The Media and Socio-Cultural Regulation of Religion

(Résumé de l'ouvrage) Originale, insolite, renaissante, l'action religieuse émergente bouscule les habitudes, ébranle les certitudes, construit ici, maintenant, l'autre monde. Peut-on courir le risque? Voilà que la question se pose et se résout en rumeurs publiques, poursuites judiciaires et tensions scolaires, lesquelles mettent à nu des mécanismes inédits d'institutionnalisation de l'expérience religieuse en modernité. As new religious movements seek to carve out their own niche in society, public controversy and opposing beliefs can spark bitter debates, and can even lead to calls for state intervention. How then do new or borderline religious groups negotiate or mediate the building of public space?

Radical cystectomy and unrinary diversion : is there a role for bowel in the fuuture?

Bladder transitional cell carcinoma (TCC) is the most frequent malignancy of the urinary tract, and its incidence is rising. The gold standard treatment of invasive TCC is radical cystectomy with configuration of urinary diversion with bowel; the need for bowel has been universally considered the prime cause of complications. Since 1960’s urologists, scientists and industry have been trying, unsuccessfully, to obviate the use of bowel with alternative materials. We provide an analysis of problems deriving from using bowel as bladder substitute, a comprehensive review of literature on previous artificial models, an analysis of benefits deriving from the ideal prosthesis.

La Baixa morbiditat perioperatòria de la prostatectomia radical laparoscòpica justifica efectuar-la en pacients majors de 70 anys

Donat l’increment en l’esperança de vida, valorem el tractament radical del càncer de pròstata en pacients & 70 anys. L’objectiu és analitzar la incidència, severitat i maneig de la morbiditat perioperatòria de la prostatectomia radical (PR) en funció de la tècnica quirúrgica. De 500 PR revisem, retrospectivament, 70 pacients & 70 anys (40 Retropúbiques i 30 Laparoscòpiques). S’empra la classificació de Clavien modificada per analitzar les complicacions. La proporció de complicacions és en PRR 57,5% i en PRL 33%. Les complicacions en la PRL són de menor gravetat. Els beneficis atribuïts a la laparoscòpia es mantenen en pacients d’edat avançada.

Delayed otogenic hydrocephalus after acute otitis media in pediatric patients: the changing presentation of a serious otologic complication.

CONCLUSIONS: The clinical presentation of otogenic dural sinus thrombosis (DST) as a complication of acute otitis media (AOM) can be masked by antibiotic treatment. Morning episodes of vomiting and/or headache, visual impairment and a history of AOM seem to be indicative of otogenic hydrocephalus. We therefore advocate that the MRI scans of patients with similar symptoms should be carefully studied to facilitate the early diagnosis of a potentially life-threatening complication. OBJECTIVE: To describe the frequency, pathognomonic signs, clinical course and outcome of otogenic hydrocephalus and DST as complications of AOM in pediatric patients. MATERIAL AND METHODS: We undertook a retrospective chart review of all pediatric patients (age 1-14 years) treated for otitis media and its complications at an academic medical center between 1999 and 2003. The main outcome measures were otologic and ophthalmologic findings and CT and MRI scans at the beginning of treatment and 3 months later. RESULTS: We report on five cases with otogenic DST following AOM. All but one of them presented initially with diplopia caused by otogenic hydrocephalus. In four cases the otologic complaints had already disappeared by the time of MRI confirmation of the diagnosis. Only one child was referred with severe otologic symptoms. Management included systemic antibiotics, short-term heparin anticoagulation and surgical decompression. In our cases, even after intensive i.v. antibiotic treatment, only surgery led to a significant improvement in the clinical condition.

Internal and External Determinants of Radical and incremental Innovation in SMEs: the case of Catalonia

There is a major concern in economic literature about innovation, which is the interaction between internal and external factors.. In this paper those activities are hypothesized as being determined by some territorial characteristics like labour skills, technological infrastructure, educational facilities, agglomeration economies and industrial structure. This assumption allows understanding why those innovative activities are not spread across space and are located into specific areas. We use a detailed survey containing microdata for 497 SMEs located in Catalonia.

