EBC Division Lecture Series in Penn State Berks feature Drs. Lokshina and Yang
The Engineering, Business, and Computing (EBC) Division Speaker Series in Penn State Berks feature visiting experts who conduct research on a variety of topics. On March 21, 2014, the EBC Division Speaker Series will feature Dr. Izabella Lokshina, Chair and Professor of MIS and Dr. Jing Yang, Assistant Professor of MIS from School of Economics and Business at SUNY Oneonta.
Dr. Lokshina will lecture on “Algorithms for accelerated rare event simulation with Markov chain modeling in communication networks”. According to Dr. Lokshina, two efficient rare event simulation algorithms, based on the importance sampling and cross-entropy methods, are developed and applied to accelerate the overflow probability simulation with Markov chains in wireless communication networks. Recommended approach is appropriate and particularly efficient being used for reliability and performance evaluation in wireless communication networks, while more reliable networks must be described by rarer events.
Dr. Yang will talk about “Reading the voice in seller reviews: an analysis on the trust feeling revealed in reviews”. Her presentation specifically analyzes the trust feeling embedded in seller reviews and its impacts on customers’ perceived uncertainty and perceived risks in online transactions, based on the findings in a text mining over 500 reviews collected from ebay.com. She concludes that seller reviews can be fairly explained by the trust feeling exposed in their content and the three antecedents of trust (benevolence, competence and integrity) have a significant impact on perceived seller opportunism and uncertainty in online transactions.
