Prospective elementary teachers’ perceptions of the processes of modeling: A case study
2012
In this paper we discuss a study on the approaches to modeling of students of the 4-year elementary school teacher program at the University of Palermo, Italy. The answers to a specially designed questionnaire are analyzed on the basis of an a priori analysis made using a general scheme of reference on the epistemology of mathematics and physics. The study is performed by using quantitative data analysis methods, i.e. factorial analysis of the correspondences and implicative analysis. A qualitative analysis of key words and terms used by students during interviews is also used to examine some aspects that emerged from the quantitative analysis. The students have been classified on the basis…
Adaptación al castellano y estructura factorial del Denison Organizational Culture Survey
2009
Resumen tomado de la publicación En este estudio se presenta la adaptación al castellano del Denison Organizational Culture Survey, una encuesta diseñada para la evaluación de la cultura organizativa. Está compuesta por 60 ítems agrupados en 12 subescalas que identifican a su vez 4 dimensiones culturales, de aceptada influencia en la efectividad organizacional. La muestra consta de 488 personas y se ha utilizado análisis factorial confirmatorio. Los resultados obtenidos señalan unas propiedades psicométricas adecuadas, por lo que cabe concluir que la adaptación española replica casi en su totalidad la estructura planteada en la versión original. Asturias Colegio Oficial de Psicólogos de Ast…
Validity and reliability of a pictorial scale of physical self-concept in spanish children. [Validez y fiabilidad de la escala pictográfica de autoco…
2019
The pictorial scale of Physical Self-Concept in Children (P-PSC-C) is a relatively new instrument for investigating physical self-concept in childhood. The current study aims to examine the validity and reliability of the Spanish version of the P-PSC-C, and also to analyse the validity according to the children’s age. A sample of 365 primary school age (M = 9.21, SD = 1.92) students participated; divided in two groups, those aged 9 or younger and those 10-11 years old. Surveys were used to assess perceived physical concept individually. Confirmatory factor analysis (CFA) with diagonally weighted least square estimator specifically designed for ordinal data and a scaled test statistic was co…
Llengües, jóvens i universitat: actituds lingüístiques a València ciutat i l’àrea metropolitana
2020
Aquest article analitza les actituds dels jóvens valencians d’entre els dinou i els trenta-quatre anys respecte a les llengües oficials — valencià i castellà— segons si han realitzat o no estudis universitaris. La investigació se centra en les modalitats lingüístiques castellà estàndard (CS), valencià estàndard (VS), castellà no estàndard (CNS) i valencià no estàndard (VNS), i interpreta les dades d’acord amb el grau d’identificació i ús que els jóvens han assignat a les interaccions comunicatives, la consideració ideològica dels parlants d’una o altra llengua, així com la identificació de trets personals. Entre les conclusions, se destaca la valoració generalitzada de CS com a modalitat mi…
Evaluating the Dimensionality of the Sociocultural Adaptation Scale in a Sample of International Students Sojourning in Los Angeles: Which Difference…
2022
The Sociocultural Adaptation Scale (SCAS) measures the degree of sociocultural competence in new cultural settings, and, despite its popularity, research aiming at evaluating its dimensionality is lacking and has incongruent results. Moreover, the dimensionality of the scale has been mainly tested on different samples adjusted to Eastern culture. We administered the SCAS to 266 international students sojourning in Los Angeles to test which underlying dimensionality emerges if the measure is used to assess sociocultural adaptation to Western culture, also verifying its measurement invariance across sex. Findings from EFA showed a three-factor solution: Diversity Approach, Social Functioning,…
Emotional expression in music: contribution, linearity, and additivity of primary musical cues
2013
The aim of this study is to manipulate musical cues systematically to determine the aspects of music that contribute to emotional expression, and whether these cues operate in additive or interactive fashion, and whether the cue levels can be characterized as linear or non-linear. An optimized factorial design was used with six primary musical cues (mode, tempo, dynamics, articulation, timbre, and register) across four different music examples. Listeners rated 200 musical examples according to four perceived emotional characters (happy, sad, peaceful, and scary). The results exhibited robust effects for all cues and the ranked importance of these was established by multiple regression. The …
Importance of considering interoceptive abilities in alexithymia assessment
2019
Background Recent studies have shown that people with high alexithymia scores have decreased interoceptive abilities, which can be associated with psychological and physical disorders. Early assessments of the alexithymia trait included the evaluation of these abilities through the dimension measuring the difficulty in identifying and distinguishing between feelings and bodily sensations (the 26-item Toronto Alexithymia Scale; TAS-26). The revised version of the TAS, the TAS-20, contains a three-factor solution that does not involve a dimension assessing interoceptive abilities. However, the three items allowing the evaluation of these abilities are still present in the TAS-20. In this con…
Data from: Food provisioning alters infection dynamics in populations of a wild rodent
2015
While pathogens are often assumed to limit the growth of wildlife populations, experimental evidence for their effects is rare. A lack of food resources has been suggested to enhance the negative effects of pathogen infection on host populations, but this theory has received little investigation. We conducted a replicated two-factor enclosure experiment, with introduction of the bacterium Bordetella bronchiseptica and food supplementation, to evaluate the individual and interactive effects of pathogen infection and food availability on vole populations during a boreal winter. We show that prior to bacteria introduction, vole populations were limited by food availability. Bordetella bronchis…
