Altitude and wind effects on long jump performance with particular reference to the world record established by Bob Beamon

An analysis of long jump performance, including both the approach and aerial phases, is applied to Bob Beamon's legendary leap at the Mexico City Olympic Games of 1968. It is shown that the combined effects of altitude and wind assistance yielded an increment in the length of the jump of about 31 cm, compared to a corresponding jump at sea level under still air conditions. The main factor is shown to be the increased sprinting speed attained under favourable conditions of wind and altitude.     

Improving the Academic Performance of Non‐native English‐Speaking Students: the Contribution of Pre‐sessional English Language Programmes

There is an established, if weak, inverse relationship between levels of English language proficiency and academic performance in higher education. In response, higher education institutions (HEIs) insist upon minimum entry requirements concerning language for international applicants. Many HEIs now also offer pre‐sessional English courses to bring applicants up to the designated language requirement. This paper revisits the research into language proficiency and academic performance using data on all full‐time students (17,925) attending a major UK HEI in the academic year 2011–2012, 4,342 of whom were non‐native English speakers. The findings confirm that while higher International English Language Testing System (IELTS) marks at entry translate into higher grade point averages (GPAs), students who undertake pre‐sessional courses do notably worse in GPA terms than students who arrive with acceptable (for the course) IELTS scores. These findings suggest HEIs (and, by extension, international students) could benefit from a review regarding the appropriateness of current pre‐sessional English language proficiency programmes.
