Joby, Christopher Richard. "Calvinism and the arts : a re-assessment." Thesis, Durham University, 2005. http://etheses.dur.ac.uk/2873/.
Full textAbstract:
Although many believe John Calvin had a negative attitude towards the arts, particularly visual art, my contention is that we find within his writings and the development of the Reformed tradition a more positive attitude, to the arts than has hitherto been recognized. In chapters one and two, I look in detail at Calvin's own writings. I begin by examining exactly what type of visual art he rejected and what type he affirmed. I then look at how his eschatology and epistemology, particularly his use of the metaphor of mirror, allow us to argue for the placing of certain types of art within Reformed churches, notably history and landscape paintings. In chapters three and four, I consider music and architecture within Calvin's writings and the Reformed tradition. I suggest that the respective ontologies of metrical psalms and Reformed church-buildings both share something with those of history and landscape paintings and that it is inconsistent to allow for the former, but reject the latter. In the last three chapters, I focus on visual art. I examine the development of decoration and forms of visual art such as stained-glass windows in selected Reformed churches and suggest that it naturally follows that history and landscape paintings should be allowed for in such churches. I look at examples of these from seventeenth- century Netherlands, when Calvinism was the pre-dominant mode of religious expression, and argue that their form and content provide us with ontological and epistemological arguments which inevitably lead to the conclusion that their continued exclusion from Reformed churches is no longer tenable. In short, the use of appropriate works of art in Reformed churches is wholly consistent with the fundamental notions underpinning Calvin's theology and liturgical practices in the Reformed tradition, and their continued exclusion from most of these churches is an anomaly.

Full textAbstract:
Who were the Wydeviles? The family arrived with the Conqueror in 1066. As followers in the Conqueror’s army the Wydeviles rose through service with the Mowbray family. If we accept the definition given by Crouch and Turner for a brief period of time the Wydeviles qualified as barons in the twelfth century. This position was not maintained. By the thirteenth century the family had split into two distinct branches. The senior line settled in Yorkshire while the junior branch settled in Northamptonshire. The junior branch of the family gradually rose to prominence in the county through service as escheator, sheriff and knight of the shire. These roles enabled them to meet and work with men who had influence at court. The Wydevile that gave the family their entrée into royal service was Richard (ii), appointed steward to King Edward III’s daughter Isabella and then as steward at the king’s castle of Moor End. His son John (iii) maintained a similar pattern of service within the county and managed to negotiate the difficult years of Richard II’s reign and the usurpation of Henry IV without diminishing the family standing within the county. It was his sons who were to work closely with the royal family. Thomas and Richard (iii) served the Lancastrian royal princes loyally. Richard (iii)’s position led to a knighthood for his son Richard, so that by 1426 the family were at the highest level of the gentry, just below the aristocracy. Accused of being an ignoble family their status is traced from 1066 to the early fifteenth century. In 1448 Sir Richard Wydevile brought the family into the ranks of the nobility through an advantageous marriage. His secret marriage to Jacquetta of Luxembourg, widow of the duke of Bedford made him a member of the royal family, albeit a minor member. This connection led to his creation as lord Rivers in 1448. Rivers continued the family tradition of loyal service to the crown. His service in France and in England enabled him to find suitable marriages for three of his children by 1460/61 into baronial families. Like his great-grandfather Richard (ii), he managed to negotiate a change in king, moving smoothly from service to the Lancastrians to service with the Yorkists under Edward IV. In 1464 his daughter Elizabeth secretly married King Edward IV. It was this second secret marriage that led to the assault on the Wydeviles’ reputation and questioned their status. The political instability of the period required scapegoats each time a king was overthrown. The propaganda this generated is traced to establish if there is any truth in the charges of greed and covetousness made against the Wydeviles.

