12	Projections of Sea Level Along the East Coast of North America Love, Ryan January 2014 (has links) Projections of sea level rise for the east coast of North America at 2100CE were generated considering contributions from: ocean warming, land ice melting and isostatic land motion. The primary contribution of this study is the development of an improved Glacial Isostatic Adjustment (GIA) model that includes an assessment of model uncertainty using 36 ice loading histories, 363 Earth models and a new sea level proxy database comprising over 500 sea level index points. We find that, while there are differences between our projections and the Global Mean Sea Level (GMSL) projections from the recent International Panel on Climate Change (IPCC) Assessment Report, the two sets of results agree to within uncertainty largely because some of the regional processes cancel. Our results indicate that the isostatic signal is large, contributing up to 1/4 of sea level change at 2100CE, and so must be included to generate accurate projections for this region.

13	Jail Administrators' Compliance With the Prison Rape Elimination Act Lee, Leone M. 01 January 2019 (has links) Correctional institutions across the United States continue to experience prisoner sexual assault despite the enactment of the Prison Rape Elimination Act of 2003 (PREA). The purpose of this correlational study was to examine the association between jail administrators' difficulty complying with the PREA and their transformational leadership styles. The theories of punctuated equilibrium theory and general strain theory formed the theoretical framework of the study. The data were collected through an Internet-based survey from 22 local and regional jail administrators from the East Coast. Data analysis using Pearson's correlation coefficient was performed on leadership scores to test the hypotheses. There were results showed no statistically significant correlations between 5 attributes of transformational leadership styles and PREA compliance. A multiple linear regression analysis was performed; however, this question could not be answered because 2 fundamental assumptions of multiple linear regressions were not satisfied. Social change implications of this study include using the study results to expand leadership development programs that could influence a full range of leadership skills essential for addressing the present and future policies of PREA affecting correctional facilities in the United States.

14	Diagenetic evolution of some modern and ancient cold seep-carbonates from East Coast Basin, New Zealand. Ewen, Sarah Maree January 2009 (has links) Cold seep-carbonates are the microbially mediated by-products of the anaerobic oxidation of methane (AOM) at seafloor cold seeps, and are widespread about modern continental margins and in the geologic record. Some modern and Miocene examples of cold seep-carbonates from the East Coast Basin, North Island, New Zealand have been analysed in this study, to characterise and determine their carbonate fabrics, elemental and mineralogical composition, and stable δ18O and δ13C isotope signatures, so as to provide insights into the diagenetic changes associated with the lithification and burial of seep-carbonates. The ancient samples were collected from the onshore middle Miocene Tauwhareparae (TWP) seep deposit, while the modern samples were obtained from the National Institute of Water and Atmosphere (NIWA) Cruise TAN0616 (November 2006) from Ritchie Ridge, offshore Hikurangi Margin. A paragenetic sequence of diagenetic events involving early aragonitic phases, followed by late calcitic phases is defined for the seep-carbonates. This sequence likely has relevance for understanding the fluid-cement histories of seep-carbonates more widely. Two main carbonate mineralogies occur in each of the sample groups - modern samples are aragonitic or dolomitic, while the ancient ones consist dominantly of either aragonite or calcite. Thus, aragonite common to both sample groups, and is interpreted to represent the initial primary carbonate precipitate in hydrocarbon seep provinces under specific fluid flux and local pore-water chemistry conditions. Aragonite morphologies range from microcrystalline carbonate ('micarb'), to acicular aragonites that may form botryoids or spherulites. Dolomite occurs in those modern samples which appear to constitute exhumed remnants of a former subsurface 'seep plumbing system', and so are strictly not true seabed 'seep-carbonates', but instead are part of the larger hydrocarbon seep province. Calcite in the ancient samples is either a product of alteration and neomorphic transformation of aragonite, or derives from late stage cementation from burial fluids. As a result of their formation processes, the calcites are generally recrystallised and have equant or 'cellular' textures. Stable δ13C and δ18O isotope cross-plots reveal a large spread of values for the sample groups. Ancient samples range from δ13C -8 to -50 PDB and δ18O -5.5 to +2 PDB. Modern samples have δ13C values from -6 to -41 PDB and δ18O values ranging from +2.6 to +6.7 PDB. The δ13C values suggest the majority of the methane that formed these seep-carbonates is of thermogenic origin, although some mixing from other carbon sources may have occurred. The positive δ18O signatures are suggestive of carbonate formation during dissociation of gas hydrates, while the negative values possibly indicate that some of the formation fluids were warmer than normal in the 17 - 30 C range.

