Evidence in support of the call to ban the tackle and harmful contact in school rugby: a response to World Rugby
In a paper published in BJSM (June 2016), World Rugby employees Ross Tucker and Martin Raftery and a third coauthor Evert Verhagen took issue with the recent call to ban tackling in school rugby in the UK and Ireland. That call (to ban tackling) was supported by a systematic review published in BJSM. Tucker et al claim that: (1) the mechanisms and risk factors for injury along with the incidence and severity of injury in youth rugby union have not been thoroughly identified or understood; (2) rugby players are at no greater risk of injury than other sports people, (3) this is particularly the case for children under 15 years and (4) removing the opportunity to learn the tackle from school pupils might increase rates of injuries. They conclude that a ban âmay be unnecessary and may also lead to unintended consequences such as an increase in the risk of injury later in participation.â Here we aim to rebut the case by Tucker et al. We share new research that extends the findings of our original systematic review and meta-analysis. A cautionary approach requires the removal of the tackle from school rugby as the quickest and most effective method of reducing high injury rates in youth rugby, a public health priority
The incidence of scarring on the dorsum of the hand
When undertaking image comparison of the hand between accused and perpetrator, it is not unusual for scars to be identified on the back of the hand. To investigate the occurrence of scarring in a discreet sample, a database of 238 individuals was examined, and the dorsum of the right and left hands was gridded for each individual. The position, size and type of scar were recorded within each grid. It was found that, in general, males exhibited a higher incidence of scarring than females. However, males were more likely to show scarring on their left hand whereas females were more likely to exhibit scarring on their right hand. Contrary to the literature, scarring was not most prevalent along the borders of the hand but occurred more frequently in association with the index and middle finger corridor regions. Surgical scars were rare as were large scars whereas linear scars smaller than 6 mm were the most frequently identified. Close to half of the sample did not exhibit scarring on one hand. The importance of understanding the pattern of scarring on the back of the hand is discussed in the light of forensic image comparison analysis

Using the Ages and Stages Questionnaire to teach medical students developmental assessment: a descriptive analysis
BACKGROUND: After a survey of medical graduates' skills found a lack of confidence in developmental assessment, a program was introduced with the broad aims of increasing medical student confidence and respect for the parents' role in childhood developmental assessment. Research has shown that parents' concerns are as accurate as quality screening tests in assessing development, so the program utilised the Ages and Stages Questionnaire, a parent completed, child development assessment tool. METHOD: To evaluate the program, an interpretative analysis was completed on the students' reports written during the program and a questionnaire was administered to the parents to gain their perception of the experience. As well, student confidence levels in assessing growth and development were measured at the end of the paediatric term. RESULTS: Although there was an increase in student confidence in developmental assessment at the end of the term, it was not statistically significant. However the findings indicated that students gained increased understanding of the process and enhanced recognition of the parental role, and the study suggested there was increased confidence in some students. Parents indicated that they thought they should be involved in the teaching of students. CONCLUSION: The ASQ was shown to have been useful in an education program at the level of advanced beginners in developmental assessment
The private life of echidnas: Using accelerometry and GPS to examine field biomechanics and assess the ecological impact of a widespread, semi-fossorial monotreme
The short-beaked echidna (Tachyglossus aculeatus) is a monotreme and therefore provides a unique combination of phylogenetic history, morphological differentiation and ecological specialisation for a mammal. The echidna has a unique appendicular skeleton, a highly specialised myrmecophagous lifestyle and a mode of locomotion that is neither typically mammalian nor reptilian, but has aspects of both lineages. We therefore were interested in the interactions of locomotor biomechanics, ecology and movements for wild, free-living short-beaked echidnas. To assess locomotion in its complex natural environment, we attached both GPS and accelerometer loggers to the back of echidnas in both spring and summer. We found that the locomotor biomechanics of echidnas is unique, with lower stride length and stride frequency than reported for similar-sized mammals. Speed modulation is primarily accomplished through changes in stride frequency, with a mean of 1.39 Hz and a maximum of 2.31 Hz. Daily activity period was linked to ambient air temperature, which restricted daytime activity during the hotter summer months. Echidnas had longer activity periods and longer digging bouts in spring compared with summer. In summer, echidnas had higher walking speeds than in spring, perhaps because of the shorter time suitable for activity. Echidnas spent, on average, 12% of their time digging, which indicates their potential to excavate up to 204 m3 of soil a year. This information highlights the important contribution towards ecosystem health, via bioturbation, of this widespread Australian monotreme

Creative and productive workplaces: a review
The built environment affects our well-being and this in turn influences our effectiveness in the workplace. Poor environments contribute to absenteeism and to people not working as well as they might. This is an enormous cost to the nation. High-quality environmental design is an investment, as occupants are healthier, staff-retention rates are higher, productivity is higher and sustainability ideals are more likely to be met. Workplaces reflect the culture of companies and are places that are not just functional and convenient but give the occupant a wholesome experience in terms of body and spirit
Towards A Responsible Entrepreneurship Education and the Future of the Workforce
Highlights
⢠PRME provides a Compass for universities to embed responsible education.
⢠Limited information is available on the stream of African Entrepreneurship education.
⢠Many universities are ill-equipped to develop adequate skills required for the modern job market.
⢠This study is based on the Curricular, Co-curricular and Extra-curricular Learning Pipeline Model.
Abstract
This article explores how entrepreneurship education (EE) could be adopted towards improving graduateâs skills and preparing the future workforce. It adopts interviews with 30 experienced higher education academics, executives of employment and work placement agencies in Nigeria that reveals substantial benefits of adopting entrepreneurial pedagogics, critical thinking and problem-based learning (PBL). The critical question is how can EE practices be utilised in higher education to improve future workforce? Linked to the UN Principles of Responsible Management Education (PRME), this study is based on the model of curricular, co-curricular and extra-curricular learning pipeline that focuses on âlearning in the curriculumâ and âlearning beyond the curriculumâ. The model somehow links to the six domains that formed our analytical model â knowledge and cognitive learning, innovation in teaching pedagogy, change in thinking, change in attitudes, social learning and change in action

Progress in observing and modelling the urban boundary layer
The urban boundary layer (UBL) is the part of the atmosphere in which most of the planetâs population now lives, and is one of the most complex and least understood microclimates. Given potential climate change impacts and the requirement to develop cities sustainably, the need for sound modelling and observational tools becomes pressing. This review paper considers progress made in studies of the UBL in terms of a conceptual framework spanning microscale to mesoscale determinants of UBL structure and evolution. Considerable progress in observing and modelling the urban surface energy balance has been made. The urban roughness sub-layer is an important region requiring attention as assumptions about atmospheric turbulence break down in this layer and it may dominate coupling of the surface to the UBL due to its considerable depth. The upper 90% of the UBL (mixed and residual layers) remains under-researched but new remote sensing methods and high resolution modelling tools now permit rapid progress. Surface heterogeneity dominates from neighbourhood to regional scales and should be more strongly considered in future studies. Specific research priorities include humidity within the UBL, high-rise urban canopies and the development of long-term, spatially extensive measurement networks coupled strongly to model development
