Dimensions et dynamique de la coordination des soins de ville : une analyse économique
2019
Cet article vise à clarifier la notion de coordination en santé, à expliciter ses différentes dimensions et à revenir sur son statut dans un processus de production de soins. Une appréhension plus fine de la coordination permet de mieux analyser le bien-fondé, les difficultés des coordinations promues par les politiques de santé. Nous nous appuyons à la fois sur des études de terrain menées auprès de réseaux, de dispositifs de télémédecine et de MSP, et sur des approches théoriques de la coordination couvrant différents courants de l’économie des organisations.
On the Returns to Invention within Firms: Evidence from Finland
2018
International audience; In this paper we merge individual income data, firm-level data, patenting data, and IQ data in Finland over the period 1988–2012 to analyze the returns to invention for inventors and their coworkers or stakeholders within the same firm. We find that: (i) inventors collect only 8 percent of the total private return from invention; (ii) entrepreneurs get over 44 percent of the total gains; (iii) bluecollar workers get about 26 percent of the gains and the rest goes to white-collar workers. Moreover, entrepreneurs start with significant negative returns prior to the patent application, but their returns subsequently become highly positive.
Volatiles in pantellerite magmas: A case study of the Green Tuff Plinian eruption (Island of Pantelleria, Italy)
2013
Abstract The Green Tuff (GT) Plinian eruption, the largest in magnitude at Pantelleria, erupted 3 to 7 km3 DRE of pantellerite magma and a small volume of trachyte. Fifty-nine anorthoclase-hosted melt inclusions from the two basal pumice members were analyzed by FT-IR spectroscopy in order to assess the pre-eruptive H2O content in the pantellerite melt. Microanalytical methods were used to determine major element, Cl, F and S contents. Melt inclusions and glassy groundmasses have a nearly homogeneous pantelleritic composition (peralkaline index = 1.9-2.2) and variable water contents ranging from 1.4 to as high as 4.2 wt %, i.e. much higher than the 1.4 wt % of earlier published studies. The…
Análisis de la producción y el consumo de información en los artículos españoles sobre bibliometría
1996
We analyze Spanish production of papers on bibliometrics published in Spanish scientific journals and the use of information through the method of bibliographic reference analysis. Publications have been obtained from IME, ICYT and ISOC databases. The number of papers was 101 , with 1848 citations. The most important citations are to journal articles and Spanish publications, but <i>Scientometrics</i> is the most cited journal. Results seem to show that bibliometrics is a young discipline in our country, with an important role of classic authors. Difficulties of access to foreign bibliography produce a high use of Spanish publications. Medicine and Psychology are the most influe…
Speech treatment in nemaline myopathy: A single-subject experimental study
2020
Abstract Purpose The objective of this work was to verify the efficacy of a treatment based on myofunctional therapy techniques which aimed to improve the tongue strength, precision, and speed of a ten-year-old girl with nemaline myopathy (NM) and the repercussions of this therapy on her speech intelligibility. NM is a rare congenital muscle disorder that causes extreme muscle weakness, especially in the face and neck, as well as severe dysarthria and dysphagia, although this does not affect the nervous system or cognitive development. Method This was a single-subject experimental study which used an interrupted pre- and post-treatment time-series design, and which applied autoregressive in…
Local Capacity $H_{\infty}$ Control for Production Networks of Autonomous Work Systems With Time-Varying Delays
2010
This paper considers the problem of local capacity H∞ control for a class of production networks of autonomous work systems with time-varying delays in the capacity changes. The system under consideration is modeled in a discrete-time singular form. Attention is focused on the design of a controller gain for the local capacity adjustments which maintains the work-in-progress (WIP) in each work system in the vicinity of planned levels and guarantees the asymptotic stability of the system and reduces the effect of the disturbance input on the controlled output to a prescribed level. In terms of a matrix inequality, a sufficient condition for the solvability of this problem is presented using …
Colon Cancer Stem Cells Dictate Tumor Growth and Resist Cell Death by Production of Interleukin-4
2007
A novel paradigm in tumor biology suggests that cancer growth is driven by stem-like cells within a tumor. Here, we describe the identification and characterization of such cells from colon carcinomas using the stem cell marker CD133 that accounts around 2% of the cells in human colon cancer. The CD133(+) cells grow in vitro as undifferentiated tumor spheroids, and they are both necessary and sufficient to initiate tumor growth in immunodeficient mice. Xenografts resemble the original human tumor maintaining the rare subpopulation of tumorigenic CD133(+) cells. Further analysis revealed that the CD133(+) cells produce and utilize IL-4 to protect themselves from apoptosis. Consistently, trea…
The Selective Impairment of Phonological Processing in Speech Production
2000
We report the naming performance of a patient (DM) with a fluent progressive aphasia who made phonological errors in all language production tasks. The pattern of errors in naming was strikingly clear: DM made very many phonological errors that resulted almost always in nonword responses. The complete absence of semantic errors and the very low ratio of formal errors relative to nonword errors (1.6:30.3) in DM's performance are discussed in the context of recent claims about the nature of naming deficits in fluent aphasics. We argue that DM's performance makes highly improbable the claim that fluent aphasia results from global lesions affecting all levels of the lexical access system equall…
First results of a European multi-center registry of patients with anorectal malformations.
2013
Background: The European consortium on anorectal malformations (ARM-NET) was established to improve the health care of patients and to identify genetic and environmental risk factors. The aim of the present study was to present the first results on clinical data of a large European cohort of ARM patients based on our registry. Methods: In 2010, the registry was established including patient characteristics and data on diagnosis, surgical therapy, and outcome regarding complications. Patients born between 2007 and 2012 were retrospectively added. A descriptive analysis of this cohort was performed. Results: Two hundred and three ARM patients were included. Syndromes or chromosomal abnormalit…
Stochastic Scheduling of Production Orders Under Uncertainty
2017
This paper attempts to solve the problem of searching minimum production order completion time variants by means of stochastic logical structures with all cost curve descent points and corresponding minimum-cost schedules. The analysis presented in this paper considers scheduling of unique and small batch production, predominantly to order, which accounts for changing requirements of the customer, the complexity and long production process makespan including its technical preparation. Scheduling of production order was performed by means of GAN networks and employed the concept of soft relations. The cost/time relation analysis is based on two-node network models using the cost curve. A new…
