Comparability Of Functional Mri Response In Young And Old During Inhibition, Kristy A. Nielson, Scott Aaron Langenecker, Thomas J. Ross, Hugh Garavan, Stephen M. Rao, Elliot Stein

Psychology Faculty Research and Publications

When using fMRI to study age-related cognitive changes, it is important to establish the integrity of the hemodynamic response because, potentially, it can be affected by age and disease. However, there have been few attempts to document such integrity and no attempts using higher cognitive rather than perceptual or motor tasks. We used fMRI with 28 healthy young and older adults on an inhibitory control task. Although older and young adults differed in task performance and activation patterns, they had comparable hemodynamic responses. We conclude that activation during cognitive inhibition, which was predominantly increased in elders, was not due to …

Fmri Of Healthy Older Adults During Stroop Interference, Scott Aaron Langenecker, Kristy A. Nielson, Stephen M. Rao

Psychology Faculty Research and Publications

The Stroop interference effect, caused by difficulty inhibiting overlearned word reading, is often more pronounced in older adults. This has been proposed to be due to declines in inhibitory control and frontal lobe functions with aging. Initial neuroimaging studies of inhibitory control show that older adults have enhanced activation in multiple frontal areas, particularly in inferior frontal gyrus, indicative of recruitment to aid with performance of the task. The current study compared 13 younger and 13 older adults, all healthy and well educated, who completed a Stroop test during functional magnetic resonance imaging. Younger adults were more accurate across conditions, …

Foreign Investment Restrictions As Industrial Policy: The Case Of Canadian Telecommunications, Robert Crandall, Hal Singer

Canadian Journal of Law and Technology

We assess the economic harms that would accrue if Canada were to adopt asymmetric rules of foreign ownership for incumbent carriers and entrants. We explain the current Canadian regulatory climate surrounding foreign investment in Canadian telecommunications. Competition in the telecommunications industry is generally robust, which suggests that rules aimed at favouring entrants are not necessary. Moreover, Canadian entrants are equally capable of attracting foreign capital as Canadian incumbents, which suggests that foreign investment rules aimed at favouring entrants are especially unwise.

Next, we review the U.S. attempt to stimulate competition in local telecommunications markets through an analogous form of asymmetrical …

Effect Of Stochastic Dead Space On Noise In Avalanche Photodiodes, Oh-Hyun Kwon, Majeed M. Hayat, Joe C. Campbell, Bahaa E.A. Saleh, Malvin Carl Teich

Electrical and Computer Engineering Faculty Research and Publications

A stochastic dead-space model for impact ionization is developed and used to study the effect of the soft nature of the ionization capability of carriers on the excess noise factor of avalanche photodiodes. The proposed model is based on the rationale that the gradual, or soft, transition in the probability density function (PDF) for the distance from birth to impact ionization can be viewed as that resulting from uncertainty in the dead space itself. The resulting soft PDF, which is parameterized by a tunable softness parameter, is used to establish the limitations of the existing hard-threshold ionization models in ultrathin …

Optimized Breakdown Probabilities In Al/Sub 0.6/Ga/Sub 0.4/As-Gaas Heterojunction Avalanche Photodiodes, Oh-Hyun Kwon, Majeed M. Hayat, Joe C. Campbell, Bahaa E.A. Saleh, Malvin Carl Teich

Electrical and Computer Engineering Faculty Research and Publications

Recently, it has been shown that the noise characteristics of heterojunction Al/sub 0.6/Ga/sub 0.4/As-GaAs avalanche photodiodes (APDs) can be optimized by proper selection of the width of the Al/sub 0.6/Ga/sub 0.4/As layer. Similar trends have also been shown theoretically for the bandwidth characteristics. The resulting noise reduction and potential bandwidth enhancement have been attributed to the fact that the high bandgap Al/sub 0.6/Ga/sub 0.4/As layer serves to energize the injected electrons, thereby minimizing their first dead space in the GaAs layer. We show theoretically that the same optimized structures yield optimal breakdown-probability characteristics when the APD is operated in Geiger …

Decision Support In Information Systems Security, Omar F. El-Gayar, Brian D. Fritz

Research & Publications

As the structure of modern organizations shifts, so correspondingly must the methodologies which underlie the evaluation and development of the security posture of their information systems. We have witnessed an ever-growing gap between organizational policy and technology. We have also witnessed an ever increasing complexity of decisions regarding the planning and design of IS security. Within this paper, we propose a decision support framework consistent with security and decision theory and develop a model of the decision analysis space suitable for multiple criteria decision making (MCDM). The adoption of MCDM techniques within the context of this model can show inherent …

Application Of Fuzzy Logic To Multiple Criteria Decision Making In Aquacultural Planning, Omar F. El-Gayar

Research & Publications

The field of regional planning is characterized by the large number of issues and attributes involved, and regional planning for aquaculture development is no exception. Moreover, aquacultural plans do not have clearly defined objectives and require information that, if exist, is often imprecise and uncertain.This paper applies fuzzy set theory to multiple criteria decision making (MCDM) in aquaculture planning. In effect, the paper demonstrates how fuzzy set theory can be used to explicitly account for the inherent uncertainty encountered when planning for aquaculture development in a given region. A case study for regional aquaculture planning in Northern Egypt demonstrates the …

Effect Of Intensity Increment On P300 Amplitude, Tim Skinner

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to determine the effects of task difficulty on the amplitude and latency of the P300 by altering the intensity of the oddball stimulus. A P300 was obtained on 22 adult subjects ranging in age from 21 to 34 years of age (mean = 24 years) with normal hearing. The "frequent stimulus" was a 1000 Hz or 4000 Hz tone burst, gated with a rise and fall time of 10 msec and 20 msec plateau, presented at 75 dBn HL The "oddball stimulus" was a tone burst of the same frequency (1000 Hz or 4000 …
