A quantitative assessment of students’ experiences of studying music: a Spanish perspective on the European credit transfer system (ECTS)

The purpose of this investigation is to evaluate whether or not the allocation of time proposed in the Music Study Guide, adapted from the European Higher Education Area (EHEA) guidelines, is consistent and adequate for students with minimal musical knowledge. The report takes into account the importance of students’ previous knowledge and the relation this has to the time and effort expended by students in acquiring appropriate knowledge and skills. This is related also to the adequacy of the course specification to meet the demands of university study and the labour market. Results show that those students who enrolled at university without any previous musical knowledge are likely to experience significant difficulty in the acquisition of certain musical and professional competences. This highlights a need to reinforce the music curriculum, or establish zero-level courses, in order to enable such students to succeed in the subject.

Efficient Diastereo- and Enantioselective Synthesis of exo-Nitroprolinates by 1,3-Dipolar Cycloadditions Catalyzed by Chiral Phosphoramidite⋅Silver(I) Complexes

Chiral complexes formed by privileged phosphoramidites and silver triflate or silver benzoate are excellent catalysts for the general 1,3-dipolar cycloaddition between azomethine ylides generated from α-amino acid-derived imino esters and nitroalkenes affording with high dr the exo-cycloadducts 4,5-trans-2,5-cis-4-nitroprolinates in high ee at room temperature. In general, better results are obtained using silver rather than copper(II) complexes. In many cases the exo-cycloadducts can be obtained in enantiomerically pure form just after simple recrystallization. The mechanism and the justification of the experimentally observed stereodiscrimination of the process are supported by DFT calculations. These enantiomerically enriched exo-nitroprolinates can be used as reagents for the synthesis of nitropiperidines, by ester reduction and ring expansion, which are inhibitors of farnesyltransferase.

Representaciones de género en la publicidad de alimentos: un análisis de contenido

El análisis de contenido del mensaje mediático desde una perspectiva de género cuenta ya con una abundante bibliografía. En el caso de la publicidad, gran parte de los estudios realizados se han centrado en muestras genéricas de contenidos publicitarios o en aquella publicidad tradicionalmente asociada a uno u otro género. Sin embargo, pocos autores han analizado los contenidos de género de la publicidad relativa a productos de alimentación, a pesar de la estrecha relación entre estructuras de género y los procesos sociales de compra y preparación de alimentos. En este ámbito se sitúa, precisamente, nuestra investigación. Los principales resultados obtenidos muestran claras diferencias de género en las piezas publicitarias: tanto en términos de presencia cuantitativa como en la asignación de determinadas características.
