RESEARCH

Kyosuke (pronounced KYO-s-kay ) studies the nature and future of workplace relationships. He uses experiments and field data to address research questions. (see my dissertation (pdf)).

1. Examining the role of formal and informal structures in realized interactions in teams and organizations
2. Quantifying an individual ability to effectively navigate their social network
3. Examining how and why people misperceive and miss communication links in communication networks
4. Developing an R package and method to quantify imaginary network motifs between observed and perceived networks, in collaboration with George G. Vega Yon
5. Investigating cognitive representations of "who bullies whom" in school classrooms

1. What's a nice Japanese guy like me doing in a place like Denmark?

We examined how self- and peer-reported bully-victim relationships overlapped as a function of the sex of bullies and victims, friendship ties, and relational schemas. Using network data obtained from 438 fifth-grade student in 13 Indonesian elementary school classrooms, we found greater agreement when bully-victim relationships occurred between non-friends. When self- and peer-reports disagreed, peers identified more instances of boys engaging in bullying than girls, as well as more cross-sex than same-sex bully-victim relationships.

We developed a theory and method to examine dyadic patterns of true and false positives and negatives in cognitive social structures (CSS). Using the method, we found mutual omission and commission (termed "completely false") could occur in CSS data. This mutual case is especially more prevalent in proxy reports than self-reported ties.

We examined how effectively space crew members and mission support can share information as needed in their communication network under different communication delay conditions. Our results show that network acuity (i.e., an individual ability to leverage their perceptions of the network to route information effectively) among crew members is higher than mission support, especially under communication delays.

Whereas the benefit of creating a new contact directly goes to you, increasing communication frequency with your existing contact can benefit your partner or neighbors. Our findings are fairly consistent based on our simulations of networking approaches on a diverse set of real-world communication networks.

Using data-driven computer simulations, we study the effect of networking strategies on efficiency in communication networks. We found there is a clear trade-off between the studied networking strategies and efficiency.

Report

In this paper, we assess the impact of social media on social and economic development, using an analytical framework that draws on social networks and social learning. We particularly highlight the use of social media in developing countries.
