THE TECHNOLOGICAL DIDACTIC KNOWLEDGE OF THE CONTENT (TPACK) IN UNIVERSITY TEACHERS. IMAGES AND MODES OF EXPRESSION IN CLASSROOM PRACTICES

We present preliminary results in the framework of the research project: "The construction of the didactic knowledge of content in experienced teachers and beginners of the National University of the Northeast. Multiple case study "; specifically around the visions that of the Technological Didactic Knowledge of the Content support professors and their complex ways of manifesting in the practices of subjects of Teachers and Degrees of the Faculty of Humanities. In this opportunity, we place the analysis in the images about the use of technologies in teaching and its effective incorporation into a specific didactic cycle. The theoretical proposal that we assume is the Model TPACK (“Technological Pedagogical Content Knowledge”). We adopt as a methodological strategy the study of multiple cases, for its construction we use the review and analysis of professional documents (CV and schedules), semistructured interviews and non-participant observation of classes. The cases are constituted by teachers of three (3) subjects. The predominance of the use of assimilative technologies (support for exposure), it shows a professional culture that has not yet managed to internalize the TPACK model in the academic unit

Estudio de casos múltiples”; específicamente en torno a las visiones que del Conocimiento Didáctico Tecnológico del Contenido sustentan profesores/as y sus modos complejos de manifestarse en las prácticas de asignaturas de Profesorados y Licenciaturas de la Facultad de Humanidades. En esta oportunidad, ubicamos el análisis en las imágenes acerca del uso de las tecnologías en la enseñanza y su incorporación efectiva a un ciclo didáctico concreto. La propuesta teórica que asumimos es el Modelo CDTC (“Conocimiento Didáctico Tecnológico del Contenido”). Adoptamos como estrategia metodológica al estudio de casos múltiples, para su construcción empleamos la revisión y análisis de documentos profesionales (CV y planificaciones), entrevistas semi estructuradas y observación no participante de Clases. Los casos están constituidos por docentes de tres (3) asignaturas. El predominio de uso de las tecnologías asimilativas (apoyo a la exposición), da cuenta de una cultura profesional que aún no ha logrado internalizar el modelo CDTC en la unidad académica

El modelo Tpack en la praxis docente en una universidad argentina: conocimientos y prácticas docentes en torno al conocimiento didáctico-tecnológico del contenido (CDTC) en aulas universitarias

Presentamos una aproximación a los Conocimientos y prácticas docentes en torno al Conocimiento Didáctico-Tecnológico del Contenido (CDTC) o Technological Pedagogical Content Knowledge (TPACK) en aulas universitarias de carreras humanísticas en una universidad argentina.Metodológicamente, construimos un caso múltiple constituido por equipos docentes de seis asignaturas vinculadas con Tecnología educativa de Profesorados y Licenciaturas de una de las Unidades Académicas. También, realizamos una doble triangulación: intra-metodológica (fuentes primarias y secundarias) y de investigadores y docentes participantes como estrategia de validación pertinente en un estudio cualitativo.Encontramos que las maneras de abordar la relación teoría-práctica devienen envariadas configuraciones del CDTC, según las trayectorias profesionales de las profesoras y entramados de experiencias de formación permanente, gestión e investigación. Configuraciones construidas individualmente y re-construidas colectivamente en los territorios disciplinaresacadémicos y diferentes contextos.act We present an approach to the Knowledge and teaching practices around the Technological Pedagogical Content Knowledge (TPACK) or Conocimiento Didáctico-Tecnológico del Contenido (CDTC) in university classrooms of humanistic careers in an Argentine university. Methodologically, we built a multiple case consisting of teaching teams of six subjects linked to the Educational Technology of Teachers and Degrees from one of the Academic Units. Also, we perform a double triangulation: intra - methodological (primary and secondary sources) and of participating researchers and teachers as a relevant validation strategy in a qualitative study. We find that the ways of approaching the theory-practice relationship come in various configurations of the TPACK, according to the professional trajectories of the teachers and networks of experiences of permanent training, management and research. Configurations built individually and collectively re-built in the disciplinary-academic territories and different contexts.Fil: Flores, Fernando Agustin Santiago. Universidad Nacional del Nordeste.

