A Companion to Gower
No full textRobert Epstein is a contributing author, “London, Southwark, Westminster: Gower’s Urban Contexts”.
Book description:
Chaucer, Gower and Lydgate were the three poets of their time considered to have founded the English poetic tradition. Gower, like Lydgate, eventually fell victim to changing tastes but is now enjoying renewed scholarly attention. Current work in manuscript studies, linguistic studies, vernacularity, translation, politics, and the contexts of literary production has found a rich source in Gower\u27s trilingual, learned, and politically engaged corpus. This Companion to Gower offers essays by scholars from Britain and North America, covering Gower\u27s works in all three of his languages; they consider his relationships to his literary sources, and to his social, material and historical contexts; and they offer an overview of the manuscript, linguistic, and editorial traditions. Five essays concentrate specifically on the Confessio Amantis, Gower\u27s major Middle English work, reading it in terms of its relationship to vernacular and classical models, its poetic style, and its treatment of such themes as politics, kingship, gender, sexuality, authority, authorship and self-governance. A reference bibliography, arranged as a chronology of criticism, concludes the volume.https://digitalcommons.fairfield.edu/english-books/1075/thumbnail.jp
The “strophe d’Hélinand” and John Gower
No full textCet essai montre que le poète anglais de la fin du xive siècle John Gower, auteur du Mirour de l’Omme, le dernier et le plus long exemple connu de poème en strophes d’Hélinand, connaissait en entier Les Vers de la Mort, probablement par un manuscrit issu d’un monastère cistercien. Ainsi il est possible d’envisager non seulement comment Gower a fait sienne l’efficacité moralisatrice de la strophe d’Hélinand, mais aussi les modifications rhétoriques qu’il y a apportées, en l’adaptant à ses besoins particuliers.This essay argues that the late 14th-century English poet John Gower, author of the Mirour de l’Omme, the latest and longest known example of a poem using the strophe d’Hélinand, knew the Vers de la Mort in full, probably in a manuscript from a Cistercian monastery. Thus it is possible to consider not only how Gower absorbed the moralizing effectiveness of strophe d’Hélinand but also the rhetorical modifications he made to it, in re-conforming it to his own particular uses

Global dynamics in the leslie-gower model with the allee effect
No full textWe complete the global bifurcation analysis of the Leslie-Gower system with the Allee effect which models the dynamics of the populations of predators and their prey in a given ecological or biomedical system. In particular, studying global bifurcations of limit cycles, we prove that such a system can have at most two limit cycles surrounding one singular point.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Numerical Analysi
Herschel Gower Papers Finding Aid
No full textFinding aid for a collection. Collection description: The Herschel Gower Papers primarily comprises 6.05 linear feet of manuscript materials, which include drafts of an unpublished novel with its title and text changes in various versions. The papers also include manuscripts of his novel Faces in a Nashville Arcade and of his biography of Charles Dahlgren, Charles Dahlgren of Natchez: The Civil War and Dynastic Decline.
Professor Gower was a friend of writer Mildred Haun and her literary executor. His work as an editor of her stories is represented in these papers.
In addition there are articles and research notes and materials concerning Randal McGavock and his descendants, the Howell family and their descendants, and articles and books he wrote on the historic community of Beersheba Springs, Tennessee. There are subject files for his research on folklore, and for the D. Shelby Williams Trial which he used as background for his unpublished novel, and materials relating to poet John Crowe Ransom and author Peter Taylor.
