A Computer Music Retrospective

A composer who has worked in the field of computer music for the last 25 years reflects on how technological developments during that time have affected his work in computer music, instrumental music and hybrid combinations of the two. The compositional trajectories traced here often run parallel to opportunities afforded by the evolution of computer technology suitable for the generation of digital audio.

HIGH-FIDELITY MUSIC CODING AT 4 BITS.

A very high-quality sub-band ADPCM music coding scheme which compresses high-fidelity music signals, bandlimited to 15kHz, to an equivalent PCM representation of only 4 bits per sample, is described. By processing music sampled at 32 kHz, this coder exhibits a total bit rate of only 128kbit/s and is consequently applicable to the ISDN. Subjective tests conducted with this coder have shown that music recovered from the compression scheme is essentially indistinguishable from the original material. The results obtained are of major importance, not only for ISDN and broadcasting, but also for other digital audio technology such as compact disc (CD) and digital audio tape.

Development of a Temperature-Recording Vaginal Ring for Monitoring User Adherence

Background: Vaginal ring devices are being actively developed for controlled delivery of HIV microbicides and as multi-purpose prevention technology (MPT) products combining hormonal contraception with prevention of HIV and other sexually transmitted diseases. Presently, there is no reliable method for monitoring user adherence in HIV vaginal ring trials; previous acceptability studies have included some type of participant self-reporting mechanism, which have often been unreliable. More objective, quantitative and accurate methods for assessing adherence are needed.
Methods: A silicone elastomer vaginal ring containing an encapsulated miniature temperature recording device has been developed that can capture and store real-time temperature data during the period of designated use. Devices were tested in both simulated vaginal environments and following vaginal placement in cynomolgus macaques. Various use protocols and data sampling rates were tested to simulate typical patient usage scenarios. Results: The temperature logging devices accurately recorded vaginal temperature in macaques, clearly showing the regular diurnal temperature cycle. When environmental temperature and vaginal temperature was significantly different, the device was able to accurately pinpoint the insertion and removal times. Based on the data collected it was possible to infer removal periods as short as 5 min when the external environmental temperature was 25 °C. Accuracy increased with data sampling rate. Conclusions: This work provides proof-of-concept for monitoring adherence using a vaginal ring device containing an encapsulated temperature logger. The addition of one or more active agents into the ring body is not anticipated to affect the temperature monitoring function. A clinical study to compare self- reported user adherence data with that obtained by the device would be highly informative.

Engendering Hope: A person-centred reflection on technology and gender

This paper examines instances of recent musical and artistic works and asks to what extent it makes sense to regard certain practices and technologies as gendered. It looks at a number of strategies for making, suggesting that male gender stereotypes are as prevalent and unhelpful (to practitioners) as female ones. It looks at aspects of the working environments of practitioners to determine whether changes in such conditions might alleviate the gender mismatch in enrolment in higher education courses featuring ubiquitous technologies. The paper identifies historical precedents for technology gendering in which readings of such gendering have shifted radically, suggesting they offer scope for optimism in our longer-term reading of the gendered-ness of current practices. The paper also touches on the extent to which a ‘research’ ethos––the foregrounding of the essential human attributes of inquisitiveness and empathy––may contribute to our capacity to tell better, less binary stories of otherness in all its forms.

You get what you pay for : independent music and Canadian public policy

The aim of this MA thesis is to demonstrate how corporate concentration within the global music industry specifically affects the Canadian music industry's ability to compete for its own national audience as well as audiences worldwide. Federal public policies, regulatory regimes and subsidies are considered within the context of the structure of the global marketplace which is, in effect, an oligopoly controlled by four major corporations. Through an extensive literature review of political economy theory, Canadian public policies and music studies, as well as personal interviews conducted with Canadian musicians, entrepreneurs and public servants, I will situate my research within the body of political economy theory; present a detailed report of the structure of the global music industry; address the key players within the industry; describe the relationship between the major corporations and the independent companies operating in the industry; discuss how new technologies affect said relationships; consider the effectiveness of Canadian public policies in safeguarding the national music industry; and recommend steps that can be taken to remedy the shortcomings of Federal policies and regulatory regimes.

