Projecte d'investigació-acció: Violència escolar i integració social
2006
En aquest treball es presenta el Projecte d'Investigació-Acció realitzat pel grup Lisis de la Universitat de València. Des del model ecològic, l'interès està a analitzar i prevenir la conducta violenta entre iguals a l'escola. Per a això s'ha aplicat en una mostra de 1319 adolescents d'edats compreses entre els 11 i els 16 anys una bateria d'instruments. En aquest article s'exposa, a tall d'exemple, un dels models d'equacions estructurals calculats en aquesta investigació. En concret s'analitza l'efecte directe i l'indirecte del clima familiar en la conducta violenta entre iguals i en el context escolar.
‘It Goes Around the World’ : Children’s Understanding of the Internet
2019
The Internet has become an important literacy environment, even for children. Therefore, building the foundations for their critical engagement with online information should start when they first enter school. One way to start is to help children build an understanding about the complexities of the Internet environment. The present study aimed at increasing our knowledge about children’s understanding of the Internet as a technical and social environment. It also explored how children perceive the trustworthiness of online information. The participants included 30 children aged 7–9 years. The children were interviewed and the data was analysed using content analysis. We share the results f…
Grade repetition at primary school level "CP"
2005
This research on the grade retention to the CP erects a detailed inventory of the knowledge on this question which gives rise to the more of animated discussions between the researchers and the teachers, and this since a long time. By allying the historic, comparative, economical and educational approaches, she conveys principal empirical results attached to the many facets of this measure that is more than an educational done. The empirical contribution of this study is based on a longitudinal followed during two years about more than three thousand students on CP in public schools of the French department of the Côte d'Or. We highlight that the grade retention are received favourably by t…
Predicting children's mathematical performance in grade one by early numeracy
2010
Abstract This longitudinal study examined how children's early numeracy assessed in kindergarten predicts their mathematical performance in the first grade, after controlling for the effects of age, gender, and parents' education. The participants were 212 Finnish children (107 girls and 105 boys). At the time of the first assessment (kindergarten), the mean age was six years, and the second assessment was conducted one year later. The results demonstrate that the acquisition of counting and relational skills before formal schooling are predictive of the acquisition of basic arithmetical skills and overall mathematical performance in grade one, above and beyond the effects of demographic fa…
Phenotypic analysis of individuals with Costello syndrome due to HRAS p.G13C.
2011
Costello syndrome is characterized by severe failure-to-thrive, short stature, cardiac abnormalities (heart defects, tachyarrhythmia, and hypertrophic cardiomyopathy (HCM)), distinctive facial features, a predisposition to papillomata and malignant tumors, postnatal cerebellar overgrowth resulting in Chiari 1 malformation, and cognitive disabilities. De novo germline mutations in the proto-oncogene HRAS cause Costello syndrome. Most mutations affect the glycine residues in position 12 or 13, and more than 80% of patients share p.G12S. To test the hypothesis that subtle genotype-phenotype differences exist, we report the first cohort comparison between 12 Costello syndrome individuals with p…
Analysis of relapse after transplantation in acute leukemia: A comparative on second allogeneic hematopoietic cell transplantation and donor lymphocy…
2018
Relapse of acute leukemia (AL) after allogeneic hematopoietic cell transplantation (Allo-HCT) entails a dismal prognosis. In this scenario, donor lymphocyte infusions (DLIs) and second Allo-HCT are two major approaches. We compared outcomes of AL patients treated for relapse with DLI or second Allo-HCT after receiving debulking therapy. In total, 46 patients were included in the study; 30 (65%) had acute myeloid leukemia and 16 (35%) had acute lymphoblastic leukemia. The median age was 38 years (range 4-66). Twenty-seven patients received a second Allo-HCT and 19 patients received DLI. The median follow-up of the cohort was 273 days (range 9-7013). Overall survival (OS), disease-free surviv…
Comparative column chromatographic estimations of phenylalanine in plasma, whole blood, native and paper-dried capillary blood of healthy children an…
1984
The concentration of phenylalanine in plasma, whole venous and capillary blood, and paper-dried blood of 75 probands (25 healthy adults, 27 healthy children, and 23 patients with hyperphenylalaninaemia) were measured by use of a sensitive short column chromatography method. The comparison of the values in each group of probands by several statistic methods showed an excellent correlation of the phenylalanine concentration in paper-dried whole blood to those measured in venous plasma. Evaluation of the analytical method revealed a high sensitivity and accuracy by use of a sample volume of 50 microliter. We would therefore suggest that the estimation of phenylalanine for the diagnosis and the…
Four unrelated patients with lubs X-linked mental retardation syndrome and different Xq28 duplications
2010
The Lubs X-linked mental retardation syndrome (MRXSL) is caused by small interstitial duplications at distal Xq28 including the MECP2 gene. Here we report on four novel male patients with MRXSL and different Xq28 duplications delineated by microarray-based chromosome analysis. All mothers were healthy carriers of the duplications. Consistent with an earlier report [Bauters et al. (2008); Genome Res 18: 847-858], the distal breakpoints of all four Xq28 duplications were located in regions containing low-copy repeats (LCRs; J, K, and L groups), which may facilitate chromosome breakage and reunion events. The proximal breakpoint regions did not contain known LCRs. Interestingly, we identified …
National level wealth inequality and socioeconomic inequality in adolescent mental wellbeing
2020
Abstract Background Previous research established a positive association between national income inequality and socioeconomic inequalities in adolescent health, but little is known about the extent to which national level inequalities in accumulated financial resources (i.e. wealth) are associated with these health inequalities. Therefore, we examined the association between national wealth inequality and income inequality and socioeconomic inequalities in adolescent mental wellbeing. Methods Data were from 17 countries participating in three successive waves (2010, 2014 and 2018) of the cross-sectional Health Behaviour in School-aged Children (HBSC) study. We combined individual-level data…
Adolescent use of social media and associations with sleep patterns across 18 European and North American countries
2023
Objective Over the past decade, concurrent with increasing social media use (SMU), there has been a shift toward poorer sleep among adolescents in many countries. The purpose of this study was to examine the cross-national associations between adolescent SMU and sleep patterns, by comparing 4 different categories of SMU (nonactive, active, intense, and problematic use). Design, setting, and participants Data were from 86,542 adolescents in 18 European and North American countries that participated in the 2017/18 Health Behaviour in School-aged study. Measurements Mixed-effects linear regression models were used to examine cross-national associations between 4 SMU categories and adolescent s…
