Self-esteem, dispositional optimism, and health: Evidence from cross-lagged data on employees

2004

Abstract The aims of this one-year follow-up study among Finnish employees ( n =426) were twofold: first, to investigate the relationship between self-esteem and optimism and, second, to examine the prospective relationships between these two personality constructs, mental distress and physical symptoms. The results of Confirmatory Factor Analysis (CFA) showed that the latent variables of optimism and self-esteem were highly interrelated (Time 1, r =.90, Time 2, r =.87), forming the core construct of personal resilience, which turned out to be stable (stability coefficient .86) over the one-year period. The results of Structural Equation Modelling (SEM) indicated that high personal resilien…

The effectiveness of increased support in reading and its relationship to teachers' affect and children's motivation

2016

Abstract The aims of this study were, firstly, to identify different groups of teacher–child dyads on the basis of the longitudinal associations between teachers' individual support in reading and children's reading skills, and, secondly, to examine whether the groups thus identified differ with respect to various teacher- and child-related factors. A total of 372 teacher–child dyads were examined. The reading skills of 6- to 7-year-old Finnish-speaking children were measured at the beginning and end of Grade 1. The amount of teachers' support in reading for a particular child was gathered from teachers by questionnaires. Regression Mixture Modeling identified three latent groups of teacher…

Reservoir computing model of prefrontal cortex creates novel combinations of previous navigation sequences from hippocampal place-cell replay with sp…

2019

As rats learn to search for multiple sources of food or water in a complex environment, they generate increasingly efficient trajectories between reward sites. Such spatial navigation capacity involves the replay of hippocampal place-cells during awake states, generating small sequences of spatially related place-cell activity that we call “snippets”. These snippets occur primarily during sharp-wave-ripples (SWRs). Here we focus on the role of such replay events, as the animal is learning a traveling salesperson task (TSP) across multiple trials. We hypothesize that snippet replay generates synthetic data that can substantially expand and restructure the experience available and make learni…

The coach-created motivational climate influences variations in athletes’ motivation and emotional experiences. The present study aimed to examine social environmental antecedents of athletes’ emotions. Participants (N = 262, 52% female, M age = 22.75 ± 6.92) completed questionnaires assessing perceptions of coach-created motivational climates, goal orientations, motivation regulations, and emotions. The mediation effects of goal orientations (i.e., task/ego) and motivation regulations (i.e., autonomous/controlled) on the relationship between motivational climate (i.e., empowering/disempowering) and emotions (i.e., happiness, excitement, anxiety, dejection, and anger) were examined. Structu…

Social media users’ online subjective well-being and fatigue: A network heterogeneity perspective

2021

Scholars have drawn increasing attention to the implications of the dark side of social media for users’ online subjective well-being (OSWB). We develop a research framework based on the limited-capacity model to examine the relationship between OSWB and social media fatigue. Moreover, we explore the associations between specific aspects related to network heterogeneity and social media fatigue for social media users in the United States of America (USA). Further, we examine the mediating effect of network heterogeneity on the association between OSWB and social media fatigue. We utilised a cross-sectional research design to collect data from Prolific Academic (N = 320) and analysed the dat…

Aportaciones de la teoría de la autodeterminación a la predicción de la satisfacción escolar en estudiantes universitarios

2019

La literatura especializada ofrece evidencias de que en todo el mundo las tasas de deserción universitaria son elevadas, generando inconvenientes para los propios estudiantes, para la institución a la que pertenecen y para la sociedad en general. Los determinantes del abandono de los estudios son diversos, considerando uno de los más importantes la satisfacción de los estudiantes con su entorno educativo. La satisfacción académica de los estudiantes depende en gran medida del clima motivacional del aula y de la satisfacción de las necesidades psicológicas básicas, fundamento de la teoría de la autodeterminación. En el marco teórico de la motivación autodeterminada y de la psicología positiv…

Representing social intelligence: An agent-based modeling application

2017

Abstract Intelligent systems are composed of autonomous components that interact each others, with and through the environment, in order to give intelligent support for reaching specific objectives. In such kind of systems the environment is an active part of the system itself and provides input for runtime changing and adaptation. Modeling and representing systems like this is a hard task. In this paper we propose a biologically inspired approach that combined with the use of Agent-Based Modeling allows to create a means for analyzing emergent needs of the system at runtime and converting them into useful intelligent services to be provided. The experiment proposed for validating and illus…

Role Satisfaction Mediates the Relation between Role Ambiguity and Social Loafing among Elite Women Handball Players

2010

The aims of the study were to develop a questionnaire on self-reported social loafing (SRSLQ), and then to examine its relations with role ambiguity and role satisfaction in a sample of 110 women handball players competing at the elite level in Norway. Structural equation modeling analyses indicated that the SRSLQ was a psychometrically sound measure. In line with the expectations, role satisfaction fully mediated the positive relation between role ambiguity and self-reported social loafing: The more players experienced role ambiguity, the less satisfied they were with their role in the team, and the more social loafing they reported.

Social network loyalty: evaluating the role of attitude, perceived risk and satisfaction

2013

PurposeThe aim of this paper is to analyse the determinants of social networking site loyalty, paying special attention to the roles of user attitude, perceived risk and satisfaction.Design/methodology/approachThe impact of uses and gratifications of social networking sites, attitude, perceived risks and satisfaction on social networking site loyalty is tested through structural equation modelling techniques. The sample consisted of 811 Spanish social networking site users collected through a personal survey. Risk is measured as a formative construct.FindingsData analysis shows that attitude is a key variable in increasing satisfaction and loyalty towards social networking sites. Sociabilit…

The predicting role of self-efficacyin the Job Demands-Resources Model: A longitudinal study

2012

AbstractTaking Albert Bandura's Social Cognitive Theory as our starting point, we analysed the predicting role of self-efficacy in the Job Demands-Resources Model. We tested longitudinally the two underlying psychological processes, namely: 1) the motivational process, in which job resources (i.e., job autonomy and social support climate) foster engagement, and 2) the erosion process, in which high job demands (i.e., quantitative overload and role conflict) lead to burnout. Structural equation modelling in a sample of 274 secondary-school teachers confirmed both processes, as well as the powerful predicting role of self-efficacy. Finally, we discuss the theoretical findings and the practica…
