Going The Distance: Themes Of The Hero In Disney's Hercules, Amy Elizabeth Burchfield Dec 2013

Going The Distance: Themes Of The Hero In Disney's Hercules, Amy Elizabeth Burchfield

Theses and Dissertations

Disney's Hercules is an apt modern reception of the ancient mythology of Herakles, acknowledging ancient and modern sources surrounding three types of classical hero: the archetypal hero, influenced by the ideas of Joseph Campbell; the Pan-Hellenic hero, distilled from ancient Greek exempla of heroism from epic and other genres of ancient literature; and the tragic hero, inspired by the heroic criteria presented in Aristotle's Poetics. By adapting these heroic types from their traditional ancient source myths, Disney's Hercules produces a new, contemporary definition of heroism—one informed by modern, Western family values. This adaptation renews the power of the myth of …

Better A Broader Diagnosis Than A Misdiagnosis: The Study Of A Neoplastic Condition In A Male Individual Who Died In Early 20th Century (Coimbra, Portugal), Carina Marques, Ana Luisa Santos, Eugénia Cunha

Anthropology Faculty Publications

The paleopathological record of neoplastic conditions in the past is considered scarce. The detection of tumours in ancient populations is hindered by the quality and quantity of signs visible on the skeleton, the methodological approach, the preservation of remains, and by difficulties of differential diagnosis. The aims of this paper are to report the extensive and multiple osteolytic lesions observed in an adult male and to discuss the possible etiology of these lesions. The individual, a 71-year-old male who died in 1932, is part of the Coimbra Identified Skeletal Collection. Records indicate that he died of a ‘heart lesion’. The …


Development Of A Field Test For Total Suspended Solids Analysis, Jessica Branigan Dec 2013

Development Of A Field Test For Total Suspended Solids Analysis, Jessica Branigan

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Total suspended solids (TSS) are all particles in water that will not pass through a glass fiber filter with a pore size less than 2 μm, including sediments, algae, nutrients, and metals. TSS is an important water quality parameter because of its adverse effects on aquatic species and wildlife. The EPA has proposed a regulation for turbidity, a related water quality parameter, which has been stayed pending further testing. TSS is regulated through the EPA via the NPDES in many states. Since there are no accepted field tests for TSS, projects with TSS regulations must send samples to a laboratory …


Ultrasonic Propagation And Scattering In Pearlitic Steel, Hualong Du Dec 2013

Ultrasonic Propagation And Scattering In Pearlitic Steel, Hualong Du

Department of Engineering Mechanics: Dissertations, Theses, and Student Research

Diffuse ultrasonic backscatter measurements have been especially useful for extracting microstructural information and for improving flaw detection in materials. In this dissertation, this approach is applied to inspection of railroad wheels. To improve the wear resistance, the tread surfaces of railroad wheels are usually quenched with water to increase the hardness. The pearlite phase of iron, characterized by alternating ferrite and cementite phases, is created by the quenching and the lamellar spacing within grains increases progressively from the quenched tread surface to deeper locations due to the non-uniform cooling rate. The quench depth is an important parameter governing the wheel …

The Costs Of Ambient Cultural Disharmony: Indirect Intercultural Conflicts In Social Environment Undermine Creativity, Roy Y. J. Chua Dec 2013

The Costs Of Ambient Cultural Disharmony: Indirect Intercultural Conflicts In Social Environment Undermine Creativity, Roy Y. J. Chua

Research Collection Lee Kong Chian School Of Business

Intercultural tensions and conflicts are inevitable in the global workplace. This paper introduces the concept of ambient cultural disharmony—indirect experience of intercultural tensions and conflicts in individuals' immediate social environment—and demonstrates how it undermines creative thinking in tasks that draw on knowledge from multiple cultures. Three studies (a network survey and two experiments) found that ambient cultural disharmony decreases individuals' effectiveness at connecting ideas from disparate cultures. Beliefs that ideas from different cultures are incompatible mediate the relationship between ambient cultural disharmony and creativity. Alternative mechanisms such as negative affect and cognitive disruption were not viable mediators. Although ambient cultural …

Integrated Soil Fertility Management: Aggregate Carbon And Nitrogen Stabilization In Differently Textured Tropical Soils, R. M. Gentile, B. Vanlauwe, J. Six

All Peer-Reviewed Publications

Soil organic matter is important to improve and sustain soil fertility in tropical agroecosystems. The combined use of organic residue and fertilizer inputs is advocated for its positive effects on short-term nutrient supply, but the effect of the integrated use on long-term stabilization of soil organic C and N is still unclear. We conducted a 1.5-y soil incubation experiment with maize (Zea mays) residue and urea fertilizer to examine the stabilization of C and N in four Sub-Saharan African soils differing in texture (sand, sandy loam, clay loam, and clay). The inputs were enriched with 13C and 15N in a …

No Promo Hetero: Children's Right To Be Queer, Clifford J. Rosky Dec 2013

No Promo Hetero: Children's Right To Be Queer, Clifford J. Rosky

Cardozo Law Review

This Article argues that the state has no legitimate interest in promoting heterosexuality or gender conformity during childhood. Although opponents of LGBT rights have longed cited this goal as one of the primary justifications for discrimination against LGBT people, it has no constitutional foundation upon which to stand.

Building upon a schema familiar to legal scholarship on LGBT rights, this Article challenges the state's interest in promoting heterosexuality in childhood by articulating a tripartite defense of children's homosexual speech, status, and conduct. It argues that these three aspects of children's homosexuality are connected to and protected by the Constitution's free …

Regional-Climate And Local-Microbial Controls On Ecosystem Processes During Grassland Restoration, Meredith Lynne Mendola Dec 2013

Regional-Climate And Local-Microbial Controls On Ecosystem Processes During Grassland Restoration, Meredith Lynne Mendola

Theses

Root productivity likely has consequences for the composition, activity, and recovery of soil microbial populations and the belowground processes mediated by these organisms. In tallgrass prairie, ecotypic variation potentially exists in response to a strong precipitation gradient across the Great Plains. Thus, ecotypic variation within a species may differentially affect belowground net primary productivity (BNPP), the associated soil microbial community, and may scale up to affect ecosystem processes. The goals of this study were to elucidate: (1) whether ecotype, environment, or an ecotype by environment interaction regulate BNPP of a dominant species (Andropogon gerardii) collected from and reciprocally planted in …
