Instant messenger (IM) is one of the most popular Internet applications all over the world. This paper examines the pricing problem of IM based on two-sided market model. IM serves as a two-sided platform, which gets both Internet users and advertisers on board. This paper concludes that IM operator adopts a heavily skewed price structure that favors IM users both under monopolistic case and under horizontal differentiated duopolistic case. When advertising revenue is large enough relatively to marginal cost for serving IM users, IM users can enjoy free service provided by IM operators. The competitive equilibrium of duopolistic case is not necessarily symmetric when advertisers choose singlehoming. Even in the symmetric equilibrium platform would rather deter all advertisers.

There are very few surveys conducted worldwide regarding internet users' opinions about internet regulation. What's more, the authors have already discussed the importance of measuring public opinion around the world in their endeavour to design and propose a fair IRS that will be accepted by the internet users at a national level. In this chapter, the authors discuss the design of their questionnaire and how it was evolved from the initial 2007 UK questionnaire to the current one that was used for conducting surveys in six different countries. This chapter presents the procedure that was used for collecting responses and what kinds of “safeguard” measures were taken in order to avoid deterioration of the gathered survey data. What's more, the analysis procedure of the gathered data is being presented, and the authors discuss the possibility of biased questionnaires and how the latter can be tackled further in future research.

The U.S

The so-called “Internet revolution” has dramatically changed the way people communicate and work nowadays. Attending to The Word Factbook developed by the U.S. Central Intelligence Agency (CIA), there are 1,018,057,389 Internet users in the world by 2005 (CIA, 2006). Fostering of the Internet revolution from a business perspective is out of question and the evergrowing number of Web functionalities has implied a significant and dramatic change in all business management areas. Within these areas, this revolution has not gone unnoticed, particularly for human resources management. Mentoring, which has been used as a tool for human capital development leverage in organizations has also been deeply impacted by the emergence and generalized use of Internet technologies giving birth to the so-called “e-mentoring.” The origins of the term must be looked for in Ancient Greece. In the Homer masterwork “Odyssey,” Ulysses, king of Ithaca, recommends mentor Alcímida his house, properties, and his son, Telemachus, education on leaving for the Troy War (traditionally dated from 1193 BC-1183 BC). Apart from the word ethimology, several modern disciplines literature (such as management, social psychology, sociology, or knowledge management) have provided with mentoring studies from the late seventies of the XX century, particularly, from the mid-nineties. As a consequence of the growing interest of the topic and its broad application in business ecosystems, thousands of definitions have popped up, trying to cover the semantics of the concept. Due to the aforementioned popularity of the concept, Friday and Green (2004) accomplish a re-conceptualization of the term stemming from a deep and detailed study about existing literature definitions. Subsequently, a definition for the mentoring concept is provided, aiming at being universal, following the authors goal: Mentoring is a guidance process that takes place between a mentor and a protégé (also known as mentee). Authors define similarly the mentor term as “wise and trusted counselor or teacher.”
