To define the C. elegans aging process at the molecular level, we used DNA microarray experiments to identify a set of 1294 age-regulated genes and found that the GATA transcription factors ELT-3, ELT-5, and ELT-6 are responsible for age regulation of a large fraction of these genes. Expression of elt-5 and elt-6 increases during normal aging, and both of these GATA factors repress expression o...

In this paper, I shall discuss issues regarding globalization and culture in the context of English language teaching (ELT), with a particular focus on Chinese ELT materials in secondary schools in China. Globalization has a far-reaching impact on the foreign language education industry in China. Chinese learners of English view globalization positively as opportunities for geographical and soc...

We have identified a gene encoding a new member of the Caenorhabditis elegans GATA transcription factor family, elt-3. The predicted ELT-3 polypeptide contains a single GATA-type zinc finger (C-X2-C-X17-C-X2-C) along with a conserved adjacent basic region. elt-3 mRNA is present in all stages of C. elegans development but is most abundant in embryos. Reporter gene analysis and antibody staining ...

We describe the elt-4 gene from the nematode Caenorhabditis elegans. elt-4 is predicted to encode a very small (72 residues, 8.1 kD) GATA-type zinc finger transcription factor. The elt-4 gene is located approximately 5 kb upstream of the C. elegans elt-2 gene, which also encodes a GATA-type transcription factor; the zinc finger DNA-binding domains are highly conserved (24/25 residues) between t...

the present paper seeks to investigate the cognitive abilities of expert efl teachers. to this aim, the existing literature was examined and ten cognitive themes were derived which were further investigated through interviews conducted with ten academics, teacher trainers and exemplary teachers of the field in the iranian context. the ten extracted themes were attested by interviewees’ comments...

The Caenorhabditis elegans GATA transcription factor elt-1 has previously been shown to have a central role in the specification of hypodermal (epidermal) cell fates and acts several cell divisions before the birth of hypodermal cells. Here we report that elt-1 also has essential functions during subsequent development. Reporter gene studies show that elt-1 expression is maintained in lateral s...

the concept of teacher efficacy has received significant attention in educational contexts in the recent years and has been empirically probed at 2 levels: individual teacher efficacy and collective teacher efficacy. having their origins in the social cognitive theory, teacher and collective efficacy perceptions are quite distinct constructs, each affecting educational decisions and student ach...

This study was conducted in English for Academic Purposes (EAP) context to explore Iranian teachers' perceptions of their pedagogical content knowledge (PCK) and their sense of professional identity (PI) as well as to scrutinize how their cognitions were practiced in EAP classes. To this end, two ELT teachers and two content instructors (i.e. subject experts who teach EAP courses in addition to...
