Following the framework in Oliva et al. 1987, GEMCAT II implements a flexible method to test catastrophe models containing multivariate (i.e., latent) variables while allowing for a priori variable specifications. The system uses an efficient hybrid minimization algorithm combining the Downhill...

The current study contributes to the already substantial scholarly literature on telecommuting by estimating a joint model of three dimensions—option, choice and frequency of telecommuting. In doing so, we focus on workers who are not self-employed workers and who have a primary work place...

Economic development, population growth, urbanization and climate change have led to an increasing water shortage across the globe. Ensuring water security under changing environment will be the greatest challenge for water resources managers in near future. In this paper, catastrophe theory...

Drought is one of the major disasters around the world which cause great social and economic hardship. Recent events of severe droughts have motivated comprehensive research on drought management in China like many other countries of Asia, Europe and Africa. In this paper, the mechanism of...

Twenty years ago, in my third thesis (Degos, 1991), I mentioned the problem of the formation of the opinion of the statutory auditor, and I used the catastrophe theory of René Thom. I persisted in this way with a working paper (1995) and a book [Degos, (1996), pp.171-183]. I regret not being...

This paper uses a response surface based on catastrophe theory to examine the interaction of information and profitability estimates on the firm's adoption of a new technology or innovation. As such, the paper builds on the conceptual ideas behind McCardle's (1985) work. An illustrative example...

The role of an intermediate metastable state in the fluctuation-induced transitions between two stable states is analyzed using generic kinetic models involving one and two order parameters. Conditions are identified under which the transition rate can be enhanced by the presence of the...

The new Hungarian Labour Code allows informal payments to be accepted, subject only to the prior permission of the employer. In Hungary, the area most affected is Health Care, where informal payments to medical staff are common. The article assesses the practice on ethical terms, focusing on...
