Nomadic identities and socio-spatial competence: making sense of post-smoking selves

The reconstruction of smoking as an unhealthy practice has given rise to a discursive field in which some people shy away from smoking identities that are tainted with the attendant notions of dirt and disgust and also from overt external control over individual behaviour. In many cases individuals demonstrate social competence by quitting smoking. Social and secret smokers challenge both binary understandings of smoking identities (smoker/non-smoker) as well as the addiction model that is prevalent in explaining smoking. Social and secret smoking are conceptualised as nomadic identities that are situationally constructed and deconstructed, but always with the potential to slip into one or other identity more permanently. While these identities remain ambivalent and appear to manage their own risks, they provide us with a window into the body as a potentiality rather than a problem and thus move us beyond a compliance/resistance schema. The paper concludes that ex-, secret and social smoking involve different types of socio-spatial competence and, in order to make sense of this, we utilise both Foucauldian and Deleuzo-Guattarian frameworks.     

Partisan Efficiency in an Open-Rule Setting: The Amending Process in the U.S. Senate, 1865–1945

Given significant differences between the House and Senate's amending processes, one would anticipate the Senate majority party to be far less successful when voting on the floor. However, recent work has demonstrated that majority party success on the Senate floor is remarkably similar to the House. We argue that an overlooked explanation for majority party success stems from its ability to control intra-party amending activity through coordination between members of the majority party. Utilizing a new data set consisting of all amendments receiving recorded roll call votes in the Senate from 1865–1945, we demonstrate that majority party extremists refrain from offering amendments despite the relative open-floor setting. Nevertheless, chamber majorities cannot restrict minority legislators from offering amendments designed to force them to cast uncomfortable votes and delay the legislative process.     

MakingGüeras: Selling white identities on late-night Mexican television

This article examines discourses of whiteness and color in Mexico through a discussion of White Secret, a widely available skin-lightening cosmetic product. In an analysis of a televised infomercial advertising the product, we examine contextualizations of whiteness in Mexico, as figured through the product's representations of light-skinned female bodies and advanced cosmetic technology. We consider the ways that White Secret can speak to broader conceptualizations of whiteness and identity and, furthermore, argue that such an engagement points to the need to interrogate the geographical and epistemological limits of current understandings of whiteness based in Anglo-American and Latin-American contexts.

Creando güeras: La venta de identidades blancas en la televisión Mexicana de media noche En este artículo, hacemos un análisis sobre los discursos de ‘blancura’ y de color con respecto a la población en México a través de una discusión sobre ‘White Secret’, un producto cosmético para aclarar la piel que es muy disponible en México. Por un análisis de un ‘info-nuncio’ que sale por la televisión anunciando el producto ‘White Secret’, exploramos los entretejemientos de la construcción de blancura en México y como este ‘info-nuncio’ manipula imágenes de los cuerpos de güeras (mujeres de piel clara) y tecnología cosmética avanzada. Reflexionamos acerca de las maneras que el producto ‘White Secret’ pueda hablar a concepciones más amplias sobre la construcción de identidad y blancura y además, discutimos que tal exploración indica la necesidad de interrogar los limites epistemológicos y geográficos de la comprensión actual de la construcción de blancura basados en los contextos Latino Americanos y Anglo Americanos.     

AN ECONOMIC INTERPRETATION OF KUHN'S DUAL FOR THE STEINER-WEBER PROBLEM A NOTE*

In this paper, we given an economic interpretation of Kuhn's dual of the Steiner-Weber problem. It depends essentially on the notion that different transportation systems arerelevant for the primal and the dual. Moreover, the Euclidean metric underlies the interpretation of the primal, the block one that of the dual.     

Occupational neurotoxicity and movement disorders: a historical perspective

It is shown that while metal toxicity has been known to be associated with risks to the health of miners and other workers for over a thousand years generally little was done before the 19th century to enquire into the relationship between lead, mercury, and manganese and neurological movement disorders. Reasons for this are suggested.
