The Fossil Record Of Two-Phase Galaxy Assembly: Kinematics And Metallicities In The Nearest S0 Galaxy, J, A, Arnold, Aaron J. Romanowsky, J. P. Brodie, L. Chomiuk, L. R. Spitler, J. Strader, A. J. Benson, D. A. Forbes

Faculty Publications

We present a global analysis of kinematics and metallicity in the nearest S0 galaxy, NGC 3115, along with implications for its assembly history. The data include high-quality wide-field imaging from Suprime-Cam on the Subaru telescope, and multi-slit spectra of the field stars and globular clusters (GCs) obtained using Keck-DEIMOS/LRIS and Magellan-IMACS. Within two effective radii, the bulge (as traced by the stars and metal-rich GCs) is flattened and rotates rapidly (v/σ gsim 1.5). At larger radii, the rotation declines dramatically to v/σ ~ 0.7, but remains well aligned with the inner regions. The radial decrease in characteristic metallicity of both …

Star Clusters In M31: Old Clusters With Bar Kinematics, H. Morrison, N. Caldwell, R. P. Schiavon, E. Athanassoula, Aaron J. Romanowsky, P. Harding

Faculty Publications

We analyze our accurate kinematical data for the old clusters in the inner regions of M31. These velocities are based on high signal-to-noise Hectospec data. The data are well suited for analysis of M31's inner regions because we took particular care to correct for contamination by unresolved field stars from the disk and bulge in the fibers. The metal-poor clusters show kinematics that are compatible with a pressure-supported spheroid. The kinematics of metal-rich clusters, however, argue for a disk population. In particular the innermost region (inside 2 kpc) shows the kinematics of the x 2 family of bar periodic orbits, …

Evidence For Two Phases Of Galaxy Formation From Radial Trends In The Globular Cluster System Of Ngc 1407, D. A. Forbes, L. R. Spitler, J. Strader, Aaron J. Romanowsky, J. P. Brodie, C. Foster

Faculty Publications

Here we present the colours of individual globular clusters (GCs) around the massive elliptical galaxy NGC 1407 out to a projected galactocentric radius of 140 kpc or 17 galaxy effective radii (Re). Such data are a proxy for the halo metallicity. We find steep, and similar, metallicity gradients of ∼−0.4 dex dex−1 for both the blue (metal poor) and red (metal rich) GC subpopulations within 5–8.5 Re (40–70 kpc). At larger radii the mean GC colours (metallicity) are constant. A similar behaviour is seen in a wide-field study of M87's GC system, and in our own Galaxy. We interpret these …

The Dark Halo Of He Hydra I Galaxy Cluster: Core, Cusp, Cosmological? Dynamics Of Ngc 3311 And Its Globular Cluster System, T. Richtler, R. Salinas, I. Misgeld, M. Hilker, G.K. T. Hau, Aaron J. Romanowsky, Y. Schuberth, M. Spolaor

Faculty Publications

Context. Some galaxy clusters exhibit shallow or even cored dark matter density profiles in their central regions rather than the predicted steep or cuspy profiles, conflicting with the standard understanding of dark matter. NGC 3311 is the central cD galaxy of the Hydra I cluster (Abell 1060). Aims. We use globular clusters around NGC 3311, combined with kinematical data of the galaxy itself, to investigate the dark matter distribution in the central region of Hydra I. Methods. Radial velocities of 118 bright globular clusters, based on VLT/VIMOS mask spectroscopy, are used to calculate velocity dispersions which are well defined out …

Evaluation Of High-Frequency Oceanographic Signal In Grace Data: Implications For De-Aliasing, Jennifer A. Bonin, D. P. Chambers

Marine Science Faculty Publications

[1] The sub-monthly portion of a recent daily-resolution GRACE data set (ITG-Grace2010) is evaluated over the ocean by comparing with the high-frequency component of sea level variability measured by satellite altimetry. The current Atmosphere and Ocean De-aliasing (AOD) model used to remove the high-frequency non-tidal ocean mass variations in GRACE data processing is also assessed. We demonstrate that the OMCT-based AOD model does not adequately represent the true sub-monthly variability in non-tidal ocean mass variability, but that ITG-Grace2010 does. The differences are not small, and indicate that a new model, or a data set derived from sub-monthly GRACE information, should …

