Discussions on target theory: past and present

Target theory is one of the essential concepts for understanding radiation biology. Although many complex interpretations of target theory have been developed, its fundamental principle is that ‘inactivation of the target(s) inside an organism by radiation results in the organism’s death’. The number of ‘targets’ and the locations of these ‘targets’ inside an organism are not always clear, alth...

Further discussions on a possible lattice chiral gauge theory

In a possible SUL(2) lattice chiral gauge theory with a large multifermion coupling, we try to further clarify the threshold phenomenon: the possibility that the right-handed three-fermion state turns into the virtual states of its constituents (free chiral fermions) in the low-energy limit. Provided this phenomenon occurs, we discuss the chiral gauge coupling, Ward identities and the gauge ano...

Online Case Discussions: an activity theory perspective

In this paper we present a perspective of case discussions in an online learning environment based on Activity Theory, which allows us to analyse the embedded nature of students’ learning activities. We see Activity Theory as a first step towards structuring the complexity of students’ experiences in today’s higher education systems, recognising the distinction between potential and actual lear...

Session 12 Hierarchical Systems Theory

The design and analysis of large and complex system requires frequently that the system is divided into smaller units, called sub-systems. The structure of overall system resulting from the interconnections of sub-systems can be very complex. One of the most common structures, is the hierarchical structure, i.e. the lay-out of the structure is vertical. Consequently in this report only hierarch...
