Evidence Of The Efficiency Of Index Options Markets, Lucy F. Ackert, Yisong S. Tian Jan 2000

Evidence Of The Efficiency Of Index Options Markets, Lucy F. Ackert, Yisong S. Tian

Faculty Articles

Index options have been one of the most successful of the many innovative financial instruments introduced over the last few decades, as their high trading volume indicates. Given their prominence, the pricing efficiency of these markets is of great importance. ; Detecting inefficient pricing, or mispricing, requires comparing a theoretically efficient price with prices of options traded in financial markets. One popular approach to deriving pricing relationships is based on a principle called no-arbitrage, which simply assumes that arbitrageurs enter the market and quickly eliminate mispricing if a profit opportunity without risk exists. However, in a well-functioning economy there is …

A Wide Field 90 Cm Vla Image Of The Galactic Center Region, Ted La Rosa, Namir E. Kassim, Joseph W. Lazlo, Scott B. Hyman

Faculty Articles

We present a wide-field, high dynamic range, high-resolution, long-wavelength (lambda = 90 cm) VLA image of the Galactic center region. The image is centered on Sgr A, covers an area of 4 degrees x 5 degrees with an angular resolution of 43 ", and has a rms sensitivity of approximate to 5 mJy beam-l. The image was constructed from archival (1989 and 1991) VLA data of Pedlar et al. and Anantharamaiah et al. using new three-dimensional image restoration techniques. These three-dimensional imaging techniques resolve the problem of non-coplanar baselines encountered at long wavelengths and yield distortion-free imaging of far-field sources …

Liability Issues Facing Online Businesses, David E. Shipley Jan 2000

Liability Issues Facing Online Businesses, David E. Shipley

Scholarly Works

Online businesses are confronted by a wide variety of liability issues covering almost the full range of the standard law school curriculum. The liability problems that face a small business in Vidalia, Georgia, which is selling Vidalia onion products at specialty stores, through print advertising, and by mail, do not go away when the business starts marketing through a Web site. In fact, there might be more exposure doing business online, and there are variations depending upon the nature of the business in question. For example, as discussed below, an Internet Service Provider ("ISP") like America Online has worries that …

Rethinking The Risk Of Defined Contribution Plans, Regina T. Jefferson Jan 2000

Rethinking The Risk Of Defined Contribution Plans, Regina T. Jefferson

Scholarly Articles

This article analyzes the risk of shortfall in the expected retirement benefits in defined contribution plans, as regulated by the Employee Retirement Income Security Act of 1974 (ERISA). The article compares and contrasts the allocation of investment risks between defined benefit and defined contribution plans. This article demonstrates that current pension law offers inadequate protection of the expected retirement benefit in defined contribution plans and proposes additional fiduciary, insurance, and funding protection for defined contribution plans.

Masculinity And Femininity: Origins And Implications (Chapter Two Of Growing Strong Daughters), Lisa Graham Mcminn Jan 2000

Masculinity And Femininity: Origins And Implications (Chapter Two Of Growing Strong Daughters), Lisa Graham Mcminn

Faculty Publications - Department of Sociology

Excerpt: "God could have made one sex, but he chose to create two distinct image-bearing creatures. Articulating conclusions about how women and men bear God's image differently is difficult, perhaps because we believe we must first figure out which differences to attribute to environment and which are knitted into our beings at conception."

Extending Literacy : Pupils' Interactions With Texts, With Particular Emphasis On The Use Of Non-Fiction Texts, Maureen Lewis Jan 2000

Extending Literacy : Pupils' Interactions With Texts, With Particular Emphasis On The Use Of Non-Fiction Texts, Maureen Lewis

Plymouth Institute of Education Theses

The submitted works explore how children use texts in the classroom and how they can be supported in becoming more effective readers and writers. Most of the work is based around pupil's use of non-fiction texts and provides case study examples of what happens when children engage in tasks which require their use. I argue that we can elaborate a model to describe the processes involved in such encounters. This proposed model is described and compared to earlier attempts to create a model of the process of interacting with non-fiction texts. It is further argued that specific strategies can be …

An Investigation Of Lower Secondary Pupils' Images Of Mathematics And Mathematicians, Susan Helen Picker Jan 2000

An Investigation Of Lower Secondary Pupils' Images Of Mathematics And Mathematicians, Susan Helen Picker

Plymouth Institute of Education Theses

This thesis reports on a three-part research project in which the images of mathematics and mathematicians held by lower secondary pupils were investigated. A survey tool which asked pupils to draw a picture of a mathematician at work, and which included a Likert-type scale and open-ended writing prompts, was designed and developed for use in an international study of pupils in five countries (n = 476). The results indicate that while some pupils hold stereotypical images in common, all pupils appear to know very little about mathematicians and the work they do. Mathematicians' invisibility to pupils of this age appears …

