Evaluation of Theory for Identifying Populations for Genetic Improvement of Maize Hybrids

The ability to identify populations with the greatest chance for breeding success may increase the use of unadapted populations by concentration of resources on favorable germplasm. This study was conducted to evaluate the effectiveness of a method (estimates of \u27)for identifying maize (Zea mays L.) populations with the greatest number of dominant alleles at loci that are homozygous recessive in a single cross. This study also evaluates the effectiveness of a relationship estimator for detecting similarities between a population and the inbreds of a single cross. Estimates of and the relationship estimator were calculated by using donor populations of known composition and relationship to the recipient single cross. Six recipient single crosses were formed from the diallel cross of maize inbreds B73, B79, B77, and Mo17o Donor populations were composed of various proportions of inbreds B79 and B77. Estimates of correctly identified the population expected to have the largest number of unique dominant alleles in three of five single crosses (60%) for grain yield. for ear height, correctly identified the population expected to have the largest number of unique dominant alleles in four or five single crosses (80%). Estimates of did not identify populations expected to contain dominant alleles for earlier silking, suggesting that additive gene action or epistasis were important for siiking date. The relationship estimator for yield correctly identified the known relationship between the populations and the inbred parents of the single crosses. The successful application of to exotic populations is uncertain because of a low frequency of favorable dominant alleles contained by exotics for important economic traits

Giraffes, Ferris Wheels and Royal Reenactments: Hits and Misses in the Reinvention of a Joseon Palace

Thesis (M.A.) - Indiana University, East Asian Languages & Cultures (EALC, 2015)Tourist sites, like national identities, are selectively promoted depictions often made from highly contested perspectives. A site is a self-perpetuating scene created by host and visitors swapping the same images. Olivia Jenkins has described spiraling circles of representation linked to Australia’s iconic symbols, and Herbert Bix, Carol Gluck and Kosaku Yoshino have applied a similar logic to processes facilitating much greater shifts in the image of the entire nation of Japan. Success in both cases requires cropping pieces that do not fit into the newly evolved, prevalent narrative. The speed at which scenes have shifted at one palace in Seoul has meant entire buildings, a park full of fun rides, and one of Korea’s great works of literature – great at least from a Western-trained perspective -- are vanishing from collective memory. Such “a focus on small-scale or localized change can illustrate or embody much broader processes of political transformation,” as Katherine Verdery says, “the Macro is in the Micro.” Consequently this thesis examines manifestations of major changes in Korea’s governing and social structures reflected in the grounds of Changgyeonggung. Discourse and content analyses of guide books, brochures, and websites show how visitors come to absorb the conveniently condensed narratives and imagery as successive administrators place new monuments atop or alongside those of their predecessors to rewrite the geographic scenes

Experience without Memory: Optogenetics, the Self, and the Ethics of Forgetting

The horizon of clinical memory modification, long the domain of science fiction, is rapidly approaching; it is therefore imperative that we understand the ethical implications of such neuromodificatory technologies. We might begin such inquiry with the public’s worries about these technologies, namely that modifying memory will concomitantly modify the self. Yet, before discerning the reasonableness of this worry, we must understand the meaning of “the self” in relation to memory. Distilling this conception of the self is the principal aim of this thesis. I argue that many popular self-conceptions cannot capture our worries about neuromodification. Hence, I distill a novel such conception, which I call the Proustian Self—marshaling, to that end, not only neuroscientific evidence and metaphysical arguments but also literary-phenomenological analysis. I ultimately argue that this conception should be the target of further neuroethical inquiry regarding the prospect memory modification and its effects on putative patients
