Full textAbstract:
During the period April 1994 and February 1996 as part of an investigation into the national Iinefishery, the east coast shore fishery and the recreational and commercial ski-boat fisheries were surveyed, at eight sites between Kei Mouth in the East and Stil Bay in the West. Roving creel, access point and aerial surveys were used. A questionnaire was developed for each sector to gather data on catch and effort, fisher demographics, economics, fisher attitudes towards, and knowledge of, the current management regulations and assess the efficacy of the fisheries inspectorate. During the access point survey the catch of 3273 fishers was inspected and 1556 interviews were conducted. Questionnaires were conducted on 118 recreational ski-boaters and the catch of 165 boats was inspected. 96 commercial skippers were interviewed and 230 had their catch inspected. Three aerial surveys of the entire area were conducted during which a total of 1067 shore fishers were counted giving a shore fisher density of 0.39 fishers.km⁻¹. The majority (99%) of participants in all sectors of the linefishery were male. The greatest number of participants were white, shore fishery 77% recreational ski-boat 98% commercial skiboat 89%, followed by coloured, asian and black people. To a large extent this reflects the income of various racial groups. Most fishers supported the current linefish management plan. However, when tested on their knowledge of the size limits, bag limits and closed seasons of their target species many shore fishers (59%) did not know them and a high proportion of fishers in all sectors had disobeyed at least one of the regulations (shore 50%, recreational ski-boat 70%, commercial ski-boat 56%). When compared to historical data the present catch per unit effort (CPUE) in all sectors has decreased. Most interviewees in the various sectors did not accept responsibility for the decline in CPUE, but attributed it to three principal reasons vis their perceived direct competitors, trawling and pollution. Analysis of the catch revealed that all sectors were multispecies fisheries, with each sector being characterised by a small number of target species. Catch composition differed significantly between the shore and ski-boat sectors, but there was significant overlap between the two skiboat sectors. Analysis of the catch in comparison to that reported to the National Marine Linefish System (NMLS) revealed that there was a substantial degree of under-reporting. There was little seasonal difference in effort in the shore fishery while the recreational ski-boat effort was highest in the summer and the commercial ski-boat effort was high in the winter. Effort in the shore and recreational ski-boat fisheries was concentrated over weekends while the commercial ski-boat effort was highest during weekdays. Total effort for the entire area was estimated at 903 186 (±1913) fisher days per annum in the shore fishery, 24 357 (±685) recreational ski-boat fisher days and 64 266 (±1686) commercial ski-boat fisher days. Expenditure and capital investment in the various sectors was calculated, as were earnings of the participants in the commercial ski-boat sector. The linefishery in the Eastern Cape was estimated to have a minimum capital investment in excess of R210 million and more than R32 million is spent annually on running costs. The commercial ski-boat fishery directly employed an estimated 3184 people. The economic implications of changes in CPUE for the commercial ski-boat fishery are considered, as are the benefits of a recreational angling licence. Management of the linefishery is discussed in relation to the findings of this study.

Full textAbstract:
This dissertation deals with the nature of the black middle-class assimilation in the South African suburban space, a space that was the sole preserve of the white middle-class during apartheid. It explores the relationship between these races as they come to meet in this space and what new identities are being formed. It also explores the relationship between both the black and white suburbanites and the urban poor who stay in an adjacent area to the suburb. The study uses the Beacon Bay area, which is constituted by one of East London’s most affluent suburbs and a poor township, Nompumelelo, to show how the emergent black middle-class has managed to enter this space in the post-apartheid era. Previous studies by Richard Ballard (2004) and Grant Saff (2001) have shown how the white middle-class has always been against any form of race or class mixing. Within the suburb, the new black suburbanites in Beacon Bay appear to have been welcomed but with conditions by their fellow white counterparts. The relationship between these two races does not stretch beyond meet and greets and it is only in the second generation black middle-class that you find better and non-superficial relations with fellow white suburbanites. In the older generation, the generation that experienced apartheid, the relationship between these two races has been that of tolerance and serious escape of contact unless when necessary. The children of both white and black families, though, have a far better relationship in school and in sport than their parents. This has created another area of contact for both these races and it bears potential for meaningful integration in the suburban space. Externally as it relates to relations between the black middle-class and the urban poor, the findings show that these new black suburbanites express a similar discomfort as the white suburbanites about the urban poor’s presence in the area. This shows that the evolution of the Beacon Bay suburb, with its deep-rooted discourse of white middle-class exclusivity, has not been entirely about hatred of the urban poor necessarily but about an identity ascription of what it means to live in a suburb. Despite these realities traditional ceremonies organised by the black middle-class in the suburbs and the church appear to be playing a role in creating relations between these suburbanites and the Nompumelelo residents. This is why we have decided to use the conceptualisation of the 18th century frontier zone as the borders of segregation within the suburb and between the suburban residents and those of the township can be crossed and re-crossed.

Full textAbstract:
Female mammals play a central role in determination of social structure and are thus central to understanding the overall fission-fusion grouping pattern characteristic of many delphinid societies. Focusing specifically on female-female relatedness and association patterns, I have analysed more than 17 years of group composition, behavioural data, and genetic information to investigate complex interactions between behavioural ecology and relatedness and to also examine the common social evolutionary theory, that variation in mammalian social systems is typically attributed to five main factors: inclusive fitness, predation pressure, sexual conflict and male harassment, inbreeding avoidance, and resource competition. Overall, I found that female bottlenose dolphin association patterns depend upon the interplay between matrilineal kinship, biparental relatedness and home range overlap, and that female bottlenose dolphins seem to adapt their social strategies to seasonal variation in levels of predation and male harassment. The presence of both high sexual conflict and bisexual philopatry lead me to investigate the extent of inbreeding avoidance. I found that more than 14% of the calves were most likely the product of mating between close relatives, and identified female fitness costs to inbreeding. We were able to show that the effect of inbreeding on females??? fitness occurs via two independent mechanisms: being inbred and having at least one inbred calf. Inbred calves are on average weaned later than non-inbred calves, and a female???s first calf has a higher probability to be an inbred than subsequent calves. Last, I examined whether sociality provides inclusive fitness to female bottlenose dolphins through an investigation of both the additive genetic and social variance components of female calving success using a pedigree-free animal model. I found that variance in calving success of female bottlenose dolphins is best explained by complex genetic and social interactions. Females with high calving success showed both high genetic and social merit; they not only have good genes but also prefer to associate with others of high fitness. This study reveals that both social and heritable genetic variance contribute to fitness trait variance in the wild.