Trace Metal And Speciation Analysis Using Ion-Exchange And Energy Dispersive X-Ray Fluorescence Spectrometry, Elena Menendez-Alonso Jan 2000

Trace Metal And Speciation Analysis Using Ion-Exchange And Energy Dispersive X-Ray Fluorescence Spectrometry, Elena Menendez-Alonso

School of Geography, Earth and Environmental Sciences Theses

Studies have been carried out on specific ion-exchange (Dowex 50W-X8 and Dowex 1-X8) and chelation (Chelex-100) resins, in order to determine their physical and chemical characteristics, to understand and explain their limits of function and to optimise their use as substrates in trace metal and speciation measurement by EDXRF. Structural information was obtained by scanning electron microscopy and x-ray microanalysis showing a homogeneous distribution of functional groups and retained ions on both sectioned and whole resins. Particle size experiments performed on Dowex 50W-X8 (38 - 840 µm) showed that this parameter has no effect on the relationship between intensity of …

Microfaunal Investigation Of The Early Toarcian (Lower Jurassic) Extinction Event In N.W. Europe, Mark Donald Hylton Jan 2000

Microfaunal Investigation Of The Early Toarcian (Lower Jurassic) Extinction Event In N.W. Europe, Mark Donald Hylton

School of Geography, Earth and Environmental Sciences Theses

The Early Jurassic was a time of rapidly rising sea-level associated with the extensive spread of anoxic bottom waters. Sea-level rise across the Pliensbachian - Toarcian boundary culminated in the falciferum Zone of the Toarcian and is one of the best authenticated eustatic events in the Jurassic. This major transgressive pulse was marked by deepw ater marine sequencesa nd was associatedw ith the deposition of organic-rich shales. The development of anoxia coincides with a notable period of mass extinction of the marine fauna. High resolution sampling and study of the microfaunast hrough sequencesin N. W. Europe confirm that benthic foraminiferal. …

Sub-Surface Migration Of An Oil Pollutant Into Aquifers, Louise Ann Macdonald Jan 2000

Sub-Surface Migration Of An Oil Pollutant Into Aquifers, Louise Ann Macdonald

School of Geography, Earth and Environmental Sciences Theses

The risk to groundwater quality following a sub-surface spillage of immiscible pollutants such as oil, petroleum and other organic chemicals is an increasingly potent threat, through escalating industrial application of such pollutants. This study significantly enhances the understanding of the flow of immiscible pollutants within soil, through field scale investigations to define the spatial variability and extent of a contaminated area and the development of a comprehensive framework for the analysis of oil pollutant migration. This study represents a first attempt by researchers to analyse oil pollutant migration on a wide range of scales, from pore- to field-level. The research …

Complexation And Particle-Water Interactions Of Nickel In Estuaries, Manuela Martino Jan 2000

Complexation And Particle-Water Interactions Of Nickel In Estuaries, Manuela Martino

School of Geography, Earth and Environmental Sciences Theses

The speciation and particle-water interactions of Ni were investigated in three estuaries with contrasting pollution levels, hydrodynamics and geochemical characteristics. Samples of water and sediments were collected seasonally from the Tamar, Tweed and Mersey Estuaries. The chemical speciation of dissolved Ni was determined by adsorptive cathodic stripping voltammetry (ACSV), and the sorptive behaviour of Ni was studied under simulated estuarine conditions using " Ni coupled to liquid scintillation counting. A relatively high particle reactivity was observed only in the Tamar Estuary, where ACSV-non labile Ni was removed in the low salinity region, followed by addition of ACSV-labile Ni in the …

Fundamental Studies Of Interferences In Icp - Ms, Linda Kathleen Rowley Jan 2000

Fundamental Studies Of Interferences In Icp - Ms, Linda Kathleen Rowley

School of Geography, Earth and Environmental Sciences Theses

Methods of temperature measurement by mass spectrometry have been critically reviewed. It was concluded that the most appropriate method depended critically on the availability of fundamental data, hence a database of fundamental spectroscopic constants, for diatomic ions which cause interferences in ICP-MS, was compiled. The equilibration temperature, calculated using the different methods and using various diatomic ions as the thermometric probes, was between c.a. 400 - 10,000 K in the central channel, and between c.a. 600 - 16,000 K when the plasma was moved 1.8 mm off-centre. The wide range in temperature reflected the range of temperature measurement methods and …

The Determination Of Trace Metals By Capillary Electrophoresis, Simon Andrew Hardy Jan 2000

The Determination Of Trace Metals By Capillary Electrophoresis, Simon Andrew Hardy

School of Geography, Earth and Environmental Sciences Theses

The development of a capillary electrophoresis (CE) method for the determination of inorganic and organo mercury species as their dithizone sulphonate (DzS) complexes using coated capillary columns is described. The complexes were pre-formed before injection and detection was by direct measurement of the visible absorbance of the complexes. Dithizone sulphonate was used in place of cysteine to separate methyl mercury in the final stage of a simplified Westoo extraction procedure. The method was than applied to the analysis of methyl mercury in a crab and several fish meat samples. Good quantitative performance is demonstrated by spiking experiments and analysis of …

