A numerical property of Hilbert functions and lex segment ideals
2017
We introduce the fractal expansions, sequences of integers associated to a number. We show that these sequences characterize the Osequences and encode some information about lex segment ideals. Moreover, we introduce numerical functions called fractal functions, and we use them to solve the open problem of the classification of the Hilbert functions of any bigraded algebra.
Łojasiewicz exponents, the integral closure of ideals and Newton polyhedra
2003
We give an upper estimate for the Łojasiewicz exponent $\ell(J,I)$ of an ideal $J\subseteq A(K^{n})$ with respect to another ideal I in the ring $A(K^{n})$ of germs analytic functions $f$ : $(K^{n},\mathrm{O})\rightarrow K$ , where $K=C$ or $R$ , using Newton polyhedrons. In particular, we give a method to estimate the Łojasiewicz exponent $\alpha_{0}(f)$ of a germ $f\in A(K^{n})$ that can be applied when $f$ is Newton degenerate with respect to its Newton polyhedron.

La música tiene la capacidad de transmitir conocimientos, habilidades y valores intrínsecos a la cultura del compositor, y al mismo tiempo transmite emociones y sentimientos comunes a todas las culturas; por ello puede decirse que la música es un instrumento idóneo para el establecimiento de un diálogo intercultural. La acción comunicativa musical siempre ha sido objeto de análisis; aunque ha sido la falta de diálogo cultural la que ha aumentado la consideración de que la música puede posibilitar el camino hacia la adquisición de la Interculturalidad. Este artículo muestra cómo la música favorece el proceso comunicativo intercultural, al considerarse como la principal herramienta de trabajo…
Disentangling relations between the desirability of the thin-ideal, body checking, and worry on college women's weight-loss dieting
2019
The study used self-regulation theory to elucidate the relationships between the desirability of the thin-ideal goal, dispositional worry, body checking and weight-loss dieting (WLD) in college women. We hypothesized that body checking would mediate the relationship between the desirability of the thin-ideal goal and WLD: the desire to be thin would be associated with more WLD through more frequent body checking. We also hypothesized that dispositional worry would moderate this mediation pathway, such that the mediation pathway would be stronger for those higher in worry. Finally, all effects were expected to occur when controlling for self-reported body size. A paper and pencil survey was …
Food intake affects state body image: Impact of restrained eating patterns and concerns about eating, weight and shape
2006
Body image disturbances play a significant role in the development of eating disorders. Since body image can vary in diverse contexts, the aim of the present experiment was to investigate whether it is affected by recent food intake. Fifty-seven females without clinically relevant eating disorders were randomly assigned to an experimental group (EG, n=28) that consumed a milkshake while watching a neutral film and a control group (CG, n=29) that only viewed the movie. Before and after the tasks, participants filled in the "Body Image States Scale" and the "Mood Questionnaire" and indicated their own "actual", "felt" and "ideal" body dimensions with a digital distortion technique based on a …
Psychometric properties of measures of sociocultural influence and internalization of appearance ideals across eight countries
2020
The aim of the current study was to examine the psychometric properties of two well-established measures of sociocultural influence and internalization of the thin/low body fat ideal and muscular ideal. Data from 6272 emerging adults (68.9 % female), aged 18-30 years from Australia, Belgium, Canada, China, Italy, Japan, Spain, and the U.S. were included in this study. Participants completed measures of pressure from mother, fathers, peers, and media, to both increase muscles and lose weight, as well as internalization of the thin/low body fat ideal and muscular ideal. Overall, support for partial invariance was found across the scales. In addition, group level differences were found between…
Preference for attractiveness and thinness in a partner: Influence of internalization of the thin ideal and shape/weight dissatisfaction in heterosex…
2009
This study assesses whether characteristics of one's own body image influences preferences of attractiveness in a partner. The role of gender and sexual orientation is also considered. Heterosexual women (n=67), lesbian women (n=73), heterosexual men (n=61) and gay men (n=82) participated in an internet survey assessing attitudes towards the body and preferences of attractiveness in a partner. Men in particular were found to prefer attractive partners, regardless of sexual orientation. Weight/shape dissatisfaction was found to be a negative predictor for heterosexual men and women. For gay men, preferences were better explained by internalization and weight/shape dissatisfaction. No such as…
An improved method for evaluating ideal standards in self-perception and mate preferences
2014
The aim of the study was to improve the methodology for measuring ideals of self-perception and mate preferences. The Ideal Standards Model (ISM; Fletcher, Simpson, Thomas & Giles, 1999) was used as a basis for development of the scale. It was further modified by adding a number of items from previous studies. Data were collected from 223 participants, aged 19 to 27 years. The results suggested that a modified five-factor version of the ISM is an appropriate method for evaluation of ideal characteristics. The five factors are warmth/ trustworthiness, status/ resources, intelligence, social skills and physical attractiveness.
The impact of exposure to images of ideally thin models in TV commercials on eating behavior: an experimental study with women diagnosed with bulimia…
2011
This study investigates whether eating behavior in women with diagnosed bulimia nervosa is influenced by prior exposure to images of ideally thin models. Twenty-six participants diagnosed with bulimia nervosa (BN) and 30 normal controls (NC) were exposed to body-related and neutral TV commercials; then food that typically triggers binge eating was provided, and the amount of food eaten was measured. No significant difference for food intake between NC and BN could be found, but food intake for BN was predicted by the degree of thoughts related to eating behaviors during exposure to the thin ideal. No impact of general body image or eating pathology on food intake could be found. The results…
