Secret versus public reserve price in an “outcry” English procurement auction: Experimental results
2015
Abstract In a set of human experiments, we analyze the impact of the buyer׳s reserve price policy in an online open outcry reverse auction. We measure the impact of revealing or not the reserve price on the buyer׳s expected cost when suppliers may be risk-averse. Results confirm that the optimal public reserve price policy dominates for the buyer when the lowest cost supplier is weakly risk-averse but in contrast with theory, the secret reserve price policy does not dominate when he becomes very risk-averse. Analysis of strategic suppliers׳ bidding behavior shows, in conformity with theory, that they react to the secret reserve price and are more aggressive when they are more risk-averse. T…
Early cardiovascular events in women with a history of gestational diabetes mellitus
2016
International audience; Background: The effect of gestational diabetes mellitus (GDM) on cardiovascular diseases (CVD) is not assessed within the first 10 years postpartum, regardless of subsequent diabetes. The aim of this study was to determine the risk of CVD events related to GDM within 7 years of postpartum.Methods: This nationwide population-based study of deliveries in 2007 and 2008 with a follow-up of 7 years was based on data from the French medico-administrative database. Two groups were formed: women with a history of GDM and women without GDM or previous diabetes. CVD included angina pectoris, myocardial infarction, stroke, heart bypass surgery, coronary angioplasty, carotid end…
Modeling NAFLD Disease Burden in China, France, Germany, Italy, Japan, Spain, United Kingdom, and United States for the period 2016-2030
2018
Background & Aims: Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are increasingly a cause of cirrhosis and hepatocellular carcinoma globally. This burden is expected to increase as epidemics of obesity, diabetes and metabolic syndrome continue to grow. The goal of this analysis was to use a Markov model to forecast NAFLD disease burden using currently available data. Methods: A model was used to estimate NAFLD and NASH disease progression in eight countries based on data for adult prevalence of obesity and type 2 diabetes mellitus (DM). Published estimates and expert consensus were used to build and validate the model projections. Results: If obesity and…
Analysing the Spanish smoke-free legislation of 2006: a new method to quantify its impact using a dynamic model.
2011
Background: There are many models that study aspects of smoking habits: the influence of price, tax, relapse time, and the effects of prohibition. There are also studies examining the effects of the Spanish smoke-free law. We wanted to build a model able to separate the effect of the law from the pre-law evolution of smoking habits. Methods: Using data from the Spanish Ministry of Health and Social Policy, we developed a dynamic model of tobacco use. The model projects the evolution over time of the number of non-smokers, smokers and ex-smokers before 2006. Then, we compared the predictions of the model with data for the years after the law came into force, 2006 and 2009. Results: We show t…

2005
Antecedentes: Se presenta la fase III del estudio ISAAC (International Study of Asthma and other Allergies in Childhood) en escolares de 6-7 años de ocho áreas españolas para estimar la tendencia temporal y variaciones geográficas de los síntomas de rinitis alérgica. Material y método: Se comparan las prevalencias de síntomas de rinitis alérgica entre la fase I y fase III, efectuadas entre los años 1993-1994 y 2001-2002, mediante un cuestionario estandarizado y validado según metodología ISAAC, cumplimentado por los padres de los escolares. Participaron ocho centros de Asturias, Barcelona, Bilbao, Cartagena, Castellón, Madrid, Pamplona y Valencia. Se empleó la regresión de Poisson en el aná…
Trends over Time in Dental Caries status in Urban and Rural Thai Children.
2017
Background Historically, the prevalence of dental caries was higher in urban areas than rural areas of Thailand. This study aim to examine the time trends in caries status in children in Thailand. Material and Methods Linear regression was used to examine trend of dental caries prevalence and mean number of teeth with caries, filled and missing due to caries (dmft/DMFT) in urban and rural, of 3-, 5-6 and 12-year olds from seven Thailand National Oral Health Surveys conducted approximately every 5 years from 1977 to 2012. Results There were declines in the caries prevalence and mean dmft/DMFT in every age group. Significant results were observed in the mean dmft of 3 year-olds and the mean D…

Tobacco Use Documenting Policy and Its Association With Pupils’ Smoking and Their Perception of the Enforcement of School Smoking Bans in Finland
2014
Finnish national data sets on schools (N = 496) and pupils (N = 74,143; 14–16 years) were used to study whether a systematic documenting policy for the violations of school smoking bans was associated with pupils’ smoking and their perceptions on the enforcement of smoking bans. Attending a school with a systematic documenting policy was associated with perceptions that smoking is prohibited and restrictions monitored, with lower levels of smoking in the vicinity of the school during the school day, but not with smoking prevalence. Findings suggest that a consistent documenting policy could be an effective tool for reducing pupils’ smoking in schools.
Occurrence of fumonisins B1 and B2 in broa, typical Portuguese maize bread
2007
Fumonisin B1 (FB1) and fumonisin B2 (FB2) are mycotoxins mainly produced by Fusarium verticillioides, and Fusarium proliferatum, fungi species most commonly isolated from maize. The natural occurrence of FB1 and FB2 in broa, typical Portuguese maize bread, was evaluated in 30 samples. Twenty five were found positive with levels ranging from 142 to 550 [mu]g kg- 1. The limit established by the European regulations was exceeded by 27% of the samples. The tolerable daily intake for fumonisin B1, and B2, alone or in combination, for all of the analysed samples, was lower than 2 [mu]g kg- 1 body weight per day established by the European Commission. http://www.sciencedirect.com/science/article/B…
«Que en estos nuestros reinos llamábamos…»: a la búsqueda de una naturalización coeva de títulos y fórmulas de tratamiento en la traducción de la dra…
2019
La traducción de textos no-contemporáneos, ‘diacrónicos’, se puede plantear desde la lealtad romántica al original hasta la absoluta domesticación. Centrándonos en la onomástica de los títulos heredados y adquiridos y en las fórmulas de tratamiento, proponemos una naturalización histórica y cultural, de modo que la reacción del público ante la puesta en escena de la traducción sea lo más equivalente posible a la del público de la cultura de partida, hoy en día. La parte teórica arranca con la presentación y explicación de lo que entendemos como tres modos básicos de traslación, junto con la argumentación de nuestra propuesta metodológica. A continuación, se expone una taxonomía de títulos h…
