title: A framework for defining and analysing access policies in requirements models
Creators: name: Crook, Robert P.
Publisher: name: The Open University
Year: 2007

description: Enforcing access policies derived from management control principles is a way by which organisations protect their information assets. The minimum privileges principle is an example of a management control principle, which specifies that users should only have access to resources they require to carry out their duties. Requirements models use actors to specify their access policies. Actors normally represent roles that users adopt, however a role can have different meanings, such as a position in an organisation or the assignment of a task, and can therefore be misleading. Current requirements modelling approaches do not provide a systematic way of defining roles for incorporation into access policies, and therefore we can not ensure that they satisfy management control principles. In this thesis we address the need to provide precise role definitions by developing a framework that facilitates the derivation of roles from the organisational context. The framework consists of a metamodel, which enables the organisational context to be represented and related to actors; a set of heuristics for deriving the organisational context; and a set of language constructs for formulating access policies, and verifying them using scenarios. We use the meta-model and language constructs that we developed to extend an existing requirements modelling language, the i* framework, and in particular a formal version of it, formal Tropos, to define and verify access policies definitions satisfying the minimum privileges principle. We also investigate the use of automated tool checking by translating the formal Tropos definitions into the specification language Alloy, which is supported by a tool that automatically checks assertions, to ensure consistency of the access policy definitions. We carry out a detailed case study taken from the literature to verify the extensions to the i* framework and the tool supported analysis. The framework presented in this thesis makes a novel contribution to the modelling of access policies as requirements, enabling us to define access policies using actors derived from the organisational context, that satisfy the minimum privileges principle.

description: High-quality magnetic resonance (MR) image, i.e., with near isotropic voxel spacing, is desirable in various scenarios of medical image analysis. However, many MR acquisitions use large inter-slice spacing in clinical practice. In this work, we propose a novel deep-learning-based super-resolution algorithm to generate high-resolution (HR) MR images with small slice spacing from low-resolution (LR) inputs of large slice spacing. Notice that most existing deep-learning-based methods need paired LR and HR images to supervise the training, but in clinical scenarios, usually no HR images will be acquired. Therefore, our unique goal herein is to design and train the super-resolution network with no real HR ground-truth. Specifically, two training stages are used in our method. First, HR images of reduced slice spacing are synthesized from real LR images using variational auto-encoder (VAE). Although these synthesized HR images are as realistic as possible, they may still suffer from unexpected morphing induced by VAE, implying that the synthesized HR images cannot be paired with the real LR images in terms of anatomical structure details. In the second stage, we degrade the synthesized HR images to generate corresponding LR images and train a super-resolution network based on these synthesized HR and degraded LR pairs. The underlying mechanism is that such a super-resolution network is less vulnerable to anatomical variability. Experiments on knee MR images successfully demonstrate the effectiveness of our proposed solution to reduce the slice spacing for better rendering.

description: Developing tools to automatically detect check-worthy claims in political debates and speeches can greatly help moderators of debates, journalists, and fact-checkers. While previous work on this problem has focused exclusively on the text modality, here we explore the utility of the audio modality as an additional input. We create a new multimodal dataset (text and audio in English) containing 48 hours of speech from past political debates in the USA. We then experimentally demonstrate that, in the case of multiple speakers, adding the audio modality yields sizable improvements over using the text modality alone; moreover, an audio-only model could outperform a text-only one for a single speaker. With the aim to enable future research, we make all our data and code publicly available at https://github.com/petar-iv/audio-checkworthiness-detection.

description: We report the discovery of a dwarf (M_B = -13.9) post-starburst galaxy coincident in recession velocity (within uncertainties) with the highest column density absorber (N_HI = 10^15.85 cm^{-2} at cz = 1586 km/s) in the 3C~273 sightline. This galaxy is by far the closest galaxy to this absorber, projected just 71 kpc on the sky from the sightline. The mean properties of the stellar populations in this galaxy are consistent with a massive starburst ~3.5 Gyrs ago, whose attendant supernovae, we argue, could have driven sufficient gas from this galaxy to explain the nearby absorber. Beyond the proximity on the sky and in recession velocity, the further evidence in favor of this conclusion includes both a match in the metallicities of absorber and galaxy, and the fact that the absorber has an overabundance of Si/C, suggesting recent type II supernova enrichment. Thus, this galaxy and its ejecta are the expected intermediate stage in the fading dwarf evolutionary sequence envisioned by Babul & Rees to explain the abundance of faint blue galaxies at intermediate redshifts.

