El género epistolar en la prensa como visión ciudadana de la esfera pública en Colombia

A partir de un análisis temático inductivo, este artículo explora la visión ciudadana sobre la esfera pública expresada en las cartas de los lectores de los diarios El Tiempo y El Heraldo de Colombia. Los resultados muestran cómo la identidad colectiva de los lectores apareció en forma transversal en las cartas, para dar cuenta de una comunidad de adultos que se autodefine como “colombianos de bien”. El análisis reveló dos unidades de significado: posturas sobre la administración de lo público y antagonismos en la esfera pública, centrada en el conflicto político con las guerrillas. A través de estas se pudieron hacer visibles los llamamientos vívidos de los lectores al gobierno, funcionarios públicos, actores al margen de la ley y a sus compatriotas, para movilizarse para exigir cambios sociales largamente esperados.

Who is in charge? An L2 Discourse Intonation Study on Four Prosodic Parameters to Exert the Pragmatic Function of Dominance and Control in the Context of L2 Non-specialist Public Speaking

This paper reports the findings from a study of the learning of English intonation by Spanish speakers within the discourse mode of L2 oral presentation. The purpose of this experiment is, firstly, to compare four prosodic parameters before and after an L2 discourse intonation training programme and, secondly, to confirm whether subjects, after the aforementioned L2 discourse intonation training, are able to match the form of these four prosodic parameters to the discourse-pragmatic function of dominance and control. The study designed the instructions and tasks to create the oral and written corpora and Brazil’s Pronunciation for Advanced Learners of English was adapted for the pedagogical aims of the present study. The learners’ pre- and post-tasks were acoustically analysed and a pre / post- questionnaire design was applied to interpret the acoustic analysis. Results indicate most of the subjects acquired a wider choice of the four prosodic parameters partly due to the prosodically-annotated transcripts that were developed throughout the L2 discourse intonation course. Conversely, qualitative and quantitative data reveal most subjects failed to match the forms to their appropriate pragmatic functions to express dominance and control in an L2 oral presentation.

Raman Analysis of Dilute Aqueous Samples by Localized Evaporation of Submicroliter Droplets on the Tips of Superhydrophobic Copper Wires

Raman analysis of dilute aqueous solutions is normally prevented by their low signal levels. A very general method to increase the concentration to detectable levels is to evaporate droplets of the sample to dryness, creating solid deposits which are then Raman probed. Here, superhydrophobic (SHP) wires with hydrophilic tips have been used as supports for drying droplets, which have the advantage that the residue is automatically deposited at the tip. The SHP wires were readily prepared in minutes using electroless galvanic deposition of Ag onto copper wires followed by modification with a polyfluorothiol (3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluoro-1-decanethiol, HDFT). Cutting the coated wires with a scalpel revealed hydrophilic tips which could support droplets whose maximum size was determined by the wire diameter. Typically, 230 μm wires were used to support 0.6 μL droplets. Evaporation of dilute melamine droplets gave solid deposits which could be observed by scanning electron microscopy (SEM) and Raman spectroscopy. The limit of detection for melamine using a two stage evaporation procedure was 1 × 10^-6 mol dm^-3. The physical appearance of dried droplets of sucrose and glucose showed that the samples retained significant amounts of water, even under high vacuum. Nonetheless, the Raman detection limits of sucrose and glucose were 5 × 10^-4 and 2.5 × 10^-3 mol dm^-3, respectively, which is similar to the sensitivity reported for surface-enhanced Raman spectroscopy (SERS) detection of glucose. It was also possible to quantify the two sugars in mixtures at concentrations which were similar to those found in human blood through multivariate analysis.

SERS of meso-droplets supported on superhydrophobic wires allows exquisitely sensitive detection of dipicolinic acid, an anthrax biomarker, considerably below the infective dose

Surface-enhanced Raman measurements of <1 μL analyte/colloid meso-droplets on superhydrophobic wires with hydrophilic tips allowed dipicolinic acid, a spore biomarker for Bacillus anthracis (anthrax), to be detected at 10(-6) mol dm(-3). This is equivalent to 18 spores, significantly below the infective dose of 10(4) spores and 2 orders of magnitude better than previous measurements.

