Narrative at Risk: Accident and Teleology in American Culture, 1963-2013

Accident in fiction is always inevitable. When a character in a novel suffers a car accident, for example, the accident is the effect of the author\u27s intentions, and therefore it is not accidental. The words and images that constitute the meanings and events of the text do not change. The accidents in the narrative always happen the same way, reading after rereading. Drawing from this observation, the question that Narrative at Risk attempts to answer is, in its simplest iteration: how can narrative accurately represent accident when its textual representation is not subject to the effects of accident? I ask this of a number of American cultural objects that were produced over the last fifty years, from the assassination of President John F. Kennedy to the present. Narrative at Risk interrogates representations of accident primarily in novels and films--but also in television, roleplaying games, comic strips, and videogames--in order to examine how contemporary American culture ascribes meaning to the accidental. I read a wide array of accidents--from mechanical failures to failed suicides, depictions of biological evolution to games of chance--as providing a broad but nonetheless coherent understanding of how American society has conceived of accident in relation to individuals, communities, and the species as a whole. Narrative at Risk, in treating media such as film, television, and videogames alongside literature, broadens our understanding of how accident developed as a danger over the past fifty years, as well as how various media influenced and shaped one another through borrowed reading practices. In the introduction, I focus on the crystallization of the mass media that brought traumatic events into American homes again and again, specifically, the moment of President John F. Kennedy\u27s assassination and the epistemological and ontological crises this event and its media coverage initiated. The first chapter reads the role of this mediation and the crises of the 1960s as they jointly inform representations of accidental mechanical failure. Through readings of four texts, I theorize a politics of accident, taking as my initial subject what Ronald Reagan called his most formative moment: his role as a train accident victim in King\u27s Row: 1941), and his discussion of this role in his 1965 memoir Where\u27s the Rest of Me? I delineate how Reagan\u27s obsession with narrating accident later shaped a politics of the accident in texts such as David Cronenberg\u27s film Crash: 1996), Don DeLillo\u27s novel White Noise: 1985), Colson Whitehead\u27s novel The Intuitionist: 1999), and Rockstar Game\u27s Grand Theft Auto: San Andreas: 2004). The subsequent chapter shifts from the first\u27s broad historical range to texts composed and published at the end of the Cold War: Paul Auster\u27s novel Leviathan: 1992); Jeffrey Eugenides\u27s novel The Virgin Suicides: 1993); and Musings of a Cigarette Smoking Man : 1996) an episode of the television show The X-Files: 1993-2002). I read the failure of suicide attempts in these texts as accidents that express the limits of intentionality, which bring to the fore the nation\u27s inability to conceive of a future beyond the ideological bounds of the conflict with the Soviet Union that provided meaning during the Cold War. The third chapter recontextualizes the final years of the Cold War. Here I read Richard Kenney\u27s poem, A Colloquy of Ancient Men from his collection, The Invention of the Zero: 1993), alongside two novels: Michael Crichton\u27s Jurassic Park: 1990) and Richard Powers\u27s The Gold Bug Variations: 1991). Rather than depicting the futurelessness of the United States, these texts look to deep history on the scale of evolutionary time. They depict evolution as a series of random, accidental changes that take place in the history of a species\u27 development; in doing so, they together trace the Cold War fear of thermonuclear annihilation shifting to an anxiety of genetic manipulation. The fourth chapter turns to the 1970s to investigate the early years of the culture wars. I begin by reading how chance disrupts the narrative of Kathy Acker\u27s novel Blood and Guts in High School: 1984), then consider the religious right\u27s hyperbolic condemnation of chance in TSR\u27s roleplaying game Dungeons & Dragons: 1974). I then scrutinize games of chance in three other texts: Michael Cimino\u27s film The Deer Hunter: 1978); Thomas Pynchon\u27s novel Gravity\u27s Rainbow: 1973); and Sam Lipsyte\u27s short story The Dungeon Master : 2010). These three cases demonstrate how chance undermines the paranoid fantasy that there are external forces authoring the world. Finally, Narrative at Risk concludes with an exploration of accident in the present through a discussion of two television shows--Breaking Bad: 2008-2013) and The Americans: 2013-)--and Steve Erickson\u27s 2012 novel These Dreams of You. Imagining accidents as the fault of the government, these texts collectively suggest American culture\u27s continued reliance upon teleological thinking and conspiracy theory

