Subjects: Applied and developmental psychology not elsewhere classified

description: Suicide in prisons remains a critical issue for frontline staff and policy makers, however there are gaps in understanding who, of an already vulnerable population, is at increased risk and why. This thesis explores the relationship between domestic violence perpetration and suicide risk in prisoners, as although such a link has been suggested it has not been investigated in custodial populations. The first study uses template analysis to identify what is known and gaps in knowledge about domestically violent men who died by suicide in prison by analysing Prison and Probation Ombudsman Fatal Incident Reports (FIRs). Drawing from qualitative interviews, the second study uses thematic analysis to explore the experiences ofdomestically violent prisoners who have attempted suicide in prison.Overall the two studies demonstrate that a relationship between domestic violence perpetration and suicide risk exists in a prison population. The first study identified two overarching aspects to FIRs; individual factors and situational and management factors. A key finding was the limited knowledge and understanding of the histories and backgrounds of the men studied within FIRs. However, the study identified potentially important areas of further exploration including how the men experienced relationships, coping skills and their emotional experience. The second study identified five key themes that illustrate the experiences of domestically violent men who have attempted suicide in custody through a sequence or pathway of experiences; Trauma, victimisation and life struggles, Relationship ideals versus relationship reality, Explaining domestic violence, The impact of prison and Suicide as a coping strategy. This thesis concludes that the relationship between domestic violence and suicide risk in prisoners may be better understood by consideration of underlying features of domestic violence perpetrators, such as experiences of trauma, personality psychopathology and attachment. Further exploring pathways to suicide in this population may provide useful insight in the future.
Structured machine learning methods for automated analysis of facial expressions
Creators: name: Walecki, Robert
Publisher: name: Imperial College London
Year: 2018

description: Automated recognition of facial expressions, and detection of facial action units (AUs) from videos depends critically on modeling of their dynamics. Some of these dynamics are characterized by changes in temporal phases (onset-apex-offset) and intensity of emotion expressions and AUs. The appearance of these changes may vary considerably among subjects, making the recognition/detection task very challenging. Recent advances in deep neural networks (DNN) and, in particular, convolutional models have facilitated “end-to-end” learning and reduced or even completely eliminated the dependence and need for physics-based models and/or other pre-processing techniques. While the effect- iveness of these models has been demonstrated on many computer vision problems, only baseline tasks such as expression recognition, AU detection and AU intensity estimation have been investigated. The structure of facial expressions arises from statistically induced co-occurrence patterns of AU intensity levels. Our goal is to model this structure by combining conditional random fields (CRF) with deep learning. The contribution of this thesis is two-fold. First, we introduce a novel Latent-CRF model for classification of image sequences. Second, we propose a deep probabilistic framework for modeling multivariate ordinal variables. Latent-CRFs efficiently encode dynamics through latent states accounting for temporal consistency. These latent states are typically assumed to be either unordered (nominal) or fully ordered (ordinal). Yet, while the video segments containing activation of the target AU may better be described using ordinal latent states (corresponding to the AU intensity levels), the segments where this AU does not occur, may better be described using unordered (nominal) latent states. To address this, we propose the Variable-state L-CRF model that automatically selects the optimal latent states for the target image sequence, based on the input data and underlying dynamics of the sequence. The deep probabilistic framework introduced in the second part of this thesis accounts for ordinal structure in the output variables and their non-linear dependencies via Copula functions modeled as cliques of a CRF. These are jointly optimized with deep CNN feature encoding layers using a newly introduced balanced batch iterative training algorithm. We show that joint learning of the deep features and the target output structure results in significant performance gains compared to existing deep structured models for analysis of facial expressions. We show that the proposed models consistently outperforms (i) independent modeling of AU intensities and (ii) the state-of-the-art approach for the target task and (iii) deep convolutional neural networks.

description: The use of the CCR breathing apparatus for scientific diving at work is relevant for all depth zones depending on the targeted objectives (to approach the wildlife in the river, for behavioural studies of ichthyofauna, to implement sensors or perform core sampling, for eDNA sampling by pumping in the MCE…). The recommendations will have to concern all the profiles of divers, with differentiated parts according to the level of engagement1. Underwater sound measurements of marine life (fishes) used rebreather for a long time (Lobel, 2009), while the exploration of the twilight zone by R.Pyle (Pyle, 1999) highlighted the deep occupational scientific diving work using CCR.

