uncovering social media Reaction Pattern to protest events a spatiotemporal dynamics perspective of ferguson unrest
Social Informatics, 2015Co-Authors: Lingzi Hong, Vanessa Friasmartinez, Paul M TorrensAbstract:Social platforms like Twitter play an important role in people’s participation in social events. Utilizing big social media data to uncover people’s Reaction to social protests can shed lights on understanding the event progress and the attitudes of normal people. In this study, we aim to explore the use of Twitter during protests using Ferguson unrest as an example from multiple perspectives of space, time and content. We conduct an in-depth analysis to unpack the social media response and event dynamics from a spatiotemporal perspective and to evaluate the social media Reaction through the integration of spatiotemporal tweeting behavior and tweet text. We propose to answer the following research questions. (1) What is the general spatiotemporal tweeting Patterns across the US? (2) What is the spatiotemporal tweeting Patterns in local St. Louis? (3) What are the Reaction Patterns in different US urban areas in space, time and content?

Unexpected transfer of tosyl group of ArCH=NTs-catalyzed by N-heterocyclic carbene.
The Journal of organic chemistry, 2008Co-Authors: Dong-dong Chen, Xue-long Hou, Li-xin DaiAbstract:Reactions of N-tosylimines with aziridines and electron-deficient unsaturated compounds in the presence of catalytic amount of NHC afforded unexpected tosyl group transfer products in good to high yields, which represent a new Reaction Pattern for imines as well as for catalysis of NHC.

sensitizing capacity and cross Reaction Pattern of the isomers of diglycidyl ether of bisphenol f in the guinea pig
Contact Dermatitis, 2002Co-Authors: Ann Ponten, Erik Zimerson, Osten Sorensen, M BruzeAbstract:: In this study, the sensitizing capacities of the 3 main low-molecular-weight isomers of epoxy resins based on diglycidyl ether of biphenol F (DGEBF) were investigated in a guinea pig maximization test (GPMT). The isomers are p,p'-DGEBF, o,p'-DGEBF, and o,o'-DGEBF. The sensitization capacities were compared to diglycidyl ether of bisphenol A (DGEBA), which is the main constituent in the most common epoxy resin. The cross-Reaction Pattern between all 4 compounds was also investigated. It was found that all 3 DGEBF isomers were potent sensitizers. It was also found that p,p'-DGEBF, o,p'-DGEBF, and DGEBA cross-reacted with one another, and that animals induced with o,o'-DGEBF reacted significantly only to o,p'-DGEBF, but not to the other 2 DGEBF isomers or DGEBA.