Aggregates relaxation in a jamming colloidal suspension after shear cessation

The reversible aggregates formation in a shear thickening, concentrated colloidal suspension is investigated through speckle visibility spectroscopy, a dynamic light scattering technique recently introduced [P.K. Dixon and D.J. Durian, Phys. Rev. Lett. 90, 184302 (2003)]. Formation of particles aggregates is observed in the jamming regime, and their relaxation after shear cessation is monitored as a function of the applied shear stress. The aggregates relaxation time increases when a larger stress is applied. Several phenomena have been proposed to interpret this behavior: an increase of the aggregates size and volume fraction, or a closer packing of the particles in the aggregates.Comment: 7 pages, 7 figures; added figures included in the pdf versio

Direct observation of charge inversion by multivalent ions as a universal electrostatic phenomenon

We have directly observed reversal of the polarity of charged surfaces in water upon the addition of tri- and quadrivalent ions using atomic force microscopy. The bulk concentration of multivalent ions at which charge inversion reversibly occurs depends only very weakly on the chemical composition, surface structure, size and lipophilicity of the ions, but is dominated by their valence. These results support the theoretical proposal that spatial correlations between ions are the driving mechanism behind charge inversion.Comment: submitted to PRL, 26-04-2004 Changed the presentation of the theory at the end of the paper.

Direct Wolf summation of a polarizable force field for silica

We extend the Wolf direct, pairwise r^(-1) summation method with spherical truncation to dipolar interactions in silica. The Tangney-Scandolo interatomic force field for silica takes regard of polarizable oxygen atoms whose dipole moments are determined by iteration to a self-consistent solution. With Wolf summation, the computational effort scales linearly in the system size and can easily be distributed among many processors, thus making large-scale simulations of dipoles possible. The details of the implementation are explained. The approach is validated by estimations of the error term and simulations of microstructural and thermodynamic properties of silica.Comment: See http://link.aip.org/link/?JCP/132/194109 - 8 pages, 6 figures.

Water adsorption on amorphous silica surfaces: A Car-Parrinello simulation study

A combination of classical molecular dynamics (MD) and ab initio Car-Parrinello molecular dynamics (CPMD) simulations is used to investigate the adsorption of water on a free amorphous silica surface. From the classical MD SiO_2 configurations with a free surface are generated which are then used as starting configurations for the CPMD.We study the reaction of a water molecule with a two-membered ring at the temperature T=300K. We show that the result of this reaction is the formation of two silanol groups on the surface. The activation energy of the reaction is estimated and it is shown that the reaction is exothermic.Comment: 12 pages, 6 figures, to be published in J. Phys.: Condens. Matte

Silica nanowires templated by amyloid-like fibrils

Many peptides self-assemble to form amyloid fibrils. We previously explored the sequence propensity to form amyloid using variants of a designed peptide with sequence KFFEAAAKKFFE. These variant peptides form highly stable amyloid fibrils with varied lateral assembly and are ideal to template further assembly of non-proteinaceous material. Herein, we show that the fibrils formed by peptide variants can be coated with a layer of silica to produce silica nanowires using tetraethyl-orthosilicate. The resulting nanowires were characterized using electron microscopy (TEM), X-ray fiber diffraction, FTIR and cross-section EM to reveal a nanostructure with peptidic core. Lysine residues play a role in templating the formation of silica on the fibril surface and, using this library of peptides, we have explored the contributions of lysine as well as arginine to silica templating, and find that sequence plays an important role in determining the physical nature and structure of the resulting nanowires

Molecular dynamics simulation of nanocolloidal amorphous silica particles: Part II

