Fragile scenes,fractured communities: Tunisian Metal and sceneness

The paper proposes a reshaping of musical and cultural scene as a framework for the study of youth cultures. Developed in the ambit of post-subcultural theories, scene well represents the forces and flaws of such a category: high dynamism and ethnographic richness on one side; vagueness on the other. In order to reduce such vagueness, I conceptualise sceneness, intended as the substance of scenes, their density in networking and infrastructures. I use Arjun Appadurai’s concepts of locality and neighbourhoods to signify, respectively, sceneness and the actual scenes: in this way I redefine scene as a fragile construct that needs to be ritually revived, and that can work as a context for the development of new meanings and social groups. This implies conflict as a central element of scenes, one which can lead them to disequilibrium and disappearance. Such a redefinition is helpful for analysing fragile scenes which struggle to exist in troubled contexts, such as poor and hostile social environments. I provide, as an example, my ethnographic research on Metal in Tunisia. Caught between idealised images of community and an actual community which was conflictual and ‘fractured’, the Tunisian Metal scene lives a precarious existence threatened by material constraints and cultural marginality.     

Unfolding female quiet in wargames: gender bias in Metal Gear Solid V: The Phantom Pain from representation to gameplay

This article investigates the cultural mediatization of the relationship between gender and war by looking at the representation and agency of female presence in one of the most popular sagas in video games: Metal Gear Solid. We have specifically focused on the last chapter of the series, Metal Gear Solid V (MGS5) by putting under scrutiny the character of Quiet. The analysis draws upon the rich theoretical corpus of feminist film studies, with reference to two main concepts: the “visual pleasure” by Laura Mulvey and the “female voice” by Kaja Silverman. These analytic tools are employed in order to scrutinize both the visual representation and the design of the game. We argue that MGS5 is a relevant instance of a large part of gaming production that develops a war imagery characterized by (a) the exploitation of women and (b) an employment of female body as a tool to fulfill the visual pleasure of the male gaze. The figure of Quiet, with the oversexualization of her body and the deprivation of her voice, is particularly telling in this respect. Our analysis aims to identify effective solutions in order to think about more inclusive digital games able to address conflictual issues without surrendering to sexism.

Regression calibration for logistic regression with multiple surrogates for one exposure

Methods have been developed by several authors to address the problem of bias in regression coefficients due to errors in exposure measurement. These approaches typically assume that there is one surrogate for each exposure. Occupational exposures are quite complex and are often described by characteristics of the workplace and the amount of time that one has worked in a particular area. In this setting, there are several surrogates which are used to define an individual's exposure. To analyze this type of data, regression calibration methodology is extended to adjust the estimates of exposure-response associations for the bias and additional uncertainty due to exposure measurement error from multiple surrogates. The health outcome is assumed to be binary and related to the quantitative measure of exposure by a logistic link function. The model for the conditional mean of the quantitative exposure measurement in relation to job characteristics is assumed to be linear. This approach is applied to a cross-sectional epidemiologic study of lung function in relation to metal working fluid exposure and the corresponding exposure assessment study with quantitative measurements from personal monitors. A simulation study investigates the performance of the proposed estimator for various values of the baseline prevalence of disease, exposure effect and measurement error variance. The efficiency of the proposed estimator relative to the one proposed by Carroll et al. [1995. Measurement Error in Nonlinear Models. Chapman & Hall, New York] is evaluated numerically for the motivating example. User-friendly and fully documented Splus and SAS routines implementing these methods are available (http://www.hsph.harvard.edu/faculty/spiegelman/multsurr.html).
