Development and Application of Needle Trap Device

GAL4 enhancer trap patterns during Drosophila development.

To identify genes expressed in interesting spatial and temporal patterns during development, we mobilized transposons carrying the yeast transcriptional activator, GAL4, to create new insertions throughout the Drosophila genome. At these new sites, neighboring enhancers drive expression of GAL4 in a pattern similar to that of nearby genes (Brand and Perrimon, 1993). Since GAL4 binds to a UAS ta...

Asset-Liability Management and Liquidity Trap (Case Study: Credit Institute for Development)

An increase in the ability to timely meet commitments which will be due in the near future is a prerequisite for the survival of banks. Hence, the correct and optimal management of liquidity is an important affair that banks should perform. The present study aimed mainly to test the management of asset-liability and liquidity trap in the Credit Institute for Development. The research is applied...

Patterns of gene action in plant development revealed by enhancer trap and gene trap transposable elements.

The crucifer Arabidopsis thaliana has been used widely as a model organism for the study of plant development. We describe here the development of an efficient insertional mutagenesis system in Arabidopsis that permits identification of genes by their patterns of expression during development. Transposable elements of the Ac/Ds system carrying the GUS reporter gene have been designed to act as ...

The Knowledge Trap: Human Capital and Development Reconsidered∗

This paper presents a model where human capital differences, rather than technology differences, can explain several central phenomena in the world economy. The results follow from the educational choices of workers, who decide (a) how broadly and (b) how much to train, given the decisions of other workers. A "knowledge trap" occurs in economies where skilled workers favor broad but shallow kno...
