In this paper, we review experiments to characterise the developmental expression and the responses to all-trans retinoic acid (RA) of six members of the Hox-2 complex of homeobox-containing genes, during the early development of Xenopus laevis. We showed that the six genes are expressed in a spatial sequence which is colinear with their putative 3' to 5' chromosomal sequence and that five of t...

Generic competences are considered to be the ability of people adapt changes, relate others and work collaboratively. The objective this study was compare generic university students from Peru Cuba. sample consisted 248 female public universities with current enrollment in (127) Cuba (121). data collection carried out using questionnaire on (CCGEU), Cronbach's Alpha reliability value .979, show...

During vertebrate neural development, positional information is largely specified by extracellular morphogens. Their distribution, however, is very dynamic due to the multiple roles played by the same signals in the developing and adult neural tissue. This suggests that neural progenitors are able to modify their competence to respond to morphogen signalling and autonomously maintain positional...

In the Netherlands, as in many European countries, classrooms display a growing cultural diversity. There is only very limited empirically supported data on the interpersonal competence teachers need in Dutch classrooms and studies from other countries cannot be generalized because of differences in the composition of the student population. This paper reports on an exploratory study in two sch...

The main focus of this paper is the characterization of generic musical structure in terms of the apparatus of formal language theory. It is argued that musical competence falls into the same class as natural language with respect to strong generative capacity – the class of mildly context-sensitive languages described by Joshi (1985).

this study intends to propose a modern model in the field of human resources (hr) strategic management through designing human resources’ competence framework. based on this strategic orientation of organization on human resources management system has been investigated considering the mediating role of competence approach in central bank of the islamic republic of iran. in order to implement a...

Stem cells ensure tissue homeostasis through the production of differentiating and self-renewing progeny. In some tissues, this is achieved by the function of a definitive stem cell niche. However, the mechanisms that operate in mouse spermatogenesis are unknown because undifferentiated spermatogonia (Aundiff ) are motile and intermingle with differentiating cells in an ‘open’ niche environment...