Thesis (MEng)--Stellenbosch University, 2015.ENGLISH ABSTRACT: Over the last few decades, wave run up prediction has gained the interest of numerous researchers and every newly-published paper has aimed to predict wave run up with greater accuracy. Wave run up is defined as the vertical elevation reached by a wave's, front water edge as it runs up a beach, measured relative to the still water line. Wave run up is dependent on the incidental wave height, the wave period, the beach slope and the wave steepness. The majority of publications incorporate all of these factors, but some do not, which has led to numerous debates. The goal of this study is to do a re-assessment of previously published wave run up formulae, to obtain a more informed understanding about wave run up and the available predictive empirical formulae. The study also seeks to evaluate the Mather, Stretch & Garland (2011) formula. The method for undertaking this objective comprised a physical model test series with 10 regular wave conditions on a constant slope, being 1/24, performed with an impermeable floor. Also, a beach study in the field was done on Long Beach, Noordhoek, where run up measurements were taken for 30 minute intervals, resulting in five test conditions. A numerical model was employed in conjunction with the beach study to determine the local offshore wave parameters transformed from a deep water wave rider. This information was used to correlate the run up measurements with known wave parameters. Firstly, the physical model assessment was performed to provide a proper foundation for run up understanding. Plotting empirical normalised run up values (R2/H0 ) versus the Iribarren number for different formulae, a grouping was achieved with upper and lower boundaries. The physical model results plotted on the lower end of this grouping, resulted in prediction differences of more than 10%. These differences may have been caused by the unevenness of the physical model slope or the fact that only one slope had been tested. Despite this, the results fell within a band of wave run up formulae located on the lower end of this grouping. An assessment of the beach measurements in the field gave a better correlation than the physical model results when compared to normalised predicted wave run up formulae. These measurements also plotted on the lower end of the grouping, resulting in prediction differences of less than 10% for some empirical formulae. When comparing these empirical predictions to one another, the results demonstrate that the formulae comparing best with the beach measurements were Holman (1986) and Stockdon, Holman, Howd, & Sallenger Jr. (2006). Extreme over predictions were found by Mase & Iwagaki (1984), Hedges & Mase (2004) and Douglass (1992). Nielsen & Hanslow (1991) only compared best with the beach measurements and De la Pena, Sanchez Gonzalez, Diaz-Sanchez, & Martin Huescar (2012) only compared best to the physical model results. This study supports the formula proposed by Mather, Stretch, & Garland (2011). Applying their formula to the measured results presented a C constant of 3.3 for the physical model and 8.6 for the beach results. Both values are within the range prescribed by the authors. Further reasearch minimized the array of possible „C‟ values by correlating this coefficient to Iribarren numbers. „C‟ values between 3.0~5.0 is prescribed for low Iribarren conditions (0.25-0.4) and values between 7.0~10 for higher Iribarren conditions are 0.75-0.8. However, this formula is still open for operator erros whereby the „C‟ value has a big influence in the final result. The best formulae to use, from results within this thesis, is proposed by Holman (1986) and Stockdon et.al (2006). These formulae are not open to operator erros and uses the significant wave height, deep water wave length and the beach face slope to calculate the wave run up.
AFRIKAANSE OPSOMMING: Gedurende die afgelope paar dekades, het golf-oploop voorspellings die aandag van talle navorsers gelok en elke nuwe geskrewe voorlegging het gepoog om meer akkurate golf-oploop voorspellings te verwesenlik. golf-oploop kan definieer word as die vertikale elevasie bereik deur 'n golf se voorwaterkant soos dit op die strand uitrol, gemeet relatief vanaf die stilwaterlyn. golf-oploop is afhanklik van die invals-golfhoogte, die golfperiode, die strandhelling en die golfsteilheid. Die oorgrote mederheid publikasies uit die literaturr inkorporeer al hierdie faktore, maar sommige nie, wat groot debatvoering tot gevolg het. Die doel met hierdie studie is om vorige gepubliseerde golf- oploop formules te re-evalueer, om 'n meer ingeligte begrip van golf- oploop en beskikbare voorspellende formules te verkry. Die studie poog terselfdertyd ook om golf-opvolg tendense, uniek aan Suid Afrikaanse strande te evalueer deur die huidige formule wat tans hier gebruik word, te assesseer. Om hierdie doelwit te bereik, is gebruik gemaak van 'n fisiese model toets reeks bestaande uit 10 reëlmatige golfstoestande op 'n konstante ondeurlaatbaare strandhelling van 1/24. 'n Veldstudie was ook uitgevoer op Langstrand, Noordhoek, waar golf-oploopmetings met 30 minute tussenposes uitgevoer is, vir vyf toets-toestande. Tesame met die veldstudie, is 'n numeriese model aangewend om die gemete diepsee data nader ann die strand wat bestudeer is te transformeer. Hierdie inligting is benodig om 'n verband tussen tussen oploop-metings en bekende golf parameters te bepaal. Eerstens is die fisiese model assessering uitgevoer om 'n behoorlike basis vir die begrip van golfoploop in die veld te verkry. Deur die emperiese, genormaliseerde oploop waardes (R₂/H₀) vir verkeie formules teenoor die Iribarren getal te plot, is 'n groepering met hoër en laer grense gevind. Daar is gevind dat die fisiese modelwaardes op die laer grens plot, en het verskille met die emperiese waardes van meer as 10% getoon. Hierdie verskille is moontlik veroorsaak as gevolg van 'n oneweredige fisiese model strandhelling of deur die feit dat slegs een helling getoets is. Ten spyte hiervan, het die model oploop waardes binne die bestek van golf- oploop formules geval. Assessering van die veldmetings het 'n beter korrelasie as die fisiese modelresultate getoon, tydens vergelykings met genormaliseerde golf-oploop formules van die emperiese formules. Die oploop waardes van hierdie metings het ook geplot aan die laer grens van die groepering, met verskille van minder as 10% vir die meeste gevalle van die emperiese formules. Wanneer hierdie emperiese voorspellings vergelyk word, is gevind dat die formules wat die beste ooreenstem met die fisiese model, die van Holman (1986) en Stockdon, Howd, & Sallenger Jr. (2006) is. Die emperiese formules van Mase & Iwagake (1984), Hedges & Mase (2004) en Douglas (1992) het die golf-oploop oorvoorspel. Nielsen & Hanslow (1991) het slegs die beste met die strandmetings vergelyk, terwyl De la Pena, Sanchez Gonzalez, Diaz-Sanchez & Martin Huescar (2012) slegs die beste vergelyk het met die fisiese-model resultaat. Hierdie studie ondersteun die formule voorgestel deur Mather, Stretch, & Garland (2011). Deur hul formules op die gemete bevindings toe te pas, is 'n C konstante van 3.3 vir die fisiese model resultate, en 8.0 vir die stranduitlslae bepaal. Beide waardes lê binne die grense wat deur die outeurs voorgestel is. Verdere navorsing het getoon dat moontlike waardes vir die „C‟ konstante tussen 3.0 en 5.0 moet wees vir Iribarren waardes van tussen 0.25 en 0.4. Vir hoër Iribarren waardes, 0.75-0.8, moet die „C‟ kosntante tussen 7.0 en 10 wees; dog is die formule steeds oop vir operateur foute. Die hoofbevindinge van die tesis is gevind dat die beste golf-oploop formules, om tans te gebruik, die van Holman (1986) en Stockdon et.al (2006) is. Hierdie formules kan glad nie beinvloed word deur operateurs foute nie en maak gebruik van die invals golfhoogte, die golfperiode en die strandhelling om die golf-oploop te bepaal.

Bibliography: leaves 41-47.Patterns of morphological variation were investigated in the genus Merciera A.DC. to re-assess the species boundaries. This study differs from previous studies in the genus because it employs multivariate statistical methods. Vegetative and floral characters obtained from herbarium specimens were analyzed. The results of the cluster analysis and principal coordinate analysis support the recognition of six species, M. /ept%ba, M. brevifolia, M. tenuifolia, M. eck/oniana, M. azurea, and M. tetra/oba. M. azurea is re-instated as a species and a new species M. tetra/oba is described. An infra-generic phylogeny for the genus is proposed for the first time. A key to the species, descriptions, and distribution of all the species are also provided.

Full textAbstract:
The imminent threat of global catastrophe due to climate change gets more real by each passing year. The Aviation trade association, IATA, claims that Aviation accounts for approximately 2% of the Greenhouse Gases (GHG) caused by human activities, and 3.5% of the total Radiative Forcing. With continuous increase in Aviation industry and subsequent drop in fossil fuel prices, these numbers are only expected to up with time. In Addition, these numbers do not include the effects of altitude of emission and many environmentalists believe that the number for some pollutants could be at least 2-3 times larger than IATA estimates. This rising concern engages the Aviation industry to investigate possible methods to alleviate their environmental impact. The first part of this thesis provides a framework to support Airlines in monitoring their current environmental footprint during the process of scheduling. This objective is realised by developing a robust system for estimating the fuel consumed (ergo quantity of major Greenhouse Gases emitted) by a particular fleet type operating a certain leg, which is then employed in a Fleet Assignment (FA) Operation to reduce emissions and increase the Contribution. An emissions estimation model for Turbojet Aeroplane fleets is created for Industrial Optimizers AB’sMP2 software. The emissions estimation model uses historic fuel consumption data provided by ICAO for a given fleet type to estimate the quantity (in kg) of environmental pollutants during the Landing and Takeoff operation (below 3000 ft) and the Cruise, Climb and Descent operation (above 3000 ft). The second part of this thesis concerns with assigning monetary weights to the pollutant estimates to calculate an emission cost. This emission cost is then added to MP2’s Fleet Assignment’s objective function as an additional Operational cost to perform a Contribution maximization optimization subjected to the legality constraints. The effects of these monetary weights levied on the results of Fleet Assignment are studied, and utilizing curve-fitting and mathematical optimization, monetary weights are estimated for the desired reduction in GHG emissions. Finally, a recursive algorithm based on Newton-Raphson method is designed and tested for calculating pollutant weights for untested schedules.Det omedelbara hotet om en global katastrof pga klimatförändringar blir mer och mer tydligt för varje år som går. IATA, den internationella flyghandelsorganisationen, hävdar att flyget står för runt 2% av växthusgaserna (GHG) som kommer från människans aktiviteter, och 3.5% av den totala avstrålningen. Med den kontinuerliga tillväxten av flygindustrin och prisminskningar av fossila bränslen så förväntas dessa andelar att öka. Dessutom så inkluderar inte dessa siffror effekten av att utsläppen sker på hög höjd, och många miljöaktivister tror att siffrorna för vissa utsläpp kan vara åtminstone 2-3 gånger högre än IATAs uppskattningar. Denna växande oro motiverar flygindustrin till att undersöka metoder för att begränsa dess miljöpåverkan. Den första delen av denna rapport ger ett ramverk för att hjälpa flygbolag med att bevaka deras aktuella miljöavtryck under schemaläggningsprocessen. Detta mål realiseras genom att utveckla ett robust system för att uppskatta bränsleförbrukningen (och därmed kvantiteten av växthusgasutsläpp) av en specifik flygplanstyp på en given etapp, som sedan kan användas för att allokera flygplanstyper för att minska utsläppen och bidra till att förbättra miljön. En modell för att uppskatta utsläpp för flottor av turbojetflygplan har skapats för Industrial Optimizers AB programvara MP2. Modellen för att uppskatta utsläppen baseras på historiska data om bränsleförbrukning som tillhandahållits av ICAO för en given flygplanstyp som använts för att uppskatta kvantiteten (i kg) av föroreningar vid start (under 3000 fot) och vid sträckflygning, stigning och inflygning (över 3000 fot). Den andra delen av denna rapport handlar om att bestämma monetära vikter till föroreningsskattningarna för att beräkna utsläppskostnader som ska användas i MP2 s målfunktion för allokering av flygplanstyper. Detta ger en ytterligare driftskostnad att beakta i optimeringen för att få med miljöaspekterna och tillåtna lösningar. Effekten som dessa monetära vikter har på resultaten från optimeringen studeras, och genom att använda kurvanpassning och matematisk optimering, de monetära vikterna anpassas för att få den önskade minskningen i växthusgasutsläpp. Slutligen så har en rekursiv algoritm, baserad på Newon-Raphsons metod, designats och testats för att beräkna utsläppsvikter för scheman som inte använts för att beräkna vikterna

