César Vallejo y la vanguardia en las fronteras del idioma (Dossier: Literaturas de la integración, el Sur y su diversidad)
No full textEl autor explora el efecto poético, en el caso de los vanguardistas peruanos, que tiene la inclusión de palabras extranjeras en un texto literario. Puesto que se trata de palabras ininteligibles o apenas inteligibles, tal uso remite al tipo de afasia como desorden del eje metafórico, que afecta la similitud/diferencia del lenguaje. Lauer se pregunta por qué los poetas vanguardistas recurrieron al uso de palabras de origen extranjero. En este sentido, interesa al autor destacar los cruces entre modernidad, “tecno terminología” y “extranjería del discurso”, entre cosmopolitismo y conocimiento local. Sostiene Lauer que adoptar una palabra de otro idioma “expresa el deseo de cortar con las fuentes mismas de una tradición, y constituye una crítica a una sensibilidad dada”. El autor indaga en torno a los usos poéticos de palabras de origen extranjero, desde una visión que atiende los sentidos que ellas despliegan, así como también sus aspectos gráficos, sonoros y comunicacionales.The author explores the poetic effect that has the inclusion of foreign words in a literary text in the case of the Peruvian vanguard writers. Since they are unintelligible or barely intelligible words, their usage refers us to the type of aphasia that comes from a disorder in the metaphoric axis, which affects the similarity/difference of language. Lauer reflects on why the vanguard poets resorted to the use of foreign words. In this sense, he is interested in highlighting the overlapping among modernity, “techno terminology” and “foreignicity of discourse”, and between cosmopolitanism and local knowledge. Lauer holds that taking on a word from another language “expresses the desire of severing from the sources of a tradition, and is a criticism to a given sensitivity”. The author reflects about the poetic uses of foreign words from a point of view that focuses on the senses they unfold, as well as the graphic, sound, and communicational aspects

The Level-Set Flow of the Topologist’s Sine Curve is Smooth
No full textAbstract
In this note we prove that the level-set flow of the topologist’s sine curve is a smooth closed curve. In Lauer (Geom Funct Anal 23(6): 1934–1961, 2013) it was shown by the second author that under the level-set flow, a locally connected set in the plane evolves to be smooth, either as a curve or as a positive area region bounded by smooth curves. Here we give the first example of a domain whose boundary is not locally connected for which the level-set flow is instantaneously smooth. Our methods also produce an example of a nonpath-connected set that instantly evolves into a smooth closed curve
Managing Dynamics of Power and Learning in Community Development: A Case Study of Iowan Farmers in Uganda
No full textExtension professionals facilitate community development through the strategic manipulation of learning and power in peer-to-peer learning partnerships. We discuss the relationship between empowerment and power, highlight relevant literature on the difficulties power presents to learning and the efficacy of service learning tools to facilitate mutual learning and present original findings from our research on an international development partnership in which Extension professionals had partial success in creating opportunities for mutually empowering learning among farmers from Iowa and Uganda. We recommend that Extension professionals encourage learning across power gradients by providing opportunities for informal conversations and encouraging reflection by participants.This article is published as “Managing Dynamics of Power and Learning in Community Development: A Case Study of Iowan Farmers in Uganda” Journal of Extension June 2015, Vol 53, No. 3 (co author Stephen Lauer).

The effects of strain on carrier transport in thin and ultra-thin SOI MOSFETs
No full textThesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2005.Includes bibliographical references (leaves 85-91).Thin-body MOSFET geometries such as fully-depleted SOI and double-gate devices are attractive because they can offer superior scaling properties compared to bulk and thick-body SOI devices. The electrostatics of a MOSFET limit how short of a gate length can be achieved before the gate loses control over the channel. In bulk-like devices, the device designer keeps the gate in control with gate oxide scaling and doping profile design. In thin-body geometries, silicon thickness is a new, powerful scaling parameter. Much like with gate oxide scaling, the electrostatics improve with thinner films. This means that the limits of scaling thin-body devices are closely tied with the limits of scaling silicon film thickness. Electrical transport appears to be one of the limiting factors for scaling body thickness. As the silicon film thickness is reduced into the ultra-thin regime, where the film is thinner than the bulk inversion layer thickness, quantum confinement effects begin to be observed. For the most part, these effects act to degrade mobility, reducing performance and making further scaling less rewarding. This work focuses on finding methods to maintain good mobility in ultra-thin silicon films. Thin and ultra-thin body relaxed SOI and biaxially strained SOI MOSFETs were constructed and measured with and without the application of mechanical uniaxial strain to examine the interaction between strain and thin-film effects.(cont.) The band splitting induced by the application of strain is found to at least partially mitigate the mechanisms responsible for degrading electron mobility in ultra-thin films. Additionally, the enhancement seen with uniaxial strain is found to further enhance mobility in biaxially strained films. Finally, the effective mass change caused by uniaxial strain is found to cause the mobility modulation to have a directional dependence, especially in already biaxially strained films.by Isaac Lauer.Ph.D