Prognostic value of proadrenomedullin in severe sepsis and septic shock patients with community-acquired pneumonia

Principles: Midregional proadrenomedullin (proADM) is a novel biomarker with potential prognostic utility in patients with community-acquired pneumonia. The aim of this study was to investigate the value of proADM levels for severity assessment and outcome prediction in severe sepsis and septic shock due to CAP. Methods: Prospective observational study including 49 patients admitted to ICU with both a clinical and radiologic diagnosis of pneumonia and fulfilling criteria for severe sepsis or septic shock. The prognostic accuracy of proADM levels was compared with those of pneumonia severity index and of procalcitonin (PCT) and C-reactive protein (CRP). Results: 49 patients with severe sepsis or septic shock due to CAP were included in the study. Mortality was 24.5% for ICU and 34.7% for hospital mortality. In all cases proADM values at ICU admission were pathological (considering normal proADM levels <4 nmol/L). ProADM consistently rose as PSI class advanced from II to V (p = 0.02). Median proADM levels were higher (p <0.01) in hospital non-survivors 5.0 (1.9-10.1) nmol/L vs. survivors 1.7 (1.3-3.1) nmol/L. These differences were also significant with respect to ICU mortality. The receiver-operating characteristic curve for proADM yielded an AUC of 0.72; better than the AUC for PCT and CRP (0.40 and 0.44 respectively) and similar to PSI (0.74). Conclusions: In our study MR-proADM levels correlate with increasing severity of illness and death. High MR-proADM levels offer additional risk stratification in high-risk CAP patients.Funding / potential competing interests: Borja Suberviola has received remuneration for lectures on the topic of inflammation markers by BRAHMS Iberia, Spain.

Planeamiento estratégico para la Empresa WESCON S.A.

En el presente documento se elabora el Plan Estratégico para la Empresa WESCON S.A.. Este plan estratégico es elaborado bajo un exhaustivo análisis de factores internos y externos, utilizando como herramientas principales diferentes matrices (i.e MEFE, MPC, FODA, Intereses de la Organización, RUMELT, entre otras) los cuales nos permitirán identificar las principales Fortalezas, Oportunidades, Debilidades y Amenazas de la empresa, siendo el objetivo del estudio establecer los objetivos de corto y largo plazo que deben estar alineados con la estrategia de la empresa y a su vez con la visión a largo plazo de WESCON S.A. El sector construcción, al cual pertenece la empresa WESCON S.A., viene creciendo los últimos diez años, posicionándolo inclusive como el mejor escenario de los últimos 50 años el país. Esto origina un escenario más que atractivo para la empresa, reforzado aún más con la alta demanda insatisfecha en el mercado, producto de la escasez de inmuebles y terrenos urbanos a nivel país. Las estrategias propuestas en el planeamiento estratégicos se centran en diseñar y desarrollar productos para los polos emergentes fuera de la ciudad de Lima, formar asociaciones empresariales para generar nuevos mercados, desarrollar servicio post venta a fin de generar la sostenibilidad del negocio, mejorar la estructura del área de marketing, implementar un plan de crisis y continuidad del negocio, convocar inversionistas extranjeros a fin de generar mayor banco de tierras, tener un plan de expansión y el desarrollo de planes de retenciones para el personal que trabaja en WESCON S.AThis summary is to draw up the Strategic Plan for company WESCON S.A., based on a comprehensive analysis of internal and external factors using different matrixes as main tools such as MEFE, MPC, FODA, Organizational Interests, RUMELT, among others. Thus, we will be enabled to identify the main company’s Strengths, Opportunities, Weaknesses and Threats. The study is aimed at establishing short-term and long-term purposes that must be consistent with the company strategy and, at the same time, with WESCON S.A. long-term vision. The construction sector, of which WESCON S.A. is part, is growing during the last ten years, positioning it even as the best scenario of the last 50 years in the country. This creates an attractive scenario for the company, strengthened by the highest market unsatisfied demand, as a result of the lack of real estate properties and urban lands within the country. The strategies proposed in the strategic plan are focused on designing and developing products for the emerging sectors outside the city of Lima; setting up business partnerships in order to promote new markets; developing post-sale services in order to generate business sustainability; improving the marketing area structure; implementing a crisis plan and business continuity; calling for foreign investors to create a bigger bank of land; counting on an expansion plan and developing plans to retain WESCON S.A. employeesTesi

Techniques for measuring aerosol attenuation using the central laser facility at the Pierre Auger Observatory

