Evaluation of hemoglobin AIc as a measure of diabetic control
Creators: name: Thompson, Katherine Hirsch
Publisher: name: University of British Columbia

description: Diabetic individuals have been found to have consistently higher levels of a minor hemoglobin component, HbAIc, than non-diabetic individuals. Previous investigators have suggested that variation in these high levels of HbAIc may be a reflection of the degree of diabetic hyperglycemia, of hypertriglyceridemia in diabetes, and of diabetic control. To date, evaluation of HbAIc as a clinically useful parameter has been hampered by the complexity of the method of measurement, the inconsistency in ranges of normal values reported, and the lack of a broad data base for comparison with new results. This investigation began with a critical appraisal of the methods currently in use for measurement of HbAIc, followed by a simplification and standardization of theJ assay. Then the levels of HbAIc in 16 non-diabetics and 47 diabetics were determined and the mean values for these 2 groups compared. The relationships between HbAIc levels in the diabetics and selected clinical data |fasting blood sugar, 24-hour urinary sugar, age,duration of illness, dietary record, insulin dosage, and family history of diabetes) were examined. Finally, the degree of diabetic control in each of the diabetic patients was estimated by the attending physician on a scale of 1 to 5 (1=very good, 2=good, 3=fair, 4=poor, 5=very poor) and was compared with the HbAIc measurement. Results of the investigation have shown that the chromatographic measurement of HbAIc is unusually sensitive to the pH of developers used and also somewhat variable with respect to the length of storage time and the optical density at which samples are read. The comparison of mean values of HbAIc for diabetics and non-diabetics has confirmed the approximately twofold higher concentration of HbAIc in diabetics. Significant correlations were found between HbAIc and fasting blood sugar (r = .442), fat content of diet (r=-. 300) , family history of diabetes (r=-.312) and degree of diabetic control (r=.529). Thus, HbAIc values tend to be higher in patients whose fasting blood sugar is high, whose diet contains relatively little fat, whose relatives are diabetic and /or whose diabetic control is poor. Correlations between HbAIc and duration of diabetes, HbAIc and insulin dosage or HbAIc and 24-hour urinary sugar were not statistically significant (r=-.131, r=-.264, r=„067, respectively). The HbAIc level appears to be an accurate reflection of fasting blood sugar levels averaged over a prolonged period of time (r=.587). In conclusion, HbAIc levels were found to provide an objective measure of diabetic control. The improved assay method makes it a practical and valuable tool for the clinician as well as the investigator. Measurement of HbAIc levels in diabetics presents a considerable advantage over currently available measures of diabetic control in assessing the long-term effectiveness of diabetic management.

description: For two families of four-dimensional off-shell N = 2 supersymmetric nonlinear sigma-models constructed originally in projective superspace, we develop their formulation in terms of N = 1 chiral superfields. Specifically, these theories are: (i) sigma-models on cotangent bundles T*M of arbitrary real analytic Kaehler manifolds M; (ii) general superconformal sigma-models described by weight-one polar supermultiplets. Using superspace techniques, we obtain a universal expression for the holomorphic symplectic two-form ω^{(2,0)} which determines the second supersymmetry transformation and is associated with the two complex structures of the hyperkaehler space T*M that are complimentary to the one induced from M. This two-form is shown to coincide with the canonical holomorphic symplectic structure. In the case (ii), we demonstrate that ω^{(2,0)} and the homothetic conformal Killing vector determine the explicit form of the superconformal transformations. At the heart of our construction is the duality (generalized Legendre transform) between off-shell N = 2 supersymmetric nonlinear sigma-models and their on-shell N = 1 chiral realizations. We finally present the most general N = 2 superconformal nonlinear sigma-model formulated in terms of N = 1 chiral superfields. The approach developed can naturally be generalized in order to describe 5D and 6D superconformal nonlinear sigma-models in 4D N = 1 superspace.

