title: AN APPRAISAL OF THE DEVELOPMENTS IN THE REPRODUCTION OF COLOUR IN COMPUTER PUBLISHING SYSTEMS
Creators: name: Osmond, Matthew Richard
Publisher: name: The Open University
Year: 1995

description: The plethora of coloured images that are reproduced in any printed media is facilitated through a variety of related processes that collectively constitute traditional printing techniques. The aim of this research is to appraise recent developments that have occurred within the colour prepress process. The colour prepress process involves the preparation of colour separated halftone films that are used in the production of offset lithographic printing plates. Over recent years the application of desktop publishing technology to perform many of the functions associated with the colour prepress process has raised a number of significant issues and debates. The reproduction of coloured images in the printed medium demands that certain fundamental criteria are adhered to in order to maintain professional standards of colour fidelity. Such criteria include: successful digital halftone production, the elimination of moiré patterns, and maintaining colour fidelity between the coloured original and the coloured reproduction. This research thesis shall therefore establish the principles and techniques involved in the reproduction of colour in a printed medium. It will also asses whether desktop publishing systems are able to facilitate successful professional colour reproduction by examining current debates that challenge the viability of desktop publishing solutions. Current debates concerning desktop publishing solutions are primarily concerned with assessing the value of Adobe PostScript level 2 solutions, computer interchange spaces for colour matching purposes, and rational supercell techniques that attempt to eliminate moiré patterns. The research also attempts to establish the validity of current debate findings by comparing them with statistics derived hom a questionnaire (undertaken as part of the research program) that seeks the opinions of system users on the effectiveness of their individual systems at processing and delivering acceptable colour separations.

description: The Casimir energy is evaluated for massless scalar fields under Dirichlet or Neumann boundary conditions, and for the electromagnetic field with perfect conductor boundary conditions on one and two infinite parallel plates moving by uniform proper acceleration through the Fulling--Rindler vacuum in an arbitrary number of spacetime dimension. For the geometry of a single plate the both regions of the right Rindler wedge, (i) on the right (RR region) and (ii) on the left (RL region) of the plate are considered. The zeta function technique is used, in combination with contour integral representations. The Casimir energies for separate RR and RL regions contain pole and finite contributions. For an infinitely thin plate taking RR and RL regions together, in odd spatial dimensions the pole parts cancel and the Casimir energy for the whole Rindler wedge is finite. In $d=3$ spatial dimensions the total Casimir energy for a single plate is negative for Dirichlet scalar and positive for Neumann scalar and the electromagnetic field. The total Casimir energy for two plates geometry is presented in the form of a sum of the Casimir energies for separate plates plus an additional interference term. The latter is negative for all values of the plates separation for both Dirichlet and Neumann scalars, and for the electromagnetic field.

description: The nwnber of maize farms declared bankrupt in South Afiica rose sharply from 16 farms in 1970 to 205 farms in 1986 and then fluctuated around the 150 farm level in the early l 990's. Ordinary least squares regression and principal component analysis confirmed a priori expectations that maize farm bankruptcy was negatively related to the lagged real maize producer price and annual rainfall (business risk factors), but positively related to the lagged aggregate farm debt/asset ratio and lagged real interest rates ( financial risk factors).

description: We consider a spin-1/2 charged particle in the plane under the influence of two idealized Aharonov-Bohm fluxes. We show that the Pauli operator as a differential operator is defined by appropriate boundary conditions at the two vortices. Further we explicitly construct a basis in the deficiency subspaces of the symmetric operator obtained by restricting the domain to functions with supports separated from the vortices. This construction makes it possible to apply the Krein's formula to the Pauli operator.

EXAMINING THE INFLUENCE OF PERCEIVED RACISM ON PRETERM BIRTH AMONGST A SAMPLE OF PREGNANT WOMEN IN BALTIMORE, MARYLAND
Creators: name: Davidson, Mary Elizabeth
Publisher: name: American University
Year: 2023

