Market Power Without A Large Market Share: The Role Of Imperfect Information And Other “Consumer Protection” Market Failures, Robert H. Lande

All Faculty Scholarship

There are two very different sources of market power in antitrust cases. The first is traditional market share-based market power. Market power in antitrust cases also can come from deception, significantly imperfect or asymmetric information, or other types of market failures that usually are associated with consumer protection violations.

When these “consumer protection” market failures are present in antitrust cases, market power can arise even if no firm has a market share large enough for a finding of traditional market share based market power. However, instead of traditional end-use consumers being harmed, the direct victims are businesses.

The “consumer protection” …

Policy And Methods: Choices For Legislatures, James Maxeiner

All Faculty Scholarship

The legal methods through which one adopts and implements policy decisions profoundly affect the compatibility of policy implementation with democratic legitimacy and legal certainty of the rule of law. Indeed, the choice of legal methods can be as important as the formulation of the policy itself. While a good choice of methods will not heal a bad policy, it can help assure that a less-than-perfect choice of policy can be more forcefully realized than otherwise, it can also help improve the policy choices made and help protect democratic legitimacy and the rule of law. While deficiencies in legislation or in …

Identification Of Factors In Road Accidents Through In-Depth Accident Analysis, Mouyid B. Islam, Kunnawee Kanitpong

CUTR Faculty Journal Publications

The rising trend of motorization and improving socio-economic status of Thai people directly influences the aggravating road safety situation with fatalities and permanently disabled injuries of about 130,000 and 500,000 respectively over the past decades. An estimated annual cost from road crashes amounts to about US$2,500 million, 3.4 percent of Gross National Product (GNP), undoubtedly inflicts Thailand with a burning public health concern in the South East Asian region. This paper addresses an in-depth study through crash investigation and reconstruction which has not yet been practised in Thailand to identify the contributory factors in road crashes by the concerned authorities. …

Post-Traumatic Stress Disorder Following Stroke And Its Dispositional Risk Factors: A Cross-Cultural Study Between British And Chinese, Xu Wang

Methods: Four focus group discussions in Britain and China were conducted for study 1. Study 2 was a prospective longitudinal design in which 90 British patients were recruited and assessed approximately 1.5 and 4 months after stroke using a battery of instruments. Study 3 was a …

Doing Policing : An Inquiry Into The Rhetorical And Argumentative Skills Of The Police, Nicholas John Lynn

Other Faculty of Science and Engineering Theses

This thesis examines the spoken and written discourse of uniformed British police officers. Utilising a rhetorical and discursive analysis, the study considers firstly how officers use their considerable powers of discretion to deal informally with crime and criminal incidents. Focusing on a form of discretion that the police refer to as cuffing, two specific discursive practices were identified as being used by police to informally resolve crime: these were the giving of suitable advice and the that's civil device. The second part of the study was concerned with the formal prosecution process and how officers construct prosecution case files. Specifically, …

Locomotor Patterns And Persistent Activity In Self-Organizing Neural Models, Thomas Henry Cooke

Other Faculty of Science and Engineering Theses

The thesis investigates principles of self-organization that may account for the observed structure and behaviour of neural networks that generate locomotor behaviour and complex spatiotemporal patterns such as spiral waves, metastable states and persistent activity. This relates to the general neuroscience problem of finding the correspondence between the structure of neural networks and their function. This question is both extremely important and difficult to answer because the structure of a neural network defines a specific type of neural dynamics which underpins some function of the neural system and also influences the structure and parameters of the network including connection strengths. …

Biodiversity And Ecosystem Processes In The Strandline: The Role Of Species Identity, Diversity, Interactions And Body Size, Sally Jane Marsh

Other Faculty of Science and Engineering Theses

In the current climate of biodiversity loss how species diversity and ecosystem process are linked is, arguably, one of the most pressing issues and greatest challenges currently facing the scientific community. Previous studies suggest that there is no universal trajectory for the relationship between diversity and ecosystem processes, the pattern depends largely on species identity and their interactions. Furthermore, the effect of reduced diversity on ecosystem process in multi-trophic assemblages is both understudied and poorly understood. Consequently, the overall aim of the present study was to investigate the role of species identity, diversity and interactions in determining ecosystem processes using …

Measuring And Modelling Of Cross-Shore Sediment Transport And Profile Evolution On Natural Beaches, Jonathan Tinker

