Molecular Orbital Studies Of Nitrosyl Metalloporphyrin Complexes, John P. Graham, Genevive Brown

Journal of the Arkansas Academy of Science

Molecular orbital calculations are applied to the study of the structure and bonding of nitrosyl metalloporphyrin complexes. The Fenske-Hall approximate molecular orbital method and the Amsterdam Density Functional (ADF) method are used. The calculations provide qualitative and quantitative explanations for the observed structural differences between the nitrosyl porphyrin complexes ofiron, manganese, and cobalt. It is proposed that the energy of the highest occupied molecular orbital (HOMO) of these complexes is primarily responsible for the observed structural differences. The interaction between the nitrosyl ligand and metal dz2 orbital results in an antibonding orbital that is occupied in the complexes of Fe …

Distribution And Status Of Ophiogomphus Westfalli (Ondonata: Gomphidae) In Missouri And Arkansas, George L. Harp, Linden Trial

Journal of the Arkansas Academy of Science

Ophiogomphus westfalli is endemic to the Interior Highlands (Ozark Plateaus and Ouachita Mountains), in Missouri, Arkansas and southeastern Kansas. First described in 1985, its life history is still little known. Prior to 1997, this species was known from only six sites in Missouri and 10 in Arkansas. From late May through late July in both 1999 and 2000 we surveyed 49 sites, three of them twice each, on Missouri Ozark streams inorder to further clarify the distribution and relative abundance of this dragonfly. Adults, nymphs and/or exuviae were found at 23 sites. Literature and museum searches bring to 72 locations …

Middle-Ear Function With Tympanic-Membrane Perforations. I. Measurements And Mechanisms, Susan E. Voss, John J. Rosowski, Saumil N. Merchant, William T. Peake

Engineering: Faculty Publications

Sound transmission through ears with tympanic-membrane ~TM! perforations is not well understood. Here, measurements on human-cadaver ears are reported that describe sound transmission through the middle ear with experimentally produced perforations, which range from 0.5 to 5.0 mm in diameter. Three response variables were measured with acoustic stimulation at the TM: stapes velocity, middle-ear cavity sound pressure, and acoustic impedance at the TM. The stapes-velocity measurements show that perforations cause frequency-dependent losses; at low frequencies losses are largest and increase as perforation size increases. Measurements of middle-ear cavity pressure coupled with the stapes-velocity measurements indicate that the dominant mechanism for …

Model Based Effective Cell Volume Calculation In Ultrasound Tissue Characterization, Di Lai

Theses

In reflective ultrasonic imaging, some statistical parameters can be extracted from the backscattered RF signal. Applying Rayleigh statistics or non-Rayleigh statistics to these parameters, the underlying tissue parameters such as effective scatterer number density that characterize the tissues can be further estimated. However, if the statistical processing is applied to the time domain signal, narrow band excitation pulse needs to be used when we consider the frequency dependency of the backscattered signal. The scattering resolution volume is also difficult to estimate. Chen, et al proposed a different method to determine the frequency-dependent effective scatterer number density, which is the actual …

Does Community Notification For Sex Offenders Violate The Eighth Amendment's Prohibition Against Cruel And Unusual Punishment - A Focus On Vigilantism Resulting From Megan's Law., Alex B. Eyssen

St. Mary's Law Journal

Community notification of a sex offender’s presence may be violating the Eighth Amendment’s protection from Cruel and Unusual Punishment. Under Megan’s Law and other sex offender registration statutes, individuals that have completed a prison sentence for a sex crime may have to register as a sex offender. The information of the individual including his name, address, physical description, date of birth, social security number, employer, offense, and picture, is publicly disseminated. As an unintended consequence, individuals who have served their time may have to suffer additional punishment in the form of harassment, vigilantism, and violence.

Securities Price Risks And Financial Derivative Markets, Peter H. Huang

Publications

The financial and popular media report almost daily on the volatility of securities market prices. Yet, many people continue to buy securities to hedge against or speculate on certain risks. People can also buy or sell derivatives to hedge against or speculate on fluctuations in securities prices. This Article discusses three regulatory policy implications of utilizing derivatives markets to reallocate the bearing of securities price risks. First, if there are too few non-redundant derivative markets, a competitive market equilibrium allocation of securities price risks is typically constrained Pareto inefficient. This financial economic result means that for typical economies, a regulator …

What Moves Stock Markets? Evidence That Uk Stock Prices Deviate From Fundamentals, David E. Allen, Wenling Yang

Research outputs pre 2011

This article examines the deviation of the UK market index from market fundamentals implied by the simple dividend discount model and identifies other components that also affect price movements. The components are classified as permanent, temporary, excess stock returns and nonfundamental innovations in terms of a multivariate moving average model (Lee (1998)). We find that time varying discounted rates play an active role in explaining price deviations.

Skewness Is The Name Of The Game, Y. H. Cheung

Research outputs pre 2011

Theoretical models of risk taking attempt to explain why risk-averse individuals participate in unfair gambles. This paper evaluates the two explanations as to why rational individuals would accept gambles with negative expected returns. It is found that it is skewness, not the mean or the variance of the prize distribution that attracts risk-averse gamblers. However, evidence shows that there seems to be an optimal trade-off between operators’ sales revenues and skewness of the pay-off; a point that designer of gambling games needs to heed to.

