The Rhetoric of Silence: John Cage, Exigence and the Art of the Commonplace

Wilcox, Stephen January 2009 (has links)
This thesis approaches the work of American avant-garde composer John Cage from an unconventional perspective by utilizing rhetorical theory to examine the intellectual history informing his collected writings in the text Silence (1961). That historical period encompasses the whole of the commonplace art movement, which sought to have everyday items and experiences supplant art objects. In applying Lloyd F. Bitzer’s theory of the rhetorical situation to the history of the art of the commonplace, a new concept of influence between artists emerges, one where exigences and situations shape popular notions of art. Briefly stated, a recurring exigence appeared throughout this period, bringing with it the necessary parameters for the inclusion of the commonplace within the realm of the art. From William Wordsworth, Walt Whitman, and Ralph Waldo Emerson through to Marcel Duchamp and Andy Warhol, this exigence can be seen constraining the actions of artists towards a fitting, persuasive method. It is in John Cage that one finds this new method. Demonstrated through numerous examples of Cage’s work, this methodology skews the traditional perception of the artist, forgoing the ego, invoking indeterminacy and using structure to emphasize the process of composition itself. This enabled pieces of music and writing that lacked any discernable intention and therefore invited readers to engage the material therein for what it was originally: sounds and words. The result is, at long last, a persuasive and compelling reason to accept commonplace experiences alongside art works and it is evidenced by the Pop movement that would follow shortly thereafter.

Use of biomass model to asses species and productionprofile of marine cage culture in Taiwan

Huang, Wei-yu 14 August 2005 (has links)
Several species of fishes have been used for cage culture in Taiwan, including cobia, brown croaker, red drum, grouper, red seabream, emperor and snapper. Roughly speaking, the main factors determining the choice of the target species are mainly the selling price deleting the production cost. Different species have different biological characteristics that affect the economical performance. Included were specific growth rates, death or survival within cultural period, and efficiency in food conversion, etc.. By employing and modified the so-called Biomass model used in fishery biology (Kings, 1995), this research integrates the above factors into one single spreadsheet for each individual species, allowing for systematic observation of the continuous change in level of production (in terms of biomass). Through the culturing period, degrade in number was gradually offset by the gain in averaged body weights until a maximum value is reached before going downhill. This gives rise to the optimal solution of yield with the respective culturing period thus required. The results for different species were further compared in terms of expected investment and return by the end of the production. Results from this study showed that cobia has more advantage (in terms of biomass, biovalue and return on investment) than others as the prior choice under the current situation. Basic information for this study included the value of natural mortality, length-and-weigh relationship and the growth equation of the target species. The system was programmed under the EXCEL-Spreadsheet system of the Microsoft Inc. In the future other species of fishes may also be tested as possible candidates for cage culture. The program could also expected to serve as an auxiliary tool in education and fishery extension services.

Studies of the Reactions of EtMgOR (R= Et, Me)with Mg(CCR')2 (R'= tBu, SiMe3)

Lin, Chih-Chieh 25 July 2000 (has links)
The reactions of organomagnesium akoxides EtMgOR (R= Me, Et) with dialkynyl magnesium complexes Mg(CoCR¢F) (R¢F= tBu, SiMe3) give a series of the tetranuclear magnesium complexes [Mg4(OR)2Et2(CoCR¢F)4(THF)4] (R= Me, Et; R¢F= tBu, SiMe3). The reactions of diethyl magnesium complexes MgEt2 with alkynes HCoCR (R= tBu, SiMe3) give two different kinds magnesium complexes. One kind is [Mg4(OEt)2-Et2(CoCR)4(THF)4] (R= tBu, SiMe3); another kind is [Mg4O(CoCR)6(THF)4] (R= tBu, SiMe3). Besides, the reaction of diisopropylamide magnesium complex Mg(NiPr2)2 with alkyne HCoCtBu give first example including two different kind bridge ligands trinuclear magnesium complex Mg3(NiPr2)2(CoCtBu)4(THF)2.

study on the devdlopment of net-cage fish-farming in Taiwan

Yang, Bo-ren 26 July 2002 (has links)
There are many approach for The study of marine resources and now in Taiwan is a lot of express , but the damage to net-cage by typhoon is cost much money . The most important study in Taiwan is to use new teconology to update the traditional business and get advanture in international.

