Gender stereotypes: sexuality and contraception in Mexican university students of middle class

Since feminist studies and gender perspective, sexuality and reproduction continue to be a topic of interest in Mexico. The objective of this study was to identify gender stereotypes in sexuality and contraception practices in Mexican university students of middle class. We used a qualitative methodology with in-depth interviews, using as analysis axes the sexual and contraception practices. The results showed gender stereotypes in university students as active, seductive and conquerors, characterized by a double standard of morality in the type of relationship: Formal where love, affection, trust and commitment are present, and Informal, where a love relationship or sexual exclusivity is not incorporated.

The Deleuze Spray, New York 1977 : an Interview with Sanford Kwinter, Professor of Architectural Theory and Criticism at the Harvard Graduate School of Design, on the Architectural Reception of Gilles Deleuze in America

So what do you want to know? I was in Paris between ‘75 and ‘78. But about half way through, Sylvère published the Anti-Oedipus issue of Semiotext(e) and, actually, that was for me one of the deciding events that made me decide to come to the United States, to come study at Columbia University. There appeared to be this little group working at Columbia working around these issues. In 1970, in Paris even, Deleuze was a cult – there was an incredibly small number of people following Deleuze... A transcript of my Interview with Kwinter about the Architectural Reception of Deleuze in America, which took place at Jerry’s,' Soho, New York, 15 January 2003. The transcript appeared as an Appendix at the back of my Masters Thesis undertaken at Yale School of Architecture, printed May 2003.

Tracking control of a class of Hamiltonian mechanical systems with disturbances

This paper presents a trajectory-tracking control strategy for a class of mechanical systems in Hamiltonian form. The class is characterised by a simplectic interconnection arising from the use of generalised coordinates and full actuation. The tracking error dynamic is modelled as a port-Hamiltonian Systems (PHS). The control action is designed to take the error dynamics into a desired closed-loop PHS characterised by a constant mass matrix and a potential energy with a minimum at the origin. A transformation of the momentum and a feedback control is exploited to obtain a constant generalised mass matrix in closed loop. The stability of the close-loop system is shown using the close-loop Hamiltonian as a Lyapunov function. The paper also considers the addition of integral action to design a robust controller that ensures tracking in spite of disturbances. As a case study, the proposed control design methodology is applied to a fully actuated robotic manipulator.

Resolution of Singularities for a Class of Hilbert Modules

Let M be the completion of the polynomial ring C(z) under bar] with respect to some inner product, and for any ideal I subset of C (z) under bar], let I] be the closure of I in M. For a homogeneous ideal I, the joint kernel of the submodule I] subset of M is shown, after imposing some mild conditions on M, to be the linear span of the set of vectors {p(i)(partial derivative/partial derivative(w) over bar (1),...,partial derivative/partial derivative(w) over bar (m)) K-I] (., w)vertical bar(w=0), 1 <= i <= t}, where K-I] is the reproducing kernel for the submodule 2] and p(1),..., p(t) is some minimal ``canonical set of generators'' for the ideal I. The proof includes an algorithm for constructing this canonical set of generators, which is determined uniquely modulo linear relations, for homogeneous ideals. A short proof of the ``Rigidity Theorem'' using the sheaf model for Hilbert modules over polynomial rings is given. We describe, via the monoidal transformation, the construction of a Hermitian holomorphic line bundle for a large class of Hilbert modules of the form I]. We show that the curvature, or even its restriction to the exceptional set, of this line bundle is an invariant for the unitary equivalence class of I]. Several examples are given to illustrate the explicit computation of these invariants.