The Pierre Auger Observatory in Malargue, Argentina, is designed to study the properties of ultra-high energy cosmic rays with energies above 10(18) eV. It is a hybrid facility that employs a Fluorescence Detector to perform nearly calorimetric measurements of Extensive Air Shower energies. To obtain reliable calorimetric information from the FD, the atmospheric conditions at the observatory need to be continuously monitored during data acquisition. In particular, light attenuation due to aerosols is an important atmospheric correction. The aerosol concentration is highly variable, so that the aerosol attenuation needs to be evaluated hourly. We use light from the Central Laser Facility, located near the center of the observatory site, having an optical signature comparable to that of the highest energy showers detected by the FD. This paper presents two procedures developed to retrieve the aerosol attenuation of fluorescence light from CLF laser shots. Cross checks between the two methods demonstrate that results from both analyses are compatible, and that the uncertainties are well understood. The measurements of the aerosol attenuation provided by the two procedures are currently used at the Pierre Auger Observatory to reconstruct air shower data

The rapid atmospheric monitoring system of the Pierre Auger Observatory

The Pierre Auger Observatory is a facility built to detect air showers produced by cosmic rays above 10^17 eV. During clear nights with a low illuminated moon fraction, the UV fluorescence light produced by air showers is recorded by optical telescopes at the Observatory. To correct the observations for variations in atmospheric conditions, atmospheric monitoring is performed at regular intervals ranging from several minutes (for cloud identification) to several hours (for aerosol conditions) to several days (for vertical profiles of temperature, pressure, and humidity). In 2009, the monitoring program was upgraded to allow for additional targeted measurements of atmospheric conditions shortly after the detection of air showers of special interest, e. g., showers produced by very high-energy cosmic rays or showers with atypical longitudinal profiles. The former events are of particular importance for the determination of the energy scale of the Observatory, and the latter are characteristic of unusual air shower physics or exotic primary particle types. The purpose of targeted (or "rapid") monitoring is to improve the resolution of the atmospheric measurements for such events. In this paper, we report on the implementation of the rapid monitoring program and its current status. The rapid monitoring data have been analyzed and applied to the reconstruction of air showers of high interest, and indicate that the air fluorescence measurements affected by clouds and aerosols are effectively corrected using measurements from the regular atmospheric monitoring program. We find that the rapid monitoring program has potential for supporting dedicated physics analyses beyond the standard event reconstruction

A search for anisotropy in the arrival directions of ultra high energy cosmic rays recorded at the Pierre Auger Observatory

Observations of cosmic rays arrival directions made with the Pierre Auger Observatory have previously provided evidence of anisotropy at the 99% CL using the correlation of ultra high energy cosmic rays (UHECRs) with objects drawn from the Veron-Cetty Veron catalog. In this paper we report on the use of three catalog independent methods to search for anisotropy. The 2pt-L, 2pt+ and 3pt methods, each giving a different measure of self-clustering in arrival directions, were tested on mock cosmic ray data sets to study the impacts of sample size and magnetic smearing on their results, accounting for both angular and energy resolutions. If the sources of UHECRs follow the same large scale structure as ordinary galaxies in the local Universe and if UHECRs are deflected no more than a few degrees, a study of mock maps suggests that these three method can efficiently respond to the resulting anisotropy with a P-value = 1.0% or smaller with data sets as few as 100 events. using data taken from January 1, 2004 to July 31, 2010 we examined the 20, 30, ... , 110 highest energy events with a corresponding minimum energy threshold of about 49.3 EeV. The minimum P-values found were 13.5% using the 2pt-L method, 1.0% using the 2pt+ method and 1.1% using the 3pt method for the highest 100 energy events. In view of the multiple (correlated) scans performed on the data set, these catalog-independent methods do not yield strong evidence of anisotropy in the highest energy cosmic rays

Antennas for the detection of radio emission pulses from cosmic-ray induced air showers at the Pierre Auger Observatory.

The Pierre Auger Observatory is exploring the potential of the radio detection technique to study extensive air showers induced by ultra-high energy cosmic rays. The Auger Engineering Radio Array (AERA) addresses both technological and scientific aspects of the radio technique. A first phase of AERA has been operating since September 2010 with detector stations observing radio signals at frequencies between 30 and 80 MHz. In this paper we present comparative studies to identify and optimize the antenna design for the final configuration of AERA consisting of 160 individual radio detector stations. The transient nature of the air shower signal requires a detailed description of the antenna sensor. As the ultra-wideband reception of pulses is not widely discussed in antenna literature, we review the relevant antenna characteristics and enhance theoretical considerations towards the impulse response of antennas including polarization effects and multiple signal reflections. On the basis of the vector effective length we study the transient response characteristics of three candidate antennas in the time domain. Observing the variation of the continuous galactic background intensity we rank the antennas with respect to the noise level added to the galactic signal
