In recent years, NHS Ambulance Trusts throughout the UK have consistently failed to achieve their response time targets for both actual and potential life-threatening calls. To avoid a media and public outcry, the NHS response has been to change the basic parameters upon which the response time targets are calculated. An action learning study, which considered patient experience from initial response to outcome, concluded that the ambulance service must move away from the nearest crew response model to one which provides a defined multi-organisational service to specific categories of need. A key issue with the learning sets, which were made up of front-line crews, was understanding the Trust-wide picture and where acceptable new procedures could provide economic benefits to the Trust, benefits to the patients and help achieve the response time targets. A simulation model driven by parameters agreed by the action learning sets provided proof that new procedures would generate the required benefits. The learning sets also identified that the public should adjust their expectations to understanding that an immediate front-line ambulance response would only be despatched in life-threatening cases, but there would be alternative slower responses for all other cases. 相似文献

A Gagné-style learning hierarchy often permits a large number of alternate linear arrangements (sequences) of instructional objectives. An alternative is described here to traditional methods of choosing between sequences. Its premise is that, for every sequence, a value temed thememory load can be calculated which is theoretically related to the probability that students will fail to recall prerequisite objectives. A graph theoretic approach is taken in presenting an algorithm which generates a minimal memory load sequence from a learning tree, a restricted but frequently encountered type of learning hierarchy. In order to assess the effectiveness of the algorithm in generating low memory load sequences when given hierarchies which are not trees, it was applied to several published examples of learning hierarchies. The results indicated that the algorithm is effective as an heuristic, especially when combined with a hill-descending procedure which attempts to incrementally improve the generated sequence. 相似文献

Pigeons were trained to match temporal (2 and 8 sec of keylight) and color (red and green) samples to vertical and horizontal comparison stimuli. In Experiment 1, samples that were associated with the same correct comparison stimulus displayed similar retention functions; and there was no significant choose-short effect following temporal samples. This finding was replicated in Phase 1 of Experiment 2 for birds maintained on the many-to-one mapping, and it was also obtained in birds that had been switched to a one-to-one mapping by changing the comparison stimuli following color samples. However, in Phase 2 of Experiment 2, when the one-to-one mapping was produced by changing the comparison stimuli following temporal samples, a significant choose-short effect was observed. In Experiment 3, intratrial interference tests gave evidence of temporal summation effects when either temporal presamples or color presamples preceded temporal targets. This occurred even though these interference tests followed delay tests that failed to reveal significant choose-short effects. The absence of significant choose-short effects in Experiment 1 and in Phase 1 of Experiment 2 indicates that temporal samples are not retrospectively and analogically coded when temporal and nontemporal samples are mapped onto the same set of comparisons The interference test results suggest that the temporal summation effect arises from nonmemorial properties of the timing system and is independent of the memory code being used 相似文献

Seventy‐four students read passages from an individually administered test of reading comprehension (a subtest from the Test of Dyslexia, a test of reading and related abilities currently in development; McCallum & Bell, 2001), and then answered literal and inferential questions. Students were randomly assigned to one of two conditions; 39 students read the passages silently and 35 read orally, with time recorded for each passage read. Comprehension and time were dependent measures for a Multivariate Analysis of Covariance (MANCOVA) and two follow‐up Analyses of Covariance (ANCOVA). After controlling for reading ability, results from the MANCOVA showed a significant combined effect ( p < .05); however, a comparison of mean reading comprehension scores showed no significant difference between silent readers and oral readers ( p > .05). On the other hand, with reading ability controlled, silent readers took significantly less time to complete passages compared to those who read orally ( p < .02). In fact, students took 30% longer to read orally than silently, on average. When test directions do not specify either oral or silent reading and error analysis is not a goal, testing will be more efficient via silent responding with no loss of comprehension. © 2004 Wiley Periodicals, Inc.

This research set out to investigate how, in a post-conflict area, parental preferences and household characteristics affect school choice for their children. A multinomial logit is used to model the relationship between education preferences and the selection of schools for 954 households in Freetown and neighboring districts, Western Area, Sierra Leone. The increased economic well-being of a family tends to increase the likelihood of choosing a nongovernment school. As a child gets older parents are more likely to select government over nongovernment schools. For girls, parents are twice as likely to select a nongovernmental organization (NGO) school than a government one. Where parental preference for girls is a “safe environment” government is the preferred choice over a private proprietor school. Interestingly, the level of household education does not affect the likelihood of attending any school management type. 相似文献

A random sample of 482 teachers in grades 3 through 8 from across the United States were surveyed about (a) their perceptions of the version of the Common Core writing and language standards adopted by their state and their state’s writing assessment, (b) their preparation to teach writing, and (c) their self-efficacy beliefs for teaching writing. Regardless of grade, a majority of teachers believed that the adopted standards are more rigorous than prior standards, provide clear expectations for students that can be straightforwardly translated into activities and lessons, and have pushed them to address writing more often. However, many surveyed felt the new writing and language standards are too numerous to cover, omit key aspects of writing development, and may be inappropriate for struggling writers. Moreover, most did not feel that professional development efforts have been sufficient to achieve successful implementation, and nearly one in five respondents was not familiar with the standards. The respondents were generally less sanguine regarding their state’s writing test, with elementary teachers even less positive than middle school teachers on some aspects, though nearly a third were unfamiliar with their state test. A majority believed state writing tests, though more rigorous than prior tests, fail to address important aspects of writing development, do not accommodate the needs of students with diverse abilities, and require more time than is available to prepare students. Additionally, many teachers believed professional development efforts have been insufficient to help them understand measurement properties of the assessments and how to use test data to identify students’ writing needs. Teachers who were better prepared to teach writing and who held more positive personal teaching efficacy beliefs for writing exhibited generally more positive perceptions of their state’s standards. In contrast, only teacher efficacy beliefs made a unique contribution to the survey respondents’ attitudes and beliefs about their state’s writing test. 相似文献

It has been argued by some (e.g. the Confederation of British Industry [CBI]) that graduates lack the skills that render them employable. In particular, graduates of science, technology, engineering and mathematics (STEM) subjects are often portrayed as being unready for the world of work. This study uses three large-scale national data-sets from the UK to explore this assertion, including the results of the Destinations of Leavers from Higher Education surveys. It reports analysis of 22,207 individuals who graduated from their first degree in 2007, and works from the hypothesis that those entering the workforce and then returning for taught postgraduate study are primarily doing so due to underemployment in the period following graduation. The study uses binary logistic regression and finds that a range of educational, demographic and employment-based variables have a significant relationship with the propensity to return for taught postgraduate study. Of particular note, those returning tend to be high achievers from elite universities in low-skill work after graduation, as well as women and those from minority ethnic communities; this suggests a mix of individual and structural factors at work. In addition, STEM graduates were significantly less likely to return, apparently challenging the argument advanced by the CBI. 相似文献
