As policymakers and automotive stakeholders around the world seek to accelerate the electrification of road transport with hydrogen, this study focuses on the experiences of Germany, a world leader in fuel cell technology. Specifically, it identifies and compares the drivers and barriers influencing the production and market penetration of privately-owned fuel cell electric passenger vehicles (FCEVs) and fuel cell electric buses (FCEBs) in public transit fleets. Using original data collected via a survey and 17 interviews, we elicited the opinions of experts to examine opportunities and obstacles in Germany from four perspectives: (i) the supply of vehicles (ii) refuelling infrastructure, (iii) demand for vehicles, and (iv) cross-cutting institutional issues. Findings indicate that despite multiple drivers, there are significant challenges hampering the growth of the hydrogen mobility market. Several are more pronounced in the passenger FCEV market. These include the supply and cost of production, the lack of German automakers producing FCEVs, the profitability and availability of refuelling stations, and low demand for vehicles. In light of these findings, we extract implications for international policymakers and future studies. This study provides a timely update on efforts to spur the deployment of hydrogen mobility in Germany and addresses the underrepresentation of studies examining both buses and passenger vehicles in tandem.

This study investigates the economic value added (EVA) of 18 major Chinese property companies from 2006 to 2012. We categorize the companies in two ways: 1) companies concentrating on property vs multi-functional companies and 2) state-owned enterprises (SOEs) vs privately-owned enterprises (POEs). We find that on average, the mainland property companies experienced a negative EVA during the period 2006–2012. This is due to the companies undertaking long-term projects, and the companies do not recognize capital gain from property appreciation as income. Hence the EVA of the companies is, in fact, understated. The results also reveal that POEs outperform SOEs in terms of EVA. This reflects the inefficiency of SOEs. This research has two important implications to investors. Firstly, besides looking at the EVA of the companies, investors should also understand the nature of businesses of the companies thoroughly. Secondly, investors investing in emerging markets like China should have a thorough understanding of their market characteristics. This study can act as a reference for future studies in EVA of property companies in other emerging economies in the world.

AbstractFe XIV 530.3 nm coronal emission line observations have been used for the estimation of the green solar corona rotation. A homogeneous data set, created from measurements of the world-wide coronagraphic network, has been examined with a help of correlation analysis to reveal the averaged synodic rotation period as a function of latitude and time over the epoch from 1947 to 1991.The values of the synodic rotation period obtained for this epoch for the whole range of latitudes and a latitude band ±30° are 27.52±0.12 days and 26.95±0.21 days, resp. A differential rotation of green solar corona, with local period maxima around ±60° and minimum of the rotation period at the equator, was confirmed. No clear cyclic variation of the rotation has been found for examinated epoch but some monotonic trends for some time intervals are presented.A detailed investigation of the original data and their correlation functions has shown that an existence of sufficiently reliable tracers is not evident for the whole set of examinated data. This should be taken into account in future more precise estimations of the green corona rotation period.
