Reasoning about graphs evolving over time is a challenging concept in many domains, such as bioinformatics, physics, and social networks. We consider common case which edges can be short term interactions (e.g., messaging) or long structural connections friendship). In practice, are often specified by humans. Human-specified both expensive to produce suboptimal for the downstream task. To allev...

This study examined friendship quality as a possible moderator of risk factors in predicting peer victimization and bullying. Children (50 boys and 49 girls, ages 10 to 13 years) reported on the quality of their best friendship, as well as their bullying and victimization tendencies. Parents reported on their child's internalizing and externalizing behaviors, in addition to bullying and victimi...

The current study examined the reciprocal associations between friendship attachment and relational experiences. Data came from a longitudinal study that assessed adolescents (N 1⁄4 223, 108 girls) in the 6th, 8th, 10th, and 12th grades. Cross-lagged models were fitted with structural equation modeling. Results showed that attachment avoidance was consistently predictive of more friendship excl...

This study investigated the relation of friendship and emotional adjustment in adolescents. Both quantitative (popularity, mutual friendships, and number of friends) and qualitative dimensions (perceived positive friendship quality and conflict) of friendship were used. Participants were 618, mostly European American, 8th-, 10th-, and 12th-graders. Structural equation modeling showed that posit...

Friendship plays a critical role in social commerce in contemporary societies. This study aims to theorize and examine how friendship quality impacts purchase intention. Product-related risk is introduced to gain insight into its moderating effects on intention to purchase from three different seller groups. Through empirical evidence, we confirm that friendship quality has positively effect on...

The cyclic entropy of a real virtual friendship network provides an insight on the degree of its robustness. Cyclic entropy depends on counting the number of cycles of different sizes in the network, in which a probability distribution function is resulted. Counting the number of cycles in the network is an NP problem. In this work we used a polynomial time approximation algorithm to count the ...

The authors examined associations of perceived similarity, actual similarity, and peer-rated similarity in personality with friendship intensity during the acquaintanceship process in a naturalistic setting. Self- and peer-rated personality data were gathered from undergraduates (mean age = 18.9) at 5 time points during the first year of university using a round-robin design. Whereas perceived ...
