Be unto me as a precious ointment : lady Grace Mildmay, sixteenth-century female practitioner
Lady Grace Mildmay's manuscripts represent an unusual presentation of three interrelated areas of family, devotion, and medicine. By examining her autobiography, meditations, and medical papers, I draw together literary analysis and discourses of female devotional and social practices with that of medical discourses to illustrate the ways in which women practitioners may have acquired and disseminated medical knowledge, and interacted with their patients, as well as how Lady Mildmay, and presumably other landed women practitioners, formed a textual community of women who administered medical treatment to lay people in late sixteenth-century England
«Be unto me as a precious ointment.: Lady Grace Mildmay, Sixteenth-Century Female Practitioner
Lady Grace Mildmay's manuscripts represent an unusual presentation of three
interrelated areas of family, devotion, and medicine. By examining her autobiography,
meditations, and medical papers, 1 draw together literary analysis and discourses of
female devotional and social practices with that of medical discourses to illustrate the
ways in which women practitioners may have acquired and disseminated medical knowledge,
and interacted with their patients, as well as how Lady Mildmay, and presumably other
landed women practitioners, formed a textual community of women who administered
medical treatment to lay people in late sixteenth-century England
Community Engagement in Journalism: Transferable Techniques for Mid-Sized Cities
57 pagesJournalists are becoming increasingly aware that they need to build relationships with the communities they serve. This paper explores the current discourses around community engagement, addresses challenges to this topic, argues for the importance of these practices and proposes techniques for carrying out community engagement within the context of Eugene as a representation of mid-sized cities. The proposed techniques emerged from interviews with six working journalists from Eugene, Ore., Los Angeles, Calif., Salt Lake City, Utah, and Boise, Idaho. This paper finds that engagement techniques can be promoted to create a formal infrastructure at an outlet or can be utilized by journalists individually
Research on nonlinear optical materials: an assessment. IV. Photorefractive and liquid crystal materials
This panel considered two separate subject areas: photorefractive materials used for nonlinear optics and liquid crystal materials used in light valves. Two related subjects were not considered due to lack of expertise on the panel: photorefractive materials used in light valves and liquid crystal materials used in nonlinear optics. Although the inclusion of a discussion of light valves by a panel on nonlinear optical materials at first seems odd, it is logical because light valves and photorefractive materials perform common functions
Time resolved observation of resonant and non-resonant contributions to the nonlinear susceptibility χ(3)
The resonant and nonresonant part of χ(3) are distinguished by their different time behavior. The medium is coherently excited by two picosecond light pulses of defined frequency difference and the state of the system is monitored by a third properly delayed probe pulse. Results are presented on neat liquids of carbontetrachloride and cyclohexane and on the mixture of CCl4: C6H12
Mobility of slow electrons in a polar crystal
We have obtained an approximate expression for the impedance function at all frequencies, temperatures, and coupling strengths of an electron coupled to a polar lattice (a system commonly called a polaron). The starting point for the calculation is the quantum mechanical expression for the expected current. The phonon coordinates are eliminated from this expression by well-known field-theory techniques. The resulting exact "influence functional" is then approximated by a corresponding quadratic "influence functional" which, it is hoped, imitates the real polaron. Correction terms are computed to account for the difference between the approximate impedance and the exact polaron impedance in a manner closely analogous to Feynman's treatment of the polaron self-energy. In fact, the analytic evaluation of the expression for the impedance obtained here is carried out using the approximate "influence functional" that was successfully employed in minimizing the binding (and free) energy of the polaron in earlier calculations. However, the accuracy obtained using this approximation, for the impedance calculation, is less satisfactory and its limitations are discussed. Nevertheless, beginning at intermediate coupling strengths, the approximate impedance produces a level structure of increasing complexity and narrowing resonances as the coupling strengthens. This suggests that further refinements may be fruitful. Methods for finding a better quadratic influence functional for use in our impedance expression as well as ways of improving the expression further are suggested. A comparison of our results with those of the Boltzmann equation points up interesting differences which arise from reversing the order of taking limits of zero frequency and coupling
Phase-conjugation of the isolated optical vortex using a flat surfaces
The robust method for obtaining the helical interference pattern due to the
phase-conjugation of an isolated optical vortex by means of the non-holographic
technique is proposed. It is shown that a perfect wavefront-reversal of the
vortex in a linear polarization state via even number of reflections is
achievable due to the turn of the photon's momentum with respect to the photon's orbital angular momentum projection . The
possible experimental realization is based upon like
reflections inside the confocal optical cavity. The alternative scheme
contains the Dove prism embedded in the optical with the odd number of
reflections from mirrors. This interferometric technique is
applicable to the optical tweezers, atomic traps, Sagnac laser loops and
metamaterials fabrication.Comment: 4 pages, 3 figures, submitted to referred journa
On the Localization of One-Photon States
Single photon states with arbitrarily fast asymptotic power-law fall-off of
energy density and photodetection rate are explicitly constructed. This goes
beyond the recently discovered tenth power-law of the Hellwarth-Nouchi photon
which itself superseded the long-standing seventh power-law of the Amrein
photon.Comment: 7 pages, tex, no figure
