Policy Studies Journal, EarlyView.ABSTRACT As the Narrative Policy Framework (NPF) begins to unpack issues of power and narratives, the main focus has been on power‐over and domination rather than more transformative notions of power‐to and empowerment. This article draws on insights from gender and policy studies and suggests that the NPF benefits from adopting a multifaceted notion ...

Over-expression of Xylose isomerase/Xylulokinase and Construction of O2-tolerant hydrogenase in Klebsiella oxytoca HP1 [PDF]
, 2015 在石化燃料枯竭和全球气候变暖的双重危机下，氢气作为一种可再生、零排放和高热值的清洁能源载体而备受关注。关于氢能的研究主要围绕氢的制取和氢的利用两个方面展开。在众多制氢方式中，生物制氢因其生产成本低、原料来源丰富和环境污染小，从而成为制氢研究的热点。在氢的利用中，燃料电池技术一直以来都是研究的重点。氢酶是一种含金属的氧化还原酶，其广泛存在于微生物中，能够可逆地催化H+的还原和H2的氧化(2H++2e-↔H2)。无论是在氢的制取还是氢的利用中，氢酶都是氢能技术的核心之一 ...

A Research on Project Investment Decision-making of D Auto’s Small displacement Vehicle [PDF]
, 2015 中国作为目前世界上最大的汽车市场，吸引着几乎全球各大车厂来中国投资发展，定位豪华车的D汽车公司作为这其中的一个后来者，在做好品牌推广的同时，还需要推出能够提升销量，提高市场占有率的车型，如何抓住处于起步阶段的小排量豪华车这个利基市场是关键。另外，国家对乘用车企业平均燃料消耗值(CAFC)的限制也日趋严格，汽车企业除了通过发展新能源汽车以外，发展小排量车型也是切实有效的应对策略，D汽车公司的小排量车型项目在帮助D汽车公司满足国家CAFC的法规要求上也极为有效 ...

Preliminary Research of Abnormal Phenomena of Condensed Phase with Hydrogen(Deuterium) in Gas-Solid Phase [PDF]
, 2015 过去的一个世纪里，化石燃料支撑着工业和经济的发展，但化石燃料的有限储量和能源利用率低的现状导致我们不得不进行新能源的开发。1989年Fleischmann和Pons发现了简单条件下钯阴极电解重水的体系中产生300℃高温，超出了化学变化能够带来的能量，这种过量的热生成被称为异常过热现象。这种常规条件下大量产生能量的现象被称为人工可控的冷核聚变，为新能源的开发带来了希望。二十多年来，冷核聚变吸引了许多研究者投身其中，但由于实验条件复杂，结果重复性很低，该过热现象的真实性和可靠性至今仍没有得到可靠的证实 ...