description: We analyse the constraints of an Abelian 2-form gauge theory using Faddeev-Jackiw symplectic formalism. Further, this theory is treated as a constrained system in the context of Batalin-Fradkin-Vilkovisky formalism to retrieve the BRST symmetry. Using the fields decompositions the effective action for Abelian 2-form gauge theory is written in terms of diagonalized uncanonical part and BRST exact one. The nilpotent BRST and contracting homotopy $σ$ closed transformations with field redefinitions are shown as the Darboux transformations used in the Faddeev-Jackiw formalism.

description: The search for the best without the risks has always been part of an investor's investment
 objectives. The need to know the return and the associated risk is very important in an
 investment perspective. The arrival of quantum technology will revolutionize the way we
 analyze and solve complex calculations. Within the financial sector, the performance of this
 technology is already being studied by the major players in order to anticipate future
 deployment. The exploitation of the laws of quantum mechanics will allow a major advance in
 the resolution of problems too complex for classical computers. Its use in finance is called
 "Quantum Finance", and will allow the use of complex mathematical models with large data.
 Thus, this thesis will allow to clarify its impact within our financial sector but also to understand
 the vision of the financial actors.

description: The XENON100 dark matter experiment uses liquid xenon in a time projection chamber (TPC) to measure xenon nuclear recoils resulting from the scattering of dark matter Weakly Interacting Massive Particles (WIMPs). In this paper, we report the observation of single-electron charge signals which are not related to WIMP interactions. These signals, which show the excellent sensitivity of the detector to small charge signals, are explained as being due to the photoionization of impurities in the liquid xenon and of the metal components inside the TPC. They are used as a unique calibration source to characterize the detector. We explain how we can infer crucial parameters for the XENON100 experiment: the secondary-scintillation gain, the extraction yield from the liquid to the gas phase and the electron drift velocity.

description: While in massive galaxies active galactic nuclei (AGN) feedback plays an important role, the role of AGN feedback is still under debate in dwarf galaxies. With well spatially resolved data obtained from the Multi-Unit Spectroscopic Explorer (MUSE), we identify a spatially extended ($\rm \sim 3\; kpc$) and fast ($V_{80} \sim 471\; \rm km\;s^{-1}$) AGN-driven outflow in a dwarf galaxy: SDSS J022849.51-090153.8 with $M_{*} \sim 10^{9.6}\;{\rm M_{\odot}}$ that host an intermediate-mass black hole of $M_{\rm BH} \sim 10^5\;{\rm M_{\odot}}$ and $L_{\rm AGN}/L_{\rm Edd} \sim 0.15$. Through the measurement of the rotation curve, we estimate the escape velocity of the halo and the ratio of the outflow velocity to the halo escape velocity to be $1.09\pm0.04$, indicating that the outflow is capable of escaping not only the galaxy disk but the halo. The outflow size of our AGN is found to be larger than AGN in massive galaxies at the given AGN [O III] luminosity, while the size of the photo-ionized narrow-line region is comparable. These results suggest the important role of AGN feedback through outflows in dwarf galaxies when their central intermediate-mass black holes accrete at high-Eddington ratios.

Repurposing drug scaffolds: a tool for developing novel therapeutics with applications in malaria and lung cancer
Creators: name: Cook, Hannah Elizabeth
Publisher: name: Imperial College London
Year: 2018