description: We aim to better understand how the spatial structure of molecular clouds is governed by turbulence. For that, we study the large-scale spatial distribution of low density molecular gas and search for characteristic length scales. We employ a 35 square degrees 13CO 1-0 molecular line survey of Cygnus X and visual extinction (A_V) maps of 17 Galactic clouds to analyse the spatial structure using the Delta-variance method. This sample contains a large variety of different molecular cloud types with different star forming activity. The Delta-variance spectra obtained from the A_V maps show differences between low-mass star-forming (SF) clouds and massive giant molecular clouds (GMC) in terms of shape of the spectrum and its power-law exponent beta. Low-mass SF clouds have a double-peak structure with characteristic size scales around 1 pc (though with a large scatter around this value) and 4 pc. GMCs show no characteristic scale in the A_V-maps, which can partly be ascribed to a distance effect due to a larger line-of-sight (LOS) confusion. The Delta-variance for Cygnus, determined from the 13CO survey, shows characteristic scales at 4 pc and 40 pc, either reflecting the filament structure and large-scale turbulence forcing or - for the 4 pc scale - the scale below which the 13CO 1-0 line becomes optically thick. Though there are different processes that can introduce characteristic scales, i.e. geometry, decaying turbulence the transition scale from supersonic to subsonic turbulence (the sonic scale), line-of-sight effects and energy injection due to expanding supernova shells, outflows, HII-regions, and the relative contribution of these effects strongly varies from cloud to cloud, it is remarkable that the resulting turbulent structure of molecular clouds shows similar characteristics.

description: Shot noise, originating from the discrete nature of electric charge, is generated by scattering processes. Shot-noise measurements have revealed microscopic charge dynamics in various quantum transport phenomena. In particular, beyond the single-particle picture, such measurements have proved to be powerful ways to investigate electron correlation in quantum liquids. Here, we review the recent progress of shot-noise measurements in mesoscopic physics. This review summarizes the basics of shot-noise theory based on the Landauer-Büttiker formalism, measurement techniques used in previous studies, and several recent experiments demonstrating electron scattering processes. We then discuss three different kinds of quantum liquids, namely those formed by, respectively, the Kondo effect, the fractional quantum Hall effect, and superconductivity. Finally, we discuss current noise within the framework of nonequilibrium statistical physics and review related experiments. We hope that this review will convey the significance of shot-noise measurements to a broad range of researchers in condensed matter physics.

description: The Qinghai-Tibetan Plateau (QTP), the source and upper reaches of many Asian rivers, are crisscrossed by rivers and dotted with lakes. Schizothoracinae fishes, species native to the QTP, are distributed widely through these rivers and lakes. Over the past decades, ecological protection has become increasingly intense. The rapid acquisition of the genetic information and accurate gene sequence database are assumed to play an important role in the conservation of species diversity and biodiversity. In this study, 153 COI sequences (648bp in length) covering 13 species in 8 genera of Schizothoracinae fishes in Qinghai Province were used to determine whether barcode could identify Schizothoracinae species accurately. The average Kimura two parameter (K2P) genetic distances within and among species were 0.35% and 8.83%, respectively. The maximum K2P distance within species was observed in Gymnocypris eckloni (1.36%) while minimum K2P distance among species was observed between Chuanchia labiosa and Schizopygopsis pylzovi (0.23%). Overlaps existed in K2P distance intra- and inter- species based on both the genes. Eleven groups with 9 single-species groups and 2 multi-species groups were identified through Automatic Barcode Gap Discovery System, which were consistent with the overlaps of K2P distance. 96.7% as the accurate ratio for COI barcode was calculated and high solution was observed in the phylogenetic trees based on COI gene and Cyt b gene. Except for the similar results based on two genes above, COI barcode was more economical than Cyt b gene. The SOM model successfully predicted characteristic-diagnostic sites at species level: 36 characteristic-diagnostic sites from eight species, in which 12 from Gmnodiptychus pachycgeilus, 2 from Platypharodon extremus, 7 from Ptychobarbus kaznakovi, 2 from Schizopygopsis anteroventris, 2 from Schizopygopsis malacanthus, 3 from Schizopygopsis malacanthus chengi, 3 from Schizothorax dolichonema and 5 from Schizothorax lantsangensis. Our results show that Schizothoracinae fishes can be identified validly by using COI DNA barcode. Thirty-six characteristic-diagnostic sites were proposed to be applied into works of species identification for the Schizothoracinae fishes in Qinghai Province.

