Negotiating for meaning: Papers on foreign language teaching and testing
No full textPapers from a conference on language teaching and testing are grouped in four sections. The first contains a foreword by Dale A. Koike and Antonio R. M. Simoes. The second, on research in second/foreign language teaching, includes the following: "Second Language Learning and Evaluation: From Theory to Classroom Practice" (Sandra J. Savignon); "What Should Portuguese Language Teaching Do About Grammar? Current Trends in the Teaching of Spanish" (Bill Vanpatten); "The Politics of Methodology: Recent Trends and the Teaching of 'Other' Languages" (Diane Musumeci); and "Recent Research on Second Language Learners: Beliefs and Anxiety" (Elaine K. Horwitz). Section three, on reading in a foreign language, presents: "Reading as a Classroom Activity: Theory and Techniques" (Richard Kern, Janet Swaffar, Dolly Young); and "Teaching and Testing an Expository Text" (James F. Lee). The fourth section focuses on Portuguese language teaching for Spanish speakers, with: "Nasal Vowels, the Case of Brazilian Portuguese and Spanish: Description and Classroom Application" (Antonio R.

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Articular cartilage with intra and extrafibrillar waters - Simulations of mechanical and chemical loadings by the finite element method
No full textIn line with previous constitutive developments, a three-phase multi-species electro-chemo-mechanical model of articular cartilage that accounts for the effect of two water compartments is pursued. Here, a finite element formulation is presented in order to solve initial and boundary value problems and to simulate the time and space heterogenous fields generated by mechanical and chemical loadings in laboratory samples. The formulation capitalizes upon (1) the chemo-mechanical model in Loret and Simoes [B. Loret, F.M.F. Simoes, Articular cartilage with intra- and extra-fibrillar waters. A chemo-mechanical model, Mech. Mater. 36 (5-6) (2004) 515-541; B. Loret, F.M.F. Simoes, Mechanical effects of ionic replacements in articular cartilage. I. The constitutive model, Biomech. Model.

Mechanobiol. 4 (2-3) (2005) 81-99] which was restricted to successive equilibria, and from which both time and space were excluded; and (2) the model in Loret and Simoes (B. Loret, F.M.F. Simoes, Articular cartilage with intra- and extra-fibrillar waters. Mass transfer and generalized diffusion, Eur. J. Mech.-A/Solids 26 (1995) 759-788], where the equations of mass transfer between the two fluid phases and the generalized diffusion equations in the extrafibrillar phase have been established. A thin cartilage layer, laterally confined, is loaded through time varying mechanical and chemical conditions applied on the lower and upper boundaries. Two types of chemical loadings are simulated. First the concentration of NaCl in the bath in contact with the cartilage is changed according to several time schemes, including in particular free swelling and cyclic changes. A more complex process consists in replacing NaCl by CaCl2. Chemical loading gives rise to heterogeneous fields during a transient period, whose extend depends on geometry and on a number of characteristic material properties, e.g. Darcy's seepage time, Fick's diffusion time, and typical times for intercompartmental mass transfer. Mechanical confined compression and swelling tests are simulated as well. Spatial profiles of the various chemical species and mechanical, chemical and electrical entities highlight the influences of the existence of two water compartments. At steady state, the strains, stresses, pressures and the distribution of water and ions in the two compartments obtained in Loret and Simoes [B. Loret, F.M.F.

On a question of Pełczyński about strictly singular operators
No full textWe exhibit new examples of weakly compact strictly singular operators with dual not strictly cosingular and characterize the weakly compact strictly singular surjections with strictly cosingular adjoint as those having strictly singular bitranspose. We then obtain new examples of super-strictly singular quotient maps and show that the strictly singular quotient maps in Kalton–Peck sequences are not super-strictly singular
High-pressure metamorphism in Taiwan: from oceanic subduction to arc-continent collision?
No full textThermal Process Lethality Calculator (F-value)
No full textThe paper presents two Python-based calculators for determining the F-value, a measure of the lethality of a thermal process in food safety. Utilizing both the Trapezoidal rule and Simpson's rule for numerical integration, the calculators compute the integral of the lethal rate over time. The inclusion of the Z-value is considered, enabling adjustments to the lethal rate based on temperature deviations.Source code and usage instructions are available in the GitHub repository, "Thermal-Process-Lethality-Calculator-F-value-"
Separation and Visualization of Low Abundant Ubiquitylated Forms
No full textIn this protocol we describe the separation and visualization of ubiquitylated forms of the yeast mitofusin Fzo1 by Western blot. To this aim, we express HA-tagged Fzo1 in Saccharomyces cerevisiae, break the cells to extract a membrane-enriched fraction, solubilize the membranes using detergent and then specifically immunoprecipitate the tagged protein using anti-HA affinity beads. Subsequently, we separate the higher molecular weight (ubiquitylated) forms of Fzo1 via SDS-PAGE. Finally, immunoblotting and immunodecoration are used to detect the protein and its ubiquitylated forms using an HA-specific antibody. By using this protocol, it is possible to separate and visualize higher molecular weight forms of low abundant proteins such as Fzo1 and detect sharp and distinct bands above the unmodified protein by Western blot.s.a.

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