description: The definition of repurposing in the context of drug discovery encompasses a variety of strategies designed to redirect current therapeutic knowledge towards new disease indications. This approach can be successful for the design of new drugs to treat diseases of the developing world such as Malaria, where there are limited resources to fund new drug discovery campaigns. Moreover, it can be used to decrease the drug development time for diseases in which there is high drug attrition rates coupled with high mortality rates, which is the case for some cancers. To this end, two separate medicinal chemistry projects are presented herein which are both based on current drug scaffolds originally used for alternative therapeutic indications. The first is the design of an inhibitor of Plasmodium Falciparum Myosin A (PfMyoA), a motor protein implicated in the blood stage invasion of Malaria. Structural predictions of the myosin structure have been made in the form of a homology model using the crystal structure of a well characterised homologue, myosin II and its inhibitor, (S)-Blebbistatin. Plasmodium specific inhibitors were designed in silico based on the structure of (S)-Blebbistatin and synthesised for validation of the model using biological testing of their effect on myosin activity and importantly, on parasite invasion. Interestingly, compounds were found to reduce parasitaemia in red blood cells, independently of PfMyoA, suggesting interaction with an alternative essential myosin. The second project described is the synthesis of compounds that inhibit 90-kDa ribosomal S6 kinase 4 (RSK4), a promotor of lung cancer metastasis and resistance to chemotherapeutic treatments. Inhibitors were synthesised based on the structures of fluoroquinolone antibiotics Moxifloxacin and Trovafloxacin which were identified as moderately potent inhibitors of RSK4. Derivatives were designed with enhanced solubility and tested in a cell-based assay in which 10 novel compounds were identified that inhibit RSK4 activation by at least 50%.

description: We study SUSY models in which Bino contributions solve the muon g-2 anomaly. The contributions are enhanced by large left-right mixing of the smuons. However, it is constrained by the vacuum stability condition of the slepton--Higgs potential. Therefore, there are upper bounds on masses of sleptons and Bino. When the slepton soft masses are universal, the upper bound on the smuon mass becomes 330 (460)GeV in order to solve the g-2 anomaly at the 1 sigma (2 sigma) level. It is within the reach of LHC and ILC. If the stau is heavier than the smuon, the bound can be as large as 1.4 (1.9)TeV. Such non-universal slepton mass spectrum generically predicts too large LFV/CPV. We show that the models are expected to be probed by LHC/ILC and LFV/CPV complementarily in future.

The kinetic Sunyaev-Zel'dovich effect from the diffuse gas in the Local Group

description: Since the Local Group (LG) of galaxies moves with a bulk velocity with respect to the cosmic microwave background radiation (CMB), free electrons in its gaseous halo should imprint large-scale non-primordial temperature shifts in the CMB via the kinetic Sunyaev-Zel'dovich (kSZ) effect. By modeling the distribution of gas in the LG halo and using its inferred velocity with respect to the CMB, we calculate the resulting kSZ signal from the diffuse LG medium. We find that it is dominated by a hot spot $\sim 10^\circ$ in size in the direction of M31, where the optical depth of free electrons is the greatest. By performing a correlation analysis, we find no statistical evidence that the kSZ signal from model of the LG halo is embedded in the CMB temperature map measured by the Planck satellite. We constrain the amount of mass in the LG halo by limiting the kSZ temperature shift around the hot spot to be smaller than the observed temperature shift in the Planck map. We find the tightest constraints for models where the halo mass is highly concentrated, with the mass limited to roughly $2.5-5\times 10^{12}$M$_\odot$, but note that halos with such high concentrations are rare.

description: We investigate several robust preconditioners for solving the saddle-point linear systems that arise from spatial discretization of unsteady and steady variable-coefficient Stokes equations on a uniform staggered grid. Building on the success of using the classical projection method as a preconditioner for the coupled velocity-pressure system [B. E. Griffith, J. Comp. Phys., 228 (2009), pp. 75657595], as well as established techniques for steady and unsteady Stokes flow in the finite-element literature, we construct preconditioners that employ independent generalized Helmholtz and Poisson solvers for the velocity and pressure subproblems. We demonstrate that only a single cycle of a standard geometric multigrid algorithm serves as an effective inexact solver for each of these subproblems. Contrary to traditional wisdom, we find that the Stokes problem can be solved nearly as efficiently as the independent pressure and velocity subproblems, making the overall cost of solving the Stokes system comparable to the cost of classical projection or fractional step methods for incompressible flow, even for steady flow and in the presence of large density and viscosity contrasts. Two of the five preconditioners considered here are found to be robust to GMRES restarts and to increasing problem size, making them suitable for large-scale problems. Our work opens many possibilities for constructing novel unsplit temporal integrators for finite-volume spatial discretizations of the equations of low Mach and incompressible flow dynamics.

