The Economic Consequences of the Klassical Caricature

This essay is part of a wider investigation into the macroeconomic creation myth; and this introductory section provides only a very brief summary of Pigou\u27s work. The reader\u27s indulgence is therefore requested: full justification for my assertions will be provided in a forthcoming book. Limitations of space prohibit me from doing justice to my thesis about Pigou at the same time as addressing my allocated topic. ISBN: 978-0-7923-8149-

PHYLOGENOMICS, LIFE-HISTORY EVOLUTION AND TAXONOMY OF LEAF MINING MOTHS (LEPIDOPTERA: GRACILLARIOIDEA)

Phytophagous insects dominate the terrestrial earth. While many are external plant feeders, a large diversity of insects specialize on feeding internally within plants. This study constructs one of the first phylogenies of the diverse leaf-mining moth superfamily Gracillarioidea, and examines broad patterns of life history evolution. This dissertation begins with a short introduction (Chapter 1), before a molecular phylogenetic analysis of the Gracillarioidea utilizing over 14,800 nucleotides (Chapter 2). Results indicate that 1) Douglasiidae probably does not belong in Gracillarioidea; 2) the phylogenetic position of Bucculatricidae in Gracillarioidea is generally weak, but strong when non-synonymous changes are analyzed alone; 3) deep divergences in the superfamily are difficult to resolve even with 21 genes; and 4) four strongly supported clades, roughly corresponding to Kumata's classifications were recovered in the Gracillariidae. Chapter 3 is a preliminary examination of life-history evolution in Gracillariidae, focusing on the "top down" effects from parasitoids that may have shaped the life histories of gracillariids. Results include: 1) larval traits (larval habit, cocoon ornamentation) is conserved on phylogeny, but traits associated with hosts are less so; 2) that host shifts in gracillariids are more common among closely related plants, and that closely related insects feed on closely related hosts; 3) blotch mining is the ancestral condition of mine form in Gracillariidae; 4) tentiform blotch mining, a modification of the simple blotch mine, may be an evolutionary innovation against parasitoids. The final three chapters focus on the taxonomy, life-history, and morphology of several gracillariids, including the description of three new species. The central theme is Phyllocnistis, a diverse, yet poorly studied serpentine mining gracillariid genus

Nostalgia remix: fusing traditional crafts and contemporary interior product design

While always a fundamental part of the design world, textiles have only recently become more integrated into interior product design during the past few years. In particular this kind of exploration gives the product a hand-made authentic quality rooted in traditional craft history. The term “nostalgia remix” both taps current terms in the popular design media, and refers to a concept defined by Judith Cushman-Hammer, lecturer at the University of North Carolina at Greensboro. The term then suggests both an examination of the past and a contemplation of the future of product design. The intent of “nostalgic remix” design, or contemporary designs created with a traditional quality, is to evoke feelings of familiarity and awaken memories; to create products that have an emotional element connected to something recognizable from the past. The thesis investigation develops and evaluates a design process that fuses traditional craft techniques, such as sewing, quilting, and weaving, with contemporary interior product design. The "cocoon" line of products, created through a generative hands-on design process, consists of items intended to help create personal space, privacy, and comfort. This design process encompasses textile arts, or products with a textile component, specifically products that soften the environment

Propfan Test Assessment (PTA)

The objectives of the Propfan Test Assessment (PTA) Program were to validate in flight the structural integrity of large-scale propfan blades and to measure noise characteristics of the propfan in both near and far fields. All program objectives were met or exceeded, on schedule and under budget. A Gulfstream Aerospace Corporation GII aircraft was modified to provide a testbed for the 2.74m (9 ft) diameter Hamilton Standard SR-7 propfan which was driven by a 4475 kw (600 shp) turboshaft engine mounted on the left-hand wing of the aircraft. Flight research tests were performed for 20 combinations of speed and altitude within a flight envelope that extended to Mach numbers of 0.85 and altitudes of 12,192m (40,000 ft). Propfan blade stress, near-field noise on aircraft surfaces, and cabin noise were recorded. Primary variables were propfan power and tip speed, and the nacelle tilt angle. Extensive low altitude far-field noise tests were made to measure flyover and sideline noise and the lateral attenuation of noise. In coopertion with the FAA, tests were also made of flyover noise for the aircraft at 6100m (20,000 ft) and 10,668m (35,000 ft). A final series of tests were flown to evaluate an advanced cabin wall noise treatment that was produced under a separate program by NASA-Langley Research Center
