Abstract-ThisTo investigate which components of self-efficacy might have more predictive power in predicting teachers' collective efficacy, regression analysis was run. The first subscale of self-efficacy, i.e., self-efficacy for students' engagement, was found to be a good predictor of teachers' self-efficacy. The paper presents possible differences in the sources of collective efficacy and teacher self-efficacy and the interaction between teachers' self-efficacy and collective efficacy. The conclusions and implications of the research are discussed with reference to Bandura's (1977) social cognitive theory and the earlier findings.

Abstract-The present research aims at exploring the relationship between novice English teachers' knowledge and their self-efficacy. A teacher knowledge test and an efficacy questionnaire were administered to 55 novice English teachers. The data were gathered from male and female novice teachers teaching at language institutes in Tehran with ages between 20 and 25. The results showed that there is a significant relationship between English Teachers Knowledge Test (TKT) and their self-efficacy. The results are discussed in the light of previous findings.

Background: In treatment of advanced non-small cell lung cancer, the effect of chemotherapy is limited and unpredictable. Especially in cases of recurrent or relapsed tumor, the choice of regimen is very restricted. This study was to determine whether the sensitivity test of chemotherapeutic agents is valuable in choosing the drugs of the second-line or third-line treatment in the advanced non-small cell lung cancer. Methods: In 11 patients, resistant to or relapsed after the first-line or second-line chemotherapy, we got the tumor cells by the nine neck nodes or two bronchoscopic biopsies and did chemosensitivity test by the adenosine triphosphate-based chemotherapy response assay methods. The drugs tested were cisplatin, carboplatin, paclitaxel, docetaxel, gemcitabine, vinorelbine and irinotecan. We regarded the drug is sensitive in cases the cell death rate was above 30%, and chose two drugs of higher cell death rates as chemotherapeutic agents. After two cycles of chemotherapy, the response was evaluated. Results:The mean age of the patients was 54.9 year, and one patient was excluded in the final analysis because the secondary tumor was proved as small cell lung cancer. Five patients were for the second-line and another five were for the third-line chemotherapy. Six tumors were sensitive to 3 drugs, 2 tumors were to two, and another two were to one agent. Cisplatin, gemcitabine, vinorelbine and irinotecan were sensitive in 5 cases respectively. Docetaxel was sensitive in 3 cases, paclitaxel and carboplatin were sensitive in 2 cases respectively. Regardless of the previous treatment, cisplatin kept the sensitivity in 4 of 8, gemcitabine in 2 of 3, and docetaxel in 1 of 3 cases. Complete response was found in 2 of 8 evaluable patients, and partial response was in 3, stable in 1, and disease progressed in 2 cases. Conclusions: In cases of recurrent or resistant non-small cell lung cancer, chemosensitivity test would provide another options in choosing the chemotherapeutic agents.
