Through a qualitative methodology, the authors interpreted some of the arguments that explain and/or justify certain practices in relation to doubled production, authorship, and coauthorship of academic products. In this paper, the authors present and analyze the results that they obtained after reviewing documents produced by professors and students of six postgraduate programs that are taught in two Mexican public universities. At the same time, the authors examine some of the practices that take place within said programs, given the institutional demands of improving finished studies efficiency. One of the hypotheses of this work is the demands that are imposed by external evaluations of academic processes on professors and their programs in order to reach desirable rates with the purpose of maintaining or increasing the levels of productivity, gives way to certain practices that must be analyzed. This work＇s theoretic framework is constituted by the contributions of career sociology and professional ethics.展开更多

The results show that with the increase of the scaled energy, the number of the closed orbit increases greatly. Some of the orbits are created by the bifurcation of the perpendicular orbit. This case is quite similar to the Rydberg atom in an electric field. When the scaled energy increases furthermore, chaotic orbits appear. This study provides a different perspective on the dynamical behavior of the Rydberg atom near a metal surface.展开更多
