Homogeneous actions on the random graph
2018
We show that any free product of two countable groups, one of them being infinite, admits a faithful and homogeneous action on the Random Graph. We also show that a large class of HNN extensions or free products, amalgamated over a finite group, admit such an action and we extend our results to groups acting on trees. Finally, we show the ubiquity of finitely generated free dense subgroups of the automorphism group of the Random Graph whose action on it have all orbits infinite.
Does the Relation between Rapid Automatized Naming and Reading Depend on Age or on Reading Level? A Behavioral and ERP Study
2018
Reading predictors evolve through age: phonological awareness is the best predictor of reading abilities at the beginning of reading acquisition while Rapid Automatized Naming (RAN) becomes the best reading predictor in more experienced readers (around 9–10 years old). Those developmental changes in the relationship between RAN and reading have so far been explained in term of participants' age. However, it should be noted that in the previous experiments age always co-vary with participants reading level. It is thus not clear whether RAN-reading relationship is developmental in nature or related to the reading system itself. This study investigates whether the behavioral changes in the rel…
Dynamics and reactivity in Thermus aquaticus N6-adenine methyltransferase.
2014
M.TaqI is a DNA methyltransferase from Thermus aquaticus that catalyzes the transfer of a methyl group from S-adenosyl-l-methionine to the N6 position of an adenine, a process described only in prokaryotes. We have used full atomistic classical molecular dynamics simulations to explore the protein–SAM–DNA ternary complex where the target adenine is flipped out into the active site. Key protein–DNA interactions established by the target adenine in the active site are described in detail. The relaxed structure was used for a combined quantum mechanics/molecular mechanics exploration of the reaction mechanism using the string method. According to our free energy calculations the reaction takes…
The influence of treatment programmes on the recidivism of juvenile and adult offenders: An european meta-analytic review
1999
Abstract Meta-analyses have examined the effectiveness of different treatment techniques on delin-quent and criminal behaviour in America and Europe. In one of the last meta-analyses, that integrated the results of programmes applied in European countries (Redondo, Garrido, and Sanchez-Meca, 1997), the global effect size obtained for all treatment and effectiveness measures (Psychological factors, education, etc.) was d = 0.3039 (r = 0.15). In general, it muld be interpreted that treatment groups surpassed controls by 15%, On this work, the results of a meta-analysis to determine which treatments are more effective in reducing on recidivism rates are presented. A total of 32 European studie…
Survival of 86,690 patients with thyroid cancer: A population-based study in 29 European countries from EUROCARE-5
2017
Background: Incidence rates of thyroid cancer (TC) increased in several countries during the last 30 years, while mortality rates remained unchanged, raising important questions for treatment and follow-up of TC patients. This study updates population-based estimates of relative survival (RS) after TC diagnosis in Europe by sex, country, age, period and histology.Methods: Data from 87 cancer registries in 29 countries were extracted from the EUROCARE-5 dataset. One-and 5-year RS were estimated using the cohort approach for 86,690 adult TC patients diagnosed in 2000-2007 and followed-up to 12/31/2008. RS trends in 1999-2007 and 10-year RS in 2005-2007 were estimated using the period approach…
How much space for communication is there for a low achieving student in a heterogeneous group ?
2015
International audience; This paper reports on a case study aiming to deepen our understanding of low achieving students' learning of algebra, in particular when they work with pattern problems. We observed one low achieving student, May, who participated and worked in three different heterogeneous settings. Data were analysed from a multimod-al perspective on key and regulating activities in the groups. The analysis revealed that May's contribution varied, depending on the composition of the groups, and that her contributions were influenced by regulating activities by peers and access to physical artefacts. The findings show that a low achieving student is able to generalise beyond her ari…
Perspectives of health personnel on how to preserve and promote the patients' dignity in a rehabilitation context.
2013
Aims and objectives To explore how healthcare personnel comprehend the term dignity and what they do to attend to, preserve and promote the dignity of patients in the rehabilitation context. Background Literature reveals that knowledge exists concerning the nature of dignity. Literature is scant on how health personnel think the reasons may be when patients do not maintain their dignity or how caregivers might improve and strengthen their concern in preserving and promoting the patients' dignity in a rehabilitation context. Design The study was explorative and descriptive, with content analysis of gathered empirical data. Methods Qualitative focus group interviews with representatives from …
Introduzione alle relazioni finali dei gruppi
2016
Sono introdotte e commentate le relazioni finali dei gruppi di studio che si sono svolti durante la Summer School organizzata dalla Siped a Enna nel luglio del 2015. I diversi contributi sono collocati all’interno del dibattito scientifico in corso per ognuno dei temi affrontati nei lavori svolti durante la manifestazione sulle tendenze della ricerca pedagogica in Italia. The final reports of the study groups that worked during the Summer School organized by SIPED in Enna in July 2015 are here introduced and discussed. The various contributions are placed within the current scientific debate for each one of the themes dealing with during the demonstration on pedagogical research trends in I…
Dimensionality and factorial invariance of religiosity among Christians and the religiously unaffiliated: A cross-cultural analysis based on the Inte…
2019
We present a study of the dimensionality and factorial invariance of religiosity for 26 countries with a Christian heritage, based on the 1998 and 2008 rounds of the International Social Survey Programme (ISSP) Religion survey, using both exploratory and multi-group confirmatory factor analyses. The results of the exploratory factor analysis showed that three factors, common to Christian and religiously unaffiliated respondents, could be extracted from our initially selected items and suggested the testing of four different three-factor models using multi-group confirmatory factor analysis. For the model with the best fit and measurement invariance properties, we labeled the three resulting…
