Evidence for shared environmental contributions to attention-deficit/hyperactivity traits. A twin study
2019
Background and objectives: Behavior-genetic analyses have shown that measurements of inattention and hyperactivity-impulsivity are genetically-influenced. In view of limited studies on ADHD (Attention deficit hyperactivity disorder) in Spanish samples, this study aims to explore the genetic architecture of ADHD symptoms; inattention and hyperactivity-impulsivity in a Spanish twin schoolchildren sample. Methods: Participants were 258 pairs of adolescent Spanish twins. Symptoms of ADHD, inattention and hyperactivity-impulsivity were assessed by means of a sub-scale of the Strengths and Difficulties Questionnaire. Univariate twin models, according to sex, were run to assess the heritability of…
Food pickiness in the elderly: Relationship with dependency and malnutrition
2014
Special Issue: 5th European Conference on Sensory and Consumer Research (Eurosense) 2012 "A sense of inspiration"; International audience; Among factors contributing to malnutrition in the elderly, the present study aimed at assessing the impact of food selectivity (also referred as food "pickiness") on the nutritional status of the elderly. A survey with 559 French people over 65 years old was conducted to collect data on food selectivity, dependency and nutritional status. Food selectivity was assessed by asking respondents to tick each food they dislike among a list of familiar foods. Since some foods could be ticked as disliked because elderly people experience physical difficulties in …
Game learning analytics for understanding reading skills in transparent writing system
2020
Serious games are designed to improve learning instead of providing only entertainment. Serious games analytics can be used for understanding and enhancing the quality of learning with serious games. One challenge in developing computerized support for learning is that learning of skills varies between players. Appropriate algorithms are needed for analyzing the performance of individual players. This paper presents a novel clustering-based profiling method for analyzing serious games learners. GraphoLearn, a game for training connections between speech sounds and letters, serves as the game-based learning environment. The proposed clustering method was designed to group the learners into p…
Problemi di giurisdizione nel contrasto al traffico di migranti via mare
2018
I trafficanti di esseri umani si avvalgono con sempre più insistenza di ben collaudati protocolli operativi. Questi ultimi consentono loro di sottrarsi alla giurisdizione penale italiana che non si radica qualora – in ossequio ai criteri di cui all’art. 6 c.p.ed in conformità alla Convenzione sull’Alto Mare– l’azione illecita avvenga in acque internazionali.Così, premesse alcune linee concettuali sui limiti spaziali alla efficacia della legge penale, l’indagine si sofferma sulla soluzione ermeneutica offerta dallaCassazione che, apparentemente in modo sbrigativo e per esigenze di effettività della risposta punitiva, ha fatto ricorso alla controversa figura dell’autore mediato per sanzionare condott…
Les dispositifs de prise en charge de la difficulté scolaire à l’école élémentaire : étude de leur fonctionnement et de leurs effets sur la réussite …
2018
With the Jules Ferry laws ensuring free and compulsory schooling, equal chances of succeeding were expected in a meritocratic established school system. Reality proved otherwise: attending school still does not allow all schoolchildren to progress in the same way, as some of them encounter difficulties from the beginning. The struggle against academic failure cannot stop a considerable amount of pupils from finishing school without satisfactorily mastering the basic elements of the programmes. Moreover, recent research works have seemed to prove programmes providing assistance for underachievers to be ineffective.This thesis offers a comparative evaluation of such support systems in element…
Dyscalculia: Clinical manifestations, evaluation and diagnosis. Current Perspectives of educational intervention
2019
Learning difficulties and learning disorders are very frequent in schools nowadays, and they have been increasing in the field of mathematics. Such difficulties tend to be associated with other disorders such as dyslexia or Attention Deficit Hyperactivity Disorder (ADHD). The present article aims at deepening our understanding, definition and detection of dyscalculia, along with reviewing current educational treatments. Since 1990, concerns about learning difficulties in the classroom have been made explicit in policies such as the Spanish Law on the General Ordering of the Education System (LOGSE). Likewise, the indicators, symptoms, and prevalence of dyscalculia have been gathered since t…
Problemas históricos y dificultades de los estudiantes en la conceptualización de sustancia compuesto químico
2008
Este trabajo ofrece un análisis histórico sobre los problemas que tuvo que resolver la ciencia hasta llegar a la construcción de los conceptos macroscópicos de sustancia y compuesto químico en el contexto de la teoría daltoniana. Por otra parte, en él se muestran algunas de las dificultades de comprensión que estos conceptos ofrecen a los estudiantes. Para determinarlas, se realiza un estudio transversal con alumnos de 15 a 18 años, lo que permite evaluar el significado que otorgan a la idea de sustancia, al tiempo que se constata la necesidad de su comprensión para poder entender los cambios químicos. Por último, se plantea la existencia de ciertas semejanzas entre las ideas sobre la compo…
Predictability of oppositional defiant disorder and symptom dimensions in children and adolescents with ADHD combined type.
2010
BackgroundOppositional defiant disorder (ODD) is frequently co-occurring with attention deficit hyperactivity disorder (ADHD) in children and adolescents. Because ODD is a precursor of later conduct disorder (CD) and affective disorders, early diagnostic identification is warranted. Furthermore, the predictability of three recently confirmed ODD dimensions (ODD-irritable, ODD-headstrong and ODD-hurtful) may assist clinical decision making.MethodReceiver-operating characteristic (ROC) analysis was used in order to test the diagnostic accuracy of the Conners' Parent Rating Scale revised (CPRS-R) and the parent version of the Strength and Difficulties Questionnaire (PSDQ) in the prediction of …
Adding Clinical Validity to the Statistical Power of Large-Scale Epidemiological Surveys on Internet Addiction in Adolescence
2015
OBJECTIVE Research has indicated that internet addiction is associated with psychosocial maladjustment in adolescence. Many epidemiologic surveys are lacking representativeness, and knowledge on disorder-specific risk factors is scarce. One weakness of epidemiologic studies often regards their lack of generalizability to clinical reality. The aim of this study was to provide a detailed description of internet addiction among adolescents, focusing on its prevalence in a population-based context, psychopathological correlates, and predisposing factors. METHODS The main analyses were based on 2 large representative samples of German adolescents (N = 9,293; 12-19 years) collected in 2012, and t…
The first case of myoclonic epilepsy in a child with a de novo 22q11.2 microduplication
2011
Chromosome 22, particularly the q11.2 sub-band, has long been recognized as responsible for multiple congenital anomaly disorders. In particular, its susceptibility to subtle microdeletions or, more rarely, microduplications has been attributed to the presence of several low-copy repeats spanning the region as mediators of nonallelic homologous recombination that result in 22q11.2 rearrangements. While recent data suggest that the frequency of 22q11.2 microduplications could be approximately half of all deletions, now only 50 unrelated cases have been reported thus far. However, it is reasonable to suppose that microduplications of 22q11.2 may be largely undetected as a result of a less-dis…
