Weathering Extremes: Climate, Colonialism, And Indigenous Resistance In The Dutch Atlantic, Nicholas Cunigan Jan 2013

Weathering Extremes: Climate, Colonialism, And Indigenous Resistance In The Dutch Atlantic, Nicholas Cunigan

University Faculty Publications and Creative Works

Weathering Extremes demonstrates how seventeenth-century climate changes mingled with cultural, social, economic, agro-ecological, and geopolitical forces to catalyze three simultaneous, though geographically disparate, indigenous resistance movements between 1636 and 1645. In Brazil, Curaçao, and the Hudson Valley, indigenous peoples deployed violent and non-violent means of resistance to confront the Dutch West India Company. This broadly interdisciplinary project utilizes natural proxy sources such as pollen samples, ice cores, and tree rings in conjunction with ethnohistorical and Dutch archival sources to reconstruct how early seventeenth-century extreme weather events catalyzed these movements. El Niño-Southern Oscillation (ENSO) events, volcanic eruptions, and reduced sunspot activity …

Inorganic Hydrogeochemical Responses To Fires In Wetland Sediments On The Swan Coastal Plain, Western Australia, David Blake Jan 2013

Inorganic Hydrogeochemical Responses To Fires In Wetland Sediments On The Swan Coastal Plain, Western Australia, David Blake

Theses: Doctorates and Masters

In the past decade the wetlands of the Swan Coastal Plain (SCP) region of Western Australia have been subject to increasing fire frequency and intensity. Whilst wetland sediment fires (also known as peat fires) on the SCP are not new phenomena, the increased frequency, duration and extent of combustion have been concomitant with an increase in urbanisation and reduction in average annual rainfall for the region. This has led to a decrease in ground- and surface-water levels which, in turn, has increased the susceptibility of the wetland sediments to ignition and combustion events. Increased wetland fire severity has resulted in …

Relative Sensitivity Of Two Marine Bivalves For Detection Of Genotoxic And Cytotoxic Effects: A Field Assessment In The Tamar Estuary, South West England., Lorna J. Dallas, Victoria V. Cheung, Andrew S. Fisher, Awadhesh N. Jha

School of Geography, Earth and Environmental Sciences

The input of anthropogenic contaminants to the aquatic environment is a major concern for scientists, regulators and the public. This is especially relevant in areas such as the Tamar valley in SW England, which has a legacy of contamination from industrial activity in the nineteenth and twentieth centuries. Following on from previous laboratory validation studies, this study aimed to assess the relationship between genotoxic and cytotoxic responses and heavy metal concentrations in two bivalve species sampled from locations along the Tamar estuary. Adult cockles, Cerastoderma edule, and blue mussels, Mytilus edulis, were sampled from five locations in the Tamar and …

A Fimh Inhibitor Prevents Acute Bladder Infection And Treats Chronic Cystitis Caused By Multidrug-Resistant Uropathogenic Escherichia Coli St131., Makrina Totsika, Maria Kostakioti, Thomas J. Hannan, Mathew Upton, Scott A. Beatson, James W. Janetka, Scott J. Hultgren, Mark A. Schembri

School of Biomedical Sciences

BACKGROUND: Escherichia coli O25b:H4-ST131 represents a predominant clone of multidrug-resistant uropathogens currently circulating worldwide in hospitals and the community. Urinary tract infections (UTIs) caused by E. coli ST131 are typically associated with limited treatment options and are often recurrent. METHODS: Using established mouse models of acute and chronic UTI, we mapped the pathogenic trajectory of the reference E. coli ST131 UTI isolate, strain EC958. RESULTS: We demonstrated that E. coli EC958 can invade bladder epithelial cells and form intracellular bacterial communities early during acute UTI. Moreover, E. coli EC958 persisted in the bladder and established chronic UTI. Prophylactic antibiotic administration …

The Pornographics Of Japanese Negrophilia, Jd Mackintosh Jan 2013

The Pornographics Of Japanese Negrophilia, Jd Mackintosh

School of Law, Humanities and Social Sciences

In 1974, a bizarre story, ‘Jigoku ni ochita wakamonotachi’ (‘Young Men Fallen into Hell’), appeared in the Japanese homo magazine Adon. It described in pornographic detail the sado-masochistic torture of Japanese men captured and forced to perform in a black circus troupe in American-occupied Japan. ‘Jigoku’ was unremarkable except that, in its stylised ‘pornographics’, it uniquely – for the homo imagination – configured sexual desire as a Japanese–black inter-racial intercourse. This article explores this imagination through a close reading of ‘Jigoku’. It traces a post-war ‘genealogy’ of blackness (Russell 2006), which finds affinity of meaning and value cutting across sub-cultural …

