Una aproximación a las concepciones de estudiantes preuniversitarios y universitarios sobre pilas galvánicas
2014
En el presente trabajo se han investigado las concepciones alternativas sobre pilas galvánicas y las interpretaciones de los procesos que tienen lugar en una pila voltaica simple. Han participado en él 55 estudiantes del 2º de Bachillerato español (curso previo al ingreso en la universidad) y 43 estudiantes de primer año del Grado de Química. El análisis comparativo de los resultados de la administración de un test y de una pregunta abierta revela que: a) Tanto los estudiantes de 2º de bachillerato como los de 1º de Grado sostienen concepciones erróneas sobre pilas galvánicas; b) No hay diferencias significativas en las concepciones e interpretaciones entre ambos grupos de estudiantes, y c)…
Evaluación por rúbricas de la Composición Escrita en 2º ciclo de Educación Primaria
2015
Evaluación por rúbricas de la Composición Escrita en 2º ciclo de Educación Primaria. Resumen El objetivo de este estudio de tesis doctoral es elaborar y validar un sistema de rúbricas como instrumento de evaluación e información de los procesos docentes, permitiendo la medición de aprendizajes complejos; en concreto, la habilidad para componer textos escritos, cuando aún no está consolidada esta subcompetencia; es decir, durante su proceso de adquisición. El nivel educativo seleccionado para la obtención de las muestras de producción escrita es 2º Ciclo de Educación Primaria, con alumnos entre los 8 y 10 años. Y la cuestión es ¿evalúa la rúbrica construida lo que intenta medir? Para ello, s…
Managing Municipal Solid Waste: Energetic and Environmetal Comparison among different options
2001
Goal. This research aims to assess the environmental effects of integrated strategies in a municipal waste management system. In particular, analysis is focused on a waste stream in Palermo, where landfill involves the prompt disposal of the most waste after collection. The current local management system is compared with two integrated waste management alternatives. Both the options comply with Italian regulations, but each one predicts adopting the available technologies in different ways. Methods and objectives. Energetic and environmental balances are carried out in each management system referring to local waste composition in order to quantify energy consumption, the recovery of mater…
Efficient checking of coherence and propagation of imprecise probability assessments
2000
We consider the computational difficulties in the checking of coherence and propagation of imprecise probability assessments. We examine the linear structure of the random gain in betting criterion and we propose a general methodology which exploits suitable subsets of the set of values of the random gain. In this way the checking of coherence and propagation amount to examining linear systems with a reduced number of unknowns. We also illustrate an example.
Psychiatrists' Attitudes Toward Disruptive New Technologies: Mixed-Methods Study
2018
Background Recent discoveries in the fields of machine learning (ML), Ecological Momentary Assessment (EMA), computerized adaptive testing (CAT), digital phenotype, imaging, and biomarkers have brought about a new paradigm shift in medicine. Objective The aim of this study was to explore psychiatrists’ perspectives on this paradigm through the prism of new clinical decision support systems (CDSSs). Our primary objective was to assess the acceptability of these new technologies. Our secondary objective was to characterize the factors affecting their acceptability. Methods A sample of psychiatrists was recruited through a mailing list. Respondents completed a Web-based survey. A quantitative…
Development of Computerized Adaptive Testing for Emotion Regulation
2020
Emotion regulation (ER) plays a vital role in individuals’ well-being and successful functioning. In this study, we attempted to develop a computerized adaptive testing (CAT) to efficiently evaluate ER, namely the CAT-ER. The initial CAT-ER item bank comprised 154 items from six commonly used ER scales, which were completed by 887 participants recruited in China. We conducted unidimensionality testing, item response theory (IRT) model comparison and selection, and IRT item analysis including local independence, item fit, differential item functioning, and item discrimination. Sixty-three items with good psychometric properties were retained in the final CAT-ER. Then, two CAT simulation stud…
P300 amplitudes in the Concealed Information Test are less affected by depth of processing than electrodermal responses
2012
The Concealed Information Test (CIT) has been used in the laboratory as well as in field applications to detect concealed crime related memories. The presentation of crime relevant details to guilty suspects has been shown to elicit enhanced N200 and P300 amplitudes of the event-related brain potentials (ERPs) as well as greater skin conductance responses (SCRs) as compared to neutral test items. These electrophysiological and electrodermal responses were found to incrementally contribute to the validity of the test, thereby suggesting that these response systems are sensitive to different psychological processes. In the current study, we tested whether depth of processing differentially af…
From imprecise probability assessments to conditional probabilities with quasi additive classes of conditioning events
2012
In this paper, starting from a generalized coherent (i.e. avoiding uniform loss) intervalvalued probability assessment on a finite family of conditional events, we construct conditional probabilities with quasi additive classes of conditioning events which are consistent with the given initial assessment. Quasi additivity assures coherence for the obtained conditional probabilities. In order to reach our goal we define a finite sequence of conditional probabilities by exploiting some theoretical results on g-coherence. In particular, we use solutions of a finite sequence of linear systems.
Probabilistic Logic under Coherence: Complexity and Algorithms
2005
In previous work [V. Biazzo, A. Gilio, T. Lukasiewicz and G. Sanfilippo, Probabilistic logic under coherence, model-theoretic probabilistic logic, and default reasoning in System P, Journal of Applied Non-Classical Logics 12(2) (2002) 189---213.], we have explored the relationship between probabilistic reasoning under coherence and model-theoretic probabilistic reasoning. In particular, we have shown that the notions of g-coherence and of g-coherent entailment in probabilistic reasoning under coherence can be expressed by combining notions in model-theoretic probabilistic reasoning with concepts from default reasoning. In this paper, we continue this line of research. Based on the above sem…
Validation and Measurement Invariance of the Scale of Positive and Negative Experience (SPANE) in a Spanish General Sample
2020
Este artículo se encuentra disponible en la siguiente URL: https://www.mdpi.com/1660-4601/17/22/8359 Este artículo pertenece a la sección "Health behavior, chronic disease and health promotion". Well-being has been measured based on di erent perspectives in positive psychology. However, it is necessary to measure a ects and emotions correctly and to explore the independence of positive and negative a ect. This cross-sectional study adapts and validates the Scale of Positive and Negative Experience (SPANE) with a non-probabilistic sample of 821 Spanish adults. A confirmatory factor analysis confirmed two related factors with two correlated errors. The average variance extracted was 0.502 for…
