From planetary to societal boundaries: an argument for collectively defined self-limitation

Self-adjoint, globally defined Hamiltonian operators for systems with boundaries

For a general self-adjoint Hamiltonian operator H0, defined on the Hilbert space L (IRn), we determine the set of all self-adjoint Hamiltonians H on L(IRn) that (dynamically) confine the system to an open set S ⊂ IRn while reproducing the action of H0 on an appropriate domain. We propose strategies for constructing these Hamiltonians explicitly and for n = 1 we prove that an important class amo...

An Argument for Argument Ellipsis from -sika NPIs

Ideology, Irrationality and Collectively Self-defeating Behavior

One of the most persistent legacies of Karl Marx and the Young Hegelians has been the centrality of the concept of “ideology” in contemporary social criticism. The concept was introduced in order to account for a very specific phenomenon, viz. the fact that individuals often participate in maintaining and reproducing institutions under which they are oppressed or exploited. In the extreme, thes...

Assessing Argument Diagrams in an Ill-defined Domain

This paper describes a study in which student-created diagrams about arguments in an ill-defined domain were manually graded by two independent human graders. Findings include that the graders overall agreed with each other on their grades, but their agreement was lower than one would expect in well-defined domains, and higher for solutions of extreme quality.

An Analytical Study on Boundaries of Administrative-defined Neighborhoods Using Residents’ Cognitive Maps (Case study: Mashhad Municipality Neighborhoods, Iran)

The neighborhood has had a long history in Iranian urbanization. Since urban plans wereintroduced by the authorities to shape urban development in Iran half a century ago, the concept of Iranian traditional neighborhood has been neglected gradually. The concept of neighborhood has not found the appropriate status in urban design and planning yet. One of the main reasons is that academics, profe...
