Déréglementation, sécurité et prévision d’accidents extrêmes : le cas du fret ferroviaire français
2010
The deregulation of rail freight has been considered, for long time, as a factor of safety reduction. This article aims to show that, for the moment, one cannot consider that deregulation of rail freight has a significant negative impact on safety in France. Following KJELLÉN (2000), we looked if it's possible to know the periodicity of extreme accidents in this sector.
La scoperta di un paradigma complesso. L'«Unternehmen» nel diritto commerciale e nella dottrina austro-tedesca del primo Novecento
2010
Dai primi anni del Novecento, senza una precisa definizione legislativa, senza un tessuto normativo coerente ed univoco, la scienza giuridica austro-tedesca ripensò in profondità la nuova realtà economico-sociale dell’Europa industriale, scoprendo e giuridicamente rappresentando, in tempo di «individualismo atomizzante», la dimensione collettiva ed organizzativa del fenomeno imprenditoriale. Il diritto patrimoniale, fino ad allora terreno privilegiato della proprietà, si impregnava di diritto dell’economia, con al centro l’«Unternehmen», quale paradigma collettivo e complesso che, secondo il messaggio divulgato da Ohmeyer, Pisko, Müller-Erzbach, Isay, Geller, ripudiava ogni chiave di lettur…
A new cell for the study of in situ chemical reactions using X-ray absorption spectroscopy
2005
An in situ cell for reductive and oxidative treatments at different temperatures that allows the possibility of recording data as a function of temperature has been designed and constructed for X-ray absorption experiments at the GILDA beamline BM08 of ESRF. The cell is linked to a mass quadrupole spectrometer providing control of the reaction gases and monitoring of the products. The apparatus allows measurements to be performed both in transmission and fluorescence geometry. The cell was tested by studying the CO oxidation reaction promoted by a Pt/ceria-zirconia-supported catalyst. The CO(2) yield is correlated with the structural results confirming the existence of a strong metal-suppor…
Les privatisations de l'éducation
2019
International audience; Les processus de privatisation « en » éducation et « de » l'éducation concernent désormais la plupart des pays du monde. Dans un contexte de mondialisation et d'internationalisation accrues des systèmes éducatifs, la mise en oeuvre, ces dernières décennies, de mesures spécifiques de privatisation, le développement d'un secteur marchand de l'éducation, mais aussi des évolutions sociétales de fond concernant les notions d'individualisme et d'individu interrogent d'une nouvelle manière les enjeux liés aux privatisations.La promotion des intérêts privés est-elle compatible avec un processus d'éducation ? Induit-elle irrémédiablement, par exemple, une conception utilitari…
Effectual tactics in digital intrapreneurship: A process model
2020
Abstract Uncertainty and the pursuit of new ventures are intricately linked. Digital technologies open up new ways for uncertainty handling in the pursuit of novelty. In this paper, we develop a process model that traces the dynamics among uncertainty, digitally enabled tactics, and organizational novelty. The model points to the potential of technologies that are evocative, disposable, and responsive for venturing in complex, uncertainty-ridden contexts. Our research builds on extant conceptualizations of complexity in innovation journeys, in conjunction with perspectives on effectual entrepreneurial tactics. Empirically, we investigate uncertainty handling through a longitudinal case stud…
Inter-string arrays of bimetallic assemblies with alternative Cu2+-Cl-Cu2+ and Cu-NC-M (M = Co3+, Fe+3, Cr+3) bridges: syntheses, crystal structure, …
2004
Three bimetallic assemblies with alternate homometallic bridges through chloride ligands and heterometallic bridges through cyanide ligands of formula [(323)(2)Cu(2)(Cl)M(CN)(6)](n).2n(H(2)O), where 323 = N,N'-bis(3-aminopropyl)ethylenediamine and M = Co(3+) for 1, Fe(3+) for 2, and Cr(3+) for 3, were synthesized. They have been characterized structurally, analytically, spectroscopically, and magnetically. All three assemblies crystallize in the monoclinic system in the same space group P2(1)/n, with a = 11.642(2) A, b = 10.285(3) A, c = 13.622(2) A, beta = 95.69(3) degrees, V = 1623.1(6) A(3), and Z = 4 for 1; a = 11.681(4) A, b = 10.315(3) A, c = 13.567(5) A, beta = 95.62(3) degrees, V = …
Márgenes silentes. Palabra excedida y silencio inspirado (Hofmannsthal/Blanchot)
2016
Resumen: Contra los intentos de desalojar al silencio de la posibilidad de expresión, y de vaciar a la expresión de su propio silencio, el artículo propone como tarea para nuestro mundo contemporáneo el que seamos rastreadores de silencio. La tarea no es fácil, pues el silencio decisivo no se puede escuchar, sino que se halla atesorado en el interior de las palabras y obras como su última y más inspirada verdad. Para ello toma como guía la famosa Carta de Lord Chandos (Hofmannsthal), reivindicando su silencio-en-tránsito (excedido por una nueva experiencia de la riqueza desbordante de la realidad) y las reflexiones de Blanchot en torno a la relación entre silencio e inspiración. En la segun…
Technique of transanal endoscopic microsurgery.
1988
Sessile adenomas are predominantly localized in the rectum and lower sigma. Surgical removal is indicated but often implies an invasive surgical procedure. Using conventional transanal surgical techniques, only the lower rectum can be reached and there are high rates of recurrence. The new technique combines an endoscopic view of the rectum under gas insufflation via a stereoscopic telescope with conventional surgical preparation and suturing. Adenomas can be excised using the mucosectomy technique or full-thickness-excision, whereas carcinomas should be excised using full-thickness excision with a sufficient border of healthy mucosa. In carcinomas of the sacral cavity, we remove the retror…
Do Age and Sex Play a Role in the Intraocular Pressure Changes after Acrobatic Gymnastics?
2021
To evaluate the effects of an acrobatic gymnastics (AG) training session on intraocular pressure (IOP), a familiarization session was employed to confirm the participant’s suitability for the study. Forty-nine gymnasts (63.27% females, 18–40 years old) voluntarily agreed to participate. As age, sex, baseline IOP, and central corneal thickness (CCT) were considered as potential predictors of the IOP variations, in the second session measurements of the above parameters were taken before and after 90 min of AG. A mixed-factorial analysis of variance evaluated differences. Linear regression was conducted to potentially predict the IOP variation with the exercise. After the scheduled exercise, …
