Group cohesion, needs satisfaction, and self-regulated learning: A one-year prospective study of elite youth soccer players' perceptions of their clu…

2018

Abstract Objectives With an overarching aim of investigating the importance of group perceptions on factors believed to underpin the quantity and quality of athletic practice, the purpose of the present study was to examine the relationship between perceptions of group cohesion and elite youth soccer players' basic psychological needs satisfaction and self-regulation over a one-year period. Design Prospective study design involving data collection at two time-points over a one-year period. Method A total of 332 elite youth soccer players selected at Norwegian regional U14 (N = 154) and U 13 (N = 178) levels completed questionnaires measuring perceptions of club-team cohesion, and individual…

Knowledge Sharing Among Tourists via Social Media: A Comparison Between Facebook and TripAdvisor

2016

This paper examines tourists' knowledge sharing behavior in social media. Based on social capital theory, we aim to examine the effects of three dimensions of social capital—structural (social interaction ties), cognitive (shared vision) and relational (trust)—for two different types of social media: Facebook and TripAdvisor. We propose a structural model that connects an antecedent (homophily) and a consequence (knowledge sharing through posting) of these main dimensions of social capital. An online survey is conducted with 1200 Spanish consumers. Based on the full sample, our structural equation modeling supports most of the hypothesized paths, while trust does not affect either social in…

This study investigates the role of context-specific authenticity at work for work-related outcomes (intrinsic motivation, work ability) and depressivity. Furthermore reciprocal relations between work-related authenticity and healthy psychological functioning are investigated. Longitudinal data from 1,243 employees from 63 subsidiaries of a non-profit organisation in the social sector were analysed using multilevel structural equation modelling. Work-related authenticity at T1 predicted work ability and depressivity, but not intrinsic motivation at T2, about 6 months later. Work-related authenticity at T2 was predicted by intrinsic motivation and depressivity, but not by work ability at T1.…

Reciprocal relations between autonomous motivation from self-determination theory and social cognition constructs from the theory of planned behavior…

2020

Abstract Objectives The present study examined reciprocal relations between autonomous motivation from self-determination theory (SDT) and constructs from the theory of planned behavior (TPB) in a sport injury context. Methods The study adopted a three-wave longitudinal cross-lagged panel design. Physical education students in China (N = 4414; Mage = 14.42, SD = 1.75) completed self-report measures of autonomous motivation, attitude, subjective norm, and perceived behavioral control with respect to sport injury prevention at baseline (T1) and at two follow-up occasions one (T2) and three (T3) months later. Proposed reciprocal relations between autonomous motivation and the TPB constructs co…

Victimisation and school violence. The role of the motivation ofrevenge, avoidance, and benevolence in adolescents.

2019

Abstract The aim of the present study is to explore the relation among school victimisation and school violence, taking into account the motivations of revenge, avoidance, and benevolence. The sample includes 671 adolescents of both sexes, between 10 and 16 years old, attending primary and secondary school. The structural equation model, calculated with EQS software, show that victimisation is directly and indirectly related to school violence through revenge motivation. Victimisation is also related to avoidance and benevolence motivations, although these are not associated with school violence. Multigroup analysis indicates statistically significant differences between boys and girls in t…

Generating Executable Code from High-Level Social or Socio-Ecological Model Descriptions

2019

Agent-Based Modelling has been used for social simulation because of the several benefits it entails. Social models are often constructed by inter-disciplinary teams that include subject-matter experts with no programming skills. These experts are typically involved in the creation of the conceptual model, but not the verification or validation of the simulation model. The Overview, Design concepts, and Details (ODD) protocol has emerged as a way of presenting a model at a high level of abstraction and as an effort towards improving the reproducibility of Agent-Based Models (ABMs) but it is typically written after a model has been completed. This paper reverses the process and provides non-…

An Interactive Framework for Offline Data-Driven Multiobjective Optimization

2020

We propose a framework for solving offline data-driven multiobjective optimization problems in an interactive manner. No new data becomes available when solving offline problems. We fit surrogate models to the data to enable optimization, which introduces uncertainty. The framework incorporates preference information from a decision maker in two aspects to direct the solution process. Firstly, the decision maker can guide the optimization by providing preferences for objectives. Secondly, the framework features a novel technique for the decision maker to also express preferences related to maximum acceptable uncertainty in the solutions as preferred ranges of uncertainty. In this way, the d…

Is Small Still Beautiful for the Strengths and Difficulties Questionnaire? Novel Findings Using Exploratory Structural Equation Modeling.

2020

Article first published online: June 17, 2018 During the present decade a large body of research has employed confirmatory factor analysis (CFA) to evaluate the factor structure of the Strengths and Difficulties Questionnaire (SDQ) across multiple languages and cultures. However, because CFA can produce strongly biased estimations when the population cross-loadings differ meaningfully from zero, it may not be the most appropriate framework to model the SDQ responses. With this in mind, the current study sought to assess the factorial structure of the SDQ using the more flexible exploratory structural equation modeling approach. Using a large-scale Spanish sample composed of 67,253 youths ag…