title: Characterisation of macrophage migration inhibitory factor homologues in plasmodium species
Creators: name: Cordery, Damien Vaughan
Publisher: name: The Open University
Year: 2007

description: Malaria is responsible for 1-3 million deaths per year worldwide, with half the global population at risk of infection. Plasmodium falciparum is the parasite responsible for severe malaria and accounts for almost all fatal cases. The Plasmodium falciparum genome sequencing project identified a putative protein that shares sequence homology with the cytokine macrophage migration inhibitory factor (MIF). MIF has been shown to have a wide range of functions including the modulation of inflammatory responses. The major objective of this project was to characterise the potential MIF homologue in P. falciparum (PfMIF) and to test the hypothesis that this protein may influence the host immune system during the course of P. falciparum infection. Sequence analysis and modelling techniques were used to show that PfMIF shares important structural similarities to other MIF species. Studies of parasites in culture demonstrated that PfMIF mRNA and protein are expressed during ring and trophozoite stages of the parasite life cycle. Furthermore, PfMIF was found to be exported into the cytosol of the infected erythrocyte, and released upon schizont rupture, thus providing an opportunity for PfMIF to interact directly with the host immune system. Recombinant PfMIF protein was generated and used to treat monocytes in vitro. These experiments showed that PfMIF inhibits the random migration and chemotaxis of monocytes and influences surface molecule expression, as evidenced by a decrease in TLR2, TLR4 and CD86. Access to a cohort of children in Kenya allowed examination of patient antibody responses to PfMIF, which showed a pattern of expression similar to antibody responses to other malaria antigens previously examined. In conclusion, these studies suggest that PfMIF could be an important molecule involved in the interaction between the parasite and the host immune system during the course of P. falciparum infection.

description: We present results from extensive numerical simulations on the Lawrence-Doniach model within the lowest Landau level approximation in the unconventional spherical geometry. We study the in-layer pancake vortex density-density correlation function (intra-layer structure factor) and the layer-to-layer order-parameter correlation function along the direction perpendicular to the layers. Our results show strong evidence for the existence of a single first-order phase transition at which both inter-layer coupling and appearance of crystalline order in the in-layer vortex correlations take place as temperature is lowered.

title: Turning a blind eye?: a moral and theological examination of corruption in current Portuguese culture
Creators: name: Fernandes, Fabiano  Lourenco Aleluia
Publisher: name: The Open University
Year: 2007

description: The subject of this thesis is contemporary Portugal from 1974 onwards. The object is corruption. The purpose is to examine the dynamics of both the occurrence of, and impunity to, corruption, as a means of evaluating the quality of democracy and improve it.

Part One (Problem and Awareness Pattern) focusing primarily on the Emaudio case study, the thesis establishes within politics and economics a summative evaluation of the most critical issues heeding to be addressed when dealing with alleged cases of corruption.

Part Two (Cause and Response Pattern) moves beyond a single case study to include both historical and current socio-religious, political and economic contexts of corruption, by exploring critically certain patterns of practice, structures of incentives and opportunities, and perceived cultural assumptions most likely to either nurture or ignore corruption. Three clusters of responses are advanced. They illustrate the inadequate administrative and judiciary responses of the anticorruption agencies, which include a detailed analysis of the Parliament’s Inquiry Commission regarding the dismissal of two deputy directors of the Judicial Police.

Part Three (Tentative Solution Pattern) seeks to develop morally and theologically a means of minimising such corruption and the tendency to ignore it, by formulating an alternative framework which could be used both as a foundation and a starting point (first phase only) for a nationwide, comprehensive, and a multidisciplinary anti-corruption scheme. A classic (10 Great Words) and contemporary (Singapore experience) case study are provided prior to proposing eight principles upon which to base the new anti-corruption alternative response. This follows a tripartite jointly approach of top-down (political will), bottom-up (civil society) and middle-ground (administrative and judiciary) structures.

