Subtidal Macroalgal Richness, Diversity And Turnover, At Multiple Spatial Scales, Along The Southwestern Australian Coastline, David Smale, G Kendrick, Thomas Wernberg Jan 2011

Subtidal Macroalgal Richness, Diversity And Turnover, At Multiple Spatial Scales, Along The Southwestern Australian Coastline, David Smale, G Kendrick, Thomas Wernberg

Research outputs 2011

Patterns of species richness are governed by processes that act at vastly different spatial scales. In the marine system of southwest Australia, macroalgal assemblage structure and richness is thought to be strongly influenced by both the Leeuwin Current, which acts at large regional spatial scales, and small-scale processes such as competition, wave disturbance and habitat heterogeneity. We examined macroalgal species richness and diversity at multiple spatial scales using a three-factor hierarchal design. Spatial extents ranged from metres (between quadrats) to many hundreds of kilometres (between regions), and the study encompassed almost 2000 km of temperate coastline. Macroalgal assemblages were highly …

Psychologists' Understanding Of Resilience: Implications For The Discipline Of Psychology And Psychology Practice, Lynne Cohen, Julie Ann Pooley, Catherine A. Ferguson, Craig A. Harms

Research outputs 2011

Current adoptions of strength-based approaches, as suggested by the positive psychology movement, asks professionals to develop different perspectives on familiar constructs. Given that we have little understanding how psychologists define and work with psychological phenomena, this current study sought to determine how Western Australian registered psychologists understand resilience. The 213 participants were asked to provide definitions and information about their understanding of resilience via an open-ended questionnaire. Demographic questions included the level and year ofqualification(s) and nature of psychological work undertaken. The definitions obtained from the participants were rated against definitions of resilience in the literature. The participants understandings of …

Resilience In Families With Same-Sex Parents [Journal Article], Natasha Griffiths, Julie Ann Pooley Jan 2011

Resilience In Families With Same-Sex Parents [Journal Article], Natasha Griffiths, Julie Ann Pooley

Research outputs 2011

Research suggests resilience can be viewed as a dynamic process facilitating positive functioning within the context of significant adversity. A nuclear family type that remains a controversial and stigmatized group is families with same-sex parents. Same sex families face a great number of challenges, due to the presence of heterosexism in society and they are often heavily criticised within the broad public domain. The current study adopted a phenomenological methodology to identify the family resilience processes utilised by same-sex families. Five lesbian couples raising children in Perth, Western Australia were interviewed. A thematic analysis technique was then conducted. Seven family …

Assessing Practical Laboratory Skills In Undergraduate Molecular Biology Courses, Lynne Hunt, Annette Koenders, Vidar Gynnild Jan 2011

Assessing Practical Laboratory Skills In Undergraduate Molecular Biology Courses, Lynne Hunt, Annette Koenders, Vidar Gynnild

Research outputs 2011

This study explored a new strategy of assessing laboratory skills in a molecular biology course to improve: student effort in preparation for and participation in laboratory work; valid evaluation of learning outcomes; and students’ employment prospects through provision of evidence of their skills. Previously, assessment was based on written laboratory reports and examinations, not on the demonstration of practical skills per se. This action research project involved altering the assessment design so that a greater proportion of the marks was allocated to active participation and learning in the laboratory, partially replacing a single examination with direct observation of student participation …

Correlating The Developmental Test Of Visual Perception -2 (Dtvp And The Test Of Visual Perceptual Skills - Revised (Tvps-R) As Assesssment Tools For Learners With Learning Difficulties, Janet Richmond, K Holland

Research outputs 2011

Learners are often referred to occupational therapists to assess their visual perceptual functioning. It is, therefore, imperative that the occupational therapists use the best assessment tools to obtain accurate and reliable results that lead to effective intervention which will be noticeable in the classroom functioning of these learners. A study was therefore conducted which correlated the results of the Developmental Test of Visual Perception (second edition) (DTVP-2) and the Test of Visual Perceptual Skills Revised (TVPS-R) in a cohort of 173 learners from Grade 1 to Grade 4 (children aged 6 years to 11 years). The learners attend a remedial …