Site Fidelity And Localised Homing Behaviour In Three-Spined Sticklebacks (Gasterosteus Aculeatus), A. J.W. Ward, R. James, A. D.M. Wilson, M. M. Webster Jan 2013

Site Fidelity And Localised Homing Behaviour In Three-Spined Sticklebacks (Gasterosteus Aculeatus), A. J.W. Ward, R. James, A. D.M. Wilson, M. M. Webster

School of Biological and Marine Sciences

The ability of animals to disperse towards their original home range following displacement has been demonstrated in a number of species. However, little is known about the homing ability of three-spine sticklebacks (Gasterosteus aculeatus), an important model species in behavioural ecology. In addition, few studies have examined the role of social facilitation in relation to homing behaviour in fishes. We examined homing behaviour of sticklebacks displaced over distances of between 80 m and 160 m in land-drains with directional water flow. Fish were translocated from their original capture site, tagged and then released either in groups or solitarily. We performed …

Epibenthic Assessment Of A Renewable Tidal Energy Site, Emma V. Sheehan, Sarah C. Gall, Sophie L. Cousens, Martin J. Attrill Jan 2013

Epibenthic Assessment Of A Renewable Tidal Energy Site, Emma V. Sheehan, Sarah C. Gall, Sophie L. Cousens, Martin J. Attrill

School of Biological and Marine Sciences

Concern over global climate change as a result of fossil fuel use has resulted in energy production from renewable sources. Marine renewable energy devices provide clean electricity but can also cause physical disturbance to the local environment. There is a considerable paucity of ecological data at potential marine renewable energy sites that is needed to assess potential future impacts and allow optimal siting of devices. Here, we provide a baseline benthic survey for the Big Russel in Guernsey, UK, a potential site for tidal energy development. To assess the suitability of proposed sites for marine renewable energy in the Big …

Harmonizing Distributed Energy And The Endangered Species Act, J. B. Ruhl Jan 2013

Harmonizing Distributed Energy And The Endangered Species Act, J. B. Ruhl

San Diego Journal of Climate & Energy Law

This Article explores ways of harmonizing distributed energy and the ESA, a goal consistent with the national policy for renewable energy conservation. Several legal practitioners and scholars have identified the ESA as a potentially significant constraint on the siting and operation of wind power facilities. The ESA has also been identified as a potential barrier to renewable energy in general, as solar power, biomass, and ocean tide and wave facilities could have their own sets of impacts triggering ESA regulation. But most of this attention has been devoted to utility-scale renewable energy, with distributed energy largely ignored or perhaps assumed …

Climate Changes Disputes At The World Trade Organization: National Energy Policies And International Trade Liability, Nilmini Silva-Send Jan 2013

Climate Changes Disputes At The World Trade Organization: National Energy Policies And International Trade Liability, Nilmini Silva-Send

San Diego Journal of Climate & Energy Law

This Article draws attention to the different outcomes that may result when WTO law is applied to resolve climate related national energy policy disputes, signals this might send for national energy policies, and how a subtle effect of indirect state liability may arise. Several pending or unresolved complaints currently at the WTO are used to demonstrate these effects. The complaints include the greenhouse gas controversy, the wind energy subsidies complaint, and the feed-in tariffs complaint. The next section, Section II, presents the basic WTO obligations of the four countries involved in these complaints (Japan, Canada, USA, China), and ways that …

The Emergence Of Natural Gas And The Need For Cooperative Federalism To Address A Big "Fracking" Problem., Joshua P. Dennis Jan 2013

The Emergence Of Natural Gas And The Need For Cooperative Federalism To Address A Big "Fracking" Problem., Joshua P. Dennis

San Diego Journal of Climate & Energy Law

This Comment explores the recent emergence of natural gas production, the hydraulic fracturing process and briefly touches on the current regulatory system that oversees its operation. I then explain why the current regulatory system is insufficient to protect individuals and the environment from hydraulic fracturing. And lastly, I argue that a form of cooperative federalism is the best approach to regulate hydraulic fracturing.

