current studies in second language (l2) learning have revealed the positive role of corrective feedback (cf) in both oral and written forms in different language features. the present study was an attempt to investigate the effect of both direct and indirect written corrective feedback (wcf) on the use of grammatical collocations in l2 writing. the study also sought to examine whether the effec...
recent years have witnessed an increased attention to form focused instruction and consciousness raising activities (ellis, 2002; doughty & williams, 1998) on the one hand and extensive and meaningful exposure to the target language (klapper & rees, 2003; day & bamford, 1998) on the other. due to significance attributed to above mentioned issues by scholars, this study attempted to bridge them ...
This study investigated the contrast ratio and grain size depending on sintering parameters of twelve different zirconia materials and compared with glass-ceramic (N=156, n=12 per group). Contrast ratio of all ceramics was measured using a spectrophotometer according to ISO 2471: 2008. Grain sizes of zirconia were determined by SEM. Data was analyzed using one-way ANOVA followed by post-hoc Sch...
Mobile banking (m-banking) faces various types of resistance that may hinder customers’ adoption in Egypt. This study identifies three groups of m-banking non-adopters, namely postponers, opponents and rejectors. The objective of the study is to explore the reasons for resisting m-banking services in Egypt and whether it differs with regards to these customer groups. Accordingly, a questionnair...
We generated exact probability distributions for sample sizes up to 35 in each of three groups ( 105 N ) and up to 10 in each of four groups ( 40 N ). We provided a portion of these exact probability tables and compared the exact distributions to the chi-square, gamma, and beta approximations. The beta approximation was best in terms of the root mean squared error. At specific significance ...
This study was performed to determine risk factors associated with osteoporosis that develops after renal transplantation. Sixty-five kidney graft recipients were included in this study. They were divided into four groups according to the time since transplantation: Group 1 (< 1 year; n = 26), group 2 (1-3 years; n = 16), group 3 (3-5 years; n = 12) and group 4 (> 5 years; n = 11). These groups...
The purpose was to compare the effects of two practicum types (off campus and on campus) on physical education teacher education (PETE) students' attitudes and perceived competence toward teaching school-aged students with physical disabilities or moderate-severe mental retardation. PETE students, enrolled in a 15-week introductory adapted physical education (APE) course and involved in eight s...
PURPOSE To assess the role of preserved bovine parietal peritoneum as a material for hernia repair in a rat ventral hernia model. METHODS An abdominal wall defect (15mm x 25mm) was created in Wistar male rats (n=40). Control animals (n=20) had the polypropylene (PP) mesh sutured into the defect, whereas bovine preserved peritoneum (BPP) was used in experimental group (n=20). After 7 and 28 da...
