Many of the issues associated with the inefficiency and ineffectiveness of information systems development (ISD) have been attributed to the poor relationship between business and IT colleagues. Relational issues relating to collaboration and communication before, during and after ISD lead to dissatisfaction with information systems and services. To address these relational issues, many organis...

We prove that the existence of a Kähler-Einstein metric on a Fano manifold is equivalent to the properness of the energy functionals defined by Bando, Chen, Ding, Mabuchi and Tian on the set of Kähler metrics with positive Ricci curvature. We also prove that these energy functionals are bounded from below on this set if and only if one of them is. This answers two questions raised by X.-X. Chen...

This paper reviews the trends and identifies the determinants of income inequality in Korea from 1980 to 2012. Both Kuznets’ hypothesis of inverted U-shaped relationship between income inequality and economic growth and Barro’s hypothesis of U-shaped relationship are not empirically supported. Macroeconomic index such as the government spending as a share of GNI was found to be statistically in...

The popularity of new media channels in recent decade has offered fertile ground for electronic word-of-mouth (eWOM) communication. By enabling interaction between organizations and customers, eWOM communication may increase organizations’ capability of customer engagement (CE). Despite the acknowledged importance of eWOM as an important new channel for customer engagement in tourism industry, ...

The purpose of this research is to develop a model that would close the gap between marketing plans and strategies from one side and the advanced online collaboration applications platforms known as WEB 2.0 in order to implement marketing 2.0 smoothly without disrupting the working environment. We started by examining published articles related to marketing, Web 2.0, Customer Relationship Manag...

We propose to demonstrate a system that helps enterprises manage their social Customer Relationship Management (CRM) presence. Our system performs deep analytics over consumer posts and authors to help companies monitor their CRM presence, and to identify and respond to actionable posts. In this paper we share challenges and experiences in building this system. Findings yield a step change in t...

We prove all the maximizers of the sharp Hardy-Littlewood-Sobolev inequality are smooth. More generally, we show all the nonnegative critical functions are smooth, radial with respect to some points and strictly decreasing in the radial direction. In particular, we resolve all the cases left open by previous works of Chen, Li and Ou on the corresponding integral systems.
