The Number of Alternative Products and the Information about it on the Online Shop

As the Internet can aggregate and distribute a great amount of information to users, providing numerous products for consumers has been recognized as a major advantage of electronic commerce. Causing by the problem of information overload, however, consumers facing many alternatives on the online shop may feel hard to decide which one they prefer. Based on the theory of decision style and prospect theory, this study explores if too many products sold on the online shop will reduce consumers’ subjective status toward their buying decision. A 3×3 between subjects experiment was conducted and showed that the buyers’ decision style, the quantity of alternative products and the information about it will affect consumers’ subjective status. These results suggest that we should consider the role of electronic intermediaries more carefully, and further examine the theory of information overload and the need for information literacy to prepare for the future

Management of mother-to-child transmission of hepatitis B virus: Propositions and challenges

AbstractChronic hepatitis B virus (HBV) infection due to mother-to-child transmission (MTCT) during perinatal period remains an important global health problem. Despite standard passive–active immunoprophylaxis with hepatitis B immunoglobulin (HBIG) and hepatitis B vaccine in neonates, up to 9% of newborns still acquire HBV infection, especially these from hepatitis B e antigen (HBeAg) positive mothers. Management of HBV infection in pregnancy still need to draw careful attention because of some controversial aspects, including the failure of passive-active immunoprophylaxis in a fraction of newborns, the effect and necessity of periodical hepatitis B immunoglobulin (HBIG) injection to the mothers, the safety of antiviral prophylaxis with nucleoside/nucleotide analogs, the benefit of different delivery ways, and the safety of breastfeeding. In this review, we highlight these unsettled issues of preventive strategies in perinatal period, and we further aim to provide an optimal approach to the management of preventing MTCT of HBV infection
