TL;DR: It appears that antibiotics that interfere with DNA and RNA syntheses, such as garlic does, could constitute an effective partner in the synergic effect of garlic currently being investigated worldwide.
Abstract: Antimicrobial sensitivity tests were carried out on Escherichia coli, Shigella sp, Sal- monella sp, and Proteus mirabilis using standard procedures. Significant differences (p<0.01) were seen in the effect of the antimicrobial agents (garlic, ciprofloxacin and ampicillin), and in the sensitivities of the microbial species (p<0.01) to the antimicrobial agents were observed. The gram-negative diarrheagenic pathogens from the stool samples were highly sensitive to garlic, while ciprofloxacin (CPX) was most effective against E. coli. The differences were in- ferred to result from genetic differences among the organisms and differences in the modes of action of the antibiotics. No isolates were resistant to garlic, making it a promising antimicro- bial agent. It appears that antibiotics that interfere with DNA and RNA syntheses, such as garlic does, could constitute an effective partner in the synergic effect of garlic currently being investigated worldwide.

Abstract: Assessment is very important in the learning and instructional processes. Equally important is the use to which assessment results are put. Use of student achievement scores (SAS) as a basis for assessing the teacher's instructional compet ence or effectiveness is one of the controversial approaches to teacher evaluation. This paper examined the issues characterizing th e use of SAS as a basis of teacher assessment, and presents research results from Nigeria and abroad on the attitude of teachers to t his approach of assessing teachers. The research findings from abroad were extracted from the literature. The research in Nigeria sampled 480 secondary school teachers in Akwa Ibom State using stratified random sampling technique. The instrument for data collection was a questionnaire with a reliability estimate of .94. Three hypotheses were tested. The results showed that second ary school teachers displayed a significantly negative attitude to this teacher assessment approach; that this attitude was not sig nificantly influenced by the professional status of the teachers; and that this attitude, when the purpose of teacher assessment is summat ive, is significantly more negative than the attitude when the purpose of teacher assessment is formative. It was concluded that Nig erian teachers are not different from their counterparts abroad in their showing disdain or condemnation to the use of student achiev ement scores as indicators of teacher's competence, performance or effectiveness. Therefore, great care is required in the use of ass essment results in our schools, especially in attempts to blame teachers for poor academic performance of learners.

TL;DR: Result of data analysis, using path analyses procedures indicated that only three socio-cultural factors were effective in explaining adolescents' response to HIV/AIDS preventive practices.
Abstract: This study is a path modeling which examines the effect and magnitude of four socio-cultural indicators on adolescents response to HIV/AIDS preventive practices in Nigerian setting. Questionnaire data were generated from 316 fifth year students in 12 secondary schools in Cross River State Nigeria. Result of data analysis using path analyses procedures indicated that only three socio-cultural factors were effective in explaining adolescents response to HIV/AIDS preventive practices. Cultural indicators and sexuality attitudes had the most significant influence on adolescents response to HIV/AIDS preventive practices. In all 56.5% of the total effect of the variables was direct while 43.5% was indirect. The implications of the research findings are addressed. (authors)
