Intimately Bound to Numbers: On the Rhetorics of GLBTQ School Climate Research
Authors: Thorpe Justin N. , Greteman Adam J. 
Published: February 2015

Abstract
The GLBTQ research community has become, in some ways, bound to using quantification within their arguments about the changes that are being recommended for schools and the lives of GLBTQ youth. This article considers the rhetorical nature of quantification when arguing for such changes. This article draws from the Gay, Lesbian, and Straight Educational Network’s 2009 National School Climate Survey report, a report that has become central to the discourses concerning GLBTQ youth, including use in television, news media, and academic research. This article begins by considering the nature of rhetoric and how quantification has come to play such an important part in social science writing and argumentation. The article then critiques how quantificational rhetoric is deployed as a tool of fear, guilt, safety and accountability as evidenced in the National School Climate report.
The Square-Root Rule for Reinsurance: Further Analysis and Consideration of China’s Market
Authors: Du Nan , Zeng Zhangrong , Viswanathan Krupa 
Published: February 2015

Abstract
China has been experiencing rapid development in its insurance market in recent years, with its reinsurance market also in a developing stage. Previous theoretical work using a game theory approach suggests that the appropriate number of companies in the insurance market should be the square root of the number of insurers (index = 0.5). To verify the validity of this square-root rule, we conduct an analysis using data over a period. To examine this relationship between the number of insurers and the number of reinsurers, we perform regression analyses using data from the Organization for Economic Cooperation and Development (OECD). We find that the level of the index fluctuates around an index level of 0.4, instead of 0.5, the optimal value by theory. We also observe that this index level fluctuation behaves similar to the price of risk and the property–liability combined ratio. In our analysis, we then replace the number of reinsurers and number of insurers by ceded premium and net premium, respectively, and find similar results. By comparing and calculating these theoretical relationships, we present two formulas of the average size of the reinsurance market with our interpretations on the gap between the theory and the data. In addition, we analyze the Chinese reinsurance market to offer more evidence of our interpretation.
Three open questions in experimental syntax
Authors: Sprouse Jon 
Published: February 2015

AbstractThis article presents a review of current research in experimental syntax, with a focus on three open questions and the (methodo)logical tools that have been developed to explore them. The three questions are: (1) Are the published data underlying syntactic theories valid?, (2) How can we determine the source of acceptability judgment differences?, and (3) What do gradient judgments tell us about the architecture of the grammar? The hope is that these three questions will illustrate the fundamental connection between experimental syntax and theoretical syntax, provide concrete demonstrations of the value of the tools of experimental syntax (e.g., random sampling, factorial logic, and gradient judgments), and point to new directions for future research.

Published: February 2015

ABSTRACTWe developed a new GaN on SiC growth method by metalorganic vapour phase epitaxy (MOVPE) using of a single 2-dimension-growth step. Prior to epitaxy, to inhibit pre-reaction of Si-face SiC substrate with TMGa and NH3, TMAl was flowed without NH3. 1.5 μm of undoped crack-free GaN was grown on 6H-SiC (Si-face). Without buffer layer, the vertical resistance of GaN/SiC structure was found to be around 82.1Ω as determined by I-V characteristic. Further reduction in vertical resistance is expected by growth of n-GaN (1.5μm)/SiC structure (300μm). We also expect a SiC-based GaN heterostructure vertical FET will achieve high power and high switching speed performance.
Impact of Nitridation on Structural and Optical Properties of Epitaxial GaN Films Grown on M-Plane Sapphire by PAMBE

Published: February 2015

ABSTRACTGaN epilayers were grown on m-plane (10-10) sapphire substrates using plasma assisted molecular beam epitaxy. Impact of nitridation on structural and optical properties of GaN film was investigated. The film grown on a nitridated surface resulted in a nonpolar (10-10) orientation while without nitridation caused a semipolar (11-22) orientation. The high resolution X-ray diffraction studies confirmed the orientation of the GaN films. X-ray rocking curve showed better crystallinity of semipolar as compared to nonpolar GaN. Atomic force microscopy showed smoother films in case of nonpolar GaN which might be in account of the nitridation treatment. Room temperature photoluminescence study showed nonpolar GaN to have higher value of compressive strain as compared to semipolar GaN film, which was further confirmed by room temperature Raman spectroscopy. Despite the fact that it is difficult to obtain high-quality nonpolar material due to the planar anisotropic nature of the growth mode, we hereby report the development of non-polar GaN of usable quality, on an m-plane sapphire, involving controlled steps of nitridation.

