    La presente investigaci贸n, se centra en c贸mo la factura electr贸nica, est谩 afectando las actividades y tareas que desarrollan las empresas, espec铆ficamente en el 谩rea administrativa financiera contable, desde un enfoque de sistemas socio-t茅cnico, estudiando la herramienta en sus aspectos organizacionales, administrativos y tecnol贸gicos; y tendiendo a cumplir con los siguientes objetivos: General: - Conocer c贸mo han actuado las organizaciones frente a la factura electr贸nica, para luego proponer una forma 鈥渋deal" de integraci贸n de la factura electr贸nica a los sistemas de informaci贸n de una empresa que les permita aprovechar todos sus beneficios. Espec铆ficos: - Relevar todos aquellos factores que motivaron a las empresas a la aplicaci贸n y uso de la facturaci贸n electr贸nica y las intenciones futuras de continuar operando con este sistema. - Identificar los beneficios que trae aparejado el uso de la factura electr贸nica dentro de las empresas, en especial los relacionados con su integraci贸n a los sistemas de informaci贸n. - Conocer cu谩l ha sido el grado de intervenci贸n de los profesionales contadores en la decisi贸n y dentro del proceso de implementaci贸n de esta herramienta. - Identificar problemas surgidos a profesionales en la implementaci贸n de factura electr贸nica y relevar las soluciones existentes a las problem谩ticas identificadas; - Analizar el circuito de la factura electr贸nica en las distintas 谩reas de una empresa y compararlo con el de la factura tradicional. - Proporcionar mejoras a la actual forma de utilizaci贸n de factura electr贸nica.Fil: Artola, Mat铆as Eduardo.

    International audienceWe present the results from four stellar occultations by (486958) Arrokoth, the flyby target of the New Horizons extended mission. Three of the four efforts led to positive detections of the body, and all constrained the presence of rings and other debris, finding none. Twenty-five mobile stations were deployed for 2017 June 3 and augmented by fixed telescopes. There were no positive detections from this effort. The event on 2017 July 10 was observed by the Stratospheric Observatory for Infrared Astronomy with one very short chord. Twenty-four deployed stations on 2017 July 17 resulted in five chords that clearly showed a complicated shape consistent with a contact binary with rough dimensions of 20 by 30 km for the overall outline. A visible albedo of 10% was derived from these data. Twenty-two systems were deployed for the fourth event on 2018 August 4 and resulted in two chords. The combination of the occultation data and the flyby results provides a significant refinement of the rotation period, now estimated to be 15.9380 卤 0.0005 hr. The occultation data also provided high-precision astrometric constraints on the position of the object that were crucial for supporting the navigation for the New Horizons flyby. This work demonstrates an effective method for obtaining detailed size and shape information and probing for rings and dust on distant Kuiper Belt objects as well as being an important source of positional data that can aid in spacecraft navigation that is particularly useful for small and distant bodies
