The World Hobbit Project in Finland : Audience responses and transmedial user practices

2016

This article examines audience engagement with The Hobbit fantasy film trilogy as a participatory and transmedial experience. To do so, we use the data collected by The World Hobbit Project in order to investigate the transmedial user practices of the Finnish audience of the trilogy. We will, firstly, look at what kinds of transmedial user practices – and transmedia users – emerge from our data. Secondly, we will ask the following questions: How do transmedia users receive and experience the films? What are the meanings assigned to The Hobbit films and the fantasy texts and user practices related to them, and what do these meanings tell of the broader meanings and uses of fantasy? Doing so,…

Utilisation de systèmes à base de folksonomies dans un processus de veille : propositions pour l'organisation et l'exploitation des informations coll…

2009

L'utilisation de folksonomies dans le cadre d'un processus de veille est un phénomène qui peu à peu est intégré aux pratiques de la veille sur l'Internet. Les folksonomies lorsqu'elles sont considérées comme sources d'information présentent un grand intérêt dans la mesure où elles permettent d'identifier et de surveiller l'émergence de nouveaux concepts ainsi que leurs représentations. Leur dimension collaborative et sociale facilite l'identification de cibles et d'experts. La diversité des ressources décrites au moyen de folksonomies permet d'élargir le champ des recherches d'information à des domaines parfois mal couverts par les outils plus traditionnels que sont les moteurs de recherche…

Monte Carlo simulation of many-arm star polymers in two-dimensional good solvents in the bulk and at a surface

1991

A Monte Carlo technique is proposed for the simulation of statistical properties of many-arm star polymers on lattices. In this vectorizing algorithm, the length of each arml is increased by one, step by step, from a starting configuration withl=1 orl=2 which is generated directly. This procedure is carried out for a large sample (e.g., 100,000 configurations). As an application, we have studied self-avoiding stars on the square lattice with arm lengths up tol max=125 and up tof=20 arms, both in the bulk and in the geometry where the center of the star is adsorbed on a repulsive surface. The total number of configurations, which behaves asN∼l γ G–1μ fl , whereμ=2.6386 is the usual effective…

Model compound synthesis for the structure determination of new unknown planar aromatic compounds originating from pulp mill

1991

Abstract Several model compounds have been synthesized for verification of the structures of new unknown planar aromatic compounds (UPACs) observed in high-resolution gas chromatography/low-resolution mass spectrometry analyses of the polychlorodibenzodioxins (PCDDs) and polychlorodibenzofurans (PCDFs) in pulp mill products, effluents, sediments and mussels. The mass spectra of synthetic alkyl polychlorodibenzofurans (C6-PCDFs) were different, but those of alkyl polychlorobibenzyls (C5-PCBBs) were very similar compared to the spectra of UPACs.

Exceptional Configurations of Quantum Walks with Grover’s Coin

2016

We study search by quantum walk on a two-dimensional grid using the algorithm of Ambainis, Kempe and Rivosh [AKR05]. We show what the most natural coin transformation -- Grover's diffusion transformation -- has a wide class of exceptional configurations of marked locations, for which the probability of finding any of the marked locations does not grow over time. This extends the class of known exceptional configurations; until now the only known such configuration was the "diagonal construction" by [AR08].

1984

Alkaline hydrolyses of anionic phenyl esters such as 4-acetoxy-3-nitrobenzoic acid and 4-butyryloxy-3-nitrobenzoic acid were examined in the presence of cationic and polymeric liposomes, liposomes of low molecular weight compounds, and micelles. All the additives accelerate the reaction due to the hydrophobic interaction between substrates and additives and the electrostatic interaction both between substrates and additives and between OH− and additives. In the Arrhenius plots of the reactions catalyzed by the liposomes, discontinuous regions were observed due to the phase transition of liposomes from the gel state to the liquid crystal state. Activation parameters ΔH≠, ΔS≠ and ΔV≠ for thes…

Catalytic enantioselective Friedel–Crafts alkylation at the 2-position of indole with simple enones

2007

Abstract A procedure for the enantioselective alkylation of indole at the 2-position with simple non-chelating enones is described for the first time. Reaction between 4,7-dihydroindole and enones in the presence of zirconium(IV)–BINOL complexes, followed by a p -benzoquinone oxidation gives indoles alkylated at the 2-position with good yields and moderate enantioselectivities.
