UNLABELLED The aim of this article is to assess the mental health status of inmates and people in custody in the state of Rio de Janeiro and the association between mental health and imprisonment using the Beck Depression Inventory and the Lipp Stress Symptom Inventory for Adults. SAMPLE 1,573 individuals, via stratified sampling with probability proportional to size. STUDY POPULATION more ...

Social Interactions and Labor Market Outcomes in Cities We develop a model where information about jobs is essentially obtained through friends and relatives, i.e. strong and weak ties. Workers commute to a business center to work and to interact with other people. We find that housing prices increase with the level of social interactions in the city because information about jobs is transmitte...

Social networks often provide only a binary perspective on social ties: two individuals are either connected or not. While sometimes external information can be used to infer the strength of social ties, access to such information may be restricted or impractical. Sintos and Tsaparas (KDD 2014) first suggested to infer the strength of social ties from the topology of the network alone, by lever...

We studied decentralized search in information networks and focused on the impact of network clustering on the findability of relevant information sources. We developed a multiagent system to simulate peer-to-peer networks, in which peers worked with one another to forward queries to targets containing relevant information, and evaluated the effectiveness, efficiency, and scalability of the dec...

Social media platforms like Facebook, Twitter, and LinkedIn let people broadcast messages to their entire network of contacts all at once. As the number of users and the amount of information they broadcast grow, platform managers face an increasingly pressing problem – which broadcasts should they show their users? To address this question, I study the database of a social media company that s...

This article examines the role of migrant social networks in international migration and extends prior research by testing the strength of tie theory, decomposing networks by sources and resources, and disentangling network effects from complementary explanations. Nearly all previous empirical research has ignored friendship ties and has largely neglected extended-family ties. Using longitudina...

A tie is a link between two persons in a social network. Here, we analyze tie strength in temporal co-authorship social networks by measuring ties persistence and transformation over time. Surprisingly, most ties tend to perish over time. Also, weak and random ties are more present in real co-authorship networks than bridges and strong ones.

We investigate gender homophily in the spatial proximity of children (6 to 12 years old) in a French primary school, using time-resolved data on face-to-face proximity recorded by means of wearable sensors. For strong ties, i.e., for pairs of children who interact more than a defined threshold, we find statistical evidence of gender preference that increases with grade. For weak ties, conversel...
