Over the past 30 years, developed economies' approaches to supporting growth have focused on competitiveness, entrepreneurship and innovation to varying degrees. However, following the credit crisis and global recession in 2008 there has been demand for an updated narrative of growth based on the emergence of new industries. This paper provides a brief review of the available literature on how governments in leading economies can support new industries to emerge to the benefit of their national economy, discusses a number of issues for governments trying to support emerging industries, provides a framework of activities which governments considering this type of intervention should consider, and discusses the case of the regenerative medicine industry in the UK using the framework.

The taxicab provides a significant contribution to the accessibility of a city and provides a wide range of services across many social groups. Considering the role of the taxi this books examines the impacts that the mode currently has, and how it may continue to develop in the provision of access within the city.

Does environmental regulation impair international competitiveness of pollution-intensive industries to the extent that they relocate to countries with less stringent regulation, turning those countries into "pollution havens"? We test this hypothesis using panel data on outward foreign direct investment (FDI) flows of various industries in the German manufacturing sector and account for several econometric issues that have been ignored in previous studies. Most importantly, we demonstrate that externalities associated with FDI agglomeration can bias estimates away from finding a pollution haven effect if omitted from the analysis. We include the stock of inward FDI as a proxy for agglomeration and employ a GMM estimator to control for endogenous time-varying determinants of FDI flows. Furthermore, we propose a difference estimator based on the least polluting industry to break the possible correlation between environmental regulatory stringency and unobservable attributes of FDI recipients in the cross-section. When accounting for these issues we find robust evidence of a pollution haven effect for the chemical industry. © 2008 Springer Science+Business Media B.V.

In the manufacture of granular NPK fertilizer the product is cooled before packaging and storage in moisture-proof bags. It has been shown that the temperature of the fertilizer prior to packing is significant in that at high temperatures, drying of the granules takes place in the bag which causes an increase in the humidity of the air surrounding the granules and thus an increase in moisture content at the granule - granule interface. This surface moisture was shown to increase the likelihood of agglomeration in the fertilizer by a capillary adhesion/unconfined yield stress model. An iterative model was set up to establish conditions that would prevent drying occurring, which takes into account fertilizer drying rate, fertilizer cooling rate cooling rate and the effect of coating oils on the drying mechanism.
