Developing an action learning way of working within a leadership context in higher education: barriers and enablers

This account of practice considers action learning within an accredited leadership course at a post-1992 university. It outlines a more individualistic approach than that envisioned by Reg Revans and questions how this technique, inherited from a Staff Development colleague, could potentially be improved.

Fractional order sliding mode control of a pneumatic position servo system

Gas flow has fractional order dynamics; therefore, it is reasonable to assume that the pneumatic systems with a proportional valve to regulate gas flow have fractional order dynamics as well. There is a hypothesis that the fractional order control has better control performance for this inherent fractional order system, although the model used for fractional controller design is integer order. To test this hypothesis, a fractional order sliding mode controller is proposed to control the pneumatic position servo system, which is based on the exponential reaching law. In this method, the fractional order derivative is introduced into the sliding mode surface. The stability of the controller is proven using Lyapunov theorem. Since the pressure sensor is not required, the control system configuration is simple and inexpensive. The experimental results presented indicate the proposed method has better control performance than the fractional order proportional integral derivative (FPID) controller and some conventional integral order control methods. Points to be noticed here are that the fractional order sliding mode control is superior to the integral order sliding mode counterpart, and the FPID is superior to the corresponding integral order PID, both with optimal parameters. Among all the methods compared, the proposed method achieves the highest tracking accuracy. Moreover, the proposed controller has less chattering in the manipulated variable, the energy consumption of the controller is therefore substantially reduced.     

Delineating policy mixes: Contrasting top-down and bottom-up approaches to the case of energy-storage policy in California

In the light of pressing societal challenges such as climate change and resource scarcity, scholars are increasingly interested in studying policy mixes in the context of sustainability transitions. However, despite numerous conceptual advances and empirical insights, researchers still lack universal criteria or accepted heuristics for delineating policy mixes in these complex policy spaces. We address this gap by conducting an extensive review of the literature, synthesizing best practices, and developing an analytical framework that provides researchers with two archetypical methodological approaches. The top-down approach builds on the idea that the elements of a policy mix originate from an overarching strategic intent. By contrast, the bottom-up approach starts from the definition of a focal impact domain that is affected by a range of policy instruments. For each approach, we outline a systematic analytical procedure, then implement it to scrutinize how policy affects the emerging technological domain of energy storage in California. We find that each approach has particular advantages that render it useful for certain policy mix analyses. Discussing how researchers may choose between the two approaches or leverage their complementarities, we seek to provide the basis for a consistent research program building on the policy mix framework.     

环境规制与行业异质性对制造业企业技术创新的影响——基于我国沿海与内陆地区的比较

基于行业异质性视角,以2010年—2015年我国省级制造业规模以上企业为样本,将环境规制划分为正式型与非正式型两类,对比分析了沿海与内陆地区环境规制、行业异质性对企业技术创新影响的差异。研究发现：(1)从制造业全行业来看,正式型环境规制对技术创新的影响作用在沿海与内陆地区均显著为正;非正式型环境规制对技术创新的影响作用在沿海地区显著为正,在内陆地区作用不显著;环境规制强度对技术创新的影响作用在沿海地区显著为负,在内陆地区显著为正。(2)环境规制对高污染行业的技术创新作用在沿海地区显著为正,在内陆地区显著为负。(3)环境规制对高搬迁成本行业的技术创新作用在沿海地区显著为正,在内陆地区显著为负。     

基于深化科技体制改革的陕西技术创新模式转变路径与政策体系研究

经过改革开放40年的经济和科技体制改革,我国科技力量的数量布局已发生了根本性变化,到2017年,企业占全社会研发经费总量达到78%,已取代高校、科研院所成为全社会研发经费投入的主体,我国科技成果转化模式向技术创新模式转变的微观基础条件已经形成。但在陕西,企业占全社会研发经费总量仅为47.7%,这种微观基础远未形成。在新时代,陕西实现技术创新模式转变的路径和政策措施主要一是以加大企业研发投入强度为着力点,促进企业真正成为技术创新的主体;二是以体制机制创新为保障,提高科技成果本地转化率;三是以切实落实带整体突破性的“陕九条”政策为突破口,引导科技创新人才在企业技术创新活动中“名利双收”并向企业流动;四是以推动企业走自主创新道路为方向,实现陕西强大的国家科技从创新链到产业链上下游链接下游的原始创新,强化大型企业和工程的集成创新,突出中小企业引进消化吸收再创新;五是要切实解决政府激励企业技术创新政策过剩、越位和错位问题,如要把激励企业技术创新事前的财政补贴,转向面向消费市场补贴,即把创新经费补贴给需求方、采购方、技术使用方或者是企业取得重大创新之后再予补贴。     

统计标准变更折射出的北京市工业企业技术创新现状

研究采用Biennial Malmquist指数,利用微观层面企业数据,测算了统计标准提高后北京市工业企业技术创新能力的变化;不仅为界定不同行业技术创新层次和基本特征提供了新依据,而且验证了中国工业TFP增长更多依赖技术进步、导致技术效率持续恶化的观点。鉴于该趋势在小型企业中同样突出,反映出我国工业企业急功近利的短期行为已相当普遍,培育良好的市场运行准则和积极长效的发展环境是除了关注工业企业TFP增长外,更应尽早着手解决的问题。