The function of the anal papillae of saline-water mosquito larvae
Creators: name: Scherer, Nancy Mae
Publisher: name: University of British Columbia
Year: 2010

description: The role of the anal papillae of saline-water mosquito larvae is uncertain. Sodium ion and Cl¯ uptake by the papillae of larvae in dilute media has been demonstrated (Phillips and Meredith, 1969a). Indirect ultrastructural and physiological evidence suggests that these organs might also be active in ion transport under saline conditions (Phillips and r Meredith, 1969a; Meredith and Phillips 1973a, b; Bradley and Phillips, 1975; Phillips and Bradley, 1977; Phil 1 ips et al., 1 977) . Two possible functions of the anal papillae in saline media have been suggested: (1) that the papillae excrete Na+ and Cl⁻, and (2) that the papillae take up ions present in low concentration in saline waters. Uptake of K⁺ by the anal papillae was measured for the investigation of the second hypothesis. Completion of this study involved measuring the total K⁺ balance of the larvae. These hypotheses were tested by measuring hemolymph osmolarity and ion concentrations of normal and papillaeless larvae in a range of salinities, measuring ⁴²K influx, total body K⁺ content, and the electro-potential difference across the papillae. The anal papilae of the saline mosquito larva, Aedes taeniorhynchus, living in saline waters did not actively take up K+. Indirect evidence indicated that the anal papillae were also not involved in Na+ or Cl⁻ secretion in concentrated media. When A. taeniorhynchus larvae were reared in distilled water, the anal papillae were responsible for nearly all the K⁺ uptake, as is the case for strictly freshwater species of mosquito larvae. The observed influx of K⁺ across the papillae of 46 nmol cm⁻² h⁻¹ occurred against both chemical and electrical potential gradients, indicating that transport is active. Potassium uptake by the anal papillae was also observed in the saline mosquito larva, Aedes campes tri s, from both dilute (about 10 m0sm) and concentrated (about 300 m0sm) solutions although uptake was much reduced in the latter. Uptake was increased by acclimation of the larvae to dilute media. Potassium influx occurred against the concentration gradient but along the electrical p o -. tential gradient. Uptake followed Michaelis-Menten kinetics with an approximate K0.5 of 3.2 mM and Vmax of 1.1 nmo1 mg⁻¹ h⁻¹.

description: I model profiles of the [NeII] forbidden emission line at 12.81um, emitted by photoevaporative winds from discs around young, solar-mass stars. The predicted line luminosities (~ 1E-6 Lsun) are consistent with recent data, and the line profiles vary significantly with disc inclination. Edge-on discs show broad (30-40km/s) double-peaked profiles, due to the rotation of the disc, while in face-on discs the structure of the wind results in a narrower line (~10km/s) and a significant blue-shift (5-10km/s). These results suggest that observations of [NeII] line profiles can provide a direct test of models of protoplanetary disc photoevaporation.

title: Austin Osman Spare: the artist's books (1905-1927)
Creators: name: Wallace, William
Publisher: name: University of Kent
Year: 2021