Field, generalised theory and finite element analysis of a six-phase squirrel cage induction machine.

Appiah, Edward Kofi. January 2013 (has links)
M. Tech. Electrical Engineering. / Investigates the mathematical modelling, analysis and simulation of a six-phase squirrel cage induction machine. This dissertation is the report of the analysis and simulation of this machine through three methods, namely: The direct-quadrature axis (dqxy0102) based on generalised theory of electric machines, which enabled the machine to be mathematically modelled in the arbitrary reference frame; the classical magnetic field distribution analysis; and the finite element method (fem). The resulting models of the analysis of the six-phase squirrel cage induction machine are implemented by simulation using appropriate software. The simulations generate unique results of the steady-state and the dynamic performance characterising the performance of the six-phase squirrel cage induction machine. Tests are conducted on a 1.5 kW experimental machine whereby the performance characteristics of the theoretical analysis and simulations are validated with the experimental results. The results of the three are compared among themselves, and also with the experimental results to appraise the suitability of each method for the modelling and analysis of the hpo machine.Even though six-phase machine is considered in this study it is believed that the methods as applied in this work are generally applicable to hpo squirrel cage induction machine of any number of phases.

Nutrient dynamics and production performance of Shaver White laying hens housed in either enriched or conventional cage systems over an entire production cycle

Neijat, Mohamed 30 August 2011 (has links)
The current data provide estimates of the flow of nitrogen (N), calcium (Ca) and phosphorus (P) in Shaver White layers housed under conventional cage (CC) and enriched cage (EC) systems from 19 to 63 wks of age. The experiment was conducted at the University of Manitoba poultry unit. Both feed disappearance (P < 0.01) (92.5 vs. 95.0 ± 0.6 g/hen/d, DM basis) and manure output (P < 0.01) (79.8 vs. 91.3 ± 1.2 g/hen/d, fresh basis and 27.0 vs. 28.1 ± 0.2 g/hen/d, DM basis) were lower in hens housed in EC compared to CC. Manure DM was 34.1 and 31.0 ± 0.3% for EC and CC, respectively. Feed conversion ratio; body weight; and egg production, weight and mass were not significantly different between the two systems. Although there was no difference in the overall manure N (EC: 1.94 vs. CC: 1.96 ± 0.02 g/hen/d, respectively), N balance was greater (P < 0.05) for the CC compared to EC system (85.0 vs. 30.2 ± 13.6 mg/hen/d, respectively). Lower (P < 0.01) Ca and P excretions were observed in EC (Ca: 2.11 vs. 2.29 ± 0.04 and P: 0.619 vs. 0.643 ± 0.005 g/hen/d) compared to CC. Overall egg N output was similar between the systems. Although lower Ca deposition (P < 0.0001) (2.07 vs. 2.13 ± 0.01 g/hen/d) and output (P < 0.05) (38.3 vs. 38.8 ± 0.15 mg/g egg) were noted in eggs from EC compared to CC, shell quality measurements were not different between the two systems. In addition, Ca outputs in eggs expressed as a proportion of Ca intake in both systems were similar (56.5 vs. 56.6 ± 0.51). Although overall mean P retention (-7.22 vs. -7.45 ± 0.71% P intake) was not different between the two groups of hens, Ca retention was higher (P < 0.05) in EC than CC hens (-1.37 vs. -4.76 ± 0.89% Ca intake, respectively). In addition to providing environmental enrichment and maintaining the production performance to the levels of those achieved by CC systems, EC may also help in reducing Ca and P excretions and improving their efficiency of utilization.