description: Racism is a grave problem in the United States. The individual and community characteristics that protect against racism are of interest in health inequity prevention research. African American (AA) women are 80% more likely to have a preterm birth (PTB) than mothers of other racial groups. Previous research reveals that racism has an adverse effect on pregnancy outcomes, including PTB. The current study aims to determine the relationship between African American women’s reports of lifetime experiences of perceived racism and the adverse birth outcome of PTB. A secondary data analysis was used to examine the relationship between perceived racism and PTB, using data collected from the Baltimore Preterm Birth Study cohort (n=845). The analysis includes the examination of demographic characteristics of the sample population and perceived racism prevalence using frequencies and proportions where appropriate. Structured interviews were conducted with pregnant women and medical records abstracted for pregnancy outcome. An index of Overall Racism and its two subindices (Group and Personal Racism) were created using items from the Racism and Lifetime Experience Scale (RaLES)-Brief questionnaire. Consistent with the high-risk study population, the PTB rate was approximately 17%. Women had a mean age of 23.2 years (SD 5.7), and nearly half (49%) had ≤ 12 years of education. Perceived racism was not associated with PTB. Previous preterm birth was associated with increased risk of PTB (X 2(2, N=845) =21.3, p <0.01). Traditional explanations, focusing on single risk factors, have not adequately explained racial disparities in PTB. More recent explanations have focused on understanding the health implications across the life-course. Although this study examines perceived racism and its relationship with individual and interpersonal relationships, further research is needed to determine the correlation between perceived racism and PTB and racisms' adverse impact on health equity for AA women and mothers.

description: Realisation of the tetragonal phase of $Cs_2CuCl_4$ is possible using specific crystal growth conditions at a temperature below $281K$. This work deals with the comparison of the magnetic susceptibility and the magnetization of this new tetragonal compound with the magnetic behaviour of tetragonal $Cs_2CuCl_{2.9}Br_{1.1}$, $Cs_2CuCl_{2.5}Br_{1.5}$, $Cs_2CuCl_{2.2}Br_{1.8}$ and presents consistent results for such quasi $2-D$ antiferromagnets. Structural investigation at low temperature for $Cs_2CuCl_{2.2}Br_{1.8}$ shows no phase transition. The structure remains in the tetragonal symmetry $I4/mmm$. Furthermore, several magnetic reflections corresponding to the propagation vector $k = (0, 0, 0)$ are observed for this tetragonal compound through neutron diffraction experiments below the magnetic phase transition at $T_N = 11.3K$ confirming its antiferromagnetic nature.

title: Metapopulation dynamics of Primula vulgaris
Creators: name: Valverde Valdés, María Teresa
Publisher: name: The Open University
Year: 1996

description: Primula vulgaris Huds. shows a patchy distribution within its forest habitat. Each patch is viewed as a local population within a metapopulation. Patches are associated with gaps in the canopy and the foundation and extinction of local populations are coupled with forest canopy dynamics. This study analyses the system formed by local populations and their forest environment with the aim of understanding the factors that affect P. vulgaris metapopulation dynamics. Data was collected on the demography of local populations in patches in different light conditions, and on the changes in the canopy brought about by the forest regeneration cycle. These were combined to model the effect of forest disturbance regime and seed dispersal on metapopulation dynamics and overall abundance of P. vulgaris in the forest.

The demography of local populations varied spatially in forest patches under different light conditions. Population growth rate (ƛ) was higher in brighter patches than in closed canopy patches. Population under closed canopy conditions may show negative growth rates which may result in eventual extinction.

The system of forest patches is a dynamic one: canopy gaps are constantly opening and closing. Canopy closure occurs at an exponential rate and the structure of the forest (i.e., proportion of patches with different light conditions) depends largely on the disturbance regime (i.e., rate of gap creation).

Simulation results showed that higher disturbance regimes produced higher metapopulation growth rate and higher overall P. vulgaris abundance in the forest. Long-distance seed dispersal reduced overall P. vulgaris abundance because it implied an amount of seed loss; however, it increased metapopulation growth rate, as it allowed the colonisation of newly-opened gaps. Under low disturbance regimes, P. vulgaris may form non-equilibrium metapopulations. Whether there is a balance between colonisations and extinctions depends on the effectiveness of seed dispersal in allowing the occupation of gaps.

description: We prove that any Cayley graph $G$ with degree $d$ polynomial growth does not satisfy $\{f(n)\}$-containment for any $f=o(n^{d-2})$. This settles the asymptotic behaviour of the firefighter problem on such graphs as it was known that $Cn^{d-2}$ firefighters are enough, answering and strengthening a conjecture of Develin and Hartke. We also prove that intermediate growth Cayley graphs do not satisfy polynomial containment, and give explicit lower bounds depending on the growth rate of the group. These bounds can be further improved when more geometric information is available, such as for Grigorchuk's group.

