许晓雯  蔡虹 《研究与发展管理》2004,16(5):11-17

针对R＆D活动绩效评价中大多没有将R＆D投入作为成本看待的做法,引入经济效率概念,指出在R＆D投入绩效评价中应贯彻产出/投入分析的思想。并尝试运用数据包络分析(DEA)方法对我国30个省市的R＆D投入绩效进行测度与评价,着重分析了东、中、西部三大地区R＆D投入绩效的差异。  相似文献

Standardization of a dilution method for cyclosporin (C2) estimation in renal transplant patients     

G. Kusumanjali  Chinnapu G. Reddy  A. S. Kanagasabapathy  Pragna Rao 《Indian journal of clinical biochemistry : IJCB》2005,20(2):146-149

Accurate monitoring of blood cyclosporin C2 levels is vital to prevent over immunosuppression and acute renal toxicity in patients who receive organ transplant. The matrix used to dilute patients’ C2 samples prior to the assay affected the final measured values. Hence there was a need to develop a method of dilution that would accurately estimate C2 levels when cyclosporin levels were beyond the calibration range of the method employed. Whole blood, cyclosporin free hemolysate and cell and protein free supernatant obtained after pretreatment of normal blood were used to dilute patients’ C2 samples. C2 was measured in 188 patients using the supernatant method of dilution. C2 was correlated with Co and dose of cyclosporin received by the patient. The use of cell and protein free supernatant obtained after pretreatment of normal blood as a C2 diluent detected higher levels of C2 in the sample. Measured C2 correlated significantly with Co and the cyclosporin dose received by the patient. The uniformly aqueous cell and protein free supernatant ensures uniform dilution of the patients’ C2 sample and measures higher cyclosporin levels.  相似文献

An integrative framework for studying,designing and conceptualising interactivity in children's digital books          下载免费PDF全文

Natalia Kucirkova 《British Educational Research Journal》2017,43(6):1168-1185

In the past five years, there have been significant changes concerning the material and design properties of digital books, with an impact on children's enjoyment and learning from reading on screen. Despite the rapid advances in technology, research on children's digital books is disjointed. This is because of no consistent approach to the study of interactivity, an under‐theorised relationship between print and digital books, and a binary design focused on either learning or playful engagement with digital books. Drawing on the discourse reminiscent of digital game designers, some developers, scholars and professionals celebrate interactivity in digital books as a possibility to motivate and engage children in reading, while a body of experimental research documents the negative impact of interactivity on children's story comprehension and vocabulary learning. This paper presents an integrative framework based on a comprehensive literature review and a content review of the hundred most popular children's digital interactive books. The framework offers: (1) methodological guidance and a definition of interactivity based on five key categories; (2) theoretical guidance based on the third‐space theory; and (3) innovative design and evaluation models based on a ‘method assemblage’. As such, the integrative framework provides new tools and perspectives to advance the field of children's digital books.  相似文献
