Interactions, spillovers de connaissance et croissance des économies modernes. Faut-il préférer la globalisation ou la proximité géographique ?
2009
Globalisation and metropolisation in modern economies induce some locational strategies of knowledge based activities towards cities and deeply increase trade and move of ideas across cities. In that context, we study the way knowledge spillovers have influenced the economic growth of 82 European Metropolises over the 1990-2005 period. We model knowledge spillovers across cities according to three specific interaction patterns depending either on geography or on global advanced services or thought a combination of these patterns. We show that the mixed pattern matters the best for economic growth of cities in Europe.
Identification et caractérisation de candidats d’origine naturelle à action herbicide pour contrôler les adventices
2016
EASPEIPMGESTADAGROSUPINRA; The use of herbicides to control weeds is very common. However, some herbicides are both environmentally detrimental and human unhealthy. The use of microorganisms acting as natural herbicide could be an alternative control method. Symptomatic weeds will be collected in field. Microorganisms will be isolated from symptomatic weeds, purified, identified and inoculated on weeds to confirm Koch’s postulates. The identified pathogenic microorganisms will be tested against a selection of weeds and crops to characterize the host range and the specificity of these microorganisms. In parallel, the diversity of endophytic microorganisms of symptomatic weeds will be charact…
Bacheliers, étudiants et jeunes diplômés : quels systèmes migratoires régionaux ?
2006
Since French Society enters the so-called “Economy of knowledge”, migrations of young people, especially these concerning higher education graduates, are of most interests. Despite the fact that it could help to understand relations between University and work market and ways regions can evolve, the study of migrations of young people was not yet done. A set of results highlights first the main role of French capital region. It shows also main similarities and differencies of migratories' behavior.
Case-specific performance of MM-PBSA, MM-GBSA, and SIE in virtual screening.
2015
In drug discovery the reliable prediction of binding free energies is of crucial importance. Methods that combine molecular mechanics force fields with continuum solvent models have become popular because of their high accuracy and relatively good computational efficiency. In this research we studied the performance of molecular mechanics generalized Born surface area (MM-GBSA), molecular mechanics Poisson-Boltzmann surface area (MM-PBSA), and solvated interaction energy (SIE) both in their virtual screening efficiency and their ability to predict experimentally determined binding affinities for five different protein targets. The protein-ligand complexes were derived with two different app…
Intercultural communication in experience tourism in the Inari area
2011
Tiivistelmä – Abstract Multicultural people both live in and visit the Inari area, where tourism is the main industry. Interaction between tourists and people working in the tourism industry is an essential part of the experience provided to the tourists. The focus of this study is on how multicultural workers in experience tourism in Inari area interact with international tourists. Another focus is how the workers act together as a multicultural team. The empirical part of this study focuses on one company located in the municipality of Inari. The interviews concentrated on gathering stories of both successful as well as challenging events of the interaction and teamwork. The stories were …
Performance Enhancement of a Small Animal Positron Emission Tomograph based on Continuous Crystals and Silicon Photomultipliers
2017
La tomografía por emisión de positrones (PET, por sus siglas en inglés) es una técnica de Medicina Nuclear que permite obtener de manera no invasiva imágenes funcionales “in vivo” marcando un compuesto orgánico con un emisor de positrones. Los tomógrafos PET requieren un alta resolución espacial y sensibilidad para estimar con precisión la distribución del radiotrazador en el animal. Frente a los bloques pixelados comúnmente utilizados en PET, los detectores que consisten en la combinación de cristales continuos acoplados a fotodetectores segmentados pueden ofrecer una mayor eficiencia y una alta resolución espacial. Esta última depende de la precisión de los algoritmos de determinación de …

Soitonopettajan rooli oppimismotivaation vahvistajana taiteen perusopetuksessa : opettajan ja oppilaan välinen vuorovaikutus viulunsoitonopetuksessa …
2017
The aim of this study is to find tools for the instrument teacher to support the student's learning motivation. The research is set in the cultural region of Central Ostrobothnia. The research material consists of a survey conducted by means of a questionnaire, recorded video footage of lessons given by three violin teachers, and a total of eight interviews with these teachers and their students. The data was analyzed using both quantitative and qualitative methods. The study reveals that the most important motivation factor is the sense of relatedness of the pupil. The key factor is a close relationship between the pupil and the teacher, which allows the teacher to engage the pupil in the …

Tempting to Tag : An Experimental Comparison of Four Tagging Input Mechanisms
2010
Tagging helps achieve improved indexing and recommendation of resources (e.g., videos or pictures) in large data collections. In order to reap the benefits of tagging, people must be persuaded to label the resources they consume. This paper reports on a study in which four different tagging input mechanisms and their effect on users’ motivation to tag were compared. The mechanisms consisted of a standard tag input box, a chatbot-like environment, a bookmarking mechanism, and a “tag and vote” game. The results of our experiment show that the use of the nonstandard tagging input mechanisms does not affect users’ motivation to tag. In some instances tagging mechanisms were found to distract us…
