Redefining Art As An Experience, Pedro Zasciurinskis Lopes Jan 2008

Redefining Art As An Experience, Pedro Zasciurinskis Lopes

HIM 1990-2015

Art is present in nearly every aspect of our lives. The concept of art, however, is not easy to define. When discussing the subject of art, one must consider experience, art, and the aesthetic. These three concepts complement each other, but are difficult to distinguish. As a result, meaningful and coherent discussions about art are difficult to achieve. I believe that in order to discuss what good art, meaningful art, fine art, and useful art are, one must first have a clear understanding of what art is. In this thesis I attempt to build a foundation for meaningful discussion about …

Change Of Physical Context Impairs Cardiovascular Habituation To Stress, Kevin M. Palmer Jan 2008

Change Of Physical Context Impairs Cardiovascular Habituation To Stress, Kevin M. Palmer

HIM 1990-2015

The present study examined whether cardiovascular habituation to stress is affected by a change in the physical context in which a stressor is encountered. Twenty-five undergraduate students at the University of Central Florida, Palm Bay Campus, were exposed to 4 trials of a stressor consisting of mental arithmetic while under evaluative observation. It was hypothesized that if participants experienced a change in the physical context in which stress was experienced on the final trial, they would demonstrate impaired habituation to stress as indicated by measures of heart rate and blood pressure. Physical context was manipulated by either asking participants to …

Kolattukudy, Carlos Martín, Stewart T. Cole, Brigitte Gicquel, Deshmukh N. Gopaul, Mary Jackson

Faculty Bibliography 2000s

Similarities between Mycobacterium tuberculosis phoP-phoR mutants and the attenuated laboratory strain M. tuberculosis H37Ra in terms of morphological and cytochemical properties, lipid content, gene expression and virulence attenuation prompted us to analyze the functionality of this two-component regulator in the latter strain. Sequence analysis revealed a base substitution resulting in a one-amino-acid change in the likely DNA-binding region of PhoP in H37Ra relative to H37Rv. Using gel-shift assays, we show that this mutation abrogates the ability of the H37Ra PhoP protein to bind to a 40-bp segment of its own promoter. Consistent with this result, the phoP gene from H37Rv …

Ecology And Life History Of An Amazon Floodplain Cichlid: The Discus Fish Symphysodon (Perciformes: Cichlidae), William G. R. Crampton Jan 2008

Ecology And Life History Of An Amazon Floodplain Cichlid: The Discus Fish Symphysodon (Perciformes: Cichlidae), William G. R. Crampton

Faculty Bibliography 2000s

The discus fishes of the genus Symphysodon are popular ornamental cichlids that occur in floodplain lakes and flooded forests of the lowland Amazon Basin. These habitats are characterized by extreme seasonal fluctuations in the availability of food, shelter and dissolved oxygen, and also the densities of predators and parasites. Most aspects of discus biology are influenced by these fluctuating conditions. This paper reports an autoecological study of the western Amazonian discus S. haraldi (until recently classified as S. aequifasciatus). This species feeds predominantly on algal periphyton, fine organic detritus, plant matter, and small aquatic invertebrates. At high water it forages …

Use Of Baculovirus-Expressed Glycoprotein H In An Enzyme-Linked Immunosorbent Assay Developed To Assess Exposure To Chelonid Fibropapillomatosis-Associated Herpesvirus And Its Relationship To The Prevalence Of Fibropapillomatosis In Sea Turtles, Lawrence H. Herbst, Shefali Lemaire, Ada R. Ene, David J. Heslin, Llewellyn M. Ehrhart, Dean A. Bagley, Paul A. Klein, Jack Lenz

Faculty Bibliography 2000s

Chelonid fibropapillomatosis-associated herpesvirus (CFPHV) is an alphaherpesvirus believed to cause marine turtle fibropapillomatosis (FP). A serodiagnostic assay was developed for monitoring sea turtle populations for CFPHV exposure. CFPHV glycoprotein H (gH) expressed in recombinant baculovirus was used in an enzyme-linked immunosorbent assay (ELISA) to detect virus-specific 7S turtle antibodies. Using captive-reared green turtles (Chelonia mydas) with no history of virus exposure as "known negatives" and others with experimentally induced FP as "known positives," the assay had 100% specificity but low sensitivity, as seroconversion was detected in only half of the turtles bearing experimentally induced tumors. Antibodies were detected only in …

