RESEARCH

Kyosuke (pronounced KYO-s-kay ) studies communication structures and dynamics that lead to effective coordination among members of a group and organization. He uses experiments and field data to address research questions. (see my dissertation (pdf)).

Current Research Projects:

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

Seriously Unserious Project:

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

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.

Tanaka, K., DeChurch, L. A., & Contractor, N. S. (2020). The impact of network acuity on information sharing under communication delays in space multiteam systems. Proceedings of the International Astronautical Congress.

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.

Ackland, R., & Tanaka, K. (2015). Development impact of social media. WDR 2016 Background Paper.

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.
