Synthesis And Evaluation Of Azetidinone Analogues Of Combretastatin A-4 As Tubulin Targeting Agents, Niamh O'Boyle, Miriam Carr, Lisa M. Greene, Orla Bergin, Seema M. Nathwani, Thomas Mccabe, David G. Lloyd, Daniela M. Zisterer, Mary J. Meegan

Articles

The synthesis and antiproliferative activity of a new series of rigid analogues of combretastatin A-4 are described which contain the 1,4-diaryl-2-azetidinone (β-lactam) ring system in place of the usual ethylene bridge present in the natural combretastatin stilbene products. These novel compounds are also substituted at position 3 of the β-lactam ring with an aryl ring. A number of analogues showed potent nanomolar activity in human MCF-7 and MDA-MB-231 breast cancer cell lines, displayed in vitro inhibition of tubulin polymerization and did not cause significant cytotoxicity in normal murine breast epithelial cells. 4-(4-Methoxyaryl)-substituted compound 32, 4-(3-hydroxy-4-methoxyaryl)-substituted compounds 35 and 41 and …

Experiences And Perceptions Of How Community-Based Interventions Can Promote Young Adults' Resilience To Suicide Within Rural/Regional Communities, Tracy Evans Jan 2010

Experiences And Perceptions Of How Community-Based Interventions Can Promote Young Adults' Resilience To Suicide Within Rural/Regional Communities, Tracy Evans

Theses : Honours

In the literature, both statistics and studies have noted that suicide in rural/regional young adults' is an important concern. Recent research suggests, that to facilitate a primary approach to suicide prevention in young people, there is a need to promote the protective construct of resilience at a community level, highlighting strategies such as connectedness, and decreasing the stigma related to mental illness and health-seeking behaviour (Commonwealth Department of Health & Aged Care, 2005; Injury Control Council of Western Australia, 2006). However, there is a need to investigate and identify the links or mediating factors that promote individual resilience within a …

Resilience In Families With Same-Sex Parents, Natasha Griffiths Jan 2010

Resilience In Families With Same-Sex Parents, Natasha Griffiths

Theses : Honours

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 (n = 10) raising children in Perth, Western Australia were interviewed. A thematic analysis technique outlined by Glesne …

Fear Of Terrorism: Legislation And Perceived Loss Of Civil Liberties, Finola Richardson Jan 2010

Fear Of Terrorism: Legislation And Perceived Loss Of Civil Liberties, Finola Richardson

Theses : Honours

Terrorism is a fear-inducing element of the current Australian political agenda. There are concerns about counter-terrorism legislation employed in Australian since the September 11th attacks on the United States, (9/11) and the effects these laws have on the civil liberties of Australian citizens. The literature presents two views one identifies the low risk of terrorism in Australia as no justification for strict new legislation. An alternative claim is increased security following 9/11 is essential in ensuring Australia is not viewed as a 'soft target'. The psychological experience of fear following terrorist attacks can influence the public's response to Government initiatives …

Autonomy Support In Australian Higher Education: A Review Of Contextual And Situational Applications Of Self-Determination Theory, Nicolas Connault Jan 2010

Autonomy Support In Australian Higher Education: A Review Of Contextual And Situational Applications Of Self-Determination Theory, Nicolas Connault

Theses : Honours

Self-Determination Theory (SDT, Deci & Ryan, 2000) is a macro-theory of motivation that has received much support from empirical research in the last twenty years. One of its main tenets is that the satisfaction of three basic psychological needs-autonomy, competence and relatedness-is universally required for the attainment of optimal psychological well-being, health, growth and self-determined behaviour. Higher education in Australia, through its outcomes-based approach to academic success, is not typically designed to promote student autonomy. Self-Determination Theory posits that promoting students' autonomy should lead to better quality of learning, higher intrinsic motivation to study, lower attrition and enhanced subjective well-being. …

Historically And In The Context Of Globalisation, How Do Western European Perceptions Of Folk/ Traditional Dance Pervade And Shape The Field Of Dance?, Emma Fishwick Jan 2010

Historically And In The Context Of Globalisation, How Do Western European Perceptions Of Folk/ Traditional Dance Pervade And Shape The Field Of Dance?, Emma Fishwick

Theses : Honours

With the international dance community becoming increasingly globalised, how do Western European perceptions of folk/ traditional dance pervade and shape the field of dance? This paper will discuss Western European perspectives towards traditional and folk dance and investigate the origins of such perspectives, if they do indeed exist. In doing so the reasoning of Western European perspectives will be examined, considered and questioned alongside that of non-Western European perspectives. The thesis is compiled from a wide range of textual sources that explore Western European world views in relation to non-Western European perspectives to argue that such perspectives do, to a …

The Experiences Of Incarceration On Indigenous Parents And Primary Care-Givers Of Juvenile Detainees, Simone Reid Jan 2010

The Experiences Of Incarceration On Indigenous Parents And Primary Care-Givers Of Juvenile Detainees, Simone Reid

