- How emotions influence trust in online transactions using new technologyTislar, C.; Sterkenburg, J.; Zhang, W.; Jeon, Myounghoon (SAGE Publications, 2014-01-01)Online trust has recently become a critical issue, due to widely publicized information leaks, account hacking, and privacy breaches. This study investigates whether or not emotions have effects on trust in online transactions, particularly when a new technology is involved. We explored the effects of happiness and sadness on participants' choice of a payment method for online transactions. Forty-four undergraduates participated in online transactions with a prototype webpage after either happiness or sadness induction, compared to a neutral group. Different emotion mechanisms would predict different effects of each emotion. Results showed that when the item cost was relatively low ($10), a higher percentage of participants in both emotion conditions selected a novel payment method than those in a neutral condition. With more expensive items ($50 and $100) the number of participants who chose the new option equally increased across all conditions because participants could benefit relatively a large amount of discount (10%) from the novel payment method. Various emotion mechanisms are discussed with our results.
- Hypothalamus-adipose tissue crosstalk: neuropeptide Y and the regulation of energy metabolismZhang, W.; Cline, Mark A.; Gilbert, Elizabeth R. (Biomed Central, 2014-06-10)Neuropeptide Y (NPY) is an orexigenic neuropeptide that plays a role in regulating adiposity by promoting energy storage in white adipose tissue and inhibiting brown adipose tissue activation in mammals. This review describes mechanisms underlying NPY’s effects on adipose tissue energy metabolism, with an emphasis on cellular proliferation, adipogenesis, lipid deposition, and lipolysis in white adipose tissue, and brown fat activation and thermogenesis. In general, NPY promotes adipocyte differentiation and lipid accumulation, leading to energy storage in adipose tissue, with effects mediated mainly through NPY receptor sub-types 1 and 2. This review highlights hypothalamus-sympathetic nervous system-adipose tissue innervation and adipose tissue-hypothalamus feedback loops as pathways underlying these effects. Potential sources of NPY that mediate adipose effects include the bloodstream, sympathetic nerve terminals that innervate the adipose tissue, as well as adipose tissue-derived cells. Understanding the role of central vs. peripherally-derived NPY in whole-body energy balance could shed light on mechanisms underlying the pathogenesis of obesity. This information may provide some insight into searching for alternative therapeutic strategies for the treatment of obesity and associated diseases.