description: This thesis constitutes a complete analysis of the following five books: Earth: Inferno (1950), A Book of Satyrs (1907 and 1909), The Book of Pleasure (1913), The Focus of Life (1921), and The Anathema of Zos (1927). Emphasis is placed throughout upon the interpretation of the drawings within the context of the accompanying text. All allegorical nomenclature has been interpreted and putative identification given to all significant characters and their functions. The basic thesis is that the books constitute an interconnected developmental sequence; that the artist pursues and refines certain major themes and exhaustively explores allegorical method. In addition thta this leads to the evolution of a method of symbolic automatism. This is presented as the praxis of the evolving cosmology, mysticism and world-view developing directly from Earth: Inferno. The argument is that Earth: Inferno and A Book of Satyrs establish Spare's method of synthesizing influences such as Dante and Blake to evolve effective pictorial and textual tropes. The Book of Pleasure is interpreted as part allegory within the major drawings, and part automatism with symbolic adjuncts in others. All symbolism is interpreted and given putative identification and its function as praxis fully discussed in relation to magical and creative method. The fourth and fifth books are affirmed as mature articulations of Spare's mysticism and magical theory, textually expressed in more emotive persuasive narrative forms through protagonists originating in name and function in Earth: Inferno. The illustrations of The Focus of Life are identified as thematic developments of major concerns of The Book of Pleasure with evidence of considerable influence of Goethe's Faust. Earth: Inferno is considered as the initiation of Spare's method of incorporating both revealed and concealed thematic aspects both textually and pictorially, as well as his prevailing syncretistic approach. Diverse components from Dante, Blake, the Kabbalah, Blavatsky and Egypt are identified. It is argued that Dante and Blake are cast in Kabbalist roles through contemporary scholarship; with Blavatsky as a precedent for synthesis and fusion of seemingly diverse concepts. A Book of Satyrs is construed as complex textual pictorial work functioning on four Dantean levels: Satirical, Biblical / Christian, Kabbalist and Greek Tragic. The Book of Pleasure is present as part allegorical but mainly a didactic work concerned with Spare's symbolic automatism. The Focus of Life is defined as maintaining the Faust theme, whilst the two images of The Anathema of Zos are briefly examined; one in relation to occult influences discussed as influential upon A Book of Satyrs.
Biomedicine and pain

description: The focus of my research is on contemporary biomedical construction of pain as an object, i.e. the different ways in which pain has been conceptualized and approached as a specific site of investigation in biomedicine. 

A significant shift in the scientific conception of pain occured in the second half of XXth century. In 1965, Ronald Melzack and Patrick D. Wall propose the Gate Control theory of pain mechanism. This theory denies a fixed and direct relationship between stimulus and pain perception, and emphazises the role played by psychological factors in pain. The IASP utilizes this perspective on the phenomenon, describing pain as “an unpleasant sensory and emotional experience associated to an actual or potential tissue damage or described in the terms of such a damage.” 

The relationship between pain and damage is pivotal in the definition of pain as a pathological entity. In particular, the biomedical approach to pain appears to be strongly characterized by a dualistic view of its aetiology. Disease conceptions such as “psychogenic pain” and chronic pain are deeply influenced by the ways in which psychological factors have been interpreted as components, or as causes of pain.
 
In the second part of my dissertation, I focus on fibromyalgia, which is emblematic of the problematic acknowledgment of chronic pain as a disease. Even if fibromyalgia is actually treated in Rheumatology, its status as a disease is blurred, mainly because of its complex symptomatology including both physiological manifestations and psychological ones. 

In the conclusion, I present a scenario of the different ways in which this disease is dealt with in biomedical knowledge, through  medical literature, clinical practice, and patients’ accounts. The findings of an ethnographic enquiry in the Rheumatology Division of a local clinic and a visual research on patients’ experiences are analyzed and discussed.

description: We present the two- and three-point real space correlation functions of the five-year WMAP sky maps, and compare the observed functions to simulated LCDM concordance model ensembles. In agreement with previously published results, we find that the temperature correlation functions are consistent with expectations. However, the pure polarization correlation functions are acceptable only for the 33GHz band map; the 41, 61, and 94 GHz band correlation functions all exhibit significant large-scale excess structures. Further, these excess structures very closely match the correlation functions of the two (synchrotron and dust) foreground templates used to correct the WMAP data for galactic contamination, with a cross-correlation statistically significant at the 2sigma-3sigma confidence level. The correlation is slightly stronger with respect to the thermal dust template than with the synchrotron template.

description: We report here a general theory describing photoelectron transportation dynamics in GaAs semiconductor photocathodes. Gradient doping is incorporated in the model through the inclusion of directional carrier drift. The time-evolution of electron concentration in the active layer upon the injection of an excitation pulse is solved both numerically and analytically. The predictions of the model are compared with experiments via carrier-induced transient reflectivity change, which is measured for gradient-doped and uniform-doped photocathodes using femtosecond pump-probe reflectometry. Excellent agreement is found between the experiments and the theory, leading to the characterization of key device parameters such as diffusion constant and electron decay rates. Comparisons are also made between uniform doping and gradient doping for their characteristics in photoelectron transportation. Doping gradient is found to be able to accelerate electron accumulation on the device surface. These results offer new insights into the dynamics of III-V photocathodes and potentially open a new avenue toward experimental characterization of device parameters.

