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…
Using random networks to study the dynamics of respiratory syncytial virus (RSV) in the Spanish region of Valencia
2011
[EN] Seasonal fluctuations in the incidence of several respiratory infections are a feature of epidemiological surveys all around the world. This phenomenon is characteristic of influenza and respiratory syncytial virus pandemics. However, the explanation of the seasonal outbreaks of these diseases remains poorly understood. Many statistical studies have been carried out in order to provide a correlation of the outbreaks with climatic or social factors without achieving a definitive conclusion. Here we show that, in a random social network, self-sustained seasonal epidemics emerge as a process modulated by the infection probability and the immunity period after recovering from the infection…
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…
Customer Loyalty in Clusters: Perceived Value and Satisfaction as Antecedents
2009
Purpose: This paper studies, from the perspective of relationship marketing, the loyalty behavior of industrial customers in the context of a cluster. Loyalty is a key variable for studying long term relationships between firms. Research implications: Recent advances in consumer and services marketing consider that perceived value and satisfaction are central to explaining customer loyalty. However, very few studies in B2B explain the antecedents of customer loyalty. This study adopts the relationship marketing approach, and loyalty behavior is being analyzed in a specific setting: an industrial cluster. Furthermore, the effect of the number of suppliers is analyzed as a possible moderator …
Interindividual Differences in Treatment Effects based on Structural Equation Models with Latent Variables: An EffectLiteR Tutorial
2019
The investigation of interindividual differences in the effects of a treatment is challenging, because many constructs-of-interest in psychological research such as depression or anxiety are latent variables and modeling heterogeneity in treatment effects requires interactions and potentially nonlinear relationships. In this paper, we present a tutorial of the EffectLiteR approach (Mayer, Dietzfelbinger, Rosseel, & Steyer, 2016) that allows for estimating individual treatment effects based on latent variable models. We describe step by step how to apply the approach using the EffectLiteR software package with data from the multicenter randomized controlled trial of the Social Phobia…
The Influence of Parents on Achievement Orientation and Motivation for Sport of Adolescent Athletes with and without Disabilities
2011
The purpose was three-fold. First, to analyze the psychometric properties of scales used. Second, to test the relationship among athletes’ perceptions of parents’ goal orientation and their own goal orientation and intrinsic motivation. Third, to compare athletes with and without disabilities with respect to the influence of parents on athletes’ achievement orientation and motivation for sport. Participants were 173 amateur athletes (80 with disabilities, 93 without disabilities). Structural equation models revealed that for the athletes with disabilities, task orientation and the perceptions of parents’ task orientation were related to athletes’ interestenjoyment and effort-importance. For…
