Minding the body, sexing the brain: hormonal truth and the post-feminist hermeneutics of adolescence

Drawing on feminist and queer epistemologies, this article is concerned with the post-feminist media’s construction of girls’ sexual subjecthood. Broadly defined as a biopolitical ideal, post-feminism is here related to a set of principles of the neoliberal art of government. It will be argued that these principles ethically sustain the exponential mainstreaming of a post-feminist hermeneutics of adolescence and its programme of governmentality. The article also links post-feminism to a particular methodology of subjectification, ultimately locating its hermeneutics of adolescence within the pornographic and pharmacological imperatives of contemporary capitalism. On the empirical level, the analysis explores how techno-scientific discourses and bodily figurations (namely brains and hormones) enter the discursive apparatus of a Portuguese girls’ magazine, giving ideological ground to a distinctive production of adolescent body-subjects. Post-feminist media markets are finally discussed as a significant segment of the capitalist industrialisation of sexual difference that frames the general problematic of this study.

Debates feministas sobre pornografia heteronormativa: estéticas e ideologias da sexualização

This paper revisits the feminist debate on heteronormative pornography and analyzes its production of polarized discourses, particularly those that have explored psychological sciences to legitimize their positions. Locating the porn industry within the mechanics of contemporary capitalism, we propose to rethink the meanings of pornography beyond the strict boundaries of the traditional social psychology and the conservative North American feminism. The paramount role played by pornography in the sex industries is nowadays inseparable from the technological proliferation of the media and the increasing sexualization of its markets. In this article - an analysis of texts and discourses - we situate pornography in a broader and more reflexive phenomenology, crossing a constructionist-feminist approach with critical social psychology.

THE STRUCTURE AND PHOTOLUMINESCENCE OF ERBIUM DOPED NANOCRYSTALLINE SILICON THIN FILMS PRODUCED BY REACTIVE MAGNETRON SPUTTERING

We have produced and studied undoped and erbium-doped nanocrystalline silicon thin films in order to evaluate the erbium influence on the film microstructure and how this correlates with the photoluminescence properties. Films were grown by reactive RF sputtering. For the doped films metallic erbium was added to the c-Si target. The structural parameters and the chemical composition of the different samples were investigated by X-ray in the grazing incidence geometry, Raman spectroscopy, ellipsometry and Rutherford Back Scattering. The effect of the nc-Si/SiOx matrix ,i.e., nc-Si volume fraction and the presence of SiO and/or SiO2 phases, on the erbium photoluminescence efficiency is discussed.
