Gendered Due Process of Juvenile Justice

This Essay illustrates how the United States Constitution has developed gendered jurisprudence for children and families that affords children a higher level of due process in juvenile courts than is afforded to their parents. Appell discusses this jurisprudence through the lens of child protection and delinquency cases, followed by the laws treatment of children outside of the familial context. Appell highlights the higher level of constitutional freedom afforded children who break the law versus their parents who raise them and ends with a discussion of the implications this has on juvenile jurisprudence

Introduction to the Symposium: Access to Justice: Mass Incarceration and Masculinity Through a Black Feminist Lens

This Introduction to the Symposium, Race to Justice: Mass Incarceration and Masculinity through a Black Feminist Lens, rehearses the animating forces that led to a colloquium and a series of papers that explore the question of mass incarceration and the negative state engagement surrounding it through gendered and feminist lenses. The Introduction explains how an analysis of mass incarceration through the lens of gender complicates what is often conceived as a story about race. Instead mass incarceration can be more deeply understood through its gendered effects on men and the women and children connected to those men. These connections include the social and economic conditions of the community, new forms of sexuality experienced in prison, and resulting changes in identity. Building on the work of Angela Davis and Beth Ritchie, this symposium and its papers provide new insights and frameworks for mass incarceration. Symposium authors include Angela Harris, Frank Rudy Cooper, SpearIt, Kimberly Bailey, Jessica Dixon Weaver

On the Equivalence Between Type I Liouville Dynamical Systems in the Plane and the Sphere

Producción CientíficaSeparable Hamiltonian systems either in sphero-conical coordinates on an S2 sphere or in elliptic coordinates on a R2 plane are described in a unified way. A back and forth route connecting these Liouville Type I separable systems is unveiled. It is shown how the gnomonic projection and its inverse map allow us to pass from a Liouville Type I separable system with a spherical configuration space to its Liouville Type I partners where the configuration space is a plane and back. Several selected spherical separable systems and their planar cousins are discussed in a classical context

Lagrangian Formalism in Perturbed Nonlinear Klein-Gordon Equations

We develop an alternative approach to study the effect of the generic perturbation (in addition to explicitly considering the loss term) in the nonlinear Klein-Gordon equations. By a change of the variables that cancel the dissipation term we are able to write the Lagrangian density and then, calculate the Lagrangian as a function of collective variables. We use the Lagrangian formalism together with the Rice {\it Ansatz} to derive the equations of motion of the collective coordinates (CCs) for the perturbed sine-Gordon (sG) and $\phi^{4}$ systems. For the $N$ collective coordinates, regardless of the {\it Ansatz} used, we show that, for the nonlinear Klein-Gordon equations, this approach is equivalent to the {\it Generalized Traveling Wave Ansatz} ({\it GTWA})Comment: 9 page

Geodesics around Weyl-Bach's Ring Solution

We explore some of the gravitational features of a uniform ring both in the Newtonian potential theory and in General Relativity. We use a spacetime associated to a Weyl static solution of the vacuum Einstein's equations with ring like singularity. The Newtonian motion for a test particle in the gravitational field of the ring is studied and compared with the corresponding geodesic motion in the given spacetime. We have found a relativistic peculiar attraction: free falling particle geodesics are lead to the inner rim but never hit the ring.Comment: 8 figures, 14 pages. LaTeX w/ subfigure, graphic
