Symbolic meaning of local identity – A case study on Barcelona place brand representation

The core objective of this research process was to design an operational tool for place brand analysis. By modelling the emotional significance and the deeper-lying symbols associated to a specific place identity I expected to create a semiotic tool that could be applied, mutatis mutandis, on other similar place brands. As a field case study to develop the instrument, my choice of the research arena was Barcelona city, the capital of Catalonia Autonomous Community, Spain. Barcelona brand identity was approached in the line of the Chicago Urban Anthropology School. The research methods were designed according to the prescriptions of the urban anthropology, namely qualitative methods: in-depth interviews and discourse analysis. The final research outcome was a model summarizing a range of specific emotional values that support a place brand to position in the collective mindset and to assume a positively valued status and identity in the world order.

Identity, immigration, and prejudice in Europe: a recognition approach

Social identity is a double-edged sword. On the one hand, identifying with a social group is a prerequisite for the sharing of common norms and values, solidarity, and collective action. On the other hand, in-group identification often goes together with prejudice and discrimination. Today, these two sides of social identification underlie contradictory trends in the way European nations and European nationals relate to immigrants and immigration. Most European countries are becoming increasingly multicultural, and anti-discrimination laws have been adopted throughout the European Union, demonstrating a normative shift towards more social inclusion and tolerance. At the same time, racist and xenophobic attitudes still shape social relations, individual as well as collective behaviour (both informal and institutional), and political positions throughout Europe. The starting point for this chapter is Sanchez-Mazas' (2004) interactionist approach to the study of racism and xenophobia, which in turn builds on Axel Honneth's (1996) philosophical theory of recognition. In this view, the origin of attitudes towards immigrants cannot be located in one or the other group, but in a dynamic of mutual influence. Sanchez-Mazas' approach is used as a general framework into which we integrate social psychological approaches of prejudice and recent empirical findings examining minority-majority relations. We particularly focus on the role of national and European identities as antecedents of anti-immigrant attitudes held by national majorities. Minorities' reactions to denials of recognition are also examined. We conclude by delineating possible social and political responses to prejudice towards immigrants.

Identity formation in social networks websites: facebook and the interaction between young individuals in the cases of Slovenia and Catalonia

This paper lays down some theoretical framework for further research to be made on the subject of how identity of young Slovenian and Catalan users is forming within the social networking website Facebook. The author pursues his interest based on observation of how communicationand thus interaction between users is changing and how this is reflected in everyday practices. In so doing he tries to identify the connections between the individual, society and technology, asthese are more and more interwoven, and we cannot think one without the other in thecontemporary globalised world.

Role of the superior parietal lobules in letter-identity processing within strings: FMRI evidence from skilled and dyslexic readers.

Traditionally, the ventral occipito-temporal (vOT) area, but not the superior parietal lobules (SPLs), is thought as belonging to the neural system of visual word recognition. However, some dyslexic children who exhibit a visual attention span disorder - i.e. poor multi-element parallel processing - further show reduced SPLs activation when engaged in visual multi-element categorization tasks. We investigated whether these parietal regions further contribute to letter-identity processing within strings. Adult skilled readers and dyslexic participants with a visual attention span disorder were administered a letter-string comparison task under fMRI. Dyslexic adults were less accurate than skilled readers to detect letter identity substitutions within strings. In skilled readers, letter identity differs related to enhanced activation of the left vOT. However, specific neural responses were further found in the superior and inferior parietal regions, including the SPLs bilaterally. Two brain regions that are specifically related to substituted letter detection, the left SPL and the left vOT, were less activated in dyslexic participants. These findings suggest that the left SPL, like the left vOT, may contribute to letter string processing.

Desarrollo de Surrogates para la representación dinámica de la información digital

El volumen de información a la que un usuario tiene acceso en Internet esenorme. La representación de la misma ha ido evolucionando a lo largo del tiempo a lavez que se han establecido reglas, recomendaciones y directrices que conforman toda una ingeniería de diseño de interfaces con el propósito de mejorar la representación e interacción entre el usuario y el ordenador. Aún así, hay que ir evolucionando en la manera de tratar esta representación de la información ya que Internet es un espacio donde afloran, día tras día, nuevas tecnologías y servicios.De hecho, en este proyecto trataremos de mejorar la representación de lainformación mediante unos objetos que llamaremos surrogates o sustitutos. Como sunombre indica, estos sustitutos serán la representación de los elementos a reemplazar y cuya función podríamos calificar como de “puerta de enlace”. Dichos objetos estaránformados por elementos propios de la información a la que representan con el objetivo de que el usuario identifique de una manera más rápida y sencilla esta información.En definitiva, desarrollaremos unos surrogates que puedan ser usados endiferentes interfaces independientemente de la tecnología que se haya empleado para sudesarrollo y dotándolos de una serie de características y métodos con el fin de mejorar la interacción entre el usuario y la información.

