Psychometric Properties and Measurement Invariance by Gender of the Abbreviated Three-Item Version of the Satisfaction with Life Scale in a Colombian…
2022
(1) Background: The need to offer brief scales with items that can be answered with few response options is increasingly important in order to be able to access a broad range of the population. The three-item version of Diener’s Satisfaction with Life Scale has recently been proposed. The objective of this study is to study the psychometric properties of the three-item version of this Scale with five response options, as well as the measurement invariance by gender, in a Colombian sample; (2) Methods: A confirmatory factor model of the three items of the scale together with the Flourishing Scale has been tested, and the measurement invariance by gender of the model has been studied. The res…
Is there any scaling in the cluster distribution?
1994
We apply fractal analysis methods to investigate the scaling properties in the Abell and ACO catalogs of rich galaxy clusters. We also discuss different technical aspects of the method when applied to data sets with small number of points as the cluster catalogs. Results are compared with simulations based on the Zel'dovich approximation. We limit our analysis to scales less than 100 $\hm$. The cluster distribution show a scale invariant multifractal behavior in a limited scale range. For the Abell catalog this range is 15--60$\hm$, while for the ACO sample it extends to smaller scales. Despite this difference in the extension of the scale--range where scale--invariant clustering takes plac…
Structural invariance and stability of sense of coherence: A longitudinal analysis of two groups with different employment experiences
2005
This 5-year follow-up study investigated the structure and the factorial invariance of the 13-item sense of coherence (SOC) scale (Antonovsky, 1987a) in two employment groups (unemployment/lay-off experiences vs. continuous full-time employment) and across two measurement times. In addition, the stability of SOC between these two employment groups was compared. The postal questionnaire data was collected twice, in 1992 and in 1997. The participants were Finnish technical designers (N=352) aged between 25 and 40 years in 1992. A total of 51% of the investigated participants had been employed full-time during the 5-year follow-up period and 49% had been unemployed and/or laid off for a total …
Effects of school climate and teacher self-efficacy on job satisfaction of mostly STEM teachers: a structural multigroup invariance approach
2020
Abstract Background Identification and retention of effective teachers in STEM education play cardinal roles in teacher recruitment exercises worldwide. Studies on factors that characterize effective teachers have therefore gained popularity in recent times. Teacher self-efficacy, job satisfaction and school climate are among other factors that have attracted global attention. Thus, proper understanding of the relations between these factors is equally important. The purpose of this study is to validate and cross-validate a model of direct/indirect effects of school climate and teacher self-efficacy on job satisfaction. Results The data used for the current study are extracted from a public…
A multinational study exploring adolescent perception of school climate and mental health.
2021
School climate is a topic of increasing importance internationally. The current study investigated the established measurement invariance of an eight-factor school climate scale using a multinational sample of secondary students. School climate factor means across 14 international groups were compared and findings on the association between school climate factors and mental health were also investigated. Findings, from this study, illustrate several cross-national similarities regarding the ways in which secondary students perceive school climate and the influence of school climate on student mental health. These findings can support school psychologists' efforts to identify strategies and …
Assessment of Entrepreneurial Orientation in Vocational Training Students: Development of a New Scale and Relationships With Self-Efficacy and Person…
2019
Having emerged as an important concept in the organizational field, entrepreneurial orientation has also become a key idea in the context of education. Indeed, entrepreneurial education is now one of the common objectives for education and training systems in the European Union. Despite its importance, however, there is a scarcity of valid and reliable measures for assessing entrepreneurial orientation in students. The present study aimed to address this by developing and examining the psychometric properties of the Entrepreneurial Orientation Scale (EOS). A second objective is to study the relationships between entrepreneurial orientation and gender, self-efficacy, and personal initiative.…
The Schoolwork Engagement Inventory: Factorial Structure, Measurement Invariance by Gender and Educational Level, and Convergent Validity in Secondar…
2017
This study analyzes the dimensionality, reliability, metric invariance, and convergent validity of the Schoolwork Engagement Inventory (SEI) in secondary education. Participants in the study were 679 students in compulsory and post-compulsory secondary education in a large city in Eastern Spain during the 2014-2015 academic year. Confirmatory factor analysis (CFA) showed that the one-factor model of the SEI is superior to the other alternative models considered, providing an overall schoolwork engagement score in this educational stage. Reliability was also adequate and the instrument was found to be invariant by gender and educational level. Latent mean comparisons revealed a significant …
Measurement of the lifetime difference in the B$_s^0$ system
2005
We present a study of the decay B_s^0 -> J/psi phi We obtain the CP-odd fraction in the final state at time zero, R_perp = 0.16 +/- 0.10 (stat) +/- 0.02 (syst), the average lifetime of the (B_s, B_sbar) system, tau (B_s^0) =1.39^{+0.13}_{-0.16} (stat) ^{+0.01}_{-0.02} (syst) ps, and the relative width difference between the heavy and light mass eigenstates, Delta Gamma/Gamma = (Gamma_L - Gamma_H)/Gamma =0.24^{+0.28}_{-0.38} (stat) ^{+0.03}_{-0.04} (syst). With the additional constraint from the world average of the B_s^0$lifetime measurements using semileptonic decays, we find tau (B_s^0)= 1.39 +/- 0.06 ~ps and Delta Gamma/\Gamma = 0.25^{+0.14}_{-0.15}. For the ratio of the B_s^0 and B^0 li…
Improving Harris corner selection strategy
2011
This study describes a corner selection strategy based on the Harris approach. Corners are usually defined as interest points for which intensity variation in the principal directions is locally maximised, as response from a filter given by the linear combination of the determinant and the trace of the autocorrelation matrix. The Harris corner detector, in its original definition, is only rotationally invariant, but scale-invariant and affine-covariant extensions have been developed. As one of the main drawbacks, corner detector performances are influenced by two user-given parameters: the linear combination coefficient and the response filter threshold. The main idea of the authors' approa…
The Italian version of the Cognitive Style Indicator and its association with decision-making preferences
2018
By adopting a more flexible view, Cools and Van den Broeck (2007) developed the Cognitive Style Indicator (CoSI) which includes three cognitive dimensions: Creating (flexible, open-ended and inventive), Knowing (emphasizing facts, details, objectivity, and rationality), and Planning (guided by preferences for certainty and well-structured information). The first aim of this research was to validate the three factor structure of the CoSI within the Italian context, whereas the second was to verify whether cognitive styles, as measured by the CoSI, accounted for individual differences in decision-making processes. Two studies were conducted using two different samples (n = 549 and n = 397). C…
