La mayoría de los estudios realizados sobre el tratamiento de género en la publicidad audiovisual se ciñen al formato convencional. Los nuevos formatos no se adecuan siempre a estos patrones. Con este fin, se ha elaborado un protocolo de análisis para estudiar la estructura del brand-placement, como forma no convencional de publicidad, en temas de género en la ficción española. Esta herramienta ha sido sometida a rigurosos controles de fiabilidad y validez con el ánimo de garantizar la confiabilidad y rigurosidad científica de las mismas, tanto en su composición como en su aplicación.

Electron donor-acceptor (EDA) interactions are widely involved in chemistry and their understanding is essential to design new technological applications in a variety of fields ranging from material sciences and chemical engineering to medicine. In this work, we study EDA complexes of carbon dioxide with ketones using several ab initio and Density Functional Theory methods. Energy contributions to the interaction energy have been analyzed in detail using both variational and perturbational treatments. Dispersion energy has been shown to play a key role in explaining the high stability of a non-conventional structure, which can roughly be described by a cooperative EDA interaction.

This paper shows the increasing trend of Spanish young people towards non-conventional mechanisms of political expression, in a crisis context which has reduced its reliance on traditional political actors. As an alternative to bipartisanship, political participation moves towards increased interest and attention to new players, such as emergent political parties. Using a covariance structural model, factors such as political activism, awareness and understanding of country problems, and trust in the political system, are explored in order to explain an electoral behavior that is undergoing deep changes.

The crisis affecting European Union, and especially Mediterranean countries, is both an economic and a political crisis. In a broad sense, we can look at the crisis as the result of an internal crisis of the neoliberal model, exacerbating the perceived subordination of politics to the economy, and therefore the deficit of legitimacy and involvement that characterizes both European and national institutions. The decline in support for traditional political organizations and reduction of conventional political participation is accompanied by a process of reinvention of politics, which takes form in grass-root, non conventional participation. New political actors challenge economic and political institution and claim for a renewal of democracy and for a new relation between economy and politics. The article, after comparing steps and dimension of crisis, explores the characteristics of anti- austerity movements in Spain and in Italy, analyzing differences and similarities. Finally, we locate the movilization occurred in these two countries within the context of the global cycles of protest.

In this review, we consider the main processes for the asymmetric transfer hydrogenation of ketones from 2008 up today. The most effective organometallic compounds (derived from Ru, Rh, Ir, Fe, Os, Ni, Co, and Re) and chiral ligands (derived from amino alcohols, diamines, sulfur- and phosphorus-containing compounds, as well as heterocyclic systems) will be shown paying special attention to functionalized substrates, tandem reactions, processes under non-conventional conditions, supported catalysts, dynamic kinetic resolutions, the use of water as a green solvent, theoretical and experimental studies on reaction mechanisms, enzymatic processes, and finally applications to the total synthesis of biologically active organic molecules.
