La incidencia del salario mínimo interprofesional en sectores de bajos salarios
2012
El salario mínimo es un tema que ha vuelto a cobrar actualidad. La mayoría de los análisis que se realizan al respecto se centran en determinar si su nivel tiene algún tipo de incidencia sobre el empleo. No obstante, son escasos los trabajos que abordan si efectivamente el salario mínimo cumple con su objetivo básico: mejorar las rentas de los perceptores de bajos salarios. En este trabajo abordamos precisamente esta cuestión. Para ello se analiza la evolución de los salarios en la negociación colectiva en tres sectores considerados de bajos salarios (comercio al por menor, hostelería y limpieza de locales y edificios), centrándonos en los puestos inferiores de la escala salarial. The minim…
A Smartphone App to Promote Healthy Weight Gain, Diet, and Physical Activity During Pregnancy (HealthyMoms): Protocol for a Randomized Controlled Tri…
2019
BACKGROUND: Excessive gestational weight gain is common and associated with adverse outcomes both in the short and long term. Although traditional lifestyle-based interventions have shown to mitigate excess gestational weight gain, little is known about whether mobile Health (mHealth) apps can promote healthy weight gain, diet, and physical activity during pregnancy. OBJECTIVE: The primary aim of the HealthyMoms trial is to determine the effectiveness of a smartphone app (HealthyMoms) for mitigating excess gestational weight gain during pregnancy. Secondary aims are to determine the effectiveness of the app on dietary habits, physical activity, body fatness, and glycemia during pregnancy. M…
The Protection of the Weaker Parties in the Platform Economy
2018
Known by many names – platform, sharing, peer-to-peer (p2p), collaborative economy, and so on - entirely new business models have emerged in recent years, whereby online platforms use digital technologies to connect distinct groups of users in order to facilitate transactions for the exchange of assets and services. This dramatic shift in business organisation and market structure has opened an intense debate on the persisting need for those regulatory measures that typically protect the weaker party in bilateral business-to-consumer transactions. Widespread calls for a more “levelled playing field” makes a strong argument for reconsidering the scope of regulation and delegating regulatory …
Influence of health literacy on maintenance of exclusive breastfeeding at 6 months postpartum: a multicentre study

Copyright © 2022 by the authors. Background: International organizations recommend initiating breastfeeding within the first hour of life and maintaining exclusive breastfeeding for the first 6 months. However, worldwide rates of exclusive breastfeeding for 6-month-old infants is far from meeting the goal proposed by the World Health Organization, which is to reach a minimum of 50% of infants. Education is one of the factors affecting the initiation and continuation of breastfeeding, and incidentall…
High-Resolution Nonlinear Raman-Spectroscopy in Gases
1990
0377-0486; The resolution in the Raman spectra of gases has been greatly improved by the development of the different methods of non-linear Raman scattering. When two laser beams, one of which has a tunable frequency, are focused in a sample, a stimulated Raman process occurs as soon as the frequency difference between the two lasers is equal to a Raman-active rovibrational or rotational transition frequency. The Raman resonance can be detected in different ways: by coherent anti-Stokes Raman scattering (CARS) or the corresponding Stokes process (CSRS), by a gain in one of the beams (stimulated Raman gain spectroscopy, SRGS) or a loss in the other (inverse Raman spectroscopy, IRS), or even …
Identification for a general class of LPV Models
2000
Abstract In this paper we consider the problem of identifying discrete-time Linear Parameter Varying (LPV) models of non-linear or time-varying systems. LPV models are considered for their connection with the industrial practice of gain-scheduling. We assume that inputs, outputs and the scheduling parameters are measured, and a form of the functional dependence of the coefficients on the parameters is known. We show how the identification problem can be reduced to a linear regression so that a Least Mean Square identification algorithm can be reformulated. Conditions on the persistency of excitation in terms of the inputs and parameter trajectories are given to ensure the consistency of the…
Bone mineral metabolism in the micropremie
2000
Environmental factors, nutritional supplies, hormonal status, diseases, and treatments appear to affect postnatal skeletal growth and mineralization in VLBW infants. Compared with their term counterparts, ELBW infants are at risk of postnatal growth deficiency and osteopenia at the time of hospital discharge. From recent data, DXA is becoming one of the reference techniques to evaluate mineral status, whole-body composition, and effects of dietary manipulations on weight gain composition and mineral accretion in preterm infants. Weight gain and length increases need to be evaluated carefully during the first weeks of life, in the intensive care unit and out of it, in the step down unit. Nut…
Maternal complications in pregnancy and wheezing in early childhood: a pooled analysis of 14 birth cohorts
2015
Background: Evidence on the effect of maternal complications in pregnancy on wheezing in offspring is still insufficient. Methods: A pooled analysis was performed on individual participant data from fourteen European birth cohorts to assess the relationship between several maternal pregnancy complications and wheezing symptoms in the offspring. Exposures of interest included hypertension and preeclampsia, diabetes, as well as pre-pregnancy overweight (body mass index between 25 and 29.9) and obesity (body mass index >= 30) compared with normal weight (body mass index between 18.5 and 24.9). Outcomes included both ever and recurrent wheezing from birth up to 12-24 months of age. Cohort-speci…
Nutritional assessment in preterm infants with special reference to body composition
2001
In recent years, improvements in care have significantly improved survival in preterm and, particularily, the very low birth weight infant (VLBW). While immediate survival can be directly related to pulmonary maturity, several studies stress the importance of timely and adequate nutrition in these high-risk infants on a short- and long-term [1]. Yet, nutritional support remains a very controversial issue in these high-risk infants. Early provision of adequate intakes may be limited by clinical instability and immaturity. At the same time, nutritional requirements and methods of nutritional assessment are not well defined. The aim of this paper is to outline some of the methods used during n…
Public responses to intimate partner violence against women: the influence of perceived severity and personal responsibility.
2009
This paper explored public willingness to act when exposed to cases of intimate partner violence against women, by analyzing the influence of perceived severity and personal responsibility on two types of responses: mediating and reporting to the police. Results (N = 419) yielded main effects of personal responsibility for both types of responses. No main effects of perceived severity were found. A significant interaction between perceived severity and personal responsibility was found only for reporting responses. Results are discussed in light of the helping behavior research tradition. Implications for public education and advocacy programs are also considered. Marisol.lila@uv.es; Enriqu…
