Intuitive eating: A novel eating style? Evidence from a Spanish sample
2020
Contains fulltext : 217000.pdf (Publisher’s version ) (Closed access) Intuitive eating is defined as an adaptive way of eating that maintains a strong connection with the internal physiological signs of hunger and satiety. It has four elements: unconditional permission to eat whenever and whatever food is desired, eating for physical rather than for emotional reasons, reliance on hunger and satiety cues to determine when and how much to eat, and body-food choice congruence. In this study, we assessed the differences and similarities between intuitive eating, as measured with the Intuitive Eating Scale-2, and eating styles (restrained, emotional, and external eating), as assessed with the Du…
Influence of the concentration of oxygen on the swimming path of Brachionus plicatilis (Rotifera)
1993
Brachionus plicatilis females were maintained for > 24 hours in water where the concentration of oxygen was precisely controlled (spherical flasks with ≥ 6 mg 1−1 or < 0.5 mg 1−1; food = dead Tetraselmis sp.). Each female was randomly taken from one flask and quickly placed in an observation chamber containing the same experimental conditions. The swimming path was videotaped (5 minutes); then the size of the female was measured. The tape was analyzed by automatic tracking (25 x, y coordinates of the center of the animal, in a 512 × 512 pixels space). The swimming path was analyzed for ~45 females in both treatments. The speed (mm s−1 body length−1) was calculated for all trajectories, or o…
Maternal literacy teaching, causal attributions and children’s literacy skills in Finnish-speaking and language minority families
2016
Abstract This study investigated the effect of mothers’ (language minority group mothers, LM, n = 49, and Finnish speaking mothers, MP, n = 368) literacy teaching at home, and mothers’ causal attributions of their children’s (mean age 11.48 years) literacy skills at fourth grade in Finland. For Finnish speaking mothers, results showed a negative correlation between the amount of literacy taught at home and children’s performance on reading tests i.e., more teaching was associated with poorer performance and vice versa. Also, the more MP mothers measured their children’s success by their ability, the better their children performed in reading comprehension tests. In the LM group, maternal li…
The Stabilizing Role of Government Size
2007
This paper presents an analysis of how alternative models of the business cycle can replicate the stylized fact that large governments are associated with less volatile economies. Our analysis shows that adding nominal rigidities and costs of capital adjustment to an otherwise standard RBC model can generate a negative correlation between government size and the volatility of output. However, in the model, we find that the stabilizing effect is only due to a composition effect and it is not present when we look at the volatility of private output. Given that empirically we also observe a negative correlation between government size and the volatility of consumption, we modify the model by i…
The decision process in forward-masked intensity discrimination: evidence from molecular analyses.
2009
In a two-interval forced-choice intensity discrimination task presenting a fixed increment, the level of the forward masker in interval 1 and interval 2 was sampled independently from the same normal distribution on each trial. Mean and standard deviation of the distribution were varied. Correlational analyses of the trial-by-trial data revealed different decision strategies depending on the relation between mean masker level and standard level. If the two levels were identical, listeners tended to select the interval containing the higher-level masker, behaving like an energy detector at the output of a temporal window of integration. For mean masker level higher than the standard level, m…
Bone mineral density in relation to anthropometric properties, physical activity and smoking in 75-year-old men and women
1993
Bone mineral content (BMC, gem−2) and density (BMD, gem−3) were studied in 75-year-old men and women in relation to anthropometric and certain life-style factors. This study covered all the men and women born in 1914 who were residents in the city of Jyvaskyla in 1989 (N=388). A hundred and three men and 188 women participated in bone measurements performed at the calcaneus using a 125I-photon absorption method. BMC was on average 36% and BMD 17% higher in the men than in the women. BMC and BMD associated with body mass in both sexes, and with body fat and use of estrogen in the women. There was a negative correlation between the BMD values and the number of cigarettes smoked over the entir…
The calculation of shadow prices for industrial wastes using distance functions: An analysis for Spanish ceramic pavements firms
2001
Abstract This paper deals with the calculation of shadow prices for two industrial wastes generated on their production processes by 18 firms belonging to the Spanish ceramic pavements industry. These prices are then used to calculate an extended productivity index which takes into consideration wastes going with the production of marketable goods. We follow the methodological approach first proposed by Fare et al. (The Review of Economics and Statistics 75 (1993)). A negative correlation is found between absolute shadow prices and wastes production intensity, reflecting a greater marginal cost of eliminating wastes for those firms using less contaminant production processes. Differences be…
Intensity output and effectiveness of light curing units in dental offices
2018
Background The aims of the study were measuring the light intensity of light curing units used in Qazvin's dental offices, determining the relationship between the clinical age of these units and their light intensity, and identifying the reasons for repairing them. Material and Methods In this cross-sectional study, the output intensity of 95 light curing devices was evaluated using a radiometer. The average output intensity was divided up into four categories (less than 200, 200-299, 300-500, and more than 500 mW/cm2). In addition, a questionnaire was designed to obtain information mainly about the type, clinical age, and frequency of maintenance of the units and the reasons for fixing th…
Early Signs of Mathematics Anxiety?
2012
Abstract Mathematics anxiety refers to individual's negative affect when engaging in numerical and mathematical tasks. Researchers have recently connected high math anxiety to lower performance on math tasks, developmental dyscalculia, and lower self-efficacy towards math learning. Math anxiety scales have been made and validated mainly for secondary school and high school students. In our paper we are looking for early signs of math anxiety using a Pictorial Test (37 pictures) which we have developed for 6 to 8 year old children. Children were asked to concentrate on one picture at a time and to write down spontaneously their emotional and mathematical ideas. Most powerful sources of sadne…
982 Maternal Age, History of Migration and Incidence of Infantile Hypertrophic Pyloric Stenosis in Germany in 2000-2008
2012
Background The incidence of infantile hypertrophic pyloric stenosis (IHPS) is highly variable over time and geographic regions. A decline in IHPS incidence was recently reported in Sweden, the US, Denmark, and Scotland and in Germany. Aim In further evaluation of our previous epidemiological data, we collected data on maternal age and history of migration in mothers from the regional administrations. We examined correlations between these factors and IHPS incidence. Methods Data were extracted from the public report of Health (Gesundheitsberichterstattung des Bundes) and population data from federal state governments. We collected the numbers of IHPS (International Statistical Classificatio…