Genetic Structure And Breeding System In A Social Wasp And Its Social Parasite, Eric A. Hoffman, Jennifer L. Kovacs, Michael Ad Goodisman Jan 2008

Genetic Structure And Breeding System In A Social Wasp And Its Social Parasite, Eric A. Hoffman, Jennifer L. Kovacs, Michael Ad Goodisman

Faculty Bibliography 2000s

Background: Social insects dominate ecological communities because of their sophisticated group behaviors. However, the intricate behaviors of social insects may be exploited by social parasites, which manipulate insect societies for their own benefit. Interactions between social parasites and their hosts lead to unusual coevolutionary dynamics that ultimately affect the breeding systems and population structures of both species. This study represents one of the first attempts to understand the population and colony genetic structure of a parasite and its host in a social wasp system. Results: We used DNA microsatellite markers to investigate gene flow, genetic variation, and mating behavior of …

Genome-Wide Survey And Expression Profiling Of Ccch-Zinc Finger Family Reveals A Functional Module In Macrophage Activation, Jian Liang, Wenjun Song, Gail Tromp, Pappachan E. Kolattukudy, Mingui Fu

Faculty Bibliography 2000s

Previously, we have identified a novel CCCH zinc finger protein family as negative regulators of macrophage activation. To gain an overall insight into the entire CCCH zinc finger gene family and to evaluate their potential role in macrophage activation, here we performed a genome-wide survey of CCCH zinc finger genes in mouse and human. Totally 58 CCCH zinc finger genes in mouse and 55 in human were identified and most of them have not been reported previously. Phylogenetic analysis revealed that the mouse CCCH family was divided into 6 groups. Meanwhile, we employed quantitative real-time PCR to profile their tissue …

A Novel Ccch-Zinc Finger Protein Family Regulates Proinflammatory Activation Of Macrophages, Jian Liang, Jing Wang, Asim Azfer, Wenjun Song, Gail Tromp, Pappachan E. Kolattukudy, Mingui Fu Jan 2008

A Novel Ccch-Zinc Finger Protein Family Regulates Proinflammatory Activation Of Macrophages, Jian Liang, Jing Wang, Asim Azfer, Wenjun Song, Gail Tromp, Pappachan E. Kolattukudy, Mingui Fu

Faculty Bibliography 2000s

Activated macrophages play an important role in many inflammatory diseases. However, the molecular mechanisms controlling macrophage activation are not completely understood. Here we report that a novel CCCH-zinc finger protein family, MCPIP1, 2, 3, and 4, encoded by four genes, Zc3h12a, Zc3h12b, Zc3h12c, and Zc3h12d, respectively, regulates macrophage activation. Northern blot analysis revealed that the expression of MCPIP1 and MCPIP3 was highly induced in macrophages in response to treatment with lipopolysaccharide (LPS). Although not affecting cell surface marker expression and phagocytotic function, overexpression of MCPIP1 significantly blunted LPS-induced inflammatory cytokine and NO(2)radical anion. production as well as their gene expression. …

Fine Structure Characterization Of Zero-Valent Iron Nanoparticles For Decontamination Of Nitrites And Nitrates In Wastewater And Groundwater, Kuen-Song Lin, Ni-Bin Chang, Tien-Deng Chuang

Faculty Bibliography 2000s

The main objectives of the present study were to investigate the chemical reduction of nitrate or nitrite species by zero-valent iron nanoparticle (ZVIN) in aqueous solution and related reaction kinetics or mechanisms using fine structure characterization. This work also exemplifies the utilization of field emission-scanning electron microscope (FE-SEM), transmission electron microscopy (TEM), and x-ray diffraction (XRD) to reveal the speciation and possible reaction pathway in a very complex adsorption and redox reaction process. Experimentally, ZVIN of this study was prepared by sodium borohydride reduction method at room temperature and ambient pressure. The morphology of as-synthesized ZVIN shows that the nearly …

