Relating Noncommutative SO(2,3) Gravity to the Lorentz-Violating Standard-Model Extension

We consider a model of noncommutative gravity that is based on a spacetime with broken local SO(2,3) symmetry. We show that the torsion-free version of this model is contained within the framework of the Lorentz-violating Standard-Model Extension. We analyze in detail the relation between the torsion-free, quadratic limits of the broken SO(2,3) model and the Standard-Model Extension. As part of the analysis,we construct the relevant geometric quantities to quadratic order in the metric perturbation around a flat background.Comment: 10 pages, accepted in Symmetr

A RUPTURED VISION: THE SYMBIOTIC RELATIONSHIP BETWEEN LITERARY MODERNISM AND CINEMA

ABSTRACT The study of Modernism has often been divided by a seemingly unbridgeable gap between what has been deemed \u27high\u27 art, esoteric works intended for the privileged few, and \u27low\u27 culture-works intended for the groveling masses. In the first category are traditional art forms such as painting, sculpture, and literature. The lower art forms include mass-produced works that are accessible by design. Until the latter portion of the previous century the cinema, arguably the most important artistic medium of the twentieth century has been assessed as merely disposable popular culture, an \u27other\u27 to the world of traditional \u27high\u27 art. This is no longer the case. Cinema studies have emerged as an accepted discipline across the academy. However, many scholars have overlooked the direct correlation between literary modernism and the maturation of the cinema. It is my intent to prove that literary modernism and the cinema are bound by a common language as well as a common desire to make artistic meaning in a ruptured world. Therefore, I find it imperative to study not only the influence of literature on the cinema, but also the enormous contribution cinematic tropes have made on the development of many of the most renowned works of literary modernism

An Introduction to Open Access

Open Access (OA) to literature, means its free availability on the public internet, permitting any users to read, download, copy, distribute, print, search, or link to the full texts of these articles, crawl them for indexing, pass them as data to software, or use them for any other lawful purpose, without financial, legal, or technical barriers other than those inseparable from gaining access to the Internet itself. The only condition on reproduction and distribution, and the only role for copyright in this domain, is to give authors control over the integrity of their work and the right to be properly acknowledged and cited. This slightly revised (by editors of IS) version of the popular introductory paper on Open Access by Charles W. Bailey, Jr defines Open Access and traces out the OA movement from Budapest Open Access Initiative to present. It describes the many degrees and kinds of OA, and different strategies, practices, and laws related to it

Consumption, Time Preference, and the Life Cycle

This paper presents two life-cycle models of consumption implementing novel assumptions about time preference and subjective time. The goal of this paper is to investigate implications of the existence of subjective time to consumption decisions over the life cycle. The first model is a model of \u27systematic impatience\u27 and implements the assumption of increasing subjective time by specifying a time dependent rate of time preference upon which the rational consumers in this model maximize lifetime utility. The second model investigates consumer behavior in subjective time, or the subjective sense of the actual passage of time. Consumers in this model maximize lifetime utility in subjective time. The optimal subjective consumption and saving functions are then mapped into real time. Both models are then compared to empirical findings on consumption theory

Molecular Force Fields of Ethylene, Allene, Formaldehyde, Ketene, and Diazomethane

Infrared and Raman spectra furnish one of the most powerful methods for studying the internal forces which act in molecules. The vibrational frequencies which are obtained from a study of the spectra are functions of the geometry and masses, which determine the kinetic energy of the system, and of the forces acting in the molecule, which determine the potential energy of the system. Therefore, if the geometry of a molecule is known, the vibrational frequencies of the molecule can be used to ob­tain information concerning the forces acting during the motions

Stalk borer phenology, damage syndrome, and yield loss potential in field corn

Adult phenology, relative abundance, and reproductive status of feral stalk borer moths, Papaipema nebris (Gn.), were investigated from 1980 to 1983, using collections from blacklight traps. Males constituted 89.2% of trap collections versus 10.8% female moths. In all four years, the first moth was collected between 10 and 21 August and 50% flight occurred between 8 and 14 September. Multiple matings by female moths were common, with the mean number of spermatophores being 2.0, but total numbers ranging from 0 to 7 spermatophores per female. Although the dates of flights in this study agreed with Illinois dates, the thermal-unit model proposed in previous literature failed to predict satisfactorily adult phenology in Iowa, suggesting that factors other than CDD accumulations influence dates of adult emergence and subsequent flights;Additionally, effects of stalk borer damage on 2- to 4-leaf-stage field corn was studied to characterize the plant damage syndrome and subsequent yield losses associated with larval infestations. Damage was categorized as uninfested, leaf-feeding only, or dead-heart (whorl death). Yields of stalk, grain, cob, and total dry weights were monitored from both damaged plants and plants growing adjacent to damaged plants. Yields of plants sustaining leaf-feeding damage alone were not significantly different from yields of uninfested plants. Dead-heart damaged plants, however, produced yields significantly reduced from yields of all other plants except for the parameter of stalk dry weight. Lack of reproductive synchrony with healthy plants seemed to cause the reduced yields produced by plants with dead-heart damage. In all probability, this loss of synchrony resulted in greatly diminished pollination and increased numbers of barren stalks for plants sustaining injury. In the absence of mortality, yield compensation by healthy plants growing near damaged plants was not observed. Damage from larval infestations of corn plants growing adjacent to brome grass terraces was most severe in the first row of corn bordering the terrace and gradually decreased in severity with distance away from the terrace

Variation In The Shell Morphology And Growth Rate Of Lampsilis Radiata, A Freshwater Mussel

I measured a correlation between the habitat of a freshwater mussel, Lampsilis radiata siliquoidea (Barnes 1823), and its shell morphology and growth rate. I then tried to determine the source of morphological and growth rate variation (environmental or genetic), and whether or not the phenotype/habitat correlation was due to differential adaptation.;Morphometric and annual ring analysis of mussels from Inner Long Point Bay, Lake Erie indicated that L. radiata from more exposed, sandier areas of the bay were faster growing and had thicker shells than those from less exposed, muddy areas. Variation among exposure areas in allozyme phenotypes of two gene loci (PGM and PGI) showed little evidence of genetic divergence. Statistically significant heterogeneity among exposure areas in PGM genotypes was small relative to that between mussel populations in Balsam Lake (in the Trent-Severn watershed) and the lower Great Lakes. Heritabilities of glochidia shell dimensions were low ({dollar}\u3c{dollar}20%), providing little evidence of past or present disruptive selection of shell dimensions. Substrate preference was displayed by the mussels in experimental ponds. L. radiata preferred a finer, more heterogeneous substrate over a coarse sand, and larger mussels showed a stronger substrate preference than smaller individuals. Such habitat preference could influence the breeding structure of the population near the borders of habitat areas.;A laboratory experiment using L. radiata from Inner Long Point Bay showed that the optimal shell morphology for burrowing depended on the substrate the mussel was placed in. Less obese, thinner-shelled mussels were better burrowers in sand; the converse was true in mud. The pattern of optimal burrowing morphologies found in the laboratory experiment did not accurately predict morphological variation in the natural population. This could be because of (i) a poor fitness surrogate (burrowing), (ii) lack of important environmental variation in the experiment (e.g. turbulence), or (iii) a non-adaptive pattern of morphological variation in the natural population
