Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Frontiers of UV resonant raman spectroscopy by using synchrotron radiation: The case of aqueous solvation of model peptides
No full textUV Resonance Raman (UVRR) scattering offers several advantages with respect to spontaneous Raman one, such as the significant increment of the detection limit and the selectivity needed to incisively monitor specific chromospheres within the sample. Here we present a synchrotron-based Resonance Raman instrument that exploits the wide and continuously tunable UV emission provided by the synchrotron source. As an example, we discuss the solvation dynamics of two model peptides, N-acetyl-leucine-methylamide (NALMA) and N-acetyl-glycine-methylamide (NAGMA), by putting in evidence on the advantages of the use of SR-based UVRR. The experimental results evidence that the fine tuning of the excitation wavelength allows to choose the best working conditions that ensure to reliably detect the spectral changes of the amide signals, as function of concentration and temperature of peptide. The analysis of the spectra provides new insights on the hydrogen-bond interactions at the peptides backbone
