    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

    Full text link
    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 H2_2O, N2_2, C2_2, and a linear H10_{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 H2_2O and C2_2 in basis sets ranging from double- to pentuple-ζ\zeta quality are presented, demonstrating near-ideal parallel scaling on up to almost 2500025000 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

    Full text link
    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

    Hubungan Persepsi Siswa Terhadap Punishment Yang Diberikan Guru Dan Kecerdasan Emosi Dengan Kedisiplinan

    Full text link
    This study aimed to determine the relationship of students' perceptions of punishment given to teachers and emotional intelligence with discipline. The subjects of this study were junior high school students of Kristen Petra 3 Surabaya eight grade, totaling 127 students. Data collection tools used in this study was scale of students' perception of punishment provided by the teacher, scale of emotional intelligence, and scale of discipline. Based on anareg, obtained anareg correlation coefficient F = 1.085, p = 0.341 (p > 0.05). This means that together there is no relationship between students' perceptions of punishment given to teachers and emotional intelligence discipline. Independent variable partial test students' perception of the teacher's punishment resulted in p = 0.155 (p > 0.05), this shows the independent variable students' perceptions of teachers' punishment given nothing to do with discipline. Partial test of emotional intelligence independent variable produces a p-value = 0.584 (at p > 0.05), the independent variables of emotional intelligence showed no relationship with the discipline

    Individual Security and Network Design with Malicious Nodes

    Full text link
    Networks are beneficial to those being connected but can also be used as carriers of contagious hostile attacks. These attacks are often facilitated by exploiting corrupt network users. To protect against the attacks, users can resort to costly defense. The decentralized nature of such protection is known to be inefficient but the inefficiencies can be mitigated by a careful network design. Is network design still effective when not all users can be trusted? We propose a model of network design and defense with byzantine nodes to address this question. We study the optimal defended networks in the case of centralized defense and, for the case of decentralized defense, we show that the inefficiencies due to decentralization can be fully mitigated, despite the presence of the byzantine nodes.Comment: 19 pages, 3 figure

    Investigating in-medium properties of the ω\omega meson via the ω→π0γ\omega\rightarrow\pi^0\gamma decay

    We investigate the feasibility of studying in-medium properties of the ω\omega meson in photoproduction experiments via the decay ω→π0γ\omega\rightarrow\pi^0\gamma. We use the GiBUU transport model to compare different methods of obtaining in-medium information, such as the invariant mass spectrum, transparency ratio, excitation function and momentum spectrum. We show that the final-state interaction of the pion poses a major obstacle for the interpretation of the invariant mass spectrum. The other three observables turn out to be fairly independent of final-state interactions and thus can give access to the ω\omega's in-medium properties.Comment: 8 pages, 6 figure