Published: February 2015

ABSTRACTWe study the thermodynamical properties and lattice dynamics of two-dimensional crystalline membranes, such as graphene and related compounds, in zero temperature limit, where quantum effects are dominant. We find out that, just as in the high temperature classical limit, a fundamental role is played by the anharmonic coupling between in-plane and out-of plane lattice modes, which leads to a strong reconstruction of the dispersion relation of the out-of-plane mode. We identify a crossover temperature, T*, bellow which quantum effects are dominant. We estimate that for graphene T* ∼ 70 - 90 K. Inclusion of anharmonic effects makes the thermal expansion finite in the thermodynamic limit, and below T* it tends to zero as a power law as T→0 as required by the third law of thermodynamics. The specific heat also goes to zero as a power law as T→0, but with a exponent that differs from the one predicted by the harmonic theory.

Published: February 2015

ABSTRACTWe use the combinatorial sputter technique to simultaneously sputter HfO2 and Al2O3 targets to obtain a film of HfxAl1-xOy of specific compositions. The effect of oxide thickness, oxide composition (i.e. Hf:Al ratio) and oxygen gettering layer thickness on DC sweep based resistive switching performance of RRAM is investigated. The oxide thickness primarily affects forming voltage and causes the memory window to increase for the thinnest oxide (6 nm, other thicknesses – 12 nm, 18 nm). The composition of oxide has a non-linear effect on the memory window (high to low resistance ratio) and variability of resistance states whereas the variability of set voltage improves significantly for ternary oxide compared to individual binary oxides. Finally, electrode interlayer for oxygen-gettering is also critical where a thin Ti layer of 1.5nm maintains the memory window but reduces variability in HRS, LRS, reduces Vset and Vreset and improves the variability in Vset.

Published: February 2015

ABSTRACTWe present a detailed study of memory performance of titanium oxide (TiO2-x)-based resistive switching memories by modifying critical parameters of the films involved in the memory stack grown by reactive sputtering at room temperature. The device includes a Ti nanolayer at the Au/TiO2-x interface and it is defined by the following material stack: Au/Ti/TiO2-x/Au/SiO2/Si. We investigate the memory performance optimization of the device in terms of the Ti nanolayer thickness using as a starting point for the TiO2-x growth conditions these identified by varying the ratio of oxygen concentration to argon concentration by our previous results. Due to the superb ability of Ti to absorb oxygen atoms from the dielectric matrix, a large amount of oxygen vacancies is created, which are crucial for the stable function of the memory devices. We observe the existence of an optimum Ti thickness that if further increased gradually degrades the resistive switching behavior. The induced interface oxide thickness is found also to affect the fluctuation of the ON/OFF processes. In terms of electrical performance self-rectifying characteristics were recorded for all samples in the both resistance states. We then demonstrate that at least five-level resistance states could be obtained by modifying the compliance current, exhibiting excellent resistance uniformity and retention capability. The results are supported by C-AFM measurements demonstrating the scaling potential of the large area device discussed above.
Tailoring Industrial Scale CNT Production to Specialty Markets
Authors: Schauer Mark W. , White Meghann A. 
Published: February 2015

AbstractThe vast majority of industrial scale Carbon Nanotube (CNT) production involves short nanotubes (< 100 microns) that appear as a powder. These products are typically utilized as minor components (usually less than 2%) in polymers where they may or may not impart marginal improvements in composite properties. At Nanocomp Technologies we produce large-format CNT material by floating catalyst chemical vapor deposition. This technique produces very long CNTs (> 1 mm) in the gas phase, where entanglement produces large format material of exceptional strength and electrical conductivity. By manipulating the physics and chemistry of the process, the format and properties of the material can be controlled. Post-production processing further enhances the desired material properties. In this way applications such as Armor, Wiring and Cables for aerospace, and Integrated Energy Storage can be realized.
Unipolar resistive switching behavior of high-k ternary rare-earth oxide LaHoO3 thin films for non-volatile memory applications

Published: February 2015

ABSTRACTRare-earth oxides have attracted considerable research interest in resistive random access memories (ReRAMs) due to their compatibility with complementary metal-oxide semiconductor (CMOS) process. To this end we report unipolar resistive switching in a novel ternary rare-earth oxide LaHoO3 (LHO) to accelerate progress and to support advances in this emerging densely scalable research architecture. Amorphous thin films of LHO were fabricated on Pt/TiO2/SiO2/Si substrate by pulsed laser deposition, followed by sputter deposition of platinum top electrode through shadow mask in order to elucidate the resistive switching behavior of the resulting Pt/LHO/Pt metal-insulator-metal (MIM) device structure. Stable unipolar resistive switching characteristics with interesting switching parameters like, high resistance ratio of about 105 between high resistance state (HRS) and low resistance state (LRS), non-overlapping switching voltages with narrow dispersion, and excellent retention and endurance features were observed in Pt/LHO/Pt device structure. The observed resistive switching in LHO was explained by the formation/rupture of conductive filaments formed out of oxygen vacancies and metallic Ho atom. From the current-voltage characteristics of Pt/LHO/Pt structure, the conduction mechanism in LRS and HRS was found to be dominated by Ohm’s law and Poole-Frenkel emission, respectively.