Enso-Correlated Fluctuations In Ocean Bottom Pressure And Wind-Stress Curl In The North Pacific, D. P. Chambers

Marine Science Faculty Publications

We examine the output of an ocean model forced by ECMWF winds to study the theoretical relationship between wind-induced changes in ocean bottom pressure in the North Pacific between 1992 until 2010 and ENSO. Our analysis indicates that while there are significant fluctuations correlated with some El Niño and La Niña events, the correlation is still relatively low. Moreover, the ENSO-correlated variability explains only 50 % of the non-seasonal, low-frequency variance. There are significant residual fluctuations in both wind-stress curl and ocean bottom pressure in the region with periods of 4-years and longer. One such fluctuation began in late 2002 …

Hot Crimes: A Study In Excess, Steven P. Grossman

All Faculty Scholarship

Societies appear to be subject, every now and then, to periods of moral panic. . . . [I]ts nature is presented in a stylized and stereotypical fashion by the mass media; the moral barricades are manned by editors, bishops, politicians and other right thinking people; socially accredited experts pronounce their diagnoses and solutions; ways of coping are evolved or (more often) restored to; . . . sometimes the panic passes over and is forgotten . . . at other times it has more serious and long-lasting repercussions and might produce such as those in legal and social policy or even …

An Equity-Based, Multilateral Approach For Sourcing Income Among Nations, Fred B. Brown

All Faculty Scholarship

The source of income rules used in the United States and elsewhere in large part establish the contours of tax jurisdiction exercised by countries. The source rules play a vital role in the foreign tax credit system applicable to U.S. persons with foreign investment or business activities. The source rules also play a central role in the United States’ exercise of source taxation over foreign persons with U.S. businesses or investments. Other countries likewise use source rules or their equivalent in applying foreign tax credit or territorial systems to their residents and exercising source taxation over nonresidents.

The current approach …

Racial Redistricting In A Post-Racial World, Gilda R. Daniels

All Faculty Scholarship

The 2011 redistricting will provide some interesting challenges for minority voting rights. How can we preserve minority electoral opportunities and gains in the wake of Bartlett v. Strickland and Georgia v. Ashcroft? What is the impact on future voting rights litigation and are coalition district claims viable as an opportunity to continue the electoral gains made since the passage of the Voting Rights Act? Are majority-minority districts safe from legislative backsliding? The Supreme Court's construed admonitions against race-conscious redistricting in recent cases may become cautionary tales. This Article discusses the central role the Voting Rights Act should play in preserving …

Overcoming Under-Compensation And Under-Deterrence In Intentional Tort Cases: Are Statutory Multiple Damages The Best Remedy?, Stephen J. Shapiro

All Faculty Scholarship

This Article advocates that states' statutes make greater and more systematic use of multiple damages by extending them to a much broader range of intentional, wrongful conduct. Part II of this Article will explain why extra-compensatory relief is called for when tortious conduct is intentional or malicious. Part III will compare punitive damages, attorney fees, and treble or other multiple damages as possible sources of additional relief. Part IV will focus on multiple damages. The Article will examine the range of existing state statutes and discuss why and how those statutes might be extended to a broader range of wrongful …

Comparative Deterrence From Private Enforcement And Criminal Enforcement Of The U.S. Antitrust Laws, Robert H. Lande, Joshua P. Davis

All Faculty Scholarship

This article shows that private enforcement of the U. S. antitrust laws-which usually is derided as essentially worthless-serves as a more important deterrent of anticompetitive behavior than the most esteemed antitrust program in the world, criminal enforcement by the Antitrust Division of the U.S. Department of Justice.

The debate over the value of private antitrust enforcement long has been heavy with self-serving assertions by powerful economic interests, but light on factual evidence. To help fill this void we have been conducting research for several years on a variety of empirical topics. This article develops and then explores the implications of …

The American "Rule": Assuring The Lion His Share, James Maxeiner

All Faculty Scholarship

Court costs in American civil procedure are allocated to the loser (“loser pays”) as elsewhere in the world. When American civil procedure took shape in the 1840s, American lawyers thought that losing parties ought to indemnify winning parties against all expenses of lawsuits. Yet today, attorneys’ fees – the lion’s share of expenses in the words of the General Report – are not allocated this way. By practice – and not by legal rule – attorneys’ fees fall on the parties that incur them. Those fees are not set by statute or court decision, but by agreement between parties and …

Civilizing American Civil Justice: International Insights, James Maxeiner, Gyooho Lee, Armin Weber

All Faculty Scholarship

In 1776, when Americans declared independence from Britain, they also declared their rights. Their declarations of rights count “open courts” as among the best means for constitutional development. Open courts should secure to every man, without regard to wealth, a just remedy for every wrong suffered, according to the law of the land, by fair and speedy procedure.

