Albanian students’ motives for preferring certain real-life situations for learning mathematics
2011
This article reports on a qualitative investigation of Albanian students’ motives for preferring certain real-life situations to be used in school mathematics, and possible connections of these motives to characteristics and issues within Albanian society. It is based on realistic interviews with students from Grades 8 and 9 in a school in the district of Shkodra in northern Albania. Interviews were conducted after students experienced five teaching units which dealt with mathematics embedded in real-life situations. Results are expressed in terms of contextmechanism-outcome configurations as proposed by critical realist theory. Most of the resultsare supported by those from a previous quan…
Clinical assessment and comparison of ACL reconstruction using synthetic graft (Neoligaments versus FiberTape).
2021
Background Due to the low potential for primary biological healing of the anterior cruciate ligament (ACL), the most popular approach is currently reconstruction using a graft. Recent research indicates that the technique of strengthening a damaged ligament with synthetic tapes (internal bracing) may be an alternative to reconstructive treatment, especially in cases of partial ACL damage. Objectives To compare and evaluate the possibility of using a synthetic graft (Neoligaments or FiberTape) to treat partial lesions of the ACL. Material and methods This was a retrospective cohort study. Selected from a pool of 128 patients undergoing primary unilateral intra-articular ACL reconstruction du…
Measuring, comparing and interpreting phenotypic selection on floral scent
2022
Natural selection on floral scent composition is a key element of the hypothesis that pollinators and other floral visitors drive scent evolution. The measure of such selection is complicated by the high-dimensional nature of floral scent data and uncertainty about the cognitive processes involved in scent-mediated communication. We use dimension reduction through reduced-rank regression to jointly estimate a scent composite trait under selection and the strength of selection acting on this trait. To assess and compare variation in selection on scent across species, time and space, we reanalyse 22 datasets on six species from four previous studies. The results agreed qualitatively with prev…
Can we increase children’s rights endorsement and knowledge?: A pilot study based on the reference framework of competences for democratic culture
2022
This pilot study is the first to examine whether a novel curriculum based on the Reference Framework of Competences for Democratic Culture (RFCDC) could increase children’s endorsement and knowledge of children’s rights. We conducted a pre-test-post-test design with an intervention and a comparison school. Pupils (n = 172) from Bulgaria, Italy, Norway, Romania, and Spain attended schools in which the curriculum was taught, whereas pupils in the comparison group (n = 120) attended schools in the same city where the curriculum was not taught. Both groups were tested on their endorsement and knowledge of rights before and at the end of the intervention. Children in the intervention group incre…
Adaptive range-based localization algorithm based on trilateration and reference node selection for outdoor wireless sensor networks
2022
Locating the nodes of outdoor wireless sensor networks (WSNs) using (tri)lateration with a low-cost ranging technique, such as the received signal strength indicator (RSSI), often results in inaccurate location estimates. This can mostly be explained by the combined effect of distance estimate errors and localization geometry, both of which are subject to the reference nodes used. To develop techniques for reducing localization error, the distance estimate errors and localization geometry must be analyzed and taken into account. To address these challenges, this paper aims to seek ways to improve the quality of range-based trilateration localization for WSN nodes in varying outdoor conditio…
La cohesió léxica en seqüències narratives.
2008
Aquesta tesi doctoral s'ocupa de les operacions discursivocognitivesd'establiment de referents i de represa lèxica de la referència en textos escritsd'estudiants de secundària.Partim d'un corpus doble constituït per seqüències narratives produïdes, d'unabanda, per alumnes de quart curs d'E.S.O (aprenents) i, d'altra banda, per periodistescinematogràfics (experts), que ens proporcionen el corpus de control i, doncs, la base decomparació de les produccions dels aprenents.En primer lloc, hem analitzat els diversos tipus d'estructures nominals ipredicatives que vehiculen la introducció dels referents discursius. En segon lloc, enshem ocupat de la represa lèxica dels referents mitjançant la repe…
Conditioned place preference: an animal model of motivational properties of drugs
2016
En el presente trabajo mostramos la técnica del condicionamiento de preferencia de lugar (CPL) como un modelo útil en el estudio de las propiedades motivacionales de las drogas. Se presentan los antecedentes de la técnica y se discuten algunas cuestiones metodológicas que es necesario considerar para diseñar una investigación empleando el modelo de CPL, como los diferentes tipos de aparatos disponibles, las diferentes fases del protocolo y sus posibles variaciones, el tipo de diseño (sesgado vs. no sesgado) o la necesidad de considerar los efectos del tiempo. Posteriormente se discuten algunas cuestiones a tener en cuenta a la hora de interpretar los datos obtenidos, como qué es lo que apre…
Condicionamiento de preferencia de lugar: un modelo animal para evaluar las propiedades motivacionales de las drogas (Conditioned place preference: a…
2016
This article investigated the Conditioned Place Preference (CPP) technique as a useful model for studying the motivational properties of drugs of abuse. The background of the technique is presented. Methodological issues that need to be considered when designing a study using CPP are discussed. These issues include the different types of apparatus available, the different phases of the protocol and its possible variations, the type of design (biased vs unbiased), and the need to consider time effects. We discuss data interpretation issues, such what the animal learns, the presentation of the dependent variable, the influence of novelty, state-dependent learning, latent inhibition, the motor…

EASARCICAPLivre dispo. dans :hal-00832739, version 1; Publish or Perish. This old adage illustrates the importance of scientific communication; essential to research, it also represents a strategic sector for each country’s competitiveness. An often-neglected topic, scientific communication is of vital importance, with new information technologies accelerating and profoundly changing how knowledge is disseminated. The necessity of optimally disseminating experts’ findings has also become crucial to researchers, institutes and universities alike, which has prompted the recent advent of Impact Factors for the evaluation and financing of research, the goal being for scientific knowledge to be …
