Richard Owen and the sea-serpent     

Regal B 《Endeavour》2012,36(2):65-68

The well known naturalist, Richard Owen, had a career long engagement with monstrous creatures. In the 1830s he famously christened large fossil reptiles, Dinosauria. He investigated fossil marine reptiles as well as the giant moa. He also looked into the sea-serpents and sea monsters then drawing wide public attention. He actively collected letters and analyzed correspondence on the topic, consulted with the admiralty on reports of Royal Navy encounters and sightings, and commented in the public press. He concluded that such reports were based upon misidentifications of whales and other large marine mammals, and not run-ins with mythological creatures. His work on the sea-serpent shows that rather than discount the idea out of hand, a number of high profile naturalists were intrigued by monsters and attempted to understand what they were. His work is key to understanding the skepticism over monsters held by modern mainstream science. This skepticism opened the field to later amateur investigators.  相似文献   

Grand missions of agricultural innovation     

Brian D. Wright 《Research Policy》2012,41(10):1716-1728

This paper discusses three related examples of mission-oriented agricultural institutional innovations associated with substantial crop yield increases in the 20th century. It begins with the implementation of the United States Land-Grant System and then discusses in turn the planning and implementation of the two grand missions that led successively to the yield increases in wheat and rice that heralded the onset of the “Green Revolution.” It notes the remarkable role of the Rockefeller Foundation in identifying these two missions, and selecting personnel developed within the land-grant system to execute them with remarkable effectiveness.  相似文献

Automatic detection of collisions in elite level rugby union using a wearable sensing device     

Daniel Kelly  Garrett F. Coughlan  Brian S. Green  Brian Caulfield 《Sports Engineering》2012,15(2):81-92

Elite rugby union teams currently employ the latest technology to monitor and evaluate the physical demands of training and games on their players. Tackling has been shown to be the most common cause of injury in rugby union, yet current player monitoring technology does not effectively evaluate player tackling measurements. Currently, to evaluate measurements specific to player tackles, a time-consuming manual analysis of player sensor data and video footage is required. The purpose of this work is to investigate tackle modeling techniques which can be utilised to automatically detect player tackles and collisions using sensing technology already being used by elite international and club level rugby union teams. This paper discusses issues relevant to automatic tackle analysis, describes a technique to detect tackles using sensing data and validates the technique by comparing automatically detected collisions to manually labeled collisions using data from elite club and international level players. The results of the validation show that the system is able to consistently identify collisions with very few false positives and false negatives, achieving a recall and precision rating of 0.933 and 0.958, respectively. The aim is that the automatically detected tackles can provide coaching, medical and strength and conditioning staff with objective tackle-specific measurements, in real time, which can be used in injury prevention and rehabilitation strategies.  相似文献   

Stability, change, and correlates of the peer relationships of young children with mild developmental delays     

Guralnick MJ  Hammond MA  Connor RT  Neville B 《Child development》2006,77(2):312-324

The peer relationships of young children with mild developmental (cognitive) delays recruited at 4-6 years of age were examined in a longitudinal study across a 2-year period. Results revealed only modest increases in children's peer interactions, a high degree of intraindividual stability, and the existence of a poorly organized and conflict-prone pattern of peer interactions. Child cognitive and language levels as well as family stress and support were associated with children's peer interactions. A subgroup was identified of initially low interactors who were at especially high risk for future peer interaction problems. These findings further underscore the importance of designing and implementing early intervention programs in the area of peer relationships for children with mild developmental delays.  相似文献   

A simple and effective protein folding activity suitable for large lectures     

White B 《CBE life sciences education》2006,5(3):264-269

This article describes a simple and inexpensive hands-on simulation of protein folding suitable for use in large lecture classes. This activity uses a minimum of parts, tools, and skill to simulate some of the fundamental principles of protein folding. The major concepts targeted are that proteins begin as linear polypeptides and fold to three-dimensional structures, noncovalent interactions drive this folding process, and the final folded shape of a protein depends on its amino acid sequence. At the start of the activity, students are given pieces of insulated wire from which they each construct and fold their own polypeptide. This activity was evaluated in three ways. A random sample of student-generated polypeptides collected after the activity shows that most students were able to create an appropriate structure. After this activity, students (n = 154) completed an open-ended survey. Their responses showed that more than three-quarters of the students learned one or more of the core concepts being demonstrated. Finally, a follow-up survey was conducted seven weeks after the activity; responses to this survey (n = 63) showed that a similar fraction of students still retained these key concepts. This activity should be useful in large introductory-level college biology or biochemistry lectures.  相似文献   

The mentoring dilemma: guidance and/or direction?     

Brian Gay  Joan Stephenson 《Mentoring & Tutoring: Partnership in Learning》2013,21(1-2):43-54

Abstract

How effective is your mentoring programme? How does the nature of a mentoring programme influence outcomes? By looking beneath the process and practice, an examination, analysis and classification of the nature of current real‐life mentoring practice is made and a template for the identification of your own project is presented.  相似文献

Novice nurses encounter numerous factors that impact on their learning in the complex healthcare workplace. Registered nurses often work one‐on‐one with novices as preceptors to facilitate the development of novices’ clinical skills and socialisation into the profession. This paper explores the concept of preceptorship from novice nurses’ and preceptors’ perspective, drawing upon data from a project between a large healthcare organisation and a university in Melbourne, Australia. The study, framed in ethnomethodology, included fieldwork observation, interviews and student surveys; this paper focuses on data collected over a series of individual interviews with nursing students (n = 28) and preceptors (n = 25). Thematic analysis yielded six key themes: workplace socialisation, empathy, individuality, willingness to engage, changing support and a realisation [by novices about the preceptor role]. Findings highlight the complexity of workplace learning that is influenced by the idiosyncrasies of the individuals involved and the social milieu in which the learning takes place.  相似文献