При моделировании использованы физические параметры, характерные для типичного газогидратного пласта. Время нагрева резервуара составляло 10 суток. В результате исследования модели получены пространственные и временные распределения температуры, давления, гидрато-, водо- и газонасыщенности в пласте. Произведен расчет массы газа, выделившегося при диссоциации газогидрата. Выполнена оценка энергоэффективности электромагнитного нагрева. Результаты вполне применимы на практике, а метод электромагнитного нагрева технически достижим и конкурентоспособен.
description: Numerical studies are performed with the two-dimensional axisymmetric model of gas hydrate decomposition in porous media under the action of microwave heating. The system of equations describing the above process includes the mass balance equations of gas, water and hydrate phases, the energy balance equation, generalized Darcy’s law for water and gas, and the Kim – Bishnoi kinetics equation for hydrate decomposition reaction. The system of equations resolves itself into four differential equations relative to temperature, pressure, volume hydrate, water, and gas saturation with appropriate boundary and initial conditions. Simulation of gas hydrate decomposition in porous media under the action of microwave heating is carried out by finite element method. Physical parameters characteristic of a typical hydrate reservoir are used in the modeling. The reservoir was heated for ten days. Spatial and temporal distribution of temperature, pressure, hydrate, water, and gas saturation were obtained. The mass of gas evolved during hydrate dissociation was determined. The calculation of the energy efficiency of electromagnetic heating was carried out. These results are quite usable from a practical standpoint, and the electromagnetic heating method is technically achievable and competitive.

description: The development of a multibody model of a motorbike engine cranktrain is presented in this work, with an emphasis on flexible component model reduction.
A modelling methodology based upon the adoption of non-ideal joints at interface locations, and the inclusion of component flexibility, is developed: both are necessary tasks if one wants to capture dynamic effects which arise in lightweight, high-speed applications.
With regard to the first topic, both a ball bearing model and a journal bearing model are implemented, in order to properly capture the dynamic effects of the main connections in the system: angular contact ball bearings are modelled according to a five-DOF nonlinear scheme in order to grasp the crankshaft main bearings behaviour, while an impedance-based hydrodynamic bearing model is implemented providing an enhanced operation prediction at the conrod big end locations.
Concerning the second matter, flexible models of the crankshaft and the connecting rod are produced. The well-established Craig-Bampton reduction technique is adopted as a general framework to obtain reduced model representations which are suitable for the subsequent multibody analyses. A particular component mode selection procedure is implemented, based on the concept of Effective Interface Mass, allowing an assessment of the accuracy of the reduced models prior to the nonlinear simulation phase. In addition, a procedure to alleviate the effects of modal truncation, based on the Modal Truncation Augmentation approach, is developed. In order to assess the performances of the proposed modal reduction schemes, numerical tests are performed onto the crankshaft and the conrod models in both frequency and modal domains. 
A multibody model of the cranktrain is eventually assembled and simulated using a commercial software. Numerical results are presented, demonstrating the effectiveness of the implemented flexible model reduction techniques. The advantages over the conventional frequency-based truncation approach are discussed.

description: We report neutron diffuse scattering measurements on a single crystal of 68%Pb(Mg1/3Nb2/3)O3-32%PbTiO3. Strong diffuse scattering is observed at low temperatures. An external field applied along the [001] direction affects the diffuse scattering in the (HK0) plane significantly, suggesting a redistribution occurs between polar nanoregions of different polarizations perpendicular to the field. By contrast, the [001] field has no effect on the diffuse scattering in the (HOL) and (0KL) zones.