From Isotropic To Anisotropic Side Chain Representations: Comparison Of Three Models For Residue Contact Estimation, Weitao Sun, Jing He Jan 2011

From Isotropic To Anisotropic Side Chain Representations: Comparison Of Three Models For Residue Contact Estimation, Weitao Sun, Jing He

Computer Science Faculty Publications

The criterion to determine residue contact is a fundamental problem in deriving knowledge-based mean-force potential energy calculations for protein structures. A frequently used criterion is to require the side chain center-to-center distance or the C-alpha-to-C-alpha atom distance to be within a pre-determined cutoff distance. However, the spatially anisotropic nature of the side chain determines that it is challenging to identify the contact pairs. This study compares three side chain contact models: the Atom Distance criteria (ADC) model, the Isotropic Sphere Side chain (ISS) model and the Anisotropic Ellipsoid Side chain (AES) model using 424 high resolution protein structures in the …

Computational Network Analysis Of The Anatomical And Genetic Organizations In The Mouse Brain, Shuiwang Ji Jan 2011

Computational Network Analysis Of The Anatomical And Genetic Organizations In The Mouse Brain, Shuiwang Ji

Computer Science Faculty Publications

Motivation: The mammalian central nervous system (CNS) generates high-level behavior and cognitive functions. Elucidating the anatomical and genetic organizations in the CNS is a key step toward understanding the functional brain circuitry. The CNS contains an enormous number of cell types, each with unique gene expression patterns. Therefore, it is of central importance to capture the spatial expression patterns in the brain. Currently, genome-wide atlas of spatial expression patterns in the mouse brain has been made available, and the data are in the form of aligned 3D data arrays. The sheer volume and complexity of these data pose significant challenges …

Transitions In Midlife Women's Lives: Contemporary Experiences, Julie Dare Jan 2011

Transitions In Midlife Women's Lives: Contemporary Experiences, Julie Dare

Research outputs 2011

In this article I report on a research project conducted in Perth, Western Australia, which investigated how contemporary women experience physiological and psychosocial midlife transitions. Qualitative in-depth interviews explored the challenges confronting women during this period. In doing so, continuities and divergences that exist between existing literature on midlife transitions and women's own perspectives are highlighted. Based on key findings, I suggest that while most women manage the “classic” transitions of menopause and the “empty nest” relatively well, the impact of divorce and the aging and death of parents present more serious long-term challenges to women.

Security Risk Management: A Psychometric Map Of Expert Knowledge Structure, David Brooks Jan 2011

Security Risk Management: A Psychometric Map Of Expert Knowledge Structure, David Brooks

Research outputs 2011

The security industry operates within a diverse and multi-disciplined knowledge base, with risk management as a fundamental knowledge domain within security to mitigate its risks. Nevertheless, there has been limited research in understanding and mapping security expert knowledge structures within security risk management to consider if parts of security risk management are unique from more general risk management. This interpretive study applied a technique of multidimensional scaling (MDS) to develop and present a psychometric map within the knowledge domain of security risk management, validated with expert interviews. The psychometric MDS security risk management concept map presented the expert knowledge structure …

Multivariate Anti-Inflammatory Approaches To Rescue Neurogenesis And Cognitive Function In Aged Animals, Sandra Antonieta Acosta Jan 2011

Multivariate Anti-Inflammatory Approaches To Rescue Neurogenesis And Cognitive Function In Aged Animals, Sandra Antonieta Acosta

USF Tampa Graduate Theses and Dissertations

Studies have shown that there is a strong correlation between aging and neurodegenerative diseases. Aging is considered the number one risk factor to develop neuropathologies such as memory loss, senile dementia, Alzheimer's disease (AD), and Parkinson's disease. Neurodegenerative diseases tend to start during adulthood, and aggravate over time, making them difficult to prevent and to treat. In the Unites States, demographic studies by U.S. Bureau of the Census have determined that our aging population of >65 years is expected to increase from the present 35 million to 78 million in 2030. This would result, not only to an increase of …

