4. The impact of the incubator on the internationalization of firms - Machado, Raquel Engelman; Zen, Aurora Carneiro; Fracasso, Edi Madalena
This paper aims to examine how technology incubators contribute to the internationalization of incubated Brazilian companies. To do so, was developed a framework that, in addition to supporting research, can be used to provide a basis for studies of internationalization in small technology-based companies and incubators and to assist their managers. By comparing the factors identified as influencing internationalization and the actions and services provided by the technology incubators, an integrated model with four constructs (entrepreneurs; organizational characteristics; network; foreign market) was built. The results demonstrate that incubation positively affects the internationalization of companies and indicate the actions and services...

5. Auroral emission at Jupiter, through Juno's UVS eyes - Grodent, Denis; Bonfond, Bertrand; Gladstone, G.; Gérard, Jean-Claude; Gustin, Jacques; Radioti, Aikaterini; Dumont, Maïté; Palmaerts, Benjamin; The Juno Science Team
Juno’s orbit insertion around Jupiter will take place in little bit more than one year (July 2016). After a 107-day capture orbit (Oct. 2016), it will perform a series of 33 eleven-day science polar orbits offering unprecedented views of the auroral regions of Jupiter. The science payload of Juno includes an UltraViolet Spectrograph (UVS) that will characterize the UV auroral emissions of Jupiter over all science orbits. It will obtain high-resolution images and spectra that will provide context for Juno’s in situ particles and fields measurements in the larger polar magnetosphere with Juno’s JADE and JEDI detectors. At the same...

Peer reviewed

7. Auroral emissions at Jupiter and Saturn, at the crossroads of Astrophysics Geophysics and Plasma Physics - Grodent, Denis
Auroral physics is at the intersection of more general fields of physics such as Astrophysics, Geophysics and Plasma Physics. In particular, the giant planets Jupiter and Saturn may be seen as slow rotating pulsars. For these two planets, there is a direct link between this pulsar-like behaviour and the auroral processes that are taking place in their atmosphere. We will take the example of Jupiter to illustrate haw the aurora is generated in the magnetosphere as a result of the volcanic activity of the moon Io.

8. At the heart of Jupiter’s aurora; at the crossroads of Astrophysics Geophysics and Plasma Physics - Grodent, Denis
Auroral physics is at the intersection of more general fields of physics such as Astrophysics, Geophysics and Plasma Physics. In particular, the giant planets Jupiter and Saturn may be seen as slow rotating pulsars. For these two planets, there is a direct link between this pulsar-like behaviour and the auroral processes that are taking place in their atmosphere. We will take the example of Jupiter to illustrate haw the aurora is generated in the magnetosphere as a result of the volcanic activity of the moon Io. The ultraviolet aurora of Jupiter is conveniently described in terms of components located inside...

9. Search for Satellite Effects on Saturn's Auroras in Cassini UVIS Data - Pryor, Wayne; Espositio, Larry; Jouchoux, Alain; Grodent, Denis; Gustin, Jacques; Radioti, Aikaterini
The Cassini Ultraviolet Imaging Spectrograph (UVIS) has been obtaining Saturn auroral images since 2004. We have previously reported instances when the main auroral oval brightened briefly in a quasi-periodic fashion near the sub-Mimas longitude. Here we examine the large set of UVIS auroral images obtained from close range and high sub-spacecraft latitudes. We will plot the brightness of the individual auroral measurements (and binned auroral measurements) as a function of local time, and as a function of the location of Mimas and other moons to test for any correlations. Mimas, while a relatively small moon, exerts a strong influence on...

10. Hubble Space Telescope observations of variation of the O I 135.6 nm/ O I 130.4 nm ratio in Ganymede’s atmosphere - Molyneux, P. M.; Nichols, J. D.; Bannister, N. P.; Bunce, E. J.; Clarke, J. T.; Cowley, S. W.; Grodent, Denis; Milan, S. E.; Paty, C.
We present new high-sensitivity HST/COS measurements of the atmospheric O I 135.6 nm/ O I 130.4 nm ratio at Ganymede, which we show exhibits significant spatial and temporal variability. Specifically, the ratios observed on Ganymede’s leading hemispheres vary between 2.14±0.03 and 2.67±0.02, while on the trailing hemisphere the ratios are observed to be between 0.98±0.02 and 1.53±0.03. These high-sensitivity observations increase the signal to noise of these measurements by an order of magnitude over previous HST/STIS observations of the same [1], thus confirming that the temporal variation suggested by these previous observations is real. The emissions are excited through electron-impact...

11. Characteristics of Jupiter's auroral acceleration region - Ray, Licia; Gustin, Jacques; Grodent, Denis
Jupiter’s dynamic auroral region is the signature of magnetosphere-ionosphere coupling. The magnetospheric drivers of the emission are relatively well understood, yet the high-latitude characteristics of the interaction have not been measure in-situ. Ahead of Juno’s arrival next summer, we use HST STIS observations of Jupiter’s auroral emission to infer the location of Jupiter’s auroral acceleration region and the properties of the precipitating auroral electrons. We analyze two images of Jupiter’s northern emission, determining the precipitating electron energy and incident energy flux for the main aurora, Io spot, Ganymede footprint, and flare regions. The resulting relationships between energy flux and electron...

12. Characterization of stream - aquifer interaction in carbonate rocks - Briers, Pierre; Sohier, Catherine; Schmit, Flore; Hallet, Vincent; Descy, Jean-Pierre; Orban, Philippe; Degré, Aurore; Brouyère, Serge
Groundwater - surface water interactions play a fundamental role in terms of quantity and quality of water and in terms of ecological quality of rivers. Despite many research efforts and the necessity to better understand such interactions in order to reach effective management of water resources, stream-aquifer exchanges remain poorly understood, in particular in fractured carbonate environments.

13. Precariedad y defensa de los derechos laborales de los inmigrantes mexicanos en la reestructuración productiva - Rocha Romero, David
La flexibilización de los medios de producción está presentando oportunidades para las empresas que emprenden procesos de desconcentración productiva, pero al mismo tiempo modifica las relaciones laborales, presentando una mayor precariedad en los empleos: estancias discontinuas, ausencia de contratos, nula o mínima protección del Estado, salarios inestables y bajos, condiciones de inseguridad e insalubralidad, trato injusto y discriminación. Los trabajadores urbanos de baja calificación. El presente artículo muestra ejemplos de precariedad laboral de los inmigrantes mexicanos en la segunda ciudad más importante del estado de Illinois, Aurora, así como sus estrategias para paliar la situación. Los resultados plasmados en el...

17. Estrategias metodológicas para la investigación del usuario en los medios sociales: análisis de contenido, teoría fundamentada y análisis del discurso - González Teruel, Aurora
Content analysis, the constructivist version of grounded theory and discourse analysis of discursive psychology are analyzed in the context of research on how users generate and share information on social media. For each of the three designs, the research question, methods of data analysis and research output are studied. This combination of three methodologies is valuable to gain knowledge about the user in that environment, defining the object of study from various aspects of user interaction with information.