The Impact of Organisational Culture on Implementation of Rural Development Strategies in Selected Local Government Authorities in Nigeria
Creators: name: Abdulrahman, Ayotunde
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Regional analysis and development

description: This research examines the impact of organisational culture typologies on current strategy implementation process in Nigerian Local Government Authorities (LGAs). The inefficiency of the current implementation process represents a burden on the lives of the Nigerian citizenry. This problem is examined from an organisational culture perspective. Previous research suggests that aligning organisational culture and strategy implementation produces favourable interrelationships. This research highlights operational implications of these interrelationships. To achieve its objectives, a qualitative case study research is conducted on six Nigerian LGAs using semi-structured interviews (n=60). It epistemologically embedded its research design in the organisational cultural assessment instruments (OCAI) to establish the LGAs contemporary cultural dynamics. The methodical analysis of information exemplifies the interrelationship between its variables and underscores the need for an implementation model which considers various layers of forces existing within and outside the LGAs. A conceptual model with three categories showing interrelationships between the task environment, environmental context and external environment of the LGAs is developed and used as a framework to analyse the data. Findings uncovered the six LGAs adopt a culture mix favourable for their implementation effectiveness. However, key rationalities hindering strategy implementation are closely associated with the ostensible lack of attention to the behavioural patterns of strategic actors. The research provides robust understanding of culture as a determiner of implementation success, and sparks series of novelty thoughts on the impact of culture typologies on strategy implementation practices in Nigerian LGAs. Its practical implications provide public managers with insight into realigning culture and implementation practices to achieve their desired outcome using empirically supported dimensions of the OCAI. The findings of this research suggest the need for future research in examining the recursive and reciprocal effect of culture and implementation in public sector research.
Bilayer graphene with parallel magnetic field and twisting: Phases and phase transitions in a highly tunable Dirac system

description: The effective theory for bilayer graphene (BLG), subject to parallel/in-plane magnetic fields, is derived. With a sizable magnetic field the trigonal warping becomes irrelevant, and one ends up with two Dirac points in the vicinity of each valley in the low-energy limit, similar to the twisted BLG. Combining twisting and parallel field thus gives rise to a Dirac system with tunable Fermi velocity and cutoff. If the interactions are sufficiently strong, several fully gapped states can be realized in these systems, in addition to the ones in a pristine setup. Transformations of the order parameters under various symmetry operations are analyzed. The quantum critical behavior of various phase transitions driven by the twisting and the magnetic field is reported. The effects of an additional perpendicular fields, and possible ways to realize the new massive phases is highlighted.

Exploring the association between worker engagement and safety behaviours
Creators: name: Bell, Nicholas
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Occupational and workplace health and safety

description: This study sought to investigate whether and how worker engagement could facilitate changes in how workers define their work roles to promote behaviours which improve safety. Prior to this research, no single study had investigated the influence of engagement on the full spectrum of safety behaviours nor explained the psychosocial mechanisms involved. This research adopted grounded theory as the methodological framework, leading to an inductive approach. Six qualitative studies were conducted over five years, each of which contributed to the development of the theory and the design of the next study to challenge and refine that theory. They are presented chronologically to show the academic journey of the author and evolution of the theory. These studies include literature reviews, surveys, focus groups and interviews conducted with health and safety professionals and academics. The final study, an interview and focus groups with workers and managers, confirmed that data saturation had been achieved by establishing that the model adequately explained the lived experiences and perceptions of participants. This research makes an original contribution to knowledge by creating a novel and functional psychosocial model of engagement and its association with safety behaviour. The model explains how a process of engagement, which relies on fulfilling the needs of workers, might equip workers with the resources and influence their motivation to integrate protective and/or promotive ‘pro-safety’ norms into one or more role definitions and then invest their resources enacting those norms.The research supported the development of an intervention termed ‘person-centred safety’. This offers a structure for facilitating focus groups to gain insights into levels of engagement in safety and underlying, contributory factors. The research led to a model representing different types of organisational culture that emerged during the research, and overviews of the management training needed to build and sustain engagement within those cultures.