His invitees are Lisa Eckenwiler, Associate Professor of Philosophy in the Department of Philosophy and in the Department of Health Administration and Policy at George Mason University; and Chris Macdonald, Associate Professor of Philosophy at Saint Mary’s University in Halifax. You will also hear General International, an experimental/avant-garde music band that was formed only a few months ago.

Music, Padlocks and the Commons

Depuis l’avènement des formats de compression numérique et des services d’échange point à point (Peer-to-Peer) comme Napster, l’industrie du disque est en émoi. Plus fondamentalement, il y a lieu de se questionner sur ce qui apparaît comme une crise d’efficacité du droit d’auteur. Si les copistes semblent avoir pris de court de puissants intérêts, les contre-mesures ne sauraient tarder à venir. L’apparition de protections techniques ­ Trusted Systems ­ présage une ère de contrôle total par les titulaires de droits. L’«hyper efficacité» bouleversera le rapport à l’œuvre, entraînant du même souffle un déséquilibre dans les dimensions privée et publique du droit d’auteur.

Spectacle and the one-man band : technology, performing bodies, and imaginary spaces

L’étiquette « homme-orchestre » est apposée à une grande variété de musiciens qui se distinguent en jouant seuls une performance qui est normalement interprétée par plusieurs personnes. La diversité qu’a pu prendre au cours du temps cette forme n’est pas prise en compte par la culture populaire qui propose une image relativement constante de cette figure tel que vue dans les films Mary Poppins (1964) de Walt Disney et One-man Band (2005) de Pixar. Il s’agit d’un seul performeur vêtu d’un costume coloré avec une grosse caisse sur le dos, des cymbales entre les jambes, une guitare ou un autre instrument à cordes dans les mains et un petit instrument à vent fixé assez près de sa bouche pour lui permettre d’alterner le chant et le jeu instrumental. Cette thèse propose une analyse de l’homme-orchestre qui va au-delà de sa simple production musicale en situant le phénomène comme un genre spectaculaire qui transmet un contenu symbolique à travers une relation tripartite entre performance divertissante, spectateur et image. Le contenu symbolique est lié aux idées caractéristiques du Siècle des lumières tels que la liberté, l’individu et une relation avec la technologie. Il est aussi incarné simultanément par les performeurs et par la représentation de l’homme-orchestre dans l’imaginaire collectif. En même temps, chaque performance sert à réaffirmer l’image de l’homme-orchestre, une image qui par répétitions est devenue un lieu commun de la culture, existant au-delà d’un seul performeur ou d’une seule performance. L’aspect visuel de l’homme-orchestre joue un rôle important dans ce processus par une utilisation inattendue du corps, une relation causale entre corps, technologie et production musicale ainsi que par l’utilisation de vêtements colorés et d’accessoires non musicaux tels des marionnettes, des feux d’artifice ou des animaux vivants. Ces éléments spectaculaires divertissent les spectateurs, ce qui se traduit, entre autres, par un gain financier pour le performeur. Le divertissement a une fonction phatique qui facilite la communication du contenu symbolique.

Methylene Blue Doped Polymers: efficient Media for Optical Recording

Polymer materials find application in optical storage technology, namely in the development of high information density and fast access type memories. A new polymer blend of methylene blue sensitized polyvinyl alcohol (PVA) and polyacrylic acid (PAA) in methanol is prepared and characterized and its comparison with methylene blue sensitized PVA in methanol and complexed methylene blue sensitized polyvinyl chloride (CMBPVC) is presented. The optical absorption spectra of the thin films of these polymers showed a strong and broad absorption region at 670-650 nm, matching the wavelength of the laser used. A very slow recovery of the dye on irradiation was observed when a 7:3 blend of polyvinyl alcohol/polyacrylic acid at a pHof 3.8 and a sensitizer concentration of 4.67 10 5 g/ml were used. A diffraction efficiency of up to 20% was observed for the MBPVA/alcohol system and an energetic sensitivity of 2000 mJ/cm2 was obtained in the photosensitive films with a spatial frequency of 588 lines/mm.