Hybrid Multiscale Finite Volume method for two-phase flow in porous media

We present a novel hybrid (or multiphysics) algorithm, which couples pore-scale and Darcy descriptions of two-phase flow in porous media. The flow at the pore-scale is described by the Navier?Stokes equations, and the Volume of Fluid (VOF) method is used to model the evolution of the fluid?fluid interface. An extension of the Multiscale Finite Volume (MsFV) method is employed to construct the Darcy-scale problem. First, a set of local interpolators for pressure and velocity is constructed by solving the Navier?Stokes equations; then, a coarse mass-conservation problem is constructed by averaging the pore-scale velocity over the cells of a coarse grid, which act as control volumes; finally, a conservative pore-scale velocity field is reconstructed and used to advect the fluid?fluid interface. The method relies on the localization assumptions used to compute the interpolators (which are quite straightforward extensions of the standard MsFV) and on the postulate that the coarse-scale fluxes are proportional to the coarse-pressure differences. By numerical simulations of two-phase problems, we demonstrate that these assumptions provide hybrid solutions that are in good agreement with reference pore-scale solutions and are able to model the transition from stable to unstable flow regimes. Our hybrid method can naturally take advantage of several adaptive strategies and allows considering pore-scale fluxes only in some regions, while Darcy fluxes are used in the rest of the domain. Moreover, since the method relies on the assumption that the relationship between coarse-scale fluxes and pressure differences is local, it can be used as a numerical tool to investigate the limits of validity of Darcy's law and to understand the link between pore-scale quantities and their corresponding Darcy-scale variables.

Adjuvant or radical fractionated stereotactic radiotherapy for patients with pituitary functional and nonfunctional macroadenoma.

Purpose: To evaluate the efficacy and toxicity of stereotactic fractionated radiotherapy (SFRT) for patients with pituitary macroadenoma (PMA).Methods and Materials: Between March 2000 and March 2009, 27 patients (male to female ratio, 1.25) with PMA underwent SFRT (median dose, 50.4 Gy). Mean age of the patients was 56.5 years (range, 20.3 - 77.4). In all but one patient, SFRT was administered for salvage treatment after surgical resection (transphenoidal resection in 23, transphenoidal resection followed by craniotomy in 2 and multiple transphenoidal resections in another patient). In 10 (37%) patients, the PMAs were functional (3 ACTH-secreting, 3 prolactinomas, 2 growth hormone-secreting and 2 multiple hormone-secretion). Three (11.1%) and 9 (33.3%) patients had PMA abutting and compressing the optic chiasm, respectively. Mean tumor volume was 2.9 +/- 4.6 cm(3). Eighteen (66.7%) patients had hypopituitarism prior to SFRT. The mean follow-up period after SFRT was 72.4 +/- 37.2 months.Results: Tumor size decreased for 6 (22.2%) patients and remained unchanged for 19 (70.4%) other patients. Two (7.4%) patients had tumor growth inside the prescribed treatment volume. The estimated 5-year tumor growth control was 95.5% after SFRT. Biochemical remission occurred in 3 (30%) patients with functional PMA. Two patients with normal anterior pituitary function before SFRT developed new deficits 25 and 65 months after treatment. The 5-year survival without new anterior pituitary deficit was thus 95.8%. Five patients with visual field defect had improved visual function and 1 patient with no visual defect prior to SFRT, but an optic chiasm abutting tumor, had a decline in visual function. The estimated 5-year vision and pituitary function preservation rates were 93.2% and 95.8%, respectively.Conclusions: SFRT is a safe and effective treatment for patients with PMA, although longer follow-up is needed to evaluate long-term outcomes. In this study, approximately 1 patient with visual field defect out of two had an improved visual.

Error estimate and control in the MSFV method for multiphase flow in porous media

n this paper the iterative MSFV method is extended to include the sequential implicit simulation of time dependent problems involving the solution of a system of pressure-saturation equations. To control numerical errors in simulation results, an error estimate, based on the residual of the MSFV approximate pressure field, is introduced. In the initial time steps in simulation iterations are employed until a specified accuracy in pressure is achieved. This initial solution is then used to improve the localization assumption at later time steps. Additional iterations in pressure solution are employed only when the pressure residual becomes larger than a specified threshold value. Efficiency of the strategy and the error control criteria are numerically investigated. This paper also shows that it is possible to derive an a-priori estimate and control based on the allowed pressure-equation residual to guarantee the desired accuracy in saturation calculation.

