The biogeography of speciation remains a controversial issue and the process of allopatric speciation reigns. Sympatric speciation differs from allopatric speciation in terms of geographic setting and the role of selection in bringing about reproductive isolating mechanisms, making it a particularly fascinating and controversial subject for evolutionary biologists. Mayr (1947) explained the dif...

“WHERE WERE YOU? Andy has asked to see you several times,” my friend Karen (one of our nurses) greeted me as I walked into our Palliative Care Unit. “Why? What is bothering him? Is he in pain?” “No! Just wants to see you, I guess. He is transitioning you know . . . ” Transitioning is a euphemism for active dying often used on our unit. “Have you called his family yet?” I asked, knowing full wel...

We provide a sound theory for the computation of allocations of indivisible resources amongst cooperative agents, maximising the egalitarian social welfare of the overall multi-agent system, seen as a society. Agents’ preferences over resources are captured by scalar utilities that we sum up to define the agents’ individual welfare. The egalitarian social welfare is defined as the minimal indiv...

Just what is the Cooperative Society? You can have one for coffee or for maize, or for wheat flour or whatever can sit until next week and then be sold, but not for cabbage or other vegetables that will spoil tomorrow. It just can't work, or it could only work if they had an airplane to send the produce to Europe or America where there is a very high price. But who will agree to allow the Socie...

Association rules identify associations among data items and were introduced in 1993 by Agarwal et al.. Most of the algorithms to find association rules deal with the static databases. There are very few algorithms that deal with dynamic databases. The most classical algorithm to find association rules in dynamic database is Borders algorithm. This paper presents two modified version of the Bor...

Political borders are controversial and contested spaces. In an attempt to better understand movement along and through political borders, we applied the metaphor of a membrane to look at how people, ideas, and things “move” through a border. More specifically, we employed this metaphor in a system dynamics framework to construct a computer model to assess legal and illegal migration on the US-...

Chlamydia trachomatis (CT) is the most common cause of bacterial sexually transmitted infection (STI) worldwide, but current data concerning the prevalence of CT among women in Iran is scarce. Data regarding the frequency of CT infection among Iranian women can help to justify the implementation of a national CT screening program that can reduce the high morbidity associated with sequelae of CT...

Received: 17 October 2005 Accepted: 17 October 2005 Online publication date: 15 December 2005 Abstract We make the case for fresh approaches to examine the role of trust in international collaborations, based on the idea that not only do the levels of trust differ across international borders but also both the nature of trust and the institutional and cultural support for trust can vary across ...

The recent 25th anniversary of the fall of the Berlin Wall serves to remind us that sometimes “falling walls” are needed to solve differences not only between nations but also among the different disciplines of science. This need is underscored by a recent paradigm shift in research approaches to address multilayer and multistage research problems. This shift has seen a gradual transition from ...
