Programas iconográficos en "La piel que habito" (Almodóvar, 2011)

Como viene siendo habitual en las últimas películas de Pedro Almodóvar, las imágenes de La piel que habito (2011) se organizan en programas iconográficos que en este caso emanan de operaciones “trans” realizadas tanto en el cuerpo (transexualidad, transgénesis y trasplante), como en el texto (transtextualidad). El presente trabajo se ocupa de la genealogía y formalización de dichos programas así como de cuestiones teóricas surgidas a lo largo del desarrollo de este estudio –la relación entre cuerpo e identidad o el llamado muro de pantallas, entre otras–, de indudable calado en el filme.

Preparation of nanoparticulate metal catalysts in porous supports using an ionic liquid route; hydrogenation and C-C coupling

Aerogels containing palladium metal nanoparticles were prepared using an ionic liquid route and tested for activity towards hydrogenation and Heck C-C coupling reactions. (C) 2003 Elsevier B.V. All rights reserved.

Chemoenzymatic synthesis of chiral 4,4 '-bipyridyls and their metal-organic frameworks

The first enantiopure 4,4'-bipyridyls, 6, 8, and 9 have been prepared in four or five steps via bacterial dioxygenase-catalysed cis-dihydroxylation of 4-chloroquinoline 1 and C-C coupling; ligands 6 and 9 are found to be effective building blocks for the preparation of chiral metal-organic frameworks as demonstrated with the rational synthesis of two pillared-grid structures [Zn-2(fumarate)(2)(L)], which exhibit interesting structural and dynamic aspects.

A low molecular weight hydro and organogelator derived from an isohexide and sol-gel transcription of the alcogel

Heating 2,5-di-O-methanesulfonyl-1,4:3,6-dianhydro-D-sorbitol (1) in a range of solvents led to the formation of a gel state at low concentrations. 1 was found to gel aromatics, alcohols and water. The structure of 1 in the solid state was solved by single crystal X-ray crystallography; no strong hydrogen bonds or associated solvents were found in the crystal. Electron micrographs revealed the morphology of the gels to be predominantly rod-like. The ethanol alcogel was used to template silica by sol-gel transcription.

The Co-Entrapment of a Homogeneous Catalyst and an Ionic Liquid by a Sol-gel Method: Recyclable Ionogel Hydrogenation Catalysts

Molecular hydrogenation catalysts have been co-entrapped with the ionic liquid [Bmim]NTf(2) inside a silica matrix by a sot-gel method. These catalytic ionogels have been compared to simple catalyst-doped glasses, the parent homogeneous catalysts, commercial heterogeneous catalysts, and Rh-doped mesoporous silica. The most active ionogel has been characterised by transmission electron microscopy, X-ray photoelectron spectroscopy, and solid state NMR before and after catalysis. The ionogel catalysts were found to be remarkably active, recyclable and resistant to chemical change.

Accounting and business students' approaches to learning: A longitudinal study

This study reports the results of an investigation into the learning approaches of undergraduate accounting and business students from three universities in Ireland who were exposed to a learning environment, namely the case study method, which aimed to encourage a deep approach to learning. In order to assess the effectiveness of the intervention, the ASSIST research instrument was used to investigate changes in students’ approaches to learning over time. Consistent with previous research, this study considers whether gender is related to students’ approaches to learning over time and if there are differences between students majoring in accounting or business in their approaches to learning. The results of the study indicate that the case study intervention was successful in some respects. However, contrary to expectations, an overall statistically significant increase in students’ surface approach to learning was found. Additionally, it is reported that changes in students’ approaches to learning over time are not associated with gender or degree program. The results of this study offer insights to accounting educators developing educational interventions to encourage deep approaches to learning.

A Review of an Initiative to Introduce a Short Ethics Component into a Non-Ethics Course at a U.K. University

This paper discusses the introduction of a short ethics component into a first-year undergraduate accounting information systems course at a UK university. The influence of this ethics component on students’ ethical perceptions – where ethical perceptions are represented by the extent to which students’ conclusions regarding unethical actions coincide with those of experts in the field – is then assessed using computer-based scenarios to represent seven categories of ethical norms. The ethical perceptions in each of the scenarios are then statistically compared between two groups of students, namely those who have studied the ethics component and those who have not. Results indicate no significant difference in ethical perceptions between the two groups across all of the ethical norms. Possible explanations for this result are discussed and implications for future ethics teaching are considered.
