Elisha: a problem in legend and history

Thesis (Ph. D.)--Boston UniversityStatement of the Problem. The dissertation is an investigation of the mixture of legend and history in the Elisha cycle in II Kings, attempting to discover to what extent the interests and life of the historic Elisha can be authenticated. The Elisha cycle is used as the basis for exploring the functions of legend and history in Biblical traditions. A secondary problem is an evaluation of the relationship between Elijah and Elisha, especially at those points where it is frequently asserted that Elisha traditions are adaptations of Elijah traditions. Procedure. The materials of the Elisha cycle are examined with respect to their present nature and possible origins through the use of form- and literary-critical methods. These traditions are grouped according to the roles which the early preservers of the Elisha materials appear to have assigned to the prophet. Three such roles are considered: 1) wonder worker; 2) cultic prophet; 3) political prophet. Elijah and Elisha traditions are compared at those points at which the prophets are associated either historically or through doublets in the traditions. Talmudic and patristic writings are examined to compare the emphases of Elisha's ministry in Kings with the aspects of Elisha's ministry which appealed to later Jewish and Christian writers. Conclusions. 1. The three roles considered prove to be the most adequate bases for comprehending the varying traditions of the Elisha cycle. 2. The role of wonder worker is derived from Elisha's role as cultic prophet. The assumption that Elisha can work wonders is based on an acceptance of him as cultic prophet and as a leader of the "sons of the prophets." J. The roles of Elisha within the tradition are best explained if it is assumed that these materials were preserved by prophetic circles, especially the "sons of the prophets." 4. The preservation of the Elisha tradition by the "sons of the prophets" resulted in an emphasis upon prophetic roles for Elisha which would cease to be characteristic of classical prophecy after Amos. 5. Elisha's stature as a prophet was not enhanced by his historic and literary relationship to Elijah. The frequently asserted superiority of Elijah as a prophet is shown to result from judgments based both on the greater excellence of the literary traditions of Elijah and on his greater importance for Judaism. An examination of Elijah's importance in Judaism shows clearly that it rests on factors other than the quality of his historic ministry. 6. In four instances of parallelism between Elijah and Elisha traditions only one instance Kings 17:17-24 parallel to II Kings 4:8-37) demonstrates clearly a transfer from Elijah to Elisha traditions. 7• The legendary aspects of those traditions which picture Elisha as political prophet are not to be discounted since Elisha's participation in the political life of the nation is conceivable for the period in question. It is shown that the settings for the political traditions in the Elisha cycle are all authentic for the general period, even though specific dates cannot be attached to all such traditions. 8. The legendary aspects of the Elisha traditions are shown to serve an historical purpose in communicating the interests and needs of those among whom these traditions were preserved. The legends are important in expanding our understanding of group prophecy in Israel in the ninth century B.C. although they do not carry us to the historic Elisha

Advances in electrical impedance tomography and bioimpedance including applications in COVID-19 diagnosis and treatment

This focus collection aims at presenting recent advances in electrical impedance tomography (EIT) including algorithms, hardware and clinical applications. As the opportunity to attend conferences has been considerably reduced due to the COVID-19 pandemic, this collection will provide a unique opportunity for the community to continue to report new studies and applications, and broaden the outlook into new clinical areas including COVID-19 patients and new technologies such as biosensors, machine learning and image analysis

Innovative librarians: Harnessing passion and involvement for library metamorphosis

During 2010 the RMIT University Library formed the 'Innovative Librarians Group' (ILG). The idea for the ILG was conceived from a debrief meeting with the University Librarian and acting Staff Development Librarian for the group's leader on her return from the Aurora leadership course. The ILG combined her interests in shifting the library staff mindset toward innovation and forward thinking, and integrating a technology focus into the library environment

Analysis and compensation for errors in electrical impedance tomography images and ventilation-­related measures due to serial data collection

