A road less travelled: Becoming a rural teacher educator
No full textIn this chapter I seek to bring two relatively under-theorised research fields together: namely rural education and teacher educator professional learning to investigate and better understand the work of becoming a rural teacher educator. I argue that if teacher educators are important to ensuring teachers are well prepared to meet the needs of all students, then rural teacher educators are key to better serving the needs of rural students, their families, and contributing to the sustainability of rural communities more broadly. I do this work by drawing from what Cochran-Smith and Lytle (2009) describe as an ‘inquiry stance’ and through a recursive process examining my own professional learning journey in becoming a rural teacher educator through a self-study inquiry. I use and share my findings from my earlier doctoral studies and return to the ways in which I was ‘unprepared’ as a beginning teacher to teach in a small rural community. I revisit these key themes that emerged now from the vantage point of my research work more recently as a teacher educator. I conclude the chapter with a series of reflections on the ways in which this expanded self-study contributes to the growing knowledge base of becoming a rural teacher educator; professional learning and the implications this work might have for redesigning teacher education curriculum for rural teachers
A comparative study of form and theology in the works of Flannery O'Connor and Simone Weil
No full textIn this comparative study of the form and theology of Flannery O'Connor and Simone Weil I interrogate how Weil's philosophical writings and her theology illuminate O'Connor's use of both narrative and non-fictional forms, and her Catholicism. The Introduction analyses how Weil's concept of superposed reading provides a new method of approaching both O'Connor, her writings, and O'Connor
studies, and focuses on how such apparently different women interconnect. Chapter One explores how both Weil and O'Connor attempt to write their theologies on the
souls of their readers yet are each subject to constraints imposed by form. Weil's concept of locating equilibrium between incommensurates is discussed, and her
distinctively philosophical approach to fictions and fictionality is used to investigate O'Connor's notion of prophetic fictions and the writer's role. Chapter Two assesses how both writers revivify Christian paradoxes. Weil's monstrous concept of affiiction, and O'Connor's use of the grotesque genre to jolt secular man into an
awareness of the sacred are scrutinised. Chapter Three studies how both writers consider an encounter between God and man is possible through the action of grace. My Conclusion interrogates how Weil's work can deepen our understanding of O'Connor's writings, and examines how successful O'Connor is at realising a truly
Christian literature. I conclude that despite being a writer of powerful fictions, O'Connor can not be totally successful in her mission as writer-prophet because
ultimately fiction escapes orthodoxy
“I beg you to tell me what has become of Djamila”: The Political Mobilization of Simone de Beauvoir’s Readers During the Boupacha Affair
No full textBy Sophia Millman This is a condensed version of a Masters thesis dedicated to the political mobilization of Simone de Beauvoir’s readers. The citations from the letters were translated from French by the author. *** On June 2, 1960, the French government ordered all copies of the daily Algiers edition of Le Monde seized and destroyed to suppress the publication of Simone de Beauvoir’s article “Pour Djamila Boupacha.” Beauvoir, a self-professed “woman of letters”, not “of action[1]”, and one ..
Optimal Trajectory Design for SIMONE Mission Study
No full textThis paper deals with the trajectory optimization, through a direct method, for the SIMONE mission study. The mission consists of six identical microsatellites, each targeting a rendezvous with a different type of NEO using low-thrust propulsion both for deep space navigation and for Earth escape phase, departing from an Earth orbit. The direct method used consists of a transcription using polynomial base functions in which trajectory and control laws are reduced to a finite set of unknown states and controls, then a parametric optimization is carried out on these unknowns with an NLP technique. Finally, the optimal trajectory is recovered from these unknown states and controls by a polynomial interpolation. The mission has been conceptually divided in two segments inside the Earth sphere of influence, dealing with the perigee rising and with the escape from Earth gravity field through a Moon gravity assist, and an interplanetary segment, dealing with the transfer to each of the six selected targets. Two different cases were analyzed for each trajectory, one which considers the engine characteristics fixed for the entire mission, and the second which instead considers maximum thrust level and specific impulse dependent on the distance from Sun
Fiber neutrality in fiber-reinforced composites: Evidence from a computational study
No full textWe report numerical evidence for neutrality of thin fibers to a prescribed uniform stress field in a fiber-reinforced composite. Elastic finite element analyses of fiber-reinforced composites are carried out with a conventional fully-resolved model and a novel dimensionally-reduced fiber model.The two modeling approaches are compared in the analysis of mechanical properties and matrix-fiber slip profiles. An analysis of the effectiveness of various fiber orientations with respect to the loading direction shows that the notion of inclusion neutrality, originally formulated for rigid line inclusions by Wang et al. [Journal of Applied Mechanics, 52(4), 814–822, 1985], holds also for linear elastic thin fibers with imperfect interface
