Crowdfunding y Financiación de Partidos Políticos
2019
Crowdfunding is presented as a new private financial resource for parties of political parties by which citizens can participate economically in the structure of these organizations. This paper will set out some legal proposals that seek to adequately incorporate this new resource. First, we will approach the crowdfunding analysis in order to make it easier for the reader to understand this phenomenon. Secondly, it will analyze the current implementation of this tool by political parties at national and international level, pointing out some of the positive and negative aspects that can be derived from the use of this new resource. All this, with the main objective of analyzing the viabilit…
Etat de l’art et enjeux du community management sur les plateformes de Crowdfunding
2014
L'étude de cinq mois réalisée sous la direction d'Olivier Galibert par le Cimeos en collaboration avec idStarter, puis la collaboration entre septembre et octobre 2014 entre Arnaud Belorgey (porteur du projet de création d'entreprise IdStarter) et Nicolas Peirot (Jeune chercheur au CIMEOS) ont été l'occasion de dresser un état de l'art du community management dans le cadre de dispositifs de crowdsourcing et de crowdfunding, de mettre en place une observation de communautés en acte sur trois campagnes de crowdfunding, mais aussi de préciser l’offre de la société idStarter.Ce travail a donné lieu à une série d'enseignements en matière de "community management créatif".
Entrepreneurship, gender and entrepreneurial fundraising through crowdfunding
2022
Esta tesis, que lleva por título “Entrepreneurship, gender and entrepreneurial fundraising through crowdfunding”, aborda el objetivo global de entender con mayor profundidad el proceso de creación de empresas y recaudación de fondos por parte del ecosistema emprendedor. Este objetivo se articula, desde un punto de vista teórico y práctico, a través de tres capas de análisis: primero, el entorno y su relación con la creación de empresas; segundo, las características y circunstancias de los emprendedores y su influencia en la creación de empresas; y tercero, la divulgación de información en las campañas de micromecenazgo y el éxito en la recaudación de fondos. A su vez, estas tres capas de an…
Synthesis, crystal structure, DFT calculations, Hirshfeld surface, vibrational and optical properties of a novel hybrid non-centrosymmetric material …
2019
This present work undertakes the study of a novel organic–inorganic hybrid material, which has been obtained successfully by an acid-base reaction at room temperature and structurally studied by the single crystal X-ray diffraction method. (C10H15N2)2H2P2O7 crystallizes in the triclinic system with the non-centrosymmetric space group P1 with the following lattice parameters: a = 5.9159(2) Å, b = 13.8451(6) Å, c = 14.5973(5) Å, ? = 74.507(2)°, ? = 89.980(2)°, ? = 89.231(2)° with V = 1152.06(8) Å3 and Z = 2. The X-ray structural analysis supported by a detailed Hirshfeld 2D fingerprint plots has been performed to elucidate the different inter-contacts in the crystal structure mainly associate…
The first copper(I)-olefin complexes bearing a 1,3,4-oxadiazole core: Alternating-current electrochemical crystallization, X-ray experiment and DFT s…
2017
By means of alternating-current electrochemical technique, four new π-complexes, namely [Cu2(C11H10N2OS)2Br1.91Cl0.09] (1), [Cu(C11H10N2OS)NO3] (2), [Cu2(C11H10N2OS)2(H2O)2](BF4)2 (3) and [Cu2(C11H10N2OS)2(H2O)2](ClO4)2 (4), were obtained using copper(II) salts and the 2-(allylthio)-5-phenyl-1,3,4-oxadiazole (C11H10N2OS) ligand. The metal and halogen centers in 1 form Cu2X2 dimers; the N-atom from the oxadiazole ring and the Cdouble bond; length as m-dashC bond of the allyl group from the same ligand complete the copper coordination environment, giving [Cu(C11H10N2OS)X]2 isolated fragments. The ligand plays the same chelating role in 2, whereas the O (NO3) atom occupies the third position i…
Crystal structure, Hirshfeld surface analysis and DFT studies of (E)-1-(4-bromophenyl)-3-(3-fluorophenyl)prop-2-en-1-one
2018
The title halogenated organic chalcone was prepared by a Claisen–Schmidt condensation reaction. A Hirshfeld surface analysis was carried out to reveal the percentage contributions of the intermolecular interactions. A theoretical study was performed using the density functional theory (DFT) at B3LYP with the 6–311 G++(d,p) basis set level to compare with the experimental results of the X-ray analysis and UV–vis absorption analysis in term of the geometrical parameters, HOMO-LUMO energy gap and charge distributions.
Substituent effects in nitro derivatives of carbazoles investigated by comparison of low-temperature crystallographic studies with density functional…
2014
The crystal structure of 9H-carbazole, C12H9N, (I), has been redetermined at low temperature for use as a reference structure in a comparative study with the structures of 1-nitro-9H-carbazole, C12H8N2O2, (II), and 9-nitrocarbazole, C12H8N2O2, (III). The molecule of (I) has crystallographically imposed mirror symmetry (Z′ = 0.5). All three solid-state structures are slightly nonplanar, the dihedral angles between the planes of the arene and pyrrole rings ranging from 0.40 (7)° in (III) to 1.82 (18)° in (II). Nevertheless, a density functional theory (DFT) study predicts completely planar conformations for the isolated molecules. To estimate the influence of nitro-group substitution on aroma…
Support for culture via crowdfunding in question: beyond motivations, an analysis of the barriers to participate
2017
In a context of strong budgetary pressure for non-market cultural organizations and of relative slowdown of crowdfunding campaigns in this sector, this reflection aims to provide a critical analysis of these new forms of financial support for culture. After drawing up a state of the art on the levers and obstacles to participation in such financing operations, the results of a qualitative study based on 43 individuals (donors and non-donors, familiar or not with cultural practices) will be exposed to highlight the diversity of misgivings about crowdfunding, beyond the traditional barriers attached to cultural gift, and the paradoxes that these calls for generosity arouse.
The Profiles of Body Image Associate With Changes in Depression Among Participants in Dance Movement Therapy Group
2020
This mixed-methods study analyzed the body image quality of 143 patients with depression. The participants received a 20 × 75 min dance movement therapy (DMT) group treatment, sessions twice a week. Body Image Assessment (BIA) was the data collection tool, with pre-, post-, and 3-mos follow-up assessments. Pre-intervention body image quality characteristics were low energy and activity levels, discomfort, shame and disgust toward the body, tension in social interactions. On the BIA scores, a statistical method of Latent Profile Analysis was utilized to identify participant profiles in the data. The two identified profiles were participant with initial negative body image and participant wit…
Dance movement therapy for depressed clients : Profiles of the level and changes in depression
2021
This research identified participant profiles in level and changes in depression among working age (18–64 years old) clients (N = 137) diagnosed with depression, who participated in a 20-session dance movement therapy (DMT) intervention. Using Latent Profile Analysis Mild, sharply reducing depression (9%), Mild, reducing depression (58%) and Severe, reducing depression (33%) profiles were established, using Beck Depression Inventory scores gathered at pre-intervention, post-intervention, and follow-up points. At the pre-intervention point, being in full-time work was related to the Mild, sharply reducing depression profile. Being on a disability pension, having a history of one's own or a c…
