Collaborative Design Rational and Social Creativity in Cultures of Participation

2011

The rise in social computing has facilitated a shift from consumer cultures, focused on producing finished media to be consumed passively, to cultures of participation, where people can access the means to participate actively in personally meaningful problems. These developments represent unique and fundamental opportunities and challenges for rethinking and reinventing design rationale and creativity, as people acclimate to taking part in computer-mediated conversations of issues and their solutions. Grounded in our long-term research exploring these topics, this paper articulates arguments, describes and discusses conceptual frameworks and system developments (in the context of three cas…

Thermodynamic and spectroscopic study of the binding of dimethyltin(IV) by citrate at 25°C

2006

Thermodynamic (potentiometric and calorimetric) and spectroscopic ( 1 H NMR, 119 Sn Mossbauer) studies were performed in aqueous solution in order to characterize the interaction of dimethyltin(IV) cation with citrate ligand. Six species {(CH 3 ) 2 Sn(cit) - ; [(CH 3 ) 2 Sn] 2 (cit) 2 2- ; (CH 3 ) 2 Sn(cit)H 0 ; (CH 3 ) 2 Sn(cit)OH 2- ; [(CH 3 ) 2 Sn] 2 (cit)OH 0 ; [(CH 3 ) 2 Sn] 2 (cit)(OH) 2 - } were found. All the species formed in this system are quite stable and formation percentages are fairly high. For example, at pH = 7.5 and C (CH3)2Sn = C cit = 10 mmol l -1 , E% for [(CH 3 ) 2 Sn] 2 (cit)(OH) 2 - and (CH 3 ) 2 Sn(cit)OH 2- species reaches 65%. Overall thermodynamic parameters obta…

Acute Effects of Tecar Therapy on Skin Temperature, Ankle Mobility and Hyperalgesia in Myofascial Pain Syndrome in Professional Basketball Players: A…

2021

(1) Background: Myofascial pain syndrome (MPS) is a clinical condition characterized by localized non-inflammatory musculoskeletal pain caused by myofascial trigger points. Diathermy or Tecar therapy (TT) is a form of noninvasive electro-thermal therapy classified as deep thermotherapy based on the application of electric currents. This technique is characterized by immediate effects, and its being used by high performance athletes. (2) Methods: A total of thirty-two participants were included in the study who were professional basketball players. There was a 15-person Control Group and a 17-person Intervention Group. TT was applied in the Intervention Group, while TT with the device switch…

Optical quality of hyperopic and myopic phakic intraocular lenses

2013

Aims: To assess and compare the optical quality of the myopic and hyperopic implantable collamer lens (ICL) from its wavefront aberrations for different powers and pupil diameters. Settings and Design: Prospective study. Material and Methods: The wavefront aberrations of two myopic (−3 and −6 diopters (D)) and two hyperopic V4b ICLs (+3 and +6D) were measured in vitro . To assess and compare the optical quality of different powers of ICLs, we analyzed the root mean square (RMS) of total higher order aberrations (HOAs), trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration at 3- and 4.5-mm pupil. In addition, the point spread functions (PSFs) of each ICL evaluated were ca…

Intelligence stratégique et dissimulation dans les outils de géovisualisation en ligne

2014

Interactive geovisualization portals, set up on the Internet after the iconic Google Maps, are highly regarded by the public. They provide the ability to see from above the surface of our planet, and more specifically the French territory in the case of Geoportail. Yet it is forbidden to approach too close to certain objects: on national territory, some 150 sites are in fact hidden by the IGN. This paper question the relevance and efficiency of this operation imposed on the main body of production and dissemination of spatial information in France, in comparison with the means used by other countries.