15	Arsenic and Selected Elements in Marine Photosynthetic Organisms,South-East Coast, NSW, Australia. Thomson, Danielle, n/a January 2006 (has links) The cycling of arsenic in the marine photosynthetic plants and algae was examined by analysing total arsenic concentrations and arsenic species in selected marine photosynthetic organisms from the south-east coast, NSW, Australia. A range of elements required for metabolism in photosynthetic organisms were also analysed to determine if any relationship between these elements and arsenic concentrations occurred. Organisms were selected from salt marsh and mangrove ecosystems, marine inter-tidal and estuarine environments, and two species of marine phytoplankton cultured, to represent the different marine environments that primary producers inhabit. Organisms selected were compared to species within their own environment and then a comparison made between the varying ecosystems. In the salt marsh and mangrove ecosystems, the leaves of four species, the mangrove Avicennia marina, the samphire Sarcocornia quinqueflora, the seablight Suaeda australis, and the seagrass Posidonia australis were sampled from three locations from the south-east coast of NSW using nested sampling. Mean total arsenic concentrations (mean � sd) dry mass for all locations were A. marina (0.38 � 0.18 �g g-1 to 1.2 � 0.7 �g g-1), S. quinqueflora (0.13 � 0.06 �g g-1 to 0.46 � 0.22 �g g-1), S. australis (0.03 � 0.06 �g g-1 to 0.05 � 0.03 �g g-1)and P. australis (0.34 � 0.10 �g g-1 to 0.65 � 0.26 �g g-1). Arsenic concentrations were significantly different between species and locations but were consistently low compared to marine macroalgae species. Significant relationships between As and Fe concentrations for A. marina, S. quinqueflora and P. australis and negative relationship between As and Zn concentrations for S. quinqueflora could partially explain arsenic concentrations in these species. No relationship between As and P concentrations were found in this study. All terrestrial species contained predominantly inorganic arsenic in the water extractable and residue fractions with minor concentrations of DMA in the water-soluble fraction. P. australis also contained dimethylated glycerol and phosphate arsenoriboses. The presence of arsenobetaine, arsenocholine and trimethylated glycerol arsonioribose is most likely due to the presence of epiphytes on fronds on P. australis. In contrast, macroalgae contained higher total arsenic concentrations compared to marine terrestrial angiosperms. Total arsenic concentrations also varied between classes of algae: red macroalgae 4.3 �g g-1 to 24.7 �g g-1, green macroalgae 8.0 �g g-1 to 11.0 �g g-1 and blue green algae 10.4 �g g-1 and 18.4 �g g-1. No significant relations were found between As concentrations and concentrations of Fe, Co, Cu, Mn, Mo, Mg, P and Zn concentrations, elements that are required by macroalgae for photosynthesis and growth. Distinct differences between algal classes were found for the proportion of arsenic species present in the lipid and water-soluble fractions, with green algae having a higher proportion of As in lipids than red or estuarine algae. Acid hydrolysis of the lipid extract revealed DMA, glycerol arsenoribose and TMA based arsenolipids. Within water-soluble extracts, red and blue-green algae contained a greater proportion of arsenic as inorganic and simple methylated arsenic species compared to green algae, which contained predominantly glycerol arsenoribose. Arsenobetaine, arsenocholine and tetramethylarsonium was also present in water-soluble extracts but is not normally identified with macroalgae and is again likely due to the presence of attached epiphytes. Residue extracts contained predominantly inorganic arsenic, most likely associated with insoluble constituents of the cell. Mean arsenic concentrations in the green microalgae Dunaliella tertiolecta were 13.3 �g g-1 to 14.5 �g g-1, which is similar to arsenic concentrations found in green macroalgae in this study. Diatom Phaeodactylum tricornutum arsenic concentrations were 1.62 �g g-1 to 2.08 �g g-1. Varying the orthophosphate concentrations had little effect on arsenic uptake of microalgae. D. tertiolecta and P. tricornutum metabolised arsenic, forming simple methylated arsenic species and arsenic riboses. The ratio of phosphate to glycerol arsenoriboses was higher than that normally found in green macroalgae. The hydrolysed lipid fraction contained DMA arsenolipid (16-96%) with minor proportions of phosphate arsenoribose (4-23%). D. tertiolecta at f/10 phosphate concentration, however, contained glycerol arsenoribose and another arsenic lipid with similar retention as TMAO as well as DMA. The similarities between arsenic species in the water-soluble hydrolysed lipids and water-soluble extracts, especially for P. tricornutum, suggests that cells readily bind arsenic within lipids, either for membrane structure or storage, releasing arsenic species into the cytosol as degradation of lipids occurs. Inorganic arsenic was sequestered into insoluble components of the cell. Arsenic species present in D. tertiolecta at lower phosphate concentrations (f/10) were different to other phosphate concentrations (f/2, f/5), and require further investigation to determine