Adaptation Model

Much of the literature thus far has tended to aggregate child soldiers with child terrorists. This chapter distinguishes between child soldiers and children involved in terrorist organizations focusing on the areas in which the two phenomena diverge. After describing key cases from history, the chapter will take a theoretical approach to understanding children and terrorism as a function of a “substitution effect” (from economic theory) that children step in when adults are no longer available to perform the same tasks and contrast it with a competitive adaptation model in which terrorist organizations adapt to changing circumstances and exploit children as a tactical innovation.

Recently we have developed a form of polarization microscopy that forms images using optical properties that have previously been limited to macroscopic samples. This has given us a new window into the distribution of structure on a microscopic scale. We have coined the name differential polarization microscopy to identify the images obtained that are due to certain polarization dependent effects. Differential polarization microscopy has its origins in various spectroscopic techniques that have been used to study longer range structures in solution as well as solids. The differential scattering of circularly polarized light has been shown to be dependent on the long range chiral order, both theoretically and experimentally. The same theoretical approach was used to show that images due to differential scattering of circularly polarized light will give images dependent on chiral structures. With large helices (greater than the wavelength of light) the pitch and radius of the helix could be measured directly from these images.

AbstractThe toxic leadership refers to destructive behaviours and leaders’ personal characteristics which cause serious damage to the subordinates and organizations. Still, what is toxic for the military in one country can be good in another one, given the cultural differences. This article wants to emphasize, from a theoretical approach, the main characteristics and effects of toxic leadership within the military organization.
