Singular levels and topological invariants of Morse Bott integrable systems on surfaces
2016
Abstract We classify up to homeomorphisms closed curves and eights of saddle points on orientable closed surfaces. This classification is applied to Morse Bott foliations and Morse Bott integrable systems allowing us to define a complete invariant. We state also a realization Theorem based in two transformations and one generator (the foliation of the sphere with two centers).
YouTube and influencers in childhood. Content analysis and educational proposals
2020
RESUMEN: La presencia de las tecnologías móviles e Internet entre los niños y jóvenes está generando nuevos marcos de comprensión, interacción y consumo de medios y contenidos. YouTube se ha convertido en una de las plataformas más utilizadas por estos, lo cual exige investigar las repercusiones ejercidas por estos influencers en los niños. En el presente trabajo se realiza una contextualización teórica sobre el nuevo entorno digital en el que Internet y las redes sociales forman parte indiscutible de la cotidianeidad, para avanzar hacia un marco metodológico y de investigación de los principales YouTubers seguidos por niños/as de Educación Primaria en España. Se ha utilizado una metodologí…
Socially desirable responding:enhancement and denial in 20 countries
2015
This article investigated the dimensionality, measurement invariance, and cross-cultural variations of social desirability. A total of 3,471 university students from 20 countries completed an adapted version of the Marlowe–Crowne scale. A two-dimensional structure was revealed in the pooled sample, distinguishing enhancement (endorsement of positive self-description) and denial (rejection of negative self-description). The factor structure was supported in most countries; medium-sized item bias was found in two denial items. In a multilevel analysis, we found that (a) there was more cross-cultural variation in denial than enhancement; (b) females tended to score higher on enhancement where…
The scale of personal conceptions of intelligence: A comparison of the Italian, Portuguese, and Romanian versions
2012
Background: The aim of this research project was to conduct studies of confirmatory factor analyses of ECPI (Scale of Personal Conceptions of Intelligence) in three different cultural contexts - Italy, Portugal and Romania. We hypothesized a bi-factor structure of the instrument constructed in Portugal by Faria (1990; 2006). Method: 617 subjects, 222 Italian, 200 Portuguese, and 195 Romanian students participated in the study, attending high school, equally distributed according to their gender and socioeconomic status. We administered the ECPI composed of 26 items, of which 15 static and 11 dynamic. Results: In the three cultural contexts the results revealed the existence of 7 items, one …
Shopping malls and neoliberal trends in Southern European cities: post-metropolitan challenges for urban planning policy
2016
Whilst shopping malls have been explored at length by critical urban studies, there has been little exploration of their role in restructuring the practice of urban and spatial planning. This article uses the shopping mall as an object of study in the light of the neoliberal trends and post-metropolisation in Southern Europe, with the aim of exploring challenges for urban governance and planning practice and with a focus on the role of the ongoing economic crisis. A threefold exploratory framework – the ‘lost-in-time scenario’, the ‘messianic mall model’ and the ‘(im)mature planning explanation’ – is used to make sense of the local versions of shopping mall development in Lisbon (Portugal) …
Measuring Collectivism and Individualism in the Third Millenium
2011
The aim in this study was to validate the Auckland Individualism-Collectivism Scale (AICS) across populations from 5 different countries and identify better ways to interpret the scores. Data were collected from New Zealand, Portugal, China, Italy, and Romania. The results indicate that the AICS is not only valid but also highly reliable (α > .70). Cluster analysis identified 4 clusters: low collectivism – high individualism; high collectivism – midlevel individualism; high collectivism – high individualism; and low collectivism – low individualism. Each group included individuals from all 4 clusters. The advantages of the AICS, the use of cluster analysis in cross-cultural measures, and…
Personal conceptions of intelligence: Cross-cultural comparisons between Portuguese and Italian students
2006
This article presents some results of an intercultural study on personal conceptions of intelligence. The sample includes 1,540 students, 811 Italians and 729 Portuguese, from both sexes and of different socioeconomic statuses, of secondary Grades 10 and 12 and of the 1st grade of several university courses in both countries. The instrument used was The Personal Conceptions of Intelligence Scale (Faria, 2003), with 26 items, translated and adapted to Portuguese and Italian. The level of education and the cultural context appear as the only variables with either principal and interaction effects on the differentiation of personal conceptions of intelligence, which are analyzed according to t…
Tears evoke the intention to offer social support: A systematic investigation of the interpersonal effects of emotional crying across 41 countries
2021
Tearful crying is a ubiquitous and likely uniquely human phenomenon. Scholars have argued that emotional tears serve an attachment function: Tears are thought to act as a social glue by evoking social support intentions. Initial experimental studies supported this proposition across several methodologies, but these were conducted almost exclusively on participants from North America and Europe, resulting in limited generalizability. This project examined the tears-social support intentions effect and possible mediating and moderating variables in a fully pre-registered study across 7007 participants (24,886 ratings) and 41 countries spanning all populated continents. Participants were prese…
Nest characteristics and associates of Dolichovespula (Hymenoptera, Vespidae) in Central Finland
2023
In social vespine wasps, the nest characteristics and associates vary intra- and interspecifically. I studied the nest characteristics and nest associates of three Dolichovespula wasp species in boreal Finland. The average number of combs and cells per nest was similar among D. media, D. saxonica and D. norwegica, and similar to Dolichovespula in the temperate zone. Most D. media and D. saxonica colonies produced both gynes and males, whereas D. norwegica produced mainly either one. The average colony lifespan of D. saxonica was a bit over two months, i.e. shorter than documented for Dolichovespula in the temperate zone. The proportion of nests parasitised by the ichneumonid wasp Sphecophag…