Full textAbstract:
The Antarctic plays an important role in the global climate system. On the one hand, the Antarctic Ice Sheet is the largest freshwater reservoir on Earth. On the other hand, a major proportion of the global bottom-water formation takes place in Antarctic shelf regions, forcing the global thermohaline circulation.
The main goal of this dissertation is to provide new insights into the dynamics and stability of the EAIS during the Quaternary. Additionally, variations in the activity of bottom-water formation and their causes are investigated. The dissertation is a German contribution to the International Polar Year 2007/ 2008 and was funded by the ‘Deutsche Forschungsgesellschaft’ (DFG) within the scope of priority program 1158 ‘Antarctic research with comparative studies in Arctic ice regions’.
During RV Polarstern expedition ANT-XXIII/9, glaciomarine sediments were recovered from the Prydz Bay-Kerguelen region. Prydz Bay is a key region for the study of East EAIS dynamics, as 16% of the EAIS are drained through the Lambert Glacier into the bay. Thereby, the glacier transports sediment into Prydz Bay which is then further distributed by calving icebergs or by current transport. The scientific approach of this dissertation is the reconstruction of past glaciomarine environments to infer on the response of the Lambert Glacier-Amery Ice Shelf system to climate shifts during the Quaternary. To characterize the depositional setting, sedimentological methods are used and statistical analyses are applied. Mineralogical and (bio)geochemical methods provide a means to reconstruct sediment provenances and to provide evidence on changes in the primary production in the surface water column. Age-depth models were constructed based on palaeomagnetic and palaeointensity measurements, diatom stratigraphy and radiocarbon dating.
Sea-bed surface sediments in the investigation area show distinct variations in terms of their clay minerals and heavy-mineral assemblages. Considerable differences in the mineralogical composition of surface sediments are determined on the continental shelf. Clay minerals as well as heavy minerals provide useful parameters to differentiate between sediments which originated from erosion of crystalline rocks and sediments originating from Permo-Triassic deposits. Consequently, mineralogical parameters can be used to reconstruct the provenance of current-transported and ice-rafted material.
The investigated sediment cores cover the time intervals of the last 1.4 Ma (continental slope) and the last 12.8 cal. ka BP (MacRobertson shelf). The sediment deposits were mainly influenced by glacial and oceanographic processes and further by biological activity (continental shelf), meltwater input and possibly gravitational transport.
Sediments from the continental slope document two major deglacial events: the first deglaciation is associated with the mid-Pleistocene warming recognized around the Antarctic. In Prydz Bay, the Lambert Glacier-Amery Ice Shelf retreated far to the south and high biogenic productivity commenced or biogenic remains were better preserved due to increased sedimentation rates. Thereafter, stable glacial conditions continued until 400 - 500 ka BP. Calving of icebergs was restricted to the western part of the Lambert Glacier. The deeper bathymetry in this area allows for floating ice shelf even during times of decreased sea-level. Between 400 - 500 ka BP and the last interglacial (marine isotope stage 5) the glacier was more dynamic. During or shortly after the last interglacial the LAIS retreated again due to sea-level rise of 6 - 9 m. Both deglacial events correlate with a reduction in the thickness of ice masses in the Prince Charles Mountains. It indicates that a disintegration of the Amery Ice Shelf possibly led to increased drainage of ice masses from the Prydz Bay hinterland. A new end-member modelling algorithm was successfully applied on sediments from the MacRobertson shelf used to unmix the sand grain size fractions sorted by current activity and ice transport, respectively. Ice retreat on MacRobertson Shelf commenced 12.8 cal. ka BP and ended around 5.5 cal. ka BP. During the Holocene, strong fluctuations of the bottomwater activity were observed, probably related to variations of sea-ice formation in the Cape Darnley polynya. Increased activity of bottom-water flow was reconstructed at transitions from warm to cool conditions, whereas bottom-water activity receded during the mid- Holocene climate optimum.
It can be concluded that the Lambert Glacier-Amery Ice Shelf system was relatively stable in terms of climate variations during the Quaternary. In contrast, bottom-water formation due to polynya activity was very sensitive to changes in atmospheric forcing and should gain more attention in future research.Die Antarktis spielt im globalen Umweltsystem eine tragende Rolle. Mit ihrem mächtigen Eispanzer ist sie nicht nur der größte Süsswasserspeicher auf der Erde, in ihren Schelfregionen wird auch ein Großteil der globalen Bodenwassermassen gebildet, welche die globale thermohaline Zirkulation antreiben. Hauptziel dieser Arbeit, welche einen deutschen Beitrag zum Internationalen Polarjahr 2007/ 2008 liefert, war es, neue Erkenntnisse hinsichtlich der Stabilität des Ostantarktischen Eisschildes während des Quartärs zu liefern. Weiterhin sollten Aussagen über Variationen in der Bildung von Antarktischem Bodenwasser und deren Ursachen getroffen werden. Dazu wurde im Rahmen der ‚Polarstern‘ Expedition ANT-XXIII/9 eine Beprobung glaziomariner Sedimente zwischen Prydz Bucht und Kerguelen Plateau durchgeführt. Diese Region eignet sich zur Untersuchung der Ostantarktischen Eisdynamik besonders gut, da hier der Lambert Gletscher, etwa 16% des Ostantarktischen Eispanzers drainiert. Er transportiert dabei Sediment nach Norden, das schließlich die Prydz Bucht erreicht und durch direkten Transport über kalbende Eisberge oder durch Umlagerung und Verteilung mithilfe von Meeresströmungen weiter verfrachtet wird. Der wissenschaftliche Ansatz dieser Arbeit besteht darin, über die Verteilung dieser Sedimente in Raum und Zeit, d.h. über Variationen des glaziomarinen Paläoregimes, die Reaktion des Lambert Gletschers und des vorgelagerten Amery Schelfeises auf Klimaschwankungen während des Quartärs zu rekonstruieren. Dabei werden sowohl sedimentologische Methoden unter Einbeziehung neuer statistischer Möglichkeiten angewandt, um Sedimentationsprozesse zu charakterisieren, als auch mineralogische und (bio)geochemische Parameter verwendet, um Aussagen über die Herkunft der Sedimente und Änderungen in der Produktivität im Oberflächenwasser treffen zu können. Die Altersbestimmung der Sedimentkerne erfolgte mittels Paläomagnetik, Paläointensitäten, Biostratigraphie und Radiokarbondatierungen. Die Oberflächensedimente im Untersuchungsgebiet zeigen deutliche Unterschiede sowohl hinsichtlich ihrer Tonmineral- als auch Schwermineralzusammensetzung. Beide mineralogischen Parameter zeigen die größten Differerenzen auf dem Schelf. Dort lassen sich deutlich Sedimente der Prydz Bucht von Sedimenten des MacRobertson Shelfes differenzieren. Sie stellen daher ein gutes Hilfsmittel dar, um sowohl die Herkunft von eis- als auch strömungstransportiertem Material zu rekonstruieren. Die untersuchten Sedimentkerne decken den Zeitraum der letzten 1,4 Millionen Jahre (Kontinentalhang) bzw. der letzten 12,8 tausend kal. Jahre v. H. ab (MacRobertson Schelf). Die abgelagerten Sedimente wurden i. W. durch glaziale und ozeanographische Einflüsse geprägt, aber auch durch Bioproduktion (Schelf) bzw. durch Schmelzwassereinträge und möglicherweise gravitative Prozesse (Kontinentalhang). In den Sedimenten des Kontinentalhangs sind zwei starke Enteisungsereignisse überliefert: Das erste Ereignis steht mit dem mittelpleistozänen Klimaoptimum in Verbindung, das auch in anderen antarktischen Regionen nachgewiesen wurde. Es führte in der Prydz Bucht zu einem weitreichenden Rückzug des Lambert Gletscher-Amery Schelfeises (LAIS) und gleichzeitig zu einer hohen Primärproduktion. Danach herrschten bis etwa 400 - 500 tausend Jahre v. H. stabile glaziale Bedingungen. Kalbung von Eisbergen war wahrscheinlich auf den westlichen Teil des Lambert Gletschers begrenzt, wo eine tiefere Bathymetrie auch bei niedrigerem globalen Meeresspiegel noch Aufschwimmen des Gletschereises erlaubt. Zwischen 400 - 500 tausend Jahren v. H. und vermutlich dem letzten Interglazial wurde der Gletscher schließlich wieder dynamischer, um mit oder kurz nach dem letzten Interglazial (Meeresspiegel etwa 6 - 9 m höher) eine weitere Phase deutlichen Rückzuges zu durchlaufen. Beide Ereignisse lassen sich mit Phasen der Eisreduktion in den Prinz Charles Bergen korrelieren, d.h. der Rückzug des Lambert Gletschers hatte möglicherweise ein erhöhtes Nachfließen von Eismassen aus dem Hinterland zur Folge. An den Sedimenten des Schelfkernes wurde ein neu entwickeltes Verfahren der Endmember-Modellierung erfolgreich getestet. Der Eisrückzug auf dem MacRobertson Schelf begann etwa 12,8 tausend kal. Jahre v. H. und war gegen 5,5 tausend kal. Jahre v. H. abgeschlossen. Während des Holozäns kam es zu starken Schwankungen in der Bodenwasseraktivität, die höchst wahrscheinlich mit der Neubildungsrate von Meereis in der Kap Darnley Polynia in Zusammenhang stehen. Besonders auffallend war eine erhöhte Bodenwasseraktivität am Übergang von Warm- zu Kaltphasen bzw. ihr extremer Rückgang während des Mittel-Holozänen Klimaoptimums. Insgesamt zeigen die Ergebnisse der Arbeit, dass sich das LAIS während des Quartärs relativ stabil gegenüber Klimaveränderungen verhalten hat. Die Bodenwasserproduktion in Polynien dagegen reagierte sehr empfindlich auf relative geringe atmosphärische Veränderungen und bedarf in Zukunft verstärkter Aufmerksamkeit.

Over the past thirteen years the United States has used military force against three different Muslim-majority nations. These conflicts have lead to the deaths of many Muslims, including many innocent civilians. Meanwhile, American Muslims have become conflicted about their identities as Muslims and Americans. However, this does not mean that they have become a fifth column within America. What it does mean is that they have felt anguish regarding the torment of their religious brethren, while at the same time retaining their American identity. Post-9/11, Muslim American groups have acknowledged their place in the racial ordering of America. Muslim Americans understand that they are second rate citizens within their own country.

Full textAbstract:
The increasing world population and with it the increased pressure on food production are likely to challenge the availability of quality fresh water resources in the near future. To compound the looming water crisis, caused by an increased demand for water available for agricultural production, the quality of our fresh water resources is also likely to suffer from the consequences of increased population pressure, i.e. urbanization of land and growth of industries, and food production, i.e. agricultural use of land. Moreton Bay, South East Queensland, Australia, is listed under the United Nations Convention on Wetlands and is also a declared Marine Park. The Moreton Bay area, however, is already one of the five fastest growing urban areas in the developed world. Prognoses about future population growth and urban and industrial development in the area, have hence given rise to growing concerns about the future water quality in this international environmentally important area. Therefore the aim of the current study was to investigate the fate of nutrients in freshwater streams in the Moreton Bay area in order to gain a better understanding of nutrient pathways in aquatic systems and assist in refining the National Water Quality Management Strategy to provide better management of our waterways. To achieve this, the effects of land use on water quality were determined at 22 study sites in the Brisbane River Catchment. Within the catchment five main types of land use were identified, including urban, rural residential, cropping, grazing and mixed types of land use. Water quality was sampled during three seasons: the pre-wet (October - November), wet (December - March) and dry (April - August) season. Nitrogen and phosphorus concentrations in ambient stream water varied significantly spatially, i.e. types of land use, and temporally, i.e. seasons. At some sites, during certain times of the year, nutrient concentrations were found to exceed the range recommended by the Australian Water Quality guidelines. Nutrient concentrations were particular high in urban areas, especially during the dry season. It was also found that the 15N signatures in aquatic plants, i.e epipelic algae, correlated strongly with in-stream nitrogen concentrations. The large variability of in-stream nutrient concentrations, and the related changes in nitrogen isotopic signatures in aquatic plants, made it obvious to suggest that changes in land use may significantly impact on water quality in the catchment. Other changes in land use, for example riparian vegetation clearing, are also commonly observed in areas under urban, industry and/or agricultural growth pressure. This is of particular concern, given riparian vegetation is important not only in controlling nutrient and other organic matter input into streams, but also in regulating light levels for in-stream primary production. Previously riparian zones have been shown to be a prime source of carbon and energy for aquatic food webs in some studies, whereas other studies suggested the main driver of food webs is in-stream primary production. The current study used stable isotope analysis track carbon and nitrogen pathways through aquatic systems and determine the primary source of carbon and energy in aquatic food webs. Despite large spatial and temporal variability of 13C, aquatic consumers were closely tracking the carbon isotope signatures of plants and it was suggested that epilithic and epipelic algae are the main contributors to the carbon and energy budget of aquatic consumers.In realizing this importance of algae in aquatic systems, the next step in this study was to examine the relative importance of light and nutrient availability to periphyton and the effects of changes of these variables on plant biomass and primary production. In an in-situ experiment the levels of light and nutrients available to periphyton, were altered. Although nutrients and light may have colimited standing crop of periphyton, other variables were clearly limited by light. Parallel to this experiment on periphyton, the nutrient availability to Vallisneria spp. was experimentally altered to investigate the effects of changes in nutrient availability and nutrient limitation on other aquatic plants. The biomass of this submerged macrophyte increased three-fold in nitrogen and phosphorus sufficient areas over nutrient limited treatments. The physiological response, i.e. changes in concentrations of amino acids, of periphyton to changes in environmental conditions was also investigated on a large scale, i.e. spatial and temporal variability of amino acids, and a local scale, i.e. amino acid changes in artificially altered light and nutrient availability. This response was of particular interest in this study, as it was previously shown that physiological changes in plants impact on the quality of plants as food for consumers. The physiological changes in aquatic plants could thus provide an important link between nutrient input into streams (e.g. from terrestrial sources), impacts on aquatic plants (e.g.. nutrient uptake and physiological responses in plants) and effects on aquatic consumers (e.g. changes in food quality of plants and therefore impacts on biomass, growth and overall health of aquatic consumers).

