    An Impossible Utopia: People’s Art and the Cultural Revolution

    Full text link
    The Great Proletarian Cultural Revolution period of the People’s Republic of China (1966-1976) was crucial in the creation of modern-day China. The material culture of that period mirrors the turbulent political activity of students and the directives of the Communist Party’s central leadership during the height of the Mao Zedong personality cult. The commercial manufacture of posters, often the sole decoration available for the public and private spheres, offers strong examples of the design style of this time. The posters are not only indicative of the propagandistic fervor of production, but the aesthetic changes initiated in the visual and performing arts during the period as the state consciously manipulated style in an effort to create a “people’s” art and envision a Marxist utopia. This paper suggests that a comprehension of folk arts and popular culture is essential for understanding the visual language of this specific geographic and political space. A new perspective on the reconciliation of reality and ideology during the Cultural Revolution is gained through an analysis of popular form and content, and reveals not only the basis of a modern mass culture, but the unprecedented unification of high and low art forms

    MS-172: Paxton Family Papers

    Full text link
    This set of papers presents a variety of notes and correspondences between members of the family and friends. The bulk of the letters date 1895 and come from Elizabeth D. Paxton and Margaretta Paxton to their mother, Caroline Sophia Denny Paxton, while touring Europe. There are letters from James Dunlop and Harmar Denny to their mother, as well as condolence letters for Mr. and Mrs. William M. Paxton upon the death of Harmar Denny in 1896. This collection may prove useful for a researcher conducting a study of the Paxton family, or one interested in the travels of Americans in Europe at the end of the 19th century. This collection does not contain information relevant to William Miller Paxton’s time at Gettysburg or his career.

    Field and Factory: Chinese Revolutionary Posters

    Full text link
    The images on display for Field and Factory, political propaganda used by the Communist Party of China during the 1950s, 60s, and 70s, construct a fictitious world. In perceiving these kinds of illustrations, the audience is asked either to visualize the society in its ideal form or unify in opposition to a national enemy. In the first half of the twentieth century, before the possibilities of the television advertisement were fully realized, posters were one of the most popular forms of propaganda: cheap to produce in mass quantities and simple enough to hang in any public building. The art form’s bold aesthetics encouraged mass mobilization during intense periods of war and political upheaval. The posters in this exhibition represent a myriad of political agendas promoted by the Communist Party of China during its early development after the formation of the People’s Republic of China in 1949. Posters were viewed by all citizens in both the private and public sphere; by abolishing other varieties of personal expression, the Communist Party sought control of its population. Whether the posters were sought after as decoration in the home or transmitters of political policy, they became, by default, the most popular form of imagery in China during that time. By glorifying certain aspects of Chinese life, these images help to shape the elements of national identity for a newly founded modern China.

    Hydrogen-fueled engine

    Get PDF
    A hydrogen-oxygen fueled internal combustion engine is described, which utilizes an inert gas, such as argon, as a working fluid to increase the efficiency of the engine, eliminate pollution, and facilitate operation of a closed cycle energy system. In a system where sunlight or other intermittent energy source is available to separate hydrogen and oxygen from water, the oxygen and inert gas are taken into a diesel engine into which hydrogen is injected and ignited. The exhaust is cooled so that it contains only water and the inert gas. The inert gas in the exhaust is returned to the engine for use with fresh oxygen, while the water in the exhaust is returned to the intermittent energy source for reconversion to hydrogen and oxygen

    Splanchnic metabolism of nutrients and hormones in steers fed alfalfa under conditions of increased absorption of ammonia and L-arginine supply across the portal-drained viscera

    Effects of increased ammonia and/or arginine absorption on net splanchnic (portal-drained viscera [PDV] plus liver) metabolism of nonnitrogenous nutrients and hormones in cattle were examined. Six Hereford × Angus steers (501 ± 1 kg BW) prepared with vascular catheters for measurements of net flux across the splanchnic bed were fed a 75% alfalfa:25% (as-fed basis) corn and soybean meal diet (0.523 MJ of ME/[kg BW0.75.d]) every 2 h without (27.0 g of N/kg of DM) and with 20 g of urea/kg of DM (35.7 g of N/kg of DM) in a split-plot design. Net flux measurements were made immediately before and after a 72-h mesenteric vein infusion of L-arginine (15 mmol/h). There were no treatment effects onPDVor hepaticO2 consumption. Dietary urea had no effect on splanchnic metabolism of glucose or L-lactate, but arginine infusion decreased net hepatic removal of L-lactate when urea was fed (P < 0.01). Net PDV appearance of n-butyrate was increased by arginine infusion (P < 0.07), and both dietary urea (P < 0.09) and arginine infusion (P < 0.05) increased net hepatic removal of n-butyrate. Dietary urea also increased total splanchnic acetate output (P < 0.06), tended to increase arterial glucagon concentration (P < 0.11), and decreased arterial ST concentration (P < 0.03). Arginine infusion increased arterial concentration (P < 0.07) and net PDV release (P < 0.10) and tended to increase hepatic removal (P < 0.11) of insulin, as well as arterial concentration (P < 0.01) and total splanchnic output (P < 0.01) of glucagon. Despite changes in splanchnic N metabolism, increased ammonia and arginine absorption had little measurable effect on splanchnic metabolism of glucose and other nonnitrogenous components of splanchnic energy metabolism

    A frequency weighting for the evaluation of steering wheel rotational vibration

    Get PDF
    The human perception of rotational hand-arm vibration has been investigated by means of a test rig consisting of a rigid frame, an electrodynamic shaker unit, a rigid steering wheel, a shaft assembly, bearings and an automobile seat. Fifteen subjects were tested while seated in a driving posture. Four equal sensation tests and one annoyance threshold test were performed using sinusoidal excitation at 18 frequencies in the range from 3 to 315 Hz. In order to guarantee the generality of the equal sensation data the four tests were defined to permit checks of the possible influence of three factors: reference signal amplitude, psychophysical test procedure and temporary threshold shift (TTSv) caused by the test exposure. All equal sens ation tests used a reference sinusoid of 63 Hz at either 1.0 or 1.5 m/s2 r.m.s. in amplitude. The four equal sensation curves were similar in shape and suggested a decrease in human sensitivity to hand-arm rotational vibration with increasing frequency. The slopes of the equal sensation curves changed at transition points of approximately 6.3 and 63 Hz. A frequency weighting, called Ws, was developed for the purpose of evaluating steering wheel rotational vibration. The proposed Ws has a slope of 0 dB per octave over the frequency range from 3 to 6.3 Hz, a slope of -6 dB per octave from 6.3 to 50 Hz, a slope of 0 dB per octave from 50 to 160 Hz and a slope of -10 dB per octave from 160 to 315 Hz. Ws provides a possible alternative to the existing Wh frequency weighting defined in International Standards Organisation 5349-1 (2001) and British Standards Institution 6842 (1987)