The Texas Heart Institute Journal

Sudden cardiac death in athletes is a recurrent phenomenon at sporting events and during training. Recent studies have associated sudden cardiac death with such cardiovascular conditions as coronary artery anomalies, cardiomyopathies, and electrocardiographic abnormalities, most of which are screenable with modern imaging techniques. We recently inaugurated the Center for Coronary Artery Anomalies at the Texas Heart Institute, which is dedicated to preventing sudden cardiac death in the young and investigating coronary artery anomalies. There, we are conducting 2 cross-sectional studies intended to firmly establish and quantify, in a large group of individuals from a general population, risk factors for sudden …

The Texas Heart Institute Journal

The present study was undertaken to investigate, in an animal model, the relationship between sarcoplasmic reticulum Ca2+-ATPase (SERCA2a) activity, phospholamban phosphorylation, acylphosphatase activity, and hemodynamic changes that occur in the early phase of pressure overload. In 54 study-group pigs, weighing 40±5 kg each, an aortic stenosis was created with a band of umbilical tape tied around the aorta; 18 sham-operated pigs formed our control group. Eight animals (6 study and 2 control) were randomly assigned to each experimental time (0.5, 3, 6, 12, 24, 48, 72, 96, and 168 hr). All indices of left ventricular function declined significantly, with a …

Microfluidic Impedance-Metric Biosensor For Monitoring Carbon Nanotube-Induced Epithelial Permeability, Zhouchun Huang Jan 2013

Microfluidic Impedance-Metric Biosensor For Monitoring Carbon Nanotube-Induced Epithelial Permeability, Zhouchun Huang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Carbon nanomaterials, including carbon nanotubes (CNTs) gain increasing interest in commercial and biomedical applications. Adverse health effects of engineered CNTs may result from either direct exposure during production, inadvertent exposure during use of by-products, and/or release of these materials into the environment. Recent studies have shown that CNTs can induce cytotoxicity, apoptosis, DNA damage, and tumor formation in animals, suggesting their potential toxicity in humans. To address the current needs in developing in vitro cell assays for assessment of the adverse health effects of CNTs in lung respiratory, we have developed a microfluidic impedance-metric biosensor for investigation of multi-walled CNTs …

A Comparison Of Responses And Exteroceptive Stimuli As Time Markers, Adam E. Fox Jan 2013

A Comparison Of Responses And Exteroceptive Stimuli As Time Markers, Adam E. Fox

Graduate Theses, Dissertations, and Problem Reports (ETD)

Time markers are events that are predictive of when future events will occur. Different events can serve as time markers that initiate intervals in schedules of reinforcement. Pigeons were exposed to fixed-interval (FI) schedules in which the onset of the interval was signaled by the illumination of a key light, initiated by a peck to a lighted key, or a combination of both events. In these variations of fixed-interval schedules, food was delivered contingent on the first response after the interval elapsed. In Experiment 1, three pigeons were exposed to a multiple schedule. One component was a standard FI schedule; …

Stress And Obesity: Facilitation Of Neuroendocrine And Autonomic Nervous System Recovery From Stress While Eating Comfort Foods?, Paula R. Prentice Jan 2013

Stress And Obesity: Facilitation Of Neuroendocrine And Autonomic Nervous System Recovery From Stress While Eating Comfort Foods?, Paula R. Prentice

Graduate Theses, Dissertations, and Problem Reports (ETD)

Obesity and dysfunctional eating are prevalent and costly concerns in the United States and throughout the world (CDC, 2007; Mathus-Vliegen et al., 2008). Research into the etiology of these conditions points to problems regulating eating, particularly during times of stress. The animal literature suggests that eating during and following stress may lead to a more immediate physiological recovery from stress (e.g., Bulwalkda et al., 2001; Pecoraro et al., 2004). The present study was designed to test this phenomenon in humans; that is, to determine if eating a favorite food immediately after stress would lead to enhanced physiological recovery from stress; …

Coming Home: Servant-Leadership, Men, And The Road Back To One Another, Shann Ray Ferch Jan 2013

Coming Home: Servant-Leadership, Men, And The Road Back To One Another, Shann Ray Ferch

International Journal of Servant-Leadership

A primary reason for the general malaise and lack of leadership experienced by many in contemporary society coincides with a loss of the essence of what it means to live in and be developed by a real community, or to encounter what might be called a sense of home. In Greenleaf's terms, the true community is a result of servant-leaders working to meet the most ultimate needs of those with whom they come into contact. The result of meeting such needs is that others grow wiser, more free, more healthy, and more autonomous. In Greenleaf's conception, in a good community, …
