional knowledge. The overall satisfaction level with outsourcing was high at 68% but a sizeable chunk of respondents -- 26% were either unsatisfied or very unsatisfied with their outsourcing arrangements. Almost all of these unsatisfied firms have been outsourcing for 12 months or less, reinforcing the literature about thinking of outsourcing being a long term investment rather than a short term win.

description: We present a procedure to solve the inverse Ising problem, that is to find the interactions between a set of binary variables from the measure of their equilibrium correlations. The method consists in constructing and selecting specific clusters of variables, based on their contributions to the cross-entropy of the Ising model. Small contributions are discarded to avoid overfitting and to make the computation tractable. The properties of the cluster expansion and its performances on synthetic data are studied. To make the implementation easier we give the pseudo-code of the algorithm.
