Le elezioni cantonali ticinesi del 2011. Partecipazione e orientamento di voto fra lealtà, defezione, protesta.

Cette étude scientifique, basée sur une enquête post-électorale (N=1285), vise à analyser le cas des élections du gouvernement et du parlement du Canton du Tessin qui se sont déroulées en avril 2011. Celles-ci constituent un vrai tournant dans l'histoire électorale tessinoise. D'un côté, le taux de participation a été le plus bas depuis 1920 ; d'autre part, la Lega dei ticinesi est devenu le premier parti au Conseil d'Etat avec 2 sièges sur 5. Afin d'analyser les représentations du vote, la participation ainsi que la décision de vote (choix du parti, bulletin sans dénomination du parti, déplacement de votes), nous nous sommes inspirés de la triade conceptuelle de A. O. Hirschman (loyauté, défection et prise de parole). Les résultats montrent que ce vote tessinois ne doit pas être interprété exclusivement en termes de déclin de la loyauté (par rapport à l'acte de vote et aux partis traditionnels), comme augmentation de la défection ou "prise de parole". Au contraire, mais comme une articulation complexe de ces phénomènes.

El tracista fra Josep de la Concepció: revisió historiogràfica i noves atribucions

Fra Josep de la Concepció, membre de la congregació de carmelitans descalços, va ser un dels més qualificats arquitectes amb què comptà el Principat en el segle XVII. L"interès de la seva figura es troba sobretot en el fet que la seva activitat no es va circumscriure simplement a les construccions impulsades per l"orde al qual pertanyia, sinó que s"estengué a àmbits tan diversos com els de la confecció de traces per a catedrals, esglésies parroquials, edificis civils, retaules i altres obres de naturalesa diversa, que mostren en conjunt el gran talent d"aquest artífex

Water-filtered infrared-A radiation (wIRA) is not implicated in cellular degeneration of human skin.

BACKGROUND: Excessive exposure to solar ultraviolet radiation is involved in the complex biologic process of cutaneous aging. Wavelengths in the ultraviolet-A and -B range (UV-A and UV-B) have been shown to be responsible for the induction of proteases, e. g. the collagenase matrix metalloproteinase 1 (MMP-1), which are related to cell aging. As devices emitting longer wavelengths are widely used in therapeutic and cosmetic interventions and as the induction of MMP-1 by water-filtered infrared-A (wIRA) had been discussed, it was of interest to assess effects of wIRA on the cellular and molecular level known to be possibly involved in cutaneous degeneration. OBJECTIVES: Investigation of the biological implications of widely used water-filtered infrared-A (wIRA) radiators for clinical use on human skin fibroblasts assessed by MMP-1 gene expression (MMP-1 messenger ribonucleic acid (mRNA) expression).Methods: Human skin fibroblasts were irradiated with approximately 88% wIRA (780-1400 nm) and 12% red light (RL, 665-780 nm) with 380 mW/cm(2) wIRA(+RL) (333 mW/cm(2) wIRA) on the one hand and for comparison with UV-A (330-400 nm, mainly UV-A1) and a small amount of blue light (BL, 400-450 nm) with 28 mW/cm(2) UV-A(+BL) on the other hand. Survival curves were established by colony forming ability after single exposures between 15 minutes and 8 hours to wIRA(+RL) (340-10880 J/cm(2) wIRA(+RL), 300-9600 J/cm(2) wIRA) or 15-45 minutes to UV-A(+BL) (25-75 J/cm(2) UV-A(+BL)). Both conventional Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) and quantitative real-time RT-PCR techniques were used to determine the induction of MMP-1 mRNA at two physiologic temperatures for skin fibroblasts (30 degrees C and 37 degrees C) in single exposure regimens (15-60 minutes wIRA(+RL), 340-1360 J/cm(2) wIRA(+RL), 300-1200 J/cm(2) wIRA; 30 minutes UV-A(+BL), 50 J/cm(2) UV-A(+BL)) and in addition at 30 degrees C in a repeated exposure protocol (up to 10 times 15 minutes wIRA(+RL) with 340 J/cm(2) wIRA(+RL), 300 J/cm(2) wIRA at each time). RESULTS: Single exposure of cultured human dermal fibroblasts to UV-A(+BL) radiation yielded a very high increase in MMP-1 mRNA expression (11 +/-1 fold expression for RT-PCR and 76 +/-2 fold expression for real-time RT-PCR both at 30 degrees C, 75 +/-1 fold expression for real-time RT-PCR at 37 degrees C) and a dose-dependent decrease in cell survival. In contrast, wIRA(+RL) did not produce cell death and did not induce a systematic increase in MMP-1 mRNA expression (less than twofold expression, within the laboratory range of fluctuation) detectable with the sensitive methods applied. Additionally, repeated exposure of human skin fibroblasts to wIRA(+RL) did not induce MMP-1 mRNA expression systematically (less than twofold expression by up to 10 consecutive wIRA(+RL) exposures and analysis with real-time RT-PCR). CONCLUSIONS: wIRA(+RL) even at the investigated disproportionally high irradiances does not induce cell death or a systematic increase of MMP-1 mRNA expression, both of which can be easily induced by UV-A radiation. Furthermore, these results support previous findings of in vivo investigations on collagenase induction by UV-A but not wIRA and show that infrared-A with appropriate irradiances does not seem to be involved in MMP-1 mediated photoaging of the skin. As suggested by previously published studies wIRA could even be implicated in a protective manner.

Making Space for Festival 1400-1700. Interactions of Architecture and Performance in Late Medieval and Early Modern Festivals

Las relaciones entre actos festivos y espacios arquitectónicos, y las modalidades con que las ceremonias cortesanas llegaban a modificar los centros urbanos y las residen- cias palaciegas, han sido los temas principales del congreso internacional Making Space for Festival, 14001700. Interactions of Architecture and Performance in Late Medieval and Early Modern Festivals, que tuvo lugar del 21 al 24 de marzo de 2013 en el Palacio Pesaro-Papafava de Venecia, residencia de la Universidad de Warwick en la Laguna. La Society for European Festivals Research (SEFR), entidad vinculada a esta universidad, ha promovido el encuentro junto con la Red PALATIUM financia- da por el Research Networking Programme de la European Science Fundation (ESF) (2010-2015), dedicada al estudio de las residencias palaciegas de la Edad Moderna como espacios de intercambios políticos y culturales. El tema de las jornadas nacía de la unión de los intereses científicos de los grupos organizadores, dejando lugar a temáticas diferentes como: la articulación de un mensaje festivo a lo largo del recorri- do de procesiones y entradas públicas, la financiación y los aspectos más prácticos de la puesta en escena de un evento festivo, la tipificación de ceremonias y decoraciones en determinados contextos, el intercambio cultural a través de la fiesta, o la recepción de las modificaciones de los espacios por parte de los espectadores