Characterization of the structural response of a lithiated SiO<sub>2</sub> / Si interface: A reactive molecular dynamics study
No full textWe report the results of a computational study regarding the mechanical properties of a lithiated Si/SiO2 interface using reactive molecular dynamics. The study is motivated by an intended application of SiO2-coated Sinanotubes as fibers in structural batteries with a fiber-reinforced composite architecture while serving as anodes. According to the results, main failure properties due to partly irreversible bond breakage during mechanical deformation are identified, indicating agreement with bond energy/bond order based estimates. Microscopic failure properties are also identified and interpreted in view of the observed processes of bonding degradation. In particular, the effect of Li distribution on the shear deformation response is evaluated as significant.Applied Mechanic
Accelerating multiscale finite element simulations of history-dependent materials using a recurrent neural network
No full textFE2 multiscale simulations of history-dependent materials are accelerated by means of a recurrent neural network (RNN) surrogate for the history-dependent micro level response. We propose a simple strategy to efficiently collect stress-strain data from the micro model, and we modify the RNN model such that it resembles a nonlinear finite element analysis procedure during training. We then implement the trained RNN model in the FE scheme and employ automatic differentiation to compute the consistent tangent. The exceptional performance of the proposed model is demonstrated through a number of academic examples using strain-softening Perzyna viscoplasticity as the nonlinear material model at the micro level

This duplicity was a mistake by the author: the latter is an erroneous designation and should be disregarded. The only valid paratype lots for M. benthovus are the ones shown above.Published as part of Cavallari, Daniel C., Dornellas, Ana Paula S. & Simone, Luiz Ricardo L., 2016, Second annotated list of type specimens of molluscs deposited in the Museu de Zoologia da Universidade de São Paulo, Brazil, pp. 1-59 in European Journal of Taxonomy 213 on page 10, DOI: 10.5852/ejt.2016.213, http://zenodo.org/record/384012
Was bringt die Föderalismusreform? Wahrscheinliche Effekte der geänderten Zustimmungspflicht
No full textThe recently enacted reform of German federalism is supposed to make legislation faster, more efficient and better. To what extent are these expectations justified? In order to assess the likely effects of the reform, this study uses a research design that was recently applied by the Research and Reference Services of the German Bundestag (parliament): we estimate the future effects of the reform by analyzing the impact it would have had on the legislation in the 14th and 15th term of the Bundestag if it had already been been in force at that time. In particular we ask: To what extent would the number of laws requiring the consent of the states' chamber, the Bundesrat, have been reduced? Which type of laws would have been affected by this reduction - the more controversial ones, or the less controversial ones? Which policy sectors would have seen the greatest reduction? How much would the reduction have increased the government's capacity to act effectively? Would the legislative process have been accelerated? -- Die verabschiedete Föderalismusreform soll die Gesetzgebung in Deutschland schneller, effizienter und besser machen. Inwiefern sind diese Erwartungen berechtigt? Zur Abschätzung der Reformfolgen auf die Bundesgesetzgebung folgen wir in dem vorliegenden Working Paper einer Vorgehensweise, die der Wissenschaftliche Dienst des Bundestages kürzlich in einer Studie angewandt hat: Die Auswirkungen der Föderalismusreform insbesondere auf die Zustimmungspflicht werden anhand der Gesetzgebung der 14. und 15. Legislaturperiode untersucht. Wir fragen insbesondere: Wie stark hätte sich der Anteil der Zustimmungsgesetze verringert, wenn die neuen Zustimmungsregeln schon in diesen beiden Legislaturperioden gegolten hätten? Wären eher zwischen Regierung strittige oder unstrittige Gesetze von der Zustimmungspflicht befreit worden? Welche Politikbereiche wären betroffen? Wie sehr hätte sich die politische Handlungsfreiheit der Bundesregierung erhöht? Wäre die Gesetzgebung durch die veränderten Zustimmungsregeln beschleunigt worden?
A New 3D Tool for Planning Plastic Surgery
No full textFace plastic surgery (PS) plays a major role in today medicine. Both for reconstructive and cosmetic surgery, achieving harmony of facial features is an important, if not the major goal. Several systems have been proposed for presenting to patient and surgeon possible outcomes of the surgical procedure. In this paper, we present a new 3D system able to automatically suggest, for selected facial features as nose, chin, etc, shapes that aesthetically match the patient's face. The basic idea is suggesting shape changes aimed to approach similar but more harmonious faces. To this goal, our system compares the 3D scan of the patient with a database of scans of harmonious faces, excluding the feature to be corrected. Then, the corresponding features of the k most similar harmonious faces, as well as their average, are suitably pasted onto the patient's face, producing k+1 aesthetically effective surgery simulations. The system has been fully implemented and tested. To demonstrate the system, a 3D database of harmonious faces has been collected and a number of PS treatments have been simulated. The ratings of the outcomes of the simulations, provided by panels of human judges, show that the system and the underlying idea are effectiv
