This brief article is devoted to a critique of the arguments put forward by the Attorney General of Canada in connection with the Reference concerning certain questions relating to the secession of Quebec (hereinafter, "the Reference"). This critique will not be presented from a plainly positivist standpoint. On the contrary, I will be examining in particular (1) how the approach taken by the Attorney General impoverished the legal concepts of the rule of law anf federalism, both of which were, however, central to her submission; and, in a more general way, (2) how the excessively detailed analysis of constitutional texts contributes to the impoverishment of the symbolic function of the law, however essential that dimension may be to its legitimacy. My criticism will take into account the reasons for judgement delivered recently by the Supreme Court in the Reference.

Isoscalar collective modes in a relativistic meson-nucleon system are investigated in the framework of the time-dependent Thomas-Fermi method. The energies of the collective modes are determined by solving consistently the dispersion relations and the boundary conditions. The energy weighted sum rule satisfied by the models considered allows the identification of the giant resonances. The percentage of the energy weighted sum rule exhausted by the collective modes is in agreement with experimental data, but the agreement with the energy of the modes depends on the model considered.

The paper will consist of three parts. In part I we shall present some background considerations which are necessary as a basis for what follows. We shall try to clarify some basic concepts and notions, and we shall collect the most important arguments (and related goals) in favour of problem solving, modelling and applications to other subjects in mathematics instruction. In the main part II we shall review the present state, recent trends, and prospective lines of development, both in empirical or theoretical research and in the practice of mathematics instruction and mathematics education, concerning problem solving, modelling, applications and relations to other subjects. In particular, we shall identify and discuss four major trends: a widened spectrum of arguments, an increased globality, an increased unification, and an extended use of computers. In the final part III we shall comment upon some important issues and problems related to our topic.
