Presentación del Monográfico: una mirada a la emigración española cualificada reciente: Estado de la cuestión y enfoques teóricos
2018
The study of qualified emigration has returned to the political and scientific agendas in recent decades. Currently the theoretical approaches have changed from a completely renewed economic, political, social and technological context. This article presents a summary of these new approaches and a current overview of skilled migration of Spaniards, based on a review of the specialized literature.

The dawning of the theory of equilibrium figures: a brief historical account from the 17th through the 20th century
2014
A brief but complete historical survey of the theory of equilibrium figures from its early origins, dating back to 17th-century, until the latest 20th-century developments, with a view towards its applications, is carried out.
The strange case of Paul Appell's last memoir on Monge's problem: "sur les déblais et remblais"
2016
International audience; We analyze a case of plagiarism that appears in a work published in 1928 by Paul Appell (1855–1930) in the collection Mémorial des sciences mathématiques. Appell's memoir entitled Le problème géométrique des déblais et remblais contains a verbatim copy of several pages from a memoir published in 1886 by Albert de Saint-Germain (1839–1914). By tracing back Appell's last years, we have found historical evidences that might cast a shadow of doubt on Appell's full responsibility by the plagiarism that appeared under his name.
Historical Origins of the nine-point conic -- The Contribution of Eugenio Beltrami
2020
In this paper, we examine the evolution of a specific mathematical problem, i.e. the nine-point conic, a generalisation of the nine-point circle due to Steiner. We will follow this evolution from Steiner to the Neapolitan school (Trudi and Battaglini) and finally to the contribution of Beltrami that closed this journey, at least from a mathematical point of view (scholars of elementary geometry, in fact, will continue to resume the problem from the second half of the 19th to the beginning of the 20th century). We believe that such evolution may indicate the steady development of the mathematical methods from Euclidean metric to projective, and finally, with Beltrami, with the use of quadrat…
Toward a scientific and personal biography of Tullio Levi-Civita (1873–1941)
2005
International audience; Tullio Levi-Civita was one of the most important Italian mathematicians in the early part of the 20th century, contributing significantly to a number of research fields in mathematics and physics. In addition, he was involved in the social and political life of his time and suffered severe political and racial persecution during the period of Fascism. He tried repeatedly and in several cases successfully to help colleagues and students who were victims of anti-Semitism in Italy and Germany. His scientific and private life is well documented in the letters and documents contained in his Archive. The authors' aim is to illustrate the events of his life by means of his …
From the theory of “congeneric surd equations” to “Segre's bicomplex numbers”
2015
We will study the historical pathway of the emergence of Tessarines or Bicomplex numbers, from their origin as "imaginary" solutions of irrational equations, to their insertion in the context of study of the algebras of hypercomplex numbers.
From causal thinking to wisdom and spirituality: some perspectives on a growing research field in adult (cognitive) development
2015
This article concentrates on the latest international trends in the research on psychological development of adults, and especially on the development of cognition. The field of research has been very fragmented, and researchers have kept creating new models one after another to describe their own lines of thought and also seeking for empirical evidence for their models. This has created a rather equivocal picture of the phenomenon itself. The present article attempts to identify the historical roots of the field, and introduces descriptive factors that could conceptually determine the gist of the phenomenon. In this context we will discuss, mainly, research going back to Piaget and Perry, …
Investigating mathematics teacher identity development: A theoretical consideration
2015
International audience; The paper discusses a theoretical framework for investigating the process of becoming a mathematics teacher, based on the need to better understand how mathematics and teaching combine in developing mathematics teacher identities. Identity is understood as a function of participation in and at the boundaries of various communities of practice, during university teacher education and at school. In order to reveal possible relationships between developing teacher identities and the discipline of mathematics, teachers' changing concept images of mathematics are embedded within the definition of identity.
