We describe the CoJACK cognitive architecture. It is designed to provide an intuitive, high level behaviour representation language that exhibits variability across individuals and across time for use in synthetic environments. The included moderator layer enables modelling of physiological factors and affect. We report initial results of an investigation of variability and time-based moderatio...

The volatility of output and inflation has varied substantially across countries and over time. While the global economy was very turbulent in the 1970s, macroeconomic volatility declined sharply in the following years in what has been termed the ‘Great Moderation’. This decline took place to different extents in different countries. In the United States, for example, the Great Moderation is us...

© 2005 Society for the Study of Addiction Addiction, 100 , 293–298 challenge could now be made to leaders in the alcohol treatment field in the United States. Low-risk drinking outcomes are a documented pathway to recovery in the United States as in other countries. Importantly, having moderation services available could facilitate such recoveries. Yet, advocacy for such services, even by gover...

This paper shows that within-country happiness inequality has fallen in the majority of countries that have experienced positive income growth over the last forty years, in particular in developed countries. This new stylized fact comes as an addition to the Easterlin paradox, which states that the time trend in average happiness is flat during episodes of long-run income growth. This mean-pres...

The paper examines the processes underlying economic fluctuations by investigating the volatility moderation of U.S. economy in the early 1980’s. We decompose the volatility decline using a dynamic factor framework into a common stochastic trend, common transitory component and idiosyncratic components. We find that the moderation of business cycle was a result of the moderation in transitory a...

We resurrect the question if improved business practices contributed to increased macroeconomic stability since the 1980s – the Great Moderation. While previous studies on the issue are limited to examining inventory management, we analyse the role of better supply chain management on enhancing firms’ ability to coordinate their production. By investigating ordering and backordering behaviour i...

Introduction BNCT is an effective method to destroy brain tumoral cells while sparing the healthy tissues. The recommended flux for epithermal neutrons is 109 n/cm2s, which has the most effectiveness on deep-seated tumors. In this paper, it is indicated that using D-T neutron source and optimizing of Beam Shaping Assembly (BSA) leads to treating brain tumors in a reasonable time where all IAEA ...

Investigating the fit of an information technology to a user’s task, known as task-technology fit (TTF), is a frequent focus of HCI/MIS research. In such research, “fit as moderation”, one of Venkatraman’s (1989) six conceptualizations of fit, is common. This conceptualization assumes two variables, e.g., task and technology, and an outcome variable. Task and technology, however, have multiple ...