description: The aim of the paper is to assess the effectiveness of CAP support funds used for co-financing investment projects, which were implemented in the years 2004-2015 by small farms from the Małopolska province in Poland. Studies have shown that the CAP funds supported most often investments for completing and modernizing machinery assets, and construction or modernization of farm buildings. It led to an increase of material resources of these farms, as well as modernization of their production. The research has shown that the effectiveness of using CAP support funds is relatively low. In addition, there is a statistically significant positive correlation between the size of the farm and the efficiency of the use of funds. / Synopsis. Celem artykułu jest ocena efektywności wykorzystania środków pomocowych WPR współfinansujących projekty inwestycyjne, które realizowane były w latach 2004-2015 przez małe gospodarstwa rolne z województwa małopolskiego. Badania wykazały, że gospodarstwa najczęściej wykorzystywały środki pomocowe na realizację inwestycji polegających na uzupełnianiu i unowocześniana swojego parku maszynowego oraz budowie lub modernizacji obiektów gospodarskich, co doprowadziło do powiększenia zasobów rzeczowych tych gospodarstw, a także unowocześnienia prowadzonej w nich produkcji. Badania wykazały stosunkowo niską efektywność wykorzystania środków pomocowych WPR współfinansujących projekty inwestycyjne. Ponadto stwierdzono istnienie istotnej statystycznie, dodatniej zależności między wielkością gospodarstwa, a efektywnością wykorzystania środków.

description: Using clean numerical simulation (CNS) in which artificial numerical noise is negligible over a finite, sufficiently long interval of time, we provide evidence, for the first time, that artificial numerical noise in direct numerical simulation (DNS) of turbulence is approximately equivalent to thermal fluctuation and/or stochastic environmental noise. This confers physical significance on the artificial numerical noise of DNS of the Navier-Stokes equations. As a result, DNS on a fine mesh should correspond to turbulence under small internal/external physical disturbance, whereas DNS on a sparse mesh corresponds to turbulent flow under large physical disturbance, respectively. The key point is that: all of them have physical meanings and so are correct in terms of their deterministic physics, even if their statistics are quite different. This is illustrated herein. Our paper provides a positive viewpoint regarding the presence of artificial numerical noise in DNS.

description: This paper examines the incentives for integration when the market for both consumer durables and supporting or complementary services is oligopolistic. We find that the equilibrium industry structure will depend on the value that consumers place on variety. If the value of additional software is relatively small, the equilibrium industry structure is for both hardware firms to remain unintegrated, while if the value of additional software is relatively large, the equilibrium industry structure is for both hardware firms to integrate. Under the integrated industry structure, profits are lower, less varieties are provided, and hardware prices are lower than under the unintegrated industry structure. The game has a prisoners' dilemma structure when consumers place a high value on the variety of software. This is due to a foreclosure effect. Although consumer surplus is higher under an integrated industry structure, the total surplus associated with the unintegrated industry structure exceeds that of the Integrated industry structure.
Domination, regulation, and resistance: The impact of Aid to Dependent Children and tribal law on White Mountain Apache women, 1934--1960

description: This research analyzes the triple layer of state systems (namely, tribal, state, and federal governments) that culturally and morally dominated and regulated women of the White Mountain Apache Tribe in Arizona between 1934 and 1960. Laws, such as the Aid to Dependent Children program, are cultural expressions of the social group in power. Consequently, dominant white perspectives shape the underlying values and beliefs that guide the tenor and content of legislation. Similarly, the legal codes and constitutions of American Indian nations also define cultural relationships and have been impacted by white conceptions of law. As a historical case study of White Mountain Apache women, the data are based on archival research, which is supplemented by a limited number of consultations with experts in the field of tribal law. The overarching research questions are: How did the dominant society's constructions of race, class, and gender shape the inclusion and exclusion of White Mountain Apache women as they encountered Arizona's Aid to Dependent Children program, what reactions did the women have, and how were they regulated and/or supported by the Tribe's constitution and legal codes?; From 1934 until 1960 a persistent theme in the lives of White Mountain Apache women was the regulatory power of the federal and state governments. By imposing laws on the Tribe, the federal and state governments were able to introduce western cultural symbols and meanings into their society and mold the women (and men) into compliance with the prevailing social configurations. A similar impact was attained by the Aid to Dependent Children program. As the women gained entrance to ADC, they again encountered the regulatory force of the state. Social constructions and meanings surrounding marriage and work were two primary areas targeted by ADC. While ADC was not designed with the purpose of assimilating American Indians, its stigmatization of the poor, enforcement of the work ethic, support for the nuclear family, and legitimization of low-wage labor all worked to weave American Indians deeper into the fabric of American life.

