Wavefront outer scale and seeing measurements at San Pedro Mártir Observatory

The first measurements of the spatial coherence outer scale at the Observatorio Astronómico Nacional at San Pedro Mártir (OAN-SPM) are reported along with long term seeing measurements. These parameters were measured with the Generalized Seeing Monitor and with a Differential Image Motion Monitor. An instrumented mast was also used to measure the structure constant of the refractive index C2 n ...

ar X iv : 0 80 9 . 16 68 v 1 [ as tr o - ph ] 9 S ep 2 00 8 On the nature of the δ Scuti star HD 115520

Observing Delta Scuti stars is most important as their multi-frequency spectrum of radial pulsations provide strong constraints on the physics of the stars interior; so any new detection and observation of these stars is a valuable contribution to asteroseismology. While performing uvby-beta photoelectric photometry of some RR Lyrae stars acquired in 2005 at the Observatorio Astronómico Naciona...

Consideraciones de Cultura Nacional para Interfaces Web

Much has been studied about the effects of Geert Hofstede’s National Culture dimensions. However, regarding Information Systems Research, most works have focused on information technology adoption and use, and impacts on task performance. This research in progress attempts to explore factors that need to be considered for web interfaces design. Multinational firms tend to standardize applicatio...

Plano Nacional De Qualificação Do Trabalhador – Planfor

This article considers that the National Plan of Workers’ Qualification – Planfor established too audacious general objectives: democratization of access to professional qualification; the search of a sustainable development model; and new State’s performance. It also considers that the Plan succeeded in the first and third objectives, while its limits have had great impact on the second one.
