Associations between food consumption patterns and saliva composition: Specificities of eating difficulties children
2017
Identifying objective markers of dietwould be beneficial to research fields such as nutritional epidemiology. As a preliminary study on the validity of using saliva for this purpose, and in order to explore the relationship between saliva and diet, we focused on clearly contrasted groups of children: children with eating difficulties (ED) receiving at least 50% of their energy intake through artificial nutrition vs healthy controls (C). Saliva of ED and C children was analyzed by various methods (targeted biochemical analyses, 2-D electrophoresis coupled to MS, 1H NMR) and their diet was characterized using food frequency questionnaires, considering 148 food items grouped into 13 categories…
Assessing alcohol consumption through wastewater-based epidemiology: Spain as a case study
2020
Background In this study, an alternative and complementary method to those approaches currently used to estimate alcohol consumption by the population is described. This method, known as wastewater-based epidemiology (WBE), allows back-calculating the alcohol consumption rate in a given population from the concentrations of a selected biomarker measured in wastewater. Methods Composite (24-h) wastewater samples were collected at the inlet of 17 wastewater treatment plants located in 13 Spanish cities for seven consecutive days in 2018. The sampled area covered 12.8% of the Spanish population. Wastewater samples were analyzed to determine the concentration of ethyl sulfate, the biomarker use…
“Natural wages dynamics in a Ricardian growth model”
2006
Ricardian growth models are generally built on the assumption of a constant natural wage. Such an assumption conceals the fact that classical economists were aware that in growing economies workers' normal pattern of consumption steadily rise both in terms of quantity and quality. In the first part of the chapter we gather some classical hints on the relationship between economic growth and natural wages in order to provide a rational reconstruction of the classical point of view on natural wage dynamics. In the second part of the chapter we propose a formal analysis of the dynamics of a Ricardian model with endogenous natural wage
Identificación con clubes y cultura futbolística en España. [Teams identification and football culture in Spain].
2013
Pese a la enorme relevancia del futbol en la sociedad espanola, algunas de sus pautas y procesos caracteristicos han sido poco examinados por la investigacion sociologica. Este articulo presenta una investigacion sobre la identificacion con los principales clubes de futbol en la sociedad espanola e incluye un analisis de los dos principales componentes de la cultura futbolistica de sus aficionados, esto es, la vinculacion y el compromiso personal con el club. El estudio se basa en una encuesta representativa de la poblacion espanola realizada en 2007 por el Centro de Investigaciones Sociologicas (CIS) que conto con una muestra de 2.473 entrevistas. Los resultados obtenidos ponen de manifies…
Regional Inequalities in Consumption Patterns: A Multilevel Approach to the Case of Italy
2007
Summary The main aim of this paper is to evaluate the disparities in the Italian regions on the demand side. In more detail, an attempt will be made to find if the consumption behaviour of Italian households is different in the regions. With this in mind, Istat's 2000 Italian Family Budget data set was analysed. The data in question, which were collected through a two-stage sample over Italy's 20 regions, contains information regarding the expenses of approximately 23,000 households. In this analysis, both households and regions are considered as units: households are nested in the regions so that the basic data structure is hierarchical. In order to take this hierarchical structure into ac…
Stability of consumption pattern in two seed eating carabid species
2017
SPEGESTADDOCT INRA; Carabids can eat a substantial amount of seeds of weeds per day and are considered as credible biocontrol agents for the regulation of weeds in arable fields. Carabids species belong to either granivore, omnivore or carnivore trophic guilds and we expected each of these to have specific patterns of weed seed consumption and specific responses to biotic interactions. These differences will impact the total predation rate of a carabid community and may also explain why it is difficult to predict the efficiency of carabid biocontrol service. To test this expectation, we looked at the consumption pattern of two species of carabids species common in arable fields, one known a…