From Scarcity to Overload: Finding “Good Enough” Public Information in Myanmar’s Transition Information Symposium Summary Report

The Myanmar Book Aid Preservation Foundation (MBAPF) and Enlightened Research Myanmar (EMR) held an Information Symposium titled, From Scarcity to Overload: Finding “Good Enough” Public Information in Myanmar’s Transition in Yangon, Myanmar on January 28-29, 2016. The Symposium was co-sponsored by the University of Washington’s Henry M. Jackson School of International Studies (JSIS) and the Technology & Social Change Group (TASCHA) of the University’s Information School with support from the United States Agency for International Development (USAID), Microsoft, the Bill & Melinda Gates Foundation, and the Asia Foundation. The Information Symposium was held as part of a larger project supported by USAID, Microsoft, the Bill & Melinda Gates Foundation, and the Tableau Foundation implemented by the University of Washington’s JSIS and TASCHA, along with Myanmar partners, MBAPF and EMR. This project, Information Strategies for Societies in Transition, was developed largely because of the staggering challenges Myanmar is facing as it seeks to “catch-up” in the world’s most economically competitive region.

The role of musical aptitude in the pronunciation of English vowels among Polish learners of English

It has long been held that people who have musical training or talent acquire L2 pronunciation more successfully than those that do not. Indeed, there have been empirical studies to support this hypothesis (Pastuszek-Lipińska 2003, Fonseca-Mora et al. 2011, Zatorre and Baum 2012). However, in many of such studies, musical abilities in subjects were mostly verified through questionnaires rather than tested in a reliable, empirical manner. Therefore, we run three different musical hearing tests, i.e. pitch perception test, musical memory test, and rhythm perception test (Mandell 2009) to measure the actual musical aptitude in our subjects. The main research question is whether a better musical ear correlates with a higher rate of acquisition of English vowels in Polish EFL learners. Our group consists of 40 Polish university students studying English as their major who learn the British pronunciation model during an intense pronunciation course. 10 male and 30 female subjects with mean age of 20.1 were recorded in a recording studio. The procedure comprised spontaneous conversations, reading passages and reading words in isolation. Vowel measurements were conducted in Praat in all three speech styles and several consonantal contexts. The assumption was that participants who performed better in musical tests would produce vowels that are closer to the Southern British English model. We plotted them onto vowel charts and calculated the Euclidean distances. Preliminary results show that there is potential correlation between specific aspects of musical hearing and different elements of pronunciation. The study is a longitudinal project and will encompass two more years, during which we will repeat the recording procedure twice to measure the participants’ progress in mastering the English pronunciation and comparing it with their musical aptitude.

Results from New Zealand's 2014 report card on physical activity for children and youth

BACKGROUND: This brief report provides grades for the 2014 New Zealand Report Card on Physical Activity for Children and Youth. The Report Card presents a review of current evidence across 9 key indicators, including physical activity (PA), organized sport and free play, sedentary behavior, and community and government initiatives across New Zealand. METHODS: Nationally representative survey data were collated by researchers at the University of Auckland, New Zealand, between June and December 2013. The grade for each indicator is based on the percentage of children and youth meeting a defined benchmark: A is 81%-100%; B is 61%-80%; C is 41%-60%, D is 21%-40%; F is 0%-20%; INC is incomplete data. RESULTS: Overall PA received a score of B, as did Organized Sport Participation and Active Play. PA participation in School Environment scored slightly less with a score of B-. Sedentary Behaviors, Family and Peers, and Community and Built Environment scored a grade of C. Active transportation received a score of C-. An inconclusive grade was given for the Government indicator due to a lack of established international criteria for assessment. CONCLUSIONS: PA participation in New Zealand is satisfactory, but could improve. However, sedentary behavior is high. Of particular concern is the age-related decline in PA participation, particularly among adolescent females, and the increase in sedentary behavior.

A graduate piano recital : an analytical study

The purpose of this thesis is to provide a historical and musical analysis that illustrates characteristic features of musical compositions from the Baroque, Classical, Romantic, and Twentieth century styles. The structural analysis of the pieces reveal the evolution in the musical expression regarding line, texture, form, and the technical skills employed by the composers through polyphonic, homophonic, and twelve-tone procedures. The works of this recital represent four different styles: The prelude and fugue among the important forms of the Baroque style; the sonata embodying the principles of balance and unity of the Classical style; the etude and waltz as representative of the Romantic style; and the nocturne as an illustration of the transformation of the melody, harmony, and rhythm in the music of the 20thcentury.
