Diction and Social Strata in Charles Chesnutt\u27s The Wife of Youth
Since Charles Chesnutt was on both the color and caste lines, his linguistic precision reflects a variety of cultural aspects. In “The wife of his Youth,” one can explore the caste differences between Mr. Ryder and Liza Jane through Chesnutt‟s choice of diction. The opening of the story postpones the plot to introduce and characterize Mr. Ryder in the context of the Blue Veins Society. Once established as a Blue Vein, Mr. Ryder necessarily exhibits a more varied and more studied diction than Liza Jane. This disparity becomes a condemnation of the seeking after upward mobility at the cost of relationships and core values. Since both characters tell the same story, Chesnutt provides a close comparison of their dictions and presents not only Liza Jane‟s story as more truthful but uses her qualities to revalue the Blue Vein Society. Diction plays a central role in the portrayal of different social castes. Cynthia Lehman examines several of Chesnutt‟s stories to analyze the social and political dimensions. She explains, “On the subject of language, as has been stated before, Charles Chestnutt‟s [sic] vocabulary was reflective of an attitude of White Americans that he wished to have portrayed in the novel to exhibit social realism,” (1996, p. 282). This attitude becomes apparent in most of Chesnutt‟s stories through the differences between Uncle Julius and the narrator. Nevertheless, in the case of “The Wife of his Youth,” Chesnutt juxtaposes the dictions of two central characters, Mr. Ryder and Liza Jane. Most simply, diction or lexical choice pertains to word choice including vocabulary and syntax (Harmon, 2009, p. 161). Readers understand aspects of Ryder‟s character through his word choice. On the other hand, Liza Jane‟s diction remains relatively undeveloped due to social restrictions based on her skin tone and temporal restrictions based on her years spent in a dedicated search for her husband
TISSUES AND TRAUMA: PAIN NEUROSCIENCE EDUCATION FOR VETERANS WITH POST-TRAUMATIC STRESS AND LOW BACK PAIN
Low back pain (LBP) is the top reason for Soldiers to seek medical care and one of the top reasons to be medically discharged. Mental health problems and psychosocial stressors have been increasing in Soldiers and are also top causes for medical discharge. Dysregulated stress has contributed to many Soldiers and Veterans to develop chronic LBP as well as mental health disorders like post-traumatic stress disorder (PTSD). Research suggests that psychosocial characteristics, as opposed to physical factors or tissue health, contribute to chronic pain the most. Focusing entirely on tissues for individuals seeking care for LBP can increase disability and vulnerability. Attributing physical pain to mental health concerns, however, risks stigmatizing patients or making them feel dismissed. The purpose of this dissertation was to develop a pain neuroscience education (PNE) program for Veterans and Soldiers with LBP and stress and determine if PNE is more effective in improving disability, PTSD symptoms, and beliefs about pain compared to traditional education about back pain and stress.
This dissertation demonstrated that Veterans with PTSD can comprehend the neuroscience of pain and PTSD at a comparable level to a highly educated Veteran and medical panel without PTSD when adjusting for education. Since a proportion of participants were concerned that using military examples in PNE might increase PTSD symptoms, however, results from pilot testing suggested that the PNE materials developed for this dissertation should be tested in a clinical trial to ensure they do not increase PTSD symptoms.
A systematic review and meta-analysis demonstrated that Veterans with PTSD have higher depression and pain-catastrophizing beliefs for a large effect size compared to Veterans without PTSD. Furthermore, Veterans with PTSD have significantly lower pain self-efficacy with a large effect size. Compared to Veterans without PTSD, Veterans with PTSD have higher pain and disability. These results, however, were not confirmed in Veterans presenting to a Physical Therapy clinic. In fact, this dissertation revealed that many of the negative outcomes previously attributed to PTSD in the literature may be due to the correlation between PTSD symptoms and pain-catastrophizing beliefs rather than from trauma. Furthermore, Veterans with chronic LBP do not appear to have different sensitivity levels to pressure based on PTSD symptoms.