Full textAbstract:
The thesis propose a new design solution of the web application and air assessment tool: SIMAIR, a product of The Swedish Meteorological and Hydrological Institute (SMHI). The current solution of SIMAIR is outdated regarding the interaction and visual apperance, as a result it is in need of a user adaption. No user study has been perform earlier and for that reason SMHI needs an increased knowledge about the users. The objectives of this thesis are therefore to perform a user study, develop a more user-friendly design and implementan interactive prototype of the new design solution. By using the design method Goal-Directed Design, a design target of the wide spread user group was found and personas of the user archetypes were developed. By narrowing down the target audience, the new design was more well defined and the chances to create a product that satisfied the users' needs increased. The design target and the personas was used to find goals and motivations, as well as aptitudes and attitudes, of the users. "Seriousness", "Professionalism" and "Reliability" were the objectives for the new design. They formed the basis for the creation and development of a modernized and user-friendly graphical user interface of SIMAIR. The prototypeto visualize the new interface, was developed by using HTML5, CSS3 and the JavaScript libraryJQuery. These technologies are also, well suited for further development and usability improvement of SIMAIR.

Bina, Olivia Claudia. "Re-conceptualising strategic environmental assessment : theoretical overview and case study from Chile." Thesis, University of Cambridge, 2004. https://www.repository.cam.ac.uk/handle/1810/245008.
Full textAbstract:
Strategic Environmental Assessment (SEA) has a prominent position in the ongoing search for instruments that can help governments and other organisations to pursue the complex goal of sustainable development. Academic literature and practitioners have devoted increasing attention to this instrument since the late 1980s, and the mid- 1990s have witnessed a surge in legislation and methodological guidance throughout both developed and developing countries. However, the theoretical basis of this instrument remains weak and this thesis contends that the actual reason for its existence (raison d'être) of SEA is inadequately conceptualised. The first stage of the research critically reviews the theory and practice of SEA, identifying tensions, weaknesses and promising trends in the concepts underlying its three dimensions: strategic, environmental and assessment. These show that the idea that there is something 'strategic', whose environmental effects should be assessed - is misleading, as well as simplistic, thus supporting the call for a re-conceptualisation of SEA. The meaning of two common claims (that SEA is to contribute to sustainable development and to the improvement of policy-making processes) in academic and policy literatures is explored in detail. Combining environmental assessment literature with work related to the knowledge perspective of policy-making, policy learning and policy analysis, the thesis then develops a series of propositions for a new interpretation of SEA's raison d'être. These relate to four themes: context, object, purpose and assessment. The second stage seeks to deepen the understanding of the trends and propositions identified, and to verify their relevance in a developing context. Using a range of methods, from interviews to seminars, a case study of Chile - a middle-income country - investigates the interpretation of the purpose and role of SEA according to a range of stakeholders, and in more detail within the Ministry of Public Works. This leads to the proposition, and testing, of a framework that emphasises the need to interpret and operationalise SEA at the level of organisations (such as ministries or multi-lateral development agencies), not of economic sectors alone. It centres on the interactions of the context, the nature of strategic objects, the framing of 'environmental', the purpose of SEA, and the assessment's approach and tools. The most important conclusion is that SEA can only facilitate more environmentally sustainable forms of development, if conventional wisdom about its raison d'être is questioned. This thesis rejects the rhetorical claims in normative interpretations of SEA which identify strategic initiatives, and particularly policies, plans or programmes, as the defining feature of SEA, and the main meaning of its 'strategic' dimension. It proposes that the context, and in particular organisations, should be the focus of a new conception of SEA which seeks to institutionalise rational and argumentative learning as a means to promote environmentally sustainable policy-making. These findings therefore contribute to both the theory and practice of SEA.

Full textAbstract:
Magister Artium (Development Studies) - MA (DVS)In recent years, urban growth has been one of the major challenges in Africa. The increasing size and unwieldiness of towns and cities are a result of an on-going rapid urbanisation. The process of this rapid urbanisation in Africa is driven by the pursuit of employment and a better standard of living, which is rarely offered or available in rural areas (Okeke, 2014). Urbanisation brings about better services and livelihoods to millions, but poverty remains high in the rural and urban areas of Africa. Urbanisation is defined as an increase in the percentage of people living in towns and cities, which takes place as people move from rural to urban areas for better living standards. Urbanisation increases as a result of the extent and density of the cities.

