Spatial graphs and Convolutive Models
2020
In the last two decades, many complex systems have benefited from the use of graph theory, and these approaches have shown robust applicability in the field of finance, computer circuits and in biological systems. Large scale models of brain systems make also a great use of random graph models. Graph theory can be instrumental in modeling the connectivity and spatial distribution of neurons, through a characterization of the relative topological properties. However, all approaches in studying brain function have been so far limited to use experimental constraints obtained at a macroscopic level (e.g. fMRI, EEG, MEG, DTI, DSI). In this contribution, we present a microscopic use (i.e. at the …
Maintaining Dynamic Minimum Spanning Trees: An Experimental Study
2010
AbstractWe report our findings on an extensive empirical study on the performance of several algorithms for maintaining minimum spanning trees in dynamic graphs. In particular, we have implemented and tested several variants of the polylogarithmic algorithm by Holm et al., sparsification on top of Frederickson’s algorithm, and other (less sophisticated) dynamic algorithms. In our experiments, we considered as test sets several random, semi-random and worst-case inputs previously considered in the literature together with inputs arising from real-world applications (e.g., a graph of the Internet Autonomous Systems).
UNITY OF THEORY AND PRACTICE IN THE PROMOTION OF PRESCHOOL CHILD'S MUSICALITY IN THE TEACHER'S AND CHILD'S COLLABORATION
2020
This scientific article involves holism, anthropological and action methodological approaches. The article includes theoretical substantiations based on J.Greata's (2006) concepts of the musical activity impact on the child holistic entirety development, B.Vikmane (1995) and L.Mackevicha's (1999), Latvian preschool music scientists, conceptions about music content and A.Liduma's (2004-2016) researches in the child musicality (emotional responsiveness, musical hearing, sense of rhythm, musical memory and musical thinking, voice vocal range and singing skill) development promotion possibilities through the teacher and the child collaboration in the preschool music sessions. The empiric resear…
Embodied sound design
2018
Abstract Embodied sound design is a process of sound creation that involves the designer’s vocal apparatus and gestures. The possibilities of vocal sketching were investigated by means of an art installation. An artist–designer interpreted several vocal self-portraits and rendered the corresponding synthetic sketches by using physics-based and concatenative sound synthesis. Both synthesis techniques afforded a broad range of artificial sound objects, from concrete to abstract, all derived from natural vocalisations. The vocal-to-synthetic transformation process was then automated in SEeD, a tool allowing to set and play interactively with physics- or corpus-based sound models. The voice-dri…
LINKING TEACHER PROFESSIONAL DEVELOPMENT NEEDS WITH APPROPRIATE SOLUTIONS: INSIGHTS FROM AN INIATIVE IN LATVIA
2021
International surveys have stated that each year teachers spend, on average, more than 10 days engaged in different professional development activities. The purpose for this investment in teacher professional development (TPD) is clear: teachers’ competence must develop according to changes in curriculum and 21st century requirements. In previous research we have developed a theoretical teacher competence framework, implemented it to identify teacher (N=263) groups competence gaps and professional development needs. The goal of this research is to link identified professional development needs related to the instruction of 21st century skills (criteria - instructional design, learning goals…
Capital humain et compétences de base des adultes : production et valorisation
2013
Basic skills are important in current policies because of high costs generated by illiteracy and supported by the society. The aim of the present thesis is to bring a new contribution on this thematic in a microeconomic approach. It consists of two parts. The first one concerns the valorization of basic skills on the labor market, through chapters 1 and 2, while the second one concerns the production of French skills according to the migratory origins, through chapters 3 and 4. Chapter 1 is about the returns to basic skills on the labor market, in terms of overeducation/undereducation and in terms of wages. The central hypothesis is to assume that education, through the diploma, is not a go…
Participatory tools and methods for community action. SESPAS Report 2018
2018
Resumen: La participación es un proceso que requiere la implicación de responsables de la política, del personal directivo y técnico de las instituciones, y de la ciudadanía, así como de la acción intersectorial e interdisciplinaria. Para generar cambios transformadores es necesaria una infraestructura que favorezca la participación y la acción planificada, reconociendo a todos los actores del proceso. Se precisan tiempo y compromiso para su continuidad a través de la producción conjunta de acciones, y de ahí la importancia de consolidar proyectos participativos que continúen más allá de los cambios políticos para que los servicios públicos sean sostenibles. La formación, el uso adecuado de…
Gestión de mano de obra en la empresa pública: el caso de RENFE
2008
Los cambios en las prácticas de gestión de mano de obra que se están aplicando en Renfe en las últimas décadas han conllevado una reducción drástica de la plantilla (flexibilidad en la salida), y una mayor disponibilidad laboral de los que han quedado (flexibilidad funcional). Dichos cambios guardan relación con la orientación privatizadora de la economía que impone un cuestionamiento del modelo de transporte ferroviario existente hasta fechas recientes. Asimismo, están condicionados por el hecho de ser una empresa pública (financiación presupuestaria, politización,...). El objetivo básico de las prácticas de gestión de mano de obra aplicadas en Renfe es la reducción de los costes laborales…
The Regional Effects of Public Spending on Active Labor Market Policies: Evidence from Advanced Economies
2022
This paper examines the regional effects of public spending on Active Labor Market polices (ALMPs). Using an unbalanced sample of 308 regions belonging to 29 OECD Economies for the period 1995-2011, we show that discretionary increases in public spending on active labor market policies at the national level have statistically significant short- and medium-term effect in reducing regional unemployment rate, while raising regional output. These effects tend to be larger during periods of low GDP growth, and when complemented by a larger share of cohesion fund expenditures.