description: We consider a class of space-times given by a stationary extension of the Zipoy-Voorhees metric that was found by Halilsoy. We show that the solutions do not describe rotating sources but must be interpreted, similarly to the NUT case, as deformed sources endowed with a gravitomagnetic charge. We show that the Halilsoy family is directly linked to the NUT space-time, which can be obtained in the limit of vanishing deformations. We investigate the motion of test particles and photons in this class of space-times, in particular the innermost stable circular orbits and photon capture radius. Finally we show that this class of solutions possesses a sub-manifold where closed time-like curves are allowed.

description: We study a codimension 2 braneworld in the Einstein Gauss-Bonnet gravity. We carefully examine the structure of possible singularities in the system which characterize the braneworld through matching conditions. Consequently, we find that the thickness of the brane can be incorporated as the distributional source, which we dub quasi-thickness. On the basis of our formalism, we analyze the linearized gravity and show the conventional Einstein gravity can be recovered on the brane. In the nonlinear regime, however, we find corrections due to the thickness and the bulk geometry. We also point out a possibility that the thickness plays a role of the dark matter/energy in the universe.

description: Cumulative probability distributions (CPDs) of a few financial criteria were generated with the aid of the FARMS model and used to evaluate diversification as a method of risk management by Winterton farmers. Given the management abilities of the farmer, the efficiency of risk management is influenced by the composition of fam,ing enterprises, the interaction between the enterprises and the debt-burden situation. The use of CPDs serves to portray the uncertainty and nature of the outcome as well as the financial implications of the inclusion of altemative enterprises clearly. Since the decision maker is familiar with the total width of outcome of the financial criteria, the probability of a specific required outcome level being realised can be detem,ined. ln addition the model can be used to evaluate cash and credit flow interactively in the decision-making process. With the assistence of the model and the use of the method of approach different management strategies can be evaluated at farming level.

description: Fast scan cyclic voltammetry (FSCV) is an analytical technique that was first developed over 30 years ago. Since then, it has been extensively used to detect dopamine using carbon fiber microelectrodes (CFMEs). More recently, electrode modifications and waveform refinement have enabled the detection of a wider variety of neurochemicals including nucleosides such as adenosine and guanosine, neurotransmitter metabolites of dopamine, and neuropeptides such as enkephalin. These alterations have facilitated the selectivity of certain biomolecules over others to enhance the measurement of the analyte of interest while excluding interferants. In this thesis, we detail these modifications and how specializing CFME sensors allows neuro-analytical researchers to develop tools to understand the neurochemistry of the brain in disease states and provide groundwork for translational work in clinical settings. Multiplexing neurochemical measurements in multiple brain regions simultaneously have long been in demand in the greater neuroscience community. Metal microelectrode arrays have been vastly used for neural recordings but cannot measure biomolecules in the brain. Conversely, carbon fiber microelectrodes (CFMEs) have been known to measure neurotransmitters with FSCV due to their ability to adsorb cationic monoamine neurotransmitters on the surface through electrostatics or pi-pi stacking. Although FSCV in tandem with CFMEs have high temporal and spatial resolution, only a single channel potentiostat and electrodes have been utilized. In this work, we configured the carbon fiber multielectrode array (MEA), to a commercially available 4-channel potentiostat for multiplexing neurochemical measurements. The MEA’s relative performance was compared to single channel CFMEs. Dopamine detection was found to be adsorption controlled on the surface of the multielectrode array. Multiple waveforms were applied to each fiber of the multi array simultaneously to detect four different analytes on each electrode of the MEA. A proof of concept ex-vivo experiment showed that the MEA could record redox activity in the mouse caudate putamen and detect dopamine in a 3mm2 area. To our knowledge, this is the first use of the MEA paired with a commercial multichannel potentiostat for multi-waveform application and neurotransmitter codetection. This novel array may aide in future studies to better understand complex brain heterogeneity, the dynamic neurochemical environment, and how disease states or drugs affect separate areas concurrently.

description: Disc spectra from highly luminous black hole binaries are observed to be rather simple, despite theoretical predictions to the contrary. We collate the disc-dominated spectra from multiple observations of 10 separate sources, and show that these overwhelmingly follow a multi-temperature disc blackbody spectrum with luminosity proportional to T^4, and that such discs are stable. These results are in conflict with standard Shakura-Sunyaev alpha-discs predictions, including proposed modifications such as additional energy loss in a jet, wind or corona. Accretion disc spectra can be useful, reliable guides to the disc structure, and should be used to test the next generation of accretion disc models, in which the disc viscosity is calculated self-consistently from the magnetically generated turbulent dynamo.