description: The purpose of this study was to investigate the achievement of a cohort of elementary English-language learners on the Virginia Standards of Learning (SOL) tests and to examine a relationship between their test scores and the schools that prepared the students for the tests. According to the hypothesis of this project, it was expected that despite all of the obstacles English-language learners face in the academic setting, SOL test scores increased significantly over time. In addition, it was anticipated that these tests scores could be correlated to schools that are providing an exemplary education for their English-language learners. The Virginia SOL tests have been classified as "high stakes" tests. The impact of the achievement of English-language learners on such "high stakes" tests may ultimately affect school accreditation, funding, curricula, programming, retention rates, professional development, and teacher training. Two data sets were investigated. One data set included student demographic information and two years of SOL test scores. The second data set was the results of an original survey distributed to the principals of the schools that the English-language learners attended. The items on the survey presented questions on school effectiveness for English-language learners. After review, a composite score was calculated for each completed survey. The surveys were ranked and grouped into quartiles for further analysis. Since the research was correlational in nature, descriptive and bivariate correlational statistics were used to analyze the data. Box plots, scatter plots, histograms, Pearson Product Moment correlation coefficient ( r), and linear regression analysis (beta) were used to analyze the data, though neither significance nor correlation was verified. Upon examination of the comparison of the performance rates of the English-language learners and their classmates, it should be noted that both groups made improvements on the SOL subtests, but the English-language learners scored significantly lower.

description: End-to-end reinforcement learning on images showed significant progress in the recent years. Data-based approach leverage data augmentation and domain randomization while representation learning methods use auxiliary losses to learn task-relevant features. Yet, reinforcement still struggles in visually diverse environments full of distractions and spurious noise. In this work, we tackle the problem of robust visual control at its core and present VIBR (View-Invariant Bellman Residuals), a method that combines multi-view training and invariant prediction to reduce out-of-distribution (OOD) generalization gap for RL based visuomotor control. Our model-free approach improve baselines performances without the need of additional representation learning objectives and with limited additional computational cost. We show that VIBR outperforms existing methods on complex visuo-motor control environment with high visual perturbation. Our approach achieves state-of the-art results on the Distracting Control Suite benchmark, a challenging benchmark still not solved by current methods, where we evaluate the robustness to a number of visual perturbators, as well as OOD generalization and extrapolation capabilities.

description: Two flat Randall - Sundrum three-branes are analyzed, at fixed mutual distance, in the case where each brane contains an ideal isotropic fluid. Both fluids are to begin with assumed to obey the equation of state p=(γ-1)ρ, where γis a constant. Thereafter, we impose the condition that there is zero energy flux from the branes into the bulk, and assume that the tension on either brane is zero. It then follows that constant values of the fluid energies at the branes are obtained only if the value of γis equal to zero (i.e., a `vacuum' fluid). The fluids on the branes are related: if one brane is a dS_4 brane (the effective four-dimensional constant being positive), then the other brane is dS_4 also, and if the fluid energy density on one brane is positive, the energy density on the other brane is larger in magnitude but negative. This is a non-acceptable result, which sheds some light on how far it is possible to give a physical interpretation of the two-brane scenario. Also, we discuss the graviton localization problem in the two-brane setting, generalizing prior works.

The kinetic energy, polaron crossover and magnetic transition are investigated as a function of electron-phonon ($e$-ph) coupling and electron concentration for different values of antiferromagnetic superexchange interaction ($J$) between the core spins. The polaron crossover, magnetic transition and the suppression of ferromagnetic transition with $J $ are discussed for the model.

description: Quantum reservoir computing is a computing approach which aims at utilising the complexity and high-dimensionality of small quantum systems, together with the fast trainability of reservoir computing, in order to solve complex tasks. The suitability of quantum reservoir computing for solving temporal tasks is hindered by the collapse of the quantum system when measurements are made. This leads to the erasure of the memory of the reservoir. Hence, for every output, the entire input signal is needed to reinitialise the reservoir, leading to quadratic time complexity. Overcoming this issue is critical to the hardware implementation of quantum reservoir computing. We propose artificially restricting the memory of the quantum reservoir by only using a small number inputs to reinitialise the reservoir after measurements are performed, leading to linear time complexity. This not only substantially reduces the number of quantum operations needed to perform timeseries prediction tasks, it also provides a means of tuning the nonlinearity of the response of the reservoir, which can lead to significant performance improvement. We numerically study the linear and quadratic algorithms for a fully connected transverse Ising model and a quantum processor model. We find that our proposed linear algorithm not only significantly reduces the computational cost but also provides an experimental accessible means to optimise the task specific reservoir computing performance.