Full textAbstract:
The shear strength of the concrete-rock interface is an important parameter in sliding stability analyses of concrete dams founded on rock and depends, in addition to the normal stress state, on the bonding conditions of the interface; concrete-rock interfaces can be either unbonded, partially bonded or fully bonded. In the Swedish guidelines for dam safety all dam-foundation contacts are treated as unbonded. This has the benefit of eliminating all uncertainties related to the cohesive strength of bonded contacts but it might also lead to unnecessary strengthening of dams. Other national guidelines deal with the uncertainties related to cohesion by applying higher safety factors, mainly determined based on previous experience, when both cohesion and friction are taken into account. The main objective of this project is to study if and how cohesion can be included when evaluating the shear strength of bonded or partially bonded interfaces. To accomplish this, uncertainties associated with cohesion are identified and their influence on the assessed stability is investigated. The results show that the influence on the assessed sliding stability is strongly dependent on the magnitude of the involved uncertainties that might vary significantly for different dams. It is thus questionable if one safety factor applicable for all dams can be established for use in deterministic analyses. Taking into account cohesion when reliability methods are used is somewhat less complicated because of the possibility of directly incorporating the uncertainties in the analysis. The main challenge in such cases is the quantification of the involved uncertainties due to lack of proper data and, in some cases, knowledge. In this thesis, a framework for quantification of parameter uncertainty is suggested and the model error due to brittle failure in combination with spatial variation in cohesion is analysed. Areas that require more research to further refine the analysis are also identified.Skjuvhållfastheten i betong-berggränssnittet är en avgörande faktor vid glidstabilitetsutvärderingar av befintliga betongdammar grundlagda på berg och beror dels på normalspänningsfördelningen och dels på kontaktytans status med avseende på vidhäftning, vilken kan delas in i tre separata fall; då vidhäftning existerar och kohesion medräknas (intakt), då vidhäftning aldrig funnits eller förlorats (bruten), samt en kombination av föregående (delvis intakt). I RIDAS, de svenska riktlinjerna för dammsäkerhet, behandlas alla berg-betonggränssnitt som brutna. Detta förhållningssätt har fördelen att det utelämnar all osäkerhet förknippad med intakta kontaktytors kohesion men det kan också resultera i icke nödvändiga förstärkningar av dammar. I andra nationella riktlinjer för dammsäkerhet beaktas osäkerheterna förknippade med kohesion genom att högre säkerhetsfaktorer, i huvudsak bestämda baserat på erfarenhet, tillämpas då både kohesion och friktion används vid beräkning av kontaktytans skjuvhållfasthet. Det övergripande syftet med detta doktorandprojekt är att studera om och hur kohesion kan medräknas vid stabilitetsutvärderingar av befintliga betongdammar med helt eller delvis intakta betong-berggränssnitt. För att uppnå detta, identifieras osäkerheter förknippande med kohesionen och deras inverkan på den bedömda glidstabiliteten utvärderas. Resultaten från projektet visar att osäkerheternas inverkan på den uppskattade glidstabiliteten är starkt beroende av osäkerheternas storlek, vilken varierar för olika dammar. Det är således tveksamt om en säkerhetsfaktor giltig för alla dammar kan bestämmas för användning i deterministiska stabilitetsanalyser. När sannolikhetsbaserade metoder används kan osäkerheterna införlivas direkt i analysen. Kvantifieringen av osäkerheterna förknippade med ett specifikt fall utgör då den huvudsakliga utmaningen. I denna avhandling presenteras ett ramverk för att uppskatta de statistiska parametrarna hos de ingående variablerna.

Full textAbstract:
Some recent studies have suggested that fertility decline has slowed down in several sub-Saharan Africa countries, but have reached contradictory conclusions. This thesis re-assessed fertility trends in 17 sub-Saharan African countries over two decades. The first part of this study examined the data quality of 63 Demographic and Health Surveys. Date and age misreporting, particularly age displacement of children, was prevalent and the degrees varied across the surveys within the countries, which have affected fertility trends. Using a Loess regression and adjusting for common errors, trend estimation methods were introduced. The new methods produced both robust trend estimates and uncertainty intervals. The results pointed out the limitations of DHS data for trend estimation and the weakness of the earlier studies. In six countries the pace of decline has more than halved since the 1980s, but no country has it ceased entirely. The second part of the thesis proposed modifications in Bongaarts’ proximate determinants framework and applied them in order to explore the extent to which changes in proximate determinants support the Loess fertility trends. The results suggested that the changes in each proximate determinant varied greatly across the countries, and other proximate determinants, apart from contraception, have played important roles in inhibiting fertility in the region. Changes in sexual activity among married and unmarried were found. Overall, the trends of the TFR estimates from the proximate determinants framework were consistent with those of the Loess estimations. Specifically, the projected TFRs in the five countries (Benin, Kenya, Malawi, Nigeria and Zambia) where the Loess estimates depicted deceleration also failed to decline in the same periods. The study recommends careful assessments of fertility trends using the rigorous methods, balancing the quality and quantity of questions in the DHS Questionnaire, and further research on marriage and family systems in sub-Saharan Africa.

Full textAbstract:
Background Asthma is a public health problem in Latin America, where asthmatic children are mainly treated at emergency rooms during acute attacks. These attacks result in loss of lung function and quality of life for the asthmatic child and family, risk of death and high direct and indirect economic costs. In order to improve paediatric asthma management in Esmeraldas, Ecuador, we aimed to identify predictors of recurrent asthma attacks requiring emergency care and to explore the caregivers’ (CGs) and health care workers’ (HCWs) perceptions of barriers and facilitators to asthma health and home care access. Methods First, a systematic review and meta-analysis of published studies analysing predictors for emergency department (ED) re-attendance or hospital readmission for acute asthma in children was performed. Second, a prospective cohort study of children treated for an asthma attack at an emergency room in Esmeraldas, Ecuador, was undertaken to define the characteristics of these children, determine the rate of ED re-attendance for acute asthma and identify the predictors for this to occur. Third, a qualitative study to explore acute asthma significance and perceived barriers and facilitators for health and home care access from the asthmatic children’s CGs’ and HCWs’ perspective was performed. Results In both the meta-analysis and prospective cohort study, children of a younger age and a history of severe asthma attacks during the previous year were at a greater risk of ED re-attendance for acute asthma. Forty six percent of the children recruited during the prospective cohort suffered a subsequent asthma attack requiring emergency care in the following 6 months. Other identified predictors of ED re-attendance for acute asthma were: existing asthma diagnosis (AOR: 2.17, 95% CI: 1.19-3.94; AHR: 1.66, 95% CI: 1.15-2.39); food triggers (AOR: 1.99, 95% CI: 1.11-3.55); existing eczema diagnosis (AOR: 4.22, 95% CI 1.02-17.54); and urban residence as protective (AHR: 0.69, 95% CI: 0.50-0.95). Twelve HCWs and 20 CGs participated in the in-depth interviews and focus group discussions, expressing a differing significance of asthma attacks. This difference was also observed between experienced and inexperienced HCWs. Multiple barriers and several facilitators were identified by HCWs and CGs that affect health and home care access for asthmatic children. When shown the predictors of ED-reattendance for acute asthma combined in a risk-assessment tool, both HCWs and CGs reported finding the tool easy to use and understand, as well as a useful aid in the decision-making process concerning asthma treatment and follow-up. Conclusion A combination of several question-based predictors may result in an effective and simple risk-assessment tool to be used at the ED to identify asthmatic children at a higher risk of recurrent severe asthma attacks. Increasing CGs’ and HCWs’ asthma knowledge as well as HCWs’ communication skills, to establish a patient centred approach with a shared decision-making process could mean a difference in the quality of the asthma care in this setting. The use of the described recurrent risk assessment tool could prove useful in this process, as reported by the participants in this study.

Full textAbstract:
Space re-entry is a challenging endeavor due to the harsh thermo-chemical environment around the vehicle. Heat flux being the reference parameter for Thermal Protection System (TPS) design, the total energy transfer can significantly increase due to the exothermic atomic recombination enhanced by TPS catalytic properties. The catalytic recombination coefficient modelling is critical for heat flux computation during TPS design.
This work assesses the ability to determine the recombination coefficient at Von Karman Institute's (VKI) plasma wind tunnel (Plasmatron) as a step towards future validation of catalytic models : from a reference catalytic model development for enthalpy characterization of the facility, to the identification of the most influential parameters found in non-equilibrium boundary layers.
Plasmatron test results encourage a flight extrapolation strategy development in order to link the catalysis measured on ground to the catalysis appearing in flight. The strategy, focused on off-stagnation point conditions, shall contribute to future post-flight activities of the CATalytic Experiment (CATE) on board of the Intermediate eXperimental Vehicle (IXV). Relevant data from IXV and CATE are also presented, laying the foundation for for future developments at VKI.

