Applying Artificial Intelligence Methods to Detect and Classify Fish Calls from the Northern Gulf of Mexico
2021
Passive acoustic monitoring is a method that is commonly used to collect long-term data on soniferous animal presence and abundance. However, these large datasets require substantial effort for manual analysis
Validation of a Modified Version of the Psychological Capital Questionnaire (PCQ12) in Spain
2018
Background : Previous studies have found some limitations and inconsistencies in the functioning of the short Psychological Capital Questionnaire (PCQ12), suggesting the need to improve it. The objective of the current study is to validate a modified version of the PCQ12 in Spain. Method : The sample consists of 792 employees from 42 Spanish organizations. A cross-validation was carried out to test the factorial validity of the modified scale. Reliability and convergent, discriminant, and criterion validity were also tested. Results : The modified PCQ12 showed good psychometric qualities. A four-factor structure showed a better fit to the data than the original second-order structure. Conc…
La formación inicial del profesorado de Educación Secundaria: una mirada comparativa en la Unión Europea
2011
El artículo comienza exponiendo los modelos que se han utilizado en la formación del profesorado de Secundaria y sus características, para adentrarse en el modelo de formación español y analizarlo a la luz de esos paradigmas formativos. Posteriormente se describe el cambio realizado en España con la introducción del Máster de Formación del Profesorado de Secundaria, estudiando el efecto de los cambios y las dificultades habidas en su introducción. En la segunda parte se analiza la formación de los docentes europeos desde variables como el modelo formativo, los salarios, el tiempo de trabajo o la jubilación, y se establece una serie de conclusiones finales sobre la realidad y la prospectiva …
The teacher of physical education in primary textbooks
2019
El objetivo del presente estudio es analizar cómo se representa a la maestra de educación física en los libros de texto de esta área, en la etapa de Educación Primaria. Se realiza un estudio cuantitativo que muestra un número elevado de maestras con respecto al maestro de educación física, principalmente en el primer ciclo de Primaria y otro cualitativo, a través del análisis de contenido, identificando un tratamiento estereotipado en cuanto a las características físicas de la docente, al representar a una maestra eminentemente joven, de raza blanca, delgada, con ropa deportiva y sin discapacidad. Pero a la vez, aparece un tratamiento más abierto y participativo en cuanto al rol representad…
¿Qué representan las portadas de los libros de texto de Educación Física en Primaria?
2018
Resumen. Este estudio analiza la imagen del cuerpo representado en las portadas de los libros de texto de Educación Física vinculado a un tipo de actividad física, para comprobar si se ajustan a las directrices que marca la legislación actual con respecto a los materiales curriculares. El estudio es de tipo empírico, descriptivo y comparativo entre los libros de texto analizados. La muestra estuvo constituida por 12 portadas de dos editoriales, publicadas bajo la Ley Orgánica 8/2013 para la Mejora de la Calidad Educativa (LOMCE). La técnica de investigación fue el análisis de contenido a través de la herramienta SAIMEF (Sistema de Análisis de Imágenes en Educación Física). Se realizó un aná…
Intelligence in DSM-IV combined type attention-deficit/hyperactivity disorder is not predicted by either dopamine receptor/transporter genes or other…
2008
Contains fulltext : 69677.pdf (Publisher’s version ) (Closed access) A major goal of genetic studies of attention deficit hyperactivity disorder (ADHD) is to identify individual characteristics that might help segregate the disorder's inherent heterogeneity. [Mill et al. (2006); Arch Ger Psychiatry 63:462-469] recently reported a potentially important association between two dopamine-related risk polymorphisms (DRD4 variable number tandem repeat (VNTR) in exon 3 and DAT1 VNTR in the 3' UTR) and lowered IQ in ADHD. The objective of the current study was to replicate the [Mill et al. (2006); Arch Ger Psychiatry 63:462-469] findings in a clinical sample and to extend the analysis to a large ra…
Genetic heterogeneity in ADHD: DAT1 gene only affects probands without CD
2008
Contains fulltext : 70183.pdf (Publisher’s version ) (Closed access) Previous studies have found heterogeneous association between DAT1-3'-UTR-VNTR and attention deficit hyperactivity disorder (ADHD). Various proportions of conduct disorder (CD) comorbidity in their ADHD samples may partially explain the observational discrepancies. Evidence for this comes from family and twin studies which found ADHD probands with CD (ADHD + CD) are genetically different from those without CD (ADHD - CD). Genotypes of 20 DAT1 markers were analyzed in 576 trios, consisting of 141 ADHD + CD and 435 ADHD - CD. In addition to the classical TDT test, a specific genetic heterogeneity test was performed to identi…
Separation of Cognitive Impairments in Attention-Deficit/Hyperactivity Disorder Into 2 Familial Factors
2010
Contains fulltext : 89304.pdf (Publisher’s version ) (Open Access) CONTEXT: Attention-deficit/hyperactivity disorder (ADHD) is associated with widespread cognitive impairments, but it is not known whether the apparent multiple impairments share etiological roots or separate etiological pathways exist. A better understanding of the etiological pathways is important for the development of targeted interventions and for identification of suitable intermediate phenotypes for molecular genetic investigations. OBJECTIVES: To determine, by using a multivariate familial factor analysis approach, whether 1 or more familial factors underlie the slow and variable reaction times, impaired response inhi…
The impact of study design and diagnostic approach in a large multi-centre ADHD study: Part 2: Dimensional measures of psychopathology and intelligen…
2011
Contains fulltext : 97437.pdf (Publisher’s version ) (Open Access) BACKGROUND: The International Multi-centre ADHD Genetics (IMAGE) project with 11 participating centres from 7 European countries and Israel has collected a large behavioural and genetic database for present and future research. Behavioural data were collected from 1068 probands with ADHD and 1446 unselected siblings. The aim was to describe and analyse questionnaire data and IQ measures from all probands and siblings. In particular, to investigate the influence of age, gender, family status (proband vs. sibling), informant, and centres on sample homogeneity in psychopathological measures. METHODS: Conners' Questionnaires, St…
CheS-Mapper - Chemical Space Mapping and Visualization in 3D
2012
Abstract Analyzing chemical datasets is a challenging task for scientific researchers in the field of chemoinformatics. It is important, yet difficult to understand the relationship between the structure of chemical compounds, their physico-chemical properties, and biological or toxic effects. To that respect, visualization tools can help to better comprehend the underlying correlations. Our recently developed 3D molecular viewer CheS-Mapper (Chemical Space Mapper) divides large datasets into clusters of similar compounds and consequently arranges them in 3D space, such that their spatial proximity reflects their similarity. The user can indirectly determine similarity, by selecting which f…
