The Effect Of Low Energy Electron And Uv/Vis Radiation Aging On The Electron Emission Properties And Breakdown Of Thin-Film Dielectrics, John R. Dennison, C. D. Thomson, Alec Sim

All Physics Faculty Publications

Studies of secondary and backscattered electron yield curves of thin-film dielectrics have recently been made using pulsed, low current electron beam methods to minimize insulator charging. These capabilities have allowed us to investigate the evolution of surface and internal charge profiles as a function of low energy electron (keV) pulsed-electron fluence to determine how quickly insulators charge, and how this can affect subsequent electron emission properties. We have also studied critical incident electron energies that result in electrical breakdown of insulator materials and the effect of breakdown on subsequent emission, charging and conduction. The qualitative physics of such processes in …

An Environmentally Enlightened Accounting, Jesse Dillard, Darrell Brown, Scott Marshall

Business Faculty Publications and Presentations

Environmental stewardship must become a primary concern if management is to adequately fulfill its societal responsibilities. Management and accounting information systems must aggressively respond to these emerging requirements in order to support adequately the associated information needs as well as to design organizational systems that motivate and facilitate desired behavior. Our purpose here is to consider a framework useful for developing environmentally enlightening management and accounting information systems that take into account alternative environmental perspectives. The framework can be used to develop prototypes representing different levels of environmental enlightenment and, as such, can provide general guidance for moving collectives and …

Development Of A Solid Electrolyte For Hydrogen Production, Kiran Sampat Gaikwad

USF Tampa Graduate Theses and Dissertations

Electrolytic cells convert chemical energy directly into electrical energy cleanly and efficiently. An integral component of a fuel cell and an electrolytic cell is the electrolyte, a material that conducts ions. Liquid electrolytes can be aqueous as in the phosphoric acid and alkaline fuel cells, or molten, as in the molten carbonate fuel cells. A solid electrolyte is preferable because it allows sturdier, more efficient and corrosion resistant systems to be built.

The main objective of this work is to develop a solid electrolyte for hydrogen production by electrolysis of hydrogen sulfide. Barium Hydrogen Phosphate, Barium Dihydrogen Phosphate, Cesium Hydrogen …

Introduction: The Swiss Protestant Reformation

Swiss American Historical Society Review

On November 28th , 2002 the innocent family Lieu awoke to begin another day of prayer, devotion and work in their hometown of Danane in the Ivory Coast, West Africa. However, at 9 AM gunfire erupted and rebel forces began dropping bombs on the town, announcing that the current civil war in the Ivory Coast had reached Danane, terrifying the citizens and traumatizing the Lieu family to such an extent that they and many of their neighbors resolved to flee, with literally just the shirts on their backs, into the jungle. For months they lived like animals in the wilderness …

Effects Of Competition On Copulatory Behaviors In Pseudoxychila Tarsalis (Coleoptera: Cicindelidae), November 2004, Hilary Wilson

Monteverde Institute: Tropical Ecology and Conservation

This study examines the effects of competition on copulatory behaviors of the tiger beetle Pseudoxychila tarsalis. I tested the hypothesis that copulatory behavior of a P. tarsalis mating pair in the presence of an additional male would induce significant behavioral changes, including longer amplexus time and increased frequency of a variety of copulatory behaviors. Trials were conducted with either one male and one female, or two males and one female, and the behaviors of one copulatory amplexus recorded per trial. No statistical differences were found for the male behaviors of time until mount, amplexus duration, or number of intromissions, but …

Discharge And Drift Of Benthic Macroinvertebrates In A Tropical Montane Stream, November 2004, Megan Moore

Monteverde Institute: Tropical Ecology and Conservation

Several studies in temperate regions have observed an active behavioral response of stream invertebrates to environmental factors. However, few of these studies have been conducted in the tropics and the behavior of tropical stream invertebrates is unknown. In an attempt to improve the knowledge on tropical stream ecology, this study observed indirect behavioral responses to discharge within the drift as well as the benthic macroinvertebrate community. Drift, benthic, and discharge samples were taken at 11 sites along the Quebrada Máquina from October 28-November 13 of 2004. The drift community richness and diversity and discharge resulted in a non-significant, negative trend. …

