Comisión de Test: veinticinco años velando por la calidad de los test
2022
[ES]El objetivo del presente trabajo es mostrar las actividades y proyectos llevados a cabo por la Comisión de Test del Consejo General de Psicología de España para mejorar la calidad y el uso de los test. Se repasan los proyectos más relevantes de la comisión durante sus veinticinco años de existencia, describiendo los trabajos llevados a cabo para a) conocer las opiniones y actitudes de los psicólogos hacia los test, b) evaluar la calidad de los test editados en España, y c) desarrollar estándares, directrices y códigos éticos y deontológicos que mejoren la práctica de los test. También se resaltan otras actividades de la comisión de carácter formativo, así como sus relaciones con otras o…
Revisión del modelo para evaluar la calidad de los tests utilizados en España
2016
Para usar adecuadamente los tests, es necesario que los profesionales cuenten con información rigurosa de su calidad. Es por ello que, desde hace unos años, se viene aplicando el modelo español de evaluación de la calidad de los tests (Prieto y Muñiz, 2000). El objetivo de este trabajo es actualizar y revisar dicho modelo, con el fin de incorporar las recomendaciones hechas en sus aplicaciones, y para incorporar los avances psicométricos y tecnológicos que se han producido durante los últimos años. El modelo original fue revisado en varias fases, y la revisión originalmente propuesta fue revisada por un conjunto de expertos, lo que dio lugar a la versión final que se describe en este trabaj…
Salivary Microbiota Composition in Patients with Oral Squamous Cell Carcinoma: A Systematic Review.
2022
Background: Oral squamous cell carcinoma (OSCC) is one of the most prevalent cancers worldwide. Despite recent advances in diagnosis and treatment, in recent years, an increase in the incidence of OSCC has been registered, and the mortality rate is still high. This systematic review aims to identify a potential association between the composition of salivary microbiota and OSCC. Materials and Methods: The protocol for this study was designed following the PRISMA guidelines. Records were identified using different search engines (e.g., Medline/PubMed). Observational studies, in human subjects with histological diagnosis of OSCC, concerning the analysis of salivary microbiota, were selected. …
Prognostic significance of spatial and density analysis of T lymphocytes in colorectal cancer.
2022
Abstract Background Although high T cell density is a strong favourable prognostic factor in colorectal cancer, the significance of the spatial distribution of T cells is incompletely understood. We aimed to evaluate the prognostic significance of tumour cell-T cell co-localisation and T cell densities. Methods We analysed CD3 and CD8 immunohistochemistry in a study cohort of 983 colorectal cancer patients and a validation cohort (N = 246). Individual immune and tumour cells were identified to calculate T cell densities (to derive T cell density score) and G-cross function values, estimating the likelihood of tumour cells being co-located with T cells within 20 µm radius (to derive T cell p…

Aggiunte al catalogo di Bonaventura Caruso, sacerdote e orafo messinese della seconda metà del ‘700
2011
Il nome di Bonaventura Caruso, sacerdote e orafo messinese, compare per la prima volta intorno agli anni '70 del XVIII secolo. L'autore, attraverso lo studio delle fonti e grazie a un'accurata analisi stilistica, propone l'identificazione e l'attribuzione a Caruso di un gruppo di opere di argenteria sacra prodotta a Messina oggi nei tesori delle Chiese Madri di Geraci Siculo e Mistretta, tutte caratterizzate dalla presenza di forme e motivi decorativi rococò, ma già tendenti al neoclassicismo. The name of Bonaventura Caruso, a priest and goldsmith from Messina, first appears around the 1870s. The author, through the study of sources and thanks to careful stylistic analysis, proposes the ide…

Characterization of Endocytic Components of Liver Nonparenchymal Cells
1993
Liver is made up of at least five important cell types: hepatocytes, endothelial cells, Kupffer cells, pit cells, and fat-storing cells. These cells have been broadly classified into two groups: parenchymal cells, or the hepatocytes which comprise almost 65% of the liver cells (Miyai, 1979), and nonparenchymal cells, to which all the other cell types belong.
Individual behavior support in positive behavior support schools in Finland
2023
One objective in Finnish basic education is for pupils with disabilities or behavioral problems to be able to participate in mainstream education and ordinary classrooms. Positive behavior support (PBS) is an approach that offers multi-tiered behavior support for pupils. In addition to providing support at a universal level, educators need to have the necessary skills to provide more intensive individual support for pupils who need it. Check-in/Check-out (CICO) is a research-based individual support system that is widely used in PBS schools. The Finnish application of CICO includes an individual behavior assessment process for pupils with persistent challenging behaviors. In this article, w…
Chaotic dynamics in an unstirred ferroin catalyzed Belousov–Zhabotinsky reaction
2009
Abstract The Belousov–Zhabotinsky (BZ) reaction is the best known example of far from equilibrium self-organizing chemical reaction. Among the many dynamical behaviors that this reaction can exhibit, spatio-temporal chaos attracted particular interest, both for the ferroin and cerium catalyzed systems. In recent years transient chaos was found in the cerium catalyzed BZ reaction, when conducted in batch and unstirred reactors. It was established that the chaotic oscillations, originated by the coupling among chemical kinetics and transport phenomena, appeared and disappeared following a Ruelle–Takens–Newhouse scenario. In this Letter, we show results about the ferroin catalyzed system condu…
