We develop a class of examples in the form of tiling dynamical systems for use as toy models in statistical mechanics, to analyze the possible existence of disordered crystals. We give the first such models which are disordered in the sense of having no discrete spectrum. * Research supported in part by a grant from the Israel Science and Technology Ministry ** Research supported in part by NSF...

Contentious issues have frequently been overlooked in the study of international relations and interstate conflict. This chapter explores the influence of territory and territorial issues on processes of interstate conflict. I begin by reviewing existing approaches to the study of territory, and existing theoretical efforts to understand the role of territory. I then offer an empirical investig...

 Relations between the third world countries in different parts of Asia and Africa during the 19th and 20th centuries, to a great extent, were influenced by the presence and policies of colonial powers. Thus, for a better understanding of roots of disputes and issues existing between these countries concerning frontiers, disputed Islands, political and prejudicial tensions, we need to study pas...

Ortony and Turner's (1990) arguments against those who adopt the view that there are basic emotions are challenged. The evidence on universals in expression and in physiology strongly sug~ests that ~he~e is a biological basis to the emotions that have been studied. Ortony and Turner's reviews of thls hterature are faulted, and their alternative theoretical explanations do not fit the evidence. ...

It is currently postulated that not all obese individuals have to be considered as pathological subjects. From 10% to 20% of obese people studied do not show the metabolic changes common in obese patients. The term "healthy obese" has been coined to refer to these patients and differentiate them from the larger and more common group of pathological obese subjects. However, the definition of "he...

Children in the back seat on a long trip are not the only ones asking the question “Are we there yet?” At Murray State University (MSU) and other universities starting new programs, the question becomes one of validation of the program. In the late 90s, MSU, a midsize university, was entrusted with the responsibility of developing a program of distinction with financial support from special sta...

Statistical approaches to Artificial Intelligence are behind most success stories of the field in the past decade. The idea of generating non-trivial behaviour by analysing vast amounts of data has enabled recommendation systems, search engines, spam filters, optical character recognition, machine translation and speech recognition, among other things. As we celebrate the spectacular achievemen...

There has been a remarkable growth in evolutionary economics since the 1980s. But despite this outward success there has been inner disagreement on fundamental issues including the building blocks of evolutionary theory and the very meaning of ‘evolution’ itself. This essay provides a philosophical perspective on both the defining agreements and ongoing disputes within evolutionary economics. I...

In this communication we take up the age-old problem of the possibility to incorporate quantum jumps. Unusually, we investigate quantum jumps in an extended quantum setting, but one of rigorous mathematical significance. The general background for this formulation originates in the Balslev-Combes theorem for dilatation analytic Hamiltonians and associated complex symmetric representations. The ...