Chromosomal Evidence For A Putative Cryptic Species In The Gymnotus Carapo Species-Complex (Gymnotiformes, Gymnotidae), Susana Sr Milhomem, Julio C. Pieczarka, William Gr Crampton, Danillo S. Silva, Augusto Cp De Souza, Jaime R. Carvalho Jr., Cleusa Y. Nagamachi

Faculty Bibliography 2000s

Background: In this study we examined the karyotypes of morphologically indistinguishable populations of the electric knifefish Gymnotus carapo sensu stricto from the Eastern Amazon of Brazil. These were identified unambiguously on the basis of external morphology, meristics, and pigmentation. Results: Specimens from one of five localities exhibited a karyotype previously not documented for Gymnotus species in the Amazon basin: 2n = 40 (34M/SM+6ST/A). Samples from the other four localities exhibited a different karyotype: 2n = 42 (30M/SM+12ST/A), which we had previously described. Specimens from all five localities presented constitutive heterochromatin in the centromeric region of almost all chromosomes, including in …

Methyl Farnesoate Couples Environmental Changes To Testicular Development In The Crab Carcinus Maenas, G. P. C. Nagaraju, D. W. Borst Jan 2008

Methyl Farnesoate Couples Environmental Changes To Testicular Development In The Crab Carcinus Maenas, G. P. C. Nagaraju, D. W. Borst

Faculty Bibliography 2000s

Carcinus maenas males have two major color phases. Green-phase males molt frequently and tend to live in brackish estuaries during the summer. After becoming red-phase males, they molt infrequently, have higher mating success, and live in cooler, deeper water. We found profound differences between these two phases in the way salinity and temperature affect hemolymph levels of methyl farnesoate (MF), a hormone that affects crustacean reproduction. Few green-phase males ( < 10%) had detectable MF in 33 ppt seawater (SW) at 11 or 18 degrees C. By contrast, about 30% of the red-phase males had detectable MF at either temperature. After transfer to 5 ppt SW, none of the green-phase males had detectable MF at 11 degrees C whereas 100% of green-phase males did at 18 degrees C. By contrast, 100% of the red-phase males had detectable MF in 5 ppt SW at either temperature. At 11 degrees C, green-phase males had detectable MF after eyestalk ablation (ESA), showing that they can produce MF. There was no additional increase in MF levels when ESA animals of either color phase were transferred to 5 ppt SW, suggesting that the eyestalk is the primary regulator of the MF response to low salinity. MF levels of green-phase males were increased by injecting MF, by ESA, or by exposure to 5 ppt SW at 18 degrees C. The testicular index of these treated animals nearly doubled after two weeks. Our results strongly suggest that environmental conditions such as temperature and salinity, affect testicular development in this crab by changing its MF levels.

Faculty Bibliography 2000s

Background: A common SNP upstream of the INSIG2 gene, rs7566605 (g.- 10,1025G > C, Chr2:118,552,255, NT_022135.15), was reported to be associated with obesity (Body Mass Index, [BMI]) in a genome-wide association scan using the Framingham Heart Study but has not been reproduced in other cohorts. As BMI is a relatively insensitive measure of adiposity that is subject to many confounding variables, we sought to determine the relationship between the INSIG2 SNP and subcutaneous fat volumes measured by MRI in a young adult population. Methods: We genotyped the INSIG2 SNP rs7566605 in college-aged population enrolled in a controlled resistance-training program, (the Functional …

Species-Specific Diversity Of A Fixed Motor Pattern: The Electric Organ Discharge Of Gymnotus, Alejo Rodrìguez-Cattaneo, Ana Carolina Pereira, Pedro A. Aguilera, William G. R. Crampton, Angel A. Caputi

