Pricing strategies of an oligopolist in federated cloud markets

In this paper, we study how an oligopolist influences the coalition structure in federated cloud markets. Specifically, we use cooperative game theory to model the circumstances under which a cloud provider prefers to join a cloud federation vis-a-vis consider taking a price offer made by an oligopolist. We consider two price offering strategies for an oligopolist: non-adaptive and adaptive. In non-adaptive strategy, an oligopolist makes a price offer to all the cloud providers simultaneously. It can be noted that the oligopolist can buy-out all the cloud providers by making a price offer which is equal to a core allocation and the total price offer made by the oligopolist is equal to the value of the grand coalition. In adaptive strategy, the oligopolist approaches the cloud providers one after another in a sequential manner. We show that by using the adaptive strategy, the oligopolist can buy-out all the cloud providers at a total price offer which is less than that of the non-adaptive strategy.

The Importance of Symmetry in Defining Caddo Relationships

Minich and Price offer insights into the way the Caddo participated in the Mississippian Culture sphere using both semiotics and symmetry analysis of surface designs on 150 ceramic vessels from three sites in the Ouachita and Red River valleys. Symmetry in surface designs persisted over 900 years of occupation in the Southern Caddo area, but the variety and distribution of dominant symmetry types changed over time and space, suggesting a local preference for, and symbolic association with, particular symmetry types. Variety in symmetry types increases through time and correlates with both changes in sociopolitical organization within individual Caddo communities and changes related to larger regional influences. While differences in design structure choice may reflect individual community identity, the overall continuity in form, style, and technique are factors that made Caddo ceramics symbolic of the cohesive nature of the Mississippian cultural tradition as a whole.

Nove norme i izbor odijela za zaštitu od kemijskih i bioloških opasnosti

SUMMARY: Selection of chemical protective clothing in industry is based on the known hazards. Firefighters and other intervention personnel face danger from many different hazardous chemicals which are usually not known in advance. On the whole, firefighters select the highest possible protection level offered by gastight suits. Their choice are frequently still reusable garments, although limited and single use garments, beside lower price, offer a number of important advantages in terms of weight, volume, chemical resistance, ease of maintenance, and comfort. New European norms do not divide chemical protective garments into reusable and limited use any more, which is in concert with the progress achieved in material technology. The issue of total lifecycle cost has become the decisive factor in the selection process. Following correct selection based on risk assessment is the maintenance specified in manufacturers’ recommendations, which is a critical factor in garment functionality. Modelling toxicity for new materials gives the opportunity for more precise risk assessment regarding permeation of dangerous chemicals and removes certain deficiencies in European norms. Some of most important parameters which must be analysed and compared during selection process are presented in the paper.
