A Simple Unifying Measure of State Support for Postsecondary Education     

Philip A. Trostel  Justin M. Ronca 《Research in higher education》2009,50(3):215-247

Conflicting measures of state support for postsecondary education create confusion and misunderstanding that convolute debates about states’ postsecondary education funding. The use of multiple measures is largely unnecessary, though. A simple single measure is constructed that adequately quantifies both states’ postsecondary need and states’ ability to pay. Specifically, this study proposes measuring state support for postsecondary education as state postsecondary funding per high school graduate over the previous four years per dollar of per capita income.

Gender-specific patterns in patenting and publishing     

Rainer Frietsch  Inna Haller  Hariolf Grupp 《Research Policy》2009,38(4):590-599

Measuring the output of men and women in science and technology has previously been mostly restricted to case studies or small-scale surveys. Based on an analysis of patent and publication databases, this paper applies a methodology to systematically assign the gender to the names of inventors and authors. The method is applied to 14 countries. The results of this investigation reveal substantial differences across countries in terms of women's relative contribution¹ to science and technology, with the central European countries of Germany, Austria and Switzerland all ranking comparatively low in this respect. We also examine trends over time, showing that the data on women's share of publications - unlike the results for patents - hardly increase over time for the already better-performing nations.  相似文献   

物流产业生态位适宜度测度模型及其动态耦合演化     

朱芳阳  贾清显  谭保华 《科技管理研究》2019,39(1)

【】在经济步入新常态背景下,物流产业能否降本增效及生态发展事关中国经济增长范式转变的成败。本文从生态位角度研究物流产业问题,通过分析物流产业生态位适宜度动态演化规律与内部生态因子间的耦合、协调程度来科学预测各省区物流产业的发展趋势,研究表明各省区物流产业生态位适宜度在0.333～0.671范围内,难以适应物流产业绿色发展、生态发展要求,且受其内部生态因子之间耦合、协调程度的影响,并就此提出未来物流产业生态发展的政策建议。  相似文献   

Defining and measuring innovation in all sectors of the economy     

Fred Gault 《Research Policy》2018,47(3):617-622

This paper combines general definitions of innovation applicable in all economic sectors with a systems approach, to develop a conceptual framework for the statistical measurement of innovation. The resulting indicators can be used for monitoring and evaluation of innovation policies that have been implemented, as well as for international comparisons. The extension of harmonised innovation measurement to all economic sectors has implications for innovation research and for policy learning.  相似文献   

Methods and impact of correcting heart rate data errors during exercise in older adults     

Kathleen K Mangione  Kathy Macropol  Yanxia Jia  Michael Tevald  Shane Harris  Edward Wolff 《Measurement in physical education and exercise science》2018,22(4):356-363

Heart rate (HR) by time curves could be useful as a measure of treatment fidelity (TF). The purposes were to describe the frequency of common recording irregularities (e.g. errors) observed during exercise, validate a process to correct those errors, and determine whether there is a clinically meaningful benefit to data correction. In total, 1895 exercise sessions from 69 older adults with hip fracture were inspected for errors in the placement of event markers (duration of exercise) and signal artifacts. Marker errors occurred in 33% of the participants and corrected in 324 sessions. Signal artifacts occurred in 96% of the participants and eliminated in 702 sessions. Computer code was 85% accurate in detecting signal artifacts, compared to 97% for investigators. HR was significantly higher after correction, but the average change was only 0.69 + 1.20 beats per minute. An HR monitor showing HR by time curves (HRxTC) can be used to evaluate TF during exercise.  相似文献

科技创新团队创新增效运营模型研究   总被引：1，自引：1，他引：0  

万涛 《科技管理研究》2017,(17)

在科技创新团队运营阶段,运用生产效率测定指标构建团队创新增效运营模型,并提出增效的重点聚集于团队活动计划,而团队计划的重点是从假设探索向实践运用的方法研究。以某企业总部及其事业部18个科技创新团队为研究对象,在两个时间节点(项目开始后的第3个月和第9个月)对创新增效要因和创新效率之间的关系进行实地调查,研究结果显示:创新增效60%~80%的要因聚集于团队活动计划,第3个月以假设探索为中心的团队活动计划对于创新增效的影响极大,而第9个月以实践为中心的团队活动计划对于创新增效的影响极大。并验证了以上两个时间节点中团队活动计划重点的差异性。  相似文献   

生物质能源项目环境价值计量及潜在经济影响分析     

王斯一  张彩虹 《科技管理研究》2017,(11)

综合运用环境价值计量与经济影响评价法将生物质能源项目与煤炭项目进行对比,探讨将环境计量纳入经济评价后对生物质能源项目的促进作用。运用生命周期评价法定量分析生物质能源项目与煤炭相比所实现的环境价值,借助排放物环境价值概念,使生物质能源项目的环境效益得以转化为货币价值,并进一步将其带入改进的纳入环境成本与环境效益的环境经济综合评价体系中进行测算。通过案例项目计算发现,生物质能源项目具有显著环境效益,该项目可实现SO_2、CO、NO_x、烟尘减排量分别为8.105×106 kg、1.027 80×106 kg、4.101 91×106 kg和10.642 77×106 kg,环境效益价值为1 086.78万元,纳入环境效益的项目投资利润率、内部收益率、净现值都有显著提高,对项目实施有明显的促进作用。  相似文献