Children Who Die Of Abuse: An Examination Of The Effects Of Perpetrator Characteristics On Fatal Versus Non-Fatal Child Abuse, Donald L. Dixon Jan 2011

Children Who Die Of Abuse: An Examination Of The Effects Of Perpetrator Characteristics On Fatal Versus Non-Fatal Child Abuse, Donald L. Dixon

USF Tampa Graduate Theses and Dissertations

Approximately 2000 children die annually in the United States from abuse and neglect, but the interplay of factors such as perpetrator characteristics and family composition which place these children at risk have not been wellestablished. The review of the literature focuses on the correlation between child deaths resulting from abuse and perpetrator characteristics most associated with these deaths. Characteristics such as the perpetrator’s age, race/ethnicity, gender, alcohol and substance use/abuse and/or sale, and prior history of abuse are among those examined. Additionally, these factors are examined within ecological and risk and protective factor theoretical frameworks. It is argued that further …

Spider Cognition, Robert R. Jackson, Fiona R. Cross Jan 2011

Spider Cognition, Robert R. Jackson, Fiona R. Cross

All Peer-Reviewed Publications

Spiders, having minute brains, were once considered simple, instinct-driven automatons, but research on spider biology is revealing increasing evidence of their cognitive abilities. In this review, we discuss the complex, flexible behaviour of spiders, especially salticids, and highlight how sometimes the cognitive character of spider behaviour closely parallels that of much bigger animals. This includes the use of selective attention (both visual and olfactory) and the use of planned detours. The implications of these findings, and how they relate to bigger issues traditionally associated with big-brain animals, such as 'representation' and 'mind', are discussed. Also discussed are issues relating to …

Dissemination Of Entomopathogenic Fungi Using Busseola Fusca Male As Vector, Nguya K. Maniania, Elizabeth Ouna, Peter Ahuya, Brigitte Frérot, Anne Emmanuelle Félix, Bruno Le Ru, Paul André Calatayud

All Peer-Reviewed Publications

The stem borer, Busseola fusca (Fuller), is an important pest of maize Zea mays L. and sorghum Sorghum bicolor (L.) in eastern and southern Africa. To control this pest, biological control methods including the use of entomopathogenic fungi are being considered. The pathogenicity of one isolate of Metarhizium anisopliae (Metsch.) Sorok. and one isolate of Beauveria bassiana Bals. (Vuill.) were first tested on different developmental stages of B. fusca including eggs, neonate, 2nd and 3rd-instar larvae. Both fungal isolates were pathogenic to all the stages tested. However, differences in mortality were observed among larvae that hatched from treated egg masses. …

Flexibility In The Foraging Strategies Of Spiders, Ximena J. Nelson, Robert R. Jackson Jan 2011

Flexibility In The Foraging Strategies Of Spiders, Ximena J. Nelson, Robert R. Jackson

All Peer-Reviewed Publications

Although many spiders build prey-capture webs, spider foraging strategies include species that, instead of building webs, deploy silk in other ways for prey capture. Additionally, there are species that capture prey, either by ambush or by active pursuit, without making notable use of silk in the process. There are striking examples of predatory specialisation from spiders, particularly among the Salticidae, suggesting that assumptions about adaptive trade-offs, in which the small nervous systems of spiders might constrain their cognitive or sensory abilities, need to be carefully evaluated. Predatory versatility, whereby an individual spider adopts a conditional strategy with which it classifies …

Interpopulation Variation In Kairomone Use By Cyrba Algerina, An Araneophagic Jumping Spider From Portugal, Ana M. Cerveira, Robert R. Jackson Jan 2011

Interpopulation Variation In Kairomone Use By Cyrba Algerina, An Araneophagic Jumping Spider From Portugal, Ana M. Cerveira, Robert R. Jackson