whether this is a species-specific response as a result of phosphate deficiency. Although there are similarities in arsenic concentrations and arsenic species in marine photosynthetic organisms, it is evident that response to environmental concentrations of arsenic in uncontaminated environments is dependent on the mode of transfer from the environment, the influence of other elements in arsenic uptake and the ability of the organism to metabolise and sequester inorganic arsenic within the cell. It is not scientifically sound to generalise on arsenic metabolism in �marine plants� when species and the ecosystem in which they exist may influence the transformation of arsenic in higher marine organisms. There is no evidence to suggest that angiosperms produce AB as arsenic is mostly present as inorganic As, with little or no arsenic present in the lipids. However, marine macro- and microalgae both contain lipids with arsenic moieties that may be precursors for AB transformation. Specifically, the presence of TMA and dimethylated arsenoribose based arsenolipids both can transform to AB via intermediates previously identified in marine organisms. Further identification and characterization of As containing lipids is required. arsenic marine photosynthetic plants algae marine photosynthetic organisms salt marsh mangrove estuary inter-tidal south-east coast NSW
16	Pilot Project: Adaptive Strategies for Sustainable Rural Development Kuehnle, Renee 03 September 2013 (has links) The outport is in the midst of great change. Twenty years since the moratorium on cod fishing, the province of Newfoundland and Labrador is experiencing rapid economic development in another industrial resource boom. While some outports are growing, others continue to decline. This development is based on wealth gained through exploitation of non-renewable resources, and as such, is not sustainable. Investing a portion of these short-term gains into the development of sustainable alternates will improve opportunities and resources for future generations. Pilot Project proposes that latent outport phenomena may act as supporting structures for sustainable development. The project suggests methods of identifying and expanding sustainable outport phenomena. This analysis can be distilled into five strategic tools for testing, designing and implementing sustainable rural development. 1. Territorial Networks defines a diverse region, increasing individual community capacity and developing resilience by examining existing micro-regional community connections and designing new ones. 2. Community Stewardship encourages a re-organization of local social structures and informal governance initiatives by defining communication pathways and aligning stakeholder interests. 3. Temporal Alignment co-ordinates the events, services and opportunities over time, between communities, by creating flexible infrastructure for supporting temporary and seasonal outport needs. 4. Informal Economies develops new modes of production by blending traditional trade and barter markets with industrial production frameworks, providing economic sustenance in the outport. 5. Place-making constructs new institutions and landmarks with available resources, reorganizing the rural web of social, economic and ecological activity in the region. Newfoundland operates at the extremes. On one hand, rural folk culture has established small-scale, informal community structures; on the other, industrial mega-projects develop according to strict legislation, market pricing, and resource extraction. The proposed strategies find new links between these extremes. Tried and true vernacular development methods are paired with newly emerging technologies and ideas about the future. Rural areas in Newfoundland have historically been used as testing grounds for heavy-handed development ideas, often with severely adverse effects on communities. This project proposes a series of micro developments: the mobilization of existing resources with small capital investment, little risk, and immediate opportunities for implementation. Sustainable rural development is conceived as a practice, an aggregative change from within the community.

18	The impact of east coast fever on African homestead society in the Natal colony 1901-1910 Thabede, Mfanimpela Ishmael 08 1900 (has links) This dissertation looks at the impact of East Coast Fever on African homestead society in Natal in the period 1901-1910. The disease broke out in Natal at the beginning of 1904. With the realization that East Coast Fever was another lethal epizootic, the Natal Colonial Government introduced measures to control the spread of the disease and finally eradicate it. The campaign was, however, not successful. The disease thus spread throughout the colony and led to the loss of many cattle owned by Africans. By 1909 not more than four divisions in the colony remained free of the disease. The death of many cattle deprived Africans of the means of extensive cultivation, the source of income for the payment of rents and taxes, and Ilobolo. Many African males were forced to leave their homesteads for the towns and the mining sector in search of work. This eventually changed the nature of the homestead society. / History / M.A. (History) 636.2089684
