Rooting out the Rumor Culprit from Suspects
, 2013 Suppose that a rumor originating from a single source among a set of suspects spreads in a network, how to root out this rumor source? With the a priori knowledge of suspect nodes and an observation of infected nodes, we construct a maximum a posteriori (

Proceedings of the 2015 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining 2015, 2015 In this paper, we focus on the very specificity of rumors as pieces of information for modeling their process of propagation. We consider a population of pedestrians walking in a city and we assume that a rumor is transmitted by word of mouth from one to another.

Multisource Rumor Spreading with Network Coding [PDF]
IEEE INFOCOM 2019 - IEEE Conference on Computer Communications, 2019 The last decade has witnessed of a rising surge interest in Gossip protocols in distributed systems. In particular, as soon as there is a need to disseminate events, they become a key functional building block due to their scalability, robustness and fault tolerance under high churn. However, Gossip protocols are known to be bandwidth intensive. A huge

Proposing a Framework to Center Justice in Ambitious Science Teaching
Science Education, EarlyView.ABSTRACT Though educators and researchers have developed shared theory and language for priorities necessary to disrupt the status quo toward more equitable science education, we lack a tool that organizes sets of teaching practices across an instructional unit to support enactment and rehearsal.

DEStech Transactions on Computer Science and Engineering, 2017 It is the key factor to restrain rumor spreading, purify the environment of network and promote network harmony that deep studying the rumor spreading. The paper first discussed the serious harmfulness of rumor spreading to society. Then, from the social media types, model research methods, model structure, research theory and whether the relationship ...

Symbols of Climate Action: Audit Labor and the Production of Carbon Credits
Economic Anthropology, EarlyView.ABSTRACT Voluntary carbon markets (VCMs) are promoted as tools for financing climate mitigation, yet their effectiveness and credibility remain contested. This article examines how carbon credits are produced and destabilized as symbols of climate action, emphasizing the forms of ecological and audit labor that sustain their legitimacy.

Global stability of a SEIR rumor spreading model with demographics on scale-free networks
Advances in Difference Equations, 2017 In this paper, a new SEIR (susceptible-exposed-infected-removed) rumor spreading model with demographics on scale-free networks is proposed and investigated. Then the basic reproductive number R 0 $R_{0}$ and equilibria are obtained.
