This article reports on a study in progress which is exploring the potential for teaching Key Stage 2 pupils about the grammar and vocabulary of English with materials based on an electronically stored corpus of texts and associated software. It includes examples of the teaching activities used and extracts of discussions between the researcher and two groups of pupils. It illustrates children beginning to explore the distinction between ‘open’ and ‘closed’ classes of words. 相似文献

Valuing the Arts: A Contingent Valuation Approach 总被引:5,自引:3,他引:2
Eric Thompson Mark Berger Glenn Blomquist Steven Allen 《Journal of Cultural Economics》2002,26(2):87-113
Government funding of the arts has received considerable attention in the United States in recent years. Efforts to cut funding to the National Endowment for the Arts and declining budgets for state arts agencies have raised questions about how much individuals value the arts. This paper applies the contingent valuation method to assess this value, using surveys of random households and of arts patrons. Our analysis estimated a mean willingness to pay (WTP) among all Kentucky households from $6 to$27, depending on the estimation technique used and on whether the scenario discussed is to increase arts performances by 25 per cent, or to avoid a 25per cent or 50 per cent decrease in the number of performances. Among arts patron households, the mean WTP ranges from $61 to $132.Consumer demand for arts performances in large part follows a predictable pattern. The likelihood of respondents agreeing to make the donation that is requested rises as the size of the donation decreases. The likelihood is higher to avoid a 50 per cent decline in performances than to avoid a 25 percent decline in performances. The mean WTP rises with income, and arts patron households have a much higher WTP than all households. WTP rises with on-site use factors such as frequency of attendance. The WTP also rises for arts patrons households with off-site use such as watching arts events on television or reading about the arts in newspapers and magazines. 相似文献

Military officials continually search for improvements in processes that focus on high‐performance outcomes. This qualitative study investigated process improvements of two departments within the Naval Diving and Salvage Training Center (the Security Department and the Testing Department) by assessing performance levels of the two departments using a combinatorial model from human performance theory and Six Sigma theory. Study findings produced strong empirical evidence with specific recommendations for initiating cost‐effective interventions for improvements. The Behavior Engineering Model was used to identify possible solutions to post‐training performance gaps identified during the evaluation. 相似文献

Children at risk for early reading difficulties were identified on entry into kindergarten, and half of these children received small-group intervention two to three times a week during their kindergarten year. The other half received whatever remedial assistance was offered by their home schools. These children were again assessed at the beginning of first grade, and those who continued to have difficulties in reading received either one-to-one daily tutoring offered by project teachers from the beginning to the end of first grade or whatever remedial assistance was offered by their home schools over the same time period. All target children were periodically assessed through the end of third grade. Results suggest that either kindergarten intervention alone or kindergarten intervention combined with first-grade intervention are both useful vehicles for preventing early and long-term reading difficulties in most at-risk children. 相似文献

Cancer is a genetic disorder.Although heredi-tary cancers account for only a small fraction of all tumors,most cancers are caused by a variable mix of heredity and environment that leads to accumulations of genetic alterations and then uncontrolled cell pro-liferations(Kops et al.,2005).In addition,genetic alteration is one of the a few most important bio-logical factors that determine the diagnosis and prognosis of different cancers and dictate the treat-ment strategies for cancer patients.Fu… 相似文献
