Increasing plantarflexion angle during landing reduces vertical ground reaction forces,loading rates and the hip’s contribution to support moment within participants

The ankle joint’s role in shock absorption during landing has been researched in many studies, which have found that landing with higher amounts of plantarflexion (PF) results in lower peak vertical ground reaction forces and loading rates. However, there has not yet been a study that compares drop landings within participants along a quantitative continuum of PF angles. Using a custom-written real-time feedback program, participants adjusted their ankles to an instructed PF angle and dropped onto two force platforms. For increasing PF, peak ground reaction force and peak loading rate during weight acceptance decreased significantly. The hip’s contribution to peak support moment decreased as PF at initial contact increased up to 30°. The ankle and knee contributions increased over this same continuum of PF angles. There appears to be no optimal PF angle based on peak ground reaction force and loading rate measurements, but there may be an optimum where joint contributions to peak support moment converge and the hip moment’s contribution is minimised.     

Social gaze in preterm infants may act as an early indicator of atypical lateralization

Visual field biases have been identified as markers of atypical lateralization in children with developmental conditions, but this is the first investigation to consider early lateralized gaze behaviors for social stimuli in preterm infants. Eye-tracking methods with 51 preterm (33 male, 92.1% White) and 61 term-born (31 male, 90.1% White) infants aged 8–10 months from Edinburgh, UK, captured the development of visual field biases, comparing gaze behavior to social and non-social stimuli on the left versus right of the screen. Preterm infants showed a significantly reduced interest to social stimuli on the left versus right compared to term children (d = .58). Preterm children exhibit early differential orienting preferences that may be an early indicator of atypical lateralized function.

Narrative inquiry and the problem of representation: ‘giving voice’, making meaning

In this article, the author argues that the exploration of alternative forms of research representation can result in new possibilities for making meaning in educational research. Narrative inquiry as a methodology has become established as an approach in education but remains contested in many ways. How we come to an understanding of such research findings and in particular how the issues of voice and representation are resolved are subject to much debate. Here, the author proposes that using fictive methods of representation of research, particularly poetry, can have implications for the ways in which meaning is made and therefore the possible meanings that can be made. Further, this article argues that the poetic form allows for the inclusion of many voices and stories in a non-hierarchical manner, making the author's influence explicit without it being dominant. Researchers have argued for poetic representations of research data as a means to evoke the participants' experience whilst making the author's influence explicit; here, it is argued that poetry can be utilized to provide a fuller representation of the research, placing the voice of the participants, the researcher and the literature on an equal level within the whole story of the research project. This article first details narrative inquiry as a methodological approach and its particular application to educational research before discussing the issues surrounding voice and representation. Subsequently, fictive forms of representation are explored as a means of addressing these issues.     

A longitudinal examination of African American adolescents' attributions about achievement outcomes

Developmental, gender, and academic domain differences in causal attributions and the influence of attributions on classroom engagement were explored longitudinally in 115 African American adolescents. In Grades 8 and 11, adolescents reported attributions for success and failure in math, English and writing, and science. In Grade 11, English and mathematics teachers rated students' classroom engagement. Boys were more likely than girls to attribute math successes to high ability and to attribute English failures to low ability. Both genders' ability attributions for math became more negative from eighth to eleventh grades. Grade 8 attributions of math failure to lack of ability were negatively related to Grade 11 math classroom engagement. Results illustrate the gendered nature of motivational beliefs among Black youth.     

Contemporary discourses in Information Systems Research: Methodological inclusiveness in a sample of Information Systems Journals

We propose a framework to reflect on the development of four information systems (IS) paradigms, arguing that this field has followed a similar path to that of Management Sciences (MS). The framework comprises four IS paradigms/discourses: (1) positivist/normative; (2) soft/interpretive; (3) critical/pluralistic; and (4) constructivist/2nd order cybernetics. The paper characterizes these approaches to IS by using four key terms: System; Organisation; Management and Information, exploring the way these concepts are perceived through the lens of the four paradigms. The paper reports on the nature of current IS trends, from an initial survey of six top IS journals identifying articles adhering to the interpretive, critical and constructivist paradigms published between 1999 and 2009. Results indicate that IS is moving towards research practice in which interpretive, critical and constructivist discourses are utilised. Implications of the proposed framework and publication trends, together with some points for further research, are offered.

Visions, Prospects and Compromises

This paper traces the way in which the physical design of the New Universities reflected the aspirations of their founders. It goes on to analyse the relationship between the architectural vision and the reality of the needs and perceptions of rapidly developing institutions.
