Finding Common Feminist Ground: The Role of the Next Generation in Shaping Feminist Legal Theory

This article explores the ways in which current feminist frameworks are dividing the women’s movement along generational lines, thereby inhibiting progress in the struggle for gender equality. Third-wave feminists, or the generation of feminists that came of age in the 1990s and continues today, have been criticized for focusing on personal stories of oppression and failing to influence feminist legal theory. Yet this critique presupposes that third-wave feminism is fundamentally different from the feminism of past generations. In contrast, this article argues that third-wave feminism is rooted in the feminist legal theory developed in the prior generation. This article demonstrates that the third-wave appears to be failing to influence feminist legal theory not because it is theoretically different, but because third-wave feminists approach activism in such a different way. For example, third-wavers envision “women’s issues” broadly, and rely on new tactics such as online organizing. Using the case study of Spark, a nonprofit organization employing third-wave activism to support global grassroots women’s organizations, this article provides a model of this new brand of feminism in practice. This article proposes the adoption of social justice feminism, which advocates casting a broader feminist net to capture those who have been traditionally neglected by the women’s movement, such as low-income women and women of color. Social justice feminism is a way to broaden the focus from a rights-based approach to an examination of the dynamics of power and privilege that continue to shape women’s lives even when legal rights to equality have been won. Adopting social justice feminism can be a way to bridge second- and third-wave feminism and create a more robust and unified feminist movement, thereby mending the divisions that currently prevent unification in the women’s movement

Mixed collective states of many spins

Mixed states of samples of spin s particles which are symmetric under permutations of the particles are described in terms of their total collective spin quantum numbers. We use this description to analyze the influence on spin squeezing due to imperfect initial state preparation.Comment: Section V on extension of the results to atoms with more than two levels has been rewritten.

Many-Body Expanded Full Configuration Interaction. II. Strongly Correlated Regime

In this second part of our series on the recently proposed many-body expanded full configuration interaction (MBE-FCI) method, we introduce the concept of multideterminantal expansion references. Through theoretical arguments and numerical validations, the use of this class of starting points is shown to result in a focussed compression of the MBE decomposition of the FCI energy, thus allowing chemical problems dominated by strong correlation to be addressed by the method. The general applicability and performance enhancements of MBE-FCI are verified for standard stress tests such as the bond dissociations in H$_2$O, N$_2$, C$_2$, and a linear H$_{10}$ chain. Furthermore, the benefits of employing a multideterminantal expansion reference in accelerating calculations of high accuracy are discussed, with an emphasis on calculations in extended basis sets. As an illustration of this latter quality of the MBE-FCI method, results for H$_2$O and C$_2$ in basis sets ranging from double- to pentuple-$\zeta$ quality are presented, demonstrating near-ideal parallel scaling on up to almost $25000$ processing units.Comment: 41 pages, 4 tables, 10 figures, 1 SI attached as an ancillary fil

Many-Body Expanded Full Configuration Interaction. I. Weakly Correlated Regime

Over the course of the past few decades, the field of computational chemistry has managed to manifest itself as a key complement to more traditional lab-oriented chemistry. This is particularly true in the wake of the recent renaissance of full configuration interaction (FCI)-level methodologies, albeit only if these can prove themselves sufficiently robust and versatile to be routinely applied to a variety of chemical problems of interest. In the present series of works, performance and feature enhancements of one such avenue towards FCI-level results for medium to large one-electron basis sets, the recently introduced many-body expanded full configuration interaction (MBE-FCI) formalism [J. Phys. Chem. Lett., 8, 4633 (2017)], will be presented. Specifically, in this opening part of the series, the capabilities of the MBE-FCI method in producing near-exact ground state energies for weakly correlated molecules of any spin multiplicity will be demonstrated.Comment: 38 pages, 7 tables, 3 figures, 1 SI attached as an ancillary fil

In-Medium Properties of Vector Mesons in a Transport Approach

We present dilepton spectra from p+p and p+Nb collisions at a kinetic beam energy of 3.5 GeV, which were simulated with the GiBUU transport model assuming different in-medium scenarios. We compare these spectra to preliminary HADES data and show that GiBUU can describe the data reasonably well. Our simulations indicate that the intermediate dilepton-mass region is sensitive to the N-Delta electromagnetic transition form factor, which up to now is unmeasured in the time-like region.Comment: 12 pages, 4 figures, Proceedings of the XLIX International Winter Meeting on Nuclear Physics, 2011, Bormio, Ital

Study to develop improved methods to detect leakage in fluid systems, phase 3

Research was undertaken to design and fabricate a prototype flight weight ultrasonic contact sensor leak detection system and to perform the necessary testing to collect enough data to establish design parameters and develop necessary baseline operating characteristics. The prototype system consists of five channels and is capable for monitoring frequencies from 1 KHz to 110 KHz

In-medium Spectral Functions in a Coarse-Graining Approach

We use a coarse-graining approach to extract local thermodynamic properties from simulations with a microscopic transport model by averaging over a large ensemble of events. Setting up a grid of small space-time cells and going into each cell's rest frame allows to determine baryon and energy density. With help of an equation of state we get the corresponding temperature $T$ and baryon-chemical potential $\mu_{\mathrm{B}}$. These results are used for the calculation of the thermal dilepton yield. We apply and compare two different spectral functions for the $\rho$ meson, firstly a calculation from hadronic many-body theory and secondly a calculation from experimental scattering amplitudes. The results obtained with our approach are compared to measurements of the NA60 Collaboration. A relatively good description of the data is achieved with both spectral functions. However, the hadronic many-body calculation is found to be closer to the experimental data with regard to the in-medium broadening of the spectral shape.Comment: 5 pages, 1 figure; Contribution for FAIRNESS 2014 proceeding
