Measuring self-esteem in Spanish adolescents: Equivalence across gender and educational levels

2015

Rosenberg's self-esteem scale (RSES) has been applied in many areas of psychology, highlighting the interest in the study of gender differences and educational level. At the same time, there was a methodological debate on its psychometric properties. Evidence points at a scale measuring a single trait confounded by a method factor associated to negatively worded items. The aim of the study is to examine RSES differences due to gender and educational level at the factor level, while controlling for the presence of method effects, in Spanish students. A completely a priori model was separately tested in four subsamples: college men and women, and high school men and women, and an invariance r…

NUMERICAL SIMULATION OF MAGNETIC DROPLET DYNAMICS IN A ROTATING FIELD

2013

Dynamics and hysteresis of an elongated droplet under the action of a rotating magnetic field is considered for mathematical modelling. The shape of droplet is found by regularization of the ill-posed initial–boundary value problem for nonlinear partial differential equation (PDE). It is shown that two methods of the regularization – introduction of small viscous bending torques and construction of monotonous continuous functions are equivalent. Their connection with the regularization of the ill-posed reverse problems for the parabolic equation of heat conduction is remarked. Spatial discretization is carried out by the finite difference scheme (FDS). Time evolution of numerical solutions …

Mathematical modelling of an elongated magnetic droplet in a rotating magnetic field

2012

Dynamics of an elongated droplet under the action of a rotating magnetic field is considered by mathematical modelling. The actual shape of a droplet is obtained by solving the initial-boundary value problem of a nonlinear singularly perturbed partial differential equation (PDE). For the discretization in space the finite difference scheme (FDS) is applied. Time evolution of numerical solutions is obtained with MATLAB by solving a large system of ordinary differential equations (ODE).

Assessment wine aroma persistence by using an in vivo PTR-ToF-MS approach and its relationship with salivary parameters

2019

To better understand wine aroma persistence, the nasal cavity of nine volunteers was monitored by Proton Transfer Reaction-Time of Flight-Mass Spectrometry (PTR-ToF-MS) after they rinsed their mouths with three rosé wines (one control and the same wine supplemented with two tannin extracts) during four minutes. Wines were aromatised with a mixture of five target aroma compounds. Results showed that wine aroma persistence was highly compound-dependent: while esters disappeared very fast, other compounds such as linalool remained in the oral cavity for longer times after wine expectoration. A low effect of tannins (at 50 mg/L) on nasal cavity parameters was observed, with the exception for th…

The economic impact of audit failures

2022

This paper examines the economic consequences associated with an audit failure in the field of statutory auditing services, by analyzing changes in the audit firm’s market share around the time of the investigation process undertaken by the Spanish Public Oversight Board. We explore the variations in audit market share by applying the difference in differences method to a treatment group of 70 sanctioned audit firms and a matched control group of 70 non-sanctioned audit firms. The period of analysis covers the years from 1999 to 2015. Our results show that the sanctioned audit firms suffered a significant decrease in their relative number of clients. Moreover, this measure of market share d…

Scuola ed educazione nel pensiero di Jane Roland Martin

2017

The article presents Jane Roland Martin's philosophy of education in the light of the need to rethink the school according to more inclusive and gender-sentive ideals. From a pedagogical perspective, Roland Martin argues first and foremost that not one can opt for an educational ideal that claims to be free from sexual difference: this is equivalent to confirming an ideal designed for the male experience, but then proposed to both males and females as desirable goal to reach in school contexts. Roland Martin instead argues for the need to rethinking school contexts in more inclusive terms and, first of all, the ideal of "educated person". At the same time, however, this account highlights t…

RIE : revista de investigación educativa

2011

The aim of this study was to examine the impact of the type of self-concept (academic and general) and extracurricular activities on academic performance among primary school students (N = 1708), and to determine the differences of this relationship in terms of gender. We used a cluster sampling stratified into two stages and gave standardized achievement tests and ad-hoc instrument designed for academic and general self-concept and extracurricular activities. The results showed that respondents who engaged in academic extracurricular activities such as language and computer performed better in all academic subjects. Those who took music and sports also scored better in some subjects. In co…

Preadolescent EFL learners’ self-efficacy expectancies before and after completion of a grammar task: Multivariate analyses of grade level, gender, a…

2020

Learners’ task-specific self-efficacy expectancies have gained increased attention in the EFL context. Across various competence areas they have been demonstrated to substantially affect learners’ motivation, learning approach, and performance. However, certain research gaps still exist – particularly concerning younger learners’ grammar self-efficacy. Furthermore, though conceptually assumed to play an essential role in learners’ self-efficacy formation and calibration accuracy, little is empirically known about task completion effects. The same applies to the role of grade level and gender differences in lower secondary EFL classrooms. Against this background, the present study addressed …

Inter-generational learning of teachers: what and how do teachers learn from older and younger colleagues?

2018

Abstract: This paper examines how and what teachers learn from their older and younger colleagues. Data were gathered from interviews and written reports from 27 Belgian and Finnish teachers. Thematic qualitative analysis was used. The results revealed differences in what teachers learn from older and younger colleagues. Teachers reported learning innovative teaching methods and ICT skills from younger colleagues, whereas practical information, classroom management skills, self-regulation and community building were learned mainly from older colleagues. Attitudes regarding teaching and different ways of being a teacher were learned from both younger and older colleagues alike. Similarities …