All Peer-Reviewed Publications

Geographic variation in a predator's reliance on kairomones from prey was investigated. The predator studied, Cyrbaalgerina, is an araneophagic (spider-eating) jumping spider (Salticidae) and the prey were oecobiid spiders (Oecobiidae). There were two study sites (Sintra and Tavira), both in Portugal. Oecobiusmachadoi was a common oecobiid in Sintra, but no oecobiids were found in Tavira. Staged encounters showed that oecobiid-specific prey-capture behaviour was adopted by the C. algerina in Sintra but not in Tavira. In experiments using a Y-shaped olfactometer, significantly more Sintra C. algerina individuals chose the side with oecobiid odour instead of the blank side when the odour …

Ecological Restoration Of Novel Lake Districts: New Approaches For New Landscapes, C. D. Mccullough, Eddie J. Van Etten

Research outputs 2011

Mine void pit lakes often contain water of poor quality with potential for environmental harm that may dwarf other mine closure environmental issues in terms of severity, scope, and longevity. This is particularly so when many pit lakes occur close together and thus form a new ‘‘lake district’’ landscape. Pit lakes that can be developed into healthy lake or wetland ecosystems as a beneficial end use provide opportunities for the mining industry to fulfil commitments to sustainability. Clearly articulated restoration goals and a strategic closure plan are necessary to ensure pit lake restoration toward a new, yet regionally-relevant, aquatic ecosystem, …

Children's Exposure To Metals: A Community-Initiated Study, Anna Carita Callan, Matthew Winters, Caroline Barton, Mary C. Boyce, Andrea Lee Hinwood

Research outputs 2011

In 2007, it was shown that the shipping of lead (Pb) through Esperance Port in Western Australia resulted in contamination and increased Pb concentrations in children. A clean-up strategy was implemented; however, little attention was given to other metals. In consultation with the community, a cross-sectional exposure study was designed. Thirty-nine children aged 1 to 12 years provided samples of hair, urine, drinking water, residential soil and dust. Concentrations of nickel (Ni) and Pb were low in biological and environmental samples. Hair aluminium (Al) (lower than the detection limit [DL] to 251 μg/g) and copper (Cu) (7 to 415 μg/g), …

The Effects Of Omega-3 Fatty Acids On Saccharomyces Cerevisiae Inositol Pathway Mutants, Daniel Antonio Colon Hidalgo, Marlene Murray-Nseula Jan 2011

The Effects Of Omega-3 Fatty Acids On Saccharomyces Cerevisiae Inositol Pathway Mutants, Daniel Antonio Colon Hidalgo, Marlene Murray-Nseula

Honors Theses

Bipolar disease is a severe and chronic debilitating mental disorder affecting 1-3% of the population. Omega-3-fatty acids have been shown to relieve symptoms of bipolar disorder and are not associated with the negative side effects of lithium and valproate, two of the commonly used drugs for treating this condition. The mechanism of action of omega-3-fatty acids remains unknown. Therefore the purpose of this study was to determine if, like lithium and valproate, omega-3-fatty acids affect inositol metabolism. This was accomplished by investigating the effect of the omega-3-fatty acid docosahexanoic acid (DHA) on the growth of inositol pathway mutants. To measure …

Dermal Reduction Of Urushiols Using An Activated Charcoal Formulated Dermal Care Patch, Celena Cameron Jan 2011

Dermal Reduction Of Urushiols Using An Activated Charcoal Formulated Dermal Care Patch, Celena Cameron

Honors Theses

For centuries, activated Charcoal (AC) has been used externally in a poultice form to adsorb "poisons" trapped in the outer layers of skin and internally to relieve intestinal discomfort and to remove toxic materials. The largest use for activated charcoal, in our society, is as a filter bed in air and water remediation cartridges. Recently, scientists have formulated AC into a nonstick dermal bandage called the Charcoal Patch (CP), but the adsorption properties are not well understood for this new formulation. Experiments have been conducted to see if these dermal bandages can be used to adsorb oils such as poison …

The Synthesis And Characterization Of Novel Imino Stilbenes, Shieun Jang Jan 2011

