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.     

English Language Learners and Learning Disabilities: Research Agenda and Implications for Practice

Although little is known about learning disabilities (LDs) in English language learners (ELLs), there is a substantial knowledge base about the identification, assessment, and intervention of and for LDs in monolingual native English‐speaking students. Building on this knowledge, participants at an October 2003 National Symposium on Learning Disabilities in English Language Learners were asked to suggest research questions, priorities, and suggestions on how to build the necessary infrastructure to address critical research needs. In the discussions that took place, important themes emerged: (1) identification and assessment of LD and/or reading disabilities (RD) in ELLs (ELL/Ds), (2) understanding of the language and literacy developmental trajectories of ELLs, (3) understanding of the individual and contextual factors affecting outcomes, (4) the intersection of all of these areas with neurobiology, and (5) developing and testing the effectiveness of interventions for learning disabilities in ELL/Ds. These themes, and the research agenda that was forged around them, are presented. In addition, the practice implications of this agenda are presented, along with some suggestions for current practice while we await future research findings.     

Family‐centred practice: collaboration,competency and evidence

In the 1990s, the developing field of early intervention with young children with disabilities and their families adopted family‐centred practice as its philosophical foundation. Family‐centred practice includes three key elements: (1) an emphasis on strengths, not deficits; (2) promoting family choice and control over desired resources; and (3) the development of a collaborative relationship between parents and professionals. During the last two decades, the field of early childhood disability has successfully defined the working principles of family‐centred practice for practitioners. Although research has acknowledged that the paradigm shift to family‐centred practice is neither simple nor easy, a substantive body of evidence demonstrates that (a) family‐centred practice can be linked to a wide range of demonstrated benefits for both children and families, and (b) families are more satisfied and find family‐centred practice to be more helpful than other models of practice.     

Helping the One You Hurt: Toddlers’ Rudimentary Guilt,Shame, and Prosocial Behavior After Harming Another

This study explored the role of guilt and shame in early prosocial behavior by extending previous findings that guilt‐ and shame‐like responses can be distinguished in toddlers and, for the first time, examining their associations with helping. Toddlers (n = 32; M_age = 28.9 months) were led to believe they broke an adult's toy, after which they exhibited either a guilt‐like response that included frequently confessing their behavior and trying to repair the toy; or a shame‐like response that included frequently avoiding the adult and seldom confessing or attempting to repair the toy. In subsequent prosocial tasks, children showing a guilt‐like response helped an adult in emotional distress significantly faster and more frequently than did children showing a shame‐like response.