Theses : Honours

Incarceration impacts on a number of people, not just the person sentenced. It has been suggested that the family of the prisoner can experience the prison sentence just as much, albeit differently, as the prisoner themself. Families remain important, as those prisoners who return to strong family networks are at less risk of recidivism. National research has been used to inform policy-makers, but every State has unique characteristics. The overrepresentation of Torres Strait Islander and Aboriginal juveniles in juvenile detention, especially in Western Australia, has been well-documented. However, research examining the experiences of incarceration on family members is limited. This …

Fairness, Justice And An Individual Basis For Public Policy, Douglas R. Oxley Jan 2010

Fairness, Justice And An Individual Basis For Public Policy, Douglas R. Oxley

Department of Political Science: Dissertations, Theses, and Student Research

Prior models of the policy process have examined how human characteristics can affect policy decision-making in such a way that it leads to aggregate effects on policy outcomes as a whole. I develop a model of the policy process which suggests that emotions related to fair and unfair experiences in the same policy domain are utilized by decision-makers as policy criteria. In the lab, I empirically tested this, and find that emotions and experience related to fairness do influence the policy decision to move away from the status quo alternative. Based upon this result, I simulated the evolution of a …

National Drought Mitigation Center: Faculty Publications

Increasing surface temperatures and climatic variability associated with global climate change are expected to produce more frequent and intense heat waves and droughts in many parts of the world. Our goal was to elucidate the fundamental, but poorly understood, effects of these extreme weather events on avian communities across the conterminous United States. Specifically, we explored: (1) the effects of timing and duration of heat and drought events, (2) the effects of jointly occurring drought and heat waves relative to these events occurring in isolation, and (3) how effects vary among functional groups related to nest location and migratory habit, …

Collapse Of The Maya: Could Deforestation Have Contributed?, Robert J. Oglesby, Thomas L. Sever, William Saturno, David J. Erickson Iii, Jayanthi Srikishen Jan 2010

Collapse Of The Maya: Could Deforestation Have Contributed?, Robert J. Oglesby, Thomas L. Sever, William Saturno, David J. Erickson Iii, Jayanthi Srikishen

Department of Earth and Atmospheric Sciences: Faculty Publications

The collapse of the Maya civilization during the ninth century A.D. is a major conundrum in the history of mankind. This civilization reached a spectacular peak but then almost completely collapsed in the space of a few decades. While numerous explanations have been put forth to explain this collapse, in recent years, drought has gained favor. This is because water resources were a key for the Maya, especially to ensure their survival during the lengthy dry season that occurs where they lived. Natural drought is a known, recurring feature of this region, as evidenced by observational data, reconstructions of past …

Partner Violence During Pregnancy: Prevalence, Effects, Screening, And Management, Beth A. Bailey

ETSU Faculty Works

The purpose of this review is to provide an overview of the current state of knowledge regarding the experience of intimate partner violence (IPV) during pregnancy. Pregnancy IPV is a significant problem worldwide, with rates varying significantly by country and maternal risk factors. Pregnancy IPV is associated with adverse newborn outcomes, including low birth weight and preterm birth. Many mechanisms for how IPV may impact birth outcomes have been proposed and include direct health, mental health, and behavioral effects, which all may interact. Screening for IPV during pregnancy is essential, yet due to time constraints and few clear recommendations for …

Mitochondrial Function As A Determinant Of Life Span, Ian R. Lanza, K. S. Nair Jan 2010

Mitochondrial Function As A Determinant Of Life Span, Ian R. Lanza, K. S. Nair

ETSU Faculty Works

Average human life expectancy has progressively increased over many decades largely due to improvements in nutrition, vaccination, antimicrobial agents, and effective treatment/prevention of cardiovascular disease, cancer, etc. Maximal life span, in contrast, has changed very little. Caloric restriction (CR) increases maximal life span in many species, in concert with improvements in mitochondrial function. These effects have yet to be demonstrated in humans, and the duration and level of CR required to extend life span in animals is not realistic in humans. Physical activity (voluntary exercise) continues to hold much promise for increasing healthy life expectancy in humans, but remains to …

Categorizing The Resistance Of Soybean Genotypes To The Soybean Aphid (Hemiptera: Aphididae), L. M. Pierson, Tiffany Heng-Moss, Thomas E. Hunt, J. C. Reese

Department of Entomology: Faculty Publications

We evaluated selected soybean, Glycine max (L.) Merr., genotypes during their reproductive stages for resistance to the soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), under greenhouse conditions and documented the categories of aphid-resistant soybean. Two screening studies were performed to assess the level of resistance to the soybean aphid on six soybean genotypes during the reproductive stages of development. Significant differences in aphid damage ratings were detected among the soybean evaluated in the screening studies. Three genotypes (KS4202, K-1639-2, and K1621) were considered moderately resistant based on the assessed damage ratings. Two of these genotypes (K-1639-2 and KS4202), along with …

Biotic And Abiotic Influences On Within-Plant Distribution Of Soybean Aphid (Hemiptera: Aphididae: Aphis Glycines), Tierney R. Brosius, Leon G. Higley, Thomas E. Hunt Jan 2010