Full textAbstract:
Although the works of Christine de Pizan have been of interest to scholars for some time, technological advances and initiatives to make digital copies of manuscripts available online have only recently enabled close comparisons between the visual programmes of her works to be made. This thesis demonstrates that detail usually considered secondary or 'paratextual' in Christine's manuscripts actually formed a carefully-constructed part of the work itself that Christine explicitly asks her audience to read. Through 'reading' the text and image simultaneously, the visual programme proves to comprise additional layers of meaning that were woven into her didactic works. These meanings can serve to supplement the educational and moral aims of the works, or, conversely, can be inconsistent with the message conveyed in the text, leading the reader-viewer to contemplate further on the matters presented and form their own opinions on them. Sometimes, meaning is created by intervisual connections with pre-existing iconography, such that viewers may be creating associations between the miniatures seen in Christine's manuscripts and other imagery, leading them to make certain associations - this is notably the case in author-portraits of Christine. As manuscripts prepared under the author's supervision came to be copied, changes were made to the iconographic programmes, testifying to and enabling different types of readings to take place. The findings of this thesis have implications for editorial practices of medieval works in general, as these tend to circulate in editions without the visual programme, providing modern readers with only a partial view of the complete work.

Full textAbstract:
Magíster en Ciencias, Mención AstronomíaLa distribución de galaxias a gran escala define una compleja red de filamentos, murallas y vacíos de galaxias, situándose los cúmulos de galaxias en la intersección de filamentos. A dicha red se la conoce como “Estructura a Gran Escala” (LSS por su sigla en inglés), cuya forma general y relación entre sus componentes provee información sobre la distribución general de materia, que depende del modelo cosmológico, y la formación de las galaxias, siendo necesario perfeccionar continuamente su caracterización en la medida que hay avances significativos en las bases de datos o en los métodos de análisis. Nuestro trabajo esta basado en el reciente catálogo VOCLUDET de cúmulos y grupos de galaxias, construido en forma automatizada a partir del catálogo de corrimientos al rojo de galaxias llamado “2-degree Galaxy Redshift Survey” (2dFGRS) mediante el metodo geometrico de Voronoi, el cual consta de dos secciones, una norte, del North Galactic Pole (NGP), y una sur, del South Galactic Pole (SGP). La utilización de cúmulos de galaxias en el trazado de la LSS tiene las ventajas, frente al uso directo de las galaxias, por no estar ellos afectados por el efecto distorsionador llamado “Dedos de Dios” (Fingers-of-God) y porque se pueden estimar individualmente sus masas totales. A partir de un análisis exhaustivo del catálogo VOCLUDET, se definio una muestra de 745 cúmulos caracterizados por altos valores de su dispersión de velocidad (HVDCS por su sigla en inglés), > 400 km/s, correspondientes por lo tanto preferentemente a cúmulos masivos. Nuestro análisis indica que las propiedades de los cumulos de esta muestra no presentan un efecto de selección importante con la distancia, hasta aquella correspondiente a z~0.15, por lo que en este trabajo hemos limitado el mapeo de la LSS hasta z~0.15. Incluimos el catalogo de la muestra HVDCS en este trabajo, que consiste en el listado de los siguientes parametros calculados: ascensión recta, declinación, redshift, distancia comóvil, Ngal, v , masa virial, radio promedio. Para obtener el trazado de la estructura a gran escala hemos calculado, en 3 dimensiones, el Árbol Recubridor Mínimo (Minimal Spanning Tree, MST), el cual es un trazador cuantitativo y objetivo de la LSS, revelando la estructura filamentaria de las cadenas a las cuales pertenecen los cúmulos de la muestra HVDCS. El análisis de las propiedades del MST de la distribución de estos cúmulos indica que la topología global de su distribución espacial es consistente con una distribución con una geometría filamentaria a escalas mayores que la distancia promedio entre cúmulos y de una geometría tipo plano a escalas más pequeñas. Usando el mismo MST, realizamos una búsqueda sistemática de supercúmulos en el 2dFGRS. Nuestro catálogo de supercúmulos en el 2dFGRS consiste en 55 y 73 detecciones de supercúmulos en las secciones NGP y SGP, respectivamente. Se estimó la significancia estadística de cada supercúmulo y se extrajo una muestra de supercúmulos de alta significancia en su detección, consistente de 35 y 49 supercúmulos en el NGP y SGP, respectivamente. Hemos encontrado que la mayoría de los supercúmulos identificados tienen algún grado de correspondencia con aquellos de catálogos de supercúmulos previos en el volumen del 2dFGRS. Del estudio de la geometría y población de nuestros supercúmulos encontramos que los supercúmulos pobres, constituidos por menos de 10 cúmulos de galaxias, son muy numerosos y filamentarios, formado por simples cadena de cúmulos, mientras que los superćumulos ricos son muy escasos, con un gran número de cúmulos y poseyendo en su interior cadenas de cúmulos “tipo araña”. Incluimos el catalogo de los supercúmulos encontrados en este trabajo, que consiste en el listado de los siguientes parámetros calculados: ascensión recta, declinación, redshift, distancia comóvil, Ncl, p-value del test de significancia, cúmulos miembros, filamentariedad del grafo, largos de los ejes principales y volumen del elipsoide envolvente, y los descriptores de forma y la triaxialidad.

Full textAbstract:
This thesis examines the role of internal auditors in three key areas: strategy, control models and control self assessment. Research findings are based on the results of a survey of a specialist group of professionals with an interest in Control Self Assessment. This group comprises both internal auditors and non-internal auditors. Membership is multinational and a full range of industries is represented. The actual and potential contribution that internal auditors can make to strategy is assessed and evaluated, with particular reference to the Balanced Scorecard. Control models were examined to identify use and effectiveness and the potential link with successful implementation of Control Self Assessment. Control Self Assessment was also examined as a specific activity. This part of the research addressed how it was perceived by the respondents and their organisations, and also to examine the importance of facilitation skills and IT support. The results show that internal auditors already play a significant role in strategic issues, and that there is a significant awareness of the potential benefits of the Balanced Scorecard to internal audit practice. Control models are seen as highly important to the effective implementation of Control Self Assessment, which can be seen to have developed into a mature and established audit tool.

Full textAbstract:
Jerome Bruner (1990) issued a call for psychology to abandon its preoccupation with the Newtonian scientific paradigm and to return to first principles by directing its attention to intentionality in general, and meaning in particular. Needless to say, intentional predicates such as meaning, understanding, learning, thinking, remembering, believing, and so on, are also of central concern to education. This thesis takes up Bruner's challenge by appealing to the philosophical writings of Bohr and the later Wittgenstein. Bohr was adamant that the prope11ies of intentional predicates fit the framework of quantum theory, which superseded Newtonian mechanics as the best model of physical reality in the early pat1 of the twentieth century. Wittgenstein's later philosophy of psychology contains an extensive analysis of the nature of intentional predicates. At odds with Bruner's first-person "theory of mind", the author draws on the writings of Bohr and Wittgenstein to identify a first-person/third-person asymmetry governing all intentional predicates. The ideas of these two influential twentieth century thinkers are used to identify four misconceptions in contemporary educational (and psychological) thinking. It is argued that measurement in education and psychology is not a matter of checking up on something already in existence; rather, the measurer pat1icipates in what he or she observes. In these circumstances, strong objectivity yields to weak objectivity. The construct measured and the measuring instrument cannot be meaningfully divided, and a more profound link between assessment and learning is established. The thesis makes the case that paradoxical difficulties attend the notion that learning established concepts is tantamount to getting mental entities in mind. Psychology and education have a tendency to treat human capacities as mental states. The author makes the case that the capacity to participate in a range of disciplinary practices is the criterion for having learned an established concept. The author questions the frequently encountered contention that teaching which involves training pupils to apply the paradigm examples of science and mathematics, for example, (what Dewey characterised as "pouring in ") is little more than behavioural conditioning. Finally, pace progressivist thinking, the thesis makes the case that children go to school to acquire a framework which constrains otherwise untrammelled creativity.