The Synthesis And Characterization Of Novel Imino Stilbenes, Shieun Jang

Honors Theses

We are in the process of developing a two-step synthesis of imino stilbenes as potential molecular switches, which are important in biology, electronics and other applications especially at nanoscopic scale. While both imines and stilbenes are well known, we have not uncovered any prior research and documentation on our proposed imino stilbenes in the scientific literature. In pursuit of our goal we have developed a new procedure for synthesis of t-butyl imines derived from aromatic aldehydes and ketones. We are also currently evaluating four different stilbene synthesis methods. Future work will systematically investigate the effect of electron withdrawing and donating …

Synthesis And Testing Of Second Generation Azatilbenes, Maurice Hardy Jan 2011

Synthesis And Testing Of Second Generation Azatilbenes, Maurice Hardy

Honors Theses

Based on previous research, azastilbenes have been reported as effective chemical sensors for organophosphates and organothiophosphates; they are related classes and the active components of agricultural pesticides, environmental pollutants and chemical warfare agents. This project builds on previous work and involves the synthesis of a variety of these azastilbenes and the testing of their respective properties. Azastilbene sensors are prepared using high-yield organic synthetic methodology developed in Professor Murray's lab. The next step involves testing the sensors through a measure, by UV-Vis spectroscopy and fluorometry, of an optical change upon the addition of analyte to a solution containing azastilbene sensor.

The Effects Of Valproate Prodrugs On The Inositol Biosynthetic Pathway In Saccharomyces Cerevisiae Yeast, Lisa Thompson Jan 2011

The Effects Of Valproate Prodrugs On The Inositol Biosynthetic Pathway In Saccharomyces Cerevisiae Yeast, Lisa Thompson

Honors Theses

Bipolar disorder is a psychiatric disorder characterized by episodes of abnormally elevated mood followed by periods of extreme depression. Currently, valproate is one of the drugs used to treat the disorder but it is associated with many negative side effects. The goal of this project is to create a prodrug with structural similarities to valproate and determine if its effect on growth of the yeast Saccharomyces cerevisiae is similar to that of valproate. Yeast cells were grown in media with or without the prodrug in the presence or absence of inositol. The results showed that the prodrug inhibited growth.

Non-Labeled, Real-Time Detection Of H1n1 Dna Hybridization Using Combined Qcm-D System, Sandra P. Prieto Jan 2011

Non-Labeled, Real-Time Detection Of H1n1 Dna Hybridization Using Combined Qcm-D System, Sandra P. Prieto

Honors Theses

Detection of H1N1 or other seasonal and highly contagious viruses are of vital importance, since early diagnosis from a patient's fluid, such as saliva, would accelerate treatment and containment of the flu. Current lab tests often require cumbersome labeling steps and several hours to detect the presence of viral DNAs. The QCM-D (quartz crystal microbalances with dissipation) technology was used to detect presence as well as distinguish H1N1 and H1N5 DNAs in real-time (a few minutes) with the use of relatively small sample volume (200-500 ul). Single stranded complementary H1N1 DNA was immobilized via Neutravidin-biotin linkage on a gold substrate …

The Role Of Ci(-) Channel-Inhibition In The Brain On The Phonotactic Selectivity Of Female Crickets, Brent H. Sherwin Jan 2011

The Role Of Ci(-) Channel-Inhibition In The Brain On The Phonotactic Selectivity Of Female Crickets, Brent H. Sherwin

Honors Theses

The goal of this project was to determine if picrotoxin influences phonotactic selectivity of female crickets when nanoinjected into the supraesophageal ganglion. Adult females of Acheta domesticus were pre-tested for phonotaxis on a treadmill to a range of calling songs with different syllable periods. Following dissection to expose the brain, 9.2 nL of either saline (control group) or 10-5 M picrotoxin (experimental group) was nanoinjected into the supraesophageal ganglion. Post-tests following saline injection (10 min later) were similar to the pre-tests. Picrotoxin-treated females became more phonotactically selective displaying a preference for calling songs with the shorter syllable periods.
