Reseña teórica de la inteligencia emocional: modelos e instrumentos de medición

2013

La presente revisión teórica de la inteligencia emocional (IE) inicia con las conceptualizaciones realizadas por Galton, Binet, Stemberg Thurstone, Thordinke, Gardner, quienes en su momento histórico lograron cimentar las bases para el nacimiento de la inteligencia emocional como un constructoteórico introducido por primera vez en la literatura científica en los años noventa. Desde entonces se han desarrollado diferentes modelos de IE y al mismo tiempo se han incrementado las contribuciones investigativas.En el artículo se procede a describir en detalle los modelos deIE más representativos, como: 1) el modelo de habilidad mental (Ability Based) desarrollado por Mayer y Salovey; 2) el modelo…

Heat rectification in He II counterflow in radial geometries

2018

Abstract We consider heat rectification in radial flows of turbulent helium II, where heat flux is not described by Fourier's law, but by a more general law. This is different from previous analyses of heat rectification, based on such law. In our simplified analysis we show that the coupling between heat flux and the gradient of vortex line density plays a decisive role in such rectification. Such rectification will be low at low and high values of the heat rate, but it may exhibit a very high value at an intermediate value of the heat rate. In particular, for a given range of values for the incoming heat ow, the outgoing heat flow corresponding to the exchange of internal and external tem…

Study of phase transition in Bi3TiNbO9-BaBi2Nb2O9 ceramics

2016

Abstract The subject of the paper is lead free bismuth layer structure oxides (1-x)Bi3TiNbO9-xBaBi2Nb2O9 (x=0; 1; 2; 3 mol). The influence of Bi3TiNbO9/BaBi2Nb2O9 ratio on dielectric and structural properties was studied in a wide range of temperatures. Change in the ratio causes a decrease in the maximum value of dielectric permittivity and shifts the temperature of ε’max to low values, leading to linear decreasing of average grain size and linear increasing of ceramics density. These results indicate an augment of the packing degree and the participation of pores are significantly decreased with the increase of BaBi2Nb2O9 compound intake. Moreover, for 0.7Bi3TiNbO9-0.3BaBi2Nb2O9 ceramics …

Quality of autochthonous Sicilian plums

2015

Thirty four plum local varieties and accessions obtained from different growing area of the Sicilian island were analyzed for their qualitative and nutraceutical properties and three commercialcultivar were used as references. These properties included the fruit fresh weight (g), the pulp firmness (FFF), the total soluble solids (TSS), the titratable acidity (TA), the total anthocyanins,the phenolics content and the antioxidant activity.This preliminary study showed significantly differeces among the plums; Zuccarato giallo and Prunu Niuru presented TSS higher than the commercial cultivars (24.9 and 21.6 °Brix respectively)and interesting data obtained on the nutraceutical compounds values …

Intended or Unintended Doping? A Review of the Presence of Doping Substances in Dietary Supplements Used in Sports

2017

Introduction: The use of dietary supplements is increasing among athletes, year after year. Related to the high rates of use, unintentional doping occurs. Unintentional doping refers to positive anti-doping tests due to the use of any supplement containing unlisted substances banned by anti-doping regulations and organizations, such as the World Anti-Doping Agency (WADA). The objective of this review is to summarize the presence of unlabeled doping substances in dietary supplements that are used in sports. Methodology: A review of substances/metabolites/markers banned by WADA in ergonutritional supplements was completed using PubMed. The inclusion criteria were studies published up until Se…

"If I don’t enjoy it, how are my kids going to enjoy it?" : case study in English grammar teaching

2015

The question over how grammar should be taught has been discussed amongst s everal linguistics scholars. Different grammar teaching methods present different focus on the target language, grammar and learner’s role. All of the methods have their strengths and weaknesses and in order to know which method to pick, one must know all the strengths and weaknesses of these methods. In this case study, a teacher from Central Finland was interviewed on her grammar teaching methods and the reasons behind these methods for fifth-graders. Factors influencing her selection of methods were the grammatical topic to be taught, learners’ different learning styles, relevance of the topic and the most natura…

Yksilöllisen oppimisen mallin soveltuvuus yläkoulun 7. luokan lajintuntemuksen opetukseen

2017

Suomalaisen koulujärjestelmän uudistuksia ohjaamaan astuivat elokuussa 2016 voimaan uudet valtakunnallisen perusopetuksen opetussuunnitelmien perusteet, jotka korostavat konstruktivistista oppimiskäsitystä ja tulevaisuuden osaamiseen valmentavia tietoja ja taitoja. Biologian opetuksen tehtävänä on kartuttaa oppilaan luonnontuntemusta yhteisöllisiä ja toiminnallisia opetusmenetelmiä hyödyntäen. Sen tulee myös ohjata oppilaiden luonnontieteellisen ajattelun kehitystä vuorovaikutuksessa muiden oppilaiden kanssa. Tämän tutkimuksen tavoitteena oli tutkia matemaatikko Pekka Peuran kehittelemän yksilöllisen oppimisen mallin soveltuvuutta lajintuntemuksen opetukseen biologian oppiaineessa yläkoulun…

System identification via optimised wavelet-based neural networks

2003

Nonlinear system identification by means of wavelet-based neural networks (WBNNs) is presented. An iterative method is proposed, based on a way of combining genetic algorithms (GAs) and least-square techniques with the aim of avoiding redundancy in the representation of the function. GAs are used for optimal selection of the structure of the WBNN and the parameters of the transfer function of its neurones. Least-square techniques are used to update the weights of the net. The basic criterion of the method is the addition of a new neurone, at a generic step, to the already constructed WBNN so that no modification to the parameters of its neurones is required. Simulation experiments and compa…

Embedding Preschool Assessment Methods into Digital Learning Games to Predict Early Reading Skills

2017

The aim of this pilot study was to explore the predictive accuracy of computer-based assessment tasks (embedded within the GraphoLearn digital learning game platform) in identifying slow and normal readers. The results were compared to those obtained from the traditional paper-and-pencil tasks currently used to assess school readiness in Finland. The data were derived from a cohort of preschool-age children (mean age 6.7 years, N = 57) from a town in central Finland. A year later, at the end of first grade, participants were categorized as either slow (n = 11) or normal readers (n = 46) based on their reading scores. Logistic regression analyses indicated that computer tasks were as efficie…
