This article examines the historical fantasy world created by Joan Aiken in the eleven volumes of her Wolves of Willoughby Chase series. In particular it looks at her subversion of historical reality by the creation of an alternative yet recognisable representation of our own world, using a wide range of events, and the remoulding of aspects of language and geography. It also discusses her reasons for writing in this form and explores the character of Dido Twite as heroine and major raison dtre of the series.This revised version was published online in May 2005 with corrections to the article title. 相似文献

The exploratory study focused on describing typical routines of preparing for winter outdoor play with preschool children
and their teachers. Naturalistic observations, interviews and photographs resulted in extensive examples of children’s development
in cognitive understanding of winter and winter-related concepts. Observations of teachers and assistants revealed task-oriented
perspectives including detailed strategies and planning. Asynchronous communication and directive language were typical of
teacher/child communication. Photo analyses confirmed physical skills used by preschoolers to accomplish dressing tasks and
extensive curricular changes to indoor environments. 相似文献

This article focuses on educational enterprises outside the formal sector, such as museums, botanical gardens and interactive
science centres. International research is drawn on to illuminate how design, culture, educational strategies and settings
combine to affect the way in which young people respond to experiences on offer, leading to analysis of the impact of such
settings in promoting learning, and the likely implications for those who staff such venues. Aikenhead’s concept of the educator
as ‘culture broker’ is developed to suggest ways in which learning might be best supported. It envisages a shift from ‘delivery’
strategies targeted at large groups towards approaches which focus on what learners choose to know about using dialogue between
children and ‘known and trusted people’. Analysis of observed responses in various settings is undertaken from a sociocultural
perspective using the notion of communities of practice. Implications for the roles of education managers and their staff
in further research are developed. 相似文献

Formal models for service composition have been proposed with the variation of the requirements of service developers. Some
famous models have provided checking and verification techniques and tools for the behavior of service composition. These
models generally focus much on the message flow of web services and neglecting the data contained in the exchanged messages
among services, which restrict the application range of these models and also the web service techniques. As new kind of services
with different protocols and communication methods have appeared, it is needed to model service composition from a new view
which is adapted to the new development in service area. In this paper we offer a function oriented model of service composition
which treats the composite service as a software system and specify the function of services which can be directly used to
the realization by service providers. 相似文献

The author articulates key stressors in the lives of families who are homeless. These stresses often combine with barriers such as lack of job opportunities and/or insensitive professionals. Strategies for helping homeless families overcome these barriers and related issues are presented. 相似文献

This paper describes and critiques a study tour to China of undergraduate and postgraduate business students in a large business faculty in a university with an emerging focus on internationalisation through building links with global business and industry. The study tour was designed to fit with the emerging trend towards internationalisation of business education wherein universities perceive themselves as being international universities based in one city rather than city-based universities who have international students. The literature on the difficulties of cross-cultural understanding and adjustment when business people sojourn to other countries is well documented. Yet, the same difficulties being encountered by students on short-term cultural immersion tours are yet to be adequately documented. This paper serves to address this gap in the literature by examining the experiences of 50 Australian and international students when confronted with a three week immersion into China's business, cultural and social practices. The paper explores the contributions of the study tour to academic understanding of globalisation. 相似文献

Pigeons' keypecking was reinforced by food on baseline schedules of multiple variable interval (VI) x VI x and on contrast schedules of multiple VI x VI y. Deprivation of food was varied by maintaining subjects at 75%, 85%, and 95% (+/- 2%) of their free-feeding weights. Positive and negative behavioral contrast were observed. The size of the contrast was not systematically altered by changes in deprivation. Positive and negative contrast were both larger later in the session than they were earlier. Within-session decreases in responding were steeper for the baseline than for the contrast schedules for positive contrast. Within-session decreases were steeper for the contrast than for the baseline schedules for negative contrast. These results were predicted by the idea that different amounts of habituation to the reinforcer during the baseline and contrast schedules contribute to behavioral contrast. The results show that contrast occurs under conditions that reduce the effect of the following component. The results support the assumption that positive and negative contrast are produced by symmetrical theoretical variables. 相似文献

In five conditioned taste aversion experiments with rats, summation, retardation, and preference tests were used to assess the effects of extinguishing a conditioned saccharin aversion for three or nine trials. In Experiment 1, a summation test showed that saccharin aversion extinguished over nine trials reduced the aversion to a merely conditioned flavor (vinegar), whereas three saccharin extinction trials did not subsequently influence the vinegar aversion. Experiment 2 clarified that result, with unpaired controls equated on flavor exposure prior to testing; the results with those controls suggested that the flavor extinguished for nine trials produced generalization decrement during testing. In Experiment 3, the saccharin aversion reconditioned slowly after nine extinction trials, but not after three. Those results suggested the development of latent inhibition after more than three extinction trials. Preference tests comparing saccharin consumption with a concurrently available fluid (water in Experiment 4, saline in Experiment 5) showed that the preference for saccharin was greater after nine extinction trials than after three. However, saccharin preference after nine extinction trials was not greater, as compared with that for either latent inhibition controls (Experiments 4 and 5) or a control given equated exposures to saccharin and trained to drink saline at a high rate prior to testing (Experiment 5). Concerns about whether conditioned inhibition has been demonstrated in any flavor aversion procedure are discussed. Our findings help explain both successes and failures in demonstrating postextinction conditioned response recovery effects reported in the conditioned taste aversion literature, and they can be explained using a memory interference account. 相似文献

Reading literacy and reading interest was examined in four primary schools in Papua New Guinea: in an international, suburban, settlement and village school. In this paper we present a summary of findings located within a local context and examine the implications as viewed through two lenses. From an ‘educational for equality’ perspective, the findings suggest a critical need to re‐evaluate the use of national testing to select children for further education and address the serious shortage of reading books in school libraries. From an ‘education for life’ perspective, the findings indicate a continuing need for community‐based actions together with innovative teacher education programs aimed at developing ways of strengthening the connections between home and school. 相似文献
