The role of daily autonomous and controlled educational goals in students’ academic emotion states: An experience sampling method approach

2018

The present study examines antecedents of university students' academic emotions (Pekrun, Goetz, Titz, & Perry, 2002) in the context of self-determination theory (SDT; Deci & Ryan, 1985; 2000), using realtime assessment and intra-individual analyses. We investigated whether daily autonomous and controlled-motivated educational goals predicted students' academic emotions. University students (N = 55) completed smartphone diaries over 14 consecutive days. The two-week intensive longitudinal data were organized in a hierarchical three-level structure, with situations (Level 1) nested within days (Level 2) nested within students (Level 3). Students' goal motivation was assessed in morning quest…

The Developmental Dynamics between Interest, Self-concept of Ability, and Academic Performance

2014

Abstract. Only a few studies have examined the direction of associations between academic achievement, interest, and sel f-concept of ability simultaneously by using longitudinal data over several school years. To exam ine the cross-lagged relationships between students’ interest, self-concept of ability, and performance in mathematics and reading, longitudinal data from Grade 1 to Grade 7 of comprehensive school was gathered from 216 students. The results showed that, in both reading and math, performance predicted students’ subsequent self-concept of ability. Some evidence was also found that math performance predicts subsequent interest in mathematics, and that self- concept of math abil…

Understanding the gender gap in STEM careers. A longitudinal data analysis

2019

Este trabajo presenta la aplicación de un análisis longitudinal a los datos del porcentaje de mujeres matriculadas en estudios relacionados con las disciplinas CTIM (STEM, por sus siglas en inglés) en la Escuela Técnica Superior de Ingeniería de la Universitat de València. El objetivo es evaluar el posible impacto del programa desarrollado desde 2011 en esta entidad para promocionar los estudios relacionados con la Ingeniería, especialmente entre las chicas.

Estimating the Bayesian posterior distribution of indirect effects in causal longitudinal mediation analysis

Many research studies aim to unveil the causal mechanism underlying a particular phenomenon; mediation analysis is increasingly used for this scope, and longitudinal data are particularly suited for mediation since they ensure the correct temporal order among variables and the time spanning allows the causal effects to unfold. This explains the rise of interest in the topic of longitudinal mediation analysis. Many approaches have been proposed to cope with longitudinal mediation (Fosen et al., 2005; Lin et al., 2017), among which mixed-effect modelling. In a recent paper, Bind et al. (Biostatistics, 2016) made use of generalised mixed effect models and provided conditions for the identifiab…

Combining Sequence Analysis and Hidden Markov Models in the Analysis of Complex Life Sequence Data

2018

Life course data often consists of multiple parallel sequences, one for each life domain of interest. Multichannel sequence analysis has been used for computing pairwise dissimilarities and finding clusters in this type of multichannel (or multidimensional) sequence data. Describing and visualizing such data is, however, often challenging. We propose an approach for compressing, interpreting, and visualizing the information within multichannel sequences by finding (1) groups of similar trajectories and (2) similar phases within trajectories belonging to the same group. For these tasks we combine multichannel sequence analysis and hidden Markov modelling. We illustrate this approach with an …

The story models of physiotherapy students’ professional development. Narrative research

2014

The aim of this article is to investigate students’ narratives about their professional development process. This research brings new kind of knowledge to continuing learning, developing education and planning the curriculum in physiotherapy education. The European Qualification Framework (EQF) defines learning competences in education; qualitative research has a narrative approach. The material consists of eight voluntarily participating physiotherapy students’ portfolios written during their whole study time. The longitudinal data describes them as learners and their development process. The major findings are four main episodes in professional development: the previous studies, a new way…

Parental ability attributions regarding children's academic performance: Person-oriented approach on longitudinal data

2017

The aim of this study was to identify subgroups of mothers and fathers who differ according to the patterns of causal attribution to ability for their children's academic success and failure across early school years. Moreover, the extent to which the mother and father of the same child share the same attribution pattern, and how the attribution patterns are associated with the parents' level of education, children's sex and children's academic performance was investigated. A total of 1721 mothers and 1198 fathers filled out a questionnaire concerning their child-related ability attributions when the children were in Grades 1–3. Five different attribution patterns were identified with laten…

A NEW INDEX OF POVERTY PERSISTENCE

2008

This paper proposes a new indicator of poverty persistence based on a synthesis of the temporal sequences of the years spent in poverty and non poverty, taking into account the order in which poverty spells follow each other. The index is a measure with cardinal properties and it allows not only the ranking of the individuals according to the duration of their poverty experience but also to measure the distance between any two individuals in the population. The index can be built up at individual level and it is also possible to have an aggregated index at any territorial level. Micro data from a longitudinal survey are needed.

Starting a new business later in life

2014

Self-employment in later life may be either a career option or a form of partial retirement. This paper adds knowledge about those individuals who start a business when they are older. A large longitudinal data set is utilized to examine the transitions of individuals aged 55–74 to self-employment in Finland. The significance of prior activity as well as personal, household, financial, and environmental characteristics is analyzed for the transitions. The results show that most of those entering self-employment in later life have prior self-employment experience, thus suggesting that entrepreneurship at later ages is often habitual. Habitual entrepreneurs deviate from novice entrepreneurs i…
