Defining as discursive practice in transition – Upper secondary students reinvent the formal definition of convergent sequences
2018
International audience; The investigation of limits is at the heart of analysis at university. Accordingly, it is a worthwhile topic for transition courses. The present study engages upper secondary students in reinventing the definition of convergent sequences. Using a commognitive framework, the central development stages of the definition from experiential to abstract are empirically investigated in terms of activated secondary school discourses. The students' familiarity with secondary school discourses is critical, as it allows them to transition from grasping processes with metaphors towards grasping them as formal and abstract objects. For this, school objects act as intermediate s…
Defining relations of minimal degree of the trace algebra of 3 X 3 matrices
2008
The trace algebra Cnd over a field of characteristic 0 is generated by all traces of products of d generic n × n matrices, n, d 2. Minimal sets of generators of Cnd are known for n = 2 and n = 3 for any d as well as for n = 4 and n = 5 and d = 2. The defining relations between the generators are found for n = 2 and any d and for n = 3, d = 2 only. Starting with the generating set of C3d given by Abeasis and Pittaluga in 1989, we have shown that the minimal degree of the set of defining relations of C3d is equal to 7 for any d 3. We have determined all relations of minimal degree. For d = 3 we have also found the defining relations of degree 8. The proofs are based on methods of representati…
Formaciones sociales y opresión en Marx
2018
The text explains the difference between Marx?s concept of «oppression» and others as «coercion» by Durkheim or «domination» by Weber. The article then establishes, in a methodical way, the centrality of a passage from Capital, in which three different theories on «oppression» appear. It?s explained that two of them are rather a philosophical antinomy. The other, relative to the heteronomy of social time, can be completed by defining the heteronomy of social space, which gives it analytical virtuality. Some examples are given.
De participació local. Una proposta metodològica desde la investigació-acció-participativa
2018
Citizen participation is an increasingly prevalent term in our society. In the process of deployment in the municipal area, progressively local corporations make efforts to innovate practices and develop experiences of citizen participation in defining policies and public affairs, and allocating budgets. While innovation has been advanced with regard to the tools and mechanisms to be used to promote participation, many of the initiatives and experiences have focused more on the implementation of the vote than in the different social processes inherent in the participation. Moreover, we are faced with the absence of a methodological guide that allows approaching a project or strategic plan o…
