Exploring the role of instrument design and instrument interaction for eco-innovation: a survey-based analysis of renewable energy innovation in Germany

Empirical research on eco-innovation has produced a substantive body of literature on the relevance of regulation for stimulating such innovation. Much of this work on the role of policy for eco-innovation relies on econometric analyses of company survey data. In this regard, the eco-innovation module introduced in 2008/9 in the Community Innova-tion Survey serves as an important data source that has helped improve our under-standing of the role of environmental and innovation policy for eco-innovation in the Eu-ropean Union (EU). However, so far, this data source has provided only limited oppor-tunities to generate insights into the role of instrument design and instrument interaction for eco-innovation. In this chapter, we present a first attempt to measure such aspects in a company innovation survey based on the example of renewable energy innovation in Germany. In particular, we explore to what extent the design of the German Renewa-ble Energy Sources Act (and the interaction of its feed-in tariffs with the EU emissions trading system) correlates with innovation in renewable power generation technologies. We find instrument design features but not instrument type to be related to eco-innovation. In addition, our exploratory study provides evidence for an interaction effect between climate policy and renewables support policy. Based on these findings, we discuss implications for future research on the role of policy in eco-innovation

Intravitreal Administration of HA-1077, a ROCK Inhibitor, Improves Retinal Function in a Mouse Model of Huntington Disease

Huntington disease (HD) is an inherited neurodegenerative disease that affects multiple brain regions. It is caused by an expanded polyglutamine tract in huntingtin (Htt). The development of therapies for HD and other neurodegenerative diseases has been h

The interplanetary exchange of photosynthesis

Panspermia, the transfer of organisms from one planet to another, either through interplanetary or interstellar space, remains speculation. However, its potential can be experimentally tested. Conceptually, it is island biogeography on an interplanetary or interstellar scale. Of special interest is the possibility of the transfer of oxygenic photosynthesis between one planet and another, as it can initiate large scale biospheric productivity. Photosynthetic organisms, which must live near the surface of rocks, can be shown experimentally to be subject to destruction during atmospheric transit. Many of them grow as vegetative cells, which are shown experimentally to be susceptible to destruction by shock during impact ejection, although the effectiveness of this dispersal filter can be shown to be mitigated by the characteristics of the cells and their local environment. Collectively these, and other, experiments reveal the particular barriers to the cross-inoculation of photosynthesis. If oxygen biosignatures are eventually found in the atmospheres of extrasolar planets, understanding the potential for the interplanetary exchange of photosynthesis will aid in their interpretation