Faculty Bibliography 2000s

Understanding fixed motor pattern diversity across related species provides a window for exploring the evolution of their underlying neural mechanisms. The electric organ discharges of weakly electric fishes offer several advantages as paradigmatic models for investigating how a neural decision is transformed into a spatiotemporal pattern of action. Here, we compared the far fields, the near fields and the electromotive force patterns generated by three species of the pulse generating New World gymnotiform genus Gymnotus. We found a common pattern in electromotive force, with the far field and near field diversity determined by variations in amplitude, duration, and the degree …

Heat Stress In The Intertidal: Comparing Survival And Growth Of An Invasive And Native Mussel Under A Variety Of Thermal Conditions, Kimberly R. Schneider Jan 2008

Heat Stress In The Intertidal: Comparing Survival And Growth Of An Invasive And Native Mussel Under A Variety Of Thermal Conditions, Kimberly R. Schneider

Faculty Bibliography 2000s

In the rocky intertidal, organisms frequently experience a wide range of daily body temperatures depending on the stage of the tide and the time of day. In the intertidal, the thermal adaption of a species and its ability to invade a new region may be closely linked. In this research, the physiological effects of thermal stress in both low tide and high tide conditions are compared between Mytilus galloprovincialis, a worldwide mussel invader, and M. trossulus, a sibling species. In a seawater tank, mussels were exposed to one of three aerial temperature treatments (20, 25, 30 degrees C) in a …

Faculty Bibliography 2000s

The chloroplast bioreactor is an alternative to fermentation-based systems for production of vaccine antigens and biopharmaceuticals. We report here expression of the plague FIN fusion antigen in chloroplasts. Site-specific transgene integration and homoplasmy were confirmed by PCR and Southern blotting. Mature leaves showed the highest level of transgene expression on the third day of continuous illumination, with a maximum level of 14.8% of the total soluble protein. Swiss Webster mice were primed with adjuvant-containing subcutaneous (s.c.) doses of F1-V and then boosted with either adjuvanted s.c. doses (s.c. FIN mice) or unadjuvanted oral doses (oral F1-V mice). Oral FIN mice …

Men Who Have Sex With Men And Recruit Bareback Sex Partners On The Internet: Implications For Sti And Hiv Prevention And Client Education, Christopher W. Blackwell Jan 2008

Men Who Have Sex With Men And Recruit Bareback Sex Partners On The Internet: Implications For Sti And Hiv Prevention And Client Education, Christopher W. Blackwell

Faculty Bibliography 2000s

Men who have sex with men (MSM) frequently use Internet-based Web sites to recruit sex partners. Although many MSM users of such sites advocate for safe sex practices in their personal profiles, some users actively recruit sexual partners who wish to participate in anal sexual intercourse without the use of condoms, also known as "bareback" sex. Participating in this sexual practice places both sexual partners at higher risk of HIV transmission. In addition, data indicate this behavior is associated with other high-risk activities such as drug use and communication of other sexually transmitted infections. This article summarizes the literature assessing …

Hatching Asynchrony Occurs As A Byproduct Of Maintaining Egg Viability, Robert Aldredge Jan 2008

Hatching Asynchrony Occurs As A Byproduct Of Maintaining Egg Viability, Robert Aldredge

Electronic Theses and Dissertations

For many organisms, embryonic development begins directly after an egg (ovum) has been fertilized by sperm; however, some organisms delay the onset of embryonic development until conditions are favorable for raising young. This delayed onset of development could occur by delaying implantation of fertilized ovum on the uterine wall, as seen in many mammals. Birds delay embryonic development by laying a set of fertilized ova over a period of consecutive days. These fertilized ova are protected from the ambient environment by an exterior shell, and it is in this shell outside of the female s body that embryonic development occurs, …

The Distribution, Abundance, And Habitat Use Of The Big Cypress Fox Squirrel, (Sciurus Niger Avicennia)., Danielle Munim Jan 2008

The Distribution, Abundance, And Habitat Use Of The Big Cypress Fox Squirrel, (Sciurus Niger Avicennia)., Danielle Munim

