Involvement in sedentary activities and academic performance in adolescents: differences according to sociodemographic variables /Implicación en acti…
2016
AbstractThis study provides a first-time analysis of the differences in the time dedicated each day to different sedentary activities (SA) (productive, technology-based recreation and social activities) and their relation with the academic performance of Spanish adolescents according to sex, school year and socioeconomic status (SES). The sample was made up of 681 participants (50.2% girls), between 12 and 18 years old, who completed self-reported questionnaires. The likelihood of obtaining lower levels of academic success increase in adolescents who spend two or more hours on social SAs and have a lower SES. With boys, this increases further if they spend four or more hours on SAs involvin…
Future Pedagogues’ Attitudes and Knowledge about Inclusive Education in Spain: an exploratory study
2015
This article analyses the attitudes and knowledge about inclusive education among students reading Pedagogy at the University of Valencia and how these are influenced by participants’ age, gender, and which academic programme or year of study they are in. This research comprises a sample of 182 students from the degree’s four year groups, which guarantee a representativeness of 95%. The principal results indicate that attitudes towards inclusive education among students reading Pedagogy are highly positive. However, they consider the training received insufficient. Regarding the participants of the study, the analysis shows that attitudes towards inclusive education are directly related to …
Gender differences in the jealousy-evoking effect of rival characteristics
2011
This study examines gender differences in the jealousy-evoking nature of rival characteristics in two Spanish-speaking countries (Argentina and Spain). A total of 388 Spanish students and 444 Argentinean students participated in the study. First, the cross-cultural validity of a Dutch scale containing 56 rival characteristics was examined. A factor analysis distinguished four dimensions (i.e., social power and dominance, physical attractiveness, physical dominance, and social-communal attributes). After the analysis, the final scale contained in total 24 items. Results showed that in Argentina and Spain combined, men experienced more jealousy than women when their rival was more physically …
Statistics Anxiety and Self-Concept of Beginning Students in the Social Sciences - A Matter of Gender and Socio-Cultural Background?
2015
Angst im Fach Statistik und statistisches Selbstkonzept von Studienanfangerinnen und -anfangern in den Sozialwissenschaften - eine Frage des Geschlechts und des sozio-kulturellen Hintergrunds? Es ist weitgehend unerforscht, ob bestimmte Studierendengruppen in den Sozialwissenschaften ihr Studium mit unterschiedlichen Einstellungen zum Fach Statistik beginnen. Im Folgenden wird untersucht, inwieweit das Geschlecht und der sozio-kulturelle Hintergrund einen Einfluss auf die Angst und das Selbstkonzept im Fach Statistik zu Studienbeginn haben. Eine Befragung von 504 Studierenden im ersten Studienjahr an zwei Universitaten und zwei Studiengangen zeigt, dass zwischen den Geschlechtern deutliche …
Factor analysis of the Spanish Burnout Inventory among public administration employees
2014
Burnout has been recognized as an important stress-related problem. Researchers have been troubled by some of the psychometric limitations of the questionnaires developed to evaluate burnout. This study was designed to assess the factor structure of the Spanish Burnout Inventory in a sample of 548 Brazilian public administration employees. This instrument comprises 20 items distributed in four dimensions: enthusiasm toward the job (5 items), psychological exhaustion (4 items), indolence (6 items), and guilt (5 items). The factor structure was examined through confirmatory factor analysis. To assess the factorial validity of the Spanish Burnout Inventory, four alternative models were tested.…
Museums, consumers, and on‐site experiences
2010
PurposeOne conclusion is widely shared by professionals in the cultural sector: consumer motivations have changed and in particular their relations with cultural products and services. This paper seeks to analyze different trends applied to museums in order to improve the understanding of this “new” cultural audience.Design/methodology/approachFor this trend marketing analysis, seven consumer orientations have been identified (without claiming they are at all exhaustive) after an extended review over the shape of contemporary consumer habits. Besides, the authors wanted to know the opinion of the cultural managers. Each consumer orientation has been evaluated by taking a sample of French pr…
EFFECTS OF CUSTOMER KNOWLEDGE MANAGEMENT AND CUSTOMER ORIENTATION ON INNOVATION CAPACITY AND MARKETING RESULTS IN SMEs: THE MEDIATING ROLE OF INNOVAT…
2018
Managing customer knowledge is a key of source for SMEs. The principal aim of this paper is to provide empirical evidence on the direct effects of two specific strategic resources: customer orientation and customer knowledge management (CKM), on innovation capacity and marketing results in SMEs. The study also examines the role of innovation orientation as a mediator between customer orientation and CKM. For this purpose, a structural model was proposed and tested through an empirical investigation with variance-based structural equation modeling (PLS) using a sample made up of 210 Spanish SMEs. The findings highlight the relevance of CKM and customer orientation as important strategic res…
Anomalous transport effects on switching currents of graphene-based Josephson junctions
2017
We explore the effect of noise on the ballistic graphene-based small Josephson junctions in the framework of the resistively and capacitively shunted model. We use the non-sinusoidal current-phase relation specific for graphene layers partially covered by superconducting electrodes. The noise induced escapes from the metastable states, when the external bias current is ramped, give the switching current distribution, i.e. the probability distribution of the passages to finite voltage from the superconducting state as a function of the bias current, that is the information more promptly available in the experiments. We consider a noise source that is a mixture of two different types of proce…
Evaluation of different InSAR multi-baseline construction methods over a dam in southern Italy
2018
Monitoring dam displacements using different techniques allows an evaluation of their structural behaviour over time. In this study, dam displacements (for the Castello dam, Agrigento, Italy) have been investigated using different Interferometric Synthetic Aperture Radar (InSAR) techniques exploiting a freely available dataset from the EU Copernicus Sentinel-1 SAR built by the European Space Agency (ESA). The dataset includes Sentinel 1A (S1A) images acquired in dual-polarization and Interferometric Wide (IW) swath using the Terrain Observation with Progressive Scans SAR (TOPSAR) mode. Three main Multi-Baseline Construction methods based on the identification of Persistent Scatterers (PS) h…
Analyzing big datasets of genomic sequences: fast and scalable collection of k-mer statistics
2019
Abstract Background Distributed approaches based on the MapReduce programming paradigm have started to be proposed in the Bioinformatics domain, due to the large amount of data produced by the next-generation sequencing techniques. However, the use of MapReduce and related Big Data technologies and frameworks (e.g., Apache Hadoop and Spark) does not necessarily produce satisfactory results, in terms of both efficiency and effectiveness. We discuss how the development of distributed and Big Data management technologies has affected the analysis of large datasets of biological sequences. Moreover, we show how the choice of different parameter configurations and the careful engineering of the …