Heckman's Methodology For Correcting Selectivity Bias : An Application To Road Crash Costs, Margaret Giles

Research outputs pre 2011

Aggregate road crash costs are traditionally determined using average costs applied to incidence figures found in Police-notified crash data. Such data only comprise a non-random sample of the true population of road crashes, the bias being due to the existence of crashes that are not notified to the Police. The traditional approach is to label the Police-notified sample as 'non-random' thereby casting a cloud over data analyses using this sample. Heckman however viewed similar problems as 'omitted variables' problems in that the exclusion of some observations in a systematic manner (so-called selectivity bias) has inadvertently introduced the need for an …

On The Evolution Of Probability-Weighting Function And Its Impact On Gambling, Steven Li, Yun Hsing Cheung

Research outputs pre 2011

It is well known that individuals treat losses and gains differently and there exists non-linearity in probability. The asymmetry between gains and losses is highlighted by the reflection effect. The non-linearity in probability is described by the curvature of the probability-weighting function. This paper studies the evolution of the probability-weighting function. It is assumed that the probability weighting for an individual follows a mean-reverting stochastic process. The Monte Carlo simulation technique is employed to study the evolution of the weighting function. The evolution of the probability- weighting function implies that an individual does not treat gains or losses consistently over …

M-Garch Hedge Ratios And Hedging Effectiveness In Australian Futures Markets [Working Paper], Wenling Yang

Research outputs pre 2011

This study estimates optimal hedge ratios using various econometric models. Applying daily AOIs and SPI futures on the Australian market, optimal hedge ratios are calculated from the OLS regression model, the bivariate vector autoregressive model (BVAR), the error-correction model (ECM) and the multivariate diagonal Vec GARCH Model. The hedging effectiveness is measured in terms of ex-post and ex-ante risk-return tradeoff at various forecasting horizons. It is generally found that the GARCH time varying hedge ratios provide the greatest portfolio risk reduction, particularly for longer hedging horizons, but they do not generate the highest portfolio return.

Wetland Vegetation Monitoring, 2000/2001 (Salinity Action Plan), B. Franke, R. Gurner, R. Froend

Research outputs pre 2011

This report represents the vegetation component of a project designed to provide ongoing monitoring of wetland salinity and biological resources in wetlands of the agricultural zone of south-west Western Australia. Maintenance of wetland biological diversity in the agricultural zone is one of the major objectives of the Salinity Action Plan. Due to their low position in the landscape, wetlands are the habitat most affected by salinisation.

B-Nodes: A New Scalable High Level Abstraction Model, Stanislaw P. Maj, Craig William Caulfield

Research outputs pre 2011

This paper proposes a new modeling technique called B-Nodes. B-Nodes represent a new, high-level abstraction that allows technical detail to be controlled using top-down recursive decomposition. This abstraction. is independent of architectural detail and can therefore accommodate rapid changes in technology. The use of recursive decomposition allows B-Nodes to be used not only for entire e-commerce system but also sub-modules within this system. The use of fundamental units allows the performance of heterogeneous technologies to be compared and other units to be derived. Results to date indicate no comparable model exists. Should further work validate this technique the authors recommend …

Developing E-Learning Environments That Support Knowledge Construction In Higher Education, Ron Oliver

Research outputs pre 2011

Much of the conventional development of Web-based learning environments the creation of electronic forms of existing print-based materials. In such instances the Web-based courses have tended to display limited evidence of an underpinning learning design and varying degrees of use of the opportunities and affordances of the new technologies. This paper provides an overview of instructional design principles that can guide the creation of Web-based learning materials that support learner engagement and knowledge construction. The paper describes the attributes of constructivist learning settings and provides some examples of explicit learning designs that can be applied in the design of Web-based …

Educating Professional Software Engineers: Pathways And Progress In The Australian Experience, Rick Duley, David Veal, Stanislaw P. Maj

Research outputs pre 2011

Australia has seized the international initiative in the recognition of software engineers as professionals. Of the 37 universities in Australia offering undergraduate courses in computing, eleven offer courses in software engineering which are accredited by the Institute of Engineers, Australia (IEAust) and which may lead the graduate to membership of the Institute. In this way, the Institute has plausible claim to being the first national professional engineering body in the world to have accredited four-year undergraduate software engineering degrees as professional qualifications. The paper traces the development of the relationship between the Institute of Engineers and the computing industry and …

Inference Of Regular Languages Using Model Simplicity, Philip Hingston

Research outputs pre 2011

We describe an approach that is related to a number of existing algorithms for the inference of a regular language from a set of positive (and optionally also negative) examples. Variations on this approach provide a family of algorithms that attempt to minimise the complexity of a description of the example data in terms of a finite state automaton model. Experiments using a standard set of small problems show that this approach produces satisfactory results when positive examples only are given, and can be helpful when only a limited number of negative examples is available. The results also suggest that …

Learning Objects: Supporting Flexible Delivery Of Flexible Learning, Ron Oliver

Research outputs pre 2011

There are now many educational organizations and institutions that have decided on flexible delivery and online learning as strategies that they are keen to pursue. While many educators value online delivery of programs for the flexibility and opportunities offered, the environment offers far more than these outcomes alone. Online delivery supports and encourages very powerful learning environments and has the prospect to transform education if approached in the correct fashion. Across the world, conventional approaches to the design and development of online learning environments in higher education frequently result in many lost opportunities for both teachers and learners. These losses …

Classification Of Bandlimited Fsk4 And Fsk8 Signals, Visalakshi Ramakonar, Daryoush Habibi, Abdesselam Bouzerdoum

Research outputs pre 2011

This paper compares two types of classifiers applied to bandlimited FSK4 and FSK8 signals. The first classifier employs the decision-theoretic approach and the second classifier is a neural network structure. Key features are extracted using a zero crossing sampler. A novel decision tree is proposed and optimum threshold values are found for the decision theoretic approach. For the neural network, the optimum structure is found to be the smallest structure to give 100% overall success rate. The performance of the both classifiers has been evaluated by simulating bandlimited FSK4 and FSK8 signals corrupted by Gaussian noise. It is shown that …
