LA EDUCACIÓN PARA UNA CIUDADANÍA PELIGROSA

El concepto de educación pública se encuentra bajo la influencia de las imágenes dominantes y dominadoras más que en la autentica comprensión de la complejidad de las realidades diarias del aula. Basándose en los trabajos de Debord y Foucault, especialmente en sus visiones libertarias y antiestáticas del poder, de la autoridad y del control en la sociedad contemporánea, este artículo examina cómo el control social se ejerce a través de las imágenes dominantes y una mezcla de vigilancia y espectáculo. En respuesta a estas condiciones, desarrollamos el concepto de «ciudadanía peligrosa». Reclamamos que las condiciones contemporáneas requieren de una Educación para la Ciudadanía antiopresiva, que se tome en serio las desigualdades sociales y económicas, y la opresión fruto del capitalismo neoliberal que restringe las posibilidades antiopresivas y establece unas pedagogías oficiales y sancionadoras. El poder pedagógico de la ciudadanía peligrosa reside: 1) en la capacidad de alentar al alumnado y al profesorado sobre las implicaciones de su propia enseñanza y aprendizaje; 2) en visualizar una educación focalizada en la libertad y en la democracia, y 3) en interrogar y deconstruir sus bienintencionadas complicidades con el sistema a partir de prácticas y textos culturales, especialmente para relacionar las condiciones opresivas con las prácticas culturales del mismo estilo, y viceversaConceptualizations of public schooling rest upon the influence of dominant and dominating images rather than on more authentic understandings of the complex realities of classroom life. Drawing upon the work of both Debord and Foucault, particularly their libertarian and anti-statist visions of power, authority, and control in contemporary society, this article examines how social control is exercised via controlling images and a merger of surveillance and spectacle. In response to these conditions we develop the concept of “dangerous citizenship.” We argue that contemporary conditions demand an antioppressive citizenship education, one that takes seriously social and economic inequalities and oppression that result from neoliberal capitalism and that builds upon the antioppressive possibilities of established and offi cially sanctioned pedagogies. The pedagogical power dangerous citizenship resides in its capacity to encourage students and educators to challenge the implications of their own education/instruction, to envision an education that is free and democratic to the core, and to interrogate and uncover their own well-intentioned complicity in the conditions within which various cultural texts and practices appear, especially to the extent that oppressive conditions create oppressive cultural practices, and vicevers

Using conversational data to determine lexical frequency in British Sign Language: The influence of text type

This paper presents findings from an objective lexical frequency study in British Sign Language (BSL) based on 24,823 tokens collected as part of the BSL Corpus Project. The BSL study is only the fourth objective frequency study involving sign languages to be reported and is also the first study for any sign language to be based on entirely on spontaneous conversational data. When compared to previous frequency studies (both spoken and signed), some similarities can be observed although differences that may be attributed to text type are also recorded. When compared with subjective frequency ratings collected for BSL, a positive relationship is reported (similar to what has been observed for spoken languages). This is in contrast to a previous study which suggested a much weaker relationship between the two; however, this conclusion was based on a frequency count derived from narratives. These differences highlight the importance of using frequency measures derived from natural and spontaneous data, an opinion that has been emphasised in the spoken language literature

Semantic activation in LSD: evidence from picture naming

Lysergic acid diethylamide (LSD) is a classic psychedelic drug that alters cognition in a characteristic way. It has been suggested that psychedelics expand the breadth of cognition via actions on the central nervous system. Previous work has shown changes in semantic processing under psilocybin (a related psychedelic to LSD) that are consistent with an increased spread of semantic activation. The present study investigates this further using a picture-naming task and the psychedelic, LSD. Ten participants completed the task under placebo and LSD. Results revealed significant effects of LSD on accuracy and error correction that were consistent with an increased spread of semantic activation under LSD. These results are consistent with a generalised “entropic” effect on the mind. We suggest incorporating direct neuroimaging measures in future studies, and to employ more naturalistic measures of semantic processing that may enhance ecological validity

Lifetime determination of excited states in Cd-106

Two separate experiments using the Differential Decay Curve Method have been performed to extract mean lifetimes of excited states in 106 Cd. The inedium-spin states of interest were populated by the Mo-98(C-12, 4n) Cd-106 reaction performed at the Wright Nuclear Structure Lab., Yale University. From this experiment, two isomeric state mean lifetimes have been deduced. The low-lying states were populated by the Mo-96(C-13, 3n)Cd-106 reaction performed at the Institut fur Kernphysik, Universitat zu Koln. The mean lifetime of the I-pi = 2(1)(+) state was deduced, tentatively, as 16.4(9) ps. This value differs from the previously accepted literature value from Coulomb excitation of 10.43(9) ps

Exact Bayesian curve fitting and signal segmentation.

We consider regression models where the underlying functional relationship between the response and the explanatory variable is modeled as independent linear regressions on disjoint segments. We present an algorithm for perfect simulation from the posterior distribution of such a model, even allowing for an unknown number of segments and an unknown model order for the linear regressions within each segment. The algorithm is simple, can scale well to large data sets, and avoids the problem of diagnosing convergence that is present with Monte Carlo Markov Chain (MCMC) approaches to this problem. We demonstrate our algorithm on standard denoising problems, on a piecewise constant AR model, and on a speech segmentation problem
