Considered as a remedy to multiple problems that our world is facing, biofuels are nowadays promoted on a global scale. Despite this globalised approach, however, biofuels are heavily contested. Not only the social implications of biofuels are disputed and uncertain, particularly in countries of the global South, but also their environmental and economic rationales. Given these huge controversies, policies promoting biofuels would seem difficult to maintain. Yet, support for them has been surprisingly well established on the political agendas. With the aim of understanding this puzzle, this study asks how the dominant approach to biofuels has been sustained on a global level. In order to answer this question, the meanings and assumptions in biofuel discourses are explored through the lens of Maarten Hajer’s “argumentative” discourse analysis. Based on the existence of a “partnership for sustainable bioenergy” between the EU, Brazil and Mozambique, the study takes these three locations as case studies. The analysis reveals that various discursive strategies, including a particular problem construction and the use of two main story-lines, have played an important role in ensuring the permanence of the global approach to biofuels. Moreover, while the discourse of critics against biofuels demonstrates that there is room for contestation, the analysis finds that the opponents’ discourse largely fails to target the most salient justification for biofuels. A more effective strategy for critics would therefore be to also question the problem constructions underpinning this main justification in the global discourse.

Broadband access is a key factor for economic and social development. However, providing broadband to rural areas is not attractive to private telecommunications operators due its low or zero investment return. To deal with broadband provision in rural areas, different governance systems based on private and public cooperation have appeared. This paper not only identifies and defines public and private cooperation models but also assesses their impact on overcoming the digital divide in rural areas. The results show that public ownership infrastructure under private management policy has had positive effects on reducing the broadband digital divide and being applied to areas with higher digital divide; subsides to private operators providers only positive effects on reducing broadband digital divide; but public infrastructure with public management programs did not. The results, obtained using quasi-experimental methods, suggest the importance of incentives and control mechanisms in broadband universal service provision plans.

“La misión de Makonsa” un caso de ficción, basado en hechos reales, sobre una empresa que tiene que enfrentarse a la entrada de nuevos competidores en el mercado que amenazan la supervivencia de la compañía. Mario, que lleva un año como nuevo director general de Makonsa, tiene clara la estrategia a realizar: abandonar los productos de gama baja y tomar una posición competitiva en los productos de gama alta. Para lograrlo, la empresa deberá desarrollar una mayor flexibilidad, mejorar su capacidad de innovación e incrementar la calidad en el servicio. Sin embargo, la cultura organizativa -marcada por un bajo nivel de proactividad y deficiente comunicación- puede representar un fuerte freno a la implementación de la nueva estrategia. Frente a esta situación, Mario decide definir una misión que se cuelga en los despachos y salas de reuniones de la empresa.