Full textAbstract:
Western value systems and ways of knowing the world are in need of serious critique, especially in terms of colonialism and capitalism. These systems, many argue are fundamentally unjust and unsustainable while also working toinvalidate and erase alternative, indigenous ways of knowing. We need to work towards decolonization by both challenging these dominant Western systems, and exploring and supporting alternatives. That the primary intent of this thesis, which aims to engage and compare indigenous and Western worldviews using two specific case studies of land management. The first, Ngāti Whātua Ōrākei, represents an indigenous Māori approach in a New Zealand context, while the East Bay Regional Park District represents a ‘conventional’ Western approach in a US context. The analysis of these groups was based primarily on management plans and other assorted documents, as well as personal experience working with Ngāti Whātua Ōrākei in particular. The structure and practice of each group were explored separately, and connected with the systems and values of their respective cultural contexts. Comparisons were then made exploring differences in community participation, ways of knowing, and systems of values and belief. The District, while showing significant concern for the environment, was still engaged in limiting and harmful colonial practice. In contrast the practice of Ngāti Whātua Ōrākei, with its local focus, community engagement, and deep relation with the land, is a worthy source of inspiration in moving towards a world that is more safe, just, and sustainable.

This thesis describes the formation of the East Bay Green Corridor (EBGC), a multi-city partnership for green investment in California, and how it failed to create stable, living wage economic opportunities for those with high employment barriers between 2007 and 2012. By analyzing semi-structured interviews with key informants and green economic development data at regional and urban levels, it provides insight on how EBGC cities tried to influence the distribution of "green-collar" jobs and businesses through various policy experiments. This study largely attributes the conclusion to the fact that EBGC did not have the capacity to be effective as an organization, which ultimately led to its dissolution in 2013 into an unfunded volunteer project. Using regional analysis, it also finds that the highest years of green employment growth (2007-08) in the California East Bay preceded the existence of EBGC activities. Furthermore, it calls into question the long-term economic impacts of EBGC activities by showing that the Great Recession slowed employment growth rates in green sectors more than it did the employment growth rates in non-green sectors. While this thesis does not critique the concept or possibility of a green-collar economy as other reports have, it suggests a few ways that policymakers interested in green-collar economic development can be grounded and strategic about their approaches to regional partnership and poverty alleviation to realize the desired returns on this type of economic development investment.

Saldanha Bay harbour principally services loose- and liquid-bulk carriers and the Ngqura harbour mainly services container ships. The long wave actions when severe cause moorings to be broken, ships to leave the quay and loading to stop. This research has confirmed that the sea surface is a multifractal structure characterised by many singularities ranging from highly irregular or rough features to smooth or calm features. Any wave train is comprised of the full range of these features to various degrees and in varying percentages of occupancy. Notwithstanding this problem, relatively little is known about them in the South African context due to the fact that they cannot be visually detected and specialised, sophisticated equipment is required to physically measure them. The country is currently planning the development of a new port and the expansion of others for larger ships. Under these circumstances this research is seen to be appropriate from the point of view of obtaining a new method for the characterisation of these hazardous wave conditions. The objective of the research was achieved. This was to identify a set of fractal dimensions that describe the surface geometry of a hazardous bound infragravity wave sea state. In order to achieve the objective, a set of fractal dimensions was firstly determined from video imagery of an open water wave field, by analysing a set of single point time series data derived from the imagery. This has been done in order to be able to visually compare the derived set of fractal dimensions with video imagery of the sea surface that they represent. It also has the advantage of proving that fractal methods of analysis are applicable for the study of sea surface single point time series data. Secondly, periods when long wave action occurs at both Saldanha Bay and Ngqura harbours were identified by the presence of their actions in the harbours. Thirdly, single point time series data recorded by the Council for Scientific and Industrial Research (CSIR) were obtained during the identified periods as well as two days before these times and fractal sets of dimensions for the periods were determined. This was achieved by means of the following methods of analysis: ● The rescaled range (R/S) method, ● The Multifractal Detrended Fluctuation Analysis (MDFA) method, ● The Power Spectral Density (PSD) method in both the Fourier and the wavelet domains, and ● The Wavelet Transform method. Fourthly, the fractal data sets from each harbour were compared to confirm that the sets of dimensions for the hazardous sea state are clearly different from those of the non-hazardous sea state and can be used to describe the condition. Finally, the fractal sets of dimensions for hazardous sea states at both harbours were compared to identify any variances between them. During the research it was found that a hazardous sea state could be profiled for identification purposes and for complementing the currently determined significant wave height and peak period details by means of fractal indices. These indices were identified by comparison with a similar set of indices for nonhazardous sea states at the same location, as part of a ‘calibration’ process and clearly identified shifts in the Holder exponents of the sea states enabled the unambiguous identification of the hazardous condition. Having completed the research and analysis work, the author has identified other areas of coastal engineering, besides the identification of hazardous bound infragravity wave sea states, where a study of multifractal geometry could be applied advantageously.
AFRIKAANSE OPSOMMING: Alle hawens langs Suid Afrika se kuslyn is tot ‘n meerdere of mindere mate onderworpe aan gebonde infragravitasie golf aksie. Hierdie probleem is egter veral straf by die hawens van Saldanhabaai aan die weskus en Ngqura, aan die suidooskus. Saldanhabaai voorsien dienste hoofsaaklik aan massa draers van los stowwe en vloeistof, terwyl Ngqura hoofsaaklik houerskepe bedien. Die lang golf aksies veroorsaak dat ankertoue breek en die skepe die kaai verlaat, sodat laai van die skepe tot stilstand kom. In die loop van hierdie navorsing is gevind dat die seevlak ‘n multifraktale struktuur is, met singulariteitseienskappe wat wissel van hoogs onreëlmatig of rowwe eienskappe tot gladde, reëlmatige eienskappe. Enige golfreeks behels die volle omvang van hierdie eienskappe in verskillende grade en wisselende teenwoordigheids persentasies. Die navorsing is gefokus op die geometrie van gebonde infragravitasie golfaksie seetoestande, wat oral langs die Suid Afrikaanse kuslyn voorkom, en in twee hawens ‘n beduidende bedreiging vir vasgemaakte skepe is. Ondanks die probleem, is min bekend oor hierdie toestande in Suid Afrikaanse konteks, omdat hulle nie visueel bespeur kan word nie en spesiale gesofistikeerde gereedskap nodig is om hulle fisies te kan meet. Daar word tans beplan om ‘n nuwe hawe te ontwikkel, wat hierdie navorsing veral gepas maak, met die doel om ‘n meer volledige beskrywing van hierdie bedreigende golftoestande te weeg te bring. Die doel van die navorsing is om ‘n stel fraktale dimensies te identifiseer wat die oppervlakgeometrie van ‘n bedreigende gebonde infragravitasie golf-seetoestand omskryf. Hierdie dimensies kan dan gebruik word om ‘n indentifiserende profiel van die seetoestand te teken om die inligting tans beskikbaar oor beduidende golfhoogte en piektye, aan te vul. Om hierdie doel te bereik is ‘n stel fraktale dimensies eerstens bepaal deur middel van videobeelding van ‘n oopwater golfveld. ‘n Stel enkelpunt tydserie data, afgelei van die beelding, word dan ge-analiseer. Dit het visuele vergelyking tussen die afgeleide stel fraktale dimensies en die videobeelding van die seevlak wat dit verteenwoordig het, moontlik gemaak. ‘n Verdere voordeel is dat dit bewys het dat fraktale analisemetodes toepaslik is vir die bestudering van seevlak enkelpunt tydreeks data. Tweedens is die tye wanneer lang golfaksie teenwoordig was in die hawens by Saldanha en Ngqura, vasgestel deur die uitwerking daarvan in die hawens. Derdens is enkelpunt tydreeks data wat deur die WNNR aangeteken is vir die vasgestelde tydperke, sowel as twee dae voor elke tydperk, verkry en is fraktale dimensiestelle vir elke tydperk vasgestel. Vierdens is die fraktale datastelle van albei die hawens vergelyk om te bevestig dat die stelle dimensies vir bedreigende seetoestande duidelik verskil van die vir niebedreigende toestande, en dus geskik is om die seetoestand te beskryf. Ten slotte is die fraktale dimensiestelle vir bedreigende seetoestande in die twee hawens vergelyk om enige verskille tussen hulle te bepaal. Na voltooiing van die navorsing en analise is ander gebiede van kusingenieurswese behalwe die bepaling van bedreigende gebonde infragravitasie golf seetoestande, identifiseer waar multifraktale geometrie ook tot voordeel aangewend kan word.

