Quasi-static mechanical behaviour of soils used for natural turf sports surfaces and stud force prediction

The quasi-static testing of soils used in natural turf pitches yields key parameters in soil modelling, including elastic moduli, Poisson’s ratio and Mohr–Coulomb parameters for shearing resistance and cohesion in soil. The bulk strength of a Sand soil used in the construction of elite sports surfaces was found to increase initially and then decrease with increasing water content due to apparent cohesion effects. For a Clay Loam soil, more common in recreational facilities, shear strength decreased with water content. Reducing density resulted in a reduction of shear strength and elastic moduli in both soils due to reduced packing of particles reducing particle–particle contact surface area. The effect of roots on the shear strength of a Sand soil was not significant but reduced elastic moduli significantly. Horizontal forces measured during running and turning in a biomechanics laboratory were in good agreement with forces predicted using a simple quasi-static soil model for coarse-grained (Sand) soils although this was not the case with the Clay Loam soil.     

Observed characteristics and teacher quality: Impacts of sample selection on a value added model

We measure the impact of observed teacher characteristics on student math and reading proficiency using a rich dataset from Florida. We expand upon prior work by accounting directly for nonrandom attrition of teachers from the classroom in a sample selection framework. We find evidence that sample selection is present in the estimation of the influence of teacher characteristics, but that failure to account for it does not appear to substantially bias estimation. Further, our procedure produces some evidence that more effective teachers are more likely to exit the classroom.     

Human perceptions of artificial surfaces for field hockey

Measuring the performance of a sports surface is typically derived from a series of field and laboratory tests that assess the playing properties under simulated game conditions. However, from a player’s perspective their own comfort and confidence in the surface and its playing characteristics are equally if not more important. To date no comparative study to measure playing preference tests has been made. The aim of this research was to develop a suitable method for eliciting player perceptions of field hockey pitches and determine the key themes that players consider when assessing field hockey pitches. To elicit meaningful unbiased human perceptions of a playing surface, an individual subjective analysis was carried out, using interviews and inductive analysis of the recorded player statements. A qualitative analysis of elite hockey players (n = 22) was performed to obtain their perceptions immediately after a competitive match. The significant surface characteristics that emerged as part of an inductive analysis of their responses were grouped together and formed five general themes or dimensions: player performance, playing environment, pitch properties, ball interaction and player interaction. Each dimension was formed from a hierarchy of sub-themes. During the analysis, relationships between the dimensions were identified and a structured relationship model was produced to highlight each relationship. Players’ responses suggested that they perceived differences between pitches and that the majority of players considered a ‘hard’ pitch with a ‘low’ ball bounce facilitating a ‘fast’ game speed was desirable. However, further research is required to understand the relative importance of each theme and to develop appropriate measurement strategies to quantify the relevant engineering properties of pitch materials.     

Show Racism The Red Card: potential barriers to the effective implementation of the anti-racist message

This discussion paper focuses on anti-racist groups associated with British Association football (soccer) and the barriers that they face in relation to effective implementation of the anti-racism message and aspirational cultural change. In order to address those issues (above) this essay draws on the educational charity Show Racism the Red Card (SRTRC) and their work to educate individuals in Great Britain though football. It takes an overview of the work of the charity, specifically focusing on three key areas relating to the group’s mission statement. Concluding comments are made on the current position of SRTRC in light of recent high-profile racist incidents.     

Changing the Library Brand: A Case Study

ABSTRACT

This article outlines some of the opportunities and challenges of changing what the library “brand” means to academic and professional services staff in the rapidly changing environment of UK higher education, taking the University of Leicester as a case study. It makes a practitioner contribution to the growing body of evidence of how libraries are extending their role and how their customers are responding. It begins by considering the drivers for change in the higher education and scholarly information environments and how these are influencing the development of library services at the University of Leicester. The topics considered include researcher development, Digital Humanities, Open Access, independent learning, and curating the university's own information assets. The impact of these developments is outlined and how an evolving approach to strategic marketing is beginning to change perceptions as the boundaries of the library's role extend.     

The relationship between phonological awareness and the development of orthographic representations

A training study was conducted to investigatethe relationship between phoneme segmentationability and the development of orthographicrepresentations. Five-year-old children withvarying degrees of phoneme segmentationability were taught to read ten new words byrepeated presentation of the words onflashcards. It was found that those childrenwho were most well equipped to perform phonemesegmentation tasks acquired this new readingvocabulary significantly faster than those whowere less phonemically aware. A series ofpost-tests was implemented to discover thenature of the internal orthographicrepresentations which the children had createdfor the words learned. The results of thesepost-tests demonstrated that the children whowere most phonemically aware had alsointernalised the most detailed orthographicrepresentations, despite needing fewerlearning trials. Salient letters fororthographic storage were predictable from thechildren's phoneme segmentation abilities. This paper provides strong support for thethesis that phonemic awareness is related toorthographic storage as well as alphabeticreading techniques.     

School experiences of transgender and gender diverse students in Australia

Over the last decade, there has been an increase in global and local policy protections on the basis of gender identity and expression in education and a recent spate of coverage of transgender students on Australian television and news media. This paper explores the school experiences of Australian transgender and gender diverse students', with particular consideration of recognition of their gender identity in documentation, experiences of puberty and sexuality education, treatment by staff and students, and other forms of provision. It reports on the findings of a 2013 study which combined a survey of 189 transgender and gender diverse Australian students aged 14–25 years, with 16 online interviews with members of this group. The study was informed by a community advisory group which included a range of transgender, gender diverse and intersex people. Findings include both quantitative and qualitative data, detailing a trend towards more disruptive, fluid and inconsistent identifications by members of this student group, and a diversification of their needs at school. Student advocacy on topics including sexuality and puberty education was shown to be common and also useful in improving individual well-being and social outcomes. We offer some reflections towards more useful school practices and future research.