We show that, upon an appropriate choice of the interaction potential, one of the scalar fields behaves like dark energy, inducing a late-time accelerated expansion of the universe, while the other scalar field behaves like pressureless dark matter that, together with ordinary baryonic matter, dominates the intermediate phases of cosmic evolution. This unified description of dark energy and dark matter gives rise to viable cosmological solutions, which reproduce the main features of the evolution of the universe.

The effect of narcissistic, dependent, compulsive, and antisocial personality traits on treatment outcome for Axis I symptoms
Creators: name: Meyer, Carmen Marie
Publisher: name: American University
Year: 2023

description: The relationship between Narcissistic, Compulsive, Dependent, and Antisocial personality traits, as measured by the MCMI-III, and the clinical presentation and treatment outcome for Axis I symptoms, as measured by the MMPI-2 was investigated. The subjects were 86 Roman Catholic priests and nuns who participated in six to eight months of residential treatment. Pre-treatment evaluation of the patients included the MCMI-III and the MMPI-2. Clinical presentation of Axis I disorders was measured by pre-treatment scores on MMPI-2 scales 2 (Depression), 7 (Psychasthenia), content scale DEP (Depression), and content scale ANX (Anxiety). Treatment outcome was measured by the post-treatment MMPI-2 scores on these four variables. The mean post-treatment scores on the four MMPI-2 variables were significantly lower than the mean pretreatment scores. MCMI-III scores on Narcissistic were found to account partly for the variance in pre-treatment MMPI-2 scores on Scales 2 and 7. Narcissism and Compulsive personality scale scores were found to account partly for the variance on Content Scale DEP, and Dependent scale scores were found to account partly for the variance on Content Scale ANX. The forty-eight patients with MCMI-III BR scores above 74 had significantly higher pre-treatment MMPI-2 scores than the patients with lower MCMI-III scores. There were no other differences found between these two groups. Narcissism was found to account partly for the variance of MMPI-2 change scores on the MMPI-2 scale 2. These results are inconsistent with previous studies that concluded that personality dysfunction has an adverse impact on treatment outcome for Axis I disorders. The intensive individual and group therapy, extended length of stay, and emphasis on community living that the residential program provides may account for these results.

description: An experiment was conducted at the Horticulture Farm of the Bangladesh Agricultural University, Mymensingh during the period from July 2003 to January 2004. The objectives of the study was to examine the influence of set sizes including whole and cut pieces in order to develop a low—cost technology for onion production. The results of the experiment revealed that bulb yield increased with the increase .in bulb size with proportionate increase in the production cost. Cut bulbs treated with ash had no effect on yield of onion bulbs. The yield of plants raised from whole bulbs was higher than that raised from cut bulbs irrespective of size. Small whole bulbs were more profitable for commercial onion production followed by very small whole bulb and cut pieces from large bulbs.

description: Additional file 9 Fig. S4. Analysis of concordance among motifs predicted by QGRS Mapper, low-threshold G4 Hunter and experimental G4 seq in the P. falciparum 3D7 genome. Venn diagrams show overlaps between PQS sequences detected by QGRS Mapper, G4 Hunter and experimental G4-seq. The concordance analysis was performed with data from G4 Hunter at two different thresholds: the more stringent threshold of 1.7 was used in Fig. 9 B and C, whereas a threshold of 1.25 is depicted here. For G4-seq data, For G4-seq data, PQSs within 20 kb of chromosomal ends were considered telomeric. Due to the size of the G4-seq windows, it was possible for multiple PQSs to fall within the same window. Numbers in parentheses show the “full” count of PQSs detected within G4-seq windows, while numbers not in parentheses show the number of unique G4-seq windows that contained at least one PQS.

