Recursion at the crossroads of sequence modeling, random trees, stochastic algorithms and martingales

2013

This monograph synthesizes several studies spanning from dynamical systems in the statistical analysis of sequences, to analysis of algorithms in random trees and discrete stochastic processes. These works find applications in various fields ranging from biological sequences to linear regression models, branching processes, through functional statistics and estimates of risk indicators for insurances. All the established results use, in one way or another, the recursive property of the structure under study, by highlighting invariants such as martingales, which are at the heart of this monograph, as tools as well as objects of study.

Analyse numérique MIGS 1re Année

2021

Il s'agit d'un cours d'analyse numérique qui a été dispensé à l'Université de Bourgogne en Master MIGS 1re Année (en 2019-2020, et 2020-2021). Il traite principalement de la résolution itérative de systèmes linéaires symétriques par gradient conjugué, et aussi de la résolution de systèmes linéaires mal posés par moindres carrés. Il vient en complément aux cours d'analyse numérique et d'optimisation que les étudiants ont suivi auparavant.

Moment Map and Gelfand Transform for the Enveloping Algebra

2019

International audience; Describing the Gelfand construction for the analytic states on an universal enveloping algebra, we characterize pure states and re-find the main result of a preceding work with L. Abdelmoula and J. Ludwig on the separation of unitary irreducible representations of a connected Lie group by their generalized moment sets.

The developmental dynamics of task-avoidant behavior and math performance in kindergarten and elementary school

2012

Besides cognitive factors, children's learning at school may be influenced by more dynamic phenomena, such as motivation and achievement-related task-avoidant behavior. The present study examined the developmental dynamics of task-avoidant behavior and math performance from kindergarten to Grade 4. A total of 225 children were tested for their arithmetic skills in kindergarten and in Grades 1, 2, and 4 of elementary school. Children's task-avoidant behavior in learning situations was rated by their teachers. The results of latent growth curve analyses showed that math performance and task-avoidant behavior develop in tandem: an increase in task-avoidant behavior was related to less improvem…

In pursuit of beginning teachers'competence in promoting reading motivation: a mixed-methods study into the impact of a contunuing professional devel…

2020

As teachers’ reading motivation and self-efficacy for promoting reading motivation can be considered vital for their reading-oriented promotive teaching practices and students’ reading motivation, this study evaluated the impact of a year-long CPD program for beginning primary school teachers. A convergent parallel mixed-methods design with repeated measures was established, including a comparison and two CPD conditions (group vs. individually-oriented). Based on the quantitative results only no clear impact of and differences between the conditions could be observed. The qualitative analysis, however, showed growth in teachers’ reading motivation and self-efficacy at a different pace and l…

Exploring Teachers' Motivation for Teaching and Professional Development in Ethiopia : Voices from the Field

2015

Teachers’ work, learning, and professional development are central to any effort aiming at improving schools. Consequently, teachers must consider themselves as a lifelong learner, engage in continuous professional learning and apply that learning to improve student learning and achievement. This article explores teachers’ motivation for teaching and professional development in secondary schools in Ethiopia. Data were collected via interviews and focus group discussions from 32 teachers. The analysis of the collected information revealed low salary and the absence of link between performance and reward as major motivational challenges for teachers. The identified motivational challenges wer…

MOTIVACIÓN Y ESTILO ATRIBUCIONAL SOBRE EL RENDIMIENTO ACADÉMICO EN EDUCACIÓN INFANTIL

2016

El presente trabajo tiene como objetivo examinar el poder predictivo de variables del sistema motivacional sobre las habilidades iniciales de lectura y matemáticas en una muestra de niños de Educación Infantil. Participaron 209 preescolares (5-6 años) y sus maestros. Se evaluaron las  habilidades matemáticas de conteo, conocimiento de los números, cálculo y resolución de problemas. Para determinar el rendimiento en lectura se administraron tareas de identificación de letras y de lectura de palabras. Respecto al sistema motivacional, se analizaron las variables de competencia-motivación, atención-persistencia y actitud hacia el aprendizaje, así como las dimensiones de internalidad, globalida…

The Comparison of Self-Perception of the Use of Learning Strategies in Spanish and Lithuanian Secondary Students When Learning Science

2021

Improving students‘ learning strategies is important for them in order to learn successfully. This article compares the self-perception of the use of learning strategies in Spanish and Lithuanian secondary schools students when learning science and analyse the students understanding of these strategies to determine the sociocultural environment influence on this perception. Results emphasize the need to include support actions to improve the management of strategies in secondary school.

Motivation to Study for PhD Degree: Case of Latvia

2014

AbstractThis paper studies what goals individuals pursue when enrolling in doctoral studies and how it affects the characteristics of the university they find important for choosing it and information sources on doctoral programme they find useful. It uses data collected in 2014 from PhD students and PhD candidates in 14 universities in Latvia and from students born in Latvia but studying abroad. The main result is substantial heterogeneity of goals by field of study, allowing to divide the latter into three groups. Group 1 contains arts & humanities, economics, and education & psychology. Compared to it, students from Group 2 (biology, agriculture, environment & geoscience; physics, mathem…
