A descriptive, easy to implement approach for the self sensing operation of permanent magnet synchronous machines (PMSM) is presented in this paper. Position and speed identification is performed by solving a nonlinear equation system with a simple, real-time capable algorithm. The approach considers nonlinear magnetic effects by means of flux linkage maps and thus provides reliable position and speed identification in the full speed and torque operating range for stationary and dynamic operation. An experimental proof of functionality is presented.

International trade is one of the key mechanisms for the diffusion of energy-efficient technologies. Yet, little is known about how environmental regulations, such as those aimed at increasing energy efficiency, affect international trade in environmental or green goods. This paper studies the case of the Energy Performance of Buildings Directive, which was adopted in 2010 by the European Union. We use pooled ordinary least square and Poisson estimators to empirically test whether and how differences in implementation affected trade in relevant products. We find strong evidence that those EU member states that implemented the directive to a large extent had substantially higher import volumes of environmental products at possibly lower prices. For certain environmental products, exports equally increased. Our paper is the first to show that the implementation of environmental regulation can spur international trade in environmental products. These findings can provide important lessons for Asia and help transform it into a more competitive, prosperous, and greener region.

Sports sponsorship is a core element of brand communication and one of the most effective and demanded tools in marketing. In the context of football, jersey sponsorship agreements dramatically increased over the last decade in terms of deal volume. Another current brand communication trend is the brand strategy of placing brands into entertainment media, especially in video games, so called in-game advertising (IGA). Against that background, the current study addresses the short-term effects of IGA on consumer’s implicit and explicit brand knowledge after the sponsor brand has been exposed in a video game. The findings of the laboratory research showed that the IGA exposure of sponsor brands, which was simulated in the current study as a virtual consumer-brand interaction within a playfully football game, was primarily effective to enhance brand-related associations on an implicit level, but not on an explicit level.

Currently, the European Union is negotiating an free trade agreement, called Economic Partnership Agreement (EPA), with Caribbean countries as part of the Cotonou Agreement between the European Union and African, Caribbean and Pacific countries. The paper empirically assesses the impact of the proposed EPA on trade flows and government revenue for Caribbean countries. The results indicate that the decline in import duties due to the preferential tariff elimination might be of some cause for concern in a number of countries, and that complementary fiscal and economic policies have to be implemented before or at the time the EPA comes into force.
