The thermally extended Tellinen model (Kühn et al., to appear) is here investigated and equipped with a hysteresis loss model, while preserving its simple structure.

As in the original model, these approaches are based upon phenomenal observations and measured saturation curves. The authors start with the original model and step-by-step add their extensions, such that in the end they can apply the extended model in a finite element method (FEM) simulation. During the process, care is taken to ensure that the applicability in a FEM simulation is not impaired, in terms of memory requirements and computing power.

In comparison to the original model, this extended model needs some further requirements and so is a little bit more limited in its application. It is in itself coherent and well defined. The authors provide an on-the-fly algorithm computation of hysteresis losses. First numerical results for a coupled field/thermal system show expected behavior.

The original model (Tellinen, 1998) does not take temperature into account. It includes a model for calculating hysteresis losses, but it differs largely from the approach presented here. The thermal extension is now also equipped with an on-the-fly method for hysteresis losses. Furthermore, the authors provide some analysis of simple, stable loops.

Philosophers and historians of science, along with scientists themselves, have long been interested in the problem of theory succession: “How does one theory supersede another?” Concern with this general topic has led to the development of two major recent theories regarding the issue. These theories of theory succession have emerged principally from reflection on physics. In the eyes of most scientists, this is probably appropriate, since physics seems to offer (at least to most observers) science in its purest form.

While a political activist organising Jewish workers in Galicia, before the First World War and in the Communist Workers' Party of Poland, between 1919 and 1925, Henryk Grossman wrote substantial Marxist works on the economic history of Galicia and Poland. His principal contributions to economic theory, from 1919 and into the 1940s, were the identification of Marx's method and the fundamental structure of Capital; the significance of the distinction between use value and value, at all levels of Marx’s economic analysis; and the elaboration of Marx's account of capitalism's tendency to break down and its consequent, unavoidable proneness to economic crises, grounded in the tendency for the rate of profit to fall and its counter-tendencies. While the reception of Grossman's analyses was generally hostile, they are of vital importance for those seeking to understand and overturn capitalism today.

The purpose of this paper is to analyze how path dependence in the evolution of major theories of foreign direct investment (FDI) locked in a theoretical perspective of the multinational enterprise that focused on asset-exploitation. This perspective is challenged by recent contradicting observations of multinationals from China and other emerging economies. A decisive re-orientation of FDI theory is proposed as a way forward to resolve this tension.

Placing FDI theories into the context of FDI patterns prevailing at the time they were developed, Thomas Kuhn’s framework on the evolution of scientific knowledge is employed to track how the mainstream FDI theory emerged, went through a period of normal science and then approached a crisis of science in this field.

The evolution of FDI theory is strongly path-dependent, which made it difficult for theory to effectively incorporate new conceptual discoveries and empirical findings about the nature of FDI activity.

FDI theory would benefit from a full re-orientation to a demand-oriented perspective which places the pursuit of advantages, assets, resources, etc., at the core of the theory. Such a change is implicit in many recent theoretical advances and would assure theory is generalizable to all types of FDI.

Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.