A follow-up observation carried out with the XMM-Newton satellite has provided an X-ray spectrum in the 0.3-10 keV with unprecedented statistics for a GRB afterglow 20 hours after the burst. The spectrum is well fit by a power-law with photon index 1.87+-0.01, modified by absorption in our Galaxy and in the GRB host at z=1.4. A Galactic absorption consistent with that estimated from neutral hydrogen observations is obtained only with host metallicity lower than 0.05 of the Solar value. We report the results of a sensitive search for emission and absorption lines using the matched filter smoothing method (Rutledge and Sako 2003). No statistically significant lines were found. The upper limits on the equivalent width of emission lines, derived through Monte Carlo simulations, are few tens of eV, a factor about 10 lower than that of the possible lines reported in the literature for other bursts.

description: Poor oral hygiene is a severe global health issue, with about 44% of the Earth’s population suffering from untreated tooth decay, accounting for over $100 billion dollars spent on dental services per year in the United States, alone. Manual treatments, such as brushing, flossing, or swishing with antiseptic rinse are the main ways to alleviate harmful bacteria that cause these oral health problems. Streptococcus mutans (S. mutans) is a group of highly antibiotic, Gram-positive bacteria that heavily contribute to oral cavities, plaque build-up, and potential loosening or loss of dental implants if a biofilm develops. Currently, the mechanism for its antibiotic resistant properties is unknown, however, S. mutans cell wall is complex containing multiple peptidoglycan layers of surface glycoploymers, glycerol phosphates, and wall teichoic acids within the polysaccharide shell, providing targets to understanding its biosynthesis pathways. By way of the Conpokal technique, combined atomic force and confocal microscopy, this thesis work determines overall and regional cell wall surface roughness and elastic modulus of three strains of single form S. mutans. Examining a wildtype, a mutant type containing a glycerol phosphate modification, and a complemented genetic control, determining the constituents that contribute to its antibiotic resistance is studied through the link of its mechanical properties to the biological alteration. Greater understanding of S. mutans’ cell wall biosynthesis will aid in regulation of its properties and classification of its antibiotic resistant mechanism.

description: We undertake the investigation of sheared polymer chains grafted on flat surfaces to model liposomes covered with polyethylene glycol brushes as a case study for the mechanisms of efficient drug delivery in biologically relevant situations, for example, as carriers for topical treatments of illnesses in the human vasculature. For these applications, specific rheological properties are required, such as low viscosity at high shear rate to improve the transport of the liposomes. Therefore non - equilibrium, DPD simulations of polymer brushes of various length and shear rates are performed to obtain the average viscosity and friction coefficient of the system as functions of the shear rate and polymerization degree under theta solvent conditions, and find that the brushes experience shear thinning at large shear rates.The viscosity and the friction coefficient are shown to obey scaling laws at high shear rate in theta solvent, irrespective of the brushes degree of polymerization. These results confirm recent scaling predictions and reproduce very well trends in measurements of the viscosity at high shear of red blood cells in a liposome containing medium.

Internet Resource for StartCards: A Method for Early-Stage Software Startups
Creators: name: Kemell, Kai-Kristian
Publisher: name: figshare
Year: 2023
Subjects: Empirical software engineering

description: This figshare address is dedicated to a method for early-stage software startups, StartCards. This method is a card-based method based on scientific and grey literature. The main goal of StartCards is to help early-stage startups avoid common mistakes related to (a lack of) requirements engineering / validation. Here, "early-stage" startup refers to startups working on their product or service concept and those in the early stages of the development process. The cards serve as pointers to existing good practices, such as those in lean startup. The cards are meant to provide motivation and instructions for utilizing the practices. However, they ultimately only contain the basic idea of the practices. For example, the cards contain the basics of creating and utilizing MVPs, but for tips on how to best utilize specific types of MVPs, further reading is encouraged. In this fashion, the cards are intended to familiarize their user with good practices in the context of startups. Each card describes a practice (something that should be done) and there are 14 cards in total. The content on each card is split into three parts: (1) motivation (why this is important), (2) what to do (the activity itself), and (3) common mistakes (to avoid), i.e., the “don’ts”. Additionally, the cards include references to literature as further reading. For example, the references on the MVP card discuss different types of MVPs in more detail. To start using the cards, go over the contents of the cards to evaluate which cards are (still) relevant for your startup. The cards are modular, and thus you should select a card or a number of cards you consider most relevant for your current situation at any given time. In practice, the cards function as checklists for things you should take into account and do. The cards can also be used as an educational tool in practical courses on startup entrepeneurship.