Full textAbstract:
This thesis is concerned with a range of Japanese expressions which have been classified in traditional Japanese studies as marking causal relations between segments of discourse: dakara, sorede, tsumari, sunawachi, yahari and kekkyoku. I argue that this traditional approach, which has an affinity with coherence based analyses of (mostly) English discourse connectives, is not adequate either at a descriptive or an explanatory level. On the one hand, it predicts that expressions which fall into the same class are intersubstitutable in all contexts, which they are not. On the other hand, it cannot sxplain why expressions within a category are at once so similar and yet so different.

Full textAbstract:
This thesis examines the effectiveness of general re-offending risk assessment instruments for young people. The introductory chapter considers current trends in Scottish youth crime and provides an overview of the unique way in which children and adolescents are dealt with through the Children's Hearing System (Social Work Scotland Act, 1968). Chapter two presents a systematic literature review of the risk and protective factors associated with repeat offending and desistance in adolescent offending behaviour. This was deemed necessary as previous adolescent reviews have focused on factors associated with the onset of offending and have neglected to identify those factors associated with continued involvement in crime. Chapter three provides a critical review of the 'Asset' risk of general re-offending risk assessment measure. This critique was conducted as 'Asset' has routinely been used for the past 13 years across the UK to identify community and custodial disposals for young people involved in criminal behaviour, and it is the measure of risk used in the research element of this thesis. Chapter four comprises an empirical research study, which compares the predictive validity of 'Asset' with that of the Youth Level of Service-Case Management Inventory (YLS-CMI) in a sample of Scottish youths. Each instrument predicted general repeat offending with moderate ('Asset' Area Under the Curve (AUC) =0.75) to large effect sizes (YLS-CMI AUC =0.81). Finally, chapter five summarises the findings from the previous chapters, considering potential implications for the development of policy and practice, and recommendations for future research.

Full textAbstract:
In a stroke-certified 500-bed acute care hospital, the 30-day readmission rates for patients discharged to rehabilitation centers or skilled nursing facilities were higher than the rates for patients discharged to home. A review of data by the stroke team showed 44 patients readmitted within 30 days of initial stroke discharge between October 2016 and January 2017. The rate of re-admission for those discharged home was 41% (18 patients), whereas the rate for those discharged to acute inpatient rehabilitation, long-term acute care, or skilled nursing facilities was 59% (26 patients). The practice-focused question for this project assessed whether using a re-admission risk-assessment tool and implementing interventions during the initial acute-care admission, would help to identify and improve risk for 30-day re-admissions for patients diagnosed with stroke. The goal of this research project was to adopt, test, and recommend the implementation of a readmission risk assessment tool to enable discharge planners to identify stroke patients at risk for readmission and implement interventions to help reduce this risk. Lewin’s theory of change was used to inform the project. A stroke re-admission risk-assessment tool in use at a similar hospital was adopted and tested for 1 week on the hospital’s 28-bed stroke unit by nurse case managers. The test was conducted among 5 patients with confirmed diagnosis of stroke. A re-admission data review was performed 30 days after their discharge, which showed no readmissions for the 5 patients involved in the trial. The tool helped to improve case manager awareness of increased risk for readmissions, guide interventions, and improve patient transition and outcomes. The implications of this project for positive change include the potential to improve risk for patients with stroke in the acute-care facility.

Full textAbstract:
Re-powering solar PV plants is an upcoming discussion on the global stage. Although the respective component warranties indicate the time to change the system machinery, the methodology and justification for carrying this out are two aspects that need further study. The rooftop solar PV system on top of Dalarna University was re-positioned in 2014. Prior to installing the system in its new position, the system arrays were reconfigured and new inverters were installed. This thesis aimed to compare and analyze two sections of the solar power plant to understand which amongst them performs better. Graphs depicting energy, current, voltage and other parameters were formulated to ascertain the efficacy of the array configurations for this Nordic latitude. Thereafter, PVsyst and SAM were used to compare the simulated results with the actual output from the system. It was found that the measured energy output from one section of the solar power plant was higher than that of the other during 2014. On an annual basis, this difference was 21.5 kWh or 2%. On closer inspection, this contrast was attributed to a difference in yield early in the morning. Further, PVsyst simulated the annual energy with a deviation of less than 1% than what was measured, whereas SAM measured a deviation in energy measurement of 2.5% higher than the actual measured energy. These values were obtained using the detailed design options for both softwares. A point to keep in mind is that prior experience of working with both these softwares is recommended prior to carrying out the simulations on these softwares. An underlying point to note in this study is its limitations. This study is valid in the northern latitudes, such as the Nordic climates, since other regions would not have such low (sub-zero) temperatures to account for while sizing the inverter. In regions of high irradiance, a system re-powered in a way such as the system in this case would have higher clipping losses. Relevant previous studies and related topics have been visited, summarized and cited.

Thomas, Jane. "Re-constructing children's identities : social work knowledge and practice in the assessment of children's identities." Thesis, Cardiff University, 2010. http://orca.cf.ac.uk/55064/.
Full textAbstract:
This thesis is an exploration of how social work practitioners learn about and assess children's identities within the Core Assessment process contained within the Framework for the Assessment of Children in Need and their Families. A qualitative case study was conducted within one childcare team in a local authority in South Wales with participation from key stakeholders involved in the assessment process: practitioners, parents, carers, and the subject children. Thirteen social work practitioners and eleven parent/carers participated in semi-structured interviews that explored what they understood identity to mean together with their appraisals of assessments of children's identities. Access to children was gained with consent of the parent/carers, with ten children taking part in a multi-method research strategy aimed at ascertaining children's own accounts of their identities. Core Assessment documents and interview data were analysed utilising textual analysis. The data from the children has been reproduced, wherever possible, verbatim to ensure their voices are made prominent within the study. The key findings are that the assessment of children's identities is an intricate, iterative task that poses practitioners with considerable practical and moral issues. Practitioners appear to utilise artistry in their management of the assessment task, commonly not making explicit the sources upon which their assessments of children's identities are based. It would appear that practitioners prefer to present their assessments of children's identities in the form of a narrative account, of which ownership of the details remains very much in the hands of the practitioner. Within this thesis subtle yet important differences between how practitioners, parents, carers and children construct identities is unearthed. It is posited that practitioners' assessments of children's identities do not reflect the individuality of the child and the reasons for this are explored. Also the adequacy of the Assessment Framework as a tool for assessing children's identities is questioned. It is suggested that the Assessment Framework restricts practitioners' assessments of children's identities to little more than constrained accounts of any child: thus ignoring the uniqueness of the subject children. It is demonstrated that in using the Assessment Framework, practitioners often struggle to employ their own nuanced knowledge of the subject child. The complexities practitioners encounter in managing the task of assessment is considered. Some practitioners appear to invoke some sense of the fluidity and subjectivity of identities, suggesting an appreciation that there may be many different ways to perceive another. Other practitioners assert some singular and true identity that should be unearthed though the assessment process. More generally, the thesis reveals that practitioners typically construct children's identities within the familiar framework of developmental and object-relational theories. The implications of this for children to be constructed as passive objects, whose identities are seen as more simplistic, less sophisticated than adult identities, is critically examined. The limits and potential of contemporary assessment practices with regard to children's identities is also explored. It is suggested that greater inclusion of the views of parents, carers and subject children in assessment is needed if practitioners are to move away from a constrained re-construction of children's identities and to present instead accounts that more authentically reflect the individual identities of the subject children.

