Managing of and reasoning about dynamic processes is a central aspect of much activity in the office. WC present a brief dcscrintion of our view of office systems and why change is of central importance in the office. A description system used to describe the structure of the office and office activity is discussed. A viewpoint mechanism within the description system is prcscntcd and we discuss...

On the other hand internet stores are providing services customized by the needs and interests of individual customers. Such services can be viewed as “seller’s agents” whose goal is to push merchandise and/or services on to the users. This le...

BACKGROUND Previous studies have demonstrated a correlation between diet cost and adherence to nutritional recommendations among consumers in general. This has adverse effects on diet and health inequality. It could be hypothesized that consumers knowledgeable in nutrition escape this correlation. OBJECTIVE Investigate whether the previously observed relationship between diet cost and nutriti...

BACKGROUND In recent years, analyses of event related potentials/fields have moved from the selection of a few components and peaks to a mass-univariate approach in which the whole data space is analyzed. Such extensive testing increases the number of false positives and correction for multiple comparisons is needed. METHOD Here we review all cluster-based correction for multiple comparison m...

BACKGROUND Testing for clustering at multiple ranges within a single dataset is a common practice in spatial epidemiology. It is not documented whether this approach has an impact on the type 1 error rate. METHODS We estimated the family-wise error rate (FWE) for the difference in Ripley's K functions test, when testing at an increasing number of ranges at an alpha-level of 0.05. Case and con...

This study explores the dynamics of two monopoly models with knowledgeable players. The first model was initially introduced by Naimzada and Ricchiuti, while second one is simplified famous Puu. We employ several tools based on symbolic computations to analyze local stability bifurcations models. To best our knowledge, complete conditions are obtained for time. investigate periodic solutions th...
