    Every Parent’s Worst Nightmare: Myths of Child Abductions in US News

    Through a content analysis, this study seeks to uncover the predominant narrative themes centered on gender and class that shaped mainstream U.S. newspaper coverage of child kidnappings from 2000-2003. The abductions that dominated news coverage were neither random nor representative cases; clear patterns emerged in the kidnappings that garnered the most media attention. Though statistically rare, the news media disproportionally covered stories of young Caucasian girls being snatched from their middle-to-upper class homes by male strangers, manufacturing a nationwide epidemic. Our analysis reveals how gender and class were used to construct vulnerable girl victims and predatory male perpetrators. News narratives organized kidnapping stories using frames of family values, community cohesion and patriotism, while also disproportionally exaggerating the “stranger danger” myth. We argue these kidnapping narratives of vulnerable violated girls and predatory male “othered” strangers reflect a post-9/11 America struggling from the cultural aftershocks of national crisis and economic uncertainty

    Diversity in times of austerity: documenting resistance in the academy

    What happens to feminism in the university is parallel to what happens to feminism in other venues under economic restructuring: while the impoverished nation is forced to cut social services and thereby send women back to the hierarchy of the family, the academy likewise reduces its footprint in interdisciplinary structures and contains academic feminists back to the hierarchy of departments and disciplines. When the family and the department become powerful arbiters of cultural values, women and feminist academics by and large suffer: they either accept a diminished role or are pushed to compete in a system they recognize as antithetical to the foundational values of feminist priorities of social justice. Collaborative work to nurture diversity and interdisciplinarity does not register as individual accomplishment. This paper considers the necessity of this type of academic work to further the vision of a society committed to the collective values espoused by feminism and other areas in social justice

    Time-domain chirally-sensitive three-pulse coherent probes of vibrational excitons in proteins

    The third order optical response of bosonic excitons is calculated using the Green's function solution of the Nonlinear Exciton Equations (NEE) which establish a quasiparticle-scattering mechanism for optical nonlinearities. Both time ordered and non ordered forms of the response function which represent time and frequency domain techniques, respectively, are derived. New components of the response tensor are predicted for isotropic ensembles of periodic chiral structures to first order in the optical wavevector. The nonlocal nonlinear response function is calculated in momentum space, where the finite exciton-exciton interaction length greatly reduces the computational effort. Applications are made to coupled anharmonic vibrations in the amide I infrared band of peptides. Chirally-sensitive and non sensitive signals for alpha helices and antiparallel beta sheets are compared.Comment: 26 pages, 6 figure

    Application of time-dependent density functional theory to optical activity

    As part of a general study of the time-dependent local density approximation (TDLDA), we here report calculations of optical activity of chiral molecules. The theory automatically satisfies sum rules and the Kramers-Kronig relation between circular dichroism and optical rotatory power. We find that the theory describes the measured circular dichroism of the lowest states in methyloxirane with an accuracy of about a factor of two. In the chiral fullerene C_76 the TDLDA provides a consistent description of the optical absorption spectrum, the circular dichroism spectrum, and the optical rotatory power, except for an overall shift of the theoretical spectrum.Comment: 17 pages and 13 PostScript figure
