Performativities, Virtualities, Abstractions, and Cunningham's BIPED
Get PDFThis thesis explores the complex relations between subjective perception and dance movements, mainly exemplified by drawing on two short extracts from Merce Cunningham's choreography BIPED (1999). The central aim of the study is to formulate a performative phenomenological inquiry, which moves beyond an identification of essences, and towards an understanding of the lived experience of a dance performance as being grounded on iterations of the "abstract". The concept of the abstract primarily signifies an alternative mode of understanding Henry Bergson's notion of duration. Considering Gilles Deleuze's reading of Bergson's intuition as a method to divide the experience of a lived present into a temporal difference in kind between the virtual and the actual, this thesis suggests a complementary division of duration into virtual and actual kinds of abstraction.
In addition to Bergson's method of intuition, the discussion is phenomenologically rooted in Maurice Merleau-Ponty's concept of the body image and Gaston Bachelards idea of non-causal reverberation. As with the case of intuition, those phenomenological concepts are applied unconventionally. Rather than serving as a pre-objective ontological basis for an analytical and scientific understanding of subjective embodiment, the notion of a reverberating body image is here treated as a form of mimesis, performatively constituted through symbolic and representational practices. Hence, in phenomenological terms, the rationale of the thesis is predominantly sustained by the philosophy of Ernst Cassirer, arguing that reality cannot be approached directly, but only through the concept of the symbol.
The viewpoint from where I speak has performative cybernetic characteristics, continuously and dynamically transgressing boundaries and reconstituting itself through iterative and citational practices. Additionally, as I move between the analytical and the intuitive, as well as between the virtual and the actual, the formal structure of the thesis corresponds to a liminal transformation of the speaking subjectivity
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Introduzione
No full textNegli studi sui consumi, l’ambito della cultura materiale ri-veste grande importanza nell’associare alle dinamiche di con-sumo significati che vanno oltre la sfera della comunicazione, per avvicinarsi ad una visione degli oggetti e delle merci come elementi di mediazione simbolica, come strumenti utili quindi ad esplicitare i valori individuali e sociali.
Verona da tempo si occupa del tema della cultura materiale focalizzando l’attenzione ed allargando l’analisi ad ambiti diversi o correlati a quello dei consumi. Si veda, ad esempio, le rifles-sioni e gli studi sul corpo e sul vintage (Setiffi F. (2009), La mi-stica della merce, QuiEdit, Verona; Viviani D. (2010), Il corpo dei giovani, FrancoAngeli, Milano; Secondulfo D. (2012), So-ciologia del consumo e della cultura materiale, FrancoAngeli, Milano).
Questo lavoro nasce con l’intento di arricchire questa rifles-sione introducendo ed analizzando un ulteriore elemento della cultura materiale, il cibo, che affiora oggi come aspetto di estrema rilevanza nel contesto sociale
Search for the rare decay D+ -> D(0)e(+)nu(e)
No full textKolcu, Onur Buğra (Arel Author)Using a data set with an integrated luminosity of 2.93 fb(-1) collected at root s = 3.773 GeV with the BESIII detector operating at the BEPCII storage rings, we search for the rare decay D+ -> D(0)e(+)nu(e). No signal events are observed. We set the upper limit on the branching fraction for D+ -> D(0)e(+)nu(e) to be 1.0 x 10(-4) at the 90% confidence level
Measurements of the absolute branching fractions for D-s(+) -> eta e(+)nu(e) and D-s(+) -> eta ' e(+)nu(e)
Get PDFBy analyzing 482 pb(-1) of e(+)e(-) collision data collected at root s = 4.009 GeV with the BESIII detector at the BEPCII collider, we measure the absolute branching fractions for the semileptonic decays D-s(+) -> eta e(+)nu(e) and D-s(+) -> eta ' e(+)nu(e) to be B(D-s(+) -> eta e(+)nu(e)) = (2.30 +/- 0.31 +/- 0.08)% and B(D-s(+) -> eta ' e(+)nu(e)) = (0.93 +/- 0.30 +/- 0.05)%, respectively, and their ratio B(D-s(+) -> eta ' e(+)nu(e)) / B(D-s(+) -> eta ' e(+)nu(e)) = 0.40 +/- 0.14 +/- 0.02, where the first uncertainties are statistical and the second ones are systematic. The results are in good agreement with previous measurements within uncertainties; they can be used to determine the eta-eta' mixing angle and improve upon the D-s(+) semileptonic branching ratio precision
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
Get PDFBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Search for the decay D-s(+) -> gamma e (+) nu(e)
No full textKolcu, Onur Buğra (Arel Author)A search for the rare radiative leptonic decay D-s(+) -> gamma e(+)nu(e) is performed for the first time using electron-positron collision data corresponding to an integrated luminosity of 3.19 fb(-1), collected with the BESIII detector at a center-of-mass energy of 4.178 GeV. No evidence for the D-s(+) -> gamma e(+)nu(e) decay is seen, and an upper limit of beta(D-s(+) -> gamma e(+)nu(e)) 0.01 GeV