description: Peak-bagging and peak-tagging of asteroseismic modes, which involve their detection, indentification and characterization, are crucial for all downstream inferences of stellar properties. Filtering techniques, such as curvelet analysis has been shown to improve signal-to-noise ratio leading to better peak-tagging [1]. In recent times, deep learning techniques have outperformed traditional algorithmic denoising techniques for image denoising for a variety of noise profiles. In this study we explore the applicability of different machine learning frameworks for denoising asteroseismic spectra.

description: To obtain an accurate description of broad-band photometric star cluster evolution, certain effects should be accounted for, such as the preferential loss of low-mass stars and the retain of stellar remnants. Moreover, the IMF and metallicity affect photometry as well. Due to their advanced evolutionary state, globular clusters (GCs) are interesting test cases for cluster models describing these effects. In this paper we describe cluster models in which the above effects are included. The photometric evolution of clusters is predicted, and the results are applied to Galactic GCs. The presented cluster models represent an analytical description of the evolution of the underlying stellar mass function due to stellar evolution and dynamical cluster dissolution. Stellar remnants are included by using initial-remnant mass relations, while cluster photometry is computed from the Padova 1999 isochrones. Our study shows that the preferential loss of low-mass stars, the retain of stellar remnants, as well as IMF and metallicity variations strongly influence the magnitude, colour and mass-to-light ratio evolution of clusters. The different effects can be clearly separated with our models. The models are applied to the Galactic GC population, of which the magnitude, colour and mass-to-light ratio ranges are well reproduced. We also show that the mass-to-light ratios of clusters of similar ages and metallicities cannot be assumed to be constant for all cluster luminosities. Instead, mass-to-light ratio increases with cluster luminosity and mass. These models underline the importance of detailed cluster models when considering cluster photometry. With the analytic framework provided in this paper, observed cluster properties can be interpreted in a more complete perspective. (Abridged)

description: Chimera states, i.e., dynamical states composed of coexisting synchronous and asynchronous oscillations, have been reported to exist in diverse topologies of oscillators in simulations and experiments. Two-population networks with distinct intra - and inter-population coupling have served as simple model systems for chimera states since they possess an invariant synchronized manifold, in contrast to networks on a spatial structure. Here, we study dynamical and spectral properties of finite-sized chimeras on two-population networks. First, we elucidate how the Kuramoto order parameter of the finite sized globally coupled two-population network of phase oscillators is connected to that of the continuum limit. These findings suggest that it is suitable to classify the chimera states according to their order parameter dynamics, and therefore we define Poisson and Non-Poisson chimera states. We then perform a Lyapunov analysis of these two types of chimera states which yields insight into the full stability properties of the chimera trajectories as well as of collective modes. In particular, our analysis also confirms that Poisson chimeras are neutrally stable. We then introduce two types of "perturbation" that act as small heterogeneities and render Poisson chimeras attracting: A topological variation via the simplest nonlocal intra-population coupling that keeps the network symmetries, and the allowance of amplitude variations in the globally coupled two-population network, i.e., we replace the phase oscillators by Stuart-Landau oscillators. The Lyapunov spectral properties of chimera states in the two modified networks are investigated, exploiting an ansatz based on the network symmetry-induced cluster pattern dynamics of the finite size network.

The population dynamics of the aphids, macrosiphum avenae, metopolophium dirhodum, and rhopalosiphum padi on oats, Avena sativa CV Fraser
Creators: name: Woodgate, Rossalynn C.