These papers include a collection of correspondence and newspaper articles on the Yeatman and Polk families and their family ties with Gustave Eiffel, builder of the Eiffel Tower. There are fourteen reel to reel and cassette tape recordings, many of them songs recorded by the Scottish singer Jeannie Robertson.http://www.library.vanderbilt.edu/speccol/mss/gowerh/gower-herschel.shtm
The author portraits in the Bedford Psalter-Hours: Gower, Chaucer and Hoccleve
No full textAN inscribed portrait of John Gower, literary champion of Lancastrian kingship, provides the key to the reading of the unique illustrative programme of the Duke of Bedford's Psalter-Hours, Add. MS. 42131, the only manuscript he is known to have commissioned in England. Two hundred and ninety of the 300 minor text divisions are illustrated with portrait heads; a national portrait gallery of Lancastrian friends and foes is concealed in the initials of carefully selected texts. Many of the portraits are repeated, creating distinct subtexts; Gower himself appears ten times as prophet, preacher, and penitent lending the weight of his moral authority to the imagery. The depiction of contemporaries within the text of the Psalter is almost without precedent in the Middle Ages; the exception is in a Bible which was probably made for the Duke's father, Henry IV, by the artist of the inscribed portrait of Gower. This invasion of scriptural text defies convention and, it might be argued, good taste
Events Detection of Anticipatory Postural Adjustments through a Wearable Accelerometer Sensor Is Comparable to That Measured by the Force Platform in Subjects with Parkinson’s Disease
No full textOut-of-the-lab instrumented gait testing focuses on steady-state gait and usually does not include gait initiation (GI) measures. GI involves Anticipatory Postural Adjustments (APAs), which propel the center of mass (COM) forward and laterally before the first step. These movements are impaired in persons with Parkinson’s disease (PD), contributing to their pathological gait. The use of a simple GI testing system, outside the lab, would allow improving gait rehabilitation of PD patients. Here, we evaluated the metrological quality of using a single inertial measurement unit for APA detection as compared with the use of a gold-standard system, i.e., the force platforms. Twenty-five PD and eight elderly subjects (ELD) were asked to initiate gait in response to auditory stimuli while wearing an IMU on the trunk. Temporal parameters (APA-Onset, Time-to-Toe-Off, Time-to-Heel-Strike, APA-Duration, Swing-Duration) extracted from the accelerometric data and force platforms were significantly correlated (mean(SD), r: 0.99(0.01), slope: 0.97(0.02)) showing a good level of agreement (LOA [s]: 0.04(0.01), CV [%]: 2.9(1.7)). PD showed longer APA-Duration compared to ELD ([s] 0.81(0.17) vs. 0.59(0.09) p < 0.01). APA parameters showed moderate correlation with the MDS-UPDRS Rigidity, Characterizing-FOG questionnaire and FAB-2 planning. The single IMU-based reconstruction algorithm was effective in measuring APAs timings in PD. The current work sets the stage for future developments of tele-rehabilitation and home-based exercises
Cost analysis of technological vs. conventional upper limb rehabilitation for patients with neurological disorders: an Italian real-world data case study
No full textIntroduction: Most patients suffering from neurological disorders endure varying degrees of upper limb dysfunction, limiting their everyday activities, with only a limited number regaining full arm use. Robotic and technological rehabilitation has been demonstrated to be a feasible solution to guarantee an effective rehabilitation to recover upper limb performance or to prevent complications of upper limb immobility. However, there is currently a lack of studies which analyze the sustainability of robotic and technological rehabilitation by comparing its costs to conventional rehabilitation pathways.
Methods: Since technology-based and conventional rehabilitation of the upper limb have been demonstrated to have comparable efficacy when the rehabilitation dose is matched, our study concentrates on a cost minimization analysis. The aim of the study is to compare the costs of a “mixed” rehabilitation cycle, which combines conventional and technology-based treatments (the latter delivered with a single therapist supervising several patients), with a cycle of purely conventional treatments. This has been done by developing a cost model and retrospectively analyzing the costs sustained by an Italian hospital which has adopted such a mixed model. A sensitivity analysis has been done to identify the parameters of the model that have the greatest influence on cost difference and to evaluate their optimal values in terms of efficiency of mixed rehabilitation. Finally, probabilistic simulations have been applied to consider the variability of model parameters around such optimized values and evaluate the probability of achieving a given level of savings.
Results: We found a cost difference of 49.60 € per cycle in favor of mixed rehabilitation. The sensitivity analysis demonstrated that, in the situation of the hospital under investigation, the parameter having the largest influence on the cost difference is the number of robotic treatments in a mixed rehab cycle. Probabilistic simulations indicate a probability higher than 98% of an optimized mixed rehabilitation cycle being less expensive than a pure conventional one.
Conclusion: Through a retrospective cost analysis, we found that the technology-based mixed rehabilitation approach, within a specific organizational model allowing a single physiotherapist to supervise up to four patients concurrently, allowed cost savings compared to the conventional rehabilitation model
Cyclicity of the Limit Periodic Sets for a Singularly Perturbed Leslie-Gower Predator-Prey Model with Prey Harvesting
No full textIn this paper, we study the Leslie–Gower predator–prey model with Michaelis–Menten type
prey harvesting. Our main focus is on the cyclicity of diverse limit periodic sets, including a
generic contact point, canard slow–fast cycles, transitory canards, slow–fast cycles with two
canard mechanisms, singular slow–fast cycle, etc. We develop new techniques for finding the
maximum number of limit cycles produced by slow–fast cycles containing both the generic
and degenerate contact point away from the origin (such slow–fast cycles are the transitory
canards and cycles with two canard mechanisms). It can be applied not only to the Leslie–
Gower predator–prey model, but more general systems as well. The main tool is geometric
singular perturbation theory including cylindrical blow-up and the notion of slow divergence
integral. We also study dynamics near the origin using non-standard techniques (constructing
generalized normal sectors). The uniqueness and stability of a relaxation oscillation is shown
using the notion of entry–exit function. Some interesting dynamical phenomena, such as
relaxation oscillation and canard explosion, are simulated to illustrate the theoretical results.Acknowledgements