Electrical impedance tomography (EIT) is increasingly being used as a bedside tool for monitoring regional lung ventilation. However, most clinical systems use serial data collection which, if uncorrected, results in image distortion, particularly at high breathing rates. The objective of this study was to determine the extent to which this affects derived parameters. Raw EIT data were acquired with the GOE­MF II EIT device (CareFusion, Höchberg, Germany) at a scan rate of 13 images/s during both spontaneous breathing and mechanical ventilation. Boundary data for periods of undisturbed tidal breathing were corrected for serial data collection errors using a Fourier based algorithm. Images were reconstructed for both the corrected and original data using the GREIT algorithm, and parameters describing the filling characteristics of the right and left lung derived on a breath by breath basis. Values from the original and corrected data were compared using paired t­ tests. Of the 33 data sets, 23 showed significant differences in filling index for at least one region, 11 had significant differences in calculated tidal impedance change and 12 had significantly different filling fractions (p = 0.05). We conclude that serial collection errors should be corrected before image reconstruction to avoid clinically misleading results

A direct D-bar reconstruction algorithm for recovering a complex conductivity in 2-D

A direct reconstruction algorithm for complex conductivities in $W^{2,\infty}(\Omega)$, where $\Omega$ is a bounded, simply connected Lipschitz domain in $\mathbb{R}^2$, is presented. The framework is based on the uniqueness proof by Francini [Inverse Problems 20 2000], but equations relating the Dirichlet-to-Neumann to the scattering transform and the exponentially growing solutions are not present in that work, and are derived here. The algorithm constitutes the first D-bar method for the reconstruction of conductivities and permittivities in two dimensions. Reconstructions of numerically simulated chest phantoms with discontinuities at the organ boundaries are included.Comment: This is an author-created, un-copyedited version of an article accepted for publication in [insert name of journal].

The transverse Zeeman effect of the green auroral line; An experimental proof of the existence of quadrupole radiation

The transverse Zeeman effect of the green auroral line was photographed. The pattern is of the type (1), 2/1, in complete agreement with the prediction made by Rubinowicz on the basis of the theory of quadrupole radiation

Effects of patient recumbency position on neonatal chest EIT

This paper investigates the overlooked effects of the patient recumbency positions on one of the key clinically used parameters in chest electrical impedance tomography (EIT) monitoring – the silent spaces. This parameter could impact medical decisions and interventions by indicating how well each lung is being ventilated. Yet it is largely dependent on assumptions of prior model at the reconstruction stage and the closely linked region of interest (ROI) during the final calculations. The potential effect of switching recumbency modes on silent spaces as a results of internal organ movements and consequently changes in initial assumptions, has been studied. The displacement and deformations caused by posture changes from supine to lateral recumbent were evaluated via simulations considering the simultaneous gravity-dependent movement and/or deformations of heart, mediastinum, lungs and the diaphragm. The reliability of simulations was verified against reference radiography images of an 18-month-old infant in supine and decubitus lateral positions. Inspecting a set of 10 patients from age range of 1 to 2 years old revealed improvements of up to 30% in the silent space parameters when applying posture consistent amendments as opposed to fixed model/ROI to each individual. To minimize the influence of image reconstruction technique on the results two different EIT reconstruction algorithms were implemented. The outcome emphasized the importance of including recumbency situation during chest EIT monitoring within the considered age range

Effect of the measurement on the decay rate of a quantum system

We investigated the electron tunneling out of a quantum dot in the presence of a continuous monitoring by a detector. It is shown that the Schr\"odinger equation for the whole system can be reduced to new Bloch-type rate equations describing the time-development of the detector and the measured system at once. Using these equations we find that the continuous measurement of the unstable system does not affect its exponential decay, $\exp (-\Gamma t)$, contrary to expectations based on the Quantum Zeno effect . However, the width of the energy distribution of the tunneling electron is no more $\Gamma$, but increases due to the decoherence, generated by the detector.Comment: Additional explanations are added.