Condiciones para una arquitectura radical

La investigación Condiciones para una arquitectura radical se ha desarrollado en el marco de la beca FI 2009-12; y también incluye una beca de movilidad BE-DGR 2009 por un período de seis meses de 2010 en Princeton University School of Architecture. Condiciones para una arquitectura radical tiene un objetivo general: trabajar las relaciones entre límite, experiencia y comunidad a partir de dos pilares: arte y tecnología. Son tres familias de conceptos y sus articulaciones complejas en el espacio común: para definir en última instancia, otros procesos posibles de gestión en la ciudad. La lucha ideológica está en pensar cual debería ser el futuro de las ciudades. El objetivo concreto de la tesis es la búsqueda de herramientas para abrir nuevos espacios en la ciudad donde materializar un cambio social y urbano. Para entender esta aproximación la investigación indaga en los momentos de acercamiento y simbiosis de la arquitectura a las tesis del arte y la tecnología: una mirada atenta a las condiciones de contexto. Se explora el cruce de algunas ideas emancipadoras que se formularon en diferentes momentos de la cultura - desde las vanguardias históricas hasta ahora- en los que se intuyó la importancia del sistema abierto -el paso del objeto al proceso- y su trasposición en arquitectura: una arquitectura y un urbanismo open source; son episodios en los que ha existido un cuestionamiento de las fronteras disciplinares y un interés por la apropiación convivencial de lo público. Algunas de aquellas ideas pueden repetirse en el contexto activo de unas nuevas condiciones.

Media exposure and internal migration-evidence from Indonesia

This paper investigates the impact of television on internal migration in Indonesia. We exploit the differential introduction of private television throughout the country and the variation in signal reception due to topography to estimate the causal effect of media exposure. Our estimates reveal important long and short run effects. An increase of one standard deviation in the number of private TV channels received in the area of residence reduces future inter-provincial migration by 1.7-2.7 percentage points, and all migration (inter and intra-provincial) by 4-7.4 percentage points. Short run effects are slightly smaller, but still sizeable and statistically significant. We also show that respondents less exposed to private TV are more likely to consider themselves among the poorest groups of the society. As we discuss in a stylized model of migration choice under imperfect information, these findings are consistent with Indonesia citizens over-estimating the net gains from internal migration.

Calculation of correction factors for ionization chamber measurements with small fields in low-density media.

The quantity of interest for high-energy photon beam therapy recommended by most dosimetric protocols is the absorbed dose to water. Thus, ionization chambers are calibrated in absorbed dose to water, which is the same quantity as what is calculated by most treatment planning systems (TPS). However, when measurements are performed in a low-density medium, the presence of the ionization chamber generates a perturbation at the level of the secondary particle range. Therefore, the measured quantity is close to the absorbed dose to a volume of water equivalent to the chamber volume. This quantity is not equivalent to the dose calculated by a TPS, which is the absorbed dose to an infinitesimally small volume of water. This phenomenon can lead to an overestimation of the absorbed dose measured with an ionization chamber of up to 40% in extreme cases. In this paper, we propose a method to calculate correction factors based on the Monte Carlo simulations. These correction factors are obtained by the ratio of the absorbed dose to water in a low-density medium □D(w,Q,V1)(low) averaged over a scoring volume V₁ for a geometry where V₁ is filled with the low-density medium and the absorbed dose to water □D(w,QV2)(low) averaged over a volume V₂ for a geometry where V₂ is filled with water. In the Monte Carlo simulations, □D(w,QV2)(low) is obtained by replacing the volume of the ionization chamber by an equivalent volume of water, according to the definition of the absorbed dose to water. The method is validated in two different configurations which allowed us to study the behavior of this correction factor as a function of depth in phantom, photon beam energy, phantom density and field size.
