Constant sign and nodal solutions for parametric anisotropic $(p, 2)$-equations

2021

We consider an anisotropic ▫$(p, 2)$▫-equation, with a parametric and superlinear reaction term.Weshow that for all small values of the parameter the problem has at least five nontrivial smooth solutions, four with constant sign and the fifth nodal (sign-changing). The proofs use tools from critical point theory, truncation and comparison techniques, and critical groups. Spletna objava: 9. 9. 2021. Abstract. Bibliografija: str. 1076.

Pedagogical practices predicting perceived learning of social skills among university students

2022

The aim of this study was to examine what kinds of pedagogical practices predict perceived learning of university students’ social skills in classes where these skills are not set as learning outcomes. Data were collected from students of various disciplines by means of a questionnaire and then analysed using regression analysis. Students’ learning of social skills was explained by pedagogical factors related to 1) the modes of teaching and learning, 2) the features of the constructivist learning environment, 3) the features of the integrative pedagogy, and 4) the circumstances pertaining to the atmosphere of the learning environments involved in their studies. Factors belonging to three of…

Automatic evaluation of information provider reliability and expertise

2013

Published version of an article in the journal: World Wide Web. Also available from the publisher at: http://dx.doi.org/10.1007/s11280-013-0249-x Q&A social media have gained a lot of attention during the recent years. People rely on these sites to obtain information due to a number of advantages they offer as compared to conventional sources of knowledge (e.g., asynchronous and convenient access). However, for the same question one may find highly contradicting answers, causing an ambiguity with respect to the correct information. This can be attributed to the presence of unreliable and/or non-expert users. These two attributes (reliability and expertise) significantly affect the quality o…

Female reproductive factors are associated with objectively measured physical activity in middle-aged women

2017

Physical activity improves health and may delay the onset of several chronic diseases. For women in particular, the rate of these diseases accelerates at middle age; therefore it is important to identify the determinants of health-enhancing physical activity during midlife in this population. In this study, we focused on determinants that are unique to the female sex, such as childbearing and menopause. The main objective was to characterize the level of physical activity and differences between active and inactive middle-aged Finnish women. In addition, we examined the association of physical activity with female reproductive factors at midlife. The study population consisted of 647 women …

¿Por qué los estudiantes de la Universidad Pedagógica ISFODOSU escogen la carrera de Educación?

2020

As part of research aimed at establishing the profiles of students of new entry at ISFODOSU, we include vocational variables to determine the most important motivations for the choice of career of the participants, as well as for the election of this university and opinion on its technological resources. The sample (No. 744) was chosen at random, proportionally among the Enclosures, Careers and Sex strata. First, we validate the FIT-Choice scale with two confirmatory factorial analyses. The 12 motivational factors showed a good level of fit (RMSEA .062; CFI .92 and TLI .901, as well as the 6 perceptual factors (RMSEA .062; CFI .944 and TLI .924). The reliability of the motivational factors …

Referee efficacy in the context of Norwegian soccer referees – A meaningful construct?

2018

Abstract Objectives The purpose of this study was two-fold. Firstly, to examine the measurement/factorial validity and invariance of the Referee Self-Efficacy Scale (REFS) among Norwegian soccer referees. Secondly, extending scale validation, we also tested a structural model in which a second-order version of the REFS was modelled to mediate a set of theoretically informed antecedents and outcomes. Design Cross-sectional. Method One hundred and eleven Norwegian elite referees and 81 non-elite referees completed an electronic questionnaire measuring expected antecedents and outcomes of perceived self-efficacy in the role as referees. Results Analyses provided support for the first – and sec…

Spanish Validation of the Flourishing Scale in the General Population

2017

Well-being research and its measurement have grown in the last two decades. The objective of this study was to adapt and validate the Flourishing Scale in a sample of Spanish adults. This was a cross-sectional study using a non-probabilistic sample of 999 Spanish general adult population participants. The psychometric properties of the scale were analysed from an exploratory and confirmatory perspective. Exploratory factor analysis showed a one-factor solution explaining 42.3% of the variance; an internal consistency of .846; temporal reliability correlation of .749; convergent validity with the Satisfaction with Life Scale of .521 and criterion validity with positive and negative affect (P…

Psychometric properties and factor structure of the Satisfaction with Life Scale in an elderly Portuguese retirees students sample

2017

El objetivo principal de este estudio ha sido analizar las propie- dades psicométricas de la escala de Satisfacción con la Vida (SWLS) en una muestra de 363 estudiantes jubilados pertenecientes a varias universidades portuguesas. El 70% de los participantes eran mujeres frente a un 30% de hombres, con una media de edad de 67 años (SD = 7.59) y un rango de edad comprendido entre 48 y 90 años. Se realizó un Análisis Factorial Ex- ploratorio con R Commander y un Análisis Factorial Confirmatorio con Amos 18.0. El modelo que obtuvo un mejor ajuste estaba compuesto por un único factor. El índice de consistencia interna de la escala en su conjun- to fue de .777. En cuanto a la validez concurrente,…

Finnish diabetes‐related quality of life questionnaire for children and adolescents: Reliability and validity

2020

Aim To study the psychometric properties, reliability, and validity of the FinDiab quality of life questionnaire (FDQL), a strength‐oriented quality of life (QOL) questionnaire for children and adolescents with type 1 diabetes (T1D). Methods Participants were 215 youths with T1D (aged 10–17 years). They completed FDQL and comparison questionnaires (KINDL‐R and SDQ). Demographic and disease measures were collected from the participants’ medical records. The questionnaire’s psychometric properties were investigated. Construct validity was studied through principal component analysis using Promax rotation, reliability with alphas, and criterion and convergent validity with correlations between…