Explicit molecular dynamics simulations were applied to a pair of amorphous silica nanoparticles of diameter 3.2 nm immersed in a background electrolyte. Mean forces acting between the pair of silica nanoparticles were extracted at four different background electrolyte concentrations. Dependence of the inter-particle potential of mean force on the separation and the silicon to sodium ratio, as well as on the background electrolyte concentration, are demonstrated. The pH was indirectly accounted for via the ratio of silicon to sodium used in the simulations. The nature of the interaction of the counter-ions with charged silica surface sites (deprotonated silanols) was also investigated. The effect of the sodium double layer on the water ordering was investigated for three Si:Na+ ratios. The number of water molecules trapped inside the nanoparticles was investigated as the Si:Na+ ratio was varied. Differences in this number between the two nanoparticles in the simulations are attributed to differences in the calculated electric dipole moment. The implications of the form of the potentials for aggregation are also discussed.Comment: v1. 33 pages, 7 figures (screen-quality PDF), submitted to J. Chem. Phys v2. 15 pages, 4 tables, 6 figures.

Temperature control in molecular dynamic simulations of non-equilibrium processes

Thermostats are often used in various condensed matter problems, e.g. when a biological molecule undergoes a transformation in a solution, a crystal surface is irradiated with energetic particles, a crack propagates in a solid upon applied stress, two surfaces slide with respect to each other, an excited local phonon dissipates its energy into a crystal bulk, and so on. In all of these problems, as well as in many others, there is an energy transfer between different local parts of the entire system kept at a constant temperature. Very often, when modelling such processes using molecular dynamics simulations, thermostatting is done using strictly equilibrium approaches serving to describe the NV T ensemble. In this paper we critically discuss the applicability of such approaches to non-equilibrium problems, including those mentioned above, and stress that the correct temperature control can only be achieved if the method is based on the generalized Langevin equation (GLE). Specifically, we emphasize that a meaningful compromise between computational efficiency and a physically appropriate implementation of the NV T thermostat can be achieved, at least for solid state and surface problems, if the so-called stochastic boundary conditions (SBC), recently derived from the GLE (Kantorovich and Rompotis 2008 Phys. Rev. B 78 094305), are used. For SBC, the Langevin thermostat is only applied to the outer part of the simulated fragment of the entire system which borders the surrounding environment (not considered explicitly) serving as a heat bath. This point is illustrated by comparing the performance of the SBC and some of the equilibrium thermostats in two problems: (i) irradiation of the Si(001) surface with an energetic CaF2 molecule using an ab initio density functional theory based method, and (ii) the tribology of two amorphous SiO2 surfaces coated with self-assembled monolayers of methyl-terminated hydrocarbon alkoxylsilane molecules using a classical atomistic force field. We discuss the differences in behaviour of these systems due to applied thermostatting, and show that in some cases a qualitatively different physical behaviour of the simulated system can be obtained if an equilibrium thermostat is used

A provisional database for the silicon content of foods in the United Kingdom

Si may play an important role in bone formation and connective tissue metabolism. Although biological interest in this element has recently increased, limited literature exists on the Si content of foods. To further our knowledge and understanding of the relationship between dietary Si and human health, a reliable food composition database, relevant for the UK population, is required. A total of 207 foods and beverages, commonly consumed in the UK, were analysed for Si content. Composite samples were analysed using inductively coupled plasma&ndash;optical emission spectrometry following microwave-assisted digestion with nitric acid and H2O2. The highest concentrations of Si were found in cereals and cereal products, especially less refined cereals and oat-based products. Fruit and vegetables were highly variable sources of Si with substantial amounts present in Kenyan beans, French beans, runner beans, spinach, dried fruit, bananas and red lentils, but undetectable amounts in tomatoes, oranges and onions. Of the beverages, beer, a macerated whole-grain cereal product, contained the greatest level of Si, whilst drinking water was a variable source with some mineral waters relatively high in Si. The present study provides a provisional database for the Si content of UK foods, which will allow the estimation of dietary intakes of Si in the UK population and investigation into the role of dietary Si in human health.<br /