Other Faculty of Science and Engineering Theses

Cross-shore sediment transport is the dominant process causing beach profile evolution. The ability to model cross-shore sediment transport allows prediction of the future beach state be made. Due to a balance between opposing mechanisms, cross-shore sediment transport is difficult to predict. One route to make these predictions is with the development of measurement based parameterisation. This study builds on previousp arameterisationtsh at have relatedc ross-shorev elocity moment (predictorso f suspendeds edimentt ransporta ccordingt o the energeticsa pproacht o sediment transport)t o normalisedd epth( a proxy of cross-shorep osition),t o presenta new shapef unction parameterisationT. he presentp arameterisatiohna s beend evelopedf …

Mathematical Modelling Of Shoreline Evolution Under Climate Change, Anna Zacharioudaki

Other Faculty of Science and Engineering Theses

This study focuses on the impact of potential changes in the wind-wave climate on shoreline change. The `one-line' model for medium to long-term prediction of coastline evolution is employed. New analytical and numerical solutions of this important model are described. Specifically: 1) original semi-analytical solutions are derived that relax the unrealistic assumption of existing analytical work that a constant wave condition drives shoreline change and, 2) a more general form of the one-line model is solved with a novel application of the `Method of Lines'. Model input consists of 30-year nearshore wave climate scenarios, corresponding to the `present' (1961-1990) and …

Mathematical Modelling Of Hepatopancreatic Digestive Cell Of The Blue Mussel, Allan Mcveigh

Other Faculty of Science and Engineering Theses

The lysosomal system of the hepatopancreatic digestive cell of the mussel (Mytilus sp.) is critical in intracellular food degradation, toxic responses and internal cellular turnover. Mathematical and numerical models are developed to simulate the responses of this system to varying conditions, dietary and toxicological. The model evolution encompasses: inclusion of glycogen/lipid storage forms; extrapolation to include nitrogen metabolism; development of rate of endocytosis and food signal; increased functionality of endo/lysosomes; shift to protein/carbohydrate/lipid based model; and the incorporation of the cost of normal Sanction and replacement of damaged components. Control is asserted through control of cytosolic concentrations: the intial assumption …

Predation By Crabs On Rocky Shores In North-East Atlantic, Ana Catarina Ferreira Da Silva

Other Faculty of Science and Engineering Theses

Highly mobile predators are known to have an important influence on shallow-water habitats. There is, however, little information about the role of crabs on the ecology of rocky shores. Here I examine the extent and consequences of predation by crabs on shores in the North-East Atlantic. The specific aims of this thesis are to: investigate spatial variation in use of the intertidal by crabs along a horizontal gradient of exposure to wave action and a vertical gradient of tidal elevation; assess their use of the intertidal as a feeding area by examining stomach content composition; examine the extent of connectivity …

Victims And Villains: Subject Positioning In Discursive Reconstructions Of Sexual Harassment, Sarah Jane Clarke

Other Faculty of Science and Engineering Theses

This thesis is a feminist informed, discursive research project. Three studies are presented, each designed to explore reconstructions of sexual harassment incidents. The first and second studies were based upon a corpus of interview data, generated specifically for the research project. The author interviewed six women and encouraged detailed discussion about sexual harassment. The third study was conducted utilising media data. The data includes an initial allegation and description of an incident of sexual harassment, in the form of a magazine article, and a collection of published responses written by journalists, academics and members of the public. The data were …

Computational And Psycho-Physiological Investigations Of Musical Emotions, Eduardo Coutinho

Other Faculty of Science and Engineering Theses

The ability of music to stir human emotions is a well known fact (Gabrielsson & Lindstrom. 2001). However, the manner in which music contributes to those experiences remains obscured. One of the main reasons is the large number of syndromes that characterise emotional experiences. Another is their subjective nature: musical emotions can be affected by memories, individual preferences and attitudes, among other factors (Scherer & Zentner, 2001). But can the same music induce similar affective experiences in all listeners, somehow independently of acculturation or personal bias? A considerable corpus of literature has consistently reported that listeners agree rather strongly about …

Biomediation Of Turbulence And Suspended Sediment Characteristics In Marsh Surface Flows - The Influence Of Spartina Anglica, George W. Graham