Determination of Transmembrane Water Fluxes in Neurons Elicited by Glutamate Ionotropic Receptors and by the Cotransporters KCC2 and NKCC1: A Digital Holographic Microscopy Study.

Digital holographic microscopy (DHM) is a noninvasive optical imaging technique that provides quantitative phase images of living cells. In a recent study, we showed that the quantitative monitoring of the phase signal by DHM was a simple label-free method to study the effects of glutamate on neuronal optical responses (Pavillon et al., 2010). Here, we refine these observations and show that glutamate produces the following three distinct optical responses in mouse primary cortical neurons in culture, predominantly mediated by NMDA receptors: biphasic, reversible decrease (RD) and irreversible decrease (ID) responses. The shape and amplitude of the optical signal were not associated with a particular cellular phenotype but reflected the physiopathological status of neurons linked to the degree of NMDA activity. Thus, the biphasic, RD, and ID responses indicated, respectively, a low-level, a high-level, and an "excitotoxic" level of NMDA activation. Moreover, furosemide and bumetanide, two inhibitors of sodium-coupled and/or potassium-coupled chloride movement strongly modified the phase shift, suggesting an involvement of two neuronal cotransporters, NKCC1 (Na-K-Cl) and KCC2 (K-Cl) in the genesis of the optical signal. This observation is of particular interest since it shows that DHM is the first imaging technique able to monitor dynamically and in situ the activity of these cotransporters during physiological and/or pathological neuronal conditions.

A Typology of Identity-Related Crime

Identification is ever more important in the online world, and identity-related crime is a growing problem related to this. This new category of crime is not restricted to high-profile instances of identity 'theft' or identity fraud; it is wide-ranging and complex, ranging from identity deletion to unlawful identity creation and identity 'theft'. Commonly accepted definitions are lacking, thus blurring available statistics, and policies to combat this new crime are piecemeal at best. To assess the real nature and magnitude of identity-related crime, and to be able to discuss how it can be combated, identity-related crime should be understood in all its aspects. As a first key step, this article introduces a typology of identity-related crime, consisting of conceptual, technical and legal categories, that can be used as a comprehensive framework for future research, countermeasures and policies related to identity related crime.

Economia digital : una sortida per a múltiples sistemes comercials

Economia Digital: Una sortida per a múltiples sistemes comercials, és un treball de recerca que tracta sobre el comerç electrònic en tots els seus aspectes, partint d’un anàlisi teòric que estableix les bases d’aquest sistema comercial; seguit d’un estudi de dos casos concrets d’empreses que han introduït Internet en la seva activitat. Per una banda, una d’aquestes empreses, Destil·leries Julián Segarra, s’ha servit de les noves tecnologies, amb un ús publicitari, per tal de donar-se a conèixer però sense oferir la possibilitat de venda online. D’altra banda, Surfdevils S.L. no només utilitza els recursos que ofereix la xarxa de manera informativa, sinó que va més enllà i permet adquirir els seus productes mitjançant el seu espai web. A més es realitza un breu estudi sobre els hàbits de compra per Internet, mitjançant una enquesta efectuada a una mostra de la població.Tot aquest estudi, serveix per arribar a la conclusió que introduir el comerç electrònic dins del seu funcionament és rentable per a les empreses i beneficiós pels consumidors, ja que els ofereix la possibilitat d’adquirir els productes en un mercat més ampli, transparent i competitiu.

Dual-wavelength digital holographic microscopy with sub-nanometer axial accuracy

We present dual-wavelength Digital Holographic Microscopy (DHM) measurements on a certified 8.9 nm high Chromium thin step sample and demonstrate sub-nanometer axial accuracy. We introduce a modified DHM Reference Calibrated Hologram (RCH) reconstruction algorithm taking into account amplitude contributions. By combining this with a temporal averaging procedure and a specific dual-wavelength DHM arrangement, it is shown that specimen topography can be measured with an accuracy, defined as the axial standard deviation, reduced to at least 0.9 nm. Indeed, it is reported that averaging each of the two wavefronts recorded with real-time dual-wavelength DHM can provide up to 30% spatial noise reduction for the given configuration, thanks to their non-correlated nature. ©2008 COPYRIGHT SPIE