Abstract
This thesis examines the Mid-Pliocene climatic extreme ca. three million years ago (Ma) which was the latest longtime warm period. It is an important topic because the climate back then was warmer compared with the present. The bipolar regions are studied because they represent the largest areas that control the global climate. This study is based on clay mineral research that may significantly improve our knowledge of the Mid-Pliocene climate when combined with other palaeoenvironmental data. The paleoclimatological objectives of this study were: 1) to investigate how clay minerals reflect the Mid-Pliocene Global Warmth event, 2) to study ice sheet development at high latitudes, especially in East-Antarctica, and the history of ice rafting and sea ice, especially in the Arctic Ocean.
This thesis deals with the clay mineral distribution and compositional analysis of the Pliocene-aged marine sediment sequences provided by the Ocean Drilling Program (ODP). The first studied site, Site 1165, is located at the continental rise of Prydz Bay, East Antarctica, and the second studied site, Site 911, is located at the Yermak Plateau, north of Svalbard, in the Arctic Ocean.
The Pliocene smectite clay minerals at Site 1165 were mainly derived from Antarctic continental sources and transported to the site primarly by bottom currents related to warm events during the last 5 Ma. The evidence obtained in this study shows that the East Antarctic ice sheet may have been a dynamic ice sheet during the past 5 Ma, especially during the Mid-Pliocene. The results from the Mid-Pliocene possibly suggest a general warming trend.
Based on the composition of the heavy minerals and clay minerals, at Site 911, the Pliocene smectite clay minerals were mainly transported within sea ice by the Siberian branch of the Transpolar Drift. The results indicate a warming trend at approximately 3 Ma after which they indicate a shift back to glacial conditions. Based on this study, the Mid-Pliocene Global Warmth can be observed in both the Arctic and Antarctic regions.

L'objectif principal de cette thèse est de restituer l'évolution passée des moussons asiatiques au cours du Quaternaire et d’en évaluer leurs impacts sur l’érosion continentale et les transferts sédimentaires terre-mer, à partir de l’étude de carottes marines collectées dans la Baie du Bengale, l'ouest de la mer des Philippines et la mer d'Arabie. La stratégie scientifique mise en œuvre implique des analyses minéralogiques (argiles), sédimentologiques (granulométrie laser) et géochimiques (⁸⁷Sr/⁸⁶Sr et εNd) afin de restituer les zones sources sédimentaires, les conditions d’érosion et de transfert sédimentaires à l’océan. Les analyses de la concentration en élément des terres rares et des valeurs de l’εNd ont également été faites sur des échantillons d’eau de mer et de foraminifères collectés dans la Baie du Bengale afin de contraindre l’utilisation de ce traceur dans un contexte de très forts changements saisonniers de débit des fleuves Himalayens. Cette stratégie nous a permis, entre autre, de restituer les précipitations de mousson du domaine ouest tropical Pacific au cours du Quaternaire et d’établir un lien avec l’évolution à long terme de la dynamique de circulation méridienne de type ENSO. Nous avons également apporté de nouvelles contraintes sur l’utilisation du traceur εNd dans les foraminifères de la Baie du Bengale en vue d’en restituer la dynamique passée de l’érosion himalayenneThe main objective of this PhD study is to reconstruct the evolution of the Asian monsoons during the Quaternary and their impacts on the continental erosion and sedimentary transfers from land to sea by the investigation of sediments cores collected in the Northern Bay of Bengal, the western Philippines Sea and the Arabian Sea. The implemented scientific strategy involves mineralogical (clay size fraction), sedimentological (grain-size laser) and geochemical (⁸⁷Sr/⁸⁶Sr and εNd) analyses in order to establish sedimentary sources, conditions of erosion and transfer of sediments to the Ocean. The analyses of the concentration of Rare Earth Elements (REE) and εNd were also made on seawater and foraminifera samples to better constrain the εNd as a proxy of weathering in a context of strong seasonal variations of sediment discharges by Himalayan rivers. Clay mineralogy and laser grain-size analyses have been conducted on sediments from core MD06-3050 collected on the Benham Rise (Philippines Sea). Siliciclastic grain-size results indicate variations of the relative proportion of three grain-size sub-populations corresponding to eolian dusts (EM2 about 9-11 μm) and Luzon rivers inputs (EM1 about 2-5 μm and EM3 about 19-25 μm). The long-term evolutions of the EM1/EM2 and smectite/(illite+chlorite) ratios permit to reconstruct variations of the contribution of detrital material deriving from the volcanic arc of Luzon and rainfall intensity of this tropical region. At long time scale, periods of intensification of monsoon rainfall on Luzon are associated to a reduction of precipitation on central China. These periods are also associated to an increase of the zonal gradient of sea surface temperatures on the equatorial Pacific Ocean suggesting a strengthening of El Niña conditions. These results highlight for the first time a strong role of the dynamics of the meridian circulation of ENSO on the long-term changes of rainfall of the tropical western Pacific during the Quaternary. In the Arabian Sea, clay mineralogy, siliciclastic grain-size, ⁸⁷Sr/⁸⁶Sr ratio and εNd were analysed on Quaternary sediments of the IODP site U1457. Our results suggest a change in the relative proportions of sediments from the Deccan Trapps (smectite) and the Indus river (mainly illite and chlorite). Variability of sedimentary sources and sediment transport (turbidites activity) to the Indus Fan have been reconstructed and attributed to monsoon rainfall and the sea level variations. The concentrations of REE combined with εNd were analysed on seawater samples collected in June 2012 along a North-South cross section in the Bay of Bengal. We highlighted from normalized REE patterns that the contributions of dissolved REE from the Ganges-Brahmaputra river system was the main source of the dissolved REE of surface waters of the Bay of Bengal, whereas the desorption of lithogenic particles dominate the dissolved REE of the intermediate and deep waters masses. We then revalued the residence time of the dissolved REE in the Bay of Bengal. A comparison of εNd, obtained just before the increase of the Ganges-Brahmaputra river discharge inferred by Indian monsoon rainfall, with the results obtained by Singh and al. (2012) for seawater samples collected after the peak of river discharge, allowed us to highlight for the first time a seasonal variability of seawater εNd of the Bay of Bengal. εNd have been analysed on planktonic foraminiferas of core MD77-176 located at 1375 m water depth to reconstruct for the first time the seawater εNd record of the intermediate waters masses of northern Bay of Bengal for the last 27 kyr. This new seawater εNd record of the Northern Bay of Bengal give us new constrain for this proxy already used to reconstruct past changes of the Himalayan weathering

Full textAbstract:
Le Golfe du Bengale (GdB), dans l'océan indien Nord, est sous l'influence d'intenses vents de mousson, qui se renversent saisonnièrement. Les fortes pluies et les apports fluviaux associés à la mousson de Sud-Ouest font du GdB l'une des régions les moins salées des océans tropicaux. La forte stratification haline proche de la surface qui en découle contribue à limiter le mélange vertical, ce qui maintient des températures de surface élevées et favorise la convection atmosphérique et les pluies. Cette stratification en sel a ainsi des implications profondes sur les échanges air-mer et sur le climat des pays riverains. L'objectif de ma thèse est d'améliorer la description de la variabilité de la salinité de surface (SSS) du GdB, et de comprendre ses mécanismes aux échelles de temps saisonnières à interannuelles. Les climatologies existantes ont permis de mettre en évidence un cycle saisonnier marqué de la SSS, avec un dessalement intense de la partie Nord du bassin pendant l'automne, suivi par une expansion de ces eaux dessalées le long du bord Ouest du bassin. Cette langue dessalée s'érode finalement pendant l'hiver, pour revenir à son extension minimale au printemps. Cependant, la rareté des observations in-situ de SSS ne permet d'observer les fluctuations interannuelles autour de ce cycle saisonnier que de manière parcellaire dans le GdB. Le développement récent de la télédétection spatiale de la SSS (missions SMOS et AQUARIUS) a ouvert de nouvelles opportunités à cet égard. Cette technologie reste toutefois délicate dans le cas d'un bassin de petite taille tel que le GdB, du fait des contaminations éventuelles du signal de SSS par les interférences radio et par les sources d'origine continentale. Une validation systématique des produits satellites par comparaison à un jeu de données in-situ exhaustif montre qu'Aquarius capture de façon réaliste les évolutions saisonnières et interannuelles de la SSS partout dans le GdB. A l'inverse, SMOS ne parvient pas à restituer une salinité meilleure que les climatologies existantesLocated in the Northern Indian Ocean, the Bay of Bengal (BoB) is forced by intense seasonally reversing monsoon winds. Heavy rainfall and strong river runoffs associated with the southwest monsoon makes the bay one of the freshest regions in the tropical ocean. This surface fresh water flux induces strong near surface salinity stratification, which reduces vertical mixing and maintains high sea surface temperatures and deep atmospheric convection and rainfall. This intense near surface haline stratification has therefore profound implications on the air-sea exchanges, and on the climate of the neighboring countries. The goal of my thesis is to improve the description of the Sea surface salinity (SSS) variability in the BoB and to understand the oceanic and atmospheric processes driving this variability at seasonal and interannual timescales. Existing climatologies reveal a marked seasonal cycle of SSS with an intense freshening of the northern part of the basin during fall that subsequently spreads along the western boundary. This fresh pool finally erodes during winter, to reach its minimal extent in spring. The paucity of in-situ SSS observations however prevented to monitor the interannual fluctuations around this seasonal picture with a good spatial coverage. The recent development of SSS remote-sensing capabilities (with SMOS and AQUARIUS satellites) may help with that regard. However this is particularly challenging for a small semi-enclosed basin such as the Bay of Bengal, because of the potential contamination of the SSS signal by radio frequency interferences and land effects in the near coastal environment. A thorough validation of these satellite products to an exhaustive gridded in-situ dataset shows that Aquarius reasonably captures the large-scale observed seasonal and interannual SSS evolution everywhere in the BoB while SMOS does not perform better than existing climatologies, advocating for improvements of its SSS retrieval algorithm there

