A Bayesian actor-oriented multilevel relational event model with hypothesis testing procedures

Relational event network data are becoming increasingly available. Consequently, statistical models for such data have also surfaced. These models mainly focus on the analysis of single networks; while in many applications, multiple independent event sequences are observed, which are likely to display similar social interaction dynamics. Furthermore, statistical methods for testing hypotheses about social interaction behavior are underdeveloped. Therefore, the contribution of the current paper is twofold. First, we present a multilevel extension of the dynamic actor-oriented model, which allows researchers to model sender and receiver processes separately. The multilevel formulation enables principled probabilistic borrowing of information across networks to accurately estimate drivers of social dynamics. Second, a flexible methodology is proposed to test hypotheses about common and heterogeneous social interaction drivers across relational event sequences. Social interaction data between children and teachers in classrooms are used to showcase the methodology.</p

Implementing Belief-Consistent Multilevel Secure Relational Data Model: Issues and Solutions

This paper summarizes our efforts in implementing a working multi-level secure database prototype. We have chosen Belief-Consistent Multilevel Secure Relational Data Model (BCMLS) as a basis for our prototype because of its comprehensive semantics for interpreting all stored information. While semantically superior to other models, this model has not been implemented as a working system before. Our prototype, which was created on an Informix database server with a PHP web client, enables insertion, deletion and update of multi-level data while addressing the underlying model complexities through a number of original solutions

The Influence of Hospitality Leaders’ Relational Transparency on Followers’ Trust and Deviance Behaviors: Mediating Role of Behavioral Integrity

This paper investigates the effect of leader\u27s relational transparency on follower organizational deviance through followers’ perception of leader\u27s behavioral integrity and their trust in leader. Multi-level modeling results from a multisource survey-based field-study with 24 hospitality student project teams (N = 149) show that behavioral integrity mediates the relationship between leader\u27s relational transparency and follower\u27s trust in leader. Furthermore, multi-level path analysis suggests that leader\u27s relational transparency, a team-level construct, exerts a cross-level effect on follower\u27s organizational deviance through the mediating roles of behavioral integrity and follower\u27s trust in leader. The study has yielded theoretical and practical implications that are useful for hospitality leaders. © 201

Helping motivation and well-being of chronic pain couples: a daily diary study

Receiving support from a romantic partner may yield benefits for individuals with chronic pain (ICPs), but may also carry unintended side effects. The conditions under which partner support provision yields (mal) adaptive effects deserve greater attention. Grounded in Self-determination theory, partners may provide help for autonomous or volitional (eg, enjoyment, full commitment) or rather controlled or pressured (eg, avoiding guilt and criticism) motives. This study examined associations between day-to-day fluctuations in partners' type of helping motivation and several outcomes, among partners and ICPs. Seventy couples, with 1 partner having chronic pain (75.7% female), completed a diary for 14 consecutive days. Daily helping motivation was assessed together with daily affect, relational conflict, and relationship-based need satisfaction. Partners (M-age = 55.14) additionally reported on daily helping exhaustion, whereas ICPs (M-age = 54.71) reported on daily pain intensity, disability, satisfaction with received help, and amount of received help. Providing autonomous help related to improvements in partners' affective (eg, positive affect), relational (eg, conflict), and help-specific (eg, exhaustion) functioning, which were accounted for by improvements in daily relationship-based psychological need satisfaction. Similarly, daily autonomously motivated help yielded a direct (ie, relational conflict; perceived amount of help) or indirect (ie, positive and negative affects; relational conflict; satisfaction with help, disability) contribution in explaining ICP outcomes-through improvements in ICPs' relationship-based psychological need satisfaction. Findings highlight the importance of a motivational and dynamic perspective on help provision within chronic pain couples. Considering reasons why a partner provides help is important to understand when partners and ICPs may benefit from daily support

Effectiveness of Corporate Social Media Activities to Increase Relational Outcomes

This study applies social media analytics to investigate the impact of different corporate social media activities on user word of mouth and attitudinal loyalty. We conduct a multilevel analysis of approximately 5 million tweets regarding the main Twitter accounts of 28 large global companies. We empirically identify different social media activities in terms of social media management strategies (using social media management tools or the web-frontend client), account types (broadcasting or receiving information), and communicative approaches (conversational or disseminative). We find positive effects of social media management tools, broadcasting accounts, and conversational communication on public perception

The Role of Father Involvement and Marital Satisfaction in the Development of Family Interactive Abilities: A Multilevel Approach.

The study aims to investigate the development of family interactions from pregnancy to preschool age in a longitudinal perspective, using multilevel analysis. Also, it explored the impact of couple relationship and father involvement in childcare on the developmental trend of the quality of mother\u2013father\u2013child interactions. One hundred and three primiparous families were assessed at 7th month of pregnancy, 4th, 9th, and 18th months of child\u2019s life and during preschool age (36\u201348th), using the observational procedure named, Lausanne Trilogue Play. Parents\u2019 perception of marital satisfaction was assessed with the Dyadic Adjustment Scale at each point of measure; moreover, in the postnatal assessment, parents completed the Father Involvement Questionnaire. Results showed that family interactions increase over time. Secondly, a decrease of marital adjustment is associated with an improvement of the quality of family interactions. Moreover, father involvement predicts the quality of family interactions from the earliest stages of child\u2019s life. In a longitudinal perspective, family interactions and marital quality show opposite developmental trends and father\u2019s involvement represents a particularly important feature of the family

Ecological-transaction model approach of adolescents’ parental maltreatment and peer-bullying: the moderating role of bullying at the classroom

INTRODUCTION: The present study examined the ecological-transactional model delineated by Cicchetti and Lynch (1993) and the nature of the association between adolescents’ parental maltreatment and victimization and bullying at school. METHOD: Multivariate multilevel regression analyses were conducted on a sample of 2.852 adolescents between the ages of 12 and 17 from 25 secondary schools. Data was nested across 133 classrooms. Classrooms level variables and individual variables in relationship to parental maltreatment, behavioural disorders, sex, and bullying and victimization were included in the analysis. RESULTS: Results indicated that adolescents who reported suffering violence at home, showed more vulnerability to becoming victims of bullying at school, with the relationship being moderated by the level of bullying in the classroom. It was also examined the role of behavioural disorders and a relation between these factors was found amongst the bullies but not the victims. DISCUSSION AND CONCLUSION: This study uses the systemic perspective of ecological-transactional model on child maltreatment to show the importance between the school and home microsystems in the perpetuation of victimization. The results imply that what children experience at home might cause emotional and behavioural differences in varying classroom climates at school. Therefore, understanding the interactions between systems’ transaction of socialisation mechanisms might contribute for effective anti-bullying programs
