“Exploring the Acoustic Environment of the Montreal Metro by Doing the ‘Dou-Dou-Dou’”
No full textThe ‘dou-dou-dou’ is the signal heard as train doors on the Montreal Metro close. It was developed by the STM (Société de transport de Montréal) in 2010 as a way to prevent service delays as well as promote safety within the subway environment (namely to prevent commuters getting stuck between doors and to stop fellow passengers pushing each other). Although only a relatively small sequence in the overall acoustic environment of the Metro, the three tones of the ‘dou-dou-dou’ are important in creating a particular type of social space. This article explores the development of this unique part of the acoustic ecology of the Montreal metro system, comparing the STM’s publicity material about the development of the signal with key musical and cultural studies frameworks relating to power and affect. The focus is on the ‘dou-dou-dou’ as a method of sonic management within the metro environment, exploring the flows of power between commuters and officials within the space. In addition to being a pragmatic ‘audio signal’ to direct commuter traffic, we propose that the ‘dou-dou-dou’, with its specific composition and instrumentation, can be understood as more than just a musical marker of place in the broader historical and cultural audio environment of the metro

No full textL'adattazione di Bondì Testario dei Li Livres dou Tresor di Brunetto LatiniPietro Beltrami, gran conoscitore dei Li Livres dou Tresor di Brunetto Latini, ha invitato gli studiosi ad orientare la loro ricerca non solamente allo studio di ciò che può avere davvero scritto l'autore, ma a studiare anche le diverse letture e utilizzazioni del testo. In questo contributo presento perciò il manoscritto curato da Bondì Testario, noto come il manoscritto L, esponente esemplare della tradizione manoscritta italiana di quest'enciclopedia, inquadrandolo nel contesto storico e mettendolo in relazione con la tradizione francese
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Structural behavior of traditional Dieh-Dou timber main frame
No full textUnder different combinations of horizontal and vertical loads, a total of three static cyclic tests were conducted to investigate the in-plane structural behaviour of the traditional Dieh-Dou timber frame. Typical deformation patterns include column rocking, joint rotation around the primary beam-column and column Dou-column regions, vertical shear around the upper and lower end of column mortise, embedment around primary beam-column regions and vertical shearing around the mortise regions of the Dou members. Visible deformation generally began from 1/30 rad onwards. Column restoring force contributed mainly to the main frame’s moment resistance when displacement is small. When frame deformation exceeds 1/50 rad, bending moment from the primary beam dominated the frame’s global restoring force. Hence, column restoring force and the primary beam-column connection generally undertake the primary moment-resisting mechanism while the complex bracket structures above the primary beam play a secondary role. Base on embedment theory and semi-rigid spring model, a new theoretical model was developed to estimate the global behaviour for the global system of Dieh-Dou main frame. The current model can only estimate the initial and secondary stiffness as the spring stiffness are assumed to behave bi-linearly. Hence, it is unable to predict the out-of-plane failure phenomena and ultimate failure load at this moment. Although the prediction tends to be on the conservative side, the predicted model is generally in good agreement with observed results