Full textAbstract:
La présente étude traite de la contamination par les hydrocarbures, des sédiments superficiels de différentes stations réparties sur deux sites : la baie de Skikda (située en Méditerranée) et l'oued Saf-Saf (dans sa partie aval) qui se jette dans cette baie. Cette contamination a été étudiée des points de vue répartition géographique, origine et nature des hydrocarbures extraits. Les teneurs en hydrocarbures trouvées sont légèrement plus élevées dans le site oued Saf-Saf (278 mg.kg-1sed. sec), que dans le site mer (200 mg.kg-1sed. sec).Comparativement à d'autres études effectuées en mer Méditerranée, nos résultats témoignent d'un niveau moyen de contamination. L'identification des principales origines des hydrocarbures présents dans les sédiments des deux sites, a été effectuée en utilisant plusieurs indices relatifs aux hydrocarbures saturés et aux hydrocarbures aromatiques polycycliques.Les valeurs de ces indices ont permis de mettre en évidence plusieurs origines pour les hydrocarbures aussi bien dans le site oued Saf-Saf, que dans le de la baie de Skikda (origines biogènes naturelles terrestre et/ou marine, origines pyrolytiques naturelle ou pétrolière et origines pétrolières). Une étude statistique a fait l'objet d'une seconde partie de ce travail, à l'aide d'une série d'analyses et de tests univariés (ANOVA, Tukey et Dunnett appliqués aux périodes, puis aux stations pour chacune des 5 caractéristiques étudiées), bivariés (étude des corrélations) et multivariés (MANOVA, ACP et analyse hiérarchique). Ces tests ont été appliqués aux données des deux sites d'études et ont permis de confirmer les résultats obtenus dans la première partie du travailThe present study treats with the contamination by hydrocarbons, with superficial sediments of various stations repartee on two sites : the bay of Skikda (situated in the Mediterranean Sea) and the Saf-Saf oued (in its part downstream) with flows into this bay.This contamiation was studied by point of view geographical distribution, origin and nature of hydrocarbons extracts. The contents in found hydrocarbons are slightly more raised in the Saf-Saf oued (278 mg.kg-1sed. dry), that in the site sea (200 mg.kg-1 sed. dry). Compared with other studies made in the Mediterranean Sea, our results testify of an average level of contamination. The identification of the main origins of hydrocarbons presents in sediments of both sites, was made by using several indications relative to hydrocarbons saturated and in aromatic polycyclic hydrocarbons. The values of these indications allowd to highlight several origins for hydrocarbons as well in the Saf-Saf oued, as in Skikda bay (originate biogenic natural terristerial and/or marine, originate natural or oil pyrolytic and oil origins). A statistical study made the object of a second part of this work, by means of series of analysisesand of one-various tests (ANOVA, Tukey and Dunnett applied to periods, then to the stations for each of 5 characteristics), two-various (study of the correlations) and several-various (MANOVA, ACP and hierarchical analysis). These tests were applied to the data of both sites of studies and allowed to confirm the results obtained in the first part of the work

Full textAbstract:
As a result of development pressures and water resource struggles, once rural, spatially segregated coastal commercial fishing villages along the U.S. portion of the Gulf of Mexico are increasingly tourist frontiers for elites and the emergent businesses that cater to them. Over the course of the twentieth century, water events, from coastal land loss to hurricane destruction to natural disaster, have fast-tracked development projects that have allowed for the expansion of the tourism sector, and relaxed policies to encourage bold new economic development initiatives that often put poor coastal communities and their environment in jeopardy. This outcome is not universal across the northern Gulf Coast, but contingent on a number of local factors overlooked in the literature on coastal tourism and water policy development. This paper investigates the local nuances that have emerged as responses to global and regional development pressures by focusing on the ways in which local values and policy decisions have influenced the spread of coastal urbanization. An intensive analysis will examine the layered effects of changing land-use patterns and tourism growth pressures on three at-risk coastal communities in Louisiana, Mississippi and Florida, in the United States. This paper will test the hypothesis that coastal communities affected by a similar set of development pressures respond to these forces in different ways, depending on complex local and regional variabilities. The paper’s focus is centered on Northern Gulf Coast tourism growth patterns from post-World War II through 2018, and employs a mixed method, multiple-sited case-study design.

Full textAbstract:
This thesis examines the behaviour of two new models exhibiting topological solitons. This analysis is predominantly numerical, but a limited collective coordinate approach is attempted where appropriate. In chapter 1 we review the field of solitons. In particular the nature of topological solitons and their associated mathematical formalism are explained. A number of models admitting solitons are defined. In chapter 2 we look at the numerical methods necessary to solve the time evolution of topological solitons in the S(^2) sigma model and the baby Skyrme model. We also examine methods for finding static solutions of the equations of motion of such models. In chapter 3 we define the RP(^2) sigma and baby Skyrme models. We examine the behaviour of these models and find them to be identical to their (S^2) counterparts for most field configurations. The topological reason for this is explained. The existence of a topological object called a defect is noted and the behaviour of solitons in the presence of a defect is examined. A collective coordinate approach is used to examine the behaviour of solitons in the presence of a defect. In chapter 4 the easy plane baby Skyrme model is defined. An ansatz for the static skyrmions is proposed and its energy found to be accurate to 1.2% for the 1-skyrmion and about 0.5% for 2 to 4-skyrmions. These skyrmions are composed of two quasi- independent soliton like objects which we name "half lumps". These objects may not exist alone. The scattering properties of these objects are examined numerically. The behaviour of these scattering processes are explained in terms of the fields and potential energy of their intermediate states in the simulation. In chapter 5 we summarise our work and propose future work in this field.

Full textAbstract:
Despite seemingly discriminatory practices at the border directed towards US citizens, no formal academic work has been conducted on the subject. This study is the first of its kind, which examines the phenomenon of the denying and banning of US citizens from the external Israeli border crossings. It draws upon the cases of 110 US citizens who have been banned or denied from the external Israeli border crossings from 1987-2015. This study finds that denial is often associated with Palestinian Americans, Arab Americans, Muslim Americans, Black Americans and Americans who personally identify as activists or are considered by border officials to be so. It argues that Israel’s actions at their border crossings have become increasingly standardized over time through practices of “stealth authoritarianism” that create the veneer of due process in the execution of a denial or ban and lead to difficulties pursuing redress. Finally, this study puts forth how this practice fits within the broader context of Israeli policies regarding the subjugation of Palestinians living in the occupied Palestinian territories and Israel proper as well as individuals suspected of being activists working towards Palestinian liberation. Ultimately, this study hopes to lay a multi-disciplinary groundwork for understanding the implications of the denial and banning of US citizens at the external Israeli border crossings for those who wish to pursue the topic in the future.

Full textAbstract:
In Britain, the brown long-eared bat, Plecotus auritus, commonly uses the roof spaces of houses as summer roost sites. This study aimed to investigate the roost requirements of this species, particularly in relation to its foraging activity, the composition of colonies, the occupancy of roosts, and whether the selection of particular roost sites affected the fitness of the bats using them. Fifty-six roosts used by P.auritus were located within the study area, in north-east Scotland. By comparing the houses occupied by P.auritus to a random sample of buildings from the same area it was shown that this species preferentially roosted in buildings which were older, higher, and had more roof compartments which were fully lined with wood. In addition, the buildings used as roosts were closer to trees and water and had a large area of woodland within 0.5km. The mean temperature within roosts was 17.9°C, and they were significantly warmer than the random sample of buildings, which had a mean temperature of 16.7°C. When captured, bats were generally euthermic and warmer roost temperatures may have reduced the dependence on torpor. Radio tracking showed that bats foraged mainly in deciduous woodland in the vicinity of the roost, using a series of feeding sites to which they frequently returned, and which were occasionally shared with conspecifics. Females spent most of their foraging time within 0.5km of the roost, while males travelled further. Bats returned to the main roost on 77% of mornings, but also used alternative roost sites, which had cooler microclimates, following nights of low temperature. Colonies were evident in summer roosts between May and October, and the typical size of group seen within the roof was 15-20 bats.

Full textAbstract:
The region of Baḥrayn in eastern Arabia during the post-Qarmāṭian era has received little attention from scholars because of the scarcity of local written sources and the daunting task of gathering scattered small pieces of information from other sources in more than one language. This thesis focuses on the politics, geopolitics, economy, literature and religion of Baḥrayn from c. 1050 to c. 1400 CE. It consists of eight chapters in addition to an introduction and a conclusion. The introduction presents the research framework of the thesis. World-systems Analysis in a pre-capitalist setting is used to analyse Baḥrayn’s hierarchical position in the Near East according to its economic, political and cultural characteristics. It also sets out the historical background and context of the region, presents the thesis’ questions and structure, reviews modern studies and summarises the extant literary and archaeological evidence. Chapter One describes the historical geography and economy of Baḥrayn and analyses the impact of the region’s geography and the wider economic context on its history. Chapter Two studies the two rebellions against the Qarāmiṭa on the island of Uwāl and in the city of al-Qaṭīf, which led to the establishment of the emirate of Āl al-Zajjāj and the emirate of Āl ʿAbbās. Chapters Three and Four deal with the rise and decline of the ʿUyūnid emirate (1077-1230s CE) and study the ʿUyūnids’ institutions, including their administration and army formation. Chapter Five concentrates on the powers that ruled the region of Baḥrayn after the fall of the ʿUyūnid emirate in 1230s CE: the ʿUqaylid emirate in al-Aḥsāʾ and the deserts of Baḥrayn and Najd, and the Iranian-based polities that ruled Uwāl and al-Qaṭīf. Chapter Six focuses on literature produced in Baḥrayn, presenting biographies of its poets and analyses of the commentary of the poetry collection of the poet ʿAlī ibn al-Muqarrab al-ʿUyūnī and Abū al-Buhlūl’s letter. It also examines the relationship between the poets and the emirs of the ʿUyūnid emirate. Finally, Chapters Seven and Eight shed light on religion in Baḥrayn. They examine the region’s communities of Shīʿites and Sunnis which appear to have adhered to popular forms of Ismāʿīlism, Twelverism, Ḥanafism and Shāfiʿism. The question of scholars and scholarship in Baḥrayn from the twelfth to the fourteenth century is revisited. It is argued that the current consensus that attributes a number of 12th-14th century Twelver scholars who held the nisba of al-Baḥrānī to Baḥrayn lacks early evidence, appeared in a Safavid context and indeed contrasts with the evidence for the region’s peripherality and other evidence that suggests a lack of scholars in the region.

