We frame social interaction as a problem in real-time system's identification and control. System's identification refers to the task of identifying the properties of a system we are trying to control. Control refers to the problem of sending an input sequence to a system in order to maximize expected returns with respect to desired goals. The brain faces a control problem when sending motor co...

Falling seriously ill is often experienced as a life event that causes conflict with people's personal goals and expectations in life and evokes existential questions. This article presents a new humanities approach to the way people make meaning of such events and how this influences their quality of life. Incorporating theories on contingency, narrative identity, and quality of life, we devel...

In this paper, we develop and present a contingency model of leadership and psychological empowerment that specifies the circumstances and situations under which follower self-leadership should be encouraged. The model suggests that certain key contingency factors, including follower development, situational urgency and task structure, dictate which of several leadership approaches, including d...

The paper exposes a non-parametric approach to latent and co-latent modeling of bivariate data, based upon alternating minimization of the Kullback-Leibler divergence (EM algorithm) for complete log-linear models. For categorical data, the iterative algorithm generates a soft clustering of both rows and columns of the contingency table. Well-known results are systematically revisited, and some ...

Abstract In this paper, we introduce our preliminary work in developing an analytic framework which allows us to contrast the problem of developing ‘web-like applications’ (WLAs) against our accumulated understanding of software systems development. The analytic framework will form a basis for the development of a contingent approach to selection of methods, tools and techniques, then integrati...

As the consumer e-commerce market grows intensively competitive, the strategy in retaining new customers at their first visits to a website has been recognized as a critical research issue. Not only does the customer’s initial acceptance of a website capture business opportunities, it also casts great impact on customers’ return purchases in the future and their loyalty buildup. From a continge...

Power system real time security assessment is one of the fundamental modules of the electricity markets. Typically, when a contingency occurs, it is required that security assessment and enhancement module shall be ready for action within about 20 min time to meet the real time requirement. The recent California black out again highlighted the importance of system security. This paper proposed ...

In power system reliability assessment, the system security limits and adequacy indices depend on the set of contingencies analyzed. Consequently the final solution strategies for short term operational and long term investment planning studies also depend on the set of contingencies considered for planning. Generally, planning is done for the most critical contingency, with the assumption that...