Published: February 2015

ABSTRACTNanoscale systems combining colloidal quantum dots with plasmonic antennas will pioneer the development of novel nanodevices with tailored optical features for a wide range of applications. The interactions between such nanoparticles strongly depend on the particular distance. We propose the use of an atomic force microscope (AFM) to image and to position quantum dots with respect to plasmonic particles. Additionally, we analyze the arrangements with several optical characterization methods, such as confocal microscopy, fluorescence microscopy and superresolution optical fluctuation imaging (SOFI). These methods support each other and improve the AFM manipulation technique. The AFM tip is perfectly aligned to a focused laser by detecting the Raman signal of the silicon tip. Thus ultimately, we can simultaneously use the topography information with a spatial resolution in the range of the nanoparticle sizes and cross-correlate it with the optical characterization methods.

ABSTRACTWe propose some chemical processing procedures for fabricating thin films in Hf-Zr-O system by a unique film deposition technique using supercritical carbon dioxide fluid (scCO2), i.e., supercritical fluid deposition (SCFD), which would be an prospective approach for fabricating metal-oxide films for integrated circuits because of its unique characteristics; e.g., extraction ability, transportation capability, and reaction equilibrium etc., are quite favorable for the film deposition from metal-complex precursors.The SCFD was accomplished in a closed batch-type reaction apparatus, consisting of two steps; (a) material deposition and (b) subsequent post-treatment under scCO2 atmosphere. Thin films of amorphous Hf-Zr-O were deposited on platinized silicon [(111)Pt/TiO2/(100)Si] substrates by SCFD using metal-complex precursors M[OCH(CH3)]2(C9H11O2)2 (M = Hf or Zr) at reaction temperature of 100 – 300 °C, significantly lower than those for MOCVD. These films possessed dielectric permittivity’s of approximately 20 – 25, comparable to those from conventional processes, although they still included residue of organic species that prompt the dielectric degradation under lower-frequency bias application.

ABSTRACTIn this work, the annealing effects at 180°C in Aluminum-ZnO contacts as function of time were studied. Also, the application in TFTs of ZnO films obtained at low-temperature (200°C) are presented. The ZnO films obtained by ultrasonic Spray Pyrolysis at 200 °C were deposited over Aluminum contacts on SiO2/Si wafers to demonstrate the use of active layer in thin-film transistors. The results show that an improvement can be obtained in metal-ZnO interfaces by low-temperature annealing treatments. However, long annealing time degrade the metal-ZnO interface and may affect the electrical performance of the device.

Published: February 2015

ABSTRACTGraphene oxide (GO) is one of the most attractive inorganic nanofillers in proton exchange membranes (PEMs) for its large specific surface area and high proton conductivity. The proton conductivity of GO nanosheet is known to be orders of magnitude greater than the bulk GO, thus it is essential to improve the dispersion of GO nanosheets in the PEM matrix to achieve higher conductivity. In this study, we report a facile and effective method to fabricate a GO/sulfonated poly ether ether ketone (SPEEK) composite membrane with well-dispersed GO nanosheets in SPEEK matrix by using electrospinning technique for direct methanol fuel cell application. The composite membrane exhibits improved proton conductivity, dimensional stability and methanol barrier property due to the presence of well-dispersed GOs. It is believed that the GO nanosheets can not only induce continuous channels for proton-conducting via Grotthuss mechanism, but also act as methanol barriers to hinder the methanol molecules from passing through the membrane.
Fragmentation as universality: The fear to hyper information in the society of knowledge/La fragmentación como universalidad: el miedo a la hiperinformación en la sociedad del conocimiento
Authors: Jiménez Batista Robin 
Published: February 2015