Finally, the results from a randomized controlled trial provide evidence that PNE greatly improves the confidence of Veterans and Soldiers to increase participation in social, work, and life roles despite the pain as measured by the pain self-efficacy questionnaire. Participants in the experimental group were more likely to achieve a meaningful reduction in disability at the 8-week follow-up compared to the control group. Furthermore, Veterans and Soldiers with LBP were more satisfied with how PNE explains pain and believed the PNE curriculum connected with their military experiences better than traditional psychosocial education about stress. Participants in the experimental arm were less likely to believe that exercise is harmful compared to traditional education. Finally, PNE improved PTSD symptoms beyond the clinically meaningful threshold in the experimental arm. In conclusion, PNE appears to be an effective treatment for PTSD, disability, and pain-related beliefs in Veterans and Soldiers with chronic LBP. These results should be replicated in a larger sample to ensure generalizability beyond the current study
The Ministry of Passion and Meditation: Robert Southwell\u27s Marie Magdalens Funeral Teares and the Adaptation of Continental Influences
In his most popular prose work, Mary Magdalens Funeral Teares (1591), English Jesuit Robert Southwell adapts the Mary Magdalene tradition by incorporating the meditative practices of St. Ignatius Loyola coupled with the Petrarchan language of poetry. Thus, he creates a prose work that ministered to Catholic souls, appealed to Protestant audiences, and initiated the literature of tears in England. Southwell readapts the traditional image of Mary Magdalene for a Catholic Early Modern audience by utilizing the techniques of Jesuit meditation, which later flourished in the weeper texts of Richard Crashaw and George Herbert. His vividly imagined scenes also employ the Petrarchan and Ovidian language of longing and absence and coincide with both traditional and mystic early church writers such as Bernard and Augustine. Through this combination, Southwell’s Marie Magdalens Funeral Teares resonated with Catholics deprived of both ministry and the presence of Christ in the Eucharist. These contributions solidify Southwell’s place as a pivotal figure in the religious and literary contexts of Early Modern England
Explicit examples of resonances for Anosov maps of the torus
In [23], Slipantschuk, Bandtlow and Just gave concrete examples of Anosov
diffeomorphisms of the two-torus for which their resonances could be completely
described. Their approach was based on composition operators acting on analytic
anisotropic Hilbert spaces, and in this note we present a construction of
alternative anisotropic Hilbert spaces which helps to simplify parts of their
analysis and gives scope for constructing further examples.Comment: 23 pages, 4 figure
Composite modelling of subaerial landslide-tsunamis in different water body geometries and novel insight into slide and wave kinematics
This article addresses subaerial landslide-tsunamis with a composite (experimental-numerical) modelling approach. A shortcoming of generic empirical equations used for hazard assessment is that they are commonly based on the two idealised water body geometries of a wave channel (2D) or a wave basin (3D). A recent systematic comparison of 2D and 3D physical block model tests revealed wave amplitude differences of up to a factor of 17. The present article investigates two of these recently presented 2D-3D test pairs in detail, involving a solitary-like wave (scenario 1) and Stokes-like waves (scenario 2). Results discussed include slide and water particle kinematics and novel pressure measurements on the slide front. Instantaneous slide-water interaction power graphs are derived and potential and kinetic wave energies are analysed. Solitary wave theory is found most appropriate to describe the wave kinematics associated with scenario 1, whereas Stokes theory accurately describes the tsunami in scenario 2. The data of both scenarios are further used to calibrate the smoothed particle hydrodynamics (SPH) code DualSPHysics v3.1, which includes a discrete element method (DEM)-based model to simulate the slide-ramp interaction. Five intermediate geometries, lying between the ideal 2D and 3D cases, are then investigated purely numerically. For a “channel” geometry with a diverging side wall angle of 7.5°, the wave amplitudes along the slide axes were found to lie approximately halfway between the values observed in 2D and 3D. At 45°, the amplitudes are practically identical to those in 3D. The study finally discusses the implications of the findings for engineering applications and illustrates the potential and current limitations of DualSPHysics for landslide-tsunami hazard assessment
Geographic and ecologic distributions of the Anopheles gambiae complex predicted using a genetic algorithm
This is the publisher's version, also available electronically from http://www.ajtmh.org/content/70/2/105.The distribution of the Anopheles gambiae complex of malaria vectors in Africa is uncertain due to under-sampling of vast regions. We use ecologic niche modeling to predict the potential distribution of three members of the complex (A. gambiae, A. arabiensis, and A. quadriannulatus) and demonstrate the statistical significance of the models. Predictions correspond well to previous estimates, but provide detail regarding spatial discontinuities in the distribution of A. gambiae s.s. that are consistent with population genetic studies. Our predictions also identify large areas of Africa where the presence of A. arabiensis is predicted, but few specimens have been obtained, suggesting under-sampling of the species. Finally, we project models developed from African distribution data for the late 1900s into the past and to South America to determine retrospectively whether the deadly 1929 introduction of A. gambiae sensu lato into Brazil was more likely that of A. gambiae sensu stricto or A. arabiensis
Improved Fan Control
Cooling large computer enclosures is an increasingly difficult task, usually requiring multiple fans and/or multiple rotors per fan. A technique is disclosed that reduces stress on a power distribution system for multiple fans by delaying individual fan control signals at the final distribution point near the fans

Bench-to-bedside review: Inhaled nitric oxide therapy in adults
Nitric oxide (NO) is an endogenous mediator of vascular tone and host defence. Inhaled nitric oxide (iNO) results in preferential pulmonary vasodilatation and lowers pulmonary vascular resistance. The route of administration delivers NO selectively to ventilated lung units so that its effect augments that of hypoxic pulmonary vasoconstriction and improves oxygenation. This 'Bench-to-bedside' review focuses on the mechanisms of action of iNO and its clinical applications, with emphasis on acute lung injury and the acute respiratory distress syndrome. Developments in our understanding of the cellular and molecular actions of NO may help to explain the hitherto disappointing results of randomised controlled trials of iNO