The Effects Of Edge And Pollution On Lichen Richness, Abundance, And Distribution In Cañitas, Costa Rica, November 2004, Jenny Bedell-Stiles

Monteverde Institute: Tropical Ecology and Conservation

Lichens are commonly known to be biological indicators of pollution and edge effects. Their use as indicators in temperate regions is well documented, however, less is known about their function as a bioindicator in the tropics. There is also debate over the consequences of edge effects, such as increased temperature, and less moisture and wind, on lichen richness and abundance. In this study lichen communities on tree trunks in three habitat sites (primary forest, pasture, and roadside) were examined. In total 88 trees were censused in order to determine lichen richness, abundance, and similarity. Overall 68 species of lichen were …

Host Tree Dispersal Method And Community Composition Of Vascular Epiphytes, November 2004, Kathleen White

Monteverde Institute: Tropical Ecology and Conservation

The pattern of epiphyte distribution along host trees is a function of many variables. This study examined how the dispersal syndrome of the host tree affected the composition of epiphyte dispersal syndromes in that tree. It was expected that a host tree species bearing bird-dispersed fruits would harbor more epiphytes exhibiting the bird-dispersal syndrome than a tree that has fruits eaten by terrestrial mammals. Two species of host trees were surveyed, Inga sierrae, a tree with terrestrial-mammal dispersed fruits, and Sapium glandulosum, a tree with fruits that are bird-dispersed. Nine of each tree species were sampled. The tree with terrestrial …

Effects Of Fragmentation And Human Disturbance On Mammal Communities In San Luis And Monteverde, Costa Rica, November 2004, Lindsay Crawford

Monteverde Institute: Tropical Ecology and Conservation

Mammals occupy important roles in tropical ecosystems and can often be keystone species, controlling the composition of their communities. This study compared mammal communities in Monteverde and San Luis, Costa Rica, two regions that differ in their current and historical patterns of fragmentation. Three habitats per region, representing a disturbance gradient, were surveyed using scent stations. Prints as well as visual observations were recorded. No significant differences were found in species richness across zones or across habitats. However, overall diversity was consistently higher in Monteverde and locally highest in edge habitats in both regions. Local richness patterns (across habitats) follow …

Macroinvertebrate Communities And Streambed Substrates Of A Dammed Stream In Monteverde, Costa Rica, November 2004, John Robert Rancourt

Monteverde Institute: Tropical Ecology and Conservation

The purpose of this study was to determine how the dam placed in the Quebrada Máquina, Monteverde, Costa Rica, affects the abundance, richness, and diversity of benthic macroinvertebrate communities. Samples were collected from 20 sites, 50m upstream and downstream of the dam. The relative percentage of streambed substrate composition was also documented at all test sites. There were significant decreases in Order richness and diversity as absolute distance from the dam decreased. In addition, the substrate composition was found to be homogeneous for sand directly upstream of the dam. This leads to the conclusion that the dam has created a …

Vertical Stratification Of Hummingbird Pollinated Plants In Relation To Corolla Length, November 2004, Eleanor Gordon

Monteverde Institute: Tropical Ecology and Conservation

For members of feeding guilds to co-exist in the same community, species must partition niches to avoid competition. In Tropical Lower Montane Wet Forest, hummingbirds are an important and numerous pollinators, suggesting a large number of niche partitioning mechanisms. Hummingbirds are often tightly co-evolved with the plants they pollinate, having bill lengths corresponding to the length of the flower they pollinate. It is proposed in this study that there is a relationship between heights of hummingbird pollinated plant and length of flower corolla. It is hypothesized that short corolla flowers will exist in some strata and long corolla flowers in …

A Protozoan Parasite In Wild And Captive Monarch Butterfly Populations Near Monteverde, Costa Rica, November 2004, Joanna Hsu

