The majority of state nursery education in the United Kingdom is part‐time. Although there are exceptions this usually means that children attend either in the morning or afternoon. The format of the afternoon session can often resemble the morning session, offering similar activities. This paper sets out to examine the comparative quality of experience for children attending part‐time nursery at different times of the day. It looks particularly at storytime, when the whole group of children is brought together to share a story. The findings suggest the two sessions are not of equal value to the children, that children may not be performing as well in the afternoon and that the traditional group storytime may not be as effective for the afternoon children. This type of storytime may need to be adapted/changed to match the needs of the particular group of children, taking into consideration performance during the day. Finally, suggestions are given for other ways to ensure children have worthwhile story experiences. 相似文献

This paper identifies two conceptions of security in contemporary concerns over the vulnerability of computers and networks
to hostile attack. One is derived from individual-focused conceptions of computer security developed in computer science and
engineering. The other is informed by the concerns of national security agencies of government as well as those of corporate
intellectual property owners. A comparative evaluation of these two conceptions utilizes the theoretical construct of “securitization,”developed
by the Copenhagen School of International Relations.
This article has been on the drawing boards for longer than I dare to admit. Along the way, many have helped its development
by generously sharing their wisdom: James Der Derian, Niva Elkin-Koren, Ed Felten, Batya Friedman, Lene Hansen, audiences

The present work describes the operation and simulation of a microfluidic laminar-flow mixer. Diffusive mixing takes place between a core solution containing lipids in ethanol and a sheath solution containing aqueous buffer, leading to self assembly of liposomes. Present device architecture hydrodynamically focuses the lipid solution into a cylindrical core positioned at the center of a microfluidic channel of 125 × 125-μm2 cross-section. Use of the device produces liposomes in the size range of 100–300 nm, with larger liposomes forming at greater ionic strength in the sheath solution and at lower lipid concentration in the core solution. Finite element simulations compute the concentration distributions of solutes at axial distances of greater than 100 channel widths. These simulations reduce computation time and enable computation at long axial distances by utilizing long hexahedral elements in the axial flow region and fine tetrahedral elements in the hydrodynamic focusing region. Present meshing technique is generally useful for simulation of long microfluidic channels and is fully implementable using comsol Multiphysics. Confocal microscopy provides experimental validation of the simulations using fluorescent solutions containing fluorescein or enhanced green fluorescent protein. 相似文献

Seventy-six librarians participated in a series of focus groups in support of research exploring the skills, knowledge and attributes required by the contemporary library and information professional in a world of ever changing technology. The project was funded by the Australian Learning and Teaching Council. Text mining data analysis revealed three main thematic clusters (libraries, people, jobs) and one minor thematic cluster (community). Library 2.0 was broadly viewed by participants as being about change whilst librarian 2.0 was perceived by participants as not a new creation but just about good librarian practices. Participants expressed the general belief that personality traits, not just qualifications, were critical to be a successful librarian or information worker in the future. 相似文献