Connolly, Michael. "Easy cases making bad law : the English judiciary, discrimination law, and the statutory interpretation." Thesis, University College London (University of London), 2018. http://discovery.ucl.ac.uk/10044510/.
Full textAbstract:
The definitions of discrimination provided by equality legislation are a measure of how far a society is willing to challenge deep-seated assumptions, attitudes, and patterns of inequality. The judiciary has a major role in shaping these definitions. This is evident from the antecedent American cases and those of the Court of Justice of the European Union, which worked with more aspirational than detailed legislative provisions. One might conclude that the legislation coming before the English courts was thus ‘ready-made’, presenting the judiciary with few interpretive difficulties. But on many occasions this has proved not to be the case, with the senior English courts producing a number of highly contentious decisions. Commentators, heavily critical of many of these cases, tend to analyse them by reference to external understandings of concept, theory, or policy. This work offers a unique internal critique of the process producing the cases subject to such academic scrutiny. It makes a textual analysis of leading English judgments on the definitions of discrimination, and does so through the lens of statutory interpretation - the judge’s primary function. The scrutiny finds that these judgments are technically flawed in terms of the process of statutory interpretation and the definitions produced; it also finds them to be overcomplicated, excessively long, and often unduly restrictive. As such, the thesis is that these cases were better, and more easily, resolvable using conventional methods of interpretation, which would also shape the definitions better to reflect the policies underlying the legislation. Although highlighting inexpert reasoning, the textual scrutiny reveals other threads, particularly notable in the narrow interpretations. There is an adherence to the common law’s notion of binary litigation, envisaging just two individual litigants (e.g. a worker and employer) necessitating a harmed individual and fault-based liability; this is at odds with the societal and group-based purpose of the legislation. One can also detect a lingering historical negative or indifferent attitude to matters of equality, often realised nowadays with an assortment of personal predilections. Consequently, suggestions for reform are based around these findings.

DEVELOPMENT AND VALIDATION OF A LIGHT WEIGHT, ENERGY DENSE, READY TO EAT (RTE) BAR
Jacob Wilhelm-Maria Heick
Providing additional calories in the form of an RTE bar to endurance athletes will increase performance and muscle re-synthesis, reduce muscle breakdown, and shorten recovery time. An RTE bar containing a blend of dairy proteins and carbohydrates will create a product with superior functionality, including bioactive and immunity enhancing properties from dairy derived ingredients. The protein will provide benefits in the form of easily digestible calories, essential amino acids and physical satiate.
A formulation was developed and optimized, resulting in a final product that meets the required nutritional profile: 400kcal, 25grams protein per 100 gram serving size. The desired physical characteristics were achieved through processing by both conventional baking and freeze drying. The latter method improves the stability and functionality of the RTE bar.
In order to meet the protein requirements of the RTE bar without compromising sensory properties, a unique protein source was developed. Using high concentrations of conventional protein sources like Whey Protein Concentrate (WPC) resulted in stale off-flavors and unappealing textures. Milk Protein Precipitate (MPP) was developed for this formulation. MPP is a curd-like ingredient created through the combined heat and acid precipitation of dairy proteins. MPP can be used effectively in high concentrations provides a subtle dairy flavor. MPP delivers a balance of casein and whey, similar to that found in milk.
The effectiveness of the RTE bar formulation as a post exercise recovery food was evaluated in a human studies experiment conducted on the Cal Poly campus. The human subjects study utilized 34 Cal Poly students in a single-blind cross-over design experiment. The study compared the effects of this high protein RTE bar against a calorically equal carbohydrate bar. The bars were administered after subjects completed the pre-assigned hikes on three consecutive days. Following the cross-over design, subjects received the alternate bar in the second period of the experiment. Several blood markers involved in metabolism and inflammation were measured before and after the two treatment periods. No blood marker showed a statistically significant difference between bars, but several trends were observed. Body weight and fat percent were also unaffected by bar composition.

Full textAbstract:
2020 was the year a pandemic hit the world. Along with that, media was swamped with information about death numbers, epidemiological facts, and an urge to inform people on the current situation. The information campaigns by the Austrian government were no exception. Highlighted in these campaigns were children, especially when it came to the relationship with grandparents or presenting how to keep distance through the display of a baby elephant. A visual analysis of information campaigns was conducted in order to find out how children were presented in these campaigns and to further identify what messages were conveyed in relation to children. Four themes emerged during the research process that gave answers to the research questions posed. The results show that children were shown in relation to their grandparents or their family. Moreover, they were often used to present innocence and in need of protection, but paradoxically also as socially responsible over the health and well-being of the older generation. Often so, they were used mimicking the voice of the initiators of the campaign “Look after yourself, look after me” and even used in relation to distance keeping where a child in a baby elephant costume “taught” adults how to keep distance. Research on children’s representation in media in relation to a pandemic is rather slim and there is an urgent need to gain more knowledge in this area, since this would broaden the awareness of how children are represented and seen by a society the reside within.

Full textAbstract:
La modification d’électrodes par des films de silice mésoporeuse (FSM) ouvre des perspectives intéressantes dans le développement de capteurs électrochimiques. En particulier, la combinaison de la méthode électrochimique EASA (electrochemically-assisted self-assembly) permet d’obtenir des films fins et réguliers de silice mésoporeuse, de structure hexagonale et des pores perpendiculaire à la surface du support. Ces caractéristiques singulières contribuent à des transports de matière extrêmement rapides et indispensables aux applications type capteurs. La première partie du projet est centrée sur la réduction de l'épaisseur du FSM pour obtenir le plus fin tout en préservant sa structure hexagonale organisée et minimiser les effets négatifs du dépôt tout en ne gardant que ses bénéfices. Nous avons tout d’abord déterminé que, par la méthode de déposition EASA, l’épaisseur minimale d’un film homogène et sans défaut pouvant être atteinte dans nos conditions opératoires ([Si] = 100 mM, 32 mM CTAB) est de 80 ± 9 nm pour 10 s du potentiel -1.3V/Ag appliqué. Notre approche pour obtenir des couches plus fines que cela a consisté à dissoudre le FSM par voie humide, en utilisant le fluorure d’ammonium, NH4F, comme réactif «doux». La dissolution la plus contrôlée a été observée pour les FSMs dont le tensioactif est conservé dans la structure poreuse. La présence du CTAB favorise le transport et l’accumulation des ions fluorure dans le film accélérant ainsi la réaction (1.1 nm/min avec NH4F 0.05 M). L’épaisseur du FSM le plus fin obtenu dans ces conditions est de 28 ± 9 nm. Lorsque le traitement est mené sur des FSMs pour lesquels le tensioactif a été extrait par voie humide ou par calcination, l’épaisseur la plus petite atteinte sans créer de défaut dans le film est seulement de 57 ± 11 nm. Dans la deuxième partie de l'étude, les FSMs ont été fonctionnalisés par un complexe organométallique de ruthénium(II) dans le but d’essayer de développer une plateforme d'électrochimiluminescence pour la détection du glyphosate. L’originalité de l’approche est le choix d’immobiliser de manière covalente le complexe ruthénium(II) tris(bipyridine), Ru(bpy)₃²⁺, au sein du FSM. L’approche par chimie «click» a été privilégiée et réalisée sur un FSM modifiée par des groupements azoture préparé par co-condensation. Les premiers résultats électrochimiques obtenus en présence de glyphosate ont montré que la présence du pesticide conduit à une modification du signal électrochimique quelle que soit la nature de l’électrode utilisée. La détection de l’herbicide est ainsi possible. On remarque cependant que la nature du signal enregistré avec une électrode modifiée par un FSM où le complexe organométallique a été préalablement greffé est différent de celui obtenu avec les autres électrodes et pas encore totalement expliquéThe combination of rich surface chemistry of silica and ordered perpendicularly-standing hexagonal mesostructure of films generated by EASA makes this material a perfect choice for use as the electrode coatings. In this light, improvement of film design is a constant challenge in order to benefit from porous layer and to increase the efficiency of electrochemical sensors. The first part of project was centred around the optimisation of the film thickness towards the thinnest with preservation of the beneficial hexagonal structure. The mesoporous silica film (MSF) thickness is a parameter that can affect the mass transport through the silica coating to the electrode specifically because of the reactivity of surface silanol groups. Thinning of the MSF can facilitate the diffusion of species, while keeping the presence of the beneficial silica layer can increase the electrochemical response, hence, the sensitivity of analysis. Two approaches were used in order to decrease thickness. The first was a study of the effect of the deposition time during the modification of the electrode (EASA process). The second one was the wet etching of film after its deposition. The thinnest uniform MSFs, which can be generated on indium tin oxide (ITO) surface, require minimum 10 seconds deposition with an applied potential equal to -1.3 V and a 100 mM silane-containing sol. This gave rise to 80 ± 9 nm coating. Post-synthesis etching with the soft fluoride solution of ammonium fluoride, NH4F, allowed to control the decrease of the MSF thickness. By keeping the surfactant inside the silica pores, template agent for the synthesis, the kinetic of the etching reaction was faster, but with a more homogeneous dissolution. It was possible to obtain the thinnest ordered MSF in comparison with an etching procedure conducted on MSF after the extraction of the template. The profilometry determined thickness of well-structured film with vertical pore orientation was respectively of 28 ± 9 nm for the templated silica films and 57 ± 11 nm for films without surfactant inside their pores. In the second part of the study, MSFs were applied to modify ITO electrodes for the development of electrochemiluminescence platform for detection of amine-containing herbicide glyphosate using co-reactant system with Ru(bpy)₃²⁺. Comparison between physical and chemical immobilisation of the organometallic agent was studied. Covalent functionalisation was achievable due to introduction of azide functions on co-condensation step with their further coupling with propargyl-functionalised derivative of Ru(bpy)₃²⁺ complex by Huisgen 1,3-cycloaddition reaction. The effect of the herbicide addition was investigated using electrodes with immobilised by two approaches Ru(bpy)₃²⁺ complex as well as in solution of Ru(bpy)₃²⁺, operating bare ITO electrode and ITO electrode covered with unmodified MSF. The evolution of electrochemical signal was used to conclude on the possibility to detect glyphosate