Monteverde Institute: Tropical Ecology and Conservation

Although the protozoan parasite Ophyrocystis elektroscirrha was first recovered from Danaus plexippus (Nymphalidae: Danainae) and Danaus gilippus populations in Florida in 1966 and has since been found in many other monarch and queen populations worldwide, no previous studies have shown that this parasite infects butterflies in Costa Rica. This study is the first to do so, documenting the occurrence of Ophryocystis elektroscirrha in a wild and butterfly garden population of D. plexippus near Monteverde, Costa Rica. Although only a few infected individuals were found in both populations, there was a stark contrast in the number of parasites per individual between …

Stream Site Selection Of Hyalinobatrachium Fleischmanni (Centrolenidae), November 2004, Alicia Ward

Monteverde Institute: Tropical Ecology and Conservation

Census work and habitat analysis for the glass frog species Hyalinobatrachium fleischmanni was performed on four streams in Cañitas and Monteverde, Costa Rica. At each of six sites, the habitat occupied by H. fleischmanni was contrasted with a nearby, paired site where individuals were absent. Seven habitat parameters were investigated: water quality based on dissolved oxygen and phosphate content; water speed; discharge; distance from human development; extent of canopy cover; and presence or absence of common monocots (Zingiberaceae: Hedychium coronarium, Costaceae: Costus spp., Musaceae: Musa acuminata). No statistically significant differences were found between Occupied and Unoccupied locations though patterns suggested …

Development Of Auditory Event-Related Potentials In Young Children And Relations To Word-Level Reading Abilities At Age 8 Years, Kimberly Espy, Dennis L. Molfese, Victoria J. Molfese, Arlene Modglin

Developmental Cognitive Neuroscience Laboratory: Faculty Publications

A relationship between brain responses at birth and later emerging language and reading skills have been shown, but questions remain whether changes in brain responses after birth continue to predict the mastery of language-related skills such as reading development. To determine whether developmental changes in the brain-based perceptual skills are systematically related to differences in word-level reading proficiency at age 8 years, brain event-related potentials (ERPs) to speech and nonspeech stimuli were recorded annually at the ages of 1 through 8 years in a sample of 109 typically developing children. Two measures of word-level reading (one that requires decoding of …

Post-Graduation Economic Status Of Master's Degree Recipients: A Study Of Earnings And Student Debt, Gary L. Donhardt

Journal of Student Financial Aid

This study examined the employment activity of master's graduates and the student debt they carry into the workplace over the early years following graduation. State unemployment insurance records were merged with student data files to determine the relationship between academic achievement, financial success, and debt burden of these graduates. Quarterly earnings from the first two years following graduation were regressed on age, grade point average, academic major, gender, race, and industry. Major, industry, age, and grade point average were significant in both years examined. Student debt was regressed over grade point average, gender, race, age, and academic major. Major, grade …

Fiscal Stress: Worldwide Trends In Higher Education Finance, Hans Vossensteyn

Journal of Student Financial Aid

While higher education is generally a high priority in boosting economic development, public budgets to sustain expansion of higher education systems remain limited around the globe. This fiscal stress creates an impetus for governments to develop various strategies to meet the growing demand-from both students and society-for higher education services. This article explores worldwide trends to cope with this issue. It addresses policy developments aimed at increased efficiency in higher education, such as development towards institutional autonomy and performance-based funding. In addition, the article shows that the issue of cost-sharing is gaining worldwide importance. Students and their families are required …

Effectiveness Of Early Pregnancy Ultrasound In Diagnosing Fetal Abnormalities In High Risk Women, S Munim, N Khowaja

Department of Obstetrics & Gynaecology

Objective: To assess the efficacy of 11-14 weeks ultrasound in the diagnosis of fetal abnormalities in high risk women.
Methods: Prospective study conducted at a teaching hospital in Karachi, Pakistan. One hundred ultrasound (mini-anomaly) scans were performed on 97 high-risk women, between 11-14 weeks of gestation.
Results: The most common indication for the ultrasound scan in the study, was previous history of structural or chromosomal abnormalities (40%) followed by advanced maternal age (22%). Out of 100 ultrasounds performed, two were found to have structural abnormalities at the time of mini-anomaly scan performed at 11-14 weeks. None of the ultrasound scans …