Other Faculty of Science and Engineering Theses

Laboratory experimentation in a large aimular flume (radius 3 m, channel width and water depth 0.4 m) has been conducted using a geometrically and dynamically similar Spariina anglica mimic (canopy height 0.21 m, stem density 1000 stems m~^) to investigate the influence of submerged Spartina on hydrodynamics under unidirectional currents {Uh = 0.2 m s~*) and the impact upon the dynamics of suspended cohesive sediments near the bed within the canopy. The vertical distribution of canopy biomass strongly influences vertical profiles of time-averaged velocity and turbulent quantities. An inflected velocity profile is observed in the region 0.79 < z/h < 0.9 which generates shear, T K E and Reynolds Stress peaks within vicinity of the canopy top. In this region T K E peaks at 15 times the levels observed in un-vegetated experiments. Flows at the canopy top are strongly intermittent with extremely efficient downward momentum transfer, uf] and ufz (stream-wise and vertical zero-mean fluctuating velocity) skewness are 0.5 and -0.5 indicating the presence of intermittent downward penetrating gusts. Near the bed (0 < z/h < 0.3) mean flow velocities are reduced by 88 - 90% in comparison to un-vegetated flows but turbulence intensities are strongly augmented by wake shedding from vegetative elements. TKE in this region is approximately equal to that in un-vegetated flows. Novel field observations in a low energ>', estuarine fringing …

Relative Quantitation Of Peptides By Inductively Coupled Plasma Mass Spectrometry, Pritesh Patel

Other Faculty of Science and Engineering Theses

Currently, the detection/quantitation of biomolecules using Inductively Coupled Plasma Mass Spectrometry (ICR-MS) is focused on heteroatom containing (e.g. S. P, Se, Cu) compounds. This limits the scope of ICP-MS as a routine analytical tool in the bioanalytical sciences. To increase this scope novel strategies to incorporate elemental labels have been developed. Chemical derivatisation is one such strategy. Cyclic diethylenetriaminepentaacetic acid anhydride (cDTPA), a bifunctional chelating agent (BFCA), is reacted with N-terminal amines and is subsequently chelated with trivalent metals. This allows the detection of peptides that contained no heteroatom using liquid chromatography (LC)-ICP-MS. The derivatisation efficiency, optimised using LC-UV/vis detection, …

Biogeochemical Controls On The Corrosion And Fate Of Depleted Uranium, Stephanie Handley-Sidhu

Other Faculty of Science and Engineering Theses

Depleted uranium (DU) is a by-product of the nuclear fuel industry and is used in antitank penetrators due to its high density, self-sharpening and pyrophoric properties. Military activities have left a legacy of DU waste in terrestrial and marine environments and presently there are no clean up procedures in place. In order to understand the fate of this DU, long term (500 days) microcosm experiments simulating key environments have been carried out for the first time to investigate the mechanisms and rates of DU corrosion as a function of the biogeochemical and environmental conditions. The corrosion of DU was investigated …

The Resistance Of An Established Profession Towards An Emergent Occupation, Richard William Goslin

Other Faculty of Arts, Humanities and Business Theses

This study examines the relationship between orthopaedic and podiatric surgeons which has formed since the NHS reforms of the 1990s facilitated the establishment of podiatric surgery as a mainstream health-care service. Relations between these two disciplines are considered against the traditional background of dominance of health-care by the medical profession. The study seeks to understand the resistance shown towards podiatric surgery by orthopaedic surgeons and to determine if there is a willingness among orthopaedic and podiatric surgeons, respectively, to develop a more satisfactory working relationship. Two methods of data collection were employed to gather information on the views of orthopaedic …

Stewards Of The Earth? : A Study Of Teenagers' Pro-Environmental Attitudes And Lifestyles In Devon, Uk And Malaga, Spain, Jennie Winter

Other Faculty of Arts, Humanities and Business Theses

Individual responses to sustainability are recognised as fundamental to progressing the sustainable development agenda. In order to raise awareness and support for sustainability, concerted programmes of Education for Sustainable Development (ESD) have been promoted and ESD is now a core element of educational curricula in many countries, particularly in the developed world. One group of particular interest to educators and policy makers is teenagers. Their engagement with sustainability issues, both in rhetorical and participatory terms, is considered essential to both the short and long term infusion of sustainability into public consciousness. However, despite continuing endeavours to involve teenagers in the …

Chasing The Vote : Developments In The Ways Political Parties Conduct Election Campaigns, Timothy Andrew Jones

Other Faculty of Arts, Humanities and Business Theses

The methods political parties use to engage the electorate during election campaigns undergo a continual process of re-evaluation and modification; this study seeks to further understanding of this process by proposing the concept of a toolkit of techniques from which those who plan campaigns make selections, based on the type of campaign and the resources they have available. Using data gathered from interviews of experienced campaigners, a case study from the 2007 local elections, and the author's own experience as a political campaigner, the development of campaigning is considered from the perspective of the candidate and campaigner 'on the ground'. …