Electronic Theses and Dissertations

Human population growth and development reduce the area and quality of natural communities and lead to a reduction of populations of the species associated with them. Certain species can be useful indicators or "focal species" for determining the quality of ecosystem remnants and the required management practices. Tree squirrels are good models for studies on the effects of fragmentation because they depend on mature forests. The Big Cypress fox squirrel, (Sciurus niger avicennia), a state-listed Threatened subspecies endemic to south Florida, appears sensitive to habitat fragmentation and fire regime. This research aims to assess the conservation status of the Big …

Determination Of The Degradation Mechanism For Polychlorinated Biphenyl Congeners Using Mechanically Alloyed Magnesium/Palladium, Robert Devor Jan 2008

Determination Of The Degradation Mechanism For Polychlorinated Biphenyl Congeners Using Mechanically Alloyed Magnesium/Palladium, Robert Devor

Electronic Theses and Dissertations

Polychlorinated biphenyls are a ubiquitous environmental contaminant that can be found today throughout the world in soils and sediments, lakes and rivers, and flora and fauna. PCBs have percolated throughout the food chain, so that almost every human being has a detectable amount of the contaminant within their blood stream. Existing remediation methods include incineration, dredging and landfilling, and microbial degradation, but all of these methods have drawbacks that limit their effectiveness as treatment options. Recently, the use of zero-valent metals as a means of reductive dechlorination has been explored. Using a combination of zero-valent magnesium and catalytic palladium, a …

Using Stable Isotopes To Assess Population Structure And Feeding Ecology Of North Pacific Humpback Whales (Megaptera Novaeangliae), Briana Witteveen Jan 2008

Using Stable Isotopes To Assess Population Structure And Feeding Ecology Of North Pacific Humpback Whales (Megaptera Novaeangliae), Briana Witteveen

Electronic Theses and Dissertations

The North Pacific humpback whale (Megaptera novaeangliae) is a wide-ranging baleen whale species with a complex life history and population structure. As seasonal migrants, humpback whales are known to inhabit cooler, high-latitude waters when foraging and low-latitudes for mating and calving. Beyond this general migratory pattern, a number of demographic characteristics including, abundance, distribution, seasonal occurrence, and prey preferences remain unknown or poorly described. A complete understanding of humpback whale ecology is therefore lacking. Many methods used to explore these aspects of cetacean ecology are either prohibitively expensive or limited in the scope of what can be learned from their …

The Spiritual Competency Scale: A Comparison To The Aservic Spiritual Competencies, Linda Robertson Jan 2008

The Spiritual Competency Scale: A Comparison To The Aservic Spiritual Competencies, Linda Robertson

Electronic Theses and Dissertations

Spiritual and religious beliefs are significant aspects of a person's worldview and have been well established within many disciplines as a resource for physical and mental health. Therefore, they are relevant topics for counselors. The governing bodies of the counseling profession support the discussion of these beliefs in counseling. To meet the ethical mandates for competency in this area, the Association for Spiritual, Ethical, and Religious Values in Counseling (ASERVIC) produced the Spiritual Competencies. Despite these efforts, spiritual and religious material continues to be neglected in counselor training programs. In the absence of a formal measure of spiritual competency, curricular …

Multimedia Computer-Based Training And Learning: The Role Of Referential Connections In Supporting Cognitive Learning Outcomes, Sandro Scielzo Jan 2008

Multimedia Computer-Based Training And Learning: The Role Of Referential Connections In Supporting Cognitive Learning Outcomes, Sandro Scielzo

Electronic Theses and Dissertations

Multimedia theory has generated a number of principles and guidelines to support computer-based training (CBT) design. However, the cognitive processes responsible for learning, from which these principles and guidelines stem from, are only indirectly derived by focusing on cognitive learning outcome differences. Unfortunately, the effects that cognitive processes have on learning are based on the assumption that cognitive learning outcomes are indicative of certain cognitive processes. Such circular reasoning is what prompted this dissertation. Specifically, this dissertation looked at the notion of referential connections, which is a prevalent cognitive process that is thought to support knowledge acquisition in a multimedia …
