Catalan beauty and the transnational beast: Barcelona on screen

This article explores the case of Barcelona as paradigmatic global city in such transnational productions as Vicky Cristina Barcelona by Woody Allen (2008) and Biutiful by Alejandro Gonz��lez I����rritu (2010). Allen"s film shows the extreme dilution that national and linguistic identity undergoes under foreign eyes in its rendition of a"hip Barcelona" for tourists"invaded" by transnational subjects in search of bourgeois pleasures. Maybe in pursuit of a more"real" city, I����rritu"s Biutiful moves to the Barcelona of the immigrants and the undocumented, a transnational and paradoxical location inhabited by those who need to cross borders in order to survive. Through reference to the work of Manuel Castells, Saskia Sassen, Neil Smith and Michel De Certeau among others, we argue that neither of these representations of the city is more real or unreal than the other. In their drastically divergent ways, both films contribute their external perspectives to the imaginary construction of Barcelona as a fascinating global city and can be seen as a dyptich of a transnational Barcelona. Further, they contribute to the ongoing debate about the polarization between the local and the global, the construction of urban boarders inside cities through gentrification, the transformation of the places we (would like to) inhabit, and the translation of all these into visual terms.

Dynamics of flow: a nonlinear perspective

The aims of this study are to consider the experience of flow from a nonlinear dynamics perspective. The processes and temporal nature of intrinsic motivation and flow, would suggest that flow experiences fluctuate over time in a dynamical fashion. Thus it can be argued that the potential for chaos is strong. The sample was composed of 20 employees (both full and part time) recruited from a number of different organizations and work backgrounds. The Experience Sampling Method (ESM) was used for data collection. Once obtained the temporal series, they were subjected to various analyses proper to the com- plexity theory (Visual Recurrence Analysis and Surrogate Data Analysis). Results showed that in 80% of the cases, flow presented a chaotic dynamic, in that, flow experiences delineated a complex dynamic whose patterns of change were not easy to predict. Implications of the study, its limitations and future research are discussed.

Superioridad del procesamiento de los rasgos globales en funci��n de la densidad estimular

Se ha sometido a comprobaci��n emp��rica la hip��tesis de la precedencia global (Navon, 1977, 1981a, 1983), seg��n la cual el analisis de los rasgos globales de una configuraci��n visual precede temporalmente al de los locales. Se ha demostrado que la naturaleza del estimulo es un factor que modula la aparici��n de primacia global cuando el material manejado es verbal y altamente familiar, pero no cuando es visoespacial y novedoso para el sujeto. Sin embargo, [os presentes experitnentos han sugerido que el efecto del grado de novedad del estimulo se ve anulado cuando se manipula el n��mero de elementos locales que cornponen la imagen visual. Se ha obtenido el efecto tipico de precedencia global, independienternente de la naturaleza del estimulo, cuando la configuracidn estuba formada por muchos elementos locales (7x6). Para est��mulos con 5x4 constituyentes se ha obtenido el efecto contrario, es decir, la informaci��n local era analizada con mayor rapidez que la global. Los resultados han sido explicados en base al agrupamiento de 1os rasgos locales de la imagen visual.

Percentage of nonoverlapping corrected data

The present study proposes a modification in one of the most frequently applied effect size procedures in single-case data analysis the percent of nonoverlapping data. In contrast to other techniques, the calculus and interpretation of this procedure is straightforward and it can be easily complemented by visual inspection of the graphed data. Although the percent of nonoverlapping data has been found to perform reasonably well in N = 1 data, the magnitude of effect estimates it yields can be distorted by trend and autocorrelation. Therefore, the data correction procedure focuses on removing the baseline trend from data prior to estimating the change produced in the behavior due to intervention. A simulation study is carried out in order to compare the original and the modified procedures in several experimental conditions. The results suggest that the new proposal is unaffected by trend and autocorrelation and can be used in case of unstable baselines and sequentially related measurements.

Choosing among techniques for quantifying single-case intervention effectiveness

If single case experimental designs are to be used to establish guidelines for evidence-based interventions in clinical and educational settings, numerical values that reflect treatment effect sizes are required. The present study compares four recently developed procedures for quantifying the magnitude of intervention effect using data with known characteristics. Monte Carlo methods were used to generate AB designs data with potential confounding variables (serial dependence, linear and curvilinear trend, and heteroscedasticity between phases) and two types of treatment effect (level and slope change). The results suggest that data features are important for choosing the appropriate procedure and, thus, inspecting the graphed data visually is a necessary initial stage. In the presence of serial dependence or a change in data variability, the Nonoverlap of All Pairs (NAP) and the Slope and Level Change (SLC) were the only techniques of the four examined that performed adequately. Introducing a data correction step in NAP renders it unaffected by linear trend, as is also the case for the Percentage of Nonoverlapping Corrected Data and SLC. The performance of these techniques indicates that professionals" judgments concerning treatment effectiveness can be readily complemented by both visual and statistical analyses. A flowchart to guide selection of techniques according to the data characteristics identified by visual inspection is provided.