Since 1776 Americans have invested heavily in creating open courts. They have been disappointed by returns that fall “far short of perfection” (Maurice Rosenberg). They have found reform to be an “unending effort to perfect the imperfect” (Jay Tidmarsh).

That Americans have …

Harsh Parenting And Encouragement From Parents During Childhood: Long-Term Effects On Well-Being, Mental Health, And Major Illness, Ahmed Alkhalaf

Other Faculty of Science and Engineering Theses

This thesis examines long-term, negative consequences of various behaviours characteristic of negative parenting styles, specifically verbal maltreatment (insulting children), physical maltreatment (beating or hitting children), and lack of encouragement. Psychological scales were employed to explore the relationship of each of these factors to mental and physical health in adults. As a part of this research, a new questionnaire, the Arabic Parenting Style Questionnaire (APSQ), was developed and compared with existing measures. Seven separate studies were conducted with Saudi Arabian participants in order to investigate the questions put forth in this thesis. To explore the impact of harsh parenting and emotional …

Life Cycle Assessment Of Flax Fibres, Nilmini Pj Dissanayake

Other Faculty of Science and Engineering Theses

This thesis aims to investigate the sustainability of bast fibres specifically flax fibres as the reinforcement for polymer matrix composites (referenced to glass fibres) by undertaking a quantitative Life Cycle Assessment using the eight environmental impact classification factors of global warming, acidification, eutrophication, human toxicity, aquatic toxicity, ozone depletion, photochemical oxidants creation and non-renewable/abiotic resource depletion. A data set was compiled from numerous literature sources to complete the Life Cycle Inventory for the production of flax fibres. Three scenarios were studied for the production of either flax sliver (pre-spun fibre) or yarn (post-spun fibre): low (no-till combined with warm water …

The Ecotoxicology Of Engineered Nanoparticles To Freshwater Fish, Benjamin John Shaw

Other Faculty of Science and Engineering Theses

The use of nanoscale materials is growing exponentially, but there are also concerns about the environmental hazard to aquatic biota. Metal-containing engineered nanoparticles (NPs) are an important group of these new materials, and whilst there are undoubtedly a plethora of beneficial uses for these NPs, it is essential that an appropriate risk assessment is carried out in order to protect the environment and human health, with the consumption of contaminated fish a distinct possibility. The current study aimed to assess the bioavailability, uptake and toxicological effects of two metal-NPs (TiO2 NPs and Cu-NPs) to fish from both dietary and waterborne …

New Statistical Methods To Derive Functional Connectivity From Multiple Spike Trains, Mohammad Shahed Masud

Other Faculty of Science and Engineering Theses

Analysis of functional connectivity of simultaneously recorded multiple spike trains is one of the major issues in the neuroscience. The progress of the statistical methods to the analysis of functional connectivity of multiple spike trains is relatively slow. In this thesis two statistical techniques are presented to the analysis of functional connectivity of multiple spike trains. The first method is known as the modified correlation grid (MCG). This method is based on the calculation of cross-correlation function of all possible pair-wise spike trains. The second technique is known as the Cox method. This method is based on the modulated renewal …

Political Discourses Of Idealised Masculinity: The Risk Management Of Male Prisoners Through Work, Education And Family Transitions, Helen Mcfarlane

Other Faculty of Arts, Humanities and Business Theses

This thesis focuses upon the new rehabilitation of male prisoners within the context of idealised masculinity. Through the discourse analysis of written policy documents, this work addresses two fundamental questions: How is idealised masculinity constituted within political discourse and how does idealised masculinity influence the formulation of prison rehabilitation programmes? Idealised masculinity is defined as the heterosexual breadwinning role attributed to men as workers and providers for the family. It is this that is articulated within political discourses as a technique of government by which to reduce re-offending amongst the male prisoner population. Within the Foucauldian analysis of governmentality and …