Biotic And Abiotic Influences On Within-Plant Distribution Of Soybean Aphid (Hemiptera: Aphididae: Aphis Glycines), Tierney R. Brosius, Leon G. Higley, Thomas E. Hunt

Department of Entomology: Faculty Publications

The within-plant distribution of soybean aphid, Aphis glycines Matsumura has been attributed to various causes, yet it is unclear which factor or combination of factors most influence aphid within-plant distribution. Understanding soybean aphid distribution within the soybean canopy is important both in developing sampling programs and in evaluating injury. Because natural enemies have the potential to alter aphid dispersion, we examined how within-plant distribution of soybean aphid was influenced by different natural enemies. Field cages of different mesh diameters were used to exclude different sizes of natural enemies from aphid infested plots. Plots were surveyed and both natural enemy density …

Rna Interference As A Method For Target-Site Screening In The Western Corn Rootworm, Diabrotica Virgifera Virgifera, Analiza P. Alves, Richard W. Beeman, Marce D. Lorenzen, John E. Foster, Blair D. Siegfried

Department of Entomology: Faculty Publications

To test the efficacy of RNA interference (RNAi) as a method for target-site screening in Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae) larvae, genes were identified and tested for which clear RNAi phenotypes had been identified in the Coleopteran model, Tribolium castaneum. Here the cloning of the D. v. vergifera orthologs of laccase 2 (DvvLac2) and chitin synthase 2 (DvvCHS2) is reported. Injection of DvvLac2-specific doublestranded RNA resulted in prevention of post-molt cuticular tanning, while injection of DvvCHS2- specific dsRNA reduced chitin levels in midguts. Silencing of both DvvLac2 and DvvCHS2 was confirmed by RT-PCR and quantitative RT-PCR. As in T. …

Vidyaranya Swami's "Pañca Viveka" And Thomas Aquinas' "Quinque Viae" In The Light Of Today's Science, Klaus K. Klostermaier

Journal of Hindu-Christian Studies

In the context of recent attempts to shore up atheism with philosophical and scientific arguments the construction of rational proofs for the existence of God is receiving renewed attention. Over against the assertion of some scientists that religious belief is both unscientific and irrational, philosophers and theologians argue that the study of nature itself offers a great deal of evidence for the existence of a Creator. They are supported by numerous reputable scientists, the authors of book titles like The Language of God or The Mind of God and many others. it is noteworthy that Google has over two million …

Data Compression Concepts And Algorithms And Their Applications To Bioinformatics, Ozkan U. Nalbantoglu, David J. Russell, Khalid Sayood Jan 2010

Data Compression Concepts And Algorithms And Their Applications To Bioinformatics, Ozkan U. Nalbantoglu, David J. Russell, Khalid Sayood

Department of Electrical and Computer Engineering: Faculty Publications

Data compression at its base is concerned with how information is organized in data. Understanding this organization can lead to efficient ways of representing the information and hence data compression. In this paper we review the ways in which ideas and approaches fundamental to the theory and practice of data compression have been used in the area of bioinformatics. We look at how basic theoretical ideas from data compression, such as the notions of entropy, mutual information, and complexity have been used for analyzing biological sequences in order to discover hidden patterns, infer phylogenetic relationships between organisms and study viral …

The Prospects For Sequencing The Western Corn Rootworm Genome, Nicholas Miller, S. Richards, T. W. Sappington Jan 2010

The Prospects For Sequencing The Western Corn Rootworm Genome, Nicholas Miller, S. Richards, T. W. Sappington

Department of Entomology: Faculty Publications

Historically, obtaining the complete sequence of eukaryotic genomes has been an expensive and complex task. For this reason, efforts to sequence insect genomes have largely been confined to model organisms, species that are important to human health and representative species from a few insect orders. This situation is set to change as a number of ‘next generation’ sequencing technologies are making largescale DNA sequencing both affordable and accessible. Sequencing the genome of the western corn rootworm, Diabrotica virgifera virgifera, is likely to become a realistic proposition within the next 2 years. In the meantime, there is an active community …

Morphological And Genetic Analyses In The Melanoplus Packardii Group (Orthoptera: Acrididae), Mathew L. Brust, Erica J. Lindroth, W. Wyatt Hoback, Robert Wright, Kathryn J. Hanford, John E. Foster Jan 2010

Morphological And Genetic Analyses In The Melanoplus Packardii Group (Orthoptera: Acrididae), Mathew L. Brust, Erica J. Lindroth, W. Wyatt Hoback, Robert Wright, Kathryn J. Hanford, John E. Foster

Department of Entomology: Faculty Publications

Melanoplus packardii Scudder was described in 1897. Three additional closely-related species were later described and their status as species has been questioned on numerous occasions. We examined morphology from specimens collected in Nebraska which fit descriptions of three of the four forms and specimens that appeared to be hybrids. We found distinct morphological characters suggesting species status for M. foedus and M. packardii, but not for M. foedus fluviatilis. Examination of aedeagi of these three forms suggests that M. foedus and M. packardii are each distinct, but that the aedeagi of M. f. fluviatilis and M. f. foedus cannot …
