Steve Shann’s latest book is a novel called The Worlds of Harriet Henderson. It’s about 15-year-old Harriet Henderson who has a new English teacher, Molly McInness, and all at once school seems full of possibilities. But, inspired by Molly and impelled by her own adolescent restlessness, Harriet makes an impulsive decision, a decision that takes her, her teacher and her new friend into complex and dangerous worlds. The novel is a natural extension of Shann’s earlier articles and books arguing that mythopoetics – the use of intuition and imagination to reveal the ordinarily unseen – is a legitimate scholarly methodology. In this article, Shann uses extracts from a 2015 journal he kept as he began to think about writing a novel. 相似文献

As the field of Mind, Brain, and Education seeks new ways to credibly bridge the gap between neuroscience, the cognitive sciences, and education, various connections are being developed and tested. This article presents a framework and offers examples of one approach, predictive modeling within a virtual educational system that can include representations from the neural level to the policy level. Researchers could calibrate, test, and question the model, potentially providing quicker, more efficient, and more responsible ways of making advances in the developing educational field. Virtual investigations using models with this sort of capability can supplement the valuable information derived from carrying out policy and instructional experiments in real educational contexts. 相似文献

In response to Michiel van Eijck and Wolff-Michael Roth’s article and Michael Mueller and Deborah Tippin’s rejoinder, we explore
traditional ecological knowledges as science education. Adopting a stance of situated partial perspectives, and drawing on
selected literature in science and technology studies and feminist postcolonial theories, we reflect on acts of dissociation,
localism, utilitarianism and principled pluralism as referent points for epistemological and pedagogical renewal. In conclusion,
we return to an opening narrative of cultural loss combined with an invitation to imagine science pedagogy as a site of possibility,
vulnerability and fragility. Such an invitation, we suggest, involves troubling manifestations of pedagogical and epistemic
desires of normative closures and certitude. What now remains is a series of tensions and open questions for further work. 相似文献

Question:
How can the user''s access to health information, especially full-text articles, be improved? The solution is building and evaluating the Health SmartLibrary (HSL).Setting:
The setting is the Galter Health Sciences Library, Feinberg School of Medicine, Northwestern University.Method:
The HSL was built on web-based personalization and customization tools: My E-Resources, Stay Current, Quick Search, and File Cabinet. Personalization and customization data were tracked to show user activity with these value-added, online services.Main Results:
Registration data indicated that users were receptive to personalized resource selection and that the automated application of specialty-based, personalized HSLs was more frequently adopted than manual customization by users. Those who did customize customized My E-Resources and Stay Current more often than Quick Search and File Cabinet. Most of those who customized did so only once.Conclusion:
Users did not always take advantage of the services designed to aid their library research experiences. When personalization is available at registration, users readily accepted it. Customization tools were used less frequently; however, more research is needed to determine why this was the case. 相似文献165.
In this paper, we present a microfluidic chip that is capable of measuring electrical conductance through gap junction channels in a 2-dimensional cell sheet. The chip utilizes a tri-stream laminar flow to create a non-conductive sucrose gap between the two conducting solutions so that electrical current can pass across the sucrose gap only through the cells. Using the chip, we tested the effect of a gap junction inhibitor, 2-APB, on the electrical coupling of connexin 43 (Cx43) gap junction channels in NRK-49F cells. We found that 2-APB reversibly blocks the conductivity in a dose-dependent manner. The tri-stream chip further allows us to simultaneously follow the conductance changes and dye diffusion in real time. We show that 2-APB affects both conductance and diffusion, supporting the interpretation that both sets of data reflect the same gap junction activity. The chip provides a generic platform to investigate gap junction properties and to screen drugs that may inhibit or potentiate gap junction transmission. 相似文献

The purpose of the present study was to analyse the variability in clubhead presentation to the ball and the resulting ball impact location on the club face for a range of golfers of different ability. A total of 285 male and female participants hit multiple shots using one of four proprietary drivers. Self-reported handicap was used to quantify a participant's golfing ability. A bespoke motion capture system and user-written algorithms was used to track the clubhead just before and at impact, measuring clubhead speed, clubhead orientation, and impact location. A Doppler radar was used to measure golf ball speed. Generally, golfers of higher skill (lower handicap) generated increased clubhead speed and increased efficiency (ratio of ball speed to clubhead speed). Non-parametric statistical tests showed that low-handicap golfers exhibit significantly lower variability from shot to shot in clubhead speed, efficiency, impact location, attack angle, club path, and face angle compared with high-handicap golfers. 相似文献

There is little conclusive evidence about the state of the IS curriculum in the UK. This paper presents the results of a detailed survey about the provision of Information Systems (IS) undergraduate degree courses in the UK using the newly developed IS 2010 curriculum guidelines as its basis. IS 2010 identifies three main categories of knowledge that underpin the essence of IS as an academic subject: IS Specific Knowledge and Skills, Domain Fundamentals and Foundational Knowledge and Skills. Our desire to offer a holistic and conclusive representation of the curriculum is supported by the development of an IS curriculum survey framework that caters for the mapping of every subject that populates the IS curricula of undergraduate degrees in the UK, including subjects that are generic or are derived from other hierarchical disciplines. 相似文献

The aim of this study was to quantify and explain the effect of shaft stiffness on the dynamics of golf drives. Twenty golfers performed swings with two clubs designed to differ only in shaft bending stiffness. Wrist kinematics and clubhead presentation to the ball were determined using optical motion capture systems in conjunction with a radar device for capturing ball speed, launch angle, and spin. Shaft stiffness had a marginally small effect on clubhead and ball speeds, which increased by 0.45% (p < 0.001) and 0.7% (p = 0.008), respectively, for the less stiff club. Two factors directly contributed to these increases: (i) a faster recovery of the lower flex shaft from lag to lead bending just before impact (p < 0.001); and (ii) an increase of 0.4% in angular velocity of the grip of the lower flex club at impact (p = 0.003). Unsurprisingly, decreases in shaft stiffness led to more shaft bending at the transition from backswing to downswing (p < 0.001). Contrary to previous research, lead bending at impact marginally increased for the stiffer shaft (p = 0.003). Overall, and taking effect sizes into account, the changes in shaft stiffness in isolation did not have a meaningful effect on the measured parameters, for the type of shaft investigated. 相似文献

Over the last 20 years, states and provinces have become increasingly involved in the financing and administration of elementary and secondary education. Local school boards, however, still retain control over key aspects of the provision of education. Historically, these boards were organized at the community level so as to meet the wants of the local community. Today, states and provinces have become more interested in consolidating school boards and moving to a more centralized funding scheme. Do these changes result in improved student achievement? This paper attempts to answer these questions by examining the school board consolidation and funding changes instituted by the province of Ontario. We differentiate the effects of the policy changes based on observed differences in the school boards prior to consolidation. We show that students in previously high wealth school boards perform worse after the policy change compared to students in previously low wealth school boards. 相似文献
