ResumoEste artigo apresenta, em uma abordagem qualitativa, um estudo de caso no qual descreve uma proposta pedagógica realizada por estudantes de Cálculo Numérico de uma instituição de nível superior do sul do país. A proposta foi desenvolvida segundo os pressupostos teóricos da pesquisa como princípio pedagógico e teve como objetivo identificar a percepção dos estudantes quanto à compreensão do significado de um conceito ao aprenderem como utilizá-lo em um contexto específico de sua vivência acadêmica. Com base nos trabalhos e testemunhos apresentados, e em Wittgenstein, este estudo mostra que as condições de sentido e significado dos conceitos matemáticos abordados em Cálculo Numérico podem ocorrer quando o estudante conhece diferentes usos desses conceitos em seus respectivos cursos de graduação ou futura profissão.Palavras Chave: Cálculo Numérico, Jogos de Linguagem, Pesquisa como Princípio Pedagógico.AbstractThis article presents, in a qualitative approach, a case study in which it describes a pedagogical proposal carried out by students of Numerical Calculus at a higher education institution in the south of the country. The proposal was developed according to the theoretical assumptions of the research as a pedagogical principle and aimed to identify the students' perception regarding the understanding of the meaning of a concept when learning how to use it in a specific context of their academic experience. Based on the works and testimonies presented and on Wittgenstein, it shows that the conditions of sense and meaning of the mathematical concepts covered in Numerical Calculus can occur when the student knows their different uses in their respective undergraduate courses or future profession.Keywords:  Numerical calculus, Language games, Research as a pedagogical principle.ResumenEste artículo presenta, en un enfoque cualitativo, un estudio de caso en el que describe una propuesta pedagógica llevada a cabo por estudiantes de Cálculo Numérico en una institución de educación superior en el sur del país.

This paper is concerned with the least squares estimation of drift parameters for the Cox–Ingersoll–Ross (CIR) model driven by small symmetrical α-stable noises from discrete observations. The contrast function is introduced to obtain the explicit formula of the estimators and the error of estimation is given. The consistency and the rate of convergence of the estimators are proved. The asymptotic distribution of the estimators is studied as well. Finally, some numerical calculus examples and simulations are given.

We introduce here some books belonging to the Library of the Istituto Lombardo. They are mathematical 16th century editions. The authors, considered at that time mathematician, were indeed devoted to fields of learning that can be barely classified with modern criterions. They studied the basics of numbers theory, of classical geometry, some optical measurements and other fields today belonging to independent branches of learning. Peculiarly some concepts such as the ones of logarithm or power (of a number) came from remote culture. It’s very important to remember that the still used roman numbering constituted an obstacle to the development of the numerical calculus. Essentially we want here to present some precious books very interesting for editorial quality and singularity of contents of some authors whose name are wellknown until today. What we really want/intend is to promote the drawing up of a critical catalogue of our antiquarian scientific library.
