We address the problem of predicting the expected opinion share over a social network at a target time from the opinion diffusion data under the value-weighted voter model with multiple opinions. The value update algorithm ensures that it converges to a correct solution and the share prediction results outperform a simple linear extrapolation approximation when the available data is limited. We further show in an extreme case of complete network that the opinion with the highest value eventually takes over, and the expected share prediction problem with uniform opinion value is not well-defined and any opinion can win.
The mother of Hana Kimura, a cast member of Fuji Television's popular reality show "Terrace House," filed a complaint with a broadcast ethics watchdog Wednesday alleging a human rights violation over her daughter's death in May following cyberbullying. "Terrace House" came under heavy criticism and scrutiny after Kimura, a 22-year-old female professional wrestler who starred in the most recent season of the show, died in an apparent suicide. The show was also aired internationally on Netflix. Kyoko Kimura, 43, submitted documents to the Broadcasting Ethics & Program Improvement Organization claiming that the reality show was edited to present her daughter as a violent woman. Kyoko Kimura also asserts in the documents that the program continued shooting even when her daughter hyperventilated. Such actions by the show's staff violated her daughter's personal and human rights, she added.
We address the problem of efficiently estimating the influence function of initially activated nodes in a social network under the susceptible / infected / susceptible (SIS) model, a diffusion model where nodes are allowed to be activated multiple times. The computational complexity drastically increases because of this multiple activation property. We solve this problem by constructing a layered graph from the original social network with each layer added on top as the time proceeds, and applying the bond percolation with a pruning strategy. We show that the computational complexity of the proposed method is much smaller than the conventional naive probabilistic simulation method by a theoretical analysis and confirm this by applying the proposed method to two real world networks.
A lawmaker with severe physical disabilities highlighted the various difficulties disabled people encounter in their daily lives as she attended her first interpellation in the Diet on Tuesday since she was elected in July. "I want to ask questions so more rational considerations will be made" in society for people with disabilities, Eiko Kimura, who has cerebral palsy, said to the standing committee of land and transport. Kimura won a seat in the July 21 Upper House election as a member of Reiwa Shinsengumi, an anti-establishment political group founded in April by actor-turned-politician Taro Yamamoto. For roughly 30 minutes she raised questions about the barrier-free accessibility of evacuation shelters during typhoons and other natural disasters, as well as the availability of toilets for the disabled. According to the House of Councilors, it marks the first time a lawmaker requiring a wheelchair and an aide due to a disability has asked questions during an interpellation session.
A newly elected Upper House member who has severe physical disabilities has said that her presence as a lawmaker will help turn Japan into a country where the socially vulnerable can live comfortably. Eiko Kimura, 54, of the political group Reiwa Shinsengumi, also voiced concern Friday over the current welfare service system for people with disabilities, as commuting and other economic activities are not covered through public aid. "(For example) there's no system allowing lawmakers with severe disabilities to be at the Diet while receiving (necessary) care," said Kimura, who has cerebral palsy. Kimura and Yasuhiko Funago, a lawmaker from the same political group who has amyotrophic lateral sclerosis, received their certificates of election through proportional representation. "I'm just overwhelmed and speechless," Funago, 61, said through his caretaker.