Full textAbstract:
Ridterapi har på senare tid börjat användas som en komplettarande behandlingsmetod för psykosocial problematik. I dagsläget finns ännu inte mycket forskning inom ämnet och behandlingsmetoden är vare sig speciellt känd eller etablerad. I denna uppsats görs en kartläggning av socialsekreterares uppfattning och kännedom om ridterapi. Undersökningen var i form av en enkät och genomfördes i Uppsala län där socialsekreterare som arbetar med placeringar på HVB-hem medverkade. Vi ville se om olika faktorer som exempelvis ett eget djurintresse, kunskap om behandlingsmetoden, kön och ålder kunde påverka deras inställning till ridterapi. Resultatet av undersökningen visade att våra respondenters generella attityd till behandligsmetoden var positiv och att de i hög grad kunde tänka sig att göra sådana placeringar och de olika faktorerna vi jämfört med i undersökningen påverkade inte resultatet nämnvärt. Dock visade det sig att det var många som inte kände till vad ridterapi var.Recently it has been more common to use Equine assisted therapy (EAT) as a complementary treatment for psychosocial issues. Today, not much research has been done in this area and therapy method is neither known nor established. In this essay a survey has been done in the purpose to get a grip of social workers attitude toward and knowledge about EAT. The survey was performed in Uppsala County and social workers who put clients in care or residence homes (HVB) were queried. We wanted to investigate how different factors such as an interest in animals, knowledge about the therapy method, gender or age could affect the respondents attitude toward EAT. The result from our investigation has shown that our respondents had an overall positive attitude toward EAT and that they to a high degree would make such a placement. The different factors that we compared with did not affect the result in a high degree. However, our results also showed that the majority of our respondents did not know about EAT or what it can be used for.

Full textAbstract:
Cette étude concerne les bas-reliefs rupestres des montagnes du Kurdistan irakien, notamment ceux découverts dans les trois provinces de Dohuk, Erbil et Sulaymaniyeh.Les bas-reliefs sont une source importante de données sur les sociétés du Proche-Orient ancien. Ils sont des témoignages d’idéologies, de croyances, de cérémonies et de rituels anciens. Nous avons pris en compte une large période depuis le début de l’âge du Bronze jusqu’au 3e siècle après J.-C. Cela concerne un corpus d’étude de 132 objets dont 43 bas-reliefs du Kurdistan irakien. Les bas-reliefs étaient aussi un moyen de satisfaire le désir d'immortalité des gouvernants ; une partie de ces bas-reliefs représentent une iconographie royale avec des scènes de guerre et de victoire sur les ennemis, de couronnement royal, la mise en place des projets d’irrigation, d’autres concernent des événements religieux.L’analyse des bas-reliefs a été effectuée à partir d’observations réalisées sur le terrain et l’étude de la bibliographie existante afin de mieux connaître les causes de leur création. Nous disposons de mesures précises, de photos et de schémas de ces bas-reliefs, élaborés de façon exhaustive et similaire, ce qui permet ensuite de les comparer avec d'autres vestiges archéologiques bien datés. Nous les avons traité sur les plans technique et artistique, en étudiant l’iconographie, les décors, les personnages, les vêtements, les armes et les symboles divins que l’on retrouve sur ces œuvres. Cette analyse détaillée des éléments figurés et des scènes de ces reliefs est très utile pour connaitre leur contexte historique qui étaient encore mal connues, en raison du grand nombre d’avis contradictoires émis par les précédents chercheurs.Nous retraçons à travers ces bas-reliefs une fresque de l’histoire du Kurdistan irakien qui va de 3000 avant J.-C à 300 ans après J.-CThis study concerns the rock reliefs of the mountains of the Kurdistan (Iraq), including those discovered in three provinces of Dohuk, Erbil and Sulaymaniyeh.The reliefs are an important source of data concerning the societies of the Ancient Near East. They have been used as evidence of former ideologies, beliefs, ceremonies and rituals. We have taken in account a large period from the early Bronze Age until the 3rd century after AD. This concerns a corpus of study including 132 objects which 43 low-reliefs found in the Iraqi Kurdistan. The reliefs were also a way to satisfy the desire for immortality of previous rulers; some of these reliefs represent a royal iconography with scenes of war and victory on the enemies, royal coronation, the implementation of projects of irrigation; others relate to religious events.The analysis of the low-reliefs was conducted from observations of the field and by the study of the previous bibliography to have a better knowledge of the causes of their creations. We have a description of these reliefs with accurate measurements, photos, and drawing, done with exhaustive and similar methods, which then allows them to compare with other well dated archaeological evidence. Then we have dealed with these reliefs on technical and artistic level, by studying their iconography, the decors, the characters, the clothes, the weapons and the divine symbols found on these works. This detailed analysis of the figuredelements and sceneries of these reliefs is very useful to know their historic context that were still not wellknown, because of the large number of conflicting opinions from the previous researchers.We track through these low-reliefs a fresco of the Iraqi Kurdistan history that goes from 3000 BC to 300 years after AD

Exemple des formations triasiques et jurassiques dans le nord-est de la France." Thesis, Université de Lorraine, 2012. http://www.theses.fr/2012LORR0405/document.
Full textAbstract:
L'hétérogénéité spatiale est un trait caractéristique des aquifères calcaires. Conditionnée par le karst et ses morphologies, cette hétérogénéité explique la fréquente sous-exploitation des réserves de ces hydrosystèmes mais également le degré lacunaire de connaissance de leurs fonctionnements. Nous avons voulu, dans cette recherche, approfondir cette connaissance en scrutant le fonctionnement des aquifères calcaires qui arment les bas plateaux du Nord-Est de la France. Trois de ces bas plateaux ont été retenus, ceux du Dogger et de l'Oxfordien (Jurassique) et celui du Muschelkalk (Trias). Afin de comprendre comment s'organisent les écoulements sur et dans ces trois systèmes, notre démarche s'articule autour de deux principaux axes ; le premier concerne l'identification des modalités de l'écoulement et le second est consacré à leur quantification. En pratique, la connaissance des modalités de circulation a été recherchée à travers l'étude des différents paramètres structurels (géologique, tectonique, karstique) et conjoncturels (précipitation, évapotranspiration) qui interagissent dans le cycle de l'eau. Nous montrons que la variété de fonctionnements hydrologiques observés, à l'échelle du domaine d'étude, est conditionnée principalement par les paramètres structurels ; l'hétérogénéité lithologique, notamment, apparaît comme une clef fonctionnelle déterminante, d'une part, par l'existence d'une multiplicité de nappes d'eau et d'autre part, par son rôle dans la karstogenèse. Les morphologies du karst s'observent principalement sur les secteurs de contact lithostratigraphique et nous avons pu établir, à travers une répartition spatiale des phénomènes du karst (en surface et en souterrain), que ces trois plateaux sont majoritairement déconnectés du karst et dominés par des processus de circulation lents, de l'infiltration à la vidange aquifère. Afin d'apporter des éléments de quantification sur les circulations, une analyse hydroclimatique et géochimique d'exutoires de petites dimensions a été ensuite menée. C'est ainsi qu'une petite dizaine de sources et de bassins versants, localisés dans des contextes physiographiques variés, ont fait l'objet de suivis sur plusieurs cycles hydrologiques. L'analyse nous a permis de préciser les caractères hydrodynamiques de deux grands types de comportement observés au sein des bas plateaux étudiés : le comportement fissural et le comportement karstique. Le comportement fissural se manifeste, à l'échelle annuelle, par un filtrage important des précipitations par les systèmes (forte inertie des valeurs de débits et de conductivités électriques) et également par de lents processus de mise en charge à l'échelle des évènements de crue. Le comportement karstique, quant à lui, est attesté, à l'échelle annuelle, par des pluies moyennement filtrées par les systèmes mais aussi par des variations hydrogéochimiques accusées lors des sollicitations pluviométriques majeures, en lien avec la transmissivité importante de ces milieuxThe spatial heterogeneity is a feature of limestone aquifers. Conditioned by the karst and its morphologies, this heterogeneity explains the frequent under-exploitation of these hydrosystem reserves but it also explains the incomplete degree of knowledge of their functionings. In this research we wanted to deepen this knowledge by scrutinizing the functioning of the limestone aquifers which arm the low plateaus of the North-East of France. Three of these low plateaus held our attention, those of Dogger and Oxfordian (Jurassic) and the one of Muschelkalk (Triassic). In order to understand how the flows on and into these three systems are organized, our approach focuses on two main axes ; the first one concerns the identification of the modes of flow and the second one is devoted to quantification. In practice, the knowledge of the flow modes was investigated through the study of various structural parameters (geology, tectonics, karst) and conjunctural parameters (precipitation, evapotranspiration) interacting the water cycle. We show that the variety of hydrological functionings which are observed, on the scale of the study area, is mainly dependent on the structural parameters ; the lithological heterogeneity, in particular, appears as a determining functional key, on the one hand, by the existence of a multiplicity of groundwater and on the other hand, by its role in the karstogenesis. The morphologies of the karst are primarily obvious on the areas of lithostratigraphic contact and we were able to establish, through a spatial distribution of karst phenomena (on and underground), that these three plateaus are mainly disconnected from the karst and run by slow-flow processes, from infiltration to ground water discharge. In order to provide some quantifications of the circulations, a hydroclimatic and geochemical analysis of small outlets was then conducted. Thus a dozen springs and catchments, located in various physiographic settings have been surveyed for several water years. The analysis allowed us to specify the hydrodynamic characteristics of two types of behavior observed in the low plateaus we studied: the fissural behavior and the karstic behavior. The fissural behavior appears, on an annual scale, through a significant rainfall filtering of the systems (high inertia of the values of discharges and electrical conductivities) and also by slow charging processes when flood events occur. The karst behavior, meanwhile, is evidenced on an annual scale, by a moderately rainy filtering of the systems but also by hydrogeochemical variations accused during major rainfall solicitations in connection with the important transmissivity of these environments

