Towards a new conditionality? : The convergence of international development, nation brands and soft power in the British National Security Strategy

Nation brands are intended to act as vehicles for economic development. However, the role of the nation brands of developed countries in shaping the economic development of developing countries has not been explored to the same degree. Using the example of Britain’s 2010 National Security Strategy, this article argues that the two-decade long decline in conditional aid has been superseded by effor

Introduction : Why the Nordic region?

The Nordic region is much admired around the world, but how much of what we know about these countries has been shaped by their adoption of placebranding and public diplomacy techniques? This collection of academic articles and practitioner essays digs beneath the veneer of their branding and PD practices to investigate not just the best practice of how the Nordic region has successfully projected

Nondestructive Complete Mechanical Characterization of Zinc Blende and Wurtzite GaAs Nanowires Using Time-Resolved Pump− Probe Spectroscopy

We have developed and demonstrated an experimental method, based on the picosecond acoustics technique, to perform nondestructive complete mechanical characterization of nanowires, that is, the determination of the complete elasticity tensor. By means of femtosecond pump−probe spectroscopy, coherent acoustic phonons were generated in an ensemble of nanowires and their dynamics was resolved. Specif

Design for strong absorption in a nanowire array tandem solar cell

Semiconductor nanowires are a promising candidate for next-generation solar cells. However, the optical response of nanowires is, due to diffraction effects, complicated to optimize. Here, we optimize through optical modeling the absorption in a dual-junction nanowire-array solar cell in terms of the Shockley-Quessier detailed balance efficiency limit. We identify efficiency maxima that originate

Reactive dissolved organic carbon dynamics in a changing environment : Experimental evidence from soil and water

Löst organiskt kol (DOC) är den huvudsakliga formen av organiskt kol i vattenekosystem. Biologisk och fotokemisk nedbrytning av löst organiskt kol (DOC) är viktiga orsaker till utsläpp av växthusgaser från akvatiska ekosystem. Enligt studier vid olika platser på norra halvklotet så kan pågående klimatförändringar orsaka både ökningar och minskningar i total DOC-export från mark till vatten. Det fiDissolved organic carbon (DOC) is the major form of organic carbon in aquatic ecosystems. Biological and photochemical degradation of DOC are major causes of greenhouse gas emissions from aquatic ecosystems. In response to current changes in climate, studies at different northern-hemisphere locations have shown both increases and decreases in total DOC export from land to water. However, there is
