A language L is called thin if there exists an integer n0 such that for all n n0 L contains at most one word of length n. We show that thinness is decidable for exponential D0L languages. We show also that Siegel's result concerning integral points on algebraic curves of positive genus can often be used to prove that a polynomially bounded HD0L language is thin.

It is well known that a capacity C is countably subadditive, i.e. We shall prove that the reverse inequality, up to a multiplicative constant, holds for some decomposition of E , provided there is a measure comparable to C. Such a property will be referred to as quasiadditivity. As an application, we shall show that the Green energy for a uniformly-regular domain is quasiadditive with respect t...

Perfectionistic self-presentation defines the attempt at presenting the self as perfect through the public concealment of personal defects and/or through the display of attributes perceived as capable to gather positive attention of others. Although perfectionism has long been considered a central aspect of eating psychopathology mediational studies between this construct and these conditions a...

OBJECTIVE This study examined the prevalence of thinness, overweight, and obesity in Cameroon children ranging from 8 to 15 years old using several published references as evaluation tools. METHODS A stratified sample was used with eleven schools randomly selected, and data from 2689 children (52.2% girls) ranging from 8 to 15 years were analyzed. Weight and height were recorded and BMI was c...

BACKGROUND Upper-arm muscle area (UMA), upper-arm fat area (UFA), arm-fat index (AFI), upper-arm fat estimate (UFE) and upper-arm muscle estimate (UME) was introduced for the assessment of body-composition. This cross-sectional study assessed age-sex specific upper-arm composition and nutritional status among children and adolescents. METHODS The present cross-sectional study was conducted am...

PURPOSE This study investigated the agreement of four anthropometric-based measurements including weight-for-height (WH), body mass index-for-age (BMI), mid-upper arm circumference-for-age (MUAC) and triceps skinfold thickness-for-age (TST) to identify underweight and overweight children and adolescents. METHODS Two data sets were used in this research. The first one was a multistage random s...

There is limited information on the magnitude and determinants of household food insecurity (HFI) and how it relates to the nutritional status of pregnant women in Northern Ghana. The magnitude, determinants of HFI, and how it relates to the nutritional status of pregnant women were evaluated in the Africa RISING West Africa project intervention communities in Northern Ghana. The prevalence of ...

Initial research suggested that only European American women developed eating disorders (Garner, 1993), yet recent studies have shown that African American women do experience them (e.g., Lester & Petrie, 1998b; Mulholland & Mintz, 2001) and also may be negatively affected by similar sociocultural variables. In this study, we examined a sociocultural model of eating disorders for African Americ...

Objectification theory has linked self-objectification to negative emotional experiences and disordered eating behavior in cultures that sexually objectify the female body. This link has not been empirically tested in a clinical sample of women with eating disorders. In the present effort, 209 women in residential treatment for eating disorders completed self-report measures of self-objectifica...

OBJECTIVE Relationships were studied between emotional, external and restrained eating behavior, and bulimia, and also between these types of eating behavior and body dissatisfaction and drive for thinness. METHOD The sample consisted of female adolescents. Eating behavior and body evaluation were measured with scales of the Dutch Eating Behaviour Questionnaire (DEBQ) and the Eating Disorders...
