摘要: In capital market, earlier detection of the influential entities can be beneficial to both market investors’ and regulators’ decision making, those whose change can significantly affect the whole trend of the related ones. Meanwhile, market manipulation in capital markets is a serious concern, encompassing tactics like pump and dump, market cornering, spoofing, and wash trading, which disrupt market fairness and erode investor trust. Market manipulation encompasses a range of activities designed to artificially influence the price or trading volume. By leveraging both information behavior data(stock news opinion/volume) and business behavior(stock trading price/volume), together with trade patterns and communication channels, several herding based manipulation scenes and detection models are discussed and proposed.

摘要: Female fig wasps differ phenotypically from conspecific males to the extent that often they cannot be associated with one another. Weighted gene co-expression network analysis (WGCNA) of the genome and transcriptomes of one such fig wasp, Ceratosolensolmsi, generated five expression modules, which were flagged as blue, turquoise, brown, green and yellow. These involved two female-biased expression modules and three pupa-biased expression modules, respectively. Gene ontologies indicated three functional enrichment gene sets in modules turquoise and yellow. Two functional enrichment gene sets that participate in cell cycle or have nucleotide binding activityclustered in turquoise module. The functionally enriched gene set in yellow module played roles in cell differentiation, especially in neuron morphogenesis.

摘要: The article tries to discover the major authors in the field of information seeking behavior via social network analysis. It is to be accomplished through a literature review and also by focusing on a graphic map showing the seven most productive coauthors in this field. Based on these seven authors’ work, five probable research directions about information seeking behavior are discerned and presented.
