This paper explores the correlations that exist between standardized test scores in seven subjects and sociodemographic variables for ninth-graders in two Mexican states. The analysis is performed with two basic sets of variables: identity or circumstances, which cannot change easily such as language spoken at home, and behavior variables like working outside the household. Additionally, we con...

The present study describes approaches for the identification of individual beech trees using maternal tissues from their seeds or fruits. Four microsatellite markers were used for genetic analysis of seedlots from Fagus orientalis Lipsky, a highly out-crossing tree species. Seeds from 11 single-tree harvests belonging to one population, (7 seeds from each), as well as non-paranchymatic materna...

Henderson described a method to reduce the number of mixed-model equations when estimating additive and nonadditive genetic variances or predicting additive and nonadditive genetic merits. The extension to a maternal effects model is straight-forward. When maternal genetic effects are strictly additive, an algebraic identity was found that reduces by a factor of two the order of a matrix that m...

In the context of the trend toward delayed parenthood, this study examines whether older maternal age is associated with greater psychological maturity and whether greater psychological maturity provides any adaptive benefit during the transition to motherhood. A sample of 240 predominantly English-speaking Australian women in a metropolitan area expecting their 1st baby (mean age = 32.81 years...

BACKGROUND Maternal role adaptation involves conceptualization and establishment of a responsible maternal role, which is characterized by a new identity and formation of mothering behaviors. Becoming a mother in intensive care unit is very different from becoming a mother with a term infant at home. The aim of the study was to develop a valid and reliable tool for assessment of maternal role a...

PURPOSE The purpose of the study was to identify and explain the essences and structures of maternal conflicts in Vietnamese married immigrant women in Korea. METHODS A phenomenological methodology was used for the study. Eleven Vietnamese married immigrant women participated in the study. Verbatim transcripts were analyzed using Colaizzi's method. RESULTS Four categories, 10 clusters and 2...

background: improving maternal health is one of the eight millennium development goals (mdgs) aimed at improving maternal healthcare and reducing maternal mortality. the utilization of maternal health services is influenced by several factors that need to be better understood. the objective of this study was to estimate the role of socio-economic position as a determinant of the utilization of ...