The decline of the WCRL fishery in recent decades has been accompanied by the restructuring of the permit process to a long-term rights allocation process and the increased participation of historically disadvantaged individuals. This paper examines the effects of declining somatic growth rates and stock abundance over the years, increased levels of poaching, and the placement and effectiveness of marine reserves, on the WCRL industry, which incorporates the offshore and nearshore commercial fisheries and the recreational fishery. Small-scale traditional fishermen face access constraints to the fisheries, including lack of skills, limited access to credit and insufficient organisation. Sustainability of both the resource and fishery-based livelihoods must be ensured when examining the social and economic impacts underlying the recent legal issue between MCM and the large rock lobster firms who were contesting the allocation of permits to nearshore fishermen. There is currently an attempt to resolve this ongoing conflict by the drafting of a small-scale fisheries policy. New focuses in the industry include introducing an ecosystem-based management approach by 2012, commitment to co-management, and marine protected areas, particularly a call for increased use of no-take reserves.

>Magister Scientiae - MScThe Saldania Belt in southern Africa, a product of the Pan-African Saldanian Orogeny, forms part of a system of Neoproterozoic mobile belts that border and weld older cratons on the African continent. It is a low-grade orogenic belt situated along the southwestern margin of the Kalahari Craton and is composed of several inliers of greenschist facies metasedimentary and metavolcanic rocks (Malmesbury Group), unroofed in megaanticlinal hinges of the Permo-Triassic Cape Fold Belt. The Malmesbury Group rocks were syn- and post-tectonically intruded in a pervasive transpressive regime between 555 Ma and 515 Ma by Neoproterozoic to early Cambrian S-, I- and A-type granites, monzodiorites, gabbros and quartz syenites, which collectively constitute the rocks of the Cape Granite Suite (CGS). Along the south-western coastline of South Africa, the Saldanha Bay Volcanic Complex (which forms part of the CGS) is divided into two eruption centres both of which have been identified as “intra-caldera pyroclastic ignimbrites”. The Postberg eruption centre is situated to the south of the Saldanha Bay entrance and the Saldanha eruption centre is situated to the north of the entrance. Both eruption centres display distinct geochemical signatures, the most apparent being the greater TiO2 concentrations (> 0.25 wt. %) of the Saldanha centre ignimbrites when compared to its Postberg centre counterparts. The Postberg eruption centre consists of S-type rhyolitic ignimbrites which are subdivided into the two geochemically distinct Plankiesbaai and Tsaarsbank Ignimbrites. Small amounts of the Jacobs Bay and Saldanha Ignimbrites (less felsic tephra from the Saldanha eruption centre) are also present in the Postberg eruption centre. A robust geochemical analysis of both the Plankiesbaai and Tsaarsbank magma groups display high SiO2 content (>76 wt. %), a lack of variation in TiO2 and Zr, high Al2O3 and ASI (aluminium saturation index) values (> 1.0 and generally >1.1 which, on average, is higher than the Saldanha eruption centre ignimbrites), low CaO and Na2O, and a highly ferroan character. The Plankiesbaai ignimbrite also display lower #Mg concentration compared to the Tsaarsbank ignimbrite. Typical geochemical trends in the Postberg eruption centre include the lack of variation in Zr content, higher Rb content and lower Sr, Ba, V and Zn concentrations when compared to the tephra of the Saldanha eruption centre found in the Postberg area.

Full textAbstract:
Efforts to manage eutrophication of surface waters should recognize that macropore flow transports significantly more phosphorus (P) to surface waters via tile drains than water that percolates through the soil matrix. For the watershed-scale SWAT (Soil and Water Assessment Tool) model to describe phosphorus transport through tile drains, SWAT needs to partition percolation into macropore flow and matrix flow. The objective of this study was to evaluate the effects of a new macropore flow algorithm on the partitioning of hydrological flows, using input data that are readily available, consistent with the current approach to SWAT modeling. The algorithm was evaluated in a proof of concept outside of SWAT and within a re-conceptualized version, SWAT-QC2. The proof of concept reproduced episodic macropore flows, which increased with greater daily rainfall if infiltration exceeded a threshold that was lower for finer-textured soils. Although the algorithm did not improve predictions of streamflow of an agricultural subwatershed in southern Quebec (30 km2), the algorithm improved SWAT's partitioning between surface runoff and subsurface flow. SWAT-QC2 also predicted reasonably the separation between macropore and matrix components of subsurface flow, upon comparison with results from a chemical-based hydrograph separation of the subwatershed's streamflow. As in the proof of concept, the predicted amount of macropore flow into tile drains was greater under finer-textured soils than coarser-textured soils. By describing the portion of percolation that flows through macropores and potentially controls subsurface P transport, the macropore flow algorithm provides a framework for future developments of SWAT that describe macropore transport of P to tile drains. To improve the partitioning between macropore and matrix flows, future developments of SWAT-QC2 should account for dynamic macropore connectivity and the effects of soil moisture on macropore flow, but more research is needed to determine experimentally the spatiotemporal variation of macropore flow in agricultural soils.Les stratégies d'intervention ciblées sur la prévention de l'eutrophisation des eaux de surface en milieu agricole devraient prendre en compte que relativement plus de phosphore chemine vers les drains souterrains par les macropores du sol qu'en cheminement matriciel. Afin de décrire les phénomènes de transport de phosphore aux drains, le modèle hydrologique SWAT (Soil and Water Assessment Tool) doit être en mesure de distinguer ces processus de transfert. La présente étude avait pour objectif d'évaluer la performance d'un nouvel algorithme séparant les écoulements matriciels et préférentiels, en mettant à profit des jeux de données existantes et suivant une démarche compatible avec l'approche de modélisation inhérente à SWAT. L'algorithme a d'abord profité d'une validation conceptuelle, hors du modèle SWAT, puis d'une évaluation suivant son intégration à une nouvelle version du modèle hydrologique, SWAT-QC2. La validation conceptuelle de l'algorithme a démontré que les flux matriciels épisodiques prédits augmentent avec les précipitations journalières, à la condition que le taux d'infiltration ait atteint un seuil limite, relativement moins élevé en sol argileux. Bien que l'algorithme n'ait pas amélioré la prédiction du débit total d'un petit bassin versant du Sud du Québec (30 km2), il a néanmoins amélioré la performance du modèle SWAT à répartir les écoulements de surface et souterrains. La comparaison des prédictions du modèle hydrologique avec les résultats de séparation des hydrogrammes à l'exutoire du même bassin versant suivant une méthode chimique témoigne d'une performance réaliste de SWAT-QC2 à prédire la répartition des flux souterrains préférentiels et matriciels. A l'instar de la validation conceptuelle de l'algorithme, les flux préférentiels prédits sont relativement plus importants en sol argileux qu'en texture plus grossière. En décrivant la proportion des écoulements souterrains qui emprunte la voie préférentielle, et qui contrôle potentiellement les transferts souterrains de P, l'algorithme d'écoulement en macropores constitue une assise pour le développement ultérieur de SWAT intégrant une description des transferts souterrains de phosphore vers les drains souterrains. Afin d'améliorer la performance de SWAT-QC2 à séparer les flux préférentiels et matriciels, les développements futurs du modèle hydrologique devraient prendre en compte la nature dynamique de la connectivité des macropores, de même que les effets de l'humidité du sol sur l'écoulement préférentiel. Cette démarche appelle cependant à une meilleure caractérisation expérimentale de la variabilité spatio-temporelle des flux préférentiels en sols agricoles.