Graduate School of Oceanography Faculty Publications

A large number of oxygenated organic chemicals (peroxyacyl nitrates, alkyl nitrates, acetone, formaldehyde, methanol, methylhydroperoxide, acetic acid and formic acid) were measured during the 1997 Subsonic Assessment (SASS) Ozone and Nitrogen Oxide Experiment (SONEX) airborne field campaign over the Atlantic. In this paper, we present a first picture of the distribution of these oxygenated organic chemicals (Ox‐organic) in the troposphere and the lower stratosphere, and assess their source and sink relationships. In both the troposphere and the lower stratosphere, the total atmospheric abundance of these oxygenated species (ΣOx‐organic) nearly equals that of total nonmethane hydrocarbons (ΣNMHC), which have been traditionally …

Evidence Issues In Domestic Violence Civil Cases, Jane C. Murphy, Jane H. Aiken Jan 2000

Evidence Issues In Domestic Violence Civil Cases, Jane C. Murphy, Jane H. Aiken

All Faculty Scholarship

New laws and policies aimed at protecting victims of domestic violence have been adopted across the country over the last twenty years.The legal approaches taken to protect battered women and control family violence have resulted in significant changes in family law. New laws include statutes permitting civil protection or restraining orders, and laws requiring that domestic violence be considered in custody and/or visitation decisions. Both of these types of statutory reforms can provide protection to adult victims of domestic violence and their children. Evaluating a parent's fitness by considering past acts of violence to other family members results in decisions …

Collecting Child Support: A History Of Federal And State Initiatives, Jane C. Murphy, Naomi R. Cahn Jan 2000

Collecting Child Support: A History Of Federal And State Initiatives, Jane C. Murphy, Naomi R. Cahn

All Faculty Scholarship

In this article we sketch an overview of the increasing federal involvement in the child-support area. Because the federal role has grown so dramatically over the past 25 years, family law practitioners need to understand the different federal programs and requirements that affect state management of child-support programs. While for many low-income parents state agencies handle child-support establishment and collection, the federalization of child support has practical implications when it comes to both establishing and enforcing child support. For example, as the time limits of the Personal Responsibility and Work Opportunity Reconciliation Act begin to have their effects, child support …

Race, Space And Place: The Internal Critique Of The Empowerment Zones Program, Audrey Mcfarlane Jan 2000

Race, Space And Place: The Internal Critique Of The Empowerment Zones Program, Audrey Mcfarlane

All Faculty Scholarship

This Article examines the extent to which the Empowerment Zones Program is properly viewed as a neutral, rational, and beneficial program for poor, inner-city communities and their residents by exploring the limits and potential of its chief mechanism, economic development, as a tool to achieve social justice for the inner cities. This Article grounds its exploration within the contested terrain of the city, not simply as a legal or juridical concept, but in terms of its reality as a lived place on the eve of the 21st century.

Analysis Of Infragravity Frequency Sediment Transport On Macrotidal Beaches, Andrew Nicholas Saulter Jan 2000

Analysis Of Infragravity Frequency Sediment Transport On Macrotidal Beaches, Andrew Nicholas Saulter

Other Faculty of Science and Engineering Theses

Many cross-shore sediment transport models use simple treatments of infragravity frequency (0.005- 0.05Hz) processes. For example, infragravity waves have been assumed to provide solely a 'drift velocity' for transport of sediment mobilised by incident frequency waves (0.05-0.5Hz) and be 100% reflected at the shoreline. Furthermore, numerous models calculate broken incident wave heights on the basis of water depth only. This work investigates both the processes underlying infragravity frequency variations in the crossshore velocity field, and the resulting effect of such variations on sediment suspension and transport. Data were selected from three beach experiments in order to compare observations from a …

Emission, Dispersion And Local Deposition Of Ammonia Volatilised From Farm Buildings And Following The Application Of Cattle Slurry To Grassland, Richard Alexander Hill Jan 2000

Emission, Dispersion And Local Deposition Of Ammonia Volatilised From Farm Buildings And Following The Application Of Cattle Slurry To Grassland, Richard Alexander Hill

Other Faculty of Science and Engineering Theses

Emissions of ammonia (NH3) into the atmosphere, principally from agricultural sources, have been implicated in the pollution of forests, moorlands and grasslands, through the subsequent deposition of reduced nitrogen (NHx -N). Consequently, legislation has been implemented to control both the transboundary transport and local environmental impacts of NHx. This thesis investigates the emission, dispersion and local deposition of NH3 from two sources that are major components of national NH3 emissions inventories, slurry applied to grassland and naturally ventilated cattle buildings. A N balance method was identified for determining the time-average deposition of NH3 downwind of a farm building, whilst an …