description: Fraser oats were used to study populations of cereal aphids in 1972,1973 and 1974. The most commonly found species were Macrosiphum avenae (F.) (the English grain aphid), Metopolophium dirhodum (Wlk.) (Rose-grain aphid) and Rhopalosiphum padi (L.) (Oat bird-cherry aphid). Aphid density was highest in 1972, lower in 1973 and lowest in 1974. Generally M. avenae had the highest population with M. dirhodum slightly lower. Rhopalosiphum padi was found infrequently with low numbers. Fecundity trials, used to examine whether the difference between numbers of species was because of a difference in fecundity, did not substantiate field results but instead indicated that R.padi should have produced the highest population. Differences were not found in the population dynamics when the oats were planted in solid blocks instead of rows. A one month delay in the planting date did not change the total aphid population but did result ira higher proportion of M. avenae than found in any other plot. Coccinellid numbers in two out of the three years were considered negligible. In 1972 rain was thought to destroy many coccinellid before they reached large enough numbers to greatly affect the aphid population. No direct samples were taken of hymenopterous parasites but any found were collected and identified. Water experiments were conducted to study the effect of water on the fecundity of R. padi. It. was concluded - that R. padi definitely preferred wet conditions. Temperature and rainfall readings were used to show the effect of weather on aphid numbers. Weather was shown to be a major regulatory factor in the population dynamics of cereal aphids. Considerations were made for aphid mortality caused by sparrows.

title: The financing of economic growth and development: the case of Mexico
Creators: name: Warman, Fanny
Publisher: name: University of Kent
Year: 2021

description: This thesis examines general and specific aspects of the financing of the Mexican economy during the 1960-1990 period from both internal and external sources. The thesis focuses on two fundamental questions, the first of which is the analysis of the interrelationship between financial variables and real variables of the economy in order to assess the scope of the financial liberalisation policy being currently implemented in Mexico. Secondly, the thesis examines the impact of foreign capital flows on the domestic economy and the extent to which the expansion of the economy is constrained by the balance of payments. Following a general description of the Mexican economy presented in chapter one, which focuses on the evolution of financial variables and the financial policy implemented during the 1960-1990 period, chapter two analyses the theory of financial liberalisation, the hypothesis of which are tested for Mexico in chapters three and four. Chapter three examines the effects of financial variables, especially of real interest rates, on the level of total savings, financial savings, the level of investment, and economic growth. Chapter four takes into consideration the hypothesis that the allocation of resources through market forces under a liberalised financial system improves the productivity of investment. For this purpose, the chapter analyses the role of the financial sector under a liberalised environment and then attempts to measure the productivity of both private and public investment and examines the relationship between them. The theoretical and empirical effects of foreign capital inflows on domestic savings, investment and economic growth are examined in chapter five; in this context, the chapter develops a model in which both the effects of inflows and outflows of foreign capital are considered in order to estimate the net effect of foreign borrowing on economic growth. Finally, chapter six finds that the long-run rate of growth of the Mexican economy is closely approximated by the balance of payments equilibrium growth rate. Conclusions to be drawn from this thesis are presented in chapter seven.

title: Imaging the homeland: representations of Palestine in Palestinian art and popular culture
Creators: name: Sherwell, Tina
Publisher: name: University of Kent
Year: 2003

description: The thesis examines the construction of Palestinian national identity via a study of the representation of the homeland. The thesis focuses specifically on the representations created by Palestinians of the West Bank, Gaza Strip and Jerusalem. This Palestinian community, who continue to live on the land that was formerly Palestine, have created representations in the absence of their own official state apparatus and in the context in which representations of Palestinian identity met with harsh reprisals by the occupying authorities. This thesis contributes towards the study of national identity, for it reveals that nationalism is not an object in itself to be studied but is the outcome of the practices of social actors. The thesis explores the representation of the Palestinian homeland created by those who have experienced the land as the landscape of their every day lives under occupation, yet at the same time perceive the land as the future site of a Palestinian national homeland. It is the representations of these Palestinians who have experienced this paradox which is the focus of this thesis. In examining the representations of Palestinian national identity the thesis addresses the transformations the representation of the landscape has undergone as part of its incorporation into the national discourse. It specifically looks at the representation of the village and the peasantry as way towards understanding how Palestinians use elements of the past and from the landscape to image their national identity and the nation's past and future. Feelings of belonging and love for the homeland are explored in relation to the gendering of the homeland. While the final chapter examines what happens to the representation of the homeland, national identity and the role of art after a decline of a nationalist imperative and a period of heightened nationalism.