Full textAbstract:
Although it has long been portrayed as the nation’s ‘moat defensive’, recent examinations of Anglo-French rivalry during the long eighteenth century have revealed that the English Channel was, in reality, a highly permeable and vulnerable maritime border territory. Within this context, the Channel Islands assumed a strategic and tactical significance which was vastly disproportionate to their physical size, population or resources; emerging as what Morieux terms ‘a lynchpin of control' over local shipping and trade. Although a great deal of research has been already undertaken – particularly in relation to the Channel Islands’ role as a base for commerce-raiding and intelligence gathering – much of this has covered the entire long eighteenth century. However, it was only during the Great French War that the British government embraced the military potential of the Channel Islands to the fullest; not only exploiting the inhabitants’ knowledge of the seas and intimacy with her ‘enemies’, but also transforming the archipelago into a chain of offshore fortresses. In addition, prior scholarship has often focused on individual aspects of the Channel Islands’ involvement in the Great French War; while local historians have tended to embrace the ‘Great Man’ approach, examining the period through the lens of the careers of local commanders. Consequently, this thesis seeks to provide a more complete picture of the Channel Islands’ role within Britain’s military and naval strategy; integrating an examination of local defence and security with several of already well-covered topics. Moreover, in light of the fact that existent scholarship has often centred upon ‘Great Men’, it is hoped that the thesis shall serve to better demonstrate the extent to which the celebrated achievements of Don, Doyle and D’Auvergne rested upon the efforts of a number of ‘unsung heroes’.

Full textAbstract:
Asian-Americans are the fastest growing ethnic minority group in the United States, followed by Hispanics. Little is known about their health state preferences or their health status. The purpose of this research was to determine whether a Chinese-American population has different preference values on four dimensions of health status than a general community sample in the United States. Also of interest was the self-reported health status of this sample of Chinese-Americans, using weights derived from Americans or Chinese-Americans to see whether the resulting index scores were significantly different. The question is whether Quality of Well-Being (QWB) weights derived from preferences of the American sample were appropriate for scoring QWBs for the Chinese-Americans. This research was conducted on 383 Chinese-Americans living in the San Gabriel Valley area, east of Los Angeles, California. A model of deliberate sampling for heterogeneity and a snowball sampling strategy were used for subjects' selection into the study. Three instruments (a weighting booklet, the Quality of Well-Being Scale, and a demographic battery), each having an English and a Chinese version, were used. Results indicate that the reliability and validity of the booklet rating and QWB Scale were high in the Chinese-American sample. The preference weights derived from the sample of Chinese-Americans were different from those derived from the community sample of Americans. Although the weights cannot be compared individually due to the lack of variance associated with them, of those 48 levels on the symptom/problems scale, 28 of the Chinese-American weights were lower than the American weights. For the 11 levels of the three functional scales, eight were higher than the American sample. The mean QWB scores calculated using Chinese-American weights were lower than those calculated using American weights. Therefore, QWB weights derived from preferences of the American sample were not appropriate for scoring QWBs for the Chinese-Americans.

Full textAbstract:
An original bilingual (Gaelic-English) collection of vocabulary, nomenclature and terminology relating to shinty and hurling, with reference to other stick and ball games is included as the first element. The sources consulted in Scotland, Ireland, Canada and Australia provide the first synthesis of material available about shinty in the nineteenth century across four Continents. Shinty is set in its historical context, examining the evidence, literary and oral, in both Gaelic and English, linking the game to other sports and cultures. A source-based approach is used to produce an analytical and innovative examination of the importance of shinty in its pre-regulated era, principally in terms of New York celebration. The game is examined in a specifically cultural context detailing how it changed during the nineteenth century with its fluctuating fortunes in rural and urban environments compared and contrasted over time. "Shinty in Glasgow" details the historical provenance of shinty in the Gaelic capital of the Highlands; "Shinty in England" details the precise nature of the game beyond Hadrian's Wall; "Shinty in the Americas" has as its focus shinty's influence as cultural anchor in Canada, and the apparent progenitor of ice hockey; "Shinty in Australia" breaks new ground, disproving the current mythology surrounding the game in Australia, examining the extent to which shinty survived as part of the cultural baggage taken by Scottish emigrants in the nineteenth century. Two chapters on the modern game analyse the effects of World Wars and economic/demographic change on the game and assess the links which existed with the Irish game of hurling at a number of levels. Revisionary conclusions are offered about the extent to which shinty was played as a game in the nineteenth century; how it was played across Scotland and an assessment made of the legitimacy of the game's traditional claim to be "Scotland's national game".

Full textAbstract:
Human activities are placing unprecedented pressure on natural ecosystems, threatening to push many species into extinction. In response to this, a call for a reduction in the current rate of biodiversity loss by 2010 was made and global biodiversity indicators were adopted to monitor progress. Perhaps the best known of these are the Red List Indices, which are based on temporal changes in extinction risk of species assessed for the International Union for Conservation of Nature (IUCN) Red List. In the case of plants, conservation assessments for globally-representative samples of species have been carried out mainly utilising comprehensive worldwide herbarium resources, and have shown that more than 1 in 5 plant species is threatened with extinction under IUCN Red List Criteria. The aim of this thesis was to provide the scientific bases for an automated procedure to re-assess plant species pan-tropically on a 5-year time frame in order to calculate the change in the IUCN Sampled Red List Index (SRLI) for Plants as a measure of global trends in plants extinction risk. This study has focused first on improving the method used for calculating species ranges using the available IUCN SRLI for Plants data and to develop a new measure of species range, the Extent of Suitable Habitat (ESH). The results show that this new calculation method is effective at reflecting a closer reality of plant distributions on the ground, and that such a simple method can be used to predict the current distribution of species globally. The species ESHs were then assessed through time against the degree of human impact using data from a global monitoring system for deforestation and from a future land use change scenario applied by the Co$ting Nature tool. On the basis that land cover change can be used as a proxy for local extinction risk and that a species’ ESH can be re-calculated to factor in the impact of land cover change (habitat loss), this thesis showed that a species’ ESH could be used for re-assessing the conservation status of plant species under IUCN Criterion B sub-criterion b(iii). This way, more dynamic, comparable and spatially-detailed Red List Index updates could be provided. To test the ESH range calculation this method was also compared with a widely accepted species distribution modelling approach and validated using new species occurrence points. Additionally, ESH derived species richness maps were produced for conservation prioritisation, validated using fieldwork data from previous studies and compared with existing species richness maps for plants.
