Anticipating industry localization effects of clean technology deployment policies in developing countries

National ‘green growth’ strategies, which aim at decoupling economic development from adverse environmental impacts, have become a new paradigm for policymakers in developing countries. Many green growth strategies are based on policy instruments designed to incentivize the domestic deployment of relatively mature clean technologies and aim at fostering the formation of a local industry to develop and produce these technologies. While the empirical evidence on the localization effect of such policies in developing countries is mixed, there is a dearth of research systemically analyzing how differences between technologies affect patterns of localization, which could explain the observed variance. We address this gap and develop a typology which distinguishes four types of technologies requiring different types of capabilities. We do so by combining insights from the literature on technology transfer and catching-up of industries with insights from the literature on patterns of innovation across the technology life- cycle. We apply this typology to the case of low-emission development strategies and four exemplary low-carbon technologies, namely small and micro hydro power, wind turbines, electric cars, and solar cells, in order to analyze capability requirements, innovation patterns, and the effect of past deployment policies on industry localization. We synthesize these case studies and derive a heuristic to anticipate the localization effects of deployment policies for different types of technologies in countries with varying income levels. We argue that the heuristic can serve as starting point for policymakers aiming at clean technology industry localization. The paper concludes with a discussion of possible technology-specific green growth strategies for developing countries with different income levels and for international institutions supporting green growth.

A Comprehensive Study on Subsidence Control Using COSFLOW

Increasingly, mine subsidence is becoming a major issue of community concern. Among the measures of subsidence control, a more effective and economical technology, namely Overburden Grout Injection Technology (OGIT), is recently developed in China and Australia by injecting waste material into the bed separations during longwall mining to achieve subsidence control. The OGIT is proposed for the subsidence control in West Cliff Colliery located at the Southern Coalfield of the Sydney Basin, Australia. The three-dimensional finite element code COSFLOW is applied to investigate in a detail the bed separation developing with longwall mining and the effect of grout injecting into the separations in order to guide the subsidence control design when using the OGIT in West Cliff Colliery longwall mining practice.

广州地磁台环境干扰的监测与研究

通过对广州地磁台环境干扰源的监测，计算与分析得到：（1）不同时期产生的二个干扰源对地磁台1号墩磁场总强度测值的迭加影响为－25nT，与多台资料对比结果一致。（2）地磁台1号和5 ，1号与干扰源场区外Ⅰ号比测墩测得的磁场总强度、水平强度及垂直强度之差随时间的变化不明显，故认为广州地磁台环境干扰源目前尚属稳定。     

Nine requirements for the origin of Earth's life:Not at the hydrothermal vent,but in a nuclear geyser system

The origin of life on Earth remains enigmatic with diverse models and debates.Here we discuss essential requirements for the first emergence of life on our planet and propose the following nine requirements:(1)an energy source(ionizing radiation and thermal energy);(2)a supply of nutrients(P.K.REE.etc.);(3)a supply of life-constituting major elements;(4)a high concentration of reduced gases such as CH_4,HCN and NH_3;(5)dry-wet cycles to create membranes and polymerize RNA;(6)a non-toxic aqueous environment;(7)Na-poor water;(8)highly diversified environments,and(9)cyclic conditions,such as dayto-night,hot-to-cold etc.Based on these nine requirements,we evaluate previously proposed locations for the origin of Earth's life,including:(1)Darwin's "warm little pond",leading to a "prebiotic soup" for life;(2)panspermia or Neo-panspermia(succession model of panspermia);(3)transportation from/through Mars;(4)a deepsea hydrothermal system;(5)an on-land subduct ion-zone hot spring,and(6)a geyser systems driven by a natural nuclear reactor.We conclude that location(6)is the most ideal candidate for the o rigin point for Earth's life because of its efficiency in continuously supplying both the energy and the necessary materials for life,thereby maintaining the essential "cradle" for its initial development.We also emphasize that falsifiable working hypothesis provides an important tool to evaluate one of the biggest mysteries of the universe-the origin of life.
