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 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 ...

Difficulties in friendships have been reported both in people with Autism Spectrum Disorder (ASD) and in individuals with Anorexia Nervosa (AN). This small-scale qualitative study aimed to evaluate the friendship experiences of seven patients with AN who presented with possible ASD traits; to determine whether their experiences were reflective of those found in people with ASD, and whether any ...

This position paper explores the dual nature of friendship relations as an enabler but also as a pitfall for privacy in social networks. The privacy-deteriorating consequences of unilateral friendship disclosure are quantified for an existing medium-sized social network site. A lightweight implementation of hidden friendship using existing standards is proposed and assessed for practicable and ...

A friendship graph is a graph in which every two distinct vertices have exactly one common neighbor. All finite friendship graphs are known, each of them consists of triangles having a common vertex. We extend friendship graphs to two-graphs, a two-graph being an ordered pair G = (G0, G1) of edge-disjoint graphs G0 and G1 on the same vertex-set V (G0) = V (G1). One may think that the edges of G...

Friendship: Development in a Historical Perspective Friendship is a relationship that has existed across historical times in all types of societies. In developmental psychology, Piaget’s classical distinction between voluntary and symmetrical peerand friendship relationships and the asymmetrical and—due to its biological nature—compulsory parent–child relationship is still valid. However, given...
