Global movements, national grievances. Mobilizing for “real democracy” and social justice

In the ashes of political and socio-economic collapse, social movements sometimes rise like a phoenix. Little more than a year has passed since the Tunisian uprisings, the spark that ignited a series of “mobilizations of the indignant” that spread like wildfire around the world. Many observers have reported on these unprecedented global protests. They have portrayed citizens who declare feeling marginalized if not scapegoated, and who reject the increasing inequalities between rich and poor, the declining mobility of most, and the “disclassment” of many. They have shown, as well, massive protests against governments and politicians that are perceived as indifferent at best, duplicitous at worst, and in any event as blatantly closed to popular concerns. Many journalists have indeed asked what took so long for people to protest given this fatal combination. For the social scientist, however, the questions of who, why and how mobilizes are not so simple. There are specific problematics of mediation between structure, culture and individual or collective agency that need to be addressed.

A Real-Time Sliding Mode Control for a Wind Energy System Based on a Doubly Fed Induction Generator

In this paper, a real time sliding mode control scheme for a variable speed wind turbine that incorporates a doubly feed induction generator is described. In this design, the so-called vector control theory is applied, in order to simplify the system electrical equations. The proposed control scheme involves a low computational cost and therefore can be implemented in real-time applications using a low cost Digital Signal Processor (DSP). The stability analysis of the proposed sliding mode controller under disturbances and parameter uncertainties is provided using the Lyapunov stability theory. A new experimental platform has been designed and constructed in order to analyze the real-time performance of the proposed controller in a real system. Finally, the experimental validation carried out in the experimental platform shows; on the one hand that the proposed controller provides high-performance dynamic characteristics, and on the other hand that this scheme is robust with respect to the uncertainties that usually appear in the real systems.

Incidental Memory of Younger and Older Adults for Objects Encountered in a Real World Context

Effects of context on the perception of, and incidental memory for, real-world objects have predominantly been investigated in younger individuals, under conditions involving a single static viewpoint. We examined the effects of prior object context and object familiarity on both older and younger adults' incidental memory for real objects encountered while they traversed a conference room. Recognition memory for context-typical and context-atypical objects was compared with a third group of unfamiliar objects that were not readily named and that had no strongly associated context. Both older and younger adults demonstrated a typicality effect, showing significantly lower 2-alternative-forced-choice recognition of context-typical than context-atypical objects; for these objects, the recognition of older adults either significantly exceeded, or numerically surpassed, that of younger adults. Testing-awareness elevated recognition but did not interact with age or with object type. Older adults showed significantly higher recognition for context-atypical objects than for unfamiliar objects that had no prior strongly associated context. The observation of a typicality effect in both age groups is consistent with preserved semantic schemata processing in aging. The incidental recognition advantage of older over younger adults for the context-typical and context-atypical objects may reflect aging-related differences in goal-related processing, with older adults under comparatively more novel circumstances being more likely to direct their attention to the external environment, or age-related differences in top-down effortful distraction regulation, with older individuals' attention more readily captured by salient objects in the environment. Older adults' reduced recognition of unfamiliar objects compared to context-atypical objects may reflect possible age differences in contextually driven expectancy violations. The latter finding underscores the theoretical and methodological value of including a third type of objects-that are comparatively neutral with respect to their contextual associations-to help differentiate between contextual integration effects (for schema-consistent objects) and expectancy violations (for schema-inconsistent objects).

¿Encargó Braulio de Zaragoza a Eugenio de Toledo que compusiera una Misa de San Millán?: para una interpretación de «Vita Emiliani», 3, 5-10

[EN] What is Braulio asking from Eugenius in this passage: that he requires a Mass to be celebrated (where?) in honour of San Millán, or that Eugenius himself writes the Mass, or, simply, some parts or prayers for it? Firstly, translations and interpretations provided by scholars to date are checked and criticized; then an interpretation of the passage is proposed, being based on textual criticism approaches, on the work context and on the cultural environment in which this work takes place.

La «Vita Emiliani» de Braulio de Zaragoza: el autor, la cronología y los motivos para su redacción

[ES] En este trabajo se pretende realizar un estudio histórico-filológico de algunos puntos centrales de 'Vita Emiliani' y que responden a las preguntas siguientes: ¿Por qué Braulio de Zaragoza, uno de los obispos más importantes de la Hispania visigótica, escribe la vida de San Millán, un eremita, un santo un tanto singular, con asomos polémicos y aristas molestas? ¿Qué vinculación tenía la familia altoeclesiástica de Braulio con el centro monástico de San Millán? ¿Por qué se eligio a Braulio para escribir la 'Vita'? ¿cCómo reaccionó Braulio ante esa solicitud? ¿Pretendió Braulio dibujar un santo nacional para la Hispania visigótica? ¿Quería Braulio hacer de Millán un modelo ortodoxo frente a los arrianos y/o priscilianistas? ¿Se escribió 'Vita Emiliani' con una finalidad y textura apologética? ¿Nació 'V. Em.' para una función y uso litúrgico? ¿Qué clase de público leería 'V. Em.'? Además, en los dos primeros puntos del trabajo se intenta precisar la fecha de composición de 'V. Em.' mediante la discusión de los datos pertinentes, y se da un sucinto panorama de la historia de su autoría.

¿Uno o dos frunimianos en 'Vita Emiliani' y cartas de Braulio de Zaragoza?

[EN] We try to prove, with arguments taken from the texts, that the person named "Fruinianus", to whom Braulio de Saragossa addresses his letters XIII and XIV in his epistolary, is the same Frunimianus as the one from the introductory letter to 'Vita Emiliani', that is, Braulio's brother.

Valuation of Wind Energy Projects: A Real Options Approach

We address the valuation of an operating wind farm and the finite-lived option to invest in it under different reward/support schemes: a constant feed-in tariff, a premium on top of the electricity market price (either a fixed premium or a variable subsidy such as a renewable obligation certificate or ROC), and a transitory subsidy, among others. Futures contracts on electricity with ever longer maturities enable market-based valuations to be undertaken. The model considers up to three sources of uncertainty: the electricity price, the level of wind generation, and the certificate (ROC) price where appropriate. When analytical solutions are lacking, we resort to a trinomial lattice combined with Monte Carlo simulation; we also use a two-dimensional binomial lattice when uncertainty in the ROC price is considered. Our data set refers to the UK. The numerical results show the impact of several factors involved in the decision to invest: the subsidy per MWh generated, the initial lump-sum subsidy, the maturity of the investment option, and electricity price volatility. Different combinations of variables can help bring forward investments in wind generation. One-off policies, e.g., a transitory initial subsidy, seem to have a stronger effect than a fixed premium per MWh produced.