 Remarks
 During a recent revision of Aprusia, Grismado et al. (2011) redescribed A. strenuus based on the original juvenile specimens. Although they mentioned the possibility that A. strenuus might be conspecific with one of the other described species, they could not unambiguously match any of their specimens to the original types or description of A. strenuus. We conducted extensive fieldwork in Nuwara Eliya and the surrounding forests. However, we did not find any Aprusia specimens in the area. Further, none of our specimens can be unambiguously matched to the original types or the recent redescription of Grismado et al. (2011) of the species. As we continue to search for A. strenuus, we refrain from effecting any taxonomic changes at this juncture.

description: This article examines the requirements for successful redistribution of land to emerging commercial farmers. It outlines a model used to successfully finance emerging commercial farmers in the sugar industry. The model uses a capital sacrifice by the seller to subsidise the interest rate on the bond on a declining, inflation linked basis, this overcomes the initial cash flow problems associated with agricultural land purchases. The article proposes this as a method which could finance other land transactions with very limited impact on the fiscus, land and capital markets.

description: The tangential layers are characterized by a bulk plasma velocity and a magnetic field that are perpendicular to the gradient direction. They have been extensively described in the frame of the Magneto-Hydro-Dynamic (MHD) theory. But the MHD theory does not look inside the transition region if the transition has a size of a few ion gyroradii. A series of kinetic tangential equilibria, valid for a collisionless plasma is presented. These equilibria are exact analytical solutions of the Maxwell-Vlasov equations. The particle distribution functions are sums of an infinite number of elementary functions parametrized by a vector potential. Examples of equilibria relevant to space plasmas are shown. A model for the deep and sharp density depletions observed in the auroral zone of the Earth is proposed. Tangential equilibria are also relevant for the study of planetary environments and of remote astrophysical plasmas.

In that case, the underlying numerical implementation is not affected by the coupling itself, but its functionality is carried over in the interface. This method is efficient for solving the equations of motion for a self-gravitating system over a wide range of scales. We adopt a dedicated integrator for solving each particular part of the problem and combine the results to a self-consistent solution. In particular, we explore the possibilities of combining the evolution of one or more microscopic systems that are embedded in a macroscopic system. The here presented generalizations of Bridge include higher-order coupling strategies (from the classic 2nd order up to 10th-order), but we also demonstrate how multiple bridges can be nested and how additional processes can be introduced at the bridge time-step to enrich the physics, for example by incorporating dissipative processes. Such augmentation allows for including additional processes in a classic Newtonian N-body integrator without alterations to the underlying code. These additional processes include for example the Yarkovsky effect, dynamical friction or relativistic dynamics. Some of these processes operate on all particles whereas others apply only to a subset. The presented method is non-intrusive in the sense that the underlying methods remain operational without changes to the code (apart from adding the get- and set-functions to enable the bridge operator). As a result, the fundamental integrators continue to operate with their internal time step and preserve their local optimizations and parallelism. ... abridged ...

description: The current literature on the provision of rural financial services places far more emphasis on the sustainability of rural financial institutions as a means of ensuring effective provision than has been the practice to date. This paper reviews the various measures that have been used to measure both the efficiency (defined as effectiveness and productivity) and the outreach of rural financial institutions, as two key areas that have to be attended to if institutional sustainability is to be achieved. The results of some preliminary investigations into rural financial institutions in South Africa are then reported.