Este artículo de reflexión propone una revisión a los conceptos: Sociedad de la ignorancia, Sociedad del desconocimiento y sociedad de la incultura. Se intenta demostrar cómo estos conceptos propuestos por los expertos Antoni Brey, Daniel Innerarity y Goncal Mayos responden a una corriente que enfrenta el determinismo tecnológico desde el determinismo sociológico, desconociendo el desarrollo desigual de los pueblos, las desigualdades entre la periferia y el centro y, por otra parte, desconocen que la recepción de la información se produce en consonancia con la fragmentación de la contemporaneidad y la multiplicidad de sentidos que esta encarna. Finalmente, nos ocuparemos en reflexionar cómo lo universal enfrenta el concepto de totalidad que arguyen estos y otros autores para aterrorizarse frente a la hiperinformación y la incapacidad de comprender las mediaciones.
The Science of Culture: Implications for Social Science Inquiries into Contemporary African Phenomenon/La ciencia de la cultura: implicaciones para las investigaciones de las Ciencias Sociales en el fenómeno africano contemporáneo
Authors: Hyman Sundjata ibn 
Published: February 2015

Este artículo discute la cultura como una unidad de análisis dentro de la investigación en las ciencias sociales y su tratamiento más sistemático como un modelo dinámico e idiosincrático para el desarrollo humano, modelo cuya disposición lógica de axiomas interpretativos de “estructuras profundas” cosmológicas y ontológicas (axiomas de existencia para la organización colectiva y su funcionamiento) configura el objetivo y la naturaleza de conductas y praxis sociales abiertas (incluyendo símbolos, lengua, costumbres) e informa un plan general de vida que guía el comportamiento individual y las prácticas colectivas. Este enfoque conductista permite una rica elaboración de la cultura aclarando sus fundamentos cosmológicos, ontológicos y psicológicos, y las influencias en su naturaleza y papel en la formación, organización y funcionamiento de conglomerados humanos. Además, ofrece un examen de las implicaciones teóricas para la estabilidad social en axiomas antitéticos de estructura profunda, los cuales fragmentan una previa existencia social teleológica dentro de un arreglo de símbolos y rituales sociales fragmentarios lista parala cosificación. Y, a través de ello, se propone cómo el fenómeno contemporáneo de la globalización –y el paradigma económico neoclásico que lo sustenta—engendra un modelo de la realidad y del vivir idiosincrático basado en lo económico, modelo que no es ni una conceptualización humana comúnmente compartida, ni un objetivo universal deseado.
Chronotopic Juxtaposition in “Añejo cinco siglos”/Yuxtaposición cronotópica en “Añejo cinco siglos”
Authors: Parra Ericka 
Published: February 2015

El tiempo y el espacio se interconectan en el cuento “Añejo cinco siglos” de la colección Apenas murmullos (2004). MaríaElena Llana (1936), la periodista y escritora cubana, utiliza una yuxtaposición a través del crono. La escritora trae al presentedos personajes femeninos de diferentes épocas. Una es la gallega Doña Isabel de Bobadilla (del tiempo pasado) y otraes la mulata Chabela (del tiempo presente). Ambos personajes femeninos tienen un diálogo que interconecta dos tiempos y espacios diferentes. Ellas crean intersecciones geográficas, políticas y personales, específicamente porque sus hombres han dejado la Habana bajo diferentes circunstancias pero con el mismo objetivo de establecerse en Florida. Don Hernando de Soto continúa la expedición española hacia tierra firme dejando a Isabel con el corazón roto mientras Lazarito ha salido en una balsa prometiéndole a Chabela que regresaría. Así, el propósito de este ensayo es demostrar que las diarias interconexiones personales son cronotopos que reconfiguran las condiciones ilegales de cruzar las fronteras geográficas e históricas. No obstante, en estas circunstancias personales ambas mujeres reconfiguran las narrativas del poder político y erótico.
The Construction of Characters in Roald Dahl´s Cinderella: A Systemic Functional Linguistic Analysis/La construcción de los personajes en “Cinderella” de ROALD DAHL: un análisis desde la Lingüística Sistémico Funcional
Authors: Rezzano Norma Susana 
Published: February 2015

Los cuentos infantiles constituyen un recurso mediante el cual las culturas construyen y transmiten valores, que se expresan típicamente en los comportamientos de los personajes. En sus versiones publicadas bajo el título Revolting Rhymes (2008), el autor galés Roald Dahl desafía los valores transmitidos en algunos cuentos infantiles tradicionales. Este trabajo muestra la forma en que tal cuestionamiento se manifiesta en la construcción de los personajes de Cinderella de Dahl, mediante un análisis lingüístico Sistémico-Funcional (Halliday and Mathiessen 2004). Para ello, se exploran los patrones de transitividad en los que los personajes principales están involucrados y se realiza un análisis comparativo con una versión tradicional de este cuento. El análisis revela interesantes diferencias, especialmente en la construcción de los roles femeninos y masculinos.