Extreme Wave Loading On Offshore Wave Energy Devices Using Cfd, Jan Westphalen

Other Faculty of Science and Engineering Theses

Two commercial Navier-Stokes solvers are applied to wave-wave and wave-structure interaction problems leading to the final application of simulating a single float of the wave energy converter (WEC) Manchester Bobber in extreme waves and a fixed section of the Pelamis in regular waves. First the two software packages CFX and STAR CCM+ are validated against measured results from physical tank tests concerning the interaction of 3 non-linear focused wave groups of different steepness (Ning et al. 2007). The agreement for all of these cases is very good and could even be improved from first order to second order wave setup …

Tracking Tourists: Mobility, Experiences And The Supply-Demand Gap In A Swedish Mountain Resort, Bo Svensson, Robert Pettersson, Ingrid Zakrisson

Journal of Tourism Consumption and Practice

This study focuses on method development in the areas of visitor and experience tracking. It is about understanding experiences in a time-spatial framework made up by visits to a particular destination. These issues were identified as central for destination stakeholders in their attempts at meeting or exceeding visitor expectations at their destination. Development of methods here thus aims at supporting producers in generating such knowledge. The approach that emerged was to track and measure tourism experiences with the help of Global Positioning System (GPS) technology, follow-up surveys and in-depth interviews. The empirical findings are from a case study of the …

Modelling Coarse-Grained Beach Profile Evolution, Mohamad Hidayat Jamal

Other Faculty of Science and Engineering Theses

Coarse-grained beaches are particularly prevalent in the UK, composed of accumulations of either gravel, or mixed sand and gravel sediments. The aim of the work presented in this thesis is to improve capabilities for predicting coarse-grained beach 2D profile development. In particular, the effects of infiltration and sediment sorting are considered. In this study, the public domain numerical model, XBeach (v12) is developed further. This model was initially developed for studying sandy environments especially for the case of dune erosion. Here, the model is modified to enhance its capability to predict beach profile change on coarse-grained beaches. Improvements include: use …

Pyramidal Cell Diversity In The Rat Prefrontal Cortex: Electrophysiology, Dopamine Modulation And Morphology, Ullrich Bartsch

Other Faculty of Science and Engineering Theses

The prefrontal cortex (PFC) is critically involved in many higher cognitive functions such as goaldirected behaviour, affective behaviour and especially working memory. In vivo extracellular recordings of PFC neural activity during working memory tasks show high variety in observed spiking patterns. These complex dynamics are critically shaped by intrinsic, synaptic and structural parameters of respective prefrontal networks. Moreover, dopamine (DA) is crucial for correct functioning of the PFC during working memory tasks. DA modulates a number of synaptic and intrinsic biophysical properties of single neurons, in particular deep layer pyramidal cells, which represent the major output neurons of the PFC. …

Necessity, Possibility And The Search For Counterexamples In Human Reasoning, Sylvia Mary Parnell Serpell

Other Faculty of Science and Engineering Theses

Abstract Necessity, Possibility and the Search for Counterexamples in Human Reasoning Sylvia Mary Parnell Serpell This thesis presents a series of experiments where endorsement rates, latencies and measures of cognitive ability were collected, to investigate the extent to which people search for counterexamples under necessity instructions, and alternative models under possibility instructions. The research was motivated by a syllogistic reasoning study carried out by Evans, Handley, Harper, and Johnson-Laird (1999), and predictions were derived from mental model theory (Johnson-Laird, 1983; Johnson-Laird & Byrne, 1991). With regard to the endorsement rate data: Experiment 1 failed to find evidence that a search …

Population Structuring And Dispersal In The Highly Pelagic Leach's Storm-Petrel: Implications For The Eu Population, Anthony William James Bicknell

Other Faculty of Science and Engineering Theses

Dispersal is a fundamental process that shapes many aspects of population ecology and evolution. Dramatic local population declines brought about by anthropogenic-driven changes to ecological processes are unfortunately becoming ubiquitous and increasing the urgency to understand dispersal behaviour in many species. For species where direct methods of tracking movement and dispersal are unsuitable, other indirect methods need to be employed to understand and characterise these behaviours. The steep population decline, due to predation, at the largest EU population of Leach’s storm-petrels Oceanodroma leucorhoa (St Kilda, Scotland), and the potential part immigrant birds have in buffering this threat, highlighted the need …