Full textAbstract:
Background: The transition from trainee to newly-registered (novice) practitioner is regarded as the most stressful and challenging of time of a healthcare professional's career. Community pharmacists are unusual in that they transition into roles where they commonly work as the sole pharmacist, manage a team of support staff and are accountable from day one of professional registration (without any formal support structure), yet little research exists in this area. This study aimed to identify the transition challenges faced by novice community pharmacists and to develop and feasibility test an evidence-based intervention to ease their transitions to independent practitioners. Methods: Medical Research Council guidance for developing complex interventions was used to frame this programme of work. During development, evidence from existing literature and an exploratory nominal group study identified and prioritised the challenges faced by novice community pharmacists. Findings informed the iterative design process for a peer-coaching intervention with the following components; a social media group, one-to-one coaching, a handbook, group activities and weekly clinical/practice scenarios for group discussion. Twelve novice community pharmacists were recruited purposively to participate in the draft intervention, which was evaluated using semi-structured telephone interviews. Results: Twenty-five participants took part in homogenous group discussions consisting of novice community pharmacists, early career pharmacists, pre-registration tutors and pharmacy colleagues. Similarly to challenges reported by novice doctors and nurses, nominal group discussions identified the following challenges [in order of importance]; relationship management; lack of confidence; decision-making; being in charge and accountable; and adapting to the workplace. Relationship management was attributed to novices' lack of affective skills. There were some differences however in the challenges reported by novice community pharmacists, such as power struggles (with managers or pharmacy colleagues), inverse hierarchy, professional isolation, target culture and full immediate accountability. A number of factors perpetuating these differences were perceived to increase the weight of professional accountability and augment stress; the retail community pharmacy context, the relative lack of support and isolation from peers. Hence, the draft intervention focussed on supporting the novice community pharmacist to develop cognitive and affective skills. All participants viewed the social media forum as the most valuable component because it provided a confidential space for reassurance, feedback, and sharing or discussing practice experiences. Participants also valued one-to-one discussions with the coach, which supported meaningful reflection and developing self-awareness. Outcomes reported by all participants included increased self-efficacy, increased confidence in decision-making/managing others, an increased sense of preparedness and the ability to cope during transition. Through group components, novice community pharmacists developed and reported feeling less isolated in the workplace. Conclusions: This novel programme of work revealed the challenges faced by novice community pharmacists during transition. Findings suggest that a lack of affective and cognitive skills, the demands of the job and professional isolation caused novices to experience psychosocial stress and high job strain. A group peer-coaching intervention designed to ease the transitions of novice community pharmacists was reported to be acceptable, feasible and beneficial. Study findings led to some recommendations for transition support interventions: incorporate psychosocial support with developmental activities; provide a supportive learning space for developmental discourse that is accessible facilitated and structured; and offer coaching and supported reflection from an experienced pharmacist coach.

Full textAbstract:
The structure and function of coastal marshes results from a complex interaction of biotic and abiotic processes that continually influence the characteristics of marsh vegetation. A great deal of research has focused on how tidal processes influence vegetation dynamics along the Atlantic coast, but few studies have investigated the influence of similar processes in the marshes along the Gulf of Mexico. This study aims to identify the characteristic vegetation assemblages of the coastal marshes bordering the East Bay of Galveston Bay, Texas, and identify if elevation, inundation frequency and burning frequency are important to their structure.
To identify characteristic vegetation assemblages, hierarchical cluster analysis was used. The cluster analysis resulted in seven statistically different vegetation assemblages that were used in diversity analysis and classification and regression analysis (CART) as dependent variables.
Diversity measures were calculated at both the plot and assemblage scale using Shannon's diversity index and species richness. The resulting diversity measures were used as predictor variables in the CART analysis as well as regression analysis.
Hydrologic modeling was accomplished using Mike 21, a flow and wave simulation model, along with a geographic information system (GIS), to model hourly inundation frequency at each of the sampled plots. The inundation frequency was then used as a predictor variable in the CART analysis and regression analysis.
This study found that the main factor contributing to species richness was elevation. Vegetation assemblages at high elevations generally had high diversity, and assemblages at low elevations had lower diversity. Elevation and inundation frequency are inversely related, and the strong correlation between species richness and elevation also assumes that inundation frequency is important in structuring the marsh. Burn frequencies had no influence on diversity in general, but more frequent burning did result in monospecific stands of Spartina patens at Anahuac NWR.

The seasonal asymmetry in coastal temperatures on Hudson Bay was explored and evaluated as a proxy to hindcast sea ice conditions prior to 1972. Various indices of air temperature difference (∆T) between Churchill, MB and Inukjuak, QC were tested for linear correlations with spatially averaged sea ice concentration (SIC) and ice-free season length (IFS). A multiple regression equation employing a 31-day average of peak ∆T and a 61-day average of temperature during freeze-up reproduced the IFS record with an average error of 8.1 days. This equation was employed to extend the IFS record by 28 years. The resulting 68-year time series revealed a significant increasing trend most pronounced from 1985 to 2011. Hindcast data helped eliminate low-frequency climate oscillations of periodicity <68 years as a source of this trend, lending further evidence to the growing consensus of a declining sea ice being the result of anthropogenic climate forcing.

This study aims to: (1) better define veining styles and characterize the mineralizing fluids using petrography, fluid inclusions, geochronology and stable isotopes, (2) compare barren and auriferous veins from deposits along the East Bay Trend, and (3) compare the fluid history of the East Bay Trend to the Campbell-Red Lake gold deposit to determine the gold potential along this trend.

Continental shelves are active sites of air-sea CO2 exchange and represent an important component to the global carbon budget. In this study, we investigated the CO2 system and pertinent hydrographic parameters in two distinct continental shelf systems in the Northwest Pacific in summer 2014: the East China Sea shelf (ECSS) and the Peter the Great Bay (PGB) of the Japan/East Sea. The results show that the PGB acted as a source of atmospheric CO2, while the ECSS was a sink. We suggest that the observed divergent behaviors in terms of CO2 absorption between the PGB and the ECSS may be associated with their difference in receiving river runoff. Under the influence of the Yangtze River, the nutrient discharge into the ECSS is much higher than that into the PGB, where only a few small rivers empty into. The high nutrient discharge into the ECSS may stimulate high biological production, which may drawdown CO2 and thereby driving the ECSS to act as a CO2 sink despite high temperature in summer. On the contrary, the temperature effect may dominate over the effect of biological production in the PGB due to the limited nutrient discharge, and thus turn the PGB to be a source of atmospheric CO2 during the warm summer season. The comparison between the present study and other shelf systems within the similar latitudinal zone demonstrates that whether the temperate shelf acting as a source or a sink of atmospheric CO2 is largely controlled by the influence of river discharge and circulation pattern. For the shelf system impacted by large river discharge or cold current, it is inclined to be a source of atmospheric CO2, meanwhile for that without the influence of large river or that affected by warm current, it tends to act as a sink.

Benthic microalgal community composition on an ephemerally submerged sandflat at East Beach, Galveston Island, Texas was studied to determine the spatial and temporal variability of total biomass and community composition and its responses to experimental manipulations of two environmental factors (salinity and nutrients). Four field studies were conducted between August 2004 and February 2005. The community consisted of two major algal groups, diatoms, and cyanobacteria with two less abundant groups, green algae, and phototrophic bacteria. Spatial variability showed that patch sizes of 12 - 25 m were detected over larger scales with smaller scale (cm) patches of approximately 28 - 201 cm^-2 contained within the larger patches. The second study examined the spatio-temporal variability of BMA over a 21-month period in a 1,000 m^2 area. Sampling location and date explained a significant amount of the variability in the abundances of algal groups, which were positively correlated with the water content of the sediments and negatively correlated with temperature (sediment and water). All of the algal groups showed a seasonal pattern with higher abundances measured in the winter months and lower abundances found during the summer. BMA biomass (100 mg Chl a m^-2 or greater) maxima occurred at temperatures less than 22 degrees C and sediment water content greater than 15% (g water g sediment^-1).
BMA response to different salinities and nutrient (N+P) amended sediments was assessed in four bioassays conducted over a 6-month period (Aug. 2004, Oct. 2004, Dec. 2004, and Feb. 2005). In the salinity study, the treatments that were either 100% or partially diluted with deionized water had the lowest BMA biomass over all. Chlorophyll a and fucoxanthin were significantly affected by salinity with higher abundances found in salinities that averaged 15 with a preference for salinities greater than 22. Chlorophyll b was affected by salinity with higher abundances measured in the treatments with lowest salinity (DL and DI); and was affected by the time of year. This would suggest that this algal group prefers an environment with salinity less than 2 but can easily adapt to environments with higher salinities. BMA abundances were not significantly affected by the nutrient amended sediment, but were significantly affected by stations with higher water content, and during the cooler months (Dec. 2004 and Feb. 2005).
