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…
Architettura e urbanistica, presupposti e partecipazione
2012
In analysing the relationship between architecture and urban planning, this paper starts from Leonardo Benevolo’s declaration (in 1963) that defines the latter as “a part of politics required to concretize each operational program”. So, while waiting for the long expected reform, urban planning – once as well as today – needs a complete overhaul to get a better understanding of its role and relationship with politics. The other reference is to one of the founders of this field of research, Patrick Geddes, and his definition of “civic science” (1915). This allows us to stress how modern Geddes’ urban and social planning was. The subject is analysed at its various historical stages, and the m…
I tempi di lavoro e di riposo nel diritto dell'Unione Europea
2017
L’articolo analizza la normativa europea in materia di orario di lavoro (dir. 2003/88/CE) per come interpretata dalla Corte di Giustizia. Più in particolare vengono discusse le nozioni di orario e tempi di lavoro e la regolamentazione di ferie, lavoro notturno, riposi giornalieri e settimanali, e le discipline speciali; specifica attenzione è dedicata alle deroghe che secondo la direttiva possono essere apportate dall’autonomia collettiva ed individuale (“opt-out”) alla disciplina legale, per sottolineare come il diritto dell’Unione abbia determinato una marcata liberalizzazione dei tempi di lavoro. The present work analyses the EU legislative framework on working time (dir. 2003/88/EC) and…
Which status for sensoric based discourses on digital social networks? Methodological reflections based on a corpus of wine descriptions in French an…
2019
International audience; [Context] The rise of digital humanities, embracing the expansion of digital speech production of western societies, imposes to reconsider the status of textual data – especially for specialized discourses (Lerat 1995, Petit 2010), for which written discourse has always been the most analyzed form of language use. Siever (2015: 85-86) has already raised the issue of the very nature of digital discourses in terms of medium, such as defined alongside the traditional oral-written-continuum (Koch & Oesterreicher 1994: 528). This led to a necessary theoretical and methodological shift giving priority to the conceptual level as embodied in the distance-proximity paradigm (…
Application of neural networks in diagnostics of chemical compounds based on their infrared spectra
2017
Abstract The paper presents possibilities of using the so-called „finger-print“ identification method and artificial neural network (ANN) for diagnosis of chemical compounds. The construction of a tool specifically developed for this purpose and the ANN, as well as the required conditions for its proper functioning were described. The identification of chemical compounds was tested in two different ways for proving correctness of the assumptions. First of all, initial studies were carried out with the objective to verify the proper functioning of the developed procedure for IR spectrum interpretation. The second research stage was to find out how the properties of artificial neural networks…

BODIPY atropisomer interconversion, face discrimination, and superstructure appending
2016
International audience; A strategy was developed to append sterically hindered apical pickets on both faces of the BODIPY platform to prevent stacking and aggregation. Ortho-substitution of both the meso-phenyl ring and the boron-bound catechol affords the right directionality to append pickets, achieve face discrimination, featuring two inter-convertible atropisomers, and is reminiscent of the picket-fence strategy in porphyrins.
Spectroscopy of short-lived radioactive molecules
2020
Molecular spectroscopy offers opportunities for the exploration of the fundamental laws of nature and the search for new particle physics beyond the standard model1–4. Radioactive molecules—in which one or more of the atoms possesses a radioactive nucleus—can contain heavy and deformed nuclei, offering high sensitivity for investigating parity- and time-reversal-violation effects5,6. Radium monofluoride, RaF, is of particular interest because it is predicted to have an electronic structure appropriate for laser cooling6, thus paving the way for its use in high-precision spectroscopic studies. Furthermore, the effects of symmetry-violating nuclear moments are strongly enhanced5,7–9 in molecu…
Recurrent lumbar disc herniation: Is there a correlation with the surgical technique? A multivariate analysis
2019
Purpose: The recurrence of a lumbar disc herniation (LDH) is a common cause of poor outcome following lumbar discectomy. The aim of this study was to assess a potential relationship between the incidence of recurrent LDH and the surgical technique used. Furthermore, we tried to define the best surgical technique for the treatment of recurrent LDH to limit subsequent recurrences. Materials and Methods: A retrospective study was conducted on 979 consecutive patients treated for LDH. A multivariate analysis tried to identify a possible correlation between (1) the surgical technique used to treat the primary LDH and its recurrence; (2) technique used to treat the recurrence of LDH and the secon…
Synthesis and Structure Elucidation of Novel Spirooxindole Linked to Ferrocene and Triazole Systems via [3 + 2] Cycloaddition Reaction
2022
In the present work, a novel heterocyclic hybrid of a spirooxindole system was synthesized via the attachment of ferrocene and triazole motifs into an azomethine ylide by [3 + 2] cycloaddition reaction protocol. The X-ray structure of the heterocyclic hybrid (1″R,2″S,3R)-2″-(1-(3-chloro-4-fluorophenyl)-5-methyl-1H-1,2,3-triazole-4-carbonyl)-5-methyl-1″-(ferrocin-2-yl)-1″,2″,5″,6″,7″,7a″-hexahydrospiro[indoline-3,3″-pyrrolizin]-2-one revealed very well the expected structure, by using different analytical tools (FTIR and NMR spectroscopy). It crystallized in the triclinic-crystal system and the P-1-space group. The unit cell p…
