Digital currencies have emerged as a new fascinating phenomenon in the financial markets. Recent events on the most popular of the digital currencies--BitCoin--have risen crucial questions about behavior of its exchange rates and they offer a field to study dynamics of the market which consists practically only of speculative traders with no fundamentalists as there is no fundamental value to the currency. In the paper, we connect two phenomena of the latest years--digital currencies, namely BitCoin, and search queries on Google Trends and Wikipedia--and study their relationship. We show that not only are the search queries and the prices connected but there also exists a pronounced asymmetry between the effect of an increased interest in the currency while being above or below its trend value.
Internet technology has brought many changes in the society. In the Web 2.0 era, the role of common customers in business has changed largely. Consumers have become more influential on sales or new item development by enterprises through Internet (weblogs dasiablogspsila, forums, personal web pages, wikis, podcasts, social bookmarks, RSS feeds and other forms of many-to-many publishing). In some extent, Web 2.0 facilitates the construction of the autonomous decentralized network ldquooutsiderdquo enterprises. This network is constituted by each autonomous customers and supplier. In this paper, we describe a new wave of organization model ldquoinsiderdquo enterprises. Yumenomachi Souzou Iinkai is one successful enterprise on Internet portal business in Japan. The companypsilas main manner of management is to respect the autonomy of the employees. Most of the current staffs have intention to be independent and initiate their own Internet business company in the future. The CEO, Ms. Nakamura, also has been encouraging their ambitions to grow the company as a virtual cluster of new Internet businesses owned by the current employees. The case indicates a new enterprise model based on an autonomous decentralized organization.
In electronic commerce, the intraorganizational coordination of directly responsible units, for example profit centers or firms within an affiliated group, is of increasing importance. These organizational units can be modeled within a multiagent system (MAS), an interconnection of autonomous information systems. In this article, we investigate coordination mechanisms for MAS in decentralized transportation planning that ensure efficient allocation of scarce resources on the basis of local planning processes. In the domain of transportation, planning problems are characterized by large amounts of data, limitations of time for planning, and the intractability of computational problems. Auctions as market-like coordination mechanisms are discussed with respect to the trade-off between theoretical evidence on the quality of the allocation and computational tractability. Therefore, 2 pricing mechanisms are investigated, the generalized Vickrey auction and pricing per column.

Most directors of marketing intuitively know that accepting some business has an opportunity cost of not being able to accept potentially more lucrative business. The decision becomes particularly critical when the prospective contract is for a large event, such as a conference. Some hotels address this matter by, for instance, requiring executive committee approval for all large contracts or all business that involves function space. The decision can be made much earlier and more simply by individual sales representatives or sales managers, however, if they analyze the tradeoffs of any potential contract. An analytical approach can be built into a spreadsheet calculation that takes into account such variables as special room rates, potential banquet revenues and costs, and revenues and costs of other services (e.g., audio-visual support). The decision is more than quantitative, however, and must take into account such factors as the effect on other guests' perceptions of the hotel if, say, facilities are jammed by conventioneers. Those effects cannot be modeled on a spreadsheet and are subject to the marketing director's judgment.