The Unknown That What I Say Is Not What I Mean, Tomasz Wendland

Other Faculty of Arts, Humanities and Business Theses

This work is a confession in front of both myself and the one who reads my words and looks at my images. It is unusual to confess with images, because they uncover what we hide with words. Through a body of visual arts practice completed between 2000 and 2007 and its accompanying written commentary and critical account, I have attempted to address notions of the "unknown". In this enquiry, the "unknown" is understood to be hidden between "what I say and what I mean", where, for example, consciousness has no access between drawing and intention, or between prediction and intuition. …

Musicology And Mediation: An Examination Of The Cultural Materialisms Of Raymond Williams And Pierre Bourdieu In Relation To The Fields Of Contemporary Music And Musicology, With A Case Study Of Arvo Part And Ecm, Tom Begbie

Other Faculty of Arts, Humanities and Business Theses

This thesis examines the usefulness of the work of Pierre Bourdieu and Raymond Williams for discussions of material mediation in musicology. In part I, I focus on Bourdieu's discussions of cultural production as set out in The Rules of Art and "The Field of Cultural Production", and reconstruct the terms of Williams's late theoretical project. In establishing the terms of these projects, I draw a parallel between their attempts to materialize the categories of Marx's superstructure - noting in Williams's subsequent use of a revised Marxist production paradigm a proximity to the work of Adorno - before noting the differences …

Speaking Of Gender, Language And Identity: Writing The Personal, Barbara Bridger

Other Faculty of Arts, Humanities and Business Theses

This thesis features a range of texts that exemplify my practice. They include experimental prose, poetry, hybrid forms of writing that merge theory and practice, and scripts for live performance and digital film. To these examples I apply an autobiographical writing method, one that simultaneously reflects and creates, in an enquiry designed to uncover the detail and complexity of my writing motivation through a discursive account of its context. In a process that acknowledges the centrality of language to the construction of female identity, I begin by exploring the importance of autobiography to both my writing and this thesis. Next …

Policing Partnerships: An Investigation Into The Police Response To Partnership Working In The Wake Of The 1998 Crime And Disorder Act, Stuart David Lander

Other Faculty of Arts, Humanities and Business Theses

This thesis is based upon empirical research, which explores how the police service in one Constabulary area has accommodated the mandate to work in crime prevention partnerships with other agencies, following the implementation of the 1998 Crime and Disorder Act. The focus is specifically upon crime and disorder reduction partnerships (CDRPs). The research is based upon a multi-method research design. It draws most heavily upon data obtained from semi-structured interviews with police officers holding varying experiences of crime prevention partnership working across one Constabulary area. It also analyses official documents, and draws upon the results of a short survey combined …

Other Faculty of Arts, Humanities and Business Theses

The purpose of this research was to produce a model to predict levels of homelessness within a local authority area. The research considered data on a wide range of issues embedded in theory and supported by the literature as being common precedents to homelessness. Areas of investigation included housing, migration, poverty, deinstitutionalisation. ethnicity, poor health, drug abuse, sex and age, relationship breakdown as well as general variables profiling the area. Data was compared both to the numbers of homeless decisions made within a local authority area as well as the numbers of those decisions that resulted in the full homeless …

Investigation Into Land-Use Change In Two Contrasting Areas In The Nile Delta, Egypt, Rawad S. Echtaie

Other Faculty of Arts, Humanities and Business Theses

Understanding land-use change in developing countries, particularly those situated in environmentally vulnerable and and semi-arid zones, is crucial given the considerable pressures arising due to rapid population growth, climate change and desertification. The purpose of this research was to investigate the main drivers affecting land-use change in the eastern part of the Nile Delta, Egypt in the last two decades. Two contrasting cities in the region were selected for detailed analysis. Almansourah is an ancient settlement relatively close to the Damietta branch of the Nile whereas Alzaqazig is a recent development and the surrounding area was reclaimed from the desert. …

A Sociological Critique Of 'Grand Narratives' In The History Of Hospice And Palliative Care, Mary Curtis

Other Faculty of Arts, Humanities and Business Theses

This thesis is a sociological history and critique of hospice and palliative care: their goals, narratives, and social, clinical and ethical practices. Hospice developed in Britain as a result of and challenge to interventionist biomedicine within hospitals where dying came to be viewed as medical failure. From the mid twentieth century hospice was promoted as a 'philosophy of care' that had at its locus a concept of 'whole' person family care for people who are dying. For the first tune patients and then: relatives became the unit of care. Henceforth, hospice established for itself three major 'goals'; (1) hoUstic symptom …
