杭州市三江汇地区森林植被固碳抵消能源 排放能力评估及情景预测研究

森林植被固碳服务是生态系统服务评估的重要内容之一，在区域碳中和发挥着重要的碳汇作用。以生物量法和CASA模型法相结合，评估杭州市三江汇地区森林植被固碳能力；采用CEADs县级碳排放清单估算三江汇地区的能源碳排放量；综合碳汇和碳排评估该地区森林植被固碳对能源碳排放量的抵消率。从碳减排和增汇2个方面，对森林植被抵消能源碳排放的能力进行未来情景预测。研究结果表明：1)2017年三江汇地区森林植被固碳量为4.98×10⁴t，能源碳排放量为2.07×10⁶t，森林植被能源碳排放的抵消率为2.41%，三江汇森林植被能源碳抵消率呈现出“东低西高、北低南高”的空间格局；2)研究设置9个情景对2030年森林植被碳抵消率进行定量预测，预测结果显示研究区森林植被面积增加有利于提升森林植被对能源碳排放量的抵消能力，森林面积每增加5%，森林植被对能源碳排放量抵消率可提高0.12%～0.29%；减少人均能源碳排放对提高森林植被碳抵消能力的效果更为显著，人均能源碳排由2.77t/人降低为0.90和0.72t/人，森林植被碳抵消率可分别提高2.21%～2.43%和3.36%...

动力煤期货价格波动对我国煤炭经济影响研究*

采用中国煤炭价格指数、中国煤炭市场景气指数、中国煤炭市场预期指数和煤炭行业失业率作为我国煤炭经济发展的代表变量,选取2013年9月～2018年7月之间的交易数据,构建VAR模型,研究了动力煤期货价格与中国煤炭价格指数、中国煤炭市场景气指数、中国煤炭市场预期指数和煤炭行业失业率之间的动态关系。格兰杰因果检验表明:国内动力煤期货价格是中国煤炭价格指数、中国煤炭市场景气指数、中国煤炭市场预期指数和煤炭行业失业率的格兰杰原因。脉冲响应和方差分解分析表明:动力煤期货价格波动会引起中国煤炭市场景气度同方向变动;滞后2阶的动力煤期货价格上涨会使得中国煤炭市场预期指数上升;滞后2阶动力煤期货价格上涨,失业率降低。长期来看,动力煤期货价格上涨会使得失业率降低,动力煤期货价格与我国煤炭经济发展之间呈现动态均衡关系。     

A question of our marketing or our preconceptions: Commentary on the paper ‘A strategy for human factors/ergonomics: developing the discipline and profession’

The present paper is a commentary on the recently published IEA strategy for human factors/ergonomics (Dul, J., et al. (2012), A strategy for human factors/ergonomics: developing the discipline and profession. Ergonomics, 55(4), 377–395). Two main issues that demand attention are: (i) the way others understand our profession and discipline, and (ii) the way we understand our profession and added value to industry. First, it is advocated that the discussion on the future of human factors/ergonomics (HFE) should be focused more on the quality of the delivered value of HFE and less on its visibility and marketing. Second, the three fundamental characteristics of HFE, as proposed in the report, are discussed and the consequences of this proposal are further developed. Arguments are put forward on the endemic epistemological vagueness within the discipline and on the optimistic definition of its aim. Finally, a proposal is made at the epistemological level, which challenges some established convictions of the discipline. It is advocated that such an epistemological evolution may be necessary if HFE is to make progress towards contributing to system performance.

Practitioner Summary: The paper is a commentary on the IEA strategy for human factors/ergonomics. Issues discussed are, the way others understand our profession and the way we understand our profession and added value to industry. Some of the established convictions of the discipline are challenged and proposals are made to overcome these.     

Steeling ourselves for the electric vehicle revolution

Abstract

The automotive industry is changing with ever increasing speed. The current economic and environmental pressures mean that the vehicles of tomorrow will be very different to those we drive today. As new technologies are developed to enable these changes, the materials industry must respond quickly to ensure that they are both manufacturable and cost effective, as well as deliver the performance required to drive the industry forward. This article aims to identify the key technology developments, the challenges that they face and how Tata Steel is helping to overcome them.     

The Future IS Organization in a Flat World

ABSTRACT

The business world is becoming increasingly “flat” with regard to access to global markets and a global workforce. New operational priorities are emerging that require new IS capabilities. The linkage between these operational shifts and the changes required by an IS organization to develop new IS capabilities for a flattening world are identified and discussed.