description: In the era of big data, the ubiquity of location-aware portable devices provides an unprecedented opportunity to understand inhabitants' behavior and their interactions with the built environments. Among the widely used data resources, mobile phone data is the one passively collected and has the largest coverage in the population. However, mobile operators cannot pinpoint one user within meters, leading to the difficulties in activity inference. To that end, we propose a data analysis framework to identify user's activity via coupling the mobile phone data with location-based social networks (LBSN) data. The two datasets are integrated into a Bayesian inference module, considering people's circadian rhythms in both time and space. Specifically, the framework considers the pattern of arrival time to each type of facility and the spatial distribution of facilities. The former can be observed from the LBSN Data and the latter is provided by the points of interest (POIs) dataset. Taking Shanghai as an example, we reconstruct the activity chains of 1,000,000 active mobile phone users and analyze the temporal and spatial characteristics of each activity type. We assess the results with some official surveys and a real-world check-in dataset collected in Shanghai, indicating that the proposed method can capture and analyze human activities effectively. Next, we cluster users' inferred activity chains with a topic model to understand the behavior of different groups of users. This data analysis framework provides an example of reconstructing and understanding the activity of the population at an urban scale with big data fusion.

description: A new non-conservative stochastic reaction-diffusion system in which two families of random walks in two adjacent domains interact near the interface is introduced and studied in this paper. Such a system can be used to model the transport of positive and negative charges in a solar cell or the population dynamics of two segregated species under competition. We show that in the macroscopic limit, the particle densities converge to the solution of a coupled nonlinear heat equations. For this, we first prove that propagation of chaos holds by establishing the uniqueness of a new BBGKY hierarchy. A local central limit theorem for reflected diffusions in bounded Lipschitz domains is also established as a crucial tool.

Tidal evolution for any rheological model using a vectorial approach expressed in Hansen coefficients

description: We revisit the two body problem, where one body can be deformed under the action of tides raised by the companion. Tidal deformation and consequent dissipation result in spin and orbital evolution of the system. In general, the equations of motion are derived from the tidal potential developed in Fourier series expressed in terms of Keplerian elliptical elements, so that the variation of dissipation with amplitude and frequency can be examined. However, this method introduces multiple index summations and some orbital elements depend on the chosen frame, which is prone to confusion and errors. Here, we develop the quadrupole tidal potential solely in a series of Hansen coefficients, which are widely used in celestial mechanics and depend just on the eccentricity. We derive the secular equations of motion in a vectorial formalism, which is frame independent and valid for any rheological model. We provide expressions for a single average over the mean anomaly and for an additional average over the argument of the pericentre. These equations are suitable to model the long-term evolution of a large variety of systems and configurations, from planet satellite to stellar binaries. We also compute the tidal energy released inside the body for an arbitrary configuration of the system.

description: This thesis aims to develop an intelligent laparoscope control system composed of a novel foot interface and a shared autonomy framework, which eliminates the need for a human camera holder. The novel foot interface has been shown to provide natural and intuitive control and reduce the user's physical and mental fatigue. The shared control framework gives the surgeon direct control over the laparoscope but automatically adjusts the zoom factor. The case study results show that the proposed intelligent control system is able to lower the surgeons' workload and helps them focus on their hands-on tasks for better performance.

description: The triangular Bose-Hubbard trimer is topologically the minimal model for a BEC superfluid circuit. As a dynamical system of two coupled freedoms it has mixed phase-space with chaotic dynamics. We employ a semiclassical perspective to study triangular trimer physics beyond the conventional picture of the superfluid-to-insulator transition. From the analysis of the Peierls-Nabarro energy landscape, we deduce the various regimes in the $(Ω,u)$ parameter-space, where $u$ is the interaction, and $Ω$ is the superfluid rotation-velocity. We thus characterize the superfluid-stability and chaoticity of the many-body eigenstates throughout the Hilbert space.
