BACKGROUND Increases in portion size are thought by many to promote obesity in children. However, this relationship remains unclear. Here, we explore the extent to which a child's BMI is predicted both by parental beliefs about their child's ideal and maximum portion size and/or by the child's own beliefs. METHODS Parent-child (5-11 years) dyads (N = 217) were recruited from a randomized cont...

Background & Aims: Malnutrition is defined as nutritional disorders or unfavourable health status that can be the result of overconsumption or underconsumption of one or more nutrients. The causes of malnutrition are complex, multidimensional, and population specific. United Nations Children’s Fund (UNICEF) has adapted a conceptual framework for facilitating researchers in determining the cause...

hospitalization of child is one of the most stressful events of life for parents and children. this fear and stress may affect the process of treatment. since there is no information available about the source of distress and needs of iranian parents during the inpatient care of their children, we designed a research in order to discover the main source of worries and fears among parents. in th...

Almost all parents have preference to the number and sex of children, somebody like boy more and somebody like girl more. The ideal sex composition of children to most couples in China is to have one boy and one girl (Zheng, 2004), which was also true in China for the last two thousand years. If there were no limit to number of children, and if a couple had very strong sex preference of childre...

Introduction: Congenital anomalies of the cochlea and labyrinth can be associated with meningitis and varying degrees of hearing loss or deafness. Despite antibiotics, meningitis remains a life threatening complication.   Case Report: We report a case of recurrent meningitis following episodes of otitis media in a cochlear implantee child with bilateral vestibulocochlear malformation, due to f...

All rings in this paper are commutative with unity; we will deal mainly with integral domains. Let R be a ring with total quotient ring K. A fractional ideal I of R is invertible if II−1 = R; equivalently, I is a projective module of rank 1 (see, e.g., [Eis95, Section 11.3]). Here, I−1 = (R : I) = {x ∈ K |xI ⊆ R}. Moreover, a projective R-module of rank 1 is isomorphic to an invertible ideal. (...

Since class numbers of CM number fields of a given degree go to infinity with the absolute values of their discriminants, it is reasonable to ask whether the same conclusion still holds true for the exponents of their ideal class groups. We prove that under the assumption of the Generalized Riemann Hypothesis this is indeed the case. 1991 Mathematics Subject Classification. Primary 11R29, 11R21.
