论经济一体化下的科技产业化立法

在全球经济一体化之下,中国科技产业化的发展,需要立足WTO规则,及时作出立法应对,迎接时代的挑战。科技产业化的发展,是产、学、研一体化的发展,要通过立法支持政府财政对非盈利性的科研院所的补贴,要在立法上加强对自主知识产权和商业秘密的保护。我国科技产业化的发展,需要反垄断立法的支持。WTO规则的扩展,包括环境保护议题,需要规则先行,完善立法,推进科技产业化的可持续发展。

高星级酒店创建职业化团队的必要性及途径

在外资知名酒店集团的强大优势面前,我国高星级酒店在竞争中一直处于弱势地位,如何在发展过程中创建一支有职业化的工作技能、职业化的工作形象、职业化的工作态度、职业化的工作道德的职业化团队以便在蓬勃发展的经济形势下充分利用市场提供的机会、合理地规避风险,并争取在行业竞争中取得竞争优势是大多数酒店的当务之急。     

72205综采工作面3300V高压供电技术改造

随着工作面功率的加大,矿井电压过低造成设备启动困难或不启动现象,甚至造成欠电压跳闸,因此1140V电压等级升高到3300V将是煤矿发展的前进方向。

热焖法钢渣处理及综合利用工程实践

转炉钢渣是在转炉炼钢过程中产生的废渣,是炼钢的必然副产物,据钢铁工业协会统计数据显示,2012年钢渣产生量为6228万吨,如果处置利用不当,不仅污染周边环境,而且钢渣的含铁成分也白白浪费。钢渣的处理与利用巳成为钢铁企业发展循环经济、保护生态环境的一项紧迫任务。     

Profitability and Efficiency of High Nature Value Marginal Farming in England

The UK Brexit vote triggered a new wave of policy developments for a future outside the EU. In this context, we analyse the business performance of English hill and upland farms, characterised by marginal economic conditions but also high nature value (HNV). The analysis aims to help identify farm-level management and policy options for greater economic, environmental and social sustainability. Business performance is measured as technical efficiency and the occurrence and persistence of abnormal profits, estimated through stochastic frontier analysis and static and dynamic panel-data methods. The results help indicate rationales for recent trends including farm enlargement, farm family diversification, and agri-environment scheme entry. The single farm payment is found to be negatively associated with farm technical efficiency while agri-environmental subsidies were positively associated to short-term farm profitability. Farm adaptation and resilience during a period of likely turbulence in external circumstances is discussed in light of these findings, as well as potential parallels with marginal HNV areas across Europe.

ALLOWING FOR JUMP MEASUREMENTS IN VOLATILITY: A HIGH‐FREQUENCY FINANCIAL DATA ANALYSIS OF INDIVIDUAL STOCKS

Following recent advances in the non‐parametric realized volatility approach, we separately measure the discontinuous jump part of the quadratic variation process for individual stocks and incorporate it into heterogeneous autoregressive volatility models. We analyse the distributional properties of the jump measures vis‐à‐vis the corresponding realized volatility ones, and compare them to those of aggregate US market index series. We also demonstrate important gains in the forecasting accuracy of high‐frequency volatility models.     

Technology‐push,market‐demand and the missing safety‐pull: a case study of American Airlines Flight 587

Through a critical case study of the crash of American Airlines Flight 587, this paper draws upon ‘the Social Shaping of Technology’ (SST) approach to offer a reconceptualisation of the technology‐push and market‐demand model for High‐Reliably Organisations (HROs), providing support for a third factor, called here a ‘safety‐pull’. A safety‐pull is defined as organisationally supported reflexivity in which technology innovators and frontline operators collaborate to consider the potential implications of adopting new technologies in HROs and the complex ways this change may impact human operators' work performance, often in risky and unanticipated ways. In contrast to accidents occurring solely as the result of individual operator error, analysing the safety‐pull provides a way to tease out the wide range of factors that can contribute to HRO failures and offers a new SST perspective through which to examine high‐risk operations.
