The role of space charge formation in the generation of thermally stimulated current (TSC) spectroscopy data for a model amorphous drug system

Thermally stimulated current (TSC) spectroscopy is attracting increasing attention as a means of materials characterization, particularly in terms of measuring slow relaxation processes in solid samples. However, wider use of the technique within the pharmaceutical field has been inhibited by difficulties associated with the interpretation of TSC data, particularly in terms of deconvoluting dipolar relaxation processes from charge distribution phenomena. Here, we present evidence that space charge and electrode contact effects may play a significant role in the generation of peaks that have thus far proved difficult to interpret. We also introduce the use of a stabilization temperature in order to control the space charge magnitude. We have studied amorphous indometacin as a model drug compound and have varied the measurement parameters (stabilization and polarization temperatures), interpreting the changes in spectral composition in terms of charge redistribution processes. More specifically, we suggested that charge drift and diffusion processes, charge injection from the electrodes and high activation energy charge redistribution processes may all contribute to the appearance of shoulders and 'spurious' peaks. We present recommendations for eliminating or reducing these effects that may allow more confident interpretation of TSC data.

The notion of space in the artistic language of Alfredo Jaar

Conceptual art and communicator role has influenced the work of Chilean architect Alfredo Jaar, which has been proposed report, with other codes [verbal and nonverbal], global events influencing contemporary society. His early training as an architect has driven innovation in the design of artistic space , using the message to convey to the viewer the reason for his work for more than three decades, highlights the artistic composition with various material resources whose purpose lies in conceptualizing various topics relevant in considering the role of artistic communication. Jaar’s style is the sum of his own life experience in relation to the contradictions of the world today, which is exposed and from the perspective of postmodernism from the exploitation of the notion of space as an open stage for visual and expressiveness beyond national borders, societies and cultures of the world.

‘‘Capital of Culture - you must be having a laugh!” Challenging the official rhetoric of Liverpool as the 2008 European cultural capital’

Major cultural events are increasingly seen by local stakeholders as important opportunities to stimulate urban regeneration, city branding and economic development. The European Capital of Culture programme is a prominent example. Since 1985 over thirty cities have hosted the title and today it remains a highly sought-after prize. This paper analyses competing interpretations of the success of Liverpool's hosting of the European Capital of Culture in 2008. It unpacks contrasting views of Liverpool08, from the official triumphant message of urban regeneration and economic renaissance to more critical analyses that problematise important elements of the event and its social and spatial impacts. In so doing, it challenges the hyperbole of culture-led transformation to reveal different geographies of culture, different cultural experiences and different socio-economic realities; it also offers an additional cultural reading of Liverpool in 2008. Through the example of Liverpool this paper shows how local culture is politicised, manipulated and sanitised in order to stimulate urban regeneration and construct a spatial re-branding of the city.

De grands événements culturels sont de plus en plus perçus par les rentiers locaux comme des opportunités importantes pour stimuler la régénération urbaine, produire la devise des villes et le développement économique. L'initiative La Capitale Européenne de la Culture est un exemple proéminent. Depuis 1985, plus de trente villes ont accueilli le titre et maintenant il reste un prix largement recherché. Cet article analyse des interprétations en concurrence du succès de l'accueil de Liverpool de la Capitale Européenne de la Culture en 2008. Il déballe des vues contrastées de Liverpool08, du message officiel et triomphal de la régénération urbaine et de la renaissance économique à des analyses plus critiques qui problématisent des éléments importants de l'événement et ses impacts sociaux et spatiaux. De cette façon, il conteste l'hyperbole de la transformation menée par la culture pour révéler des géographies différentes de la culture, des expériences différentes de la culture et des réalités socioéconomiques différentes; il offre aussi une interprétation culturelle différente de Liverpool en 2008. Au travers de l'exemple de Liverpool cet article montre comment la culture locale est politisée, manipulée et aseptisée pour stimuler la régénération urbaine et construire un relookage spatial de la ville.

Cada vez más, los inversores locales vean a los eventos culturales como oportunidades importantes para estimular regeneración urbana, el desarollo económico y la branding a una ciudad. El Capital Europeo de Cultura es un ejemplo prominente. Desde 1985, más que treinta ciudades han presentado el título y hoy sigue siendo un premio deseable. Este papel se analiza interpretaciones competitivos del éxito del Capital Europea de Cultura 2008 en Liverpool. Se deshace las perspectivas opuestas del Liverpool08, del mensaje triunfante de regeneración urbana y renacimiento económico, a analices críticos que problematizan elementos importantes del evento y sus impactos sociales y espaciales. Al hacer esto, se cuestiona el hipérbole de la transformación cultural para revelar geografías diferentes de cultura, experiencias culturales diferentes y realidades diferentes socio-económicas; también ofrece un entendimiento cultural adicional de Liverpool en el 2008. Através el ejemplo de Liverpool, este papel demuestra como la cultura local está politizada, manipulada, y desinfectado para estimular regeneración urbana y construir una nueva branding de la ciudad.

The rhetoric of acculturation: When integration means assimilation

Viewing traditional acculturation literature through a social constructionist lens, the present paper identifies a number of limitations with this research. A discourse analytic approach to acculturation is offered as a means of addressing some of these issues. Drawing on examples taken from British print media debate surrounding the issue of faith schooling in the UK, an analysis is presented which illustrates the manner in which, though optimally positioned within acculturative moral hierarchies directed towards the legitimization of both pro- and anti-faith schooling debates, integration rhetoric often conceals the (re-)production of a more implicit assimilationism. Findings are discussed in terms of their implications for hegemonically structured acculturative power relations. This exploratory analysis provides the basis for reflection on the benefits of a discursive approach to acculturation. Moreover, the dependence of integrationist discourse on a series of socio-spatial resources is considered and, following on from Dixon and Durrheim's (2000) discursive re-conceptualization of place-identity, is taken to signify the need for a more environmentally 'grounded' approach to acculturation.