description: We report on the results of the spectral and timing analysis of a BeppoSAX observation of the microquasar system LS 5039/RX J1826.2-1450. The source was found in a low-flux state with Fx(1-10 keV)= 4.7 x 10^{-12} erg cm^{-2} s^{-1}, which represents almost one order of magnitude lower than a previous RXTE observation 2.5 years before. The 0.1--10 keV spectrum is described by an absorbed power-law continuum with photon-number spectral index Gamma=1.8+-0.2 and hydrogen column density of NH=1.0^{+0.4}_{-0.3} x 10^{22} cm^{-2}. According to the orbital parameters of the system the BeppoSAX observation covers the time of an X-ray eclipse should one occur. However, the 1.6-10 keV light curve does not show evidence for such an event, which allows us to give an upper limit to the inclination of the system. The low X-ray flux detected during this observation is interpreted as a decrease in the mass accretion rate onto the compact object due to a decrease in the mass-loss rate from the primary.

title: Cosmological motifs and themes in the Odyssey of Homer, with some antecedents in Minoan and Mycenaean iconography
Creators: name: Hammond, Rosemary Margaret
Publisher: name: The Open University
Year: 2007

description: It is argued that the symbolism of Homer’s Odyssey, preserves and perpetuates an inter-textual layer of metaphoric reference from which it is possible to reconstruct some of the religious and political ideology of the late Bronze Age Aegean. The epic literature, to some extent a guardian to the oral history of Minoan Crete and the Mycenaean sphere of influence, has been ‘decoded’ and placed in context by the use of stabilising comparanda,. These are drawn from a universal myth, supplemented by Near Eastern ritual and belief. The ancient, worldwide imagery of the axis mundi and omphalos,, ‘navel of the earth’, has provided an essential common denominator for the measurement and assessment of the epic discourse as well as surviving art and architecture.
 The resultant evidence reveals that the poet held to cosmological and cosmogonic beliefs that envisaged a single creative source manifesting itself to man in the patterns of nature, including those of man’s own form and intelligence. That source, the Absolute, holds heaven and earth in a linear bond which replicates into duality, then expands beyond into multiple forms. This vertical link is expressed most traditionally by a cosmic tree, pillar, mountain, staff or sceptre, and the earth’s receptive point, the omphalos, appears as a stone, a cave, a throne or a bed. The ‘navel point, centre of the world’, is man’s gateway to immortality. This important concept of a divine ‘Centre’ marking the point of access to the axial power provides not only considerable thematic material of Aegean architectural, glyptic and fresco design in the late second millennium BC, but also determines the course of Odysseus’ Adventures, which are analysed anew in this study as stages in a spiritual journey along a solar course of departure and return, to and from that same transformative centre.

description: A pot experiment was carried out at the Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh, to evaluate salinity tolerance of mustard/rapeseed cultivars viz., BINAsarisha-5, BINAsarisha-6 and Safal during October 2003 to January 2004. Salinity levels were 4, 6, 8 and 10 dSrnwith a control (0.43 dSm ). Plant height, leaf area, total dry matter, number of siliqua per plant, number of seeds per siliqua, 1000-seed weight and harvest index were decreased with the increase of salinity compared to control. Na + content in leaves increased but K+content decreased with the increase orsalinity. BINAsarisha-6 showed the highest number of siliqua, seed yield per plant, harvest index, higher Na + and medium K+ content in leaves and BINAsarisha-5 showed the highest number of seeds per siliqua, 1000-seed weight, lower Na + and higher K+ content in leaves under the salinity levels. On the other hand, Safal showed the lowest number of seeds per siliqua, seed yield, higher Na + and the lowest K+ content in leaves. BINAsarisha-6 and B1NAsarisha-5 were found to be tolerant and Safal was less tolerant to imposed salinity.

description: We demonstrate the controlled incorporation of P dopant atoms in Si (001) presenting a new path toward the creation of atomic-scale electronic devices. We present a detailed study of the interaction of PH3 with Si (001) and show that it is possible to thermally incorporate P atoms into Si (001) below the H desorption temperature. Control over the precise spatial location at which P atoms are incorporated was achieved using STM H-lithography. We demonstrate the positioning of single P atoms in Si with ~ 1 nm accuracy and the creation of nanometer wide lines of incorporated P atoms.