description: There is individual variability in the degree to which people view stress as debilitating versus enhancing. These stress mindsets have been shown to moderate the link between stress and psychological, physiological, and performance outcomes. However, when people are asked about their stress mindset, they are asked to generally think about stress and how it might impact their health, performance, and well-being. There is a gap in the literature on whether stress mindsets vary for specific categories of stressors. In the present study, we recruited a sample of college students to complete the Stress Mindset Measure-General (SMM-G) and adapted the measure to address 6 different types of stressors in order to investigate whether (1) different stressor types are associated with different stress mindsets, and particularly whether (2) stigma-based stress is perceived as more debilitating in comparison to other categories of stress. Participants are also asked about the degree in which they thought about these 6 stressor categories upon completing the SMM-G. We found that when people complete the SMM-G, they tend to be thinking most about academic oriented events. We also found that stress mindset ratings vary for different categories of stressors, with academic and societal stressors being perceived as the most enhancing and financial and illness/injury related stressors as the least. Importantly, there were differences based on identity, such that those who identify as a racial/ethnic, sexual, and/or gender minority were more likely to consider identity-based stressors in their stress mindset ratings and were more likely to consider identity-based stressors as more debilitating.

description: The purpose of this paper is to discuss development and use of procedures to e_valuate application of ~ovine Somat~tro~in (BST) with respect to profitability at farm level. BST remains a controversial product and uncertamty surroundmg its appropriateness as teclmology is increased by the fact that no Joe~) study in conn~ction with its profitability ~as been conducted previously. On-farm response trials at three representative case study sites and a personal t~lepho~uc survey conducted amongst existing users of BST provided a valuable basis to develop and apply a management s1mulahon model. The model and procedures of analysis are flexible and could be applied to other problems of dairy farm manageme_n~. Results indicated that, given the conditions of research, utilisation ofBST proved to be profitable. BST has the capab1hty to improve profitability of certain dairy businesses. The critical factors in determining profitability of ~ST utilisation, apart from management, are the milk price, response to BST as we11 as BST and feed cost. Milk production quotas may have a negative effect on profitability ofBST.

description: Different methods are used to determine the scaling exponents associated with a time series describing a complex dynamical process, such as those observed in geophysical systems. Many of these methods are based on the numerical evaluation of the variance of a diffusion process whose step increments are generated by the data. An alternative method focuses on the direct evaluation of the scaling coefficient of the Shannon entropy of the same diffusion distribution. The combined use of these methods can efficiently distinguish between fractal Gaussian and Lévy-walk time series and help to discern between alternative underling complex dynamics.

description: We explore the relationship between symmetrisation and entanglement through measurements on few-particle systems in a multi-well potential. In particular, considering two or three trapped atoms, we measure and distinguish correlations arising from two different physical origins: antisymmetrisation of the fermionic wavefunction and interaction between particles. We quantify this through the entanglement negativity of states, and the introduction of an antisymmetric negativity, which allows us to understand the role that symmetrisation plays in the measured entanglement properties. We apply this concept both to pure theoretical states and to experimentally reconstructed density matrices of two or three mobile particles in an array of optical tweezers.

description: Le texte évalue les conséquences du changement de la réglementation française de 2001en ce qui concerne le cumul des mandats, qui a limité la possibilité de tenir simultanément plusieurs mandats électifs. La comparaison avant et après la mise en œuvre de la nouvelle loi permet de conclure que (i) les candidats aux élections législatives se sont adaptés aux nouvelles règles en réduisant les mandats locaux détenus; (ii) les candidats ont également montré une tendance à changer la nature des mandats exercés. Ces résultats mettent en lumière les modalités d'application de la loi qui lui donneront toute son efficacité.
description: The paper assesses the consequences of the 2021 change in French regulation regarding the multi-holding mandates, which restricted the opportunity to simultaneously hold several elective mandates. Comparing before and after the implementation of the new Law, empirical descriptions show that (i) candidates in legislative elections adapted to the new rules by reducing the local mandates held; (ii) candidates also showed a tendency to change the nature of the mandates held. These results can give some insight into the future consequences of the law just passed in 2014.

description: Many development economists have regarded intercropping as a traditional way of ~owing. crops, w~ch to them cannot stand up to present day realities. The results in this paper and other research results ~!ve a d1f!erent picture. It shows ~at intercropping has a higher total productivity per urut land area and ~eater stab1hty of yields and revenues than its monocropping counterparts. It could therefore be seen as a system which could be used to fill the gap created by the problem of scarcity of land as well as using it to improve household food insecurity.
