Comprehensive Bibliography of Chadic and Hausa Linguistics, Third Edition
No full textThe Comprehensive Bibliography of Chadic and Hausa Linguistics is an updated, expanded, and corrected edition of the print book published some twenty years ago by Rüdiger Köppe Verlag (Newman 1996). The outpouring of new publications on Chadic and Hausa in the ensuing years created the need for an updated bibliography. The first edition of this online bibliography was published in 2012 at Bayreuth University, the second edition in 2013 at Indiana University (http://hdl.handle.net/2022/16600), and the current third edition in 2015, also at Indiana University. This comprehensive bibliography covers all works written on Chadic and Hausa languages and linguistics dating from 1790 to the present. In addition to published books and articles, the bibliography includes unpublished Ph.D. dissertations and master's theses. The bibliography is international in scope and covers works regardless of the language in which they were written. For example, there are close to a hundred works written in Hausa. Titles of works in languages other than English, French, or German are accompanied by English translations. Russian titles in Cyrillic script are transliterated into Roman script. Book reviews are listed under the entry for the book being reviewed. A new feature of this 3rd edition is the addition of a Book Review Author Index, which indicates all the books that any individual has reviewed. Finally, the bibliography contains a section consisting of obituaries, (auto-) biographical essays, and related works on major scholars, now deceased, who have contributed significantly to Chadic or Hausa linguistics
Towards the tumble resistant microlight
No full textThe tumble mode is a pitching departure from controlled flight which leads to a pitch autorotation that is generally unrecoverable – resulting in vertical ground impact, usually preceded by in-flight breakup (the mechanism for which, surprisingly, can sometimes prevent loss of life). This was identified in work led by the British Microlight Aircraft Association beginning in 1997 as a response to a number of fatal accidents in Rogallo winged microlight aeroplanes, although the tumble is also known to occur to hang-gliders. This paper explains how this class of aeroplane is controlled, and how it has been found that they can enter the tumble mode. The mechanism by which the tumble can be entered is described. This has led to work showing how flight testing can be used to establish and demonstrate resistance to tumble entry – particularly important with increasing number of very high performance flexwings. These flight tests will be explained, together with the significance of the results. Recent accident investigation work has also shown a new mechanism of tumble entry, through partial failure of the A-frame structure and the pitch-trimmer mechanism. Also described is a possible relevance to well known historical accidents to flying wing aeroplanes– specifically the YB-49 and dH-108, and discovered data on the characteristics of the BKB-1flying wing glider; are also described
Grid-free models of multicellular systems, with an application to large-scale vortices accompanying primitive streak formation
No full textThis paper is comprised of two parts. In the first we provide a brief overview of grid-free methods for modeling multicellular systems. We focus on an approach based on Langevin equations, in which inertia is ignored, and stochastic effects on cell motion are included. The discussion starts with simpler models, in which cells are modeled as adhesive spheres. We then turn to more sophisticated approaches in which nontrivial cell shape is accommodated, including the recently introduced Subcellular Element Model, in which each cell is described as a cluster of adhesively coupled over-damped subeellular elements, representing patches of cytoskeleton. In the second part of the paper we illustrate the use of a standard grid-free cell-based model to computationally probe interesting new features associated with primitive streak formation in the chick embryo. Streak formation is a key developmental step in amniotes (i.e., birds, reptiles, and mammals), and can be observed in detail in the chick embryo, where the streak extends across a tightly-packed two-dimensional sheet (the epiblast) comprised of about 50,000 cells. The Weijer group [Cui, Yang, Chuai, Glazier, and Weijer, Dev. Biol. 284 (2005) 37-47] recently observed that streak formation is accompanied by coordinated cell movement lateral to the streak, resulting in two large counter-rotating vortices. We study a mechanism based on cell polarity (in the plane of the epiblast) that provides an explanation for these vortices, and test it successfully using computer simulations. This mechanism is robust, since the emergent vortex formation depends only on the gross features of the initial spatial distribution of planar polarity in the epiblast. (c) 2008, Elsevier Inc.</p
Interview with Marvin Newman
No full textProf. Marvin Newman grew up in Chicago, Illinois, and South Florida. He received his bachelor’s degree from Northwestern University in 1956, then continued his studies at the University’s law school, where he earned his L.L.B. and J.D. degrees, graduating magna cum laude.
With his wife and newborn daughter, Newman moved to Orlando in 1960 and began practicing as an attorney. He joined Rollins in 1961 as an adjunct lecturer in Business Law. His passion for the subject was evident, and within a year, he was teaching classes Monday through Thursday and sometimes on the weekends, while continuing to practice law and devote time to his growing family (the Newmans eventually had four daughters). In 1972 he became a tenured professor in the College of Arts and Sciences.
A popular and dedicated teacher, Prof. Newman received numerous awards over the course of his career, including the Hugh and Jeannette McKean Grant, The Outstanding Professor Award from the Crummer Graduate School of Business, The Rollins Decoration of Honor, and the College’s Distinguished Teaching Award. He introduced a total of 10 courses to the Rollins curriculum, but the one that is dearest to him is “Death and Dying.” This class was immediately popular with students and led to Prof. Newman becoming an internationally recognized scholar on ethical and legal issues related to the terminally ill. He is the author of numerous publications and co-author of several books on this topic, including To Die or Not to Die and Perspectives on Death and Dying.
Prof. Newman retired from Rollins in 2011. Looking back on his teaching career, he said, “I feel that it’s the memories my students will have of me that will count more than the assets that I leave. So it’s been wonderful.

Quantifying metastatic inefficiency:rare genotypes versus rare dynamics
No full textWe introduce and solve a 'null model' of stochastic metastatic colonization. The model is described by a single parameter ?: the ratio of the rate of cell division to the rate of cell death for a disseminated tumour cell in a given secondary tissue environment. We are primarily interested in the case in which colonizing cells are poorly adapted for proliferation in the local tissue environment, so that cell death is more likely than cell division, i.e. ? 1, we find that the probability of establishment is exponentially rare, as expected, and yet the mean time for such rare events is of the form ~log (N)/(1 - ?) while the standard deviation of colonization times is ~1/(1 - ?). Thus, counter to naive expectation, for ? 1), i.e. the statistics show a duality mapping (1 - ?) --> (? - 1). We conclude our analysis with a study of heterogeneity in the fitness of colonising cells, and describe a phase diagram delineating parameter regions in which metastatic colonization is dominated either by low or high fitness cells, showing that both are plausible given our current knowledge of physiological conditions in human cancer
Muriel Spark as auto-biographer in <i>Curriculum</i> <i>Vitae</i>
No full textExamining Muriel Spark's main aims as an auto-biographer in her work Curriculum Vitae brings important resources in the exploration of the genre of autobiographical writing. This with the theoretical engagement, allows consideration of the critical issues surrounding the roles of author and reader in the construction of the literary self. Spark demands the reader participate in the constructon of textual meaning; overturning the conventions of autobiography, satirising its claims to omniscience and highlighting the impossibility of an authentic voice with regard to the self
A Practical Iron-Based Newman-Kwart Rearrangement Under Oxidative Conditions
No full textHerein, we report that iron(II)/ammonium persulfate in aqueous acetonitrile mediates the Newman-Kwart rearrangement of O-aryl carbamothioates. Electron-rich substrates react rapidly under moderate heating to afford the rearranged products in excellent yields. The mild conditions, rapid reaction rates, and suitability for scale up offer immediate practical benefits to access functionalised thiophenols
