In this paper we present a phenomenographic analysis of computerscience instructors' perceptions of student success. The factors instructors believe influence student success fell into five categories which were related to: 1) the subject being taught, 2) intrinsic characteristics of the student, 3) student background, 4) student attitudes and behaviour and 5) instructor influence on student development. These categories provide insights not only into how instructors perceive students, but also how they perceive their own roles in the learning process. We found significant overlap between these qualitative results, obtained through analysis of semi-structured interviews, and the vast body of quantitative research on factors predicting student success. Studying faculty rather than students provides an alternative way to examine these questions, and using qualitative methods may provide a richer understanding of student success factors.

The recent video coding standard H.264/AVC show extremely higher coding efficiency compare to any other previous standards. Although H.264/AVC can achieve over 50 % of bit rate saving with same quality using the rate-distortion process, but it brings high computational complexity. In this paper, we propose an algorithm that can reduce the complexity of the codec by reducing the block mode decision process adaptively. In this paper an efficient method is proposed to reduce the inter mode decision coding complexity using the direct prediction methods based on inter block correlation and adaptive rate distortion cost threshold for early stopping. The intra mode decision complexity is also reduced using the early intra skip method. The experimental results show that the proposed algorithm can achieve up to 43.85-74.12% speed up ratio with a little PSNR loss. Increment in bit requirement is also not much noticeable.
