    84 p.En la Cooperativa Abamcoop Ltda., donde se desarrolla esta memoria presenta significativas deficiencias en lo que respecta a la participación de sus socios3, lo cual se refleja en el bajo monto del ahorro promedio de los socios (ver anexo Nº 9). Además la cooperativa no tiene información relevante sobre sus socios, con la cual pueda enfrentar de mejor manera las dificultades que se le presentan como entidad financiera. La baja fidelidad de los socios hacia la cooperativa, ha hecho que estos abandonen sus responsabilidades y dejen de entregar su dinero a la cooperativa. Esta situación es lo que impulsa el desarrollo de esta memoria, la que busca otorgar medidas que cambien esta situación, a través de la entrega de propuestas de estrategias. En los capítulos que componen esta memoria se realiza un análisis, para la utilización de la herramienta tecnológica CROSS SELLING, (o también llamada venta cruzada, la cual es detallada en el capitulo Marco Teórico).La elección de esta técnica es básicamente porque se enfoca a la fidelización de los socios, para poder conseguir una relación de confianza con ellos, y así conseguir que elijan los servicios ofrecidos. Para el desarrollo de esta memoria se utilizo la metodología CRISP-DM (Cross Industry Standard Process for Data Mining) para poder hacer un buen uso de la minería de datos, ya que esta nos fue fundamental para la determinación de los perfiles significativos de los socios. Cabe mencionar que la base de datos de donde fue obtenida la información para el estudio, entregada por la cooperativa, no se encontraba con una cantidad de información deseable para la entrega de resultados mas precisos y certeros. Siendo esto una gran limitante para obtener mejores resultados. 3 Se refiere a que el o los productos que no presentan movimiento en la cuenta capital “Estrategia para la reactivación de Socios a través de la Aplicación de Cross Selling, en la Cooperativa de Ahorro y crédito Abamcoop Ltda.” 10 Universidad de Talca Con la información obtenida en los resultados de esta memoria, logramos determinar ue el producto que prevalece en la mayoría de los socios es el de cuenta cuota de participación, la mayoría de los socios so

    El objetivo de este trabajo fue contribuir al proceso de enseñanza – aprendizaje de conocimientos biológicos e integrarlos al proceso productivo. Se desarrolló en el ámbito de la Escuela de la Familia Agrícola Dr. Ernesto Nazar, Acevedo, Provincia de Buenos Aires. Los destinatarios del proyecto fueron alumnos del ciclo superior de la escuela (31 alumnos). El grupo de voluntarios estuvo integrado por alumnos y docentes del Dpto. Producción Animal, Facultad de Agronomía, Universidad de Buenos Aires. El trabajo se basó en la práctica de campo y se concentró en los procesos biológicos claves del sistema de producción animal bajo estudio: a) el crecimiento del forraje y los cambios estacionales en la oferta de alimento, b) el consumo de alimento bajo pastoreo, c) la transformación del alimento ingerido en leche, d) la extracción de leche de calidad (ordeñe). Consistió en la observación, recopilación y análisis de información y la realización de un diagnóstico del funcionamiento de cada proceso. Adicionalmente, se desarrollaron tres módulos productivos a) crianza y engorde de terneros, b) producción de queso y c) producción de biogas. Se realizaron 51 visitas formales a la Escuela entre agosto 2009 – mayo 2012, el 15% del tiempo se invirtió en tareas de organización y coordinación de actividades con los docentes de la escuela y operarios del tambo y el resto se destinó al trabajo en el aula y de campo. El cronograma de actividades estuvo de acuerdo con la estacionalidad de los procesos biológicos y con el trabajo de campo realizado. El trabajo práctico fortaleció el uso de conocimientos y motivó el interés de los destinatarios por participar en el proceso productivo. Esto se reflejó en el compromiso asumido con el desarrollo de los módulos y el interés puesto en las tareas realizadas en el tambo (ej.: ordeñe). El grupo de voluntarios estuvo conformado por 20 alumnos y 8 docentes, con un máximo de cinco voluntarios y al menos un docente en cada visita. Las dificultades iniciales asociadas al desconocimiento del entorno y falta de experiencia del grupo de voluntarios fueron superadas con éxito. El acceso a la escuela y el trabajo de campo se vieron afectados por las condiciones ambientales y condicionaron tanto el número como la frecuencia de intervenciones. La articulación docencia – extensión enriqueció y nutrió el intercambio entre actores (escuela, universidad, productor)

    Sloan Digital Sky Survey IV: mapping the Milky Way, nearby galaxies, and the distant universe

    Get PDF
    We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is observing hundreds of thousands of Milky Way stars at high resolution and high signal-to-noise ratios in the near-infrared. The Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey is obtaining spatially resolved spectroscopy for thousands of nearby galaxies (median ). The extended Baryon Oscillation Spectroscopic Survey (eBOSS) is mapping the galaxy, quasar, and neutral gas distributions between and 3.5 to constrain cosmology using baryon acoustic oscillations, redshift space distortions, and the shape of the power spectrum. Within eBOSS, we are conducting two major subprograms: the SPectroscopic IDentification of eROSITA Sources (SPIDERS), investigating X-ray AGNs and galaxies in X-ray clusters, and the Time Domain Spectroscopic Survey (TDSS), obtaining spectra of variable sources. All programs use the 2.5 m Sloan Foundation Telescope at the Apache Point Observatory; observations there began in Summer 2014. APOGEE-2 also operates a second near-infrared spectrograph at the 2.5 m du Pont Telescope at Las Campanas Observatory, with observations beginning in early 2017. Observations at both facilities are scheduled to continue through 2020. In keeping with previous SDSS policy, SDSS-IV provides regularly scheduled public data releases; the first one, Data Release 13, was made available in 2016 July

    The 13th Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the SDSS-IV Survey Mapping Nearby Galaxies at Apache Point Observatory

    The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) began observations in July 2014. It pursues three core programs: APOGEE-2,MaNGA, and eBOSS. In addition, eBOSS contains two major subprograms: TDSS and SPIDERS. This paper describes the first data release from SDSS-IV, Data Release 13 (DR13), which contains new data, reanalysis of existing data sets and, like all SDSS data releases, is inclusive of previously released data. DR13 makes publicly available 1390 spatially resolved integral field unit observations of nearby galaxies from MaNGA,the first data released from this survey. It includes new observations from eBOSS, completing SEQUELS. In addition to targeting galaxies and quasars, SEQUELS also targeted variability-selected objects from TDSS and X-ray selected objects from SPIDERS. DR13 includes new reductions ofthe SDSS-III BOSS data, improving the spectrophotometric calibration and redshift classification. DR13 releases new reductions of the APOGEE-1data from SDSS-III, with abundances of elements not previously included and improved stellar parameters for dwarf stars and cooler stars. For the SDSS imaging data, DR13 provides new, more robust and precise photometric calibrations. Several value-added catalogs are being released in tandem with DR13, in particular target catalogs relevant for eBOSS, TDSS, and SPIDERS, and an updated red-clump catalog for APOGEE.This paper describes the location and format of the data now publicly available, as well as providing references to the important technical papers that describe the targeting, observing, and data reduction. The SDSS website, http://www.sdss.org, provides links to the data, tutorials and examples of data access, and extensive documentation of the reduction and analysis procedures. DR13 is the first of a scheduled set that will contain new data and analyses from the planned ~6-year operations of SDSS-IV.PostprintPeer reviewe

    NEOTROPICAL FRESHWATER FISHES: A dataset of occurrence and abundance of freshwater fishes in the Neotropics

    No full text
    The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.
