Graduate Theses, Dissertations, and Problem Reports (ETD)

Ailanthus altissima (Mill.) Swingle (tree of heaven) is an exotic species from China that was intentionally introduced as an urban ornamental species but has since become naturalized throughout much of the U.S. This pioneer species appears poised to invade rural areas as current rates of human-induced forest disturbance lower dispersal barriers and increase available habitat, especially in eastern forests, where it will compete with pioneer native trees such as Liriodendron tulipifera (L.) (yellow poplar). To compare the invasion potential of exotic A. altissima and native L. tulipifera, my research focused on two objectives. First, I investigated characteristics that influence dispersal …

Hostility, Forgiveness, And Cardiovascular Reactivity To Stress: Does Forgiveness Mediate Or Moderate The Relation Between Hostility And Cardiovascular Reactivity To Anger -Eliciting Laboratory Experiences?, Danielle H. Hernandez Jan 2005

Hostility, Forgiveness, And Cardiovascular Reactivity To Stress: Does Forgiveness Mediate Or Moderate The Relation Between Hostility And Cardiovascular Reactivity To Anger -Eliciting Laboratory Experiences?, Danielle H. Hernandez

Graduate Theses, Dissertations, and Problem Reports (ETD)

Numerous studies that have examined the physical health consequences of individual variables have focused on negative traits such as hostility, anger, and stress. These studies have demonstrated that such variables are often related to deleterious health outcomes as well as exaggerated cardiovascular reactions to stress. Fewer studies have examined the health benefits of positive variables like forgiveness. Forgiveness and hostility are thought to have an inverse relation, and it is not surprising that forgiveness has been associated with reduced cardiovascular reactivity to stress. Recognizing that hostility is related to elevated cardiovascular reactivity, and that forgiveness is associated with decreased cardiovascular …

Graph Algorithms For The Haplotyping Problem, Yunkai Liu Jan 2005

Graph Algorithms For The Haplotyping Problem, Yunkai Liu

Graduate Theses, Dissertations, and Problem Reports (ETD)

Evidence from investigations of genetic differences among human beings shows that genetic diseases are often the results of genetic mutations. The most common form of these mutations is single nucleotide polymorphism (SNP). A complete map of all SNPs in the human genome will be extremely valuable for studying the relationships between specific haplotypes and specific genetic diseases. Some recent discoveries show that the DNA sequence of human beings can be partitioned into long blocks where genetic recombination has been rare. Then, inferring both haplotypes from chromosome sequences is a biologically meaningful research topic, which has compounded mathematical and computational problems.;We …
